Abstract

The utility model discloses a double-layer water-proof casing which comprises a main casing which is provided with a first peripheral wall and an end surface, a casing cover with a second peripheral wall, a first water-proof strip arranged in a first groove and a second water-proof strip arranged in a second groove, wherein the end surface is provided with the first groove, and the second peripheral wall is provided with the second groove, and is sheathed at the external side of the first peripheral wall. The utility model can solve the problem of poor waterproof efficiency of the casing in the prior art, and the tightly waterproof effect can be obtained.

Description

The double-layer waterproof case

The utility model relates to a kind of double-layer waterproof case, particularly a kind of waterproof case that is used on the waterproof computer.

The waterproof computer generally is used for industrial uses such as factory, because therefore its severe operational environment needs design to make its housing have water-proof function, enters in the housing to prevent extraneous liquid.

Waterproof case of the prior art is shown in Fig. 1 a and 1b, and wherein Fig. 1 a is the profile of waterproof case, and Fig. 1 b is the decomposing schematic representation of waterproof case.

Waterproof case of the prior art mainly is made of a upper shell 20, a lower house 10 and a waterproof bar 30, has a groove 11 on the lower house 10, and waterproof bar 30 promptly is arranged in the groove 11 of lower house 10.

Upper shell 20 and lower house 10 also are respectively equipped with a plurality of

perforation

21,22 and

screw

12,13, when desire during with 10 combinations of upper shell 20 and lower house, by

screw

41,42 pass perforation 21, screw 12 in regular turn and bore a hole 22, screw 13, and with upper shell 20 and lower house 10 combinations, waterproof bar 30 is squeezed at this moment, and in

upper shell

20 and 10 functions of giving full play to waterproof of lower house.

Therefore above-mentioned design when running into upper shell 20 or lower house 10 distortion, promptly has the bad problem of waterproof and produces owing to have only one protection.

In order to address the above problem, the purpose of this utility model is to provide a kind of double-layer waterproof case, and it can provide the double shield of waterproof computer on the waterproof effect.

The purpose of this utility model is achieved through the following technical solutions, and a kind of double-layer waterproof case is provided, and it comprises: the main casing with first perisporium and end face; Cap with second perisporium, and second perisporium is sheathed on first perisporium outside; Be arranged at one first waterproof bar between end face and the cap; And be arranged at one second waterproof bar between second perisporium and first perisporium.

In the utility model, end face is provided with first groove again, in order to the first waterproof bar to be set.

In the utility model, second perisporium is provided with second groove again, in order to the second waterproof bar to be set.

In the utility model, end face is provided with at least one screw again, and is provided with through hole corresponding to screw at cap.

In the utility model, also be provided with at least one bolt again, be located at screw in order to revolve, and then cap is incorporated into main casing via through hole.

In the utility model, provide a kind of double-layer waterproof case again, it comprises: have a main casing of first perisporium and end face, and end face is provided with first groove; Have a cap of second perisporium, second perisporium is provided with second groove, and second perisporium is sheathed on first perisporium outside; Be arranged at one first waterproof bar of first groove; And the one second waterproof bar that is arranged at second groove.

The utility model has the advantages that,, so can make waterproof case be subjected to dual protection, thereby make water-proof function better because the utility model adds a waterproof bar on cap.

Existing conjunction with figs. illustrates embodiment of the present utility model.

Fig. 1 a is the profile of the waterproof case of prior art;

Fig. 1 b is the decomposing schematic representation of the waterproof case of prior art;

Fig. 2 a is the profile of waterproof case of the present utility model; And

Fig. 2 b is the decomposing schematic representation of waterproof case of the present utility model.

Below with reference to Fig. 2 a, 2b waterproof case of the present utility model is described.

As shown in the figure, waterproof case of the present utility model is made of a cap 60, a main casing 50, one first waterproof bar 70 and one second waterproof bar 80, wherein main casing 50 has first perisporium 55 and end face 54, cap 60 has second perisporium 64, and second perisporium 64 can be sheathed on first perisporium, 55 outsides of main casing 50.

Have one first groove 51 and one second groove 61 on the end face 54 and second perisporium 64 respectively, and the first waterproof bar 70 and the second waterproof bar 80 are arranged at respectively in second groove 61 of first groove 51 of main casing 50 and cap 60.

Cap 60 and main casing 50 are respectively equipped with a plurality of through

holes

62,63 and the

screw

52,53 corresponding with through hole, when desire during with 50 combinations of cap 60 and main casing, pass through hole 62, screw 52 and through hole 64, butterfly hole 53 in regular turn by

bolt

91,92, and can be with cap 60 and main casing 50 combinations, at this moment, the first waterproof bar 70 and the second waterproof bar 80 are squeezed respectively, thereby in

cap

60 and 50 functions of giving full play to waterproof of main casing.

Above-mentioned waterproof bar can be made by the material of waterproof such as rubber and elastically deformable.

Though the utility model with preferred embodiment openly as above; but it is not in order to restriction the utility model; any technical staff who knows this technology; in not breaking away from spirit and scope of the present utility model; still can do to change and retouching, therefore protection range of the present utility model is when being defined by accompanying claim.
