Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of roller blinds, in particular to a roller blind bracket structure. Background Art
[0002] Curtains are common furniture, often installed along the edges of windows to block light. In the summer, due to the intense sunlight, some windows may require two layers of curtains. This is where patented products like those in publication number CN102996056 come in handy. The adjuster and bearing mounting holes on the roller bracket allow for simultaneous adaptation of two roller shafts. This means a single roller bracket is sufficient for two layers of curtains, reducing production costs and simplifying installation.
[0003] However, the roller shutter bracket of the above solution needs to be provided with an adjuster mounting plate and a bearing mounting plate respectively, so that the adjuster mounting hole and the bearing mounting hole can adapt to the two roller shutter shafts respectively, which results in a larger size of the roller shutter bracket and occupies the space around the window. Utility Model Content
[0004] The utility model aims to solve the problem in the prior art that the roller shutter bracket is large in size and occupies space around the window.
[0005] In order to solve the above problems, the utility model provides a rolling shutter bracket structure, including a bracket main board and a first mounting plate and a second mounting plate both connected to the bracket main board, the bracket main board, the first mounting plate and the second mounting plate are perpendicular to each other, the bracket main board is provided with a first mounting hole and a second mounting hole, the spacing between the vertical projections of the first mounting hole and the second mounting hole on the first mounting plate is smaller than the diameter of the rolling shutter shaft, the spacing between the vertical projections of the first mounting hole and the second mounting hole on the second mounting plate is greater than the diameter of the rolling shutter shaft, a guide member is detachably connected to the bracket main board, the guide member is located between the first mounting plate and the second mounting plate, and the spacing between the vertical projection of the end of the guide member away from the second mounting hole on the first mounting plate and the vertical projection of the second mounting hole on the first mounting plate is greater than the radius of the rolling shutter shaft.
[0006] In the above solution, the first mounting hole and the second mounting hole are used to install the roller blind shaft, respectively, while the first mounting plate and the second mounting plate are used to selectively install on the wall. Compared with the prior art, the above solution is achieved by setting both the first mounting hole and the second mounting hole on the bracket main board. When the installation space is large, the first mounting plate is installed on the wall, and the second mounting plate is in a horizontal state. Since the spacing between the vertical projections of the first mounting hole and the second mounting hole on the second mounting plate is larger than the diameter of the roller blind shaft, the roller blind shafts of the first mounting hole and the second mounting hole are staggered in the horizontal direction, and the drooping pull cords of the two roller blind shafts will not interfere with each other. When the installation space is small, the second mounting plate is installed on the wall, and the first mounting plate is in a horizontal state. Since the spacing between the vertical projections of the first mounting hole and the second mounting hole on the first mounting plate is smaller than the diameter of the roller blind shaft, the roller blind shafts of the first mounting hole and the second mounting hole are staggered in the horizontal direction. diameter, that is, the rolling curtain shafts of the first mounting hole and the second mounting hole have overlapping areas in the horizontal direction, so the dimension of the bracket main board in the direction parallel to the first mounting piece can be made smaller, saving installation space. At the same time, considering that the drooping pull cords of the two rolling curtain shafts will interfere with each other, the above scheme further provides a guide member between the first mounting piece and the second mounting piece, and the distance between the guide member and the vertical projection of the second mounting hole on the first mounting piece is greater than the radius of the rolling curtain shaft, so that the pull cord of the rolling curtain shaft of the first mounting hole can be wound around the guide member and then drooped, so that the pull cords of the rolling curtain shafts of the first mounting hole and the second mounting hole are separated from each other in the horizontal direction to avoid interference.
[0007] In an improved solution, a wire groove is provided on the side of the guide member facing the first mounting hole, and a wire outlet is provided at the end of the wire groove away from the second mounting hole, so that the guide member can better guide the pull rope of the roller blind shaft of the first mounting hole through the wire groove.
[0008] In an improved solution, the bottom of the wire groove is in a convex arc shape or a convex cone shape, so that the pull cord of the roller blind shaft of the first mounting hole can move more smoothly in the wire groove.
[0009] In an improved solution, the bracket mainboard is provided with an assembly hole at a position corresponding to the guide member, and the guide member is provided with a fastening bolt that fits into the installation hole, so that the guide member can be conveniently disassembled and assembled relative to the bracket mainboard through the fastening bolt and the assembly hole.
[0010] In an improved solution, the first mounting hole and the second mounting hole are both cross-shaped through holes, and the first mounting hole and the second mounting hole as cross-shaped through holes can better adapt to the end of the roller blind shaft.
[0011] In an improved solution, a conversion member having a circular inner hole is further included, and the conversion member is used to be detachably embedded in the first mounting hole and / or the second mounting hole, so that by selectively embedding the conversion member in the first mounting hole and / or the second mounting hole, the first mounting hole and the second mounting hole, which were originally cross-shaped through holes, can be changed into the circular inner hole of the conversion member, thereby realizing the assembly of various types of roller blind shafts or other parts.
[0012] In an improved solution, a cross-shaped first insert is provided on one side of the outer peripheral wall of the conversion member and a cross-shaped second insert is provided on the other side, the first insert and the second insert are staggered with each other, and the first mounting hole and the second mounting hole can both be used for the first insert to pass through, so that by passing the first insert through the first mounting hole or the second mounting hole and then rotating the conversion member, the first insert and the second insert can be respectively engaged with the two sides of the first mounting hole or the second mounting hole of the bracket mainboard, thereby realizing the engagement and fixation of the conversion member relative to the first mounting hole or the second mounting hole.
[0013] In an improved solution, the bracket mainboard is roughly rectangular, and the first mounting piece and the second mounting piece are respectively located on both sides of any corner of the bracket mainboard, so that the layout is more reasonable. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0025] See also Figure 1-Figure 5 , an embodiment of the present invention provides a rolling curtain bracket structure, including a bracket main board 1 and a first mounting piece 2 and a second mounting piece 3 both connected to the bracket main board 1, the bracket main board 1, the first mounting piece 2 and the second mounting piece 3 are perpendicular to each other, the bracket main board 1 is provided with a first mounting hole 11 and a second mounting hole 12, the spacing between the vertical projections of the first mounting hole 11 and the second mounting hole 12 on the first mounting piece 2 is smaller than the diameter of the rolling curtain shaft, the spacing between the vertical projections of the first mounting hole 11 and the second mounting hole 12 on the second mounting piece 3 is greater than the diameter of the rolling curtain shaft, and a guide member 4 is detachably connected to the bracket main board 1, the guide member 4 is located between the first mounting piece 2 and the second mounting piece 3, and the spacing between the vertical projection of the end of the guide member 4 away from the second mounting hole 12 on the first mounting piece 2 and the vertical projection of the second mounting hole 12 on the first mounting piece 2 is greater than the radius of the rolling curtain shaft.
[0026] like Figure 1As shown, in this embodiment, the bracket mainboard 1 is roughly rectangular. It should be noted that the above "the bracket mainboard 1 is roughly rectangular" also includes an ellipse or other polygonal shapes similar to a rectangle. The first mounting piece 2 and the second mounting piece 3 are respectively located on both sides of any corner of the bracket mainboard 1, so that the layout is more reasonable. Figure 1 As a reference, the first mounting piece 2 is located on the upper side of the bracket main board 1, the second mounting piece 3 is located on the left side of the bracket main board 1, the first mounting hole 11 is located in the upper right area of the bracket main board 1, and the second mounting hole is located in the lower area of the bracket main board 1. In addition, under normal circumstances, two bracket main boards 1 need to be used simultaneously, and the roller blind shaft is installed between the two bracket main boards 1.
[0027] In addition, due to the uncertainty of the aperture size, the spacing of the vertical projections of the first mounting hole 11 and the second mounting hole 12 on the first mounting piece 2 referred to in the embodiment refers to the spacing of the vertical projections of the center of the first mounting hole 11 and the center of the second mounting hole 12 on the first mounting piece 2, the spacing of the vertical projections of the first mounting hole 11 and the second mounting hole 12 on the second mounting piece 3 refers to the spacing of the vertical projections of the center of the first mounting hole 11 and the center of the second mounting hole 12 on the second mounting piece 3, and the spacing of the vertical projection of the end of the guide member 4 away from the second mounting hole 12 on the first mounting piece 2 relative to the vertical projection of the second mounting hole 12 on the first mounting piece 2 refers to the spacing of the vertical projection of the end of the guide member 4 away from the second mounting hole 12 on the first mounting piece 2 relative to the vertical projection of the second mounting hole 12 on the first mounting piece 2.
[0028] In the above solution, the first mounting hole 11 and the second mounting hole 12 are used to install the roller blind shaft, and the first mounting piece 2 and the second mounting piece 3 are used to selectively install on the wall. Of course, the installation of the first mounting piece 2 and the second mounting piece 3 relative to the wall belongs to the existing technology and will not be described in detail. In actual use, when the installation space is large, such as Figure 2 As shown, the first mounting plate 2 is mounted to the wall, and the second mounting plate 3 is in a horizontal state. Since the distance between the vertical projections of the first mounting hole 11 and the second mounting hole 12 on the second mounting plate 3 is greater than the diameter of the rolling curtain shaft, the rolling curtain shafts of the first mounting hole 11 and the second mounting hole 12 are staggered in the horizontal direction, and the drooping pull cords of the two rolling curtain shafts will not interfere with each other. In this case, the guide member 4 does not need to be provided;
[0029] When the installation space is small, such as Figure 1As shown, the second mounting piece 3 is mounted to the wall, and the first mounting piece 2 is in a horizontal state. Since the spacing between the vertical projections of the first mounting hole 11 and the second mounting hole 12 on the first mounting piece 2 is smaller than the diameter of the rolling curtain shaft, that is, the rolling curtain shafts of the first mounting hole 11 and the second mounting hole 12 have overlapping areas in the horizontal direction, the dimension of the bracket main board 1 in the direction parallel to the first mounting piece 2 can be made smaller, saving the horizontal installation space. At the same time, considering that the drooping pull cords of the two rolling curtain shafts will interfere with each other, the above scheme further provides a guide member 4 between the first mounting piece 2 and the second mounting piece 3, and the spacing between the vertical projections of the guide member 4 and the second mounting hole 12 on the first mounting piece 2 is larger than the radius of the rolling curtain shaft, so that the pull cord of the rolling curtain shaft of the first mounting hole 11 can be wound around the guide member 4 to the right and then droop, so that the pull cords of the rolling curtain shafts of the first mounting hole 11 and the second mounting hole 12 are separated from each other in the horizontal direction to avoid interference.
[0030] As an improvement to the guide member 4, a wire groove 41 is provided on the side of the guide member 4 facing the first mounting hole 11. A wire outlet 42 is provided at the end of the wire groove 41 away from the second mounting hole 12. Thus, the guide member 4 can better guide the pull cord of the roller blind shaft of the first mounting hole 11 through the wire groove 41. Furthermore, the bottom of the wire groove 41 is convexly arc-shaped or convexly conical, so that the pull cord of the roller blind shaft of the first mounting hole 11 can move more smoothly within the wire groove 41.
[0031] In this embodiment, the bracket mainboard 1 has an assembly hole 13 at a position corresponding to the guide member 4. The guide member 4 is provided with a fastening bolt 43 that engages with the assembly hole. This facilitates assembly and removal of the guide member 4 from the bracket mainboard 1 through the fastening bolt 43 and the assembly hole 13. The assembly hole 13 is preferably a screw hole, and the fastening bolt 43 is preferably a bolt, which facilitates installation and provides good stability. Alternatively, a removable connection between the guide member 4 and the bracket mainboard 1 can be achieved by providing a slot on the bracket mainboard 1 for the guide member 4 to engage.
[0032] In this embodiment, the first mounting hole 11 and the second mounting hole 12 are both cross-shaped through holes. The cross-shaped first mounting hole 11 and the second mounting hole 12 can better adapt to the end of the roller blind shaft. In the improved solution, a conversion member 5 having a circular inner hole 51 is further included. The conversion member 5 is used to be removably engaged with the first mounting hole 11 and / or the second mounting hole 12. Therefore, by selectively engaging the conversion member 5 with the first mounting hole 11 and / or the second mounting hole 12, the first mounting hole 11 and the second mounting hole 12, which were originally cross-shaped through holes, can be converted into the circular inner hole 51 of the conversion member 5, thereby accommodating the assembly of various types of roller blind shafts or other parts.
[0033] More specifically, in this embodiment, a cross-shaped first insert 52 is provided on one side of the outer peripheral wall of the conversion member 5 and a cross-shaped second insert 53 is provided on the other side. The first insert 52 and the second insert 53 are staggered with each other, and the first mounting hole 11 and the second mounting hole 12 can both be used for the first insert 52 to pass through. Therefore, by passing the first insert 52 through the first mounting hole 11 or the second mounting hole 12 and then rotating the conversion member 5, the first insert 52 and the second insert 53 can be respectively engaged with the two sides of the first mounting hole 11 or the second mounting hole 12 of the bracket main board 1, thereby realizing the embedding and fixing of the conversion member 5 relative to the first mounting hole 11 or the second mounting hole 12.
