[0022] The present invention will be further described in detail below with reference to the accompanying drawings and through examples. The following examples are provided to explain the present invention, but the present invention is not limited to the following examples.

[0023] The embodiment of the utility model comprises a bearing plate 1, a baffle 2, a locking assembly 3, a connecting frame 4, a lifting block 5, a supporting plate 7, a clamping groove 8, a reinforcing rib 9 and a lifting ring 10.

[0024] The support plate 7 is fixedly mounted on the top of the load-bearing plate 1, and the support plate 7 is used to support the hoisted objects. The enclosure 2 is connected from top to bottom, is hollow and square, and is placed on the load-bearing plate 1 to cover the support plate 7. The bottom of the enclosure 2 can fit the edge of the bottom of the load-bearing plate 1, and the enclosure 2 encloses the objects that need to be hoisted on the load-bearing plate 1 for protection. A buffer groove 6 is opened on the top of the load-bearing plate 1, and the interior of the buffer groove 6 is filled with polyurethane foam. The polyurethane foam has good elasticity and recovery, is lightweight and has high compression resistance, and its quality has relatively little impact on hoisting.

[0025] The locking assembly 3 includes a hinge support 304, a connecting rod 301, a lock 302 and an adjusting rod 303. There are four locking assemblies 3, which are respectively located on the front, back, left, and right sides of the outer surface of the enclosure 2. The outer surface of the enclosure 2 is fixedly installed with reinforcing ribs 9. The number of reinforcing ribs 9 is the same as the number of locking mechanisms, both of which are four. The four reinforcing ribs 9 are respectively located on the front, back, left, and right sides of the outer surface of the enclosure 2, and one reinforcing rib 9 matches one locking assembly 3. The hinge support 304 is fixedly installed on the outer surface of the reinforcing rib 9, so that the hinge support 304 is fixedly installed on the outer surface of the enclosure 2; the middle part of the connecting rod 301 is hinged to the hinge support 304, the lower end of the connecting rod 301 is fixed to the lock 302, and the upper end of the connecting rod 301 is fixed to the adjusting rod 303. A snap-fit ​​groove 8 is provided at the bottom of the bearing plate 1 , and the snap-fit ​​groove 8 is connected with the lock buckle 302 . When the lower end of the connecting rod 301 rotates inward, the lock buckle 302 can extend into the snap-fit ​​groove 8 to achieve locking between the enclosure 2 and the bearing plate 1 .

[0026] The connecting frame 4 is arranged at the top of the enclosure 2, and the connecting frame 4 is fixed to the top of the enclosure 2 through the connecting plates 11 fixedly connected at the four corners; the upper end of the connecting frame 4 is open, and the lower end is closed. The lifting block 5 is installed in the connecting frame 4 for up and down movement. The lifting block 5 is conical, specifically a quadrangular pyramid, and the upper parts of the four sides of the lifting block 5 are all inclined surfaces, and the cross-section becomes smaller as it goes up. The adjusting rod 303 is inclined toward the direction of the connecting frame 4, and the upper end of the adjusting rod 303 extends into the interior of the connecting frame 4 through the sliding hole 12 opened in the connecting frame 4 and is connected to the inclined surface of the lifting block 5. The upper ends of the adjusting rods 303 of the four locking assemblies 3 are respectively connected to the four inclined surfaces of the lifting block 5.

[0027] The place where the connecting rod 301 and the hinge support 304 are hinged divides the connecting rod 301 connecting the lock buckle 302 and the adjusting rod 303 into two upper and lower sections, and the upper end is longer; because the lifting block 5 is conical, when the lifting block 5 moves upward inside the connecting frame 4, the upper end of the adjusting rod 303 will be squeezed outward due to the rise of its inclined surface, and the lock buckle 302 will move toward the inside of the clamping groove 8, connecting and locking the enclosure 2 and the bearing plate 1 together.

[0028] When the external force exerted upward on the lifting block 5 is removed, the lifting block 5 slides toward the lower side of the inner part of the connecting frame 4 due to gravity, and the adjusting rod 303 extends into the upper end of the connecting frame 4 and loses the squeezing force, pushing the upper end of the connecting rod 301 toward the direction of the enclosure 2. The lock buckle 302 fixedly connected to the lower end of the connecting rod 301 can move outward from the snap-in groove 8, and the connection between the enclosure 2 and the supporting plate 1 is lost, so the lock can be unlocked, and the connecting frame 4 can be lifted as a whole to separate the enclosure and the supporting plate 1.

[0029] A lifting ring 10 is fixed on the top of the lifting block 5 to facilitate the crane to lift the protective frame. After the lifting ring 10 lifts the lifting block 5, the lifting block 5 will have a tendency to move upward relative to the connecting frame 4. When the lifting block 5 squeezes the adjusting rod 303 outward until the lower end of the connecting rod 301 is blocked by the enclosure 2, the lower end of the connecting rod 301 cannot continue to move inward, which also indirectly limits the lifting block 5.

[0030] In addition, it should be noted that the shapes and names of the parts and components of the specific embodiments described in this specification may be different, and the above content described in this specification is only an example of the structure of the utility model. All equivalent changes or simple changes made based on the structure, features and principles described in the patent concept of the utility model are included in the protection scope of the utility model patent. Technicians in the technical field of the utility model can make various modifications or supplements to the specific embodiments described or replace them in a similar manner, as long as they do not deviate from the structure of the utility model or exceed the scope defined by the claims, they should all fall within the protection scope of the utility model.
