Description

Technical Field

[0001] The present application relates to the technical field of nuts, and more specifically, to a sliding nut. Background Art

[0002] In the existing fastener technology field, nuts, as a common connecting element, are widely used in various machines and equipment. At present, most of the common nuts on the market are fixed type, that is, the fixed connection between the nut and the bolt or stud is achieved by rotating the nut.

[0003] However, the tightening and loosening of the nut requires the aid of tools, which is not convenient to operate. Secondly, in some special environments, such as narrow space or occasions where frequent disassembly is required, the use of the fixed nut will be greatly restricted and difficult to install quickly.

[0004] In view of this, we propose a sliding nut. Utility Model Content

[0007] Optionally, sealing rings are fixedly connected to the front and rear of the outer wall of the nut head, and the outer wall of the sealing ring fits with the inner wall of the sliding push block.

[0008] Optionally, a gasket is fixedly connected to one end of the nut head.

[0009] Optionally, an oil filling hole is provided on one side of the upper end surface of the sliding push block, and the oil filling hole is communicated with the cavity.

[0010] Optionally, a threaded tube is fixedly connected to the inside of the oil filling hole, and a threaded head is rotatably connected to the top of the inside of the threaded tube through a thread.

[0011] One or more technical solutions provided in the technical solution of this application have at least the following technical effects or advantages:

[0012] The present application opens a cavity for storing lubricating oil inside the sliding push block, and injecting lubricating oil can reduce the friction between the threaded strip and the threaded rod and between the limit ring and the nut head, keeping the connection between them lubricated, which helps to make the sliding push block and the nut head move more smoothly, thereby maintaining the smooth operation of the entire equipment. By reducing friction, the wear between parts can be effectively reduced, thereby extending the service life of the equipment. The effective use of lubricating oil can ensure that the equipment will not experience jams or failures due to friction during operation, making the operation smoother and more efficient.

[0017] The present application is further described in detail below in conjunction with the accompanying drawings.

[0018] Reference Figure 1-Figure 3 The embodiment of the present application provides a sliding nut, including a nut head 1, the inner wall of the nut head 1 is fixedly connected with a threaded strip 2, the outer wall of the nut head 1 is penetrated with a plurality of through holes 3, the periphery of the nut head 1 is provided with a sliding push block 4, the inner wall of the sliding push block 4 is fixedly connected with a limiting ring 5, the inner wall of the limiting ring 5 and the outer wall of the nut head 1 are clearance-matched, a cavity 8 is provided inside the sliding push block 4, a connecting hole 12 is penetrated inside the limiting ring 5, and the connecting hole 12 extends into the cavity 8, a cavity 8 for storing lubricating oil is provided inside the sliding push block 4, and injecting lubricating oil can reduce the friction between the threaded strip 2 and the threaded rod and the limiting ring 5 and the nut head 1, keep the connection between them lubricated, help to make the sliding push block 4 and the nut head 1 more smooth when moving, thereby maintaining the smooth operation of the entire device, and by reducing friction, the wear between parts can be effectively reduced, thereby extending the service life of the device, and the effective use of lubricating oil can ensure that the device will not have jams or failures caused by friction during operation, making the operation smoother and more efficient.

[0019] Reference Figure 1-Figure 3A sealing ring 6 is fixedly connected to the front and rear of the outer wall of the nut head 1, and the outer wall of the sealing ring 6 fits with the inner wall of the sliding push block 4. A gasket 7 is fixedly connected to one end of the nut head 1. An oil filling hole 9 is opened on one side of the upper end surface of the sliding push block 4, and the oil filling hole 9 is connected to the cavity 8. A threaded tube 10 is fixedly connected to the inside of the oil filling hole 9, and a threaded head 11 is connected to the top of the threaded tube 10 through threaded rotation, which plays a sealing role and prevents the staff from injecting lubricating oil.

[0020] Working principle: The staff first turns the threaded head 11 inside the oil filling hole 9 to open it, and injects the lubricating oil into the cavity 8 inside the sliding push block 4 through the threaded tube 10, and then installs the threaded head 11 back into the threaded tube 10. When in use, first turn the sliding push block 4 with the oil filling hole 9 facing downward, and the lubricating oil will pass through the limiting ring 5 through the connecting hole 12 and enter the gap between the limiting ring 5 and the nut head 1. Then the lubricating oil will enter the threaded strip 2 through the through hole 3 on the nut head 1. The staff puts the nut head 1 on the threaded rod without turning the nut head 1 and pushes it. The sliding push block 4 is limited by the limiting ring 5 and the sealing ring 6, and the sliding push block 4 moves to drive the nut head 1 to rotate and move. When the rotation of the nut head 1 is blocked, the sliding push block 4 is rotated, the connecting hole 12 is tilted, and the lubricating oil enters the threaded strip 2 through the connecting hole 12 and the through hole 3. The lubricating oil lubricates the connection between the threaded strip 2 and the threaded rod to reduce friction, thereby improving the smoothness of the movement of the nut head 1 until the installation is completed. When disassembling, pull the sliding push block 4, and the sliding push block 4 moves to drive the nut head 1 to rotate until the sliding push block 4 and the nut head 1 are removed.

[0021] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
