Detailed Description

The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. The embodiment is implemented on the premise of the technical solution of the present invention, and a detailed implementation manner and a specific operation process are given, but the scope of the present invention is not limited to the following embodiments.

The embodiment provides a wear jar spare coupling assembling with waterproof function, sectional view is as shown in fig. 1, including first connector 1, second connector 2 and casing 3, wherein first connector 1 is inside to be the cavity 11 that opens downwards, wholly is the cylinder, and the surface of cavity 11 cavity is provided with annular lug 13, one side that 13 bottoms of lug are close to cavity 11 cavity is provided with first annular mounting groove 12, and be provided with second sealing washer 5 in first annular mounting groove 12, casing 3 top accessible second sealing washer 5 is installed in first annular mounting groove 12, be in the bottom of lug 13 after the casing 3 installation promptly. The second connector 2 can be divided into an upper mounting seat 23 and a lower mounting seat 24, and the whole body is in a circular truncated cone structure. The radius of the upper mounting seat 23 is smaller than that of the lower mounting seat 24, wherein the top of the upper mounting seat 23 is provided with a second annular mounting groove 22, the first sealing ring 4 is arranged in the second annular mounting groove 22, and the annular wall formed by the cavity 11 at the bottom of the first connector 1 can be mounted in the second annular mounting groove 22 through the first sealing ring 4.

This mounting method allows the fitting space between the connectors to be located inside, and the fitting space between the first connector 1 and the housing 3 to be located below the projection 13, so that water does not accumulate in the fitting space even if it flows in from above, and excellent water resistance is achieved.

In the present embodiment, the radius of the projection 13 is larger than that of the lower mount 24, further improving the waterproofness of the second annular mount groove 22 in the upper mount 23.
