Description

Technical Field

[0001] This utility model relates to the field of coupling technology, and in particular to a slider coupling. Background Technology

[0002] A slider coupling is a rigid coupling without elastic elements. It transmits torque and compensates for certain axial, radial, and angular misalignments through an intermediate slider.

[0003] Traditional slider couplings employ a two-end connecting cylinder structure, each fixed to one of the two connected objects. This design has significant mechanical drawbacks in actual operation: when the two connected objects experience relative displacement, the coupling is subjected to bidirectional compressive loads. This continuous compressive force increases friction between the internal groove and the slider, accelerating wear on the contact surfaces and shortening its service life. Therefore, this solution proposes a slider coupling to address these issues. Utility Model Content

[0004] The purpose of this invention is to provide a slider coupling to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a slider coupling, comprising:

[0006] First connecting shaft;

[0007] A second connecting shaft is disposed on one side of the first connecting shaft;

[0008] A docking assembly includes a second disk disposed on one side of a first connecting shaft, an elastic block fixedly connected to one side of the second disk, a first disk fixedly connected to one side of the elastic block, a first sliding member disposed at the connection between the first connecting shaft and the second disk, and a second sliding member disposed at the connection between the second connecting shaft and the first disk.

[0009] A connecting component is disposed at the connection between the first disk and the second disk, and the connecting component is used to connect the first disk and the second disk.

[0010] Preferably, the first slider includes a first slider fixedly connected to the other side of the second disk, and a first groove is provided on one side of the first connecting shaft, with the first slider inserted into the inside of the first groove.

[0011] Preferably, the second slider includes a second slider fixedly connected to one side of the first disk, and a second groove is provided on one side of the second connecting shaft, with the second slider inserted into the interior of the second groove.

[0012] Preferably, the connecting component includes a square block fixedly connected to one side of the second disk, and a square groove is provided on the other side of the first disk, with the square block inserted into the inside of the square groove.

[0013] Preferably, a limiting cavity is formed on the inner wall of one side of the square groove, and a limiting block is fixedly connected to one side of the square block, with the limiting block inserted into the interior of the limiting cavity.

[0014] Preferably, the elastic block has a through hole in the middle, and the square block is inserted into the through hole.

[0015] The technical effects and advantages of this utility model are as follows:

[0016] This utility model, through the design of a first disc, a second disc, an elastic block, and a connecting component, allows the coupling to be used when it connects two objects. When the coupling is squeezed by the two objects, the elastic block absorbs the squeezing force of the two objects, reducing the squeezing force on the slider of the coupling and thus reducing the friction on the coupling.

[0022] 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.

[0023] This utility model provides, for example Figure 1-4 Shown:

[0024] Example 1:

[0025] A slider coupling includes:

[0026] First connecting shaft 1;

[0027] The second connecting shaft 2 is disposed on one side of the first connecting shaft 1;

[0028] The docking assembly 3 includes a second disk 303 disposed on one side of the first connecting shaft 1, an elastic block 302 fixedly connected to one side of the second disk 303, a first disk 301 fixedly connected to one side of the elastic block 302, a first sliding member 4 disposed at the connection between the first connecting shaft 1 and the second disk 303, and a second sliding member 5 disposed at the connection between the second connecting shaft 2 and the first disk 301.

[0029] The connecting component 6 is located at the connection between the first disk 301 and the second disk 303, and is used to connect the first disk 301 and the second disk 303.

[0030] It should be noted that a mounting groove is provided on one side of both the first connecting shaft 1 and the second connecting shaft 2, and a mounting hole is provided on the inner wall of the middle of the mounting groove. In use, the shaft is connected to the shaft of the object through the mounting groove, and then the shaft is connected to the connecting shaft through a pin or bolt. The first disc 301 and the second disc 303 are respectively fixedly connected to both sides of the elastic block 302. When the first disc 301 or the second disc 303 is subjected to continued pressure from the object, the first disc 301 and the second disc 303 will be pressed towards one side of the elastic block 302, and the elastic block 302 will absorb the pressure of the object on the first disc 301 and the second disc 303.

[0031] Specifically, the first sliding member 4 includes a first slider 401 fixedly connected to the other side of the second disk 303, and a first groove 402 is provided on one side of the first connecting shaft 1, with the first slider 401 inserted into the inside of the first groove 402.

[0032] Specifically, the second sliding member 5 includes a second slider 501 fixedly connected to one side of the first disk 301, and a second groove 502 is provided on one side of the second connecting shaft 2, with the second slider 501 inserted into the interior of the second groove 502.

[0033] It should be noted that the first slider 401 and the second slider 501 are arranged perpendicularly. The first groove 402 and the second groove 502 are adapted to the first slider 401 and the second slider 501, respectively, so that the first slider 401 and the second slider 501 are inserted through the first groove 402 and the second groove 502 on opposite sides of the first connecting shaft 1 and the second connecting shaft 2. When one of the connecting shafts rotates, the first disk 301, the second disk 303 and the other connecting shaft are driven to rotate by the obstruction of the groove and the slider, thereby completing the transmission of rotational force. In use, the first connecting shaft 1 and the second connecting shaft 2 are first connected to the shafts of the two objects respectively. When one of the shafts drives the first connecting shaft 1 or the second connecting shaft 2 to move, the first connecting shaft 1 or the second connecting shaft 2 can slide on the first slider 401 or the second slider 501. When the slider does not move out of the groove, the rotational force can still be transmitted, thereby transmitting torque and compensating for deviations through multiple sliders in the middle.

[0034] Example 2:

[0035] Connecting component 6 is used in the slider coupling in Embodiment 1;

[0036] Specifically, the connecting component 6 includes a square block 601 fixedly connected to one side of the second disk 303, and a square groove 603 is provided on the other side of the first disk 301, with the square block 601 inserted into the inside of the square groove 603.

[0037] Specifically, a limiting cavity 605 is provided on the inner wall of one side of the square groove 603, and a limiting block 604 is fixedly connected to one side of the square block 601. The limiting block 604 is inserted into the interior of the limiting cavity 605.

[0038] Specifically, the elastic block 302 has a through hole 602 in the middle, and the square block 601 is inserted into the inside of the through hole 602.

[0039] It should be noted that the area of ​​the horizontal longitudinal section of the limiting block 604 is larger than the area of ​​the horizontal longitudinal section of the square groove 603, so that the limiting block 604 cannot move out of the limiting cavity 605 through the square groove 603. Thus, the limiting cavity 605 limits the movement distance of the limiting block 604, and the limiting block 604 limits the movement distance of the square block 601 and the second disk 303, preventing the square block 601 from moving out of the square groove 603. The square block 601 is adapted to the square groove 603, and both of them have a square horizontal longitudinal section. Through the design of the square block 601 and the square groove 603, the first disk 301 and the second disk 303 can rotate simultaneously.

[0040] Finally, it should be noted that the above description is only 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.
