Description

Technical Field

[0001] This utility model belongs to the field of photovoltaic bracket technology, specifically relating to a support rod for a photovoltaic bracket whose length is easy to adjust. Background Technology

[0002] With the increasing global demand for sustainable energy, solar photovoltaic technology has developed rapidly. However, the power generation efficiency of solar photovoltaic panels is affected by a variety of factors, among which optimizing the solar radiation angle is one of the key factors in improving power generation efficiency.

[0003] Due to the Earth's tilt and revolution around the sun, the sun's position in the sky changes with the seasons and time of day. To maximize the power generation of solar photovoltaic panels, the angle of the panels needs to be adjusted according to the sun's position to maintain optimal solar radiation reception. Especially in applications with limited space, such as balconies, traditional fixed-angle photovoltaic brackets cannot meet the demands of varying solar altitude angles across different seasons and time periods, resulting in low power generation efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a photovoltaic support rod with adjustable length to solve the problems mentioned in the background art. The photovoltaic support rod provided by this invention has the characteristic of facilitating the adjustment of the length of the support rod, thereby facilitating the adjustment of the photovoltaic panel installation angle.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a support rod for a photovoltaic bracket with adjustable length, comprising a main rod, a locking bolt, and a sub-rod. The sub-rod is slidably inserted into the interior of the main rod. The sub-rod has an adjustment groove, and several stop grooves are provided on the side of the adjustment groove. The end of the main rod has a shaped groove. The locking bolt passes through the shaped groove and the adjustment groove, and an elastic element for tightening the locking bolt is connected to the locking bolt. The end of the main rod is fitted with a protective sleeve, and the protective sleeve has a rotatable limiting plate. The sub-rod has a limiting groove corresponding to the stop groove.

[0006] In order to apply tension to the locking bolt so that when the locking bolt corresponds to the gear slot, the locking bolt can automatically engage into the gear slot, thereby achieving rapid gear positioning, the elastic element is a tension spring, with both ends of the tension spring sleeved on the locking bolt, and the two ends of the tension spring located on both sides of the mother rod.

[0007] In order to limit the locking bolt so that the rod can be retracted after being pulled out, the irregular groove further includes a vertical part, and one end of the vertical part is provided with a hook part.

[0008] To achieve a limiting connection between the protective sleeve and the main rod, limiting holes are further provided on both sides of the end of the main rod. The protective sleeve has protrusions corresponding to the limiting holes. End caps are connected to the end sides of the protective sleeve.

[0009] In order to guide the locking bolt so that it can slide out of the stop groove when the lever is pulled, a first guide slope is provided on the side of the stop groove.

[0010] In order to guide the locking bolts so that they can enter and slide out of the hook portion of the irregular groove, a second guide slope is provided at each end of the adjusting groove.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This utility model uses an elastic element to tighten the locking bolt, which cooperates with the gear slot to achieve quick positioning of the gear. The length of the support rod can be adjusted by directly pulling the sub-rod.

[0031] Example 1

[0032] Please see Figures 1-10 This embodiment provides the following technical solution: a support rod for a photovoltaic bracket with adjustable length, including a main rod 1, a locking bolt 2, and a sub-rod 4. The sub-rod 4 is slidably inserted into the interior of the main rod 1. The sub-rod 4 is provided with an adjustment groove 41, and three stop grooves 42 are provided on the side of the adjustment groove 41. The end of the main rod 1 is provided with a shaped groove 7. The locking bolt 2 passes through the shaped groove 7 and the adjustment groove 41, and an elastic element for tightening the locking bolt 2 is connected to the locking bolt 2. The end of the main rod 1 is fitted with a protective sleeve 6, and the protective sleeve 6 is provided with a rotatable limiting piece 5. The limiting piece 5 is connected to the protective sleeve 6 by screws. The sub-rod 4 is provided with a limiting groove 43 corresponding to the stop groove 42. The limiting piece 5 is inserted into the limiting groove 43 to achieve the limiting of the sub-rod 4 and the main rod 1.

[0033] By adopting the above technical solution, this utility model uses an elastic element to tighten the locking bolt 2, which cooperates with the gear slot 42 to achieve quick positioning of the gear. The length of the support rod can be adjusted by directly pulling the sub-rod 4. After adjustment, the sub-rod 4 and the mother rod 1 are limited by the limiting piece 5 being inserted into the limiting slot 43, making the adjustment of the support rod length simpler and more convenient.

[0034] Specifically, the elastic element is a tension spring 3, with both ends of the tension spring 3 fitted onto the locking bolts 2, and both ends of the tension spring 3 located on both sides of the main rod 1.

[0035] By adopting the above technical solution, when the locking bolt 2 is aligned with the gear position groove 42 by the tension spring 3, the locking bolt 2 can automatically engage in the gear position groove 42 under the tension of the tension spring 3, thereby achieving rapid positioning of the gear position.

[0036] Specifically, the side of the gear slot 42 is provided with a first guide slope.

[0037] By adopting the above technical solution, the locking bolt 2 is guided by the first guide slope, so that when the sub-rod 4 is pulled, the locking bolt 2 can slide out from the stop groove 42.

[0038] Example 2

[0039] The difference between this embodiment and embodiment 1 is that, specifically, the irregular groove 7 includes a vertical part, and one end of the vertical part is provided with a hook part.

[0040] By adopting the above technical solution, the locking bolt 2 is limited by the hook part, so that the rod 4 can be retracted after being pulled out.

[0041] Specifically, the two ends of the adjusting groove 41 are respectively provided with second guide slopes.

[0042] By adopting the above technical solution, the locking bolt 2 is guided by the second guide slope, so that the locking bolt 2 can enter the hook part of the irregular groove 7 and slide out from the hook part of the irregular groove 7.

[0043] Example 3

[0044] The difference between this embodiment and Embodiment 1 is that, specifically, limiting holes 101 are provided on both sides of the end of the female rod 1. The protective sleeve 6 has protrusions 61 corresponding to the limiting holes 101. An end cap 62 is connected to the end side of the protective sleeve 6.

[0045] By adopting the above technical solution, the protective sleeve 6 and the female rod 1 are connected in a limiting manner through the cooperation of the protrusion 61 and the limiting hole 101.

[0046] The method for adjusting the length of the support rod in this invention is as follows:

[0047] 1. Assume that initially the sub-rod 4 is retracted inside the main rod 1. At this time, the locking bolt 2 is embedded in the first gear slot, and the limiting piece 5 is inserted into the corresponding limiting slot 43.

[0048] 2. When it is necessary to increase the length of the support rod, rotate the limiting paddle 5 to separate the limiting paddle 5 from the limiting groove 43, and then pull the sub-rod 4 outward. Under the guidance of the first guide slope, the locking bolt 2 slides out of the first gear groove and enters the adjustment groove 41.

[0049] 3. When the locking bolt 2 corresponds to the second gear slot, the locking bolt 2 is engaged in the second gear slot under the tension of the tension spring 3. If the length is appropriate, the limiting piece 5 is engaged in the limiting slot 43. If it is not appropriate, the sub-rod 4 is pulled to engage the locking bolt 2 in the third gear slot.

[0050] 4. When it is necessary to reduce the length of the support rod, the sub-rod 4 must first be pulled out to its maximum position, such as... Figure 8 As shown, guided by the second guide ramp, the locking bolt 2 moves to the hook portion of the irregular groove 7. At this time, the hook portion of the irregular groove 7 limits the locking bolt 2, allowing the male rod 4 to retract into the female rod 1, as shown. Figure 9 As shown, insert the sub-rod 4 to its maximum position. Under the guidance of the second guide slope, the locking bolt 2 slides out from the hook part of the irregular groove 7. Then, pull the sub-rod 4 outward to adjust the length of the support rod.

[0051] In summary, this invention uses an elastic element to tighten the locking bolt 2, which, in conjunction with the gear slot 42, enables rapid gear positioning. The length of the support rod can be adjusted simply by pulling the sub-rod 4. After adjustment, the limiting piece 5 engages with the limiting slot 43 to limit the sub-rod 4 and the mother rod 1, making the adjustment of the support rod length simpler and more convenient. This invention uses a tension spring 3 to apply tension to the locking bolt 2. When the locking bolt 2 aligns with the gear slot 42, the tension spring 3 causes the locking bolt 2 to automatically engage with the gear slot 42, achieving rapid gear positioning. The irregular groove 7 of this invention includes a vertical section, one end of which has a hook. The hook limits the locking bolt 2, allowing the sub-rod 4 to retract after being pulled out. This invention uses a first guide slope and a second guide slope to achieve automatic adjustment of the locking bolt 2's position.

[0052] 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.
