Description

Technical Field

[0001] This invention belongs to the field of monitoring terminal housing technology, and specifically relates to a modular monitoring terminal housing structure with IP66 protection rating. Background Technology

[0002] The existing IP66 protection rating refers to dust and water protection. Dust cannot enter the equipment and is completely prevented from contact. It can withstand strong spray from any direction (12.5mm nozzle, water flow rate of 100L / min, distance of 3 meters, time of at least 3 minutes) without affecting the function of the equipment.

[0003] A search revealed that Chinese Patent Publication No. CN214410795U, authorized on October 15, 2021, discloses a monitoring terminal housing and a monitoring terminal. The housing includes: a shell divided into a first cavity and a second cavity that are isolated from each other; the first cavity is used to install a core controller and a positioning module; the second cavity is used to install sensors and is connected to the external environment; a first connection port is located on the side wall of the first cavity; a second connection port is located between the first cavity and the second cavity; the first connection port is used for connecting the core controller to an underground displacement gauge and for connecting the positioning module to an antenna; the second connection port is used to connect the core controller and the sensors. By setting up the isolated first and second cavities and using the second cavity, which is connected to the external environment, to house the sensors, the detection requirements of the sensors can be guaranteed. Using the first cavity to install the core controller and the positioning module can reduce the impact of the external environment on these components, thereby improving the lifespan and environmental adaptability of the monitoring terminal to a certain extent.

[0004] However, the device still has the following defects: Although it can improve the lifespan and environmental adaptability of the monitoring terminal to a certain extent, the monitoring terminal shell cannot adjust the sealing effect of open structures such as the connection port and air intake grille during the process of simulating harsh environments and testing the IP66 protection level, which makes it unusable during the IP66 protection level test. Summary of the Invention

[0005] To address the aforementioned issues, this invention provides a modular monitoring terminal housing structure with an IP66 protection rating, comprising a housing assembly. A first sealing component for dust and water protection of the air intake grille and connection port is slidably connected to the outer wall of the housing assembly. A second sealing component for dust and water protection of the cavity is provided at the bottom of the housing assembly. Long bolts are threadedly connected to the corners of the second and first sealing components. A sealing cover plate for dust and water protection of the cavity is provided at the top of the housing assembly. Internally threaded cylinders are penetratingly connected to the corners of the sealing cover plate and the housing assembly. A nut is provided at one end of the internally threaded cylinder, and the other end of the internally threaded cylinder is threadedly connected to the long bolts.

[0006] Furthermore, the outer casing assembly includes an outer casing body; the top of the outer casing body has a first cavity, and the top of the first cavity is fitted and connected to a sealing cover plate; the outer wall of the outer casing body has mounting grooves near the corners, and the inner wall of the mounting groove is fixedly connected to a limit ring base.

[0007] Furthermore, a through hole is provided at the bottom corner of the outer casing, and the through hole is connected to the mounting groove. A side recessed groove is also provided on the outer wall of the outer casing, and the side recessed groove is located at the bottom of the mounting groove.

[0008] Furthermore, the top of the side recess is provided with an upper limit layer, and the bottom of the side recess is provided with a lower limit layer. A first connection port is embedded in one side wall of the side recess. A second cavity is opened on the bottom of the outer shell and on the side away from the first connection port. An air intake grille communicating with the second cavity is opened on the outer wall of the outer shell. A lower recess is also opened on the bottom of the outer shell and is fitted around the second cavity. A second connection port is embedded in the inner wall of the second cavity and on the side away from the air intake grille.

[0009] Furthermore, the first sealing assembly includes a sealing frame; the top of the inner wall of the sealing frame is provided with an installation protrusion, and the inner wall of the sealing frame is slidably attached to the outer wall of the outer shell.

[0010] Furthermore, the mounting protrusion is slidably attached to the inner wall of the mounting groove, and a side sealing strip is provided at the bottom of the inner wall of the sealing frame, and the side sealing strip is slidably attached to the outer wall of the side recessed groove.

[0011] Furthermore, the second sealing assembly includes a sealing base plate; a cavity barrier block for sealing the inner wall of the second cavity is provided on one side of the top of the sealing base plate.

[0012] Furthermore, a lower sealing strip is provided on the top of the sealing base plate, and the lower sealing strip is sleeved around the cavity barrier block, and the lower sealing strip is attached to the inner wall of the lower inner groove.

[0013] The beneficial effects of this invention are:

[0014] 1. During the process of rotating the long bolt to one side, the first and second sealing components on the long bolt are brought closer to each other. During this process, the first sealing component protects the air intake grille and the connection port from dust and water, while the second sealing component protects the cavity at the bottom of the outer shell assembly from dust and water. Then, during the process of rotating the internal threaded cylinder to one side, the sealing cover protects the cavity at the top of the outer shell assembly from dust and water, and also tightens the internal threaded cylinder to the long bolt, thus achieving the purpose of dust and water protection at different positions on the top, bottom, and outer wall of the outer shell assembly.

[0015] 2. By installing the protrusion and sealing base plate and connecting them with the long bolt thread, while the long bolt is rotated to one side, the side sealing strip on the sealing frame slides and fits against the outer wall of the side inner groove. When the side sealing strip contacts the lower limit layer, it limits the downward movement of the sealing frame. At this moment, the sealing frame will be fitted around the first connection port and the air intake grille. With the double dustproof and waterproof effect of the side sealing strip and the lower limit layer, the dustproof and waterproof rating of the modular monitoring terminal shell is improved, so that the modular monitoring terminal shell is in IP66 condition.

[0016] 3. While the sealing base plate is threadedly connected to the long bolt, the long bolt is rotated to one side, extending the cavity barrier block to the inner wall of the second cavity, and the lower sealing strip to the inner wall of the lower embedded groove. This serves to provide double-layer dust and water protection for the bottom of the outer shell and the inner wall of the second cavity, thereby improving the dust and water protection level of the modular monitoring terminal shell and making the modular monitoring terminal shell meet IP66 standards.

[0026] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, 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, 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.

[0027] This invention provides a modular monitoring terminal housing structure with IP66 protection rating, including housing component 1; for example, such as... Figure 1 and Figure 2 As shown.

[0028] The outer wall of the outer casing assembly 1 is slidably connected to a first sealing assembly 2 for dust and water protection of the air intake grille and the connection port. The bottom of the outer casing assembly 1 is provided with a second sealing assembly 3 for dust and water protection of the cavity. Long bolts 4 are threadedly connected to the corners of the second sealing assembly 3 and the first sealing assembly 2. The top of the outer casing assembly 1 is provided with a sealing cover plate 5 for dust and water protection of the cavity. An internally threaded cylinder 6 is penetratingly connected to the corners of the sealing cover plate 5 and the outer casing assembly 1. A nut is provided at one end of the internally threaded cylinder 6, and the other end of the internally threaded cylinder 6 is threadedly connected to the long bolt 4.

[0029] Furthermore, the upper surface of the long bolt 4 is provided with external thread grooves in two directions, and the two external thread grooves are connected to the first sealing component 2 and the second sealing component 3.

[0030] Specifically, during the rotation of the long bolt 4 to one side, the first sealing component 2 and the second sealing component 3 on the long bolt 4 move closer to each other. During this process, the first sealing component 2 provides dust and water protection to the air intake grille and the connection port, while the second sealing component 3 provides dust and water protection to the cavity at the bottom of the outer shell assembly 1. Then, during the rotation of the internal threaded cylinder 6 to one side, the sealing cover plate 5 provides dust and water protection to the cavity at the top of the outer shell assembly 1, while also enabling the internal threaded cylinder 6 to be tightly connected to the long bolt, thus achieving the purpose of dust and water protection at different positions on the top, bottom, and outer wall of the outer shell assembly 1.

[0031] The housing assembly 1 includes a housing body 11; for example, such as Figure 3 and Figure 4 As shown.

[0032] The top of the outer casing 11 has a first cavity 12, and the top of the first cavity 12 is fitted and connected to the sealing cover plate 5. The outer wall of the outer casing 11 has mounting grooves 13 near the corners, and the inner wall of the mounting groove 13 is fixedly connected to a limit ring base 14. The bottom corner of the outer casing 11 also has a through hole 15, which communicates with the mounting groove 13. The outer wall of the outer casing 11 also has a side recessed groove 16, located at the bottom of the mounting groove 13. The top of the side recessed groove 16 is provided with an upper limit layer 17. A lower limiting layer 18 is provided at the bottom end of the side recess 16. A first connection port 19 is embedded in one side wall of the side recess 16. A second cavity 110 is provided at the bottom of the outer shell 11 on the side away from the first connection port 19. An air intake grille 111 communicating with the second cavity 110 is provided on the outer wall of the outer shell 11. A lower recess 112 is also provided at the bottom of the outer shell 11, and the lower recess 112 is fitted around the second cavity 110. A second connection port 113 is embedded in the inner wall of the second cavity 110 on the side away from the air intake grille 111.

[0033] The first sealing assembly 2 includes a sealing frame 21; for example, such as Figure 5 As shown.

[0034] The inner wall of the sealing frame 21 is provided with a mounting protrusion 22 at the top, and the inner wall of the sealing frame 21 is slidably attached to the outer wall of the outer shell 11. The mounting protrusion 22 is slidably attached to the inner wall of the mounting groove 13. The inner wall of the sealing frame 21 is also provided with a side sealing strip 23 at the bottom, and the side sealing strip 23 is slidably attached to the outer wall of the side inner groove 16.

[0035] The second sealing assembly 3 includes a sealing base plate 31; for example, such as Figure 6 As shown.

[0036] The top side of the sealing base plate 31 is provided with a cavity barrier block 32 for sealing the inner wall of the second cavity 110. The top of the sealing base plate 31 is also provided with a lower sealing strip 33, which is sleeved around the cavity barrier block 32 and is attached to the inner wall of the lower inner groove 112.

[0037] Specifically, while the mounting protrusion 22 is threadedly connected to the sealing base plate 31 and the long bolt 4, during the process of rotating the long bolt 4 to one side, the side sealing strip 23 on the sealing frame 21 is slidably attached to the outer wall of the side inner groove 16. When the side sealing strip 23 contacts the lower limit layer 18, it is used to limit the downward movement of the sealing frame 21. At this moment, the sealing frame 21 will be sleeved around the first connection port 19 and the air intake grille 111. Under the double dustproof and waterproof effect of the side sealing strip 23 and the lower limit layer 18, the dustproof and waterproof rating of the modular monitoring terminal shell is improved, so that the modular monitoring terminal shell is in an IP66 state.

[0038] While the sealing base plate 31 is threadedly connected to the long bolt 4, the long bolt 4 is rotated to one side, extending the cavity barrier block 32 to the inner wall of the second cavity 110, and the lower sealing strip 33 to the inner wall of the lower inner groove 112. This serves to provide double-layer dust and water protection for the bottom of the outer shell 11 and the inner wall of the second cavity 110, thereby improving the dust and water protection level of the modular monitoring terminal shell and ensuring that the modular monitoring terminal shell is in an IP66 state.

[0039] The working principle of the modular monitoring terminal shell structure with IP66 protection level proposed in this embodiment of the invention is as follows:

[0040] While installing the protrusion 22 and the sealing base plate 31 and the long bolt 4, the long bolt 4 is rotated to one side, and the side sealing strip 23 on the sealing frame 21 is slidably attached to the outer wall of the side inner groove 16. When the side sealing strip 23 contacts the lower limit layer 18, it is used to limit the downward movement of the sealing frame 21. At this time, the sealing frame 21 will be sleeved around the first connection port 19 and the air intake grille 111. Under the double dustproof and waterproof effect of the side sealing strip 23 and the lower limit layer 18, the dustproof and waterproof level of the modular monitoring terminal shell is improved, so that the modular monitoring terminal shell is in IP66 status.

[0041] While the sealing base plate 31 is threadedly connected to the long bolt 4, the long bolt 4 is rotated to one side, extending the cavity barrier block 32 to the inner wall of the second cavity 110, and the lower sealing strip 33 to the inner wall of the lower embedded groove 112. This serves to provide double-layer dust and water protection for the bottom of the outer shell 11 and the inner wall of the second cavity 110, thereby improving the dust and water protection level of the modular monitoring terminal shell and making the modular monitoring terminal shell meet IP66 standards.

[0042] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
