[0022] The technical solution of the present invention will be clearly and completely described below through specific implementation methods.

[0023] Example 1

[0024] like Figure 1 、 Figure 2 and Figure 4 As shown, a rock mechanical properties tester includes a tester body 1, and two upper and lower parallel test frames 11 are provided inside the tester body 1. Support frame 2 5 and support frame 1 4 are fixedly installed on one side of the two test frames 11, respectively. U-shaped plates 22 are movably inserted in support frame 2 5 and support frame 1 4. Specifically, inner grooves 21 are provided on the sides of the two U-shaped plates 22 away from the test frames 11, and threaded rods 23 are passed through support frame 2 5 and support frame 1 4 corresponding to the inner grooves 21. The threaded rods 23 fix the U-shaped plates 22 by tightening the inner grooves 21.

[0025] A partition 6 and a limit plate 7 are connected to the side of the U-shaped plate 22 away from the inner groove 21. The partitions 6 on the two U-shaped plates 22 located in the support frame 2 5 and the support frame 1 4 are close to each other. The partition 6 is used to place rocks, and the limit plate 7 is used to prevent the U-shaped plate 22 from falling off from the support frame 2 5 and the support frame 1 4.

[0026] When the tester body 1 is testing a rock, the rock is placed between the two partitions 6. Before starting the tester body 1, the user can adjust the U-shaped plate 22 inside the support frame 2 5 and the support frame 1 4. The user rotates the threaded rod 23. Both threaded rods 23 rotate inside the support frame 2 5 and the support frame 1 4 through the thread, while moving away from the inner groove 21. At this time, the user can adjust the height of the two U-shaped plates 22. After the adjustment is completed, the ends of the threaded rods 23 are rotated to fit tightly against the inner groove 21. During the rock testing process, the two U-shaped plates 22 can shield one side of the test frame 11. When the rock is broken, the two U-shaped plates 22 can block it and play a protective role.

[0027] Example 2

[0028] like Figure 1 、 Figure 2 and Figure 3 As shown, based on Example 1, an extension plate 25 is installed on the opposing surfaces of the two U-shaped plates 22. Specifically, L-shaped grooves 24 are formed on the opposing surfaces of the two U-shaped plates 22, and magnetic plates 26 are provided on the end surfaces of the two extension plates 25. The magnetic plates 26 can be inserted into the L-shaped grooves 24 and magnetically attracted to the inner walls of the L-shaped grooves 24, thereby completing the installation of the extension plate 25 and the U-shaped plates 22.

[0029] In the present application, the opposite sides of the two expansion boards 25 are also installed with expansion board 3 31 and expansion board 2 28 respectively. Specifically, expansion board 1 25 is connected to expansion board 2 28 and expansion board 3 31 through springs 210 (micro springs can be optionally used) and inner plug-in board 27. When the springs 210 are compressed, the inner plug-in board 27 can be inserted into the expansion board 1 25.

[0030] Preferably, the end of the expansion board 31 is connected to the lower plug board 32, and the end of the expansion board 28 forms a slot 29, and the lower plug board 32 can be inserted into the slot 29. The expansion board 28 and the expansion board 31 on the opposite sides of the two expansion boards 1 25 of the utility model increase the protection range of the two U-shaped boards 22.

[0031] During use, when the distance between the two test racks 11 is large, the user can connect the two extension plates 1 25 to the two U-shaped plates 22, that is, insert the magnetic plates 26 at the ends of the two extension plates 1 25 into the two L-shaped grooves 24. When the two test racks 11 are close to each other, the extension plate 3 31 and the extension plate 2 28 will squeeze each other. At this time, the springs 210 between the two extension plates 1 25 and the extension plates 2 28 and 31 are compressed and deformed, and the two inner insert plates 27 move into the extension plate 1 25. By combining the extension plate 1 25 with the U-shaped plate 22, the present utility model effectively increases the protection range of the U-shaped plate 22 to cope with protection at different distances, greatly improving the practicality of the device.

[0032] The embodiments described above are merely preferred embodiments of the present invention and are not intended to limit the concept and scope of the present invention. Without departing from the design concept of the present invention, various modifications and improvements to the technical solutions of the present invention made by ordinary engineering technicians in this field should fall within the scope of protection of the present invention. The technical contents requested for protection of the present invention have been fully recorded in the technical requirements.
