Description
Technical field
The utility model relates to a kind of explosion-proof camera shooting instrument, belongs to anti-explosion surveillance technical field.
Background technology
The international mainstream mode of current explosion-proof camera shooting instrument is flame-proof type, is to be placed in special shell by the common camera of routine, and this shell has the effect kept apart by explosive mixture outside the spark of electric component generation in shell and electric arc and shell.And explosion-proof function is mainly reflected in the syndeton of housing and diffuser, if connection sealing can be poor, just cannot intercept spark and electric arc, the syndeton of existing housing and diffuser adopts bonding way usually, and sealing effectiveness is poor, and explosion-proof effect is not good.
Summary of the invention
The purpose of this utility model is to provide a kind of housing and diffuser good sealing effect, the explosion-proof camera shooting instrument that explosion-proof effect is good.
In order to achieve the above object, the technical solution of the utility model is: a kind of explosion-proof camera shooting instrument, comprise housing, diffuser and video camera, diffuser is fixedly connected with housing, video camera is fixed in housing, also comprise upper cover, cushion pad, pressing plate and clamping screw, bottom plate and upper mounted plate is also fixedly connected with in described housing, the bottom of video camera is fixedly connected with bottom plate, top is fixedly connected with upper mounted plate, described diffuser is provided with outside sealing flange, the T-shaped structure of cross section of upper cover, and the top of upper cover is bonding with the sealing flange of diffuser, bottom is fixedly connected with housing by clamping screw, pressing plate is placed on upper mounted plate, cushion pad is located between the sealing flange of diffuser and pressing plate.
Described upper cover adopts epoxide-resin glue bonding with the sealing flange of diffuser.
After adopting said structure, the utility model is owing to adopting the upper cover of T-shaped structure, the top of upper cover is bonding with the sealing flange of diffuser, bottom is fixedly connected with housing by clamping screw, and upper cover is by compressing the sealing flange of diffuser, sealing is conveniently pressed on pressing plate simultaneously, compress firmly, the upper cover of T-shaped structure has the effect of labyrinth seal, therefore good sealing effect, and explosion-proof effect is also improved.
Accompanying drawing explanation
Fig. 1 is structure cutaway view of the present utility model.
Embodiment
The embodiment provided below in conjunction with accompanying drawing is described in further detail the utility model.
Shown in Figure 1, a kind of explosion-proof camera shooting instrument, comprise housing 1, diffuser 2 and video camera 3, diffuser 2 is fixedly connected with housing 1, video camera 3 is fixed in housing 1, also comprise upper cover 4, cushion pad 5, pressing plate 6 and clamping screw 10, bottom plate 7 and upper mounted plate 8 is also fixedly connected with in described housing 1, the bottom of video camera 3 is fixedly connected with bottom plate 7, top is fixedly connected with upper mounted plate 8, described diffuser 2 is provided with outside sealing flange 2-1, the T-shaped structure of cross section of upper cover 4, and the top of upper cover 4 adopts epoxide-resin glue bonding with the sealing flange 2-1 of diffuser 2, bottom is fixedly connected with housing 1 by clamping screw 10, pressing plate 6 is placed on upper mounted plate 8, cushion pad 5 is located between the sealing flange 2-1 of diffuser 2 and pressing plate 6.
Shown in Figure 1, when the utility model is installed, be fixedly connected with bottom plate 7 bottom of video camera 3, top is fixedly connected with upper mounted plate 8, fixation.Pressing plate 6 is placed on upper mounted plate 8, cushion pad 5 is placed on pressing plate 6, play cushioning effect, and the sealing flange 2-1 of diffuser 2 is placed on cushion pad 5, upper cover 4 is pressed on the sealing flange 2-1 of diffuser 2, and bonding by epoxide-resin glue, and the bottom of upper cover 4 is locked by clamping screw 10 and housing 1.The utility model upper cover 4 adopts T-shaped structure, and have the effect of labyrinth seal, therefore good sealing effect, explosion-proof effect is also improved.
Above-described is only preferred implementation of the present utility model; it should be pointed out that for the person of ordinary skill of the art, under the prerequisite not departing from the utility model creation design; can also make some distortion and improvement, these all belong to protection range of the present utility model.
