Description

Technical Field

[0001] The invention relates to the technical field of security door assembly, and in particular to a transversely spliced ​​portable detection door. Background Art

[0002] Detection gates, also known as security gates, are detection devices used to detect whether people are carrying metal or other prohibited items. They are mainly used in public places such as airports, stations, subways, and gymnasiums. When the person being inspected passes through the security gate, if the weight, quantity, or shape of the metal or prohibited items carried on the person's body exceeds the pre-set parameter value, the security gate will immediately issue a warning sound or flash a warning to alert the security personnel.

[0003] According to the national standard "GB 15210-2003 General Technical Specifications for Walk-Through Metal Detection Doors", the detection area and detection plane are defined in Sections 3.2 and 3.3 of the main text of the standard. According to the established rectangular three-dimensional coordinate system, the direction of passing through the detection area is set as the Y-axis direction, that is, the Z-axis direction is the height direction of the detection door, and the X-axis direction is the horizontal connection direction of the two detection door panels. The position direction of the detection door of the present invention is defined below according to the three-dimensional coordinate direction set in the standard, and the Y-axis direction passing through the detection door is set as the horizontal direction.

[0004] The traditional detection door includes two door leaves on the left and right, and a crossbeam is connected between the two door leaves. In order to adapt to different groups of people, the height of the detection door is usually high, and most of the detection doors are made of plastic materials. Therefore, when producing the detection door leaves, it is necessary to use a larger mold for production, and at the same time, it is necessary to cooperate with larger machinery and equipment compatible with the mold, which increases the production cost and occupies a larger space in the production chain. Due to the large size of the detection door, it is inconvenient to carry and transport it, and it occupies a larger transportation space.

[0005] The existing detection door has a sensor for detecting metal in the door leaf. The sensor is a combination of a large coil that emits electromagnetic signals and a small coil that receives electromagnetic wave signals. The electromagnetic waves emitted by the large coil return to the position of the small coil in a circular motion. When the electromagnetic wave signal emitted by the large coil senses a metal object, the small coil cannot receive the electromagnetic wave signal due to the shielding effect of the metal, and it is determined that there is metal in the object passing between the door leaves. Since the middle position between the two door leaves has the lowest sensitivity, the electromagnetic waves emitted by the two door leaves may not intersect with each other. When the metal is small and passes through the middle position of the two door leaves, the detection cannot detect the metal.

[0006] For example, when the distance between the two door leaves is set to be constant and the width of the large coil installed on the door leaf passing through the detection door is 350 mm to 400 mm, a one-yuan coin passing through the middle position between the two door leaves cannot be detected. Therefore, only when the large coil of the door leaf is widened and passes through the width of the detection door, the distance of the electromagnetic wave emitted by the large coil flying out of the door leaf can be increased, but the existing detection door is not provided with a structure that can widen the width of the door leaf.

The length direction of the slide bar 222 is consistent with the Z-axis direction, and the slide bar 222 and the upper and lower end surfaces of the widened plate 22 along the Z-axis direction are coplanarly arranged. The two vertical plates 21 of the combination plate 2 are respectively integrally connected with a slide groove 211 for sliding connection of the slide bar 222 and an assembly bar 212 slidably connected to the assembly groove 221 on the side facing the widened plate 22, and the assembly bar 212 is slidably adapted to the slide groove 211.

[0048] Reference Figures 3 to 7 As shown, the two vertical plates 21 are fixedly connected with a working strip 213 along one end passing through the detection door direction and away from the side of the widening plate 22. The working strip 213 extends along the Z-axis direction. The working strip 213 and the upper and lower end surfaces of the vertical plates 21 along the Z-axis direction are coplanarly arranged. The working strip 213 is slidably connected with a frame plate 23. The frame plate 23 is made of aluminum profile material. The frame plate 23 has two working grooves 231 on the side facing the working strip 213 for sliding connection with the working strip 213. The working groove 231 extends along the Z-axis direction. The working groove 231 is connected with the upper and lower end surfaces of the frame plate 23 along the Z-axis direction. The two groups of combined plates 2 and the two frame plates 23 are interconnected to form a door panel module 11 in the shape of a central through tube.

[0049] Reference Figures 3 to 8As shown, the vertical plate 21 and the widened plate 22 of the same combined plate 2 are arranged opposite to each other with the vertical plate 21 and the widened plate 22 of another combined plate 2, and the sides of the vertical plate 21 and the widened plate 22 of the same combined plate 2 opposite to each other are fixedly connected with a plurality of mounting grooves 214, the mounting grooves 214 extend along the Z-axis direction, and the mounting grooves 214 are respectively connected to the upper and lower end surfaces of the vertical plate 21 and the widened plate 22 along the Z-axis direction, and the plurality of mounting grooves 214 of the same combined plate 2 are slidably connected with the same mounting plate 3, and the side of the mounting plate 3 is fixedly connected with a plurality of mounting strips 31 slidably connected with the plurality of mounting grooves 214 of the same combined plate 2, the length of the mounting strip 31 along the Z-axis direction is less than the length of the mounting slot 214 along the Z-axis direction, there is a distance between the top end of the mounting strip 31 along the Z-axis direction and the top end of the mounting plate 3 along the Z-axis direction, there is a distance between the bottom end of the mounting strip 31 along the Z-axis direction and the bottom end of the mounting plate 3 along the Z-axis direction, and there is a distance between the mounting plates 3 of the two combined plates 2.

[0050] Specifically, by setting a group of door panel modules 11 and fixing parts 5, several door panel modules 11 of a group of door panel modules 11 can be spliced ​​along the Z-axis direction using the fixing parts 5. Since the size of the door panel module 11 can be formulated as multiple reference size standards as needed, and a related module library is formed thereby, it is beneficial to mass production of the door panel modules 11. Since the door panel modules 11 in the module library are divided into different models according to different sizes, and are small in size and light in weight, it is beneficial to reduce the size of the production mold of the production module, reduce costs, and reduce the production space occupied during production. At the same time, the multiple door panel modules 11 installed can reduce the packaging volume, transportation space and occupied space, and have the characteristics of convenient handling and transportation of the door panel modules 11. Since a group of door panel modules 11 contains multiple door panel modules 11 spliced ​​with each other, multiple door panel modules 11 can be spliced ​​in the vertical direction to form a specified height dimension, which is beneficial to improve the adjustment of the height dimension of a group of door panel modules 11 to improve the flexibility of assembly.

[0051] By setting up the combined board 2 and dividing the combined board 2 into the widened board 22 and the vertical board 21, it is helpful to further reduce the combined unit of the door panel module 11, and then reduce the size of the production mold for producing the widened board 22 and the vertical board 21 that constitute the combined board 2, and the size of the machine for producing and processing extrusion and plastic will also be reduced accordingly. The door panel module 11 can reduce the cost of developing molds and make the production and manufacturing more modular and intelligent due to the splicing combination of the module units such as the widened board 22 and the vertical board 21. At the same time, it is convenient to produce in a smaller production space. Since the unit module product is small, it is helpful to improve production efficiency and increase production capacity. At the same time, a group of door panel modules 11 is divided into multiple small units for splicing. When one of the parts in the detection door is damaged, only the corresponding damaged part needs to be replaced, and the entire detection door does not need to be replaced, so that the maintenance of the detection door is simple and the maintenance cost is saved.

[0052] By providing the skeleton plate 23, two independent assembly plates can be connected to form the overall structure of the door panel module 11, which helps to reduce the separation of the assembly plates 2 of the same door panel module 11, thereby improving the stability of the overall structure of the door panel module 11.

[0053] Reference Figures 3 to 6 As shown, a plurality of positioning posts 32 are threadedly connected between the two mounting plates 3. The positioning posts 32 are plastic screws, and the screws of the plastic screws penetrate the two mounting plates 3 facing each other. The plurality of positioning posts 32 are distributed around the plane of the mounting plates 3. A large coil 33 for transmitting electromagnetic wave signals is fixed around the plurality of positioning posts 32. The large coil 33 is located between the two mounting plates 3. The large coil 33 abuts against the side of the mounting plate 3 facing the other group of door panel modules 11. The large coil 33 is tied and fixed to the mounting plate 3 away from the other group of door panel modules 11 by a cable tie to improve the stability of the installation of the large coil 33.

[0054] Reference Figures 3 to 6 As shown, the mounting plate 3 far away from another group of door panel modules 11 is fixedly connected with a number of small coils 34 receiving electromagnetic wave feedback signals, and the several small coils 34 are all located in the large coil 33. The several small coils 34 in the large coil 33 are evenly spaced along the Z-axis direction. The side of the mounting plate 3 far away from the detection door channel and close to the large coil 33 is coated with a graphite layer for shielding interference signals. The mounting plate 3 is located inside the small coil 34 and is installed with a shielding wire 35 for shielding circuit signals along the Z-axis direction. One end of the shielding wire 35 is connected to the small coil 34, and the other end is connected to the ground.

[0055] Specifically, by setting the mounting plate 3 and the positioning column 32, a large coil 33 for emitting electromagnetic wave signals is installed, and a small coil 34 for receiving electromagnetic wave feedback signals is set in the large coil 33 of the mounting plate 3, which is conducive to improving the principle of using the large coils 33 of the two sets of door panel modules 11 to emit electromagnetic wave signals to the detection door channel, and using the small coil 34 to receive electromagnetic wave signals to determine whether there is metal passing through the middle of the detection door, which is conducive to detecting the weakest signal in the detection area in the middle of the door channel, and the electromagnetic waves emitted by the two sets of door panel modules 11 do not overlap. Therefore, the overlapping range of the electromagnetic waves emitted by the two sets of door panel modules 11 is The circumference increases with the increase of the width of the large coil 33 along the direction of passing through the detection door (Y-axis direction), so the combined plate 2 of the door panel module 11 is divided into a vertical plate 21 and a widened plate 22. When the width of the door panel module 11 along the Y-axis direction needs to be increased, the number of widened plates 22 can be increased, and the mounting plates 3 with a larger width dimension in the Y-axis direction are replaced in several installations of the combined plate 2 to replace the larger large coil 33, thereby increasing the overlap range of the electromagnetic wave signals emitted by the two groups of door panel modules 11 and reducing the situation where metal with a smaller volume passes through the middle position between the two groups of door panel modules 11, so as to improve the sensitivity of the detection door in detecting metal.

[0056] The graphite layer is provided to reduce the situation that the electromagnetic wave of the mounting plate 3 is transmitted to the outside of the detection door and generates interference in the detection of metal, and at the same time, it is helpful to reduce the situation that the external interference signal passes through the mounting plate 3 to interfere with the electromagnetic wave signal of the large coil 33, or is transmitted to the small coil 34 and generates interference. By providing a shielding wire 35 in the small coil 34, the electromagnetic wave signal received by the small coil 34 is transmitted to the ground, so that the small coil 34 can receive the signal next time, and reduce the situation that the redundant electromagnetic wave signal in the small coil 34 accumulates and generates interference.

[0057] Reference Figures 3 to 8As shown, a connecting plate 24 is inserted into the top surface of the door panel module 11 along the Z-axis direction, and flanges 241 for inserting and limiting the door panel module 11 are raised at both ends of the outer peripheral surface of the connecting plate 24 along the Z-axis direction, and the splicing plate 242 is divided into a splicing plate 242 and two end plates 243 along the Y-axis direction, that is, the connecting plate 24 includes a splicing plate 242 and two end plates 243, and the two end plates 243 are located at both ends of the top surface of the door panel module 11 along the Y-axis direction, and the splicing plate 242 is located between the two end plates 243, and the splicing plate 242 and the end plates 243 abut against each other. After the external nut thread passes through the splicing plate 242 and the two end plates 243 of the connecting plate 24, the external nut is threadedly connected to the top of the mounting groove 214 of the vertical plate 21 and the widened plate 22 of the combined plate 2 along the Z-axis direction, and the external nut abuts against the top of the mounting strip 31 of the mounting plate 3 along the Z-axis direction. At the same time, after the external nut passes through the two end plates 243 of the connecting plate 24, the external nut is threadedly connected to the top end of the frame plate 23 along the Z-axis direction. After the screw passes through the connecting plate 24, the screw is threadedly connected to the external nuts in the mounting grooves 214 of the frame plate 23 and the combination plate 2 respectively, and the nut of the screw presses the connecting plate 24 to cover the mounting plate 3 of the door panel module 11.

[0058] Specifically, by providing a flange 241 for plugging the door panel module 11 on the connecting plate 24, when the number of door panel modules 11 in a group is greater than one, and connecting adjacent door panel modules 11 in a group of door panel modules 11, the installation misalignment of adjacent door panel modules 11 is reduced, and the stability of the splicing structure of adjacent door panel modules 11 in the same group of door panel modules 11 is improved. By dividing the connecting plate 24 into a splicing plate 242 and two end plates 243, while splicing a plurality of vertical plates 21 along the Y-axis direction, the number of splicing plates 242 can be increased or decreased according to the splicing size to achieve the length dimension of the connecting plate 24 along the Y-axis direction. At the same time, the installation splicing of the connecting plate 24 is split into a plurality of splicing plates 242 and end plates 243 along the Y-axis direction with the splicing of the door panel modules 11, so as to realize modular production, which is conducive to reducing the size of the production mold and saving costs. At the same time, the specified size requirements can be achieved through splicing, and the flexibility of installation splicing is improved.

[0059] Reference Figures 3 to 8As shown, a light-emitting member 4 for generating light is arranged between the two combination plates 2, and the light-emitting member 4 is a light bar 41. A slot 232 is provided on the side of the skeleton plate 23 away from the two combination plates 2, and the slot 232 extends along the Z-axis direction. The slot 232 is connected to the upper and lower end surfaces of the skeleton plate 23 along the Z-axis direction. The slot 232 is slidably connected with a lampshade 42, and a lamp groove 233 is provided on the bottom surface of the slot 232, and the lamp groove 233 extends along the Z-axis direction. The lamp groove 233 is connected to the upper and lower end surfaces of the skeleton plate 23 along the Z-axis direction. The light bar 41 is slidably connected to the lamp groove 233, and the light projection end of the light bar 41 is arranged toward the lampshade 42, and the lampshade 42 is made of a light-guiding PVC plastic material with uniform light.

[0060] Specifically, by arranging a lampshade 42 in the card slot 232 and arranging a light bar 41 in the light slot 233, since the lampshade 42 is made of a light-guiding PVC material with uniform light properties, when it is detected that the object passing through the detection door contains contraband such as metal, the light bar 41 is used to emit light, so that the light tube is transmitted on the lampshade 42, and the light-uniformity and light-guiding effects of the lampshade 42 are used to make the lampshade 42 illuminate. At the same time, the opening and closing control of the light bars 41 of the adjacent door panel modules 11 are all controlled by the small coil 34 of the door panel module 11, so that the light of the light bars 41 of the adjacent door panel modules 11 is independent of each other. When the large coil 33 and the small coil 34 of a certain door panel module 11 along the Z-axis direction detect that the object passing through the detection door contains contraband such as metal, the small coil 34 of the door panel module 11 controls the light bar 41 of the door panel module 11 to emit light, so as to indicate the specific range of the object passing through the detection door, which is conducive to shortening the time for the case personnel to search.

The two side plates 252 are arranged on both sides of the door panel module 11 along the Y-axis direction, and the intermediate plate 251 is located between the two door panel modules 11. The intermediate plate 251 and the side plates 252 abut against each other, and the intersection where the intermediate plate 251 and the side plates 252 are connected is opposite to the vertical plate 21, and the intersection where the widened plate 22 and the vertical plate 21 are connected is opposite to the intermediate plate 251. After the external nut passes through the sealing plate 25, the external nut is threadedly connected to the bottom end of the mounting groove 214 of the vertical plate 21 and the widened plate 22 along the Z-axis direction. After the screw passes through the sealing plate 25, the screw is threadedly connected to the external nut at the bottom end of the mounting groove 214 along the Z-axis direction, and the nut of the screw presses the sealing plate 25.

[0062] Specifically, by providing the sealing plate 25, it is convenient for the external nut and the screw to lock and connect the sealing plate 25 with the door panel module 11, so that the sealing plate 25 presses the mounting plate 3, which is beneficial to improving the stability of the mounting plate 3 installation, and reducing the separation of the sealing plate 25 and the door panel module 11. Since the sealing plate 25 is divided into the middle plate 251 and the side plate 252, and the middle plate 251 and the side plate 252 of the sealing plate 25 are installed in a staggered arrangement with the splicing plate 242 and the end plate 243 of the connecting plate 24, when the sealing plate 25 is connected to the combined plate 2, the middle plate 251 presses the intersection between the splicing plate 242 and the side plate 252, which is beneficial to improving the installation stability of the connecting plate 24 and the sealing plate 25.

[0063] Reference Figures 6 to 12 As shown, a slot 234 is vertically penetrated on the top surface of the skeleton plate 23 along the Z-axis direction, and the slots 234 of several door panel modules 11 spliced ​​with each other through the connecting plate 24 in the same group of door panel modules 11 are opposite to each other.

[0065] Reference Figures 6 to 13As shown, the same group of door panel modules 11 is installed with fixing parts 5 for fixing several door panel modules 11, and the fixing parts 5 include a light rod 51 which is plugged into straight holes 261 which are opposite to several positioning strips 26, and one end of the light rod 51 is threadedly connected to a fixing block 262 of the positioning strip 26 at the bottom, and one end of the light rod 51 away from the fixing block 262 is threadedly connected to a clamping block 52 for clamping several door panel modules 11, and the clamping block 52 is a hand screw.

[0066] Specifically, by setting a slot 234 to facilitate the insertion of the same positioning strip 26 into several interconnected door panel modules 11, it is beneficial to improve the guidance of the jointing of several door panel modules 11. By setting two screw holes 263 on the side of the positioning strip 26, and setting a circular hole (as shown in the figure) on the bottom surface of the groove of the slide groove 211 of the skeleton plate 23, it is convenient for the screw to pass through the circular hole (as shown in the figure) and then be threadedly connected with the screw hole 263, so that the several door panel modules 11 on the positioning strip 26 form a unit, and the positioning strip 26 protrudes from the top of the unit for another unit to be plugged in, thereby achieving the effect of finishing and interconnecting, and improving the installation stability. By setting a straight hole 261 at the top of the positioning strip 26, it is convenient to insert the light rod 51 into the straight holes 261 facing each other in several door panel modules 11 of a group of door panel modules 11, and by setting a fixing block 262 at the top of the straight hole 261 of the positioning strip 26 at the top of a group of door panel modules 11, one end of the light rod 51 is connected to the fixing block 262, and the clamping block 52 is threadedly connected to the end of the light rod 51 away from the fixing block 262. As the number of threaded engaging teeth of the clamping block 52 and the light rod 51 increases, the distance between the clamping block 52 and the fixing block 262 is reduced, so as to clamp several interconnected door panel modules 11 in a group of door panel modules 11, thereby improving the stability of the connection between several door panel modules 11 in a group of door panel modules 11.

[0069] Specifically, by setting the door head assembly 6 to connect the two sets of door panel modules 11, an integral detection door structure is formed. By dividing the door head panel 7 into two door head panel groups 71, and dividing the door head panel group 71 into a middle plate 711 and an edge plate 714, the door head panel 7 is divided into a number of smaller units, which is conducive to reducing the size of the production mold, saving production costs, and reducing the transportation space and handling space of the product, so as to facilitate batch production. Due to the smaller parts, the production time can be shortened and the production efficiency can be improved. By setting the plug-in board 72, the two plug-in boards 72 and the two door head panel groups 71 form the overall structure of the door head panel 7 in a centrally arranged manner, and the door head panel 7 is divided into a number of parts, which is conducive to reducing the size of the parts constituting the door head panel 7, thereby reducing the size of the production mold and saving production space. At the same time, when some parts in the door head panel 7 are damaged, the corresponding parts can be replaced according to demand without replacing the overall structure, so that the maintenance operation of the door head assembly 6 is simple.

The two side section plates 742 are arranged on both sides of the door head plate 7 along the Y-axis direction. The middle section plate 741 is located between the two side section plates 742. The middle section plate 741 and the side section plates 742 are abutted against each other. After the external thread nut passes through the middle section plate 741 and the side section plate 742 of the bottom plate 74, it is assembled with the door head. The connecting groove 718 of the middle plate 711 and the edge plate 714 of the plate 71 is threadedly connected at the bottom end along the Z-axis direction. After the screw passes through the middle section plate 741 and the side section plate 742 of the bottom plate 74, it is threadedly connected with the external nut at the bottom end of the door head assembly plate 71 along the Z-axis direction, and the nut of the screw presses the bottom plate 74, and the intersection of the connection between the middle section plate 741 and the side section plate 742 is arranged to face the bottom surface of the edge plate 714 along the Z-axis direction.

[0072] Specifically, by providing the top plate 73 and the insert edge 731, the door head plate 7 composed of the middle plate 711 and the edge plate 714 is inserted into the insert edge 731 of the top plate 73, which is conducive to reducing the separation of the middle plate 711 and the edge plate 714 of the door head plate 7, so as to improve the stability of the overall structure of the door head plate 7, and by locking and connecting the top plate 73 and the door head plate 7 with external nuts and screws, the overall stability of the door head plate 7 and the top plate 73 is further improved. By providing the middle plate 732 and the side plate 733, the top plate 73 is composed of smaller parts, which is conducive to reducing the volume of the production mold and saving production costs. By providing the bottom plate 74 and dividing the bottom plate 74 into the middle section plate 741 and the side section plate 742, it is conducive to reducing the size of the production mold, saving costs, and reducing the handling and transportation space.

[0073] Reference Figures 14 to 16As shown, the insert edge 731 of the top plate 73 is plugged with a clamping plate 75, and the clamping plate 75 is divided into a plurality of lower pressing plates 751 that abut against each other along the Y-axis direction, and the intersection between adjacent lower pressing plates 751 is arranged opposite to the top surface of the side plate 733. The plug-in plate 72 and the skeleton plate 23 are arranged opposite to each other along the Z-axis direction, and the top of the plug-in plate 72 along the Z-axis direction is penetrated with a plug-in hole 722, and the plug-in hole 722 is plugged with a residual bone bar 76, which is made of aluminum material, and the structure of the residual bone bar 76 is similar to that of the positioning bar 26, and the top surface of the residual bone bar 76 along the Z-axis direction is penetrated with a plug-in hole 761 that is opposite to the straight hole 261 of the positioning bar 26, and the light rod 51 is plugged with the plug-in hole 761, and the end of the light rod 51 away from the fixing block 262 protrudes from the top of the clamping plate 75. The screw rod of the hand screw of the clamping block 52 passes through a pad 53. When the hand screw is threadedly connected to the threaded hole 513 of the connecting rod 511 at the top of the light rod 51 along the Z-axis direction, the pad 53 and the clamping plate 75 are pressed against each other. The hand screw is used to press the pad 53 and the clamping plate 75 at the same time. As the number of thread engagements between the hand screw and the threaded hole 513 of the connecting rod 511 increases, the distance between the hand screw and the fixing block 262 is shortened, so as to compress a number of door panel modules 11 and door head panels 7 spliced ​​to each other along the Z-axis direction.

[0074] Reference Figures 14 to 16 As shown, two connecting beams 77 arranged parallel to each other are fixed between the two door head panels 7 by screws, and the two connecting beams 77 are arranged on both sides of the door head panels 7 along the Y-axis direction, and one of the connecting beams 77 is installed with an image recognition device 771. A support foot 8 (such as Figure 1 shown).

[0075] Specifically, by setting a pressing plate 75 composed of a plurality of pressing plates 271, inserting a residual bone strip 76 in the door head plate 7, and using the light rod 51 to pass through the insertion hole 761 of the residual bone strip 76 and then insert it into the positioning strip 26 of the door panel module 11, the light rod 51 is threadedly connected with the fixing block 262. As the number of threads of the hand screw and the connecting rod 511 of the light rod 51 increases, the distance between the nut of the hand screw and the top of the light rod 51 decreases, thereby connecting and pressing the door head plate 7 and a plurality of door head modules connected by the positioning strip 26, which is conducive to improving the stability of the connection between the door panel module 11 and the door head assembly 6. By setting a connecting beam 77, the two groups of door panel modules 11 are connected by the connecting beam 77, so that the two groups of door panel modules 11 form an integral integrated structure. By setting an identification device 771, the image recognition function of the identification device 771 is used to determine whether the appearance of the door detected is a prohibited item, reduce the situation of missed inspection in security inspection, and improve the recognition of security inspection.

[0076] More specifically, see Figure 21 to Figure 23As shown, the widened width between the two vertical plates 21 of the door panel module 111 is increased or the number is increased, so that the width of the door panel module 111 along the direction of passing through the detection door (Y-axis direction) is increased, so that the width of the detection door in the direction of passing through the detection door can be adjusted according to needs, and installed on the mounting plate 3, large coil 33 and small coil 34 with mutually adapted sizes.

[0077] Under the premise that the sizes of the large coil 33 and the small coil 34 remain unchanged, since the height of the door panel module 111 along the Z-axis direction increases as the number of small coils 34 in the door panel module 111 increases, for example, the following settings are made:

[0078] 1. A door panel module 111 with a large coil 33 and a small coil 34 installed, and a height of 300 mm to 400 mm, is set as A;

[0079] 2. A door panel module 111 with a large coil 33 and two small coils 34 installed, and a size height of 600 mm to 800 mm, is set to be named B;

[0081] 4. A door panel module 111 with a large coil 33 and four small coils 34 installed, and a size height of 1200 mm to 1600 mm, is set to D;

[0082] 5. A door panel module 111 with a large coil 33 and five small coils 34 installed, and a size height of 1500 mm to 2000 mm, is set to be named E;

[0083] 6. Set the door head assembly 6, and the size height is 200 mm to 250 mm, and set the name to F;

[0084] 7. Set the name of support foot 8 to G;

[0085] 8. An integrated unit formed by connecting two door panel modules 111 with a height of 300 mm to 400 mm with the same positioning strip 26 is named AA; and the same applies to the following.

[0086] According to the above-mentioned number of small coils 34 in the door panel module 111 and the integrated unit composed of several door panel modules 111 formed by the positioning strips 26, the combination arrangement forms of the integrated unit composed of the door panel modules 111 and the door head assembly 6 along the Z-axis direction of the several door panel modules 111 in the door leaf 1 of the security door are as follows: 1. A+A+A+A+A+A+F+G; 2. AA+AA+AA+F+G; 3. AAA+AAA+F+G; 4. AA+B+B+F+G; 5. B+B+B+F+G; 6. C+C+F+G; 7. AAAA+B+F+G; 8. AAA+C+F+G; 9. AA+AA+B+F+G.

[0087] In summary, by providing a door panel module 11 composed of two combined panels 2, and since the combined panel 2 is composed of a vertical panel 21 and a widened panel 22, it is beneficial to reduce the size of the production mold of the production module, reduce costs, and reduce the production space occupied during production; at the same time, the multiple door panel modules 11 installed can reduce the packaging volume, reduce the transportation space and occupied space, and have the characteristics of convenient handling and transportation of the door panel module 11; at the same time, the combined panel 2 is composed of two vertical panels 21 located at the ends and a number of widened panels 22 located between the two vertical panels 21, which is convenient for widening the width of the combined panel 2 along the direction of passing through the detection door, and then widening the width of the door panel module 11 along the direction of passing through the detection door, so as to facilitate the installation of a mounting plate 3 with a larger width in the direction of passing through the detection door in the door panel module 11, and facilitate the installation of a large coil 33 with a larger width. When the large coil 33 is fully When the body size is large, the width along the direction of passing through the detection door is increased at the same time, so that the distance of the electromagnetic wave signal emitted by the large coil 33 is farther, and the distance between the two groups of door panel modules 11 remains unchanged, which is beneficial to increase the overlapping range of the electromagnetic wave signals emitted by the two groups of door panel modules 11, so that metal contraband passing through the middle of the detection door can be detected, thereby improving the sensitivity of the large coil 33 and the small coil 34 in detecting metal contraband; by setting a fixing part 5, a plurality of door panel modules 11 of a group of door panel modules 11 are fixed to improve the stability of the overall structure of a group of door panel modules 11, and by setting a light-emitting part 4, the door panel module 11 will generate a light-emitting alarm prompt when a metal contraband is detected to alert the security personnel; by setting a door head assembly 6, the two groups of door panel modules 11 are connected, which is beneficial to improve and then form an overall detection door structure.

[0088] Embodiment 2:

[0089] The difference between Example 2 and Example 1 is that:

[0090] Reference Figures 17 to 20As shown, an alarm light-emitting member 4 is arranged between the two combined panels 2, and the light-emitting member 4 includes a light board 43 connected to the top surface of the connecting plate 24 away from the door panel module 11 by screws. The light board 43 is divided into a number of light-emitting panels 431 along the Y-axis direction, and the intersection of the connection between adjacent light-emitting panels 431 is arranged opposite to the splicing plate 242 and the pressure plate 271. A number of lamp beads 432 are installed on the light board 43, and the connecting plate 24 is penetrated with a number of through holes 244 for the lamp beads 432 to pass through. The number of through holes 244 and the top surfaces of the vertical plate 21 and the widened plate 22 along the Z-axis direction are opposite to each other. The vertical plate 21 and the widened plate 22 are made of light-conducting materials with uniform light. The opening and closing of the light board 43 is controlled by the large coil 33 and the small coil 34. When the small coil 34 does not receive the electromagnetic wave signal, the existing power supply control circuit is controlled to make the light board 43 light up.

[0091] Reference Figures 17 to 20 As shown, in the same door panel module 11, the light board 43 is installed with a cover plate 27 plugged into the flange 241 of the connecting plate 24 on the top plate 73 away from the connecting plate 24, and the cover plate 27 includes a plurality of top pressure plates 271 arranged along the direction of passing through the detection door (Y-axis direction), and the intersections between adjacent top pressure plates 271 are arranged opposite to the light-emitting board 431, and the light board 43 and the cover plate 27 are both penetrated by plug-in grooves 272 for the positioning strip 26 to be plugged in and limited.

[0092] Specifically, by setting a light board 43 on the top surface of the door panel module 11, since the vertical plate 21, the widened plate 22 and the frame plate 23 are made of a light-conducting material with uniform light, and the light ball 781 of the light board 43 is arranged opposite to the top surfaces of the vertical plate 21, the widened plate 22 and the frame plate 23, when the light ball 781 of the light board 43 is lit, the door panel module 11 is illuminated as a whole, so that the security inspector can better observe and remind the case personnel. At the same time, the small coils 34 between the door panel modules 11 are independent of each other. Under the control of the circuit, the small coils 34 control the opening and closing of the light panel 43 of the door panel module 11. When there are contraband such as metal at a certain height position through the detection door, the large coils 33 and the large coils 33 at the corresponding height position will detect the contraband such as metal at the same time. When the small coil 34 does not receive the electromagnetic wave signal, it is determined that metal is detected. Through the control of the existing power supply control circuit, the light panel 43 is illuminated, causing the entire door panel module 11 at the corresponding height position to light up, so as to remind the case personnel that metal contraband has passed.

[0093] By dividing the light board 43 into a plurality of light-emitting boards 431, the intersection of the connection between the adjacent light-emitting boards 431 is arranged opposite to the splicing board 242 and the pressing board 271, and the plurality of pressing boards 271 of the cover plate 27, the plurality of light-emitting boards 431 of the light board 43, and the splicing board 242 and the end board 243 of the connecting board 24 are staggered and overlapped with each other, which is conducive to improving the installation stability of the cover plate 27, the light board 43 and the connecting board 24 along the Z-axis direction. At the same time, the cover plate 27, the light board 43 and the connecting board 24 are divided to reduce the connection distance. The form of the connecting unit is conducive to reducing the size of the production mold and saving production costs, while facilitating splicing along the direction of passing through the detection door (Y-axis direction). According to the width of the door mounting plate 3 along the Y-axis direction and the required size of the coil 33, the vertical plate 21 and the widening plate 22 are spliced ​​and assembled along the Y-axis direction to form a corresponding width dimension. The cover plate 27, the light board 43 and the connecting plate 24 are respectively spliced ​​using corresponding component units to form a corresponding width, which is conducive to providing flexibility in providing the door panel module 11 with corresponding width.

The plug-in board 72, the middle plate 711 and the edge plate 714 are all made of light-guiding material with uniform light. The lamp panel 43 is controlled by an existing on-off switch.

[0095] Specifically, by setting a light supply hole 734 on the top plate 73, and the plug-in plate 72, the middle plate 711 and the edge plate 714 are all made of a light-conducting material with uniform light, when the light plate 78 of the door head plate 7 is controlled by the existing on-off switch to light up, the door head plate 7 generates brightness as a whole. Since the door head plate 7 is located at the top of the detection door, it helps to remind people of the position of the detection door.
