Description

Technical Field

[0001] This application relates to a measuring tape. Background Technology

[0002] A measuring tape is a widely used length measuring tool. It can measure both straight and curved lengths, such as the length of an object in a straight line or its circumference. Measuring the circumference requires wrapping the tape around the object. However, in existing technology, the tape end must be held at all times to prevent it from automatically retracting into the tape. Furthermore, when measuring the circumference, the tape end after one full wrap needs to be as close to the tape as possible to ensure accuracy. However, the small measuring angle between the tape's outer casing and the object limits the operating space, increasing the difficulty of the measurement. Summary of the Invention

For those skilled in the art, the specific meaning of the above terms can be understood according to the specific circumstances.

[0048] The accompanying drawings illustrate one or more examples of this application. The detailed description uses numerical and alphabetic designations to refer to features in the drawings. Similar or analogous designations in the drawings and description have been used to refer to similar or analogous parts of this application. As used herein, the terms “first,” “second,” and “third,” etc., are used interchangeably to distinguish one component from another and are not intended to indicate the location or importance of individual components.

[0049] like Figure 1 , Figure 3 and Figure 7 As shown, according to an embodiment of this application, a measuring tape is provided, comprising a housing 10 with an opening 122, and a measuring tape 20 disposed within the housing 10. The measuring tape 20 can be pulled out from or retracted into the housing 10 through the opening 122. The housing 10 includes a first housing 11 and a second housing 12, with the measuring tape 20 disposed between the first housing 11 and the second housing 12. A receiving compartment 121 is provided within the second housing 12, and at least a portion of the measuring tape 20 is confined within the receiving compartment 121.

[0050] like Figure 7As shown, in some embodiments, a reel 50 is provided inside the receiving compartment 121. The first end of the tape 20 is connected to the rotating shaft 51 and wound around the outside of the reel 50. The reel 50 is circularly provided with the rotating shaft 51 and is rotatably connected to the rotating shaft 51. One end of the rotating shaft 51 is fixedly connected to the second housing 12. A helical spring 40 is sleeved on the rotating shaft 51. One end of the helical spring 40 is connected to the rotating shaft 51, and the other end is connected to the reel 50. Pulling the tape 20 outward and driving the reel 50 to rotate allows the helical spring 40 to accumulate energy. After the external force pulling the tape 20 is removed, the helical spring 40 releases energy to drive the reel 50 to rotate in the opposite direction, so that the tape 20 is rewound onto the reel 50. A braking structure 60 is installed on the outer casing 10. When the tape 20 is pulled out of or retracted into the receiving compartment 121, it will pass through the braking structure 60. The braking structure 60 can restrict or release the movement of the measuring belt 20 within it, including prohibiting movement of the measuring belt 20 or allowing it to move freely. The braking structure 60 includes a rotatable roller 61 and a brake shaft 62, which are parallel to each other, with the measuring belt 20 passing between them. When the roller 61 and brake shaft 62 are close together and tightly fitted, the measuring belt 20 is restricted and cannot move. When the roller 61 and brake shaft 62 are separated and there is sufficient clearance, the measuring belt 20 can move freely between them.

[0051] like Figures 1 to 3 As shown, in order to facilitate the measurement of the perimeter of the object to be measured, the measuring tape of this application also includes a fastening assembly 30. The fastening assembly 30 includes a first fastener 31 and at least one second fastener 32. The first fastener 31 is disposed at the second end of the measuring tape 20 and is fixedly connected to the measuring tape 20. The second fastener 32 is fixedly disposed on the housing 10. The first fastener 31 and one of the second fasteners 32 can be selectively engaged or disengaged.

[0052] like Figure 2 and Figure 3 As shown, in some embodiments, the housing 10 includes a first sidewall 101 and a second sidewall 102 disposed adjacent to each other, and an opening 122 of the housing 10 is disposed at the intersection of the first sidewall 101 and the second sidewall 102. Two second fasteners 32 are mounted on the housing 10, one second fastener 32a is disposed at the end of the first sidewall 101 near the opening 122, and the other second fastener 32b is disposed at the end of the second sidewall 102 near the opening 122.

[0053] In some embodiments, the second fastener 32 includes a magnetic sheet 321, which may be made of a permanent magnet material. Taking the magnetic sheet 321 fixedly mounted on the second sidewall 102 as an example... Figure 4 As shown, in another embodiment, a cavity 1231 is provided at one end of the second sidewall 102 near the opening 122, and the magnetic sheet 321 is disposed within the cavity 1231; Figure 5As shown, in one embodiment, a groove 1232 is provided at the end of the second sidewall 102 near the opening 122, and the magnetic piece 321 is embedded in the groove 1232. The first fastener 31 includes a magnetically attractive housing made of a magnetically attractive material; or, at least the side of the housing facing the magnetic piece 321 is made of a magnetically attractive material; or, a component made of a magnetically attractive material is provided inside the housing. The magnetically attractive material includes at least one of iron, cobalt, nickel, and their alloys; of course, the magnetically attractive material can also be a permanent magnet material. When the first fastener 31 approaches the second fastener 32, under the action of magnetic attraction, the first fastener 31 can be selectively attracted to the outer shell 10. In other embodiments, the first fastener 31 and the second fastener 32 can be made of interchangeable materials.

[0054] The second fastener 32 also includes a panel 325, which is disposed on the outer side of the housing 10, with one end of the panel 325 located at the edge of the opening 122 of the housing 10. In this embodiment, the panel 325 is part of the housing 10; however, the panel 325 can also be disposed as a separate component on the outer side of the housing 10. When the first fastener 31 approaches the second fastener 32, the first fastener 31 can be magnetically attracted to the panel 325. The outer contours of the side of the panel 325 facing the first fastener 31 and the side of the first fastener 31 facing the panel 325 cooperate with each other to make the fit between the first fastener 31 and the panel 325 tighter.

[0055] like Figure 5 As shown, in some embodiments, the surface of panel 325 is flat, and the position of the first fastener 31 adsorbed on panel 325 has a certain degree of randomness. During measurement, it may be necessary to adjust the position of the first fastener 31 on panel 325 multiple times to meet the measurement conditions. To solve the problem of quickly positioning the first fastener 31 on panel 325, such as... Figure 5 , Figures 8 to 10 As shown, in one embodiment, the panel 325 has a limiting groove 322 recessed into the outer casing 10. Correspondingly, the first fastener 31 has an outwardly protruding limiting block 311 on the side facing the second fastener 32. The limiting block 311 engages with the limiting groove 322 to limit the position of the first fastener 31 on the panel 325. In another embodiment, the panel 325 has a limiting block 311 protruding outward from the outer casing 10, and correspondingly, the first fastener 31 has an inwardly recessed limiting groove 322 on the side facing the second fastener 32, achieving the same limiting effect. Alternatively, in other embodiments, the panel 325 has a groove recessed into the outer casing 10, and at least a portion of the first fastener 31 on the side facing the second fastener 32 is engaged in the groove, also achieving the same limiting effect.

[0056] When measuring the perimeter of the object 200, taking one measurement method as an example, such as... Figure 11 As shown, the first fastener 31 can be pulled first to extend the measuring tape 20 to a sufficient length. Then, the length extended by the measuring tape's braking structure 60 is locked. Finally, the first fastener 31 is wrapped around the object to be measured 200 and attached to the panel 325. Figure 12 As shown, the locking mechanism 60 releases the tape 20, and the tape 20 retracts under the drive of the coil spring 40 until it is taut. At this point, the circumference of the object 200 can be obtained by reading the measurement value of the tape 20. During the retraction of the tape 20, due to the limited magnetic attraction between the first fastener 31 and the second fastener 32, the first fastener 31 may detach from the panel 325 when the tape 20 is taut. Alternatively, during measurement, improper operation may cause the first fastener 31 to detach from the panel 325. For example, the tape measure may slip from the hand, or excessive force may be applied when holding the tape measure. To solve this problem, in some embodiments, the first fastener 31 has a buckle 312 on the side facing the second fastener 32. Correspondingly, the panel 325 has an inwardly recessed groove 324, and the buckle 312 can selectively embed into and engage with the groove 324. The first fastener 31 can be restrained on the outer casing 10 through the cooperation between the buckle 312 and the groove 324.

[0057] like Figures 13 to 15 As shown, in some embodiments, the buckle 312 includes a hook portion 3121 opening towards the tape 20, and the buckle groove 324 includes a hook groove portion 3241 extending towards the opening 122 of the outer casing 10. When the buckle 312 is engaged with the buckle groove 324, the buckle 312 can be pushed into the buckle groove 324 along the opening of the buckle groove 324 towards the opening 122 of the outer casing 10, so that the hook portion 3121 of the buckle 312 is completely embedded in the hook groove portion 3241 of the buckle groove 324. After the buckle 312 is embedded in the buckle groove 324, the first fastener 31 is attracted to the outer casing 10 under the action of magnetic force, so that the buckle 312 can be retained in the buckle groove 324. During measurement, the tension on the first fastener 31 mainly comes from one side of the measuring tape 20. The direction of force on the hook portion 3121 of the buckle 312 is restricted by the hook groove portion 3241 of the buckle groove 324, preventing the first fastener 31 from detaching from the outer casing 10. When the measurement is completed or when it is necessary to remove the first fastener 31 from the outer casing 10, the first fastener 31 can be removed in the opposite direction to when the buckle 312 and the buckle groove 324 are engaged.

[0058] like Figure 15 and Figure 16As shown, in order to allow the hook portion 3121 to quickly engage with the hook groove portion 3241, and also to facilitate the quick removal of the first fastener 31 from the fastening groove 324, in some embodiments, the fastening groove 324 is provided with a slope 3242, which is located at opposite ends of the hook groove portion 3241. The slope 3242 extends along the opening of the fastening groove 324 toward the inside of the fastening groove 324 and toward the opening 122 of the outer casing 10. Correspondingly, the buckle 312 is provided with a guide surface 3122, which is located at opposite ends of the buckle 3121, and the slope of the guide surface 3122 is the same as the slope of the slope 3242. During the process of the inverted buckle 312 being inserted into the buckle groove 324, the guide surface 3122 and the slope surface 3242 are in contact with each other and slide in the direction of arrow E, which allows the inverted buckle 312 to be quickly and accurately inserted into the designated position of the buckle groove 324, thereby achieving the purpose of quickly placing the first fastener 31. During the process of removing the inverted buckle 312 from the buckle groove 324, the first fastener 31 is pushed in the direction away from the opening 122 of the outer shell 10. Under the guidance of the guide surface 3122 and the slope surface 3242, the inverted buckle 312 can quickly disengage from the buckle groove 324 in the opposite direction of arrow E, thereby achieving the purpose of quickly removing the first fastener 31.

[0059] In addition, such as Figure 4 , Figure 10 and Figure 15 As shown, in some embodiments, a patch 323 is attached to the surface of the panel 325. When the first fastener 31 contacts the panel 325 under magnetic attraction, a sound may be produced. The patch 323 can be made of a material with cushioning properties, such as silicone or TPU, to reduce the impact sound between the first fastener 31 and the panel 325. Additionally, the patch 323 can be made of a material with good wear resistance to improve the wear resistance of the panel 325. Furthermore, considering insufficient light, the patch 323 can also be made of a fluorescent material to improve the visibility of the panel 325. Figure 5 As shown, in one embodiment, the panel 325 is further provided with a groove 124 for receiving a patch 323, the patch 323 being confined within the groove 124 to prevent displacement of the patch 323 on the housing 10. Figure 4 As shown, in one embodiment, the patch 323 is provided with at least one through hole 3231, which mates with the slot of the limiting groove 322 and / or the slot of the fastening groove 324.

[0060] Furthermore, when measuring the perimeter of the object 200, it is usually necessary to wrap the end of the measuring tape 20 around the object 200 and then bring it against the measuring tape 20. The perimeter of the object 200 can then be obtained by reading the scale value at the point of contact on the measuring tape 20. For example... Figure 13 , Figure 14 and Figure 17As shown, in order to bring the second end of the measuring tape 20 as close as possible to the opening 122 of the outer casing 10, in some embodiments, a tape opening 314 is provided at the connection between the first fastener 31 and the measuring tape 20. A chamfered platform 313 is provided at the end of the first fastener 31 near the tape opening 314, and the chamfered surface 3131 of the chamfered platform 313 is located on the side facing the panel 325. The tape opening 314 is located at the end of the chamfered surface 3131. Correspondingly, the panel 325 is provided with a beveled surface 3251, which is located on the side of the panel 325 near the opening 122. The inclination angle of the beveled surface 3251 is the same as the inclination angle of the chamfered surface 3131, and the opening 122 is located at the end of the beveled surface 3251. After the first fastener 31 is attached to the panel 325, the chamfered surface 3131 and the beveled surface 3251 are in contact with each other. At this time, the distance between the tape opening 314 and the opening 122 can be negligible. Alternatively, the measurement error can be limited to a smaller range through length compensation.

[0061] In conjunction with the above embodiments, at least one of the first sidewall 101 and the second sidewall 102 is provided with the aforementioned second fastener 32. Each second fastener 32 may also be provided with one or more of the aforementioned limiting groove 322, fastening groove 324, and patch 323. The opposite sides of the first fastener 31 are correspondingly provided with limiting blocks 311 and / or undercuts 312. For example, but not limited to, if both the first sidewall 101 and the second sidewall 102 are provided with second fasteners 32, and the panel 325 of one second fastener 32 is provided with a limiting groove 322 and the panel 325 of the other second fastener 32 is provided with a fastening groove 324, then the first side of the first fastener 31 is provided with a limiting block 311 and the second side is provided with an undercut 312. If the limiting groove 322 and the fastening groove 324 are provided on the same panel 325, then at least one side of the first fastener 31 is provided with an opposing limiting block 311 and an undercut 312. If the first sidewall 101 or the second sidewall 102 is provided with a second fastener 32, and the panel 325 of the second fastener 32 is provided with a limiting groove 322 or / and a buckle groove 324, then the first fastener 31 is provided with a limiting block 311 or / and a buckle 312 on the side corresponding to it.

Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
