Description
Technical field
The utility model is related to the technical field of tablet self-discharging semitrailer rear car door locking structure, particularly it is a kind of it is new after
Door latch apparatus.
Background technology
For the haulage vehicle in communications and transportation and engineering machinery, generally using dump type truck carriage, to ensure cargo security,
Dump type truck carriage is usually mounted with locking device, and the locking device of truck compartment rear door is manual locking device.However, manual locking is locked
The shortcomings that tight is：It is complicated, maintenance cost is high, poor reliability, the labor intensity of operating personnel are big.In addition, after the loading space
Door lock clamp force deficiency, easily loosens when shaking, and the Lou pollution such as slag environment is easily caused there is a phenomenon where back door not tight.
Tablet self-discharging semitrailer includes girder, auxiliary girder and container, and auxiliary girder is installed at the top of girder, and container includes tablet and case
Body, babinet are fixedly arranged on the top of tablet, and the opening of babinet is hinged with tail gate, and manual locking device is installed on tail gate,
Tail gate is lock onto on babinet through locking device, and tablet is installed on auxiliary girder through axis pin.When being unloaded, it is necessary to open locking
The dregs that container could be lifted after device makes it internal pours out, and after opening, substantial amounts of dregs comes down in torrents, very dangerous.
Utility model content
The purpose of the utility model is to overcome the shortcomings that the prior art, there is provided a kind of compact-sized, coupling mechanism force is greatly, steadily
Discharging, safe and reliable new type back door blocking device.
The purpose of this utility model is achieved through the following technical solutions：A kind of new type back door blocking device, it includes master
Beam, container, the auxiliary girder being arranged on girder, container are made of tablet and babinet, and babinet is installed on flat plate top, box opening
Tail gate is hinged with, the rearward end of tablet is installed on auxiliary girder through shaft rotation, and lock is provided with the rearward end of the tablet
Button, latches the shape that takes the shape of the letter U, and the left plate of lock is articulated with the rearward end of tablet through axis pin A, and the right plate of lock presses tail gate
Outer end face, is installed with hinge seat on the girder, horizontally disposed pull rod is hinged with hinge seat, the other end of pull rod is sold
Axis B is articulated with the bottom of lock.
The bottom of the tail gate is installed with hyoplastron.
The hyoplastron is arranged between the left side plate of lock.
The right plate of the lock is pressed on hyoplastron.
The utility model has the following advantages：The utility model is compact-sized, coupling mechanism force is big, steady discharging, safe and reliable.
Brief description of the drawings
Fig. 1 is the structure diagram of the utility model
In figure, 1- girders, 2- tablets, 3- babinets, 4- tail gates, 5- shafts, 6- locks, 7- axis pins A, 8- hinge seat, 9-
Pull rod, 10- axis pins B, 11- hyoplastron.
Embodiment
The utility model is further described below in conjunction with the accompanying drawings, the scope of protection of the utility model be not limited to
It is lower described：
As shown in Figure 1, a kind of new type back door blocking device, it includes girder 1, container, the auxiliary girder being arranged on girder 1,
Container is made of tablet 2 and babinet 3, and babinet 3 is installed on the top of tablet 2, and 3 opening of babinet is hinged with tail gate 4, tablet 2
Rearward end is installed on auxiliary girder through the rotation of shaft 5, is provided with lock 6 in the rearward end of the tablet 2, and lock 6 takes the shape of the letter U shape,
The left plate of lock 6 is articulated with through axis pin A7 in the rearward end of tablet 2, and the right plate for latching 6 presses 4 outer end face of tail gate, institute
Hinge seat 8 is installed with the girder 1 stated, horizontally disposed pull rod 9 is hinged with hinge seat 8, the other end of pull rod 9 is through axis pin
B10 is articulated with the bottom of lock 6.
As shown in Figure 1, the bottom of the tail gate 4 is installed with hyoplastron 11, the hyoplastron 11 is arranged at a left side for lock 6
Between right plate, the right plate of the lock 6 is pressed on hyoplastron 11.
The course of work of the utility model is as follows：Under original state, lock 6 latches 6 under the pulling force effect of pull rod 9
Right plate is tightly pressed on the hyoplastron 11 of tail gate 4 all the time, even if road jolts, dregs or material in babinet 3 can not also leak
Go out, have the characteristics that coupling mechanism force is big.When to be unloaded, start the main lifting cylinder on lorry, lifting cylinder makes tablet 2 around turning
Axis 5 does clockwise rotation, and in rotation process, pull rod 9 is rotated clockwise around hinge seat 8, while latches 6 around axis pin
A7 is rotated clockwise, and hyoplastron 11 is separated with the right plate of lock 6, and the opening formed between the two gradually increases, thing in babinet 3
Material or dregs slowly pour out, rather than largely come down in torrents, and have the characteristics that safe and reliable.
