[0015] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0016] Please refer to Figures 1-6A CNC-machined multi-purpose foot pedal includes a pedal support frame 1 and an electric telescopic rod 2. The electric telescopic rod 2 is fixedly connected to the lower wall of the pedal support frame 1. Two slide bars 3 are fixedly installed on the upper wall of the pedal support frame 1. A pedal structure is slidably connected to the outer wall of the two slide bars 3. The pedal structure includes: a pedal body 4, two sets of pedal grooves 5, two sets of limiting pin holes 6, and two sets of stepped holes 7. The pedal body 4 is slidably connected to the two slide bars 3 through the two sets of pedal grooves 5. The pedal grooves 5 are dovetail grooves. The two sets of limiting pin holes 6 are respectively set as through holes and are opened at both ends of the pedal body 4. A box-shaped storage groove 8 is opened in the pedal support frame 1, and the sliding mechanism is located within the box-shaped storage groove 8. An auxiliary structure is connected, which includes: a storage box 9, two load-bearing slide rails 10, a rotating groove 11, a fixed rotating shaft 12, auxiliary rollers 13, and a foot pedal 14. The storage box 9 is slidably connected to the storage groove 8 of the box body through the load-bearing slide rails 10 on both sides. The rotating groove 11 is opened on the rear wall of the storage box 9. The fixed rotating shaft 12 is fixedly installed in the rotating groove 11. The auxiliary rollers 13 are fitted on the outer wall of the fixed rotating shaft 12. The foot pedal 14 is fixedly installed on the upper end face inside the storage box 9. A limiting structure for fixing the foot pedal structure is connected between the foot pedal structure and the foot pedal support frame 1. A guide structure for connecting the auxiliary structure is connected between the auxiliary structure and the foot pedal support frame 1.

[0017] Please refer to Figure 4 The limiting structure includes: two limiting storage slots 15, two screws 16, two limiting sleeves 17, and two rotating sleeves 18; the two limiting storage slots 15 are respectively opened on the two sides of the pedal support frame 1, the two screws 16 are respectively fixedly installed on the lower wall inside the two limiting storage slots 15, the two limiting sleeves 17 are respectively fitted on the outer wall of the two screws 16, and are respectively threaded to the two screws 16, and the two rotating sleeves 18 are respectively fixedly installed on the outer wall of the two limiting sleeves 17.

[0018] Please refer to Figure 4 The top of each of the two limiting sleeves 17 is provided with an assembly chamfer 19, and the outer wall of each of the two rotating sleeves 18 is provided with a number of anti-slip grooves 20. In use, the assembly chamfer 19 reduces the resistance of the limiting sleeve 17 when it is inserted into the limiting pin hole 6, and the anti-slip grooves 20 on the outer wall increase the friction.

[0019] Please refer to Figure 3 The guide structure includes: two guide grooves 21, two support slides 22 and two sets of guide sliders 23; the two guide grooves 21 are respectively opened on the upper wall of the pedal support frame 1, and the two support slides 22 are respectively connected to the two guide grooves 21 through the two sets of guide sliders 23.

[0020] Please refer to Figure 3Each of the two support slides 22 has a slide rail 24. The thickness of the two slide rails 24 is greater than that of the two load-bearing slide rails 10. When in use, lift the front end of the storage box 9 so that the two load-bearing slide rails 10 rotate slightly in the slide rail 24 and the auxiliary roller 13 contacts the wall of the worktable of the electric telescopic rod 2.

[0021] Please refer to Figure 5 The upper and lower walls of the pedal body 4 are respectively provided with fixing grooves 25. The first anti-slip plate 26 and the second anti-slip plate 27 are respectively fixedly installed in the two fixing grooves 25. The upper wall of the first anti-slip plate 26 is provided with several drainage grooves 28. The second anti-slip plate 27 is made of rubber pad.

[0022] Please refer to Figure 5 Each of the two sets of stepped holes 7 has an anti-clogging block 29 adsorbed in it. When in use, the anti-clogging block 29 prevents processing debris from entering the limit pin hole 6.

[0023] Example 1: In this example, the adaptability of the pedal body 4 to different processing environments is achieved by flipping and switching the pedal body 4, thus solving the limitations of a single anti-slip structure.

[0024] Specifically, when using the pedal support frame 1, it is necessary to switch according to the processing environment: In a humid environment or when coolant splashes, the first anti-slip plate 26 faces upward in the initial state. The operator checks whether the two sets of anti-blocking blocks 29 are inserted into the stepped hole 7 (to prevent debris from entering the limit pin hole 6). Then, the operator holds the rotating sleeve 18 and rotates it around the screw 16, which drives the limit sleeve 17 to rise along the screw. The assembly chamfer 19 at the top of the sleeve reduces the insertion resistance, allowing the limit sleeve to accurately enter the limit pin hole 6 and complete the fixation of the pedal body 4. At this time, the drainage groove 28 on the first anti-slip plate 26 can quickly drain the dripping coolant, preventing water accumulation on the pedal surface and thus preventing slippage. In oily environments or scenarios with a lot of cutting oil: switch to the second anti-slip plate 27 facing upwards, first pull out the anti-blocking block 29, rotate the rotating sleeve 18 in the opposite direction to disengage the limiting sleeve 17 from the limiting pin hole 6, and release the fixation. Then, pull out the pedal body 4 along the slide bar 3 through the pedal slide groove 5, flip it over, reinsert the slide bar 3, and then fix it with the limiting sleeve 17. The rubber material of the second anti-slip plate 27 can enhance the friction with the sole of the shoe and resist the risk of slippage caused by oily substances.

[0025] Example 2: In this example, the height of the electric telescopic rod 2 is adjusted to adapt to different working conditions. Combined with the auxiliary structure, it has both step and storage functions, which improves the convenience of operation and space utilization. It is especially suitable for the frequent up and down operation of large CNC equipment.

[0026] Specifically, when the CNC equipment worktable is raised and the operator needs to raise the pedal height: the electric telescopic rod 2 is activated, which drives the pedal support frame 1 to rise to the appropriate height. During the rising process, the storage box 9 remains relatively stationary due to gravity, causing the support slide 22 to slide along the guide groove 21 via the guide slider 23, thus preventing the storage box 9 from colliding with the pedal support frame 1. After the electric telescopic rod stops, grasp the front end of the storage box 9 and drag it outwards. The two load-bearing slide rails 10 slide along the slide rails 24 of the support slide 22 (the slide rail thickness is greater than the slide rail to allow for rotational allowance, making it easy to lift one end of the storage box 9 until the foot pedal 14 is fully exposed). At this time, the operator can step on the foot pedal 14 to climb onto the pedal body 4 to complete the height transition. If tools (such as wrenches or gauges) need to be stored, simply place the tools into the storage box 9. When closing, drag the storage box in the opposite direction to retract it into the storage slot 8. If the dragging resistance is too large, the front end of the storage box can be lifted to allow the auxiliary roller 13 to rotate around the fixed pivot 12 and contact the worktable surface. The roller rolling reduces friction, making storage easy. Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
