Abstract
The utility model relates to an explosion-proof work lamp, which mainly solves the problems that the prior explosion-proof work lamp possesses low heat radiation efficiency and short usage life. The explosion-proof work lamp is characterized in that the peripheral of a housing is provided with circular grooves, and forms a heat insulation chamber, a channel is provided in the heat insulation chamber, the heat insulation chamber enables the housing to cooperate with the chamber of a lamp head shield to form an upper chamber and a lower chamber, an illuminant is provided in the lower chamber, the electric appliance element is provided in the upper chamber, the upper chamber and the lower chamber are connected through the channel, and the illuminant and the electric appliance element are connected through an electrical wire board which traverses the channel. The illuminant and the electric appliance element are positioned in different chambers, thus most heat generated by the illuminant can rapidly radiate out, and the problem is prevented that excessive heat radiated by the illuminant flows upward to cause burnout of the parts in the housing such as the electric appliance element. Thermal diffusivity is largely enhanced; the usage life of the product is prolonged; and the advantage is also possessed that the intensity is high.

Relate to a kind of explosion-proof portable lamp at present, illuminator and housing are that enclosure interior is provided with wiring board etc. in a cavity volume, and the wiring board that the heat that illuminator distributes makes easily burns, thereby causes and can not use, and heat dispersion is relatively poor.
This explosion-proof portable lamp in addition, its housing is connected with the screw that passes through of bonnet, under chemical industry, coastal environment, use, screw be corroded easily or swing cause between body and the bonnet loosening even break away from, the tightness step-down, bonding strength has died down, but because intensity not enough, the anti-powerful collision and the impact capacity that are had are lower, in use cause damage easily, greatly reduce service life, causes using, and causes damage to economy.
Summary of the invention
For the shortcoming that overcomes background technology with not enough, the utility model provides a kind of explosion-proof portable lamp, has that thermal diffusivity is strong, long service life and a high advantage of intensity, has solved short, poor radiation and the low problem of intensity in existing explosion-proof portable lamp service life.
The technical solution of the utility model is: a kind of explosion-proof portable lamp, comprise housing, the front end of described housing is provided with lamp holder, described lamp holder comprises Cap casing and illuminator, described illuminator is located at the inside of Cap casing, described enclosure interior is provided with electric elements and electrical wire board, it is characterized in that: described housing periphery is provided with annular groove and constitutes heat-insulation chamber, described heat-insulation chamber inside is provided with passage, described heat-insulation chamber makes housing cooperate with the cavity of Cap casing and forms upper cavity and lower chamber, described illuminator is located in the lower chamber, described electric elements are located in the upper cavity, described upper cavity is connected by passage with lower chamber, and described illuminator is connected by the electrical wire board that passes passage with electric elements.
Further, described upper cavity is cooperated with lower cover by the loam cake of body and forms, and described loam cake is connected by screw with lower cover.
Further, described lower chamber is that Cap casing cooperates formation with the housing bottom.
Further, described housing upper end is provided with by the screw bonnet that is connected, and the housing that is positioned at the screw below is provided with groove, is provided with nut in the described groove, and described nut passes screw and matches with the upper surface of groove.
Further again, described illuminator is LED, and described LED upper end is provided with fin.
Further, described Cap casing is provided with protective cover outward.
The utlity model has following beneficial effect: because illuminator is with in electric elements are in different cavitys, the most of heat that makes illuminator produce can distribute fast, the upwards mobile interior parts of avoiding distributing owing to illuminator such as electric elements of housing that cause of too much heat are burnt, thermal diffusivity has strengthened greatly, thereby has effectively prolonged the service life of product.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the structural representation of another embodiment in the utility model.
Fig. 3 is an outline drawing embodiment illustrated in fig. 2 in the utility model.
Among the figure, housing 1, Cap casing 2, illuminator 3, electric elements 4, electrical wire board 5, annular groove 6, passage 7, upper cavity 8, lower chamber 9, loam cake 10, lower cover 11, screw 12, bonnet 13, groove 14, nut 15, fin 16
The specific embodiment
At accompanying drawing embodiment of the present utility model is described further below:
Shown in figure, this explosion-proof portable lamp, comprise housing 1, the front end of described housing 1 is provided with lamp holder, described lamp holder comprises Cap casing 2 and illuminator 3, described illuminator 3 is located at the inside of Cap casing 2, described housing 1 inside is provided with electric elements 4 and electrical wire board 5, described housing 1 periphery is provided with annular groove 6 and constitutes heat-insulation chamber, described heat-insulation chamber inside is provided with passage 7, described heat-insulation chamber makes housing 1 cooperate with the cavity of Cap casing 2 and forms upper cavity 8 and lower chamber 9, described illuminator 3 is located in the lower chamber 9, described electric elements are located in the upper cavity 8, and described upper cavity 8 is connected by passage 7 with lower chamber 9, and described illuminator 3 is connected by the electrical wire board 5 that passes passage 7 with electric elements 4.According to such scheme, because illuminator 3 is in the different cavitys with electric elements 4, the heat that illuminator produces can distribute fast, upwards mobile interior electric elements 4 parts of avoiding distributing owing to illuminator such as grade of housing that cause of heat are burnt, thermal diffusivity has strengthened greatly, thereby has effectively prolonged the service life of product.
In the utility model, described upper cavity is cooperated with lower cover 11 by the loam cake 10 of body 1 and forms, and described loam cake 10 is connected by screw 12 with lower cover 11.Screw described here 12 adopts stainless steel STS304 materials, has anticorrosive property, and the intensity height, long service life, and upper cavity is set is split type is to be convenient to dismounting, helps checking, the enforcement of measure such as maintenance.
