The novel alpenstock inner lock provided by the utility model has the advantages of simple structure, labor-saving assembly, convenience for maintenance, low cost, light weight and reliability in locking; the retractable length of an alpenstock piece with the novel inner lock structure provided by the utility model is rapid to lock.

Description

A kind of Novel alpenstock internal lock

Technical field

The utility model relates to a kind of Novel alpenstock internal lock.

Background technique

Common alpin-stock all has telescopic member structure, can adjust according to actual needs elongating or shortening of rod member, and the height of rod member or shortening be so long as innerly be locked into row locking, at present the main fastening system of imitated external product of the interior lock construction of home sale, the assembly of existing internal lock is comparatively complicated, bulky, cost of labor is high, lacks innovation, locking intensity is limited, after parts damages occurring again, whole internal lock just needs to change, and has increased cost.

The model utility content

The shortcomings such as technical problem to be solved in the utility model is to provide a kind of Novel alpenstock internal lock, overcomes existing internal lock construction cost high, and assembly is comparatively complicated, and locking intensity is limited.

The technological scheme that the utility model solves the problems of the technologies described above is as follows: a kind of Novel alpenstock internal lock, be arranged in the telescoping rod of alpin-stock, comprise: connecting rod and expansion set, connecting rod is comprised of pedestal and screw rod, the interior boom end of pedestal and telescoping rod is fixed, screw rod one end and pedestal are fixed, the other end is inserted in expansion set, expansion set is the conical tube structure, the expansion set outer surface is provided with several openings, the top that described screw rod inserts the expansion set end has aperture, the inwall of described aperture is provided with the internal thread that the outside thread with hex head bolt is complementary, copper insert is the little hollow circuit cylinder body structure of the large middle external diameter of two ends external diameter, the inwall of described copper insert is provided with the internal thread that the outside thread with screw rod is complementary, described copper insert advances and is fixed on (motorization assembly in expansion set from the little external diameter side pressure of expansion set, with press, compress into expansion set), described screw rod is inserted in expansion set from the large external diameter end of expansion set, described copper insert is connected with screw flight, described hex head bolt is threaded with the aperture at screw rod top.

On the basis of technique scheme, the utility model can also be done following improvement.

Further, the outer wall of two large external diameter ends of described copper insert is provided with the vertical line parallel with copper insert diameter of axle direction.

Further, described expansion set outer surface is provided with 2 openings, and described 2 openings are symmetrical arranged centered by the center of circle of expansion set, and described opening direction is that described opening length is 2/3 of expansion set total length from the large external diameter end of expansion set to little external diameter end.

The beneficial effect that adopts this step is the opening that lower half portion no longer is set, and makes locking more firm, and the operation of also having saved original this opening, improved working efficiency, reduced cost.

Further, described screw rod is cast steel material.

Further, described expansion set is nylon material.

The beneficial effects of the utility model are:

A kind of Novel alpenstock internal lock of the utility model, simple in structure, assemble laborsavingly, be convenient to maintenance, cost is low, and quality is light, and locking is reliable, and efficiency is high, and the collapsing length locking of alpin-stock rod member with this novel interior lock construction is more quick.
