[0028] like Figure 1-6 This embodiment provides a safety switch device 001 for a bulldozer, including a safety switch mechanism 2 and a fixing mechanism 3 for mounting the safety switch mechanism 2. The safety switch mechanism 2 includes an operating handle 21, a bearing 22 on the operating handle 21, a rotating shaft 23 and a micro switch 24 connected to the bearing 22, and a tension spring 25 mounted on the rotating shaft 23 for fixing the position of the operating handle 21. The fixing mechanism 3 includes an assembly assembly 32 and a control box 31. The safety switch mechanism 1 is mounted on the inner wall of the control box 31 via the assembly assembly 32. The safety switch mechanism 1 is detachably mounted on the assembly assembly 32, and the assembly assembly 32 is detachably mounted on the inner wall of the control box 31. The control box 31 has a groove 311 on one side, and one end of the shaft seat 22 of the safety switch mechanism 1 is engaged in the groove 311. The operating handle 21 is on the outside of the control box 31. The control box 31 includes a mounting base 312, which is mounted on the base plate frame 4 of the bulldozer. The control box 31 also includes a sealing gasket 313, which is placed along the edge of the upper surface of the control box 31 to seal the groove 311.

[0029] In this embodiment, as Figure 5As shown, the assembly component 32 includes a mounting plate 321, a first support plate 322, a second support plate 323, and two connectors 324. The first support plate 322 and the second support plate 323 are detachably mounted on the mounting plate 321. The two connectors 324 are respectively mounted on the two top ends of the mounting plate 321. The mounting plate 321 is mounted on the inner wall of the control box 31 through the two connectors 324. The safety switch mechanism 2 is detachably connected to the first support plate 322 by bolts 325 and is limited by the second support plate 323.

[0030] In this embodiment, as Figure 4-5 As shown, the mounting plate 321 is L-shaped, with an extension plate extending outward from the middle portion. One side of the extension plate is used to mount the first support plate 322. Several mounting holes 3211 are provided at the top of both ends of the mounting plate 321. The second support plate 323 is mounted on the lower side of the middle portion of the mounting plate 321. The safety switch mechanism 2 is connected to the first support plate 322 by bolts 325 and is limited by the second support plate 323. The first support plate 322 is U-shaped, with first mounting holes 3231 at the top of both ends. The second support plate 324 is an irregularly shaped assembly plate, including a main plate 3231, a large side plate 3232 vertically fixed to the top of the main plate 3231, and a small side plate 3233 vertically mounted to the bottom of the main plate 3231. The main plate 3231 is fixed to the mounting plate 321. The large side plate 3232 has a second mounting hole 3234, and the small side plate 3233 has a through hole 3235.

[0031] In this embodiment, as Figure 5 As shown, the connector 324 includes a pad 3241, a screw 3242, and a washer 3243. The pad 3241 has a plurality of small holes 32411 evenly distributed on it.

The screw 3242 passes through the mounting hole 3211 and the small holes 32411 of the pad 3241, thus mounting the mounting plate 321 onto the inner side wall of the control box 31.

[0032] In this embodiment, as Figure 6 As shown, the safety switch device 001 is installed on the bulldozer base plate frame 4. In the initial state (normal shutdown state), the operating handle 21 is vertically downward. To start the bulldozer, the operating handle 21 needs to be rotated 90° around the axle seat 22 to be parallel to the ground. When the operating handle 21 rotates, it drives the rotating shaft 23 connected to the axle seat 22 to rotate by the same angle. At this time, the axle seat 22 separates from the micro switch 24, and the arc-shaped surface at the far end of the rotating shaft 23 presses against the micro switch 24, and the bulldozer starts.

[0033] This embodiment discloses a safety switch device 001 for a bulldozer. The safety switch device 001 includes a safety switch mechanism 2 and a fixing mechanism 3 for fixing the safety switch mechanism 2. The fixing mechanism 3 includes an assembly component 32 and an operating box 31. The safety switch mechanism 2 is mounted on the inner wall of the operating box 31 via the assembly component 32. The safety switch mechanism 2 is detachably mounted on the first support plate 322 of the assembly component 32 via bolts 325. The assembly component 32 is detachably mounted on the inner wall of the operating box 31. This utility model's safety switch device 001, by first assembling the safety switch mechanism 2 outside the operating box 31 onto the assembly component 32, and then assembling the safety switch mechanism 2 and the assembly component 32 together into the operating box 31, forms a complete safety switch device 001. This design allows for controllable dimensional accuracy and simplifies assembly, maintenance, and repair.
