Embodiment 1

[0045] pass Figure 1-Figure 5 Further illustrate the structure and working principle of the detonator locking device of the present invention, by Figure 1-Figure 3 It can be seen that the detonator lock device of the present invention includes a base 1 , a lock body 2 fixed on the base 1 , and a lock sleeve 3 .

[0046] Figure 4 Shown is figure 1 Schematic diagram of the lock body in . Depend on Figure 4It can be seen that the locking body 2 includes a bottom connecting tube 21 and a locking tube 22 extending on the bottom connecting tube 21 , and the locking body 2 is fixed on the base 1 through the bottom connecting tube 21 . The outer surface of the locking tube 22 is an outer tapered surface with a large upper part and a smaller lower part, and the locking tube 22 is evenly divided into a plurality of radially extending bayonets 23 along its circumferential direction.

Embodiment 2

[0052] The difference between this embodiment and embodiment 1 is: as Figure 6 and Figure 7 As shown, the detonator lock device also includes an adjustment rod 4, and one end of the adjustment rod 4 is from Figure 4 The shown bottom connecting pipe 21 extends into the lock tube 22, and is used to adjust the axial position of the fire detonator to be clamped in the lock tube 22, so as to be suitable for processing different numbers of fire detonators.

[0053] Further preferably, the base 1 is provided with an axial cavity, and the bottom connecting pipe 21 of the locking body 2 is inserted into the axial cavity of the base 1, and the bottom end of the axial cavity is provided with an inner socket for blocking the bottom connecting pipe 21. The overturn edge 10 and the bottom connecting pipe 21 are detachably fixed on the base 1 through a limiting mechanism, and the limiting mechanism includes a hollow bolt 5 . Such as Figure 8 The structure of the hollow bolt 5 is shown...

Embodiment 3

[0059] The difference between this embodiment and embodiment 2 is: as Figure 10 As shown in the structural diagram of the lock body, the flap of the lock tube 22 is provided with two protrusions 23 from top to bottom. When the lock tube 22 is locked, the protrusions 23 respectively fit together to form a ring structure. In the process of locking the lock tube 22, two sealing rings are produced between the fire detonator and the fuse, which further improves the sealing between the fire detonator and the fuse.

Abstract

The invention discloses a detonator lock device for clamping a fire detonator and a fuse, which comprises a base, a lock body, a lock sleeve, and a driving mechanism. The lock body includes a bottom joint and extends on the bottom joint. The locking tube, the bottom connecting tube is fixed on the base, the outer surface of the locking tube is an outer tapered surface with a large upper part and a smaller one at the lower part, and the locking tube is evenly divided into a plurality of radially expanding flaps along its circumference; The inner wall of the sleeve is provided with an inner cone that matches the taper of the outer cone of the lock tube, and the lock sleeve moves up and down relative to the lock tube and is set on the outer periphery of the lock tube to lock or loosen the lock tube; the drive mechanism It is arranged on the base to drive the lock sleeve to move up and down. The detonator lock device of the present invention is simple in structure, and the lock tube of the lock body is contracted by the lock sleeve to clamp the fire detonator and the fuse, so that the sealing performance of the fire detonator and the fuse is better after the fire detonator is combined, and the blasting of the fire detonator is improved. Safety and reliability, improve efficiency and facilitate operation.

Description

technical field [0001] The invention relates to the field of civil explosives, in particular to a lock device used for the lock of a detonator. Background technique [0002] In the process of pyrotechnic product processing, the lock is an important processing procedure of the fire detonator. When the fire detonator is combined with the fuse, the fuse is usually put into the cavity of the fire detonator, and then clamped with the detonator pliers. Since the clamping position of the detonator pliers cannot be controlled forcibly, accidents may easily occur once the clamping position is improper. [0003] If the engineer does not use enough force during the processing, or the detonator clamp and the fire detonator are not in a vertical state, the clamping surface will form a slope when clamping the fire detonator, resulting in uneven force applied to the outer peripheral surface of the fire detonator, which will cause the fire detonator and the fuse. The clamping of the cable ...
