Description

Technical Field

[0001] This invention relates to the field of observation equipment technology, and more specifically, to a binocular observation device. Background Technology

[0002] In binocular fusion night vision systems, the primary imaging is typically the low-light image intensifier, which provides rich information and a wide field of view, while the infrared image, used for target recognition and information integration, serves as auxiliary imaging. During product design, based on the left-right eye fusion imaging configuration, the infrared imaging module and optical fusion eyepiece can be designed as a right-eye (or left-eye) module to define the product design. This allows for imaging characteristics where one eye has fusion capabilities and the other has pure low-light capabilities. The images formed by both eyes are then ultimately fused in the brain.

[0003] In actual use, due to design or manufacturing errors in the structure and lens processing, the target seen through the eyepiece may appear as a left-right eye deviation in the field of vision. The brain will then be unable to fuse these two misaligned images into stereoscopic vision, necessitating binocular fusion collimation calibration. However, the adjustment methods in related technologies involve disassembling the machine for adjustment, which is complex and impacts production efficiency.

[0004] In summary, how to provide a binocular fusion collimation adjustment method that does not require disassembly is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0005] In view of this, the purpose of the present invention is to provide a binocular observation device that can be collimated and adjusted without disassembling the device, and is highly operable.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0008] The first imaging component includes a first body and a first collimating lens group located at the eyepiece end or objective lens end of the first body;

[0009] The second imaging component is connected to the first imaging component. The second imaging component includes a second body and a second collimating lens group located at the eyepiece end or objective lens end of the second body.

[0010] A collimation handwheel assembly is rotatably connected to the outer periphery of either the first body or the second body. At least one of the first collimation lens group or the second collimation lens group is connected to its corresponding collimation handwheel assembly, and the collimation centerline of the collimation handwheel assembly deviates from the centerline of its corresponding first collimation lens group or deviates from the centerline of its corresponding second collimation lens group.

[0011] The collimation handwheel assembly drives the first collimation lens group to rotate or drives the second collimation lens group to rotate, so as to adjust the imaging position.

[0012] Preferably, the collimation handwheel assembly is provided with an eccentric groove for connecting the first collimation lens group or the second collimation lens group. The center line of the eccentric groove is offset from the collimation center line, and the collimation center line coincides with the optical axis of the first body or the optical axis of the second body.

[0013] Preferably, the collimation handwheel assembly includes a connecting ring and a lens barrel assembly. The connecting ring is threadedly connected to the first body or the second body, and the lens barrel assembly is connected to the connecting ring and has the eccentric groove inside.

[0014] Preferably, the connecting ring includes a threaded section, the inner ring of which is threadedly connected to the outer ring of the first body or the outer ring of the second body.

[0015] Preferably, the outer periphery of the threaded section of the connecting ring is provided with at least one locking hole, and a locking member is provided in the locking hole. The locking member passes through the locking hole and abuts against the outer periphery of the first body or the outer periphery of the second body.

[0016] Preferably, the inner wall thickness of the lens barrel assembly varies at at least one circumferential location along the axial direction to form the eccentric groove.

[0017] Preferably, the lens barrel assembly includes a lens barrel and an adjusting member. The lens barrel is located inside the connecting ring, and the lens barrel is provided with the eccentric groove. The adjusting member is used to realize the movement of the lens barrel along the collimation centerline.

[0018] Preferably, the outer periphery of the lens barrel is provided with at least one connecting portion, and the outer periphery of the connecting ring is provided with at least one limiting groove corresponding to restrict the rotation of the connecting portion.

[0020] Preferably, the adjusting member is provided with a limiting snap ring and a backlash elimination spring on both sides of its axial direction.

[0021] The present invention provides a binocular observation device, comprising a first imaging component, a second imaging component, and a collimation handwheel assembly; the first imaging component includes a first main body and a first collimating lens group located at the eyepiece end or objective lens end of the first main body; the second imaging component includes a second main body and a second collimating lens group located at the eyepiece end or objective lens end of the second main body; the collimation handwheel assembly is rotatably connected to the outer periphery of the first main body or the outer periphery of the second main body; at least one of the first collimating lens group and the second collimating lens group is connected to its corresponding collimation handwheel assembly, that is, either the first collimating lens group or the second collimating lens group can be configured as follows.

The collimation centerline of the collimation handwheel assembly deviates from the centerline of its corresponding first collimating lens group or its corresponding second collimating lens group. By setting it eccentrically, when the collimation handwheel assembly rotates relative to the first or second main body, it drives the first or second collimating lens group to rotate synchronously, so as to adjust the imaging position. When the imaging of the first imaging component and the second imaging component moves to a reasonable range, the collimation adjustment process is completed.

[0022] The beneficial effects of the present invention are as follows: by rotating the collimation handwheel assembly to the outer periphery of the first body or the outer periphery of the second body, the collimation adjustment can be completed without disassembly in the finished product state, which is simple and convenient to operate and improves applicability.

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] The core of this invention is to provide a binocular observation device that can be collimated and adjusted through external operation without disassembly, making it simple and convenient to operate.

[0036] The binocular observation device provided by this invention includes a first imaging component 2, a second imaging component 3, and a collimation handwheel component 1. Please refer to [reference needed]. Figure 1 The first imaging component 2 and the second imaging component 3 correspond to the left eye and the right eye, respectively.

[0037] The first imaging component 2 and the second imaging component 3 can be binocular observation devices of any spectral type, such as either infrared imaging or low-light imaging, or a fusion of infrared and low-light imaging, without much restriction. For example, if the first imaging component 2 is a fusion of infrared and low-light imaging, and the second imaging component 3 is a low-light imaging component, then the resulting binocular observation device is a night vision device based on dual-spectral fusion imaging that can meet night vision requirements, but it is not limited to this.

[0038] The first imaging assembly 2 includes a first body 21 and a first collimating lens group 22 located at the eyepiece end D2 or the objective lens end D1 of the first body 21. The first collimating lens group 22 is the collimating eyepiece group or the collimating objective lens group of the first imaging assembly 2.

[0039] The second imaging component 3 is connected to the first imaging component 2. Specifically, the connection can be made through a connecting hub to form the overall structure of the binocular observation device, but is not limited thereto.

[0040] The second imaging assembly 3 includes a second main body 31 and a second collimating lens group 32 located at the eyepiece end D2 or the objective lens end D1 of the second main body 31. The second collimating lens group 32 is the collimating eyepiece group or collimating objective lens group of the second imaging assembly 3.

[0041] The collimation handwheel assembly 1 is rotatably connected to the outer periphery of the first body 21 or the outer periphery of the second body 31, when the first imaging assembly 2 and the second imaging assembly 3 are imaging within a suitable range (e.g. Figure 2 (As shown in the triangle), no collimation handwheel assembly 1 is required for operation; when the imaging of the first imaging assembly 2 and the second imaging assembly 3 exceeds a reasonable range (such as... Figure 2 (As shown by the dashed triangle in the diagram), the collimation handwheel assembly 1 rotates relative to the first main body 21 or the second main body 31, thereby rotating the first collimating lens group 22 or the second collimating lens group 32 within the collimation handwheel assembly 1 to perform binocular fusion collimation adjustment. The collimation adjustment process is as follows: Figure 2 The arrows in the diagram indicate the direction.

[0042] In one scenario, the collimation handwheel assembly 1 is located at the objective end D1 of the first body 21 and / or the second body 31; in another scenario, the collimation handwheel assembly 1 is located at the eyepiece end D2 of the first body 21 and / or the second body 31. If the collimation handwheel assembly 1 is located at the objective end D1, then one, two, or three collimation handwheel assemblies 1 can be provided. Specifically, if the first imaging component 2 or the second imaging component 3 is a fusion configuration, such as a low-light imaging + infrared imaging fusion configuration, then two or three collimation handwheel assemblies 1 are required.

[0043] At least one of the first collimating lens group 22 and the second collimating lens group 32 is connected to its corresponding collimating handwheel assembly 1, and the collimation centerline L1 of the collimating handwheel assembly 1 is offset from the centerline of its corresponding first collimating lens group 22 or its corresponding second collimating lens group 32. The collimating handwheel assembly 1 can drive the first collimating lens group 22 or the second collimating lens group 32 to rotate, so as to adjust the imaging position.

[0044] Both the first body 21 and the second body 31 have optical axes. When the collimation handwheel assembly 1 is installed on the first body 21, the collimation centerline L1 of the collimation handwheel assembly 1 and the optical axis of the first body 21 are collinear. When the collimation handwheel assembly 1 is installed on the second body 31, the collimation centerline L1 of the collimation handwheel assembly 1 and the optical axis of the second body 31 are collinear. The collimation centerline L1 is as follows: Figure 7 The meaning is as shown.

[0045] In one scenario, the collimation centerline L1 of the collimation handwheel assembly 1 is collinear with the optical axis of the first main body 21, and the centerline of the first collimation lens group 22 is offset from the collimation centerline L1, meaning the first collimation lens group 22 is eccentrically positioned. When the entire collimation handwheel assembly 1 rotates relative to the first main body 21, the first collimation lens group 22 rotates and can be adjusted in position, which means it can adjust the position of the corresponding image of the first imaging component 2 and perform collimation calibration adjustment.

[0046] In another scenario, the collimation centerline L1 of the collimation handwheel assembly 1 and the optical axis of the second main body 31 are collinear, and the centerline of the second collimation lens group 32 is offset from the collimation centerline L1, that is, the second collimation lens group 32 is eccentrically set. When the entire collimation handwheel assembly 1 rotates relative to the second main body 31, the second collimation lens group 32 rotates and can be adjusted in position, that is, the position of the image corresponding to the second imaging component 3 can be adjusted to perform collimation calibration adjustment.

[0047] If the collimation handwheel assembly 1 is located at the eyepiece end D2, then one or two collimation handwheel assemblies 1 can be provided. For example... Figure 2 As shown, two collimation handwheel assemblies 1 can be provided at the eyepiece end D2, corresponding to the first collimating lens group 22 and the second collimating lens group 32 respectively. When the left and right eye imaging deviation exceeds a reasonable range, the positions of the correspondingly eccentrically positioned first collimating lens group 22 and second collimating lens group 32 are adjusted by rotating the two collimation handwheel assemblies 1, so that the imaging of the first imaging component 2 and the second imaging component 3 are moved to a reasonable range, at which point the brain can normally fuse the images from both eyes into a stereoscopic image.

[0048] In this embodiment, the collimation handwheel assembly 1 is rotatably connected to the outer periphery of the first body 21 or the outer periphery of the second body 31. Specifically, the first body 21 and the second body 31 can be the lens barrel or other fixed components, as long as they can satisfy the effect of reliable rotation of the collimation handwheel assembly 1.

[0049] In this embodiment, the eccentric setting of the first collimating lens group 22 and the second collimating lens group 32 can be met by mechanical positioning. For example, the mounting position of the collimating lens group can be set to be eccentric so that the collimating lens group can meet the eccentricity after installation and meet the collimation calibration requirements.

[0050] It should be noted that the actual rotation of the collimation handwheel assembly 1 that drives the first collimation lens group 22 or the second collimation lens group 32 is for fine adjustment. The specific degree of fine adjustment is related to the degree of eccentricity. For example, if the eccentricity design value is 0.2mm, then collimation calibration can be performed using this eccentricity design value.

[0051] In this embodiment, the collimation handwheel assembly 1 is rotatably connected to the outer periphery of the first body 21 or the second body 31. Therefore, the position adjustment of the first collimating lens group 22 or the second collimating lens group 32 is completed by external adjustment, without disassembly or assembly. The operation is simple and convenient, and the applicability is stronger.

[0052] Based on the above embodiments, please refer to Figure 4 , Figure 5 , Figure 7 The collimation handwheel assembly 1 is provided with an eccentric groove 126. The eccentric groove 126 is used to connect the first collimating lens group 22 or the second collimating lens group 32. The center line L2 of the eccentric groove 126 is offset from the collimation center line L1, and the collimation center line L1 coincides with the optical axis of the first body 21 or the optical axis of the second body 31.

[0053] The eccentric groove 126 can be set to one, two or more quantities according to the needs, and the specific quantity can be determined according to the actual situation.

[0054] Specifically, when the first collimating lens group 22 is located in the eccentric groove 126 within the collimating handwheel assembly 1 corresponding to the first imaging component 2, during collimation adjustment, the first collimating lens group 22 within the eccentric groove 126 can be rotated by rotating the collimating handwheel assembly 1 relative to the first main body 21, thereby adjusting the image position. The rotation process of the second collimating lens group 32 is the same as described above and will not be detailed further.

[0055] The eccentric groove 126 specifically refers to its eccentric position, not its eccentric shape. The shape of the eccentric groove 126 is determined in conjunction with the form of the first collimating lens group 22 or the second collimating lens group 32, without excessive restrictions. For example... Figure 5 The lens barrel assembly 12 includes a lens barrel 121, which is divided into an inner barrel portion and an outer barrel portion. With the eccentric groove 126 provided, the outer barrel portion of the lens barrel 121 is coaxially arranged with the first collimating lens group 22, while the inner barrel portion is not coaxially arranged with the first collimating lens group 22; or, the outer barrel portion is coaxially arranged with the second collimating lens group 32, while the inner barrel portion is not coaxially arranged with the second collimating lens group 32.

[0056] For example, if both the first imaging component 2 and the second imaging component 3 are equipped with corresponding collimation handwheel components 1, the two collimation handwheel components 1 can be rotated during calibration to adjust the first collimation lens group 22 and the second collimation lens group 32 respectively. After the image is moved to a reasonable range, the collimation calibration process ends.

[0057] Based on any of the above embodiments, please refer to Figure 3 The collimation handwheel assembly 1 includes a connecting ring 11 and a lens barrel assembly 12. The connecting ring 11 is threaded to the first body 21 or the second body 31, and the lens barrel assembly 12 is connected to the connecting ring 11 and has an eccentric groove 126 inside.

[0058] The connecting ring 11 is threaded to the first body 21 or the second body 31. By screwing the connecting ring 11 in or out of the thread, the corresponding lens barrel assembly 12 can be rotated synchronously, that is, the collimating lens group inside the lens barrel assembly 12 can be rotated, so as to perform collimation calibration, ensure that the image observed by the binoculars is within a reasonable range, and the brain can normally synthesize the binocular images into a stereoscopic image.

[0059] Please refer to Figure 3 , Figure 5 The lens barrel assembly 12 has an eccentric groove 126 inside. The eccentric groove 126 can be formed by integral molding or by splicing parts, without limitation.

[0060] Based on any of the above embodiments, please refer to Figure 4 , Figure 5 The connecting ring 11 includes a threaded section 112, the inner ring of which is threadedly connected to the outer ring of the first body 21 or the outer ring of the second body 31.

[0061] The inner ring of the threaded section 112 is threadedly connected to the outer ring of the first body 21; or, the inner ring of the threaded section 112 is threadedly connected to the outer ring of the second body 31. When adjusting the imaging position by rotating the connecting ring 11, it can be manually rotated on the outside, which is convenient for operation.

[0062] Specifically, when adjusting the imaging position, the threaded section 112 can be rotated relative to the first main body 21 or the second main body 31 by rotating the connecting ring 11. This allows the first collimating lens group 22 or the second collimating lens group 32 within the lens barrel assembly 12 to rotate. Since the collimation centerline of the collimation handwheel assembly 1 is offset from the collimating lens group, the imaging position can be adjusted when the first collimating lens group 22 or the second collimating lens group 32 rotates, so that the imaging of the first imaging component 2 and the second imaging component 3 are placed within a reasonable range. At this time, the brain can normally fuse the images from both eyes into a stereoscopic image.

[0063] Based on any of the above embodiments, please refer to Figure 5The outer periphery of the connecting ring 11 is provided with at least one locking hole 1121. Specifically, the outer periphery of the threaded section 112 of the connecting ring 11 is provided with a locking hole 1121. A locking member is provided in the locking hole 1121. The locking member passes through the locking hole 1121 and abuts against the outer periphery of the first body 21 or the outer periphery of the second body 31.

[0064] After the collimation adjustment is completed by the collimation handwheel assembly 1 and the imaging movement is determined to be within a reasonable range, the locking member passes through the locking hole 1121 of the threaded section 112 and is pressed against the first body 21 or the second body 31 to complete the locking operation of the collimation handwheel assembly 1, avoid imaging deviation caused by accidental contact, and ensure the effect of observation and use.

[0065] Taking the locking member passing through the locking hole 112 and pressing against the first body 21 as an example, when adjusting the image position of the first imaging component 2, the locking member is loosened to release the contact with the first body 21 when the collimation handwheel component 1 needs to be rotated. After the rotation adjustment is completed, the locking member is tightened to contact the first body 21, and the locking is completed after the collimation calibration process.

[0066] The specific locking components can be external screws, external bolts, etc. The specific number can be set according to the actual situation. For example, multiple components can be set along the outer periphery of the connecting ring 11 so that locking can be performed from multiple directions, ensuring reliable locking after the collimation calibration process is completed, and avoiding imaging deviation caused by accidental contact.

[0067] If the locking component is a screw, then the locking hole 112 is a threaded hole, and the screw and the threaded hole are connected by threads to ensure reliable connection.

[0068] Based on any of the above embodiments, please refer to Figure 5 The inner wall thickness of the lens barrel assembly 12 varies at at least one circumferential location along the axial direction, so as to form an eccentric groove 126.

[0069] One side of the lens barrel assembly 12 is connected to the connecting ring 11, and the center line of the connecting ring 11 is centered. Specifically, the centering here means that it is aligned with the optical axis of the first main body 21 or the second main body 31. The other side of the lens barrel assembly 12 is provided with an eccentric groove 126, which is formed by a non-uniform wall thickness region inside the lens barrel assembly 12.

[0070] For example, at a certain circumferential position, one half of the structure has a thicker wall thickness and the other half has a thinner wall thickness. The inner diameter of both halves of the structure corresponds to the outer circumferential size of the collimating lens group. In this way, after the collimating lens group is installed in the eccentric groove 126 formed by the two halves of the structure, an eccentric effect can be achieved.

[0071] There are no specific restrictions on the non-uniformity of wall thickness; it can be adapted to the actual collimating lens group structure. In cases where non-uniform wall thickness regions are formed, the eccentric groove 126 structure can be directly formed through integral molding, resulting in a simple structure and low cost.

[0072] Based on any of the above embodiments, please refer to Figure 5 , Figure 7 The lens barrel assembly 12 includes a lens barrel 121 and an adjusting member 122. The lens barrel 121 is located inside the connecting ring 11 and is provided with an eccentric groove 126. The adjusting member 122 is connected to the lens barrel 121 and is used to realize the movement of the first collimating lens group 22 or the second collimating lens group 32 provided in the eccentric groove 126 along the collimation centerline L1.

[0073] When performing collimation adjustment: The lens barrel 121 is specifically a component with an eccentric groove 126, which can be directly machined in an integral form. The lens barrel 121 is used to install the lens structure corresponding to the first collimating lens group 22 or the second collimating lens group 32. The lens barrel 121 is located inside the connecting ring 11. When the connecting ring 11 is screwed in and out, the lens barrel 121 can rotate accordingly to perform collimation adjustment.

[0074] When adjusting diopter: The adjusting element 122 can move either the first collimating lens group 22 or the second collimating lens group 32 to achieve diopter adjustment. By moving the lens group to change the equivalent focal length, diopter adjustment is achieved, enabling people with different vision to see clear images.

[0075] In one embodiment, the adjusting member 122 can generate a pushing force by rotating. This pushing force can be transmitted by contacting the lens barrel 121. The lens barrel 121 is limited to translation on the connecting ring 11. Thus, the rotation of the adjusting member 122 can drive the lens barrel 121 to move along the corresponding collimation center line L1, that is, the movement of the first collimating lens group 22 or the second collimating lens group 32 in the lens barrel 121 can be realized, so as to perform diopter adjustment.

[0076] In another embodiment, the adjusting member 122 generates a pushing force by translation. Manually pushing or pulling the adjusting member 122 can drive the lens barrel 121 in contact with it to move in the direction of the corresponding collimation center line L1. This enables the movement of the first collimating lens group 22 or the second collimating lens group 32 within the lens barrel 121, thereby enabling diopter adjustment.

[0077] For the specific solution of diopter adjustment, a collimation handwheel assembly 1 is set at the eyepiece end D2 of both the first body 21 and the second body 31. The lens group is moved by the pushing force generated by the adjustment component 122 corresponding to the two collimation handwheel assemblies 1, so as to meet the diopter adjustment needs and enable people with different vision to see clear images.

[0078] Based on any of the above embodiments, please refer to Figure 4 , Figure 5 , Figure 6 The outer periphery of the lens barrel 121 is provided with at least one connecting part 125, and the outer periphery of the connecting ring 11 is provided with at least one limiting groove 1111 corresponding to restrict the rotation of the connecting part 125. The connecting part 125 extends out of the limiting groove 1111 and is threadedly connected to the adjusting member 122.

[0079] Please refer to the following for details. Figure 6 When adjusting diopter, the connecting ring 11 is fixed to the first body 21 or the second body 31, and the connecting part 125 is placed in the limiting groove 1111. The limiting groove 1111 is only used to restrict the rotation of the connecting part 125. The connecting part 125 can move in the limiting groove 1111 to realize the translation of the lens group in the lens barrel 121, that is, to achieve the effect of diopter adjustment.

[0080] Specifically, the limiting groove 1111 restricts rotation by fitting against two opposing sidewalls of the connecting portion 125, while the other two opposing sidewalls of the connecting portion 125 have a movable distance from the limiting groove 1111 to meet the requirement of the connecting portion 125 being movable. The sidewalls of the connecting portion 125 mentioned here, such as... Figure 5 There is a movable distance between the left and right side walls and the limiting groove 1111, while the upper and lower side walls are attached to the limiting groove 1111.

[0081] When the adjusting member 122 rotates, due to the limiting groove 1111, the connecting part 125 can only translate. Therefore, the collimating lens group in the lens barrel 121 can only move along the collimating center line L1 to achieve diopter adjustment.

[0082] The adjusting component 122 can be a handwheel structure, which is convenient for manual rotation. Without disassembling the internal structure, the force can be transmitted to the connecting part 125 by rotating the external adjusting component 122 to achieve reliable translation of the lens barrel 121. This ensures the reliability and effectiveness of diopter adjustment. The operation is simple and convenient. The operator can rotate the adjusting component 122 from the outside, and it has good applicability.

[0083] In this embodiment, the number and shape of the limiting grooves 1111 on the outer periphery of the connecting ring 11 that can restrict the rotation of the connecting part 125 are determined according to the actual form of the connecting part 125. For example, if multiple square limiting grooves 1111 are distributed at intervals on the outer periphery of the connecting ring 11, then multiple square connecting parts 125 are correspondingly arranged on the outer periphery of the lens barrel 121, so that when the adjusting member 122 rotates, reliable translation of the collimating lens assembly can be achieved through the connection between the connecting parts 125 at multiple positions and the adjusting member 122. Specifically, the outer periphery of the lens barrel 121 is provided with at least one connecting part 125, preferably one, two, three, four, etc., and the present invention does not limit this.

[0084] Based on the setting of the adjustment component 122, the lens barrel 121 can be moved horizontally without disassembling the internal structure in the whole state, which can meet the diopter adjustment requirements; and based on the setting of the connecting ring 11, the lens barrel 121 can be rotated without disassembling the internal structure in the whole state, so as to meet the collimation parameter adjustment requirements.

[0085] Based on any of the above embodiments, please refer to Figure 5 The connecting ring 11 includes a main body section 111, the main body section 111 is provided with a limiting groove 1111, and the adjusting member 122 is located outside the main body section 111 and is threadedly connected to the connecting part 125.

[0086] The main body section 111 and the threaded section 112 are connected. One end of the limiting groove 1111 of the main body section 111 extends to connect with the threaded section 112, and the other end extends away from the threaded section 112. The adjusting member 122 is located outside the main body section 111 and can be threadedly connected to the connecting part 125 extending out of the limiting groove 1111. When the adjusting member 122 rotates, and the connecting ring 11 is fixed to the first main body 21 or the second main body 31, the rotation of the adjusting member 122 outside the main body section 111 causes the connecting part 125 to move, that is, to realize the translational movement of the lens barrel 121, which can meet the diopter adjustment requirements.

[0087] Based on any of the above embodiments, please refer to Figure 3 , Figure 4 The adjusting member 122 is provided with a limiting snap ring 124 and a gap-eliminating spring 123 on both sides of the axial direction. Both the limiting snap ring 124 and the gap-eliminating spring 123 are connected to the outer periphery of the connecting ring 11.

[0088] The backlash-eliminating spring 123 is specifically sleeved on the outer periphery of the connecting ring 11 and abuts against one side of the adjusting member 122 along the axial direction. The backlash-eliminating spring 123 utilizes its wave-shaped structural deformation to achieve axial pre-tightening. By gradually flattening the wave shape, the fit clearance is eliminated, achieving precise pre-tightening. One side of the backlash-eliminating spring 123 abuts against one side of the adjusting member 122 along the axial direction, and the other side abuts against the limiting end face on the outer periphery of the connecting ring 11. The limiting end face is connected to the limiting groove 111. When the connecting ring 11 is connected to the first body 21 or the second body 31, the backlash-eliminating spring 123 is clamped between the limiting end face and the end face of the adjusting member 122.

[0089] The limiting spring 124 is located at the end of the connecting ring 11 away from the first body 21 or the second body 31. The limiting spring 124 is installed in the groove structure on the connecting ring 11 and can limit the range of movement of the adjusting member 122 axially to the other side. When it is necessary to disassemble or assemble the adjusting member 122, the limiting spring 124 can be removed, which is simple and convenient.

[0090] In this embodiment, the adjusting member 122 can rotate within the range between the gap-eliminating wave spring 123 and the limiting snap ring 124. The rotation range of the adjusting member 122 corresponds to the moving distance of the lens barrel 121, which is also the diopter adjustment range.
