Description

Technical Field

[0001] This utility model relates to the field of insulator technology, and in particular to a crossarm insulator. Background Technology

[0002] A crossarm insulator is an insulating device used in power systems, primarily providing electrical insulation and mechanical support between the conductor and the supporting structure. Existing crossarm insulators have a through hole on their metal base for connecting to the crossarm (which has pre-drilled through holes), and a positioning hole on one side of the through hole. This prevents significant wind deflection of the crossarm insulator. However, during construction, some workers fail to drill the positioning hole on the crossarm, making it impossible to install the positioning bolts, resulting in wind deflection of the crossarm insulator after the line is put into operation. To solve this problem, patent application number 202111046884.0 discloses a crossarm insulator reinforcement device; however, this device has a relatively complex structure and requires additional installation. This application provides a crossarm insulator that does not require drilling positioning holes on the crossarm. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a crossarm insulator in response to the above-mentioned technical deficiencies.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a crossarm insulator, including an insulator, with a metal base and a fixing seat respectively provided at both ends of the insulator, a through hole provided on the metal base, side arms provided on both sides of the metal base, and an inclined leg provided at the end of the side arm away from the metal base, the inclined leg being inclined outward in the direction from near to far from the metal base, and a first threaded hole provided on the side of the through hole away from the side arm on the metal base, the first threaded hole being threadedly connected to a leveling bolt.

[0005] To further optimize this technical solution, the metal base is provided with a cavity running through both sides.

[0006] To further optimize this technical solution, a groove is provided on the side of the fixing seat away from the insulator.

[0007] To further optimize this technical solution, the fixing base is provided with second threaded holes on both sides of the groove, and also includes a clamping plate that is detachably connected to the fixing base. Both sides of the clamping plate are provided with through holes, and the fastening bolts pass through the through holes and connect to the second threaded holes.

[0008] Compared with the prior art, the present invention has the following advantages: both sides of the metal base are provided with side arms and the end of the side arm away from the metal base is provided with an inclined leg. The first threaded hole on the metal base on the side away from the side arm is threaded with a leveling bolt, so that it is not necessary to open a positioning hole on the crossarm to prevent the crossarm insulator from deflecting due to wind.

[0013] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0014] Detailed implementation method: combined with Figure 1-3 As shown, a crossarm insulator includes an insulator 2 with sheds on its exterior. A metal base 1 and a fixing seat 3 are respectively provided at both ends of the insulator 2. The metal base 1 is used to connect to the crossarm 5, and the fixing seat 3 is used to fix the wire. The metal base 1 has a through hole 11. Side arms 14 are provided on both sides of the metal base 1. An inclined leg 141 is provided at the end of each side arm 14 away from the metal base 1. The inclined leg 141 slopes outward from the direction closest to the metal base 1. The minimum distance between the two inclined legs 141 is less than the width of the crossarm 5, and the maximum distance between the two inclined legs 141 is greater than the width of the crossarm 5. A first threaded hole 12 is provided on the side of the through hole 11 away from the side arm 14 on the metal base 1. A leveling bolt 13 is threadedly connected to the first threaded hole 12. During installation, combined with... Figure 1As shown, the two inclined legs 141 are located on both sides of the crossarm 5. The bolts pass through the through hole 11 and the through hole on the crossarm 5 and are connected to the nuts. After tightening the nuts, the inner sides of the two inclined legs 141 contact the two sides of the crossarm 5 respectively, so that the crossarm insulator will not be deflected by wind. If the angle between the metal base 1 and the crossarm 5 is large at this time (due to the presence of the inclined legs 141, the metal base 1 is not in contact with the crossarm 5, so that there is an angle between the metal base 1 and the crossarm 5), causing the crossarm insulator to be significantly skewed, the nuts can be loosened slightly, and then the leveling bolts 13 can be tightened to make the crossarm insulator no longer skewed, and then the nuts are tightened.

[0015] Furthermore, the metal base 1 is provided with cavities running through both sides, which reduces weight, saves materials, and lowers costs.

[0016] Furthermore, the fixing base 3 has a groove on the side away from the insulator 2, and the wire can be inserted into the groove.

[0017] Furthermore, the fixing base 3 is provided with second threaded holes 31 on both sides of the groove, and also includes a clamping plate 4 that is detachably connected to the fixing base 3. The clamping plate 4 is provided with through holes on both sides. After the fastening bolt passes through the through holes, it connects to the second threaded holes 31, thereby fixing the wire.

[0018] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
