[0001] This utility model relates to the field of handrail guide technology, specifically the rotating handrail guide of escalators. Background Technology

[0002] Escalators, also known as moving walkways, are a type of transportation that uses a conveyor belt to move people. Escalators are generally inclined; pedestrians stand on the automatically moving steps at one end and are automatically carried to the other end, with the steps remaining horizontal throughout the journey. Compared to elevators, escalators occupy more space and their vertical movement is relatively slow. However, because escalators move continuously, unlike elevators where passengers have to wait for the car to arrive, their total passenger capacity is much higher. Therefore, they are commonly seen in high-traffic areas such as shopping malls and subways.

[0003] In the existing technology, the handrail support of the rotating handrail guide rail of the escalator is not a uniform arc shape, and the handrail belt is directly installed on the handrail support, which is inconvenient for subsequent disassembly and maintenance. Moreover, the connection strength will be reduced after disassembly and assembly. Therefore, a new technical solution needs to be designed to solve this problem. Utility Model Content

[0026] 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.

[0027] Please see Figure 1-4 This utility model provides a technical solution:

[0028] In this technical solution, the rotating handrail guide rail of the escalator includes an elevator guide block 3, a rotating bracket 2, and a handrail bracket 1. The elevator guide block 3 and the handrail bracket 1 are arranged parallel vertically. Both ends of the rotating bracket 2 are equipped with mating blocks 6, with the upper mating block 6 inserted into a slot at the end of the handrail bracket 1. The front side wall of the elevator guide block 3 has a drive groove 7, and the lower mating block 6 is inserted into the drive groove 7. The top of the mating block 6 has a fixing through hole 5, and fasteners are fitted inside the drive groove 7 within the fixing through hole 5. 9. Fastener 9 is installed in the fixed through hole 5; fastener 9 includes fastening screw 14 and anti-loosening screw 10, fastening screw 14 is screwed with fastening nut 11; anti-loosening groove 12 is opened at the bottom end of fastening screw 14, and anti-loosening screw 10 is screwed in anti-loosening groove 12; anti-loosening sleeve 13 is sleeved on the outside of anti-loosening screw 10, and three limiting posts 22 are installed on the outer wall of anti-loosening sleeve 13, the three limiting posts 22 are distributed in a triangle; the inner wall of each limiting post 22 is provided with a spiral groove 21 that cooperates with fastening screw 14.

[0029] In this technical solution, the elevator guide block 3 is a conventional arrangement for mounting a rotating handrail guide rail. Both the upper and lower ends of the rotating bracket 2 are integrally formed with mating blocks 6. The end of the handrail bracket 1 has a slot. The mating block 6 on the upper side of the rotating bracket 2 is inserted into the slot, and the mating block 6 on the lower side is inserted into the drive groove 7 on the side wall of the elevator guide block 3. The fixing through hole 5 on the mating block 6 corresponds to the fastener 9. The fastening screw 14 in the fastener is inserted into the fixing through hole 5 and secured by the anti-loosening screw 10 and... The anti-detachment sleeve is fixed, the fastener 9 is installed, and the fastening screw 14 and the fastening nut 11 cooperate to realize the bolt in the prior art. An anti-detachment screw groove 12 is provided at the bottom end of the fastening screw 14, and the anti-detachment screw 10 is screwed in. Three limiting posts 22 installed on the anti-detachment sleeve 13 outside the anti-detachment screw 10 hold the fastening nut 11, thereby limiting the fastening nut 11 in the circumference. The spiral groove 21 on the limiting post 22 engages with the fastening screw 14, thereby limiting the anti-detachment sleeve 13 and the anti-detachment screw 10.

[0030] In some technical solutions, the inner wall of the anti-detachment cylinder 13 is provided with a reverse internal thread, and the outer part of the anti-detachment screw 10 that fits with the anti-detachment cylinder 13 is provided with a reverse external thread, and the reverse internal thread and the reverse external thread are matched.

[0031] In this technical solution, the external thread of the anti-detachment screw 10 is divided into two parts. The front part mates with the internal thread of the anti-detachment screw groove 12, and the rear part mates with the reverse internal thread of the anti-detachment cylinder 13, thereby installing the anti-detachment cylinder 13 on the outside of the anti-detachment screw 10.

[0032] In some technical solutions, the outer wall of the fastening nut 11 is provided with an annular groove 20, and the end of the limiting post 22 is set in the annular groove 20.

[0033] In this technical solution, when the anti-loosening screw 10 is screwed into the anti-loosening screw groove 12, the anti-loosening cylinder 13 will rotate accordingly. When the limiting post 22 contacts the fastening nut 11, it can rotate in the annular rotating groove 20 until it contacts the inner wall of the annular rotating groove 20, thereby holding the fastening nut 11 in place and performing axial limiting.

[0034] In some technical solutions, a retaining ring 19 is fixedly installed on the upper outer end of the fastening screw 14, and an annular pressure plate 17, a spring 15 and an annular rubber sheet 16 are fitted on the circumferential surface of the fastening screw 14. An extrusion block 18 is fixedly installed at the lower edge of the annular pressure plate 17.

[0035] In this technical solution, when the fastening screw 14 is rotated, the annular rubber sheet 16 slides upward due to the action of the screw hole. With further tightening, the annular rubber sheet 16 contacts the fixing ring 19. The annular rubber sheet 16 deforms due to the action of the fixing ring 19, sealing the screw hole. The spring 15 is located on the upper side of the annular pressure plate 17, causing the annular pressure plate 17 to be pressed downward due to the action of the spring 15. The compression block 18 is pressed downward due to the action of the annular pressure plate 17, causing the compression block 18 to further compress the edge of the annular rubber sheet 16, thereby improving the sealing effect. The annular pressure plate 17 is located on the upper side of the fixing ring 19, the spring 15 is located on the upper side of the annular pressure plate 17, and the annular rubber sheet 16 is located on the lower side of the fixing ring 19. The compression block 18 is fixedly installed at the lower edge of the annular pressure plate 17.

[0036] In some technical solutions, the outer wall of the rotary support 2 is equipped with a rolling bearing assembly 4.

[0037] In some technical solutions, the top of the elevator guide block 3 is equipped with an equipment mounting plate 8.

[0038] In this technical solution, it is used for the installation of elevator guide block 3.
