Abstract
Description
Technical Field
[0001] This utility model relates to the field of machine tool processing technology, specifically to an electronic locking valve with graded anti-theft function. Background Technology
[0002] In modern industrial and civil applications, electronic shut-off valves, as key components for controlling the flow of media in pipeline systems, are widely used in scenarios such as tap water supply, gas transmission, heating systems, and industrial fluid control.
[0003] Traditional locking valves often use simple lock cylinders, key structures, or single snap-locking mechanisms. These structures are easily damaged by force, such as by prying bars or drilling, and cannot resist malicious intrusion. Furthermore, mechanical parts are prone to wear and tear after long-term use, leading to a decrease in the reliability of anti-theft measures. Utility Model Content
[0004] (a) Technical problems to be solved
[0005] To address the shortcomings of existing technologies, this utility model provides an electronic locking valve with graded anti-theft function, which solves the problems of easy mechanical damage, single electronic authentication, and non-compact structure making it difficult to maintain in traditional electronic locking valves.
[0006] (II) Technical Solution
[0007] To achieve the above objectives, this utility model provides the following technical solution: an electronic locking valve with tiered anti-theft function, comprising: a pipe, a valve handle, the valve handle being rotatably connected to the inner wall of the pipe, and an anti-theft device being fixedly connected to the outer wall of the pipe. The anti-theft device locks by sliding, and includes a limiting shell. A column is slidably connected to the inner wall of the limiting shell, and the outer wall of the column is arranged in a circumferential array along the central axis of the limiting shell. The anti-theft device uses a sliding locking method. The columns arranged in a circumferential array on the inner wall of the limiting shell slide in conjunction with the groove on the inner wall of the valve handle. When the column slides into the groove, it can mechanically limit the valve handle, preventing it from rotating arbitrarily, effectively preventing unauthorized personnel from opening or closing the valve by rotating the valve handle, thus achieving basic-level physical anti-theft.
[0008] Preferably, the inner wall of the limiting shell is fixedly connected to the outer wall of the pipe, and the outer wall of the column is slidably connected to the inner wall of the valve handle through a sliding groove, wherein the sliding groove is formed in the wall of the valve handle.
[0009] Preferably, a linkage plate is fixedly connected to the bottom end of the column, and a one-way screw is threadedly connected to the inner wall of the linkage plate. When the one-way screw rotates, it can drive the linkage plate to slide along the inner wall of the limiting shell, thereby synchronously driving multiple columns to slide up and down to achieve a unified locking or unlocking action.
[0010] Preferably, the outer wall of the linkage plate is slidably connected to the inner wall of the limiting shell, and the outer wall of the one-way screw is rotatably connected to the inner wall of the limiting shell.
[0011] Preferably, the top of the unidirectional screw is rotatably connected to a receiver housing, and the receiver housing contains an NFC receiver. The receiver housing at the top of the unidirectional screw contains an NFC receiver, which is used for identity authentication and unlocking control through NFC technology. Users only need to bring the authorized NFC device close to the receiver housing to quickly complete identity authentication, thereby driving the unidirectional screw to rotate and unlock. There is no need for complicated key or password operations, which improves the convenience of operation.
[0012] Beneficial effects
[0013] This utility model provides an electronic locking valve with a graded anti-theft function. It has the following beneficial effects:
[0014] This utility model incorporates an anti-theft device that uses a sliding lock mechanism. When the column slides into the groove, it mechanically limits the valve handle, preventing it from turning arbitrarily. This effectively prevents unauthorized personnel from opening or closing the valve by turning the valve handle, achieving basic-level physical anti-theft. When the one-way screw rotates, it drives the linkage plate to slide along the inner wall of the limiting shell, thereby synchronously driving multiple columns to slide up and down, achieving unified locking or unlocking actions. The receiver housing at the top of the one-way screw contains an NFC receiver, which uses NFC technology for identity authentication and unlocking control, enabling one electronic key per community and one key with one password, effectively improving the level of anti-theft heating management in heating supply management.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] Example
[0021] Please see Figure 1-3 This utility model provides a technical solution: an electronic locking valve with graded anti-theft function, comprising:
[0022] Pipe 1, valve handle 2, valve handle 2 is rotatably connected to the inner wall of pipe 1, and anti-theft device 3 is fixedly connected to the outer wall of pipe 1. Anti-theft device 3 is locked by sliding, and valve handle 2 is locked by anti-theft device 3, thereby realizing a key lock.
[0023] The anti-theft device 3 includes a limiting shell 30, with a column 31 slidably connected to the inner wall of the limiting shell 30. The outer wall of the column 31 is arranged in a circumferential array along the central axis of the limiting shell 30. The inner wall of the limiting shell 30 is fixedly connected to the outer wall of the pipe 1. The outer wall of the column 31 is slidably connected to the inner wall of the valve handle 2 through a sliding groove. The sliding groove is opened in the wall of the valve handle 2. When no unlocking operation is performed, the anti-theft device 3 is in a locked state. The column 31 arranged in a circumferential array on the inner wall of the limiting shell 30 is embedded in the sliding groove on the inner wall of the valve handle 2, forming a mechanical limit on the column 31, preventing the valve handle 2 from rotating, thereby restricting the flow of medium in the pipe 1. At this time, the valve is in a closed or locked state, and unauthorized personnel cannot easily open the valve.
[0024] A linkage plate 32 is fixedly connected to the bottom end of the column 31. A one-way screw 33 is threadedly connected to the inner wall of the linkage plate 32. The outer wall of the linkage plate 32 is slidably connected to the inner wall of the limiting shell 30. The outer wall of the one-way screw 33 is rotatably connected to the inner wall of the limiting shell 30. As the linkage plate 32 slides upward, it drives the multiple columns 31 fixedly connected to it to slide upward synchronously, so that the columns 31 gradually disengage from the grooves on the inner wall of the valve handle 2, releasing the mechanical limitation on the valve handle 2. At this time, the valve handle 2 can rotate freely, and the unlocking process is completed.
[0025] The top of the unidirectional screw 33 is rotatably connected to the receiver housing 34, and the receiver housing 34 contains an NFC receiver. When a user brings an authorized NFC device close to the receiver housing 34, the NFC receiver inside the receiver housing 34 receives the signal and authenticates the NFC device. Since NFC communication uses encryption technology, only devices that have been authenticated can continue subsequent operations. After authentication, the NFC receiver transmits the signal to the control module inside the receiver housing, and the control module drives the unidirectional screw 33 to rotate in a specific direction.
[0026] When in use, the valve handle 2 is locked by the anti-theft device 3, thereby achieving a key lock;
[0027] First, when no unlocking operation is performed, the anti-theft device 3 is in a locked state. The columns 31 arranged in a circular array on the inner wall of the limiting shell 30 are embedded in the sliding groove on the inner wall of the valve handle 2, forming a mechanical limit on the columns 31, preventing the valve handle 2 from rotating, thereby restricting the flow of medium in the pipeline 1. At this time, the valve is in a closed or locked state, and unauthorized personnel cannot easily open the valve.
[0028] When a user brings an authorized NFC device close to the receiver housing 34, the NFC receiver inside the receiver housing 34 receives the signal and authenticates the NFC device. Since NFC communication uses encryption technology, only devices that have been authenticated can continue subsequent operations. After authentication, the NFC receiver transmits the signal to the control module inside the receiver housing, and the control module drives the unidirectional screw 33 to rotate in a specific direction.
[0029] Since the one-way screw 33 is threadedly connected to the linkage plate 32, and the outer wall of the linkage plate 32 is slidably connected to the inner wall of the limiting shell 30, when the one-way screw 33 rotates, the linkage plate 32 is constrained by the threaded transmission and the inner wall of the limiting shell 30, and slides upward along the inner wall of the limiting shell 30.
[0030] As the linkage plate 32 slides upward, it drives the multiple columns 31 fixedly connected to it to slide upward synchronously, so that the columns 31 gradually disengage from the grooves on the inner wall of the valve handle 2, releasing the mechanical limit on the valve handle 2. At this time, the valve handle 2 can rotate freely, and the unlocking process is completed.
[0031] Once column 31 is unlocked, the user can turn valve handle 2 to rotate it on the inner wall of pipe 1, thereby opening or closing the valve and controlling the flow of medium in pipe 1.
