Abstract
The utility model discloses an inflator comprising an inflator body, an air pipe, a piston, a piston rod and a handle. The inflator body is vertically arranged, the piston arranged in the inflator body can move up and down, the piston rod is connected with the piston, and the handle is connected with the piston rod. A supporting barrel positioned outside the inflator body is fixedly sleeved at the lower end of the inflator body. A through hole is reserved on the barrel wall of the supporting barrel, so that a pipe-accommodating cavity for accommodating the air pipe is formed between the supporting barrel and the inflator body. A seal cap for sealing the pipe-accommodating cavity is further arranged on the supporting barrel. The problem that existing inflators are not easy to carry due to large size is solved.
Description
Technical field
The utility model relates to a kind of articles for daily use, specifically a kind of pump.
Background technique
On market, common pump mainly is divided into three major types, but the small-sized pump of foot-operated large-scale pump, hand-held inflator and foot pedal.Pedal tyre pump has bulky and don't holds portative shortcoming; The hand-held type miniature pump easily carries because volume is little, but has or not fulcrum, and the application of force is difficult for and narrow-minded shortcoming; Obviously but the small-sized pump of foot pedal has the advantage of said two devices concurrently, collects conveniently, and volume is little and have fulcrum, makes the easy application of force, but both hypotelorism makes the application of force be difficult for, and can't inflate fast.And the purpose of this utility model is to overcome the deficiencies in the prior art part, and a kind of simple in structure, portable, pump that efficient is high is provided.
The model utility content
The utility model purpose is: for the problems referred to above, a kind of extension type convenient inflator is provided, is intended to overcome existing large-scale pump because of bulky and don't hold portative shortcoming, overcome simultaneously existing small-sized pump little because of volume, without fulcrum, and the application of force is difficult for and narrow-minded shortcoming.
The technical solution of the utility model is: described pump, comprise vertical layout inflator stack shell, tracheae, be positioned at described stack shell and piston, the piston rod that is connected with described piston that can slide up and down and the handle that is connected with piston rod, the lower end fixed cover of described inflator stack shell is provided with and is positioned at the outer supporting drum of this inflator stack shell, thereby offer a through hole on the barrel of described supporting drum and form an appearance tube chamber for accommodating described tracheae between supporting drum and inflator stack shell, also be provided be used to the capping of sealing described appearance tube chamber on supporting drum.
Described piston rod is the upper, middle and lower segment shrinking structure.
Described handle is provided be used to controlling the flexible button of described piston rod.
The bottom of described supporting drum is provided with the pedal that can radially extract out.
The open-topped of described inflator stack shell also detachably is provided with the air cylinder cover that seals this opening, and described piston rod passes this air cylinder cover and is connected with described piston.
The utility model has the advantages that: pump of the present utility model has overcome existing pump because of bulky and don't hold portative shortcoming, overcome simultaneously portable pump little because of volume, without fulcrum, and the application of force is difficult for and narrow-minded shortcoming, meets the new concept of national energy-saving environmental protection.Adopted the structure of the pull-rod type of similar trunk, effectively shunk the pump bar, compared with pedal tyre pump, volume is little, is easy to carry.Add its stable structure, compare with the hand-held type miniature pump, strong fulcrum is provided, and the application of force is more convenient, inflates efficient thereby improved.Have good value for applications.
Description of drawings
Below in conjunction with the drawings and specific embodiments, the utility model is described further:
Fig. 1 is the structural representation of pump in the utility model embodiment;
Fig. 2 is the partial structurtes schematic diagram of pump in the utility model embodiment;
Wherein: the 1-handle, the 2-button, the 3-piston rod, the 4-air cylinder cover, 5-inflator stack shell, the 6-supporting drum, 7-holds tube chamber, 8-capping, 9-pedal, 10-tracheae, 11-piston.
Embodiment
As shown in Figure 1, the pump of the present embodiment, comprise inflator stack shell 5, tracheae 10, piston 11, piston rod 3 and handle 1, wherein: inflator stack shell 5 is vertically arranged, piston 11 is positioned at stack shell inside and can slides up and down, piston rod 3 one ends are connected with described piston 11, and the other end is connected with described handle 1, and tracheae 10 is used for to tire output gas.
Replacing for the ease of the piston 11 in inflator stack shell 5, the present embodiment has also adopted following structure: the open-topped of inflator stack shell 5, and the top of inflator stack shell 5 removably be equipped with the sealing its open-topped air cylinder cover 4, described piston rod 3 passes this air cylinder cover 4 and is connected with described piston 11.
In the present embodiment, the lower end of described inflator stack shell 5 is arranged with and is positioned at the outer supporting drum 6 of this inflator stack shell 5, and this supporting drum 6 fixes with inflator stack shell 5.Thereby offer a through hole on the barrel of described supporting drum 6 and form an appearance tube chamber 7 for accommodating described tracheae 10 between supporting drum 6 and inflator stack shell 5, also be provided with on supporting drum 6 be used to the capping 8 of sealing described appearance tube chamber 7.When this pump does not use, can be with tracheae 10(flexible member) rolling gets up to be placed in described appearance tube chamber 7, then cover capping 8, easy to carry and store; When this pump is worked, open capping 8, take out the tracheae 10 that holds in tube chamber 7 and get final product, very convenient.
As shown in Figure 2, in the present embodiment, described piston rod 3 adopts the upper, middle and lower segment adjustable structure, and handle 1 is provided be used to controlling the flexible button 2 of described piston rod 3, and the umbrella rod that its structure is just used usually as us is not described further at this.When this pump does not use, first press the button 2, then axial pushing piston bar 3 is made its shortening, thus easy to carry and store; When this pump is worked, then press the button 2, twitch piston rod 3 its elongation is got final product, very convenient.
In addition, when preventing that people from using this pump to inflate, pump bottom support point slides with respect to ground, and this example also is provided with pedal 9 in the bottom of described supporting drum 6, and when not using, this pedal 9 can radially insert supporting drum 6 inside; During use, this pedal 9 can be with radially extracting out in supporting drum 6.
Certainly, above-described embodiment only is explanation technical conceive of the present utility model and characteristics, and its purpose is to allow people can understand content of the present utility model and implement according to this, can not limit protection domain of the present utility model with this.All equivalent transformation or modifications of doing according to the Spirit Essence of the utility model main technical schemes are within all should being encompassed in protection domain of the present utility model.
