Technical Field

The invention relates to daily necessities, in particular to a multipurpose key ring.

Background

The key is the most commonly used unlocking tool in people's life, in order to conveniently carry and prevent losing, usually a plurality of keys are strung together with the key ring by using the key ring, for example, a hook type key ring comprises a hook and a key ring connected with the hook, when people pack the key into the key ring, the opening of the key ring needs to be knocked open by fingers to put the key in, the mounting method is labor-consuming, if the nail is short, the key ring is difficult to knock open, and the nail is easy to be injured, technical personnel in the field hope that a multifunctional key ring can be provided, so that the problem that the key is difficult to pack into the key ring is solved.

Disclosure of Invention

The invention aims to overcome the defects in the prior art and provide a multipurpose key ring.

In order to achieve the purpose, the technical scheme adopted by the invention is as follows: a multipurpose key ring comprises a hook, a slide bar, a slide ring and a key ring; one end of the sliding rod is connected with the hook, the sliding rod body is sleeved in the sliding ring, the other end of the sliding rod body is provided with a ring opening head, and the ring opening head is used for propping against a gap between two rings of the key ring to open the rings; the sliding ring comprises a sliding sleeve and a ring connected with the sliding sleeve, the ring is mutually connected with the key ring in an encircling way, and the open ring head of the sliding rod is positioned in the ring.

Furthermore, a limiting structure is further arranged on the sliding rod.

Furthermore, the limiting structure is a limiting long hole groove arranged on the sliding rod along the length direction of the sliding rod; the sliding sleeve is a rod body and is arranged in the limiting long hole groove, the rod body reciprocates along the limiting long hole groove, the limiting long hole groove is used for limiting the movement distance of the sliding ring on the sliding rod, the ring is a notch ring with two open ends, one open end of the notch ring is connected with one end of the rod body, and the other open end of the notch ring is connected with the other end of the rod body.

Furthermore, the limiting structure is a convex point or an annular bulge and is arranged on one side of the sliding rod, which is close to the ring opening head; the sliding sleeve is a sleeve and is sleeved on the sliding rod between the limiting structure and the hook, the limiting structure is used for limiting the movement distance of the sliding ring on the sliding rod, the ring is a notched ring with two open ends, and the two open ends of the notched ring are hinged with the sleeve through a rotating shaft.

Furthermore, the limiting structure is an open ring head with the diameter larger than that of the rod body; the sliding sleeve is a sleeve and is sleeved on the sliding rod between the limiting structure and the hook, the limiting structure is used for limiting the movement distance of the sliding ring on the sliding rod, the ring is a notched ring with two open ends, and the two open ends of the notched ring are hinged with the sleeve through a rotating shaft.

Furthermore, the ring opening head is a flat screwdriver head.

The key ring has the advantages that when a key needs to be hung in the key ring, the ring-opening head at the end part of the sliding rod can be wedged into the inter-ring gap of the key ring, so that the inter-ring gap of the key ring is enlarged, the key can be hung into the opening through the inter-ring gap more easily, the condition that fingers are injured by scratching the key ring with nails is avoided, in addition, when a screwdriver is needed, the sliding ring can be unscrewed towards one side of the rod body and pushed to one end of the hook, the ring-opening head becomes a screwdriver, and the aim that one key ring has multiple functions can be directly achieved.
