Technical Field
[0001] The utility model relates to the technical field of photovoltaic facilities, in particular to a photovoltaic support fixing screw with a rectangular joint. Background Art
[0002] At present, most photovoltaic brackets are equipped with stone piers at the bottom of the bracket during installation to increase the deadweight of the bottom of the bracket and improve the stability of the bracket when used outdoors. The rectangular joint at the bottom of the photovoltaic bracket needs to be fixedly riveted to the stone pier to achieve fixed installation. During this period, fixed screws are required to fix the rectangular joint to the mounting base on the top of the stone pier. The stability of the fixed screw installation has a great influence on the stability of the overall photovoltaic bracket.
[0003] The existing photovoltaic bracket fixing screw with rectangular joint has the following disadvantages: the fixing screw is only equipped with a nut and a simple gasket, lacks a padding structure that can increase the friction between the two ends of the thread and the bracket joint, and is prone to loosening after long-term outdoor use. To this end, we propose a photovoltaic bracket fixing screw with a rectangular joint. Summary of the invention
[0004] The main purpose of the utility model is to provide a photovoltaic bracket fixing screw with a rectangular joint, which can effectively solve the problems in the background technology.
[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:
[0006] A photovoltaic bracket fixing screw with a rectangular joint comprises a fixing screw, a first gasket and a second gasket, and also comprises a rectangular joint and a mounting seat for being fixed, wherein one side of the rectangular joint and the mounting seat are provided with mounting holes for the fixing screw to pass through, the rectangular joint is inserted into the mounting seat, and the fixing screw is inserted through the mounting holes of the rectangular joint and the mounting seat in sequence, the first gasket and the second gasket are respectively sleeved on both ends of the fixing screw, a first strip anti-skid groove is provided on the surface of the mounting seat away from the rectangular joint, a second strip anti-skid groove is provided on the inner side surface of the rectangular joint, and a third strip anti-skid groove corresponding to the first strip anti-skid groove and the second strip anti-skid groove is provided on one side surface of the first gasket and the second gasket.
[0007] Furthermore, a nut is threadedly sleeved on the tail end of the fixing screw.
[0008] Furthermore, the first gasket and the second gasket are provided with insertion holes corresponding to the fixing screws at the centers.
[0009] Furthermore, screw holes for mounting with photovoltaic stone piers are respectively provided at the bottoms of both ends of the mounting seat.
[0010] Compared with the prior art, the utility model has the following beneficial effects: through the screw fixing assembly composed of the fixing screw, the first gasket and the second gasket, a stable screw mounting structure is provided between the rectangular joint and the mounting seat for installing the photovoltaic bracket, and the gasket with the strip anti-slip groove on the fixing screw cooperates with the rectangular joint and the mounting seat to greatly increase the anti-loosening effect of the fixing screw after assembly, which helps to make the photovoltaic bracket assembly more stable and effectively solves the loosening problem that occurs between the existing photovoltaic bracket and the photovoltaic stone pier after assembly.

[0018] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.
[0019] like Figure 1-6As shown, a photovoltaic bracket fixing screw with a rectangular joint includes a fixing screw 1, a first gasket 3 and a second gasket 4, and also includes a rectangular joint 10 and a mounting seat 9 for being fixed. One side of the rectangular joint 10 and the mounting seat 9 are provided with a mounting hole 11 for the fixing screw 1 to pass through. The rectangular joint 10 is inserted into the mounting seat 9, and the fixing screw 1 is inserted through the mounting holes 11 of the rectangular joint 10 and the mounting seat 9 in turn. The first gasket 3 and the second gasket 4 are respectively sleeved on both ends of the fixing screw 1. The surface of the mounting seat 9 away from the rectangular joint 10 is provided with a first strip anti-skid groove 7, and the inner side surface of the rectangular joint 10 is provided with a second strip anti-skid groove 8. The first gasket 3 and the second gasket 4 are provided with a third strip anti-skid groove 6 corresponding to the first strip anti-skid groove 7 and the second strip anti-skid groove 8. The tail end of the fixing screw 1 is threadedly sleeved with a nut 2.
[0020] The first gasket 3 and the second gasket 4 are provided with a plug hole 5 corresponding to the fixing screw 1 at the center; Figure 1-3 As shown, the insertion hole 5 facilitates the fixing screw 1 to insert the first gasket 3 and the second gasket 4.
[0021] The bottom of both ends of the mounting seat 9 are respectively provided with screw holes 12 for mounting with the photovoltaic stone pier; Figure 1-3 As shown, the screw hole 12 facilitates the installation seat 9 to insert the screw on the photovoltaic stone pier.
[0022] It should be noted that the utility model is a photovoltaic bracket fixing screw with a rectangular joint. When working, the personnel respectively insert the screw hole 12 of the mounting seat 9 into the screw on the photovoltaic stone pier, and then use the nut to tighten the screw on the photovoltaic stone pier, and then insert the rectangular joint 10 on the photovoltaic bracket into the mounting seat 9. During the processing of the rectangular joint 10 and the mounting seat 9, the first strip anti-skid groove 7 and the second strip anti-skid groove 8 are respectively opened on the rectangular joint 10 and the mounting seat 9 to increase the friction between the first gasket 3 and the second gasket 4 and the rectangular joint 10 and the mounting seat 9 after assembly, thereby improving the anti-loosening effect of the fixing screw 1. After inserting into the mounting seat 9, the personnel first sleeves the first gasket 3 on the fixing screw 1, and then inserts the fixing screw 1 through the rectangular joint 10 and the mounting hole 11 of the mounting seat 9, and then sleeves the second gasket 4 on the tail of the fixing screw 1, and then tightens the tail thread sleeve of the fixing screw 1 through the nut 2. At this time, the third strip anti-skid groove 6 of the first gasket 3 and the second gasket 4 are successively abutted against the first strip anti-skid groove 7 and the second strip anti-skid groove 8, so that the friction between the two ends of the fixing screw 1 and the rectangular joint 10 and the mounting seat 9 is greatly increased, which effectively ensures the stability of the installation between the rectangular joint 10 and the mounting seat 9 of the photovoltaic bracket, and has high practicality.
