Description
Technical field
Lifting machine technical field is the utility model is related to, especially a kind of mousing-hook safeties.
Background technology
In hoisting process, suspended object or connector are deviate from from suspension hook in order to prevent, usually in the increase of suspension hook opening
Insurance card is used for anticreep, and general insurance card is generally made of card body, spring, bolt, nut, and part is more, is not easily assembled, and
In use due to frequent dislodging hook after installation, insurance card is easily loose, insurance card is failed and lifting danger occurs.
Utility model content
This patent utility model aims to overcome that above shortcomings and deficiencies of the prior art, develops a kind of mousing-hook and protects
Dangerous device, mousing-hook safeties can be fixed together with the axis pin of suspension hook, of simple structure and strong practicability, more security insurance.
The utility model is using following technical scheme realization, a kind of mousing-hook safeties, including anti-off board, suspension hook
Axis pin, nut and compression spring, the anti-off board include vertical portion and oblique stopper, and the vertical portion is connected with suspension hook axis pin one end, position
In suspension hook opening side, the tiltedly stopper is connected with vertical portion lower end, is obliquely installed, and keeps off in suspension hook aperture position, it is described vertically
Subordinate end is equipped with positioning protrusion towards suspension hook side, and locating slot is equipped with the positioning protrusion matching suspension hook；The suspension hook pin
The axis other end is equipped with external screw thread, and on the outside of the suspension hook pin shaft hole on suspension hook, nut, the spiral shell are mutually equipped with the external screw thread
It is female the suspension hook axis pin is set between the suspension hook pin shaft hole to be equipped with compression spring.
Preferably, the nut is hexagonal locking nut.
The beneficial effect of the utility model mousing-hook safeties：
1) axis pin of this mousing-hook safeties and suspension hook is fixed together, of simple structure and strong practicability；
2) other end of suspension hook axis pin extends and added with compression spring, only need to laterally promote axis and axial-rotation, you can adjustment is anti-
Unhook safe position, plays suspension hook mousing-hook function, easy to operate, using flexible；
3) there is location structure on mousing-hook safeties, be adjusted in place and match afterwards with the position portion on suspension hook, adjust
It is accurate in place, prevent rotary shifted rear failure, more security insurance.
Brief description of the drawings
Further illustrate with reference to the accompanying drawings and detailed description：
Fig. 1 is the structure diagram of the utility model mousing-hook safeties.
Embodiment
As shown in Figure 1, the utility model discloses a kind of mousing-hook safeties, including anti-off board 3, suspension hook axis pin 2, spiral shell
Mother 4 and compression spring 1, anti-off board 3 link together with suspension hook axis pin 2, are inserted into suspension hook pin hole, pressure is loaded onto in 2 extension of axis pin
Spring 1, finally loads onto hexagonal locking nut 4 in 2 end of axis pin.The anti-off board includes vertical portion 7 and oblique stopper 8, the tiltedly gear
Portion 8 is connected with 7 lower end of vertical portion, is obliquely installed, and keeps off and being set in 5 aperture position of suspension hook, 7 lower end of vertical portion towards suspension hook side
There is positioning protrusion, locating slot 6 is equipped with the positioning protrusion matching suspension hook 5.
The utility model discloses mousing-hook safeties, the present apparatus can be fixed together with the axis pin of suspension hook, structure letter
It is single.
The application method of the utility model mousing-hook safeties：Axis 2, anti-off board 3 and the positioning on suspension hook 5 are promoted forward
Groove 6 separates, at the same to the left or to the right rotate anti-off board 3, by anti-off board 3 go to top, at this time anti-drop device open, suspended object or
Connector can be linked into or be taken off suspension hook 5；Anti-off board 3 is conversely pivotally lowered into underface, is loosed one's grip at the same time, in the pressure of compression spring 1
Power lower bearing pin 2 is moved rearwards together with anti-off board 3, and anti-off board 3 is contacted with the position portion 6 on suspension hook 5 coincide, and is adjusted at this time
Position, anti-drop device closure, suspended object or connector can not take out in suspension hook 5, play anti-off effect.
The utility model mainly realizes the anti-drop function of suspension hook suspended object or connector.
Finally it should be noted that：The above descriptions are merely preferred embodiments of the present invention, is not limited to this
Utility model, although the utility model is described in detail with reference to the foregoing embodiments, for those skilled in the art
For, it can still modify the technical solution described in foregoing embodiments, or to which part technical characteristic
Carry out equivalent substitution.Where within the spirit and principles of the present invention, any modification, equivalent replacement, improvement and so on,
It should be included within the scope of protection of this utility model.
