Abstract
The utility model discloses a kind of safety of sympathetic initiation door, including the internal body for being provided with rotating shaft and the axle bed of the fixed rotating shaft, the body are the integrative-structure of circular arc, and its inner side is provided with spacing pin, and the body includes the gate and wicket connected by the rotating shaft.The utility model uses the safety of sympathetic initiation door of said structure, and the wave energy that withstands shocks power is strong, simple to operate, is easy to reset.
Description
Technical field
Safety of Coal Mine Production technical field is the utility model is related to, more particularly to a kind of safety of sympathetic initiation door.
Background technology
When gas or coal-dust explosion occur for down-hole, explosion proof door can be opened in gas shock caused by blast, so that
Air blast discharges, and plays release effect.The existing explosion proof door of mine is often dished out by powerful shock wave, or nothing after unlatching
Method is resetted, and personnel and equipment are damaged.
Utility model content
The purpose of this utility model is to provide a kind of safety of sympathetic initiation door, and the wave energy that withstands shocks power is strong, simple to operate, is easy to multiple
Position.
To achieve the above object, the utility model provides a kind of safety of sympathetic initiation door, including the internal body for being provided with rotating shaft
With the axle bed of the fixation rotating shaft, the body is the integrative-structure of circular arc, and its inner side is provided with spacing pin, the body bag
Include the gate and wicket connected by the rotating shaft.
Preferably, the axle bed is fixed in wall, and the spacing hole of the fixed spacing pin is provided with the wall.
Preferably, the spacing pin and the spacing hole are L-type.
Preferably, the surrounding of the body is fixed with sealing ring.
Therefore, the utility model uses a kind of safety of sympathetic initiation door of said structure, and the wave energy that withstands shocks power is strong, operation letter
It is single, it is easy to reset.
Below by drawings and examples, the technical solution of the utility model is described in further detail.

Sealing ring.
Embodiment
Embodiment of the present utility model is described further below in conjunction with the accompanying drawings.
Fig. 1 is the front view of the utility model safety of sympathetic initiation door embodiment, and Fig. 2 is that the utility model safety of sympathetic initiation door is implemented
The top view of example, as illustrated, a kind of safety of sympathetic initiation door, includes inside and be provided with the body 1 of rotating shaft 2 and the axle bed of fixed rotating shaft 2
3, axle bed 3 is fixed in wall 7.Body 1 is the integrative-structure of circular arc, including the gate 5 and wicket 6 connected by rotating shaft 2.
Fig. 3 is the schematic diagram of wall spacing hole embodiment in the utility model safety of sympathetic initiation door, as illustrated, in body 1
Side is provided with spacing pin 4, the spacing hole 8 of fixed spacing pin 4 is provided with wall 7, spacing pin 4 and spacing hole 8 are L-type.
Longitudinal schematic diagram in wall upper limit hole is shown in Fig. 2, Fig. 3 is the horizontal schematic diagram in wall upper limit hole, can after overall combination
To show the L-type of spacing hole 8.The surrounding of body 1 is fixed with sealing ring 9, and sealing ring 9 can improve the sealing of body 1.
Below by the specific course of work of the present embodiment, the technical solution of the utility model is done and further retouched in detail
State.
In normal use, spacing pin is fixed on body 1 a kind of safety of sympathetic initiation door, and body 12 can freely turn around the shaft
Dynamic, when there is the severe impact ripples such as blast to occur, body 1 is by impulsive force, and gate 5 is compared to the great efforts that wicket 6 is subject to, greatly
Door 5 is inwardly rotated, due to the integrative-structure of body 1, wicket 6 is turned out by inward force.It is quick-fried due to the rotation of body 1
Shock wave does not produce infringement to body 1 caused by fried.After shock wave, due to the spinfunction of safety of sympathetic initiation door, body 1 is certainly
Dynamic to return to home position, staff can be run away to where safety of sympathetic initiation door.Spacing pin 4 in body 1 is inserted into wall 7
Spacing hole 8 in.Due to the L shape of spacing pin 4 and spacing hole 8, it is necessary to first move in parallel spacing pin 4, then up or
Rotate down so that body 1 is fixed on wall 7.Gate 5 is different from the direction of spacing pin 4 of wicket 6, on corresponding wall 7
The direction of spacing hole 8 it is identical, be inwardly inserted into the L-type front end of spacing pin 4, strengthen the resistance to explosion wave.
Therefore, the utility model uses a kind of safety of sympathetic initiation door of said structure, and the wave energy that withstands shocks power is strong, operation letter
It is single, it is easy to reset.
Finally it should be noted that：Above example is only illustrating the technical solution of the utility model rather than it is limited
System, although the utility model is described in detail with reference to preferred embodiment, one of ordinary skill in the art should manage
Solution：Still the technical solution of the utility model can be modified for it or equivalent substitution, and these are changed or equally replaced
Change the spirit and scope that can not also make amended technical scheme depart from technical solutions of the utility model.
