TECHNICAL FIELD
[0001] The utility model relates to a railway vehicle, concretely relates to a locking structure of a railway vehicle folding shed inner wind screen. BACKGROUND
[0002] The wind screen is arranged between the car bodies of two adjacent railway vehicles, and the inner wind screen is generally a folding shed wind screen. The folding shed wind screen is formed by pressing an end frame and a shed cloth, and the inner and outer folding sheds are connected by the end frame. One end surface of the end frame is fixedly connected with the inner and outer folding sheds, and the other end surface is fixedly connected with the car body. When the folding shed inner wind screen is installed, the installation of the folding shed inner wind screen is completed by connecting the end frame with the transition plate installed on the car body. When the state of the external components of the car end inner wind screen, the state of the inner wind screen or other maintenance operations need to be checked, the wind screen needs to be disassembled, the inner wind screen needs to be disassembled and the maintenance operation needs to be completed, and then the inner wind screen needs to be reconnected and restored.
[0003] The existing disassembly and connection functions are basically realized by a locking mechanism. The existing locking mechanism is arranged outside the end frame and must be arranged at a reasonable position to avoid interference with the components on the transition plate. If the installation position or structure of the components on the transition plate changes, the position or structure of the locking mechanism also needs to be changed accordingly, so that the compatibility of the existing locking mechanism is poor, and the design and development cycle of the series is long. SUMMARY
[0004] To solve the above problems, the utility model provides a railway vehicle folding shed inner wind screen locking structure which is simple in structure, convenient and practical, safe and reliable in design, and can reduce the complex cooperation between other components.
[0005] The utility model discloses a railway vehicle folding shed inner wind screen locking structure, including end frame and the lock rod, pressing plate, lock rod positioning seat, compression spring, spring guide column that set up in the end frame, transition plate and the lock hook that are fixedly connected with transition plate, lock rod positioning seat is fixed between the inner wall of end frame and lock rod, lock rod positioning seat is equipped with the recess along the length direction, lock rod is slidably equipped in the recess of lock rod positioning seat, lock rod is equipped with the lock mouth that cooperates with lock hook, spring guide column is located at one side of lock rod, and spring guide column is fixedly connected with end frame, pressing plate is fixedly connected with lock rod, and pressing plate is slidably covered on spring guide column, spring guide column bottom is equipped with compression spring support platform, and compression spring is covered on spring guide column and is equipped between pressing plate and compression spring support platform.
[0006] Further, the two ends of the lock rod positioning seat are respectively provided with an upper clamping plate assembly and a lower clamping plate assembly. The upper clamping plate assembly and the lower clamping plate assembly are respectively fixedly connected with the end frame. The lock rod positioning seat is positioned and fixed by the upper clamping plate assembly and the lower clamping plate assembly, so as to avoid machining a threaded hole on the lock rod positioning seat. The lock rod positioning seat can also close the opening of the end frame, thereby increasing the strength of the locked end frame.
[0007] Further, the upper clamping plate assembly and the lower clamping plate assembly each comprise an outer side plate arranged at the outer side of the outer wall of the end frame and an inner side plate arranged at the inner side of the outer wall of the end frame, and the inner side plate is provided with a threaded hole, and the outer side plate, the outer wall of the end frame and the inner side plate are sequentially fixedly connected by screws.
[0008] Further, the pressing plate fixedly connected with the lock rod is located below the inner side plate of the lower clamping plate assembly, and the position of the inner side plate in contact with the pressing plate is adapted to the position where the lock hole is separated from the lock hook. When the lock rod moves upward, the lock hole is separated from the lock hook, the locking mechanism is in an open state, and the open position of the lock rod is just in the state where the pressing plate interferes with the inner side plate. At this time, it is explicitly informed to the operator that the locking mechanism has completed the opening operation, so as to avoid the disengagement of the pressing plate from the spring guide column.
[0009] Further, the material of the lock rod positioning seat is nylon.
[0010] Further, the lock rod positioning seat is a plurality of lock rod positioning seats, which are arranged at intervals along the length direction of the lock rod.
[0011] The locking structure of the rail vehicle folding shed inner wind screen comprises a lock rod in an end frame, the lock rod moves up and down in the end frame of the folding shed inner wind screen, and the lock hook on the transition plate on the vehicle body is locked or separated, so that the connection between the entire folding shed assembly and the transition plate is realized. When the lock rod moves upward, the lock hole on the lock rod corresponds to the lock hook on the transition plate, and the separation is formed, so that the opening function is realized. When the lock rod moves downward, the lock hole on the lock rod moves downward, the lock rod is locked with the lock hook on the transition plate, and the locking function is realized. When the lock rod moves downward, the pressing plate fixed on the lock rod moves downward, the pressing plate presses the compression spring to move downward along the spring guide column, and the compression spring is compressed. When the lock rod moves upward, the pressing plate fixed on the lock rod moves upward, the compression spring moves upward, and the compression spring is still in a compressed state at the limit point of the upward movement of the lock rod, and provides elastic force upward. When the lock rod is opened, due to its own gravity, there is a downward movement trend, and the compression spring is used to support the gravity of the lock rod, so that the opened lock rod can be fixed at a determined position and cannot move downward, so that the opening state of the lock rod is always maintained, and the lock rod is prevented from falling into the closed state by itself. The spring guide column plays a guiding and supporting role on the compression spring, so that the deformation of the spring compression process is controllable. In the opening state, the pressing plate interferes with the lower limit plate, so that the pressing plate is prevented from moving upward excessively and being separated from the spring guide column, and the opening operation is conveyed to the unlocking personnel. The spring guide column and the compression spring are arranged in the cavity of the end frame profile, so that the assembly relationship with other parts of the transition plate is completely avoided, the design and assembly interference check is reduced, and the repeated modification design and product modification caused by the change of the transition plate parts are reduced.
[0012] The locking structure of the rail vehicle folding shed inner wind shield has simple structure, convenient dismounting, high efficiency, labor saving, high safety, low maintenance cost, safe and reliable design, good compatibility, reduced complex cooperation with other components and shortened design and development period of serialized products.

DETAILED DESCRIPTION
[0021] The locking structure of the rail vehicle folding shed inner wind shield will be described in detail below. Figures 1 to 6
[0022] The locking structure of the rail vehicle folding shed inner wind shield has simple structure, convenient dismounting, high efficiency, labor saving, high safety, low maintenance cost, safe and reliable design, good compatibility, reduced complex cooperation with other components and shortened design and development period of serialized products.
[0023] As Figure 1 The locking structure of the inner windshield of the rail vehicle folding shed is arranged on an end frame 1 fixedly connected with the inner windshield and a transition plate 7 fixedly connected with the vehicle body.
[0024] As shown in Figure 2 , the locking hook 6 is arranged on the surface of the transition plate 7 close to the end frame 1 and is fixedly connected with the transition plate 7; the end frame 1 is internally provided with a lock rod 2 capable of moving up and down, and the lock rod 2 is provided with a lock opening matched with the locking hook 6. When the lock rod 2 moves downward to make the lock opening correspond to the position of the locking hook 6, the lock rod 2 and the locking hook 6 do not interfere with each other, and the state is an open state; when the lock rod 2 moves upward to make the lock opening away from the locking hook 6, the lock rod 2 and the locking hook 6 interfere with each other, and the state is a locking state.
[0025] As shown in Figures 3 to 6 , the end frame 1 is internally provided with the lock rod 2, a pressing plate 3, a compression spring 4, a spring guide column 5 and a lock rod positioning seat 10. The lock rod positioning seat 2 is made of nylon and is fixed between the inner wall of the end frame 1 and the lock rod 2, the lock rod positioning seat 10 is provided with a through groove along the length direction, and the lock rod 2 can move along the groove in the groove of the lock rod positioning seat 10. The lock rod positioning seat 10 is a plurality of lock rod positioning seats 10 and is arranged at intervals along the length direction of the lock rod 2.
[0026] As shown in Figure 2 and Figure 3 , the lock rod 2 is located on one side of the spring guide column 5, the spring guide column 5 is fixedly connected with the end frame 1; the pressing plate 3 is fixedly connected with the lock rod 2, and the pressing plate 3 is sleeved on the spring guide column 5 and can move along the spring guide column 5.
[0027] The bottom end of the spring guide column 5 is provided with a compression spring support table 12, the compression spring 4 is sleeved on the spring guide column 5 and is arranged between the pressing plate 3 and the compression spring support table 12.
[0028] As shown in Figure 5 , both ends of the lock rod positioning seat 2 are respectively provided with an upper clamping plate assembly 13 and a lower clamping plate assembly 14, and the upper clamping plate assembly 13 and the lower clamping plate assembly 14 are respectively fixedly connected with the end frame 1. The upper clamping plate assembly 13 and the lower clamping plate assembly 14 respectively include an outer side plate 9 and an inner side plate 8, the outer side plate 9 is arranged on the outer side of the outer wall of the end frame 1, and the inner side plate 8 is arranged on the inner side of the outer wall of the end frame 1, the inner side plate 8 is provided with a threaded hole, and the outer side plate 9, the outer wall of the end frame 1 and the inner side plate 8 are sequentially fixedly connected by screws, as shown in Figure 6 . The lock rod positioning seat 2 is positioned and fixed by the upper clamping plate assembly 13 and the lower clamping plate assembly 14, so as to avoid machining the threaded hole on the nylon lock rod positioning seat 5, and the lock rod positioning seat 5 can simultaneously close the opening at the end of the end frame 1, and the state after the end frame 1 is locked has the effect of increasing the strength.
[0029] The pressure plate 3, fixedly connected to the locking rod 2, is positioned below the inner plate 8 of the lower clamping plate assembly 13. The contact position of the inner plate 8 and the pressure plate 3 corresponds to the position where the locking notch 11 separates from the locking hook 6. When the locking rod 2 moves upward, the locking notch 11 separates from the locking hook 6, and the locking mechanism enters the open state. The open position of the locking rod 2 coincides with the interference between the pressure plate 3 and the inner plate 8. This clearly indicates to the operator that the locking mechanism has completed its opening operation, preventing the pressure plate from separating from the spring guide column.
[0030] The locking structure for the windshield inside a rail vehicle bellows, described in this utility model, comprises a locking rod within an end frame. The locking rod moves up and down within the windshield end frame to engage or disengage with a locking hook on a transition plate on the vehicle body, thereby connecting the entire bellows assembly to the transition plate. When the locking rod moves upward, a locking notch on the locking rod aligns with a locking hook on the transition plate, separating the two and achieving the opening function. When the locking rod moves downward, the locking notch on the locking rod moves downward, causing the locking rod to engage with the locking hook on the transition plate, achieving the locking function. As the locking rod moves downward, the pressure plate attached to the rod moves downward. This pressure plate presses against the compression spring and moves it downward along the spring guide post, compressing the spring. As the rod moves upward, the pressure plate attached to the rod moves upward, causing the compression spring to move upward with it. At the rod's maximum upward movement, the compression spring remains compressed, providing upward force. When the rod opens, its own weight tends to cause it to move downward. The compression spring counteracts the rod's own weight, keeping the rod in a fixed position and preventing it from falling into the locked state. The spring guide post guides and supports the compression spring, ensuring controlled deformation during the spring compression process. When the rod is open, the pressure plate interferes with the lower stop plate, preventing it from moving upward excessively and disengaging from the spring guide post. This also signals to the operator that the opening operation is complete. The spring guide post and compression spring are located within the cavity of the end frame profile, completely eliminating any assembly interference with other transition plate components. This reduces design and assembly interference checks, as well as repeated design and product modifications caused by changes to transition plate components.
[0031] The locking structure of the windshield in the bellows of a rail vehicle described in the utility model has a simple structure, is easy to assemble and disassemble, has high efficiency, saves labor, is highly safe, and has low maintenance costs. Its design is safe and reliable, has good compatibility, reduces complex coordination with other components, and shortens the design and development cycle of serialized products.
