Description

Technical Field

[0001] The present invention relates to the technical field of mating parts, and specifically to a device clamp with an anti-breaking structure. Background Art

[0002] In key fields such as power transmission, communication, and the connection of various industrial equipment, device clamps, as important components for realizing the reliable connection between conductors and electrical equipment, play an indispensable role. However, a series of problems that need to be solved urgently have emerged in the actual application of current device clamps on the market, among which the problem of easy fracture of the conductor is the most prominent.

[0003] During the long-term service of traditional device clamps, they need to continuously bear the combined action of various external forces such as the self-weight of the conductor, wind force, and thermal expansion and contraction. During this process, stress concentration is extremely likely to occur at the contact part between the clamp and the conductor. Over time, this stress concentration accumulates continuously, gradually weakening the structural strength of the conductor, and ultimately leading to the fracture of the conductor. This not only seriously threatens the stability and reliability of power transmission or signal transmission but may also trigger serious safety accidents, causing incalculable losses.

[0004] To solve the problem of conductor fracture, many explorations have been carried out in related technical fields. For example, a patent with the publication number CN111509480B discloses a device clamp anti-breaking device. When the cable of the device clamp is subjected to a swinging external force, the device restricts the movement range of the cable and absorbs the external force through a plurality of symmetrically arranged springs, thereby preventing the cable from breaking and also taking into account the problem of the disconnection between the conductor and the clamp. However, after in-depth analysis of the above patent and other existing technologies, many defects are still found.

[0005] First, the anti-breaking effect of the existing technology is poor, and the tensile value that can be borne during fracture is too low to meet the increasing high-intensity use requirements. Second, the triggering part of some anti-breaking structures is installed inside the clamp body. When the clamp becomes loose, it will have an adverse effect on triggering, reducing the effectiveness of the anti-breaking mechanism. Third, if the triggering part of the anti-breaking structure is set at a position outside the clamp body, it will affect the installation efficiency of the clamp, increasing the construction difficulty and time cost. Fourth, the clamps generally have poor dust and water protection effects, which makes it easy for external dust, moisture and other impurities to invade, further corroding the conductor and the clamp, accelerating their damage and reducing the service life.

[0006] In summary, there are many deficiencies in the anti-breaking technology of existing device clamps, which seriously restrict their efficient and stable application in various fields. Therefore, it is of great practical significance and application value to develop a new device clamp anti-breaking structure with excellent anti-breaking effect, reliable triggering mechanism, efficient installation method, and good dust and water protection performance. Summary of the Invention

[0007] (1) Technical problems to be solved

[0008] In view of the deficiencies of the prior art, the present invention provides a device wire clamp with an anti-break structure, which has the advantages of multiple anti-break structures, long service life, simple and convenient installation, and good waterproof and dustproof effects, and solves the problems of poor anti-break effect, too low tensile value that can be withstood when breaking occurs, short service life, low installation efficiency, and poor waterproof and dustproof effects in the prior art.

[0009] (2) Technical solutions

[0010] To achieve the above object, the present invention provides the following technical solutions:

[0011] A device wire clamp with an anti-break structure includes a wire clamp body. A wire groove for clamping a wire core is provided on the wire clamp body. Two arcuate pressing plates are further provided on the wire groove. A locking groove is provided at the position between the two arcuate pressing plates on the wire groove. A locking ring is detachably fixed on the wire core. The locking ring slides in the locking groove. The locking ring is limited by the limiting structure of the arcuate pressing plate to form a primary anti-break structure;

[0012] A dustproof cover is wrapped outside the wire clamp body. The dustproof cover includes an outer cylinder and an inner cylinder sleeved inside and outside. The inner cylinder is connected to the locking ring, and the locking ring drives the inner cylinder to slide. A secondary anti-break structure is further provided on the inner cylinder and the outer cylinder. When the inner cylinder and the outer cylinder slide relative to each other, the secondary anti-break structure clamps the wire core.

[0013] Preferably, four double-headed clamping bodies are provided on the circumference at one end of the outer cylinder close to the wire core. The middle part of the double-headed clamping body is rotatably connected to the outer cylinder. A locking head is provided at one end of the double-headed clamping body close to the wire clamp body;

[0014] A top block is provided on the inner cylinder. When the locking ring drives the inner cylinder to slide outwards, the top block pushes the locking head inwards, and the locking head clamps on the wire core to limit the sliding of the wire core;

[0015] The combination of the double-headed clamping body and the top block forms a secondary anti-break structure.

[0016] Preferably, an elastic head is provided at one end of the double-headed clamping body far from the wire clamp body. A support spring is further provided between the elastic head and the outer cylinder, which is used to fit the elastic head on the wire core. Under normal conditions, the elastic head provides an elastic supporting force for the wire core, reducing the risk of wire core breakage. When triggering the secondary anti-break structure to make the locking head clamp the wire core inwards, it drives the elastic head to rotate outwards away from the wire core, providing a larger movement space for the wire core and reducing the pressure on the anti-break structure.

[0017] Preferably, a quarter slot is provided at the position of the inner cylinder end corresponding to the double-headed clamp body. The quarter slot divides the inner cylinder end into four separate quarter cylinders. The top block is arranged at the bottom of the quarter slot. The four perforations and the four double-headed clamp bodies are combined to seal one end of the outer cylinder close to the wire core. One end of the outer cylinder close to the clamp body is provided with an end cover, and the end cover connects and fixes the outer cylinder and the clamp body, so as to keep the inside of the dust cover sealed.

[0018] Preferably, a locking rod is provided on the inner cylinder. The locking ring includes an outer ring and an inner ring connected by threads. A plurality of elastic slots are arranged at the end of the inner ring. A pressing piece is arranged on the inner side of the end of the inner ring. A locking hole is arranged on the outer side of the outer ring. The locking rod is stuck in the locking hole for connecting the locking ring and the inner cylinder.

[0019] Preferably, a sliding groove is provided on the inner cylinder. A slider is slidably connected in the sliding groove. The locking rod is fixed on the inner side of the slider. A cylinder is also fixed inside the inner cylinder. The end of the push-pull rod of the cylinder is connected to the slider.

[0020] A temperature sensor is arranged inside the inner cylinder.

[0021] Perforations are provided on the side surfaces of the ends of each quarter cylinder. Fans are arranged in two quarter cylinders at symmetrical positions. When the temperature sensor detects that the temperature is too high, the cylinder pushes the slider to make the inner cylinder slide actively, and the fans in the quarter cylinders are started for heat dissipation. The four separately arranged quarter cylinders make the air inlets and air outlets arranged at intervals, improving the air flow. And normally, the perforations are hidden inside the outer cylinder to prevent dust from entering.

[0022] Preferably, warning lights are also arranged on the sides of each quarter cylinder.

[0023] Preferably, the material of the inner cylinder is an insulating material, and the material of the outer cylinder is a metal material.

[0024] Preferably, rubber layers are arranged on the contact surfaces of the elastic head and the locking head with the wire core.

[0025] Preferably, a through slot is arranged at the bottom of the locking slot, and the locking hole passes through the through slot.

[0026] (III) Beneficial effects

[0027] Compared with the prior art, the present invention provides a device wire clamp with an anti-breaking structure, having the following beneficial effects:

[0028] 1. The equipment wire clamp with an anti-break structure has a locking ring set on the wire core. The locking ring slides within the locking groove between two bow-shaped pressing plates. The locking ring is not under stress under normal conditions. Only when the wire core slides, that is, when the connection of the wire clamp body becomes loose, the locking ring slides onto the rear bow-shaped pressing plate to act as a limiting structure, which is the first anti-break structure. After installing the locking ring on the wire core, the wire core can be fixed in the wire placement groove. The installation is simple and convenient, and the installation efficiency will not be affected by setting the anti-break structure.

[0029] 2. For the equipment wire clamp with an anti-break structure, the locking ring is connected to the inner cylinder. When the locking ring moves, it triggers a secondary anti-break structure composed of the inner cylinder and the outer cylinder. Since the locking ring is not under stress under normal conditions and has a long service life, the triggering of the secondary anti-break structure is stable and not prone to failure. At the same time, the dust-proof cover is set as a double-layer structure composed of the outer cylinder and the inner cylinder, improving the protection effect of the dust-proof cover.

[0030] 3. For the equipment wire clamp with an anti-break structure, the secondary anti-break structure is set to be composed of a top block on the inner cylinder and a double-headed clamping body on the outer cylinder. Elastic heads and locking heads are respectively set at both ends of the double-headed clamping body. Under normal conditions, the elastic head presses on the wire core to provide a supporting force. When the wire core slides, the top block pushes the locking head inward, making the locking head clamp the wire core to play a secondary anti-break role. At the same time, the elastic head disengages from the wire core, giving the wire core a larger movement space, avoiding the wire core being clamped too tightly and thus reducing the tension on the anti-break structure.

[0031] 4. For the equipment wire clamp with an anti-break structure, a quarter groove is set at the end of the inner cylinder corresponding to the double-headed clamping body. The quarter groove divides the inner cylinder into four quarter cylinders. The quarter cylinders and the double-headed clamping body play a role in sealing the end of the outer cylinder. At the same time, an end cover is set at the other end to keep the inside of the dust-proof cover sealed under normal conditions, achieving a waterproof and dust-proof effect. The dust-proof cover wraps the part of the wire clamp body connected to the wire core, extending the service life of the wire clamp body.

[0032] 5. For the equipment wire clamp with an anti-break structure, warning lights, alarms or perforations can also be set on the side of the quarter cylinder. Under normal conditions, these parts are all hidden inside the outer cylinder and are only exposed when the inner cylinder slides out, improving the sealing effect under normal conditions. And a cylinder can be set inside the inner cylinder to actively push the inner cylinder to move. When a failure occurs inside the dust-proof cover is detected by the detection device, it can actively cool down and give an alarm. At the same time, the four separate quarter cylinders set the air inlet and the air outlet at intervals, improving the gas flow during heat dissipation. BRIEF DESCRIPTION OF THE DRAWINGS

Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present invention, "a plurality of" means two or more unless otherwise specifically defined.

[0054] Embodiment 1:

[0055] This embodiment provides a device clamp with an anti-breaking structure, having the following technical features.

[0056] Please refer to Figures 1-13 , a device clamp with an anti-breaking structure, including a clamp body 2. A wire groove 21 for clamping a wire core 1 is provided on the clamp body 2. Two arc-shaped pressing plates 22 are further provided on the wire groove 21. A locking groove 23 is provided at the position of the wire groove 21 between the two arc-shaped 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. The locking ring 4 is limited by the limiting structure of the arc-shaped pressing plate 22 to form a primary anti-breaking structure;

[0057] The outside of the clamp body 2 is wrapped with a dust-proof cover 3. The dust-proof cover 3 includes an outer cylinder 31 and an inner cylinder 32 which are sleeved inside and outside. The inner cylinder 32 is connected to a locking ring 4, and the locking ring 4 drives the inner cylinder 32 to slide. A secondary anti-breaking structure is also provided on the inner cylinder 32 and the outer cylinder 31. When the inner cylinder 32 and the outer cylinder 31 slide relative to each other, the secondary anti-breaking structure clamps the wire core 1.

[0058] Furthermore, the material of the inner cylinder 32 is an insulating material, and the material of the outer cylinder 31 is a metal material.

[0059] It should be noted that the material of the inner cylinder 32 is mica board, which is made of mica flakes or ground mica, adhesives, and reinforcing materials. The material of the outer cylinder 31 is aluminum alloy, which has good compressive, tensile, and impact resistance. It can effectively protect the internal insulating layer and the clamp from external damage, has good corrosion resistance, and is easy to form a dense oxide film on the surface, which can prevent corrosion by rainwater, air, etc., extend the service life, and is light in weight. Compared with other metal materials, aluminum alloy is lighter in weight, which is convenient for installation and maintenance, reduces the construction difficulty and cost.

[0060] By setting the above structure, for the equipment clamp with an anti-breaking structure, a locking ring 4 is arranged on the wire core 1. The locking ring 4 slides in the locking groove 23 between two bow-shaped pressing plates 22. The locking ring 4 is not stressed under normal conditions. Only when the wire core 1 slides, that is, when the connection of the clamp body 2 becomes loose, the locking ring 4 slides onto the rear bow-shaped pressing plate 22 to play a limiting structure, that is, the first anti-breaking structure. Only need to install the locking ring 4 on the wire core 1 and then fix the wire core 1 in the wire placement groove 21. The installation is simple and convenient, and the installation efficiency will not be affected by setting the anti-breaking structure.

[0061] Moreover, the locking ring 4 is connected to the inner cylinder 32. When the locking ring 4 moves, it triggers the secondary anti-breaking structure composed of the inner cylinder 32 and the outer cylinder 31. Since the locking ring 4 is not stressed 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-proof cover 3 is set as a double-layer structure composed of the outer cylinder 31 and the inner cylinder 32, which improves the protection effect of the dust-proof cover 3.

[0062] Furthermore, four double-headed clamping bodies 311 are arranged on the circumference of one end of the outer cylinder 31 close to the wire core 1. The middle part of the double-headed clamping body 311 is rotatably connected to the outer cylinder 31, and a locking head 3112 is arranged at one end of the double-headed clamping body 311 close to the clamp body 2.

[0063] A top block 323 is arranged on the inner cylinder 32. When the locking ring 4 drives the inner cylinder 32 to slide outwards, the top block 323 pushes the locking head 3112 inwards, and the locking head 3112 clamps on the wire core 1 to limit the sliding of the wire core 1.

[0064] The combination of the double-headed clamping body 311 and the top block 323 forms a secondary anti-breaking structure.

[0065] 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.

[0066] 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.

[0067] 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.

[0068] 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.

[0069] 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.

[0070] 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 .

[0071] The device wire clamp with an anti-breaking structure is provided with a quarter groove 321 at the end of the inner cylinder 32 corresponding to the position of the double-headed clamp body 311. The quarter groove 321 divides the inner cylinder 32 into four quarter cylinders 322. The quarter cylinders 322 and the double-headed clamp body 311 play a role in 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, achieving the effects of waterproofing and dustproofing. The dust cover 3 wraps the part of the wire clamp body 2 connected to the wire core 1, extending the service life of the wire clamp body 2.

[0072] Furthermore, 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 piece 422 is provided inside the end of the inner ring 42. A locking hole 411 is provided on the outer side of the outer ring 41. The locking rod 327 is stuck in the locking hole 411 for connecting the locking ring 4 and the inner cylinder 32.

[0073] It should be noted that when the outer ring 41 is connected to the inner ring 42 by threads, under the action of the elastic grooves 421, the inner ring 42 is gradually squeezed inward, and the wire core 1 is clamped and fixed by the inner pressing piece 422.

[0074] Furthermore, a sliding groove 326 is provided on the inner cylinder 32. A slider 325 is slidably connected in the sliding groove 326. The locking rod 327 is fixed inside the slider 325. A cylinder 328 is also fixed inside the inner cylinder 32. The end of the push-pull rod of the cylinder 328 is connected to the slider 325.

[0075] A temperature sensor is provided inside the inner cylinder 32.

[0076] Perforations 324 are provided on the side of the end of each quarter cylinder 322. Fans are provided in two symmetrically positioned quarter cylinders 322. When the temperature sensor detects that the temperature is too high, the cylinder 328 pushes the slider 325, causing the inner cylinder 32 to slide actively, and starting the fans in the quarter cylinders 322 for heat dissipation. The four separately provided quarter cylinders 322 set the air inlet and outlet at intervals, improving the air flow, and the perforations 324 are hidden inside the outer cylinder 31 under normal conditions, preventing dust from entering.

[0077] Furthermore, warning lights and alarms are also provided on the side of each quarter cylinder 322.

[0078] The device clamp with an anti-breaking structure can also be provided with warning lights, alarms or perforations 324 on the side of the quarter cylinder 322. Under normal conditions, these parts are hidden inside the outer cylinder 31 and are only exposed when the inner cylinder 32 slides out, improving the sealing effect under normal conditions. Also, a cylinder 328 can be arranged inside the inner cylinder 32 to actively push the inner cylinder 32 to move. When a malfunction occurs inside the dust cover 3 detected by the detection device, it can actively cool down and give an alarm. At the same time, the four separate quarter cylinders 322 arrange the air inlets and outlets at intervals, improving the gas flow during heat dissipation.

[0079] Furthermore, rubber layers are provided on the contact surfaces of the elastic head 3111 and the locking head 3112 with the wire core 1.

[0080] Furthermore, a through slot 24 is provided at the bottom of the locking slot 23, and the lock hole 411 passes through the through slot 24.

[0081] It should be noted that the lock hole 411 can also be arranged on the other side.

[0082] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprising", "including" or any other variant thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device. Without further limitation, an element defined by the statement "including a..." does not exclude the existence of additional identical elements in the process, method, article or device including the said element.

[0083] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.

When the secondary anti-breaking structure is triggered to cause the locking head (3112) to clamp the wire core (1) inwardly, the elastic head (3111) is driven to rotate outwardly and detach from the wire core (1), thereby providing a larger activity space for the wire core (1) and reducing the pressure on the anti-breaking structure.

3. The equipment wire clamp with an anti-breaking structure according to claim 2, characterized in that: A four-part groove (321) is provided at the end of the inner tube (32) at a position corresponding to the double-headed clamp body (311); 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 an end of the outer tube (31) close to the wire core (1); an end cover (312) is provided at an end of the outer tube (31) close to the wire clamp body (2); the end cover (312) connects and fixes the outer tube (31) and the wire clamp body (2), thereby maintaining a sealed interior of the dust cover (3).

4. The equipment wire clamp with an anti-breaking structure according to claim 3, characterized in that: A locking rod (327) is provided on the inner cylinder (32); the locking ring (4) comprises 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); the locking rod (327) is clamped in the locking hole (411) and is used to connect the locking ring (4) and the inner cylinder (32).

5. The equipment wire clamp with an anti-breaking structure according to claim 4, characterized in that: The inner cylinder (32) is provided with a slide groove (326), 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), and 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 surface 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 actively slide the inner tube (32), and the fan in the quarter-tube (322) is started to dissipate heat. The four separately arranged quarter-tubes (322) have air inlets and air outlets arranged at intervals, thereby improving the fluidity of the air flow, and the perforations (324) are normally hidden in the outer tube (31), thereby preventing dust from entering.
