Description
Technical field
The utility model belongs to light-controller technical field, relates to a kind of protective cover for extending light-controller useful life.
Background technology
At present, the protective cover of light-controller is all plastic material, and as PC, ABS, PP etc., although plastic material cost is comparatively cheap comparatively speaking, they also exist a lot of shortcoming.Such as, although PC material Heat stability is good, low price, uvioresistant ability is poor; ABS material anti-corrosive properties are poor, and toughness is also poor; PP material is easily out of shape.The protective cover of above-mentioned material in use; often due to self problem; can not prevent ultraviolet direct projection on light-controller, this is unfavorable for the useful life extending light-controller, and the light-controller arranged wherein can cause job insecurity by such environmental effects.
Utility model content
The purpose of this utility model is exactly provide a kind of structure simple to overcome defect that above-mentioned prior art exists, economical and practical, can make the protective cover of light-controller Long-Time Service in worse environment.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of protective cover for extending light-controller useful life, this protective cover comprises case and is arranged on the plastic housing of casing interior for fixing light-controller, the open at one end of described case, the other end has drain pan, the inwall of the uncovered side of described case is provided with multiple grab, described plastic housing is fixed on casing interior by grab, described case is also provided with hollow out window, described plastic housing is provided with the transparent window suitable with hollow out window, described plastic housing inwall is also provided with multiple protruding buckle, in use, described light-controller is fixed on plastic housing by protruding buckle, and be arranged in case by plastic housing.
Described case is truncated cone-shaped ladder case.
Described grab is provided with three altogether, and is circumferentially evenly laid on the inwall of the uncovered side of truncated cone-shaped ladder case.
Described plastic housing is the suitable annular plastics shell of size shape and truncated cone-shaped ladder case.
Described annular plastics shell is fixed on truncated cone-shaped ladder casing interior by grab, and the gap between described annular plastics and truncated cone-shaped ladder case is 1mm.
Described protruding buckle is provided with three altogether, and is circumferentially evenly laid on annular plastics shell inwall.
The outer surface of described case is coated with rust preventive coating.
The material of described case is aluminium alloy or stainless steel.
The material of the utility model case adopts aluminium alloy or stainless steel, and its outer surface can rust prevention by applying liquid material paint or do oxidation processes, effectively can prevent ultraviolet direct projection on light-controller, extend the life-span of light-controller.Simultaneously, the moulding of case is the same with the moulding of plastic housing, its relative aperture plastic housing bore is larger, thus ensure that plastic housing can be loaded into, and the gap of 1mm can be reserved with, and design grab, can ensure that plastic housing landing can not occur after being loaded into, and the moulding of case hollow out window is identical with the transparent window moulding of plastic housing, can ensure that the transparent window of plastic housing can be tipped in.
Compared with prior art, the utility model has following characteristics:
(1) light-controller shell short problem in useful life is solved;
(2) improve the job stability of light-controller;
(3) impact that environmental factor causes light-controller is reduced;
(4) improve fire-proof and explosion-proof grade.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Description of symbols in figure:
1-case, 2-plastic housing, 3-protruding buckle, 4-hollow out window, 5-grab.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
Embodiment 1:
As shown in Figure 1, a kind of protective cover for extending light-controller useful life, this protective cover comprises case 1 and is arranged on the plastic housing 2 of case 1 inside for fixing light-controller, the open at one end of case 1, the other end has drain pan, the inwall of the uncovered side of case 1 is provided with multiple grab 5, it is inner that plastic housing 2 is fixed on case 1 by grab 5, case 1 is also provided with hollow out window 4, plastic housing 2 is provided with the transparent window suitable with hollow out window 4, plastic housing 2 inwall is also provided with multiple protruding buckle 3, in use, light-controller is fixed on plastic housing 2 by protruding buckle 3, and be arranged in case 1 by plastic housing 2.
Wherein, case 1 is truncated cone-shaped ladder case, and grab 5 is provided with three altogether, and is circumferentially evenly laid on the inwall of the uncovered side of truncated cone-shaped ladder case.
