Description
Technical Field
[0001] This invention belongs to the field of light curtain technology for arc-shaped elevator doors, and specifically relates to a molding structure for an arc-shaped elevator door light curtain. Background Technology
[0002] As living standards and other aspects of construction continue to improve, passengers are demanding more and more comfort. As more and more circular elevators are being built in villas and shopping malls, elevator safety issues are becoming increasingly prominent. Passengers are placing higher demands on the safety and reliability of circular elevator door protection devices. A light curtain forming structure for curved elevator doors is a safety protection device specifically designed for curved elevator doors. Its core consists of two symmetrically arranged light curtain bodies, which are fixed to the upper and lower sides of the door frame by light curtain brackets. Connector cables are installed at the upper end of the light curtain bodies to achieve electrical connection. This structure forms a dense protective light curtain by emitting and receiving infrared light. When the light is blocked, the elevator door reverses and opens immediately. The rear end of its outer bracket adopts a bent and inclined design, which not only adapts to the contour of the curved door but also enhances the structural stability. It also has the characteristics of low modification cost, wide applicability, and good sensing effect, which can effectively improve the safety performance of curved elevator doors.
[0003] However, traditional devices still have the following problems when in use: Patent application publication number CN206985490U discloses an elevator light curtain structure. The installation structure of this elevator light curtain allows for the installation of multiple light curtains, improving the sensitivity of detection. Furthermore, the connection and disassembly of the light curtain to the car door are simple and convenient.
[0004] In existing technologies, light curtains are usually installed in a left-right opposing method, which is suitable for flat elevator door areas. However, in curved elevators, the door edges are not on the same plane during the opening and closing process, which can cause the opposing light curtain to malfunction, so it cannot be directly applied. Therefore, we propose a light curtain forming structure for arc-shaped elevator doors to solve the problem that existing light curtains cannot be directly applied to arc-shaped elevators, enabling the light curtain to be directly applied to arc-shaped elevators.
[0005] This invention designs a light curtain transmitter and receiver with the same curvature as a circular elevator. Installed on the upper and lower sides of the elevator door, it is unaffected by the opening and closing of the elevator door and can effectively detect the elevator door area, perfectly solving the problem of safety detection in the circular elevator door area and ensuring the safe operation of the elevator.

[0030] To make the objectives, technical solutions, and advantages of the present invention clear and complete, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of the present invention, and are merely illustrative of the embodiments of the present invention. They are not intended to limit the embodiments of the present invention. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0031] Example 1, please refer to Figures 1 to 11This invention provides a technical solution for a light curtain forming structure for an arc-shaped door elevator: it includes an arc-shaped door elevator body 1, a transmitter 2 fixedly installed above the elevator door, a mounting frame 3 fixedly connected below the elevator door, a receiver 21 movably contacting the interior of the mounting frame 3, a control box 22 fixedly connected to the lower interior of the arc-shaped door elevator body 1, a cable connecting the outer wall of one end of the control box 22 to the outer wall of one end of the receiver 21, a cable connecting the outer wall of one end of the control box 22 to the outer wall of one end of the transmitter 2, an installation groove 24 formed on the top outer wall of the mounting frame 3, sliding grooves 25 formed on both sides of the installation groove 24, a sliding rod 26 slidably connected inside the sliding groove 25, a movable insertion between the interior of the installation groove 24 and the outer wall of the receiver 21, and a screw rod 23 fixedly connecting the outer walls of both sides of the receiver 21 and the top outer wall of the sliding rod 26.
[0032] Since the receiver 21 and transmitter 2 are set on the upper and lower sides of the elevator door according to the shape of the curved elevator door, the accuracy of the use of transmitter 2 and receiver 21 is effectively guaranteed, the error in the operation of transmitter 2 and receiver 21 is reduced, the timeliness and accuracy of signal transmission are guaranteed, and reliable signal support is provided for the normal operation of the curved elevator door.
[0033] In Example 2, based on Example 1, a fixed shell 6 is fixedly connected to the outer wall of the top of the shelf 51. A return spring 61 is fixedly connected to one side of the inner wall of the two fixed shells 6. A plug rod 62 is fixedly connected to the outer wall of one end of the return spring 61. The outer wall of the plug rod 62 is slidably connected to the inside of the fixed shell 6. The outer wall of one end of the plug rod 62 is movably inserted into the outer wall of the turntable 55.
[0034] When the two insert rods 62 are inserted into the turntable 55 and the turntable 71 respectively, the rotating rod 72 and the rotating rod 56 can be limited, preventing the rotating rod 72 and the rotating rod 56 from rotating. This increases the stability of the rotating rod 56 and the rotating rod 72, further improving the stability of the receiver 21 inside the mounting frame 3 and preventing the tightening rope 58 and the tightening rope 78 from loosening and affecting the stability of the receiver 21.
[0035] In Example 3, based on Example 2, an insertion hole 54 is provided on the outer wall of one end of the receiver 21. An insertion plate 53 is movably inserted into the insertion hole 54. An elastic block 52 is fixedly connected to the outer wall of one side of the insertion plate 53. The outer wall of one side of the elastic block 52 is fixedly connected to one side of the inner wall of the mounting groove 24. A groove 5 is provided on the upper part of the outer wall of one end of the mounting bracket 3. A shelf 51 is fixedly connected to the inner wall of the groove 5. A base is fixedly connected to the lower part of the inner wall of the groove 5. A rotating rod 56 is rotatably connected inside the base. A tightening rope 58 is wound around the outer wall of the rotating rod 56. The outer wall of one end of the tightening rope 58 passes through the interior of the mounting groove 24 and is fixedly connected to the outer wall of one side of the insertion plate 53. A handle 57 is fixedly connected to the outer wall of the top of the rotating rod 56. A turntable 55 is fixedly connected to the outer wall of the top of the handle 57.
[0036] By tightening the tightening rope 58, the receiver 21 can be slightly adjusted inside the mounting slot 24 to ensure that the receiver 21 and the transmitter 2 always remain parallel and aligned. The tension of the tightening rope can be adjusted according to the actual situation to adapt to different installation environments, compensate for minor errors in the installation process, and keep the receiver 21 in the appropriate position.
[0037] In Example 4, based on Example 3, a second insertion hole 75 is provided on the outer wall of the other end of the receiver 21. A second insertion plate 73 is movably inserted into the second insertion hole 75. An elastic block 74 is fixedly connected to the outer wall of one end of the second insertion plate 73. The outer wall of one end of the elastic block 74 is fixedly connected to the other side of the inner wall of the mounting groove 24. A second groove 7 is provided above the outer wall of the other end of the mounting bracket 3. A second shelf 77 is fixedly connected to the inner wall of the second groove 7. A second rotating rod 72 is rotatably connected to the lower part of the inner wall of the second groove 7. A second tightening rope 78 is wound around the outer wall of the second rotating rod 72. The outer wall of one end of the tightening rope 78 is fixedly connected to the outer wall of one side of the second insertion plate 73. A second turntable 71 is fixedly connected to the outer wall of the top of the second rotating rod 72. A second handle 76 is fixedly connected to the outer wall of the top of the turntable 71.
[0038] The left-right adjustment function of this invention can adapt to various installation scenarios. Regardless of whether the initial position of receiver 21 is biased to the left or right, it can be adjusted to a suitable position by rotating handle 2 76 and handle 1 57, which improves the versatility and adaptability of the device. Adjusting receiver 21 left and right can ensure that receiver 21 and transmitter 2 always remain parallel and aligned. When transmitter 2 sends a signal, receiver 21 can receive it accurately, reducing signal attenuation and interference, improving the efficiency and reliability of signal transmission, thereby ensuring that the curved elevator door can open and close the door in a timely and accurate manner according to the signal.
[0039] In Example 5, based on Example 1, an air pump 4 is fixedly connected to the lower part of the inner wall of the arc-shaped elevator body 1. A heating chamber 41 is fixedly connected to the output end of the air pump 4. A connecting pipe 42 is fixedly connected to the outer wall of one end of the heating chamber 41. A cavity 45 is opened in the lower part of the mounting bracket 3. The interior of the cavity 45 is fixedly connected to the outer wall of the connecting pipe 42. A flow channel 46 is opened in the upper part of the cavity 45. The outer wall of the flow channel 46 is connected to the interior of the slide groove 25. A strip groove 43 with two outer walls connected is opened on the receiver 21. A strip groove 44 with two outer walls connected is opened on the slide rod 26. A spiral frame 8 is fixedly connected to the inner wall of the heating chamber 41. A heating wire is provided inside the spiral frame 8.
[0040] The airflow can serve as a reminder to passengers, prompting them to quickly leave the curved elevator door. If light debris is blocking the closing of the curved elevator door, the airflow can deflect the debris, allowing the curved elevator door to close normally. The heating wires work to heat the interior of the heating chamber 41. The airflow absorbs heat as it passes through the heating chamber 41, and the air blown onto the passenger becomes slightly warm. This slightly warm airflow can effectively reduce the discomfort caused by cold air, making the passenger feel more comfortable when receiving reminders, preventing negative emotions caused by cold stimulation, and improving the overall user experience. By increasing the time the airflow stays inside the heating chamber 41, the heat generated by the heating wire inside the spiral frame 8 is absorbed more efficiently, the heating speed of the airflow is accelerated, the heating efficiency is improved, and the blown airflow reaches the ideal temperature, effectively preventing the airflow from flowing out before it is fully heated.
[0041] The working principle and usage process of this invention are as follows: First, the transmitter 2 is fixed to the top of the arc-shaped door elevator body 1 using screws. Then, the receiver 21 is inserted into the mounting slot 24. Next, the position of the slide rod 26 inside the slide groove 25 is adjusted so that the threaded hole on the slide rod 26 aligns with the threaded hole on the receiver 21. Finally, the receiver 21 and the slide rod 26 are connected together using a screw rod 23, thereby fixing the receiver 21 inside the mounting slot 24 and preventing the receiver 21 from falling out of the mounting slot 24 during operation of the arc-shaped door elevator body 1. If the receiver 21 moves away from the transmitter 2, it will affect the alignment between the receiver 21 and the transmitter 2. Accordingly, the receiver 21 can receive the signal in time when the transmitter 2 sends it. If the light is blocked, the elevator door will be triggered to reverse and open immediately to prevent passengers from being pinched. Since the receiver 21 and the transmitter 2 are set on the upper and lower sides of the elevator door according to the shape of the curved elevator door, the accuracy of the use of the transmitter 2 and the receiver 21 is effectively guaranteed, the error in the operation of the transmitter 2 and the receiver 21 is reduced, the timeliness and accuracy of signal transmission are guaranteed, and reliable signal support is provided for the normal operation of the curved elevator door.
[0042] When the receiver 21 is inserted into the mounting slot 24, the operator needs to manually align the first insertion plate 53 and the second insertion plate 73 at both ends of the mounting slot 24 with the first insertion hole 54 and the second insertion hole 75 at both ends of the receiver 21, so that the first insertion plate 53 and the second insertion plate 73 are inserted into the first insertion hole 54 and the second insertion hole 75 respectively. The first elastic block 52 and the second elastic block 74 are respectively provided on both sides of the first insertion plate 53 and the second insertion plate 73. The elastic force of the two is the same. When the first tightening rope 58 and the second tightening rope 78 are the same length, the receiver 21 is centered inside the mounting slot 24 under the action of the first elastic block 52 and the second elastic block 74. The operator does not need to perform additional complicated centering adjustment operations, which further simplifies the installation process and improves the convenience and accuracy of installation.
[0043] This invention allows the operator to push the insert rods 62 at both ends of the mounting frame 3, causing the insert rods 62 to separate from the first turntable 55 and the second turntable 71 respectively. This allows the second rotating rod 72 and the first rotating rod 56 to rotate. By setting the insert rods 62, when the two insert rods 62 are inserted into the first turntable 55 and the second turntable 71 respectively, the second rotating rod 72 and the first rotating rod 56 can be limited, preventing the second rotating rod 72 and the first rotating rod 56 from rotating. Correspondingly, the stability of the first rotating rod 56 and the second rotating rod 72 is increased, which further improves the stability of the receiver 21 inside the mounting frame 3 and prevents the first tightening rope 58 and the second tightening rope 78 from loosening and affecting the stability of the receiver 21.
[0044] After releasing the limiting positions of rotating rod 56 and rotating rod 72, the handle 57 is rotated. This rotation causes the turntable 55 to rotate, thus tightening the tightening rope 58. Simultaneously, rotating rod 72 relaxes the tightening rope 78, lengthening it and keeping both ropes 58 taut. This tension prevents the receiver 21 from shifting after being moved to the designated position. The tightening of rope 58 allows for slight adjustments within the mounting slot 24, ensuring the receiver 21 remains parallel and aligned with the transmitter 2. The tension of the ropes can be adjusted to suit different installation environments, compensating for minor errors during installation and ensuring the receiver 21 remains in the correct position.
[0045] This invention allows the turntable 71 to drive the rotating rod 72 to tighten the tightening rope 78 by rotating the handle 76. This tightening rope 78 then pulls the insert plate 73 to move. Due to the connection between the insert plate 73 and the insertion hole 75, when the insert plate 73 is pulled, it can move the receiver 21 to the other end inside the mounting slot 24. Through the action of the handle 76 and the handle 57, the receiver 21 can be adjusted left and right. The left and right adjustment function of this invention can adapt to various installation scenarios. No matter whether the receiver 21 is initially biased to the left or right, it can be adjusted to a suitable position by rotating the handle 76 and the handle 57, which improves the versatility and adaptability of the device. The left and right adjustment of the receiver 21 can ensure that the receiver 21 and the transmitter 2 always remain parallel and aligned. When the transmitter 2 sends a signal, the receiver 21 can receive it accurately, reducing signal attenuation and interference, improving the efficiency and reliability of signal transmission, and thus ensuring that the curved elevator door can open and close in a timely and accurate manner according to the signal.
[0046] The present invention connects the receiver 21 and the tightening rope 28 together by connecting the second insert plate 73 and the second socket 75. This allows the receiver 21 to move while the tightening rope 28 moves. At the same time, by connecting the second insert plate 73 and the second socket 75, the receiver 21 can be replaced or repaired simply by removing the screw rod 23 on the receiver 21 and pulling the receiver 21 out of the second insert plate 73.
[0047] When the signal transmitted from transmitter 2 to receiver 21 is blocked, the present invention transmits the detected signal to control box 22. Control box 22 immediately controls the arc-shaped elevator door to reverse and open, interrupting the closing action of the arc-shaped elevator door in time, preventing the arc-shaped elevator door from continuing to close and injuring passengers or objects, thus providing reliable safety for passengers and objects. At the same time, it controls the air pump 4 to move. The gas generated by the air pump 4 enters the cavity 45 through the heating chamber 41 and the connecting pipe 42, and then moves through the flow channel 46, thereby blowing upward through the strip groove 43. If a passenger obstructs the closing action of the arc-shaped elevator door, the airflow can serve as a reminder to the passenger, prompting the passenger to quickly leave the position of the arc-shaped elevator door. If a light object obstructs the closing action of the arc-shaped elevator door, the airflow will deflect the object, allowing the arc-shaped elevator door to close normally.
[0048] It should be noted that the air pump 4 can be frequently started when it is hot. The cold air blown out by the air pump 4 can drive the heat generated by the receiver 21 when it is working, further improving the heat dissipation of the receiver 21. The groove of the mounting slot 24 has a heat conduction function.
[0049] When the weather is cold, this invention uses an airflow to remind passengers to quickly leave the curved elevator door. The spiral frame 8, located within the heating chamber 41, contains heating wires. These wires heat the interior of the heating chamber 41, causing the airflow to absorb heat as it passes through. This results in the airflow becoming slightly warm when it reaches the passenger. This slightly warm airflow effectively reduces the discomfort caused by cold air, making the passenger feel more comfortable when receiving the reminder and preventing negative emotions caused by cold stimulation, thus improving the overall user experience.
[0050] This invention utilizes a spiral-shaped spiral frame 8, with its outer wall fixedly connected to the inner wall of the heating chamber 41. This ensures that the airflow entering the heating chamber 41 flows only along the spiral path of the spiral frame 8, making full contact with its outer wall. This increases the contact area between the airflow and the spiral frame 8, and extends the residence time of the airflow within the heating chamber 41. Consequently, it more efficiently absorbs the heat generated by the heating wire within the spiral frame 8, accelerates the heating rate of the airflow, improves heating efficiency, ensures that the blown airflow reaches the ideal temperature, and effectively prevents the airflow from flowing out before it is fully heated.
[0051] It should be noted that buffer pads are provided between receiver 21 and mounting bracket 3, between plug plate 1 53 and socket 1 54, and between socket 2 75 and plug plate 2 73.
