Description

Technical Field

[0001] The present invention relates to the technical field of wire and cable fixing, and particularly to an insulating fixing device for wire and cable struts. Background Art

[0002] An insulator is a device installed between conductors at different potentials or between a conductor and a grounding member, which can withstand voltage and mechanical stress; there are various types of insulators with different shapes; although the structures and outer shapes of different types of insulators vary greatly, they are all composed of two major parts: an insulating part and a connecting fitting; an insulator is a special insulating control device and can play an important role in overhead power transmission and distribution lines.

[0003] For the wires fixed on insulators, they are usually manually wound and tied by operators. The tying materials for aluminum stranded wires and steel core stranded wires are the same as the wire materials. Aluminum tying wires are used for aluminum magnesium alloy wires, and iron tying wires with outer skins are used for insulated wires. However, in actual use, this fixing method is cumbersome and inconvenient, and the structural strength after fixing is affected by time. The tying materials exposed outdoors for a long time will be eroded by the external environment, so there is a risk of breakage after long-term use, and it is greatly affected by individual factors of construction workers. There are problems such as inconsistent tying wire processes, and the number of turns of wire winding and the tightness of wire fixing cannot be completely unified. Summary of the Invention

[0004] The present invention discloses an insulating fixing device for wire and cable struts, aiming to solve the technical problems that the existing methods and ways of fixing insulators are cumbersome and inconvenient in actual operation and the firmness strength after fixing needs to be improved.

[0005] To achieve the above object, the present invention adopts the following technical solutions: An insulating fixing device for wire and cable struts includes a kit. An insulator is snap-fitted at the inner bottom of the kit. A wire and cable is snap-fitted in the wire groove at the top of the insulator. A longitudinal fixing mechanism for squeezing and fixing the wire and cable and the insulator is arranged inside the kit. The longitudinal fixing mechanism includes a rod vertically penetrating through the top of the kit. Brake members are distributed at the bottom of the rod, and the brake members squeeze and contact the top of the wire and cable. A transverse fixing mechanism for enclosing the insulator is snap-fitted on the side of the kit. The transverse fixing mechanism includes a sealing plate snap-fitted at the end of the kit. An extrusion mechanism for squeezing and fixing the insulator is arranged inside the transverse fixing mechanism. The extrusion mechanism includes extrusion members symmetrically arranged on both sides of one end of the brake member. Moving members are slidably installed on both sides inside the sealing plate, and the extrusion members squeeze and contact the top of the moving members. A locking assembly is further arranged on the side of the sealing plate, and the locking assembly is used for laterally clamping the wire and cable. The insulator is hermetically fixed by the cooperation of the horizontal fixing mechanism and the kit. Meanwhile, along with the extrusion of the top of the cable by the vertical fixing mechanism, the extrusion mechanism can synchronously extrude and fix the insulator.

[0006] The side of the kit is provided with a horizontal fixing mechanism for blocking the side of the kit and extruding and fixing the top of the insulator. While the horizontal fixing mechanism cooperates with the kit to hermetically fix the insulator, along with the extrusion of the top of the cable by the vertical fixing mechanism, the extrusion mechanism can synchronously extrude and fix the insulator, and the cable can be clamped by matching with the locking component, so as to achieve the fixing effect in multiple directions and multiple ways and ensure the stability of the insulator and the cable.

[0007] In a preferred solution, the vertical fixing mechanism further includes a threaded sleeve rotatably installed outside the rod. The threaded sleeve is threadedly connected to the kit. A slot is provided at the top of the brake part, and a pin is provided at the bottom of the rod. The pin is misaligned and engaged into the inside of the slot to form a connection to the brake part.

[0008] By arranging a rod structure connected by a threaded sleeve at the top of the kit, the threaded sleeve is used to drive the rod to move vertically, so that the brake part at the bottom of the rod extrudes and contacts the top of the insulator, thereby initially fixing the insulator and maintaining the structural stability of the insulator.

[0009] In a preferred solution, the horizontal fixing mechanism further includes buckles arranged on both sides of the end of the kit. A card slot is penetrated and opened inside the sealing plate. The buckles are engaged into the inside of the card slot. A cross slot is opened at the end of the buckle, and an inclined surface is arranged at the edge of the end of the buckle.

[0010] By additionally arranging a sealing plate with a self - contained card slot structure on the side of the kit, after the insulator is installed inside the kit, the sealing plate is fixed to the side of the kit by the mutual cooperation of the card slot and the buckle, thereby preventing the fixed insulator from slipping off the side and improving the fixing efficiency of the insulator.

[0011] In a preferred solution, the extrusion mechanism further includes a first stop pin fixedly installed on the side of the moving part. Second stop pins are symmetrically arranged on both sides of the top of the sealing plate. Each second stop pin and a first stop pin are symmetrically distributed in the vertical direction and form an extrusion contact with the top of the insulator. A locking component is further arranged on the side of the sealing plate, and the locking component is in extrusion contact with the cable.

[0012] By additionally providing a first stop pin structure connected to the moving member inside the plugging plate, as the plugging plate and the kit are engaged, the first stop pin and the second stop pin on the side of the plugging plate will be engaged into the inside of the kit together. And with the downward pressure of the braking member, the moving member moving synchronously will drive the first stop pin together, causing relative movement between the first stop pin and the second stop pin, thereby squeezing the top of the insulator and improving the structural stability of the insulator.

[0013] In a preferred embodiment, the locking assembly includes a locking plate slidably distributed inside the plugging plate. An inclined driving groove is formed inside the locking plate. A driving member is fixed on the side of the moving member, and the driving member is slidably distributed inside the driving groove.

[0014] By providing a locking plate structure driven by the driving groove, with the vertical movement of the moving member, during the movement, it will squeeze the driving groove through the driving member together, thereby causing the locking plate normally received inside the plugging plate to move synchronously and press on the cable, thereby improving the overall structural stability.

[0015] In a preferred embodiment, the extrusion end of the locking plate and the cable is provided with an arc-shaped structure, and a gasket is adhered inside the arc-shaped structure.

[0016] By setting the end of the locking plate as an arc-shaped structure, and a gasket is adhered inside the arc-shaped structure, the arc-shaped structure enables the locking plate to better fit the cable.

[0017] In a preferred embodiment, ears are provided on the outside of the buckle, and ear chambers are provided on the outside of the card slot, and the ears are engaged into the inside of the ear chambers.

[0018] When the plugging plate is engaged outside the kit, the additional ears and ear chambers are engaged with each other, thereby further improving the structural stability after the installation of the plugging plate.

[0019] In a preferred embodiment, an inner arc portion is provided at the bottom of the kit, and an arc-shaped member is provided on the side of the plugging plate. The inner arc portion and the arc-shaped member form a closed circular structure and are engaged and fixed outside the insulator.

[0020] By additionally providing an arc-shaped member on the side of the plugging plate, using the arc-shaped member and the inner arc portion to form a closed circular structure, thereby being engaged and fixed outside the insulator to improve the stability after the installation of the insulator.

[0021] As can be seen from the above, a wire and cable support insulating fixing device provided by the present invention has the following technical effects.

[0022] First: By setting a kit and a longitudinal fixing mechanism, the cable is fixed to the top of the insulator. The top of the kit is provided with a pole structure connected by a threaded sleeve. The threaded sleeve drives the pole to move vertically, so that the brake part at the bottom of the pole presses against the top of the cable, thereby fixing the cable to the top of the insulator. The insulator is fixed inside the kit, realizing the quick installation and fixation of the cable and the insulator, solving the uncertainty of manual wiring, effectively avoiding the detachment between the insulator and the cable, and ensuring the safe operation of the power grid.

[0023] Second: By additionally providing a sealing plate structure with a self - contained slot structure on the side of the kit, after the insulator is installed inside the kit, the sealing plate is fixed to the side of the kit by the mutual cooperation of the slot and the buckle, thereby preventing the fixed insulator from slipping off laterally, and improving the fixing efficiency and stability of the insulator horizontally.

[0024] Third: By additionally providing a first stop pin structure connected to a moving part inside the sealing plate, with the clamping of the sealing plate and the kit, the first stop pin and the second stop pin on the side of the sealing plate will be clamped into the kit together. And with the downward pressure of the brake part, the moving part moving synchronously will drive the first stop pin together, causing the first stop pin and the second stop pin to move relatively, thereby forming an extrusion fixation on the insulator from inside the kit, and further improving the stability of the insulator structure.

[0025] Fourth: The moving part is additionally associated with a locking plate structure. By setting a locking plate driven by a driving groove to move vertically with the moving part, during the movement, it will press against the driving groove through a driving part together, so that the locking plate normally stored inside the sealing plate moves synchronously and presses against the cable, thereby greatly improving the overall structural stability.

Detailed implementation manners

[0038] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0039] An insulating fixing device for an electric wire and cable support pillar disclosed by the present invention is mainly applied to the scenario of quickly installing an insulator.

[0040] Referring to Figures 1 to 11 , an insulating fixing device for an electric wire and cable support pillar includes a kit 2. An insulator is clamped at the inner bottom of the kit 2, and a cable 1 is clamped in the wire groove at the top of the insulator. A longitudinal fixing mechanism 3 for squeezing and fixing the cable 1 and the insulator is arranged inside the kit 2. The longitudinal fixing mechanism 3 includes a support rod 301 vertically penetrating through the top of the kit 2, and brake parts 303 are distributed at the bottom of the support rod 301. The brake parts 303 are in pressing contact with the top of the cable 1; A transverse fixing mechanism 4 for closing the insulator is clamped on the side of the kit 2. The transverse fixing mechanism 4 includes a plugging plate 402 clamped at the end of the kit 2; Inside the horizontal fixing mechanism 4, there is an extrusion mechanism 5 for extruding and fixing the insulator. The extrusion mechanism 5 includes extrusion members 501 symmetrically arranged on both sides of one end of the brake member 303. On both sides inside the sealing plate 402, moving members 502 are slidably installed, and the extrusion members 501 are in extrusion contact with the tops of the moving members 502. The insulator is hermetically fixed by the cooperation of the horizontal fixing mechanism 4 and the kit 2. At the same time, along with the extrusion of the top of the cable 1 by the vertical fixing mechanism 3, the cable 1 is fixed to the insulator without manual binding, and the extrusion mechanism 5 can perform synchronous extrusion and fixing on the insulator.

[0041] In this embodiment: The operator holds the insulator and inserts it into the kit 2. At the same time, the cable 1 is placed in the wire groove on the top of the insulator. Then, the operator snaps a horizontal fixing mechanism 4 into the end of the kit 2, thereby forming an occlusion and fixation on the side of the kit 2. Then, the vertical fixing mechanism 3 is rotated, causing the vertical fixing mechanism 3 to move vertically along the inside of the kit 2 and be in extrusion contact with the top of the insulator, thereby performing vertical pressing and fixing on the insulator and the cable 1. When the vertical fixing mechanism 3 moves vertically, it will simultaneously exert synchronous extrusion on the extrusion mechanism 5, causing the extrusion mechanism 5 to operate, improving the connection strength between the horizontal fixing mechanism 4 and the kit 2, and at the same time improving the stability of the insulator and the cable 1.

[0042] Refer to Figures 1 to 5 、 Figure 9 In a preferred embodiment, the vertical fixing mechanism 3 further includes a threaded sleeve 302 rotatably installed on the outside of the support rod 301. The threaded sleeve 302 is threadedly connected to the kit 2. A slot 305 is provided at the top of the brake member 303, and a pin 304 is provided at the bottom of the support rod 301. The pin 304 is misaligned and snapped into the inside of the slot 305 to form a connection with the brake member 303.

[0043] In the non-operating state, as the operator continuously rotates the threaded sleeve 302, the threaded sleeve 302 and the support rod 301 will move downward (at this time, the support rod 301 will not rotate), and the brake member 303 at the bottom of the support rod 301 will be removed from the bottom of the kit 2. At this time, the operator manually rotates the brake member 303 until the pin 304 and the notch of the slot 305 are aligned. At this time, the operator can remove the current brake member 303 from the bottom of the support rod 301 and replace it with a brake member 303 of other sizes according to the shape and size of the insulator.

[0044] Refer to Figures 1 to 7 In a preferred embodiment, the horizontal fixing mechanism 4 further includes buckles 401 provided on both sides of the end of the kit 2. A card slot 403 is formed through the inside of the sealing plate 402, and the buckles 401 are snapped into the inside of the card slot 403.

[0045] Specifically, the operator aligns the card slot 403 on the side of a plugging plate 402 with the buckle 401 on the side of the kit 2 and pushes forcefully, causing the buckle 401 to snap into the inside of the card slot 403. At this time, the plugging plate 402 will be snapped together at the end of the kit 2, thereby forming an occlusion and fixation on the side of the kit 2. Among them, an ear piece 4011 is arranged on the outer side of the buckle 401, and an ear chamber 4031 is arranged on the outer side of the card slot 403. The ear piece 4011 snaps into the inside of the ear chamber 4031. Under microscopic conditions, when the braking member 303 longitudinally squeezes the insulator, it will cause the insulator to produce a microscopic deformation outward, and the kit 2 will also produce a microscopic deformation. Since the ear piece 4011 and the ear chamber 4031 are matched in size and snap together, the two can constrain each other, thereby further improving the stability of the kit 2 and the plugging plate 402 during operation.

[0046] Specifically, as Figure 10 shown, a cross slot 4012 is opened at the end of the buckle 401, and an inclined surface 4013 is arranged at the edge of the end of the buckle 401. In the initial state, the outer opening size of the end of the buckle 401 is larger than the inner opening size of the card slot 403. During the process of the buckle 401 being snapped into the card slot 403, the inclined surface 4013 of the buckle 401 will be stressed and cause the cross slot 4012 to close. After closing, the outer opening size of the buckle 401 decreases until the buckle 401 extends out of the card slot 403 and resets (as Figure 11 shown). The reset buckle 401 can prevent the plugging plate 402 from detaching from it. The material of the buckle 401 can be selected as an elastic metal material such as stainless steel, which has corrosion resistance and certain deformation characteristics at the same time. If it is necessary to disassemble the plugging plate 402, just squeeze the buckle 401 centrally with your finger.

[0047] Furthermore, an inner arc portion 201 is arranged at the bottom of the kit 2, and an arc surface member 404 is arranged on the side of the plugging plate 402. When the plugging plate 402 is snapped onto the side of the kit 2, at this time, the inner arc portion 201 and the arc surface member 404 will form a closed circular structure and be snapped and fixed on the outer side of the insulator, thereby ensuring the stability of the insulator after installation.

[0048] Referring to Figure 1 、 Figures 4 to 8 , in a preferred embodiment, the pressing mechanism 5 further includes a first stop pin 503 fixedly installed on the side of the moving member 502. Second stop pins 504 are symmetrically arranged on both sides of the top of the plugging plate 402. Each second stop pin 504 and a first stop pin 503 are symmetrically distributed in the vertical direction and form a pressing contact with the top of the insulator. A locking assembly 505 is further arranged on the side of the plugging plate 402, and the locking assembly 505 is in pressing contact with the cable 1.

[0049] When the operator snaps the sealing plate 402 into the end of the kit 2, the first stop pin 503 and the second stop pin 504 on the side of the sealing plate 402 will move synchronously and snap into the interior of the kit 2. The second stop pin 504 will press against the inner top of the kit 2 to form a fixation. When the brake member 303 moves vertically downward, it will drive the extrusion member 501 on the side to move synchronously downward. The moving extrusion member 501 will synchronously extrude the moving member 502, causing the moving member 502 to move vertically downward along the interior of the sealing plate 402. During the downward movement, it will drive the first stop pin 503 to move synchronously, thereby squeezing the top of the insulator and improving the stability of the insulator. Among them, a spring 506 is fixedly installed at the bottom of the moving member 502. The spring 506 is distributed inside the sealing plate 402. When the moving member 502 loses the restriction of the extrusion force, it will be pushed by the spring 506 and reset to move.

[0050] Further, the locking assembly 505 includes a locking plate 5051 slidably distributed inside the sealing plate 402. A driving groove 5052 is inclinedly formed inside the locking plate 5051. A driving member 5053 is fixed on the side of the moving member 502. The driving member 5053 is slidably distributed inside the driving groove 5052. When the moving member 502 moves vertically downward, it will drive the driving member 5053 to move downward together. The moving driving member 5053 will squeeze inside the driving groove 5052, causing the locking plate 5051 to be pressed and move horizontally, thereby squeezing and contacting the outside of the cable 1 to form a firm clamping of the whole. The extrusion ends of the locking plate 5051 and the cable 1 are set as arc-shaped structures. At the same time, a gasket 5054 is adhered inside the arc-shaped structure. The squeezed gasket 5054 will undergo elastic deformation to adapt to the moving stroke of the locking plate 5051 and the first stop pin 503. Among them, a transverse groove 507 is horizontally formed inside the sealing plate 402. The locking plate 5051 is slidably distributed inside the transverse groove 507.

[0051] It should be supplemented that when the extrusion member 501 extrudes the moving member 502, it will apply a downward pressure to the sealing plate 402 and can improve the tightness between the ear part 4011 and the ear chamber 4031, further enhancing the installation stability of the sealing plate 402.

[0052] Further, as Figure 1 shown, one side of the kit 2 close to the extrusion member 501 is a through surface. The end of the insulator can be snapped into the kit 2 from the through surface position, while the other side is a stop surface and the insulator cannot be snapped in. Through this design, it can be quickly judged whether the model size of the insulator is suitable for this device.

[0053] The working process of this application is as follows: First, as Figure 4 and Figure 5As shown, the operator holds the insulator and places its end on the surface of the inner arc portion 201 in the kit 2. The surface of the inner arc portion 201 is designed to be sunken, which can wrap the lower edge position of the end of the insulator. Moreover, a rubber pad is provided on the surface of the inner arc portion 201 to improve the stability after the insulator is placed. At the same time, the cable 1 is placed in the wire groove on the top of the insulator. Then, the operator aligns the card slot 403 on the side of a plugging plate 402 with the buckle 401 on the side of the kit 2 and pushes forcefully, causing the buckle 401 to snap into the inside of the card slot 403. At this time, the plugging plate 402 will be snapped together at the end of the kit 2, thereby forming an occlusion and fixation on the side of the kit 2. While the plugging plate 402 is snapped into the inside of the kit 2, the first stop pin 503 and the second stop pin 504 on the side of the plugging plate 402 will move synchronously and snap into the inside of the kit 2. The second stop pin 504 will be pressurized and fit against the inner top of the kit 2, thereby forming a fixation. After that, the worker screws the threaded sleeve 302, causing the threaded sleeve 302 to drive the rod 301 to move vertically along the inside of the kit 2, resulting in the synchronous movement of the brake member 303 at the bottom of the rod 301 and its extrusion contact with the top of the insulator, thereby longitudinally pressing and fixing the insulator and the cable 1; While the brake member 303 moves vertically downward, it will drive the extrusion member 501 on the side to move synchronously downward. The moving extrusion member 501 will synchronously extrude the moving member 502, causing the moving member 502 to move vertically downward along the inside of the plugging plate 402. During the downward movement, it will drive the first stop pin 503 to move synchronously, thereby forming an extrusion on the top of the insulator and improving the stability of the insulator; While the moving member 502 moves vertically downward, it will drive the driving member 5053 to move downward together. The moving driving member 5053 will be extruded into the inside of the driving groove 5052, causing the locking plate 5051 to be pressurized and move horizontally, thereby causing the gasket 5054 at the end of the locking plate 5051 to be extruded and contact the outside of the cable 1, forming a firm clamping on the whole and completing the fixed installation of the insulator and the cable 1.

[0054] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
