Description
Technical Field
[0001] This invention relates to the technical field of basalt fiber composite energy meter boxes with wiring positioning mechanisms, specifically a basalt fiber composite energy meter box with a precise wiring positioning mechanism. Background Technology
[0002] Basalt fiber composite electricity meter boxes are electricity metering equipment enclosures made of basalt fiber as the main reinforcing material, combined with unsaturated resin, low-shrinkage additives, fillers, and other composite materials, manufactured through processes such as compression molding. They are a type of composite meter box specifically designed for installing and protecting electricity meters and related electrical wiring components.
[0003] In existing technology, electricity meters measure electricity consumption by measuring current and voltage. Before measuring electricity consumption, wires need to be installed inside the meter. Since multiple meters are installed inside the meter box, in order to facilitate the maintenance or replacement of the wires inside the meters, workers will install multiple wires inside multiple meters at the same time. This allows for better recording of the wire usage time. However, during the installation process, most of the wires are installed one by one inside the meter using bolts. Due to the large number of meters, the wire installation process is quite cumbersome, thus reducing installation efficiency. Summary of the Invention
[0004] The purpose of this invention is to provide a basalt fiber composite energy meter box with a precise wiring positioning mechanism to solve the problems mentioned in the background art.
[0005] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution: This invention relates to a basalt fiber composite energy meter box with a precise wiring positioning mechanism, comprising a basalt fiber composite box, mounting rings fixedly connected to both sides of the basalt fiber composite box, a sealing door hinged to the surface of the basalt fiber composite box, a handle fixedly connected to the surface of the sealing door, and an energy meter fixedly connected to the inner wall of the basalt fiber composite box, and further comprising; A positioning mechanism, comprising a grooved plate, a sliding plate slidably connected to the inner wall of the grooved plate, and a positioning ring fixedly connected to the surface of the sliding plate; The self-locking mechanism includes a reset elastic rod, a self-locking ring fixedly connected to the end of the reset elastic rod, and a pull rod fixedly connected to the surface of the self-locking ring; A separation mechanism, comprising an elastic plate, wherein a separation ring is fixedly connected to the surface of the elastic plate.
[0006] Furthermore, the surface of the mounting ring is provided with mounting holes, and there are two sealing doors symmetrically arranged on the surface of the basalt fiber composite electrical box. The bottom of the meter is provided with wiring holes, and the inner wall of the basalt fiber composite electrical box is provided with a moving groove.
[0007] Furthermore, the positioning mechanism includes a slide plate, a bent rod is fixedly connected to the surface of the slide plate, a slide rod is fixedly connected to the end of the bent rod, a return spring is fixedly connected to the surface of the slide rod, and a push rod is hinged to the end of the positioning ring.
[0008] Furthermore, the surface of the slide plate is slidably connected to the inner wall of the wiring hole, the end of the push rod away from the positioning ring is hinged to the inner wall of the bent rod, the end of the return spring away from the bent rod is fixedly connected to the bottom of the meter, the surface of the slide rod is slidably connected to the inner wall of the moving groove, and the surface of the groove plate is fixedly connected to the inner wall of the basalt fiber composite electrical box.
[0009] Furthermore, the self-locking mechanism includes a support plate, a self-locking column is fixedly connected to the top of the support plate, a support ring is fixedly connected to the inner wall of the basalt fiber composite electrical box, U-shaped plates are fixedly connected to both sides of the support ring, a push plate is hinged to the end of the pull rod away from the self-locking ring, and a driven telescopic rod is fixedly connected to the bottom of the push plate.
[0010] Furthermore, the bottom of the support plate is fixedly connected to the surface of the return spring, the surface of the self-locking column is provided with a self-locking groove, the end of the return elastic rod away from the self-locking ring is fixedly connected to the inner wall of the U-shaped plate, the end of the driven telescopic rod away from the pressing plate is fixedly connected to the end of the support ring, and the inner wall of the self-locking ring is adapted to the inner wall of the self-locking groove.
[0011] Furthermore, the separation mechanism includes a right-angle plate, with a connecting plate fixedly connected to one end of the right-angle plate, and bidirectional telescopic plates fixedly connected to both ends of the connecting plate.
[0012] Furthermore, the end of the right-angle plate away from the connecting plate is fixedly connected to the bottom of the slide rod, and both ends of the elastic plate are fixedly connected to the surface of the bidirectional telescopic plate. The number of right-angle plates is set to six, and the six right-angle plates are symmetrically arranged on the surface of the slide rod.
[0013] The present invention has the following beneficial effects: This invention employs a positioning mechanism. When the bent rod moves, it pushes the sliding rod along the inner wall of the moving groove towards the top of the inner wall of the basalt fiber composite electrical box. Simultaneously, it pushes the return spring to retract towards the meter. As the bent rod moves, it also pushes the end of the push rod towards the meter, while the other end of the meter pushes the positioning ring towards itself. During this movement, the positioning ring contacts the wire, thus positioning it. Simultaneously, the positioning ring moves the sliding plate along the inner wall of the grooved plate towards itself. This efficient and rapid positioning of the wire eliminates the need for cumbersome bolt installation. Furthermore, multiple wires can be installed inside the meter, improving installation efficiency.
[0014] This invention employs a self-locking mechanism. When the self-locking groove moves to the center of the self-locking ring, the self-locking pin no longer presses against the self-locking ring. The self-locking ring, then, is pushed closer together by the elasticity of the reset elastic rod, causing its inner wall to contact the inner wall of the self-locking groove, thus completing the self-locking. When the wire needs to be disassembled, the operator simply presses the button and moves it towards the support ring, while simultaneously pushing the driven telescopic rod to retract towards the support ring. The button's movement pushes the end of the pull rod towards the self-locking ring, which in turn pushes the self-locking ring away from each other. This movement further pushes the reset elastic rod away from each other, separating the self-locking ring from the inner wall of the self-locking groove, thus resetting the positioning mechanism and allowing the wire to be removed. Effectively, the cooperation between the self-locking ring, pull rod, and button locks and secures the wire, while also enabling rapid disassembly, improving the efficiency of wire removal.
[0015] This invention employs a separation mechanism. As the sliding rod moves, it causes right-angle plates to move closer together. This movement pushes connecting plates closer together, and the connecting plates retract bidirectional telescopic plates. The retraction of the bidirectional telescopic plates causes the ends of elastic plates to move closer together. During this movement, the middle section of the elastic plate bends, pushing a separation ring closer together. This separation ring then contacts the surface of the wire, securing it. Simultaneously, the separation mechanism resets along with the positioning mechanism, facilitating rapid wire disassembly. With three sets of elastic plates, three wires can be secured, effectively reinforcing and separating them, improving the efficiency of wire sorting and preventing tangling.
[0016] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0021] Please see Figures 1-9 As shown, the present invention is a basalt fiber composite energy meter box with a precise wiring positioning mechanism, including a basalt fiber composite box 1, mounting rings 2 fixedly connected to both sides of the basalt fiber composite box 1, a sealing door 3 hinged to the surface of the basalt fiber composite box 1, a handle 4 fixedly connected to the surface of the sealing door 3, and an electricity meter 5 fixedly connected to the inner wall of the basalt fiber composite box 1, and also includes; The positioning mechanism 10 includes a grooved plate 15, a sliding plate 16 is slidably connected to the inner wall of the grooved plate 15, and a positioning ring 17 is fixedly connected to the surface of the sliding plate 16. The self-locking mechanism 30 includes a reset elastic rod 35, a self-locking ring 36 fixedly connected to the end of the reset elastic rod 35, and a pull rod 37 fixedly connected to the surface of the self-locking ring 36. The separation mechanism 50 includes an elastic plate 54, and a separation ring 55 is fixedly connected to the surface of the elastic plate 54.
[0022] The surface of the mounting ring 2 has mounting holes, and there are two sealing doors 3. The two sealing doors 3 are symmetrically arranged on the surface of the basalt fiber composite electrical box 1. The bottom of the meter 5 has wiring holes, and the inner wall of the basalt fiber composite electrical box 1 has a moving groove.
[0023] The positioning mechanism 10 includes a slide plate 11, a bent rod 12 fixedly connected to the surface of the slide plate 11, a slide rod 13 fixedly connected to the end of the bent rod 12, a return spring 14 fixedly connected to the surface of the slide rod 13, and a push rod 18 hinged to the end of the positioning ring 17. When the bent rod 12 moves, it pushes the slide rod 13 to slide against the top of the inner wall of the basalt fiber composite electrical box 1 on the inner wall of the moving groove, and at the same time pushes the return spring 14 to retract towards the meter 5. While the bent rod 12 moves, it pushes the end of the push rod 18 to move towards the meter 5, and the other end of the meter 5 pushes the positioning ring 17 to move towards each other.
[0024] The surface of the sliding plate 11 is slidably connected to the inner wall of the wiring hole. The end of the push rod 18 away from the positioning ring 17 is hinged to the inner wall of the bent rod 12. The end of the return spring 14 away from the bent rod 12 is fixedly connected to the bottom of the meter 5. The surface of the sliding rod 13 is slidably connected to the inner wall of the moving groove. The surface of the groove plate 15 is fixedly connected to the inner wall of the basalt fiber composite electrical box 1. When the positioning ring 17 moves, it will contact the wire, thereby positioning the wire. While the positioning ring 17 moves, it will drive the sliding plate 16 to slide towards each other on the inner wall of the groove plate 15. The wire can be quickly positioned after the positioning ring 17 moves into place, and the cumbersome steps of installing the wire with bolts are not required. At the same time, multiple wires can be installed inside the meter, thereby improving the efficiency of wire installation.
[0025] The self-locking mechanism 30 includes a support plate 31, a self-locking post 32 fixedly connected to the top of the support plate 31, a support ring 33 fixedly connected to the inner wall of the basalt fiber composite electrical box 1, U-shaped plates 34 fixedly connected to both sides of the support ring 33, a push plate 38 hinged to the end of the pull rod 37 away from the self-locking ring 36, and a driven telescopic rod 39 fixedly connected to the bottom of the push plate 38. When it is necessary to disassemble the wire, the operator only needs to press the push plate 38 and move it towards the support ring 33, and push the driven telescopic rod 39 to retract towards the support ring 33. When the push plate 38 moves, it will... The end of the push rod 37 is moved toward the self-locking ring 36, and the push rod 37 pushes the self-locking ring 36 to move away from each other. When the self-locking ring 36 moves, it pushes the reset elastic rod 35 to retract away from each other. At this time, the self-locking ring 36 separates from the inner wall of the self-locking groove, so that the positioning mechanism 10 is reset as a whole, and the wire can be taken out. The self-locking ring 36 can be effectively locked and fixed by the cooperation between the push rod 37 and the button plate 38. At the same time, the wire can be quickly disassembled, and the efficiency of wire disassembly is improved.
[0026] The bottom of the support plate 31 is fixedly connected to the surface of the return spring 14. The surface of the self-locking post 32 is provided with a self-locking groove. The end of the return elastic rod 35 away from the self-locking ring 36 is fixedly connected to the inner wall of the U-shaped plate 34. The end of the driven telescopic rod 39 away from the pressing plate 38 is fixedly connected to the end of the support ring 33. The inner wall of the self-locking ring 36 is adapted to the inner wall of the self-locking groove. When the self-locking groove moves to the center position of the self-locking ring 36, the self-locking post 32 no longer squeezes the self-locking ring 36. At this time, the self-locking ring 36 will be pushed by the elasticity of the return elastic rod 35 to move towards each other, so that the inner wall of the self-locking ring 36 contacts the inner wall of the self-locking groove, thereby completing the self-locking.
[0027] The separation mechanism 50 includes a right-angle plate 51, with a connecting plate 52 fixedly connected to the end of the right-angle plate 51. Two-way telescopic plates 53 are fixedly connected to both ends of the connecting plate 52. When the slide rod 13 moves, it will drive the right-angle plate 51 to move towards each other. When the right-angle plate 51 moves, it will push the connecting plate 52 to move towards each other. When the connecting plate 52 moves, it will push the two-way telescopic plates 53 to retract towards each other. When the two-way telescopic plates 53 retract, it will cause the two ends of the elastic plate 54 to move towards each other. During the movement of the elastic plate 54, the middle part will bend. When the middle part of the elastic plate 54 bends, it will push the separation ring 55 to move towards each other.
[0028] One end of the right-angle plate 51 away from the connecting plate 52 is fixedly connected to the bottom of the slide bar 13. Both ends of the elastic plate 54 are fixedly connected to the surface of the bidirectional telescopic plate 53. There are six right-angle plates 51, which are symmetrically arranged on the surface of the slide bar 13. During the movement of the separating ring 55, they will contact the surface of the wire to fix the wire. When the self-locking mechanism 30 and the positioning mechanism 10 are reset as a whole, the separating mechanism 50 will also be reset as a whole with the positioning mechanism 10, which facilitates the quick disassembly of the wire. Since there are three sets of elastic plates 54, three wires can be fixed. The elastic plates 54 can effectively reinforce the wires and separate them, improving the efficiency of wire sorting and preventing the wires from getting tangled together.
[0029] In use, the operator inserts the wire to be connected into the wiring hole. Once inserted, the wire contacts the surface of the sliding plate 11, pushing it to slide towards the inner wall of the wiring hole. As the sliding plate 11 slides, it moves the bent rod 12 towards the meter 5. This movement pushes the sliding rod 13 along the inner wall of the moving groove towards the top of the inner wall of the basalt fiber composite electrical box 1, simultaneously causing the return spring 14 to retract towards the meter 5. Simultaneously, the movement of the bent rod 12 pushes the end of the push rod 18 towards the meter 5, while the other end of the meter 5 pushes the positioning ring 17 towards a closer direction. During this movement, the positioning ring 17 contacts the wire, thus positioning it. As the sliding rod 13 moves, it causes the slide plate 16 to slide closer together on the inner wall of the groove plate 15. This effectively positions the wires quickly after the positioning ring 17 is in place, eliminating the need for cumbersome bolt installation. Multiple wires can be installed inside the meter, improving installation efficiency. When the sliding rod 13 slides, it moves the support plate 31 towards the support ring 33. This movement pushes the self-locking pin 32 towards the support ring 33. During this movement, the end of the self-locking pin 32 contacts the bottom of the self-locking ring 36. After contact, the self-locking ring 36 moves away from each other. When the self-locking ring 36 moves, it pushes the reset elastic rod 35 to retract towards each other. Simultaneously, the self-locking ring 36 moves, causing the end of the pull rod 37 to move away from each other. The other end of the pull rod 37 pulls the button plate 38 towards the support ring 33. As the button plate 38 moves, it pushes the driven telescopic rod 39 towards the support ring 33 to retract. When the self-locking groove moves to the center position of the self-locking ring 36, the self-locking pin 32 no longer presses against the self-locking ring 36. At this point, the self-locking ring 36, through the elasticity of the reset elastic rod 35, moves towards each other, causing the inner wall of the self-locking ring 36 to contact the inner wall of the self-locking groove, thus completing the self-locking. When it is necessary to disassemble the wire, the operator only needs to press the button plate 38 towards the support ring 33. The sliding rod 38 moves and pushes the driven telescopic rod 39 to retract towards the support ring 33. When the push plate 38 moves, it pushes the end of the pull rod 37 towards the self-locking ring 36. The pull rod 37 pushes the self-locking ring 36 to move away from each other. When the self-locking ring 36 moves, it pushes the reset elastic rod 35 to retract away from each other. At this time, the self-locking ring 36 separates from the inner wall of the self-locking groove, so that the positioning mechanism 10 is reset as a whole, thereby allowing the wire to be removed. The self-locking ring 36, pull rod 37 and push plate 38 can effectively lock and fix the wire, and can also quickly disassemble the wire, improving the efficiency of wire disassembly. When the sliding rod 13 moves, it will drive the right angle plate 51 to move towards each other.When the right-angle plate 51 moves, it pushes the connecting plate 52 to move closer to each other. When the connecting plate 52 moves, it pushes the bidirectional telescopic plate 53 to retract closer to each other. When the bidirectional telescopic plate 53 retracts, it causes the two ends of the elastic plate 54 to move closer to each other. During the movement of the elastic plate 54, the middle part bends. When the middle part of the elastic plate 54 bends, it pushes the separating ring 55 to move closer to each other. During the movement of the separating ring 55, it contacts the surface of the wire, thereby fixing the wire. Simultaneously with the overall reset of the self-locking mechanism 30 and the positioning mechanism 10, the separating mechanism 50 also resets along with the positioning mechanism 10, facilitating quick disassembly of the wire. Since there are three sets of elastic plates 54, three wires can be fixed. The elastic plates 54 effectively reinforce the wires and separate them, improving the efficiency of wire sorting and preventing the wires from tangling.
