Description

Technical Field

[0001] This invention relates to the field of fence fixing, and in particular to an electronic fence device. Background Technology

[0002] The most advanced perimeter alarm system is the electronic fence, which mainly consists of three parts: the electronic fence host, front-end accessories, and the back-end control system. Typically, the electronic fence host is installed outdoors, along the existing fence (such as a brick wall, concrete wall, or iron fence). The pulse electronic fence host is also usually installed outdoors, transmitting alarm signals to the control keyboard at the back-end control center via signal transmission equipment. This displays the working status of the protected zone and allows for remote arming and disarming control of the external pulse host. Although electronic fences are frequently used for agricultural fencing and other forms of animal management, they are also widely used to enhance the security of military facilities, prisons, and other security-sensitive locations, even in areas where lethal voltages exist.

[0003] Existing electronic fences typically have a fixed height and cannot be freely adjusted. This means that if the height of the electronic fence needs to be increased or decreased, the entire fence must be replaced. When existing electronic fences are dismantled, if the metal wires are not removed, the fence will rotate under the tension of the metal wires during dismantling, causing safety accidents.

[0026] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0027] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0028] Example 1

[0029] Reference Figures 1-6 This is the first embodiment of the present invention, which provides a stackable electronic fence, specifically including: a power distribution cabinet 100, which includes a cabinet body 101, a protective cover 102, and a cabinet door 103. The cabinet body 101 is fixed to one side of a wall, the protective cover 102 is fixed above the cabinet body 101, and the cabinet door 103 is hinged to the cabinet body 101; a bottom fixing mechanism 200, which includes a universal base 201 and a fixing frame 202. The universal base 201 is fixed above the wall, and the fixing frame 202 is fixed to the universal base 201; a first fixing mechanism 300, which includes a pipe assembly 301 and a wire fixing assembly 302 disposed on the pipe wall of the pipe assembly 301; and a second fixing mechanism 400, which includes a sliding assembly 401 and a pressing assembly 402. The sliding assembly 401 is disposed in the pipe assembly 301, and the pressing assembly 402 is symmetrically disposed on both sides of the pipe assembly 301.

[0030] It should be noted that the cabinet 101 is a rectangular metal shell used to protect the internal components, the protective cover 102 is a double-sloped metal rain cap used to prevent rainwater from entering the cabinet 101; the cabinet door 103 is a metal door panel made of the same material as the cabinet 101.

[0031] Furthermore, a handle 103a is fixed on the cabinet door 103, and the handle 103a is located on the side of the cabinet door 103 away from the hinge; the universal base 201 includes a vertical plate 201a and a horizontal plate 201b, and the vertical plate 201a is perpendicular to the horizontal plate 201b; the pipe fixing assembly 301 includes a first pipe 301a and a second pipe 301b fixed above the first pipe 301a, and the axes of the first pipe 301a and the second pipe 301b coincide; the wire fixing assembly 302 includes a wire fixing seat 302a fixed to the side wall of the first pipe 301a, and a locking member 302b and a rotating member 302c slidably disposed in the wire fixing seat 302a.

[0032] It should be noted that the handle 103a is made of a solid cylindrical metal column; the vertical plate 201a is perpendicular to the top plane of the wall, and the horizontal plate 201b is parallel to the top plane of the wall. This arrangement allows the electronic fence to be perpendicular to the top plane of the wall when it is fixed; the first tube 301a is a round tube, and the second tube 301b is also a round tube. The diameter of the second tube 301b is larger than that of the first tube 301a, so that the first tube 301a can be inserted into the second tube 301b; the lock 302b is located on the side of the rotating part 302c.

[0033] Preferably, the first pipe fitting 301a includes a first pipe 301a-1 and a first fixing ring 301a-2 fixed to the bottom of the first pipe 301a-1, the first fixing ring 301a-2 and the first pipe 301a-1 having the same axis, and a sliding hole 301a-3 is also provided on the pipe body of the first pipe 301a-1; the second pipe fitting 301b includes a second pipe 301b-1 and a sealing ring 301b-2 fixed to the bottom of the second pipe 301b-1, the sealing ring 301b-2 and the second pipe 301b-1 having the same axis.

[0034] It should be noted that the first fixing ring 301a-2 is a circular ring, and the first pipe 301a-1 is a circular pipe. The diameter of the first pipe 301a-1 is smaller than the outer diameter of the first fixing ring 301a-2, and the outer diameter of the first fixing ring 301a-2 is equal to the inner diameter of the second pipe 301b-1. This is beneficial for maintaining the overall verticality of the first pipe fitting 301a when the first fixing ring 301a-2 is inserted into the second pipe 301b-1. The sliding hole 301a-3 is a circular hole. The diameter is much smaller than that of the first pipe 301a-1, which helps to maintain the overall strength of the first pipe 301a-1; the second pipe 301b-1 is a circular pipe, and the sealing ring 301b-2 is a circular ring. The outer diameter of the second pipe 301b-1 is equal to the outer diameter of the sealing ring 301b-2, and the inner diameter of the second pipe 301b-1 is larger than the inner diameter of the sealing ring 301b-2, so that the sealing ring 301b-2 can seal the connection between the first pipe 301a-1 and the second pipe 301b-1.

[0035] In this embodiment, the power distribution cabinet 100 can protect the internal components, and the universal base 201 can fix the first pipe 301a at different angles. The operator can fix the metal wire through the first fixing mechanism 300 and fix the entire stackable electronic fence through the second fixing mechanism 400. Before disassembling the stackable electronic fence, the first fixing mechanism 300 must be unlocked to loosen the metal wire.

[0036] Example 2

[0037] Reference Figures 1-6 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0038] Specifically, the vertical plate 201a has vertically arranged circular mounting holes 201a-1, and the horizontal plate 201b has horizontally arranged linear mounting holes 201b-1; the fixing bracket 202 is fixed to the vertically arranged mounting holes 201a-1 by bolts; the wire fixing base 302a includes a first circular segment 302a-1, a second circular segment 302a-2, and a square segment 302a-3, the first circular segment 302a-1, the second circular segment 302a-2, and the square segment 302a-3. The square segment 302a-3 is fixed in sequence; a fan groove M-1 is opened on the first circular segment 302a-1, a transverse groove M-2 communicating with the fan groove M-1 is opened at the connection between the first circular segment 302a-1 and the second circular segment 302a-2, and a sliding cavity M-3 communicating with the transverse groove M-2 is opened below the transverse groove M-2; a rotating hole M-4 communicating with the sliding cavity M-3 is opened through the middle of the square segment 302a-3, and a square groove M-5 is set between the rotating holes M-4.

[0039] It should be noted that the diameter of the vertical mounting hole 201a-1 is smaller than the diameter of the horizontal mounting hole 201b-1. The circular distribution of the vertical mounting holes 201a-1 allows the first pipe 301a-1 to change its fixed angle. The first circular segment 302a-1 is cylindrical in appearance, and the second circular segment 302a-2 is a circular tube. The outer diameter of the second circular segment 302a-2 is smaller than that of the first circular segment 302a-1, allowing the first circular segment 302a-1 to be mounted on the first pipe 301a-1. While ensuring a secure fixation, the weight of the second circular segment 302a-2 is reduced; the square segment 302a-3 has a square appearance; the fan groove M-1 is a fan-shaped groove, which facilitates the rotation of the locator 302b-2 within it, and the central angle of the fan groove M-1 is 90 degrees; the horizontal groove M-2 is a square straight groove, which allows the locator 302b-2 to slide horizontally within it; the sliding cavity M-3 is a cylindrical cavity, which facilitates the sliding and rotation of the disc 302b-1 within it; the rotating hole M-4 is a round hole; and the square groove M-5 is a rectangular groove.

[0040] In this embodiment, the operator must first fix the first pipe 301a-1 to the universal base 201 with bolts using the fixing bracket 202 before fixing the metal wires and stacking the electronic fence.

[0041] Furthermore, the lock 302b includes a disc 302b-1 slidably disposed in the slide cavity M-3, a pin 302b-2 fixed above the disc 302b-1, a connecting post 302b-3 coaxially fixed to the side of the disc 302b-1, a first spring 302b-4 sleeved on the outside of the connecting post 302b-3, and an elliptical cylinder 302b-5 coaxially fixed to the side of the connecting post 302b-3. The pin 302b-2 is slidably connected to the transverse groove M-2, and the connecting post 302b-3 is slidably connected to the slide hole 301a-3. The disc 302b-1 is also coaxially fixed with a ratchet ring 302b-6 on the side away from the connecting column 302b-3; the rotating component 302c includes a rotating column 302c-1, a locking pin 302c-2 coaxially fixed in the middle of the rotating column 302c-1, and a twist cap 302c-3 and a ratchet wheel 302c-4 fixed on both sides of the rotating column 302c-1. The locking pin 302c-2 is located in the square segment 302a-3, and the ratchet wheel 302c-4 is slidably arranged in the middle of the ratchet ring 302b-6; a wire groove is opened through the middle of the locking pin 302c-2.

[0042] It should be noted that the disc 302b-1 is cylindrical, and its diameter is the same as that of the sliding cavity M-3, facilitating smooth sliding of the disc 302b-1 within the cavity M-3; the lever 302b-2 is a rectangular prism, with one end fixed to the outside of the disc 302b-1; the first spring 302b-4 has one end in contact with the disc 302b-1 and the other end in contact with the inside of the sliding cavity M-3; the elliptical cylinder 302b-5 is elliptical in shape overall, therefore... The cylinder 302b-5 can change its vertical length when rotated; the rotating column 302c-1 and the locking column 302c-2 are cylinders, with the diameter of the rotating column 302c-1 being smaller than that of the locking column 302c-2, which prevents the locking column 302c-2 from sliding out of the rotating hole M-4; the twist cap 302c-3 is a rectangular cylinder, with the long side of the twist cap 302c-3 being longer than the diameter of the locking column 302c-2, making it easier for the operator to operate; the wire groove is a rectangular through groove, which is conducive to the passage of metal wires.

[0043] Preferably, the sliding assembly 401 includes a limiting post 401a fixed in the first pipe 301a-1, a transmission post 401b slidably disposed outside the limiting post 401a, and a second spring 401c fixed between the limiting post 401a and the transmission post 401b; the transmission post 401b has a first through hole 401b-1 and a second through hole 401b-2 located below the first through hole 401b-1, the first through hole 401b-1 is slidably connected to the elliptical cylinder 302b-5, and the second through hole 401b-2 is slidably connected to the limiting post 401a; the extrusion assembly 402 includes a limiting frame 402a fixed to the inner side of the bottom of the first pipe 301a-1, and a rubber block 402b slidably disposed in the limiting frame 402a, the rubber block 402b being limited in the limiting frame 402a by a limiting block.

[0044] It should be noted that the limiting post 401a is a rectangular prism, and it connects to the inside of the first pipe 301a-1 in the diameter direction, allowing it to be firmly fixed inside the first pipe 301a-1; the transmission post 401b is a rectangular prism, and its bottom is rounded, which makes the bottom of the transmission post 401b smoother when compressing the rubber block 402b; the first through hole 401b-1 is a square hole. The side length of the first through hole 401b-1 is equal to the length of the major axis of the elliptical cylinder 302b-5, so that the transmission column 401b cannot slide up and down when the elliptical cylinder 302b-5 is rotated to the vertical position; the second through hole 401b-2 is a rectangular hole, and the length of the second through hole 401b-2 is longer than that of the first through hole 401b-1, so that there is space for the second spring 401c to extend and retract inside the second through hole 401b-2; the limiting frame 402a is a square frame, which matches the shape of the rubber block 402b, and the rubber block 402b is a square block.

[0045] In this embodiment, when the operator needs to dismantle the electronic fence, the push pin 302b-2 must first be pushed, causing it to slide from the side of the transverse groove M-2 away from the fan groove M-1 to the side closer to the fan groove M-1. During this process, the ratchet ring 302b-6 will slide together with the push pin 302b-2 until it no longer contacts the ratchet wheel 302c-4. The ratchet wheel 302c-4, now freed from the restraint of the ratchet ring 302b-6, will rotate under the tension of the metal wire on the locking pin 302c-2 until the metal wire returns to straight. The push pin 302b-2... After sliding into the fan slot M-1, the operator needs to rotate the lever 302b-2 from the side of the fan slot M-1 closest to the horizontal slot M-2 to the side away from the horizontal slot M-2. During this process, the elliptical cylinder 302b-5 will rotate together with the lever 302b-2, rotating from the major axis perpendicular to the horizontal plane to the minor axis perpendicular to the horizontal plane. After the compression of the elliptical cylinder 302b-5 is removed, the transmission column 401b will rise under the elastic force of the second spring 401c. At the same time, the rubber block 402b loses the compression of the transmission column 401b, and the operator can pull out the stackable electronic fence.

[0046] It should be noted that when the operator needs to install the stackable electronic fence, the first pipe 301a-1 must first be inserted into the second pipe 301b-1 of the first fixing mechanism 300 of the other, and then the lever 302b-2 is rotated so that the lever 302b-2 rotates from the side away from the horizontal groove M-2 in the fan groove M-1 to the side close to the horizontal groove M-2. After that, the elliptical cylinder 302b-5 will press down on the first through hole 401b-1, so that the transmission column 401b presses the rubber block 402b on both sides. Finally, the stackable electronic fence is fixed by the friction between the rubber block 402b and the second pipe 301b-1. After that, the operator releases the handle, and the ratchet ring 302b-6 will be put into the outside of the ratchet 302c-4 under the elastic force of the first spring 302b-4. Finally, the operator can insert the metal wire from the locking column 302c-2 and tighten the metal wire by rotating the twist cap 302c-3.

[0047] It should be understood that numerous specific implementation decisions can be made during the development of any practical implementation, such as in any engineering or design project. Such development efforts may be complex and time-consuming, but for those skilled in the art who benefit from this disclosure, the development effort will be a routine work of design, manufacturing, and production without requiring much experimentation.

[0048] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
