Description

Technical Field

[0001] The utility model relates to the technical field of microscopes, in particular to a foldable jewelry magnifying glass. Background Art

[0002] In jewelry appraisal, a magnifying glass is often used to see the jewelry more clearly.

[0003] The folding shaft is used in the prior art jewelry magnifiers. The folding shaft includes two basic connection forms, including mortise connection and screw fixing connection. The mortise or screw position can be observed in the appearance of the existing folding jewelry magnifiers using the above fixing methods. However, both the mortise and screw fixing folding connection methods have the problem of folding looseness, and the structure assembled by rivets cannot be restored after loosening. In addition, because it is not flat, the magnifier product also has the problem of poor feel when used.

[0004] In the prior art, when making a folding bracket for a jewelry magnifier, according to the designed folding tightness, it is necessary to rely on a press machine to press the rivets or directly rotate the screws and holes to adjust the folding tightness. The tightness of the above-mentioned machined folding connection structure cannot be accurately controlled and is very unreliable. The tightness is the source of the damping feeling, and the external manifestation is that it starts to loosen after being folded hundreds of times. When using rivets as connecting parts, this loosening cannot be restored.

[0005] In addition, magnifying glasses with mortise-type connection and screw-fixed connection will also have some parts of screws or mortise left on the appearance, which makes the design not beautiful enough. Summary of the invention

[0006] Based on this, in order to solve the above-mentioned problems in traditional technologies, the utility model proposes a foldable jewelry magnifier with a more beautiful design and a better feel for use. The folding and rotating damping is controlled by the friction between the damping member and the rotating shaft. The damping feeling is not affected after tens of thousands of foldings, and the folding magnifier does not loosen and is durable.

[0007] The utility model relates to a foldable jewelry magnifier, comprising a bracket and a magnifier assembly rotatably accommodated in the bracket, the bracket comprising an upper cover and a lower cover, the upper cover and the lower cover are tightly mounted via a connecting column and a rotating shaft, the magnifier assembly comprises a lens and a lens frame, a rotating shaft cavity is formed in the lens frame, the rotating shaft is accommodated and installed in the rotating shaft cavity, so that the magnifier assembly can be rotatably connected to the bracket and buckled on the connecting column, the lens frame is provided with an accommodating cavity communicated with the rotating shaft cavity, at least one damping member for acting on the rotating shaft is provided in the accommodating cavity, and is used to generate required rotation damping due to interference between the damping member and the rotating shaft.

[0010] In order to make the structure design lighter and more compact, one end of the rotating shaft with interference fit and the third shaft column are installed together in the upper installation cavity, and the other end of the rotating shaft with interference fit and the fourth shaft column are installed together in the lower installation cavity.

[0011] In the damping rotation design, at least one of the upper chamber or the lower chamber of the accommodating chamber is equipped with two or more damping members; or two or more damping members are installed in both the upper chamber and the lower chamber, and the damping members are rubber rings.

[0031] The lens frame is provided with a receiving chamber C2 surrounding the rotating shaft 3 and communicating with the rotating shaft chamber C1, and the receiving chamber C2 is communicated with the rotating shaft chamber C1. The receiving chamber C2 is provided with at least one damping member, such as a rubber ring or a rubber pad, for acting with the rotating shaft 3, for generating the required rotation damping due to interference between the damping member and the rotating shaft 3. In this embodiment, rubber rings 91 and 94 are used as examples for explanation.

[0032] The lens frame of the upper and lower structures comprises a first sheet body 5 and a second sheet body 8 which are buckled together to form a lens cavity and a shaft cavity.

[0033] Please refer to Figure 4 The shaft cavity C1 passes through the first sheet 5 and the second sheet 8, and contains the rotating shaft 3. The connecting structure of the rotating shaft 3 and the upper cover 2 is arranged at the upper part of the shaft cavity C1; the connecting structure of the rotating shaft 3 and the lower cover 1 is also arranged at the lower part of the shaft cavity C1, so as to realize the surface seamless installation of the bracket A and the magnifying glass assembly C and the lightness and compactness of the overall design.

[0034] The accommodating cavity includes an upper cavity 83 and a lower cavity 52. ​​The rotating shaft cavity C1 passes through the first sheet 5 and the second sheet 8, and includes a mounting cavity 82 formed on the first sheet 5 for accommodating the connecting structure between the rotating shaft 3 and the upper cover 2, and also includes a lower mounting cavity 51 formed on the second sheet 8 for accommodating the connecting structure between the rotating shaft 3 and the lower cover 1.

[0035] The first sheet 5 is provided with a first lens window 54, a lower mounting cavity 51 and a lower chamber 52. The lower mounting cavity 51 and the lower chamber 52 are separated by a partition, and the lower mounting cavity 51 and the lower chamber 52 are both connected to the shaft cavity C1. The second sheet 8 is provided with a second lens window 84, an upper chamber 83 and an upper mounting cavity 82. The upper mounting cavity 82 and the upper chamber 83 are separated by a partition, and the upper mounting cavity 82 and the upper chamber 83 are both connected to the shaft cavity C1.

[0036] like Figure 5 As shown, the first sheet 5 is provided with an outer positioning edge 57 at the top of the first lens window 54. The second sheet 8 is provided with an inner positioning edge 85 at the bottom of the second lens window 84. The inner positioning edge 85 and the outer positioning edge 57 are engaged with each other.

[0037] In this embodiment, the lens 7 is a three-layer glued lens and a magnifying lens.

The third shaft column 21 defines a third interference hole 211. The fourth shaft column 15 defines a fourth interference hole 152.

[0040] During assembly, the rotating shaft 3 passes through the rotating shaft cavity C1, and one end of the rotating shaft 3 is installed in the third interference hole 211 of the third shaft column 21 by interference fit. The other end of the rotating shaft 3 is installed in the fourth interference hole 152 of the fourth shaft column 15 by interference fit. In order to make the structural design lighter and more compact, one end of the rotating shaft 3 and the third shaft column 21 are installed together in the upper installation cavity 82 by interference fit, and the other end of the rotating shaft 3 and the fourth shaft column 15 are installed together in the lower installation cavity 51 by interference fit.

[0041] This embodiment uses interference to create a sense of rotational damping.

[0044] In this embodiment, a clamping protrusion B is provided on the outer wall of the lens frame. A toggle groove B1 is provided in the middle of the clamping protrusion B, and the toggle groove B1 produces a good touch feeling when the user unfolds the magnifying glass assembly C. When the magnifying glass assembly C is folded and retracted into the bracket A, the clamping protrusion B is clamped and fixed with the connecting column 4, and the clamping protrusion B extends from the first sheet 5 to the second sheet 8.

[0045] In addition, a through hole 42 for inserting a lanyard is provided in the connecting column 4 of this embodiment.
