Description

Bracket Technical field

The present invention relates to a bracket, and more particularly to a bracket that is telescopic and can be rotated at a large angle and a long distance.

Background technique

With the rapid development of technology and economy, there are more and more types of electronic devices, and their functions are becoming more and more powerful. For example, mobile phones, tablets, e-books, electronic photo albums, and some communication devices such as car navigation systems and car computers all combine voice communication and multimedia functions, providing video, images, music, web browsing, conference calls, and others. Information services enable people to use these devices for a longer period of time in their lives.

These electronic devices, if held for a long time, may cause pain in the wrist or arm, pain in the neck and lumbar vertebrae, and thus affect the health of the people. Therefore, some brackets capable of holding and supporting these electronic devices have appeared. Such as the Chinese patent CN203181032U (patent number ZL201320196033.9) disclosed in the "bed multi-purpose retractable folding mobile phone holder", which includes a bed clip, a connecting rod and a mobile phone clip, the head of the bed clip can be rotated 360 degrees to accommodate more The clamped portion of the shape area, the connecting rod can be arbitrarily adjusted, stretched, bent and folded, and the clamping portion of the mobile phone clip can be respectively stretched outward while the mobile phone is placed. The mobile phone holder is suitable for people who are leaning against the bed for a long time while resting at home, and lying on the bed using the mobile phone. However, the mobile phone support of this kind has a small bearing capacity, the clamping of the bed clamp is not strong enough, and the connecting rod can only be lengthened to a limited extent, because once the connecting rod is lengthened, the support center of gravity of the entire bracket will be shifted forward to cause the bracket Dumping. Therefore, it can only be applied to the clamping and fixing of equipment such as short-distance, light-weight mobile phones. In addition, the range of application of the bed clamp is narrow, and it is often not easy to find the ideal clamping position, and it is not easy to use anywhere.

For example, the "vehicle bracket" disclosed in the Chinese patent CN201189846Y (Patent No. ZL200820093644.X) includes an adsorption member, and the base connected to the adsorption member is bently connected to the telescopic assembly, and the telescopic assembly is connected in rotation and swing in all directions. A mount for supporting automotive consumer electronics. The length of the vehicle bracket is retractable, which is convenient for adjusting the viewing distance of the vehicle electronic product. Although the vehicle bracket can adjust the vertical distance and angle of the electronic product, the telescopic component cannot realize 360 degree wide angle rotation, and thus can only be limited. The position of the electronic product is adjusted within the space range and can be used in a small space of the car. However, if the stent is transplanted for indoor use, its structure cannot meet the requirements of people who wish to adjust the distance and angle arbitrarily.

For example, the "an electronic device bracket" disclosed by the Chinese patent CN202834616U (patent number ZL201120415901.9) is mainly composed of an adjustable electronic device front end fixing bracket, a spherical universal adjusting mechanism, a lateral telescopic mechanism, and a right angle 360 degree rotating mechanism. Up and down telescopic mechanism, the base of the bracket, the structure can realize the adjustment of the distance and the angle of the electronic device, but the base of the bracket must be semi-permanently fixed, difficult to move and install, and it is difficult to meet the desire of people to use at different places at any time. Requirements. In addition, its adjustment angle only depends on the bracket 360 degrees The rotating mechanism and the spherical universal adjusting mechanism are not accurate and flexible in adjusting the angle and position, and the electronic device bracket has a complicated structure, and the length is adjusted only by the expansion and contraction of the lateral telescopic mechanism, so that the overall adjustment range is not particularly wide, and the rotation of the bracket is also Not particularly flexible.
