Description
Technical Field
[0001] This utility model relates to the field of locomotive side sliding window technology, and in particular to a locomotive side sliding window clamping device. Background Technology
[0002] The design requirements for the locomotive side window clamping device are convenient operation, simple maintenance, and low manufacturing cost. Currently, existing technology typically uses a combination of an eccentric handle and a limit pin. However, this design is subject to continuous vibration during locomotive operation, and the eccentric handle is prone to wobbling when the sliding window is open. When the wobbling amplitude exceeds a certain range, it will interfere with the window closing operation and may even prevent the sliding window from closing properly.
[0003] Therefore, how to effectively prevent the eccentric handle from shaking when the active window is opened has become a technical problem that urgently needs to be solved in this field. Utility Model Content
[0004] In view of the technical problem of how to effectively prevent the eccentric handle from shaking when the movable window is opened, the purpose of this utility model is to provide a locomotive side window clamping device that can effectively limit the shaking of the eccentric handle when the movable window is opened.
[0005] A locomotive side window clamping device includes: Support bracket, installed on the fixed window frame; An eccentric handle is rotatably connected to the support base via a rotating shaft; The magnetic positioning assembly includes a first magnetic element and a second magnetic element, wherein the first magnetic element is disposed on the eccentric handle and the second magnetic element is disposed on the support base; When the active window is open and the eccentric handle is rotated to the unlocked position, the first magnetic component and the second magnetic component are magnetically attracted to limit the shaking of the eccentric handle.
[0006] Furthermore, one of the first magnetic attractor and the second magnetic attractor is a permanent magnet, and the other is a permanent magnet or a magnetic conductor.
[0007] Furthermore, the permanent magnet is a neodymium iron boron magnet.
[0008] Furthermore, the eccentric handle includes: Pressure cam; The handle is integrally formed with the clamping cam. The operator can drive the clamping cam to clamp or disengage the locking part on the movable window frame by rotating the handle.
[0009] Furthermore, the first magnetic element is embedded in the handle, and the second magnetic element is correspondingly embedded in the side wall of the support base.
[0010] Furthermore, the handle is provided with a first mounting hole, and the side wall of the support is provided with a second mounting hole; The first magnetic component is adhered to the first mounting hole, and the second magnetic component is adhered to the second mounting hole.
[0011] Furthermore, the gripping end of the handle away from the clamping cam is provided with anti-slip texture.
[0012] Furthermore, the anti-slip texture includes multiple parallel straight raised lines.
[0013] Furthermore, the clamping cam is fixed to the end of the rotating shaft by a fixing screw.
[0014] Furthermore, when the eccentric handle is rotated to the unlocked position, the handle retracts to the same side of the support; when the eccentric handle is rotated to the pressing position, the handle extends to the opposite side of the support.
[0015] Compared with the prior art, the locomotive side window pressing device provided in this embodiment of the utility model has at least the following technical effects: The locomotive side window clamping device includes a support base, an eccentric handle, and a magnetic positioning assembly. The support base is mounted on a fixed window frame. The eccentric handle is rotatably connected to the support base via a rotating shaft. The magnetic positioning assembly includes a first magnetic element and a second magnetic element. The first magnetic element is mounted on the eccentric handle, and the second magnetic element is mounted on the support base. When the sliding window is open and the eccentric handle is rotated to the unlocked position, the first and second magnetic elements magnetically attract each other to limit the wobbling of the eccentric handle. This design effectively reduces the wobbling of the eccentric handle caused by vibrations during locomotive operation, avoiding the problem that excessive wobbling may interfere with or hinder the window closing operation, thereby improving the safety and smoothness of operation of the sliding window in the open state.
