Description

Technical Field

[0001] The invention relates to the technical field of explosive inspection, and more particularly to an explosive inspection sampling rod with a paper storage bin. Background Art

[0002] Airport explosion-proof detection is one of the important links in ensuring airport safety. Its purpose is to use a series of technical means to detect whether passengers and luggage are carrying explosives or other dangerous items, so as to ensure the safety of airports and passengers. Among them, trace detection of explosive items is an important screening link in airport security checks.

[0003] Trace detection is done by using a test sampling strip made of Teflon to absorb trace substances on the surface of an object for sampling, and then placing the test paper into a testing instrument for testing. When the test paper stained with trace substances is placed into a specific testing instrument, as long as the passenger has come into contact with explosives, drugs or other prohibited items, even if the content is extremely small, the instrument can detect them.

[0004] During the sampling process, the test paper is usually inserted into the sampling stick, and the test paper is clamped by the sampling stick for sampling. Since the test paper is soft in texture, the process of inserting it into the sampling stick is more difficult, which affects work efficiency.

[0005] Due to the characteristics of the test paper, the test paper needs to be replaced after a certain number of cycles. Therefore, the operator is required to accurately record the number of times the test paper is used. The current recording method is to use artificial brain recording or notes, which has the problems of poor accuracy and low efficiency. Summary of the invention

[0006] The object of the present invention is to provide an explosive inspection sampling rod with a paper storage bin to solve the technical problems existing in the above-mentioned background technology.

[0007] In order to solve the above technical problems, the present invention is implemented by adopting the following technical solutions:

[0008] An explosive material inspection sampling rod with a paper storage bin, comprising:

[0009] The paper storage bin 100 comprises a paper storage bin body 110, a paper pressing board 120 and a paper pushing board 130, wherein the paper pressing board 120 and the paper pushing board 130 are arranged in parallel with each other in the paper storage bin body 110, and the gap between the paper pressing board 120 and the paper pushing board 130 forms a paper storage space 150; a paper outlet 111 is provided at one end of the paper storage bin body 110, and a paper inlet 112 and a limiting groove 113 extending in a vertical direction are provided at the other end, and the paper outlet 111 and the paper inlet 112 are connected to the paper storage space 150; ... 0 is connected to the inner wall of the paper bin body 110 through a first elastic member 140. When the position of the paper pressing paper 120 changes in the vertical direction, the first elastic member 140 is stretched or compressed to generate a recoverable elastic deformation. A lever 121 is provided at one end of the paper pressing paper 120, and the lever 121 extends out of the paper bin body 110 from the limiting groove 113. The pushing paper 130 is horizontally slidably connected in the paper bin body 110, and a button 131 is provided on the pushing paper 130, and the button 131 is at least partially provided on the outside of the paper bin body 110.

[0010] The paper supporting mechanism 200 includes a paper supporting plate 210 and a second elastic member 220. The paper supporting plate 210 is arranged parallel to the paper storage space 150 and is slidably connected to the paper bin body 110. Two ends of the paper supporting plate 210 extend from two ends of the paper bin body 110 respectively. The second elastic member 220 is connected to the paper supporting plate 210. When the paper supporting plate 210 slides toward one end of the paper inlet 112, the second elastic member 220 is stretched or compressed to generate a recoverable elastic deformation.

[0011] The sampling rod body 300 is detachably connected to one end of the paper bin body 110 where the paper inlet 112 is opened.

[0012] Furthermore, a chamfered guide portion 116 is provided inside the paper bin body 110 at the position of the paper outlet 111 .

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

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

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

[0016] Furthermore, the explosive inspection sampling rod with a paper storage bin also includes a counter 400, which is arranged in the sampling rod body 300. When the paper support paper 210 slides toward one end of the paper feed port 112, the paper support paper 210 can trigger the induction switch 410 of the counter 400, so that the count of the counter 400 is increased by one.

[0017] Furthermore, a reed switch is used as the induction switch 410 , and correspondingly, a magnet 213 is provided on one end of the paper support 210 close to the induction 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 arranged on the sampling rod body 300 .

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

[0020] Furthermore, the counter 400 has an alarm function. When the count of the counter 400 reaches a preset value, the counter 400 may issue an alarm.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] One of the above technical solutions provides an explosive material inspection sampling stick with a paper storage bin. Through the setting of the paper storage bin, a certain number of test papers can be placed in batches in the paper storage bin from the paper inlet in advance. When in use, the test papers stored in the paper storage bin are pushed out from the paper outlet one by one for use through the contact between the pushing paper board and the test papers under the action of the friction between the two. This can effectively solve the problem of difficulty in replacing test papers in existing sampling sticks and improve sampling efficiency.

[0023] Another technical solution among the above technical solutions provides an explosive material inspection sampling rod with a paper storage bin, in which the sampling rod is arranged as a split structure, so that the paper storage bin and the main body of the sampling rod are arranged independently of each other, and the paper storage bin can be easily replaced. When the specifications, properties, etc. of the test paper change, the paper storage bin can be replaced separately, so that the sampling rod body becomes a universal main body, which can reduce equipment investment.

[0024] Another technical solution in the above technical solution provides an explosive material inspection sampling stick with a paper storage bin. Through the setting of a paper support and a counter, when the test paper is placed in the instrument for detection, the paper support is compressed and moved, thereby triggering the counter to count, thereby realizing automatic counting of the number of times the test paper is used.

[0025] Another technical solution in the above technical solution provides an explosive inspection sampling rod with a paper storage bin. 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 operations in time.

[0041] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the present invention is described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0042] Embodiment 1

[0043] See also Figures 1 to 6 , Fig. 9 This embodiment provides an explosive inspection sampling rod with a paper storage bin, which is used to clamp a test paper 500 for sampling. The sampling rod includes: a paper storage bin 100, a paper supporting mechanism 200 and a sampling rod body 300.

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

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

[0046] The paper outlet 111 is constructed as a flat opening, which can meet the requirement of extending a single test paper 500. A chamfered guide portion 116 is provided inside the paper bin body 110 at the position of the paper outlet 111 to facilitate the test paper 500 to extend from the paper outlet 111.

[0047] The paper inlet 112 needs to meet the requirement of batch-loading a certain number of stacked test papers 500, and the specific opening size is designed according to actual use requirements.

[0048] One end of the paper bin body 110 where the paper inlet 112 is formed is further provided with a limiting groove 113 extending in a vertical direction, and the limiting groove 113 is located above the paper inlet 112 .

[0049] The paper pressing paper 120 is connected to the inner wall of the paper bin body 110 through the first elastic member 140. A lever 121 is provided at one end of the paper pressing paper 120. The lever 121 extends out of the paper bin body 110 from the limiting groove 113. When an external force is applied to the lever 121 to change the position of the paper pressing paper 120 in the vertical direction, the first elastic member 140 is stretched or compressed to produce a recoverable elastic deformation and provide an opposite extrusion force.

[0050] In some specific embodiments, two springs are used as the first elastic member 140, and the two springs are arranged at intervals along the length direction of the paper pressing paper 120, and are detachably connected to the inner wall of the paper bin body 110 and the paper pressing paper 120 respectively; the two spring connections can ensure the stability of the paper pressing paper 120 moving in the vertical direction; the springs are detachably connected to the inner wall of the paper bin body 110 and the paper pressing paper 120, and springs of different specifications, sizes and elastic forces can be easily replaced according to needs to change the gap size between the paper pressing paper 120 and the paper pushing paper 130, thereby changing the size of the paper storage space 150.

[0051] The push paper board 130 is connected in a horizontally slidable manner in the paper bin body 110. A dial button 131 is provided on the push paper board 130. The dial button 131 is at least partially provided on the outside of the paper bin body 110. By turning the dial button 131, the push paper board 130 can be driven to move in a horizontal direction in the paper bin body 110. During the movement, the push paper board 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 push paper board 130 and the test paper 500, an anti-slip pad 132 is provided on the top surface of the push paper board 130.

[0052] In some specific embodiments, in order to install the paper pusher 130, a long strip-shaped receiving groove 114 extending along the length direction of the paper storage space 150 and used to accommodate the button 131 is opened on the outer wall of the paper bin main body 110. The receiving groove 114 can limit and guide the button 131. The bottom of the receiving groove 114 is connected to the interior of the paper bin main body 110, which facilitates the connection between the button 131 and the paper pusher 130.

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

[0054] The paper support plate 210 is arranged parallel to the paper storage space 150, the paper pressing plate 120, and the paper pushing plate 130, and is located below the paper pushing plate 130. The paper support plate 210 can be slidably connected in the paper bin main body 110 in the horizontal direction, and 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 structure, and extends out of the paper bin main body 110 at one end of the paper bin main body 110 where the paper outlet 111 is opened. Since the test paper 500 is soft in texture, the part of the paper support end 211 extending out of the paper bin main body 110 can play a role in supporting the test paper 500; the trigger end 212 is constructed as a cylindrical structure, and can extend out of the paper bin main body 110 at one end of the paper bin main body 110 where the paper inlet 112 is opened.

[0055] In some specific embodiments, in order to install the paper support paper 210, a pair of guide grooves 115 are relatively arranged on the inner wall of the paper bin body 110, and the guide grooves 115 extend along the length direction of the paper bin body 110. The paper support end 211 can be slidably arranged in the guide grooves 115 and can slide freely along the extension direction of the guide grooves 115.

[0056] The second elastic member 220 is connected to the paper support plate 210 . When the paper support plate 210 slides toward one end of the paper inlet 112 , the second elastic member 220 is stretched or compressed to generate a recoverable elastic deformation.

[0057] In some specific embodiments, a spring is used as the second elastic member 220 and is mounted on the trigger end 212. When the paper support end 211 is subjected to an external force causing the paper support board 210 to move toward the paper inlet 112, the spring serving as the second elastic member 220 is compressed. When the external force on the paper support end 211 is eliminated, the spring serving as the second elastic member 220 is released to reset the paper support board 210.

[0058] The sampling rod body 300 is detachably connected to one end of the paper bin body 110 where the paper inlet 112 is opened. A first avoidance hole 330 is opened on the end surface of the sampling rod body 310 for avoiding the lever 121 when connected to the paper bin 100.

[0059] The sampling rod body 300 is held by the operator, and a silicone sleeve 310 is provided on the outer side thereof to prevent slipping and improve comfort.

[0060] In some specific embodiments, the paper bin body 110 and the sampling rod body 300 can be detachably connected via a snap-fit ​​structure, wherein the snap-fit ​​structure includes a snap 160 disposed on the end of the paper bin body 110, and a slot 320 disposed on the end of the sampling rod body 300, and the connection between the snap 160 and the slot 320 can be a push-type snap connection or a rotational snap connection.

[0061] In another embodiment, the paper bin body 110 and the sampling rod body 300 may also be connected by threads or the like.

[0062] The working principle of the explosive inspection sampling rod with a paper storage bin provided in this embodiment is as follows:

[0063] Before use, the paper storage bin 100 and the sampling stick body 300 are quickly separated, and the lever 121 is pushed upward to move the paper pressing paper 120 upward to expand the height of the paper storage space 500. After a certain number of test papers 500 are put into the paper storage space 150 in batches through the paper inlet 112, the lever 121 is released, and the paper pressing paper 120 presses the test papers 500 put in in batches under the rebound force of the first elastic member 140.

[0064] When in use, the button 131 is pushed toward the direction of the paper outlet 111 to make the paper pushing paper 130 move toward the paper outlet 111, and the friction between the paper pushing paper 130 and the test paper 500 drives the single test paper 500 to extend out of the paper bin body 110 from the paper outlet 111, and then the sampling stick body 300 is held by hand for sampling.

[0065] When the test paper 500 needs to be replaced, the operator pulls out the old test paper 500, repeats the above-mentioned paper pushing action again, and extends a new test paper 500 out of the paper outlet 111 for sampling.

[0066] When all the test papers 500 in the paper storage bin 100 are used up, the paper storage bin 100 and the sampling stick body 300 can be quickly separated again, and the above-mentioned paper loading action can be repeated.

[0067] Embodiment 2

[0068] See also Figures 1 to 9 The explosive material inspection sampling rod with a paper storage bin provided in this embodiment is provided with a counter 400 added on the basis of the first embodiment to realize the counting function.

[0069] The counter 400 is arranged in the sampling rod body 300. When the paper support plate 210 slides toward one end of the paper feed port 112, the trigger end 212 of the paper support plate 210 extends out from the paper bin body 110 and enters the sampling rod body 300 through the second avoidance hole 340 opened on the end surface of the sampling rod body 300, triggering the induction switch 410 of the counter 400, so that the count of the counter 400 is increased by one.

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

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

[0072] In order 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 arranged on the sampling rod body 300 to facilitate the operator to observe; at the same time, the counter 400 has an alarm function. When the count of the counter 400 reaches a preset value, the counter 400 can issue an alarm to remind the operator to perform corresponding operations.

[0073] The operation may be replacing the test paper 500. After replacing the test paper 500, the count of the counter 400 needs to be reset. Therefore, in this embodiment, the counter 400 also has a count reset function. The reset button 430 for resetting the count is arranged on the sampling stick body 300 for the convenience of the operator.

[0074] The working principle of the explosive inspection sampling rod with a paper storage bin provided in this embodiment is as follows:

[0075] The operator holds the sampling stick body 300 to clamp the test paper 500 for sampling. After sampling, the test paper 500 needs to be placed in an instrument for detection. In the process of aligning the test paper 500 with the detection port of the instrument and inserting it into the instrument, the paper support end 211 of the paper support paper 210 located below the test paper 500 contacts the instrument and is compressed, so that the entire paper support paper 210 slides toward the sampling stick body 300. At this time, the trigger end 212 of the paper support paper 210 triggers the sensing switch 410 of the counter 400, causing the counter 400 to count by one.

[0076] After a period of use, when the count of the counter 400 reaches a preset value, it means that the number of times the test paper 500 has been used has reached the specified requirement. At this time, the counter 400 issues an alarm to prompt the operator to replace the test paper 500. For the operation of replacing the test paper 500, please refer to Example 1 and will not be described in detail here. After the test paper 500 is replaced, the operator clears the count of the counter 400 through the reset button 430 on the sampling stick body 300 and enters the next use cycle.
