[0022] A connecting rod frame type pedal water pump comprises: a pump body 13, a pump cover and a piston rod 14, wherein the pump cover is fixedly mounted on the upper part of the pump body 13, one end of the piston rod 14 passes through the center of the pump cover and is arranged inside the pump body 13, and its innovation lies in that it also comprises: a pedal structure frame 23, a pedal rod 10, a foot pedal 8, a connecting rod structure and a gear mechanism, wherein the pedal structure frame 23 comprises a base 17, a support rod 18 is vertically mounted on the base 17, a cross bar 22 is fixedly mounted on the support rod 18, a gear mechanism is mounted on the cross bar 22, pedal rods 10 are mounted on both sides of one end of the gear mechanism, a foot pedal 8 is fixedly mounted on the pedal rod 10, a connecting rod mechanism is radially fixedly mounted on the other end of the gear mechanism, and the connecting rod mechanism is hinged to the piston rod 14.

[0023] Wherein, the pump body is a multi-stage pump body composed of at least one single-stage pump body connected in series.

[0024] The pedal structure frame 23 is in the form of a bicycle frame, and a support rod group 19 is vertically fixedly installed at one end of the base 17 of the pedal structure frame 23. A support seat 12 is installed on the top of the support rod group 19 to achieve stable placement of the pump body 13. The other end of the base 17 is tilted and fixedly installed with a first tilt rod 11.

[0025] A second tilting rod 20 is fixedly mounted on one end of the cross bar 22 on the pedal structure frame 23. In order to facilitate the user to bear force, handles 3 are fixedly mounted on both sides of the top of the second tilting rod 20. A third tilting rod 16 is fixedly mounted on the other end of the cross bar 22. A seat 7 is installed on the top of the third tilting rod 16. The seat 7 is used in conjunction with the handle 3 and the foot pedal 8. Compared with the traditional water pump that needs to stand to pump water, it is more convenient for users to save time and effort when pumping water, and the third tilting rod 16 is fixedly connected to the first tilting rod 11; a fourth tilting rod 21 is fixedly mounted on the cross bar 22, and the other end of the fourth tilting rod 21 is fixedly connected to the second tilting rod 20 to achieve the stability of the pedal structure frame 23.

[0026] The gear mechanism includes a driving gear 9, a driven gear 5 and a transmission chain 6. The central axes of the driving gear 9 and the driven gear 5 are both mounted on the crossbar 22 of the pedal structure frame 23.

The bottom end of the piston rod passes through the pull-out hole and is placed inside the pump body 13. The top end of the piston rod 14 is hinged to the piston connecting rod 15, and a limit block is coaxially arranged at the pull-out hole on the lower surface of the pump cover to ensure that the piston rod 14 moves vertically up and down at a limited position, so that it has good sealing performance and prevents water in the pump from overflowing from the pump cover.

[0029] Working principle:

[0030] When starting work, the user sits on the seat 7, holds the handle 3 and steps on the foot pedal 8, which drives the driving gear 9 to rotate through the transmission chain 6, and then drives the driven gear 5 to rotate. As the driven gear 5 rotates, the position and angle of the connecting rod mechanism also change, thereby driving the piston to move up and down to achieve water pumping.
