[0024] The following detailed description is provided with reference to specific embodiments. It should be noted that the sequence numbers of the embodiments below are not intended to limit the preferred order of the embodiments. This utility model provides a portable horizontal microscope, which is described in detail below.

[0025] Please see Figure 1 , Figure 1 This is a schematic diagram of the structure of a portable horizontal microscope provided in an embodiment of the present invention. Figure 1In the illustrated embodiment, the portable horizontal microscope mainly includes a microscope body 10, an optical cable head clamp body 20, and a base plate 30. The microscope body 10 mainly includes a microscope lens 101 and a microscope mounting base 102. The microscope lens 101 is fixedly installed in the microscope mounting base 102. The microscope body is mainly used for inspecting optical cable heads. The optical cable head clamp body 20 mainly includes an optical cable head clamp 201 and an optical cable head clamp base 202. The optical cable head clamp 201 is installed on the optical cable head clamp base 202 via a pin 204, and the optical cable head clamp 201 can be rotated (>100°) along the pin 204 for easy placement and clamping of optical cable heads. The optical cable head clamp body 20 is mainly used to clamp optical devices to be inspected, such as optical cable heads or other optical devices. The microscope body 10 can inspect the clamped optical cable heads, mainly checking for defects such as dirt, scratches, and cracks on the end caps and windows of the optical cable heads.

[0026] The portable horizontal microscope also includes a base plate 30. The microscope body 10 and the fiber optic cable clamp body 20 are arranged parallel to each other and fixed above the base plate 30. The center of the microscope mounting base 102 and the center of the fiber optic cable clamp base 202 are at the same height to ensure that the fiber optic cable end cap or window to be observed is located in the center of the field of view of the microscope lens 101. The center line formed by the center of the microscope mounting base 102 and the center of the fiber optic cable clamp base 202 is parallel to the base plate 30. Existing microscopes are usually vertical, that is, the center line formed by the center of the microscope mounting base 102 and the center of the fiber optic cable clamp base 202 is perpendicular to the base plate 30, the lens in the microscope body 10 points downward, and the object to be inspected is located below the lens. However, the portable horizontal microscope provided by this utility model is different from the conventional vertical microscope. In this utility model, the microscope body 10 and the fiber optic cable clamp body 20 are arranged horizontally, and the microscope lens 101 can move horizontally (Y-axis movement) to change the object distance between it and the fiber optic cable clamp 201. The horizontally arranged microscope body 10 and optical cable clamp body 20 are less prone to dust accumulation, which would affect the detection effect.

[0027] exist Figure 1 In the illustrated embodiment, the microscope body 10 can typically move on the base plate 30, including but not limited to displacement in the X, Y, and Z directions, while the fiber optic cable clamp body 20 can typically only move in the Z direction, i.e., in a direction perpendicular to the base plate. This invention primarily achieves focusing on the fiber optic cable clamp and thus detection of the fiber optic cable clamp by adjusting the position of the microscope body. Specifically, in Figure 1In the microscope body 10, a dovetail groove 301 is formed on the base plate 30, which is embedded inside the base plate 30 and opens upwards. The microscope body 10 also includes a dovetail groove slide 103, which is fixed in the dovetail groove 301 and can move along the groove of the dovetail groove 301 to move the microscope lens 101 and adjust its position. The dovetail groove slide 103 can be tightly engaged in the dovetail groove 301 and can slide smoothly in the dovetail groove 301, avoiding displacement of the dovetail groove slide 103 during movement and thus avoiding the need for recalibration; that is, avoiding displacement of the microscope lens during movement and thus avoiding the need for recalibration.

[0028] Meanwhile, in this embodiment of the invention, the microscope body 10 also includes an XY-direction slide 104 and a corresponding XY-direction slide mounting plate 105. The XY-direction slide mounting plate 105 is fixedly mounted on the side of the dovetail slide 103 away from the base plate, while the XY-direction slide 104 is fixed on the XY-direction mounting plate 105 away from the dovetail slide 103. The microscope lens 101 is mounted on the XY-direction slide 104, and the movement of the XY-direction slide 104 drives the microscope lens to move in the XY direction. Furthermore, the presence of the dovetail slide 103 further increases the range of movement of the microscope lens. For example, the microscope body 1 can achieve large-range forward and backward focusing by using the X-direction dovetail slide 103 and the X-direction slide, and can also achieve lateral movement by using the left and right Y-direction slides. The dovetail slide 103 and the dovetail 301 work together to achieve rapid but less precise position adjustment, while the XY-direction slide can be further used to achieve more precise position adjustment. In this invention, the secondary slides of the dovetail slide 103 and the XY slide 104 can achieve a lateral focusing range of more than 30mm, and a single clamping can simultaneously realize the observation, wiping and testing of the fiber end cap and fiber window.

[0029] Please refer to Figure 1 , Figure 1 In the illustrated embodiment, the portable horizontal microscope further includes a shim 40, which is mounted on and fixed to the base plate 30. The fiber optic cable clamp body 20 is fixed above the shim 40 by multiple screws. The shim 40 mainly supports the fiber optic cable clamp 201 and increases its height so that the center of the microscope mounting base 102 and the center of the fiber optic cable clamp base 202 can be aligned at the same height, facilitating the microscope lens to inspect the fiber optic cable clamped by the fiber optic cable clamp body 20. Simultaneously, the fiber optic cable clamp body 20 also includes a Z-axis displacement stage 203, which is fixed to the side of the shim 40 away from the base plate 30, while the fiber optic cable clamp 201 is fixed to the side of the Z-axis displacement stage 203 away from the shim 40. Figure 1In the embodiment shown, the optical cable head clamp 201 can move up and down along the Z direction under the drive of the Z-direction displacement stage 203.

[0030] The optical cable clamp of this invention includes a base, a pressure cap, a silicone pad, and screws. The silicone pad is affixed to the lower surface of the pressure cap. Tightening the screws secures the optical cable head, thus securing the optical cable to be tested. By adjusting the screws, the optical cable clamp can hold optical cables of different specifications, enabling the testing of various types of optical cables. In other embodiments, the screws can also be adjusted to hold other optical devices of different specifications, allowing for the testing of optical devices of different specifications.

[0031] Please refer to Figure 1 ,exist Figure 1 The portable horizontal microscope also includes a dust cover 50, which is positioned between the microscope body 10 and the fiber optic cable clamp body 20. In actual testing scenarios, the fiber optic cable clamp holds the fiber optic cable to be tested, primarily clamping it at the cable end. The cable end cap protrudes from the clamp, closer to the microscope lens. The dust cover 50 mainly covers the cable end cap, preventing dust accumulation at the end cap and the cable window, which could affect subsequent testing. The dust cover 50 is fixed to the base plate with screws. After the cable end is attached, the dust cover 50 can be moved to cover the cable end and prevent external dust from affecting the testing. After testing, the dust cover can be opened for easy unloading.

[0032] Meanwhile, the dust cover 50 mainly includes a first dust cover 501, a second dust cover 502, and a third dust cover 503. The first dust cover 501 is fixedly connected to the base plate 30 by screws. The second dust cover 502 is perpendicular to the base plate 30, that is, perpendicular to the first dust cover 501, and one end of the second dust cover 502 is hinged to the first dust cover 501. The third dust cover 503 can be parallel to the base plate 30 and is movably connected to the other end of the second dust cover 502, making the third dust cover 503 a flip-up structure.

[0033] The portable horizontal microscope provided by this invention also includes a microscope light source, which can be a magnetic light source. It can be fixed to different positions on the base via magnetic attraction, and the base is made of ferromagnetic material. The light source head can be adjusted to the required position and angle of the fiber optic cable head via a serpentine tube. This microscope light source can be rechargeable, facilitating use in scenarios without power, thus expanding the applicability of the portable horizontal microscope. It should also be noted that the portable horizontal microscope provided by this invention can be used not only for inspecting fiber optic cable heads but also for inspecting other optical devices. The horizontally arranged microscope body 10 and fiber optic cable head clamp body 20 also prevent dust accumulation from affecting the inspection results.

[0034] The portable horizontal microscope provided by this utility model also includes a corresponding hand-held toolbox. Through its miniaturized design, the microscope can be quickly packed into the hand-held toolbox for easy carrying.

[0035] In the above embodiments, the descriptions of each embodiment have different focuses. For parts not described in detail in a certain embodiment, please refer to the relevant descriptions in other embodiments.

[0036] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
