Description

  The present invention relates to a daily necessities technical field, and particularly to a length-adjustable folding stick.

The walking stick is mainly used to assist pedestrians. Since different users have different heights, there are different types of walking sticks that can be folded and stretched on the market. It can be folded and picked up and carried, and it can accommodate people of different heights by adjusting the length used by the stick as needed.
To adjust the contraction orientation of a conventional stick, the second housing is inserted into the bore of the first housing, and an elastic localization button is installed radially outward on the second housing. A stereotaxic hole of different height is installed on the top, and when it is inserted into the second housing, the stereotaxic button projects and localizes, realizing long and short expansion and contraction. Multi-stage frames connected to each other must be matched when used between each other.
In other words, it must not be shaken at the connection of each step. For this reason, an O-ring is installed on the insertion end of the second housing, a pickup head is installed on the outer periphery of the insertion end of the first housing, and the outer periphery of the corresponding portion of the second housing is tightened and pressed. Yes (shown in Patent Document 1 as an example).

  The problem to be solved is that, in use, the range of the insertion end of the second housing is very narrow, so that it is very inconvenient because it requires elastic drawstrings, arc chamfering and the like.

In the present invention, the walking stick is formed by connecting two or more stages of the casings, the elastic bodies are maintained between the casings, and the upper end of the stick has a grip. The chassis connected to the grip is divided into a first chassis and a second chassis, the grip is connected to the upper end of the first chassis, and the second chassis is connected by an elastic pull string. The first and second housings are stretched and fitted to adjust the length, and a radially outwardly projecting elastic localization button is installed on the fitting end of the second housing. The localization holes of different heights are installed on the peripheral wall of the first casing, and when the second casing is inserted, the convex portion of the localization button is engaged.
A collecting head is installed on the outer periphery of the fitting end portion of the first housing, and the outer periphery of the corresponding portion of the second housing is collected, compressed by sandwiching, and among the housings connected to each other behind the second housing. A cylindrical step is installed at the connecting end of each housing, the cylindrical step is inserted into the bore of another housing, and a step is formed at the root of the cylindrical step and supported by the end surface of the other housing. The most important feature is the installation of an O-ring on the cylindrical stage.

The length-adjustable folding stick of the present invention stops the installation of the O-ring on the fitting end of the second housing, and directly collects it on the outer periphery of the corresponding part of the second housing by the collecting head on the first housing. Compress and clamp, strengthen the connection, and connect more firmly.
In addition, the manufacturing cost was reduced and the structure was simplified. Of the connecting bodies behind the second casing, the O-shaped ring increases the tightness of the fitting between the two stages, is less likely to shake, the pickup head increases the connection, and the connection is more stable and strong. There is an advantage of doing.

The second housing is connected by an elastic pull string, and the first housing and the second housing are stretched and fitted to adjust the length, and the second housing is radially arranged on the fitting end of the second housing. Install an outwardly convex elastic localization button. Positioning holes with different heights are installed on the peripheral wall of the first housing, and when the second housing is inserted, it engages with the convex portion of the positioning button to adjust the expansion and contraction of the length. A pick-up head is installed on the outer periphery of the fitting end of the first housing, and the inner hole at one end of the pick-up head has a small mouth and a large inside, and a screw pattern is placed on the conical surface. A screw pattern that meshes with the screw pattern on the pick-up head is installed on the outer periphery of the end of the first housing, and several incision tanks along the axial direction are installed on the screw pattern.
The pick-up head meshes with the screw crest on the outer periphery of the first housing end with a screw crest, rotates and contracts the inner periphery of the first housing end, collects the outer periphery of the corresponding part of the second housing, and compresses and compresses it. Of the mutually connected casings behind the second casing, a cylindrical step is installed at the connecting end of each casing, the cylindrical step is fitted into the bore of another casing, and the root of the cylindrical step A step is formed on the support and supported by the end face of another housing, and an O-shaped ring is installed on the cylindrical step.

  The localization button of the second housing has a cone-shaped localization stage, and is inserted into and engaged with the localization hole on the first chassis from the localization stage, and the outer diameter of the cone-shaped localization stage gradually increases from the outside to the inside. And the maximum outer diameter of the localization stage is larger than the diameter of the localization hole on the first housing.

  The pick-up head is manufactured from a plastic material and has expansion and contraction properties. The pick-up head picks up the outer periphery of the corresponding portion of the second housing, and compresses and compresses it, thereby strengthening the connection and further connecting.

  The connection between the bodies of the sticks is a cylindrical connection, that is, a columnar stage is installed at the connection end of one of the interconnected bodies.
