[0003] Generally, when photovoltaic (PV) distribution boxes are fixedly installed on a wall, an auxiliary mounting structure is required. However, existing mounting structures for PV distribution box installation still have some drawbacks. For example, the installation of existing PV distribution boxes requires multiple bolts and nuts, making installation and disassembly inconvenient. Furthermore, existing distribution boxes lack seismic resistance, which can easily cause the internal electrical components to loosen during use, thus affecting their stability. To address these issues, we propose a PV distribution box mounting base. Utility Model Content

[0004] The purpose of this utility model is to provide a photovoltaic distribution box mounting base to solve the problems mentioned in the background art, such as the need for multiple bolts and nuts to assist in the installation of existing photovoltaic distribution boxes, which makes installation and disassembly inconvenient, and the lack of anti-vibration structure in existing distribution boxes, which can easily cause the electrical components inside the distribution box to loosen during use, thereby affecting the stability of the electrical components inside the distribution box.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a photovoltaic distribution box mounting base, comprising a distribution box body and a support base body, wherein the distribution box body is snapped onto the support base body, the support base body comprises a lower support rod and an upper support rod, the upper support rod and the lower support rod are spaced apart and arranged symmetrically in the upper and lower positions, and positioning components are provided on the outer sides of the upper support rod and the lower support rod;

[0006] The positioning assembly includes an adjusting sleeve and a screw. The screw is threaded to both sides of the adjusting sleeve, and a snap-fit ​​sleeve is provided at the outer end of the adjacent screw. The snap-fit ​​sleeve and the screw are rotatably connected. A limit rod is movably inserted inside the snap-fit ​​sleeve. Both the upper support rod and the lower support rod have guide grooves for the sliding of the limit rod. A retaining plate is provided on the limit rod. A limit nut is threaded to the upper end of the limit rod and is located above the snap-fit ​​sleeve. A return spring is sleeved on the upper side of the limit rod. A limit plate is provided at the lower end of the limit rod, and a flexible strip is glued to the inner side of the limit plate.

[0007] Preferably, the reset spring is located on the inner side of the snap-fit ​​sleeve and above the snap-fit ​​plate.

[0008] Preferably, the flexible strips are spaced apart and are L-shaped.

[0009] Preferably, the center lines of the adjusting sleeve and the screw are collinear, and the threads on both sides of the adjusting sleeve have opposite directions.

[0010] Preferably, the limiting plates are arranged symmetrically on the left and right, and the included angle of the longitudinal section of the limiting plates is greater than 90 degrees.

[0011] Preferably, the limiting plate is disposed between the upper support rod and the lower support rod, and the limiting plate is symmetrically disposed on both sides of the distribution box.

[0012] Preferably, the center lines of the limiting rod, the screw, and the adjusting screw sleeve are perpendicular to each other.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This type of photovoltaic distribution box mounting base uses upper and lower support rods installed on the wall, with positioning components installed on the corresponding upper and lower support rods. By rotating the adjusting sleeve, the adjacent screws on the left and right sides move simultaneously from the outside to the inside, thereby driving the limiting rod to move from the outside to the inside inside the guide groove.

[0015] 2. This type of photovoltaic distribution box mounting base, through the reset springs distributed in a square on the outside of the distribution box and the flexible strips on the inside of the limiting plate, can alleviate slight vibrations during the use of the distribution box, further ensuring the stability of the electrical components inside the distribution box.

[0022] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example: Please refer to Figure 1-5 This utility model provides a technical solution: a photovoltaic distribution box mounting base, including a distribution box body 1 and a support body 2, wherein the distribution box body 1 is snapped onto the support body 2, as shown below. Figure 1 As shown, the support base 2 includes a lower support rod 21 and an upper support rod 22. The upper support rod 22 and the lower support rod 21 are spaced apart and arranged symmetrically vertically. Positioning components 23 are provided on the outer sides of the upper support rod 22 and the lower support rod 21. It is worth noting that in actual use, both the lower support rod 21 and the upper support rod 22 are fixed to the wall with expansion bolts, and the distance between the lower support rod 21 and the upper support rod 22 is set according to the height of the actual installed distribution box 1.

[0024] Please see Figure 2-5 The positioning component 23 includes an adjusting sleeve 231 and a screw 232. The center lines of the adjusting sleeve 231 and the screw 232 are collinear, and the threads on both sides of the adjusting sleeve 231 have opposite directions. The adjusting sleeve 231 and the screw 232 are both located outside the upper support rod 22 and the lower support rod 21, and the setting direction of the upper support rod 22 and the lower support rod 21 is consistent with the setting direction of the upper support rod 22 and the lower support rod 21. The screw 232 is threaded to both sides of the adjusting sleeve 231, and a snap-fit ​​sleeve 233 is provided at the outer end of the adjacent screw 232. The snap-fit ​​sleeve 233 and the screw 232 are rotatably connected.

[0025] Furthermore, a limiting rod 239 is movably inserted inside the snap-fit ​​sleeve 233, with the center lines of the limiting rod 239, screw 232, and adjusting sleeve 231 perpendicular to each other. Both the upper support rod 22 and the lower support rod 21 have guide grooves 24 for sliding of the limiting rod 239, the width of which is equal to the width of the limiting rod 239. The guide grooves 24 facilitate the sliding guidance of the limiting rod 239.

[0026] Furthermore, a retaining plate 237 is provided on the limiting rod 239, and a limiting nut 238 is threadedly connected to the upper end of the limiting rod 239. The limiting nut 238 is provided to prevent the retaining sleeve 233 from falling off the limiting rod 239. The limiting nut 238 is located above the retaining sleeve 233.

[0027] Furthermore, a return spring 236 is sleeved on the upper side of the limiting rod 239. The return spring 236 is located inside the snap-fit ​​sleeve 233 and above the snap-fit ​​plate 237. By sleeved on the limiting rod 239, and with the return springs 236 distributed in a square pattern on the outside of the distribution box 1, slight vertical vibrations during the use of the distribution box can be mitigated, further ensuring the stability of the electrical components inside the distribution box.

[0028] like Figure 3 and Figure 5 As shown, a limiting plate 234 is provided at the lower end of the limiting rod 239. The limiting plate 234 is located between the upper support rod 22 and the lower support rod 21, and is symmetrically arranged on both sides of the distribution box 1. A flexible strip 235 is glued to the inner side of the limiting plate 234. Adjacent flexible strips 235 are spaced apart and are L-shaped. The flexible strips 235 are made of flexible rubber. With the flexible strips 235, the limiting plates 234 on both sides move inward simultaneously to clamp and fix the distribution box 1. On the one hand, the spaced flexible strips 235 can increase the contact friction between the limiting plate 234 and the distribution box 1, making the fixing of the distribution box 1 sufficiently stable. On the other hand, the elasticity of the flexible strips 235 can reduce the damage to the surface of the distribution box during the fixing operation.

[0029] In this example, the limiting plates 234 are symmetrically arranged on both sides, and the included angle of the longitudinal section of the limiting plates 234 is greater than 90 degrees. For example... Figure 3 The upper end of the limiting plate 234 is provided with an inclined part that slopes outward and downward as shown in the figure, which makes it easy for the limiting plates 234, which are symmetrically arranged on both sides, to be snapped onto the distribution box 1. Due to its shape and the elastic effect of the flexible strip 235, the entire mounting base can be used for fixed installation of distribution boxes with similar sizes, further improving the applicability of the distribution box.

[0030] Working principle: Before installation, the distance between the limiting plates 234 on the left and right sides of this photovoltaic distribution box mounting base is slightly larger than the width of the distribution box to be installed. At this time, it is easy for the distribution box body 1 to be placed between the limiting plates 234 on both sides. By rotating the adjusting sleeve 231, the adjacent screws 232 on the left and right sides move from the outside to the inside at the same time, thereby driving the limiting rod 239 to move from the outside to the inside inside the guide groove 24. By continuously screwing the adjusting sleeve 231 in, the symmetrically arranged limiting plates 234 on the left and right sides can be locked on both sides of the distribution box body 1, and vice versa.

[0031] During this process, the reset spring 236 set on the limit rod 239 can alleviate the slight up-and-down vibration during the use of the distribution box, further ensuring the stability of the electrical components inside the distribution box.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
