[0021] The principles and features of the present utility model will be described below in conjunction with the accompanying drawings. The examples given are only used to explain the present utility model and are not intended to limit the scope of the present utility model.

[0022] This embodiment provides a skin penetration experiment reaction detection device, which is used for experiments to test the skin absorption ability of substances such as cosmetics and drugs. The adjusting mechanism 2 can be used to conveniently adjust the height of the detection equipment body 206, so as to facilitate the use by personnel of different heights, avoid discomfort caused by the detection equipment body 206 being too high or too low during use by the detection personnel, and at the same time, the angle of the detection equipment body 206 can also be changed, and the angle of the detection equipment body 206 can be adjusted according to the habits of the users, further improving the adaptability of the skin penetration experiment reaction detection device and increasing the use effect of the device.

[0023] Refer to Figure 1 and Figure 2 As shown in the figure, a skin penetration experiment reaction detection device includes a base plate 1. An adjusting mechanism 2 is arranged above the base plate 1. The adjusting mechanism 2 includes a support block 201. The bottom surface of the support block 201 is fixedly connected to the upper surface of the base plate 1. Reinforcement blocks 210 are fixedly connected to both the left and right side surfaces of the support block 201. The bottom surface of each reinforcement block 210 is fixedly connected to the upper surface of the base plate 1. The reinforcement blocks 210 can increase the contact area between the support block 201 and the base plate 1, enhance the firmness of the connection between the two, avoid the possibility of breakage at the connection after long-term use, and increase the durability of the device.

[0024] Refer to Figure 2 As shown in the figure, a threaded rod 202 is rotatably connected inside the support block 201. An auxiliary bearing 211 is sleeved on the outer surface of the threaded rod 202. The auxiliary bearing 211 is embedded in the support block 201. The auxiliary bearing 211 can reduce the friction generated when the threaded rod 202 rotates, make the threaded rod 202 more sensitive when rotating, and at the same time, can also reduce the wear rate of the threaded rod 202 and increase the service life of the threaded rod 202.

[0025] Refer to Figure 2, a auxiliary ring 212 is fixedly connected to the top end of the threaded rod 202, and a turning handle 213 is fixedly connected to the outer surface of the auxiliary ring 212. By using the cooperation of the auxiliary ring 212 and the turning handle 213, the convenience of rotating the threaded rod 202 when needed can be increased. By applying force to the auxiliary ring 212 through the turning handle 213, the threaded rod 202 can be driven to rotate.

[0026] Refer to Figure 2 , a lifting block 203 is threadedly connected to the outer surface of the threaded rod 202. The lifting block 203 is slidably connected to the inside of the support block 201. A stabilizing block 214 is fixedly connected to the left side surface of the lifting block 203. The stabilizing block 214 is slidably connected to the inside of the support block 201. The stabilizing block 214 can move simultaneously with the lifting block 203, and use the friction generated on the support block 201 during its movement to improve the stability of the lifting block 203 during movement, increasing the stability of the device.

[0027] Refer to Figure 2 and Figure 3 , a auxiliary block 204 is fixedly connected to the front surface of the lifting block 203. A transmission rod 205 is rotatably connected to the inside of the auxiliary block 204. A detection device body 206 is fixedly connected to the end of the transmission rod 205 away from the auxiliary block 204. A rotating bearing 215 is sleeved on the outer surface of the transmission rod 205. The rotating bearing 215 is embedded in the inside of the auxiliary block 204. The rotating bearing 215 can reduce the friction generated when the transmission rod 205 rotates, make the transmission rod 205 more sensitive when rotating, and also reduce the wear speed of the transmission rod 205 when rotating, increasing the durability of the transmission rod 205.

[0028] Refer to Figure 4 , a auxiliary gear 207 is fixedly connected to the outer surface of the transmission rod 205. A pull rod 208 is slidably connected to the inside of the auxiliary block 204. A retaining ring 216 is fixedly connected to the left end of the pull rod 208. A pulling handle 217 is fixedly connected to the left end of the retaining ring 216. By relying on the cooperation of the retaining ring 216 and the pulling handle 217, a good force application point can be provided for the pull rod 208. By pulling the pulling handle 217, the retaining ring 216 and the pull rod 208 can be driven to move, increasing the convenience when using the device.

[0029] Refer to Figure 4 , a limiting block 209 is fixedly connected to the right end of the pull rod 208. The limiting block 209 is engaged with the auxiliary gear 207. A auxiliary spring 218 is sleeved on the outside of the pull rod 208. The left end of the auxiliary spring 218 is fixedly connected to the inner wall of the auxiliary block 204. The right end of the auxiliary spring 218 is fixedly connected to the inner wall of the pull rod 208. The auxiliary spring 218 can continuously apply a thrust to the pull rod 208 by using its own telescopic ability, making the pull rod 208 achieve the effect of automatic reset, and at the same time can also prevent the pull rod 208 from moving.

[0030] Working principle: When in use, first connect the power supply of the detection device body 206. When it is necessary to detect the skin penetration reaction, place the application site inside the detection device body 206. When it is necessary to adjust the height of the detection device body 206, rotate the rotary handle 213 to rotate the auxiliary ring 212, so that it drives the threaded rod 202 to rotate forward or backward. The auxiliary bearing 211 can increase the sensitivity of the threaded rod 202 during rotation, and then the lifting block 203 moves up and down in the support block 201. The stabilizing block 214 can improve the stability of the lifting block 203 during movement, and then the detection device body 206 moves simultaneously, realizing the ability to adjust the detection device body 206 according to the height of the tester. When it is necessary to adjust the angle of the detection device body 206, pull the pull handle 217, so that the retaining ring 216 drives the pull rod 208 to move, and then the limiting block 209 moves. At the same time, the auxiliary spring 218 will be compressed. When the limiting block 209 moves, it can release its meshing relationship with the auxiliary gear 207, and then the transmission rod 205 is in an unobstructed state. At this time, the angle of the detection device body 206 can be conveniently changed through the rotational connection and cooperation between the transmission rod 205 and the auxiliary block 204. When adjusted to the appropriate angle, release the pull handle 217, and use the resilience of the auxiliary spring 218 to push the transmission rod 205 to reset and make the limiting block 209 reset, so that the limiting block 209 meshes with the auxiliary gear 207 again, avoiding the rotation of the detection device body 206 after adjustment, and effectively increasing the applicability of the skin penetration experiment reaction detection device.

[0031] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
