Description

Technical Field

[0001] The invention belongs to the technical field of anti-falling home elevators, and in particular relates to an anti-falling home elevator suitable for villas. Background Art

[0002] As people's living standards improve, more and more people move into home villas, and in order to facilitate going up and down stairs and carrying heavy objects between floors, they will choose to install elevators in their home villas. The design and appearance of home villa elevators are usually luxurious and high-end, focusing on coordination with the overall style of the villa. They use high-end materials such as stainless steel, glass and high-quality wood, and are equipped with exquisite decorative details and lighting effects to enhance the overall sense of luxury.

[0003] At the same time, in order to improve the safety of home elevators, home elevators adopt multiple protection measures to prevent falling and ensure the safety of the elevator during operation. Screw elevators are commonly used home elevators and are an anti-fall home elevator with excellent characteristics.

[0004] Although the existing anti-fall home elevators can ensure safety during use, there is a possibility that people will be trapped in the elevator and unable to escape after an abnormal shutdown. Due to the particularity of home elevators used in villas, after people are trapped in the elevator, the communication is interrupted, resulting in the people in the elevator being unable to contact the outside world, making it impossible for the trapped people in the elevator to be rescued in time; at the same time, in the event of a fire, the elevator does not have the ability to prevent fire, and there are great safety hazards when people are trapped. The information disclosed in this background technology section is only intended to enhance the understanding of the overall background of the invention and should not be regarded as an acknowledgment or any form of suggestion that the information constitutes the prior art already known to a person skilled in the art. Summary of the invention

[0005] The purpose of the present invention is to provide a fall-proof home elevator suitable for villas, which can solve the rescue problem when people are trapped in the elevator and cannot communicate with the outside world, and the rescue problem when people are trapped in the elevator when a fire occurs.

[0006] In order to achieve the above object, a technical solution provided by a specific embodiment of the present invention is as follows: An anti-fall home elevator suitable for villas, comprising: The elevator body includes an elevator car and an elevator shaft. The elevator car is installed in the elevator shaft. A glass door is installed at the entrance and exit of the elevator car. The glass door is used to close and open the entrance and exit of the elevator car. At the same time, the glass door has good sealing when closed on the elevator car, which can prevent external gas from entering through the gap between the glass door and the elevator car. A screw is fixedly connected in the elevator shaft, which is a guide and driving part when the elevator car runs in the elevator shaft.

[0007] The oxygen supply component includes a medium storage tank, which is arranged in the elevator car and near the top. The medium storage tank is provided with an oxygen generating medium. The oxygen generating medium will generate oxygen after being triggered, so as to provide oxygen to the people in the elevator in extreme situations such as fire, so as to buy time for the people to escape. A breathing component is installed on the side wall of the medium storage tank. The breathing component is provided with multiple oxygen generating mediums, and oxygen generated by the oxygen generating medium is provided to the passengers through the breathing component, so that the passengers can breathe the oxygen generated by the oxygen generating medium through the breathing component. At the same time, the breathing component is provided with multiple oxygen generating mediums, which can meet the use of normal family members, so that when there are more passengers in the elevator, there are enough breathing components for the people to use. When a fire occurs and causes people to be trapped in the elevator, when smoke enters the elevator car, it will pose a great threat to the safety of the people. In order to allow the people to breathe harmless oxygen, oxygen is generated by the oxygen generating medium, so that the people can breathe harmless oxygen through the breathing component, thereby ensuring that the people trapped in the elevator breathe normally during the fire, thereby buying time for the people to escape.

[0008] A manual drive assembly includes a driving gear, which is rotatably mounted on the bottom of an elevator car, a first driven gear is rotatably mounted on the bottom of the elevator car, the driving gear and the first driven gear are meshed and connected, a second driven gear is threadedly connected to the screw, the second driven gear and the first driven gear are meshed and connected, and a manual driving member is arranged on the driving gear, and the manual driving member is used to drive the driving gear to rotate. When the driving gear is driven to rotate by the manual driving member, the driving gear can drive the first driven gear to rotate, and the rotation of the first driven gear can drive the second driven gear to rotate. Since the second driven gear is threadedly connected to the screw, the elevator car can be moved up and down by the rotation of the second driven gear on the screw. In order to make the elevator stop after a malfunction occurs, when the communication is interrupted and the people in the elevator cannot contact the outside world, the passengers can take emergency measures, and drive the elevator car up and down by manually rotating the driving gear, so as to move the elevator car to the entrance and exit corresponding to the floor, so that the people can escape independently.

[0009] In one or more embodiments of the present invention, an insulating layer is provided on the outer wall of the elevator car, so that the temperature in the elevator car will not be affected by the high temperature outside when a fire occurs, ensuring the safety of passengers in the elevator car. The glass door includes a first glass layer and a second glass layer, and a flame retardant material is provided between the first glass layer and the second glass layer, and the flame retardant material includes one or more combinations of sodium aluminum silicate, calcium aluminum phosphate, nitrogen phosphorus flame retardant and foaming flame retardant. The first glass layer and the second glass layer are both made of insulating glass, so that the glass door has a good insulation effect. At the same time, in order to further ensure the insulation, a flame retardant material is provided in the gap between the first glass layer and the second glass layer. The flame retardant material can not only improve the insulation performance of the glass door, but also prevent the second glass layer provided on the inner side from being heated, so as to make the second glass layer safe, thereby protecting the personnel in the elevator car. At the same time, when the first glass layer on the outside reaches its limit of withstanding high temperature, the first glass layer melts and cracks, so that the flame retardant material can be released, and the fire is extinguished by the flame retardant material. Since the flame retardant material will expand after being heated, the expanded flame retardant material after the first glass layer cracks can be sprayed out. In order to prevent the first glass layer and the second glass layer from being affected by overpressure after the flame retardant material expands due to heat, the placement amount of the flame retardant material needs to be combined with the spatial setting of the gap between the first glass layer and the second glass layer.

[0010] In one or more embodiments of the present invention, a driving mechanism is installed on the rear side wall of the elevator car, and a rotating component is provided at the driving end of the driving mechanism and is threadedly connected to the screw rod, so that the elevator car can be driven to move up and down on the screw rod by the driving of the driving mechanism. A limit rod is fixedly connected in the elevator shaft, and a limit block is fixedly connected to the rear side wall of the elevator car. The limit block is slidably connected to the limit rod, and the cooperation between the limit rod and the limit block makes the elevator car stable when moving up and down. A mounting plate and a bottom plate are fixedly connected to the inner side wall of the elevator car, and the mounting plate is arranged at a position close to the top of the elevator car, and the bottom plate is arranged at a position close to the bottom. The mounting plate is used to install the top component, and the bottom plate is used to shield the bottom component.

[0011] In one or more embodiments of the present invention, the breathing assembly includes a delivery hose, an oxygen mask and a filter device, one end of the delivery hose is installed at the air inlet of the filter device, and the oxygen mask is installed on the air outlet of the filter device. The delivery hose is used to deliver oxygen, and the filter device is used to filter oxygen, and after filtering harmful substances, it is delivered to the person through the oxygen mask for breathing.

[0012] In one or more embodiments of the present invention, a mounting box is fixedly connected to the mounting plate, the medium storage tank is installed in the mounting box, a plurality of connecting pipes are arranged on the side wall of the medium storage tank, and the ends of the delivery hoses of the plurality of breathing components away from the filtering device are respectively installed on the connecting pipes, so that the oxygen generated by the oxygen generating medium can be delivered to the delivery hoses through the connecting pipes. A trigger-type switch door is installed on the mounting plate, and the breathing component is placed above the trigger-type switch door, so that the oxygen mask can automatically fall down after the trigger-type switch door is opened for use by passengers. A gas detector is installed at the bottom of the mounting plate, and the gas detector is used to detect the air quality in the elevator car. When the gas in the elevator car contains excessive smoke, the trigger-type switch door can be triggered to cause the oxygen mask to fall down.

[0013] In one or more embodiments of the present invention, the oxygen generating medium is an oxygen candle, which can generate oxygen when burning, thereby providing oxygen to the breathing assembly through the combustion of the oxygen candle. A trigger switch is provided between the oxygen candle and the delivery hose. When the trigger switch door is actuated to cause the oxygen mask to fall, the passenger pulls the oxygen mask, so that the delivery hose is pulled and the trigger switch is turned on, and the oxygen candle can be burned, thereby generating oxygen to be transported through the delivery hose. At the same time, the oxygen passes through a filter device to filter the chlorine gas generated during combustion, and then can be provided to the passenger through the oxygen mask. The ingredients of the oxygen candle include sodium chlorate, barium peroxide and potassium chlorate.

[0014] In one or more embodiments of the present invention, a pair of bases are fixedly connected to the bottom wall plate of the elevator car, a pair of rotating shafts are fixedly connected to the bottom of the driving gear and the first driven gear, and the pair of rotating shafts are respectively installed in a pair of bases in a rotating connection manner, and the rotating shafts are supported by the bases to ensure that the rotating shafts are stable when rotating on the bases, so that the driving gear and the first driven gear are stable when rotating, so that they can stably drive each other to rotate. A through hole is opened at the bottom of the rear side wall of the elevator car, and the first driven gear and the second driven gear are meshed and connected together through the through hole, so that the first driven gear can stably drive the second driven gear to rotate. It should be noted that, under normal circumstances, the movement of the elevator car is driven by the driving mechanism. Since the second driven gear is threadedly connected to the screw, the second driven gear needs to move up and down synchronously with the elevator car. Therefore, a synchronous gear needs to be provided between the second driven gear and the rotating part driven by the driving mechanism, so that the rotating part driven by the driving mechanism can drive the second driven gear to rotate through the synchronous gear, and can also drive the rotating part driven by the driving mechanism to rotate through the rotation of the second driven gear, so that the elevator car can be driven to move up and down by the rotation of the driving mechanism or the rotation of the second driven gear.

[0015] In one or more embodiments of the present invention, the manual drive member includes a clamping groove, which is fixedly connected to the driving gear, so that the driving gear can be driven to rotate by rotating the clamping groove. The clamping groove is arranged below the mounting plate, so that the manual drive assembly can be shielded by the mounting plate, so that the manual drive assembly will not contact the elevator passengers. A rotating handle is placed at the bottom of the elevator car, and one end of the rotating handle is fixedly connected with a sleeve joint for being sleeved with the clamping groove, and one end of the clamping groove away from the sleeve joint is fixedly connected with a clamping portion. By sleeve-fitting the sleeve joint at one end of the rotating handle into the clamping groove, the clamping groove can be driven to rotate by rotating the handle, thereby driving the driving gear to rotate, making the rotation of the driving gear easy, so that an ordinary adult can drive the driving gear to rotate by rotating the rotating handle. At the same time, a clamping portion is installed at one end of the rotating handle, and the clamping portion makes it easy for the elevator passengers to open the glass door that cannot be opened normally, so that the elevator passengers can get out of the elevator car when escaping. A plurality of sleeve rods are fixedly connected to the bottom of the elevator car, and the rotating handle is placed between the plurality of sleeve rods. The sleeve rods are used to limit the movement of the rotating handle, so that the position of the sleeve rods is restricted, so that the elevator passengers can take it easily.

[0016] In one or more embodiments of the present invention, a cover plate is detachably mounted on the bottom plate, a pair of sliding grooves are symmetrically provided on the side wall of the cover plate, a pair of clamping rods are slidably connected in the pair of sliding grooves, a pair of clamping grooves matching the sliding grooves are provided on the side wall of the bottom plate to which the cover plate is mounted, one end of the pair of clamping rods is placed in the clamping grooves, a compression spring is installed in the sliding grooves, the compression spring is installed at the end of the clamping rod away from the clamping grooves, a push plate is fixedly connected to the clamping rod, and a mounting groove is provided on the side of the clamping groove close to the cover plate. When the elevator abnormality traps the passengers in the elevator, the passengers need to save themselves by opening the cover plate, so that the rotating handle can be taken out and sleeved in the clamping groove to drive the driving gear to rotate by rotation. In order to facilitate the disassembly and assembly of the cover plate, the clamping rods slidably connected on the side wall of the cover plate cooperate with the clamping grooves provided on the bottom plate, and the disassembly and assembly can be achieved by clamping the clamping rods on the cover plate and the bottom plate. In order to facilitate the removal of the cover plate, the push plate can be pushed to drive the clamping rod to slide, so that the clamping rod is retracted into the sliding groove. When the end of the clamping rod placed in the clamping groove is fully retracted, the cover plate can be removed from the bottom plate. At the same time, the compression spring will be compressed when the clamping rod is retracted into the sliding groove. When installing the cover plate, the clamping rod is retracted into the sliding groove by pushing the push plate, and the clamping rod is installed at the clamping groove by the guidance of the installation groove. When the cover plate is completely installed in the bottom plate, the clamping rod corresponds to the clamping groove under the guidance of the installation groove, and the push plate is released. Under the action of the compression spring, the clamping rod can be pushed into the clamping groove, so that the cover plate is stably installed on the bottom plate through the clamping of the clamping groove, so that the cover plate is easy to disassemble and assemble. At the same time, it is necessary to set a protective piece on the surface of the bottom plate to facilitate disassembly and assembly, so as to prevent the push plate from being stepped on by the elevator passengers and to prevent impurities from entering the sliding groove.

[0017] In one or more embodiments of the present invention, a plurality of partitions are provided on the bottom wall of the elevator car, the partitions partitioning the area between the bottom plate and the bottom wall of the elevator car, and the area separated by the partitions is used for placing emergency items. The separated areas can be used to store items for emergency rescue, so that trapped people can take the emergency rescue items by opening the cover.

[0018] Compared with the prior art, the present invention has the following advantages: 1. The present invention is provided with a manual drive assembly. When an abnormal failure of the elevator causes people to be trapped in the elevator and the trapped people cannot contact the outside world for rescue in time, the trapped people can drive the elevator to move through the manual drive assembly, so that the elevator stops at the adjacent parking floor, so that the trapped people can escape by self-rescue; 2. The present invention is provided with an oxygen supply component. When a fire occurs and people are trapped in the elevator, when the smoke concentration in the elevator is high, it will automatically trigger the breathing component to fall down. The passengers pull the breathing component to make the oxygen generating medium generate oxygen for the passengers to use, thereby ensuring that the passengers can breathe normally, so that the people trapped in the elevator in the fire have enough time to escape; 3. The present invention provides an insulation layer in the elevator car, and the elevator glass door is provided with double-layer glass insulation, and flame retardant materials are provided between the double-layer glass layers, so as to avoid the high-temperature gas from causing harm to the personnel in the elevator car. When a fire occurs and personnel are trapped in the elevator, the high temperature outside will not cause harm to the personnel in the elevator, thereby buying time for the trapped personnel to escape.

DETAILED DESCRIPTION

[0022] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0023] like Figure 1 and Figure 4 As shown, an anti-fall home elevator suitable for villas in one embodiment of the present invention includes an elevator body 1, an oxygen supply component 2 and a manual drive component 3.

[0024] like Figure 1 and Figure 2As shown, the elevator body 1 includes an elevator car 11 and an elevator shaft. The elevator car 11 is installed in the elevator shaft. A glass door 12 is installed at the entrance and exit of the elevator car 11. The glass door 12 is used to close and open the entrance and exit of the elevator car 11. At the same time, the glass door 12 has good sealing when closed on the elevator car 11, which can prevent external gas from entering through the gap between the glass door 12 and the elevator car 11. A screw 13 is fixedly connected in the elevator shaft, and the screw 13 is a guide and driving member when the elevator car 11 runs in the elevator shaft.

[0025] like Fig.12 As shown, an insulation layer is provided on the outer wall of the elevator car 11, so that the temperature in the elevator car 11 will not be affected by the high temperature outside when a fire occurs, ensuring the safety of passengers in the elevator car 11. The glass door 12 includes a first glass layer 1201 and a second glass layer 1202, and a flame retardant material 1203 is provided between the first glass layer 1201 and the second glass layer 1202. The flame retardant material 1203 includes one or more combinations of sodium aluminum silicate, calcium aluminum phosphate, nitrogen phosphorus flame retardant and foaming flame retardant. The first glass layer 1201 and the second glass layer 1202 are both made of insulating glass, so that the glass door 12 has a good insulation effect. At the same time, in order to further ensure the insulation, a flame retardant material 1203 is arranged in the gap between the first glass layer 1201 and the second glass layer 1202. The flame retardant material 1203 can not only improve the insulation performance of the glass door 12, but also prevent the second glass layer 1202 arranged on the inner side from being heated, so as to make the second glass layer 1202 safe, thereby protecting the personnel in the elevator car 11. At the same time, when the first glass layer 1201 on the outside reaches its limit of withstanding high temperature, the first glass layer 1201 melts and cracks, so that the flame retardant material 1203 can be released, and the fire can be extinguished by the flame retardant material 1203. Since the flame retardant material 1203 will expand after being heated, the flame retardant material 1203 that expands after the first glass layer 1201 cracks can be sprayed out. In order to prevent the first glass layer 1201 and the second glass layer 1202 from being affected by overpressure after the flame retardant material 1203 expands due to heat, the placement amount of the flame retardant material 1203 needs to be combined with the spatial setting of the gap between the first glass layer 1201 and the second glass layer 1202.

[0026] like Figure 2 and Figure 4As shown, a driving mechanism 14 is installed on the rear side wall of the elevator car 11, and a rotating component is provided at the driving end of the driving mechanism 14 and is threadedly connected to the screw 13, so that the elevator car 11 can be driven by the driving mechanism 14 to move up and down on the screw 13. A limit rod 15 is fixedly connected in the elevator shaft, and a limit block 16 is fixedly connected to the rear side wall of the elevator car 11. The limit block 16 is slidably connected to the limit rod 15. Through the cooperation of the limit rod 15 and the limit block 16, the elevator car 11 is stable when moving up and down. A mounting plate 17 and a bottom plate 18 are fixedly connected to the inner side wall of the elevator car 11. The mounting plate 17 is arranged near the top of the elevator car 11, and the bottom plate 18 is arranged near the bottom. The mounting plate 17 is used to install the top components, and the bottom plate 18 is used to shield the bottom components.

[0027] like Figure 4 , Figure 7 and Figure 8 As shown, the oxygen supply assembly 2 includes a medium storage tank 21, which is arranged in the elevator car 11 and near the top. The medium storage tank 21 is provided with an oxygen generating medium 22, which generates oxygen after being triggered, so as to provide oxygen to the people in the elevator in extreme situations such as fire, so as to buy time for the people to escape. A breathing assembly is installed on the side wall of the medium storage tank 21, and a plurality of breathing assemblies are provided. The oxygen generated by the oxygen generating medium 22 is provided to the passengers through the breathing assembly, so that the passengers can breathe the oxygen generated by the oxygen generating medium 22 through the breathing assembly. At the same time, a plurality of breathing assemblies are provided, which can meet the use of normal family members, so that when there are more passengers in the elevator, there are enough breathing assemblies for the people to use. When a fire occurs and people are trapped in the elevator, smoke enters the elevator car 11, which poses a great threat to the safety of the people. In order to allow the people to breathe harmless oxygen, oxygen is generated through the oxygen generating medium 22, so that the people can breathe harmless oxygen through the breathing assembly, thereby ensuring that the people trapped in the elevator in the fire can breathe normally, and buying time for the people to escape.

[0028] like Figure 7 Combination Figure 8 as well as Fig. 9 As shown, the breathing assembly includes a delivery hose 24, an oxygen mask 25 and a filter device 26. One end of the delivery hose 24 is installed at the air inlet of the filter device 26, and the oxygen mask 25 is installed on the air outlet of the filter device 26. The delivery hose 24 is used to deliver oxygen, and the filter device 26 is used to filter oxygen, and after filtering harmful substances, it is delivered to the person through the oxygen mask 25 for breathing.

[0029] like Figure 7 Combination Figure 8As shown, a mounting box 27 is fixedly connected to the mounting plate 17, and the medium storage tank 21 is installed in the mounting box 27. A plurality of connecting pipes 23 are arranged on the side wall of the medium storage tank 21. The ends of the delivery hoses 24 of the plurality of breathing components away from the filter device 26 are respectively installed on the connecting pipes 23, so that the oxygen generated by the oxygen generating medium 22 can be delivered to the delivery hoses 24 through the connecting pipes 23. A trigger switch door 28 is installed on the mounting plate 17, and the breathing component is placed above the trigger switch door 28, so that the oxygen mask 25 can automatically fall down after the trigger switch door 28 is opened, so that the oxygen mask 25 can be used by the passengers. A gas detector 29 is installed at the bottom of the mounting plate 17. The gas detector 29 is used to detect the air quality in the elevator car 11. At the same time, the gas detector is electrically connected to the control system of the elevator. When the gas in the elevator car 11 contains excessive smoke, the trigger switch door 28 can be triggered to operate, so that the oxygen mask 25 falls down.

[0030] Preferably, the oxygen generating medium 22 is an oxygen candle, which can generate oxygen when burning, thereby providing oxygen to the breathing assembly through the combustion of the oxygen candle. A trigger switch is provided between the oxygen candle and the delivery hose 24. When the trigger switch door 28 is actuated to cause the oxygen mask 25 to fall, the passenger pulls the oxygen mask 25, so that the delivery hose 24 is pulled and the trigger switch is turned on, so that the oxygen candle can burn, thereby generating oxygen to be transported through the delivery hose 24. At the same time, the oxygen passes through the filter device 26 to filter the chlorine gas generated during the combustion, and then can be provided to the passenger through the oxygen mask 25. The components of the oxygen candle include sodium chlorate, barium peroxide and potassium chlorate.

[0031] like Fig.10 and Fig.11As shown, the manual drive assembly 3 includes a driving gear 31, which is rotatably mounted on the bottom of the elevator car 11, and a first driven gear 32 is rotatably mounted on the bottom of the elevator car 11, and the driving gear 31 and the first driven gear 32 are meshed and connected, and a second driven gear 33 is threadedly connected to the screw 13, and the second driven gear 33 and the first driven gear 32 are meshed and connected, and a manual driving member is provided on the driving gear 31, and the manual driving member is used to drive the driving gear 31 to rotate. When the driving gear 31 is driven to rotate by the manual driving member, the driving gear 31 can drive the first driven gear 32 to rotate, and the rotation of the first driven gear 32 can drive the second driven gear 33 to rotate. Since the second driven gear 33 is threadedly connected to the screw 13, the elevator car 11 can be moved up and down by the rotation of the second driven gear 33 on the screw 13. In order to enable passengers to take self-rescue measures after the elevator breaks down and stops operating, when communication is interrupted and passengers in the elevator cannot contact the outside world, they can manually rotate the drive gear 31 to drive the elevator car 11 to move up and down, so as to move the elevator car 11 to the entrance and exit corresponding to the floor, so that passengers can escape independently.

[0032] like Figure 2 Combination Figure 3 as well as Fig.10 As shown, a pair of bases 35 are fixedly connected to the bottom wall plate of the elevator car 11, and a pair of rotating shafts 36 are fixedly connected to the bottom of the driving gear 31 and the first driven gear 32. The pair of rotating shafts 36 are respectively installed in the pair of bases 35 in a rotating connection manner, and the rotating shafts 36 are supported by the bases 35 to ensure that the rotating shafts 36 are stable when rotating on the bases 35, so that the driving gear 31 and the first driven gear 32 are stable when rotating, so that they can stably drive each other to rotate. A through hole 34 is opened at the bottom of the rear side wall of the elevator car 11, and the first driven gear 32 and the second driven gear 33 are meshed and connected together through the through hole 34, so that the first driven gear 32 can stably drive the second driven gear 33 to rotate.

[0033] It should be noted that, under normal circumstances, the movement of the elevator car 11 is driven by the drive mechanism 14. Since the second driven gear 33 is threadedly connected to the screw 13, the second driven gear 33 needs to move up and down synchronously with the elevator car 11. Therefore, a synchronous gear needs to be provided between the second driven gear 33 and the rotating part driven by the drive mechanism 14, so that the rotating part driven by the drive mechanism 14 can drive the second driven gear 33 to rotate through the synchronous gear, and can also drive the rotating part driven by the drive mechanism 14 to rotate through the rotation of the second driven gear 33, so that the elevator car 11 can be driven to move up and down by the rotation of the drive mechanism 14 or the rotation of the second driven gear 33.

[0034] like Figure 4 and Fig.11 As shown, the manual drive member includes a clamping groove 37, which is fixedly connected to the drive gear 31, so that the drive gear 31 can be driven to rotate by rotating the clamping groove 37. The clamping groove 37 is arranged below the mounting plate 17, so that the manual drive assembly 3 can be shielded by the mounting plate 17, so that the manual drive assembly 3 will not contact the elevator passengers. A rotating handle 38 is placed at the bottom of the elevator car 11, and one end of the rotating handle 38 is fixedly connected to a sleeve joint 39 for sleeve engagement with the clamping groove 37, and one end of the clamping groove 37 away from the sleeve joint 39 is fixedly connected to a clamping portion 310. By sleeve-engaging the sleeve joint 39 at one end of the rotating handle 38 in the clamping groove 37, the clamping groove 37 can be driven to rotate by rotating the handle 38, thereby driving the drive gear 31 to rotate, making the rotation of the drive gear 31 easy, so that an ordinary adult can drive the drive gear 31 to rotate by rotating the rotating handle 38. At the same time, a clamping part 310 is installed at one end of the rotating handle 38, and the clamping part 310 makes it easy for the passengers to open the glass door 12 that cannot be opened normally, so that the passengers can escape from the elevator car 11. A plurality of sleeve rods 319 are fixedly connected to the bottom of the elevator car 11, and the rotating handle 38 is placed between the plurality of sleeve rods 319. The sleeve rods 319 limit the movement of the rotating handle 38, so that the position of the sleeve rods 319 is restricted, so that the passengers can take it easily.

[0035] like Figure 5 Combination Figure 6As shown, a cover plate 311 is detachably mounted on the bottom plate 18, a pair of sliding grooves 312 are symmetrically provided on the side wall of the cover plate 311, a pair of clamping rods 313 are slidably connected in the pair of sliding grooves 312, a pair of clamping grooves 315 matching the sliding grooves 312 are provided on the side wall of the bottom plate 18 to which the cover plate 311 is mounted, one end of the pair of clamping rods 313 is placed in the clamping grooves 315, a compression spring 314 is installed in the sliding grooves 312, the compression spring 314 is installed at one end of the clamping rod 313 away from the clamping groove 315, a push plate 317 is fixedly connected to the clamping rod 313, and a mounting groove 316 is provided on one side of the clamping groove 315 close to the cover plate 311. When the elevator is abnormal and traps the passengers in the elevator, and the passengers need to save themselves, they need to open the cover plate 311, so that the rotating handle 38 can be taken out and sleeved in the clamping groove 37, and the driving gear 31 can be rotated by rotating. In order to facilitate the assembly and disassembly of the cover plate 311, the clamping rod 313 slidably connected on the side wall of the cover plate 311 cooperates with the clamping groove 315 provided on the bottom plate 18, so that the assembly and disassembly can be achieved by clamping the clamping rod 313 on the cover plate 311 and the bottom plate 18. In order to facilitate the disassembly of the cover plate 311, the clamping rod 313 can be driven to slide by pushing the push plate 317, so that the clamping rod 313 is retracted into the sliding groove 312. When the end of the clamping rod 313 placed in the clamping groove 315 is completely retracted, the cover plate 311 can be removed from the bottom plate 18, and the compression spring 314 will be compressed when the clamping rod 313 is retracted into the sliding groove 312. When installing the cover plate 311, the clamping rod 313 is retracted into the sliding groove 312 by pushing the push plate 317, and the clamping rod 313 is installed at the clamping groove 315 by the guidance of the installation groove 316. When the cover plate 311 is completely installed in the base plate 18, the clamping rod 313 is made to correspond to the clamping groove 315 under the guidance of the installation groove 316, and the push plate 317 is released. Under the action of the compression spring 314, the clamping rod 313 can be pushed into the clamping groove 315, so that the cover plate 311 is stably installed on the base plate 18 through the clamping of the clamping groove 315, so that the cover plate 311 is easy to disassemble and assemble. At the same time, it is necessary to set a protective piece on the surface of the base plate 18 to facilitate disassembly and assembly, so as to prevent the push plate 317 from being stepped on by the passengers, and to prevent impurities from entering the sliding groove 312.

[0036] like Figure 4 and Figure 7 As shown, a plurality of partition plates 318 are provided on the bottom wall of the elevator car 11, and the partition plates 318 separate the area between the bottom plate 18 and the bottom wall of the elevator car 11, and the area separated by the partition plates 318 is used for placing emergency items. The separated areas can be used to store items for emergency rescue, so that the trapped people can take the emergency rescue items by opening the cover plate 311.

[0037] When in use, when people are trapped while riding the elevator and communication is interrupted, making it impossible for people to contact the outside world, the passengers can escape by themselves. First, the passengers remove the protective component set on the pushing plate 317, and push the pushing plate 317 to drive the clamping rod 313 to move, so that the clamping rod 313 slides out of the clamping groove 315, and then the cover plate 311 can be removed from the bottom plate 18, and then the rotating handle 38 is taken out from the bottom of the elevator car 11 and the sleeve joint 39 is sleeved on the clamping groove 37, and the rotating handle 38 can be turned to drive the driving gear 31 to rotate. When the driving gear 31 rotates, it drives the first driven gear 32 to rotate, and the rotation of the first driven gear 32 drives the second driven gear 33 to rotate. When the second driven gear 33 rotates, it can move up and down on the screw rod 13, so that the elevator car 11 can be driven up and down by the rotation of the second driven gear 33. At the same time, under the action of the synchronous gear, the rotation of the second driven gear 33 will drive the synchronous gear to rotate, and the rotation of the synchronous gear The rotating parts driven by the driving mechanism 14 are driven to rotate, so that the rotating parts driven by the driving mechanism 14 can be synchronously moved up and down on the screw 13, so that the up and down movement of the elevator car 11 is realized by the rotation of the driving gear 31, and the elevator car 11 is moved to the adjacent parking floor, and the trapped personnel can escape by opening the glass door 12; if people are trapped in the elevator due to fire, when the gas detector 29 detects that the smoke concentration in the elevator car 11 is high, it will cause the trigger switch door 28 to operate under the action of the elevator control system, so that the breathing component falls, and the passenger puts on the oxygen mask 25 and pulls the delivery hose 24 to trigger the switch, which will ignite the oxygen generating medium 22, so that the oxygen generating medium 22 produces oxygen, and the oxygen can be transported to the oxygen mask 25 through the delivery hose 24 for the personnel to breathe, thereby avoiding delay in causing harm to the trapped personnel. At the same time, the trapped personnel can use the manual drive component 3 to save themselves so as to get out of the elevator in time.
