[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0028] like Figure 1 , Figure 2 The diagram shows a modular guide rail provided in an embodiment of this utility model. This modular guide rail can be used for sliding doors or windows and can cooperate with pulleys on the top of the door or window sash to achieve movement of the door or window sash. The modular guide rail of this embodiment includes a first profile 10, a second profile 20, and a connecting block 30, all of which are independent of each other. The first profile 10, the second profile 20, and the connecting block 30 can all be made of rigid materials such as aluminum alloy, stainless steel, or engineering plastics. Furthermore, the cross-sections of each of the first profile 10, the second profile 20, and the connecting block 30 are the same or substantially the same at various positions along the axial direction.
[0029] like Figure 3 As shown, the first profile 10 has a first guide groove 11 and a first snap-fit groove. The first guide groove 11 and the first snap-fit groove are respectively arranged along the axial direction of the first profile 10. The first guide groove 11 is used to assemble a pulley, that is, a pulley fixed on a door leaf or window leaf can be assembled into the first guide groove 11 and can slide along the axial direction of the first guide groove 11. The first snap-fit groove is located on the first side of the first guide groove 11 (e.g., Figure 3 (The right side of the middle). The structure of the first guide groove 11 is similar to that of the guide groove in the existing guide rail, and will not be described in detail here.
[0030] like Figure 4 As shown, the second profile 20 has a second guide groove 21 and a second snap-fit groove. The second guide groove 21 and the second snap-fit groove are respectively arranged along the axial direction of the second profile 20. The second guide groove 21 is used to assemble pulleys; that is, pulleys fixed to door or window panels can be assembled into the second guide groove 21 and can slide along the axial direction of the second guide groove 21. The second snap-fit groove is located on the second side of the second guide groove 21 (e.g., ...). Figure 4 (Left side of the middle). The structure of the second guide groove 21 is similar to that of the guide groove in the existing guide rail, and will not be described in detail here.
[0031] The connecting block 30 includes adjacent first and second insertion portions. The connecting block 30 inserts its first insertion portion into a first locking groove on the first side of the first profile 10 and its second insertion portion into a second locking groove on the second side of the second profile 20, thereby locking and fixing the side-by-side first profile 10 and second profile 20 together. The first profile 10, second profile 20, and connecting block 30, which are fixed together, can be assembled as a whole into a door frame or window frame.
[0032] The aforementioned modular guide rails are secured by providing a first snap-fit groove and a second snap-fit groove on the sides of the first profile 10 and the second profile 20, respectively, and by inserting the first insertion part and the second insertion part of the connecting block 30 into the first snap-fit groove and the second snap-fit groove, respectively, thereby locking and fixing the first profile 10 and the second profile 20. Thus, only three profiles are needed to assemble guide rails with different numbers of guide grooves.
[0033] In one embodiment of this utility model, the axial dimension of the first profile 10 is greater than twice the axial dimension of the connecting block 30, and the axial dimension of the second profile 20 is greater than twice the axial dimension of the connecting block 30. Furthermore, multiple connecting blocks 30 are provided between the first side of the first profile 10 and the second side of the second profile 20. That is, a first profile 10 and a second profile 20 are fixed together by two or more connecting blocks 30. For example, when the axial lengths of the first profile 10 and the second profile 20 are relatively small, the number of connecting blocks 30 can be relatively small; when the axial lengths of the first profile 10 and the second profile 20 are relatively large, the number of connecting blocks 30 can be relatively large. Of course, in practical applications, the axial length of the connecting block 30 can also be the same as the axial lengths of the first profile 10 and the second profile 20, but this increases the weight and material cost of the modular guide rail.
[0034] In one embodiment of the present invention, the first guide groove 11 of the first profile 10 and the second guide groove 21 of the second profile 20 have the same shape and size, thereby enabling the assembly of identical pulleys.
[0035] In one embodiment of this utility model, such as Figure 3 As shown, the first profile 10 includes a first top plate 12, a first side plate 13, and a second side plate 14. The tops of the first side plate 13 and the second side plate 14 are respectively vertically connected to the lower surface of the first top plate 12, and a first guide groove 11 is formed between the first side plate 13 and the second side plate 14 (below the first top plate 12). Furthermore, similar to existing guide rails, a first support portion 18 is provided on the inner side of the bottom of the first side plate 13 and the second side plate 14, thereby supporting the pulley through the first support portion 18.
[0036] Similarly, such as Figure 4As shown, the second profile 20 includes a second top plate 22, a third side plate 23, and a fourth side plate 24. The tops of the third side plate 23 and the fourth side plate 24 are vertically connected to the lower surface of the second top plate 22, and a second guide groove 21 is formed between the third side plate 23 and the fourth side plate 24 (below the second top plate 22). Furthermore, similar to existing guide rails, the inner sides of the bottom of the third side plate 23 and the fourth side plate 24 each have a second support portion 29, which can support the pulley.
[0037] like Figure 2 As shown, in one embodiment of this utility model, the first side of the first top plate 12 (e.g.) Figure 3 The right side of the first side plate 13 protrudes horizontally from the first side plate 13 and protrudes downward at the edge (i.e., the edge of the protruding part) to form a first hook 15 (a slot is formed between the first hook 15 and the outer side of the first side plate 13). The bottom outer side of the first side plate 13 extends horizontally outward and protrudes upward at the edge (i.e., the edge of the extended part) to form a second hook 16 (a slot is formed between the second hook 16 and the outer side of the first side plate 13). A first snap-fit groove is formed between the first hook 15, the second hook 16 and the outer side of the first side plate 13, that is, the first snap-fit groove is C-shaped.
[0038] like Figure 4 Accordingly, the second side of the second top plate 22 (e.g.) Figure 4 The third side plate 23 protrudes horizontally from the left side of the third side plate 23. The bottom outer side of the third side plate 23 extends horizontally outward and protrudes upward at the edge to form a third hook 25 (a slot is formed between the third hook 25 and the outer side surface of the third side plate 23). A second snap-fit groove is formed between the third hook 25, the portion of the second top plate 22 protruding from the outer side surface of the third side plate 23, and the outer side surface of the third side plate 23.
[0039] like Figure 5 As shown, the top two edges of the connecting block 30 bulge upwards to form a first locking strip 31 and a second locking strip 32, respectively, while the bottom two edges of the connecting block 30 bulge downwards to form a third locking strip 33 and a fourth locking strip 34, respectively. The first locking strip 31, the third locking strip 33, and the fourth locking strip 34 are all strips distributed along the axial direction of the connecting block 30. Figure 6As shown, when the connecting block 30 is assembled between the first profile 10 and the second profile 20, the first top plate 12 and the second top plate 22 abut against each other, the first locking strip 31 is inserted between the first hook portion 15 and the first side plate 13, the third locking strip 33 is inserted between the second hook portion 16 and the first side plate 13, the second locking strip 32 abuts against the lower surface of the second top plate 22 and the outer side surface of the third side plate 23, and the fourth locking strip 34 is engaged between the third hook portion 25 and the outer side surface of the third side plate 23. Those skilled in the art will understand that, to improve the stability of the connection, the widths of the first locking strip 31, the third locking strip 33, and the fourth locking strip 34 (e.g., ...) are... Figure 4 The dimensions (in the direction indicated by the middle arrow X) are respectively adapted to the distances between the first hook 15 and the first side plate 13, the second hook 16 and the first side plate 13, and the third hook 25 and the third side plate 23. Through the above structure, the first profile 10 and the second profile 20 can be locked and fixed.
[0040] To further improve the stability of the connection between the first profile 10 and the second profile 20, in one embodiment of this utility model, a fourth hook 26 protrudes downward from the edge of the second side of the second top plate 22. The distance between the fourth hook 26 and the third side plate 23 is greater than the distance between the first hook 15 and the first side plate 13. Simultaneously, the outer side of the bottom of the third side plate 23 has a fifth hook 27 opposite to the fourth hook 26. Correspondingly, the top of the connecting block 30 also has a fifth locking strip 35 that protrudes vertically upward, and the distance between the fifth locking strip 35 and the first locking strip 31 is adapted to the sum of the widths of the first hook 15 and the fourth hook 26. The bottom of the connecting block 30 also has a sixth locking strip 36 that protrudes vertically downward, and the distance between the sixth locking strip 36 and the third locking strip 33 is adapted to the sum of the widths of the second hook 16 and the fifth hook 27. When the connecting block 30 is assembled between the first profile 10 and the second profile 20, the first hook 15 and the fourth hook 26 engage between the first locking strip 31 and the fifth locking strip 35, and the second hook 16 and the fifth hook 27 engage between the third locking strip 33 and the sixth locking strip 36. Figure 6 As shown.
[0041] Furthermore, a connecting plate 28 is provided below the third hook portion 25 and the fifth hook portion 27, and when the connecting block 30 is assembled between the first profile 10 and the second profile 20, the bottoms of the first profile 10 and the second profile 20 abut against each other through the connecting plate 28. This structure improves the surface consistency of the modular guide rail.
[0042] In one embodiment of the present invention, the first side (i.e. the outer side of the fourth side plate) of the second guide groove 21 on the second profile 20 has a third snap-fit groove, which is arranged along the axial direction of the second profile 20 and has the same structure as the first snap-fit groove.
[0043] like Figure 7 As shown, a connecting block 30 can be used to lock and fix another second profile 20 to the first side of the aforementioned second profile 20, thereby giving the modular guide rail three guide slots. That is, the modular guide rail includes two second profiles 20, the second side of one second profile 20 is locked and fixed to the first side of the first profile 10 by connecting blocks 30 that are respectively embedded in the first and second locking slots, and the second side of the other second profile 20 is locked and fixed to the first side of the adjacent second profile 20 by connecting blocks 30 that are respectively embedded in the third and second locking slots.
[0044] With the above structure, more second profiles 20 can be assembled into the guide rail using the connecting block 30, so that the modular guide rail has four guide slots, five guide slots, or even more guide slots.
[0045] In one embodiment of this utility model, the two side walls of the connecting block 30 are each provided with multiple axial protrusions 37. When the connecting block 30 is assembled between the first profile 10 and the second profile 20 (or between the two second profiles 20), the protrusions 37 can abut against the side walls of the first profile 10 and the second profile 20 to prevent loosening between the connecting block 30 and the profile.
[0046] Furthermore, the lower surface of the first top plate 12 has a fixing hole 121 for fixing the first profile 10 to the window frame; similarly, the lower surface of the second top plate 22 has a fixing hole 221 for fixing the second profile 20 to the window frame.
[0047] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
