Description
Technical Field
[0001] This utility model relates to the field of optical equipment technology, specifically to a detachable tube camera lens interface conversion component. Background Technology
[0002] In the field of optical equipment, the lens interface conversion assembly is a crucial component connecting lenses of different specifications to the camera body. Its design and performance directly affect the ease of use and compatibility of the equipment. Especially in scenarios requiring frequent lens changes or adjustments to lens configurations, the efficiency and stability of the interface conversion assembly are paramount. However, existing lens interface conversion assemblies generally suffer from complex structures and cumbersome operations, making it difficult for users to quickly install and remove lenses in practical use. Furthermore, traditional interface conversion assemblies typically rely on threaded fixings or single snap-fit structures. This design not only increases operational time costs but also easily leads to component wear due to repeated disassembly and assembly, affecting connection reliability and lifespan. Simultaneously, the existing technology lacks a solution that balances quick disassembly and assembly with a stable connection, which to some extent limits the flexible application of bullet camera lenses in various scenarios. Therefore, developing a simple, easy-to-operate, and highly stable disassembly-and-assembly bullet camera lens interface conversion assembly has become an urgent problem to be solved in the current technical field. This utility model aims to achieve quick disassembly and assembly and reliable connection of the lens interface conversion assembly through innovative structural design, thereby improving the overall efficiency of the equipment and the user experience. Utility Model Content
[0003] This invention aims to solve the problems of inconvenient disassembly and assembly in existing lens interface conversion components, especially the drawbacks of complex operation, unstable connection, and difficult maintenance when quickly changing lenses. To address these issues, this invention proposes a detachable bullet camera lens interface conversion component, which achieves quick disassembly and assembly and stable connection through optimized structural design.
[0004] This utility model provides a detachable lens interface conversion assembly for a bullet camera, including a base, a body, a lens, a mounting ring, a conversion ring, a lever, a sliding frame, a locking block, and a spring. The base serves as the foundation of the entire assembly, supporting and fixing other components. The body is mounted on the base to house and fix the internal structure of the lens interface conversion assembly. The lens is mounted on the front end of the body and connected to it via an interface. The mounting ring is located outside the body and is used to fix and adjust the lens position; it has slots and grooves for engaging with corresponding components on the conversion ring. The conversion ring is located inside the body and is used to convert between different lens interfaces; its inner wall has a sliding groove that engages with the sliding frame, allowing the sliding frame to move within a certain range. The lever is located on the conversion ring and is used for manual operation to quickly detach and assemble the interface. The sliding frame is installed in the sliding groove and connected to the locking block via a connecting rod, enabling the locking block to extend and retract. The locking block engages with the locking groove to lock the interface position. The spring is installed inside the sliding frame and provides elasticity to keep the locking block in the locked state.
[0005] Furthermore, the design of the sliding groove and the sliding frame ensures that the sliding frame can move smoothly within the groove, thereby driving the locking block to complete the locking or unlocking action. The inner surface of the sliding groove is precision-machined to form a smooth track with a certain degree of frictional resistance, making the movement of the sliding frame within the groove both smooth and controllable. The external dimensions of the sliding frame match the sliding groove, and it is manufactured using high-precision machining technology to ensure the positioning accuracy of the sliding frame within the groove. The ends of the sliding frame are equipped with guide structures to guide the sliding frame to move along the predetermined trajectory of the sliding groove, preventing the sliding frame from deviating from the track. In addition, both ends of the sliding groove are equipped with limiting devices to limit the maximum range of movement of the sliding frame, preventing the sliding frame from dislodging from the sliding groove due to excessive movement.
[0006] Specifically, the connecting rod transmits the movement of the sliding frame to the locking block, ensuring that the locking block can accurately enter or exit the slot, enabling quick assembly and disassembly of the interface. One end of the connecting rod is hinged to the sliding frame, and the other end is hinged to the locking block, forming a linkage mechanism. When the sliding frame moves along the slide groove, the connecting rod drives the locking block to move synchronously, causing the locking block to extend or retract from the slot. The length and angle of the connecting rod are precisely calculated to ensure that the movement path of the locking block perfectly matches the position of the slot. The connecting rod is made of high-strength metal material with good tensile strength and bending resistance, maintaining stable mechanical properties during long-term use. In addition, the hinge point of the connecting rod is equipped with a lubrication device to reduce frictional resistance during movement and improve the service life of the connecting rod.
[0007] The spring, installed within the slide frame, provides elastic restoring force, ensuring the locking block remains locked when no external force is applied, thus enhancing the stability of the interface connection. One end of the spring is fixed to the bottom of the slide frame, while the other end contacts the top of the slide frame, creating a compressed state. As the slide frame moves along the groove, the spring is further compressed, storing elastic potential energy. When the external force is removed, the spring releases the stored elastic potential energy, pushing the slide frame back to its original position, allowing the locking block to re-enter the groove. The spring's elastic coefficient is precisely calculated to ensure that the provided force meets the locking requirements of the locking block without causing excessive resistance to the movement of the slide frame. The spring is made of alloy steel with excellent fatigue resistance, maintaining stable elastic characteristics during repeated compression and release.
[0008] Furthermore, the design of the toggle block facilitates manual operation by the user. Simply moving the toggle block drives the sliding frame and locking block to complete the assembly and disassembly actions. The toggle block's shape is ergonomically optimized, featuring a curved surface that conforms to the palm of the hand, making it easier for the user to apply force. The bottom surface of the toggle block fits tightly against the outer surface of the conversion ring and is fixed to the conversion ring with screws, ensuring that the toggle block will not loosen or shift during operation. The inner side of the toggle block has a raised structure that contacts the end of the sliding frame, transmitting the user's operating force to the sliding frame. When the user moves the toggle block, the raised structure pushes the sliding frame along the slide groove, thereby causing the locking block to complete the locking or unlocking action. The surface of the toggle block is treated with an anti-slip coating to increase friction during user operation and prevent slippage leading to operational errors.
[0009] Specifically, the slot and groove design of the mounting ring ensures the stability of the interface during use, preventing loosening or detachment. The shapes of the slots and grooves are precisely calculated to perfectly match the shape of the card block, ensuring a secure lock after the card block enters the groove. The inner surfaces of the slots and grooves are hardened, providing high wear resistance and impact resistance, maintaining stable mechanical properties over long-term use. The depth of the slots and grooves is optimized to ensure sufficient insertion of the card block in the locked state, preventing it from dislodging due to external forces. Furthermore, the edges of the slots and grooves are chamfered to guide the card block smoothly into the groove, reducing frictional resistance between the card block and the groove.
[0010] Furthermore, the base, cylinder, lens, and adapter ring are designed independently, facilitating production and maintenance and improving overall reliability and flexibility. The base has mounting holes at the bottom for bolting it to the equipment, ensuring it doesn't shift during use. The inner surface of the cylinder is precision-machined into a smooth cylindrical cavity to house the internal structure of the lens interface adapter assembly. The outer surface of the cylinder has threads for engaging with the mounting ring to secure and adjust the lens. The lens interface end has a locating pin that engages with the cylinder interface end to prevent rotation or shifting during installation. The outer surface of the adapter ring has anti-slip textures to increase friction during operation and prevent slippage.
[0011] Specifically, the adapter ring is designed to be compatible with various lens interfaces of different specifications, meeting diverse usage needs. The inner wall of the adapter ring has multiple grooves, each engaging with a sliding frame to facilitate the conversion between different lens interfaces. The spacing and width of the grooves are precisely calculated to ensure that the conversion between different lens interfaces does not interfere with each other. The end face of the adapter ring has markings to indicate the location of different lens interfaces, making it convenient for users to select the appropriate interface for installation. Furthermore, the adapter ring is made of high-strength aluminum alloy, possessing excellent mechanical properties and corrosion resistance, maintaining stable physical characteristics during long-term use.
[0012] The technical advantages of this invention are reflected in the following aspects: First, the combined design of the toggle block, slide rail, slide frame, locking block, and spring enables rapid locking and unlocking of the lens interface, significantly improving operational efficiency. Specifically, the operating force of the toggle block is transmitted to the slide frame through a raised structure. The slide frame moves along the slide rail and drives the locking block to complete the locking or unlocking action. The entire process requires no tool assistance, making operation simple and quick. Second, the design of the slot and locking groove ensures the stability of the interface during use, preventing loosening or detachment. The shape of the slot and locking groove perfectly matches the locking block, and the inner surface is hardened, providing high wear resistance and impact resistance, maintaining stable mechanical performance over long-term use. Third, the modular design allows components such as the base, barrel, lens, and adapter ring to be manufactured and maintained independently, reducing production costs and maintenance difficulty. Finally, the adapter ring design is compatible with various lens interfaces of different specifications, meeting diverse usage needs and expanding the product's applicability.
[0013] In summary, this utility model, through its innovative structural design, solves the problem of inconvenient disassembly and assembly in existing lens interface conversion components, demonstrating significant technological advancement and practical value. This utility model not only improves the ease of operation of lens interface conversion components but also enhances their connection stability and maintenance convenience, providing important technical support for related fields.

[0022] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.
[0023] This utility model provides a detachable bullet camera lens interface conversion component, combined with the attached... Figure 1 To be continued Figure 5 The implementation method is explained in detail. Please refer to the appendix. Figure 1 This is a schematic diagram of the overall structure of an embodiment of the present utility model. The component includes a base 1, a cylinder 2, a lens 3, a mounting ring 4, a conversion ring 51, a lever 53, a sliding frame 55, a locking block 56, and a spring 57. Each component is precisely designed to achieve the functions of quick assembly and disassembly and stable connection.
[0024] First, the structure and function of the base 1 are described. As the foundation of the entire assembly, the base 1 supports other components and ensures the stability of the overall structure. (See attached diagram) Figure 1 As shown, the bottom of the base 1 has multiple mounting holes, which are used to fix the base 1 to external equipment with bolts, thereby preventing displacement or shaking during use. The upper surface of the base 1 is precision machined to form a flat surface for mounting the cylinder 2. This design not only improves the load-bearing capacity of the base 1, but also facilitates the subsequent assembly and adjustment of the cylinder 2.
[0025] Next, we will discuss the structure and function of the barrel 2. Barrel 2 is mounted on the base 1, and its interior forms a cylindrical cavity to house the core mechanism of the lens interface conversion assembly. (See attached image) Figure 3 This is a cross-sectional view along the AA direction, clearly showing that the inner surface of the cylinder 2 is precision-machined to form a smooth cylindrical cavity, ensuring stable operation of the internal components. The outer surface of the cylinder 2 has a threaded structure that mates with the mounting ring 4 to fix and adjust the lens position. Furthermore, the front end of the cylinder 2 has a locating pin that engages with the interface end of the lens 3, ensuring that the lens 3 does not rotate or deviate from its intended position during installation.
[0026] The mounting and securing method of lens 3 is one of the key design features of this component. (See attached image.) Figure 5 As shown in the partial disassembly diagram, lens 3 achieves precise positioning by engaging with the positioning pin at the front end of the barrel 2 via its interface end. The interface end of lens 3 has a groove that perfectly matches the positioning pin of barrel 2, thus preventing lens 3 from loosening or shifting during use. Lens 3 also has an anti-slip coating on its exterior, facilitating the application of force during disassembly. This design not only improves the installation accuracy of lens 3 but also enhances its ease of use.
[0027] The design of mounting ring 4 further enhances the flexibility and stability of the components. (See attached image) Figure 1 As shown, the mounting ring 4 is located on the outside of the cylinder 2, and it has a slot 41 and a groove 42 for engaging with corresponding components on the conversion ring 51. The shapes of the slot 41 and groove 42 are precisely calculated to perfectly match the shape of the locking block 56, ensuring that the locking block 56 can be securely locked after entering the groove 42. The inner surfaces of the slot 41 and groove 42 are hardened, providing high wear resistance and impact resistance, and maintaining stable mechanical properties during long-term use. In addition, the edges of the slot 41 and groove 42 are chamfered to guide the locking block 56 smoothly into the groove 42, reducing the frictional resistance between the locking block 56 and the groove 42.
[0028] The adapter ring 51 is one of the core components of this assembly, and its design enables rapid conversion between lens mounts of different specifications. (See attached image) Figure 3As shown, the conversion ring 51 is located inside the cylinder 2, and its inner wall has multiple sliding grooves 52. Each sliding groove 52 cooperates with a sliding frame 55 to achieve the conversion of different lens interfaces. The spacing and width of the sliding grooves 52 are precisely calculated to ensure that the conversion of different lens interfaces does not interfere with each other. The end face of the conversion ring 51 has markings to indicate the position of different lens interfaces, making it convenient for users to select the appropriate interface for installation. The conversion ring 51 is made of high-strength aluminum alloy, which has good mechanical properties and corrosion resistance, and can maintain stable physical properties during long-term use.
[0029] The design of the dial 53 embodies the concept of user-friendly operation. (See attached image) Figure 4 As shown, the toggle block 53 is located on the outer surface of the conversion ring 51. Its shape is ergonomically optimized, featuring a curved surface that conforms to the palm of the hand, facilitating the application of force by the user. The bottom surface of the toggle block 53 fits tightly against the outer surface of the conversion ring 51 and is fixed to the conversion ring 51 with screws, ensuring that the toggle block 53 will not loosen or shift during operation. The inner side of the toggle block 53 has a raised structure that contacts the end of the slide frame 55, transmitting the user's operating force to the slide frame 55. When the user moves the toggle block 53, the raised structure pushes the slide frame 55 along the slide groove 52, thereby causing the locking block 56 to complete the locking or unlocking action. The surface of the toggle block 53 is treated with an anti-slip coating to increase friction during user operation and prevent slippage leading to operational errors.
[0030] The design of the sliding frame 55 and the sliding groove 52 ensures that the movement path of the locking block 56 is precise and controllable. (See attached image) Figure 3 As shown, the inner surface of the slide groove 52 is precision machined to form a smooth track with a certain degree of frictional resistance, ensuring that the movement of the slide frame 55 within the slide groove 52 is both smooth and controllable. The external dimensions of the slide frame 55 match those of the slide groove 52, and it is manufactured using high-precision machining processes to ensure the positioning accuracy of the slide frame 55 within the slide groove 52. A guide structure is provided at the end of the slide frame 55 to guide its movement along the predetermined trajectory of the slide groove 52, preventing the slide frame 55 from deviating from the track. Furthermore, limiting devices are provided at both ends of the slide groove 52 to limit the maximum range of movement of the slide frame 55, preventing the slide frame 55 from detaching from the slide groove 52 due to excessive movement.
[0031] Link 54 transmits the movement of slide frame 55 to locking block 56, ensuring that locking block 56 can accurately enter or exit slot 42. (See attached...) Figure 3As shown, one end of the connecting rod 54 is hinged to the slide frame 55, and the other end is hinged to the locking block 56, forming a linkage mechanism. When the slide frame 55 moves along the slide groove 52, the connecting rod 54 drives the locking block 56 to move synchronously, causing the locking block 56 to extend or retract from the locking groove 42. The length and angle of the connecting rod 54 are precisely calculated to ensure that the movement path of the locking block 56 perfectly matches the position of the locking groove 42. The connecting rod 54 is made of high-strength metal material, which has good tensile strength and bending resistance, and can maintain stable mechanical properties during long-term use. In addition, the hinge point of the connecting rod 54 is equipped with a lubrication device to reduce frictional resistance during movement and improve the service life of the connecting rod 54.
[0032] Spring 57 is installed inside slide frame 55, providing elastic restoring force so that latch 56 remains locked when no external force is applied. (See attached image) Figure 3 As shown, one end of the spring 57 is fixed to the bottom of the slide frame 55, and the other end contacts the top of the slide frame 55, forming a compressed state. When the slide frame 55 moves along the slide groove 52, the spring 57 is further compressed, storing elastic potential energy. When the external force is removed, the spring 57 releases the stored elastic potential energy, pushing the slide frame 55 to reset, thereby causing the locking block 56 to re-enter the locking slot 42. The elastic coefficient of the spring 57 is precisely calculated to ensure that the elastic force it provides meets the locking requirements of the locking block 56 without causing excessive resistance to the movement of the slide frame 55. The spring 57 is made of alloy steel with excellent fatigue resistance, which can maintain stable elastic characteristics during repeated compression and release.
[0033] Describe the operation process of this component in a practical application scenario. S1: The user first installs the lens 3 onto the front end of the barrel 2, achieving precise positioning through the engagement of the groove at the interface end of the lens 3 with the positioning pin at the front end of the barrel 2. S2: Subsequently, the user tightens the mounting ring 4 onto the external thread of the barrel 2, ensuring that the slot 41 and groove 42 of the mounting ring 4 are aligned with the corresponding components on the conversion ring 51. S3: Next, the user moves the lever 53. The protruding structure of the lever 53 pushes the sliding frame 55 along the slide groove 52. The sliding frame 55, through the connecting rod 54, drives the locking block 56 to move synchronously, causing the locking block 56 to extend from the groove 42, completing the locking action. S4: When it is necessary to replace the lens 3, the user moves the lever 53 again. The lever 53 pushes the sliding frame 55 to move in the opposite direction along the slide groove 52. The sliding frame 55, through the connecting rod 54, drives the locking block 56 out of the groove 42, releasing the locked state. S5: Finally, the user loosens the mounting ring 4, removes the lens 3, and completes the disassembly process.
[0034] The above description of the embodiments fully demonstrates the technical effects of this utility model. Through the combined design of the toggle block 53, slide groove 52, slide frame 55, locking block 56, and spring 57, rapid locking and unlocking of the lens interface is achieved, significantly improving operational efficiency. The design of the slot 41 and the locking groove 42 ensures the stability of the interface during use, preventing loosening or detachment. The modular design allows components such as the base 1, barrel 2, lens 3, and adapter ring 51 to be manufactured and maintained independently, reducing production costs and maintenance difficulty. The adapter ring 51 is compatible with various lens interfaces of different specifications, meeting diverse usage needs and expanding the product's applicability.
