Description

[Technical Field]

[0001] This invention demonstrates a connection mechanism that facilitates the assembly and disassembly of sheet metal, belonging to the technical field of sheet metal connection mechanisms. [Background Technology]

[0002] Wood-plastic composite materials have been widely used in outdoor panels, wall panels, walls, and decorative panels. Currently, the installation of wood-plastic panels usually uses a keel frame as a foundation, and fasteners are installed on the keel frame to lay the panels on the keel. For example, Chinese invention patent (CN104675074B) discloses a panel connector, including a connector body and a tenon groove. The tenon groove has a first buckle and a second buckle with opposite engagement directions. The first buckle and the second buckle each have an elastic support part and an elastic buckle frame part integrally connected to the elastic support part. The connector enters the receiving groove through the elastic deformation of the elastic support part and the elastic buckle frame part to achieve the connection between the connector and the panel. However, if the force is too great when the connector is connected to the panel, the first buckle and the second buckle may break, thereby damaging the connector. In addition, the connector cannot be easily removed after being connected to the panel, which affects the subsequent maintenance and replacement of the panel. [Summary of the Invention]

[0003] The purpose of this invention is to solve the problem of easy damage to the connecting mechanism. To this end, a connecting mechanism that facilitates the disassembly and assembly of sheet metal is provided, which can reduce the possibility of damage to the connecting mechanism.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] A connecting mechanism for easy assembly and disassembly of sheet metal is provided. The connecting mechanism is installed on a keel frame and has at least two fasteners for connecting the sheet metal. The sheet metal has a slot for engaging with the fasteners. The connecting mechanism has an elastic element for changing the distance between two adjacent fasteners. The fastening directions of the two adjacent fasteners are opposite to those of the sheet metal. The elastic element achieves elastic deformation through the action of the sheet metal on the fasteners. The fasteners are inserted into or disengaged from the slots through the elastic deformation of the elastic element.

[0006] The beneficial effects of using the present invention are:

[0007] The connecting mechanism described in this invention includes an elastic element. When the plate is connected to the connecting mechanism, pressing the plate causes the elastic element to elastically deform, thereby changing the distance between the two fastening elements and allowing the fastening elements to be smoothly inserted into the plate. When the fastening elements lose the force from the plate, the elastic element returns to its original shape, causing the two fastening elements to return to their original positions, thus achieving the fastening of the plate. When it is necessary to remove the plate, an external force along the length of the connecting mechanism is applied to the plate. The plate acts on the fastening elements, causing the elastic element to elastically deform, thereby changing the distance between the two fastening elements and allowing the fastening elements to be smoothly inserted into the plate. This invention allows for the detachment of the sheet metal. During installation, the fasteners are not forcibly inserted, preventing excessive deformation and protecting both the fasteners and the sheet metal, thus extending their lifespan. Furthermore, during removal, the elastic deformation of the elastic element alters the gap in the fasteners, facilitating their smooth detachment. This invention makes sheet metal installation and removal more convenient and simpler, effectively improving installation and removal efficiency.

[0008] Preferably, the connecting mechanism has an installation gap for mounting the elastic element, which undergoes elastic deformation due to changes in the width of the installation gap. Using the aforementioned technical solution, the installation gap provides space for variations in the distance between the two fastening elements, making distance changes between the fastening elements less strenuous and reducing the possibility of excessive deformation of the fastening elements.

[0009] Preferably, the elastic element has an opening, and its two ends are respectively connected to the side walls on both sides of the installation gap; and / or, the elastic element is a closed ring, and the elastic element is located within the installation gap. Using the aforementioned technical solution, the elastic element is connected to or located within the installation gap. The force exerted by the plate on the fastener is directly applied to the elastic element through the installation gap, making the elastic element more prone to deformation, reducing the force required by the plate on the fastener, and thus reducing the external force on the fastener. This protects both the fastener and the plate, and improves their service life.

[0010] Preferably, the connecting mechanism includes a limiting spring, which undergoes elastic deformation after the fastening member and the plate are fastened together. Using the aforementioned technical solution, when the plate and the fastening member are in the fastened state, the limiting spring is in close contact with the bottom of the plate and exerts an upward force on the plate, while the fastening member exerts a downward limiting force on the plate. Under the action of the limiting spring, the plate and the fastening member can remain in close contact, reducing the swaying amplitude of the plate, improving the connection stability between the plate and the connecting mechanism, and also improving the user experience.

[0011] Preferably, the connecting mechanism is provided with a clearance notch to allow the limiting spring to deform elastically. Using the aforementioned technical solution, the clearance notch provides space for the limiting spring to deform, allowing it to generate a larger deformation. This facilitates the separation of the sheet metal from the fastener during disassembly, further improving the disassembly efficiency of the sheet metal.

[0012] Preferably, the limiting spring includes a connecting part and a deformable part. The connecting part is fixedly connected to the connecting mechanism, and the deformable part is inclined and exposed in the clearance notch.

[0013] Preferably, the limiting spring includes a pressing part and a resetting part, the resetting part being confined between the connecting mechanism and the pressing part, and the pressing part being exposed in the clearance notch under the action of the resetting part.

[0014] Preferably, the connecting mechanism includes at least two limiting springs, with the limiting springs positioned between two fastening members and / or the fastening members positioned between the two limiting springs.

[0015] Preferably, the slot includes a locking part that engages with the fastener and an unlocking part for disengaging the fastener. The fastener is unlocked by moving from the locking part to the unlocking part due to the elastic deformation of the elastic element. Using the aforementioned technical solution, during installation, the elastic deformation of the elastic element changes the distance between the fasteners, allowing the fasteners to be inserted into the unlocking part of the slot. After the external force is removed, the fastener moves to the locking part under the action of the elastic element, thus achieving engagement between the fastener and the plate. During disassembly, external force causes the elastic element to deform, moving the fastener from the locking part to the unlocking part, allowing the fastener to disengage from the slot and achieving disassembly of the plate.

[0016] Preferably, the fastening element includes a hook for fastening the plate, and the hooks of the two fastening elements are arranged opposite or back to back.

[0041] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0042] like Figures 1 to 13As shown in the figure, this embodiment demonstrates a connecting mechanism 1 that facilitates the assembly and disassembly of the sheet metal 3. The connecting mechanism 1 is installed on the keel frame 2. The connecting mechanism 1 is provided with at least two fastening members 12 for connecting the sheet metal 3. The connecting mechanism 1 is provided with an elastic member 11 for changing the distance between two adjacent fastening members 12. The elastic member 11 achieves elastic deformation by acting on the fastening members 12 through the sheet metal 3.

[0043] like Figure 1 and Figure 2 As shown, in this embodiment, the connecting mechanism 1 is provided with an installation gap 14 for installing the elastic element 11. The elastic element 11 generates elastic deformation by changing the width of the installation gap 14. The installation gap 14 provides space for the change of the distance between the two fastening elements 12, making the distance change of the fastening elements 12 less effort and reducing the possibility of excessive deformation of the fastening elements 12.

[0044] In this embodiment, the connecting mechanism 1 is provided with an elastic element 11. When the plate 3 is connected to the connecting mechanism 1, pressing the plate 3 causes the elastic element 11 to undergo elastic deformation, thereby changing the distance between the two fastening elements 12, allowing the fastening elements 12 to be smoothly inserted into the plate 3. When the fastening elements 12 lose the force of the plate 3, the elastic element 11 returns to its original shape, thereby returning the two fastening elements 12 to their original positions, achieving the fastening of the plate 3. When it is necessary to remove the plate 3, an external force along the length direction of the connecting mechanism 1 is applied to the plate 3. The plate 3 acts on the fastening elements 12, causing the elastic element 11 to undergo elastic deformation, thereby changing the distance between the two fastening elements 12, allowing the fastening elements 12 to be easily inserted into the plate 3. The fastener 12 can smoothly detach from the plate 3, thus enabling the disassembly of the plate 3. In this embodiment, the fastener 12 is not completely forcibly inserted during the installation process of the plate 3, so that the fastener 12 will not undergo excessive deformation. This can protect both the fastener 12 and the plate 3, making them less prone to damage and improving their service life. In addition, when the plate 3 is removed, the elastic deformation of the elastic member 11 can also change the gap of the fastener 12, thereby allowing the fastener 12 to detach smoothly from the plate 3. This embodiment makes the installation and disassembly of the plate 3 more convenient and simpler, and can effectively improve the efficiency of the installation and disassembly of the plate 3.

[0045] like Figure 2As shown, in this embodiment, the elastic element 11 has an opening, and the overall shape of the elastic element 11 is C-shaped. Both ends of the elastic element 11 are connected to the side walls on both sides of the mounting gap 14. The elastic element 11 is connected to the mounting gap 14, and the force exerted by the plate 3 on the fastener 12 is directly applied to the elastic element 11 through the mounting gap 14. This makes the elastic element 11 more prone to deformation, reducing the force required by the plate 3 on the fastener 12, thereby reducing the external force on the fastener 12 and protecting both the fastener 12 and the plate 3, thus improving their service life. It is understood that in other embodiments, the elastic element 11 can also be a closed ring, with the elastic element 11 located within the mounting gap 14.

[0046] like Figure 2 As shown, in this embodiment, the long side of the connecting mechanism 1 is provided with two elastic members 11. The elastic members 11 are provided on the long side of the connecting mechanism 1 so that the elastic members 11 have sufficient deformation distance. Of course, it can be understood that in other embodiments, the number of elastic members 11 can also be one or more on each long side. Of course, it can also be understood that the connecting mechanism 1 can also be provided with only one elastic member 11.

[0047] like Figure 1 and 2 As shown, the connecting mechanism 1 in this embodiment includes a limiting spring 13. The limiting spring 13 undergoes elastic deformation after the fastening member 12 and the plate 3 are fastened together. When the plate 3 and the fastening member 12 are in the fastened state, the limiting spring 13 is in close contact with the bottom of the plate 3 and exerts an upward force on the plate 3. Meanwhile, the fastening member 12 exerts a downward limiting force on the plate 3 during the fastening process. Under the action of the limiting spring 13, the plate 3 and the fastening member 12 can be kept in close contact, reducing the shaking amplitude of the plate 3, improving the connection stability between the plate 3 and the connecting mechanism 1, and also improving the user experience.

[0048] like Figure 2As shown, in this embodiment, the connecting mechanism 1 is provided with a clearance notch 15 for the elastic deformation of the limiting spring 13. The clearance notch 15 provides space for the limiting spring 13 to deform, allowing the limiting spring 13 to generate a large deformation. This facilitates the disassembly of the plate 3 from the fastener 12 during disassembly, further improving the disassembly efficiency of the plate 3. In addition, the limiting spring 13 includes a connecting part 131 and a deformable part 132. The connecting part 131 is fixedly connected to the connecting mechanism 1, and the deformable part 132 is inclined and exposed in the clearance notch 15. In this embodiment, the connecting mechanism 1 is provided with two limiting springs 13 arranged in an inverted V-shape, and the two limiting springs 13 are located between the two fasteners 12. Of course, it can be understood that in other embodiments, the two limiting springs 13 may also be provided on both sides of the two fasteners 12; or at both ends of the connecting mechanism 1; or the two fasteners 12 may both have limiting springs 13 between them and on both sides of them.

[0049] Regarding the limiting spring 13, as well as... Figure 11 As shown, the plates 3 are usually spliced ​​at the ends during installation. During installation, the ends of two adjacent plates 3 are connected to some of the fasteners 12, so that the ends of the two plates 3 are respectively on both sides of the limiting spring 13. There is a gap between the two plates 3 to accommodate the limiting spring 13. In daily use, the installed plates 3 may shift due to thermal expansion and contraction or under the action of external force. In this embodiment, the limiting spring 13 is exposed in the avoidance notch 15 and can abut against the end of the plate 3, which can effectively limit the displacement of the plate 3, reduce the range of movement of the plate 3, make the plate 3 more flush and complete, reduce the phenomenon of large gaps or unevenness of the plate 3, and improve the aesthetics of the plate 3 after installation.

[0050] It should be noted that, in other embodiments, the limiting spring 13 may also include a pressing part and a resetting part. The resetting part is limited between the connecting mechanism 1 and the pressing part. The resetting part acts on the pressing part, causing the pressing part to be exposed vertically upward in the clearance notch 15. When the plate 1 is pressed down, the plate 1 acts on the pressing part, causing the pressing part to overcome the force of the resetting part and retract vertically downward in the clearance notch 15.

[0051] like Figures 6 to 11As shown, in this embodiment, the plate 3 is provided with a slot 31 for inserting the fastener 12. The slot 31 includes a locking part 311 that engages with the fastener 12 and an unlocking part 312 for disengaging the fastener 12. The fastener 12 is unlocked by moving from the locking part 311 to the unlocking part 312 through the elastic deformation of the elastic member 11. During the installation of the plate 3, the elastic deformation of the elastic member 11 changes the distance between the fasteners 12, allowing the fastener 12 to be inserted into the unlocking part 312 of the slot 31. After the fastener 12 loses external force, it moves to the locking part 311 under the action of the elastic member 11, thus achieving the fastening of the fastener 12 and the plate 3. During the disassembly of the plate 3, the elastic member 11 is deformed by external force, and the fastener 12 moves from the locking part 311 to the unlocking part 312 of the slot 31, thus disengaging the fastener 12 from the slot 31 and achieving the disassembly of the plate 3.

[0052] like Figure 3 and Figure 4 As shown, in this embodiment, the two fastening components 12 have opposite fastening directions to the plate 3; additionally, the fastening component 12 includes a hook 121 for fastening the plate 3, such as... Figure 3 As shown, the hooks 121 of the two fastening parts 12 are arranged inwards, that is, opposite to each other; as Figure 4 As shown, the hooks 121 of the two fastening members 12 can also be arranged outwards, i.e., opposite to each other. It should be noted that the structure of the fastening member 12 is not limited to the hook shown in the figure. In other embodiments, the fastening member 12 can also adopt an umbrella-shaped hook or a positioning groove, etc., which can be engaged or fastened with the plate 3. Alternatively, the fastening member 12 can be positioned with the plate 3 by interference fit or by limiting. Similarly, the structures of the two fastening members 12 can also be different.

[0053] like Figure 5As shown, in this embodiment, the connecting mechanism 1 is fixed to the keel frame 2. The keel frame 2 is provided with a slide rail 21 for accommodating the connecting mechanism 1. The connecting mechanism 1 has protrusions 16 on both sides that slide with the slide rail 21. Both ends of the protrusions 16 are provided with guide slopes to facilitate insertion into the slide rail 21. The guide slopes can reduce the installation difficulty of the connecting mechanism 1. The connecting mechanism 1 is slidably connected to the slide rail 21 through the protrusions 16, which can confine the connecting mechanism 1 within the slide rail 21. At the same time, the connecting mechanism 1 is provided with mounting holes 17. The connecting mechanism 1 is fixed by fasteners 22 passing through the mounting holes 17. The fasteners 22 can be screws. The connecting mechanism 1 uses mechanical parts such as bolts, studs, or pins for connection. Additionally, several protrusions 18 are provided on both sides of the connecting mechanism 1 that contact the keel frame 2. These protrusions 18 are spaced apart along the length of the raised strip 16, and their surfaces are smooth curved surfaces. After the connecting mechanism 1 is installed into the slide rail 21, the protrusions 18 contact the sidewalls of the keel frame 2, effectively reducing the swaying amplitude of the connecting mechanism 1 in the width direction. Simultaneously, the spaced protrusions 18 effectively reduce the contact area between the connecting mechanism 1 and the sidewalls of the keel frame 2, thereby reducing the friction force experienced by the connecting mechanism 1 during sliding and making the sliding of the connecting mechanism 1 smoother. It is understood that in other embodiments, the connecting mechanism 1 can also be detachably connected to the keel frame 2 through rotation; or, the connecting mechanism 1 can be connected to the keel frame 2 through a snap-fit; or, the connecting mechanism 1 can be integrally injection molded with the keel frame 2.

[0054] The installation and disassembly process of the plate 3 in this embodiment is as follows:

[0055] It should be noted that in this embodiment, taking the hooks 121 arranged opposite each other as an example, when the plate 3 acts on the fastener 12 during the installation and disassembly process, the elastic element 11 will stretch, that is, the distance between the two fasteners 12 increases; while when the hooks 121 of the fasteners 12 are arranged opposite each other, the elastic element 11 of the plate 3 will be compressed during the installation and disassembly process, that is, the distance between the two fasteners 12 decreases.

[0056] like Figure 7 As shown, before installation, the distance between the two fastening parts 12 is less than the distance between the two unlocking parts 312. During installation, a downward force is applied to the top surface of the plate 3. The plate 3 acts on the fastening parts 12, causing the elastic element 11 to stretch, increasing the distance between the two fastening parts 12 until the fastening parts 12 can enter the unlocking part 312 of the slot 31. After the fastening parts 12 enter the unlocking part 312, the fastening parts 12 lose the force of the plate 3. Under the action of the elastic element 11, the distance between the two fastening parts 12 decreases, causing the fastening parts 12 to move from the unlocking part 312 to the locking part 311, thus achieving the fastening of the fastening parts 12 with the slot 31, and completing the installation of the plate 3. Figure 8 As shown. Figure 9As shown, when plate 3 needs to be disassembled, an external force along the length of the connecting mechanism 1 is applied to plate 3, thereby pushing the left fastener 12 to move to the left, causing the elastic member 11 to stretch and increase the distance between the two fasteners 12. At this time, the right fastener 12 moves from the locking part 311 to the unlocking part 312, and the slot 31 on the right side of plate 3 loses the restriction of the fastener 12. At this time, the right side of plate 3 is lifted under the action of the limiting spring 13, and the fastener 12 completely disengages from the slot 31. At the same time, one side of plate 3 is lifted up, as shown. Figure 10 As shown, this facilitates the removal of plate 3.

[0057] It should be noted that the plate 3 can also be installed in other ways, see reference. Figure 10 As shown, the installation process of plate 3 is the reverse of the disassembly process of plate 3. Plate 3 can be placed at an angle so that the fastener 12 on the left side of the connecting mechanism 1 is first inserted into the slot 31 on the left side of plate 3. Then, the user presses the right side of plate 3 so that the slot 31 on the right side acts on the fastener 12 on the right side, thereby causing the elastic member 11 to extend and the distance between the two fasteners 12 to increase until the fastener 12 on the right side is also inserted into the slot 31 on the right side. After both fasteners 12 are inserted into the slot 31, the distance between the two fasteners 12 is reduced under the action of the elastic member 11, so that the fastener 12 moves from the unlocking part 312 to the locking part 311, realizing the fastening of the fastener 12 and the slot 31, thus completing the installation of plate 3.

[0058] like Figure 12 and Figure 13 As shown, the plate 3 can be fixed during installation by two adjacent connecting mechanisms 1. Specifically, the slot 31 on the left side of the plate 3 is connected to the right fastening member 12 of one connecting mechanism 1, and the slot 31 on the right side of the plate 3 is connected to the left fastening member 12 of another connecting mechanism 1. When the plate 3 acts on the fastening member 12, the elastic members 11 of the two connecting mechanisms 1 deform, thereby changing the distance between the two connecting mechanisms 1, so that the fastening member 12 can be inserted into the slot 31. After the elastic member 11 returns to its original shape, it drives the fastening member 12 to move from the unlocking part 312 to the locking part 311, that is, the distance between the two connecting mechanisms 1 is restored, realizing the fastening member 12 and the slot 31, thus completing the installation of the plate 3. It should be noted that when the hooks 121 of the fastening parts 12 on the same connecting mechanism 1 are arranged opposite each other, when the plate 3 acts on the fastening parts 12, the elastic element 11 is stretched, and the distance between the two connecting mechanisms 1 decreases; while when the hooks 121 of the fastening parts 12 on the same connecting mechanism 1 are arranged opposite each other, when the plate 3 acts on the fastening parts 12, the elastic element 11 is compressed, and the distance between the two connecting mechanisms 1 increases. The plate 13 can be installed by pressing the plate 3 against the two fastening parts 12 simultaneously, as shown in the reference. Figure 12Alternatively, one fastener 12 can be inserted into the slot 31 first, and then the other side can be pressed to insert the fastener 12 on the other side into the slot 31. (See reference) Figure 13 .

[0059] like Figures 14 to 18 As shown, in another embodiment, the structures of the two fastening members 12 on the connecting mechanism 1 can be different. In this embodiment, one of the fastening members 12 is an inclined limiting plate 122, which is inclined toward the other fastening member 12. The limiting plate 122 forms an angle of less than 90 degrees with the connecting mechanism 1. Figure 18 As shown, in this embodiment, the plate 3 is provided with a slot 31. The side of the plate 3 away from the slot 31 is inclined and matches the limiting plate 122. When the plate 3 is laid on the keel frame 2, the side of the plate 3 can cover the keel frame 2, making it difficult for the user to see the keel frame 2 with the naked eye, further improving the aesthetics of the plate 3 after it is laid, and also reducing the possibility of coins or other objects falling.

[0060] When installing plate 3, first insert the left side of plate 3 between the limiting plate 122 and the connecting mechanism 1. Then, the user presses the right side of plate 3, causing the right side slot 31 to act on the right side fastener 12, thereby causing the elastic member 11 to extend and the distance between the fastener 12 and the limiting plate 122 to increase until the right side fastener 12 is also inserted into the right side slot 31. Under the action of the elastic member 11, the distance between the fasteners 12 decreases, causing the fastener 12 to move from the unlocking part 312 to the locking part 311. In this embodiment, the limiting plate 122 limits the side of plate 3, and the fastener 12 engages the slot 31, thereby realizing the connection of plate 3 connecting mechanism 1.

[0061] like Figure 16 and Figure 17 As shown, in this embodiment, only one elastic element 11 can be provided on one side of the connection structure 1. In this embodiment, the elastic element 11 is located between the mounting hole 17 and the limiting plate 122.

[0062] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Those skilled in the art should understand that the present invention includes, but is not limited to, the contents described in the accompanying drawings and the specific embodiments above. Any modifications that do not depart from the functional and structural principles of the present invention will be included within the scope of the claims.
