[0002] A tape measure is a commonly used tool in daily life. What people often see is a steel tape measure, which is commonly used in construction and decoration and is also one of the essential tools for families. An ink pot is a very common tool in the traditional Chinese woodworking industry and is usually used for measurement and house construction. In actual working scenarios, the ink pot and the tape measure are usually used in cooperation, that is, the tape measure is used for measurement and the ink pot is used for marking and positioning.
[0003] Chinese Patent CN20817113U discloses a multi-functional tape measure, which can not only measure distances during use but also has a marking function. It has richer functions, is more flexible and convenient to use, can measure in a darker environment, and has a wide range of applications. However, the assembly of the ink pot and the tape measure in this structure is complex and the cost is high. Since the ink pot assembly is clamped on the head of the tape measure, the ink pot and the tape measure need to be operated simultaneously during actual use, and their assembly is complex and not convenient to operate.

[0014] The following further explains and illustrates the present utility model with reference to the accompanying drawings and specific embodiments.
[0015] Embodiment: As shown in the figure, a tape measure with an ink box function according to the present utility model includes a housing 1, a tape measure assembly 2, and an ink box assembly 3. The housing 1 includes a tape measure housing 4 and an ink box housing 5 that are snap-connected. The tape measure assembly 2 is located inside the tape measure housing 4, and the ink box assembly 3 is located inside the ink box housing 5. The tape measure assembly 2 includes a tape 21, a tape hook 22, a tape measure wheel 23, a reel 24, and a winding spring 25. The tail end of the tape 21 is fixedly connected to the winding spring 25. After being wound around the tape measure wheel 23, the head end is fixedly connected to the tape hook 22. The reel 24 is installed in the middle of the two side walls of the tape measure housing 4 and the ink box housing 5. The winding spring 25 is wound around the reel 24 and is snap-connected to the reel 24. The tape hook 22 is located at the front end of the housing 1. The ink box assembly 3 includes an ink storage box 31, an ink box switch 32, a hook 33, an ink box line 34, and an ink box line wheel 35. The ink box line wheel 35 is installed on the reel 24. The ink box line 34 is wound around the ink box line wheel 35, and one end is fixed to the ink box line wheel 35, and the other end is connected to the hook 33 located outside the ink box housing 5. An ink storage box 31 in contact with the ink box line 34 is also provided inside the ink box housing 5 near the hook 33. A pressable ink box switch 32 is provided at the corresponding position of the ink box housing 5. The hook 33 is located at the rear end of the housing 1. A fastening device 6 connected to the reel 24 is further provided on the ink box reel. The fastening device 6 drives the reel 24 to rotate unidirectionally.
[0016] The center of the fastening device 6 is provided with a mounting hole connected to the reel 24, and a group of evenly distributed arc-shaped pawls 7 are provided on the outside. The arc-shaped pawls 7 are arranged in the same direction and are snap-connected to the ink box line wheel 35, so that the fastening device 6 can only rotate unidirectionally at the ink box line wheel 35 with the reel 24 as the rotation center.
[0017] A tape measure locking button 8 is further provided on the front side of the tape measure housing 4 to lock the tape 21 in any state on the tape measure housing 4.
[0018] A connecting notch 9 is provided on the end face of the reel 24. One end of the winding spring 25 is snap-connected in the connecting notch 9. When the reel 24 rotates, it drives the winding spring 25 to wind up.
[0019] See Figure 3, specifically in use, taking the example of the coil spring 25 being wound counterclockwise around the reel 24. When using the tape measure alone, in the initial state, the locking button of the tape 21 is closed, and the tape 21 can rotate freely. Pull the tape hook 22 to the right, and the tape hook 22 will drive the tape 21 to be pulled out to the right. During this process, the tape measure wheel 23 connected to the tape 21 rotates accordingly, causing the internal coil spring 25 to gradually tighten and store energy. After releasing the tape hook 22, the coil spring 25 will drive the tape measure wheel 23 to rotate under the force, causing it to reset. Specifically, when pulling out to the right, the tape measure wheel 23 rotates counterclockwise, which will drive the coil spring 25 counterclockwise. During this process, the reel 24 remains stationary, and the coil spring 25 will gradually tighten around the reel 24. At this time, the coil spring 25 stores energy. After releasing the tape hook 22, the external force on the tape 21 and the tape measure wheel 23 disappears. At this time, the coil spring 25 begins to release torque, driving the tape measure wheel 23 to rotate clockwise, thereby driving the tape 21 to rotate clockwise and winding it around the tape measure wheel 23 to reset until the tape hook 22 contacts the housing 1 for limiting.
[0020] Since in the initial state, it is necessary to make the coil spring 25 have enough torque to drive the tape measure wheel 23 to drive the tape 21 to wind, during assembly, after the coil spring 25 is connected and positioned with the reel 24, manually rotate the fastening device 6 to make the coil spring 25 wind around the reel 24 and store a part of the energy. Specifically, it is necessary to rotate the fastening device 6 clockwise, driving the reel 24 to also rotate clockwise, and the coil spring 25 remains stationary. Therefore, it can be regarded as winding the coil spring 25 counterclockwise around the reel 24 relatively. In the initial state, the coil spring 25 only needs to be wound partially to provide part of the torque so that when the tape 21 is pulled out, there is a winding margin. In the extreme state, when the coil spring 25 is completely wound and tightened around the reel 24, since the coil spring 25 cannot be tightened further and the tape measure wheel 23 has no rotation space either, at this time the tape 21 is in the maximum pulled-out state and the stored energy is the largest.
[0021] Similarly, when using the ink pot alone, pulling the ink pot line 34 to the left will drive the ink pot line wheel 35 to rotate clockwise, thereby driving the rotating shaft reel 24 to rotate clockwise. Since the tape measure assembly 2 remains stationary, it can be regarded as the coil spring 25 being stationary, and the rotation of the reel 24 can be regarded as the coil spring 25 being wound counterclockwise around the reel 24. At this time, the coil spring 25 will also be tightened and store energy. After releasing the ink pot line 34, the torque is released and the reel 24 rotates counterclockwise to reset, causing the ink pot line 34 to wind around the ink pot line wheel 35 for reset.
[0022] During use, since the tape measure assembly 2 drives the coil spring 25 to rotate and the ink pot assembly 3 drives the reel 24 to rotate, to a certain extent, the tape measure and the ink pot line can be used simultaneously for marking. Before the tightening margin of the coil spring 25 and the reel 24, both can be used simultaneously and automatically reset without interference with each other.
[0023] The utility model is connected with a clock spring through a tape measure assembly, generates torsion by winding on a reel, and realizes the automatic retraction of the tape when it is pulled out. At the same time, the utility model is connected with an ink pot assembly through the reel, and realizes the automatic retraction of the ink pot line by generating torsion between the rotation of the reel and the clock spring. The two share one reel and one clock spring, can realize the functions of the tape measure and the ink pot simultaneously, and can automatically retract after use, with a simple structure and convenient use.
[0024] The above are only used to illustrate the technical solution of the utility model rather than to limit it. Any other modifications or equivalent replacements made by those of ordinary skill in the art to the technical solution of the utility model shall be covered within the scope of the claims of the utility model as long as they do not depart from the spirit and scope of the technical solution of the utility model.
