Description

Technical Field

[0001] The utility model relates to the field of flat energy-saving wire clamps, in particular to a flat energy-saving wire clamp that is easy to install. Background Art

[0002] The flat energy-saving wire clamp is a connection device widely used in power systems. It has the characteristics of energy saving, high efficiency and reliability. The flat energy-saving wire clamp is mainly used for connecting power conductors, especially for power conductors with specifications of 35-240mm² and connecting electrical equipment with terminal board holes of 45mm.

[0003] After searching, a utility model flat energy-saving wire clamp with publication number CN220510265U is found, which includes a wire clamping part and a connecting part. The wire clamping part includes a lower clamping plate and an upper clamping plate. One end of the lower clamping plate is connected to the connecting part. The upper clamping plate is provided with a kit, which is sleeved on the connecting part. Corresponding through holes are provided on the upper and lower clamping plates. The middle parts of the upper and lower clamping plates are both arc-shaped structures and are provided with a kit. During use and installation, the upper clamping plate is ensured to be always connected to the lower clamping plate. Even if the bolts in the through holes are taken out, there is no need to worry about the upper clamping plate falling or being lost.

[0004] The existing flat energy-saving wire clamp is a commonly used device for connecting power equipment and cables in power systems, and plays a very important role. The current common wire clamps are inconvenient to install and may become loose after installation, which poses certain safety hazards in the use of power equipment in the power system. At the same time, in the above-mentioned comparative case, the upper and lower clamps are installed by bolts, but the upper and lower clamps may become loose during the installation of the wires. When the wires are placed, the upper and lower clamps are in a separated state, so the staff needs to hold the wires down and then tighten the bolts to install and fix them. This operation is not only cumbersome, but also increases the labor intensity of the workers. This fails to meet the purpose of easy installation of the flat energy-saving wire clamp and reduces the stability of the installation effect.

[0005] Therefore, it is necessary to invent a flat energy-saving wire clamp that is easy to install to solve the above problems. Utility Model Content

[0006] The purpose of the utility model is to provide a flat energy-saving wire clamp that is easy to install. The installation groove opened on the surface of the installation plate is set as a rectangular groove, which can be convenient for installation according to different positions. Thereafter, the torsion spring is placed between the first claw block and the second gripping block, and the movable rod is passed through the two and the torsion spring. This is not only convenient and quick to install, but also the upper clamping plate and the lower clamping plate squeezed together by the rebound action of the torsion spring are combined, so that the wire is limited between the upper clamping plate and the lower clamping plate, avoiding the loosening of the wire during the screw tightening process, which is inconvenient for installation, so as to solve the problems raised in the above-mentioned background technology.

[0007] In order to achieve the above-mentioned object, the present utility model provides the following technical solutions: a flat energy-saving wire clamp that is easy to install, comprising a mounting plate for installing the flat energy-saving wire clamp;

[0008] A lower clamping plate is installed on one side of the mounting plate and is used to place the wires. The inner surface of the mounting plate is provided with a mounting groove. A boss is fixedly installed on the upper side of the lower clamping plate. Threaded holes are opened on both sides of the inner surface of the lower clamping plate.

The upper splint is fixedly installed on one side of the second gripping block. The inner two side surfaces of the upper splint are provided with threaded grooves. A screw rod passes through the inside of the lower splint and the upper splint. A gasket is provided on the outer sleeve of the screw rod. The outer side of the screw rod is movably connected to the second nut.

[0010] The pressure mechanism is installed on both sides of the upper clamping plate and is used to clamp the wires.

[0011] Preferably, the installation groove is configured as a rectangular groove, and the size of the interior of the installation groove matches the size of the bolt.

[0012] Preferably, the torsion spring is arranged between the first claw block and the second gripping block, an external thread is provided on the outside of one end of the movable rod, and a first nut is movably connected to one end of the movable rod.

[0013] Preferably, a wire placing groove is provided inside the upper clamping plate, a first anti-sliding block is provided on the surface of the wire placing groove, and an inner groove is provided inside the upper clamping plate.

[0014] Preferably, the pressure mechanism includes a fixed sleeve, an extrusion spring, a fixed block, a connecting rod, a pressure block, and a second anti-sliding block.

When the upper clamping plate is combined with the lower clamping plate, the internal pressure block will be clamped outside the wire. The connecting rod above the pressure block and the extrusion spring inside the fixed sleeve are used to rebound and squeeze the pressure block to the outside of the wire, thereby improving the clamping performance and avoiding loosening of the wire.

[0027] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0028] The utility model provides Figure 1-5 The flat energy-saving wire clamp shown is easy to install and includes a mounting plate 1 for installing the flat energy-saving wire clamp;

[0029] The lower clamping plate 3 is installed on one side of the mounting plate 1 and is used to place the wires. The inner surface of the mounting plate 1 is provided with a mounting groove 2. A boss 4 is fixedly installed on the upper side of the lower clamping plate 3. Threaded holes 5 are opened on both sides of the inner surface of the lower clamping plate 3. A first claw block 6 is fixedly installed on one side of the lower clamping plate 3.

[0030] The movable rod 7 runs through the inside of the first claw block 6 and is used to install and connect the upper splint 13. The outer sleeve of the movable rod 7 is provided with a torsion spring 8. The outer sleeve of the movable rod 7 is provided with a second gripping block 11. The inner surface of the second gripping block 11 is provided with a hole groove 12. The upper splint 13 is fixedly installed on one side of the second gripping block 11. The inner two sides of the upper splint 13 are provided with threaded grooves 14. The lower splint 3 and the upper splint 13 are penetrated by a screw 18. The outer sleeve of the screw 18 is provided with a gasket 19. The outer part of the screw 18 is movably connected to the second nut 20.

[0031] The pressure-applying mechanism 17 is installed on both sides of the upper clamping plate 13 and is used to clamp the wire. The installation groove 2 opened on the surface of the installation plate 1 is set as a rectangular groove, which can be convenient for installation according to different positions. Then the torsion spring 8 is placed between the first claw block 6 and the second gripping block 11, and the movable rod 7 is passed through the two and the torsion spring 8. This is not only convenient and quick to install, but also the upper clamping plate 13 and the lower clamping plate 3 squeezed by the rebound action of the torsion spring 8 are merged together, so that the wire is limited between the upper clamping plate 13 and the lower clamping plate 3, avoiding the loosening of the wire during the process of tightening the screw 18, which is inconvenient for installation.

[0032] like Figure 1 and Figure 2As shown, the mounting groove 2 is set as a rectangular groove, the size of the interior of the mounting groove 2 matches the size of the bolt, and the mounting groove 2 opened on the surface of the mounting plate 1 is set as a rectangular groove, which can be easily installed according to different positions.

[0033] like Figure 1 、 Figure 2 and Figure 3 As shown, the torsion spring 8 is arranged between the first claw block 6 and the second gripping block 11, an external thread 9 is provided on the outside of one end of the movable rod 7, and a first nut 10 is movably connected to one end of the movable rod 7. The setting of the torsion spring 8 and the movable rod 7 plays a rebound role in driving the upper splint 13 and the lower splint 3 to merge and squeeze, thereby improving the stability of the installation.

[0034] like Figure 3 As shown, a wire-releasing groove is provided inside the upper clamping plate 13, and a first anti-sliding block 15 is provided on the surface of the wire-releasing groove. An inner groove 16 is opened inside the upper clamping plate 13. Multiple first anti-sliding blocks 15 are provided at the wire-clamping position inside the upper clamping plate 13 to clamp the wire, thereby increasing the friction with the wire.

[0035] like Figure 3 and Figure 4 As shown, the pressure mechanism 17 includes a fixed sleeve 1701, an extrusion spring 1702, a fixed block 1703, a connecting rod 1704, a pressure block 1705, and a second anti-slid block 1706.

Through the setting of the torsion spring 8 and the movable rod 7, the rebound drives the upper splint 13 and the lower splint 3 to be squeezed together, thereby improving the stability of the installation. Next, the mounting plate 1 is placed at the position where the wire needs to be clamped, and the mounting plate 1 is fixed by a threaded connection. After that, the upper splint 13 is flipped open on the lower splint 3, and then the wire is placed in the lower splint 3, and then the upper splint 13 is loosened, and the movable rod is opened. 7 The torsion spring 8 on the outside presses the wire inside the lower clamp 3 by torsion rebound action, and when the upper clamp 13 is combined with the lower clamp 3, the internal pressure block 1705 will be clamped outside the wire, and the connecting rod 1704 above the pressure block 1705 and the extrusion spring 1702 inside the fixed sleeve 1701 are used to rebound and squeeze the pressure block 1705 to press the outside of the wire, thereby improving the clamping performance and avoiding the loosening of the wire. Finally, the screw 18 is passed through the threaded hole 5 and the thread groove 14 in the lower clamp 3 and the upper clamp 13, and then the gasket 19 is put on the outside of the screw 18, and then the second nut 20 is tightened on the outside of the screw 18.
