Components and accessories are processed and manufactured in factories, transported to the construction site, and assembled and installed on site through reliable connection methods. They have the advantages of energy saving, environmental protection, and short construction period. Among them, the connection method is the key to determining the overall performance of the prefabricated building structure and needs to meet requirements such as safety, quick installation, and easy processing.

[0003] Today's prefabricated building connection forms are complex and diverse for different application scenarios. Bolt connection and welding are often used for steel structure systems. When installing a large number of bolts, the installation process is relatively cumbersome and requires professional installers to ensure the quality and performance of the node connections. In addition, the connected steel structure is difficult to disassemble and is therefore not easy to reuse.

[0004] Therefore, a detachable assembled self-locking connection structure is needed to solve the problem that the traditional steel structure connection method in the prior art is relatively cumbersome and the connected steel structure is not easy to disassemble. Utility Model Content

[0005] The purpose of the present invention is to provide a detachable assembled self-locking connection structure to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a detachable assembled self-locking connection structure, comprising a connecting sleeve and a connecting rod, a through groove being provided on the top surface of one side of the connecting sleeve, a convex slider being slidably connected inside the connecting sleeve, a sliding groove being provided on the outer wall of one side of the convex slider, a first mounting plate being fixedly connected to one side of the bottom surface of the connecting sleeve, two parallel top rods being fixedly connected to the outer wall of one side of the connecting rod, a pad being fixedly connected to one side of the bottom surface of the connecting rod, a second mounting plate being fixedly connected to the bottom surface of the pad, a clamping mechanism being provided on the connecting sleeve, and a locking structure being provided on the convex slider.

[0008] It is further worth mentioning that the locking structure includes a mounting hole opened inside one end of the T-shaped convex slider, and a limit plate is slidably connected between the two side walls of the mounting hole. A spring is fixedly connected to the center of the outer wall of one end of the limit plate, and the end of the spring away from the limit plate is fixedly connected to the end wall of the mounting hole. Limit rods are slidably penetrated at the four corners of the limit plate, and the outer walls at both ends of the limit rods are respectively fixedly connected to the two end walls of the mounting hole, and a pin is fixedly connected to the center of the outer wall of the end of the limit plate away from the spring, and the pin slides through the outer wall of one end of the convex slider.

[0009] It should be further explained that a slot cooperating with a clamping block is provided on the top surface of the connecting rod, and a pin hole cooperating with a bayonet pin is provided on the outer wall of one end of the connecting sleeve.

[0020] The present invention will be further described below with reference to the embodiments.

[0021] See also Figure 1-4 The utility model provides a detachable assembled self-locking connection structure, including a connecting sleeve 1 and a connecting rod 2. A through groove 3 is provided on the top surface of one side of the connecting sleeve 1. A convex slider 4 is slidably connected inside the connecting sleeve 1. A sliding groove 5 is provided on the outer wall of one side of the convex slider 4. A first mounting plate 8 is fixedly connected to one side of the bottom surface of the connecting sleeve 1. Two parallel top rods 9 are fixedly connected to the outer wall of one side of the connecting rod 2. A pad 10 is fixedly connected to one side of the bottom surface of the connecting rod 2. The bottom surface of the pad 10 is fixedly connected to a second mounting plate 11. A clamping mechanism 6 is provided on the connecting sleeve 1, and a locking structure 7 is provided on the convex slider 4.

[0022] Further as Figure 2 and Figure 3 As shown, it is worth mentioning that the clamping mechanism 6 includes a rotating shaft 61 rotatably connected between the inner walls at both ends of the through groove 3, and a movable plate 62 is tightly sleeved on the outer surface of the rotating shaft 61. One side of the outer wall at both ends of the movable plate 62 is fixedly connected to a sliding rod 63 that cooperates with the slide groove 5, and one side of the bottom surface of the movable plate 62 is fixedly connected to a clamping block 64.

[0023] Further as Figure 3 As shown, it is worth mentioning that the locking structure 7 includes a mounting hole 71 opened inside one end of the T-shaped convex slider 4, and a limiting plate 72 is slidably connected between the two side walls of the mounting hole 71. A spring 73 is fixedly connected to the center of the outer wall of one end of the limiting plate 72, and the end of the spring 73 away from the limiting plate 72 is fixedly connected to the end wall of the mounting hole 71. Limit rods 74 are slidably penetrated at the four corners of the limiting plate 72, and the outer walls at both ends of the limiting rod 74 are fixedly connected to the two end walls of the mounting hole 71 respectively. A pin 75 is fixedly connected to the center of the outer wall of the end of the limiting plate 72 away from the spring 73, and the pin 75 slides through the outer wall of one end of the convex slider 4.

[0024] Further as Figure 2 and Figure 4As shown, it is worth mentioning that a slot 12 cooperating with the block 64 is provided on the top surface of the connecting rod 2 , and a pin hole 13 cooperating with the bayonet pin 75 is provided on the outer wall of one end of the connecting sleeve 1 .

[0025] This solution has the following working process: when the connecting structure is in use, the connecting sleeve 1 and the connecting rod 2 are first fixed to the two steel structures that need to be connected through the first mounting plate 8 and the second mounting plate 11, and then the connecting rod 2 is moved to be inserted into the connecting sleeve 1. When the connecting rod 2 moves, it drives the two push rods 9 to move. The two push rods 9 contact the convex slider 4 inside the connecting sleeve 1. As the connecting rod 2 continues to move, the convex slider 4 moves. The slide groove 5 on the convex slider 4 cooperates with the slide rod 63, so that the movable plate 62 moves downward through the rotating shaft 61. The movable plate 62 moves downward and drives the block 64 to move downward synchronously. When the block 64 is inserted into the slot 12 on the top surface of the connecting rod 2, the connection between the connecting sleeve 1 and the connecting rod 2 is completed, and the connection between the two steel structures is realized.

[0026] When the block 64 is inserted into the slot 12, the convex slider 4 moves to the position corresponding to the pin hole 13 on the outer wall of the connecting sleeve 1, and the spring 73 inside the mounting hole 71 pushes the limit plate 72 to move on the limit rod 74. The movement of the limit plate 72 drives the latch pin 75 to move, so that the latch pin 75 is inserted into the pin hole 13 that matches it, thereby locking the convex slider 4. When the connecting sleeve 1 is separated from the connecting rod 2 when needed, press the latch pin 75 to disengage it from the pin hole 13, and then push the protrusion of the convex slider 4. The convex slider 4 moves and pushes the movable plate 62 upward, so that the block 64 is separated from the slot 12, thereby separating the connecting sleeve 1 from the connecting rod 2.

[0027] According to the above working process, it can be known that: through the action of the clamping mechanism 6, when the connecting rod 2 pushes the convex slider 4 to move, the slide rod 63 cooperates with the rotating shaft 61 to make the movable plate 62 move downward, thereby driving the clamping block 64 to move downward. When the clamping block 64 is inserted into the clamping groove 12 on the top surface of the connecting rod 2, the connection between the connecting sleeve 1 and the connecting rod 2 is completed, thereby realizing the connection of the two steel structures. The operation is simple and effectively avoids the more cumbersome problems of traditional steel structure connection methods.

[0028] When the locking structure 7 is adjusted, the block 64 is inserted into the slot 12, and the spring 73 in the mounting hole 71 at one end of the convex slider 4 pushes the limit plate 72 to move. The movement of the limit plate 72 causes the latch pin 75 to move and be inserted into the pin hole 13, thereby locking the convex slider 4. Conversely, pressing the latch pin 75 disengages it from the pin hole 13, pushing the convex slider 4 to move the block 64 out of the slot 12, thereby realizing the disassembly of the connected steel structure and effectively avoiding the problem that the connected steel structure is difficult to disassemble.

[0029] Further as Figure 1 As shown, it is worth mentioning that the raised portion of the convex slider 4 is slidably connected to the inner wall of the through groove 3, which is convenient for pushing the convex slider 4 when releasing the lock, thereby separating the connecting sleeve 1 from the connecting rod 2. The top surfaces of the first mounting plate 8 and the second mounting plate 11 are provided with multiple fixing holes, which are convenient for installing the device on the steel structure that needs to be connected.

[0030] Further as Figure 2 and Figure 3 As shown, it is worth noting that the width of the movable plate 62 is smaller than the width of the through slot 3, which facilitates the movable plate 62 to move in the through slot 3, and the end of the pin 75 away from the limiting plate 72 is set to an arc shape to facilitate better pressing of the pin 75.

[0031] In summary: when the connection structure is in use, the connecting sleeve 1 and the connecting rod 2 are first fixed to the two steel structures that need to be connected through the first mounting plate 8 and the second mounting plate 11, and then the connecting rod 2 is moved to be inserted into the connecting sleeve 1. When the connecting rod 2 moves, it drives the two push rods 9 to move. The two push rods 9 contact the convex slider 4 inside the connecting sleeve 1. As the connecting rod 2 continues to move, the convex slider 4 moves, and the slide groove 5 on the convex slider 4 cooperates with the slide rod 63, so that the movable plate 62 moves downward through the rotating shaft 61. The downward movement of the movable plate 62 drives the block 64 to move downward synchronously. When the block 64 is inserted into the groove 12 on the top surface of the connecting rod 2, the connection between the connecting sleeve 1 and the connecting rod 2 is completed, and the connection of the two steel structures is realized, which effectively avoids the more cumbersome problems of traditional steel structure connection methods.

[0032] When the locking plate 72 is in the state of being inserted into the slot 12, the convex slider 4 moves to the position corresponding to the pin hole 13 on the outer wall of the connecting sleeve 1, and the spring 73 inside the mounting hole 71 pushes the limit plate 72 to move on the limit rod 74. The movement of the limit plate 72 drives the locking pin 75 to move, so that the locking pin 75 is inserted into the pin hole 13 matched with it, thereby locking the convex slider 4. When the connecting sleeve 1 is separated from the connecting rod 2 when needed, the locking pin 75 is pressed to disengage it from the pin hole 13, and then the protrusion of the convex slider 4 is pushed. The convex slider 4 moves and pushes the movable plate 62 upward, so that the block 64 is separated from the slot 12, realizing the separation of the connecting sleeve 1 and the connecting rod 2, thereby realizing the disassembly of the connected steel structure, effectively avoiding the problem that the connected steel structure is difficult to disassemble.
