DETAILED DESCRIPTION

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0021] The utility model discloses a microscope focusing optical lens, such as Figure 1-5 As shown, it includes a sleeve 1 installed on the microscope and a focusing optical lens body 2 arranged inside the sleeve 1. Rotation grooves 101 are provided on both sides of the interior of the sleeve 1. One side of the interior of the two rotation grooves 101 is rotatably connected to a threaded rod 103, and the other side of the interior of the two rotation grooves 101 is fixedly installed with a slide rod 106. The outer surface of the threaded rod 103 is threadedly connected to a mounting ring 107, and the mounting ring 107 is slidably connected to the slide rod 106. When the threaded rod 103 rotates, it will drive the mounting ring 107 to rise and fall along the slide rod 106.

[0022] The focusing optical lens body 2 is located inside the mounting ring 107 . When the mounting ring 107 is raised or lowered as the threaded rod 103 rotates, the focusing optical lens body 2 is driven to be raised or lowered to fine-tune its height.

[0023] The two rotating grooves 101 are located on one side of the threaded rod 103 and a driving hole 105 is opened. The internal rotation of the driving hole 105 is connected to the second gear 104. The first gear 102 is fixedly installed on the upper outer surface of the threaded rod 103, and the first gear 102 is engaged with the second gear 104. When the second gear 104 rotates, it will drive the first gear 102 and the threaded rod 103 to rotate.

[0024] The outer surface of the sleeve 1 is rotatably connected to a limit ring 109, and a gear ring 108 is fixedly installed on the top surface of the limit ring 109. The gear ring 108 is engaged with the second gear 104. The limit ring 109 is rotated to drive the gear ring 108 to rotate, and the rotating gear ring 108 will drive the second gear 104 to rotate.

[0025] A plurality of limiting holes 110 are provided on the outer surface of the limiting ring 109, a fixing rod 111 is fixedly installed on one side of the outer surface of the sleeve 1, a telescopic sleeve 112 is fixedly installed on one side of the fixing rod 111, and a first spring 113 is fixedly installed on one side of the telescopic sleeve 112. A limiting block 115 is fixedly installed on one end of the first spring 113 located at the opening of the telescopic sleeve 112. When the limiting block 115 moves toward the inside of the telescopic sleeve 112, it will squeeze the first spring 113.

[0026] The limit block 115 is located on one side of the first spring 113 and is fixedly installed with a movable rod 114, and the movable rod 114 passes through the inside of the first spring 113, a part of the movable rod 114 is located outside the telescopic sleeve 112, and the other part of the movable rod 114 is located inside the telescopic sleeve 112. The movable rod 114 is pulled toward the outside of the telescopic sleeve 112 to drive the limit block 115 to move toward the inside of the telescopic sleeve 112, so that the limit block 115 is pulled out of the limit hole 110, and then the limit ring 109 can be rotated to adjust the height of the mounting ring 107. After the adjustment is completed, the movable rod 114 is released, and the squeezed first spring 113 will push the limit block 115 to reset, so that the limit block 115 is inserted into the limit hole 110 to prevent the limit ring 109 from continuing to rotate.

[0027] The size of the limiting block 115 is the same as the size of the limiting hole 110 .

[0028] A connecting ring 201 is provided on the outer surface of the focusing optical lens body 2, and shrinkage holes 202 are provided on both sides of the interior of the connecting ring 201. A second spring 203 is fixedly installed on one side of the interior of the two shrinkage holes 202, and a mounting block 204 is fixedly installed on one end of the two second springs 203 located at the opening of the shrinkage hole 202. When the mounting block 204 moves toward the interior of the shrinkage hole 202, it will squeeze the second spring 203.

Pull the two levers 205 closer to each other to move the two mounting blocks 204 to the inside of the shrinkage hole 202, and then place the connecting ring 201 inside the mounting ring 107 to insert the two guide blocks 207 into the two guide grooves 1072. Then release the two levers 205, and the squeezed second spring 203 will push the mounting block 204 to reset, so that the mounting block 204 is inserted into the mounting hole 1071 to complete the installation of the focusing optical lens body 2.

[0031] The working principle of the present invention is as follows: pull the two levers 205 closer to each other to move the two mounting blocks 204 to the inside of the shrinkage hole 202, and then place the connecting ring 201 inside the mounting ring 107 to insert the two guide blocks 207 into the two guide grooves 1072, and then release the two levers 205, the squeezed second spring 203 will push the mounting block 204 to reset, so that the mounting block 204 is inserted into the mounting hole 1071, thereby completing the installation of the focusing optical lens body 2, and then install the sleeve 1 on the microscope through a threaded connection. During the process, the movable rod 114 is pulled toward the outside of the telescopic sleeve 112 to drive the limit block 115 to move toward the inside of the telescopic sleeve 112, so that the limit block 115 is pulled out of the limit hole 110, and then the limit ring 109 can be rotated, which in turn drives the gear ring 108 to rotate, and the rotating gear ring 108 drives the second gear 104 to rotate, and the second gear 104 drives the first gear 102 and the threaded rod 103 to rotate, which can drive the mounting ring 107 to rise and fall along the slide rod 106 to adjust the height of the focusing optical lens body 2.
