Referring to fig. 1 to 4, a damper provided in an embodiment of the present application includes a housing 10, a damping member 20, and an adjustment member 30.

The buffer assembly 20 is disposed in the housing 10, the buffer assembly 20 includes a damping cylinder 21 and an elastic member 22 both extending along a first direction (i.e., x direction in fig. 2), the damping cylinder 21 includes a cylinder body 211 and a piston rod 212 movably disposed in the cylinder body 211 along the first direction, the elastic member 22 has a first end 221 and a second end 222 disposed opposite to each other along the first direction, and the first end 221 of the elastic member 22 is connected to an end of the piston rod 212 protruding out of the cylinder body 211. The adjusting assembly 30 is disposed in the housing 10, the adjusting assembly 30 includes a first adjusting block 31 and an adjusting arm 32, the first adjusting block 31 is disposed at the second end 222 of the elastic member 22, the adjusting arm 32 is connected to the first adjusting block 31, and the adjusting arm 32 is configured to rotate around a first axis a perpendicular to the first direction relative to the housing 10, so as to drive the first adjusting block 31 to move along the first direction relative to the housing 10.

In the damper, the damping assembly 20 is arranged to include the damping cylinder 21 and the elastic member 22, the damping cylinder 21 includes the cylinder body 211 and the piston rod 212 movably disposed in the cylinder body 211, the first end 221 of the elastic member 22 is connected to one end of the piston rod 212 protruding out of the cylinder body 211, and since the extending direction of the elastic member 22 and the moving direction of the piston rod 212 are both parallel to the first direction, the elastic member 22 can provide an elastic force that makes the piston rod 212 have a tendency of moving toward one side close to the cylinder body 211 along the first direction. The damping cylinder 21 is provided to damp the elastic force of the elastic member 22 acting on the piston rod 212, thereby providing a damping force to the door leaf to gradually close the door leaf. By providing the adjustment assembly 30, the adjustment assembly 30 includes a first adjustment block 31 disposed at the second end 222 of the elastic member 22, and an adjustment arm 32 connected to the first adjustment block 31, wherein the adjustment arm 32 is configured to rotate around the first axis a relative to the housing 10 to drive the first adjustment block 31 to move relative to the housing 10 along the first direction, so that the first end 221 of the elastic member 22 moves along with the first adjustment block 31 relative to the housing 10 along the first direction to increase or decrease the distance between the first end 221 and the second end 222 of the elastic member 22. Consequently, through adjustment adjusting part 30, can change the distance between elastic component 22 both ends, can change the deformation volume of elastic component 22 promptly, make elastic component 22 act on the elasticity of piston rod 212 can increase or reduce to the speed and the dynamics homoenergetic that make the door leaf close can change, with the weight that is adapted to the door leaf, avoid the speed and the dynamics of door leaf closure too big or undersize, influence to use experience and buffering effect.

Specifically, second end 222 of resilient member 22 is disposed proximate to barrel 211 such that resilient member 22 is capable of providing a spring force that tends to move piston rod 212 in a first direction into barrel 211. For example, the damper has a first state and a second state, respectively, as shown in fig. 1-2, when the damper is in the first state, the second end 222 of the elastic member 22 is spaced from the first end 221 by a first predetermined distance, and as shown in fig. 3-4, when the damper is in the second state, the second end 222 of the elastic member 22 is spaced from the first end 221 by a second predetermined distance. The second preset distance is larger than the first preset distance. In this way, when the damper is in the first state, the amount of deformation of the elastic member 22 is small, and the elastic force of the elastic member 22 acting on the piston rod 212 is small, so that the damping force provided by the damper to the door to close the door is small, and the force to close the door is small, and the closing speed of the door is slow, and the damper is suitable for the door with small weight. When the buffer is in the second state, the deformation amount of the elastic member 22 is large, and the elastic force of the elastic member 22 acting on the piston rod 212 is large, so that the buffer provides a large buffering force for the door leaf to close the door leaf, the closing force of the door leaf is increased, the closing speed is increased, and the buffer is suitable for the door leaf with large weight.

It will be appreciated that the first and second states of the buffer are for illustrative purposes only and that the buffer is not limited to only two states but may have any state in which it gradually transitions from the first state to the second state or vice versa. That is, the second end 222 of the elastic member 22 can be located at any position on the moving path thereof along the first direction, thereby making the buffer highly adaptable to door leaves of different weights.

Fig. 5 is an exploded view of the adjustment assembly 30 of the embodiment of fig. 1.

In some embodiments, as shown in fig. 5, the first adjusting block 31 has an adjusting groove 311 along a first side in a second direction (i.e., a y direction in fig. 2) perpendicular to the first direction and the first axis a, respectively, and the adjusting groove 311 extends along the first direction. The adjusting arm 32 includes a rotating portion 320 spaced apart from the first side of the first adjusting block 31, and a first arm 321 having one end connected to the rotating portion 320, the rotating portion 320 is rotatably connected to the housing 10 around the first axis a, and one end of the first arm 321 away from the rotating portion 320 abuts against a groove wall of the adjusting groove 311 away from the elastic member 22 along the first direction, so that the first arm 321 can drive the first adjusting block 31 to move relative to the housing 10 along the first direction. In this way, by providing the adjusting arm 32 including the rotating portion 320 and the first arm 321 with one end connected to the rotating portion 320, the rotating portion 320 is rotatably connected to the housing 10 around the first axis a, so as to drive the first arm 321 to rotate around the first axis a relative to the housing 10. The first side of the adjusting block, which is spaced from the rotating part 320, is provided with an adjusting groove 311, so that one end of the first support arm 321, which is far away from the rotating part 320, can extend into the adjusting groove 311. Because the elastic force of the elastic element 22 makes the first adjusting block 31 have a movement tendency approaching to the second end 222 of the elastic element 22 along the first direction, the groove wall of the adjusting groove 311 away from the elastic element 22 along the first direction can abut against the first support arm 321, so that when the first support arm 321 rotates relative to the housing 10, the first support arm 321 can drive the first adjusting block 31 to move relative to the housing 10 along the first direction, thereby adjusting the position of the second end 222 of the elastic element 22 relative to the housing 10.

Alternatively, as shown in fig. 2 and fig. 4 to 5, the inner wall of the housing 10 is provided with a column 101 extending along a direction parallel to the first axis a, and the rotating portion 320 is sleeved outside the column 101 and rotatably connected to the column 101, so that the adjusting arm 32 is rotatably connected to the housing 10 around the first axis a by means of the column 101.

To facilitate the rotation of the rotating part 320 relative to the housing 10 about the first axis a, in some embodiments, the adjusting arm 32 further includes a second arm 322 disposed at an angle to the first arm 321 and intersecting the first arm 321 at the rotating part 320. The adjusting assembly 30 further includes a second adjusting block 34, the second adjusting block 34 is connected to an end of the second arm 322 away from the rotating portion 320, and the second adjusting block 34 is configured to be capable of moving relative to the housing 10 in a second direction to rotate the rotating portion 320 relative to the housing 10 about the first axis a by means of the second arm 322. Thus, by arranging the adjusting arm 32 further including the second arm 322 and the second adjusting block 34 connected to the end of the second arm 322 far from the rotating part 320, the second adjusting block 34 can move along the second direction relative to the housing 10 by operating the second adjusting block 34, so that the second adjusting block 34 drives the end of the second arm 322 connected thereto to move along the second direction relative to the housing 10, and the second arm 322 drives the rotating part 320 to rotate around the first axis a relative to the housing 10. Adjustment of the position of second end 222 of resilient member 22 relative to housing 10 is facilitated by the provision of second arm 322 and second adjustment block 34, since the operation of translating the part is more convenient than the operation of rotating the part and the translation of the part is easier to direct.

Specifically, as shown in fig. 2 and fig. 4-5, an end of the second arm 322 away from the rotating portion 320 is provided with a connecting hole 3221 penetrating through the second arm 322 along a third direction (i.e., a z direction in fig. 2) parallel to the first axis a, and the connecting hole 3221 extends along a direction perpendicular to the third direction. The second adjusting block 34 is provided with a connecting column 341 penetrating the connecting hole 3221 along the third direction, and the connecting column 341 is configured to move relative to the second support arm 322 along the extending direction of the connecting hole 3221. Thus, the second support arm 322 is provided with the connecting hole 3221, and the second adjusting block 34 is provided with the connecting column 341 penetrating through the connecting hole 3221, so that one end of the second support arm 322 far away from the rotating part 320 is movably connected with the second adjusting block 34, so that the second adjusting block 34 can drive the second support arm 322 to rotate, and the second support arm 322 can rotate relative to the housing 10 within a certain angle range.

In some embodiments, as shown in fig. 5, one side of the housing 10 in the direction parallel to the first axis a has a first wall surface 102 opposite to the second adjusting block 34, and the first wall surface 102 is provided with a sliding groove 103 extending in the second direction. A sliding portion 342 is convexly disposed on a side of the second adjusting block 34 facing the first wall surface 102, and the sliding portion 342 is slidably connected in the sliding slot 103 along the second direction. In this way, the second adjusting block 34 is slidably connected to the housing 10 by the sliding portion 342, and the sliding groove 103 provides a guiding function for the sliding of the second adjusting block 34, so that the movement of the second adjusting block 34 relative to the housing 10 along the second direction is more stable and smooth.

In order to enable the second adjusting block 34 to move along the second direction relative to the housing 10, in some embodiments, as shown in fig. 2 and fig. 4-5, the adjusting assembly 30 further includes a screw 35 passing through the second adjusting block 34 along the second direction, the screw 35 is in threaded connection with the second adjusting block 34, and the screw 35 is configured to rotate around its axis relative to the housing 10 to drive the second adjusting block 34 to move along the second direction relative to the housing 10. In this way, the screw 35 is disposed through the second adjusting block 34 along the second direction and is in threaded connection with the second adjusting block 34, so that the screw 35 can be screwed around the axis of the screw 35 to enable the second adjusting block 34 to have a displacement relative to the screw 35 along the second direction, and when the screw 35 is not screwed, the second adjusting block 34 is fixed relative to the screw 35, so that the elastic member 22 has an elastic force with a preset magnitude corresponding to the position of the elastic member relative to the housing 10.

In order to facilitate the operation of the bolt to rotate around its own axis relative to the housing 10, in some embodiments, as shown in fig. 5, one end of the screw 35 has an operation surface 351, the operation surface 351 is rotatably connected to an inner wall of one side of the housing 10 in the second direction, the inner wall of one side of the housing 10 connected to the operation surface 351 is provided with a first through hole 104 formed to penetrate along the second direction, and the first through hole 104 is coaxially arranged with the screw 35. In this way, a tool for screwing the screw 35, such as a wrench, can be connected to the operation surface 351 of the screw 35 through the first through hole 104, so as to screw the screw 35, and the adjustment operation can be performed from the outside of the housing 10 without disassembling the housing 10, so that the operation is simple.

In some embodiments, as shown in fig. 2 and 5, second end 222 of elastic member 22 is provided with a joint 223, and elastic member 22 is coupled to first adjustment block 31 by means of joint 223. The housing 10 is provided with a first limiting rib 105 on a moving path of the first adjusting block 31 along the first direction, and the first limiting rib 105 is configured to be capable of abutting against a side of the first adjusting block 31 close to the elastic member 22 along the first direction so as to limit the movement of the first adjusting block 31 towards the side close to the elastic member 22 along the first direction. In this way, it can be avoided that the second end 222 of the elastic member 22 retracts toward the first end 221 due to the failure or damage of the connection between the adjustment arm 32 and the first adjustment block 31, so that the damper fails.

Alternatively, the number of the first stopper ribs 105 is two, and the two first stopper ribs 105 are spaced apart from and disposed opposite to each other in the second direction.

In some embodiments, as shown in fig. 4 and 5, the inner wall of the housing 10 is provided with a second limiting rib 106 on the moving path of the first adjusting block 31 along the first direction, and the second limiting rib 106 is configured to be capable of abutting against a side of the first adjusting block 31 away from the elastic member 22 along the first direction so as to limit the movement of the first adjusting block 31 towards the side away from the elastic member 22 along the first direction. Therefore, the moving range of the first adjustment is limited, and the damage of parts caused by larger acting force among the parts due to overlarge adjustment amplitude is avoided.

All possible combinations of the technical features of the above embodiments may not be described for the sake of brevity, but should be considered as within the scope of the present disclosure as long as there is no contradiction between the combinations of the technical features.

The above-mentioned embodiments only express several embodiments of the present application, and the description thereof is more specific and detailed, but not construed as limiting the scope of the utility model. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the concept of the present application, which falls within the scope of protection of the present application.
