DETAILED DESCRIPTION

[0024] The utility model will be explained in detail in combination with the drawings. The figure is a simplified schematic diagram, and only the basic structure of the utility model is schematically shown, so it only shows the structure related to the utility model.

[0025] Please refer to Figures 1-7 The utility model provides a kind of easy-to-assemble reading and writing mirror, including mirror frame 10, lens 20 and temple 30, lens 20 has two, and is fixedly installed on mirror frame 10, temple 30 has two, and is respectively detachably installed on mirror frame 10 opposite side.The lens 20 adopts the structure that prism and convex mirror are combined to prevent myopia, and the lens 20 belongs to prior art, and will not be repeated here.

[0026] The end of temple 30 is protrudingly formed with insertion column 31, and insertion column 101 is matched and inserted in slot 101, so that the connecting relationship between temple 30 and mirror frame 10 is realized.The cross section of slot 101 is non-circular structure, in the embodiment, the cross section shape of slot 101 is rectangle, when insertion column 31 is matched and connected with slot 101, insertion column 31 will not rotate relative to slot 101, so as to ensure the position stability of temple 30.

[0027] In the embodiment, the mirror frame 10 is provided with an arc-shaped elastic sheet 40, and the protruding part of the elastic sheet 40 abuts against the outer surface of the insertion column 31. Before the insertion column 31 is installed, the elastic sheet 40 is deformed under the elastic force of the elastic sheet 40, and the protruding part on the elastic sheet 40 is located in the insertion slot 101. When the insertion column 31 is gradually inserted into the insertion slot 101, the outer surface of the insertion column 31 pushes against the protruding part of the elastic sheet 40 and extrudes the elastic sheet 40. The elastic force generated by the extruded and deformed elastic sheet 40 acts on the insertion column 31, which can pre-tighten the installation of the insertion column 31 and effectively prevent the insertion column 31 from being easily pulled out of the insertion slot 101. The elastic sheet 40 is made of stainless steel.

[0028] As a preferred embodiment, a groove 102 is formed in the side wall of the mirror frame 10 and communicates with the insertion slot 101, and the elastic sheet 40 is installed in the groove 102. The two ends of the elastic sheet 40 are fixedly connected to the two groove walls opposite to each other. Preferably, the elastic sheet 40 is connected to the mirror frame 10 by welding. By providing the groove 102, the elastic sheet 40 can be fixed to the mirror frame 10. In actual use, a plug (not shown in the figure) can be installed at the end of the groove 102 away from the insertion column 101 to prevent dust and other impurities from entering the groove 102.

[0029] Further, the side wall of the insertion column 31 is recessed with a clamping groove 310 which is aligned with the elastic sheet 40. When the insertion column 31 is inserted into the insertion slot 101 and the clamping groove 310 is aligned with the protruding part of the elastic sheet 40, the protruding part of the elastic sheet 40 will not be clamped into the clamping groove 310, thereby more effectively locking the insertion column 31. At the same time, the cooperation between the elastic sheet 40 and the clamping groove 310 can position the installation of the insertion column 31, which is convenient for the user to quickly and accurately install in place.

[0030] The opposite sides of the mirror frame 10 extend outwardly to form a connecting rod 11, which is substantially L-shaped. The insertion slot 101 is formed at the end of the connecting rod 11 away from the mirror frame 10. In the embodiment, the connecting rod 11 includes a first rod segment 111 and a second rod segment 112 connected to each other. The first rod segment 111 and the second rod segment 112 are smoothly connected to each other. The end of the first rod segment 111 away from the second rod segment 112 is fixedly connected to the mirror frame 10. The insertion slot 101 is formed at the end of the second rod segment 112 away from the first rod segment 111. The elastic sheet 40 is installed on the second rod segment 112 of the connecting rod 11, and the groove 102 is formed in the side wall of the second rod segment 112.

[0031] The temple 30 comprises a fixed section 32 and a folding section 33, the folding section 33 is rotatably connected with the fixed section 32, the length of the folding section 33 is far less than the length of the folding section 33, the plug post 31 is protruded on the end of the fixed section 32 away from the folding section 33. In the embodiment, the fixed section 32 and the second rod section 112 are both cylindrical structure, the fixed section 32 is provided with a positioning flange 321 on the outer wall close to the second rod section 112 and extending outward along the radial direction of the fixed section 32, the outer part of the fixed section 32 is movably sleeved with a threaded sleeve 51, the positioning flange 321 is located in the threaded sleeve 51, the outer wall of the second rod section 112 is provided with external threads matched with the internal threads of the threaded sleeve 51. In use, after the plug post 31 is inserted into the plug slot 101, the user can rotate the threaded sleeve 51 so that the internal and external threads are matched with each other, at the same time, the threaded sleeve 51 is partially sleeved on the outer part of the second rod section 112. Continue to rotate the threaded sleeve 51 so that the end side wall of the threaded sleeve 51 abuts against the positioning flange 321, at this time, the threaded sleeve 51 cannot continue to rotate, the threaded sleeve 51 is installed in place, at this time, the second rod section 112 and the fixed section 32 are locked together. By setting the threaded sleeve 51, the connection stability between the frame 10 and the temple 30 is further enhanced, and the use is more reliable. In addition, when it is needed to separate the frame 10 and the temple 30, first rotate the threaded sleeve 51 to release the connection relationship between the threaded sleeve 51 and the second rod section 112, and then pull out the plug post 31 from the plug slot 101 to realize the separation between the two.

[0032] As a preferred embodiment, the outer peripheral surface of the threaded sleeve 51 is provided with an anti-skid structure, which can increase the friction between the user's fingers and the threaded sleeve 51, and facilitate the user to rotate the threaded sleeve 51 by hand. It can be understood that the anti-skid structure is knurling or protrusion or groove, etc., which is not limited here.

[0033] The end of the folding section 33 away from the fixed section 32 is bent to facilitate hooking on the ear part through the bending part when wearing the reading and writing glasses. The fixed section 32 is fixedly connected with a first ear plate 322, the folding section 33 is fixedly connected with a second ear plate 331, the first ear plate 322 is fixedly connected with a rotating shaft 323, the second ear plate 331 is rotatably connected with the rotating shaft 323, and the folding section 33 can be unfolded and folded by rotating, which is convenient for wearing and storing. When the folding section 33 is in the unfolded state, the end of the folding section 33 abuts against the end of the fixed section 32, thereby limiting the folding section 33.

[0034] The reading and writing mirror easy to assemble has the advantages that the user can insert the inserting column 31 into the inserting groove 101 of the mirror frame 10 to realize preliminary connection, then the thread sleeve 50 is rotated manually to make the thread sleeve 50 threadedly connected with the fixed section 32, the limiting effect of the positioning flange 321 on the thread sleeve 51 is matched, the second rod section 112 on the mirror frame 10 can be finally locked on the fixed section 32 to realize the connection between the mirror frame 10 and the temple 30, other tools are not needed in the assembling process, the dismounting operation is facilitated, the connection stability is stronger, and the use is more reliable.

[0035] The above is the ideal embodiment of the present application, and the above description can be varied and modified without departing from the scope of the present application. The technical scope of the present application is not limited to the content of the specification, and must be determined by the scope of the claims.
