Description

Technical Field

[0001] This invention relates to the field of equipment protection devices, specifically to a fixed monitoring equipment protection device and its installation method. Background Technology

[0002] Fixed monitoring equipment is widely used in outdoor scenarios such as roads, parks, factories, and security checkpoints. It is the core hardware for video surveillance and security. Its working environment often faces external forces such as wind and sand impact, foreign object collision, vehicle scratches, and vibration and impact under extreme weather conditions. Some installation points are also subject to risks such as human damage and environmental corrosion. Therefore, high requirements are placed on the protective structure of monitoring equipment.

[0003] In existing technologies, the protection methods for fixed monitoring equipment are mostly simple external enclosures. For outdoor bullet cameras, the protective housing is mostly bolted on, requiring specialized tools for on-site assembly, disassembly, and maintenance. This is cumbersome, time-consuming, and labor-intensive, especially for monitoring equipment in high-altitude or remote outdoor locations, resulting in low maintenance efficiency. At the same time, the protective structure lacks targeted buffering and stress-relief design. In harsh environments, such as hail or sandstorms, when the housing is impacted, the impact force is directly transmitted to the camera body, which can easily cause camera lens breakage, core damage, loose wiring, and other malfunctions, significantly reducing the service life of the equipment. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a fixed monitoring equipment protection device and installation method. By setting an aluminum buffer corrugated pipe at the top and a side-pushing sliding block for gap buffering structure, setting a buffer corrugated strip structure between the protective seat and the protective shell, and adding a flexible locking structure for the hard rubber fixing seat, the problem of rigid installation of the protective structure, lack of buffering and stress relief design, and low maintenance efficiency is solved.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a camera and a lens cover fixedly mounted on the upper surface of the camera. A buffer fixing device is fixedly mounted at one end of the upper surface of the lens cover, and a hard rubber fixing seat is fixedly mounted on the other end of the lens cover. The buffer fixing device includes symmetrically arranged fixing seats and a side-push sliding block slidably mounted inside the fixing seats. An aluminum buffer corrugated tube is fixedly connected to one side surface of the side-push sliding block inside the fixing seats. The other end of the aluminum buffer corrugated tube is fixedly connected to the fixing seats, and the aluminum buffer corrugated tube is used for buffering the sliding impact of the side-push sliding block. A connecting rod is rotatably connected to the side-push sliding block, and a buckle plate is rotatably connected to the other end of the connecting rod.

[0006] Preferably, the mounting base is fixedly installed on the lens protective cover by bolts, and a fixing member is provided between the two side-push sliding blocks on the upper surface of the mounting base; a snap-locking member is provided on both sides of the upper surface of the fixing member, a sliding pin is provided through the surface of the snap-locking member, and a return spring is fixedly installed on one side of the snap-locking member.

[0007] Preferably, the upper surface of the fixing member is provided with a sliding groove, the sliding pin is slidably installed inside the sliding groove, and the other end of the reset spring is fixedly connected to the fixing member.

[0008] Preferably, the fixing base is perpendicular to the fixing member; a push rod is slidably installed on the upper surface of the lens protective cover, one end of the push rod is tapered and can be inserted into one side of the buckle locking member.

[0009] Preferably, a sliding fastener is provided between the two locking fasteners, and the sliding fastener is slidably installed inside the fastener plate.

[0010] Preferably, a tension spring is fixedly connected to the end of the sliding buckle away from the buckle locking member, and a fixing knob is fixedly connected to the end of the tension spring away from the sliding buckle, and the fixing knob is slidably mounted on the buckle plate.

[0011] Preferably, a protective base is provided below the camera. The protective base is a grid-type protective shell. Sliding strips are fixedly installed on both sides of the protective base by screws, and buffer corrugated strips are fixedly installed on the sliding strips.

[0012] Preferably, the sliding strip, together with the buffer corrugated strip, is slidably installed inside the grooves opened on both sides of the protective housing, the bottom end of the sliding strip is attached to the bottom end of the groove, and the gap in the groove is greater than the total thickness of the buffer corrugated strip and the sliding strip.

[0013] Preferably, a snap-fit ​​post is fixedly installed at one lower end of the protective housing, and the snap-fit ​​post is snapped onto the rigid rubber fixing base. A through groove is opened at the end of the protective housing away from the snap-fit ​​post, and a fixing slot is opened below the through groove at the lower part of the protective housing.

[0014] A method for installing a protective device for fixed monitoring equipment includes the following steps: S1: Fix the camera inside the grille-type protective base, align the sliding grooves on both sides of the protective housing with the sliding clips on both sides of the protective base and push them horizontally so that the sliding clips slide against the bottom of the sliding grooves until the buckle post at one end of the lower surface of the protective housing is fully engaged and locked onto the hard rubber fixing base.

[0015] S2: Press the fixing knob downward through the through groove of the protective shell, and the sliding buckle will push the buckle locking part to slide along the sliding groove of the fixing part to both sides, so that the sliding buckle and the buckle locking part can complete a precise buckle engagement.

[0016] S3: Pull the fixing knob upwards to move the buckle plate upwards via the tension spring, so that the buckle plate is fully engaged in the fixing slot at the bottom of the protective housing; rotate the fixing knob to lock it onto the upper surface of the protective housing, and lock the tension of the tension spring to complete the fixing.

[0017] S4: Push the rod from one side, and apply a pushing force to the buckle locking part at its tapered end. The buckle locking part slides to both sides of the fixing part, directly pushing open the buckle that engages with the inverted protrusion structure of the sliding buckle, causing the tension spring to lose its elastic tension. Rotate the fixing knob in the opposite direction to disengage it from the fixing slot, completing the separation of the protective shell from the camera body and completing the disassembly.

[0018] Compared with the prior art, the present invention provides a fixed monitoring equipment protection device and installation method, which has the following beneficial effects: 1. The camera is fully covered by a gap buffer structure with an aluminum buffer corrugated tube at the top and a side sliding block, a buffer corrugated strip buffer structure between the protective base and the protective shell, and a flexible snap-fit ​​buffer connection of the hard plastic fixing base to avoid impact. This ensures that there are no blind spots in the protection and avoids malfunctions such as broken camera lens, damaged core, and loose wiring.

[0019] 2. The protective housing is initially positioned by horizontal pushing through the sliding groove and sliding strip, and by one-click engagement of the buckle post and hard rubber fixing seat. Then, the overall locking is achieved by operating the fixing knob through the through groove, which greatly improves the efficiency of on-site assembly and maintenance.

[0020] 3. The buffer fixing device is a pre-assembled component. When unlocking, pushing the push rod can realize the full structure linkage reset. All components automatically return to their positions under the action of spring elastic force, without jamming and without the need for manual adjustment. Attached Figure Description

[0023] 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. Example

[0024] Please see Figure 1 - Figure 9This embodiment provides a fixed monitoring equipment protection device, including a camera 3 and a lens cover 2 fixedly mounted on the upper surface of the camera 3. A buffer fixing device 5 is fixedly mounted at one end of the upper surface of the lens cover 2, and a hard rubber fixing seat 9 is fixedly mounted at the other end of the lens cover 2. The buffer fixing device 5 includes symmetrically arranged fixing seats 12 and a side-push sliding block 17 slidably mounted inside the fixing seats 12. An aluminum buffer bellows 16 is fixedly connected to one side surface of the side-push sliding block 17 inside the fixing seats 12. The other end of the aluminum buffer bellows 16 is fixedly connected to the fixing seats 12, and the aluminum buffer bellows 16 is used for buffering the sliding impact of the side-push sliding block 17. A connecting rod 15 is rotatably connected to the side-push sliding block 17. The other end of the rod 15 is rotatably connected to a buckle plate 11; a protective seat 4 is provided below the camera 3. The protective seat 4 is a grid-type protective shell. Sliding strips 7 are fixedly installed on both sides of the protective seat 4 by screws. Buffer corrugated strips 6 are fixedly installed on the sliding strips 7; the sliding strips 7 and the buffer corrugated strips 6 are slidably installed inside the sliding grooves 10 opened on both sides of the protective shell 1. The bottom end of the sliding strip 7 is attached to the bottom end of the sliding groove 10, and the space gap of the sliding groove 10 is greater than the total thickness of the buffer corrugated strips 6 and the sliding strips 7; a buckle post 8 is fixedly installed at one end of the lower part of the protective shell 1. The buckle post 8 is buckled and installed on the hard rubber fixing seat 9. A through groove 24 is opened at the end of the protective shell 1 away from the buckle post 8. A fixing groove 25 is opened below the through groove 24 located below the protective shell 1.

[0025] Thus, the protective base 4 is fixedly installed on the camera 3 mounting bracket, and the camera 3 is fixedly installed inside the protective base 4, maintaining an installation gap with the protective base 4. The upper end of the lens protective cover 2 is fixedly installed on the hard plastic mounting base 9 and the buffer fixing device 5. The sliding grooves 10 opened on both sides of the protective housing 1 are aligned with the sliding strips 7 on both sides of the protective base 4 and pushed laterally until the buckle post 8 at one end of the protective housing 1 is fully snapped into the hard plastic mounting base 9. On the buffer fixing device 5, the side push sliding block 17 is slidably installed at the slide rails at both ends inside the mounting base 12. Aluminum buffer corrugated tubes 16 are fixed at both ends of the mounting base 12 and on the outside of the side push sliding block 17, with a sliding buffer gap reserved between the aluminum buffer corrugated tube 16 and the side push sliding block 17. One end of the connecting rod 15 is rotatably connected to the side push sliding block 17, and the other end is rotatably connected to the buckle plate 11, completing the assembly of the buffer linkage structure. The protective housing 1 firstly provides natural protection for the camera 3, preventing corrosion caused by wind and sun, and enhancing its service life. Secondly, it provides external force protection. When the outer shell 1 is impacted by an external force, the buffer corrugated strips 6 on both sides of the protective seat 4 are compressed and undergo elastic deformation, absorbing most of the vibration and impact force. The gap reserved between the slide groove 10 and the sliding clip 7 provides space for the deformation of the buffer corrugated strips 6. The sliding clip 7 fits against the bottom of the slide groove 10, completely restricting the excessive displacement of the component, further dissipating the impact force transmitted to the camera 3. When the stress is greater than the bearing capacity of the buffer corrugated strips 6, the buckle plate 11 moves downward under the force, and then drives the side push sliding block 17 to slide outward through the connecting rod 15. The side push sliding block 17 then presses against the aluminum buffer corrugated tube 16, causing it to undergo elastic deformation to absorb the impact force. The sliding buffer gap between the two avoids hard contact impact, completely blocking the transmission of impact force to the lens cover 2 and the camera 3. When the residual slight vibration is transmitted to the connection between the protective shell 1 and the lens cover 2, the locking structure of the hard rubber fixing seat 9 and the buckle post 8 undergoes slight elastic deformation, absorbing the residual impact force, completing the buffering and unloading of the entire structure, and achieving all-round protection for the camera 3.

[0026] The mounting base 12 is fixedly mounted on the lens protective cover 2 by bolts. A fixing member 20 is provided on the upper surface of the mounting base 12 between the two side-push sliding blocks 17. A latching locking member 21 is provided on both sides of the upper surface of the fixing member 20. A sliding pin 23 is provided through the surface of the latching locking member 21. A return spring 22 is fixedly mounted on one side of the latching locking member 21. A sliding groove is formed on the upper surface of the fixing member 20. The sliding pin 23 is slidably mounted inside the sliding groove. The other end of the return spring 22 is fixedly connected to the fixing member 20. The mounting base 12 and... The fixing member 20 is vertical; a push rod 13 is slidably installed on the upper surface of the lens protective cover 2. One end of the push rod 13 is tapered and can be inserted into one side of the buckle locking member 21; a sliding buckle member 19 is buckled between the two buckle locking members 21 and is slidably installed inside the buckle plate 11; a tension spring 18 is fixedly connected to the end of the sliding buckle member 19 away from the buckle locking member 21, and a fixing knob 14 is fixedly connected to the end of the tension spring 18 away from the sliding buckle member 19. The fixing knob 14 is slidably installed on the buckle plate 11. Thus, by pressing the fixing knob 14 downward through the through groove 24 on the upper surface of the protective housing 1, the fixing knob 14 pushes the tension spring 18 to move downward simultaneously. The tension spring 18 drives the sliding buckle 19 to slide downward along the buckle plate 11. The bottom end of the inverted protrusion structure of the sliding buckle 19 pushes the buckle locking member 21 to slide towards both sides of the fixing member 20, so that the buckle structure and the inverted protrusion structure of the sliding buckle 19 interlock, completing the locking and fixing of the two. Pulling the fixing knob 14 upward, the fixing knob 14 drives the buckle plate 11 to move upward through the tension spring 18. The buckle plate 11 is slid upward to the fixed slot 25, thus positioning the buckle plate 11 with the fixed slot 25. At this time, the tension spring 18 is stretched, generating a continuous tension force. The fixing knob 14 is rotated to make it fit against the upper surface of the protective shell 1, thereby completing the overall fixation. At this time, the components form a rigid locking closed loop. The fixing knob 14 is locked to the upper surface of the shell. The tension spring 18 is tensioned to fix the sliding buckle 19. The sliding buckle 19 engages with the buckle locking member 21. The buckle locking member 21 is limited to the fixing member 20. The buckle plate 11 is inserted into the fixed slot 25. Once the protective device is fully locked and in working condition, manually push the rod 13 inside the fixed base 12. Its tapered end applies a lateral thrust to the buckle locking member 21, pushing the buckle locking member 21 to slide slightly to both sides of the fixed member 20. This directly opens the buckle engagement with the inverted protrusion structure of the sliding buckle member 19, causing the tension spring 18 to lose its elastic tension. Rotate the fixing knob 14 in the opposite direction to disengage it from the fixing slot 25, releasing the buckle plate 11 from the locking slot 25. The protective housing 1 can then be pulled directly upwards to separate from the camera 3 body, completing the disassembly and facilitating replacement.

[0027] The working principle of the above embodiment is as follows: The camera 3 is fixedly installed inside the grille-type protective base 4, maintaining the installation gap between the two. The sliding grooves 10 on both sides of the protective housing 1 are aligned with the sliding clips 7 on both sides of the protective base 4 and pushed laterally, so that the sliding clips 7 slide against the bottom end of the sliding groove 10 until the buckle post 8 of the protective housing 1 is completely snapped into the hard plastic fixing base 9, completing the initial positioning of the housing. The fixing knob 14 is pressed down through the through groove 24 of the protective housing 1, and the sliding buckle 19 is driven to slide down through the tension spring 18. The sliding buckle 19 pushes the buckle locking member 21 to slide along the sliding groove of the fixing member 20 to both sides, compressing the return spring 22, so that the sliding buckle 19 and the locking member 21 slide together. The snap-locking component 21 completes a precise snap-locking engagement; pulling the fixing knob 14 upwards causes the snap-locking plate 11 to move upwards via the tension spring 18, so that the snap-locking plate 11 is fully engaged in the fixing groove 25 of the protective housing 1; rotating the fixing knob 14 causes it to snap onto the upper surface of the protective housing 1, locking the tension spring 18 in its tensioned state; at this time, the push rod 13 is not under force, and the tapered end is still in contact with the snap-locking component 21, forming a closed loop with all locking structures, and the entire protective device is installed. When the protective housing 1 is impacted by an external force, the buffer corrugated strips 6 on both sides of the protective seat 4 are compressed and undergo elastic deformation, absorbing most of the vibration and impact force, and the gap reserved between the slide groove 10 and the sliding strip 7 is also addressed. This provides space for the deformation of the buffer corrugated strip 6, and the sliding strip 7 fits against the bottom of the slide groove 10, completely limiting excessive displacement of the components, further dissipating the impact force transmitted to the camera 3. When the stress exceeds the bearing capacity of the buffer corrugated strip 6, it moves downward through the buckle plate 11, and then drives the side-push sliding block 17 to slide outward through the connecting rod 15. The side-push sliding block 17 then presses against the aluminum buffer corrugated tube 16, causing it to undergo elastic deformation to absorb the impact force. The sliding buffer gap between the two avoids hard contact impact, completely blocking the transmission of impact force to the lens cover 2 and the camera 3. The residual slight vibration is transmitted to the connection between the protective housing 1 and the lens cover 2, where it hardens. The engagement structure of the fixed seat 9 and the buckle post 8 undergoes slight elastic deformation, absorbing residual impact force and completing the buffering and unloading of the entire structure, thus achieving all-round protection for the camera 3. The manual push rod 13 applies a lateral pushing force to the buckle locking member 21 at its tapered end, pushing the buckle locking member 21 to slide slightly to both sides of the fixed member 20, directly opening the buckle engagement with the inverted protrusion structure of the sliding buckle member 19, causing the tension spring 18 to lose its elastic tension. The reverse rotation of the fixing knob 14 disengages it from the fixing slot 25, releasing the buckle plate 11 from the locking of the fixing slot 25. The protective shell 1 can then be pulled directly to one side to separate from the main body of the camera 3 and complete the disassembly, facilitating the replacement of the protective shell 1.

[0028] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
