Description

A humanized and convenient brake lever

technical field

The utility model belongs to the field of power tools, in particular to a humanized and convenient brake lever.

Background technique

The brake lever is also called an insulating operating rod, an insulating rod, and a high-voltage operating rod. The brake lever is an insulating tool used to operate live equipment for a short time, such as turning on or off the high-voltage isolating switch, dropping the fuse, etc. The operating head of the existing brake lever is mostly a T-shaped operating head, and the brake lever performs operations such as opening and closing the brake through the T-shaped operating head. However, when the T-shaped operating head is used for operation, the operating head and the parts to be operated often slip off, which affects the normal operation of the brake lever.

Utility model content

The purpose of the utility model is to overcome the above-mentioned defects of the prior art, and provide a humanized and convenient brake lever which can avoid slipping of the operating head and the parts to be operated.

The utility model is realized through the following technical scheme: a humanized and convenient brake lever, which includes an insulating rod and an operating head, the operating head includes a working head for opening a brake and a working head for closing a brake, and the working head for a brake is a curved opening with a downward opening. The hook, the closing working head is a curved hook with the opening downward, and the lower end of the operating head is connected to the upper end of the insulating rod. The insulating rod includes no less than two insulating rod units, and the insulating rod units are sequentially connected in series. Because the operating head includes a brake working head and a closing working head, the closing working head is a crotch with an opening downward, and the closing working head is a crotch with an opening downward. When the brake lever is used for the operation of opening and closing the brake, the hooks of the working head for closing the brake and the hook of the working head for closing the brake can well hook the parts to be operated, thereby preventing the operating head from slipping. Other structures of the present invention are common knowledge in the technical field, and will not be described in detail here.

Further, the lower end of the insulating rod unit is provided with a socket, and the upper end of the insulating rod unit is provided with a socket that is connected to the socket, and the socket and socket are connected by threads. Due to the threaded connection between the socket sleeve and the socket head, the connection operation between the insulating rod units is very simple. When the length of the insulating rod needs to be lengthened, the insulating unit can be assembled conveniently to form a new insulating rod.

Further, an umbrella is sheathed on the outer periphery of the receiving sleeve. When using the switch rod to carry out live operation on open-air high-voltage equipment in thunderstorm days, the existence of rainwater often has a serious impact on the insulation performance of the switch rod, which can easily lead to safety accidents. By covering the outer periphery of the connecting sleeve with an umbrella, it is possible to prevent rainwater from sliding down to the lower end of the switch rod, effectively protect the insulation performance of the switch rod, and avoid the occurrence of safety accidents due to the decline in the insulation performance of the switch rod.

Further, the material of the umbrella is silicone rubber. First of all, silicone rubber has good resistance to atmospheric oxidation, and has excellent heat resistance and cold resistance, and can be used for a long time at -60°C to +250°C. Therefore, the use of silicone rubber to make umbrellas can prolong the life of umbrellas. service life. Secondly, silicone rubber has good insulation properties and can isolate current well. Finally, silicone rubber has a certain degree of flexibility, and the umbrella made of silicone rubber can be well fixed on the outer periphery of the sleeve without falling off.

Further, an insulating anti-slip sheath is also included, the lower end of the insulating rod is connected to the insulating anti-slip sheath, and finger grooves are provided on the outer periphery of the insulating anti-slip sheath. In actual use, it is often necessary to use longer insulating rods. Due to the long length of the insulating rod, it is particularly easy to slip from the hand during use, and the slipping of the insulating rod often poses a huge threat to the safety of the operator. By connecting the insulating non-slip sheath to the lower end of the insulating rod, when in use, the finger holds the finger groove on the outer periphery of the insulating non-slip sheath, which can enhance the stability of the insulating rod and ensure that the insulating rod will not break out from the hands of the operator. Slip and fall, to ensure the life safety of the operator.

Further, the inside of the insulating rod is hollow. By adopting the hollow insulating rod, the weight of the shutter rod can be greatly reduced without changing the working performance of the shutter rod. Due to the considerable weight reduction of the brake lever, it is easier to operate with the brake lever.

Compared with the prior art, the utility model has the following advantages and beneficial effects:

1. The operating head of the utility model includes the working head for opening and closing the working head. When the opening and closing operation is carried out by using the opening lever, the hook of the working head for opening and closing the working head can work well. Hook the parts to be operated, so as to avoid slippage of the operating head.

2. The adjacent insulating rod units of the utility model are connected by threads, and the operation is simple. According to actual needs, the insulating rod units can be used to assemble new insulating rods more conveniently, which is more user-friendly in use.

3. The utility model is equipped with an umbrella on the outer periphery of the sleeve, which can well prevent rainwater from slipping to the lower end of the brake rod, effectively protect the insulation performance of the brake rod, and avoid safety hazards caused by the decline in the insulation performance of the brake rod. Accidents happen.

4. The utility model can greatly reduce the weight of the brake rod without changing the working performance of the brake rod by adopting the hollow insulating rod. Due to the considerable weight reduction of the brake lever, it is easier to operate with the brake lever.
