Description

Technical Field

[0001] This utility model relates to the field of curtain technology, and more specifically to a roller blind installation structure with a top beam that requires no drilling. Background Technology

[0002] In practical applications, to facilitate curtain installation and avoid damage to window frames and walls, many existing technologies offer drill-free curtain installation structures, such as Chinese patents with publication numbers CN215565610U and CN213175472U, which enable drill-free installation. However, current drill-free curtains directly apply the force against the wall to the circular tube or indirectly affect it, making some types of curtains unusable, such as motorized curtains and spring roller blinds without pull cords. A characteristic of these types of curtains is that the circular tube cannot withstand circumferential rotational resistance, but current technology prevents drill-free installation for these types. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a drill-free installation structure for roller blinds with an upper beam. The part that bears the top force is separated from the blind tube, so that the tube is not subject to circumferential rotational resistance, thus satisfying the drill-free installation of various blinds.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a drill-free installation structure for a roller blind with an upper beam, comprising an upper beam frame, the upper beam frame including a bearing cavity, an installation cavity, and side cover assemblies located on both sides, the side cover assemblies being snap-fitted into the bearing cavity and the installation cavity, at least one of the side cover assemblies on both sides having an ejector mechanism inside, the ejector mechanism being located within the bearing cavity, and the side cover assembly having an installation component located within the installation cavity and used for installing the tube body required for the blind.

[0005] The present invention is further configured such that: the ejection mechanism includes a telescopically movable top block, a driving mechanism and an ejection rod, the driving mechanism drives the ejection rod to extend outward, and when the ejection rod extends outward, it abuts against the top block.

[0006] The present invention is further configured such that: the top block has a spring component inside, and the spring component pushes the top block outward.

[0007] The present invention is further configured such that: the driving mechanism includes a rotating transmission cylinder, the ejector rod is coaxially disposed inside the transmission cylinder and the two are threadedly engaged; when the transmission cylinder rotates, the ejector rod achieves telescopic movement through the thread.

[0008] The present invention is further configured such that: the driving mechanism includes a rotating gear component, one end of which is connected to the outer circumferential surface of the transmission cylinder through a gear structure, and the other end is connected to the outside and is provided with a driving end for external tools to drive the rotation.

[0009] The present invention is further configured such that: a limiting block is provided on the ejector rod, and a limiting groove is provided on the top block; when the ejector rod abuts against the top block, the limiting block and the limiting groove engage to restrict the circumferential rotation of both.

[0010] The present invention is further configured such that: the ejector rod has a hollow square hole inside, and the top block has a square rod extending into the square hole of the ejector rod.

[0011] The present invention is further configured such that the mounting component and the side cover assembly are detachable.

[0012] The present invention is further configured such that the bearing cavity and the mounting cavity are arranged vertically and are integrally formed and manufactured.

[0013] The present invention is further configured such that an anti-slip part is provided on the outer end surface of the top block.

[0014] In summary, this utility model has the following beneficial effects: This utility model features an upper beam frame with a separate load-bearing cavity and an installation cavity. The corresponding ejection mechanism is located within the load-bearing cavity. Therefore, the force exerted on the window frame or wall acts on the ejection mechanism and the load-bearing cavity, without affecting the installation cavity. The installation cavity is then used to further install the curtain tube through the installation components. At this point, the tube does not bear circumferential rotational resistance, thus meeting the installation needs of various curtain tubes.

[0015] The ejection mechanism of this utility model is equipped with limiting blocks and limiting grooves on the ejection rod and the ejection block. After they come into contact, they lock together to prevent the ejection rod from loosening, making the ejected curtain more stable and reliable. Attached Figure Description

Detailed Implementation

[0023] The present invention will be further described in detail below with reference to the accompanying drawings.

[0024] This embodiment discloses a drill-free installation structure for a roller blind with an upper beam, such as... Figure 1-6 As shown, the device includes an upper beam frame 1, which comprises a bearing cavity 101, a mounting cavity 102, and side cover assemblies 2 located on both sides. The side cover assemblies 2 are engaged with the bearing cavity 101 and the mounting cavity 102. At least one of the side cover assemblies 2 has an ejector mechanism 3 located inside the bearing cavity 101. Each side cover assembly 2 has a mounting component 4 located inside the mounting cavity 102, which is used to install the tubing required for the curtain. For specific use, refer to... Figure 1 , Figure 1 The structure above indicates that the ejector mechanism 3 retracts, and during retraction, the upper beam frame is installed into the side window frames or side walls. Figure 1 The structure below indicates that the ejector mechanism 3 extends outward. At this time, the ejector mechanism 3 pushes against the window frame or wall, and the installation of the upper beam frame 1 is completed by relying on the pressure and friction of the ejection. With the above structure, the ejector mechanism 3 is installed in the bearing cavity 101, so that the force of pushing against the window frame or wall is concentrated in the bearing cavity 101 of the upper beam frame 1, without affecting the installation cavity 102. This makes the tube (not shown in the figure) for installing the curtain in the installation cavity 102, such as the round tube (i.e., the tube body) of the cordless curtain such as electric curtains and spring roller blinds, not subject to circumferential rotational resistance, thus making the rotation of the tube body smoother and making the no-drill installation structure applicable to this type of curtain, with better versatility.

[0025] Furthermore, refer to Figure 2-4The ejection mechanism 3 includes a telescopically movable top block 5, a drive mechanism 6, and an ejection rod 7. The drive mechanism 6 drives the ejection rod 7 to extend outward, and the ejection rod 7 abuts against the top block 5 after extending outward. The top block 5 can freely telescopically move relative to the ejection rod 7, which facilitates estimation of the extension distance during the measurement phase. Furthermore, a spring component 8 can be installed inside the top block 5, which pushes the top block 5 outward. This allows the top block 5 to be ejected in advance, enabling the ejection mechanism 3 to pre-fix the upper beam frame 1. During use, the user first overcomes the spring force to press the top block 5 inward, then installs the upper beam frame 1 into the sides of the window frame or wall. After releasing, the top block 5 is ejected again by the spring and abuts against the wall, achieving pre-fixation. When subsequently extending the ejection rod 7 outward for fixation, it is not necessary to hold the upper beam frame 1 by hand, making installation more convenient.

[0026] Furthermore, refer to Figure 3-4 The specific structure of the drive mechanism 6 includes a rotating transmission cylinder 601, and an ejector rod 7 coaxially disposed within the transmission cylinder 601 with a threaded connection between them. When the transmission cylinder 601 rotates, the ejector rod 7 extends and retracts via the thread. It is important to note that the ejector rod 7 needs to have its rotation restricted to allow it to extend and retract along the thread direction. In this embodiment, the structure for restricting the rotation of the ejector rod 7 is as follows: Figure 6 A hollow square hole is provided inside the ejector rod 7, and a square rod 10 extending into the square hole of the ejector rod 7 is provided on the top block 5. Through this structure, since the top block 5 cannot rotate, a square rod 10 extends from the top block 5 to cooperate with the square hole 11 in the middle of the ejector rod, thereby restricting the rotation of the ejector rod 7 and allowing it to only move axially. At the same time, the cooperation between the square hole 11 and the square rod 10 also increases the stability of the top block 5 during its telescopic movement, preventing the top block 5 from tilting and causing problems with smooth movement.

[0027] Furthermore, refer to Figure 4 The drive mechanism 6 includes a rotating gear 602. One end of the gear 602 is connected to the outer circumference of the transmission cylinder 601 via a gear structure, and the other end is connected to the outside and has a drive end 6021 for external tools to drive its rotation. Specifically, the gear 602 and the transmission cylinder 601 are driven by a bevel gear structure, and the drive end 6021 can be provided with an internal hexagonal structure, allowing tools such as wrenches to be inserted from the outside for rotation.

[0028] Furthermore, refer to Figure 4 and Figure 6The ejector rod 7 is equipped with a limit stop 701, and the top block 5 is equipped with a limit groove 501. When the ejector rod 7 abuts against the top block 5, the limit stop 701 and the limit groove 501 engage to restrict the circumferential rotation of both. In applications where good anti-loosening performance is required after installation and removal is generally unnecessary, this structure locks the ejector rod 7 and the top block 5, preventing the ejector rod 7 from rotating and thus eliminating the loosening problem of the threaded structure, ensuring the structural firmness and stability.

[0029] Furthermore, the mounting component 4 and the side cover assembly 2 are designed to be detachable. The mounting component 4 can be connected to the side cover assembly 2 by means of screws, etc., so as to achieve detachment and replacement. The mounting component 4 can be replaced according to the installation requirements of different curtain tubes, so that one upper beam frame can be adapted to different curtains and is convenient to use.

[0030] Furthermore, the supporting cavity 101 and the mounting cavity 102 are arranged vertically and are manufactured as a single piece. Specifically, the supporting cavity 101 and the mounting cavity 102 are manufactured as a single piece using aluminum profiles, while the mounting component 4 can be made of a thicker iron sheet with better strength. When the mounting component 4 is inserted into the mounting cavity 102 along with the side cover assembly 2, it can also play a role in increasing the structural strength and ensuring the installation stability of the curtain.

[0031] Furthermore, an anti-slip part 9 is provided on the outer end face of the top block 5. The anti-slip part 9 is made of materials such as rubber with high friction, and the high coefficient of friction makes it more secure when the top block comes into contact with the wall.

[0032] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the design concept of the present utility model should be included within the protection scope of the present utility model.
