The part of the adjustment button 4 with a locking rod 41 extends into a guide groove 21 opened along the length direction of the support rod 2. The locking rod 41 is locked in a locking groove 22 opened on the inner wall of the guide groove 21 by the elastic element 3.

[0029] That is, the support rod is provided with a guide groove on the side close to the adjusting button, the key tail of the adjusting button extends through the movable sleeve into the guide groove, and can be matched with the two side walls of the guide groove, so that the key tail will not be deflected when the button is moved up and down or stationary, and the two ends of the lock rod can be synchronously moved into the locking groove, so that the lock rod can be kept stable when being locked or moved, and the operability of the height adjustment of the handrail is improved.

[0030] In the embodiment, the adjusting button 4 comprises a lock rod 43 and a key tail 42 connected with each other, the lock rod 43 is elastically connected with the movable sleeve 1 through the elastic member 3 outside the movable sleeve 1, and the key tail 42 is at least partially matched with the gap between the side walls in the guide groove 21 through the movable sleeve 1.

[0031] The key cap is a large-area convex part for facilitating the user to operate with fingers, the key tail is embedded in the inside of the guide groove structure, can drive the lock rod to move, and realizes the linkage unlocking or locking, and the elastic member is arranged between the key cap and the sleeve, so that the lock rod can be kept in the locking groove.

[0032] In the embodiment, the lock rod 41 is arranged on the part of the key tail 42 extending into the guide groove 21, and the movable sleeve 1 is provided with a waist-shaped hole 11 perpendicular to the length direction of the guide groove 21 on the opposite sides, and the two ends of the lock rod 41 are respectively slid in the waist-shaped hole 11.

[0033] The waist-shaped hole provides transverse guide and limiting, the lock rod is clamped into or separated from the locking groove in horizontal sliding, limits the maximum stroke of the button that can be pressed, and ensures that the transverse stroke of the lock rod is enough to separate from the locking groove.

[0034] In the embodiment, the elastic member 3 pushes the lock rod 43 away from the movable sleeve 1, so that the lock rod 41 slides to the locking position at one end of the waist-shaped hole 11 and is clamped against the locking groove 22 along the length direction of the guide groove 21.

[0035] The compression of the elastic member 3 makes the key tail 42 deeply extend into the guide groove 21, and the lock rod 41 slides to the unlocking position at one end of the waist-shaped hole 11 and is separated from the locking groove 22 along the length direction of the guide groove 21.

[0036] In use, the button is pressed, the lock rod moves to the unlocking position at the other end of the waist-shaped hole, is separated from the locking groove, and at the same time, the movable sleeve part can be moved up and down to adjust the height of the handrail; the button is released, the lock rod returns to the locking position in the locking groove under the action of the elastic member, and at the same time, the movable sleeve is limited up and down, and the handrail is fixed.

[0037] In the embodiment, the elastic member 3 can be a spiral spring, one end of the spiral spring is connected with the lock rod 43, and the other end is abutted against the outer wall of the movable sleeve 1.

[0038] The spiral spring has good compression and recovery, is suitable for the quick return requirements of most structure members, and the compression amount is controlled within 4-8 mm.

[0039] In the embodiment, the elastic member 3 can be an arched elastic piece, the vault of the arched elastic piece abuts against the lock rod 43, and the two legs of the arched elastic piece are supported on the outer wall of the movable sleeve 1.

[0040] The arched elastic piece is stamped from metal or composite material, the installation is convenient, the elastic force is uniformly output, and the arched elastic piece is suitable for low-cost products or handrail structures with strict height limitation.

[0041] In the embodiment, the side wall of the guide groove 21 is provided with an adjusting through groove 23, a plurality of locking grooves 22 are distributed on the adjusting through groove 23, and the lock rod 41 can be moved to the positions corresponding to the respective locking grooves 22 along the length direction in the adjusting through groove 23.

[0042] The through groove serves as a slide for the lock rod to move up and down after the lock rod is unlocked, the locking groove is provided on the side of the through groove close to the key, and the shape of the locking groove is a notch similar to the lock rod, so that the lock rod can be prevented from moving along the length direction of the through groove after cooperation.

[0043] In the embodiment, arc-shaped surfaces are arranged between the respective locking grooves 22 for transition.

[0044] The arc-shaped transition alleviates mechanical jamming in the sliding process, improves the user's feeling, and reduces the operation resistance, and is usually designed as a small fillet with a radius greater than the radius of the locking groove, so that the lock rod is smoothly displaced.

[0045] In the embodiment, the support rod 2 is circumferentially provided with a C-shaped hoop 24, and the C-shaped hoop 24 avoids shielding the guide groove 21.

[0046] The C-shaped hoop is used for improving the strength of the hollow guide groove 21 part, so as to ensure that the support rod does not deform to hinder the movement of the lock rod after bearing pressure. The opening of the C-shaped hoop is consistent with the direction of the guide groove, so as to ensure that the movement of the lock rod is not hindered, and the material can be a plastic or metal stamping part fixed by an elastic clamping mode.
