Description

Technical Field

[0001] This utility model relates to the field of building installation technology, specifically a modular steel structure quick-assembly connection device. Background Technology

[0002] Modular steel structure refers to dividing a steel structure building into several independent frame modules. These modules are prefabricated in the factory, and only a small amount of connection work is required on site.

[0003] Chinese patent CN221001438U discloses a modular steel structure building connection device, including a support column, a support block, a steel structure body, and a limiting plate. The support block is installed on the top of the support column, and the steel structure body is located in the inner cavity of the support block. By using the steel structure body, support block, limiting groove, limiting rod, locking rod, limiting block, locking block, and fixing mechanism in coordination, the steel structure body is placed at the bottom of the support block and pressed down. The steel structure body enters the inner cavity of the limiting groove, and the steel structure body drives the limiting rod and locking rod to move. The limiting rod and locking rod enter the inner cavities of the limiting block and locking block, respectively. Then, the limiting rod is fixed by the fixing mechanism to complete the installation. This solves the problem that most existing steel structure connection components use multiple bolts and support columns for connection, which requires multiple people and corresponding tools, making the process too complicated.

[0004] In the above technical solution, during installation, the button must be pressed first to push the fixed rod to move, and then the steel structure body is placed on the support block. After the limiting rod is inserted into the limiting hole, the button is released, and the fixed rod is used to limit the limiting rod. This step-by-step operation is difficult to complete with one hand under high altitude, narrow space or heavy load conditions, and the installation efficiency is still low.

[0005] Based on this, this utility model proposes a modular steel structure quick-assembly connection device. Utility Model Content

[0006] To address the aforementioned technical problems, this utility model proposes a modular steel structure quick-assembly connection device, which enables the rapid installation and fixing of the steel structure body through the cooperation of limiting columns, slots, and blocks, and enables the rapid disassembly and separation of the steel structure body through the cooperation of sliding columns and rotating rods, greatly improving the connection or disassembly speed of the device.

[0007] The technical solution to achieve the purpose of this utility model is: a modular steel structure quick-assembly connection device, including a support block, on which an installation groove is formed, and a steel structure body is slidably connected in the installation groove, and further including:

[0008] The three limiting holes are formed on the support block. Three limiting posts are fixedly connected to the steel structure body. The limiting posts are adapted to the limiting holes. Three slots are formed on the three limiting posts. A fixing sleeve is fixedly connected to the support block. Three sliding grooves are formed in the fixing sleeve. Three locking blocks are slidably connected in the three sliding grooves. The locking blocks are adapted to the locking grooves.

[0009] Preferably, a sliding column is slidably connected inside the fixed sleeve, and three rotating rods are rotatably connected to the sliding column, with the three rotating rods respectively rotatably connected to three locking blocks.

[0010] Preferably, the sliding column has a through hole that penetrates the sliding column.

[0011] Preferably, a fixing plate is fixedly connected to the sliding column, and multiple springs are fixedly connected to the fixing plate, with the multiple springs fixedly connected to the fixing sleeve.

[0012] Preferably, two tie rods are fixedly connected to the fixing plate.

[0013] Preferably, the multiple springs are arranged in a circular array with the center of the fixed plate as the center, and the two pull rods are symmetrical about the fixed plate.

[0014] Compared with existing technologies, the significant advantages of this invention are:

[0015] Firstly, in this utility model, through the inclined surface design of the limiting column and the card block, when the steel structure body is inserted into the installation groove, the limiting column is automatically guided to squeeze the card block inward. After the card block moves to the corresponding position of the card slot, the spring drives the sliding column to rebound, and the linkage rotating rod pushes the card block into the card slot, realizing "one-insertion lock".

[0016] Secondly, in this utility model, disassembly only requires pulling down the lever with one hand, which moves the sliding column down to compress the spring. Through the lever action of the rotating rod, the three locking blocks are simultaneously retracted into the sliding groove, instantly releasing the constraint on the limiting column. This allows the steel structure body to be quickly disassembled, improving the practicality of the device. Attached Figure Description

[0024] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0025] This utility model provides an improved modular steel structure quick-assembly connection device. The technical solution of this utility model is as follows:

[0026] like Figures 1-4 As shown, a modular steel structure quick-assembly connection device includes a support block 1, on which an installation groove 2 is formed. The cross-section of the installation groove 2 is "T"-shaped. A steel structure body 4 is slidably connected within the installation groove 2. The device also includes:

[0027] Three limiting holes 3 are provided on the support block 1. Three limiting posts 5 are fixedly connected to the steel structure body 4. The limiting posts 5 are adapted to the limiting holes 3. The three limiting posts 5 are arranged in a circular array with the center of the fixing sleeve 7 as the center. Three slots 6 are provided on the three limiting posts 5 respectively. The slots 6 are located on the side of the limiting post 5 close to the fixing sleeve 7. The fixing sleeve 7 is fixedly connected to the support block 1. Three sliding grooves 8 are provided in the fixing sleeve 7. Three locking blocks 9 are slidably connected in the three sliding grooves 8 respectively. The locking blocks 9 are adapted to the slots 6. Through the inclined surface cooperation design of the limiting posts 5 and the locking blocks 9, when the steel structure body 4 is inserted into the installation groove 2, the limiting posts 5 are automatically guided to squeeze the locking blocks 9 inward. After the locking blocks 9 move to the corresponding position of the slots 6, the spring 14 drives the sliding post 10 to rebound, and the linkage rotating rod 11 pushes the locking blocks 9 into the slots 6 to achieve "one-insertion locking".

[0028] Furthermore, such as Figure 2 and Figure 3 As shown, a sliding column 10 is slidably connected inside the fixed sleeve 7. The cross-section of the sliding column 10 is convex. Three rotating rods 11 are rotatably connected to the sliding column 10, and the three rotating rods 11 are rotatably connected to three locking blocks 9 respectively.

[0029] Furthermore, such as Figure 2 and Figure 3 As shown, a through hole 12 is provided inside the sliding column 10. The through hole 12 passes through the sliding column 10 and is used to balance the air pressure inside and outside the fixed sleeve 7 to avoid affecting the movement of the sliding column 10.

[0030] Furthermore, such as Figures 1-4 As shown, a fixed plate 13 is fixedly connected to the sliding column 10. The diameter of the fixed plate 13 is equal to the diameter of the fixed sleeve 7. Multiple springs 14 are fixedly connected to the fixed plate 13 and are fixedly connected to the fixed sleeve 7.

[0031] Furthermore, such as Figure 2 and Figure 3 As shown, two pull rods 15 are fixedly connected to the fixed plate 13, and the sliding column 10 is moved by pulling the pull rods 15.

[0032] Furthermore, such as Figure 2 and Figure 3 As shown, multiple springs 14 are arranged in a circular array with the center of the fixing plate 13 as the center, and two tie rods 15 are symmetrical about the fixing plate 13. The springs 14 enable the locking block 9 to automatically reset, thereby realizing the rapid installation of the steel structure body 4.

[0033] The specific working method is as follows: Insert the steel structure body 4 into the installation groove 2, so that the limiting post 5 on it is simultaneously embedded into the limiting hole 3. When the limiting post 5 passes through the limiting hole 3, it will meet the inclined surface of the locking block 9, first pressing the locking block 9 into the sliding groove 8. Since the rotating rod 11 is rotatably connected to the locking block 9, the rotating rod 11 rotates with the movement of the locking block 9, pushing the sliding post 10 down and stretching the spring 14. After the locking groove 6 meets the locking block 9, the limiting post 5 no longer presses the locking block 9, the spring 14 returns to its original position, and drives the sliding post 10 up, using the rotating rod 11. Push the locking block 9 to move outward, so that the locking block 9 is embedded in the locking groove 6, and fix the limiting post 5, thereby completing the installation and fixation of the steel structure body 4. When it is necessary to disassemble the steel structure body 4, pull the pull rod 15, which drives the sliding post 10 to move down. Since the rotating rod 11 is rotatably connected to the sliding post 10, the rotating rod 11 rotates with the movement of the sliding post 10, pull the locking block 9 to be embedded in the sliding groove 8, release its restriction on the limiting post 5, and then the steel structure body 4 and the limiting post 5 can be taken out from the support block 1, completing the disassembly of the steel structure body 4.

[0034] The technical means disclosed in this utility model are not limited to those described above, but also include technical solutions composed of equivalent substitutions of the above technical features. Matters not covered in this utility model are common knowledge to those skilled in the art.
