Description

Technical Field

[0001] This utility model relates to the field of tension connecting plate technology, specifically to an adjustable tension connecting plate. Background Technology

[0002] Tension connecting plates are a type of connecting hardware in electrical fittings, mainly used for connecting conductors to conductors on overhead lines. They are used for the parallel installation of double and multi-strand tension insulator strings, the assembly of insulator strings with two or more conductors, and the assembly of double guy wires. A search revealed an existing technology (publication number: CN201921340493.8) of an adjustable tension connecting plate, which describes how "different splitting spacings and splitting numbers can be obtained by installing the mounting bolts in different positions of the installation adjustment holes, reducing construction work and saving costs; at the same time, the first and second small plates are welded to the back of the large circular plate to reinforce it." However, the existing technology has multiple fixed installation adjustment holes, resulting in limited adjustability of the tension connecting plate. Utility Model Content

[0003] To overcome the shortcomings of existing technologies, an adjustable tension connecting plate is provided to solve the problem that the adjustability of the tension connecting plate is limited because the multiple installation adjustment holes in the existing technology are all fixed.

[0004] To achieve the above objectives, an adjustable tension bracing plate is provided, comprising: a tension bracing plate body, wherein a first mounting hole is formed on the surface of the tension bracing plate body.

[0005] The tension connecting plate is symmetrically fitted with an adjusting left plate and an adjusting right plate on its left and right sides. The adjusting right plate is fixed to the adjusting left plate by fastening bolts. The surfaces of the adjusting left and right plates are provided with second mounting holes. Limiting posts are embedded and welded to the inner sides of the adjusting left and right plates. The limiting posts are movably connected to the tension connecting plate through limiting grooves. A U-shaped rib is welded to the middle of the tension connecting plate. The left and right sides of the U-shaped rib are connected to the adjusting left and right plates through limiting studs.

[0006] Furthermore, the tension-resistant connecting plate has two sets of limiting grooves on its surface, with limiting holes penetrating through the limiting grooves; and the limiting grooves are symmetrically located on the left and right sides of the U-shaped rib.

[0007] Furthermore, the first mounting holes are located at the upper end of the U-shaped rib, and a fixing head is welded to the cylindrical surface of the other end of the limiting stud.

[0008] Furthermore, the lower end plates of the left and right adjustment plates are provided with through grooves; and limit studs pass through the through grooves, with positioning nuts screwed onto the surface of the limit studs.

[0009] Furthermore, the front and rear side plates of the U-shaped rib are provided with connecting holes, and the front and rear surfaces of the adjusting left plate and the adjusting right plate are welded with extension plates.

[0010] Furthermore, the extension plate is connected to the connecting holes on the surface of the U-shaped rib plate by fastening bolts.

[0011] Furthermore, two sets of second mounting holes are equidistantly distributed on the outer end of the limiting hole post; and a cylindrical cavity is provided on the inner side of the limiting hole post.

[0012] The beneficial effects of this utility model are that the adjustable tension connecting plate is movably connected to the tension connecting plate body groove by the limiting holes on the inner sides of the adjusting left plate and the adjusting right plate. By moving left and right, the limiting holes and the second mounting holes on the surfaces of the adjusting left plate and the adjusting right plate are respectively located on the inner and outer sides of the tension connecting plate body, which facilitates more flexible adjustment of the mounting hole position on the tension connecting plate surface, effectively enhances the adjustment effect of the mounting hole position of the tension connecting plate, and at the same time increases the length of the tension connecting plate itself, improving the practicality of the adjustable tension connecting plate.

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Reference Figures 1 to 4 As shown, this utility model provides an adjustable tension connecting plate, including: a tension connecting plate body 1, with a first mounting hole 11 on the surface of the tension connecting plate body 1.

[0020] The left and right sides of the tension connecting plate 1 are symmetrically fitted with an adjusting left plate 2 and an adjusting right plate 3. The right adjusting plate 3 is fixed to the left adjusting plate 2 by fastening bolts 31. The surfaces of the left adjusting plate 2 and the right adjusting plate 3 are provided with second mounting holes 23. Limiting hole columns 21 are embedded and welded to the inside of the left adjusting plate 2 and the right adjusting plate 3. The limiting hole columns 21 are movably connected to the tension connecting plate 1 through limiting grooves 12. A U-shaped rib plate 4 is welded to the middle of the tension connecting plate 1. The left and right sides of the U-shaped rib plate 4 are connected to the left adjusting plate 2 and the right adjusting plate 3 by limiting studs 41.

[0021] When it is necessary to adjust the mounting hole position on the surface of the tension connecting plate, move the left adjusting plate 2 and the right adjusting plate 3 outwards, so that the second mounting hole 23 on the surface of the left adjusting plate 2 and the right adjusting plate 3 moves to the outer end of the tension connecting plate body 1. After the limiting hole post 21 moves along the limiting groove 12 to the appropriate installation position, rotate the positioning nut 44 on the surface of the limiting stud 41 so that the positioning nut 44 positions the left adjusting plate 2 and the right adjusting plate 3 in this position. Then, use the fastening bolt 31 to connect and fix the left adjusting plate 2 and the right adjusting plate 3 to adjust the mounting hole position on the surface of the tension connecting plate. Then, use the connecting plate clamp to connect with the wire.

[0022] In this embodiment, the tension plate 1 has two sets of limiting grooves 12 on its surface, with limiting holes 21 passing through the limiting grooves 12; and the limiting grooves 12 are symmetrically located on the left and right sides of the U-shaped rib 4. The first mounting holes 11 are located at the upper end of the U-shaped rib 4, and a fixing head 42 is welded to the other end of the limiting stud 41.

[0023] As a preferred embodiment, the fixed column head 42 facilitates the restriction of the left and right adjustment plates 2 and 3 from moving off the surface of the limiting stud 41. The fastening bolt 31 facilitates the reinforcement of the connection between the left and right adjustment plates 2 and 3, ensuring that the left and right adjustment plates 2 and 3 are stably fixed on both sides of the tension connecting plate 1 after adjustment.

[0024] In this embodiment, the lower end surfaces of the left and right adjustment plates 2 and 3 are provided with through grooves 24; and limit studs 41 pass through the through grooves 24, with positioning nuts 44 screwed onto the surface of the limit studs 41. Connecting holes 43 are provided on the front and rear side surfaces of the U-shaped rib plate 4, and extension plates 22 are welded to the front and rear surfaces of the left and right adjustment plates 2 and 3. The extension plates 22 are connected to the connecting holes 43 on the surface of the U-shaped rib plate 4 through fastening bolts 31.

[0025] As a preferred embodiment, two sets of positioning nuts 44 are screwed onto the surface of the limiting stud 41, and the two sets of positioning nuts 44 are respectively located on the left and right sides of the lower end plate of the left adjustment plate 2 and the right adjustment plate 3, so as to facilitate positioning the adjusted position of the left adjustment plate 2 and the right adjustment plate 3.

[0026] In this embodiment, two sets of second mounting holes 23 are equidistantly distributed on the outer end of the limiting hole post 21; and a cylindrical cavity is provided on the inner side of the limiting hole post 21.

[0027] In a preferred embodiment, the second mounting hole 23 can be moved to the outer end of the tension connecting plate 1 to facilitate expanding the adjustment range of the mounting hole position. The cylindrical cavity inside the limiting hole post 21 matches the diameter of the second mounting hole 23, which can serve as a mounting function. At the same time, the limiting hole post 21 limits the connection of the left adjusting plate 2 and the right adjusting plate 3 within the groove of the tension connecting plate 1, preventing them from separating.

[0028] The adjustable tension connecting plate of this utility model can effectively solve the problem that the adjustment of the tension connecting plate is limited because the multiple installation adjustment holes in the prior art are all fixed holes. It makes it easier to adjust the position of the installation holes on the tension connecting plate more flexibly, effectively enhances the adjustment effect of the installation hole position of the tension connecting plate, and at the same time increases the length of the tension connecting plate itself, improving the practicality of the adjustable tension connecting plate. It is suitable for adjustable tension connecting plates.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
