Description

Technical Field

[0001] This utility model relates to the field of bedding, specifically to a spring tilt angle measuring device. Background Technology

[0002] Mattress springs can tilt during manufacturing due to processing deviations, which significantly reduces the user experience. In the production workshop, on-site quality inspection of the springs is necessary. Current methods involve calculating the tilt angle using trigonometric functions from measured tilt lengths, requiring manual calculations and impacting inspection efficiency. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a spring tilt angle measuring device. A measuring rod and a protractor are set on a measuring platform. The tilt angle of the spring is directly obtained by using the measuring rod to fit against the side wall of the spring and cooperate with the protractor. This device is convenient for measurement, eliminates the need for manual calculation, ensures measurement accuracy, and improves the user experience.

[0004] This invention is achieved through the following method: a spring tilt angle measuring device, comprising a measuring platform, a protractor disposed below the measuring platform, and a measuring rod rotatably disposed on the measuring platform. The middle part of the measuring rod passes through the midpoint of the diameter side of the protractor via a pivot. The spring is placed on the measuring platform and its sidewall is in contact with the upper part of the measuring rod, allowing the lower part of the measuring rod to swing and cooperate with the protractor to obtain the tilt angle. By setting the measuring rod and protractor on the measuring platform, the measuring rod swings around the pivot and is in contact with the sidewall of the spring. The tilt angle of the measuring rod and the sidewall of the spring are the same, and the tilt angle can be directly obtained through the protractor. This method is convenient for measurement, eliminates the need for manual calculation, ensures measurement accuracy, and improves the user experience.

[0005] Preferably, the measuring platform is L-shaped, comprising a horizontal plate and a vertical plate. The top surface of the horizontal plate forms a support surface, and the spring rests on the support surface. The measuring rod abuts against the side wall of the spring and measures the tilt angle. The horizontal plate, through its support surface, supports the spring and limits its posture, ensuring that the bottom surface of the spring matches and fits the support surface, facilitating the measurement of the tilt angle of the spring's side wall using the measuring rod.

[0006] Preferably, the vertical plate has a vertically penetrating groove on its side wall facing the spring, allowing the upper part of the measuring rod to be embedded and hidden within the groove when it swings back to a vertical position. The vertical groove serves to conceal the measuring rod, protecting it and preventing it from bending due to external forces.

[0007] Preferably, the top edge of the vertical plate is provided with a limiting plate, which partially covers the upper opening of the vertical groove. The measuring rod swings to a vertical position and is positioned by its top end contacting the limiting plate, so that the upper part of the measuring rod is suspended and embedded in the vertical groove. The limiting plate can contact the top end of the measuring rod, which serves to limit the measuring rod, ensuring that the upper part of the measuring rod can be suspended and hidden in the vertical groove without contacting the groove wall. It also corrects the protractor, ensuring that the relative position between the protractor and the measuring stage is fixed, thus improving the accuracy of the test.

[0008] Preferably, the length of the upper part of the measuring rod is greater than the height of the vertical plate, so that the top of the measuring rod can abut against the limiting plate, thereby ensuring that the measuring rod can achieve vertical positioning by abutting against the limiting plate.

[0009] Preferably, the vertical plate has a length measuring scale on its side wall facing the spring for measuring the spring height. The bottom surface of the spring overlaps the supporting surface, allowing the top surface of the spring to be measured through the length measuring scale on the vertical plate, thus enhancing the user experience by adding the functionality of the measuring platform.

[0010] Preferably, the horizontal plate has a horizontal groove along its centerline. The horizontal groove and the vertical groove are in the same vertical plane. The diameter edge of the protractor is inserted into the horizontal groove and flush with the top surface of the horizontal plate. The fact that the horizontal groove and the vertical groove are in the same vertical plane facilitates the free swing of the measuring rod around the pivot point within the vertical plane. It also provides an installation position for the protractor, ensuring that the diameter edge of the protractor is flush with the top surface of the horizontal plate and that the diameter center of the protractor is concentric with the pivot point.

[0011] Preferably, the rotating shaft is arranged through the corner line of the measuring platform, so that the end of the rotating shaft is exposed, which facilitates disassembly and maintenance.

[0012] Preferably, the protractor is semi-circular, with its diameter edge closely fitting the bottom surface of the horizontal plate. The rotating shaft passes through the measuring rod and the protractor at its center and is inserted into the measuring platform at both ends. The rotating shaft passing through the midpoint of the diameter edge of the measuring rod and the protractor ensures that the measuring rod and the protractor can be connected to the measuring platform, and also ensures that the measuring rod can swing around the midpoint of the diameter edge of the protractor, thereby allowing direct reading of the tilt angle of the measuring rod via the protractor.

[0013] Preferably, the protractor and the bottom surface of the horizontal plate are set perpendicular to each other, ensuring that the lower part of the measuring rod always swings along the surface of the protractor, thereby improving the accuracy of tilt angle reading by reducing the distance between the lower part of the measuring rod and the protractor.

[0014] Preferably, the protractor has an angle measuring scale on its arc edge for reading the tilt angle of the measuring rod. The tilt angle of the measuring rod is read using the angle measuring scale, thereby obtaining the tilt angle of the spring sidewall.

[0015] The beneficial effects of this utility model are as follows: A measuring rod and a protractor are set on the measuring platform. The measuring rod swings around the pivot and fits against the side wall of the spring. The tilt angle between the measuring rod and the side wall of the spring is the same, and the tilt angle can be directly obtained through the protractor. This not only facilitates measurement and eliminates the need for manual calculation, but also ensures measurement accuracy and improves the user experience. Attached Figure Description

[0021] The essential features of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0022] like Figure 1 The device for measuring the tilt angle of a spring includes a measuring platform 1, a protractor 2 disposed below the measuring platform 1, and a measuring rod 3 rotatably mounted on the measuring platform 1. The middle part of the measuring rod 3 passes through the midpoint of the diameter side of the protractor 2 via a pivot 4. A spring 7 is placed on the measuring platform 1 and its sidewall is in contact with the upper part of the measuring rod 3, allowing the lower part of the measuring rod 3 to swing and cooperate with the protractor 2 to obtain the tilt angle. By setting the measuring rod 3 and the protractor 2 on the measuring platform 1, the measuring rod 3 swings around the pivot 4 and is in contact with the sidewall of the spring 7. The tilt angle of the measuring rod 3 and the sidewall of the spring 7 are the same, and the tilt angle can be directly obtained through the protractor 2. This method is convenient for measurement, eliminates the need for manual calculation, ensures measurement accuracy, and improves the user experience.

[0023] In actual operation, the measuring platform 1 is L-shaped, including a horizontal plate 5 and a vertical plate 6. The top surface of the horizontal plate 5 forms a supporting surface, and the spring 7 rests on the supporting surface. The measuring rod 3 abuts against the side wall of the spring 7 and measures the tilt angle. The horizontal plate 5 has a horizontal groove 10 opened along its centerline, and the vertical plate 6 has a vertical groove 8 opened along its centerline. The centerlines of the horizontal groove 10 and the vertical groove 8 are both located in the same vertical plane, so that the measuring rod 3 can swing freely in the vertical plane.

[0024] In actual operation, the connection between the horizontal plate 5 and the vertical plate 6 is provided with a mounting hole that runs through the corner line of the measuring platform 1. The middle part of the mounting hole is exposed at the junction of the horizontal groove 10 and the vertical groove 8. During installation, firstly, the diameter side of the protractor 2 is inserted into the horizontal groove 10, with the diameter side of the protractor 2 flush with the top surface of the horizontal plate 5, and the midpoint of the diameter side of the protractor 2 aligned with the mounting hole. Then, the measuring rod 3 with the adapter hole in the middle is installed on the measuring platform 1, with the measuring rod 3 vertically inserted at the junction between the horizontal groove 10 and the vertical groove 8, and the adapter hole aligned with the mounting hole. Finally, the rotating shaft 4 is inserted and fixed along the axis of the mounting hole so that the protractor 2 and the adapter hole are both fitted onto the rotating shaft 4.

[0025] After installation, the protractor 2 is fixedly connected to the measuring platform 1, and the measuring rod 3 can swing freely around the pivot 4. The measuring rod 3 is in a vertical position so that the upper part of the measuring rod 3 is hidden in the vertical groove 8.

[0026] In use, first, place the bottom surface of spring 7 onto the supporting surface. Rotate spring 7 so that the distance between the top surface of spring 7 and the vertical plate 6 is not less than the distance between the bottom surface of spring 7 and the vertical plate 6, facilitating the swing of measuring rod 3 and its contact with the side wall of spring 7. Then, move measuring rod 3; it will swing around pivot 4, ensuring at least two contact points between measuring rod 3 and the side wall of spring 7. Finally, read the corresponding angle measurement scale reading by observing the projection of the lower part of measuring rod 3 onto protractor 2 (e.g.,...). Figure 3 As shown in the figure, the tilt angle of spring 7 is obtained in this way.

[0027] In practice, because spring 7 has various different profiles, the number of contact points between the measuring rod 3 and the sidewall of spring 7 varies. When the spring 7 has a profile that is thicker at both ends and thinner in the middle, the measuring rod 3 will contact the edges of both ends of spring 7 and form two contact points (e.g., ...). Figure 2 (As shown); when the spring 7 has a cylindrical profile, the measuring rod 3 will contact each coil of the spring 7 and form contact points corresponding to the number of coils.

[0028] In actual operation, the vertical plate 6 has a vertically penetrating groove 8 on its side wall facing the spring 7. The upper part of the measuring rod 3 can be embedded and hidden in the vertical groove 8 when it swings back to a vertical state. The top edge of the vertical plate 6 has a limiting plate 9, which partially covers the upper opening of the vertical groove 8. When the measuring rod 3 swings to a vertical state, it is positioned by its top end contacting the limiting plate 9, so that the upper part of the measuring rod 3 is suspended and embedded in the vertical groove 8. The width of the vertical groove 8 is greater than the diameter of the measuring rod 3. The limiting plate 9 is set on the top surface of the vertical plate 6 and partially covers the upper opening of the vertical groove 8, ensuring that the measuring rod 3 is suspended in the vertical groove 8 after contacting the limiting plate 9 and will not contact the groove wall of the vertical groove 8, thus protecting the measuring rod 3. The length of the upper part of the measuring rod 3 is greater than the height of the vertical plate 6, so that the top end of the measuring rod 3 is exposed outside the upper opening of the vertical groove 8 and can contact the limiting plate 9.

[0029] In actual operation, the horizontal plate 5 is provided with a horizontal groove 10 along its centerline. The horizontal groove 10 and the vertical groove 8 are in the same vertical plane. The diameter side of the protractor 2 is inserted into the horizontal groove 10 and is flush with the top surface of the horizontal plate 5 (e.g., Figure 4 (As shown). The horizontal groove 10 provides installation space for the protractor 2, ensuring that the diameter edge of the protractor 2 can be flush with the top surface of the horizontal plate 5, and also provides swing space for the measuring rod 3.

[0030] In actual operation, the protractor 2 has an angle measurement scale on its arc edge for reading the tilt angle of the measuring rod 3. The protractor 2 is semi-circular, and its diameter edge is tightly fitted to the bottom surface of the horizontal plate 5. The rotating shaft 4 passes through the measuring rod 3 and the protractor 2 in the middle and is inserted into the measuring platform 1 at both ends. The protractor 2 includes an arc edge and a diameter edge. The arc edge has an angle measurement scale centered on the midpoint of the diameter edge. The midpoint of the diameter edge has a through hole for the rotating shaft 4 to pass through. The measuring rod 3 is connected to the midpoint of the diameter edge through the rotating shaft 4, so that the measuring rod 3 can swing around the midpoint of the diameter edge and directly read the tilt angle when in contact with the side wall of the spring 7. When installing the protractor 2, the bottom surfaces of the protractor 2 and the horizontal plate 5 are perpendicular to each other. The diameter side of the protractor 2 is flush with the top surface of the horizontal plate 5. At least two fixing points are provided between the protractor 2 and the measuring table 1 to ensure that the relative position between the protractor 2 and the horizontal plate 5 is fixed, thereby improving the accuracy of reading the tilt angle.

[0031] In actual operation, the vertical plate 6 has a length measuring scale on the side wall facing the spring 7 for measuring the height of the spring 7. The height of the top surface of the spring 7 is measured by using the length measuring scale, and the user experience is improved by adding the function of the measuring device.
