A tamper-proof electronic fence installation mechanism

Abstract

This utility model discloses an anti-tamper electronic fence installation mechanism, including a fence body assembly and an installation assembly. The fence body assembly includes two housings, with several grooves formed on the inner sidewalls of the housings. A slider is slidably connected to the inner sidewall of each groove, and a spring is installed on one side of each slider. The end of the spring away from the slider is fixedly connected to the inner sidewall of the groove. A connecting block is installed on one side of the slider. Through the setting of contact point one and contact point two, the connecting block and the slider are pre-compressed by the spring, so that the rectangular limiting block forms a dynamic lock after being inserted into the rectangular hole one. At the same time, contact point one and contact point two remain separated under the tension of the barbed wire. When the barbed wire is cut by external force, contact point one and contact point two will contact and close under the action of the spring, thereby triggering an alarm. Simultaneously, an attempt to pull the barbed wire will immediately force the slider to compress the spring, causing contact point three and contact point four to close, instantly triggering an alarm.

Description

Technical Field

[0001] This utility model specifically relates to an anti-disassembly electronic fence installation mechanism, belonging to the field of electronic fence technology. Background Technology

[0002] Electronic fences, as an important perimeter security system, are widely used in military facilities, prisons, airports, industrial parks, residential communities, and other locations with high security requirements. Their core function is to create a physical barrier, while also providing intrusion detection and real-time alarm capabilities. However, in practical applications, traditional electronic fence systems face a significant challenge: insufficient anti-tampering capabilities. Existing electronic fence installation structures typically rely on simple bolt fastening, snap-fit ​​connections, or direct burial. Intruders or vandals can easily use conventional tools (such as wrenches, pliers, and crowbars) to remove the fixing bolts, break the snap-fit, or directly pull away the barbed wire / wires, thereby compromising the fence's integrity and creating opportunities for illegal intrusion or equipment theft. When traditional mechanical connections are compromised, they often lack effective and immediate electronic monitoring methods. The system may only trigger an alarm when the fence wire is cut or short-circuited, while reacting slowly or failing to detect disassembly of the connecting mechanism itself, leading to security vulnerabilities. Some complex installation structures designed to improve security can make on-site installation, debugging, and maintenance cumbersome, affecting efficiency; while overly simple structures are insufficient to meet high-level anti-tampering requirements. Against this background, this utility model proposes an anti-disassembly electronic fence installation mechanism. Utility Model Content

[0003] The purpose of this utility model is to address the shortcomings of existing technologies by providing an anti-dismantling electronic fence installation mechanism, so as to achieve the purpose of preventing dismantling and facilitating installation.

[0004] A tamper-proof electronic fence installation mechanism includes a fence body assembly and an installation assembly;

[0005] The fence body assembly includes two housings. The inner walls of each housing have several grooves. A slider is slidably connected to the inner wall of each groove. A spring is installed on one side of each slider. The end of the spring away from the slider is fixedly connected to the inner wall of the groove. A connecting block is installed on one side of the slider. The connecting block has a rectangular hole and a rectangular groove. A second contact is installed on the inner wall of the groove. A first contact is installed on the side of the slider away from the spring. The dimensions of the first and second contacts are the same. A plate is installed at the bottom of the connecting block. A third contact is installed on one side of the first plate. Several second plates are installed on the inner wall of the housing. A fourth contact is installed on one side of the second plate. The dimensions of the fourth contact are the same as those of the third contacts. An mounting block is installed at the top of the connecting block. The mounting block has a threaded hole.

[0006] Furthermore, the outer wall of the shell is provided with several circular holes and several rectangular holes.

[0007] Furthermore, the installation assembly includes a rod and a plurality of barbed wires, with a handle 1 installed at each end of the barbed wires. A rectangular limiting block is installed at the end of the handle 1 away from the barbed wires. The length of the handle 1 is greater than the distance between the plate 2 and the nearest rectangular hole 2.

[0008] Furthermore, the dimensions of the rectangular limiting block are consistent with the dimensions of the first rectangular hole, the rectangular groove, and the second rectangular hole.

[0009] Furthermore, the outer wall of the rod is provided with external threads, and a handle is installed at one end of the rod.

[0010] Furthermore, the size of the external thread is the same as the size of the threaded hole, and the size of the circular hole is larger than the size of the rod body.

[0011] Furthermore, a connecting plate is installed at the bottom of the housing, and four spiral holes are provided on the connecting plate.

[0012] Furthermore, an alarm light is installed on the top of the housing, and the alarm light is electrically connected to contact point one, contact point two, contact point three and contact point four respectively.

[0013] Beneficial effects:

[0014] I. This utility model, through the setting of contact point one and contact point two, the connecting block and the slider are pre-compressed by the spring, so that the rectangular limiting block forms a dynamic lock after being inserted into the rectangular hole one. At the same time, contact point one and contact point two are kept separated under the tension of the barbed wire. When the barbed wire is cut by external force, contact point one and contact point two will contact and close under the action of the spring, thereby triggering the alarm. At the same time, the act of trying to pull the barbed wire will immediately force the slider to compress the spring, causing contact point three and contact point four to close, instantly triggering the alarm.

[0015] Second, with the setting of handle two, the barbed wire can be initially fixed by inserting the limiting block and the connecting block. The rectangular limiting block at the end of the barbed wire can only be unlocked by using a special threaded rod tool after the alarm is cleared. Conventional tools cannot operate the limiting block in the rectangular groove, thus physically preventing the possibility of illegal disassembly. During maintenance, the barbed wire can be safely disassembled by screwing the special threaded rod into the circular hole to lock it and then pulling it out, avoiding complicated tool operations.

A rectangular hole 108 is formed on the connecting block 107, and a rectangular groove 109 is formed on one side of the connecting block 107. A contact point 112 is mounted on the inner wall of each groove 103. A contact 105 is installed on the side of the slider 104 away from the spring 106. The contact 105 has the same size as the contact 2 112. A plate 113 is installed at the bottom of the connecting block 107. A contact 3 114 is installed on one side of the plate 113. Several plates 2 115 are installed on the inner wall of the housing 101. A contact 4 116 is installed on one side of the plate 2 115. The size of the contact 4 116 is the same as the size of the contact 3 114. An mounting block 110 is installed on the top of the connecting block 107. The mounting block 110 has a threaded hole 111.

[0027] As a technical optimization of this utility model, the outer side wall of the shell 101 is provided with a number of circular holes 117 and a number of rectangular holes 118.

[0028] As a technical optimization of this utility model, the installation component 200 includes a rod body 205 and a plurality of barbed wires 203. A handle 202 is installed at each end of the barbed wires 203. A rectangular limiting block 201 is installed at the end of the handle 202 away from the barbed wires 203. The length of the handle 202 is greater than the distance between the plate body 115 and the nearest rectangular hole 118.

[0029] As a technical optimization of this utility model, the size of the rectangular limiting block 201 is consistent with the size of the rectangular hole 108, the rectangular groove 109 and the rectangular hole 218.

[0030] As a technical optimization of this utility model, the outer wall of the rod 205 is provided with an external thread 204, and a handle 206 is installed at one end of the rod 205.

[0031] As a technical optimization of this utility model, the size of the external thread 204 is the same as the size of the threaded hole 111, and the size of the circular hole 117 is larger than the size of the rod body 205.

[0032] As a technical optimization of this utility model, a connecting plate 124 is installed at the bottom of the housing 101, and four spiral holes are opened on the connecting plate 124.

[0033] As a technical optimization of this utility model, an alarm light 102 is installed on the top of the housing 101, and the alarm light 102 is electrically connected to contact one 105, contact two 112, contact three 114 and contact four 116 respectively.

[0034] Working principle: In the initial installation state, the operator inserts the rectangular limiting blocks 201 at both ends of the barbed wire 203 into the rectangular holes 108 on the side wall of the housing 101 through the external threads 204 on the rod 205. By rotating the handle 202, the rectangular limiting blocks 201 are fixed to the inner side wall of the rectangular groove 109. The connecting block 107 is connected to the preload spring 106 through the slider 104, so that the limiting blocks are dynamically locked in the rectangular groove 109. At this time, the contact point... Contact 105 and contact 212 are kept separated by the force of spring 106 on slider 104. Contact 314 and contact 416 are also separated because plate 113 is not subjected to external force. When an intrusion occurs, the system triggers two response mechanisms. First, if the barbed wire 203 is cut, the tension applied to the connecting block 107 disappears, and spring 106 pushes slider 104 to move inward into groove 103, causing contact 105 and contact 212 to move inward. The contact closure forms a short circuit, triggering alarm light 102. Secondly, if an intruder attempts to pull the barbed wire 203 to forcibly break it, the increased pulling force will force the slider 104 to compress the spring 106 in the opposite direction through the connecting block 107, causing the plate 113 to move towards the plate 2 115, so that the contact 3 114 and contact 4 116 make instantaneous contact and close, which also triggers an immediate alarm. After the limit block is inserted, it is deeply hidden in the rectangular groove 109, which cannot be directly accessed by conventional tools. During maintenance or disassembly, the end of the rod 205 needs to be screwed into the circular hole 117 on the side wall of the housing 101 until the external thread 204 of the rod 205 locks with the internal thread hole 111 of the mounting block 110. At this time, pulling the handle 206 outward can simultaneously pull the connecting block 107 to overcome the resistance of the spring 106, so that the rectangular groove 109 is separated from the limit block, achieving safe disassembly. This process must be performed when the system is powered off and the alarm is cleared, which physically eliminates the possibility of disassembly by illegal tools.
