Can display the picture on both sides at the same time, to save space and maximize the efficiency of advertising!Double sided flip flops are a type of flip flop, which can achieve the effect of double-sided display. The image of the double-sided flip flop is installed on both sides of the flip flop, and the image is hung on a support rod in the middle. The double-sided flip flop is a bracket and promotional image installed in a box, and the support frame is designed as a magazine. The image can be retracted from both sides, and when used, it can be pulled out of the box. The support rod is also placed in the box and pulled out, usually consisting of three sections, Hollow, with ropes connected inside, connecting them together to form a support rod, the box becomes the base, and the screen can be unfolded and hung from the top to the top of the support rod. When not in use, the screen can be retracted into the box, and the support rod can also be folded up, and then placed in a long cylindrical bag for walking. This is the advantage and characteristic of the double-sided flip flop as a portable exhibition stand: easy to carry and easy to install.

March 15 this year coincides with the first anniversary of the implementation of the new Consumer Law. Although the new consumer law has protected consumers' greater interests, due to the various regulations that have not yet been introduced, it is still more troublesome for consumers to suffer quality problems. If consumers can pay more attention to consumption traps before consumption or consumption, many disputes can be avoided. Therefore, in March this year, in cooperation with Guangdong Industrial and Commercial Bureau, Guangdong Product Quality Supervision and Inspection Institute, Guangzhou Fiber Products Testing and Research Institute, Weikai Testing Technology Co., Ltd., Saibao Quality and Safety Testing Center, 4 small items (including mobile phone Accessories, switch sockets, car lights, lighting appliances) give consumer tips, I hope consumers can be more comfortable and more assured in the purchase. Lighting appliances: Compared with incandescent lamps, LED bulbs have high luminous efficiency, low power consumption, long life, easy control, maintenance-free, safe and environmentally friendly, and are more and more popular among consumers. However, many LED bulbs do not have the legendary eye protection function, and may cause damage if not purchased properly. Xu Yiquan, lighting room engineer of Guangdong Product Quality Supervision and Inspection Institute, said that consumers should first look at the appearance of LED bulbs when purchasing LED bulbs. The lamp body should not have sharp edges, burrs and the like. Abnormal sound. When purchasing a light bulb, it is better to indicate the light effect is high. In addition, when testing the lamp, it should be seen whether the brightness of the lamp is stable and the color of the light is uniform. It is not glare and comfortable when the light is seen by the human eye. Touch the light bulb at work with your hand, and the temperature is low. In addition, in a quieter environment, listen to the sound of the LED bulb, if you can hear the sound of the bulb very clearly, it means that the drive power of the bulb is not very good. Huang Canlin, an engineer in the lighting room of the Guangdong Product Quality Supervision and Inspection Institute, gave the consumer a small trick: some of the LED desk lamps sold in the market will have stroboscopic light, which will cause blue light damage to people. A simpler way to distinguish is to turn on the camera function of the smartphone to face the LED light. If there is strobe, there will be obvious ripples on the screen of the mobile phone; if there is no strobe, there will be no ripples. Mobile phone accessories: On March 4th, a girl in Shijiazhuang suddenly lost her voice when chatting with her boyfriend on a mobile phone. The boyfriend rushed to the girl's house and found that the girl had died and the heart was burnt. It was suspected that the electric shock was caused by the phone charging. Hu Yufei, an engineer at the Saibao Quality and Safety Testing Center of the Fifth Institute of Electronics, Ministry of Industry and Information Technology, said that in recent years, many cases of electric shocks when using mobile phones during charging were mostly caused by unqualified mobile phone chargers. In the first quarter of 2014, the Guangdong Provincial Administration for Industry and Commerce entrusted the National Communication Terminal Product Quality Supervision and Inspection Center to conduct quality monitoring of mobile phone and accessory products in the circulation area of ​​the province, and produced it in 131 enterprises sold in 11 provinces in the province. The inspection of 150 sets of commodities found that there were 52 qualified products and 98 unqualified products. The unqualified product discovery rate was 65.3, and the mobile phone charger sampling rate was as low as 10. Hu Yufei introduced that the mobile phone body is powered by DC low voltage (generally about 5V). In addition to the safety of the mobile phone battery, there is no other serious safety hazard in the mobile phone body. However, when the charger is used to charge the mobile phone, the charger is directly connected to the power supply of the grid (dangerous voltage: AC 220V). The quality of the charger directly affects the safety of the mobile phone users and the surrounding environment. The internal circuitry of a qualified mobile phone charger is designed to isolate the low voltage DC output from the hazardous mains supply to reduce the risk of electric shock to the handset user. If you use a charger with imperfect isolation measures or no isolation measures, the user may feel paralyzed and may even cause an electric shock to death. In addition, since the plug of the charger is directly connected to the dangerous grid power supply, the size of the metal plug on the charger and the distance from the metal latch to the accessible surface of the user have strict requirements. Hu Yufei suggested that consumers should be careful to buy chargers, purchase regular manufacturers' products through formal channels, and don't want to buy fake and shoddy products cheaply. When purchasing, you must purchase a product with a CCC mark, with product name, manufacturer, and back-shaped symbol. In addition, the purchased charger pins should conform to the Chinese standard. The flat pins have no opening shape, and the plugs have openings, cylindrical pins or some plastic materials on the pins, which are unqualified products. When using, pay attention to connect the mobile phone to the charger first and then plug the charger into the power supply of the grid; do not operate the mobile phone when charging; when the charging is finished, pull the charger out of the grid power supply in time.
