Detailed Implementation

[0029] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0030] like Figure 1 and Figure 2 As shown, an exhaust pipe testing tool according to one embodiment of the present invention includes a fixing component 1, which includes a base 101. A fixing clamp 102 for fixing the exhaust pipe is installed on the top end face of the base 101. A support component 2 is installed on one side wall of the fixing component 1. A test component 3 is slidably connected to the inner wall of the support component 2. Limiting components 4 matching the test component 3 are installed on both sides of the inner wall of the support component 2. A control component 5 is threadedly connected to the bottom end of each set of limiting components 4. The height and position of the test component 3 are adjusted and fixed by the cooperation of the test component 3 and the limiting components 4. The operation is simple. The test component 3 is controlled to fall by the control component 5 to realize the testing of the exhaust pipe.

[0031] like Figures 2-5As shown, the test assembly 3 includes an impact block 301, the outer wall of which is attached to the inner wall of a pair of limiting plates 202. A first auxiliary block 302 is integrally formed on both sides of the impact block 301. A connecting rod 303 is hinged to one side wall of the first auxiliary block 302, and a second auxiliary block 304 is hinged to the other end of the connecting rod 303. The support assembly 2 includes a support column 201, a pair of limiting plates 202 integrally formed on one side wall of the support column 201. Vertical grooves 2021 are formed on the outer walls of the pair of limiting plates 202. The outer wall of the first auxiliary block 302 slides on the inner wall of the vertical groove 2021. The bottom end face of the pair of limiting plates 202... The entire assembly is integrally formed with a horizontal plate 203. A horizontal groove 2031 is provided on the bottom end face of the horizontal plate 203. The outer wall of the second auxiliary block 304 slides on the inner wall of the horizontal groove 2031. A handle 3031 is fixedly connected to the outer wall of the connecting rod 303. When the operator performs an impact test on the exhaust pipe, he first pulls the handle 3031 to drive a pair of second auxiliary blocks 304 to slide on the inner wall of the slide groove 2032. The smaller the distance between the two sets of second auxiliary blocks 304, the higher the height of the impact block 301. After adjusting to a suitable height, the position of the second auxiliary block 304 is fixed under the action of the control component 5, thereby determining the height of the impact block 301.

[0032] like Figures 6-8 and Figure 4As shown, the limiting component 4 includes a pair of hollow shells 401. Several sets of guide blocks 403 are slidably connected to one side wall of each hollow shell 401. A sliding groove 2032 is provided on each pair of side walls of the horizontal plate 203 located in the horizontal groove 2031. The upper and lower end faces of the hollow shell 401 slide on the inner walls of the sliding grooves 2032. Several sets of upper and lower grooves 4011 are provided on the upper and lower end faces of the hollow shell 401. Several sets of side grooves 4012 are provided on the side walls of the hollow shell 401. A locking block 402 is fixedly connected to the inner wall of the hollow shell 401 located in the side groove 4012. A guide block 403 is fixedly connected to one side wall of the locking block 402. The upper and lower end faces are integrally formed with sliders 4031. The outer wall of sliders 4031 slides on the inner wall of the upper and lower grooves 4011. The bottom end face of the hollow shell 401 is integrally formed with a threaded block 404 that matches the control component 5. The outer end face of the guide block 403 slides on the inner wall of the side groove 4012. One side wall of the second auxiliary block 304 is attached to one side wall of the guide block 403. A circular groove 2033 is opened on the bottom side wall of the horizontal plate 203. A square groove 2034 is opened on the side wall of the horizontal plate 203 located in the sliding groove 2032 and the circular groove 2033. The outer wall of the threaded block 404 slides on the inner wall of the square groove 2034. When the second auxiliary block 304 slides on the inner wall of the transverse groove 2031, when the second auxiliary block 304 passes the inclined side wall of the guide block 403, the guide block 403 is driven to slide into the side groove 4012 because the side wall of the guide block 403 is inclined. When the guide block 403 is fully inside the side groove 4012, the second auxiliary block 304 passes smoothly. Then, the guide block 403 returns to the initial position under the action of the locking block 402. After adjusting the second auxiliary block 304 to a suitable position, the sliding stops, so that one side wall of the second auxiliary block 304 is attached to the other side wall of the guide block 403. At this time, the guide block 403 will not move inward. The second auxiliary block 304 will only drive the guide block 403 to move inward when it slides from the inclined side wall of the guide block 403. In the opposite direction, the guide block 403 plays a limiting role, thereby realizing the fixation of the test component 3 and completing the adjustment of the height of the test component 3.

[0033] like Figures 6-7As shown, the control assembly 5 includes a control lever 501. A bidirectional threaded rod 502 is integrally formed on one side wall of the control lever 501. A circular groove 2033 is formed on the bottom side wall of the horizontal plate 203. The control lever 501 and the bidirectional threaded rod 502 rotate within the circular groove 2033. A threaded block 404 is threadedly connected to the bidirectional threaded rod 502. A knob 503 is integrally formed on one side wall of the control lever 501. A steel rope 504 is fixedly connected to the side wall of a pair of knobs 503. After the height of the test assembly 3 is adjusted, during testing, rotating one set of knobs 503 will cause both sets of knobs 503 to rotate under the action of the steel rope 504, thereby driving the two sets of control levers 501 to rotate. The rotation of rod 501 and bidirectional threaded rod 502 causes the two sets of hollow shells 401 on the bidirectional threaded rod 502 to move to both sides, so that the threaded block 404 slides on the inner wall of the square groove 2034, and at the same time the hollow shell 401 slides on the inner wall of the slide groove 2032, so that the hollow shell 401 drives the guide block 403 into the slide groove 2032, away from the side wall of the second auxiliary block 304. At this time, the second auxiliary block 304 is not limited by the guide block 403, and under the action of the impact block 301, it quickly slides on the inner wall of the transverse groove 2031. At the same time, the impact block 301 moves downward quickly, causing an impact force on the exhaust pipe, thereby realizing the detection of the exhaust pipe's impact resistance.

[0034] In use, the height of the impact block 301 is limited by the limiting component 4 to obtain different test data. By pulling the handles 3031 and connecting rods 303 on both sides of the impact block 301, the impact block 301 is raised, avoiding the need for workers to frequently lift the impact block 301 directly, which greatly reduces the workload. By adjusting the position of the limiting component 4 by the control component 5, the impact block 301 can be dropped quickly, thereby completing the test of the exhaust pipe.

[0035] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
