Abstract
The utility model relates to a theftproof device, in particular to a theftproof device of a motor. The utility model has the technical schemes that the theftproof device mainly comprises a conical eccentric screw and a stepped screw cap, one end of the conical eccentric screw is provided with a conical cap in which a stepped eccentric circular groove is arranged, the other end of the conical eccentric screw is in threaded connection with the stepped screw cap. The utility model has the beneficial effects that the theftproof device of the motor and a special wrench are designed uniquely, the theftproof device is different from the common motor screw, thus the theftproof effect is achieved, in addition, the theftproof device has simple structure, convenient operation and good theftproof performance, and can be widely popularized and used, moreover, the cost is lower, the economic benefit is good, the labor intensity is reduced, and the crude oil output loss due to the replace of the motor is reduced.
Description
One, technical field:
The utility model relates to a kind of anti-theft device, particularly a kind of motor anti-theft device.
Two, background technique:
At present, the pumping unit major part that the oil field is used is located in the field, though existing Online Video surveillance and control measure still can exist supervision not in place even still there are some remote places not install or to install, take place that motor takes place easily and lose phenomenon, bring loss significantly to manufacturing operation.In addition, the existing pumping-unit motor that uses adopts the anti-theft measure of soldering and sealing retaining screw, when changing motor once more, must use the electrogas welding cutting, could carry out, and makes complicated operation, loaded down with trivial details, has increased because of changing the crude output loss that motor causes.
Three, summary of the invention:
The purpose of this utility model is exactly the above-mentioned defective that exists at prior art, provide a kind of simple in structure, be convenient to operation, the motor anti-theft device that theftproof performance is good.
Its technological scheme is: mainly be made up of conical eccentric screw rod and stepped shaft nut, one end of described conical eccentric screw rod is provided with tapered cap, tapered cap inside is provided with the eccentric circular groove of stepped shaft, and the other end of described conical eccentric screw rod is threaded with the stepped shaft nut.
The eccentric circular groove of above-mentioned stepped shaft comprises big circular groove and the groove composition than small circular, and big circular groove is positioned at the center of tapered cap, is located at the eccentric position of circular greatly groove than the groove of small circular.
The beneficial effects of the utility model are: motor anti-theft device and special spanner design are unique, are different from existing common electric machine screw, thereby reach antitheft purpose; In addition, simple in structure, be convenient to the operation, theftproof performance is good, can extensively promote the use of; Have input cost lower again, economic benefit is good; Reduced labor intensity, also reduced because of changing the crude output loss that motor causes.
Four, description of drawings:
Accompanying drawing 1 is a structural representation of the present utility model;
Accompanying drawing 2 is plan views of tapered cap of the present utility model.
Five, embodiment:
In conjunction with the accompanying drawings 1 and 2, the utility model mainly is made up of conical eccentric screw rod 1 and stepped shaft nut 2, one end of conical eccentric screw rod 1 is provided with tapered cap 3, tapered cap 3 inside are provided with the eccentric circular groove 4 of stepped shaft, the other end of conical eccentric screw rod 1 is threaded with stepped shaft nut 2, stepped shaft nut 2 is placed in the chute of motor; Wherein, the eccentric circular groove 4 of stepped shaft comprises big circular groove 4.1 and groove 4.2 compositions than small circular, and big circular groove is positioned at the center of tapered cap 3, is located at the eccentric position of circular greatly groove 4.1 than the groove 4.2 of small circular.
Because adopt tapered cap, common pipe wrench can't also just can't be dismantled its interlock, promptly rotatable, easy to operate during use by the spanner of the band stepped shaft eccentric lobe that is complementary with it, good anti-theft effect.
