The frame 5 needs to be fastened with bolts at different positions and angles. The rotating device is used for rotating the frame 5. The rotating shaft 21 is rotationally connected to the upper end of the support column 1. The rotating shaft 21 can rotate 360° around the support column 1 and rotate the clamping device 4, so as to rotate the frame 5 clamped in the clamping device 4. When the frame 5 is rotated to a suitable angle, the limiting piece 12 on the support column 1 is clamped with the limiting disc 22, so that the frame 5 clamped in the clamping device 4 is kept at the angle, so that the user can carry out training.

[0038] Referring to Figure 1 , Figure 2 , the clamping device 4 comprises a fixed rod 41, the middle part of the fixed rod 41 is fixedly connected with the second end of the rotating shaft 21; a clamping plate 42, at least two clamping plates 42 are oppositely arranged at the two ends of the fixed rod 41, and a threaded hole is arranged on the clamping plate 42; and a fastener 43 is screwed in the threaded hole.

[0039] The clamping device 4 can clamp frames 5 of different thicknesses by rotating the fastener 43. Different types of frames can be adapted, and by replacing different training frames, the training personnel can quickly and skillfully assemble various frames and corresponding bolts.

[0040] Referring to Figure 1 , Figure 2 , the support column 1 is provided with a mounting hole 11 penetrating through the left and right of the support column 1, and the rotating shaft 21 is rotationally connected with the support column 1 through the mounting hole 11, so that the rotation of the rotating shaft 21 is more stable.

[0041] Referring to Figure 1 , Figure 2As shown, it also includes a ball bearing 13, which is disposed between the mounting hole 11 and the rotating shaft 21. Since the ball bearing 13 needs to bear large radial and axial forces, a 6220 thickened deep groove ball bearing is selected and installed in the mounting hole 11 with an interference fit. A retaining ring 14 specifically for the 6220 thickened deep groove ball bearing is installed on the outside of the 6220 thickened deep groove ball bearing 13, thereby fixing the inner and outer rings of the ball bearing 13.

[0042] See Figure 1 , Figure 2 As shown, the support column 1 includes: a first connecting column, with mounting holes 11 located at the upper end of the first connecting column, and the first connecting column having several positioning holes of different heights; a second connecting column, which is slidably fitted onto the lower end of the first connecting column, and the second connecting column having positioning holes 2 penetrating the outer wall of the second connecting column; positioning holes 1 and positioning holes 2 are connected by positioning pins.

[0043] By aligning the positioning hole one and positioning hole two at the appropriate height and then fixing them with positioning pins, the height of the training platform can be changed according to factors such as the user's height and the height of the frame 5. In this embodiment, the height of the support column 1 can be increased by 200mm.

[0044] See Figure 1 , Figure 2 As shown, the rotating device 2 also includes a rotating handle 23, which is fixedly installed on the rotating shaft 21. The rotating shaft 21 is sequentially provided with the rotating handle 23, the limiting plate 22, the support column 1, and the clamping device 4.

[0045] Using the rotary handle 23 to control the rotating shaft 21 makes it easier for the user to change the rotation angle of the rotating device 2. The rotary handle 23 is located on the outside of the limit plate 22, making it easy to operate.

[0046] See Figure 1 , Figure 2 As shown, it also includes a base plate 15, and the support column 1 is installed on the base plate 15 to improve the stability of the overall structure.

[0047] See Figure 1 , Figure 2 As shown, there are two rotating devices 2, which are respectively installed on two support columns 1 and two clamping devices 4 are arranged opposite to each other, respectively clamping the two ends of the frame 5.

[0048] When clamping some longer frames 5, two clamping devices 4 are needed to clamp both ends of the frame simultaneously to prevent the frame 5 from falling off when only one end is clamped, thus injuring the user and improving the safety of the training platform.

[0049] See Figure 1 , Figure 2As shown, the limiting disc 22 is provided with a plurality of limiting grooves in the circumferential direction, and the limiting grooves are clamped with the limiting member 12. In this embodiment, the limiting grooves are four, and are evenly distributed on the limiting disc 21. The four limiting grooves enable the entire limiting disc 22 to rotate by 0°, 90°, 180° and 270°. After rotating to the appropriate angle, the clamping device 4 can be fixed at the angle by clamping the limiting member 12 into the limiting groove.

[0050] As shown in Figure 1 , Figure 2 As shown, the bolt storage box 3 is installed on the side of the support column 1. The bolt storage box 3 is made of 2mm stainless steel plate by welding, and the edges are rounded to avoid scratching. Considering that the bolt storage box 3 may interfere with the height adjustment of the support column 1, and at the same time, the mobility of the bolt storage box is strengthened, a neodymium iron boron strong magnet is arranged in the bolt storage box 3 to fix the bolt storage box 3 to the side of the support column 1.

[0051] Further, anti-skid paint is applied to the contact surface of the fastener 43 and the frame 5 to improve the clamping effect.

[0052] Further, the bottom plate 15 is provided with universal wheels 16 at the bottom, which facilitates the user to move the training platform to the desired position.

[0053] Further, the training platform further includes pneumatic, oil pressure, electric and manual bolt tightening tools.

[0054] Further, the support column 1 is a square steel pipe with a height of 30mm.

[0055] Further, the limiting member 12 is arranged in the through hole of the mounting table at the top of the support column 1, and the top of the limiting member is provided with a fixing block with a diameter larger than the inner diameter of the through hole, and the diameter of the limiting member is smaller than the inner diameter of the through hole, so that the limiting member 12 can be taken out from above the mounting table by the user, so as to be separated from the limiting groove.

[0056] The use process of the frame bolt fastening training platform of this embodiment is as follows:

[0057] When using the training platform, the user needs to adjust the relative position of the first connecting column and the second connecting column, and fix the positioning hole one and the positioning hole two by using the positioning pin, so as to adjust the entire training platform to the appropriate height; the two ends of the training frame 5 are placed between the clamping devices 4 on both sides, and the fasteners 43 of the clamping devices 4 are screwed into the frame, so as to fix the frame 5; during the training process, the angle of the frame 5 is changed by rotating the limiting disc 22 and clamping the limiting member 12 with the limiting disc 22, so as to facilitate the user to master the technology of fastening the bolts on the frame at each angle.

[0058] After the training is completed, the frame 5 is removed to avoid that the training platform bears too large load for a long time.

[0059] The above examples are only used to illustrate the technical solutions of the present application, and are not intended to limit the present application; although the present application has been described in detail with reference to the foregoing examples, those skilled in the art should understand that the technical solutions recorded in the foregoing examples can be modified, or some technical features can be replaced by equivalent features; and these modifications or replacements do 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 application.
