Description

A retractable fastener for power engineering construction Technical Field

[0001] This utility model relates to the field of power fittings technology, and in particular to an expandable and retractable fastening fitting for power engineering construction. Background Technology

[0002] Electricity is the primary power source for industrial and agricultural production, national defense, and civil construction, and it is widely used in modern society. Transmitting electricity to users requires erecting power lines, which in turn requires utility poles, which in turn require fasteners and fittings. Therefore, a large number of fittings are needed in power engineering construction.

[0003] However, in long-term use, mismatched fastening hardware can cause delays in construction and prevent timely completion of projects. This is especially common in power grid construction and renovation and user substation construction. Therefore, those skilled in the art have provided a retractable fastening hardware for power engineering construction to solve the problems mentioned in the background art. Summary of the Invention

[0006] To achieve the above objectives, one embodiment of the present invention provides an expandable fastening fitting for power engineering construction, including a fastening plate and side ears. The fastening plate has a U-shaped structure, and side ears are fixedly connected to both ends of the fastening plate.

[0007] The fastening plate has a hollow center, and insulators are fixedly connected to the top and bottom surfaces of the fastening plate.

[0008] The side ear is provided with a positioning hole, a fastener is inserted into the positioning hole, and a fastening head is threaded to the end of the fastener;

[0009] A washer is fitted onto the portion of the fastener located between the side ears, with the outer washer abutting against the inner side of the side ear.

[0010] A locking element is movably connected to the middle of the fastening plate. The end face of the locking element is arc-shaped. A track is fixedly connected to the top of the locking element. The track is movably connected to the fastening plate.

[0011] The top surface of the lock has several lock holes, and a connector is fixedly connected to the outside of the fastening plate. A screw is inserted into the connector and threadedly connected to the lock hole to lock the position of the lock.

[0012] Preferably, in any of the above embodiments, the fastening plate is welded to the side lugs, and the number of washers clamped between the side lugs is adjustable.

[0013] The above technical solution is adopted: This device is specifically designed for the field of power engineering and is a special type of hardware.

[0018] The above technical solution involves two parts: the side lugs are locked at predetermined locations on the tower, and the spacing between the side lugs is adjustable. The side lugs are internally supported by varying numbers of washers, while the external lugs are secured with fastening heads. Therefore, the outer part of the fitting can freely expand or shrink according to the actual installation environment and conditions. More washers are used when expanding, and fewer washers are used when shrinking, making installation more flexible. Simultaneously, the internal part of the fitting, specifically the locking mechanism for clamping the cable, is adjustable front and back. The curved end face of the locking mechanism is used to close and position the cable, and the spacing between the end faces is adjustable. After adjustment, screws are used to connect and tighten the corresponding locking holes. This internally and externally expandable fitting offers stronger adaptability and better flexibility, reducing installation difficulties caused by size mismatches.

[0019] The robust locking mechanism and flexible adjustment design work together to ensure the safe clamping of the cable, reducing the risks caused by improper installation or loose cable.

[0020] There is no need to customize hardware of different sizes for different installation environments, thus saving production and procurement costs. Whether in the preparation stage before installation or in the adjustment stage during installation, this hardware demonstrates a high degree of flexibility, enabling operators to make quick and accurate adjustments according to the actual situation.

[0021] Preferably, of any of the above solutions, the washer is made of rubber and the outer end face of the lock is flat.
