Description

Technical Field

[0001] This utility model relates to the field of optical lens clamping technology, and in particular to a portable optical lens quick clamping fixture. Background Technology

[0002] In the field of modern optics, optical lenses are widely used in many high-precision industries such as photography, medical care, and scientific research. During their processing and testing, the clamping operation of the lenses is crucial. Reliable clamping can prevent lens damage and ensure the accuracy and quality of processing and testing.

[0003] Currently, when inspecting optical lenses, the general method is to directly handle them by hand, pinching the side of the lens with your fingers. However, fingerprints may stick to the lens during this process. In addition, it requires prolonged pinching, which is tiring and can easily cause the lens to fall and get damaged. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a portable optical lens quick clamp that can overcome or at least partially solve the above problems.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A portable optical lens quick-clamping fixture includes: a fixing ring, and further includes: a fixing tube fixedly disposed on one side of the fixing ring; a connecting rod fixedly disposed at one end of the fixing tube; a handle fixedly disposed at the end of the connecting rod; multiple positioning plates circumferentially and equidistantly disposed on the inner side of the fixing ring, and a guide angle is provided on the lower side of the positioning plates; a limiting plate fixedly disposed on the positioning plates; a pressing rod slidably disposed within the fixing tube, and a pressing head is provided at the end of the pressing rod, the pressing head being used to press and limit the optical lens; and a control component for controlling the movement of the pressing rod, disposed on the handle.

[0007] Preferably, the control component includes a spring fixedly connected between the extrusion rod and the fixed tube, a pull rope fixedly connected to one end of the extrusion rod, a through groove provided on the handle, a control block slidably disposed on the through groove, and the control block fixedly connected to the other end of the pull rope.

[0008] To facilitate the protection of the optical lens, a first protective pad is provided on the extrusion head, and a second protective pad is provided on the limiting plate.

[0009] To facilitate clamping different optical lenses, a threaded rod is rotatably provided on the positioning plate, and the threaded rod is threadedly connected to the fixing ring. A rotating head is fixedly connected to one end of the threaded rod, and a sliding rod is fixedly connected to the positioning plate. The sliding rod is slidably disposed on the fixing ring.

[0010] To facilitate precise adjustment of the positioning plate, the slide bar is further provided with multiple equidistant scale lines.

[0011] Preferably, the connecting rod is a flexible metal hose.

[0012] Compared with the prior art, this utility model provides a portable optical lens quick-grip fixture, which has the following advantages:

[0013] 1. This portable optical lens quick-grip fixture allows the operator to hold the handle and pull the control block, which slides within the through groove. A pull rope then drives the extrusion rod to slide within the fixed tube, causing the extrusion head to move away from the optical lens. The side of the fixing ring where the optical lens is placed faces down. A guide angle positions the lens between multiple positioning plates, and a limiting plate further restricts its position. Releasing the control block causes the extrusion rod to reset under spring pressure, and the extrusion head clamps and secures the optical lens. This allows the operator to transfer or inspect the lens, effectively improving the gripping effect and preventing fingerprints from adhering to the lens when handled directly.

[0014] 2. This portable optical lens quick clamping fixture can protect the sides of the optical lens through the first and second protective pads to prevent damage to the optical lens.

[0015] 3. This portable optical lens quick clamping fixture adjusts the position of the positioning plate by rotating the rotating head and threaded rod. At the same time, the scale lines on the slide rod facilitate precise adjustment of the positioning plate position, thus enabling the clamping of optical lenses of different sizes and making it more versatile.

[0016] The parts not described in this device are the same as or can be implemented using existing technology. This utility model effectively improves the clamping effect of optical lenses, avoids fingerprints sticking to the optical lenses when the hands directly handle them, and can clamp optical lenses of different sizes, making it more applicable.

Detailed Implementation

[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.

[0022] Example 1: Refer to Figures 1-3 A portable optical lens quick-clamping fixture includes: a fixing ring 1, and further includes: a fixing tube 101, fixedly disposed on one side of the fixing ring 1; a connecting rod 102, fixedly disposed at one end of the fixing tube 101; a handle 103, fixedly disposed at the end of the connecting rod 102; multiple positioning plates 2, circumferentially and equidistantly disposed on the inner side of the fixing ring 1, and a guide angle 203 is provided on the lower side of the positioning plates 2; a limiting plate 201, fixedly disposed on the positioning plate 2; a pressing rod 104, slidably disposed inside the fixing tube 101, and a pressing head 105 is provided at the end of the pressing rod 104, the pressing head 105 being used to press and limit the optical lens; and a control component for controlling the movement of the pressing rod 104, disposed on the handle 103.

[0023] The control assembly includes a spring 107 fixedly connected between the extrusion rod 104 and the fixed tube 101. One end of the extrusion rod 104 is fixedly connected to a pull rope 108. A through groove 109 is provided on the handle 103. A control block 110 is slidably arranged on the through groove 109. The control block 110 is fixedly connected to the other end of the pull rope 108.

[0024] When it is necessary to clamp the optical lens, the operator holds the handle 103 and pulls the control block 110. The control block 110 slides in the through groove 109, and the pulling rope 108 drives the squeezing rod 104 to slide in the fixed tube 101. The squeezing rod 104 drives the squeezing head 105 to move away from the optical lens. Then, the side of the fixing ring 1 used to place the optical lens is facing down. The guide angle 203 makes the lens positioned between multiple positioning plates 2 and is limited by the limiting plate 201. The control block 110 is released. At this time, the squeezing rod 104 is reset under the action of the spring 107. At this time, the squeezing head 105 clamps and fixes the optical lens. Then the operator can transfer or inspect the optical lens, thereby effectively improving the clamping effect of the optical lens and avoiding fingerprints sticking on the optical lens when the hand directly handles the optical lens.

[0025] When it is necessary to put down the optical lens, first face the side with the lens toward the placement area, then push the control block 110 downward with your finger to make the squeezing rod 104 slide into the fixing tube 101, release the limit on the optical lens, and thus put down the lens. The operation is simple.

[0026] Example 2: Refer to Figures 1-3 The portable optical lens quick clamp is basically the same as in Embodiment 1. Further, a first protective pad 106 is provided on the extrusion head 105, and a second protective pad 202 is provided on the limiting plate 201.

[0027] The first protective pad 106 and the second protective pad 202 can protect the sides of the optical lens and prevent damage to the optical lens.

[0028] A threaded rod 204 is rotatably mounted on the positioning plate 2, and the threaded rod 204 is threadedly connected to the fixing ring 1. A rotating head 205 is fixedly connected to one end of the threaded rod 204. A sliding rod 206 is fixedly connected to the positioning plate 2, and the sliding rod 206 is slidably mounted on the fixing ring 1.

[0029] The slide bar 206 has multiple equally spaced scale lines 207.

[0030] The position of the positioning plate 2 can be adjusted by rotating the rotating head 205 and rotating the threaded rod 204. At the same time, the scale line 207 set on the slide rod 206 facilitates the precise adjustment of the position of the positioning plate 2, so that optical lenses of different sizes can be clamped, making it more versatile.

[0031] The connecting rod 102 is a flexible metal hose.

[0032] By setting the connecting rod 102 as a flexible metal tube, the entire device can be bent and adjusted easily. The flexible metal tube is similar to the flexible metal tube used in bedside mobile phone holders, and has the ability to be shaped and bent as well as support.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
