Description
Technical field
It the utility model is related to fork truck part, and in particular to a kind of fork truck retaining mechanism.
Background technology
Fork truck belongs to construction machinery industry, due to the particularity of working space, has to overall dimensions of a car and mobility very high
It is required that so requiring that overall dimensions of a car is as far as possible small when designing vehicle, closely, the arrangement of parts is compressed as far as possible in space
Space, can not also take larger space for the locking device of car door, and locking selectable currently on the market at present
Device volume is larger, or the gravity switch requirement that can not meet fork truck car door again of small volume.
Utility model content
The purpose of this utility model is that providing one kind is suitable to fork truck tight space requirements, meets the lock of fork truck use demand
Tight mechanism.
To achieve the above object, the utility model employs following technical scheme：
A kind of fork truck retaining mechanism, including on fixed support and mutually ratcheting left lock body and right lock body, with
And the lock pin on lock bracket, the lockpin hole being engaged with the lock pin is offered on the right lock body；The fixation
It is installed with support shaft on support, lever plate is arranged with by sliding bearing in the support shaft, the rear end of the lever plate is against
The lower end of left lock body.
Further scheme, the front end of the lever plate are connected with push pedal, push down on push pedal and drive lever plate and sliding axle
Hold and rotated together around support shaft, so as to promote left lock body to drive right lock body together to move clockwise.
Further scheme, torsion spring is equipped with the support shaft between fixed support and sliding bearing, the torsion spring
Two torque arm are connected with fixed support, lever plate respectively.
Further scheme, the left lock body, right lock body are arranged on fixed support by fixing axle respectively.
It is that fixed support is secured by bolts in car door, lock bracket leads to during retaining mechanism installation of the present utility model
Cross bolt to be fixed on vehicle frame, when door closing, the lockpin hole on right lock body is buckled in the lock pin on lock bracket, lock pin
Motive force makes left lock body be rotated counterclockwise with right lock body respectively around respective fixing axle, finally ratcheting by lock with left and right lock body
Pin card is lived, so as to complete the locking of car door.
When needing opening car door, then push pedal is pushed down on, push pedal drives the lever plate action being secured to together, thick stick
Bar plate is rotated by sliding bearing around support shaft, makes bottom and the right lock body of left lock body so as to promote left lock body to move upwards
Separation, front end drive right lock body to rotate clockwise and remove lockpin hole, and lock pin just separates from lockpin hole, and realizes opening for car door
Open.Then push pedal is unclamped, the screen resilience for the torsion spring being installed in support shaft is put on lever plate, makes lever plate together with push pedal
Return, complete whole breakdown action.
Locking mechanism structure of the present utility model is compact, small volume, and operation is simple and reliable for open and close, meets that fork truck makes
With requiring.
So the retaining mechanism of utility model is fully being assessed in car door on the premise of space, from better suited lock
Body, preferred arrangement support, lever plate and push pedal, support shaft, sliding bearing, the structure of torsion spring, and completed through checking repeatedly.
Brief description of the drawings
Fig. 1 is locking schematic diagram of the present utility model；
Fig. 2 is unlatching schematic diagram of the present utility model；
Fig. 3 is support shaft connection diagram in the utility model.
In figure：1- fixed supports, the left lock bodies of 2.1-, 2.2- right lock bodies, 2.3- lockpin holes, 3- lever plates, 4- push pedals, 5-
Lock bracket, 6- support shafts, 7- sliding bearings, 8- torsion springs, 9- fixing axles, 10- fixing bolts, 11- lock pins.
Embodiment
The utility model is described further below in conjunction with the accompanying drawings：
As Figure 1-3, a kind of fork truck retaining mechanism, including on fixed support 1 and mutually ratcheting left lock
Body 2.1 and right lock body 2.2, and the lock pin 11 on lock bracket 5, offer and the lock on the right lock body 2.2
The lockpin hole 2.3 that pin 11 is engaged；Support shaft 6 is installed with the fixed support 1, passes through sliding bearing 7 in the support shaft 6
Lever plate 3 is arranged with, the rear end of the lever plate 3 is against the lower end of left lock body 2.1.
Further scheme, the front end of the lever plate 3 are connected with push pedal 4 by fixing bolt 10, push down on the band of push pedal 4
Dynamic lever plate 3 and sliding bearing 7 rotate around support shaft 6 together, and promote left lock body 2.1 to drive the together up time of right lock body 2.2
Pin moves.
Further scheme, torsion spring 8, the torsion are equipped with the support shaft 6 between fixed support 1 and sliding bearing 7
Two torque arm of spring 8 are connected with fixed support 1, lever plate 3 respectively.
Further scheme, the left lock body 2.1, right lock body 2.2 are arranged on fixed support 1 by fixing axle 9 respectively.
It is that fixed support 1 is secured by bolts in car door during installation, lock bracket 5 is secured by bolts on vehicle frame,
When door closing, the lockpin hole 2.3 on right lock body 2.2 is buckled in the lock pin 11 on lock bracket 5, and the motive force of lock pin 11 makes
Left lock body 2.1 rotates counterclockwise with right lock body 2.2 respectively around respective fixing axle 9, finally ratcheting by lock pin with left and right lock body
