DETAILED DESCRIPTION

[0020] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0021] like Figure 1-13 As shown, a signal light fault detection system for the Internet of Things includes a traffic light assembly assembled on a rod body 1, a trigger rod 8 is hingedly arranged in the rod body 1, and an electromagnet 77 fixedly installed in the rod body 1 and an iron plate 83 arranged on one side of the trigger rod 8 are magnetically matched, a torsion spring 81 arranged on the trigger rod 8 is used to store force when the electromagnet 77 magnetically attracts the iron plate 83, and a main wire 71 for supplying power to the electromagnet 77 is arranged in the rod body 1; It also includes a contact plate 74 and a main contact plate 75 and an auxiliary contact plate 76 arranged on both sides thereof. The battery pack 73 and the auxiliary contact plate 76 arranged in the rod body 1 are electrically connected. The main contact plate 75 maintains a passage with the main electric wire 71 and the traffic light group respectively when the electromagnet 77 magnetically attracts the iron plate 83. When the electromagnet 77 is powered off and stops magnetic attraction, the torsion spring 81 releases the stored force to allow the auxiliary contact plate 76 and the traffic light group to pass through.

[0022] Specifically, it also includes a transmission plate 82 fixedly mounted on the first end of the trigger rod 8 and a transposition groove 85 opened at the second end of the trigger rod 8. A main circuit board 84 is provided on one side of the second end of the trigger rod 8. The inner walls of the transposition groove 85 on opposite sides are respectively fixedly mounted with a first contact plate 86 and a second contact plate 87, and the first contact plate 86 and the second contact plate 87 are respectively electrically connected to the main circuit board 84. The top end of the electric shock plate 74 is movably arranged in the transposition groove 85. The torsion spring member 81 is sleeved on the hinge shaft of the trigger rod 8, and the two ends of the torsion spring member 81 are respectively fixedly mounted on the trigger rod 8 and the rod body 1. The electric shock plate 74 is fixedly mounted on the support frame 7. The traffic light group, the transmission plate 82, and the main circuit board 84 are respectively electrically connected.

[0023] A support frame 7 is fixedly installed in the pole body 1, and the main wire 71 and the battery pack 73 are fixedly installed on the support frame 7 respectively. A charging controller 72 which is electrically connected to the main wire 71 and the battery pack 73 respectively is fixedly installed on the support frame 7. The charging controller 72 is utilized to enable the main wire 71 to charge the battery pack 73 when powered on. The charging controller 72 plays the effect of voltage reduction and rectification. The charging controller 72 is a well-known technical means for those skilled in the art and will not be elaborated here.

[0024] Furthermore, when the main wire 71 is powered normally, the electromagnet 77 is energized to magnetically attract the iron plate 83, thereby flipping the trigger rod 8 and storing force on the torsion spring 81. At the same time, the trigger rod 8 flips to make the first contact plate 86 fit onto the main contact plate 75. At this time, the electricity of the main wire 71 acts on the main circuit board 84 along the main contact plate 75 and the first contact plate 86, and then under the action of the rectifier circuit and the control circuit provided on the main circuit board 84, the electricity and control signal on the main circuit board 84 act on the traffic light group along the transmission plate 82, thereby energizing the traffic light group and lighting it up.

[0025] Furthermore, when the main electric wire 71 is powered off due to ground construction damage or other reasons, the electromagnet 77 is powered off and stops the magnetic iron plate 83. At this time, the torsion spring 81 releases the stored force to drive the trigger rod 8 to flip and reset, and then the second contact plate 87 on the trigger rod 8 contacts the auxiliary contact plate 76 on the electric contact plate 74. At this time, the battery pack 73 supplies power, and then the electricity on the battery pack 73 acts on the main circuit board 84 along the auxiliary contact plate 76 and the second contact plate 87, and then the electricity on the main circuit board 84 and the control signal act on the traffic light group along the transmission plate 82 again, so that the traffic light group is powered on and lights up. Therefore, when the main electric wire 71 stops supplying power, the battery pack 73 continues to supply power to light up the traffic light group, thereby ensuring the normal use of the traffic light group in the short time when the main electric wire 71 is powered off, so as to maintain normal traffic order in a short time.

[0026] In order to timely detect and feedback the main line 71 fault, when the main line 71 is powered off to stop the electromagnet 77 from magnetically attracting, the torsion spring 81 releases the stored force to drive the trigger rod 8 to flip and reset, and then the second contact plate 87 on the trigger rod 8 contacts the auxiliary contact plate 76 on the electric contact plate 74, so that the battery pack 73 is powered. Therefore, a network unit electrically connected to the second contact plate 87 can be set on the main circuit board 84. When the second contact plate 87 is powered, the 3G / 4G / 5G signal in the network unit is used to feedback the circuit information, so as to timely determine the main line 71 fault. The signal light system fault monitoring and acquisition terminal currently available on the market can monitor the status of the signal light in real time. Therefore, when the terminal device detects that the signal light is powered abnormally, if the feedback signal in the network unit on the main circuit board 84 can be collected at this time, it is determined that the main line 71 is powered abnormally. If the feedback signal in the network unit on the main circuit board 84 is not collected, and the terminal device detects that the signal light is powered abnormally, it can be determined that the main circuit board 84 is faulty. Therefore, the flipping of the trigger rod 8 and the magnetic attraction between the electromagnet 77 and the iron plate 83 can realize the detection of signal light failure.

[0027] The transmission and application of 3G / 4G / 5G signals in the network unit and the traffic light system fault monitoring and collection terminal are all existing technologies and are well-known technical means to those skilled in the art, so they will not be elaborated here.

[0028] In the above technical solution, the electromagnet 77 and the magnetic iron plate 83 are utilized to enable the main wire 71 to supply power to the traffic light group normally. When the power supply of the main wire 71 is abnormal, the torsion spring 81 releases the stored force to reset the trigger rod 8, so that the battery pack 73 supplies power to the traffic light group, so that the traffic light group can operate normally in a short time, thereby ensuring the operation of traffic.

[0029] As an embodiment further provided by the present invention, the traffic light group includes three lamp assemblies, and the lamp assembly includes a substrate 5 and small lamp units 52 arranged in a circular array thereon, the small lamp units 52 include two groups of first light strips 53 and one group of second light strips 54, when the electromagnet 77 magnetically attracts the iron plate 83, the main wire 71 is electrically connected to the small lamp units 52 respectively, and when the iron plate 83 is separated from the electromagnet 77, the second light strip 54 and the battery pack 73 are connected.

[0030] Specifically, the three lamp assemblies correspond to the red light, green light and yellow light of the signal light respectively, and the two groups of first light strips 53 and the group of second light strips 54 in the lamp assembly are electrically connected to the transmission plate 82 on the trigger rod 8 respectively, and then when the main wire 71 is powered off to stop the electromagnet 77 from magnetically attracting, the torsion spring member 81 releases the stored force to drive the trigger rod 8 to flip and reset, and then the second contact plate 87 on the trigger rod 8 contacts the auxiliary contact plate 76 on the contact plate 74, so that the electricity on the battery pack 73 is transmitted to the main circuit board 84 along the auxiliary contact plate 76 and the second contact plate 87, and the corresponding control program and circuit switch set on the main circuit board 84 are utilized to control the electric energy flowing from the second contact plate 87 to the main circuit board 84 to flow to the second light strip 54 in the lamp assembly alone, so that the second light strip 54 lights up, and at this time, the illumination of the second light strip 54 is used to enable the lamp assembly to continue to illuminate and guide. Compared with two groups of first light strips 53 and one group of second light strips 54 lighting up at the same time, the battery group 73 is used to power only the second light strips 54, so that the signal light continues to operate while extending the service life of the signal light.

[0031] The main circuit board 84 is provided with corresponding control circuits, current detection and control programs, which are control technical means for those skilled in the art and will not be elaborated here.

[0032] As another embodiment provided by the present invention, it includes a first vertical plate 91 and a second vertical plate 92 fixedly installed in the rod body 1, and the top end of the trigger rod 8 is movably arranged between the first vertical plate 91 and the second vertical plate 92. A middle plate 94 electrically connected to two groups of first light strips 53 is fixedly installed on the first vertical plate 91, and a lower plate 95 electrically connected to a group of second light strips 54 is fixedly installed on the first vertical plate 91 and the second vertical plate 92 respectively. When the iron plate 83 breaks away from the electromagnet 77, the trigger rod 8 breaks away from the first vertical plate 91 and fits onto the second vertical plate 92.

[0033] Specifically, a fixed plate 9 is fixedly installed in the rod body 1, and a first vertical plate 91 and a second vertical plate 92 are respectively fixedly installed on the fixed plate 9, an upper plate 93 is also fixedly installed on the first vertical plate 91, and a central light 55 fixedly installed on the base plate 5 is electrically connected to the upper plate 93, the first light strips 53 in the three light assemblies are respectively electrically connected to the middle plate 94; the second light strips 54 in the three light assemblies are respectively electrically connected to the lower plate 95; the central lights 55 in the three light assemblies are respectively electrically connected to the upper plate 93.

[0034] When the main wire 71 is powered normally, the electromagnet 77 is energized to magnetically attract the iron plate 83, thereby flipping the trigger rod 8 and storing the torsion spring 81. At the same time, the trigger rod 8 flips to make the first contact plate 86 fit on the main contact plate 75, and the transmission plate 82 on the trigger rod 8 fits on the upper plate 93, the middle plate 94 and the lower plate 95 on the first vertical plate 91. At this time, the electricity of the main wire 71 acts on the main circuit board 84 along the main contact plate 75 and the first contact plate 86, and then under the action of the rectifier circuit and the control circuit arranged on the main circuit board 84, the main circuit The electrical and control signals on the board 84 act on the upper board 93, the middle board 94 and the lower board 95 along the transmission board 82, thereby controlling the center light 55, the first light strip 53 and the second light strip 54 to light up at the same time. In order to be able to distinguish the electrical signals emitted by the main circuit board 84, a corresponding receiving end is set on the substrate 5 serving as a circuit board to analyze and calculate the electrical signals emitted by the main circuit board 84, thereby controlling whether the lights on the substrate 5 are on. The receiving signals, signal processing and signal calculation are well-known technical means for those skilled in the art and will not be elaborated here.

[0035] When the main wire 71 is powered off to stop the magnetization of the electromagnet 77, the torsion spring 81 releases the stored force to drive the trigger rod 8 to flip and reset. At the same time, the top of the trigger rod 8 is freed from the first vertical plate 91 and attached to the second vertical plate 92. At this time, the transmission plate 82 contacts the lower plate 95 on the second vertical plate 92. Then the second contact plate 87 on the trigger rod 8 contacts the auxiliary contact plate 76 on the electric contact plate 74, so that the electricity on the battery pack 73 is transmitted to the main circuit board 84 along the auxiliary contact plate 76 and the second contact plate 87. After the data of the main circuit board 84 is processed, it is transmitted to the transmission plate 82. At this time, the electrical signal of the transmission plate 82 is transmitted to the substrate 5 of the three lamp assemblies along the lower plate 95 on the second vertical plate 92, and then the substrate 5 processes the electrical signal to control whether the second light strip 54 is lit. Therefore, after the main wire 71 is powered off, the trigger rod 8 flips and only triggers the signal to the lower plate 95, so that only the second light strip 54 is controlled to light up. Electric energy is saved by reducing the lighting of the central lamp 55 and the lamp bodies of the first lamp strip 53 .

[0036] As another embodiment provided by the present invention, the lamp assembly includes a single-opening protective cover 3 and an inner sleeve 4 inserted into the single-opening protective cover 3, and the inner wall of the inner sleeve 4 is fixedly installed with a lining plate 41 for placing the substrate 5. When the inner sleeve 4 is attached to the inner wall of the single-opening protective cover 3, the substrate 5 is attached to the lining plate 41.

[0037] Specifically, the backing plate 41 is provided with a first metal plate 56, a second metal plate 57 and a third metal plate 58. The first metal plate 56 is electrically connected with a first wire 66, the second metal plate 57 is electrically connected with a second wire 67, and the third metal plate 58 is electrically connected with a third wire 68. The first wires 66 are electrically connected to each other, the second wires 67 are electrically connected to each other, and the third wires 68 are electrically connected to each other. The first end of the third wire 68 is electrically connected to the two lower plates 95, the first end of the second wire 67 is electrically connected to the middle plate 94, and the first end of the first wire 66 is electrically connected to the upper plate 93. When the substrate 5 is placed on the backing plate 41, the wiring terminals on the substrate 5 connected to the plurality of first light strips 53 are in contact with the second metal plate 57, the wiring terminals connected to the plurality of second light strips 54 are in contact with the third metal plate 58, and the wiring terminals connected to the center light 55 are in contact with the first metal plate 56. Thus, the center light 55, the first light strip 53 and the second light strip 54 on the substrate 5 are electrically connected to the upper plate 93, the middle plate 94 and the lower plate 95 respectively under the action of the first metal plate 56, the second metal plate 57 and the third metal plate 58 and the first wire 66, the second wire 67 and the third wire 68. The single-opening shield 3 is a hard transparent plastic sleeve, and an extension rod 11 is fixedly installed on one side of the top of the rod body 1, and a mounting shell 2 is fixedly installed at the end of the extension rod 11, and a through slot 21 is opened on the mounting shell 2, and the single-opening shield 3 is fixedly installed in the through slot 21.

[0038] The substrate 5 is placed on the lining plate 41, and the wiring terminals connected to the plurality of first light strips 53 on the substrate 5 are in contact with the second metal plate 57, the wiring terminals connected to the plurality of second light strips 54 are in contact with the third metal plate 58, and the wiring terminals connected to the center light 55 are in contact with the first metal plate 56. Then the inner sleeve 4 is manually inserted into the single-opening shield 3, and the inner sleeve 4 drives the substrate 5 to move and approach the inner wall of one side of the single-opening shield 3, and then the inner wall of one side of the single-opening shield 3 and the lining plate 41 cooperate to clamp the substrate 5, so that the substrate 5 is more closely attached to the lining plate 41. When the center light 55, the first light strip 53 and the second light strip 54 on the substrate 5 light up and generate heat, the heat is transferred to the lining plate 41, and then the heat on the lining plate 41 is dissipated along the side of the lining plate 41 relative to the substrate 5. Compared with the traditional signal lamp enclosed in the shell, the substrate 5 attached to the lining plate 41 can quickly dissipate heat, thereby reducing the problem of circuit aging caused by excessive heat.

[0039] As another embodiment provided by the present invention, a sealing rubber airbag 61 is fixedly installed at one end of the inner sleeve 4 close to the inner wall of the single-opening protective cover 3. When the inner sleeve 4 is close to the inner wall of the single-opening protective cover 3, the sealing rubber airbag 61 is squeezed and deformed to cover the substrate 5.

[0040] Specifically, horizontal platforms 51 arranged in a linear array are fixedly mounted on the base plate 5 , and the first light strip 53 and the second light strip 54 are respectively fixedly mounted on the horizontal platforms 51 , and connecting rings 59 are respectively fixedly mounted on the plurality of horizontal platforms 51 .

[0041] Furthermore, by placing the substrate 5 on the lining plate 41, and then manually pushing the inner sleeve 4 to be inserted into the single-opening protective cover 3, the sealing rubber airbag 61 gradually approaches the inner wall of one side of the single-opening protective cover 3, and then the sealing rubber airbag 61 is expanded under the joint extrusion of the end of the inner sleeve 4 and the inner wall of the single-opening protective cover 3, and the expanded part of the sealing rubber airbag 61 squeezes and blocks the connecting ring 59. At this time, under the extrusion and shielding of the sealing rubber airbag 61, the substrate 5 is more closely attached to the lining plate 41, and is limited to the lining plate 41 by the sealing rubber airbag 61. Because the sealing rubber airbag 61 is attached to the single-opening protective cover 3, the sealing rubber airbag 61 is used to seal the inner sleeve 4 and the single-opening protective cover 3, so that the substrate 5 is in a sealed environment, so as to provide a good use environment for the lights and circuits on the substrate 5.

[0042] As the optimal embodiment provided by the present invention, a gripping rod 43 is fixedly installed on the inner wall of the inner sleeve 4, and a locking rod 62 that slides in the gripping rod 43 is symmetrically arranged on the outer wall of the inner sleeve 4, and the first end of the locking rod 62 is movably arranged in a slot 32 opened on the inner wall of the single-opening protective cover 3.

[0043] Specifically, the first end of the locking rod 62 is provided with a curved angle, the inner wall of the single-opening shield 3 is provided with a guide slide 31, and the card slot 32 is provided on the inner wall of the guide slide 31, the main spring 63 is fixedly installed on the locking rod 62, and the first end of the main spring 63 is fixedly installed on the inner sleeve 4.

[0044] Furthermore, by placing the base plate 5 on the lining plate 41, and then manually grasping the grasping rod 43 and pushing it to insert the inner sleeve 4 into the single-opening protective cover 3, by sliding the locking rod 62 protruding from the inner sleeve 4 along the guide slide 31, and then the curved angle on the locking rod 62 and the single-opening protective cover 3 are squeezed to compress the main spring 63 to accumulate force, as the inner sleeve 4 moves, the end of the inner sleeve 4 and the inner wall of the single-opening protective cover 3 are squeezed together to expand the sealing rubber airbag 61, at this time, the expanded part of the sealing rubber airbag 61 squeezes and blocks the connecting ring 59, because the sealing rubber airbag 61 is attached to the single-opening protective cover 3, the sealing rubber airbag 61 is used to seal the inner sleeve 4 and the single-opening protective cover 3. Then the main spring 63 releases the stored force to push the locking rod 62. At this time, the first end of the locking rod 62 is inserted into the slot 32 to lock the inner sleeve 4 on the single-opening shield 3. Therefore, the cooperation between the locking rod 62 and the main spring 63 can realize the quick installation and fixation of the inner sleeve 4 and the substrate 5 thereon.

[0045] As another embodiment provided by the present invention, a U-shaped pressure rod 65 is slidably provided on the locking rod 62, and both ends of the U-shaped pressure rod 65 slide on the inclined groove surface 64 opened on the locking rod 62 respectively to simultaneously disengage the first end of the locking rod 62 from the slot 32.

[0046] Specifically, the two ends of the U-shaped pressure rod 65 slide on the inclined groove surface 64 respectively, and then after the worker grasps and fixes the grasping rod 43, the U-shaped pressure rod 65 is pressed close to the grasping rod 43. At this time, the two ends of the U-shaped pressure rod 65 slide on the inclined groove surface 64 opened on the locking rod 62 to simultaneously disengage the first end of the locking rod 62 from the slot 32. At this time, the inner sleeve 4 and the single-opening protective cover 3 are unlocked, so that the inner sleeve 4 can be quickly taken out of the single-opening protective cover 3.

[0047] As another embodiment provided by the present invention, the outer wall of the inner sleeve 4 is fixedly mounted with an alignment airbag 6 located on one side of the sealing rubber airbag 61, and the sealing rubber airbag 61 and the curved surface portion 33 set on the inner wall of the single-opening protective cover 3 are engaged with each other to deform and squeeze the alignment airbag 6.

[0048] Specifically, the outer wall of the inner sleeve 4 is provided with a support ring 42, and the alignment airbag 6 is located between the support ring 42 and the sealing rubber airbag 61. The substrate 5 is placed on the lining plate 41, and then the inner sleeve 4 is manually pushed to be inserted into the single-opening protective cover 3. The locking rod 62 protruding from the inner sleeve 4 is slid along the guide slide 31, and then the curved angle on the locking rod 62 and the single-opening protective cover 3 are squeezed to compress the main spring 63 to accumulate force. As the inner sleeve 4 moves, the end of the inner sleeve 4 and the inner wall of the single-opening protective cover 3 are squeezed together to expand the sealing rubber airbag 61. At this time, the expanded part of the sealing rubber airbag 61 squeezes and blocks the connecting ring 59. Because the sealing rubber airbag 61 is attached to the single-opening protective cover 3, the sealing rubber airbag 61 is used to seal the inner sleeve 4 and the single-opening protective cover 3. At the same time, part of the sealing rubber airbag 61 is deformed due to the blocking of the curved surface 33 set on the inner wall of the single-opening shield 3. At this time, the deformed sealing rubber airbag 61 turns over to the alignment airbag 6, and cooperates with the limitation of the inner wall of the single-opening shield 3 to squeeze and cover the sealing rubber airbag 6, thereby further enhancing the sealing of the substrate 5 by increasing the contact surface between the sealing rubber airbag 61 and the alignment airbag 6. At the same time, the alignment airbag 6 is located on the outside of the inner sleeve 4 to reduce the radiation of the heat of the lamp body on the substrate 5 on the alignment airbag 6, thereby slowing down the aging and hardening speed of the alignment airbag 6, so as to increase the sealing time of the substrate 5. Then the main spring 63 releases the stored force to push the locking rod 62. At this time, the first end of the locking rod 62 is inserted into the card slot 32 to lock the inner sleeve 4 on the single-opening shield 3. Therefore, the inner sleeve 4 and the substrate 5 thereon are quickly installed and fixed through the cooperation of the locking rod 62 and the main spring 63.

[0049] As another embodiment further provided by the present invention, a clamping plate group arranged in a circular array is provided on the lining plate 41, and the clamping plate group includes symmetrically arranged main elastic plates 44 and a push plate 45 slidably arranged between the two main elastic plates 44, and the push plate 45 slides to push the main elastic plates 44 to deform and fit onto the side wall of the horizontal platform 51 provided on the base plate 5.

[0050] Specifically, the first end of the main elastic plate 44 is fixedly mounted on the lining plate 41. In order to further fix the substrate 5 to avoid the problem of poor contact between the substrate 5 and the lining plate 41 caused by the shaking of the rod body 1 due to natural factors, when the substrate 5 is placed on the lining plate 41, the cross table 51 is located between every two clamping plate groups, and then a plurality of push plates 45 are slid to push the two main elastic plates 44 with the push plates 45. At this time, the two main elastic plates 44 are opened and flipped over and fitted on the cross table 51 respectively. The cross table 51 is squeezed and limited by the plurality of main elastic plates 44 and the push plates 45, so that the substrate 5 is stably placed on the lining plate 41.

[0051] The way in which the multiple push plates 45 slide simultaneously may be by sliding multiple sliders on the inner sleeve 4 and respectively cooperating with the single-opening shield 3 to slide, thereby pushing the push plates 45 to slide; or by expanding the sealing rubber airbag 61 or the positioning airbag 6 to push the multiple push plates 45 to slide; or any other method known to those skilled in the art to control the simultaneous sliding of the multiple push plates 45 is possible.

[0052] As a further optimal embodiment of the present invention, it also includes extrusion blocks 46 slidably arranged in the inner sleeve 4 and corresponding to the clamping plate group respectively, and the extrusion blocks 46 are expanded and squeezed by the positioning airbags 6 to slide and push the push plates 45.

[0053] Specifically, a reset elastic plate 47 is provided on both sides of the extrusion block 46 in the inner sleeve 4, and the first end of the reset elastic plate 47 is fixedly mounted on the inner sleeve 4, and the second end of the reset elastic plate 47 pushes on the extrusion block 46 so that the extrusion block 46 fits on the alignment airbag 6. The push plate 45 is fixedly mounted on the extrusion block 46.

[0054] The substrate 5 is placed on the lining plate 41, and the wiring terminals connected to the plurality of first light strips 53 on the substrate 5 are in contact with the second metal plate 57, the wiring terminals connected to the plurality of second light strips 54 are in contact with the third metal plate 58, and the wiring terminals connected to the center light 55 are in contact with the first metal plate 56. Then the inner sleeve 4 is manually pushed and inserted into the single-opening shield 3, and the locking rod 62 protruding from the inner sleeve 4 is slid along the guide slide 31, and then the curved surface angle on the locking rod 62 and the single-opening shield 3 are squeezed to compress the main spring 63 to store force. As the inner sleeve 4 moves, the end of the inner sleeve 4 and the inner wall of the single-opening shield 3 are squeezed together to expand the sealing rubber airbag 61. At this time, the expanded part of the sealing rubber airbag 61 squeezes and blocks the connecting ring 59. Because the sealing rubber airbag 61 is attached to the single-opening shield 3, the sealing rubber airbag 61 is used to seal the inner sleeve 4 and the single-opening shield 3. At the same time, part of the sealing rubber airbag 61 is deformed due to the blocking of the curved surface portion 33 set on the inner wall of the single-opening protective cover 3. At this time, the deformed sealing rubber airbag 61 flips over to the alignment airbag 6, and cooperates with the limiting position of the inner wall of the single-opening protective cover 3 to squeeze and cover the alignment airbag 6. When the alignment airbag 6 is squeezed, the alignment airbag 6 expands, and the alignment airbag 6 located on one side of the extrusion block 46 expands to push the extrusion block 46 to slide. At the same time, the extrusion block 46 slides to push the reset elastic plate 47 to deform and accumulate force. At the same time, the extrusion block 46 drives the push plate 45 to move so that the push plate 45 pushes the two main elastic plates 44. At this time, the two main elastic plates 44 open, deform and accumulate force and flip over and fit onto the horizontal table 51 respectively. By using multiple main elastic plates 44 and push plates 45 to squeeze and limit the horizontal table 51, the substrate 5 is stably placed on the lining plate 41.

[0055] Furthermore, the sealing of the substrate 5 is further enhanced by utilizing the extrusion contact between the sealing rubber airbag 61 and the alignment airbag 6, and then the main spring 63 releases the stored force to push the locking rod 62. At this time, the first end of the locking rod 62 is inserted into the card slot 32 to lock the inner sleeve 4 on the single-opening shield 3. Therefore, the cooperation of the locking rod 62 and the main spring 63 can realize the quick installation and fixation of the inner sleeve 4 and the substrate 5 thereon.

[0056] Furthermore, when it is necessary to disassemble and repair the substrate 5, after the worker grasps and fixes the gripping rod 43, the worker presses the U-shaped pressure rod 65 to approach the gripping rod 43. At this time, the two ends of the U-shaped pressure rod 65 slide on the inclined groove surface 64 provided on the locking rod 62 to simultaneously disengage the first end of the locking rod 62 from the card slot 32. At this time, the inner sleeve 4 and the single-opening shield 3 are unlocked, so that the inner sleeve 4 can be quickly taken out of the single-opening shield 3. When the sealing rubber airbag 61 is away from the single-opening shield 3, the sealing rubber airbag 61 and the alignment airbag 6 restore their deformation, and the alignment airbag 6 releases the squeezing of the squeezing block 46. Under the elastic reset of the reset elastic plate 47 and the main elastic plate 44, the main elastic plate 44 releases the limiting fixation of the substrate 5, and the sealing rubber airbag 61 releases the shielding of the connecting ring 59, so that the substrate 5 can be quickly removed from the lining plate 41.

[0057] Therefore, by placing the substrate 5 on the lining plate 41 and pulling the inner sleeve 4 into the single-opening protective cover 3, the substrate 5 can be quickly limited and fixed, multi-layer sealed, and the inner sleeve 4 can be quickly locked on the single-opening protective cover 3, thereby facilitating the rapid disassembly and assembly of the substrate 5 for maintenance operations.

[0058] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
