Description

Technical Field

[0001] This utility model relates to the field of plane mirror imaging experimental technology, specifically a multi-legged plane mirror. Background Technology

[0002] There is an experiment in the junior high school physics textbook called "Studying the Characteristics of Plane Mirror Imaging". The experiment requires a transparent plane mirror that can stand upright. The plane mirrors currently in use are made of traditional glass, which has too many disadvantages, such as being easily broken, sharp to the touch, and forming two virtual images due to their thickness. Furthermore, during the experiment, multi-legged plane mirrors have poor stability and are prone to tipping over or shifting when subjected to external forces, making it difficult to position the plane mirror and affecting the experimental results. Therefore, the inventor of this invention has designed a multi-legged plane mirror to overcome the many drawbacks of traditional plane mirrors, reduce experimental errors, and meet the requirements of standard experiments. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a multi-legged plane mirror that solves the problems of being easily broken, easily hurting the hand, and forming two virtual images when too thick. It also has good stability and is easy to position the plane mirror to reduce experimental errors.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A multi-legged plane mirror includes a plane mirror and a support frame installed at the bottom of the plane mirror. The support frame includes two parallel side supports with an inverted V-shaped structure. A positioning plate is vertically fixed to one side of each of the two side supports. The plane mirror is installed between the two positioning plates. A positioning and mounting structure is provided between the plane mirror and the positioning plates. A connecting frame is also fixedly connected between the bottoms of the two side supports. The connecting frame is located on the non-reflective side of the plane mirror. The bottoms of the two legs of the support frame are provided with anti-slip structures.

[0006] Preferably, the plane mirror is an acrylic sheet.

[0007] Preferably, the positioning and mounting structure includes a positioning groove opened along the length of one side of the positioning plate, an embedding groove communicating with the positioning groove is opened on the top of the positioning plate, the depth of the embedding groove is greater than the depth of the positioning groove, and positioning notches are opened at the lower ends of both sides of the plane mirror. When the plane mirror is installed between the two positioning plates, the positioning notches are placed in the positioning groove, and the plane mirror part is placed in the embedding groove.

[0008] Preferably, the positioning plate has a through mounting hole at the embedded groove, and the plane mirror has a through hole corresponding to the mounting hole. The plane mirror and the positioning plate are connected and fixed by fixing bolts passing through the mounting hole and the through hole.

[0009] Preferably, the anti-slip structure includes grooves formed at the bottom of the two legs of the side bracket and foot pads installed in the grooves, the foot pads protruding from the lower surface of the support frame.

[0010] Preferably, a groove is formed on the inner wall of the groove, and an insert strip is provided on the outer wall of the foot pad, the insert strip being aligned and inserted into the groove.

[0011] Preferably, the bottom of the two legs of the side bracket is provided with a buckle groove on one side of the groove.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention utilizes an acrylic sheet for the plane mirror, making it extremely thin. This allows the two virtual images formed after two reflections of an object to almost completely overlap, resulting in a clear imaging effect. The material used is sturdy, unbreakable, and non-sharp, enhancing safety. A side bracket is installed on the side of the plane mirror, and a connecting frame is placed on the non-reflective surface. This allows students to draw a straight line along the bottom edge of the plane mirror's reflective surface on paper, from one side of the mirror to the other, and to set this line as the position of the plane mirror, ensuring accurate positioning of the plane mirror during imaging experiments.

[0021] 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. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0022] Example: Please refer to Figures 1-6 This embodiment provides a multi-legged plane mirror, including a plane mirror 1 and a support frame 2 installed at the bottom of the plane mirror 1. The plane mirror 1 is made of acrylic sheet, and the material of the plane mirror 1 can also be PC, etc., as long as it achieves a thin and transparent effect, making the plane mirror 1 very thin, so that the two virtual images formed after the object is reflected twice by the plane mirror 1 almost completely overlap, resulting in a clear imaging effect. The material used is strong, unbreakable, and does not hurt the hands, thus improving safety.

[0023] In this embodiment, as Figure 2 As shown, the support frame 2 includes two parallel side supports 21, which are inverted V-shaped structures. Positioning plates 22 are vertically fixed to opposite sides of each side support 21. The plane mirror 1 is installed between the two positioning plates 22. A positioning and mounting structure is provided between the plane mirror 1 and the positioning plates 22. A connecting frame 23 is also fixedly connected between the bottoms of the two side supports 21, located on the non-reflective side of the plane mirror 1. Anti-slip structures are provided at the bottoms of the legs on both sides of the support frame 2. The two side supports 21 are connected as one unit via the connecting frame 23. The plane mirror 1 is installed between the two positioning plates 22. When the plane mirror 1 is installed in place, the bottom end of the plane mirror 1 is basically flush with the bottom end of the side supports 21. The inverted V-shaped side support 21 provides multi-leg support for the plane mirror 1, improving stability. The connecting frame 23 has a U-shaped structure and is equipped with a protruding stop. It is positioned on the side of the plane mirror 1 through the side support 21, without obstructing the reflecting surface of the plane mirror 1. This allows the pen to draw a straight line on the paper along the bottom edge of the plane mirror 1 from one side to the other. The obstruction of the connecting frame 23 on the bottom of the other side of the plane mirror forces students not to draw a straight line along the edge of the plane mirror 1 on the paper at the bottom of this side, but only along the bottom edge of the reflecting surface of the plane mirror. This straight line is then used as the position of the plane mirror 1, ensuring accurate positioning of the plane mirror during the plane mirror imaging experiment.

[0024] In this embodiment, as Figure 3 and Figure 4As shown, the positioning and mounting structure includes a positioning groove 221 formed along the length of one side of the positioning plate 22. An embedding groove 222 communicating with the positioning groove 221 is formed on the top of the positioning plate 22. The depth of the embedding groove 222 is greater than the depth of the positioning groove 221. Positioning notches 11 are formed at the lower ends of both sides of the plane mirror 1. When the plane mirror 1 is installed between the two positioning plates 22, the positioning notches 11 are placed within the positioning groove 221, and part of the plane mirror 1 is placed within the embedding groove 222. A mounting hole is formed on the positioning plate 22 at the location of the embedding groove 222, and a through hole 12 corresponding to the position of the mounting hole is formed on the plane mirror 1. A fixing bolt 223 passes through the mounting hole and the positioning plate 22 to connect the plane mirror 1. The through hole 12 is used for connection and fixation. When installing the plane mirror 1 and the support frame 2, the lower end of the plane mirror 1 is inserted into the positioning grooves 221 of the two support frames 2. When the plane mirror 1 is installed in place, the positioning notch 11 of the plane mirror 1 is placed in the positioning groove 221, and then the part of the plane mirror 1 above the positioning notch 11 is placed in the embedding groove 222 to form a locking position, which limits the position of the plane mirror 1. Then, the plane mirror 1 and the support frame 2 are connected and fixed by the fixing bolt 223, which facilitates the installation of the plane mirror 1, ensures the consistency of the installation position of the plane mirror 1, and makes the plane mirror 1 and the support frame 2 detachable. If the plane mirror 1 is damaged, it can be replaced, and the support frame 2 can be reused to reduce costs.

[0025] In this embodiment, as Figure 5 As shown, the anti-slip structure includes grooves 211 formed at the bottom of the two legs of the side bracket 21 and foot pads 3 installed in the grooves 211. The foot pads 3 protrude from the lower surface of the support frame 2. The foot pads 3 can be made of rubber. By installing foot pads 3 at the bottom of the legs of the side bracket 21, the friction with the table and paper is increased, the stability of the multi-legged plane mirror is enhanced, and the position of the multi-legged plane mirror is prevented from shifting during the experiment.

[0026] In this embodiment, as Figure 5 and Figure 6 As shown, a groove 212 is formed on the inner wall of the groove 211, and an insert strip 31 is provided on the outer wall of the foot pad 3. The insert strip 31 is integrally formed with the foot pad 3 and is aligned and inserted into the groove 212. The bottom of the two legs of the side bracket 21 and located on one side of the groove 211 are provided with a snap-fit ​​groove. When the foot pad 3 is installed in the groove 211, the insert strip 31 on the foot pad 3 is inserted into the groove 212 to fix the foot pad 3 in the position in the groove 211. The snap-fit ​​groove design makes it easy to remove and replace the worn foot pad 3. The structure is simple and easy to use.

[0027] Working principle: During assembly of the multi-legged plane mirror, the lower end of the plane mirror 1 is inserted into the positioning grooves 221 of the two support frames 2. When the plane mirror 1 is installed in place, the positioning notch 11 of the plane mirror 1 is placed in the positioning groove 221, and then the part of the plane mirror 1 above the positioning notch 11 is placed in the embedding groove 222, forming a locking position and defining the position of the plane mirror 1. Then, the plane mirror 1 is connected and fixed to the support frame 2 by the fixing bolt 223 passing through the mounting hole and the through hole 12, which facilitates the assembly of the plane mirror 1 and the support frame 2. When in use, the multi-legged plane mirror is placed on a piece of paper on a table. The friction is increased by the foot pads 3 at the bottom of the side bracket 21, and the inverted V-shaped side... The bracket 21 provides multi-leg support for the plane mirror 1, improving stability. The side bracket 21 is set on the side of the plane mirror 1, and the connecting bracket 23 is set on the non-reflective surface of the plane mirror 1. This allows students to draw a straight line on paper along the bottom edge of the reflective surface of the plane mirror 1 from one side of the plane mirror 1 to the other side, and set this line as the position of the plane mirror 1. This ensures accurate positioning of the plane mirror during the plane mirror imaging experiment. The plane mirror 1 is made of acrylic sheet, making it very thin. This allows the two virtual images formed after the object is reflected twice by the plane mirror 1 to almost completely overlap, resulting in a clear imaging effect. The material used is sturdy, unbreakable, and does not hurt the hands, improving safety.

[0028] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
