Abstract
The piston opener in use for antitheft device for transformer includes hollow outer cover, hollow threaded rod, nut, and bolt. Being cooperated to locking head on the antitheft device tightly, clip is setup at tail part of the outer cover. Threaded rod is fixed on head part of the outer cover, and the bolt runs through the said outer cover and threaded rod. Being cooperated to screw hole on the piston of the antitheft device, screw thread is setup at tail part of the bolt. The nut is installed on the threaded rod. Working travel of the nut is larger than distance between the nut and the head part of the threaded rod. The threaded rod and the outer cover are formed in integration. Being installed on bolt, bearing is located between threaded rod and head part of the bolt. Using outer cover to clip the locking head, the invention fixes bolt and piston, and rotating nut can pull out piston. Features are: simple, easy of use, long service life.
Description
(1) technical field
The present invention relates to the piston opener that a kind of anti-theft device for transformer is used.
(2) background technology
The piston of existing anti-theft device for transformer, original opening ways all are to adopt one piece of fin neck bolt thimble, utilize screw thread backspin principle, and the reservation screw that is provided with in the middle of the logical piston in top after thimble pushes up other objects, extrudes piston work relax is opened at last.This open method clumsiness, non-science, and make thimble screw thread or the anti-tooth of piston intermediate thread are easily opened dumbly, and thimble uses a secondary just to scrap, the use cost height, and the life-span is short.
(3) summary of the invention
For the piston that solves existing anti-theft device for transformer open clumsy, open the high shortcoming of cost, the invention provides a kind of easy to use, can repeatedly use, piston opener in use for installation in transformer for guarding against theft with low cost.
The technical solution used in the present invention is for this reason:
A kind of piston opener in use for installation in transformer for guarding against theft includes hollow outer cover, hollow screw, nut, bolt, and described outer cover afterbody is provided with the bayonet socket with the tapered end snap-fit of anti-theft device; Described screw rod is fixed in the outer cover head, and described outer cover of bolt-through and screw rod, the afterbody of described bolt are provided with the screw thread that cooperates with the screwed hole of anti-theft device upper piston; Described screw rod is provided with external screw thread, and nut is installed on the described screw rod, and described nut is provided with the internal thread that cooperates with described screw rod; The impulse stroke of described nut is greater than the distance of nut and screw head.
Further, described screw rod and outer cover are one-body molded.
On the described bolt bearing is installed, described bearing is between screw rod and bolt head.
Described outer cover is brachycephalic or bell jar type.
The invention has the beneficial effects as follows: 1, outer cover blocks tapered end, fixes by bolt and piston, and the rotation nut is extracted piston, and is simple in structure, easy to use; 2, can use repeatedly, long service life, with low cost.
(4) description of drawings
Fig. 1 is an initial condition schematic diagram of the present invention;
Fig. 2 is the working state schematic representation of nut of the present invention when supporting firm bearing, bearing and supporting firm bolt head.
(5) embodiment
With reference to accompanying drawing 1,2, a kind of piston opener in use for installation in transformer for guarding against theft includes hollow outer cover 2, hollow screw 8, nut 3, bolt 7, and described outer cover afterbody is provided with the bayonet socket 1 with the tapered end snap-fit of anti-theft device; Described screw rod is connected the outer cover head, and described screw rod and outer cover are one-body molded; Described outer cover of bolt-through and screw rod, the afterbody of described bolt are provided with the screw thread 9 that cooperates with the screwed hole of anti-theft device upper piston; Described screw rod is provided with external screw thread, and nut is installed on the described screw rod, and described nut is provided with the internal thread that cooperates with described screw rod; The impulse stroke of described nut is greater than the distance of nut and screw head.Bearing 4,5,6 is installed on the described bolt, and described bearing is between screw rod and bolt head.Described outer cover can be brachycephalic or bell jar type.
Operation principle of the present invention is as follows: regulate bolt, make bolt tail and piston affixed; Then to the inner rotary nut, when nut and bearing offset, after bearing supports firm bolt head again, continue the rotation nut, piston can be extracted with the opener one.
