[0006] Preferably, the slider assembly is provided with a limit pin.

[0007] In practical applications, the control mechanism of the subway car end travel protection device further includes: a protective box; the slider assembly, the limit pin, and the protection switch are located inside the protective box.

[0008] The connecting rod is fitted with a rubber protective sleeve on its outer side.

[0009] Specifically, the rotating knob, the connecting piece, the connecting rod, the slider assembly, the limiting pin, and the protective box are all made of stainless steel.

[0010] Furthermore, the protective box is connected to the equipment box under the vehicle by bolts.

[0011] Compared with existing technologies, the control mechanism of the subway car end travel protection device of this utility model has the following advantages:

[0012] In the control mechanism of the subway car end travel protection device provided by this utility model, the rotating shaft of the rotary knob is connected to the connecting rod through the connecting piece, and the connecting rod is connected to the slider assembly. The slider assembly is used to control the lifting and lowering of the contacts of the protection switch to realize the opening and closing function of the protection switch. Therefore, the control mechanism of the subway car end travel protection device provided by this utility model does not require any tools during operation. It only requires manual rotation of the rotary knob, which drives the connecting piece, so that the connecting piece drives the slider assembly through the connecting rod, and controls the protection switch to realize the opening and closing function through the slider assembly. Thus, the control mechanism has a simple structure, strong versatility, convenient operation, and easy identification of the fastening state, thereby reducing the daily inspection, disassembly and installation time and enabling single-person operation.

[0017] For ease of understanding, the control mechanism of the subway car end travel protection device provided in the embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0018] This utility model embodiment provides a control mechanism for a subway car end travel protection device, such as... Figure 1 and Figure 2 As shown, it includes: a rotating knob 1, the rotating shaft 11 of the rotating knob 1 is connected to the connecting rod 21 through the connecting piece 2, and the connecting rod 21 is connected to the slider assembly 3; the slider assembly 3 is used to control the lifting and lowering of the contacts of the protection switch 4 in linkage, so as to realize the opening and closing functions of the protection switch 4.

[0019] Compared with the prior art, the control mechanism of the subway car end travel protection device described in this embodiment of the utility model has the following advantages:

[0020] In the subway car end travel protection device control mechanism provided in this embodiment of the utility model, since the rotating shaft 11 of the rotating shaft knob 1 is connected to the connecting rod 21 through the connecting piece 2, and the connecting rod 21 is connected to the slider assembly 3; the slider assembly 3 is used to control the lifting and lowering of the contacts of the protection switch 4 in linkage, so as to realize the opening and closing function of the protection switch 4; therefore, the subway car end travel protection device control mechanism provided in this embodiment of the utility model does not require any tools during operation. It only requires manual rotation of the rotating shaft knob 1, and the rotating shaft knob 1 drives the connecting piece 2, so that the connecting piece 2 drives the slider assembly 3 through the connecting rod 21, and controls the protection switch 4 to realize the opening and closing function through the slider assembly 3. Thus, the control mechanism has a simple structure, strong versatility, convenient operation, and easy identification of the fastening state, thereby reducing the daily inspection, disassembly and installation time, and enabling single-person operation.

[0021] Preferably, such as Figure 1 and Figure 2 As shown, the slider assembly 3 can be equipped with a limit pin 31, which makes the control mechanism more stable and avoids slippage.
