Description

Technical Field

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

[0002] Dimensional measurement is a critical step in the development of automotive suspensions. It not only affects the dynamic characteristics and positioning accuracy of the suspension system but also directly impacts the overall performance and driving experience of the vehicle. Therefore, during the suspension development process, attention must be paid to the accuracy and method of dimensional measurement to ensure optimal performance of the suspension system and vehicle safety. When measuring dimensions such as the height and ground clearance of automotive suspensions, existing height gauges are inadequate due to the complex underbody structure and limited space. Instead, conventional tape measures are used, but these cannot guarantee verticality, resulting in significant measurement errors that significantly impact subsequent automotive suspension development and use. Utility Model Content

[0003] In order to solve at least one aspect of the above-mentioned problems, the present invention provides a telescopic height gauge, comprising a base plate, a fixed cylinder, a ruler tube and a measuring rod; the base plate is arranged horizontally; the fixed cylinder is arranged vertically, and the bottom end of the fixed cylinder is fixedly connected to the base plate; the ruler tube is arranged vertically and passed through the fixed cylinder, and the ruler tube and the fixed cylinder are slidably connected along the vertical direction; the surface of the ruler tube is marked with scales along the vertical direction; the measuring rod is arranged horizontally, and the first end of the measuring rod is connected to the top end of the ruler tube.

[0004] Through the above technical solution, after determining the target to be measured, the base plate of the height gauge of the present application is placed horizontally near the location of the target, and then the ruler tube is extended. The measuring rod is aligned with the target to be measured, and the height of the target to be measured is measured by reading the scale on the measuring rod. The measurement process is simple and the measurement results are accurate. Since the overall size of the height gauge of the present application is small when the ruler tube is in the retracted state, the height gauge of the present application can be placed in a relatively small space before use. In addition, the measuring rod is designed in the height gauge of the present application, so that the height gauge body of the present application does not need to be close to the target to be measured, which helps to improve the flexibility of the position selection when the height gauge of the present application is measured. Therefore, the height gauge of the present application has a simple structure, is easy to operate, and has accurate measurement results. It is suitable for use in places with complex structures and small spaces.

[0005] Preferably, a level is connected to the top surface of the base plate. The above technical solution provides a level on the base plate, which, on the one hand, helps the base plate to be quickly leveled, and on the other hand, helps ensure that the base plate is level, thereby ensuring that the fixing tube and the ruler are in a vertical state and the measuring rod is in a horizontal state, which helps improve the accuracy of the measurement results.

[0006] Preferably, two opposing points on the top sidewall of the ruler tube have connecting holes extending therethrough; the measuring rod comprises a positioning end, a first section, and a second section, which are sequentially connected; the positioning end is larger than the connecting holes and abuts against the outer sidewall of the top sidewall of the ruler tube; the first section has threads on its surface and extends through both connecting holes; a fixing nut is threadedly connected to the end of the first section away from the positioning end, and the fixing nut abuts against the outer sidewall of the top sidewall of the ruler tube. The above technical solution discloses a specific method for connecting the measuring rod to the ruler tube. By designing the measuring rod and the ruler tube to be detachably connected, it facilitates replacement of the measuring rod to accommodate measurements of different part heights.

[0007] Preferably, a support tube is provided inside the ruler tube. The size of the support tube is greater than or equal to the size of the connecting hole. The two ends of the support tube correspond to the two connecting holes and are fixedly connected to the inner wall of the ruler tube. The first section is inserted into the support tube. Through the above technical solution, the support tube is designed inside the ruler tube to support the ruler tube and prevent deformation of the ruler tube.

[0008] Preferably, the second end of the measuring rod is a pointed structure, which helps to improve the accuracy of alignment between the measuring rod and the target to be measured, thereby improving the accuracy of the measurement result.

[0009] Preferably, at least three vertical support columns are provided below the base plate, and the top end of each support column is fixedly connected to the bottom surface of the base plate, which helps to increase the measuring range of the height gauge of the present application.

[0010] Preferably, a first sliding sleeve is sleeved on the bottom end of the ruler tube. The inner wall of the first sliding sleeve is fixedly connected to the outer wall of the ruler tube. The cross-sectional shape and size of the outer wall of the first sliding sleeve match the cross-sectional shape and size of the inner wall of the fixed tube. The outer wall of the first sliding sleeve and the inner wall of the fixed tube are vertically slidably connected. The side wall of the first sliding sleeve is provided with at least one first channel extending vertically and passing through the top and bottom surfaces of the first sliding sleeve. Through the above technical solution, a specific structure for the sliding connection between the ruler tube and the fixed tube is disclosed. The sliding connection between the ruler tube and the fixed tube is achieved through the first sliding sleeve. By providing a first channel in the first sliding sleeve for air circulation, the air pressure inside and outside the fixed tube is balanced when the ruler tube is extended or retracted, ensuring smooth movement of the ruler tube within the fixed tube.

[0011] Preferably, a second sliding sleeve is provided on the inner wall of the top end of the fixed cylinder, the outer wall of the second sliding sleeve is fixedly connected to the inner wall of the fixed cylinder, the shape and size of the cross-section of the inner wall of the second sliding sleeve match the shape and size of the cross-section of the outer wall of the ruler tube, and the outer wall of the ruler tube and the inner wall of the second sliding sleeve are slidably connected along the vertical direction; at least one second channel extending along the vertical direction and passing through the top and bottom surfaces of the second sliding sleeve is opened on the side wall of the second sliding sleeve, which helps to improve the smoothness and stability of sliding.

[0012] Preferably, a base is provided on the top surface of the base plate, the base comprising a horizontal plate and a vertical sleeve, the cross-sectional shape and size of the inner wall of the vertical sleeve matching the cross-sectional shape and size of the outer wall of the bottom end of the fixed tube, the bottom end of the vertical sleeve being fixedly connected to the top surface of the horizontal plate; the horizontal plate is fixedly connected to the base plate, the bottom end of the fixed tube is inserted into the vertical sleeve, and the bottom end of the fixed tube is fixedly connected to the vertical sleeve. The above technical solution discloses a specific method for connecting the fixed tube to the base plate, which ensures that the fixed tube is in a vertical state when the base plate is horizontally arranged by means of the mutually perpendicular horizontal plate and vertical sleeve.

[0013] Preferably, a top cover is detachably connected to the top end of the ruler tube.

[0014] The telescopic height gauge of the utility model has the following beneficial effects:

[0015] By designing a base connected to a vertical fixed cylinder on a horizontally arranged bottom plate, and designing a ruler tube connected to the fixed cylinder in a vertical sliding manner, it is possible to realize that after determining the target to be measured, the bottom plate of the height gauge of the present application is first placed horizontally near the location of the target, and then the ruler tube is extended to measure. Since the overall size of the height gauge of the present application is small when the ruler tube is in a retracted state, the height gauge of the present application can be placed in a relatively narrow space before use; a horizontally arranged measuring rod is designed on the top of the ruler tube, so that the height gauge of the present application does not need to be close to the target to be measured, and the measuring rod is used to align with the target to be measured and then the height gauge is measured according to the measurement result. The ruler tube reading helps to improve the flexibility of the position selection when measuring the height ruler of this application; by designing the measuring rod to be detachably connected to the ruler tube, it is possible to replace the measuring rod that is compatible with the target to be measured, and the second end of the measuring rod is designed to be a pointed structure, which helps to improve the accuracy of the alignment of the measuring rod with the target to be measured, thereby improving the accuracy of the measurement result; by installing a level on the base plate, it is ensured that the fixed tube and the ruler tube are in a vertical state and the measuring rod is in a horizontal state, which helps to improve the accuracy of the measurement result; by designing a detachable support column on the bottom surface of the base plate, it helps to increase the measuring range of the height ruler of this application. Therefore, the height ruler of this application has a simple structure, easy operation, accurate measurement results, and is suitable for use in places with complex structures and narrow spaces.
