[0030] As shown Figure 1 - Figure 3 A foot switch according to the present disclosure includes a base body 10, a pedal 20 and a switch assembly 30 provided on the base body 10. Circuit elements are provided inside the base body 10;

[0031] The pedal 20 is rotatably connected to the base body 10;

[0032] The switch assembly 30 includes a push rod 301, an elastic member 302 and a button member. The button member is provided inside the base body 10 and is electrically connected to the circuit elements;

[0033] One end of the elastic member 302 is connected to the surface of the button member. The other end of the elastic member 302 is partially sleeved on one end of the push rod 301 and embedded inside the base body 10. The push rod 301 has a structure similar to a stepped shape. The cross-sectional area of the part of the push rod 301 sleeved with the elastic member 302 is smaller than the cross-sectional area of the part of the push rod 301 not sleeved with the elastic member 302;

[0034] The other end of the push rod 301 protrudes outside the base body 10 and abuts against the pedal 20. By pushing the push rod 301 through the pedal 20, the push rod 301 is made to move towards the button member. Due to the elastic force of the elastic member 302, the push rod 301 has a tendency to move away from the base body 10;

[0035] By stepping on the pedal 20 with the foot, the pedal 20 rotates downward relative to the base body 10 and pushes the push rod 301, making the push rod 301 move towards the button member. Further, the push rod 301 compresses the elastic member 302 and the end of the push rod 301 embedded in the base body 10 presses against the button member. When the foot releases the pedal 20, due to the elastic force of the elastic member 302, the push rod 301 moves away from the base body 10, further releasing the button member, so that both the pedal 20 and the push rod 301 rebound to the initial position;

[0036] In the above structure, one end of the elastic member 302 is connected to the surface of the button member, and the other end of the elastic member 302 is partially sleeved on one end of the push rod 301 and embedded inside the base body 10. Compared with the setting method of the foot switch with the spring placed outside and without any protection, it can effectively protect the elastic member 302 from being polluted by the external environment such as dust and oil stains, which helps to extend the service life of the elastic member 302 and reduce wear and aging caused by external factors. And the elastic member 302 is embedded inside the base body 10, reducing the frequency of cleaning and maintenance and eliminating the need for frequent disassembly or cleaning.

[0037] Further, in this embodiment, the foot switch further includes a protective cover body 40, and the protective cover body 40 is connected to the base body 10. Specifically, both ends of the protective cover body 40 are respectively connected to both sides of the base body 10, so that the protective cover body 40 can wrap above the base body 10 and the pedal 20, and can block dust, oil stains, etc. from falling and polluting the base body 10 and the pedal 20.

[0038] Further, in this embodiment, both sides of the pedal 20 are respectively connected to both sides of the seat body 10 through a rotating hinge 50; specifically, the pedal 20 is rotatably connected to the upper end of the seat body 10 close to it, so that the pedal 20 can rotate from the upper end of the seat body 10 towards the bottom end of the seat body 10, that is, the pedal 20 can rotate downward and gradually approach the bottom end of the seat body 10.

[0039] Further, in this embodiment, the pedal 20 forms an included angle A with the seat body 10 through the rotation of the rotating hinge 50, and A satisfies: 0 < A ≤ 90°.

[0040] Further, in this embodiment, the pedal 20 has an extension part 201 extending downward, and the extension part 201 abuts against one end of the push rod 301 exposed outside the seat body 10; that is, when the pedal 20 rotates downward, the extension part 201 presses against one end of the push rod 301 exposed outside the seat body 10, thereby pushing the push rod 301 to move towards the seat body 10.

[0041] Further, in this embodiment, the upper surface of the pedal 20 is provided with a convex structure 202, and a plurality of convex structures 202 are arranged at intervals along the length direction on the upper surface of the pedal 20; the convex structure 202 can be a strip-shaped structure, and a plurality of strip-shaped convex structures 202 are arranged at intervals along the length direction on the upper surface of the pedal 20;

[0042] The presence of the convex structure 202 can increase the friction between the foot and the pedal 20 when stepping on the pedal 20, avoiding unsuccessful stepping due to sliding.

[0043] Further, in this embodiment, the elastic member 302 is a spring, and the elastic force of the spring makes the push rod 301 have a tendency to move away from the seat body 10.

[0044] The present disclosure also proposes a pressing machine, including the foot switch as described above, and further including a pressing machine main body, the pressing machine main body is electrically connected to the foot switch; the opening and closing of the pressing machine main body are controlled by the foot switch, and the structure of the above foot switch can reduce the wear and aging caused by the external environment, thereby extending the service life of the foot switch, which helps to reduce the occurrence of faults of the pressing machine main body and reduce the maintenance cost and downtime.

[0045] The working process of a foot switch and a pressing machine according to this embodiment will be fully described below in combination with the above content.

[0046] A foot switch includes a base body 10, a pedal 20 and a switch assembly 30 provided on the base body 10. Circuit elements are provided inside the base body 10. The pedal 20 is rotatably connected to the base body 10. The switch assembly 30 includes a push rod 301, an elastic member 302 and a button component. The button component is provided inside the base body 10 and is electrically connected to the circuit elements. One end of the elastic member 302 is connected to the surface of the button component, and the other end of the elastic member 302 is partially sleeved on one end of the push rod 301 and embedded inside the base body 10. The other end of the push rod 301 protrudes outside the base body 10 and abuts against the pedal 20. By stepping on the pedal 20 with the foot, the pedal 20 rotates downward relative to the base body 10 and pushes the push rod 301, causing the push rod 301 to move towards the button component. Further, the push rod 301 compresses the elastic member 302 and the end of the push rod 301 embedded inside the base body 10 presses against the button component. When the foot releases the pedal 20, the elastic force of the elastic member 302 causes the push rod 301 to move away from the base body 10, thereby releasing the button component and causing both the pedal 20 and the push rod 301 to rebound to their initial positions. Compared with the setting method of the foot switch with the spring externally placed and without any protection, the structure of the above foot switch can effectively protect the elastic member 302 from being polluted by the external environment such as dust and oil, which helps to extend the service life of the elastic member 302 and reduce wear and aging caused by external factors. And the elastic member 302 is embedded inside the base body 10, reducing the frequency of cleaning and maintenance and eliminating the need for frequent disassembly or cleaning.

[0047] A press includes the above foot switch and further includes a press main body which is electrically connected to the foot switch. In the above manner, when the foot steps on the pedal 20, the button component starts the press main body, and when the foot releases the pedal 20, the button component closes the press main body. Due to the structure of the above foot switch, the situation of wear and aging caused by the external environment can be reduced, thereby extending the service life of the foot switch, which helps to reduce the occurrence of faults in the press main body and lower the maintenance cost and downtime.
