Description

A multifunctional secondary cable stripping knife

Technical field:

The invention relates to a multifunctional secondary cable stripping knife, which can be widely used in the stripping and cutting of various secondary control cable sheaths, lining layers, steel armor layers, copper shielding layers, fillings, etc. Appliance application field.

Background technique:

During the construction and renovation of substations, a large number of secondary control cables need to be laid, and the secondary equipment also needs to be connected through secondary cables. The secondary cables undertake the transmission of all information data and signal transmission of the substation. The most critical part of cable wiring is stripping. The speed and quality of stripping work greatly affect the progress and quality of the entire project. There are many wire stripping knives at present, but they will be restricted by various environmental conditions in actual work, which will cause damage to cables and reduce work efficiency.

The sheath of the secondary cable is hard, made of rubber material, especially in winter. It is difficult to grasp the running track of the traditional utility knife, which will easily cause the knife to slip, easily scratch the staff, and easily damage the control cable. Wire. Therefore improving the original cable stripping knife is an urgent problem to be solved.

Invention content:

The purpose of the present invention is to overcome the deficiencies of the above-mentioned prior art and provide a multifunctional secondary cable stripping knife with simple structure, various functions, not easy to fall off, convenient operation, safety and reliability, hard structure, reduced cable loss, and improved work efficiency. .

The object of the present invention can be achieved through the following measures: a multifunctional secondary cable stripping knife, which includes a knife handle and a knife head installed at the front end of the knife handle, is characterized in that the top of the knife head is provided with a pry blade, and the pry blade The shape of the blade is a steep slope type. A hook blade is provided below the upper prying blade of the cutter head. The blade of the hook blade is arc-shaped and bends downward. straight blade.

In order to further realize the purpose of the utility model, an insulating anti-slip sleeve is provided on the handle of the knife, and an arc-shaped groove is provided on the inner side of the insulating anti-slip sleeve.

Compared with the prior art, the present invention can produce the following positive effects: the utility model improves the stripping speed and quality of the cable, accelerates the overall speed of substation construction or transformation, reduces the loss of the cable during the construction process, and reduces the damage caused by core damage. The failure caused by the construction ensures the safety of the construction personnel, improves the work efficiency and the economic benefits of the enterprise. which has:

1. Simple structure and diverse functions. The invention is composed of prying blade, hook blade, cutting blade and handle. The structure is simple, small and compact. The three blades are integrated into one body. Different blades can be selected according to the situation during construction, so as to improve the speed and quality of cable stripping and improve the working efficiency. efficiency.

2. Not easy to fall off. When stripping the cable sheath, the present invention only needs to insert the hook blade into the cable sheath and apply force backwards. Since the construction personnel can better grasp the operation track and the stripping knife is not easy to slip, the safety of the construction personnel is guaranteed because no downward force is required. .

3. Easy to operate. Use the hook blade when stripping the outer sheath of the cable, just hook it a little and pull it back, and cut it off with the cutter blade after stripping to the required length, which is practical and easy to operate.

4. The structure is hard. Because often need to use stripping knife, because the present invention specially selects the all very high titanium-manganese alloy of strength and toughness, all blades all need sharpening, guarantee that this tool utensil is not easy to damage.

Description of drawings:

Fig. 1 is a structural schematic diagram of the present invention.

detailed description:

Below in conjunction with accompanying drawing, the embodiment of the present invention is described in detail:

Embodiment: a multifunctional secondary cable stripping knife (see Figure 1), which includes a handle 4 and a cutter head 5 installed at the front end of the handle 4, an insulating anti-slip sleeve is provided on the handle 4, and the inner side of the insulating anti-slip sleeve An arc-shaped groove 6 is provided to make it easier for the user to hold, not easy to disengage, and safe and reliable. The cutter head 5 is a titanium-manganese alloy cutter head. The top of the cutter head 5 is provided with a prying blade 1. The blade shape of the prying blade 1 is a steep slope type. The blade is arc-shaped and bends downward, and the inboard hook blade 2 of the cutter head 5 is provided with a cutting blade 3 below the hook blade 2, and the blade of the cutting blade 3 is a straight blade.

When the utility model is carrying out cable stripping:

1. Use the hook blade 2 to hook the cable sheath and pull it straight back.

2. Insert the blade 1 of the prying knife into the interior of the armor layer, and force upwards. Since the active area is small, it will be easy to pry the armor layer off.

3. Use the cutter blade 3 to cut off the cable sheath, copper shield, filling.
