Description
Technical field
The utility model belongs to the attached apparatus technical field of ball sporting appliance, is specifically related to a kind of novel bidirectional ball pin.
Background technology
At present, utilizing ball to carry out inflating for ball sporting appliances such as basketball, vollyball, footballs is conventional method.Traditional inflatable ball pin is mostly unidirectional, comprises an air inlet pipe, and one end of air inlet pipe is provided with intake interface, and the other end of air inlet pipe is provided with air inlet needle tubing.During inflation, be stuck on intake interface with the pump adaptor of inflator, air inlet needle tubing inserted the inflation inlet of spheroid, utilize air inlet pipe to inflate toward inflation inlet.But in most cases, people grasp aeration quantity and with great difficulty do not cause aeration quantity in ball excessive, if when spheroid internal gas pressure is higher, traditional one-way ball needle is utilized not easily to release unnecessary gas, and the very difficult control of discharge quantity, cause gas in ball cannot reach desired level all the time, extremely inconvenient when reality uses.In addition, when traditional one-way ball needle pulls away the inflation inlet of spheroid, always there will be back flow of gas phenomenon in various degree, affect ball internal gas pressure size and change.
In view of above-mentioned prior art, be necessary to be improved the structure of existing ball pin, for this reason, the applicant has done useful design, and technical scheme described below produces under this background.
Summary of the invention
The purpose of this utility model is to provide a kind of novel bidirectional ball pin, and its structure is simple, conveniently exits in right amount, and can prevent back flow of gas, be conducive to the conservative control of aeration quantity in spheroid.
The purpose of this utility model reaches like this, a kind of novel bidirectional ball pin, it is characterized in that: comprise the shell with shell chamber, described shell is provided with air inlet pipe in the upper end of short transverse, described air inlet pipe is configured with intake interface in upper port, intake interface is communicated with shell chamber via air inlet pipe, shell is provided with air inlet needle tubing in the lower end of short transverse, the upper port of described air inlet needle tubing probes into in shell chamber, air inlet needle tubing is a sheathed back-moving spring at upper port place, one end of described back-moving spring is supported on the diapire in shell chamber, the other end of back-moving spring is connected with the stopper for closed air inlet pipe lower port, air inlet needle tubing is leaning out shell chamber and offering exhaust outlet on the tube wall at lower port place.
In a specific embodiment of the present utility model, the shape of described stopper is lower end towards the circular cone stage body of upper extreme direction narrow contracting gradually, stopper is in lower end and along the circumferential direction form seal boss, when stopper is from back-moving spring is stressed and when being pushed in air inlet pipe, the roof in described seal boss and shell chamber is tightly connected.
In another specific embodiment of the present utility model, described stopper is rubber parts.
In another specific embodiment of the present utility model, the shape of described exhaust outlet is circular port or rectangular opening or irregularly-shaped hole.
The utility model is owing to have employed said structure, compared with prior art, the beneficial effect had is: when inflating spheroid, when outside part is extracted air inlet needle tubing and makes exhaust outlet be exposed to spherome surface, the gas be filled with in ball discharges by exhaust outlet, thus can the size of conservative control ball internal gas pressure; The cooperation of back-moving spring and stopper, can prevent back flow of gas, effectively avoids gas in ball to leap up out when extracting air inlet needle tubing completely, thus impact inflation effect.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1. shell, 11. shell chambeies; 2. air inlet pipe, 21. intake interfaces; 3. air inlet needle tubing, 31. exhaust outlets; 4. back-moving spring; 5. stopper, 51. seal bosses.
Detailed description of the invention
Applicant will describe in detail detailed description of the invention of the present utility model below by reference to the accompanying drawings; but applicant is not the restriction to technical scheme to the description of embodiment, any changing in the form rather than substance according to the utility model design all should be considered as protection domain of the present utility model.
Refer to Fig. 1, the utility model relates to a kind of novel bidirectional ball pin, comprise the shell 1 with shell chamber 11, described shell 1 is provided with air inlet pipe 2 in the upper end of short transverse, described air inlet pipe 2 is configured with the intake interface 21 for connecting inflator in upper port, and intake interface 21 is communicated with shell chamber 11 via air inlet pipe 2.Shell 1 is provided with the air inlet needle tubing 3 for inserting spheroid inflation inlet in the lower end of short transverse, the upper port of described air inlet needle tubing 3 probes into in shell chamber 11, is communicated with shell chamber 11.Air inlet needle tubing 3 is a sheathed back-moving spring 4 at upper port place, and one end of described back-moving spring 4 is supported on the diapire in shell chamber 11, and the other end of back-moving spring 4 is connected with the stopper 5 for closed air inlet pipe 2 lower port.The shape of described stopper 5 is lower end towards the circular cone stage body of upper extreme direction narrow contracting gradually, stopper 5 in lower end and along the circumferential direction forms seal boss 51, when stopper 5 from back-moving spring 4 stressed and push in air inlet pipe 2 time, described seal boss 51 is tightly connected with the roof in shell chamber 11.In the present embodiment, described stopper 5 is rubber parts.Air inlet needle tubing 3 is leaning out shell chamber 11 and offering exhaust outlet 31 on the tube wall at lower port place, and the shape of described exhaust outlet 31 can be circular port or rectangular opening or irregularly-shaped hole, in the present embodiment preferably circular port.
Please continue to refer to Fig. 1, operation principle of the present utility model is described further.When adopting this ball to inflate for spheroid, the lower port of air inlet needle tubing 3 is inserted spheroid inflation inlet, and the exhaust outlet 31 on air inlet needle tubing 3 is also submerged in spheroid, air inlet pipe 2 is connected with inflator by intake interface 21.When inflating, stopper 5 backs down by gas, and extraneous gas enters in spheroid via shell chamber 11 and air inlet needle tubing 3.When aeration quantity in ball is excessive, needs are suitable when deflated, only partly need extract air inlet needle tubing 3, make exhaust outlet 31 be exposed to spherome surface, now in ball, gas is discharged via exhaust outlet 31, when aeration quantity reaches desired level in ball, extract air inlet needle tubing 3 completely, terminate inflation.In addition, when stopping inflating, stopper 5 can under the screen resilience effect of back-moving spring 4, move upward and push in air inlet pipe 2, and seal boss 51 and shell chamber 11 roof of stopper 5 are tightly connected, prevent back flow of gas, effectively avoid gas in ball to leap up out when extracting air inlet needle tubing 3 completely, thus affect ball internal gas pressure size.
