Abstract
Description
Technical Field
[0001] This utility model relates to the field of buffer technology for sliding doors, and in particular to a buffer that can recover its buffer state. Background Technology
[0002] In existing sliding door systems, buffers are usually installed in the track. The buffers provide cushioning force when the door closes, preventing the door from colliding violently with the door frame and extending the door's lifespan.
[0003] like Figure 1 As shown, this is a common buffer structure in the prior art. The buffer body 100 is provided with hooks, including a first buffer hook 200 and a second buffer hook 300. When the entire buffer is in a buffering state, the hooks are tilted, the first buffer hook 200 extends outward, and the second buffer hook 300 retracts relatively inward. During the closing process of the door, the actuator 10 connected to the door approaches the hooks. Because the second buffer hook 300 is relatively retracted, the actuator 10 will pass over the second buffer hook 300, thus smoothly contacting the first buffer hook 200, which then provides the buffering force.
[0004] However, as Figure 2 As shown, if the hook malfunctions and is not in the correct buffer state, that is, if the second buffer hook 300 is not retracted, the starter 10 connected to the door will hit the second buffer hook 300 during the door closing process and will not enter the correct hook position. This will cause damage to the buffer. In severe cases, the buffer and the starter will jam, causing the door to be unable to open and close normally. Utility Model Content
[0005] This invention provides a buffer that can restore the buffer state, so that the actuator can still smoothly hook onto the hook even when the hook is not in the correct buffer state, preventing damage to the buffer and ensuring the normal use of the sliding door.
[0006] To solve the above problems, the present invention adopts the following technical solution:
[0007] An embodiment of this utility model provides a buffer with a recoverable buffer state, including a buffer body and a hook. The surface of the buffer body is provided with a sliding groove, and the hook is disposed in the sliding groove. The hook includes a connector, a first buffer hook, and a second buffer hook. The first buffer hook and the second buffer hook are respectively connected to the two ends of the connector. In the closing direction, the first buffer hook is located in front of the second buffer hook. The second buffer hook can elastically extend and retract in the depth direction of the sliding groove. During the process of the starter moving in the closing direction, the second buffer hook can retract under the squeezing force of the starter so that the starter passes over the second buffer hook.
[0008] In some embodiments, the connector is provided with a clearance groove; the second buffer hook includes a first hook rod and a second hook rod, wherein in the closing direction, the first hook rod is located behind the second hook rod; one end of the first hook rod is connected to the connector, and the other end extends outward; one end of the second hook rod is connected to the outwardly extended end of the first hook rod, and the other end of the second hook rod extends towards the connector and inserts into the clearance groove; when the first hook rod bends towards the connector, the second hook rod can be further inserted into the clearance groove to retract the second buffer hook inward.
[0009] In some embodiments, the first hook is inclined and gradually moves away from the connector in the closing direction.
[0010] In some embodiments, the sidewall of the clearance groove is provided with a limiting protrusion, and one end of the second hook rod inserted into the clearance groove is provided with a protrusion. The limiting protrusion is used to restrict the protrusion from leaving the clearance groove.
[0011] In some embodiments, the outer surface of the protrusion is arc-shaped.
[0012] In some embodiments, reinforcing blocks are provided on both sides of the connection position between the first hook rod and the second hook rod.
[0013] In some embodiments, the connector is further provided with a notch located between the connection point of the first hook rod and the connector and the clearance groove.
[0014] In some embodiments, the connector, the first buffer hook, and the second buffer hook are integrally formed.
[0015] This utility model has at least the following beneficial effects: The second buffer hook of this utility model can elastically extend and retract in the depth direction of the sliding groove. During the process of the starter moving along the closing direction, if the hook is not in the correct buffer state, the starter will touch the second buffer hook first. The second buffer hook retracts under the squeezing force of the starter so as not to block the starter. The starter can pass over the second buffer hook and then smoothly hook with the hook. This can prevent the buffer from being damaged due to hard collision between the starter and the second buffer hook, avoid the buffer and the starter from jamming, and ensure the normal use of the sliding door.

[0030] The utility model provides the following description of reference drawings to help comprehensively understand various embodiments of the utility model as defined by the claims and its equivalents. The description includes various specific details to help understanding, but these details should be regarded as just exemplary. Therefore, those skilled in the art will realize that various changes and modifications can be made to various embodiments described herein without departing from the scope and spirit of the utility model.
[0031] In the description of the utility model, the orientation description such as the orientation or position relationship indicated by up, down, front, back, left, right etc. is based on the orientation or position relationship shown in the drawings, just for the convenience of describing the utility model and simplifying the description, and not indicate or imply that the device or element indicated must have a particular orientation, be constructed and operated in a particular orientation, therefore can not be understood as the limitation of the utility model.
[0032] It should be understood that when an element (e.g., a first element) is "connected with" another element (e.g., a second element), it can be directly connected with the other element or intervening elements (e.g., a third element) can be present.
[0033] The embodiment of the utility model provides a buffer of recoverable buffer state, as shown in the figure, including buffer body 100 and hook spare, the surface of buffer body 100 is provided with sliding slot 110, hook spare sets up in sliding slot 110, and hook spare can slide along sliding slot 110, and the extension direction of sliding slot 110 can be parallel with the sliding direction of door body. Figure 3
[0034] The hook spare includes a connecting piece, a first buffer hook 200, and a second buffer hook 300. The first buffer hook 200 and the second buffer hook 300 are respectively connected with two ends of the connecting piece. The connecting piece can be completely in the sliding slot 110, and at least a part of the first buffer hook 200 and the second buffer hook 300 extends out of the sliding slot 110 to be hookable with the actuator. In the door closing direction, the first buffer hook 200 is located in front of the second buffer hook 300, so that when the actuator moves in the door closing direction, it will first touch the second buffer hook 300.
[0035] The second buffer hook 300 is arranged to be elastically extendable and retractable in the depth direction of the sliding slot 110. When the second buffer hook 300 extends outward, it will block the actuator. When the second buffer hook 300 retracts inward, the second buffer hook 300 will no longer block the actuator, and the actuator can pass the second buffer hook 300.
[0036] As shown in Figure 4 When the actuator 10 moves in the door closing direction, if the hook spare is not in the correct buffer state, the actuator 10 will first touch the second buffer hook 300, and the second buffer hook 300 will retract inward under the extrusion force of the actuator 10.
[0037] As shown in Figure 5 As the actuator 10 continues to move in the door closing direction, the retraction amount of the second buffer hook 300 gradually increases until the actuator 10 passes the second buffer hook 300.
[0038] As shown in Figure 6 After the actuator 10 passes the second buffer hook 300, the actuator 10 will contact the first buffer hook 200, the second buffer hook 300 will elastically reset to the outwardly extended state, and the actuator 10 will further be smoothly hooked with the hook spare.
[0039] Therefore, the embodiment can prevent the actuator 10 from being hard collided with the second buffer hook 300 to cause damage to the buffer, avoid the buffer from being stuck with the actuator 10, and ensure the normal use of the movable door. Therefore, the embodiment can prevent the actuator 10 from being hard collided with the second buffer hook 300 to cause damage to the buffer, avoid the buffer from being stuck with the actuator 10, and ensure the normal use of the movable door.
[0040] In some embodiments, as shown in Figure 3 and Figure 7 The connector 400 is provided with an avoiding slot 410. The second buffer hook 300 comprises a first hook rod 310 and a second hook rod 320, and the first hook rod 310 is located behind the second hook rod 320 in the door closing direction. Thus, when the actuator moves in the door closing direction, it will first touch the first hook rod 310.
[0041] One end of the first hook rod 310 is connected to the connector 400, and the other end extends outward. One end of the second hook rod 320 is connected to the outwardly extending end of the first hook rod 310, and the other end of the second hook rod 320 extends towards the connector 400 and is inserted into the avoiding slot 410. The entire second buffer hook 300 has a bent rod structure, the first hook rod 310 can bend relative to the connector 400, and the avoiding slot 410 provides space for the movement of the second hook rod 320, preventing the second hook rod 320 from being unable to move further towards the connector 400 after abutting against the connector 400.
[0042] When the actuator moves in the door closing direction, the actuator touches the first hook rod 310 and exerts a pressing force on the first hook rod 310. Under the action of the pressing force, the first hook rod 310 bends towards the connector 400, thereby driving the second hook rod 320 to further insert into the avoiding slot 410, so that the entire second buffer hook 300 shrinks inward. As shown in Figure 8 When the second hook rod 320 is inserted into the avoiding slot 410 to the maximum depth, the distance between the entire second buffer hook 300 and the connector 400 is greatly reduced, so that the actuator can pass through the second buffer hook 300.
[0043] In some embodiments, as shown in Figure 3 and Figure 7 The first hook rod 310 is inclined, and in the door closing direction, the first hook rod 310 gradually moves away from the connector 400. When the actuator touches the first hook rod 310, the actuator will generate a component force on the first hook rod 310 in the direction of the thickness of the sliding slot 110 towards the connector 400, so that the first hook rod 310 is more easily bent towards the connector 400, and the first buffer hook 300 can smoothly shrink inward.
[0044] In some embodiments, as shown in Figure 7As shown, the side wall of the avoiding slot 410 is provided with a limiting protrusion 420, and the end of the second hook rod 320 inserted into the avoiding slot 410 is provided with a protrusion 330, and the limiting protrusion 420 is used to limit the protrusion 330 from disengaging from the avoiding slot 410. When the second hook rod 320 moves in the direction of disengaging from the avoiding slot 410, the protrusion 330 will abut against the limiting protrusion 420, thereby playing a limiting role. This can avoid the difficulty of accurately inserting the second hook rod 320 into the avoiding slot 410 again after the second hook rod 320 disengages from the avoiding slot 410, thereby guaranteeing the elastic stretching function of the second buffer hook.
[0045] Further, the outer side surface of the protrusion 330 is arc-shaped, and the surface is more smooth, and in the process of elastic stretching of the second buffer hook, the protrusion 330 moves in the avoiding slot 410, and the smooth structure makes it not easy to scratch the inner wall of the avoiding slot 410, thereby playing a role of preventing damage to the connecting piece 400.
[0046] In some embodiments, as shown in Figure 7 The connecting position of the first hook rod 310 and the second hook rod 320 is provided with a reinforcing block 340 on both sides, and the reinforcing block 340 can strengthen the structural strength of the connecting position of the first hook rod 310 and the second hook rod 320, so that the entire second buffer hook is not easy to break, thereby prolonging the service life.
[0047] In some embodiments, as shown in Figure 7 The connecting piece 400 is also provided with a missing slot 430, and the missing slot 430 is located between the connecting position of the first hook rod 310 and the connecting piece 400 and the avoiding slot 410. The existence of the missing slot 430 makes the structural strength of the connecting position of the first hook rod 310 and the connecting piece 400 decrease, so that the first hook rod 310 is more easy to bend.
[0048] In some embodiments, as shown in Figure 3 and Figure 7 The connecting piece 400, the first buffer hook 200 and the second buffer hook 300 are integrally formed, which is convenient for manufacturing the entire hook piece, and can also strengthen the connecting strength between the connecting piece 400 and the first buffer hook 200 and between the connecting piece 400 and the second buffer hook 300.

Therefore, it should be clear to those skilled in the art that the above description of various embodiments of the present application is only for the purpose of illustration, not for the purpose of limiting the present application as defined by the appended claims and their equivalents.
