Problems solved by technology

[0003] (1) When the key is put into the keychain, the end part of the keychain needs to be broken by hand to provide the key entrance for the key, and the key entrance needs to be kept open until the hanging hole of the key is covered at the broken end Part of the periphery, in this way, not only laborious, but also inconvenient to insert the key
[0004] (2) When the key is just set on the end of the end part, after loosening the broken end part, the key is easily ejected from the keychain due to the clamping force between the two end parts. At this time, repeat the above The operation of putting the key into the key fob further increases the difficulty of putting the key in

Embodiment Construction

[0026] In order to solve the problem that it is laborious and difficult to put the key into the keychain in the prior art, the present invention provides a keychain that is convenient for the key to be put in, which includes an iron core with tension so that its two ends The upper and lower parts are arranged to form a ring structure and at least one top-opening part.

[0027] Please also see figure 2 and image 3 , the annular structure includes a first end portion 1 and a second end portion 2 that can be expanded, and a ring body 3 sandwiched by the first end portion 1 and the second end portion 2 . The first end portion 1 defines a first through hole 11 whose axis is perpendicular to the ring body 3 .

[0028] The top-opening member 4 is arranged in the first through hole 11 and can move along the axial direction of the first through hole 11 , and an outer diameter larger than that of the first through hole 11 is sheathed on the periphery of one end thereof. The limitin...

Abstract

The invention relates to a key ring allowing keys to be placed therein conveniently. The key ring comprises an annular structure and at least one ejector part, wherein the annular structure is formed in the mode that an iron core with tension is wound and two ends of the iron core are arranged vertically. The ann ular structure comprises the first end and the second end which can be open, and a ring body clamped by the first end and the second end. The first end is provided with a first through hole with the axis perpendicular to the ring body. The ejector part is arranged in the first through hole and can move in the axial direction of the first through hole, one end of the ejector part is sleeved with a limiting part, the outer diameter of the limiting part is larger than the hole diameter of the first through hole, the limiting part is clamped between the outer end of one hole opening of the first through hole and the ring body, and the other end of the ejector part extends out of the other hole opening of the first through hole. According to the key ring, the keys can be placed in the key ring conveniently, the difficulty caused when the keys are placed in is lowered, and labor is saved.

Description

technical field [0001] The invention relates to the field of daily necessities for carrying keys, in particular to a key chain which is convenient for key insertion. Background technique [0002] Key chains are generally used to hang multiple keys together for easy carrying and storage. see figure 1 , the existing conventional key chain is generally wound with a certain size through a circular iron core with tension, so that its two end parts (the first end part a1 and the second end part a2) overlap to form a circular shape keychain. When the key is to be put into the key chain, one of the end parts of the key chain needs to be broken apart by hand, for example, the first end part a1 is broken apart, so that the first end part a1 and the ring body a3 separates, thereby forming a key entry. Subsequently, after the first end portion a1 is inserted into the hanging hole of the key, the first end portion a1 is released, and the top end portion of the key is sandwiched betwe...
