Description

Technical Field

[0001] This invention belongs to the field of lens replacement technology, specifically relating to a modular network surveillance lens quick-release replacement mechanism. Background Technology

[0002] As a core component of security monitoring systems, network surveillance cameras are widely used in various scenarios such as buildings, parks, roads, and industrial plants. During long-term use, they are prone to disassembly, replacement, or maintenance due to environmental wear, lens malfunction, or changes in scenario requirements. Currently, the connection structure between surveillance cameras and the camera body mostly uses threaded engagement or bolt fastening designs. While these connection methods offer a certain degree of stability, they have many compatibility defects and can no longer meet the modular and convenient maintenance needs of modern monitoring equipment.

[0003] On the one hand, the disassembly and assembly of traditional connection structures require specialized tools such as wrenches and screwdrivers, making the operation cumbersome. This is especially true for surveillance cameras installed in special scenarios such as high altitudes or confined spaces, where staff must carry tools and climb to work, increasing both the difficulty and time required, and raising safety risks associated with working at heights. On the other hand, threaded connection structures are prone to slippage and jamming after prolonged use due to environmental vibrations and changes in temperature and humidity. Bolted structures are susceptible to bolt corrosion and loosening, making lens disassembly and assembly difficult and potentially affecting the stability of the surveillance image, or even causing the lens to detach and become damaged. Some existing surveillance cameras use an integrated design, with no independent disassembly structure between the lens and the body. When a lens malfunctions, the entire surveillance equipment must be disassembled and replaced, resulting in a significant waste of equipment resources and a substantial increase in maintenance costs. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a modular network monitoring lens quick-release replacement mechanism.

[0005] The technical solution adopted to solve the above technical problems is: a modular network monitoring lens quick-release replacement mechanism, including a lens mounting base, a monitoring lens assembly is provided at one end of the lens mounting base, the monitoring lens assembly is fixedly installed with the lens mounting base; the monitoring lens assembly includes a monitoring lens, a monitoring lens body is provided on one side of the lens mounting base, an extension mounting base is fixedly installed on the side of the monitoring lens body near the lens mounting base, and a lens quick-release assembly is installed between the lens mounting base and the extension mounting base.

[0006] Furthermore, a guide mounting seat is provided at the end of the lens mounting base away from the monitoring lens assembly. The lens mounting base and the guide mounting seat are fixedly installed together. Multiple sets of fixing and mounting grooves are evenly opened on the outer circumference of the guide mounting seat. The lens mounting base and the guide mounting seat are integrated.

[0007] Furthermore, the lens quick-release assembly includes a mounting sleeve that is slidably connected to the fixed mounting slot. A sleeve mounting seat is provided at the end of the mounting sleeve away from the guide mounting seat. The mounting sleeve and the sleeve mounting seat are fixedly installed together and are integrally formed.

[0008] Furthermore, one end of the mounting sleeve has multiple sets of steel ball limiting grooves evenly spaced around the fixed mounting groove. The cross-section of the multiple sets of steel ball limiting grooves is an arc shape that narrows on both sides, and steel balls are engaged in the multiple sets of steel ball limiting grooves.

[0009] Through the above technical solution, the return spring applies continuous pressure to the positioning ring, causing multiple sets of steel balls to be tightly engaged in the fixed mounting groove, forming an elastic self-locking structure. The multiple steel balls are evenly distributed with force along the circumference, resulting in strong load-bearing capacity and effectively resisting loosening caused by long-term vibration. The steel ball limiting groove adopts an arc-shaped structure design that narrows on both sides, forming a precise engagement with the steel balls. This not only provides stable movement limit for the steel balls but also allows the steel balls to achieve surface contact engagement with the fixed mounting groove when locked, improving the firmness of the engagement.

[0010] Furthermore, the sleeve mounting base is symmetrically provided with limiting rails on its outer side, and the limiting rails are fixedly installed with the sleeve mounting base. A connecting sleeve is provided on the outer side of the limiting rails, and the connecting sleeve is symmetrically provided with positioning rail grooves. The positioning rail grooves are slidably connected with the limiting rails. A return spring is sleeved on the outer wall of the mounting sleeve, and a protruding handle ring block is provided on one side of the connecting sleeve. The protruding handle ring block is fixedly connected to the outer wall of the connecting sleeve.

[0011] With the above technical solution, when the steel ball moves to the position of the fixed installation groove on the guide mounting seat, the positioning track groove is released, and the reset spring can push the positioning ring to slide in the direction of the steel ball. The steel ball is engaged in the fixed installation groove through the steel ball limiting groove, thereby completing the rapid fixed installation between the monitoring lens assembly and the monitoring lens body.

[0012] Furthermore, the raised handle ring block and the connecting sleeve are integrally formed, and the outer circumference of the raised handle ring block is uniformly provided with anti-slip texture.

[0013] Through the above technical solution, the anti-slip texture can effectively increase the contact friction between the worker's hand and the surface of the raised handle ring, avoiding slippage caused by sweaty hands, dust and oil stains, or unstable hand force when working at height.

[0014] Furthermore, a positioning ring is provided at the end of the connecting sleeve away from the positioning track groove. The positioning ring is fixedly installed on the inner wall of the connecting sleeve. One end of the return spring is fixedly installed on the sleeve mounting base, and the other end of the return spring is fixedly connected to the positioning ring.

[0015] With the above technical solution, when the positioning ring leaves the outside of the steel ball, it no longer blocks the space where the steel ball can move outward, and the steel ball can move outward. The positioning ring slides towards the steel ball, so that the positioning ring applies pressure to the steel ball, which can lock the space where the steel ball can move outward.

[0016] Furthermore, the sleeve mounting base has a steel ring mounting groove at one end near the steel ball limiting groove, and a limiting steel ring is fixedly installed in the steel ring mounting groove. The limiting steel ring is made of stainless steel.

[0017] Through the above technical solution, the reset spring pushes the positioning ring to apply continuous pressure to the steel ball, so that the steel ball is tightly locked in the fixed mounting groove, forming an elastic locking structure. Without the need for complex tools such as wrenches or screwdrivers, the fixing between the fixed mounting sleeve and the guide mounting seat can be completed by manually pushing the protruding handle ring block, inserting the mounting sleeve, and releasing the reset in three steps. When disassembly is required, the operator pushes the protruding handle ring block towards the sleeve mounting seat again, and the positioning ring moves away from the outside of the steel ball, no longer blocking the space where the steel ball can move outward. Holding the lens mounting seat allows the guide mounting seat to slide out of the mounting sleeve.

[0018] The beneficial effects of the present invention are as follows: (1) The present invention applies continuous pressure to the positioning ring by designing a reset spring, so that multiple sets of steel balls are tightly engaged in the fixed installation groove, forming an elastic self-locking structure. The multiple steel balls are evenly distributed along the circumference and have strong load-bearing capacity, which can effectively resist the loosening caused by long-term vibration. Structurally, it avoids loosening and displacement of the connection, ensures the connection stability between the lens and the body, and at the same time ensures the accuracy of monitoring imaging and extends the overall service life of the equipment. When the steel balls are engaged in the fixed installation groove, a crisp click sound will be made. The staff can confirm the connection status based on the sound. The cooperation between the limit track and the positioning track groove makes the connecting sleeve move smoothly and stably. When inserted, the guide mounting seat is automatically centered, and there is no need for visual alignment. (2) The present invention designs a quick-release lens assembly. The reset spring pushes the positioning ring to apply continuous pressure to the steel balls, so that the steel balls are tightly engaged in the fixed installation groove, forming an elastic locking structure. There is no need for complex tools such as wrenches or screwdrivers. The quick fixed installation between the monitoring lens assembly and the monitoring lens body can be completed by manually pushing the protruding handle ring block, inserting the installation sleeve and releasing the reset in three steps, which greatly improves the installation efficiency. (3) The present invention adopts a modular design, which designs the monitoring lens assembly, the monitoring lens body and the lens quick-release assembly as independent assembly modules. The modules are connected by standardized structure. When any module fails, wears out or the lens specifications need to be upgraded due to scene requirements, only the corresponding module needs to be replaced. There is no need to disassemble and scrap the entire equipment, which greatly reduces the maintenance and upgrade costs of the equipment and improves the reuse rate of parts, which is in line with the design concept of energy saving and environmental protection.

[0021] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0022] like Figures 1-3 As shown, a modular network surveillance camera quick-release replacement mechanism of this embodiment includes a camera mounting base 1, a surveillance camera assembly 11 is provided at one end of the camera mounting base 1, and the surveillance camera assembly 11 is fixedly installed with the camera mounting base 1; the surveillance camera assembly 11 includes a surveillance camera, a surveillance camera body 2 is provided on one side of the camera mounting base 1, an extension mounting base 21 is fixedly installed on the side of the surveillance camera body 2 near the camera mounting base 1, and a camera quick-release assembly 3 is installed between the camera mounting base 1 and the extension mounting base 21; a guide mounting base 12 is provided at the end of the camera mounting base 1 away from the surveillance camera assembly 11, and the camera mounting base 1 and the guide mounting base 12 are fixedly installed together, and multiple sets of fixing mounting grooves 13 are evenly opened on the outer circumference of the guide mounting base 12, and the camera mounting base 1 and the guide mounting base 12 are integrated.

[0023] like Figures 1-4 As shown, the lens quick-release assembly 3 includes a mounting sleeve 30 that is slidably connected to the fixed mounting slot 13. A sleeve mounting seat 31 is provided at the end of the mounting sleeve 30 away from the guide mounting seat 12. The mounting sleeve 30 and the sleeve mounting seat 31 are fixedly installed together, forming an integrated unit. Multiple sets of ball bearing limiting grooves 32 are evenly spaced around the circumference of one end of the mounting sleeve 30, corresponding to the number of fixed mounting slots 13. These ball bearing limiting grooves 32 have a cross-section that narrows at both sides in an arc shape, and are engaged within each other. With steel balls 33, the return spring 34 applies continuous pressure to the positioning ring 39, causing multiple sets of steel balls 33 to be tightly engaged in the fixed mounting groove 13, forming an elastic self-locking structure. The multiple steel balls 33 are evenly distributed along the circumference, with strong load-bearing capacity, which can effectively resist loosening caused by long-term vibration. The steel ball limiting groove 32 adopts an arc-shaped structure design that narrows on both sides, forming a precise engagement with the steel balls 33. It can not only provide stable movement limit for the steel balls 33, but also allow the steel balls 33 to achieve surface contact engagement with the fixed mounting groove 13 when locked, improving the firmness of the engagement.

[0024] like Figures 1-6As shown, a limiting track 35 is symmetrically arranged on the outer side of the sleeve mounting base 31. The limiting track 35 is fixedly installed between the sleeve mounting base 31 and the limiting track 35. A connecting sleeve 38 is arranged on the outer side of the limiting track 35. A positioning track groove 310 is symmetrically opened inside the connecting sleeve 38. The positioning track groove 310 is slidably connected to the limiting track 35. A return spring 34 is sleeved on the outer wall of the mounting sleeve 30. A protruding handle ring block 311 is arranged on one side of the connecting sleeve 38. The protruding handle ring block 311 is fixedly connected to the outer wall of the connecting sleeve 38. When the steel ball 33 moves to the position of the fixed mounting groove 13 on the guide mounting base 12, the positioning track groove 310 is released. The return spring 34 can push the positioning ring 39 to slide in the direction of the steel ball 33. The steel ball 33 is engaged into the fixed mounting groove 13 through the steel ball limiting groove 32, thereby completing the quick fixed installation between the monitoring lens assembly 11 and the monitoring lens body 2.

[0025] like Figures 1-6 As shown, the raised handle ring block 311 and the connecting sleeve 38 are integrally formed. The outer circumference of the raised handle ring block 311 is evenly patterned with anti-slip textures. These textures effectively increase the contact friction between the operator's hand and the surface of the raised handle ring block 311, preventing slippage due to sweaty hands, dust, oil, or unstable hand pressure during operation. A positioning ring 39 is provided at the end of the connecting sleeve 38 away from the positioning track groove 310. The positioning ring 39 is fixedly installed on the inner wall of the connecting sleeve 38. One end of the return spring 34 is fixedly installed on the sleeve mounting base 31, and the other end of the return spring 34 is fixedly connected to the positioning ring 39. When the positioning ring 39 moves away from the outside of the steel ball 33, it no longer blocks the space for the steel ball 33 to move outward, allowing the steel ball 33 to move outward. The positioning ring 39 slides towards the steel ball 33, applying pressure to the steel ball 33 and locking it in place. 33 has an outward-moving space; the sleeve mounting base 31 has a steel ring mounting groove 36 at one end near the steel ball limiting groove 32, and a limiting steel ring 37 is fixedly installed in the steel ring mounting groove 36. The limiting steel ring 37 is made of stainless steel. The return spring 34 pushes the positioning ring 39 to apply continuous pressure to the steel ball 33, so that the steel ball 33 is tightly locked in the fixed mounting groove 36, forming an elastic locking structure. Without the need for complex tools such as wrenches or screwdrivers, the fixing between the fixed mounting sleeve 30 and the guide mounting base 12 can be completed by manually pushing the protruding handle ring block 311, inserting the mounting sleeve 30, and releasing the reset in three steps. When disassembly is required, the operator pushes the protruding handle ring block 311 towards the sleeve mounting base 31 again, and the positioning ring 39 moves away from the outside of the steel ball 33, no longer blocking the space where the steel ball 33 can move outward. Holding the lens fixing base 1 will allow the guide mounting base 12 to slide out from the mounting sleeve 30.

[0026] The working principle of this embodiment is as follows: When the monitoring lens assembly 11 needs to be disassembled and replaced from the monitoring lens body 2, the operator pushes the protruding handle ring block 311 towards the sleeve mounting base 31, so that the protruding handle ring block 311 drives the positioning ring 39 to slide along the direction of the limiting track 35 through the connecting sleeve 38. At this time, the positioning ring 39 leaves the outside of the steel ball 33 and no longer blocks the space where the steel ball 33 can move outward. Further, the guide mounting base 12 is aligned with the outer wall of the mounting sleeve 30 and inserted. When the steel ball 33 moves to the position of the fixed mounting groove 13 on the guide mounting base 12, the positioning track groove 310 is released. The reset spring 34 can push the positioning ring 39 to slide towards the steel ball 33, so that the positioning ring 39 applies a pressure to the steel ball 33. The steel ball 33 is engaged into the fixed mounting groove 13 through the steel ball limiting groove 32, thereby completing the quick fixed installation between the monitoring lens assembly 11 and the monitoring lens body 2. When disassembly is required, the worker pushes the protruding handle ring 311 towards the sleeve mounting base 31 again, and the positioning ring 39 moves away from the outside of the steel ball 33, no longer blocking the space where the steel ball 33 can move outward. Holding the lens fixing base 1 will allow the guide mounting base 12 to slide out of the mounting sleeve 30.

[0027] The above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention.
