Description

Technical Field

[0001] This utility model relates to the field of furniture assembly technology, specifically to a locking clip for furniture assembly. Background Technology

[0002] Furniture refers to movable items used in living spaces, offices, commercial spaces, and other areas for people to sit, lie down, and place items. Furniture typically consists of tables, chairs, beds, cabinets, sofas, bookshelves, etc., and can be made from different materials such as wood, metal, plastic, and fabric.

[0003] Patent No. 202421186541.3 discloses a locking clip for furniture assembly. This device has a simple structure, strong practicality, and beautiful appearance, making it suitable for box-type substations.

[0004] However, existing locking clips for furniture assembly use a structure such as a sleeve, a pull rod, and a first bolt to adjust the angle of the first and second support plates. After the angle adjustment is completed, the pull rod is fixed by the first bolt entering the threaded hole on the pull rod, thus fixing the first and second support plates. However, there are gaps in the threaded holes on the pull rod. After the angle of the first and second support plates is adjusted, there are situations where there is no threaded hole at the position corresponding to the first bolt, making it impossible to fix the position of the pull rod. This has a certain impact on the efficiency and accuracy of the angle adjustment of the first and second support plates. Therefore, a locking clip for furniture assembly is designed. Utility Model Content

[0005] The main objective of this invention is to provide a locking mechanism for furniture assembly. This invention solves the problems of low efficiency and insufficient precision in angle adjustment of existing locking mechanisms for furniture assembly by setting a fixing component, gear, drive rod, tooth groove A, tooth groove B, rotating shaft B, support rod, bracket A, and bracket B.

[0006] The technical solution adopted by this utility model to solve its technical problem is a locking clip for furniture assembly, including a fixing frame. A drive rod is rotatably connected inside the fixing frame, and a transmission gear is sleeved on the outside of the drive rod. A bracket A is meshed with one side of the gear, and a toothed groove A is formed on the surface of bracket A to allow the gear to rotate on bracket A. A bracket B is meshed with the side of the gear away from bracket A, and a toothed groove B is formed on the surface of bracket B to allow the gear to rotate on bracket B. A fixing assembly for fixing the drive rod is provided outside the fixing frame. The part is welded with a support rod, and a rotating shaft B is provided on the inner side of the support rod. A fixed plate A and a fixed plate B are rotatably connected to the outside of the rotating shaft B. A connecting plate A is inserted into the inner side of the fixed plate A. A rotating shaft A is rotatably connected to one side of the connecting plate A, and a bracket A is rotatably connected to the outside of the rotating shaft A. A connecting plate B is inserted into the inner side of the fixed plate B, and a rotating shaft C is rotatably connected to the inner side of the connecting plate B. A bracket B is rotatably connected to the outside of the rotating shaft C. The connecting plate A, connecting plate B, fixed plate A, and fixed plate B are all screwed with clamps for connecting furniture parts.

[0007] By adopting the above technical solution, when the angles of fixed plate A and fixed plate B need to be adjusted, the drive rod inside the fixed frame drives the gear to rotate. Then, the gear drives bracket A and bracket B to move through tooth grooves A and B respectively. Then, bracket A pushes the connecting plate A on one side of the rotating shaft A to move. Connecting plate A drives fixed plate A to rotate through the rotating shaft B connected inside the support rod. At the same time, bracket B pushes the connecting plate B on one side of the rotating shaft C. Connecting plate B drives fixed plate B to rotate through the rotating shaft B, thereby facilitating the adjustment of the angles of fixed plate A and fixed plate B and improving the assembly efficiency of furniture.

[0008] Specifically, the fixing component includes a handle, a fixing sleeve, and a rubber pad. A handle that drives the drive rod to rotate is inserted into one side of the fixing frame, and a fixing sleeve that fixes the drive rod is threaded onto the outside of the handle.

[0009] By adopting the above technical solution, when the drive rod needs to be fixed, the fixing sleeve outside the handle is rotated, and then the fixing sleeve contacts the surface of the fixing frame. The two sides of the fixing sleeve extend outward and are square, increasing the contact area between the fixing sleeve and the fixing frame, so that the fixing sleeve limits the handle and prevents the handle from driving the drive rod to rotate, thereby facilitating the fixing of the drive rod.

[0010] The end of the drive rod connected to the fixed frame is fitted with a bearing through an interference fit, and the end of the drive rod connected to the handle is also fitted with a bearing through an interference fit, which makes the rotation of the drive rod stable.

[0011] Specifically, a rubber pad is adhered to one side of the fixing sleeve to increase friction with the fixing frame.

[0012] By adopting the above technical solution, when the fixing sleeve is connected to the fixing frame, the rubber pad on the fixing sleeve contacts the surface of the fixing frame, increasing the friction between the fixing sleeve and the fixing frame and improving the stability of the fixing sleeve in fixing the handle.

[0013] Specifically, threaded holes are provided on the surfaces of both connecting plate A and connecting plate B, and screws that enter the threaded holes are threaded to the outside of both fixing plate A and fixing plate B.

[0014] By adopting the above technical solution, when adjusting the length of connecting plate A and connecting plate B, the screws connected to the external threads of fixing plate A and fixing plate B are rotated respectively, so that the screws move out of connecting plate A and connecting plate B respectively. Then, connecting plate A and connecting plate B are pulled to move, so that connecting plate A moves within fixing plate A and connecting plate B moves within fixing plate B. After the adjustment is completed, the screws on fixing plate A and fixing plate B are rotated respectively, so that the screws enter the threaded holes opened on connecting plate A and connecting plate B respectively. There are several threaded holes in each case, so that connecting plate A and connecting plate B are fixed, thereby facilitating the adjustment of the length of connecting plate A and connecting plate B.

[0015] Specifically, both bracket A and bracket B have limit blocks welded to their exteriors, and the inner side of the fixing frame has symmetrical limit grooves that allow the limit blocks to slide.

[0016] By adopting the above technical solution, when bracket A and bracket B move within the fixed frame, the limiting blocks welded to the outside of bracket A and bracket B slide within the symmetrically opened limiting grooves inside the fixed frame, thereby improving the stability of the movement of bracket A and bracket B.

[0017] The beneficial effects of this utility model are:

[0018] (1) The locking clip for furniture assembly described in this utility model allows for the adjustment of the angles of fixed plate A and fixed plate B by rotating the handle outside the fixed frame. The handle then drives the gear connected to the screw on the drive rod to rotate. The gear then drives bracket A and bracket B to move through tooth groove A and tooth groove B respectively. Then bracket A pushes the connecting plate A on one side of the rotating shaft A to move. The connecting plate A drives the fixed plate A to rotate through the rotating shaft B connected inside the support rod. At the same time, bracket B pushes the connecting plate B on one side of the rotating shaft C. The connecting plate B drives the fixed plate B to rotate through the rotating shaft B, thereby facilitating the adjustment of the angles of fixed plate A and fixed plate B and improving the assembly efficiency of furniture.

[0019] (2) The locking clip for furniture assembly described in this utility model, when the drive rod is to be fixed, rotate the fixing sleeve outside the handle, and then the fixing sleeve contacts the surface of the fixing frame. The two sides of the fixing sleeve extend outward and are square, increasing the contact surface between the fixing sleeve and the fixing frame. Then the rubber pad on the fixing sleeve contacts the surface of the fixing frame, increasing the friction between the fixing sleeve and the fixing frame, so that the fixing sleeve limits the handle and prevents the handle from driving the drive rod to rotate, thereby facilitating the fixing of the drive rod.

[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0026] To improve furniture assembly efficiency, as one embodiment of this utility model, such as Figure 1 , Figure 2 and Figure 3As shown, the present invention discloses a locking clip for furniture assembly, comprising a fixing frame 1. A drive rod 19 is rotatably connected inside the fixing frame 1, and a transmission gear 18 is sleeved on the outside of the drive rod 19. A bracket A3 is meshed with one side of the gear 18, and a toothed groove A16 is formed on the surface of the bracket A3 to allow the gear 18 to rotate on the bracket A3. A bracket B13 is meshed with the side of the gear 18 away from the bracket A3, and a toothed groove B17 is formed on the surface of the bracket B13 to allow the gear 18 to rotate on the bracket B13. A fixing assembly 21 for fixing the drive rod 19 is provided outside the fixing frame 1. The fixing frame 1 is welded with... A support rod 15 is provided, and a rotating shaft B8 is provided on the inner side of the support rod 15. A fixing plate A7 and a fixing plate B14 are rotatably connected to the outside of the rotating shaft B8. A connecting plate A4 is inserted into the inner side of the fixing plate A7. A rotating shaft A2 is rotatably connected to one side of the connecting plate A4, and a bracket A3 is rotatably connected to the outside of the rotating shaft A2. A connecting plate B11 is inserted into the inner side of the fixing plate B14, and a rotating shaft C12 is rotatably connected to the inner side of the connecting plate B11. A bracket B13 is rotatably connected to the outside of the rotating shaft C12. Furniture parts connecting clips 20 are screwed to the outside of the connecting plate A4, connecting plate B11, fixing plate A7, and fixing plate B14.

[0027] In use, when the angles of fixed plates A7 and B14 need to be adjusted, the drive rod 19 inside the fixing frame 1 drives the gear 18 to rotate. Then, the gear 18 drives the bracket A3 and bracket B13 to move through the tooth grooves A16 and B17 respectively. Then, the bracket A3 pushes the connecting plate A4 on one side of the rotating shaft A2 to move. The connecting plate A4 drives the fixed plate A7 to rotate through the rotating shaft B8 connected inside the support rod 15. At the same time, the bracket B13 pushes the connecting plate B11 on one side of the rotating shaft C12. The connecting plate B11 drives the fixed plate B14 to rotate through the rotating shaft B8, thereby facilitating the adjustment of the angles of fixed plates A7 and B14 and improving the assembly efficiency of the furniture.

[0028] To secure the drive rod 19, for example, such as Figure 3 As shown, the present invention also includes the fixing component 21, which includes a handle 22, a fixing sleeve 23 and a rubber pad 24. The handle 22, which drives the drive rod 19 to rotate, is inserted into one side of the fixing frame 1. The fixing sleeve 23, which fixes the drive rod 19, is externally threaded to the handle 22.

[0029] When using the drive rod 19, rotate the fixing sleeve 23 outside the handle 22. Then the fixing sleeve 23 contacts the surface of the fixing frame 1. The fixing sleeve 23 extends outward on both sides and is square, increasing the contact area between the fixing sleeve 23 and the fixing frame 1. This allows the fixing sleeve 23 to limit the handle 22 and prevent the handle 22 from driving the drive rod 19 to rotate, thus facilitating the fixing of the drive rod 19.

[0030] To improve the stability of the retaining sleeve 23 in securing the grip 22, for example, such as Figure 3 As shown, the present invention also includes a rubber pad 24 for increasing friction with the fixing frame 1, which is adhered to one side of the fixing sleeve 23.

[0031] When in use, when the fixing sleeve 23 is connected to the fixing frame 1, the rubber pad 24 on the fixing sleeve 23 contacts the surface of the fixing frame 1, increasing the friction between the fixing sleeve 23 and the fixing frame 1, and improving the stability of the fixing sleeve 23 in fixing the handle 22.

[0032] To adjust the lengths of connecting plate A4 and connecting plate B11, for example, as follows: Figure 1 As shown, the present invention also includes threaded holes 5 on the surfaces of the connecting plate A4 and the connecting plate B11, and screws 6 that enter the threaded holes 5 are threadedly connected to the outside of the fixing plate A7 and the fixing plate B14.

[0033] When adjusting the lengths of connecting plates A4 and B11, rotate the threaded screws 6 on the external threads of fixing plates A7 and B14 respectively, causing the screws 6 to move out of the connecting plates A4 and B11 respectively. Then, pull the connecting plates A4 and B11 to move, so that connecting plate A4 moves within fixing plate A7 and connecting plate B11 moves within fixing plate B14. After adjustment, rotate the screws 6 on fixing plates A7 and B14 respectively, so that the screws 6 enter the threaded holes 5 on connecting plates A4 and B11 respectively. There are several threaded holes 5, which fix the connecting plates A4 and B11, thus facilitating the adjustment of the lengths of connecting plates A4 and B11.

[0034] To improve the stability of the movement of bracket A3 and bracket B13, for example, as follows: Figure 2 As shown, the present invention also includes limiting blocks 10 welded to the outside of both bracket A3 and bracket B13, and limiting grooves 9 symmetrically opened on the inner side of the fixing frame 1 to allow the limiting blocks 10 to slide.

[0035] When in use, as bracket A3 and bracket B13 move within the fixed frame 1, the limiting blocks 10 welded to the outside of bracket A3 and bracket B13 slide within the limiting grooves 9 symmetrically opened within the fixed frame 1, thereby improving the stability of the movement of bracket A3 and bracket B13.

[0036] When this utility model is in use, if the angle of the fixed plate A7 and the fixed plate B14 needs to be adjusted, the drive rod 19 in the fixed frame 1 drives the gear 18 to rotate. Then, the gear 18 drives the bracket A3 and the bracket B13 to move through the tooth groove A16 and the tooth groove B17 respectively. Then, the bracket A3 pushes the connecting plate A4 on one side of the rotating shaft A2 to move. The connecting plate A4 drives the fixed plate A7 to rotate through the rotating shaft B8 connected in the support rod 15. At the same time, the bracket B13 pushes the connecting plate B11 on one side of the rotating shaft C12. The connecting plate B11 drives the fixed plate B14 to rotate through the rotating shaft B8, thereby facilitating the adjustment of the angle of the fixed plate A7 and the fixed plate B14 and improving the assembly efficiency of the furniture.

[0037] When it is necessary to fix the drive rod 19, rotate the fixing sleeve 23 outside the handle 22. Then the fixing sleeve 23 contacts the surface of the fixing frame 1. The two sides of the fixing sleeve 23 extend outward and are square, increasing the contact surface between the fixing sleeve 23 and the fixing frame 1. This allows the fixing sleeve 23 to limit the handle 22 and prevent the handle 22 from driving the drive rod 19 to rotate, thus facilitating the fixing of the drive rod 19.

[0038] When the fixing sleeve 23 is connected to the fixing frame 1, the rubber pad 24 on the fixing sleeve 23 contacts the surface of the fixing frame 1, increasing the friction between the fixing sleeve 23 and the fixing frame 1, and improving the stability of the fixing sleeve 23 in fixing the handle 22.

[0039] When adjusting the length of connecting plate A4 and connecting plate B11, rotate the screws 6 connected to the external threads of fixing plate A7 and fixing plate B14 respectively, so that the screws 6 move out of the connecting plate A4 and connecting plate B11 respectively. Then pull the connecting plate A4 and connecting plate B11 to move, so that the connecting plate A4 moves in the fixing plate A7 and the connecting plate B11 moves in the fixing plate B14. After the adjustment is completed, rotate the screws 6 on fixing plate A7 and fixing plate B14 respectively, so that the screws 6 enter the threaded holes 5 opened on the connecting plate A4 and connecting plate B11 respectively. There are several threaded holes 5, so that the connecting plate A4 and connecting plate B11 are fixed, thereby facilitating the adjustment of the length of the connecting plate A4 and connecting plate B11.

[0040] When brackets A3 and B13 move within the fixed frame 1, the limiting blocks 10 welded to the outside of brackets A3 and B13 slide within the limiting grooves 9 symmetrically opened within the fixed frame 1, thereby improving the stability of the movement of brackets A3 and B13.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The descriptions of the above embodiments and specifications are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of protection claimed by this utility model.
