[0042] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the utility model will be described in detail below with reference to the drawings. Obviously, the described embodiments are part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the scope of protection of the utility model.
[0043] Embodiment one
[0044] Referring to Figures 1 to 4 The present embodiment provides a sampling rod with a counting function for checking explosives, which is used for clamping test paper 500 for sampling, and the sampling rod comprises a shell 100, a paper holding mechanism 200 and a counter 300.
[0045] The shell 100 can be configured as a long cylindrical structural member, and a silica gel sleeve 130 is arranged on the outer side of the shell 100 to play a role of anti-skid and facilitate holding.
[0046] A flat paper inlet 111 is formed in one end of the shell 100, which is used for the test paper 500 to enter or exit, and a paper storage space 112 is further arranged inside the shell 100 and extends from the paper inlet 111 to the inside, which can accommodate the test paper 500. Below the paper storage space 112, opposite inner side walls of the shell 100 are provided with guide grooves 115, which extend along the length direction of the shell 100.
[0047] In some specific embodiments, in order to facilitate the paper outlet of the test paper 500, a chamfer is arranged inside the shell 100 at the position of the paper inlet 111 to form a guide part 113.
[0048] The paper holding mechanism 200 comprises a paper holding plate 210 and an elastic member 220. The paper holding plate 210 is arranged in parallel with the paper storage space 112, is slidably connected inside the shell 100, and is located below the paper storage space 112.
[0049] Both ends of the paper holding plate 210 are respectively configured as a paper holding end 211 and a trigger end 212. The paper holding end 211 is configured as a flat plate structure, is arranged in the guide groove 115, and can freely slide along the guide groove 115. The paper holding end 211 extends out of the shell 100 from one end of the shell 100 where the paper inlet 111 is formed. Since the test paper 500 is relatively soft, the part of the paper holding end 211 extending out of the shell 100 can play a role of supporting the test paper 500.
[0050] The elastic member 220 is connected with the paper holding plate 210. When the paper holding plate 210 slides into the shell 100, the elastic member 220 is stretched or compressed to occur recoverable elastic deformation.
[0051] In some specific embodiments, the trigger end 212 is configured in a cylindrical structure, the elastic member 220 is a spring, which is sleeved on the trigger end 212 and is compressed between the limiting portion on the paper supporting plate 210 and the inner wall of the shell 100. When the paper supporting end 211 is subjected to an external force to slide the paper supporting plate 210 to the inside of the shell 100, the elastic member 220 is compressed. When the external force on the paper supporting end 211 is removed, the elastic member 220 is released to reset the paper supporting plate 210.
[0052] The counter 300 is arranged in the shell 100. When the paper supporting plate 210 slides to the inside of the shell 100, the trigger end 212 can trigger the inductive switch 310 of the counter 300 to increase the count of the counter 300 by one.
[0053] In some specific embodiments, the counter 300 is an electronic counter. The battery 340 for supplying power to the counter 300 is arranged at the tail of the shell 100, i.e. the end away from the paper inlet 111, which can also play a role in balancing the weight.
[0054] The inductive switch 310 can be of various types such as mechanical, electromagnetic or laser. In the present embodiment, a magnetic reed switch is used as the inductive switch 310. Correspondingly, a magnet 213 is arranged on the trigger end 212 of the paper supporting plate 210.
[0055] In order to better realize the counting function, in the present embodiment, the counter 300 has a display screen 320 which can display the count in real time. The display screen 320 is arranged on the shell 100 for the operator to observe. Meanwhile, the counter 300 also has an alarm function. When the count of the counter 300 reaches a preset value, the counter 300 can issue an alarm to remind the operator to take corresponding actions.
[0056] The operation can be to replace the test paper 500. After the test paper 500 is replaced, the count of the counter 300 needs to be reset to zero. Therefore, in the present embodiment, the counter 300 also has a reset function. A reset button 330 for resetting is arranged on the shell 100 for the operator to operate.
[0057] The working principle of the explosive inspection sampling rod with a counting function provided in the present embodiment is as follows:
[0058] Before use, the operator inserts the test paper 500 into the paper storage space 112 through the paper inlet 111 so that part of the test paper 500 remains outside the shell 100 for collecting explosive samples.
[0059] In use, the operator holds the housing 100 to take a sample, and the test paper 500 after sampling needs to be put into the instrument for detection. In the process of inserting the test paper 500 into the instrument in alignment with the detection port of the instrument, the paper supporting end 211 of the paper supporting plate 210 located below the test paper 500 is compressed to contact the instrument, so that the entire paper supporting plate 210 slides to the inside of the housing 100. At this time, the trigger end 212 of the paper supporting plate 210 triggers the induction switch 310 of the counter 300, so that the counter 300 counts plus one.
[0060] After a period of use, when the count of the counter 300 reaches a preset value, it means that the number of uses of the test paper 500 has reached the specified requirement, and at this time the test paper 500 needs to be replaced: the operator extracts the used test paper 500 from the paper inlet 111, inserts a new test paper 500 into the paper storage space 112 through the paper inlet 111, and then the operator resets the count of the counter 300 to zero through the reset button 330 on the housing 100, and enters the next use cycle.
[0061] Embodiment Two
[0062] Referring to Figures 1 to 9 The embodiment provides a sampling rod for explosive inspection with a counting function, which is different from the first embodiment in that the housing 100 is configured in a split structure, and the housing 100 comprises a paper bin 110 and a holding rod 120 which are detachably connected.
[0063] In some specific embodiments, the paper bin 110 and the holding rod 120 are detachably connected through a buckle structure, and the buckle structure comprises a buckle 140 arranged at an end of the paper bin 110 and a buckle slot 150 arranged at an end of the holding rod 120. The buckle 140 and the buckle slot 150 can be connected in a press type or a rotary type.
[0064] The paper inlet 111 is arranged at an end of the paper bin 110 away from the holding rod 120, the paper storage space 112 is also arranged in the paper bin 110, the paper supporting plate 210 is arranged in the paper bin 110, and the counter 300 is arranged in the holding rod 120. When the paper supporting plate 210 slides to an end away from the paper inlet 111, the trigger end 212 can be extended from the paper bin 110, enter the holding rod 120 through an avoiding hole 121 arranged at an end of the holding rod 120, and trigger the induction switch 310.
[0065] The paper bin 110 and the holding rod 120, i.e. the sampling rod body part, are independently arranged, the paper bin 110 can be conveniently replaced, when the specification, property and the like of the test paper 500 are changed, the paper bin 110 can be replaced alone, the holding rod 120 becomes a universal body part, and the equipment investment can be reduced.
[0066] Embodiment three
[0067] Reference Figures 1 to 10 Since the test paper 500 is relatively soft, it is inconvenient to replace the test paper 500, therefore, in order to facilitate the replacement of the test paper 500, the embodiment provides an explosive article inspection sampling rod with a counting function, which is based on the embodiment one and increases the paper pushing mechanism 400.
[0068] The paper pushing mechanism 400 comprises a paper pushing plate 410 and a knob 420.
[0069] The paper pushing plate 410 is arranged in the shell 100 in parallel with the paper storage space 112, the paper pushing plate 410 is located above the paper supporting plate 210, and the gap between the surface of the paper pushing plate 410 and the internal structure of the shell 100 forms the paper storage space 112, that is, the test paper 500 is in contact with the surface of the paper pushing plate 410 in the paper storage space 112, the paper pushing plate 410 can freely slide in the extension direction of the paper storage space 112 in the shell 100, and the paper pushing plate 410 can drive the test paper 500 to move together through the friction between them in the movement process.
[0070] In some specific embodiments, the surface of the paper pushing plate 410 in contact with the test paper 500 is further provided with an anti-skid pad 430 to increase the friction between the paper pushing plate 410 and the test paper 500.
[0071] The knob 420 is at least partially arranged outside the shell 100 and connected with the paper pushing plate 410 through the shell 100, for this purpose, the outer wall of the shell 100 is provided with an elongated accommodating groove 114 extending along the extension direction of the paper storage space 112 and used for accommodating the knob 420, the accommodating groove 114 can limit and guide the knob 420, the bottom of the accommodating groove 114 is in communication with the inside of the shell 100, facilitating the connection between the knob 420 and the paper pushing plate 410; by rotating the knob 420, the paper pushing plate 410 can be driven to slide along the extension direction of the paper storage space 112.
[0072] The working principle of the explosive article inspection sampling rod with a counting function provided in the embodiment is as follows:
[0073] When the test paper 500 is replaced, the push button 420 is pushed to the outside of the shell 100, which drives the push plate 410 to move to the outside of the shell 100. During the movement of the push plate 410, the friction between the push plate 410 and the test paper 500 drives the test paper 500 to move to the outside of the shell 100 together, so that the test paper 500 is pushed out of the paper inlet 111, and the operator can easily pull out the test paper 500. When the operator inserts a new test paper 500 into the paper inlet 111, the push button 420 is pushed to the inside of the shell 100, which drives the push plate 410 to move to the inside of the shell 100. During the movement of the push plate 410, the friction between the push plate 410 and the test paper 500 drives the test paper 500 to move to the inside of the shell 100 together, so that the test paper 500 is inserted into the paper storage space 112.
