[0002] Bees are rapidly proliferating, and incidents of human casualties caused by bee stings occur from time to time. Anti-bee clothing is a special protective clothing for preventing insect invasion, and is widely used in China.

[0003] However, there are many types of wasps, and in biological classification, they belong to the order of insects and the family of bees. At present, about 50,000 species of bees have been identified, of which about 20,000 species belong to the family of bees and about 32,000 species belong to the family of wasps. There are about 700 species of wasps that are harmful to humans. According to the living habits and characteristics of wasps, the biggest harm when they sting people is that the bee needle pierces the human skin and releases bee venom into the human body. Therefore, as protective equipment to protect the safety of personnel handling beehives, how to ensure that the bee needle does not penetrate the fabric of the anti-bee clothing and pierce the human skin becomes the key to measuring the anti-stinging ability of the fabric. The anti-stinging performance of the material needs to be measured by safe and reliable test results. SUMMARY

[0004] The technical problem to be solved by the present application is to provide a cloth anti-stinging ability detection device which can simply and efficiently detect the anti-stinging ability of cloth.

As the experiment proceeds, the pressure applied by the needle to the cloth gradually increases, and when the pressure reaches the critical value that the cloth can withstand, the needle pierces the cloth, and the pressure applied by the needle to the cloth instantaneously decreases. The pressure fluctuation sensed by the pressure sensor is inputted to the MCU, and the puncture force (i.e. the peak value of the pressure) is displayed on the screen after processing and analysis by the MCU. The printer can print the obtained experimental data on paper for subsequent processing and analysis.

DETAILED DESCRIPTION

[0033] The present application will be further described below through specific embodiments:

[0034] As shown in Figure 1 , a cloth anti-bee stinging ability detection device, comprising a needle pricking mechanism 100, a clamp 200, a driving mechanism 300, a pressure sensor 400 and a control unit 500. The needle pricking mechanism 100 is connected to the driving mechanism 300, the clamp 200 is placed on the pressure sensor 400 located directly below the needle pricking mechanism 100, and the pressure sensor 400 is connected to the control unit 500.

[0035] The needle pricking mechanism 100 comprises a base plate 110, a needle holder 120 and a needle 130 for simulating a bee needle.

[0036] In combination Figure 1 and Figure 5The bottom of the needle seat 120 has a needle cavity 121 for placing the lancet 130, the lancet 130 extends into the needle cavity 121, and the needle seat 120 is provided with a fixing device for fixing the lancet 130. The fixing device includes two first bolts 122 symmetrically arranged on both sides of the needle seat 120. When the first bolt 122 is screwed in, the end of the first bolt 122 extends into the needle cavity 121 and abuts against the lancet 130 in the needle cavity 121, thereby fixing the lancet 130 in the needle cavity. When the first bolt 122 is unscrewed, the end of the first bolt 122 no longer abuts against the lancet 130, and at this time the lancet 130 can be conveniently removed. Thus the disassembly and assembly of the lancet 130 is achieved.

[0037] The structure of the lancet 130 is shown in Figure 9 The lancet 130 includes a needle body 131, a needle handle 132 sleeved on the needle body 131, and a limiting head 133 provided at the tail of the needle handle 132.

[0038] The needle body 131 is made of stainless steel, has a diameter of 0.18±0.008 mm, and a hardness (Vickers hardness) of 480HV 0.2kg -680HV 0.2kg to simulate the sting needle of bees. The needle handle 132 at least partially extends into the needle cavity 121, and the first bolt 122 can abut against the needle handle 132 extending into the needle cavity 121. The diameter of the limiting head 133 is greater than the diameter of the needle handle 132. When the fixing device is loose and the lancet 130 falls, the first bolt 122 can block the limiting head 133 to prevent the lancet 130 from falling out of the needle cavity 121.

[0039] In combination with Figure 2 and Figure 4 The substrate 110 is provided with a rotating seat 111, the needle seat 120 is provided with a rotating table 123, and the rotating table 123 is rotationally connected with the rotating seat 111. The outer circumferential surface of the rotating table 123 is uniformly provided with a plurality of positioning pin holes 124 in the circumferential direction, and the inner circumferential surface of the rotating seat 111 is provided with an elastic pin 112. The number of the positioning pin holes 124 is preferably four, and the included angle of every two adjacent positioning pin holes 124 with respect to the rotation center of the rotating table 123 is 90°. The elastic pin 112 is arranged at the lowest position of the inner circumferential surface of the rotating seat 111.

[0040] With such a structure, when the needle seat 120 is rotated to a vertical or horizontal position, the elastic pin 112 can be inserted into the positioning pin hole 124 to realize the positioning of the needle seat 120. The lancet 130 on the needle seat 120 can be kept in a vertical state for puncture action, or the needle seat 120 can be kept in a horizontal state for disassembly and assembly by the user.

[0041] As shown in Figure 2As shown, the driving mechanism 300 comprises a vertically arranged lead screw 320, a motor 310 connected to one end of the lead screw 320, and a sliding block 330 penetrating the lead screw 320 and engaging with the lead screw 320. During operation, the motor 310 drives the lead screw 320 to rotate, thereby driving the sliding block 330 to ascend and descend. The running speed of the sliding block 330 is 50-250 mm / min. The average speed accuracy is ±5%.

[0042] In combination Figure 2 and Figure 3 , the sliding block 330 is provided with a vertically arranged guide strip 340. The base plate 110 is provided with a C-shaped guide groove 113 matched with the guide strip 340. The guide strip 340 is inserted into the guide groove 113, so that the base plate 110 can slide and ascend and descend along the guide strip 340. The base plate 110 is provided with an adjusting nut 114, which, after being screwed into the base plate 110, can abut against the guide strip 340, so as to fix the base plate 110 at a specified height, thereby controlling the relative position between the needling mechanism 100 and the clamp 200.

[0043] In combination Figures 6 to 8 , the clamp 200 comprises a clamp seat 210, a clamp plate 220, a tensioning member 230, and an adjusting member 240. The clamp seat 210 and the clamp plate 220 are connected through the tensioning member 230. The adjusting member 240 is an eccentric wheel 241 arranged on the clamp seat 210. When the eccentric wheel 241 is rotated to a first position, the end of the eccentric wheel 241 far from the rotating shaft abuts against the clamp plate 220, thereby lifting the clamp plate 220 away from the clamp seat. At this time, the user can place the cloth between the clamp plate 220 and the clamp seat 210. When the eccentric wheel 241 is rotated to a second position, the end of the eccentric wheel 241 close to the rotating shaft faces the clamp plate 220. At this time, the eccentric wheel 241 is separated from the clamp plate 220, and the clamp plate 220 clamps the cloth placed between the clamp plate 220 and the clamp seat 210 under the tensioning action of the tensioning member 230.

[0044] The clamp plate 220 is annular and has a through hole 222 in the middle for the piercing needle 130 to penetrate. The clamp seat 210 is cylindrical and also has a through hole 222 in the middle for the piercing needle 130 to penetrate. The clamp plate 220 and the clamp seat 210 are concentrically arranged, and the diameter of the clamp plate 220 is greater than that of the clamp seat 210. When the eccentric wheel 241 rotates, it can abut against the outer ring of the clamp plate 220 protruding out of the clamp seat 210.

[0045] It should be noted that the adjusting member in the present application is not limited to the eccentric wheel, but can also be replaced by a cam structure, which can also achieve the effect of lifting the clamp plate. In addition, the adjusting member 240 is not limited to being arranged on the clamp seat 210, but can also be arranged on the clamp plate 220.

[0046] The tensioning member 230 comprises a second bolt 221 arranged on the clamping plate 220, a third bolt 211 fixed on the clamping seat 210, and a tension spring 231 connecting the second bolt 221 and the third bolt 211, and the tension spring 231 applies tension to the clamping plate 220, so that the clamping plate 220 is pressed on the clamping seat 210.

[0047] The control unit 500 comprises an MCU 510, a screen 520 and a printer 530, and the MCU 510 is electrically connected with the pressure sensor 400, the screen 520, the printer 530 and the motor 310 respectively.

[0048] The application also provides a cloth anti-bee-sting ability detection method based on the above mechanism, comprising the following steps.

[0049] Rotating the needle holder 120, so that the lancet 130 is in a vertical downward position;

[0050] Loosening the adjusting nut 114, so that the base plate 110 slides up and down relative to the guide strip 340, and the relative height of the needle pricking mechanism 100 and the clamp 200 is adjusted; after adjustment, the adjusting nut 114 is tightened;

[0051] Turning the eccentric wheel 241 to the first position, and the clamping plate 220 is pried open;

[0052] Extending the cloth 250 to be tested into the gap between the clamping plate 220 and the clamping seat 210;

[0053] Pressing the cloth 250 to be in a tension state, and turning the eccentric wheel 241 to the second position, at this time, the eccentric wheel 241 is no longer in contact with the clamping plate 220, and the clamping plate 220 is pressed against the cloth 250 between the clamping plate 220 and the clamping seat 210 under the tension of the tension spring 231;

[0054] The motor 310 is driven to rotate by the MCU 510, and the slider 330 is controlled to move downward at a speed of 100 mm / min, and the lancet 130 is lowered;

[0055] When the lancet 130 contacts the cloth to be tested, the lancet 130 applies pressure to the cloth, and the pressure sensor 400 senses the pressure change and transmits the pressure data to the MCU 510, and the MCU 510 processes the pressure data and displays it on the screen 520;

[0056] With the progress of the experiment, the pressure applied by the lancet 130 to the cloth 250 gradually increases, and when the pressure reaches the critical value that the cloth 250 can withstand, the lancet 130 pierces the cloth 250, and at this time, the pressure applied by the lancet 130 to the cloth 250 instantaneously decreases. The pressure sensor 400 senses the pressure fluctuation and inputs the corresponding pressure data to the MCU 510, and the MCU 510 processes and analyzes the puncture force (i.e. the peak value of the pressure) and displays it on the screen.

[0057] Repeat the above steps for multiple tests to obtain an average penetration force value;

[0058] The printer 530 prints the obtained experimental data on paper for subsequent processing and analysis.

[0059] In the above manner, the detection of the cloth's resistance to bee stings can be achieved, which is of great significance for the production of bee-proof clothing and the safety of honeycomb disposal personnel.

[0060] When the needle 130 is damaged or needs to be replaced with a different type of needle 130, the needle 130 can be replaced by the following steps:

[0061] Turn the needle holder 120 to the horizontal position;

[0062] Loosen the first bolt 122 and remove the needle 130 from the needle chamber 121;

[0063] Insert the new needle 130 into the needle chamber 121 and tighten the first bolt 122;

[0064] Turn the needle holder 120 so that the needle 130 on the needle holder 120 is in a vertical downward position. Thus, the disassembly and assembly of the needle are completed.

[0065] The use of a rotatable needle holder 120 allows the needle 130 to be placed horizontally and not to fall out of the needle chamber 121, so the user does not need to hold the needle 130 with one hand and twist the first bolt 122 with the other hand, making disassembly and replacement more convenient.

[0066] In summary, the cloth's resistance to bee stings detection device of the present application has the advantages of simple and flexible use, convenience and speed.

[0067] However, those skilled in the art in the technical field should realize that the above embodiments are only for illustration of the present application and are not intended to limit the present application, and any changes and modifications to the above described embodiments within the spirit and principles of the present application will fall within the scope of the claims of the present application.
