Abstract
Description
[Technical Field]
[0001] This utility model relates to a detachable joint for a self-springing buffer roller. [Background Technology]
[0002] The buffers and pulleys installed in the guide rails on the market are generally integral straight bars, which cannot be bent. Due to the small space of the access panel of the guide rail, the integral straight bars are too large to be removed at the same time. Disassembly can only be done by disassembling all the parts, which is very inconvenient to use and difficult to maintain. In order to solve these problems, we propose a new technical solution. [Utility Model Content]
[0003] To solve at least one of the above problems, this utility model proposes a new structural solution. The detachable joint for a self-elastic buffer sheave adopts the following technical solution:
[0004] A detachable joint for a self-springing buffer pulley includes a buffer and a pulley body, wherein the buffer and the pulley body are a detachable assembly structure;
[0005] The pulley body extends out a first mating part, and the end of the first mating part is bent downward to form a first coupling joint. The first coupling joint and the first mating part cooperate to form a first recess. The head end of the buffer extends out a second mating part, and the second mating part is bent upward to form a second coupling joint. The second coupling joint and the second mating part cooperate to form a second recess.
[0006] The pulley body is connected to the buffer, so that the first pair of connectors is connected to the second recess and the second pair of connectors is connected to the first recess. The pulley body and the buffer are linked by the mutual contact between the first pair of connectors and the second pair of connectors.
[0007] Preferably, both the first mating part and the second joint are provided with locking holes, and the locking holes of the first mating part and the second joint are positioned correspondingly. The locking holes are equipped with screws, which pass through the locking holes of both the first mating part and the second joint to assemble the buffer and the pulley body into a whole.
[0008] Preferably, the lock hole of the second pair of connectors extends through the second pair of connectors, and the lock hole of the first mating part is a blind hole.
[0009] Preferably, the corner edges of the second pair of connectors are rounded so that the second pair of connectors can rotate within the first recess.
[0010] Preferably, both the second mating portion and the second mating joint are provided with grooves, and the grooves of the two are connected.
[0011] Preferably, the first pair of connectors is perpendicular to the first mating portion, and the second pair of connectors is perpendicular to the second mating portion.
[0012] The beneficial effects of this utility model compared with the prior art are:
[0013] In this structure, the first mating part, the first coupling joint, the second mating part, and the second coupling joint are connected to form a hook-and-loop connection. The buffer and pulley body, placed within the guide rail, are horizontal. The hook-and-loop buffer and pulley body can move together in a coordinated manner. For disassembly and maintenance, the screws can be removed from below, and the pulley body can be rotated downwards for removal; it is not necessary to remove the entire device as before. The recessed design of the buffer makes it easier for fingers to insert, providing operating space for removing the buffer. It has advantages such as simple structure, compact fit, and reasonable design; therefore, it is a product with superior technical and economic performance. [Attached Image Description]

Detailed Implementation Methods
[0017] The embodiments of this utility model are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout.
[0018] In this utility model, unless otherwise explicitly specified and limited, the terms "assembly," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can also refer to a mechanical connection; they can refer to a direct connection or a connection through an intermediate medium; or they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0019] The following description, in conjunction with the accompanying drawings, further illustrates specific embodiments of the present invention, making the technical solution and beneficial effects of the present invention clearer and more explicit. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.
[0020] The preferred embodiment provided by this utility model is as follows: Figures 1-3As shown, a detachable connector for a self-springing buffer pulley includes a buffer 1 and a pulley body 2, wherein the buffer 1 and the pulley body 2 are a detachable assembly structure.
[0021] The pulley body 2 extends out a first mating portion 21, and the end of the first mating portion 21 is bent downward to form a first mating joint 22. The first mating joint 22 and the first mating portion 21 cooperate to form a first recess 23. The head end of the buffer 1 extends out a second mating portion 24, and the second mating portion 24 is bent upward to form a second mating joint 25. The second mating joint 25 and the second mating portion 24 cooperate to form a second recess 26. The first mating joint 22 is perpendicular to the first mating portion 21, and the second mating joint 25 is perpendicular to the second mating portion 24, so that the pulley body 2 and the buffer 1 can be better connected.
[0022] The pulley body 2 is connected to the buffer 1, so that the first pair of connectors 22 is connected to the second recess 26 and the second pair of connectors 25 is connected to the first recess 23. The pulley body 2 and the buffer 1 are linked by the first pair of connectors 22 and the second pair of connectors 25 abutting against each other.
[0023] Both the first mating part 21 and the second mating joint 25 are provided with locking holes 27, and the locking holes 27 of the first mating part 21 and the second mating joint 25 are positioned correspondingly. The locking holes 27 can be screw holes, and screws are provided in the locking holes 27. The screws pass through the locking holes 27 of both the first mating part 21 and the second mating joint 25 to assemble the buffer 1 and the pulley body 2 into a whole. The screws can make the connection between the buffer 1 and the pulley body 2 more secure. The locking hole 27 of the second mating joint 25 extends through the second mating joint 25. The locking hole 27 of the first mating part 21 is a blind hole, which facilitates the removal of the screw from below.
[0024] The corner edge 28 of the second connector 25 is rounded so that the second connector 25 can rotate within the first recess 23. Both the second mating part 24 and the second connector 25 are provided with grooves 29, and the grooves of the two are connected to each other, which facilitates the insertion and picking operation of fingers.
[0025] In this structure, the first mating part 21, the first mating joint 22, the second mating part 24, and the second mating joint 25 are connected to each other to form a hook-and-loop connection. The buffer 1 and the pulley 2, placed in the guide rail, are horizontal. The buffer 1 and the pulley 2 in the hook-and-loop connection can move together. When disassembly and maintenance are required, the screws can be removed from below, and then the pulley 2 can be rotated downwards to remove it. The groove design of the buffer 1 makes it easier for fingers to insert and provides operating space for removing the buffer 1.
