[0002] The existing application publication number "CN102568710A" proposes a large-tonnage disc-shaped suspended glass insulator. By designing the head of the glass piece into a cylindrical shape and a staggered umbrella skirt structure, and by reasonably matching the insulator size, the product strength grade can reach 76 tons. In actual use, the number of parallel strings can be reduced, so that the construction of ultra-high voltage power transmission lines greatly saves materials and space, and the safety performance is greatly improved. The existing conventional glass insulator includes an iron cap, a glass piece and a steel foot. The iron cap and the steel foot are respectively installed at the upper and lower ends of the glass piece.

[0021] See also Figure 1-Figure 9The present invention provides a disc-shaped insulator with a connection structure, comprising a disc-shaped insulator body 100, a docking column 101 is fixed to the top surface of the disc-shaped insulator body 100, a docking tube 102 is fixed to the bottom surface of the disc-shaped insulator body 100, four first racks 104 distributed in a circumference are fixed to the middle of the outer wall of the docking column 101, four cylindrical holes 105 distributed in a circumference are opened near the middle of the outer wall of the docking tube 102, a gear 106 is movably connected in the cylindrical hole 105, four second racks 107 distributed in a circumference are arranged on the periphery of the docking tube 102, the The second rack 107 is meshed with the corresponding gear 106, and the inner wall of the butt joint tube 102 is provided with four inner grooves 103 distributed in a circle, and a fixed frame 300 is fixed on the outer wall of the butt joint tube 102 near the top, and the bottom surface of the fixed frame 300 is provided with four second T-shaped grooves 301 distributed in a circle, and two second T-shaped blocks 302 are movably connected in the second T-shaped grooves 301, and a rotating rod 303 is movably connected to the bottom of the second T-shaped block 302, and a resistance block 304 is movably connected between the bottoms of two adjacent rotating rods 303, and a pulling component is arranged on the periphery of the butt joint tube 102.

[0022] When two disc-shaped insulator bodies 100 are butted together, the butt joint post 101 on one disc-shaped insulator body 100 is inserted into the butt joint pipe 102 at the bottom of the other disc-shaped insulator body 100, so that the first rack 104 at the top of one disc-shaped insulator body 100 is engaged with the inner groove 103 in the butt joint pipe 102 at the bottom of the other disc-shaped insulator body 100, until the gear 106 is engaged with the top of the side of the first rack 104, and then the pull assembly is pulled down to make the two second T-blocks 302 approach each other, so that the two second T-blocks 302 are relatively close to each other. As the two rotating rods 303 approach each other, the abutment block 304 is pushed and contacts the second rack 107, pushing the second rack 107 downward, and the downward movement of the second rack 107 drives the gear 106 to rotate, thereby causing the first rack 104 to move upward, and the upward movement of the first rack 104 drives the docking post 101 on the bottom disc-shaped insulator body 100 to move upward. This arrangement can push the second rack 107 to move, and at the same time realize the connection between the docking post 101 and the docking tube 102, thereby improving the installation efficiency of the disc-shaped insulator body 100.

[0023] In one embodiment, if Figure 6 As shown, the pulling assembly includes a fixing ring 200, and the fixing ring 200 is fixed to the outer wall of the butt joint tube 102 near the middle position. The top surface of the fixing ring 200 is movably connected with a first limiting column 400, and the top surface of the first limiting column 400 is fixed with a trapezoidal frame 401. When the trapezoidal frame 401 moves downward, it can drive the resistance block 304 to move downward, thereby causing the second rack 107 to move downward. This setting method can change the position of the resistance block 304, thereby adjusting the position of the second rack 107.

[0024] In one embodiment, if Figure 6 As shown, a connecting ring 402 is fixed to the bottom surface of the first limiting column 400, and four first arc-shaped racks 404 distributed in a circle are fixed to the top surface of the connecting ring 402. A limiting groove 405 is provided on the bottom surface of the fixing ring 200, and a limiting ring 406 is movably connected in the limiting groove 405. Four U-shaped frames 407 distributed in a circle are fixed to the top surface of the limiting ring 406, and a second arc-shaped rack 408 is fixed to the bottom surface of the U-shaped frame 407. The second arc-shaped rack 408 is meshed with the first arc-shaped rack 404. During the downward movement of the trapezoidal frame 401, the second arc-shaped rack 408 gradually moves out of the top hole 403 until the second arc-shaped rack 408 is located above the top hole 403. At this time, the first arc-shaped rack 404 and the second arc-shaped rack 408 are staggered and there is a gap in the middle. Then, the U-shaped frame 407 can be rotated to rotate the second arc-shaped rack 408. At this time, the second arc-shaped rack 40 8 is relatively distributed with the first arc-shaped rack 404, and then the pulling of the pulling assembly is released, the second spring 502 pushes the second rack 107 to move upward, and then pushes the contact block 304 to move upward, the contact block 304 moves upward to drive the trapezoidal frame 401 to move upward, and the trapezoidal frame 401 moves upward to drive the first arc-shaped rack 404 to move upward, so that the first arc-shaped rack 404 is meshed with the second arc-shaped rack 408. Since the first arc-shaped rack 404 and the second arc-shaped rack 408 are relatively arranged, in this arrangement, the first arc-shaped rack 404 realizes the limitation of the trapezoidal frame 401 through the action relationship of support and meshing, and finally the two disc-shaped insulator bodies 100 are stably connected together, which effectively ensures the stability of the connection of the two disc-shaped insulator bodies 100. At the same time, this structural design can conveniently and quickly realize the connection of the two disc-shaped insulator bodies 100, thereby improving the connection efficiency of the disc-shaped insulator bodies 100.

[0025] In one embodiment, if Figure 6 As shown, a top hole 403 is provided on the bottom surface of the connecting ring 402. The top hole 403 can prevent the U-shaped frame 407 and the connecting ring 402 from interfering with each other when the two disc-shaped insulator bodies 100 are not finally stably connected.

[0026] The top hole 403 corresponds to the initial position of the second arc-shaped rack 408 .

[0027] In one embodiment, if Figure 5As shown, side rods 306 are fixed to the sides away from each other relative to the two abutment blocks 304, and the outer wall of the side rods 306 is provided with slots 307, and rollers 308 are movably connected in the slots 307, and the rollers 308 cooperate with the trapezoidal frame 401. The side rods 306 and the rollers 308 can cooperate with the trapezoidal frame 401, so that when the trapezoidal frame 401 moves, the rollers 308 can slide on the inner wall of the trapezoidal frame 401, so as to facilitate the relative approach of the two second T-blocks 302 to each other.

[0028] In one embodiment, if Figure 4 As shown, inner columns 309 are fixed to the two opposite side surfaces of the inner wall of the second T-slot 301, the second T-block 302 is movably connected to the inner column 309, and the outer wall of the inner column 309 is provided with a first spring 310. The inner column 309 and the first spring 310 enable the first spring 310 to pull the second T-block 302 to move and reset after the two disc-shaped insulator bodies 100 are disassembled. This arrangement enables the second T-block 302 to be reset manually without the need to manually reset after the two disc-shaped insulator bodies 100 are separated, thereby reducing the complexity of the operation.

[0029] In one embodiment, if Figure 8 As shown, four side blocks 500 distributed in a circle are fixed to the bottom of the outer side wall of the docking tube 102, a second limiting column 501 is fixed to the bottom surface of the second rack 107, the second limiting column 501 is movably connected to the side block 500, and a second spring 502 is arranged on the periphery of the second limiting column 501. The arrangement of the second spring 502 allows the pull on the trapezoidal frame 401 to be released when the first arc-shaped rack 404 is opposite to the second arc-shaped rack 408, so that the trapezoidal frame 401 can move upward under the push of the second spring 502, and the first arc-shaped rack 404 is meshed with the second arc-shaped rack 408, so as to facilitate the final limitation of the position of the trapezoidal frame 401.

[0030] In one embodiment, if Figure 4 As shown, a positioning column 305 is fixed to the top surface of the resistance block 304, and the top of the positioning column 305 is movably connected to the fixed frame 300. The setting of the positioning column 305 enables the resistance block 304 to always move in the vertical direction when moving, thereby avoiding the resistance block 304 from moving in the horizontal direction, causing the resistance block 304 to be unable to contact the second rack 107.

[0031] In one embodiment, if Figure 7 and Figure 8As shown, a first T-block 201 is fixed to the inner wall of the fixing ring 200, a first T-slot 202 is provided on the side of the second rack 107 away from the tooth surface, the first T-block 201 is movably engaged in the first T-slot 202, and the arrangement of the first T-slot 202 and the first T-block 201 enables the position of the second rack 107 to be movably limited, thereby facilitating the movement of the second rack 107.

[0032] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
