[0002] During the production process, photovoltaic modules need to undergo product testing and inspection, including power-on testing.

[0003] During the power-on testing process, for photovoltaic modules of different widths, the length of the test fixture needs to be adjusted. The current test fixtures with adjustable dimensions usually include a sleeve and a connector that slides between the two ends of the sleeve. The sleeve and the connector are fixed and adjusted with hexagonal screws. The operation is relatively complicated, time-consuming, and labor-intensive. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a time-saving and labor-saving tooling and testing equipment for testing photovoltaic modules.

[0005] To solve the above technical problems, the present invention adopts the following technical solution:

[0007] The locking mechanism includes a rack disposed on the second rod and a locking tooth movably disposed on the first rod and disengagingly engaged with the rack.

[0008] When the locking mechanism is in the locked state, the locking teeth engage with the rack; when the locking mechanism is in the unlocked state, the locking teeth disengage from the rack.

[0009] The tooling also includes an operating mechanism for driving the chuck to move so that the locking mechanism switches between a locked state and an unlocked state.

[0010] In the aforementioned fixture for testing the power-on of photovoltaic modules, optionally, the operating mechanism includes an operating component slidably disposed on a first rod and a connecting component whose two ends are respectively connected to the operating component and the locking teeth. The connecting component is also rotatably connected to the first rod via a rotating shaft. By operating the operating component on the first rod with external force, the connecting component is rotated, thereby causing the locking teeth to move.

[0011] Optionally, the operating mechanism further includes an elastic element disposed between the first rod and the operating member. An external force operates the operating member to compress the elastic element, causing the locking teeth to disengage from the rack. The elastic force of the elastic element causes the locking teeth to tend to engage with the rack.

[0012] Optionally, the elastic element is a spring, the first rod has a receiving groove, the operating member is slidably disposed in the receiving groove, the spring is located in the receiving groove and the two ends of the spring are respectively connected to the groove wall of the receiving groove and the operating member;

[0013] The direction of movement of the operating component and the direction of extension of the axis of rotation are perpendicular to each other.

[0014] Optionally, the rack extends along the length direction of the second rod.

[0015] Optionally, the first rod is hollow, the second rod is slidably inserted into the first rod, and one end of the second rod is located inside the first rod while the other end of the second rod is exposed outside the first rod.

[0016] Optionally, the first rod and the second rod are slidably connected by a telescopic slide rail assembly.

[0017] Optionally, the telescopic slide rail assembly includes a fixed slide rail disposed on one of the two components, the first rod and the second rod, a movable slide rail disposed on the other component, and ball bearings disposed between the fixed slide rail and the movable slide rail.

[0018] Optionally, the telescopic slide rail assemblies are respectively provided on both sides of the locking mechanism or the operating mechanism.

[0019] Optionally, the fixed slide rail is disposed on the inner wall of the first rod, and a groove is formed on the fixed slide rail. The movable slide rail is disposed on the second rod, and the movable slide rail is also slidably disposed in the groove. The ball bearing is disposed between the movable slide rail and the two groove walls of the groove.

[0020] The second technical solution adopted by this utility model is: a testing device for photovoltaic modules, comprising the aforementioned tooling for testing the power-on state of photovoltaic modules.

[0021] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art:

[0022] This utility model's power-on testing fixture can lock and unlock the first and second rods through a simple pressing operation, thereby adjusting the extension and retraction lengths of the first and second rods and thus adjusting the length of the fixture.

[0036] To enable those skilled in the art to better understand the technical solutions in the embodiments of this utility model, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art should fall within the protection scope of this utility model.

[0037] See Figures 1 to 10 The photovoltaic module power-on testing fixture provided in this embodiment includes a first rod 1 and a second rod 2 that slides relative to the first rod 1 along the length direction of the first rod 1. The length of the fixture is adjustable by sliding the second rod 2 on the first rod 1, so as to be suitable for testing photovoltaic modules of different sizes.

[0038] See Figures 1 to 2 The tooling also includes a locking mechanism for locking the first rod 1 and the second rod 2 relative to each other. The locking mechanism includes a rack 3 extending along the length of the second rod 2 and a locking tooth 4 movably disposed on the first rod 1 and disengagingly engaged with the rack 3. The locking tooth 4 engages with the rack 3 at different positions, so that the length of the second rod 2 extending beyond the first rod 1 is different. The locking mechanism has a locked state and an unlocked state. When the locking mechanism is in the locked state, the locking tooth 4 engages with the rack 3; when the locking mechanism is in the unlocked state, the locking tooth 4 disengages from the rack 3.

[0039] The fixture also includes an operating mechanism for driving the movement of the pawl 4 to switch the locking mechanism between a locked state and an unlocked state.

[0040] Depend on Figures 3 to 5 As can be seen, the operating mechanism includes an operating member 5 slidably mounted on the first rod 1, a connecting member 6 whose two ends are respectively connected to the operating member 5 and the locking tooth 4, and an elastic member 8 disposed between the first rod 1 and the operating member 5. Specifically, the first rod 1 has a receiving groove, the operating member 5 is slidably mounted in the receiving groove, the elastic member 8 is a spring located in the receiving groove, and the two ends of the spring are respectively connected to the bottom wall of the receiving groove and the operating member 5. The connecting member 6 is also rotatably connected to the first rod 1 via a rotating shaft. Figure 4 The axis 7 of the rotating shaft extends along the width direction of the first rod 1, and the direction of movement of the operating member 5 and the direction of extension of the axis 7 of the rotating shaft are perpendicular to each other. The direction of movement of the operating member 5 and the direction of extension of the axis 7 of the rotating shaft are also perpendicular to the length direction of the first rod 1.

[0041] When the external force is applied (by pressing), the operating piece 5 slides on the first rod 1, compressing the spring. The sliding of the operating piece 5 drives the connecting piece 6 to rotate around the axis of rotation, causing the locking tooth 4 to disengage from the rack 3. The locking mechanism unlocks, allowing the first rod 1 and the second rod 2 to slide relative to each other. The tooling length is adjustable. When the external force is removed, the spring force is released, the operating piece 5 resets, the connecting piece 6 rotates, causing the locking tooth 4 to engage with the rack 3, the locking mechanism locks, and the first rod 1 and the second rod 2 are fixed relative to each other.

[0042] By simply pressing the operating piece 5, the locking between the first rod 1 and the second rod 2 can be unlocked. Adjust the length of the tooling, confirm that the length is adjusted to the appropriate position, and release the operating piece 5 to lock the first rod 1 and the second rod 2. The on-site operation is convenient, which greatly saves time and costs and improves work efficiency.

[0043] In some embodiments, such as Figure 2 The first rod 1 and the second rod 2 are slidably connected by a telescopic slide rail assembly 9.

[0044] See Figures 9 to 10 , Figure 9 A schematic diagram of the telescopic slide rail assembly is shown. Figure 10 A bottom view of the telescopic slide rail assembly is shown.

[0045] As shown in the figure, the telescopic slide rail assembly includes a fixed slide rail 9a, a movable slide rail 9b disposed on the fixed slide rail 9a, and a ball bearing 9c disposed between the fixed slide rail 9a and the movable slide rail 9b. A groove is formed on the fixed slide rail 9a, the movable slide rail 9b is slidably disposed in the groove, and the ball bearing 9c is disposed between the movable slide rail 9b and the two groove walls.

[0046] The fixed slide rail 9a is fixedly connected to one of the first rod 1 and the second rod 2, and the movable slide rail 9b is fixedly connected to the other of the first rod 1 and the second rod 2. The sliding connection between the first rod 1 and the second rod 2 is achieved by sliding between the movable slide rail 9b and the fixed slide rail 9a.

[0047] In some embodiments, see Figures 4 to 5 The fixed slide rail 9a is fixedly connected to the inner side wall of the first rod 1, and the fixed slide rail 9a is respectively provided on the opposite sides of the operating mechanism.

[0048] See Figures 7 to 8 The movable slide rail 9b is fixedly connected to the outer wall of the second rod 2, and movable slide rails 9b are respectively provided on opposite sides of the rack 3. One movable slide rail 9b is slidably connected to the corresponding fixed slide rail 9a, and the other movable slide rail 9b is slidably connected to the corresponding fixed slide rail 9a. This allows telescopic slide rail assemblies (such as...) to be provided on opposite sides of the locking mechanism or operating mechanism. Figure 2 (As shown).

[0049] To limit the length by which the second rod 2 slides out of the first rod 1, a limiting component is provided between the fixed slide rail 9a and the movable slide rail 9b. The limiting component can be a limiting post or a limiting hole, such as a limiting post on the fixed slide rail 9a and a limiting hole 9d on the movable slide rail 9b (e.g.,...). Figure 10 (As shown).

[0050] In some embodiments, when the fixture is used for power-on testing, the two electrical measuring elements of the testing equipment are respectively sleeved on the two ends of the first rod 1 and the second rod 2. The structure and installation method of the measuring elements are existing technologies and will not be described in detail here.

[0051] With the power-on testing fixture set up above, the locking and unlocking of the first and second rods can be achieved through a simple pressing operation, thereby adjusting the extension and retraction lengths of the first and second rods and thus adjusting the length of the fixture. The on-site operation is convenient, greatly saving time and improving work efficiency.

[0052] It should also be noted that the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features.

[0053] In addition, in the description of this utility model, unless otherwise specified and limited, it should be noted that the terms "installation", "connection" and "connection" should be interpreted broadly. For example, they can refer to mechanical connection or electrical connection, or the internal connection of two components. They can be directly connected or indirectly connected through an intermediate medium. For those skilled in the art, the specific meaning of the above terms can be understood according to the specific circumstances.

[0054] The above embodiments are only used to illustrate the present utility model, and are not intended to limit the present utility model. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present utility model. Therefore, all equivalent technical solutions also fall within the scope of the present utility model. The patent protection scope of the present utility model should be defined by the claims.
