Description

With the truck cab rear support of rear latch hook

Technical field

The utility model relates to a kind of lorry accessory, specifically refers to a kind of truck cab rear support with rear latch hook.

Background technology

Girder of truck bottom existing truck cab is all provided with the mechanisms such as oil cylinder, for when needs keep in repair parts such as motortruck engine, can, by overall for the operator's compartment of lorry jack-up, makes it maintain rollover open mode.On the other hand, in order to ensure truck cab when normal traveling can safety locking on girder of truck, girder of truck bottom existing truck cab is provided with buckle lock truck cab, this buckle structure is fairly simple, its opening and closing need people's manual manipulation completely, and, in order to ensure the locking intensity of buckle, strength required for the opening and closing of its buckle is comparatively large, opens and operate more difficult.

In addition, this buckle is generally all arranged on girder of truck by rear support, but existing lorry rear support is relatively simple for structure, does not have buffering and damping effect, have impact on the travelling comfort of operator's compartment.

Summary of the invention

The purpose of this utility model is the shortcoming and defect existed to overcome prior art, and provides a kind of conveniently opening and closing flexibly and have the truck cab rear support with rear latch hook of buffering and damping effect.

For achieving the above object, include rear support, this rear support includes mount pad, be fixed on the main pivot shaft on mount pad, also include rear latch hook, one end of described main pivot shaft is hinged is fixedly installed bumper, this rear latch hook includes latch hook support, latch hook support internal fixtion arranges inner fixed stand, described inner fixed stand is provided with the adapter plate of two interval symmetries that are parallel to each other, between these two adapter plates, internal fixtion is provided with two the first anchor shafts and the second anchor shaft be parallel to each other, on the first described anchor shaft, interlock is fixedly installed the first dead bolt, the second described anchor shaft rotates and is provided with the second dead bolt, this first anchor shaft has been fixed by socket the first torsion spring, the outer end withstand effect of this first torsion spring is on inner fixed stand, the second described anchor shaft has been fixed by socket the second torsion spring, the outer end of this second torsion spring acts on the second dead bolt, the first described dead bolt is provided with the first inner groovy, the lower end profile of relative first inner groovy of this first dead bolt is provided with the first arcuate guide wall, the second described dead bolt is provided with the second arcuate guide wall coordinated that to lead with the first arcuate guide wall of the first dead bolt, on this second dead bolt, the outer end of relative second arcuate guide wall is provided with the second inner groovy, this second inner groovy forms anchor ear district with the first inner groovy when the two is relative, described inner fixed stand is provided with the hydraulic piston contrary with the second torsion spring force direction of the second dead bolt relative to the bottom pushing tow of the second dead bolt, described latch hook support is provided with the latch hook supporting plate of two opposing parallel interval symmetries, all be fixedly installed latch hook between the corner, front and back of these two latch hook supporting plates and anchor shaft is installed, these two latch hooks are installed anchor shaft and are fixedly connected with the outer end of bumper with the outer end of main pivot shaft respectively.

By this setting, rear latch hook is installed between main pivot shaft and the outer end of bumper, the damping support to rear latch hook can be realized thus, damping, buffering is effective, and this arranges rear latch hook, under the effect at the first torsion spring and the second torsion spring of the first dead bolt and the second dead bolt, the first inner groovy and the second inner groovy is kept mutually to stagger in state of nature, namely after, latch hook is in open mode, when needs are opened rear latch hook, hydraulic piston pushing tow second dead bolt, make, first inner groovy and the second inner groovy are oppositely arranged, form anchor ear district, thus the lock shaft on operator's compartment is placed in anchor ear district, form the locking to operator's compartment, this setting, open and close without the need to manpower completely, operate very easily laborsaving, and adopt the locking of hydraulic piston, its locking intensity is very good, ensure the safety locking of operator's compartment.

Further setting is that described bumper includes damper shaft, slippage is arranged at bumper pressure cap on damper shaft, and two ends are limited in the recoil spring between bumper pressure cap and damper shaft respectively.This setting, vibrational power flow is simple, and cost is low, easy to assembly.

In sum, the utility model has the advantages that damping, buffering is effective, and rear latch hook 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.
