Therefore, those skilled in the art have provided a fixing device for the body of a radiator motor mounting plate on a railcar to solve the problems mentioned in the background art. Utility Model Content

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0005] A fixing device for a radiator motor mounting plate body of a railcar includes two clamping plates and a mounting plate body for mounting a radiator motor installed between the two clamping plates. The inner sides of the two clamping plates are provided with slots, and the two ends of the mounting plate body are respectively engaged in the two slots.

[0020] The present invention will be further described in detail below with reference to embodiments:

[0021] This utility model discloses a fixing device for the motor mounting plate body of a railcar radiator. (Refer to...) Figure 1-5 It includes two clamping plates 1 and a mounting plate body 2 installed between the two clamping plates 1 for installing a radiator motor. The inner sides of the two clamping plates 1 are provided with slots 3. The two ends of the mounting plate body 2 are respectively locked in the two slots 3. Fixing holes 4 are provided around the two clamping plates 1. Bolts 5 for mounting on the railcar are installed in the fixing holes 4. Adjustment mechanism for adjusting the distance between the two clamping plates 1 is installed at the bottom of the two clamping plates 1.

[0022] By adopting the above technical solution, this utility model, through its adjustable mechanism, facilitates the placement of both ends of the mounting plate body 2 into the two slots 3. The elastic force of the spring 16 drives the drive plate 6 to move towards the center, thereby causing the first movable block 8 to move within the first movable groove 7 and the second movable block 15 to move within the second movable groove 13. This allows the two clamping plates 1 to clamp the mounting plate body 2. Furthermore, by driving the drive handle 21 to rotate, the two screws 11 rotate via the transmission of the rotating wheel 20, thereby driving the adjusting block 12 to move. The semi-circular shape of the adjusting block 12 compresses the two clamping plates 1 towards the center, thus fixing the mounting plate body 2. This facilitates the fixing of mounting plate bodies 2 of various sizes, thereby improving the applicability of the device.

[0023] Reference Figure 1-5The adjustment mechanism includes two drive plates 6, one end of which is fixedly connected to one side of two clamping plates 1. Each clamping plate 1 has a first movable groove 7 at its top, and a first movable block 8 is movably installed within each of the two first movable grooves 7. A first limiting rod 9 is fixedly installed within each of the two first movable grooves 7, and the two first movable blocks 8 are movably connected to the two first limiting rods 9. Both the two first movable grooves 7 and the two first movable blocks 8 are T-shaped. Bearings 10 are installed at the bottom of each of the two first movable blocks 8, and screws 11 are rotatably mounted on each of the two bearings 10. Adjusting blocks 12 are threaded onto the bottom of each of the two screws 11. The adjusting blocks 12 are semi-circular, and the bottom ends of the two clamping plates 1 are located at both ends inside the adjusting blocks 12.

[0024] By adopting the above technical solution, the adjustment block 12 facilitates the rotation of the drive handle 21 through the drive, and the two screws 11 can be rotated through the transmission of the rotating wheel 20, thereby driving the adjustment block 12 to move. The semi-circular arrangement of the adjustment block 12 can squeeze the two clamping plates 1 to move towards the center, thereby fixing the mounting plate 2 body.

[0025] Reference Figure 1-5 Each of the two drive plates 6 has a second movable groove 13 on both sides. A second limiting rod 14 is fixedly installed in each of the two second movable grooves 13. A second movable block 15 is movably installed in each of the two second movable grooves 13, and the two second movable blocks 15 are movably connected to the two second limiting rods 14 respectively. A spring 16 is fitted onto each of the two second limiting rods 14. A fixing rod 17 is fixedly installed on each of the two second movable blocks 15, and a fixing plate 18 is fixedly installed at the bottom end of the fixing rod 17. A third movable groove 19 is opened in the middle of each of the two drive plates 6, and two screws 11 are movably disposed in the two third movable grooves 19 respectively. Both screws 11 are rotatably connected to the fixing plate 18, and a rotating wheel 20 is fixedly installed through the fixing plate 18 at the bottom end of each screw 11. The two rotating wheels 20 are connected by a transmission belt. A drive handle 21 is fixedly installed at the bottom end of one screw 11.

[0026] By adopting the above technical solution, the first movable block 8, the second movable block 15 and the spring 16 are set so that the two ends of the mounting plate body 2 are respectively set in the two slots 3. The elastic force of the spring 16 can drive the drive plate 6 to move towards the center, so that the first movable block 8 moves in the first movable groove 7 and the second movable block 15 moves in the second movable groove 13, so that the two clamping plates 1 can clamp the mounting plate body 2, thereby initially clamping and fixing the mounting plate body 2.

[0027] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
