Description

Technical Field

[0001] This utility model relates to the field of furniture technology, specifically to a frame structure. Background Technology

[0002] In numerous fields such as furniture, equipment supports, and other applications requiring structural support, frame structures are widely used due to their advantages of sturdiness, durability, and high load-bearing capacity. Currently, the main method for enhancing stability by fixing the rear fork to the frame structure relies on screw assembly. Users typically need to manually install four screws to secure the fork. This assembly method is inconvenient; installing each screw requires time and effort, and tools are needed. For ordinary users, this process is cumbersome, easily leading to low assembly efficiency, and may even result in insecure screw installation affecting the stability of the rear fork, thus impacting the overall user experience. Utility Model Content

[0003] This utility model provides a frame structure to solve the problem of cumbersome stability enhancement in existing frame structures.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a frame structure, including a crossbeam, a vertical beam, and a reinforcing component. There are two vertical beams, which are respectively connected to the two ends of the crossbeam, and the crossbeam is perpendicular to the vertical beam. A circular limiting hole is formed on the vertical beam. A limiting groove is symmetrically formed near the two ends of the crossbeam. There are two reinforcing components, one end of each reinforcing component is inserted into one of the limiting grooves on the crossbeam, and the other end is inserted into the limiting hole on the vertical beam near the corresponding limiting groove.

[0005] The limiting groove includes a boss and two non-intersecting arc-shaped grooves. The centers of the two arc-shaped grooves are at different heights in the vertical direction. The boss is set between the two arc-shaped grooves so that the two arc-shaped grooves are connected by the boss. The boss protrudes towards the inside of the limiting groove. The angle α between the connecting line of the centers of the two arc-shaped grooves and the horizontal plane is 55°±5°. The diameters of the two arc-shaped grooves are the same, and a sliding groove is formed between the two arc-shaped grooves for the reinforcing component to swing around the limiting hole as the center.

[0006] Furthermore, the reinforcing component includes a first locking pin, a second locking pin, and a connector disposed between the first locking pin and the second locking pin. The first locking pin matches the shape of the limiting hole and is used to engage in the limiting hole. The second locking pin matches the shape of the arc-shaped groove and is used to engage in the limiting groove. When the first locking pin engages in the limiting hole and the second locking pin engages in the lower arc-shaped groove in the horizontal direction, the included angle b between the axis of the connector and the connecting line connecting the centers of the two arc-shaped grooves is 72°±5°.

[0007] Furthermore, the angle c between the axis of the first locking pin and the center line of the connector is 80°±5°.

[0008] Furthermore, the connector is a rod, and its two ends are bent to form a first locking pin and a second locking pin, respectively.

[0009] The beneficial effects of this utility model are as follows:

[0010] The frame structure provided by this utility model, through the setting of limiting grooves and limiting holes, allows the reinforcing components to be inserted into the frame structure, thereby increasing the stability of the frame structure, and by rotating the reinforcing components, the reinforcing components are fixed on the frame structure.

[0018] The specific embodiments of this application will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this application.

[0019] like Figure 1-5 As shown, this utility model embodiment provides a frame structure, including a crossbeam 1, a vertical beam 2, and a reinforcing component 3. There are two vertical beams 2, which are respectively connected to the two ends of the crossbeam 1, and the crossbeam 1 is perpendicular to the vertical beam 2. A circular limiting hole 21 is formed on the vertical beam 2. A limiting groove 11 is symmetrically formed near the two ends of the crossbeam 1. There are two reinforcing components 3. One end of each reinforcing component 3 is inserted into one of the limiting grooves 11 on the crossbeam 1, and the other end is inserted into the limiting hole 21 on the vertical beam 2 near the corresponding limiting groove 11.

[0020] The limiting groove 11 includes a boss 112 and two non-intersecting arc-shaped grooves 111. The centers of the two arc-shaped grooves 111 are at different heights in the vertical direction. The boss 112 is disposed between the two arc-shaped grooves 111, so that the two arc-shaped grooves 111 are connected by the boss 112. The boss 112 protrudes towards the inside of the limiting groove 11. The boss 112 is used to separate the two arc-shaped grooves 111 and prevent the reinforcing component 3 from falling out of the arc-shaped grooves 111. The angle α between the connecting line of the centers of the two arc-shaped grooves 111 and the horizontal plane is 55°±5°. The diameters of the two arc-shaped grooves 111 are the same, and a sliding groove 113 is formed between the two arc-shaped grooves 111 for the reinforcing component 3 to swing with the limiting hole 21 as the center.

[0021] The reinforcing component 3 includes a first locking pin 31, a second locking pin 32, and a connector 33 disposed between the first locking pin 31 and the second locking pin 32. The first locking pin 31 matches the shape of the limiting hole 21 and is used to engage in the limiting hole 21 to fix one end of the connector 33. The second locking pin 32 matches the shape of the arc groove 111 and is used to engage in the limiting groove 11 to fix the relative position of the end of the connector 33 away from the first locking pin 31 and the crossbeam 1. When the first locking pin 31 engages in the limiting hole 21 and the second locking pin 32 engages in the lower arc groove 111 in the horizontal direction, the included angle b between the axis of the connector 33 and the connecting line connecting the centers of the two arc grooves 111 is 72°±5°.

[0022] When installing the reinforcing component 3, the first locking pin 31 is inserted into the limiting hole 21, thereby fixing one end of the reinforcing component 3 to the vertical beam 2. The second locking pin 32 is first inserted into the higher arc groove 111 in the horizontal direction. The reinforcing component 3 rotates around the center of the limiting hole 21, so that the second locking pin 32 is inserted into another arc groove 111.

[0023] To further enhance the stability of the connection between the crossbeam 1 and the vertical beam 2, in a preferred embodiment of this utility model, the distance from the center of the lower arc groove 111 in the vertical direction to the center of the limiting hole 21 is greater than the length of the connector 33.

[0024] To prevent the first locking pin 31 from falling out of the limiting hole 21, in a preferred embodiment of this utility model, the included angle c between the axis of the first locking pin 31 and the center line of the connector 33 is 80°±5°.

[0025] In order to reduce the number of processes and lower production costs, in a preferred embodiment of this utility model, the connector 33 is a rod, and the two ends of the connector 33 are bent to form a first locking pin 31 and a second locking pin 32, respectively.

[0026] In summary, the frame structure, through the setting of the limiting groove 11 and the limiting hole 21, allows the reinforcing component 3 to be inserted into the frame structure, thereby increasing the stability of the frame structure, and by rotating the reinforcing component 3, the reinforcing component 3 is fixed on the frame structure.

[0027] The embodiments described above merely illustrate the implementation of this utility model, and should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
