Description

Technical Field

[0001] This utility model relates to the field of cement testing technology, and in particular to an auxiliary structure for a cement compressive strength tester. Background Technology

[0002] Cement is a powdery hydraulic inorganic binder that forms a paste when mixed with water. It can harden in air or water and can firmly bind materials such as sand and stone together. To ensure the use and quality of cement, workers use a cement compressive strength tester to test it. By placing a small piece of cement on a compression plate, a piston drives the test piece to compress the cement, and the compressive strength data of the cement is displayed on the controller.

[0003] Announcement No. CN220819623U proposed an auxiliary structure for a cement compressive strength tester. In the implementation of this device, a lever is manually pulled backward, causing a clamping block to move to the left and disengage from the protrusion. This allows the test piece to move downward and disengage from the piston, thus completing the disassembly of the test piece. However, since this structure has two levers, both need to be pulled simultaneously, requiring additional personnel to support the dislodged test piece to prevent it from falling directly and damaging it, thus affecting its subsequent use. Therefore, an auxiliary structure for a cement compressive strength tester is proposed to address these issues. Utility Model Content

[0004] The purpose of this utility model is to at least solve one of the technical problems existing in the prior art, and to provide an auxiliary structure for a cement compressive strength tester that can solve the problems in the background art.

[0012] Preferably, a return spring is fixedly connected inside the fixed disk, and the end of the return spring away from the fixed disk is fixedly connected to the locking rod.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] (1) The auxiliary structure for the cement compressive strength tester rotates the rotating shell so that the screw rotates and inserts into the threaded groove, thereby fixing the fixed plate and the fixed plate. This allows the operator to install and disassemble the test piece by moving the fixed rod with one hand, and adjust and support the test piece with the other hand.

[0023] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0024] Please see Figure 1-6 This utility model provides a technical solution: an auxiliary structure for a cement compressive strength tester, including a workbench 1, a base 3 fixedly connected to the surface of the workbench 1, a compressive strength plate 4 fixedly connected to the upper surface of the base 3, a piston 5 disposed at the upper end of the workbench 1, a fixing plate 10 fixedly connected to the surface of the piston 5, and a circumferentially arranged gear 11 rotatably connected to the surface of the fixing plate 10. A sliding rod 12 is slidably connected inside the gear 11, the sliding rod 12 is hexagonal in shape, and a screw 13 is fixedly connected to the surface of the sliding rod 12, the screw 13 penetrating into the fixing plate 10. Externally, the screw 13 is threadedly connected to the inside of the fixed plate 10. Through the setting of the sliding rod 12, when the gear 11 rotates, the gear 11 drives the sliding rod 12, thereby driving the screw 13 to rotate. Since the screw 13 is threadedly connected to the fixed plate 10, the screw 13 moves outward from the fixed plate 10 as it rotates, while the sliding rod 12 slides inward from the gear 11. The bottom of the piston 5 is provided with a fixed plate 7, and the bottom of the fixed plate 7 is fixedly connected to the test piece 8. The surface of the fixed plate 7 has circumferentially arranged threaded grooves 18.

[0025] A rotating shell 6 is rotatably connected to the surface of piston 5. The interior of rotating shell 6 is rotatably connected to the surface of fixed plate 10. A fixed rod 9 arranged in a circle is fixedly connected to the surface of rotating shell 6. An annular rack 16 is fixedly connected to the interior of rotating shell 6. The surface of annular rack 16 meshes with the surface of gear 11.

[0026] A positioning rod 14 is fixedly connected to the bottom of the piston 5. The positioning rod 14 is in the shape of a regular hexagon. A groove 2 is provided on the surface of the fixed plate 7. The groove 2 is also in the shape of a regular hexagon. By inserting the positioning rod 14 into the groove 2, the position of the screw 13 and the threaded groove 18 can be positioned, which makes it easier for the staff to fix the fixed plate 7 and the test piece 8.

[0027] The fixed plate 7 has a sliding connection of a locking rod 17. The two ends of the locking rod 17 pass through the threaded groove 18 and the groove 2 respectively. The end of the locking rod 17 located inside the threaded groove 18 is inclined. The surface of the positioning rod 14 is provided with a fixing groove 15.

[0028] A return spring 19 is fixedly connected inside the fixed plate 7. The end of the return spring 19 away from the fixed plate 7 is fixedly connected to the locking rod 17. The sliding of the locking rod 17 is controlled by the setting of the return spring 19.

[0029] Working principle: When it is necessary to fix the fixed plate 7 and the fixed plate 10, the operator lifts the test piece 8 and the fixed plate 7, so that the fixed plate 7 and the fixed plate 10 are in contact. At this time, the positioning rod 14 is inserted into the groove 2 as the fixed plate 7 moves upward, so that the threaded groove 18 corresponds to the position of the screw 13, so that the fixed plate 7 no longer shakes. Then the operator rotates the fixing rod 9, so the fixing rod 9 drives the rotating shell 6 to rotate. The rotating shell 6 drives the ring rack 16 to rotate, so the ring rack 16 rotates to drive the gear 11. The gear 11 rotates to drive the sliding rod 12, so the sliding rod 12 drives the screw 13 to rotate. The screw 13 rotates and moves outward of the fixed plate 10, so the screw 13 rotates and inserts into the threaded groove 18, thus completing the fixation between the fixed plate 7 and the fixed plate 10.

[0030] When the screw 13 is inserted into the threaded groove 18, the screw 13 presses against the inclined surface of the clamp 17, causing the clamp 17 to move under force. The movement of the clamp 17 causes the return spring 19 to deform, and then the clamp 17 is forced to insert into the fixed groove 15, further reinforcing the connection between the fixed plate 10 and the fixed disk 7, and further improving the fixing effect of the device.

[0031] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
