Specific embodiment

In the following, the embodiment of the present invention is described with reference to the drawings, but should not be limited to the following examples:

Shown in Figure 1, a kind of collapsible hand handle machinery alleviation device, structure is: including for alleviating and restoring to grasp The hand handle 1 of work, hand handle 1 are mounted on 14 upper end of shaft by hex nut 2, spring washer 3, plain washer 4；Shaft 14 is by upper lower nut 6, plain washer 13 and 5 flexible installing of O-ring seals are in fixing sleeve 9, and shaft 14 can rotate in fixing sleeve 9, and fixing sleeve 9 is by vehicle Upper clamp nut 7, O-ring seals 8 and vehicle lower compression nut 12, sealing plain washer 11 are fixed on 10 tapping of vehicle floor, Gu Surely set 9 and shaft 14 run through about 10 floor；14 lower end of shaft is connect by elastic cylindrical pin 15 with Hooks coupling universal coupling, universal joint shaft Device is by two universal joints 16 and hexagon ring set 17 and hexagonal rod 18 with being combined into, and two universal joints 16 are respectively by elastic cylindrical pin 15 Hexagon ring set 17 and hexagonal rod 18 are connected, hexagon ring set 17 and the cooperation of hexagonal rod 18 are for transmitting torque, hexagon ring set 17 and six It can axial stretching between angle rod 18；It is connect by elastic cylindrical pin 15 with 19 top of transition coupling head in Hooks coupling universal coupling lower end, 19 lower end of transition coupling head is connect with graduated release valve 20 on braking air-supply pipeline, and hand handle is also equipped on graduated release valve 20 may be implemented in vehicle Under carry out alleviate and recovery operation.

It is shown in Figure 2, piston rod 25 by connecting pin 29 sell riveting on handle set 30, spring 26 by soket head cap screw 22, Spring washer 23 and compress gasket 24 are fitted between piston rod 25 and bushing 28, by detent steel between bushing 28 and taper knob 21 27 axial restraint of wire ring, can be along axial circle rotation.When normal condition does not operate, handle is in plumbness, utilizes spring force By the lock of piston rod 25 in handle set axial groove, need to be lifted up taper knob when needing to operate makes piston rod 25 be detached from handle The backward horizontal direction switching of seat is locked piston rod 25 on handle set sagittal plane using spring force when pulling to horizontal direction, Air damping alleviation and recovery operation can be carried out as needed；After end of operation, taper knob, which is lifted up, takes off piston rod 25 From to vertical direction switching, when pulling to vertical direction, piston rod 25 is locked in handle set axial direction using spring force after handle set In slot.

When air damping being needed to alleviate and restore, headwall inspection door can be onboard opened, collapsible hand handle 1 is pulled to level Position and rotary handle 1, hand handle 1 rotate simultaneously with shaft 14 and upper cardan, and upper cardan passes through hexagon ring set 17 and hexagonal Stick 18 drives lower cardan to rotate synchronously, and the rotation of 20 valve rod of graduated release valve, real cars on hand are driven via transition coupling head 19 Upper to carry out alleviation and recovery operation by rotary handle, structure is simple and direct effectively, can quickly carry out air damping alleviation and recovery, no It will affect the time response of air damping；Also can under vehicle by rotation graduated release valve 20 on the other hand come realize alleviate and it is extensive Multiple operation；Collapsible hand handle 1 is pulled to upright position after the completion of operation, shuts headwall inspection door.

The universal joint 16 is the parts for realizing the transmitting of varied angle power, for needing to change the position of transmission axis direction It sets, the present invention uses double Hooke's joint, is exactly that both ends of the drive shaft respectively has a universal joint, effect is the angle for making both ends of the drive shaft It is equal, to guarantee that output shaft and the instantaneous angular velocity of input shaft are equal always.The transmission shaft that the present invention uses to be split type, by Hexagon ring set 17 and hexagonal rod 18 are with being combined into, and hexagonal rod 18 can cover the movement of 17 inner axis in hexagon ring, and formation can transmit torsion Square also retractable.Braking air-supply pipeline and 10 height L deviation ± X of vehicle floor caused by can solving in manufacturing process are installed It is braked under problem, 10 position of opening of floor caused by can also solving in manufacturing process and vehicle on air-supply pipeline before 20 position of graduated release valve Arranged in dislocation problem caused by the relative position dimensional discrepancy Y of left and right afterwards.

Although having been shown that detailed embodiment of the invention above, it is therefore apparent that those skilled in the art without prejudice to Under the premise of the present invention, part modifications and changes can be carried out；The content referred in description above and attached drawing is only used as illustrative Illustration, be not intended as limitation of the present invention, with above-mentioned technical characteristic collapsible hand handle machinery alleviate device, each fall within The scope of the present invention.
