Technical Field

[0001] The utility model relates to the technical field of hardware strings, in particular to a compact, lightweight, tension-resistant hardware string. Background Art

[0002] Hardware is an iron or aluminum metal accessory widely used in transmission lines. It can connect and suspend insulator strings. There are many types of hardware with different uses, such as various wire clamps for installing conductors, various hanging rings for forming insulator strings, various crimping tubes and repair tubes for connecting conductors, various types of spacers for split conductors, etc. In addition, there are various types of wire pulling hardware for poles and towers, as well as hardware used to protect conductors. They are related to the size and must be coordinated with each other.

[0003] A common compact and lightweight tension fitting string consists of a U-shaped ring, an extension ring, a connecting plate, and an insulator string. The extension ring is fully enclosed, and the user cannot increase the number of extension rings according to the installation conditions, which limits the use environment. In addition, the connecting plate is a fixed plate structure and cannot be adjusted. It is not convenient to adjust the distance between the two insulators according to usage needs, and its practicality is insufficient. Therefore, we propose a compact and lightweight tension fitting string. Utility Model Content

[0036] Example 2

[0037] like Figure 1-4 As shown, the forward and reverse screw rods 102 are rotatably connected to the fixing seat 101, and the slider 103 is adapted to the forward and reverse screw rods 102. By adapting the slider 103 to the forward and reverse screw rods 102, the forward and reverse screw rods 102 can be rotated to drive the slider 103 to move inward or outward at the same time, thereby achieving the purpose of adjusting the installation spacing of the insulator string. A built-in groove 105 is provided inside the fixing seat 101 and on the periphery of the forward and reverse screw rods 102. The opening of the built-in groove 105 can reduce the weight of the fixing seat 101, thereby achieving the purpose of lightweighting. A slide groove 106 is provided on the front and on the periphery of the slider 103. The slider 103 is slidably connected to the slide groove 106. The sliding connection between the slider 103 and the slide groove 106 can limit the moving slider 103 to prevent it from spirally rotating with the positive and negative screw rods 102, thereby improving the stability of use. The T-shaped connector 104 is welded to the slider 103. The top of the T-shaped connector 104 passes through the bottom and is provided with a circular groove for connecting the insulator string. By welding the T-shaped connector 104 to the slider 103, the T-shaped connector 104 can be made more firm, and the circular groove is opened. The T-shaped connector 104 is convenient for connecting to the insulator string. The threaded column 202 is welded to the C-shaped ring 201. The connecting nut 203 is adapted to the threaded column 202. Through the design of the C-shaped ring 201, the staff can connect and use multiple C-shaped rings 201 according to construction requirements, thereby improving practicality. The connecting nut 203 can be rotated by adapting the connecting nut 203 to the threaded column 202, thereby achieving the closure of the C-shaped ring 201 and preventing the U-shaped ring 204 from detaching therefrom, thereby improving the stability of use. The threaded rod 205 is respectively connected to the fixing seat 101 and the U-shaped ring 204 Adaptation, the fixing nut 206 is adapted to the threaded rod 205, and the fixing seat 101 and the U-shaped ring 204 can be fixed by rotating the threaded rod 205. The fixing nut 206 can prevent the threaded rod 205 from falling off, thereby improving the connection strength. A slot 2051 is provided on the periphery of the threaded rod 205 and at the bottom of the fixing nut 206, and a pin 2052 is installed inside the slot 2051. By inserting the pin 2052 into the slot 2051, the fixing nut 206 can be limited to prevent the fixing nut 206 from loosening and falling off, thereby improving the stability of use.

[0038] The working process of the present invention is as follows: when adjusting the installation spacing of an insulator string for a compact and lightweight tension-resistant hardware string, first use bolts to fix the insulator string and the T-shaped connector 104, and rotate the positive and negative screw rods 102 according to actual installation requirements, so that it drives the T-shaped connector 104 to move synchronously inward or outward through the slider 103, thereby achieving the purpose of adjusting the installation spacing of the insulator string. The operation is very convenient and effectively improves practicality. When the installation environment requires a longer hardware component 2, first rotate the connecting nut 203 to disengage it from one of the threaded columns 202, and remove one of the U-shaped rings 204 from the C-shaped ring 201 interface, open the other C-shaped ring 201 in the same way, and put the removed U-shaped ring 204 into it, and finally hook the two C-shaped rings 201 together, and rotate the connecting nut 203 to close all the C-shaped rings 201, to complete the extension of the hardware component 2, which can be extended according to the actual use environment, effectively avoiding the disadvantages brought by traditional extension rings.
