[0029] Example: Figure 1-4 As shown, this utility model provides a technical solution, a device for testing the tensile strength of a corrugated pipe, including a support frame 1, and a fixing component 2 is installed at the top of the support frame 1;

[0030] The fixing component 2 includes a fixing rod 201, a movable sliding groove plate 202, a fixing arc electromagnet 203, a clamping arc plate 204, an extension groove 205, an extension slide rod 206, a toggle plate 207, a movable electromagnet 208, and a fixing sliding groove plate 209.

[0031] A fixed rod 201 is welded to one end face of the support frame 1. A movable sliding groove plate 202 is welded to one end of the fixed rod 201. A fixed arc electromagnet 203 is installed on one end face of the movable sliding groove plate 202. A clamping arc plate 204 is attracted to the outside of the fixed arc electromagnet 203. There are two clamping arc plates 204. The two clamping arc plates 204 are attracted to the outer arc surfaces of the fixed arc electromagnet 203 and the movable electromagnet 208 respectively, which is beneficial for fixing the bellows.

[0032] An extension groove 205 is provided on the inner side of the movable sliding groove plate 202. An extension slide rod 206 is slidably installed on the inner side of the extension groove 205. A toggle piece 207 is welded to one end face of the extension slide rod 206. Two toggle pieces 207 are welded on each other and symmetrically on the two end faces of the extension slide rod 206, which facilitates the rapid sliding of the extension slide rod 206. A movable electromagnet 208 is installed at one end of the extension slide rod 206. A fixed sliding groove plate 209 is installed at a symmetrical position on the movable sliding groove plate 202. A tension moving seat is installed at the bottom end of the support frame 1. A tension moving seat is symmetrically installed at the bottom end of the fixed sliding groove plate 209 and at the corresponding position of the support frame 1, which facilitates the rapid stretching of the corrugated pipe.

[0033] A sliding component 3 is installed at the bottom end of the fixed sliding groove plate 209;

[0034] The sliding assembly 3 includes a positioning base 301, a fixed slide rail 302, a threaded groove 303, an extension threaded rod 304, an extension slide rail 305, and a limiting slide block 306;

[0035] A positioning base 301 is provided at the bottom of the fixed sliding groove plate 209. A fixed slide rail 302 is welded to one end face of the positioning base 301. Two fixed slide rails 302 are provided and symmetrically welded to one end face of the positioning base 301. The support frame 1 is slidably connected to the fixed slide rail 302 through the bottom tension moving seat, which facilitates the pulling of corrugated pipes of different lengths. A threaded groove 303 is opened on the inner side of the fixed slide rail 302. An extension threaded rod 304 is threadedly connected to the inner side of the threaded groove 303. An extension slide rail 305 is welded to one end of the extension threaded rod 304. A limit slide seat 306 is slidably installed on the outer side of the extension slide rail 305.

[0036] The working principle and usage process of this utility model are as follows: First, before conducting a tensile test on the corrugated pipe, the operator can remove the clamping arc plates 204 on both sides, and then attach the fixed arc electromagnet 203 to the inner wall of the corrugated pipe to open one side of the corrugated pipe. Then, by moving the actuating plate 207, the extension slide rod 206 can be moved outward on the inner side of the extension groove 205. Then, the movable electromagnet 208 can be attached to the other side of the inner wall of the corrugated pipe to open the corrugated pipe. Then, the two clamping arc plates 204 can be attached to the corresponding positions of the fixed arc electromagnet 203 and the movable electromagnet 208 on the outer side of the corrugated pipe. At this time, the fixed arc electromagnet 203 and the movable electromagnet 208 are turned on to attract the clamping arc plates 204 on the outer side, thus clamping and fixing the corrugated pipe.

[0037] Next, by fixing the arc-shaped electromagnet 203 and the movable electromagnet 208 and the clamping arc-shaped plate 204 on the outside, one end of the bellows can be fixed. Then, the other end of the bellows is fixed on the outside of the fixed sliding groove plate 209. At this time, both ends of the bellows can be fixed. When the inner diameter of the bellows to be tested is different, the position of the extension rod 206 can be slid to quickly adjust the total length to suit bellows with different inner diameters, further improving the applicability of the testing device and improving the testing efficiency.

[0038] Finally, when stretching is required, the limiting slide block 306 can be continuously pulled on the outside of the fixed slide rail 302, thereby driving the support frame 1 and the movable sliding groove plate 202 to move. At this time, the bellows can be continuously stretched. When the length of the bellows to be stretched is different, the extension slide rail 305 can be tightened to the inside of the threaded groove 303 through the extension threaded rod 304, thereby extending the total length of the fixed slide rail 302 to test bellows of different lengths and improve the applicability of the test.

[0039] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model.
