Abstract
The utility model discloses a novel non-initiator primer casing, which comprises a pipe wall (1) and a pipe bottom (2), wherein the middle-upper portion of the inner cavity of the pipe wall (1) is provided with a downward taper, and the middle-lower portion of the inner cavity of the pipe wall is provided with a projecting table (3) which is a rotary body with the same inner diameter, further the height of the projecting table (3) is one third of the total height of the pipe wall (1). The projecting table with the shape of the rotary body is arranged at the middle-lower portion of the inner cavity of the pipe wall, thereby the utility model has a large supporting surface of a reinforced cap, and the force is even, further the positioning is accurate and stable. The utility model is capable of being finished once on the production-lines, thereby the production is convenient.
Description
Affiliated technical field
The utility model belongs to a kind of detonator part, is a kind of shell of nonpriming material detonator particularly.
Background technology
In the prior art, the shell of detonator is cylindric, and its inner chamber has certain tapering, promptly the upper end open of shell to the bottom internal diameter from large to small, seamlessly transit.Explosive is equipped with in the inner chamber bottom of shell, and the explosive top is a strengthening cap, and strengthening cap has downward pressure that explosive is tightened up.The primer casing of this structure has following deficiency: strengthening cap compresses explosive under external force, and the quantity of explosive is relatively-stationary, but can cause outer casing rupture when the downforce of strengthening cap is excessive, can cause its poor effect when too small.Especially adopting the primer casing of non-priming, be not provided with centre bore on the strengthening cap, is by impulsive force strengthening cap to be broken to realize igniting the bottom explosive fully, thereby very important to the location of strengthening cap.At present, primer casing has the version at middle part " card waist ", at primer casing inwardly retraction of middle part is arranged that is:, forms a raised points at inwall.Its weak point is: the strong point is too small, holding capacity a little less than, effect is bad.
Summary of the invention
The purpose of the utility model is to overcome the above-mentioned deficiency of prior art, and a kind of improved primer casing is provided, and it is firm to the strengthening cap accurate positioning, cracky not, and result of use is good.
For reaching above-mentioned purpose, the utility model is taked following technical scheme: the utility model includes: the tube wall and the pipe end, it is characterized in that: the middle and upper part of tube wall inner chamber has downward tapering, and the middle and lower part of tube wall inner chamber is provided with protruding platform, and protruding platform is the rotary body of internal diameter unanimity.
The utility model is taked technique scheme, has following beneficial effect: the utility model after placing explosive, presses down strengthening cap owing to be provided with the protruding platform of rotary body shape in the middle and lower part of tube wall inner chamber, and strengthening cap is locked on the protruding platform, can not move down.The projection platform is big to the supporting surface of strengthening cap, and is stressed even, firm to the strengthening cap accurate positioning.The utility model can once be finished on streamline, is convenient to produce.
Description of drawings
Below in conjunction with drawings and Examples the utility model is elaborated:
Fig. 1 is the utility model master TV structure sketch.
Fig. 2 is the utility model plan structure sketch.
Mark among the figure: 1-tube wall, the 2-pipe end, 3-projection platform
The specific embodiment
By Fig. 1, shown in Figure 2, the utility model includes: the tube wall 1 and the pipe end 2,, the middle and upper part of tube wall 1 inner chamber has downward tapering, and the middle and lower part of tube wall 1 inner chamber is provided with protruding platform 3, and protruding platform 3 is the rotary body of internal diameter unanimity.Projection platform 3 is 1/3rd of tube wall 1 total height.
Claims (2)
1. novel nonpriming material detonator shell, it includes: the tube wall (1) and the pipe end (2), it is characterized in that: the middle and upper part of tube wall (1) inner chamber has downward tapering, and the middle and lower part of tube wall (1) inner chamber is provided with protruding platform (3), and protruding platform (3) is the rotary body of internal diameter unanimity.
2. a kind of novel nonpriming material detonator shell according to claim 1 is characterized in that: protruding platform (3) is 1/3rd of tube wall (1) total height.
