Problems solved by technology

[0007] Aiming at the deficiencies of the prior art, the object of the present invention is to provide an anti-loosening bolt assembly, which is intended to solve the problem of existing nuts and bolts being connected to connectors. When a certain vibration occurs, it is easy to produce The technical problem of loose connection; through this scheme, the nut and bolt fastening connection structure can be effectively prevented from loosening, thereby ensuring the stable and safe operation of the connection structure and even the entire device. At the same time, the production accuracy is low, and the processing is convenient and simple

Embodiment 1

[0028] This embodiment is a connection structure of anti-loosening bolts, such as Figure 1-Figure 6 as shown, figure 1 is the three-dimensional structure diagram of the connection structure under one viewing angle, figure 2 is the three-dimensional structure diagram of the connection structure under another viewing angle, image 3is the front view of the connection structure, Figure 4 for image 3 The B-B sectional view, Figure 5 is the three-dimensional structure diagram of the locking nut in the connection structure, Figure 6 It is a three-dimensional structure diagram of the locking washer in the connection structure. The connection structure of the anti-loosening bolt includes a locking bolt 1, a locking washer 2 and a locking nut 3. The locking bolt 1 is threaded with a locking nut 3, and a locking washer 2 and a locking nut 3 are arranged between the locking bolt 1 and the locking nut 3. Fitted with the lock washer 2, wherein the lock bolt 1 has a lock groove ...

Embodiment 2

[0031] This embodiment is also a connection structure of anti-loosening bolts, which is similar to the above-mentioned connection structure, except that the compression spring 25 is changed to an ordinary spring, so that the pulling and rebounding effect of the locking block 24 is relatively poor, but it does not It affects its use; at the same time, in this embodiment, the raised wall 22 is only distributed on the outer edge of the locking washer 2, that is, the raised wall 22 is only provided on a certain part of the outer edge of the locking washer 2, and the raised wall 22 is raised there. The wall 22 has a wall hole 23, and a locking block 24 and a common spring are provided, so that the effect and function of the structure can be fully realized, but the overall strength of the locking washer 2 is not as high as that of the whole ring, but it does not affect the structure at all. use and stability.

Abstract

The invention discloses a check bolt assembly. The check bolt assembly is aimed at solving the technical problem that when certain vibration happens, the connection structure between connecting objects which is formed by existing nuts and bolts easily looses. The check bolt assembly comprises a locking bolt, a locking gasket and a locking nut, wherein the locking bolt is in threaded connection with the locking nut; the locking gasket is arranged between the locking bolt and the locking nut; the locking nut is fit to the locking gasket; a locking groove is vertically formed in a threaded rod part of the locking bolt in a through manner; locking teeth II for positioning and locking are arranged at the bottom of the locking nut; an inner ring of the locking gasket is provided with a locking bulge which is matched with the locking groove and can slide vertically in the locking groove; and a bulge wall is arranged on the outer edge part of the locking gasket. According to the technical scheme, the effective locking of the nut and bolt fastening connection structure is realized, and the stable and safe operation of the connection structure and even the entire device is ensured; and meanwhile, the requirement on the production precision is low, and the processing is convenient and simple.

Description

technical field [0001] The invention belongs to the structure of mechanical parts, in particular to an anti-loosening bolt assembly. Background technique [0002] A nut is also a nut, which is a part that is screwed together with a bolt or a screw to tightly connect mechanical equipment. Or the outside of the screw is connected with the thread of the same specification, which is a necessary component for all manufacturing machinery. [0003] In daily life and relatively stable mechanical equipment, the connection between nuts and bolts can be said to be very stable and safe. In vibrating equipment, the situation may be more complicated, because the connection between nuts and bolts is generally rigid. When the connection structure is in a certain amplitude and frequency of vibration, the connection structure will resonate, and because the connection structure There may be differences in the vibration frequencies of the connecting parts themselves, resulting in a difference...
