Description

Technical Field

[0001] The present invention relates to the technical field of personnel security inspection equipment, and in particular to a personnel security inspection device based on power grid on-site management. Background Art

[0002] During the construction of the power grid, in order to ensure the safety of the construction process, construction workers are prohibited from bringing metal objects such as keys, mobile phones, watches, necklaces, earrings, etc. into the construction site, as these metal objects may pose a threat to the safety of the construction site. At the same time, security equipment can prevent people from bringing illegal and prohibited items into the construction site. For example, security gates can detect some illegal items, such as drugs, guns, ammunition, etc., to ensure the safety of the construction process.

[0003] Existing personnel security inspection devices mainly use security gates. After construction workers pass through the security gate, if they carry metal objects or dangerous prohibited items, the security gate will sound an alarm. At this time, the security personnel at the security gate will manually search for the construction workers who triggered the security gate alarm to promptly discover and confiscate the metal objects or dangerous prohibited items.

[0004] In the existing technology, since a large number of construction workers often participate in the construction process of the power grid, a large number of people need to pass through the security inspection equipment. As a result, when the security personnel supervise the construction workers passing through the security inspection equipment, it is inevitable that they will not be able to timely detect the alarm issued by the security inspection equipment when some individuals carry potentially prohibited items on their bodies. This leads to loopholes in the personnel security inspection work and makes it impossible to detect dangerous factors in a timely and reliable manner. Summary of the Invention

[0005] The purpose of the present invention is to provide a personnel security inspection device based on power grid on-site management to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned objectives, the present invention provides the following technical solution: a personnel security inspection device based on power grid on-site management, comprising: a security inspection door and two base plates; the left sides of the two base plates are connected to the security inspection door via a connecting assembly; the tops of the two base plates are symmetrically fixedly connected to two first vertical plates; two through cavities are symmetrically defined on the side faces of the two first vertical plates that are separated from each other; the two base plates are connected to a first passage assembly for allowing personnel carrying dangerous goods to pass through, and a second passage assembly for allowing personnel not carrying dangerous goods to pass through; The first passage assembly includes two pairs of second vertical plates symmetrically connected to the tops of the two bottom plates. The tops of the first passage assembly are symmetrically connected to two hollow tubes, the two hollow tubes are located between the adjacent side surfaces of the two pairs of bottom plates, and two first baffles are symmetrically fixedly sleeved on the outer circumferences of the two hollow tubes. The two through cavities are respectively aligned with the two first baffles. The second passage assembly includes two connecting plates symmetrically connected to the two bottom plates, and the tops of the two connecting plates are symmetrically connected to two second baffles via two rotating mechanisms.

[0007] Preferably, the first passage assembly also includes a locking mechanism symmetrically connected to the two base plates, and the locking mechanism is used to connect and lock the first baffle to the second vertical plate. The advantage of this arrangement is that the first baffle can be locked and connected to the second vertical plate through the locking mechanism, thereby ensuring that the first baffle can block the passage between the two pairs of second vertical plates when needed, so that people can only leave through the passage between the two pairs of second vertical plates with the consent of the staff.

[0008] Preferably, the locking mechanism includes a straight rod movably inserted in the top end of the hollow tube, the top end of the hollow tube is provided with a plurality of limiting grooves in an annular shape with equal angles, the outer circumferential surface of the straight rod is fixedly connected with a plurality of limiting strips in an annular shape with equal angles, and the plurality of limiting strips are respectively slidably connected in the plurality of limiting grooves, and the top end of the straight rod is fixedly connected to the grip rod, and the locking mechanism also includes a first transverse groove provided on the left side of the first baffle, the left end of the first transverse groove is connected to the inner hole of the hollow tube, a fixing plate is slidably connected in the first transverse groove, and a pull rope is fixedly connected to the left side of the fixing plate, and the end of the pull rope away from the fixing plate passes through the first transverse groove and the inner hole of the hollow tube and is fixedly connected to the bottom end of the straight rod. The right side of the fixed plate is fixedly connected with an insertion rod, and two slots are symmetrically provided on the left side of the second vertical plate on the right side. The right end of the insertion rod passes through the right side wall of the first baffle and is movably inserted into the slot. A first elastic member is fixedly connected between the right side of the fixed plate and the right inner wall of the first transverse groove. The advantage of this arrangement is that the staff only needs to hold the grip and pull the straight rod upward. The straight rod overcomes the elastic force of the first elastic member through the pull rope and pulls the fixed plate to the left. Then the fixed plate pulls the insertion rod out of the slot. Then the staff rotates the grip to drive the first baffle to rotate until the passage between the two pairs of second vertical plates is opened to allow people who may be carrying prohibited items to come out.

[0009] The lockhole that is formed on the two sides of the two support brackets is formed on the support bracket of the second rim, and the lockhole that is formed on the two sides of the two support brackets is formed on the support bracket of the second rim. When the two locking plates are fully engaged on the left and right side walls of the security door, the two limiting plates will rotate into the installation grooves. When the locking plates are fully engaged on the left and right side walls of the security door, the two limiting plates will rotate out of the installation grooves under the elastic force of the first torsion spring and be located on the left side of the security door. In this way, the cross plate and the security door can be firmly connected together, and when the security door and the cross plate need to be disassembled and separated, it is only necessary to rotate the screw to the left until the right end of the screw is pulled out of the receiving groove, and then pull the bottom plate to the right. At this time, the limiting plate will rotate to the left into the receiving groove, thereby ensuring that the cross plate can be smoothly separated from the security door.

[0010] Preferably, the connecting assembly also includes a second elastic member fixedly connected between the left side of the movable block and the left inner wall of the mounting groove. The advantage of this arrangement is that under the elastic force of the second elastic member, the right side of the limiting plate can be tightly pressed against the left side of the security door, thereby enabling the horizontal plate to be more tightly and reliably connected to the left and right side walls of the security door.

[0011] The two levers have the first pivot point and the second pivot points, and the two levers have the first pivot point and the second pivot points respectively connected to the top of the two pivot points, the limit of each of the two pivot points being adjusted to one side and the limit of each of the two pivot points being adjusted to the left and right of the pivot points. When the two second baffles are in the same direction as the first baffles, the two second baffles will move to the left and the two second baffles will rotate in the direction of approaching each other until the two second baffles are perpendicular to the connecting plates. At this time, the passage between the two first vertical plates can be closed, and when the passage between the two first vertical plates is opened or closed, the two second baffles will move to the right or left, so that people can be prevented from leaving the passage between the two first vertical plates without having to deliberately step down and wait for the two second baffles to rotate in the direction of moving away from each other. At the same time, the two second baffles can be prevented from closing directly at a position close to the people and clamping their clothes or items, thereby improving the safety and reliability of the security inspection device.

[0012] Preferably, two groups of cross bars are symmetrically fixedly connected on the sides where the two first vertical plates are close to each other, and the two cross bars are symmetrically and movably connected to the sides where the two pairs of second vertical plates are far away from each other. Two groups of third elastic members are symmetrically fixedly connected between the two first vertical plates and the sides where the two pairs of second vertical plates are close to each other. The right ends of the two bottom plates are symmetrically fixedly connected to two rotating seats, and the two rotating seats are symmetrically rotatably connected to two rotating blocks through the third rotating rod and the third torsion spring. The right sides of the two rotating blocks are symmetrically fixedly connected to the left sides of the two connecting plates. The advantage of this arrangement is that when a person passes through the passage between the two first vertical plates, if he accidentally hits or touches the first When the second baffle is in contact with the first baffle, the second baffle and the first baffle will move forward and backward under the elastic force of the third elastic member, so that the bottom plate and the first vertical plate can be prevented from being directly impacted and moving, thereby preventing the left and right side walls of the security door and the horizontal plate from being damaged by a large force. At the same time, when a person collides or touches the second baffle when passing through the passage between the two second baffles, the two connecting plates will overcome the elastic force of the third torsion spring and rotate toward the front and back sides respectively, so that the impact force received by the second baffle can be prevented from being directly transmitted to the bottom plate, thereby improving the position stability of the bottom plate and preventing the left and right side walls of the security door and the horizontal plate from being damaged by a large force.

[0013] Preferably, a limiting assembly is also provided on the two base plates, and the limiting assembly is used to limit the two pairs of second vertical plates. The advantage of such a setting is that the two pairs of second vertical plates can be limited when transporting the movable base plate, thereby preventing the second vertical plates and the first baffle from moving, thereby facilitating the staff to move the transport base plate, and improving the convenience and practicality of the security inspection device.

[0014] Preferably, the limiting assembly includes two vertical cavities symmetrically opened on the tops of the two base plates, two blocking plates are symmetrically and movably plugged into the tops of the two vertical cavities, and two groups of fourth elastic members are symmetrically fixedly connected between the bottoms of the two blocking plates and the inner bottom walls of the two vertical cavities. The limiting assembly also includes a storage mechanism connected to the two base plates, and the storage mechanism is used to store the two blocking plates into the two vertical cavities. The advantage of this arrangement is that by storing the blocking plates into the two vertical cavities through the storage mechanism, the two pairs of second vertical plates and the two first baffles can be in a state where they can move freely. When the blocking plates move upward out of the vertical cavities, the two pairs of second vertical plates and the two first baffles can be limited to prevent them from moving freely, thereby facilitating the staff to carry and move the base plate.

[0015] Preferably, the storage mechanism includes two pairs of second electric push rods symmetrically fixedly connected on the adjacent sides of the two pairs of first vertical plates, two pressure plates symmetrically fixedly connected between the output ends of the two pairs of second electric push rods, two groups of fifth elastic members symmetrically fixedly connected between the sides of the two pressure plates that are away from each other and the sides of the two pairs of first vertical plates that are close to each other, and two rollers symmetrically connected to the right sides of the two pressure plates for rotation, and the outer peripheral surfaces of the two rollers can be tightly pressed against the sides of the two pressure plates that are away from each other, respectively. The advantage of this arrangement is that the staff presses the blocking plate downward into the vertical cavity, and then starts the second electric push rod to push the two pressure plates in the direction of approaching each other until the two pressure plates are respectively located on the top of the two blocking plates, at which time the blocking plate can be stored in the vertical cavity.

[0016] Compared with the prior art, the present invention has the following beneficial effects: The present invention can form a closed space behind the security door through two first vertical plates, two bottom plates, a connecting component, a first pass component and a second pass component. When the security door detects that the person passing through may be carrying prohibited items, the second pass component will not open the passage. At this time, the staff needs to manually control the second pass component to open the passage cavity to allow the person to leave. This can prevent security personnel from missing the alarm signal of the security door and causing people who may be carrying prohibited items to enter the construction site, effectively improving the reliability and practicality of the security inspection device.

DETAILED DESCRIPTION

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] See also Figures 1-11 The figure shows a personnel security inspection device based on power grid field management, comprising: a security door 1 and two base plates 2; the left sides of the two base plates 2 are connected to the security door 1 via a connecting assembly 3; the tops of the two base plates 2 are symmetrically fixedly connected to two first vertical plates 21; the two first vertical plates 21 have two symmetrical through cavities 22 formed on the side faces away from each other; the two base plates 2 are connected to a first passage assembly 4 for allowing personnel carrying dangerous goods to pass through, and a second passage assembly 5 for allowing personnel not carrying dangerous goods to pass through; The first passage assembly 4 includes two pairs of second vertical plates 41 symmetrically connected to the tops of the two bottom plates 2. The tops of the first passage assembly 4 are symmetrically connected to two hollow tubes 42. The two hollow tubes 42 are located between the adjacent side surfaces of the two pairs of bottom plates 2. Two first baffles 43 are symmetrically fixedly sleeved on the outer circumferences of the two hollow tubes 42. The two through cavities 22 are respectively aligned with the two first baffles 43. The second passage assembly 5 includes two connecting plates 51 symmetrically connected to the two bottom plates 2 , and two second baffles 53 are symmetrically connected to the tops of the two connecting plates 51 via two rotating mechanisms 52 .

[0021] See Figure 6 and Figure 11 The first passage assembly 4 further includes a locking mechanism 44 symmetrically connected to the two base plates 2 , and the locking mechanism 44 is used to connect and lock the first baffle 43 to the second vertical plate 41 .

[0022] Specifically, the first baffle 43 can be locked and connected to the second vertical plate 41 through the locking mechanism 44, so as to ensure that the first baffle 43 can block the passage between the two pairs of second vertical plates 41 when needed, so that people can leave through the passage between the two pairs of second vertical plates 41 only with the consent of the staff.

[0023] See Figure 6 and Figure 11 The locking mechanism 44 includes a straight rod 441 movably plugged into the top end of the hollow tube 42. The top end of the hollow tube 42 is provided with a plurality of limiting grooves in an annular shape with equal angles. The outer circumference of the straight rod 441 is fixedly connected with a plurality of limiting strips 442 in an annular shape with equal angles. The plurality of limiting strips 442 are respectively slidably connected in the plurality of limiting grooves. The top end of the straight rod 441 is fixedly connected with a grip rod 443. The locking mechanism 44 also includes a first transverse groove 444 provided on the left side of the first baffle 43. The left end of the first transverse groove 444 is connected to the inner hole of the hollow tube 42. A fixed rod 443 is slidably connected in the first transverse groove 444. Plate 445, a pull rope 446 is fixedly connected to the left side of the fixed plate 445, and the end of the pull rope 446 away from the fixed plate 445 passes through the first transverse groove 444 and the inner hole of the hollow tube 42 and is fixedly connected to the bottom end of the straight rod 441, and the right side of the fixed plate 445 is fixedly connected to the insertion rod 447, and two slots are symmetrically provided on the left side of the second vertical plate 41 on the right, and the right end of the insertion rod 447 passes through the right side wall of the first baffle 43 and is movably inserted into the inside of the slot, and a first elastic member 448 is fixedly connected between the right side of the fixed plate 445 and the right inner wall of the first transverse groove 444.

[0024] Specifically, the staff only needs to hold the handle 443 and pull the straight rod 441 upwards. The straight rod 441 overcomes the elastic force of the first elastic member 448 through the pull rope 446 and pulls the fixed plate 445 to move to the left. Then the fixed plate 445 pulls the insertion rod 447 out of the slot. Then the staff rotates the handle 443 to drive the first baffle 43 to rotate until the passage between the two pairs of second vertical plates 41 is opened to allow people who may be carrying prohibited items to come out.

[0025] See Figure 1 、 Figure 2 、 Figure 3 、 Figure 5 and Figure 10The connecting assembly 3 includes two straight plates 31 symmetrically fixedly connected to the left sides of the two bottom plates 2. Two horizontal plates 32 are symmetrically fixedly connected to the left sides of the two straight plates 31. Two card slots 33 are symmetrically opened on the left sides of the two horizontal plates 32. The two card slots 33 are symmetrically sleeved on the left and right side walls of the security door 1. Two mounting slots 34 are symmetrically opened on the front and rear inner side walls of the card slots 33. Two moving blocks 35 are symmetrically connected in the two mounting slots 34. Two receiving slots 36 are symmetrically opened on the right sides of the two moving blocks 35. The adjacent inner side walls respectively penetrate the adjacent side walls of the two moving blocks 35, and the two limiting plates 37 are symmetrically connected to the inner top wall and the inner bottom wall of the two accommodating grooves 36 through the first rotating rod and the first torsion spring. Two screws 38 are symmetrically threaded on the left sides of the two moving blocks 35, and the right ends of the two screws 38 penetrate the left sides of the two moving blocks 35 and extend into the two accommodating grooves 36. The right ends of the two screws 38 can be tightly pressed against the side surfaces of the two limiting plates 37, and the left ends of the two screws 38 penetrate the left side wall of the horizontal plate 32.

[0026] Specifically, when connecting the two bottom plates 2 and the security door 1, it is only necessary to align the two slots 33 with the left and right side walls of the security door 1 and then push the two bottom plates 2 to the left until the slots 33 are completely sleeved on the left and right side walls of the security door 1. As the slots 33 are gradually sleeved on the left and right side walls of the security door 1, the two limit plates 37 will rotate into the installation slots 34. When the slots 33 are completely sleeved on the left and right side walls of the security door 1, the two limit plates 37 will rotate into the installation slots 34. Under the action of the elastic force of the spring, it will rotate out of the mounting groove 34 and be located on the left side of the security door 1, so that the cross plate 32 can be firmly connected to the security door 1. When the security door 1 and the cross plate 32 need to be disassembled and separated, it is only necessary to rotate the screw 38 to the left until the right end of the screw 38 is pulled out of the receiving groove 36, and then pull the bottom plate 2 to the right. At this time, the limit plate 37 will rotate to the left into the receiving groove 36, thereby ensuring that the cross plate 32 can be smoothly separated from the security door 1.

[0027] See Figure 10 The connecting assembly 3 further includes a second elastic member 39 fixedly connected between the left side surface of the moving block 35 and the left inner wall of the mounting groove 34 .

[0028] Specifically, under the elastic force of the second elastic member 39 , the right side of the limit plate 37 can be pressed tightly against the left side of the security door 1 , so that the horizontal plate 32 can be more tightly and reliably connected to the left and right side walls of the security door 1 .

[0029] See Figure 1 、 Figure 2 and Figure 8The rotating mechanism 52 includes two rectangular cavities 521 symmetrically opened on the top of the two connecting plates 51, two pairs of guide rods 522 are symmetrically fixedly connected between the left and right inner walls of the two rectangular cavities 521, and two rectangular blocks 523 are symmetrically and movably connected between the outer circumferences of the two pairs of guide rods 522. The two second baffles 53 are symmetrically rotatably connected to the tops of the two rectangular blocks 523 through two first rotating shafts, and two first electric push rods 524 are symmetrically fixedly connected between the right sides of the two rectangular blocks 523 and the right inner wall of the rectangular cavity 521. Two driving wheels 525 are symmetrically fixedly connected on the outer circumferences of the two first rotating shafts. The rotating mechanism 52 also includes two driving plates 526 symmetrically fixedly connected to the tops of the two connecting plates 51. The two driving plates 526 are respectively located on the front and rear sides of the two driving wheels 525 and are tightly against the outer circumferences of the two driving wheels 525.

[0030] Specifically, the first electric push rod 524 is started to drive the two rectangular blocks 523 to move to the right, and the two rectangular blocks 523 drive the two driving wheels 525 and the two second baffles 53 to move to the right. At this time, the driving wheels 525, driven by the two driving plates 526, drive the two second baffles 53 to rotate in the direction away from each other through the first rotating shaft until the two second baffles 53 are respectively parallel to the two connecting plates 51. At this time, the passage between the two first vertical plates 21 is opened, which is convenient for people carrying contraband to leave. Conversely, when the first electric push rod 524 drives the two rectangular blocks 523 to move to the left, the two rectangular blocks 523 drive the two second baffles 53 to move to the left and At this time, the two second baffles 53 rotate in the direction of approaching each other until the second baffles 53 are perpendicular to the connecting plate 51. At this time, the passage between the two first vertical plates 21 can be closed, and when the passage between the two first vertical plates 21 is opened or closed, the two second baffles 53 will move to the right or left. This can prevent people from leaving the passage between the two first vertical plates 21 without having to deliberately step down and wait for the two second baffles 53 to rotate in the direction of moving away from each other. At the same time, it can prevent the two second baffles 53 from closing directly at a position close to the people and clamping their clothes or items, thereby improving the safety and reliability of the security inspection device.

[0031] See Figure 2 、 Figure 3 , pictures and Figure 9Two groups of cross bars 6 are symmetrically fixedly connected on the adjacent sides of the two first vertical plates 21, and the two cross bars 6 are symmetrically and movably inserted on the adjacent sides of the two pairs of second vertical plates 41. Two groups of third elastic members 61 are symmetrically fixedly connected between the adjacent sides of the two first vertical plates 21 and the two pairs of second vertical plates 41. Two rotating seats are symmetrically fixedly connected to the right ends of the two bottom plates 2. Two rotating blocks 62 are symmetrically rotatably connected to the two rotating seats through the third rotating rod and the third torsion spring. The right sides of the two rotating blocks 62 are symmetrically fixedly connected to the left sides of the two connecting plates 51.

[0032] Specifically, when a person passes through the passage between the two first vertical plates 21 and accidentally collides with or touches the second vertical plate 41 and the first baffle 43, the second vertical plate 41 and the first baffle 43 will move forward and backward under the elastic force of the third elastic member 61, thereby preventing the bottom plate 2 and the first vertical plate 21 from being directly impacted and moving, thereby preventing a large force from being generated between the left and right side walls of the security door 1 and the horizontal plate 32 and causing damage. At the same time, when a person collides with or touches the second baffle 53 when passing through the passage between the two second baffles 53, the two connecting plates 51 will overcome the elastic force of the third torsion spring and rotate toward the front and rear sides respectively, thereby preventing the impact force on the second baffle 53 from being directly transmitted to the bottom plate 2, thereby improving the position stability of the bottom plate 2 and preventing a large force from being generated between the left and right side walls of the security door 1 and the horizontal plate 32 and causing damage.

[0033] See Figure 3 、 Figure 4 and Figure 9 A limiting assembly 7 is further provided on the two bottom plates 2 , and the limiting assembly 7 is used to limit the two pairs of second vertical plates 41 .

[0034] Specifically, the two pairs of second vertical plates 41 can be limited when transporting the movable base plate 2, thereby preventing the second vertical plates 41 and the first baffles 43 from moving, thereby facilitating the movement of the transport base plate 2 by the staff, and improving the convenience and practicality of the security inspection device.

[0035] See Figure 4 and Figure 9 The limiting assembly 7 includes two vertical cavities symmetrically opened on the top of the two bottom plates 2, and two blocking plates 71 are symmetrically and movably inserted at the top of the two vertical cavities. Two groups of fourth elastic members are symmetrically fixedly connected between the bottom of the two blocking plates 71 and the inner bottom walls of the two vertical cavities. The limiting assembly 7 also includes a storage mechanism 72 connected to the two bottom plates 2, and the storage mechanism 72 is used to store the two blocking plates 71 into the two vertical cavities.

[0036] Specifically, by storing the blocking plate 71 in the two vertical cavities through the storage mechanism 72, the two pairs of second vertical plates 41 and the two first baffles 43 can be in a state where they can move freely. When the blocking plate 71 moves upward out of the vertical cavity, the two pairs of second vertical plates 41 and the two first baffles 43 can be limited to prevent them from moving freely, thereby facilitating the staff to carry the mobile base plate 2.

[0037] See Figure 4 and Figure 9 The storage mechanism 72 includes two pairs of second electric push rods 721 symmetrically fixedly connected to the adjacent sides of the two pairs of first vertical plates 21, two pressure plates 722 symmetrically fixedly connected between the output ends of the two pairs of second electric push rods 721, two groups of fifth elastic members symmetrically fixedly connected between the sides away from each other of the two pressure plates 722 and the sides close to the two pairs of first vertical plates 21, and two rollers 723 symmetrically connected to the right sides of the two pressure plates 722 for rotation, and the outer circumferential surfaces of the two rollers 723 can be tightly pressed against the sides away from each other of the two pressure plates 722.

[0038] Specifically, the staff presses the blocking plate 71 downward into the vertical cavity, and then starts the second electric push rod 721 to push the two pressure plates 722 toward each other until the two pressure plates 722 are respectively located on the top of the two blocking plates 71. At this time, the blocking plate 71 can be stored in the vertical cavity.

[0039] Working principle: When a person passes through the security gate 1 and is not detected as carrying any prohibited items, the first electric push rod 524 drives the two rectangular blocks 523 to move to the right, and the two rectangular blocks 523 drive the two driving wheels 525 and the two second baffles 53 to move to the right. At this time, the driving wheel 525, driven by the two driving plates 526, drives the two second baffles 53 to rotate in a direction away from each other through the first rotating shaft until the two second baffles 53 are respectively parallel to the two connecting plates 51. At this time, the passage between the two first vertical plates 21 is opened, making it convenient for people carrying prohibited items to leave.

[0040] When a person who does not carry prohibited items leaves the passage between the two first vertical plates 21, the first electric push rod 524 drives the two rectangular blocks 523 to move to the left, and the two rectangular blocks 523 drive the two second baffles 53 to move to the left. At this time, the two second baffles 53 rotate in a direction close to each other until the second baffles 53 are perpendicular to the connecting plate 51. At this time, the passage between the two first vertical plates 21 can be closed.

[0041] When a person is detected to be carrying prohibited items when passing through the security gate 1, the first electric push rod 524 will not start. At this time, the person cannot leave the passage between the two first vertical plates 21. This makes it easy for the staff to promptly discover people who may be carrying prohibited items. The staff then only needs to hold the grip 443 and pull the straight rod 441 upwards. The straight rod 441 overcomes the elastic force of the first elastic member 448 through the pull rope 446 and pulls the fixed plate 445 to move to the left. The fixed plate 445 then pulls the insertion rod 447 out of the slot. The staff then rotates the grip 443 to drive the first baffle 43 to rotate until the passage between the two pairs of second vertical plates 41 is opened to allow people who may be carrying prohibited items to come out. The person who may be carrying prohibited items can then be subject to a more detailed inspection to prevent prohibited items from being brought into the construction site.
