Description

Technical Field

[0001] This utility model relates to the field of monitoring equipment technology, and in particular to a rainproof and dustproof housing for road monitoring equipment. Background Technology

[0002] With the acceleration of urbanization and the continuous growth of social security needs, road monitoring equipment plays an indispensable role in traffic management and public safety. Like the "eyes" of the city, they constantly monitor the traffic, providing crucial information for the timely detection of accidents, violations, and the maintenance of urban order.

[0003] These road monitoring devices have become one of the important pieces of equipment in modern life and production. However, most of these monitoring devices are installed in outdoor environments, which can easily shorten their lifespan due to wind and rain. Therefore, protective covers need to be installed to protect the monitoring devices during installation.

[0004] To reduce costs, some housings use ordinary plastic. While this material offers some lightweightness, its waterproof performance is poor. Prolonged exposure to rain causes the plastic to age and deform, widening even the smallest gaps, allowing rainwater to easily penetrate. Furthermore, the smooth surface of ordinary plastic has low dust adhesion; dust easily accumulates on the surface when blown by the wind and then enters the device through gaps. In addition, there are several common problems with the structural design of the housing. Some housings use simple snap-fit ​​connections, which are prone to loosening under daily vibration or slight external force, significantly compromising the seal. Therefore, to address these issues, a rainproof and dustproof housing for road monitoring equipment is proposed. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a rainproof and dustproof housing for road monitoring equipment, aiming to improve the problems of poor waterproof and dustproof performance and easy gap formation caused by external vibration in the existing housing.

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

[0007] A rainproof and dustproof housing for road monitoring equipment includes a protective shell. A sealing strip is provided in the middle of the protective shell. A rotating cover is rotatably connected to the rear side of the protective shell. Two locking blocks are fixedly connected to the front outer side of the rotating cover. An expansion cover is fixedly connected to the top of the rotating cover. A water-blocking strip is fixedly connected to the top of the expansion cover. Guide strips are fixedly connected to the bottom ends of the front and rear sides of the expansion cover. Two lever fixing blocks are rotatably connected to the front side of the protective shell. A threaded U-shaped locking rod is continuously connected to the middle of the lever fixing blocks. A fixing cover is fixedly connected to the middle of the bottom end of the protective shell. A slider is slidably connected inside the fixing cover. A spring is fixedly connected to the top of the slider. A mounting block is fixedly connected to the bottom end of the slider. Two sliding grooves are formed on the outside of the mounting block. An elastic component for supporting the protective shell is provided at the bottom end of the protective shell.

[0008] As a further description of the above technical solution:

[0009] The elastic component includes four positioning blocks. The top ends of the four positioning blocks are fixedly connected to the bottom end of the protective housing. The bottom ends of the positioning blocks are rotatably connected to a damper, and the bottom ends of the damper are rotatably connected to a connecting block.

[0010] As a further description of the above technical solution:

[0011] The top center of the rotating cover has multiple heat dissipation holes, and the bottom of the rotating cover is in contact with the top of the sealing strip.

[0012] As a further description of the above technical solution:

[0013] The outside of the threaded U-shaped clamp is engaged with the outside of the clamp block, and a glass block is fixedly connected to the left side of the protective housing;

[0014] As a further description of the above technical solution:

[0015] The top end of the upright spring is fixedly connected to the top end of the inner wall of the fixed cover;

[0016] As a further description of the above technical solution:

[0017] A sliding roller is fixedly connected to the side of the connecting block near the mounting block, and the outer side of the sliding roller is slidably connected to the inner wall of the sliding groove.

[0018] As a further description of the above technical solution:

[0019] The connecting block is slidably connected to the outside of the mounting block on the side near the sliding roller;

[0020] As a further description of the above technical solution:

[0021] The protective housing has two guide rods fixed inside, and a mounting plate is slidably connected to the outside of the two guide rods. The bottom end of the mounting plate is slidably connected to the bottom end of the inner wall of the protective housing.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, the monitoring equipment is installed inside the protective housing. The rotating cover is closed, and the sealing strip is squeezed and engaged at the opening of the protective housing. The threaded U-shaped clamp is placed on the clamping block, and the lever fixing block is pulled down to lock the threaded U-shaped clamp, thus achieving a sealed and fixed housing. In addition, the outer expansion cover is tilted and fixed on the rotating cover, and the water-blocking strip is fixed to the guide strip at the edge to guide rainwater to flow out along the guide strip. The sealing strip added at the opening of the housing can effectively prevent rainwater and dust from entering the equipment. In addition, the tilted outer expansion cover added at the top, combined with the water-blocking strip at the edge, can guide rainwater to flow along the surface of the housing to the water-blocking strips on both sides and then flow out backward, further reducing the direct impact of rainwater on the equipment.

[0024] 2. In this utility model, the elasticity of the spring reduces the external vibration transmitted through the slider after the shell is installed, and the damper increases the spring's damping ability. Together with the spring pressing against the mounting block, the buffer structure reduces the shaking of the equipment when it is subjected to vibration or external force, maintains the tightness of the shell connection, prevents new gaps from being generated or the original gaps from being widened due to vibration, thereby better maintaining the waterproof and dustproof performance of the equipment, and protecting the electronic components inside the shell.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figures 1 to 3 This utility model provides an embodiment of a rainproof and dustproof housing for road monitoring equipment, comprising a protective housing 1 with a U-shaped opening in the middle to accommodate and protect the monitoring equipment. A sealing strip 2 is provided in the middle of the protective housing 1, fixed at the opening and serving as a key component for sealing the housing. A rotating cover 3 is rotatably connected to the rear of the protective housing 1, with its bottom end contacting the top end of the sealing strip 2. When the rotating cover 3 is closed, the sealing strip 2 is compressed and deformed, filling the gap between the protective housing 1 and the rotating cover 3, effectively preventing rainwater and dust from entering the equipment, ensuring a clean and dry internal environment, and guaranteeing the normal operation of the monitoring equipment.

[0034] Multiple heat dissipation holes 4 are provided at the top center of the rotating cover 3. These holes provide a channel for the heat generated during the operation of the monitoring equipment. While ensuring the outer casing is waterproof and dustproof, this ensures that the internal temperature of the equipment is maintained within the normal operating range, preventing performance degradation or damage due to overheating, and guaranteeing the stable operation and long service life of the monitoring equipment.

[0035] refer to Figure 3 , Figure 4 Two locking blocks 5 are fixedly connected to the front side of the rotating cover 3. The locking blocks 5 are hook-shaped protrusions and are fixed to the left and right ends of the front side of the rotating cover 3. An outer expansion cover 6 is fixedly connected to the top of the rotating cover 3. The outer expansion cover has two functions. First, the outward expansion shape can block sunlight from shining directly on the monitoring equipment, reduce the damage of sunlight to the equipment, and prevent the equipment shell from aging and the internal electronic components from degrading due to high temperature. Second, the inclined fixed design prevents rainwater from flowing towards the camera position and forming a rain curtain.

[0036] A water-blocking strip 7 is fixedly connected to the top of the outer cover 6. The water-blocking strip 7 is fixed to the top and tail of the outer cover 6 and is used to guide rainwater on the outer cover 6 to flow out along the slope of the outer cover 6. Guide strips 8 are fixedly connected to the bottom of the front and rear sides of the outer cover 6 and are used to guide rainwater flowing down the surface of the outer cover 6 to flow out along the guide strips 8 to the tail of the outer cover 6. The guide strips 8 and the water-blocking strip 7 work together to allow rainwater to drain quickly and orderly, reducing the residence time and residual amount of rainwater on the outer shell, minimizing the direct impact and penetration risk of rainwater on the equipment, and ensuring the normal operation of the equipment in rainy weather. Two lever fixing blocks 9 are rotatably connected to the front side of the protective shell 1. Each lever fixing block 9 consists of a T-shaped positioning piece and a triangular tie rod. A threaded U-shaped clamp 10 is continuously connected to the middle of the lever fixing block 9. The two ends of the threaded U-shaped clamp 10 are threaded and fixed to the two sides of the pivot of the lever fixing block 9 by bolts.

[0037] The external part of the threaded U-shaped clamp 10 engages with the external part of the clamp block 5. When the rotating cover 3 is closed, it fits onto the heat dissipation hole 4 and engages with the clamp block 5. Through the leverage action of the lever fixing block 9, the rotating cover 3 and the protective housing 1 are tightly fixed. In addition, the length of the threaded U-shaped clamp 10 can be adjusted by rotating the nut on the threaded U-shaped clamp 10, thereby further strengthening the connection between the sealing strip 2 and the protective housing 1 and enhancing the sealing performance of the housing. The threaded U-shaped clamp 10 is fixedly connected to the left side of the protective housing 1 by rotating it. It is fixed on the left side of the protective housing 1 and provides a transparent protective window for the camera of the monitoring equipment. While ensuring that the camera can capture monitoring images normally, it prevents rainwater, dust, foreign objects and other objects from directly contacting the camera.

[0038] refer to Figure 1 , Figure 5 A fixed cover 11 is fixedly connected to the middle of the bottom end of the protective housing 1. The fixed cover 11 opens downwards, and its inner wall dimensions are designed according to the dimensions of the slider 12 and the upright spring 13, as well as their stroke. The slider 12 is slidably connected inside the fixed cover 11, and the slider 12 is connected to the upright spring 13 and the mounting block 14. The top of the slider 12 is fixedly connected to the upright spring 13, which is fixedly connected to the top of the inner wall of the fixed cover 11. When the slider 12 is subjected to vibration and compression, the upright spring 13 rebounds and vibrates through its own elasticity, releasing the absorbed vibration energy, reducing the vibration amplitude of the equipment, and playing a role in shock absorption and buffering. The bottom end of the slider 12 is fixedly connected to the mounting block 14, and the inner wall of the mounting block 14 slides outside the fixed cover 11. 将设备受到的震动通过滑块12传递给挺立弹簧13进行缓冲处理。 The mounting block 14 has two grooves 15 on its exterior, which are vertically formed on the left and right sides of the mounting block 14.

[0039] The bottom of the protective housing 1 is provided with an elastic component for supporting the protective housing 1, including four positioning blocks 16. The top ends of the four positioning blocks 16 are fixedly connected to the bottom of the protective housing 1, and the positioning blocks 16 are fixed at the four corners of the bottom of the protective housing 1. A damper 17 is rotatably connected to the bottom of the positioning blocks 16, and a connecting block 18 is rotatably connected to the bottom of the damper 17, rotatably connecting the bottom of the positioning blocks 16 and the connecting block 18. A sliding roller 19 is fixedly connected to the side of the connecting block 18 near the mounting block 14. The outer side of the sliding roller 19 is slidably connected to the inner wall of the slide groove 15. When the equipment vibrates, the sliding roller 19 slides within the slide groove 15 as the mounting block 14 moves up and down.

[0040] The connecting block 18 is slidably connected to the outside of the mounting block 14 near the sliding roller 19. The mounting block 14 transmits vibration to the damper 17 through the sliding roller 19 and the connecting block 18, allowing the damper 17 to perform a buffering function. Two guide rods 21 are fixed inside the protective housing 1. A mounting plate 22 is slidably connected to the outside of the two guide rods 21. The bottom end of the mounting plate 22 is slidably connected to the bottom end of the inner wall of the protective housing 1. When installing the monitoring equipment, it is ensured that the mounting plate 22 can only slide smoothly along the axial direction of the guide rods 21, allowing the monitoring camera to accurately align with the glass block 20 and ensuring the accuracy of the monitoring angle.

[0041] Working Principle: When installing the monitoring equipment, first align the equipment with the glass block 20 and fix it to the mounting plate 22 using mounting screws. Then, slide the mounting plate 22 to ensure the monitoring camera fits snugly against the glass block 20. Next, close the rotating cover 3 and lock it onto the protective housing 1. Then, place the threaded U-shaped lever 10 onto the heat dissipation hole 4 and pry the lever fixing block 9. By adjusting the angle between the lever fixing block 9 and the threaded U-shaped lever 10, the lever can be moved away, and the rotating cover 3 can be securely closed onto the protective housing 1. Finally, rotate the nut on the threaded U-shaped lever 10 to further strengthen the connection between the sealing strip 2 and the protective housing 1, causing the rotating cover 3 to press against the sealing strip 2 of the protective housing 1, thereby improving the sealing performance between the protective housing 1 and the rotating cover 3, achieving a dustproof and waterproof effect.

[0042] In addition, an outer cover 6 is obliquely connected to the top of the rotating cover 3 of the protective shell. The outer cover 6 is located outside the protective shell 1, blocking sunlight and providing waterproofing. A water-blocking strip 7 is fixed to the rear of the outer cover 6 away from the camera to guide rainwater on the outer cover 6 out along the slope. Simultaneously, guide strips 8 are fixed to both sides of the outer cover 6 to guide rainwater on its surface out along the guide strips 8 to the rear of the outer cover 6, reducing rainwater residue and direct impact on the equipment. A U-shaped block with an oblique slope is provided at the connection between the outer cover 6 and the rotating cover 3, and a heat dissipation hole 4 is opened in the middle of the rotating cover 3 for heat dissipation of the equipment. This design achieves both waterproof and dustproof functions while ensuring normal heat dissipation of the equipment.

[0043] When the equipment is subjected to vibration or external force, the installed mounting block 14 transmits the vibration and drives the slider 12 to slide within the fixed cover 11, thereby compressing the upright spring 13 and causing it to contract. The upright spring 13 then rebounds this vibration through its own elasticity. Furthermore, when the mounting block 14 slides upward, it drives the sliding roller 19 to slide within the groove 15 and abuts against the damper 17 via the connecting block 18. The damper 17, like the upright spring 13, also rebounds the vibration transmitted by the mounting block 14 through its own elasticity, thus achieving a shock absorption effect. This prevents new gaps from being created due to vibration or the widening of existing gaps, thereby better maintaining the equipment's waterproof and dustproof performance.

[0044] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
