Abstract
The utility model discloses a kind of stop nuts of axis pin limiting, nut body and 2 pin shaft fixing seats including being equipped with threaded hole, 2 pin shaft fixing seats are symmetricly set on the bottom of nut body, the bottom symmetrical of the nut body is provided with the underlying T-slot of opening, the T-shaped slider extended in T-slot is respectively arranged on the pin shaft fixing seat, it is horizontally arranged with axis pin mounting hole respectively in 2 axis pin limit bases, the axis pin for being directed toward threaded hole center is respectively arranged in the axis pin mounting hole, one end that the axis pin is located in axis pin limit base is respectively arranged with the opposite semicircle tile of opening, the semicircle tile inner wall is respectively arranged with connection screw thread.The utility model pin shaft fixing seat is connect using the cooperation of T-shaped slider and T-slot with nut body, and the semicircle pocket set connected on axis pin circularizes card slot, and the bolt in nut is limited, locking on-slip, and anti-loosening property is relatively reliable.
Description
Technical field
The utility model is related to the stop nuts that fastener areas more particularly to an axis pin limit.
Background technology
General nut is standard component mostly currently on the market, itself does not prevent the function of loosening generally, therefore make
It is used cooperatively to reach locking purpose, not only in the process usually requiring that elastic washer for being adapted to nut etc. is in addition configured
Operating process is more complicated cumbersome, and anti-loosing effect is also undesirable, while also needs to expend a large amount of elastic washer, plain washer etc.
Mating fastener, production cost are higher.
Loosening can be generated by working in the environment of vibration and irregular fluctuation by the auxiliary connection of plain nut connection, sliding
It is de-, influence the reliability of connection, and the locking nut of rigid deformation, it is irreversible because deforming, it is generally used for the position do not dismantled company
It connects, auxiliary connection need to re-replace after dismounting, cause to waste.
Utility model content
The purpose of this utility model is to provide the stop nuts of axis pin limiting, and anti seismic efficiency is good, locking reliable lock
Tight nut, solve the problems, such as auxiliary connection easily loosened under threaded connection pair vibration environment, slippage.
For this purpose, the utility model uses following technical scheme：
A kind of stop nut of axis pin limiting, nut body and 2 pin shaft fixing seats including being equipped with threaded hole, described 2
A pin shaft fixing seat is symmetricly set on the bottom of nut body, and the bottom symmetrical of the nut body is provided with opening and is located at lower section
T-slot, the T-shaped slider extended in T-slot is respectively arranged on the pin shaft fixing seat, in 2 axis pin limit bases
It is horizontally arranged with axis pin mounting hole respectively, the axis pin for being directed toward threaded hole center is respectively arranged in the axis pin mounting hole, it is described
One end that axis pin is located in axis pin limit base is respectively arranged with the opposite semicircle tile of opening, in the semicircle tile
Wall is respectively arranged with connection screw thread.
Wherein, the T-slot bottom end is provided with the positioning bolt of fixed T-shaped slider.
Wherein, T-shaped slider machine-shaping integrated with axis pin limit base.
Wherein, elastic rubber layer is pasted and is provided on the connection screw thread surface.
Wherein, the thickness of the elastic rubber layer is 0.4mm.
The beneficial effects of the utility model：
First, reliable lock, shock-proof check, tight lock part design screw clamping distance by axis pin in pin shaft hole, according to
By two semicircle round sets of tiles composition, to go deep into the bolt in nut limit it is locking；
2nd, can Reusability, convenient disassembly is cost-effective, and axis pin keeps original function, while screw thread will not be caused
Permanent damage is realized and is reused, maintains easily demand.
Description of the drawings
Fig. 1 is the structure diagram of the utility model.
Specific embodiment
The technical solution of the utility model is further illustrated with reference to Fig. 1 and by specific embodiment.
A kind of stop nut of axis pin limiting, nut body 1 and 2 pin shaft fixing seats 2 including being equipped with threaded hole 11, institute
The bottom that 2 pin shaft fixing seats 2 are symmetricly set on nut body 1 is stated, the bottom symmetrical of the nut body 1 is provided with opening position
T-slot 12 in lower section is respectively arranged with the T-shaped slider 21 extended in T-slot 12, installation speed on the pin shaft fixing seat 2
Degree is fast, and structural strength is high, is horizontally arranged with axis pin mounting hole in 2 axis pin limit bases 2 respectively, in the axis pin mounting hole
The axis pin 3 for being directed toward 11 center of threaded hole is respectively arranged with, one end that the axis pin 3 is located in axis pin limit base 2 is set respectively
The opposite semicircle tile 4 of opening is equipped with, semicircle 4 inner wall of tile is respectively arranged with connection screw thread, two semicircles watt
Piece 4 is combined into a round set, and the bolt in nut is fixed on the positioning.
In the present embodiment, 12 bottom end of T-slot is provided with the positioning bolt 5 of fixed T-shaped slider 21, and convenient disassembly is fast
Speed.
In the present embodiment, the T-shaped slider 21 and 2 integrated machine-shaping structural strength of axis pin limit base height are light-weight.
In the present embodiment, elastic rubber layer 6, the thickness of the elastic rubber layer 6 are pasted and be provided in the connection screw thread surface
It spends for 0.4mm, the enclasping force between the semicircle tile 4 of increase and bolt improves frictional resistance, so as to play the role of loosening.
In above-mentioned, the semicircle tile 4 is threadably secured by axis pin 3 along axis pin mounting hole, is realized to bolt
Fastening promotes anti-loosening property.
More than content is only the preferred embodiment of the utility model, for those of ordinary skill in the art, according to this reality
With novel thought, there will be changes, the content of the present specification should not be construed as in specific embodiments and applications
Limitation to the utility model.
