Description

Technical Field

[0001] This utility model relates to the field of metal connectors, and in particular to a damping buffer type folding joint. Background Technology

[0002] Folding joints, as an important mechanical connection component, are widely used in many fields. They are mainly used to achieve a foldable connection between two components.

[0003] In existing applications of folding joints, some folding joints use a common hinge structure. By setting a certain friction pair at the pivot, the friction between metals is used to generate a damping effect, making the folding action relatively smoother.

[0004] The existing technology has the following drawbacks: In terms of damping adjustment, the damping force of methods that rely on ordinary hinge friction pairs to generate damping is often fixed and it is difficult to adjust flexibly according to actual use. It cannot meet the diverse needs for folding stability under different loads and usage frequencies. For example, when heavy objects are placed on the furniture before folding, the fixed damping force may not be able to ensure the smoothness of the movement and may easily cause impact. Therefore, a damping buffer type folding joint is proposed to solve the above problems. Summary of the Invention

[0005] To overcome the above shortcomings, this utility model provides a damping buffer type folding joint, which aims to improve the problem that the damping force cannot be adjusted in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a damping buffer type folding joint, including a connector, a circular tube penetrating the inner wall of the connector, a rectangular block fixedly connected to the top end of the circular tube, a fixing plate penetrating the outer wall of the rectangular block and the circular tube, a movable head fixedly connected to the front end of the fixing plate, an adjusting screw penetrating and rotatably connected to the inner wall of the circular tube, a slider threadedly connected to the outer wall of the adjusting screw, a pressing rod fixedly connected to the left side wall of the slider, a sliding rod fixedly connected to the outer wall of the pressing rod, a friction mechanism provided on the outer wall of the sliding rod, and a limit mechanism provided on the outer wall of the connector;

[0007] The friction mechanism includes a wedge block, which is slidably connected to the outer wall of the slide rod, and a contact plate is fixedly connected to the top of the wedge block.

[0008] As a further description of the above technical solution:

[0009] The limiting mechanism includes a support block, which is fixedly connected to the outer wall of the connector. A positioning screw is threaded through the inner wall of the support block. A rotating tube is rotatably connected to the right end of the positioning screw, and a blocking block is fixedly connected to the front end of the rotating tube.

[0010] As a further description of the above technical solution:

[0011] The shielding block is inserted into the outer wall of the circular tube.

[0012] As a further description of the above technical solution:

[0013] The rotating tube is slidably connected to the outer wall of the connector.

[0014] As a further description of the above technical solution:

[0015] The slider is slidably connected to the inner wall of the circular tube.

[0016] As a further description of the above technical solution:

[0017] The top of the contact plate contacts the inner wall of the connector.

[0018] As a further description of the above technical solution:

[0019] The contact plate is slidably connected to the inner wall of the circular tube.

[0020] As a further description of the above technical solution:

[0021] The rectangular block runs through the inner wall of the connector.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, the pressure between the contact plate and the inner wall of the connector is changed by rotating the adjusting screw to drive the relevant components to move. This achieves flexible adjustment of the damping force. Furthermore, the two sets of adjusting screws inside the round tube can further increase the friction force as needed, so that the folding or unfolding action can be carried out smoothly and controllably. This effectively avoids the impact caused by excessively fast action, improves the comfort of use and the stability of operation, and meets the diverse needs of different scenarios for damping effect.

[0024] 2. In this utility model, by using a limiting mechanism composed of a positioning screw, a rotating tube, and a blocking block, the components can be easily disassembled and installed by rotating the positioning screw in simple steps. The operation is convenient and facilitates subsequent maintenance work such as inspection and replacement of parts. This ensures that the overall structure can maintain good performance during long-term use, extends its service life, and improves the practicality and applicability of the structure.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Reference Figures 1-3This utility model provides an embodiment of a damping buffer type folding joint, including a connector 1, which and a movable head 5 form an integral foldable connector. A circular tube 3 penetrates the inner wall of the connector 1. A rectangular block 2 is fixedly connected to the top of the circular tube 3. The rectangular block 2 mainly connects to a fixing plate 4, allowing the circular tube 3 to rotate along with the fixing plate 4. The outer walls of the rectangular block 2 and the circular tube 3 are penetrated by the fixing plate 4. The fixing plate 4 has corresponding slots for the rectangular block 2 and the circular tube 3, which can satisfy... The round tube 3 and the rectangular block 2 pass through the slot here. The front end of the fixed plate 4 is fixedly connected to the movable head 5. The inner wall of the round tube 3 is rotatably connected to the adjusting screw 6. The outer wall of the adjusting screw 6 is threadedly connected to the slider 7. The middle part of the slider 7 is provided with a thread that matches the adjusting screw 6, so that the slider 7 can move along the outer wall of the adjusting screw 6. The left side wall of the slider 7 is fixedly connected to the extrusion rod 8. The outer wall of the extrusion rod 8 is fixedly connected to the slide rod 9. The outer wall of the slide rod 9 is provided with a friction mechanism. The outer wall of the connector 1 is provided with a limit mechanism.

[0035] The friction mechanism includes a wedge 10, which is slidably connected to the outer wall of the slide rod 9. The wedge 10 is triangular and has a slot, which allows the slide rod 9 to move along the slot. A contact plate 11 is fixedly connected to the top of the wedge 10. The surface of the contact plate 11 is made of rubber material, which can increase the friction with the inner wall of the connector 1.

[0036] Reference Figures 5-6 The limiting mechanism includes a support block 12, which is fixedly connected to the outer wall of the connector 1. A positioning screw 13 is threaded through and threaded onto the inner wall of the support block 12. The inner wall of the support block 12 has the same texture as the positioning screw 13, which allows the positioning screw 13 to move along the inner wall of the support block 12. A rotating tube 14 is rotatably connected to the right end of the positioning screw 13. A blocking block 15 is fixedly connected to the front end of the rotating tube 14. The blocking block 15 is inserted into the outer wall of the round tube 3. The round tube 3 has an annular opening, which allows the blocking block 15 to enter the opening and block the round tube 3. The rotating tube 14 is slidably connected to the outer wall of the connector 1. A slot is opened on the connector 1, which allows the rotating tube 14 to move back and forth along the slot.

[0037] Reference Figures 2-4 The slider 7 is slidably connected to the inner wall of the round tube 3. The top of the contact plate 11 is in contact with the inner wall of the connector 1. The contact plate 11 is slidably connected to the inner wall of the round tube 3. The rectangular block 2 passes through the inner wall of the connector 1. The connector 1 has a slot corresponding to the rectangular block 2, which can satisfy the subsequent rectangular block 2 to pass through the connector 1 and enter the slot of the fixing plate 4.

[0038] Working principle: When the connector 1 and the movable head 5 are in use, the movable head 5 folds or unfolds under force, and the fixed plate 4 drives the rectangular block 2 and the round tube 3 to rotate synchronously inside the connector 1, realizing the overall folding and unfolding function. If it is necessary to adjust its damping, simply rotate the adjusting screw 6, and the slider 7 connected to it will slide along the inner wall of the round tube 3, driving the pressing rod 8 and the sliding rod 9 to move synchronously. When the sliding rod 9 moves, it will press the wedge block 10 to move, so that the contact plate 11 contacts the inner wall of the connector 1. The surface of the contact plate 11 is made of rubber material. The greater the pressure, the greater the friction generated when the round tube 3 rotates, thereby realizing the adjustment of the damping force. Since there are two sets of adjusting screws 6 inside the round tube 3, the friction can be increased by rotating the other set of adjusting screws 6.

[0039] When it is necessary to separate the connector 1, fixing plate 4, round tube 3, and movable head 5, simply rotate the positioning screw 13 to move the rotating tube 14 and the blocking block 15, allowing the blocking block 15 and the opening of the round tube 3 to separate. Before disassembly, first rotate the fixing plate 4 and the movable head 5 to... Figure 1 Position the rectangular block 2 so that it aligns with the slot of the connector 1. Then pull out the round tube 3 to separate it from the inner wall slots of the rectangular block 2, connector 1, and fixing plate 4. During installation, first place the fixing plate 4 at the rotating opening of connector 1, then pass the round tube 3 and rectangular block 2 through the slots of connector 1 and fixing plate 4 in sequence, so that the rectangular block 2 is located on the inner wall of the slot of fixing plate 4. Finally, rotate the positioning screw 13 in the opposite direction so that the positioning screw 13 moves forward with the rotating tube 14 and the blocking block 15, so that the blocking block 15 is inserted into the opening of the round tube 3.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
