Description

Technical Field

[0001] This invention relates to the field of protective equipment technology, and in particular to a protective enclosure that can be quickly repaired. Background Technology

[0002] As a protective device for industrial production, electronic equipment operation, and precision instrument storage, the protective enclosure functions to create a relatively sealed and stable protective space for the precision components, sensitive circuits, or valuable instruments carried inside. It can reduce pollutants such as dust, water vapor, and corrosive gases in the external environment, prevent components from getting damp, short-circuited, or corroded, and also buffer the impact of external collisions and vibrations on the internal equipment, preventing deformation of precision structures or functional failure.

[0003] To facilitate the maintenance of internal equipment, some current protective enclosures employ a structure where the inner enclosure can slide relative to the protective enclosure. A self-locking device is also installed to fix the position of the inner enclosure. Specifically, common self-locking devices include snap-fit ​​types, which use the locking and unlocking of the snap-fit ​​to fix and release the inner enclosure. When maintenance of internal equipment is required, the operator first operates the self-locking device to release the inner enclosure, then pulls the inner enclosure out of the protective enclosure along the slide rail for maintenance. After maintenance is completed, the inner enclosure is pushed back into place, and the self-locking device is operated to lock the inner enclosure again.

[0004] However, if it is necessary to pause the pulling of the inner box during the maintenance process (such as adjusting tools or checking parts), it is not easy for the staff to achieve a convenient temporary stop. Instead, they need to first manually stabilize the inner box to reduce its sliding, then bend over or turn to the side to find the buckle position, and then press the buckle to make it engage with the slot. The whole process requires both hands to operate, both to fix the posture of the inner box and to align the buckle and the slot. The operation steps are cumbersome and time-consuming. Therefore, it is necessary to design a protective box that can be quickly repaired.

[0005] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Summary of the Invention

[0006] This invention provides a protective enclosure that can be quickly repaired, solving the problem that when the inner enclosure of an existing protective enclosure is pulled down during maintenance, it is not easy for staff to temporarily lock it, requiring them to manually stabilize the inner enclosure, find the buckle, and align it for locking, which is a cumbersome and time-consuming operation.

[0007] The present invention adopts the following technical solution: a protective enclosure that can be quickly repaired, comprising: A protective box, wherein two sets of slide rails are installed inside the protective box, an inner box slides inside the protective box, and a track adapted to the slide rails is installed on the inner box; The self-locking assembly is installed on the track. The self-locking assembly includes two sets of handles installed on the protective box. The handles have slidable grips. The grips are equipped with a first spring connected to the handles. The grips are equipped with a pull rod. One end of the pull rod extends into the protective box and is equipped with an adapter plate. The adapter plate is equipped with a toothed plate, and the protective box is equipped with locking plates on both sides. The locking plates are equipped with two sets of locking bars, and the locking bars have multiple sets of locking grooves. One end of the track has a rotating shaft, and the rotating shaft is equipped with a gear that can mesh with the toothed plate. One end of the rotating shaft is equipped with a locking wheel that can be adapted to the locking groove. A lubrication assembly, mounted on the protective housing, is adapted to lubricate the track and the slide.

[0008] Furthermore, the upper and lower parts of the handle are provided with sliding grooves, and the two ends of the grip are equipped with sliding balls that can slide within the sliding grooves.

[0009] Furthermore, the lubrication assembly includes guide rods installed on both sides of the protective box, guide plates slidably mounted on the guide rods, two sets of second springs installed on the upper part of the guide plates, and the second springs are sleeved on one end of the guide rods; A middle frame is installed on one side of the guide plate, and a middle plate is installed on one side of the middle frame. An arc groove is opened at the lower part of the middle plate, and multiple protrusions that are adapted to the arc groove are installed at intervals on the pull rod.

[0010] Furthermore, the second spring applies a downward elastic force to the guide plate, causing the guide plate to maintain a downward movement trend. When the guide plate is subjected to an upward force, it will compress the second spring.

[0011] Furthermore, oil reservoirs are installed on both sides of the protective box, and a central rod is installed on one side of the central frame. One end of the central rod extends into the oil reservoir and is fitted with a sealing plug. An oil passage is provided on the sealing plug, and an oil hole adapted to the oil passage is provided on the oil reservoir.

[0012] Furthermore, the upper part of the oil storage tank is connected to an oil inlet pipe, one end of which extends to the outside of the protective box and is fitted with a cap.

[0013] Furthermore, the lower part of the oil storage cylinder is connected to an oil dripping pipe, and the lubricating oil in the oil storage cylinder flows into the oil dripping pipe through the oil passage and the oil hole to form a channel.

[0014] Furthermore, the sealing plug is made of elastic rubber material, suitable for fitting inside the oil reservoir.

[0015] Furthermore, the inner diameter of the oil dripping pipe gradually decreases from one end of the oil storage cylinder to the other end, which is suitable for limiting the flow.

[0016] Furthermore, multiple sets of guide sleeves are installed on the track, and the guide sleeves are adapted to guide the pull rod.

[0017] The above-described at least one technical solution adopted in the embodiments of the present invention can achieve the following beneficial effects: By cooperating with the handle and the first spring, and combining the transmission of the lever, toothed plate, and gear, the locking wheel and locking groove can be flexibly switched. Specifically, when the staff needs to pull the inner box for maintenance, they only need to pull the handle away from the protective box. The lever will drive the adapter plate and toothed plate to move. The toothed plate will mesh with the gear and drive the shaft to rotate, causing the locking wheel to rotate out of the locking groove and unlock the inner box. If it is necessary to stop pulling the inner box during maintenance (such as adjusting tools or checking parts), the staff does not need to operate the complex structure. They only need to release the handle, and the first spring will release its elastic potential energy to push the handle back to its original position. Then, through the above transmission path, the locking wheel will rotate in the opposite direction, so that it will re-engage in the corresponding locking groove and automatically trigger the locking mechanism. The whole process does not require manual alignment of the buckle or fixation with tools, and does not require additional support brackets, simplifying the maintenance process. Furthermore, as the inner box is pulled outward, it activates the oil outlet mechanism inside the lubrication assembly, dripping a fixed amount of lubricating oil onto the slide rail. As the inner box continues to be pulled, it achieves an intermittent lubrication effect of dripping oil when pulling and stopping when pulling, thus eliminating the need for manual addition of lubricating oil. On the one hand, it replenishes lubrication to the friction parts of the slide rail, reduces resistance when the inner box is pulled, prevents scratches and wear on the slide rail due to dry friction, and extends the service life of the slide rail. On the other hand, the intermittent dripping of oil can prevent excessive waste of lubricating oil or leakage that contaminates the internal components of the equipment. At the same time, it ensures that the inner box can still maintain a smooth pulling feel after long-term use, reducing operational inconvenience caused by slide rail jamming during maintenance.

[0021] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structure, features and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0022] The technical solutions provided by the various embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0023] Reference Figure 1 , Figure 2 and Figure 5 As shown, this embodiment of the invention provides a protective enclosure that can be quickly repaired, including a protective enclosure 1. The protective enclosure 1 is used for external protection of the entire device. On both sides of the bottom of the protective enclosure 1, slide rails 11 are precisely installed by bolts. The slide rails 11 extend along the length of the protective enclosure 1, and their length is adapted to the internal space of the protective enclosure 1. The surface of the slide rails 11 has been smoothed.

[0024] Inside the protective box 1, an inner box 2 is slidably installed. The inner box 2 is mainly used to carry various precision components, sensitive circuits or valuable instruments. Its shape and size match the internal space of the protective box 1, so that the inner box 2 can be easily pulled out inside the protective box 1, which facilitates the operator to inspect and maintain the internal equipment.

[0025] On the lower part of both sides of the inner box 2, rails 21 that can be matched with slide rails 11 are firmly installed by bolts. The rails 21 and slide rails 11 cooperate with each other to form a guide rail system for sliding the inner box 2. This cooperative design makes the inner box 2 more stable during sliding, effectively reducing the occurrence of shaking or jamming, thereby better protecting the internal equipment from unnecessary damage.

[0026] See Figure 1 , Figure 4 , Figure 5 , Figure 6 and Figure 10 As shown, a self-locking component 3 is installed on the track 21. This self-locking component 3 is a structure that enables the inner box 2 to be locked and unlocked within the protective box 1. It ensures that the inner box 2 can remain stable when it does not need to slide, and prevents the inner box 2 from sliding due to accidental collisions, vibrations, or other factors, thereby causing damage to the internal equipment.

[0027] The self-locking assembly 3 includes two sets of handles 31 bolted to the lower part of one end of the inner box 2. The handles 31 are easy for the operator to grip. By operating the handles 31, the working state of the self-locking assembly 3 can be easily controlled, thereby locking and unlocking the inner box 2. Slide grooves 311 are provided on the upper and lower parts of the handles 31. A grip 312 is installed inside the handles 31. The grip 312 is the part that the operator directly operates. By pulling or releasing the grip 312, the working state of the self-locking assembly 3 can be changed. The slide grooves 311 provide a sliding track for the grip 312 and limit the sliding direction of the grip 312. At the same time, the outside of the handles 31 is covered with a rubber anti-slip sleeve (not shown in the figure). The rubber anti-slip sleeve has good anti-slip performance, which can increase the friction when the operator grips the handles 31, effectively reduce the occurrence of slippage, and make the operation more stable and reliable. Even when the hands are sweaty or oily, a good grip can be guaranteed.

[0028] At both ends of the grip 312, there are sliding balls 313 that can slide in the slide groove 311. The cooperation between the sliding balls 313 and the slide groove 311 makes the grip 312 slide more smoothly in the handle 31 and also plays a certain role in limiting the grip 312 to prevent the grip 312 from falling out of the handle 31. On one side of the grip 312, two sets of first springs 314 are fixedly installed. One end of the first spring 314 is fixedly connected to the handle 31. The first spring 314 always applies a spring force to the grip 312 towards the protective box 1, so that the grip 312 maintains the tendency to move towards the protective box 1. When the operator releases the grip 312, the grip 312 can automatically reset towards the protective box 1 under the action of the spring force of the first spring 314, thereby driving the self-locking component 3 back to the locked state. No additional reset operation is required from the operator, which improves the convenience of operation. Among them, the slider 313 is made of stainless steel. Stainless steel is wear-resistant and corrosion-resistant, which can maintain good performance during long-term sliding, extend the service life of the slider 313, reduce failures caused by wear of the slider 313, and ensure the long-term stable operation of the self-locking component 3.

[0029] A pull rod 32 is fixedly installed on the upper part of the handle 312. The pull rod 32 is used to transmit power. It can transmit the linear movement of the handle 312 to the relevant components inside the protective box 1. One end of the pull rod 32 extends into the interior of the protective box 1 and is fixedly installed with a converter plate 33. A toothed plate 331 is fixedly installed on the converter plate 33. The converter plate 33 connects the pull rod 32 and the toothed plate 331, so that the linear movement of the pull rod 32 can be smoothly converted into the movement of the toothed plate 331. At the same time, the toothed plate 331 is provided with a continuous toothed structure.

[0030] Locking plates 34 are bolted to the lower part of both sides of the protective box 1. The locking plates 34 are fixed to the protective box 1 and are one of the components in the self-locking assembly 3 that realize the locking function. Two sets of locking bars 341 are fixedly installed at the end of the locking plate 34 near the inside of the protective box 1. The locking bars 341 are set along the length of the protective box 1. Multiple locking grooves 342 are spaced apart on the locking bars 341. The shape and size of the locking grooves 342 are adapted to the subsequent locking structure. When the locking structure is engaged with the locking grooves 342, the inner box 2 can be stably locked inside the protective box 1.

[0031] At one end of the track 21, a rotating shaft 35 is rotatably connected. The rotating shaft 35 can rotate freely around its own axis. A gear 351 that meshes with the toothed plate 331 is coaxially mounted on the rotating shaft 35. At one end of the rotating shaft 35, a locking wheel 352 that matches the locking groove 342 is coaxially mounted. When the toothed plate 331 moves linearly under the drive of the pull rod 32, it will mesh with the gear 351, thereby driving the gear 351 to rotate. The rotation of the gear 351 will then be transmitted to the locking wheel 352 through the rotating shaft 35. Meanwhile, the outer periphery of the locking wheel 352 is provided with a protruding structure that matches the locking groove 342. When the locking wheel 352 rotates, these protruding structures can engage or disengage from the locking groove 342, thereby realizing the locking and unlocking operation of the inner box 2. The outer surface of the locking wheel 352 is provided with anti-slip texture. The anti-slip texture can effectively enhance the friction between the locking wheel 352 and the locking groove 342, improve the stability of self-locking, prevent the locking wheel 352 from sliding in the locking groove 342, and ensure the reliability of locking the inner box 2. Multiple guide sleeves 36 are installed on the track 21. The guide sleeves 36 play a dual role in guiding and supporting the pull rod 32, ensuring that the pull rod 32 always maintains a straight line during movement, preventing the pull rod 32 from bending or deviating, thereby improving the stability of the self-locking assembly 3. The pull rod 32 can slide smoothly along the guide sleeve 36. The inner wall of the guide sleeve 36 has also been smoothed, further reducing the frictional resistance between the pull rod 32 and the guide sleeve 36.

[0032] See Figure 4 , Figure 5 , Figure 7 , Figure 8 and Figure 9 As shown, lubrication components 4 are installed on both sides of the lower part of the protective box 1. The lubrication components 4 are used to automatically lubricate the track 21 and the slide 11, thereby reducing the friction between them, making the inner box 2 slide more smoothly, and also effectively extending the service life of the track 21 and the slide 11, reducing the overall maintenance cost of the equipment.

[0033] The lubrication assembly 4 includes two sets of guide rods 41 fixedly installed on the inner walls of both sides of the protective box 1. The guide rods 41 are set perpendicular to the bottom of the protective box 1. A guide plate 42 is slidably installed on the guide rods 41. The guide rods 41 provide vertical guidance for the sliding of the guide plate 42, ensuring that the guide plate 42 remains stable during movement and does not shift to the left or right. The guide rods 41 are all located at one end inside the protective box 1.

[0034] Two sets of second springs 43 are fixedly installed on the upper part of the guide plate 42, and the second springs 43 are sleeved on one end of the guide rod 41. The second springs 43 always apply a downward elastic force to the guide plate 42, so that the guide plate 42 maintains a downward movement tendency. When the guide plate 42 is subjected to an upward force, it will compress the second springs 43. When the upward force disappears, the elastic force of the second springs 43 will push the guide plate 42 to return to its downward position.

[0035] Meanwhile, the guide plate 42 is a moving part in the lubrication assembly 4, and its up-and-down movement controls the working state of the lubrication assembly 4. A middle frame 421 is fixedly installed on one side of the guide plate 42, and a middle plate 422 is bolted to one side of the middle frame 421. An arc groove 423 is formed in the lower part of the middle plate 422. Multiple protrusions 44, which are adapted to the arc groove 423, are fixedly installed at intervals on the pull rod 32. The shape of the arc groove 423 matches the protrusions 44 on the pull rod 32. When the pull rod... When rod 32 moves in a straight line, protrusion 44 slides in arc groove 423, thereby pushing guide plate 42 to move up and down. The protrusion 44 converts the linear motion of rod 32 into the up and down motion of guide plate 42. The outer surface of protrusion 44 is arc-shaped, which facilitates the cooperation between protrusion 44 and arc groove 423, reduces collision and wear between protrusion 44 and arc groove 423, makes the cooperation between the two smoother, extends the service life of the component, and also improves the stability of linkage operation.

[0036] Oil reservoirs 45 are fixedly installed at one end of the inner walls on both sides of the protective box 1. The oil reservoirs 45 are used to store lubricating oil and provide a continuous lubricating medium for the lubrication assembly 4. An oil inlet pipe 451 is connected to one end of the oil reservoir 45. One end of the oil inlet pipe 451 extends to the outside of the protective box 1, which makes it convenient for operators to add lubricating oil into the oil reservoir 45. A sealing head 452 is threadedly connected to one end of the oil inlet pipe 451. The sealing head 452 is used to seal the oil inlet pipe 451 to reduce dust from entering from the oil inlet pipe 451 and ensure the purity of the lubricating oil in the oil reservoir 45.

[0037] At the other end of the oil reservoir 45, there is an oil dripping pipe 453. One end of the oil dripping pipe 453 extends to the track 21. When lubricating oil flows out from the oil reservoir 45, it will drip onto the track 21 through the oil dripping pipe 453 to lubricate the track 21.

[0038] On one side of the intermediate frame 421, an intermediate rod 47 is bolted on. One end of the intermediate rod 47 extends into the oil reservoir 45 and is fixedly fitted with a sealing plug 46. The sealing plug 46 controls the outflow of lubricating oil from the oil reservoir 45. An oil passage 461 is formed on the sealing plug 46, and an oil passage hole 462 adapted to the oil passage 461 is formed on the oil reservoir 45. When the guide plate 42 moves the intermediate rod 47 up and down, the sealing plug 46 also moves accordingly, thereby aligning or offsetting the oil passage 461 and the oil passage hole 462. The sealing plug 46 is made of elastic rubber. Made of elastic rubber material, it has good sealing properties and can fit tightly against the inner wall of the oil reservoir 45, effectively preventing lubricating oil leakage. At the same time, when the oil passage 461 and the oil hole 462 are aligned, it can ensure the smooth flow of lubricating oil and ensure the lubrication effect. Meanwhile, the inner diameter of the drip tube (453) gradually decreases from one end of the oil reservoir (45) to the other end, which is suitable for limiting the flow. It plays a certain role in limiting the flow and can control the dripping speed of the lubricating oil, so that the lubricating oil drips onto the track 21 at a suitable flow rate, which not only ensures the lubrication effect but also prevents the excessive use of lubricating oil.

[0039] Specifically, when the oil passage 461 is aligned with the oil hole 462, the lubricating oil in the oil reservoir 45 can flow into the drip pipe 453 through the oil passage 461 and the oil hole 462, and then drip from the drip pipe 453 to the position of the track 21 to achieve lubrication of the track 21. When the oil passage 461 and the oil hole 462 are misaligned, the flow of lubricating oil is blocked, the lubrication operation is stopped, and the automatic control of the lubrication component 4 is realized. Oil dripping will only occur when lubrication is needed (i.e. when the inner box 2 slides), thus reducing the waste of lubricating oil.

[0040] Working principle: When the precision components, sensitive circuits or valuable instruments carried inside the protective case 1 malfunction and need to be repaired and maintained, the operator first places his hand on the rubber anti-slip sleeve on the outside of the handle 31. The increased friction from the anti-slip sleeve stabilizes the grip on the handle 31. Then, a pulling force is applied away from the protective case 1, causing the handle 312 to slide along the slide groove 311 on the upper and lower parts of the handle 31. At this time, the stainless steel ball 313 at both ends of the handle 312 slides synchronously in the slide groove 311, which reduces the frictional resistance between the handle 312 and the handle 31, and prevents the handle 312 from shifting or falling off through the limiting effect of the slide groove 311. At the same time, the two sets of first springs 314 on one side of the handle 312 are compressed, storing elastic potential energy.

[0041] As the handle 312 slides, the pull rod 32 fixed on its upper part moves linearly outward in the horizontal direction under the guidance and support of the guide sleeve 36 on the track 21. The movement of the pull rod 32 directly drives the adapter plate 33 extending into the interior of the protective box 1 to move synchronously. The toothed plate 331 fixed on the adapter plate 33 also moves horizontally accordingly. Since the toothed plate 331 meshes with the gear 351 on the rotating shaft 35 at one end of the track 21, the linear movement of the toothed plate 331 is converted into the rotational movement of the gear 351. Gear 351 drives the locking wheel 352 at one end of the rotating shaft 35 to rotate synchronously through the coaxially connected rotating shaft 35. This causes the protruding structure on the outer periphery of the locking wheel 352, which is adapted to the locking groove 342, to rotate out from the locking groove 342 of the locking bar 341 on the locking plate 34, completely releasing the locking state between the inner box 2 and the protective box 1. At this time, the operator only needs to apply a slight pushing force to smoothly pull the inner box 2 out of the protective box 1 along the sliding track 11 at the bottom of the protective box 1 and the track 21 on both sides of the inner box 2, exposing the internal equipment to be inspected.

[0042] During the linear motion of the pull rod 32, multiple arc-shaped protrusions 44 fixed at intervals on its surface will form a sliding fit with the arc groove 423 at the lower part of the intermediate plate 422 in the lubrication assembly 4. The arc-shaped surface of the protrusion 44 reduces the collision wear with the arc groove 423. As the pull rod 32 moves, the protrusions 44 push the intermediate plate 422 to move upward. The intermediate plate 422 drives the guide plate 42 to slide upward along the guide rod 41 on the inner wall of the protective box 1 through the intermediate frame 421. At this time, the second spring 43 sleeved on the guide rod 41 on the upper part of the guide plate 42 is compressed. The upward movement of the guide plate 42 is transmitted to the sealing plug 46 inside the oil reservoir 45 through the intermediate rod 47 on one side of the intermediate frame 421, so that the elastic rubber sealing plug 46 moves upward in the oil reservoir 45 until the oil passage 461 on the sealing plug 46 is completely aligned with the oil hole 462 on the side wall of the oil reservoir 45.

[0043] The lubricating oil stored in the oil reservoir 45 flows into the drip pipe 453 connected to the other end of the oil reservoir 45 through the channel formed by the oil passage 461 and the oil passage hole 462. The oil drips from the drip pipe 453 to the mating part of the track 21 and the slide 11, lubricating the contact surface between the two, further reducing the frictional resistance between the track 21 and the slide 11 during the pulling out of the inner box 2, and ensuring that the inner box 2 slides smoothly.

[0044] After the internal equipment is repaired, the operator pushes the inner box 2 along the track 21 and slide 11 to reset it inside the protective box 1. After the inner box 2 returns to its initial position, the tension on the handle 312 is released. At this time, the first spring 314 releases its stored elastic potential energy, pushing the handle 312 to reset to one side of the protective box 1. The handle 312 drives the pull rod 32, the adapter plate 33 and the toothed plate 331 to move in the opposite direction. The toothed plate 331 drives the gear 351, the rotating shaft 35 and the locking wheel 352 to reverse, so that the protruding structure of the locking wheel 352 re-engages into the locking groove 342 of the locking bar 341. The anti-slip texture on the outer surface of the locking wheel 352 enhances the friction with the locking groove 342, thus achieving stable locking of the inner box 2 inside the protective box 1.

[0045] At the same time, the second spring 43 also releases elastic potential energy, pushing the guide plate 42 to reset downward along the guide rod 41. The intermediate frame 421 drives the intermediate rod 47 and the sealing plug 46 to move downward, so that the oil passage 461 of the sealing plug 46 is misaligned with the oil passage 462 of the oil reservoir 45. The sealing plug 46 blocks the lubricating oil outflow channel through the sealing of the elastic rubber material, stops the dripping of oil, and avoids the waste of lubricating oil. Thus, the entire maintenance operation cycle is completed.
