Technical Field

[0001] The utility model relates to the technical field of tape measures, in particular to a tape measure with a ferrule on its core shaft. Background Art

[0002] The tape measure is a commonly used measuring tool in daily life. The one that people often see is the steel tape measure, which is commonly used in construction and decoration. It is also one of the essential tools in the household. It is divided into fiber tape measures, tape measures, waist rulers, etc. The tape measure can be rolled up because there is a spring inside the tape measure. When it is pulled out to measure the length, the length of the ruler and the spring is actually lengthened. Once the measurement is completed, the spring inside the tape measure will automatically shrink, and the ruler will also shrink under the action of the spring force, so the tape measure will roll up.

[0003] After searching, the announcement number CN208795089U, the name is a tape measure, including an outer bright tape, through research and analysis, it is found that although it is not easy to break during use, so the service life is long, but to a certain extent, there are still the following disadvantages;

[0004] For example, the core of a general tape measure rotates by the ribs inside the tape measure shell, which can easily lead to inadequate rib processing and imperfect product installation. The core will vibrate too much when rotating, making it uneven when pulled out and making a harsh sound, reducing the effectiveness of the tape measure. Therefore, it is necessary for us to design a tape measure with a ring on the core shaft to solve the above problem. Utility Model Content

[0023] See also Figure 3 The surfaces of the first scale shell 1 and the second scale shell 2 are movably connected with a brake plate 7, and the inner walls of the first scale shell 1 and the second scale shell 2 are fixedly connected with a convex plate 8, which is used in conjunction with the brake plate 7. By setting the brake plate 7 and the convex plate 8, the movable brake plate 7 can be used to tighten and lock the scale tape, which is convenient for positioning the scale tape.

[0024] See also Figure 2 A bottom brake 9 is installed through the bottom of the first scale shell 1 and the second scale shell 2, and the top of the bottom brake 9 penetrates into the inner cavity of the first scale shell 1 and the second scale shell 2. By setting the bottom brake 9, the bottom of the scale tape can be tightly locked, which is convenient for various locking and positioning of the scale tape.

[0025] See also Figure 5A spring 10 is fixedly connected to the left side of the first scale housing 1, and a side gate 11 is fixedly connected to the left side of the spring 10. The right side of the side gate 11 passes through the inner cavity of the first scale housing 1. The side gate 11 is connected by setting the spring 10 to facilitate the return of the side gate 11. By setting the side gate 11, the side of the scale core 3 can be locked. The side gate 11 is pushed up by a spring 10 to push up a side brake button to achieve the effect of never contacting the scale core 3. When the side brake is used normally, pressing the side gate 11 can lock the rotation of the scale core 3, which has the effect of braking the tape. Most of them do not have a spring 10 structure to push up the button, which will cause the side gate 11 to rub against the scale core 3 during actual use, causing noise and unsmooth use of the tape.

[0026] See also Figure 1 The surfaces of the first ruler shell 1 and the second ruler shell 2 are covered with a leather cover 12, and a trademark plate 13 is installed on the surface of the leather cover 12. By setting a snap connection between the trademark plate 13 and the leather cover 12, the leather cover 12 is connected to the first ruler shell 1, and the three can be flexibly disassembled to meet the needs of different groups of people, solving the problem that the trademark plate 13 of the measuring tape and the outer shell of the leather cover 12 cannot be flexibly disassembled at will.

[0027] See also Figure 1-Figure 3 A support mechanism 14 is installed on the front side of the first scale housing 1, and the support mechanism 14 includes a U-shaped plate 140. The rear side of the U-shaped plate 140 is fixedly connected to the first scale housing 1, and the front side of the U-shaped plate 140 contacts a frame 141. The top of the frame 141 is fixedly connected to a first L-shaped plate 142. The top of the front side of the frame 141 is connected to a first support roller 143 through a support block, and the bottom of the front side of the frame 141 is connected to a second support roller 144 through a support block. By setting the first support roller 143 and the second support roller 144, the ruler tape passes between the first support roller 143 and the second support roller 144, and contacts with them during the pulling process, which facilitates the smooth withdrawal of the ruler tape, avoids contact and friction between the ruler tape and the first scale housing 1 and the second scale housing 2, and extends the service life of the ruler tape.

[0028] See also Figure 3 The bottom of the frame 141 is movably connected with a bolt 145, and a connecting frame 146 is provided on the surface of the bolt 145 through a threaded sleeve. The top of the connecting frame 146 is connected to the second support roller 144 through a support block, and the rear side of the connecting frame 146 is fixedly connected with a second L-shaped plate 147. By arranging the bolt 145, the second L-shaped plate 147 and the connecting frame 146, the second support roller 144 can be adjusted to move vertically, and the distance between the first support roller 143 and the second support roller 144 can be adjusted to facilitate the support and transmission of tapes of different thicknesses. At the same time, the second L-shaped plate 147 can be adjusted to move vertically and separate from the U-shaped plate 140, which is convenient for separating and disassembling the frame 141 and the U-shaped plate 140.

[0029] When in use, the ferrule 6 supports the aluminum-zinc shaft 5 and one side of the ruler core 3, so that the ruler core 3 rotates stably, with low noise, smooth rotation, and smooth tape recovery. By pushing the brake plate 7, the movement of one side of the brake plate 7 will push the ruler tape to between the two convex plates 8 to lock the ruler tape, press the bottom brake 9 to lock the bottom of the ruler tape, and press the side brake 11 to contact the ruler core 3 to lock the ruler core 3;

[0030] Rotating the bolt 145 drives the connecting frame 146 to move vertically, and the connecting frame 146 drives the second support roller 144 to move vertically, and adjusts the distance between the first support roller 143 and the second support roller 144 to support the tape, thereby preventing the tape from contacting and rubbing with the first scale shell 1 and the second scale shell 2. Reversely rotating the bolt 145 drives the connecting frame 146 to move vertically, and the connecting frame 146 drives the second L-shaped plate 147 to move, so that it is separated from the U-shaped plate 140, and then the frame 141 is separated and disassembled from the U-shaped plate 140.
