Description
Technical field
The utility model relates to the air output device technical field, particularly relates to a kind of novel pump.
Background technique
As everyone knows, pump is a kind of in order to inject or to replenish various tires and some ball required air, is widely used in various technical fields; Existing pump comprises cylindrical shell and holding rod, and the below of holding rod is provided with piston rod, and the set inside of cylindrical shell has piston; The below of piston rod is passed cylindrical shell and is connected with piston in the cylindrical shell; Barrel wall is provided with air outlet hole, and in the cylindrical shell outer installment connecting tube that communicates with air outlet hole is arranged, and the end of connecting tube is provided with fixing head; This pump in use finds, fixing head with after tire is communicated with, is inputed to tire through the action holding rod with air; After input air; Gas in the tire can oppositely input in the cylindrical shell once more, and is very inconvenient, and when secondary input air to tire; The anti-air that inputs in the cylindrical shell is input in the tire once more in the part tire, and working efficiency is low relatively.
The model utility content
For solving the problems of the technologies described above, it is a kind of after air is inputed to tire that the utility model provides, and prevents counter the inputing in the cylindrical shell of air in the tire, thus easy-to-operat and increase the novel pump of working efficiency.
The novel pump of the utility model comprises cylindrical shell and holding rod, and the below of holding rod is provided with piston rod; The set inside of cylindrical shell has piston, and the below of piston rod is passed cylindrical shell and is connected with piston in the cylindrical shell, and barrel wall is provided with air outlet hole; And the connecting tube that communicates with air outlet hole arranged in the cylindrical shell outer installment; The end of connecting tube is provided with fixing head, also is provided with the fixedly plug and the backflush device that have pore in the said cylindrical shell, and said cylindrical shell top is provided with inlet hole; Said fixedly plug is between piston and air outlet hole; And said fixedly plug is fixed in the cylindrical shell, and said backflush device is positioned at the pore of fixing plug, and said backflush device links together through first spring and cylinder inboard wall.
The novel pump of the utility model also is provided with seal ring between said piston and the fixing plug, and when depressing holding rod, holding rod drives piston, and the bottom of piston is passed seal ring and driven seal ring.
The novel pump of the utility model, said piston and said second spring that fixedly also is provided with between the plug.
The novel pump of the utility model, said inlet hole are 4.
Compared with prior art the beneficial effect of the utility model is: in cylindrical shell, also be provided with the fixedly plug and the backflush device that have pore; The cylindrical shell top is provided with inlet hole; Fixing plug is between piston and air outlet hole; And fixing plug is fixed in the cylindrical shell, and backflush device is positioned at the pore of fixing plug, and backflush device links together through first spring and cylinder inboard wall; Like this, in use, depress holding rod drive piston and move downward; At this moment, through air-flow backflush device is extruded in the pore of fixing plug, air flows to the air outlet hole place in the pore of fixing plug; After mentioning holding rod, because the effect of first spring, backflush device is back in the pore of fixing plug again; Block pore, thereby prevented counter the inputing in the cylindrical shell of air in the tire, easy-to-operat also increases working efficiency.
Description of drawings
Fig. 1 is the sectional view under the user mode of the utility model;
Fig. 2 is the sectional view under the unused state of the utility model.
Embodiment
Below in conjunction with accompanying drawing and embodiment, the embodiment of the utility model is described in further detail.Following examples are used to explain the utility model, but are not used for limiting the scope of the utility model.
As depicted in figs. 1 and 2, the novel pump of the utility model comprises cylindrical shell 1 and holding rod 2; The below of holding rod 2 is provided with piston rod 12, and the set inside of cylindrical shell 1 has piston 3, and the below of piston rod 12 is passed cylindrical shell 1 and is connected with cylindrical shell 1 interior piston 3; Cylindrical shell 1 wall is provided with air outlet hole 4, and in cylindrical shell 1 outer installment the connecting tube 5 that communicates with air outlet hole 4 is arranged, and the end of connecting tube 5 is provided with fixing head; Also be provided with the fixedly plug 6 and backflush device 7 that have pore in the cylindrical shell 1; Cylindrical shell 1 top is provided with inlet hole 8, and fixing plug 6 is between piston 3 and air outlet hole 4, and fixing plug 6 is fixed in the cylindrical shell 1; Backflush device 7 is positioned at the pore of fixing plug 6, and backflush device 7 links together with cylindrical shell 1 inwall through first spring 9; Like this, in use, depress holding rod drive piston and move downward; At this moment, through air-flow backflush device is extruded in the pore of fixing plug, air flows to the air outlet hole place in the pore of fixing plug; After mentioning holding rod, because the effect of first spring, backflush device is back in the pore of fixing plug again; Block pore, thereby prevented counter the inputing in the cylindrical shell of air in the tire, easy-to-operat also increases working efficiency.
The novel pump of the utility model; Also be provided with seal ring 10 between piston 3 and the fixing plug 6, when depressing holding rod 2, holding rod 2 drives piston 3; The bottom of piston 3 is passed seal ring 10 and is driven seal ring 10; Like this, can prevent that air-flow from flowing out from inlet hole when depressing holding rod, better guarantee working efficiency.
The novel pump of the utility model also is provided with second spring 11 between piston 3 and the fixing plug 6.
The novel pump of the utility model, inlet hole 8 is 4.
The above only is the preferred implementation of the utility model; Should be understood that; For those skilled in the art; Under the prerequisite that does not break away from the utility model know-why, can also make some improvement and modification, these improvement and modification also should be regarded as the protection domain of the utility model.
