Description

Technical Field

[0001] The invention belongs to the technical field of high-voltage equipment, and in particular relates to a bellows connecting device for a high-voltage combined electrical appliance. Background Art

[0002] In high-voltage combination electrical appliances, wires and insulating sheaths are extremely fragile and are easily damaged and disturbed by various external forces. The corrugated tube can provide a reliable barrier to isolate the wiring harness from the external environment, thereby protecting the wiring harness from various potential hazards such as impact, wear, and friction. This protection mechanism greatly reduces the risk of dangerous situations such as local short circuit or explosion due to damage to the wiring harness, and significantly improves the safety and stability of the wiring harness operation. In order to ensure that the corrugated tube can firmly play its protective role, through the fixation and support of the bellows connecting device, the bellows can more effectively play its isolation and protection role, providing strong guarantee for the stable operation of the high-voltage combination electrical appliances.

[0003] In high-voltage combination electrical appliances, especially those that need to be frequently moved or connected, the length of the wiring harness will change due to external factors such as thermal expansion and contraction. The bellows can adjust the length of the wiring harness by expanding and contracting, ensuring that the wiring harness is tightly connected and does not fall off or drag on the ground. However, during use, the existing bellows connection device, that is, after experiencing displacement changes, the bellows is often difficult to quickly and accurately return to its original state during the subsequent re-absorption and compensation process, affecting the stability and reliability of the wiring harness connection. Summary of the invention

[0004] In order to overcome the deficiencies of the prior art, the purpose of the present invention is to provide a bellows connection device for a high-voltage combination electrical appliance to solve the problem that after the bellows undergoes displacement changes, it is difficult for the bellows to quickly and accurately return to its original state in the subsequent re-absorption and compensation process.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0006] A high-voltage combined electrical appliance bellows connection device, comprising:

[0007] Bellows body;

[0008] Both ends of the bellows body are installed with connection structures, and the outer surfaces of the two connection structures are fixedly interspersed with connection plates, and multiple compensation structures are installed between the connection plates;

[0009] The compensation structure includes a connecting block, a movable rod, a support frame, a mounting block and a joint structure. The movable rod, the support frame and the mounting block are each provided with two, and the two movable rods are respectively movably connected to the two ends of the connecting block, the two support frames are respectively fixedly connected to one end of the movable rod away from the connecting block, the two mounting blocks are respectively installed at the bottom ends of the two support frames, and the joint structure is installed in the middle of the bottom end of the connecting block;

[0010] The joint structure includes a second spring, a base, a support plate, a fixed seat, a connecting rod, a movable column and a support block. The base and the support plate are respectively fixedly connected to the top end and the bottom end of the second spring. The fixed seat is arranged in the middle of the bottom end of the support plate. The connecting rod is installed and connected in the fixed seat. There are two movable columns and two support blocks. The two movable columns are respectively movably connected to the two ends of the two movable columns away from the connecting rod. The base is arranged in the middle of the bottom end of the connecting block.

[0011] Preferably, a mounting plate is installed on the outer surface of one end of the two connecting structures away from the corrugated pipe body, a screw is movably inserted and connected in the mounting plate, a fastening nut is threadedly connected to the outer surface of one end of the screw, the end of the screw away from the mounting plate passes through the connecting plate and is fixedly connected to a fixing block, and a first spring is sleeved on the outer surface of the screw.

[0012] Preferably, one end of the fixing block is fixedly connected to the outer surface of the connecting structure, and two ends of the first spring are fixedly connected to the opposite surfaces of the connecting plate and the mounting plate respectively.

[0013] Preferably, the two mounting blocks are respectively mounted on outer surfaces of the two connecting plates.

[0014] Preferably, the two support blocks are fixedly connected to one end of the two connecting plates respectively.

[0015] Preferably, the connecting structure includes a movable tube and a fixed tube, the movable tube is movably connected to the outer surface of the fixed tube, a plurality of limit grooves are equidistantly provided on one side of the outer surface of the movable tube, a plurality of screw rods are equidistantly fixedly connected to the outer surface of the fixed tube, a fastening block is threadedly connected to the outer surface of the screw rods, and the movable tube is installed in the connecting plate.

[0016] Preferably, one end of the fixed tube away from the movable tube is installed in the mounting plate.

[0017] Preferably, the plurality of screw rods are respectively located in corresponding limiting grooves.

[0018] Preferably, one end of the fastening nut is tightly attached to one end of the mounting plate, and the fixing blocks are fixedly connected to the outer surface of the movable tube.

[0019] Preferably, the support frames are all configured as L-shaped structures, and the mounting blocks are all configured as arc-shaped structures.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] (1) By setting the second spring, the support plate, the fixed seat, the connecting rod, the movable column and the support block, when the bellows body is displaced, the connecting plate will first drive the support block to move accordingly, and the movement of the support block will then drive the movable column to move accordingly. The movable column is connected to the fixed seat through the connecting rod, thereby pulling the fixed seat to move, and the displacement of the fixed seat drives the movement of the support plate. At this time, the support plate will stretch the second spring to make it in an extended state. In the subsequent displacement absorption and compensation process of the bellows body, the second spring can quickly drive the support plate to move in the opposite direction by virtue of its excellent reset characteristics. This series of displacement transmission, through the support plate, the fixed seat, the connecting rod, the movable column and the support block, ultimately causes the bellows body to return to its initial state at a faster speed and higher stability. This mechanism not only significantly improves the reset stability of the bellows body, but also ensures that the bellows can quickly and stably return to its normal working state after experiencing displacement, thereby providing a solid guarantee for the stable operation of the high-voltage combination electrical appliance in various complex environments.

[0022] (2) By setting the connecting block, movable rod, support frame and mounting block, when the connecting plate moves, it will drive the support frame to move accordingly through the mounting block installed on it, and the movement of the support frame further drives the movable rod to slide smoothly inside the connecting block. This design not only ensures the stable support of the joint structure, but also significantly improves its overall stability and performance. Specifically, the connecting block provides a stable sliding track for the movable rod, and the movable rod is connected to the connecting plate through the support frame, forming a tight linkage system. When the connecting plate is displaced by external force, this displacement will be quickly and accurately transmitted to the support frame through the mounting block, and the support frame will further drive the movable rod to slide in the connecting block, thereby achieving comprehensive and stable support for the joint structure. This mechanism not only enhances the overall stability of the joint structure, but also significantly improves its performance in various complex environments, providing a strong guarantee for the stable operation of high-voltage combination electrical appliances.

[0023] (3) By setting the fastening nut, the first spring, the fixed block, the movable tube, the limit groove, the fixed tube, the screw and the fastening block, when the bellows body absorbs and compensates for the displacement caused by the change of the external environment, it will drive the movable tube to slide smoothly along the outer surface of the fixed tube. In this process, the displacement of the movable tube not only realizes the direct response to the displacement of the bellows body, but also drives the synchronous movement of the fixed block. The movement of the fixed block further promotes the stable sliding of the screw in the mounting plate. This design not only enhances the continuity and accuracy of the displacement transmission, but also provides additional stability for the entire system. At the same time, when the connecting plate moves with the movable tube, it will gradually The first spring is squeezed to shrink. The introduction of this elastic element not only increases the flexibility and adaptability of the system, but also helps to absorb and alleviate impact force during the displacement process and protect the system from damage. In addition, the combination of the screw rod and the limit groove is used to accurately limit the movable tube. By adjusting the position of the screw rod in the limit groove, the movement range and displacement accuracy of the movable tube can be effectively controlled, thereby further improving the stability and reliability of the displacement of the bellows body. This design not only ensures the stability and accuracy of the bellows body during the displacement process, but also provides a solid guarantee for the stable operation of the high-voltage combination electrical appliance in various complex environments.

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] Embodiment 1:

[0033] See also Figure 1 - Figure 6 As shown, a high-voltage combined electrical appliance bellows connection device comprises:

[0034] Bellows body 1;

[0035] Both ends of the bellows body 1 are installed with connection structures 2, and the outer surfaces of the two connection structures 2 are fixedly interlaced with connection plates 3, and multiple compensation structures 4 are installed between the connection plates 3;

[0036] The compensation structure 4 includes a connecting block 41, a movable rod 42, a support frame 43, a mounting block 44 and a joint structure 45. The movable rod 42, the support frame 43 and the mounting block 44 are each provided with two, and the two movable rods 42 are respectively movably connected to the two ends of the connecting block 41, the two support frames 43 are respectively fixedly connected to the ends of the movable rod 42 away from the connecting block 41, the two mounting blocks 44 are respectively installed at the bottom ends of the two support frames 43, and the joint structure 45 is installed in the middle of the bottom end of the connecting block 41;

[0037] The joint structure 45 includes a second spring 451, a base 452, a support plate 453, a fixed seat 454, a connecting rod 455, a movable column 456 and a support block 457. The base 452 and the support plate 453 are respectively fixedly connected to the top and bottom ends of the second spring 451, the fixed seat 454 is arranged in the middle of the bottom end of the support plate 453, the connecting rod 455 is installed and connected in the fixed seat 454, and two movable columns 456 and support blocks 457 are each provided with two, and the two movable columns 456 are respectively movably connected to both sides of the outer surface of the connecting rod 455, and the two support blocks 457 are respectively movably connected to the ends of the two movable columns 456 away from the connecting rod 455, and the base 452 is arranged in the middle of the bottom end of the connecting block 41.

[0038] As can be seen from the above, when the connecting plate 3 moves, it will drive the support frame 43 to move through the mounting block 44 installed therewith, and the support frame 43 drives the movable rod 42 fixedly connected therewith to slide in the connecting block 41, and at the same time, the connecting plate 3 will drive the support block 457 fixedly connected therewith to move, and the support block 457 drives the movable column 456 movably connected therewith to move, and the movable column 456 pulls the fixed seat 454 to move through the connecting rod 455 movably connected therewith, and the fixed seat 454 drives the support plate 453 fixedly connected therewith to move, and the support plate 453 pulls the movable column 456 fixedly connected therewith to move. The second spring 451 extends, and in the subsequent absorption and compensation process of the bellows body 1, the reset effect of the second spring 451 can quickly drive the support plate 453 to move, and the support plate 453 drives the fixed seat 454 to move, and the fixed seat 454 pulls the movable column 456 to move through the connecting rod 455, so that the movable column 456 drives the connecting plate 3 to move through the supporting block 457, and the connecting plate 3 pulls the connecting structure 2 to move, thereby improving the reset stability of the bellows body 1, ensuring that the bellows can recover to the initial state more quickly and stably after displacement.

[0039] Preferably, the two mounting blocks 44 are respectively mounted on the outer surfaces of the two connecting plates 3;

[0040] The two support blocks 457 are respectively fixedly connected to one end of the two connecting plates 3;

[0041] The support frames 43 are all configured as L-shaped structures, and the mounting blocks 44 are all configured as arc-shaped structures.

[0042] As can be seen from the above, the mounting block 44 is installed on the outer surface of the connecting plate 3, so that when the connecting plate 3 moves, the supporting frame 43 can be driven to move by the mounting block 44. The mounting block 44 is set to an arc structure, so that it can better fit the outer surface of the connecting plate 3.

[0043] Embodiment 2:

[0044] refer to Figure 1 and Figure 6 As shown, the outer surfaces of the ends of the two connecting structures 2 away from the bellows body 1 are both installed with mounting plates 5, and screws 6 are movably inserted and connected in the mounting plates 5. The outer surfaces of one ends of the screws 6 are threadedly connected with fastening nuts 7, and the ends of the screws 6 away from the mounting plates 5 penetrate the connecting plate 3 and are fixedly connected with a fixing block 9, and the outer surfaces of the screws 6 are both sleeved with first springs 8.

[0045] It can be seen from the above that when the connecting structure 2 is displaced, it can drive the fixed block 9 fixedly connected to it to be displaced, and the fixed block 9 pushes the screw 6 fixedly connected to it to slide in the mounting plate 5, and during the movement, the connecting plate 3 will squeeze the first spring 8, causing the first spring 8 to contract, thereby improving the stability of the displacement of the corrugated tube body 1.

[0046] Preferably, one end of the fixing block 9 is fixedly connected to the outer surface of the connecting structure 2 , and both ends of the first spring 8 are fixedly connected to the opposite surfaces of the connecting plate 3 and the mounting plate 5 .

[0047] As can be seen from the above, the first spring 8 is connected to the connecting plate 3 and the mounting plate 5. When the connecting plate 3 moves with the displacement of the movable tube 21, it will gradually squeeze the first spring 8, causing the first spring 8 to elastically contract. This design not only cleverly utilizes the elastic characteristics of the first spring 8 to absorb and alleviate the impact force generated during the displacement process, but also effectively improves the stability and reliability of the entire system.

[0048] Embodiment three:

[0049] refer to Figure 5 and Figure 6 As shown, the connection structure 2 includes a movable tube 21 and a fixed tube 23. The movable tube 21 is movably inserted and connected to the outer surface of the fixed tube 23. A plurality of limit grooves 22 are equidistantly provided on one side of the outer surface of the movable tube 21. A plurality of screw rods 24 are equidistantly fixedly connected to the outer surface of the fixed tube 23. The outer surfaces of the screw rods 24 are all threadedly connected to fastening blocks 25. The movable tube 21 is installed in the connecting plate 3.

[0050] As can be seen from the above, the bellows body 1 drives the movable tube 21 fixedly connected thereto to displace, the movable tube 21 slides on the outer surface of the fixed tube 23, and drives the connecting plate 3 fixedly interlaced therewith to displace, and the movable tube 21 can be limited by the screw rod 24 and the limiting groove 22, thereby improving the stability of the displacement of the movable tube 21.

[0051] Preferably, one end of the fixed tube 23 away from the movable tube 21 is installed in the mounting plate 5;

[0052] A plurality of screw rods 24 are respectively located in corresponding limiting grooves 22;

[0053] One end of the fastening nut 7 is tightly attached to one end of the mounting plate 5 , and the fixing blocks 9 are fixedly connected to the outer surface of the movable tube 21 .

[0054] As can be seen from the above, the screw rod 24 is set in the limit groove 22. Through the close cooperation between the screw rod 24 and the limit groove 22, the moving range of the movable tube 21 can be accurately controlled, thereby effectively preventing it from deviating from the original set position during operation. The fixed block 9 is fixed to the outer surface of the movable tube 21, and can drive the fixed block 9 to move when the movable tube 21 is displaced.

[0055] Furthermore, the present invention is designed and applied in the power line protection of high-voltage combination electrical appliances. Under high-voltage environment, when the high-voltage combination electrical appliances are affected by external factors such as thermal expansion and contraction, when displacement occurs, the bellows body 1 pulls the movable tube 21 firmly connected thereto to move together, and the movable tube 21 slides smoothly along the outer wall of the fixed tube 23, and links the connecting plate 3 tightly interlaced therewith to move. As the connecting plate 3 moves, it drives the support frame 43 to move accordingly through the mounting block 44 installed thereon, and the support frame 43 then pulls the movable rod 42 fixedly connected thereto to slide smoothly inside the connecting block 41. At the same time, the movement of the connecting plate 3 also drives the displacement of the supporting block 457 fixed thereto, and the supporting block 457 is movable through the movable interlaced connection. The column 456 pulls the fixed seat 454 to move via the connecting rod 455. The displacement of the fixed seat 454 drives the movement of the support plate 453, thereby stretching the second spring 451 fixedly connected thereto. In the subsequent displacement absorption and compensation process of the bellows body 1, the second spring 451 quickly drives the support plate 453 to move in the opposite direction by virtue of its reset function. This series of actions, through the fixed seat 454, the connecting rod 455, the movable column 456, and the support block 457, finally prompts the connecting plate 3 to pull the movable tube 21 back to its original position, significantly improving the reset stability of the bellows body 1 and ensuring that the bellows can be restored to its initial state more quickly and stably after displacement, which is crucial to ensuring the stable operation of the high-voltage combination electrical appliance in various complex environments.

[0056] In addition, the displacement of the movable tube 21 also drives the movement of the fixed block 9 fastened thereto, and the fixed block 9 then pushes the screw 6 to slide smoothly in the mounting plate 5. During the displacement process, the connecting plate 3 will also compress the first spring 8, causing it to shrink. This design further enhances the stability of the bellows body 1 during the displacement process.
