Technical Field

[0001] The utility model relates to the technical field of lifting equipment, and in particular to a double-ring buckle which is convenient to disassemble. Background Art

[0002] The lifting equipment starts a vertical or vertical and horizontal working stroke after picking up the materials, unloads after reaching the destination, and then travels empty to the material picking location to complete a working cycle, and then performs a second lifting or transportation. Crane machinery can also be called lifting equipment. It is an important tool and equipment for industrial, transportation, and construction enterprises to realize the mechanization and automation of the production process, reduce heavy physical labor, and improve labor productivity. my country has a large number of various types of lifting equipment. Although the number of lifting equipment used in university laboratories is small and the lifting tonnage is not large, due to the low frequency of use of lifting equipment, its maintenance and safe operation are more important.

[0009] Furthermore, a limiting ring is fixedly connected to the bottom surface of the threaded rod, and the diameter of the limiting ring is greater than the diameter of the screw ring, which can effectively limit the screw ring and effectively prevent the screw ring from moving out from the outer surface of the threaded rod during movement, thereby avoiding affecting the normal use of the screw ring and the threaded rod.

[0010] Furthermore, the bottom surface of the limiting ring is fixedly connected to a vertical pole, and the bottom end of the vertical pole is fixedly connected to a baffle, which can limit the two pull rods and effectively prevent the pull rods from moving too much and causing gaps at the joints of the pull rods.

[0011] Furthermore, a swivel is fixedly connected to the top of the threaded rod, and a lifting ring is fixedly connected to the upper surface of the fixed ring. The staff can rotate the swivel, so that the swivel drives the threaded rod to rotate, which is convenient for use.

[0012] The working principle and beneficial effects of the utility model are:

[0013] 1. In the utility model, the staff rotates the threaded rod, and the threaded rod drives the screw ring to move on the outer surface of the threaded rod. The screw ring drives the two movable plates to move upward, and the movable plates drive the two pull rods to close through the connecting rod, thereby realizing the installation of the double ring buckle body. The whole can enable the staff to install the double ring buckle without the aid of tools, which is convenient and quick. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] Example 1

[0022] like Figure 1 to Figure 4 As shown, this embodiment proposes a double-ring buckle that is easy to disassemble, including a fixed ring 1, a disassembly mechanism 2 is arranged inside the fixed ring 1, the disassembly mechanism 2 includes two pull rods 206 hinged to the bottom of the fixed ring 1, the upper surface of each pull rod 206 is fixedly connected with a first connecting block 207, the upper surface of the fixed ring 1 is fixedly inlaid with a bearing 201, the inner ring of the bearing 201 is fixedly connected with a threaded rod 204, the outer surface of the threaded rod 204 is threadedly connected with a screw ring 209, the outer surface of the screw ring 209 is fixedly connected with two movable plates 203, the bottom surface of each movable plate 203 is fixedly connected with a second connecting block 202, the bottom surface of each second connecting block 202 is hinged with a connecting rod 205 through a pin shaft, the bottom end of the connecting rod 205 is hinged with the first connecting block 207 through a pin shaft, and the outer surface of each pull rod 206 is sleeved with a double-ring buckle body 208.

[0023] like Figure 1 As shown, cylindrical positions are opened on the outer surfaces of the two pull rods 206, and the cylinder is adapted to the inner circle of the double-ring buckle body 208, so that the double-ring buckle body 208 can be just stuck on the outer surface of the cylinder, which serves the purpose of limiting the double-ring buckle body 208 and effectively preventing the double-ring buckle body 208 from sliding left and right during use.

[0024] Reference Figure 1 The two pull rods 206 are arranged in an arc shape at the joint position, and the arc has no corners, which effectively prevents the staff from colliding with the corners of the pull rods 206 during the disassembly and installation of the double ring buckle body 208, thereby avoiding injuries to the staff.

[0025] Reference Figure 1 to Figure 3Two sleeves 5 are fixedly connected to the upper surface of the fixed ring 1, and a slide rod 3 is slidably connected to the interior of each sleeve 5. The bottom end of the slide rod 3 passes through the fixed ring 1 and is fixedly connected to the upper surface of the movable plate 203. The movable plate 203 can drive the slide rod 3 to move inside the sleeve 5 during the movement, thereby effectively ensuring the stability of the movable plate 203 during the movement, and effectively preventing the movable plate 203 from being deflected and stuck, thereby avoiding affecting the normal use of the disassembly mechanism 2.

[0026] Reference Figure 1 to Figure 3 The top of each slide rod 3 is fixedly connected with a slip ring 11, and the slip ring 11 is slidably connected to the inner wall of the sleeve 5. The slide rod 3 can drive the slip ring 11 to slide inside the sleeve 5, effectively increasing the stability of the slide rod 3 during movement and preventing the slide rod 3 from shaking during movement.
