[0001] The present invention relates to the technical field of a locking assembly, a side guard plate device and a through passage, and in particular to a locking assembly, a side guard plate device and a through passage. Background Art

[0002] The through-tunnel is a key connecting component of rail vehicles. Its main function is to connect two adjacent carriages in a flexible manner so that rail vehicles can pass through curved roads. The side guard plates in the through-tunnel are the main components. When installed and connected, the side guard plates are detachably connected to the vehicle body through connecting profiles. Specifically, the blind spot locking device disclosed in Patent No.: CN214267604U and the side guard plate locking system including the blind spot locking device are specifically adjusted from the top of the side guard plate through the handle and the support column to adjust the position of the lock plate in the profile relative to the lock hook, so that the lock mouth in the lock plate can move relative to the lock hook. When this product is used, the gap between the top of the side guard plate and the top plate is too small, and the gap for the operator to extend his arm is not enough. It is necessary to use other external forces to expand the gap between the side guard plate and the top plate, which leads to many inconveniences in the unmarshalling process. Summary of the invention

[0025] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements with the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and are not to be construed as limitations of the present invention. On the contrary, embodiments of the present invention include all changes, modifications and equivalents that fall within the spirit and connotation of the appended claims.

[0026] like Figure 1 As shown, the present invention provides a through passage, including a folding roof device 10, a top plate device 20, a tread plate device 30 and a side guard plate device 40, the top plate device 20 is installed on the top of the side guard plate device 40, the tread plate device 30 is installed on the bottom of the side guard plate device 40, there are two side guard plate devices 40, and the two side guard plate devices 40 are symmetrically arranged between the top plate device 20 and the tread plate device 30. Through the above arrangement, the top plate device 20, the side guard plate device 40 and the tread plate device 30 constitute a hollow passage structure that is approximately a square frame. The folding roof device 10 is arranged around the outside of the hollow passage structure to form protection for the hollow passage structure. The folding roof device 10, the top plate device 20, the tread plate device 30 and the side guard plate device 40 can all be detachably connected to the vehicle end, and the folding roof device 10, the top plate device 20, the tread plate device 30 and the side guard plate device 40 are all retractable structures, and with the help of their own retractable characteristics, the rail vehicle can adapt to curved roads.

[0027] like Figure 1 and Figure 2 As shown, the side guard plate device 40 includes a side guard plate 410 , a profile component 420 connecting the side guard plate 410 and the vehicle end, and a locking component 430 installed in the profile component 420 .

[0028] like Figure 2 and Figure 3As shown, a profile area 411 is provided on the inner surface of the side guard plate 410, and a profile assembly 420 includes a plate connection profile 421 installed in the profile area 411, a rotating profile 422 corresponding to the plate connection profile 421, and a positioning profile 423 provided on the vehicle body. The plate connection profile 421 is provided along the vertical direction of the side guard plate 410, the plate connection profile 421 and the rotating profile 422 are embedded and connected, the side edge of the rotating profile 422 is rotatably connected to the positioning profile 423, the positioning profile 423 is fixed to the vehicle end, and both ends of the side guard plate 410 are hoisted and connected to the vehicle end through the profile assembly 420.

[0029] like Figures 4 to 8 As shown, the locking assembly 430 includes a locking hook 431 fixedly mounted on the plate connecting profile 421 , a locking plate 432 slidably inserted into the rotating profile 422 , and a rotating block 433 mounted on the bottom of the locking plate 432 .

[0030] like Figure 3 As shown, the lock plate 432 and the rotating profile 422 are both provided with lock holes, and the lock hook 431 is arranged corresponding to the lock hole. The lock hole is opened along the length direction of the rotating profile 422, and the opening area of ​​the lock hole is larger than the cross-sectional area of ​​the lock hook 431. That is, when the lock hook 431 is in the lock hole, the side guard plate 410 can move relative to the lock hook 431 until the lock hook 431 can be separated from the lock hole. Figure 4 As shown, the locking plate 432 is roughly in the shape of a long plate corresponding to the inner cavity of the rotating profile 422. The bottom end of the locking plate 432 along the gravity direction abuts against the rotating block 433. The rotation of the rotating block 433 can drive the locking plate 432 to move up and down in the rotating profile 422, and then cooperate with the locking hook 431 for plugging and unplugging.

[0031] like Figure 4 , Figure 7 and Figure 8 As shown, the rotating block 433 is arranged below the rotating profile 422, and the rotating block 433 is rotatably installed at the bottom of the rotating profile 422. The rotating block 433 is a disc-shaped structure. A rotating groove 434 is provided on the surface of the rotating block 433. The rotating groove 434 is spirally arranged on the rotating block 433, and the end of the locking plate 432 is in contact with the groove bottom of the rotating groove 434. The spiral center of the rotating groove 434 is the rotation center of the rotating block 433 relative to the rotating profile 422. When the rotating block 433 rotates relative to the rotating profile 422, the rotating block 433 rotates relative to the locking plate 432, and the rotating groove 434 rotates relative to the locking plate 432. Due to the spiral characteristics of the rotating groove 434, the height of the contact position between the locking plate 432 and the rotating block 433 changes in the direction of gravity. As the contact position of the locking plate 432 changes, the position of the locking hole relative to the locking hook 431 changes.

[0032] like Figures 6 to 8 As shown, a mounting seat 424 is provided in the rotating profile 422, and a rotating block 433 is rotatably connected to the mounting seat 424. A connecting shaft 435 is convexly provided on the rotating block 433, and the connecting shaft 435 is rotatably inserted into the mounting seat 424. A screw is inserted in the end of the connecting shaft 435 in the rotating profile 422, and a gasket is sleeved on the screw. The gasket is attached to the top of the mounting seat 424 under the pressure of the screw. Under the restriction of the screw, the connecting shaft 435 is rotatably accommodated in the mounting seat 424, thereby completing the rotation connection between the rotating block 433 and the mounting seat 424. A driving member 451 is also provided on the rotating block 433, and the driving member 451 can be operated to rotate relative to the positioning profile 423.

[0033] Preferably, Figure 2 , Figure 4 as well as Figure 5 As shown, the driving member 451 is a protrusion 452 on the rotating block 433, the protrusion 452 and the rotating groove 434 are on both sides of the rotating block 433, the protrusion 452 is a multi-prism structure, and the rotating block 433 can be driven to rotate by twisting the protrusion 452. When in use, the control sleeve is inserted below the protrusion 452 through the space at the bottom of the bellows, and the inner hole of the control sleeve corresponds to the shape of the protrusion 451. After the control sleeve is sleeved on the outer surface of the protrusion 451, the driving member 451 and the rotating block 433 can be driven to rotate relative to the mounting seat 424 by twisting the control sleeve to rotate, thereby pushing the locking plate 432 to move.

[0034] Preferably, this embodiment is different from the above embodiment in that Figure 6 As shown, the driving member 451 in this embodiment is a lever block 453 on the rotating block 433. The lever block 453 is arranged along the radial protrusion of the rotating block 433. The edge of the lever block 453 is arranged close to the bottom of the side guard plate 410. The operator can push the lever block 453 to rotate around the mounting seat 424 from the bottom of the side guard plate 410.

[0035] Preferably, Figure 4 , Figure 6 as well as Figure 7 As shown, a stopper 425 is protruding from the bottom of the rotating profile 422 and the bottom of the mounting seat 424, and the edge of the rotating block 433 is raised along the angle of the rotating groove 434, so that after the rotating block 433 rotates around the mounting seat 424, the edge of the rotating block 433 can abut against the stopper 425, that is, the rotation angle of the rotating block 433 relative to the mounting seat 424 corresponds to the layout angle of the rotating groove 434.

[0036] When the above-mentioned through passage is being disassembled or connected, especially when the side guard plate 410 is being disassembled and assembled, the rod-shaped tooling for disassembly and connection is inserted through the gap between the bottom of the side guard plate 410 and the stepping plate device 30, and the rotating block 433 is rotated by the tooling. The rotating groove 434 on the rotating block 433 rotates synchronously, and the rotating groove 434 moves relative to the locking plate 432. The bottom of the locking plate 432 climbs along the rotating groove 434 in the rotating profile 422, and the locking hole on the locking plate 432 is finally aligned with the locking hole on the rotating profile 422, and the locking hook 431 can be pulled out from the locking hole, thereby completing the disassembly of the side guard plate 410 from the vehicle body. On the contrary, the tooling and driving member 451 are also used to manipulate the rotating block 433 to rotate, and the locking plate 431 falls along the rotating slope 434, pushing the locking hook 431 on the side guard plate 410 toward the locking hole. Under the push of the locking hook 431, the locking plate 431 slides in the rotating profile 422 until the locking hook 431 is accommodated in the rotating profile 422, and the locking plate 431 slides back in the rotating profile 422 until the hole wall of the locking hole overlaps the inner bend of the locking hook 431, thereby completing the connection of the side guard plate 410.

[0037] Based on the above ideal embodiments of the present invention, the relevant staff can make various changes and modifications without departing from the technical concept of the present invention through the above description. The technical scope of the present invention is not limited to the contents of the specification, and its technical scope must be determined according to the scope of the claims.
