Description

The invention relates to a rotatably operated pump head for an English valve.

The bicycle tire usually has an American, French or English valve. These valves have their own advantages and disadvantages.

When pumping through an English valve, a corresponding pump head is required. The conventional pumphead for an English valve has a complicated structure, higher cost, and not easy handling.

From the DE 200 00 597 U1 An air hose assembly for a portable tire pump is known, comprising an air nozzle threaded sleeve and an air hose assembly, wherein the air nozzle threaded sleeve is provided with a lay-on rubber ring, a hollow core, an air nozzle threaded sleeve, a connecting screw, a washer, a tension spring, an insert threaded tube, a valve tube rubber ring, a rear threaded sleeve , a fastening ring and an air hose.

The DE 815 751 B discloses a tubeless air pump with nipple and tensioning device, wherein by the movement of the tensioning device in the clamping position of a compressed by a movable part of the nipple rubber ring is compressed, so that its passage opening is reduced.

From the US 2010/0054962 A1 is a mini-pump with a head, a cylinder and a pipe known.

From the US 6382268 B1 For example, an inflator having a first portion and a second portion is known wherein the first portion has a threaded recess and the second portion has an insert.

From the US 2004/0055641 A1 For example, there is known a universal air valve connecting device comprising an outer cylindrical connecting part, an inner cylindrical connecting part, anti-rotation means, locking means, means for connecting an air hose to said connecting parts, and activating means.

The invention has the object to provide a rotatably operated pump head for an English valve, which has a simple structure, low production costs and easy handling.

This object is achieved by the inventive rotary actuated pump head for English valve, comprising: a main body having a receiving recess and a valve opening which is connected to the receiving recess, wherein the main body at the other end has an insertion opening with the receiving recess is connected, wherein the receiving recess has two opposite axial Gleitnuten; an insert having a base body and an axial pump hole passing through the base body, the base body having an external thread and two opposing slides, the slides being able to slide back and forth along the sliding grooves of the main body; a knob having a base body and an internal thread in the base body, wherein the base body is rotatable with the main body, wherein the internal thread of the rotary knob is screwed onto the external thread of the insert; and a hose connected to the insert.

In the following the invention with reference to embodiments with reference to the drawings will be described in detail. In the drawing shows

1 an exploded view of a preferred embodiment of the invention,

2 a perspective view according to 1 .

3 a sectional view according to 1 .

4 to 7 Representations of the movement according to 1 and

8th a perspective view of another embodiment of the invention.

The 1 to 7 show a preferred embodiment of the rotary actuated pump head according to the invention for an English valve 100 who has a main body 10 , an insert 20 , a knob 30 , a hose 40 , a sleeve 50 and a soft ring 60 includes.

Like from the 1 to 3 it can be seen, the main body 10 a receiving recess 11 and a valve opening 12 on, with the receiving recess 11 connected is. The main body 10 has an insert opening at the other end 13 on, with the receiving recess 11 connected is. The receiving recess 11 has two opposite axial sliding grooves 14 ,

Like from the 1 to 3 can be seen, indicates the use 20 a basic body 21 and an axial pump hole 22 on, that through the main body 21 passes. The main body 21 has a hose connection part 211 , a valve connecting part 212 and an external thread 213 between the hose connection part 211 and the valve connecting part 212 , The valve connection part 212 forms on the outside two opposite slides 214 , The sliders 214 can along the slide grooves 14 of the main body 10 glide back and forth.

Like from the 1 to 3 can be seen, the knob points 30 a basic body 31 and an internal thread 32 in the main body 31 on. The knob 30 forms several hooks at one end 311 in the knob opening 13 of the main body 10 be plugged, causing the main body 10 is rotatably connected. The internal thread 32 the knob 30 is on the external thread 213 of the insert 20 screwed.

Like from the 1 to 3 it can be seen, one end of the hose 40 through the internal thread 32 the knob 30 passed and over the hose connection part 211 of the insert 20 plugged. The other end of the hose 40 is connected to an air pump or an air tank (not shown).

Like from the 1 to 3 it can be seen, the sleeve is used 50 for clamping the hose 40 at the hose connection part 211 of the insert 20 to loosen the hose 40 from the insert 20 to avoid.

Like from the 1 to 3 It can be seen, the soft ring 60 be deformed by an external force and is in the valve connection part 212 of the insert 20 arranged.

The operation of the rotary actuated pump head according to the invention for English valve 100 described.

When inflating through an English valve 91 ( 3 ) will first turn the knob 30 turned. Through the internal thread 32 and the external thread 213 will be the use 20 along the slide grooves 14 towards the insert opening 13 emotional ( 4 ). Subsequently, the English valve 91 in the receiving recess 11 of the main body 10 be plugged, thereby ending 912 of the English valve 91 the use 20 is facing ( 5 and 6 ). After that, the knob will turn 30 turned in the other direction, causing the use 20 in the direction of the valve opening 12 is moved so that the soft ring 60 in the valve connection part 212 of the insert 20 over the end 912 of the English valve 91 is plugged ( 7 ). Therefore, the air from the air pump or the air tank into the English valve 91 be filled.

The invention has a simple structure, whereby the costs are significantly reduced. By turning the knob, the invention can be easily connected to the English valve, so that the handling is easy.

How out 8th It can be seen, in addition to the English valve, an adapter for American and French valve 92 in the receiving recess 11 be plugged. Thereby, the pump head according to the invention can be connected not only with an English valve but also with an American or French valve, so that the scope of the invention is great.

The foregoing description represents only the preferred embodiments of the invention and is not intended to serve as a definition of the limits and scope of the invention. All equivalent changes and modifications are within the scope of this invention.
