Detailed Implementation

[0024] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate the technical solution of this utility model, but should not be used to limit the scope of protection of this utility model.

[0025] Example:

[0026] like Figures 1 to 7As shown, this utility model provides a portable concrete strength testing device, including a testing instrument body 101. The testing instrument body 101 is equipped with an auxiliary bonding component, which includes a support frame 102. The support frame 102 provides structural support for the entire auxiliary bonding component, facilitating the installation and coordinated operation of other parts. A slider 103 is slidably mounted within the support frame 102, and the slider 103 is connected to the testing instrument body 101 via a fixing member. The slider 103 and the fixing member allow for adjustment and fixation of the relative position of the testing instrument body 101 within the support frame 102, adapting to different testing scenarios. An adsorption component is located at the bottom of the support frame 102, comprising an air pump 201 and multiple sets of suction cups 202. The multiple sets of suction cups 202 are circumferentially distributed at the bottom of the support frame 102 and connected to the air pump 201 via an air extraction pipe 203. With the air pump 201, suction cup 202 and air extraction pipe 203, the device can draw air through the air pump 201 and allow the suction cup 202 to adhere to the concrete surface, ensuring that the detection device is in close contact with the detection surface.

[0027] like Figure 2 , 5 As shown in Figures 6 and 7, the support frame 102 is a hollow cone shape. At least three sets of slide rails 301 are evenly distributed circumferentially within the support frame 102. The outer wall of the slider 103 has protrusions 302 matching the number of slide rails 301. The protrusions 302 are embedded inside the corresponding slide rails 301. A limiting ring 303 is provided at the open end of each slide rail 301, and the limiting ring 303 is connected to the support frame 102. Through the arrangement of the slide rails 301, protrusions 302, and limiting rings 303, guidance and limitation are provided for the sliding of the slider 103 within the support frame 102, ensuring the stability of the slider 103's sliding motion.

[0028] The fixing component includes four sets of pressure blocks 304, and four sets of guide grooves 305 are provided on the inner wall of the slider 103. The pressure blocks 304 are located in the guide grooves 305. Through the arrangement of the pressure blocks 304 and the guide grooves 305, the pressure blocks 304 can move within the guide grooves 305 to achieve the clamping or loosening action of the detector body 101. A guide rail ring 306 is provided inside the slider 103, and four sets of guide blocks 307 are provided inside the guide rail ring 306. The guide blocks 307 contact the pressure blocks 304. Through the arrangement of the guide rail ring 306 and the guide blocks 307, a track is provided for the movement of the guide blocks 307, and the guide blocks 307 push the pressure blocks 304 to fix the detector body 101. The bottom and sidewalls of the guide ring 306 are respectively provided with a first limiting groove 308 and a second limiting groove 309. Both the guide block 307 and the pressure block 304 are provided with limiting blocks 311. The limiting block 311 of the guide block 307 is located within the first limiting groove 308, and the limiting block 311 of the pressure block 304 is located within the second limiting groove 309. The setting of the first limiting groove 308, the second limiting groove 309, and the limiting blocks 311 can limit the movement range of the guide block 307 and the pressure block 304, ensuring that each part of the fixing component works in a reasonable position and guaranteeing the reliability of fixing the detector body 101.

[0029] like Figure 2 , 3 As shown. A rotating ring 312 is provided at the top of the slider 103. The guide block 307 is connected to the rotating ring 312. A ratchet 314 is provided at the top of the rotating ring 312. Through the arrangement of the rotating ring 312 and the ratchet 314, power can be transmitted to the movement of the guide block 307, and the ratchet 314 structure can realize a one-way locking function. A mounting ear 104 is provided on one side of the slider 103. A pawl 315 and a fixing spring 316 are provided on the mounting ear 104. Two sets of mounting posts 105 are provided on the mounting ear 104. The pawl 315 is mounted on one set of mounting posts 105. One end of the fixing spring 316 is connected to the other set of mounting posts 105, and the other end of the fixing spring 316 is connected to the pawl 315. The pawl 315 engages with the ratchet 314. By installing the ear 104, pawl 315, fixing spring 316 and mounting post 105, the pawl 315 can engage with the ratchet 314, and under the action of the fixing spring 316, the rotation of the rotating ring 312 can be locked in one direction, thereby fixing the position of the guide block 307 and the pressure block 304, and further fixing the detector body 101.

[0030] like Figure 2 , 4As shown, an air pump 201 is located on one side of the support frame 102. Multiple suction cups 202 are equipped with air extraction holes 204, all of which are connected to the air pump 201 via air extraction pipes 203. The air pump 201, air extraction holes 204, and air extraction pipes 203 form a complete air extraction and adsorption system. The air pump 201 extracts air from the suction cups 202 through the air extraction pipes 203, enabling the suction cups 202 to adsorb onto the concrete surface. An air release valve 205 is provided on the air extraction pipe 203. This valve allows for easy release of the vacuum inside the suction cups 202 after testing, facilitating easy separation of the device from the concrete surface. A flexible sealing ring 206 is located at the bottom of the suction cups 202. The flexible sealing ring 206 improves the sealing effect between the suction cups 202 and the concrete surface, enhances the adsorption force, and adapts to concrete surfaces with varying flatness.

[0031] The support frame 102 has symmetrically arranged folding handles 106 on its walls, which are hinged to the support frame 102 via pivots 107. The folding handles 106 and pivots 107 facilitate the gripping and movement of the device by the testing personnel, and the handles can be folded when not in use, reducing space occupation. A bubble level 108 is embedded in the side wall of the support frame 102. The bubble level 108 assists the testing personnel in adjusting the testing device to a horizontal position, ensuring that the device is perpendicular to the testing surface during testing and improving the accuracy of the test results.

[0032] The specific usage and function of this embodiment are as follows:

[0033] When using this portable concrete strength testing device, the operator first holds and moves the device to the concrete structure to be tested using the folding handle 106. Unfolding the handle 106, the operator uses the bubble level 108 to adjust the device to a horizontal position, ensuring it is perpendicular to the testing surface during testing. Next, if the position of the testing instrument body 101 needs adjustment, the rotating ring 312 can be operated. The rotating ring 312 drives the guide block 307 to move within the guide rail ring 306. The guide block 307 pushes the pressure block 304 to move within the guide groove 305 of the slider 103, thereby releasing or clamping the testing instrument body 101, achieving position adjustment and fixation. Due to the cooperation of the slide rail 301, the protrusion 302, and the limiting ring 303, the slider 103 slides stably within the support frame 102. Once the location is determined, the air pump 201 is activated. The air pump 201 draws air from the suction port 204 on the suction cup 202 through the suction pipe 203, causing the suction cup 202 to adhere to the concrete surface. The flexible sealing ring 206 further enhances the sealing effect, ensuring the device is in close contact with the test surface. At this time, the ratchet 314 and pawl 315 cooperate, locking the position of the rotating ring 312 under the action of the fixing spring 316, thus fixing the detector body 101. After the test is completed, the venting valve 205 is opened to release the vacuum inside the suction cup 202, and the device is removed. During the test, all components of the device work together to ensure the accuracy and reliability of the test results.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments.
