[0024] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0025] like Figures 1 to 5 As shown in the figure, a splicing component for photovoltaic panel assembly is disclosed in a specific embodiment of the present invention, including a support frame 100, a top tongue 200, and a spring 300; the two ends of the support frame 100 are open, and a latch 140 is provided on one side of the top; a stop 400 is provided on the inner wall of the bottom of the support frame 100 corresponding to the latch 140; a first guide hole 111 is provided on the side wall of the support frame 100 near the latch, and a second guide hole 121 is provided on the other side wall, the axes of the first guide hole and the second guide hole coincide; the top tongue 200 passes through the second guide hole 121, and the spring 300 is sleeved on the top tongue 200 to provide the top tongue with a pushing force in the direction of the first guide hole; when the top tongue compresses the spring and retracts inward, the top tongue disengages from the first guide hole and is blocked by the stop; when the stop is pressed down, the obstruction of the top tongue is released, and the top tongue pops out and passes through the first guide hole.

[0026] The aforementioned splicing component for photovoltaic panel assembly has a latch that guides the splicing component to engage at the bottom splicing area of ​​the frames of two adjacent photovoltaic panels. When the frame presses against the stop, it releases the obstruction of the top tongue, which then pops outward under the spring force, passing through the holes in the two frames and maintaining its through-hole state. This achieves the engagement of the two frames, effectively preventing easy loosening and separation, and improving the overall structural strength. Furthermore, the assembly can be completed simply by engaging the latch at the splicing point of the photovoltaic panel frame, making it convenient to use and improving work efficiency.

[0027] Furthermore, such as Figure 4 , Figure 5As shown, the support frame 100 includes a base plate 130, a first upright plate 110 and a second upright plate 120 fixedly disposed on both sides of the base plate 130, a first guide hole 111 disposed on the first upright plate 110, and a second guide hole 121 disposed on the second upright plate 120; a protruding frame 150 is provided on one side of the top of the second upright plate 120, and a bayonet 140 is formed between the protruding frame 150 and the first upright plate 110; a downwardly inclined guide surface 151 is provided on the top side of the protruding frame 150 near the first upright plate; this structural design constructs a support frame with open ends and a bayonet that can be inserted into the splicing part of the photovoltaic panel frame, and also forms an flared opening at the top of the bayonet by designing an inclined guide surface, which has an alignment and guiding effect, so that it can be quickly inserted into the splicing part of the photovoltaic panel frame for easy installation; when the top tongue is in the compressed and retracted state, the end face of the top tongue is located on the side of the end face of the protruding frame away from the first upright plate, ensuring that it will not affect the insertion of the photovoltaic panel frame.

[0028] Furthermore, reinforcing ribs are provided at the connection between the base plate and the second upright plate, and at the connection between the second upright plate and the bottom surface of the convex frame, which can enhance the structural strength of the entire support frame.

[0029] Furthermore, such as Figures 1 to 3 As shown, the top tongue 200 includes a first tongue post 210 and a second tongue post 220 connected to each other. The diameter of the first tongue post 210 is larger than the diameter of the second tongue post 220, forming a stepped portion, which provides a force-bearing portion for the subsequent installation of the spring. The diameter of the first tongue post 210 is adapted to the diameter of the first guide hole 111, and the diameter of the second tongue post 220 is adapted to the diameter of the second guide hole 121. The second tongue post passes through the second guide hole, and the end of the second tongue post 220 away from the first tongue post extends out of the outer side of the second upright plate, and a first retaining spring 230 is installed at the end. This effectively limits the movement trajectory of the top tongue and prevents the top tongue from detaching from the support frame. The spring 300 is sleeved on the second tongue post 220 and clamped between the first tongue post 210 and the second upright plate 120. The spring provides an outward pushing force to the first tongue post, so that the top tongue can pop out and pass into the hole of the photovoltaic panel frame after the obstruction is released, achieving the required snap-fit ​​effect.

[0030] Furthermore, the stop 400 includes a spring piece 410, one end of which is connected to the top surface of the bottom plate 130 near the port, and the other end is tilted upwards towards the center; a baffle 420 is fixedly provided on the side of the tilted end of the spring piece 410 near the center of the support frame, and the position of the baffle 420 corresponds to the position of the tongue 200; the baffle 420 is used to block the end of the tongue 200 in the compressed state; after the spring piece is pressed down to the preset position, the baffle moves down and releases the obstruction of the tongue; the simple spring piece structure is used as the force-applying component, which can maintain the effect of the baffle tilting up and blocking the tongue, and can also release the obstruction of the tongue when pressed down, making it convenient to use and operate;

[0031] Furthermore, the other side of the spring sheet slides against the side wall of the first vertical plate. On the one hand, this can maximize the area of ​​the spring sheet so as to make contact with the connection part of the subsequent photovoltaic panel and ensure smooth triggering; on the other hand, it can transfer some of the lateral force to the first vertical plate and improve the overall force of the blocking tongue.

[0032] Furthermore, the spring and the baffle are integrated into one piece. The end of the spring is welded and fixed to the base plate, and the baffle is added to the support frame later, which facilitates actual processing and production.

[0033] Furthermore, such as Figure 3 As shown, the outer wall of the first tongue post 210 is provided with a first slot 211, which has a closed-loop structure around the axis of the first tongue post; as Figure 2 As shown, a locking piece 500 is rotatably mounted on the outer side wall of the first upright plate 110. When the top tongue is in the pop-out state, the first tongue post passes through the first guide hole, and the first locking groove extends out of the outer side of the first upright plate. The locking piece 500, when adjusted and moved into position, can be locked in the first locking groove 211 to lock the end of the first tongue post 210. By locking the top tongue that has protruded out of the outer side of the first upright plate a second time through the locking piece, it can further prevent the top tongue from retracting and disengaging, and maintain an effective locking connection at the connection part of the photovoltaic panel frame.

[0034] Furthermore, such as Figure 6 As shown, the clip 500 includes a retaining spring portion 530, with a first plate 510 and a second plate 520 fixedly disposed on opposite sides of the retaining spring portion 530. The shape of the retaining spring portion 530 is adapted to the shape of the first slot 211, and the retaining spring portion can be engaged in the first slot. The first plate 510 has a first circular hole 511, and the first upright plate 110 has a corresponding second circular hole 112. The first plate 510 is rotatably mounted on the first upright plate 110 via a rotating shaft 600 passing through the first circular hole 511 and the second circular hole 112. The retaining spring portion can be rotated around the rotating shaft to a position where it engages with the first slot. This design allows the clip to be mounted on the support frame, making it a convenient component and preventing improper installation due to missing components. Furthermore, it uses a rotational adjustment method for installation and engagement, facilitating actual installation operations.

[0035] Furthermore, such as Figure 1 , Figure 4 As shown, a pad 160 is fixedly provided on one side of the outer wall of the first upright plate 110. A gap is left between the pad 160 and the first upright plate 110 to form a clamping groove 170. The second round hole penetrates to the outer wall of the pad. The width of the clamping groove 170 is adapted to the thickness of the first plate 510. The first plate 510 is rotated and clamped in the clamping groove 170 by the rotating shaft 600. It can be designed so that the first plate can be inserted into the clamping groove to transfer the local force of the stop to the clamping groove, further preventing the tongue from falling off.

[0036] A soft rubber washer 540 is fixed on the wall surface of the second plate 520 away from the first upright plate 110; when the second plate is placed in the clamping groove, the soft rubber washer is squeezed into the clamping groove, so that the clips are all disengaged from the position of the first guide hole; the position of the clips can be initially limited, especially before they are installed on the frame of the photovoltaic panel, to ensure that they will not block the first guide hole, and naturally will not affect the protrusion of the top tongue;

[0037] Furthermore, the second plate is also provided with through holes, which are used to adjust or grip the second plate, making it easier to apply force to the second plate and disengage it from the clamping groove.

[0038] Furthermore, countersunk holes are provided at both ends of the second round hole, the first plate is placed in the clamping groove, the rotating shaft is inserted into the second round hole and the first round hole, and the two ends are formed into clamps that fit the countersunk holes by pressing, so that the rotating shaft is installed between the first vertical plate and the pad, effectively preventing the clamps from coming off.

[0039] Furthermore, the edges of the clip and the edges of the groove are chamfered. On the one hand, the clip is inserted into the first groove to form a lock; on the other hand, it facilitates the insertion and clamping of the second plate into the groove, preventing the clip from being too loose and wobbling, and preventing it from easily swinging to the first guide hole and affecting the protrusion of the top tongue.

[0040] This utility model has been described through preferred embodiments. Those skilled in the art will understand that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of this utility model. This utility model is not limited to the specific embodiments disclosed herein; other embodiments falling within the scope of the claims of this application are all within the protection scope of this utility model.
