Description

Technical Field

[0001] This application relates to the field of building material performance testing technology, specifically a mortar consistency tester. Background Technology

[0002] Before construction, the consistency of mortar is usually tested. The consistency of mortar is determined by the weight of a standard cone of a certain geometric shape and weight, which sinks freely into the mortar mixture. The number of centimeters the cone sinks is the consistency value of the mortar. The consistency test is used to determine the mix proportion or to control the consistency of mortar during construction, so as to control the amount of water used.

[0003] Existing mortar consistency laboratories release the testing rod by gradually loosening the screws tightened against the side wall of the testing rod. This gradual release of the testing rod prevents a quick and complete separation between the testing rod and the screws. Consequently, the friction between the screws and the testing rod affects the normal descent of the testing rod and the experimental cone, thus impacting the results and efficiency of mortar consistency testing. Utility Model Content

[0004] To address the shortcomings of existing technologies, this application provides a mortar consistency tester that can quickly and completely release the fixing of the testing rod, allowing the testing rod and experimental cone to fall freely and smoothly. This prevents interference with the falling speed of the testing rod and experimental cone, improving the accuracy and efficiency of mortar consistency testing results. It solves the problem in existing mortar consistency laboratories where releasing the testing rod involves gradually loosening the screws tightened on the side wall of the testing rod. However, this gradual release of the testing rod prevents a quick and complete separation of the testing rod from the screws, leading to friction between the screws and the testing rod affecting the normal falling of the testing rod and experimental cone, thus impacting the results and efficiency of mortar consistency testing.

[0005] To achieve the goal of quickly and completely releasing the fixing of the testing rod, allowing the testing rod and experimental cone to fall freely and smoothly, preventing any impact on their falling speed, and improving the accuracy and efficiency of mortar consistency testing, this application provides the following technical solution: A mortar consistency tester, comprising a base, a support frame at the top of the base, a positioning sleeve at one end of the support frame, a testing rod slidably mounted inside the positioning sleeve, an experimental cone at the bottom of the testing rod, a mortar bucket placed at the top of the base, the mortar bucket located below the experimental cone, a limiting groove formed on one side of the testing rod, a limiting block inserted into the inner wall of the limiting groove, the limiting block being located at one end of the inner telescopic rod of the telescopic rod, one end of the outer telescopic tube of the telescopic rod being mounted on the top of the support frame via a support plate, a spring inside the telescopic rod, one end of the spring being located at one end of the inner telescopic rod of the telescopic rod, the other end of the spring being located at one end of the outer telescopic tube of the telescopic rod, and the spring being in a stretched state when the limiting block is located within the inner wall of the limiting groove.

[0006] The above solution utilizes the spring's tension to rapidly retract the telescopic rod, causing it to quickly pull the limiting block out of the inner wall of the limiting groove. This allows the limiting block to quickly separate from the limiting groove, thereby rapidly releasing the fixing of the testing rod. This achieves quick and complete release of the fixing of the testing rod, allowing the testing rod and experimental cone to fall freely and smoothly, preventing any impact on their falling speed. This improves the accuracy and efficiency of mortar consistency testing results.

[0007] Furthermore, a positioning frame is provided on one side of the outer surface of the middle part of the telescopic inner rod, and a positioning rod is inserted into the inner wall of the middle part of the positioning frame. The outer surface of the middle part of the positioning rod is slidably disposed in the inner wall of one end of the positioning frame, and the other end of the positioning frame is disposed on the top of the support frame.

[0008] With the above solution, when the positioning rod is inserted into the inner wall of the middle of the positioning frame, the positioning rod can cooperate with the positioning frame to fix the extension state of the telescopic rod, thereby fixing the limiting block inside the limiting groove. There is no need to manually fix the extension state of the telescopic rod. Pulling the positioning rod upward in the inner wall of one end of the positioning frame allows the positioning rod to be pulled out of the positioning frame, thereby releasing the restriction on the positioning frame and allowing the telescopic rod to retract normally.

[0009] Furthermore, a positioning ring is provided on the top of the base, the center of the positioning ring is located on the same vertical line as the center of the experimental cone, and the shape and size of the inner wall of the middle part of the positioning ring are adapted to the shape and size of the outer surface of the bottom end of the mortar bucket.

[0010] The above scheme ensures that the positioning ring is accurately placed at the designated position on the base. Since the center of the positioning ring and the center of the experimental cone are on the same vertical line, when the mortar bucket is placed in the positioning ring, it ensures that the experimental cone falls accurately into the mortar bucket. This avoids the situation where the experimental cone falls inaccurately due to the deviation in the placement of the mortar bucket, which would affect the mortar consistency test results and improve the accuracy of the test.

[0011] Furthermore, positioning pulleys are rotatably mounted on all four sides of the inner wall of the positioning sleeve via a rotating shaft. The outer surface of the middle part of the positioning pulleys on the four sides of the inner wall of the positioning sleeve contacts the outer surface of the middle part of the detection rod around the perimeter. The axial direction of the positioning pulleys is perpendicular to the working movement direction of the detection rod.

[0012] The above scheme reduces the friction when the testing rod slides within the positioning sleeve by setting up the positioning pulley. The rolling contact between the positioning pulley and the testing rod, compared to sliding contact, greatly reduces the coefficient of friction, allowing the testing rod to move up and down more smoothly within the positioning sleeve. This reduces the impact of friction on the falling speed of the testing rod and the experimental cone, thereby improving the accuracy of the mortar consistency test results.

[0013] Furthermore, each side of the inner wall of the positioning sleeve is provided with two positioning pulleys via two rotating shafts, and the two positioning pulleys on the same side are distributed vertically.

[0014] The above scheme, with two vertically distributed positioning pulleys on each side, further enhances the stability of the detection rod sliding within the positioning sleeve, fixes the angle of the detection rod when sliding within the positioning sleeve, prevents the detection rod from tilting or wobbling during sliding, and ensures that the detection rod always maintains vertical movement, thus ensuring that the experimental cone can fall vertically and improving the accuracy of the detection.

[0015] Furthermore, a fastening screw is threaded onto one side of the inner wall of the positioning sleeve, and an anti-slip pad is rotatably provided at one end of the fastening screw. The anti-slip pad is located between one side of the detection rod and one side of the inner wall of the positioning sleeve.

[0016] With the above solution, rotating the fastening screw can cause the anti-slip pad to adhere tightly to one side of the detection rod, which can fix the position of the detection rod when reading the test results, allowing for more accurate readings. The anti-slip pad, which is rotated at one end of the fastening screw, can prevent the anti-slip pad from rotating on the outer surface of one side of the detection rod, thus preventing damage to the outer surface of the detection rod.

[0017] Furthermore, a scale is provided on one inner wall of the detection rod, and a pointer is provided in front of the working movement trajectory of the scale. One end of the pointer is set on the top of the positioning slide sleeve through a support rod.

[0018] The above scheme makes it easier for experimenters to read test results by setting up a ruler and pointer. After the test rod and test cone are lowered, the experimenters can directly read the consistency data of the mortar by observing the scale value on the ruler corresponding to the pointer. The operation is simple and convenient, and the testing efficiency is improved.

[0019] Furthermore, a smoothing layer is provided on one side of the scale, and the outer surface of the smoothing layer away from the scale is on the same plane as the outer surface of the detection rod on the corresponding side. The smoothing layer is made of a transparent material.

[0020] The above solution ensures that the smooth layer and the outer surface of the detection rod are on the same plane, thus guaranteeing the integrity of the sliding position of the detection rod inside the positioning sleeve. This prevents the scale from affecting the smoothness of the detection rod's movement inside the positioning sleeve. At the same time, the transparent material of the smooth layer allows workers to read the scale normally through it.

[0021] Compared with the prior art, the technical solution of this application has the following beneficial effects: This mortar consistency tester utilizes a spring to rapidly retract a telescopic rod, causing the rod to quickly pull a limiting block out of the inner wall of the limiting groove. This allows the limiting block to quickly separate from the groove, thereby rapidly releasing the fixing of the testing rod. This ensures the testing rod and the experimental cone can fall freely and smoothly, preventing any impact on their descent speed and improving the accuracy and efficiency of mortar consistency testing.

[0024] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0025] Please see Figure 1 , Figure 3 and Figure 4 This embodiment of a mortar consistency tester includes a base 1, a support frame 2 on the top of the base 1, a positioning sleeve 3 at one end of the support frame 2, a detection rod 4 sliding inside the positioning sleeve 3, an experimental cone 5 at the bottom of the detection rod 4, a mortar bucket 6 placed on the top of the base 1, the mortar bucket 6 located below the experimental cone 5, a limiting groove 7 is formed on one side of the detection rod 4, a limiting block 8 is inserted into the inner wall of the limiting groove 7, the limiting block 8 is set at one end of the inner telescopic rod of the telescopic rod 9, one end of the outer telescopic tube of the telescopic rod 9 is set at the top of the support frame 2 through a support plate, a spring 10 is set inside the telescopic rod 9, one end of the spring 10 is set at one end of the inner telescopic rod of the telescopic rod 9, and the other end of the spring 10 is set at one end of the outer telescopic tube of the telescopic rod 9, the spring 10 is in a stretched state when the limiting block 8 is located in the inner wall of the limiting groove 7.

[0026] Please see Figure 1 , Figure 3 and Figure 4 A positioning frame 11 is provided on one side of the outer surface of the middle part of the telescopic rod 9. A positioning rod 13 is inserted into the inner wall of the middle part of the positioning frame 11. The outer surface of the middle part of the positioning rod 13 is slidably disposed in the inner wall of one end of the positioning frame 12. The other end of the positioning frame 12 is disposed on the top of the support frame 2. When the positioning rod 13 is inserted into the inner wall of the middle part of the positioning frame 11, the positioning rod 13 can cooperate with the positioning frame 12 to fix the extension state of the telescopic rod 9. In this way, the limiting block 8 can be fixed inside the limiting groove 7. There is no need to manually fix the extension state of the telescopic rod 9. Pulling the positioning rod 13 upward in the inner wall of one end of the positioning frame 12 can pull the positioning rod 13 out of the positioning frame 11, thereby releasing the restriction on the positioning frame 11 and allowing the telescopic rod 9 to retract normally.

[0027] Please see Figure 1 , Figure 2 and Figure 4A positioning ring 20 is provided on the top of the base 1. The center of the positioning ring 20 is on the same vertical line as the center of the experimental cone 5. The shape and size of the inner wall of the middle part of the positioning ring 20 are adapted to the shape and size of the outer surface of the bottom end of the mortar bucket 6. The positioning ring 20 can ensure that the mortar bucket 6 is accurately placed in the designated position on the base 1. Since the center of the positioning ring 20 and the center of the experimental cone 5 are on the same vertical line, when the mortar bucket 6 is placed in the positioning ring 20, it can ensure that the experimental cone 5 falls accurately into the mortar bucket 6. This avoids the situation where the experimental cone 5 falls inaccurately due to the deviation of the placement position of the mortar bucket 6, which would affect the mortar consistency test results and improve the accuracy of the test.

[0028] Please see Figure 2 , Figure 4 and Figure 5 Positioning pulleys 14 are rotatably mounted on all four sides of the inner wall of the positioning sleeve 3 via rotating shafts. The outer surface of the middle part of the positioning pulleys 14 on the four sides of the inner wall of the positioning sleeve 3 contacts the outer surface of the middle part of the detection rod 4. The axial direction of the positioning pulleys 14 is perpendicular to the working movement direction of the detection rod 4. The setting of the positioning pulleys 14 reduces the friction force when the detection rod 4 slides in the positioning sleeve 3. The positioning pulleys 14 and the detection rod 4 are in rolling contact, which greatly reduces the coefficient of friction compared to sliding contact. This allows the detection rod 4 to move up and down more smoothly in the positioning sleeve 3, reducing the influence of friction on the falling speed of the detection rod 4 and the experimental cone 5, thereby improving the accuracy of the mortar consistency test results.

[0029] Please see Figure 2 , Figure 3 and Figure 4 Each side of the inner wall of the positioning sleeve 3 is equipped with two positioning pulleys 14 rotatably mounted via two rotating shafts. The two positioning pulleys 14 on the same side are distributed vertically. The arrangement of two vertically distributed positioning pulleys 14 on each side further enhances the stability of the detection rod 4 sliding within the positioning sleeve 3, fixes the angle of the detection rod 4 when sliding within the positioning sleeve 3, and prevents the detection rod 4 from tilting or shaking during the sliding process. This ensures that the detection rod 4 always maintains vertical movement, ensuring that the experimental cone 5 can fall vertically and improving the accuracy of the detection.

[0030] Please see Figure 1 , Figure 2 and Figure 5A fastening screw 15 is threaded onto the inner wall of one side of the positioning sleeve 3. An anti-slip pad 16 is rotatably mounted on one end of the fastening screw 15. The anti-slip pad 16 is located between one side of the detection rod 4 and one side of the inner wall of the positioning sleeve 3. By rotating the fastening screw 15, the anti-slip pad 16 can be driven to stick tightly to one side of the detection rod 4. This can fix the position of the detection rod 4 when reading the test results, allowing for more accurate readings. The anti-slip pad 16, rotatably mounted on one end of the fastening screw 15, can prevent the anti-slip pad 16 from rotating on the outer surface of one side of the detection rod 4, thus preventing damage to the outer surface of the detection rod 4.

[0031] Please see Figure 1 , Figure 2 and Figure 6 A scale 17 is installed on the inner wall of one side of the detection rod 4. A pointer 19 is located in front of the working movement trajectory of the scale 17. One end of the pointer 19 is set on the top of the positioning sleeve 3 through a support rod. The setting of the scale 17 and the pointer 19 makes it convenient for the experimenter to read the test results. After the detection rod 4 and the experimental cone 5 are lowered, the experimenter can directly read the consistency data of the mortar by observing the scale value on the scale 17 corresponding to the pointer 19. The operation is simple and convenient, and the testing efficiency is improved.

[0032] Please see Figure 1 , Figure 2 and Figure 6 A smooth layer 18 is provided on one side of the scale 17. The outer surface of the smooth layer 18 away from the scale 17 is on the same plane as the outer surface of the detection rod 4. The smooth layer 18 is made of transparent material. The fact that the smooth layer 18 and the outer surface of the detection rod 4 are on the same plane can ensure the integrity of the sliding position of the detection rod 4 inside the positioning sleeve 3 and prevent the setting of the scale 17 from affecting the smoothness of the detection rod 4 when sliding inside the positioning sleeve 3. At the same time, the smooth layer 18 made of transparent material allows the operator to read the scale 17 normally through the smooth layer 18.

[0033] In this embodiment, a mortar consistency tester utilizes the tension of spring 10 to rapidly retract the telescopic rod 9. This causes the telescopic rod 9 to quickly pull the limiting block 8 out of the inner wall of the limiting groove 7, allowing the limiting block 8 to quickly separate from the limiting groove 7. This, in turn, quickly releases the fixation on the testing rod 4, achieving rapid and complete release of the fixation on the testing rod 4. This allows the testing rod 4 and the experimental cone 5 to fall freely and smoothly, preventing any impact on their falling speed. This improves the accuracy and efficiency of the mortar consistency test results.

[0034] The working principle of the above embodiment is as follows: A mortar bucket 6 containing the mortar to be tested is placed inside the positioning ring 20 at the top of the base 1. The fastening screw 15 is rotated, causing the anti-slip pad 16 to gradually move away from the detection rod 4, completely separating the anti-slip pad 16 from the detection rod 4. The positioning rod 13 is pulled upwards, pulling it out from the inner wall of the middle part of the positioning frame 11. The spring 10 releases its tension, pulling the telescopic rod 9 to retract, causing the telescopic rod 9 to quickly pull the limiting block 8 out from the inside of the limiting groove 7, separating the limiting block 8 from the detection rod 4. The limiting block 8 is completely released from the detection through the limiting groove 7. Due to the constraint of the measuring rod 4, the measuring rod 4 and the experimental cone 5 fall freely under gravity, causing the measuring rod 4 to slide downward inside the positioning sleeve 3, and causing the experimental cone 5 to fall into the mortar in the mortar bucket 6. According to the experimental requirements, wait for the experimental cone 5 to settle in the mortar bucket 6. After the waiting period, rotate the fastening screw 15 to move the anti-slip pad 16 towards the measuring rod 4, so that the anti-slip pad 16 is in close contact with one side of the outer surface of the measuring rod 4, fixing the position of the measuring rod 4. The distance of the measuring rod 4 and the experimental cone 5 falling is read by the pointer 19 and the scale 17, and then the experimental result is obtained.
