Description

Pump and its holder

The present invention relates to an inflator and its fixing bracket. The inflator can be firmly coupled to a bicycle through the fixing bracket.

It is known that a portable pump can be fixed on a bicycle frame through a fixed frame so that it can be carried around while riding. However, traditional fixing brackets fix the cylinder of the pump. When riding a bicycle, the parts of the pump that reciprocate relative to the cylinder, such as the grip or the valve head, are not limited in position, causing the parts of the pump to move. As the bicycle moves forward, it makes uncontrolled reciprocating motion relative to the cylinder, causing components to hit the cylinder and produce sound. Not only is the pump easily damaged, but it is also easy to fall off from the fixed frame.

This new invention provides an inflator and its fixing bracket. The inflator can be firmly coupled to the bicycle through the fixing bracket and limited in position, thereby preventing the inflator from making uncontrolled reciprocating motion as the bicycle moves forward.

The embodiment of the present invention provides an inflator and its fixing bracket, which includes an inflator and a fixing bracket. The pump has a fixed end and a reciprocating end that can reciprocate relative to the fixed end, and a first limiting portion is provided on the outer edge of the pump. The fixed frame has a fixing part suitable for being fixed on the bicycle, a clamping part detachably clamping the pump, and a second limiting part detachably engaged with the first limiting part.

In one embodiment of the present invention, the first limiting part is provided on the outer edge of the fixed end, and the clamping part detachably clamps the reciprocating end.

In one embodiment of the present invention, the first limiting part is in the shape of a slot, and the second limiting part is in the shape of a bump and is detachably engaged with the first limiting part.

In one embodiment of the present invention, the fixing bracket extends outward from the clamping part to form an extension part, and the second limiting part is formed at the end of the extension part.

In one embodiment of the present invention, the fixing frame is provided with a strap on one side of the clamping part, and a hook is provided on the other side of the clamping part. The strap is detachably hooked on the hook to fix the tying machine. The reciprocating end of the air cylinder.

In one embodiment of the present invention, the pump includes a cylinder group. The cylinder group includes an inner cylinder, an outer cylinder that is reciprocally movably sleeved on the inner cylinder, and a head base fixed to one end of the inner cylinder. The fixed end and the first limiting part are arranged on the head base, and the reciprocating end is arranged on the outer cylinder.

In one embodiment of the present invention, the air pump further includes an inflation group, and the inflation group includes a sliding seat, an air tube and a pivot joint. The sliding seat is arranged in the inner cylinder and is provided with an air outlet communicating with the inner cylinder. One end of the trachea is connected to the pivot joint. The pivot joint is provided with a communication hole that communicates with the air pipe and selectively communicates with the air outlet. The pivot joint is pivotally connected to the sliding seat and can pivot between the axial position and the radial position relative to the sliding seat. When the pivot joint is in the axial position, the sliding seat can move between the retracted position and the extended position relative to the inner cylinder. When the slide is in the retracted position, the slide is adjacent to the reciprocating end and maintains the pivot joint in the axial position. When the sliding seat is in the extended position, the sliding seat is adjacent to the fixed end, and when the pivot joint is in the radial position, the sliding seat remains in the extended position and the communication hole is connected to the air outlet.

In one embodiment of the present invention, an opening communicating with the first limiting portion is provided at an end of the headstock opposite to the inner cylinder. When the sliding seat is in the extended position and the pivot joint is in the axial position, the air pipe extends out of the headstock through the opening. When the pivot joint is in the radial position, the air pipe extends out of the head base from the first limiting part. When the sliding seat is in the retracted position, the trachea does not extend out of the opening.

In an embodiment of the present invention, the cylinder group further includes a cover, which is detachably connected to the opening and capable of closing the opening. The cover is provided with an anti-lost part. The anti-lost part is flexible and can be deformed, and the anti-lost part is always connected to the head base.

In one embodiment of the present invention, the sliding seat is provided with an air-tight component in the air outlet hole, and the pivot joint is constantly in contact with the air-tight component when pivoting between the axial position and the radial position, and when the pivot joint is in the axial position, The connecting hole is not connected to the air outlet.

Based on the above, in the inflator and its holder provided by the embodiment of the present invention, the inflator can be firmly combined through the limiting relationship between the clamping part of the holder and the first and second limiting parts. to the bicycle and be restrained to prevent the pump from making uncontrolled reciprocating motion as the bicycle moves forward.
