Abstract
The utility model relates to a tyre inflating grip holder, which belongs to the technical field of tyre inflation interface. At present, an iron clamping type inflation interface which is commonly used for an inflating pump adopts an end face seal and clamping mode, which easily results in gas leakage caused by loose end face contact. Aiming at the problems, the utility model adopts a method of column surface axial sealing and clamping and a light tyre inflating grip holder is designed. The utility model is composed of a grip holder outer sleeve 1, a rubber sealing sleeve 2, an inflating joint body 3 and a cam handle. When the utility model is used, step-shaped through holes of the grip holder outer sleeve are positioned on an air door cap of an air valve, and the cam handle is rotated to extrude the rubber sealing sleeve to be deformed to realize sealing and clamping tightly the air valve of the tyre.
Description
The utility model relates to a kind of enclosed type inflation of tire chuck, and it belongs to inflation of tire interfacing field.
At present, the air valve on the vehicle tyre mainly is divided into two kinds of air tube spring loaded and valve inside formulas, inflates interface accordingly and is divided into thimble-type and iron clamp formula.Because what be used for that iron clamp formula inflation interface on the light tyres such as bicycle, rickshaw adopts is side seal, clamps form, cause the end face contact unreal and leak gas during use easily.
The purpose of this utility model is at the problems referred to above, adopts the method for face of cylinder side seal and clamping, designs a kind of inflation of tire chuck that is applicable to valve inside formula air valve.Four kinds of parts are made with plastics and elastomeric material respectively in this product.Iron clamp formula inflation interface on this product and the Floor Pump is compared, and has easy and simple to handle, good sealing effect, low cost and other advantages.
Accompanying drawing and this accompanying drawing of label declaration are inflation of tire chuck generalized section.Label: 1-chuck overcoat; The 2-rubber sealing boot; 3-gas-charging connection body
The 4-cam handle; The 5-bearing pin
The utility model is to realize like this (referring to accompanying drawing):
The inflation of tire chuck, its technical essential is: interface is by chuck overcoat 1, rubber sealing boot 2, gas-charging connection body 3, cam handle 4 constitutes.The chuck overcoat is a hollow structure, its bottom is provided with the stepped appearance open-work that connects Tyre air valve, one side of chuck overcoat has chute, rubber seal is sleeved on the bottom of chuck overcoat, the gas-charging connection body is housed on it, cam handle is connected the top of chuck overcoat through bearing pin 5, and cam handle contacts with the last plane of gas-charging connection.
Below, the other technologies feature is launched explanation:
Rubber sealing boot 2 is a circular configuration, the high 4～6mm of rubber coating, and wall thickness 2.5～3mm, inside face are provided with the twice annular boss, and its internal diameter is identical with the open-work of chuck overcoat 1 bottom.
Gas-charging connection body 3 is a circular configuration, and the air extractor vent on its sidewall connects gas piping, and is provided with the screw thread that is connected with the gas piping of common Floor Pump.
The cam of cam handle 4 has two plane of orientations, and angle is 110～125 °.
Principle of work of the present utility model is:
1, when inflation is sleeved on this tire Inflation clamping head on the air valve of valve inside formula, and the end outside face of the stepped appearance open-work of chuck overcoat is positioned on the valve cap on the plane.
2, by the effect of cam handle 4, the gas-charging connection body is exercised rubber sealing boot 2 for 3 times and is produced deformation, finishes the sealing location and clamps Tyre air valve, and enter the inflation of tire state.
3, when air pressure meets the requirements of numerical value,, remove inflated condition rapidly by the effect of cam handle.
The utility model embodiment sees accompanying drawing, and the chuck overcoat is φ 15 * 34.5mm, and the bottom is the stepped appearance open-work, is respectively φ 10 * 8, and φ 5.The gas piping front end of gas-charging connection body is provided with Floor Pump matches and connects screw thread.
