Description

Technical Field

[0001] This utility model belongs to the field of electromagnetic valve technology, specifically relating to a protective cover for electromagnetic valves that is easy to disassemble. Background Technology

[0002] Solenoid valves are electromagnetically controlled industrial devices, fundamental components of automation used to control fluids. They are actuators, not limited to hydraulic or pneumatic systems, used in industrial control systems to adjust the direction, flow rate, speed, and other parameters of the medium. Solenoid valves can be used with different circuits to achieve the desired control, offering both precision and flexibility. A search revealed application number "CN202120243570.9" disclosing "A Protective Cover for an Easily Disassembled Solenoid Valve," which describes how, through the arrangement of a protective groove, protective plate, second adapter plate, and protective shell, during use, the operator can easily disassemble the solenoid valve... The valve is fixed in the protective groove and protective plate, and connected to the protective shell via a second adapter plate, thereby protecting the solenoid valve during operation and achieving the goal of protecting the solenoid valve and increasing its service life. Using the protective groove, protective plate, second adapter plate, and protective shell, operators can fix the solenoid valve in the protective groove and protective plate, and connect it to the protective shell via the second adapter plate, thus protecting the solenoid valve during operation and achieving the goal of protecting the solenoid valve and increasing its service life. However, the above comparison document still has the following problems in actual use:

[0003] In actual use, bolts are required for installation and disassembly, which is inefficient. Furthermore, the lack of heat dissipation and dust filtration causes dust to enter the protective cover, resulting in poor heat dissipation of the solenoid valve.

[0004] Therefore, providing a protective cover that can be quickly disassembled and installed while protecting against dust and dissipating heat is highly practical. Utility Model Content

[0005] The purpose of this invention is to provide a protective cover for a solenoid valve that is easy to disassemble, thereby solving the aforementioned technical problems.

[0006] This utility model provides a protective cover for a solenoid valve that is easy to disassemble, including a solenoid valve, a quick-release assembly, and a heat dissipation, filtration, and quick-replacement filter assembly.

[0007] The solenoid valve is covered with protective covers on both sides. Each of the two protective covers has several heat dissipation holes on one side. One of the protective covers has several sockets on one side, and the other protective cover has several plugs on one side.

[0008] The quick-release assembly includes a protective box disposed on the top of one of the protective covers. Two first hinge seats are disposed on one side of the inner wall of the protective box. A connecting rod is hinged inside each of the two first hinge seats. A locking head is disposed at one end of each of the two connecting rods. A fixing plate is disposed on the top of the other protective cover. Two insert rods are disposed on one side of the fixing plate.

[0009] The heat dissipation filtration and quick-replacement filter assembly includes connecting frames disposed on one side of two protective covers. Each connecting frame has a fixed frame at its top and bottom. A fixing bracket is interlaced within each of the two fixed frames. A filter frame is disposed between the two fixing brackets. Each connecting frame has several second hinge seats at its top and bottom. Each of the second hinge seats has a pressure rod hinged inside. A torsion spring is disposed at the connection between the second hinge seats and the pressure rod. Each pressure rod has a pressure head at its end. Two connecting rods are rotatably connected to the middle of each pressure rod. Two fans are disposed inside the connecting frame.

[0010] In one embodiment of this utility model, the driving assembly includes two fixing strips disposed at one end of the inner wall of the protective box, two limiting rods disposed between the two fixing strips, a pressing rod slidably connected to the outer wall of the two limiting rods, a spring disposed between the two pressing rods, the interior of the two springs being slidably connected to the limiting rods, and a damping rod spring disposed on one side of the middle of the two pressing rods.

[0011] In one embodiment of this utility model, a guide rod is provided on one side of each of the two pressing rods, and a third hinge seat is hinged to the end of each of the two guide rods. A sliding block is provided at one end of each of the two third hinge seats, and an auxiliary rod is slidably connected inside each of the two sliding blocks.

[0012] In one embodiment of this utility model, connecting plates are provided on both sides of the two auxiliary rods, and one end of each of the connecting plates is fixedly connected to a connecting rod.

[0013] In one embodiment of this utility model, two slots are provided on one side of the protective box, and the ends of the two insert rods are inserted into the slots. A connecting groove is provided at one end of each of the two insert rods, and the interior of each of the two connecting grooves is inserted into the slot. An auxiliary groove is provided on the other side of the protective box, and the outer walls of the two pressing rods are slidably connected to the auxiliary groove. The ends of several pressing heads are inserted through the fixing frame and connected to the fixing bracket.

[0014] In one embodiment of this utility model, both protective covers are made of polyethylene, and a controller is provided at the top corner of the other protective cover.

[0015] In one embodiment of this utility model, both the solenoid valve and the fan are electrically connected to the controller, and the controller is electrically connected to an external power supply.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1) The protective box allows users to easily align the two protective covers when installation is required. The plug is inserted into the socket and then onto the solenoid valve. While on the solenoid valve, the rod on the other protective cover is inserted into the slot within the protective box via a fixing plate. The user then squeezes the pressing rod towards the center, causing the spring and damping rod to contract and store force. This movement of the pressing rod pulls the guide rod, causing the third hinge seat to move. The third hinge seat then moves the sliding block on the auxiliary rod. The auxiliary rod and the first hinge seat work together to pull the connecting rod, moving it so that the plug enters the socket and the rod enters the slot. Once aligned, the user releases the pressing rod, causing the spring and damping rod to reset the other parts. The clip then engages the connecting groove of the rod, securing it. This allows for quick installation and removal, improving work efficiency.

[0018] 2) The built-in fan allows users to easily turn it on via the controller. The fan draws out the heat generated by the solenoid valve through the heat dissipation holes, while another fan blows in outside air to form a wind circulation. During heat dissipation, the filter on the filter frame can filter out dust, preventing dust from entering the protective cover and causing the solenoid valve to become dusty and have poor heat dissipation.

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

[0033] Example

[0034] Please see Figures 1-4 A protective cover for an easily disassembled solenoid valve includes a solenoid valve 100, a quick-release assembly 200, and a heat dissipation, filtration, and quick-replacement filter assembly 300.

[0035] Please refer to the details. Figure 1 The solenoid valve 100 is covered with protective covers 110 on both sides. Each of the two protective covers 110 has several heat dissipation holes on one side. One of the protective covers 110 has several insertion holes on one side, and the other protective cover 110 has several plugs on one side.

[0036] Please see Figures 1-3The quick-release assembly 200 includes a protective box 210 disposed on the top of one of the protective covers 110. Two first hinge seats 220 are disposed on one side of the inner wall of the protective box 210. The two first hinge seats 220 are hinged to the inside of each of the two first hinge seats 220. A locking head 240 is disposed at one end of each of the two connecting rods 230. A fixing plate 250 is disposed on the top of the other protective cover 110. Two insert rods 260 are disposed on one side of the fixing plate 250.

[0037] In one specific embodiment, the protective box 210 facilitates the user's installation of the protective cover 110. The user aligns the two protective covers 110, inserts the plug into the socket, and then places it on the solenoid valve 100. While on the solenoid valve 100, the insertion rod 260 on the other protective cover 110 is inserted into the slot within the protective box 210 via the fixing plate 250. At this point, the user squeezes the pressing rod 430 towards the center, causing the pressing rod 430 to move towards the center. This causes the spring 440 and the damping rod spring 450 to contract and store force, further pulling the guide rod 500 towards the center. Pulling the third hinge seat 600 causes the sliding block to move on the auxiliary rod 700. Then, through the cooperation of the auxiliary rod 700 and the first hinge seat 220, the connecting rod 230 is pulled, causing the connecting rod 230 to move. At this time, the plug enters the socket. When the plug rod 260 enters the slot, after alignment, the user releases the pressing rod 430, which, through the spring 440 and the damping rod spring 450, drives other parts to reset. Then, the clip head 240 is inserted into the connecting groove of the plug rod 260 to fix it, thus achieving quick installation. Disassembly is similar, thereby achieving the purpose of quick assembly and disassembly and improving work efficiency.

[0038] Please see Figures 2-4 The heat dissipation filtration and quick-replacement filter assembly 300 includes a connecting frame 310 disposed on one side of two protective covers 110. A fixing frame 320 is disposed at the top and bottom of the connecting frame 310. A fixing bracket 330 is interlaced inside each of the two fixing frames 320. A filter frame 340 is disposed between the two fixing brackets 330. Several second hinge seats 350 are disposed at the top and bottom of the connecting frame 310. A pressure rod 360 is hinged inside each of the several second hinge seats 350. A torsion spring is disposed at the connection between the several second hinge seats 350 and the pressure rod 360. A pressure head 370 is disposed at the end of each of the several pressure rods 360. Two connecting rods 380 are rotatably connected in the middle of the several pressure rods 360. Two fans 390 are disposed inside the connecting frame 310.

[0039] In one specific embodiment, the provided fan 390 allows the user to easily turn it on via a controller. The fan 390 draws out the heat generated by the solenoid valve 100 through the heat dissipation holes, while another fan blows in external air, creating a wind circulation. During heat dissipation, the filter screen on the filter frame 340 filters dust, preventing dust from entering the protective cover 110 and causing the solenoid valve 100 to become dusty and have poor heat dissipation. In use, the user can press the connecting rod 380 to lift the pressure rod 360 through the second hinge seat 350, causing the pressure head 370 to slide out from the fixing bracket 330 and the fixing frame 320, thereby releasing the restriction on the fixing bracket 330. At this time, the user can pull out the filter frame 340 and the fixing bracket 330 for cleaning, thus achieving the purpose of heat dissipation filtration and quick filter replacement.

[0040] Please see Figure 3 The drive assembly 400 includes two fixing bars 410 disposed at one end of the inner wall of the protective box 210, two limiting rods 420 disposed in the middle of the two fixing bars 410, a pressing rod 430 slidably connected to the outer wall of the two limiting rods 420, a spring 440 disposed in the middle of each of the two pressing rods 430, the interior of each of the two springs 440 being slidably connected to the limiting rods 420, and a damping rod spring 450 disposed on one side of the middle of the two pressing rods 430.

[0041] In one specific embodiment, the protective box 210 is provided to protect the internal parts during use, preventing damage to the internal parts due to bumps or knocks.

[0042] Please see Figure 3 Each of the two pressing rods 430 has a guide rod 500 on one side, and the ends of the two guide rods 500 are hinged to a third hinge seat 600. Each of the two third hinge seats 600 has a sliding block at one end, and the interior of each of the two sliding blocks is slidably connected to an auxiliary rod 700.

[0043] In one specific embodiment, the guide rod 500 is provided so that the third hinge seat 600 can be moved during use, so that the third hinge seat 600 can move on the auxiliary rod 700 through the sliding block and drive the connecting rod 230 to move.

[0044] Please see Figure 3 Both sides of the two auxiliary rods 700 are provided with connecting plates 800, and one end of each of the connecting plates 800 is fixedly connected to the connecting rod 230.

[0045] In one specific embodiment, the connecting plate 800 facilitates the support and fixation of the auxiliary rod 700 during use, making the auxiliary rod 700 more stable during use, avoiding wobbling and improving stability.

[0046] Please see Figure 3 The protective box 210 has two slots on one side, and the ends of the two insert rods 260 are inserted into the slots. One end of each insert rod 260 has a connecting groove, and the inside of each connecting groove is inserted into the clip head 240. The protective box 210 has an auxiliary groove on the other side, and the outer walls of the two pressing rods 430 are slidably connected to the auxiliary groove. The ends of several pressing heads 370 are inserted through the fixing frame 320 and connected to the fixing bracket 330.

[0047] In one specific embodiment, the provided pressure head 370 allows the user to quickly reset the pressure bar 360 via a torsion spring, thereby fixing the pressure head 370 to the fixing frame 330 and improving stability.

[0048] Please see Figure 1 Both of the protective covers 110 are made of polyethylene, and a controller is provided at the top corner of the other protective cover 110.

[0049] In one specific embodiment, the presence of polyethylene facilitates the use of the robust and durable properties of polyethylene, making the protective cover 110 more robust during use.

[0050] Please see Figure 1-4 Both the solenoid valve 100 and the fan 390 are electrically connected to the controller, which is electrically connected to an external power supply.

[0051] In one specific embodiment, the included controller facilitates power control of the electrical equipment during use, ensuring that the equipment is powered on when needed, thus avoiding situations where power cannot be supplied when required.

[0052] In use, the protective box 210 facilitates the installation of the protective cover 110. The user aligns the two protective covers 110, inserts the plug into the socket, and then places it onto the solenoid valve 100. While on the solenoid valve 100, the insertion rod 260 on the other protective cover 110 is inserted into the slot within the protective box 210 via the fixing plate 250. At this point, the user squeezes the pressing rod 430 towards the center, causing it to move closer to the center, thereby activating the spring 440 and the damping rod spring. When the 450 is compressed and stored, the pressing rod 430 moves towards the center, which in turn drives the guide rod 500 to pull the third hinge seat 600. Then, the third hinge seat 600 drives the sliding block to move on the auxiliary rod 700. Subsequently, through the cooperation of the auxiliary rod 700 and the first hinge seat 220, the connecting rod 230 is pulled, causing the connecting rod 230 to move. At this time, the plug enters the socket, and when the plug rod 260 enters the slot, after alignment, the user releases the pressing rod 430, which, through the spring 440 and the damping rod spring 450, drives the other... The parts are reset, allowing the clip 240 to engage with the connecting slot of the insert 260 for fixation, thus enabling quick installation. Disassembly follows the same principle, achieving rapid assembly and disassembly and improving work efficiency. The included fan 390 allows users to easily turn it on via the controller. The fan 390 draws out the heat generated by the solenoid valve 100 through its ventilation holes, while another fan blows in external air, creating a wind circulation. During heat dissipation, dust is filtered using the filter screen on the filter frame 340. To prevent dust from entering the protective cover 110, which could lead to excessive dust accumulation and poor heat dissipation in the solenoid valve 100, the user can press the connecting rod 380 to lift the pressure rod 360 through the second hinge seat 350, causing the pressure head 370 to slide out from the fixed bracket 330 and fixed frame 320, thereby releasing the restriction on the fixed bracket 330. At this time, the user can pull out the filter screen frame 340 and the fixed bracket 330 for cleaning, thus achieving the purpose of heat dissipation filtration and quick filter replacement.

[0053] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the 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 this utility model should be included within the protection scope of this utility model.
