Abstract
Description
Technical Field
[0001] The present application relates to the technical field of artwork exhibition equipment, and in particular to an art work display device. Background Art
[0002] Fine arts refer to art that occupies a certain space and has visual images for appreciation, including painting, sculpture, arts and crafts, etc. The scope of fine arts is very broad. Generally speaking, it can be roughly divided into two types: ornamental art and practical art; in terms of ornamental art, it mainly includes two categories: painting and sculpture. As for painting, due to the different materials and tools used, it can be divided into Chinese painting, oil painting, watercolor painting, gouache painting, printmaking, sketching and other types of painting. Sculptures also have many forms such as round sculptures and reliefs, and the materials used are stone, wood, mud, plaster, bronze, etc. Studying fine arts can not only improve people's aesthetic ability but also cultivate creativity and imagination. Therefore, whether in primary and secondary schools or in college, art education is a very important part.
[0003] When students study or research art works, they often need to put multiple paintings together for comparison and observation. However, the existing display racks can only display one art work at a time. If more art works are to be displayed at the same time, it is necessary to increase the number of display racks or paste the excess art works on the blackboard. Increasing the number of display racks will not only take up classroom space and affect teaching, but also require a larger space to store them after subsequent use, which is inconvenient to use. If multiple paintings are pasted on the blackboard, the teacher's writing area on the blackboard will be reduced. Utility Model Content

DETAILED DESCRIPTION
[0032] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application is clearly and completely described below. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work also fall within the scope of protection of the present application.
[0033] like Figure 1-Figure 4 As shown, an art work display device disclosed in the present application comprises a movable base 1, a storage sleeve 2 is installed on the base 1, an extension tube 3 is inserted into the storage sleeve 2 and the two are slidably connected along the vertical direction; one or more storage through holes 4 are provided on the extension tube 3 along the vertical direction (wherein, preferably two storage through holes 4 are provided, such as Figure 1 and Figure 2 As shown), each storage hole 4 is provided with a display component 5; the display component 5 includes two frame placement rods 51, and the mutually close ends of the two frame placement rods 51 are movably mounted on the same rotating shaft 52, and the rotating shaft 52 is fixedly connected to the inner wall of the storage hole 4, and the two frame placement rods 51 are each provided with a strip groove 53 along the length direction; a picture frame 6 is placed in the strip groove 53; the height of the storage hole 4 is not less than the length of the frame placement rod 51, and the width of the storage hole 4 is not less than the sum of the heights of the two frame placement rods 51.
[0034] In the above embodiments, the storage sleeve 2 and the extension tube 3 of the present application are both square tubes, which is convenient for production and processing. The close ends of the two frame placement rods 51 located in the same storage through hole 4 are hinged together through the same rotating shaft 52, and the rotating shaft 52 is located in the middle position of the lower end of the storage through hole 4, so that the two frame placement rods 51 can not only rotate freely along the rotating shaft 52, but also when the two frame placement rods 51 rotate to a horizontal state, the lower sides of their close ends will contact the lower side wall of the storage through hole 4, thereby forming a limit for the two frame placement rods 51 so that they can maintain a horizontal state. When the two frame placement rods 51 are rotated upward to a vertical state, the height of the two frame placement rods 51 is slightly smaller than the width of the storage through hole 4 (the length, width and height of the frame placement rods 51 mentioned in this application are the length, width and height when they are in a horizontal state), so that the two frame placement rods 51 can be completely stored in the storage through holes 4 at the corresponding positions after use or when waiting to be used, and when the extension tube 3 is placed in the storage sleeve 2, the two frame placement rods 51 will not affect the movement of the extension tube 3. There is a certain damping between the two frame placement rods 51 and the rotating shaft 52, so that when the frame placement rods 51 move downward or upward with the extension tube 3, the frame placement rods 51 can be prevented from automatically detaching from the storage through hole 4 and causing harm to the user.
[0035] The picture frame 6 of the present application can frame the paintings that need to be compared, thereby protecting the paintings to a certain extent, and the width of the bottom of the picture frame 6 is similar to the width of the strip groove 53 on the frame placement rod 51, so that when the picture frame 6 is inserted into the strip groove 53 on the frame placement rod 51, the picture frame 6 can be prevented from shaking back and forth.
[0036] like Figure 8 As shown, when students need to study or research multiple paintings, the teacher can bring the display device of the present application to the classroom, then pull out the extension tube 3 from the storage sleeve 2, and then rotate the multiple frame placement rods 51 in turn to a horizontal state. At this time, the paintings that need to be compared are loaded into the picture frames 6 and placed in the bar grooves 53 on each frame placement rod 51 in turn, and the students can start to study or research the art works. Compared with the display racks used in the prior art that can only display one pair at a time, the present application saves the trouble of preparing multiple display racks when displaying multiple paintings, and it will not take up a lot of space in the classroom. Moreover, if the display device of the present application is to display more paintings, the height of the storage sleeve 2 and the extension tube 3 can be increased while adaptively increasing the number of storage through holes 4 and display components 5. Compared with the method of posting multiple paintings on the blackboard in the prior art, the present application can save the trouble of occupying blackboard space. Figure 7 As shown, after use, compared with the prior art which uses multiple display racks that can only display a single painting, the present application can be folded and stored, which is not only more efficient to operate but also occupies less space when stored.
[0037] Furthermore, if Figure 6 As shown, a first through hole 7 is provided at the lower end of the extension tube 3, and a second through hole 8 is provided at the upper end of the storage sleeve 2; after the extension tube 3 moves upward along the axis of the storage sleeve 2 until the first through hole 7 is connected to the second through hole 8, the pin can be passed through the through hole formed by the second through hole 8 and the first through hole 7, thereby fixing the extension tube 3 and the storage sleeve 2.
[0038] In the above embodiment, the first through hole 7 at the lower end of the extension tube 3 has the same specifications as the second through hole 8 on the storage sleeve 2. When the extension tube 3 moves upward along the storage sleeve 2 until the first through hole 7 and the second through hole 8 are aligned, the first through hole 7 and the second through hole 8 can be connected to form a through hole. At this time, the user inserts a pin that matches the specifications of the through hole to connect the extension tube 3 and the storage sleeve 2, and forms a limit on the extension tube 3 on the storage sleeve 2 so that the extension tube 3 will not retract into the storage sleeve 2 when multiple paintings are displayed.
[0039] Furthermore, if Figure 5 As shown, the picture frame 6 includes a display board 61, on which transparent glass is installed, and a placement groove 62 is provided below the display board 61 and the two are fixedly connected; two symmetrical limit baffles 63 are installed on the back of the display board 61, and the limit baffles 63 and the display board 61 are not only parallel to each other but also have a gap therebetween.
[0040] In the above embodiment, the user can place the painting in the placement groove 62 through the gap between the display board 61 and the limit baffle 63, and when placing the painting, the picture on the painting should face the display board 61, so that the students can clearly see the painting inside through the transparent glass on the display board 61, and in the process of learning, the students or teachers can mark some contents on the painting on the transparent glass, which is not only convenient for learning and research, but also can better protect the painting.
[0041] Furthermore, if Figure 5 As shown, a fastening component 9 is provided on one side of the strip groove 53 , and the picture frame 6 can be fixed by the fastening component 9 after being placed in the strip groove 53 .
[0042] In the above embodiments, since the picture frame 6 containing the painting is simply placed on the frame placement rod 51 without any actual connection, there is still a risk of it falling during use. The present application connects the picture frame 6 to the strip groove 53 by providing a fastening component 9 in the strip groove 53, which can reduce the risk of the picture frame 6 falling during the process of displaying the painting.
[0043] Furthermore, if Figure 5As shown, the fastening assembly 9 includes a mounting groove 91 arranged on one of the outer side walls in the width direction of the frame placement rod 51, a movable flap 92 is arranged in the mounting groove 91, one end of the movable flap 92 is hinged in the mounting groove 91, and a first positioning hole 93 is arranged on the movable flap 92; a fixed connecting plate 94 is arranged on the upper side of the placement groove 62 away from one end of the display board 61, and a second positioning hole 95 is arranged on the fixed connecting plate 94; after the picture frame 6 is placed in the strip groove 53, when the movable flap 92 is rotated upward to be parallel to the fixed connecting plate 94, the axes of the first positioning hole 93 and the second positioning hole 95 are collinear; the first positioning hole 93 and the second positioning hole 95 are both threaded holes.
[0044] In the above embodiment, a movable flap 92 with a similar groove shape is provided in the mounting groove 91, so that the movable flap 92 can be hidden in the mounting groove 91 of the frame placement rod 51 when not in use, and in this state, the upper end of the movable flap 92 is hinged with the mounting groove 91. When the lower end of the movable flap 92 rotates upward around the hinge point with the mounting groove 91, the first positioning hole 93 on the movable flap 92 can be aligned with the second positioning hole 95 on the fixed connecting plate 94 on the back of the picture frame 6. Since the first positioning hole 93 and the second positioning hole 95 are threaded holes of the same specification, the user can connect the picture frame 6 and the frame placement rod 51 together by screwing a bolt that matches their specifications into the first positioning hole 93 and the second positioning hole 95, thereby avoiding the picture frame 6 from accidentally falling from the frame placement rod 51 during use.
[0045] Furthermore, if Figure 5 As shown, a third positioning hole 10 is provided in the mounting groove 91 , and the third positioning hole 10 is a threaded hole with the same specifications as the first positioning hole 93 and the second positioning hole 95 , and the distance between the third positioning hole 10 and the first positioning hole 93 and the axis of the hinge shaft of the movable flap 92 is equal.
[0046] In the above embodiment, the third positioning hole 10 provided on the mounting groove 91 of the present application can be aligned with the first positioning hole 93 on the movable flap 92 when the movable flap 92 is hidden in the mounting groove 91. Since the third positioning hole 10 and the first positioning hole 93 and the second positioning hole 95 are all internal threaded holes of the same specification, the aligned third positioning hole 10 and the first positioning hole 93 can form a connected deep threaded hole. At this time, the bolt used to connect the first positioning hole 93 and the second positioning hole 95 can be passed through the first positioning hole 93 and the third positioning hole 10 in sequence. This can not only fix the movable flap 92 hidden in the mounting groove 91, but also temporarily store the bolts used to connect the first positioning hole 93 and the second positioning hole 95. When the movable flap 92 needs to be used to fix the picture frame 6, the bolts of the first positioning hole 93 and the third positioning hole 10 are unscrewed, and then after the first positioning hole 93 and the second positioning hole 95 are aligned, the bolts are used to screw them back into the first positioning hole 93 and the second positioning hole 95.
[0047] Furthermore, if Figure 5 and Figure 7 As shown, a pull ring 11 is provided on the top of the extension tube 3 .
[0048] In the above embodiments, the pull ring 11 is provided to facilitate the user to pull the extension tube 3 out of the storage sleeve 2 .
[0049] Furthermore, if Figure 5 and Figure 7 As shown, a gripping area 12 is provided on the outer side of the upper end of the storage sleeve 2 .
[0050] In the above embodiments, the gripping area 12 provided on the storage sleeve 2 facilitates the user to grip the storage sleeve 2 and then move the entire device through the storage sleeve 2 .
[0051] Furthermore, if Figure 2 As shown, an artwork placement frame 13 is provided on the base 1 at one side of the storage sleeve 2 , and an oblique opening is provided at the upper end of the artwork placement frame 13 .
[0052] In the above embodiment, the artwork placement frame 13 can be used to store the picture frame 6 and multiple paintings. The upper end of the artwork placement frame is an oblique opening, which makes it convenient for users to quickly find and take out the required paintings from the artwork placement frame 13.
[0053] Furthermore, if Figure 2 As shown, two sculpture placement frames 14 are provided on the base 1. The two sculpture placement frames 14 are located on the base 1 on the side of the art placement frame 13 close to the storage sleeve 2, and the two sculpture placement frames 14 are symmetrical about the storage sleeve 2; anti-collision sponges are laid in the two sculpture placement frames 14.
[0054] In the above embodiment, the two sculpture placement frames 14 added to the base 1 can further utilize the space on the base 1. In the process of art teaching, since some plaster sculptures are often used, the sculpture placement frame 14 of the present application can be used to temporarily place these plaster sculptures. The anti-collision sponge laid in the sculpture placement frame 14 can protect the plaster sculptures when storing these plaster sculptures.
[0055] The implementation principle of this embodiment is as follows: when students need to compare and study multiple paintings, the teacher can move the entire device from the office or the special teaching tool storage room to the classroom through the movable wheels with self-locking function under the movable base 1, and then pull out the extension tube 3 from the storage sleeve 2. When the first through hole 7 under the extension tube 3 is aligned with the second through hole 8 on the storage sleeve 2, the latch is inserted to keep the extension tube 3 in the extended state. Then all the multiple frame placement rods 51 are opened to make them in a horizontal state. Then the teacher puts the paintings to be compared into the picture frame 6 one by one, and then places the multiple picture frames 6 on different frame placement rods 51 respectively, and then removes the bolts from the movable flap 92, flips the movable flap 92 upward to align the first positioning hole 93 on it with the second positioning hole 95 on the fixed connecting plate 94 at the back of the picture frame 6 at the corresponding position, and then uses the removed bolts to fix the picture frame 6 and the movable flap 92 together.
[0056] After use, the teacher can first remove the bolts connecting the picture frame 6 and the movable flap 92 one by one, and after the movable flap 92 is reset, use the bolts to fix the movable flap 92 on the corresponding frame placement rod 51. Then, the multiple frame placement rods 51 are retracted into the storage through holes 4 at the corresponding positions, the latch between the extension tube 3 and the storage sleeve 2 is removed, and the extension tube 3 is put back into the storage sleeve 2. Finally, the device can be moved back to the office or a special teaching tool storage room through the storage sleeve 2.
[0057] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, ordinary technicians in the field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present application.
