Description

Technical Field

[0001] This invention relates to a collection storage rack, and more particularly to a push-pull type painting storage device for precious calligraphy and painting cultural relics. Background Technology

[0002] The collection and display of calligraphy and paintings typically utilize specialized mobile shelving units. Existing technology, such as the Chinese invention patent ZL200610052543.3, "Mobile Calligraphy and Painting Storage Cabinet," discloses such a storage structure. It includes a frame containing multiple hanging frames for suspending calligraphy and paintings, and guide rails for moving the hanging frames. Multiple hanging rails are located at the top of the frame, connecting the hanging frames. Rollers are located at the bottom of the frame, and these rollers are connected to guide rails fixedly embedded in the floor. The storage cabinet rollers are connected to the floor guide rails, which are parallel to the track direction. The storage cabinet rollers are connected to an electric drive device, allowing for electric or manual operation.

[0003] However, the invention patent mentioned above has the following shortcomings: First, the use of a hanging rail, hanging wheels, and riding-style roller structure means that each painting or calligraphy cannot be hung individually, and it is still not convenient to remove the paintings or calligraphy. Second, the hanging frame is equipped with load-bearing rollers at the bottom, and the load-bearing roller guide rail is fixedly embedded in the ground. Since the roller guide rail is a one-piece structure design, the guide rail is long and is laid from top to bottom along the length or width of the storage room floor. The presence of the roller guide rail will seriously affect the safety of vehicles and pedestrians passing around the storage rack. During vehicle handling or pedestrian walking, it is easy to bump into the guide rail and cause it to tip over, which is not only unsightly but also makes it unsafe to use. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a push-pull painting storage device that is more aesthetically pleasing and safer than the existing technology.

[0005] The technical solution adopted by the present invention to solve the above-mentioned technical problem is: a push-pull type painting storage device, characterized in that: the storage device includes...

[0006] The painting mounting frame is vertically suspended below the top beam, and the painting mounting frame is equipped with a grid for fixing the calligraphy and painting;

[0007] A hanging rail assembly for connecting an artwork mounting frame and a top beam. The hanging rail assembly includes a hanging rail connecting plate fixed to the top beam, a hanging rail fixed to the hanging rail connecting plate, and a hanging wheel that is fixedly connected to the artwork mounting frame and can slide along the hanging rail.

[0008] A ground track assembly is disposed at the bottom of the painting mounting frame. The ground track assembly includes a track with a length less than or equal to the length of the bottom edge of the painting mounting frame, and the painting mounting frame can move linearly along the track.

[0009] To ensure good guidance and stability when the painting mounting frame moves along the hanging rail, preferably, a front guide device and a rear guide device are provided between the bottom of the painting mounting frame and the rail to ensure that the painting mounting frame always slides in a straight line along the rail.

[0010] As a further preferred embodiment, the front guide device is disposed at the front end of the track, and guide edges are respectively disposed on both sides of the bottom of the painting mounting frame. The front guide device includes a first base fixed to the front end of the track, and two front guide wheels are disposed on the first base, which respectively correspond to and abut against the guide edges of the painting mounting frame.

[0011] To facilitate assembly and ensure stability after matching, as a further preferred embodiment, the first base has an inverted U-shaped cross-section, the dimensions of which are adapted to the cross-sectional dimensions of the track. The first base is fixedly installed at the front end of the track, serving both as a guide and a limiting device. When the artwork mounting frame is fully pulled out, the two rear guide wheels of the rear guide device abut against the first base of the front guide device, achieving a limiting effect and preventing the artwork mounting frame from slipping off the track.

[0012] Preferably, the rear guide device is located at the rear end of the track, and guide edges are respectively provided on both sides of the bottom of the painting mounting frame. The rear guide device includes a second base fixed to the bottom of the painting mounting frame, and two rear guide wheels are provided on the second base, which respectively abut against both sides of the track. Thus, when the painting mounting frame moves along the hanging track, the guiding function of the two horizontally symmetrically arranged front guide wheels can eliminate the back-and-forth swaying of the painting mounting frame.

[0013] To simplify the structure and facilitate installation, the second base preferably has an inverted U-shaped cross-section, with both ends of the inverted U-shape turned outwards horizontally to form two wings. A rear guide wheel is fixedly mounted on each wing. The rear guide wheel and the track are detachably connected, allowing the artwork mounting frame to be lifted vertically to detach from the track.

[0014] To ensure the painting mounting frame retains its guiding function even when fully extended, preferably, the bottom of the mounting frame, prior to the front guide device, is equipped with guide wheels that can directly contact the ground. These guide wheels serve both a supporting and guiding function.

[0015] When the painting mounting frame is fully extended, the rear guide device alone cannot prevent the front end of the frame from wobbling back and forth. To avoid this wobbling and improve operational stability, preferably, the guide wheel has a swing arm. This swing arm is rotatably connected to a third base via a pin. The third base is fixed to the bottom of the painting mounting frame. The end of the swing arm is connected to a bolt fixed to the bottom of the painting mounting frame. This bolt is equipped with a compression spring that ensures the guide wheel remains in contact with the ground during movement. Thus, the swing arm, in conjunction with the compression spring, applies pressure to the guide wheel, achieving frictional rolling that maintains constant contact with the ground, thereby suppressing and mitigating the back-and-forth wobbling that occurs when the painting mounting frame is extended to its front end.

[0016] To allow for the side-by-side arrangement of multiple painting mounting frames, preferably, multiple top beams are arranged in parallel intervals, and the long edge of each painting mounting frame is perpendicular to each top beam. Thus, multiple painting mounting frames can be arranged parallel to each other with spacing between them. Each painting mounting frame is vertically positioned below the top beam. When the painting mounting frame is fully pushed in, the track is retracted within the bottom edge of the frame. A passageway can be left on one side of the painting mounting frame, without tracks on the ground to avoid tripping and to facilitate the movement of vehicles and pedestrians.

[0017] To improve the stability of the painting mounting frame during movement, preferably, the hanging rail connecting plate is arranged along the length direction of the painting mounting frame and fixedly connected to each of the top beams. The length direction of the hanging rail is consistent with the length direction of the hanging rail connecting plate. Multiple hanging wheels, which can slide along the hanging rail, are spaced apart on the top of the painting mounting frame. These multiple hanging wheels can distribute the weight of the painting mounting frame and also achieve operational stability.

[0018] To achieve mechanization and automation of the movement of the painting mounting frame along the hanging rail, a wire rope drum driven by a DC motor is also installed on the top beam. The wire rope drum is wound with a steel wire that can drive the hanging wheel to slide automatically along the hanging rail. The steel wire is pulled by the pulley mechanism and then passed through the hanging rail.

[0019] Compared with existing technologies, the advantages of this invention are as follows: First, the painting mounting frame is fully supported on the hanging rail assembly, eliminating the need for load-bearing rollers at the bottom. This avoids the need to bury large areas of load-bearing roller rails on-site, resulting in a cleaner site and significantly improving the safety and aesthetics of the storage device's surrounding environment. Second, the grid on the painting mounting frame facilitates the fixing of paintings, providing excellent placement and enabling convenient and safe display. Third, it makes full use of the cabinet space, leaving sufficient passage for pedestrians or vehicles, and operation is quick and convenient. Attached Figure Description

[0030] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0031] like Figures 1-10 As shown, this embodiment discloses a push-pull painting storage device. The storage device includes a painting mounting frame 1, a hanging rail assembly 32, and a floor rail assembly. The painting mounting frame 1 is vertically suspended below a top beam 2. There are multiple top beams 2 arranged in parallel at intervals. Multiple painting mounting frames 1 can be used as needed, and they are arranged at intervals. The long edge of each painting mounting frame 1 is perpendicular to each top beam 2. Furthermore, the painting mounting frame 1 is provided with a grid 11 for fixing paintings and calligraphy. (See [reference]). Figure 2 The calligraphy and paintings 9 can be directly hung on the painting mounting frame 1 using hooks or other tools. Calligraphy and paintings 9 of different sizes can be combined and arranged on the same painting mounting frame 1. See [link / reference]. Figure 7;

[0032] like Figure 8 As shown, the hanging rail 32 assembly is used to connect the painting mounting frame 1 and the top beam 2. The hanging rail 32 assembly includes a hanging rail connecting plate 31 fixed on the top beam 2, a hanging rail 32 fixed on the hanging rail connecting plate 31, and a hanging wheel 33 fixedly connected to the painting mounting frame 1 and slidable along the hanging rail 32.

[0033] To achieve mechanization and automation of the movement of the painting mounting frame 1 along the hanging rail 32, a wire rope drum 92 driven by a DC motor 91 is also installed on the top beam 2. The steel wire 93 on the wire rope drum 92 is pulled through the hanging rail 32 by a pulley mechanism 94 also installed on the top beam 2. When the drive motor 91 is activated, the steel wire 93 is pulled out or retracted, which can drive the hanging wheel 33 to slide automatically along the hanging rail 32, thereby completing the electric control of the painting mounting frame 1. Figure 10 As shown;

[0034] The floor track assembly is located at the bottom of the painting mounting frame 1. The floor track assembly includes a track 4 with a length less than or equal to the bottom edge length of the painting mounting frame 1. The painting mounting frame 1 can move linearly along the track 4.

[0035] To improve the stability of the painting mounting frame 1 during movement, the hanging rail connecting plate 31 is set along the length direction of the painting mounting frame 1 and is fixedly connected to each top beam 2. The length direction of the hanging rail 32 is consistent with the length direction of the hanging rail connecting plate 31. The top of the painting mounting frame 1 is provided with multiple hanging wheels 33 that can slide along the hanging rail 32. The multiple hanging wheels 33 can distribute the weight of the painting mounting frame 1 and also achieve operational stability.

[0036] To ensure good guidance and stability when the painting mounting frame 1 moves along the hanging rail 32, a front guide device and a rear guide device are also provided between the bottom of the painting mounting frame 1 and the rail 4 to ensure that the painting mounting frame 1 always slides in a straight line along the rail 4.

[0037] Among them, such as Figure 3 , Figure 5As shown, the front guide device is located at the front end of the track 4, and guide edges 12 are respectively provided on both sides of the bottom of the painting mounting frame 1. The front guide device includes a first base 51 fixed to the front end of the track 4. To facilitate assembly and ensure stability after matching, the cross-section of the first base 51 is an inverted U-shape, and the cross-sectional dimensions of the concave part of the inverted U-shape are adapted to the cross-sectional dimensions of the track 4. The first base 51 is provided with two front guide wheels 52 that correspond to and abut against the guide edges 12 of the painting mounting frame 1. The first base 51 is fixedly set at the front end of the track 4, which can both guide and limit. When the painting mounting frame 1 is fully pulled out, the two rear guide wheels 62 of the rear guide device abut against the first base 51 of the front guide device to limit and prevent the painting mounting frame 1 from slipping out of the track 4.

[0038] like Figure 4 , Figure 6 As shown, the rear guide device is located at the rear end of the track 4. Guide edges 12 are respectively provided on both sides of the bottom of the painting mounting frame 1. The rear guide device includes a second base 61 fixed to the bottom of the painting mounting frame 1. The second base 61 is provided with two rear guide wheels 62 that abut against the two sides of the track 4 respectively. To simplify the structure and facilitate installation, the cross-section of the second base 61 is inverted U-shaped. The two ends of the inverted U-shape are turned outward in the horizontal direction to form two wings. A rear guide wheel 62 is fixedly provided on each wing. Thus, when the painting mounting frame 1 moves along the hanging rail 32, the guiding function of the two horizontally symmetrically arranged front guide wheels can eliminate the back-and-forth swaying phenomenon of the painting mounting frame 1. The rear guide wheels 62 and the track 4 are detachable movable connections, and the painting mounting frame 1 can be lifted vertically to detach from the track 4.

[0039] like Figure 3 As shown, when the painting mounting frame 1 is fully extended, the rear guide device alone cannot prevent the front end of the painting mounting frame 1 from wobbling back and forth. In order to ensure that the painting mounting frame 1 still has a guiding function when it is fully extended, and to avoid wobbling and improve the stability of operation, the bottom of the painting mounting frame 1 is also provided with a guide wheel 7 that can directly contact the ground in front of the front guide device. The guide wheel 7 can serve both a supporting function and a guiding function.

[0040] The guide wheel 7 has a swing arm 71, which is rotatably connected to a third base 72 via a pin 711. The third base 72 is fixed to the bottom of the painting mounting frame 1. The end of the swing arm 71 is connected to a bolt 73 fixed to the bottom of the painting mounting frame 1. A compression spring 74 is provided on the bolt 73 to ensure that the guide wheel 7 is always in contact with the ground during movement. The guide wheel 7 is pressed against the ground by the compression spring 74, that is, it is on the same horizontal plane as the bottom plane of the track 4. Thus, by using the swing arm 71 in conjunction with the compression spring 74, pressure can be applied to the guide wheel 7 to achieve frictional rolling that is always in contact with the ground, thereby suppressing and improving the back-and-forth swaying phenomenon that occurs when the painting mounting frame 1 is pulled out to its foremost position.

[0041] In this embodiment, the push-pull painting storage device can be used by manually pulling the painting mounting frame 1 out of the track 4 or pushing it back. The side of the painting mounting frame 1 is provided with a handle 13, and the painting mounting frame 1 can also be moved and retracted by electric means.

[0042] In this embodiment, the length of track 4 is set to be less than or equal to the length of the painting mounting frame 1. That is, when each painting mounting frame 1 is fully pushed in, track 4 is completely retracted within the bottom edge of the painting mounting frame 1, and track 4 is not exposed outside the painting mounting frame 1. A passageway 8 can be left on one side of the painting mounting frame 1, such as... Figure 1 As shown by the dashed line, a set of storage devices with the same structure can be symmetrically arranged on the other side of the passageway 8. The distance between the two sets of storage devices should be just enough to allow pedestrians or vehicles to pass through when the picture mounting frame 1 of one of the storage devices is fully extended. Since there is no track 4 on the ground of the passageway 8, tripping is avoided, and it is convenient for vehicles to push and pedestrians to walk, thus improving the safety of use.
