[0035] As known from the background art, the conventional suction pen tool has significant deficiencies in terms of universality and installation efficiency. The soft suction disc is suitable for sucking lenses, but since the suction disc is made of soft material, it is difficult to apply accurate installation force to the lens, resulting in insufficient control precision in the installation process, and often the tool needs to be frequently replaced to adapt to different operation requirements.

[0037] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0038] It should be noted that the indicated orientation or position relationship involved in the present specification is based on the orientation or position relationship shown in the drawings, and is only for the convenience of description and simplification of description, and does not indicate or imply that the device must have a specific orientation and be constructed in a specific orientation, so it cannot be understood as a limitation on the utility model.

[0039] The utility model embodiment provides a kind of lens installation tool, refer to Figure 1 , lens installation tool, comprising: external handle 100, external handle 100 one end is provided with adjusting component 103;Internal handle 200, set in the internal handle 100 of external handle 100 and can along the external handle 100 axial telescopic, the internal handle 200 in with adjusting component 103 same side one end is provided with sealing component 203;When the internal handle 200 stretches out, the interval between the sealing component 203 and the lens in the axial direction is not greater than the interval between the adjusting component 103 and the lens in the axial direction;When the internal handle 200 is retracted, the interval between the sealing component 203 and the lens in the axial direction is not less than the interval between the adjusting component 103 and the lens in the axial direction.

[0040] In the embodiments of the utility model, the lens mounting tool is in work, the inside handle 200 can be telescopic relative to the outside handle 100 along the axial direction, and the end of the inside handle 200 and the outside handle 100 is provided with sealing component 203 and adjusting component 103 respectively. When the inside handle 200 is telescopic relative to the outside handle 100 along the axial direction, the sealing component 203 of the end of the inside handle 200 is close to the lens, and is used to suck the lens. When the inside handle 200 is telescopic relative to the outside handle 100 along the axial direction, the adjusting component 103 of the end of the outside handle 100 is against the lens, and is used to adjust the position of the lens.

[0041] Specifically, when the inside handle 200 is telescopic relative to the outside handle 100, the sealing component 203 is close to the lens, so that the lens is adsorbed on the sealing component 203 and can be moved to the specified position with the lens mounting tool. At this time, in the axial direction, the interval between the sealing component 203 and the lens is not greater than the interval between the adjusting component 103 and the lens. Then, the inside handle 200 is telescopic into the outside handle 100, the lens is separated from the sealing component 203, in the axial direction, the interval between the adjusting component 103 and the lens is less than or equal to the interval between the sealing component 203 and the lens, the adjusting component 103 is against the lens, and the position of the lens is adjusted.

[0042] In some embodiments, referring to Figure 2 And Figure 3 The outside handle 100 can be provided with a through hole 101 along the axial direction. The inner diameter of the through hole 101 is greater than the outer diameter of the inside handle 200. The through hole 101 can be arranged in the outside handle 100 along the axial direction as a sliding channel of the inside handle 200, so that the inside handle 200 can slide along the axial direction.

[0043] In some embodiments, the inside handle 200 can be further provided with an air channel 201 along the axial direction. The air channel 201 penetrates the inside of the inside handle 200, and is provided with a sealing component 203 at one end on the same side as the adjusting component 103. By adjusting the air pressure of the air channel 201, the air channel 201 is switched between normal pressure and negative pressure state, so that the sealing component 203 can suck the lens when the air channel 201 is in negative pressure state.

[0044] In some embodiments, an air pipe 204 can be arranged in the air channel 210, and the other end of the air pipe 204 can be connected with an external negative pressure generator (not shown in the figure) to adjust the air pressure inside the air channel 201. The air pipe 204 and the air channel 201 can adopt a sealing joint or a quick connector, so that the air pipe 204 and the air channel 201 have good air tightness and are convenient to disassemble and assemble.

[0045] In some embodiments, the axial dimension of the inner handle 200 can be larger than that of the outer handle 100, and the end of the air channel 201 of the inner handle 200 is configured to be exposed outside the outer handle 100 so as to be connected to the air tube 204 or an external negative pressure generator. Alternatively, the axial dimension of the inner handle 200 can also be smaller than that of the outer handle 100, so as to make the inner handle more portable and easier to slide in the outer handle, thereby precisely controlling the position of the sealing member, and the outer handle is longer and can provide sufficient space for the sliding of the inner handle.

[0046] In some embodiments, the lens mounting tool can further comprise an outer cover 102 arranged at the end of the outer handle 100.

[0047] The adjusting member 103 can be arranged at the end of the outer cover 102 away from the outer handle 100. For example, the adjusting member 103 can be arranged along the edge of the outer end surface of the outer cover 102, and the outer cover 102 is close to the lens so that the adjusting member 103 can adjust the position and posture of the lens. The adjusting member 103 can be an adjusting ring arranged along the edge of the end of the outer cover 102. In some embodiments, the adjusting member 103 can be detachably arranged on the outer cover 102. By detachably replacing different adjusting members 103, different shapes and sizes of lenses can be adapted, which is beneficial to precisely adjust the position and posture of the lens, and different materials of the adjusting member 103 can also be replaced according to needs to adapt to lenses of different materials.

[0048] In some embodiments, the outer cover 102 can have different structural shapes, for example, the outer cross section of the outer cover 102 can be hemispherical or regular hexagonal, etc. The outer cover 102 provides support for the adjusting member 103, and by arranging the outer cover 102 with different structural shapes, the contact area between the adjusting member 103 and the lens can be expanded, the matching degree of the adjusting member 103 and the lens can be improved, and the accuracy and efficiency of the adjustment can be improved.

[0049] In some embodiments, the outer cover 102 and the outer handle 100 can be integrally formed, thereby being able to provide stable support for the precise adjustment of the lens and being beneficial to guarantee the adjustment accuracy of the lens. In some embodiments, the outer cover 102 and the outer handle 100 can also be detachably connected. For example, a threaded connection or a buckle type connection or a plug-in type connection, etc. can be adopted, and such a connection mode should be able to guarantee the stability during use and facilitate quick disassembly.

[0050] In some embodiments, the lens mounting tool can further comprise an inner cover 202 arranged at the end of the inner handle 200 on the same side as the adjusting member 103. The inner cover 202 is half-enclosed by the outer cover 102, so that the inner handle 200 can be extended and retracted along the axial direction compared with the outer handle 100.

[0051] The sealing member 203 can be arranged at the end of the inner cover 202 away from the inner handle 200. For example, the sealing member 203 can be a sealing ring arranged along the edge of the outer end surface of the inner cover 202. The sealing member 203 can also be a half cover of the inner cover 202, for example, the sealing member 203 is a sealing half cover. When the inner handle 200 is in the extended state, the lens is sucked by closely fitting the sealing member 203 to the lens by moving the inner cover 202 close to the lens. In some embodiments, the sealing member 203 is detachably arranged at the end of the inner cover 202. The end of the sealing member 203 and the inner cover 202 is detachably connected, and different sizes of sealing members 203 can be replaced as needed to adapt to lenses of different sizes, which is beneficial to enhance the versatility of the lens mounting tool.

[0052] In some embodiments, when the inner handle 200 has an air passage 201 for adjusting air pressure, the inner cover 202 can be in communication with the air passage 201. When the sealing member 203 is close to the lens, a negative pressure environment is provided through the air passage 201, so that the sealing member 203 is closely fitted to the lens, and the lens is sucked. Further, a sealing ring or other sealing structure (not shown in the figure) can be arranged at the connection between the inner cover 202 and the inner handle 200 to ensure the sealing of the air passage 201 and prevent air leakage during lens suction.

[0053] In some embodiments, the inner cover 202 and the inner handle 200 can be integrally formed, thereby being able to more firmly adsorb the lens. In some embodiments, the inner cover 202 and the inner handle 200 can also be detachably connected. For example, threaded connection, buckle connection or plug-in connection and the like can be used. Such connection should be able to ensure stability during use and facilitate quick disassembly.

[0054] In some embodiments, the axial dimension of the inner cover 202 is not greater than the axial dimension of the outer cover 102. When the inner cover 202 is extended, the end of the inner cover 202 will not protrude from the end of the outer cover 102. During lens suction, the lens will not be completely exposed outside the outer cover 102, which is beneficial to protect the lens from being damaged.

[0055] In some embodiments, at least one of the adjusting member 103 and the sealing member 203 has an arc surface or a flat surface protruding structure at the interface with the lens, so that at least one of the adjusting member 103 and the sealing member 203 can contact lenses of different shapes (convex, concave, flat) or different sizes, providing a larger applicable range.

[0056] As shown in FIG. 1, the lens mounting tool 100 comprises an outer cover 102, an inner cover 202, an inner handle 200 and a lens 300. Figure 3As shown, the arc-shaped protruding structure has a concave curved surface, and the sealing component 203 and the adjusting component 103 are configured to pick up and adjust the convex lens. The concave curved surface of the arc-shaped protruding structure can form a larger contact area with the convex surface of the convex lens, resulting in a better fit and improved sealing effect during pickup, which is beneficial for stable lens pickup. In addition, the concave curved surface of the arc-shaped protruding structure of the adjusting component 103 also allows the adjusting component 103 to adjust the position and orientation of the convex lens more accurately and effectively.

[0057] like Figure 4 As shown, the arc-shaped protruding structure has an outwardly convex curved surface. The sealing component 203 and the adjusting component 103 are configured to pick up and adjust the concave lens. The arc-shaped protruding structure of the sealing component 203 has an outwardly convex curved surface structure, which can better adapt to the surface shape of the concave lens and form a larger contact area with the concave surface of the concave lens, which is conducive to forming a good seal between the sealing component 203 and the surface of the concave lens. In addition, the arc-shaped protruding structure of the adjusting component 103 has an outwardly convex curved surface structure, which can also enable the adjusting component 103 to better transmit force to the concave lens, making the adjustment of the position and orientation of the concave lens more precise and effective.

[0058] like Figure 5 As shown, at least one of the adjusting component 103 and the sealing component 203 adopts a planar structure. The sealing component 203, using a planar structure as its contact surface, can completely conform to the surface of the plane lens, forming a larger contact area and facilitating a good seal. The adjusting component 103, using a planar structure as its contact surface, makes adjusting the position and orientation of the plane mirror more precise and effective.

[0059] Optionally, the hardness of the adjusting component 103 can be greater than that of the sealing component 203. The lower hardness of the sealing component 203 allows it to fit tightly against the lens surface, forming a seal and enabling lens pickup. The higher hardness of the adjusting component 103 allows it to transmit minute and precise adjustments to the lens, enabling accurate control of the lens's position and orientation, ensuring the accuracy of the lens's posture. Therefore, this lens installation tool not only picks up the lens but also precisely adjusts its position and orientation, possessing good versatility and improving lens installation efficiency and accuracy.

[0060] In some embodiments, the lens mounting tool may further include a position adjustment structure 300 configured to adjust the relative position of the inner handle 200 and the outer handle 100.

[0061] The position adjusting structure 300 controls the relative position between the sealing member 203 and the adjusting member 103 by adjusting the relative position of the inner handle 200 and the outer handle 100. For example, in the lens suction stage, the position adjusting structure 300 allows the inner handle 200 to extend from the outer handle 100, so that the sealing member 203 is in close contact with the lens surface, and an effective seal is formed between the sealing member 203 and the lens. For another example, the position adjusting structure 300 allows the inner handle 200 to be fixed relative to the outer handle 100, so that the relative displacement of the two is avoided, and the stability of the suction is ensured, so as to facilitate the installation of the lens to the to-be-installed position. Therefore, the position adjusting structure 300 allows the lens installation tool to quickly switch between the suction and the installation functions, and improves the work efficiency.

[0062] In some embodiments, the position adjusting structure 300 further comprises: a movable part 301 adapted to adjust the position adjusting structure 300, so that the inner handle 200 is axially telescoped along the outer handle 100; and a locking part 302 adapted to limit the movement of the movable part 301 when the movable part 301 reaches a set position, so that the inner handle 200 and the outer handle 100 are relatively fixed.

[0063] In some embodiments, the movable part 301 and the locking part 302 are movably connected.

[0064] In some embodiments, the side wall of the outer handle 100 can be provided with a sliding groove 104 extending in the axial direction. The sliding groove 104 can have a certain axial extension length, which can smoothly allow the sealing ring to suck the lens, and also avoid the inner handle 200 from falling off the outer handle 100.

[0065] The movable part 301 is connected with the inner handle 200. Specifically, the movable part 301 can at least partially penetrate the sliding groove 104 and be connected with the inner handle 200, so that the relative movement of the movable part 301 along the sliding groove 104 drives the inner handle 200 to telescope in the outer handle 100.

[0066] In some embodiments, the locking portion 302 is arranged at one end of the movable portion 301. During the lens suction process, the locking portion 302 is away from the outer handle 100, and the inner handle 200 can freely slide in the outer handle 100. The position of the inner handle 200 is adjusted so that the sealing component 203 can be close to the lens and achieve sealing contact with the lens surface to suck the lens. During the lens taking process, the locking portion 302 is close to the outer handle 100, and the outer handle 100 is abutted on the inner handle 200, so that the outer handle 100 and the inner handle 200 are fixed together. During the lens debugging process, the locking portion 302 is loosened, and the outer handle 100 and the inner handle 200 are separated. The position of the inner handle 200 is adjusted so that the adjusting component 103 of the outer cover 102 on the outer handle 100 can adjust the position and attitude of the lens.

[0067] In some embodiments, the locking portion 302 is a limiting structure arranged on the side wall or end portion of the outer handle 100.

[0068] In some embodiments, the movable portion 301 is a pin shaft passing through the sliding groove 104, and a limiting structure is arranged at the end of the pin shaft away from the inner handle 200.

[0069] In some embodiments, the inner side wall of the locking portion 302 is provided with a threaded hole, and the outer side wall of the movable portion 301 is provided with an external thread. The movable portion 301 and the locking portion 302 are threadedly connected, the position of the locking portion 302 relative to the inner handle 200 is adjusted, and the fixing or separation between the inner handle 200 and the outer handle 100 is controlled. Specifically, the size of the locking portion 302 can be greater than the width of the sliding groove 104, so that when the locking portion 302 is close to the outer handle 100, the inner handle 200 and the outer handle 100 are abutted together, and the inner handle 200 and the outer handle 100 can be effectively fixed.

[0070] In some embodiments, as shown in Figure 6 The locking portion 302a includes a plurality of first limiting holes 303a arranged in the axial direction on the edge of the sliding groove 104a, and a second limiting hole (not marked in the figure) arranged on the movable portion 301a, and the extension direction of the second limiting hole is perpendicular to the axial direction. The locking portion 302a further includes a limiting component for penetrating the first limiting hole 303a and the second limiting hole. For example, a positioning pin is used as the limiting component.

[0071] When the lens mounting tool needs to fix the inner handle 200a and the outer handle 100a, the locking part 302a penetrates the first limiting hole 303a and the second limiting hole simultaneously; when the inner handle 200a needs to be moved relative to the outer handle 100a, the locking part 302a is removed from the first limiting hole 303a, so that the inner handle 200a can be moved relative to the outer handle 100a.

[0072] In other embodiments, as another example, as shown in FIG. 4, a plurality of positioning grooves 303b are arranged on the edge of the sliding groove 104b of the outer handle 100b in the axial direction. Figure 7 The movable part 301b penetrates the sliding groove 104b and is fixedly arranged on the inner handle 200b, the movable part 301b is provided with a first limiting hole (not shown in the figure), and the extending direction of the first limiting hole is parallel to the axial direction; the locking part 302b includes a first part and a second part which are perpendicular to each other, the first part is rotatably arranged in the first limiting hole, and the second part is used for clamping in the positioning groove 303b.

[0073] When the lens mounting tool needs to fix the inner handle 200b and the outer handle 100b, the locking part 302b is rotated, and the second part of the locking part 302b is clamped in the positioning groove 303b; when the inner handle 200b needs to be moved relative to the outer handle 100b, the locking part 302b is rotated, and the second part of the locking part 302b is removed from the positioning groove 303b, so that the inner handle 200b can be moved relative to the outer handle 100b.

[0074] Therefore, the lens mounting tool can not only realize the suction of the lens, but also accurately adjust the position and posture of the lens, has good universality, and improves the installation efficiency and installation accuracy of the lens.

[0075] Although the embodiments of the utility model are disclosed as above, the utility model is not limited to this. Any person skilled in the art can make various changes and modifications without departing from the spirit and scope of the utility model, therefore the protection scope of the utility model should be limited by the range defined by the claims.
