Description

Technical Field

[0001] This utility model relates to the field of photovoltaic bracket accessories technology, and in particular to an improved photovoltaic bracket steering angle structure. Background Technology

[0002] The unique design of the solar panel mounting system allows the modules to be angled according to different regions, thus fully utilizing local solar energy resources and maximizing the power generation efficiency of the solar panels. Furthermore, detailed analysis and practical application of the photovoltaic module connection methods, material selection, and support load stress analysis have been conducted, resulting in excellent physical properties such as earthquake resistance, wind resistance, snow pressure resistance, and corrosion resistance, enabling the photovoltaic modules to be applied in a wider range of regions.

[0003] like Figure 4 As shown, this is the previous generation of steering angle structure installed on photovoltaic brackets. Its main function is to establish the angle installation operation between the front column, rear column, diagonal beam, and diagonal brace beam, and to realize the combination and fixing operation of photovoltaic brackets at different angles. However, the original photovoltaic bracket steering angle structure has the following shortcomings in actual use: The original steering angle structure only fixes the steering angle to the photovoltaic bracket assembly by rotating and adjusting it through the through hole with fastening bolts. Since there is no other auxiliary locking force, the steering angle is prone to displacement, shaking and abnormal noise after installation, which reduces the stability and load-bearing effect of the steering angle after installation.

[0004] In view of this, it is particularly important to design and manufacture a photovoltaic bracket steering angle structure that can effectively improve the locking force after the steering angle is fixed by fastening bolts and reduce the occurrence of abnormal problems after fixing. Utility Model Content

[0005] The purpose of this utility model is to solve the problem that the original photovoltaic bracket turning angle structure is prone to displacement, shaking and abnormal noise after being fixed to the photovoltaic bracket by fastening bolts, which reduces the fixing effect after the turning angle is installed. Therefore, an improved photovoltaic bracket turning angle structure is proposed.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: An improved photovoltaic bracket steering angle structure includes a steering angle, symmetrically opened fixing waist holes on the front and rear sides of the lower end of the steering angle, and symmetrically opened through holes on the upper sides of the left and right ends of the steering angle. The left and right ends of the steering angle are provided with locking mechanisms on both sides of the through holes for stabilizing and limiting the steering angle after installation.

[0007] As a further description of the above technical solution: The locking mechanism includes guide cylinders symmetrically fixed at the left and right ends of the steering angle and coaxially distributed with the through hole, locking sliders movably installed inside the guide cylinders via a locking part, multiple inner locking teeth fixed in a ring array at the inner end of the locking slider and facing the through hole, and multiple outer convex friction blocks fixed in a ring array on the inner side of the left and right ends of the steering angle and located around the through hole.

[0008] As a further description of the above technical solution: The locking part includes multiple support springs fixed in a ring array on the outer end of the guide slide and anti-reverse triangular blocks fixed on the outer ends of the multiple support springs and engaging with the corners of the locking slider.

[0009] As a further description of the above technical solution: The inner side of the guide slide is provided with a guide groove with an inclined surface distribution between the through hole and multiple internal locking teeth.

[0010] As a further description of the above technical solution: The locking slider is integrally fixed to the outside with an outwardly protruding anti-deviation slider, and the inner side of the guide slide cylinder is provided with an anti-deviation groove for accommodating the anti-deviation slider.

[0011] As a further description of the above technical solution: The locking slider has a through hole in the middle that is coaxial with the through hole and has the same inner diameter.

[0012] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are: In this invention, the original steering angle structure has been scientifically and rationally improved. Guide slides, guide grooves, locking sliders, and inner locking teeth are set on the outer sides of the left and right ends of the steering angle. At the same time, multiple convex friction blocks are set on the inner side of the steering angle. When the fastening bolt is inserted into the steering angle and the photovoltaic bracket for locking, the locking slider on the inner side of the guide slide can slide inward under the action of the fastening bolt. Under the guidance of the guide groove, the multiple inner locking teeth on the locking slider can move synchronously towards the through hole to squeeze the outer wall of the fastening bolt. At the same time, the convex friction blocks on the inner side of the steering angle can contact and squeeze the outer wall of the photovoltaic bracket. This structure can effectively increase the locking force between the steering angle, the photovoltaic bracket, and the fixing bolt, and effectively reduce the occurrence of force offset, shaking, or abnormal noise after the steering angle is installed, thereby improving the stability and load-bearing stability of the steering angle after installation.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1-4 This utility model provides a technical solution: an improved photovoltaic bracket steering angle structure, including a steering angle 1, fixing waist holes 101 symmetrically opened on the front and rear sides of the lower end of the steering angle 1, and through holes 102 symmetrically opened on the upper sides of the left and right ends of the steering angle 1. The left and right ends of the steering angle 1 are provided with locking mechanisms on both sides of the through holes 102 for stabilizing and limiting the steering angle 1 after installation.

[0017] Specifically, such as Figure 1-3 As shown, the locking mechanism includes guide cylinders 2 symmetrically fixed at the left and right ends of the steering angle 1 and coaxially distributed with the through hole 102, locking sliders 3 movably installed inside the guide cylinders 2 via a locking part, multiple inner locking teeth 301 fixed in a ring array at the inner end of the locking sliders 3 and facing the through hole 102, and multiple outer protruding friction blocks 4 fixed in a ring array on the inner side of the left and right ends of the steering angle 1 and located around the through hole 102. When the locking sliders 3 move inward, they can drive the multiple inner locking teeth 301 to retract and slide inward synchronously, thereby increasing the locking force between the fastening bolt and the steering angle 1. The multiple outer protruding friction blocks 4 can effectively increase the contact friction between the steering angle 1 and the photovoltaic end, thereby comprehensively improving the stability effect of the steering angle 1 after installation.

[0018] The locking part includes multiple support springs 201 fixed in a ring array on the outer end of the guide slide cylinder 2 and anti-retraction triangular blocks 202 fixed on the outer end of the multiple support springs 201 and engaged with the corner of the locking slider 3. The locking slider 3 can be guided and slid into the inner side of the guide slide cylinder 2 along the multiple support springs 201, and then the anti-retraction triangular blocks 202 can effectively restrict the locking slider 3 from sliding outward in the guide slide cylinder 2.

[0019] Specifically, such as Figure 1-3 As shown, the inner side of the guide slide cylinder 2 is provided with a guide groove 203 with an inclined surface between the through hole 102 and multiple inner locking teeth 301. The guide groove 203 can guide multiple inner locking teeth 301 to retract and slide inward synchronously when the locking slider 3 slides inward to the inner side of the guide slide cylinder 2, and then contact and abut against the outer wall of the fastening bolt.

[0020] Specifically, such as Figure 1-3 As shown, the locking slider 3 is integrally fixedly connected to an outwardly protruding anti-deviation slider 303. The inner side of the guide slide cylinder 2 is provided with an anti-deviation groove 204 for accommodating the anti-deviation slider 303. The anti-deviation slider 303 and the anti-deviation groove 204 can effectively limit the occurrence of axial deflection of the locking slider 3 in the guide slide cylinder 2, thereby improving the effect of the locking slider 3 sliding inward under the overall force to achieve internal locking of the fastening bolt.

[0021] Specifically, such as Figure 1-3 As shown, the locking slider 3 has a through hole 302 in the middle, which is coaxial with the through hole 102 and has the same inner diameter. This allows the head of the fastening bolt to pass through the through hole 102 and then perform a squeezing, sliding deformation, and locking operation on the subsequent locking slider 3.

[0022] Working principle: In use, the steering angle 1 can be pre-fixed at the designated fixed position of the photovoltaic bracket through the fixing waist hole 101 and fastener. Then, another matching photovoltaic bracket assembly can be taken, and the head of the fastening bolt can be inserted through the through hole 102 on the steering angle 1 and the reserved hole on the photovoltaic bracket assembly. Then, the hexagonal nut can be pre-screwed into the fastening bolt. After the fixing angle of the photovoltaic bracket is adjusted, the operator can tighten the fixing screw. During this process, the locking slider 3 in the guide slide cylinder 2 at both ends of the steering angle 1 can move inward simultaneously. When the multiple inner locking teeth 301 on the inner side of the locking slider 3 come into contact with the guide groove 203, they can deflect and slide towards the through hole 102. The multiple inner locking teeth 301 can move inward synchronously to contact and squeeze the outer wall of the fixing bolt, preventing the fastening bolt from being displaced and shaking under the force in the through hole 102. At the same time, the locking force of the fastening bolt will cause the outer convex friction block 4 on the inner side of the steering angle 1 to contact and squeeze the outer wall of the photovoltaic bracket, thereby improving the locking force between the photovoltaic bracket and the steering angle 1. This comprehensively improves the fastening effect of the steering angle 1 being fixed to the end of the photovoltaic bracket by the fastening bolt.

[0023] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
