Description

Technical Field

[0001] The utility model relates to the technical field of folding brackets, in particular to an X-shaped bracket folding structure. Background Art

[0002] Folding stands are used in many fields, such as mobile phone folding stands, computer folding stands, book stands, display stands, etc. They have the advantage of not taking up space after folding. Folding stands generally have a base, a folding mechanism, and a support plate located on the top of the folding mechanism. Adjustment teeth are arranged on the base, and the folding mechanism cooperates with the adjustment teeth to realize the opening and closing of the folding stand. A Chinese patent discloses an X-shaped stand folding structure, announcement number: CN 221196811 U, the bottom of which slides in the slide groove of the adjustment teeth through the adjustment foot located at the bottom of the folding mechanism. The adjustment teeth are inclined. When opening, the adjustment foot slides along the inclined direction of the adjustment tooth. When closing, the adjustment foot slides into the slide groove to realize rapid opening and closing. However, this structure has only one set of hinge points between the support plate and the folding mechanism, and the angle adjustment is achieved through the friction between the support plate and the folding mechanism. It is generally suitable for smaller brackets, such as mobile phone brackets. However, for heavier brackets such as computer brackets, an X-shaped bracket is required. When the X-shaped bracket is opened, the adjustment foot will be pulled up and away from the adjustment teeth. In order to adjust the distance, you need to align the adjustment teeth with both hands and then press them into the adjustment teeth, which is difficult to operate. Moreover, in this structure, when closing the bracket, the adjustment foot will be pressed downward, making it difficult to move the adjustment teeth out of the adjustment teeth and closing them. Therefore, it is necessary to develop a bracket structure with high support strength, stable use, and easy opening and closing. Utility Model Content

[0024] The technical solution of the utility model is described below in conjunction with the accompanying drawings and embodiments.

[0025] Example 1: Reference Figures 1 to 8An X-shaped bracket folding structure includes a base 1, two groups of first connecting members 2 and second connecting members 3 hinged to each other, and a support plate 4. The base 1 is provided with two groups of adjusting tooth groups 5 corresponding to the second connecting members 3. The bottom of the first connecting member 2 is hinged to the top of the base 1, and the top of the first connecting member 2 is slidably connected to the support plate 4. The bottom of the support plate 4 is provided with a square groove 6, and the top of the first connecting member 2 slides in the square groove 6. The top of the second connecting member 3 is hinged to the bottom of the supporting plate 4, and the bottom of the second connecting member 3 is arranged in the adjusting tooth group 5. The adjusting tooth group 5 includes a tooth group body 51, and a plurality of adjusting teeth 52 are arranged at the bottom of the tooth group body 51. The two sides of the tooth group body 51 are respectively and relatively provided with an upper slide groove 53 and a lower slide groove 54 arranged up and down. The upper slide groove 53 and the lower slide groove 54 are arranged in parallel, and the upper slide groove 53 and the lower slide groove 54 are connected at both ends to form a ring. A sliding column 31 is provided at the bottom of the second connecting member 3, and the sliding column 31 protrudes from the side surface of the second connecting member 3. The sliding column 31 slides in the upper slide groove 53 or the lower slide groove 54. When the sliding column 31 slides in the upper slide groove 53, the bottom of the second connecting member 3 is disengaged from the adjusting teeth 52, and the second connecting member 3 can slide in the adjusting tooth group 5. When the sliding column 31 slides in the lower slide groove 54, the bottom of the second connecting member 3 is stuck in the adjusting teeth 52. A guide piece 7 is provided on the adjusting tooth set 5 and directly facing the second connecting member 3 . The function of the guide piece 7 is to lift the bottom of the second connecting member 3 so that the slide post 31 moves from the lower slide groove 54 to the upper slide groove 53 .

[0026] Specifically, a first torsion spring 8 is provided between the first connecting member 2 and the second connecting member 3, and the first torsion spring 8 enables the second connecting member 3 to rotate around the center of the first torsion spring 8, so that the bottom of the second connecting member 3 is pressed downward, thereby ensuring that the bottom of the second connecting member 3 is stuck in the adjusting tooth 52.

[0027] Specifically, a block 9 is hinged at the bottom of the second connecting member 3, and the block 9 replaces the bottom of the second connecting member 3 and is inserted into the adjusting tooth 52. The block 9 is provided with a limiting portion 91 to limit the rotation angle of the block 9. At the extreme rotation angle of the block 9, the bottom of the block 9 is just stuck in the adjusting tooth 52. A second torsion spring 10 is provided between the block 9 and the second connecting member 3. When the bracket is opened, the block 9 moves in the adjusting tooth 52, and the adjusting tooth 52 moves the block 9, so that the block 9 rotates and resets under the action of the second torsion spring 10, and hits the next adjusting tooth 52 during the resetting process. The block 9 and the adjusting tooth 52 are generally made of metal, and there can be a certain sound during the collision, and hearing the sound can also ensure that the block 9 is stuck in the adjusting tooth 52.

[0028] Specifically, the base 1 is rotatably connected to a bottom plate 11, and the base 1 and the bottom plate 11 bracket are rotatable. The specific structure of the rotatable connection is a conventional structure and will not be described in detail here.

[0029] Specifically, one side of the guide piece 7 is inclined and the other side is horizontally arranged. The inclined side is consistent with the inclination direction of the second connecting member 3, and the horizontal side is fixed to the adjusting tooth group 5 by bolts. When the bottom of the second connecting rod moves to the lower guide piece 7, the guide piece 7 lifts the bottom of the second connecting member 3 upward, so that it moves from the lower slide groove 54 located below to the upper slide groove 53.

[0030] Example 2: Reference Figures 9 and 10 , compared with the embodiment 1, the difference is that: the upper connection of the two second connecting members 3 is integrally arranged, the adjusting tooth group 5 is a group, the width is relatively wide, and the upper slide groove 53 and the lower slide groove 54 are arranged on both sides, and the two groups of the second connecting members 3 are respectively slidably connected with one group of the upper slide groove 53 or the lower slide groove 54, the width of the adjusting tooth group 5 is relatively wide, and the bottoms of the two groups of the second connecting members 3 are both arranged in the adjusting tooth group 5. The rest of the structure is the same as the embodiment 1, and will not be described in detail.

[0031] When the bracket is opened, the bottom of the second connecting member 3 is located away from the bottom of the first connecting member 2, and the slide column 31 is located in the lower slide groove 54. The support plate 4 is slowly opened, and the bottom of the second connecting member 3 slides in the lower slide groove 54. At the same time, the adjusting tooth 52 moves the block 9, so that the block 9 rotates and resets under the action of the second torsion spring 10. When resetting, it hits the next adjusting tooth 52. After the support plate 4 is adjusted to a suitable angle, the block 9 is stuck in a certain adjusting tooth 52, so that the bracket is completely opened. When the bracket needs to be closed, the angle of the support plate 4 is continued to be opened, so that the bottom of the second connecting member 3 is close to the guide plate 7. The guide plate 7 lifts the bottom of the second connecting member 3, so that the slide column 31 slides from the lower slide groove 54 to the upper slide groove 53. At this time, the block 9 is disengaged from the adjusting tooth 52, and the slide column 31 can slide quickly in the upper slide groove 53, so that the support plate 4 can be quickly closed.

[0032] The utility model provides an upper slide groove 53 and a lower slide groove 54 on both sides of the adjusting tooth set 5. When the support plate 4 is opened, the slide column 31 slides in the lower slide groove 54. The second connecting member 3 is pressed down by the first torsion spring 8, so that the clamping block 9 can just be clamped into the adjusting tooth 52. When the bracket needs to be closed, the slide column 31 slides into the upper slide groove 53 through the guide piece 7, and the clamping block 9 moves upward and disengages from the adjusting tooth 52, so that the support plate 4 can be quickly folded up. The bracket adopts an X-shaped structure, which is strong in load-bearing, stable, and beautiful as a whole.
