[specific embodiment]
It is as shown in Figure 1 to Figure 3 a kind of box body sealing structure 100 involved in the utility model comprising cooperate
Case lid 1 and cabinet 2.The case lid 1 is equipped with faying face 10, the cabinet 2 be equipped be coupled to faying face 10 with junction 20, institute
It states case lid 1 and is cooperated with cabinet 2 by faying face 10 and the mating each other with junction 20.In the present embodiment, described
Cabinet 2 is a kind of reduction box casing of electric tool, and the case lid 1 is then the reduction gearbox case lid of connection reduction box casing, i.e.,
The box body sealing structure 100 is preferably the box body sealing structure of reduction gearbox in electric tool.
The box body sealing structure 100 further includes sealing element 3, and the case lid 1 is equipped with the receipts that self-bonding face 10 is recessed inwardly
Appearance portion 11, the sealing element 3 is between case lid 1 and cabinet 2 and is placed in the receiving portion 11 of case lid 1, in the case
Increase leakproofness between lid 1 and cabinet 2.With the development of technology, the reduction gearbox miniaturization of a part of electric tool becomes trend,
And with the miniaturization of reduction gearbox, the case lid and its faying face of reduction gearbox become smaller and become inevitable, cause the sealing element knot on case lid
Structure necessarily becomes smaller and hardness is lower.It is that can be more soft rubber parts with the sealing element 3 in present embodiment,
Make that it is suitable in the wider array of box body sealing structure of range.Therefore the sealing element 3 it is unassembled enter case lid 1 receiving portion 11 when
With certain elastic deformation.
As shown in connection with fig. 5, the sealing ring 31 and the number in 31 circumferential direction of sealing ring that the sealing element 3 includes annular
A lug boss 32.The sealing ring 31 is closed cyclic structure, and it is shaped to the faying face 10 for cooperating the case lid 1
Shape.The lug boss 32 is cylindrical-shaped structure and is set to the week of the sealing ring 31 inwardly；In other embodiments
In, the lug boss 32 may also set up in the outer circumferential of the sealing ring 31.The top surface of the lug boss 32 and sealing ring 31
Top surface be in the same plane, and the lower end of the lug boss 32 protrudes out downwards and exceed sealing ring 31 bottom surface.It is described convex
It plays portion 32 to be arranged according to the elasticity and 10 shape of faying face of sealing element 3, sealing element 3 can be made quickly to install to faying face
On 10, while sealing element 3 also can quickly be installed to faying face 10 in the case where there is certain deflection.
In conjunction with shown in Fig. 4 and Fig. 6, the receiving portion 11 of the case lid 1 includes the receiving portion 12 positioned at the periphery of faying face 10
And the locating slot 13 positioned at the inside of receiving portion 12, described accommodation section 12 are self-bonded face 10 with locating slot 13 and are recessed inwardly, and
The locating slot 13 is connected to described accommodation section 12.The sealing ring 31 of the sealing element 3 is contained in described accommodation section 12, and
The lug boss 32 is placed in the locating slot 13.The top surface of the sealing ring 31 exceeds the faying face of the case lid 1 upwards
10, i.e., the described sealing element 3 is at least partly exposed to the faying face 10 of the case lid 1, when so that the case lid 1 and cabinet 2 being coupled
The faying face 10 with junction 20 in conjunction with and squeeze the sealing element 3 and deform, thus to improve the leakproofness at faying face 10.
The width of the locating slot 13 is greater than the width of receiving portion 12, so that the locating slot 13 is set to the faying face
The width of faying face at 10 is increase accordingly, this design is so that will not influence original case lid while locating slot 13 are arranged
Structural strength at 1 faying face 10.The depth of the locating slot 13 is greater than the depth of receiving portion 12 simultaneously, this design is so that convex
Play that portion 32 is more stable is immobilizated on case lid 1.When the sealing element 3 is assembled to case lid 1, due to 32 length of lug boss compared with
Long and 13 depth of locating slot is deeper, so that the lug boss 32 has more stable fixing after installing locating slot 13, is not easy to loosen；
Then as the fixation of the lug boss 32, part of the sealing ring 31 between two adjacent projections 32 can be easily simple
Segmentation installation positioning in receiving portion 12, be with the sealing element 3 in the case where there is certain deflection, also can quickly pacify
It is filled on faying face 10.
The utility model is not limited to above-mentioned specific embodiment.Those of ordinary skill in the art should be readily understood that
It arrives, under the premise of not departing from the utility model principle and scope, a kind of cabinet for electric tool of the utility model is close
There are also many alternative solutions for seal structure.The protection scope of the utility model is subjected to the contents of the claims.
