Description

Technical Field

[0001] This utility model relates to the field of corner assembly, and in particular to a corner assembly mechanism. Background Technology

[0002] Corner brackets are crucial components used to connect two perpendicular profiles of a door or window frame. Existing louvers, besides using corner brackets to connect the two perpendicular profiles, can also be used to control the rotation or retraction of the louvers within the window sash. Specifically, a hinge wheel is installed inside the corner bracket, connected to the louver's rotating shaft. A drive rope is wound around the hinge wheel; pulling the drive rope causes the hinge wheel to rotate back and forth, thereby driving the louver's rotating shaft to rotate back and forth, thus achieving the louver's rotation.

[0003] The existing corner assembly is a split structure, using two interlocking side plates and positioning pins for positioning. Bearings are required to support and position the page-turning wheel, ensuring concentricity between the wheel and the shaft, and reducing friction between the wheel and the corner assembly. Clearly, this type of corner assembly has many components, requires distinguishing between left and right parts for installation, involves numerous assembly steps, and results in high costs for automated assembly equipment, while manual assembly is inefficient and leads to high production costs.

[0004] Furthermore, the retractable cords of the louver are connected to both the louver itself and the drive assembly, bypassing the corners of the frame. Users release the cords by moving the drive assembly upwards within the profile, causing the louvers to lower. However, if the user continues to move the drive assembly upwards, the cords may release excessively and droop to one side of the louver, causing them to protrude from the surface and affecting the aesthetics of the blinds.

[0030] To make the objectives, technical solutions, and advantages of this utility model clearer, the following will describe this utility model in further detail with reference to the accompanying drawings. It is hereby declared that the terms "up," "down," "left," "right," "front," "back," "inner," and "outer," etc., appearing or about to appear in this document, are based solely on the accompanying drawings and are not intended to specifically limit this utility model.

[0031] See Figure 1-5 This utility model discloses a corner assembly mechanism, including a corner assembly body 1 and a page-turning component 2 installed in the corner assembly body 1, wherein the corner assembly body 1 is integrally formed.

[0032] The corner assembly body 1 has a mounting opening 1a at the top, a rope passage opening 1c at the bottom, and a jacking interface 1b on the side. The flap-turning component 2 is installed inside the corner assembly body 1 through the mounting opening 1a and extends to the jacking interface 1b. The flap-turning component 2 is located above the rope passage opening 1c. The flap-turning component 2 is installed inside the corner assembly body 1 through the mounting opening 1a and extends to the jacking interface 1b, connecting to the louver's rotating shaft. The drive rope enters the corner assembly body from one end of the rope passage opening, wraps around the flap-turning component, and then extends out from the rope passage opening. The user can pull both ends of the drive rope to drive the flap-turning component to rotate back and forth, thereby driving the louver's rotating shaft to move back and forth, thus driving the louver to flip.

[0033] The corner assembly body 1 includes a housing 11 and a wheel seat 12 installed inside the housing 11. The wheel seat 12 has a wheel groove 121 with an opening facing the mounting port 1a. The page-turning component 2 is mounted on the wheel seat 12 and placed in the wheel groove 121. The page-turning component 2 and the wheel seat 12 are movably connected. The page-turning component is mounted on the wheel seat and can rotate on the wheel seat without the need for additional bearings.

[0034] The corner assembly mechanism of this utility model has a one-piece molded body, eliminating the need for multiple parts for assembly and positioning, and eliminating the need to distinguish between left and right parts. With fewer parts, a simpler structure, fewer assembly steps, and higher assembly efficiency, it also saves costs. Furthermore, the page-turning component is installed in the corner assembly body through a mounting port and mounted on the wheel seat. The page-turning component and the wheel seat are movably connected, eliminating the need for bearings, further reducing the number of parts, making assembly simpler and more efficient, and further saving costs.

[0035] Preferably, the page-turning component 2 is integrally molded, which further reduces the number of parts, simplifies the structure, makes assembly easier and more efficient, and further saves costs.

[0036] Among them, such as Figure 2 , 4 As shown in Figure -5, the page-turning component 2 includes a shaft 21 and a wheel 22. The wheel 22 is sleeved on the shaft 21 and is circumferentially fixed relative to the shaft 21. The wheel seat 12 has a shaft groove 122, which is located on the side wall of the wheel groove 122. Both ends of the shaft 21 are respectively embedded in the shaft groove 122; the wheel 22 is placed within the wheel groove 122. That is, both ends of the shaft are respectively mounted on the wheel seat, the shaft groove and the shaft are compatible, and the shaft groove serves to limit the movement of the shaft. A drive rope is wound around the wheel; pulling the drive rope causes the wheel to rotate, thereby driving the shaft to rotate within the shaft groove.

[0037] Preferably, the shaft 21 is made of metal, and the wheel seat 12 is made of plastic. More preferably, the metal material is stainless steel, and the plastic is POM or nylon, but this is not a limitation. Metal materials such as stainless steel have low friction and low resistance when in contact with plastic, thus having little impact on the rotation of the page-turning mechanism. POM or nylon are wear-resistant and have a low coefficient of friction. Therefore, the page-turning mechanism can rotate smoothly without the need for bearings.

[0038] Among them, such as Figure 4As shown, the inner wall of the housing 11 is provided with a rope guide groove 111, which extends upward from the rope passage opening 1c to the bottom of the wheel seat 12; the bottom of the wheel seat 12 is provided with a rope passage hole 123, and the rope guide groove 111 communicates with the wheel groove 121 through the rope passage hole 123. The rope guide groove is designed to limit the movement of the drive rope placed in the corner, preventing excessive movement of the drive rope and thus avoiding excessive effort when driving the page-turning component, and also preventing the drive rope from detaching from the wheel body and failing to drive the page-turning component to rotate, thereby avoiding drive failure. The drive rope passes through the bottom of the wheel seat through the rope passage hole, can wrap around the wheel body, and then extend out of the corner from the rope passage hole and the rope guide groove on the other side. Therefore, the rope guide groove and the rope passage hole are respectively provided on opposite sides of the housing and the wheel seat, and are correspondingly provided to the wheel body.

[0039] Preferably, such as Figure 1-5 As shown, one end of the shaft 21 is provided with a coupling 23, and the shaft 21 extends to the adapter 1b via the coupling 23. The coupling 23 is provided with a bushing groove. The shaft extends to the adapter via the coupling, and the louvered fan's shaft is inserted into the bushing groove. The wheel drives the shaft to rotate, and the shaft then drives the coupling to rotate, thereby driving the louvered fan's shaft to rotate. The coupling 23 is cylindrical in shape; the shaft 21, wheel 22, and coupling 23 are coaxially arranged. The coupling, in addition to connecting to the louvered fan's shaft, also replaces a bearing, ensuring concentricity.

[0040] Preferably, such as Figure 2 , 4 As shown, the wheel seat 12 is provided with a positioning protrusion 124 for confining the shaft 21 within the shaft groove 122. The positioning protrusion 124 is located above the shaft groove 122. The positioning protrusion plays a role in limiting the shaft, preventing the shaft from easily dislodging from the shaft groove. During installation, force is required to overcome the resistance of the positioning protrusion to press the shaft into the shaft groove.

[0041] To make it easier for the shaft to overcome the positioning protrusion and pass over it, preferably, the outer surface of the positioning protrusion 124 is an arc surface, and the arc surface contacts the shaft and is subjected to force, making it easier for the shaft to pass over the positioning protrusion and enter the shaft groove.

[0042] Furthermore, this utility model also includes a rope locking assembly disposed within the housing 11. The rope locking assembly is used to lock the retractable rope of the louver to prevent the retractable rope from being too long and drooping, thus affecting the aesthetics of the louver.

[0043] like Figure 3-4As shown, the cord locking assembly includes a cord locking magnet 3 and a cord locking component 4, which are magnetically connected. The cord locking magnet 3 is fixedly connected to the housing 11, and the cord locking component 4 is movably connected to the housing 11. Specifically, the retractable cord is placed between the cord locking magnet 3 and the cord locking component 4. When the louver is retracted, the retractable cord tightens, pushing the cord locking component upward to overcome the magnetic attraction and separate the cord locking component from the cord locking magnet. At this time, pulling the retractable cord allows it to move on the surface of the cord locking component. After the louver is fully lowered, the retractable cord relaxes due to the lack of force and no longer exerts an upward pushing force on the cord locking component. At this time, the magnetic attraction between the cord locking magnet and the cord locking component causes the cord locking component to move towards the cord locking magnet, thereby clamping the retractable cord between them. In this way, even if the user continues to move the drive assembly upward, the retractable cord will not be released too much and droop on one side of the louver, preventing the retractable cord from being exposed on the surface of the louver and ensuring the aesthetics of the louver.

[0044] Preferably, such as Figure 4 As shown, the rope locking component 4 includes a rotating shaft 41 and a rotating sleeve 42 sleeved around the rotating shaft 41. The rotating sleeve 42 can rotate around the rotating shaft 41. The rotating shaft 41 is made of a ferromagnetic material, such as iron, cobalt, or nickel. The rotating sleeve can rotate around the rotating shaft, and when the rope moves on the surface of the rope locking component, the rotating sleeve reduces the friction between the rope and the rope locking component.

[0045] Preferably, such as Figure 3-4 As shown, the inner wall of the housing 11 is provided with a guide groove 112, one end of which passes through the rope opening 1c, and the other end is closed. The rope-locking magnet 3 and the rope-locking component 4 are both located within the guide groove 112, and the rope-locking component 4 can move along the guide groove 112; the rope-locking component 4 is installed inside the housing 11 through the guide groove 112. During installation, the rope-locking component is pushed into the guide groove from the rope opening and placed at the closed end of the guide groove. The opposite side walls of the housing are provided with through holes adapted to the rope-locking magnet. The rope-locking magnet is inserted into the housing through the through holes and placed in the guide groove, at which point the rope-locking magnet is positioned below the rope-locking component. Without the action of the rope being wound or unwound, the rope-locking component moves towards the rope-locking magnet under the guidance of the guide groove and magnetically connects with the rope-locking magnet. The guide groove guides the movement of the rope-locking component. Its structure is simple, with few parts, few assembly steps, and high assembly efficiency.

[0046] In addition, such as Figure 3-4 As shown, the rope locking assembly also includes a steering wheel 5. The inner wall of the housing 11 has a mounting groove 113, one end of which passes through the rope opening 1c, and the other end is closed. The steering wheel 5 is fixedly installed inside the housing 11 via the mounting groove 113. The side wall of the housing has a pivot hole, through which the pivot of the steering wheel is inserted into the housing to position the steering wheel within the housing. The steering wheel provides support and direction for the rope winding and unwinding, and also facilitates the application of a pushing force to the rope locking component during rope winding and unwinding.

[0047] In summary, this utility model provides a corner assembly mechanism with fewer parts, fewer assembly steps, and higher assembly efficiency, while ensuring the aesthetics of the louvers.

[0048] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications are also considered to be within the protection scope of this utility model.
