Abstract
The utility model discloses a dustproof and waterproof chassis composed of three parts, i.e., a chassis main body (1), a chassis upper cover (2), and a window (3). The chassis main body (1) is a box-type metal body having filleted corners. A loop of first sealing strip (4) is arranged on the contacting line of the upper end of the chassis main body (1) and the chassis upper cover (2). A loop of second sealing strip (5) is arranged on the contacting face of the window (3) and the chassis upper cover (2). The chassis upper cover (2) and a connecting plate (11) of the chassis main body (1) are connected and fixed through a 180-degree hinge (6). The dustproof and waterproof chassis can achieve an optimal dustproof and waterproof effect, and is firm and stable in connecting mode and convenient in maintenance and operation.
Description
Technical field
The utility model belongs to instrument and meter housing field, particularly relates to a kind of casing with functions of waterproof and dustproof.
Background technology
On market, popular instrument cabinet does not almost reach the dustproof and waterproof requirement now, so when the dustproof and waterproof requirement is arranged, general instrument cabinet all can not satisfy application requirements, therefore the appliance circuit plate usually is placed in the terminal box of dustproof and waterproof, this connector cover is screwed on junction box body, inconvenient inspection operation; A lot of terminal boxes are again without form, and the data of reading instrument demonstration constantly in application process, therefore make troubles to work at the scene.
Summary of the invention
Goal of the invention: invent a kind of not only waterproof dustproof while but also can handled easily and the casing of maintenance instrument, in the useful life of improving instrument, increase work efficiency.
Technical scheme: a kind of dustproof and waterproof casing is comprised of chassis body 1, casing upper cover 2, form 3 three parts; Chassis body 1 is the box type metallic object with fillet, and its upper outside is provided with connecting plate 11; Chassis body 1 upper end contacts the sideline and is provided with circle first sealing strip 4 with casing upper cover 2; Casing upper cover is provided with lockset 21, form set bolt 22, and form 3 is fixed on casing upper cover 2 by form set bolt 22, is provided with circle second sealing strip 5 between form 3 and casing upper cover 2 contact-making surfaces; The connecting plate 11 of casing upper cover 2 and chassis body 1 connects fixing by 180 degree hinges 6, connected mode is solid and reliable, facilitates inspection operation, the detachable repairing;
Described chassis body 1 directly casting or burst is welded;
Described chassis body 1 one sides are provided with cable joint perforate 12;
The decrement maximum of the first sealing strip 4 that described casing uses can reach 6 millimeters, to reach best dustproof and waterproof effect, the operating state of avoiding dust or rainwater to enter casing internal influence interior instrument parts, thereby the useful life of having improved instrument.
Advantage of the present utility model and beneficial effect: the utility model chassis body is after the sealing strip assembling, and the sealing strip overall leveling contacts without the dead angle fully with casing, to reach best dustproof and waterproof effect; It is more solid and reliable and for convenience detach that the chain connection mode of casing upper cover and casing main frame makes the casing upper cover installation in addition.
