DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present utility model are described clearly and completely below. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0024] like Figure 1-6 As shown, a fixed operating table made of an adjustable U-shaped support and hanger includes a workbench 1, a positioning member 2 and a sliding clamping fixing member 3; two positioning members 2 are provided, the two positioning members 2 are arranged opposite to each other, and are both fixedly connected to the workbench 1; the positioning member 2 has a right-angle positioning portion 4 to ensure that it is a right angle after welding.

[0025] The position of one of the positioning members 2 or both positioning members 2 is adjustable. Specifically, the position of one of the positioning members 2 is not adjustable, and it is fixedly connected to the workbench 1 by bolts or welding. The position of the other positioning member 2 is adjustable, and it is named as the adjustable positioning member 5.

[0026] The adjustable positioning member 5 is slidably connected to the workbench 1, and the adjustable positioning member 5 is fixedly connected to the workbench 1 by a first adjusting bolt 6 and a first nut 7. The adjustable positioning member 5 is pushed to move as needed to change the distance between it and another positioning member 2; after the distance is adjusted, the position is fixed by tightening the first adjusting bolt 6.

[0027] Each positioning member 2 corresponds to at least one sliding clamping fixing member 3, which clamps the welded part together with the positioning member 2 through sliding clamping; the sliding clamping fixing member 3 is slidably connected to the workbench 1, and the sliding clamping fixing member 3 and the workbench 1 are connected through a second adjusting bolt 8 and a second nut 9.

[0028] The U-shaped support and hanger is composed of two vertical rods 20 and a horizontal rod 19. The specific use is as follows:

[0029] First, adjust the position of the adjustable positioning member 5 according to the spacing width of the U-shaped support and hanger to be welded, and ensure that after the vertical rod 20 and the horizontal rod 19 are placed on the workbench 1, the two end surfaces of the horizontal rod 19 are in contact with the end side surfaces of the two vertical rods 20. Adjust the position of the positioning member 2 corresponding to the sliding clamping fixing member 3, so that the width between the sliding clamping fixing member 3 and the corresponding positioning member 2 is slightly larger than the width of the vertical rod 20, and then tighten the second adjusting bolt 8.

[0030] After adjustment, the two vertical rods 20 are placed between each sliding clamping fixture 3 and the corresponding positioning member 2; and the ends of the two vertical rods 20 are respectively pressed against the corresponding right-angle positioning parts 4. Then, the two end sides of the cross bar 19 are fitted with the inner side of the right-angle positioning part 4; the two end surfaces of the cross bar 19 are fitted with the end side surfaces of the two vertical rods 20. Finally, the vertical rod 20 and the cross bar 19 are welded.

[0031] Furthermore, a variety of structures can be used to achieve sliding connection. For example, a horizontal plate 10 is fixedly connected to the workbench 1, and a slide groove 11 is provided on the horizontal plate 10 to be slidably connected to the adjustable positioning member 5 and the sliding clamping fixing member 3. The width of the slide groove 11 is larger than the diameter of the rod of the first adjusting bolt 6 and the second adjusting bolt 8, and smaller than the head size of the first adjusting bolt 6 and the second adjusting bolt 8. Therefore, by loosening the first nut 7 or the second nut 9, the adjustable positioning member 5 and the sliding clamping fixing member 3 can be pushed to move along the slide groove 11.

[0032] Specifically, the first adjusting bolt 6 passes through the adjustable positioning member 5 (with corresponding through holes) and the slide slot 11 in sequence and is connected to the first nut 7. The second adjusting bolt 8 passes through the sliding clamping fixing member 3 (with corresponding through holes) and the slide slot 11 in sequence and is connected to the second nut 9.

[0033] The transverse plates 10 are preferably provided in two, and the first adjusting bolts 6 and the second adjusting bolts 8 are correspondingly provided in two, respectively.

[0034] Furthermore, a support plate 12 is fixed on the workbench 1, and the crossbar 19 of the U-shaped support bracket can be placed on the support plate 12 to provide better support.

[0035] Furthermore, the width between the sliding clamping fixing member 3 and the corresponding positioning member 2 is slightly larger than the width of the vertical rod 20 to ensure the placement and removal of the vertical rod 20. Therefore, after the vertical rod 20 is placed, there is a certain amount of activity gap between the vertical rod 20 and the sliding clamping fixing and positioning member 2. That is, the vertical rod 20 cannot be completely and effectively clamped and fixed. To this end, the following structural setting is adopted:

[0036] A spring assembly is provided between the first adjusting bolt 6 and the second adjusting bolt 8; the spring assembly includes a connecting plate 13 and a tension spring 14, the connecting plate 13 is rotationally connected to the first adjusting bolt 6, and the second adjusting bolt 8 is slidingly connected to the connecting plate 13; the two ends of the tension spring 14 are respectively fixedly connected to the first adjusting bolt 6 and the second adjusting bolt 8. Specifically, two first nuts 7 are provided on the first adjusting bolt 6, one of the first nuts 7 is used to fix the position of the adjustable positioning member 5, and the other adjusting nut is used to limit the axial movement of the connecting plate 13, and the connecting plate 13 is located between the two first nuts 7.

[0037] By applying tension through the tension spring 14, the first adjusting bolt 6 and the second adjusting bolt 8 can be brought closer together, that is, the minimum gap between the sliding clamping fixture 3 and the adjustable positioning member 5 is in a state. When in use, the sliding clamping fixture is pushed by hand to increase the gap between the sliding clamping fixture 3 and the adjustable positioning member 5, and the tension spring 14 is stretched to generate elastic potential energy; then the vertical rod 20 is placed between the sliding clamping fixture 3 and the adjustable positioning member 5; finally, the external force is removed, and the elastic potential energy is released through the tension spring 14, so that the sliding clamping fixture 3 slides and cooperates with the adjustable positioning member 5 to clamp the vertical rod 20.

[0038] In order not to hinder the normal sliding of the above-mentioned sliding clamping fixture 3 and ensure that the tension spring 14 can pull it to move, the second nut 9 is not tightened; or the upper end of the rod of the second bolt is a bare rod (the length of the bare rod is greater than the thickness of the sliding clamping fixture 3 and the cross plate 10), and even if the second nut 9 is tightened, the sliding clamping fixture 3 will not be fixed.

[0039] When the position of the adjustable positioning member 5 is adjusted, the movement of the adjustable positioning member 5 will drive the second adjusting bolt 8 and the corresponding sliding clamping fixing member 3 to move accordingly through the movement of the above-mentioned spring assembly.

[0040] For the sliding clamping fixture 3 corresponding to another non-adjustable fixture, a tension spring 14 can also be provided, and a tension force is applied by the tension spring 14 to achieve a minimum gap state between the sliding clamping fixture 3 and the non-adjustable positioning fixture 2.

[0041] In this way, it is no longer necessary to adjust the position of the sliding clamping fixture 3 according to the width of the vertical rod 20 , and the clamping force can be applied by the tension spring 14 .

[0042] Furthermore, in order to facilitate pushing, an arc-shaped bending portion 15 is provided on the sliding clamping fixture 3 .

[0043] Furthermore, although the position of each sliding clamping fixture 3 does not need to be adjusted separately by the tension spring 14, in order to increase the clamping force, each positioning member 2 usually has two sliding clamping fixtures 3. Therefore, when placing the vertical rod 20, each sliding clamping fixture 3 needs to be pushed, which is inconvenient.

[0044] To this end, a cam mechanism is provided between the first adjusting bolt 6 and the second adjusting bolt 8; the cam mechanism includes a rotating shaft 16, a cam 17 and a push plate 18; the rotating shaft 16 is rotatably connected to the second adjusting bolt 8; the push plate 18 is fixedly connected to the connecting plate 13; the cam 17 is fixed on the rotating shaft 16 and can contact the push plate 18. Specifically: two cams 17 are provided on one rotating shaft 16, and each cam 17 cooperates with a corresponding push plate 18. That is, by rotating the rotating shaft 16, the two sliding clamping fixing members 3 can be driven to move.

[0045] After the position of the adjustable fixing is adjusted, it is fixed by tightening the first adjusting bolt 6; that is, the position of the first adjusting bolt 6 is also fixed. When placing the vertical rod 20, by rotating the rotating shaft 16 counterclockwise, the highest point of the cam 17 on the rotating shaft 16 contacts the push plate 18 (the tension spring 14 is stretched), and the second adjusting bolt 8 and the corresponding sliding clamping fixing 3 are pushed to move; the distance between the sliding clamping fixing 3 and the adjustable fixing increases. At this time, the vertical rod 20 can be easily placed.

[0046] After the vertical rod 20 is placed, the rotating shaft 16 is rotated in the opposite direction to make the lowest point of the cam 17 contact the push plate 18, and under the pull of the tension spring 14, the sliding clamping fixture 3 slides and cooperates with the adjustable positioning member 5 to clamp the vertical rod 20.

[0047] For the sliding clamping fixture 3 corresponding to another fixture whose position cannot be adjusted, the above concept can also be adopted to set a cam mechanism for control. Specifically, it is selected and designed according to the actual situation.

[0048] Only the preferred embodiments of the present invention are described in detail above, but the present invention is not limited to the above embodiments.
