Anti-loosening spectacle frame hinge structure

Abstract

The utility model relates to the technical field of mirror bracket hinges, and discloses an anti-loosening mirror bracket hinge structure which comprises a pile head, a bolt A, a bolt B and an annular nut which are mutually combined to play a role, and mechanical interlocking is formed and a loosening gap is eliminated by utilizing thread size difference of the bolt A and the annular nut and threaded connection and meshing of the bolt B, so that an anti-loosening effect is achieved. Furthermore, the anti-loosening effect can be realized without adding a rubber gasket in the hinge; and meanwhile, due to the interlocking structure, the fastening among the bolt A, the bolt B and the annular nut cannot be excessively influenced by the opening and closing actions when the glasses are worn.

Description

Technical Field

[0001] This utility model relates to the field of eyeglass frame hinges, specifically an eyeglass frame hinge structure that prevents loosening. Background Technology

[0002] Most eyeglass frame hinges are currently movable connection structures composed of multiple precision parts, usually located on the left and right sides of the frame (at the head), connecting the frame and the temples. Their core function is to enable the opening and closing rotation of the temples, while ensuring stability and comfort when wearing them.

[0003] In conclusion, the existing frame hinge connection structure still has many drawbacks, summarized as follows:

[0004] ① The hinge fixing screws are prone to loosening during long-term use;

[0005] ② During the hinge fixing process, rubber washers are used to delay loosening. Although this can reduce loosening to some extent, the rubber will age over time. Furthermore, if the fixing screws are tightened too much during manual assembly, the rubber washers will age faster and affect their use. Utility Model Content

[0006] To address the shortcomings of existing technologies, this invention provides a non-loosening eyeglass frame hinge structure to solve the aforementioned problems.

[0007] To achieve the above objectives, this utility model is implemented through the following technical solution.

[0008] A non-loosening eyeglass frame hinge structure includes a post head, bolt A, bolt B, and a ring nut.

[0009] The pile head is provided with limiting countersunk platform A and limiting countersunk platform B, and the bolt B includes an internal threaded hole and an interlocking external threaded post.

[0010] The thread diameter on bolt A matches the thread diameter of the internal threaded hole. Bolt A passes through the annular nut and is threadedly connected to the internal threaded hole. The annular nut is engaged with the limiting countersunk platform A.

[0011] The thread diameter of the interlocking external threaded post is adapted to the thread diameter of the ring nut. The interlocking external threaded post is threadedly connected to the ring nut, and bolt B is embedded in the limiting countersunk platform B. The difference in thread size between bolt A and the ring nut and the thread connection of bolt B are used to form a mechanical interlock, eliminating loosening gaps and achieving the effect of preventing loosening. Furthermore, it can achieve the effect of preventing loosening without adding a rubber washer to the hinge. At the same time, the interlocking structure ensures that the opening and closing action when wearing glasses will not affect the tightness between bolt A, bolt B, and ring nut too much.

[0012] Preferably, the bolt A has a cross groove on its upper surface.

[0013] Preferably, a slot is provided above the bolt B.

[0014] Compared to existing technologies, this utility model discloses an anti-loosening frame hinge structure, including a post, bolt A, bolt B, and a ring nut. These four components work together to form a mechanical interlock by utilizing the difference in thread size between bolt A and the ring nut, which engages with the thread of bolt B to eliminate loosening gaps and achieve an anti-loosening effect. Furthermore, it achieves anti-loosening without adding rubber washers to the hinge. At the same time, the interlocking structure ensures that the opening and closing action when wearing glasses does not significantly affect the tightness between bolt A, bolt B, and the ring nut.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] A hinge structure for preventing loosening of eyeglass frames includes a post head 1, bolt A2, bolt B3, and an annular nut 4. The post head 1 is provided with a limiting countersunk platform A11 and a limiting countersunk platform B12. The bolt B3 includes an internal threaded hole 31 and an interlocking external threaded post 32.

[0020] The thread diameter on the bolt A2 is matched with the thread diameter of the internal threaded hole 31. The bolt A2 passes through the annular nut 4 and is threadedly connected to the internal threaded hole 31. The annular nut 4 is locked on the limiting countersunk platform A11. The thread diameter of the interlocking external threaded post 32 is matched with the thread diameter of the annular nut 4. The interlocking external threaded post 32 is threadedly connected to the annular nut 4, and the bolt B3 is embedded in the limiting countersunk platform B12.

[0021] The bolt A2 has a cross groove on its upper part, and the bolt B3 has a slotted groove on its upper part.

[0022] The temple is placed in the head 1. Bolt B3 passes through the head 1 and the temple, and is connected to the ring nut 4. It is further tightened and fixed by the interlocking external thread post 32 to complete the initial fixing work. Then, bolt A2 passes through the ring nut 4 and is threaded into the internal threaded hole 31 to complete the secondary locking. The difference in thread size between bolt A2 and ring nut 4 and the thread connection of bolt B3 are used to form a mechanical interlock and eliminate loose gaps.
