Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0038] In this embodiment, as Figure 1 and Figure 2 As shown, a step-by-step beam clamping fixture includes: a bearing rod 1 with evenly distributed limit holes on the bearing rod 1; a fixed hook plate 2, which is used to distribute the stress points of the external crossbeam; the fixed hook plate 2 includes a right-angle elbow 21, a clamping seat 22, and two foot plates 23; one end of the right-angle elbow 21 is machined with a limit groove and is fixedly connected to the bearing rod 1; the clamping seat 22 is fixedly connected to the end of the right-angle elbow 21 away from the bearing rod 1; both foot plates 23 are hinged to the clamping seat 22 by pins; and a movable clamping plate 3, which works in conjunction with the foot plates 23 to clamp the external crossbeam.

[0039] Therefore, the right-angle elbow 21 is connected to the bearing rod 1 to fix the position of the two clamps 22. When the movable clamping plate 3 is used in conjunction with the foot plate 23 to clamp the external crossbeam, the foot plate 23 is rotated on the pin of the clamping plate 22, and the two foot plates 23 are separated by a certain angle. When the movable clamping plate 3 moves along the bearing rod 1 to clamp the external crossbeam, the foot plates 23 are separated by a certain angle to disperse the side stress of the crossbeam, improve the overall stress performance, and effectively suppress the deformation of the component caused by the expansion mold.

[0040] Specifically, the bearing rod 1 is used to connect the fixed hook plate 2 and the movable clamping plate 3. The right-angle elbow 21 is machined with a limiting groove that matches the bearing rod 1. There are two clamping seats 22. The clamping seats 22 are machined with raised edges to restrict the circumferential rotation of the foot plate 23. (The raised edges in the clamping seats 22 restrict the deflection angle of the foot plate 23, thereby controlling the included angle between the two foot plates 23.) The movable clamping plate 3 cooperates with the foot plate 23 to clamp the external crossbeam.

[0041] In some embodiments, such as Figure 3 As shown, the movable clamping plate 3 includes a fixing clamp 31, a support clamping plate 32, and a limiting member 33. The fixing clamp 31 and the bearing rod 1 are slidably connected. The fixing clamp 31 is equipped with a threaded pin 311. The fixing clamp 31 is connected to the limiting hole of the bearing rod 1 through the threaded pin 311. The support clamping plate 32 is connected to the fixing clamp 31 through a bearing. The limiting member 33 is located on the outer periphery of the fixing clamp 31. The limiting member 33 is used to constrain the deflection angle of the support clamping plate 32 so as to adjust the use position of the support clamping plate 32.

[0042] Specifically, the rectangular through groove in the fixing clamp 31 is adapted to the outer periphery of the bearing rod 1 and the connecting rod 41, the support clamp 32 rotates on the outer periphery of the fixing clamp 31 through the bearing, and the threaded pin 311 is used to constrain the position of the fixing clamp 31.

[0043] In some embodiments, such as Figure 3 As shown, the limiting component 33 includes a connecting pin 331, an arc-shaped sliding plate 332, and a nut 333. The connecting pin 331 is fixedly connected to the fixing clamp 31, the arc-shaped sliding plate 332 is inserted into the connecting pin 331, the arc-shaped sliding plate 332 is fixedly connected to the side wall of the support plate 32, the nut 333 is internally threaded to the connecting pin 331, and the nut 333 abuts against the outer arc surface of the arc-shaped sliding plate 332.

[0044] Specifically, the connecting pin 331 is threaded, and the arc-shaped slide plate 332 is machined with a groove that matches the connecting pin 331. The nut 333 is used to limit the position of the connecting pin 331 on the arc-shaped slide plate 332 in order to fix the offset angle of the support plate 32.

[0045] In some embodiments, such as Figure 4As shown, a clamping member 34 is provided in the support clamping plate 32. The clamping member 34 includes a transmission rod 341, a knob 342 and a fixing plate 343. The transmission rod 341 is internally threaded to the limiting hole of the support clamping plate 32. The fixing plate 343 is connected to the transmission rod 341 through a bearing. The fixing plate 343 is embedded in the storage groove of the support clamping plate 32. The knob 342 is fixedly connected to the end of the transmission rod 341 away from the fixing plate 343.

[0046] Specifically, the outer wall of the transmission rod 341 is threaded, the knob 342 is used to drive the transmission rod 341 to rotate, and the fixed plate 343 is machined into a disc shape. By adjusting the position of the fixed plate 343, it can clamp the recess of the outer crossbeam.

[0047] In some embodiments, such as Figure 4 As shown, the fixed disk 343 is machined with striped patterns to increase the surface roughness of the fixed disk 343.

[0048] The stripes on the fixed plate 343 are used to increase the friction between the fixed plate 343 and the external crossbeam, thereby improving the stability during connection.

[0049] In some embodiments, such as Figure 5 As shown, an expansion assembly 4 is installed at the end of the bearing rod 1 away from the right-angle bend 21. The expansion assembly 4 is used to extend the service length of the bearing rod 1. The expansion assembly 4 includes a connecting rod 41, a plug plate 42, and a bolt 43. The connecting rod 41 is adapted to the bearing rod 1. One end of the plug plate 42 is fixedly connected to the connecting rod 41, and the other end of the plug plate 42 is inserted into the slot of the bearing rod 1. The plug plate 42 is connected to the bearing rod 1 by the bolt 43. A groove is provided at the end of the connecting rod 41 away from the plug plate 42, and the groove is adapted to the plug plate 42.

[0050] Specifically, the extension rod 41 and the bearing rod 1 have the same shape and can be assembled together. The bearing rod 1 has a groove that matches the plug plate 42 at the end away from the right angle bend 21. There are two bolts 43. The bolts 43 are used to connect the plug plate 42 and the bearing rod 1 together. The groove of the extension rod 41 away from the plug plate 42 is used to connect multiple extension rods 41 end to end, extending the service length of the bearing rod 1.

[0051] In some embodiments, such as Figure 5 As shown, threaded holes 411 are evenly distributed at the top of the connecting rod 41, and the threaded holes 411 and the limiting holes of the bearing rod 1 are located on the same horizontal line.

[0052] The threaded hole 411 and the limiting hole of the bearing rod 1 are both adapted to the threaded pin 311. The threaded pin 311 can be inserted into the threaded hole 411 or the limiting hole of the bearing rod 1 to restrict the position of the fixing clamp 31.

[0053] In some embodiments, such as Figure 2 As shown, a reinforcing rib is provided at the corner of the right-angle elbow 21, which increases the load-bearing capacity of the right-angle elbow 21.

[0054] The reinforcing rib is triangular in shape. The use of the reinforcing rib prevents breakage at the bend of the right-angle bend 21.

[0055] The working principle of this application is illustrated below with a preferred embodiment:

[0056] Connect the limiting groove of the right-angle elbow 21 to the bearing rod 1, then place the entire mechanism on the outer wall of the crossbeam. Rotate the foot plate 23 in the bracket 22 so that the two foot plates 23 are separated at a certain angle and fit against the side wall of the crossbeam. Move the fixing clamp 31 on the outer wall of the bearing rod 1. The fixing clamp 31 drives the support clamp 32 to fit against the crossbeam. Use the threaded pin 311 to fix the position of the fixing clamp 31 on the bearing rod 1. According to the actual installation requirements, rotate the support clamp 32 on the outer wall of the fixing clamp 31. The support clamp 32 drives the arc-shaped sliding plate 332 to move on the outer wall of the connecting pin 331. Use the nut 333 to determine the position of the connecting pin 331 in the arc-shaped sliding plate 332 to fix the support. The offset angle of the support clamp 32 is adjusted, and then the knob 342 is rotated. The knob 342 drives the transmission rod 341 to move, and the transmission rod 341 drives the fixed plate 343 to re-clamp the crossbeam. The clamping point can be finely adjusted by changing the position of the fixed plate 343. When clamping a wider crossbeam, the end of the extension rod 41 with the plug plate 42 is inserted into the slot of the bearing rod 1. The plug plate 42 and the bearing rod 1 are connected with bolts 43 to extend the service length of the bearing rod 1. When connecting two extension rods 41, another plug plate 42 needs to be connected to the groove of the extension rod 41 and fixed with bolts 43 to achieve the end-to-end connection of multiple extension rods 41.
