Description
[technical field]
The utility model relates to link technical field, particularly relates to a kind of removable locking lifting bolt.
[background technique]
Lifting bolt uses very extensive in electronic product, its turn is very convenient, but traditional lifting bolt mostly is monolithic construction, each several part is not removable, kind because of screw thread has a lot, during assembling, the screw thread of lifting bolt must unanimously with the screw thread of product can assemble, therefore producer needs according to product situation before completed knocked down products, purchase the lifting bolt matched in advance, work operation is heavy, lifting bolt function singleness, design impersonality, and without any locking functions, there is potential safety hazard in existing lifting bolt.
[model utility content]
The purpose of this utility model overcomes the deficiencies in the prior art, provides one and detachably to change the outfit lifting bolt.
The utility model is achieved through the following technical solutions: one detachably changes the outfit lifting bolt, comprise screw, pad, post block, annulus, described screw front end is the ailhead arranging screw thread, rear end is screwed cylinder, and the screw thread of ailhead is contrary with the thread rotary orientation of cylinder, described cylinder is arranged in the central post holes of post block, the outside thread of cylinder and the internal thread of central post holes match, check washer is arranged between described screw and post block, described post block is connected with annulus, described circular annulus is arranged several circular holes; Described check washer comprises the first packing ring and the second packing ring, and the second packing ring is all identical with the shape size of the first packing ring; First packing ring and the second packing ring fit together, and two surfaces that two packing rings contact are respectively arranged with interlaced radial sawtooth, and two packing rings are closely meshed together by described surface of contact sawtooth; The shape of described surface of contact sawtooth is made up of two planes, and one of them plane orthogonal is in reference level, and the angle of another plane and reference level angle is greater than the angle of screw thread on ailhead, and described reference level is the plane at the first packing ring and the second place, washer contacts face; Surface of contact sawtooth arranged counterclockwise, the first packing ring and the non-touching outer surface of the second packing ring arranges tiny radially outer surface sawtooth respectively, outer surface sawtooth arranged clockwise; The shape of outer surface sawtooth is identical with the shape of surface of contact sawtooth, and the size of outer surface sawtooth is less than surface of contact sawtooth.
As optimal technical scheme of the present utility model, described screw front end ailhead arranges dissimilar screw thread, and screw is replaceable.
As optimal technical scheme of the present utility model, the quantity of described surface of contact sawtooth is 4-20, and the quantity of described outer surface sawtooth is 1-4 times of the quantity of surface of contact sawtooth.
At use removable locking lifting bolt of the present utility model, on the one hand, because the screw thread of ailhead is contrary with the screw thread rotation direction of cylinder, screw and post block can be prevented and wait that lifting electronic product gets loose simultaneously; On the other hand, because two packing rings are engaged each other by surface of contact sawtooth, the outer surface sawtooth laminating post block of the first packing ring, the outer surface sawtooth of the first packing ring is fitted and is waited to lift electronic product, post block can be prevented and wait that relative rotation occurs each other to lift electronic product, thus playing anti-loosing effect.In addition, front end screw can be changed according to thread type, improve assembling applicability of the present utility model.
Compared with prior art, the beneficial effects of the utility model are: the utility model structure is simple, reasonable in design, low cost of manufacture, can change front end screw according to thread type, in addition, the utility model has anti-loosing effect, can prevent in hoisting process because of lifting bolt with treat lift electronic product and cause the two mutually to depart from because occurring to loosen, and then initiation security incident.
