Description

plate fixing device

technical field

The present invention relates to mounting a panel to a bracket, in particular to a panel fixing device.

Background technique

At present, when solar panels or other panels are fixed to a frame, two-piece clamps are arranged on the beams of the frame to clamp the edges of the panels, so as to fix the panels on the frame through the clamps.

Clamps are usually made of aluminum extrusions with a consistent cross-section. Therefore, the part of the clamp contacting the plate needs to be isolated by a rubber pad, so as to avoid the rigid clamp exerting concentrated force on the plate and causing damage to the plate when it contacts the plate. At the same time, the surface of the rubber pad is also provided with grooves, so that the surface of the rubber pad can be easily deformed to disperse the pressure on the plate. On the contrary, the aforementioned grooves will make it impossible to form a good surface contact between the rubber pad and the plate, thereby affecting the clamping force.

In addition, the application where the panel is fixed to the frame is usually located outdoors, for example, the solar panel must be placed in a place with sufficient sunlight. The direct exposure of the rubber pad to the light and heat of the sun, coupled with the action of oxygen in the air, will accelerate the aging of the rubber pad, making the rubber pad elastic, and the clamp will lose its grip on the plate.

As shown in FIG. 1 , FIG. 2 , FIG. 3 and FIG. 4 , the base 110 is disposed along a length direction Y and extends outward along a horizontal direction X. In the horizontal direction X, the outer portion of the base 110 forms an extension plate 112 with a lower thickness. The extension plate 112 has one or more fixing structures 112 a , such as fixing holes for bolts to pass through, so as to fix the base 110 to the bracket 300 . The extension plate 112 has the same length as the base 110 or a different length in the length direction Y, and the thickness of the extension plate 112 may be smaller than that of the base 110 . The upper surface of the base 110 is further provided with a vertical wall 114 , and the vertical wall 114 has the same length as the base 110 in the longitudinal direction Y. As shown in FIG.

As shown in FIGS. 1 , 2 , 3 and 4 , the first buffer member 120 covers the upper surface of the base 110 and extends to the surface of the vertical wall 114 . The first buffer member 120 only needs to partially or completely cover the upper surface of the base 110 , and does not need to cover the extension plate 112 . In addition, the base 110 includes a first groove 116 disposed on the upper surface of the base 110 and extending along the length direction Y. As shown in FIG. The first buffer member 120 includes a first positioning rib 122 for inserting into the first groove 116 to fix the first buffer member 120 on the base 110 .

As shown in FIG. 1 , FIG. 2 , FIG. 3 and FIG. 4 , the pressing plate 130 is adjustably disposed on the base 110 , and a clamping space C is defined between the pressing plate 130 , the base 110 and the vertical wall 114 for clamping The space C has a clamping gap in the horizontal direction X for inserting the edge of the board 200 . The pressing plate 130 has the same length as the base 110 in the longitudinal direction Y, and the clamping space C is open at both ends of the longitudinal direction Y, so that the plate 200 inserted into the clamping gap protrudes from both ends of the clamping space C, and also That is, the pressing plate 130 and the base 110 are only used to clamp a part of the edge of the panel 200 , and do not need to cover a single edge of the panel 200 as a whole.

As shown in FIG. 1 , FIG. 2 , FIG. 3 and FIG. 4 , the pressing plate 130 has a clamping protrusion 132 , which is located at the edge of the pressing plate 130 and protrudes toward the bottom plate 112 , and is formed between the clamping protrusion 132 and the bottom plate 112 . A clamping gap is used for inserting the board 200 into the clamping space C through. In addition, the pressing plate 130 has an injection hole 134 which penetrates through the pressing plate 130 and communicates with the clamping space C. As shown in FIG.

As shown in FIG. 1 , FIG. 2 , FIG. 3 and FIG. 4 , the second buffer member 140 is fixed on the lower surface of the pressing plate 130 , especially on the edge of the clamping protrusion 132 . In a specific embodiment, the pressing plate 130 further includes a second positioning rib 136 disposed on the edge of the clamping protrusion 132 and protruding toward the clamping space C; the second buffer member 140 has a second groove 142, The second positioning rib 136 is used to embed the second groove 142 , and the second buffer member 140 is formed to cover the second positioning rib 136 , so that the second buffer member 140 is fixed on the lower surface of the pressing plate 130 , especially the fixing It is located at the edge of the holding protrusion 132 and is at least partially disposed opposite to the first buffer member 120 . The first buffer member 120 and the second buffer member 140 are made of elastic foam materials, such as foam and foam rubber, which can be appropriately deformed after being pressed to balance the pressure distribution.

As shown in FIG. 1 , FIG. 2 , FIG. 3 and FIG. 4 , the locking member 150 connects the pressing plate 130 and the base 110 , so as to fix the pressing plate 130 on the base 110 and adjust the clamping protrusion 132 and the base 110 . The size of the clamping gap is such that the clamping protrusion 132 and the base 110 can jointly tightly clamp the plate 200 . In a specific embodiment, the locking member 150 is a combination of a bolt and a nut. The bolts pass through the through holes of the base 110 and the pressing plate 130 respectively. The clamping protrusions 132 can press the plate member 200 on the base 110 tightly.

As shown in FIGS. 4 and 5 , when the plate 200 is fixed, the distance between the pressing plate 130 and the base 110 is first increased, so that the edge of the plate 200 can be inserted into the clamping space C through the clamping gap . Next, the pressing plate 130 is moved so that the first buffer member 120 and the second buffer member 140 can respectively contact two sides of the plate member 200 . Then, the locking member 150 is adjusted so that the clamping protrusion 132 is pressed toward the plate member 200 . At this time, the first buffer member 120 and the second buffer member 140 will be deformed under pressure, so that the plate member 200 is evenly compressed, and there is no concentrated force, thereby fixing the plate member 200 .

Referring again to FIG. 4 and FIG. 5 , the vertical wall 114 can be used as a limiting member to limit the extreme position of the pressing plate 130 being pressed downward, so as to avoid excessive pressing of the plate member 200 . The thickness of the first buffer member 120 and the second buffer member 140 is determined by the thickness of the plate member 200 . When the pressing plate 130 contacts the top edge of the vertical wall 114 and cannot continue to press down, the first buffer member 120 and the second buffer member 140 The plate 200 must all be accessible and deformed under moderate pressure.

As shown in FIG. 2 , FIG. 3 , FIG. 6 and FIG. 7 , the two covers 160 are respectively used to be combined with both ends of the base 110 and cover both ends of the clamping space C in the longitudinal direction Y. As shown in FIG. In addition, each cover 160 has an opening slot 162 , which is parallel to the horizontal direction, overlaps the clamping gap, and has a width approximately equal to the thickness of the plate 200 . The length of the opening slot 162 matches the length of the plate 200 inserted into the clamping space C. When the plate 200 is inserted into the clamping space C, the plate 200 is also inserted into the opening slot 162 at the same time, so that the bottom end of the opening slot 162 contacts the edge of the plate 200 . When clamping the convex portion 132 and the bottom plate to clamp the plate member 200, the clamping space C can be in a nearly closed state, and only the injection hole 134 is in an open state. At this time, by being shielded by the cover 160 , the first buffer member 120 and the second buffer member 140 located in the clamping space C can be isolated from the outside light and heat, thereby delaying the first buffer member 120 and the second buffer member 140 deterioration.

As shown in FIG. 8 , the injection hole 134 is used for injecting the liquid sealant 170 , so that the sealant 170 fills the clamping space C and overflows the injection hole 134 moderately. The liquid sealant 170 may be a fluid with a high viscosity coefficient such as silica gel. Although there may be a gap between the pressing plate 130 and the vertical wall 114 of the base 110 , the high viscosity coefficient can prevent the liquid sealant 170 from being lost from the gap, and instead fills the gap. After the liquid sealant 170 is cured, the sealant 170 can completely seal the clamping space C, and adhere the base 110 , the first buffer member 120 , the splint 130 , the second buffer member 140 and the plate member 200 together to strengthen the Buffering and fixing effect on the panel 200 .

The fixing portion 131 and the clamping portion 133 have a height difference relative to the base 110 , and the height of the clamping portion 133 relative to the base 110 is greater than the height of the fixing portion 131 relative to the base 110 . The height difference between the fixing portion 131 and the clamping portion 133 makes the pressing plate 130 have a concave section. The concave section is used for the locking member 150 to pass through to be adjustably fixed to the base 110 . The function of the concave section is to increase the strength of the pressure plate 130 without increasing the thickness of the pressure plate 130 , and at the same time, to shorten the length of the locking member 150 .
