Description

Technical Field

[0001] The utility model relates to the technical field of quick-insert buckle components, in particular to a steel quick-insert buckle. Background Art

[0002] A safety belt is a piece of personal protective equipment that prevents workers working at heights from falling or that suspends workers safely after a fall. It can be divided into the following three categories according to different conditions of use: 1. Pole work safety belt, which binds the human body to a fixed structure through a rope or belt wrapped around a fixed structure, allowing the worker's hands to perform other operations; 2. Area restriction safety belt, which limits the worker's range of movement and prevents him from reaching areas where a fall may occur; 3. Fall suspension safety belt, which suspends workers when workers working at heights or climbing fall. Quick-release buckles play a key role in this.

[0003] However, the existing quick-insertion buckles all realize the quick-insertion function through triggering, so when used on site, there may be a risk of accidental touch, resulting in a tripping phenomenon. Utility Model Content

[0004] Technical issues solved

[0005] In view of the above-mentioned shortcomings of the prior art, the utility model provides a steel quick-release buckle, which can effectively solve the problem that the existing quick-release buckles in the prior art all realize the quick-release function through triggering, so there is a risk of accidental touch when used on site, causing the problem of tripping.

[0006] Technical Solution

[0007] In order to achieve the above objectives, the present invention is implemented through the following technical solutions:

[0008] The utility model provides a steel quick-release buckle, comprising a base plate; a covering piece is fixed on the top of the base plate, a limiting groove is provided on the top of the covering piece, a positioning groove structure is provided on the inner bottom end of the limiting groove, a clamping groove is provided in the middle of the base plate, a buckle ring is integrally fixed to the bottom end of the base plate, a buckle plate is provided inside the buckle ring, the bottom ends of the clamping groove and the limiting groove overlap, a pressing piece is fixed inside the limiting groove, the pressing piece comprises a pressing block and a limiting rod fixed to the front end of the pressing block, the pressing block is arranged in the limiting groove, and the limiting rod is clamped in the positioning groove.

[0009] Furthermore, a connecting hole is provided in the middle of the cover, and a positioning hole is provided at one end of the base plate, and the connecting hole and the positioning hole are fixedly connected by a locking bolt and a nut.

[0010] Furthermore, the buckle is a 180-degree bending structure, and the bending portion is a rounded structure.

[0011] Furthermore, two groups of the limiting grooves are symmetrically provided on the cover, and the top of each group of the pressing blocks is recessed downwards and an anti-slip strip is provided on the top thereof.

[0012] Furthermore, the buckle plate is a hollow annular structure.

[0013] Furthermore, the inner diameter of the buckle plate is matched with the outer dimension of the buckle ring.

[0014] Beneficial Effects

[0015] Compared with the known public technology, the technical solution provided by the utility model has the following beneficial effects:

[0016] 1. The utility model sets a pressing piece structure, and two groups of pressing blocks are fixed in the positioning groove through the limit rod, and the pressing block is clamped in the limit groove, and is clamped on the buckle ring through the buckle plate to play a blocking role. When in use, the buckle plate needs to be rotated 90 degrees on the buckle ring to a vertical state. The two buttons (pressing blocks) are pressed and opened at the same time (two actions) to rotate the buckle plate 90 degrees to disengage the cover and the bottom plate. If it is not opened vertically and slightly forced, the quick plug will be locked immediately, which can prevent the quick plug from being disengaged due to accidental opening of the button.

[0017] 2. In this device, plastic parts and steel parts are combined to ensure strength while reducing weight. The opening method only requires two conventional quick-insert actions. A new step is added to rotate the buckle plate to keep it in a vertical state, which is safer. At the same time, only one closing action is required, which is convenient for wearing.
