Description

Technical Field

[0001] The utility model relates to the technical field of home elevator landing doors, in particular to a home elevator landing door device. Background Art

[0002] The landing door device of a home elevator usually consists of door leaves, door frames, door tracks, door locks, door leaf movement systems, etc. The door leaves are usually made of metal or glass, the door frames are frame structures fixed to the walls of the elevator shaft, and the door tracks are used to support the door leaves and enable them to move when opening and closing. The door lock is used to ensure that the door can be firmly locked when closed to prevent accidental opening. The door leaf movement system includes motors, wheel sets, guide rails and other components to control the movement of the door leaves and realize the functions of opening and closing;

[0003] The landing door should be a door without holes, and the net height should not be less than 2m. After the landing door is closed, the gap between the door leaves and between the door leaves and the columns, lintels and sills should be as small as possible, 1-6mm for passenger elevators and 1-8mm for freight elevators. However, in actual use, the landing door structure itself has tolerances, and the tolerances will continue to increase after long-term operation. The distance between the elevator cargo compartment and the floor often fluctuates, and when people pass by, it is easy for items to fall into the shaft through the gap.

[0004] Based on the above content, a home elevator floor door device is now proposed. Utility Model Content

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0006] A home elevator floor door device comprises a closing mechanism, buffer mechanisms are fixedly installed on both sides of the closing mechanism, a driving mechanism is fixedly installed on one end of the buffer mechanism, a floor is arranged above the closing mechanism, an elevator cargo compartment is arranged on one side of the floor, the closing mechanism comprises a sealing plate; the buffer mechanism comprises a sleeve; and the driving mechanism comprises a motor.

[0007] A further improvement of the technical solution of the utility model is that sliding blocks are fixedly installed on the tops of both sides of the sealing plate, and a side plate is fixedly installed on one end of the sliding block.

[0008] A further improvement of the technical solution of the utility model is that the closing mechanism is fixedly connected to the buffer mechanism through a side plate.

[0009] A further improvement of the technical solution of the utility model is that the inner part of the sleeve is slidably engaged with a limit plate, one end of the limit plate is fixedly mounted with a slide rod, and the other end of the limit plate and located inside the sleeve is fixedly mounted with a spring.

[0010] A further improvement of the technical solution of the utility model is that the buffer mechanism is fixedly connected to the closing mechanism via a sliding rod.

[0011] A further improvement of the technical solution of the utility model is that the buffer mechanism is fixedly connected to the driving mechanism through a sleeve.

[0012] A further improvement of the technical solution of the utility model is that: a driving tooth is installed at one end of the motor, the driving tooth is engaged with a rack, and a slide rail is fixedly installed on the top of the rack.

[0013] A further improvement of the technical solution of the utility model is that the slide rail is slidably installed at the bottom of the floor.

[0014] Due to the adoption of the above technical solution, the utility model has achieved the following technical progress compared with the prior art:

[0015] 1. The utility model provides a floor door device for a household elevator. A sealing plate is installed at the bottom of a floor through a slider, and is flush with the floor without affecting the normal operation of the elevator cargo compartment. When the elevator cargo compartment stops at the floor, the closing mechanism is fixedly connected to the buffer mechanism through the side plate, and the driving mechanism pushes the sealing plate to move out along the floor through the buffer mechanism. There is a tolerance when the elevator cargo compartment is running. When the elevator cargo compartment stops and the bottom is higher than the sealing plate, the sealing plate is moved out and located below the interval between the elevator cargo compartment and the floor to block the interval to prevent items from falling from the interval into the shaft when people enter the elevator cargo compartment from the floor. When the bottom of the elevator cargo compartment stops and is flush with one end of the sealing plate, one side of the sealing plate moves out to hold up one side of the bottom of the elevator cargo compartment to block the interval between the floor and the elevator cargo compartment.

[0016] 2. The utility model provides a floor door device for a household elevator. The driving mechanism pushes the sealing plate to move out along the floor through the buffer mechanism. When the sealing plate is pressed against the elevator cargo compartment, the slide bar pushes the spring through the limit plate. Even if the elevator cargo compartment shakes when people get on and off, the sealing plate can always fit the bottom of the elevator cargo compartment. When the driving mechanism pushes the closing mechanism to contact the elevator cargo compartment, the spring buffering action will not generate a large extrusion force, thereby protecting the relevant structures.

[0017] 3. The utility model provides a floor door device for a household elevator, in which a slide rail is slidably connected to the bottom of the floor, a driving tooth engages with a rack, and a buffer mechanism is fixedly installed at one end of the slide rail. When the motor drives the driving tooth to rotate, the slide rail is driven to move at the bottom of the floor, thereby pushing the closing mechanism to move out to seal the interval between the elevator cargo compartment and the floor.

DETAILED DESCRIPTION

[0024] The present invention is further described in detail below in conjunction with the embodiments:

[0025] like Figure 1-2 As shown, the utility model provides a household elevator floor door device, including a closing mechanism 1, buffer mechanisms 3 are fixedly installed on both sides of the closing mechanism 1, a driving mechanism 4 is fixedly installed on one end of the buffer mechanism 3, a floor 2 is arranged above the closing mechanism 1, and an elevator cargo compartment 5 is arranged on one side of the floor 2.

[0026] like Figure 3 As shown, the utility model provides a technical solution: preferably, the closing mechanism 1 includes a closing plate 11, sliders 12 are fixedly installed on the top of both sides of the closing plate 11, a side plate 13 is fixedly installed on one end of the slider 12, and the closing mechanism 1 is fixedly connected to the buffer mechanism 3 through the side plate 13.

[0027] In this embodiment, the sealing plate 11 is installed at the bottom of the floor 2 through the slider 12, and is flush with the floor 2 without affecting the normal operation of the elevator cargo compartment 5. When the elevator cargo compartment 5 stops at the floor 2, the closing mechanism 1 is fixedly connected to the buffer mechanism 3 through the side plate 13, and the driving mechanism 4 pushes the sealing plate 11 to move out along the floor 2 through the buffer mechanism 3. There is a tolerance during the operation of the elevator cargo compartment 5. When the elevator cargo compartment 5 stops and the bottom is higher than the sealing plate 11, the sealing plate 11 moves out and is located below the gap between the elevator cargo compartment 5 and the floor 2 to block the gap to prevent people from entering the elevator cargo compartment 5 from the floor 2. When the items fall from the gap into the shaft, and when the bottom of the elevator cargo compartment 5 is flush with one end of the sealing plate 11 after the elevator cargo compartment 5 stops, one side of the sealing plate 11 moves out to support one side of the bottom of the elevator cargo compartment 5 to block the gap between the floor 2 and the elevator cargo compartment 5.

[0028] like Figure 4As shown, the utility model provides a technical solution: preferably, the buffer mechanism 3 includes a sleeve 32, the internal sliding clamping of the sleeve 32 is connected to the limiting plate 33, one end of the limiting plate 33 is fixedly installed with a sliding rod 31, and the other end of the limiting plate 33 and located inside the sleeve 32 is fixedly installed with a spring 34, the buffer mechanism 3 is fixedly connected to the closing mechanism 1 through the sliding rod 31, and the buffer mechanism 3 is fixedly connected to the driving mechanism 4 through the sleeve 32.

[0029] In this embodiment, the driving mechanism 4 pushes the closing plate 11 to move out along the floor 2 through the buffer mechanism 3. When the closing plate 11 is pressed against the elevator cargo compartment 5, the slide rod 31 pushes the spring 34 through the limit plate 33. Even if the elevator cargo compartment 5 shakes when people get on and off, the closing plate 11 can always fit the bottom of the elevator cargo compartment 5. When the driving mechanism 4 pushes the closing mechanism 1 to contact the elevator cargo compartment 5, the spring 34 will not generate a large extrusion force under the buffering action, thereby protecting the relevant structures.

[0030] like Figure 5 As shown, the utility model provides a technical solution: preferably, the driving mechanism 4 includes a motor 44, one end of the motor 44 is driven and installed with a driving tooth 43, the driving tooth 43 is meshed with a rack 41, the top of the rack 41 is fixedly installed with a slide rail 42, and the slide rail 42 is slidably installed at the bottom of the floor 2.

[0031] In this embodiment, the slide rail 42 is slidably engaged at the bottom of floor 2, the driving tooth 43 engages with the rack 41, and the buffer mechanism 3 is fixedly installed at one end of the slide rail 42. When the motor 44 drives the driving tooth 43 to rotate, the slide rail 42 is driven to move at the bottom of floor 2, thereby pushing the closing mechanism 1 to move out to block the gap between the elevator cargo compartment 5 and floor 2.

[0032] The working principle of the home elevator floor door device is specifically described below.

[0033] like Figure 1-5As shown, the sealing plate 11 is installed at the bottom of the floor 2 through the slider 12, and is flush with the floor 2 without affecting the normal operation of the elevator cargo compartment 5. When the elevator cargo compartment 5 stops at the floor 2, the closing mechanism 1 is fixedly connected with the buffer mechanism 3 through the side plate 13, and the driving mechanism 4 pushes the sealing plate 11 to move out along the floor 2 through the buffer mechanism 3. There is a tolerance in the operation of the elevator cargo compartment 5. When the elevator cargo compartment 5 stops and the bottom is higher than the sealing plate 11, the sealing plate 11 moves out and is located below the gap between the elevator cargo compartment 5 and the floor 2 to block the gap to prevent people from entering the elevator cargo compartment 5 from the floor 2. When the goods fall into the shaft from the gap, and when the bottom of the elevator cargo compartment 5 is flush with one end of the sealing plate 11 after the elevator cargo compartment 5 stops, one side of the sealing plate 11 moves out to support one side of the bottom of the elevator cargo compartment 5, thereby blocking the gap between the floor 2 and the elevator cargo compartment 5. The gap is blocked, the driving mechanism 4 pushes the sealing plate 11 to move out along the floor 2 through the buffer mechanism 3. When the sealing plate 11 is pressed against the elevator cargo compartment 5, the slide bar 31 pushes the spring 34 through the limit plate 33. Even if the elevator cargo compartment 5 shakes when people get on and off, the sealing plate 11 can always fit the bottom of the elevator cargo compartment 5, and when the driving mechanism 4 pushes the closing mechanism 1 to contact the elevator cargo compartment 5, the spring 34 will not generate a large extrusion force under the buffering action, thereby protecting the relevant structures, the slide rail 42 slides and is connected to the bottom of the floor 2, the driving tooth 43 engages the rack 41, and the buffer mechanism 3 is fixedly installed at one end of the slide rail 42, when the motor 44 drives the driving tooth 43 to rotate, it drives the slide rail 42 to move at the bottom of the floor 2, thereby pushing the closing mechanism 1 to move out to block the gap between the elevator cargo compartment 5 and the floor 2.

[0034] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
