Description

A kind of key chain

Technical field

The utility model relates to daily necessities field more particularly to a kind of key chains.

Background technique

Key be people it is the most used in daily life be also most important carry-on articles, but the use of key chain Range is relatively simple, but is the object of outgoing indispensability, it is necessary to carry, traditional key chain is only used for hanging key, thus passes Its is in the form of a single for the key chain of system, function is also relatively simple, and without other additional functions, narrow application range.

Utility model content

The technical problem to be solved by the utility model is to provide a kind of key chains, to solve the above problems.

The technical solution that the utility model solves above-mentioned technical problem is as follows: including ontology, connecting column, key ring and extension Hook, ontology are equipped with scale strip, and scale strip is equipped with the pointer that can slide up and down, spring, spring are additionally provided on the inside of scale strip Upper end be connected with ontology, lower end is connected with pointer；The lower end of ontology is arranged in connecting column, and connecting column includes portable pillar, The upper end of portable pillar stretches to body interior and is fixedly connected with the lower end of pointer, and the lower end of portable pillar is connected with hook.

The beneficial effects of the utility model are: setting spring and hook make key so that the function of key chain is no longer single Key ring can carrying keys, moreover it is possible to and it is used as weight beam scale and uses, article is hung on hook, weight of object can be measured, it is real It is stronger with property.

Further, connecting column further includes fixed column, fixed column is set in portable pillar, under the upper end and ontology of fixed column End is fixedly connected.

Further, the lower end of fixed column is connected with key ring, the junction of key ring and fixed column is equipped with torsional spring.

Further, the size of hook is less than the size of key ring.

The beneficial effect of above-mentioned further scheme is: setting key ring makes key chain when not measuring weight, can hang The daily small tools such as key, nail clipper are hung, user is avoided and directly tool is suspended on hook, spring is caused to be drawn Power, so that influencing the subsequent precision measured using scale generates error, the size of key ring is greater than the size of hook, while torsion is arranged Spring, key ring self-return is linked up with to the same plane of hook so as to protect after aloowing weighing.

Further, ontology is equipped with a level meter.

The beneficial effect of above-mentioned further scheme is: can guarantee that key chain is in a vertical state when weighing, and guarantees measurement Accuracy.
