Figure 1-4 The locomotive belt sealing hose handshake includes a main body 1, a plug 2, a movable shaft 3, a handle 4, a guide protrusion 5, a sleeve 6 and a reset spring 7. The main body 1 is provided with a card slot 122 adapted to the hose connector. The hose connector is a common structure and is not described in detail in this embodiment. The interior of the main body 1 is provided with a cavity 100 and openings are provided at both ends. The movable shaft 3 slides along the central axis and is rotatably connected in the cavity 100. The plug 2 is provided with a protrusion 21 in the middle of the outer side surface near the card slot 122. The plug 2 is rotatably connected to one end of the movable shaft 3. The handle 4 is fixed to the other end of the movable shaft 3. An annular baffle is provided on the inner circumferential wall of the cavity 100. 121, the movable shaft 3 passes through the sleeve 6 and the return spring 7, the return spring 7 is sandwiched between the plug 2 and the annular baffle 121, the elastic force of the return spring 7 drives the plug 2 to always have a tendency to move outward, the movable shaft 3 is movably connected with the sleeve 6, the sleeve 6 is fixed in the cavity 100 of the main body 1, the guide protrusion 5 is fixed on the movable shaft 3, the sleeve 6 is provided with an arc-shaped oblique guide groove 61 and a linear groove 62 that are connected to each other, the arc-shaped oblique guide groove 61 is arranged obliquely along the circumference of the sleeve 6 and has a first limit position 611 and a second limit position 612 at both ends, and the linear groove 62 is arranged along the axial direction of the sleeve 6 and is connected to the second limit position 612;
[0043] When the handle 4 is turned, the guide protrusion 5 slides in the arc-shaped inclined guide groove 61. When the guide protrusion 5 slides to the first limit position 611, the plug 2 is pulled back to the sealing position, that is, the outer side surface of the plug 2 close to the slot 122 is located outside the cavity 100 and the distance between the plug 2 and the outer end surface of the main body 1 is between 1-2 mm. When the guide protrusion 5 slides to the second limit position 612, the plug 2 is pulled back to the hanging position, that is, the outer side surface of the plug 2 close to the slot 122 is flush with the outer end surface of the main body 1. At this time, the protrusion 21 is still located outside the cavity 100;
[0044] When the handle 4 is pulled outward linearly, the guide protrusion 5 slides in the linear groove 62 , and the plug 2 is pulled back to the unlocking position, that is, the protrusion 21 is completely hidden in the cavity 100 to ensure that the hose connector can be disengaged from the slot 122 .
[0045] In order to ensure better power conversion between the guide protrusion 5 and the sleeve 6, the rotational motion of the movable shaft 3 is converted into a linear contraction motion of the plug 2, and interference between the guide protrusion 5 and other components in the cavity 100 is avoided during the power conversion process. The guide protrusion 5 is a hexagon socket cylindrical head screw threadedly assembled on the movable shaft 3, and the width of the arc-shaped inclined guide groove 61 and the straight groove 62 is adapted to the cylindrical head diameter of the guide protrusion 5, and the depth of the arc-shaped inclined guide groove 61 and the straight groove 62 is greater than the cylindrical head length of the guide protrusion 5.
[0046] In order to facilitate the quick installation and fixation of the sleeve 6 in the cavity 100 of the main body 1, the main body 1 includes a cylindrical portion 11 and a clamping portion 12 with a slot 122.

Combined with the split design of the main body 1 and the pin connection method, not only can a firm connection between the sleeve 6 and the main body 1 be achieved, but also later disassembly, maintenance and reassembly are convenient.
[0047] In order to remind the operator to quickly know whether the current handshake is in the sealing position or the hanging work, an indicator arrow 400 is provided on the outer surface of the handle 4, and a sealing marking line 112 and a hanging marking line 113 are provided on the outer peripheral wall of the main body 1. When the indicator arrow 400 points to the sealing marking line 112, the plug 2 is pulled back to the sealing position, and when the indicator arrow 400 points to the hanging marking line 113, the plug 2 is pulled back to the hanging position. When the handle 4 is rotated 90 degrees, the guide protrusion 5 slides from the first limit position 611 of the arc-shaped inclined guide groove 61 to the second limit position 612. The above structural design is convenient for the staff to observe, use and operate.
[0048] When switching states, the plug 2 will slide back and forth in the cavity 100. In order to prevent relative rotation between the plug 2 and the main body 1 during the above process, a plurality of spaced limit bars 123 are provided on the inner circumferential wall of the cavity 100. The limit bars 123 are parallel to the movable axis 3. A plurality of limit grooves 22 are provided on the circumferential side of the plug 2. The limit bars 123 and the limit grooves 22 are arranged one by one correspondingly and are used to prevent the plug 2 from rotating in the cavity 100.
[0049] In this embodiment, a rotation connection groove 23 is provided on the inner side of the plug 2 away from the protrusion 21, and a connection plate 33 is vertically connected to the end of the movable shaft 3 close to the plug 2. The connection plate 33 rotates freely in the rotation connection groove 23 and is limited and fixed by the clamping spring 8. The connection structure designed above is easy to assemble and has a stable connection. It can not only realize a firm connection between the rotating shaft and the plug 2, but also realize relative rotation between the rotating shaft and the plug 2.
[0050] In order to facilitate the rapid installation and removal of the hose connector in the slot 122 of the main body 1, the protrusion 21 is a disc structure, and a guide slope 211 is provided on the end surface of the protrusion 21 away from the slot 122. The guide slope 211 is used to assist the hose connector to be quickly inserted into the slot 122.
[0051] In order to prevent relative rotation between the movable shaft 3 and the handle 4 , a square end 31 is provided at the end of the movable shaft 3 close to the handle 4 , and a square groove 41 for the square end 31 to be inserted into is provided in the handle 4 .

The connection structure designed above is easy to assemble and has a stable connection. It can not only achieve a firm connection between the rotating shaft and the handle 4, but also achieve the effect of hiding the gasket 42 and the locking bolt 43. The design of the cover 44 is conducive to preventing external foreign matter from clogging the installation cavity.
[0053] The beneficial technical effects of the locomotive belt sealing hose handshake of the embodiment of the present application are roughly as follows:
[0054] By utilizing the cam guiding principle, the guide protrusion 5 and the shaft sleeve 6 are used in combination. Combined with the premise that the plug 2 is rotatably connected to the movable shaft 3, the rotational movement of the movable shaft 3 can be converted into a linear contraction movement of the plug 2. When the hose connector of the locomotive only needs to be fixed on the handshake, the guide protrusion 5 is in a normal state, that is, on the second limit position 612. At this time, the handshake can realize the basic suspension function; when the locomotive needs to be tested, the handle 4 is rotated, and the guide protrusion 5 slides from the first limit position 611 to the second limit position 612, that is, the plug 2 protrudes a little, so that the rubber part of the plug 2 and the hose connector reaches a sealed state. At this time, it can ensure that there is no need to repeatedly disassemble the tooling and the handshake during the test, and prevent the machine damage accident caused by the leakage of the corner plug door. The end of the hose connector away from the handshake is connected to the main and branch air ducts of the corner plug door. When the corner plug door is closed, the sealing gasket leaks air, which easily causes the wind pressure to drop. The vehicle has to stop and wait for rescue. In recent years, the machine damage accidents of locomotives during driving due to the leakage of the corner plug door sealing gasket are common and extremely harmful.
[0055] Different from the state switching components of common hose interlocking sealing fixing devices, the complex multi-rod spring structure is simplified into a guide protrusion 5, a sleeve 6 and a handle 4. The handle 4, which can only be started by gripping and turning, is not easy to be touched by mistake. At the same time, the core components, the guide protrusion 5 and the sleeve 6, are both located in the cavity 100 of the main body 1, and are less likely to be damaged by impact. The overall structure is simpler and more compact, suitable for use in small installation locations, and more convenient to operate.
[0056] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the application should be included in the protection scope of the present application.
