FIG. 2 is an enlarged view of a portion of FIG. 1;

in the figure: 1-a sleeve; 2-a cyclic chain; 3, a safety buckle; 4, anchor cable; 5, a lockset; 6, a tray; 7-a buffer spring; 8, ladder beams; 9-pressing the alarm; 10-a support spring; 11-upper support plate; 12-a base plate; 13-a push rod; 14-an extension rod; 15-a handle; 16-lower support plate.

Detailed Description

In order to make the technical problems, technical solutions and advantageous effects to be solved by the present invention more clearly apparent, the present invention is further described in detail with reference to the embodiments and the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the utility model and are not intended to limit the utility model. The technical solution of the present invention is described in detail below with reference to the embodiments and the drawings, but the scope of protection is not limited thereto.

As shown in fig. 1-2, this embodiment provides a mining safety hook, including the sleeve pipe sub-assembly, link chain 2 and safety buckle 3, the sleeve pipe sub-assembly includes sleeve pipe 1, safety buckle 3 is connected with sleeve pipe 1 through link chain 2, the bottom of sleeve pipe 1 is equipped with bottom plate 12, be equipped with supporting spring 10 on the bottom plate 12, be equipped with backup pad 11 and bottom suspension fagging 16 in the sleeve pipe 1, upward be equipped with buffer spring 7 between backup pad 11 and the bottom suspension fagging 16, be equipped with the regulation pole on the bottom suspension fagging 16, the regulation pole runs through and establishes in the hole on bottom plate 12, be equipped with handle 15 on the regulation pole.

Further, the adjusting rod comprises a push rod 13 and an extension rod 14, a handle 15 is arranged at the bottom end of the extension rod 14, and the extension rod 14 is connected with the push rod 13 through threads.

Furthermore, a pressing alarm 9 is arranged on the bottom plate 12, and the pressing alarm 9 is arranged between the bottom plate 12 and the lower support plate 16 and is lower than the support spring 10.

Further, the handle 15 is a segment.

In practical use, the device consists of a 25mm sleeve 1, a 6mm multiplied by 28mm rigid loop chain 2 and an 8mm multiplied by 60mm rigid safety buckle 3, and can bear 500 kg tensile impact.
