Abstract

The utility model discloses a housing water-proofing device for a burglar alarm which is used for the motorcycle. The utility model comprises four parts: a surface housing, an elastic rubber cushion ring, an elastic rubber block which is provided with a plurality of independent conducting wire holes in a row, and a bottom housing. Four angles of the sealing ring which is arranged at the convex structure part of the bottom housing and the surface concave structure part of the square housing body are respectively bended inwards. The four angles in the square housing body are made to form spaces with the rest part of the sealing ring, which does not comprise the inward bending lines of the four angles of the sealing ring, four screws can be placed in each space, and the spaces are used for the screws to fix the bottom housing and the surface housing. The elastic sealing rubber cushion ring is placed in the concave structure slot of the surface housing to reinforce the sealing effect.

Description

Burglar alarm mainframe shell water-tight device

Technical field

The utility model patent relates to a kind of burglar alarm mainframe shell water-tight device, specifically is a kind of motorcycle anti-theft alarm main case water-tight device.

Background technology

Because the operational environment of motorcycle is more abominable, and the control circuit of forming by electronic component of dress in its burglar alarm mainframe, so require main case that good water-tight function must be arranged.At present, motorcycle anti-theft alarm main case on the market mainly contains two kinds: as shown in Figure 1, a kind of is to adopt concaveconvex structure to coincide with bound fraction around drain pan 1 and the face-piece 2, realize the water-tight function, and the sealing ring of concaveconvex structure around fixedly four screw holes 3 of drain pan 1 and face-piece 2 are positioned at, its shortcoming is that four screw holes directly communicate with the main frame electronic component, has the problem of screw hole infiltration; As shown in Figure 2, another kind is folder one an elastic caoutchouc packing ring 301 between drain pan 101 and face-piece 201 identical limits, fixed screw holes 401 places the outside of housing, and screw hole 401 need be increased to six, though this structure has solved the seepage problem of screw hole, but increased manufacturing cost, it is complicated and attractive in appearance inadequately that the outward appearance of housing also becomes.

Summary of the invention

The purpose of this utility model is intended to overcome the deficiencies in the prior art, and a kind of novel motorcycle anti-theft alarm main case water-tight device is provided.

The technical scheme that the utility model patent is taked comprises: face-piece, elastic caoutchouc packing ring, form with four parts of elastic block rubber, drain pan in the some separate conductors of row hole, four angles of the sealing ring of the part of tetragonal drain pan male structure of housing and the recessed structure of face-piece are curved inwardly respectively, make the outer part of the interior sweep of four angles of interior four angles of square housing and sealing ring, formation can be placed the space of four screw holes, drain pan for screw stays and face-piece respectively.In the groove of the recessed structure of face-piece, place the elastic packing rubber washer to strengthen sealing effectiveness.

The beneficial effects of the utility model are, fixing four screw holes of drain pan and face-piece are placed outside the sealing ring, again these four screw holes are placed within the housing simultaneously, not only make the outward appearance of product shell simply attractive in appearance, and the reduction manufacturing cost, improved the water-tight function of product greatly.

Embodiment

Below in conjunction with description of drawings embodiment of the present utility model is further elaborated, motorcycle anti-theft alarm main case water-tight device of the present utility model as shown in Figure 4: by face-piece A, elastic caoutchouc packing ring B, form with four parts of elastic block rubber C, drain pan D in a row some separate conductors hole.As shown in Figure 3, elastic caoutchouc packing ring B places in the concave groove 12 of face-piece A, and the Si Jiaochu of face-piece A is equipped with four Nut columns 11, and Nut column 11 is used to connect face-piece A and drain pan D, by locking two housings with the screw hole 16 of drain pan D.On elastic block rubber C, a row some separate conductors hole 13 arranged, inserts lead in the hole in and be connected with the internal host electronic component, then with drain pan D on breach 14 clampings.Place the electronic element circuit plate in the drain pan D, the convex edge 15 on the drain pan D is used for pushing down when face-piece A combines with drain pan D elastic caoutchouc packing ring B and embeds in the concave groove 12, realizes the purpose of water-tight.

Claims
