Description

Technical Field

[0001] This utility model belongs to the field of concrete testing technology, and in particular relates to a sample fixing device for testing the permeability of concrete bricks. Background Technology

[0002] Concrete brick permeability testing is a test to evaluate the water permeability performance of concrete bricks. It is typically used to determine the permeability of a material, thereby judging its suitability for applications such as rainwater management and paving. Determining how much water a concrete brick allows to pass through per unit time directly affects drainage performance. Fixing devices are often designed according to a standard size, which cannot flexibly adapt to specimens of different sizes or shapes. Because the specimen fixing devices in related technologies cannot be adjusted according to the size of the concrete bricks, the devices may not be universally applicable when testing multiple specifications of concrete bricks, leading to limitations in their use. Summary of the Invention

[0003] In view of this, the present invention aims to at least partially solve one of the related technical problems.

[0004] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0005] A sample fixing device for testing the permeability of concrete bricks includes a sample base, a flow guiding structure, two side plates, two elastic adjustment mechanisms, four sealing structures, two baffles, and two sample fixing plates.

[0006] The two side plates are symmetrically arranged on the upper surface of the sample base, and each side plate is detachably connected to the sample base.

[0007] The two baffles are arranged symmetrically on the left and right, and the ends of the two side plates are detachably connected to one of the side plates. The two sample fixing plates are arranged symmetrically on the left and right, and the two sample fixing plates are located between the two side plates. Each side plate is connected to one of the sample fixing plates through an elastic adjustment mechanism. The sample fixing plate is located inside the baffle.

[0008] Each of the sample fixing plates has a sealing structure at its front and rear ends that slides in conjunction with the side plate.

[0009] The flow guiding structure is disposed in the middle of the upper end face of the two side plates, and the flow guiding structure is detachably connected to the two side plates;

[0010] The left and right ends of the sample base are each provided with a first connecting plate for connecting to the operating table.

[0011] Furthermore, the elastic adjustment mechanism includes four adjusting push rods, four compression springs, and four limiting blocks. The four adjusting push rods are symmetrically arranged front and back. Each adjusting push rod passes through the baffle. The inner end of the adjusting push rod is threaded to the sample fixing plate, and the outer end of the adjusting push rod is correspondingly connected to one of the limiting blocks. Each adjusting push rod is correspondingly provided with a compression spring, which is located between the baffle and the sample fixing plate.

[0012] Furthermore, the inner end face of the side plate is provided with a guide groove, and the sealing structure includes a movable slider and a sealing block. The movable slider is disposed at the end of the sample fixing plate, and the movable slider slides in cooperation with the guide groove through the sealing block.

[0013] Furthermore, the flow guiding structure includes a flow guiding plate and two second connecting plates. The upper end face of the flow guiding plate is provided with a flow guiding groove, and a plurality of leakage holes are symmetrically arranged in the flow guiding groove. The front and rear sides of the flow guiding plate are connected to the upper end face of the side plate through a second connecting plate.

[0014] Furthermore, the flow guiding structure also includes two flow guiding plates, which are arranged symmetrically on the left and right sides, and each flow guiding plate is inclined at the end of the flow guiding plate.

[0015] Furthermore, a third connecting plate is provided at the bottom of the side plate, and the third connecting plate is connected to the sample base by multiple connecting bolts.

[0016] Furthermore, the second connecting plate is inclinedly disposed on the side of the guide plate.

[0017] Compared with existing technologies, the sample fixing device for testing the permeability of concrete bricks described in this utility model has the following advantages:

[0018] 1. The elastic adjustment mechanism, through the combination of the adjusting push rod and the clamping spring, allows for convenient adjustment of the sample fixing plate position, thus accommodating samples of different thicknesses and sizes to meet diverse testing needs. Clamping and releasing the sample is accomplished simply by raising and lowering the adjusting push rod, reducing complex operations and improving work efficiency. The clamping spring provides continuous pressure, ensuring the stability of the sample during testing.

[0019] 2. The sealing structure, through the combination of the movable slider and the sealing block, ensures a tight fit between the sample and the side plate after installation, preventing water leakage from gaps during the test and ensuring the accuracy of the test data.

[0020] 3. The guide channels and leakage holes on the guide plate effectively disperse the water flow evenly onto the sample surface, ensuring the consistency and stability of the water flow during the test, thereby improving the accuracy of the test results. Guiding the water flow smoothly into the sample surface reduces turbulence and fluctuations, making test conditions more controllable and improving data repeatability and reliability. The guide structure and side plate are detachably connected, facilitating installation, adjustment, and maintenance. The guide plate can be replaced or adjusted according to different experimental needs, increasing the adaptability of the equipment. Attached Figure Description

A first connecting plate 102 for connecting to the operating table is provided at the left and right ends of the sample base 101.

[0033] like Figure 3As shown, the front and rear ends of each sample fixing plate 302 are slidably engaged with the side plate 201 through a sealing structure; a flow guiding structure is set in the middle of the upper end face of the two side plates 201, and the flow guiding structure is detachably connected to the two side plates 201; a guide groove 603 is provided on the inner end face of the side plate 201; the sealing structure includes a movable slider 601 and a sealing block 602; the movable slider 601 is set at the end of the sample fixing plate 302, and the movable slider 601 is slidably engaged with the guide groove 603 through the sealing block 602.
