Abstract
Description
Technical Field
[0001] The utility model relates to a motor vehicle window installation, adjustment and fixing mechanism, belonging to the technical field of rail vehicles. Background Art
[0002] EMU, also known as "EMU train", is a type of modern train, consisting of several powered vehicles (EMU) and non-powered vehicles (trailers). The train operates in a fixed formation mode during its normal service life.
[0003] The existing EMU window fixing methods all use a clamping mechanism (a fixing mechanism for the window on the car body), and it is impossible to achieve adjustment through the fixing mechanism to ensure that the outer surface of the window is flush with the outer surface of the car body. The adjustment method is basically achieved by padding adjustment gaskets. This method is time-consuming and material-intensive, and cannot be adjusted into place in one go; and it requires four people to operate (one person outside the car to determine whether it is flush, two people inside the car to hold the window, and one person to install the adjustment gasket), which is labor-intensive. Summary of the invention
[0004] The utility model aims to overcome the above-mentioned shortcomings and provides a motor vehicle window installation, adjustment and fixing mechanism.
[0005] The purpose of the utility model is achieved in this way:
[0006] A motor vehicle window installation, adjustment and fixing mechanism, which is characterized by comprising a window outer frame, a fixing seat, a fastening nut, an adjusting screw sleeve and a fastening bolt;
[0007] The lower part of the fixing seat is fixedly arranged on the surface of the vehicle body, and the adjusting screw sleeve is arranged on the upper part of the fixing seat, and the two are threadedly matched; the fastening nut is sleeved on the adjusting screw sleeve, the fastening nut and the adjusting screw sleeve are threadedly matched, and the fastening nut is against the upper part of the fixing seat;
[0008] The upper part of the vehicle window frame is fixedly connected to the inner side of the vehicle window surface; the rod end of the fastening bolt passes through the adjusting screw sleeve and is fixedly connected to the lower part of the vehicle window frame.
[0009] Furthermore, a stop washer is provided between the cap portion of the fastening bolt and the cap portion of the adjusting nut.
[0010] Furthermore, it includes a threaded fixing block, the lower part of the window frame has a cavity, the threaded fixing block is fixedly arranged in the cavity, the rod end of the fastening bolt passes through the adjusting screw sleeve and extends into the cavity, and the threaded fixing block is sleeved on the rod end of the fastening bolt.
[0011] Furthermore, the fixing seat is L-shaped.
[0012] Compared with the prior art, the beneficial effects of the utility model are:
[0013] The utility model discloses a motor vehicle window installation adjustment and fixing mechanism, which reduces the difficulty of repeated disassembly during installation, improves installation efficiency, improves adjustment accuracy, reduces work intensity, and now only requires two people to operate (one person determines flushness outside the vehicle, and the other person adjusts and tightens). BRIEF DESCRIPTION OF THE DRAWINGS
[0014] Figure 1 Schematic diagram of the adjustment and fixing mechanism for the EMU window installation.
[0015] In the figure:
[0016] Vehicle window frame 1, cavity 1.1, fixing seat 2, threaded fixing block 3, fastening nut 4, adjusting screw sleeve 5, stop washer 6, fastening bolt 7, vehicle window surface 8, vehicle body surface 9. DETAILED DESCRIPTION
[0017] The following is a further description of the specific implementation of the present invention in conjunction with the accompanying drawings and embodiments. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and cannot be used to limit the protection scope of the present invention.
[0018] See also Figure 1 The utility model discloses a motor vehicle window installation adjustment and fixing mechanism, comprising a window outer frame 1, a fixing seat 2, a threaded fixing block 3, a fastening nut 4, an adjusting screw sleeve 5, a stop washer 6 and a fastening bolt 7.
[0019] The upper part of the vehicle window outer frame 1 is fixedly connected to the inner side of the vehicle window surface 8 , and the lower part of the vehicle window outer frame 1 has a cavity 1 . 1 .
[0020] The fixing seat 2 is L-shaped, the lower part of the fixing seat 2 is fixedly arranged on the extension section of the vehicle body surface 9, the adjusting screw sleeve 5 is arranged on the upper part of the fixing seat 2, and the two are threadedly matched; the fastening nut 4 is sleeved on the adjusting screw sleeve 5, and the fastening nut 4 is against the upper part of the fixing seat 2.
[0021] The threaded fixing block 3 is fixedly arranged in the cavity 1.1, the rod portion of the fastening bolt 7 passes through the adjusting screw sleeve 5 and extends into the cavity 1.1, and the threaded fixing block 3 is sleeved on the rod end of the fastening bolt 7.
[0022] A stop washer 6 is provided between the cap of the fastening bolt 7 and the cap of the adjusting nut 5 , which can effectively prevent the fastening bolt 7 from loosening or falling off.
[0023] The tightening nut 4 is threadedly matched with the adjusting screw sleeve 5, and the adjusting screw sleeve 5 is threadedly matched with the upper portion of the fixing seat 2. The adjusting screw sleeve 5 is fixed to the fixing seat 2 by a double-nut tightening mode, and is effectively prevented from loosening.
