Abstract
Description
Technical Field
[0001] This utility model relates to the field of hinge technology, and in particular to an adjustable damping hinge. Background Technology
[0002] In the furniture industry, hinges are commonly used to connect cabinet doors to the cabinet body for easy opening and closing. Springs are typically incorporated into the hinges to provide a clamping force when the doors open and close. However, in practical use, the following problems have been found with existing technology: due to the springs, the door may collide with the cabinet body when closed due to the spring's rebound force, potentially damaging the door. Once the hinges are installed on the cabinet body, their position on the door is essentially fixed. Even slight deviations in the installation positions of the cabinet body and door prevent adjustment of their relative positions. Therefore, hinges with three-dimensional adjustment capabilities have emerged. These hinges allow for adjustment of the relative position between the door and cabinet body through three-dimensional adjustment. However, currently available hinges with three-dimensional adjustment typically use eccentric pins for adjustment. After prolonged use, these eccentric pins may slip and fail to achieve the correct adjustment, thus affecting the three-dimensional adjustment effect.
[0003] The technical problem to be solved by this application is: to design an adjustable damping hinge that can be stably adjusted. Utility Model Content
[0004] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide an adjustable damping hinge that can be stably adjusted.
[0005] The technical solution adopted by this utility model is as follows: an adjustable damping hinge, including a mounting base and a hinge seat hinged to the mounting base, the hinge seat is provided with an adjustment plate that limits and cooperates with it, the adjustment plate is provided with an adjustment screw that limits and drives with it, the adjustment plate is provided with a plurality of protrusions, the adjustment screw is provided with a spiral involute block, and the spiral involute block and the protrusion are in a limiting and driving cooperation.
[0006] In some embodiments, the hinge seat is provided with a mounting slot, and the adjusting plate is provided with a mounting block, with the mounting block and the mounting slot engaging in a locking fit.
[0007] In some embodiments, a connecting rod assembly that is hinged to each other is provided between the mounting base and the hinge base.
[0008] In some embodiments, the hinge seat contains a spring assembly that engages with the linkage assembly in a transmission manner.
[0009] In some embodiments, the hinge seat is provided with a mounting shell on the outside, and the hinge seat and the mounting shell are slidably engaged.
[0010] In some implementations, the adjusting screw and the mounting housing are in a limiting rotational engagement.
[0011] In some embodiments, the bumps are arranged along the length of the adjusting plate, and each bump is crescent-shaped.
[0012] In some embodiments, the hinge seat is further provided with a damping component that engages with the linkage assembly in a transmission manner.
[0013] This invention has the following technical effects: An adjusting plate with a limiting engagement is provided on the hinge seat. The adjusting plate has an adjusting screw with a limiting transmission engagement. The adjusting plate has several protrusions, and the adjusting screw has a spiral involute block. The spiral involute block and the protrusions have a limiting transmission engagement. By rotating the adjusting screw, the spiral involute block gradually engages with or separates from each protrusion, thereby generating a pushing force on the protrusions. This, in turn, generates a pushing force on the adjusting plate, thus driving the hinge seat to move and adjust. Because the spiral involute block gradually limits each protrusion to achieve displacement adjustment of the hinge seat, and because limiting the protrusions with the spiral involute block is equivalent to locking the protrusions, slippage is prevented, thus achieving a stable adjustment effect for the hinge seat.

[0020] 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.
[0021] Please see Figure 1-5 This utility model provides a technical solution: an adjustable damping hinge, including a mounting base 1 and a hinge seat 2 hinged to the mounting base 1. The mounting base 1 and the hinge seat 2 are connected by a connecting rod assembly 5 that is hinged to each other. The hinge seat 2 is provided with a mounting shell 7 on its exterior, wherein the hinge seat 2 and the mounting shell 7 are in sliding fit. An adjusting plate 3 is provided on the hinge seat 2 and is in limiting fit with it. The adjusting plate 3 is provided with an adjusting screw 4 in limiting and transmission fit with it. The adjusting plate 3 is provided with a mounting block 31. The hinge seat 2 is provided with a mounting slot 20 corresponding to the mounting block 31. The mounting block 31 and the mounting slot 20 are locked together. The adjustment plate 3 can be installed on the hinge seat 2 by fitting together. Several protrusions 30 are provided on the adjustment plate 3, arranged along the length of the adjustment plate 3, and each protrusion 30 is crescent-shaped. A spiral involute block 40 is provided at the lower end of the adjustment screw 4. The horizontal cross-section of the spiral involute block 40 is spiral-shaped. Because the spiral involute block 40 has an open end, when the adjustment screw 4 rotates, the protrusion 30 can enter the middle of the spiral involute block 40 along the open end. When the spiral involute block 40 takes the protrusion 30 from the open end, a pushing force is generated. The protrusion 30 is pushed backward along the edge of the spiral involute block 40. This pushing force acts on the adjusting plate 3. Since the adjusting plate 3 is mounted on the hinge seat 2, the pushing force generated by the spiral involute block 40 will push the hinge seat 2 to move within the mounting housing 7. When a protrusion 30 is engaged by the spiral involute block 40, as the adjusting screw 4 continues to rotate, the open end of the spiral involute block 40 will rotate forward, thereby engaging the next protrusion 30 and generating a continuous pushing force on the adjusting plate 3, thus achieving the adjustment of the lateral displacement of the hinge seat 2. When the hinge seat 2 needs to be adjusted in the opposite direction, simply rotate the adjusting screw 4 in the opposite direction to make the protrusion 30 exit along the open end of the spiral involute block 40. Since the cylindrical part of the adjusting screw 4 is in a limiting rotational fit with the corresponding hole on the mounting shell 7, the mounting position of the adjusting screw 4 relative to the mounting shell 7 does not change when the protrusion 30 exits from the open end of the spiral involute block 40. Therefore, it is equivalent to changing the horizontal lateral position of the protrusion 30, which is equivalent to changing the horizontal lateral position of the adjusting plate 3, thereby realizing the reverse displacement adjustment of the hinge seat 2 within the mounting shell 7.
[0022] In order to achieve a buffering effect when the hinge is opening and closing the door, the hinge base 2 is provided with a spring assembly 6 that is in transmission cooperation with the linkage assembly 5. In addition, the hinge base 2 is also provided with a damping assembly 8 that is in transmission cooperation with the linkage assembly 5.
[0023] The working principle of this utility model is as follows: An adjusting plate 3 is provided on the hinge seat 2, which is matched with a limiting mechanism. The adjusting plate 3 is provided with an adjusting screw 4, which is matched with a limiting transmission mechanism. The adjusting plate 3 is provided with several protrusions 30, and the adjusting screw 4 is provided with a spiral involute block 40. The spiral involute block 40 and the protrusions 30 are matched with a limiting transmission mechanism. By rotating the adjusting screw 4, the spiral involute block 40 gradually creates a limiting mechanism with each protrusion 30 or gradually separates from each limited protrusion 30. This causes the spiral involute block 40 to generate a pushing force on the protrusions 30, which in turn generates a pushing force on the adjusting plate 3. This allows the hinge seat 2 to be driven to move and be adjusted. Since the spiral involute block 40 gradually limits each protrusion 30 to achieve the displacement adjustment of the hinge seat 2, and the limiting mechanism of the spiral involute block 40 on the protrusions 30 is equivalent to limiting and locking the protrusions 30, there will be no slippage. This achieves the effect of stable adjustment of the hinge seat 2.
[0024] Finally, it should be noted that the above description is merely 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
