Description

Technical Field

[0001] This utility model relates to the field of tension-type electronic fence technology, specifically to an elastic mechanism and a tension-type electronic fence. Background Technology

[0002] Tension-type electronic fences are a type of perimeter intrusion alarm system, mainly consisting of components such as tension detectors, alarms, surge arresters, tension springs, tension wire tensioners, support poles, load-bearing poles, warning signs, and steel wire ropes. The tension springs absorb external impacts, prevent alloy wire breakage or slackening, maintain stable system tension through elastic deformation, and adapt to environmental changes such as thermal expansion and contraction.

[0003] The existing tension spring is a common extension spring, with a deformation part in the middle and connecting parts at both ends. The deformation part can deform and is the core part of the spring. The connecting parts at both ends are C-shaped hooks and O-shaped loops, respectively. The hooks are used to directly hook the rod body. The loops are used to connect the steel wire rope that comes out from the tensioner. One end of the steel wire rope is wrapped around the loop and then fixed by the cable tie.

[0004] The deformation part of the existing tension spring is exposed, while the fence is usually installed on the wall, close to trees and other places. This makes the tension spring very susceptible to corrosion and aging by rainwater, bird droppings and other factors, which affects its elastic deformation ability. When its performance stability decreases, false alarms may occur, which reduces the stability of the fence. Utility Model Content

[0005] This utility model provides an elastic mechanism and a tension electronic fence. The elastic mechanism can overcome the defect of existing technology where springs are easily corroded, affecting the stability of the fence.

[0006] According to the present invention, an elastic mechanism includes a mechanism body; the mechanism body includes a spring capable of deformation; both ends of the spring are provided with connectors; hooks and hanging rings for connecting the fence post and the wire rope are respectively provided at the two connectors. The mechanism body also includes a protective component for enclosing the spring; a fixing component for positioning the protective component is provided at the connector.

[0007] The protective component and fixing assembly of this utility model can wrap the spring to prevent rainwater or other corrosive objects from directly contacting the surface of the spring and ensuring the life of the spring. This can reduce the replacement cycle of the elastic mechanism, because the elastic mechanism is not only connected to the fence post but also to the wire rope through the cable tie, which is time-consuming to replace and requires tension adjustment after replacement. Reducing the replacement cycle can reduce trouble.

[0008] Preferably, the protective component is a flexible plastic diaphragm, which is wrapped around the two connectors to wrap the spring.

[0009] In this invention, the protective component made of plastic diaphragm is easier to obtain and less expensive; and the flexible plastic diaphragm can expand and contract like a corrugated pipe. When the steel wire rope deforms and causes the spring to deform, resulting in a change in the distance between the two connectors, the protective component can adapt to the expansion and contraction and always wrap around the spring.

[0010] Preferably, the protective component is a deformable plastic cylinder that unfolds into a C-shape and is fitted over the two connectors to enclose the spring.

[0011] In this invention, the protective component made of a plastic cylinder allows the component to be directly fitted onto the two connectors after being opened into a C-shape, thus enabling faster installation compared to a plastic diaphragm.

[0012] Preferably, the protective component is a stainless steel cylinder that can deform and unfold into a C-shape, and is fitted over the two connectors to enclose the spring.

[0013] In this invention, the stainless steel cylinder provides higher strength, is less prone to breakage, and has a longer lifespan compared to a plastic cylinder.

[0014] Preferably, the connector is cylindrical; the fixing component includes a plurality of pressure plates arranged in a ring array on the periphery of the connector; the pressure plates are elastic and fixed to the connector at one end; one side of the pressure plate and the periphery of the connector form a clamping area for clamping and fixing the end of the protective component.

[0015] In this invention, the pressure plate is designed so that the protective component can be pressed down by the pressure plate after wrapping the spring, thus preventing the protective component from easily falling off due to vibration, wind, or other factors.

[0016] Preferably, multiple pressure plates are wound together with a steel wire rope, which is used to give the pressure plates a tendency to be circumferentially squeezed toward the connector.

[0017] In this invention, the steel wire rope allows for higher pressure on the protective component from the pressure plate, thereby further enhancing the stability of the protective component.

[0018] A tension electronic fence comprising any of the elastic mechanisms described above. Attached Figure Description

Detailed Implementation

[0020] To further understand the content of this utility model, a detailed description of the utility model is provided in conjunction with the embodiments. It should be understood that the embodiments are merely illustrative and not limiting of the utility model.

[0021] Example 1 like Figure 1-4 As shown, this embodiment provides an elastic mechanism, which includes a mechanism body 100; the mechanism body 100 includes a spring 260 capable of deformation; both ends of the spring 260 are provided with connectors 150; the two connectors 150 are respectively provided with hooks 110 and hanging rings 120 for connecting the fence pole and the wire rope 242. The mechanism body 100 also includes a protective member 130 for enclosing the spring 260; a fixing component 140 for positioning the protective member 130 is provided at the connector 150.

[0022] The protective component 130 and the fixing component 140 in this embodiment can wrap the spring 260 to prevent rainwater or other corrosive objects from directly contacting the surface of the spring 260, thus ensuring the life of the spring 260. This can reduce the replacement cycle of the elastic mechanism, because the elastic mechanism is not only connected to the fence post but also to the wire rope 242 through the cable tie, which is time-consuming to replace. After replacement, tension adjustment and other operations are required. Reducing the replacement cycle can reduce trouble.

[0023] In this embodiment, the protective component 130 is a flexible plastic film, which is wrapped around the two connectors 150 to wrap the spring 260.

[0024] The protective element 130 of the plastic diaphragm in this embodiment is easier to obtain and has a lower cost; and the flexible plastic diaphragm can expand and contract like a corrugated pipe. When the steel wire rope 242 deforms and causes the spring 260 to deform, causing the distance between the two connectors 150 to change, the protective element 130 can adapt to the expansion and contraction and always wrap around the spring 260. The plastic film is similar to a plastic bag; it can be obtained by cutting up a plastic bag when materials are scarce. Its dimensions are as follows: Figure 1-4As shown, extra length needs to be reserved to accommodate the extension and retraction of the spring 260, i.e., the change in the distance between the two connectors 150. It can be wrapped around the two connectors 150 multiple times. Because it is light and easily deformed, it is necessary to tie the pressure plate 241 with steel wire rope 242 to prevent the plastic film from falling off.

[0025] In this embodiment, the connector 150 is cylindrical; the fixing component 140 includes a plurality of pressure plates 241 arranged in a ring array on the periphery of the connector 150; the pressure plates 241 are elastic and fixed to the connector 150 at one end; one side of the pressure plate 241 and the periphery of the connector 150 form a clamping area 243 for clamping and fixing the end of the protective member 130.

[0026] By setting the pressure plate 241 in this embodiment, the protective component 130 can be pressed down by the pressure plate 241 after wrapping the spring 260 to achieve stability, thereby preventing the protective component 130 from easily falling off due to vibration, wind and other factors; wherein the connector 150 is shaped like a bottle cap, and the end of the tension spring is welded to the concave surface of the connector 150.

[0027] In this embodiment, multiple pressure plates 241 are wound together with a steel wire rope 242, which is used to make the pressure plates 241 tend to be circumferentially squeezed toward the connector 150.

[0028] By using the steel wire rope 242 in this embodiment, the pressure of the pressure plate 241 on the protective component 130 is increased, thereby further improving the stability of the protective component 130.

[0029] A tension electronic fence, comprising any of the elastic mechanisms described above. Example 2 like Figure 5 As shown, this embodiment differs from Embodiment 1 in that: In this embodiment, the protective component 130 is a plastic cylinder that can deform and unfold into a C-shape, and is fitted onto the two connectors 150 to wrap the spring 260.

[0030] The protective component 130 of the plastic cylinder in this embodiment allows the protective component 130 to be directly fitted onto the two connectors 150 after being opened into a C-shape, thus enabling faster installation compared to a plastic diaphragm.

[0031] The plastic cylinder is made of a flexible, transparent plastic material. Its inner diameter must match the outer diameter of the connector 150, and its length must be greater than the distance between the two connectors 150 to accommodate changes in their spacing. It needs to be custom-made compared to the plastic diaphragm in Example 1. During installation, pull open the two connectors 150 to open the plastic cylinder into a C-shape and place it on the spring 260. Then release the plastic cylinder to restore its cylindrical shape. Release the two connectors 150 again; at this point, both ends of the plastic cylinder are pressed against the end faces of multiple pressure plates 241. Finally, lift one end face of the pressure plate 241 to... When bent and deformed, the end of the plastic cylinder can extend into the clamping area 243 formed between the pressure plate 241 and the connector 150, thus completing the installation. Because the plastic film in Example 1 does not easily recover automatically when bent, while the plastic cylinder always tends to recover after bending, the two ends of the plastic film can adapt to expansion and contraction even after being pressed by the wire rope 242 after being wrapped. The plastic film does not need to be tied with the wire rope 242. After tying the wire rope 242, it is easy for the two connectors 150 to be difficult to move, and the spring 260 cannot adapt to expansion and contraction according to the tension of the wire in the fence.

[0032] Example 3 The difference between this embodiment and Embodiments 1 and 2 is that: In this embodiment, the protective component 130 is a stainless steel cylinder that can deform and unfold into a C-shape, and is fitted onto the two connectors 150 to wrap the spring 260.

[0033] The stainless steel cylinder in this embodiment is stronger, less prone to breakage, and has a longer lifespan compared to a plastic cylinder.

[0034] The stainless steel cylinder can be a cylinder made of 260 stainless steel springs, which has a longer lifespan compared to the plastic material used in Examples 1 and 2; its shape is similar to... Figure 5 Consistent with the above.

[0035] It is readily understood that those skilled in the art can combine, split, or reorganize the embodiments provided in this application to obtain other embodiments, all of which do not exceed the protection scope of this application.

[0036] The present invention and its embodiments have been described above illustratively. This description is not restrictive, and the embodiments shown are only part of the embodiments of the present invention. The actual structure is not limited to this. Therefore, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
