Description

Technical Field

[0001] This utility model relates to the field of curtain technology, specifically to a curtain angle adjustment structure and a screen curtain. Background Technology

[0002] Patent CN202537073U discloses a pulley-track type screen curtain, comprising a screen curtain body consisting of an upper track, a curtain, and a lower track, and an upper beam. The lower part of the upper beam, corresponding to the screen curtain body, has one or more tracks. The inner cavity of each track contains one or more pulley assemblies and limiting blocks. Both ends of the upper track are connected to the pulley assemblies for transmission. Furthermore, the accompanying drawings of the patent disclose locking parts on both sides of the upper track. The distance between the two locking parts is not adjustable. This means that when the angle of the curtain needs to be changed, the distance between the two tracks must be adjusted. However, an integrated double track cannot adjust the distance between the two tracks. Additionally, for a split-track double track, disassembly and reassembly are required, which is more cumbersome. Utility Model Content

[0003] The technical problem this invention aims to solve is the difficulty in adjusting the angle of the curtain.

[0004] This utility model solves the above-mentioned technical problems through the following technical solution: a curtain angle adjustment structure, including at least two slides, a curtain top rod connected between the two slides, a ball bearing connected between the curtain top rod and the corresponding slide, the ball bearing including a sliding part and a rotating part, the sliding part being slidably connected to the corresponding slide, the sliding part being rotatably connected to the rotating part, the curtain top rod having at least three mounting holes arranged in a straight line, and at least one of the rotating parts being detachably connected to the corresponding mounting hole.

[0005] The technical advantage of this solution is that by detachably connecting at least one rotating part to the corresponding mounting hole, the distance between the two rotating parts in the slat top rod changes. Since the distance between the two tracks is fixed and the rotating part and the sliding part are rotatably connected, after one of the two rotating parts is detachably installed from one mounting hole to the other, the corresponding ball bearing slides a certain distance on one track, and the corresponding other ball bearing also slides a certain distance on the other track. The angle of the slat top rod changes, and there is no need to disassemble the track, which is more convenient.

[0006] Furthermore, both ends of the slat top rod are provided with connecting portions, and each connecting portion includes at least two mounting holes.

[0007] The technical advantage of this solution is that, by setting the connecting parts, when adjusting the position of the rotating part on the slat top rod, the rotating parts in the two connecting parts can be adjusted simultaneously, ensuring that the two ends of the slat top rod remain relatively balanced and ensuring the smooth operation of the curtain fabric.

[0008] Furthermore, in each of the connecting portions, the spacing between two adjacent mounting holes is equal.

[0009] The technical advantage of this solution is that the spacing between adjacent mounting holes is equal in each connection, so as to fix the adjustment angle of the curtain.

[0010] Furthermore, the top rod of the curtain slat has a receiving cavity, which communicates with the mounting hole, and the receiving cavity has an mounting opening facing upwards.

[0011] The technical advantages of this solution are as follows: by setting up the receiving cavity, the rotating part is installed in the receiving cavity, providing installation space for the rotating part and facilitating its installation. Furthermore, the installation opening of the receiving cavity is set to face the slide rail so that the rotating part is not easy to fall off after being installed in the receiving cavity. The installation opening of the receiving cavity is set to face upward so that the rotating part is not easy to fall off after being installed in the receiving cavity.

[0012] Furthermore, the top rod of the curtain slat is connected to the rotating part by bolts and nuts, and the bolts pass through the rotating part and are connected to the corresponding mounting holes.

[0013] The technical advantage of this solution is that the bolts and nuts are detachable, so that when the curtain angle needs to be adjusted, the bolts and nuts can be quickly removed and installed from the original mounting hole to another mounting hole to complete the adjustment of the curtain angle. Furthermore, the bolts pass through the rotating part to ensure a stable connection between the curtain top rod and the rotating part during operation.

[0014] Furthermore, at least a portion of the nut extends into the mounting hole.

[0015] The technical advantage of this solution is that the nut extends into the mounting hole so that the connection between the nut and the bolt is located inside the mounting hole, allowing the bolts to be installed from both sides of the curtain top rod, and ensuring that the stud is not exposed, thus forming an internally concealed bolt.

[0016] Furthermore, the two slides are located on the same track or on the main track and the auxiliary track, respectively.

[0017] Furthermore, a rope connects two adjacent balls within one of the slides.

[0018] The technical effect of this solution is that the rope causes the ball bearing in one of the slides to slide along the adjacent ball bearings, and ultimately causes multiple curtain top rods to move together in the corresponding slides.

[0019] Further optimization involves detachably connecting a curtain fabric to the top rod of the curtain slat.

[0020] The technical advantage of this solution is that the curtain can be detachably connected to the top rod of the curtain slats. The detachable method will not damage the curtain itself, thus ensuring the integrity of the curtain.

[0021] This utility model also provides a screen curtain. The above-mentioned curtain angle adjustment structure further includes a driving device, which drives the ball bearings to move within the slide rail.

[0022] Based on common knowledge in the field, the above-mentioned preferred conditions can be combined arbitrarily to obtain various preferred embodiments of this utility model. Attached Figure Description

[0035] 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. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present utility model or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0036] It should be noted that in the claims and specification of this patent, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one" does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes the element.

[0037] This utility model discloses a curtain angle adjustment structure, such as Figure 1-11 As shown, it includes at least two slides, with a curtain top rod 1 connecting the two slides. A ball bearing 10 is connected between the curtain top rod 1 and the corresponding slide. The ball bearing 10 includes a sliding part 2 and a rotating part 3. The sliding part 2 is slidably connected to the corresponding slide, and the sliding part 2 is rotatably connected to the rotating part 3. The curtain top rod 1 has at least three mounting holes 4 arranged in a straight line, and at least one rotating part 3 is detachably connected to the corresponding mounting hole 4.

[0038] Preferably, two tracks are used, with a fixed distance between them, and the top rod 1 of the curtain slat is as follows. Figure 9 As shown in (a) and (b), the slat top rod 1 is inclined between two slide rails, and a ball bearing 10 is connected between the slat top rod 1 and the two slide rails. The sliding part 2 and the rotating part 3 are rotatably connected so that the rotating part 3 can rotate relative to the sliding part 2 when adjusting the angle of the slat top rod 1.

[0039] The rotating part 3 and the corresponding sliding part 2 are rotatably connected, while the sliding part 2 is slidably connected within the slide rail and cannot rotate. When it is not necessary to adjust the angle of the slat top rod 1, the slat top rod 1 connects the corresponding ball bearings 10 on the two slide rails, so that the rotating part 3 cannot rotate relative to the sliding part 2.

[0040] When adjusting the angle of the slat top rod 1, it is only necessary to adjust one of the rotating parts 3 from one of the mounting holes 4 to another. At this time, at least three mounting holes 4 are used, and the distance between the corresponding two ball bearings 10 will change. Specifically, the rotating part of the ball bearing 10 in one of the tracks can be disengaged from the mounting hole. At this time, the slat top rod 1 can rotate and move the ball bearing 10 in that track. Then, the rotating part of the ball bearing 10 is installed and engaged with another mounting hole, and the ball bearing 10 in the other track does not move.

[0041] Before adjustment Figure 9 As shown in (a), the screen curtain has a large tilt angle. When it is necessary to adjust the angle of the curtain top rod 1, the rotating part 3 is moved from one of the mounting holes 4 in the curtain top rod 1 to the other mounting hole 4. Specifically, the rotating part 3 is first disassembled from one of the mounting holes 4, and then the rotating part 3 and the sliding part 2 slide together in the slide rail. At this time, the curtain top rod 1 can rotate a certain angle. Then the rotating part 3 is assembled into the other mounting hole 4. After adjustment, it is as shown in (a). Figure 9 As shown in (b), the screen curtain has a smaller tilt angle, resulting in a better screen curtain effect.

[0042] Multiple mounting holes 4 are arranged in a straight line, which is either parallel to or along the horizontal axis D of the top rod 1 of the curtain slat.

[0043] Specifically, both ends of the curtain top rod 1 are formed with connecting parts, and each connecting part includes at least two mounting holes 4.

[0044] By designing the connecting parts, when adjusting the position of the rotating part 3 on the slat top rod 1, the rotating parts 3 within both connecting parts can be adjusted simultaneously, ensuring that the two ends of the slat top rod 1 remain relatively balanced and guaranteeing smooth operation of the slats. For example... Figure 3 As shown, the left and right ends of the slat top rod 1 have multiple mounting holes 4. That is, when adjusting the angle of the slat top rod 1, the rotating part 3 at the left end of the slat top rod 1 is moved from one of the mounting holes 4 at the left end to another mounting hole 4 at the left end, and the rotating part 3 at the right end of the slat top rod 1 is moved from one of the mounting holes 4 at the right end to another mounting hole 4 at the right end.

[0045] Specifically, in each connecting part, the spacing between two adjacent mounting holes 4 is equal.

[0046] When the rotating part 3 is adjusted from the mounting hole 4 to the adjacent mounting hole 4, the adjustment angle of the screen curtain is fixed.

[0047] Specifically, the top rod 1 of the curtain slat has a receiving cavity 15, which is connected to the mounting hole 4. The receiving cavity 15 has an mounting opening, which is set upwards.

[0048] The cavity 15 provides an installation space for the rotating part 3, which can be installed into the cavity 15 (not shown in the figure) so that the cavity 15 restricts the position of the rotating part 3 and ensures the connection between the curtain top rod 1 and the rotating part 3.

[0049] like Figure 3 , 4 As shown, the mounting opening of the receiving cavity 15 is oriented upwards so that the rotating part 3 is not easily dropped after being installed in the receiving cavity 15.

[0050] Specifically, the top rod 1 of the curtain slat is connected to the rotating part 3 by bolts 5 and nuts 6, and the bolts 5 pass through the rotating part 3 and are connected to the corresponding mounting holes 4.

[0051] The detachable connection of bolt 5 (thread not shown in the figure) and nut 6 allows for quick adjustment of the slat top rod 1 angle by disassembling bolt 5 and nut 6 and installing them from the original mounting hole 4 to another mounting hole 4. The corresponding rotating part 3 can be adjusted to mate with the other mounting hole 4 (adjusted via the sliding ball bearing 10). The bolt 5 passes through the rotating part 3 and connects to the corresponding mounting hole 4, ensuring a secure connection between the slat top rod 1 and the rotating part 3 during operation.

[0052] Specifically, at least part of the nut 6 extends into the mounting hole 4.

[0053] like Figure 10 As shown, the nut 6 can be a non-circular nut 6 with a cavity 11. This non-circular nut 6 is integrally T-shaped (thread not shown in the figure). By installing one end of the bolt 5 into the cavity 11 of the non-circular nut 6, the bolt 5 engages with the thread in the cavity 11, achieving quick assembly of the bolt 5 and the nut 6. The connection between the non-circular nut 6 and the bolt 5 is located within the mounting hole 4, allowing the bolt 5 and the non-circular nut 6 to be installed from both sides of the curtain top rod 1 respectively. Furthermore, the bolt 5 does not penetrate the non-circular nut 6, ensuring that the stud portion of the bolt 5 is not exposed, forming an internally concealed bolt 5, which is more aesthetically pleasing.

[0054] like Figure 5 As shown, bolt 5 is installed on the right side of the curtain top rod 1, and rotating part 3 is installed on the left side of the curtain top rod 1. At this time, nut 6 passes through rotating part 3, and bolt 5 enters the cavity 11 in the irregular nut 6 and is threadedly connected to nut 6.

[0055] Nut 6 can also be a regular nut 6 (not shown in the figure). The regular nut 6 has a cavity 11 that passes through both ends, which is a through hole. The bolt 5 passes through the mounting hole 4, and part of the bolt 5 extends out of the regular nut 6. The installation steps are relatively simple. The bolt 5 can be passed through the mounting hole 4 first, and then the regular nut 6 can be screwed on. When disassembling, the regular nut 6 can be quickly unscrewed to complete the disassembly, which is relatively convenient.

[0056] Specifically, the two slides are located on the same track or on the main track 8 and the auxiliary track 9 respectively.

[0057] The two slide rails can be installed on an integrated double rail, which is molded in one piece, making it easy to process and install. Alternatively, the two slide rails can be installed on two separate tracks, either a main track 8 or a secondary track 9. The main track 8 and the secondary track 9 can be installed separately, and the distance between the two tracks can be adjusted appropriately before installation.

[0058] Specifically, a rope 14 connects two adjacent ball bearings 10 within one of the slides.

[0059] A rope 14 is installed between adjacent beads 10. The rope 14 is elastic so that the adjacent beads 10 can move together. This ensures that when one bead 10 slides on the slide rail during the operation of the screen curtain, the adjacent beads 10 can also move. Thus, under the action of the top rod 1 of the curtain slat, multiple screen curtains move together.

[0060] Specifically, a curtain fabric 7 is detachably connected to the top rod 1 of the curtain slats.

[0061] A curtain fabric 7 is detachably connected to the top rod 1 via Velcro. Specifically, a first Velcro fastener 12 is fixedly connected to the top rod 1, and a second Velcro fastener 13 is provided on the curtain slat. The first and second Velcro fasteners 12 are connected by adhesive. This detachable connection method does not damage the curtain fabric 7 itself, ensuring its integrity. When the user needs to change the angle of the curtain fabric 7 after a period of use, the user can tear off the first and second Velcro fasteners 12 and 13, temporarily separating the top rod 1 from the curtain fabric 7, facilitating subsequent adjustment of the angle of the top rod 1.

[0062] Furthermore, the first Velcro 12 is provided with connecting holes 16 corresponding to the number of mounting holes 4, and the connecting holes 16 are arranged opposite to the mounting holes 4.

[0063] By opening a connection hole 16 on the first Velcro 12 and passing the bolt 5 through the connection hole 16, the angle of the curtain 7 can be adjusted without disassembling the curtain 7, which is quite convenient.

[0064] A screen curtain includes the aforementioned curtain angle adjustment structure, and also includes a driving device that drives a ball bearing to move within a slide rail. Preferably, the driving device is a motor-driven belt, with the ball bearing fixed to the belt, thus achieving the purpose of driving the ball bearing to move on the slide rail.

[0065] Other embodiments of the present invention will readily occur to those skilled in the art upon consideration of the specification and practice of the disclosure herein. This application is intended to cover any variations, uses, or adaptations of the present invention that follow the general principles of the present invention and include common knowledge or customary techniques in the art not disclosed herein. The specification and examples are to be considered exemplary only, and the true scope and spirit of the present invention are indicated by the following claims.
