Description

A multiple seal ring

technical field

The utility model belongs to the technical field of sealing of motors and batteries, in particular to a multiple sealing ring.

Background technique

At present, in the sealing of motors and batteries at the output end of the electric control industry, electric motorcycle industry and new energy industry, usually an electric motorcycle controller has multiple cylindrical columns that need to be sealed, but there is only one shell, because the cylindrical column It needs to be fixed on the base plate with screws. When there are multiple cylindrical columns fixed at the same time, there is a tolerance between the cylindrical columns and the cylindrical columns. When the shell is covered, there is often a little error between the center of the hole on the shell and the center of the cylinder.

However, the traditional single transverse sealing product structure currently used is prone to have more sealing on one side and less sealing on the other side, which will lead to seal failure, and when the shell is locked with screws, it requires a large torque to lock, such as the shell. If the strength is not good, cracking often occurs, resulting in substandard products or waste products.

SUMMARY OF THE INVENTION

The purpose of the present invention is to provide multiple sealing rings to solve the above-mentioned problems in the background art.

In order to achieve the above purpose, the present utility model provides the following technical solutions: a multiple sealing ring, comprising a sealing ring body, and a first convex sealing gasket and a second convex sealing gasket of the same size are arranged on the outer surface of the sealing ring body. The first convex gasket and the second convex gasket are arranged up and down, and the cross sections of the first convex gasket and the second convex gasket are both trapezoidal. When the shell is locked, The upper end of the first convex gasket and the second convex gasket are in interference with the shell, and the lower end is in interference with the cylindrical step, so as to improve their sealing performance. , even if one of the seals fails, the other can still act as a good seal. Its cross section is a trapezoidal design with low friction, so that it can be compressed with only a small force.

Preferably, a third convex sealing gasket of the same size is provided between the first convex sealing gasket and the ring opening of the sealing body, and between the second convex sealing gasket and the ring opening of the sealing body and the fourth raised gasket, which can further improve its sealing performance.

Preferably, the cross-sections of the third convex sealing gasket and the fourth convex sealing gasket are semicircular, which is convenient for installation and easy to be compressed.

Preferably, the height of the first raised seal is greater than the height of the third raised seal.

Preferably, the height of the first raised sealing gasket is 1.5-2 mm, and the height of the third raised sealing gasket is 0.2-0.3 mm.

Technical effects and advantages of the present utility model:

1. The utility model adopts multiple sealing design, which completely solves the problem of poor sealing, improves the qualified rate of products, saves labor in installation, and reduces assembly time.

2. The double trapezoidal gasket is used to increase the sealing point and reduce the friction, making the installation more simple and convenient.

3. The use of double semi-circular gaskets is easy to compress, which can further improve its sealing performance.

Detailed ways

The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the implementations. example. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present invention.

Figures 1 to 2 show a specific embodiment of a multiple sealing ring of the present invention: it includes a sealing ring body 1, and the outer surface of the sealing ring body 1 is provided with a first convex seal of the same size Gasket 2 and second convex gasket 3, the first convex gasket 2 and the second convex gasket 3 are arranged up and down, and the first convex gasket 2 and the second convex gasket 3 are The cross-sections are all trapezoidal. When the casing is locked, the upper ends of the first raised gasket 2 and the second raised gasket 3 are in interference with the casing, and the lower ends are in interference with the cylindrical steps, thereby improving their sealing performance. , In the first convex gasket 2 and the second convex gasket 3, even if one of the seals fails, the other can still play a good seal. It can be compressed with very little force; between the first convex gasket 2 and the ring mouth of the sealing body 1, and between the second convex sealing gasket 3 and the ring mouth of the sealing body 1 There are a third convex gasket 4 and a fourth convex gasket 5 of the same size, which can further improve its sealing performance; the cross section of the third convex gasket 4 and the fourth convex gasket 5 is a semicircle shape, easy to install, and easy to compress; the height of the first convex gasket 2 > the height of the third convex gasket 4; the height of the first convex gasket 2 is 2 mm, and the third convex gasket The height of the raised gasket 4 is 0.3 mm.

The utility model completely solves the problem of poor sealing, improves the product qualification rate, solves the problem that the casing needs more force to be completely locked due to errors, and reduces the assembly time.

The applicant also declares that the present utility model will illustrate the implementation method and device structure of the present utility model through the above-mentioned embodiments, but the present utility model is not limited to the above-mentioned embodiments, that is, it does not mean that the present utility model must rely on the above-mentioned method and structure. to be implemented.
