Abstract
The invention discloses a rear manipulated saddle, and especially to a rear manipulated saddle connecting a tractor and a semi-trailer. The rear manipulated saddle provided by the invention comprises a lock hook, a lock latch and a manipulation handle arranged inside a machine base. The machine base is provided with a traction pin introducing port and a traction pin arrangement hole. The lock hook comprises a long hook handle, a short hook handle and a base part. The lock hook is provided with a pivot fixed on the machine base. A lock hook extension spring is arranged on one side of the machine base near the short hook handle so that the lock hook can rotate around the pivot. The lock latch comprises a hinged end and a free end. The lock latch is arranged below the lock hook. The hinged end of the lock latch is hinged to the manipulation handle. When the lock latch is pulled away from the traction pin introducing port by the manipulation handle, the lock hook rotates, the short hook handle of the lock hook surmounts the traction pin introducing port, and the long hook handle of the lock hook is stopped by the free end of the lock latch and abuts against the free end of the lock latch, thus the coupling and separation on the tractor and the semi-trailer are realized. The rear manipulated saddle provided by the invention has the advantages of reasonable structure, simple process, low cost, simple operation and high safety performance.

The specific embodiment
Below pass through the specific embodiment, and the invention will be further described by reference to the accompanying drawings.
As shown in Fig. 1,2,3,4,5, the present invention discloses a kind of rear manipulation saddle, comprises support 1 and is arranged on latch hook 2, lock bolt 3 and the handlebar 4 in support 1.Support is provided with towing pin introducing port 9 and towing pin mounting hole 8.Latch hook is provided with fulcrum 12 and is fixed on support 1, and the base portion 23 of latch hook is provided with latch hook extension spring 5 near a side of the short neck of hook 21 can rotate around fulcrum 12 latch hook 2, and one end of handlebar 4 and lock bolt 3 are hinged, and support 1 is provided with chute, and lock bolt 3 moves in chute.Handlebar 4 is L shaped structures.On handlebar 4, be provided with de-hang spacing 41 and pull spacing 42, by the stretching of handlebar 4 is carried out tractor truck with the coupling of superimposed trailer with separated.When the towing pin 11 of superimposed trailer enters the towing pin mounting hole 8 of rear manipulation saddle, latch hook extension spring 5 is shunk, and the short neck of hook 21 of latch hook 2 is resisted against on lock bolt 3, handles extension spring 6 thereupon and shrinks, handlebar 4 pull spacing 42 indentation, there that are fixed on support 1, realized the coupling of tractor truck and superimposed trailer.On the handle 7 of the extraneous application of force at handlebar 4, handle extension spring 6 and stretch, latch hook extension spring 5 stretches thereupon, makes the long neck of hook 22 of latch hook be resisted against the free end 31 of lock bolt, the de-extension spacing 41 of handlebar is fixed on the indentation, there of support 1, thereby realizes the separated of tractor truck and superimposed trailer.The cost of this rear manipulation saddle is low, technique is simple, simple to operate, safety performance is high.
The design of handlebar is exquisite to be de-ly to hang spacing 41 and pull spacing 42 setting, can after to handle 4 application of forces, utilize the draw and shrink of handling extension spring 6 to make its spacing indentation, there that is fixed on exactly support 1.
The wedge-shaped design of the short shank of the key 21 of latch hook is that towing pin 11 turnover towing pin mounting holes 8 are more smooth, and the introducing port 9 of towing pin enters towing pin mounting hole 8 larger scope is provided for open form enlarging is gradually designed to towing pin 11.The design of the combination of the free end 31 of lock bolt, the shank of the key length of latch hook and adjusting screw(rod) 10, has improved the safety performance of rear manipulation saddle.
In order to further illustrate each mode of operation of rear manipulation saddle, applicant provide saddle pulling, the handlebar schematic diagram of pre-hung, de-extension state, shown in Figure 6, at the state of pulling, towing pin 11 is fixed in the towing pin mounting hole 8 of support 1 by pin hook 2.The short neck of hook 21 of latch hook 2 is resisted against on lock bolt 3, the free end 31 of lock bolt 3 is conditioned screw rod 10 one end restriction sites, pin jointed end 32 and the handlebar 4 of lock bolt 3 are hinged, and handlebar 4 shrinks by handling extension spring 6, and de-extension spacing 41 is accurately fixed in the breach of support.Realize the coupling of handling saddle and tractor truck after tractor truck.
Shown in Figure 7, extension spring 6 stretching handlebars 4 are handled in extraneous application of force utilization, and de-extension spacing 41 is fixed in the breach of support 1.Lock bolt 3 is subject to the traction of handlebar 4, and toward moving left, lock bolt 3 is disconnected from each other with latch hook 2, is now in pre-hung state.
Shown in Figure 8, when the state of pre-hung, latch hook 2 is subject to latch hook extension spring 5 and shrinks, and is pulled, and along fulcrum 12, rotates.The short shank of the key 21 of latch hook is crossed towing pin introducing port 9, and the long shank of the key 22 of latch hook is by free end 31 backstops of lock bolt and be resisted against the free end 31 of lock bolt, and towing pin 11 departs from the restriction of latch hooks 2, and the guiding along with latch hook 2 rotates, realizes the separated of tractor truck and superimposed trailer.
