Description

Sealed water-proof tail end

Technical Field

The utility model belongs to the technical field of waterproof tail end, specifically sealed waterproof tail end.

Background

The waterproof seal tail end is a basic performance that requires when the special occasion is used to the connector, and this structure mainly uses the sealed product of tail end to ensure the sealing performance of product, but present waterproof seal tail end has some problems, and first leakproofness is relatively poor, can not be fine seal the afterbody of connector, and the second connector inserts waterproof tail end back, and fixed effect is relatively poor, thereby can reduce the leakproofness of waterproof seal tail end to it.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a sealed waterproof tail end to solve the problem that proposes among the above-mentioned background art.

In order to achieve the above object, the utility model provides a following technical scheme:

the waterproof tail end is sealed, and comprises a waterproof tail end shell, first sealing rings, second sealing rings and elastic clamping pieces, wherein a fixing ring plate is arranged on the inner wall of the waterproof tail end shell, the left side surface and the right side surface of the fixing ring plate are fixedly connected with the first sealing rings, the outer surfaces of the two first sealing rings are fixedly connected with the inner wall of the waterproof tail end shell, and the inner walls of the two first sealing rings are in lap joint with the surface of a connector; the right side of the connector is in lap joint with the left side of the second sealing ring.

As a further aspect of the present invention: and a plurality of elastic clamping pieces are uniformly distributed on the inner wall of the waterproof tail end shell.

As a further aspect of the present invention: a plurality of rubber blocks are uniformly distributed on the surface of the elastic clamping piece.

As a further aspect of the present invention: the outer surface of the rubber block is lapped with the outer surface of the connector.

As a further aspect of the present invention: and the right side surface of the second sealing ring is in lap joint with the right side surface of the inner wall of the waterproof tail end shell.

Compared with the prior art, the utility model discloses owing to set up waterproof tail end casing, first sealing washer, the second sealing washer, elasticity fastener and block rubber, make two first sealing washers can carry out waterproof for the first time to the connector, the second sealing washer can carry out waterproof once more to it, and the elasticity fastener can drive the block rubber and fix the connector, through twice sealing treatment great improvement the leakproofness of waterproof tail end casing, and through the great improvement of block rubber and elasticity fastener the fixed efficiency of waterproof tail end casing with the connector, thereby the leakproofness of waterproof tail end casing to the connector has been improved.

Detailed Description

The technical solution of the present patent will be described in further detail with reference to the following embodiments.

Referring to fig. 1-3, the waterproof tail end is sealed, and the waterproof tail end comprises a waterproof tail end shell 1, a first seal ring 4, a second seal ring 7 and an elastic clamping piece 5, wherein a fixed ring plate 3 is arranged on the inner wall of the waterproof tail end shell 1, and the fixed ring plate 3 can fix two first seal rings 4, so that the stability of the two first seal rings 4 is improved, the first seal rings 4 are fixedly connected to the left side surface and the right side surface of the fixed ring plate 3, the outer surfaces of the two first seal rings 4 are fixedly connected with the inner wall of the waterproof tail end shell 1, and the inner walls of the two first seal rings 4 are overlapped with the surface of the connector 2; a plurality of elastic clamping pieces 5 are uniformly distributed on the inner wall of the waterproof tail end shell 1; a plurality of rubber blocks 6 are uniformly distributed on the surface of the elastic clamping piece 5; the outer surface of the rubber block 6 is lapped with the outer surface of the connector 2, and due to the arrangement of the rubber block 6, when the rubber block 6 is contacted with the connector 2, a large friction force can be generated, so that the connector 2 cannot easily move; the right side surface of the connector 2 is lapped with the left side surface of the second sealing ring 7, and the first sealing ring 4 and the second sealing ring 7 are arranged, so that the connector 2 can be sealed twice by the first sealing ring 4 and the second sealing ring 7, and the sealing performance of the waterproof tail end shell 1 to the connector 2 is greatly improved; and the right side surface of the second sealing ring 7 is lapped with the right side surface of the inner wall of the waterproof tail end shell 1.

The utility model discloses a theory of operation is: when the afterbody of connector 2 was carried out waterproof sealing as required, made the staff insert in waterproof tail end casing 1 with the afterbody of connector 2 to pass two first sealing washer 4 in proper order, when the surface of connector 2 contacted with block rubber 6, made elasticity fastener 5 shrink, made the afterbody of connector 2 and the contact of second sealing washer 7, made elasticity fastener 5 fix connector 2.

In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood by those of ordinary skill in the art through specific situations.

Although the preferred embodiments of the present patent have been described in detail, the present patent is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present patent within the knowledge of those skilled in the art.
