Abstract
The invention relates to a detonating equipment product, in particular to a detonating network connecting block locking mechanism which is characterized in that one end of a body part is a clamping end, and the other end of the body part is a locking end, wherein the clamping end is used for fixing a detonating tube; the locking end is used for locking a primer detonator so as to prevent the primer detonator from falling off; a pair of reverse hooks with elastic structures at the inner side of the locking end are positioned at the inlet of a double-layer locking clamp part so as to realize first-layer locking of the primer detonator by the locking end; a fixed cover is sleeved and connected outside the double-layer locking clamp part, an upper lug boss and a lower lug boss which are symmetrical are arranged in the fixed cover, an upper outer lug boss and a lower outer lug boss of the lug bosses which are symmetrical with the double-layer locking clamp part are matched, engaged and locked, and the locking end and the primer detonator are connected into a whole by the fixed cover so as to realize second-layer locking to the primer detonator. The invention provides the detonating network connecting block locking mechanism which is reliable to lock, not easy to loosen and damage the hook mouth when the detonating tube of the clamping end is blocked and easy to take out after assembling.
Description
Technical field
The present invention relates to a kind of explosive product, particularly a kind of detonating network connecting block locking 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.Its two cards line end adopts the inlet wire formula device that has shell fragment, form self-locking after can making plastic detonating tube enter card line end holddown groove, but because minimum mouth of hook width is less than the external diameter of signal transmssion line, thereby may cause when causing plastic detonating tube to snap in the mouth of hook damaging, influence whole explosion, and signal transmssion line snaps in and is difficult to behind the holddown groove take out.
Summary of the invention
In order to overcome the problem in the former technology, the invention provides the locking of a kind of keyed end reliable, be difficult for producing loosening, it is not fragile that the detonator of card line end snaps in the mouth of hook, and be easy to the detonating network connecting block locking mechanism that takes out after packing into.
The technical solution adopted for the present invention to solve the technical problems is: a kind of detonating network connecting block locking 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 to lock detonating capsule and prevents coming off of detonating capsule; Keyed end card line end is by internal channel UNICOM, and the shape and size of internal channel match with the shape and size of detonating capsule and are used to hold detonating capsule; After detonating capsule is inserted into the card line end from the keyed end feeder connection, the detonating capsule port section just in time is stuck in the inboard a pair of overhead kick of keyed end, the inboard a pair of overhead kick of keyed end is positioned at double-deck tight latch import department, inboard a pair of overhead kick 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.
Described card line end comprise can be crooked bent beam, one end and the body member of bent beam connect as one, the bent beam other end is open port organization, port organization has the grab of an ecto-entad, the port that passage leads to the card line end has one and the corresponding coupler body of grab, the bent beam bending can make grab be stuck on the coupler body, and when grab was not connected with coupler body, the bent beam intrados formed unlimited cavity; Bent beam is connected with grab, forms closed arc-shaped cavity; After detonator enters unlimited cavity by the detonator inlet port during use, make the grab of bent beam one side and body member upper hook body locking back form closed arc-shaped cavity, closed arc-shaped cavity can be fixed one or more detonator; One or more detonator in the closed arc-shaped cavity of card line end is the time break transmission relation with a detonating capsule of vertically going up in the passage that stretches.
The port of described card line end passage has in the holddown groove, and the notch of holddown groove has coupler body.
Described grab is a kind of bidentate shape elastic component, and in the time of in detonator is clamped on the arc-shaped cavity that is formed by bent beam, elastic component and coupler body can unclamp up and down.
The invention has the beneficial effects as follows: owing to adopt double-deck locking device, inside and outside the double-deck tight latch in the double-deck locking device draw-in groove is arranged all, this just makes detonating capsule obtain double-deck tight lock, and the fastening cover difficult drop-off in the fastener outside has simultaneously guaranteed the fastness of every layer of locking device.
