Description

Technical Field

[0001] The invention relates to the technical field of matching parts, in particular to an equipment wire clamp with an anti-breaking structure. Background Art

[0002] In key areas such as power transmission, communications, and the connection of various industrial equipment, equipment clamps play an indispensable role as important components for achieving reliable connection between wires and electrical equipment. However, the current equipment clamps on the market have exposed a series of problems that need to be solved in actual applications, among which the problem of wire breakage is the most prominent.

[0003] During long-term service, traditional equipment wire clamps need to continuously withstand the combined effects of multiple external forces such as the wire's own gravity, wind force, thermal expansion and contraction. During this process, stress concentration is very likely to occur at the contact point between the wire clamp and the wire. Over time, this stress concentration continues to accumulate, gradually weakening the structural strength of the wire and eventually causing the wire to break. This not only seriously threatens the stability and reliability of power transmission or signal transmission, but may also cause serious safety accidents and cause immeasurable losses.

[0004] In order to solve the problem of wire breakage, many explorations have been made in the relevant technical field. For example, the patent publication number CN111509480B discloses a device for preventing wire clamps from breaking. When the wire clamp cable of the equipment is subjected to a swinging external force, the device limits the range of movement of the cable through multiple symmetrically arranged springs and absorbs the external force, thereby preventing the cable from breaking, while also solving the problem of disconnection between the wire and the clamp. However, after an in-depth analysis of the above patents and other existing technologies, it is still found that there are many defects.

[0005] First, the existing technology has poor anti-breaking effect, and the tensile force that can be sustained when breaking occurs is too low, which makes it difficult to meet the growing demand for high-intensity use. Second, the trigger part of some anti-breaking structures is installed inside the wire clamp body. When the wire clamp becomes loose, it will have an adverse effect on the trigger, reducing the effectiveness of the anti-breaking mechanism. Third, if the trigger part of the anti-breaking structure is set outside the wire clamp body, it will affect the installation efficiency of the wire clamp, increase the construction difficulty and time cost. Fourth, wire clamps generally have poor dust and water resistance, which makes it easy for external dust, moisture and other impurities to invade, further corrode the wires and wire clamps, accelerate their damage, and reduce their service life.

[0006] In summary, the existing equipment wire clamp anti-breaking technology has many shortcomings, which seriously restricts its efficient and stable application in various fields. Therefore, it is of great practical significance and application value to develop a new equipment wire clamp anti-breaking structure with excellent anti-breaking effect, reliable trigger mechanism, efficient installation method and good dustproof and waterproof performance. Summary of the invention

[0007] 1. Technical issues to be resolved In view of the shortcomings of the prior art, the present invention provides an equipment wire clamp with an anti-breaking structure, which has the advantages of multiple anti-breaking structures, long service life, simple and convenient installation, and good waterproof and dustproof effects. It solves the problems of poor anti-breaking effect, too low tensile force that can be tolerated when breaking, short service life, low installation efficiency, and poor waterproof and dustproof effects in the prior art.

[0008] (II) Technical solution To achieve the above object, the present invention provides the following technical solutions: A device wire clamp with an anti-breaking structure, comprising a wire clamp body, a wire placement groove for clamping a wire core is arranged on the wire clamp body, two arcuate wire pressing plates are arranged on the wire placement groove, a locking groove is arranged at a position between the two arcuate wire pressing plates, a locking ring is detachably fixed on the wire core, the locking ring is clamped in the locking groove and slides, and the locking ring receives the limiting structure of the arcuate wire pressing plate to form a primary anti-breaking structure; The outside of the wire clamp body is wrapped with a dust cover, and the dust cover includes an outer tube and an inner tube that are connected inside and outside. The inner tube is connected to a locking ring, and the locking ring drives the inner tube to slide. A secondary anti-breaking structure is also provided on the inner tube and the outer tube. When the inner tube and the outer tube slide relative to each other, the secondary anti-breaking structure clamps the wire core.

[0009] Preferably, four double-headed clamps are arranged on the circumference of one end of the outer cylinder close to the wire core, the middle part of the double-headed clamp is rotatably connected to the outer cylinder, and a locking head is arranged on one end of the double-headed clamp close to the wire clamp body; The inner cylinder is provided with a top block, and when the locking ring drives the inner cylinder to slide outward, the top block pushes the locking head inward, and the locking head is clamped on the wire core to limit the sliding of the wire core; The double-head clamping body and the top block are combined to form a secondary anti-breakage structure.

[0010] Preferably, an elastic head is provided at one end of the double-headed clamp body away from the wire clamp body, and a supporting spring is also provided between the elastic head and the outer tube for fitting the elastic head onto the wire core. Under normal circumstances, the elastic head provides elastic supporting force for the wire core to reduce the risk of wire core breakage. When the secondary anti-break structure is triggered to make the locking head clamp the wire core inward, the elastic head is driven to rotate outward to separate from the wire core, providing a larger moving space for the wire core and reducing the pressure on the anti-break structure.

[0011] Preferably, a four-part groove is provided at the end of the inner tube corresponding to the position of the double-headed clamp body, and the four-part groove divides the end of the inner tube into four separate four-part tubes. A top block is provided at the bottom of the four-part groove, and four through holes and four double-headed clamp bodies are combined to seal the end of the outer tube close to the wire core. An end cover is provided at the end of the outer tube close to the wire clamp body, and the end cover is connected and fixed to the outer tube and the wire clamp body, so that the dust cover remains sealed.

[0012] Preferably, a locking rod is provided on the inner cylinder, and the locking ring includes an outer ring and an inner ring connected by threads, a plurality of elastic grooves are provided at the end of the inner ring, a pressing sheet is provided on the inner side of the end of the inner ring, and a locking hole is provided on the outer side of the outer ring, and the locking rod is clamped in the locking hole to connect the locking ring and the inner cylinder.

[0013] Preferably, a slide groove is provided on the inner cylinder, a slider is slidably connected in the slide groove, the locking rod is fixed inside the slider, a cylinder is also fixed in the inner cylinder, and the push-pull rod end of the cylinder is connected to the slider;

[0014] A temperature sensor is arranged in the inner cylinder; There are perforations on the side of the end of each quarter-tube, and fans are installed in the quarter-tubes at two symmetrical positions. When the temperature sensor detects that the temperature is too high, the cylinder pushes the slider to make the inner tube slide actively, and the fan in the quarter-tube is started for heat dissipation. The four separately arranged quarter-tubes have the air inlet and outlet spaced apart, which improves the fluidity of the air flow, and the perforations are hidden in the outer tube under normal circumstances to prevent dust from entering.

[0015] Preferably, a warning light is also provided on the side of each quarter tube.

[0016] Preferably, the inner cylinder is made of insulating material, and the outer cylinder is made of metal.

[0017] Preferably, a rubber layer is provided on the contact surface of the elastic head and the locking head with the wire core.

[0018] Preferably, a through groove is provided at the bottom of the locking groove, and the lock hole passes through the through groove.

[0019] (III) Beneficial effects Compared with the prior art, the present invention provides an equipment wire clamp with an anti-breaking structure, which has the following beneficial effects: 1. The equipment wire clamp with an anti-breaking structure has a locking ring arranged on the wire core. The locking ring is stuck in the locking groove between the two bow-shaped wire pressing plates and slides. The locking ring is not subjected to force under normal conditions. Only when the wire core slides, that is, when the connection of the wire clamp body is loosened, the locking ring slides to the bow-shaped wire pressing plate on the rear side to act as a limiting structure, that is, the first anti-breaking structure. It only needs to install the locking ring on the wire core and then fix the wire core in the wire groove. The installation is simple and convenient, and the installation efficiency will not be affected by the anti-breaking structure.

[0020] 2. The equipment wire clamp with an anti-breaking structure has a locking ring connected to the inner cylinder. When the locking ring moves, it triggers the secondary anti-breaking structure composed of the inner cylinder and the outer cylinder. Since the locking ring is not subjected to force under normal conditions and has a long service life, the triggering of the secondary anti-breaking structure is stable and not prone to failure. At the same time, the dust cover is set to a double-layer structure composed of an outer cylinder and an inner cylinder, which improves the protective effect of the dust cover.

[0021] 3. The equipment wire clamp with an anti-breaking structure has a secondary anti-breaking structure composed of a top block on the inner cylinder and a double-headed clamp body on the outer cylinder. An elastic head and a locking head are respectively arranged at both ends of the double-headed clamp body. Under normal circumstances, the elastic head is placed on the wire core to provide support. When the wire core slides, the top block pushes the locking head inward so that the locking head clamps the wire core to play a secondary anti-breaking role. At the same time, the elastic head is separated from the wire core to give the wire core a larger space for movement, thereby preventing the wire core from collapsing too tightly and reducing the tension on the anti-breaking structure.

[0022] 4. The equipment wire clamp with an anti-breaking structure is provided with a four-part groove at the position of the double-headed clamp body at the end of the inner tube. The four-part groove divides the inner tube into four four-part tubes. The four-part tubes and the double-headed clamp body play the role of sealing the end of the outer tube. At the same time, an end cover is provided at the other end to keep the dust cover sealed under normal conditions, thereby achieving a waterproof and dustproof effect. The dust cover wraps the part of the wire clamp body that is connected to the wire core, thereby extending the service life of the wire clamp body.

[0023] 5. The equipment wire clamp with an anti-break structure can also be equipped with warning lights, alarms or perforations on the side of the quarter-tube. Under normal circumstances, these parts are hidden in the outer tube and are only exposed to the outside when the inner tube slides out, thereby improving the sealing effect under normal circumstances. In addition, a cylinder can be arranged in the inner tube to actively push the inner tube to move, and a fault in the dust cover can be detected through a detection device, thereby actively cooling and alarming. At the same time, the four separate quarter-tubes set the air inlet and the air outlet at intervals, thereby improving the gas flow during heat dissipation. BRIEF DESCRIPTION OF THE DRAWINGS

In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0042] Embodiment 1: This embodiment provides an equipment wire clamp with an anti-breakage structure, which has the following technical features.

[0043] See also Figure 1-13 , a device wire clamp with an anti-breaking structure, comprising a wire clamp body 2, the wire clamp body 2 is provided with a wire placement groove 21 for clamping a wire core 1, the wire placement groove 21 is also provided with two arched wire pressing plates 22, the wire placement groove 21 is provided with a locking groove 23 at a position between the two arched wire pressing plates 22, a locking ring 4 is detachably fixed on the wire core 1, the locking ring 4 is stuck in the locking groove 23 and slides, and the locking ring 4 receives the limiting structure of the arched wire pressing plate 22 to form a primary anti-breaking structure; The outer side of the wire clamp body 2 is wrapped with a dust cover 3, and the dust cover 3 includes an outer tube 31 and an inner tube 32 which are connected inside and outside. The inner tube 32 is connected to a locking ring 4, and the locking ring 4 drives the inner tube 32 to slide. A secondary anti-breaking structure is also provided on the inner tube 32 and the outer tube 31. When the inner tube 32 and the outer tube 31 slide relative to each other, the secondary anti-breaking structure clamps the wire core 1.

[0044] It is further provided that the inner cylinder 32 is made of insulating material, and the outer cylinder 31 is made of metal material.

[0045] It should be noted that the inner tube 32 is made of mica board, which is made of mica sheets or mica powder, adhesives and reinforcing materials. The outer tube 31 is made of aluminum alloy, which has good compression, tension and impact resistance, can effectively protect the internal insulation layer and wire clamp from external damage, has good corrosion resistance, and easily forms a dense oxide film on the surface, which can prevent corrosion by rain, air, etc., prolongs its service life, and is light in weight. Compared with other metal materials, aluminum alloy is lighter in weight, easier to install and maintain, and reduces construction difficulty and cost.

[0046] By setting the above structure, the equipment wire clamp with an anti-breaking structure has a locking ring 4 on the wire core 1, and the locking ring 4 is stuck in the locking groove 23 between the two arched wire pressing plates 22 and slides. The locking ring 4 is not subjected to force under normal conditions. Only when the wire core 1 slides, that is, when the connection of the wire clamp body 2 is loose, the locking ring 4 slides to the arched wire pressing plate 22 on the rear side to act as a limiting structure, that is, the first anti-breaking structure. It is only necessary to install the locking ring 4 on the wire core 1 and then fix the wire core 1 in the wire groove 21. The installation is simple and convenient, and the installation efficiency will not be affected by the anti-breaking structure.

[0047] In addition, the locking ring 4 is connected to the inner cylinder 32. When the locking ring 4 moves, it triggers the secondary anti-breakage structure composed of the inner cylinder 32 and the outer cylinder 31. Since the locking ring 4 is not subjected to force under normal circumstances and has a long service life, the triggering of the secondary anti-breakage structure is stable and not prone to failure. At the same time, the dust cover 3 is set to a double-layer structure composed of the outer cylinder 31 and the inner cylinder 32, thereby improving the protective effect of the dust cover 3.

[0048] Further, the outer cylinder 31 is provided with four double-headed clamp bodies 311 on the circumference of one end close to the wire core 1, the middle part of the double-headed clamp body 311 is rotatably connected to the outer cylinder 31, and the double-headed clamp body 311 is provided with a locking head 3112 on one end close to the wire clamp body 2;

[0049] The inner cylinder 32 is provided with a top block 323. When the locking ring 4 drives the inner cylinder 32 to slide outward, the top block 323 pushes the locking head 3112 inward, and the locking head 3112 is stuck on the wire core 1 to limit the sliding of the wire core 1. The double-head clamp body 311 and the top block 323 are combined to form a secondary anti-breakage structure.

[0050] It should be noted that four fixedly connected rotating seats are arranged on the outer cylinder 31 , and the fixed connection method can be one-piece forming or gluing. The rotating seat has the same width as the double-headed clamp 311 , and the two sides are flush, and there is no gap at the rotating connection.

[0051] Furthermore, an elastic head 3111 is provided at one end of the double-headed clamp body 311 away from the clamp body 2, and a supporting spring 3113 is also provided between the elastic head 3111 and the outer tube 31, for fitting the elastic head 3111 onto the wire core 1. Under normal circumstances, the elastic head 3111 provides elastic supporting force for the wire core 1 to reduce the risk of breakage of the wire core 1. When the secondary anti-breaking structure is triggered to make the locking head 3112 clamp the wire core 1 inward, the elastic head 3111 is driven to rotate outward to separate from the wire core 1, thereby providing a larger activity space for the wire core 1 and reducing the pressure of the anti-breaking structure.

[0052] It should be noted that the support spring 3113 is stuck in the four-part groove 321, and its two ends are fixedly connected to the elastic head 3111 and the outer tube 31 respectively.

[0053] Through the above structure, the equipment wire clamp with an anti-breaking structure sets the secondary anti-breaking structure to be composed of a top block 323 on the inner cylinder 32 and a double-headed clamp body 311 on the outer cylinder 31, and an elastic head 3111 and a locking head 3112 are respectively arranged at both ends of the double-headed clamp body 311. Under normal conditions, the elastic head 3111 is pressed on the wire core 1 to provide support force. When the wire core 1 slides, the top block 323 pushes the locking head 3112 inward, so that the locking head 3112 clamps the wire core 1, thereby playing a secondary anti-breaking role. At the same time, the elastic head 3111 is separated from the wire core 1, so that the wire core 1 has a larger activity space, thereby preventing the wire core 1 from collapsing too tight and reducing the tension on the anti-breaking structure.

[0054] It is further provided that a four-part groove 321 is provided at the end of the inner tube 32 corresponding to the position of the double-headed clamp body 311, and the four-part groove 321 divides the end of the inner tube 32 into four separate four-part tubes 322. A top block 323 is provided at the bottom of the four-part groove 321. Four through holes 324 and four double-headed clamp bodies 311 are combined to seal one end of the outer tube 31 close to the wire core 1. An end cover 312 is provided at one end of the outer tube 31 close to the wire clamp body 2. The end cover 312 is connected and fixed to the outer tube 31 and the wire clamp body 2, so that the dust cover 3 remains sealed.

[0055] It should be noted that the quartered groove 321 may also be configured as a closed structure, that is, the space in the quartered groove 321 is not connected to the interior of the inner tube 32 .

[0056] The equipment wire clamp with an anti-breaking structure is provided with a four-part groove 321 at the position of the double-headed clamp body 311 at the end of the inner cylinder 32. The four-part groove 321 divides the inner cylinder 32 into four four-part cylinders 322. The four-part cylinders 322 and the double-headed clamp body 311 play the role of sealing the end of the outer cylinder 31. At the same time, an end cover 312 is provided at the other end to keep the dust cover 3 sealed under normal conditions, thereby achieving a waterproof and dustproof effect. The dust cover 3 wraps the part of the wire clamp body 2 that is connected to the wire core 1, thereby extending the service life of the wire clamp body 2.

[0057] It is further provided that a locking rod 327 is provided on the inner cylinder 32, the locking ring 4 includes an outer ring 41 and an inner ring 42 connected by threads, a plurality of elastic grooves 421 are provided at the end of the inner ring 42, a pressing sheet 422 is provided on the inner side of the end of the inner ring 42, a locking hole 411 is provided on the outer side of the outer ring 41, and the locking rod 327 is clamped in the locking hole 411 for connecting the locking ring 4 and the inner cylinder 32.

[0058] It should be noted that when the outer ring 41 is connected to the inner ring 42 by threads, the inner ring 42 is gradually pressed inwards by the elastic groove 421 , and the wire core 1 is clamped and fixed by the inner pressing sheet 422 .

[0059] Further, a slide groove 326 is provided on the inner cylinder 32, a slider 325 is slidably connected in the slide groove 326, the locking rod 327 is fixed on the inner side of the slider 325, a cylinder 328 is also fixed in the inner cylinder 32, and the push-pull rod end of the cylinder 328 is connected to the slider 325; A temperature sensor is arranged in the inner cylinder 32; A perforation 324 is provided on the side of the end of each quarter-tube 322, and fans are provided in the quarter-tubes 322 at two symmetrical positions. When the temperature sensor detects that the temperature is too high, the cylinder 328 pushes the slider 325 to make the inner tube 32 slide actively, and the fan in the quarter-tube 322 is started for heat dissipation. The four separately arranged quarter-tubes 322 have the air inlet and the air outlet spaced apart, which improves the fluidity of the air flow, and under normal circumstances, the perforation 324 is hidden in the outer tube 31 to prevent dust from entering.

[0060] Furthermore, each of the quarter-tubes 322 is provided with a warning light and an alarm on its side.

[0061] The equipment wire clamp with an anti-breaking structure can also be provided with a warning light, an alarm or a perforation 324 on the side of the quarter-tube 322. Under normal circumstances, these parts are hidden in the outer tube 31 and are only exposed to the outside when the inner tube 32 slides out, thereby improving the sealing effect under normal circumstances. In addition, a cylinder 328 can be further provided in the inner tube 32 to actively push the inner tube 32 to move, and a fault in the dust cover 3 is detected through a detection device, thereby actively cooling and alarming. At the same time, the four separate quarter-tubes 322 set the air inlet and the air outlet at intervals, thereby improving the gas flowability during heat dissipation.

[0062] It is further provided that a rubber layer is provided on the contact surface of the elastic head 3111 and the locking head 3112 with the wire core 1 .

[0063] It is further provided that a through slot 24 is provided at the bottom of the locking slot 23 , and the locking hole 411 passes through the through slot 24 .

[0064] It should be noted that the locking hole 411 may also be provided on the other side.
