Description

Technical field:

[0001] The utility model relates to the technical field of walking aid equipment, and more specifically to a walking aid handrail rubber sleeve installation structure. Background technology:

[0002] The existing walker generally includes two bent side brackets, and an anti-slip cover is provided on the upper transverse rod of the two side brackets to facilitate hand holding. However, the existing anti-slip cover is directly covered on the upper transverse rod, and is fixed by clamping. Therefore, in the initial use, the anti-slip cover will not slide forward and backward along the upper transverse rod, and the use effect is very good;

[0003] However, after long-term use, since the upper horizontal rod is a metal part, thermal expansion and contraction as well as aging and deformation of the anti-slip cover make it difficult for the two to be stuck together. At this time, the anti-slip cover will move back and forth along the upper horizontal rod, which will affect the user's use. Utility model content:

[0004] The purpose of the utility model is to overcome the deficiencies of the prior art and provide a walker handrail rubber sleeve installation structure, which realizes positioning by inserting a positioning rod in the elastic handrail rubber sleeve into a corresponding vertical through hole formed in the middle of the top surface of the upper transverse tube portion, so that the elastic handrail rubber sleeve is firmly fixed to the upper transverse tube portion and will not slide, thereby ensuring its normal use.

[0005] The solution of the utility model to solve the technical problem is:

[0006] A walker handrail rubber sleeve installation structure comprises an upper transverse tube portion of a side support tube, an elastic handrail rubber sleeve is clamped in the middle of the upper transverse tube portion, a plurality of positioning rods are provided on the top surface of the middle through hole of the elastic handrail rubber sleeve, and the positioning rods are inserted into the vertical through hole extending downward formed in the middle of the top surface of the upper transverse tube portion.

[0007] A sleeve portion is clamped in the vertical through hole, the top of which extends out of the top surface of the upper transverse tube portion and is formed with a radially extending edge, the bottom surface of which is pressed against the top surface of the upper transverse tube portion.

[0008] The positioning rod is clamped in the sleeve body.

[0009] The elastic armrest rubber sleeve is a sleeve with a C-shaped cross-section, and a downwardly extending through groove is formed on the bottom surface of the central through hole, and the front and rear ends of the through groove extend out of the front and rear ends of the elastic armrest rubber sleeve. The upper transverse tube is located in the central through hole, and the outer side wall of the upper transverse tube is pressed against the inner side wall of the central through hole.

[0010] The outstanding effects of the utility model are:

[0011] It achieves positioning by inserting a positioning rod in the elastic handrail rubber sleeve into a corresponding vertical through hole formed in the middle of the top surface of the upper horizontal tube, so that the elastic handrail rubber sleeve is firmly fixed to the upper horizontal tube and will not slide, thereby ensuring its normal use. Description of the drawings:

[0012] Figure 1 It is a partial structural schematic diagram of the utility model;

[0013] Figure 2 It is a partial cross-sectional view of the utility model. Specific implementation method:

[0014] For example, see Figure 1 to Figure 2 As shown, a walking aid handrail rubber sleeve installation structure comprises an upper transverse tube portion 10 of a side support tube, an elastic handrail rubber sleeve 20 is clamped in the middle of the upper transverse tube portion 10, and a plurality of positioning rods 21 are provided on the top surface of the middle through hole of the elastic handrail rubber sleeve 20, which can be fixed in the following manner:

[0015] The upper end of the positioning rod 21 is screwed into a corresponding screw hole formed on the top surface of the middle through hole of the elastic handrail rubber sleeve 20;

[0016] Alternatively, the upper end of the positioning rod 21 is molded or bonded to the top surface of the middle through hole of the elastic handrail rubber sleeve 20 .

[0017] Furthermore, the positioning rod 21 is inserted into a vertical through hole 11 formed in the middle of the top surface of the upper transverse tube portion 10 and extending downward.

[0018] Furthermore, a sleeve portion 30 is clamped in the vertical through hole 11, the top of the sleeve portion 30 extends out of the top surface of the upper transverse tube portion 10 and is formed with a radially extending edge 31, and the bottom surface of the radially extending edge 31 is pressed against the top surface of the upper transverse tube portion 10. A radially extending portion is formed on the top outer side wall of the positioning rod 21, which is pressed against the top surface of the corresponding radially extending edge 31.

[0019] Furthermore, the positioning rod 21 is clamped in the sleeve body 30 .

[0020] Furthermore, the elastic armrest rubber sleeve 20 is a sleeve with a C-shaped cross-section, and a downwardly extending through groove is formed on the bottom surface of the central through hole, and the front and rear ends of the through groove extend out of the front and rear ends of the elastic armrest rubber sleeve 20, and the upper transverse tube portion 10 is located in the central through hole, and the outer side wall of the upper transverse tube portion 10 is pressed against the inner side wall of the central through hole.

[0021] Furthermore, a toothed portion 210 is formed on the inner side wall of the elastic handrail rubber sleeve 20, and the toothed portion 210 is pressed against the outer side wall of the upper transverse tube portion 10. The toothed portion 210 further increases the friction between the elastic handrail rubber sleeve 20 and the upper transverse tube portion 10, thereby improving the clamping effect thereof.

[0022] Furthermore, a plurality of anti-skid convex points 1 are formed on the outer side wall of the elastic armrest rubber sleeve 20. The anti-skid convex points 1 can increase the friction between the hand and the elastic armrest rubber sleeve 20 and the gripping effect.

[0023] When this embodiment is in use, the positioning rod 21 provided on the elastic handrail rubber sleeve 20 is inserted into the corresponding vertical through hole 11 to achieve positioning, so that the elastic handrail rubber sleeve 20 and the upper horizontal tube portion 10 will not move relative to each other, thereby ensuring the clamping effect.

[0024] A sleeve portion 30 is clamped in the vertical through hole 11, and the positioning rod 21 is clamped in the sleeve portion 30. The sleeve portion 30 can reduce the shear force between the positioning rod 21 and the vertical through hole 11, greatly reducing the probability of the positioning rod 21 breaking, and ensuring the positioning and fixing effect.
