Background technology
The tire of bicycle generally need dock the valve and the tire tube valve on the tire of Floor Pump, thereby air is poured in the tire when inflating.But, take turns the less bicycle in footpath for some, the bicycle of children's ride-on for example is because the wheel of its wheel footpath is little; And support frame is thicker, and tire tube valve also has certain altitude, therefore causes the space between tire tube valve and the support frame narrow and small; Be difficult for the clip of Floor Pump is clamped on the tire tube valve, thereby cause the valve of Floor Pump to be difficult for accurately docking, cause in the process of inflating with the tire tube valve of tire; Clip comes off easily, needs the user again clip to be buckled, and is therefore very inconvenient.
The utility model content
In view of this, be necessary to provide a kind of valve of Floor Pump and easy adapter substitute that is communicated with of tire tube valve of bike tyre of making.
The utility model is achieved in that a kind of adapter substitute; Be used to connect the valve of Floor Pump and the tire tube valve of bike tyre, said adapter substitute comprises the intermediate pipe of joint, air inlet pipe and jointing and air inlet pipe, and said intermediate pipe has the switching air flue; Said joint is connected in the bottom of said intermediate pipe; Offer screw in the said joint, said screw is communicated with said switching air flue, and said air inlet pipe is connected in the sidewall of said intermediate pipe; Offer induction opening in the said air inlet pipe, said induction opening is communicated with said switching air flue.
Preferably, said intermediate pipe bottom offers the seal groove that is communicated with said switching air flue, and said adapter substitute also comprises seal ring, and said seal ring is contained in the said seal groove.
Preferably, said joint and intermediate pipe bonded assembly end also convex with steady ring, and the bottom of said intermediate pipe is inserted in the said steady ring.
Preferably, offer the accepting groove that is communicated with said switching air flue on the sidewall of said intermediate pipe, an end of said air inlet pipe offers screw thread, forms coupling end, and said coupling end inserts in the accepting groove, and screws togather with the inwall of accepting groove.
Preferably, convex with the location division on the outer wall of said air inlet pipe.
With respect to prior art, the adapter substitute that the utility model provides can make the valve of Floor Pump be communicated with at an easy rate with the tire tube valve of tire, and can not receive the obstruction of the skeleton of wheel, is convenient to tire is inflated.
Above-mentioned explanation only is the general introduction of the utility model technical scheme; In order more to know the technological means of understanding the utility model; And can implement according to the content of specification sheets, and for let the above-mentioned of the utility model with other purpose, feature and advantage can be more obviously understandable, below special act embodiment; And conjunction with figs., specify as follows.
Description of drawings
Below in conjunction with accompanying drawing the embodiment of the utility model is described, wherein:
Fig. 1 is the block diagram of the adapter substitute of the utility model embodiment.
Fig. 2 is the cutaway view of the adapter substitute of Fig. 1.
Fig. 3 is the running condition scheme drawing of the adapter substitute of Fig. 1.
The specific embodiment
Below be further elaborated based on the specific embodiment of accompanying drawing to the utility model.Should be appreciated that specific embodiment described herein as just embodiment, and be not used in the protection domain that limits the utility model.
Please refer to Fig. 1 to Fig. 2, the adapter substitute 1 that the utility model embodiment is provided is used to be installed in the tire tube valve 21 of cycle wheel 2.This adapter substitute 1 comprises the intermediate pipe 12 of joint 11, air inlet pipe 14 and jointing 11 and air inlet pipe 14.
Joint 11 is for offering the screwed pipe of screw.Intermediate pipe 12 has L-shaped switching air flue 121, seal groove 122 and accepting groove 123.Seal groove 122 is positioned at the bottom of intermediate pipe 12, and is communicated with joint 11 in-to-in screws.Accepting groove 123 is positioned on the sidewall of intermediate pipe 12, is used to connect air inlet pipe 14.An opening of switching air flue 121 is positioned on the sidewall of intermediate pipe 12, is communicated with accepting groove 123, and another opening is positioned at the bottom of intermediate pipe 12, and is communicated with seal groove 122.Joint 11 also convexes with steady ring 111 with intermediate pipe 12 bonded assembly ends, and the bottom of intermediate pipe 111 is positioned on the joint 11.This adapter substitute 1 also comprises seal ring 13, and seal ring 13 is contained in the seal groove 122.Offer induction opening 141 in the air inlet pipe 14.Convex with location division 142 on the outer wall of air inlet pipe 14, wherein an end then offers screw thread, forms coupling end 143.Coupling end 143 inserts in the accepting groove 123 of intermediate pipes 12, and screws togather with the inwall of accepting groove 123, thereby air inlet pipe 14 is connected with intermediate pipe 12.
Please refer to Fig. 3, the adapter substitute 1 that the utility model provides in use, joint 11 is set in interior mouth 211 outsides of tire tube valve 21, thus the air flues 214 in the mouth 211 are communicated with the air flue 121 of transferring in making.Also be arranged with air cushion 215 outside the end of the interior mouth 211 of tire tube valve 21 with tire 22 internal communication; The position of air cushion 215 is corresponding with the opening part of air flue 214; Be used for the opening of closed airway 214 under normal conditions, when inflating state, be communicated with air flue 214 and tire 22 inside.Tire tube valve 21 is connected with the valve 31 of Floor Pump through this adapter substitute 1.Valve 31 is communicated with air inlet pipe 14 interior induction openings 141, and the clip 32 on the valve 31 is clamped on the air inlet pipe 14, and is positioned at the side of location division 142 near coupling end 143.Clip 32 receives stopping of location division 142, thereby makes valve 31 keep being connected with air inlet pipe 14.Then, inflated by Floor Pump, air gets into the inside of tire 22 at last successively through valve 31, induction opening 141, switching air flue 121, air flue 214, air cushion 215.
The adapter substitute that the utility model provides can make the valve of Floor Pump be communicated with at an easy rate with the tire tube valve of tire, and can not receive the obstruction of the skeleton of wheel, is convenient to tire is inflated.
The above is merely the preferred embodiment of the utility model, not in order to restriction the utility model, interior any modification of doing of all spirit at the utility model and principle, is equal to and replaces and improvement etc., all should be included in the protection domain of the utility model.
