Description

Technical Field

[0001] This utility model relates to the field of explosives inspection technology, and more specifically, to an explosives inspection sampling rod with a paper storage compartment. Background Technology

[0002] Airport explosive detection is a crucial part of ensuring airport security. Its purpose is to use a series of technical means to detect whether passengers and their luggage are carrying explosives or other dangerous items, thereby ensuring the safety of the airport and its passengers. Among these measures, trace detection of explosive materials is an important screening step in airport security checks.

[0003] Trace detection uses a sampling strip made of Teflon to absorb trace amounts of substances from the surface of an object. The sample is then placed into a testing instrument for analysis. Once the sample strip containing trace substances is placed into a specific testing instrument, the instrument can detect any contraband such as explosives or drugs that a passenger has ever come into contact with, even if the amount is extremely small.

[0004] During the sampling process, the test strip is usually inserted into the sampling rod, and the sampling rod holds the test strip for sampling. Because the test strip is relatively soft, the process of inserting it into the sampling rod is difficult, which affects work efficiency.

[0005] Due to the characteristics of test strips, they need to be replaced after a certain number of uses. Therefore, operators need to accurately record the number of times the test strips have been used. Currently, the recording methods are all done manually by memorizing or taking notes. However, these methods suffer from poor accuracy and low efficiency. Utility Model Content

[0006] The purpose of this invention is to provide an explosives inspection sampling rod with a paper storage compartment to solve the technical problems existing in the background art.

[0007] To solve the above-mentioned technical problems, this utility model adopts the following technical solution:

[0008] An explosives inspection sampling rod with a paper storage compartment, comprising:

[0009] A paper storage bin 100 includes a bin body 110, a pressing plate 120, and a pushing plate 130. The pressing plate 120 and the pushing plate 130 are arranged parallel to each other within the bin body 110, and the gap between the pressing plate 120 and the pushing plate 130 forms a paper storage space 150. One end of the bin body 110 has a paper outlet 111, and the other end has a paper inlet 112 and a vertically extending limiting groove 113. The paper outlet 111 and the paper inlet 112 are connected to the paper storage space 150. The pressing plate 120... The pressure plate 120 is connected to the inner wall of the paper tray body 110 via a first elastic element 140. When the position of the pressure plate 120 changes in the vertical direction, the first elastic element 140 is stretched or compressed and undergoes a recoverable elastic deformation. One end of the pressure plate 120 is provided with a lever 121, which extends out of the paper tray body 110 from the limiting groove 113. The push plate 130 is horizontally slidably connected inside the paper tray body 110. The push plate 130 is provided with a knob 131, which is at least partially located on the outside of the paper tray body 110.

[0010] The paper-holding mechanism 200 includes a paper-holding plate 210 and a second elastic element 220. The paper-holding plate 210 is arranged parallel to the paper storage space 150 and is slidably connected to the paper tray body 110. Both ends of the paper-holding plate 210 extend from both ends of the paper tray body 110. The second elastic element 220 is connected to the paper-holding plate 210. When the paper-holding plate 210 slides toward one end of the paper inlet 112, the second elastic element 220 is stretched or compressed and undergoes recoverable elastic deformation.

[0011] The sampling rod body 300 is detachably connected to the paper tray body 110 at one end where the paper inlet 112 is located.

[0012] Furthermore, a chamfer is provided inside the paper tray body 110 at the position of the paper outlet 111 to form a guide portion 116.

[0013] Furthermore, an anti-slip pad 132 is provided on the top surface of the pusher plate 130.

[0014] Furthermore, the paper tray body 110 and the sampling rod body 300 are detachably connected by a snap-fit ​​structure.

[0015] Furthermore, a silicone sleeve 310 is provided on the outer side of the sampling rod body 300.

[0016] Furthermore, the explosive material inspection sampling rod with a paper storage compartment also includes a counter 400, which is disposed inside the sampling rod body 300. When the paper tray 210 slides toward the paper inlet 112, the paper tray 210 can trigger the induction switch 410 of the counter 400, causing the counter 400 to increment by one.

[0017] Furthermore, a reed switch is used as the sensing switch 410, and correspondingly, a magnet 213 is provided on one end of the tray 210 near the sensing switch 410.

[0018] Furthermore, the counter 400 has a display screen 420 that can display the count in real time, and the display screen 420 is disposed on the sampling rod body 300.

[0019] Furthermore, the counter 400 has a count reset function, and a reset button 430 for count reset is provided on the sampling rod body 300.

[0020] Furthermore, the counter 400 has an alarm function. When the counter 400 counts to a preset value, the counter 400 can issue an alarm.

[0021] Compared with the prior art, the beneficial effects of this utility model are:

[0022] One of the above technical solutions provides an explosive material inspection sampling rod with a paper storage compartment. By setting up the paper storage compartment, a certain number of test strips can be pre-placed into the paper storage compartment through the paper inlet. When in use, the test strips stored in the paper storage compartment are pushed out one by one through the paper outlet by the contact between the pusher plate and the test strips under the action of friction between the two. This can effectively solve the problem of difficulty in replacing test strips in existing sampling rods and improve sampling efficiency.

[0023] Another technical solution mentioned above provides an explosive material inspection sampling rod with a paper storage compartment. The sampling rod is designed as a split structure, so that the paper storage compartment and the main body of the sampling rod are set independently. This allows for easy replacement of the paper storage compartment. When the specifications or properties of the test paper change, the paper storage compartment can be replaced separately, making the main body of the sampling rod a universal main body, which can reduce equipment investment.

[0024] Another technical solution mentioned above provides an explosive material inspection sampling rod with a paper storage compartment. By setting up a tray and a counter, the tray is compressed while the test paper is placed into the instrument for testing, thereby triggering the counter to count, which can realize the automatic counting of the number of times the test paper is used.

[0025] Another technical solution mentioned above provides an explosive material inspection sampling rod with a paper storage compartment. The counter has functions such as display counting and threshold alarm, which can better realize the automatic counting function and remind the operator to take relevant actions in a timely manner.

[0041] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the utility model will be described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0042] Example 1

[0043] See Figures 1 to 6 , Figure 9 This embodiment provides an explosive material inspection sampling rod with a paper storage compartment for holding test paper 500 for sampling. The sampling rod includes: a paper storage compartment 100, a paper holding mechanism 200 and a sampling rod body 300.

[0044] The paper storage compartment 100 includes a paper compartment body 110, a pressing plate 120, and a pushing plate 130. The pressing plate 120 and the pushing plate 130 are arranged parallel to each other within the paper compartment body 110, and the gap between the pressing plate 120 and the pushing plate 130 forms a paper storage space 150.

[0045] The paper storage body 110 can be constructed as a long cylindrical structure. The two ends of the paper storage body 110 are respectively provided with a paper outlet 111 and a paper inlet 112, and the paper outlet 111 and the paper inlet 112 are connected to the paper storage space 150.

[0046] The paper outlet 111 is a flat opening that can meet the requirement of a single test strip 500 extending out. The paper compartment body 110 has a chamfered guide part 116 at the position of the paper outlet 111, which can facilitate the test strip 500 to extend out of the paper outlet 111.

[0047] The paper inlet 112 needs to accommodate a certain number of stacked test papers (500 in total) in batches. The specific opening size is designed according to actual usage requirements.

[0048] The paper tray body 110 also has a limiting groove 113 extending vertically at one end where the paper inlet 112 is located, and the limiting groove 113 is located above the paper inlet 112.

[0049] The pressing plate 120 is connected to the inner wall of the paper compartment body 110 through the first elastic element 140. One end of the pressing plate 120 is provided with a lever 121. The lever 121 extends out of the paper compartment body 110 through the limiting groove 113. When an external force is applied to the lever 121, causing the pressing plate 120 to change position in the vertical direction, the first elastic element 140 is stretched or compressed to undergo recoverable elastic deformation and provides the opposite squeezing force.

[0050] In some specific embodiments, two springs are used as the first elastic element 140. The two springs are spaced apart along the length of the pressing plate 120 and are detachably connected to the inner wall of the paper bin body 110 and the pressing plate 120, respectively. The use of two springs ensures the stability of the pressing plate 120 in the vertical direction. The detachable connection between the springs and the inner wall of the paper bin body 110 and the pressing plate 120 allows for easy replacement of springs of different specifications, sizes, and elasticities as needed to change the gap between the pressing plate 120 and the push plate 130, thereby changing the size of the paper storage space 150.

[0051] The pusher plate 130 is horizontally slidably connected within the paper tray body 110. A knob 131 is provided on the pusher plate 130, and the knob 131 is at least partially located on the outside of the paper tray body 110. By moving the knob 131, the pusher plate 130 can be driven to move horizontally within the paper tray body 110. During the movement, the pusher plate 130 can drive the test paper 500 to move together through the friction between its top surface and the test paper 500. In order to increase the friction between the pusher plate 130 and the test paper 500, an anti-slip pad 132 is provided on the top surface of the pusher plate 130.

[0052] In some specific embodiments, for the installation of the pusher plate 130, an elongated receiving groove 114 extending along the length direction of the paper storage space 150 is provided on the outer wall of the paper tank body 110 for accommodating the dial 131. The receiving groove 114 can limit and guide the dial 131. The bottom of the receiving groove 114 is connected to the interior of the paper tank body 110 to facilitate the connection between the dial 131 and the pusher plate 130.

[0053] The paper-supporting mechanism 200 includes a paper support plate 210 and a second elastic element 220.

[0054] The paper support plate 210 is arranged parallel to the paper storage space 150, the pressure plate 120, and the pusher plate 130, and is located below the pusher plate 130. The paper support plate 210 is slidably connected to the paper storage body 110 in the horizontal direction. The two ends of the paper support plate 210 are configured as a paper support end 211 and a trigger end 212. The paper support end 211 is constructed as a flat plate and extends out of the paper storage body 110 from the end of the paper storage body 110 where the paper outlet 111 is opened. Since the test paper 500 is relatively soft, the part of the paper support end 211 extending out of the paper storage body 110 can support the test paper 500. The trigger end 212 is constructed as a cylindrical structure and extends out of the paper storage body 110 from the end of the paper storage body 110 where the paper inlet 112 is opened.

[0055] In some specific embodiments, for the installation of the paper tray 210, a pair of guide grooves 115 are provided opposite to each other on the inner wall of the paper tray body 110. The guide grooves 115 extend along the length direction of the paper tray body 110. The paper tray end 211 is slidably disposed in the guide grooves 115 and can slide freely along the extension direction of the guide grooves 115.

[0056] The second elastic element 220 is connected to the paper tray 210. When the paper tray 210 slides toward one end of the paper inlet 112, the second elastic element 220 is stretched or compressed and undergoes a recoverable elastic deformation.

[0057] In some specific embodiments, a spring is used as the second elastic element 220 and is sleeved on the trigger end 212. When the paper-supporting end 211 is subjected to an external force that causes the paper-supporting plate 210 to move toward the paper inlet 112, the spring, as the second elastic element 220, is compressed. When the external force on the paper-supporting end 211 is eliminated, the spring, as the second elastic element 220, is released, causing the paper-supporting plate 210 to return to its original position.

[0058] The sampling rod body 300 is detachably connected to the paper tray body 110 at one end where the paper inlet 112 is located. A first clearance hole 330 is provided on the end face of the sampling rod body 310 to avoid the lever 121 when connected to the paper storage tray 100.

[0059] The sampling rod body 300 serves as the main body for the operator to hold, and a silicone sleeve 310 is provided on its outer side to prevent slipping and improve comfort.

[0060] In some specific embodiments, the paper tray body 110 and the sampling rod body 300 can be detachably connected by a snap-fit ​​structure. The snap-fit ​​structure includes a snap-fit ​​160 disposed on the end of the paper tray body 110 and a slot 320 disposed on the end of the sampling rod body 300. The connection between the snap-fit ​​160 and the slot 320 can be a press-fit or a rotation-fit.

[0061] In another embodiment, the paper tray body 110 and the sampling rod body 300 can also be connected by means of threads or the like.

[0062] The working principle of an explosives inspection sampling rod with a paper storage compartment provided in this embodiment is as follows:

[0063] Before use, quickly separate the paper storage compartment 100 and the sampling rod body 300, and push the lever 121 upward to move the pressing plate 120 upward, expanding the height of the paper storage space 500. Then, put a certain number of test papers 500 into the paper storage space 150 in batches through the paper inlet 112. Then, release the lever 121. Under the rebound force of the first elastic member 140, the pressing plate 120 presses the batch of test papers 500 tightly.

[0064] In use, the knob 131 is turned toward the paper outlet 111 to move the pusher plate 130 toward the paper outlet 111. Through the friction between the pusher plate 130 and the test paper 500, a single test paper 500 is driven to extend from the paper outlet 111 out of the paper tray body 110. Then, the sampling rod body 300 is held by hand to perform sampling.

[0065] When it is necessary to replace the test strip 500, the operator pulls out the old test strip 500 and repeats the above-mentioned pushing action to extend a new test strip 500 out of the paper outlet 111 for sampling.

[0066] When all the test strips 500 in the paper storage compartment 100 are used up, the paper storage compartment 100 and the sampling rod body 300 can be quickly separated again to repeat the above-mentioned batch paper loading action.

[0067] Example 2

[0068] See Figures 1 to 9 This embodiment provides an explosive material inspection sampling rod with a paper storage compartment. Based on Embodiment 1, a counter 400 is added to achieve the counting function.

[0069] The counter 400 is disposed inside the sampling rod body 300. When the paper tray 210 slides toward the paper inlet 112, the trigger end 212 of the paper tray 210 extends out from the paper tray body 110 and enters the sampling rod body 300 through the second clearance hole 340 opened on the end face of the sampling rod body 300, triggering the induction switch 410 of the counter 400, so that the counter 400 counts by one.

[0070] In some specific embodiments, the counter 400 is an electronic counter, and the battery 440 that powers the counter 400 is located at the tail of the sampling rod body 300, that is, at the end away from the paper storage compartment 100, and can also play a role in balancing the weight.

[0071] The inductive switch 410 can be mechanical, electromagnetic or laser type, etc. In this embodiment, a reed switch is used as the inductive switch 410. Correspondingly, a magnet 213 is provided on the trigger end 212 of the tray 210.

[0072] To better realize the counting function, in this embodiment, the counter 400 has a display screen 420 that can display the count in real time. The display screen 420 is set on the sampling rod body 300 for easy observation by the operator. At the same time, the counter 400 has an alarm function. When the counter 400 counts to a preset value, the counter 400 can issue an alarm to remind the operator to perform corresponding operations.

[0073] The operation can be replacing the test strip 500. After replacing the test strip 500, the counter 400 needs to be reset to zero. Therefore, in this embodiment, the counter 400 also has a count reset function. The reset button 430 for count reset is set on the sampling rod body 300 for easy operation by the operator.

[0074] The working principle of an explosives inspection sampling rod with a paper storage compartment provided in this embodiment is as follows:

[0075] The operator holds the sampling rod body 300 to clamp the test strip 500 for sampling. After sampling, the test strip 500 needs to be placed into the instrument for testing. During the process of inserting the test strip 500 into the instrument by aligning it with the instrument's detection port, the paper-holding end 211 of the paper tray 210 located below the test strip 500 contacts the instrument and is compressed, thereby causing the entire paper tray 210 to slide towards the sampling rod body 300. At this time, the trigger end 212 of the paper tray 210 triggers the inductive switch 410 of the counter 400, causing the counter 400 to increment by one.

[0076] After a period of use, when the counter 400 reaches the preset value, it means that the number of times the test strip 500 has been used has reached the specified requirement. At this time, the counter 400 will issue an alarm to remind the operator to replace the test strip 500. The operation of replacing the test strip 500 is described in Example 1 and will not be repeated here. After the test strip 500 is replaced, the operator resets the counter 400 to zero using the zeroing button 430 on the sampling rod body 300 and enters the next usage cycle.
