Description

Technical Field

[0001] This utility model relates to the field of curtain technology, and more specifically to a fast horizontal curtain structure. Background Technology

[0002] Currently, some horizontal blinds rely on beaded chains for raising and lowering control. For example, the Roman blind head disclosed in CN208957598U uses beaded chains to rotate an internal shaft, and a planetary gear structure reduces speed, achieving a labor-saving effect. Meanwhile, existing technologies also disclose blinds that do not require beaded chains for control. For example, the curtain transmission mechanism of a cordless blind disclosed in CN215859915U uses an internal coil spring to balance the weight of the blind, allowing the operator to directly control its raising and lowering by pulling the blind.

[0003] However, the aforementioned existing technologies still have some drawbacks. Curtains controlled by beaded chains require gears to adjust the transmission ratio in order to make the chain easier to pull. This results in slow curtain raising and lowering speeds, requiring a considerable amount of time to fully raise or lower the curtains, which is inconvenient. While cordless systems allow for quick manual adjustment of the curtains, they also present challenges for tall windows, where it's difficult to adjust the curtains to higher positions by hand, and for shorter individuals, reaching higher sections of the curtains is also difficult, presenting further inconvenience. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the present invention provides a quick horizontal curtain structure, which can be quickly adjusted by pulling beads, making it convenient to use. When the height is suitable, the height of the curtain can also be directly controlled by hand, increasing the flexibility of use.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a quick-release horizontal curtain structure, comprising a curtain box and a curtain body. A cord winder is installed inside the curtain box, and a transmission rod for transmitting power is threaded through the cord winder. A spring energy storage box and a quick-release head are connected to the transmission rod. The quick-release head includes a rotatable ball bearing wheel, a first transmission component, and a second transmission component. One end of the first transmission component is circumferentially fixed to the ball bearing wheel, and the other end is provided with a transmission plate A. One end of the second transmission component is provided with a transmission plate B adapted to the transmission plate A, and the other end is fixedly connected to the transmission rod. A coil spring for storing energy is installed inside the spring energy storage box. When the curtain body moves downwards, the coil spring deforms and stores energy.

[0006] The present invention is further configured such that: the first transmission member is provided with a connecting cavity, an internal gear structure is provided in the connecting cavity, and a gear rod is provided on the ball puller that is inserted into the connecting cavity and meshes with the internal gear structure.

[0007] The present invention is further configured such that the transmission plate A and the transmission plate B are configured as interlocking arc-shaped structures, with a gap between them.

[0008] The present invention is further configured such that: a damping spring is provided between the first transmission member and the second transmission member, one end of the damping spring is fixed on the transmission plate A, and the other end abuts against the end of the transmission plate B.

[0009] The present invention is further configured such that: the quick-acting head includes a housing and a connecting cylinder, the housing and the connecting cylinder are circumferentially fixed, the connecting cylinder is disposed through the middle, and the first transmission component is rotatably disposed inside the connecting cylinder.

[0010] The present invention is further configured such that the housing and the connecting cylinder are circumferentially fixed through a gear meshing structure.

[0011] The present invention is further configured such that: a circumferentially fixed washer is provided inside the housing, the washer being disposed through the middle, and the second transmission component is rotatably disposed inside the washer.

[0012] The present invention is further configured such that: a groove is provided on the outer circumferential surface of the washer, and a protrusion is provided in the housing at the position corresponding to the washer; the groove and the protrusion engage to achieve circumferential fixation of the washer and the housing.

[0013] The present invention is further configured such that: the spring energy storage box includes a first rod and a second rod, the first rod rotates synchronously with the transmission rod, and a coil spring is wound around the second rod, the outer end of the coil spring being fixedly connected to the first rod.

[0014] In summary, this utility model has the following beneficial effects:

[0015] This invention features a quick-acting head that allows the curtains to be raised and lowered quickly via an internal transmission mechanism. It also incorporates a spring energy storage box for added assistance, making it easier to pull the curtains, especially when pulling them up.

[0016] At the same time, the structural design of this utility model allows users to control the raising and lowering of the curtains not only by using the beaded chain but also by directly controlling the curtain body by hand. When the height is suitable, the curtains can be controlled by hand, and when the height is high, the beaded chain can be used to control the curtains, making it more flexible and convenient to use.

[0025] The present invention will be further described in detail below with reference to the accompanying drawings.

[0026] This embodiment discloses a quick-release horizontal curtain structure, such as... Figure 1-7 As shown, the curtain box includes a curtain box 1 and a curtain body 2. A cord winder 11 is installed inside the curtain box 1. A transmission rod 12 for transmitting power is threaded through the cord winder 11. A spring energy storage box 3 and a quick-acting stop 4 are connected to the transmission rod 12. A cord is wound around the cord winder 11 and connected to the curtain body, so that the transmission rod 12 can drive the curtain body to rise and fall when it rotates. The spring energy storage box 3 and the quick-acting stop 4 are used to control the transmission rod 12. For details, refer to... Figure 3-4The quick-acting head 4 includes a rotatable ball bearing wheel 41, a first transmission component 42, and a second transmission component 43. One end of the first transmission component 42 is circumferentially fixed to the ball bearing wheel 41, and the other end is provided with a transmission plate A421. One end of the second transmission component 43 is provided with a transmission plate B431 that is compatible with the transmission plate A421, and the other end is fixedly connected to the transmission rod 12. The spring energy storage box 3 is provided with a coil spring 33 for energy storage. When the curtain body moves downward, the coil spring 33 deforms and stores energy. Through the above structure, the pull bead wheel 41 and the transmission rod 12 are directly driven without deceleration, making the control of the transmission rod 12 by the pull bead 10 quick. When the curtain body 2 is lowered, since the curtain body 2 itself has a certain weight, the transmission rod 12 can be easily controlled to rotate by the pull bead 10. At this time, the coil spring 33 in the spring energy storage box 3 deforms and stores energy under the power of the curtain body 2 and the pull bead pulled by hand. When the pull bead 10 drives the transmission rod 12 to lift the curtain, the power provided by the hand disrupts the balance between the coil spring 33 and the curtain body 2, causing the coil spring 33 in the spring energy storage box 3 to release the previously stored energy, thereby playing a role in assisting and maintaining the effortless pulling of the pull bead 10. In this way, although the quick stop head 4 does not have a deceleration mechanism to save effort, it can still maintain the effortless driving of the curtain body 2 by relying on the assistance of the spring energy storage box 3. Meanwhile, since the ball bearing wheel 41 of the quick-release head 4 and the transmission rod 12 are in a direct transmission relationship, the curtain body 2 can also be directly held by hand for up and down adjustment. When the curtain body 2 is pulled down, the spring energy storage box 3 can store energy. When the curtain body 2 is lifted, the internal coil spring 33 releases energy to keep the curtain suspended and stable. If the quick-release head 4 has a deceleration mechanism, controlling the transmission rod through the ball bearing wheel is effortless, but conversely, driving the ball bearing wheel through the transmission rod is very strenuous, so the curtain cannot be directly pulled by hand. However, this application, through structural adjustment, allows the curtain body 2 to be controlled by the ball bearing or directly by hand, making adjustment faster and more convenient. When the height is suitable, the curtain body can be directly adjusted, while when the height is high and it is difficult to operate by hand, the ball bearing can be used for control, making the usage scenarios more flexible and versatile.

[0027] For further details, please refer to the specific structure. Figure 4 The first transmission component 42 is provided with a connecting cavity 5, and an internal gear structure is provided inside the connecting cavity 5. The ball wheel 41 is provided with a gear rod 6 that is inserted into the connecting cavity 5 and meshes with the internal gear structure. Through the above structure, the first transmission component 42 achieves direct transmission with the ball wheel 41, and the two achieve synchronous rotation.

[0028] Furthermore, refer to Figure 5The transmission plates A421 and B431 are designed as interlocking arc-shaped structures with a gap between them. Through this structure, when the first transmission component 42 rotates, the cooperation between transmission plates A421 and B431 drives the second transmission component 43 to rotate. The purpose of the gap is to allow for some tolerance in the transmission between the two, so that when the hand initially pulls the bead, it can easily rotate the first transmission component 42 slightly before the bead tightens and drives the second transmission component 43 to rotate, improving the user experience and preventing the bead from always being in a very tight and heavy state.

[0029] As another embodiment, refer to Figure 6 A damping spring 7 can be provided between the first transmission member 42 and the second transmission member 43. One end of the damping spring 7 is fixed to the transmission plate A421, and the other end abuts against the end of the transmission plate B431. Specifically, a cavity is provided in the transmission plate A421, and one end of the damping spring 7 is inserted into the cavity for fixation, while the other end of the damping spring 7 abuts against the opposite end of the transmission plate B431. The end abutting against the damping spring 7 corresponds to the rotation direction when the curtain body moves downward. In this way, when the curtain body moves downward, it needs to overcome the elastic force of the damping spring 7 first, further ensuring the stability of the curtain body and preventing the curtain body from falling due to its own weight. It can also reset the position between the first transmission member 42 and the second transmission member 43, maintain the gap between them, and thus maintain the pulling feel.

[0030] Furthermore, refer to Figure 3-4 The quick-acting head 4 includes a housing 44 and a connecting cylinder 45. The housing 44 and the connecting cylinder 45 are circumferentially fixed, and the connecting cylinder 45 is through-hole disposed in the middle. The first transmission member 42 is rotatably disposed inside the connecting cylinder 45. The connecting cylinder 45 provides support for the first transmission member 42. At the same time, the housing 44 and the connecting cylinder 45 are circumferentially fixed through a gear meshing structure, which ensures that the connecting cylinder 45 will not rotate when the first transmission member 42 rotates.

[0031] Furthermore, referring to the same Figure 3-4 A circumferentially fixed washer 441 is provided inside the housing 44, with the washer 441 having a through-hole in its center. The second transmission member 43 is rotatably mounted inside the washer 441. The washer 441 is used to support the rotation of the second rotating member 43. At the same time, a groove 8 is provided on the outer circumferential surface of the washer 441, and a protrusion 9 is provided inside the housing 44 at a position corresponding to the washer 441. The groove 8 and the protrusion 9 engage to achieve circumferential fixation between the washer 441 and the housing 44, ensuring that the washer 441 will not rotate when the second rotating member 43 rotates.

[0032] Furthermore, refer to Figure 7The spring energy storage box 3 has a specific structure including a first rod 31 and a second rod 32. The first rod 31 and the transmission rod rotate synchronously through gears. A coil spring 33 is wound around the second rod 32, and the outer end of the coil spring 33 is fixedly connected to the first rod 31. When the curtain body 2 is pulled down, driving the transmission rod 12 to rotate, the coil spring 33 will wrap around the first rod 31 to accumulate elastic force. When the curtain body 2 is pulled up, the coil spring 33 releases the elastic force, driving the first rod 31 to rotate, thereby assisting the rotation of the transmission rod 12.

[0033] It should be noted that the curtain body in the attached drawings of this embodiment is an example of a honeycomb curtain, but this embodiment can be applied to various horizontal curtains, all of which can realize the rapid raising and lowering control of the curtain, and can also meet the requirements of using beaded cords to control the raising and lowering of the curtain or, like cordless curtains, directly controlling the raising and lowering of the curtain by hand.

[0034] The above description is only a preferred embodiment of the present utility model and is 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.
