Description

Technical Field

[0001] The utility model relates to a folding foot pedal for a pump, mainly belonging to the field of pumps. Background Art

[0002] A high-pressure pump refers to a pump whose cylinder wall, piston, etc. can withstand extremely high pressures and can inject ultra-high-pressure gas into the object to be inflated. Compared with an ordinary pump, a high-pressure pump has an ultra-high-pressure tank. The air inlet of the ultra-high-pressure tank is a one-way intake piston. When the pump is inflated, the piston opens, and the air in the pump enters the ultra-high-pressure tank. When the pump is lifted to inhale air, the piston closes. High pressure is formed in the ultra-high-pressure tank to inflate the object to be inflated. Generally, the cylinder body of a high-pressure pump is equipped with a foot pedal device to facilitate the user to step on the foot pedal to fix the pump when in use.

[0003] The patent document with the publication number CN216665851U discloses a folding foot pedal for a high-pressure pump, which can realize automatic folding of the pedal. However, there is a drawback in actual use, that is, the pedal always tends to be retracted. As long as one foot is lifted, the corresponding pedal will fold. Since there is no fiber on both sides, the other pedal will drive the base to tilt to the other side, and it is necessary to press down the two pedals again when using it again. Content of the Utility Model

[0004] In view of the above deficiencies of the prior art, the utility model provides a folding foot pedal for a pump, which can better switch between the flat state and the retracted state by using the elastic force of a spring, and maintain these two states, making it more convenient to use.

[0005] A folding foot pedal for a pump includes a base and two foot pedals. An installation hole is provided at the upper end of the base;

[0006] A side cavity is provided at the lower part of the base;

[0007] The inner ends of the two foot pedals are hinged to the lower part of one side of the side cavity. A force arm is vertically arranged at the inner end of the foot pedal. One end of the force arm is connected to a spring, and the other end of the spring is connected to the upper part of the other side of the side cavity. The spring pushes the force arm to swing towards the upper or lower part of the side cavity.

[0008] Since the other end of the spring is hinged to the upper part of the other side of the side cavity, and the foot pedal is hinged to the lower part of one side of the side cavity, theoretically, when the force arm swings upward or horizontally (i.e., the state where the foot pedal is flat or retracted upward close to the side wall of the base), the pressure on the spring is the smallest. A greater pressure will be received during the process of switching between the two states. That is, driven by the spring, the state of the pedal is more inclined to be flat or retracted upward, and more inclined to maintain these two states. The pedal can be used normally when it is flat, and the pedal can be retracted upward for storage.

[0009] Preferably, both ends of the spring are hingedly arranged on the force arm and the side cavity respectively. This makes it more convenient for the spring to switch directions between the two states.

[0010] Preferably, the side cavity is respectively provided with connecting seats corresponding to the spring, and the connecting seats are provided with through holes for the ends of the spring to pass through. This facilitates the hinging of the spring.

[0011] Preferably, the end of the force arm is provided with a through hole for the end of the spring to pass through. This facilitates the hinging of the spring.

[0012] Preferably, the bottom of the side cavity is provided with a bottom plate, and notches for the foot pedal to be laid flat are provided on both sides of the bottom plate. This facilitates the swinging of the pedal.

[0013] Preferably, when the bottom plate is laid flat, the inner end of the bottom plate abuts against the notch. This facilitates angle limitation of the pedal when it swings.

[0014] Preferably, the upper surface of the foot pedal is provided with an anti-slip layer. This improves the friction force.

[0015] Preferably, the anti-slip layer is made of rubber material. It has a relatively large friction force and is more durable at the same time.

[0016] The beneficial effects of the present utility model are as follows:

[0017] This solution utilizes the elastic force of the spring, can better switch between the laid-flat and folded states, and maintain these two states, making it more convenient to use. Description of the Drawings

[0024] The following will clearly and completely describe the technical solutions in the present utility model in conjunction with the accompanying drawings. Obviously, the described embodiments are only the preferred embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present utility model without creative work belong to the scope of protection of the present utility model.

[0025] Embodiment

[0026] As Figure 1 shown, the embodiment of the present utility model includes a base 1 and two foot pedals 3. An installation hole 2 is provided at the upper end of the base 1; a side cavity 9 is provided at the lower part of the base 1; the inner ends of the two foot pedals 3 are hinged to the lower part of one side of the side cavity 9. A lever arm 4 is vertically provided at the inner end of the foot pedal 3. One end of the lever arm 4 is connected to a spring 7, and the other end of the spring 7 is connected to the upper part of the other side of the side cavity 9. The spring 7 pushes the lever arm 4 to swing upward or downward in the side cavity 9.

[0027] Combined with Figure 2 and Figure 4 shown, since the other end of the spring 7 is hinged to the upper part of the other side of the side cavity 9 and the foot pedal 3 is hinged to the lower part of one side of the side cavity 9, theoretically when the lever arm 4 swings upward or horizontally (that is, the state where the foot pedal 3 is laid flat or folded upward close to the side wall of the base 1), the pressure on the spring 7 is the smallest. A greater pressure will be received during the process of switching between the two states. That is, driven by the spring 7, the state of the pedal is more inclined to be laid flat or folded upward, and more inclined to maintain these two states. The pedal can be used normally when it is laid flat, and the pedal is folded upward for storage.

[0028] Combined with Figure 3 shown, both ends of the spring 7 are respectively hinged to the lever arm 4 and the side cavity 9. It is more convenient for the spring 7 to switch directions between the two states.

[0029] The side cavity 9 is respectively provided with a connecting seat 8 corresponding to the spring 7. The connecting seat 8 is provided with a through hole for the end of the spring 7 to pass through. Facilitate the hinging of the spring 7.

[0030] The end of the lever arm 4 is provided with a through hole for the end of the spring 7 to pass through. Facilitate the hinging of the spring 7. Figure 1 The hole for the spring 7 to be hinged on the lever arm 4 is different from that in other figures, but it does not affect the principle of realizing its hinging. Both methods can be realized.

[0031] A bottom plate 5 is provided at the bottom of the side cavity 9, and notches 6 for placing the footrest 3 flat are provided on both sides of the bottom plate 5. This facilitates the swinging of the pedal.

[0032] When the bottom plate 5 is placed flat, the inner end of the bottom plate 5 abuts against the notch 6. This facilitates angle limitation of the pedal when it swings.

[0033] An anti-slip layer is provided on the upper surface of the footrest 3. This increases the friction.

[0034] The anti-slip layer is made of rubber material. It has a relatively large friction and is more durable at the same time.

[0035] The beneficial effects of the present utility model are as follows:

[0036] This solution utilizes the elastic force of the spring 7 to better switch between the flat and retracted states and maintain these two states, making it more convenient to use.

[0037] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
