Abstract
The utility model discloses a combination-type delay-body element, which comprises a delay-body inner element and delay powder which are arranged inside a metal tube shell in order, wherein, a delay-body outer element is arranged between the delay-body inner element and the metal tube shell; the delay-body outer element is provided with ventilating micro holes; the delay-body outer element is a cylindrical body, and the cylindrical body is provided with three or four ventilating micro holes; the delay-body outer element is shaped like I, and the upper part and the lower part of the delay-body outer element are provided with ventilating micro holes; the ventilating micro holes are arranged on the upper edge and the lower edge of the I-shaped delay-body outer element, and the upper and the lower ventilating micro holes are staggered. The element is completely free of the air cushion that is arranged between the delay-body element and the initiating explosive, so that the delay-body element realize the best time delay effect, thereby guaranteeing the delay accuracy of a delay exploder; moreover, the floating powder on the inner wall of the metal tube shell is not brought out, thereby reducing the consumption volume of the lead metal material, and greatly reducing the production cost of the delay exploder.
Description
Technical field
The utility model belongs to the rupture element field, specially refers to a kind of combined type extension body member that is used for delay detonator.
Background technology
In blasting technique, detonator is an indispensable medium, the kind of detonator is a lot, delay detonator is a kind of detonator general and the most commonly used, its basic structure is, metal-back body, the payment to a porter of igniting, plastic plug, inner air tube chamber, the assembly of igniting, extension body member and the delay powder that comprises are included in interior priming of tube shell and high explosive etc. then; The quality of weighing a detonator quality is many-sided, and the body member of wherein delaying and the delay powder part that comprises are the most important mass parameters of delay detonator.At present, the extension body member that each detonator manufacturer uses is that lead pipe is packed into behind the delay powder, through drawing, cut into the cylinder that is consistent with detonator Can internal diameter, and this extension body member high explosive of in the detonator metal-back, packing into successively, behind the priming, filling extension body member.Because extension body member and shell internal diameter are basic identical, make like this between extension body member and the priming to have compressed air in the filling process, are called air cushion on the specialty.Because this structure of extension body member in the delay detonator, in production engineering, be easy to produce air cushion, had a strong impact on the accuracy of delay detonator burst time like this, coarse burst time, influenced the effect of whole blasting engineering, the body member of therefore delaying should be improved its structure as the most important part of delay detonator quality standard.
Summary of the invention
The utility model is in order to solve the deficiencies in the prior art, a kind of air cushion that can eliminate fully between extension body member and the priming is provided, make the extension body member reach best defer time effect, guarantee the higher combined type extension body member of delay detonator time-delay accuracy.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of combined type extension body member, comprise element and delay powder in the extension body that is successively set in the Can, be provided with the external element of delaying in the described extension body between element and the Can, the external element of described extension is provided with ventilating microhole.
The external element of described extension is a cylinder, and described cylinder is provided with 3 or 4 ventilating microholes.
The external element of described extension is " worker " font, and the external element of described extension is provided with ventilating microhole in the position up and down.
Described ventilating microhole is arranged on the delay upper and lower edge of external element of " worker " font, and upper and lower ventilating microhole is staggered.
The material of the external element of described extension is aluminium, iron or plastics.
Compared with prior art, the utility model is owing to be provided with ventilating microhole, eliminate the air cushion between extension body member and the priming fully, make the extension body member reach best defer time effect, guarantee the accuracy of delay detonator time-delay, on, the setting of staggering of following passage, the floating medicine that has guaranteed the Can inwall is not taken out of, use aluminium, materials such as iron have replaced part lead metal material, adopt the structure of " worker " font, present existing extension body member diameter has been reduced more than 1/2nd, thereby reduced the consumption of lead metal material, reduced the production cost of delay detonator significantly.

Fig. 1 is the structural representation of a kind of embodiment of the present utility model;
Fig. 2 is the A-A cutaway view of Fig. 1;
Fig. 3 is the structural representation of another kind of embodiment of the present utility model;
Fig. 4 installs the structural representation of priming for Fig. 1 bottom.
Among the figure: 1 delay powder, the external element of 2 extensions, element in the 3 extension bodies, 4 ventilating microholes, 5 Cans, 6 primings.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Referring to Fig. 1, Fig. 2 and Fig. 3, a kind of combined type extension body member is provided with element 3 and delay powder 1 in delay external element 2, the extension body successively in Can 5, and element 3 is provided with ventilating microhole 4 in the extension body.
As shown in Figure 1, the external element 2 of delaying is " worker " font, and the delay upper and lower edge of external element 2 of " worker " font is provided with ventilating microhole 4, and upper and lower ventilating microhole 4 is staggered, and ventilating microhole 4 can be provided with 6 to 8 as required.
As shown in Figure 3, the external element 3 of delaying is cylinder, and cylinder is provided with 3 or 4 ventilating microholes.
As shown in Figure 4, the below of combined type extension body member is a priming 6, is easy to generate air cushion between combined type extension body member and priming 6, adopts structure of the present utility model, can eliminate the air cushion that is produced fully.
The utility model is reasonable in design, compact conformation, saving cost, adopt combined type extension body member of the present utility model, can eliminate the air cushion between extension body member and the priming, make the extension body member reach best delayed effect, guarantee the accuracy of delay detonator time-delay.
Above-described embodiment, the utility model specific embodiment a kind of more preferably just, the common variation that those skilled in the art carries out in the technical solutions of the utility model scope and replacing all should be included in the protection domain of the present utility model.
