Description

Technical Field

[0001] The invention relates to an angle-adjustable spectacle frame, belonging to the field of optical spectacle frames. Background Art

[0002] In optical products such as laser systems or optical microscopes, the excitation of special light or the observation of specific samples mainly rely on the refraction or reflection of light by internal lenses, where the lenses are mounted on the main body of the equipment through a frame. The lens generally needs to be adjusted in angle in the equipment, and in order to achieve the adjustment of the lens, an adjustment structure for adjusting the lens is usually set on the frame.

[0003] For example, the Chinese utility model patent with the authorization announcement date of November 29, 2019 and the authorization announcement number of CN209707781U discloses an optical frame that is easy to adjust, wherein the optical frame includes a frame support plate (i.e., a component mounting frame) for mounting lenses, and after the lenses are mounted, the lens surface is arranged vertically with the frame support plate. The two sides of the end of the frame support plate are mounted on the support ears of the middle support seat through steel nails (i.e., the rotation axis), so that the frame support plate can rotate relative to the support ears. A tension spring is also arranged between the middle support seat and the frame support plate. The tension spring makes the frame support plate tend to rotate toward the middle support seat. In order to stabilize the frame support plate at a specific position, a hand-adjustable thread pair (i.e., a top screw) is also arranged on the middle support seat. The top screw thread is assembled on the middle support seat. One end of the top screw abuts against the frame support plate, and the other end is provided with a knob for operation. The top screw generates a thrust on the frame support plate, and the tension spring generates a pulling force on the frame support plate. The frame support plate is maintained at a specific position through the combined action of the tension spring and the top screw.

[0004] However, in the above technical solution, the maintenance of the position of the frame support plate relies on the combined force of the top screw and the tension spring. During the use of the optical frame, the temperature of the frame will increase due to the scattering of light or the continuous use of other heat sources on the equipment, and the heat will be transferred to the top screw accordingly. Due to the influence of thermal expansion and contraction, the top screw will expand, and then the length of the top screw will change, resulting in a change in the position of the frame support plate. The position of each optical element in the optical product will affect the effects of light beam gathering, refraction and reflection in the optical product. When the position of the frame support plate changes, it will affect the position of the lens, which will correspondingly change the light beam in the optical product, thereby making the stability of the optical product worse. Summary of the invention

DETAILED DESCRIPTION

[0019] The features and performance of the present invention are further described in detail below in conjunction with the embodiments.

[0020] In the present invention, the component mounting frame is rotatably mounted on the support seat, so that the component mounting frame and the support seat are interference fitted, thereby conveniently utilizing the extrusion between the component mounting frame and the support seat to maintain the relative position relationship between the component mounting frame and the support seat.

[0021] In the embodiment 1 of the eyeglass frame with adjustable angle (hereinafter referred to as eyeglass frame) of the present invention: like Figure 1 and Figure 2As shown, in this embodiment, the frame includes a support seat and a component mounting frame 1 for mounting an optical element rotatably assembled in the support seat. The optical element in this embodiment is a lens 7. The lens 7 is described below as an example. Of course, in other embodiments, the optical element can also be other optical elements such as a reflector or a refractor. The support seat forms a mounting base for mounting the component mounting frame 1. In order to achieve the adjustment of the lens 7, the position of the component mounting frame 1 relative to the support seat is adjustable. Specifically, a rotating shaft 13 is provided at both ends of the component mounting frame 1, and a mounting hole for mounting the rotating shaft 13 on the component mounting frame 1 is provided on the support seat. The rotating shaft 13 is interference-fitted in the mounting hole. When the component mounting frame 1 is installed on the support seat, a large extrusion is generated between the support seat and the component mounting frame 1. At this time, a force that inhibits the rotation of the rotating shaft 13 is generated. The position of the component mounting frame 1 relative to the support seat can be maintained by relying on the interference fit between the support seat and the component mounting frame 1.

[0022] like Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, in order to achieve the interference fit between the component mounting frame 1 and the support seat, the support seat includes a support seat body 2 and a fixing member that are separately arranged, and a mounting hole is formed between the support seat body 2 and the fixing member. Specifically, a receiving groove 22 for accommodating the rotating shaft 13 is arranged on the support seat body 2, and the receiving groove 22 is an open structure, which is convenient for the rotating shaft 13 to be directly placed in the receiving groove 22. The fixing member is a fixed plate 3 fixedly arranged at the opening of the receiving groove 22, and the plate surface of the fixed plate 3 and the receiving groove 22 together constitute the mounting hole. Of course, in other embodiments, the upper surface of the support seat body can also be set as a plane, and the receiving groove is set on the fixing member, so as to facilitate the formation of the mounting hole between the support seat body and the fixing member. Alternatively, in other embodiments, receiving grooves that can be assembled with each other can also be formed on the support seat body and the fixing member respectively. Alternatively, in other embodiments, the support seat is separately arranged, and each support seat is provided with a complete mounting hole, and the two parts of the support seat can be connected together after the assembly of the rotating shaft and the mounting hole is completed.

[0023] In order to better produce extrusion between the support seat and the component mounting frame 1, it is necessary to produce a slight deformation when in contact, so the support seat body 2 is peek plastic, which has the characteristics of high temperature resistance, wear resistance, chemical corrosion resistance, self-lubrication, etc., and its deformation is small under high temperature conditions, and its thermal deformation temperature is 315°C, which is convenient for use in this use environment. When the rotating shaft 13 and the support seat body 2 are squeezed against each other, the peek plastic on the support seat body 2 is used to produce a slight deformation, and because the peek plastic has a certain self-lubricating property, it is also convenient for the rotation of the rotating shaft 13 relative to the support seat. In order to install firmly, the fixing plate 3 is a metal plate, and the plate surface of the metal plate is used to assemble with the receiving groove 22. In order to allow the rotating shaft 13 to be interference-fitted in the mounting hole, the diameter of the columnar object that can be accommodated by the receiving groove 22 is slightly smaller than the diameter of the rotating shaft 13, so that the receiving groove 22 can be squeezed and contacted with the rotating shaft 13 after matching with the cover plate. In addition, in order to better squeeze the two, the bottom of the receiving groove 22 is set to be V-shaped. Of course, in other embodiments, the bottom of the receiving groove may be set to an arc shape. Alternatively, in other embodiments, the support seat body is made of plastic materials such as nylon or polyethylene, or may also be made of other materials with a thermal deformation temperature above 300°C, such as polyphenylene imidazole and polyimide. Alternatively, in other embodiments, the support seat body may be set in a split manner, wherein the support seat body includes a metal part and a plastic part, and the plastic part is used to form the mounting hole.

[0024] In order to complete the installation of the lens 7, the component mounting frame 1 includes a first mounting frame 11 and a second mounting frame 12 which are assembled with each other, and the lens 7 is used to be clamped between the first mounting frame 11 and the second mounting frame 12. The first mounting frame 11 and the second mounting frame 12 are fixedly connected by bolts, wherein the first mounting frame 11 is provided with a bolt through hole, and the second mounting frame 12 is provided with a threaded hole for threaded assembly with the bolt. The rotating shaft 13 is arranged on both sides of the first mounting frame 11, and then after the installation is completed, the entire component mounting frame 1 rotates synchronously together with the lens 7 clamped in the middle. In order to achieve the clamping of the lens 7, a component mounting groove for accommodating the lens 7 is arranged on the first mounting frame 11 and runs through the side of the first mounting frame 11, and a lens 7 abutment block is arranged on the second mounting frame 12 for extending into the component mounting groove and abutting with the lens 7 to fix the lens 7 in the component mounting groove. The lens 7 abutment block is stepped, which is convenient for mounting the lens 7 on the stepped surface and the bottom of the component mounting groove in the first mounting frame 11. Of course, in other embodiments, the structures on the first mounting frame 11 and the second mounting frame 12 may also be exchanged, as long as it is ensured that the lens 7 can still be clamped after the assembly is completed.

[0025] In order to adjust the position of the lens 7, an adjustment structure for adjusting the lens 7 is also provided. Specifically, a first adjustment structure is provided on the component mounting frame 1, and a second adjustment structure is provided on the support seat. The first adjustment structure is a vertically arranged insertion hole 14. When a screwdriver, a hexagonal wrench or other rod-shaped tool is inserted into the insertion hole 14, the tool can act as a wrench for adjustment. Of course, the adjustment at this time can only be controlled by the operator, and the control accuracy is poor, which can be used as an initial angle adjustment. Alternatively, in other embodiments, the insertion hole may no longer be provided, and pliers may be used to clamp the outer surface of the component mounting frame for manual adjustment.

[0026] Specifically, a second adjustment structure is also provided on the support seat body 2. The second adjustment structure includes a threaded hole fixedly provided on the support seat and an adjusting screw for being assembled in the threaded hole. A fine-pitch nut mounting hole 23 is provided on the support seat body 2, and a fine-pitch nut 24 is bonded in the fine-pitch nut mounting hole 23, and the fine-pitch nut 24 has a threaded hole. A fine-pitch screw 25 is assembled in the threaded hole, and an inner hexagon operating hole is provided at the end of the fine-pitch screw 25, which is convenient for adjustment using a hexagonal wrench. When it is needed, the inner hexagon operating hole on the fine-pitch screw 25 is screwed with a hexagonal wrench, so that the end of the fine-pitch screw 25 away from the inner hexagon operating hole is conveniently abutted on the component mounting frame 1, so as to facilitate the adjustment of the component mounting frame 1. Since the fine-pitch screw 25 can only be adjusted by pushing, the second adjustment structure includes two opposite sides of the support seat body 2 and located on the component mounting frame 1, and when the angle adjustment is required, one end is pushed to adjust. After the adjustment is completed, the fine-pitch screw 25 is screwed in the reverse direction to facilitate the separation of the fine-pitch screw 25 and the component mounting frame 1, so as to prevent the thermal expansion and contraction of the fine-pitch screw 25 from affecting its accuracy. Of course, in other embodiments, a fine-pitch nut may no longer be provided, but a threaded hole matching the fine-pitch screw may be directly provided on the support seat body, or, in other embodiments, the fine-pitch nut mounting hole may be provided on the fixing plate. Alternatively, in other embodiments, a fine-pitch screw may be assembled in the threaded hole of the fine-pitch nut, and the threaded section of the fine-pitch screw constitutes the fine-pitch screw. When screwing is required, the screw head of the fine-pitch screw may be screwed.

[0027] In order to further reduce the influence of thermal expansion and contraction on the frame, an electronic temperature controller 6 is also provided on the component mounting frame 1. Two electronic temperature controllers 6 are provided, which are respectively installed on the first mounting frame 11 and the second mounting frame 12, so as to realize the temperature control of the first mounting frame 11 and the second mounting frame 12. Of course, in other embodiments, the electronic temperature controller 6 may not be provided. In addition, an aperture mounting hole 21 for installing the aperture 4 is also provided on the support seat body 2. The aperture 4 is installed in the aperture mounting hole 21, and the outer periphery of the aperture 4 is tightened by using the first top screw 51 assembled on the support seat body 2.

[0028] In Embodiment 2 of the angle-adjustable eyeglass frame (hereinafter referred to as eyeglass frame) of the present invention: like Figure 6 and Figure 7 As shown, in this embodiment, the frame includes a support seat and a component mounting frame 1 for mounting an optical element rotatably assembled in the support seat. The optical element in this embodiment is a lens 7. The lens 7 is described below as an example. Of course, in other embodiments, the optical element may also be other optical elements such as a reflector or a refractor. The support seat forms a basis for mounting the component mounting frame 1. In order to adjust the lens 7, the position of the component mounting frame 1 relative to the support seat is adjustable. Specifically, a rotating shaft 13 is provided at both ends of the component mounting frame 1, and a mounting hole for mounting the rotating shaft 13 on the component mounting frame 1 is provided on the support seat. The rotating shaft 13 is interference-fitted in the mounting hole. When the component mounting frame 1 is mounted on the support seat, a large extrusion is generated between the support seat and the component mounting frame 1. At this time, a force that inhibits the rotation of the rotating shaft 13 is generated. The position of the component mounting frame 1 relative to the support seat can be maintained by relying on the interference fit between the support seat and the component mounting frame 1.

[0029] like Figure 7 , Figure 8 , Fig. 9 and Fig.10 As shown, in order to achieve the interference fit between the component mounting frame 1 and the support seat, the support seat includes a support seat body 2 and a fixing member that are separately arranged, and a mounting hole is formed between the support seat body 2 and the fixing member. Specifically, a receiving groove 22 for accommodating the rotating shaft 13 is arranged on the support seat body 2, and the receiving groove 22 is an open structure, which is convenient for the rotating shaft 13 to be directly placed in the receiving groove 22. The fixing member is a fixed plate 3 fixedly arranged at the opening of the receiving groove 22, and the plate surface of the fixed plate 3 and the receiving groove 22 together constitute the mounting hole. Of course, in other embodiments, the upper surface of the support seat body can also be set as a plane, and the receiving groove is set on the fixing member, so as to facilitate the formation of the mounting hole between the support seat body and the fixing member. Alternatively, in other embodiments, receiving grooves that can be assembled with each other can also be formed on the support seat body and the fixing member respectively. Alternatively, in other embodiments, the support seat is separately arranged, and each support seat is provided with a complete mounting hole, and the two parts of the support seat can be connected together after the assembly of the rotating shaft and the mounting hole is completed.

[0030] In order to better produce extrusion between the support seat and the component mounting frame 1, it is necessary to produce a slight deformation when in contact, so the support seat body 2 is peek plastic, which has the characteristics of high temperature resistance, wear resistance, chemical corrosion resistance, self-lubrication, etc., and its deformation is small under high temperature conditions, and its thermal deformation temperature is 315°C, which is convenient for use in this use environment. When the rotating shaft 13 and the support seat body 2 are squeezed against each other, the peek plastic on the support seat body 2 is used to produce a slight deformation, and because the peek plastic has a certain self-lubricating property, it is also convenient for the rotation of the rotating shaft 13 relative to the support seat. In order to install firmly, the fixing plate 3 is a metal plate, and the plate surface of the metal plate is used to assemble with the receiving groove 22. In order to allow the rotating shaft 13 to be interference-fitted in the mounting hole, the diameter of the columnar object that can be accommodated by the receiving groove 22 is slightly smaller than the diameter of the rotating shaft 13, so that the receiving groove 22 can be squeezed and contacted with the rotating shaft 13 after matching with the cover plate. In addition, in order to better squeeze the two, the bottom of the receiving groove 22 is set to be V-shaped. Of course, in other embodiments, the bottom of the receiving groove may be set to an arc shape. Alternatively, in other embodiments, the support seat body is made of plastic materials such as nylon or polyethylene, or may also be made of other materials with a thermal deformation temperature above 300°C, such as polyphenylene imidazole and polyimide. Alternatively, in other embodiments, the support seat body may be set in a split manner, wherein the support seat body includes a metal part and a plastic part, and the plastic part is used to form the mounting hole.

[0031] In order to facilitate the installation of the lens 7, the component mounting frame 1 is an integrated frame, and a component mounting hole for mounting the lens 7 is provided on the component mounting frame 1. The component mounting hole is a round hole, and the part of the component mounting frame 1 used to surround the component mounting hole constitutes the side wall of the mounting hole. The side wall of the mounting hole is also provided with a second top screw 52 that penetrates the side wall of the component mounting frame 1 and abuts against the lens 7. The installation of the lens 7 is facilitated by tightening the second top screw 52. Of course, in other embodiments, the component mounting hole can also be set to be slightly smaller than the lens, so that the lens is interference-fitted in the component mounting hole after installation.
