[0003] In the prior art, a stair handrail with a protective structure, disclosed in application CN 117721969A, uses a reciprocating scraping and protective mechanism. When the scraping frame moves back and forth, the serrated edges cut the ice back and forth, enhancing both the scraping and cleaning effect and the protective effect. However, the following problems still exist: The aforementioned stair handrail uses a scraping frame to cut ice back and forth, cleaning and protecting the handrail. However, these handrails are all integrated, and when a part of the handrail is damaged, the entire handrail needs to be replaced, which is wasteful of resources. In addition, the handrails are fixed with bolts or welding, making installation difficult, time-consuming, and labor-intensive during maintenance and replacement.

[0016] (III) Beneficial Effects Compared with the prior art, the present invention provides a magnetic track modular stair handrail system, which has the following advantages: 1. This invention uses a connecting block that slides on the right side of the handrail body to slide the mounting block between two mounting plates. A metal spring plate controls the mounting plates to be fixedly connected to the mounting block.

[0018] 3. When the present invention is subjected to vibration, the support column pushes the damper downward, and the damping spring generates elastic potential energy, which, together with the damper, cancels out the energy generated by the vibration, thereby achieving the purpose of earthquake resistance and solving the earthquake resistance problem of the handrail.

[0019] 4. This invention uses a drive motor to control a lead screw block to move a cleaning rack along the outer wall of the handrail body, using a cleaning sponge to achieve the cleaning purpose.

Detailed Implementation

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Specific implementation examples are given below.

[0024] Please see Figures 1-9The present invention provides a magnetic track modular stair handrail system, including a stair body 1, an anti-seismic mechanism 2 located on both sides of the top of the stair body 1, and a handrail mechanism 3 located on the top of the anti-seismic mechanism 2. A connecting structure 4 is provided on the right side of the handrail mechanism 3, and a cleaning mechanism 5 is provided on the top of the handrail mechanism 3.

[0025] like Figure 1 , Figure 3 and Figure 6 As shown, the handrail mechanism 3 includes a support rail 301 and a handrail body 302. Guide grooves 303 are provided in the middle of both the front and rear sides of the support rail 301. First magnetic blocks 304 are fixedly connected to the inner walls of both guide grooves 303. Guide gears 305 are movably connected to the lower parts of both the front and rear sides of the support rail 301. Fixed grooves 306 are provided in the upper parts of both the front and rear sides of the support rail 301. Protrusions are fixedly connected to the middle of both the front and rear sides of the handrail body 302. Second magnetic blocks 307 are fixedly connected to the outer walls of the two protrusions. The handrail body 3... Guide grooves 308 are provided on the lower sides of the front and rear sides of the handrail body 302. Fixed screws 309 are threadedly connected to the upper sides of the front and rear sides of the handrail body 302. A first fixing block 3010 is movably connected to the opposite side of the two fixing screws 309. An LED light 3011 is fixedly connected to the opposite side of the two handrail bodies 302. The guide groove 303 is adapted to the protrusion. The first magnetic block 304 is magnetically connected to the second magnetic block 307. The guide gear 305 is meshed with the guide groove 308. The fixing groove 306 is adapted to the first fixing block 3010.

[0026] The above scheme involves connecting the protrusion to the guide groove 303. Under the meshing action of the guide gear 305 and the guide tooth groove 308, the support rail 301 is slidably connected to the handrail body 302. The handrail body 302 and the support rail 301 are quickly positioned and fixed by the magnetic fixation of the first magnetic block 304 and the second magnetic block 307. The fixing screw 309 is rotated, and under the action of the thread, the first fixing blocks 3010 on both sides are pushed to move towards each other, thereby completing the secondary fixation of the handrail body 302 and the support rail 301. The LED light 3011 provides lighting for the staircase body 1.

[0027] like Figure 1 , Figure 3 , Figure 4 and Figure 7As shown, a connecting base 3012 is fixedly connected to the right side of the handrail body 302. Metal spring plates 3013 are fixedly connected to both the front and rear sides of the inner wall of the connecting base 3012. Mounting clamps 3014 are fixedly connected to the opposite sides of the two metal spring plates 3013. The connecting structure 4 includes a connecting block 401. The connecting block 401 is located at the top right side of the handrail body 302. Placement slots 402 are opened on both the front and rear sides of the inner wall of the left end of the connecting block 401. Pull rods 403 are slidably connected to both the front and rear sides of the front part of the connecting block 401. Mounting blocks 404 are fixedly connected to the bottom of the two pull rods 403. A support spring 405 is sleeved on the outside of each pull rod 403. The mounting block 404 is elastically connected to the connecting block 401 through the support spring 405.

[0028] The above solution involves sliding the connecting block 401 to the right side of the handrail body 302, sliding the mounting block 404 between the two mounting plates 3014, and using the metal spring plate 3013 to push the mounting plates 3014 and the mounting block 404 into a fixed connection. To disassemble, pull the lever 403 to pull the mounting block 404 out between the two mounting plates 3014. Since the mounting block 404 is elastically connected to the connecting block 401 through the support spring 405, the mounting block 404 is pushed back to its original position under the elastic force of the support spring 405.

[0029] like Figure 1 and Figure 2 As shown, several supporting columns 201 are fixedly connected to the top of each step of the staircase body 1. A damper 202 is fixedly connected to the inner bottom of each supporting column 201. A damping spring 203 is sleeved on the outer wall of the top of each damper 202. A supporting column 204 is fixedly connected to the top of each damper 202. A limiting groove 205 is opened on the left side of the inner wall of each supporting column 201. A limiting slider 206 is set at the top of the limiting groove 205. The limiting slider 206 is fixedly connected to the supporting column 204. The top of the supporting column 204 is fixedly connected to the supporting rail 301.

[0030] The above solution works as follows: when subjected to vibration, the support column 204 pushes the damper 202 downward, compressing the damping spring 203 to generate elastic potential energy, which, together with the damper 202, cancels out the energy generated by the vibration, thus achieving the purpose of earthquake resistance.

[0031] like Figure 1 , Figure 5 , Figure 8 and Figure 9As shown, the cleaning mechanism 5 includes a support screw 501, which is movably connected to the inside of the top of the handrail mechanism 3. The front of the support screw 501 is fixedly connected to the output end of the drive motor 502. A screw sleeve block 503 is threadedly connected to the outer wall of the support screw 501. Connecting plates 504 are fixedly connected to both the front and rear sides of the screw sleeve block 503. Support blocks 507 are fixedly connected to the opposite sides of the two connecting plates 504. Fixing springs 508 are fixedly connected to the opposite sides of the two support blocks 507. Fixing springs 508 are fixedly connected to the opposite sides of the two fixing springs 508. A second fixing block 509 is attached, and the second fixing block 509 is elastically connected to the support block 507 via a fixing spring 508. Each of the two second fixing blocks 509 has a pressing block 5010 on its opposite side. Each of the two pressing blocks 5010 has a push rod 5011 fixedly connected to its opposite side. Each of the two push rods 5011 has a pressing plate 5012 fixedly connected to its opposite side. Each of the two support blocks 507 has a cleaning rack 505 on its opposite side. The cleaning rack 505 is slidably connected to the push rod 5011. Each of the cleaning racks 505 has a cleaning sponge 506 fixedly connected to its bottom.

[0032] Through the above scheme: the drive motor 502 starts and drives the support screw 501 to rotate. Under the action of the screw thread, the screw sleeve block 503 moves left and right. Under the action of the connecting plate 504, the cleaning frame 505 slides along the outer wall of the handrail body 302. The cleaning sponge 506 achieves the cleaning purpose. Pressing the pressing plate 5012, under the action of the push rod 5011, pushes the pressing block 5010 to squeeze the support block 507, so that the cleaning frame 505 can be separated and disassembled from the support block 507.

[0033] Working principle: In actual use, firstly, by connecting the protrusion with the guide groove 303, the first magnetic block 304 and the second magnetic block 307 are magnetically fixed to complete the quick positioning and fixing of the handrail body 302 and the support rail 301. By rotating the fixing screw 309, the first fixing blocks 3010 on both sides are pushed to move towards each other to complete the secondary fixing of the handrail body 302 and the support rail 301. The LED light 3011 is used to provide lighting for the stair body 1.

[0034] Secondly, by sliding the connecting block 401 on the right side of the handrail body 302, the mounting block 404 is slid between the two mounting plates 3014. The metal spring plate 3013 pushes the mounting plates 3014 to fix the mounting block 404. When disassembling, the mounting block 404 can be pulled out between the two mounting plates 3014 by pulling the pull rod 403. The support spring 405 pushes the mounting block 404 to reset.

[0035] Then, when subjected to vibration, the support column 204 pushes the damper 202 downward, generating elastic potential energy through the damping spring 203, which, together with the damper 202, cancels out the energy generated by the vibration, thus achieving the purpose of earthquake resistance.

[0036] Finally, the drive motor 502 drives the support screw 501 to rotate, pushing the screw sleeve block 503 to drive the cleaning frame 505 to slide along the outer wall of the handrail body 302. The cleaning sponge 506 is used to achieve the cleaning purpose. By pressing the pressing plate 5012, the pressing block 5010 is pushed to squeeze the support block 507, so that the cleaning frame 505 can be separated and disassembled from the support block 507.

[0037] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed invention.
