Abstract
The invention relates to a blasting equipment product, in particular to a detonation network connection block with an elastic card locking mechanism, which is characterized in that: one end of a body piece is a wire clamping end, and the other end of the body piece is a locking end; the wire clamping end is used for fixing a detonating tube; the locking end is used for locking a detonator to prevent the detonator from falling off the body piece; the locking end and the wire clamping end are communicated through an internal channel; the shape and the size of the internal channel are matched with those of a detonator body, and the internal channel is used for accommodating the detonator body; and when the detonator body enters the channel, an elastic card on a fixing cap of the locking end is popped under the action of applied force of the detonator, the popped elastic card can make the detonator body enter the channel, and the detonator body can be automatically returned by the popped elastic card after entering the channel. In the detonation network connection block with the elastic card locking mechanism, the locking end locks reliably and is difficult to loosen, and the fixing cap and the body are integrated when the detonation network connection block is produced.
Description
Technical field
The present invention relates to a kind of explosive product, particularly a kind of detonating network connecting block with the shell fragment retaining mechanism.
Background technology
In the explosive product, the contiguous block spare that is used for the signal transmission of plastic detonating tube and detonator lead-in wire, present known technology such as its application number of Chinese patent: 200710018370.8 is disclosed, keyed end has wherein adopted the fastening mode of one-way spiral, kayser has been carried out in end to detonating capsule, this locking device is loosening owing to the mode that adopts screw-tightened can produce the spiral screw thread unavoidably in practical operation, and what cause can't reach locking effect.
So far, the inventor discloses a kind of again at Chinese patent, a kind of detonating network connecting block clamping mechanism, wherein, by being positioned at double-deck tight latch import department in the inboard a pair of overhead kick of keyed end, inboard barb is an elastic construction, and the realization keyed end is tightly locked the detonating capsule ground floor; One fixed cap is socketed in outside the double-deck tight latch, the last lower convex platform that symmetry is arranged in the fixed cap, boss is locked with the fit engagement of outer lug boss up and down of double-deck tight latch symmetry, and fixed cap connects as one keyed end and detonating capsule, realizes the detonating capsule second layer is tightly locked.Though said structure locks reliably in the use, it is loosening to be difficult for producing, but still has some problems, technological process is loaded down with trivial details in process of production, after need inserting earlier in the passage of contiguous block detonator, refill and join locking cap, production efficiency is low, has a strong impact on manufacturing schedule.
Summary of the invention
In order to overcome the problem in the former technology, the invention provides reliable, the difficult generation of a kind of keyed end locking becomes flexible, when producing detonating network connecting block, locking cap and body are combined as a whole, when the detonating capsule admission passage, shell fragment on the keyed end locking cap flicks under the effect of detonating capsule and allows the smooth admission passage of detonating capsule, and shell fragment pins the detonating network connecting block that detonator makes detonator fixing band shell fragment retaining mechanism in passage behind the detonator admission passage.
The technical solution adopted for the present invention to solve the technical problems is: the detonating network connecting block of band shell fragment retaining mechanism is characterized in that: body member one end is the card line end, and the other end is a keyed end, and the card line end is used for fixing detonator; Keyed end is used for locking detonating capsule and prevents detonating capsule coming off from body member; Keyed end passes through internal channel UNICOM with the card line end, and the shape and size of internal channel match with the shape and size of detonating capsule body and are used to hold the detonating capsule body; When detonating capsule body admission passage, elastic card in the keyed end locking cap is flicked under the active force of detonating capsule, the elastic card that has been flicked can make detonating capsule body admission passage, flicked the elastic card self-return behind the detonating capsule body admission passage, detonating capsule body port turn-up portion is divided the inboard that just in time is stuck in the keyed end elastic card, signal transmssion line on the detonating capsule stretches out by the inner chamber of the elastic card on the locking cap, has realized that it pins detonating capsule is fixed the detonating capsule body in the passage of body member function; One or more detonator at least in the card line end draw-in groove is the time break transmission relation with a detonating capsule of vertically going up in the passage that stretches.
Described keyed end comprises locking cap and main body link, and the outer shroud projection on the main body link is complementary with the outer annular recess size in the locking cap link, and the outer shroud projection snaps in the outer annular recess, and the main body link of locking cap and main part is fixed together; On the main body link positioning convex is arranged, the detent in positioning convex and the locking cap link cooperates to be fixed; Locking cap one end is for inserting the entrance point of detonating capsule, and another port of export is the locking cap link, and the locking cap link has ring in, and outer annular recess is arranged on the interior ring; The main body link has an outer shroud, and the outer shroud projection is arranged on the outer shroud, and the interior ring size of the outer shroud of main body link and locking cap link is complementary.
Described fixed cap is circular hollow cavity, is extended with elastic card in the hollow cavity, and elastic card is between the 2-6 sheet, and elastic card is evenly distributed in the hollow cavity.
The invention has the beneficial effects as follows: when producing detonating network connecting block, locking cap and main body are combined as a whole, when the detonating capsule admission passage, shell fragment on the keyed end locking cap flicks under the effect of detonating capsule and allows the smooth admission passage of detonating capsule, and shell fragment pins detonating capsule and makes detonating capsule fixing in passage behind the detonating capsule admission passage., when assembling, just detonating capsule directly being inserted in the contiguous block passage, the shell fragment in the locking cap pins detonating capsule, and production efficiency improves, and technological process is simplified.
