Description

Technical Field

[0001] This utility model relates to the field of elevator component technology, specifically a handrail device for a sightseeing elevator. Background Technology

[0002] A sightseeing elevator is a vertical lift powered by an electric motor, equipped with a box-shaped cabin, used in multi-story buildings for transporting passengers or goods. One or more walls of the shaft and the car are made of transparent material, allowing passengers to view the scenery outside the car while riding the elevator.

[0003] An investigation revealed that a Chinese utility model patent discloses a sightseeing elevator car with handrails (publication number: CN209009936U), which includes a car body and a handrail body. The handrail body includes a vertical support rod and a horizontally arranged arc-shaped handrail. At least two support rods are provided, and the lower end of the support rod is threaded to the bottom wall of the car body. The arc-shaped handrail is provided with a socket hole, and the upper end of the support rod is sleeved in the socket hole.

[0004] Although the aforementioned patent allows for the detachable armrests through the use of various bolts, facilitating transportation and installation, this device employs a fixed double armrest structure. The upper and lower armrests are arranged vertically and parallel and are statically fixed. The lower armrest lacks a height adaptive adjustment mechanism, making it impossible to dynamically match the body size of a child user. Since the two armrests are level, when a child holds onto the lower armrest, it is easy for their forehead to interfere with and collide with the upper armrest when they lean forward, making it inconvenient to use.

[0005] Therefore, this utility model provides a handrail device for a sightseeing elevator to solve the above problems. Utility Model Content

[0006] (a) Technical problems to be solved

[0007] This utility model provides a handrail device for a sightseeing elevator, which aims to solve the problems mentioned in the background art.

[0008] (II) Technical Solution

[0009] To achieve the above objectives, this utility model provides the following technical solution: It includes an elevator body, on which an upper handrail is installed. Multiple support rods are fixedly connected between the upper handrail and the elevator body. A lower handrail is located below the upper handrail. All support rods slide through the lower handrail. Two auxiliary handrails are symmetrically connected to the lower handrail. A worm gear and a worm are connected between each of the two auxiliary handrails and the lower handrail. An adjustment mechanism is provided between the lower handrail and the elevator body. The adjustment mechanism includes two lead screws and two sliders, with the two lead screws threadedly connected to the two sliders respectively.

[0010] As a preferred technical solution of this application, the lower armrest is symmetrically provided with storage slots, and the two auxiliary armrests are respectively rotatably connected in the two storage slots. The top of the storage slot is provided with a connecting slot, and the worm gear and worm are rotatably connected in the connecting slot, with the worm gear meshing with the worm. The worm gear is coaxially fixed with the auxiliary armrest.

[0011] As a preferred technical solution of this application, baffles are symmetrically fixed on the elevator body, and mounting grooves are opened in the side wall of the elevator body. Both lead screws are rotatably connected to the mounting grooves, and both sliders are slidably connected to the mounting grooves. Both sliders are fixedly connected to the lower handrail.

[0012] As a preferred technical solution of this application, the adjustment mechanism further includes two pulleys, both of which are rotatably connected in the mounting groove, and the two pulleys are respectively fixed coaxially with the two lead screws, and a transmission belt is connected between the two pulleys.

[0013] As a preferred technical solution of this application, the bottom of the elevator body is fixedly connected to a mounting shell, and a motor is fixedly connected inside the mounting shell. The output end of the motor extends into the mounting groove and is fixed coaxially with the lead screw.

[0014] As a preferred technical solution of this application, a handle is rotatably connected to the side wall of the lower handrail, and the handle is fixed coaxially with the worm gear.

[0015] (III) Beneficial Effects

[0016] The position and height of the lower armrest can be adjusted by setting an adjustment mechanism. Starting the motor can drive the adjustment mechanism to operate. The lead screw in the adjustment mechanism drives the slider to rise and fall, thereby adjusting the position of the lower armrest. Then, the worm gear and worm wheel can be rotated to make the auxiliary armrest rotate out of the storage slot. The position of the rotated auxiliary armrest is offset from that of the upper armrest, which can prevent children from colliding with the upper armrest when holding the auxiliary armrest.

[0024] 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.

[0025] This utility model provides a handrail device for a sightseeing elevator, such as... Figures 1-5 As shown, the technical solution includes an elevator body 1, an upper handrail 3 installed on the elevator body 1, and multiple support rods 4 fixedly connected between the upper handrail 3 and the elevator body 1. A lower handrail 5 is provided below the upper handrail 3, and the multiple support rods 4 slide through the lower handrail 5. Two auxiliary handrails 8 are symmetrically connected to the lower handrail 5. A worm gear 13 and a worm 14 are connected between the two auxiliary handrails 8 and the lower handrail 5. The worm gear 14 and the worm 13 can be rotated to drive the auxiliary handrails 8 out of the storage slot 7. The position of the rotated auxiliary handrails 8 is offset from that of the upper handrail 3, which can prevent children from colliding with the upper handrail 3 when holding the auxiliary handrails 8. An adjustment mechanism is provided between the lower handrail 5 and the elevator body 1. The adjustment mechanism includes two lead screws 10 and two sliders 11. The two lead screws 10 are respectively threadedly connected to the two sliders 11. The position and height of the lower handrail 5 can be adjusted by setting the adjustment mechanism. Rotating the lead screws 10 in the adjustment mechanism can drive the sliders 11 to rise and fall, thereby driving the lower handrail 5 to rise and fall.

[0026] The lower handrail 5 has symmetrically provided storage slots 7, and two auxiliary handrails 8 are rotatably connected to the two storage slots 7 respectively. The top of the storage slot 7 has a connecting slot 12, and the worm gear 13 and worm 14 are rotatably connected to the connecting slot 12. The worm gear 13 meshes with the worm 14, and the worm gear 13 is coaxially fixed with the auxiliary handrail 8. A handle 15 is rotatably connected to the side wall of the lower handrail 5, and the handle 15 is coaxially fixed with the worm 14.

[0027] When in use, rotating the handle 15 drives the worm gear 14 to rotate, which in turn drives the meshing worm wheel 13 to rotate, thereby driving the auxiliary handrail 8 connected to the worm wheel 13 to rotate. This allows the auxiliary handrail 8 to be rotated out of the storage slot 7, making it convenient for children to hold on. It should be noted that there is a self-locking property between the worm wheel 13 and the worm gear 14. Rotating the worm gear 14 can drive the meshing worm wheel 13 to rotate, while rotating the worm wheel 13 cannot drive the meshing worm gear 14 to rotate. This allows the auxiliary handrail 8 to be positioned at any location, improving its stability and making it easier for children to hold on.

[0028] A baffle 6 is symmetrically fixed on the elevator body 1. An installation groove 9 is opened in the side wall of the elevator body 1. Two lead screws 10 are rotatably connected to the installation groove 9. Two sliders 11 are slidably connected in the installation groove 9. The two sliders 11 are fixedly connected to the lower handrail 5. The adjustment mechanism also includes two pulleys 16. The two pulleys 16 are rotatably connected in the installation groove 9. The two pulleys 16 are coaxially fixed to the two lead screws 10 respectively. A transmission belt 17 is connected between the two pulleys 16. An installation shell 2 is fixedly connected to the bottom of the elevator body 1. A motor 18 is fixedly connected in the installation shell 2. The output end of the motor 18 extends into the installation groove 9 and is coaxially fixed to the lead screw 10.

[0029] When in use, the start motor 18 drives the lead screw 10 and the coaxially fixed pulley 16 to rotate. The rotating pulley 16 drives another pulley 16 and the lead screw 10 to rotate through the transmission belt 17. The two synchronously rotating lead screws 10 drive the two sliders 11 to rise and fall synchronously, which in turn drives the lower armrest 5 fixed to the sliders 11 to rise and fall. This allows the height of the lower armrest 5 to be adjusted according to the height needs of the child. It should be noted that the motor 18 is connected to an external power source through wires. The external power source includes a battery for providing power to the motor 18 and a control switch for controlling its start and stop. The external power source is existing technology. The specific model and specifications of the motor 18 need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts existing technology in this field, so it will not be described in detail.

[0030] In summary: During operation, the starting motor 18 drives the lead screw 10 and the coaxially fixed pulley 16 to rotate. The rotating pulley 16 drives another pulley 16 and the lead screw 10 to rotate through the transmission belt 17. The two synchronously rotating lead screws 10 drive the two sliders 11 to rise and fall synchronously, which in turn drives the lower handrail 5 fixed to the slider 11 to rise and fall, thereby adjusting the height of the lower handrail 5.

[0031] Then, turning the handle 15 causes the worm gear 14 to rotate, which in turn causes the meshing worm wheel 13 to rotate, thereby causing the auxiliary handrail 8 connected to the worm wheel 13 to rotate, thus rotating the auxiliary handrail 8 out of the storage slot 7 for children to hold on to.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
