Description
Technical field
It the utility model is related to light, microcaloire car self-unloading cargo box structure, and in particular to a kind of slag-soil truck container tail door headstock gear
Structure.
Background technology
At present, common light, microcaloire car slag-soil truck container tail door mechanism for opening/closing mainly has drag hook type, lock posture and rod-pulling type
Three kinds.Wherein, drag hook type is mainly overturn by drag hook, forms the locking with latch and relieving acts, reach the mesh of back door keying
, it is easy to operate, can effectively it operate.But when latch is welded to connect with back door, welding surface is small, intensity is weak, welding operation difficulty is big,
Latch cantilever is long at the same time, and latch easily deforms in actual use, or even fractures；Lock posture by straight curved lock frame with
Locking and the relieving action of buckle, achieve the purpose that back door opens and closes, but since straight curved lock frame is in opening, often due to gravity
Or packing case lifting vibration and whirlpool down downwards so that influence in addition interfere back door keying, to operation and use bring inconvenience,
Seldom producer uses this structure；Rod-pulling type passes through pull rod（Some uses hinge）Folding and unfolding, makes briquetting compress and decontrol back door, reaches
The purpose opened and closed to back door.Engineering dregs car container use at present is more universal, but manufacture is of high cost, and mechanism for opening/closing is relatively multiple
It is miscellaneous, if poor fit between structure（It is stuck）, back door cannot effectively open when easily causing packing case lifting, so as to trigger accident.
Utility model content
The utility model overcomes the deficiencies in the prior art, there is provided a kind of easy to operate, non-damageable slag-soil truck of structure
Container tail door mechanism for opening/closing.
The utility model is realized by the following technical solutions：
Slag-soil truck container tail door mechanism for opening/closing, including：
Switching arm of the container lower end at tail-gate is hinged on by axis pin；
It is arranged on the driving mechanism that container lower end is used to drive the switching arm to rotate；
Be arranged on the cover for seat of container rear end, be fitted with U-shaped latch in the cover for seat, the lower end of the U-shaped latch with it is described
The upper arm of switching arm holds tactile；
It is arranged on the fixing sleeve of tail-gate side, the upper end of the U-shaped latch is inserted in described under tail-gate locking states
In fixing sleeve；
It is wrapped in the compression spring between cover for seat and U-shaped latch lower end on the U-shaped latch.
Further, the container lower end offers skewed slot at tail-gate, and the switching arm is arranged in the skewed slot.
Further, the working end of the driving mechanism is connected with the first ball, first ball and the switching arm
Lower arm contact.
Further, the lower end of the U-shaped latch is provided with the second ball, and the compression spring wrap is in cover for seat and second
On U-shaped latch between ball, the upper arm of second ball and the switching arm holds tactile.
Further, limiting slot is offered in the cover for seat, the part that the U-shaped latch is located in cover for seat is provided with guiding
Muscle, the guiding rib are slided in the limiting slot.
Further, the driving mechanism is one kind in oil cylinder either cylinder.
The beneficial effects of the utility model are：
1st, the utility model promotes switching arm rotation by driving mechanism, and then drives U-shaped latch oscilaltion to realize goods
The keying of case tail-gate, it is ensured that during the daily loading of container, tail-gate is effectively locked；During lifting, tail-gate is opened（Upset）Freely, solve
Slight at present, card automobile dregs container is often with mechanism for opening/closing is complicated, cost is higher, easily triggers stuck series of problems.
2nd, the utility model is provided with switching arm, and switching arm is flexibly connected with driving mechanism using ball, avoids container
Because the vibrations of U-shaped latch cause driving mechanism to bear extra impact force during jolting, driving mechanism is effectively protected.
3rd, the utility model is provided with compression spring on the U-shaped latch of the lower end of cover for seat, by the compression spring, can make
The upper end for obtaining U-shaped latch is securely inserted into the non-working status of driving mechanism in the fixing sleeve, is avoided because of container
Jolt " out of stock " accident of initiation.
Brief description of the drawings
Fig. 1 is the utility model structure diagram.
Embodiment
Below in conjunction with the accompanying drawings and embodiment is described further the utility model.
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation
Example, is further elaborated the utility model.It should be appreciated that specific embodiment described herein is only explaining this
Utility model, is not used to limit the utility model.
As shown in Figure 1, the utility model discloses a kind of slag-soil truck container tail door mechanism for opening/closing, including：Cut with scissors by axis pin 4
It is connected on switching arm 5 of 1 lower end of container at tail-gate 2；It is arranged on the drive that 1 lower end of container is used to drive the switching arm 5 to rotate
Motivation structure 3,3 preferred oil cylinder of driving mechanism either cylinder；The cover for seat 6 of 1 rear end of container is arranged on, U is fitted with the cover for seat 6
Type latch 7, the lower end of the U-shaped latch 7 and the upper arm of the switching arm 5 hold tactile；It is arranged on the fixing sleeve 8 of 2 side of tail-gate, institute
The upper end for stating U-shaped latch 7 is inserted under tail-gate locking states in the fixing sleeve 8；It is upper to be wrapped in the U-shaped latch 7
Compression spring 9 between 7 lower end of cover for seat 6 and U-shaped latch.
For the ease of installing switching arm, skewed slot is opened up at tail-gate 2 in 1 lower end of container, the switching arm 5 is arranged on
In the skewed slot.
Cause driving mechanism 3 impaired because latch loosens when jolting in order to avoid container, connected in the working end of driving mechanism 3
First ball 30, first ball 30 are contacted with the underarm of the switching arm 5 with a surface state pattern.Similarly, it is described U-shaped
The lower end of latch 7 is provided with the second ball 70, and the upper arm of second ball 70 and the switching arm 5 holds tactile；Second ball 70
The lower end of U-shaped latch 7 is threaded in, has a diameter larger than the diameter of U-shaped 7 lower end of latch, while also greater than the internal diameter of cover for seat 6,
In this way it can be ensured that U-shaped latch 7 will not be skidded off from cover for seat 6.
In order to ensure the upper end of U-shaped latch 7 opens and closes in the fixing sleeve 8 exactly, opened up in the cover for seat 6 limited
Position groove, the part that the U-shaped latch 7 is located in cover for seat 6 are provided with guiding rib, and the guiding rib is slided in the limiting slot.
In order to ensure U-shaped latch 7 will not be out of stock and in order to make U-shaped latch 7 reliably insert fixation because container jolts
Set 8, the compression spring 9 being wrapped on U-shaped latch 7 is provided with the lower end of the cover for seat 6.
As shown in Figure 1, during utility model works, driving mechanism 3 is released, and promotes switching arm 5 to rotate counterclockwise, switching arm
5 upper arm rotates up, and promotes U-shaped latch 7 to move up, so that 7 upper end of U-shaped latch departs from fixing sleeve 8, realizes tail-gate
2 unlatching；When needing locking, driving mechanism 3 is retracted, effect return of the U-shaped latch 7 due to compressing spring 9 so that U-shaped latch 7
In fully-inserted fixing sleeve 8.
Above-described embodiment is the preferred embodiment of the utility model, is not the limit to technical solutions of the utility model
System, as long as the technical solution that can be realized without creative work on the basis of above-described embodiment, is regarded as falling into
In the rights protection scope of the utility model patent.
