Description

Technical Field

[0001] This invention belongs to the field of curtain track technology, specifically relating to a curtain splicing track. Background Technology

[0002] Curtain tracks are a key component of curtain systems, enabling smooth opening and closing of curtains. With the diversification of architectural design and interior decoration, higher demands are placed on the functionality, aesthetics, and durability of curtain tracks. Traditional curtain tracks are mostly single-strip tracks; however, single-strip tracks are easily damaged during transportation and installation and cannot meet diverse user needs. Therefore, multi-segment tracks have begun to be used in the market. Multi-segment tracks facilitate transportation and meet diverse user requirements. However, the existing splicing structure of splicing tracks is overly complex, resulting in high splicing costs and inconvenience for replacement and maintenance, increasing maintenance costs and time. Summary of the Invention

[0003] The purpose of this invention is to address the above-mentioned problems by providing a curtain splicing track.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A curtain splicing track includes at least two coaxially distributed track bodies. A connector is sleeved between two adjacent track bodies, and both ends of the connector extend to the outside of different track bodies. At least one side of the connector is provided with a track connecting structure. The track connecting structure has at least two track connecting components, and at least one track connecting component corresponds to the outside of any one of the two adjacent track bodies. The track connecting component is a screw-on track connecting component and / or a snap-on track connecting component that can abut against the outside of the track body to axially position the two adjacent track bodies. The connector and track connecting structure facilitate the splicing and connection of different track bodies and can meet the splicing of track bodies of various lengths, satisfying customer needs. Furthermore, the screw-on track connecting component facilitates splicing and locking operations for users and reduces splicing costs.

[0005] In the aforementioned curtain track, the lower side of the track body has a track groove, and the connector side has a connector opening corresponding to the track groove. The connector is an integral structure that matches the shape of the track body and is sleeved on the outside of the track body. The upper side of the connector has a connector fixing plate with several fixing holes. The lower side of the connector has lower hooks located on both sides of the connector opening. The lower hooks engage with two lower slots located on the side of the track body with the track groove, respectively on both sides of the track groove. The lower hooks face away from the connector. The connector has an inclined opening and a top locking part on its upper side that engages with a recessed part on the side of the track body away from the track groove. Alternatively, the connector has upper hooks on both the front and rear sides, and the upper hooks engage with upper grooves located on the side of the track body. The upper hooks are inclined toward the lower hooks. When the upper hooks on the front and rear sides of the connector are used, the bidirectional inclined design of the upper hooks toward the lower hooks creates a self-locking effect, further strengthening the engagement strength between the connector and the track body and improving the connection stability between the connector and the track body.

[0006] In one type of curtain track described above, track connection structures are provided on the front and rear sides of the connector; or, track connection structures are provided on the front and rear sides of the connector and on the side of the connector away from the connector opening; the track connection structure has two track connection components, each corresponding to the outer side of two adjacent track bodies; or, the track connection structure has three track connection components, wherein two track connection components correspond to the outer side of two adjacent track bodies and the remaining track connection component is located between two adjacent track bodies. The three track connection components can ensure the connection stability between the connector and the track body, effectively avoid connector offset or deformation caused by uneven force on one side, and improve the overall rigidity of the system.

[0007] In the aforementioned curtain track, the front and rear sides of the connector and / or the side of the connector away from the connector opening are respectively provided with track connecting blocks located between the outer sides of two adjacent track bodies. Each track connecting block has several rubber strips on one side that contact the outer side of the track body. Both ends of the track connecting block extend to different sides of the track body. An installation gap is formed between the inner side of the connector and the outer side of the track body. The track connecting block is positioned within the installation gap, and both sides of the track connecting block abut against the inner side of the connector and the outer side of the track body, respectively. The track connecting block has at least two knob mounting holes, and two of these knob mounting holes correspond to different sides of the track body. When there are three knob mounting holes, and the other knob mounting hole corresponds to the connection point of an adjacent track body, the installation gap facilitates the installation of the track connecting block. The knob mounting holes have a snap-on track connecting component, which abuts against the side of the track body through the knob mounting hole, ensuring the effective connection between the track connecting blocks and the track bodies.

[0008] In the aforementioned curtain track, the snap-lock track connector includes a pressing knob rotatably mounted in a knob mounting hole. The inner end of the pressing knob corresponds to the outer side of the track body, and the outer end of the pressing knob abuts against the inner side of the connector. A knob pressing control component is provided between the knob mounting hole and the pressing knob, allowing the pressing knob to move towards the outer side of the track body when rotated circumferentially, thus causing the inner end of the pressing knob to abut against the outer side of the track body. The knob mounting hole is a stepped hole with an inner hole and an outer hole, the outer hole diameter being larger than the inner hole diameter. An annular step is formed between the hole and the inner hole. The pressing knob has a knob disc-shaped part that is rotatably disposed in the outer hole, and the outer side of the knob disc-shaped part is flush with the outer side of the outer hole. The center of the knob disc-shaped part is provided with a top pressure column-shaped part that is rotatably disposed in the inner hole and extends out of the inner hole. The knob pressing control component is disposed between the annular step and the knob disc-shaped part. The knob disc-shaped part is abutted against the annular step, and the top pressure column-shaped part can press against the outer side of the track body through the inner hole during the rotation of the pressing knob, so as to ensure the pressing effect of the pressing knob on the track body and ensure the connection effect.

[0009] In the aforementioned curtain track, the knob pressing control assembly includes at least one arc-shaped pressing slope disposed on an annular step. The height of the arc-shaped pressing slope gradually increases from one end to the other. One end of the knob disc-shaped portion is provided with at least one arc-shaped mating slope that matches the arc-shaped pressing slope. The height of the mating slope gradually increases from the end corresponding to the higher end of the arc-shaped pressing slope to the other end. The annular step has two arc-shaped pressing slopes connected end to end to form an annular structure. A first limiting step is formed between the higher end of one of the arc-shaped top-pressing inclined surfaces and the lower end of the other arc-shaped top-pressing inclined surface. One end of the knob disc-shaped portion has two arc-shaped mating inclined surfaces, which are connected end-to-end to form a ring structure coaxial with the top-pressing column-shaped portion. A second limiting step is formed between the higher end of one of the arc-shaped mating inclined surfaces and the lower end of the other arc-shaped mating inclined surface. The first limiting step has a vertically positioned lower limiting block, and the pressing knob has a horizontally extending upper limiting block located on one side of the second limiting step. The block has a limiting groove on one side of the higher end of the arc-shaped top-pressing inclined surface, and a limiting protrusion on one side of the second limiting step on the higher end of the arc-shaped mating inclined surface. The connector has locking operation holes corresponding to the pressing knobs, each smaller than the knob disc-shaped portion, with the knob disc-shaped portion abutting against the inner side of the locking operation hole. The outer end of the knob disc-shaped portion has a locking groove corresponding to the locking operation hole and a locking mark. The first and second limiting steps respectively abut against the arc-shaped top-pressing inclined surface and the arc-shaped mating inclined surface. Furthermore, when the knob disc rotates, the second limiting step moves towards the higher position of the first limiting step via the arc-shaped top pressing slope and the arc-shaped matching slope. The connector can limit the knob disc, causing the top pressing column of the knob disc to move towards the inner hole. When the upper limit block and the lower limit block abut against each other, the top pressing column presses against the track body, ensuring the connection effect. When the knob disc rotates and presses, the limiting protrusion engages with the limiting groove, ensuring the pressing stability of the knob disc. The locking operation hole allows the user to easily control the knob disc, improving operating efficiency.

[0010] In the aforementioned curtain track, the connector is a split structure consisting of two symmetrically distributed connector halves. The connector halves are radially positioned on the front and rear sides of the track body, with the connector opening formed between the lower sides of the two halves. The track connector block has at least two compression block mounting holes. Each compression block has a compression block inside the mounting hole, with both ends extending to the sides of the mounting hole. Knob mounting holes are located within the compression blocks, with both sides of the compression blocks flush with the sides of the track connector block. Compression block limiting grooves are provided on both sides of the mounting holes, and compression block limiting portions extend into these grooves on both sides of the compression blocks. These limiting portions are inserted into the limiting grooves, ensuring the stability of the compression blocks within the mounting holes. The mounting holes facilitate the installation of the compression blocks, and the compression knobs are all located within the knob mounting holes of the compression blocks, improving the installation efficiency of the compression knobs.

[0011] In the aforementioned curtain splicing track, the snap-on track connection assembly includes two snap-on components disposed on at least one side of the connector, with the two snap-on components on the same side of the connector symmetrically arranged along the boundary line of adjacent track bodies. A snap-on installation channel is provided between the inner sides of the connector and the outer sides of the track bodies, and the snap-on components are respectively disposed within the snap-on installation channel. Each snap-on component includes a snap-on housing located between the inner side of the connector and the outer side of the track body. The snap-on housing is movably provided with snap-on bodies corresponding to different track bodies. Each snap-on body has a locking post rotatably disposed inside the snap-on housing with a cam-shaped cross-section. The outer side of the locking post protrudes from the inner side of the snap-on housing and abuts against the outer side of the track body. The locking post is connected to a locking wrench extending outwards from the outer side of the connector. The snap-on housing facilitates the installation of the snap-on body, and the locking wrench allows for easy control of the locking post's rotation, ensuring a tight fit between the locking post and the track body and guaranteeing the connection effect of the connector.

[0012] In the aforementioned curtain track, the buckle housing has a locking post mounting groove on one side near the track body. The locking post is rotatably mounted in the locking post mounting groove via a hinge shaft. The other side of the buckle housing has a movable groove communicating with the locking post mounting groove. The locking wrench is circumferentially connected to the locking post and movably mounted in the movable groove. The connector has a wrench groove corresponding to the movable groove. The locking wrench extends out of the wrench groove through the movable groove. The size of the wrench groove is larger than the size of the movable groove, which facilitates the rotation of the locking wrench within the wrench groove.

[0013] In the aforementioned curtain splicing track, the buckle housings are respectively inserted and positioned inside the end of the buckle mounting channel. One end of the buckle housing has a housing end plate that can close the end of the buckle mounting channel and matches the shape of the buckle mounting channel. The locking wrench is bent and the locking wrench and locking post are integrated into one structure. The bent locking wrench facilitates user control, and the integrated structure can improve the overall structural strength and service life.

[0014] Compared with existing technologies, the advantages of this invention are:

[0015] 1. The connector can be fixedly fitted onto the outer circumference of the track body through the track connection structure and track connection block to complete the connection operation. The structure is simple and can ensure connection stability.

[0016] 2. The rail connection components include both screw-on and snap-on types, and users can choose different connection control methods according to their needs, thus improving the user experience.

[0017] 3. The squeeze knob and buckle assembly can improve the connection effect of the track body and make it easier for users to operate, thus improving the connection efficiency of the track body.

[0018] 4. The knob compression control component ensures the compression stability of the compression knob on the track body and guarantees the connection stability of the track body. Attached Figure Description

[0033] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0034] Example 1

[0035] like Figure 1 , Figure 2 , Figure 3 , Figure 6 , Figure 7As shown, this type of curtain splicing track includes at least two coaxially distributed track bodies 1. A connector 2 is sleeved between two adjacent track bodies 1, and both ends of the connector 2 extend to the outside of different track bodies 1. At least one side of the connector 2 is provided with a track connecting structure 3. The track connecting structure 3 has at least two track connecting components 31, and the outside of any one of the two adjacent track bodies 1 corresponds to at least one track connecting component 31. The track connecting component 31 is a snap-lock type track connecting component 32 that can abut against the outside of the track body 1 to axially position the two adjacent track bodies 1. Through the connector 2 and the track connecting structure 3, it is easy to splice and connect different track bodies 1 and meet the splicing of track bodies 1 of various lengths, thus meeting customer needs. Furthermore, the snap-lock type track connecting component 32 facilitates splicing and locking operations for users, reduces splicing costs, and achieves a minimum splicing accuracy of 5 cm, further improving the applicability of the splicing track.

[0036] Specifically, the lower side of the track body 1 is provided with a track groove 11, and one side of the connector 2 has a connector opening 21 corresponding to the track groove 11, which enables the connector 2 to be quickly positioned and slidably fitted, improving installation efficiency. The connector 2 has an integrated structure that matches the shape of the track body 1 and is sleeved on the outside of the track body 1, matching the shape of the track body 1, reducing assembly errors and improving the overall structural integrity. The upper side of the connector 2 is provided with a connector fixing plate 22 with several fixing holes 221, which can be fixed by... Hole 221 facilitates the installation and fixation of the connector fixing plate 22, ensuring the installation stability of the connector 2. The lower side of the connector 2 has lower hook portions 23 located on both sides of the connector opening 21. The lower hook portions 23 engage with two lower slots 12 located on both sides of the track groove 11 on one side of the track body 1. The lower hook portions 23 are inclined away from the connector opening 21. The upper side of the connector 2 has a recess 13 on the side of the track body 1 away from the track groove 11. The top locking part 24, which is connected by a snap-fit ​​mechanism, can automatically guide and lock with the lower locking groove 12 during installation via a tilted lower hook part 23, improving installation efficiency. The lower hook part 23 engages symmetrically on both sides, evenly distributing lateral stress and effectively preventing misalignment or detachment between the track body 1 and the connector 2. The top locking part 24 also has a track connection structure 3, which connects and locks the recessed part 13, effectively preventing the connector 2 from wobbling in the vertical direction and ensuring the stability of the track body 1. Axial stability, or, the connector 2 has upper hooks 25 on the front and rear sides respectively, and the upper hooks 25 are engaged with the upper slots 14 located on the side of the track body 1, and the upper hooks 25 are inclined toward the lower hooks 23. When the upper hooks 25 on the front and rear sides of the connector 2 are used, the bidirectional inclined design of the upper hooks 25 toward the lower hooks 23 forms a self-locking effect, which further strengthens the engagement strength between the connector 2 and the track body 1 and improves the connection stability between the connector 2 and the track body 1.

[0037] The connector 2 has track connection structures 3 on its front and rear sides. These track connection structures 3 on both sides ensure the connection between the connector 2 and the track body 1. Alternatively, the connector 2 has track connection structures 3 on its front and rear sides and on the side furthest from the connector opening 21. These three track connection structures 3 further improve the connection between the connector 2 and the track body 1, ensuring the installation stability between the connector 2 and the track body 1. Each track connection structure 3 has two track connection components 31, which are respectively connected to two adjacent track bodies 1. The outer sides correspond one-to-one, and the connection effect between the connector 2 and the track body 1 can be guaranteed by two track connection components 31; or, the track connection structure 3 has three track connection components 31, of which two track connection components 31 correspond one-to-one with the outer sides of two adjacent track bodies 1 respectively, and the remaining track connection component 31 is set between two adjacent track bodies 1. The connection stability between the connector 2 and the track body 1 can be guaranteed by the three track connection components 31, which can effectively avoid the connector 2 from shifting or deforming due to uneven force on one side, and improve the overall rigidity of the system.

[0038] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 7 As shown, the connector 2 has rail connecting blocks 4 located between the outer sides of two adjacent rail bodies 1 on its front and rear sides and / or on the side of the connector 2 away from the connector opening 21. Each rail connecting block 4 has several rubber strips 41 on one side that contact the outer side of the rail body 1. These rubber strips 41 increase the friction between the rail connecting block 4 and the two adjacent rail bodies 1, ensuring a good fit between the rail connecting block 4 and the rail body 1. The two ends of the rail connecting block 4 extend to different sides of the rail body 1, increasing the contact area with the rail body 1 and ensuring a good connection. An installation gap 5 is formed between the inner side of the connector 2 and the outer side of the rail body 1. The rail connecting blocks 4 are positioned within the installation... Within the gap 5, the track connector 4 is respectively abutted against the inner side of the connector 2 and the outer side of the track body 1 on both sides. The track connector 4 is provided with at least two knob mounting holes 42, and the knob mounting holes 42 on both sides of the knob mounting holes 42 correspond to different sides of the track body 1. When there are three knob mounting holes 42, the other knob mounting hole 42 corresponds to the connection point of the adjacent track body 1. The track connector 5 can be easily installed through the installation gap 5. The knob mounting hole 42 is provided with a snap-lock track connector component 32, and the snap-lock track connector component 32 can abut against the side of the track body 1 through the knob mounting hole 42 to ensure the connection effect between the track connector 4 and the track body 1.

[0039] Furthermore, the rotary track coupling assembly 32 includes a pressing knob 321 rotatably disposed within a knob mounting hole 42. The inner end of the pressing knob 321 corresponds to the outer side of the track body 1, and the outer end of the pressing knob 321 abuts against the inner side of the connector 2. The connector 2 can limit the pressing knob 321, ensuring that the pressing knob 321 can only move towards the track body 1 during rotation, thus guaranteeing the pressing effect of the pressing knob 321. A knob pressing control assembly 6 is provided between the knob mounting hole 42 and the pressing knob 321, which allows the pressing knob 321 to move towards the outer side of the track body 1 when the pressing knob 321 rotates circumferentially, thereby causing the inner end of the pressing knob 321 to abut against the outer side of the track body 1. The knob pressing control assembly 6 facilitates the rotation of the pressing knob 321 towards the track body 1 within the knob mounting hole 42, ensuring the pressing effect of the pressing knob 321 on the track body 1 and improving the coupling effect. The knob mounting hole 42 has an inner hole 421 and... The outer hole 422 is stepped, with a diameter larger than that of the inner hole 421, and an annular step 43 is formed between the outer hole 422 and the inner hole 421. The squeeze knob 321 has a knob disc-shaped portion 3211 rotatably disposed within the outer hole 422, and the outer side of the knob disc-shaped portion 3211 is flush with the outer side of the outer hole 422, which improves the overall aesthetics and facilitates the installation of the knob disc-shaped portion 3211, improving installation efficiency. The knob disc-shaped portion 3211 has a rotating center. A pressure column 3212 is installed in and out of the inner hole 421. A knob compression control assembly 6 is installed between the annular step 43 and the knob disc 3211. The knob disc 3211 is abutted against the annular step 43. During the rotation of the compression knob 321, the pressure column 3212 can press against the outside of the track body 1 through the inner hole 421 to ensure the compression effect of the compression knob 321 on the track body 1 and ensure the connection effect.

[0040] The knob pressing control assembly 6 includes at least one arc-shaped pressing ramp 61 disposed on the annular step 43. The height of the arc-shaped pressing ramp 61 gradually increases from one end to the other. One end of the knob disc 3211 is provided with at least one arc-shaped mating ramp 62 that matches the arc-shaped pressing ramp 61. The height of the arc-shaped mating ramp 62 gradually increases from one end to the other, corresponding to the higher end of the arc-shaped pressing ramp 61. The arc-shaped pressing ramp 61 and the arc-shaped mating ramp 62 enable the knob disc 3211 to rotate stably on the annular step 43, ensuring the rotational stability of the pressing knob 321. The annular step 43 has two arc-shaped pressing ramps 61 connected end to end. The enclosure forms a ring structure. A first limiting step 63 is formed between the higher end of one of the two arc-shaped pressing slopes 61 and the lower end of the other arc-shaped pressing slope 61. One end of the knob disc-shaped portion 3211 has two arc-shaped mating slopes 62 connected end-to-end, forming a ring structure coaxial with the pressing column-shaped portion 3212. A second limiting step 64 is formed between the higher end of one of the two arc-shaped mating slopes 62 and the lower end of the other arc-shaped mating slope 62. The first limiting step 63 has a vertically positioned lower limiting block, and the pressing knob 321 has a horizontally extending section located on one side of the second limiting step 64. The upper limit block has a limiting groove 65 located on one side of the first limiting step 63 at the higher end of the arc-shaped pressing slope 61, and a limiting protrusion 66 on one side of the second limiting step 64 at the higher end of the arc-shaped mating slope 62; the connector 2 is provided with locking operation holes 26 corresponding to the pressing knobs 321 respectively. The locking operation holes 26 are smaller than the knob disc-shaped part 3211 and the knob disc-shaped part 3211 is abutted against the inner side of the locking operation hole 26; the outer end of the knob disc-shaped part 3211 is provided with a locking groove and a locking mark corresponding to the locking operation hole 26. The first limiting step 63 and the second limiting step 64 can respectively abut against the arc-shaped pressing slope 61 and the arc-shaped mating slope 62, and when the knob disc-shaped part 3211 is abutted against the first limiting step 63, the arc-shaped pressing slope 61 and the arc-shaped mating slope 62 are abutted against the first limiting step 63 and the second limiting step 64 ... When 211 rotates, the second limiting step 64 is displaced towards the height of the first limiting step 63 by the arc-shaped top pressing inclined surface 61 and the arc-shaped cooperating inclined surface 62. The connector 2 can limit the knob disc part 3211, causing the top pressing column part 3212 of the knob disc part 3211 to move towards the inner hole 421. When the upper limit block and the lower limit block abut against each other, the top pressing column part 3212 is pressed against the track body 1 to ensure the connection effect. When the knob disc part 3211 is rotated and pressed, the limiting protrusion 66 is engaged with the limiting groove 65 to ensure the pressing stability of the knob disc part 3211. The locking operation hole 26 allows the user to easily control the knob disc part 3211, improving the operating efficiency.

[0041] The principle of this embodiment is that the track connecting block 4 is set on both sides of the track body 1 and on the side away from the track groove 11 through the connector 2, which can ensure the contact area between the track connecting block 4 and the connector 2. The track connecting block 4 can press against the three sides of the track body 1 through the snap-lock track connecting component 32 and the knob squeezing control component 6, which can ensure the connection effect of the track connecting block 4 and the connection effect between the connector 2 and the track body 1.

[0042] Example 2

[0043] This embodiment is basically the same as embodiment one in structure and working principle, except that, as follows: Figure 8 , Figure 9 , Figure 10 As shown, the connector 2 has a split structure consisting of two symmetrically distributed connector halves 27. The connector halves 27 are radially positioned on the front and rear sides of the track body 1, and the connector opening 21 is formed between the lower sides of the two connector halves 27. The track connector block 4 is provided with at least two compression block mounting holes 44. Compression blocks 45 are respectively provided in the compression block mounting holes 44, and the two ends of the compression blocks 45 extend to both sides of the compression block mounting holes 44. Knob mounting holes 42 are respectively provided in the compression blocks 45, and the two sides of the compression blocks 45 are respectively connected to the track. The two sides of the connecting block 4 are flush. The extrusion block mounting hole 44 is provided with extrusion block limiting grooves on both sides. The extrusion block 45 is provided with extrusion block limiting parts extending into the extrusion block limiting grooves on both sides. The extrusion block limiting parts are connected to the extrusion block limiting grooves and can ensure the installation stability of the extrusion block 45 in the extrusion block mounting hole 44. The extrusion block 45 can be easily installed and placed through the extrusion block mounting hole 44. The extrusion knobs 321 are all set in the knob mounting holes 42 in the extrusion block 45, which improves the installation efficiency of the extrusion knobs 321.

[0044] Example 3

[0045] This embodiment is basically the same as embodiment one in structure and working principle, except that, as follows: Figure 11 , Figure 12 , Figure 13As shown, the track coupling assembly 31 is a snap-fit ​​track coupling assembly 33 that can abut against the outer side of the track body 1 to axially position two adjacent track bodies 1. The snap-fit ​​track coupling assembly 33 includes two snap-fit ​​components 331 disposed on at least one side of the connector 2. The two snap-fit ​​components 331 located on the same side of the connector 2 are symmetrically arranged with respect to the boundary line of two adjacent track bodies 1. The symmetrical arrangement of the snap-fit ​​components 331 can further improve the locking effect of the snap-fit ​​components 331 on the track body 1. There is a snap-fit ​​installation channel 7 between the inner sides of the connector 2 and the outer sides of the track body 1, and the snap-fit ​​components 331 are respectively disposed in the snap-fit ​​installation channel 7.
