DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] like Figure 1-4 An optical instrument that is easy to maintain is shown, including a main body 1, which is a cylinder with a groove formed on it. The first rotating wheel 2 and the second rotating wheel 8 are both provided with holes that are compatible with the main body 1. The first rotating wheel 2 and the second rotating wheel 8 are both arranged in the groove of the main body 1. The first rotating wheel 2 and the second rotating wheel 8 can rotate on the main body 1. The function of the first rotating wheel 2 and the second rotating wheel 8 is to drive the first connecting bracket 3 and the second connecting bracket to rotate.

[0022] A first connecting bracket 3 is fixedly connected to one side of the first rotating wheel 2 . The function of the first connecting bracket 3 is to connect the main body 1 and the main lens barrel 5 so that the main lens barrel 5 can be adjusted on the main body 1 .

[0023] The first connecting bracket 3 is detachably connected to the connecting block 4. A groove is opened on one side of the first connecting bracket 3. The inner wall of the groove is fixedly connected to the first spring 10. The first spring 10 is fixedly connected to the clamping block 11. The clamping block 11 is in the shape of a triangle. When it is clamped, it faces the inclined surface and can be inserted quickly and easily. After being clamped, if you want to pull it out, you will face the right-angled surface and cannot pull it out directly, which makes the connection more stable.

[0024] The connection block 4 is provided with a hole matched with the clamping block 11 . The length of the clamping block 11 is the same as that of the hole. The clamping block 11 can be clamped in the hole on the connection block 4 , and the connection block 4 is clamped with the first connection bracket 3 through the clamping block 11 .

[0025] A second spring 12 is fixedly connected to the inner wall of the hole of the connecting block 4, and a push block 13 is fixedly connected to the second spring 12. The size of the push block 13 is adapted to the clamping block 11. The push block 13 can push the clamping block 11 out of the hole of the connecting block 4, thereby ending the clamping state of the connecting block 4 and the first connecting bracket 3. At this time, the connecting block 4 and the first connecting bracket 3 are in a separated state.

[0026] A button 14 is fixedly connected to the push block 13. The button 14 is arranged throughout the connecting block 4. The button 14 is also located in the middle of the second spring 12. After pressing the button 14, the push block 13 will be pushed inward by force. During the pushing process, the push block 13 will pull the second spring 12 to move. The inward movement of the push block 13 will push the block 11 in the hole of the connecting block 4 to move outward. When the block 11 is completely out of the hole, the connecting block 4 is separated from the first connecting bracket 3. At this time, the main lens barrel 5 can be removed from the main body 1. After the main lens barrel 5 is removed, release the button 14, the button 14 and the push block 13 will return to their original state due to the resilience of the second spring 12, and the block 11 on the first connecting bracket 3 will also return to its original position due to the resilience of the first spring 10.

[0027] The connecting block 4 is fixedly connected with a main lens barrel 5 , which is a truncated cone-shaped cylinder with openings at both ends. An objective lens assembly 6 is arranged at one end of the main lens barrel 5 , and an eyepiece assembly 7 is arranged at the other end of the main lens barrel 5 .

[0028] The objective lens assembly 6 includes an objective lens barrel 601, which is detachably connected to the main lens barrel 5. The inner wall of the objective lens barrel 601 is provided with a thread, and the main lens barrel 5 is provided with a thread matching the thread. The objective lens barrel 601 is connected to the main lens barrel 5 by a threaded connection. The inner wall of the objective lens barrel 601 is fixedly connected with a buckle, and the buckle is clamped with an objective lens 602. When the objective lens 602 is damaged, it can be directly removed, and then the objective lens 602 can be cleaned, repaired or replaced.

[0029] The eyepiece assembly 7 includes an eyepiece barrel 701, which is detachably connected to the main lens barrel 5. The inner wall of the eyepiece barrel 701 is provided with a thread, and the main lens barrel 5 is provided with a thread matching the thread. The eyepiece barrel 701 is connected to the main lens barrel 5 in a threaded connection manner. The inner wall of the eyepiece barrel 701 is fixedly connected with a hook, and the hook is connected to an eyepiece lens 702. When the eyepiece lens 702 is damaged, it can be directly removed, and then the eyepiece lens 702 can be cleaned, repaired or replaced. A focusing knob 703 is also provided on the eyepiece barrel 701, and the focusing knob 703 can focus the telescope to make the viewed object clearer.

[0030] The main body 1 is rotatably connected to the second rotating wheel 8, and the second rotating wheel 8 is fixedly connected to the second connecting bracket 9. One end of the second connecting bracket 9 is fixedly connected to the second rotating wheel 8, and the other end of the second bracket 9 is an arc clamping ring, and the shape and size of the clamping ring are adapted to the main lens barrel 5. The clamping ring is made of elastic plastic, and the main lens barrel 5 can be clamped on the second connecting bracket 9.

[0031] The working principle of the utility model is as follows:

[0032] When the lens barrel of the utility model is damaged, the button 14 on the connecting block 4 can be pressed to apply force to the push block 13. After being applied force, the push block 13 overcomes the resilience of the second spring 12 and is pushed inward, and the clamping block 11 receives the thrust of the push block 13 and moves inward. When the clamping block 11 is separated from the hole on the connecting block 4, the main lens barrel 5 can be removed from the main body 1 for maintenance. The eyepiece assembly 7 and the objective lens assembly 6 at both ends of the main lens barrel 5 can be removed, so that the objective lens 602 and the eyepiece lens 702 can be repaired and replaced. After the maintenance is completed, the objective lens 602 and the eyepiece lens 702 are assembled, and the main lens barrel 5 can be directly clamped on the main body 1.

[0033] The above embodiments are only used to help understand the method and core idea of ​​the utility model. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made to the utility model without departing from the principle of the utility model, and these improvements and modifications also fall within the scope of protection of the claims of the utility model.
