Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of nuts, in particular to a novel nut with an anti-falling structure. Background Art
[0002] A nut is a part that is screwed together with a bolt or a screw to fasten the parts. It is a component that all manufacturing machinery must use. According to the different materials, it is divided into several types such as carbon steel, stainless steel, and non-ferrous metals.
[0003] However, the traditional new type of nut is easy to slip off the threaded rod during installation, resulting in unstable installation. If the rod is vibrated, the nut will vibrate, causing the nut to loosen and fall off. Utility Model Content
[0004] The technical problem to be solved by the utility model is to provide a new type of nut with an anti-falling structure, which has stable installation and strong anti-falling effect.
[0005] The technical solution adopted by the utility model is a new type of nut with an anti-falling structure, comprising a nut body, wherein threaded connection holes are provided on three sides of the nut body, a circular groove is provided on one end of the threaded connection hole, a hexagonal through hole is provided on the other end of the threaded connection hole, a fastening screw is rotatably connected to the thread in the threaded connection hole, a tightening end is fixed on one end of the fastening screw, a limited circular groove is provided on the other end of the fastening screw, and a hexagonal wedge block is rotatably connected to the limited circular groove.
[0006] As a further solution of the utility model: a threaded connection groove is provided on the side of the nut body, and a threaded groove that is wedged with the threaded connection groove is provided on one side of the hexagonal wedging block to avoid interfering with the normal use of the nut.
[0007] As a further solution of the utility model: a cross tightening groove is provided on one side of the tightening end to facilitate tightening the fastening screw.
[0008] As a further solution of the utility model: the depth of the circular notch is greater than the length of the tightening end, so as to reserve space for tightening the fastening screw.
[0009] As a further solution of the utility model: the hexagonal wedging block slides in the hexagonal through hole to prevent it from rotating.
[0010] As a further solution of the utility model: the outer edges of the nut body are all provided with round chamfers.
[0011] Compared with the prior art, the utility model has the following advantages: the utility model adds a fastening screw structure, opens a threaded hole and a hexagonal through hole on the side of the nut, and drives the hexagonal wedge block to slide in the hexagonal through hole by the fastening screw, thereby strengthening the connection between the nut and the bolt, and can effectively prevent the nut from falling off due to vibration by fastening in three directions.

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0019] The utility model provides a technical solution to solve the existing problems raised in the background technology.
[0020] Combined with Figure 1-3It can be known that the nut includes a nut body 1, and threaded connection holes 1.1 are provided on three sides of the nut body 1. A circular groove 1.2 is provided at one end of the threaded connection hole 1.1, and a hexagonal through hole 1.3 is provided at the other end of the threaded connection hole 1.1. A fastening screw 2 is rotatably connected to the thread in the threaded connection hole 1.1. Rotating the fastening screw 2 can drive the hexagonal wedging block 3 to move. A tightening end 2.1 is fixed at one end of the fastening screw 2, and a limited circular groove 2.2 is provided at the other end of the fastening screw 2. The hexagonal wedging block 3 is rotatably connected in the limited circular groove 2.2, which is convenient for tightening the bolt structure connected to the nut body 1.
[0021] A threaded connection groove 1.4 is provided on the side of the nut body 1, and a threaded groove 3.1 that is wedged with the threaded connection groove 1.4 is provided on one side of the hexagonal wedging block 3 to avoid interfering with the normal use of the nut; a cross tightening groove 2.3 is provided on one side of the tightening end 2.1 to facilitate tightening the fastening screw 2; the depth of the circular groove 1.2 is greater than the length of the tightening end 2.1, leaving space for tightening the fastening screw 2; the hexagonal wedging block 3 slides in the hexagonal through hole 1.3 to prevent it from rotating; and the outer edges of the nut body 1 are all provided with round chamfers.
[0022] The working principle of the present application is as follows: when installing the nut, first disengage the threaded grooves 3.1 on the inner sides of the three hexagonal wedging blocks 3 from the threaded connection grooves 1.4, and then install the bolts. After tightening the nut body 1, use a cross screwdriver to tighten the tightening end 2.1, thereby driving the fastening screw 2 to rotate. The rotation of the fastening screw 2 can drive the hexagonal wedging block 3 to slide in the hexagonal through hole 1.3, so that the threaded groove 3.1 can gradually be wedged with the threaded connection groove 1.4, until the hexagonal wedging blocks 3 in three directions can clamp the connected bolts, and the tightening is completed. The three fastening screws 2 are limited in three directions to effectively prevent the nut body 1 from slipping.
[0023] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
