Description

Technical Field

[0001] This utility model relates to the field of folding bracket technology, and in particular to an aluminum folding bracket. Background Technology

[0002] Aluminum folding brackets are portable support devices primarily used to provide flexible support solutions. They can be folded for storage and portability, and are suitable for supporting products of varying widths to achieve optimal support. One existing aluminum folding bracket is used to support items such as clipboards, mobile phones, and books. When unfolded, the bracket engages with support clips in locking holes for angle adjustment. Simultaneously, pulling on two sets of supports, in conjunction with a central rotating frame, allows the bracket to be adjusted to a specific width.

[0003] However, it still has the following drawbacks in practical use:

[0004] Existing folding brackets lack a positioning structure when the rotating frame is opened, making them susceptible to external influences that can cause changes in the opening width, leading to the supported items falling off, affecting user experience, and even causing property damage. Utility Model Content

[0005] The purpose of this utility model is to provide an aluminum folding bracket to solve the problem mentioned in the background art, where the existing folding bracket lacks a positioning structure after opening, making it susceptible to external influences, causing the opening width to change, resulting in the supported items falling off, affecting user use, and even causing property damage.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model is an aluminum folding bracket, comprising:

[0008] The main component includes a first rotating frame and a second rotating frame;

[0009] The first rotating frame and the second rotating frame are rotatably connected at the middle.

[0010] A positioning assembly, comprising a spring post, an external thread, a first connecting ring, a second connecting ring, retaining teeth, and a through hole;

[0011] The fixed end of the spring column is glued to the middle of the lower surface of the first rotating frame, and the external thread is opened on the outer surface of the movable end of the spring column. The first connecting ring is fixed to the middle of the lower surface of the second rotating frame, and the through hole is opened in the middle of the second connecting ring. The second connecting ring is screwed to the external thread through the through hole, and the retaining teeth are respectively connected to the sides of the first connecting ring and the second connecting ring.

[0012] Furthermore, the second rotating frame is sleeved on the fixed end of the spring column, and the locking teeth on the first connecting ring and the second connecting ring are interlocked.

[0013] Furthermore, the main component also includes a base, a baffle, and a snap-fit ​​hole;

[0014] The base consists of two sets, which are placed on the workbench. The baffle is cut and connected to one end of the base in one go. There are six snap-fit ​​holes, which are opened at the end of the base away from the baffle.

[0015] Furthermore, the main component also includes a bracket, a support rod, and a movable hole;

[0016] The bracket is rotatably connected to the end of the base near the baffle. The upper end of the support rod is hinged to the middle side of the lower surface of the bracket, and the lower end of the support rod is engaged in the engagement hole. The movable hole is located on the bracket away from the connection point with the base.

[0017] Furthermore, the main component also includes four rotating shafts, which are respectively fixed to the upper surfaces of the first rotating frame and the second rotating frame at both ends;

[0018] Two of the shafts are rotatably connected to the bracket near the baffle, while the other two shafts are movably connected inside the movable hole.

[0019] Furthermore, it also includes clamping components;

[0020] The clamping assembly includes a square hole and a lever;

[0021] The square hole is opened in the middle of the side of one of the brackets, and one end of the lever is inserted into the square hole.

[0022] Furthermore, the clamping assembly also includes a collar and a circular spring;

[0023] The collar is fitted onto the middle section of the rotating shaft located in the movable hole of the second rotating frame. The collar and the lever are injection molded in one piece. The two ends of the round spring are connected to the upper surface of the second rotating frame and the lower surface of the collar by screws.

[0024] Compared with existing technologies, the advantages of this utility model are:

[0025] I. This utility model, through the positioning component, allows the second connecting ring to be pulled before the bracket is opened, causing the spring column to stretch. Then, the second connecting ring is rotated, causing the through hole to move downwards along the external thread, thereby moving the second connecting ring downwards and releasing it. At this point, the locking teeth on the second connecting ring and the first connecting ring disengage, allowing the bracket to be pulled to rotate the first and second rotating frames. When the bracket is opened to the required width, the second connecting ring is pulled and rotated in the opposite direction, locking the first and second connecting rings together. This design positions the first and second rotating frames, preventing changes in the width of the bracket after it is opened.

[0026] II. In this utility model, by setting a clamping component, when the bracket is opened, the push block in the square hole is pressed down, which drives the collar to move downward. After the bracket is opened, the push block is released, and under the action of the round spring, the collar is pressed against the lower surface of the bracket. This setting can increase the stability of the rotating shaft in the movable hole. Attached Figure Description
