[0001] This utility model relates to a dustproof packaging shell, and more particularly to a dustproof packaging shell for a sensor, belonging to the technical field of sensor packaging shells. Background Technology
[0002] Sensors play an important role in production and daily life. There are many types of sensors, each with different functions. When using some sensors, especially in harsh environments such as industrial production and outdoor monitoring, they need to cope with interference from the surrounding environment. Therefore, a dustproof enclosure is installed on the outside of the sensor to prevent dust, impurities and other contaminants from entering the sensor and causing damage to the sensitive elements.
[0003] The main structure of the dustproof enclosure is that two covers are connected by bolts, forming a cavity inside which a sensor can be installed. However, some sensors generate heat during use. Although the dustproof enclosure can prevent dust from entering, it can also prevent the heat inside the cavity from dissipating, leading to heat accumulation and affecting the sensor's performance.
[0004] Therefore, it is urgent to improve the dustproof packaging shell of the sensor to solve the above-mentioned problems. Utility Model Content
[0005] The purpose of this invention is to provide a dustproof enclosure for a sensor. By opening a through slot in the cover and then placing a dustproof mesh inside the slot, the heat generated by the sensor can be transferred from the cavity to the external environment, reducing the accumulation of temperature inside the cavity.

[0027] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.
[0028] like Figures 1-6 As shown, the sensor dustproof enclosure provided in this embodiment includes two covers 1 with mounting slots 2. The two covers 1 are connected by bolts, and the mounting slots 2 on the two covers 1 are joined to form a cavity 3 for mounting the sensor. In specific use, the sensor 100 is installed on one of the covers 1, and then the other cover 1 is connected to the cover 1 by bolts. At this time, the two covers will seal the sensor 100 to protect it from external dust. The specific installation method is an existing technology and will not be described in detail.
[0029] To ensure effective heat dissipation without dust ingress, a through-hole placement groove 4 is provided on the cover 1. A slide rail 5 with an opening at one end is provided on the placement groove 4. A frame 6 with a dustproof mesh 7 slides along the slide rail 5. The method of fixing the dustproof mesh 7 is existing technology and is not limited or described in detail. Multiple dustproof meshes 7 can be used to increase the dustproof effect. The number of dustproof meshes 7 is also not limited. The cover 1 is provided with a buckle assembly for fixing the frame 6 within the slide rail 5. In use, the two covers 1 protect the sensor 100 within the cavity 3. Because the cover 1 has a through-hole placement groove 4, the sensor 100 passes through the placement groove 4. The heat generated during operation will dissipate to the outside from the placement slot 4. To prevent dust from entering the cavity 3 from the placement slot 4, the frame 6 with the dustproof net 7 is slid in along the opening of the slide 5 until the frame 6 is completely inside the slide 5. At this time, the inside and outside of the cavity 3 can only be connected through the dustproof net 7. The dustproof net 7 can prevent external dust from entering without affecting the heat dissipation. When the frame 6 is in the slide 5, the buckle assembly can be used to fix the frame 6 in the slide 5 to prevent the frame 6 from coming off the slide 5. In addition, the buckle assembly also makes it easy to disassemble and assemble the frame 6 and to clean the dustproof net 7 on the frame 6.
[0030] To achieve the above effect, specifically, such as Figures 3-5 As shown, the snap-fit assembly can be set in two sets, symmetrically arranged, to ensure the stability of the frame 6 when snapped in. Whether the snap-fit assembly is set in one or two sets depends on the actual use and is not limited. It includes a sliding plate 8, a pin 9, a pin block 10, and a spring 11. The sliding plate 8 is connected to the mounting groove 2 of the cover 1, the pin 9 is slidably connected to the sliding plate 8, the pin block 10 is connected to the end of the pin 9, and a through groove 12 is provided on the slide rail 5. The outer wall of frame 6 is provided with a snap-fit groove 13 corresponding to the through groove 12. The pin 10 is movably snapped into the snap-fit groove 13 through the through groove 12. The two ends of the spring 11 are respectively connected to the sliding plate 8 and the pin 10. When the frame 6 gradually slides into the slide rail 5, the frame 6 will contact the pin 10. The end of the pin 10 facing the slide rail opening is chamfered. Under the action of the spring 11, the pin 10 will retract under the compression of the frame 6 and finally engage with the snap-fit groove 13 on the frame 6.
[0031] To facilitate the release of the locking relationship between the pin 10 and the locking slot 13, therefore, as Figure 6As shown, the snap-fit assembly also includes a guide member 15 and a guide post 14; the end of the pin 9 away from the pin block 10 passes through the sliding plate 8 and is connected to the guide post 14. The guide member 15 is provided with a guide groove, which is suitable for the guide post 14 to slide. The guide groove includes a first guide groove 16 and a second guide groove 17 that are interconnected. The first guide groove 16 extends along the axial direction of the pin 9, and the second guide groove 17 extends from the first guide groove 16 to the outside of the pin 9 and forms an angle with the axis of the pin 9. When the frame 6 presses the pin block 10, the pin block 10 will move along the axial direction of the pin 9, thereby driving the guide post. Moving within guide groove 16, when the snap-fit groove 13 engages with the pin 10, the guide post will return to its initial position, which is the intersection of guide groove 16 and guide groove 17. When it is necessary to move the pin 10 away from the snap-fit groove 13, simply move the guide member 15 along the radial direction of the pin 9, so that the guide post 14 and guide groove 17 can slide relative to each other. The inclined guide groove 17 will guide the guide post 14 to move along the axial direction of the pin 9, thereby driving the pin 10 to move away from the snap-fit groove 13. At this time, the frame 6 can be removed from the slide rail 5.
[0032] Furthermore, such as Figure 5 As shown, the buckle assembly also includes a push plate 18, a connector 19, and a limiting rail 20; a through sliding groove 21 is provided on the cover 1, the limiting rail 20 is connected to both sides of the sliding groove 21, the push plate 18 is slidably connected to the limiting rail 20, and the side of the push plate 18 facing the inside of the cover 1 is connected to the guide 15 through the connector 19. The push plate 18 is provided to facilitate the manual movement of the guide 15, while the limiting rail 20 provides a limiting and guiding function for the movement of the push plate 18.
[0033] Furthermore, such as Figure 5 As shown, a spring plate 22 is connected to the side of the push plate 18 facing the inside of the cover 1. A second spring 23 is connected to the spring plate 22. One end of the second spring 23 is connected to the inner wall of the mounting groove 2. When the push plate 18 is moved, the second spring 23 will be compressed. When the push plate 18 is released, the second spring 23 will release its elastic force, so that the push plate 18 returns to its initial position for easy reuse.
[0034] Furthermore, such as Figure 6As shown, a spring 24 is connected to the inner wall of the mounting groove 2, and an elastic plate 25 is connected to the end of the spring 24. The end of the slide 5 away from the main body opening is provided with a pushing groove 26 to accommodate the passage of the spring 24 and the elastic plate 25. The elastic plate 25 is in contact with the frame 6. When the frame 6 is engaged in the slide 5, one end of the frame 6 will squeeze the elastic plate 25, which will in turn squeeze the spring 24. When the engagement between the pin 10 and the engagement groove 13 is released, the spring 24 releases its elastic force and pushes the frame 6 to slide in the slide 5 through the elastic plate 25, thereby making it easy to remove the frame 6 from the slide 5.
[0035] like Figure 1 As shown, several heat dissipation fins 27 are provided on the outer side walls of both covers 1 to further enhance the heat dissipation effect of the covers 1.
[0036] like Figure 3 As shown, a sealing plate 28 is bolted to the frame 6, which facilitates the sealing of the frame when the dustproof net 7 is not in use, thereby putting the cover 1 back into a sealed state.
