Description

Technical Field

[0001] This utility model relates to the field of furniture repair and reinforcement technology, specifically to a sofa and chair repair structure. Background Technology

[0002] A sofa is a multi-seat chair with cushions, usually with armrests on both sides and a thick back. It is designed to provide a comfortable sitting or reclining experience and is a very common type of furniture in modern homes. Most existing sofas use wooden frames, and after long-term use, the crossbeams and longitudinal beams of the frame are prone to deformation and damage. Therefore, they need to be repaired and reinforced to extend the service life of the sofa.

[0003] Existing methods typically involve placing wooden boards or other support plates on one side of the crossbeams and longitudinal beams and securing them with screws to achieve the purpose of repair and reinforcement. However, directly fixing the reinforcement to one side of the crossbeams and longitudinal beams results in an unsightly protruding part, and the protruding part may cause discomfort to the user when handling or using the equipment. If the reinforcement is placed at the same level as the crossbeams and longitudinal beams, it is necessary to cut both ends of the reinforcement to make it fit snugly between the crossbeams and longitudinal beams. However, this operation is cumbersome and inconvenient, making it difficult for workers to perform repairs and reinforcements at home.

[0004] In view of this, the present invention proposes a sofa and seat repair structure. Utility Model Content

[0026] The adjusting assembly 7 includes: a fixing ring 701 fixedly connected to one side of the connecting plate 6, with an elastic sheet 702 fixedly connected to the inner wall of the fixing ring 701 at equal angles; a clamping ring 704 rotatably connected to one end of the surface of the rotating rod 5, with a nut 703 fixedly connected to one end of the clamping ring 704; and an external thread 705 formed on one end of the surface of the rotating rod 5, with the external thread 705 and the inner wall of the nut 703 forming a threaded engagement structure.

[0027] In this embodiment, the nut 703 is loosened by using a wrench or other tools to move the clamping ring 704 until it is completely separated from the fixed ring 701. Then, the connecting plate 6 is rotated to change its tilt angle to a suitable position. Then, the nut 703 is rotated in the opposite direction to move the clamping ring 704 into the fixed ring 701, thereby achieving the limiting and fixing of the connecting plate 6 after rotation.

[0030] In a further preferred embodiment of this utility model, anti-slip textures 1 are provided at equal intervals on one end of the connecting plate 6, and the anti-slip textures 1 are arc-shaped.

[0031] In this embodiment, the arc-shaped anti-slip texture 1 is used to improve the anti-slip friction between the connecting plate 6 and the surfaces of the crossbeam and the vertical beam. Example 2

[0032] Based on Example 1, a preferred embodiment of the sofa and chair repair structure provided by this utility model is as follows: Figures 1 to 5 As shown: The lifting assembly 4 includes: a sliding groove 406 formed inside the second reinforcing plate 3, and a fixing groove 404 formed on the inner bottom wall of the sliding groove 406; a threaded rod 409 rotatably connected to the middle position of the inner wall of the sliding groove 406, and a rotating wheel 401 rotatably connected to the inner wall of the fixing groove 404, one end of the rotating wheel 401 being fixedly connected to one end of the threaded rod 409; a threaded plate 403 threadedly connected to the surface of the threaded rod 409, and two ends of one side of the threaded plate 403 being fixedly connected to a sliding rod 402, one end of the sliding rod 402 extending to the outside of the second reinforcing plate 3 and being fixedly connected to the first reinforcing plate 2; and the other end being fixedly connected.

[0033] In this embodiment, the rotating wheel 401 is turned to drive the threaded rod 409 to rotate, causing the threaded plate 403 to slide and drive the slide rod 402 to slide, thereby changing the distance between the first reinforcing plate 2 and the second reinforcing plate 3. Then, the locking bolt 405 is tightened to abut against the surface of the rotating wheel 401 to prevent the rotating wheel 401 from rotating accidentally, thereby changing the overall length of the first reinforcing plate 2 and the second reinforcing plate 3.

[0034] In a further preferred embodiment of the present invention, grooves are formed at equal angles on the surface of the rotating wheel 401, and the diameter of the cross-section of the rotating wheel 401 is greater than the thickness of the second reinforcing plate 3.

[0035] In this embodiment, a grooved rotating wheel 401 is used so that the user can manually rotate the rotating wheel 401.

[0036] In a further preferred embodiment of the present invention, the slide bar 402 is provided with scale values, and one end of the slide bar 402 is fixedly connected to the bottom end of the first reinforcing plate 2 by bolts.

[0037] In this embodiment, a slider 402 with graduated values ​​is used to clearly determine the sliding and lifting distance of the first reinforcing plate 2.

[0038] In a further preferred embodiment of the present invention, a locking bolt 405 is threadedly connected to the surface of the second reinforcing plate 3 on one side of the fixing groove 404. The locking bolt 405 can be used to lock the rotating wheel 401.

[0039] In a further preferred embodiment of the present invention, the inner wall of the sliding groove 406 is symmetrically provided with a sliding groove 408, and the two ends of the threaded plate 403 are fixedly connected with sliders 407 that slide and cooperate with the inside of the sliding groove 408.

[0040] In this embodiment, the sliding of the slider 407 inside the groove 408 is used to improve the smoothness of the sliding of the threaded plate 403.

[0041] The working principle of this utility model is as follows: First, loosen the locking bolt 405 using a screwdriver or other tools. Then, rotate the rotating wheel 401 to drive the threaded rod 409 to rotate. Utilizing the threaded engagement between the threaded rod 409 and the threaded plate 403, the threaded plate 403 slides, causing the sliding rod 402 to slide. This changes the distance between the first reinforcing plate 2 and the second reinforcing plate 3. Then, tighten the locking bolt 405 to press against the surface of the rotating wheel 401 to prevent accidental rotation of the rotating wheel 401. This changes the overall length of the first reinforcing plate 2 and the second reinforcing plate 3, allowing it to meet the repair and reinforcement needs of different frame beams and vertical beams.

[0042] Then, loosen the nut 703 with a wrench or other tools to move the clamping ring 704 until it is completely separated from the fixed ring 701. Then, rotate the connecting plate 6 to change its tilt angle to a suitable position, and then rotate the nut 703 in the opposite direction to move the clamping ring 704 into the fixed ring 701. The elastic plate 702 is used to improve the firmness of the clamping ring 704 and the inner wall of the fixed ring 701, so as to achieve the limiting and fixing after the connecting plate 6 is rotated.

[0043] Then it is snapped between the horizontal and vertical beams on the frame, and the connecting plate 6 can be locked and installed on the horizontal and vertical beams by external bolts to achieve the repair and reinforcement of the horizontal and vertical beams.

[0044] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
