Description

Technical Field

[0001] This utility model relates to the field of opening and closing curtain technology, specifically to a splicing track assembly and an opening and closing curtain. Background Technology

[0002] Manually operated curtains (or manually sliding curtains), as a new type of curtain, typically include the following basic structure: a track, curtain slats for mounting the fabric, trolleys for moving the slats within the track, and a pull cord or operating rod. Users pull the pull cord or operating rod to move the curtain slats and trolleys along the track, thus achieving the coordinated opening or closing of multiple curtain slats. Currently, there are two main structural types of manually operated curtains on the market: non-extendable and extendable. However, both structures have revealed certain limitations in practical applications, affecting the product's performance and user experience.

[0003] For non-retractable curtains, their structure is fixed and their size is not adjustable. Therefore, they must be custom-made according to the user's actual window size before sale and installation. This customization model not only increases manufacturing costs and extends delivery time, but also results in low product adaptability due to a lack of versatility, making it difficult to meet the diverse installation needs of different users and limiting its market promotion and application scope.

[0004] While retractable blinds solve the size compatibility issue to some extent, several shortcomings remain. First, although the tracks of these products have a certain range of adjustment, this range is still limited by the structural design, with clearly defined minimum and maximum applicable size ranges. Therefore, a good match cannot be achieved in certain special situations. Second, the retractable structure has design limitations. The top of the extended inner track often cannot be flush with the top of the outer track, causing light leakage at the top of the track and affecting the light-blocking effect. Furthermore, the stepped difference in height between the inner and outer tracks makes the overall appearance less smooth and aesthetically pleasing, reducing the product's visual quality and decorative appeal. Finally, retractable structures typically involve more moving parts and connecting mechanisms, resulting in a relatively complex overall structure. This not only increases assembly difficulty and failure rate but also affects the long-term stability and reliability of the product.

[0005] Therefore, there is an urgent need in this field to develop a curtain solution that offers more flexible and convenient size adjustment and easier assembly, in order to overcome the above problems and enhance the overall product competitiveness. Utility Model Content

[0006] The purpose of this utility model is to overcome the defects of the prior art and provide a spliced ​​track assembly and opening and closing curtain, which can solve the problems of non-adjustable track size or limited adjustment range in the prior art, as well as light leakage, complex structure and high assembly difficulty of telescopic tracks.

[0007] To achieve the above and other objectives, this utility model is implemented through the following technical solution: As a first aspect, this utility model proposes a splicing track assembly, including a track, including a trolley groove and a splicing groove, wherein the trolley groove is used for slidingly installing the trolley; the shape of the splicing groove matches the splicing strip; the splicing strip is inserted into the splicing groove from the side for seamlessly splicing two adjacent sections of the track.

[0019] 2. The slot of this utility model is set on the non-front and rear end surfaces of the track to keep the front and rear end surfaces of the track clean;

[0020] 3. This utility model provides a first and second rib that are perpendicular to each other at the corner of the splicing groove, which can limit the splicing strip and ensure that the splicing strip fits tightly with the splicing groove, thereby ensuring that the two sections of track are flush after splicing.

[0021] 4. The third rib of this utility model is used to press the stepped structure of the splicing strip to prevent the splicing strip from deforming due to unilateral force when tightening it;

[0022] 5. The design of the end cap of this utility model can ensure that when the curtain is retracted, the side of the curtain and the side of the end cap remain flush.

[0023] 6. The design of the positioning column of this utility model allows the end cap to be fitted onto the track and slide on the track to adjust the installation position to adapt to the fine adjustment of the overall size. The length of the positioning column is the adjustable distance of the end cap.

[0024] 7. The distance from the positioning post to the screw hole of the side cover is less than the length of the trolley, which ensures that no matter how the distance between the end cover and the track is adjusted, the trolley will always slide within the track and will not fall between the track and the positioning post.

[0043] Please combine Figure 1-6The interlocking track assembly includes a track 10, splicing strips 20, and end caps 30. The track 10 is provided with a trolley groove 11, a splicing groove 12, and a snap-fit ​​groove 13. At least one trolley groove 11 is provided, its shape matching the trolley 40 for sliding installation, allowing the trolley 40 to slide linearly within the groove 11. The splicing groove 12 is used for side mounting of the splicing strip 20; its opening 121 is located on the non-front and rear end faces of the track 10 to keep the front and rear end faces of the track 10 clean. The snap-fit ​​groove 13 is used to snap the end cap 30 in place. The splicing strip 20 enables seamless splicing of adjacent track sections 10. The end caps 30 are fitted onto the outer ends of the two outermost tracks 10 to seal the left and right end faces of the interlocking track assembly, providing dust protection and aesthetic appeal.

[0044] Specifically, two splicing grooves 12 can be provided, with a side projection shape approximately L-shaped, located on the front and rear sides of the track 10 respectively; the splicing groove 12 is a through groove passing through the left and right sides of the track 10, and its groove opening 121 is located at the top of the track 10. At the corners of the splicing groove 12, a vertically downward first rib 122 and a horizontally outward second rib 123 are provided to limit the splicing strip 20 and ensure a tight fit between the splicing strip 20 and the splicing groove 12, thereby ensuring that the two sections of track 10 are flush after splicing. A horizontally outward third rib 124 is provided at the groove opening 121 to press the stepped structure 222 of the splicing strip 20, preventing deformation of the splicing strip 20 due to unilateral force when tightening it.

[0045] like Figures 3-5 A first embodiment of the splicing strip 20 is shown. The splicing strip 20 is L-shaped, matching the shape of the splicing groove 12, and includes a vertical portion 21 and a horizontal portion 22. A first groove 211 is provided on the vertical portion 21, matching the second rib 123 of the splicing groove 12; a second groove 221 is provided on the horizontal portion 22, matching the first rib 122 of the splicing groove 12; a stepped structure 222 is provided on the horizontal portion 22, cooperating with a third rib 124. A protrusion 223 is formed between the second groove 221 and the stepped structure 222, and a screw hole 224 is provided on the protrusion 223 for locking the splicing strip 20 onto the track 10.

[0046] When it is necessary to splice the track 10, two splicing strips 20 provided in this embodiment are required to splice the two sections of track 10. During splicing, one end of the two splicing strips 20 is inserted into the two splicing slots 12 from the left / right side of one track 10, and the other end of the two splicing strips 20 is inserted into the two splicing slots 12 from the right / left side of another track 10. The positions of the track 10 and the splicing strips 20 are adjusted so that the two adjacent sections of track 10 are spliced ​​together. The left and right ends of the splicing strips 20 are locked onto the two sections of track 10 with screws in the screw holes 224. The best splicing effect can be achieved when the lengths of the two splicing strips 20 in the two sections of track 10 are approximately equal.

[0047] like Figure 6 and Figure 7 A second embodiment of the splicing strip 20 is shown. The splicing strip 20 is gate-shaped and includes two vertical portions 21 and one horizontal portion 22. Each vertical portion 21 is provided with a first groove 211, which matches the second rib 123 of the splicing groove 12. The horizontal portion 22 is symmetrically provided with two second grooves 222 and two stepped structures 223, which match the first rib 122 and the third rib 124 of the splicing groove 12, respectively. A screw hole 224 is provided in the middle of the horizontal portion 22 for locking the splicing strip 20 onto the track 10.

[0048] When it is necessary to splice the track 10, only one splicing strip 20 provided in this embodiment is needed to splice the two sections of track 10. During splicing, one end of the splicing strip 20 is inserted into two splicing slots 12 from the left / right side of one track 10 at the same time, and the other end of the splicing strip 20 is inserted into two splicing slots 12 from the right / left side of another track 10 at the same time. The positions of the track 10 and the splicing strip 20 are adjusted so that the two adjacent sections of track 10 are spliced ​​together. The left and right ends of the splicing strip 20 are locked onto the two sections of track 10 with screws in the screw holes 224. The best splicing effect can be achieved when the length of the splicing strip 20 in the two sections of track 10 is approximately equal.

[0049] like Figure 8 As shown, the end caps 30 on the track 10 can be of two types: inner sleeve and outer sleeve. For ease of illustration, the figure shows one inner sleeve and one outer sleeve end cap 30 fitted at each end of the same track 10. However, in practical applications, the end caps 30 at both ends of the spliced ​​track assembly should be of the same type. Please refer to... Figure 13 The design of the end cap 30 ensures that when the curtain 50 is retracted, the side of the curtain 50 remains flush with the side of the end cap 30.

[0050] Specifically, Figure 9 A schematic diagram of a first embodiment (i.e., an outer jacket type) of the end cap 30 is shown. Please refer to... Figure 10The outer-type end cap 30 includes a sliding groove 31 and a positioning post 32. The sliding groove 31 cooperates with the track 10, specifically by wrapping the sliding groove 11 of the track 10 and engaging with the snap-fit ​​groove 13. This allows the end cap 30 to be fitted onto the track 10 and slide on the track 10 for adjustment of its installation position to accommodate fine-tuning of the overall machine size. After fine-tuning, the end cap 30 is secured to the track 10 with screws in the side cover screw holes 33 on the top of the end cap 30. The side projection of the positioning post 32 is T-shaped, and its position corresponds one-to-one with the sliding groove 11. One end of its length is fixed to the side of the end cap 30, and the distance from the other end to the side cover screw hole 33 is less than the length of the trolley 40. This ensures that regardless of how the distance between the end cap 30 and the track 10 is adjusted, the trolley 40 always slides within the track 10 and will not fall between the track 10 and the positioning post 32. The length of the positioning post 32 is the adjustable distance of the end cap 30.

[0051] Specifically, Figure 11 A schematic diagram of a second embodiment (i.e., inner sleeve type) of the end cap 30 is shown. Please refer to... Figure 12 The inner-sleeve end cap 30 includes a sliding groove 31 and a positioning post 32. The sliding groove 31 cooperates with the track 10, specifically by being embedded in the trolley groove 11 of the track 10 and engaging with the snap-fit ​​groove 13. This allows the end cap 30 to be fitted into the trolley groove 11 of the track 10 and to slide on the track 10 for adjustment of its installation position to accommodate fine-tuning of the overall machine dimensions. After fine-tuning, the end cap 30 is secured to the track 10 with screws in the side cover screw holes 33 on the top of the end cap 30. The side projection of the positioning post 32 is T-shaped, and its position corresponds one-to-one with the trolley groove 11. One end of its length is fixed to the side of the end cap 30, and the distance from the other end to the side cover screw hole 33 is less than the length of the trolley 40. This ensures that regardless of how the distance between the end cap 30 and the track 10 is adjusted, the trolley 40 always slides within the track 10 and will not fall between the track 10 and the positioning post 32. The length of the positioning post 32 is the adjustable distance of the end cap 30.

[0052] In summary, the splicing track assembly and opening / closing curtain provided by this utility model can be seamlessly spliced ​​according to the user's needs by selecting the required size of track and splicing strip. The overall structure of the splicing track assembly is simple. During the splicing operation, it is only necessary to insert the two ends of the splicing strip into the adjacent two track sections from the side to achieve precise seam positioning. The fastening is completed by screw tightening. Not only is the size adjustment more flexible and convenient and the assembly difficulty lower, but the end faces of the spliced ​​multi-section track are also flush, eliminating the risk of light leakage. It can solve the problems of non-adjustable track size or limited adjustment range in the prior art, as well as the problems of light leakage, complex structure and high assembly difficulty of telescopic tracks.

[0053] Therefore, this utility model effectively overcomes the various shortcomings of the prior art and has high industrial application value. The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit this utility model. Any person skilled in the art can modify or change the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or changes made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
