Problems solved by technology

[0002] When installing and using distribution boxes or similar electrical equipment boxes, threaded joints are often used for fixed installation, such as screws, bolts, etc., and spring washers and lock washers are often used in conjunction with threaded joints , flat washers and other components, these components are not suitable for management and easy to scatter
For example, when using screws to install and fix the surface cover or guide rail of the distribution box, components such as screws or flat washers are easy to scatter during on-site installation or disassembly, are difficult to distinguish, and may even be lost. There are certain security risks

Embodiment Construction

[0051] In order to have a clearer understanding of the technical features, purposes and effects of the invention, the specific implementation manners of the present invention will now be described with reference to the accompanying drawings, in which the same reference numerals represent the same parts.

[0052] Such as figure 1 In the prior art shown in the anti-falling device used for connecting bolts and washers of frequently disassembled plates of construction machinery, it can be seen that, on the one hand, the device is relatively complicated, requiring the cooperation of two parts, the retaining ring 93 and the large flat washer 94 Only use can achieve the effect of anti-dropping, and on the other hand, the retaining ring 93 can only be fixed on a certain position on the bolt 92, and in the installation or dismounting process, the retaining ring 93 cannot rotate on the thread of the bolt 92 and produce The relative displacement between the retaining ring 93 and the reta...

Abstract

The invention provides a gasket, which can be spirally sleeved on a threaded spinner, and under the action of an external rotating force, a part (contacted with the threaded spinner) of the gasket can be deformed, therefore, the gasket is provided with a thread matched with a thread of the threaded spinner. The invention also provides a fixing device which comprises a threaded spinner and a gasket part, wherein the threaded spinner is spirally fixed on a component, the gasket part is spirally sleeved on the threaded spinner, a part (contacted with the threaded spinner) of the gasket is provided with a thread matched with a thread of the threaded spinner, and the thread of the gasket is formed by that a gasket is spirally sleeved on the threaded spinner and then acted by an external rotating force. The invention also provides a distribution box using the fixing device. As the gasket part is spirally engaged with the threaded spinner, a situation that the threaded spinner and the gasket part are always arranged together and not lost and separated can be ensured.

Description

technical field [0001] The present invention relates to a gasket, and also relates to a fixing device comprising a threaded screw part that can be screwed and fixed on a component, and a distribution box using the fixing device. Background technique [0002] When installing and using distribution boxes or similar electrical equipment boxes, threaded joints are often used for fixed installation, such as screws, bolts, etc., and spring washers and lock washers are often used in conjunction with threaded joints , flat washers and other components, these components are not suitable for management and are easy to scatter. For example, when using screws to install and fix the surface cover or guide rail of the distribution box, components such as screws or flat washers are easy to scatter during on-site installation or disassembly, are difficult to distinguish, and may even be lost. There are certain security risks. [0003] Such as figure 1 As shown, in the prior art, there is...
