Description

Technical Field

[0001] This utility model relates to optical lenses, and more particularly to an optical lens holder. Background Technology

[0002] Optical lenses with mirror surfaces are widely used due to their advantages such as strong impact resistance, good toughness, and resistance to breakage. The processing flow of optical lenses generally includes steps such as cutting, rough grinding, polishing, cleaning, drying, and coating. After processing, samples need to be placed for display.

[0003] Currently, optical lenses are typically displayed in showcases through transparent glass. While this method is common, it has limitations. Care must be taken when handling them, and the lenses must be spaced appropriately for easy display and subsequent handling, making it inconvenient. Furthermore, the height and viewing angle are difficult to adjust, failing to meet practical needs. To address these inconveniences in displaying optical lenses, existing technology has designed optical lens racks, such as the one described in Chinese patent application CN202420720417.4. This rack includes a base with a support on top. A placement tray is mounted on the support via an adjustable mechanism, and a shelf is mounted on the tray. The top of the placement tray has evenly spaced slots, and the center has a fitting opening. A notch is formed between the slots and the fitting opening. The shelf includes a lens placement base located inside the slots. A fixing rod is fixed to one side of the top of the lens placement base, and a transparent panel is fixed to the top of the fixing rod. Lifting mechanisms for raising the lens placement base are installed on the fitting opening and the notch.

[0004] Existing technologies, such as the aforementioned optical lens holder, place the lens holder within a slot, allowing observation through a transparent panel. A pull ring allows the entire holder to be lifted for easy removal or replacement of optical lenses, and angle and height adjustments are also possible. However, lifting the cylindrical head, connecting rod, lens holder, and lens together via a centrally located pull ring results in an uneven center of gravity. Directly pulling the ring may cause the entire unit to tilt to one side, posing a safety hazard. Furthermore, the angle adjustment function is achieved solely through the U-shaped frame and bolts and nuts. Tightening the bolts and nuts to increase friction between the fixing block and the U-shaped frame for angle fixation carries a risk of loosening. Therefore, an optical lens holder is needed to address the issues of center of gravity shift during lifting and angle adjustment of the placement tray. Summary of the Invention

[0005] To address the issues of center of gravity shift when lifting the shelf and angle adjustment of the placement tray in the prior art, this invention proposes an optical lens shelf, the technical solution of which is as follows.

[0006] An optical lens holder includes a base, a pick-and-place frame disposed on the top surface of the base, and a support disposed on the bottom surface of the base.

[0007] The pick-and-place frame is composed of several coplanar lens placement seats evenly surrounding the base axis, and the lens placement seats are fixed to each other by connectors. The pick-and-place frame is provided with a movable telescopic skeleton and a handle. The movable telescopic skeleton includes several sets of axially telescopic sleeves. Each sleeve includes an outer sleeve and an inner sleeve that are coaxially connected. The two ends of the sleeve are respectively hinged to the handle and the lens placement seat, so that when the handle is pulled up, the sleeve extends axially along its own axis. When the sleeve extends to its limit, the handle is fixed directly above the center of gravity of the pick-and-place frame.

[0008] The top surface of the base is provided with a receiving groove to accommodate the pick-up and put-down frame;

[0009] The base is movably mounted on the support, and the bottom surface of the base is provided with an angle adjustment plate, which allows the base to be adjusted and fixed relative to the support.

[0010] Furthermore, the connecting member is a connecting rod that is coplanar and coaxial with the top surface of the base. The connecting rod is made of rigid material and its two sides are respectively fixedly connected to the adjacent lens placement seats.

[0011] Furthermore, the portion of the inner cylinder inserted into the outer cylinder is provided with a flange protruding outward perpendicular to its own axis, and the inner wall of the outer cylinder is provided with a protrusion protruding inward perpendicular to its own axis. The protrusion can restrict the inner cylinder from coaxially dislodging from the outer cylinder.

[0012] Furthermore, the handle and the connector are respectively provided with a first bearing and a second bearing. The inner sleeve is provided with a first movable connecting ring at the end away from its own flange, and the outer sleeve is provided with a second movable connecting ring at the end away from its own protrusion. The first bearing and the second bearing are both U-shaped plates, and a detachable movable shaft is provided between the plates of the U-shaped plates. The first movable connecting ring and the second movable connecting ring are respectively coaxially sleeved on the movable shafts of the first bearing and the second bearing.

[0013] Furthermore, the support includes a support column and a support leg disposed at the bottom end of the support column. The top end of the support column is movably connected to the center of the bottom surface of the base, so that the base can rotate around the center of its own bottom surface.

[0014] Furthermore, the angle adjustment mechanism includes a pair of parallel angle adjustment discs disposed on the bottom surface of the base. The angle adjustment discs are semi-circular flat plates with the center of the circle containing the outer contour of the angle adjustment disc as the center point. Multiple circular holes perpendicularly penetrating the disc surface are equidistantly opened around the center point along the curvature direction of the outer periphery of the angle adjustment disc. The support column is provided with a fixing through hole. When the fixing through hole and the circular hole are coaxial, bolts can be inserted through the fixing through hole and the circular hole to fix the angle of the base.

[0015] This invention offers the following advantages: Addressing the issue of center-of-gravity shift when lifting the shelf, the lens placement base is evenly distributed at equal angles around the base axis, forming a ring frame with rigid arc-shaped connectors. This concentrates the overall center of gravity on the base axis, preventing tilting risks caused by center-of-gravity shift. The movable telescopic frame, through a sleeve linkage mechanism, automatically adjusts to be directly above the center of gravity of the lifting frame when the handle is pulled up, ensuring the vertical force direction is aligned with the center of gravity and preventing unilateral force imbalance. Furthermore, the internal flange and external protrusion of the sleeve cooperate to limit the telescopic range and maintain axial alignment, ensuring structural rigidity during lifting and further maintaining center-of-gravity stability. Regarding the angle adjustment of the placement tray, the equidistantly distributed circular holes on the semi-circular angle adjustment tray cooperate with the support fixing through holes. Discrete angle fixing is achieved by inserting bolts into different holes, eliminating the risk of loosening and providing precise angle selection compared to friction fixing. A pair of parallel angle adjustment trays are set on the bottom surface of the base, enhancing the torsional rigidity of the adjustment mechanism and ensuring no shaking of the base after angle locking, thus improving the stability of lens placement.

Detailed Implementation

[0025] The present invention will now be described with reference to the accompanying drawings:

[0026] like Figure 1 and Figure 5 As shown, an optical lens holder includes a base 1, a pick-and-place frame disposed on the top surface of the base 1, and a bracket disposed on the bottom surface of the base 1.

[0027] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, the pick-and-place frame is composed of several coplanar lens placement seats 2 evenly surrounding the axis of the base 1, and the lens placement seats 2 are fixed to each other by connectors 3. The pick-and-place frame is provided with a movable telescopic skeleton and a handle 4. The movable telescopic skeleton includes several sets of axially telescopic sleeves. Each sleeve includes an outer sleeve 7 and an inner sleeve 8 that are coaxially connected. The two ends of the sleeve are respectively hinged to the handle 4 and the lens placement seat 2, so that when the handle 4 is pulled up, the sleeve extends axially along its own axis. When the sleeve extends to its limit, the handle 4 is fixed directly above the center of gravity of the pick-and-place frame, ensuring the vertical force direction and eliminating the risk of unilateral force imbalance.

[0028] like Figure 3 As shown, the top surface of the base 1 is provided with a receiving groove 5, in which the receiving groove 5 can hold the pick-and-place frame and allow it to be picked up and placed freely.

[0029] like Figure 5 As shown, the base 1 is movably mounted on the support, and the bottom surface of the base 1 is provided with an angle adjustment plate 6, which enables the base 1 to be adjusted and fixed relative to the support.

[0030] like Figure 1 , Figure 2 As shown, preferably, the connecting member 3 is a connecting rod that is coplanar with the top surface of the base 1. The connecting rod is made of rigid material and its two sides are respectively fixedly connected to the adjacent lens placement seats 2. The rigid connecting rod connects the adjacent lens placement seats 2 to form a stable ring frame structure that resists deformation under external loads.

[0031] like Figure 4 , Figure 6Preferably, the portion of the inner cylinder 8 inserted into the outer cylinder 7 is provided with a flange 9 protruding outward perpendicular to its own axis, and the inner wall of the outer cylinder 7 is provided with a protrusion 10 protruding inward perpendicular to its own axis. The protrusion 10 can restrict the inner cylinder 8 from coaxially disengaging from the outer cylinder 7, preventing structural separation during the lifting process.

[0032] like Figure 4 , Figure 6 , Figure 7 , Figure 8 As shown, preferably, the handle 4 and the connector 3 are respectively provided with a first bearing 11 and a second bearing 12. The inner sleeve is provided with a first movable connecting ring 13 at the end away from its own flange 9, and the outer sleeve is provided with a second movable connecting ring 14 at the end away from its own protrusion 10. The first bearing 11 and the second bearing 12 are both U-shaped plates, and a detachable movable shaft 15 is provided between the plates of the U-shaped plates. The first movable connecting ring 13 and the second movable connecting ring 14 are respectively coaxially sleeved on the movable shaft 15 of the first bearing 11 and the second bearing 12.

[0033] like Figure 5 As shown, preferably, the support includes a support column 17 and a support leg 18 disposed at the bottom end of the support column 17. The top end of the support column 17 is movably connected to the center of the bottom surface of the base 1, so that the base 1 can rotate around its own bottom surface center. The angle adjustment mechanism includes a pair of mutually parallel angle adjustment discs 6 disposed on the bottom surface of the base 1. The angle adjustment disc 6 is a semi-circular plate, with the center of the circle containing the outer contour of the angle adjustment disc 6 as the center point. Around this center point, multiple circular holes 16 are equidistantly opened on the disc surface along the curvature direction of the outer periphery of the angle adjustment disc 6, perpendicularly penetrating the disc surface. The support column 17 is provided with a fixing through hole 19. When the fixing through hole 19 and the circular hole 16 are coaxial, bolts can be inserted through the fixing through hole 19 and the circular hole 16 to fix the angle of the base 1. The base 1 is tilted with the top end of the support column 17 as the rotation point. Combined with the angle adjustment discs 6, multiple fixed positions can be achieved to adapt to different observation angle requirements.

[0034] When using this optical lens holder, the lens must first be placed on the lens placement seat 2, and the base 1 adjusted to be horizontal. Apply vertical upward force through the handle 4 to extend the sleeve of the movable telescopic frame along the axis to its limit position, so that the handle 4 automatically aligns directly above the center of gravity of the pick-up and drop frame, and the entire frame is lifted stably to pick up, drop or replace the lens. Then, place the frame into the receiving groove 5 on the top surface of the base 1. When adjusting the angle, rotate the base 1 to the required tilt angle, and mechanically lock it by inserting bolts into the corresponding round holes 16 on the angle adjustment disc 6 and the fixing through holes 19 on the support column 17 to ensure that the base 1 is stable and does not shift, thereby meeting the needs of optical lens storage, replacement and multi-angle adaptation. It should be noted that when removing the sampling frame from the base 1, the base 1 must be adjusted to a horizontal state.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
