The specific meanings of the above terms in the present invention can be understood according to specific situations by those of ordinary skill in the art.
As shown in fig. 1 to fig. 1, the present invention provides a specific embodiment of a mechanical disposable indication structure, which comprises a bottom plate 1, a rotation control plate 2 rotatably disposed at one side of the back surface of the bottom plate 1, and a pushing part 3 disposed below the rotation control plate 2;
the rotary control plate 2 comprises a rotary disc 201 which is rotatably installed on the bottom plate 1, the top of the rotary disc 201 is provided with an elastic sheet 202 in a clockwise connection mode, a distance which allows the elastic sheet 202 to approach towards the edge of the rotary disc 201 is formed between a deformation part of the elastic sheet 202 and the rotary disc 201, a clamping gap 203 is formed in the body of the rotary disc 201 at the free end of the deformation part of the elastic sheet 202, a clamping block 204 is arranged above the deformation part of the elastic sheet 202, a locking surface 206 is arranged on the upper surface of the elastic sheet 202 which is close to the clamping block 204 in the clockwise direction, a push block 205 is connected to the outer edge of one side of the middle lower part of the rotary disc 201, and the push block 205 is pushed upwards to enable the rotary disc 201 to rotate anticlockwise;
the upper part of one side of the back of the bottom plate 1 is provided with a clamping column 101, the elastic sheet 202 enables the clamping column 101 to be clamped on one side of the clamping block 204 in the clockwise direction by means of self elasticity, the clamping column 101 is tightly pressed and matched with the locking surface 206 in a locking way, the clamping column 101 can be separated from the clamping block 204 and the locking surface 206 by rotating the turntable 201 anticlockwise until the clamping column is clamped into a clamping gap 203 between the elastic sheet 202 and the turntable 201 body, the bottom plate 1 corresponding to the turntable 201 body is provided with a display window 102, and the rotating turntable 201 enables the display window 102 on one side of the front of the bottom plate 1 to display different marks;
the pushing portion 3 can push the pushing block 205 to move upward.
In the present embodiment, as shown in fig. 2, when the pushing portion 3 is not pushed, the elastic sheet 202 makes the locking pin 101 be locked on one side of the locking block 204 in the clockwise direction by its own elasticity, and the locking pin 101 is tightly pressed and locked with the locking surface 206, and the display window 102 on one side of the front surface of the bottom plate 1 displays an unused mark; after the pushing part 3 is pushed, the pushing part 3 pushes the pushing block 205 upwards, the rotating disc 201 rotates anticlockwise, the elastic piece 202 also rotates anticlockwise along with the rotating disc 201, the elastic piece 202 is further pressed by the clamping column 101 to be close to the rotating disc 201, the pushing part 3 continues to push the pushing block 205 upwards until the locking surface 206 of the elastic piece 202 is separated from the clamping column 101, the clamping column 101 is clamped in the clamping gap 203 between the elastic piece 202 and the rotating disc 201, and at the moment, the display window 102 on one side of the front surface of the bottom plate 1 displays the used mark. After the locking pin 101 is locked in the locking notch 203, the rotating plate 201 cannot be reset or swing back and forth freely because the clockwise direction is limited by the rotating plate 201 and the counterclockwise direction is limited by the elastic piece 202. The user can judge the use condition according to the identifier correspondingly displayed by the display window 102, and the indication structure can obviously provide the safety of wearing the gas mask.
The use identifier used in this embodiment is a color change, and certainly, the user may also use other identifiers such as characters according to actual needs.
Specifically, as shown in fig. 2 and 4, an arc notch 207 is formed in the outer edge of the other side of the middle-lower portion of the rotating disc 201, the rotating disc 201 before rotating causes the display window 102 on the front side of the bottom plate 1 to display a color, and the rotating disc 201 after rotating causes the display window 102 on the front side of the bottom plate 1 to correspond to the arc notch 207 and display a blank. When the pushing part 3 is not pushed, the rotating disc 201 is opposite to the display window 102, and the display window 102 on the front side of the bottom plate 1 is red; when the pushing portion 3 is pushed to make the locking pillar 101 locked in the locking notch 203 between the elastic sheet 202 and the body of the rotating disc 201, the display window 102 on the front side of the bottom plate 1 corresponds to the arc notch 207 and displays a blank (the red color disappears), thereby completing the indication of the disposable use. In the embodiment, the indication color displacement is forced by external force, so that the user can achieve the purpose of use indication according to the color change of the display window 102, and the function of indication before and after the canister is used is realized.
Specifically, when the pushing portion 3 pushes the pushing block 205 upward, the pushing portion 3 moves inward with respect to the bottom surface of the pushing block 205 (as shown in fig. 2 and 4). In this embodiment, in order to facilitate the pushing part 3 to push the pushing block 205, the bottom surface of the pushing block 205 is a horizontal plane (as shown in fig. 2), or the bottom surface of the pushing block 205 is an inclined plane to facilitate the relative movement of the pushing part 3.
The embodiment further provides a specific implementation manner of the pushing portion 3, as shown in fig. 2 and 4, that is, the pushing portion 3 includes a pushing rod 301 and a pushing plate 302 connected to the pushing rod 301, two guiding holes 305 are formed in the pushing plate 302 along the up-down direction, the two guiding holes 305 are respectively located at two sides of the pushing plate 302, a guiding post 103 in guiding sliding fit with the guiding hole 305 is correspondingly arranged at one side of the back surface of the bottom plate 1, and pushing the pushing rod 301 can enable the guiding hole 305 to move upwards along the guiding post 103, and enable the pushing plate 302 to push the pushing block 205. In the present embodiment, when the push portion 3 is not pushed, the guide posts 103 are located above the respective guide holes 305; when the pushing part 3 is pushed, the guide posts 103 are located below the corresponding guide holes 305.
Furthermore, a limiting column 104 is arranged on one side of the back surface of the bottom plate 1 above the pushing part 3, and a return spring 303 is connected between the limiting column 104 and the pushing part 3. When the pushing part 3 is pushed, the return spring 303 between the pushing part 3 and the limiting post 104 is compressed, the clamping post 101 is clamped in the clamping gap 203 between the elastic sheet 202 and the turntable 201 body, and at this time, after the display window 102 displays the use identifier, the return spring 303 reacts to make the pushing part 3 move down to the initial position. This can improve the user's use sensitivity.
As shown in fig. 2 and 4, in order to reduce the volume of the component and improve the compactness of the layout of the component, the upper portion of the push plate 302 between the two guide holes 303 is provided with a notch 304. The return spring 303 may now be disposed in the middle of the notch 304.
As shown in fig. 2 and 4, the locking surface 206 is a planar structure. Of course, other structures of the locking surface 206 for limiting the elastic piece 202 from swinging back and forth along the clamping column 101 can be adopted according to practical situations.
Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; while the invention has been described in detail and with reference to the foregoing embodiments, it will be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; and these modifications or substitutions do not depart from the spirit of the corresponding technical solutions of the embodiments of the present invention.
