Description

A convenient self-locking hook

technical field

The utility model relates to a convenient self-locking hook.

Background technique

At present, in the work of replacing the insulator string of the 500kV ultra-high voltage overhead transmission line, it is necessary to connect the suspender with a screw to replace the insulator and connect the wire to play the role of fixing the wire. Usually, the lead screw and the boom are connected by a U-shaped ring, and the U-shaped ring needs to be fixed with bolts. When the staff is working at heights, due to the limited space and single-person work, they need to carry the boom (about 30-35 catties) in one hand. ), disassembly and assembly with one hand, and in the case of wearing gloves, it is extremely inconvenient to disassemble and assemble the bolts of the U-shaped ring, and the movement range is large, the operation time is long, the efficiency is low, the physical strength of the operator is high, and there are potential safety hazards. In this case, usually two people are required to work together to complete the relevant operations. In order to solve the above problems, we need to replace the U-shaped ring with an easy-to-operate device to connect the boom and the lead screw.

Utility model content

The technical problem to be solved by the utility model is to provide an easy-to-use self-locking hook capable of connecting the suspender and the lead screw with a simple structure and high safety.

The utility model adopts the following technical solutions:

The utility model comprises a hook main body, a fixed shaft arranged on both sides of the tail of the hook main body, and a lock flap hinged with the hook main body through the fixed shaft. In the groove; the lock flap is provided with two connecting arms, and the two connecting arms are respectively hinged with the connecting ring; two torsion springs are arranged between the hook main body and the lock flap, and the two The two torsion springs are respectively sleeved on the two fixed shafts; the bottom of the hook main body is provided with a connecting seat, and the bottom of the connecting seat is provided with a threaded connection hole.

The connecting ring described in the utility model can be provided with a pull cord.

The positive effect of the utility model is as follows:

When using the utility model, the main body of the hook and the lead screw are connected together through the threaded connection hole arranged at the bottom of the connecting seat, because the lock flap and the main body of the hook are hinged through the fixed shaft, and the two ends of the torsion spring nested on the fixed shaft Lean on the lock flap and the main body of the hook respectively, so that under the action of external force, the lock flap turns to the inner side of the hook main body, the opening of the hook opens, and is buckled with the hanging ring on the suspender, and then locked under the action of the torsion spring. The flap automatically bounces back to the original position, locking the opening of the hook, which is safe and reliable, easy to operate, reduces the workload of personnel at heights, and improves work efficiency.

Since the top of the lock flap is placed in the groove inside the front end of the hook main body, the lock flap is not easy to collapse outwards, nor is it easy to be accidentally pried open by objects connected to the hook, which greatly increases the safety factor of the hook; There are two connecting arms on the flap, and the connecting rings are respectively hinged with the two connecting arms. After use, pull down the connecting ring or pull the pull rope, the lock flap will rotate inward, and the opening of the hook will open, without pressing the lock by hand. flap, the hook can be removed.

The utility model is used to connect the suspender rod and the lead screw, no matter whether it is buckled or disassembled, the operation is very simple, and the safety is high, which reduces the burden of high-altitude workers.

Detailed ways

Shown in accompanying drawing 1～3 is a specific embodiment of the utility model, and the utility model comprises hook main body 1, the fixed shaft 4 that is arranged on both sides of hook main body 1 tail and the lock that is hinged with hook main body 1 through fixed shaft 4 Flap 3, the inner side of the front end of the hook main body 1 is provided with a groove 2, the top of the lock flap 3 is placed in the groove 2; the lock flap 3 is provided with two connecting arms 10, the two connecting arms The arms 10 are respectively hinged with the connecting ring 9; two torsion springs 7 are arranged between the hook main body 1 and the lock flap 3, and the two torsion springs 7 are respectively sleeved on the two fixed shafts 4; The bottom of the hook main body 1 is provided with a connecting seat 5, and the bottom of the connecting seat 5 is provided with a threaded connection hole 8; the connecting ring 9 may be provided with a pull cord.

As shown in accompanying drawing 1, when using the utility model, the hook main body 1 and the lead screw 6 are connected together through the threaded connection hole 8 arranged at the bottom of the connecting seat 5, because the lock flap 3 and the hook main body 1 are hinged through the fixed shaft 4 connected, and the two ends of the torsion spring 7 nested on the fixed shaft 4 respectively lean on the lock flap 3 and the hook main body 1, so that under the action of external force, the lock flap 3 rotates to the inside of the hook main body 1, and the hook opening opens. It is buckled together with the hanging ring on the boom, and then the locking flap 3 automatically bounces back to the original position under the action of the torsion spring 7, locking the opening of the hook, which is safe, reliable, easy to operate, and reduces the workload of personnel at high altitude. Improve work efficiency.

Since the top of the lock flap 3 is placed in the groove 2 inside the front end of the hook main body 1, the lock flap 3 is neither easy to collapse outwards nor be accidentally pried open by objects connected to the hook, which greatly increases the safety of the hook Coefficient; because two connecting arms 10 are arranged on the lock flap 3, the connecting ring 9 is hinged with the two connecting arms 10 respectively, after use, pull the connecting ring 9 downward or pull the stay rope, and the locking flap 3 rotates inwardly, The opening of the hook is opened, and the hook can be taken off without pressing the lock flap 3 by hand.

The utility model is used to connect the suspender rod and the lead screw, no matter whether it is buckled or disassembled, the operation is very simple, and the safety is high, the burden of the high-altitude workers is reduced, the labor intensity is reduced, and the work efficiency can be effectively improved.
