Description

Technical Field

[0001] The utility model relates to the technical field of measuring rulers, in particular to a waist measuring ruler. Background Art

[0002] In order to know the waist circumference, arm and leg thickness in time, a soft tape measure is usually used. The front end of the soft tape measure has a cylindrical tape measure head. At the same time, a positioning hole is provided on one side of the tape measure body. When a certain part needs to be measured, the tape measure body is held in one hand and the tape measure head is pinched with the other hand to pull out the soft tape measure and wrap it around the part to be measured (such as the leg, arm or waist), and then the tape measure head is inserted into the positioning hole. This makes it convenient for the measurer to free up his hands to turn the soft tape measure to observe the measured value.

[0003] Although the above structure is convenient for users to measure by themselves, it has the following disadvantages: when the tape measure head is inserted into the positioning hole, when the user is browsing the measurement data, if the user is not careful, the tape measure head will automatically slip out of the positioning hole.

Therefore, the terms describing the positional relationship in the drawings are only used for illustrative purposes and cannot be understood as a limitation on the present utility model. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to specific circumstances.

[0025] Reference Figure 1-4 As shown, it is a preferred embodiment provided by the utility model.

[0026] The waist measuring tape comprises a main body 10 and a measuring tape 40. The inner end of the measuring tape 40 is rolled up inside the main body 10. The outer end of the measuring tape 40 is connected to a magnetic head 20, which is exposed outside the main body 10. The main body 10 is provided with a magnet buckle 30. The outer surface of the measuring tape 40 is evenly provided with scale marks and scale numbers along the length direction.

[0027] When measuring waist circumference, the magnetic head 20 is pulled out of the main body 10 so that the measuring tape 40 is wrapped around the part to be measured until the magnetic head 20 abuts against the magnetic buckle 30. The magnetic head 20 is attracted by the magnetism of the magnetic buckle 30, and the measuring tape 40 and the main body 10 are wrapped around to form a measuring ring 60 for measuring the part to be measured.

[0028] The waist circumference ruler provided above has a main body 10 that can be used to magnetically absorb the magnetic head 20 through the magnet buckle 30, so that when the magnetic head 20 is pulled away from the main body 10, the magnetic head 20 will drive the measuring tape 40 to be pulled away from the main body 10, so that the measuring tape 40 can measure around the measured part, and the magnetic head 20 is attracted by the magnetism of the magnet buckle 30. In this way, the user does not need to worry about whether the magnetic head 20 will be separated from the magnet buckle 30 when looking through the measurement data. It is easy to use and has a simple structure.

[0029] The magnet buckle 30 and the magnetic head 20 are respectively located on both sides of the main body 10. In this way, it is convenient for measurement and use.

[0030] A positioning groove 11 is recessed inwardly on one side of the main body 10, and the magnet buckle 30 is located in the positioning groove 11. In this way, the main body 10 can limit the position where the magnetic suction head 20 is adsorbed by the magnet buckle 30 through the positioning groove 11, preventing the magnetic suction head 20 from shaking randomly during the measurement process.

[0031] A drawing slot 12 for the tape measure 40 to be extended and pulled is provided on the other side of the main body 10, and the drawing slot 12 is communicated with the interior of the main body 10. In this way, the tape measure 40 can be extended and pulled easily.

[0032] The inner end of the magnetic head 20 abuts against the drawer slot 12, and the outer end of the magnetic head 20 is exposed outside the drawer slot 12. In this way, the magnetic head 20 can block the inside of the main body 10 to prevent dust from entering the inside of the main body 10 from the drawer slot 12, thereby playing a role of dust and moisture prevention.

[0033] An enclosed end face 13 is arranged between the positioning groove 11 and the drawing groove 12 and is located outside the main body 10. The measuring tape 40 and the enclosed end face 13 are surrounded to form a measuring ring 60. In this way, the measuring closure function of the main body 10 and the measuring tape 40 is facilitated.

[0034] The main body 10 is provided with a rotating ring 14, the inner end of the measuring tape 40 is connected to the rotating ring 14, and the rotating ring 14 is provided with a spring coil 15 for driving the rotating ring 14 to rotate and retract the measuring tape 40. In this way, the main body 10 can be connected with the measuring tape 40 through the rotating ring 14, and the rotating ring 14 can automatically retract the measuring tape 40 into the main body 10 by using the elastic force of the spring coil 15, so that the measuring tape 40 can be recycled and used conveniently.

[0035] The magnetic attraction of the magnet buckle 30 is greater than the elastic force of the spring coil 15. In this way, the redundant measuring tape 40 can be retracted into the main body 10 by the elastic force of the spring coil 15, making it more convenient and accurate for the user to measure.

[0036] In this embodiment, a reeling button 50 for controlling the elastic reeling of the spring coil 15 is disposed on the main body 10 . The reeling button 50 cooperates with the rotating ring 14 , and the top of the reeling button 50 is exposed outside the main body 10 .

[0037] When measurement is required, the magnetic head 20 drives the measuring tape 40 to be pulled out of the main body 10. In the process of pulling out the measuring tape 40, the rotating ring 14 will rotate accordingly. However, after the rotating ring 14 is restricted by the rewinding button 50, the rotating ring 14 can only rotate in one direction, so as to prevent the measuring tape 40 from being randomly retracted into the main body 10 due to the influence of the spring coil 15.

[0038] When the measurement is completed and the measuring tape 40 needs to be retracted into the main body 10, it is only necessary to separate the magnetic head 20 from the magnet buckle 30, and then drive the winding button 50 to separate from the rotating ring 14, so that the spring roll 15 drives the rotating ring 14 to elastically rewind, and the measuring tape 40 can be automatically retracted into the main body 10, which is very convenient.

[0039] In this embodiment, the bottom of the winding button 50 is inserted into the interior of the rotating ring 14 from top to bottom, and a spring column 16 is provided in the main body 10. The bottom of the spring column 16 abuts against the interior of the main body 10, and the top of the spring column 16 abuts against the bottom of the winding button 50. In this way, the winding button 50 can be driven by the spring column 16 to reset.

[0040] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
