[0001] This utility model relates to the technical field of keel installation tools, and in particular to a quick splicing device for double-sided three-layer light steel M keel. Background Technology

[0002] The double-sided three-layer light steel M-keel quick splicing device is a connecting component used in the construction of prefabricated building walls. It is suitable for the rapid assembly of light steel structure buildings such as residential buildings and office buildings. The existing double-sided three-layer light steel M-keel quick splicing device generally uses bidirectional screw rods to control the clamps on both sides of the keel to clamp the keel, thereby quickly splicing two keels. However, since the length of the splicing device is fixed, when it is necessary to adjust the keel spacing, it can only be disassembled and reassembled, which makes the adjustment relatively troublesome. Therefore, the above-mentioned problems need to be improved. Utility Model Content

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Example: See Figures 1 to 5 This utility model discloses a quick-assembly device for double-sided three-layer light steel M-type keel, comprising a first splicing plate 1, a second splicing plate 2 installed at the rear end of the first splicing plate 1, and the rear end face of the first splicing plate 1 abutting against the front end face of the second splicing plate 2; a fixing mechanism is installed in the middle of the second splicing plate 2, and a limiting mechanism is installed at both ends of the first splicing plate 1 and the second splicing plate 2, allowing for quick installation of the keel through the fixing mechanism and the limiting mechanism; the fixing mechanism includes two hexagon socket head cap screws 5 longitudinally rotatably connected to both sides of the second splicing plate 2, and a sliding plate is threaded to the front end of each hexagon socket head cap screw 5. 4. A sliding groove is provided in the middle of the first splicing plate 1 to slide with the hexagon socket bolt 5. A movable groove is provided at the front end of the inner wall of the sliding groove. The sliding plate 4 is placed in the movable groove and slides. The sliding plate 4 can be used to fix the first splicing plate 1 and the second splicing plate 2 by cooperating with the hexagon socket bolt 5. Sliding grooves are provided on one rear end of the first splicing plate 1 and the other front end of the second splicing plate 2. Mounting boxes are installed on one front end of the first splicing plate 1 and the other rear end of the second splicing plate 2. A guide rod is fixed in the sliding groove longitudinally. The sliding direction of the limiting plate 3 can be controlled by the guide rod.

[0020] In this utility model, the limiting mechanism includes limiting plates 3 installed on both sides of the first splicing plate 1 and the second splicing plate 2. The limiting plates 3 are slidably connected to two guide rods, and the adjacent sides of the limiting plates 3 are respectively placed in two sliding grooves for sliding. Screws 6 are installed on the distal sides of the limiting plates 3, and the limiting plates 3 are threadedly connected to the screws 6. The two screws 6 are longitudinally rotatably connected to two mounting boxes, and the screws 6 facilitate control of the limiting plates 3 clamping the keel. Multiple connecting rods 7 are installed between the first splicing plate 1 and the limiting plates 3, and between the second splicing plate 2 and the limiting plates 3. The connecting rods 7 are placed in pairs at the upper and lower ends of the two sliding grooves, and the distal ends of the two pairs of connecting rods 7 are rotatably connected to the first splicing plate 1 and the limiting plates 3 and the second splicing plate 2, respectively. On the splicing plate 2 and the limiting plate 3, connecting plates 8 are installed on the adjacent sides of the connecting rods 7 on both sides. The other end of the connecting rods 7 is rotatably connected to the connecting plates 8. Multiple springs 10 are equidistantly connected on the adjacent sides of the connecting plates 8 on both sides. Abutment plates 9 are connected on the adjacent sides of the springs 10 on both sides. The abutment plates 9 are all sleeved on the connecting plates 8. The sliding plate 4 facilitates the fixing of the first splicing plate 1 and the second splicing plate 2 by cooperating with the internal hexagon bolts 5. Worm gears 11 are fixedly connected to the distal ends of the two screws 6. One side of the worm gear 11 meshes with a worm gear 12 for transmission. The upper and lower ends of the worm gear 12 are rotatably connected to the mounting box. The upper end of the worm gear 12 passes through the mounting box and has an internal hexagon groove. The worm gear 12 facilitates the control of the rotation of the screws 6 and achieves self-locking.

[0021] Working Principle: When using the double-sided three-layer light steel M-keel quick splicing device of this utility model, the first splicing plate 1 and the second splicing plate 2 need to be fixed by longitudinally rotating the hexagonal bolts 5 on both sides of the second splicing plate 2. Specifically, by tightening the hexagonal bolts 5, the sliding plate 4 with its front threaded connection slides and locks in the movable groove at the front end of the sliding groove in the middle of the first splicing plate 1, thereby achieving a stable connection between the first splicing plate 1 and the second splicing plate 2 and preventing loosening during use. Then, the two M-keels are placed between the first splicing plate 1 and the limiting plate 3 on both sides, and between the second splicing plate 2 and the limiting plate 3, respectively. The limiting plates 3 are slidably connected to the guide rods in the sliding grooves on both sides of the first splicing plate 1 and the second splicing plate 2. At this time, by rotating the worm gear 11 fixed to the distal end of the screw 6 in the mounting box, the worm gear 12 meshing with it can be driven to rotate, thereby controlling the rotation of the screw 6. The screw 6 connected to the worm gear 11 rotates. Since the limiting plate 3 is threadedly connected to the screw 6, the rotation of the screw 6 will cause the limiting plate 3 to slide along the guide rod to clamp the M keel. At the same time, the movement of the limiting plate 3 will drive the multiple connecting rods 7 between the first splicing plate 1 and the limiting plate 3, and between the second splicing plate 2 and the limiting plate 3 to move. This will cause the connecting plates 8 connected to the near sides of the connecting rods 7 on both sides to move inward. The abutment plates 9 connected to the near sides of the connecting plates 8 by multiple springs 10 will press against the M keel under the buffering effect of the springs 10 to prevent the keel from sliding laterally. If it is necessary to change the installation spacing between the keels during use, simply reverse the internal hex bolt 5 to loosen it. At this time, the first splicing plate 1 and the second splicing plate 2 can slide relative to each other along the slide groove to adjust the spacing. After the spacing is adjusted appropriately, turn the internal hex bolt 5 forward again to make the slide plate 4 clamp the movable groove again, thus fixing the keel spacing. This completes the splicing and installation of the entire keel.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
