Description

Technical Field

[0001] This application relates to the field of control device technology, and in particular to an emergency opening control device for multi-terminal control boxes of elevators with permission linkage. Background Technology

[0002] Elevator multi-terminal control boxes refer to human-machine interaction terminals distributed in different locations within the elevator, used to realize functions such as floor selection, access control, and emergency operation. Their core value lies in covering the needs of users in all scenarios (such as ordinary passengers, emergency personnel, and accessible users), while ensuring safety, compliance, and efficient management. The core objective of the multi-terminal control box's access control linkage is safety priority. In emergencies (such as fire or earthquake), access to all floors is released within 30 seconds to ensure priority passage for fire / emergency services. The emergency activation control device is the "last line of defense" in the elevator safety system, a distributed system composed of hardware entities, software logic, and a communication network. Specifically, it can be divided into two categories: the first is a centralized controller, i.e., an embedded control box (such as a wall-mounted metal enclosure with IP65 protection), and a distributed control panel, i.e., a touch-screen LCD (integrated into the car control box / hall panel).

[0003] Regarding the aforementioned technologies, the inventors have discovered the following defects in this patent:

[0004] The installation of an embedded touch screen in an elevator car requires drilling holes at the four corners of the touch screen and corresponding holes in the elevator car for fixing with screws. This makes the installation process quite complicated, requiring precise alignment of the holes and moderate tightening of the screws to avoid damaging the touch screen or the surface of the car. Tools are also needed to assist in drilling and tightening the screws.

[0005] Therefore, in response to the above problems, the applicant provides an emergency opening control device for multi-terminal control boxes of elevators with linked permissions. Utility Model Content

[0006] To address the problems mentioned in the background art, this application provides an elevator multi-terminal control box permission linkage emergency opening control device, including a touch screen and an "L"-shaped slot. The touch screen is provided with a disassembly and assembly mechanism with a component positioning function. The disassembly and assembly mechanism includes a slot plate and a plug, and the plug is inserted into the slot plate.

[0007] The "L"-shaped groove is equipped with a hidden adsorption mechanism. The adsorption mechanism includes a linear module, an electric push rod, a suction fan mounting base, a suction fan, and a suction pipe. The sliding end of the linear module is horizontally mounted with the bottom end of the input end of the electric push rod. The output end of the electric push rod is fixedly connected to the suction fan mounting base. The suction fan is mounted on the suction fan mounting base, and the air inlet end of the suction fan is fixedly connected to the suction pipe.

[0008] Optionally, the elevator car has a cover plate groove on the right side of the car door, the cover plate groove is connected to a partition, the cover plate groove and the touch screen groove are fixedly connected by a partition, and the elevator car has an "L" shaped groove below the touch screen groove.

[0009] Optionally, a cover plate is hinged to the top of the cover plate groove, and a touch screen is held in the touch screen groove, with the top surface of the touch screen contacting the bottom surface of the partition.

[0010] Optionally, slot plates are fixedly connected to the top and bottom of both sides of the touch screen, with the two top slot plates located in the cover plate groove and the two bottom slot plates located in the touch screen groove.

[0011] Optionally, the installation assembly consists of a handle, inserts, and magnets. The handle is vertically fixed to both ends with inserts, and magnets are embedded and fixed to the bottom of the inserts. Iron blocks are embedded and fixed to the bottom of the grooves on both sides of the partition.

[0012] Optionally, the two pins are vertically inserted into the slot and slot plate respectively, and the magnet magnetically attracts the iron block.

[0013] Optionally, a linear module is vertically installed on the "L"-shaped groove, a dust collection tank is threadedly connected to the air outlet of the suction fan, multiple suction heads are installed on the suction pipe, and the linear module, electric push rod and suction fan are electrically connected to a controller.

[0014] This application provides an elevator multi-terminal control box access linkage emergency opening control device, which adopts the following technical solution:

[0015] In summary, this application includes the following beneficial technical effects:

[0016] 1. This utility model achieves the advantage of rapid installation of the touch screen by first inserting the touch screen into the touch screen slot, then inserting the pins downwards with the two top slot plates aligned with them. As the installation component descends under the weight of the component, it passes through the slot and the two bottom slot plates in sequence, while the magnet attracts the iron block. This avoids the troublesome and cumbersome steps of positioning the touch screen with auxiliary tools, which is required for embedded installation. At the same time, the touch screen is easy to disassemble quickly, making it convenient for inspection and replacement.

[0017] 2. This utility model uses a controller to control an electric push rod to push the suction fan mounting base, suction fan, dust collection tank, suction pipe, and suction head out of the "L"-shaped groove. Then, the sliding end of the linear module drives the electric push rod, suction fan mounting base, suction fan, dust collection tank, suction pipe, and suction head to slide from bottom to top. This allows the suction fan to be hidden and stored after adsorbing dust on the touch screen surface, thus avoiding the problem of the adsorption mechanism occupying too much space in the elevator car.

[0024] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0025] This application discloses an emergency opening control device for multi-terminal control boxes of elevators with permission linkage.

[0026] like Figure 1-5 As shown, an elevator multi-terminal control box permission linkage emergency opening control device includes a touch screen 3 and an "L"-shaped slot 104. The touch screen 3 is provided with a disassembly and assembly mechanism with a positioning function for the installation component 5. The disassembly and assembly mechanism includes a slot plate 4 and a plug 51. The plug 51 is inserted into the slot plate 4.

[0027] The L-shaped groove 104 is equipped with a hidden adsorption mechanism. The adsorption mechanism includes a linear module 7, an electric push rod 8, a suction fan mounting base 9, a suction fan 10, and a suction pipe 12. The sliding end of the linear module 7 is horizontally mounted with the bottom end of the input end of the electric push rod 8. The output end of the electric push rod 8 is fixedly connected to the suction fan mounting base 9. The suction fan 10 is mounted on the suction fan mounting base 9. The air inlet end of the suction fan 10 is fixedly connected to the suction pipe 12.

[0028] Please see Figure 2The elevator car 1 has a cover plate groove 100 on the right side of the car door. The cover plate groove 100 is connected to partitions 102 and 103. The partition 102 is fixedly connected between the cover plate groove 100 and the touch screen groove 101. The elevator car 1 has an "L"-shaped groove 104 below the touch screen groove 101. An alarm is installed on the touch screen 3 to remind people who are close to the touch screen 3 to keep their distance. This is to avoid the linear module 7 driving the suction fan mounting base 9, the suction fan 10, and the dust collection tank 1. 1. If the suction pipe 12 and the suction head 13 touch the user during their up-and-down movement, causing injury, the suction fan 10, dust collection tank 11, suction pipe 12 and suction head 13 are all equipped with sensors. When a person comes into contact with the above structure, the system will immediately enter an emergency stop state. The "L"-shaped groove 104 is designed to hide the unused suction fan mounting base 9, suction fan 10, dust collection tank 11, suction pipe 12 and suction head 13 in the "L"-shaped groove 104 by extending and retracting the electric push rod 8.

[0029] Please see Figure 1 A cover plate 2 is hinged to the top of the cover plate groove 100, and a touch screen 3 is held in the touch screen groove 101. The top surface of the touch screen 3 is in contact with the bottom surface of the partition 102.

[0030] Please see Figure 1 The top and bottom sides of the touch screen 3 are fixedly connected with slot plates 4. The two top slot plates 4 are located in the cover plate groove 100, and the two bottom slot plates 4 are located in the touch screen groove 101. The touch screen 3 is the car control box area. The 15.6-inch to 21.5-inch embedded touch screen (IP65 protection) realizes the functions of floor selection, permission verification, emergency operation and multimedia information display.

[0031] Please see Figure 3 The installation assembly 5 consists of a handle 50, a post 51, and a magnet 52. The handle 50 is vertically fixed to both ends with the post 51, and the post 51 is embedded and fixed to the bottom of the post 51. Iron blocks 6 are embedded and fixed to the bottom of the grooves on both sides of the partition 102.

[0032] Please see Figure 3 The two insertion posts 51 are vertically inserted into the slot 103 and the slot plate 4, respectively, and the magnet 52 magnetically attracts the iron block 6.

[0033] Please see Figure 4A linear module 7 is vertically installed on the "L"-shaped groove 104. A dust collection tank 11 is threadedly connected to the air outlet of the suction fan 10. Multiple suction heads 13 are installed on the suction pipe 12. The linear module 7, the electric push rod 8, and the suction fan 10 are electrically connected to a controller. The surface of the dust collection tank 11 is evenly arranged with cross-grids. The grids are regular square or rhomboid structures. The grid aperture is determined according to the particle size distribution of the dust to be intercepted. For example, if the main target is dust particles with a diameter greater than 10 micrometers, the grid aperture can be designed to be 5 micrometers to 8 micrometers to ensure effective dust interception while allowing air to pass through smoothly.

[0034] The implementation principle of the elevator multi-terminal control box access linkage emergency opening control device in this application embodiment is as follows:

[0035] The installation steps for Touchscreen 3 are as follows:

[0036] First, insert the touch screen 3 into the touch screen slot 101, then flip the cover plate 2 upwards, hold the handle 50 and fit it into the cover plate slot 100, and insert the pin 51 downwards with the two top slot plates 4 aligned with the handle 50. As the installation component 5 descends due to gravity, it passes through the slot 103 and the two bottom slot plates 4 in sequence. At the same time, the magnet 52 is attracted to the iron block 6, which locks the position of the installation component 5 to prevent it from jumping up and down with the vibration of the elevator car 1. Meanwhile, the pin 51 can position the slot plate 4 and the touch screen 3, thus achieving the advantage of quick installation of the touch screen 3.

[0037] The controller controls the intermittent operation of the linear module 7, the electric push rod 8, and the suction fan 10 to clean the dust from the touch screen 3. The cleaning process is as follows:

[0038] The controller controls the output end of the electric push rod 8 to drive the suction fan mounting base 9, suction fan 10, dust collection tank 11, suction pipe 12 and suction head 13 out of the "L" shaped groove 104. Then, the sliding end of the linear module 7 drives the electric push rod 8, suction fan mounting base 9, suction fan 10, dust collection tank 11, suction pipe 12 and suction head 13 to slide from bottom to top. At the same time, the suction fan 10 is turned on, so that the dust on the surface of the touch screen 3 flows through the suction head 13 into the suction pipe 12 and is finally discharged from the dust collection tank 11.

[0039] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
