A prefabricated component connection structure Technical Field
[0001] This utility model belongs to the field of prefabricated component technology, and specifically relates to a prefabricated component connection structure. Background Technology
[0002] Precast components refer to steel, wood, or concrete components prefabricated in a factory or on-site according to design specifications. During use, precast components often require vertical connection structures to connect them for ease of use. A search revealed application number "CN202220073436.3" which discloses a "vertical connection structure between precast components of assembled buildings." This document describes how "by setting an expansion waterproof strip, the sealing between the insert and the slot is improved, preventing water from seeping into the main and secondary plates; the main and secondary sealing rings cooperate to improve the waterproof performance of the main and secondary plates; and the main and secondary sealing rings are connected by inserting a clamping rod into the slot." While the expansion waterproof strip improves the sealing between the insert and the slot, and the main and secondary sealing rings do indeed improve the waterproof performance, and the clamping rod connects the main and secondary sealing rings, the above-mentioned document still has the following problems in actual use:
[0003] In actual use, the inability to establish a fast and stable connection leads to a decrease in work efficiency.
[0004] Therefore, providing a structure that can achieve a fast and stable connection is of great practical value. Summary of the Invention
[0005] The purpose of this utility model is to provide a prefabricated component connection structure to solve the above-mentioned technical problems.
[0006] This utility model provides a prefabricated component connection structure, including a first prefabricated component and a fast and stable connection assembly.
[0007] The bottom of the first preform is movably connected to the second preform. Both sides of the first and second preforms are provided with M-shaped grooves, and the top and bottom of the M-shaped grooves are provided with connecting grooves.
[0008] The quick and stable connection assembly includes two connecting rods movably connected inside an M-shaped groove. A fixing plate is provided on one side of each connecting rod. A protective box is located in the middle of one side of the fixing plate. Two auxiliary slots are formed on the top of the protective box. Two limiting rods are provided on the inner wall of the protective box. Moving blocks are slidably connected to the outer walls of the two limiting rods. Two hinge seats are provided at the top and bottom of each moving block. Auxiliary blocks are hinged inside each of the two hinge seats. Connecting rods are provided at the ends of several auxiliary blocks. Connecting seats are hinged in the middle of each connecting rod. The end of the connector is fixedly connected to the protective box. A plug is provided at the end of the connecting rod. A lead screw is rotatably connected to one side of the inner wall of the protective box. The outer wall of the lead screw is threadedly connected to the moving block. A rotating head is provided on one side of the lead screw, passing through the protective box and the fixing plate. Two damping rod springs are provided at the bottom of one of the connecting slots. Limiting heads are provided at the bottom of the two damping rod springs. A slot is opened at the bottom of the limiting head. The slot is inserted and connected to the plug. The top of the other connecting slot has the same structure. Limiting slots are opened in the middle of both connecting rods.
[0009] In one embodiment of this utility model, several of the limiting heads are all made of chromium metal.
[0010] In one embodiment of this utility model, several of the plugs are cast from tungsten metal.
[0011] In one embodiment of this utility model, the outer surface of the rotating ring is provided with a plurality of anti-slip textures.
[0012] In one embodiment of this utility model, both fixing plates are made of titanium alloy.
[0013] In one embodiment of this utility model, the outer walls of several of the limiting heads and plugs are coated with a wear-resistant coating.
[0014] Compared with the prior art, the beneficial effects of this utility model are:
[0015] The fixed plate allows users to easily insert the connecting rod and protective box into the M-shaped groove by holding the plate. When the connecting rod enters the M-shaped groove, it will first contact the limiting head. The limiting head will transmit force to the damping rod spring, which will then contract, allowing the connecting rod to continue moving. Once the connecting rod is fully inserted into the M-shaped groove, the limiting groove will contact the limiting head, at which point the limiting head will engage with the limiting groove on the connecting rod for initial fixation. At this point, the user can rotate the rotating head to drive the lead screw to rotate. The rotation of the lead screw will engage with the limiting rod through the external thread, thereby moving the moving block. The moving block will then move the connecting rod through the connecting seat via the hinge seat and auxiliary block, which will in turn drive the plug to insert into the slot in the limiting head for fixation, thus achieving a quick and stable connection.

[0023] Example
[0024] Please refer to Figures 1-4, a prefabricated component connection structure including a first prefabricated component 100 and a fast and stable connection assembly 200.
[0025] Please refer to Figure 1 for details. The bottom of the first preform 100 is movably connected to the second preform 110. Both sides of the first preform 100 and the second preform 110 are provided with M-shaped grooves, and the top and bottom of the M-shaped grooves are provided with connecting grooves.
[0026] Please refer to Figures 1-4. The quick and stable connection assembly 200 includes two connecting rods 210 movably connected inside the M-shaped groove. A fixing plate 220 is provided on one side of the two connecting rods 210. A protective box 230 is provided in the middle of one side of the fixing plate 220. Two auxiliary slots are opened on the top of the protective box 230. Two limiting rods 240 are provided on the inner wall of the protective box 230. Moving blocks 250 are slidably connected to the outer walls of the two limiting rods 240. Two hinge seats 260 are provided at the top and bottom of the moving blocks 250. Auxiliary blocks 270 are hinged inside the two hinge seats 260. Connecting rods 280 are provided at the ends of several auxiliary blocks 270. Connecting seats 290 are hinged in the middle of the connecting rods 280. The end of the connecting seat 290 is fixedly connected to the protective box 230. The end of the connecting rod 280 is provided with a plug 2910. A lead screw 2920 is rotatably connected to one side of the inner wall of the protective box 230. The outer wall of the lead screw 2920 is threadedly connected to the moving block 250. A rotating head is provided on one side of the lead screw 2920, which passes through the protective box 230 and the fixing plate 220. Two damping rod springs 2930 are provided at the bottom of one of the connecting slots. A limit head 2940 is provided at the bottom of the two damping rod springs 2930. A slot is opened at the bottom of the limit head 2940. The slot is inserted and connected to the plug 2910. The top of the other connecting slot is provided with the same structure. A limit groove is opened in the middle of the two connecting rods 210.
[0027] In one specific embodiment, the fixed plate 220 allows the user to easily insert the connecting rod 210 and the protective box 230 into the M-shaped groove by holding the fixed plate 220. When the connecting rod 210 enters the M-shaped groove, it will first contact the limiting head 2940. The limiting head 2940, under pressure, transmits force to the damping rod spring 2930. The damping rod spring 2930, under pressure, will contract, allowing the connecting rod 210 to continue moving. When the connecting rod 210 is fully inserted into the M-shaped groove, the limiting groove will contact the limiting head 2940. At this point, the limiting... The head 2940 will be engaged in the limiting groove on the connecting rod 210 to achieve initial fixation. At this time, the user will rotate the head to drive the lead screw 2920 to rotate. The rotation of the lead screw 2920 will cooperate with the limiting rod 240 through the external thread, thereby causing the moving block 250 to move. The moving block 250 will cause the connecting rod 280 to move through the connecting seat 290 through the hinge seat 260 and the auxiliary block 270, thereby driving the plug 2910 to be inserted into the slot in the limiting head 2940 and fixed, thereby achieving the purpose of quick connection and stability.
[0028] Please refer to Figure 4. Several limit heads 2940 are all cast from metallic chromium.
[0029] In one specific embodiment, the presence of chromium metal allows the limiting head 2940 to withstand greater pressure and wear by utilizing its high hardness and strength, thus extending its service life.
[0030] Please refer to Figure 4. Several plugs 2910 are made of tungsten metal.
[0031] In one specific embodiment, the presence of tungsten metal allows the plug 2910 to provide stable mechanical strength during connection by utilizing the extremely high density and hardness of tungsten.
[0032] Please refer to Figure 1-4. Several anti-slip textures are provided on the outside of the swivel ring.
[0033] In one specific embodiment, the anti-slip texture increases the friction between the hand and the rotating ring during use, preventing slippage during rotation or operation and improving operational safety and stability.
[0034] Please refer to Figure 1-4. Both fixing plates 220 are cast from titanium alloy.
[0035] In one specific embodiment, the titanium alloy provided facilitates the use of the fixing plate 220, taking advantage of the excellent corrosion resistance and fatigue resistance of the titanium alloy, making it suitable for applications that withstand long-term dynamic loads and harsh environments.
[0036] Please refer to Figure 3-4. The outer walls of several limit heads 2940 and plugs 2910 are coated with wear-resistant paint.
[0037] In one specific embodiment, the wear-resistant coating makes the limit head 2940 and plug 2910 more wear-resistant when used, thereby improving their service life.
[0038] In use, the connecting rod 210 and the protective box 230 are first inserted into the M-shaped groove by the user holding the fixed plate 220. When the connecting rod 210 enters the M-shaped groove, it will first contact the limiting head 2940. The limiting head 2940 transmits force to the damping rod spring 2930, which will contract, allowing the connecting rod 210 to continue moving. Then, when the connecting rod 210 is fully inserted into the M-shaped groove, the limiting groove will contact the limiting head 2940. At this time, the limiting head... 2940 will be initially fixed by engaging the limiting groove on the connecting rod 210. Then, the user will rotate the head to drive the lead screw 2920 to rotate. The rotation of the lead screw 2920 will engage with the limiting rod 240 through the external thread, thereby moving the moving block 250. Finally, the moving block 250 will move the connecting rod 280 through the connecting seat 290 via the hinge seat 260 and the auxiliary block 270, thereby driving the plug 2910 to be inserted into the slot in the limiting head 2940 and fixed, thus achieving the purpose of quick connection and stability.
