Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaics, and more specifically to hardware and door covers with a one-way locking function. Background Art

[0002] Hardware refers to tools made of gold, silver, copper, iron, tin and other metals through processing and casting, which are used to fix things, process things, decorate, etc. In real life, common hardware is generally fixed to other objects by bolts or welding. When bolts are used to assemble hardware and other objects, bolt holes (such as countersunk holes) need to be opened on the corresponding profiles to facilitate the assembly of hardware and other objects together.

[0003] At present, when metal profiles, such as aluminum profiles, are spliced ​​at 45 degrees, almost all of them must use flat corner brackets or angle brackets; the flat corner brackets or angle brackets are provided with a number of threaded holes, and a number of countersunk holes corresponding to the threaded holes in the flat corner brackets or angle brackets need to be processed at the 45-degree splicing end of the aluminum profile, and then screwed. However, some specially designed aluminum profiles have larger cross-sectional dimensions, such as aluminum alloy door frames (indoor door aluminum door frames or aluminum door lintels), and the hole positions for installing flat corner brackets or angle brackets are not consistent with those of aluminum profiles. The wall distance is smaller than the radius of the drill chuck of the drilling equipment, so only an extended twist drill or a milling drill can be used. However, the extended twist drill or the milling drill has insufficient rigidity, and the centering is easily offset and has poor accuracy, resulting in deviations between the countersunk holes in the aluminum profile and the threaded holes in the flat angle code or the angle code. Subsequently, the countersunk holes in the aluminum profile do not correspond to the threaded holes in the flat angle code or the angle code. If a manually held electric drill is used to process the holes, the work intensity is high and the hole position accuracy cannot be guaranteed. Therefore, this is a technical problem that urgently needs to be solved in this field.

[0055] Embodiment 1:

[0056] See also Figure 1-Figure 12As shown, a hardware 100 with a one-way locking function can be applied to profiles, such as door covers, door lintels, suspended ceilings and / or columns, wherein the door cover is a term for architectural decoration, which refers to the two door frames inside and outside the door, and is also directly called the door frame. Its main function is to fix the door leaf and protect the corners and decoration. The doorway without a door is called a lintel. In interior decoration, the lintel is also called a decorative panel for wall covering. It is similar to the door cover, but there are differences in structure: the lintel is generally made into a flat plate, which serves as a decoration and wall protection; and the door cover has a high and low door pier on the side because the door is to be installed. The suspended ceiling refers to a decoration of the top decoration of the living environment of the house. Simply put, it refers to the decoration of the ceiling, which is one of the important parts of interior decoration. The column is one of the important components in the building structure, which has the functions of supporting, shear force transmission, force concentration, defining space, and enhancing rigidity.

[0057] The hardware 100 includes an angle code body 1 and a gasket 2 connected to the angle code body 1. The angle code body 1 includes a horizontal arm 11 and a vertical arm 13 which are perpendicular to each other. The length extension direction of the horizontal arm 11 is perpendicular to the length extension direction of the vertical arm 13. The shapes of the horizontal arm 11 and the vertical arm 13 can both be rectangular. A connecting arm 12 is connected to the side of the horizontal arm 11 close to the vertical arm 13 and the side of the vertical arm 13 close to the horizontal arm 11. It can be understood that the horizontal arm 11 and the vertical arm 13 are connected together through the connecting arm 12. Optionally, the horizontal arm 11, the connecting arm 12 and the vertical arm 13 are an integrated structure to save assembly time. When the hardware is assembled on the profile, it is beneficial to improve the assembly efficiency between the hardware and the profile.

[0058] The gasket 2 includes a horizontal gasket 21 and a vertical gasket 22. At least one horizontal gasket 21 is connected to the horizontal support arm 11. Optionally, the number of horizontal gaskets 21 can be one, two or three, which can be increased or decreased according to actual conditions. In this embodiment, the number of horizontal gaskets 21 is only two as an example. When the number of horizontal gaskets 21 is more than two, the two horizontal gaskets 21 can be arranged along the length direction of the horizontal support arm 11. At least one vertical gasket 22 is connected to the vertical support arm 13. Optionally, the number of vertical gaskets 22 can be one, two or three, which can be increased or decreased according to actual conditions. In this embodiment, the number of vertical gaskets 22 is only two as an example. When the number of vertical gaskets 22 is more than two, the two vertical gaskets 22 can be arranged along the length direction of the vertical support arm 13.

[0059] Both the horizontal gasket 21 and the vertical gasket 22 include a gasket body 210, and the gasket body 210 includes a gasket body portion 210a and a connecting portion 210b. The gasket body portion 210a is fixedly connected to the side of the connecting portion 210b close to the gasket body portion 210a, and the connecting portion 210b is located on the side of the gasket body portion 210a close to the connecting arm 12. An approximately convex structure is formed between the gasket body portion 210a and the connecting portion 210b. Specifically, the width of the gasket body portion 210a along the width direction of the gasket body 210 is greater than the width of the connecting portion 210b along the width direction of the gasket body 210, which is conducive to the subsequent design of pad claws 23 on the opposite sides of the connecting portion 210b along the width direction of the gasket body 210; optionally, the gasket body portion 210a and the connecting portion 210b are an integrated structure, and there is no need to assemble the gasket body portion 210a and the connecting portion 210b, thereby saving time and cost.

[0060] Combination Figure 1 , Figure 3 and Figure 4 As shown, pad claws 23 are provided on opposite sides of the connection portion 210b along the width direction of the gasket body 210. The pad claws 23 include a pad claw body portion 231 and a claw portion 232 connected to the pad claw body portion 231. For example, the side of the pad claw body portion 231 close to the claw portion 232 is fixedly connected to the side of the claw portion 232 close to the pad claw 23 body. The claw portion 232 is located below the pad claw body portion 231. Along the direction from the gasket body portion 210a to the connection portion 210b, the orthographic projection of the pad claw body portion 231 overlaps with the orthographic projection of the gasket body 210, so as to avoid the pad claw body portion 231 from occupying too much extra space and ensure the compactness of the overall structure. When the hardware is assembled on the profile, the width of the horizontal gasket 21 or the vertical gasket 22 is prevented from being greater than the corresponding width of the slot in the profile, which is conducive to assembling the horizontal gasket 21 or the vertical gasket 22 on the profile. Combined with Fig.10 As shown, there is a gap 231b between the pad claw body 231 and the gasket body 210, and the shape of the gap 231b can be similar to a herringbone structure along the gasket body 210a pointing to the connecting portion 210b. The gap 231b can avoid the risk of tearing and burrs between the gasket body 210 and the pad claw 23 during the stamping and extrusion process; Fig.10 As shown; the cross-sectional shape of the claw portion 232 along the thickness direction of the gasket body 210 can be a triangle, and the vertex angle of the triangle is located on the side away from the pad claw body portion 231. It can be understood that the claw portion 232 can be a triangular prism structure, with the vertex angle (sharp end) of the triangular prism facing downward. When the hardware is assembled on the profile, it is beneficial for the sharp end of the claw portion 232 to directly contact the surface of the material. When the gasket fastener 3 subsequently locks the gasket 2 with the profile, the sharp end of the claw portion 232 can directly bite into the profile to achieve the purpose of one-way locking, thereby eliminating the need to open bolt holes on the corresponding profile and assembling the hardware and the profile together.

[0061] Reference Fig.10 As shown, there is an angle α between the gasket body 210 and the claw portion 232, and the angle α can be an acute angle. When the hardware is assembled on the profile, if the angle of the acute angle is too large, the sum of the width of the pad claw 23 and the connecting portion 210b along the direction from the pad claw 23 to the connecting portion 210b is greater than the width of the gasket body 210a, which exceeds the size design of the horizontal gasket 21 and / or the vertical gasket 22 along the direction from the pad claw 23 to the connecting portion 210b. If the angle of the acute angle is too small, it is not conducive to the sharp end of the claw portion 232 biting into the profile, and the one-way The purpose of self-locking; optionally, in the present embodiment, the acute angle range can be 70°-80°, which is conducive to abutting the claw portion 232 against the surface of the profile in the later stage. When the gasket fastener 3 subsequently locks the gasket 2 and the profile, the sharp end of the claw portion 232 can directly bite into the profile to achieve the purpose of one-way locking, thereby preventing the profile and the hardware 100 from loosening, thereby avoiding the enlargement of the profile splicing gap and the looseness, and can also meet the size requirements of the horizontal gasket 21 and / or the vertical gasket 22 along the direction from the gasket claw 23 to the connecting portion 210b.

[0062] It should be noted that the gasket body 210 and the pad claw 23 can be an integrated structure, which reduces the assembly time between the gasket body 210 and the pad claw 23. When the hardware 100 is assembled on the profile, the assembly efficiency between the hardware 100 and the profile can also be improved. Of course, due to the differences in the structures of different profiles, a split structure can also be adopted between the gasket body 210 and the pad claw 23. The gasket body 210 and the pad claw 23 are designed according to actual conditions, and this embodiment does not make specific limitations.

[0063] Continue to refer to Figure 1 , Figure 3 , Figure 4 As shown, a connector 24 is provided on the side of the gasket body 210a away from the connecting portion 210b. The shape of the connector 24 is arc-shaped. When the hardware is assembled on the profile, the connector 24 can ensure that the gasket body 210 is locked, which not only prevents the gasket body 210 from rotating and deviating, but also has a guiding effect when the hardware 100 is installed on site, such as the pad claw 23 faces the side of the 45-degree angle joint of the profile, and the connector 24 is away from the side of the 45-degree angle joint of the profile, thereby speeding up the assembly efficiency of the profile and the hardware 100. The side of the connector 24 away from the gasket body 210 may not contact the horizontal support arm 11 and / or the vertical support arm 13. Of course, according to actual conditions, the side of the connector 24 away from the gasket body 210 may also contact the horizontal support arm 11 and / or the vertical support arm 13, which is not specifically limited in this embodiment.

[0064] Optionally, continue to refer to Fig.10As shown, a gasket through hole 210c is provided on the gasket body 210, and the gasket through hole 210c penetrates along the thickness direction of the gasket body 210, and the gasket through hole 210c is located at the junction between the gasket body part 210a and the connecting part 210b, and an arm through hole 110 is provided on the horizontal arm 11 and / or the vertical arm 13, and the arm through hole 110 penetrates along the thickness direction of the horizontal arm 11 and / or the vertical arm 13, and the arm through hole 110 corresponds to the gasket through hole 210c; the gasket fastener 3 sequentially connects the horizontal gasket 21 with the horizontal arm 11 and the vertical gasket 22 with the vertical arm 13 through the gasket through hole 210c and the arm through hole 110. The number of the arm through holes 110 can be the same as the number of the gasket through holes 210c, or the number of the arm through holes 110 can also be inconsistent with the number of the gasket through holes 210c, which is not specifically limited in this embodiment.

[0065] Continue to refer to Fig.12 As shown, the gasket fastener 3 includes a nut 31 and a screw rod 32 connected to the nut 31. The nut 31 has an inclined surface 310 on the side away from the screw rod 32. The inclined surface 310 of the nut 31 is inclined from the side away from the pad claw 23 to the side close to the pad claw 23. Self-locking is formed between the inclined surface 310 of the nut 31 and the screw rod 32. Along the thickness direction of the gasket body 210, the height of the nut 31 on the side close to the pad claw 23 is less than the height of the nut 31 on the side away from the pad claw 23. When the hardware is assembled on the profile, the pad claw 23 bites the surface of the profile, and the inclined surface 310 of the nut 31 can pressurize the inclined surface of the claw portion 232 of the pad claw 23, lock it in the splicing direction of 45 degrees and ensure that the splicing seam is tight. It can be understood that: the pad claw 23 bites the surface of the profile, and the inclined surface 310 of the nut 31 competes with the inclined surface of the splicing angle direction of the pad claw 23, thereby achieving the purpose of one-way locking.

[0066] Optionally, continue to refer to Fig.10 As shown, a pad claw groove 231a is provided on the pad claw body part 231 close to the gasket body part 210a and away from the connecting part 210b. The pad claw groove 231a is recessed toward the connecting part 210b. The cross-sectional shape of the pad claw groove 231a along the thickness direction of the pad claw 23 body is arc-shaped. The pad claw groove 231a can also avoid the risk of tearing and burrs on the gasket body 210 and the pad claw 23 during the stamping, blanking and extrusion process.
