Technical Field
[0001] This application relates to the technical field of security equipment, and particularly relates to a chute device for a security inspection door and a security inspection device. Background Art
[0002] A security inspection door is a detection device for detecting whether a person is carrying metal items, also known as a metal detection door. Currently, security inspection doors are mainly used in public places with a large flow of people such as airports, railway stations, and large conference halls to check for suspicious metal items on the bodies of inspected personnel to ensure personnel safety.
[0003] In practical applications, when an inspected person passes through a security inspection door, metal items such as mobile phones and keys carried by the inspected person are likely to cause false alarms on the security inspection door. Utility Model Content
[0004] The purpose of the embodiments of this application is to provide a chute device for a security inspection door and a security inspection device, which can solve the problem that false alarms on the security inspection door are easily caused by metal items carried by inspected personnel when passing through the security inspection door.
[0005] To solve the above technical problems, this application is implemented as follows:
[0006] In a first aspect, the embodiments of this application provide a chute device for a security inspection door, including a device main body and a shielding member.
[0007] The device main body is provided with a chute, and the chute is provided with a chute entrance and a chute exit.
[0008] At least a part of the shielding member is arranged in the chute. The shielding member has a conveying channel. In the extending direction of the conveying channel, the shielding member is located between the chute entrance and the chute exit, and a part of the bottom of the chute is located in the conveying channel.
[0009] In a second aspect, the embodiments of this application further provide a security inspection device, including a security inspection door and the above-mentioned chute device for a security inspection door. The security inspection door is provided with a security inspection passage, and in the width direction of the security inspection passage, the chute device for a security inspection door is arranged side by side with the security inspection door.
[0010] In the embodiment of the present application, the security door chute device includes a device main body and a shielding member. The device main body is provided with a chute, the chute is provided with a chute inlet and a chute outlet, at least part of the shielding member is arranged in the chute, the shielding member has a conveying channel, and in the extending direction of the conveying channel, the shielding member is located between the chute inlet and the chute outlet, and part of the bottom of the chute is located in the conveying channel. When a person to be inspected undergoes security inspection, metal items can be put into the chute from the chute inlet. When the security inspection is completed and the person reaches the other side of the security door, the metal items slide from the chute inlet to the chute outlet. At this time, the person to be inspected can take the metal items located at the chute outlet, thereby avoiding false alarms of the security door caused by the metal items carried with the person when passing through the security door; moreover, this solution shields the metal items in the chute by arranging the shielding member, avoiding interference of the metal items in the chute to the security door.

[0024] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are some, but not all, of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.
[0025] The terms "first", "second", etc. in the description and claims of the present application are used to distinguish similar objects, rather than to describe a specific order or sequence. It should be understood that such data can be interchanged under appropriate circumstances so that the embodiments of the present application can be implemented in an order other than those illustrated or described herein. In addition, "and / or" in the description and claims means at least one of the connected objects, and the character " / " generally indicates an "or" relationship between the associated objects before and after.
[0026] Next, in conjunction with the accompanying drawings, the security inspection door chute device and security inspection equipment provided by the embodiments of the present application will be described in detail through specific embodiments and their application scenarios.
[0027] Refer to Figures 1 to 7 , an embodiment of the present application discloses a security inspection door chute device, which includes a device main body 100 and a shielding part 200. Optionally, the shielding part 200 is a magnetically conductive metal structure, which can be made of SECC (Steel Electrolytic Cold Commercial, cold-rolled steel plate), which has the characteristics of low price and easy processing. Of course, other types of magnetically conductive metal structures can also be selected, and the embodiments of the present application do not make specific limitations on this.
[0028] The device main body 100 is provided with a chute 110, the chute 110 is provided with a chute entrance 111 and a chute exit 112, and the openings of the chute entrance 111 and the chute exit 112 are both opposite to the bottom of the chute 110, so as to facilitate the inspected person to put in and take out metal items. The metal items here can specifically be items such as keys and mobile phones.
[0029] At least part of the shielding member 200 is disposed in the chute 110. The shielding member 200 has a conveying channel 210 for allowing metal items to pass through. In the extending direction of the conveying channel 210, the shielding member 200 is located between the chute entrance 111 and the chute exit 112, and part of the bottom of the chute 110 is located in the conveying channel 210. The metal item placed in the chute entrance 111 moves through the conveying channel 210 to the chute exit 112 for the inspected person to take.
[0030] In the embodiment of the present application, when the inspected person undergoes security inspection, the metal item can be put into the chute 110 from the chute entrance 111. When the security inspection is completed and the inspected person reaches the other side of the security door 710, the metal item slides from the chute entrance 111 to the chute exit 112. At this time, the inspected person can take the metal item located at the chute exit 112, thus avoiding false alarms of the security door 710 caused by the metal items carried by the inspected person when passing through the security door 710; moreover, by providing the shielding member 200, the metal items in the chute 110 are shielded, avoiding interference of the metal items in the chute 110 to the security door 710. At this time, the security door chute device 720 can be placed close to the security door 710, so as to facilitate the inspected person to place the metal items carried with them. When the inspected person completes the security inspection and passes through the security door 710, the metal item located at the chute exit 112 can be taken in time. During this process, since the distance between the security door chute device 720 and the security door 710 is relatively close, this can greatly shorten the time for the inspected person to put in and take out metal items, thereby improving the security inspection efficiency.
[0031] In an alternative embodiment, the shielding member 200 has a top plate 220 which forms the top surface of the conveying channel 210. Optionally, the top plate 220 can be a flat plate structure or a U-shaped structure, and no specific limitation is imposed here. Optionally, the top plate 220 can be arranged horizontally or inclined relative to the bottom of the chute 110. In this case, the minimum distance between the top plate 220 and the bottom of the chute 110 needs to be increased to facilitate the smooth passage of metal objects through the conveying channel 210. Alternatively, in the extending direction of the chute 110, the distance between the bottom of the chute 110 and the top plate 220 remains unchanged. This can not only prevent the metal objects placed at the chute entrance 111 from getting stuck in the conveying channel 210, so that the metal objects in the chute 110 can smoothly slide from the chute entrance 111 to the chute exit 112, but also the height of the two side walls of the shielding member 200 connected to the top plate 220 remains unchanged in the length direction of the chute 110, which is convenient for manufacturing and can save the manufacturing materials of the shielding member 200. In addition, this setting method can improve the aesthetic appearance of the security door chute device.
[0032] In a further alternative embodiment, the device main body 100 further includes a protection plate 140 which is arranged at the notch of the chute 110. The protection plate 140 is located on the side of the top plate 220 away from the bottom, and the protection plate 140 faces the top plate 220 and the two are arranged at intervals. Optionally, the protection plate 140, the top plate 220 and the bottom of the chute 110 can be parallel to each other. The protection plate 140 can be connected to the top plate 220 of the shielding member 200, or the protection plate 140 is connected between the two side walls of the chute 110 along the width direction of the chute 110, that is, in the width direction of the chute 110, the protection plate 140 is connected between the opposite two side walls of the chute 110, thereby improving the structural stability of the device main body 100. The length of the protection plate 140 is less than the length of the chute 110 to form a chute entrance 111 and a chute exit 112 in the length direction of the chute 110. Optionally, in the length direction of the chute 110, the protection plate 140 can be arranged in the middle area of the chute 110 so that the sizes of the chute entrance 111 and the chute exit 112 are basically the same, thus facilitating the placing and taking of metal objects.
[0033] Optionally, in the length direction of the chute 110, the length of the protection plate 140 can be equal to the length of the chute 110; or the length of the protection plate 140 is greater than the length of the chute 110, and both ends of the protection plate 140 protrude from the shielding member 200, thereby preventing the shielding member 200 from being exposed. This can not only protect the shielding member 200, but also improve the aesthetic appearance of the security door chute device.
[0034] Optionally, the shielding member 200 further includes a first side plate 230 and a second side plate 240 which are oppositely arranged. The top plate 220 is connected between the first side plate 230 and the second side plate 240. Protective flanges 231 are provided at the edges of the first side plate 230 and the second side plate 240 close to the chute outlet 112. The protective flanges 231 are located in the conveying channel 210. When a metal object gets stuck in the conveying channel 210, the person being inspected can reach into the conveying channel 210 to pick up the metal object. At this time, the protective flanges 231 can play a protective role to avoid scratching the hand of the person being inspected.
[0035] Optionally, the protective plate 140 can be made of a non-metallic structure to avoid interference with the security gate 710. Specifically, the protective plate 140 can be made of a wooden structure, which has a relatively large structural strength on the basis of not affecting the operation of the security gate 710.
[0036] In an alternative embodiment, the device main body 100 includes a housing 150 and a conveying assembly 160. The housing 150 has an accommodation space. The shielding member 200 and the conveying assembly 160 are arranged obliquely in the same direction in the accommodation space. The first end of the conveying assembly 160 is located at the chute inlet 111, and the second end of the conveying assembly 160 is located at the chute outlet 112. The position where the first end of the conveying assembly 160 is located is higher than the position where the second end of the conveying assembly 160 is located. The conveying assembly 160 and a part of the side wall of the accommodation space form a chute 110, and the conveying assembly 160 forms the bottom of the chute 110. This solution conveys the metal objects in the chute 110 through the conveying assembly 160, which can prevent the metal objects from not being able to slide to the chute outlet 112 due to large frictional force between the metal objects and the bottom of the chute 110, so as to ensure that the metal objects in the chute 110 can smoothly slide to the chute outlet 112, thereby improving the working efficiency of the security gate chute device for conveying metal objects; moreover, the inclined arrangement of the conveying assembly 160 can further improve the transmission efficiency of the metal objects; in addition, the shielding member 200 and the conveying assembly 160 are arranged obliquely in the same direction, which can ensure that the distance between the bottom of the chute 110 and the top plate 220 of the shielding member 200 is basically unchanged in the length direction of the chute 110, so that the metal objects in the chute 110 can smoothly pass through the conveying channel 210 and slide to the chute outlet 112. Of course, the conveying assembly 160 can also be replaced with a connecting plate, and at this time the connecting plate is arranged obliquely.
[0037] Optionally, the shielding member 200 can be disposed on the conveying assembly 160; alternatively, in other alternative embodiments, the device body 100 further includes a support plate 130 connected to the housing 150. The setting of the support plate 130 improves the structural stability of the housing 150. The support plate 130 is disposed in the accommodation space, below the conveying assembly 160. The shielding member 200 is disposed on the support plate 130. In the width direction of the conveying channel 210, the shielding member 200 has a first side plate 230 and a second side plate 240 disposed opposite to each other. The conveying assembly 160 is located between the first side plate 230 and the second side plate 240, and there are gaps between the conveying assembly 160 and the first side plate 230 and between the conveying assembly 160 and the second side plate 240. Since the conveying assembly 160 generates vibrations during the process of conveying metal articles, if the vibrations are transmitted to the shielding member 200, because the shielding member 200 is usually a magnetically conductive metal structure, the metal vibrations will affect the operation of the security gate 710, such as causing false alarms of the security gate 710. Therefore, in this solution, the shielding member 200 is spaced from the conveying assembly 160, so as to extend the transmission path of the vibrations generated by the conveying assembly 160, and further reduce the influence of the vibrations on the security gate 710.
[0038] Optionally, in the width direction of the conveying channel 210, avoiding grooves 164 are provided on both opposite side surfaces of the conveying assembly 160 for avoiding the first side plate 230 and the second side plate 240 of the shielding member 200, so that there are gaps between the portions of the conveying assembly 160 facing the shielding member 200 and the first side plate 230 and the second side plate 240 respectively, while the assembly gaps between the portions of the conveying assembly 160 at the chute inlet 111 and the chute outlet 112 and the side walls of the chute 110 are relatively small and can even be in contact, so as to prevent small-sized metal articles from falling below the conveying assembly 160.
[0039] Optionally, the shielding member 200 can be a U-shaped structure; alternatively, the shielding member 200 is an annular structure. At this time, the shielding member 200 further includes a bottom plate 250, and the bottom plate 250 is connected to the support plate 130, so as to increase the connection area between the shielding member 200 and the support plate 130, and further improve the stability of the shielding member 200.
[0040] In a further alternative embodiment, in the width direction of the conveying channel 210, the accommodation space of the housing 150 has a first side surface and a second side surface disposed opposite to each other. There are gaps between the first side plate 230 and the first side surface and between the second side plate 240 and the second side surface respectively, so as to further extend the transmission path of the vibrations generated by the conveying assembly 160 to reduce the vibration intensity received by the shielding member 200. Of course, the first side plate 230 and the first side surface and the second side plate 240 and the second side surface can also be in contact.
[0041] Optionally, the support plate 130 is connected between the first side and the second side. The accommodating space of the housing 150 has a third side and a fourth side that are oppositely arranged in the extending direction of the conveying channel 210. The conveying assembly 160 is connected between the third side and the fourth side, that is, the conveying assembly 160 and the support plate 130 are connected to different side walls of the housing 150, so as to further extend the transmission path of the vibration generated by the conveying assembly 160.
[0042] In an embodiment where the device body 100 includes the protection plate 140, the device body 100 further includes a housing 150 and a conveying assembly 160. The housing 150 has an accommodating space. The shielding member 200 and the conveying assembly 160 are arranged obliquely in the same direction in the accommodating space. The first end of the conveying assembly 160 is located at the chute entrance 111, and the second end of the conveying assembly 160 is located at the chute exit 112. The position where the first end of the conveying assembly 160 is located is higher than the position where the second end of the conveying assembly 160 is located. The conveying assembly 160 and a part of the side wall of the accommodating space form a chute 110. The conveying assembly 160 forms the bottom of the chute 110. The protection plate 140 is arranged at the notch of the chute 110. The protection plate 140 is located on the side of the top plate 220 away from the bottom of the chute 110. The protection plate 140 faces the top plate 220, and the two are arranged at intervals, which can prevent the vibration generated by the conveying assembly 160 from being transmitted to the shielding member 200 through the housing 150 and the protection plate 140 in sequence.
[0043] In another alternative embodiment, the conveying assembly 160 includes a fixing plate 161, a buffer pad 162, and a conveying member 163 that are stacked in sequence. The fixing plate 161 is connected to the housing 150. The setting of the fixing plate 161 can improve the structural stability of the housing 150. The conveying member 163 and a part of the side wall of the accommodating space form a chute 110. The conveying member 163 forms the bottom of the chute 110. Since vibrations are generated when the metal object slides relative to the conveying member 163, a buffer pad 162 is arranged below the conveying member 163 to absorb the vibrations generated by the conveying member 163, thereby reducing the vibration intensity received by the fixing plate 161, and further reducing the vibration intensity transmitted to the shielding member 200, and even avoiding the shielding member 200 from being vibrated.
[0044] In an alternative embodiment, the conveying member 163 includes a bracket 163a and a plurality of rollers 163b that are sequentially arranged at intervals along the length direction of the chute 110. The bracket 163a is provided with a receiving groove. Both ends of each roller 163b are rotatably connected to opposite side walls of the receiving groove. Each roller 163b is used to contact the object to be conveyed (i.e., the metal object). The roller 163b has the characteristics of flexible rotation and high structural strength. In this solution, the conveying member 163 with this structure is adopted, and its transmission efficiency is relatively high and it is simple to manufacture. Of course, the above-mentioned conveying member 163 can also be a ball-type structure or a conveyor belt.
[0045] Optionally, the number of the conveying members 163 may be one; alternatively, the number of the conveying members 163 is at least two, and the conveying members 163 are arranged side by side in sequence along the width direction of the chute 110 and are connected to each other. At this time, the lengths of the rollers 163b of the conveying members 163 may be set to be smaller, so as to improve the structural strength of each conveying member 163.
[0046] In yet another alternative embodiment, the security door chute device further includes a pressing block 300. In the length direction of the chute 110, the chute 110 has a first side wall and a second side wall which are oppositely arranged, and the pressing block 300 is arranged on both the first side wall and the second side wall. The pressing block 300 presses on the conveying assembly 160 to prevent the other end of the conveying assembly 160 from tilting when a metal object is placed at one end of the conveying assembly 160, thereby improving the stability of the conveying assembly 160. Of course, the pressing block 300 may not be provided.
[0047] Optionally, the security door chute device further includes a shock-absorbing gasket 400. A shock-absorbing gasket 400 is arranged between the pressing block 300 and the conveying assembly 160. Since the conveying assembly 160 generates vibrations during the process of conveying metal objects, the shock-absorbing gasket 400 is provided to absorb part of the vibrations generated by the conveying assembly 160, thereby reducing the vibrations received by the shielding member 200. Of course, the shock-absorbing gasket 400 may not be provided.
[0048] Optionally, the above-mentioned protective plate 140, fixing plate 161, support plate 130 and pressing block 300 are all non-metallic structures, specifically, they may be wooden structures, which have the characteristic of relatively large structural strength. Of course, they may also be other types of non-metallic structures, and the embodiments of the present application do not make specific limitations thereto.
[0049] In an alternative embodiment, the outer shell 150 is made of a non-metallic structure to avoid affecting the security door 710. Optionally, the outer shell 150 is made of a wooden structure with relatively high structural strength. Of course, the outer shell 150 can also be made of a plastic structure, etc., and no specific limitation is made here. The outer shell 150 includes a first side baffle 151, a second side baffle 152, a third side baffle 153, and a fourth side baffle 154 that are sequentially connected end to end. The first side baffle 151 is opposite to the third side baffle 153, and the second side baffle 152 is opposite to the fourth side baffle 154 to enclose the accommodation space described above. The height of the first side baffle 151 is greater than the height of the third side baffle 153. In the extending direction of the first side baffle 151 towards the third side baffle 153, the bottom of the chute 110 is inclined downward, and the heights of both the second side baffle 152 and the fourth side baffle 154 gradually decrease, so that the groove depth at each part of the chute 110 is equal, thereby preventing the metal objects in the chute 110 from falling out of the chute 110. Of course, the height of the first side baffle 151 can also be equal to or less than the height of the third side baffle 153. In the extending direction of the first side baffle 151 towards the third side baffle 153, only the bottom of the chute 110 is inclined downward. At this time, the groove depth of the chute outlet 112 is greater than the groove depth of the chute inlet 111, which is not convenient for the inspected person to take the metal object; or the groove depth of the chute outlet 112 is less than the groove depth of the chute inlet 111, and at this time, the metal object sliding to the chute outlet 112 is likely to fall.
[0050] In a further alternative embodiment, the outer shell 150 further includes at least two connecting plates 155. Each connecting plate 155 is connected between the second side baffle 152 and the fourth side baffle 154, and the connecting plates 155 are arranged at intervals in sequence along the extending direction of the first side baffle 151 towards the third side baffle 153. Each connecting plate 155 is used to connect the second side baffle 152 and the fourth side baffle 154, thereby enhancing the connection firmness and stability between the side baffles of the outer shell 150.
[0051] Optionally, the security door chute device further includes a handle 500. Installation grooves 151a are provided on both the first side baffle 151 and the third side baffle 153. The handle 500 is arranged in the installation groove 151a, and the handle 500 is arranged in one-to-one correspondence with the installation groove 151a. During the process of carrying the security door chute device, the staff holds the handle 500 for easy carrying. Optionally, the handle 500 is arranged close to the chute 110.
[0052] Optionally, the wooden structures in the above embodiments can be connected by an eccentric wheel assembly, and both the connection firmness and environmental friendliness are relatively good. Of course, screw connection can also be used, and no specific limitation is made in the embodiments of the present application.
[0053] In another alternative embodiment, the security door chute device further includes a tail buffer plate 600. The tail buffer plate 600 is disposed at the chute outlet 112. The tail buffer plate 600 is connected to the first side wall of the chute 110. The tail buffer plate 600 faces the outlet of the conveying channel 210. Optionally, the tail buffer plate 600 can be a deformable member. When the metal article slides in the chute 110 from the chute inlet 111 to the chute outlet 112, there is a certain inertia. By providing the tail buffer plate 600 to contact the metal article at the chute outlet 112, part of the inertia of the metal article can be absorbed, so as to prevent the metal article from directly contacting the side wall of the chute 110, thereby protecting the metal article. Of course, the tail buffer plate 600 can also be not provided, and the inclination of the chute 110 can be reduced to reduce the inertia of the metal article.
[0054] Based on the security door chute device provided by the embodiments of the present application, the embodiments of the present application further provide a security inspection device, which includes a security door 710 and the security door chute device 720 described in any of the above embodiments. The security door 710 is provided with a security inspection channel 711. In the width direction of the security inspection channel 711, the security door chute device 720 is arranged side by side with the security door 710.
[0055] In an alternative implementation manner, the security inspection device further includes at least one of the following:
[0056] The shielding member 200 is aligned with the detection coil in the security door 710, and the detection coil is used to detect the person to be inspected located in the security inspection channel 711;
[0057] In the extending direction (i.e., the passing direction) of the security inspection channel 711, the length of the shielding member 200 is greater than the length of the detection coil in the security door 710;
[0058] In the extending direction of the security inspection channel 711, both ends of the shielding member 200 protrude from the detection coil in the security door 710.
[0059] By utilizing the magnetic field shielding principle of the shielding member 200, the metal articles in the chute 110 of the security door chute device 720 are prevented from interfering with the detection coil in the security door 710.
[0060] In the extending direction of the security inspection passage 711 (i.e., the passing direction of the security inspection passage 711), the length of the shielding member 200 is greater than the length of the detection coil, so as to increase the shielding area of the shielding member 200 and improve the shielding effect of the shielding member 200. Optionally, when the length of the shielding member 200 is greater than the length of the detection coil, only one end of the shielding member 200 can protrude from the detection coil, and the other end can be flush with the detection coil; alternatively, both ends of the shielding member 200 protrude from the detection coil, so that the shielding range formed by the shielding member 200 is more uniformly distributed relative to the distribution of the detection coil, thereby further improving the shielding effect of the shielding member 200.
[0061] Further optionally, in the extending direction of the security inspection passage 711, the dimensions by which both ends of the shielding member 200 protrude from the detection coil can be 30-40 cm, so as to improve the shielding effect of the shielding member 200. In this case, both ends of the shielding member 200 can protrude from the security door 710. Of course, the above dimensions can also be selected according to actual needs, and the embodiments of the present application do not make specific limitations thereto.
[0062] The embodiments of the present application have been described above in conjunction with the accompanying drawings. However, the present application is not limited to the above specific embodiments. The above specific embodiments are merely illustrative and not restrictive. Under the inspiration of the present application, those of ordinary skill in the art can also make many forms without departing from the purpose of the present application and the scope protected by the claims, and all of them belong to the protection scope of the present application.
