Description

Technical Field

[0001] This utility model relates to the field of couplet fixing technology, specifically to a couplet frame structure. Background Technology

[0002] Pasting couplets is a traditional custom, and the common method is to use glue or adhesive strips to attach them to suitable positions on the vertical facade of a building. This method is common and simple, but it has the drawback of being relatively troublesome when changing the couplets, as well as in the process of fixing them to the building's vertical facade.

[0003] To make changing couplets more convenient, some new couplet fixing technologies and structures have been developed. These structures generally have a couplet backing board fixed in a corresponding position on the wall, thus providing a preliminary positioning aid. Then, the couplet paper is fixed to the couplet backing board by magnetic means or window-mounting-like means (using a transparent board to fix the couplet paper between the transparent board and the couplet backing board), thereby solving the problems of positioning and pasting trouble when changing couplets.

[0004] However, the above-mentioned technology only improves the process of fixing couplets by changing the pasting process to other types of detachable connection processes. Whether it is magnetic or similar to window mounting, it still requires people to go to a high place to fix the top of the couplets and the backing board. Therefore, there are still technical problems that are troublesome to operate and pose safety hazards. Utility Model Content

[0005] To address the technical problems identified in the background section of the prior art, this utility model provides a couplet frame structure. The technical problem to be solved by this utility model is achieved through the following technical solution:

[0006] A couplet frame structure, comprising:

[0007] The main back panel of the couplet is fixed to the wall or column;

[0008] The first clamping element is located at the top of the main back panel of the couplet;

[0009] The second clamping component is located at the bottom of the main back panel of the couplet;

[0010] Two frame strips are respectively set on both sides of the main back panel of the couplet in the width direction. The two frame strips have grooves parallel to the main back panel of the couplet on their opposite sides. The grooves have openings at the bottom of the frame strips. The two sides of the couplet carrying plate in the width direction are slidably connected to the grooves of the frame strips on the same side. The two sides of the couplet carrying plate in the width direction can enter / exit the corresponding grooves from the corresponding openings.

[0011] The couplet carrying plate is slidably connected between two side strips, and the couplet carrying plate can enter / exit between the two side strips from the bottom end of the couplet main back plate. The couplet carrying plate is configured such that its surface can cover and connect the couplet. The two ends of the couplet carrying plate in the length direction are respectively clamped by a first clamping member and a second clamping member. The rigidity of the couplet carrying plate is stronger than that of the couplet, and the upper end of the couplet carrying plate can be squeezed into the first clamping member and thus be clamped.

[0012] Furthermore, each of the two side panels facing each other has a mounting groove parallel to the slot, and the two sides of the main back panel of the coupler can be detachably embedded into the mounting groove on the same side.

[0013] Furthermore, it also includes: a box body, one side of which has an opening, the upper ends of the couplet back plate and the frame strip can enter the box body through the opening, the frame strip abuts against the inner side of the box body in the width direction of the couplet carrying plate, and the first clamping member is located inside the box body.

[0014] Furthermore, a photovoltaic panel is installed on the outer side of the box, and a charging power supply is installed inside the box. The photovoltaic panel is charged through an electrical connection to the charging power supply. A light strip groove parallel to the frame strip is opened on the inner side wall of the slot. A light strip is installed in the light strip groove, and one end of the light strip extends into the box and is electrically connected to the charging power supply.

[0015] Furthermore, the couplet is attached to the surface of the couplet carrying plate facing the main back plate of the couplet, and the couplet carrying plate is a transparent plate, so that the content of the couplet can be observed through the couplet carrying plate.

[0016] Furthermore, the first clamping member includes: a first fixing part, a first pressing part, and an elastic part. The first fixing part is fixedly connected to the upper end of the main back plate of the couplet, the first pressing part is hinged to the first fixing part, and the elastic part is connected between the first fixing part and the first pressing part. Under the elastic force of the elastic part, the first pressing part can press against the side of the couplet carrying plate away from the main back plate of the couplet, thereby clamping the upper end of the couplet carrying plate between the first pressing part and the main back plate of the couplet.

[0017] Furthermore, a warping edge is provided on the side of the first pressing part facing the bottom end of the couplet main back plate. The warping edge warps toward the side away from the couplet main back plate. The stiffness of the couplet carrying plate is configured to overcome the elastic force of the elastic part under the guidance of the warping edge, so that the upper end of the couplet carrying plate can be squeezed between the first pressing part and the couplet main back plate.

[0018] Furthermore, the second clamping member includes: a second fixing part, a second pressing part, and a locking mechanism. The second fixing part is fixedly connected to the lower end of the main back plate of the couplet, and the second fixing part is located on the side of the main back plate of the couplet away from the couplet carrying plate. The second pressing part is hinged to the lower end of the second fixing part, and the second pressing part can rotate around the hinge point between itself and the second fixing part to the side of the main back plate of the couplet facing the couplet carrying plate. The locking mechanism is disposed between the second fixing part and the second pressing part. When the second pressing part presses the couplet carrying plate against the main back plate of the couplet, the locking mechanism can lock the relative position of the second fixing part and the second pressing part, thereby clamping the lower end of the couplet carrying plate between the second pressing part and the main back plate of the couplet.

[0019] Furthermore, the locking mechanism includes a magnetic suction component. A mounting hole is provided at the lower end of the main back plate of the couplet. A second fixing part is located at one end of the mounting hole. The magnetic suction component is fixedly connected to the side of the second fixing part facing the main back plate of the couplet and is located inside the mounting hole. When the second pressing part presses the couplet carrying plate against the main back plate of the couplet, the magnetic suction component can magnetically attract the second pressing part, thereby locking the relative position of the second fixing part and the second pressing part.

[0020] Furthermore, the outer diameter of the end of the magnetic attractor facing the second pressing part is larger than the inner diameter of the mounting hole, and the outer diameter of the end of the magnetic attractor facing the second fixing part is smaller than the inner diameter of the mounting hole.

[0021] The beneficial effects of this utility model are as follows: The couplet is covered and connected to the couplet carrying plate. Pushing the couplet carrying plate causes it to slide between the two side strips. With the rigidity of the couplet carrying plate, the couplet carrying plate and the couplet are squeezed into the first clamping member. Then, the lower end of the couplet carrying plate is fixed by the second clamping member, thus completing the fixation of the couplet. In this process, because the couplet carrying plate has stronger rigidity, it is not easy to change or bend during the sliding process. It can slide vertically upward under the limiting guidance of the side strips and finally squeeze into the first clamping member by relying on the rigidity of the couplet carrying plate, thus completing the fixation of its upper end. In the whole process, the personnel do not need to go to a high place to perform the fixing operation. They only need to operate at the bottom of the couplet main back plate to complete the setting of the couplet conveniently and quickly, thereby solving the technical problems mentioned in the background art.

Detailed Implementation

[0031] The present invention will be further described in detail below with reference to specific embodiments, but the implementation of the present invention is not limited thereto.

[0032] This utility model provides a couplet frame structure, including: a couplet main back plate 1, a first clamping member 2, a second clamping member 3, two side strips 4, and a couplet carrying plate 5, etc. The couplet main back plate 1 is fixed to a wall or column. The first clamping member 2 is disposed at the top of the couplet main back plate 1. The second clamping member 3 is disposed at the bottom of the couplet main back plate 1. The two side strips 4 are respectively disposed on both sides of the couplet main back plate 1 in the width direction. The couplet carrying plate 5 is slidably connected between the two side strips 4, and the couplet carrying plate 5 can enter / exit between the two side strips 4 from the bottom of the couplet main back plate 1. The couplet carrying plate 5 is configured such that its surface can cover and connect the couplet. The two ends of the couplet carrying plate 5 in the length direction are clamped by the first clamping member 2 and the second clamping member 3, respectively. The rigidity of the couplet carrying plate 5 is stronger than that of the couplet.

[0033] Specifically, refer to Figures 1 to 6In use, the main back plate 1 of the couplet is fixed to the wall or column, the couplet is covered and connected to the couplet carrying plate 5, and the couplet carrying plate 5 is pushed so that it slides between the two frame strips 4. The couplet carrying plate 5 is continued to be pushed until it carries the couplet into place. With the rigidity of the couplet carrying plate 5, the couplet carrying plate 5 and the couplet are squeezed into the first clamping member 2. Then, the lower end of the couplet carrying plate 5 is fixed by the second clamping member 3, thus completing the fixation of the couplet. When it is necessary to replace the couplet, the clamping member 3 is released from the couplet carrying plate 5, the couplet carrying plate 5 is pulled out from the first clamping member 3, and finally the couplet carrying plate 5 is slid out from the bottom end of the two frame strips 4. The old couplet is removed from the couplet carrying plate 5, and then the new couplet is connected to the couplet carrying plate 5. Finally, the couplet carrying plate 5 is slid back between the two frame strips 4 from the bottom end, realizing the quick replacement of the couplet.

[0034] In the above process, the method of sliding the couplets onto the main back plate 1 from the bottom is convenient and quick. For couplets posted at a high place, this bottom-up sliding method can avoid the need for personnel to operate from a high position. However, since it is a bottom-up sliding process, if only the couplet paper is slid in, the paper often lacks rigidity and is prone to bending and deformation during the sliding process, causing the upper end to curl and droop. Furthermore, its easy bending and deformation means that the side frame strips 4 cannot provide a good limiting function. When sliding against the frame strips 4, the edges of the paper may fold and break. Also, the upper end of the couplet paper is difficult to squeeze into the first clamping member 2, thus affecting the operation process. Therefore, a couplet carrying plate 5 is specially designed. The couplet carrying plate 5 carries the couplet and slides between the two frame strips 4. Because the couplet carrying plate 5 has stronger rigidity, it is not easy to change or bend during the sliding process. It can slide vertically upward under the limiting guidance of the frame strips 4, and finally squeeze into the first clamping member 2 by relying on the rigidity of the couplet carrying plate 5 to complete the fixation of its upper end. In the whole process, the personnel do not need to go to a high place to perform the fixing operation. They only need to operate at the bottom of the couplet main back plate 1 to complete the setting of the couplet conveniently and quickly, thereby solving the technical problems mentioned in the background art.

[0035] In this embodiment, the couplet is attached to the surface of the couplet carrying plate 5 facing the main back plate 1, and the couplet carrying plate 5 is a transparent plate, allowing the content of the couplet to be observed through it. Since the couplet carrying plate 5 sandwiches the couplet between itself and the main back plate 1, the couplet receives better protection. Furthermore, during the upward sliding of the couplet between the two frame strips 4, the couplet carrying plate 5 provides an additional limiting function in the direction of the main back plate 1, effectively pressing the couplet tightly against the main back plate 1, thus further preventing bending, wrinkling, or other deformation that may occur during sliding installation. In other embodiments, the couplet can also be placed on the surface of the couplet carrying plate 5 facing away from the main back plate 1.

[0036] In this embodiment, the couplet carrying plate 5 is a thin acrylic sheet with a certain degree of bending performance. This design allows the couplet carrying plate to be slightly bent even when the lower end of the couplet's main back panel is higher than the length of the couplet and the carrying plate 5, enabling it to slide upwards between the two frame strips 4 from the lower end of the main back panel. In other embodiments, other plastic sheets can be used. When there is no situation where the lower end of the couplet's main back panel is low above the ground, a rigid plastic sheet can also be used as the couplet carrying plate 5.

[0037] In this embodiment, the couplet is only secured to the upper edge of the adhesive layer, thus fixing it to the couplet carrying plate 5 only at its top. Since the lower end is ultimately secured by the second clamping member 3, and the couplet is limited by the side border strips 4, the stability of the couplet is well ensured by fixing only the upper end. This minimizes the use of the adhesive layer, making it easier and more convenient to replace the couplet on the couplet carrying plate 5. In this embodiment, double-sided adhesive is used; in other embodiments, common adhesives such as liquid or solid glue can also be used. Alternatively, in some other embodiments, grooves are provided on the couplet carrying plate 5 to facilitate the insertion and fixation of the couplet's edges, avoiding the use of adhesive and making the replacement process cleaner and more convenient. However, this type of implementation is more suitable for situations where the couplet is placed between the transparent couplet carrying plate 5 and the couplet main back plate 1. In other embodiments, other suitable and stable fixing methods that can be conceived by those skilled in the art, such as magnetic attraction, snap-fit ​​structure, electrostatic or negative pressure adsorption, can also be used to fix the couplet on one side of the couplet carrying plate 5. However, it is necessary to ensure that the couplet can stably cover the couplet carrying plate 5 during the sliding process of the couplet carrying plate 5 from bottom to top.

[0038] Furthermore, considering how to more effectively connect the couplet carrying plate 5 and the couplet to the two frame strips 4, thereby providing a better and more stable guidance for the up-and-down sliding process of the couplet carrying plate 5 and the couplet, please refer to the following: Figure 3On the opposing sides of the two frame strips 4, slots 41 parallel to the main back panel 1 of the couplet are provided. Each slot 41 has an opening at its bottom end. The two sides of the couplet carrying plate 5 in the width direction are slidably connected to the slots 41 of the frame strip 4 on the same side. The two sides of the couplet carrying plate 5 in the width direction can enter / exit the corresponding slots 41 through the corresponding openings. With this configuration, when the couplet carrying plate 5 and the couplet are slid between the two frame strips 4 from bottom to top, the two edges of the couplet carrying plate 5 enter the slots 41 on both sides through the openings. The slots 41 limit the movement of the couplet carrying plate 5, leaving only one degree of freedom for vertical movement, thus providing good guidance.

[0039] In this embodiment, the surface area of ​​the couplet paper is slightly larger than that of the couplet carrying plate 5. This means the edge of the couplet paper is outside the couplet carrying plate 5, and the edge of the couplet paper also enters the slots 41 on both sides through the open opening. Therefore, the slots also guide the sides of the couplet paper. This is suitable for situations where the couplet is only connected to the couplet carrying plate 5 at its top. Another embodiment where the surface area of ​​the couplet paper is the same as that of the couplet carrying plate 5 also has this technical effect. In other embodiments, the surface area of ​​the couplet paper is smaller than that of the couplet carrying plate 5, suitable for situations where the perimeter of the couplet paper is connected to the couplet carrying plate 5.

[0040] Considering production and installation costs, the frame strip 4 is best constructed using aluminum alloy profiles, and its final connection to the couplet's main back panel 1 should be detachable. Therefore, referring to... Figure 1 and Figure 3 Furthermore, each of the two side panels 4 has a mounting groove 42 parallel to the slot 41 on its opposite side. The two sides of the main back panel 1 in the width direction are detachably embedded in the mounting groove 42 on the same side, so as to achieve a detachable connection with the main back panel 1.

[0041] In this embodiment, the frame strip 4 is a narrow aluminum alloy profile with a slot 41 and a mounting groove 42, thus presenting a narrow frame design. This not only saves materials, but also minimizes the obstruction of the edges of the couplet after installation, thereby ensuring that the main content of the couplet is not covered.

[0042] Furthermore, it also includes: a box body 6, which has an opening on one side, allowing the upper ends of the main back panel 1 and the frame strip 4 to enter the box body 6 through the opening. The frame strip 4 abuts against the inner side of the box body 6 in the width direction of the carrying plate 5, and the first clamping member 2 is located inside the box body 6.

[0043] The box body 6 is a decorative component, but in the embodiment of the detachable frame strip 4 described above, the box body 6 can constrain and limit the frame strip 4 from both sides, thereby stabilizing the connection between the frame strip 4 and the main back panel of the couplet.

[0044] Furthermore, a photovoltaic panel is provided on the outer side of the box body 6, and a charging power supply is provided inside the box body 6. The photovoltaic panel is charged through an electrical connection to the charging power supply. A light strip groove parallel to the frame strip is opened on the inner side wall of the slot 41. A light strip is provided in the light strip groove, and one end of the light strip extends into the box body 6 and is electrically connected to the charging power supply.

[0045] With the above configuration, the light strip provides edge illumination for the couplets, enhancing their aesthetic appeal. The visually bright border also assists the user in inserting the couplet carrying plate 5. Furthermore, since the light strip groove 43 is located inside the groove 41, the light strip itself is not exposed to the outside, further improving the aesthetic effect and providing protection.

[0046] The photovoltaic panel in the above configuration can be installed on the front side of the housing 6 or on other outer surfaces of the housing. It is used by a rechargeable battery to provide a continuous power supply to the light strip. In some embodiments, by incorporating existing technologies such as timer relays and timer switches between the rechargeable battery and the light strip, the light strip is turned off during the day while the photovoltaic panel charges the rechargeable battery, and then turned on at night to be powered by the rechargeable battery.

[0047] In this embodiment, the groove 41 is as follows Figure 7 As shown, a light strip groove 43 is formed on the inner side of the slot 41 opposite to the upper surface of the couplet, and there is a gap between the inner side of the slot 41 opposite to the upper surface of the couplet and the two carrying plates 5. It is preferable to use aluminum alloy profile to make the frame strip 4, so as to form it in a low-cost manner. Figure 7 The structure in.

[0048] In other embodiments, the light strip groove 43 can also be set on the inner side of the groove 41 at other angles, so that the light strip set in the light strip groove 43 can form different auxiliary lighting effects according to the needs and the setting position.

[0049] Furthermore, the first clamping member 2 includes: a first fixing part 21, a first pressing part 22, and an elastic part 23. The first fixing part 21 is fixedly connected to the upper end of the main back plate 1 of the couplet. The first pressing part 22 is hinged to the first fixing part 21. The elastic part 23 is connected between the first fixing part 21 and the first pressing part 22. Under the elastic force of the elastic part 23, the first pressing part 22 can press against the side of the couplet carrying plate 5 away from the main back plate 1 of the couplet, thereby clamping the upper end of the couplet carrying plate 5 between the first pressing part 22 and the main back plate 1 of the couplet.

[0050] In this embodiment, as Figure 4As shown, the first fixing part 21 and the first pressing part 22 are both long strip-shaped plates parallel to the upper edge of the main back plate 1 of the couplet, and are located between the two and are hinged by a pivot. The elastic part 23 is a coil spring sleeved on the pivot and acts between the first fixing part 21 and the first pressing part 22. Under the elastic action of the coil spring, the first pressing part 22 presses against the main back plate 1 of the couplet, and the upper end of the couplet carrying plate 5 can carry the couplet and squeeze it between the first pressing part 22 and the main back plate 1 of the couplet, thereby clamping the upper edge of the couplet carrying plate 5 and the couplet.

[0051] In other embodiments, the first fixing part 21 and the first pressing part 22 may be arranged in other forms. For example, the first fixing part 21 and the first pressing part 22 may be plates parallel to the left and right sides of the main back plate 1 of the couplet. The left and right sides of the upper end of the couplet carrying plate 5 may be squeezed between the first pressing part 22 and the main back plate 1 of the couplet, thereby clamping the side edges of the couplet carrying plate 5 and the couplet.

[0052] In other embodiments, the first fixing part 21 and the first pressing part 22 may also be respectively provided on the front and rear sides of the couplet main back plate 1.

[0053] Furthermore, considering that in this embodiment, the stiffness of the couplet carrying plate 5 is relied upon to squeeze the couplet carrying plate 5 and the couplet between the first pressing part 22 and the couplet main back plate 1, in order to make this process more reliable, a guiding structure is needed for the squeezing movement of the couplet carrying plate 5. Therefore, specifically, referring to... Figure 4 The first pressing part 22 has a warped edge 221 on the side facing the bottom of the main back panel 1. The warped edge 221 warps away from the main back panel 1. The stiffness of the couple carrying plate 5 is configured to overcome the elastic force of the elastic part 23 under the guidance of the warped edge 221, so that the upper end of the couple carrying plate 5 can be squeezed between the first pressing part 22 and the main back panel 1. With this configuration, even if the inclination of the lower surface of the warped edge 221 provides a guiding effect for the couple carrying plate 5, the upper end of the couple carrying plate 5 can be squeezed between the first pressing part 22 and the main back panel 1 along the lower surface of the warped edge 221.

[0054] Furthermore, considering that the second clamping member 3 is located at the bottom end of the main back panel 1 of the couplet, that is, at the entrance where the couplet carrying plate 5 slides from bottom to top between the two side strips 4, the second clamping member 3 needs to be designed to avoid obstructing the couplet carrying plate 5 from sliding between the two side strips 4 when it is not clamping and fixing the lower end of the couplet carrying plate 5. Therefore, please refer to... Figure 1 , Figure 5 and Figure 6The second clamping member 3 includes a second fixing part 31, a second pressing part 32, and a locking mechanism. The second fixing part 31 is fixedly connected to the lower end of the main back plate 1 of the couplet, and the second fixing part 31 is located on the side of the main back plate 1 away from the couplet carrying plate 5. The second pressing part 32 is hinged to the lower end of the second fixing part 31, and the second pressing part 32 can rotate around the hinge point with the second fixing part 31 to the side of the main back plate 1 facing the couplet carrying plate 5. The locking mechanism is provided between the second fixing part 31 and the second pressing part 32. When the second pressing part 32 presses the couplet carrying plate 5 against the main back plate 1 of the couplet, the locking mechanism can lock the relative position of the second fixing part 31 and the second pressing part 32, thereby clamping the lower end of the couplet carrying plate 5 between the second pressing part 32 and the main back plate 1 of the couplet.

[0055] With the above configuration, when the lower end of the couplet carrying plate 5 is not clamped and fixed, the second fixing part 31 is located on the side of the couplet main back plate 1 away from the couplet carrying plate 5, and does not obstruct the movement path of the couplet carrying plate 5. The second pressing part 32 hangs down below the couplet main back plate 1 under the action of gravity, and does not obstruct the movement path of the couplet carrying plate 5. When the couplet carrying plate 5 moves into place, the second pressing part 32 can rotate around the hinge point with the second fixing part 31 to the side of the couplet main back plate 1 facing the couplet carrying plate 5 and lock the locking mechanism, thereby clamping and fixing the lower end of the couplet carrying plate 5.

[0056] To further optimize operational convenience, the locking mechanism includes a magnetic suction member 33. A mounting hole is provided at the lower end of the main back panel 1. A second fixing part 31 is located at one end of the mounting hole. The magnetic suction member 33 is fixedly connected to the side of the second fixing part 31 facing the main back panel 1 and is located within the mounting hole. When the second pressing part 32 presses the couplet carrying plate 5 against the main back panel 1, the magnetic suction member 33 can magnetically attract the second pressing part 32, thereby locking the relative position of the second fixing part 31 and the second pressing part 32. Thus, operational convenience is optimized through magnetic attraction. Furthermore, in this configuration, since the magnetic suction member 33 is embedded in the mounting hole, it does not obstruct the movement path of the couplet carrying plate 5.

[0057] In this embodiment, in order to control costs, both the second fixing part 31 and the second pressing part 32 are made of aluminum alloy material that is the same as the frame strip 4 profile. In order to enable the second pressing part 32 to be magnetically attracted by the magnetic attractor 33, the second pressing part 32 includes a plate body and an iron sheet. The plate body is hinged to the second fixing part 31, and the iron sheet is embedded in the plate body, so that the second pressing part 32 can be magnetically attracted by the magnetic attractor 33.

[0058] Furthermore, the outer diameter of the end of the magnetic attractor 33 facing the second pressing part is larger than the inner diameter of the mounting hole, and the outer diameter of the end of the magnetic attractor 33 facing the second fixing part 31 is smaller than the inner diameter of the mounting hole.

[0059] With the above configuration, the limiting end of the magnetic suction component, because its outer diameter is larger than the inner diameter of the mounting hole, can effectively prevent the magnetic suction component from falling off the mounting hole, ensuring that the main back plate 1 of the coupler is located between the second fixing part 31 and the end of the magnetic suction component facing the second pressing part 32. Meanwhile, the other end, because its outer diameter is smaller than the inner diameter of the mounting hole, can easily pass through the mounting hole to complete the initial positioning, reducing assembly difficulty.

[0060] In some embodiments, the gap between the magnetic component 33 and the inner wall of the mounting hole can be further eliminated by filling with elastic gaskets or sealant to prevent the magnetic component 33 from shaking during use and to improve the stability of the overall structure.

[0061] In other embodiments, the magnetic suction member 33 can be configured as a circular, square, or waist-shaped structure, as long as the outer diameter of the member facing the second pressing part is greater than the inner diameter of the mounting hole and the outer diameter of the member facing the second fixing part is smaller than the inner diameter of the mounting hole. In addition, the end of the magnetic suction member facing the second pressing part can be configured as a hemispherical, conical, or directly as a frustum with a larger outer diameter, which can also achieve the limiting effect. Those skilled in the art can flexibly choose according to the appearance design requirements of the coupler frame.

[0062] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
