[0002] The tension spring is a type of spring. Its structure is larger than that of ordinary springs and it is always in a tensioned state when in use, ready to stretch the outer parts at any time.

[0003] The use of tension springs can improve the timely supplement of supporting force of components when facing external tension or pressure, thereby improving the stability of the overall component during operation. Therefore, it needs to be tested and qualified before it can be used in practice. However, the existing testing device simply judges whether it is qualified by subjecting it to continuous static pressure and then allowing it to rebound automatically, and observing the rebound process and whether the material is deformed. It is unable to accurately test it under a variety of different pressures, which affects the accuracy of the device's detection results and the diversity of the detection process.

[0004] Therefore, we provide a tension spring static pressure test device. Utility Model Content

There are several support slots 2. A pressure detection plate 12 is fixedly connected to the lower half of the support slot 2. The pressure detection plate 12 is electrically connected to a pressure display 13. The pressure display 13 is plugged into the support platform 1. Several plug interfaces 3 are opened at the upper end of the support platform 1. The support slot 2 is located between two plug interfaces 3. A connecting rod 4 is plugged into the plug interface 3. A limiting cap 5 is arranged between the two connecting rods 4. The limiting cap 5 is located directly above the support slot 2. A test spring 11 is arranged between the limiting cap 5 and the support slot 2. An adjusting bolt 9 is arranged between the two connecting rods 4. The adjusting bolt 9 is located at the lower end of the support platform 1. When the device is running, the test spring 11 is placed on the upper end of the pressure detection plate 12 inside the support slot 2, and then the limiting cap 5 is placed on the upper end of the test spring 11 to fix it. Then, the connecting rods 4 on both sides are plugged and fixed with the limiting cap 5 under the support of the support platform 1, and then the adjusting bolt 9 is rotated to make the two connecting rods 4 move toward the bottom of the device, so as to When the test spring 11 is connected with the limit cap 5, the test spring 11 is subjected to force compression. At this time, the pressure detection plate 12 will convert the pressure into the form of an electric wire number and transmit it to the pressure display 13, and then display it on the pressure display 13, so that the real-time pressure of the test spring 11 can be observed in time, and the limit cap 5 is driven downward by continuing to rotate the adjusting bolt 9. When the pressure of the test spring 11 reaches the detection data, the adjusting bolt 9 is stopped from rotating, so that the limit cap 5 is stationary under the pull of the connecting rod 4 to perform compression detection on the test spring 11. When the compression state of the test spring 11 is adjusted by the adjusting bolt 9 driving the connecting rod 4 and the limit cap 5, the test spring 11 can be tested under different pressure conditions, and the intuitive display effect of the pressure by the pressure detection plate 12 and the pressure display 13 can improve the accurate data of the pressure received by the device when detecting the test spring 11, thereby ensuring the stability of the test spring 11 in actual use, and improving the diversity of the device in the detection process and the accuracy of the detection results.

[0027] like Figure 1-Figure 4 As shown, the connecting rod 4 is plugged into the limiting cap 5 and extends to its upper end, and the upper end of the connecting rod 4 is threadedly screwed with a fastening cap 6, which is located at the upper end of the limiting cap 5, and a positioning column 10 is provided in the middle of the test spring 11, and the test spring 11 is plugged into the limiting cap 5. By placing the upper end of the test spring 11 inside the limiting cap 5 and the lower end of the test spring 11 outside the positioning column 10, it is possible to ensure that the test spring 11 is placed stably during testing and prevent the test spring 11 from popping out when compressed. At the same time, with the fastening effect of the fastening cap 6 on the connecting rod 4 and the supporting effect of the limiting cap 5, the stability of the connecting rod 4 when driving the limiting cap 5 to move is guaranteed, and when the limiting cap 5 is subjected to static pressure, the fastening cap 6 is rotated at different distances at the upper end of the connecting rod 4, so as to ensure the stability of the connection between the connecting rods 4 on both sides.

[0028] like Figure 1-Figure 4 As shown, a connecting plate 7 is fixedly connected to the lower end of the support platform 1. There are several connecting plates 7, and the connecting plates 7 are plugged into the connecting rods 4. The connecting plates 7 at the lower end of the support platform 1 guide and support the connecting rods 4 on both sides, thereby further improving the stability of the connecting rods 4 during movement and support.

[0029] Example 2

[0030] A static pressure test device for a tension spring, such as Figure 1-Figure 4 As shown, the adjusting bolt 9 is threadedly connected to the movable connecting plate 8 and extends to its upper end. The movable connecting plate 8 is fixedly connected to the connecting rod 4. The end of the adjusting bolt 9 away from the movable connecting plate 8 is rotatably connected to the connecting plate 7. The adjusting bolt 9 is located directly below the supporting groove 2. When the adjusting bolt 9 is rotated in a fixed position under the support of the connecting plate 7, the movable connecting plate 8 and the connecting plates 7 on both sides are driven to adjust their positions at the same time. The supporting effect of the connecting plate 7 on the adjusting bolt 9 ensures the stability of the position of the adjusting bolt 9 when it is rotated. By ensuring the convenience of adjusting the position of the movable connecting plate 8 and the connecting rods 4 on both sides, the timely adjustment of the test pressure by the device is improved.

[0031] like Figure 1-Figure 4 As shown, the connecting rod 4 is plugged with an auxiliary cap 14, and the auxiliary cap 14 is plugged with the two test springs 11 at the same time. By plugging and limiting the two test springs 11 with the auxiliary cap 14 at the same time, and driven by the connecting rods 4 on both sides, the effect of simultaneously detecting the two test springs 11 is achieved, and the effect of simultaneously detecting multiple test springs 11 is achieved by replacing auxiliary caps 14 of different specifications, thereby improving the effect of the device on detecting the combined test springs 11 when in use, thereby improving the diversity of the device's detection.

[0032] Working principle: by placing the test spring 11 on the upper end of the pressure detection plate 12 inside the support groove 2, and then placing the limit cap 5 on the upper end of the test spring 11 to fix it, and then by plugging and fixing the connecting rods 4 on both sides with the limit cap 5 under the support of the support platform 1, and then by rotating the adjusting bolt 9, the two connecting rods 4 are moved toward the bottom of the device, so that the test spring 11 is compressed under the connection of the limit cap 5. At this time, the pressure detection plate 12 will convert the pressure received into the form of an electric wire number and transmit it to the pressure display 13, and then display it on the pressure display 13, so that the real-time pressure received by the test spring 11 can be observed in time, and the limit is driven by continuing to rotate the adjusting bolt 9. The cap 5 moves downward, and when the pressure on the test spring 11 reaches the detection data, the adjusting bolt 9 stops rotating, so that the limit cap 5 is pulled by the connecting rod 4 to stationarily perform compression detection on the test spring 11. By adjusting the compression state of the test spring 11 driven by the adjusting bolt 9 to drive the connecting rod 4 and the limit cap 5, the test spring 11 can be tested under different pressure conditions, and the intuitive display effect of the pressure by the pressure detection plate 12 and the pressure display 13 can improve the accurate data of the pressure applied to the test spring 11 when the device is detecting it, thereby ensuring the stability of the test spring 11 during actual use and improving the diversity of the detection process of the device and the accuracy of the detection results.
