[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] A detachable steel structure fence includes a first fixing plate, a second fixing plate on top of the first fixing plate, first connecting columns evenly fixed on the top of the first fixing plate, a second connecting column fixed on the bottom of the second fixing plate at a position corresponding to the first connecting column, the bottom end of the second connecting column slidably connected to the first connecting column, a rotating shaft rotatably connected inside the second connecting column, a brake block fixed at the bottom of the rotating shaft, the brake block slidably connected to the first connecting column, a second bevel gear fixed at the top of the rotating shaft inside the second fixing plate, a rotary drive motor fixed inside the second fixing plate, the output end of the rotary drive motor connected to the rotating shaft, a first bevel gear fixed on the outside of the rotating shaft, and the bottom of the first bevel gear meshing with the second bevel gear.

[0008] In a preferred embodiment of the detachable steel structure fence provided by this utility model, an auxiliary column is slidably connected between the first fixing plate and the second fixing plate at a position intersecting with the first connecting column.

[0009] In a preferred embodiment of the detachable steel structure fence provided by this utility model, a sliding groove is provided inside the top of the first connecting column, and the sliding groove is slidably connected to the brake block.

[0010] In a preferred embodiment of the detachable steel structure enclosure provided by this utility model, a rotating groove is provided inside the first connecting column and at the bottom of the sliding groove, and the rotating groove is connected to the sliding groove.

[0011] In a preferred embodiment of the detachable steel structure fence provided by this utility model, a second ear plate is fixed to the top of one end of the first fixing plate and the second fixing plate, and a first ear plate is fixed to the bottom of the other end of the first fixing plate and the second fixing plate. A splicing mechanism is installed between the first ear plate and the second ear plate.

[0012] As a preferred embodiment of the detachable steel structure fence provided by this utility model, the splicing mechanism includes a sliding body, an adjusting bolt, a lifting column, an anti-detachment plate, a telescopic block, a pressing frustum, and a limiting column. The sliding body is slidably connected to both the first ear plate and the second ear plate. Telescopic blocks are slidably connected to the interior of both ends of the bottom of the sliding body. An anti-detachment plate is fixed at one adjacent end of the two telescopic blocks inside the sliding body. A lifting column is slidably connected inside the sliding body. An adjusting bolt is rotatably connected to the interior of the top of the sliding body. The outer side of the bottom end of the adjusting bolt is slidably connected to the lifting column. A pressing frustum is fixed at the bottom of the lifting column. A limiting column is fixed at the bottom of the pressing frustum.

[0013] It is clear without a doubt that the technical solution described above in this application can solve the technical problem that this application aims to address.

[0014] At the same time, through the above technical solutions, this utility model has at least the following beneficial effects:

[0015] This utility model provides a detachable steel structure fence. Through the cooperation of a first fixed plate, a second fixed plate, a first connecting column, a second connecting column, and a splicing mechanism, the first connecting column and the second connecting column can be spliced ​​together, thereby connecting the first fixed plate and the second fixed plate. High-density protection is achieved through the addition of auxiliary columns. At the same time, the fence can be assembled through the splicing mechanism according to the length requirements, so that different lengths can be adjusted.

[0016] Through the cooperation of the sliding groove, the rotating groove and the brake block, the second fixing plate enters the sliding first connecting post through the second connecting post at the top of the first fixing plate. At this time, the brake block rotates inside the rotating groove to restrict the separation of the first connecting post from the second connecting post.

[0017] By cooperating with the first ear plate, the second ear plate, and the sliding body, when connecting two adjacent fences, the first ear plate and the second ear plate are staggered, and the sliding body enters the corresponding first ear plate and the corresponding second ear plate to fix the two adjacent fences.

[0018] By combining the lifting column, the anti-detachment plate, and the telescopic block, the lifting column can descend inside the sliding body. The compression truncated cone squeezes the anti-detachment plate, causing the anti-detachment plate to drive the telescopic block out of the sliding body. Thus, the telescopic block is located at the bottom of the first ear plate, preventing the sliding body from rising and detaching. Attached Figure Description

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0029] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0030] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0031] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0032] Example 1

[0033] Reference Figures 1-4A detachable steel structure fence includes a first fixing plate 1, a second fixing plate 2 on the top of the first fixing plate 1, first connecting columns 5 evenly distributed and fixed on the top of the first fixing plate 1, and a second connecting column 6 fixed at the bottom of the second fixing plate 2 at a position corresponding to the first connecting column 5. The bottom end of the second connecting column 6 is slidably connected to the first connecting column 5, so that the second fixing plate 2 can be pre-positioned at the top of the first fixing plate 1 through the slidable connection between the first connecting column 5 and the second connecting column 6. An auxiliary column 7 is slidably connected between the first fixing plate 1 and the second fixing plate 2 at a position intersecting with the first connecting column 5. Thus, the protective density of the fence can be increased by adding the auxiliary column 7, and the number of auxiliary columns 7 can be changed as needed.

[0034] A rotating shaft 10 is rotatably connected inside the second connecting post 6. A brake block 11 is fixed to the bottom of the rotating shaft 10, and the brake block 11 can be rectangular or the like. The brake block 11 is slidably connected to the first connecting post 5, so that after the brake block 11 enters the interior of the first connecting post 5, the rotation of the brake block 11 makes the first connecting post 5 and the second connecting post 6 inseparable. A second bevel gear 15 is fixed to the top of the rotating shaft 10 and inside the second fixed plate 2. A rotary drive motor 12 is fixed inside the second fixed plate 2. The output end of the rotary drive motor 12 is connected to a rotating shaft 13. A first bevel gear 14 is fixed to the outside of the rotating shaft 13, and the bottom of the first bevel gear 14 meshes with the second bevel gear 15, so that the rotation of the rotating shaft 13 drives the second bevel gear 15 to rotate through the first bevel gear 14, and the second bevel gear 15 drives the rotating shaft 10 to drive the brake block 11 to rotate.

[0035] Preferably, a sliding groove 8 is provided inside the top of the first connecting post 5. The shape of the sliding groove 8 is the same as that of the brake block 11, and the sliding groove 8 is slidably connected to the brake block 11. This allows the brake block 11 to move up and down inside the sliding groove 8 when it enters the sliding groove 8, but prevents it from rotating or tilting inside the sliding groove 8. A rotating groove 9 is provided inside the first connecting post 5 at the bottom of the sliding groove 8, and the rotating groove 9 is connected to the sliding groove 8. The diameter of the rotating groove 9 is greater than the length of the brake block 11, allowing the brake block 11 to rotate inside the rotating groove 9. After the brake block 11 rotates inside the rotating groove 9, it cannot enter the sliding groove 8 from the inside of the rotating groove 9 unless the brake block 11 rotates to the same direction as the sliding groove 8.

[0036] In this embodiment, each structure has its own service life. In actual manufacturing and application, the corresponding structure made of different materials can be replaced according to the needs of use.

[0037] In this embodiment, the motor is a self-locking motor, which can drive the connected structure to rotate normally when it is powered on and working. When the motor stops working, it can prevent the connected structure from rotating through its self-locking function.

[0038] In this embodiment, the rotary drive motor 12 can be powered by an external power source connected by a wire. In other embodiments, the rotary shaft 13 can be extended out of the first ear plate 3, and the tool can drive the rotary shaft 13 to rotate by means of the outside of the second fixed plate 2.

[0039] In this embodiment, at least the first fixing plate 1, the second fixing plate 2, the first connecting column 5, the second connecting column 6, and the auxiliary column 7 are all made of steel.

[0040] The usage process of the detachable steel structure fence provided by this utility model is as follows: In use, the second fixing plate 2 can be slidably connected to the first connecting column 5 at the bottom of the second connecting column 6 on the top of the first fixing plate 1, so as to pre-position the positions of the first fixing plate 1 and the second fixing plate 2. At the same time, when the second connecting column 6 enters the interior of the first connecting column 5, the brake block 11 enters the interior of the rotating groove 9 through the sliding groove 8. Then, the operation of the rotation drive motor 12 drives the rotating shaft 13 to rotate, and the rotation of the rotating shaft 13 drives the first bevel gear 14 to rotate. The rotation of the first bevel gear 14 drives the rotating shaft 10 to rotate through the meshing second bevel gear 15. The rotating shaft 10 drives the brake block 11 to rotate inside the rotating groove 9, so that the direction of the brake block 11 after rotation is different from that of the sliding groove 8. At this time, the second connecting column 6 and the first connecting column 5 cannot be separated.

[0041] Example 2

[0042] Reference Figures 1-7 A detachable steel structure fence, wherein a second ear plate 4 is fixed to the top of one end of the first fixed plate 1 and the second fixed plate 2, and a first ear plate 3 is fixed to the bottom of the other end of the first fixed plate 1 and the second fixed plate 2, and the second ear plate 4 is higher than the first ear plate 3, so that when two adjacent fences are connected, the first ear plate 3 is lower than the second ear plate 4, so that the corresponding first ear plate 3 and second ear plate 4 are staggered. A splicing mechanism is installed between the first ear plate 3 and the second ear plate 4, so that the corresponding first ear plate 3 and second ear plate 4 cannot be separated through the splicing mechanism.

[0043] The splicing mechanism includes a sliding body 16, an adjusting bolt 17, a lifting column 18, an anti-detachment plate 19, a telescopic block 20, a pressing frustum 21, and a limiting column 22. The sliding body 16 is slidably connected to the first ear plate 3 and the second ear plate 4, so that the sliding body 16 can slide down into the first ear plate 3 and the second ear plate 4, and can rise and detach. The telescopic blocks 20 are slidably connected to the inside of both ends of the bottom of the sliding body 16, so that when the telescopic blocks 20 extend out of the sliding body 16, they are located at the bottom of the first ear plate 3. At this time, the sliding body 16 cannot detach from the first ear plate 3 and the second ear plate 4. An anti-detachment plate 19 is fixed at one of the adjacent ends of the two telescopic blocks 20 and inside the sliding body 16, so that the movement of the anti-detachment plate 19 drives the movement of the telescopic blocks 20, and at the same time, the anti-detachment plate 19 prevents the telescopic blocks 20 from detaching from the sliding body 16.

[0044] The sliding body 16 has a sliding connection to a lifting column 18 inside. The top of the sliding body 16 has a rotating connection to an adjusting bolt 17. The outer side of the bottom end of the adjusting bolt 17 is slidably connected to the lifting column 18, so that the rotation of the adjusting bolt 17 can drive the lifting column 18 to rise and fall inside the sliding body 16. The lifting column 18 is guided by a guide column that is slidably connected to the adjusting bolt 17 at the top, and the top of the guide column is fixed to the sliding body 16, so that the lifting column 18 can only be adjusted up and down inside the sliding body 16. The bottom of the lifting column 18 is fixed with a pressing frustum 21, so that the bottom diameter of the pressing frustum 21 is smaller than the top diameter of the pressing frustum 21. The bottom of the pressing frustum 21 is fixed with a limit post 22, so that the descent of the lifting column 18 causes the telescopic block 20 to extend out of the sliding body 16 through the pressing of the anti-detachment plate 19 by the pressing frustum 21.

[0045] The usage process of the detachable steel structure fence provided by this utility model is as follows: When two adjacent fences need to be connected, the corresponding first ear plate 3 and the corresponding second ear plate 4 in the two adjacent fences are staggered. Then, the sliding body 16 slides down into the first ear plate 3 and the corresponding second ear plate 4. At this time, the adjusting bolt 17 can be rotated on the top of the sliding body 16 with a tool. The rotation of the adjusting bolt 17 drives the lifting column 18 to descend inside the sliding body 16. The descent of the lifting column 18 squeezes the anti-detachment plate 19 through the extrusion platform 21. The movement of the anti-detachment plate 19 drives the telescopic block 20 to extend out of the sliding body 16. At this time, the telescopic block 20 is located at the bottom of the corresponding first ear plate 3, so that the first ear plate 3 and the second ear plate 4 cannot be separated. At the same time, the limiting column 22 can extend out of the bottom of the sliding body 16 for indication.

[0046] When separation is required, the adjusting bolt 17 is rotated in the opposite direction, causing the lifting column 18 to rise inside the sliding body 16. After the sliding body 16 rises, it causes the pressing platform 21 and the limiting column 22 to rise, so that the pressing platform 21 does not press the anti-detachment plate 19. At this time, the telescopic block 20 can be manually pressed to allow the telescopic block 20 to drive the anti-detachment plate 19 into the sliding body 16. The limiting column 22 limits the telescopic block 20 to prevent it from disengaging from the corresponding sliding connection position when it enters the sliding body 16, thus not affecting the next use.

These preferred embodiments do not exhaustively describe all details, nor do they limit the present utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of the present utility model, thereby enabling those skilled in the art to better understand and utilize it.
