Technical Field
[0001] This utility model relates to the field of curtain technology, specifically to a drilling-free installation structure and a curtain. Background Technology
[0002] Roman blinds are a common type of curtain, consisting of multiple parallel strips of fabric. When the curtain cord is pulled, the fabric strips can be folded into parallel layers, thus achieving the effect of blocking sunlight and protecting privacy. They are widely used in homes, offices, conference rooms, and many other places.
[0003] Some existing curtain products, such as Roman blinds, require drilling holes in the wall and then fixing the upper beam bracket of the curtain with bolts and other parts. Drilling is troublesome, installation is time-consuming and laborious, and bolt holes are left on the wall, damaging the wall and affecting its integrity. Utility Model Content
[0004] To address at least one of the aforementioned problems, this utility model provides a drill-free installation structure, including an upper crossbeam support, a first mounting bracket, and a second mounting bracket. The first mounting bracket and the second mounting bracket are respectively disposed at both ends of the upper crossbeam support. A mounting screw is threaded onto the first mounting bracket, and a first fixing block is connected to the end of the mounting screw near the external first wall. The mounting screw is rotatable relative to the first fixing block. A first anti-slip pad is disposed on the side of the first fixing block near the first wall. The second mounting bracket is provided with a second fixing block and an elastic element. The second fixing block is slidably disposed on the second mounting bracket along its own axial direction. The elastic element is disposed on the second mounting bracket and the first fixing block. Between the second fixing blocks, a second anti-slip pad is provided on the side of the second fixing block closest to the external second wall. During installation, the elastic force of the elastic element drives the second fixing block to slide towards the side of the second wall, so that the second anti-slip pad abuts against the second wall. The mounting screw is rotated by external force, so that the mounting screw drives the first fixing block to slide towards the side of the first wall, so that the second mounting bracket approaches the second fixing block, and finally the second mounting bracket approaches the second fixing block and abuts against it, so that the first anti-slip pad is pressed against the first wall and the second anti-slip pad is pressed against the second wall, so that the upper crossbeam bracket is fixed between the first wall and the second wall.
[0005] This utility model features a drilling-free installation structure with a simple structure and low production cost. During installation, the second anti-slip pad is first placed against the second wall surface, and then the installation screw is rotated to make the second anti-slip pad press firmly against the first wall surface, thereby fixing the upper beam bracket between the first and second walls to complete the installation. No drilling is required in the wall surface, making installation more convenient.
[0006] Optionally, the elastic element is a compression spring, one end of the elastic element abuts against the second fixing block, and the other end of the elastic element abuts against the second mounting bracket; before installation, the elastic force of the elastic element causes the end of the second fixing block with the second anti-slip pad to extend out of the second mounting bracket.
[0007] Optionally, the second mounting bracket is provided with a first positioning post for mounting and positioning one end of the compression spring, and the second fixing block is provided with a second positioning post for mounting and positioning the other end of the compression spring. After installation, the first positioning post and the second positioning post abut against each other. The mounting screw is provided with an external thread, and the first mounting bracket is provided with an internal thread corresponding to the external thread.
[0008] Optionally, the first fixing block is provided with a plug-in post, and the mounting screw is provided with a plug-in groove for plugging into the plug-in post.
[0009] Optionally, the first mounting bracket is provided with a limiting block for restricting the rotation of the first fixed block.
[0010] Optionally, a planar bearing is provided between the mounting screw and the first fixing block.
[0011] Optionally, the first anti-slip pad is made of silicone, rubber, or foam, and the second anti-slip pad is made of silicone, rubber, or foam.
[0012] Optionally, one end of the mounting screw is provided with an adjusting block, the longitudinal section of the adjusting block is a regular polygon, and the adjusting block is provided with multiple grooves, the grooves being in the shape of a straight line.
[0013] Optionally, the mounting screw, the first fixing block, the first anti-slip pad, the second fixing block, and the second anti-slip pad are all placed on the lower side of the upper crossbeam bracket.
[0014] Compared to existing technologies, the drilling-free installation structure of this utility model is simple in structure and has low production costs. During installation, the second anti-slip pad is first placed against the second wall surface, and then the installation screw is rotated to make the second anti-slip pad press firmly against the first wall surface, thereby fixing the upper beam bracket between the first and second walls to complete the installation. No drilling is required in the wall surface, making installation more convenient. The elastic force of the elastic element helps to press the second anti-slip pad against the second wall surface, preventing the second anti-slip pad from slipping off the second wall surface due to insufficient pressing force during installation. Before installation, the elastic force of the elastic element causes the end of the second fixing block with the second anti-slip pad to extend out of the second mounting bracket, so that the extended part can press against the second wall surface during installation, reducing the installation difficulty. A plane bearing is provided between the installation screw and the first fixing block. The plane bearing has a strong axial load capacity, preventing structural damage and extending service life.
[0015] In addition, this utility model also provides a curtain, which includes the above-mentioned no-drill installation structure. This curtain also has the same beneficial effects of the above-mentioned no-drill installation structure, which will not be described in detail here. Attached Figure Description

Detailed Implementation
[0026] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.
[0027] In the description of this utility model, it should be understood that the terms "upper" and "lower" indicate the orientation or positional relationship based on the orientation or positional relationship when the product is in normal use.
[0028] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature.
[0029] See Figures 1-9 This utility model embodiment provides a drilling-free installation structure, including an upper crossbeam bracket 1, a first mounting bracket 2, and a second mounting bracket 3. The first mounting bracket 2 and the second mounting bracket 3 are respectively disposed at both ends of the upper crossbeam bracket 1. A mounting screw 4 is threaded onto the first mounting bracket 2. A first fixing block 5 is connected to one end of the mounting screw 4 near the external first wall surface 101. The mounting screw 4 can rotate circumferentially relative to the first fixing block 5. A first anti-slip pad 6 is adhered to the side of the first fixing block 5 near the first wall surface 101. A second fixing block 7 and an elastic element 8 are disposed on the second mounting bracket 3. The second fixing block 7 is slidably disposed on the second mounting bracket 3 along its own axial direction (i.e., horizontal direction). The elastic element 8 is disposed between the second mounting bracket 3 and the second fixing block 7. A second anti-slip pad 9 is adhered to the side of the second fixing block 7 near the external second wall surface 102. During installation, the elastic force of the elastic element 8 drives the second fixing block... 7. Slide the second anti-slip pad 9 to one side of the second wall 102 so that it abuts against the second wall 102. The elastic force of the elastic element 8 helps to tighten the second anti-slip pad 9 against the second wall 102, preventing the second anti-slip pad 9 from slipping off the second wall 102 due to insufficient clamping force during installation. Then, rotate the installation screw 4 by external force so that the installation screw 4 drives the first fixing block 5 to slide to one side of the first wall 101, so that the second mounting bracket 3 approaches the second fixing block 7. Finally, the second mounting bracket 3 approaches the second fixing block 7 and abuts against it, so that the first anti-slip pad 6 abuts against the first wall 101 and the second anti-slip pad 9 abuts against the second wall 102. After tightening, stop rotating the installation screw 4, so that the upper beam bracket 1 is fixed between the first wall 101 and the second wall 102, completing the installation of the curtain. The operation is convenient. When disassembling, simply rotate the installation screw 4 in the opposite direction (opposite to the direction of installation).
[0030] Specifically, the operating sequence during the installation of this no-drill installation structure is as follows: First, attach the second fixing block 7 to the second wall 102 (at this time, the second fixing block 7 is not in contact with the second mounting bracket 3; if the second fixing block 7 is in contact with the second mounting bracket 3 at this time, it will not affect the subsequent assembly steps). Then, rotate the installation screw 4 to move the first fixing block 5 away from the first mounting bracket 2, and finally drive the first anti-slip pad 6 to press against the first wall 101. Continue to rotate the installation screw 4, and the first fixing block 5 continues to push out. At this time, the second fixing block 5 and the second mounting bracket 3 move closer to each other, and finally the second fixing block 5 and the second mounting bracket 3 abut against each other. At this time, the installation screw 4 has no more space to extend. Continue to tighten the installation screw 4 to complete the installation, that is, the upper beam bracket 1 is fixed between the first wall 101 and the second wall 102 to complete the curtain installation.
[0031] This utility model features a drilling-free installation structure with a simple structure and low production cost. During installation, the second anti-slip pad is first placed against the second wall surface, and then the installation screw is rotated to make the second anti-slip pad press firmly against the first wall surface, thereby fixing the upper beam bracket between the first and second walls to complete the installation. No drilling is required in the wall surface, making installation more convenient.
[0032] See Figure 1 , Figure 3 , Figure 4 and Figure 6 The elastic element 8 is a compression spring, which has a simple structure and low production cost. One end of the elastic element 8 abuts against the second fixing block 7, and the other end of the elastic element 8 abuts against the second mounting bracket 3. Before installation, the elastic force of the elastic element 8 causes the end of the second fixing block 7 with the second anti-slip pad 9 to extend out of the second mounting bracket 3, so that the extended part can abut against the second wall surface 102 during installation, reducing the difficulty of installation. The second mounting bracket 3 is provided with a first positioning post 31 for mounting and positioning one end of the compression spring, and the second fixing block 7 is provided with a second positioning post 71 for mounting and positioning the other end of the compression spring. The compression spring is not easy to shift after installation and is reliable in use. After the curtain is installed, the first positioning post 31 and the second positioning post 71 abut against each other.
[0033] See Figure 5 , Figure 7 and Figure 8 The mounting screw 4 is provided with an external thread 401, and the first mounting bracket 2 is provided with an internal thread 201 corresponding to the external thread 401. By rotating the mounting screw 4, the mounting screw 4 can be displaced in the axial direction, thereby driving the first fixing block 5 to move synchronously in the axial direction. During installation, by rotating the mounting screw 4, the first fixing block 5 is driven to slide towards one side of the first wall 101, so that the first anti-slip pad 6 abuts against the first wall 101, thereby achieving the final installation purpose. The structure is reasonably designed and the operation is simple.
[0034] See Figure 1 , Figure 4 , Figure 5 , Figure 8 and Figure 9 The first fixing block 5 is provided with a plug-in post 501, and the mounting screw 4 is provided with a plug-in groove 402 for plugging into the plug-in post 501. The first fixing block 5 and the mounting screw 4 are assembled by plugging into each other, which is simple to assemble. The plug-in post 501 can rotate circumferentially in the plug-in groove 402 so that the mounting screw 4 can rotate circumferentially relative to the first fixing block 5, so that the mounting screw 4 will not drive the first fixing block 5 to rotate circumferentially during installation.
[0035] See Figure 5 , Figure 7 and Figure 9 The first mounting bracket 2 is equipped with a limiting block 202 to restrict the rotation of the first fixing block 5, so that the mounting screw 4 will not drive the first fixing block 5 to rotate circumferentially during installation. A plane bearing 10 is provided between the mounting screw 4 and the first fixing block 5, so that the mounting screw 4 can rotate smoothly relative to the first fixing block 5. During the installation process, the mounting screw 4 will drive the first fixing block 5 to slide towards one side of the first wall surface 101 so that the first fixing block 5 is pressed against the first wall surface 101. The greater the pressing force, the greater the friction between the first wall surface 101 and the first anti-slip pad 6 (making the installation more stable). The reaction force (resistance) of the first wall surface 101 on the first fixing block 5 will also be greater. The plane bearing 10 bears this reaction force. The plane bearing 10 has a strong axial load capacity, avoids structural damage, and has a long service life.
[0036] See Figures 1-3 The first anti-slip pad 6 is made of silicone, rubber, or foam, and the second anti-slip pad 9 is made of silicone, rubber, or foam. They have good anti-slip properties. The fixed installation effect of the upper beam bracket 1 is achieved by the friction between the first anti-slip pad 6 and the first wall 101 and the friction between the second anti-slip pad 9 and the second wall 102. The first anti-slip pad 6 and the second anti-slip pad 9 can also be made of other materials with good anti-slip properties.
[0037] See Figure 1 , Figure 4 , Figure 5 and Figure 8An adjusting block 403 is integrally provided at one end of the mounting screw 4. The longitudinal section of the adjusting block 403 is a regular polygon. In this embodiment, the adjusting block 403 is a regular hexagon. The adjusting block 403 can be rotated by tools such as an Allen wrench to complete the installation step. The adjusting block 403 is provided with multiple grooves 404. The grooves 404 are in the shape of a straight line. In this embodiment, each edge of the adjusting block 403 is provided with a groove 404. The adjusting block 403 can also be rotated by tools such as a flathead screwdriver. Specifically, the end of the flathead screwdriver is inserted into the groove 404, and then the adjusting block 403 is rotated by the flathead screwdriver. The adjustment method is diverse and flexible.
[0038] See Figures 1-6 The mounting screw 4, the first fixing block 5, the first anti-slip pad 6, the second fixing block 7, and the second anti-slip pad 9 are all placed on the lower side of the upper beam bracket 1. That is, the height of the mounting screw 4, the first fixing block 5, the first anti-slip pad 6, the second fixing block 7, and the second anti-slip pad 9 is lower than the height of the upper beam bracket 1. This avoids setting the above structures at the same horizontal height as the upper beam bracket 1, so that the above structures do not occupy too much horizontal space of the upper beam bracket 1. This is to reduce the first distance L between the curtain fabric 11 and the first wall 101 and the second distance M between the curtain fabric 11 and the second wall 102, thereby reducing light leakage. If the distance between the curtain fabric and the wall is too large, it will aggravate the problem of light leakage. In this embodiment, the upper beam bracket 1 is made of wood, and the first mounting bracket 2 and the second mounting bracket 3 are respectively fixed to the upper beam bracket 1 by bolts.
[0039] The drilling-free installation structure of this utility model is simple in structure and low in production cost. During installation, the second anti-slip pad is first placed against the second wall, and then the installation screw is rotated to make the second anti-slip pad press firmly against the first wall, thereby fixing the upper beam bracket between the first and second walls to complete the installation. No drilling is required in the wall, making installation more convenient. The elastic force of the elastic element helps to press the second anti-slip pad against the second wall, preventing the second anti-slip pad from slipping off the second wall due to insufficient pressing force during installation. Before installation, the elastic force of the elastic element causes the end of the second fixing block with the second anti-slip pad to extend out of the second mounting bracket, so that the extended part can press against the second wall during installation, reducing the installation difficulty. A plane bearing is provided between the installation screw and the first fixing block. The plane bearing has a strong axial load capacity, preventing structural damage and extending service life.
[0040] In addition, this utility model also provides a curtain, which includes the above-mentioned no-drill installation structure. This curtain also has the same beneficial effects of the above-mentioned no-drill installation structure, which will not be described in detail here.
