Description

A multi-position telescopic brace

technical field

The utility model relates to the field of accessories for doors and windows, in particular to a multi-position telescopic support.

Background technique

At present, in the field of building doors and windows, window stays have been widely used, but most of the currently used window stays use cross-head screws or slotted screws to adjust the limit, which is extremely inconvenient to operate, and the screws are easy to loosen , The locking force is not strong enough, when the wind is too strong, the window will be closed suddenly, which is easy to damage the window, so it is urgently needed to improve.

Utility model content

The purpose of the utility model is to solve the above-mentioned problems and deficiencies, and provide a convenient, reliable and durable multi-position telescopic support.

The technical scheme of the utility model is achieved in this way.

A multi-position telescopic brace, comprising an outer brace, an inner brace, an inner brace, a frame connecting piece, a fan connecting piece, positioning teeth and rivets, and is characterized in that the outer brace is made of a hollow structure, A number of positioning tooth holes are also made on one side of the outer strut;

The middle parts of the frame connecting piece and the fan connecting piece are respectively bent to form arched bending parts, and connecting holes are respectively provided at the two ends of the frame connecting piece and the fan connecting piece;

The inner support sleeve is set in the outer support rod, the inner support rod is sleeved in the inner support sleeve, one end of the inner support rod protrudes outside the inner support sleeve, and the other end of the inner support rod protrudes from the outer support Outside the rod, the positioning tooth is installed on the inner support sleeve, and the positioning tooth is clamped in the positioning tooth hole;

The bent portion of the frame connecting piece is fixedly installed on one end of the inner strut by a rivet, and the bent portion of the fan connecting piece is fixedly installed on the other end of the inner strut by a rivet.

The utility model adopts the above-mentioned technical scheme, and adjusts the limit position through the mutual cooperation between the positioning tooth and the positioning tooth hole of the outer support rod. product reliability and durability.
