Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1: Please refer to Figures 1-6 The stair handrail connecting device provided by this utility model mainly consists of two connecting parts 3, a rotating part 4, and related auxiliary components. The two connecting parts 3 are used to connect the handrail body 1 and the railing body 2 respectively. The two are connected by the rotating part 4, so that the handrail body 1 and the railing body 2 can rotate relative to each other to adapt to different installation angles and usage requirements.

[0027] The connector 3 specifically includes a plug 5 and a base 6. Both the plug 5 and the base 6 are made of a metal that is not attracted by a magnet, such as aluminum alloy. The bottom of the plug 5 has a rectangular hole, in which a sliding block 7 is installed that can slide up and down. A magnet 8 is installed at the bottom of the sliding block 7. On the inner wall of the rectangular hole, two sliding holes are symmetrically opened, and each sliding hole has a sliding side block 9 that can slide left and right. The two side blocks 9 are connected to the sliding block 7 by a steel wire rope 15. Positioning blocks 10 are installed on the opposite sides of the two side blocks 9. Two fixing plates 11 are also installed in the rectangular hole. Spring plates 12 are installed on the two fixing plates 11, and the two spring plates 12 press against the opposite sides of the two side blocks 9 respectively. The side slider 9 is provided with a restoring force to ensure that the positioning block 10 can be stably extended or retracted. Both sides of the insertion block 5 are provided with through holes for the positioning block 10 to pass through. When the lower slider 7 slides down under the action of external force, the two side sliders 9 can slide inward at the same time through the traction of the wire rope 15, so that the positioning block 10 retracts into the insertion block 5. Because the elastic force of the two spring plates 12 is greater than the overall weight of the lower slider 7 and the magnet 8, when the external force acting on the lower slider 7 is removed, the spring plates 12 can make the two side sliders 9 slide outward at the same time through the elastic force, so that the positioning block 10 extends out from the side of the insertion block 5. At the same time, the lower slider 7 slides upward through the traction of the wire rope 15, and finally abuts against the bottom of the fixing plate 11.

[0028] The base 6 is fixed to the bottom of the insert block 5, and a slot 16 is provided on its side. An iron piece 17 can be inserted into the slot 16. A rectangular hole is provided on the top of the base 6 leading to the slot 16, and the rectangular hole is aligned with the rectangular hole at the bottom of the insert block 5. Because the attraction force of the magnet 8 on the iron piece 17 in the slot 16 is greater than the sum of the elastic force of the two spring plates 12 and the total weight of the slider 7 and the magnet 8, when the iron piece 17 is inserted into the slot 16, the magnet 8 can move the slider 7 downward by attracting the iron piece 17. When the iron piece 17 is pulled out of the slot 16, the attraction force of the magnet 8 on the iron piece 17 disappears, and the slider 7 returns to its original position under the elastic force of the spring plates 12.

[0029] The bottom of the handrail body 1 and the top of the railing body 2 are provided with insertion holes 18 that can cooperate with the insertion block 5. The inner side wall of the insertion hole 18 is provided with two positioning holes 19 that can cooperate with the positioning block 10. Before installation, the positioning block 10 of the connector 3 is retracted into its insertion block 5. During installation, the insertion block 5 of the connector 3 is fully inserted into the insertion hole 18 of the handrail body 1 or the railing body 2. At this time, the positioning block 10 is aligned with the positioning hole 19. Then, the positioning block 10 is extended from the side of the insertion block 5 so that the positioning block 10 can be inserted into the positioning hole 19, thereby realizing a firm connection between the connector 3 and the handrail body 1 or the railing body 2.

[0030] The rotating component 4 includes two connecting blocks 20, which are respectively fixed on the base 6 of the two connecting components 3. Each of the two connecting blocks 20 has a through hole on its side, and a bolt 21 passes through both through holes. A nut 22 is connected to the bolt 21. By tightening the nut 22, the two connecting blocks 20 can be firmly fixed together. By loosening the nut 22, the two connecting components 3 can rotate, so that the handrail body 1 and the railing body 2 can rotate relative to each other to meet different usage needs.

[0031] Example 2: Based on Example 1, the traction method of the wire rope 15 is further optimized. A shaft 13 is installed in the middle of the rectangular hole of the insert block 5. Two guide wheels 14 are rotatably installed on the shaft 13. Both guide wheels 14 have circumferential deep grooves. The two wire ropes 15 pass around the two guide wheels 14 respectively, and the wire ropes 15 are located in the deep grooves of the guide wheels 14. The function of the deep grooves is to prevent the wire ropes 15 from detaching from the guide wheels 14. Through the guiding action of the guide wheels 14, it can be ensured that the wire ropes 15 can smoothly drive the side slider 9 to slide, avoiding the phenomenon of the wire ropes 15 getting stuck during the transmission process.

[0032] Usage procedure: Before connection, insert the iron plate 17 into the slot 16. The lower slider 7 slides down under the attraction of the magnet 8 on the iron plate 17. The two side sliders 9 slide inward simultaneously under the traction of the steel wire rope 15. The two positioning blocks 10 retract into the insert block 5. Insert the insert block 5 into the insertion hole 18 of the handrail body 1. Then pull out the iron plate 17 inserted into the slot 16. The attraction of the magnet 8 on the iron plate 17 disappears. The two side sliders 9 slide outward simultaneously under the elastic force of the spring plate 12. The two positioning blocks 10 extend and insert into the two positioning holes 19 of the handrail body 1, completing the connection between the connector 3 and the handrail body 1. Then, perform the same operation to connect the other connector 3 to the railing 2, thus completing the connection between the handrail body 1 and the railing body 2.

[0033] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
