Abstract
The utility model discloses a small -size plastic housing seal waterproof construction, the charger comprises an upper cover and a lower cover, the hardness of upper cover is greater than the hardness of lower cover, and the below of upper cover is equipped with lower contact surface down, the top of lower cover is equipped with last contact surface up, down contact surface and last contact surface set up relatively, and the lower contact surface sanding treatment of upper cover is equipped with waterproof double -layered line, the last contact surface polishing treatment one -tenth smooth surface of lower cover, in the waterproof double -layered line of upper cover can insert the last contact surface of lower cover, make down contact surface and the inseparable interlock of last contact surface sealed, upper cover fixed knot fits the top of lower cover. In the waterproof double -layered line of upper cover can insert the last contact surface of lower cover, make down contact surface and the inseparable interlock of last contact surface sealed, upper cover fixed knot fits the top of lower cover. So, reach reduce cost, improvement operating efficiency, sealed respond well when being convenient for the maintenance.
Description
Technical field
This utility model relates to small size synthetic resin product shell and seals waterproof technique field, particularly relates to a kind of small-sized
Plastic casing hermetic water-proof structure.
Background technology
For small handheld electronic devices, general volume is little, lightweight, compact conformation, and have is the most out of office
Outer practicality, protected from environmental, this kind equipment usually there is is waterproof requirement, such as Fig. 1 a, Fig. 1 b, figure
Shown in 1c, the most traditional waterproof type is to need the upper cover 10 combined and lower cover 20 junction to adopt at housing
Realize with adding the different modes such as O-ring seal 30 or ultrasonic bond wiring 40 or gluing bonding 50
Case top lid and the sealing of lower cover junction, to reach waterproof purpose.
But these waterproof type technics comparing of the prior art are complicated, operate cumbersome, needing
Time to be keeped in repair the most relatively difficult, and improve product cost.
Therefore, it is necessary to design a kind of new small size synthetic resin housing seal waterproof construction, to solve above-mentioned technology
Problem.
Utility model content
For problem present in background technology, this utility model purpose is to provide and a kind of improves small size synthetic resin shell
Body hermetic water-proof structure, reduce cost, improve operating efficiency, be easy to maintenance while sealing effectiveness good.
The technical solution of the utility model is achieved in that a kind of small size synthetic resin housing seal waterproof construction,
Including upper cover and lower cover, the hardness of described upper cover is more than the hardness of lower cover, under the lower section of upper cover is provided with down
Contact surface, the upper contact surface being arranged over upward of described lower cover, described lower contact surface is relative with upper contact surface
Arranging, the lower contact surface frosted of upper cover processes and is provided with waterproof clamp, and the upper contact surface polishing of lower cover becomes
Shiny surface, the waterproof clamp of described upper cover can be inserted in the upper contact surface of lower cover, make lower contact surface with on contact
Face is closely engaged sealing, and upper cover secure bond is in the top of lower cover.
In technique scheme, described waterproof clamp is zigzag.
In technique scheme, the sawtooth of the centre of described waterproof clamp is more than the sawtooth on both sides.
In technique scheme, the hardness of described upper cover is 2-3 times of lower cover hardness.
This utility model small size synthetic resin housing seal waterproof construction, by contact surface under the upper cover bigger in hardness
Upper frosted processes and arranges waterproof clamp, and the upper contact surface polishing of lower cover simultaneously becomes shiny surface so that on
The waterproof clamp of lid can be inserted in the upper contact surface of lower cover, makes lower contact surface and upper contact surface closely be engaged close
Envelope, upper cover secure bond is in the top of lower cover.So, reduce cost, raising operating efficiency, be easy to
While maintenance, sealing effectiveness is good.
Accompanying drawing explanation
Fig. 1 is waterproof construction schematic diagram in prior art；
Fig. 2 is this utility model upper cover and lower cover assembling pre-structure schematic diagram；
Fig. 3 is structural representation after this utility model upper cover and lower cover assembling.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, to the technical side in this utility model embodiment
Case is clearly and completely described, it is clear that described embodiment is only that this utility model part is implemented
Example rather than whole embodiments.Based on the embodiment in this utility model, those of ordinary skill in the art
The every other embodiment obtained under not making creative work premise, broadly falls into this utility model and protects
The scope protected.
As shown in Figures 2 and 3, a kind of small size synthetic resin housing seal waterproof construction described in the utility model,
Including upper cover 1 and lower cover 2.
The hardness level of described upper cover 1 and lower cover 2 is done differential process so that the hardness of described upper cover 1
Hardness more than lower cover 2.The lower section of upper cover 1 is provided with lower contact surface 11 down, the top of described lower cover 2
Being provided with upper contact surface 21 upward, described lower contact surface 11 and upper contact surface 21 are oppositely arranged, upper cover 1
Lower contact surface 11 frosted process and be provided with waterproof clamp 3, wherein, waterproof clamp is zigzag, and waterproof
The sawtooth of the centre of clamp 3 is more than the sawtooth on both sides.Upper contact surface 21 polishing of lower cover 2 becomes smooth
Face.
When upper cover 1 and lower cover 2 assemble, screw can be relied on to compress, make the waterproof clamp 3 of described upper cover 1
Can be inserted in the upper contact surface 21 of lower cover 2, lower contact surface 11 and upper contact surface 21 are closely engaged and reach
Waterproof sealing, the purpose of protection internal component.The sealing means being arranged such reduces cost, raising
Operating efficiency, be easy to maintenance while sealing effectiveness good.
This utility model small size synthetic resin housing seal waterproof construction, by the upper cover 1 time contact bigger in hardness
On face 11, frosted processes and arranges waterproof clamp 3, the simultaneously upper contact surface 21 polishing Cheng Guang of lower cover 2
Sliding surface so that the waterproof clamp 3 of upper cover 1 can be inserted in the upper contact surface 21 of lower cover 2, makes lower contact surface
11 and upper contact surface 21 be closely engaged sealing, upper cover 1 secure bond is in the top of lower cover 2.So, reach
To reduce cost, improve operating efficiency, be easy to maintenance while sealing effectiveness good.
The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model,
All within spirit of the present utility model and principle, any modification, equivalent substitution and improvement etc. made, all
Within protection domain of the present utility model should be included in.
