Description

Technical Field

[0001] This utility model relates to a measuring device, and in particular to a height and weight scale. Background Technology

[0002] A height and weight scale is a device that measures height and weight. Currently, the most common height measurement methods are ultrasonic and lever-type. The first type has an upward-extending vertical bar and a horizontal bar extending from the top of the vertical bar. An ultrasonic probe is installed inside the horizontal bar. The measurement principle is to use the ultrasonic probe to emit signals and detect the vertical distance between the probe and the top of the person's head, thus calculating the height. While this method is accurate, its manufacturing cost is relatively high. Furthermore, the height of the ultrasonic probe is pre-set at the factory, so the horizontal and vertical bars are usually molded as a single piece, making it impossible to fold or retract the vertical bar, which is inconvenient for transportation. The second type, the lever-type, includes at least two vertical bars connected together. A horizontal bar slides along one of the vertical bars. In use, the horizontal bar slides vertically along the vertical bar, pressing against the person's head to detect their height. However, after adjusting the height, a manually adjustable locking mechanism is required between the horizontal and vertical bars. This method is not only cumbersome to operate but also structurally complex and difficult to assemble. Utility Model Content

[0003] In order to overcome the shortcomings of the existing technology, this utility model provides a height and weight scale that is easy to assemble.

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0024] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.

[0025] The following describes some embodiments of the present invention with reference to the accompanying drawings.

[0026] Reference Figures 1 to 7 A height and weight scale that is easy to assemble includes a scale body 1, a panel 11 mounted on the scale body 1, an outwardly extending arc portion 12 on one side of the panel 11, a base 2 mounted on the arc portion 12, a vertical rod 3 inserted into the base 2, a pressure rod 4 slidably mounted on the vertical rod 3, and a locking mechanism installed inside the pressure rod 4; the pressure rod 4 is provided with a hollow hole 41 adapted to the shape of the vertical rod 3, and after assembly, the hollow hole 41 fits onto the outer side wall of the vertical rod 3. The assembly structure is simple and easy to assemble.

[0027] The base 2 is provided with a support part 21, and a connecting column 22 is provided in the middle of the support part 21. The connecting column 22 is provided with a mounting groove 23. After assembly, the bottom of the vertical rod 3 extends into the mounting groove 23, and the assembly structure is simple.

[0028] In this embodiment, the pressure rod 4 can be disassembled and assembled along the top of the vertical rod 3 through the hollow hole 41, facilitating retraction and transportation. Furthermore, the vertical rod 3 can be constructed by splicing together several vertical rods. For example, a common vertical rod 3 can be divided into an upper vertical rod, a middle vertical rod, and a lower vertical rod. The lower end of the upper vertical rod is connected to the upper end of the middle vertical rod, the lower end of the middle vertical rod is connected to the upper end of the lower vertical rod, and the lower end of the lower vertical rod is connected to the base. Specifically, a common plug-in structure can be used for easy assembly and storage.

[0029] The pressure rod 4 has a hollowed-out hole 42 that extends horizontally through the hollow hole 41. A bracket 43 with a central hollow section is installed at the opening of the hollowed-out hole 42. The side walls of the bracket 43 have inwardly protruding indicator portions 44. In this embodiment, the side walls of the vertical rod 3 have scale values ​​for measuring height. When measuring height, the scale value indicated by the indicator portion 44 is the measured height value, making it convenient for the user to view the height. Furthermore, the bracket 43 and the hollowed-out hole 42 can be connected by a common snap-fit ​​structure for easy assembly.

[0030] The locking mechanism includes a slider 5, one side of which abuts against the outer wall of the vertical rod 3, and the other side is equipped with an arc-shaped spring 6. In its natural state, the spring 6 elastically extends and retracts, and the slider 5 bends toward one side of the vertical rod 3, so that the slider 5 makes frictional contact with the outer wall of the vertical rod 3.

[0031] Specifically, when measuring height, the pressure bar 4 slides vertically along the vertical rod 3. At this time, the sliding piece 5 slides and rubs against the outer wall of the vertical rod 3. Since the sliding piece 5 is made of soft materials such as plastic, it deforms due to friction. At this time, the spring piece 6 also undergoes elastic deformation, stretching upward and downward, causing the sliding piece 5 to bend towards the side of the spring piece 6, reducing the frictional resistance with the vertical rod 3 and facilitating sliding. In the natural state, after the pressure bar 4 is adjusted to the correct height, the spring piece 6 recovers its elasticity and contracts towards the center, causing the sliding piece 5 to bend towards the side of the vertical rod 3, allowing the sliding piece 5 to re-rub against the outer wall of the vertical rod 3. The pressure bar 4 is automatically positioned through friction, eliminating the need for manual locking by the user and making it convenient for the user.

[0032] The slider 5 is I-shaped and includes a tension part 51 and a connecting part 52 integrally formed on the upper and lower sides of the tension part 51. The tension part 51 is provided with an outwardly protruding contact part 53 on the side facing the vertical rod 3. After assembly, the contact part 53 abuts against the outer wall of the vertical rod 3. The frictional contact between the contact part 53 and the outer wall of the vertical rod 3 further increases the frictional resistance.

[0033] The spring piece 6 includes an elastic part 61 and an integrally formed insertion part 62 located on the upper and lower sides of the elastic part 61. The tension part 51 is provided with a vertically symmetrical insertion seat 54 on the side facing the spring piece 6. The insertion seat 54 is provided with an insertion groove 55. After assembly, the insertion part 62 is inserted into the insertion groove 55. In this embodiment, when the elastic part 61 elastically deforms, the elastic part 61 applies pressure to the upper and lower ends, causing the slider 5 to elastically deform accordingly. The slider 5 bends towards the side of the spring piece 6, reducing the frictional resistance with the vertical rod 3 and facilitating sliding. When the elastic part 61 elastically recovers, the elastic part 61 contracts towards the middle, causing the slider 5 to return to its original shape, and the frictional resistance between the slider 5 and the vertical rod 3 is restored.

[0034] The inner sidewall of the pressure rod 4 is provided with a connecting groove 45 corresponding to the connecting part 52. After assembly, the connecting part 52 of the slider 5 is inserted into the connecting groove 45, which on the one hand prevents the slider 5 from falling off during sliding, and on the other hand simplifies the assembly structure.

[0035] The scale body 1 and the panel 11 are bonded together. The bottom of the base 2 has several threaded posts, and the arc-shaped portion 12 has several through holes 121 corresponding to the threaded posts. After assembly, screws pass through the through holes 121 and are threadedly connected to the threaded posts, resulting in a simple assembly structure. In this embodiment, because the scale body 1 and the panel 11 are bonded together, conventional electronic scales also include a scale body 1 and a panel 11 during production. The difference is that the panel does not have the arc-shaped portion 12. Therefore, when producing height and weight scales, the panel 11 with the arc-shaped portion 12 can be replaced, upgrading the original electronic scale and reducing production costs. Conversely, the panel 11 of a height and weight scale can be replaced with a panel for electronic scales, allowing the scale body to be used as a single weight scale.
