TECHNICAL FIELD

[0001] The utility model belongs to screw technology field, especially relate to a screw and nut which is easy to disassemble and assemble. BACKGROUND

[0002] Screw and nut is a common mechanical fastening and transmission assembly, which is composed of a screw (external thread shaft) and a nut (internal thread sleeve) in pairs, and force transmission, position adjustment or fastening connection are achieved through thread engagement. The screw is usually made of metal and has high-precision threads, while the nut can be embedded in a base or used independently,

[0003] When the screw and nut is used for a long time, the internal lubricating grease will mix with dust and other impurities to form oil sludge and other impurities, which will block the thread connection and make the rotation not smooth. The oil sludge can easily damage the threads, so the threads need to be cleaned. The conventional nut has an integrated structure, which is difficult to clean. Therefore, it is necessary to develop a screw and nut that is easy to disassemble and assemble. SUMMARY

[0004] The utility model aims at the above-mentioned problems existing in the prior art, and provides a screw and nut which is easy to clean, disassemble and assemble.

[0005] The utility model discloses a screw and nut which is easy to disassemble and assemble, characterized in that it comprises a screw and a nut, a plurality of thread assemblies are arranged in the nut, the thread assemblies are provided with connecting threads that are in communication with each other, the thread assemblies are provided with accommodating cavities on both sides, magnets are arranged in the accommodating cavities, locking sleeves are arranged on the outer walls of the thread assemblies, locking rings are arranged at both ends of the nut, and an anti-loosening assembly is arranged at the bottom of the nut.

[0006] In the screw and nut which is easy to disassemble and assemble, guiding grooves are arranged in the thread assemblies, and a plurality of guiding strips are arranged on the locking sleeves.

[0007] In the screw and nut which is easy to disassemble and assemble, a plurality of elastic claws A are arranged on the locking sleeves, steel rings that play a connecting role are arranged between the elastic claws A, a plurality of detachable elastic claws B are arranged on the locking rings, the elastic claws A and the elastic claws B are arranged alternately, and limiting holes that are in communication with each other are arranged in the thread assemblies and the locking rings.

[0008] Compared with the prior art, the screw and nut which is easy to disassemble and assemble is provided with a plurality of detachable thread assemblies in the nut. The thread assemblies in the nut can be fully cleaned by detaching the thread assemblies. Damaged thread assemblies can also be connected quickly through the anti-loosening assembly. The elastic column B clamps the locking ring and the thread assembly to prevent the locking ring at the end from loosening and rotating, which can cause the failure of fixation.

DETAILED DESCRIPTION

[0015] The following is a specific embodiment of the present application and further describes the technical scheme of the present application in combination with the drawings, but the present application is not limited to these embodiments.

[0016] As shown in Figure 1 , 2 , 3, 5, the detachable screw rod 1 and screw sleeve 2 comprise the screw rod 1 and the screw sleeve 2, a plurality of thread assemblies 8 are arranged in the screw sleeve 2, the thread assemblies 8 are provided with connecting threads 7 in communication with each other, the thread assemblies 8 are provided with containing cavities 10 on both sides, magnets 9 are arranged in the containing cavities 10, locking sleeves 5 are arranged on the outer walls of the thread assemblies 8, locking screw rings 6 are arranged at both ends of the screw sleeve 2, and anti-loosening assemblies 3 are arranged at the bottom of the screw sleeve 2. Before use, select appropriate thread assemblies 8 to connect the assemblies and put them into the locking sleeves 5, prevent the magnets 9 from being in the containing cavities 10, smear lubricating oil on the thread assemblies 8, and then connect the screw sleeve 2 and the screw rod 1. When the screw rod 1 and the screw sleeve 2 rotate, the exposed threads can absorb various impurities, including metal debris and air dust. The impurities and the oil form an oil sludge, which is attracted to the containing cavities 10 by the magnets 9, thereby reducing the wear of the threads when the threads are engaged.

[0017] Preferably, guide grooves 15 are arranged through the thread assemblies 8, and a plurality of guide bars 13 are arranged on the locking sleeves 5, so that the guide grooves 15 and the guide bars 13 limit the thread assemblies 8 to prevent them from rotating in the locking sleeves 5.

[0018] The locking sleeve 5 is preferably provided with a plurality of elastic claws A11, and a steel ring 4 is arranged between the elastic claws A11 for connection. The locking ring 6 is also provided with a plurality of detachable elastic claws B12. The elastic claws A11 and the elastic claws B12 are arranged at intervals. The threaded assembly 8 and the locking ring are both provided with a limiting hole 14 in communication. During installation, the elastic clamping column is installed in the limiting hole 14, and then the steel ring 4 is used to connect all the elastic claws A11 and the elastic claws B12. The elastic claws B12 prevent the locking ring 6 from loosening and rotating to cause failure of fixation.

[0019] The specific embodiments described herein are merely illustrative of the spirit of the present application. Those skilled in the art to which the present application belongs can make various modifications or supplements to the described specific embodiments or use similar ways to replace, but will not deviate from the spirit of the present application or exceed the scope defined by the appended claims.

[0020] Although the terms such as screw rod 1, screw sleeve 2, anti-loosening assembly 3, steel ring 4, locking sleeve 5, locking ring 6, connecting thread 7, threaded assembly 8, magnet 9, accommodating cavity 10, elastic claw A11, elastic claw B12, guide strip 13, limiting hole 14, guide groove 15, etc. are used more frequently herein, the possibility of using other terms is not excluded. The use of these terms is only for more convenient description and explanation of the essence of the present application; any kind of additional limitation is contrary to the spirit of the present application.
