[0025] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0026] Please refer to Figure 1-Figure 3 The utility model discloses a foot switch for a forklift, which is installed on a platform of the forklift. The foot switch includes:

[0027] A housing 100 connected to the platform, wherein a fixed first trigger member 140 and a movable second trigger member 150 are provided on the housing 100;

[0028] The cover plate 200 is arranged on the shell 100, and the cover plate 200 can move in the height direction relative to the shell 100 to drive the second trigger member 150 to connect with or separate from the first trigger member 140; the cover plate 200 has a first position and a second position. When in the first position, the upper surface of the cover plate 200 protrudes from the platform setting, and the first trigger member 140 is separated from the second trigger member 150; when in the second position, the upper surface of the cover plate 200 is flush with the surface of the platform, and the first trigger member 140 is connected with the second trigger member 150.

[0029] Specifically, the present application realizes the connection and disconnection of the first trigger member 140 and the second trigger member 150 by moving the cover plate 200 up and down, thereby realizing the connection and disconnection of the circuit. When the cover plate 200 is stepped on to the second position, the upper surface of the cover plate 200 is flush with the platform surface, so that the cover plate 200 forms a flat surface with the standing surface, and the operator can stand steadily to reduce the danger.

[0030] Furthermore, the cover plate 200 includes a main board 210, and the main board 210 is located above the housing 100;

[0031] A plurality of limiting members 110 are disposed on the housing 100 , and the upper surfaces of the limiting members 110 can abut against the lower surface of the main board 210 to limit the cover plate 200 from moving in a direction toward the housing 100 .

[0032] Specifically, the limiting member 110 abuts against the main board 210 to prevent the cover plate 200 from continuing to move downward, and the cover plate 200 can be supported to prevent the operator from shaking left and right when standing, thereby enhancing safety.

[0033] Furthermore, a return spring 120 is provided between the limiting member 110 and the cover plate 200 .

[0034] A return spring 120 is provided, and when the operator releases his foot, the cover plate 200 bounces upward and returns to its original position under the action of the return spring 120 .

[0035] Furthermore, a receiving hole is provided on the limiting member 110 , and when in the first position, the return spring 120 partially extends into the receiving hole; when in the second position, the return spring 120 is completely received in the receiving hole.

[0036] Specifically, since the stopper 110 needs to abut against the cover plate 200, and the return spring 120 is disposed between the stopper 110 and the cover plate 200, when stepping on the cover plate 200, the return spring 120 is easily over-compressed and the stopper 110 is unable to abut against the cover plate 200. Based on this, a receiving hole is provided on the stopper 110 so that the return spring 120 can be compressed into the receiving hole, thereby preventing the return spring 120 from being over-compressed and preventing the stopper 110 from being unable to abut against the cover plate 200.

[0037] Furthermore, the cover plate 200 also includes a side enclosure 220 connected to the main board 210, and a limiting ring 230 extends inward from one end of the side enclosure 220 away from the main board 210, and the limiting ring 230 is located below the limiting member 110. The limiting ring 230 can be abutted against the lower surface of the limiting member 110 to limit the movement of the cover plate 200 in a direction away from the shell 100.

[0038] Specifically, the limiting ring 230 is arranged to abut against the lower surface of the limiting member 110 , so as to limit the cover plate 200 from continuing to bounce upward, thereby preventing the cover plate 200 from falling off the housing 100 under the elastic force of the return spring 120 .

[0039] Furthermore, a guide column 130 is provided on the housing 100 along the height direction, and a notch 231 is formed in the limiting ring 230 . The guide column 130 is located in the notch 231 and can slide relative to the cover plate 200 .

[0040] The guide column 130 and the notch 231 are provided to constrain the up-and-down movement direction of the cover plate 200, thereby preventing the cover plate 200 from shaking laterally when moving up and down, and enhancing its stability.

[0041] Furthermore, the upper surface of the cover plate 200 has a treading area 211 in the middle, and the height of any point on the treading area 211 is equal. The height of the upper surface of the cover plate 200 gradually decreases from the treading area 211 to the outside.

[0042] In the second position, the treading area 211 is flush with the surface of the platform.

[0043] The treading area 211 is for the operator to tread on, and the distance from the treading area 211 to the edge of the cover plate 200 is roughly equal to the distance from the forefoot to the heel of an adult, so the operator can step on the treading area 211 with the forefoot, and the heel of the operator can just step on the platform. Since the treading area 211 and the platform are in the same plane, the forefoot and heel of the operator can just be in the same plane, thereby enhancing the stability and safety of the operator when standing.

[0044] At the same time, the upper surface of the cover plate 200 is configured such that the middle stepping area 211 is higher and the surrounding steps are lower, so that the operator can quickly find the center of the cover plate 200 and step on the center position to squeeze the cover plate 200 downward, which can make the force around the cover plate 200 more uniform, and the cover plate 200 is not easy to shake laterally due to uneven force during the descent.

[0045] Furthermore, the treading area 211 is arranged in a circular shape.

[0046] The treading area 211 is circular, so that no matter from which direction the operator steps on the treading area 211, the heel of the operator can stand on the platform, and the entire sole of the foot is in the same plane, thereby enhancing the standing stability.

[0047] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back...) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0048] In addition, in the present invention, the descriptions such as "first", "second", "one", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of the features. In the description of the present invention, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.
