[0004] Regarding the aforementioned technologies, the inventors have discovered the following defects in this patent:

[0005] When the caster track is on the stair rail for a long time, dust and debris can easily enter the caster track, causing the caster to stop rolling and thus delaying escape time.

[0006] Therefore, in response to the above problems, the applicant provides a handrail track for emergency escape in high-rise buildings. Utility Model Content

[0007] In order to solve the problems mentioned in the background art, this application provides a handrail track for emergency escape in high-rise buildings.

[0008] This application provides a handrail track for emergency escape in high-rise buildings, which adopts the following technical solution:

[0009] A high-rise building emergency escape handrail track includes a track and casters. The track is equipped with a partition mechanism, which includes a fixed shaft, a torsion spring, and a dust cover. The bottom of the dust cover is engaged with the torsion spring, and the bottom surface of the dust cover is rotatably connected to the fixed shaft.

[0010] The omnidirectional wheel is equipped with a braking mechanism, which includes a brake caliper, a brake cable, and a brake brake. The brake caliper and the brake brake are connected by a brake cable.

[0011] Optionally, the track is fixedly connected to the top surface of the stair handrail, and two rows of multiple equidistant fixed shafts are fixedly connected to the top of the track. Both the track and the dust cover are provided with slots, and the top and bottom of the torsion springs are respectively engaged in the slots of the track and the dust cover.

[0012] Optionally, pulley grooves are provided on both sides of the track, and universal wheel grooves are provided on the top of the track. Two rows of multiple dust-proof plates are covered on the universal wheel grooves.

[0013] Optionally, four pulleys are rolledly connected to the two pulley grooves, and the central rings of the four pulleys are rotatably connected to corresponding fixed shafts. The four shafts are rotatably connected to fixed columns, and the tops of the four fixed columns are jointly fixedly connected to a top plate.

[0014] Optionally, a brake caliper is installed at the bottom of the top plate, and a caster wheel is installed on the brake caliper.

[0015] Optionally, a connecting column is fixedly connected to one side of the top plate, a handrail is installed on the connecting column, and a brake is installed at one corner end of the handrail.

[0016] Optionally, the top plate is fixedly connected to a support column, and one end of the support column is fixedly connected to a standing plate.

[0017] Optionally, a partition plate is fixedly connected between two adjacent fixed columns, and the partition plate is located in the universal wheel groove.

[0018] In summary, this application includes the following beneficial technical effects:

[0019] 1. This utility model, through the setting of the separation mechanism, separates the two rows of dust-proof plates by the casters and the separation plate, allowing the casters to roll in the caster groove. After the casters pass the dust-proof plate, the torsion spring is limited between the dust-proof plate and the track. The rebound force of the torsion spring will cause the dust-proof plate to cover the caster groove again, thereby effectively preventing the entry of dust and debris. This avoids the casters from stopping due to obstacles, and also avoids the casters from being bumped by obstacles, making the casters run more smoothly and giving escapees the best escape time.

[0020] 2. Through the setting of the braking mechanism, when the omnidirectional wheel slides too fast, the escapee can squeeze the brake to make the brake be transmitted through the brake cable to the brake caliper to lock the omnidirectional wheel or slow down the speed of the wheel sliding down. When the omnidirectional wheel slides down too fast and causes obstacles and crowds to gather in front, it can quickly decelerate or brake completely to avoid the risk of collision.

[0028] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0029] This application discloses a handrail track for emergency escape in high-rise buildings.

[0030] like Figure 1-6 As shown, a high-rise building emergency escape handrail track includes a track 1 and casters 10. The track 1 is equipped with a partition mechanism, which includes a fixed shaft 2, a torsion spring 3 and a dust cover 4. The bottom of the dust cover 4 is engaged with the torsion spring 3, and the bottom surface of the dust cover 4 is rotatably connected to the fixed shaft 2.

[0031] The caster wheel 10 is equipped with a braking mechanism, which includes a brake caliper 11, a brake cable, and a brake brake 15. A brake cable connects the brake caliper 11 and the brake brake 15.

[0032] Please see Figure 1The track 1 is fixedly connected to the top surface of the stair handrail. The top of the track 1 is fixedly connected to two rows of multiple equidistant fixed shafts 2. Both the track 1 and the dust cover 4 are provided with slots. The slots of the track 1 and the dust cover 4 are respectively engaged with the top and bottom of the torsion spring 3. A torsion spring 3 is set between fifty adjacent fixed shafts 2. The dust cover 4 rotates around the center of the fixed shaft 2, which can drive the torsion spring 3 to generate elastic force and rotate to a certain angle. When the dust cover 4 is not subjected to external force, the rebound force of the torsion spring 3 drives the dust cover 4 to return to its original position.

[0033] Please see Figure 1 Both sides of the track 1 are provided with pulley grooves 100, and the top of the track 1 is provided with a universal wheel groove 101. The universal wheel groove 101 is covered with two rows of multiple dustproof plates 4. The dustproof plates 4 are placed on the universal wheel groove 101 mainly to prevent dust, debris and human-inserted obstacles from entering the universal wheel groove 101.

[0034] Please see Figure 1 Four pulleys 9 are rolled on the two pulley grooves 100. The central rings of the four pulleys 9 are rotatably connected to the corresponding fixed shafts 8. The four shafts 8 are rotatably connected to the fixed columns 7. The top of the four fixed columns 7 are fixedly connected to the top plate 6. The cooperation between the four pulleys 9 and the pulley grooves 100 is used to limit the position of the top plate 6 to prevent it from tilting. It is also set to allow the top plate 6 to move down in the pulley grooves 100 through the pulleys 9.

[0035] Please see Figure 5 A brake caliper 11 is installed at the bottom of the top plate 6, and a caster wheel 10 is installed on the brake caliper 11. The caster wheel 10 is mainly set up to facilitate its coordination with the curvature and turning of the stair handrail. The brake caliper 11 and the brake 15 are mainly based on the braking principle of bicycles in the prior art. The braking principle of bicycles is prior art, and its specific structure and operating principle will not be elaborated here. At the same time, the brake line is not drawn in this application document. The brake line is mentioned here mainly to facilitate the user to stop the caster wheel 10 by using the brake caliper 11 to contact both sides of the wheel hub of the caster wheel 10 when the user grips the brake 15.

[0036] Please see Figure 5 A connecting column 13 is fixedly connected to one side of the top plate 6. A handrail 14 is installed on the connecting column 13. A brake 15 is installed at one corner end of the handrail 14. The main function of the handrail 14 is to make it easier for escapees to hold onto the handrail 14 and avoid leaning forward.

[0037] Please see Figure 1 The top plate 6 is fixedly connected to a support column 16, and one end of the support column 16 is fixedly connected to a standing plate 17. The standing plate 17 is designed to facilitate the user's standing.

[0038] Please see Figure 1 A partition plate 12 is fixedly connected between two adjacent fixed columns 7. The partition plate 12 is located in the universal wheel groove 101. The universal wheel groove 101 is used to separate the two rows of dust cover plates 4 so that they can rotate, thereby facilitating the universal wheel 10 to roll in the universal wheel groove 101.

[0039] The implementation principle of a high-rise building emergency escape handrail track according to an embodiment of this application is as follows:

[0040] The survivor stands on the standing platform 17, holding onto the handrail 14 with one hand and gripping the brake 15 with the other. When the brake 15 is released, the brake caliper 11 disengages from the wheel of the caster 10. At this time, the pulley 9 rolls in the pulley groove 100, and the caster 10 rolls in the caster groove 101. Simultaneously, the partition plate 12 separates the two rows of dust shields 4 covering the caster groove 101, causing the dust shields 4 that were originally covering the caster groove 101 to move to both sides, as shown in the attached diagram of the instruction manual. Figure 6 The state shown;

[0041] When the caster wheel 10 passes the dust cover 4, the torsion spring 3 is positioned between the dust cover 4 and the track 1. The rebound force of the torsion spring 3 will cause the dust cover 4 to cover the caster wheel groove 101 again, thereby effectively preventing dust and debris from entering. This avoids obstacles from blocking the normal operation of the caster wheel 10, and also prevents the caster wheel 10 from being bumped by obstacles, thus making the caster wheel 10 run more smoothly.

[0042] When the omnidirectional wheel 10 slides too fast, the escapee can squeeze the brake 15 to make the brake 15 transmit the brake cable to the brake caliper 11 to lock the wheel of the omnidirectional wheel 10 or slow down the speed of the wheel sliding down. When the omnidirectional wheel 10 slides down too fast and causes obstacles and crowds to gather in front, it can quickly slow down or brake completely to avoid the risk of collision.

[0043] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
