[0002] In home decoration, a common decoration structure of windows is that the window frame is often formed by splicing and fixing multiple plastic profiles. After the mass production of profiles is completed, it is usually necessary to randomly inspect some profiles to test their brittleness to ensure their factory quality.

[0003] The traditional inspection method is to cut a section of the profile and place it horizontally on the ground so that the top of the profile presents an inverted V shape. Figure 1 As shown. Then the staff stepped on the top of the profile with their feet. If the profile is not damaged, it means that its brittleness is qualified. However, different staff have different weights and different stepping forces during inspection. Therefore, this manual inspection method has the problem of large errors. Utility Model Content

DETAILED DESCRIPTION

[0019] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0020] The present application embodiment discloses a profile brittleness inspection tool, referring to Figure 2 , Figure 3 and Figure 4 , comprising a base 1, on which two positioning plates 2 are arranged at intervals, and a positioning groove 21 for accommodating the bottom of the profile 10 is formed between the two positioning plates 2. A mounting frame 3 is bolted to the base 1 above the positioning groove 21, and a drop hammer 4 for hitting the profile 10 is vertically slidably arranged on the mounting frame 3, and a V-shaped groove 41 for abutting the top of the profile 10 is formed at the bottom of the drop hammer 4, and a first driving member for driving the drop hammer 4 to move is installed on the mounting frame 3.

[0021] In the embodiment of the present application, the staff cuts off a section of the profile 10 to be inspected, places it in the installation slot, and then starts the first driving member to drive the drop hammer 4 to hit the top of the profile 10. In this way, each section of the profile 10 is hit by the drop hammer 4 with the same force, which reduces the error of the inspection result. Compared with the traditional inspection method, it has the effect of improving the accuracy of the inspection result.

[0022] Specifically, the first driving member includes a pull rope 5 movably overlapped on the top of the mounting frame 3, one end of the pull rope 5 is connected to the drop weight 4, and the other end of the pull rope 5 is provided with a handle 51, and the handle 51 hangs down on the outside of the mounting frame 3.

[0023] The staff can pull the pull rope 5 by holding the handle 51, and pull the drop hammer 4 to the top wall of the mounting frame 3, and then release the pull rope 5, and the drop hammer 4 will fall down by itself to hit the top of the profile 10. During each inspection, the drop height of the drop hammer 4 is the same, so that the top of the profile 10 of the same model and size is hit with the same force.

[0024] Furthermore, a guide member 6 is connected between the mounting frame 3 and the drop weight 4, and the guide member 6 includes a guide cylinder 61 and a slide rod 62. The guide cylinder 61 is vertically welded and fixed on the mounting frame 3, and the slide rod 62 is slidably connected in the guide cylinder 61. One end of the slide rod 62 is bolted to the drop weight 4, and the other end of the slide rod 62 is welded with a pull ring, and the pull rope 5 is connected to the pull ring.

[0025] In the embodiment of the present application, the slide bar 62 can only move axially along the guide cylinder 61, which improves the stability of the drop hammer 4 when it falls and hits the profile 10. A fixing plate 31 is bolted to one side of the mounting frame 3, and a notch is provided on the fixing plate 31. When there is only one worker on site, the worker can pull up the drop hammer 4 and insert the handle 51 into the notch, so that the drop hammer 4 can be suspended in the air and the profile 10 in the positioning groove 21 can be replaced. The suspension height of the drop hammer 4 should not be set too high, so as to reduce the safety hazard of the worker when replacing the profile 10.

[0026] Furthermore, the two positioning plates 2 are arranged on the base 1 for horizontal sliding in opposite directions along their width direction, and the base 1 is provided with a limiter 7 for limiting the movement of the positioning plates 2, and the limiter 7 includes a plurality of limiter bolts 71. The positioning plates 2 are provided with a plurality of parallel strip holes 22 along their own moving direction, and the base 1 is provided with threaded holes with sizes matching the limiter bolts 71 below the strip holes 22, and the plurality of limiter bolts 71 are threadedly connected in the threaded holes after passing through the corresponding strip holes 22 one by one.

[0027] In the embodiment of the present application, the bottom widths of profiles 10 of different models and sizes are also different. The width of the positioning groove 21 can be adjusted by loosening the adjusting bolt so that it can adapt to profiles 10 of various models and sizes. After the adjustment is completed, tighten the adjusting bolt to fix the positioning plate 2.

[0028] Furthermore, two clamping plates 8 are provided on the base 1 at both ends of the positioning plate 2 for sliding in opposite directions along the length direction of the profile 10, and a second driving member for driving the clamping plates 8 to move is installed on the base 1, and the second driving member includes a bidirectional screw 9. On the base 1, along the length direction of the profile 10, a slide groove 11 for the clamping plates 8 to slide is provided at both ends of the positioning plate 2, and the bidirectional screw 9 is horizontally rotatably provided on the base 1, and the two threaded sections of the bidirectional screw 9 are respectively located in the corresponding slide groove 11. Screw nuts are welded and fixed at the bottom of the two clamping plates 8, and the two screw nuts are respectively threadedly connected to the corresponding threaded sections.

[0029] In the embodiment of the present application, both ends of the profile 10 extend beyond the positioning plate 2, and rotating the bidirectional screw 9 can drive the two clamping plates 8 to slide synchronously in opposite directions, so that they can jointly clamp the profile 10 in the positioning groove 21, further improving the stability of the profile 10 during the inspection process.

[0030] Reference Figure 5 The side of the clamping plate 8 that is used to contact the profile 10 is bonded with an anti-skid pad 81. The anti-skid pad 81 can be made of rubber and can increase the friction force on the end of the profile 10. The side of the anti-skid pad 81 that is used to contact the profile 10 is integrally fixed with a plurality of protrusions, which can further improve the fixing effect of the clamping plate 8 on the profile 10.

[0031] The implementation principle of the profile brittleness inspection tool of the embodiment of the present application is as follows: the staff cuts a section of the profile 10 to be inspected, places it in the installation slot, then pulls the pull rope 5 and pulls the drop hammer 4 to the top wall of the mounting frame 3, loosens the pull rope 5, and the drop hammer 4 falls down by itself to hit the top of the profile 10. In this way, the profiles 10 of the same model and size are hit by the drop hammer 4 with the same force, which reduces the error of the inspection result. Compared with the traditional inspection method, it has the effect of improving the accuracy of the inspection result.
