Abstract
The utility model provides a unidirectional air needle, consisting of a needle head and a needle holder arranged at the end of the needle head. The utility model is characterized in that the needle holder is arranged with a check valve comprising an ektexine, an inner hole, and a spring and a choke plug arranged inside the inner hole. Because a check valve is arranged on the needle holder of the air needle, air can only flow in a unidirectional way, thereby efficiently preventing air from flowing back. Besides, the lower port of the needle holder is designed with a plane port, thereby solving the problem that the air needle is prone to air leakage when being charged. The utility model is simple in structure, easy to operate and convenient to carry, which is really a next-generation ideal and applied unidirectional air needle.
Description
Technical field
The utility model relates to a kind of air tube, especially a kind of air tube of giving sport ball class aeratings such as basketball, vollyball, football.
Background technique
Air tube is that various physical culture are ball as indispensable inflation pins such as basketball, vollyball, footballs with inflation, can keep the gas of these balls abundant by it.But present air tube exists unreasonable structure, always Lou Qi problem.Trace it to its cause, mainly contain 3 points.The one, the needle holder upper end-hole of air tube is excessive, can not combination mutually be arranged with the filling gas mouth of inflator, causes gas leakage herein easily; The 2nd, the needle holder lower end surface of air tube all is an arc surface, makes the clip of inflator slide to a side easily, thereby causes gas leakage; The 3rd, do not prevent the device of gas backstreaming, when taking off the clip of inflator, gas flows out from the upper end-hole of air tube at once, causes under-inflation.Therefore, be necessary existing air tube is improved.
Summary of the invention
The purpose of this utility model is to overcome the deficiency of prior art, provides a kind of and does not reflux, Single-way inflating needle air tight and simple in structure.
The utility model is realized by following technical proposal: it comprises syringe needle and be located at the needle holder that syringe needle is not held, and it is characterized in that needle holder is provided with by outer wall, endoporus and is located at spring in the endoporus and safety check that plug constitutes.
The endoporus of described safety check is communicated with the syringe needle endoporus of bottom and the inlet end on top respectively, so that gas enters in the ball through this endoporus and syringe needle endoporus.
Spring in the described safety check endoporus is positioned at the below, and plug is positioned at the spring top and places on the gas channel mouth, so that gas can only unidirectionally be flowed into.
Described plug is spheroid or hemisphere or cone or other shape.
The lower end mouth of described air tube needle holder is a plane port, and needle holder does not slide when preventing to inflate.
The utility model compared with prior art has following advantage and effect: owing to be provided with safety check on the needle holder of air tube, gas can only unidirectionally be flowed into, thereby effectively prevented the backflow of gas, the lower end mouth of needle holder is made as the plane port in addition, therefore, has solved the problem that air tube leaks gas easily when inflation, the utility model also has simple in structure in addition, easy to operate, characteristics such as be easy to carry, real be comparatively ideal, practical Single-way inflating needle of a new generation.
Embodiment
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the sectional arrangement drawing of Fig. 1.
Below in conjunction with accompanying drawing the utility model is described further.
Among the figure, 1 is syringe needle, being provided with through hole 2,3 in it is needle holder, is made of subiculum 4 and pop-up 5, the top of pop-up 5 is inlet end 8, the bottom of subiculum 4 is outlet side 12, and this port is a planar ends, and the middle part is an endoporus 11, this endoporus is communicated with inlet end and outlet side respectively, spring 6 is equipped with in the bottom of endoporus 11, and spheroid plug 7 is equipped with on top, when the inlet end 8 of superheated steam from top enters, promoting spring 6 drive plugs 7 moves down, promptly open passage and make gas enter endoporus 11, enter in the ball through syringe needle endoporus 2 again, when stopping air feed, plug 7 moves under spring 6 effect and blocks passage 9, prevents gas backstreaming by sealing gasket 10.
Claims (5)
1, a kind of Single-way inflating needle, it comprises syringe needle and be located at the needle holder that syringe needle is not held, and it is characterized in that needle holder is provided with by outer wall, endoporus and is located at spring in the endoporus and safety check that plug constitutes.
2, air tube according to claim 1 is characterized in that the endoporus of described safety check is communicated with the syringe needle endoporus of bottom and the inlet end on top respectively.
