[0015] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0016] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0017] Example like Figures 1 to 9 As shown, a handle assembly suitable for a reclosing mechanism includes a base 6 and a cover plate 7 that matches and covers the base, and a main gear 2. The main gear 2 includes a main gear body 22. One side of the main gear body 22 has an outwardly protruding handle cavity 24, and the other side of the main gear body 22 has an outwardly protruding outer diameter bearing surface cavity 21. The handle cavity 24 and the outer diameter bearing surface cavity 21 are coaxial and located at the central axis of the main gear body 22. The base 6 has a first bearing groove 8, in which a first bearing 3 is embedded. The handle cavity 24 passes through the inner diameter hole of the first bearing 3. The handle cavity 24 is connected to a handle 1 that drives the main gear 2 to rotate. The outer diameter bearing surface cavity 21 is fitted with a second bearing 4. A fixing post 9 is connected to the cover plate 7, and the inner diameter of the second bearing 4 is fitted onto the fixing post 9.

[0018] In this embodiment, the handle 1 is connected to a shaped connecting post 11 for insertion into the handle cavity, wherein the shaped connecting post 11 and the handle are integrally formed. This ensures the handle's sturdiness while allowing for a stable insertion into the handle cavity via the shaped connecting post, facilitating installation and improving stability.

[0019] In this embodiment, a retaining groove 23 for a rotating component is provided on the outer diameter bearing surface cavity 21. The outer diameter bearing surface cavity 21 is connected to a rotating component 5 that rotates synchronously with the main gear through the retaining groove 23. The outer diameter bearing surface cavity 21, the main gear body 22, and the handle cavity 24 are integrally injection molded. This improves the robustness of the main gear.

[0020] In this embodiment, a handle movement limiting area 61 is provided on the back of the base 6 to limit the range of motion of the handle and prevent operator misoperation.

[0021] In this embodiment, the first bearing of this invention has an inner diameter of 6mm and an outer diameter of 10mm, and the second bearing has an inner diameter of 3mm and an outer diameter of 8mm. Alternatively, the bearings can have an inner diameter of 3mm and an outer diameter of 8mm, or an inner diameter of 4mm and an outer diameter of 8mm, or other specifications. Any bearing currently available on the market can be used in this invention.

[0022] like Figure 4 and Figure 5 As shown, the irregularly shaped connecting post 11 of the handle 1 is located in the handle cavity 24 of the main gear 2. On both sides of the main gear 2, there are first bearings 3 and second bearings 4 that mate with it. This allows the main gear to rotate freely under the action of the two bearings, achieving zero friction. The first bearing 3 mates with the handle cavity 24 of the main gear 2, while the second bearing 4 mates with the outer diameter bearing surface cavity 21 of the main gear 2. The rotating component 4 is fixed to the main gear via the rotating component retaining groove 22. like Figure 2 , Figure 3 and Figure 9 As shown, the outer diameter of the first bearing is fixed on the base 6, and the inner diameter of the second bearing 4 is fixed on the cover plate 7. The whole structure forms a rotating structure that is fixed by bearings at both the top and bottom, and the handle 1 is detachable.

[0023] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0024] In the description of this application, it should be noted that the terms "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product is in use. They are used only for the convenience of describing this application and for 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 application. Furthermore, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0025] Furthermore, terms such as "horizontal" and "vertical" do not imply that components must be absolutely horizontal or vertical, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0026] In the description of this application, it should also be noted that, unless otherwise expressly specified and limited, the terms "set up," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0027] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
