Technical Field
The invention relates to the field of test devices for detecting explosion-proof performance, in particular to a skin-soaking puncture rod.
Background
The safety of a bulb in use in an explosive atmosphere is determined by two aspects: first, the circuit spark of the bulb contact part; secondly, after the bulb skin breaks up, the burning filament is ignited by exposure to the heat of the explosive gas. Either or both of these are dangerous for the particular explosive gas mixture. Through experimental studies and analysis, for small capacity bulbs, there is mainly the risk of the glowing filament being exposed to explosive gases after breaking of the bulb envelope and detonating the latter.
In order to test whether a burning filament will ignite an explosive gas in an explosive gas mixture after the bulb envelope has been broken, it is desirable to design a bulb envelope puncturing rod.

The invention aims to provide a bulb skin puncture rod which is suitable for breaking bulb skin of a bulb, has high control precision and does not break filaments.
The invention is realized by the following technical scheme: a bubble skin puncture rod comprises a supporting seat, a linear bearing penetrating through the supporting seat and fixed in the supporting seat, and a puncture rod sleeve fixed in an inner ring of the linear bearing.
The two ends of the puncture rod sleeve extend out of the linear bearing respectively, a puncture rod is fixed in the puncture rod sleeve above the supporting seat, a nut is in threaded fit with the top of the puncture rod, a rod tip is in threaded fit with the top of the nut, the rod tip comprises a cylinder in threaded fit with the nut and a cone integrally formed with the cylinder, a return spring is sleeved on the puncture rod sleeve below the supporting seat, and a spring seat matched with the return spring in a stop position is arranged at the end part of the puncture rod sleeve below the return spring.
As a further improvement of the technical scheme of the invention, a ball seat is arranged below the spring seat, a ball is arranged in the ball seat in a rolling way, the ball extends out of the ball seat and is in rolling fit with a rotary table rotatably arranged below the supporting seat, and a cushion block matched with the ball rolling support is arranged on the rotary table positioned on the ball rolling path.
As a further improvement of the technical scheme of the invention, the upper surface of the cushion block along the rolling path of the ball is of a cambered surface structure.
As a further improvement of the technical scheme of the invention, the cushion block along the rolling path of the ball is of an isosceles triangular column structure, and the vertex angle of the isosceles triangular column is of a round corner structure.
According to the bulb skin puncture rod, the rod tip and the puncture rod are of a separated design, the distance from the rod tip to the bulb skin can be adjusted through the length of the rotating rod tip in the nut, and the proper rod tip can be replaced when the rod tip is damaged or the distance from the rod tip to the bulb skin is improper, so that the damaged rod tip can be conveniently repaired or replaced, the puncture rod is more practical, the puncture rod can move in an oriented mode along the linear bearing, and after the puncture rod sleeve drives the puncture rod to longitudinally puncture, the return spring controls the spring seat to reset rapidly.

Fig. 1 is a schematic structural view of the skin penetrating shaft according to the present invention.
In the figure: the device comprises a supporting seat 1, a linear bearing 2, a puncture rod sleeve 3, a puncture rod 4, a nut 5, a rod tip 6, a return spring 7, a spring seat 8, a ball seat 9, a ball bearing 10, a turntable 11 and a cushion block 12.
Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be described in detail below. It will be apparent that the described embodiments are only some, but not all, embodiments of the invention. All other embodiments, based on the examples herein, which are within the scope of the invention as defined by the claims, will be within the scope of the invention as defined by the claims.
The technical scheme of the invention is described in detail below with reference to the accompanying drawings.
A bubble skin puncture rod comprises a supporting seat 1, a linear bearing 2 penetrating through the supporting seat 1 and fixed in the supporting seat 1, a puncture rod sleeve 3 fixed in the inner ring of the linear bearing 2,
the both ends of puncture pole cover 3 stretch out outside linear bearing 2 respectively, are located the puncture pole cover 3 internal fixation of supporting seat 1 top and have puncture pole 4, puncture pole 4 top screw thread fit has nut 5, nut 5 top screw thread fit has pole point 6, pole point 6 include with nut 5 screw thread fit's cylinder and with cylinder integrated into one piece's centrum, the loop has reset spring 7 on the puncture pole cover 3 that is located supporting seat 1 below, be located the puncture pole cover 3 tip of reset spring 7 below be equipped with reset spring 7 stop matched spring seat 8.
When the puncture rod is specifically used, a bulb which is required to crush the bulb skin is fixed above the rod tip 6, the spring seat 8 is jacked, the return spring 7 is compressed, the puncture rod sleeve 3 moves linearly along the linear bearing 2, the puncture rod 4 and the rod tip 6 are driven to move upwards until the rod tip 6 crushes the bulb skin of the bulb, the return spring 7 controls the spring seat 8 to return to the initial position, and the puncture rod 4 and the rod tip 6 return to the original position.
For more effective distance between the control rod tip 6 and the filament of the bulb, avoid damaging the filament in the process of breaking the bulb skin, the lower part of the spring seat 8 is provided with a ball seat 9, a ball 10 is arranged in the ball seat 9 in a rolling way, the ball 10 extends out of the ball seat 9 and is in rolling fit with a rotary table 11 rotatably arranged below the supporting seat 1, and a cushion block 12 in rolling support fit with the ball 10 is arranged on the rotary table 11 positioned on the rolling path of the ball 10. In the rotating process of the turntable 11, the balls 10 are in rolling fit with the turntable 11, and the puncture rod sleeve 3 does not longitudinally displace; when the turntable 11 rotates to the cushion block 12 to jack up the ball 10, and when the rolling 10 rises to the highest point of the cushion block 12, the ball seat 9 also rises to the highest point at the moment, the spring seat 8 rises and further drives the rod tip 6 to break the bulb shell of the bulb, and then the ball 10 gradually descends to the turntable 11 from the cushion block 12. When the bulb envelope of the bulb is broken, the burning state and burning time of the filament in the bulb and whether the flammable gas (or explosive gas) in the surrounding environment is ignited can be observed, so that the use safety of the bulb in the flammable gas environment is obtained. In the present invention, in order to investigate whether the glowing filament is capable of igniting the combustible gas in the surrounding environment, it is preferable to place the present invention in a closed environment of the combustible gas. The ratio of the combustible gas can be adjusted according to the actual use environment of the bulb. In the present invention, the combustible gas may be a mixture of methane and air. In the invention, the height of the cushion block 12 on the turntable 11 is larger than the distance between the initial pole tip 6 and the bulb skin of the bulb and smaller than the distance between the initial pole tip 6 and the filament of the bulb, so that the displacement of the pole tip 6 can be strictly controlled, and the influence of breaking the filament on the test is avoided. Preferably, the balls 10 are rotatable only in the ball seats 9 and are not displaced in the transverse or longitudinal direction.
In particular, in order to facilitate the rolling of the balls 10 onto the pads 12, the upper surface of the pads 12 along the rolling path of the balls 10 is in a cambered surface structure.
The invention further provides a concrete embodiment of the cushion block 12, wherein the cushion block 12 along the rolling path of the ball 10 is of an isosceles triangle column structure, and the vertex angle of the isosceles triangle column is of a round angle structure.
