Description

TECHNICAL FIELD

[0001] The utility model relates to a valve core, concretely relates to a quick deflation valve core convenient to install. BACKGROUND

[0002] The valve core is a valve body structure for realizing inflation and deflation. It is usually arranged on the valve seat of a hub and used for the inflation and deflation of a tire. The conventional valve core needs to manually screw out the valve core from the valve core for deflation, which is troublesome and slow in deflation efficiency due to the small air hole. The Chinese patent document (publication number: CN221463018U; publication date: August 2, 2024) discloses a quick deflation valve core, which comprises a gas valve body, the gas valve body is provided with a gas passage formed by the communication of the holes at both ends, the gas valve body is provided with a valve core cover at the upper end and is fixedly connected with a tire cavity at the lower end, the gas passage is communicated with the tire cavity, the upper end of the gas passage is provided with a valve core, characterized in that a sliding seat is sleeved on the gas valve body, the sliding seat can slide axially along the gas valve body, the gas valve body is provided with an exhaust hole communicated with the gas passage, the sliding seat can slide to close the exhaust hole or make the exhaust hole communicated with the outside, and the gas valve body is further provided with a limiting structure limiting the sliding range of the sliding seat.

[0003] The defect of the above technical solution is that one end of the entire gas valve body needs to be fixedly installed on the hub. When the hub using the conventional valve core is replaced with the above valve core, the entire original valve core body on the hub needs to be removed, and then the gas valve body is fixed on the hub, which makes the installation and replacement operation very troublesome. In order to be able to be installed and connected, the length of the entire gas valve body needs to be set very long, which leads to a large size and high production cost, and the assembly is also troublesome. UTILITY MODEL CONTENTS

[0004] In view of the deficiencies in the background art, the technical problem to be solved by the utility model is to provide a quick deflation valve core convenient to install for solving the above problems.

[0005] To this end, the utility model is implemented by the following scheme:

[0006] A quick deflation valve core of convenient installation, comprising a valve body, a gas passage is formed in the middle of the valve body, a detachable valve core cover is arranged on the top of the valve body, a valve core is arranged at one end of the gas passage, a sliding cover is arranged outside the valve body, an exhaust hole is formed in the side wall of the valve body and communicated with the gas passage, and the sliding cover can block one end of the exhaust hole, characterized in that: an inner thread is arranged on the inner hole wall of the other end of the gas passage, and the inner thread can be screwed with the outer thread of the valve core body on the hub, so that the gas passage is communicated with the inner cavity of the tire through the inner hole of the valve core body.

[0007] A limiting arm is arranged on the bottom of the sliding cover, a hook claw part is arranged at the end of the limiting arm, the hook claw part can abut against the limiting step on the valve body, and at this time, the exhaust hole is communicated with the outside.

[0008] The top of the sliding cover can abut against the valve core cover installed on the valve body, and the sliding of the sliding cover is limited.

[0009] Sealing rings are arranged on the upper and lower sides of the exhaust hole of the valve body, and the sealing rings can cooperate with the sliding cover to close one side of the exhaust hole.

[0010] A sealing gasket is arranged in the valve body, and the sealing gasket can abut against the top of the valve core body.

[0011] The quick deflation valve core of convenient installation can realize inflation and quick deflation operation, and can be screwed with the valve core body originally installed on the hub, so that the valve core can be installed only by disassembling the valve core in the original valve core body, without disassembling the original valve core body on the hub, and the operation is simpler and more universal.
