TWM600560U - Side-operating buckle - Google Patents

Abstract

A side buckle includes a female buckle, a base and a plug buckle. The female buckle and the base are rectangular, trapezoidal or flat oval metal tubes, which are cut by laser. The buckle is formed by plastic molding and assembled on the base. The two constitute a male buckle and can be detachably locked with the female buckle. The side opening buckle composed in this way only needs to prepare a plastic mold for producing the buckle, which not only reduces the mold cost, but also directly reduces the cost of the product. Moreover, because the core component is cut from a metal tube, there is a side opening buckle. At the same time that it has sufficient strength, it also achieves a lightweight effect.

Description

Side buckle

This creation is about a kind of buckle, especially a side buckle that unbuckles from the side.

As we all know, webbing has countless applications. Common examples include restraint devices for pets (such as collars, walking belts, etc.), baby carriers, backpacks, hiking bags, helmets, sandals, life jackets, cargo and passenger restraints, etc. , And has achieved great success in the market. As for the webbing so that it can be so widely and successfully used in all kinds of goods, it depends on the buckle. Among all kinds of buckles, the side release buckle that releases the lock from the side (Side Release Buckle) is the most commonly used.

The conventional side buckles are available in plastic and metal according to their materials. Among them, the plastic side buckle is composed of a male buckle and a female buckle, which has the advantages of fewer parts, cheapness and light weight, but is easy to wear and has relatively low strength. The metal side buckle requires more components. Except that the return spring can be formed of metal or plastic, the rest of the components are all zinc alloy die-cast products. Therefore, compared to the plastic side buckle, although the metal side buckle has higher strength, it is costly and heavy.

However, whether it is plastic injection molding or die-casting of the side release button, it needs to be produced with a mold, and a set of molds must be prepared for side release buttons of different specifications. The mold is not only expensive, but also has a limited lifespan.

This creation is made to solve the above problems, and its purpose is to provide a This kind of side-opening buckle can reduce mold costs, reduce production costs, and achieve lightweight effects while having sufficient strength.

The side-opening buckle that specifically realizes this creation includes a female buckle, a base and a plug buckle. The female buckle has a slot, the slot is defined by an upper groove wall, a lower groove wall, a left groove wall and a right groove wall, the upper groove wall or the front of the lower groove wall has two buckles For the stop part, the left and right groove walls respectively have an opening extending to the upper and lower groove walls and communicating with the slot. The base includes a seat, and the seat has a cavity defined by a top wall, a bottom wall, a left side wall and a right side wall. The buckle includes a root, and a left arm and a right arm respectively extending forward from two sides of the root. The root is sleeved into the cavity of the base so that the buckle and The bases are combined to form a male buckle, the middle sections of the left and right insert arms respectively constitute an operating part, the free ends each form a buckling part, and there is an escape port between the two operating parts and the two buckling parts. . When the male buckle is inserted into the slot, the left and right inserting arms are respectively squeezed by the left and right groove walls to accumulate elastic energy, until the two operating parts each face the two openings When the pressure disappears, the left and right inserting arms return to their original state due to the action of elastic force. At the same time, the two buckling parts avoid the two buckling parts at the two escape ports, and reach the two buckles respectively. The fronts of the stop parts are buckled with each other, so that the male buckle and the female buckle are locked together. When pressure is applied to the operating parts of the left and right inserting arms from the openings of the left and right groove walls of the female buckle, the lock can be released to allow the male buckle to be separated from the female buckle.

In a preferred embodiment, the upper groove wall and the lower groove wall of the female buckle each have an upper guide groove and a lower guide groove, and the base extends forward from the front edges of the top and bottom walls. An upper guide and a lower guide, the upper and lower guides respectively engage with the upper and lower guide grooves when the male buckle is inserted into the slot.
