Description

Technical Field

[0001] The utility model relates to the technical field of lifting slings, in particular to a lifting module. Background Art

[0002] The lifting module is also called a lifting lug or a lifting hook for automobile molds. It is used in the process of lifting heavy objects. According to the existing Chinese utility model patent with the announcement number CN209922697U, a lifting module is recorded, in which a retaining ring and a bolt cap are sequentially sleeved on one end of the supporting screw from the inside to the outside, a spring spring is sleeved on the supporting screw, and the spring spring is arranged between the supporting screw and the retaining ring. Then, when the spring spring is installed in the retaining ring, the central axis of the retaining ring is offset under the support of the spring spring, and the central axis of the retaining ring is not located on the central axis of the supporting screw. At this time, the retaining ring partially protrudes from the outer diameter of the supporting screw, thereby effectively preventing the fixing bolt from falling off the support and preventing the workpiece from slipping during the lifting process.

[0003] However, the support in this structure is a flat structure. When fixing and lifting some mechanical frames or mold corners, whether it is placed flat or sideways, it cannot provide a good supporting and fixing effect. The upward force of the steel cable will cause the assembly bolts in the support to deviate radially, such as Figure 1 As shown, therefore, in view of these current situations, it is urgent to develop a lifting module to meet the needs of practical use.

The present invention is described in detail below in conjunction with the drawings.

[0022] See also Figure 1-5 A lifting module specifically implemented therein includes a support member 1 and a fixing bolt 2. The bottom of the support member 1 is a fixing portion 11 for assembling a lifting object, and the top of the support member 1 is a mounting portion 12 for assembling a steel cable. The fixing bolt 2 is horizontally arranged inside the mounting portion 12. Specifically, a "U"-shaped groove is provided in the middle of the mounting portion 12, and both ends of the fixing bolt 2 are respectively horizontally arranged inside the "U"-shaped groove. A horizontal supporting protrusion 3 extending horizontally outward is provided between the fixing portion 11 and the mounting portion 12. The horizontal supporting protrusion 3 and the fixing portion 11 are distributed in a vertical structure. The fixing portion 11 and the horizontal supporting protrusion 3 are respectively provided with a plurality of first fixing holes 111 and second fixing holes 31.

[0023] Specifically, Figure 4 As shown, one end of the fixing bolt 2 is a horizontally raised limit nut 21, the other end of the fixing bolt 2 is a threaded end 23, the middle part of the fixing bolt 2 is a smooth rod part 22, the fixing bolt 2 passes through the two sides of the mounting part 12 in sequence through the threaded end 23, and the limit screw abuts against one of the side surfaces of the mounting part 12, the threaded end 23 extends to the other side surface of the mounting part 12, and a fixing nut 25 is provided at the end of the threaded end 23, the fixing nut 25 is threadedly connected to the threaded end 23, and a retaining ring 24 is provided between the fixing nut 25 and the side wall of the mounting part 12, and the retaining ring 24 is clamped between the fixing nut 25 and the side wall of the mounting part 12.

[0024] A horizontal supporting protrusion 3 extending horizontally outward is provided between the fixing portion 11 and the lifting portion 12, wherein the horizontal supporting protrusion 3 and the fixing portion 11 are distributed in a vertical structure. During use, the fixing portion 11 and the horizontal supporting protrusion 3 can be respectively fixed at the corners of the object to be lifted, wherein the top surface and side wall of the object to be lifted can be fixed to the fixing portion 11 through external fixing bolts, the horizontal supporting protrusion 3, and the horizontal supporting protrusion 3. At the same time, the horizontal supporting protrusion 3 can transfer the radially offset force of the support member 1 to one side of the horizontal supporting protrusion 3, thereby effectively reducing the deformation of the assembly bolts due to the radial offset.

[0025] In a further solution, a downwardly sunken area 112 is provided at one end of the fixing portion 11 away from the horizontal supporting protrusion 3, the horizontal height of the sunken area 112 is smaller than the mounting portion 12, and a vertically arranged reinforcing rib 4 is provided in the middle of the sunken area 112, the reinforcing rib 4 is arranged between the sunken area 112 and the bottom end surface of the mounting portion 12, the reinforcing rib 4 is specifically an oblique wedge structure, and one end of the reinforcing rib 4 is arranged to be inclined upward toward one side of the mounting portion 12;

At this time, since the reinforcing rib 4 is obliquely wedge-shaped and arranged between the sinking area 112 and the bottom end surface of the mounting portion 12, the rigidity between the fixing portion 11 and the mounting portion 12 can be enhanced, and the deflection force obliquely downward produced by the fixing portion 11 toward the side of the horizontal supporting protrusion 3 can be effectively reduced.
