[0002] Aluminum alloy formwork is a building mold used in construction, which has the characteristics of being detachable and reusable.

[0003] Chinese Patent CN217581195U discloses an aluminum alloy formwork for the external corner of a wall, including an external corner formwork fixedly connected by a back rib, a tie rod, and an L-shaped connecting plate. The ends of the back ribs on the outer side of the external corner formwork are fixedly connected to a connecting member. The connecting member includes a first mounting plate and a second mounting plate enclosing a right angle. Plugging rods are fixed on the first mounting plate and the second mounting plate. Plugging holes adapted to the plugging rods are provided at the ends of the back ribs.

Detailed implementation manners

[0028] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art without creative efforts based on the embodiments of the present invention belong to the scope of protection of the present invention.

[0029] The "left", "right", "front", "rear", "upper", and "lower" mentioned in the following description are oriented in the perspective direction of the front view.

[0030] Please refer to the accompanying drawings of the specification Figures 1-5, a yangjiao connection structure, comprising a connecting rod 1, an angle adjusting mechanism 2, a plug-in block 3 and a loading and unloading mechanism 4.

[0031] One end of each of the two connecting rods 1 is rotatably connected to each other.

[0032] The angle adjusting mechanism 2 is installed at the rotational connection of the two connecting rods 1 for adjusting the included angle between the two connecting rods 1.

[0033] Specifically, the angle adjusting mechanism 2 includes a first inner chuck 21, a second inner chuck 22, a first outer chuck 23, a second outer chuck 24 and a bolt 25. A bolt 25 is fixed at the central position of the first outer chuck 23. The first inner chuck 21, the second inner chuck 22 and the second outer chuck 24 are respectively rotatably passed through the bolt 25 at the center, and a nut is screwed at the outer end of the bolt 25. The first inner chuck 21 and the second inner chuck 22 are located between the first outer chuck 23 and the second outer chuck 24 and are respectively fixedly connected to the rotational connection ends of the two connecting rods 1. A plurality of teeth are circumferentially and evenly distributed on the sides of the first inner chuck 21 and the second inner chuck 22 away from each other and on the sides of the first outer chuck 23 and the second outer chuck 24 close to each other.

[0034] Before installation, detect the angle of the wall corner, then loosen the nut of the bolt 25, rotate the first inner chuck 21 and the second inner chuck 22 to a suitable angle, and then rotate the nut to fix and lock it, so as to realize the adjustment of the angle size and not affect the installation and disassembly speed of the connecting rod 1 and the plug-in block 3.

[0035] One plug-in block 3 is installed on each aluminum alloy template.

[0036] The loading and unloading mechanism 4 includes a gear 42, a plug-in slot 43, a rack 44 and a positioning component 45. One gear 42 is rotatably connected to the other end of each connecting rod 1. The plug-in slot 43 is opened at one end of the plug-in block 3 for the connecting rod 1 to insert. The rack 44 is arranged on the inner wall of the plug-in slot 43. When the connecting rod 1 is inserted into the plug-in slot 43, the gear 42 can be meshed with the rack 44, and the positioning component 45 can keep the gear 42 rotating or locked.

[0037] Specifically, one positioning component 45 is arranged on each connecting rod 1, which includes a ratchet 451, a pawl block 452, a spring 453 and a slide rail 454. The ratchet 451 is rotatably connected to the other end of the connecting rod 1 and is coaxially and fixedly connected to the gear 42. The slide rail 454 is arranged on one side of the connecting rod 1. The pawl block 452 is provided with a pawl. The pawl block 452 is slidably connected to the slide rail 454 and is connected to the side wall of the connecting rod 1 through the spring 453. The spring 453 can provide an elastic force to make the pawl of the pawl block 452 abut against the tooth groove of the ratchet 451.

[0038] Move the connecting rod 1 so that the gear 42 rolls on the rack 44 and enters the insertion slot 43. The gear 42 drives the ratchet wheel 451 to rotate. The ratchet wheel 451 pushes the pawl block 452 to contract. When the gear 42 moves to the innermost end of the insertion slot 43, the ratchet wheel 451 stops rotating, and the installation is completed at this time. If the connecting rod 1 has a tendency to move out of the insertion block 3, the gear 42 will have a tendency to rotate counterclockwise, and the ratchet wheel 451 will rotate counterclockwise. However, blocked by the pawl block 452, the ratchet wheel 451 cannot rotate, thus realizing the fixing operation. When disassembling, just toggle the pawl block 452 to directly pull out the gear 42 to realize disassembly, which is convenient and fast.

[0039] Preferably, a locking component 5 is further included, and one is provided on each connecting rod 1. The locking component 5 includes a clamping groove 51, a U-shaped insertion block 52, and a slot 53. The slot 53 is opened on the side wall of the connecting rod 1 and is located on the moving path of the pawl block 452. The clamping groove 51 is opened on one side of the pawl block 452. When the pawl of the pawl block 452 abuts into the tooth groove of the ratchet wheel 451, both ends of the U-shaped insertion block 52 will be able to insert into the slot 53 and its concave surface will insert into the clamping groove 51.

[0040] Insert both ends of the U-shaped insertion block 52 into the slot 53, and make the concave surface of the U-shaped insertion block 52 clamp the clamping groove 51 on the pawl block 452, thereby locking the position of the pawl block 452, preventing the pawl block 452 from loosening and moving under vibration and other conditions, resulting in the disconnection of the connecting rod 1 and the insertion block 3, and increasing the connection stability and safety.

[0041] Furthermore, a limiting component 41 is further included, which includes a limiting groove 411 and a limiting block 412. The limiting groove 411 is opened on the inner wall of the insertion slot 43, and the limiting block 412 is provided on the side wall of the connecting rod 1. When the connecting rod 1 is inserted into the insertion slot 43, the limiting block 412 will correspondingly insert into the limiting groove 411.

[0042] When the utility model is in use, the included angle between the two connecting rods 1 is adjusted through the angle adjusting mechanism 2, so that the two connecting rods 1 can adapt to the wall corners with different angle sizes to realize the assembly operation; align the two connecting rods 1 with the insertion block 3 through the limiting component 41, and then directly push the two connecting rods 1 into the insertion block 3. The gear 42 enters the insertion slot 43 along the track of the rack 44. The locking component 5 locks the positioning component 45. The gear 42 moves to the innermost side of the insertion slot 43, and the positioning component 45 is used to clamp the gear 42 to avoid retraction to realize quick fixation.

[0043] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
