Technical Field

[0001] The utility model relates to the technical field of door hinges, in particular to a hinge base and a hinge. Background Art

[0002] A hinge is a mechanical device that connects two objects and allows them to rotate relative to each other. In the field of building hardware, it is mainly applied to the rotating connection system of door leaf - door frame. At the same time, it is also widely used in window structures, folding furniture and industrial equipment.

[0003] In the prior art, the utility model patent with the patent publication number CN222121250U discloses a three - point positioning installation hardware hinge base, which includes a base body. The left and right sides of the base body are respectively provided with a first connection seat and a second connection seat, and the tail of the base body is provided with a third connection seat. The first connection seat, the second connection seat and the third connection seat are distributed in a "pin" shape, and mounting holes are opened on the first connection seat, the second connection seat and the third connection seat. Fixing screws pass through the mounting holes and are fixedly connected to the board. In the disclosed technical solution, there is an upward notch at the connection between the third connection seat and the side plate of the base body, so that the end of the side plate far from the base body can be bent downward to form an upper overlapping plate and a lower overlapping plate that overlap up and down. The setting of the notch may cause the upward bending resistance at the connection between the third connection seat and the base body to be relatively low, which has a certain impact on the overall strength and service life of the hinge base. Summary of the Utility Model

[0004] Aiming at the defects in the prior art, the present invention provides a hinge base and a hinge to improve the bending resistance and stability of the hinge base and extend the service life of the hinge base.

[0005] In the first aspect, the hinge base device provided by the present invention includes a base body. The base body includes a top plate and two side plates. The feature is that an installation structure is provided at the tail of the base body.

[0006] The installation structure includes connecting parts respectively extending from the tails of the two side plates. On the side of the two connecting parts far from the top plate, there are bending parts that are bent inward and overlapped. The bending parts are provided with mounting holes for fasteners to pass through, and a notch is opened at the position of the connecting parts close to the bending parts.

[0007] Optionally, the connecting part is provided with a reinforcing rib corresponding to the notch.

[0008] Optionally, along the extending direction of the connecting part, the size of the reinforcing rib is larger than the size of the notch.

[0009] Optionally, the reinforcing rib is triangular.

[0010] Optionally, the reinforcing rib protrudes from one side of the two connecting portions opposite each other.

[0011] Optionally, the inner edge of the mounting hole is provided with a edging, and the edging extends through the mounting hole.

[0012] Optionally, the edging is formed by extending downward from the inner edge of the mounting hole of the upper curved portion.

[0027] The embodiments of the technical solution of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the technical solution of the present invention and are therefore intended to limit the scope of protection of the present invention.

[0028] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application should have the ordinary meaning as understood by one of ordinary skill in the art to which this invention pertains.

[0029] In this application, unless otherwise expressly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0030] like Figure 1-4 As shown, the hinge base 1 provided by this utility model includes a base body 10, which includes a top plate 11 and two side plates 12. The rear end of the base body 10 is provided with a mounting structure 13. The mounting structure 13 includes connecting portions 131 extending from the rear ends of the two side plates 12 respectively. The two connecting portions 131 are provided with inwardly bent and stacked curved portions 132 on the side away from the top plate 11. The curved portions 132 are provided with mounting holes 133 for fasteners to pass through. The connecting portions 131 are provided with notches 134 near the curved portions 132.

[0031] Since the hinge and hinge base are mainly manufactured using stamping, the notch 134 facilitates the processing of the bent portion 132, preventing gaps between the two overlapping bent portions 132 due to poor bending. This ensures a tight fit between the two bent portions 132, which is beneficial for the fixation and stability of the hinge base 1. Simultaneously, the reduced strength at the joint between the bent portion 132 and the base body 10 caused by the notch 134 is compensated for by the connecting portion 131. That is, the bent portion 132 is connected to the base body 10 through the connecting portion 131. The connecting portion 131 enhances the connection strength between the bent portion 132 and the base body 10, preventing deformation or even cracking of the hinge base 1 due to long-term stress, and avoiding the problem of low upward bending strength at the notch due to weak side structure.

[0032] Specifically, the connecting part 131 is integrally formed with the base body 10, and the bent part 132 is integrally stamped with the connecting part 131. The integral forming process can simplify the production process and reduce the processing cost.

[0033] Specifically, the connecting part 131 can be triangular, which has high stability and can further enhance the connection strength between the bent part 132 and the base body 10.

[0034] Furthermore, a reinforcing rib 135 is provided in the connecting portion 131 corresponding to the notch 134. The reinforcing rib 135 can further compensate for the strength deficiency at the notch 134, solve the stress concentration problem caused by the lack of material at the notch 134, and avoid local deformation caused by the presence of the notch 134. Moreover, the coverage area of ​​the reinforcing rib 135 is preferably larger than the area of ​​the notch 134, that is, along the extension direction of the connecting portion 131, the size of the reinforcing rib 135 is larger than the size of the notch 134. This can improve the force transmission efficiency and disperse the stress to a wider area, thus maximizing the strengthening effect of the reinforcing rib 135 on the strength of the connecting portion 131.

[0035] Preferably, the reinforcing rib 135 is triangular. Utilizing the inherent geometric stability of a triangle, its reinforcing effect on the connection 131 can be further enhanced.

[0036] It is understandable that the shape of the reinforcing rib 135 can also be other shapes, such as circles, rectangles, etc.

[0037] Furthermore, the reinforcing rib 135 is integrally stamped from the connecting part 131, and preferably stamped inward, so that the stamped reinforcing rib 135 protrudes inward, which will not hinder the installation space of the hinge base 1 and other components, while simplifying the stamping process.

[0038] Furthermore, the inner edge of the mounting hole 133 is provided with a retaining edge 136, which extends through the mounting hole 133. The retaining edge 136 can limit the relative movement that may occur between the two stacked curved portions 132 under stress, prevent the two curved portions 132 from misaligning, and make the two stacked curved portions 132 form a whole in the radial direction along the mounting hole 133, thereby increasing the strength of the mounting structure 13 and preventing wear on the edge of the mounting hole 133.

[0039] Furthermore, the edging 136 extends downward from the inner edge of the mounting hole 133 of the upper curved portion 132, which is easier to stamp than extending upward. At the same time, the fastener passes through the mounting hole 133 to fix the hinge base 1. The edging 136 extends from top to bottom, which can make the two curved portions 132 stacked on top of each other fit more tightly during the fixing process, making the installation of the hinge base 1 more secure.

[0040] Furthermore, the opening of the edging 136 is enlarged along the direction in which the edging 136 extends. This better restricts the relative movement between the two curved portions 132, and in particular, it restricts the axial displacement between the two curved portions 132 along the mounting hole 133.

[0041] Specifically, the edging 136 can be formed by stamping the upper curved part 132. The opening of the edging 136 is enlarged by reverse stamping, which increases the opening of the edging 136. This reliably restricts the radial and axial displacement of the two curved parts 132 stacked on the upper and lower layers along the mounting hole 133, and makes them more firmly integrated.

[0042] Furthermore, mounting grooves 137 are provided on both sides of the lower curved portion 132 perpendicular to the connecting portion 131. The mounting grooves 137 are used to connect with the component to be installed. The hinge base 1 is fixed to the component to be installed through the mounting grooves 137 to ensure the installation stability of the hinge.

[0043] Furthermore, both side plates 12 of the base body 10 are provided with strip holes 121, which are arranged opposite to each other. The damper is disposed in the space enclosed by the top plate 11 and the side plates 12. During the installation of the damper, the pin of the damper extends out from the strip hole 121 and can slide within the strip hole 121, which facilitates the matching of the pin of the damper with the shaft hole of the hinge arm 3, thus facilitating the installation of the damper.

[0044] Furthermore, a boss 122 is provided on one side of the two side plates 12 of the base body 10. The boss 122 protrudes inward and can prevent the damper from shaking, thereby improving the durability of the damper and the hinge base 1.

[0045] like Figure 5As shown, this utility model also provides a hinge, including a hinge base 1, a hinge cup 2 and a hinge arm 3. The hinge base 1 is fixedly connected to the hinge arm 3, and the hinge cup 2 is rotatably connected to the hinge arm 3. For the specific structure of the hinge base 1, please refer to the above text. To save space, it will not be described again here.
