Description

Technical Field

[0001] This utility model relates to the field of concrete impermeability testing technology, and more specifically, it relates to an impermeability tester for concrete impermeability testing. Background Technology

[0002] In practical applications of concrete impermeability testing, it is necessary to frequently change and fix the test container according to different specifications of concrete specimens and testing requirements to ensure the sealing and accuracy of the testing process. Traditional concrete impermeability testing equipment mostly uses threaded connection or mechanical clamping to install and fix the test container. However, these fixing methods are complicated to operate and have low installation efficiency. They often cannot meet the requirements of rapid installation when facing batch testing of specimens or changing containers of different specifications.

[0003] The existing fixing method requires operators to use special tools to tighten or adjust multiple fixing points one by one, which is not only time-consuming but also prone to uneven fixing or poor sealing. It cannot meet the requirements of high efficiency and standardized operation in modern building materials testing laboratories, and seriously affects the continuity and accuracy of impermeability testing. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] In view of the problems existing in the prior art, this utility model provides a permeability tester for concrete permeability testing, so as to solve the technical problems mentioned in the background art.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a permeability tester for concrete permeability testing, comprising a testing platform, on which a mold base is mounted, the mold base being provided in multiple sets and each having an installation mechanism at its top, the installation mechanism comprising an installation sleeve and a locking block, the installation sleeve being fixed to the inner side of the mold base and having a sliding groove on its outer wall, the sliding groove being provided in multiple sets, the locking block being provided in multiple sets and sliding within the multiple sets of locking blocks, a mold sleeve being inserted into the installation sleeve, the mold sleeve having a locking groove on its outer wall, the locking groove being provided in multiple sets and abutting against the multiple sets of locking blocks, a control sleeve being provided on the outer side of the multiple sets of locking blocks, a rotating sleeve being rotatably provided on the outer side of the installation sleeve, and a push block being fixed on the bottom surface of the rotating sleeve, the push block being provided in multiple sets.

[0008] The present invention is further configured such that a limiting rod is fixedly provided on the outside of the control sleeve, and the limiting rod is provided in multiple sets and abuts against the outside of multiple sets of locking blocks respectively, thereby radially restricting the locking blocks to ensure accurate movement trajectory of the locking blocks and prevent position deviation.

[0009] The present invention is further configured such that each of the multiple sets of limiting rods has a variable diameter groove on its inner side, and the multiple sets of variable diameter grooves are slidably connected to multiple sets of locking blocks, guiding the locking blocks to realize the locking and disengaging actions to ensure a smooth switch between the locking and disengaging states.

[0010] The present invention is further configured such that a sealing gasket is provided inside the mounting sleeve, and the test mold sleeve abuts against the top surface of the sealing gasket, thereby forming an effective sealing interface through compression to prevent water leakage during the impermeability test.

[0011] The present invention is further configured such that the outer sides of the multiple sets of push blocks are all arc-shaped, which reduces stress concentration, provides uniform pushing force distribution, ensures uniform force on the block, and improves transmission efficiency.

[0012] The present invention is further configured such that a positioning sleeve is fixedly provided on the top surface of the rotating sleeve, a movable groove is provided on the inner side of the positioning sleeve, and multiple sets of positioning blocks are provided in the movable groove and are slidably connected to each other. A push spring is provided between the top of each set of positioning blocks and the sliding hole. A positioning groove is provided on the outer wall of the mounting sleeve, and multiple sets of positioning grooves are provided and abut against each other, thereby realizing precise positioning of the rotating sleeve, preventing accidental rotation, and ensuring stable and reliable positioning.

[0013] The present invention is further configured such that a sliding rod is fixedly provided on the outside of the control sleeve, and multiple sets of sliding rods are provided; a sliding hole is provided inside the rotating sleeve, and multiple sets of sliding holes are provided and are slidably connected to multiple sets of sliding rods respectively, so as to realize synchronous movement between the two sleeves and ensure accurate transmission of the control of the locking block.

[0014] The present invention is further provided that a return spring is provided between the rotating sleeve and the control sleeve. The return spring is provided in multiple sets and is respectively provided on the outside of multiple sets of slide rods, so that the control sleeve automatically returns to the initial position and drives the card block to disengage from the card slot to prepare for the next operation.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, this utility model provides a permeability tester for concrete permeability testing, which has the following beneficial effects:

[0017] 1. By precisely sliding multiple sets of locking blocks within the groove and achieving uniform multi-point contact fixation, and with the linkage mechanism of the rotating sleeve and push block working in conjunction with the control of the positioning sleeve and positioning block, operators only need to perform a simple rotation of the rotating sleeve to complete the synchronous fixation of all locking points. This changes the cumbersome operation method of traditional impermeability testing equipment, which requires tightening threads one by one or adjusting multiple clamping devices, significantly improving the installation efficiency and fixation reliability of the test container, and meeting the high-efficiency requirements of modern building materials testing laboratories for frequent container replacement and standardized operations.

[0018] 2. By rotating the rotating sleeve, the push block is released from its contact with the locking block, thus releasing the clamping of the test container. The return spring automatically pulls the control sleeve, causing the locking block to slide along the sliding hole. The linkage between the sliding rod and the control sleeve causes the locking block to rotate into the variable diameter groove, and the variable diameter groove pulls the locking block out of the slot. The entire unlocking process does not require the operator to loosen each fixed point one by one, which solves the problem of the long time required for manual loosening of threads and manual release of clamping devices in traditional impermeability testing equipment. It is especially suitable for frequent container replacement in high-intensity laboratory working environments, greatly improving the operational efficiency of equipment maintenance and test container replacement.

[0019] 3. This device incorporates multiple safety safeguards and precise positioning mechanisms. The push spring provides continuous positioning pressure to the positioning block to ensure the precise positioning of the rotating sleeve and prevent misoperation. The reset spring provides elastic reset force to the control sleeve to ensure the automatic reset of the system. The precise fit between the variable diameter groove and the locking block enables reliable control of locking and disengagement. The tight contact between the sealing gasket and the test mold sleeve ensures the sealing performance during the testing process. Attached Figure Description

[0037] In this embodiment, when the test mold sleeve 6 needs to be installed, the test block is first installed inside the test mold sleeve 6. Then, the test mold sleeve 6 is inserted into the installation sleeve 3 and abuts against the top surface of the sealing gasket 13. The rotating sleeve 9 is rotated to drive the positioning sleeve 14 to rotate. Multiple positioning slots 18 push multiple positioning blocks 16 out of the positioning slots 18 and squeeze the push spring 17, so that the multiple positioning blocks 16 move in the multiple positioning slots 18. Multiple sliding rods 19 drive the control sleeve 8 to rotate, so that multiple locking blocks 4 slide out of the diameter-changing groove 12 and are pushed into the locking groove 7 by the limiting rod 11.

The multiple sets of variable diameter grooves 12 pull the locking blocks 4 to disengage them from the locking groove 7, releasing the locking of the test mold sleeve 6. Then the test mold sleeve 6 can be pulled out of the mounting sleeve 3 to complete the disassembly.

[0039] In summary, when the entire equipment is in use or operation: when it is necessary to install the test mold sleeve 6, first install the test block inside the test mold sleeve 6, then insert the test mold sleeve 6 into the installation sleeve 3 and abut against the top surface of the sealing gasket 13.

At the same time, through multiple sets of push blocks 10, push the locking blocks 4 to slide along the sliding groove 5 and drive the test mold sleeve 6 to squeeze the sealing gasket 13. Then stop rotating the rotating sleeve 9, and through multiple sets of push springs 17, push the positioning blocks 16 to abut against the positioning grooves 18 to position the rotating sleeve 9, thereby completing the installation of the test mold sleeve 6.

[0040] When it is necessary to disassemble the test mold sleeve 6, rotate the rotating sleeve 9 to release the multiple sets of push blocks 10 from abutting the locking blocks 4. The multiple sets of reset springs 21 pull the control sleeve 8 and drive the multiple sets of locking blocks 4 to slide along the sliding hole 20.

The multiple sets of variable diameter grooves 12 pull the locking blocks 4 to disengage them from the locking groove 7, releasing the locking of the test mold sleeve 6. Then the test mold sleeve 6 can be pulled out of the mounting sleeve 3 to complete the disassembly.
