Description

Technical Field

[0001] This utility model belongs to the technical field of locking devices, and in particular relates to a quick locking device for steel structure connections. Background Technology

[0002] According to the published patent CN219240893U, a locking device for a steel structure connector includes a horizontal profile and a vertical profile. Both ends of the horizontal and vertical profiles have mounting grooves, and the outer walls of the horizontal and vertical profiles have through grooves. A locking element is movably installed inside the mounting groove. Specifically, the locking element includes two integrally formed locking blocks, which facilitates rapid assembly of the two profiles and simplifies the installation steps between the profiles. However, it still has the following shortcomings:

[0003] The above-mentioned equipment can connect and assemble steel materials during use. However, due to its simple structure, the steel materials are prone to loosening after being fixed for a long time, which may lead to the failure of the steel connection and reduce the stability of the device. Therefore, we propose a quick locking device for steel structure connection. Utility Model Content

[0004] The purpose of this utility model is to provide a quick locking device for steel structure connection. Through the connection mechanism and the reinforcement mechanism, it solves the problem that when the above-mentioned equipment is used, it can connect and assemble steel materials, but due to its simple structure, the steel materials are prone to loosening after long-term fixation, which may lead to the failure of steel material connection and reduce the stability of the device.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a quick locking device for steel structure connection, including several I-beams, with connecting blocks inserted into the outer wall of the I-beams, and a connecting mechanism provided on the outer wall of the I-beams;

[0007] The connecting mechanism includes several slide rails. Several threaded rods are rotatably connected to the outer wall of the connecting block near one end of the slide rail. Rotating blocks are threaded to the outer walls of the threaded rods. Several fixed shafts are rotatably connected to the inner wall of the rotating blocks. Connecting rods are fixedly connected to the outer walls of the fixed shafts. Fixed shaft II is fixedly connected to the inner wall of the connecting rod away from the fixed shaft. A locking block is rotatably connected to the outer wall of the fixed shaft II. Several I-beam slots are provided on the inner walls of the connecting blocks near the locking blocks. A reinforcing mechanism is provided on the outer wall of the connecting block.

[0008] Furthermore, the outer walls of several of the slide rails are fixedly connected to the outer wall of the connecting block, and the outer wall of the locking block is slidably connected to the inner wall of the slide rail.

[0009] Furthermore, the inner wall of the slot located in the middle is slidably connected to the outer wall of the block, and the slot is L-shaped and symmetrically distributed with the threaded rod as the center.

[0010] Furthermore, the reinforcement mechanism includes several rotating shafts, and the outer walls of the several rotating shafts are rotatably connected to the outer wall of the connecting block.

[0011] Furthermore, gears are fixedly connected to the outer walls of several of the rotating shafts, and a worm gear is fixedly connected to the outer wall of the end of the rotating shaft away from the gear.

[0012] Furthermore, a number of fixing blocks are fixedly connected to the outer wall of the connecting block near the worm wheel, and a worm is rotatably connected to the inner wall of the fixing block, with the outer wall of the worm meshing with the outer wall of the worm wheel.

[0013] Furthermore, a number of limiting plates are fixedly connected to the outer wall of the connecting block near the worm gear, and a rack is slidably connected to the outer wall of each of the limiting plates, with the outer wall of the rack meshing with the outer wall of the gear.

[0014] Furthermore, a number of insert rods are fixedly connected to the outer wall of the rack near the I-beam, and a number of positioning holes are opened on the inner wall of the connecting block near the insert rods. The outer wall of the insert rods is inserted into the inner wall of the positioning holes, and the insert rods pass through the locking block to the inner wall of the positioning holes.

[0015] This utility model has the following beneficial effects:

[0016] 1. This utility model features a connecting rod on a fixed shaft. When the equipment is needed, rotating the threaded rod causes the rotating block to move away from the connecting block. This movement of the rotating block causes multiple fixed shafts to move, pulling the connecting rod. The connecting rod then pulls the fixed shaft, causing the locking block to slide within the slide rail towards the threaded rod, completely disengaging it from the slot. At this point, the I-beam can be pulled out from both sides of the connecting block, facilitating easy connection and fixation for the I-beam. The device's fixing method is simple and convenient, requiring no additional tools for easy connection and user-friendly operation.

[0017] 2. This utility model incorporates a gear on the rotating shaft. During operation, the worm gear is rotated first, which in turn drives the worm wheel to rotate, causing the rotating shaft to rotate. This rotation, in turn, drives the gear to rotate, causing multiple racks to slide simultaneously within the limiting plate towards the rotating shaft. As the racks move, they pull multiple insert rods out of the positioning holes. Once the insert rods are completely removed from the locking block, the threaded rod is rotated. This reinforces the connection after the I-beam is connected and fixed, improving the stability of the device and preventing loosening due to external forces, which could lead to connection failure.

[0018] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1-5As shown, this utility model is a quick locking device for steel structure connection, including several I-beams 1, with connecting blocks 101 inserted into the outer wall of the I-beams 1, and a connecting mechanism 2 provided on the outer wall of the I-beams 1. Through the connecting blocks 101, when the user inserts multiple I-beams 1 into the connecting blocks 101, the multiple I-beams 1 can be connected to each other.

[0029] The connecting mechanism 2 includes several slide rails 201. Several threaded rods 202 are rotatably connected to the outer wall of the connecting block 101 near one end of the slide rail 201. Rotating blocks 203 are threadedly connected to the outer walls of each threaded rod 202. Several fixed shafts 204 are rotatably connected to the inner walls of the rotating blocks 203. The fixed shafts 204 can limit the position of the connecting rod 205, ensuring it can only rotate on the fixed shafts 204, and preventing the connecting rod 205 from falling off. Connecting rods 205 are fixedly connected to the outer walls of each fixed shaft 204. The inner wall of the connecting rod 205 at the end furthest from the fixed shaft 204... A fixed shaft 206 is fixedly connected, and a locking block 207 is rotatably connected to the outer wall of the fixed shaft 206. When the user fully passes the locking block 207 through the I-beam 1 and the connecting block 101, the I-beam 1 can be installed and fixed in the connecting block 101. Several connecting blocks 101 have several slots 208 on the inner wall of the end near the locking block 207. The outer wall of the connecting block 101 is provided with a reinforcing mechanism 3. The slots 208 can limit the position of the locking block 207. At the same time, when the locking block 207 is locked in the slot 208, the I-beam 1 can be fixed in the connecting block 101.

[0030] The outer walls of several slide rails 201 are fixedly connected to the outer wall of the connecting block 101. The outer wall of the locking block 207 is slidably connected to the inner wall of the slide rail 201. The inner wall of the locking groove 208 in the middle is slidably connected to the outer wall of the locking block 207. The locking groove 208 is L-shaped and symmetrically distributed with the threaded rod 202 as the center. The reinforcing mechanism 3 includes several rotating shafts 301. The rotating shafts 301 can limit the position of the gear 302 and the worm gear 303 to prevent the gear 302 from disengaging from the meshing state with the rack 307. The outer walls of several rotating shafts 301 are rotatably connected to the outer wall of the connecting block 101. The gear 302 is fixedly connected to the outer wall of several rotating shafts 301. The worm gear 303 is fixedly connected to the outer wall of the rotating shaft 301 away from the gear 302. Since the worm gear 303 and the worm 305 mesh with each other, when the user rotates the worm 305, the worm gear 303 can be driven to rotate, causing the rotating shaft 301 to rotate.

[0031] Several fixing blocks 304 are fixedly connected to the outer wall of the connecting block 101 near the worm gear 303. A worm 305 is rotatably connected to the inner wall of each fixing block 304. The outer wall of the worm 305 meshes with the outer wall of the worm gear 303. Several limiting plates 306 are fixedly connected to the outer wall of the connecting block 101 near the worm gear 303. The limiting plates 306 can restrict the movement trajectory of the rack 307, allowing it to move linearly along the direction of the limiting plates 306. The outer walls of the limiting plates 306 are slidably connected to the rack 307. The outer wall of the rack 307 interacts with the gear 302. The outer wall engages, and several insert rods 308 are fixedly connected to the outer wall of the rack 307 near the end of the I-beam 1. Several positioning holes 309 are opened on the inner wall of the connecting block 101 near the end of the insert rods 308. The outer wall of the insert rods 308 is inserted into the inner wall of the positioning holes 309. The insert rods 308 pass through the locking block 207 to the inner wall of the positioning holes 309. Through the positioning holes 309, when the user completely passes the insert rods 308 through the locking block 207 and inserts them into the positioning holes 309, the position of the locking block 207 can be fixed, preventing the locking block 207 from shifting and causing the I-beam 1 to fall out of the connecting block 101.

[0032] One specific application of this embodiment is:

[0033] When workers need to use this equipment, if multiple I-beams 1 need to be connected together, first insert multiple I-beams 1 into the connecting block 101 simultaneously. Then, by rotating the threaded rod 202, the locking block 207 is engaged in the slot 208 within the I-beam 1, thus completing the connection between the multiple I-beams 1. By inserting the insertion rod 308 through the locking block 207 into the positioning hole 309, the locking block 207 can be fixed, preventing it from loosening and causing the I-beams 1 to slide out of the connecting block 101 on their own. When it is necessary to separate the connecting block 101, first rotate the worm gear 305. The rotation of the worm gear 305 drives the worm wheel 303 to rotate, causing the rotating shaft 301 to rotate. The rotation of the rotating shaft 301 drives the gear 302 to rotate, causing multiple racks 307 to rotate. Simultaneously, the rack 307 slides towards the rotating shaft 301 within the limiting plate 306. When the rack 307 moves, it will drive multiple insert rods 308 to be pulled out from the positioning hole 309. After the insert rods 308 are completely pulled out from the locking block 207, the threaded rod 202 is rotated. The rotation of the threaded rod 202 can drive the rotating block 203 to move away from the connecting block 101. The movement of the rotating block 203 will drive multiple fixed shafts 204 to move, causing them to pull the connecting rod 205 to move. The movement of the connecting rod 205 will pull the fixed shaft 206, causing the locking block 207 to slide towards the threaded rod 202 within the slide rail 201, so that the locking block 207 is completely disengaged from the slot 208. At this time, the I-beam 1 can be pulled out from both sides of the connecting block 101 and removed.
