Description

Technical Field

[0001] This utility model relates to the field of two-way self-locking hall door technology, and in particular to a two-way self-locking hall door electromagnetic locking mechanism. Background Technology

[0002] The elevator hall door frame is mainly composed of the top sill, columns, and bottom sill. The top sill is located at the top of the hall door and is an important supporting component of the hall door frame. It serves to fix the door leaf, install the door operator system and related door lock devices, and guide the vertical movement of the door leaf. The columns are installed vertically on both sides of the hall door. They mainly support the top sill and bottom sill, as well as fix the door leaf, ensuring the stability of the overall structure of the hall door, and also play a certain decorative role.

[0003] Chinese Patent CN220449483U discloses an electromagnetic locking device for the hall door of a household ladder, which solves the problems of complex mechanical lock structure, electronic locks requiring power to unlock, and rigid opening methods. The device includes an electrical switch and an electrical contact plate installed on the hall door and moving synchronously with it, an electromagnetic lock fixedly installed on the upper plate of the hall door, and a reset mechanism. Below the electrical switch is a lock hook plate with several lock hook holes. Below the electromagnet inside the electromagnetic lock is a movable rod, and below the movable rod is a lock tongue. When the hall door is in position, the electromagnetic lock is de-energized, and the spring force causes the lock tongue to fall through the lock hook holes, connecting the electrical contact plate and the electrical switch, locking the hall door. Before the hall door is opened, the electromagnetic lock is energized, the lock tongue disengages, and the hall door opens. This solution does not have a complex unlocking system, has a simple mechanical structure, and offers flexible opening methods.

[0004] The electromagnetic locking device for the hall door of the aforementioned household ladder has some problems in use. Although the mechanical structure is simple and the door opening method is flexible, and the lock tongue can prevent the hall door from being easily opened by inserting into the lock hook hole, the structure of the lock hook plate and the lock tongue is relatively simple and cannot withstand large external impacts. Utility Model Content

[0005] This utility model aims to address the shortcomings of existing technologies by providing a two-way self-locking electromagnetic locking mechanism for hall doors.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a two-way self-locking electromagnetic locking mechanism for hall doors, including an upper sill. A mounting plate is connected to the bottom center of the upper sill via a detachable fixing component. An I-shaped hole is formed in the middle of the mounting plate. An I-shaped plate is slidably connected to the inner cavity of the I-shaped hole. Two sets of hall doors are slidably connected to the lower part of the upper sill. A T-shaped groove is formed on the upper part of the corresponding side of each of the two sets of hall doors. The inner cavities on both sides of the I-shaped hole are provided with downward-pushing corresponding side I-shaped grooves. The end of the I-shaped plate is engaged with the elastic pusher in the inner cavity of the corresponding T-shaped groove. The top of both sets of elastic pushers is fixedly connected with a 7-shaped plate. The top of both sets of hall doors and the corresponding position of the 7-shaped plate are provided with slots for inserting the 7-shaped plate. When the elastic pusher pushes the I-shaped plate downward, it also drives the 7-shaped plate downward through the mounting plate and inserts it into the inner cavity of the corresponding slot. A puller is provided above the mounting plate for pulling the I-shaped plate upward to release the restriction on the hall door.

[0007] Furthermore, the pulling component includes a mounting bracket fixedly installed on the top of the mounting plate, an electromagnetic lock fixedly installed on the top of the mounting bracket, the input end of the electromagnetic lock being electrically connected to the elevator control system via a wire, and the actuating end of the electromagnetic lock penetrating downward through the mounting bracket and connected to the I-shaped plate via an adjusting component.

[0008] Furthermore, the elastic pusher includes mounting strips fixedly installed on the top of both sides of the mounting plate. The bottom of each set of mounting strips is provided with a spring. The bottom of each set of springs respectively contacts the top of the corresponding side I-shaped plate. The bottom of each set of mounting strips is provided with an adjusting member for adjusting the spring force of the corresponding side spring.

[0009] Furthermore, the adjusting component includes a screw inserted into the center of the top of each set of mounting strips, the bottom of the two sets of screws being fixedly connected to the top of the corresponding side of the I-shaped plate, the upper surface of the two sets of screws being threaded with connecting nuts, the bottom of the two sets of connecting nuts contacting the top of the corresponding side mounting strip, and the upper surface of the two sets of L-shaped plates being connected to the top of the corresponding side screws.

[0010] Furthermore, the detachable fastener includes a square hole formed on the bottom surface of the upper sill and adapted to the mounting plate. The two ends of the mounting plate are respectively fixedly connected to a fixing ring. When the mounting plate is engaged in the inner cavity of the square hole, the two sets of fixing rings are respectively engaged in the bottom of the mounting plate. The inner cavities of the two sets of fixing rings are each inserted with a fixing bolt. The two sets of fixing bolts are respectively threaded to the corresponding bottom surface of the mounting plate.

[0011] Furthermore, the adjusting component includes a connecting tube fixedly installed on the top of the I-shaped plate, the actuating end of the electromagnetic lock extending into the inner cavity of the connecting tube, and two sets of surfaces of the connecting tube having strip-shaped holes arranged along the height. Threaded rods are inserted into the inner cavities of the two sets of strip-shaped holes, and the ends of the two sets of threaded rods are respectively fixedly connected to the corresponding side surfaces of the actuating end of the electromagnetic lock. Limiting nuts are threadedly connected to the ends of the two sets of threaded rods, and the surfaces of the two sets of limiting nuts respectively contact the corresponding side surfaces of the connecting tube.

[0012] The beneficial effects of this utility model are:

[0013] 1. This utility model, through the setting of the I-shaped plate and the L-shaped plate, allows the I-shaped plate to withstand the impact force when the hall door is closed and various external forces in the locked state when the elastic pusher pushes the I-shaped plate downward into the T-shaped groove, thus ensuring the reliability of the entire hall door locking system. Furthermore, under the action of the elastic pusher, the L-shaped plate moves downward together with the I-shaped plate, and its end is inserted into the slot at the top of the hall door, further enhancing the locking effect of the hall door. At the same time, it cooperates with the I-shaped plate to restrict the hall door from different directions, making the hall door more stable in the closed state and preventing the hall door from shaking or shifting.

[0014] 2. By incorporating an elastic pusher, this invention releases the restriction on the I-shaped plate when the electromagnetic lock is de-energized. Furthermore, the spring ensures that the I-shaped plate maintains a downward pushing force even when not subjected to external force, thus ensuring stable locking of the hall door when closed. This improves the reliability of the system and eliminates the need for prolonged energization of the electromagnetic lock, effectively preventing overheating and extending its service life.

[0015] 3. With the detachable fastener, this utility model allows for easy installation by simply inserting the mounting plate into the square hole and tightening the fixing bolts. During disassembly, the mounting plate can be easily removed by unscrewing the fixing bolts, facilitating the repair, replacement, or adjustment of the mounting plate and its components, thus reducing maintenance costs and difficulties.

[0025] The following will describe in detail the embodiments of this utility model with reference to the accompanying drawings. Detailed Implementation

[0026] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0027] like Figures 1-4As shown, the bidirectional self-locking electromagnetic locking mechanism for hall doors includes an upper sill 100. A mounting plate 203 is detachably fixed to the bottom center of the upper sill 100 via a fastener. An I-shaped hole 206 is formed in the middle of the mounting plate 203. An I-shaped plate 204 is slidably connected to the inner cavity of the I-shaped hole 206. Two sets of hall doors 101 are slidably connected to the lower part of the upper sill 100. T-shaped grooves 103 are formed on the upper part of the corresponding sides of the two sets of hall doors 101. The I-shaped hole 206... Both the left and right inner cavities are equipped with elastic pushers that push the ends of the corresponding I-shaped plates 204 downwards to engage with the inner cavities of the corresponding T-shaped grooves 103. A 7-shaped plate 205 is fixedly connected to the top of each of the two sets of elastic pushers. Slots 104 for inserting the 7-shaped plates 205 are provided at the top of both sets of hall doors 101 and at positions corresponding to the 7-shaped plates 205. When the elastic pushers push the I-shaped plates 204 downwards, they also drive the 7-shaped plates 205 downwards through the wall. The mounting plate 203 is inserted into the inner cavity of the corresponding side slot 104. A pulling member is provided above the mounting plate 203 for pulling the I-shaped plate 204 upward to release the restriction on the hall door 101. With the setting of the I-shaped plate 204 and the L-shaped plate 205, when the elastic pusher pushes the I-shaped plate 204 downward into the T-shaped groove 103, the I-shaped plate 204 can withstand the impact force when the hall door 101 is closed and various external forces in the locked state, ensuring the reliability of the entire hall door 101 locking system. Furthermore, under the action of the elastic pusher, the L-shaped plate 205 moves downward with the I-shaped plate 204, and its end is inserted into the slot 104 at the top of the hall door 101, further enhancing the locking effect of the hall door 101. At the same time, it cooperates with the I-shaped plate 204 to restrict the hall door 101 from different directions, making the hall door 101 more stable in the closed state and preventing the hall door 101 from shaking or shifting.

[0028] The pulling component includes a mounting bracket 207 fixedly installed on the top of the mounting plate 203. An electromagnetic lock 200 is fixedly installed on the top of the mounting bracket 207. The input end of the electromagnetic lock 200 is electrically connected to the elevator control system through a wire. The actuating end of the electromagnetic lock 200 passes downward through the mounting bracket 207 and is connected to the I-shaped plate 204 through an adjusting component. Through the setting of the pulling component, automatic control can be realized. When the elevator control system sends a corresponding signal, the electromagnetic lock 200 can accurately actuate, pull the I-shaped plate 204 upward, release the restriction on the hall door 101, realize the automatic opening of the hall door 101, and improve the automation level and safety of elevator operation.

[0029] Elevator control systems are well-known technologies to those skilled in the art. The principle of how the electromagnetic lock 200 is controlled is summarized as follows: an infrared sensing device with a light curtain installed between the car door and the landing door 101 detects whether there are obstacles in the door area by emitting and receiving infrared rays. When the landing door 101 is closed, if no obstacle is detected in the light curtain, it means that the landing door 101 has been closed normally. The safety contact plate is an elastic device installed on the edge of the car door. When the landing door 101 touches an obstacle during the closing process, the safety contact plate will be squeezed and deformed.

[0030] The signals detected by the light curtain or safety touch panel are transmitted to the elevator door control system. If the light curtain does not detect an obstacle or the safety touch panel is not triggered, the door control system will consider the hall door 101 to be closed normally and transmit the relevant signals to the elevator control system, thereby controlling the electromagnetic lock 200.

[0031] Electromagnetic lock 200 is a well-known technical means in the art. For its specific working principle and structure, please refer to the electromagnetic lock 200 in the electromagnetic locking device for the hall door of a household ladder in the publication number CN220449483U. Other details will not be repeated here.

[0032] The elastic pusher includes mounting strips 300 fixedly installed on the top of both sides of the mounting plate 203. A spring 301 is provided at the bottom of each of the two sets of mounting strips 300. The bottom of each set of springs 301 contacts the top of the corresponding side I-shaped plate 204. Each set of mounting strips 300 has an adjusting component at its bottom for adjusting the elastic force of the corresponding side spring 301. Through the setting of the elastic pusher, when the electromagnetic lock 200 is de-energized, the restriction on the I-shaped plate 204 is released. Furthermore, the setting of the springs 301 ensures that the I-shaped plate 204 can always maintain a downward pushing force when not subjected to external force, thus ensuring that the hall door 101 remains stably locked in the closed state, improving the reliability of the system. Moreover, it eliminates the need for prolonged power supply to the electromagnetic lock 200, effectively preventing the electromagnetic lock 200 from overheating and thus extending its service life.

[0033] The adjusting component includes a screw 303 inserted into the center of the top of each set of mounting strips 300. The bottoms of the two sets of screws 303 are respectively fixedly connected to the top of the corresponding side of the I-shaped plate 204. The upper surfaces of the two sets of screws 303 are threaded with connecting nuts 302. The bottoms of the two sets of connecting nuts 302 contact the top of the corresponding side mounting strip 300. The upper surfaces of the two sets of L-shaped plates 205 are respectively connected to the top of the corresponding side screws 303. With the setting of the adjusting component, the degree of compression or tension of the spring 301 can be changed by simply rotating the connecting nuts 302, thereby adjusting the elastic force. No complicated tools or disassembly operations are required. This not only realizes the adjustable function of the elastic force of the spring 301, but also ensures that the structure of the entire device is compact and does not occupy too much space. It is conducive to achieving efficient functional integration within the limited installation space of the elevator hall door 101.

[0034] The detachable fastener includes a square hole 102 on the bottom surface of the upper sill 100 that is adapted to the mounting plate 203. Fixing rings 201 are fixedly connected to both ends of the mounting plate 203. When the mounting plate 203 is engaged with the inner cavity of the square hole 102, the two sets of fixing rings 201 are engaged with the bottom of the mounting plate 203. Fixing bolts 202 are inserted into the inner cavities of both sets of fixing rings 201. The two sets of fixing bolts 202 are threaded onto the corresponding bottom surfaces of the mounting plate 203. With the detachable fastener, during installation, simply engage the mounting plate 203 with the square hole 102 and tighten the fixing bolts 202. During disassembly, unscrewing the fixing bolts 202 allows for easy removal of the mounting plate 203, facilitating maintenance, replacement, or adjustment of the mounting plate 203 and its components, thus reducing maintenance costs and difficulty.

[0035] The adjusting component includes a connecting pipe 400 fixedly installed on the top of the I-shaped plate 204. The actuating end of the electromagnetic lock 200 extends into the inner cavity of the connecting pipe 400. Both sets of surfaces of the connecting pipe 400 are provided with strip-shaped holes 402 arranged along the height. Threaded rods 401 are inserted into the inner cavities of both sets of strip-shaped holes 402. The ends of the two sets of threaded rods 401 are respectively fixedly connected to the corresponding side surfaces of the actuating end of the electromagnetic lock 200. Limiting nuts 403 are threadedly connected to the ends of the two sets of threaded rods 401. The surfaces of the two sets of limiting nuts 403 respectively contact the corresponding side surfaces of the connecting pipe 400. Through the setting of the adjusting component, the connection height between the actuating end of the electromagnetic lock 200 and the I-shaped plate 204 can be adjusted. According to different installation positions and actual needs, the relative position of the electromagnetic lock 200 and the I-shaped plate 204 can be precisely adjusted to ensure that the electromagnetic lock 200 can effectively pull the I-shaped plate 204, realizing the normal opening and closing of the hall door 101.

[0036] Working principle;

[0037] When the elevator control system sends a door closing signal, the two sets of hall doors 101 slide to the middle and close. When the two sets of hall doors 101 are closed, the elevator control system sends a signal to the electromagnetic lock 200 and cuts off the power to the electromagnetic lock 200. As a result, the two ends of the I-shaped plate 204 are respectively engaged in the inner cavity of the corresponding side T-shaped groove under the push of the two sets of springs 301, thereby achieving the initial mechanical locking of the hall door 101.

[0038] At the same time, when the spring 301 pushes the I-shaped plate 204 downward, the screw 303 moves downward together, thereby driving the 7-shaped plate 205 to pass through the mounting plate 203 and be inserted into the inner cavity of the corresponding slot 104 at the top of the hall door 101, further strengthening the locking of the hall door 101;

[0039] When the elevator control system sends an opening signal, the electromagnetic lock 200 receives the signal and its actuating end pulls the I-shaped plate 204 upward. The I-shaped plate 204 moves upward, overcoming the elastic force of the spring 301, so that the end of the I-shaped plate 204 disengages from the inner cavity of the T-shaped groove 103 of the hall door 101. At the same time, it drives the 7-shaped plate 205 to move upward, so that it disengages from the inner cavity of the slot 104 of the hall door 101, releasing the restriction on the hall door 101. Then, the elevator door operator system drives the hall door 101 to slide open to both sides.

[0040] Meanwhile, depending on the actual use, if it is necessary to adjust the elastic force of spring 301, it can be achieved by rotating the connecting nut 302. Rotating the connecting nut 302 upward increases the distance between it and the top of the mounting strip 300, stretching spring 301 and increasing elastic force; rotating the connecting nut 302 downward decreases the distance between it and the top of the mounting strip 300, compressing spring 301 and decreasing elastic force.

[0041] The present invention has been described above with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any improvements made using the inventive concept and technical solution of the present invention, or direct application to other situations without modification, are all within the protection scope of the present invention.
