[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] All electronic components in this application are controlled by an external controller.
[0024] Example 1
[0025] Please refer to Figure 1-6 As shown, this utility model provides a portable measuring marker, including a main housing 1, a tape measure 2 inside the main housing 1, an opening for the tape measure 2 to pass through, a secondary housing 3 on one side of the main housing 1, a sleeve 4 inside the secondary housing 3, a marking assembly inside the sleeve 4, the marking assembly including a sleeve 5 installed inside the sleeve 4, a pressing post 6 inside the sleeve 5, a pressing part 7 for applying the mark on the pressing post 6, a spring-loaded assembly for resetting the pressing post 6 on the sleeve 5, and a rotating assembly for adjusting the marking direction on the sleeve 5; the tape measure 2 is provided with a clamping plate 8, and a hanging ring 9 is provided on one end of the tape measure 2 and the clamping plate 8 respectively.
[0026] The measuring tape 2 can be purchased directly from the market. The main housing 1 is the outer shell of the measuring tape 2. The secondary housing 3 is fixed to one side of the main housing 1. The sleeve 4 is fixed inside the secondary housing 3. The sleeve 5 can rotate inside the sleeve 4. The pressing post 6 is located inside the sleeve 5. The pressing part 7 is located at one end of the pressing post 6. The pattern to be marked can be engraved on the pressing part 7. The pressing part 7 can be set with an appropriate pattern. The pattern can be printed at the target position, which can make the marking more accurate and avoid confusion with other markings. The clamp 8 is clamped on the measuring tape 2. The distance between the clamp 8 and the end of the measuring tape 2 is the same as the distance between the outlet of the measuring tape 2 and the pressing post 6. With this setting, the measured length can be seen by checking the verticality of the measuring tape 2 at the opening. The hanging ring 9 can conveniently fix the end of the measuring tape 2.
[0027] Specifically, the rebound assembly includes an anti-rotation block 10 disposed on the pressing post 6, an anti-rotation groove 11 provided on the inner wall of the sleeve 5, and a spring 19 provided inside the anti-rotation groove 11 and on one side of the anti-rotation block 10; a guide rod 12 is provided inside the anti-rotation groove 11, and the guide rod 12 is slidably connected to the anti-rotation block 10. The anti-rotation block 10 is fixedly connected to the pressing post 6, the anti-rotation groove 11 is opened on the inner wall of the sleeve 5, the anti-rotation block 10 is slidably connected to the anti-rotation groove 11, the guide rod 12 is fixedly connected in the anti-rotation groove 11, and can guide the anti-rotation block 10. The spring 19 can reset the pressing post 6, which facilitates the protection of the pressing part 7.
[0028] The rotating assembly includes multiple spring pieces 13 fixed on the outer wall of the sleeve 5. The inner wall of the sleeve 4 is provided with a groove 14 that cooperates with the spring pieces 13. The spring pieces 13 are bent to one side, and the groove 14 is opened on the inner wall of the sleeve 4. The end of the spring 19 can abut in the groove 14, so that the sleeve 5 can rotate in one direction. When the end of the spring piece 13 abuts between two grooves 14, the tension of the spring 19 will act on the sleeve 4. Without the action of external force, the pressing post 6 can be fixed, which makes it convenient to adjust the direction of the pressing part 7 and make the direction of the mark correct.
[0029] Based on the above embodiments, specifically, the other end of the pressing column 6 is provided with a knob 15 for convenient rotation of the sleeve 5. The knob 15 has a horizontal bead 16 in the middle. The sub-shell 3 is provided with a scale for viewing the marked angle. The knob 15 is located at the other end of the pressing column 6, which facilitates the rotation of the pressing column 6. The horizontal bead 16 can be purchased directly from the market. The scale is engraved on the sub-shell 3, which can make the placement of the main shell 1 more accurate and avoid tilting.
[0030] Working principle: When measurement is required, fix the hanging ring 9 at one end of the tape measure 2 to one end, and then pull the tape measure 2 out to the target position. When marking is required, place the main housing 1 on the surface to be marked, and then straighten the pressing part 7 by rotating the knob 15. During the rotation of the knob 15, the level bead 16 and the scale can be used for correction. After the position is determined, press down the pressing column 6 to make the pressing part 7 extend out of the secondary housing 3 and mark the surface to be marked.
[0031] More specifically, a cover plate 17 for protecting the pressing part 7 is provided on one side of the pressing column 6. The cover plate 17 is provided with ink pad 18. The cover plate 17 is snapped onto the pressing column 6 and can protect the pressing part 7. The ink pad 18 can replenish the ink on the pressing part 7.
[0032] The contents not described in detail in this specification are existing technologies known to those skilled in the art.
[0033] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
