[0028] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0029] Next, the present invention is described in detail with reference to schematic diagrams. For ease of illustration, cross-sectional views of device structures may be partially enlarged and not to scale when describing the embodiments of the present invention. Furthermore, the schematic diagrams are merely illustrative and should not limit the scope of protection of the present invention. Furthermore, in actual production, three-dimensional dimensions, including length, width, and depth, should be included.

[0030] In order to make the purpose, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0031] See also Figures 1 to 4 As shown, this embodiment is a self-locking scaffolding fixing device with high safety, comprising:

[0032] A lifting plate 13, with support frames 12 fixed on both sides of the upper surface of the scaffold 11, and the lifting plate 13 is slidably installed inside the scaffold 11;

[0033] The lifting plate 13 is a platform in the electric scaffolding for directly carrying goods. The support frame 12 is fixed on both sides of the upper surface of the scaffolding 11 to provide stable support and guidance for the movement of the lifting plate 13.

[0034] Self-locking assembly, the self-locking assembly includes a fixing hole 23, a safety door 22, a fixing block 24, a mounting hole 25, a spring 26 and a fixing column 27. The safety door 22 is hinged on both sides of the upper side of the lifting plate 13. The fixing holes 23 are provided on both sides of the top surface of the lifting plate 13. The fixing block 24 is fixed to the lower end of one side of the safety door 22. The mounting hole 25 is provided in the center of the bottom surface of the fixing block 24. The spring 26 is fixed inside the mounting hole 25. The fixing column 27 is fixedly connected to the lower end of the spring 26;

[0035] The fixing hole 23 is used to cooperate with the fixing column 27 to realize the locking function. When the fixing column 27 is inserted into the fixing hole 23, the safety door 22 can be locked in a closed state to prevent the safety door 22 from opening accidentally. The mounting hole 25 is used to install the spring 26. The function of the spring 26 is to provide elastic force for the fixing column so that it can automatically position and lock in the fixing hole 23.

[0036] Fixed plates 21 are fixed on both sides of the lifting plate 13, and two sets of safety doors 22 are hinged on both sides of the fixed plate 21. The fixing holes 23 correspond to the mounting holes 25 in a positive direction, and the lower ends of the fixing columns 27 extend into the fixing holes 23. The lower ends of the fixing columns 27 are provided with an oblique groove, and the lower end diameter of the fixing columns 27 is smaller than the upper end diameter. An unlocking groove 241 is provided on one side of the outer surface of the fixing block 24, and a connecting plate 28 is fixed on one side of the outer surface of the fixing column 27. The connecting plate 28 slides through the unlocking groove 241.

[0037] When the safety door 22 needs to be opened, the unlocking slot 241 can be operated to overcome the elastic force of the spring 26 and push the connecting plate 28 upward to compress the spring 26 and move the fixing column 27 upward so that the fixing column 27 exits the fixing hole 23, thereby releasing the locked state.

[0038] Working principle:

[0039] When the cargo enters the lifting plate 13, when the operator closes the safety door 22, the closing of the safety door 22 synchronously drives the fixed block 24 to move, and the fixed block 24 drives the fixed column 27 to move. When the safety door 22 is closed, the fixed column 27 will first contact the lifting plate 13. Under the guidance of the inclined groove at the lower end of the fixed column 27, the spring 26 is pressed inward to move the fixed column 27 upward. When the fixed column 27 is positively aligned with the fixing hole 23, the elastic force of the spring 26 presses the fixed column 27 downward so that the fixed column 27 is stuck in the fixing hole 23, locking the safety door 22. The automatic locking mechanism of the safety door 22 and the fixed column 27 can effectively prevent the safety door 22 from being accidentally opened during the cargo lifting process.

[0040] This step does not require manual intervention. As long as the safety door 22 is closed, the locking process can be automatically completed, which greatly reduces the safety risks caused by human errors.

[0041] See also Figures 1 to 4 As shown; this embodiment is based on the above embodiment 1 and also includes:

[0042] The clamping assembly includes an electric push rod 31 and a clamping column 32. The four electric push rods 31 are fixed below the two sets of safety doors 22. The output end of the electric push rod 31 is fixedly connected to the clamping column 32. The outer surface of the support frame 12 is provided with a clamping groove 33, and the end of the clamping column 32 extends into the interior of the clamping groove 33.

[0043] The electric push rod 31 is the power source of the entire clamping assembly, and the clamping column 32 is the key component for locking the lifting plate 13. When the electric push rod 31 is extended, the clamping column 32 moves to both sides under the drive of the push rod, and finally inserts into the clamping slot 33 of the support frame 12, firmly connecting the lifting plate 13 and the support frame 12 together.

[0044] Working principle:

[0045] After the lifting plate 13 rises to the desired position, the staff activates the extension and retraction of the electric push rod 31 through the external controller. The electric push rod 31 extends, driving the clamping column 32 to move to both sides, and the clamping column 32 sinks into the clamping slot 33, locking the lifting plate 13.

[0046] In this step, during the process of the lifting plate 13 rising or falling, or during use, even if it is affected by external forces, the locking state can be kept stable and will not become loose or fall off.
