Description

Technical Field

[0001] The utility model relates to the technical field of electronic fences, in particular to a tension tightening device for an electronic fence. Background Technique

[0002] An electronic fence is the most advanced perimeter anti-theft alarm system. It consists of an electronic fence host and a front-end detection fence. An electronic fence is an active intrusion prevention fence that counterattacks against intrusion attempts, repels intruders, delays the intrusion time, does not threaten human life, and sends the intrusion signal to the monitoring equipment of the security department to ensure that the management personnel can timely understand the situation of the alarm area and make quick handling.

[0003] During the adjustment process of the electronic fence, it is necessary to adjust the loose alloy wire to make the alloy wire taut. The tension tightening device cannot callback the alloy wire during the subsequent disassembly process. It is necessary for the staff to disassemble one end of the tightening device to callback the alloy wire. However, during the disassembly process, the self-tension of the alloy wire will cause it to quickly rebound. Therefore, there is a high possibility of potential safety hazards. At the same time, after the tension tightening device adjusts the alloy wire, it will increase the disassembly burden on the staff. Summary of the Invention

[0004] The purpose of the utility model is to provide a tension tightening device for an electronic fence to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A tension tightening device for an electronic fence, including a housing, a main rod and a ratchet. There are two groups of wire passing holes on both sides of the housing. There is a chute on the back of the housing. There is a spring hole at the bottom of the front of the housing. A spring member is installed on the front of the spring hole. A ratchet is installed on one side inside the housing. The main rod is installed through the inside of the ratchet. There is a wire winding hole on the front of the main rod. There is a mounting hole at one end of the main rod. A clamping rod is installed through the mounting hole. A pawl is installed on the side of the housing away from the main rod. There is a clamping hole on one side of the front of the pawl. A fixing bolt is installed on the front of the pawl. A clamping ring is installed inside the housing. A wire removing rod is installed through the inside of the clamping ring. One end of the wire removing rod extends out of the back of the housing and is installed with a push plate.

[0006] Preferably, there is a reserved hole on one side of the front of the housing.

[0007] Preferably, one end of the spring member contacts the clamping hole.

[0008] Preferably, one side of the ratchet contacts the pawl.

[0009] Preferably, one end of the fixing bolt penetrates to the back of the housing, and a fixing nut is installed on the fixing bolt through a threaded structure.

[0010] Preferably, a gasket is placed on the back of the housing.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] 1. When the thread removal rod moves upward, it can push the ratchet pawl upward. When the ratchet pawl moves upward, the ratchet wheel rotates due to the self-elasticity of the alloy wire. When the ratchet wheel rotates in reverse, it will drive the main rod to rotate. The rotation of the main rod can loosen the alloy wire, so that it is convenient for the staff to quickly disassemble the device from the alloy wire, without the need for the staff to disassemble the whole main rod and then callback the alloy wire.

[0013] 2. By pulling out the clamping rod installed in the drawing hole, when the clamping rod is pulled out of the drawing hole, it is convenient for the staff to disassemble the main rod, so that it is convenient for the staff to quickly replace the main rod or the ratchet wheel, reducing the burden of the staff during the disassembly process of the device, and at the same time improving the overall disassembly efficiency of the device by the staff.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] The technical solutions of the present utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0020] Embodiment 1

[0021] As Figures 1-4As shown in the figure, a tension tightening device for an electronic fence proposed by the present utility model includes a housing 1, a main rod 3 and a ratchet 4. Two groups of wire passing holes 101 are provided on both sides of the housing 1. A sliding groove 104 is provided on the back of the housing 1. A spring hole 102 is provided at the bottom of the front of the housing 1. A spring member 2 is installed on the front of the spring hole 102. A ratchet 4 is installed on one side inside the housing 1. The main rod 3 is installed through the inside of the ratchet 4. A wire winding hole 301 is provided on the front of the main rod 3. An installation hole 302 is provided at one end of the main rod 3. A clamping rod 6 is installed through the installation hole 302. A pawl 5 is installed on the side of the housing 1 away from the main rod 3. A clamping hole 501 is provided on one side of the front of the pawl 5. A fixing bolt 502 is installed on the front of the pawl 5. A clamping ring 8 is installed inside the housing 1. A wire removing rod 801 is installed through the inside of the clamping ring 8. One end of the wire removing rod 801 extends out of the back of the housing 1 and is installed with a push plate 802.

[0022] Furthermore, a reserved hole 103 is provided on one side of the front of the housing 1.

[0023] Furthermore, one end of the spring member 2 is in contact with the clamping hole 501.

[0024] Furthermore, one side of the ratchet 4 is in contact with the pawl 5.

[0025] Furthermore, one end of the fixing bolt 502 penetrates to the back of the housing 1, and a fixing nut 503 is installed on the fixing bolt 502 through a threaded structure.

[0026] Furthermore, a gasket 7 is placed on the back of the housing 1.

[0027] The working principle of the tension tightening device for the electronic fence based on Embodiment 1 is as follows: After the staff passes the alloy wire through the wire threading hole 101 into the inside of the housing 1, the alloy wire is simultaneously passed into the wire winding hole 301 provided on the front of the main rod 3, and at the same time, the alloy wire is passed out from the wire threading hole 101 at the other end of the housing 1, so as to install the device on the surface of the alloy wire. When the staff needs to adjust the tightness of the alloy wire, the main rod 3 can be rotated. During the rotation of the main rod 3, the alloy wire can be wound on the surface of the main rod 3. At the same time, when the main rod 3 rotates, it will drive the ratchet 4 to rotate. During the rotation of the ratchet 4, it can drive the pawl 5 to move. When the pawl 5 moves, it can drive the pawl 5 to reset through the spring member 2 to fix the ratchet 4, avoiding the main rod 3 from rotating when the alloy wire rebounds. By fixing the ratchet 4, the main rod 3 can be fixed, ensuring the stability of the main rod 3 during the tightness adjustment of the alloy wire. If the staff needs to loosen the alloy wire, the push plate 802 can be pushed upward. When the push plate 802 moves upward, it can drive the wire removing rod 801 to move upward. When the wire removing rod 801 moves upward, it can push the pawl 5 to move upward. When the pawl 5 moves upward, the ratchet 4 rotates back due to the elastic force of the alloy wire itself. When the ratchet 4 rotates backward, it will drive the main rod 3 to rotate backward. The rotation of the main rod 3 can loosen the alloy wire, so that it is convenient for the staff to quickly disassemble the device from the alloy wire, without the staff having to disassemble the whole main rod 3 to adjust the alloy wire back. When the staff needs to disassemble the device, the clamping rod 6 installed in the installation hole 302 can be pulled out. When the clamping rod 6 is pulled out of the installation hole 302, it is convenient for the staff to disassemble the main rod 3, so that it is convenient for the staff to quickly replace the main rod 3 or the ratchet 4, reducing the burden of the staff during the disassembly process of the device and improving the overall disassembly efficiency of the staff.

[0028] The above specific embodiments are merely several preferred embodiments of the present invention.
