DETAILED DESCRIPTION OF THE EMBODIMENTS

In addition, features defined as "first", "second" may explicitly or implicitly include one or more of such features. In the description of the present invention, unless otherwise specified, the meaning of "a plurality" is two or more.

[0023] In the description of the present invention, it should be noted that unless otherwise clearly specified and defined, the terms "mounted", "arranged", "connected" should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0024] Referring to Figure 1 、 Figure 2 and Figure 3 , the present invention discloses a magnification lens mounting bracket, which includes a fixed seat 100, a flipping seat 200, and a flipping spring 300. The fixed seat 100 and the flipping seat 200 are rotatably connected together. Among them, the fixed seat 100 is provided with a first mounting hole 101, the flipping seat 200 is provided with a second mounting hole 201, and the two ends of the flipping spring 300 are respectively connected to the first mounting hole 101 and the second mounting hole 201.

[0025] In the normal state, the elastic force of the flipping spring 300 drives the flipping seat 200 to overlap on the upper surface of the fixed seat 100. At this time, the fixed seat 100 and the flipping seat 200 are parallel. Under the action of an external force, by applying an external force to the flipping seat 200 to overcome the elastic force of the flipping spring 300, the flipping seat 200 can be driven to rotate away from the fixed seat 100. During the rotation, the distance between the first mounting hole 101 and the second mounting hole 201 first shortens and then increases. During the process of the distance between the first mounting hole 101 and the second mounting hole 201 shortening, the flipping spring 300 is compressed to generate a greater elastic force, making the flipping seat 200 tend to move towards the fixed seat 100. Under the action of the external force overcoming the elastic force, when the flipping seat 200 rotates to a certain angle, the distance between the first mounting hole 101 and the second mounting hole 201 begins to increase, and the elastic force generated by the flipping spring 300 being compressed before is released, and it drives the flipping seat 200 to move away from the fixed seat 100, thereby realizing the automatic flipping of the flipping seat 200 after applying force to a certain angle.

[0026] Furthermore, a limiting structure is also provided between the fixed seat 100 and the flipping seat 200, and the limiting structure is used to limit the rotation amplitude of the flipping seat 200.

[0027] The magnifying glass mounting bracket of the embodiment of the present invention has at least the following beneficial effects: The magnifying glass mounting bracket of the present invention realizes the automatic locking and fixing of the flipping seat and the fixed seat through the flipping spring. At the same time, only by applying an external force to overcome the elastic force of the flipping spring to control the rotation of the flipping seat, after rotating to a certain angle, the force application direction of the flipping spring can be changed to drive the flipping seat to complete the flipping action, and the flipping angle of the flipping seat is limited by means of the limiting structure, realizing the locking and flipping functions between the flipping seat and the fixed seat, and having the advantages of simple structure and convenient operation.

[0028] Reference Figure 2 、 Figure 3 and Figure 4 With reference to

[0029] Reference Figure 3 and Figure 4, the limiting structure includes a limiting groove 401 circumferentially arranged on the outer surface of the rotating shaft 400 along the circumferential direction of the rotating shaft 400. The cross-section of the limiting groove 401 is arc-shaped. It further includes a ball 500 clamped on the fixed seat 100. The size of the ball 500 is adapted to the limiting groove 401, and one side of the ball 500 abuts against the inside of the limiting groove 401. During the rotation of the flipping seat 200 relative to the fixed seat 100, the rotating shaft 400 rotates together with the flipping seat 200, causing the ball 500 to move relative to the limiting groove 401. When the ball 500 moves relative to the end of the limiting groove 401, the movement stops, thereby restricting the rotation of the rotating shaft 400, and further restricting the rotation amplitude of the flipping seat 200 relative to the fixed seat 100.

[0030] Reference Figure 3 and Figure 4 , a limiting hole 111 is arranged inside the fixed bushing 110. The aperture of the limiting hole 111 is adapted to the ball 500. The limiting hole 111 is used for the installation of the ball 500. The ball 500 is placed inside the limiting hole 111, and the upper side of the ball 500 protrudes from the limiting hole 111 and extends into the limiting groove 401, thereby ensuring the stable cooperation between the ball 500 and the limiting groove 401.

[0031] Reference Figure 4 , the arc angle of the limiting groove 401 is 90°. By setting the limiting groove 401 with a 90° arc angle, the rotation angle of the rotating shaft 400 is restricted to 90°, realizing the flipping of the flipping seat from 0 to 90°.

[0032] It should be noted that the arc angle of the limiting groove 401 of the present invention is not limited to 90° in this embodiment. The arc angle of the limiting groove 401 can be set to other angles according to the actual rotation amplitude requirements.

[0033] Reference Figure 1 and Figure 2 , the first mounting hole 101 is arranged on the fixed bushing 110. When the fixed seat 100 is in a horizontal state, the central angle between the first mounting hole 101 and the horizontal line where the rotating shaft 400 is located is 45°. When the flipping seat 200 rotates around the fixed seat 100 through the rotating shaft 400, when the first mounting hole 101, the second mounting hole 201 and the axis of the rotating shaft 400 are on the same straight line, the distance between the first mounting hole 101 and the second mounting hole 201 reaches the shortest, and the elastic force of the flipping spring 300 reaches the maximum value, thereby driving the flipping seat 200 to flip away from the fixed seat 100.

[0034] It can be understood that when the flipping base 200 is flipped under the action of an external force, before the flipping base 200 rotates 45°, the flipping spring 300 exerts a force on the flipping base 200 towards the fixed base 100. And only by driving the flipping base 200 to rotate 45° around the fixed base 100 with an external force, the flipping spring 300 can be made to exert a force on the flipping base 200 in the direction away from the fixed base 100, so as to realize the automatic flipping of the flipping base 200 after flipping 45°.

[0035] Reference Figure 1 and Figure 2 , the first mounting hole 101 and the second mounting hole 201 are both parallel to the setting direction of the rotating shaft 400. At the same time, the middle part of the flipping spring 300 is a spiral part, and both ends of the flipping spring 300 are bent towards the axis direction of the spiral part and respectively inserted into the first mounting hole 101 and the second mounting hole 201 to ensure the stable connection of the flipping spring 300 with the flipping base 200 and the fixed base 100, and to ensure that the flipping spring 300 can generate elastic deformation and elastic force along with the rotation of the flipping base 200.

[0036] Reference Figure 2 and Figure 3 , a plug-in member 120 is arranged in the fixed bushing 110, one end of the rotating shaft 400 is inserted on the plug-in member 120, the first mounting hole 101 is arranged on the outer peripheral side of the plug-in member 120 along the axis direction of the rotating shaft 400, and the first plugging hole is formed by enclosing the plug-in member 120 and the fixed bushing 110.

[0038] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and purposes of the present invention, and the scope of the present invention is defined by the claims and their equivalents.
