DETAILED DESCRIPTION

[0020] Please refer to Figures 1-6The utility model provides following technical scheme: a geosynthetic material top breaking test sample clamping tool, including base 1, top frame 2, upper ring 3 and puncture rod 6, still including fixed establishment 4, the top of base 1 is equipped with controller 11, telescopic cylinder 12 and bottom frame 21, the top of base 1 is projected and is slidably installed with top frame 2 connected with telescopic cylinder 12, top frame 2 is installed with puncture rod 6 through telescopic cylinder 12, the inner wall of bottom frame 21 is installed with lower ring 31, and lower ring 31 is equipped with upper ring 3, and upper ring 3 and lower ring 31 are equipped with the hole of array cooperation, and upper ring 3 and lower ring 31 cooperation hole are installed with fixed pin 41, and lower ring 31 is rotatably installed with gear ring 43, and the inside rotation of lower ring 31 is installed with a plurality of cam 45 matched with the side wall recess of fixed pin 41, and cam 45 is installed with the gear 44 engaged with gear ring 43.

[0021] The controller 11 controls the operation of each electrically powered component of the device. The piercing rod 6 is used to push the material to be tested, realizing the detection of the piercing force of the material by the device. The telescopic cylinder 12 controls the movement of the piercing rod 6. The piercing rod 6 has a pressure detection component inside. The user can determine the force applied by the piercing rod 6 to the material to be tested when it pierces the material through the controller 11. The telescopic cylinder 12 has a top frame 2. The cooperation of the top frame 2, bottom frame 21 and the top protrusion of the base 1 can form a sealed protective chamber on the outside of the upper ring 3 and the lower ring 31. The protective chamber on the outside of the upper ring 3 can prevent the debris of the material to be tested from splashing to the outside of the device after it is pierced. The material blocked by the protective chamber is easy for the user to test. The protective chamber cleans up debris generated after material breakage while preventing flying material from hitting the user. It ensures the cleanliness of the external environment and protects the user. The top frame 2 has a T-shaped protrusion on its side wall, and the top protrusion of the base 1 has a groove that mates with the protrusion on the side wall of the top frame 2. The engagement of the protrusion and the groove on the side wall of the top frame 2 provides a limiting function, ensuring the stability of the top frame 2 during movement. The top frame 2 and the bottom frame 21 are made of transparent material, allowing the user to easily determine the actual condition of the material being tested. A sealing plate is hinged to the side wall of the bottom frame 21 via a torsion spring shaft. The user can clean debris inside the bottom frame 21 through the groove where the sealing plate is installed. The bottom surface of the base frame 21 is sloping towards the side wall of the base frame 21. The shape of the base surface facilitates cleaning of debris. The installation method of the side wall of the base frame 21 ensures the stability of the sealing plate during device use, thereby guaranteeing the working effect of the protective chamber. The upper ring 3 and lower ring 31 are used to fix the material to be tested. The fixing mechanism 4 is used to fix the upper ring 3 and lower ring 31 placed together. When using the device, the material to be tested is placed on the lower ring 31, and then the upper ring 3 is placed on the lower ring 31. The material to be tested is clamped by the upper ring 3 and lower ring 31. During material testing, holes are drilled in the material to be tested to match the holes provided on the upper ring 3 and lower ring 31. The fixing pin 41 is then passed through the upper ring 3, lower ring 31, and the material to be tested. The material has holes in it. Rotating the gear ring 43 causes the gear 44, which meshes with the gear ring 43, to rotate. The rotating gear 44 then rotates the cam 45, which enters the side wall groove of the fixing pin 41. At this point, the fixing pin 41 is fixed by the cooperation between the cam 45 and the side wall groove. The fixed pin 41 serves to fix the upper ring 3 and the lower ring 31. The upper ring 3 and the lower ring 31, fixed by the fixing pin 41, thus fix the material to be tested. The fixing mechanism 4 ensures that the user can select a suitable length of fixing pin 41 according to the thickness of the material to be tested, making the device applicable to materials of different thicknesses. Rubber pads are provided on the opposite side walls of the upper ring 3 and the lower ring 31.The rubber pad reduces damage to the material to be detected during fixation, and the side wall of the tooth ring 43 is provided with a protrusion. The protrusion on the side wall of the tooth ring 43 provides a force position for the user to rotate the tooth ring 43, facilitating the rotation of the tooth ring 43 by the user.

[0022] Specifically, the upper ring 3 is provided with a protrusion matched with the protrusion on the side wall of the lower ring 31, and the protrusion on the side wall of the upper ring 3 is hingedly connected with a fixed block 42 through a torsion spring shaft, and the protrusion on the side wall of the lower ring 31 is provided with a groove matched with the fixed block 42.

[0023] The cooperation between the fixed block 42 and the groove matched therewith plays a role in fixing the tooth ring 43, and the fixed tooth ring 43 ensures the stability of the cam 45, thereby ensuring the fixing effect of the upper ring 3 and the lower ring 31 on the material to be detected. The fixed block 42 is hingedly connected to the protrusion on the side wall of the upper ring 3 through a torsion spring shaft, and the installation mode of the fixed block 42 ensures the stability of the fixed block 42 during use of the device, thereby ensuring the fixing effect of the fixed block 42 on the tooth ring 43. The side wall shape at the opening of the groove matched with the fixed block 42 is a slope, and the slope side wall of the groove matched with the fixed block 42 plays a guiding role, facilitating the user to move the fixed block 42 into the interior of the groove matched therewith.

[0024] Specifically, the shape of the bottom of the side wall of the cam 45 is a slope inclined to the interior of the cam 45.

[0025] When the fixed pin 41 is installed on the fixing mechanism 4 and the upper ring 3 and the lower ring 31 are not fixed, the upper ring 3 and the lower ring 31 are not subjected to external force and cannot effectively fix the material to be detected. At this time, the bottom surface of the side wall groove of the fixed pin 41 is slightly higher than the bottom surface of the cam 45. When the cam 45 rotates, the slope portion of the side wall of the cam 45 contacts the edge of the bottom surface of the side wall groove of the fixed pin 41. As the cam 45 continues to rotate, the fixed pin 41 moves downward under the impetus of the cam 45. The downward moving fixed pin 41 plays a role in pressing the upper ring 3, and the upper ring 3 pressed by the fixed pin 41 ensures the fixing effect of the cooperation between the upper ring 3 and the lower ring 31 on the material to be detected.

[0026] Specifically, the top surface of the lower ring 31 is higher than the top surface of the bottom frame 21.

[0027] The height of the top surface of the lower ring 31 ensures that when the user places the material to be detected on the lower ring 31, the bottom frame 21 will not hinder the user from installing the material to be detected, facilitating the user to install the material to be detected.

[0028] Specifically, the interior of the upper ring 3 and the lower ring 31 is provided with a magnet 5 matched therewith.

[0029] When the user does not install the fixing pin 41 on the upper ring 3 and the lower ring 31, the upper ring 3 and the lower ring 31 are adsorbed together by the internally arranged magnet 5, and the upper ring 3 and the lower ring 31 fixed by the magnet 5 can avoid the holes arranged on the upper ring 3 and the lower ring 31 from being staggered, so as to facilitate the user to install the fixing pin 41 on the upper ring 3.

[0030] Specifically, the inner wall of the bottom frame 21 is provided with a sliding rod 24, and the cleaning brush 22 is slidingly installed on the sliding rod 24. The inner wall of the bottom frame 21 is provided with a self-reel line shaft connected with the cleaning brush 22 through a pull line.

[0031] The cleaning brush 22 is used for cleaning the debris inside the bottom frame 21. The cleaning brush 22 is slidingly installed on the sliding rod 24. When the user moves the cleaning brush 22, the pull line connected with the cleaning brush 22 is pulled, and the pulled pull line drives the self-reel line shaft to rotate. When the user releases the cleaning brush 22, the cleaning brush 22 is pulled back to the original position under the action of the self-reel line shaft, realizing the automatic storage of the self-reel line shaft to the cleaning brush 22. The length of the pull line wound on the self-reel line shaft is ensured, so that the cleaning brush 22 will not be separated from the sliding rod 24 during movement, ensuring the stability of the cleaning brush 22 during movement.

[0032] Specifically, the end face of the sliding rod 24 is provided with a pull block 23, and the pull block 23 is connected with the cleaning brush 22 through a pull line. The pull line arranged on the pull block 23 is located inside the bottom surface groove of the sliding rod 24.

[0033] The pull block 23 is installed on the end face groove of the sliding rod 24 through the side wall groove. The installation mode of the pull block 23 ensures the stability of the pull block 23 during use of the device. When the user pulls the pull block 23, the pull block 23 moves with the cleaning brush 22 through the pull line, facilitating the user to clean the debris inside the bottom frame 21 through the cleaning brush 22. The position of the pull line arranged on the pull block 23 reduces the influence of the pull line arranged on the pull block 23 during use of the device, ensuring the stability of the connection between the cleaning brush 22 and the pull block 23.

[0034] The working principle and use process of the utility model are as follows: the upper ring 3 is taken off from the lower ring 31, the material to be detected is placed on the lower ring 31, the fixing pin 41 is installed on the upper ring 3 and the lower ring 31, the tooth ring 43 is rotated, the rotating tooth ring 43 drives the gear 44 to rotate, the rotating gear 44 drives the cam 45 to rotate, the rotating cam 45 enters the inside of the side wall groove of the fixing pin 41, at this time the fixing pin 41 is fixed, the fixed fixing pin 41 fixes the upper ring 3 and the lower ring 31, the fixed upper ring 3 and the lower ring 31 fix the material to be detected, the fixing block 42 is screwed into the matched groove, the fixing mechanism 4 is locked, the position of the top frame 2 is adjusted through the telescopic cylinder 12, the top frame 2 and the bottom frame 21 are combined together, the piercing rod 6 is moved through the telescopic cylinder 12, the moving piercing rod 6 pierces the material to be detected, after the detection is finished, the piercing rod 6 is controlled to return to the original position, the side wall sealing plate of the bottom frame 21 is rotated, the pull block 23 is pulled, the cleaning brush 22 is pulled by the pull block 23, the pulled cleaning brush 22 cleans the chippings in the bottom frame 21, along with the movement of the cleaning brush 22, the self-reel reel connected with the cleaning brush 22 is pulled, after the cleaning is finished, the pull block 23 is released, the cleaning brush 22 and the pull block 23 return to the original position under the action of the self-reel reel.
