Description

Technical Field

[0001] This utility model belongs to the field of transmission technology, and specifically relates to a U-groove type transmission bar for doors and windows. Background Technology

[0002] Transmission devices and transmission bars are among the most common hardware components in the door and window industry;

[0003] Currently, the transmission strips and transmission boxes in existing technologies are generally integral structures. Different sizes of doors and windows require the installation of different matching transmission strips, which is inconvenient to manufacture and has a relatively high manufacturing cost.

[0004] Furthermore, the drive bars are mostly connected in a sawtooth pattern, which is complex to manufacture, wastes materials, and is not aesthetically pleasing; installation is also not very convenient, as the sawtooth connection is prone to tooth breakage, making it impossible to open or close the window. Utility Model Content

[0005] This utility model provides a U-groove type transmission strip for doors and windows, which can solve the problems pointed out in the background art.

[0006] A U-groove type transmission strip for doors and windows includes a transmission strip body, an upper limit connector, and a guide cover plate. The guide cover plate provides reciprocating sliding limit guidance for the transmission strip body. The upper limit connector is connected in the profile groove to limit the transmission strip body and prevent it from displacing outward. The two ends of the transmission strip body have connecting ends.

[0007] Preferably, the transmission bar is a grooved transmission bar, and the guide cover has a limiting guide protrusion, which is used for sliding and limiting guidance on the inner side of the grooved transmission bar.

[0008] Preferably, the transmission bar is a grooved transmission bar, and the guide cover has a limiting guide protrusion, which is used for sliding and limiting guidance on the inner side of the grooved transmission bar.

[0009] Preferably, the upper limit connector is an upper limit sliding guide groove, which provides an outer limit for the transmission bar, as well as limits on the left and right sides.

[0010] Preferably, the grooved transmission bar has limiting protrusions on both sides, and the limiting sliding guide groove has guide limiting grooves on both sides that cooperate with the limiting protrusions.

[0011] Preferably, the outer sides of the limiting sliding guide groove are respectively provided with limiting slots.

[0012] Preferably, the upper limit connector is connected to the embedded groove, and is stably connected in the profile groove through the embedded groove. The inner sides of the embedded groove provide limits for the left and right sides of the transmission bar.

[0013] Preferably, the upper end of the pre-embedded groove is provided with a locking head on both sides, and the upper limit connector is provided with a corresponding locking groove that cooperates with the locking head.

[0014] Beneficial effects: This utility model provides a U-groove type transmission strip for doors and windows. The transmission strip is designed separately to form a separate structural form, no longer integrated with the transmission box. When in use, it can be adapted to different transmission boxes and transmission devices. The appropriate length can be cut as needed (install all components in the groove, then measure the dimensions between the connection points, cut and punch the transmission strip according to the measured dimensions, and then install it). It has excellent applicability, facilitates turnover, reduces production costs, and facilitates manufacturing.

[0015] Furthermore, the transmission bar has limiters around its perimeter, enabling it to slide smoothly and stably, effectively preventing disengagement.

[0016] It is also suitable for PVC profile doors and windows and wooden windows. Attached Figure Description

[0026] The following describes a specific embodiment of the present invention in detail with reference to the accompanying drawings. However, it should be understood that the scope of protection of the present invention is not limited to the specific embodiment.

[0027] Example 1: As Figure 1-4 As shown in the figure, this utility model provides a U-groove type transmission strip for doors and windows. This embodiment is applicable to PVC profile doors and windows. It includes a transmission strip body 1, an upper limit connector 2, and a guide cover plate 3. The guide cover plate 3 provides reciprocating sliding limit guidance for the transmission strip body 1. The upper limit connector 2 is connected in the profile groove 6 to limit the transmission strip body 1 and prevent it from displacing outward. The two ends of the transmission strip body 1 have connecting ends 4 for connecting with other accessories, such as transmission devices and transmission boxes. The outer end of the guide cover plate 3 is provided with a connecting end 32 for connection. The connecting end 32 can be a connecting clip.

[0028] Specifically, the transmission bar 1 is a grooved transmission bar, and the guide cover plate 3 has a limiting guide protrusion 31, which is used for sliding and limiting guidance on the inner side of the grooved transmission bar.

[0029] Specifically, the transmission bar 1 is a grooved transmission bar, and the guide cover plate 3 has a limiting guide protrusion 31. The limiting guide protrusion 31 is used for inner sliding limiting guidance of the grooved transmission bar. The upper limit connector 2 is an upper limit sliding guide groove, which provides outer limiting for the transmission bar 1, as well as limiting on the left and right sides.

[0030] The grooved transmission bar has limiting protrusions 11 on both sides, and the limiting sliding guide groove has guide limiting grooves 21 on both sides that cooperate with the limiting protrusions 11, so that it can slide more stably.

[0031] Since the profile groove 6 of the PVC profile door and window can produce a limiting block 61, it is preferable that the outer sides of the limiting sliding guide groove are respectively provided with limiting grooves 22, and the limiting grooves 22 cooperate with the limiting block 61 to achieve a stable connection of the upper limit connector 2.

[0032] Example 2: As Figure 5-7 As shown, the difference between this embodiment and embodiment 1 is that it is applicable to wooden doors and windows. Since wooden doors and windows cannot be processed to produce the limiting block 61, the upper limit connector 2 needs to be connected to the pre-embedded groove 5. The pre-embedded groove 5 is stably connected in the profile groove 6. The inner sides of the pre-embedded groove 5 provide limiting for the left and right sides of the transmission bar 1. The upper ends of the pre-embedded groove 5 are respectively provided with the locking head 51, and the upper limit connector 2 is provided with the corresponding locking groove 23 that cooperates with the locking head 51.

[0033] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
