The present invention adopts physical construction to carry out the design of tripping device, mainly comprise separation mechanism and the mechanism that performs an action, utilize the mechanical parts such as wedge face, steel ball, thrust spring that bigger axial force is converted into less power of pulling pin, avoid adopting priming system blast mode, can effectively minimizing action time noise, reduce potential safety hazard.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention in main apparent direction.
Embodiment
Below in conjunction with accompanying drawing, the present invention is described in detail:
A kind of low noise disengagement bolts, comprise screw rod 1 and sleeve 12, sleeve 12 is provided with electro-magnet 13, electro-magnet 13 front end is provided with electro-magnet column cap 14, right-hand member at screw rod 1 is fixedly installed screw rod boss 2, the outer groove 3 of annular it is provided with in the front end of screw rod boss 2, left end at sleeve 12 is provided with sleeve boss 4, central authorities at sleeve boss 4 are provided with centre hole 5, centre hole 5 is provided with groove 6 in annular, the outer side wall of sleeve boss 4 is provided with outside screw 7, the right-hand member inner side-wall of joint sleeve 9 is provided with internal thread 8, joint sleeve 9 is provided with piston-like barrel cover 10, right-hand member in piston-like barrel cover 10 is plugged in centre hole 5, right-hand member in piston-like barrel cover 10 is provided with spacing hole 11, electro-magnet column cap 14 activity is plugged in the right-hand member hole of piston-like barrel cover 10, spacing steel ball 15 it is provided with between the side of electro-magnet column cap 14 and spacing hole 11, it is provided with thrust spring 16 in the right-hand member hole of piston-like barrel cover 10, the right-hand member top of thrust spring 16 is connected in the right-hand member of piston-like barrel cover 10 on side, the left end of thrust spring 16 and the top, right side of screw rod boss 2 are connected together, in the left end of piston-like barrel cover 10, hole is wedge shape left large and right small, it is provided with between the groove 3 outer with annular of side in the left end of piston-like barrel cover 10 and it is separated steel ball 17.
In the left end of screw rod boss 2 and joint sleeve 9, it is provided with packing ring 19 between side, screw rod 1 is provided with separation nut 18.
Installation process of the present invention is as follows: packing ring 19 is placed in joint sleeve 9, then is connected with screw rod 1, installs separation steel ball 17; Thrust spring 16 is placed in piston-like barrel cover 10, is arranged on outside separation steel ball 17, compresses thrust spring 16; By sleeve 12 and the joint sleeve 9 of being screwed, spacing steel ball 15 is installed; Electro-magnet column cap 14 is installed to inside spacing steel ball 15; By screw, electro-magnet right side cover plate 20 is installed again. Under thrust spring 16 acts on, whole tripping device is in locking state. When whole disengagement bolts is installed on actual product, by the end face of separation nut 18 and screw rod 1 and separated part, it is provided that connect preliminary tension, it is achieved whole installation. Wherein, being provided with two spacing steel balls 15 at spacing hole 11 place, spacing steel ball 15 is carried out spacing by electro-magnet column cap 14 so that piston-like barrel cover 10 and joint sleeve 9 axially can not relative movements; In annular, outer groove 3 place is provided with 10 separation steel balls 17, by joint sleeve 9, the outer groove 3 of annular, steel ball seat 19, it is spacing so that screw rod 1 can not be separated.
The working process of the present invention is as follows: when low noise disengagement bolts is separated, by giving electro-magnet 13 power on signal, electro-magnet 13 action, electro-magnet column cap 14 produces displacement to the right, piston-like barrel cover 10 is under the reactive force of thrust spring 16, spacing steel ball 15 is squeezed in centre hole 5, piston-like barrel cover 10 is to moving right, under the effect of preliminary tension and thrust spring power, release separation steel ball 17 and screw rod 1 spacing, screw rod 1, separation nut 18 are as one, and the part formed with the remaining parts of this device departs from mutually, and low noise disengagement bolts completes separating action.
The invention has the beneficial effects as follows: this low noise disengagement bolts utilizes electro-magnet as actuating mechanism, adopt wedge face, steel ball, thrust spring etc. as separation mechanism, larger axis when separation being connected carries out staged conversion to power to be reduced, it is achieved the less electro-magnet power of pulling pin frees disengagement bolts. Adopting electro-magnet as action element during separation, action noise is little; There is not priming system, potential safety hazard when installation, storage is less; Adopting the design of separation steel ball, under reducing big preliminary tension, steel ball is to the impression of contact surface, avoids contact surface distortion to cause the stuck of steel ball; Adopt the design of different wedge face angles, it is possible to change the pressure of electro-magnet column cap, be conducive to reducing electro-magnet and pull pin power.
