Abstract
The utility model relates to a detonator sealing device. The device comprises a cylindrical body, a clamping nut, a bottom plate, a sealing core, an adjusting screw rod and a positioning nut, wherein the cylindrical body is provided with a screw thread; the clamping nut is sleeved on the body; the bottom plate is positioned below the body and used for bearing the body; the sealing core is inserted into the body and the clamping nut; the adjusting screw rod is inserted into the sealing core; the positioning nut is positioned below the bottom plate and sleeved on the adjusting screw rod; a handle horizontally extends out of the side face of the clamping nut; the upper part of the clamping nut is provided with a bearing seat which is matched with the sealing core; a screw thread on the clamping nut is matched with the screw thread on the body; bumps extend from the upper end of the sealing core to the two sides and are clamped on the upper surface of the bearing seat; and the lower part of the sealing core is tightened inwards under the restraining action of the body. The bumps on the upper part of the sealing core are only clamped on the upper surface of the bearing seat but not tightened, so that the sealing core has one-way sealing effect and can be prevented from being broken relative to the prior art.
Description
Technical field
The utility model relates to a kind of closing in device, especially in order to the primacord closing in device of closing in primacord.
Background technology
The general closing in core that adopts closes up primacord in the existing primacord closing in device.In the existing primacord, the general employing up and down of closing in core closed up simultaneously, makes the closing in core very easily rupture, and causes primacord closing in device to use.
So, need a kind of new primacord closing in device to address the above problem.
The utility model content
The purpose of this utility model is the deficiency that exists at prior art, and a kind of primacord closing in device of unidirectional closing in is provided.
For achieving the above object, the utility model primacord closing in device can adopt following technical scheme:
A kind of primacord closing in device, it comprises: cylindrical and have a body of screw thread, be sheathed on the grip 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 grip 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 grip nut has extend horizontally away handle, the top of grip nut is provided with the bearing support that cooperates with described closing in core, the threads engaged that screw thread on the described grip 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 support.
Compare with background technology, the utility model primacord closing in device is 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 support, 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 support, 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 the utility model primacord closing in device.
Fig. 2 is the sectional exploded view of the utility model primacord closing in device.
Embodiment
Below in conjunction with the drawings and specific embodiments, further illustrate the utility model, should understand these embodiment only be used to the utility model is described and be not used in the restriction scope of the present utility model, after having read the utility model, 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 utility model.
See also Figure 1 and Figure 2, the utility model discloses a kind of primacord closing in device 100 that is mainly used in mine blasting, and it comprises: cylindrical and have screw thread body 20, be sheathed on grip nut 30 on the body 20, be positioned at below the body 20, insert the closing in core 50 of body 20 and grip 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 grip nut 30 extend horizontally away handle 31, grip nut 30 is provided with the bearing support 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 support 32.The threads engaged that screw thread on the described grip nut 30 and body 20 are provided with, when rotating grip 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 support 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 primacord (not shown) (closing up in a bottom).Screw thread in the present embodiment on grip 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 primacord flexibly and tighten up height dimension.
