Description

Technical Field

[0001] The invention belongs to the technical field of measuring tapes, in particular to a measuring tape. Background Art

[0002] Currently, the tape measure, also known as Lu Ban ruler, is a soft measuring tool made of plastic, steel bars, cloth and other materials. It is easy to carry and can measure the length of some curves. The clothing ruler used in the clothing industry is a tape measure, also known as a soft ruler. The materials used are PVC plastic and glass fiber.

[0003] The tape measuring tools currently used by people can be basically divided into two categories. The first category uses a positive compression spring to brake by the friction between the button and the ruler core, and the second category uses a side pressure torsion spring to brake by the friction between the button and the ruler tape. Secondly, the tape measuring tools used basically use the hook at the head of the tape as the detection reference, and the area covered by the ruler tape as the detection range. However, when we need to detect certain internal features, the ruler tape cannot completely cover the detection range due to the existence of the ruler shell space, so we can only roughly estimate the size of the range not covered by the ruler tape. Summary of the invention

[0004] The purpose of the present invention is to innovate the traditional tape measure braking method through a braking mechanism, a function button and a control button, thereby realizing a tape measure braking structure with a small structural space, good braking effect and simple assembly. At the same time, the surveying result of the first object is used as a reference to reset to zero, and then the second object is surveyed. The result obtained in this way is the size difference between the two detected objects.

[0005] The technical solution adopted by the present invention is as follows: a tape measure, comprising:

[0006] An installation shell, the installation shell encloses a receiving cavity, and the installation shell is also provided with an inlet and outlet communicating with the receiving cavity;

[0007] A rotating mechanism, accommodated in the accommodating cavity and rotatably connected to the mounting housing;

[0010] When the brake button is not operated, the extrusion spring remains in a compressed state, so that the measuring mechanism is fixed by the brake slide and the mounting housing and braked;

[0011] When the brake button is operated, the brake button pushes the brake slide to move so that the size of the first gap increases, and the measuring mechanism is not fixed and the brake is released.

[0012] Among them, the rotating mechanism includes a fixed block, a connecting rod and a rotating ring, the outer wall of the fixed block is movably arranged on the mounting shell, one end of the connecting rod is fixed on the fixed block, and two rotating rings are provided, and both rotating rings are movably arranged on the connecting rod.

[0013] Among them, the rotating mechanism also includes a rotating sleeve, a closing plate and a revolving strip. The rotating sleeve and the closing plate are fixed to each other, and the rotating sleeve and the closing plate are movably connected to the connecting rod through two rotating rings respectively, and the revolving strip is arranged inside the rotating sleeve.

[0014] Wherein, the measuring mechanism comprises a measuring tape, the measuring tape is wound around a rotating sleeve, and the measuring tape extends from or retracts into the accommodating cavity through an inlet and outlet, and the measuring tape passes through the first gap.

[0015] Wherein, the braking mechanism further comprises an auxiliary rod and an auxiliary rotating shaft, and the auxiliary rotating shaft is movably connected to the mounting shell through the auxiliary rod.

[0021] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0022] (1) In the present invention, the two types of braking methods have their own defects in service life, structural space and assembly efficiency. Through the use of a spring bin structure, an innovation is made to the traditional tape measure braking method, and a tape measure braking structure with a small structural space, good braking effect and easy assembly is invented.

[0023] (2) In the present invention, a ruler case reference button is added on the opposite side of the ruler tape outlet of the ruler case through the innovative design of the ruler case.

It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0038] Embodiment 1, refer to Figure 1-Figure 11 :A tape measure, comprising:

[0039] The installation shell 1 encloses a receiving cavity, and the installation shell 1 is also provided with an inlet and outlet communicating with the receiving cavity;

[0040] A rotating mechanism is accommodated in the accommodating cavity and is rotatably connected to the mounting housing 1;

[0041] a measuring mechanism, the measuring mechanism being arranged on the rotating mechanism; and

[0042] The brake mechanism comprises a brake button 2, a fixing frame 3, an extrusion spring 4 and a brake slide 5. The brake slide 5 is accommodated in the accommodating chamber and movably connected to the mounting housing 1. There is a first gap between the brake slide 5 and the mounting housing 1. The brake button 2 is movably connected to the mounting housing 1 through the fixing frame 3 and extends from the accommodating chamber to the outside of the brake slide 5. The two ends of the extrusion spring 4 are respectively abutted against the brake slide 5 and the mounting housing 1; wherein:

[0043] When the brake button 2 is not operated, the compression spring 4 remains in a compressed state, so that the measuring mechanism is fixed by the brake slide 5 and the mounting housing 1 and braked;

[0044] When the brake button 2 is operated, the brake button 2 pushes the brake slide 5 to move so that the size of the first gap increases, and the measuring mechanism is not fixed and the brake is released;

[0045] The measuring mechanism includes a measuring tape 12, which is wound around the rotating sleeve 9 and extends from or retracts into the accommodating cavity through the inlet and outlet. The measuring tape 12 passes through the first gap. The braking mechanism also includes an auxiliary rod 13 and an auxiliary rotating shaft 14. The auxiliary rotating shaft 14 is movably connected to the mounting shell 1 through the auxiliary rod 13.

[0046] The measuring tape mechanism can be pulled by the rotating mechanism, and the measuring tape mechanism is automatically retracted at the same time. The distance can be measured by the measuring tape mechanism. The measuring tape mechanism can be restricted by the braking mechanism. When the measuring tape mechanism is pulled, the measuring tape mechanism can be fixed by the braking mechanism to facilitate measurement. The braking button 2 can be pressed to move the braking slide 5 upward so that the measuring tape 12 can be retracted under the action of the rewinding strip 11. The auxiliary shaft 14 can be rotated by the auxiliary rod 13 to assist in pulling and retracting the measuring tape 12. When the braking button 2 is not operated, the extrusion spring 4 remains in a compressed state so that the measuring mechanism is fixed by the braking slide 5 and the mounting housing 1 and braked. When the braking button 2 is operated, the braking button 2 pushes the braking slide 5 to move so that the size of the first gap increases, and the measuring mechanism is not fixed and the brake is released.

[0047] Example 2, refer to Figure 1-Figure 11 The rotating mechanism includes a fixed block 6, a connecting rod 7 and a rotating ring 8. The outer wall of the fixed block 6 is movably arranged on the mounting shell 1. One end of the connecting rod 7 is fixed to the fixed block 6. Two rotating rings 8 are provided. Both rotating rings 8 are movably arranged on the connecting rod 7. The rotating mechanism also includes a rotating sleeve 9, a closing plate 10 and a revolving strip 11. The rotating sleeve 9 and the closing plate 10 are fixed to each other, and the rotating sleeve 9 and the closing plate 10 are movably connected to the connecting rod 7 through two rotating rings 8 respectively. The revolving strip 11 is arranged inside the rotating sleeve 9.

[0048] Through the fixing block 6, the fixing block 6 plays a fixing role, so that the connecting rod 7 cannot rotate. Through the rotating ring 8, the rotating sleeve 9 and the closing plate 10 can be rotated. Through the rewinding strip 11, when the rotating sleeve 9 rotates, it will drive the rewinding strip 11 to tighten, loosen the rotating sleeve 9, and the rewinding strip 11 will automatically retract under the action of elastic force.

[0049] Example 3, refer to Figure 1-Figure 11 A display mechanism is installed on the top of the mounting shell 1, and the display mechanism includes a protective outer frame 15 and a fixing plate 16, and the protective outer frame 15 and the fixing plate 16 are fixed on the mounting shell 1. The display mechanism also includes a display board 17 and a display screen 18, and the display board 17 is fixed on the fixing plate 16, and the outer wall of the display screen 18 is arranged on the inner surface of the protective outer frame 15. A control board 19 is installed inside the mounting shell 1, and two function buttons 20 and three control buttons 22 are slidingly provided on the right surface of the outer wall of the mounting shell 1, a charging port is installed on the rear surface of the outer wall of the mounting shell 1, and a battery life battery 21 is arranged inside the mounting shell 1.

[0050] The control board 19 can control the circuit, and the control board 19 is provided with a button drive. The drive of the board 19 can be controlled by pressing two function buttons 20 and three control buttons 22. One of the two function buttons 20 is a memory button, which can record the last data, and the other is a reset button, which can reset the data. The surveying result of the first object is used as a reference to clear the data, and then the second object is surveyed. The result obtained in this way is the size of the two detected objects. The three control buttons 22 can be used to set and operate the measuring tape. The measuring tape can be charged through the charging port. The display board 17 and the display screen 18 can be protected by the protective frame 15. The display mechanism can be fixed by the fixing plate 16. The protective frame 15 controls the display screen 18 so that the display screen 18 displays the pulling distance value. The brake slide 5 is squeezed on the measuring tape 12 under the action of the squeezing spring 4 to prevent the measuring tape 12 from moving.

[0051] When in use, the rotating mechanism can pull the measuring tape mechanism, and the measuring tape mechanism is automatically retracted. The distance can be measured by the measuring tape mechanism. The braking mechanism can limit the measuring tape mechanism. When the measuring tape mechanism is pulled, the measuring tape mechanism can be fixed by the braking mechanism to facilitate measurement. The braking button 2 can be pressed to make the braking slide 5 move upward, so that the measuring tape 12 is retracted under the action of the rewinding strip 11. The auxiliary rod 13 allows the auxiliary rotating shaft 14 to rotate, thereby assisting the pulling and retraction of the measuring tape 12. When the braking button 2 is not operated, the extrusion spring 4 remains in a compressed state, so that the measuring mechanism is fixed by the braking slide 5 and the mounting housing 1 and braked. When the braking button 2 is operated, the braking button 2 pushes the braking slide 5 to move, so that the size of the first gap increases, and the measuring mechanism is not fixed and the brake is released. The fixing block 6 plays a fixing role, so that the connecting rod 7 cannot rotate. The rotating ring 8 can make the rotating sleeve 9 and the closing plate 10 rotate. When the rotating sleeve 9 rotates, it will drive the rewinding strip 11. Tighten and loosen the rotating sleeve 9, and the rewinding strip 11 is automatically retracted under the action of elastic force. The control board 19 can control the circuit. At the same time, the control board 19 is provided with a button drive. Pressing two function buttons 20 and three control buttons 22 can control the drive of the board 19. One of the two function buttons 20 is a memory button, which can record the last data, and the other is a reset button, which can reset the data. The surveying result of the first object is used as a reference to clear the data, and then the second object is surveyed. The result obtained is the size of the two detected objects. The three control buttons 22 can be used to set and operate the measuring tape. The charging port can charge the measuring tape. The protective frame 15 can protect the display board 17 and the display screen 18. The fixing plate 16 can fix the display mechanism. The protective frame 15 controls the display screen 18 so that the display screen 18 displays the pulling distance value. The brake slide 5 is squeezed on the measuring tape 12 under the action of the squeezing spring 4 to prevent the measuring tape 12 from moving.
