Abstract
The utility model relates to a casing waterproof sealing structure, including epitheca, inferior valve and be located the epitheca and the inferior valve between the seal, its characterized in that, epitheca and inferior valve all have a casing that the cross -section is " concave " style of calligraphy the aperture edge of epitheca and inferior valve all extends there is the boss, the boss of epitheca and inferior valve is laminated each other, epitheca and inferior valve form a confined space jointly, wherein, the seal is " 8 " style of calligraphy, the last mediate difference of circle down inscribe in the epitheca and the inferior valve of seal. The utility model discloses line contact when sealed, triple guarantees, it is sealed effectual, non - sealing region has a great space between sealing strip and the casing, and sealing strip bounce -back surplus is big, between the seal shell locking force do not need too big, the sealing strip not also easy elastic deformation became invalid, simple structure, preparation be convenient, with low costs, can satisfy the sealed demand of complicated casing appearance, simple to operate does not have the direction, the easy realization is standardized.
Description
Technical field
The utility model relates to a kind of housing seal field, particularly simple, the effective housing waterproof sealing structure of a kind of structure.
Background technology
Hand-held three anti-terminal equipment housing seals are emphasis is also a difficult point, as shown in Figure 1, common scheme is placed in female shell (housing of band seal groove) with sealing strip that is block or sheet, the boss of public shell (housing of band seal boss) is pressed on sealing strip, coupling mechanism force by two housings compresses, thus reaches the object of sealing.
Traditional encapsulation scheme has following several shortcoming: 1. sealing strip easily lost efficacy, when main cause has sealing strip to seal face contact the unbalance stress that brings and coupling mechanism force not enough etc.; 2. the version of sealing strip is varied, and versatility is bad, not easily realizes standardization, and cost is high; 3. the coupling mechanism force between housing requires larger, easily causes the stress of structure concentrate thus occur local damage.
Utility model content
For solving the problems of the technologies described above, the purpose of this utility model is: provide a kind of housing waterproof sealing structure, it adopts " 8 " font cross section sealing bar, solves sealing, simplicity and standardization three problems simultaneously.
For achieving the above object, the technical scheme that the utility model adopts is:
A kind of housing waterproof sealing structure, comprise upper casing, lower casing and the seal between upper casing and lower casing, described upper casing and lower casing all have the housing of cross section in " recessed " font, all boss is extended with in the faucal edge of described upper casing and lower casing, the boss of described upper casing and lower casing is bonded to each other, and described upper casing and lower casing form a seal cavity jointly, wherein, described seal is the elastic sealing strip in " 8 " font, and upper circle and the lower circle of described seal are inscribed within upper casing and lower casing respectively.
Described housing waterproof sealing structure, the waist of described seal and between upper casing and the housing of lower casing, there is gap.
Described housing waterproof sealing structure, the boss of described upper casing and lower casing is fixed by lock-screw.
Compared with prior art, adopt the utility model has the advantage of of technique scheme: 1. linear contact lay during sealing, triple guarantee, good sealing effect; 2. between seal and housing, non-sealed regions has larger space, and seal bounce-back surplus is large, and between seal casinghousing, coupling mechanism force does not need too large, and seal is also easily strain inefficacy not; 3. structure is simple, easy to make, and cost is low, can meet more complicated housing profile sealing demand; 4. easy for installation, there is no direction; 5. easily realize standardization.
Accompanying drawing explanation
Fig. 1 is prior art middle shell waterproof sealing structure schematic diagram;
Fig. 2 is the utility model housing waterproof sealing structure schematic diagram.
Description of reference numerals: 1-seal; 2-upper casing (public shell); 3-lower casing (female shell); 4-lock-screw; 5-gap.
Embodiment
Further describe the utility model below in conjunction with specific embodiments and the drawings, advantage and disadvantage of the present utility model will be more clear along with description.
As shown in Figure 2, for a kind of housing waterproof sealing structure schematic diagram of the present utility model, comprise upper casing 2, lower casing 3 and the seal between upper casing 2 and lower casing 31, described upper casing 2 and lower casing 3 all have the housing of cross section in " recessed " font, all boss is extended with in the faucal edge of described upper casing 2 and lower casing 3, the boss of described upper casing 2 and lower casing 3 is bonded to each other, described upper casing 2 and lower casing 3 form a seal cavity jointly, wherein, described seal 1 is in " 8 " font, and upper circle and the lower circle of described seal 1 are inscribed within upper casing 2 and lower casing 3 respectively.Between the waist of described seal 1 and the housing of upper casing 2 and lower casing 3, there is gap 5.The boss of described upper casing 2 and lower casing 3 is fixed by lock-screw 4.
In sum, from above content, the utility model has the advantage of: 1. linear contact lay during sealing, triple guarantee, good sealing effect; 2. between the housing of seal 1 and upper casing 2 and lower casing 3, non-sealed regions has larger space, and seal 1 surplus that rebounds is large, and between seal casinghousing, coupling mechanism force does not need too large, seal 1 not also easily strain lost efficacy; 3. structure is simple, easy to make, and cost is low, can meet more complicated housing profile sealing demand; 4. easy for installation, there is no direction; 5. easily realize standardization.
Above explanation and embodiment are only exemplary, do not form any restriction to scope of the present utility model.It will be understood by those skilled in the art that and do not departing under spirit and scope of the present utility model and can modify to the details of technical solutions of the utility model and form or replace, but these amendments and replacement all fall in protection range of the present utility model.
Claims (3)
1. a housing waterproof sealing structure, comprise upper casing, lower casing and the seal between upper casing and lower casing, it is characterized in that, described upper casing and lower casing all have the housing of cross section in " recessed " font, all boss is extended with in the faucal edge of described upper casing and lower casing, the boss of described upper casing and lower casing is bonded to each other, described upper casing and lower casing form a seal cavity jointly, wherein, described seal is the elastic sealing strip in " 8 " font, and upper circle and the lower circle of described seal are inscribed within upper casing and lower casing respectively.
2. housing waterproof sealing structure according to claim 1, is characterized in that, the waist of described seal and have gap between upper casing and the housing of lower casing.
