Abstract
A protective screen for a mine tunnel lamp includes five struts, the five struts are arranged corresponding to assembly holes of end covers of the tunnel lamp, annular lines are evenly arranged outside the five struts and are a circumscribed circle of a pentagon formed by the five struts, a gap is arranged on each annular line between every two adjacent struts, and the connection line of the gaps arranged on the annular lines is parallel to the struts. Due to the adoption of the technical scheme, the mine tunnel lamp protective screen has advantages as follows: the gap is arranged on each annular line between every two adjacent struts, so that the protective screen is provided with a certain elasticity and a certain activity level accordingly, and can be assembled into the two end covers of the mine tunnel lamp more easily.
Description
Technical field
This practicality newly relates to a kind of coal mine roadway lamp wire hood, and tunnel lamp lens cover is protected.
Background technology
Because the particular surroundings in colliery, the tunnel lamp is explosion-proof in order to accomplish, must adopt safer protection, so most of tunnel lamp has all adopted wire hood that cloche is protected, it is quick-fried to prevent that accidental shock from causing the tunnel lamp to lose.Since the structures shape of straight type tunnel lamp the structure of wire hood be cylindrical; The structure of wire hood comprised and was the pillar that regular pentagon arranges and the circumfili of pillar overcoat in the past; Circumfili is complete iron wire ring, all is dead the weldering of the structure of guard during design, and such five pillars are difficult to be assembled in the housing of tunnel lamp end cap in installation process; So the welding requirements to wire hood is very strict, and assembling is relatively more difficult.
Summary of the invention
The purpose of the utility model is to overcome above-mentioned deficiency a kind of coal mine roadway lamp protection network is provided.
The purpose of the utility model realizes through following technical scheme:
A kind of coal mine roadway lamp protection network; Comprise five pillars; The arrangement of five pillars is corresponding with the pilot hole of tunnel lamp end cap, outside five pillars, evenly is provided with circumfili, and circumfili is the pentagonal circumscribed circle that five pillars constitute; On every circumfili between adjacent two pillars, be provided with breach, the breach line that is arranged on the circumfili is parallel with pillar.
Adopt technique scheme; The following advantage of the utility model: owing on every circumfili between adjacent two pillars, be provided with breach; Make protection network that certain elasticity arranged, have certain activity, be more prone to be assembled on the two end cap of coal mine roadway lamp.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
A kind of coal mine roadway lamp protection network as shown in Figure 1; Comprise five pillars 1; The arrangement of five pillars is corresponding with the pilot hole of tunnel lamp end cap, outside five pillars, evenly is provided with circumfili 2, and circumfili 2 is pentagonal circumscribed circles that five pillars constitute; On the every circumfili 2 between adjacent two pillars, be provided with breach 3, the breach line that is arranged on the circumfili is parallel with pillar.The design of breach on the circumfili makes to the utlity model has certain elasticity, is more prone to assembling.
