DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] In order to have a clearer understanding of the technical features, objectives, and effects of the present utility model, the specific embodiments of the present utility model will now be described with reference to the accompanying drawings.

[0024] Embodiment 1

[0025] As Figures 1-4 shown, the utility model provides a technical solution: a polymer alloy bridge capable of withstanding the impact of short-circuit current, including a bridge 1, a cover plate 2 arranged on the upper part of the bridge 1, and a connection component 3 arranged under the cover plate 2. The connection component 3 includes a disassembly and assembly mechanism 31 arranged under the cover plate 2, and a fixing mechanism 32 is arranged inside the bridge 1. The disassembly and assembly mechanism 31 includes a mounting column 311 fixedly installed on the inner wall of the bridge 1. A convex groove 312 is opened on the upper part of the mounting column 311. A convex column 313 is slidably connected to the inner wall of the convex groove 312. A clamping groove 314 is opened on one side of the convex column 313. A first inner groove 315 is opened inside the bridge 1. An installation block 316 is slidably connected to the inner wall of the first inner groove 315. A clamping rod 317 is fixedly connected to one side of the installation block 316. One side of the bridge 1 is movably connected with a connecting rod 318. A first spring 319 is fixedly connected to the inner wall of the first inner groove 315. The outer end of the connecting rod 318 is rotatably connected with a rotating rod 3110 through a bearing. A positioning rod 3111 is fixedly connected to the inner side of the rotating rod 3110. A positioning hole 3112 is opened on the outer wall of the bridge 1. A limiting groove 3113 is opened on the outer wall of the bridge 1.

[0026] In this embodiment, the upper part of the convex column 313 is fixedly connected to the cover plate 2. The clamping rod 317 movably penetrates through the bridge 1, the mounting column 311 and is clamped with the clamping groove 314. One end of the first spring 319 is fixedly connected to the installation block 316. The inner end of the connecting rod 318 is fixedly connected to the installation block 316. Through the cooperation of the mounting column 311, the convex groove 312, the convex column 313, the installation block 316, the clamping rod 317, the connecting rod 318, and the first spring 319, it is convenient for manual fixation of the cover plate 2, the cover plate 2 can be made more stable during use, and at the same time, it is convenient to disassemble the cover plate 2, so as to facilitate subsequent inspection and maintenance of the cables inside the bridge 1.

[0027] Furthermore, the positioning rod 3111 is slidably connected in the positioning hole 3112, and the positioning rod 3111 is adapted to the limiting groove 3113. Through the cooperation of the positioning rod 3111, the positioning hole 3112, and the limiting groove 3113, the clamping rod 317 can be made to stay at a position away from the clamping groove 314, so that the hands of the operator can be freed, and thus it is more convenient for the operator to disassemble and assemble the cover plate 2.

[0028] When it is necessary to fix the cover plate 2, first, manually pull the rotating rod 3110 outward to drive the connecting rod 318 to move outward, so that the mounting block 316 fixedly connected to the inner end of the connecting rod 318 can move outward, and then the clamping rod 317 fixedly connected to one side of the mounting block 316 can move outward. And when the rotating rod 3110 moves outward, the positioning rod 3111 can move outward synchronously. When the positioning rod 3111 moves outward and separates from the positioning hole 3112, at this time, the clamping rod 317 moves away from the convex groove 312. Then, manually rotate the rotating rod 3110 to drive the positioning rod 3111 to rotate, and engage the positioning rod 3111 with the limiting groove 3113. Under the action of the elastic force of the first spring 319, the clamping rod 317 can stay at a position away from the convex groove 312, and there is no need for manual support of the rotating rod 3110 all the time. Then, manually fit the convex column 313 fixedly connected to the bottom of the cover plate 2 with the convex groove 312, and then push the cover plate 2. When the cover plate 2 is fitted with the bridge 1, manually separate the positioning rod 3111 from the limiting groove 3113 and fit the positioning rod 3111 with the positioning hole 3112. Then, under the action of the elastic force of the first spring 319, the mounting block 316 can drive the clamping rod 317 to move inward, so that the clamping rod 317 can be engaged with the clamping groove 314, and the fixing effect on the cover plate 2 can be achieved.

[0029] Embodiment 2

[0030] On the basis of Embodiment 1, a preferred embodiment of a polymer alloy bridge capable of withstanding the impact of short-circuit current provided by the present utility model is as Figures 1 to 4 shown: The fixing mechanism 32 includes a limiting support bar 321 fixedly connected to the inner wall of the bridge 1. A plugging strip 322 is slidably connected to the inner wall of the limiting support bar 321. An impact-resistant dividing longitudinal bar 326 is fixedly connected to the upper part of the plugging strip 322. A pressing groove 327 is formed on the side wall of the impact-resistant dividing longitudinal bar 326. A second inner groove 323 is formed inside the limiting support bar 321. A pressing block 324 is sleeved inside the second inner groove 323. A second spring 325 is fixedly connected to the inner wall of the second inner groove 323.

[0031] In this embodiment, one end of the second spring 325 is fixedly connected to the pressing block 324, and the pressing block 324 is adapted to the pressing groove 327. Through the cooperation of the limiting support bar 321, the plugging strip 322, and the impact-resistant dividing longitudinal bar 326, the overall quality of the bridge 1 to withstand the impact of short-circuit current is improved, and the effect of being conducive to adaptively installing a separation structure according to application requirements is achieved. At the same time, through the cooperation of the pressing block 324, the pressing groove 327, and the second spring 325, a fixing effect can be exerted on the impact-resistant dividing longitudinal bar 326, so that the impact-resistant dividing longitudinal bar 326 can be more stable during use.

[0032] Further, there are several limiting support strips 321, which are grouped in pairs and symmetrically distributed on both sides of the plug-in plug strip 322.

[0033] When fixing the impact-resistant partition vertical strip 326, it is only necessary to manually insert the plug-in plug strip 322 fixedly connected to the bottom of the impact-resistant partition vertical strip 326 into the limiting support strip 321. When the plug-in plug strip 322 is fully engaged with the limiting support strip 321, under the action of the elastic force of the first spring 319, the pressing block 324 can be pressed outwards, so that the pressing block 324 can be engaged with the pressing groove 327, thereby achieving a fixing effect on the impact-resistant partition vertical strip 326, and further making the impact-resistant partition vertical strip 326 more stable during use.
