Description
Technical Field
The utility model relates to a civilian explosive technical field, concretely relates to novel initiating explosive device lid.
Background
The detonator is used for detonating ammonium nitrate fuel oil, emulsion explosive and other low sensitivity explosives, and is an ideal blasting source for mine blasting, engineering blasting and large-scale open pit coal mines. The common initiation modes of the existing initiator include detonator initiation and detonating cord initiation. The detonator structure comprises a shell, a base and a cover which can be mutually buckled, the detonator base and the shell are buckled firstly when explosive is filled, then the base and the shell are directly inserted into the bottom of a mould needle, then the high-energy explosive core is filled in for pouring, and the cover is buckled after the pouring is finished. However, the existing detonator cover has a simple structure, namely a common flat cover (as shown in fig. 1), a through hole is arranged on the flat cover for a detonator pipeline or a detonating cord to penetrate out, the stability is poor after the flat cover is buckled with a shell, the flat cover is easy to fall off, and the flat cover does not have the function of fixing the detonator and the detonating cord.
Disclosure of Invention
In view of this, the utility model discloses to the problem that prior art exists, provide a novel initiating explosive device lid.
The technical scheme of the utility model is that:
a novel detonator cover comprises a cover body, wherein a through hole for fixing a detonating cord or a detonator pipeline is arranged on the cover body; the cover body is provided with a plurality of fixing claws on the inner side.
Preferably, the number of the through holes is 2, and the hole diameters of the two through holes are different.
Preferably, the number of the fixing claws is 4.
Furthermore, each fixing claw is composed of a rod-shaped claw body and a claw head arranged at one end of the rod-shaped claw body, the other end of the rod-shaped claw body is fixed at the bottom of the cover body, the claw head is of an ellipsoidal block structure and has the function of enlarging the contact area between the claw head and the pouring liquid, and after the pouring liquid is solidified, the ellipsoidal block structure is beneficial to being tightly clamped in the fixing claw to prevent the fixing claw from falling off, so that the fixing strength of the whole fixing claw is enhanced.
The technical effects of the utility model are that: the utility model discloses cover the increase at initiating explosive device and be used for fixed detonating cord or the through-hole of detonator pipeline to and increase the stationary dog that is used for strengthening the lid steadiness, can further promote loading steadiness and the security of detonating cord or detonator in initiating explosive device shell, and strengthen the steadiness of initiating explosive device lid, and then promote whole initiating explosive device's detonating reliability and accuracy.

Detailed Description
The present invention will now be described in further detail with reference to the accompanying drawings and specific examples, which are given by way of illustration and not of limitation.
As shown in fig. 2-5, the utility model provides a novel initiating explosive device lid, including lid 1, be equipped with 2 through-holes 2 that are used for fixed detonating cord or detonator pipeline on the lid 1, and two the through-hole aperture is inequality, wherein the through-hole diameter and the detonator pipe diameter phase-match of large aperture. The different design of the apertures of the two through holes 2 has the following functions: on one hand, when the detonator is used for detonating, the detonator penetrates through the large-aperture through hole of the cover body 1, penetrates through the detonator through hole of the detonator base after passing through the inside of the shell, is inserted into the other detonator through hole of the detonator base (the existing detonator base is provided with two detonator through holes with the same size), and is fixed in the shell. On the other hand, when the detonating cord is adopted for detonating, the detonating cord penetrates through the large-aperture through hole of the cover body 1, penetrates through the detonator through hole of the detonator base after passing through the interior of the shell, is inserted into the other detonator through hole of the detonator base, penetrates through the small-aperture through hole of the cover body 1 after passing through the interior of the shell again, and then penetrates through the other detonator in the same way, namely, the detonating way allows a plurality of detonators to be connected in series. In addition, although the existing detonator cover also allows a plurality of detonators to be connected in series in a detonating mode of the detonating cord, the detonating cord finally penetrates through the same through hole of the cover body, so that the detonating cord is very easy to be coiled and wound together, and the detonating effect is further influenced.
The inner side of the cover body 1 is provided with 4 fixing claws 3. Each fixing claw 3 consists of a rod-shaped claw body 4 and a claw head 5 arranged at one end of the rod-shaped claw body 4, the other end of the rod-shaped claw body 4 is fixed at the bottom of the cover body 1, the claw head 5 is of an ellipsoidal block structure, the ellipsoidal block structure is designed to increase the contact area between the ellipsoidal block structure and the pouring liquid, and after the pouring liquid is solidified, the ellipsoidal block structure is favorable for being tightly clamped in the ellipsoidal block structure to prevent the falling off, so that the fixing strength of the whole fixing claw 3 is enhanced.
The utility model discloses a use does: after the base of the detonator is butted with the shell of the detonator, the base and the shell are directly inserted into the bottom of a mold pin, then the high-energy explosive core is filled in for pouring, and the cap of the detonator is buckled after the pouring is finished, so that a complete detonator is formed. When the detonator is used, a detonator (or a detonating cord) penetrates through the large-aperture through hole of the detonator cover and then penetrates out of the detonator through hole of the detonator base, and then penetrates into the shell from the other detonator through hole of the detonator base, and if the detonator is used for detonating, the detonator directly stays in the shell; if the detonating fuse is adopted for detonating, the detonating fuse continuously penetrates out of the small-aperture through hole of the detonating fuse cover, and other detonating fuses can be continuously connected, so that the contact area of the detonating fuse and the detonating fuse is increased, and the detonating reliability is further enhanced.
To sum up, the utility model discloses cover the increase at the initiating explosive device and be used for fixed detonating cord or the through-hole of detonator pipeline to and increase the stationary dog that is used for strengthening the lid steadiness, can further promote detonating cord or the loading steadiness and the security of detonator in the initiating explosive device shell, and strengthen the steadiness of initiating explosive device lid, and then promote whole initiating explosive device's detonating reliability and accuracy.
