Description

Technical Field

[0001] This utility model relates to the field of foot pedals, and in particular to folding foot pedals. Background Technology

[0002] A high-pressure air pump refers to an air pump whose walls and piston can withstand extremely high pressure, allowing it to pump ultra-high-pressure gas into objects. Ultra-high-pressure air pumps are generally equipped with a foot pedal for users to hold the pump in place. Current related foot pedal devices, such as the foldable foot pedal for ultra-high-pressure air pumps disclosed in patent application number 200910034390.3, utilize springs to open and close two pedals. However, the springs are easily corroded by prolonged exposure to rain and other external substances, affecting their lifespan. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a folding foot pedal, which uses gears and rack segments to drive the pedal to swing. It is very convenient to store and unfold. The spring and slide rod are located in the sliding hole, which can reduce external corrosion and significantly improve its service life.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a folding foot pedal, including a base and two pedals, the two pedals being distributed left and right, the inner ends of the pedals being hinged to the lower part of the base, and the top of the base being provided with mounting holes, characterized in that...

[0005] The base is vertically provided with a sliding hole, and a sliding rod is slidably fitted in the sliding hole. A spring is provided between the sliding rod and the sliding hole. The spring pushes the sliding rod to slide upward. The base is provided with a locking member to prevent the sliding rod from sliding upward. The lower section of the sliding rod is provided with rack sections on both sides.

[0006] The lower side wall of the sliding hole is provided with a side window corresponding to the inner end of the pedal. The pedal is provided with a gear with the hinge shaft as the axis. The gear passes through the side window and meshes with the rack section.

[0007] When the slide bar slides downwards, it drives the outer end of the pedal to close upwards through the gear and rack segments;

[0008] When the slide bar slides upward, it drives the outer end of the pedal to swing downward and touch the ground through the gear and rack segments.

[0009] In this design, during the up-and-down sliding of the slide bar, the rack segment drives the gear to rotate, thereby causing the pedal to swing. When the slide bar slides down, the gear and rack segment drive the outer end of the pedal to close upward. At this time, the locking device locks the slide bar to prevent it from sliding upward, thus preventing the pedal from swinging downward automatically. When the locking device is released, when the slide bar slides up, the gear and rack segment drive the outer end of the pedal to swing downward and touch the ground.

[0010] Preferably, the locking element is a threaded plug, and the upper end of the sliding hole is threadedly fitted to the threaded plug. By rotating the threaded plug, the upper limit of the upward sliding of the idle slide rod can be achieved. If the slide rod needs to slide upward, the threaded plug can be rotated to a higher position to allow more space for the slide rod to slide within the sliding hole. If the upward sliding of the slide rod is restricted, the threaded plug can be rotated downward to block the slide rod.

[0011] Preferably, the base has side grooves on both sides, the inner end of the pedal is hinged to the side groove, and the side window is located on the side wall of the side groove. This makes it easier to store the pedal in the side groove.

[0012] Preferably, the spring is located at the bottom of the sliding hole, and the upper end of the spring abuts against the lower end of the sliding rod. This can provide more thrust.

[0013] Preferably, the lower inner wall of the sliding hole has a planar structure corresponding to the rack segment. This prevents the slide rod from rotating within the sliding hole, allowing for a more stable engagement between the rack segment and the gear.

[0014] The beneficial effects of this utility model are:

[0015] This design uses gears and racks to drive the pedal swing, making it very convenient to store and unfold. The spring and slide bar are located inside the sliding hole, which can reduce external corrosion and significantly improve its service life. Attached Figure Description

[0020] To enhance understanding of this utility model, it will be described in further detail below with reference to the accompanying drawings and embodiments. These embodiments are only used to explain this utility model and do not limit the scope of protection of this utility model.

[0021] Example

[0022] like Figure 1 As shown, the folding foot pedal includes a base 1 and two pedals 2, which are distributed left and right. The inner ends of the pedals 2 are respectively hinged to the lower part of the base 1. Figure 2 As shown, the base 1 has a mounting hole at its top and a vertical sliding hole 3. A sliding rod 4 is slidably fitted inside the sliding hole 3. A spring 6 is provided between the sliding rod 4 and the sliding hole 3. The spring 6 pushes the sliding rod 4 to slide upward. The base 1 is provided with a locking member 5 to prevent the sliding rod 4 from sliding upward. Rack segments 10 are provided on both sides of the lower section of the sliding rod 4. A side window 7 is provided on the lower side wall of the sliding hole 3 corresponding to the inner end of the pedal 2. A gear 9 is provided on the pedal 2 with the hinge axis as its axis. The gear 9 passes through the side window 7 and meshes with the rack segment 10. When the sliding rod 4 slides downward, the gear 9 and the rack segment 10 drive the outer end of the pedal 2 to close upward.

[0023] When the slide bar 4 slides upward, it drives the outer end of the pedal 2 to swing downward and touch the ground through the gear 9 and the rack segment 10.

[0024] In this design, during the up-and-down sliding of the slide bar 4, the gear 9 is rotated by the rack segment 10, which causes the pedal 2 to swing. When the slide bar 4 slides downward, the gear 9 and rack segment 10 cause the outer end of the pedal 2 to close upward. At this time, the locking member 5 locks the state of the slide bar 4 to prevent it from sliding upward, thus preventing the pedal 2 from swinging downward automatically. When the locking member 5 is released, when the slide bar 4 slides upward, the gear 9 and rack segment 10 cause the outer end of the pedal 2 to swing downward and touch the ground.

[0025] The locking element 5 is a threaded plug, and the upper end of the sliding hole 3 is threadedly fitted to the threaded plug. By rotating the threaded plug, the upper limit of the upward sliding of the idle sliding rod 4 can be achieved. If the sliding rod 4 needs to slide upward, the threaded plug can be rotated to a higher position to leave more room for the sliding rod 4 to slide within the sliding hole 3. If the upward sliding of the sliding rod 4 is restricted, the threaded plug can be rotated downward to block the sliding rod 4.

[0026] The base 1 has side grooves 8 on both sides, and the inner end of the pedal 2 is hinged to the side groove 8. The side window 7 is located on the side wall of the side groove 8. This makes it easier to store the pedal 2 inside the side groove 8.

[0027] The spring 6 is located at the bottom of the sliding hole 3, and the upper end of the spring 6 abuts against the lower end of the sliding rod 4. This allows for a greater thrust.

[0028] The lower inner wall of the sliding hole 3 has a planar structure corresponding to the rack segment 10. This prevents the slide rod 4 from rotating within the sliding hole 3, allowing for a more stable engagement between the rack segment 10 and the gear 9. Specifically, the lower section of the slide rod 4 uses a quadrangular prism structure, while the upper section uses a cylindrical structure.

[0029] It is important to note that, such as Figure 2 As shown, in order to facilitate better downward contact between the pedal 2 and the ground, a hinge arm can be provided at the inner end of the pedal, and the end of the hinge arm is hinged to the side groove 8, that is, the hinge point is offset from the pedal 2.

[0030] The lower end of the slide bar 4 is provided with a receiving hole, and the upper end of the spring 6 is located inside the receiving hole.

[0031] The beneficial effects of this utility model are:

[0032] This design uses gear 9 and rack segment 10 to drive pedal 2 to swing, making it very convenient to store and unfold. Spring 6 and slide bar 4 are located inside slide hole 3, which can reduce external corrosion, make the structure more compact, and significantly improve its service life.

[0033] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0034] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
