Description

Technical Field

[0001] This utility model relates to the field of wire clamp technology, specifically a quick connection device for power transmission and distribution. Background Technology

[0002] In power transmission and distribution lines, clamps play a crucial role as key connecting components. Equipment clamps are used to connect busbar down conductors to the outgoing terminals of electrical equipment. Commonly used electrical equipment outgoing terminals are made of copper or aluminum, while the outgoing conductors are mostly aluminum stranded wire or steel-cored aluminum stranded wire. Therefore, equipment clamps are divided into two series: copper equipment clamps and copper-aluminum transition equipment clamps.

[0003] Publication No. CN214428781U discloses a power transmission and distribution line connection clamp. This device places the wire in an arc-shaped groove between a top cover and a bottom plate, then uses the top cover and bottom plate to press and fix it in both vertical directions. Two limiting brackets are pulled out, and a handwheel is used to rotate two screws. The two moving blocks and the fixed block are slidably connected. The rotation of the two screws drives the two moving blocks to move, thereby using the connecting block and pressing block at the port of the two moving blocks to press the wire on both sides. A first spring ensures that the fixed connecting block is always under the elastic force of the first spring, thus improving the fixing effect. The pressing block has an arc-shaped structure, which increases the contact area between the pressing block and the wire, further enhancing the fixing effect. However, this patent still has the following problems in actual use:

[0004] The device uses the rotation of two screws to drive two moving blocks, which in turn use the connecting block and pressing block at the port of the two moving blocks to press the wire on both sides. The first spring ensures that the fixed connecting block is always under the elastic force of the first spring, thus improving the fixing effect. However, the device's wiring clamp does not have an angle adjustment function after fixing the wire, which means that the wire at the output end of the electrical equipment can only be connected to the equipment in a fixed position and cannot be adjusted according to the actual use. This affects the subsequent wiring operation of the staff and brings limitations to the use of the device.

[0005] A fast connection device for power transmission and distribution is proposed to solve the problems mentioned above. Utility Model Content

[0006] The purpose of this utility model is to provide a quick connection device for power transmission and distribution, in order to solve the problem mentioned in the background art. Currently, the rotation of two screws drives two moving blocks to move, thereby using the connecting block and pressing block at the port of the two moving blocks to press the two sides of the wire. The first spring ensures that the fixed connecting block is always subject to the elastic force of the first spring, thus improving the fixing effect. However, the wiring clamp of this device does not have an angle adjustment function after fixing the wire, which means that the wire at the outlet of the electrical equipment can only be connected to the equipment at a fixed position and cannot be adjusted according to the actual use, affecting the subsequent wiring operation of the staff and bringing limitations to the staff when using it.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a quick connection device for power transmission and distribution, comprising a base plate, a circular plate on one side of the base plate, a first arc-shaped plate fixedly connected to one side of the circular plate, and a second arc-shaped plate on one side of the first arc-shaped plate, with rubber pads provided on the inner sides of both the first and second arc-shaped plates; an adjustment mechanism is provided inside the base plate, and a fixing component is provided between the first and second arc-shaped plates;

[0008] The adjustment mechanism includes a circular box installed inside the base plate, with a rotating shaft rotatably connected inside the circular box. A gear plate is installed on the outer side of the rotating shaft, and inclined teeth are installed on the outer side of the gear plate. A fixing block is installed on the inner side of the circular box, and a clamping plate is installed on one side of the fixing block. A rotating rod is rotatably connected inside the clamping plate, and a connecting rod is installed on the outer side of the rotating rod. Torsion springs are provided between the two ends of the rotating rod and the clamping plate. A stop block is installed on the inner side of the circular box.

[0009] Preferably, a scale line is provided on one side of the base plate, and a positioning hole is provided on the side of the base plate near the scale line. A pointer is installed on one side of the circular plate, and a fixing knob is threadedly connected to the inside of the pointer. One end of the fixing knob is threadedly connected to the positioning hole.

[0010] Preferably, the fixing assembly includes a screw symmetrically rotatably connected to one side of the first arc-shaped plate, one end of which passes through the second arc-shaped plate and is threadedly connected to the second arc-shaped plate. Support rods are symmetrically installed on one side of the first arc-shaped plate, one end of which passes through the second arc-shaped plate and is slidably connected to the second arc-shaped plate. Support plates are symmetrically installed on one side of the second arc-shaped plate, and insert rods are slidably connected inside the support plates. A retaining ring is installed on the outer side of one end of the insert rod, and a retraction spring is sleeved on the outer side of the insert rod. Slots are provided on one side of each support rod, and one end of the insert rod is inserted into the slot.

[0011] Preferably, a rotating block is installed at one end of the screw.

[0012] Preferably, one end of the connecting rod is engaged with the inclined teeth.

[0013] Preferably, the scale lines correspond to the positioning holes.

[0014] Preferably, one end of the rotating shaft is fixedly connected to the circular plate.

[0015] Compared with existing technologies, the beneficial effects of this utility model are as follows: A quick connection device for power transmission and distribution, specifically, involves a worker rotating a circular plate to drive a rotating shaft inside a circular box. This rotation of the shaft drives a gear plate, which in turn drives multiple sets of inclined teeth. These inclined teeth press against a connecting rod, causing the connecting rod to rotate inside a clamping plate. A torsion spring extends, and when the gear plate rotates a certain angle, the torsion spring quickly contracts and resets. At this point, one end of the connecting rod rapidly strikes the inclined teeth, producing a "click" sound. This causes the circular plate to rotate, adjusting the first and second arc-shaped plates to a specific angle. This allows the first and second arc-shaped plates to be quickly adjusted to the required angle, improving installation and wiring efficiency. The click feedback mechanism ensures that each adjustment reaches the predetermined angle, facilitating quick confirmation and adjustment by the worker. The adjustment mechanism allows the connector clamp to adapt to more different specifications and angles. The wiring and equipment are improved in terms of adaptability and flexibility. Whether it is a straight connection or a corner connection, the junction box can provide a stable electrical connection. During maintenance, the audible feedback also helps to quickly identify and adjust the status of the junction box, ensuring the normal operation of the electrical system. When the operator rotates two sets of screws, the first arc plate rotates. At this time, the rotation of the two sets of screws drives the movement of the second arc plate. The second arc plate slides outside the support rod. The movement of the second arc plate, together with the first arc plate, fixes the wire. Then, the operator pulls two sets of plug rods to slide inside the support plate. The movement of the plug rods drives the movement of the retaining ring. The movement of the retaining ring compresses the compression spring. The tension generated by the compression spring makes one end of the plug rod insert into the slot. At this time, the first arc plate and the support rod are fixedly connected. This can achieve the effect of quickly adjusting and fixing the position of the first arc plate, thus meeting the fixing effect of various specifications of wires, thereby greatly improving the applicability of the device.

[0016] 1. The operator rotates a circular plate, causing a rotating shaft to rotate inside the circular box. This rotation of the shaft drives a geared disc, which in turn drives multiple sets of inclined teeth. These inclined teeth press against the connecting rod, causing it to rotate inside the clamping plate. A torsion spring extends, and when the geared disc rotates a certain angle, the torsion spring quickly contracts and returns to its original position, causing the connecting rod to rotate and return to its original position. At this point, one end of the connecting rod strikes the inclined teeth, producing a "click" sound. This indicates that one end of the connecting rod is now positioned between two sets of inclined teeth. The rotation of the circular plate causes the first and second arc-shaped plates to adjust to a specific angle. The operator uses this continuous sound feedback to determine the angle of the wire rotation, allowing the first and second arc-shaped plates to be quickly adjusted to the required angle. This improves installation and wiring efficiency. The click feedback mechanism ensures that each adjustment reaches the predetermined angle, facilitating quick confirmation and adjustment by the operator. The design allows the connector to adapt to a wider range of wires and equipment with different specifications and angles, improving its adaptability and flexibility. Whether for straight or corner connections, the connector provides a stable electrical connection. During maintenance, audible feedback helps to quickly identify and adjust the connector's status, ensuring the normal operation of the electrical system and providing convenience for operators. The rotation of the circular plate drives the rotation of the pointer, allowing operators to observe the pointer and scale. When the wire reaches the appropriate angle, the operator tightens the fixing knob, creating a threaded connection between the fixing knob and the corresponding positioning hole, thus fixing the pointer. The design of the pointer and scale allows operators to more intuitively observe the wire angle adjustment, greatly improving the accuracy of wire angle adjustment. Furthermore, the fixing knob's limit on the pointer effectively prevents external forces from causing the circular plate to rotate, significantly improving the stability of the wire after installation and providing convenience for operators.

[0017] 2. By rotating two sets of screws on the first arc-shaped plate, the rotation of the screws causes the second arc-shaped plate to move, sliding outside the support rod. This movement of the second arc-shaped plate, in conjunction with the first arc-shaped plate, secures the wire. The rubber pad is compressed and deformed, utilizing its plasticity and high friction to achieve stable wire installation. The operator then pulls two sets of insertion rods, which slide inside the support plate. This movement of the insertion rods causes the retaining ring to move, compressing the compression spring. Releasing the insertion rods allows the tension generated by the compression spring to insert one end of the insertion rod into the slot, thus fixing the first arc-shaped plate to the support rod. This enables quick adjustment and fixation of the first arc-shaped plate, accommodating various wire specifications and greatly expanding the device's applicability, providing convenience for users.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-6 The present invention provides a technical solution: a quick connection device for power transmission and distribution, comprising a base plate 1, a circular plate 101 disposed on one side of the base plate 1, a first arc-shaped plate 102 fixedly connected to one side of the circular plate 101, and a second arc-shaped plate 103 disposed on one side of the first arc-shaped plate 102, and rubber pads 104 disposed on the inner sides of both the first arc-shaped plate 102 and the second arc-shaped plate 103; an adjustment mechanism 2 is disposed inside the base plate 1, and a fixing component 3 is disposed between the first arc-shaped plate 102 and the second arc-shaped plate 103;

[0027] The adjusting mechanism 2 includes a circular box 201 installed inside the base plate 1. A rotating shaft 202 is rotatably connected inside the circular box 201. One end of the rotating shaft 202 is fixedly connected to the circular plate 101. A gear plate 203 is mounted on the outer side of the rotating shaft 202, and inclined teeth 204 are mounted on the outer side of each gear plate 203. A fixing block 205 is mounted on the inner side of the circular box 201, and a clamping plate 206 is mounted on one side of each fixing block 205. A rotating rod 207 is rotatably connected inside the clamping plate 206, and a connecting rod 208 is mounted on the outer side of the rotating rod 207. One end of the connecting rod 208 meshes with the inclined teeth 204. Torsion springs 209 are provided between both ends of the rotating rod 207 and the clamping plate 206. Stops 210 are mounted on the inner side of the circular box 201, thereby allowing the circular plate 101 to... The rotation drives the first arc plate 102 and the second arc plate 103 to adjust to a certain angle. At this time, the staff judges the angle of the wire rotation based on the continuous sound feedback, so that the first arc plate 102 and the second arc plate 103 can be quickly adjusted to the required angle, improving the efficiency of installation and wiring. The click sound feedback mechanism ensures that the predetermined angle is reached every time, which makes it easy for the staff to quickly confirm and adjust. The adjustment mechanism 2 enables the connector to adapt to more wires and equipment of different specifications and angles, improving its adaptability and flexibility. Whether it is a straight connection or a corner connection, the connector can provide a stable electrical connection. During maintenance, the sound feedback also helps to quickly identify and adjust the status of the connector, ensuring the normal operation of the electrical system and bringing convenience to the staff when using it.

[0028] Each side of the base plate 1 has a scale line 211, and each side of the base plate 1 near the scale line 211 has a positioning hole 212. The scale line 211 and the positioning hole 212 correspond to each other. A pointer 213 is installed on one side of the circular plate 101, and a fixing knob 214 is threaded inside the pointer 213. One end of the fixing knob 214 is threaded to the positioning hole 212. Through the design of the pointer 213 and the scale line 211, it is convenient for the staff to observe the wire angle adjustment more intuitively, thereby greatly improving the accuracy of wire angle adjustment. Furthermore, the fixing knob 214 limits the pointer 213, which can effectively prevent the circular plate 101 from rotating due to external forces, greatly improving the stability of the wire after installation and bringing convenience to the staff during use.

[0029] The fixing component 3 includes a screw 301 symmetrically rotatably connected to one side of the first arc-shaped plate 102, with one end of the screw 301 passing through the second arc-shaped plate 103 and threadedly connected to it. A support rod 302 is symmetrically mounted on one side of the first arc-shaped plate 102, with one end of the support rod 302 passing through the second arc-shaped plate 103 and slidably connected to it. A support plate 303 is symmetrically mounted on one side of the second arc-shaped plate 103, with an insert rod 304 slidably connected inside the support plate 303, and a [missing information - likely a device or component] mounted on the outer side of one end of the insert rod 304. The retaining ring 305 and the outer side of the insertion rod 304 are fitted with a retraction spring 306. The support rod 302 has a slot 307 on one side. One end of the insertion rod 304 is inserted into the slot 307. One end of the screw 301 is equipped with a rotating block 308, which can quickly adjust and fix the position of the first arc plate 102, thereby meeting the fixing effect of various specifications of wires. This greatly improves the applicability of the device and brings convenience to the staff when using it. The design of the rotating block 308 makes it easy for the staff to operate the screw 301.

[0030] Working principle: Before using this type of fast connection device for power transmission and distribution, it is necessary to check the overall condition of the device to ensure that it can operate normally. Figure 1 - Figure 6As shown, the operator rotates the circular plate 101, causing the rotating shaft 202 to rotate inside the circular box 201. This rotation of the shaft 202 drives the rotation of the gear disc 203, which in turn drives the rotation of multiple sets of inclined teeth 204. These inclined teeth 204 then compress the connecting rod 208, causing the connecting rod 208 to rotate inside the clamping plate 206. At this time, the torsion spring 209 extends. When the gear disc 203 rotates a certain angle, the torsion spring 209 quickly contracts and returns to its original position, causing the connecting rod 208 to quickly rotate and return to its original position. One end of the connecting rod 208 is rapidly struck against the inclined teeth 204, producing a "click" sound. At this point, one end of the connecting rod 208 is positioned between the two sets of inclined teeth 204, causing the circular plate 101 to rotate and adjust the first arc plate 102 and the second arc plate 103 to a certain angle. The operator judges the angle of the wire rotation based on the continuous sound feedback, enabling the first arc plate 102 and the second arc plate 103 to quickly adjust to the required angle. This improves the efficiency of installation and wiring, and the click feedback mechanism ensures that each adjustment reaches the predetermined angle. The adjustment mechanism 2 allows the connector to be adapted to a wider range of wires and equipment with different specifications and angles, improving its adaptability and flexibility. Whether it is a straight connection or a corner connection, the connector can provide a stable electrical connection. During maintenance, the sound feedback also helps to quickly identify and adjust the status of the connector, ensuring the normal operation of the electrical system and bringing convenience to the staff. The rotation of the circular plate 101 drives the rotation of the pointer 213. At this time, the staff observes the pointer 213 and the scale line 211. When the wire reaches the appropriate angle, the staff tightens the fixing knob 214, so that the fixing knob 214 is threadedly connected to the corresponding positioning hole 212, thereby achieving the effect of fixing the pointer 213. Through the design of the pointer 213 and the scale line 211, the staff can more intuitively observe the wire angle adjustment, thereby greatly improving the accuracy of the wire angle adjustment. In addition, the fixing knob 214 limits the pointer 213, which can effectively prevent the circular plate 101 from rotating due to external forces, greatly improving the stability of the wire after installation and bringing convenience to the staff.

[0031] The operator rotates two sets of screws 301 on the first arc-shaped plate 102. This rotation causes the second arc-shaped plate 103 to move, sliding it outside the support rod 302. The movement of the second arc-shaped plate 103, in conjunction with the first arc-shaped plate 102, secures the wire. The rubber pad 104 is compressed and deformed, utilizing its plasticity and high friction to achieve stable wire installation. The operator then pulls the two sets of insertion rods 304, which slide inside the support plate 303. This movement of the insertion rods 304 then moves the retaining ring 305. The movement of the retaining ring 305 compresses the retraction spring 306, and then releases the insertion rod 304. The tension generated by the retraction spring 306 causes one end of the insertion rod 304 to be inserted into the slot 307. At this time, the first arc plate 102 and the support rod 302 are fixedly connected, thereby achieving the effect of quickly adjusting and fixing the position of the first arc plate 102. This can meet the fixing effect of various specifications of wires, thus greatly improving the applicability of the device and bringing convenience to the staff during use. The design of the rotating block 308 makes it easy for the staff to operate the screw 301.

[0032] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
