Description

Technical Field

[0001] This invention relates to the field of telecommunications equipment storage technology, specifically to a moisture-proof cabinet for storing telecommunications equipment and its usage method. Background Technology

[0002] As the core carrier of communication transmission and signal processing, the professionalism of the storage and preservation of telecommunications equipment directly affects its performance and lifespan. Among them, PCB boards, as the core components of telecommunications equipment, have particularly stringent requirements for the moisture-proof and storage stability of the storage environment due to the integration of a large number of precision circuits and electronic components. They have become a key focus of telecommunications equipment storage management. PCB boards must be stored in a dry and stable environment. If the humidity of the storage environment exceeds the standard, moisture will penetrate into the circuit board, causing circuit oxidation and solder joint corrosion. In severe cases, it can lead to short circuit failure of components. Therefore, moisture prevention is the core requirement for PCB board storage.

[0003] However, while existing PCB storage devices are equipped with basic moisture-proof structures, they rely on absorbent materials to adsorb moisture, making it difficult to actively expel the adsorbed moisture. This can easily lead to saturation of the absorbent materials and a significant reduction in moisture-proof efficiency. At the same time, the storage devices are not easy to transport. Some devices with casters have a small support area and insufficient stability when placed stationary, while devices without casters are difficult to move over short distances. Furthermore, PCBs are often placed directly on the placement board without a dedicated stabilizing structure, making them prone to bumps and knocks during transport and collisions, which can damage the circuit boards. Summary of the Invention

[0004] To address the problems mentioned in the background art, the present invention aims to provide a moisture-proof cabinet for storing telecommunications equipment and its usage method. This cabinet offers advantages such as flexible and stable clamping of PCB boards, convenient switching between cabinet transport and stable stationary placement, efficient adsorption of moisture inside the cabinet, regeneration of the absorbent material, long-lasting moisture protection, and convenient operation. It improves or solves, to a certain extent, the problems of existing PCB storage devices, which, although equipped with basic moisture-proof structures, rely on absorbent materials to adsorb moisture but struggle to actively expel the adsorbed moisture, easily leading to saturation of the absorbent material and significantly reducing moisture-proof efficiency. Furthermore, the storage devices suffer from poor transportability; some with wheels have a small support area and insufficient stability when stationary, while devices without wheels are difficult to move over short distances. Additionally, PCB boards are often placed directly on the storage board without a dedicated stable structure, making them prone to bumps and collisions during transport, resulting in circuit board damage.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a moisture-proof cabinet for storing telecommunications equipment and its method of use, comprising a cabinet body and a cabinet door, wherein the cabinet door is disposed on the front side of the cabinet body and is rotatably connected to the cabinet body, through slots are respectively opened at the upper and lower ends of the inner wall of the rear side of the cabinet body, a plurality of placement boards are evenly arranged inside the cabinet body, the plurality of placement boards are arranged in an up-down position, and the left and right sides are respectively fixedly connected to the inner walls of the left and right sides of the cabinet body, each placement board has three mounting slots evenly opened on its upper surface, the three mounting slots are arranged in a left-right position, and a bottom box is fixedly connected to the bottom of the cabinet body;

[0010] As a preferred embodiment of the present invention, the dehumidification assembly includes an electric heating plate and an integrated fan. The electric heating plate is disposed inside the rear end of the fixed frame and located on the rear side of the placement box, and is fixedly connected to the fixed frame. The integrated fan is fixedly connected to the rear end surface of the fixed frame.

[0011] In a preferred embodiment of the present invention, the stabilizing device includes a packaging plate, movable slots, clamping components, and a linkage component. The packaging plate is disposed at the upper end of the mounting slot and is fixedly connected to the inner wall of the mounting slot, with its upper surface flush with the upper surface of the mounting plate.

There are two clamping components, which are respectively disposed on the left and right sides of the upper end of the mounting slot. The linkage component is disposed at the lower end between the two clamping components.

[0012] In a preferred embodiment of the present invention, the clamping assembly includes a guide rod, a movable seat, a clamping plate, and a pressure rod. The two guide rods are respectively disposed on the front and rear sides inside the mounting groove, and their left and right ends are respectively fixedly connected to the inner walls of the left and right sides of the mounting groove.

Protective rubber pads are fixedly connected to the surfaces of the two clamping plates that are close to each other.

[0014] In a preferred embodiment of the present invention, the linkage assembly includes a shaft, a turntable, an arc-shaped extrusion groove, a worm gear, a worm, and a knob. The shaft is located at the center inside the mounting groove, with its upper end rotatably connected to the encapsulation plate and its lower end rotatably connected to the bottom surface inside the mounting groove. The turntable is sleeved on the surface of the shaft and fixedly connected to it. There are two arc-shaped extrusion grooves, which are respectively opened on the left and right sides of the turntable. Two pressure rods are respectively embedded in the two arc-shaped extrusion grooves and movably connected to them. The worm gear is sleeved on the lower end surface of the shaft and fixedly connected to it. The worm is located to the left of the worm gear and meshes with it. Both ends of the worm are rotatably connected to the placement plate, and its front end extends out of the placement plate. The knob is fixedly connected to the front end of the worm.

[0015] In a preferred embodiment of the present invention, the movable transfer device includes an outlet, uprights, pressure plates, a recovery spring, a gradually increasing inclined plane, casters, and an extrusion wheel assembly. There are two outlets, respectively located on the left and right sides of the bottom surface of the base box. There are four uprights, arranged in pairs, forming two groups (left and right). The four uprights are located on the front and rear sides of the two outlets, respectively. The upper and lower ends of the four uprights are fixedly connected to the upper and lower inner walls of the base box. There are two pressure plates, respectively fitted onto the upper surfaces of the left and right groups of uprights and slidably connected to them. The return spring… The number of retractable springs is four, two in a group, divided into left and right groups. The four retractable springs are respectively sleeved on the surface of the four uprights, and their upper and lower ends are respectively fixedly connected to the lower surface of the pressure plate and the bottom surface of the bottom box. The number of the gradual pressing slopes is two, and they are respectively opened on the upper side of the two pressure plates that are close to each other. The number of universal wheels is four, two in a group, divided into left and right groups, and they are respectively fixedly connected to the front and rear ends of the lower surface of the two pressure plates. The positions of the two groups of universal wheels correspond to the positions of the two outlets. The extrusion wheel assembly is located between the two pressure plates.

[0016] In a preferred embodiment of the present invention, the extrusion roller assembly includes a motor, a screw, a rotating seat, a threaded block, a pressure block, and a second progressive pressure slope. The motor is located in the center of the bottom box and is fixedly connected to the bottom surface of the bottom box. The motor has dual output ends. There are two screws, which are fixedly connected to the left and right output ends of the motor, respectively. The threads on the surfaces of the two screws have opposite directions. There are two rotating seats, which are respectively fitted onto the ends of the two screws that are far apart from each other and are rotatably connected to the screws. The lower ends of the two rotating seats are fixedly connected to the bottom surface of the bottom box. There are two threaded blocks, which are respectively fitted onto the surfaces of the two screws and are threadedly connected to the screws and slidably connected to the bottom surface of the bottom box. There are two pressure blocks, which are respectively fixedly connected to the upper ends of the two threaded blocks and slidably connected to the upper surface of the bottom box. There are two second progressive pressure slopes, which are respectively opened on the lower side of the ends of the two pressure blocks that are close to each other. The positions of the two second progressive pressure slopes correspond to and are adapted to the positions of the two first progressive pressure slopes.

[0017] In a preferred embodiment of the present invention, the first step is to place the PCB board on the upper surface of the placement plate and between the two clamping plates. Then, turn the knob, which drives the worm gear to rotate synchronously. The worm wheel meshing with the worm gear rotates accordingly and drives the shaft and turntable to rotate together. The two arc-shaped extrusion grooves on the turntable will exert an extrusion force on the pressure rods embedded in them as the turntable rotates. This pushes the two pressure rods to drive the movable seat to slide along the guide rod in a direction that brings them closer to each other. This, in turn, drives the two clamping plates to move synchronously towards each other until the protective rubber pads on the clamping plates are tightly attached to the two sides of the PCB board, thus completing the secure clamping of the PCB board. When the movable seat slides, the elastic sealing gasket in the movable groove will deform synchronously with it, ensuring the sealing effect of the mounting groove.

[0018] Step 2: Start the motor. The motor drives the screws on both sides to rotate synchronously. Since the threads on the two screws rotate in opposite directions, the two threaded blocks connected to them will slide synchronously towards each other along the bottom of the bottom box under the action of the screw rotation. As the threaded blocks move, they will also drive the upper pressure block to move together. The second gradually pressing slope on the lower side of the pressure block will press against the first gradually pressing slope on the upper side of the pressure plate. With the pressing force of the slope, the two pressure plates will slide down along the upright. At this time, the recovery spring on the surface of the upright is compressed and produces elastic deformation. As the pressure plate slides down, it will drive the universal wheel at the lower end to move down synchronously until the universal wheel passes through the outlet on the bottom of the bottom box and contacts the ground, lifting the entire cabinet of the dehumidifier and separating the bottom box from the ground. At this time, the dehumidifier can be pushed to complete the position transfer.

[0019] Step 3: After the dehumidifying cabinet is moved to the designated position, the control motor rotates in the opposite direction. The screw drives the threaded block and the pressure block to move away from each other. The squeezing force between the second and first pressure ramps disappears. The elastic restoring force of the recovery spring will push the pressure plate to slide upward along the upright, driving the caster wheel to retract upward into the bottom box. The bottom box re-contacts the ground, completing the placement and fixing of the dehumidifying cabinet and ensuring the support stability when stationary.

[0020] Step 4: During the moisture-proof process, the air entering the cabinet will have its moisture absorbed by the moisture-absorbing device placed in the dehumidification device in the groove on the back of the cabinet. When the air passes through several through holes on both sides of the placement box, the moisture contained in it will be fully absorbed by the molecular sieve moisture-absorbing particles filled inside the placement box, thereby achieving the drying treatment of the air inside the cabinet. This keeps the storage environment inside the cabinet at a low humidity level and prevents moisture from contacting the PCB board, which could cause circuit oxidation, solder joint corrosion, and other problems.

[0021] Step 5: When the molecular sieve moisture-absorbing particles reach saturation with water vapor, the dehumidification component can be activated. After the electric heating plate is powered on, it releases heat to heat and desorb the molecular sieve moisture-absorbing particles placed in the box, converting the water vapor adsorbed in the particles into water vapor. At the same time, the integrated fan starts synchronously, and the airflow generated will quickly discharge the water vapor generated by heating and desorption through the channel to the outside of the cabinet, completing the regeneration treatment of the molecular sieve moisture-absorbing particles, so that they can regain their moisture-absorbing and moisture-proof capabilities and achieve continuous operation of the moisture-proof function.

[0022] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0023] 1. This invention comprises a cabinet, cabinet door, through groove, placement plate, mounting groove, bottom box, dehumidification device, fixing frame, placement box, molecular sieve moisture-absorbing particles, through hole, dehumidification component, electric heating plate, integrated fan, stabilizing device, encapsulation plate, movable groove, clamping component, guide rod, movable seat, clamping plate, pressure rod, linkage component, shaft, turntable, arc-shaped extrusion groove, worm gear, worm, knob, movable transfer device, outlet, upright, pressure plate, recovery spring, gradual pressure slope, universal wheel, extrusion wheel assembly, motor, screw, rotating seat, threaded block, pressure block, and gradual pressure slope. Second, the combined use of elastic sealing gaskets and protective rubber gaskets improves or solves, to some extent, the problems of existing PCB storage devices, which, although equipped with basic moisture-proof structures, rely on moisture-absorbing materials to adsorb moisture but are difficult to actively expel, easily causing the moisture-absorbing materials to become saturated and significantly reducing moisture-proof efficiency. At the same time, the storage devices are not convenient to transport. Some devices with casters have a small support area and insufficient stability when placed stationary, while devices without casters are difficult to move over short distances. Moreover, PCBs are mostly placed directly on the placement board without a dedicated stable structure, making them prone to bumps and knocks during transport and collisions, causing damage to the circuit boards.

[0024] 2. This invention can efficiently adsorb moisture inside the cabinet by setting up the dehumidification device, and can also realize the regeneration and recycling of moisture-absorbing particles, which greatly improves the moisture-proof efficiency and reduces the cost of use.

[0025] 3. The present invention can flexibly clamp and fix the PCB board by setting the stabilizing device, avoiding damage from bumps during transportation, while ensuring the sealing effect of the mounting groove and helping to improve the moisture resistance inside the cabinet.

[0026] 4. By setting up this linkage component, the clamping plates can be moved synchronously in opposite directions through a simple twisting operation. The operation is convenient and the transmission stability of the clamping is high.

[0027] 5. By setting up this movable transfer device, the present invention can realize the automatic extension and retraction of the casters, taking into account both the convenience of cabinet transfer and the support stability when stationary. Attached Figure Description

[0066] Specifically, by setting up the mobile transfer device 6, the omnidirectional wheels 66 can be automatically extended and retracted, taking into account both the convenience of transferring the cabinet 1 and the support stability when it is stationary.

[0067] Furthermore, the motor 671 drives the bidirectional screw 672 to move the pressure block 675. The pressure block 675's second pressure slope 676 presses the pressure push plate 63's first pressure slope 65, pushing the pressure push plate 63 to move down and extend the universal wheel 66. The retraction spring 64 realizes the reset and retraction of the universal wheel 66.

[0068] Working principle:

[0069] During use, in the placement and positioning process, the PCB board is placed on the upper surface of the placement plate 103 and positioned between the two clamping plates 43. Then, the knob 56 is turned, which drives the worm gear 55 to rotate synchronously. The worm wheel 54 meshing with the worm gear 55 rotates accordingly and drives the shaft 51 and the turntable 52 to rotate together. The two arc-shaped extrusion grooves 53 on the turntable 52 will exert an extrusion force on the pressure rods 44 embedded in them as the turntable 52 rotates. This pushes the two pressure rods 44 to drive the moving seat 42 to slide along the guide rod 41 in a direction that is closer to each other. This, in turn, drives the two clamping plates 43 to move synchronously towards each other until the protective rubber pads 8 on the clamping plates 43 are tightly attached to the two sides of the PCB board, thus completing the clamping and stabilizing of the PCB board. When the moving seat 42 slides, the elastic sealing pad 7 in the movable groove 32 will deform synchronously with it, ensuring the sealing effect of the mounting groove 104.

[0070] During movement, the control motor 671 starts, driving the screws 672 on both sides to rotate synchronously. Because the threads on the surfaces of the two screws 672 rotate in opposite directions, the two threaded blocks 674 connected to them will slide synchronously along the bottom surface inside the base box 105 towards each other under the action of the rotation of the screws 672. As the threaded blocks 674 move, they will also drive the upper pressure block 675 to move together. The gradual pressing slope 676 on the lower side of the pressure block 675 will interact with the gradual pressing slope on the upper side of the pressure plate 63. The two pressure plates 63 are pressed together by the pressure of the inclined plane, and the two pressure plates 64 slide down along the upright 62. At this time, the recovery spring 64 on the surface of the upright 62 is compressed and produces elastic deformation. As the pressure plates 63 slide down, they will drive the universal wheels 66 at the lower end to move down synchronously until the universal wheels 66 pass through the outlet 61 on the bottom surface of the bottom box 105 and contact the ground, and lift up the entire cabinet 1 of the dehumidifying cabinet, so that the bottom box 105 is separated from the ground. At this time, the dehumidifying cabinet can be pushed to complete the position transfer.

[0071] When the dehumidifier cabinet is moved to the designated position, the control motor 671 rotates in the reverse direction, and the screw 672 drives the threaded block 674 and the pressure block 675 to move away from each other. The squeezing force between the second pressure slope 676 and the first pressure slope 65 disappears, and the elastic restoring force of the recovery spring 64 pushes the pressure plate 63 to slide upward along the upright 62, driving the caster wheel 66 to retract upward into the bottom box 105. The bottom box 105 then re-contacts the ground, completing the placement and fixing of the dehumidifier cabinet and ensuring the support stability when stationary.

[0072] During the moisture-proof process, the air entering the cabinet 1 will be absorbed by the moisture-absorbing device 2 placed in the dehumidification device 2 in the groove 102 on the back of the cabinet 1. When the air passes through several through holes 24 on both sides of the placement box 22, the moisture contained therein will be fully absorbed by the molecular sieve moisture-absorbing particles 23 filled inside the placement box 22, thereby achieving the drying treatment of the air inside the cabinet and keeping the inside of the cabinet 1 in a low-humidity storage environment, avoiding problems such as circuit oxidation and solder joint corrosion caused by moisture contacting the PCB board.

[0073] When the molecular sieve moisture-absorbing particles 23 reach saturation with adsorbed water vapor, the dehumidification component 25 can be activated. After the electric heating plate 251 is powered on, it releases heat to heat and desorb the molecular sieve moisture-absorbing particles 23 in the placement box 22, converting the water vapor adsorbed in the particles into water vapor. At the same time, the integrated fan 252 is activated, and the airflow generated will quickly discharge the water vapor generated by heating and desorption through the channel 102 to the outside of the cabinet 1, completing the regeneration process of the molecular sieve moisture-absorbing particles 23, enabling them to regain their moisture-absorbing and moisture-proof capabilities, achieving continuous operation of the moisture-proof function without the need for frequent replacement of moisture-absorbing materials, greatly improving moisture-proof efficiency and ease of use.

[0074] In summary: This is achieved by configuring the following components: cabinet 1, cabinet door 101, through groove 102, placement plate 103, mounting groove 104, bottom box 105, dehumidification device 2, fixing frame 21, placement box 22, molecular sieve moisture-absorbing particles 23, through hole 24, dehumidification assembly 25, electric heating plate 251, integrated fan 252, stabilizing device 3, sealing plate 31, movable groove 32, clamping assembly 4, guide rod 41, moving seat 42, clamping plate 43, pressure rod 44, linkage assembly 5, shaft 51, turntable 52, arc-shaped extrusion groove 53, worm gear 54, and worm 55.

It also efficiently adsorbs moisture inside the cabinet and regenerates the moisture-absorbing material, providing long-lasting moisture protection and convenient operation.

9. A moisture-proof cabinet for storing telecommunications equipment and its method of use as described in claims 1 to 8, the method of use includes the following steps: Step 1: Place the PCB board on the upper surface of the placement plate (103) and between the two clamping plates (43), then rotate the knob (56), the knob (56) drives the worm gear (55) to rotate synchronously, the worm wheel (54) meshing with the worm gear (55) rotates accordingly and drives the shaft (51) and the turntable (52) to rotate together, the two arc-shaped extrusion grooves (53) on the turntable (52) will rotate with the turntable (52) The rotation generates a squeezing force on the embedded pressure rod (44), pushing the two pressure rods (44) to drive the moving seat (42) to slide along the guide rod (41) towards each other, thereby driving the two clamping plates (43) to move towards each other synchronously until the protective rubber pad (8) on the clamping plate (43) is tightly attached to the two sides of the PCB board, thus completing the clamping and stabilizing of the PCB board. When the moving seat (42) slides, the elastic sealing pad (7) in the movable groove (32) will deform synchronously with it, ensuring the sealing effect of the mounting groove (104). Step 2: Start the motor (671). The motor (671) drives the screws (672) on both sides to rotate synchronously. Since the threads on the surfaces of the two screws (672) rotate in opposite directions, the two threaded blocks (674) connected to them will slide synchronously along the bottom of the bottom box (105) towards each other under the rotation of the screws (672). As the threaded blocks (674) move, they will drive the pressure block (675) at the top to move together. The second pressure slope (676) on the lower side of the pressure block (675) will interact with the first pressure slope on the upper side of the pressure plate (63). (65) The two pressure plates (63) are pressed together and pushed down along the upright (62) by the pressure of the inclined plane. At this time, the recovery spring (64) on the surface of the upright (62) is compressed and produces elastic deformation. While the pressure plate (63) slides down, it will drive the universal wheel (66) at the bottom to move down synchronously until the universal wheel (66) passes through the outlet (61) on the bottom surface of the bottom box (105) and contacts the ground, and lifts up the entire cabinet (1) of the dehumidifier, so that the bottom box (105) is separated from the ground. At this time, the dehumidifier can be pushed to complete the position transfer. Step 3: After the dehumidifying cabinet is moved to the designated position, the control motor (671) rotates in the opposite direction, the screw (672) drives the threaded block (674) and the pressure block (675) to move away from each other, the squeezing force of the second pressure slope (676) and the first pressure slope (65) disappears, the elastic restoring force of the recovery spring (64) will push the pressure plate (63) to slide upward along the upright (62), and drive the caster wheel (66) to retract upward into the bottom box (105), the bottom box (105) re-contacts the ground, and the placement and fixing of the dehumidifying cabinet is completed, ensuring the support stability when stationary; Step 4: During the moisture-proof process, the air entering the cabinet (1) will be adsorbed by the moisture-absorbing box (22) of the dehumidification device (2) in the back channel (102) of the cabinet (1). When the air passes through several through holes (24) on both sides of the box (22), the moisture contained therein will be fully adsorbed by the molecular sieve moisture-absorbing particles (23) filled inside the box (22), thereby achieving the drying treatment of the air inside the cabinet and keeping the cabinet (1) in a low-humidity storage environment at all times, avoiding moisture from contacting the PCB board and causing problems such as circuit oxidation and solder joint corrosion. Step 5: When the molecular sieve moisture-absorbing particles (23) reach saturation with water vapor, the dehumidification component (25) can be activated. After the electric heating plate (251) is powered on, it releases heat to heat and desorb the molecular sieve moisture-absorbing particles (23) in the placement box (22), converting the water vapor adsorbed in the particles into water vapor. At the same time, the integrated fan (252) is activated synchronously, and the generated airflow will quickly discharge the water vapor generated by the heating and desorption along the channel (102) to the outside of the cabinet (1), completing the regeneration treatment of the molecular sieve moisture-absorbing particles (23), so that they can once again have the ability to absorb moisture and prevent dampness, and realize the continuous operation of the moisture-proof function.
