Clamping bracket

Abstract

A clamping bracket including a shell is disclosed. The shell is provided with first, second and third clamping arms. One end of each of the first, second and third clamping arms extends into the shell, and the other end extends out of the shell. The third clamping arm is a gravity carrier. The shell is provided with a rotary table linked with the third clamping arm. The third clamping arm moves upand down to drive the rotary table to rotate. Two symmetrical arc-shaped grooves are formed on the rotary table. The first clamping arm and the second clamping arm are fixedly provided with sliding columns, the sliding columns drive the first clamping arm and the second clamping arm to open and close in the arc-shaped grooves, and an elastic member is connected between the rotary table and the shell, and the elastic member drives the rotary table to rotate in the direction of making the first clamping arm and the second clamping arm close. The rotary table is additionally arranged as a linkage mechanism of the three clamping arms, which makes the connection between the three clamping arms compact, and the arc groove design on the rotary table is suitable for the linkage process to becomesmoother and more stable.

Description

technical field [0001] The invention relates to a bracket, in particular to a bracket that can hold electronic equipment, and is especially suitable for holding a mobile phone in a car. Background technique [0002] The car holder is the emergence of smartphones. Installing a holder that can hold a mobile phone in the car can facilitate the driver to use the functions of the smartphone, such as navigation functions. Since the development of the clamping bracket, various types have been derived. Among them, there is a gravity bracket that is active in the market due to its convenience in use. The so-called gravity bracket uses the gravity of the mobile phone itself to drive the clamping parts. The linked clamping part is generally composed of three clamping arms. When the mobile phone is placed in the bracket, under the action of gravity, the mobile phone will press one of the clamping arms downward, and the other two clamping arms will be linked together to shrink in the dir...

Problems solved by technology

Other clamping arm linkage methods are also disclosed in the prior art. For example, the cooperation between the clamping arms is linked by multiple gears, and even the gears between the clamping arms are omitted. For example, the patent number is 201720434753.2 and the name is simple As disclosed in the invention patent of the type meshing linkage rotating clamping bracket, the structure omitted between the clamping arms can reduce costs, but it also brings instability to the overall structure itself, which is not conducive to the long-term use of the product, especially in used in the car
