Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of electromagnetic shielding, in particular to a lifting shielding door with an integrated amplitude lifting platform. BACKGROUND

[0002] In the electromagnetic compatibility test of large electronic products, the anechoic chamber as the core test site not only needs to have excellent electromagnetic shielding effectiveness and large size opening capacity of the lifting shielding door to meet the requirements of the test equipment access and the stability of the test environment, but also needs to strictly comply with the site safety escape specification, set up a convenient and reliable safety escape channel to ensure that the test personnel can quickly and safely evacuate in the event of power failure, equipment failure and other emergencies during the test to avoid safety accidents. The structure design of the lifting shielding door as the core component connecting the anechoic chamber and the outside directly affects the rationality of the safety escape channel setting and the escape efficiency, and determines the space utilization rate of the site.

[0003] However, we found in actual use that the existing lifting shielding door has a serious effective space occupation problem due to its own mechanical structure design, which not only restricts the space utilization rate of the anechoic chamber, but also greatly hinders the setting of the safety escape channel, resulting in the fact that the existing lifting shielding door cannot meet the dual requirements of space utilization and safety escape, and there are significant safety hazards and use defects. More importantly, the escape function of the existing lifting shielding door is completely dependent on its lifting action, that is, in an emergency, the entire large-size lifting shielding door needs to be completely lifted by manual or emergency driving to form an escape channel. This operation not only needs to occupy a lot of top and side space, but also the large-size door body is heavy and slow in lifting speed, and manual operation is difficult, non-professionals cannot quickly complete it, and in the event of an emergency, the door body cannot be quickly opened, which delays the escape opportunity. Therefore, we propose a lifting shielding door with an integrated amplitude lifting platform. SUMMARY

DETAILED DESCRIPTION

[0036] With reference to the drawings of the embodiments of the present application, the technical solutions in the embodiments of the present application will be described clearly and completely. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of the present application.

[0037] Embodiment 1: Please refer to Figures 1-12 The present application provides a technical solution: a lifting shielding door with an integrated width-variable lifting platform, comprising a lifting system 1, a support frame 2, and a lifting shielding door body 3, further comprising:

[0038] An emergency slot 4 is provided in the lifting shielding door body 3, and an emergency door 5 is rotatably provided on one side of the lifting shielding door body 3 through a rotating shaft and cooperates with the emergency slot 4;

[0039] A plurality of lock plates 6 are provided and are slidingly arranged in the support frame 2, and the top of each of the plurality of lock plates 6 and the end close to the emergency door 5 are beveled. When the emergency slot 4 is in an open state by using the plurality of lock plates 6, the lifting shielding door body 3 cannot rise along the support frame 2 under the power of the lifting system 1;

[0040] A passing assembly 7 is arranged on the lifting shielding door body 3 and the emergency door 5, and the passing assembly 7 is used to drive the emergency door 5 to rotate on the lifting shielding door body 3 and to drive the emergency door 5 to block or open the emergency slot 4;

[0041] A triggering assembly 8 is arranged in the lifting shielding door body 3 and the support frame 2, and the triggering assembly 8 is used to drive the emergency door 5 to block the emergency slot 4, so that the plurality of lock plates 6 retract and disengage from the restriction of the lifting shielding door body 3, and then the lifting shielding door body 3 can be lifted along the support frame 2 under the action of the lifting system 1.

[0042] The emergency door 5 is hollow, and a conductive elastic sealing strip 9 is arranged on the outer side of the emergency door 5. The conductive elastic sealing strip 9 is continuously arranged along the outer peripheral contour of the emergency door 5, and the conductive elastic sealing strip 9 on the outer side of the emergency door 5 forms a surface contact with a metal frame on the outer side of the lifting shielding door body 3. The function is that when the emergency door 5 is in a blocking state, the elastic compression deformation fills the assembly gap between the two, thereby forming a continuous conductive path, ensuring that the electromagnetic shielding integrity of the whole lifting shielding door body 3 is not affected by the emergency door 5, so that when the emergency door 5 and the emergency slot 4 are in a blocking state, the lifting shielding door body 3 can maintain complete electromagnetic shielding effectiveness. The hollow design of the emergency door 5 can significantly reduce the self-weight of the whole emergency door 5, reduce the required driving torque in the rotating process, and further reduce the force intensity required by the operator to open the emergency door 5.

[0043] The passage component 7 includes a guide 10 installed on the emergency door 5 to guide staff to observe the location of the emergency door 5. The emergency door 5 and the lifting shielding door body 3 are equipped with positioning components 11 to fix the position of the emergency door 5 after it blocks the emergency slot 4. The emergency door 5 is equipped with a handle 12 to drive the emergency door 5 out of the blocking state of the emergency slot 4.

[0044] The guide component 10 includes an exit sign 101 installed on the emergency door 5. The emergency door 5 is equipped with two emergency lights 102, and both the exit sign 101 and the two emergency lights 102 are located on the inward side of the lifting platform door body 3. If the staff is inside and needs to exit from the room, the exit sign 101 and the emergency lights 102 on the emergency door 5 can clearly indicate the direction of the emergency door 5. It should be noted that the exit sign 101 and the emergency lights 102 are both powered by independent power supply modules. Their power lines do not pass through the main control system and the driving circuit of the lifting platform door body 3, ensuring that they can continue to illuminate and indicate in the event of power failure, communication interruption or complete failure of the control system. This is existing technology and will not be described in detail here.

[0045] The positioning component 11 includes a positioning groove 111 formed on the lifting platform screen door body 3. A positioning plate 112, which works in conjunction with the positioning groove 111, is slidably disposed inside the emergency door 5. The end of the positioning plate 112 away from the emergency door 5 is inclined. A sliding groove 113 is formed on the emergency door 5, and the positioning plate 112 is slidably disposed within the sliding groove 113. A fixing plate 114 is provided inside the emergency door 5. A connecting plate 115 is provided at the end of the positioning plate 112 near the fixing plate 114, and the connecting plate 115 is slidably disposed inside the emergency door 5. A positioning spring 116 is provided between the connecting plate 115 and the fixing plate 114, with both ends of the positioning spring 116 respectively located on opposite sides of the connecting plate 115 and the fixing plate 114. The push-pull handle 122 drives the push-pull plate 121 to slide along the guide groove 124, thereby driving the connecting plate 115 to slide the positioning plate 112 within the sliding groove 113, and further driving the positioning plate 112 to disengage from the positioning groove formed inside the lifting platform screen door body 3. When the positioning plate 112 is completely disengaged from the positioning groove 111, the positioning spring 116 on one side of the positioning plate 112 begins to compress and store force. After the positioning plate 112 is completely disengaged from the positioning groove 111, the emergency door 5 can be pulled, causing the emergency door 5 to rotate on one side of the lifting shielding door body 3 via the pivot, thereby fully opening the emergency slot 4. At this time, the staff can enter the shielded area through the emergency slot 4 to carry out maintenance or emergency response operations. The positioning spring 116 set between the fixed plate 114 and the positioning plate 112 will provide elastic restoring force during the process of the staff resetting the emergency door 5, ensuring that the positioning plate 112 is re-embedded in the positioning groove 111 under the rebound action of the positioning spring 116, realizing reliable locking between the emergency door 5 and the lifting shielding door body 3. Its function is to ensure that the emergency door 5 can still be unlocked and opened by a purely mechanical means when the power is cut off or the control system fails, thereby ensuring the safety of personnel passage and the redundancy and reliability of the overall function of the lifting shielding door body 3.

[0046] The handle 12 includes push-pull plates 121 on both sides of the connecting plate 115. Each of the two push-pull plates 121 has a push-pull handle 122 on its opposite side. Each side of the emergency door 5 has a push-pull groove 123, and the two push-pull handles 122 are slidably disposed in the corresponding push-pull grooves 123. Each of the two push-pull plates 121 has a guide groove 124 on its opposite side. In case of emergency such as power failure, when personnel need to enter or exit, the operator can manually pull the push-pull handle 122 to drive it to slide in the corresponding push-pull groove 123 and pull it along the direction of the guide groove 124 on the push-pull plate 121. This allows the push-pull handle 122 to drive the connecting plate 115 to slide along the guide groove 124 through the push-pull plate 121. Its function is to ensure that in abnormal working conditions such as power failure, the operator can quickly unlock and release the emergency door 5 by manually applying linear pulling force, thereby avoiding the risk of loss of opening and closing function due to failure of the electronic control system.

[0047] The triggering component 8 includes a locking member 13 disposed on the support frame 2 and the lifting platform screen door body 3. The locking member 13 is used in conjunction with multiple locking plates 6. Each of the multiple locking plates 6 is provided with a limiting member 14 on the side away from the lifting platform screen door body 3. The multiple limiting members 14 are used to restrict the movement trajectory of the multiple locking plates 6. The lifting platform screen door body 3 is provided with a pressing member 15. The pressing member 15 is used to press the multiple locking plates 6, causing the multiple locking plates 6 to simultaneously disengage from the lifting platform screen door body 3.

[0048] The locking element 13 includes multiple rear grooves 131 formed within the support frame 2, each rear groove 131 engaging with an adjacent locking plate 6. A front groove 132 is formed within the lifting platform screen door body 3 to engage with the multiple locking plates 6. Each locking plate 6 has a locking spring 133 at its end furthest from the emergency door 5, and the other end of each locking spring 133 is located within a corresponding rear groove 131. When the multiple locking plates 6 are pressed by the protrusion 153, each locking plate 6 slides from the front groove 132 within the lifting platform screen door body 3 to the rear groove 131 within the support frame 2 under the lateral thrust of the protrusion 153, thereby releasing the mechanical interference of the locking plates 6 on the lifting and lowering movement of the lifting platform screen door body 3. During this process, the locking spring 133 at the other end of the locking plate 6 is compressed and stores energy, providing a reverse driving force for the locking plate 6 to return to its original position. At this time, the locking plate 6 is fully engaged before the lifting and lowering action begins. The locking plate 6 detaches from the front slot 132 and remains stably in the rear slot 131. The top of the locking plate 6 is sloped to facilitate the lowering of the lifting screen door body 3. During this process, the locking plate 6 is squeezed back into the rear slot 131 by the bottom of the lifting screen door body 3 until the lifting screen door body 3 is completely lowered. Then, the locking plate 6 will be locked into the front slot 132 opened in the lifting screen door body 3 under the action of the locking spring 133. The purpose is to ensure that the normal lowering function of the lifting screen door body 3 is not affected, while ensuring that the lifting action can only be performed when the emergency door 5 is closed. The purpose is to ensure the mechanical constraint of the lifting action by the closed state of the emergency door 5, so as to prevent the lifting screen door body 3 from forcibly performing the lifting action when the emergency slot 4 is not fully closed due to misoperation or abnormal control system, thereby posing a substantial threat to the safety of personnel and equipment.

[0049] The limiting member 14 includes first limiting plates 141 respectively disposed at the ends of multiple locking plates 6 away from the emergency door 5. Second limiting plates 142 are slidably disposed within each of the first limiting plates 141. Limiting grooves 143 are formed on both sides of each of the first limiting plates 141. Limiting blocks 144 are provided on both sides of each of the second limiting plates 142, and the limiting blocks 144 are slidably disposed within corresponding limiting grooves 143. The ends of the second limiting plates 142 away from the first limiting plates 141 are respectively disposed within corresponding rear grooves 131. When the locking plate 6 slides from the front groove 132 to the rear groove 131 under the pressure of the protrusion 153, the first limiting plate 141 at one end of the locking plate 6 will slide outside the second limiting plate 142, so that the first limiting plate 141 cooperates with the second limiting plate 142 to slide the locking plate 6. The movement path is restricted to prevent the locking plate 6 from deflecting or tilting during sliding, ensuring its precise displacement along the straight guide path formed by the front groove 132 and the rear groove 131. The limiting grooves 143 on both sides of the first limiting plate 141 will limit the lateral displacement distance of the first limiting plate 141 through the limiting blocks 144 on both sides of the second limiting plate 142 during the rebound of the locking spring 133. This prevents the locking plate 6 from laterally shifting or falling off the guide track due to excessive spring force of the locking spring 133. Its function is to ensure that the locking plate 6 maintains stable sliding along the preset straight guide path during the sliding process from the front groove 132 to the rear groove 131 and from the rear groove 131 to the front groove 132, and to avoid the locking plate 6 getting stuck, jumping out of the groove, or failing to guide due to assembly tolerance, spring overload, or external force disturbance.

[0050] The extrusion component 15 includes an extrusion groove 151 formed within the lifting platform screen door body 3. The extrusion groove 151 communicates with multiple front grooves 132. An extrusion plate 152 is slidably disposed within the extrusion groove 151. The side of the extrusion plate 152 closest to the emergency door 5 is inclined, and the inclined surface of the extrusion plate 152 faces the closing direction of the emergency door 5. Multiple protrusions 153 are provided at the end of the extrusion plate 152 away from the emergency door 5, and the multiple protrusions 153 are slidably disposed within the corresponding front grooves 132 and the extrusion groove 151, and cooperate with the adjacent locking plate 6. Multiple extrusion rods 154 are provided at the end of the extrusion plate 152 away from the emergency door 5. An auxiliary groove 155 is provided to cooperate with multiple compression rods 154. Each compression rod 154 has a compression spring 156 at its end away from the compression plate 152. The other ends of the compression springs 156 are respectively located in the corresponding auxiliary groove 155. When the operator needs to raise the lifting shielding door body 3, the emergency door 5 is in the open state. Multiple locking plates 6 are located between the support frame 2 and the lifting shielding door body 3. Therefore, the emergency door 5 must first be reset to completely close the emergency slot 4. When the emergency door 5 is about to be inserted into the emergency slot 4, the edge of the emergency door 5 will first contact the inclined surface of the compression plate 152. 2. The pressure plate 152 slides along the compression groove 151 under the oblique pushing force applied by the edge of the emergency door 5, forcing the compression plate 152 to overcome the elastic force of the compression spring 156 and push the multiple protrusions 153 on its other side to slide in the front groove 132 until the multiple protrusions 153 push the corresponding locking plate 6. When the compression plate 152 is compressed and pushes the protrusions 153, the compression rod 154 set on one side of the compression plate 152 will slide in the corresponding auxiliary groove 155 under the action of the compression plate 152, thereby compressing and storing energy for the compression spring 156, providing elastic reset power for the subsequent reset of the compression plate 152, ensuring that the compression plate 152 will be reset after the emergency door 5 is reopened. 152 is reset under the action of the spring 156, and each protrusion 153 is released from the pressure on the locking plate 6. The pressing rod 154 can also limit the movement trajectory of the pressing plate 152 while the pressing plate 152 is moving, thereby ensuring that the pressing plate 152 slides stably along the predetermined straight path and avoids jamming or wear due to uneven load or lateral force. Its function is to ensure that during the closing and resetting process of the emergency door 5, the continuous contact between the inclined surface of the pressing plate 152 and the edge of the emergency door 5 drives the protrusion 153 to accurately push the locking plate 6 away from the front groove 132 opened on the lifting shield door body 3, so that the lifting shield door body 3 can be raised smoothly.

[0051] In use, during emergencies such as power outages, when personnel need to enter or exit, the operator can manually pull the push-pull handle 122, causing it to slide into the corresponding push-pull groove 123. The operator then pulls the handle 122 along the guide groove 124 on the push-pull plate 121, causing the connecting plate 115 to slide along the guide groove 124 via the push-pull plate 121. This drives the connecting plate 115 to slide the positioning plate 112 into the sliding groove 113, thereby disengaging the positioning plate 112 from the positioning groove 111 within the lifting shielding door body 3. At this time, the positioning spring 116 on one side of the positioning plate 112... The compression and storage process begins. Once the positioning plate 112 is completely disengaged from the positioning groove 111, the emergency door 5 can be pulled, causing it to rotate on one side of the lifting shielding door body 3 via the pivot. This fully opens the emergency slot 4, allowing personnel to enter the shielded area through the emergency slot 4 to carry out maintenance or emergency response operations. The positioning spring 116, located between the fixed plate 114 and the positioning plate 112, provides elastic restoring force during the process of personnel resetting the emergency door 5, ensuring that the positioning plate 112 is re-embedded in the positioning groove 111 under the rebound action of the positioning spring 116, thus achieving reliable locking between the emergency door 5 and the lifting shielding door body 3.

[0052] If staff are indoors and need to exit from indoors, the exit sign 101 and emergency light 102 on emergency door 5 can clearly indicate the direction of emergency door 5. It should be noted that the exit sign 101 and emergency light 102 both use independent power supply modules, and their power lines do not pass through the main control system and the drive circuit of lifting shield door body 3, ensuring that they can continue to illuminate and indicate in the event of power failure, communication interruption or complete failure of control system. This is existing technology and will not be elaborated on here.

[0053] When power is restored and the staff needs to raise the lifting shielding door body 3, the emergency door 5 is in the open position. Multiple locking plates 6 are located between the support frame 2 and the lifting shielding door body 3. Therefore, the emergency door 5 must first be reset to completely seal the emergency slot 4. Just as the emergency door 5 is about to be inserted into the emergency slot 4, the edge of the emergency door 5 will first contact the inclined surface of the pressing plate 152. The pressing plate 152, subjected to the oblique thrust applied by the edge of the emergency door 5, slides along the pressing groove 151, forcing the pressing plate 152 to overcome the elastic force of the pressing spring 156 and push the multiple protrusions 153 on its other side to slide in the front groove 1. Within 32, until multiple protrusions 153 push the corresponding locking plates 6 respectively, when the pressing plate 152 is pressed and pushes the protrusions 153, the pressing rod 154 set on one side of the pressing plate 152 will slide in the corresponding auxiliary groove 155 under the action of the pressing plate 152, thereby compressing the pressing spring 156 to store energy, providing elastic reset power for the subsequent reset of the pressing plate 152, ensuring that after the emergency door 5 is opened again, the pressing plate 152 resets under the action of the rebound force of the pressing spring 156, and the protrusions 153 are released from pressing the locking plates 6. The pressing rod 154 can also move within the pressing plate 152. While moving, the movement trajectory of the pressing plate 152 is restricted to ensure that the pressing plate 152 slides stably along a predetermined straight path, avoiding jamming or wear due to off-center load or lateral force. When multiple locking plates 6 are pressed by the protrusion 153, each locking plate 6 slides from the front groove 132 opened in the lifting screen door body 3 to the rear groove 131 opened in the support frame 2 under the lateral thrust of the protrusion 153, thereby releasing the mechanical interference of the locking plates 6 on the lifting screen door body 3. During this process, the locking spring 133 set at the other end of the locking plate 6 will be compressed and stored to reset the locking plate 6. Provides reverse driving force. At this time, the locking plate 6 completely disengages from the front groove 132 and remains stably in the rear groove 131 before the lifting action is started. The top of the locking plate 6 is inclined so that during the process of lifting the shielding door body 3, the locking plate 6 is squeezed back into the rear groove 131 by the bottom of the lifting shielding door body 3. Until the lifting shielding door body 3 is completely lowered, the locking plate 6 will be locked into the front groove 132 opened in the lifting shielding door body 3 under the action of the locking spring 133. The purpose is to ensure that the normal lowering function of the lifting shielding door body 3 is not affected, while ensuring that the lifting action can only be performed when the emergency door 5 is closed.

[0054] As the locking plate 6 slides from the front groove 132 to the rear groove 131 under the pressure of the protrusion 153, the first limiting plate 141 set at one end of the locking plate 6 will slide outside the second limiting plate 142, so that the first limiting plate 141 and the second limiting plate 142 restrict the sliding path of the locking plate 6, thereby preventing the locking plate 6 from deflecting or tilting during the sliding process, and ensuring that it is accurately displaced along the straight guide path formed by the front groove 132 and the rear groove 131. The limiting grooves 143 on both sides of the first limiting plate 141 will limit the lateral displacement distance of the first limiting plate 141 through the limiting blocks 144 on both sides of the second limiting plate 142 during the rebound of the locking spring 133, so as to prevent the locking plate 6 from moving laterally or leaving the guide track due to the excessive elastic force of the locking spring 133.

[0055] Once the emergency door 5 has completely blocked the emergency slot 4, the lifting system 1 can be started. The lifting system 1 will then drive the lifting shielding door body 3 to rise vertically along the guide rail in the support frame 2, thereby ensuring the safety of the lifting shielding door body 3 and the emergency door 5.
