[0002] The tape locking structure of the tape measure on the market now is usually a plastic slider that slides downward. The slider is pushed by the fingers to press on the tape to achieve locking. This structure is relatively laborious, and after the tape measure has been used for a period of time, the slider is easily stuck or even stuck, making it inconvenient to use. Utility Model Content

[0003] In view of the deficiencies in the existing technology, the utility model provides a tape measure.

[0004] In order to achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a tape measure, including a shell, a tape, and a winding mechanism, the shell is provided with an opening, the opening is provided with a button, the button includes a pressing part and connecting parts extending into the tape measure on both sides of the pressing part, one end of the connecting part is rotatably connected to the shell through a first rotating shaft, and the two ends of the first rotating shaft are connected to the shell, the button is connected to a rotation reset member, the rotation reset member has elastic force, and can make the button return to its original position after the external force is eliminated after the force is rotated, the other end of the connecting part is provided with a slide groove, the slide groove is provided with a second rotating shaft, and the two ends of the second rotating shaft are connected to the shell, the connecting part is also connected to a third rotating shaft, and the tape passes through between the second rotating shaft and the third rotating shaft and then passes out of the shell, when the button is not pressed, the third rotating shaft relies on the elastic force of the rotation reset member and the second rotating shaft to lock the tape, when the button is pressed, the third rotating shaft rotates around the first rotating shaft together with the button, the third rotating shaft and the tape are out of contact, and the locking of the tape is released.

[0005] The rotation reset component is a torsion spring arranged on the first rotating shaft.

[0006] The second rotating shaft comprises a core shaft and a sleeve sleeved on the core shaft.

[0007] The housing comprises a lower shell and an upper shell.

[0008] The connecting portion is provided with a bayonet, and two ends of the third rotating shaft are connected to the connecting portion through the bayonet.

[0009] The beneficial effects of the utility model are as follows: the utility model locks the tape by means of the buttons, the first rotating shaft, the second rotating shaft, the third rotating shaft and other components. The tape can be unlocked simply by pressing the button, which is labor-saving and convenient to use. The rotating shaft is less susceptible to wear than the slider and has a longer service life.

[0015] like Figure 1-Figure 5 As shown, a tape measure comprises a housing 1, a tape 2, and a winding mechanism 3. The housing 1 is provided with an opening 4, and a button 5 is provided in the opening 4. The button 5 comprises a pressing portion 501 and connecting portions 502 extending into the tape measure on both sides of the pressing portion 501. One end of the connecting portion 502 is rotatably connected to the housing 1 through a first rotating shaft 6, and both ends of the first rotating shaft 6 are connected to the housing 1. The button 5 is connected to a rotation reset member, and the rotation reset member has elastic force, which can make the button 5 return to its original position after being rotated by force after the external force is eliminated. The other end of the connecting portion 502 A slide groove 503 is provided at the end, and a second rotating shaft 7 is provided in the slide groove 503, and the two ends of the second rotating shaft 7 are connected to the housing 1. The connecting portion 502 is also connected to a third rotating shaft 8, and the tape 2 passes through the second rotating shaft 7 and the third rotating shaft 8 and then passes through the housing 1. When the button 5 is not pressed, the third rotating shaft 8 relies on the elastic force of the rotation reset member and the second rotating shaft 7 to lock the tape 2. When the button 5 is pressed, the third rotating shaft 8 rotates around the first rotating shaft 6 with the button 5, and the third rotating shaft 8 and the tape 2 are out of contact, releasing the locking of the tape 2. The slide groove 503 plays a role of limiting during the rotation of the button 5 to prevent the button 5 from being pressed too much.

[0016] The rotation restoring member is a torsion spring 9 arranged on the first rotating shaft 6 .

[0017] The second rotating shaft 7 comprises a core shaft 701 and a sleeve 702 sleeved on the core shaft 701. The second rotating shaft 7 is made into a split structure for easy assembly.

[0018] The housing 1 comprises a lower housing and an upper housing. A bayonet 504 is provided on the connecting portion 502 , and two ends of the third rotating shaft 8 are connected through the bayonet 504 and the connecting portion 502 .

[0019] The above shows and describes the basic principle, main features and advantages of the utility model. The technicians in this industry should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, simple changes and substitutions by ordinary technicians in this field are within the protection scope of the utility model.
