Description

Technical Field

[0001] This utility model relates to the field of furniture technology, specifically to a bamboo curtain fixing frame that does not require drilling. Background Technology

[0002] Traditional bamboo blind mounting brackets require drilling holes in the wall or window frame using tools like electric drills, followed by securing with expansion screws. This method is not only cumbersome, requiring specialized tools and experience, but also causes irreversible damage to the mounting surface. For painted walls, drilling can lead to cracking and peeling of the surrounding coating; for tiled walls, it may cause the tiles to shatter; and for wooden window frames, it weakens their structural strength. More importantly, once the spacing of the drilling points is determined, it cannot be flexibly adjusted. If the installation location is changed later, and the actual dimensions of the mounting surface (such as a window frame or archway) do not match the pre-set dimensions, the existing bamboo blind bracket will be unsuitable for the new installation needs, severely limiting its applicability. Furthermore, if the drilling position deviates or the bamboo blind style needs to be changed or the installation position adjusted later, the original holes are difficult to repair, affecting aesthetics and creating safety hazards, causing significant inconvenience to users. Utility Model Content

[0003] This utility model provides a non-drillable bamboo curtain fixing frame to solve the problems mentioned in the background art.

[0004] To achieve the above-mentioned objectives, this utility model adopts the following technical solution:

[0005] A non-drillable bamboo curtain fixing frame includes a main body and at least one set of locking components. The main body is an elongated base, and the locking components include a mounting base fixed to the main body, a fastener movable along the length of the main body, a pushing member fixedly connected to the fastener, and a locking member linked to the pushing member. When an operating force is applied to the fastener, the fastener converts the operating force into a driving force that moves the pushing member along the length of the main body, thereby driving the locking member to extend or retract relative to the main body.

[0006] Furthermore, the mounting base is a U-shaped connecting plate structure including a first side plate, a second side plate, and a base plate connecting the two side plates. The base plate has mounting holes for cooperating with the main body, so that the mounting base can be detachably fixed to the main body by bolts.

[0007] Furthermore, the upper surface of the main body is provided with a track groove along the length direction, and the locking member is an L-shaped plate structure integrally formed by a vertical plate and a horizontal plate. The horizontal plate is embedded in the track groove, and the track groove defines and guides the locking member to move in a straight line along the length direction of the main body.

[0008] Furthermore, the connection between the base plate of the mounting base and the first side plate and the second side plate is provided with reinforcing ribs.

[0009] Furthermore, the fastener is a wing bolt, which has an axially extending threaded section and an integrally formed handle portion.

[0010] Furthermore, the outer circumferential surface of the axial end of the fastener is provided with a groove.

[0011] Furthermore, the first side plate of the mounting base has a first through hole along the thickness direction, and the first through hole is through to accommodate the threaded section of the fastener.

[0012] Furthermore, the pushing member is an integrally formed U-shaped plate-like component, including a first side wall, a second side wall, and a connecting wall connecting the bottom ends of the two side walls, and a second through hole is provided on the connecting wall.

[0013] Furthermore, the slot end of the fastener passes through the second through hole, and the slot is fitted with a stop member, which is an elastic retaining ring.

[0014] Furthermore, an anti-slip sleeve is embedded and fixed on the outer surface of the vertical plate of the locking member.

[0015] The advantages of this utility model over the prior art are as follows:

[0016] In this design, the main body adopts an integrally molded elongated support base. The track groove on its upper surface provides a precise installation positioning benchmark for the mounting base, ensuring its positional stability along the length of the main body, and also limits the horizontal movement path of the pushing and locking components, ensuring the linear trajectory and accuracy of the locking action. In the U-shaped connecting plate structure of the mounting base, the reinforcing ribs at the connection between the bottom plate and the side plate, and the reinforcing plate extending towards the main body, enhance the load-bearing capacity through structural reinforcement, preventing the locking components from loosening and falling off. The fasteners are configured as wing bolts, and the manually operated handle, in conjunction with the threaded transmission of the fastening nut, realizes the horizontal driving force output. The circumferential constraint of the nut on the threaded section prevents the fastener from deflecting or shaking. The pushing component transmits force through the contact between the abutment plate and the locking component surface. The guide wall of the second side plate of the mounting base constrains the pushing component to move only in a straight line along the length of the main body, ensuring linkage accuracy. The elastic rubber anti-slip sleeve on the outer surface of the locking component, by squeezing and adhering to the mounting surface, converts the mechanical locking force into a high-friction surface contact force, effectively resisting lateral loads such as bamboo curtain pulling and wind. The synergistic effect of the above structures effectively solves the problems of traditional bamboo curtain fixing frames, such as reliance on drilling tools, irreversible damage to the installation surface, inability to adjust the fixing spacing, and narrow applicability. It achieves the technical effects of drilling-free installation, flexible spacing, convenient and efficient operation, and stable and reliable fixing. Attached Figure Description

In all examples shown and discussed herein, any specific values ​​should be interpreted as exemplary rather than limiting. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following figures denote similar items; therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0030] This invention addresses the shortcomings of existing bamboo curtain fixing frames, such as reliance on drilling tools for installation, damage to the mounting surface, inability to adjust the fixing spacing, and narrow applicability. It provides a drill-free bamboo curtain fixing frame by employing a main body with a track groove, combined with a locking assembly including a mounting base, fasteners, a pushing component, a locking component, and an elastic anti-slip sleeve. This achieves drill-free installation, flexible adjustment of the locking spacing, convenient operation, and stable fixing, effectively solving the defects of existing bamboo curtain fixing frames. The embodiments of this drill-free bamboo curtain fixing frame are described in detail below with reference to the accompanying drawings.

[0031] like Figure 1 and Figure 2As shown, this utility model discloses a non-drilling bamboo curtain fixing frame 10, including a main body 100 and a locking component 200. The main body 100 is a one-piece molded rectangular strip-shaped support base with a certain thickness (e.g., 3cm-5cm) to ensure the rigidity of the support for the locking component 200 and the bamboo curtain. The main body 100 has two sets of threaded holes 110 symmetrically formed at both ends along its length, serving as assembly interfaces for the locking component.

[0032] In other embodiments (not shown in the figures), the main body 100 can adopt a telescopic or segmented structure. Specifically, the main body 100 consists of an outer tube and an inner tube, which can slide relative to each other along the length direction and are fixed in position by locking screws, buckles, or elastic pins to adapt to installation areas of different widths. Alternatively, the main body 100 can also be assembled from several independent segments by interlocking or tenon joints, thereby facilitating transportation and storage, while improving the adaptability and flexibility of the bamboo curtain fixing frame.

[0033] Please refer to the corresponding documents as well. Figure 1 , Figure 3 and Figure 4 The locking components 200 are configured as two sets with completely identical structures. Each set of locking components 200 is provided with a mounting base 210. The mounting base 210 is configured as an integrally formed U-shaped connecting plate structure, including a first side plate 211 and a second side plate 212 arranged in parallel with each other, and a base plate 213 connecting the first side plate 211 and the second side plate 212. The base plate 213 is provided with mounting holes 2131 that are adapted to the threaded holes 110, so that the mounting base 210 can be detachably fixed to the main body 100 by bolt structure.

[0034] In other embodiments (not shown in the figures), the fixing method between the mounting base 210 and the main body 100 is not limited to threaded or bolted connections; a quick-release snap-fit ​​structure can also be used. Specifically, the main body 100 has a limiting snap-fit ​​in its track groove that cooperates with the mounting base 210. The user can lock or release the mounting base 210 simply by pressing or sliding, without the need for tools. This quick-release structure not only reduces the difficulty of disassembly and assembly but also facilitates quick adjustment of the position of the locking component 200 as needed, improving the overall ease of use.

[0035] Please continue reading. Figure 4The base plate 213 is integrally formed with reinforcing ribs 214 at the connection between the base plate 213, the first side plate 211, and the second side plate 212. These ribs enhance the support strength of the mounting base 210 and prevent the locking assembly 200 from loosening and falling off. In addition to the reinforcing ribs 214, a reinforcing plate 215 extends from the mounting base 210 along the length of the base plate 213 toward the main body 100. The lower end face of the reinforcing plate 215 abuts against the upper surface of the main body 100. This surface contact support further enhances the load-bearing capacity of the mounting base 210, preventing the locking assembly 200 from loosening or falling off due to stress.

[0036] Please refer to the following: Figure 3 , Figure 4 and Figure 5 The locking assembly 200 includes a fastener 220, which is configured as a wing bolt. One end of the fastener extends integrally to form a handle portion 221 for manual operation, and a threaded section 222 is machined on the outer peripheral surface of the middle portion. The other end is recessed along the outer peripheral surface of its axial end to form an annular groove 223. The first side plate 211 of the mounting base 210 has a first through hole 2111 along its thickness direction. The first through hole 2111 is a circular through hole with an inner diameter slightly larger than the outer diameter of the threaded section 222 of the fastener 220. The threaded section 222 of the fastener 220 passes through the first side plate 211. The mounting base 210 also includes a fastening nut 216, which is fixed to the side surface of the first side plate 211 near the second side plate 212 by a snap-fit ​​method and is coaxially arranged with the first through hole 2111. Its inner wall thread engages with the threaded section 222 of the fastener 220. By engaging the threaded nut 216 with the threaded section 222, when the handle 221 is rotated, the fastener 220 can move horizontally along its own axial direction (i.e., the thickness direction of the first side plate 211); at the same time, the fastener 216 forms a circumferential constraint on the threaded section 222, restricting the fastener 220 from deflecting or swaying about a non-axial direction during movement.

[0037] like Figure 3 and Figure 6 As shown, the locking assembly 200 also includes a pusher 230 and a locking member 240 fixedly connected to the pusher 230. The pusher 230 is an integrally formed U-shaped plate structure, consisting of a first sidewall 231 and a second sidewall 232 arranged relatively parallel to each other, and a connecting wall 233 connecting the bottom ends of the two. The connecting wall 233 has a second through hole 2331 along its thickness direction. This second through hole 2331 is a circular through hole, and its inner diameter is adapted to the fastener 220 to have a slot 223 (see...). Figure 5 The outer diameter of one end is used for the slot end of fastener 220 to pass through. After the slot end of fastener 220 passes through the second through hole 2331, it passes through the stop member 217 (see...). Figure 5The stop 217 is preferably an elastic retaining ring, which forms an axial limiting constraint. The maximum outer diameter of the stop 217 is greater than the inner diameter of the second through hole 2331, thereby restricting the fastener 220 from disengaging along its own axial direction away from the pusher 230. Even if the fastener 220 is subjected to rotational torque or axial tension, the stop 217 can still ensure that the fastener 220 and the pusher 230 maintain an axial connection by engaging with the slot 223, avoiding separation due to excessive rotation or force, and ensuring the structural integrity and operational reliability of the locking assembly 200 during adjustment and use.

[0038] See Figure 3 , Figure 4 and Figure 6 The second side plate 212 of the mounting base 210 is provided with a square opening 2121. The width of the square opening 2121 is adapted to the distance between the first side wall 231 and the second side wall 232 of the pusher 230, and the height is adapted to the overall thickness of the pusher 230. It allows the U-shaped opening end of the pusher 230 to pass through along the length direction parallel to the main body 100, and at the same time reserves space for the subsequent horizontal movement of the pusher 230. On the inner side wall of the square opening 2121, corresponding to the contact position of the first side wall 231 and the second side wall 232 of the pusher 230, two opposing guide walls 2122 are integrally extended along the thickness direction of the second side plate 212. The distance between the two guide walls 2122 is in clearance fit with the distance between the outer walls of the first side wall 231 and the second side wall 232 of the pusher, and their extension direction is consistent with the length direction of the main body 100. The function of the guide wall 2122 is as follows: on the one hand, by fitting and constraining the two side walls of the pusher 230, the pusher 230 can only move in a straight line in the horizontal direction parallel to the length direction of the main body 100; on the other hand, it forms a radial limit on the pusher 230 to prevent it from deflecting or shaking in the direction perpendicular to the length of the main body during movement or under force, so as to ensure the linkage accuracy between the pusher 230 and the locking member 240, thereby ensuring the locking reliability of the locking assembly 200 on the bamboo curtain.

[0039] like Figure 3 and 6As shown, the ends of the first sidewall 231 and the second sidewall 232 of the pusher 230 away from the connecting wall 233 both extend integrally towards the side close to the locking member 240, forming an abutment plate 234 in a direction perpendicular to the surfaces of the first sidewall 231 and the second sidewall 232. The outer surface of the abutment plate 234 forms a surface contact abutment with the outer surface of the locking member 240. When the fastener 220 moves in a horizontal direction parallel to the length direction of the main body 100, its horizontal driving force is transmitted to the pusher 230. The pusher 230 transmits this driving force synchronously to the locking member 240 through the surface contact force transmission of the abutment plate 234, so that the locking member 240 moves towards the main body 100 (see Figure 1) in the same horizontal direction as the pusher 230. Figure 8 The device can extend outwards to adjust the locking position, or retract and reset in the opposite horizontal direction to unlock the device.

[0040] like Figure 1 , Figure 2 and Figure 3 As shown, a track groove 120 is formed on the upper surface of the main body 100 along its length direction. This track groove 120 connects with the base plate 213 of the mounting base 210 (see Figure 213). Figure 4 The locking element 240 is an L-shaped plate structure, including a vertical plate 241 connected to the abutment plate 234 of the pusher 230, and a horizontal plate 242 extending from the bottom of the vertical plate 241 toward the main body 100. The width and thickness of the horizontal plate 242 are adapted to the width and depth of the track groove 120, allowing the horizontal plate 242 to be embedded within the track groove 120. The extension direction of the track groove 120 precisely defines the horizontal movement path of the horizontal plate 242 during locking and unlocking. During operation, the horizontal plate 242 slides within the track groove 120, ensuring that the locking element 240 can only stably extend or retract along a predetermined straight trajectory parallel to the length direction of the main body 100. It effectively prevents any skew, twisting or radial sway of the locking component 240 during movement, significantly improving the reliability and positioning accuracy of the locking action.

[0041] See Figure 7 An anti-slip sleeve 250 is embedded and fixed on the outer surface of the vertical plate 241 of the locking component 240. The anti-slip sleeve 250 is made of elastic rubber through one-piece injection molding. When the fastener 220 is tightened, the anti-slip sleeve 250 forms a tight fit with the installation surface (wall, window frame, etc.) through elastic compression. Utilizing the high friction characteristics between the rubber material and the contact surface, the mechanical locking force of the locking component 240 is converted into surface contact friction force, which can effectively resist the lateral load generated by the pulling of the bamboo curtain, wind, etc., and prevent the fixing frame from slipping along the main body, thereby ensuring the stability of the installation positioning.

[0042] In other embodiments (not shown in the figures), to enhance the friction between the locking member 240 and the mounting surface, the anti-slip sleeve 250 may be omitted. Instead, an anti-slip texture may be provided on the outer surface of the locking member 240. For example, microstructures such as longitudinal ribs, transverse ribs, intersecting diamond patterns, regular convex dots, or sawtooth convex teeth may be formed on the surface of the vertical plate 241. The texture may be continuous or discontinuous, and its height, spacing, and shape may be selected or adjusted according to the material of the mounting surface and friction requirements. The anti-slip texture may be formed directly on the metal or plastic surface by means of molding, stamping, rolling, sandblasting, shot peening, or laser etching. Alternatively, the texture may be formed on the substrate surface first, followed by surface hardening or coating with a wear-resistant coating to improve durability. As an alternative embodiment, a replaceable rough pad or adhesive microtextured patch may be attached to the texture. The above-described anti-slip textured embodiment can be used alone or in conjunction with the aforementioned anti-slip sleeve 250 to enhance the friction between the locking member 240 and the mounting surface and improve the stability of the fixation.

[0043] The preferred embodiments provided by this utility model can be operated through the following methods:

[0044] First, the main body 100 is placed against the pre-set area of ​​the mounting surface such as the window frame or wall. The butterfly handle 221 of the fastener 220 is rotated, and the threaded section 222 of the fastener engages with the threaded fastening nut 216 of the mounting base 210 to drive the pusher 230 to move horizontally along the guide wall 2122 of the second side plate 212 towards the mounting surface. This drives the locking member 240 to move synchronously until the anti-slip sleeve 250 is compressed and undergoes elastic deformation, thus tightly fitting the mounting surface. Through the high friction characteristics of the rubber material and the contact surface, the mechanical locking force of the locking member 240 is converted into surface contact friction force, completing the hole-free fixing. If it is necessary to adjust the installation position or disassemble, the butterfly handle 221 is rotated in the opposite direction to retract the pusher 230 and the locking member 240 towards the inside of the main body 100, thereby releasing the adhesion constraint between the anti-slip sleeve 250 and the mounting surface, achieving convenient adjustment and non-destructive disassembly.

[0045] In summary, this utility model achieves the following technical effects:

[0046] The main body 100 adopts an integrally formed elongated support base. The track groove 120 on its upper surface provides a precise installation positioning reference for the mounting base 210, ensuring its positional stability along the length of the main body, and also limits the horizontal movement path of the pushing component 230 and the locking component 240, ensuring the linear trajectory and accuracy of the locking action. In the U-shaped connecting plate structure of the mounting base 210, the reinforcing rib 214 at the connection between the bottom plate 213 and the side plate, and the reinforcing plate 215 extending towards the main body, enhance the load-bearing capacity through structural reinforcement and prevent the locking component 200 from loosening and falling off. The fastener 220 is configured as a wing screw. The bolt, with its manually operated handle 221 engaging with the threaded transmission of the fastening nut 216, delivers horizontal driving force. The nut's circumferential constraint on the threaded section prevents the fastener 220 from deflecting or wobbling. The pushing member 230 transmits force through surface contact with the locking member 240 via the abutment plate 234. The guide wall 2122 of the second side plate 212 of the mounting base constrains the pushing member to move linearly only along the length of the main body, ensuring linkage accuracy. The elastic rubber anti-slip sleeve 250 on the outer surface of the locking member 240, by pressing against the mounting surface, converts the mechanical locking force into a high-friction surface contact force, effectively resisting lateral loads such as bamboo curtain pulling and wind. The synergistic effect of these structures effectively solves the problems of traditional bamboo curtain fixing frames relying on drilling tools, irreversible damage to the mounting surface, inability to adjust the fixing spacing, and narrow applicability. It achieves the technical effects of drill-free installation, flexible spacing adaptation, convenient and efficient operation, and stable and reliable fixing.
