[0024] This invention provides the following description with reference to the accompanying drawings to aid in a comprehensive understanding of the various embodiments of the invention as defined by the claims and their equivalents. The description includes various specific details to aid understanding, but these details should be considered exemplary only. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the various embodiments described herein without departing from the scope and spirit of the invention.
[0025] In the description of this utility model, the orientation descriptions, such as up, down, front, back, left, right, etc., are based on the orientation or positional relationship shown in the accompanying drawings. 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.
[0026] It should be understood that when one element (e.g., the first element) is “connected” to another element (e.g., the second element), the element may be directly connected to the other element, or there may be an intervening element (e.g., the third element) between the element and the other element.
[0027] An embodiment of this utility model provides a rotating shaft structure with built-in components, such as... Figures 1-3As shown, the device includes an outer pivot 100 and an inner component 200 made of metal. The outer pivot 100 can be made of traditional ABS material or other materials. The outer pivot 100 includes an outer base 110 and an outer shaft 120 integrally formed with the outer base 110. Specifically, the outer base 110 and outer shaft 120 can be integrally formed by injection molding or other methods. The inner component 200 includes an inner base 210 and an inner shaft 220 integrally formed with the inner base 210. Specifically, the inner base 210 and inner shaft 220 can be integrally formed by casting or other methods. The inner base 210 is embedded inside the outer base 110, and the inner shaft 220 is embedded inside the outer shaft 120. Therefore, the built-in component 200 is embedded inside. Since the built-in component 200 is made of metal, its structural strength is greater. It provides effective support to both the outer base 110 and the outer shaft 120 from the inside, which can improve the overall structural strength of the hinge structure. The hinge structure is not only suitable for lighter doors, but also less prone to damage or breakage when used for heavier doors, thus broadening the application range of the hinge structure.
[0028] In this embodiment, the built-in component 200 can be manufactured first, and then the built-in component 200 can be placed into the corresponding mold for secondary molding. The molding material of the outer rotating shaft component 100 wraps the built-in component 200, and the inner base 210 can be embedded in the interior of the outer base 110, and the inner shaft body 220 can be embedded in the interior of the outer shaft body 120, so as to obtain the rotating shaft structure with built-in component in this embodiment.
[0029] In some embodiments, the surface of the outer base 110 is provided with a through first mounting hole 111, and the surface of the inner base 210 is provided with a through second mounting hole 211, the first mounting hole 111 and the second mounting hole 211 being aligned. The first mounting hole 111 and the second mounting hole 211 are used to fix the entire rotating shaft structure in a designated position. Specifically, screws or other connecting parts can be passed through the first mounting hole 111 and the second mounting hole 211 and then fixed in the designated position.
[0030] The first mounting hole 111 and the second mounting hole 211 are aligned so that after the connector is inserted into the first mounting hole 111, it can pass smoothly through the second mounting hole 211. Specifically, the first mounting hole 111 and the second mounting hole 211 can be set coaxially.
[0031] Furthermore, the inner wall of the first mounting hole 111 is integrally formed with a covering ring 112. The forming material of the covering ring 112 can be the same as that of the outer rotating shaft 100. The covering ring 112 covers at least a portion of the inner wall of the second mounting hole 211. This can strengthen the connection between the inner base 210 and the outer base 110, and the hole wall of the second mounting hole 211 provides a certain degree of protection, reducing damage to the inner base 210 and making the inner base 210 less prone to rust.
[0032] In some embodiments, the surface of the outer base 110 is further provided with two positioning strips 130, which are located on both sides of the first mounting hole 111. During installation, the positioning strips 130 can be inserted into the mounting groove of the profile, and the positioning strips 130 can abut against the inner wall of the mounting groove, thereby positioning the outer base 110 and facilitating the connection between the first mounting hole 111 and the threaded hole on the profile for quick installation. At the same time, the positioning strips 130 also serve as a limit, making it difficult for the outer base 110 to move laterally relative to the profile, thus allowing the outer base 110 to be more stably fixed to the profile.
[0033] Furthermore, the surface of the outer base 110 is also provided with reinforcing ribs 140. The two ends of the reinforcing ribs 140 are respectively connected to two positioning strips 130. The reinforcing ribs 140 can provide support for the two positioning strips 130 from the inside, strengthen the structural strength of the two positioning strips 130, make the two positioning strips 130 less likely to bend or break, and extend their service life.
[0034] In some embodiments, such as Figure 1 , Figure 4 and Figure 5 As shown, a support cylinder 150 is also provided on the surface of the outer base 110. The support cylinder 150 is sleeved on the outside of the outer shaft 120. The end face of the support cylinder 150 away from the outer base 110 has two guide surfaces 151 that are inclined in a relatively horizontal direction, such as... Figure 1 As shown, since the support cylinder 150 is a cylindrical structure, the guide surface 151 can be similar to a fan shape, and the two guide surfaces 151 are connected to each other at their highest points.
[0035] The outer shaft 120 is inserted into the pivot sleeve on the door body. The pivot sleeve abuts against the guide surface 151. Since the guide surface 151 is inclined, it has a highest point and a lowest point. When the door body rotates, the pivot sleeve moves along the guide surface 151. As the height of the guide surface 151 changes, the pivot sleeve is lifted upward accordingly, and the door body will also be lifted upward. The door body can then move away from the ground, reducing the resistance to rotation and making it easier to open and close the door.
[0036] In this embodiment, the support cylinder 150 can be integrally formed with the outer base 110 and the outer shaft 120.
[0037] Furthermore, the pivot structure of this embodiment also includes a pivot sleeve 160, which is sleeved on the outside of the outer shaft body 120. The bottom of the pivot sleeve 160 has two support surfaces 161 that are adapted to the two guide surfaces 151 respectively. The two support surfaces 161 are inclined relative to the horizontal direction, and the highest points of the two support surfaces 161 are connected to each other. The two support surfaces 161 abut against the two guide surfaces 151 respectively. During the rotation of the pivot sleeve 160, the two support surfaces 161 slide along the two guide surfaces 151 respectively. When the lowest point of the support surface 161 is at the highest point of the guide surface 151, the door will be raised.
[0038] Furthermore, each of the two support surfaces 161 has a groove 162 at its lowest point. When the lowest points of the two support surfaces 161 of the rotating bushing 160 are both above the connection point of the two guide surfaces 151, the two ends of the connection point of the two guide surfaces 151 are respectively inserted into the grooves 162 of the two support surfaces 161.
[0039] Since both the support surface 161 and the guide surface 151 are inclined, and the connection between the two guide surfaces 151 is a very narrow linear structure, the support surface 161 can easily slip off from the highest point of the guide surface 151. In this embodiment, by setting a groove 162, the connection between the guide surfaces 151 is inserted into the groove 162, making it less likely to fall out of the groove 162 under its own weight, so that the door can remain in a raised state.
[0040] In some embodiments, the built-in component 200 is made of stainless steel, which has high structural strength and is not easy to rust. Of course, the built-in component 200 can also be made of other metal materials such as aluminum alloy.
[0041] The hinge structure in the above embodiment can be set at the bottom of the door to form a lower hinge structure, or at the top of the door to form an upper hinge structure.
[0042] like Figure 1 As shown, when the shaft structure of the above embodiment is used as a lower shaft structure, the outer base 110 is disposed below the outer shaft body 120, and the outer shaft body 120 extends upward.
[0043] like Figure 6 As shown, when the shaft structure of the above embodiment is used as an upper shaft structure, the outer base 110 is disposed above the outer shaft body 120, and the outer shaft body 120 extends downward.
[0044] The terms and words used in the foregoing description and claims are not limited to their literal meaning, but are merely used by the applicant to enable a clear and consistent understanding of the present invention. Therefore, those skilled in the art should understand that the foregoing description of various embodiments of the present invention is for illustrative purposes only, and not intended to limit the present invention as defined by the appended claims and their equivalents.
