Specific embodiment
Specific introduce is made to the present invention below in conjunction with the drawings and specific embodiments.
As shown in Figures 1 to 6, a kind of adjustable latch dismounting structure 100, comprising: bar 10 of pulling pin, 20 and of jack
Screw head 30.Screw head 30 is used to screw in the threaded hole of latch to be constituted connection with latch.Jack 20 includes: pressing plate 21
With hydraulic cylinder 22.Bar 10 of pulling pin is connected to screw head 30.Pressing plate 21 is slided relative to hydraulic cylinder 22 to drive bar 10 of pulling pin to move.
Adjustable latch dismounting structure 100 further include: locating rod 40.Locating rod 40 is for fixed bar 10 and the pressure of pulling pin
The relative position of plate 21.Locating rod 40 is articulated to pressing plate 21.Bar 10 of pulling pin is formed with multiple locating slots 11.Locating slot 11 is used
In the relative position for locking pull pin bar 10 and pressing plate 21 with the cooperation of locating rod 40.Screw head 30 is detachably connected to bar of pulling pin
10.Bar 10 of pulling pin is formed with card slot 12.Screw head 30 is formed with mounting blocks 31.Mounting blocks 31 are used to make screw rod with the cooperation of card slot 12
First 30 are detachably connected with bar 10 of pulling pin.By the cooperation of multiple locating slots 11 and locating rod 40, it is effectively increased jack
20 stroke eliminates the inconvenience for needing to increase cushion block, can accomplish to improve working efficiency when pulling pin with with tune.
As a kind of specific embodiment, card slot 12 is located at the one end for bar 10 of pulling pin.It is remote that card slot 12 is located at bar 10 of pulling pin
One end from locating slot 11.Mounting blocks 31 are driven to transport for contacting with mounting blocks 31 specifically, the cell wall of card slot 12 is formed with
