Description

Technical Field

[0001] This utility model belongs to the field of foot switches, specifically a foot switch. Background Technology

[0002] A foot switch is a switch that controls the on / off state of a circuit by stepping on it. It is used in control circuits where the hands cannot reach, so as to replace the hands in operation. A simple foot switch is actually a limit switch with a built-in limit switch. When the foot provides a signal, the switch is activated.

[0003] Chinese utility model patent CN217933493U discloses a foot switch, including a base device for support and fixation. Two pedal devices for stepping are symmetrically mounted on the base device. Two rebound devices for automatic reset are symmetrically mounted in the middle of the base device. A top cover plate for sealing is mounted on the base device. The pedal devices and the base device are rotatably connected. The base device includes a base plate, a sealing box is provided on the base plate, two switch bodies are symmetrically mounted inside the sealing box, a toggle plate is provided in front of the switch bodies, a wire outlet is provided at the rear of the sealing box, and a partition is provided in front of the sealing box.

[0004] Regarding the aforementioned technologies, the inventors believe that the following defects exist: the height of the foot pedal switch affects the fatigue intensity of the user's ankle joint. The user will feel particularly tired after raising their foot for a long time. The aforementioned double foot pedal is made by connecting two single foot pedals with a base plate, which increases the overall height, which is not user-friendly, affects the fatigue intensity of the user's ankle joint, and causes great inconvenience.

[0005] To address this issue, those skilled in the art have proposed a foot switch to solve the problems raised in the background art. Utility Model Content

[0006] To address the aforementioned technical problems, this utility model provides a foot switch that solves the problem of excessively high foot pedal height in the prior art, which affects the fatigue strength of the user's ankle joint.

[0007] A foot switch includes a base shell, a rotating shaft rotatably disposed between the left and right inner walls of the base shell, and a pedal mounted on the outside of the rotating shaft. The pedal is provided in two pieces and is symmetrically arranged about the center line of the base shell. A return spring is provided on the inner wall of the base shell, and the two ends of the return spring are respectively connected to the inner bottom wall of the base shell and the lower surface of the pedal.

[0008] A drive seat is fixedly installed on the inner bottom wall of the base shell. A drive button is provided on the side wall of the drive seat. A fixing plate is fixedly installed on the upper side of the drive seat. A through groove is opened on the upper side of the fixing plate. The drive plate is rotatably set in the through groove. A pressing part is provided at the lower end of the drive plate. A drive part is provided on the side wall of the drive plate. One end of the drive part contacts the lower surface of the pedal. The pedal is basically at the same height as the base shell.

[0009] Preferably, an anti-slip strip is fixedly installed on the upper side of the pedal.

[0010] Preferably, pads are fixedly installed at the four corners of the lower surface of the base shell.

[0011] Preferably, the side wall of the base shell is provided with a wire groove, and a protective coil is fixedly installed on the inner side of the wire groove.

[0012] Preferably, four reset springs are provided and they are evenly distributed on the bottom wall of the base shell.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. This utility model adopts an embedded design scheme. In order to ensure a certain pedaling stroke and improve pedaling comfort, the foot needs to press all the way in when triggered. At the same time, the width of the pedal is increased to accommodate the width of the entire foot, thereby improving the comfort of pedaling and reducing the problem of excessively high pedal height affecting the user's ankle joint fatigue.

[0022] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0023] Example 1: As shown in the attached document Figure 1 To be continued Figure 5 As shown: This utility model provides a foot switch, including a base shell 1, a rotating shaft 2 rotatably disposed between the left and right inner walls of the base shell 1, and a pedal 3 installed on the outside of the rotating shaft 2. The pedal 3 is provided in two pieces and is symmetrically arranged about the center line of the base shell 1. A return spring 4 is provided on the inner wall of the base shell 1. The two ends of the return spring 4 are respectively connected to the inner bottom wall of the base shell 1 and the lower surface of the pedal 3. At the same time, the foot position of the pedal 3 is controlled at the front end, so that it is easier to step on and the toes do not need to exert too much force.

[0024] A drive seat 5 is fixedly installed on the inner bottom wall of the base shell 1. A drive button 7 is provided on the side wall of the drive seat 5. A fixing plate 6 is fixedly installed on the upper side of the drive seat 5. A through groove 9 is opened on the upper side of the fixing plate 6. The drive plate 8 is rotatably set in the through groove 9. A pressing part 10 is provided at the lower end of the drive plate 8. A drive part 11 is provided on the side wall of the drive plate 8. One end of the drive part 11 contacts the lower surface of the pedal 3. The pedal 3 is basically at the same height as the base shell 1.

[0025] Preferably, the width of the single pedal 3 can be 130mm, the overall width can be 290mm, and the height can be 20mm.

[0026] As can be seen from the above, when using the device, pressing the pedal 3 compresses the drive part 11 of the drive plate 8, causing the drive plate 8 to rotate. When the drive plate 8 rotates, it causes the compression part 10 to compress the drive button 7, thereby activating the device. After pressing, the device is reset by the return spring 4. This device adopts an embedded design scheme. In order to ensure a certain pedaling stroke and improve pedaling comfort, the pedal position of the foot pedal 3 is controlled at the front end, so pedaling is easier and the toes do not need to exert too much force. When triggering, the foot needs to press all the way in. At the same time, by increasing the width of the pedal 3 to accommodate the width of the entire foot, the comfort of pedaling the pedal 3 is improved, and the problem of the existing foot pedal 3 being too high and affecting the fatigue intensity of the user's ankle joint is reduced.

[0027] Example 2: Based on Example 1, an anti-slip strip 12 is fixedly installed on the upper side of the pedal 3. The anti-slip strip 12 can improve the anti-slip effect during use. Pads 13 are fixedly installed at the four corners of the lower surface of the base shell 1. The pads 13 can support the device. A wire groove 14 is opened on the side wall of the base shell 1. A wire guard coil 15 is fixedly installed on the inner side of the wire groove 14. The wire groove 14 and the wire guard coil 15 can be used for wire management. Four reset springs 4 are provided and they are evenly distributed on the inner bottom wall of the base shell 1.

[0028] As can be seen from the above, the anti-slip strip 12 can improve the anti-slip effect during use, and the cable groove 14 and the cable guard 15 can be used for cable management.
