Description

Technical Field

[0001] This utility model relates to the field of buckle device technology, and in particular to a corrosion-resistant double-beam hook anti-disengagement safety buckle device. Background Technology

[0002] In the copper smelting process, the copper wire is added to the copper melting pot using an overhead crane. During the lifting process, a clamp is needed to securely connect the steel wire rope to the copper wire binding point or the crane hook, ensuring that the connection will not loosen or fall off during the lifting process. This allows the crane to stably lift the copper wire and accurately drop it into the copper melting pot.

[0003] Traditional spring-loaded safety catches often fail to reset properly during hoisting operations, leading to safety catch failure and the risk of disengagement. In addition, ordinary steel bar safety catches are easily corroded by sulfuric acid mist in acidic environments, affecting their service life and safety performance. There is a lack of a safety catch device that is both corrosion-resistant and effectively prevents disengagement in the current technology, resulting in low work efficiency and safety hazards.

[0004] Therefore, those skilled in the art have provided a corrosion-resistant double-beam hook anti-disengagement safety buckle device to solve the problems mentioned in the background art. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Reference Figure 1-4 This utility model provides an embodiment of a corrosion-resistant double-beam hook anti-disengagement safety buckle device, comprising a buckle body 1, the buckle body 1 including a base layer 101, and a corrosion-resistant layer 102 fixedly disposed on the outer surface of the base layer 101. The anti-disengagement mechanism 2 is rotatably disposed at the front end of a connecting block 4, the anti-disengagement mechanism 2 including a bushing 201, a fixed shaft 202 fixedly disposed in the middle of the bushing 201, a rotating sleeve 203 rotatably disposed on the outer surface of the fixed shaft 202, a first limiting rod 204 fixedly disposed on both sides of the front end of the rotating sleeve 203, a second limiting rod 205 fixedly disposed on both sides of the rear end of the rotating sleeve 203, and a torsion spring sleeved on the outer surface of the fixed shaft 202, the torsion spring being connected to the rotating sleeve 203. Specifically, the buckle body 1 is made of 316L stainless steel, and its surface is polished to reduce surface roughness and lower the risk of corrosion. The corrosion-resistant layer 102 uses a polytetrafluoroethylene (PTFE) coating, which has excellent acid resistance and wear resistance, giving the buckle excellent corrosion resistance and further enhancing its corrosion resistance. The anti-disengagement mechanism 2 is equipped with an automatic reset device to ensure that the buckle quickly resets after hoisting to prevent it from falling off. The connecting block 4 facilitates the installation of the anti-disengagement mechanism 2. The bushing 201 facilitates the fixed installation of the fixed shaft 202, and the fixed shaft 202 facilitates the rotation of the rotating sleeve 203. The rotating sleeve 203 facilitates its use in conjunction with the first limit rod 204 and the second limit rod 205. When an item enters the buckle body 1, the first limit rod 204 is pressed down to open. When the item enters the buckle body 1, the first limit rod 204 is reset by the torsion spring and works with the second limit rod 205 to prevent it from opening, thus enhancing the stability during use, preventing the problem of disengagement, and facilitating use.

[0020] Reference Figure 2-3 The upper ends of both sides of the buckle body 1 are threaded with a double beam mechanism 3. The double beam mechanism 3 includes two double beam plates 301. A connecting rod 302 is provided through the upper middle and front sides of the two double beam plates 301. A welding plate 304 is fixedly provided on the upper end of the two double beam plates 301. A support block 305 is fixedly provided on the lower front and rear sides of the two welding plates 304. A reinforcing rib 306 is fixedly provided on the middle of the outer side of the two double beam plates 301. A threaded sleeve body 303 is threadedly provided on the outer surface of the two connecting rods 302. Specifically, the double beam mechanism 3 can effectively distribute the lifting load, the two double beam plates 301 help to distribute the lifting pressure, the connecting rod 302 is used in conjunction with the threaded sleeve body 303, which is conducive to the connection and installation of the two double beam plates 301 and enhances the stability during use, the welding plate 304 helps to increase the welding area, and when used in conjunction with the support block 305, it helps to improve the connection stability, and the reinforcing rib 306 helps to enhance the strength of the double beam plate 301 and improve the service life of the double beam plate 301.

[0021] Working principle: The outer surface of the base layer 101 of the buckle body 1 is coated with a corrosion-resistant layer 102, giving it excellent corrosion resistance. When an item enters the buckle body 1, the item presses down on the first limiting rod 204 of the anti-disengagement mechanism 2. Since the first limiting rod 204 is fixed to the front end of the rotating sleeve 203, the rotating sleeve 203 will rotate around the fixed shaft 202 fixed in the middle of the bushing 201. At this time, the torsion spring connected to the rotating sleeve 203 on the outer surface of the fixed shaft 202 is deformed by force. When the item enters the buckle body 1, the torsion spring returns to its original shape, driving the rotating sleeve 203 to reset. The first limiting rod 204 also resets and cooperates with the second limiting rod 205 at the rear end of the rotating sleeve 203 to prevent the anti-disengagement mechanism 2 from opening and avoid disengagement. At the same time, the automatic reset device of the anti-disengagement mechanism 2 ensures that the buckle is quickly reset after hoisting is completed. Secondly, the double beam mechanism 3 includes two double beam plates 301, which can effectively distribute the lifting load. The two double beam plates 301 play the role of distributing the lifting pressure. The connecting rods 302, which are installed through the upper front and rear sides of the middle of the two double beam plates 301, cooperate with the threaded sleeve body 303 to realize the connection and installation of the two double beam plates 301, thereby enhancing the stability during use. The welding plate 304 at the upper end of the two double beam plates 301 increases the welding area and cooperates with the support blocks 305 at the lower front and rear sides of the welding plate 304 to improve the stability of the connection. The reinforcing ribs 306 at the middle of the outer side of the two double beam plates 301 enhance the strength of the double beam plates 301, improve their service life, and enable the entire device to stably bear the load during lifting.
