Description

Technical Field

[0001] This utility model relates to the technical field of fastening devices for connecting container houses, and in particular to a fastening device for connecting prefabricated container houses. Background Technology

[0002] Container houses are widely used due to their characteristics such as easy movement, convenient construction, stability, good shock resistance, light weight, and easy assembly and disassembly. Container houses are usually made up of one or more containers. When assembling multiple containers, connecting devices are needed to connect adjacent containers.

[0003] Regarding the prior art patent CN211851068U, which discloses a fastening device for connecting prefabricated container houses, the device includes a connecting mother body and a connecting daughter body connecting adjacent containers. The connecting mother body has an installation groove and a cavity. A return spring and a T-shaped rod are provided in the installation groove. The T-shaped rod includes an integrally connected head and a rod portion. The head is located in the installation groove and connected to the return spring. The end of the rod portion away from the head penetrates the groove wall of the installation groove into the cavity. A locking structure is provided on the rod portion located in the cavity. A connecting block is provided on the connecting daughter body, and the connecting block is adapted to the locking structure. This invention utilizes the connecting block on the connecting daughter body to insert into the cavity. The existing design utilizes a locking structure to fix the connecting block. Specifically, when the wedge-shaped structure of the connecting block enters the cavity, it pushes the locking plate towards the T-shaped rod. Simultaneously, the second slider moves on the locking plate, which in turn pushes the first slider away from the head of the T-shaped rod. The head of the T-shaped rod then compresses the return spring towards the rod. When the connecting block and the locking plate are engaged, the return spring acts on the head of the T-shaped rod, causing the locking plate and the second slider to return to their original positions. However, when two container houses are spliced ​​together, they are only fixed with bolts. Over time, the bolts can rust and fall off, potentially causing the two container houses to separate, affecting the stability of the installation, which has certain drawbacks.

[0004] Therefore, when assembling two existing container houses, the current method of fixing them with bolts alone can lead to bolts rusting and falling off over time, potentially causing the two container houses to separate and affecting the stability of the installation. To address this issue, a fastening device for connecting prefabricated container houses can be designed. This reinforced fastening device can enhance the fixing effect between the two container houses, extend their service life, and strengthen the stability of the assembled houses. Utility Model Content

[0005] To overcome the problem that when two container houses are assembled together, they are only fixed with bolts, which can rust and fall off over time, potentially causing the two container houses to separate and affecting the stability of the installation.

Reinforcing plates that insert into the reinforcing slots are fixedly installed at both the upper and lower ends of the connecting block. Through holes are provided inside the reinforcing plates, through which the rods and reinforcing plates pass.

[0007] Preferably, by inserting the fastening structure into the gap between the first and second houses, the connecting blocks on the left and right sides of the fastening structure are squeezed by the outer wall, causing the telescopic sleeve rod and telescopic cylinder on one side of the connecting block to extend and retract, and the connecting block is inserted into the fixing groove. At the same time, the reinforcing plates at the upper and lower ends of the connecting block are inserted into the reinforcing slot for fixation.

[0008] Preferably, both the first and second houses are fixedly provided with bases on their lower ends, and the four feet on the lower ends of the bases are fixedly provided with mounting structures.

[0024] Please see Figures 1-6 This utility model provides an embodiment: a fastening device for connecting prefabricated container houses, including a first house 1, a second house 2 on one side of the first house 1, and a fixing groove 12 on the surface of one side of the second house 2. The fixing groove 12 has a reinforcing slot 13 at both its upper and lower ends. A protrusion is fixedly installed inside the fixing groove 12, and movable grooves 14 are opened inside both the upper and lower ends of the protrusion. A first spring 16 is installed inside each of the two movable grooves 14, and a plug rod 15 is installed at one end of each of the two first springs 16. Fastening structures 7 are provided at both the upper and lower ends of the front ends of the first house 1 and the second house 2. An extension fixing plate 8 located between the first house 1 and the second house 2 is fixedly installed on the rear end face of the fastening structure 7. A telescopic cylinder 19 is installed through the inside of the plate 8. Telescopic sleeves 17 are installed on both the left and right sides inside the telescopic cylinder 19. A second spring 18 is sleeved on the outside of each of the two telescopic sleeves 17. A connecting block 9 that is inserted into the fixing groove 12 is fixedly installed on one side of each of the two telescopic sleeves 17. A reinforcing plate 10 that is inserted into the reinforcing slot 13 is fixedly installed at both the upper and lower ends of the connecting block 9. A through hole 11 is opened inside the reinforcing plate 10. The insert rod 15 and the reinforcing plate 10 pass through the through hole 11. Through the squeezing action of the insert rod 15 and the first spring 16 below, after the reinforcing plate 10 is fully inserted into the reinforcing slot 13, the insert rod 15 pops out and passes through the through hole 11 under the anti-loosening effect of the first spring 16 to fix it.

[0025] Please see Figures 1-2 In this embodiment, a base is fixedly installed on the lower end face of both the first house 1 and the second house 2. An installation structure is fixedly installed on the four end feet of the lower end face of the base. An installation block 4 is fixedly installed on the upper end face of the second house 2. A positioning groove is opened inside the installation block 4. An L-shaped positioning plug 3 is fixedly installed on the upper end face of the first house 1 and inserted into the positioning groove. The first house 1 and the second house 2 are aligned, and the L-shaped positioning plugs 3 at both ends of the upper end face of the first house 1 are inserted into the positioning groove inside the second house 2 for fixation. Finally, the fastening bolt 5 is engaged and inserted into the threaded hole 6 for reinforcement. The fastening structure 7 is inserted into the gap between the first house 1 and the second house 2. At the same time, the connecting plugs 9 on the left and right sides of the fastening structure 7 are squeezed by the outer wall.

[0026] Please see Figures 2-5In this embodiment, the L-shaped positioning plug 3 has a reinforcement hole inside, the mounting block 4 has a threaded hole 6 inside, and a fastening bolt 5 is engaged and passed through the threaded hole 6. The surfaces of the first house 1 and the second house 2 have reinforcement screw holes. The fastening structure 7 has a mounting hole inside, and a threaded rod is engaged and inserted into the reinforcement screw hole inside the mounting hole. A limit plate is provided between the plug rod 15 and the first spring 16. The diameter of the limit plate is smaller than the opening size of the movable groove 14, so that the telescopic sleeve 17 and the telescopic cylinder 19 on one side of the connecting block 9 can extend and retract. At the same time, the second spring 18 sleeved on the outside of the telescopic sleeve 17 is compressed. When the connecting block 9 reaches the fixing groove 12 opened on the outer wall of the first house 1 and the second house 2, it is prevented from being released by the second spring 18, so that the connecting block 9 is locked into the fixing groove 12. At the same time, the reinforcement plug plates 10 at the upper and lower ends of the connecting block 9 are inserted into the reinforcement slots 13 inside the fixing groove 12 for fixation.

[0027] During operation, the first house 1 and the second house 2 are aligned. The L-shaped positioning blocks 3 at both ends of the upper front of the first house 1 are inserted into the positioning grooves inside the second house 2 for fixation. Finally, the fastening bolts 5 are engaged and inserted into the threaded holes 6 for reinforcement. The fastening structure 7 is then inserted into the gap between the first house 1 and the second house 2. Simultaneously, the connecting blocks 9 on both sides of the fastening structure 7 are pressed by the outer wall, causing the telescopic sleeve 17 and telescopic cylinder 19 on one side of the connecting block 9 to extend and retract. At the same time, the second spring 18 sleeved on the outside of the telescopic sleeve 17 is compressed. When the connecting block 9 reaches the gap between the first house 1 and the second house 2... When the fixing groove 12 is opened in the outer wall of the second house 2, it is popped out by the second spring 18 to prevent loosening, so that the connecting block 9 is inserted into the fixing groove 12. At the same time, the reinforcing plates 10 at the upper and lower ends of the connecting block 9 are inserted into the reinforcing slots 13 inside the fixing groove 12 for fixation. When they are inserted, the reinforcing plates 10 press the rod 15 downward, so that the first spring 16 below the rod 15 is compressed. After the reinforcing plates 10 are fully inserted into the reinforcing slots 13, the rod 15 pops out under the anti-loosening of the first spring 16, so that it passes through the through hole 11 opened in the reinforcing plates 10 for fixation, thereby strengthening the connection between the first house 1 and the second house 2.

[0028] Through the above steps, the two L-shaped positioning blocks 3 on the upper surface of the first house 1 are inserted into the positioning groove inside the second house 2 for fixation. Finally, the fastening bolts 5 are engaged and inserted into the threaded holes 6 to strengthen the fixation. This solves the problem that when two container houses are spliced ​​and installed, they are only fixed by bolts. Over time, the bolts will rust and fall off, which may cause the two container houses to separate and affect the stability of the installation.
