Description

Technical Field

[0001] This utility model relates to the field of electronic distance measuring tape technology, and more specifically to an electronic distance measuring tape that can be automatically calibrated. Background Technology

[0002] Electronic distance measuring tapes are tools that use laser, ultrasonic, or infrared technology for non-contact distance measurement. Compared with traditional tape measures, they have advantages such as high precision, long-distance measurement, and data storage. Laser or ultrasonic distance measuring instruments, through built-in sensors and intelligent algorithms, can correct measurement errors in real time to ensure accurate and reliable data.

[0003] However, existing automatically calibrated electronic distance measuring tapes require multi-directional distance measurement in actual use. When the distance measuring tape is turned, it needs to be manually rotated, which is cumbersome and causes wear on the bottom of the tape during rotation, thus reducing its service life. In addition, when measuring distances at a certain height, the distance measuring tape needs to be manually placed at a high position, which may cause it to fall and be damaged, posing a certain safety hazard. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides an automatically calibrated electronic distance measuring tape to solve the problems existing in the background art.

[0005] This utility model provides the following technical solution: an automatically calibrated electronic distance measuring tape, comprising a distance measuring tape body, characterized in that: auxiliary limiting rods are fixedly connected to both sides of the bottom of the distance measuring tape body; a lifting component is fixedly connected to the bottom of the distance measuring tape body and to the middle of the side adjacent to the auxiliary limiting rods; a steering wheel is fixedly connected to the end of the auxiliary limiting rods away from the distance measuring tape body; a support base is movably sleeved on the surface of the steering wheel; a protective shell is fixedly connected to one side of the surface of the support base; a meshing gear is movably sleeved inside the protective shell; a servo motor is fixedly connected to the bottom of the protective shell; and the meshing gear is driven by the servo motor. This utility model, by providing a meshing gear, a servo motor, a steering wheel, and a transmission gear, facilitates the rotation of the meshing gear via the servo motor when the distance measuring tape body is in use and needs to be turned, thereby causing the steering wheel to move the distance measuring tape body to different directions for distance measurement operations, avoiding wear on the bottom of the distance measuring tape body, and thus increasing the service life of the distance measuring tape body.

[0006] Furthermore, a circular hole is provided at the top of the support base, a rotating groove is provided at the position where the steering wheel is movably connected to the support base, a motor mounting groove is provided at the bottom of the support base, and a gear groove is provided inside the protective shell.

[0007] Furthermore, a transmission gear is fixedly sleeved on the surface of the steering wheel, and the transmission gear meshes with a meshing gear inside the protective shell.

[0008] Furthermore, the auxiliary limiting rod includes a limiting tube, and a telescopic rod is movably sleeved inside the limiting tube. The top end of the telescopic rod is fixedly connected to the bottom of the measuring tape body.

[0009] Furthermore, the lifting component includes a threaded pipe, a drive motor is fixedly connected to the bottom of the threaded pipe, a telescopic screw is movably sleeved inside the threaded pipe, and the top of the telescopic screw is fixedly connected to the bottom of the measuring tape body.

[0010] The technical effects and advantages of this utility model are as follows:

[0011] 1. This utility model, by incorporating meshing gears, a servo motor, a steering wheel, and a transmission gear, facilitates the use of the distance measuring tape body when it needs to be turned. The servo motor drives the meshing gear to rotate, which in turn drives the transmission gear to rotate. This allows the steering wheel to move the top of the distance measuring tape body to different directions for distance measurement operations, preventing wear on the bottom of the distance measuring tape body and thus increasing its service life.

[0012] 2. This utility model, by incorporating a drive motor, a lifting component, and an auxiliary limiting rod, facilitates the use of the distance measuring tape body at a certain height for distance measurement. The drive motor drives the lifting component to rise, and the auxiliary limiting rod further restricts the rise of the distance measuring tape body, thereby ensuring a stable rise for distance measurement operations and preventing the safety hazard of the distance measuring tape body falling from a high position.

[0018] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The automatically calibrated electronic distance measuring tape involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0019] Reference Figure 1 - Figure 4 As shown, this utility model provides an automatically calibrated electronic distance measuring tape, including a distance measuring tape body 1. The feature is that: auxiliary limiting rods 2 are fixedly connected to both sides of the bottom of the distance measuring tape body 1; a lifting component 3 is fixedly connected to the bottom of the distance measuring tape body 1 and at the middle of the side adjacent to the auxiliary limiting rods 2; a steering wheel 4 is fixedly connected to the end of the auxiliary limiting rods 2 away from the distance measuring tape body 1; a support base 5 is movably sleeved on the surface of the steering wheel 4; a protective shell 6 is fixedly connected to one side of the surface of the support base 5; and a meshing gear 7 is movably sleeved inside the protective shell 6. A servo motor 8 is fixedly connected to the bottom of the protective shell 6, and a meshing gear 7 is connected to the servo motor 8. This utility model, by providing a meshing gear 7, a servo motor 8, a steering wheel 4, and a transmission gear 401, is beneficial when the measuring tape body 1 is in use and needs to be turned. The servo motor 8 drives the meshing gear 7 to rotate, and the meshing gear 7 drives the transmission gear 401 to rotate. This allows the steering wheel 4 to drive the measuring tape body 1 on top to different directions for distance measurement operations, avoiding wear on the bottom of the measuring tape body 1 and thus increasing the service life of the measuring tape body 1.

[0020] The support base 5 has a circular hole 501 at the top, a rotating groove 502 at the position where it is connected to the steering wheel 4, a motor mounting groove 503 at the bottom, and a gear groove 601 inside the protective shell 6.

[0021] Among them, a transmission gear 401 is fixedly sleeved on the surface of the steering wheel 4, and the transmission gear 401 meshes with the meshing gear 7 inside the protective shell 6.

[0022] The auxiliary limiting rod 2 includes a limiting tube 201, and a telescopic rod 202 is movably sleeved inside the limiting tube 201. The top end of the telescopic rod 202 is fixedly connected to the bottom of the measuring tape body 1.

[0023] The lifting component 3 includes a threaded pipe 301, a drive motor 9 is fixedly connected to the bottom of the threaded pipe 301, a telescopic screw 302 is movably sleeved inside the threaded pipe 301, and the top of the telescopic screw 302 is fixedly connected to the bottom of the measuring tape body 1.

[0024] The working principle of this utility model is as follows: First, when in use, the servo motor 8 is turned on, causing the servo motor 8 to drive the meshing gear 7 inside the gear groove 601 of the protective shell 6 to rotate. Then, the rotation of the meshing gear 7 drives the transmission gear 401 on the surface of the steering wheel 4 to rotate. Then, the transmission gear 401 drives the steering wheel 4 and the auxiliary limiting rod 2 to rotate. Then, the auxiliary limiting rod 2 is driven by the steering wheel 4 to rotate the measuring tape body 1 in different directions. Then, when it is necessary to raise the measuring tape body 1, the transmission motor 9 inside the motor mounting groove 503 is turned on, causing the transmission motor 9 to drive the threaded pipe 301 to rotate inside the steering wheel 4. Then, the rotation of the threaded pipe 301 causes the telescopic screw 302 at the bottom of the measuring tape body 1 to rise under the restriction of the auxiliary limiting rod 2. At this time, the measuring tape body 1 drives the telescopic rod 202 to rise inside the limiting tube 201, thus completing the raising of the measuring tape body 1.

[0025] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
