Description

Telescopic tube structure

This creation is about a telescopic rod technology, especially a telescopic tube structure that can improve stability.

The design of the telescopic tube can be applied to various objects to extend the current length of the object, which is helpful for the user to grip objects with a long distance or perform other functions on the objects.

In the case of pruning shears, the device of the telescopic tube is mostly installed on the handle of the pruning shears, so that the handle can be extended and retracted, allowing the user to operate the pruning shears to extend to a farther position, so that the user can cut flowers and branches Wait for work.

Please refer to the first figure, the design of the telescopic grip 92 of the pruning shears 90 generally only uses an outer tube 922 and an inner tube 924 to be sleeved together, because the diameter of the inner tube 924 will be smaller than the diameter of the outer tube 922 Therefore, the inner tube 924 can move freely in and out of the outer tube 922, thereby extending the length of the telescopic grip 92, so that the pruning shears 90 can cut objects at a greater distance, or make the operation more convenient.

However, during mass production of the outer tube 922 and the inner tube 924, the dimensions of each part cannot be exactly the same. As a result, when the outer tube 922 and the inner tube 924 are installed together, the outer tube 922 and the inner tube 924 cannot be completely matched, which is easy to produce Due to slight tolerances, when the inner tube 924 expands and contracts with the outer tube 922, the inner tube 924 is prone to sway, which makes the overall design unstable, and it is relatively unstable for users. For pruning shears 90, the application may make the user unstable when cutting objects, and cause the cut objects to deviate from the user's originally intended design.

In view of this, the author proposes a telescopic tube structure to effectively overcome the above-mentioned problems in view of the lack of the above-mentioned conventional technology.

The main purpose of this creation is to provide a telescopic tube structure that can compensate for the tolerance between the first tube body and the second tube body, reduce sloshing during expansion and contraction, and improve the stability of the telescopic tube structure.

Another purpose of this creation is to provide a telescopic tube structure, which has a simple structure, can relatively improve the production efficiency, and effectively reduce the production cost.

The buckle of the kit further includes a protruding block snapped into the groove of the second tube body, and the protruding block is further provided with a bevel block, and a sliding member is further provided on the bevel block. The sliding member can slide on the bevel block. When the sliding member slides toward the top of the inclined surface block, the sliding member can bear against the second tube body, so that the kit is fixed on the second tube body.

A groove is further provided on the inclined surface block, and a blocking concave portion is further provided on both side walls of the groove; a blocking convex portion is provided on both sides of the sliding member respectively, when the sliding member slides toward the top of the inclined surface block, the two blocking convex portions can be correspondingly engaged In the two blocking recesses of the groove, the slider can be fixed on the top of the inclined block.
