Abstract
The utility model provides a kind of tight mechanism of self-discharging carriage rear-door automatic locking, comprise latch hook, chain, one end of chain is connected with latch hook, other one section is connected on subframe afterbody crossbeam, also include attaching parts, spring, the both sides of attaching parts are provided with axis hole, spring is arranged on the both sides of latch hook, two springs respectively stretch out neck and the leg that a section is stuck in latch hook, latch hook and spring are fixed together by bearing pin and attaching parts, the head of latch hook is provided with lock crook plate, and attaching parts is fixed on cabin floor lower end.Use the tight mechanism of self-discharging carriage rear-door automatic locking described in the utility model, adopt single latch hook, there will not be locking asynchrony phenomenon, adopt the effect that spring automatically replies, reliably can lock it after dump truck cabin rear door is closed, ensure the tight requirements of car body loading, there is structure simple, stable performance, feature easy to maintenance, service life is greatly improved.
Description
Technical field
Basis is practical relates to a kind of automobile bodies, especially a kind of tight mechanism of self-discharging carriage rear-door automatic locking.
Background technology
Tradition locking device of rear door of dumper is all adopt double-lock hook structure, namely two latch hooks are contained in the both sides at back door respectively, this catch gear is after vehicle period of service has been grown, there will be the situation of two latch hook distortion, two latch hooks will be caused like this to open and lock asynchronous, side locking opposite side is not locked, and vehicle half of for carriage back door plate crimp, can cause a hidden trouble to the transportation safety of dumping car when fully loaded material.
The catch gear just simple effect relying on Action of Gravity Field to reach opening and closing usually of existing self dumping lorory back door jack, reaction is slow, and coupling mechanism force is inadequate, and the time has grown easy inefficacy.
Summary of the invention
The purpose of this utility model is to provide a kind of tight mechanism of self-discharging carriage rear-door automatic locking, can solve double-lock hook and easily produce and open closed nonsynchronous problem, and be swift in response, coupling mechanism force is large, long service life and installing easily.
In order to solve the problems of the technologies described above, the technical solution of the utility model is as follows: the tight mechanism of self-discharging carriage rear-door automatic locking, comprise latch hook, chain, one end of chain is connected with latch hook, other one section is connected on subframe afterbody crossbeam, it is characterized in that: also include attaching parts, spring, the both sides of attaching parts are provided with axis hole, spring is arranged on the both sides of latch hook, two springs respectively stretch out neck and the leg that a section is stuck in latch hook, latch hook and spring are fixed together by bearing pin and attaching parts, the head of latch hook is provided with lock crook plate, attaching parts is fixed on cabin floor lower end.
Improvement to technique scheme: the level height of described subframe afterbody crossbeam is higher than the lower end of the latch hook be connected with chain.
Beneficial effect:
Use the tight mechanism of self-discharging carriage rear-door automatic locking described in the utility model, adopt single latch hook, there will not be locking asynchrony phenomenon, adopt the effect that spring automatically replies, reliably can lock it after dump truck cabin rear door is closed, ensure the tight requirements of car body loading, there is structure simple, stable performance, feature easy to maintenance, service life is greatly improved.
Accompanying drawing explanation
Fig. 1 is front view of the present utility model.
Fig. 2 is upward view of the present utility model.
Fig. 3 is structural representation of the present utility model.
In figure: lock crook plate 1, latch hook 2, attaching parts 3, spring 4, bearing pin 5, chain 6.
Detailed description of the invention
The tight mechanism of the utility model self-discharging carriage rear-door automatic locking as shown in Figure 1, Figure 2, Figure 3 shows, comprises lock crook plate 1, latch hook 2, attaching parts 3, spring 4, bearing pin 5, chain 6.Two springs, latch hook 2 are fixed together by bearing pin 4 by attaching parts 3, and lock crook plate 1 is welded on latch hook 2 head, and attaching parts 3 upper end is welded on base plate lower end.Two springs respectively stretch out neck and the leg that a section is stuck in latch hook 2, and one end of chain 6 is connected with latch hook 2, and other one section is connected on subframe afterbody crossbeam.The level height of subframe afterbody crossbeam is higher than the lower end of the latch hook 2 be connected with chain 6.
During the non-lifting in compartment, by the locking effect of spring 3, be pressed on by lock crook plate on Rear Door, realize locking, now chain is in relaxed state.During carriage lifting, base plate rear end moves down, and chain is strained gradually, until opened by latch hook, back door is opened.When compartment declines, base plate rear end rises, and chain relaxes gradually, and spring automatically replies, and again realizes locking effect, and back door is closed.
