Description

Technical Field

[0001] This utility model patent relates to the field of protective equipment technology, specifically to an automatic dehumidification operation box for foggy weather. Background Technology

[0002] An automatic dehumidification enclosure for foggy weather is specifically designed for high-humidity environments such as foggy weather, providing moisture protection for the equipment inside. In outdoor operations, transportation facilities, communication equipment, and other scenarios, foggy weather can cause a sharp increase in ambient humidity. Electronic components and mechanical parts inside the enclosure are susceptible to moisture corrosion, leading to malfunctions such as short circuits and rust. Therefore, a dedicated dehumidification enclosure is needed to ensure the stable operation of the equipment.

[0003] Existing dehumidification cabinets mostly employ a sealed structure combined with a dehumidification module. This seal isolates external moisture, while dehumidification elements reduce internal humidity, with the core technology aiming to minimize damage to the equipment inside. However, existing devices have significant shortcomings: firstly, the locking mechanism is laborious to operate, often using a single latch design with low opening and closing efficiency; secondly, the sealing performance is poor, and gaps easily appear after prolonged use, allowing moisture to seep in; and thirdly, the locking and dehumidification functions lack coordinated design, making them unsuitable for use in high-humidity environments.

[0004] To address the aforementioned shortcomings, the design requirements for this device are: to achieve effortless opening and closing, improve sealing reliability, and ensure efficient and stable dehumidification.

[0005] Based on the above needs, there is an urgent need to design an automatic dehumidification operation box for foggy weather, which has the technical advantages of labor-saving opening and closing, tight sealing, and stable dehumidification, and solves the pain points of existing devices in high humidity environments. Summary of the Invention

[0006] In order to solve some or all of the above-mentioned technical problems, this application provides an automatic dehumidification operation box for foggy weather, which has the technical advantages of labor-saving opening and closing, tight sealing, and stable dehumidification.

[0007] An automatic dehumidification operation box for foggy weather includes: an equipment box, a cover plate, the open edge of the equipment box being axially connected to the cover plate; a lock cylinder, the lock cylinder being mounted on the cover plate, a detection tube being provided on the inner side of the lock cylinder, a conductive liquid being placed inside the detection tube, and terminals being provided at both ends of the detection tube; a sealing ring, the sealing ring being disposed on the inner side edge of the cover plate; a dehumidifier, the dehumidifier being disposed in the equipment box, the drain pipe of the dehumidifier penetrating through the side wall of the equipment box; a lock pin, and a lock hole, the lock pin being disposed on the inner side of the cover plate, and the lock hole being disposed at the open end of the equipment box. The edge of the lock post and the lock hole are provided with multiple mutually cooperating parts; the lock post includes a rod, an electromagnet, a first spring, a slider, and an iron block. The rod is fixedly installed on the inner side of the cover plate, the electromagnet is fixedly installed in the bottom end face of the rod, the first spring is installed in the rod, and the two ends of the first spring are fixedly connected to the electromagnet and the slider. The tail end of the rod is provided with a groove, the slider slides against the groove, and the slider is constrained against the lock hole. The side of the iron block is provided with a groove rail, the groove rail is inclined, and the sliding groove in the slider slides against the groove rail.

[0008] By adopting the above technical solution, the opening and closing and locking of the enclosure are as follows: the equipment enclosure and the cover plate are connected by an edge shaft at the opening end, which can rotate around the shaft to achieve opening and closing; the lock cylinder is installed on the cover plate, and its rotation can switch the electrical connection state of the detection tube (containing conductive liquid and having terminals at both ends); the lock rod is fixed on the inside of the cover plate, and after the electromagnet in the rod is energized and de-energized, it drives the iron block to move in combination with the force of the first spring. The inclined groove rail on the side of the iron block pushes the slider along the groove at the end of the rod, so that the slider is constrained and abutted against the lock hole on the edge of the equipment enclosure, thus completing the locking or unlocking.

[0009] Optionally, when the first spring is not subjected to external force, the iron block is located at the uppermost end of the column rod, and the slider moves to the outermost side; the end of the slider facing the cover plate is inclined outward; the slot passes through the column rod, and two sliders are respectively provided on the two opposite sides of the iron block, and the two sliders slide and abut against the corresponding two slots; the rotational movement of the lock cylinder switch acts on the switching of the electrical connection and disconnection of the detection tube.

[0010] By adopting the above technical solution, the force state of the first spring is related to the initial position of the component: when the first spring is not subjected to external force, its structural characteristics of being fixedly connected to the electromagnet and the slider at both ends will drive the iron block to be stably located at the top of the column, while pushing the slider to the outermost side, providing an initial position reference for the alignment of the locking pin and the lock hole when the box is opened and closed; the slider structure is adapted to the locking operation: the end of the slider facing the cover plate is inclined outward, and during the process of the cover plate closing and the locking pin being inserted into the lock hole, the inclined surface can form a guiding fit with the edge of the lock hole, reducing the difficulty of aligning the locking pin and the lock hole;

[0011] Sliding stability of the slider is ensured: the slot penetrates the column rod, and two sliders are set on each of the two opposite sides of the iron block. The two sliders slide and abut against the corresponding slots to ensure that the sliders will not deviate or get stuck when they slide along the slots under the action of the iron block, thus maintaining a stable sliding trajectory.

[0012] Optionally, the first spring may be a plastic spring.

[0013] Optionally, a compression spring is provided between the two sliders, and the compression spring acts on the separation movement of the two sliders.

[0014] By adopting the above technical solution, based on the double slider structure of the locking column, the anti-compression spring added between the two sliders always applies a separation force to the sliders: when the locking mechanism is in the unlocked state (such as when the electromagnet is energized and the iron block moves downward), the inclined groove rail on the side of the iron block squeezes the slider, forcing the slider to overcome the elastic force of the anti-compression spring and retract towards the inside of the column, disengaging from the contact with the lock hole; when switched to the locked state (such as when the electromagnet is de-energized and the first spring resets and moves the iron block upward), the squeezing force of the inclined groove rail on the slider weakens, the anti-compression spring releases its elastic force, and pushes the two sliders to separate outward along the groove through the column, ensuring that the sliders extend stably and form a tight constraint contact with the lock hole of the equipment box.

[0015] Optionally, a plastic interlayer is provided in the equipment box and the cover plate.

[0016] In summary, compared with the prior art, this application includes at least one of the following beneficial technical effects of an automatic dehumidification operation box for foggy weather:

[0017] The adaptability and reliability of the locking mechanism are significantly improved, effectively solving the defects of existing technologies such as difficult opening and closing and easy jamming: Through the combined design of "double slider + through column groove + anti-compression spring", combined with the linkage of the inclined rail of the iron block, it not only avoids the slider from deviating to one side by means of the symmetrical separation force of the anti-compression spring, but also helps the slider to overcome the frictional resistance in high humidity environment (such as slight corrosion of parts) and retract quickly when unlocking; at the same time, the initial position setting of the first spring when it is not under external force (the iron block is at the top of the column and the slider extends to the outermost side), superimposed with the outward tilting guide structure of the slider towards the end of the cover plate, can achieve quick alignment of the locking column and the lock hole without manual adjustment. Compared with the existing single lock or locking design without auxiliary spring force, the opening and closing operation intensity is greatly reduced, and the locking process is smooth and the fit is tighter. It is suitable for the core requirements of "effort-saving + stability" of the locking mechanism in foggy and high humidity scenarios, and reduces the risk of moisture infiltration due to locking failure.

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model patent clearer, the technical solutions of the embodiments of this utility model patent will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model patent, not all of them. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model patent are within the scope of protection of this utility model patent.

[0028] Referring to the accompanying drawings, this application discloses an automatic dehumidification operation box for foggy weather.

[0029] An automatic dehumidification operation box for foggy weather includes: equipment box 1, cover plate 2, lock cylinder 3, sealing ring 6, dehumidifier 7, lock pin 8, and lock hole 9.

[0030] The edge of the opening end of the equipment box 1 is connected to the cover plate 2 by a shaft, which can rotate around the shaft to open and close.

[0031] The lock cylinder 3 is fixedly installed on the cover plate 2, and a detection tube 10 is assembled on its inner end face. The detection tube 10 is filled with conductive liquid 4, and wiring terminals 5 are set at both ends of the detection tube 10.

[0032] A sealing ring 6 is embedded in the inner edge of the cover plate 2; the dehumidifier 7 is built inside the equipment box 1, and its drain pipe extends outward through the side wall of the equipment box 1.

[0033] Multiple locking pins 8 are fixedly installed on the inner side of the cover plate 2, and multiple locking holes 9 are opened on the edge of the opening end of the equipment box 1, with the locking pins 8 and locking holes 9 being matched one by one.

[0034] In the locking pin 8, the pin rod 11 is fixed to the inner side of the cover plate 2, the inner bottom end face of the pin rod 11 is fixed with an electromagnet 12, the first spring 13 is located inside the pin rod 11, and its two ends are fixedly connected to the electromagnet 12 and the slider 14 respectively; a slot 16 is opened at the tail end of the pin rod 11, the slider 14 slides against the slot 16 and is constrained against the lock hole 9; the side of the iron block 15 is provided with an inclined groove rail 17, and the sliding groove 18 on the slider 14 slides against the inclined groove rail 17.

[0035] When opening and closing the box, simply rotate the cover plate 2 around the axis; when locking, rotate the lock cylinder 3 to switch the electrical connection state of the detection tube 10, causing the electromagnet 12 to be energized and de-energized. Combined with the extension and retraction force (elastic reset) of the first spring 13, the iron block 15 moves. The inclined groove 17 of the iron block 15 pushes the slider 14 along the groove 16 through the sliding groove 18 of the slider 14. The slider 14 extends and is constrained and abutted against the lock hole 9 to complete the locking; when unlocking, reverse the operation of the lock cylinder 3, the state of the electromagnet 12 is switched, the first spring 13 resets and causes the slider 14 to retract and disengage from the lock hole 9.

[0036] After the cover plate 2 is closed, the sealing ring 6 fills the gap between the equipment box 1 and the cover plate 2 to achieve a seal; the dehumidifier 7 works to reduce the humidity inside the box, and the condensate is discharged through the drain pipe.

[0037] The cabinet features effortless opening and closing and stable locking, a sealing ring 6 ensures basic sealing, and a dehumidifier 7 efficiently removes moisture, making it suitable for foggy and high-humidity environments. This prevents the equipment inside the cabinet from being corroded by moisture and meets core moisture protection requirements.

[0038] Example 2

[0039] Based on the structure of Embodiment 1, when the first spring 13 is not subjected to external force, the iron block 15 is stably located at the uppermost end of the column rod 11, and the slider 14 moves synchronously to the outermost side; the end of the slider 14 facing the cover plate 2 is inclined outward; the slot 16 of the column rod 11 penetrates the body of the column rod 11, and two sliders 14 are symmetrically arranged on the two opposite sides of the iron block 15, and the two sliders 14 slide against the corresponding slot 16; the rotation action of the lock cylinder 3 switch directly acts on the detection tube 10 to realize the switching of its electrical connection and disconnection.

[0040] Before opening and closing, the initial state of the first spring 13 puts the slider 14 on the outermost side, providing a reference for aligning the locking pin 8 with the lock hole 9; when the cover plate 2 is closed, the inclined end of the slider 14 engages with the edge of the lock hole 9 and is quickly inserted into the lock hole 9; the rotating lock cylinder 3 switches the electrical connection of the detection tube 10, controls the electromagnet 12 to drive the iron block 15 to move, and the double slider 14 slides stably along the through slot 16 to accurately complete locking / unlocking and avoid deviation and jamming.

[0041] It can be quickly aligned with the keyhole 9 without manual adjustment, improving opening and closing efficiency. The double slider 14 and the through slot 16 work together to make the locking action more stable, adapting to the inconvenient operation in foggy weather and further reducing the difficulty of use.

[0042] Example 3

[0043] Based on the structure of Embodiment 1, the first spring 13 in the locking column 8 is a plastic spring, that is, the two ends of the plastic spring are still fixedly connected to the electromagnet 12 and the slider 14 respectively, and are assembled inside the column rod 11.

[0044] To avoid the metal ring conducting electricity and causing interference from magnetic adsorption.

[0045] Example 4

[0046] Based on the double slider 14 structure in Embodiment 2, an anti-compression spring 19 is added between the two sliders 14. The two ends of the anti-compression spring 19 abut against the two sliders 14 respectively, and continuously apply a force in the separation direction to the two sliders 14.

[0047] When unlocking, the electromagnet 12 moves the iron block 15 downward, and the inclined groove rail 17 squeezes the slider 14. The slider 14 overcomes the elastic force of the anti-compression spring 19 and retracts inward to disengage from the lock hole 9. When locking, the electromagnet 12 is de-energized, the first spring 13 resets and moves the iron block 15 upward, the squeezing force of the groove rail 17 weakens, and the anti-compression spring 19 releases its elastic force to push the two sliders 14 outward to separate and tightly abut against the lock hole 9. The two sliders 14 slide stably along the through groove 16.

[0048] The locking mechanism fits more tightly, reducing gaps and the risk of moisture seepage; when unlocking, the auxiliary slider 14 overcomes frictional resistance and quickly resets, avoiding jamming in high humidity environments, significantly improving the reliability and smoothness of the locking mechanism.

[0049] Example 5

[0050] Based on the basic structure of Embodiment 1, a plastic interlayer is added to both the main body of the equipment box 1 and the inside of the cover plate 2. The plastic interlayer is embedded in the shell structure of the equipment box 1 and the cover plate 2.

[0051] Prevent corrosion of structural partitions.

[0052] Furthermore, when the default device (cover plate 2) is closed, the detection tube 10 is in a de-energized state; when the detection tube 10 is de-energized, the electromagnet 12 is de-energized. The electromagnet 12 is connected in sequence to the detection tube 10 and the power supply line in the equipment box 1.

[0053] To further address the issue that in extremely cold weather, the elastic deformation parameter (deformation amount) of the sealing ring 6 decreases, and a fixed sealing compression value can easily lead to insufficient sealing ring 6 protection. The elastic deformation of the first spring 13 is designed to better adapt to different temperatures and aging conditions, ensuring a safe and effective sealing deformation for the sealing ring 6.
