[0036] like Figure 1 to Figure 4 As shown, the support frame that is easy to disassemble and assemble provided by the embodiment of the present invention includes: a connecting component, which includes: a first connecting member 1, which is provided with a first cylindrical groove 3 on each side of the four sides; a second connecting member 2, which is provided with two, which are respectively arranged above and below the first connecting member 1, and are integrated with the first connecting member 1, and the cross section of the second connecting member 2 is smaller than the cross section of the first connecting member 1, and the top surface of the second connecting member 2 arranged above and the bottom surface of the second connecting member 2 arranged below are both provided with a second cylindrical groove 4; wherein, in the First bolt through holes are provided on the side walls in four directions of the first cylindrical groove 3 and the second cylindrical groove 4; the cylindrical rod body includes a horizontal rod body 6 and a vertical rod body 7. After the horizontal rod body 6 is inserted into the first cylindrical groove 3 and the vertical rod body 7 is inserted into the second cylindrical groove 4, the first bolt 5 in the first bolt through hole is fine-tuned to make the horizontal rod body 6 in a horizontal position and the vertical rod body 7 in a vertical position; a base 8, each vertical rod body 7 at the bottom is connected to a base 8, and a support frame is formed by multiple connecting parts and multiple cylindrical rod bodies.

[0037] In the above embodiment, when specifically set, the cross section of the first connecting member 1 is square or rectangular, preferably square. Through the first cylindrical groove 3 set on the four sides of the first connecting member 1, a horizontal rod 6 can be connected to the front, back, left and right of the vertical rod 7. The cross section of the second connecting member 2 is square or rectangular, preferably square. Through the second cylindrical grooves 4 on the two second connecting members 2, the two vertical rods 7 can be connected together. It should be noted that the first connecting member 1 in this embodiment is provided with the first cylindrical groove 3 in four directions. In fact, when making the first connecting member 1, the first cylindrical groove 3 can be set only in three directions or in two directions as needed, so as to be used at the edge position or right angle of the support frame. Regarding the second connecting member 2, if the connecting member is set at the top, only one second connecting member 2 located below can be set. Regarding the depth of the cylindrical groove, this embodiment does not make a specific limitation, and can be specifically limited according to the length of the vertical rod 7 and the horizontal rod 6. First bolt through holes are provided on the side walls in four directions of the first cylindrical groove 3 and the second cylindrical groove 4. After the horizontal rod 6 is inserted into the first cylindrical groove 3 and the vertical rod 7 is inserted into the second cylindrical groove 4, the first bolt 5 in the first bolt through hole is fine-tuned to make the horizontal rod 6 in a horizontal position and the vertical rod 7 in a vertical position. The advantage of such a setting is that the inner wall of the first cylindrical groove 3 and the outer wall of the horizontal rod 6, and the inner wall of the second cylindrical groove 4 and the outer wall of the vertical rod 7 will not be completely fitted due to errors due to manufacturing reasons. Therefore, the multiple first bolts 5 provided can not only further fix the horizontal rod 6 and the vertical rod 7, but also adjust the horizontality of the horizontal rod 6 and the verticality of the vertical rod 7.

[0038] In one specific embodiment, the support frame that is easy to disassemble and assemble is as follows: Figure 2As shown, it also includes a reinforcement member, which is arranged between the horizontal rod body 6 located at a high position and the horizontal rod body 6 located at a low position, and specifically includes: a first oblique reinforcement member 10, which is placed obliquely, and a semicircular groove 12 is respectively arranged at both ends of the first oblique reinforcement member 10, and a parallelogram groove 14 is arranged at the center position of the first oblique reinforcement member 10, and a cylinder 13 is embedded in the parallelogram groove 14, and the cylinder 13 extends out of the parallelogram groove 14 and a circle of first racks is arranged around the cylinder 13; a second oblique reinforcement member 11, which is placed obliquely and is aligned with the first oblique reinforcement member The first oblique reinforcing member 10 is provided with a semicircular groove 12 at both ends of the first oblique reinforcing member 10, a through hole is provided at the center of the second oblique reinforcing member 11, and a second rack matched with the first rack is provided on the inner wall of the through hole. The second oblique reinforcing member 11 is engaged with the first oblique reinforcing member 10 through the first rack and the second rack. After engagement, the end of the cylinder 13 is exposed from the through hole, and a nut is provided on the end of the cylinder 13 for fixing; wherein the diameter of the semicircular groove 12 is matched with the diameter of the horizontal rod body 6. wherein the semicircular groove 12 is provided at both ends of the first oblique reinforcing member 10 and the semicircular groove 12 is provided at both ends of the second oblique reinforcing member 11, and the specific arrangement is as follows: after the first oblique reinforcing member 10 and the second oblique reinforcing member 11 are placed obliquely, both end surfaces are horizontal surfaces, and an arc groove is provided on both end surfaces, and the groove bottom of the semicircular groove 12 is welded in the arc groove.

[0039] In the above embodiment, the first oblique reinforcement 10 and the second oblique reinforcement 11 are cross-arranged, and the semicircular grooves 12 at the two ends of the first oblique reinforcement 10 and the semicircular grooves 12 at the two ends of the second oblique reinforcement 11 are respectively clamped on the two adjacent horizontal rod bodies 6, so as to further reinforce the horizontal rod body 6. And the two oblique reinforcements do not need to be welded on the horizontal rod body 6, which is convenient for setting and can play a role in reinforcement. In addition, the first oblique reinforcement 10 and the second oblique reinforcement 11 are fixed by the clamping of the first rack and the second rack and the nut, so that the two oblique reinforcements will not rotate relative to each other. In addition, a parallelogram groove 14 is arranged on the first oblique reinforcement 10, and the second oblique reinforcement 11 can be clamped in the parallelogram groove, so that the plane where the first oblique reinforcement 10 is located and the plane where the second oblique reinforcement 11 is located will not be staggered too much, and it is also convenient to make the four semicircular grooves arranged at the ends of the two oblique reinforcements be located on the same plane. During installation, it is necessary to first clamp the semicircular grooves 12 of the first oblique reinforcement 10 and the second oblique reinforcement 11 on the horizontal rod body 6 located below, and then install the horizontal rod body 6 located above, and clamp the horizontal rod body 6 located above in the semicircular grooves 12.

[0040] In one specific embodiment, the support frame that is easy to disassemble and assemble is provided with a layer of flexible material on the groove wall in the semicircular groove 12. The provision of the flexible material enables the horizontal rod body 6 and the semicircular groove 12 to fit tightly.

[0041] In one specific embodiment, the support frame that is easy to disassemble and assemble is as follows: Figure 4 As shown, it also includes a top connecting plate, which includes: a plate body 15, a third cylindrical groove 20 is provided at the middle position of the bottom, and a rectangular groove 16 is provided at both ends; a slider, a slideway is provided on the two opposite side walls of each rectangular groove 16, and a first slider 17 and a second slider 18 are provided in the slideway, the first slider 17 is provided close to the end of the top connecting plate, and the second slider 18 is provided away from the end of the top connecting plate; a spring 19, one end of which is connected to the second slider 18, and the other end is fixed in the inner side of the rectangular groove 16 On the wall; a second bolt 21, which passes through the second bolt 21 through hole set at the end of the plate body 15 and enters into the rectangular groove 16 to abut against the first slider 17, and the second bolt 21 is rotated to move the first slider 17; wherein, among the three vertical rod bodies 7 arranged in sequence, the middle vertical rod body 7 is inserted into the third cylindrical groove 20, and the remaining two vertical rod bodies 7 are respectively inserted between the first slider 17 and the second slider 18 of the two rectangular grooves 16, and by adjusting the second bolt 21, the three vertical rod bodies 7 are all in a vertical state.

[0042] In the above embodiment, since the three adjacent vertical rods 7 are arranged side by side, it is relatively difficult to use a connecting plate to detachably connect them together and adjust the verticality of the vertical rods 7. Therefore, in this embodiment, a third cylindrical groove 20 is set in the middle of the bottom of the top connecting plate, so that the vertical rod 7 in the middle can be inserted into it, and the two vertical rods 7 on both sides can be inserted into the space between the first slider 17 and the second slider 18. By turning the second bolt 21, the position of the second slider 18 can be fine-tuned to ensure that the two vertical rods 7 on both sides are in a vertical state. It should be noted that the spring 19 between the second slider 18 and the inner wall of the rectangular groove 16 is always in a compressed state after the vertical rod 7 is inserted, ensuring that the second slider 18 and the vertical rod 7 are always in a tightly fitted state. After setting multiple top connecting plates, an operating platform can be set on the multiple top connecting plates, or a steel plate can be placed to form a horizontal operating platform.

[0043] In one specific embodiment, the support frame that is easy to disassemble and assemble is provided with third bolt through holes on the two opposite side walls of the third cylindrical groove 20, and a third bolt is provided in the third bolt through hole for adjusting the verticality of the vertical rod 7 inserted into the third cylindrical groove 20.

[0044] In one specific embodiment, the support frame that is easy to disassemble and assemble is provided with a cylinder 9 inside the base 8, and the piston of the cylinder 9 is fixedly connected to the vertical rod body 7 located at the bottom layer. The provision of the cylinder 9 can facilitate the adjustment of the height of the vertical rod body 7 at the bottom layer. Since the ground of the construction site is not necessarily located on the same plane at the construction site, the provision of the cylinder 9 on the base 8 can ensure that the height of the vertical rod body 7 at the bottom layer is consistent.

[0045] In one specific embodiment, the support frame that is easy to disassemble and assemble is provided with two first bolt through holes in each direction around the first cylindrical groove 3, and one first bolt through hole in each direction around the second cylindrical groove 4. The first bolt through holes provided in four directions of the first cylindrical groove 3 are located on different vertical planes, and the first bolt through holes provided in four directions of the second cylindrical groove 4 are located on different horizontal planes.

[0046] In the above embodiment, if the first bolt 5 holes around the first cylindrical groove 3 and the second cylindrical groove 4 are located on different planes, the horizontality of the horizontal rod body 6 and the verticality of the vertical rod body 7 can be further guaranteed, and the problem of shaking due to the four bolt holes being located on the same plane causing the vertical rod body 7 and the horizontal rod body 6 to be not fixed in other positions will not occur.

[0047] In summary, the support frame that is easy to disassemble and assemble provided by the embodiment of the present invention is easy to install, and can also conveniently adjust the horizontality of the horizontal rod body and the verticality of the vertical rod body. After the support frame is used up, it is also easy to disassemble, which not only improves the installation and disassembly efficiency, but also saves a lot of manpower, saving time and effort.

[0048] The number of devices and processing scales described here are used to simplify the description of the present invention. Applications, modifications and variations of the present invention will be obvious to those skilled in the art.

[0049] Although the embodiments of the present invention have been disclosed as above, they are not limited to the applications listed in the specification and the implementation modes, and they can be fully applied to various fields suitable for the present invention. For those familiar with the art, additional modifications can be easily implemented.
