[0020] Reference Figure 1-7The forklift parking brake switch device comprises a socket 10, a mounting seat 11 and a self-locking top column 5 are fixed on the top of the mounting socket 10, an LED lamp 3 is fixed inside the mounting seat 11, a deflection sleeve 12 is movably mounted on the outside of the mounting seat 11, a light-transmitting pattern 4 is arranged on the surface of the deflection sleeve 12, a self-locking slider 1 is movably mounted on the surface of the deflection sleeve 12 and located on one side of the light-transmitting pattern 4, a self-locking top column 7 is fixed on the bottom of the self-locking slider 1, and the self-locking top column 5 is in contact with the self-locking top column 7.
[0021] A slide groove 13 for installing the self-locking slider 1 is provided on the surface of the deflection sleeve 12, and a docking column 2 is fixed to the side wall of the slide groove 13. A docking groove 6 is provided on the side wall of the self-locking slider 1, and the docking column 2 is docked with the docking groove 6. A spring is mounted on the surface of the docking column 2, and the spring is placed in the docking groove 6. A spring is installed on the deflection sleeve 12, which can give the self-locking slider 1 a forward force. The deflection sleeve 12 rotates to achieve gear adjustment. When the position is at POS3, the self-locking slider 1 is pushed out by the spring. At this time, the upper position of the lock top column and the lower position of the self-locking top column 5 are in the same vertical plane, and they support each other to prevent people from pressing down to the positions of POS2 and POS1.
[0022] Fixing buckles 9 are symmetrically fixed to the side walls of the self-locking slider 1 , and friction patterns 8 are formed on the upper surface of the self-locking slider 1 .
[0023] The side wall of the assembly seat 11 is provided with a lamp groove for fixing the LED lamp 3, and the light-transmitting pattern 4 is located directly above the LED lamp 3. When the gear is in POS3, the LED lamp 3 is powered on and lights up. The light-transmitting pattern 4 is a carved pattern, and the thickness of the pattern is reduced so that the light can be transmitted through the pattern in a dim environment, so that the driver clearly knows that the forklift is in a braking state. At the same time, the carved pattern saves costs.
[0024] The side wall of the assembly seat 11 is symmetrically fixed with docking ears 14 for movably mounting the deflection sleeve 12.
[0025] When the device is in use, the brake switch has three gears, namely POS1, POS2 and POS3. When the gear is in POS1, the brake is released and the vehicle can travel normally; when the gear is in POS2, it is neutral and the state of the previous gear is not changed; when the gear is in POS3, the forklift is in a braking state; when the forklift is in POS3, its self-locking slide block 1 plays a role to prevent accidental triggering and returning to POS1 and POS2 states, and the self-locking top column 7 and the self-locking top column 5 form a self-locking state. When the switch is in POS When in gear position 3, the upper self-locking top column 7 and the lower self-locking top column 5 will press against each other, preventing the driver from pressing the cover to the POS2 and POS1 positions to achieve safe self-locking. When unlocking is required, the self-locking slider 1 is pushed by the finger to separate and stagger the upper self-locking top column 7 and the lower self-locking top column 5, so that the gear can be unlocked. Subsequently, downshift adjustment can be made. After completing the gear adjustment, release the self-locking slider 1. The self-locking slider 1 does not work during the upshift process. Only when downshifting at POS3 does the self-locking slider 1 work, and the self-locking slider 1 needs to be manually unlocked to achieve the downshift operation.
