Description

Technical Field

[0001] This invention relates to the field of construction elevator technology, and specifically to a semi-automatic construction elevator door. Background Technology

[0002] The statements herein provide only background information in relation to this invention and do not necessarily constitute prior art.

[0003] With the continuous innovation of construction technology, super high-rise building projects are becoming increasingly common. During the construction of such buildings, the vertical transportation of materials and personnel is a key factor affecting project progress. Construction elevators, as one of the main vertical transportation tools, directly impact construction speed, especially during the decoration and finishing stages.

[0004] To ensure the safety of personnel on each floor and inside the construction elevator, the construction elevator has independent floor doors and elevator car doors at each stop and in the elevator car, which open and close independently. This results in a cumbersome door-opening and closing procedure when the construction elevator stops at a construction floor (open elevator car door → lower safety partition → open floor door → load or unload materials or personnel → close floor door → lock floor door with latch → retract safety partition → close elevator car door). This cumbersome procedure leads to a long stop time per floor for each construction unit, directly affecting the elevator's transportation efficiency.

[0005] Therefore, the present invention provides a semi-automatic construction elevator door to solve the above problems. Summary of the Invention

[0006] The main objective of this invention is to provide a semi-automatic construction elevator door.

[0007] To achieve the above objectives, the technical solution of the present invention is as follows: a semi-automatic construction elevator door, comprising two sliding doors installed on the car, and safety partitions perpendicular to the sliding direction of the doors are provided on both sides of the car.

[0008] At the entrance of each floor, there are two normally closed landing doors that are parallel to the stair doors and can be deflected and opened in opposite directions.

[0009] Each floor's stairwell is also equipped with an actuation device;

[0010] The actuation device includes two pressure rods, which are elastically inserted on both sides of the stair opening and parallel to the direction of the stair door's translation; the pressure rods are in contact with the corresponding safety partitions.

[0011] The actuation device also includes an unlocking mechanism and a self-locking mechanism installed at the elevator entrance; a transmission assembly is installed on the car.

[0012] When the drive elevator door is opened, the transmission component can synchronously drive the two safety partitions to deflect from inside the car and extend into the elevator entrance of the corresponding floor, and press the corresponding pressure rods respectively, so as to drive the unlocking mechanism to release the normally closed state between the landing doors, allowing the two landing doors to deflect and open to the side away from the car.

[0013] When the drive door deflects and closes, the self-locking mechanism can automatically lock the relative position between the doors when they are closed.

[0014] Furthermore, the unlocking mechanism includes two door seats fixed on both sides of the stair opening, and each door seat has a vertical first rotating column that is rotatably installed inside. The outer wall of the first rotating column is fixedly connected to one side of the corresponding landing door.

[0015] A fixed plate is fixed inside the door seat. A first transmission block perpendicular to the pressure rod is slidably inserted on the fixed plate. A locking block is provided at the end of the first transmission block away from the car. A disc body is sleeved and fixed on the first rotating column. A slot that cooperates with the locking block is opened on the outer periphery of the disc body.

[0016] Two pressure rods are respectively inserted into the corresponding door seats. A second transmission block is coaxially set at one end of the pressure rod in the corresponding door seat. The second transmission block is pressed and engaged with the corresponding first transmission block.

[0017] When the safety partition presses against the corresponding pressure bar, it drives the second transmission block to squeeze the corresponding first transmission block, forcing the first transmission block to disengage the locking block from the slot, allowing the corresponding landing door to deflect away from the car.

[0018] Furthermore, the bottom wall of the door seat is provided with an insertion hole, the bottom of the first rotating post is inserted into the insertion hole, and a first torsion spring is sleeved on the outside of the first rotating post. The two ends of the first torsion spring are respectively connected to the outer wall of the first rotating post and the wall of the insertion hole.

[0019] When the doors are normally closed, the first torsion spring is in a compressed state.

[0020] When the doors are open, the first torsion spring is in a non-deformed state.

[0021] Furthermore, the first transmission block has a through groove for the second transmission block to pass through, and a first pressure-bearing slope is provided on one side of the groove opening. The outer side of the second transmission block has a first groove that can cross-engage with the through groove, and a pressure-applying slope that slides and presses against the first pressure-bearing slope on one side of the groove opening.

[0022] When the second transmission block does not press against the corresponding first transmission block, the second transmission block engages with the first transmission block through the groove in a cross-shaped manner.

[0023] When the second transmission block presses against the corresponding first transmission block, the second transmission block presses against the first pressure-bearing slope through the pressure slope, forcing the first transmission block to drive the locking block out of the locking groove. At this time, the first groove and the through groove are misaligned.

[0024] Furthermore, a first spring is sleeved on the outer side of the pressure rod, and the two ends of the first spring are respectively connected to the end side wall of the second transmission block and the corresponding inner wall of the door seat. When the second transmission block presses against the corresponding first transmission block, the first spring is stretched and deformed.

[0025] A second spring is provided between the end of the first transmission block near the car and the inner wall of the door seat. When the first transmission block drives the locking block to disengage from the locking slot, the second spring is compressed and deformed.

[0026] Furthermore, the door seat is elastically provided with a movable block that can move relative to the first transmission block in the direction of movement. The second transmission block is coaxially fixed with a connecting rod at the end away from the pressure rod. A pressure block is provided on the side of the connecting rod away from the second transmission block. The movable block has a first slot for the pressure block to be inserted on the side facing the first transmission block. One side of the opening of the first slot has a second pressure slope that slides and presses against the pressure block. The movable block has a second slot that engages with the pressure block. The second slot is connected to the side of the first slot near the car.

[0027] Furthermore, a first telescopic rod is provided between the end of the moving block near the car and the inner wall of the door seat, and a third spring is sleeved on the outside of the first telescopic rod;

[0028] When the pressure block squeezes the second pressure slope, it forces the moving block to move closer to the car, and the first telescopic rod and the third spring are compressed and deformed.

[0029] When the pressure block is engaged in the second slot, the first telescopic rod and the third spring are in a non-deformed state.

[0030] Furthermore, the self-locking mechanism includes a first transmission gear sleeved and fixed to the outside of the first rotating column, and a limiting groove in the shape of an eighth of a circle is fixed in the circumference of the first rotating column inside the door seat. The limiting groove is located outside the first transmission gear and between the first transmission block and the moving block.

[0031] A limiting block that can move relative to the limiting groove is elastically provided in the limiting groove. A second transmission gear that can move and mesh with the first transmission gear is rotatably provided on the limiting block. A third transmission gear that can mesh with the second transmission gear is elastically rotatably provided in the door seat on the side of the limiting groove away from the first transmission gear. A first bevel tooth is concentrically fixed on the third transmission gear. A cylinder parallel to the first transmission block is rotatably inserted into the fixed plate. A second bevel tooth that mates with the first bevel tooth is provided at one end of the cylinder. A screw is threaded into the other end of the cylinder. A push plate that can push the moving block to move closer to the car is fixed at one end of the screw. A second telescopic rod is provided between the push plate and the fixed plate.

[0032] When the landing door is deflected and opened, the landing door drives the first rotating column, the first transmission gear, and the second transmission gear to rotate. The second transmission gear on the limit block stays at the end of the limit groove near the car.

[0033] During the deflection and closure of the landing door, the landing door drives the first rotating column, the first transmission gear, and the second transmission gear to rotate. Under the limiting action of the limiting block and the limiting groove, the second transmission gear can move from one end of the limiting groove near the car to the other end to engage with the third transmission gear. This allows the bevel gear to drive the cylinder in conjunction with the screw to push the push plate to move the moving block towards the car, causing the pressure block to disengage from the second slot and return to the first slot.

[0034] When the landing door deflects parallel to the stair door, the slot rotates synchronously with the disc to a position where the card block can engage.

[0035] Furthermore, a fourth spring is provided in the limiting groove. The two ends of the fourth spring are respectively connected to the outer wall of the limiting block and the corresponding groove wall of the limiting groove. When the limiting block moves in the limiting groove towards the direction of the third transmission gear, the fourth spring is compressed and deformed.

[0036] The inner bottom wall of the gate seat has a spring hole, the bottom of the axle of the third transmission gear is inserted into the spring hole, and a second torsion spring is sleeved on the outer side of the axle of the third transmission gear. The two ends of the second torsion spring are respectively connected to the outer wall of the axle of the third transmission gear and the corresponding hole wall of the spring hole.

[0037] Furthermore, the transmission assembly includes two second rotating columns that are vertically arranged on both sides of the bottom of the car. One side of the safety partition is fixed to the outside of the corresponding second rotating column. A fourth transmission gear is sleeved and fixed at the top of the second rotating column. A rack is provided on the top of the side of the elevator door away from the elevator opening, which is parallel to its translation direction and cooperates with the corresponding fourth transmission gear.

[0038] The maximum deflection angle of the safety partition is 180 degrees;

[0039] When the elevator doors are closed, the safety partition is located inside the car and parallel to the side wall of the car;

[0040] After the stairwell door is opened, the safety partition is located inside the corresponding stairwell opening and is parallel to the side wall of the corresponding stairwell opening.

[0041] The beneficial effects of this invention are reflected in:

[0042] The semi-automatic construction elevator door of this invention, through the addition of a transmission component between the safety partition of the car and the elevator door, and the addition of an action device at the entrance of each floor, allows construction personnel or materials to automatically move from the car to the corresponding floor by relying solely on the translational action of the elevator door when it opens. When construction personnel or materials enter the corresponding floor, the door automatically locks itself in place by relying solely on the deflection action of the door when it closes. This significantly shortens the opening and closing time of the construction elevator, reduces the elevator's single-trip transport time, increases the daily number of trips, and ultimately improves elevator transport efficiency, making a significant contribution to shortening the construction period and reducing construction costs.

[0043] The semi-automatic construction elevator door of the present invention realizes semi-automation of elevator access during construction, reduces manual operation, reduces ineffective labor output, and significantly improves safety performance and standardized visual appearance.

[0058] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. Obviously, the described embodiments are only a part of the embodiments of the invention, and not all of them. Unless otherwise specified, the embodiments and features described in this application can be combined with each other. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0059] Please combine Figures 1 to 11 .

[0060] A semi-automatic construction elevator door includes two sliding doors 3 installed on a car 1. Safety partitions 4, which are perpendicular to the sliding direction of the doors 3, are provided on both sides of the car 1.

[0061] At each floor's stairwell 2, there are two normally closed landing doors 5 that are parallel to the stairwell door 3 and can be deflected and opened in opposite directions.

[0062] There are also two actuation devices at the entrances of the stairs on each floor.

[0063] The actuation device includes two pressure rods 15 and an unlocking mechanism. The two pressure rods 15 are elastically inserted on both sides of the ladder opening 2 and are parallel to the translational direction of the ladder door 3. The pressure rods 15 are in contact with the corresponding safety partitions 4.

[0064] The actuation device also includes an unlocking mechanism and a self-locking mechanism installed in the elevator entrance 2, and a transmission component is installed on the car 1.

[0065] When the drive door 3 is opened, the transmission assembly can synchronously drive the two safety partitions 4 to deflect from inside the car 1 and extend into the corresponding floor's stairwell 2, and press the corresponding pressure rods 15 respectively, so as to drive the unlocking mechanism to release the normally closed state between the landing doors 5, allowing the two landing doors 5 to deflect and open to the side away from the car 1.

[0066] When the drive door 5 deflects and closes, the self-locking mechanism can automatically lock the relative position of the door 5 when it is closed, so that the door 5 returns to the normally closed state parallel to the stair door 3.

[0067] In practice, when the elevator moves to the selected floor, when the control drives the two elevator doors 3 to slide open, the movement of the elevator doors 3 can cause the two safety partitions 4, which were originally parallel to each other on both sides of the car wall in the car 1, to deflect outwards and extend into the elevator entrance 2 of the corresponding floor. They then press the corresponding pressure rods 15 in the elevator entrance 2, thereby driving the unlocking mechanism through the pressure rods 15, releasing the normally closed state between the floor doors 5, and allowing the two floor doors 5 to automatically deflect and open to the side away from the car 1 so that construction personnel or materials can enter the corresponding floor.

[0068] After construction personnel or materials enter the corresponding floor, the two elevator doors 3 are manually driven to return to a position parallel to the elevator doors 3. At this time, the self-locking mechanism can automatically lock the relative position of the landing doors 5 when they are closed, so that the landing doors 5 return to the normally closed state parallel to the elevator doors 3. Then, the two elevator doors 3 are controlled to slide and close. The movement of the elevator doors 3 can be transmitted through the transmission components to make the safety partition 4 in the elevator entrance 2 automatically return to the positions on both sides of the car 1 for subsequent movement and use of the construction elevator.

[0069] The advantage of this design is that when construction personnel or materials need to enter the corresponding floor from the car 1, the sliding action of the elevator door 3 when it opens can automatically achieve the deflection and placement of the safety partition 4 into the elevator entrance 2 of the corresponding floor and the automatic opening of the corresponding floor door 5. When construction personnel or materials enter the corresponding floor, the deflection action of the floor door 5 when it closes can automatically lock the position of the closed floor door 5. This can significantly shorten the opening and closing time of the construction elevator, reduce the single trip transportation time of the elevator, increase the daily number of trips of the elevator, and ultimately improve the elevator transportation efficiency, which makes a significant contribution to shortening the construction period and reducing construction costs.

[0070] It should be noted that the elevator door 3 of the car 1 in this application adopts an automatic opening and closing mechanism, which can be divided into three main categories: DC voltage regulation speed control drive, AC frequency regulation speed control drive combined with synchronous toothed belt drive, and water magnetic synchronous motor drive combined with synchronous toothed belt drive. Among them, the DC voltage regulation speed control drive and transmission mechanism is the most common. Its principle is to utilize the excellent voltage regulation and speed control performance and simple commutation characteristics of the DC motor, and realize the automatic opening and closing function through belt pulley reduction and mechanism transmission.

[0071] In one embodiment, the unlocking mechanism includes two door seats 6 fixed on both sides of the stair opening 2, and each door seat 6 has a vertical first rotating column 11 that is rotatably installed inside it. The outer wall of the first rotating column 11 is fixedly connected to one side of the corresponding landing door 5.

[0072] A fixed plate 8 is fixed inside the door seat 6. A first transmission block 9 perpendicular to the pressure rod 15 is slidably inserted on the fixed plate 8. A locking block 10 is provided at the end of the first transmission block 9 away from the car 1. A disc body 12 is sleeved and fixed on the first rotating column 11. A slot 13 that cooperates with the locking block 10 is opened on the outer periphery of the disc body 12.

[0073] Two pressure rods 15 are respectively inserted into the corresponding door seat 6. The end of the pressure rod 15 located in the corresponding door seat 6 is coaxially provided with a second transmission block 14. The second transmission block 14 is pressed and engaged with the corresponding first transmission block 9.

[0074] When the safety partition 4 presses against the corresponding pressure bar 15, it drives the second transmission block 14 to squeeze the corresponding first transmission block 9, forcing the first transmission block 9 to drive the locking block 10 to disengage from the locking slot 13, allowing the corresponding landing door 5 to deflect away from the car 1.

[0075] Thus, when the elevator door 3 slides open, the elevator door 3 drives the safety partition 4 to deflect into the elevator opening 2 and press the corresponding pressure rod 15. The pressure rod 15 drives the second transmission block 14 to squeeze the corresponding first transmission block 9, forcing the first transmission block 9 to move closer to the car 1, thereby causing the locking block 10 to disengage from the locking slot 13, releasing the lock on the position of the plate 12, and then the landing door 5 can be deflected to the side away from the car 1 by the first rotating column 11.

[0076] It should be added that the maximum deflection angle of the landing door 5 in this application is ninety degrees, and the door seat 6 is provided with a door placement groove 7 for the landing door 5 to be accommodated after it is opened.

[0077] In one embodiment, the bottom wall of the door seat 6 is provided with an insertion hole (not shown), the bottom of the first rotating post 11 is inserted into the insertion hole, and a first torsion spring (not shown) is sleeved on the outside of the first rotating post 11. The two ends of the first torsion spring are respectively connected to the outer wall of the first rotating post 11 and the wall of the insertion hole.

[0078] When the fifth door is normally closed, the first torsion spring is in a compressed state.

[0079] When the fifth door is open, the first torsion spring is in a non-deformed state.

[0080] Thus, when the card block 10 disengages from the card slot 13 and releases the lock on the position of the disc body 12, the first rotating column 11 can automatically deflect and open to the side away from the car 1 under the release action of the first torsion spring, so as to realize the automatic opening of the landing door 5 after the elevator door 3 is opened and the safety partition 4 deflects and extends into the elevator opening 2.

[0081] In one embodiment, the first transmission block 9 has a through groove 18 through which the second transmission block 14 passes vertically. The groove 18 has a first pressure-bearing slope 19 on one side. The second transmission block 14 has a first groove 16 on the outside that can cross-engage with the through groove 18. The groove 16 has a pressure-applying slope 17 on one side that slides and presses against the first pressure-bearing slope 19.

[0082] When the second transmission block 14 does not press against the corresponding first transmission block 9, the second transmission block 14 cross-engages with the through groove 18 of the first transmission block 9 through the first groove 16.

[0083] When the second transmission block 14 presses against the corresponding first transmission block 9, the second transmission block 14 presses against the first pressure-bearing slope 19 through the pressure slope 17, forcing the first transmission block 9 to drive the locking block 10 to disengage from the locking groove 13. At this time, the first groove 16 and the through groove 18 are misaligned.

[0084] Thus, when the safety partition 4 does not enter the ladder opening 2 and press against the pressure rod 15, the second transmission block 14 does not press against the corresponding first transmission block 9. The second transmission block 14 is in a cross-shaped embrace with the first transmission block 9 through the first groove 16 and the through groove 18 of the first transmission block 9. At this time, the locking block 10 is engaged in the locking groove 13.

[0085] When the safety partition 4 enters the stairwell 2 and presses against the pressure rod 15, the pressure rod 15 drives the second transmission block 14 to move, causing the pressure slope 17 to press against the first pressure slope 19 until the first groove 16 and the through groove 18 are misaligned. This causes the first transmission block 9 to move towards the car 1, so that the locking block 10 is disengaged from the locking groove 13, releasing the lock on the position of the disc body 12, and thus allowing the first rotating column 11 to drive the landing door 5 to open under the elastic force release of the first torsion spring.

[0086] In one embodiment, a first spring (not shown) is sleeved on the outside of the pressure rod 15. The two ends of the first spring are respectively connected to the end side wall of the second transmission block 14 and the corresponding inner wall of the door seat 6. When the second transmission block 14 presses the corresponding first transmission block 9, the first spring is stretched and deformed.

[0087] A second spring (not shown) is provided between the end of the first transmission block 9 near the car 1 and the inner wall of the door seat 6. When the first transmission block 9 drives the locking block 10 to disengage from the locking groove 13, the second spring is compressed and deformed.

[0088] Thus, the stretching deformation of the first spring allows the pressure rod 15 to assist the second transmission block 14 in reversing its movement back to its cross-engaged state with the first transmission block 9 when it is not pressed by the safety partition 4 and the pressure block 25 disengages from the second slot 22 and returns to the first slot 21, thereby providing clearance for the first transmission block 9 to move back in reverse.

[0089] The compression deformation of the second spring can help the first transmission block 9 move in the opposite direction when the second transmission block 14 moves back to the cross-engaged state with the first transmission block 9, so that the locking block 10 can be re-engaged into the locking slot 13, thus locking the position of the disc body 12, that is, locking the position of the door 5 after closing.

[0090] In one embodiment, a movable block 20 that can move relative to the first transmission block 9 in the moving direction is elastically provided in the door seat 6. A connecting rod 24 is coaxially fixed at the end of the second transmission block 14 away from the pressure rod 15. A pressure block 25 is provided on the side of the connecting rod 24 away from the second transmission block 14. The movable block 20 has a first slot 21 for the pressure block 25 to be inserted on the side facing the first transmission block 9. A second pressure slope 23 that slides and presses against the pressure block 25 is provided on one side of the opening of the first slot 21. A second slot 22 that engages with the pressure block 25 is provided in the movable block 20. The second slot 22 is connected to the side of the first slot 21 near the car 1.

[0091] Thus, when the safety partition 4 enters the stairwell 2 and presses against the pressure rod 15, the pressure rod 15 drives the second transmission block 14 to move. This not only causes one end of the first transmission block 9 to drive the locking block 10 out of the slot 13, releasing the lock on the position of the disc body 12, allowing the first rotating column 11 to drive the landing door 5 to open under the release of the elastic force of the first torsion spring, but also causes the second transmission block 14 to drive the pressure block 25 to squeeze the second pressure slope 23 through the connecting rod 24, forcing the moving block 20 to move horizontally towards the car 1 to avoid the pressure block 25 so that the pressure block 25 can enter the first slot 21.

[0092] When the pressure block 25 is fully inserted into the first slot 21, the moving block 20 can move in the opposite direction to the pressure block 25 under the action of the rebound force, so that the pressure block 25 is inserted into the second slot 22, thereby effectively maintaining the misalignment between the second transmission block 14 and the first transmission block 9.

[0093] In one embodiment, a first telescopic rod 26 is provided between the end of the movable block 20 near the car 1 and the inner wall of the door seat 6, and a third spring (not shown) is sleeved on the outside of the first telescopic rod 26.

[0094] When the pressure block 25 presses against the second pressure slope 23, it forces the moving block 20 to move closer to the car 1, causing the first telescopic rod 26 and the third spring to compress and deform.

[0095] When the pressure block 25 is engaged in the second slot 22, the first telescopic rod 26 and the third spring are in a non-deformed state.

[0096] In this way, the first telescopic rod 26 can be used to install and position the moving block 20 in the door seat 6. At the same time, the cooperation between the first spring and the first telescopic rod 26 can realize automatic locking or automatic unlocking after the second transmission block 14 and the first transmission block 9 are misaligned.

[0097] In one embodiment, the self-locking mechanism includes a first transmission gear 27 sleeved and fixed to the outside of the first rotating column 11. A limiting groove 28 in the shape of an eighth of a circle is fixed in the circumference of the first rotating column 11 inside the door seat 6. The limiting groove 28 is located outside the first transmission gear 27 and between the first transmission block 9 and the moving block 20. The limiting groove 28 is fixed to the fixed plate 8 by a support rod.

[0098] A limiting block 29 is elastically provided in the limiting groove 28, which can move relative to the groove. A second transmission gear 30 is rotatably provided on the limiting block 29, which can move and mesh with the first transmission gear 27 in the circumferential direction. A third transmission gear 31 that can mesh with the second transmission gear 30 is elastically rotatably provided in the door seat 6 located on the side of the limiting groove 28 away from the first transmission gear 27. A first bevel tooth 32 is concentrically fixed on the third transmission gear 31. A cylinder 33 parallel to the first transmission block 9 is rotatably inserted on the fixed plate 8. A second bevel tooth 34 that cooperates with the first bevel tooth 32 is provided at one end of the cylinder 33. A screw 36 is threaded into the other end of the cylinder 33. A push plate 35 that can push the moving block 20 to move closer to the car 1 is fixed at one end of the screw 36. A second telescopic rod 37 is provided between the push plate 35 and the fixed plate 8.

[0099] When the landing door 5 is deflected and opened, the landing door 5 drives the first rotating column 11, the first transmission gear 27, and the second transmission gear 30 to rotate. The second transmission gear 30 on the limiting block 29 stays at the end of the limiting groove 28 near the car 1.

[0100] During the deflection and closure of the drive landing door 5, the landing door 5 drives the first rotating column 11, the first transmission gear 27, and the second transmission gear 30 to rotate. Under the limiting action of the limiting block 29 and the limiting groove 28, the second transmission gear 30 can move from one end of the limiting groove 28 near the car 1 to the other end to engage with the third transmission gear 31. The bevel drive cylinder 33, in conjunction with the screw 36, causes the push plate 35 to push the moving block 20 towards the car 1, so that the pressure block 25 disengages from the second slot 22 and returns to the first slot 21.

[0101] When the landing door 5 deflects parallel to the stair door 3, the slot 13 rotates synchronously with the disc body 12 to a position where the card block 10 can engage.

[0102] Thus, when the landing door 5 is deflected and opened, the landing door 5 drives the first rotating column 11, the first transmission gear 27, and the second transmission gear 30 to rotate. The second transmission gear 30 on the limiting block 29 stays at the end of the limiting groove 28 near the car 1. At this time, the second transmission gear 30 does not contact or mesh with the third transmission gear 31, so the push plate 35 remains stationary.

[0103] During the deflection and closure of the landing door 5, the landing door 5 drives the first rotating column 11, the first transmission gear 27, and the second transmission gear 30 to rotate. Under the meshing action and the limiting action of the limiting block 29 and the limiting groove 28, the second transmission gear 30 moves from one end of the limiting groove 28 near the car 1 to the other end to mesh with the third transmission gear 31, thereby driving the third transmission gear 31 to rotate. The third transmission gear 31 drives the first bevel gear 32 and the second bevel gear 34 to drive the cylinder 33 to rotate, so that the cylinder 33 and the screw 36 interact with each other through the thread. Under the limiting action of the second telescopic rod 37, the push plate 35 moves. Block 20 is pushed to move closer to the car 1, so that the second slot 22 disengages from the pressure block 25, and the pressure block 25 returns to the first slot 21, releasing the locking state between the second slot 22 and the pressure block 25. Thus, when the pressure rod 15 can move in the reverse direction under the action of the first spring force, the second transmission block 14 and the first transmission block 9 return to the cross-clamping state, providing clearance space for the reverse return movement of the first transmission block 9, so that the first transmission block 9 can move in the reverse direction under the action of the second spring force, so that the locking block 10 is locked into the locking groove 13 of the disc 12, locking the position of the landing door 5 after it is closed.

[0104] In one embodiment, a fourth spring (not shown) is provided in the limiting groove 28. The two ends of the fourth spring are respectively connected to the outer wall of the limiting block 29 and the corresponding groove wall of the limiting groove 28. When the limiting block 29 moves in the limiting groove 28 in the direction close to the third transmission gear 31, the fourth spring is compressed and deformed.

[0105] The bottom wall of the portal seat 6 has a spring hole. The bottom of the axle of the third transmission gear 31 is inserted into the spring hole (not shown in the figure). A second torsion spring (not shown in the figure) is sleeved on the outside of the axle of the third transmission gear 31. The two ends of the second torsion spring are respectively connected to the outer wall of the axle of the third transmission gear 31 and the corresponding hole wall of the spring hole.

[0106] Thus, when the landing door 5 is closed, the second transmission gear 30 engages with the first transmission gear 27, causing the second transmission gear 30 to move away from the car 1 via the limiting block 29 towards the limiting groove 28. This enables the second transmission gear 30 to engage with the third transmission gear 31 (this process gradually compresses the fourth spring and deforms the second torsion spring), thereby causing the push plate 35 to push the moving block 20. Utilizing this compression force, when the landing door 5 is closed, the release of the fourth spring force pushes the limiting block 29 in the limiting groove 28 to move in the opposite direction to its initial position, allowing the second transmission gear 30 to disengage from the third transmission gear 31 and return to its initial position along with the limiting block 29. Simultaneously, the release of the compression force of the second torsion spring drives the cylinder 33 to rotate in the opposite direction, indirectly causing the push plate 35 to move away from the moving block 20 and disengage from it. The moving block 20 can then return to its initial position (the second pressure slope 23 is located directly below the pressure block 25) under the restoring action of the third spring force.

[0107] In one embodiment, the transmission assembly includes two second rotating columns 42 that are vertically arranged on both sides of the bottom of the car 1. One side of the safety partition 4 is fixed to the outside of the corresponding second rotating column 42. A fourth transmission gear 38 is sleeved and fixed at the position of the second rotating column 42 near the top. A rack 39 is provided on the top of the side of the door 3 away from the door opening 2, which is parallel to its translation direction and cooperates with the corresponding fourth transmission gear 38.

[0108] The maximum deflection angle of safety partition 4 is 180 degrees.

[0109] When the elevator door 3 is closed, the safety partition 4 is located inside the car 1 and parallel to the side wall of the car 1.

[0110] After the stair door 3 is opened, the safety partition 4 is located inside the corresponding stair opening 2 and is parallel to the side wall of the corresponding stair opening 2.

[0111] It should be noted that the ladder door 3 is provided with a sliding groove (not shown) for the rack 39 to slide and engage. When the ladder door 3 is opened, the front end of the rack 39 will first contact the fourth transmission gear 38. However, under the resistance of the fourth transmission gear 38, the ladder door 3 continues to open and move relative to the rack 39 through the sliding groove until the rack 39 is relatively displaced to the predetermined limit position in the sliding groove. At this time, the translation of the ladder door 3 when it continues to open can drive the fourth transmission gear 38 and the second rotating column 42 to rotate through the rack 39, so that the safety partition 4 deflects into the ladder opening 2, avoiding the ladder door 3 from interfering with the deflection of the safety partition 4 into the ladder opening 2.

[0112] When the elevator door 3 is closed, the elevator door 3 will not move synchronously with the rack 39 at the beginning of its translation. During this period, the elevator door 3 will push the corresponding safety partition 4 to deflect in the opposite direction until the rack 39 is located at one end in the slide groove. At this time, the elevator door 3 can drive the fourth transmission gear 38 to rotate through the rack 39, so that the fourth transmission gear 38 can drive the corresponding safety partition to deflect further and return to the car 1 through the second rotating column 42.

[0113] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.

[0114] It should be noted that if the embodiments of the invention involve directional indicators (such as up and down), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0115] Furthermore, the meaning of "and / or" throughout the text includes three parallel solutions. Taking "A and / or B" as an example, it includes solution A, solution B, or a solution that satisfies both A and B. Additionally, if the embodiments of the invention involve descriptions such as "first," "second," etc., these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, features defined with "first" or "second" can explicitly or implicitly include at least one of those features. Furthermore, "multiple" refers to two or more. Moreover, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of a person skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by the invention.
