Description

Technical Field

[0001] The embodiment of the utility model relates to the technical field of nuts, and in particular to an anti-slip nut. Background Art

[0002] Bolts are a relatively common mechanical fixing component, which is fixed by interlocking the bolts and nuts on the outer wall. When the battery compartment of some equipment needs to be installed and fixed, a combined receiving mold is usually used to put the corresponding nuts in, and then tighten and fix them with bolts. It is necessary to prevent the nuts from sliding and detaching.

[0003] The existing patent number CN219509986U discloses an anti-slip nut, wherein the anti-slip nut comprises: a nut body, the nut body has a protrusion, and the nut body has a plurality of evenly distributed first protrusions on one side close to the protrusion, and the plurality of first protrusions are provided with a film capable of destroying the surface of the profile. The utility model can achieve the advantages of anti-static, simple structure, convenient assembly, high practicality and anti-slip by effectively utilizing its own structural configuration.

[0004] The above-mentioned patent only achieves anti-slip by simply protruding on the surface. The method is relatively simple and prone to slippage. At the same time, the nut can prevent it from falling out during use, but the nut lacks fixation on the bolt. During long-term use, the bolt still has the risk of rotation and detachment. Utility Model Content

[0005] To this end, an embodiment of the utility model provides an anti-slip nut to solve the problem in the prior art that the nut needs to be restricted to prevent it from falling off, and the bolt needs to be limited to prevent it from rotating in the opposite direction and falling off.

[0006] In order to achieve the above purpose, the embodiment of the utility model provides the following technical solutions:

[0007] An anti-slip nut comprises a nut sleeve, a sleeve tube and a sealing ring, wherein the top outer wall of the nut sleeve is sleeved with the sleeve tube, the top of the sleeve tube is provided with a sealing ring, the inner bottom end of the nut sleeve is provided with an elastic ball, and the outer wall of the nut sleeve near the top is connected with a plurality of clamping blocks in a surrounding sliding manner;

[0008] A thread groove is arranged at the inner center of the nut sleeve for threaded connection, and accommodating grooves are arranged around the outer wall center and the top of the nut sleeve.

[0009] Furthermore, the outer wall of the nut sleeve is provided with an anti-slip strip in a surrounding manner, and the anti-slip strip is vertically fixed to the outer wall of the nut sleeve, and the bottom of the nut sleeve is fixedly connected with a plurality of fixing strips in a surrounding array.

[0010] Furthermore, a fixing ring is fixedly connected around the outer wall of the top of the sleeve pipe. A surrounding spring is connected around the outer wall of the accommodating groove at the bottom of the sleeve pipe. An installation groove for correspondingly accommodating the sealing ring is formed at the top of the fixing ring. The inner part of the sleeve pipe is slidably sleeved with the outer wall of the accommodating groove. The outer wall of the fixing ring corresponds to the outer wall of the nut sleeve. Anti-slip lines are provided on the top of the sealing ring.

[0011] Furthermore, the edges of the clamping blocks near the center of the nut sleeve are inclined to one side, and the side of the clamping block near the center of the nut sleeve is inclined downward. A pressing spring is fixedly connected to the side of the clamping block far from the center of the nut sleeve. A plurality of sliding grooves are formed at the corresponding positions of the inner part of the nut sleeve for the clamping blocks. The outer wall of the clamping block slides with the pressing spring.

[0012] Furthermore, the center of the bottom end inside the nut sleeve is fixedly connected to an elastic ball. A tapered groove is formed at the bottom end inside the nut sleeve, and the center of the tapered groove is arc-shaped and inclined downward.

[0013] Furthermore, the end of the pressing spring far from the clamping block is fixedly connected to the inner wall of the sliding groove. A bolt is connected and installed inside the nut sleeve, and a plurality of grooves are vertically arranged on the outer wall of the bolt.

[0014] The embodiments of the present utility model have the following advantages:

[0015] 1. By the blocking of the accommodating groove, the nut sleeve is effectively prevented from being pulled off. Furthermore, through the corresponding fitting of the anti-slip strips and the fixing strips with the workpiece, the rotation of the nut sleeve can be further blocked to keep its position fixed. When in use, the corresponding sealing ring can also be made to fit and press against the surface of the workpiece. Then, through the pressing of the surrounding spring, the nut sleeve is always pushed in the reverse direction, and thus it is pressed into the corresponding workpiece groove to prevent it from moving or disengaging. In addition, the rotation of the nut sleeve can be prevented through the fitting of the sealing ring.

[0016] 2. The bolt presses the elastic ball, thereby compressing the elastic ball. Through the reverse pushing force of the elastic ball, the circumferential thread on the outer wall of the threaded bolt can be kept in close fit with the thread groove inside the nut sleeve. At the same time, since grooves are provided on the outer wall of the threaded bolt, when the threaded bolt rotates in the reverse direction, the grooves can be engaged with the corresponding clamping blocks to prevent it from rotating in the reverse direction, thereby preventing the threaded bolt from disengaging.

[0026] ReferenceFigures 1-5 An anti-slip nut as shown, comprising a nut sleeve 1, a sleeve pipe 2 and a sealing ring 3. The outer wall of the top end of the nut sleeve 1 is sleeved with the sleeve pipe 2. A sealing ring 3 is arranged at the top of the sleeve pipe 2. An elastic ball 4 is arranged at the inner bottom end of the nut sleeve 1. A plurality of clamping blocks 5 are slidably connected around the outer wall of the nut sleeve 1 near the top; a thread groove is formed at the center of the inner part of the nut sleeve 1 for thread connection. Accommodating grooves 101 are formed at the center of the outer wall and the top of the nut sleeve 1. The inner part of the sleeve pipe 2 is slidably sleeved with the outer wall of the accommodating groove 101.

[0027] Reference Figure 3 、 Figure 4 As shown, anti-slip strips 102 are formed around the outer wall of the nut sleeve 1. The anti-slip strips 102 are vertically fixed to the outer wall of the nut sleeve 1. A plurality of fixing strips 103 are fixedly connected in a circumferential array at the bottom of the nut sleeve 1. A fixing ring 201 is fixedly connected around the outer wall of the top of the sleeve pipe 2. A surrounding spring 202 is connected around the outer wall of the accommodating groove 101 at the bottom of the sleeve pipe 2. An installation groove 301 corresponding to the accommodation of the sealing ring 3 is formed at the top of the fixing ring 201. The outer wall of the fixing ring 201 corresponds to the outer wall of the nut sleeve 1. Anti-slip patterns are arranged on the top of the sealing ring 3, which can effectively prevent the nut sleeve 1 from being pulled off through the blocking effect of the accommodating groove 101. Furthermore, through the corresponding fitting and extrusion of the anti-slip strips 102 and the fixing strips 103 with the workpiece, the rotation of the nut sleeve 1 can be further blocked to keep its position fixed.

[0028] Reference Figure 2 、 Figure 5 As shown, the edges of the clamping blocks 5 near the center of the nut sleeve 1 are inclined to one side, and the side of the clamping blocks 5 near the center of the nut sleeve 1 is inclined downward. A pressing spring 501 is fixedly connected to the side of the clamping blocks 5 far from the center of the nut sleeve 1. A plurality of sliding grooves 502 are formed at the corresponding positions of the inner part of the nut sleeve 1 and the clamping blocks 5. The outer wall of the clamping blocks 5 slides with the pressing spring 501. One end of the pressing spring 501 far from the clamping blocks 5 is fixedly connected to the inner wall of the sliding groove 502. A bolt is installed and connected inside the nut sleeve 1, and a plurality of grooves are vertically arranged on the outer wall of the bolt. At the same time, due to the grooves arranged on the outer wall of the threaded bolt, when the threaded bolt rotates reversely, the grooves can be clamped with the corresponding clamping blocks 5 to achieve blocking, avoiding its reverse rotation, and further preventing the threaded bolt from coming off.

[0029] Reference Figure 5As shown, the center of the inner bottom end of the nut sleeve 1 is fixedly connected to the elastic ball 4. A tapered groove 401 is provided at the inner bottom end of the nut sleeve 1, and the center of the tapered groove 401 is arcuately inclined towards the bottom, so that the threaded bolt squeezes the elastic ball 4, thereby compressing the elastic ball 4. Through the reverse driving force of the elastic ball 4, the circumferential threads on the outer wall of the threaded bolt can be kept in close fit with the threads of the thread groove inside the nut sleeve 1.

[0030] Working principle: When in use, the device can be conveniently connected and installed with the corresponding workpiece. A groove that fits the anti-slip strip 102 is provided inside the workpiece, and the side wall of the groove inside the workpiece is clamped with the receiving groove 101. Thus, through the blocking effect of the receiving groove 101, it is effectively avoided that the nut sleeve 1 is pulled off. Furthermore, through the fitting and extrusion of the anti-slip strip 102 and the fixing strip 103 with the corresponding part of the workpiece, the rotation of the nut sleeve 1 can be further blocked to keep its position fixed. When in use, the corresponding sealing ring 3 can also be made to fit and squeeze against the surface of the workpiece. Thus, through the extrusion of the surrounding spring 202, the reverse push on the nut sleeve 1 is always maintained, and the receiving groove 101 is squeezed inside the corresponding groove of the workpiece to prevent the nut sleeve 1 from moving and detaching. In addition, through the fitting of the sealing ring 3 with the workpiece, the rotation of the sleeve pipe 2 can be blocked, thereby preventing the nut sleeve 1 from rotating.

[0031] When in use, the threaded bolt with grooves on its outer wall can be conveniently inserted into the internal thread groove of the nut sleeve 1. Since the top of the block 5 is inclined from top to bottom, when the threaded bolt moves into the thread groove, the block 5 is squeezed and compressed. At the same time, when the threaded bolt rotates, since the side wall of the block 5 is inclined to one side, even when the block 5 is clamped with the groove on the outer wall of the threaded bolt, it can avoid blocking the forward rotation of the threaded bolt into the nut sleeve 1. Thus, the threaded bolt squeezes the elastic ball 4, thereby compressing the elastic ball 4. Through the reverse driving force of the elastic ball 4, the circumferential threads on the outer wall of the threaded bolt can be kept in close fit with the threads of the thread groove inside the nut sleeve 1. At the same time, since there are grooves on the outer wall of the threaded bolt, when the threaded bolt rotates in the reverse direction, the grooves can be clamped with the corresponding block 5 to achieve blocking, avoiding its reverse rotation, and thus preventing the threaded bolt from detaching.

[0032] Although the present invention has been described in detail above with general descriptions and specific embodiments, based on the present invention, some modifications or improvements can be made, which are obvious to those skilled in the art. Therefore, these modifications or improvements made without departing from the spirit of the present invention all fall within the scope of protection required by the present invention.
