Description

Crutches positioning bead structure

The present invention relates to a positioning bead structure of a crutches, in particular, the positioning bead and the positioning of the crutches can abut against each other at a flat end, thereby avoiding the positioning perforation being subjected to extrusion deformation, thereby improving the service life of the structure.

According to the conventional crutches structure with telescopic adjustment, as shown in the figures 6, 7, and 8, the crutches 30 are slidably adjustable to be provided with an inner tube 31 and an outer tube 32. A positioning hole 311 is disposed, and the wall of the outer tube 32 is arranged with a plurality of limiting holes 321 corresponding to the positioning holes 311, and a spring fastener 33 is assembled into the inner tube 31 through the elastic fastener. After passing through the positioning hole 311, the positioning hole 311 is fixedly locked with one of the limiting holes 321 to complete the positioning state of the crutches 30 after the telescopic adjustment. However, the conventional positioning hole 311 of the crutches 30 in the inner and outer tubes 31 and 32 and The limiting holes 321 are all in the shape of a circular hole, and the elastic fasteners 33 are also formed into a cylindrical shape. When the user holds the walking stick 30 and supports the ground to assist walking, the force will first fall on the outer tube 32 and then through the bullet. The buckle 33 is transferred to the inner tube 31 so that the limiting hole 321 of the outer tube 32 abuts against the end edge of the elastic member 33, and the circular hole and the cylinder abut against each other, resulting in the limiting hole. The contact point between the 321 and the elastic fastener 33 is only one end, and the strength and hardness of the elastic fastener 33 are higher than the inner and outer tubes 31 and 32, and the limiting hole is caused by the limiting hole. The 321 is deformed by the reaction force of the elastic fastener 33, so that the aperture of the limiting hole 321 is enlarged to increase the gap with the elastic fastener 33, which affects the accuracy of the positioning of the elastic buckle 33, and the inner tube 31 The positioning hole 311 will also be The extrusion deformation causes the periphery of the positioning hole 311 to bulge and rub the inner wall of the outer tube 32, which not only affects the smoothness of the telescopic adjustment of the crutches 30, but also causes the gap between the inner and outer tubes 31 and 32 to be increased by the wear of the tube wall. Reducing the stability of the use of the structure is necessary for improvement.

In view of this, the creator has been engaged in the manufacturing development and design experience of related products for many years. After detailed design and careful evaluation, the author has finally achieved a practical and practical creation.

The technical problem to be solved by the present invention is to provide a positioning bead structure of the crutches for the above-mentioned defects existing in the prior art.

The above-mentioned structure includes a stick body, the stick body is slidably adjustablely provided with an inner tube and an outer tube, the inner tube tube wall is provided with a positioning hole, and a latching bead body is disposed through the positioning hole, and the The outer tube wall is arranged with a plurality of limiting holes corresponding to the positioning holes, wherein the positioning holes and the upper ends of the inner diameters of the limiting holes form a flat portion, and the buckled bead body The upper end of the outer diameter also correspondingly forms an abutting plane.

Preferably, the buckle body has a blocking portion and a through portion, the blocking portion is larger than the positioning hole and is confined in the inner tube, and the through portion is protruded from the positioning hole and the Outside the limiting hole, the abutting plane is formed at the upper end of the outer diameter.

Preferably, the positioning hole and the limiting holes are all in the shape of one hole, and the buckle bead body also forms a one-sided cylinder, and the front end of the protruding portion of the buckled bead body forms a curved end.

Preferably, the surface of the buckle portion of the buckle bead body is provided with a longitudinal groove, and the longitudinal groove is further provided with a through hole.

Preferably, the buckle bead system is matched with a V-shaped elastic member, and one of the elastic members The end is bent to form a plunger, and the insertion hole is formed through the insertion hole of the stopper.

Compared with the effect of the prior art: the body of the pen of the present invention forms a crutches structure for the user to use, because the positioning hole of the inner tube and the limiting hole of the outer tube can equally abut the spring buckle with the flat portion The abutting surface of the bead body enables the supporting force channel to be dispersed, so as to prevent the positioning hole and the limiting hole from being crushed and deformed by the reaction force of the buckle bead body, ensuring the integrity of the positioning hole and the limiting hole, and improving the positioning. The accuracy of the positioning of the hole and the limiting hole and the buckle of the buckle body prevents the inner diameter of the outer tube from being scratched and worn by the deformation of the inner tube, thereby increasing the stability of the structure and helping to extend the crutches. For the service life, there will be practical enhancers.

In order to enable your review committee to have a better understanding and understanding of the purpose, characteristics and efficacy of this creation, please refer to the following [Simplified Description of the Drawings] for details: First, please refer to Figures 1 and 2 below. A positioning bead structure of a cane, comprising a The stick body 10 and a latching bead body 20 are slidably adjustablely provided with an inner tube 11 and an outer tube 12, the inner tube 11 is provided with a positioning hole 111 in the tube wall, and the outer tube 12 is provided with a positioning hole 111 A plurality of limiting holes 121 are formed in the order of the positioning holes 111. The positioning holes 111 and the limiting holes 121 are all in the shape of one hole, and are formed at the upper ends of the inner diameters of the positioning holes 111 and the limiting holes 121. a flat portion 112, 122, wherein the latch body 20 has a stop portion 21 and a through portion 22, and the stop portion 21 is larger than the positioning hole 111 and is confined in the inner tube 11, The surface of the blocking portion 21 is provided with a longitudinal groove 211. The longitudinal groove 211 is further provided with a through hole 212. The through portion 22 is protruded from the positioning hole 111 and the limiting hole 121. The upper end of the outer diameter of the through portion 22 forms an abutting surface 221, and the front end of the through portion 22 forms a curved end 222, and the elastic bead body 20 is coupled with a V-shaped elastic member 23, the elasticity One end of the piece 23 is bent to form a plunger 231, and the insertion hole 231 is inserted through the through hole 212 of the stopper portion 21 to form a positioning.

The structure of the structure, as shown in the figures 1, 2, 3, and 4, the buckled bead body 20 is assembled into the inner tube 11 with the elastic member 23, and the elastic member 23 is inserted into the end of the inner tube 11. The 231 is disposed in the through hole 212 of the stopping portion 21, and the elastic member 23 is restricted by the longitudinal groove 211, and the elastic bead body 20 and the elastic member 23 are assembled into the inner tube 11 by using the elastic member. The protruding portion 22 of the buckled bead body 20 is protruded from the positioning hole 111, and the stopper portion 21 is abutted against the inner wall of the inner tube 11 to form a limit, and the outer tube 12 is threaded over the inner tube. 11 outer diameter, and can be displaced along the inner tube 11 to reach the length of the telescopic adjustment, and then one of the limiting holes 121 is positioned by the buckled bead body 20 to complete the installation of the present invention.

The state in which the structure is actually used, as shown in Figures 1, 3, and 4, the stick body 10 is adjusted to the inner and outer tubes 11, 12 by the length of the inner and outer tubes 11, 12 due to the inner and outer portions.
