Description

Technical Field

[0001] This utility model relates to the technical field of concrete permeability testing instruments, specifically a disassembly and assembly structure for a concrete permeability testing instrument mold. Background Technology

[0002] Concrete is widely used in construction projects as a building material. Because buildings have high requirements for the impermeability of concrete, the impermeability of concrete specimens is tested by random sampling. The concrete impermeability tester on the market is an instrument for testing the impermeability of concrete specimens. It uses a water pump to pressurize the system, and the water pressure is indicated and controlled by a pressure gauge and an electrical controller to achieve bottom-up penetration into the concrete specimen pressed in the mold, thereby measuring the impermeability of the concrete specimen.

[0003] CN219190608U discloses a disassembly and assembly structure for a concrete permeability meter mold. By setting up a first clamping sleeve, an extrusion block, a nut, and a round rod, in use, the mold body containing the concrete sample is placed on top of the mold base. Moving the first and second clamping sleeves causes the extrusion block to press against the mold body. The first and second clamping sleeves move along the surface of the round rod, and the nut is tightened onto the rod, causing the inclined surface of the extrusion block to press against the inclined surface of the mold body, thus fixing the mold body to the mold base. Disassembly simply requires unscrewing the nut from the rod, then moving the first and second clamping sleeves in the opposite direction to separate the extrusion block from the mold body. The cooperation between the first clamping sleeve, extrusion block, nut, and round rod allows only two nuts to be used to fix the same mold body position, and disassembly also requires only removing two nuts, eliminating the need to disassemble multiple nuts. This simplifies operation and achieves a more convenient disassembly and assembly effect. However, this patent still has the following problems in actual use:

[0004] Although the concrete permeability tester mold assembly and disassembly structure utilizes the cooperation between the first ferrule, the extrusion block, the nut, and the round rod to allow only two nuts to be used to fix the same mold body position, the nuts are prone to stripping after frequent use, which leads to gaps between the mold and the mold base and reduces the stability of the device.

[0005] A disassembly and assembly structure for concrete permeability test molds is proposed to address the problems mentioned above. Utility Model Content

[0006] The purpose of this utility model is to provide a disassembly and assembly structure for a concrete permeability meter mold, in order to solve the problem mentioned in the background art that currently, the cooperation between the first sleeve, the extrusion block, the nut and the round rod allows only two nuts to be used to fix the same mold body position. However, after frequent use, the nuts are prone to stripping, which leads to gaps between the mold and the mold base and reduces the stability of the device.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a disassembly and assembly structure for a concrete permeability test mold, including a self-locking mechanism and a spring column installed inside the self-locking mechanism;

[0008] Also includes:

[0009] The self-locking mechanism includes a testing platform, and a number of bottom molds are fixedly connected to the top of the testing platform. The number of bottom molds is six, and the bottom molds are evenly distributed on the top of the testing platform.

[0010] The bottom mold is attached to the top side of the test mold body. The bottom end of the test mold body has a number of through holes, six in total, and the through holes are evenly distributed inside the bottom end of the test mold body.

[0011] The through hole has a sliding connection to a limit block, and a push rod is fixedly connected to the center of the limit block.

[0012] Preferably, one end of the push rod is fixedly connected to a pull ring, and the end of the push rod away from the pull ring is fixedly connected to a cylinder, with a ring sleeved on the outer side of the cylinder.

[0013] Preferably, a hemisphere is fixedly connected to the end of the cylinder away from the push rod, and an annular groove is formed on the side of the hemisphere near the cylinder.

[0014] Preferably, the interior of the annular groove is fitted and connected to the pull ring.

[0015] Preferably, the bottom mold has a groove near the hemisphere, the inside of the groove is slidably connected to the hemisphere, and the bottom mold has symmetrical limit grooves on both sides near the groove.

[0016] Preferably, one end of the limiting groove is fixedly connected to the spring column, and one end of the spring column is fixedly connected to a stop block.

[0017] Preferably, the end of the stop block away from the spring post is fitted and connected to the hemisphere.

[0018] Compared with the prior art, the beneficial effects of this utility model are: the disassembly and assembly structure for the concrete permeability test mold, by setting a self-locking mechanism, can quickly fix the test mold body on the surface of the bottom mold, which facilitates the replacement of concrete. The specific details are as follows:

[0019] By setting a self-locking mechanism, the test mold body can be quickly fixed on the surface of the bottom mold, which facilitates the replacement of concrete. By pressing the push rod inward, the hemisphere and the ring move in the groove, while the ring slides on the surface of the cylinder. When the hemisphere and the ring coincide, the stop block can be released from limiting the hemisphere, so that the hemisphere can be moved out of the groove, thus realizing the quick disassembly of the test mold body.

[0026] Please see Figures 1-4 The present invention provides a technical solution: a disassembly and assembly structure for a concrete permeability test mold, including a self-locking mechanism 1 and a spring column 114 installed inside the self-locking mechanism 1; the self-locking mechanism 1 includes a testing platform 101, and a number of bottom molds 102 are fixedly connected to the top of the testing platform 101. There are six bottom molds 102, and the bottom molds 102 are evenly distributed on the top of the testing platform 101. A rubber ring is provided between the bottom molds 102 and the test mold body 103 to improve the sealing between them;

[0027] The bottom mold 102 is fitted to the top side of the test mold body 103. The bottom end of the test mold body 103 has a number of through holes 104. There are six through holes 104, and the through holes 104 are evenly distributed inside the bottom end of the test mold body 103. The inside of the through holes 104 is slidably connected to a limit block 105. A push rod 106 is fixedly connected to the center position inside the limit block 105. By setting the limit block 105, the push rod 106 can be prevented from falling off.

[0028] One end of the push rod 106 is fixedly connected to a pull ring 107, and the end of the push rod 106 away from the pull ring 107 is fixedly connected to a cylinder 108. A ring 109 is sleeved on the outside of the cylinder 108, and a hemisphere 110 is fixedly connected to the end of the cylinder 108 away from the push rod 106. A ring groove 111 is opened on the side of the hemisphere 110 near the cylinder 108.

[0029] The inside of the annular groove 111 is fitted and connected to the pull ring 107. By setting the annular groove 111, the circular ring 109 can be made to coincide with the hemisphere 110.

[0030] A groove 112 is provided near the hemisphere 110 on the bottom mold 102. The interior of the groove 112 is slidably connected to the hemisphere 110.

The position of the stop block 115 can be changed by setting the spring post 114.

[0031] Working principle: Before using the demolding structure for this type of concrete permeability tester, it is necessary to check the overall condition of the device to ensure it can operate normally. Figure 1 - Figure 4 As shown, first, concrete is placed inside the test mold body 103, and then it is placed on the surface of the corresponding bottom mold 102. Then, the hemisphere 110 is inserted into the groove 112. By utilizing the cooperation between the hemisphere 110 and the stop block 115, the installation of the test mold body 103 can be completed.

[0032] Secondly, when it is necessary to disassemble the test mold body 103, first press the push rod 106 inward to drive the hemisphere 110 and the ring 109 to move in the groove 112. At the same time, the ring 109 slides on the surface of the cylinder 108, and the stop block 115 can move along the surface of the ring 109 in the limiting groove 113, which can change the position of the ring 109 on the left and right of the stop block 115. When the hemisphere 110 and the ring 109 overlap, the stop block 115 can be released from limiting the hemisphere 110. Then, pull the pull ring 107 upward to move the hemisphere 110 out of the groove 112, thus realizing the quick disassembly of the test mold body 103.
