Abstract
The invention discloses a kind of tight lock couplers, it includes tension spring, coupler body, hook lock assembly and uncoupling cylinder, hook lock assembly is connected with tension spring, the projection to hook lock assembly is rectified in the telescopic shaft work of uncoupling cylinder, the present invention is connected with central shaft by flat key, is installed in coupler body, the machinery formed even suspension mechanism, lining is installed at connecting pin, effectively realizes self-lubricating and avoid the formation of dry friction reduction even extension performance.
Description
Technical field
The present invention relates to a kind of tight lock couplers.
Background technology
Tight lock couplers is divided into full-automatic hitch, semi-automatic hitch and semi-permanent car coupler according to the difference of function.Automatically
Hitch can realize circuit, gas circuit, automatically connecting of mechanical part hang and decompose；Semi-automatic hitch can realize gas circuit, mechanical part
From being dynamically connected, but needing manual uncoupling, connection and the decomposition of electricity also need manual operation；The electricity of semi-permanent car coupler, gas, the connection of machinery
Connect and decomposition is required for manual operation.
The shibata shiki coupler of the mainly Japan that the tight lock couplers of China is copied, manufacturer has weir, South China Che Qi villa
Rolling stock technical study company limited of institute and the company limited of cubic vehicle research institute of China's north car.Its product has structure letter
The advantage such as single, easy to maintenance, but there is also the shortcoming that automaticity is low, Life Cycle Cost is high, it is impossible to meet railway long
The needs of phase development.
Summary of the invention
It is an object of the invention to provide a kind of tight lock couplers, with the problem solving to propose in above-mentioned background technology.
For achieving the above object, the present invention provides following technical scheme: a kind of tight lock couplers, it include tension spring,
Coupler body, hook lock assembly and uncoupling cylinder, hook lock assembly is connected with tension spring, and the telescopic shaft work of uncoupling cylinder is rectified hook lock
The projection of assembly.
Preferably, described hook lock assembly includes coupler knuckle plate, connecting pin and connecting rod, and coupler knuckle plate is provided with pin-and-hole, pin-and-hole
Corresponding with connecting rod and connecting pin, coupler knuckle plate is provided with central shaft hole, is provided with rectangular channel in central shaft hole, is provided with flat in rectangular channel
Key.
Preferably, described connecting pin is provided with lining, and connecting pin bottom is provided with back-up ring.
Compared with prior art, the invention has the beneficial effects as follows: the present invention is connected with central shaft by flat key, be installed on
In coupler body, the machinery formed even suspension mechanism, SF-1 lining is installed at connecting pin, effectively realizes self-lubricating and avoid the formation of
Dry friction reduces even hangs performance.
Accompanying drawing explanation
Fig. 1 is present configuration schematic diagram.
Fig. 2 is exploded view at 3 in Fig. 1.
In figure: 1 tension spring, 2 coupler bodies, 3 hook lock assemblies, 4,5 uncoupling cylinders, 6 connecting pins, 7 linings, 8 back-up rings, 9 connect
Bar, 10 flat keys, 11 coupler knuckle plates, 12 pin-and-holes, 13 rectangular channels.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Describe, it is clear that described embodiment is only a part of embodiment of the present invention rather than whole embodiments wholely.Based on
Embodiment in the present invention, it is every other that those of ordinary skill in the art are obtained under not making creative work premise
Embodiment, broadly falls into the scope of protection of the invention.
Referring to Fig. 1, the present invention provides a kind of technical scheme: a kind of tight lock couplers includes tension spring 1, coupler body 2, hook
Lock set 3 and uncoupling cylinder 5, hook lock assembly 3 is connected 1 with tension spring, and the telescopic shaft work of uncoupling cylinder 5 is rectified hook lock group
The projection of part 3.
Shown in Fig. 2, hook lock assembly 3 includes coupler knuckle plate 11, connecting pin 6 and connecting rod 9, and coupler knuckle plate 11 is provided with pin-and-hole 12,
Pin-and-hole 12 is corresponding with connecting rod 9 and connecting pin 6, and coupler knuckle plate 11 is provided with kingpin hole 4, is provided with rectangular channel 13 in kingpin hole 4,
Flat key 10 it is provided with in rectangular channel 13.
Described connecting pin 6 is provided with lining 7, and connecting pin 6 bottom is provided with back-up ring 8.
Hook lock assembly 3 is the main stressed member of hitch, bears pull strength, when hitch is even hung, with another hook lock device
Forming stable parallelogram sturcutre, hook lock assembly 3 is connected with central shaft by flat key 10, is installed in coupler body, is formed
The machinery completed even suspension mechanism.The lining 7 of design and installation self-lubricating at connecting pin, effectively realizes self-lubricating and avoids the formation of unlubricated friction
Wipe to reduce and even hang performance.
Although an embodiment of the present invention has been shown and described, for the ordinary skill in the art, permissible
Understand and these embodiments can be carried out multiple change without departing from the principles and spirit of the present invention, revise, replace
And modification, the scope of the present invention be defined by the appended.
