Description

Technical Field

[0001] This invention relates to a pivot structure and a movable window, belonging to the technical field of window system design for railway passenger cars and EMU trains. Background Technology

[0002] For safety reasons, movable windows need to be installed on railway passenger cars and EMUs to meet the requirements of rapid emergency ventilation in emergency situations. However, with the increase in the operating speed of railway passenger cars and EMUs and the increasing complexity of the operating environment (frequent entry and exit from tunnels generates alternating loads), the surface of the movable window is subjected to higher alternating loads, requiring the movable window structure to withstand greater pressure.

[0003] The operable windows primarily rotate via a pivot. This pivot not only rotates but also bears the pressure of the sealing strip when the window is closed and the alternating load pressure on the window surface during vehicle operation. Therefore, it has the following drawbacks: First, with only the pivot bearing the load, its rigidity and strength are insufficient; when the window is subjected to excessive force, the pivot will deform. Second, excessive rotation of the pivot will cause wear between the bushing and the core. Furthermore, both deformation and wear of the pivot can prevent the window's sealing strip from tightening properly, leading to leaks, air leaks, and whistling. Excessive deformation can even prevent the window from opening, rendering it ineffective.

[0004] It is evident that, in order to solve the aforementioned technical problem of the inability to press the sealing strip of the movable window tightly due to the deformation and wear of the pivot, there is an urgent need for a pivot structure and a movable window. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a pivot structure and a movable window. By setting a self-locking lock cylinder, a pivot bushing, a self-locking lock sleeve, and a pivot core, when the movable window is closed, the self-locking lock cylinder is locked into the self-locking lock sleeve. When the movable window is opened, the self-locking lock cylinder rotates with the pivot and simultaneously disengages from the self-locking lock sleeve, thus unlocking the window. This invention can solve the problems of rain leakage, air leakage, whistling, and inability to open the movable window caused by the inability of the movable window sealing strip to be pressed tightly due to pivot deformation and wear.

[0006] To achieve the above objectives / to solve the above technical problems, the present invention is implemented using the following technical solution:

[0007] In a first aspect, the present invention provides a rotating shaft structure, including a self-locking lock core, a rotating shaft sleeve, a self-locking lock sleeve, and a rotating shaft core;

[0008] The self-locking lock cylinder and the rotating shaft sleeve are fixed to the movable sash window frame, and the self-locking lock sleeve and the rotating shaft core are fixed to the fixed sash window frame. The self-locking lock cylinder and the self-locking lock sleeve are adapted to each other, and the rotating shaft core and the rotating shaft sleeve are adapted to each other. When the movable sash is closed, the self-locking lock cylinder is engaged in the self-locking lock sleeve. When the movable window is opened, the self-locking lock cylinder rotates with the rotating shaft and simultaneously disengages from the self-locking lock sleeve, thereby unlocking the window.

[0009] Furthermore, the rotating shaft sleeve and the rotating shaft core adopt a 3 / 4 circle surrounding structure design.

[0010] Furthermore, the shaft sleeve and the shaft core are fitted with zero clearance.

[0011] Furthermore, the rotating shaft sleeve and the rotating shaft core adopt a conical surrounding structure.

[0012] Furthermore, it also includes a movable fan opening limit rod and a movable fan opening limit block, wherein the movable fan opening limit rod is fixed to the rotating shaft sleeve, and the movable fan opening limit block is disposed on the side of the rotating shaft core and is detachably connected to the fixed window frame.

[0013] Furthermore, it also includes an outer glass retaining strip mounting groove and an inner glass retaining strip mounting groove, which are respectively set on the inner and outer sides of the connection end between the fixed window frame and the fixed sash.

[0014] Furthermore, it also includes a second outer glass retaining strip mounting groove and a second inner glass retaining strip mounting groove, which are respectively set on the inner and outer sides of the connection end between the movable sash window frame and the movable sash.

[0015] Furthermore, it also includes an outer sealing strip mounting groove and an inner sealing strip mounting groove, which are respectively set on the inner and outer sides of the movable sash window frame at the end away from the movable sash.

[0016] Secondly, the present invention provides a movable vehicle window, including a movable sash, a fixed sash, and the aforementioned pivot structure, wherein the movable sash and the fixed sash are connected by the pivot structure.

[0017] Compared with the prior art, the beneficial effects achieved by the present invention are as follows:

[0018] The rotating shaft structure provided by this invention, by setting a self-locking lock cylinder, a rotating shaft sleeve, a self-locking lock sleeve, and a rotating shaft core, allows the self-locking lock cylinder to engage with the self-locking lock sleeve when the movable window is closed, and to disengage from the self-locking lock sleeve when the movable window is opened, thereby unlocking the window. This solves the problems of rain leakage, air leakage, whistling, and inability to open caused by the inability of the movable window sealing strip to be pressed tightly due to the deformation and wear of the rotating shaft.

[0019] The rotating shaft structure provided by the present invention, by setting a movable fan opening limit rod and a movable fan opening limit block, when the movable fan rotates to a certain angle, the movable fan opening limit rod pushes against the movable fan opening limit block to ensure the opening angle of the movable fan. At the same time, since the movable fan opening limit block is detachably connected to the fixed window frame, the movable fan opening limit block can be removed and rotated to a specific angle before the rotating shaft bushing and the rotating shaft core can be installed and disassembled.

[0020] The movable window provided by this invention connects the movable sash and the fixed sash through the aforementioned pivot structure, which can effectively solve the problems of rain leakage, air leakage, whistling, and inability to open caused by the inability of the movable window sealing strip to be pressed tightly due to the deformation and wear of the pivot.

Those skilled in the art will understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0033] Example 1:

[0034] like Figure 1-3 As shown, this embodiment provides a rotating shaft structure, including a self-locking lock core 2, a rotating shaft sleeve 4, a self-locking lock sleeve 5, and a rotating shaft core 7;

[0035] The self-locking lock cylinder 2 and the rotating shaft sleeve 4 are fixed to the movable window frame 3 of the movable sash 1, and the self-locking lock sleeve 5 and the rotating shaft core 7 are fixed to the fixed window frame 8 of the fixed sash 9. The self-locking lock cylinder 2 is adapted to the self-locking lock sleeve 5, and the rotating shaft core 7 is adapted to the rotating shaft sleeve 4. When the movable sash 1 is closed, the self-locking lock cylinder 2 is engaged in the self-locking lock sleeve 5. When the movable window is opened, the self-locking lock cylinder 2 rotates with the rotating shaft and simultaneously disengages from the self-locking lock sleeve 5, thereby unlocking the window.

[0036] In some embodiments, to ensure reliable shaft connection, such as Figure 4 and Figure 5 As shown, the rotating shaft sleeve 4 and the rotating shaft core 7 adopt a 3 / 4 circle surrounding structure design.

[0037] In some embodiments, to enable the rotating shaft sleeve 4 to rotate stably around the rotating shaft core 7, such as... Figure 6 and Figure 7 As shown, the rotating shaft sleeve 4 and the rotating shaft core 7 are fitted with zero clearance.

[0038] In some embodiments, to ensure that the self-locking lock cylinder 2 and the self-locking lock sleeve 5 can easily slide into and out of the self-locking lock sleeve 5 even if errors occur due to deformation of the movable fan, so as to complete the self-locking and meet the load-bearing functions in the three directions of vehicle interior, exterior, and downward, such as... Figure 6 and Figure 7 As shown, the rotating shaft sleeve 4 and the rotating shaft core 7 adopt a conical surrounding structure.

[0039] In some embodiments, to ensure the opening angle of the movable sash, a movable sash opening limiting rod 6 and a movable sash opening limiting block 10 are also included. The movable sash opening limiting rod 6 is integral with the rotating shaft sleeve 4, and the movable sash opening limiting block 10 is disposed on the side of the rotating shaft core 7 and detachably connected to the fixed window frame 8. When the movable sash 1 rotates to a certain angle (in this embodiment, the movable sash 1 rotates inward to 30°), the movable sash opening limiting rod 6 abuts against the movable sash opening limiting block 10. Since the movable sash opening limiting block 10 is detachably connected to the fixed window frame 8, the movable sash opening limiting block 10 must be removed, and the movable sash 1 must rotate inward to a range of 35° to 50° before the rotating shaft sleeve 4 and the rotating shaft core 7 can be installed and disassembled. Figure 8 As shown.

[0040] In some embodiments, such as Figure 5 As shown, in order to realize the installation between the fixed window frame 8 and the inner and outer glass, it also includes an outer glass retainer mounting groove 11 and an inner glass retainer mounting groove 12, which are respectively set on the inner and outer sides of the connection end between the fixed window frame 8 and the fixed sash 9.

[0041] In some embodiments, such as Figure 4 As shown, in order to realize the installation between the movable sash 1 and the inner and outer glass, it also includes an outer glass retaining strip mounting groove 2 13 and an inner glass retaining strip mounting groove 2 14, which are respectively set on the inner and outer sides of the connection end between the movable sash window frame 3 and the movable sash 1.

[0042] In some embodiments, such as Figure 4 As shown, in order to realize the installation between the movable sash 1 and the inner and outer sealing strips, an outer sealing strip mounting groove 15 and an inner sealing strip mounting groove 16 are also included, which are respectively set on the inner and outer sides of the movable sash window frame 3 at the end away from the movable sash 1.

[0043] In summary, the pivot structure provided in this embodiment, by setting a self-locking lock cylinder 2, a pivot bushing 4, a self-locking sleeve 5, and a pivot shaft core 7, allows the self-locking lock cylinder 2 to engage with the self-locking sleeve 5 when the movable window 1 is closed. When the movable window is opened, the self-locking lock cylinder 2 rotates with the pivot shaft, simultaneously disengaging from the self-locking sleeve 5, thus unlocking the window. This solves the problems of rain leakage, air leakage, whistling, and inability to open caused by the inability of the movable window sealing strip to be properly pressed due to pivot shaft deformation and wear. Furthermore, by setting a movable window opening limit... When the movable fan 1 rotates to a certain angle (in this embodiment, the movable fan 1 rotates inward to 30°), the movable fan opening limit rod 6 and the movable fan opening limit block 10 are positioned so that the opening angle of the movable fan 1 is guaranteed. At the same time, since the movable fan opening limit block 10 is detachably connected to the fixed window frame 8, the movable fan opening limit block 10 can be removed and the movable fan 1 can rotate inward to a range of 35° to 50° before the rotating shaft sleeve 4 and the rotating shaft core 7 can be installed and removed.

[0044] Example 2:

[0045] This embodiment provides a movable vehicle window, including a movable sash 1, a fixed sash 9, and the aforementioned pivot structure. The movable sash 1 and the fixed sash 9 are connected by the pivot structure. Connecting the movable sash 1 and the fixed sash 9 through the aforementioned pivot structure can effectively solve the problems of rain leakage, air leakage, whistling, and inability to open caused by the movable window sealing strip failing to press tightly due to pivot deformation and wear.

[0046] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
