Description

Telescopic rod limit structure

This creation is about a limit structure; in particular, it relates to the limit structure of a telescopic rod of a card-limited telescopic rod.

According to the conventional phthalocyanine, the main body comprises an outer tube and a plurality of inner tubes arranged in a tapered shape. The inner tube is connected with a cutter at the innermost side, and the inner tube is elongated to a predetermined height during use. Then use the top tool to remove the greens.

However, in the conventional scorpion scorpion, between the inner tube and the inner tube, the diameter of the bottom portion of the inner tube which is mainly through the inner side is larger than the diameter of the top portion of the outer inner tube, thereby generating the locking limit function, and the inner tube can be fixed. The position, however, the top tool of the jingzi 有一 has a weight, a use time, often causes the inner inner tube to push down due to gravity, at this time, the inner inner tube will be unable to be stuck to the outer inner tube. The action of folding, together with the weight of the cutter, often causes the inner tube to collapse downwards, which will cause a great impact force, which will cause harm to the artemisia or the user.

The present invention is a limit structure of a telescopic rod, which comprises an outer tube, the top of the outer tube is provided with a screwing unit, at least two inner tubes, and the inner tube is sleeved in the outer tube The screwing unit can be screwed to limit the inner tubes, the inner tubes are tapered, and the inner inner tube The bottom diameter is larger than the top diameter of the outer inner tube, and the at least one limit plug is disposed on the top of the outer inner tube. The top end of the limit plug is internally provided with a stop portion. The card can be limited to the inner inner tube.

The limit structure of the telescopic rod provided by the creation, the stop portion of the limit plug can have a good limit fixing effect on the inner inner tube, and the limit stopper is used to strengthen the limit position, thereby avoiding the inner tube use. When dropped, it can increase the safety of use and the service life of the appliance.

Figure 1 is an exploded perspective view of a preferred embodiment of the present invention.

Figure 2 is a schematic cross-sectional view of a preferred embodiment of the present invention.

Please refer to the figure, which is a perspective view and a perspective exploded view of a preferred embodiment of the limit structure of the creation of the telescopic rod, which mainly includes an outer tube 10, and the top of the outer tube 10 is provided. There is a screwing unit 11; two inner tubes 20, the inner tube sleeves are sleeved in the outer tube, and the screwing unit can be screwed to limit the inner tubes, the inner tubes are tapered, inner side The bottom diameter of the inner tube 20 is larger than the top diameter of the outer inner tube 20, and a cutter 21 is attached to the top end of the innermost inner tube 20; a limit plug 30 is disposed on the top of the outer inner tube 20, A stopper portion 31 is disposed inside the top end of the stopper 30, and the stopper portion 31 can be restrained to the bottom of the inner inner tube 20. In addition, in order to increase the frictional force, the frictional portion 32 is convexly disposed on the blocking portion 31, and the ridges 33 are convexly formed on the outer circumferential loop of the limiting plug 30.

In order to further understand the characteristics of this creation, the use of the means of technology and the expected results, the use of this creation is described, I believe that this can be a deeper and more specific understanding of this creation, as described below; 2, when the height of the cutter 21 is to be adjusted, the innermost inner tube 20 is first pulled upward, and when the inner inner tube 20 reaches the highest position, the bottom of the inner inner tube 20 is restricted to the outer side. At the top of the tube 20, at the same time, the blocking portion 31 of the limiting plug 30 is locked to the outer circumference of the inner inner tube 20, and the blocking portion 31 and the inner inner tube 20 can be increased by the friction pattern 32. The frictional force of the contact, thereby increasing the clamping force between the inner tubes 20, so that the cutter 21 is not easily dropped during use, and the accident and the damage of the appliance can be reduced, and the outer side of the stopper 30 is further The ridge 33 can help the user to conveniently move when taking out. When the height adjustment of the inner tube 20 is completed, the position of the inner tube 20 is locked by the screwing unit 11, and the screw unit 11 of the outer tube 10 can be The inner tube 20 is adjusted to be screwed when positioning, so that the inner tube 20 Tube 20 can be restrained.

In summary, when Zhiben's creation has industrial applicability and progress, and this creation is not found in any publication, it is also novel. When it meets the requirements of the Patent Law, it proposes a new type of patent application according to law. The quasi-patent is a prayer.

Only the above-mentioned ones are only one of the feasible embodiments of this creation. When it is not possible to limit the scope of the implementation of this creation; that is, the equal changes and modifications made by Dafan according to the scope of patent application for this creation should still belong to this new type of patent. Within the scope of coverage.
