Description
Technical field
The present invention relates to a kind of screw, more particularly to a kind of tight screw of speed.
Background technology
Existing screw includes screw rod, nut and pad, is the physics of the inclined-plane circular rotating and frictional force that utilize object
And mathematical principle, the instrument of implements parts are fastened by easy stages, it is impossible to reach the effect of quick locking.Consolidate for cabinet
Fixed, cabinet even shields, or is inconvenient under the occasion of spanner using just very inconvenient.
The content of the invention
It is an object of the invention in view of the above-mentioned problems, providing a kind of tight screw of speed.
Therefore, the technical solution adopted in the present invention is：A kind of tight screw of speed, including screw body and nut, its feature
It is：The position of one end end away from nut is provided with the sky that can accommodate a pair of butterfly-type Anti-skid sheets in the screw body
Chamber, the strip through-hole stretched out for butterfly-type Anti-skid sheet is had in the opposite sides side wall of the screw body, described in a pair
One end of the remote nut of butterfly-type Anti-skid sheet is close and is rotatably connected on respectively by rotational pin in cavity, close to one end of nut
Separate, and stretched out respectively from the strip through-hole of both sides, this between butterfly-type Anti-skid sheet by " u "-shaped shell fragment to being connected, when through even
When connecing hole and being squeezed, a pair of butterfly-type Anti-skid sheets collapse into cavity, and when extruding eliminates, a pair of butterfly-type Anti-skid sheets outwards deploy,
Anti-slop serrations are provided with the end face of one end of the close nut of the butterfly-type Anti-skid sheet.
In the place for being inconvenient to spanner, a pair of butterfly-type Anti-skid sheets can pass through the connecting hole of two articles, smoothly logical
After crossing connecting hole, flicked under the effect of " u "-shaped shell fragment, only need one (side), with regard to that can tighten, to play quick locking using spanner
Effect, it is easy to use, installation effectiveness is improved, the problem for solving blind hole connection (or opposite can not go spanner to fasten).
In such scheme：Anti-slop serrations are provided with the upper surface of the butterfly-type Anti-skid sheet.Avoid locking from skidding, improve locking
Power, ensure the reliability of locking.
In such scheme：The screw body is conical screw.
In such scheme：There is spring shim close to nut overcoat on the screw body.In the case where being acted on from card spring shim,
Anti-slop serrations is attached to piece surface, with screwing for nut, compress two parts for needing to connect.
It is preferred that：Pad is also cased with outside the screw body, the pad is between spring shim and nut.
The beneficial effects of the invention are as follows：The fast tight bolt of the present invention, can quickly play a part of quick locking, it is only necessary to one
Head uses spanner, and the suitable place use for being inconvenient to spanner is simple in construction, reasonable in design.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention.
Fig. 2 is side view.
Embodiment
By way of example and in conjunction with the accompanying drawings, the invention will be further described：
Embodiment 1
The tight screw of one kind speed as illustrated in fig. 1 and 2 is by screw body 1, butterfly-type Anti-skid sheet 2, " u "-shaped shell fragment 3, nut 4, pad
Piece 5, spring shim 6 form.
Screw body 1 is conical screw.Nut 4 is cased with the larger diameter end of screw body 1.Close to spiral shell on screw body 1
Pad 5 is cased with outside mother 4.Spring shim 6 is also cased with outside screw body 1, pad 5 is between spring shim 6 and nut 4.
A pair of butterflies can be accommodated by being provided with screw body 1 close to the position of one end end (smaller diameter end) away from nut 4
The cavity of type Anti-skid sheet 2, had in the opposite sides side wall of screw body 1 and stretch out strip through-hole for butterfly-type Anti-skid sheet 2,
The lower end root (one end away from nut) of a pair of butterfly-type Anti-skid sheets 2 is close and is rotatably connected on cavity by rotational pin respectively
Interior, top separates (close to one end of nut), and is stretched out respectively from the strip through-hole of both sides, i.e., a pair of butterfly-type Anti-skid sheets 2 are in
"eight" shape is separated, and this between butterfly-type Anti-skid sheet 2 by " u "-shaped shell fragment 3 to being connected, and when depressed, a pair of butterfly-type are anti-skidding
Piece 2 collapses into cavity, and when extruding eliminates, a pair of butterfly-type Anti-skid sheets 2 outwards deploy, and the upper surface of butterfly-type Anti-skid sheet 2 is (close to spiral shell
Female one end end face) on be provided with anti-slop serrations 2a, anti-slop serrations 2a can be set clockwise or counterclockwise.
The present invention is not limited to above-mentioned specific embodiment, it will be appreciated that one of ordinary skill in the art is without creative
Work can makes many modifications and variations according to the design of the present invention.In a word, all technician in the art are according to this
The design of invention passes through the available technical side of logical analysis, reasoning, or a limited experiment on the basis of existing technology
Case, all should be in the protection domain being defined in the patent claims.
