[0002] In the technical field of doors and windows, drive rods are a common component configured to operate the opening and closing of doors and windows. For ease of use, products with quieter operation are generally selected. However, conventional drive rods are prone to generating noise due to metal-on-metal friction during the opening and closing process, which not only affects the ease of use of the doors and windows but can also impact the surrounding environment. To address the above issues, a damping mechanism is incorporated into the drive rod. The damping mechanism typically includes a damping spring, a damping pad, etc., which can reduce noise by absorbing vibrations from the drive rod during operation.However, the damping mechanism can only reduce noise to a certain extent, and cannot eliminate noise completely.

[0032] In one embodiment of the present application, as shown in Figures 1 to 8, a silent transmission rod is provided, which is configured to be mounted in a notch 310 of a profile 300 and connected to a locking block of the profile 300. The silent transmission rod includes a transmission rod base 10 and a bearing base 20. The transmission rod base 10 has a mounting groove 11. The bearing base 20 is mounted in the mounting groove 11, and opposite ends of the bearing base 20 extend out of the mounting groove 11. The bearing base 20 may be made of plastic. One side of the bearing base 20 away from the mounting groove 11 has a first projection 21, and the first projection 21 is in contact with a side wall of the notch 310.The opposite ends of the bearing base 20 extend out of the mounting groove 11 and form two second projections 22. Both sides of each second projection 22 are in contact with the side wall of the notch 310. One side of the bearing base 20 away from the first projection 21 has two third projections 23, and the two third projections 23 are located adjacent to the opposite ends of the bearing base 20. The transmission rod base 10 is located between the two third projections 23. The two third projections 23 are in contact with the side wall of the notch 310. The first projection 21, the second projection 22, and the third projection 23 are in contact with the side wall of the notch 310, so that the transmission rod base 10 is suspended in notch 310, and the base of transmission rod 10 is spaced from the side wall of notch 310.

[0033] More specifically, the first projection 21 and the third projection 23 cooperate to allow the transmission rod base 10 to be suspended in an up-down direction and spaced away from the side wall of the notch 310, and the second projection 22 allows a left and a right side of the transmission rod base 10 to be spaced away from the side wall of the notch 310. In this way, instead of the transmission rod base 10 being in contact with the side wall of the notch 310, the bearing base 20 is in contact with the side wall of the notch 310. Since the bearing base 20 is made of plastic, friction between metal and metal becomes friction between plastic and metal, the noise during the use of the transmission rod is effectively reduced, and the problem of noise, which is relatively significant during the opening and closing of the transmission rod, is Resolved.

[0034] In this embodiment, as shown in Figures 2 to 8, the first projection 21 includes two arc arms, each in the shape of an arched bridge. A central portion of each arc arm projects outward from the base of the transmission rod 10. More specifically, an outer surface of the arc arm is a curved, arc-shaped surface 211, and an upper part of the arc arm is in contact with the side wall of the notch 310, so as to reduce friction between the base of the pad 20 and the side wall of the notch 310, thereby reducing noise.

[0035] In this embodiment, as shown in Figures 1 to 5 and Figures 7 to 8, one end of each second projection 22 is provided with a convex curved surface 221, and a middle part of the convex curved surface 221 protrudes from a lateral edge of the transmission rod base 10. More specifically, an upper part of the convex curved surface 221 is in contact with the lateral wall of the notch 310, so as to reduce friction between the bearing base 20 and the lateral wall of the notch 310, thereby reducing noise.

[0036] In this embodiment, as shown in Figures 4, 7, and 8, the distance between the upper parts of two convex curved surfaces 221 of the two second projections 22 is 20.5 mm, and the width of the notch 310 is 20 mm. Specifically, the maximum width of the bearing base 20 is 20.5 mm, and the width of the notch 310 is 20 mm, so that the convex curved surfaces 221 of the two second projections 22 are pressed against the lateral walls of the notch 310, thereby preventing the transmission rod base 10 from contacting the lateral wall of the notch 310, and changing the friction between metal and metal into friction between metal and plastic.

[0037] In this embodiment, as shown in Figures 5, [Fig. 7] and [Fig. 8], the third projection 23 is provided on the second projection 22 and is in contact with the side wall of the notch 310. More precisely, the third projection 23 is provided on the side of each of the two second projections 22 opposite the first projection 21. The third projection 23 is in contact with the side wall of the notch 310, so that one side of the transmission rod base 10 corresponding to the third projection 23 is spaced away from the side wall of the notch 310.

[0038] In this embodiment, as shown in Figures 6, 7, and 8, the distance between an upper portion of the first projection 21 and a lower surface of the third projection 23 is 3 mm, and the height of the notch 310 is 3 mm. Specifically, the thickness of the bearing base 20 is 3 mm, and the height of the notch 310 is 3 mm, so that the bearing base 20 fits tightly with the notch 310, and the transmission rod base 10 is suspended.

[0039] In this embodiment, as shown in [Fig. 3], the transmission rod base 10 includes a connecting element 30 provided in the mounting groove 11. The connecting element 30 is connected to the bearing base 20, so that the bearing base 20 is mounted in the mounting groove 11. More specifically, the element The linkage 30 is configured to fix the bearing base 20 to the transmission rod base 10, in order to prevent the bearing base 20 from being separated from the transmission rod base 10.

[0040] In this embodiment, as shown in [Fig. 3], the connecting element 30 is a connecting shaft, and the bearing base 20 is provided with a shaft hole 24 corresponding to the connecting shaft. The connecting shaft is tightly fitted with the shaft hole 24 to secure the bearing base 20 to the transmission rod base 10. More specifically, two connecting shafts are provided in the mounting groove 11. The two connecting shafts are arranged in parallel and are spaced apart, and the two connecting shafts are perpendicular to the transmission rod base 10. The connecting shaft extends through the corresponding shaft hole 24 in a tight fit to connect the transmission rod base 10 to the bearing base 20.

[0041] In this embodiment, as shown in Figures 1 to 4, two bearing bases 20 and two mounting grooves 11 are provided, and the two bearing bases 20 are spaced within the two mounting grooves 11, respectively. More specifically, two mounting grooves 11 are provided and are spaced on the transmission rod base 10. The two bearing bases 20 are in contact with the side wall of the notch 310, so that plastic-metal friction is obtained, thereby reducing noise.

[0042] In this embodiment, as shown in Figures 1 to 4, a locking point cover 40 and a locking point shaft 50 are connected to the transmission rod base 10. The locking point cover 40 and the locking point shaft 50 are configured to be connected to the locking block of the profile. The locking point cover 40 is connected to one end of the locking point shaft 50. One end of the locking point shaft 50, away from the locking point cover 40, extends through the transmission rod base 10 and is fixed to the transmission rod base 10 by riveting.

[0043] The foregoing descriptions are merely specific embodiments of this application, but are not intended to limit the scope of protection of this application. Any variant or replacement readily found by a person skilled in the art within the technical scope disclosed in this application falls within the scope of protection of this application.
