Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely below, and it should be apparent that the described embodiments are only some embodiments of the present invention, but not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

Referring to fig. 1-4, a handrail retractable head for magnetic buckling is shown, which includes a top cover 1, a speed reduction mechanism 2, an upper cover 3, a spring box 5, a center shaft 4, a first upright post 6 and a second upright post, wherein the top cover 1, the speed reduction mechanism 2 and the upper cover 3 are sequentially arranged at the upper end of the center shaft 4 from top to bottom, the spring box 5 is arranged at the lower end of the center shaft 4, the first upright post 6 and the second upright post are arranged around the outer side of the center shaft 4, the upper cover 3 and the spring box 5 are fixedly connected by the first upright post 6 and the second upright post, a first magnet 61 is arranged at the outer side of the first upright post 6, a through hole is arranged on the second upright post, a retractable belt is wound on the center shaft 4, the retractable belt penetrates out from the through hole on the second upright post, a handle 7 is connected to the end of the retractable belt, a second magnet 71 is arranged on the handle 7, the first magnet 61 and the second magnet 71 are magnetically attracted when they correspond to each other.

The speed reducing mechanism 2 comprises a shell 21, a friction plate 25, a planet carrier 24 with an inner ratchet wheel, a pawl 23 and a limiting ring 22, wherein the pawl 23 is arranged on the limiting ring 22, the friction plate 25 is fixed on the planet carrier 24, the pawl 23 is matched with the inner ratchet wheel of the planet carrier 24, and the limiting ring 22 and the planet carrier 24 are coaxially and rotatably fixed in the shell 21. The limiting ring 22 is clamped with the middle shaft 4. When an operator needs to connect one telescopic handrail to another telescopic handrail, the operator pulls the telescopic belt through the handle 7, the telescopic belt drives the central shaft 4 to rotate, the central shaft 4 drives the limit ring 22 to rotate, as shown in fig. 3, the limit ring 22 rotates clockwise, the pawl 23 does not drive the inner ratchet wheel of the planet carrier 24 to rotate, the friction plate 25 on the planet carrier 24 is stationary, no friction force is generated, and the operator buckles the handle to the lug of the upright post 6 of another telescopic handrail; after an operator unlocks the handles 7 which are buckled with the two telescopic railings, the coiled sheet spring in the spring box 5 can reset to drive the middle shaft 4 to rotate, the middle shaft 4 can drive the limiting ring 22 to rotate, as shown in fig. 3, the limiting ring 22 rotates anticlockwise, the pawl 23 is inserted into the inner ratchet wheel of the planet support 24 under the action of centrifugal motion, the pawl 23 drives the planet support 24 to rotate, the friction sheet 25 on the planet support 24 generates centrifugal motion, the friction sheet 25 rubs with the inner wall of the shell 21 to generate resistance, and the rotating speed of the middle shaft 4 is reduced, so that the recovery speed of the telescopic belt is reduced, and the telescopic belt is prevented from being recovered too fast to cut the operator. The clockwise and counterclockwise rotation directions are only used to illustrate the movement of the speed reducing mechanism 2, and in practical cases, the rotation directions do not need to be set.

The quantity of first stand is 3, the quantity of second stand is 1, first stand 6 and second stand are circumference equidistance and set up outside the top cap.

The number of the friction plates 25 is at least 2, preferably 3, and the friction plates are arranged in a circumferential equidistant manner; therefore, the friction plate 25 and the inner wall of the shell 21 generate uniform friction force, the friction plate 25 is damaged uniformly, and the service life is longer. The centrifugal movement of the friction plate 25 is smoother.

The first magnet 61 is embedded in the first upright 6 and the second magnet 71 is embedded in the handle 7.

The first magnet 61 and the second magnet 71 are fixed to the first column 6 and the handle 7 by bolts. It is easy to replace the first magnet 61 and the second magnet 71.

The first magnet 61 and the second magnet 71 are permanent magnets. The first magnet 61 and the second magnet 71 are made of one of rare earth permanent magnet materials, sintered ferrite, rubber magnet, alnico or samarium cobalt.

In actual operation, when one telescopic handrail needs to be connected with another telescopic handrail, the handle 7 on one telescopic head of the handrails is directly pulled to be close to the other telescopic head of the handrails, the second magnet 71 on the handle 7 corresponds to the first magnet 61 on the first upright post 6 on the other telescopic head of the handrails, the two magnets are attached to each other for magnetic adsorption, and the telescopic belt can be installed completely; the second magnet 71 on the handle is dislocated with the first magnet 61 on the first upright post 6 on the other telescopic head of the railing, so that the telescopic belt can be detached.

The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
