Description

Technical Field

[0001] This utility model relates to the field of paper-cutting mounting technology, and in particular to a mounting device for paper-cutting. Background Technology

[0002] Paper-cutting mounting refers to the process of protecting, fixing, and decorating paper-cutting works through specific techniques and materials, making them easier to preserve, display, and enhance their artistic appeal. It is an important part of paper-cutting art creation.

[0003] The multi-layered nature and rich color expression of modern paper-cutting works, on the contrary, lack a sense of three-dimensionality and rhythm. They are even less lively than traditional paper-cutting works created with a single technique. This makes it impossible to fully display the artistic tension and craftsmanship of modern paper-cutting works, which greatly affects the visual effect and artistic expression.

[0004] The existing patent (publication number: CN208867772U) describes a paper-cut decoration with light and shadow effects, which enhances the ethereal and floating transparency of the paper-cut layers, giving the picture a strong three-dimensional effect. It fully reflects the advantages and characteristics of modern paper-cutting in terms of visual aspects, greatly enhances the artistic expression and craftsmanship of the work, and gives people a unique visual enjoyment.

[0005] To address the aforementioned problems, existing patents have provided solutions. However, most existing frame structures for mounting paper-cuts have low sealing performance. After the paper-cuts are mounted and hung for display, they are easily affected by air humidity, causing them to become damp, fade, or even moldy, which greatly affects the artistic value of the paper-cut works.

[0006] Therefore, a mounting device for paper cutting is proposed. Utility Model Content

[0007] The purpose of this invention is to provide a mounting device for paper-cutting, which can solve the problem that most existing mounting frames for paper-cutting have low sealing performance, making them susceptible to air humidity after mounting and hanging, leading to the paper-cutting becoming damp, fading, or even moldy, which greatly affects the artistic value of the paper-cutting works.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a mounting device for paper cutting, comprising a front frame and a rear frame, wherein a high-transparency glass is fixedly connected to the inner wall of the front frame, a dehumidification mechanism is provided inside the rear frame, and a sealing gasket is fixedly connected to the rear side of the front frame.

[0009] The dehumidification mechanism includes a fixing hole, a dehumidification box, a cover, a mesh, and a cotton-linen cloth. The fixing hole is located inside the rear frame. The surface of the dehumidification box is fixedly connected to the inner wall of the fixing hole. The surface of the cover is threadedly connected to the inside of the dehumidification box. The mesh is embedded in the front side of the inner wall of the dehumidification box. The back side of the cotton-linen cloth is fixedly connected to the front side of the rear frame. The cotton-linen cloth covers the fixing hole.

[0010] Preferably, a sealing ring is fitted onto the surface of the cover, and the front side of the sealing ring is in close contact with the rear side of the dehumidification box.

[0011] Preferably, the surface of the cover is fixedly connected with a screw block, and the number of screw blocks is several and they are evenly distributed on the surface of the cover.

[0012] Preferably, the rear frame has a slot inside, and the sealing gasket is tightly engaged inside the slot.

[0013] Preferably, the surface of the front frame is provided with a connecting mechanism. The number of connecting mechanisms is several and they are evenly distributed on the surface of the front frame. The connecting mechanism includes two limiting strips, an elastic clip, two limiting blocks, and a limiting groove. The two limiting strips are respectively fixedly connected to the front and rear sides of the inner wall of the elastic clip. The side of the rear limiting block near the rear frame is fixedly connected to the surface of the rear frame, and the side of the front limiting block near the front frame is fixedly connected to the surface of the front frame. The limiting groove is opened inside the limiting block. The surface of the limiting strip contacts the inner wall of the limiting groove, and the inner wall of the elastic clip contacts the surface of the limiting block.

[0014] Preferably, both sides of the top rear side of the rear frame are fixedly connected to a rotating frame, and a hanging ring is rotatably connected inside the rotating frame.

[0015] Preferably, rubber blocks are fixedly connected to both sides of the bottom rear side of the rear frame.

[0016] Preferably, both the sealing gasket and the sealing ring are made of EPDM rubber.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. This application sets up a dehumidification mechanism. After the paper-cutting works are mounted by the front and back frames, the sealing ring and sealing gasket play a sealing role. Then, the external silica gel desiccant particles are added to the dehumidification box, so that the external silica gel desiccant particles can absorb moisture from the paper-cutting works, ensuring that the paper-cutting works are preserved and displayed in a sealed and dry environment.

[0019] 2. This application sets up a connecting mechanism. By moving the elastic card until it contacts the inner wall of the limiting strip and the limiting groove, the two limiting blocks can be connected, which facilitates the connection of the front frame and the back frame, making it convenient to mount the paper-cutting works. Furthermore, by pulling the elastic card forcefully later, overcoming its elastic deformation, the limiting strip and the limiting groove can be separated, allowing the front frame and the back frame to be disassembled, making it convenient to replace the paper-cutting works.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figure 1-8 The present invention provides the following technical solution:

[0031] A mounting device for paper cutting includes a front frame 1 and a rear frame 3. A high-transparency glass 2 is fixedly connected to the inner wall of the front frame 1, a dehumidification mechanism 7 is provided inside the rear frame 3, and a sealing gasket 5 is fixedly connected to the rear side of the front frame 1.

[0032] The dehumidification mechanism 7 includes a fixing hole 701, a dehumidification box 702, a cover 703, a mesh 704, and a cotton linen cloth 705. The fixing hole 701 is opened inside the rear frame 3. The surface of the dehumidification box 702 is fixedly connected to the inner wall of the fixing hole 701. The surface of the cover 703 is threadedly connected to the inside of the dehumidification box 702. The mesh 704 is embedded in the front side of the inner wall of the dehumidification box 702. The rear side of the cotton linen cloth 705 is fixedly connected to the front side of the rear frame 3. The cotton linen cloth 705 covers the fixing hole 701.

[0033] In this embodiment: the paper-cut is first laid flat on the inside of the high-transparency glass 2 of the front frame 1, and then attached to the rear frame 3. The sealing gasket 5 of the front frame 1 is inserted into the slot 6 of the rear frame 3. The sealing gasket 5, made of EPDM rubber, isolates moisture and dust. The elastic card 402 is pushed, causing the limiting strip 401 to deform under the pressure of the limiting block 403 and slide into the limiting groove 404. After the elastic card 402 rebounds, the front frame 1 and the rear frame 3 are firmly positioned. At the same time, the cotton and linen cloth 705 presses the paper-cut tightly against the surface of the high-transparency glass 2, completing the initial sealing. To keep the inside dry, the cover 703 is turned to open the dehumidification box 702 and an external silica gel desiccant is placed in. The sealing ring 11 of the cover 703 is also made of EPDM rubber to ensure dehumidification. The box 702 is airtight, and the mesh 704 supports the external silica gel desiccant particles, preventing compression of the paper-cutting artwork. The cotton and linen cloth 705 also functions as a background cloth; its breathability allows the desiccant to effectively absorb moisture from the gap between the high-transparency glass 2 and the cotton and linen cloth 705, preventing the paper-cutting from getting damp and moldy, and ensuring long-term dry preservation of the paper-cutting artwork. The external silica gel desiccant particles inside the dehumidifying box 702 can be easily replaced by rotating and opening the lid 703. This solves the problem that most existing frame structures for mounting paper-cutting have low sealing performance, making them susceptible to air humidity after mounting and hanging, leading to dampness, fading, and even mold, which greatly affects the artistic value of the paper-cutting artwork.

[0034] Specifically, such as Figure 4 and Figure 8 As shown, a sealing ring 11 is fitted on the surface of the cover 703, and the front side of the sealing ring 11 is in close contact with the rear side of the dehumidification box 702.

[0035] Specifically, such as Figure 8 As shown, a screw block 12 is fixedly connected to the surface of the cover 703. The screw block 12 is a number and is evenly distributed on the surface of the cover 703.

[0036] Specifically, such as Figure 6 As shown, a slot 6 is provided inside the rear frame 3, and the sealing gasket 5 is tightly engaged inside the slot 6.

[0037] In this embodiment: the cover 703 and the dehumidification box 702 are sealed by the sealing ring 11, ensuring that the dehumidification box 702 can be sealed after the front frame 1 and the rear frame 3 are connected. The cover 703 can be easily rotated by hand-twisting block 12. By tightly engaging the sealing gasket 5 inside the slot 6, the sealing between the front frame 1 and the rear frame 3 can be guaranteed.

[0038] Specifically, such as Figure 1 and Figure 5 As shown, a connecting mechanism 4 is provided on the surface of the front frame 1. The number of connecting mechanisms 4 is several and they are evenly distributed on the surface of the front frame 1. The connecting mechanism 4 includes two limiting strips 401, elastic clips 402, two limiting blocks 403 and limiting grooves 404. The two limiting strips 401 are fixedly connected to the front and rear sides of the inner wall of the elastic clips 402, respectively. The side of the rear limiting block 403 near the rear frame 3 is fixedly connected to the surface of the rear frame 3, and the side of the front limiting block 403 near the front frame 1 is fixedly connected to the surface of the front frame 1. The limiting groove 404 is opened inside the limiting block 403. The surface of the limiting strip 401 contacts the inner wall of the limiting groove 404, and the inner wall of the elastic clip 402 contacts the surface of the limiting block 403.

[0039] Specifically, such as Figure 7 As shown, both sides of the top rear side of the rear frame 3 are fixedly connected to a rotating frame 9, and a hanging ring 10 is rotatably connected inside the rotating frame 9.

[0040] In this embodiment: by pushing the elastic card 402 toward the limiting block 403, the elastic card 402 deforms, moving the limiting strip 401 into the limiting groove 404. At this time, the elastic card 402 rebounds, so that the inner wall of the elastic card 402 contacts the surface of the limiting block 403, thereby limiting the two limiting blocks 403 together, thus limiting the front frame 1 and the rear frame 3 together. The rotating hanging ring 10 inside the rotating frame 9 makes it convenient to hang the paper-cutting works that have been mounted by the front frame 1 and the rear frame 3 on the wall.

[0041] Specifically, such as Figure 4 As shown, rubber blocks 8 are fixedly connected to both sides of the bottom rear side of the rear frame 3.

[0042] Specifically, such as Figure 6 and Figure 8 As shown, both the sealing gasket 5 and the sealing ring 11 are made of EPDM rubber.

[0043] In this embodiment: the rubber blocks 8 on both sides of the bottom rear side of the rear frame 3 can prevent the rear frame 3 from causing wear and tear on the wall. The sealing gasket 5 and sealing ring 11 made of EPDM material have good corrosion resistance and sealing performance, ensuring that the paper-cutting works are preserved and displayed in a sealed and dry environment.

[0044] Working principle: When mounting a paper-cut artwork, first lay the artwork flat on the inside of the high-transparency glass 2 of the front frame 1. Then, attach the back frame 3 to the front frame 1. At this time, the sealing gasket 5 on the back side of the front frame 1 is tightly inserted into the slot 6 of the back frame 3. Since the sealing gasket 5 is made of EPDM rubber, its excellent sealing and corrosion resistance can effectively isolate external moisture and dust. Then, the elastic clip 402 is pushed towards the limiting block 403. At this time, the limiting block 403 compresses the limiting strip 401, causing the elastic clip 402 to deform, causing the limiting strip 401 to move into the limiting groove 404. 2. The springback causes the inner wall of the elastic card 402 to contact the surface of the limiting block 403, thus limiting the two limiting blocks 403 together, thereby limiting the front frame 1 and the rear frame 3 together. At the same time, the cotton linen cloth 705 presses the paper-cut artwork firmly against the surface of the high-transparency glass 2, completing the initial sealing. To ensure a dry internal environment, the screw block 12 on the cover 703 is rotated to open the dehumidifier box 702, and the external silica gel desiccant particles are placed inside. The sealing ring 11 on the surface of the cover 703 is also made of EPDM rubber and fits tightly with the dehumidifier box 702, ensuring that the dehumidifier box 702 can open after the front frame 1 and the rear frame 3 are connected. The sealed mesh 704 supports the external silica gel desiccant particles, preventing compression of the paper-cut artwork. The cotton linen cloth 705 covers the fixing holes 701, serving as a background cloth for the artwork and providing excellent breathability, allowing the external silica gel desiccant particles to absorb moisture. The external silica gel desiccant particles continuously absorb moisture from the gap between the high-transparency glass 2 and the cotton linen cloth 705, ensuring the paper-cut artwork remains in a dry environment and preventing mold growth. This solves the problem of low sealing performance in most existing frame structures for mounting paper-cuts, which are easily affected by air humidity after mounting and hanging. The problem of paper-cutting becoming damp, fading, or even moldy greatly affects its artistic value. When the external silica gel desiccant fails, the cover 703 can be opened again for replacement. If the paper-cutting needs to be removed or replaced later, pull the elastic clip 402 forcefully to overcome its elastic deformation, so that the limiting strip 401 separates from the limiting groove 404, and the front frame 1 and the rear frame 3 can be disassembled. In addition, the hanging ring 10 on the top rear side of the rear frame 3 is connected by a rotating frame 9 for easy hanging and display of the device. The rubber block 8 at the bottom can buffer the contact between the device and the wall to avoid abrasion and improve the safety and practicality of use.

[0045] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
