[0032] Please refer to Figures 1 to 14As shown, the utility model discloses a side tie rod 1, which is used to connect a column 2 to a fixed position 30 on the ground 3. The side tie rod 1 of the utility model comprises a connecting tube body 10, a first upper seat body 11, a second middle seat body 12, a third lower seat body 13 and a linear adjustment member 14. The third lower seat body 13 is rotatably connected to the second middle seat body 12, and the first upper seat body 11 is fixedly connected to one end of the connecting tube body 10. The second middle seat body 12 and the first upper seat body 11 are movably connected through the linear adjustment member 14, so that the linear distance between the second middle seat body 12 and the first upper seat body 11 can be adjusted. The connecting tube body 10 in the utility model adopts a rigid structure, replacing the flexible structure such as steel strands used in the prior art, and its deformation is smaller and the stability is better; and the second middle seat body 12 and the first upper seat body 11 in the utility model are movably connected by the linear adjustment member 14, so that the linear distance between the second middle seat body 12 and the first upper seat body 11 can be adjusted, so that the installation length of the side tie rod 1 can be adjusted, eliminating the installation error.

The rod 1411 of the bolt 141 passes through the second middle seat body 12 and the first upper seat body 11, and the nut 142 is screwed and sleeved on the rod 1411 of the bolt 141. The nut 142 and the head 1412 of the bolt 141 are respectively located on two opposite outer side surfaces of the second middle seat body 12 and the first upper seat body 11. With such arrangement, the operator can adjust the side tie rod 1 at the installation site according to the distance between the column 2 and the fixed position 30. The specific operation process is to screw the nut 142 to adjust the specific position of the nut 142 on the rod 1411 of the bolt 141, that is, when the nut 142 is screwed downward and close to the head 1412 of the bolt 141, the linear distance between the second middle seat body 12 and the first upper seat body 11 can be adjusted to be smaller; when the nut 142 is screwed upward and away from the head 1412 of the bolt 141, the linear distance between the second middle seat body 12 and the first upper seat body 11 can be adjusted to be larger. It can be understood that the rod 1411 of the bolt 141 is provided with an external thread, and the nut 142 is provided with an internal thread. By virtue of the cooperation of the internal and external threads, the nut 142 can be rotated and stopped at any position on the rod 1411 of the bolt 141, so as to ensure that the side tie rod 1 is always properly connected between the top of the column 2 and the fixed position 30 of the ground 3 according to the required length.

[0034] The linear adjustment member 14 also includes but is not limited to other embodiments, such as a screw nut, a ball screw, a cylinder, or a known linear telescopic adjustment mechanism.

[0035] The screw and nut form in other embodiments: the screw is a rod structure, and a threaded structure is provided on the rod. After the screw passes through the first upper seat body 11 and the second middle seat body 12, both ends of the screw are fastened with nuts respectively. When the length needs to be adjusted, the position of the nut at one end can be adjusted;

[0036] The ball screw form in other embodiments: the screw passes through the first upper seat body 11 and the second middle seat body 12, the ball is sleeved on the screw and fixedly connected to one of the first upper seat body 11 and the second middle seat body 12, and the rotation of the screw drives the ball to move linearly, thereby adjusting the distance between the upper seat body 11 and the second middle seat body 12;

[0037] The pneumatic cylinder and oil cylinder forms in other embodiments are as follows: the output shaft of the pneumatic cylinder and oil cylinder passes through the upper seat body 11 and the second middle seat body 12 in sequence, or the output shaft of the pneumatic cylinder and oil cylinder is fixedly connected to a connecting shaft, the connecting shaft passes through the upper seat body 11 and the second middle seat body 12 and is fixedly connected to the output shaft of the oil cylinder, and the distance between the upper seat body 11 and the second middle seat body 12 is adjusted by the extension and contraction of the oil cylinder.

[0038] In addition to the specific embodiments listed above, the linear adjustment member may also be other known linear telescopic adjustment mechanisms, as long as the distance between the upper seat body 11 and the second middle seat body 12 can be adjusted.

[0039] Please refer to Figures 1 to 10 There are two linear adjustment members 14, which are symmetrically arranged on opposite sides of the connecting tube body 10 to provide a balanced adjustment function on both sides. That is, the linear adjustment member 14 on the left and the linear adjustment member 14 on the right need to be adjusted to the same length synchronously, so that the left and right ends of the first upper seat body 11 are synchronously approached or synchronously moved away from the second middle seat body 12. Therefore, the side tie rod 1 of the utility model ensures that the connecting tube body 10 will not be skewed during the adjustment process.

[0040] Please refer to Figure 5 , Figure 6 and Figure 7 The first upper seat body 11 includes a first bottom plate 111 and a first ear plate 112. The first ear plates 112 are a pair and extend from the same side of the first bottom plate 111, in the same direction and in parallel. The connecting tube body 10 is clamped and limited between the pair of first ear plates 112. In a specific embodiment, while the pair of first ear plates 112 clamp and limit the connecting tube body 10, the connecting tube body 10 also needs to be welded and fixed to the inner wall of the first ear plate 112. In this way, the connecting tube body 10 and the first upper seat body 11 are fixed as a whole, which facilitates the active connection between the connecting tube body 10 and the second middle seat body 12 through the first upper seat body 11, so as to realize the extension or contraction of the length of the side tie rod 1.

[0041] Please continue to refer to Figure 5 , Figure 6 and Figure 7 The first ear plate 112 includes a first left ear plate 1121 and a first right ear plate 1122. The first bottom plate 111 includes a left half section 1111 extending from the left side of the first left ear plate 1121, a middle section 1112 connected between the first left ear plate 1121 and the first right ear plate 1122, and a right half section 1113 extending from the right side of the first right ear plate 1122. For details, please refer to Figure 7 The left half section 1111 and the right half section 1113 are provided with first through holes 1001 through which the bolts 141 can pass. That is, the first ear plate 112 is a bilaterally symmetrical structure, which is convenient for clamping and limiting the connecting pipe body 10 in the middle section 1112; the two linear adjustment members 14 are positioned in the left half section 1111 and the right half section 1113 to be exposed to the outside, which is convenient for the installer to perform adjustment operations.

[0042] Please continue to refer to Figure 5 , Figure 6 and Figure 8 The side tie rod 1 of the utility model also includes a rotating connector 15 (in the specific embodiment, a second bolt 151 plus a second nut 152 is used). The second middle seat body 12 includes a second bottom plate 121 and a second ear plate 122. The second ear plates 122 are a pair and extend from the same side, in the same direction and in parallel with the second bottom plate 121. The second ear plate 122 includes a second left ear plate 1221 and a second right ear plate 1222. The second bottom plate 121 includes a left half 1211 extending from the left side of the second left ear plate 1221, a middle part 1212 connected between the second left ear plate 1221 and the second right ear plate 1222, and a right half 1213 extending from the right side of the second right ear plate 1222. The left half 1211 and the right half 1213 are provided with a second through hole 1002 through which the bolt 141 can pass. In other words, the second middle seat body 12 has a substantially identical overall structure to the first upper seat body 11. During installation, the second bottom plate 121 and the first bottom plate 111 can be placed close to each other, and the two first through holes 1001 and the two second through holes 1002 are arranged in alignment on two parallel lines. In this way, the first ear plate 112 and the second ear plate 122 are respectively extended from the opposite directions of the first bottom plate 111 and the second bottom plate 121 that are close to each other, so that the pair of first ear plates 112 can be effectively used to position the upper connecting tube body 10 and the pair of second ear plates 122 can be used to position and clamp the third lower seat body 13 below, thereby achieving the connection of the entire side tie rod 1.

[0043] Please refer to Figures 5 to 8 And compare reference Figure 7 and Figure 8 A reinforcing rib plate 16 is provided between the first bottom plate 111 and the first ear plate 112 and between the second bottom plate 121 and the second ear plate 122. The reinforcing rib plate 16 may be in the form of a triangular plate, which is self-evidently used to enhance strength.

[0044] Please continue to refer to Figures 5 to 8 And compare reference Figure 7 and Figure 8 The difference between the second middle seat body 12 and the first upper seat body 11 is that the first left ear plate 1121 and the first right ear plate 1122 are not provided with through holes, while the second left ear plate 1221 and the second right ear plate 1222 are provided with third through holes 1003 that can allow the rotating connection member 15 to pass through. The second left ear plate 1221 and the second right ear plate 1222 are provided with the third through holes 1003 mainly to allow the rotating connection member 15 to pass through, thereby completing the pivotal connection between the second middle seat body 12 and the third lower seat body 13.

[0045] Please refer to Figure 5 , Figure 6 and Fig. 9 The third lower seat body 13 includes a third bottom plate 131 and a third ear plate 132, and the rotating connecting member 15 passes through the second ear plate 122 and the third ear plate 132; the third ear plate 132 is provided with a fourth through hole 1004 arranged in a straight line with the third through hole 1003. Specifically, the third ear plates 132 are also a pair and extend from the same side, the same direction and in parallel with the third bottom plate 131. That is, the third ear plate 132 includes a third left ear plate 1321 and a third right ear plate 1322. Therefore, a pair of second ear plates 122 are embedded between a pair of third ear plates 132 or a pair of third ear plates 132 are embedded between a pair of second ear plates 122, which not only ensures the structural strength of the third lower seat body 13, but also realizes the pivot connection between the second middle seat body 12 and the third lower seat body 13.

[0046] Please refer to Fig.13 and Fig.14 As shown, a fourth seat body 17 is provided at the other end of the connecting pipe body 10 away from the first upper seat body 11. The fourth seat body 17 includes two connecting plates 171 arranged on both sides of the connecting pipe 10. One end of the connecting plate 171 is fixedly connected to the connecting pipe body 10, and the other end protrudes from the end of the connecting pipe body 10, and is rotatably connected to the mounting seat body 20 (to be described in detail later) of the column 2 through a rotating connecting member 18. Specifically, the rotating connecting member 18 specifically adopts a third bolt 181 and a third nut 182 for use. The third bolt 181 passes through the two connecting plates 171 and the mounting seat body 20 and is limited by the third nut 182, so that the connecting pipe body 10 can rotate relative to the mounting seat body 20, so as to facilitate the installation of the side tie rod 1. Preferably, the fourth seat body 17 is fixedly connected to the connecting pipe 10 by welding. The arrangement of the fourth seat body 17 not only facilitates the installation of the side tie rod 1, but also improves the shear strength and compressive strength of the connecting pipe 10, thereby improving the service life of the side tie rod 1. Preferably, the cross-section of the connecting pipe 10 is a square tube, and in other embodiments, it may also be a round tube.

[0047] Please refer to Figures 1 to 14, especially refer to Figure 1 , Figure 2 , Fig.13 and Fig.14 The utility model also relates to a photovoltaic support system, comprising a column 2 and the side tie rod 1 as described above. Figure 1 and Figure 2 The diagram shows a common use state of a photovoltaic support system to which the side tie rod 1 of the utility model is applied; Fig.13 and Fig.14 The figure shows another use state of the photovoltaic support system to which the side tie rod 1 of the utility model can be applied. The difference between the two use states is: Figure 2 The side tie rod 1 in the embodiment is to connect the top of the column 2 directly and obliquely to a fixed position 30 (such as a foundation object) with a relatively small height on the ground 3, and Fig.13 The side tie rod 1 is to connect the top of the column 2 obliquely to a fixed position 30 with a larger height (for example, another column-like object) and then further fix it on the ground 3. Regardless of the use state, the top of the column 2 is provided with a mounting seat 20, and the side tie rod 1 is obliquely connected between the top of the column 2 and the fixed position 30 on the ground 3 through a rotational connection with the mounting seat 20. That is, the fixed position 30 is not limited to a high or low state, as long as its position on the ground 3 is fixed.

[0048] Specifically, the mounting seat body 20 includes a first extension plate 201 extending horizontally, a second extension plate 202 extending vertically, and a third extension plate 203 fixed to the side of the second extension plate 202. The other end of the connecting tube body 10 is pivotally connected to the third extension plate 203. Such a configuration facilitates rotational connection at the other end of the connecting tube body 10. The side tie rod 1 in the photovoltaic support system of the utility model is pivotally connected at both ends, so the angle can be adjusted according to the needs of the site. The adjustment principle of the utility model can be abstractly understood as, in a right triangle, when the length of one right-angled side is fixed and the length of the other right-angled side is uncertain, the length of the hypotenuse and the size and angle of the two acute angles are uncertain and variable. Therefore, when the length of the side tie rod 1 of the utility model is adjusted, it is bound to require that both its upper and lower ends can be pivotally connected.

[0049] The connecting pipe body 10 in the utility model adopts a rigid structure, replacing the flexible structure such as steel strands used in the prior art, and has smaller deformation and better stability; and the second middle seat body 12 and the first upper seat body 11 in the utility model are movably connected by a linear adjustment member 14 so that the straight-line distance between the second middle seat body 12 and the first upper seat body 11 can be adjusted, thereby being able to adjust the installation length of the side pull rod 1 and eliminating installation errors.

[0050] The above implementation modes are only used to illustrate the present invention and are not intended to limit the technical solutions described in the present invention. The understanding of the present invention should be based on the technical personnel in the relevant technical field. Although the present invention has been described in detail in this specification with reference to the above implementation modes, ordinary technical personnel in the field should understand that the technical personnel in the relevant technical field can still modify or make equivalent substitutions to the present invention, and all technical solutions and improvements thereof that do not depart from the spirit and scope of the present invention should be included in the scope of the claims of the present invention.
