Description

Technical Field

[0001] This utility model relates to the field of projection screen technology, and in particular to a simple screen. Background Technology

[0002] For retractable screens, a traction force is typically applied in the retracting / unrolling direction of the screen to flatten it. For example, when the screen is retracted vertically, the upper end of the screen is usually connected to the retracting mechanism, and the lower end is connected to a counterweight. After the screen is unrolled, the counterweight provides a force to the screen in the vertical direction, relying on the weight of the counterweight to attempt to flatten the screen. Additionally, screens are generally only fixed at one end, hanging freely. This often causes the screen to sway due to a slight breeze or footsteps, affecting the normal viewing experience.

Detailed Implementation

[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 skilled in the art without creative effort are within the protection scope of the present utility model.

Figure 2 This diagram shows the second structural schematic of the simplified screen in this invention. Figure 3 This diagram shows the third structural schematic of the simplified screen in this invention.

Figure 6 This diagram shows a second structural schematic of the mounting bracket in this invention. Figure 7 It shows Figure 6 Enlarged view of point B in the image. Figure 8 This diagram shows the third structure of the mounting bracket in this invention. Figure 9 It shows Figure 8 The enlarged view at point C shows that the simplified screen includes a mounting frame 100 and a screen 200. The mounting frame 100 includes multiple sets of mounting components 1, which are distributed along the edge of the screen 200. Each mounting component 1 includes a clamping plate 11 and at least one mounting bracket 12. One end of the mounting bracket 12 is provided with two symmetrically distributed L-shaped plates 121, which form a moving groove 122. The clamping plate 11 is provided with a snap-fit ​​part 111 that matches the moving groove 122. The snap-fit ​​part 111 is movably inserted into the moving groove 122. An installation area is formed between the end face of the moving groove 122 and the clamping plate 11, and the edge of the screen 200 is detachably installed in the installation area. In this embodiment, the mounting frame 100 has two sets of mounting components 1. When the mounting frame 100 has two mounting components 1, the two mounting components 1 are distributed along two opposite sides of the curtain 200, ensuring that the curtain 200 can be laid flat on the corresponding plane. Two L-shaped plates 121 are symmetrically distributed to form a moving groove 122. The moving groove 122 is used to engage the clamping plate 11, and the moving groove 122 restricts the position of the clamping plate 11, allowing it to be inserted into the mounting frame 100 along a preset direction, so that the clamping plate 11 and the mounting frame 100 can clamp the curtain 200. A certain space is left between the clamping plate 11 and the mounting bracket 12 to form the installation area. The edge of the curtain 200 is inserted into the corresponding installation area. When the edge of the curtain 200 is located in the corresponding installation area, the end face of the moving groove 122 and the clamping plate 11 simultaneously exert a clamping force on the edge of the curtain 200, fixing the edge of the curtain 200 in the corresponding position. This avoids the risk of the curtain 200 shaking, shifting, or falling off due to external forces, and helps to clamp the curtain 200 in the installation area, greatly enhancing the overall stability of the curtain 200 fixed on the plane, and providing users with a stable and reliable visual display effect.

[0031] It should be noted that when the mounting component 1 has one mounting bracket 12, the clamping plate 11 is inserted into the mounting bracket. One mounting bracket 12 is distributed along one side of the curtain 200, and another mounting bracket 12 is distributed along the opposite side of the curtain 200, so that both sides of the curtain 200 are subjected to a uniform force and are flatly stretched. When the mounting component 1 has two or more mounting brackets 12, the clamping plate 11 is simultaneously inserted into two or more mounting brackets 12. Taking this embodiment as an example, when a mounting component 1 has four mounting brackets 12, the four mounting brackets 11 are distributed along one side of the curtain 200. The four mounting brackets 12 of the other mounting component 1 are evenly distributed along the opposite side of the curtain 200, or the four mounting brackets 1 are distributed along one side of the curtain 200 according to actual needs. That is, the distance between the four mounting brackets can be different. Similarly, the four mounting brackets 12 of the other mounting component 1 can also be distributed at different distances along the opposite side of the curtain 200. This ensures that both sides of the curtain 200 are subjected to uniform force, which flattens it out and greatly enhances the overall stability of the curtain 200 fixed on the plane, providing users with a stable and reliable visual display effect.

[0032] Furthermore, the snap-fit ​​part 111 includes a guide block 1111 and a limiting block 1112. One end of the guide block 1111 is connected to the clamping plate 11, and the other end of the guide block 1111 is connected to the limiting block 1112. In this embodiment, the two sidewalls of the guide block 1111 abut against the ends of the two L-shaped plates 121 respectively. That is, the guide block 1111 is located in the guide groove formed between the ends of the two L-shaped plates 121. The guide block 1111 moves along the guide groove, which provides a clear movement path for the guide block 1111, allowing it to move only along a preset straight line direction. This ensures that the clamping plate 11 can be inserted into the mounting frame 100 along the preset direction, so that the clamping plate 11 and the mounting frame 100 can clamp the curtain 200.

[0033] Furthermore, the limiting block 1112 can be a rectangular or triangular block. When the limiting block 1112 is a rectangular block, it has four flat sides. When placed in the moving groove 122, all four sides can simultaneously contact the inner wall of the moving groove 122. This multi-faceted contact method allows the limiting block 1112 to be constrained in multiple directions within the moving groove 122, effectively preventing the limiting block 1112 from rotating or wobbling in the horizontal direction, thus achieving a stable fit. When the limiting block 1112 is a triangular block, the bottom surface of the triangular limiting block 1112 contacts the bottom plane of the moving groove 122, forming a stable support point. At the same time, the two inclined surfaces contact the sides of the moving groove 122, adding two more support points. This multi-point support method allows the limiting block 1112 to be constrained in multiple directions within the moving groove 122, maintaining a stable posture and preventing rotation or tilting.

[0034] Furthermore, a first buffer layer 1221 is provided on the end face of the moving groove 122, and a second buffer layer 1222 is provided on the side of the clamping plate 11 near the moving groove 122. The first buffer layer 1221 and the second buffer layer 112 clamp the corresponding edge of the curtain 200. In this embodiment, both the first buffer layer 1221 and the second buffer layer 112 are made of rubber. When the curtain 200 is located in the installation area, the first buffer layer 1221 abuts against the curtain 200, and the second buffer layer 112 also abuts against the curtain 200, clamping the curtain 200 in the installation area. When the first buffer layer 1221 and the second buffer layer 112 clamp the curtain 200, the first buffer layer 1221 exerts a force on the second buffer layer 112, while the second buffer layer 112 exerts a reaction force on the first buffer layer 1221, causing the first buffer layer 1221 and the second buffer layer 112 to exert a reaction force on the first buffer layer 1221. Both buffer layers 112 deform. The deformation of the first buffer layer 1221 increases the contact area between the first buffer layer 1221 and the edge of the curtain 200, thereby increasing the friction between the first buffer layer 1221 and the curtain 200. Similarly, the deformation of the second buffer layer 112 increases the contact area between the second buffer layer 112 and the edge of the curtain 200, thereby increasing the friction between the second buffer layer 112 and the curtain 200. The simultaneous increase in friction between the first buffer layer 1221 and the second buffer layer 112 and the curtain 200 reduces the risk of the curtain 200 falling off the installation area.

[0035] Furthermore, the mounting bracket 12 is provided with a plurality of fixing holes 123, which are distributed at preset positions. In this embodiment, the mounting bracket 12 is provided with two or more fixing holes 123. The distance between two adjacent fixing holes 123 can be equal or unequal. When the distance between two adjacent fixing holes 123 is equal, it ensures that the mounting bracket 12 can provide force simultaneously on the same plane, allowing the mounting bracket 12 to fit against the corresponding plane. When the distance between two adjacent fixing holes 123 is unequal, the unequal spacing of the holes can optimize the force transmission path, reduce the risk of local deformation, and ensure that the mounting bracket 12 is tightly fixed on uneven surfaces. Corresponding fixing screws can be screwed into the fixing holes 123 to fix the mounting bracket 12 to the corresponding wall or other plane. When there is one mounting bracket 12 located on the same edge of the screen 200, the mounting bracket 12 has two or more fixing holes 123, that is, eight fixing holes 123. The eight evenly distributed fixing holes 123 simultaneously provide clamping force, and the uniform clamping force can reduce the risk of the mounting bracket 12 shifting in the installation position due to excessive local force. When there are four mounting brackets 12 located on the same edge of the screen 200, the mounting bracket 12 has two fixing holes 123. The four mounting brackets 12 are distributed on the edge of the screen 200 according to the actual use scenario, that is, there are eight fixing holes 123 on the same edge of the screen 200. The eight fixing holes 123 simultaneously provide clamping force, and the uniform clamping force can reduce the risk of the mounting bracket 12 shifting in the installation position due to excessive local force.

[0036] Furthermore, the mounting component 1 is also provided with a plurality of fixing blocks 13, which are symmetrically distributed along the edge of the screen 200 based on the center of the screen 200. In this embodiment, the mounting component 1 is also provided with two fixing blocks 13, which are respectively located on two sides perpendicular to the mounting frame 12, that is, one fixing block 13 is located on one side, and the fixing block 13 is located at the midpoint of the side it is located on. The two fixing blocks 13 and the two sets of mounting components fix the screen 200 to the corresponding plane from the four edges of the screen 200. This layout makes the screen 200 more evenly stressed during fixing, effectively reducing the risk of the screen 200 shaking, shifting or falling off due to external forces (such as wind, human touch, etc.) during use, greatly enhancing the overall stability of the screen 200 fixed on the plane, ensuring that the screen 200 can always be kept in the preset position and state, and providing users with a stable and reliable visual display effect.

[0037] Furthermore, an F-shaped profile 124 is provided on the side of the mounting bracket 12 away from the clamping plate 11. The F-shaped profile 124 is fixedly connected to the mounting bracket 12, and the F-shaped profile 124 and the mounting bracket 12 form a fixing part with a hollow cavity. In this embodiment, the F-shaped profile 124 includes a first vertical plate 1241, a second vertical plate 1242, a first horizontal plate 1243, and a second horizontal plate 1244. The first horizontal plate 1243 is located between the first vertical plate 1241 and the second vertical plate 1242, and one end of the first horizontal plate 1243 is connected to one end of the first vertical plate 1241, and the other end of the first horizontal plate 1243 is connected to the second vertical plate 1242. The first horizontal plate 1243, the first vertical plate 1241, the second vertical plate 1242, and the mounting bracket 12 form a fixing part with a hollow wall. The presence of the hollow cavity not only reduces the weight of the entire installation structure but also improves the structural strength of the fixing part. Since the hollow cavity is surrounded by the solid parts of the mounting bracket 12 and the F-shaped profile 124, it forms a closed space that can effectively resist the action of external forces, which helps to reduce the risk of deformation of the fixing part and improve the service life of the mounting bracket 12.

[0038] Specifically, when the mounting assembly 1 has a mounting bracket 12, the F-shaped profiles 124 are distributed along the mounting bracket 12, and the length of the F-shaped profiles 124 is the same as the length of the mounting bracket 12. One side of the F-shaped profiles 124 is attached to the corresponding plane or wall surface, increasing the contact area between the mounting assembly 1 and the corresponding plane or wall surface, increasing the connection strength between the mounting assembly 1 and the plane or wall surface, thereby stably fixing one side of the curtain 200 to the corresponding plane or wall surface.

[0039] Furthermore, the mounting bracket 12 has multiple mounting protrusions 125 on the side away from the clamping plate 11, and the multiple mounting protrusions 125 have first connecting holes at the same position. In this embodiment, the mounting bracket 12 has two mounting protrusions 125 on the side away from the clamping plate 11, and the two mounting protrusions 125 have first connecting holes at the same position. Corresponding fixing connectors can be inserted into the first connecting holes to help fix the mounting bracket 12 to the corresponding wall or plane, which is beneficial to fixing the mounting bracket 12 in the corresponding position. Moreover, the two mounting protrusions 125 form a more stable support structure, effectively dispersing the force borne by the mounting bracket 12, reducing shaking or displacement caused by external forces, and making the mounting bracket 12 more stable and reliable.

[0040] Furthermore, a C-shaped fixing bracket 126 is provided on one side of the mounting bracket 12. The C-shaped fixing bracket 126 abuts against the sidewalls of the plurality of mounting protrusions 125, and the C-shaped fixing bracket 126 is provided with a second connecting hole 1261 that matches the first connecting hole. In this embodiment, the C-shaped fixing bracket 126 abuts against the sidewalls of the two mounting protrusions 125, and the C-shaped fixing bracket 126 is provided with a plurality of second connecting holes 1261 that match the first connecting hole. This facilitates the insertion of corresponding fixing components through the first connecting hole and the second connecting hole 1261, and connects the C-shaped fixing bracket 126 to the mounting bracket 12. When the mounting bracket 12 is subjected to external force, the mounting bracket 12 can distribute the force it bears to the C-shaped fixing bracket 126, reducing local stress concentration and helping to extend the service life of the mounting bracket 12.

[0041] Furthermore, the C-shaped fixing bracket 126 abuts against multiple mounting bosses 125. The C-shaped fixing bracket 126 is provided with multiple fixing components. Any of the fixing components passes through the corresponding first connection and the corresponding second connection hole 1261 to connect the mounting bracket 12 and the C-shaped fixing bracket 126. The multiple fixing components are evenly distributed at the connection between the C-shaped fixing bracket 126 and the mounting bracket 12, which can evenly transfer the load borne by the mounting bracket 12 to the C-shaped fixing bracket 126, and then further distribute it to the entire structure by the C-shaped fixing bracket 126, avoiding local stress concentration and helping to reduce the risk of deformation and damage caused by uneven stress.

[0042] Specifically, when the mounting assembly 1 has four mounting brackets 12, the four mounting brackets 12 are distributed along the C-shaped fixing frame 126. The four mounting brackets 12 can move along the C-shaped fixing frame 126 as needed. After the four mounting brackets 12 move to the corresponding positions, they are locked to the C-shaped fixing frame 126 using a fixing assembly. This helps to strengthen the connection between the mounting brackets 12 and the C-shaped fixing frame 126, ensuring that the C-shaped fixing frame 126 can also be fixedly connected to the mounting brackets 12 when it is fixedly connected to the corresponding wall or plane, thereby stably fixing one side of the curtain to the corresponding plane or wall.

[0043] In summary, this utility model, by setting a clamping plate and a mounting bracket on a simple screen, allows the edge of the screen to be detachably installed in the installation area formed between the clamping plate and the mounting bracket. The clamping plate and the mounting bracket simultaneously exert a clamping force on the edge of the screen, avoiding the risk of the screen shaking, shifting, or falling off due to external forces. This facilitates clamping the screen in the installation area, enhances the overall stability of the screen fixed on the plane, and provides users with a stable and reliable visual display effect.
