[0002] In the assembly process of optical components, the installation and fastening of optical lenses is a crucial link. The lenses are usually installed in the lens barrel and fastened with a pressure ring. This pressure ring design usually uses lightweight materials and has a variety of structural forms to adapt to different application scenarios. The fastening method is generally to design a slot or a round hole on the outer circumference of the pressure ring, and install and fasten it with professional tools. This structural design is not only simple and low-cost, but also can effectively save space. Therefore, it has been widely used in optical components, electronics, electrical components, instruments, hardware and machinery industries.

The rigidity is poor when in use, and the spacing adjustment operation is complicated, which brings inconvenience to the user;

[0005] The other is a knob structure tool, which uses a knob control in the middle, two screws 4 with opposite threads, and a double guide rail design; however, the knurled knob of the device is not convenient to adjust, the disassembly and assembly of the disassembly rod 12 is complicated, the rigidity is also poor, the stroke of the large-size pressing ring cannot be adjusted, the operability is not strong, and it is difficult to meet the needs of users.

[0006] The optical lens pressing ring disassembly and assembly tools in the related art are relatively difficult to operate when facing lens pressing rings of large size, high torque and multiple specifications. Uneven force can also easily damage the disassembly grooves or holes of the parts, which seriously restricts the efficiency and accuracy of optical component assembly. Summary of the invention

[0011] The stroke adjustment mechanism comprises a first adjustment block and a second adjustment block which are arranged opposite to each other or back to back; the end of the first limit block is connected to the first adjustment block by a first locking screw, and the end of the slider is connected to the second adjustment block by a second locking screw; the first adjustment block and the second adjustment block are both extended with a protrusion, and the protrusions are both provided with a through hole for placing a disassembly rod, the disassembly rod is inserted into the through hole, and can be selectively pressed and fixed by the adjustment screw;

[0012] A scale for displaying the distance between the two disassembly rods is arranged on the side of the base.

[0013] In a first possible implementation, the disassembly rod is used to disassemble the pressing ring, one end of which is a flat head adapted to a slotted pressing ring, and the other end is a cylindrical head adapted to a round hole pressing ring.

It should be understood that the terms used in this way are interchangeable where appropriate, so that the embodiments of the present application can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

Moreover, some steps can be omitted, multiple steps can be combined into one step, and / or one step can be decomposed into multiple steps.

[0031] The following is a detailed description of the novel adjustable optical lens pressure ring disassembly device provided in the embodiment of the present application in combination with the accompanying drawings and preferred embodiments.

[0032] See also Figure 1 , the embodiment of the present application provides a novel adjustable optical lens pressing ring disassembly device, such as Figure 1-7 As shown, the device of the embodiment of the present application includes:

[0033] The motion mechanism comprises a base 1, wherein the first limit block 2 and the second limit block 3 which are arranged opposite to each other are fixedly connected to the edge of the base 1, a screw rod 4 and a guide rod 5 are arranged between the first limit block 2 and the second limit block 3, a slider 6 is movably connected to the screw rod 4 and the guide rod 5, and both ends of the screw rod 4 are movably connected to the first limit block 2 and the second limit block 3 respectively, one end of the screw rod 4 passes through the second limit block 3 and is fixedly connected to an adjusting knob 7, so as to form a structure in which the slider 6 reciprocates along the screw rod 4 and the guide rod 5 when the adjusting knob 7 is rotated;

[0034] The stroke adjustment mechanism includes a first adjustment block 8 and a second adjustment block 10 which are arranged opposite to or back to back; the end of the first limit block 2 is connected to the first adjustment block 8 through a first locking screw 9, and the end of the slider 6 is connected to the second adjustment block 10 through a second locking screw 11; the first adjustment block 8 and the second adjustment block 10 are both extended with a protrusion, and the protrusions are both provided with a through hole for placing a disassembly rod 12, the disassembly rod 12 is penetrated in the through hole, and can be selectively tightened and fixed by an adjusting screw 13.

[0035] A scale 14 for displaying the distance between the two disassembly rods 12 is arranged on the side of the base 1 .

[0036] Furthermore, the disassembly rod 12 is used to disassemble the pressing ring, one end of which is a flat head suitable for a slotted pressing ring, and the other end is a cylindrical head suitable for a round hole pressing ring.

[0037] Furthermore, the second limiting block 3 is provided with a groove 15 for accommodating the disassembly rod 12 when the stroke is expanded.

[0038] Furthermore, the guide rod 5 includes a guide rod a and a guide rod b which are parallel to the screw rod 4 and arranged on both sides of the screw rod 4 .

[0039] In some possible implementations, based on the transmission configuration, the rotation of the screw rod 4 can drive the movement of the slider 6, and the movement of the slider 6 is independent of the rotation of the screw rod 4. That is, the rotation of the screw rod 4 can drive the movement of the slider 6, but the movement of the slider 6 will not reversely drive the rotation of the screw rod 4.

[0040] In some possible implementations, the guide rod 5 is inserted into the slide block 6 , and the guide rod 5 can be selectively pressed by the second locking screw 11 to fix the slide block 6 .

[0041] When in use, the motion mechanism realizes the reciprocating motion of the device and adjusts it to the required specifications. The stroke adjustment mechanism realizes the function of increasing the working stroke of the device and expanding the scope of application. The two groups of mechanisms coordinate with each other to achieve the purpose of fast and accurate disassembly and assembly of the pressing ring. Specifically:

[0042] The rotation of the screw rod 4 is controlled by the rotation of the adjusting knob 7, and the precise movement is achieved under the interaction of the forces of the slider 6, driving the disassembly rod 12 on the second adjusting block 10 to move. The distance between the two disassembly rods 12 is determined according to the disassembly groove or hole of the disassembly pressure ring, and can also be determined according to the known groove distance or hole distance. The adjusting knob 7 can be quickly rotated to position it to the required size based on the scale 14 on the side of the device, thereby achieving rapid positioning and disassembly.

[0043] When the disassembly stroke of the large-sized pressing ring is insufficient, the first locking screw 9 and the second locking screw 11 can be disassembled, and the first and second adjusting blocks (8, 10) are rotated 180° and then tightened, so that the distance between the disassembly rods 12 is increased, the stroke is increased, and the disassembly and assembly of the large-sized pressing ring is realized.

[0044] Based on the above technical scheme, the present application effectively meets the requirements of large-size, large-torque, multi-specification, adjustable optical lens pressure ring parts structure for disassembly, assembly, maintenance, care, and repair in terms of multiple specifications, adjustability, no scratching of parts, fast and efficient; for different specifications of pressure rings, the device of the present application can quickly and conveniently disassemble and assemble the optical lens pressure ring, with high rigidity and strong operability, which expands the application scope of optical pressure ring disassembly and assembly, improves disassembly and assembly efficiency, precision and reliability, and reduces the difficulty of manual operation.
