Abstract
The invention relates to a shell nosing device for detonating tubes, which comprises a cylindrical main body with a thread, a clamping nut sheathed on the main body, a bottom board located below the main body and used for loading the main body, a shell nosing core inserted in the main body and the clamping nut, an adjustment screw inserted in the shell nosing core ,and a locating nut located below the bottom board and sheathed on the adjustment screw, wherein a handle laterally is stretched from the side face of the clamping nut, the upper part of the clamping nut is provided with a bearing block matched with the shell nosing core, and the thread on the clamping nut is matched with the thread arranged on the main body; a convex part stretches from both sides of the upper end of the shell nosing core, and the convex part is clamped on the upper surface of the bearing block; the lower part of the shell nosing core is tightened inward under the constraint of the main body; and moreover, because the convex part on the upper part of the shell nosing seaming core is only clamped on the upper surface of the bearing block and can not be tightened, and thus, the shell nosing core has the effect of one-way shell nosing. Compared with the prior art, the invention can prevent the shell nosing core from breaking.
Description
Technical field
The present invention relates to a kind of closing in device, especially in order to the detonator closing in device of closing in detonator.
Background technology
The general closing in core that adopts closes up detonator in the existing detonator closing in device.In the existing detonator, the general employing up and down of closing in core closed up simultaneously, makes the closing in core very easily rupture, and causes detonator closing in device to use.
So, need a kind of new detonator closing in device to address the above problem.
Summary of the invention
The present invention seeks to deficiency, a kind of detonator closing in device of unidirectional closing in is provided at the prior art existence.
For achieving the above object, detonator closing in device of the present invention can adopt following scheme:
A kind of detonator closing in device, it comprises: cylindrical and have a body of screw thread, be sheathed on the binding nut on the body, be positioned at below the body base plate in order to the carrying body, insert the closing in core in body and the binding nut, insert the adjustment screw rod of described closing in in-core and be positioned under the base plate and be sheathed on the setscrew nut of adjusting on the screw rod, the side of described binding nut has extend horizontally away handle, the top of binding nut is provided with the bearing block that cooperates with described closing in core, the threads engaged that screw thread on the described binding nut and body are provided with, the upper end of described closing in core is extended with protuberance to both sides, and this protuberance is stuck in the upper surface of bearing block.
The present invention is compared with prior art: be extended with protuberance by the upper end at the closing in core to both sides, this protuberance is stuck in the upper surface of bearing block, inwardly tighten up under the constraint of body the bottom of closing in core, and because the protuberance on closing in core top only is stuck in the upper surface of bearing block, can do not tightened up, thereby the closing in core plays the effect of unidirectional closing in, with respect to background technology can prevent to close up core fracture.
Description of drawings
Fig. 1 is the constitutional diagram of analysing and observe of detonator closing in device of the present invention.
Fig. 2 is the sectional exploded view of detonator closing in device of the present invention.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, further illustrate the present invention, should understand the following specific embodiment only is used to the present invention is described and is not used in and limit the scope of the invention, after having read the present invention, those skilled in the art all fall within the application's claims institute restricted portion to the modification of the various equivalent form of values of the present invention.
See also Figure 1 and Figure 2, the present invention discloses a kind of detonator closing in device 100 that is mainly used in mine blasting, and it comprises: cylindrical and have screw thread body 20, be sheathed on binding nut 30 on the body 20, be positioned at below the body 20, insert the closing in core 50 of body 20 and binding nut 30 from top to bottom, insert the adjustment screw rod 60 of described closing in core 50 and be positioned at base plate 40 times and be sheathed on setscrew nut 70 on the adjustment screw rod 60 from bottom to top in order to the base plate 40 of carrying body 20.The top that the side of described binding nut 30 extend horizontally away handle 31, binding nut 30 is provided with the bearing block 32 that cooperates with described closing in core 50.The upper end of described closing in core 50 is extended with protuberance 51 to both sides, and this protuberance 51 is stuck in the upper surface of bearing block 32.The threads engaged that screw thread on the described binding nut 30 and body 20 are provided with, when rotating binding nut 30, turning handle 31 moves upward with respect to body, the protuberance 51 that drives closing in core 50 simultaneously moves upward closing in core 50, inwardly tighten up under the constraint of body 20 bottom of closing in core 50, and because 51 upper surfaces that are stuck in bearing block 32 of protuberance on closing in core 50 tops, can do not tightened up, thereby closing in core 50 plays the effect to the unidirectional closing in of detonator (not shown) (closing up in a bottom).Screw thread in the present embodiment on binding nut 30 and the body 20 all adopts left-handed square thread, clockwise rotate the match operation custom, and because closing in core 50 unidirectional tightening up, thoroughly solved the difficult problem of closing in core easy fracture in the background technology, adjust screw rod 60 and setscrew nut 70 cooperations, adjust detonator flexibly and tighten up height dimension.
Claims (2)
