Abstract

The utility model relates to an explosion-isolation all-weather camera protective cover, which comprises a sun shade (2), a casing body (5), an end cover (9), a back cover (6), a pendulum shaft (4), a rain wiper (10) and transparent glass (1), wherein, the rain wiper (10) is installed on the pendulum shaft (4), and the transparent glass (1) is installed on the end cover (9). The utility model is characterized in that the transparent glass (1) is convex in shape, the convex surface (1-1) of which is on a same flat surface with the outer end surface of the end cover (9), and the rubber part (10-1) of the rain wiper (10) is contacted with the convex surface (1-1). Through the improvement on the structure of the transparent glass of the utility model, the pendulum angle of the rain wiper is large, no dead angle exists, and the effect of wiping rain is good. The utility model is designed according to an explosion proof requirement, thus having explosion proof performance, and being suitable for being used in industrial and mining places under bad environment.

Description

The round-the-clock video camera guard shield of flame proof

Technical field

The utility model relates to the round-the-clock video camera guard shield of a kind of flame proof, is a kind of protective cover that is specifically designed to dress video camera and camera lens do supervision usefulness, requires dustproof, waterproof, is used for outdoor environment.

Background technology

The video camera guard shield of outdoor use exists following deficiency in the market: its clear glass is generally planar structure, assembling back glass surface to recurve in the end cap outer face, when whole wiper blade rubbers partly drops on the glass surface swing, owing to be subjected to the restriction of end cap, its pivot angle is little, have the dead angle, thus wiper blow the rain weak effect.

Summary of the invention

The purpose of this utility model provides the round-the-clock video camera guard shield of a kind of flame proof, and its wiper pivot angle is big, effective.

The technical scheme that realizes above-mentioned purpose is: the round-the-clock video camera guard shield of a kind of flame proof, comprise sky shade, housing, end cap, bonnet, balance staff, wiper and clear glass, wiper is installed on the balance staff, clear glass is installed on the end cap, clear glass is convex, and the outer face of its convex surface and end cap at grade, and the rubber part of wiper contacts with this convex surface.

After adopting technique scheme, clear glass is convex, and the outer face of the convex surface of clear glass and end cap at grade, the rubber part of wiper just can not be subjected to the restriction of end cap again following wiper swing when blowing rain, and pivot angle is big, and there is not the dead angle, strengthened and blown the rain effect.

Description of drawings

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the structural representation of clear glass of the present utility model.

Embodiment

Below in conjunction with drawings and Examples the utility model is described in further detail.

Shown in Fig. 1～2, the round-the-clock video camera guard shield of a kind of flame proof, comprise sky shade 2, housing 5, end cap 9, bonnet 6, balance staff 4, wiper 10 and clear glass 1, wiper 10 is installed on the balance staff 4, clear glass 1 is pressed on the end cap 9 by pressing plate 3 and housing screw 8, clear glass 1 is convex, and the outer face of its convex surface 1-1 and end cap 9 at grade, and the rubber part 10-1 of wiper 10 contacts with this convex surface 1-1.Clear glass 1 adopts tempered glass, to increase the intensity of clear glass 1.

As shown in Figure 1, housing 5 is provided with lead wire outlet 7, is convenient to wiring.

During the utility model work, start the motor in the housing 5, motor makes balance staff 4 swings by gear train, and balance staff 4 drives wiper 10 swings, and the rubber part 10-1 of wiper 10 promptly swings on the convex surface 1-1 of clear glass 1, plays the rain effect of blowing.Motor can be by the manual control start-stop.

Housing 5 of the present utility model, is suitable for the abominable industrial and mineral place of environment and uses so this product is a flame-proof type by the requirement of explosion proof design.

Claims

1, the round-the-clock video camera guard shield of a kind of flame proof, comprise sky shade (2), housing (5), end cap (9), bonnet (6), balance staff (4), wiper (10) and clear glass (1), wiper (10) is installed on the balance staff (4), clear glass (1) is installed on the end cap (9), it is characterized in that: clear glass (1) is convex, and the outer face of its convex surface (1-1) and end cap (9) at grade, and the rubber part (10-1) of wiper (10) contacts with this convex surface (1-1).

2, the round-the-clock video camera guard shield of flame proof according to claim 1 is characterized in that: described clear glass (1) is a tempered glass.
