Description

Technical Field

[0001] The utility model belongs to the field of cement hardness detection, and particularly relates to a cement hardness detection device with convenient operation. Background Technique

[0002] Cement products are products made with cement as the main binding material, shaped into various finished products, such as: cement pipes, cement flower bricks, and terrazzo. Cement products need to be subjected to hardness detection before leaving the factory to understand the strength of their structures.

[0003] According to the utility model patent with the authorization announcement number CN215448830U, a hardness detection device for cement product production proposed therein includes a detection box and a cement placement box. On both sides of the lower part of the inner wall of the detection box, first clamping blocks are installed, and a placement box is fixed to the outer wall of the first clamping blocks. A driving motor is installed inside the placement box, and a rotating shaft is installed above the inner wall of the driving motor. A fixing mechanism is fixed above the outer wall of the rotating shaft, and a cement inverted placement box is arranged on the outer surface of the fixing mechanism.

[0004] However, the existing cement hardness detection device has a complex structure and inconvenient operation, and can only be used for cement products with fixed sizes, with poor applicability. Therefore, it needs to be improved. Summary of the Invention

[0005] The purpose of the utility model is to provide a cement hardness detection device with convenient operation, which solves the problems of the existing cement hardness detection device having a complex structure and inconvenient operation, and at the same time solves the problem of poor applicability for only being able to detect cement products with fixed sizes.

[0006] To achieve the above purpose, the utility model provides a cement hardness detection device with convenient operation, including a fixed sleeve. Two symmetrically distributed sliding frames are slidably connected inside the fixed sleeve. A slider is fixedly connected to the inner side of the vertical part of the sliding frame. A clamping shell is slidably sleeved outside the slider. The upper end of the horizontal part of the sliding frame is fixedly connected with a linkage piece. The linkage piece penetrates the fixed sleeve and is slidably connected with the fixed sleeve. A bidirectional screw is threadedly connected inside the linkage piece. A support is fixedly connected to the bottom of the fixed sleeve. An adjusting rod is threadedly connected inside the support. The lower end of the adjusting rod is installed with a bearing on a bottom plate, and a plurality of cutting knives are fixedly connected to the bottom of the bottom plate.

[0007] The principle of this utility model is as follows: When in use, the whole is placed at the cement board to be detected, and the sliding frames are located on both sides of the cement board. Then, the two-way screw is rotated through the knob, and the linkage pieces move horizontally through the relative threaded movement with the two-way screw. Subsequently, the linkage pieces drive their respective corresponding sliding frames to slide until the clamping shells clamp on both sides of the cement board. Then, the adjusting rod is rotated through the turning knob, and the adjusting rod moves downward through the relative threaded movement with the bracket. Subsequently, the bottom plate at the bottom of the adjusting rod drives the cutting knife to move downward until the cutting knife touches the cement board. Then, the fixed sleeve is pushed, and the fixed sleeve drives components such as the sliding frame and the cutting knife to slide relative to the clamping shell, so that the cutting knife scratches on the surface of the cement board. The staff can conduct simple hardness detection based on the degree of scratching, and by controlling the position of the cutting knife, the pressure of the cutting knife on the cement board can be adjusted.

[0008] The beneficial effects of this utility model are as follows: By arranging a fixed sleeve, a bracket is arranged below the fixed sleeve, an adjusting rod that moves relative to the bracket in a threaded manner is arranged inside the bracket, a bottom plate that is guided to move up and down through a guide rod is arranged at the end of the adjusting rod, and a cutting knife is arranged at the bottom of the bottom plate. In this way, by controlling the different height positions of the cutting knife, the hardness of the cement board under different pressures can be detected, and the operation is simple and convenient.

[0009] Sliding frames that can be adjusted and slid are arranged on both sides of the fixed sleeve, and a combination of a slider that can slide relative to the inside and a clamping shell is arranged on the inner side of the sliding frame. In this way, by utilizing the relative threaded movement between the two-way screw and the linkage piece, the distance between the sliding frames can be controlled, so that the whole can clamp cement boards of different widths, increasing the applicability.

[0010] Further, a limiting rod is fixedly connected to the inner side of the clamping shell, and the limiting rod penetrates through the slider and is slidably connected to the slider. Through the arrangement of the limiting rod, it has a guiding and limiting effect on the relative sliding of the slider inside the clamping shell.

[0011] Further, balls are arranged inside the slider, and the balls are slidably connected to the inner surface of the clamping shell. Through the arrangement of the balls, the relative friction between the slider and the clamping shell can be reduced.

[0012] Further, a knob is fixedly connected to the middle section of the rod body of the two-way screw, and the knob is made of plastic. Through the arrangement of the knob, it is convenient to rotate the two-way screw.

[0013] Further, a fixing plate is fixedly connected to the upper edge of the fixed sleeve, and the fixing plate is connected to the two-way screw through a bearing. Through the arrangement of the fixing plate, it has a supporting effect on the two-way screw.

[0014] Further, a turning knob is fixedly connected to the top of the adjusting rod, and the turning knob is made of plastic. Through the arrangement of the turning knob, it is convenient to rotate the adjusting rod.

[0015] Further, a guide rod is fixedly connected to the upper end of the bottom plate, and the guide rod penetrates through the bracket and is slidably connected to the bracket. Through the arrangement of the guide rod, it has a guiding effect on the lifting adjustment of the cutting knife. BRIEF DESCRIPTION OF THE DRAWINGS
