Abstract
Description
Technical Field
[0001] This utility model relates to the field of sheet metal technology, and more specifically to a splicable sheet metal unit and sheet metal assembly. Background Technology
[0002] Currently, interlocking panels are widely used in home, commercial and industrial fields, and are favored for their convenient installation without the need for glue or nails.
[0003] Traditional splicing methods for panels typically employ mortise and tenon joints or interlocking connections for quick assembly and secure fixation, as described in Chinese utility models CN203462694U and CN212295478U. However, panels spliced using these methods have a fixed length or width after assembly. Therefore, in actual installation, panels often need to be custom-made or cut to size according to the specific installation requirements. Furthermore, if a panel is damaged, multiple adjacent panels must be removed for replacement, increasing repair costs and time. Utility Model Content
[0004] In order to overcome at least one deficiency of the prior art, this utility model provides a splicable board unit and board assembly that can be adapted to different sizes of laying.
[0005] To achieve the above objectives, this utility model provides a splicable board unit, including a board unit body, a first hook portion and a second hook portion located on the same side of the board unit body. The board unit body has a first edge and a second edge opposite to each other; the first hook portion and the second hook portion are respectively disposed on the first edge and the second edge, and the first hook portion and the second hook portion are arranged in the same direction; wherein, the first hook portion and the second hook portion respectively include a first abutment portion and a second abutment portion, the width of the first abutment portion is smaller than the width of the second abutment portion, and the shortest distance between the first abutment portion and the board unit body is smaller than the shortest distance between the second abutment portion and the board unit body.
[0006] Optionally, the second hook also includes a stop connected to the second abutment, the angle between the stop and the second abutment being a right angle or an obtuse angle. When the angle is a right angle or an obtuse angle, the stop will not obstruct the movement of the first hook within the second hook, and the stop can also limit the displacement of the first hook. Therefore, if a piece of board is damaged, the first hook of that board unit can easily disengage from the second hook of the adjacent board unit. As for disassembling the second hook of that board, simply lifting another adjacent board will disengage the second hook, thus eliminating the need to disassemble the adjacent board.
[0007] When the included angle is obtuse, there is less resistance. When the included angle is right, the positioning is better.
[0008] Optionally, along the direction perpendicular to the main body of the plate unit, the projection of the stop portion onto the second abutment portion is either a straight line or no projection. When the angle between the stop portion and the second abutment portion is a right angle, the projection is a straight line; when it is an obtuse angle, there is no projection. One end of the first abutment portion remains structurally open, meaning that one end of the first abutment portion is not connected to any other structure.
[0009] Optionally, the first hook portion includes a first sidewall connected to the first abutment portion, the second hook portion includes a second sidewall connected to the second abutment portion, the height of the first sidewall is less than the height of the second sidewall, and the height of the stop portion is 1 / 4 to 1 / 2 of the height of the first sidewall.
[0010] Optionally, the first sidewall and the first abutment are connected by a first arc, and the second sidewall and the second abutment are connected by a second arc. The central angles corresponding to the first arc and the second arc may be the same or different. If they are different, it is preferable that the central angle corresponding to the first arc is greater than the central angle corresponding to the second arc. In this way, when the second sidewall limits the first hook, there can still be a gap between the first sidewall and the second sidewall, providing a deformation allowance for the plate after it is subjected to force.
[0011] Optionally, the ratio of the difference d between the width of the first abutment and the width of the second abutment to the length L of the main body of the plate unit is 0.001-0.1, that is, the range of d / L is 0.001-0.1, preferably 0.005-0.1.
[0012] Optionally, the ratio of the difference d between the width of the first abutment and the width of the second abutment to the width W of the main body of the plate unit is 0.01-0.1, that is, the range of d / W is 0.01-0.1.
[0013] Optionally, both the first and second abutting parts can be set as planes or mutually mating curved surfaces.
[0014] Optionally, the main body of the board unit also has a third edge and a fourth edge; a third hook and a fourth hook located on the same side of the main body of the board unit, the third hook and the fourth hook being respectively provided on the third edge and the fourth edge, the third hook and the fourth hook being arranged in the same direction; wherein, the third hook and the fourth hook respectively include a third abutment and a fourth abutment, the width of the third abutment is smaller than the width of the fourth abutment, and the shortest distance between the third abutment and the main body of the board unit is less than the shortest distance between the fourth abutment and the main body of the board unit.
[0015] This utility model also provides a sheet metal assembly, comprising: at least two splicable sheet metal units as described above spliced together, wherein a first abutting portion of one splicable sheet metal unit is slidably disposed within a second abutting portion of the other splicable sheet metal unit, so as to realize that the width of the sheet metal assembly is adjustable.
[0016] Optionally, the panel assembly also includes edge panel units, which include a fifth hook and a sixth hook arranged opposite to each other. The fifth hook or the sixth hook is slidably disposed within the second abutment of an adjacent splicable panel unit.
[0017] In summary, the splicable panel unit and panel assembly provided by this utility model can be widely used in flooring and other fields. Because the width of the first abutment part is smaller than the width of the second abutment part, and the shortest distance between the first abutment part and the main body of the panel unit is less than the shortest distance between the second abutment part and the main body of the panel unit, the first abutment part of one splicing unit in adjacent panels can be slidably disposed within the second abutment part of another splicable panel unit, thereby achieving adjustable width of the panel assembly to adapt to different installation environments.
