Abstract
Disclosed in the utility model is a waterproof and dustproof structure of an upside-down mounting type cabinet. The waterproof and dustproof structure comprises a cabinet body and a cabinet cover plate. A cutting opening is arranged at the cabinet body, wherein the length and the width of the cutting opening are less than the cabinet cover plate; an L-shaped metal frame that is protruded towards the inside of the cabinet is arranged at the outer edge of the cutting opening; and the L-shaped metal frame and the cabinet body are in an integrated mode. An annular boss is arranged at the position, corresponding to the L-shaped metal frame of the cabinet, of the inner surface of a cabinet lower cover plate, wherein the height and the width of the annular boss are less than the depth and the width of the L-shaped metal frame; and the annular boss and the L-shaped metal frame cooperate with each other to form a groove. When water or dust enters the cabinet, the water or the dust is gathered into the groove and is led out directly and downwardly, so that the cabinet can realize the waterproof and dustproof effects with the IP55 level in the upside-down mounting mode.
Description
Technical field
The present invention relates to cabinet water proof and dust proof technical field, be specifically related to a kind of waterproof and dustproof structure of upside-down mounting cabinet.
Background technology
For anti-sealing and dust enter cabinet inside, the electronic product of cabinet inside is produced to ill effect, in cabinet design, conventionally use waterproof and dustproof structure.A kind of waterproof and dustproof structure of casing is disclosed in Chinese utility model patent CN201450677U, referring to Fig. 1, this structure has been opened a cutting openings on machine case body, the length of cutting openings and the wide cabinet cover plate that is all less than, cutting openings outer is provided with a metal frame, metal frame and machine case body are one-body molded, are provided with a circle groove between metal frame outer and machine case body; But because cabinet is upside-down mounting mode, adopt this structure dust and water all can be concentrated on to sealing place, can not arrive the good water proof and dust proof effect that plays.
Utility model content
For the defect of prior art, the utility model proposes a kind of waterproof and dustproof structure of upside-down mounting cabinet, its object is, under casing upside-down mounting state, can keep good water proof and dust proof effect.
To achieve these goals, the technical solution adopted in the utility model is as follows:
A kind of waterproof and dustproof structure of upside-down mounting cabinet, comprise machine case body and cabinet cover plate, it is characterized in that: on machine case body, have a cutting openings, the length of cutting openings and the wide cabinet cover plate that is all less than, cutting openings outer is provided with a L shaped metal frame to cabinet inside projection, and L shaped metal frame and machine case body are one-body molded; At cabinet lower cover inner surface and the L shaped metal frame correspondence position of cabinet, be provided with an annular boss; The height of annular boss and width are all less than the degree of depth and the width of L shaped metal frame, and annular boss coordinates formation groove with L shaped metal frame.
Further, the annular boss inner surface on described cabinet lower cover is provided with a circle sealing ring.
Further, at cabinet lower cover edge, have boring, on L shaped metal frame, relevant position has the screwed hole not boring, by boring and screwed hole in inserting bolt, thereby by cover plate fixing seal on casing.
The beneficial effects of the utility model are:
The waterproof and dustproof structure that the utility model provides, it is at the cabinet cutting openings place of upside-down mounting, on lower cover, the L shaped metal frame of annular boss and machine case body forms concave structure, when cabinet is met water chance dirt, can successfully water and dirt be gathered in groove, and it is directly derived downwards, make cabinet reach the waterproof and dustproof effect of IP55 grade.
Further, the annular boss inner surface on case lower cover is provided with sealing ring, strengthens sealing property, has improved dustproof and waterproof effect.
Further, at cabinet lower cover edge, have boring, on L shaped metal frame, relevant position has the screwed hole not boring, by boring and screwed hole coordinated the encapsulation of cover plate to casing, simple in structure, easy to operate.
Accompanying drawing explanation
Fig. 1 is prior art casing structure schematic diagram;
Fig. 2 is the utility model casing structure schematic diagram;
Fig. 3 is the utility model casing structure cross-sectional view.
Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
The structure of the water proof and dust proof of upside-down mounting cabinet, referring to Fig. 2 and Fig. 3, comprises machine case body 1, rectangular cabinet lower cover 2, has cutting openings 3 on machine case body 1, is also rectangle, but its long and wide length that is all less than cabinet cover plate and wide.Along the periphery of cutting openings, be provided with " L " shape metal frame 4 to cabinet inside projection, L shaped metal frame 4 is one-body molded with machine case body 1; Cabinet lower cover inner surface and L shaped metal frame 4 correspondence positions are provided with an annular boss 5; The height of boss and width are all less than the degree of depth and the width of L shaped metal frame.Lower cover annular boss 5 forms groove with the L shaped metal frame 4 of machine case body, and when cabinet is met water chance dirt, groove can successfully be gathered in water and dirt in Baltimore groove, and it is directly derived downwards.
At cabinet lower cover edge, be provided with some boring 6, on L shaped metal frame, relevant position also has the screwed hole 7 not boring.Lower cover, by after machine case body closure, can utilize boring by lower cover fixing seal.
Those skilled in the art will readily understand; the foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection range of the present utility model.
