DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Embodiment 1: This embodiment is intended to help solve the problem that the concrete sample may move or deform during the test process, especially when conducting compressive strength tests, the sample needs to be subjected to uniform force loading, which may cause excessive local stress in the sample and cause damage, affecting the accuracy of the test results. Please refer to Figure 1-Figure 4 A concrete quality testing device includes a base 100, a testing platform 200, and a pressure testing head 210. The testing platform 200 is installed on the base 100. A support frame 110 is installed on the side of the testing platform 200. The support frame 110 is installed on the base 100. A control rod 111 for controlling the pressure testing head 210 is installed on the support frame 110. The pressure testing head 210 is installed at the end of the control rod 111. A clamping assembly 300 for clamping a sample is arranged in the testing platform 200.

[0024] The clamping assembly 300 includes a control chamber 310 opened in the testing platform 200, a fixed seat 320 is installed in the control chamber 310, a lifting rod 321 is installed on the fixed seat 320, a pressure plate 330 is installed at the end of the lifting rod 321, a groove 120 is opened on the testing platform 200, the pressure plate 330 is inserted into the groove 120, a slide rail 340 is set on the side of the fixed seat 320, a movable rod 350 is installed on the slide rail 340, a movable groove 130 is opened on the testing platform 200, the movable rod 350 is inserted into the movable groove 130, and a clamping plate 360 ​​is installed at the end of the movable rod 350.

[0025] The slide rail 340, the movable rod 350 and the clamping plate 360 ​​are all provided in two groups, and the two groups of the slide rail 340, the movable rod 350 and the clamping plate 360 ​​are symmetrically arranged on both sides of the fixed seat 320. A pulley 351 corresponding to the slide rail 340 is installed at the bottom of the movable rod 350, and the movable rod 350 is installed on the slide rail 340 through the pulley 351 slideway, and a limit plate 341 is installed at the end of the slide rail 340.

[0026] A first fixing hook 331 is installed on the side of the pressure plate 330, and a second fixing hook 352 is installed on the side of the movable rod 350. A driving chain 332 is connected between the first fixing hook 331 and the second fixing hook 352. A through hole 342 is opened on the limiting plate 341, and the driving chain 332 is fixedly connected to the second fixing hook 352 through the through hole.

[0027] When testing a concrete sample, after the operator places the sample to be tested on the test table 200, gravity causes the pressing plate 330 to move downward, and at the same time, the second fixing hook 352 drives the chain 332 to move downward synchronously, pulling the movable rod 350 to move to the test sample position in the slide rail 340, and the clamping plate 360 ​​clamps the sample. This design ensures that the sample is subjected to uniform force loading, avoiding the problem of accuracy of the test result caused by excessive local stress. The working principle of this clamping assembly 300 can effectively solve the problem of test inaccuracy that may be caused by sample movement or deformation, and improve the reliability and stability of the detection equipment.

[0028] In this embodiment: through the design of the clamping assembly 300, after the sample is placed on the test bench 200, the pressing plate 330 moves downward and clamps the sample, the second fixed hook 352 drives the chain 332 to synchronously move the movable rod 350, the movable rod 350 moves to the sample position in the slide rail 340, and the clamping plate 360 ​​clamps the sample, thereby achieving stable clamping and uniform force loading of the sample, improving the accuracy and reliability of the test process, ensuring the accuracy of the test results, and solving the problem of sample movement or deformation that may occur in concrete sample testing.

[0029] Embodiment 2: This embodiment is intended to facilitate solving the problem that the movable rod 350 may be unstable when restoring its position during operation. This embodiment is an improvement made on the basis of Embodiment 1. For details, please refer to Figure 1-Figure 4 .

[0030] The lifting rod 321 is provided with a first spring 322, one end of the first spring 322 is connected to the bottom of the pressure plate 330, and the other end of the first spring 322 is connected to the top of the fixing seat 320. The side of the movable rod 350 is provided with a second spring 353, one end of the second spring 353 is connected to the side of the movable rod 350 close to the inside of the control chamber 310, and the other end of the second spring 353 is connected to the inner wall of the control chamber 310.

[0031] The first spring 322 is connected between the bottom of the pressing plate 330 and the fixing seat 320. When the pressing plate 330 moves downward to clamp the sample, the first spring 322 provides a certain elastic support to help maintain stability and uniformity during the clamping process. At the same time, the first spring 322 also has the ability to recover, that is, it can help the pressing plate 330 return to its original position after the clamping is completed.

[0032] The second spring 353 is connected to the movable rod 350 and the inner wall of the control chamber 310. It provides elastic support during the clamping process to ensure that the clamping force of the clamping plate 360 ​​on the sample is uniform and stable. After the clamping is completed, the second spring 353 can assist the movable rod 350 to return to its original position to maintain the normal operation of the device.

[0033] An extension plate 361 for fixing the clamping plate 360 ​​is installed transversely at the end of the movable rod 350, and the clamping plate 360 ​​is fixedly installed on the side of the movable rod 350 close to the pressure plate 330. The clamping plate 360 ​​can clamp the sample more stably to ensure the uniform distribution and stability of the clamping force. At the same time, the fixed position of the clamping plate 360 ​​also helps to improve the accuracy and reliability of the equipment during the test process, avoiding the situation where the clamping plate 360 ​​slides or tilts, which may cause errors in the test results.

[0034] In this embodiment: by setting the first spring 322 and the second spring 353, it is ensured that the clamping force of the clamping plate 360 ​​on the sample is evenly distributed and stable, and at the same time helps the device to return to its original position after the clamping operation and maintain the normal operating state of the device. The setting of the extension plate 361 further reinforces the fixed position of the clamping plate 360, so that the sliding or tilting of the clamping plate 360 ​​can be avoided, thereby improving the accuracy and reliability of the test.

[0035] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0036] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
