[0025] The technical solutions of this patent will be further described in detail below in conjunction with specific embodiments
[0026] As Figures 1-3 shown, the present utility model provides a technical solution: an ancient building rafter fixing connector, including a backbone 1, a rafter rod 2 is arranged on one side of the backbone 1, a fixing device 3 is arranged between the backbone 1 and the rafter rod 2, the fixing device 3 includes a bottom plate 31, a connecting device 4 is arranged between the bottom plate 31 and the backbone 1, a round hole seat 32 is fixedly connected to one side of the bottom plate 31, a rectangular cylinder 33 is fixedly connected to one side of the round hole seat 32, the inner wall of the rectangular cylinder 33 is connected to the inner wall of the round hole seat 32, a threaded hole 34 is opened on one side of the rectangular cylinder 33, a screw 37 is threadedly connected to the inner wall of the threaded hole 34, one end of the screw 37 is rotatably connected to a pressing plate 38, the surface of the pressing plate 38 is slidably connected to the inner wall of the rectangular cylinder 33. By setting the fixing device 3, first, the bottom plate 31 is fixedly connected to the backbone 1 through the connecting device 4. At this time, manually move the rafter rod 2. When the rafter rod 2 moves to the position where it is inserted into the round hole seat 32, manually rotate the screw 37, so that the screw 37 moves up and down along the inside of the threaded hole 34, so that the screw 37 drives the pressing plate 38 to move up and down along the inside of the rectangular cylinder 33. When the pressing plate 38 moves to the position where it presses the surface of the rafter rod 2 inside the round hole seat 32, the pressing plate 38 fixes the rafter rod 2 inside the round hole seat 32 by pressing the rafter rod 2, thereby completing the rapid assembly between the rafter rod 2 and the backbone 1. At the same time, the rafter rod can be quickly disassembled in the later stage, reducing the damage to the surface of the rafter rod 2 caused by personnel during the installation of the rafter rod 2, resulting in a reduction in the load-bearing performance of the rafter rod 2, and improving the convenience and efficiency of personnel in installing the rafter rod 2
[0027] Specifically, as Figure 2 and Figure 3As shown, one end of the screw rod 37 away from the pressing plate 38 is fixedly connected with a screwing block 310. Multiple grooves are formed on the surface of the screwing block 310. By setting the screwing block 310, the contact area of the screw rod 37 can be increased, enabling personnel to drive the screw rod 37 to rotate quickly by manually rotating the screwing block 310, thus improving the convenience of manually rotating the screw rod 37. One side of the pressing plate 38 is fixedly connected with a plurality of anti-slip strips 39, and the plurality of anti-slip strips 39 are arranged at equal distances. By setting the anti-slip strips 39, the friction between the pressing plate 38 and the rafter rod 2 can be increased, reducing the situation of sliding when the pressing plate 38 presses the surface of the rafter rod 2, and further improving the fixing efficiency of the pressing plate 38 on the rafter rod 2.
[0028] Specifically, as Figure 2 and Figure 3 shown, one side of the pressing plate 38 is fixedly connected with a positioning rod 311. A circular hole 35 is formed on one side of the rectangular cylinder 33. The surface of the positioning rod 311 is slidably connected with the inner wall of the circular hole 35. By setting the positioning rod 311, the positioning rod 311 can be located inside the circular hole 35 to assist in limiting the pressing plate 38, reducing the situation of shaking of the pressing plate 38 during use, and improving the stability of the pressing plate 38. One side of the round hole seat 32 is fixedly connected with a reinforcing block 36, and the reinforcing block 36 is fixedly connected with the bottom plate 31. By setting the reinforcing block 36, the connection between the round hole seat 32 and the bottom plate 31 can be strengthened, improving the connection strength between the round hole seat 32 and the bottom plate 31, and reducing the situation of separation between the two.
[0029] Specifically, as Figure 3 and Figure 4As shown in the figure, the connecting device 4 includes a threaded hole block 41. The threaded hole block 41 is fixedly connected to the backbone 1. A bolt 42 is threadedly connected to the inner wall of the threaded hole block 41. One side of the bottom plate 31 is fixedly connected to a rectangular frame 44. The rectangular frame 44 penetrates the bottom plate 31. The inner wall of the rectangular frame 44 is slidably inserted into the surface of the threaded hole block 41. The size and shape of the surface of the bolt 42 are adapted to the size and shape of the inner wall of the rectangular frame 44. By setting the connecting device 4, first manually move the bottom plate 31, so that the bottom plate 31 drives the rectangular frame 44 to move. When the bottom plate 31 moves to the position where it fits against the surface of the backbone 1, the rectangular frame 44 is sleeved on the surface of the threaded hole block 41, so that the inner wall of the threaded hole block 41 coincides with the inner wall of the hole of the rectangular frame 44. At this time, use a tool to rotate the bolt 42, so that the bolt 42 is screwed into the hole of the rectangular frame 44 and the inside of the threaded hole block 41 to fix the positions of the rectangular frame 44 and the bottom plate 31, thereby completing the rapid assembly between the fixing device 3 and the backbone 1. At the same time, the fixing device 3 can be quickly disassembled in the later stage, improving the flexibility of use of the fixing device 3 and the convenience of later maintenance. A limiting block 45 is fixedly connected to the inner wall of the rectangular frame 44. A limiting groove 43 is opened on one side of the threaded hole block 41. The size and shape of the surface of the limiting block 45 are adapted to the size and shape of the inner wall of the limiting groove 43. By setting the limiting block 45 and the limiting groove 43, the limiting block 45 can be inserted into the limiting groove 43 to assist in limiting the rectangular frame 44, reducing the situation of left and right shaking of the rectangular frame 44.
[0030] The working principle of the present utility model is as follows:
[0031] S1. First, manually move the bottom plate 31, so that the bottom plate 31 drives the rectangular frame 44 to move. When the bottom plate 31 moves to the position where it fits against the surface of the backbone 1, the rectangular frame 44 is sleeved on the surface of the threaded hole block 41, so that the inner wall of the threaded hole block 41 coincides with the inner wall of the hole of the rectangular frame 44. At this time, use a tool to rotate the bolt 42, so that the bolt 42 is screwed into the hole of the rectangular frame 44 and the inside of the threaded hole block 41 to fix the positions of the rectangular frame 44 and the bottom plate 31, thereby completing the rapid assembly between the fixing device 3 and the backbone 1.
[0032] S2. At this time, manually move the rafter rod 2. When the rafter rod 2 moves to the position where it is inserted into the round hole seat 32, manually rotate the screwing block 310, so that the screwing block 310 drives the screw rod 37 to rotate, so that the screw rod 37 moves up and down along the inside of the threaded hole 34, so that the screw rod 37 drives the pressing plate 38 to move up and down along the inside of the rectangular cylinder 33. When the pressing plate 38 moves to the position where it presses the surface of the rafter rod 2 inside the round hole seat 32, the pressing plate 38 fixes the rafter rod 2 inside the round hole seat 32 by pressing the rafter rod 2, thereby completing the rapid fixing and assembly between the rafter rod 2 and the backbone 1.
