DETAILED DESCRIPTION

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] The preferred embodiment of the present invention will be described below.

[0024] Example 1

[0025] like Figures 1-3 As shown, Embodiment 1 of this utility model provides a waist and abdominal circumference measuring tape, including a housing 1, a top cover 2 fixedly mounted on the top of the housing 1, and a top cover 3 mounted on the inner side of the top of the top cover 2. A rotating shaft 4 is rotatably mounted in the center of the housing 1 through a bearing 5. The bearing 5 provides smooth rotational support for the rotating shaft 4, reducing friction and wear. At the same time, a measuring tape chuck 7 is fixedly connected to the rotating shaft 4 through an external shaft retainer 6. The shaft retainer 6 firmly fixes the measuring tape chuck 7 to the rotating shaft 4, ensuring synchronous rotation between the two. A measuring tape strip 8 is fastened to the measuring tape chuck 7, and one end of the measuring tape strip 8 extends to the outside of the housing 1 for measurement. A dial 19 is provided inside the top cover 2, and the top of the rotating shaft 4 is connected through to a pointer 20 on the upper surface of the dial 19. The pointer 20 reflects the length of the stretched measuring tape strip 8, thereby indicating the measured waist or abdominal circumference.

[0026] The outer side of the top cover 2 is provided with a round button 15, a sensor 16, an LED indicator 17, and a long button 18. The round button 15 and the long button 18 are used to control the measurement process, reset the measurement value, or perform other operations. The sensor 16 is used to detect the stretching state of the measuring tape strip 8 in order to trigger the corresponding measurement or indication function. The LED indicator 17 displays the user's chest circumference level by displaying different colored lights, providing the user with intuitive feedback.

[0027] In use, the user pulls the hook 11 on the measuring tape strip 8 to measure around the body part. The stretching of the measuring tape strip 8 causes the measuring tape chuck 7 and the rotating shaft 4 to rotate synchronously. The rotation of the rotating shaft 4 further drives the pointer 20 on the dial 19 to move, displaying the measurement result. The user can understand the specific value of the waist or abdominal circumference based on the reading on the dial 19 (see details). Figure 4 and Figure 5 During the measurement process, the user can press the brake button 12 at any time to lock the position of the measuring tape strip 8 to prevent it from retracting accidentally. After the measurement is completed, the brake button 12 is released, and the measuring tape spring coil 13 will automatically retract the measuring tape strip 8 into the cover 1. The user can also sense the number of rotations of the pointer 20 in real time through components such as the round button 15, sensor 16 and LED indicator 17.

[0028] At the same time, the LED indicator 17 can cooperate with the inductor 16 to display the chest circumference level, and the different colors can be distinguished, so that the user can understand the chest circumference condition at a glance.

[0029] Further, the tape reel 7 is installed outside the rotating shaft 4 and rotates synchronously with the rotating shaft 4, so that the stretching or retraction of the tape 8 can drive the rotating shaft 4 to rotate.

[0030] Further, the top cover 3 is made of polycarbonate, which is a plastic with high strength, high transparency and impact resistance.

[0031] Further, the limit ring 9 is arranged inside the shell 1 and located on the path of the tape 8, and the limit ring 9 is used to limit the extension length of the tape 8 to prevent it from being damaged by overstretching.

[0032] Further, the bottom end of the shell 1 is provided with a base 10, and the tape spring reel 13 is fixedly arranged on the base 10, and the other side of the tape spring reel 13 is connected with the tape 8, one end of the tape spring reel 13 is fixed on the base 10, and the other end is connected with the tape 8.

[0033] Further, the tape 8 extends to the outside of the shell 1 and is provided with a tape hook 11 at one end, the tape hook 11 is used to hook the measurement part, the outside of the shell 1 is provided with a brake button 12, and the brake button 12 is abutted to the tape reel 7 on the side close to the inside of the shell 1, the outside of the shell 1 is fixedly sleeved with a pull rope 14, and the brake button 12 contains a connecting rod and a spring transmission mechanism, which can respond to the pressing action of the button and transmit the action to the rotating shaft 4 or the tape reel 7 inside the shell 1.

[0034] The above technical scheme can be analyzed: when the button is pressed, the transmission mechanism will prevent the further rotation of the rotating shaft 4, so as to lock the tape 8 and keep it at the current position, and when the button is released, the transmission mechanism allows the rotating shaft 4 to continue to rotate, and the tape 8 can be retracted or extended again.

[0035] Further, the bottom of the dial 19 is arranged on the upper surface of the bottom plate inside the upper cover 2, so as to ensure that the pointer 20 can accurately move on the dial 19.

[0036] The basic principle, main features and advantages of the present application are shown and described above. It should be understood by those skilled in the art that the present application is not limited by the above examples, and the above examples and descriptions in the specification are only the principles of the present application. Without departing from the spirit and scope of the present application, various changes and improvements can be made to the present application, and these changes and improvements all fall within the scope of the claimed present application. The scope of protection required by the present application is defined by the appended claims and their equivalents.
