Embodiment 1

[0026] Embodiment 1: see figure 1 The shown is a portable screen-top copper bar busbar cutting tool, which is applied to the cutting of copper bar busbars. The T-shaped direct push plate is pushed forward in a straight line to ensure a smooth cutting section, and the swing range of the hand levers on both sides is relatively large. Ensure labor-saving and efficient cutting. The arc-shaped pull rod at the front end of the tool is a closed structure, which forms a closed cutting space when used in combination with the T-shaped straight push plate, so as to ensure that the copper bar busbar will not slip and hard section flatness factors will not appear during the cutting process.

[0027] Such as figure 1 As shown in the structure of the tool, pin shaft holes are respectively arranged on the lower parts of both sides of the base and pin shafts A and A' are installed, and the upper ends of the two swing rods are respectively hinged on the pin shafts A and A'. Specifically, the ...

Embodiment 2

[0034] Embodiment 2: On the basis of Embodiment 1, the design adopts the arc-shaped pull rod on each side as Figure 8 In the structure shown in the figure, it can be seen that each side of the arc-shaped tie rods includes two parallel arc-shaped plates, the upper ends of each side of the arc-shaped tie rods are hinged together through the central shaft, and the lower ends of each side of the arc-shaped tie rods are respectively provided with holes. Pin shafts D and D' are installed, so that the arc-shaped pull rods on both sides are hinged together to form a semi-closed structure. The area between the two arc-shaped plates of the arc-shaped pull rods on each side is a relief groove, and the knife seat is matched and clamped in the middle relief groove and can slide.

Embodiment 3

[0035] Embodiment 3: When the embodiment cuts the copper rod busbar by the T-type direct push plate, when the design is that the T-type direct push plate moves to the end limit position, when the arc cutter of the T-type direct push plate approaches the central axis, The bus bar of the copper rod is cut off, that is, it only needs to control the inward compression of the hand levers on both sides to the limit position each time. However, this embodiment is based on Embodiment 1, and further fixes or covers the inherent restraint stoppers on the outside of the arc-shaped pull rods on both sides. , the restraining block can be supported on the upper surface of the base to prevent the arc-shaped pull rod from continuing to descend. The design purpose of this embodiment is to create a limit position by fixing or setting the inherent constraint stopper. Even if the handle bars on both sides are not compressed inward to the limit position, when the T-shaped straight push plate may m...

Abstract

The invention discloses a portable screen top copper bar bus bar cutting tool. The portable screen top copper bar bus bar cutting tool comprises a handle and a cutter; two swing rods are hinged to thetwo sides of the lower portion of a base through a pin shaft A and a pin shaft A' correspondingly, a straight push plate is sleeved with a vertical center hole of the base in a matched mode, a tool apron is arranged at the upper end of the straight push plate, an arc-shaped tool is fixedly clamped in the tool apron, a push seat is arranged at the lower end of the straight push plate, two obliqueswing rods are hinged to the two sides of the push seat through a pin shaft B and a pin shaft B' correspondingly, and the other ends of the two inclined swing rods are hinged to the middles of the swing rods on the two sides through a pin shaft C and a pin shaft C'. According to the portable screen top copper bar bus bar cutting tool, it is ensured that a small bus can be firmly wrapped and kept vertical without inclination all the time in the forced cutting process, the touch fault caused by inclination of the inner side or the outer side of the small bus is prevented, the labor-saving effectcan be achieved, and the operation is easy and convenient.

Description

technical field [0001] The invention belongs to the improvement technology of a spanning frame in the field of water conservancy and electric power, and in particular relates to a portable screen-top copper rod busbar cutting tool. Background technique [0002] The screen top line busbar is a small busbar on the top of the relay protection panel, usually a brass rod with a diameter of 6mm, which is divided into kma / kmc control small busbar DC, HMA / HMC closing small busbar DC, YMA / YMB / YMC voltage small busbar , SYM accident audio bus and ZMn lighting small bus, etc. It is a common accumulation line for control power supply, signal power supply, protection power supply, AC voltage, AC power supply, etc. Usually, it is connected to the top of the protection cabinet with copper rods, aluminum bars or cables to collect and distribute electric energy. It belongs to the ring The network power supply mode can save secondary cables and simplify the circuit. When the relay protectio...
