Description

Technical Field

[0001] This utility model relates to the field of locking sleeve technology, specifically a self-limiting locking sleeve assembly. Background Technology

[0002] The adapter sleeve is an important component in the field of mechanical engineering. It is mainly used to fix rotating parts such as bearings, solves the problem of fixing rotating parts, and is the key to the efficient operation of modern mechanical equipment. It can tightly connect various components together and ensure the stable operation of the entire system.

[0003] Traditional adapter sleeve structures typically rely on manual tightening of the nut to achieve a fastening effect. However, manual tightening makes it difficult to precisely control the tightening force and position, which can easily lead to over-tightening of the adapter sleeve, damage to the threads, and shorten the service life of the adapter sleeve. Utility Model Content

[0004] The purpose of this utility model is to provide a self-limiting locking sleeve assembly, which solves the problem that traditional locking sleeve structures usually rely on manual tightening of nuts to achieve a fastening effect. However, manual tightening is difficult to control precisely in terms of tightening force and position, which can easily lead to over-tightening of the locking sleeve, damage to the threads, and shorten the service life of the locking sleeve.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a self-limiting locking sleeve assembly, comprising a locking sleeve, one end of which has a threaded groove, an outer surface of which has a receiving groove, and an outer surface of which has an installation groove. The installation groove and the receiving groove are internally connected. A limiting component is installed inside the installation groove, and the limiting end of the limiting component extends into the receiving groove. A nut is threadedly connected to the outside of the threaded groove, and one end of the nut has several limiting grooves. The interiors of the several limiting grooves abut against the limiting end of the limiting component.

[0007] Furthermore, the limiting component includes springs, the number of which is fixed at several, and all springs are fixedly installed inside the mounting groove.

[0008] Furthermore, the mounting groove is provided with a mounting plate inside, and one side of the mounting plate is fixedly connected to one end of several springs.

[0009] Furthermore, an extension plate is fixedly mounted on the outer surface of the mounting plate, and the extension plate extends into the interior of the receiving groove.

[0010] Furthermore, a fixing plate is fixedly installed at one end of the extension plate, and a plurality of limiting plates are fixedly installed on the lower surface of the fixing plate.

[0011] Furthermore, the limiting plates all abut against the inside of the limiting groove.

[0012] This utility model has the following beneficial effects:

[0013] (1) In this utility model, when the nut is screwed into the threaded groove, the outer surface of the nut will press the limiting plate. The limiting plate drives the extension plate to move through the fixing plate. The extension plate drives the mounting plate to move inside the mounting groove. While the mounting plate moves, it presses the spring. When the nut is tightened to the position, the position of the limiting plate and the limiting groove coincides. The spring rebounds and pushes the limiting plate into the limiting groove. The cooperation between the limiting plate and the limiting groove prevents the nut from rotating further, thereby preventing the set sleeve from being over-tightened or loosened. It realizes the automatic limiting function of the set sleeve, ensuring that the nut can accurately reach the set position during the tightening process, avoiding the problem of over-tightening or loosening.

[0014] (2) When the nut needs to be removed, the mounting plate is pulled back and the spring is squeezed. The mounting plate drives the limiting plate to disengage from the inside of the limiting groove through the extension plate and the fixing plate, thereby releasing the nut from the limiting position. Then the nut can be unscrewed, which achieves the effect of easily releasing the nut from the limiting position and improves the overall work efficiency.

[0015] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0024] Please see Figures 1-4 As shown, this utility model is a self-limiting locking sleeve assembly, including a locking sleeve 1. One end of the locking sleeve 1 has a threaded groove 103. The outer surface of the locking sleeve 1 has a receiving groove 101 and an installation groove 102. The installation groove 102 and the receiving groove 101 are connected internally. A limiting component 3 is installed inside the installation groove 102. The limiting end of the limiting component 3 extends into the receiving groove 101. A nut 2 is threadedly connected to the outside of the threaded groove 103. One end of the nut 2 has a plurality of limiting grooves 201. The interior of the plurality of limiting grooves 201 abuts against the limiting end of the limiting component 3.

[0025] The limiting component 3 includes a spring 301, the number of which is fixed to a certain number, and all springs 301 are fixedly installed inside the mounting groove 102.

[0026] The mounting slot 102 is provided with a mounting plate 302 inside, and one side of the mounting plate 302 is fixedly connected to one end of several springs 301;

[0027] An extension plate 303 is fixedly mounted on the outer surface of the mounting plate 302, and the extension plate 303 extends into the interior of the receiving groove 101.

[0028] A fixing plate 304 is fixedly installed at one end of the extension plate 303, and a number of limiting plates 305 are fixedly installed on the lower surface of the fixing plate 304.

[0029] The limiting plates 305 all abut against the inside of the limiting grooves 201;

[0030] When nut 2 is screwed into threaded groove 103, the outer surface of nut 2 will press against limiting plate 305. Limiting plate 305 drives extension plate 303 to move through fixing plate 304. Extension plate 303 drives mounting plate 302 to move inside mounting groove 102. While mounting plate 302 moves, it presses spring 301. When nut 2 is tightened to the position, the position of limiting plate 305 and limiting groove 201 coincides. Spring 301 rebounds and pushes limiting plate 305 into the limiting groove 201. The cooperation between limiting plate 305 and limiting groove 201 prevents nut 2 from rotating further, thereby preventing over-tightening or loosening of locking sleeve 1. It realizes the automatic limiting function of locking sleeve 1, ensuring that nut 2 can accurately reach the set position during tightening, avoiding the problem of over-tightening or loosening.

[0031] When it is necessary to remove nut 2, pull the mounting plate 302 backward and squeeze the spring 301. The mounting plate 302 drives the limiting plate 305 to disengage from the inside of the limiting groove 201 through the extension plate 303 and the fixing plate 304, thereby releasing the limitation on nut 2. Then, nut 2 can be unscrewed, which can facilitate the release of the limitation on nut 2 and improve the overall work efficiency.

[0032] In use, first screw the nut 2 into the threaded groove 103. The outer surface of the nut 2 will press against the limiting plate 305. The limiting plate 305 drives the extension plate 303 to move through the fixing plate 304. The extension plate 303 drives the mounting plate 302 to move inside the mounting groove 102. While the mounting plate 302 moves, it presses against the spring 301. When the nut 2 is tightened to the position, the limiting plate 305 and the limiting groove 201 are aligned. The spring 301 rebounds and pushes the limiting plate 305 into the limiting groove 201. The cooperation between the limiting plate 305 and the limiting groove 201 prevents the nut 2 from rotating further, thereby preventing the locking sleeve 1 from being over-tightened or loosened. This realizes the automatic limiting function of the locking sleeve 1, ensuring that the nut 2 can accurately reach the set position during the tightening process and avoiding the problem of over-tightening or loosening.

[0033] When it is necessary to remove nut 2, pull the mounting plate 302 backward and squeeze the spring 301. The mounting plate 302 drives the limiting plate 305 to disengage from the inside of the limiting groove 201 through the extension plate 303 and the fixing plate 304, thereby releasing the limitation on nut 2. Then, nut 2 can be unscrewed, which can facilitate the release of the limitation on nut 2 and improve the overall work efficiency.
