[0020] The following elaborates on the preferred embodiments of the present utility model in conjunction with the attached drawings, so that the advantages and features of the present utility model can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present utility model. The directional terms mentioned in the present utility model, such as "upper", "lower", "front", "rear", "left", "right", "top", "bottom", etc., are only references to the directions in the attached drawings. Therefore, the directional terms used are for explaining and understanding the present utility model, rather than for limiting the present utility model.
[0021] As Figures 1-4 shown, a plate compressive strength detection device includes a pressure detection table 10, a hydraulic lifting column 20 is established on the pressure detection table 10, a lifting arm 21 is vertically lifted and driven inside the hydraulic lifting column 20, the lifting arm 21 is perpendicular to the hydraulic lifting column 20, and a punching rod 30 is installed at the bottom end surface of the lifting arm 21;
[0022] The stamping rod 30 includes an inner rod core 301 and an outer rod sleeve 302. On the outer end face of the inner rod core 301, clamping grooves 32 are symmetrically arranged. On the inner wall of the outer rod sleeve 302, limiting sliders 33 are arranged corresponding to the clamping grooves 32. When the outer rod sleeve 302 is sleeved on the outside of the inner rod core 301, the limiting sliders 33 are slidably clamped in the clamping grooves 32.
[0023] At the bottom end of the lifting arm 21, multiple groups of mounting openings 22 are arranged, and at the top end of the stamping rod 30, a threaded column 31 is arranged. The threaded column 31 and the mounting opening 22 are fixedly connected by screwing.
[0024] The clamping groove 32 includes a vertical groove and multiple arc grooves communicating with the vertical groove. The bottom end of the vertical groove is open, and the outer rod sleeve 302 is provided with corresponding numbers of limiting sliders 33 corresponding to the multiple arc grooves. The limiting sliders 33 are fixed to the inner wall of the outer rod sleeve 302 through fixing rods 34, and the limiting sliders 33 are slidably limited in the vertical groove and the arc grooves.
[0025] On the outer end face of the outer rod sleeve 302, clamping grooves 32 are also arranged. The clamping grooves 32 of the outer rod sleeve 302 are used to connect rod sleeves with a larger diameter.
[0026] In this embodiment, when performing the plate compressive strength test, the position of the stamping rod 30 can be selected and the size of the stamping rod 30 can be adjusted according to the test requirements, so as to better meet the test needs. Other accessories and instruments for the plate compressive strength test are all prior arts and are not the main technical content of this application, so they will not be described.
[0027] When selecting the position of the stamping rod 30, the threaded column 31 at the top end of the stamping rod 30 can be screwed tightly with the mounting opening 22 on the bottom end face of the lifting arm 21. According to the requirements, the stamping rod 30 can be installed at different mounting openings 22.
[0028] When adjusting the size of the stamping rod 30, a rod sleeve can be added to the outside of the existing inner rod core 301. Among them, by adding an outer rod sleeve 302 to the clamping groove 32 of the inner rod core 301 to increase the diameter of the stamping rod 30, the size adjustment of the stamping rod 30 can be realized.
[0029] Among them, by inserting the limiting slider 33 on the outer rod sleeve 302 into the vertical groove of the clamping groove 32 from the bottom end of the clamping groove 32, and then rotating the outer rod sleeve 302, the limiting slider 33 enters the arc groove, so that the outer rod sleeve 302 is sleeved and fixed on the inner rod core 301. At this time, the size of the stamping rod 30 sleeved with the outer rod sleeve 302 becomes larger.
[0030] At the same time, a rod sleeve can be continuously added to the outside of the outer rod sleeve 302, and it can also be removed according to the requirements.
[0031] It should be noted that the parts not involved in the present utility model are the same as or can be implemented by the prior art; various drives in the present utility model can be implemented by corresponding power structures such as air cylinders, oil cylinders, electric cylinders, motors, etc. in cooperation with connecting rods, guide rods, etc., and are not limited to the descriptions in the specification and the structures in the drawings.

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.
[0033] The above embodiments only represent several implementation manners of the present utility model, and the descriptions are relatively specific and detailed, but should not be construed as a limitation on the scope of the utility model patent.
