Description
Technical field
The present invention relates to lifting machine technical field, especially a kind of mousing-hook safeties.
Background technology
In hoisting process, in order to prevent suspended object or connector from deviating from from suspension hook, generally in the increase of suspension hook opening
Insurance card is used for anticreep, and general insurance card is typically made up 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.
The content of the invention
Invention aims to overcome that above shortcomings and deficiencies of the prior art, develops a kind of mousing-hook insurance dress
Put, mousing-hook safeties can be fixed together with the bearing pin of suspension hook, simple in construction, practical, more security insurance.
The present invention is using following technical scheme realization, a kind of mousing-hook safeties, including anti-off board, suspension hook pin
Axle, nut and stage clip, the anti-off board include vertical portion and oblique stopper, and the vertical portion is connected with suspension hook bearing pin one end, is located at
Suspension hook opening side, the tiltedly stopper are connected with vertical portion lower end, are obliquely installed, keep off in suspension hook aperture position, the vertical portion
Lower end is provided with positioning convex towards suspension hook side, and locating slot is provided with the positioning convex matching suspension hook；The suspension hook bearing pin
The other end is provided with external screw thread, and on the outside of the suspension hook pin shaft hole on suspension hook, nut, the nut are mutually equipped with the external screw thread
The suspension hook bearing pin is set between the suspension hook pin shaft hole and is provided with stage clip.
Preferably, the nut is hexagonal locking nut.
The beneficial effect of mousing-hook safeties of the present invention：
1) bearing pin of this mousing-hook safeties and suspension hook is fixed together, simple in construction, practical；
2) other end of suspension hook bearing pin extends and added with stage clip, only need to laterally promote axle and axial-rotation, you can adjustment is anti-
Unhook safe position, play suspension hook mousing-hook function, simple to operate, using flexible；
3) there is location structure on mousing-hook safeties, be adjusted in place and matched 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 structural representation of mousing-hook safeties of the present invention.
Embodiment
As shown in figure 1, the invention discloses a kind of mousing-hook safeties, including anti-off board 3, suspension hook bearing pin 2, nut 4
With stage clip 1, anti-off board 3 links together with suspension hook bearing pin 2, inserts suspension hook pin hole, stage clip 1 is loaded onto in the extension of bearing pin 2,
Finally hexagonal locking nut 4 is loaded onto in the end of bearing pin 2.The anti-off board includes vertical portion 7 and oblique stopper 8, the tiltedly stopper 8 with
The lower end of vertical portion 7 is connected, and is obliquely installed, and keeps off in the aperture position of suspension hook 5, it is fixed that the lower end of vertical portion 7 is provided with towards suspension hook side
Position is raised, and locating slot 6 is provided with the positioning convex matching suspension hook 5.
The invention discloses mousing-hook safeties, the present apparatus can be fixed together with the bearing pin of suspension hook, simple in construction.
The application method of mousing-hook safeties of the present invention：Axle 2, anti-off board 3 and the locating slot 6 on suspension hook 5 are promoted forward
Separation, while anti-off board 3 is rotated to the left or to the right, anti-off board 3 is gone into top, now anti-drop device is opened, suspended object or company
Fitting can be linked into or be plucked from suspension hook 5；Anti-off board 3 is conversely pivotally lowered into underface, loosed one's grip simultaneously, in the pressure of stage clip 1
Lower bearing pin 2 is moved rearwards together with anti-off board 3, and anti-off board 3 contacts with the position portion 6 on suspension hook 5 coincide, and is now adjusted in place,
Anti-drop device closes, and suspended object or connector can not take out in suspension hook 5, plays anticreep effect.
The main anti-drop function for realizing suspension hook suspended object or connector of the invention.
Finally it should be noted that：The preferred embodiments of the present invention are the foregoing is only, are not intended to limit the invention,
Although the present invention is described in detail with reference to the foregoing embodiments, for those skilled in the art, it still may be used
To be modified to the technical scheme described in foregoing embodiments, or equivalent substitution is carried out to which part technical characteristic.
Within the spirit and principles of the invention, any modification, equivalent substitution and improvements made etc., it should be included in the present invention's
Within protection domain.
