Problems solved by technology

Obviously, once the anti-removal nut is installed, it cannot be disassembled
However, the inner core structure of the above-mentioned anti-unloading nut is relatively complicated, and several inclined grooves need to be opened on its outer side, the processing technology is complicated, and the product cost is increased.
At the same time, during the installation process, the needle rollers must first be placed in the slope groove and then installed inside the outer core. Due to the large number of needle rollers, the installation is more difficult
[0004] Other existing anti-unloading nuts also have the defects of many parts and complex production process

Embodiment Construction

[0022] Such as figure 1 As shown, the anti-dismounting nut is installed on the gas pipeline, and the gas meter is connected with the gas pipeline by it.

[0023] The anti-unloading nut includes an inner core 1 and an outer shell 2, and the outer shell 2 is sleeved on the outer side of the inner core 1. Such as figure 2 As shown, the inner surface of the inner core 1 has threads, and the inner core 1 is screwed to the interface of the gas meter through the threads. The outer surface of the inner core 1 is fixedly connected with four evenly distributed elastic sheets 3. In this embodiment, the fixed pin 4 passes through one end of the elastic sheet 3 to be fixedly connected to the inner core 1. See image 3 shown. The other end of the elastic sheet 3 extends outward.

[0024] Such as Figure 4 and Figure 5 As shown, the inner surface of the housing 2 is provided with seven evenly distributed slopes 22 . Slope 22 is made up of straight face 221 and slope 222, sees Figu...

Abstract

The invention provides an anti-dismounting nut, belonging to the field of mechanical technique, comprising an inner core and a shell jacketed outside the inner core, where the inner surface of the inner core has a screw thread, the end surfaces of both the inner core and the shell have stop edges, the inner surface of the shell and the outer surface of the inner core are made with an annular groove each in the same position, a fastening spring is arranged between the two annular grooves, the outer surface is provided with several elastic plates, one end of each elastic plate is fixed on the inner core and the other end extends to a rotating direction of loosening the inner core, the inner surface of the shell is provided with several slopes for stopping the elastic plates. It has simple structure, machining convenience, lower cost, and mounting simplicity.

Description

technical field [0001] The invention belongs to the technical field of machinery, and relates to a fastener, in particular to an anti-unloading nut. Background technique [0002] Nut connections are widely used, such as gas meters and gas pipelines are usually connected by nuts. Because the gas meter is installed in the user's home, in order to prevent illegal gas theft and facilitate the installation of the gas meter, it is necessary to adopt a convenient anti-unloading nut for connection. [0003] Chinese patent 97230082.1 provides a kind of " anti-unloading nut ", and it is made up of inner core and outer core. The inner core is installed in the outer core, and the side surface of the inner core is provided with several inclined grooves along the circumferential direction, and cylindrical needle rollers are arranged between the inclined grooves and the inner side of the outer core. When installing the anti-dismounting nut, turn the outer core along the deep end of the s...
