DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] For examples, see Figure 1-Figure 3 , this embodiment is a street lamp bracket, including a first lamp pole 10 and a second lamp pole 20, the first lamp pole and the second lamp pole are tubular; the top of the second lamp pole is sleeved on the bottom of the first lamp pole, a connecting shaft 30 is fixed to the top of the first lamp pole, and the two ends of the connecting shaft are rotatably connected with connecting plates 40. When in use, the two sides of the solar cell panel 50 are fixed to the corresponding connecting plates, and the connecting plates are provided with a plurality of fixing holes 40-1 at one side or both sides of the connecting shaft, and the plurality of fixing holes form an arc structure in the longitudinal direction, and the arc structure is coaxially arranged with the connecting shaft; a positioning plate 60 is provided on the second lamp pole, and the end of the positioning plate not connected to the first lamp pole or the second lamp pole is connected to the connecting plates at both ends of the connecting shaft through the fixing holes; a plurality of first through holes are circumferentially provided on the first lamp pole, and a plurality of second through holes 20-1 are provided on the second lamp pole at positions corresponding to the first through holes, and at least one first through hole and a second through hole are pin-connected.

[0023] When the above-mentioned street lamp bracket is in use, the positioning plate can be connected to the connecting plate through the fixing holes. Specifically, the positioning plate and the connecting plate can be connected by pin connection or bolt connection. When the angle of the solar panel needs to be adjusted longitudinally, the positioning plate can be rotated to connect with the connecting plate through different fixing holes to achieve the adjustment of the longitudinal angle of the solar panel; when the solar panel needs to be rotated horizontally, the pin connecting the first through hole and the second through hole can be pulled out, and the first lamp pole can be rotated so that the other first through holes are aligned with the corresponding second through holes, and then the pin can be inserted. It should be noted that in the above-mentioned embodiment, the positioning plate can also be connected to the first lamp pole; in actual use, the lamp head can be directly or indirectly installed on the top of the first lamp pole or the second lamp pole.

[0024] As a preferred embodiment, the first through holes are evenly arranged on the first lamp pole, and the number is 2n, wherein n is an integer greater than 1; the second through holes are evenly arranged on the second lamp pole, and the number is 2m, wherein m is an integer greater than 1; pins 70 are arranged on both sides of the second lamp pole, and the pins pass through the corresponding first through holes and second through holes; the connecting plate is provided with a plurality of fixing holes 40-1 at positions close to both sides; an upward extension portion is provided at one end of the pin located on the outer side of the second lamp pole, and the extension portion forms the positioning plate, wherein the extension portion can be made integrally with or connected to the pin; the diameter of the pin is smaller than the inner diameter of the second through hole; the pin is provided with weak portions at positions corresponding to the inner and outer sides of the second lamp pole, and the weak portions in this embodiment are notches 70-1, and a support point is provided at the bottom end of the pin corresponding to the position of the second through hole 70-2, in this embodiment, the support point is made in the form of a convexity. When the above structure is in use, when the back of the solar energy panel is susceptible to strong wind force, the connecting plate has a tendency to rotate longitudinally under the stress state of the solar panel, so that the positioning plate on the left has a tendency to move upward, and the positioning plate on the right has a tendency to move downward. Due to the existence of the notch, the pin breaks at the notch position when it cannot withstand the effect of wind force. Due to the supporting effect of the support point, the part of the pin at the position of the second through hole forms a lever, which facilitates the notch to break under stress. When the two notches are broken, the solar panel and the first lamp pole and other structures slide down under the action of gravity, thereby lowering the position of the solar panel, which can effectively reduce the effect of high wind force, effectively prevent the connection position of the solar panel from being damaged, and because the position of the solar panel is lowered, the solar panel is not easily broken even if it is separated from the lamp stand. In the above implementation, the notch can use the structure shown in the figure, or it can be set around the pin in a circle, which is not specifically limited here. The support point can be set slightly close to the inner side of the second lamp pole, so that the notch part on the inner side of the second lamp pole is more likely to break first, and then rotate against the inner wall of the second through hole. Under the action of the support point, a lever is also formed, and the notch part on the outer side of the second lamp pole continues to be subjected to force until it breaks; of course, the support point is best located in the middle of the two notches.

[0025] As an embodiment, among the fixing holes on both sides of the connecting plate, the spacing between the two fixing holes on one side is greater than the spacing between the two fixing holes on the other side; in order to facilitate the falling of the first lamp pole, the first through hole and the second through hole are preferably arranged at an angle, and the height of the end close to the outer side of the second lamp pole is higher than that of the other end. Of course, the first through hole and the second through hole can also be arranged horizontally, and the diameter of the first through hole can also be greater than the diameter of the pin. This can be set by those skilled in the art according to actual conditions and will not be repeated here.

[0026] As an implementation method, see Figure 4For the convenience of description, the positioning plate on one side of the second lamp pole is called the first positioning plate, and the positioning plate on the other side is called the second positioning plate. The tops of the first positioning plate and the second positioning plate are provided with connecting parts 60-1 at both sides, and the connecting parts are provided with waist-shaped holes 60-2 that match the fixing holes, wherein the connecting parts of the first positioning plate and the second positioning plate are provided as one piece; the connecting parts of the first positioning plate and the second positioning plate can also be provided separately, and when provided as one piece, the positioning plate or the connecting plate can have a certain elasticity. In actual use, a buffer can also be provided at the bottom end of the second lamp pole.

[0027] In order to adapt to the installation of the solar panel, the top surface of the connecting plate is preferably inclined, and the height of the side with a larger spacing between the two fixing holes is greater than the height of the other side.

[0028] In order to facilitate the installation of the connecting shaft, a downwardly protruding boss 30-1 is provided in the middle of the connecting shaft, and the middle of the boss is recessed inward to form a groove 30-2. The top end of the first lamp pole is inserted into the groove and welded or interference fit with the connecting shaft.
