Abstract
The present utility model relates to a nut with anti-looseness and anti-disassembly in the fastener field. It includes a nut body (1) and an anti-disassembly pin (2) and a nylon anti-looseness ring (3). It is characterized by that a pin layering (5) is set on the inner ring corresponding to the wedge groove (4) of said anti-looseness ring (3), said pin layering (5) and said anti-looseness ring (3) make the slip connection, on said pin layering (5) a roof block (6) extruding to the screw center is set. When said nut with anti-looseness and anti-disassembly is screwed on the bolt, in said roof block (6), the end roof can push directly the pin layering (5) out, and does not damage the anti-looseness ring (3), so the inner hole size of the nylon anti-looseness ring (3) can be set according to the requirement, and the anti-looseness ring (3) is not damaged so as to ensure the effective anti-looseness.
Description
Technical field
The utility model relates to the anti-loosing and anti-assembling nut in the fastener areas.
Background technique
At present, though use in the engineering or document in the bolt-type anti-loosing and anti-assembling nut introduced of a great variety, its structure is similar substantially, generally includes the anti-DNA releaxed circular DNA of nut, pin, nylon stopper and nylon.Vertically offer one or two one ends are obstructed and along being threaded into direction wedge slot from shallow to deep on the nut inner hole wall, anti-DNA releaxed circular DNA is fixedly installed on bolt and screws out on the screw wall of an end, and the plug closes that pin places wedge slot and is arranged on screw by interference fit therein.Though having solved early stage nut pin better, this structure is difficult for the problem that comes off easily in location, installation and the transportation process.But, for anti-loosing effect is preferably arranged, usually the internal orifice dimension outline that needs the anti-DNA releaxed circular DNA of nylon is less than screwhole diameter, making can have the power of an extruding and play locking effect after screwing in bolt bolt, but can cause to be subjected to when stopper is ejected by bolt in the installation process stopping of anti-DNA releaxed circular DNA like this, be difficult to smooth screw-in, screw in by force and may squeeze bad anti-DNA releaxed circular DNA again, thereby lose locking effect.
Summary of the invention
The purpose of this utility model is to provide a kind of screw-in smooth and easy, locking reliable anti-loosing and anti-assembling nut for overcoming the deficiencies in the prior art.
For achieving the above object, the technical solution that the utility model is taked is: anti-loosing and anti-assembling nut, comprise nut body, anti-pin and the anti-DNA releaxed circular DNA of nylon of unloading, it is characterized in that: the corresponding wedge slot of described anti-DNA releaxed circular DNA inner ring place is provided with the pin press strip, pin press strip and locking annulate shaft are to being slidingly connected, and described pin press strip is provided with the jacking block that protrudes to the screw center.
Because the corresponding wedge slot of the anti-DNA releaxed circular DNA inner ring place at anti-loosing and anti-assembling nut is provided with the pin press strip, pin press strip and locking annulate shaft are to being slidingly connected, the pin press strip is provided with the jacking block that protrudes to the screw center, when bolt screwed in, the termination withstood on the jacking block and can directly the pin press strip be ejected like a cork, screws in smooth and easy, can not damage anti-DNA releaxed circular DNA, therefore the internal orifice dimension of the anti-DNA releaxed circular DNA of nylon can be set as required, also can not squeeze bad anti-DNA releaxed circular DNA, thereby guarantee good locking effect.
The utility model is described in further detail below in conjunction with accompanying drawing and embodiment:

Embodiment
As Fig. 1, shown in Figure 2, anti-loosing and anti-assembling nut still comprises nut body 1, anti-retaining spare and the anti-DNA releaxed circular DNA 3 of nylon of unloading, the anti-retaining spare that unloads adopts pin 2, vertically offer half wedge slot 4 on the nut body 1 inner bolt hole wall, the bolt that opening end is arranged on nut screws out end, the number of wedge slot 4 can be provided with one or one or more on demand, generally too much unsuitable, offer two half wedge slots 4 in the present embodiment, wedge slot 4 is along being threaded into direction from shallow to deep, bolt screws out the end inner hole wall and is provided with the annular deep trouth 8 of a circle, the anti-DNA releaxed circular DNA 3 of nylon is embedded in annular deep trouth 8, as Fig. 3, shown in 4, the diameter of bore of the anti-DNA releaxed circular DNA 3 of nylon is slightly less than the inner bolt hole diameter, be provided with the chute 7 of axial perforation at the corresponding wedge slot of anti-DNA releaxed circular DNA 3 inner rings 4 places, chute 7 can be dovetail groove or shape groove, the degree of depth is slightly less than the maximum depth of wedge slot 4 to reserve the space of pin 2, pin press strip 5 cross sections and chute 7 match to be arranged on to constitute in the chute 7 and are in axial sliding connection, pin press strip 5 length can be equal to or slightly less than wedge slot 4 length, longly then can be exposed at outside the nut body 1, pin 2 places wedge slot 4 and pushes down fixing by pin press strip 5, the lower end of pin press strip 5 becomes L shaped formation jacking block 6 to the cross break of screw center, certainly jacking block 6 also can be arranged on other positions on the pin press strip 5, as middle part or middle and lower part.
Claims (2)
1, anti-loosing and anti-assembling nut, comprise nut body (1), anti-pin (2) and the anti-DNA releaxed circular DNA (3) of nylon of unloading, it is characterized in that: the corresponding wedge slot of described anti-DNA releaxed circular DNA (3) inner ring (4) locates to be provided with pin press strip (5), pin press strip (5) is in axial sliding connection with anti-DNA releaxed circular DNA (3), and described pin press strip (5) is provided with the jacking block (6) that protrudes to the screw center.
2, anti-loosing and anti-assembling nut according to claim 1, it is characterized in that: the corresponding wedge slot of described anti-DNA releaxed circular DNA (3) inner ring (4) locates to be provided with the chute (7) of axial perforation, described pin press strip (5) cross section and chute (7) match to be arranged on to constitute in the chute (7) and are slidingly connected, and the lower end cross break of pin press strip (5) becomes the described jacking block of L shaped formation (6).
