Abstract
Description
Technical Field
[0001] This utility model relates to a damping buffer with gear adjustment function. Background Technology
[0002] A door and window damper is a mechanical device used to reduce the impact force when doors and windows close. Its main function is to slow down the closing speed of doors and windows, thereby reducing the impact force on the door and window frames and other parts, and extending the service life of the doors and windows. In addition, the damper also makes the closing of doors and windows smoother and reduces noise.
[0003] There is an existing one-way buffer for sliding doors with a damper and a tension spring. One end of the tension spring is fixed at a certain position, that is, the starting point of the tension spring is fixed. After assembly, it is not convenient to change the performance of the buffer by changing the performance of the tension spring. This makes it difficult to improve the applicability of the product and the market competitiveness of the product. If the performance of the tension spring needs to be changed, the housing needs to be disassembled and the tension spring needs to be reinstalled and fixed in another position or replaced with a tension spring with different parameters. This is cumbersome and it is necessary to solve this problem. Utility Model Content
[0004] This invention overcomes the shortcomings of the above-mentioned technologies and provides a damping buffer with gear adjustment function.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A damping buffer with gear adjustment function includes a base 1. One end of the base 1 is provided with a telescopic damper 2 and a gear adjustment block 3. The movable end of the telescopic damper 2 extends towards the other end of the base 1 and is connected to a movable latch 4. A tension spring 5 connects the gear adjustment block 3 and the movable latch 4. The base 1 is also provided with a first guide limiting channel 6 for guiding and limiting the movement of the movable latch 4 and a second guide limiting channel 6 for guiding and limiting the movement of the gear adjustment block 3. The first guide limiting channel 6, at the end away from the telescopic damper 2, has a bend 61 for the movable buckle 4 to be engaged when in position. The movable buckle 4 can be triggered to bend out from the bend 61 and disengage. The second guide limiting channel 7 has at least two limiting parts 71 that can limit the gear adjustment block 3 to prevent the gear adjustment block 3 from moving towards the other end of the seat 1. The gear adjustment block 3 can be manually switched between the limiting parts 71 to be limited.
[0007] Preferably, the gear adjustment block 3 and the tension spring 5 are located below the telescopic damper 2. The first guide limiting channel 6 has an upwardly opening first opening 60, through which the upper end of the movable buckle 4 is exposed upward. The second guide limiting channel 7 has a downwardly opening second opening 70, through which the lower end of the gear adjustment block 3 is exposed downward. The limiting part 71 is located at the second opening 70.
[0008] Preferably, the seat 1 includes a front half shell 11 and a rear half shell 12 connected together, the front half shell 11 and the rear half shell 12 extending to the left and right respectively, and the first opening 60 and the second opening 70 are respectively located at the junction of the front half shell 11 and the rear half shell 12.
[0009] Preferably, the front half-shell 11 and the rear half-shell 12 are connected and fixed by a plurality of front and rear screws 10.
[0010] Preferably, there are 2 to 4 limiting portions 71.
[0011] Compared with the prior art, the beneficial effects of this utility model are:
[0012] 1. The structure of this invention is simple and easy to implement. The setting of the gear adjustment block facilitates the connection of the starting end of the tension spring to it. Thus, by adjusting the position of the gear adjustment block, the position of the starting end of the tension spring can be changed, thereby adjusting the performance of the tension spring, which is practical. The setting of the limiting part of the second guide limiting channel facilitates the limiting of the gear adjustment block to prevent the gear adjustment block from moving towards the other end of the seat. By manually adjusting the position of the gear adjustment block between different limiting parts, the starting position of the tension spring can be limited. It is easy to adjust and has good practicality.
[0013] 2. The upward-opening design of the first opening in this case facilitates the placement of a trigger to activate the movable latch during use, making it suitable for certain applications. The downward-opening design of the second opening facilitates the downward exposure of the limiting part and the gear adjustment block through the second opening, enabling manual adjustment by the user and improving its practicality.

[0023] The following examples provide a more detailed description of the features and other related characteristics of this utility model, to facilitate understanding by those skilled in the art:
[0024] like Figures 1 to 8 As shown, a damping buffer with gear adjustment function includes a base 1. One end of the base 1 is provided with a telescopic damper 2 and a gear adjustment block 3. The movable end of the telescopic damper 2 extends towards the other end of the base 1 and is connected to a movable latch 4. A tension spring 5 connects the gear adjustment block 3 and the movable latch 4. The base 1 is also provided with a first guide limiting channel 6 for guiding and limiting the movement of the movable latch 4 and a second guide limiting channel 6 for guiding and limiting the movement of the gear adjustment block 3. The first guide limiting channel 6, at the end away from the telescopic damper 2, is provided with a bend 61 for the movable buckle 4 to be engaged when in position. The movable buckle 4 can be triggered to bend out from the bend 61 and disengage. The second guide limiting channel 7 is provided with at least two limiting parts 71 that can limit the gear adjustment block 3 to prevent the gear adjustment block 3 from moving towards the other end of the seat 1. The gear adjustment block 3 can be manually switched between the limiting parts 71.
[0025] The working principle of this case is as follows: Figure 3 or Figure 5 or Figure 7 As shown, the buffer is in the closed state, as... Figure 4 or Figure 6 As shown in Figure 8, the buffer is in the open state. In the open state, when the buffer moves to the right and the movable latch 4 is triggered to bend out from the bend 61 and disengage, the telescopic damper 2 gradually contracts and plays a buffering role.
[0026] As described above, the structure of this invention is simple and easy to implement. The gear adjustment block 3 is designed to allow the starting end of the tension spring 5 to be connected to it. Thus, by adjusting the position of the gear adjustment block 3, the starting position of the tension spring 5 can be changed, thereby adjusting the performance of the tension spring 5, which is practical. The limiting part 71 of the second guide limiting channel 7 is designed to limit the gear adjustment block 3 to prevent it from moving towards the other end of the seat 1. By manually adjusting the position of the gear adjustment block 3 between different limiting parts 71, the starting position of the tension spring 5 can be limited, which is convenient to adjust and practical.
[0027] like Figures 3 to 8 As shown, in specific implementation, the gear adjustment block 3 and the tension spring 5 are located below the telescopic damper 2, as follows. Figure 1 , Figure 2 As shown, the first guide limiting channel 6 has an upwardly opening first opening 60, through which the upper end of the movable buckle 4 is exposed upward. The second guide limiting channel 7 has a downwardly opening second opening 70, through which the lower end of the gear adjusting block 3 is exposed downward. The limiting part 71 is located at the second opening 70.
[0028] As described above, the upward opening of the first opening 60 in this case facilitates the placement of a trigger element above to activate the movable latch 4 during use, making it suitable for specific applications. The downward opening of the second opening 70 facilitates the downward display of the limiting part 71 and the gear adjustment block 3 through the second opening 70, enabling manual adjustment by the user and improving practicality.
[0029] As described above, in a specific implementation, the seat 1 includes a front half shell 11 and a rear half shell 12 connected together. The front half shell 11 and the rear half shell 12 extend to the left and right respectively. The first opening 60 and the second opening 70 are located at the junction of the front half shell 11 and the rear half shell 12 respectively, which is convenient to implement.
[0030] like Figure 1As shown, in a specific implementation, the front half-shell 11 and the rear half-shell 12 are connected and fixed by a number of front and rear screws 10, which makes assembly and disassembly convenient.
[0031] As described above, in specific implementations, there are 2 to 4 limiting parts 71.
[0032] As stated above, this case protects a damping buffer with gear adjustment function, and all technical solutions with the same or similar structure as this case should be considered to fall within the protection scope of this case.
