Abstract
The invention discloses a cab locking device assembly which comprises a locking hook, a locking matching plate and a shell, wherein the locking hook and the locking matching plate are fixed inside the shell through a pin shaft, the locking hook can rotate along the pin shaft and match with the locking matching plate to lock or release a lock shaft, and the locking device assembly is arranged on a vehicle body through a first shaft hole and a second shaft hole on the shell. The invention has simple structure, convenient installation, and safe and reliable locking.
Description
Technical field
The present invention relates to a kind of blocking device, particularly a kind of cab locking device that on the side of chassis, locks the tiltable operator's compartment.
Background technology
Motor car engine is the heart of self-propelled vehicle, and is most important to its maintenance and repair.The operator's compartment of truck is to be fixed on the chassis basically, but and driving engine is mounted on the chassis of under-cab, be conventional maintenance, the repairing that makes things convenient for driving engine, driver's cab turnover need be tilted.Tiltable operator's compartment also needs locking when lowering position, when making travelling truck on the bevelled road, operator's compartment does not turn over before not understanding.Existing blocking device mainly adopts rotating latch hook to hook lock shaft and locks, and each parts are installed in the assembly that forms blocking device on the stay bearing plate, and parts such as latch hook all are exposed to outer damage easily, install also more loaded down with trivial details.
Summary of the invention
The objective of the invention is to overcome above-mentioned shortcoming of the prior art, cab locking device assembly a kind of simple in structure, easy for installation is provided.
A kind of cab locking device assembly of the present invention, comprise lock hook, lock board, housing, described lock hook and lock board are fixed in the housing by bearing pin, described lock hook can rotate along bearing pin, matching with lock board locks lock shaft or unclamps, and described locking device assembly is installed on the car body by first axis hole on the housing and second axis hole.
In a preferred embodiment of the invention, the position of the position of described first axis hole and the croisillon de joint homocinetique of fixedly locked matching board overlaps, and croisillon de joint homocinetique is a hollow shaft.
In a preferred embodiment of the invention, return spring also is housed on the bearing pin of described lock hook, described return spring one end hook is lived lock hook, and an end hook is lived second bearing pin.
In a preferred embodiment of the invention, the position of the position of described second axis hole and second bearing pin overlaps, and second bearing pin is a hollow shaft.
In a preferred embodiment of the invention, the material of described lock hook, lock board and housing is a steel plate.
In a preferred embodiment of the invention, described lock hook is made up of the identical steel plate stack of the shape more than with lock board.
It is simple in structure that the present invention compares its advantage with the prior art scheme, easy for installation, locks safe and reliable.
Description of drawings
Fig. 1 is an embodiment of the present invention structural representation;
Structural representation when Fig. 2 is Fig. 1 embodiment lock-out state.
Among the figure: 1 is lock hook; 2 is lock board; 3 is housing; 4 is first bearing pin; 5 is return spring; 6 is second bearing pin (second axis hole); 7 is torsion spring; 8 is croisillon de joint homocinetique (first axis hole); 9 is the 4th bearing pin; 10 is bolt; 11 is the 5th bearing pin; 12 is lock shaft.
The specific embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present invention is described in detail, thereby protection scope of the present invention is made more explicit defining so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that.
As Fig. 1 in conjunction with shown in Figure 2, present embodiment comprises lock hook 1, lock board 2, housing 3, described lock hook 1 is fixed on the housing 3 by first bearing pin 4, and lock hook 1 can rotate around first bearing pin 4, thereby cooperation locks lock shaft 12 or unclamps with lock board; Lock board is to be fixed on the housing by croisillon de joint homocinetique 8, lock board 2 fixing can not rotations, present embodiment is to produce opposite effect power by symmetrical torsion spring 7 on the croisillon de joint homocinetique 8 and bolt 10, thereby lock board can not be rotated along croisillon de joint homocinetique 8.Can fix with other mode, the present invention does not limit yet.
Be with a return spring 5 on first bearing pin 4, described return spring 5 one end hooks are lived lock hook 1, one end hook and are lived second bearing pin 6.When lock hook rotates, produce the return pulling force, when lock hook unlocks, under the return tension that return spring 5 produces, automatically revert to original state, thereby lock shaft 12 is gone out of lock.
Described second bearing pin 6 and croisillon de joint homocinetique 6 are hollow shafts, and described locking device assembly can be installed on the operator's compartment of vehicle by described axis hole.
Described housing 3 can be stamped to form with steel plate, and is easy to process for making, and can be combined to form for several block plates.
Described lock hook 1 and lock board 2 can be stamped to form with steel plate, for gaining in strength, can be formed by stacking with several block-shaped identical steel plates.
