Problems solved by technology

[0002] In today's society, it is very important to use electricity safely and ensure the safe and stable operation of the power grid. The poor connection of wires has brought a lot of trouble to people, and even has potential safety hazards.
The existing clamps are unevenly loaded on one side and easily deformed on one side. When the nut is tightened, it will slide to the left and right sides. It requires multiple adjustments to align, which increases the difficulty of operation; it cannot be self-locking, and the connection is not stable. Affected by thermal expansion and contraction, easy to loosen, short service life, frequent maintenance; small contact surface, requires professional tools, inconvenient installation, poor versatility

Embodiment 1

[0020] Such as figure 1 and figure 2 As shown, a multifunctional one-way cable clamp includes a clamp body 1, a groove 12 is provided in the clamp body 1, and a first movable chuck 3 that can move up and down is embedded in the groove 12 from top to bottom and the second movable chuck 4, the upper and lower ends of the first movable chuck 3 are provided with a structure for clamping, the upper end of the second movable chuck 4 is provided with a structure for clamping, and the top of the clamp body 1 is fixedly connected There is a static chuck 2 opposite to the first movable chuck 3, a bolt hole is provided under the clamp body 1, an adjusting bolt 5 passes through the bolt hole and is fixedly connected with the wire clamp body 1, and is connected with the second movable clamp The first 4 tops are connected. Wherein the static chuck 2 and the first moving chuck 3, the first moving chuck 3 and the second moving chuck 4 are the clamping parts, the static chuck 2 and the firs...

Embodiment 2

[0022] On the basis of embodiment 1, this embodiment has been improved as follows:

[0023] Wherein at least one side of the first movable chuck 3 is provided with a downwardly reversed anti-return sawtooth, and the outer side of the first movable chuck 3 is provided with an anti-loosening anti-reverse sawtooth sheet 6 that cooperates with it, at least A compression spring 7 is provided between the anti-loosening and anti-reversing sawtooth sheet 6 on one side and the clamp body 1, and the first movable chuck 3 and the anti-loosening and anti-reversing sawtooth sheet 6 are compressed by the compression spring 7. Wherein the compression spring 7 is a wave-shaped leaf spring or a columnar spring, and the columnar spring can be a cylindrical helical spring, preferably a leaf spring. The difference from Example 1 during disassembly is that the outer protective cover 8 needs to be disassembled first, the pressure spring 7 is taken out, the anti-loosening anti-reverse saw tooth piec...

Embodiment 3

[0025] On the basis of embodiment 1, this embodiment has been improved as follows:

[0026] Wherein at least one side of the second movable chuck 4 is provided with a downwardly reversed non-return sawtooth, and the outer side of the second movable chuck 4 is provided with an anti-loosening anti-reverse sawtooth sheet 6 that cooperates with it, at least A compression spring 7 is provided between the anti-loosening and anti-reversal sawtooth sheet 6 on one side and the clamp body 1, and the second movable chuck 4 and the anti-loosening and anti-reversal sawtooth sheet 6 are compressed by the compression spring 7. Wherein the compression spring 7 is a wave-shaped leaf spring or a columnar spring, and the columnar spring can be a cylindrical helical spring, preferably a leaf spring. The difference with embodiment 1 during disassembly is: the outer protective cover 8 needs to be disassembled first, the compression spring 7 is taken out, the anti-loosening anti-reverse saw tooth pi...

Abstract

The invention discloses a multifunctional one-way cable clamp. The clamp comprises a clamp body and is characterized in that a groove is arranged in the clamp body, a first movable chuck and a second movable chuck are embedded into the groove from top to bottom and can move up and down, clamping structures are arranged at two ends of the first movable chuck and at the upper end of the second movable chuck, a fixed chuck opposite to the first movable chuck is fixedly connected to the upper side of the clamp body, a bolt hole is arranged on the lower side of the clamp body, and an adjusting bolt penetrates through the bolt hole, is fixedly connected with the clamp body and abuts against the second movable chuck. The clamp is high in generality, capable of being suitable for various diameters of cables, simple in structure, reasonable in design, balanced in pressure, constant in clamping force, small in contact resistance, stable and reliable in connection and convenient and safe in use.

Description

technical field [0001] The invention relates to a cable clamp, in particular to a multifunctional one-way cable clamp. Background technique [0002] In today's society, it is very important to use electricity safely and ensure the safe and stable operation of the power grid. The poor handling of wire connections has brought a lot of trouble to people, and even has potential safety hazards. The existing clamps are unevenly loaded on one side and easily deformed on one side. When the nut is tightened, it will slide to the left and right sides. It requires multiple adjustments to align, which increases the difficulty of operation; it cannot be self-locking, and the connection is not stable. Affected by thermal expansion and contraction, it is easy to loosen, has a short service life and frequent maintenance; the contact surface is small, professional tools are required, installation is inconvenient, and the versatility is poor. Contents of the invention [0003] The task of ...
