[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely for explaining the present utility model and are not intended to limit the present utility model.

[0026] To address the technical problem that traditional carbon steel base plates used for fixing square tubes are exposed, unsightly, and take up a lot of space, this utility model provides a base kit that can improve space utilization and is more aesthetically pleasing.

[0027] It should be noted that the base kit described in this utility model is used for, but not limited to, square tubes, etc. For ease of explanation, this utility model only uses a base kit applied to a square tube as an example for explanation. The principle of a base kit applied to other types of equipment is essentially the same as that applied to square tubes, and will not be described in detail here.

[0028] Please see Figures 1-7 ,in Figure 1 This is a schematic diagram of the structure of a base kit in one embodiment of the present utility model. The base kit includes a first block 1, an expansion screw 2, and a dovetail screw 3. The first blocks 1 are arranged in pairs, and both first blocks 1 are right-angled trapezoids with their inclined surfaces facing away from each other. A first clearance hole 11 is provided on the inclined surface of the first block 1, and a first connecting hole 12 is provided on the bottom surface of the first block 1. One end of the expansion screw 2 extends into the first connecting hole 12 and is fixedly connected to the ground. One end of the dovetail screw 3 penetrates the side wall of the first block 1.

[0029] In this embodiment, the expansion screw 2 and the first connecting hole 12 form a sleeve structure for the square tube 5. The dovetail wire 3 is used for reinforcement to ensure the stability of the square tube 5 after it is erected. Furthermore, the pair of first blocks 1 allows workers to adjust the distance between the two first blocks 1 to accommodate square tubes 5 of different widths, saving material costs and effectively reducing the space occupied by the traditional carbon steel base plate, making it more aesthetically pleasing.

[0030] In one embodiment, a second block 4 is also included. The volume of the second block 4 is larger than that of the first block 1. The second blocks 4 are arranged in pairs. Both second blocks 4 are right-angled trapezoids and their inclined surfaces are opposite to each other. The inclined surfaces of the second blocks 4 are provided with second clearance holes 41, and the bottom surface of the second blocks 4 is provided with second connecting holes 42. One end of the expansion screw 2 extends into the second connecting hole 42 and is fixedly connected to the ground.

[0031] In this embodiment, the function of the second block 4 is that when the first block 1 is not applicable to a larger square tube 5, the second block 4 can be used instead. That is, the first block 1 is suitable for a square tube 5 of one specification, and the second block 4 is suitable for a square tube 5 of another specification.

[0032] In one embodiment, a third connecting hole 43 is provided on the top surface of the second block 4, and a bolt 44 is fitted inside the third connecting hole 43. One end of the bolt 44 extends into the first connecting hole 12 and the third connecting hole 43 and is used to fix the first block 1 to the top of the second block 4.

[0033] In this embodiment, when the square tube 5 is too long, it is convenient to use the first block 1 and the second block 4 together. The connection area with the square tube 5 is increased by the first block 1 and the second block 4, thereby improving the stability of the square tube 5.

[0034] In one embodiment, the first connecting hole 12 and the third connecting hole 43 have the same diameter.

[0035] In this embodiment, it is convenient to achieve a fixed connection using bolts 44 of the same specification.

[0036] In one embodiment, both the first clearance hole 11 and the second clearance hole 41 are through holes.

[0037] In this embodiment, the raw materials used to make the first block 1 or the second block 4 are saved.

[0038] In one embodiment, the first connecting hole 12 and the second connecting hole 42 have the same diameter.

[0039] In this embodiment, when the first block 1 or the second block 4 is fixedly connected to the cement ground 6, only one type of expansion screw 2 is needed, and there is no need to carry multiple types of expansion screw 2.

[0040] In one embodiment, the bottom surface of the first block 1 and the top surface of the second block 4 have the same shape and size.

[0041] In this embodiment, when the first block 1 and the second block 4 are used together, the bottom surface of the first block 1 and the top surface of the second block 4 can completely overlap, thereby making each side surface of the first block 1 and each side surface of the second block 4 coplanar. This is more conducive to fixing the square tube 5 with a higher height when the first block 1 and the second block 4 are used together.

[0042] In one embodiment, the top surface of the second block 4 is fixedly connected with a protrusion 45, and the bottom surface of the first block 1 is provided with a groove 13, with the protrusion 45 and the groove 13 being adapted to each other.

[0043] In this embodiment, by setting the protrusion 45 and the groove 13, the problem of the first block 1 and the second block 4 rotating relative to each other and affecting the rotation of the bolt 44 is avoided during the process of fixing the first block 1 and the second block 4 with the bolt 44.

[0044] In one embodiment, the inclined surface of the first block 1 is parallel to the inclined surface of the second block 4.

[0045] In this embodiment, when the first block 1 and the second block 4 are used together, the inclined surface of the first block 1 and the inclined surface of the second block 4 are coplanar, which facilitates the installation of the square tube 5.

[0046] In one embodiment, the edges of the first block 1 and the second block 4 are both rounded.

[0047] In this embodiment, scratches are avoided and the device is easy for staff to hold.

[0048] To better understand this utility model, the following is combined with... Figures 1 to 7 The technical solution of this utility model is described in detail below:

[0049] By combining and varying the first block 1 and the second block 4 in various ways, the structure of this utility model is applicable to square tubes 5 of various specifications.

[0050] ① When the first block 1 is used alone, one method is to set the inclined surfaces of two first blocks 1 opposite each other, and by adjusting the distance between the two first blocks 1, it can be used for square tubes 5 of different widths; another method is to set four first blocks 1 in pairs, with each first block 1 fitting inside the four corners of the square tube 5, and by adjusting the distance between the pairs of first blocks 1, it can be used for square tubes 5 with larger widths and greater thicknesses; in both methods, holes matching the expansion screws 2 are drilled in the cement ground 6, and the expansion screws 2 are passed through the first connecting hole 12 and the holes drilled in the cement ground 6 in sequence, and the expansion screws 2 are tightened through the first clearance hole 11 to achieve a fixed connection between the first block 1 and the cement ground 6. Finally, the dovetail screws 3 are passed through the side walls of the square tube 5 and the first block 1 in sequence to obtain the reinforced square tube 5 (see Figure 1 and Figure 2 );

[0051] ② When the second block 4 is used alone, in one method, the inclined surfaces of the two second blocks 4 are set opposite each other. By adjusting the distance between the two second blocks 4, it can be used for square tubes 5 of different widths (see...). Figure 3 and Figure 4 In another way, the four second squares 4 are paired up, with each second square 4 fitting inside the four corners of the square tube 5. By adjusting the distance between the pairs of second squares 4, this method can be adapted to square tubes 5 with larger widths and greater thicknesses (see...). Figure 6 and Figure 7 Both methods involve drilling holes in the cement ground 6 that are compatible with the expansion screws 2, and then passing the expansion screws 2 through the second connecting hole 42 and the holes drilled in the cement ground 6 in sequence. The expansion screws 2 are then tightened through the second clearance hole 41 to achieve a fixed connection between the second block 4 and the cement ground 6. Finally, the dovetail wires 3 are passed through the square tube 5 and the side wall of the second block 4 in sequence to obtain the reinforced square tube 5.

[0052] ③ When the first block 1 and the second block 4 are used together, the first block 1 is placed on top of the second block 4, the protrusion 45 is embedded in the groove 13, and the bolt 44 passes through the first connecting hole 12 and the third connecting hole 43 to fix the first block 1 and the second block 4 together. The combined structure is suitable for square tubes 5 that are wider and thicker than those in scheme ② above (see Figure 5 The expansion screws 2 are used to pass through the second connecting hole 42 and the pre-drilled hole in the cement floor 6 in sequence to achieve a fixed connection between the assembled structure and the cement floor 6. Finally, the dovetail wires 3 are used to pass through the side walls of the square tube 5 and the first block 1 and the second block 4 in sequence to obtain the reinforced square tube 5.
