Description

Technical Field

[0001] The utility model relates to the technical field of head protection devices, and particularly relates to a high-strength head protection mechanism. Background Technique

[0002] The head protection mechanism is a device specifically designed to protect the head from external impacts, corrosion or other damages, and plays a role in extending the service life of the head. As an important component in a pressure vessel or pipeline system, the safety and stability of the head are crucial for the operation of the entire system.

[0003] For this reason, the patent with the publication number CN218113596U discloses a high-strength head protection mechanism, which includes a head main body. A protection mechanism is arranged at the top of the head main body, and a positioning mechanism is arranged at the bottom of the outer circle of the head main body. The protection mechanism includes a threaded rod, the threaded rod is fixedly connected to the top of the head main body, and a first threaded cylinder is threadedly connected to the outer circle of the threaded rod. In this high-strength head protection mechanism, through the arranged protection mechanism, the staff only needs to rotate the knob to complete the installation and disassembly of the protection shell. When the protection shell is impacted, the reinforcing fins arranged inside the protection shell support the overall structure of the protection shell, buffer the impact force, increase the overall strength of the protection shell structure, and at the same time, the protection shell isolates the head main body from the external environment, reduces the interaction between the outer surface of the head main body and the external environment, and improves the service life of the head main body;

[0004] The above-mentioned protection shell needs to be locked and fixed through several groups of threaded rods. Due to the threaded connection, it is time-consuming and laborious during assembly or disassembly. Moreover, the threaded rods are small in volume and are easy to be lost after disassembly, which brings inconvenience in assembly, affects the work efficiency of workers, and is not convenient for daily maintenance and repair. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a high-strength head protection mechanism to solve the defect that the existing high-strength head protection mechanism is inconvenient to disassemble and assemble.

[0006] To solve the above technical problems, the utility model provides the following technical solution: A high-strength head protection mechanism, including a protection shell and a head main body; the protection shell is movably installed outside the head main body, and a limiting mechanism is arranged at the connection between the protection shell and the head main body, and a first protection pad is fixedly installed between the protection shell and the head main body; the limiting mechanism includes a clamping groove, a clamping buckle, a connecting column, a clamping block and a second spring; the clamping blocks are movably arranged at the corners of the bottom of the protection shell, the outer parts of the clamping blocks are all wound with second springs, one end of each clamping block is hinged with a clamping buckle, clamping grooves are fixedly installed on the outer walls of the head main body at the ends of the clamping blocks far away from the clamping buckles, and the connecting column is arranged at the top of the head main body.

[0007] Preferably, a snap-fit structure is formed between the card slot and the card block, and a sliding structure is formed between the card block and the protective shell.

[0008] Preferably, the connecting column includes a connecting shaft, a limiting block, a sliding block, a convex block and a first spring, and the convex block is fixedly installed at the top end of the connecting column.

[0009] Preferably, a sliding block is movably installed outside the connecting column at the bottom end of the convex block, and a sliding structure is formed between the sliding block and the connecting column. Connecting shafts are movably arranged inside the protective shell on both sides of the sliding block.

[0010] Preferably, a sliding structure is formed between the connecting shaft and the protective shell. First springs are wound around the outside of the connecting shafts, and limiting blocks are fixedly installed on the opposite sides of the connecting shafts.

[0011] Preferably, the opposite sides of the limiting blocks are inclined downward, the convex block is inclined upward, and the sliding block is inclined downward.

[0012] Preferably, a plurality of groups of first protective pads are provided, and second protective pads are fixedly arranged on the inner walls of the protective shell inside the first protective pads. Both the first protective pad and the second protective pad are arc-shaped, and the arc height of the second protective pad is higher than that of the first protective pad.

[0013] A high-strength head protection mechanism provided by the present utility model has the following advantages: By setting a limiting mechanism, directly pressing the protective shell downward causes the limiting blocks to slide to both sides and press downward to the bottom of the convex block. After snap-fitting and fixing, the card block at the bottom of the protective shell is aligned with the card slot at the bottom of the head body, and the buckle is flipped to one side. After the second spring loses its tensile force, it rebounds and pushes the card block into the card slot to achieve snap-fitting and fixing. When disassembling, flipping the buckle outward causes the card block to move away from the card slot, and then pressing the protective shell downward again causes the limiting blocks to slide to the bottom of the sliding blocks, and then directly lifting upward can disassemble the protective shell, thereby realizing that the high-strength head protection mechanism is convenient for disassembling and assembling the protective shell, simplifying the operation, improving work efficiency, and reducing maintenance costs.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] Please refer to Figures 1 - 6, a high-strength head protection mechanism provided by the utility model includes a protective shell 1 and a head main body 3; a protective shell 1 is movably installed outside the head main body 3, and a limiting mechanism 2 is arranged at the connection between the protective shell 1 and the head main body 3. A first protective pad 4 is fixedly installed between the protective shell 1 and the head main body 3; the limiting mechanism 2 includes a clamping groove 21, a clamping buckle 22, a connecting column 23, a clamping block 24 and a second spring 25; the clamping blocks 24 are movably arranged at the corners of the bottom of the protective shell 1, and the second springs 25 are wound around the outside of the clamping blocks 24. One end of each clamping block 24 is hinged with a clamping buckle 22. Clamping grooves 21 are fixedly installed on the outer walls of the head main body 3 at the ends of the clamping blocks 24 far away from the clamping buckles 22. The connecting column 23 is arranged at the top of the head main body 3. A clamping structure is formed between the clamping groove 21 and the clamping block 24, and a sliding structure is formed between the clamping block 24 and the protective shell 1. The connecting column 23 includes a connecting shaft 231, a limiting block 232, a sliding block 233, a convex block 234 and a first spring 235. The convex block 234 is fixedly installed at the top of the connecting column 23. A sliding block 233 is movably installed outside the connecting column 23 at the bottom end of the convex block 234, and a sliding structure is formed between the sliding block 233 and the connecting column 23. Connecting shafts 231 are movably arranged inside the protective shell 1 on both sides of the sliding block 233. A sliding structure is formed between the connecting shaft 231 and the protective shell 1. The first springs 235 are wound around the outside of the connecting shafts 231. Limiting blocks 232 are fixedly installed on the opposite sides of the connecting shafts 231. The opposite sides of the limiting blocks 232 are inclined downward, the convex block 234 is inclined upward, and the sliding block 233 is inclined downward. There are several groups of the first protective pads 4, and second protective pads 5 are fixedly arranged on the inner walls of the protective shell 1 inside the first protective pads 4. Both the first protective pads 4 and the second protective pads 5 are arc-shaped, and the arc height of the second protective pad 5 is higher than that of the first protective pad 4;

[0023] Refer to the attached Figure 2 , Figure 3 , Figure 5 and Figure 6, when the device is in use, pull the handle to directly place the protective shell 1 outside the head main body 3, press downwards, so that the limiting block 232 slides towards both sides and presses down to the bottom of the convex block 234.
