Technical Field

[0001] The utility model relates to the technical field of garage doors, in particular to a door panel connecting mechanism and a garage door comprising the same. Background Art

[0002] Currently, the multiple door panels in existing garage doors are mostly connected by side connections, specifically using iron or plastic parts with a thickness of 1.5-2.5mm. After prolonged operation, the door mechanism can deform and even break, causing unnecessary property damage and, in worse cases, personal injury due to door panel detachment, seriously affecting user experience and comfort. Furthermore, the existing iron connection mechanism, due to the iron-to-iron connection, can generate noise over time, resulting in a poor customer experience.

[0003] Based on this, the present application provides a new door panel connection mechanism and a garage door including the same, which can solve the problems of the existing garage door door panel connection mechanism, such as short service life, high noise, and difficult and expensive maintenance.

[0004] The technical problem to be solved by the utility model is to provide a door panel connecting mechanism, which can be assembled simply and conveniently, ensures that the door panel runs smoothly and quickly, and has an excellent quiet effect, thereby overcoming the shortcomings of the existing door panel connecting mechanism.

[0005] In order to solve the above technical problems, the present invention provides a door panel connection mechanism, wherein the door panel includes a plurality of door pieces, and the door panel connection mechanism includes a fixing member and a positioning pin shaft.

[0006] The fixing piece adopts a long strip structure with a stepped protrusion at one end, and both ends of the long strip structure are arc-shaped ends. A fixing hole for fixedly connecting to the side of each door leaf is provided at the center of the long strip structure, and a first positioning hole is provided on the stepped protrusion of the long strip structure, and a second positioning hole is provided at the other end of the long strip structure. The second positioning hole includes a circular hole and an oblong hole radially extending from the circular hole along the length direction of the fixing piece;

[0007] The positioning pin shaft has a positioning portion on its circumferential surface, and the positioning portion is the periphery of the cross-section that matches the oblong hole. When the two adjacent fixing members are stacked end to end, the positioning pin shaft passes through the circular holes of the first positioning hole and the second positioning hole, so that the positioning portion of the positioning pin shaft is stuck in the oblong hole of the second positioning hole, thereby realizing the connection and positioning of the two adjacent fixing members.

[0008] A further improvement includes a self-lubricating silent sleeve, the sleeve of which is arranged between the first positioning hole and the positioning pin shaft.

[0009] As a further improvement, one end of the sleeve of the self-lubricating silent bushing is provided with a convex edge extending outward, and the convex edge is arranged at the end where the two adjacent fixing members overlap.

[0010] As a further improvement, the fixing part is made of high-hardness aluminum alloy, the positioning pin is made of high-hardness steel, and the self-lubricating silent sleeve is made of copper.

[0011] As a further improvement, the fixing piece is made of 6mm thick high-hardness aluminum alloy.

[0012] Further improvements include an anti-wear isolation member, which includes an isolation plate and a fixed gasket vertically arranged on the isolation plate. The fixed gasket is used to be arranged between the door sheet and the fixing member, and the fixed gasket is provided with an installation hole corresponding to the fixing hole. The length of the isolation plate is the same as the length of the door sheet, and the isolation plate is fixed to the outer side of the door sheet to achieve isolation between the inner door sheet and the outer door sheet when the door panel is rolled up.

[0013] As a further improvement, the fixing gasket is arranged along the length of the isolation plate, and both end surfaces of the fixing gasket are provided with avoidance semicircular holes for the positioning pin shaft to pass through.

[0014] As a further improvement, the anti-wear isolation piece is made of plastic.

[0015] As a further improvement, the fixing hole adopts a countersunk structure.

[0016] As another improvement of the present invention, the present invention further includes a garage door, which includes a rolling door panel composed of a plurality of door slices, and the above-mentioned door panel connection mechanism is respectively provided on both sides of the rolling door panel.

[0017] After adopting such a design, the utility model has at least the following advantages:

[0018] 1. The door panel connection mechanism of the utility model can meet the connection and positioning requirements when two fixing parts are connected end to end through the provision of the oblate hole in the fixing part and the provision of the positioning part in the positioning pin shaft. It has a clever structure, is easy to process, is conducive to assembly, and can also avoid the problem of easy assembly errors.

[0019] 2. The self-lubricating silent bushing is also set to avoid the noise generated by the relative movement between the fixing parts and the positioning pin shaft when the door panel is running, thereby improving the user experience.

[0020] 3. The fixings are made of high-hardness aluminum alloy and the positioning pins are made of high-hardness steel, which greatly improves the force strength of the connection mechanism and has a solid structure. It can avoid the risk of breakage of the door panel connection mechanism, improve safety, and thus avoid a series of property losses and after-sales costs.

[0021] 4. The anti-wear spacer isolates the inner and outer panels of the garage door when rolled up, preventing contact and friction. This prevents friction damage to the surface of existing rolling shutter panels, which can affect performance. The plastic anti-wear spacer prevents direct contact between the side of the door panel and the metal fixings, thus eliminating noise caused by metal-to-metal friction and achieving excellent noise reduction.

[0030] The following describes exemplary embodiments of the present invention in more detail with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. Rather, these embodiments are provided to enable a more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0031] Refer to the attached Figures 1 to 3 As shown in FIG, the door panel connecting mechanism of this embodiment is used for a door panel 10 connected in sequence by a plurality of door sheets 20. The door panel connecting mechanism includes a fixing member 1 and a positioning pin shaft 2.

[0032] Combined with attachment Figure 4 As shown, the fixing member 1 is an elongated structure with a stepped protrusion 11 at one end. Both ends of the elongated structure are curved, allowing for rotation between two adjacent fixing members 1. A fixing hole 12 is provided at the center of the elongated structure for secure connection to the side of each door panel 20. The fixing hole 12 is a countersunk structure. A first positioning hole 13 is provided on the stepped protrusion 11 of the elongated structure, and a second positioning hole 14 is provided at the other end of the elongated structure. The second positioning hole 14 comprises a circular hole 141 and an oblong hole 142 extending radially from the circular hole 141 along the length of the fixing member 1.

[0033] Combined with attachment Figure 5 As shown, the circumferential surface of the positioning pin 2 is provided with a positioning portion 21. The positioning portion 21 is a section periphery that matches the oblong hole 142. For example, two planes are milled out on two opposite surfaces of the pin to fit in with the two opposite planes of the oblong hole 142, thereby achieving follow-up movement between the two fixing members 1 and the two opposite door panels 20. When the door panel connection mechanism is assembled, the two adjacent fixing members 1 are stacked end to end. After the positioning pin 2 passes through the circular holes 141 of the first positioning hole 13 and the second positioning hole 14, the positioning portion 21 of the positioning pin 2 is snapped into the oblong hole 142 of the second positioning hole 14, thereby achieving connection and positioning of the two adjacent fixing members 1, completing the assembly of the two fixing members. In this way, all fixing members are connected end to end.

[0034] A preferred embodiment further includes a self-lubricating silent sleeve 3. Figure 6 As shown, the sleeve 31 of the self-lubricating silent sleeve 3 is arranged between the first positioning hole 13 and the positioning pin 2. One end of the sleeve 31 of the self-lubricating silent sleeve 3 is provided with a convex edge 32 extending outward, and the convex edge 32 is arranged at the end of the two adjacent fixing members 1. Figure 3 shown.

[0035] Furthermore, in this embodiment, the fixing member 1 is made of a high-hardness aluminum alloy, such as a 6mm thick high-hardness aluminum alloy; the positioning pin 2 is made of high-hardness steel, and the self-lubricating silent bushing 3 is made of copper. Because the self-lubricating silent bushing 3 is made of a softer material than the fixing member 1 and positioning pin 2, it effectively prevents direct contact between the two connected fixing members 1 and also prevents direct contact between the first positioning hole 13 and the positioning pin 2. This significantly reduces the sound of friction between the hard metals, reduces noise generation, and achieves an excellent silencing effect.

[0036] A more preferred embodiment further includes an anti-wear isolation member 4. Figure 7 As shown, the anti-wear isolation member 4 includes an isolation plate 41 and a fixing washer 42 perpendicularly mounted on the isolation plate 41. The fixing washer 42 is positioned between the door panel 20 and the fixing member 1. The fixing washer 42 is provided with a mounting hole 421 corresponding to the fixing hole 12. After the fixing bolt passes through the fixing hole 12 on the fixing member 1 and then through the mounting hole 421, it is fixedly connected to the mounting groove on the side of the door panel, thereby securing the door panel connection mechanism to the door panel 10. The isolation plate 41 is the same length as the door panel 20 and is fixed to the outer side of the door panel 20. This ensures that when the door panel 10 is rolled up, the isolation plate 41 does not affect the inward rolling of the door panel 10. Furthermore, the isolation plate 41 maintains a certain distance between the inner and outer layers of the rolled-up door panel 10, effectively preventing contact friction between the inner and outer layers, reducing wear on the door panel 20 and extending its service life.

[0037] Furthermore, the fixing gasket 42 is provided along the length of the isolation plate 41. Semicircular holes 422 are provided on both end surfaces of the fixing gasket 42 for the positioning pin 2 to pass through, so as not to affect the rotation of the positioning pin 2. Furthermore, to ensure a tight fit between the isolation plate 41 and the door panel 20, the surface of the isolation plate 41 that contacts the door panel 20 is configured to match the surface of the door panel 20, such as a concave-convex surface.

[0038] More preferably, the anti-wear isolating member 4 is made of plastic material, so that the anti-wear isolating member 4 can effectively prevent the sound of metal friction between the door panel 20 and the fixing member 1, and the noise reduction effect is better.

[0039] When the above-mentioned door panel connecting mechanism is used for a garage door using a rolling door panel, the above-mentioned door panel connecting mechanism is respectively provided on both sides of the rolling door panel, which can not only meet the connection requirements of multiple door pieces 20, but also meet the requirements of safety, reliability, low noise and long service life during the opening and closing operation of the door panel 10.

[0040] This utility model improves upon the traditional garage door panel connection mechanism, radically reshaping the existing structure. It addresses issues such as noise, breakage after prolonged use, surface wear, and noise caused by movement when the panel connection mechanism connects to the door panel. The utility model features a simple structure, ease of manufacture, low friction, low noise, and smooth operation.

[0041] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Those skilled in the art can make some simple modifications, equivalent changes or modifications based on the technical content disclosed above, which fall within the scope of protection of the present invention.
