Tool for quickly disassembling and assembling stud bolt

Technical Field

The utility model belongs to the technical field of mechanical assembly, concretely relates to quick assembly disassembly stud's instrument.

Background

Most of places using stud all are the connection of casing, all will use sealed glue to carry out the sealed of casing under the majority condition, and the screw hole department of using sealed glue rear housing all can glue a certain amount of sealed glue, and stud just more difficult when the dismouting like this can use two spanners to screw up or screw down with two nuts locking back reuse spanner, does so and wastes time and energy.

SUMMERY OF THE UTILITY MODEL

The utility model overcomes prior art exists not enough, provides a quick assembly disassembly stud's instrument.

In order to solve the technical problem, the utility model discloses a technical scheme be: a quick-disconnect stud tool comprising: pull ring, handle, cam, fixed plate, base, nut, connecting axle and curved surface groove, the axial is vertical places the upper end coaxial fixation of nut has columniform the base, the upper end symmetry of base is fixed with two vertical settings the fixed plate, two be provided with between the fixed plate the cam, the cam pass through the connecting axle with the fixed plate is connected, the cam can be relative the connecting axle rotates, the cam below seted up on the base with the cam suits the curved surface groove works as when the cam convex surface is down, the cam with base laminating and chucking, cam one side is fixed with the handle, the other end of handle is fixed with the pull ring.

The middle part in curved surface groove is provided with sectorial card protruding, card protruding with fixed plate parallel arrangement, the convex surface one end of cam seted up with the protruding compatible draw-in groove of card, card protruding with the draw-in groove cooperation is used for increasing this instrument and supports when applying torsion, and increases cam drive firmness when the nut is rotatory.

The nut and the stud bolt have the same specification.

The fixing plate is provided with a through hole through which the connecting shaft penetrates, and the fixing plate is fixed with the connecting shaft.

Compared with the prior art, the utility model following beneficial effect has.

One, the utility model relates to a simply small and exquisite, loosen nut on the stud or pull down, then on twisting the screw rod of screw with the nut of this instrument, with cam locking back, alright relaxed twist the stud from the casing and twist off, installation or dismantlement that can be quick in stud dismouting in-process are very practical.

Two, the utility model discloses be provided with the protruding and draw-in groove of card that suits on cam and the curved surface groove, further increase the fastness behind this instrument cam locking.

Detailed Description

The following is a further description with reference to specific examples.

A quick-disconnect stud tool comprising: pull ring 1, handle 2, cam 3, fixed plate 4, base 5, nut 6, connecting axle 8 and curved surface groove 10, the axial is vertical places the upper end coaxial of nut 6 is fixed with columniform base 5, the upper end symmetry of base 5 is fixed with two vertical settings fixed plate 4, two be provided with between the fixed plate 4 cam 3, cam 3 pass through connecting axle 8 with fixed plate 4 is connected, cam 3 can be relative connecting axle 8 rotates, the cam 3 below seted up on the base 5 with cam 3 suits curved surface groove 10 works as 3 convex surface of cam is down the time, cam 3 with 5 laminating and chucking of base, 3 one side of cam is fixed with handle 2, the other end of handle 2 is fixed with pull ring 1.

Curved surface groove 10's middle part is provided with sectorial protruding 9 of card, card protruding 9 with fixed plate 4 parallel arrangement, cam 3's convex surface one end seted up with card protruding 9 adapted draw-in groove 7, card protruding 9 with draw-in groove 7 cooperation is used for increasing the support when this instrument applys torsion, and increases cam 3 drive firmness when nut 6 is rotatory.

The nut 6 and the stud bolt have the same specification.

The fixing plate 4 is provided with a through hole through which the connecting shaft 8 penetrates, and the fixing plate 4 is fixed with the connecting shaft 8.

The nut on the stud bolt is loosened or detached, then the nut of the tool is screwed on the screw rod of the screw, the stud bolt can be easily screwed on the shell and screwed off after the cam is locked, and meanwhile, the straight rod can be adopted to penetrate through the pull ring, so that the rotary stress application of the device is more convenient.

The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. It will be apparent to those skilled in the art that modifications and improvements can be made to the above-described embodiments without departing from the spirit and scope of the invention.
