Description
Technical field
The present invention relates to a kind of detonator of frame for movement, be specifically related to a kind of safety mechanical detonator.
Background technology
Detonator is the main initiating device of blasting engineering, and its effect produces to detonate and can ignite various explosive and primacord, is generally provided with medicine head, delay powder, priming and high explosive in detonator, and high explosive is the final detonator of detonator.Usual medicine head, delay powder, priming and high explosive are placed in each section in a detonator, and after lighting medicine head, need to arrive high explosive certain time delay, the time of energy burst is concentrated not, must weaken blasting effect.And medicine head, delay powder, priming and high explosive are all put together and easily produced potential safety hazard, therefore need to be isolated, change its distribution form simultaneously, and strengthen ball can strengthen by adding certain.
Summary of the invention
Technical problem to be solved by this invention is to overcome existing technological deficiency, provides a kind of safety mechanical detonator.
Technical problem to be solved by this invention adopts following technical scheme to realize:
A kind of safety mechanical detonator, comprises shell, is fixed with riffled tube above described shell, be provided with flame-arrester vent plug in described riffled tube; Described shell upper symmetry connects two swingles, is connected with extension spring between two described swingles; Two described swingles are connected with electric-controlled switch and power supply by wire, and described electric-controlled switch and power supply are connected on conducting strip by wire, and described conducting strip is fixed on enclosure; A pipe, No. two pipes, No. three pipes and No. four pipes are fixed with below described conducting strip, a described pipe is built with white phosphorus, between No. two described pipes and No. three pipes, delay powder is housed, between No. three described pipes and No. four pipes, priming is housed, between No. four described pipes and shell, high explosive is housed, in described high explosive, is placed with multiple enhancing ball.
Wherein, the mode that described riffled tube and flame-arrester vent plug are threaded connection is connected.
Wherein, described swingle and the connected mode of shell are chain connection.
Wherein, the material of described shell, flame-arrester vent plug, a pipe, No. two pipes, No. three pipes and No. four pipes is insulating materials (as safety glass); Described swingle and described conducting strip are metal material.

Beneficial effect of the present invention is: the present invention has rational in infrastructure, the advantage such as security is high, easy to use and brisance is strong, can reach desirable blasting effect.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is front view of the present invention;
Fig. 2 is the A-A sectional view of Fig. 1;
Fig. 3 is the I partial enlarged drawing of Fig. 1.
Detailed description of the invention
The technological means realized to make the present invention, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the present invention further.
As shown in Figure 1, Figure 2 and Figure 3, a kind of safety mechanical detonator, comprises shell 1, is fixed with riffled tube 2 above described shell 1, is provided with flame-arrester vent plug 3 in described riffled tube 2; Described shell 1 top symmetry connects two swingles 4, is connected with extension spring 5 between two described swingles 4; Two described swingles 4 are connected with electric-controlled switch 7 and power supply 8 by wire 6, and described electric-controlled switch 7 and power supply 8 are connected on conducting strip 9 by wire 6, and it is inner that described conducting strip 9 is fixed on shell 1; A pipe 10, No. two pipes 11, No. three pipes 12 and No. four pipes 13 are fixed with below described conducting strip 9, a described pipe 10 is built with white phosphorus 14, between described No. two pipes 11 and No. three pipes 12, delay powder 15 is housed, between described No. three pipes 12 and No. four pipes 13, priming 16 is housed, between No. four described pipes 13 and shell 1, high explosive 17 is housed, in described high explosive 17, is placed with multiple enhancing ball 18.
In the present embodiment, the mode that described riffled tube 2 and flame-arrester vent plug 3 are threaded connection is connected.
In the present embodiment, described swingle 4 is chain connection with the connected mode of shell 1.
In the present embodiment, the material of described shell 1, flame-arrester vent plug 3, pipe 10, No. two pipes, 11, No. three pipes 12 and No. four pipes 13 is insulating materials (as safety glass); Described swingle 4 and described conducting strip 9 are metal material.
In the present embodiment, described enhancing ball 18 is integrated in the ratio bonding of 1:2 by potassium permanganate and magnesium powder.
Before using, flame-arrester vent plug is only needed to screw out, two swingles contact under the effect of extension spring, two swingles, wire, conducting strip, electric-controlled switch and power supplys are by composition loop, now by Remote, electric-controlled switch is opened, whole loop is by generation current, due to the effect of electric current, conducting strip temperature raises, and the rising of conducting strip temperature will cause white phosphorus spontaneous combustion and explode, finally gradually high explosive is passed in blast, when high explosive explosion time, owing to strengthening the existence of ball, by the huge ignition heat of generation and impulsive force.
More than show and describe general principle of the present invention, principal character and advantage of the present invention.The technical staff of the industry should understand; the present invention is not restricted to the described embodiments; what describe in above-described embodiment and description just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.Application claims protection domain is defined by appending claims and equivalent thereof.
