[0023] Example
[0024] This utility model provides a height measuring instrument, see [link to relevant documentation]. Figures 1 to 4 The device includes a telescopic ruler rod assembly 1, a measuring ruler 2, and a connecting assembly 3. The measuring ruler 2 is rotatably mounted on the telescopic ruler rod assembly 1 via the rotating connecting assembly 3. When storing the device, the measuring ruler 2 is rotated by adjusting the height of the telescopic ruler rod assembly 1 and by adjusting the rotating connecting assembly 3, thereby enabling the storage and carrying of the height measuring device.
[0025] By adopting the above solution, this utility model achieves rapid retraction or expansion of the measuring instrument by rotating the measuring ruler 2 to the telescopic ruler rod assembly 1 via the rotating connecting component 3; this utility model utilizes the telescopic performance of the telescopic ruler rod assembly 1 to make the measuring instrument easy to carry; this utility model has a simple design, saves a lot of time and costs, is convenient for patients to use, and is worth promoting.
[0026] See Figures 1 to 4 In a specific implementation of this utility model embodiment, the rotating connection assembly 3 further includes a connector 31 and an elastic element 32; a groove 13 is provided on the telescopic ruler rod assembly 1; the elastic element 32 is disposed in the groove 13, one end of the connector 31 is connected to the elastic element 32, and the other end is connected to the measuring ruler 2. The connector 31 is used to compress the elastic element 32; when the connector 31 compresses the elastic element 32, the connector 31 separates from the measuring ruler 2, at which time the measuring ruler 2 can rotate; when the connector 31 does not compress the elastic element 32, the connector 31 is connected to the measuring ruler 2, at which time the measuring ruler 2 cannot rotate.
[0027] Furthermore, the connector 31 is provided with a finger-operated gripper.
[0028] See Figure 3 and Figure 4 In a specific implementation of this utility model embodiment, the measuring ruler 2 is further provided with a plurality of positioning grooves 21, and the end of the connecting member 31 away from the groove 13 is engaged with the positioning groove 21. The connecting member 31 can be inserted into the positioning groove 21; when the connecting member 31 is connected to the positioning groove 21, the measuring ruler 2 cannot rotate; when the connecting member 31 is separated from the positioning groove 21, the measuring ruler 2 can rotate.
[0029] See Figures 1 to 4 In a specific implementation of this utility model embodiment, the telescopic ruler rod assembly 1 further includes a first ruler rod 11 and a second ruler rod 12. The first ruler rod 11 is connected to the second ruler rod 12 via a thread (not shown in the figure). The first ruler rod 11 and the second ruler rod 12 are telescopic, which facilitates folding and thus makes them easy to carry.
[0030] In a specific implementation of this utility model embodiment, one end of the connector 31 away from the groove 13 extends to the outside of the first scale rod 11 to form an extension portion, which is connected in conjunction with several positioning grooves 21. When the extension portion is inserted into the positioning groove 21, the measuring scale 2 cannot be rotated.
[0031] In a specific implementation of this embodiment, the end of the connector 31 away from the groove 13 extends to the outside of the second scale rod 12 to form an extension, which is connected to several positioning grooves 21. When the extension is inserted into the positioning groove 21, the measuring scale 2 cannot be rotated.
[0032] Furthermore, in this utility model, grooves 13 can be provided on both the first scale rod 11 and the second scale rod 12, so that the connecting member 31 can form an extension on both the first scale rod 11 and the second scale rod 12.
[0033] See Figures 1 to 4 In a specific implementation of this utility model embodiment, the surfaces of both the first ruler rod 11 and the second ruler rod 12 are provided with scale lines. The scale lines are used to facilitate the measurement of the user's height or other length information.
[0034] See Figures 1 to 4 In a specific implementation of this utility model embodiment, the diameter of the first scale rod 11 is smaller than the diameter of the second scale rod 12. This arrangement facilitates the retraction of the first scale rod 11 into the second scale rod 12.
[0035] Furthermore, the cross-sections of the first ruler rod 11 and the second ruler rod 12 can be circular or rectangular, etc., and a square cross-section is used in this embodiment of the present invention.
[0036] Furthermore, when stored, the first ruler rod 11 is located inside the second ruler rod 12. This retraction reduces the size of the telescopic ruler rod assembly 1, making it easier to carry.
[0037] The working principle of the height measuring instrument provided in this embodiment of the utility model is as follows:
[0038] When unfolding, firstly, the first ruler rod 11 is pulled out from the second ruler rod 12, and then the finger-clamping platform on the connecting piece 31 is engaged, causing the connecting piece 31 to compress the elastic element 32, thereby causing the extension on the connecting piece 31 to separate from the positioning groove 21; then the measuring ruler 2 is rotated, and the measuring ruler 2 is perpendicular to the telescopic ruler rod assembly 1. The finger-clamping platform is released, and the extension on the connecting piece 31 enters the positioning groove 21 under the action of the elastic element 32, and the measuring ruler 2 is fixed; thus completing the unfolding process of the height measuring instrument.
[0039] During retraction, firstly, the first ruler rod 11 is retracted into the second ruler rod 12. Then, the finger-grip on the connector 31 is engaged, causing the connector 31 to compress the elastic element 32, thereby separating the extension on the connector 31 from the positioning groove 21. Next, the measuring ruler 2 is rotated, becoming parallel to the telescopic ruler rod assembly 1. The finger-grip is released, and the extension on the connector 31 enters the positioning groove 21 under the action of the elastic element 32, thus fixing the measuring ruler 2. This completes the retraction process of the height measuring instrument.
[0040] In summary, this invention achieves rapid retraction or expansion of the measuring instrument by rotatably connecting the measuring ruler 2 to the groove 13 on the telescopic ruler rod assembly 1 via the connecting piece 31 in the rotating connecting assembly 3, and by connecting or separating the connecting piece 31 from the positioning groove 21 on the measuring ruler 2; this invention utilizes the telescopic properties of the first ruler rod 11 and the second ruler rod 12 to achieve the function of convenient carrying of the measuring instrument; this invention has a simple design, saves a lot of time and costs, is convenient for patients to use, and is worthy of promotion and use.
[0041] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
