Detailed implementation mode

[0023] As Figures 1 - 5 shown, the present utility model provides a technical solution: a building guardrail with a splicing structure, including a support base 1 and a guardrail 4. A sliding groove 2 is formed on the side wall of the support base 1. A sliding block 3 is slidably installed on the inner wall of the sliding groove 2. A guide rod 7 is fixed inside the sliding block 3. The outer wall of the guide rod 7 is attached to a mounting block 6. A guardrail 4 is fixed on the side wall of the mounting block 6. There are two groups of the support base 1, the sliding block 3, the mounting block 6 and the guide rod 7, and the two groups of the support base 1, the sliding block 3, the mounting block 6 and the guide rod 7 are symmetrically arranged with the center line in the vertical direction of the guardrail 4 as the axis of symmetry. A handle 5 is fixed on the outer wall of the guardrail 4. By providing the handle 5, it is convenient to take the guardrail 4. The bottom of the sliding block 3 is provided with a disassembly and assembly mechanism 8.

[0024] Specifically, the disassembly and assembly mechanism 8 includes a fixed sleeve 81, a spring 83, a rotating rod 82, a rotating block 84, a connecting groove 85, a moving block 86, a movable rod 87, a limiting rod 88 and a limiting hole 89. The fixed sleeve 81 is fixed to the bottom of the guardrail 4. The inner wall of the fixed sleeve 81 is rotatably installed with the rotating rod 82. A spring 83 is fixed to the outer wall of the rotating rod 82. The side of the spring 83 away from the rotating rod 82 is fixed to the inner wall of the fixed sleeve 81. By setting the spring 83, the effect of resetting the rotating rod 82 can be achieved. The bottom of the rotating rod 82 is fixed with the rotating block 84. A connecting groove 85 is opened at the bottom of the guardrail 4. The inner wall of the connecting groove 85 is slidably installed with the moving block 86. There are two groups of moving blocks 86, and the two groups of moving blocks 86 are symmetrically arranged with the center line of the guardrail 4 in the vertical direction as the axis of symmetry. The bottom of the rotating block 84 is hinged with the movable rod 87. One end of the movable rod 87 away from the rotating block 84 is hinged with the bottom of the moving block 86. When the rotating block 84 is reversed, the rotating rod 82 can be reversed, and the spring 83 can be contracted. When the rotating block 84 is reversed, the rotating block 84 can pull the movable rod 87, so that the movable rod 87 rotates at the hinge, and the two groups of moving blocks 86 can be pulled to approach each other. A limiting rod 88 is fixed to the side of the moving block 86 away from the movable rod 87. A limiting hole 89 is opened on the side wall of the slider 3. The diameter of the limiting rod 88 matches the diameter of the limiting hole 89. Through the cooperation of the limiting rod 88 and the limiting hole 89, the guardrail 4 can be fixed on the slider 3, so that the guardrail 4 is connected to the support seat 1. When the two groups of moving blocks 86 approach each other, the limiting rod 88 can be removed from the limiting hole 89, and the limit on the guardrail 4 can be released. The guardrail 4 can be moved upward, so that the mounting block 6 can be removed from the guide rod 7, which is convenient for disassembling and assembling the guardrail 4 and the support seat 1.

[0025] Specifically, a limiting mechanism 9 is provided on the slider 3. The limiting mechanism 9 includes a slot hole 91, a return spring 93, a limiting post 92, and a limiting groove 94. The slot hole 91 is opened on the slider 3. The limiting post 92 is slidably installed on the inner wall of the slider 3. A return spring 93 is fixed on the side of the limiting post 92 close to the guardrail 4. The side of the return spring 93 away from the limiting post 92 is fixed on the inner wall of the slot hole 91. By providing the return spring 93, the effect of limiting the limiting post 92 can be achieved. The limiting groove 94 is opened on the inner wall of the slot hole 91. The inner wall of the limiting groove 94 fits with the outer wall of the limiting post 92. By the cooperation of the limiting groove 94 and the limiting post 92, the effect of limiting the slider 3 can be achieved. When it is necessary to adjust the height of the guardrail 4 on the support base 1, the handle 5 can be pulled, so that the guardrail 4 drives the slider 3 to move upward. The slider 3 will drive the arc surface of the limiting post 92 to contact the inner wall of the limiting groove 94. When the limiting post 92 is subjected to extrusion pressure, the limiting post 92 will move toward the inner wall of the slot hole 91, compressing the return spring 93. When the slider 3 moves upward and aligns with the specified limiting groove 94, due to the return spring 93 being in a compressed state, the limiting post 92 can extend into the corresponding limiting groove 94, fixing the slider 3 and fixing the guardrail 4 at the specified height. By adjusting the height of the guardrail 4, the device can be used in different environments, improving the practicability of the device.

[0026] Working principle: When it is necessary to disassemble and assemble the guardrail 4 and the support base 1, the rotary block 84 can be reversed to make the rotating rod 82 drive the clockwork spring 83 to contract. When the rotary block 84 rotates in reverse, the rotary block 84 acts on the movable rod 87, making the movable rod 87 pull the two moving blocks 86 closer to each other. The moving blocks 86 drive the limiting rods 88 to move out of the limiting holes 89, and the limiting rods 88 can be moved out of the limiting holes 89, so that the limit on the guardrail 4 can be released. The guardrail 4 can be moved upward, and the mounting block 6 can be moved out of the guide rod 7, facilitating the disassembly and assembly of the guardrail 4 and the support base 1. When it is necessary to install the guardrail 4, reverse the rotary block 84. Through the movable rod 87, the moving blocks 86 are made to approach each other, and the limiting rods 88 approach each other. The mounting block 6 can be sleeved on the guide rod 7. By loosening the rotary block 84, since the clockwork spring 83 is in a contracted state, the rotary block 84 squeezes the movable rod 87, making the movable rod 87 squeeze the two moving blocks 86 away from each other, and the limiting rods 88 extend into the limiting holes 89, facilitating the installation of the guardrail 4.

[0027] When it is necessary to adjust the height of the guardrail 4 on the support base 1, the handle 5 can be pulled, which can drive the guardrail 4 to drive the slider 3 to move upward. This will cause the arc surface of the limit post 92 driven by the slider 3 to contact the inner wall of the limit groove 94. When the limit post 92 is subjected to extrusion pressure, the limit post 92 will move toward the inner wall of the slot hole 91. When the slider 3 moves upward and aligns with the specified limit groove 94, since the return spring 93 is in a compressed state, the limit post 92 can be extended into the corresponding limit groove 94 to fix the slider 3 and fix the guardrail 4 at the specified height.

[0028] The above text has generally described the present utility model in detail. However, based on the present utility model, some modifications or improvements can be made, which are obvious to those of ordinary skill in the technical field. Therefore, modifications or improvements made without departing from the spirit of the present utility model are within the protection scope of the present utility model.
