DETAILED DESCRIPTION

[0027] The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0028] like Figure 1 - Figure 4 As shown, the utility model proposes a photovoltaic power supply bracket, including a frame body 1, a support arm 2, a fixing seat 3 and a length-adjustable connecting arm 4; the frame body 1 here can be a support frame made of multiple rods or plates, and the fixing seat 3 can be a rectangular plate.

[0029] One end of the support arm 2 is fixedly connected to the frame 1, such as by bolt connection, welding, bonding, etc., and the other end of the support arm 2 is hinged to the fixing seat 3; one end of the connecting arm 4 is hinged to the frame 1, and the other end is hinged to the fixing seat 3; the fixed connection between the support arm 2 and the frame 1 is located at one end of the frame 1, and the hinge between the connecting arm 4 and the frame 1 is located at the other end of the frame 1. The hinges of the support arm 2, the connecting arm 4 and the fixing seat 3 are respectively located at the two ends of the fixing seat 3. The elongation or shortening of the connecting arm 4 can drive the fixing seat 3 to rotate around the hinge with the support arm 2, so as to achieve the angle adjustment of the solar panel installed on the fixing seat 3. In the specific implementation, the hinge center line between the connecting arm 4 and the frame 1, the hinge center line between the connecting arm 4 and the fixing seat 3, and the hinge center line of the fixing seat 3 around the support arm 2 are parallel. When the length of the connecting arm 4 changes, the fixing seat 3 can rotate around the hinge center line between the fixing seat 3 and the support arm 2.

[0030] The connecting arm 4 includes an arm body 41 and a sleeve 42 slidably connected to the arm body 41. The sleeve 42 is provided with a locking component 5 that can penetrate into the inner cavity of the sleeve 42 and engage or disengage with the positioning groove 6 provided on the arm body 41. The locking component 5 can quickly lock the connecting arm 4 after the length is adjusted to the required length. There are multiple positioning grooves 6, and the multiple positioning grooves 6 are arranged along the length direction of the arm body 41. When the positioning grooves 6 are arranged in multiple positions, when the locking component 5 is located in different positioning grooves 6, the length of the connecting arm 4 is different, so that the connecting arm 4 has multiple adjustable lengths.

[0031] Furthermore, the locking component 5 includes a guide tube 51 fixedly connected to the end of the sleeve 42 and a locking rod 52 slidably connected to the guide tube 51. The guide tube 51 is in communication with the sleeve 42. The locking rod 52 can extend into the inner cavity of the sleeve 42 and engage or disengage with the positioning groove 6. When the locking rod 52 engages with the positioning groove 6, the locking rod 52 extends out of the end of the guide tube 51 away from the sleeve 42. For ease of use, a handle 10 can be provided at the end of the locking rod 52 extending from the guide tube 51, so that the staff can hold the handle 10 to pull the locking rod 52. The guide tube 51 is fixedly connected to the sleeve 42 by welding. A through hole for the locking rod 52 to pass through is provided on the side wall of the sleeve 42 opposite to the guide tube 51. The locking rod 52 extends into the inner cavity of the sleeve 42 through the through hole. In order to increase the contact area between the guide tube 51 and the sleeve 42, and thus increase the connection strength between the two, the aperture of the through hole can be set to be the same as the outer aperture of one end of the guide tube 51 close to the sleeve 42. During installation, one end of the guide tube 51 is inserted into the through hole and installed by interference fit. To further improve the connection strength, it can be fixed by welding. By designing the locking component 5 to have a pull-out locking rod 52, the locking rod 52 penetrates into the inner cavity of the sleeve 42 and engages or disengages with the positioning groove 6 provided in the arm body 41, thereby locking the extension length of the connecting arm 4. The effectiveness of adjusting the length of the telescopic rod is achieved, and compared with the prior art, it avoids the problem of rust easily generated by bolt connection, which leads to difficulty in disassembly of the bolts. The bracket has a simple structure and is easy to assemble and use.

[0032] Furthermore, there are two arms 41, which are slidably inserted at the two ends of the sleeve 42 respectively; the two arms 41 are connected to the sleeve 42 respectively through a locking component 5. Both ends of the sleeve 42 are formed with a locking area, and the locking area is connected to the arm 41 in an overlapping manner. The outer wall of the sleeve 42 is located in the locking area and the locking component 5 is installed, and the extension length of the two arms 41 is locked by the locking component 5.

[0033] The ends of the two arms 41 away from each other are each provided with a first connecting ear 11, the frame 1 and the fixing seat 3 are each provided with a second connecting ear 12 adapted to the first connecting ear 11, and the first connecting ear 11 is connected to the corresponding second connecting ear 12 via a rotating shaft.

When adjusting the tilt angle of the fixing base 3, the length of the connecting arm 4 can be adjusted.

[0035] The positioning groove 6 is an annular groove opened along the circumferential direction of the arm body 41. That is, the center line of the annular groove is colinear with the center line of the arm body 41. It should be pointed out that the annular groove is only a preferred structural form and does not constitute a limitation of the present utility model. In practical applications, multiple grooves distributed along the length direction of the arm body 41 are sufficient.

[0036] The guide tube 51 has a receiving chamber 501 in which an elastic component 502 for driving the locking rod 52 to reset is installed. The elastic component 502 is a compression spring. By providing the elastic component 502, the locking component 5 can be locked to prevent it from falling off.

[0037] The locking rod 52 is fixedly welded with a limiting ring 7 at one end close to the sleeve 42, and the limiting ring 7 is sleeved on the locking rod 52; the compression spring is sleeved on the locking rod 52, one end of the compression spring abuts against the limiting ring 7, and the other end abuts against the inner wall of the accommodating cavity 501 at one end away from the sleeve 42; the compression spring stretches to drive the locking rod 52 to engage with the positioning groove 6. When in use, the handle 10 of the locking rod 52 is pulled, the compression elastic component is deformed, the end of the locking rod 52 is separated from the positioning groove 6, and the sleeve 42 and the arm body 41 can slide freely, which is simple to operate and easy to adjust, and does not require the help of other external auxiliary tools.

[0039] The clamp 9 includes a fixed clamp ring 901 and a movable clamp ring 902 of an arc structure. The fixed clamp ring 901 is fixedly connected to the frame 1, and both sides of the fixed clamp ring 901 are connected to the movable clamp ring 902 through bolt assemblies.

[0040] When in use, the bottom end of the column 8 is fixedly connected to the infrastructure by bolts, so that the position of the column 8 is fixed, and the side of the frame 1 away from the fixing seat 3 can be fixedly connected to the column 8 by the clamp 9. After the frame 1 is installed on the column 8, the frame 1 is parallel to the column 8. In order to improve the connection strength between the frame 1 and the column 8, two clamps 9 can be provided, and the two clamps 9 are respectively provided at both ends of the frame 1.

[0041] The photovoltaic power supply bracket designed in the present application proposal has a connecting arm 4 whose one end is hinged to the fixed plate and the other end is hinged to the frame body 1, and the length of the connecting arm 4 can be extended or contracted. The connecting arm 4 includes an arm body 41 and a sleeve 42 slidably connected to the arm body.
