Abstract
The invention relates to a dust-proof electric control box. The dust-proof electric control box is provided with a box body and a box cover, wherein the upper edge of the box body is uniformly provided with a plurality of notches; four positions, close to bottom corners, at the bottom of the box body are provided with circuit board positioning columns; the top ends of the positioning columns are tips; an r-shaped fixing block is arranged beside each positioning column; an outward bump is arranged on the outer side of the upper edge of the box body; and an inward turned edge corresponding to the bump is arranged on the outer side of the lower edge of the box cover. The dust-proof electric control box has the advantages of high sealing property, simple structure, low cost, practicability and convenience.
Description
Technical field
The present invention relates to electric-controlled box, especially a kind of dustproof electric-controlled box that is used to place circuit board.
Background technology
Now, increasing product all trends towards miniaturization, intellectuality, even the circuit of the original very huge volume that uses can both be realized with a circuit board now.With intellectualizing system, people are placed on circuit board in the electric-controlled box usually, damage to some extent and maybe need to change in case the purpose of doing like this is components and parts, can easily operate efficiently.But, allocation method in the market is directly circuit board to be bolted in the electric-controlled box, bolt is untied when needing replacing or taking-up again, and such problem of bringing is: troublesome poeration, all need circuit board to be taken out at every turn, waste time and energy with bottle opener or other instruments.And lid and box body just simply overlap, and sealing is relatively poor, and not firm, are easy to the circuit board in the electric-controlled box is exposed in the air, so just might influence the running of each several part.
Summary of the invention
The technical problem to be solved in the present invention is: provide a kind of can blocks dust, and take conveniently, dustproof electric-controlled box simple in structure.
The technical solution adopted for the present invention to solve the technical problems is: a kind of dustproof electric-controlled box, have box body and lid, described box body upper edge evenly is provided with a plurality of recesses, the place, four nearly base angles of box body bottom is provided with the circuit board reference column, the top of described reference column is a spur, each reference column is other to be provided with " fore-telling " type fixed block, and the upper edge arranged outside of described box body has outside projection, and the outside of described lid lower edge has and the corresponding inside flange of described projection.
For the ease of the installation of electric-controlled box body, be provided with installing hole at the bottom of the box of the present invention.
Stationarity when guaranteeing that circuit board is installed, fixed block of the present invention is symmetricly set at the bottom of the box.
In order to increase the intensity of circuit board in installation process, can not fracture because of violent collision, be provided with support column between per two fixed blocks of the present invention.
Same, in order to increase the hardness of dustproof electric-controlled box, prevent box and be out of shape that the inboard of described lid four edges is provided with the support chip that supports box body because of extraneous excessive pressure.
The invention has the beneficial effects as follows, solved the defective that exists in the background technology, good airproof performance of the present invention, simple in structure, cost is lower, and practical and convenient.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is the stereochemical structure exploded view of the preferred embodiments of the present invention;
Among the figure: 1, box body; 2, lid; 3, recess; 4, reference column; 5, fixed block; 6, projection; 7, flange; 8, installing hole; 9, support column; 10, support chip.
Embodiment
The present invention is further detailed explanation with preferred embodiment in conjunction with the accompanying drawings now.These accompanying drawings are the schematic diagram of simplification, basic structure of the present invention only is described in a schematic way, so it only show the formation relevant with the present invention.
A kind of dustproof electric-controlled box as shown in Figure 1, have box body 1 and lid 2, described box body 1 upper edge evenly is provided with a plurality of recesses 3, the place, four nearly base angles of box body 1 bottom is provided with circuit board reference column 4, the top of described reference column 4 is a spur, each reference column is other to be provided with " fore-telling " type fixed block 5, and the upper edge arranged outside of described box body 1 has outside projection 6, and the outside of described lid 2 lower edges has and described protruding 6 corresponding inside flange 7.Fixed block 5 is symmetricly set at the bottom of the box, is provided with support column 9 between per two fixed blocks 5, is provided with installing hole 8 at the bottom of the box,
The electric wire that circuit board connected out can pass recess and extend to box body 1 outside, the inboard of lid 2 four edges is provided with the support chip 10 that supports box body, neither can have influence on the sealing of electric-controlled box integral body, also can not cause the interruption of circuit because of extruding, safe ready.
Just the specific embodiment of the present invention of describing in the above specification, various not illustrating is construed as limiting flesh and blood of the present invention, the person of an ordinary skill in the technical field after having read specification can to before described embodiment make an amendment or be out of shape, and do not deviate from essence of an invention and scope.
