Description

Technical Field

[0001] This utility model relates to the field of spring testing, and in particular to a gauge for measuring the installation of seat cushion suspension springs. Background Technology

[0002] The seat cushion suspension spring is designed based on its installation on the seat cushion frame. To ensure a secure installation, the seat cushion suspension spring is designed with a preload. Therefore, the dimensions of the seat cushion suspension spring in its free state (not installed) differ from those in its installed state. To easily determine whether the seat cushion suspension spring meets the requirements, it is necessary to measure the dimensions of the seat cushion suspension spring in its installed state.

[0003] Existing seat cushion spring inspection tools directly use the seat cushion frame as the inspection tool, but the seat cushion springs are difficult to remove after installation, and may cause product deformation or even damage, rendering the product unusable. Utility Model Content

[0027] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0028] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0029] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0030] like Figure 1 and Figure 2 and Figure 3 As shown, a fixture for measuring the installation of seat cushion suspension springs includes a base plate 1 and a rotating mechanism 2, with the rotating mechanism 2 mounted on the base plate 1.

[0031] A central positioning body 11 and a positioning block 12 are provided on the base plate 1. The central positioning body 11 is located between the positioning block 12 and the rotating mechanism 2. The suspension spring 3 is laid flat on the base plate 1. The central positioning body 11, the positioning block 12 and the rotating rod 23 are used to fix the suspension spring 3 together.

[0032] The rotating mechanism 2 includes a first support block 21, a second support block 22, and a rotating rod 23. The first support block 21 and the second support block 22 are spaced apart on the base plate 1. The rotating rod 23 is rotatably mounted on the first support block 21 and the second support block 22. The suspension spring 3 is sleeved on the central positioning body 11. The two ends of the suspension spring 3 are respectively connected to the positioning block 12 and the rotating rod 23. When the rotating rod 23 is rotated, the suspension spring 3 is stretched. When the rotating rod 23 is rotated by a set angle, the rotating rod 23 stops rotating.

[0033] Then, various instruments are used to measure the suspension spring 3 in the tension state. After the test is completed, the rotating rod 23 is rotated in the opposite direction to reset the rotating rod 23. At the same time, the suspension spring 3 retracts to the natural state. The suspension spring 3 in the relaxed state is easy to take out. When installing or removing the suspension spring 3, it is simulated to install or remove the suspension spring 3 on the car seat. With such a test process, installation and disassembly, the suspension spring 3 is not easily damaged.

[0034] The rotating rod 23 is provided with a groove 24, which extends at both ends along the length of the rotating rod 23. The suspension spring 3 can be engaged in the groove 24. The groove 24 is pre-rotated to the vertical direction, and the opening end of the groove 24 is far away from the suspension spring 3. This makes it easy for the suspension spring 3 to be engaged in the groove 24. When the rotating rod 23 rotates, the suspension spring 3 is stretched or retracted.

[0035] The rotating rod 23 is equipped with a first lever 25 and a second lever 26 at both ends. The first lever 25 is located outside the first support block 21, and the second lever 26 is located outside the second support block 22. The operator can directly rotate the first lever 25 and the second lever 26, which saves effort.

[0036] The first support block 21 is provided with a first limiting rod 211 and a second limiting rod 212. The rotation range of the first lever 25 is between the first limiting rod 211 and the second limiting rod 212. That is, the first lever 25 can only rotate between the first limiting rod 211 and the second limiting rod 212, which means that the rotation angle of the lever 23 is limited.

[0037] The second support block 22 is provided with a third limiting rod 221 and a fourth limiting rod 222. The rotation range of the second lever 26 is between the third limiting rod 221 and the fourth limiting rod 222. That is, the second lever 26 can only rotate between the third limiting rod 221 and the fourth limiting rod 222, and the rotation angle of the second lever 26 is limited.

[0038] The central positioning body 11 is a cylinder. In other embodiments, the central positioning body 11 may also be a cube or a cone.

[0039] The positioning block 12 is provided with a positioning groove 13. The opening end of the positioning groove 13 is far away from the central positioning body 11, which is beneficial to the stretching or retraction of the suspension spring 3.

[0040] A pad 14 is provided on the base plate 1. The pad 14 is located between the positioning block 12 and the central positioning body 11. The pad 14 has an inclined surface 15. The high end of the inclined surface 15 is close to the positioning block 12, and the low end of the inclined surface 15 is close to the central positioning body 11. The pad 14 is used to support the suspension spring 3, and the inclined surface 15 is to match the shape of the suspension spring 3.

[0041] A top post 16 is provided on the base plate 1, and a clamping groove 17 is provided on the top post 16. The clamping groove 17 is used to clamp the suspension spring 3, so that the suspension spring 3 is not easy to shake. Multiple top posts 16 are provided, and multiple clamping grooves 17 are used to clamp the suspension spring 3 together.

[0042] The base plate 1 is also provided with a top block 18, which is used to lift the suspension spring 3. Multiple top blocks 18 are provided, and multiple top blocks 18 together support the suspension spring 3.

[0043] The base plate 1 is also provided with a first gripping ring 27 and a second gripping ring 28. The first gripping ring 27 and the second gripping ring 28 are respectively located at both ends of the base plate 1. The central positioning body 11 is located between the first gripping ring 27 and the second gripping ring 28. The first gripping ring 27 and the second gripping ring 28 are used for easy picking by the operator.

[0044] The base plate 1 is also provided with fixing holes 19 on its edge. Multiple fixing holes 19 are provided so that the base plate 1 can be easily fixed through the fixing holes 19.

[0045] The above embodiments are only for illustrating the technical concept and features of this utility model. Their purpose is to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be used to limit the protection scope of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the protection scope of this utility model.
