Abstract
The utility model discloses a two-barrel folding pedal inflator, composed of two air cylinders, exhaust pipe nozzles, a lower coupling nut, a base, a floating lever rod mechanism and a hand supporting mechanism. Air cylinder pistons are driven by the floating lever rod mechanism to move up and down. The hand supporting mechanism keeps the floating lever rod mechanism normally working. The utility model has the advantages of labor saving, high efficiency, convenient portability, peculiar and simple design of structure, small size, and capability of being folded for storage while not in use.
Description
The utility model belongs to foot-operated air pump and makes the field.
Prior art in the utility model prior art field is: CN2073039U, " pocket foot-operated air pump ", this pump is made up of bitubular lid, foot-operated lid, valve gap, spring, bottom, ball valve, rubber band, fixing frame, working beam, double shell.By the bitubular and the integrant double shell of gas storage pump side by side.End face, the circumferential surface inboard of bitubular lid have convex tendon to be beneficial to ventilation cleaning, and the employing ball valve can be laborsaving, and spring is contained in and helps maintenance in the bitubular, and double-barrel structure improves charging efficiency greatly.
Purpose of design of the present utility model is: adopt two cylinders, floating lever rod mechanism and hold up support structure to combine to constitute the foldable type foot-propelled and hold up and support the lever pump.
Design proposal of the present utility model is: bitubular Folding pedal pump, it comprises two cylinders 8, outlet pipe chews 9, following coupling nut 10, base 14 and foot-operated 16, bracket 17 is connected with base 14 by bearing pin and base 14 can rotate around bearing pin, column plate 4 is fixed on the bracket 17, the upper end of column plate 4 is connected with floating lever rod 2 by bearing pin 3, there is extension spring hook 1 rear end of floating lever rod 2, an end and the extension spring hook 1 of hanging spring 6 articulate, the other end is hung spring with the bottom that is fixed on column plate 4 and is articulated, the front portion of floating lever rod 2 is connected with the upper end portion of the piston rod of two cylinders 8 by bearing pin 7, the bottom of two cylinders 8 is connected with bracket 17 by connecting pivot pin 11 under coupling nut 10 reaches down, the front end of floating lever rod 2 is connected by the upper end of bearing pin with foot-operated connecting plate 15, the lower end of foot-operated connecting plate 15 is connected with foot-operated 16 by bearing pin, holds up an end of support 5 to be connected with the top of column plate 4, the other end is connected with foot-operated connecting plate 15.An one-way valve 13 is equipped with at the center of the connection screwed pipe 12 at the bottom of the cylinder on the bottom of cap.2～4 inlet holes are arranged at the bottom of cap at the bottom of the cylinder of cylinder, and the blocking valve 18 of an air inlet is housed in the inlet hole.Its working principle is: pin steps foot-operated 16 downwards and drives foot-operated connecting plate 15, floating lever rod 2 moves downward, extension spring 6 is opened, thereby the piston of cylinder 8 is moved downward, and gas is chewed 9 through one-way valve 13, outlet pipe enter and filled adhesive tape, when pin makes progress, under the effect of extension spring 6, floating lever rod 2, foot-operated connecting plate 15 reset, and the piston of cylinder moves upward, air is in blocking valve 18 enters the tube of cylinder 8, for next time action, so circulation, up to adhesive tape gas is filled full till.
The utility model adopts two cylinders, floating lever rod mechanism to combine with holding up support structure, has that structural design uniqueness, body are little, simple, dexterous, a dynamic inflation, laborsaving and advantage that charging efficiency is high, and the time spent foldable for storage is not easy to carry.Be applicable to the inflation of adhesive tapes such as motorcycle, bicycle, handcart.
Description of drawings:
Fig. 1 is a main TV structure schematic representation of the present utility model.
Fig. 2 is a side-looking structural representation of the present utility model.
1 pair of the utility model is done with narration in conjunction with the accompanying drawings.
Bracket 17 is connected with base 14 by bearing pin and base 14 can overturn around bearing pin, and is shaped at base 14 and bumps the hole of bead, and when folding, bumping on the base 14 bumping that pearl breaks away from and upwards upset on the hole of bead and the bracket 17; Column plate 4 is fixed on the bracket 17, the upper end of column plate 4 is connected with floating lever rod 2 by bearing pin 6, there is extension spring hook 1 rear end of floating lever rod 2, an end of hanging spring 6 articulates with hook 1, the other end is connected with the bottom extension spring hook that is fixed on column plate 4, the extension spring hook of bottom divides 1～3 grade, the front portion of floating lever rod 2 is connected with the upper end portion of the piston rod of two cylinders 8 by bearing pin 7, the bottom of two cylinders 8 is connected with bracket 17 by connecting pivot pin 11 under coupling nut 10 reaches down, the front end of floating lever rod 2 is connected by the upper end of bearing pin with foot-operated connecting plate 15, the lower end of foot-operated connecting plate 15 is connected with foot-operated 16 by bearing pin, holds up an end of support 5 and the upper pin of column plate 4 to connect, the other end and foot-operated connecting plate 15 pins connect.For the reliability that guarantees to inflate, to (give vent to anger) center of the connection screwed pipe 12 of one-way valve 13 screw thread spinnings on the bottom of cap at the bottom of the cylinder, in order to guarantee cylinder 8 air inlet abundances, be shaped on 2～4 inlet holes in the bottom of the cylinder cap of cylinder, the blocking valve 18 of an air inlet is housed in the inlet hole.Cylinder 8 and outlet pipe are chewed 9 and are belonged to prior art, so be not described herein at this.
