Description

Technical Field

[0001] This utility model relates to the field of roller shutter door winding wheel technology, and in particular, it relates to a stable winding wheel structure. Background Technology

[0002] Currently, roller shutters are widely used in warehouses, garages, shops, etc. Roller shutters are locked with a roller shutter lock and a floor lock to protect the valuables inside. The opening and closing of the roller shutters are controlled by a motor controller on top.

[0003] Some roller shutters have high safety requirements, especially high-speed roller shutters, which roll up and down very quickly. Therefore, the stability of the winding reel and the roller shutter roller at the winding wheel is even more critical. To prevent deformation or damage to the winding reel due to high torque during high-speed operation, a secure connection structure is designed between the winding reel and the roller shutter roller. For example, Chinese utility model patent CN216971834U discloses a novel roller shutter lifting mechanism, including a first fixed plate, on one side of which are sequentially arranged... The device comprises a second and a third fixed plate. A rotating seat, a reducer, and a drive motor are respectively mounted on the first, second, and third fixed plates. The drive motor is connected to the reducer via a coupling. A connecting shaft is mounted on both the reducer and the rotating seat. A drum is positioned between the two connecting shafts. Sheaves are mounted at both ends of the drum, and mounting shafts are mounted on the sheaves. These mounting shafts cooperate with the connecting shafts. Two fourth fixed plates are symmetrically arranged in front of the drum, and gantry frames are mounted on the two fourth fixed plates. A lubrication and winding assembly is mounted on the gantry frames. This invention achieves convenient loading and unloading of the drum through the design of the mounting shafts and connecting shafts. During the winding of the lifting wire rope, the lifting wire rope is not only orderly wound on the drum but also meets the requirements for cleanliness.

[0004] However, the above-mentioned winding wheel structure design still has the following drawbacks: the connection structure between the winding wheel and the roller shutter is complicated, making it inconvenient to install and maintain. Moreover, the connection strength of the roller shutter is still insufficient, and the relatively heavy roller shutter is still easily damaged when the lifting door is running at high speed.

[0005] Therefore, in order to solve the above problems, it is necessary for us to design a reasonable, efficient and stable winding wheel structure. Utility Model Content

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first," "second," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0029] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the invention or its application or use.

[0030] Techniques, methods, and systems known to those skilled in the art may not be discussed in detail, but where appropriate, they should be considered part of the specification.

[0031] Example 1: As Figures 1 to 5 The diagram shown is merely one embodiment of the present invention. A stable winding wheel structure includes a winding disc 2, a roller blind 3, and a connector 1 for connecting the winding disc 2 and the roller blind 3. The winding disc 2 is an annular disc, and at least a portion of the roller blind 3 is located within the winding disc 2. A groove 21 is provided on the inner side of the winding disc 2, and at least a portion of the connector 1 is located within the groove 21. The connector 1 is provided with a first screw 13 for connecting with the winding disc 2 and a second screw 14 for connecting with the roller blind 3.

[0032] In this invention, the winding reel 2 is a circular ring, and the roller shutter 3 can be a solid cylindrical part or a hollow cylindrical part. Whether the roller shutter 3 is hollow or not, and its thickness (difference between inner and outer diameters) when hollow, depends on the specific roller shutter lifting speed, length, and weight. At least a part of the roller shutter 3 is located inside the winding reel 2. In fact, the winding reel 2 is sleeved on the end of the roller shutter 3. Generally, both ends of the roller shutter 3 are sleeved with the winding reel 2. When the motor rotates, it drives the winding reel 2, thereby driving the roller shutter 3 to rotate, thus raising and lowering the roller shutter on the roller shutter 3. In order to ensure a stable connection between the winding reel 2 and the roller shutter 3, a connecting piece 1 is provided at the connection between the winding reel 2 and the roller shutter 3.

[0033] Compared to the traditional structure where the winding reel 2 and the roller shutter roller 3 are directly connected by a screw, resulting in insufficient connection strength, the special structure of the connector 1 in this application can enhance the connection strength between the winding reel 2 and the roller shutter roller 3, specifically:

[0034] First, the connector 1 is connected to the winding reel 2. The winding reel 2 has a groove 21 on its inner side. At least a part of the connector 1 is located in the groove 21. The width of the groove 21 is the same as the width of the main body of the connector 1, and the depth of the groove 21 is the same as the thickness of the main body of the connector 1, so that the main body of the connector 1 is just inserted into the groove 21. At this time, the surface of the connector 1 just contacts the outer wall of the roller shutter 3 inserted into the winding reel 2. The connector 1 is provided with a first screw 13 for connecting with the winding reel 2. The first screw 13 passes through the connector 1 and the winding reel 2 respectively, connecting the connector 1 and the winding reel 2.

[0035] Secondly, the connection between the connector 1 and the roller blind 3 is as follows: the connection surface between the connector 1 and the roller blind 3 is arc-shaped, and the arc of the connector 1 is the same as that of the roller blind 3. That is, the surface of the connector 1 away from the winding reel 2 is tightly fitted with the outer surface of the roller blind 3. Furthermore, the connector 1 is provided with a second screw 14 for connecting with the roller blind 3. The second screw 14 passes through the connector 1 and the roller blind 3 respectively, connecting the connector 1 and the roller blind 3.

[0036] This is equivalent to the connector 1 being snapped into the winding reel 2 and closely connected to the roller blind 3, thus completing the stable connection between the winding reel 2 and the roller blind 3. When the winding reel 2 rotates, it drives the roller blind 3 to raise and lower the roller blind structure.

[0037] This utility model discloses a stable winding wheel structure that uses a connector to connect the winding reel to the roller shutter roller. The connector is snapped into the groove of the winding reel, and the arc-shaped part of the connector fits the roller shutter roller, making the connection between the winding reel, the connector, and the roller shutter roller more stable and stronger. The structure is simple, easy to install and maintain, and can be used for safe use in high-speed lifting doors without being easily damaged.

[0038] Example 2, still as Figures 1 to 5 As shown, this is only one embodiment of the present utility model. Based on the first embodiment, in the stable connection winding wheel structure of the present utility model, the connecting member 1 includes a connecting main board 11 and an arc-shaped plate 12 disposed at the end of the connecting main board 11. The arc-shaped plate 12 is disposed close to the outside of the roller shutter roller 3.

[0039] The first screw 13 and the second screw 14 are both mounted on the main connecting plate 11. The arc-shaped plate 12 is mounted on both sides of the end of the main connecting plate 11. The arc-shaped plate 12 is actually an arc-shaped extension of the main connecting plate 11 to both sides. The arc-shaped plate 12 is mounted on the outside of the roller blind 3 and effectively increases the area of ​​the arc-shaped contact between the connector 1 and the roller blind 3, making the connection between the connector 1 and the roller blind 3 more stable.

[0040] Of course, the connecting motherboard 11 is provided with a first hole 111 for facilitating the passage of the first screw 13 and a second hole for facilitating the passage of the second screw 14.

[0041] There are two second screws 14, and the two second screws 14 are respectively located on both sides of the winding reel 2; that is, the connecting main board 11 extends out from both ends of the slot 21 of the winding reel 2 and is located on both sides of the winding reel 2. Then, a second hole is opened at the position where the connecting main board 11 extends out of the slot 21 and a second screw 14 is set to complete the connection between the connector 1 and the roller shutter 3.

[0042] The first screw 13 is located between the two second screws 14, and the bottom of the slot 21 is provided with a third hole 22 for the first screw 13 to pass through. After the first screw 13 is inserted into the third hole 22 from the winding reel 2, it is inserted into the first hole 111 of the connecting motherboard 11 located in the slot 21, thus completing the connection between the connector 1 and the winding reel 2.

[0043] Example 3, still as Figures 1 to 5 As shown, this is only one embodiment of the present invention. Based on any of the above embodiments, in the stable connection winding wheel structure of the present invention, a functional component 4 is further provided at the connection between the winding disc 2 and the roller shutter 3. The functional component 4 includes a main block 41 and an extension plate 42 provided at the end of the main block 41. A functional groove 23 is provided on the end face of the winding disc 2 to facilitate the insertion of the main block 41. A third screw 43 is provided on the extension plate 42 for connecting with the roller shutter 3.

[0044] The main block 41 is inserted into the functional groove 23, and the extension plate 42 extends out in a direction away from the functional groove 23. Of course, the side of the extension plate 42 near the roller blind 3 is also arc-shaped, so that the extension plate 42 fits against the outside of the roller blind 3. Then, the extension plate 42 is connected to the roller blind 3 by the third screw 43.

[0045] Of course, the main body block 41 is provided with a first threading hole 44; the bottom of the functional groove 23 is provided with a second threading hole 24 for communicating with the first threading hole 44; after the third screw 43 connects the extension plate 42 to the roller shutter roller 3, the first threading hole 44 is connected to the second threading hole 24, which makes it convenient for the pull rope of the roller shutter door to pass through.

[0046] It should be noted that functional component 4 also plays a role in stabilizing the connection between the winding disc 2 and the roller shutter 3.

[0047] Example 4, still as Figures 1 to 5 As shown, this is only one embodiment of the present invention. Based on any of the above embodiments, in the stable connection winding wheel structure of the present invention, the number of connecting parts 1 is at least two; multiple connecting parts 1 make the connection between the winding disc 2 and the roller shutter 3 more stable.

[0048] In this utility model, the first hole 111 is an elongated hole, so that when the first screw 13 is inserted into the first hole 111, it is only pre-installed and can be adjusted appropriately until the second screw 14 is tightened, and then the first screw 13 is tightened to complete the final stable connection.

[0049] In this utility model, the connector 1, the winding reel 2, and the roller shutter 3 are all integrally formed parts.

[0050] This utility model discloses a stable winding wheel structure that uses a connector to connect the winding reel to the roller shutter roller. The connector is snapped into the groove of the winding reel, and the arc-shaped part of the connector fits the roller shutter roller, making the connection between the winding reel, the connector, and the roller shutter roller more stable and stronger. The structure is simple, easy to install and maintain, and can be used for safe use in high-speed lifting doors without being easily damaged.

[0051] This utility model is not limited to the specific embodiments described above, and various modifications and variations are possible.
