Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the utility model.

[0038] The utility model provides a column assembly.

[0039] In this utility model technical solution, please refer to Figures 1 to 6 The column assembly includes a column body 100 and a column base assembly 200. The column base assembly 200 includes a base plate 210 and a sleeve assembly 220. One end of the sleeve assembly 220 is connected to the base plate 210, and the other end is provided with an insertion port 221a. The column body 100 is inserted into the sleeve assembly 220 through the insertion port 221a and has an interference fit with the sleeve assembly 220.

[0040] The column body 100 is used as a part of the photovoltaic support to support the photovoltaic module. The column body 100 can be a prism or a cylinder or a column with a cross section of other special shapes. The column foot assembly 200 refers to a component used to fix the column. The column foot assembly 200 includes a base plate 210 and a sleeve assembly 220. The base plate 210 is used to connect with the mounting surface, and the mounting surface can be the ground or the roof surface. The sleeve assembly 220 refers to a component for the column body 100 to be inserted. One end of the sleeve assembly 220 is connected to the base plate 210, and the other end is provided with an insertion port 221a. The column body 100 can be inserted into the sleeve assembly 220 through the insertion port 221a, so that the sleeve assembly 220 has a certain protection and limiting effect on the bottom end of the column body 100, reducing the risk of the column body 100 being exposed to the outside and easily corroded and rusted by rain or humid environment. Specifically, the shape of the insertion opening 221a of the sleeve assembly 220 can be the same as or different from the cross-sectional shape of the column body 100, as long as the column body 100 can be inserted into the sleeve assembly 220 so that the sleeve assembly 220 can protect the foot of the column body 100. In addition, the outer shape of the sleeve assembly 220 can be the same as or different from the outer shape of the column body 100. For example, when the column body 100 is a prism, the outer shape of the sleeve assembly 220 can also be a prism, or a cylinder, or a sphere or a hemisphere, etc.

[0041] In order to ensure that the column assembly can be stably installed on the required installation surface, the bottom end of the sleeve assembly 220 is also connected to a bottom plate 210, and the column assembly can be connected to the installation surface through the bottom plate 210, so as to achieve the effect of connecting the entire column assembly to the installation surface. Specifically, the installation surface can be a roof or a ground. When the bottom plate 210 is connected to the installation surface, it can be connected by rivets, bolts, or concrete pouring. During the specific construction, the column body 100 can be first inserted into the sleeve assembly 220, and then the bottom plate 210 can be fixed on the installation surface. Alternatively, the bottom plate 210 can also be first connected to the installation surface, so that the sleeve assembly 220 has a relatively stable state; and then the column body 100 is inserted into the sleeve assembly 220 through the insertion port 221a. Since the column body 100 and the sleeve assembly 220 are interference fit, it can be ensured that the column body 100 can stand stably on the installation surface. The sleeve assembly 220 may only include a sleeve body 221, and the outer diameter of the column is slightly larger than the inner diameter of the sleeve body 221, so that the column body 100 can be inserted into the sleeve body 221 and can abut against the inner wall of the sleeve body 221, thereby achieving an interference fit between the sleeve body 221 and the column body 100. Alternatively, the sleeve assembly 220 includes a sleeve body 221 and a clamping member 222, and the inner diameter of the sleeve body 221 can be larger than the outer diameter of the column body 100, so that a gap is provided between the column body 100 and the inner wall of the sleeve body 221 after the column body 100 is inserted into the sleeve body 221, and finally at least a portion of the clamping member 222 is inserted between the sleeve body 221 and the column body 100 to achieve a clamped state, thereby achieving an interference fit between the column body 100 and the sleeve assembly 220. Specifically, the thickness of at least a portion of the clamping member 222 is larger than the size of the gap formed between the sleeve body 221 and the column body 100. A connecting port may be provided at one end of the sleeve assembly 220 away from the insertion port 221a, thereby reducing the weight of the sleeve assembly 220; the bottom plate 210 may at least partially block the connecting port, or may not block the connecting port. When the bottom plate 210 blocks the connecting port, the column body 100 may abut against the portion of the bottom plate 210 that blocks the connecting port, and a connecting structure for connecting to a mounting surface may be provided on the bottom plate 210, and the connecting structure may be provided at the position of the bottom plate 210 that blocks the connecting port. In addition, the bottom plate 210 may also include a portion connected to the outer edge of the sleeve assembly 220 and extending in a direction away from the edge of the sleeve assembly 220, and the portion may also be provided with a connecting structure for connecting to a mounting surface.

[0042] The technical solution of the utility model ensures the stability of the sleeve assembly 220 by connecting one end of the sleeve assembly 220 to the bottom plate 210. By providing an insertion port 221a at the other end of the sleeve assembly 220, it is convenient for the column body 100 to be inserted into the sleeve assembly 220 through the insertion port 221a, so that the sleeve body can protect the foot of the column body 100, thereby reducing the risk of the column body 100 being corroded by rain or humid environment and rusting, thereby improving the service life of the column assembly. By making the column body 100 and the sleeve assembly 220 interference fit, the risk of the column body 100 being separated from the sleeve assembly 220 can be reduced. In addition, by inserting the column body 100 into the sleeve assembly 220 and making an interference fit with the sleeve assembly 220, the connection between the column body 100 and the column foot assembly 200 is made simpler, reducing the process of connecting the column body 100 to the column foot assembly 200 by welding, and improving the construction efficiency. At the same time, the column body 100 can be pre-inserted into the sleeve assembly 220 before construction, and the column body 200 and the sleeve assembly 220 can be connected after the construction of the column body 100 and the upper structure is completed, which can eliminate the installation stress of the structure and make the structure safer.

[0043] In one embodiment, please refer to Figure 1 and Figure 4 The sleeve assembly 220 includes a sleeve body 221 and a clamping piece 222, and the column body 100 is inserted into the sleeve body 221; at least part of the clamping piece 222 is clamped between the side wall of the sleeve body 221 and the column body 100, and is detachably connected to the sleeve body 221, and the column body 100 and the clamping piece 222 are interference fit.

[0044] By inserting the column body 100 into the barrel body 221 and clamping at least part of the clamping member 222 between the barrel body 221 and the side wall of the column body 100, the interference fit effect of the column body 100 and the sleeve assembly 220 can be achieved, so that the clamping member 222 can squeeze and fix the column body 100 to ensure that the column body 100 can be stably installed in the sleeve assembly 220. By detachably connecting the clamping member 222 and the barrel body 221, during the assembly of the column assembly, the column body 100 can be first inserted into the barrel body 221, and then at least part of the clamping member 222 can be embedded between the column body 100 and the barrel body 221, so that the column body 100 and the column foot assembly 200 are easily installed. In addition, by detachably connecting the clamping member 222 and the barrel body 221, it is convenient to replace the clamping member 222 separately, thereby reducing the replacement cost. Specifically, the clamping member 222 and the barrel body 221 can be detachably connected by means of screw connection, snap connection or plug-in connection.

[0045] It should be noted that during the construction process, the column body 100 can be first inserted into the cylinder body 221, and then the main structure of the upper part of the column body 100 can be installed. At this time, since there is a gap between the column body 100 and the cylinder body 221, there is an adjustment space in the cylinder body 221 for adjusting the column body 100, thereby reducing the risk of deviation during installation and reducing the installation stress during installation. After the main structure of the upper part of the column body 100 is installed, the clamping member 222 is placed in the gap between the column body 100 and the cylinder body 221 according to the position of the adjusted column body 100, and the bottom plate 210 is fixed to achieve the clamping and fixing effect of the clamping member 222 on the column body 100.

[0046] Further, please refer to Figures 1 to 6 The clamping member 222 includes a back plate 2221 and a stiffening plate 2222. The back plate 2221 is clamped between the side wall of the tube body 221 and the column body 100. The stiffening plate 2222 is connected to the side of the back plate 2221 away from the column body 100, and is connected to the back plate 2221 at an angle, and is plugged into the tube body 221.

[0047] By clamping the back plate 2221 between the side wall of the barrel body 221 and the column body 100, the interference fit effect between the column body 100 and the sleeve assembly 220 is achieved. By setting the stiffening plate 2222, the stiffening plate 2222 is connected to the side of the back plate 2221 away from the column body 100, and is connected to the back plate 2221 at an angle, and is plugged with the barrel body 221, so that after the back plate 2221 in the clamping member 222 is inserted between the column body 100 and the barrel body 221, the stiffening plate 2222 can have a good limiting effect on the back plate 2221, reducing the risk of the back plate 2221 moving along the circumferential direction of the barrel body 221. Specifically, the stiffening plate 2222 can be rectangular, square, circular, trapezoidal, triangular, "7"-shaped plate, "T"-shaped plate, etc. The stiffening plate 2222 and the back plate 2221 may be an integral structure, or may be connected in a detachable manner.

[0048] It should be noted that when the stiffening plate 2222 can be connected to the back plate 2221 at an angle, the case where the stiffening plate 2222 is connected to the back plate 2221 at an angle of 0° is not included. The stiffening plate 2222 can pass through the side wall of the cylinder body 221, or it may not pass through the side wall of the cylinder body 221.

[0049] In an example, please refer to Figure 2 and Figure 5The back plate 2221 includes a first connecting section 2221a and a second connecting section 2221b which are connected to each other in a direction from the top end of the cylinder body 221 to the bottom end of the cylinder body 221, at least the second connecting section 2221b is clamped between the cylinder body 221 and the side wall of the column body 100, and the stiffening plate 2222 is connected to the first connecting section 2221a.

[0050] Specifically, only the second connecting segment 2221b of the back plate 2221 is clamped between the barrel body 221 and the side wall of the column body 100; or both the first connecting segment 2221a and the second connecting segment 2221b of the back plate 2221 are clamped between the barrel body 221 and the side wall of the column body 100. It can be understood that when only the second connecting segment 2221b of the back plate 2221 is clamped between the barrel body 221 and the side wall of the column body 100, combined with the solution that the stiffening plate 2222 is connected to the first connecting segment 2221a, the bottom surface of the stiffening plate 2222 is located above the top surface of the barrel body 221. In this solution, it is convenient for the user to insert the second connecting section 2221b between the side wall of the tube body 221 and the column body 100 by holding the first connecting section 2221a and / or the stiffening plate 2222; and this arrangement also makes the top end surface of the tube body 221 itself act as a limiting structure for mutual limitation with the stiffening plate 2222, avoiding the need to set an additional structure on the tube body 221 for mutual limitation with the stiffening plate 2222.

[0051] When the first connecting segment 2221a and the second connecting segment 2221b are both clamped between the barrel body 221 and the side wall of the column body 100, in one example, the thickness dimension of the first connecting segment 2221a is greater than the thickness dimension of the second connecting segment 2221b.

[0052] By placing the first connecting section 2221a of the back plate 2221 close to the top of the barrel body 221, the second connecting section 2221b close to the bottom of the barrel body 221, and the thickness of the first connecting section 2221a is greater than the thickness of the second connecting section 2221b, the back plate 2221 is easily inserted into the gap between the barrel body 221 and the column body 100 through the insertion port 221a, thereby facilitating the effect of inserting the back plate 2221 into the barrel body 221. When the back plate 2221 continues to move toward the bottom plate 210, the first connecting section 2221a of the back plate 2221 is stuck between the barrel body 221 and the column body 100, thereby achieving the effect of interference fit between the column body 100 and the sleeve assembly 220. It should be noted that the thickness dimension of the first connecting segment 2221a is greater than the thickness dimension of the second connecting segment 2221b, which means that the minimum thickness dimension in the first connecting segment 2221a is greater than the maximum thickness dimension in the second connecting segment 2221b, so that the thickness dimension at any position in the first connecting segment 2221a is larger than the thickness dimension at any position in the second connecting segment 2221b.

[0053] Specifically, in the direction perpendicular to the bottom plate 210, the thickness of the first connecting section 2221a is uniform at all locations, or the thickness of the first connecting section 2221a gradually increases from the end close to the bottom plate 210 to the end far from the bottom plate 210; similarly, in the direction perpendicular to the bottom plate 210, the thickness of the second connecting section 2221b is uniform at all locations, or the thickness of the second connecting section 2221b gradually increases from the end close to the bottom plate 210 to the end far from the bottom plate 210. It is sufficient as long as the thickness of the first connecting section 2221a is greater than the thickness of the second connecting section 2221b.

[0054] Furthermore, in one example, Figure 2 As shown, in the direction from the bottom end of the barrel body 221 to the top end of the barrel body 221, the thickness of the first connecting section 2221a gradually increases.

[0055] By gradually increasing the thickness of the first connecting section 2221a from the bottom end of the barrel body 221 to the top end of the barrel body 221, the back plate 2221 can be inserted into the barrel body 221 more smoothly at the beginning, and then gradually squeeze the barrel body 221 and the column body 100, ensuring that the back plate 2221 can squeeze and fix the column body 100. In addition, such a configuration can also avoid the appearance of a step structure on the first connecting section 2221a, reducing the risk of the back plate 2221 and the barrel body 221 or the back plate 2221 and the column body 100 being stuck.

[0056] Based on the solution that the first connecting section 2221a and the second connecting section 2221b are both clamped between the barrel body 221 and the side wall of the column body 100, in another example, as Figure 2 As shown, in the direction from the bottom end of the barrel body 221 to the top end of the barrel body 221, the thickness of the second connecting section 2221b gradually increases.

[0057] By gradually increasing the thickness of the second connecting section 2221b from the bottom end of the barrel body 221 to the top end of the barrel body 221, the back plate 2221 can be inserted into the barrel body 221 more smoothly at the beginning, and then gradually squeeze the barrel body 221 and the column body 100, ensuring that the back plate 2221 can squeeze and fix the column body 100. In addition, such a configuration can also avoid the appearance of a step structure on the second connecting section 2221b, reducing the risk of jamming between the back plate 2221 and the barrel body 221 or between the back plate 2221 and the column body 100.

[0058] Further, please refer to Figures 1 to 6 The side wall of the cylinder body 221 is provided with an avoidance groove 221 b for inserting the stiffening plate 2222 , and the avoidance groove 221 b runs through the top end of the cylinder body 221 .

[0059] By passing the avoidance groove 221b through the top of the tube body 221, the clamping piece 222 can be moved from the top of the tube body 221 to the bottom of the tube body 221 to be inserted into the tube body 221, thereby facilitating the installation process of first installing the column body 100 on the tube body 221 and then installing the clamping piece 222 on the tube body 221, thereby improving the installation efficiency.

[0060] Of course, in other examples, the avoidance groove 221b may not pass through the top of the cylinder body 221. In this case, the clamping piece 222 can be installed on the cylinder body 221 first, that is, the back plate 2221 and the stiffening plate 2222 are moved into the cylinder body 221 through the insertion port 221a, and then the clamping piece 222 is moved along the radial direction of the cylinder body 221 so that the stiffening plate 2222 is inserted into the avoidance groove 221b; finally, the column body 100 is inserted into the cylinder body 221, and the back plate 2221 is clamped between the cylinder body 221 and the column body 100.

[0061] Further, please refer to Figures 1 to 6 The stiffening plate 2222 abuts against the bottom wall of the avoidance groove 221b.

[0062] By making the stiffening plate 2222 abut against the bottom wall of the avoidance groove 221 b , the bottom wall of the avoidance groove 221 b has a good limiting effect on the stiffening plate 2222 , thereby reducing the risk of the stiffening plate 2222 moving toward the bottom plate 210 .

[0063] In an example, please refer to Figures 1 to 3 The stiffening plate 2222 includes a plug-in portion 2222a and a connecting portion 2222b, the plug-in portion 2222a is connected to the back plate 2221; the connecting portion 2222b is connected to the plug-in portion 2222a and abuts against the bottom plate 210, and the connecting portion 2222b is arranged on the side of the cylinder body 221 away from the back plate 2221.

[0064] In the case where the cylinder body 221 is provided with an avoidance groove 221b, the plug-in portion 2222a can pass through the avoidance groove 221b and abut against the bottom wall of the avoidance groove 221b. By connecting the plug-in portion 2222a to the back plate 2221 and passing through the avoidance groove 221b and abutting against the bottom wall of the avoidance groove 221b, the setting of the plug-in portion 2222a can have a good limiting effect on the movement of the back plate 2221 in the direction toward the bottom plate 210 and along the circumference of the cylinder body 221, reducing the risk of the back plate 2221 moving and ensuring that the back plate 2221 has a relatively stable state. By connecting the connecting portion 2222b to the plug-in portion 2222a and abutting against the bottom plate 210, the connecting portion 2222b can play a role in strengthening the strength of the entire stiffening plate 2222, so as to indirectly play a good supporting effect on the column body 100. In addition, by arranging the connection part 2222b on the side of the barrel body 221 away from the back plate 2221, the connection part 2222b and the back plate 2221 can jointly clamp the side wall of the barrel body 221, thereby reducing the risk of relative movement between the clamping member 222 and the barrel body 221.

[0065] Of course, based on the scheme that the stiffening plate 2222 is connected to the first connecting section 2221a of the back plate 2221, and the second connecting section 2221b of the back plate 2221 is inserted into the tube body 221, the stiffening plate 2222 may not need to pass through the avoidance groove 221b, and the avoidance groove 221b may not be provided on the tube body 221. In this scheme, the bottom surface of the plug-in portion 2222a of the stiffening plate 2222 may be located above the top end surface of the tube body 221, and it may or may not abut the top end surface of the tube body 221, while the connecting portion 2222b of the stiffening plate 2222 abuts against the bottom plate 210 and is provided on the side of the tube body 221 away from the back plate 2221.

[0066] In another example, please refer to Figure 4 and Figure 6 The column base assembly 200 further includes a reinforcing rib 230 , which connects the side wall of the cylinder body 221 and the bottom plate 210 .

[0067] By connecting the side wall of the barrel body 221 and the bottom plate 210 with the reinforcing rib 230, the reinforcing rib 230 can improve the connection strength between the barrel body 221 and the bottom plate 210. Specifically, one, two or more reinforcing ribs 230 can be provided. When at least two reinforcing ribs 230 are provided, at least two reinforcing ribs 230 are arranged at intervals along the circumference of the barrel body 221.

[0068] Based on the solution that the column base assembly 200 is provided with the reinforcing rib 230, further, as Figure 4 As shown, the stiffening plate 2222 is overlapped on the top end of the reinforcing rib 230 .

[0069] By overlapping the stiffening plate 2222 on the top of the reinforcing rib 230, the reinforcing rib 230 can provide good supporting and limiting effects on the stiffening plate 2222, thereby improving the supporting strength of the stiffening plate 2222 and reducing the risk of the clamping member 222 moving toward the base plate 210.

[0070] Of course, in other examples, the reinforcing rib 230 may not support the stiffening plate 2222 .
