Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-5 One embodiment provided by this utility model:

[0025] A device for testing the compressive strength of recycled concrete samples includes:

[0026] The machine body includes a support platform 1 and a telescopic cylinder 12. A support frame 11 is fixedly connected to the surface of the support platform 1. The output shaft of the telescopic cylinder 12 is connected to a pressure plate 13. With the connection between the support platform 1 and the support frame 11, the working position of the telescopic cylinder 12 is supported. Through the connection between the telescopic cylinder 12 and the pressure plate 13, the working position of the pressure plate 13 on the support platform 1 is adjusted.

[0027] The support mechanism includes a connecting frame 2, which is fixedly connected to the upper surface of the support platform 1. The surface of the support platform 1 is provided with an adjustment groove 21, and the surface of the connecting frame 2 is provided with a sliding groove 22. An adjustment rod 23 is connected through the sliding groove 22. A movable block 24 is fixedly connected to the bottom end of the adjustment rod 23. A hinge rod 25 and a movable rod 26 are movably connected to the bottom end of the movable block 24. A stop rod 27 is movably connected to the surface of the movable rod 26. A limit plate 28 is fixedly connected to the bottom end of the stop rod 27. A stop plate 29 is fixedly connected to the surface of the limit plate 28. A support spring 210 is fixedly connected to the bottom end of the stop plate 29. Through the connection between the connecting frame 2 and the sliding groove 22, and under the sliding connection between the sliding groove 22 and the adjustment rod 23, the change in the working height of the movable block 24 achieves the effect of adjusting the working angle of the hinge rod 25 and the movable rod 26, thereby changing the working position of the stop rod 27 in the adjustment groove 21.

[0028] Furthermore, the connecting frame 2 is L-shaped, and the connecting frame 2 is evenly distributed in three groups on the surface of the support platform 1. The adjusting groove 21 is also in three groups and is correspondingly opened on the surface of the support platform 1. The adjusting rod 23 is slidably connected to the connecting frame 2 through the sliding groove 22. Through the connection between the adjusting rod 23 and the sliding groove 22, the position of the adjusting rod 23 on the connecting frame 2 can be changed under the action of the sliding groove 22, so as to prevent the adjusting rod 23 from affecting the movement trajectory of the movable block 24 and the movable rod 26.

[0029] Furthermore, the outer surface of the adjusting rod 23 is threaded with two sets of threaded rings, and the two sets of threaded rings are distributed on the upper and lower surfaces of the connecting frame 2. The movable block 24 is block-shaped. Through the connection between the adjusting rod 23 and the movable block 24, the angle of action of the hinge rod 25 and the movable rod 26 can be adjusted under the action of the movable block 24.

[0030] Furthermore, the two ends of the hinge rod 25 are movably connected to the surface of the movable block 24 and the inner side of the adjustment groove 21, respectively. The two ends of the movable rod 26 are movably connected to the surfaces of the movable block 24 and the abutment rod 27. The abutment rod 27 is slidably connected to the support platform 1 through the adjustment groove 21. Through the connection of the movable rod 26 and the abutment rod 27, the position of the abutment rod 27 in the adjustment groove 21 can be changed by changing the angle of action of the movable rod 26, thereby improving the application range and performance of the abutment rod 27.

[0031] Furthermore, the limiting plate 28 acts as a plate inside the adjusting groove 21, and the abutment plate 29 acts in two sets at both ends of the limiting plate 28. The two ends of the support spring 210 are fixedly connected to the surfaces of the abutment plate 29 and the limiting plate 28. Through the connection between the limiting plate 28 and the abutment rod 27, under the action of the limiting plate 28 and the abutment plate 29, the abutment plate 29 and the inner side of the adjusting groove 21 abut against each other, achieving the abutment support effect of the abutment rod 27 in the adjusting groove 21, and making it less likely for the abutment rod 27 to slide freely in the adjusting groove 21.

[0032] Furthermore, a connecting mechanism is provided on the outer surface of the telescopic cylinder 12. The connecting mechanism includes a fixed frame 3, which acts on the outer surface of the telescopic cylinder 12. A rotating handle 31 is movably connected to the surface of the fixed frame 3, and a clamping plate 32 is fixedly connected to the bottom end of the rotating handle 31. A slot 33 is opened on the surface of the pressure plate 13. Through the connection between the telescopic cylinder 12 and the fixed frame 3, the fixed frame 3 is evenly distributed in three groups on the surface of the telescopic cylinder 12, which improves the stability of the connection between the telescopic cylinder 12 and the pressure plate 13.

[0033] Furthermore, both the fixing frame 3 and the clamping plate 32 are L-shaped. The fixing frame 3 and the clamping plate 32 are movably connected by the rotating handle 31. The cross-section of the clamping groove 33 is L-shaped. The clamping plate 32 is connected to the pressure plate 13 by the clamping groove 33. With the connection between the rotating handle 31 and the clamping plate 32, the clamping plate 32 and the clamping groove 33 are connected by insertion, achieving the effect of quick assembly and disassembly between the telescopic cylinder 12 and the pressure plate 13.

[0034] Working principle: When placing the sample, the position of the adjusting rod 23 on the connecting frame 2 is changed, which changes the working height of the movable block 24. At this time, the working angle of the hinge rod 25 and the movable rod 26 changes, and the position of the abutment rod 27 changes under the action of the movable rod 26. Through the action of the abutment rod 27, the abutment support effect of placing the sample on the support platform 1 can be achieved. Under the action of the abutment plate 29 and the support spring 210, the abutment rod 27 can be prevented from sliding freely in the adjusting groove 21.

[0035] When disassembling and assembling the pressure plate 13, the connection between the fixed frame 3 and the rotating handle 31, and the connection between the rotating handle 31 and the clamping plate 32, causes the angle of the clamping plate 32 to change within the clamping groove 33, thereby achieving the connection or separation effect of the pressure plate 13, and thus realizing the effect of quick disassembly and assembly of the pressure plate 13 on the telescopic cylinder 12.

[0036] 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. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
