Description

Technical Field

[0001] This utility model relates to the field of measuring tools, and in particular to a measuring tape for engineering acceptance. Background Technology

[0002] During project acceptance, it is necessary to measure some important dimensions of the project. Currently, infrared measurement is often used, but it is difficult to use infrared measurement in areas without reference points, so traditional measuring tapes are still required.

[0003] However, due to the long measurement distance, the measuring tape is quite long, making the winding process cumbersome. Repeated use reduces winding efficiency, affecting measurement efficiency, and also increases the operator's workload. Therefore, it is necessary to design a measuring tape that can automatically unwind and rewind, and operate stably and reliably. Utility Model Content

[0004] To address the aforementioned technical deficiencies, this utility model provides a measuring tape for engineering acceptance, which can automatically rewind and unwind, and operates stably and reliably.

[0005] This utility model discloses a measuring tape for engineering acceptance, including a winding shaft and a tape measure body wound on the winding shaft, and a base. Upward-extending vertical plates are provided on both sides of the base. The winding shaft is rotatably disposed between the vertical plates. A connecting beam is provided at the top of the vertical plates. Baffles are provided at both ends of the winding shaft between the vertical plates. The tape measure body is wound on the winding shaft between the baffles. A toothed ring is provided around the periphery of one of the baffles. The base has a hollow structure. A hollow area is provided on the base directly below the toothed ring. A motor is provided inside the base. A drive gear is provided on the output shaft of the motor. The drive gear is located within the hollow area and meshes with the toothed ring at the hollow area. A battery and a controller are also provided inside the base. A control switch is provided on the controller and extends to the outside of the base. The battery is connected to the motor through the controller.

[0006] A pivot is provided between the uprights on one side, and a guide pipe is provided on the pivot. The guide pipe extends above the winding shaft, and the measuring tape body passes through the guide pipe and extends to the outside.

[0007] The guide pipe has a rectangular cross-section channel inside for the measuring tape body to pass through; the end of the guide pipe near the winding shaft is bent downwards into an arc shape.

[0008] A support guide roller is provided below the guide pipe near one end of the winding shaft. The two ends of the support guide roller are set on the lower surface of the guide pipe through support seats, and the support guide roller is rotatably connected to the support seats.

[0009] A guide roller is provided on the guide pipe near one end of the winding shaft. The two ends of the guide roller are rotatably mounted on the side walls at both ends of the guide pipe. The highest point of the guide roller is flush with or higher than the bottom surface of the channel inside the guide pipe.

[0010] The measuring tape for engineering acceptance obtained by this utility model uses a motor to drive the baffle and the winding shaft to rotate, thereby realizing the automatic winding and unwinding of the measuring tape body, which can improve measurement efficiency and reduce labor intensity.

[0017] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0018] Example 1:

[0019] like Figures 1-6As shown, this utility model discloses a measuring tape for engineering acceptance, including a winding shaft 5 and a measuring tape body 3 wound on the winding shaft 5, and a base 1. Upwardly extending vertical plates 2 are provided on both sides of the base 1. The winding shaft 5 is rotatably disposed between the vertical plates 2. A connecting beam 6 is provided at the top of the vertical plates 2. Baffles 7 are provided at both ends of the winding shaft 5 between the vertical plates 2. The measuring tape body 3 is wound on the winding shaft 5 between the baffles 7. A toothed ring 8 is provided around one of the baffles 7. The base 1 has a hollow interior. The structure includes a hollow area on the base 1 directly below the gear ring 8. A motor 11 is installed inside the base 1, and a drive gear 12 is installed on the output shaft of the motor 11. The drive gear 12 is located in the hollow area and meshes with the gear ring 8 in the hollow area. A battery 15 and a controller 13 are also installed inside the base 1. A control switch 14 is installed on the controller 13 and extends to the outside of the base 1. The battery 15 is connected to the motor 11 through the controller 13.

[0020] Two upright plates 2 are mounted on the base 1 for mounting the winding shaft 5. The winding shaft 5 is rotatably connected to the upright plates 2, and the rotation of the winding shaft 5 enables the winding and unwinding of the measuring tape body 3. Two baffles 7 are mounted on the winding shaft 5. The baffles 7 are preferably circular, and the measuring tape body 3 is wound on the winding shaft 5 between the baffles 7. The distance between the baffles 7 is exactly the same as the width of the measuring tape body 3 to ensure stable winding of the measuring tape body 3. A motor 11 is installed inside the base 1, and the motor 11 drives the drive gear 12 to rotate. A gear ring 8 is mounted on one of the baffles 7, and the drive gear 12 meshes with the gear ring 8, so the motor 11 can drive the baffle 7 to rotate. The baffle 7 is fixed to the winding shaft 5, so the motor 11 can ultimately drive the winding shaft 5 to rotate, realizing the winding and unwinding of the measuring tape body 3. A battery 15 inside the base 1 provides power to the motor 11, and a controller 13 is used to control the operation of the motor 11. The control switches 14 on the controller 13 extend to the outside of the base 1. There are two control switches 14; pressing one will cause the motor 11 to rotate forward, and pressing the other will cause the motor 11 to rotate in reverse. This control method is a conventional method and will not be described in detail here. Therefore, one control switch 14 can drive the tape measure body 3 to unwind, and the other control switch 14 can drive the tape measure body 3 to rewind.

[0021] In normal operation, the measuring tape described in this embodiment also requires two people to work together. One person pulls the end of the measuring tape body 3, while the other person holds the base 1 and presses the control switch 14 to unwind the measuring tape body 3. At this time, the measuring tape body 3 unwinds, and one person pulls the end of the measuring tape body 3 forward to measure the target object. After the measurement is completed, the person holding the base 1 presses another control switch 14, and the winding shaft 5 winds up the measuring tape body 3. The person holding the end of the measuring tape body 3 then slowly returns the measuring tape body 3 to its original position.

[0022] In this process, there is no need to manually crank the measuring tape to retract the tape measure body 3. The operation is simple and convenient, with low labor intensity, making it suitable for centralized measurement situations such as project acceptance. The operator's arms will not feel sore.

[0023] A handle 4 is provided at the top of the connecting beam 6 for easy carrying.

[0024] A rotating shaft 9 is provided between the upright plates 2 on one side, and a guide pipe 10 is provided on the rotating shaft 9. The guide pipe 10 extends above the winding shaft 5, and the measuring tape body 3 passes through the guide pipe 10 and extends to the outside. The setting of the guide pipe 10 makes the input and output of the measuring tape body 3 more stable during the winding and unwinding process, and it is less likely to cause problems such as tangling, thus ensuring high reliability.

[0025] The guide pipe 10 has a rectangular cross-section channel inside for the measuring tape body 3 to pass through; the end of the guide pipe 10 near the winding shaft 5 is bent downwards into an arc shape. The rectangular cross-section channel has a width that is the same as or slightly larger than the measuring tape body 3, and its height can be slightly larger than the measuring tape body 3, to ensure that the measuring tape body 3 can pass through smoothly and will not fold over, thus ensuring high winding reliability.

[0026] A support guide roller 16 is provided below the guide pipe 10 near one end of the winding shaft 5. The two ends of the support guide roller 16 are mounted on the lower surface of the guide pipe 10 via support seats, and the support guide roller 16 is rotatably connected to the support seats. The support guide roller 16 abuts against the winding roller or the measuring tape body 3 on the winding roller, so that the guide pipe 10 can rotate around the rotating shaft 9 during the winding process to adjust the guiding position. It will not interfere with the measuring tape body 3 on the winding shaft 5, and at the same time, it can also press the measuring tape body 3 on the winding shaft 5 tightly during the winding process to maintain tight winding.

[0027] A guide roller 17 is provided on the guide pipe 10 near one end of the winding shaft 5. The two ends of the guide roller 17 are rotatably mounted on the side walls at both ends of the guide pipe 10. The highest point of the guide roller 17 is flush with or higher than the bottom surface of the channel inside the guide pipe 10.

[0028] When the measuring tape body 3 is output from the guide pipe 10, it passes around the guide roller 17 and is then wound onto the winding roller. This prevents the measuring tape body 3 from wearing against the end of the guide pipe 10 due to the conveying angle, thus extending the service life of the measuring tape body 3. The guide roller 17 can be located inside or outside the end of the guide pipe 10, depending on the actual requirements.
