By following description also in conjunction with the accompanying drawings, it is more clear that the utility model will become, and these accompanying drawings are used to explain embodiment of the present utility model.
Description of drawings
Fig. 1 is the front view of the utility model saddle traction seat.
Upward view when Fig. 2 is in traction state for the utility model saddle traction seat.
Fig. 3 is that the utility model saddle traction seat is in the upward view when taking off the extension state.
The specific embodiment
With reference now to accompanying drawing, describe embodiment of the present utility model, the similar elements label is represented similar elements in the accompanying drawing.
As Figure 1-3, shown the front side of shaking hands to be installed in one side, wheel tractor right side and being positioned at traction seat.The saddle traction seat of present embodiment comprises housing 10, pair of brackets 11, handle 12, trip lever 13, wedge 14, latch hook 15, latch hook extension spring 16, handle extension spring 17, pintle hook lock 18, adjusts screw rod 19 and open end cap 20.Described housing 10 middle parts offer towing pin inlet 101, and described open end cap 20 is installed in described towing pin 101 places that enter the mouth.A pair of described support 11 symmetries are fixed on the bottom surface of described housing 10.
Offer pilot hole (not shown) near described towing pin 101 places that enter the mouth along the horizontal cross direction of described housing 10 on the described housing 10, described wedge 14 is arranged in the described pilot hole and along described pilot hole and slides.The installation end of described latch hook 15 is installed in the left side of described towing pin inlet 101 by lock hook pin 151.Described latch hook 15 is positioned at the top of described wedge 14 and the free end of described latch hook 15 is connected with described wedge 14 conflicts, is used for and described towing pin inlet 101 composition closed circular, to pin towing pin.Particularly, the left end of the side that described wedge 14 and described latch hook 15 are relative is provided with arc notch 141, and the free end of described latch hook 15 is formed with the projection 152 that matches with described arc notch 141.Understandably, arcuate structure can make between described wedge 14 and the described latch hook 15 and realize seamlessly transitting, thereby makes the process that connects the extension and take off extension more smooth and easy.
The two ends of described latch hook extension spring 16 are articulated in respectively on described housing 10 and the described latch hook 15.Described trip lever 13 is installed on described wedge 14 and the described housing 10 by two pivots 131 and the front side that is positioned at described latch hook 15 promptly is positioned at the front side of described housing 10.Described handle 12 is articulated on the described trip lever 13 and is positioned at the front side of described housing 10.The two ends of described handle extension spring 17 are articulated in respectively on described handle 12 and the described housing 10.Understandably, described handle extension spring 17 can make described handle 12 be in the wedging position, and then makes described wedge 14 be in the wedging state, to prevent that in the process of moving described wedge 14 slippages cause described latch hook 15 unexpected unhook.
Described pintle hook lock 18 is positioned at the same side with described handle 12 and is articulated on the side of described housing 10, and described handle 12 and described pintle hook lock 18 relative sides are provided with opening, and described pintle hook lock 18 is fastened in the described opening separably.Described adjustment screw rod 19 is threaded on the described housing 10 and is relative with the top of described wedge 14.Understandably, in the process of moving, described pintle hook lock 18 is to be buckled in the opening of described handle 12, and described handle 12 can't move along the horizontal cross direction of described housing 10, thereby can avoid the accident of described latch hook 15 to break off relations, and described adjustment screw rod 19 can limit the shift motion of described wedge 14.
Describe the working process of the utility model saddle traction seat in detail below in conjunction with Fig. 1-3.
When the saddle traction seat is in when connecing the extension state, towing pin inlet 101 is in open mode, the wheel tractor reversing, towing pin bump latch hook 15 on the superimposed trailer, wedge 14 is backed down in the effect that makes latch hook 15 overcome latch hook extension spring 16, does left-hand revolution then, thereby towing pin is pinned.Simultaneously, handle extension spring 17 pulling handles 12 also promote wedge 14 by trip lever 13, make wedge 14 wedging latch hooks 15.Rotate pintle hook lock 18 then, pintle hook lock 18 is fastened in the opening 121 of handle 12, thus fixing handle 12, and then finish the extension process that connects.
When the saddle traction seat was in traction state, the towing pin of superimposed trailer was locked in the closed circular of being made up of latch hook 15 and open end cap 20.At this moment, wedge 14 wedging latch hooks 15 make it and can not rotate around lock hook pin 151.
When the saddle traction seat is in when taking off the extension state, chaufeur rotates 90 ° with pintle hook lock 18, will shake hands 12 to be pulled outwardly, and leaves latch hook 15 by trip lever 13 drive wedges 14.Latch hook 15 is clickwise under the effect of latch hook extension spring 16, withstands latch hook 15 up to wedge 14 latch hook 15 is not rotated, thereby open towing pin inlet 101, and this moment, wheel tractor can make traction seat leave towing pin to overtake, realized taking off extension.
As from the foregoing, because the handle 12 of the utility model saddle traction seat can be installed in the front side or the rear side of housing 10, thereby, can be according to the different installation sites that handle 12 is set of rear wheel cover on the vehicle of wheel tractor and the wheel tractor, and then increased the user to the range of choice on chassis or reduced repacking work capacity to the chassis.
It should be noted that the handle of the utility model saddle traction seat can also be installed in the rear side of traction seat, its connection mode and structure are similar to the aforementioned embodiment, repeat no more herein.
