[0032] Conventional testing fixtures utilize pulley edges to engage PV panels. However, these narrow pulley edges result in poor engagement stability. Furthermore, after prolonged use, the test fixtures can tilt, causing the PV panels to become uneven. This can cause one pulley to disengage while the other pulley engages too tightly, compromising the stability of the PV panel installation.

[0033] Based on this, the present application provides a fixing bracket, such as Figure 1 and Figure 2 As shown, the fixing bracket includes a bracket body 100 and a limiting component.

[0034] For example Figure 2 As shown, the bracket body 100 includes a support base 120 and a pressure base 110 disposed opposite each other. The support base 120 and the pressure base 110 cooperate to clamp and secure the test plate 300. A first sliding assembly is disposed on the side of the pressure base 110 opposite the support base 120. A second sliding assembly is disposed on the side of the support base 120 opposite the pressure base 110. The first and second sliding assemblies cooperate to slide and secure the test plate 300.

[0035] like Figure 3 and Figure 4 As shown, the limiting assembly includes a plurality of limiting members 200 disposed on the side of the pressure seat 110 having the first sliding assembly. The limiting members 200 include a limiting plate and an elastic member 230. The elastic member 230 is disposed between the pressure seat 110 and the limiting plate. The limiting plate has a limiting groove for engaging and fixing the test plate 300. The elastic member 230 is used to elastically compress the limiting plate.

[0036] In this application, a first sliding assembly and a second sliding assembly are respectively provided on the support base 120 and the pressure base 110 of the fixed bracket. During installation, the test plate 300 is directly moved between the support column and the pressure base 110 by sliding, thereby improving installation convenience. Furthermore, this application provides an elastic member 230 and a stopper 200 on the fixed bracket. The elastic force of the elastic member 230 ensures that the stopper 200 firmly presses and fixes the test plate 300 during the pressing process, effectively improving the stability of the test plate 300.

[0037] It can be understood that the test plate 300 in the present application can be a photovoltaic module.

[0038] In some embodiments, as Figure 3 and Figure 4 As shown, the limiting plate includes a fixed plate 210 and a pressure plate 211. The fixed plate 210 is provided with a groove. The pressure plate 211 is slidably disposed in the groove. An elastic member 230 is disposed at the bottom of the groove of the fixed plate 210. By providing the fixed plate 210 and the pressure plate 211, the pressure plate 211 can slide in the groove during the pressing and fixing process and cooperate with the elastic member 230 for elastic compression, thereby further improving the stability during the pressing process.

[0039] In some embodiments, Figure 3 and Figure 4 As shown, the limiting plate also includes a first clamping plate 212 and a second clamping plate 213 both slidably disposed on the fixed plate 210. The first clamping plate 212 and the second clamping plate 213 are relatively disposed in the groove of the fixed plate 210. The pressing plate 211 is located between the first clamping plate 212 and the second clamping plate 213, and a limiting groove is formed between the pressing plate 211, the first clamping plate 212 and the second clamping plate 213. In the present application, the first clamping plate 212 and the second clamping plate 213 are slidably disposed. During the pressing process, the first clamping plate 212 and the second clamping plate 213 can be telescopically slid, thereby increasing the clamping area of the test plate 300 and improving the stability of the test plate 300.

[0040] In some embodiments, as Figure 3 and Figure 4 As shown, the limiting member 200 further includes a first tooth plate 214, a second tooth plate 215, a third tooth plate 216, and a plurality of gears 217. The first tooth plate 214 is disposed between the pressure plate 211 and the elastic member 230, and has teeth on both the side facing the first clamping plate 212 and the side facing the second clamping plate 213.

[0041] The first clamping plate 212 is mounted on the second tooth plate 215, which is slidably mounted on the fixed plate 210. The second tooth plate 215 has teeth on the side facing the first tooth plate 214. The second clamping plate 213 is mounted on the third tooth plate 216, which is slidably mounted on the fixed plate 210. The third tooth plate 216 has teeth on the side facing the first tooth plate 214. Gears 217 are respectively mounted between the first and second tooth plates 214, 215, and between the first and third tooth plates 214, 216. Gears 217 are used by the first tooth plate 214 to drive the second and third tooth plates 215, 216, to move.

[0042] The present application provides a gear 217 transmission structure between the pressure plate 211, the first clamping plate 212, and the second clamping plate 213. During the pressing and installation process, when the pressure plate 211 is pressed and moved toward the bottom of the groove, the first clamping plate 212 and the second clamping plate 213 are driven by the gear 217, and move in a direction away from the bottom of the groove. That is, the extension lengthens the clamping area of the first clamping plate 212 and the second clamping plate 213 on the test plate 300, thereby improving the stability of the pressing and fixing. Furthermore, when the test plate 300 is removed, as the pressing force decreases, the pressure plate 211 rebounds and moves in a direction away from the bottom of the groove. Under the action of the gear 217, the first clamping plate 212 and the second clamping plate 213 move toward the bottom of the groove. That is, the retraction reduces the clamping area of the first clamping plate 212 and the second clamping plate 213, reduces the limiting effect, and facilitates the removal of the test plate 300.

[0043] In some embodiments, Figure 4 As shown, the fixed plate 210 is further provided with a first guide post 218. The first guide post 218 is disposed on a side of the fixed plate 210 near the first clamping plate 212. The second tooth plate 215 is provided with a guide block 220. The guide block 220 has a first guide hole (not shown) that matches the first guide post 218. The guide block 220 is slidably mounted on the first guide post 218. It will be appreciated that to improve the guiding stability of the second tooth plate 215 in driving the first clamping plate 212, multiple first guide posts 218 and guide blocks 220 may be provided.

[0044] In some embodiments, the fixed plate 210 is further provided with a second guide post 219. The second guide post 219 is disposed on a side of the fixed plate 210 proximate to the second clamping plate 213. The third toothed plate 216 is provided with a guide block 220. The guide block 220 has a first guide hole that matches the second guide post 219 and is slidably mounted on the second guide post 219. It is understood that to improve the guiding stability of the third toothed plate 216 in driving the second clamping plate 213, multiple second guide posts 219 and guide blocks 220 may be provided.

[0045] The present application provides a guide column and a guide block 220 to achieve the guided transmission of the second tooth plate 215 and the third tooth plate 216 during the transmission of the gear 217. That is, the guided transmission of the first clamping plate 212 and the second clamping plate 213 improves the limiting effect of the limiting member 200.

[0046] In some embodiments, as Figure 4 As shown, the elastic member 230 includes a fixed post 231 and an elastic body 232 that is sleeved onto the fixed post 231. A second guide hole is defined within the first tooth plate 214 along the direction of movement of the pressure plate 211, and the fixed post 231 is at least partially inserted into the second guide hole (not shown). Alternatively, the elastic body 232 may be a spring or other elastic component. By sleeved the elastic body 232 onto the fixed post 231, the first tooth plate 214 is able to guide movement along the fixed post 231 and, under the action of the elastic body 232, compress and rebound, thereby ensuring the stability of the pressing of the pressure plate 211.

[0047] In some embodiments, as Figure 1 and Figure 2 As shown, the first sliding assembly includes a plurality of first pulleys 111 spaced apart and arranged on a support base 120 .

[0048] In some embodiments, the limiting member 200 is disposed between two adjacent first pulleys 111 .

[0049] In some embodiments, the second sliding assembly includes a plurality of second pulleys 121 spaced apart and disposed on the support base 120 .

[0050] In some embodiments, the fixed support further includes a driver (not shown). The driver is disposed on the pressure seat 110, which is movably disposed on the fixed support. The driver is used to drive the pressure seat 110 and the support seat 120 to press together. Optionally, the driver can be a telescopic cylinder or a lifter.

[0051] In summary, the present application provides a first sliding assembly and a second sliding assembly on the support base 120 and pressure base 110 of the fixed bracket, respectively. During installation, the test plate 300 is directly slid between the support column and pressure base 110, improving installation convenience. Furthermore, the present application provides an elastic member 230 and a stopper 200 on the fixed bracket. The elastic force of the elastic member 230 ensures that the stopper 200 firmly presses and secures the test plate 300 during the pressing process, effectively improving the stability of the test plate 300.

[0052] The technical features of the above embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0053] The above embodiments merely illustrate several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the concept of the present invention, and these variations and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present utility model patent shall be determined by the appended claims.
