Abstract

The present invention relates to a tailgate lock device for tightly adhering a stacker and a tailgate in a compressed vehicle so that there is no leakage of wastewater, and the gate cylinder (4) for opening and closing the tailgate (2) from the stacker (1). The lock rod piece 10 which is movably installed in the rear frame 5 and the piston rod 4a of the () is connected so that the lock of the rear end portion 10a is moved as the lock rod piece 10 moves upward. The projections 12 and 12 'are pulled while being caught by the lock grooves 21 provided in the lock pieces 22 and 22' of the lock hole 20 attached to both sides of the lower end 2a of the tailgate 2. As the tailgate 2 is locked with a strong adhesion in the loading box 1 direction, it prevents the leakage of wastewater and facilitates the locking and releasing operation of the tailgate.

The present invention relates to a tailgate lock device of a compressed vehicle to keep the tailgate and the storage box in close contact so that the sewage in the compressed vehicle compartment is not leaked to the outside during operation.

In general, the compressed and extracted vehicle is a garbage collection vehicle, so that the sewage from the kitchen trash is present in the loading bin. If the wastewater is leaked to the outside during the operation or during the garbage collection, the problem of causing bad smell and serious street hygiene is caused. .

Therefore, it is possible to prevent the leakage of waste sewage by making the close contact between the loading box of the compressed vehicle and the TALE GATE to be in close contact, but in the conventional lock method in which the tail gate is in close contact with the loading box, the manual handle operation method is used. The locking device of the system was mainly utilized, which caused very troublesome and inconvenient problems.

Therefore, in the past, when the tailgate is strongly locked, it is difficult to later release it, so that the operator frequently locks the vehicle properly and drives the vehicle frequently. Therefore, the tailgate is operated so that the tailgate is not in close contact with the loading box. Wastewater is leaking into roads, causing odor and unsanitary waste disposal.

The purpose of the present invention is to provide a tailgate lock device that has no conventional waste leakage in the red container in consideration of the conventional problems as described above, and another object thereof is to automatically lock and unlock the tailgate. The aim is to provide easier tailgate locking and unlocking by providing tailgate locks.

In order to achieve the above object, the present invention works in conjunction with the gate cylinder to provide a lock device in which the tailgate is locked and released.

Therefore, the lock device of the present invention is to be made of a structure that is locked while the pulling force is applied so that the tailgate is in close contact with the loading box strongly at the final moment of the process that the Kate cylinder is operated to lower the tailgate, Based on the embodiment and described in more detail as follows.

FIG. 1 shows a compressed vehicle according to the present invention, in which 1 is a loading box and 2 is a tailgate that is rotated about a gate hinge axis 3 to move up and down.

The tail gate 2 is lifted when the piston rod 4a of the gate cylinder 4 installed at both sides is moved forward, so that the garbage in the stacking box 1 can be discharged to the outside, and the piston rod 4a. ) Is to be reversed to move down and close close to the loading box 1 as shown in the solid line of FIG. Therefore, the present invention is installed to be movable in the longitudinal direction on the long lock rod piece 10 inside the rear frame 5 on both sides of the loading box 1, the cylinder connecting piece 11 of the lock rod piece 10 is the rear frame ( 5) to protrude to the outside through the rate of the long hole (6) drilled in the open while the rear end (10a) protruding to both sides of the lock projection (12, 12 ') is installed so as to be exposed to the lower rear frame (5) The middle portion of the rod piece 10 is provided with a locking piece 13 so as to be moved at a constant moving distance in the moving hole 7.

Since the rear frame 5 is generally manufactured in a quadrangular shape, the rear frame 5 may be inserted and installed so that the lock rod piece 10 can be moved therein, and the cylinder connecting piece 11 protruding to the outside through the long hole 6 may have a gate. The piston rod 4a of the cylinder 4 is installed to be connected.

On the other hand, on both sides of the lower end portion (2a) of the tail gate (2) so that the lock hole 20 is formed between the pair of lock pieces 22, 22 'having the lock groove 21 rate is formed in the insertion groove 23 It is.

In the figure, reference numeral 8 denotes a discharge plate, 8a denotes a discharge cylinder, and 9 denotes a packing.

In this configuration, the discharge plate 8 is virtually discharged by the discharge cylinder 8a after the tailgate 2 is lifted up as shown in FIG. The waste gas is discharged by being moved as shown in the drawing. At this time, the gate cylinder 4 is in a state in which the piston rod 4a is moved forward (see an imaginary line in FIG. 5 (A)). After the waste discharge in the stacking box 1 is completed, when the piston rod 4a of the gate cylinder 4 is operated backward, the tailgate 2 is rotated about the gate hinge shaft 3 and lowered to stack the stacking box 1. When the rear end 10 of the lock rod piece 10 is inserted into the insertion groove 23 of the lock hole 20, the lock protrusions 12, 12 ′ are locked by the lock pieces 22, 22. ') Is inserted into the lock groove 21 of. In this state, the piston rod 4a is not fully retracted and has an extra working distance for reversing.

Therefore, when the piston rod 4a of the gate cylinder 4 is further retracted in the state in which the lock protrusions 12 and 12 'are rotated in the lock groove 21 of the lock pieces 22 and 22', from this time on, Since the tail gate 2 is in contact with the loading box 1, the lock rod piece 10 connected to the cylinder connecting piece 11 is upwardly oriented as shown in the solid line in FIG. 5 (B). It will be pulled slightly to move.

Therefore, the subject of the present invention is that the locking protrusions 12 and 12 'of the rear end portion 1a are caught by the lock groove 21 by the upward movement of the lock rod piece 10 as described above. ) Is pulled up, and the pulling action is applied to the tailgate 2 to be pulled toward the stacking box 1 by this pulling force.

Therefore, as described above, when the locking operation of the tailgate 2 is completed, the tailgate 2 is strongly pressed against the packing 9, thereby maintaining a strong locking state.

On the other hand, the unlocking of the tail gate (2) is to advance the piston rod (4a) roll of the gate cylinder (4) to open the tail gate (2) for waste discharge, the piston rod before the tail gate (2) is raised Due to the forward movement of (a), the lock rod piece 10 is first moved downward so that the strong pull force is released and the tailgate 2 is immediately raised.

According to the above description, since the tailgate lock device is linked and automatically made according to the operation of the existing gate cylinder 4 operated in the driver's seat, not only does it provide a simple operation but also a relatively simple structure. Because it is not concerned about the failure and pulls the tailgate close to the loading box by hydraulic pressure rather than manually operated force, it provides an effect that prevents the leakage of more perfect waste.
