Abstract
The utility model discloses a truck cab rear latch hook which comprises a latch hook support. An inner fixed support is fixedly arranged in the latch hook support. Two installation plates which are symmetrically arranged in parallel at intervals are arranged on the inner fixed support. A first inner groove is formed in a first spring bolt, a first arc guide wall is arranged on the lower end outline of the first spring bolt opposite to the first inner groove, a second arc guide wall matched with the first arc guide wall of the first spring bolt is arranged on the second spring bolt, a second inner groove is formed in the outer end of the second spring bolt opposite to the second arc guide wall, the second inner groove and the first inner groove form a hoop area when facing each other, a hydraulic piston is arranged at the bottom of the inner fixed frame opposite to the second spring bolt in a pushing mode, and the action force direction of the hydraulic piston is opposite to that of a second torsion spring. The truck cab rear latch hook has the advantage of being convenient and flexible to open and close and good in locking strength.
Description
Technical field
The utility model relates to a kind of rear latch hook of truck cab.
Background technology
On the girder of truck of existing truck cab bottom, be all provided with the mechanisms such as oil cylinder, for when needs keep in repair parts such as motortruck engine, can, by the whole jack-up of the operator's compartment of lorry, make it maintain rollover open mode.On the other hand, for ensure truck cab can safety locking when normally travelling on girder of truck, on the girder of truck of existing truck cab bottom, being provided with buckle locks truck cab, this buckle structure is fairly simple, it opens and closes needs people's manual manipulation completely, and, in order to ensure the locking intensity of buckle, the needed strength of opening and closing of its buckle is larger, opens and operate more difficult.
Summary of the invention
The purpose of this utility model is the shortcoming and defect existing in order to overcome prior art, and a kind of conveniently opening and closing latch hook after truck cab is flexibly provided.
For achieving the above object, the technical solution of the utility model is to include latch hook support, in latch hook support, be fixedly installed inner fixed stand, on described inner fixed stand, be provided with the adapter plate of two interval symmetries that are parallel to each other, in between these two adapter plates, be fixedly installed two the first anchor shafts that are parallel to each other and the second anchor shaft, on the first described anchor shaft, interlock is fixedly installed the first dead bolt, on the second described anchor shaft, rotate and be provided with the second dead bolt, on this first anchor shaft, be fixed by socket the first torsion spring, the outer end withstand effect of this first torsion spring is on inner fixed stand, on the second described anchor shaft, be fixed by socket the second torsion spring, the outer end of this second torsion spring acts on the second dead bolt, on the first described dead bolt, be provided with the first inner groovy, on the lower end profile of relative the first inner groovy of this first dead bolt, be provided with the first arcuate guide wall, on the second described dead bolt, be provided with the second arcuate guide wall coordinating with the first arcuate guide wall guiding of the first dead bolt, on this second dead bolt, the outer end of relative the second arcuate guide wall is provided with the second inner groovy, this second inner groovy forms anchor ear district when the two is relative with the first inner groovy, the bottom pushing tow of relative the second dead bolt of described inner fixed stand is provided with the hydraulic piston contrary with the second torsion spring force direction of the second dead bolt.
By this setting, at the first dead bolt and the second dead bolt under the effect of the first torsion spring and the second torsion spring, in state of nature, keep the first inner groovy and the second inner groovy mutually to stagger, after, latch hook is in open mode, when needs are opened rear latch hook, hydraulic piston pushing tow the second dead bolt, make, the first inner groovy and the second inner groovy are oppositely arranged, form anchor ear district, thereby the lock shaft on operator's compartment is placed in anchor ear district, the locking of formation to operator's compartment, this setting, completely without manpower opening and closing, operate very easily laborsaving, and the locking of employing hydraulic piston, its locking intensity is very good, ensured the safety locking of operator's compartment.
Further arranging is on described latch hook support, to be provided with the latch hook supporting plate of two opposing parallel interval symmetries, is fixedly installed latch hook anchor shaft is installed between the corner of these two latch hook supporting plates.By this setting, this latch hook is installed anchor shaft and conveniently the utility model is fixed on the girder of truck of operator's compartment bottom.
In sum, the utility model has the advantages that conveniently opening and closing is flexible, locking intensity is good.
Below in conjunction with specification drawings and specific embodiments, the utility model is described further.
Accompanying drawing explanation
Fig. 1 the utility model specific embodiment structural representation;
Fig. 2 the utility model specific embodiment STRUCTURE DECOMPOSITION figure;
Fig. 3 the first dead bolt and the second dead bolt coordinate schematic diagram.
