Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Example

[0024] like Figure 1-3As shown, a planar scroll spring test fixing structure proposed in one embodiment of the utility model comprises a base 1, the base 1 is slidably engaged on a rail seat 2, a scale line 3 is provided on the side of the rail seat 2, an L-shaped block 4 is fixedly connected to the side rear edge of the base 1, a bearing seat 6 is fixedly connected to the base 1, a screw 7 is rotatably connected to the bearing seat 6, one end of the screw 7 is fixedly connected to a hand wheel 8, a screw block 9 is threadedly connected to the screw 7, a fixing block 10 is fixedly connected to the screw block 9, one of the fixing blocks 10 is rotatably connected to a mounting column 11, and the other fixing block 10 is rotatably connected to a connecting column 12, and one end of the connecting column 12 is fixedly connected to a fixing head 13;

[0025] The base 1 is slidably engaged on the rail base 2, so that the base 1 can be flexibly moved on the rail base 2 to achieve position adjustment.

[0026] A scale mark 3 is provided on the side of the rail seat 2, which provides an accurate position reference for the movement of the base 1 and facilitates accurate setting of the test position.

[0027] An L-shaped block 4 is fixedly connected to the rear side of the base 1 to assist in fixing the position of the base 1 .

[0028] A bearing seat 6 is fixedly connected to the base 1, and a screw rod 7 is rotatably connected to the bearing seat 6, which provides a support and rotation basis for the adjustment component.

[0029] One end of the screw rod 7 is fixedly connected to a hand wheel 8 to facilitate manual operation to rotate the screw rod 7.

[0030] The screw rod 7 is threadedly connected to a screw block 9, and the screw block 9 is fixedly connected to a fixed block 10: the screw block 9 is driven to move by the rotation of the screw rod 7 to adjust the spacing.

[0031] One of the fixing blocks 10 is rotatably connected to the mounting column 11 , and the other fixing block 10 is rotatably connected to the connecting column 12 : the mounting column 11 and the connecting column 12 are allowed to rotate within a certain range to meet different installation angle requirements.

[0032] One end of the connecting column 12 is fixedly connected to a fixing head 13 , and the fixing head 13 is provided with a clamping groove 14 for fixing one end of the spring.

[0033] Here’s how it works:

[0034] First, according to the length of the plane scroll spring to be tested and the test requirements, slide the base 1 along the rail seat 2, and accurately determine the position of the base 1 through the scale line 3 on the side of the rail seat 2. After the position is determined, tighten the bolts 5 on the L-shaped block 4 to firmly fix the base 1 on the rail seat 2.

[0035] Next, the screw rod 7 is rotated by turning the hand wheel 8. Since the screw rod 7 is provided with opposing threads, the two screw blocks 9 will move toward or away from each other when the screw rod 7 rotates. The movement of the screw block 9 drives the fixed block 10 to move, thereby changing the distance between the mounting column 11 and the connecting column 12.

[0036] Place one end of the plane scroll spring in the slot 14 of the fixing head 13, and continue to turn the hand wheel 8 to gradually reduce the distance between the mounting column 11 and the connecting column 12 until the fixing head 13 tightly clamps one end of the spring to achieve a firm fixation of the spring.

[0037] During the entire test process, since the base 1 is fixed in position and the fixing head 13 reliably clamps the spring, it can be ensured that the spring will not be displaced or twisted when subjected to the test force, thereby ensuring the accuracy of the test results.

[0038] like Figure 2 As shown, in some embodiments, the L-shaped block 4 is threaded with a bolt 5, and the bolt 5 penetrates the L-shaped block 4 and is fixed on the base 1; as the bolt 5 is continuously tightened, its front end will contact the base 1 and generate sufficient friction and pressure, thereby tightly fixing the base 1 on the rail seat 2, preventing the base 1 from accidentally sliding or displacing due to external forces or vibrations during the test, thereby ensuring the accuracy and stability of the test.

[0039] like Figure 2 As shown, in some embodiments, the screw rod 7 is provided with opposing threads; opposing threads mean that the threads of different parts are in opposite directions on the same axis of the screw rod 7. When the screw rod 7 rotates, due to the opposite directions of the threads, the two screw blocks 9 threadedly connected to the screw rod 7 will move towards or away from each other at the same time.

[0040] like Figure 3 As shown, in some embodiments, the fixing head 13 is provided with a clamping groove 14; the main purpose of the clamping groove 14 is to clamp one end of the plane scroll spring more firmly and accurately. Its design allows one end of the spring to be embedded in the clamping groove 14, increasing the contact area and friction, thereby effectively preventing the spring from slipping off or shifting from the fixing head 13 during the test.

[0041] like Figure 3 As shown, in some embodiments, the clamping slot 14 is a symmetrical structure, clamping one end of the scroll spring; the symmetrical clamping slot 14 can evenly apply clamping force from both sides when clamping one end of the spring, ensuring that the spring is balanced in force during the fixing process. This balanced clamping force helps prevent the spring from being skewed in the clamping slot 14 or deformed due to excessive local force.

[0042] like Figure 3As shown, in some embodiments, the diameter of the fixing head 13 is matched with the inner diameter of the scroll spring; the matched diameter can ensure that the fixing head 13 is tightly fitted with the inner diameter of the scroll spring. In this way, during the test, the inner part of the spring can be firmly supported and fixed to avoid shaking or deviation when subjected to force, thereby ensuring the accuracy and reliability of the test results.

[0043] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
