Downward-opening elevator ceiling structure

Abstract

This utility model relates to the field of elevator technology, specifically a downward-folding elevator ceiling structure. The fixed end of the side panel is hinged to the car top support, while the open end is detachably connected to the car top support. After the side panel is opened or closed, a locking component releases the movable end of the top panel. Simultaneously, when the top panel rotates open on the car top support, an elastic element connects the car top support and the movable end, allowing the top panel to open or close only at a certain angle before fully opening. This allows the top to be opened from inside the elevator car, facilitating subsequent maintenance of the car top or situations requiring top escape. This not only saves manpower and time but also reduces the workload of maintenance personnel. The two side panels and one top panel work together, simplifying the installation structure and allowing for a thinner design, thus providing more space within the elevator car.

Description

Technical Field

[0001] This utility model relates to the field of elevator technology, and specifically to a downward-folding elevator ceiling structure. Background Technology

[0002] Modern elevators mainly consist of a winch, guide rails, counterweight, safety devices (such as speed governors, safety brakes, and buffers), signal control system, car, and landing doors. The car is the body component that carries passengers or other loads. The car is a box-shaped space used by the elevator to carry and transport people and goods. The car is generally composed of major components such as the car floor, car walls, car top, and car doors, and its internal clear height should be at least 2m.

[0003] During elevator car use, the rotating plate or baffle is fixed to the top of the car using bolts. When components such as the light source inside the decorative ceiling need to be replaced, maintenance is usually done by unscrewing the bolts on the car top and supporting the decorative ceiling inside the car or by going to the outside of the car top. This makes it inconvenient for users to inspect and maintain the equipment on the top of the elevator car, and the disassembly time is long and the labor intensity is high. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a downward-opening elevator ceiling structure that can be opened from inside the car, reduces the labor intensity of maintenance personnel, and simplifies the installation structure.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] A downward-opening elevator ceiling structure includes:

[0007] The car has a roof support frame on its top;

[0008] A side assembly is disposed on the car roof support. The side assembly includes two side plates. The fixed end of the side plate is hinged to the car roof support, and the open end of the side plate is detachably connected to the car roof support.

[0009] A top surface assembly is disposed in the middle of the car roof support. The top surface assembly includes a top plate. A locking component is provided on the car roof support. The hinged end of the top plate is hinged to the car roof support, and the movable end of the top plate is connected to the locking component.

[0010] A connecting component is disposed between the top plate and the car roof support. The connecting component includes an elastic element, one end of which is connected to the car roof support, and the other end is detachably connected to the movable end of the top plate. The elastic element is used to allow the movable end of the top plate to open and close at a certain angle when the top plate is rotated open on the car roof support.

[0011] In one embodiment of this utility model, a fixing spring is provided on the open end of the side plate, and a limiting protrusion is provided on the fixing spring. A fixing seat is provided on the car top bracket, and two fixing rods are hinged on the fixing seat. A fixing spring is provided between the two fixing rods, so that a clamping structure for clamping the limiting protrusion is formed between the fixing ends on the two fixing rods.

[0012] In one embodiment of this utility model, a limiting rod is provided at one end of the fixing rod, and the two ends of the fixing spring are respectively passed through the limiting rods of the two fixing rods. A pressure ring is provided on the free end of the fixing rod; a fixing roller is rotated on the fixing end, and the fixing roller is arranged opposite to the limiting protrusion.

[0013] In one embodiment of this utility model, a hinge seat is provided on the bottom surface of the car roof bracket, and a side pivot is provided on the side plate. The side pivot is rotatably mounted on the hinge seat, so that the surface height of the side plate is lower than the surface height of the top plate.

[0014] In one embodiment of the present invention, a horizontal surface and a vertical surface are provided on the open end of the side plate, the horizontal surface and the vertical surface form a groove structure that matches the side edge of the top plate, a first gap is provided between the horizontal surface and the surface of the top plate, and a second gap is provided between the vertical surface and the side edge of the top plate.

[0015] In one embodiment of this utility model, the length of the horizontal surface is greater than the width of the second gap, so that the groove structure formed by the horizontal and vertical surfaces covers the side of the top plate.

[0016] In one embodiment of the present invention, the locking component includes a locking seat, a rotating shaft is rotatably mounted on the locking seat, a locking piece is mounted on the rotating shaft, a locking slot matching the locking piece is provided on the movable end of the top plate, and handles are vertically mounted at both ends of the rotating shaft. The locking piece on the rotating shaft is driven to pass through or move away from the locking slot by rotating the rotating shaft through the handles.

[0017] In one embodiment of this utility model, the elastic element includes a mounting block and an elastic rope. The mounting block is disposed on the car roof bracket, one end of the elastic rope is connected to the mounting block, the free end of the elastic rope is connected to a plastic clip, and a mounting hole is provided on the top plate, and the plastic clip is inserted into the mounting hole.

[0018] In one embodiment of this utility model, the elastic rope can be any one of a spring, elastic cord, rod, or rope.

[0020] The beneficial effects of this utility model are:

[0021] The fixed end of the side plate of this utility model is hinged to the car top bracket, and the open end is detachably connected to the car top bracket. After the side plate is opened and closed, the locking component releases the movable end of the top plate. At the same time, when the top plate is rotated open on the car top bracket, the elastic element connects the car top bracket and the movable end so that the top plate only opens and closes at a certain angle. Then the top plate is fully opened, and the top can be opened from inside the car. This facilitates subsequent maintenance of the car top and escape from the top. It not only saves manpower and time, but also reduces the labor intensity of maintenance personnel. The two side plates and one top plate are used together to simplify the installation structure, so they can be designed to be thinner, leaving more space for the elevator car.

[0028] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0029] Reference Figure 1-5 As shown, a downward-opening elevator ceiling structure includes:

[0030] The car 1 has a car roof support 11 installed on its top;

[0031] Side assembly 5 is disposed on the car roof support 11. The side assembly 5 includes two side plates 51. The fixed end 64 of the side plate 51 is hinged to the car roof support 11, and the open end of the side plate 51 is detachably connected to the car roof support 11.

[0032] A top surface assembly is disposed in the middle of the car roof support 11. The top surface assembly includes a top plate 2. A locking component 4 is disposed on the car roof support 11. The hinge end 21 of the top plate 2 is hinged to the car roof support 11, and the movable end 22 of the top plate 2 is connected to the locking component 4.

[0033] A connecting component 3 is disposed between the top plate 2 and the car roof support 11. The connecting component 3 includes an elastic element. One end of the elastic element is connected to the car roof support 11, and the other end is detachably connected to the movable end 22 of the top plate 2. The elastic element is used to allow the movable end 22 to open and close at a certain angle when the top plate 2 is rotated open on the car roof support 11.

[0034] The fixed end 64 of the side plate 51 of this utility model is hinged to the car top bracket 11, and the open end is detachably connected to the car top bracket 11. After the side plate 51 is opened and closed, the locking component 4 releases the movable end 22 of the top plate 2. At the same time, when the top plate 2 is rotated open on the car top bracket 11, the elastic element connects the car top bracket 11 and the movable end 22 so that the top plate 2 is only opened and closed at a certain angle. Then the top plate 2 is fully opened, and the top can be opened inside the car 1. This facilitates subsequent maintenance of the top of the car 1 and escape from the top. It not only saves manpower and time, but also reduces the labor intensity of maintenance personnel. The two side plates 51 and the top plate 2 are used together to simplify the installation structure, so it can be designed to be thinner, leaving more space for the elevator car 1.

[0035] In one embodiment of this utility model, a fixing spring 61 is provided on the open end of the side plate 51, and a limiting protrusion 69 is provided on the fixing spring 61. A fixing seat 68 is provided on the car top bracket 11, and two fixing rods 62 are hinged on the fixing seat 68. A fixing spring 63 is provided between the two fixing rods 62, so that a clamping structure 6 for clamping the limiting protrusion 69 is formed between the fixing ends 64 on the two fixing rods 62.

[0036] Specifically, the clamping structure 6 formed between the fixed ends 64 on the two fixed rods 62 clamps the limiting protrusion 69, forming a movable buckle structure, which can easily open and lock the side plate 51, making it convenient to use and stable in connection.

[0037] In one embodiment of the present invention, a limiting rod 65 is provided at one end of the fixing rod 62, and the two ends of the fixing spring 63 are respectively passed through the limiting rods 65 of the two fixing rods 62. A pressing ring 66 is provided on the free end of the fixing rod 62; a fixing roller 67 is rotatably provided on the fixing end 64, and the fixing roller 67 is arranged opposite to the limiting protrusion 69.

[0038] Specifically, the two ends of the fixing spring 63 are respectively inserted into the limiting rods 65 of the two fixing rods 62. Under the action of the fixing spring 63, the fixing end 64 on the fixing rod 62 keeps the limiting protrusion 69 clamped, ensuring the stability of the lock. The free end of the fixing rod 62 is provided with a pressure ring 66, which makes it convenient for personnel to open the side plate 51 from the top of the car 1, improving the ease of use. The fixing roller 67 is arranged opposite to the limiting protrusion 69, ensuring the clamping force on the limiting protrusion 69 while ensuring the smooth engagement of the lock.

[0039] In one embodiment of the present invention, a hinge seat 53 is provided on the bottom surface of the car roof support 11, and a side pivot 52 is provided on the side plate 51. The side pivot 52 is rotatably mounted on the hinge seat 53, so that the surface height of the side plate 51 is lower than the surface height of the top plate 2.

[0040] Specifically, the side pivot 52 is mounted on the hinge seat 53, so that the surface height of the side plate 51 is lower than the surface height of the top plate 2. This can cover the hinge seat 53, handle 44 and other components on the car top bracket 11, improving the cleanliness of the car 1. At the same time, the surface height of the side plate 51 is lower than the surface height of the top plate 2, which means that the side surface is closer to the ground of the car 1. The height difference between the side plate 51 and the top plate 2 makes it easier to open the side plate 51.

[0041] In one embodiment of the present invention, a horizontal surface 54 and a vertical surface 55 are provided on the open end of the side plate 51. The horizontal surface 54 and the vertical surface 55 form a groove structure that matches the side of the top plate 2. A first gap 56 is provided between the horizontal surface 54 and the surface of the top plate 2, and a second gap 57 is provided between the vertical surface 55 and the side of the top plate 2.

[0042] Specifically, the horizontal surface 54 and the vertical surface 55 form a groove structure that matches the side of the top plate 2. This not only facilitates the shielding of the side of the top plate 2, but also provides support when the top plate 2 falls off, ensuring safety. At the same time, a first gap 56 is provided between the horizontal surface 54 and the surface of the top plate 2, and a second gap 57 is provided between the vertical surface 55 and the side of the top plate 2. The gaps allow air to circulate, and the groove structure facilitates the opening of the side.

[0043] In one embodiment of the present invention, the length of the horizontal surface 54 is greater than the width of the second gap 57, so that the groove structure formed by the horizontal surface 54 and the vertical surface 55 covers the side of the top plate 2.

[0044] Specifically, the groove structure formed by the horizontal surface 54 and the vertical surface 55 covers the side of the top plate 2, which allows the side plate 51 to cover the side of the top plate 2, making it more aesthetically pleasing. At the same time, it can be easily inserted into the first gap 56 between the horizontal surface 54 and the surface of the top plate 2 by hand or with tools, ensuring the top is aesthetically pleasing while making it easier to open the side.

[0045] In one embodiment of this utility model, the locking component 4 includes a locking seat 41, a rotating shaft 42 is rotatably mounted on the locking seat 41, a locking piece 43 is mounted on the rotating shaft 42, a locking slot matching the locking piece 43 is provided on the movable end 22 of the top plate 2, and handles 44 are vertically mounted at both ends of the rotating shaft 42. The handles 44 drive the rotating shaft 42 to rotate, thereby causing the locking piece 43 on it to pass through or move away from the locking slot.

[0046] Specifically, the handle 44 on the car roof support 11 is exposed. The handle 44 drives the rotating shaft 42 to rotate, which in turn drives the locking piece 43 on it away from the locking slot. Without the restriction of the locking piece 43, the hinge end 21 of the top plate 2 rotates on the car roof support 11, and its movable end 22 falls down to open. It is practical, convenient and has a reasonable structural design.

[0047] In one embodiment of the present invention, the elastic element includes a mounting block 31 and an elastic rope 32. The mounting block 31 is disposed on the car roof support 11. One end of the elastic rope 32 is connected to the mounting block 31, and the free end of the elastic rope 32 is connected to a plastic clip 33. An installation hole is provided on the top plate 2, and the plastic clip 33 is inserted into the installation hole.

[0048] This application is not limited to the plastic clip 33 and the mounting hole structure; quick-release structures such as hooks can also be used.

[0049] Specifically, the connecting component 3 is located between the top plate 2 and the car top support 11. One end of the elastic rope 32 is connected to the mounting block 31, and the free end of the elastic rope 32 is connected to the plastic clip 33. The plastic clip 33 is inserted into the mounting hole, allowing the movable end 22 of the top plate 2 to open and close at a certain angle. This prevents the movable end 22 of the top plate 2 from suddenly falling down as a whole, causing the top plate 2 to fall off and injure people or objects, thus ensuring safety. Since the free end of the elastic rope 32 is connected to the plastic clip 33, and the plastic clip 33 is inserted into the mounting hole, after the movable end 22 of the top plate 2 opens and closes at a certain angle, the plastic clip 33 can be separated from the mounting hole to fully open the top plate 2, facilitating subsequent maintenance of the top of the car 1 and situations requiring top escape.

[0050] In one embodiment of this utility model, the elastic rope 32 can be any one of a spring, elastic rope, rod, or rope, or any combination of spring, elastic rope, rod, or rope. Its purpose is to pull and limit the movable end 22 of the top plate 2 to prevent it from falling off quickly. The elastic spring or elastic rope can provide a certain buffer force and will not cause a large pulling force on the top plate 2, thus ensuring the service life of the top plate 2.

[0051] In one embodiment of the present invention, a fixed opening is provided on the top plate 2, a light-diffusing plate 24 is provided on the fixed opening, and light sources of the top plate 2 are provided on both sides of the light-diffusing plate 24; a side opening is provided on the side plate 51, and a side light source is provided on the side opening.

[0052] Specifically, the top plate 2 light source is provided on both sides of the light-diffusing plate 24 to provide illumination. Since the space of the top plate 2 is small, this solution can greatly reduce the size of the lighting equipment and make it easy to use. The top plate 2 light source provided on both sides of the light-diffusing plate 24 can also provide continuous illumination after the top plate 2 is opened, improving the ease of use. Side light source is provided on the side opening to provide auxiliary lighting and ensure the lighting needs of the car 1.

[0053] Usage process

[0054] When maintenance of the top of the car 1 is required, or when top escape is needed, first open the side panels 51 on both sides of the top of the car 1. Use tools or your hands to insert them into the first gap 56 between the horizontal surface 54 and the surface of the top plate 2. Pull down the open end of the side panel 51. The clamping structure 6 formed by the fixed ends 64 on the two fixed rods 62 and the limiting protrusion 69 will loosen and move away, allowing the side panel 51 to rotate along the hinge seat 53, exposing the car top support 11 that was previously hidden by the side. At the same time, the handle 44 on the car top support 11 will also be exposed. The handle 44 drives the rotating shaft 42 to rotate, causing the locking piece 43 on it to move away from the locking slot. Without the restriction of the locking piece 43, the hinge end 21 of the top plate 2 rotates on the car top support 11, and its movable end 22 moves down. The top plate 2 is opened by connecting component 3 between the top plate 2 and the car top support 11. One end of the elastic rope 32 is connected to the mounting block 31, and the free end of the elastic rope 32 is connected to the plastic clip 33. The plastic clip 33 is inserted into the mounting hole, allowing the movable end 22 of the top plate 2 to open and close at a certain angle. This prevents the movable end 22 of the top plate 2 from suddenly falling down as a whole, causing the top plate 2 to fall off and injure people or objects, thus ensuring safety. Since the free end of the elastic rope 32 is connected to the plastic clip 33, and the plastic clip 33 is inserted into the mounting hole, after the movable end 22 of the top plate 2 opens and closes at a certain angle, the plastic clip 33 can be separated from the mounting hole to fully open the top plate 2. This facilitates subsequent maintenance of the top of the car 1 and escape from the top.

[0055] The above-described embodiments are merely preferred embodiments provided to fully illustrate the present invention, and the scope of protection of the present invention is not limited thereto. Equivalent substitutions or modifications made by those skilled in the art based on the present invention are all within the scope of protection of the present invention.
