Description

Technical Field

[0001] This utility model relates to the field of consistency measuring instruments, and in particular to a consistency measuring instrument. Background Technology

[0002] In related technologies, mortar consistency testers typically use screws to fix the sliding rod. During use, the test cone must first be adjusted to zero, then the brake screw must be manually loosened to release the sliding rod, allowing the test cone to fall freely into the mortar for testing. After the test, the sliding rod must be manually pulled back to its original position, zeroed again, and the screw tightened. This operation method is not only cumbersome and inefficient, but the frequent tightening of the screws can also easily cause wear and cracking of the plastic support, affecting the stability and lifespan of the instrument.

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0022] like Figures 1 to 3 As shown, the consistency measuring instrument 100 of this utility model embodiment includes a frame 1, a measuring component 2, a driving assembly 3, a fixing rod 4, and a pin 5.

[0023] The bottom of the frame 1 is equipped with a slurry container 11.

[0024] The measuring component 2 is movably mounted on the frame 1 along the first direction, including a slide rod 21 and a test cone 22. The test cone 22 is located at the bottom of the slide rod 21, and the slide rod 21 is provided with a scale line 23 and a first insertion hole 24.

[0025] The drive assembly 3 includes a drive member 31 and a pull rope 32. One end of the pull rope 32 is wound around the drive member 31, and the other end of the pull rope 32 is fixedly connected to the slide bar 21.

[0026] The fixed rod 4 is connected to the frame 1 and has a guide hole extending in the first direction. The slide rod 21 passes through the guide hole and can slide along it. The fixed rod 4 has a second insertion hole that communicates with the guide hole. The fixed rod 4 has a reference piece that corresponds to the zero position of the scale line 23.

[0027] The pin 5 is detachably inserted into the first socket 24 and the second socket for releasing or locking the measuring element 2.

[0028] For ease of description, the technical solution of this application will be described below with the vertical direction as the first direction, where the vertical direction is as follows: Figure 1 As shown.

[0029] The bottom of the frame 1 is provided with a mortar container 11 for holding mortar, so as to hold test mortar.

[0030] The measuring element 2 is movable on the frame 1 in the vertical direction. The measuring element 2 includes a slide rod 21 and a test cone 22 installed at the bottom of the slide rod 21. The slide rod 21 is provided with a scale line 23 and a first insertion hole 24 for locking.

[0031] The drive assembly 3 includes a drive member 31 and a pull rope 32. One end of the pull rope 32 is wrapped around the drive member 31, and the other end is fixedly connected to the slide rod 21. The pull rod 21 is pulled by the rotation of the drive member 31.

[0032] The fixing rod 4 is connected to the frame 1 and has a guide hole extending vertically inside. The sliding rod 21 passes through the guide hole and can slide up and down in it.

[0033] The fixing rod 4 is also provided with a second insertion hole aligned with the first insertion hole 24, and a reference piece for calibrating the zero position. Before the test begins, the reference piece is aligned with the zero mark position of the scale line 23 on the slide rod 21.

[0034] The pin 5 can be detachably inserted into both the first and second sockets to lock or release the measuring element 2.

[0035] During use, the test slurry is first poured into the slurry container 11, and the test cone 22 is adjusted to a position close to the mortar surface. The locking of the measuring element 2 is released by pulling out the pin 5. Then, the drive component 31 (such as a motor) in the drive assembly 3 is activated, causing it to rotate in a preset direction. The pull rope 32 is released accordingly, and the measuring element 2, under its own weight, causes the test cone 22 to fall freely and insert into the mortar. The insertion depth is directly read from the scale line 23 on the slide rod 21. The value of the scale line 23 corresponding to the reference element is the insertion depth.

[0036] After the test is completed, the drive component 31 is rotated in reverse by the reset switch, the pull rope 32 is rewound, the slide bar 21 and the test cone 22 are lifted and reset to the initial position, and then the pin 5 is re-inserted into the first socket 24 and the second socket to complete the locking and prepare for the next test.

[0037] The pin 5 ensures that the test cone 22 remains firmly in the zero position and does not move around. Furthermore, the pin 5 locks the test cone 22, preventing its weight from being transmitted to the drive unit 31 via the pull rope 32, thus preventing the drive unit 31 from being constantly under stress and affecting its lifespan.

[0038] In related technologies, mortar consistency testers typically use screws to fix the slide bar 21. During use, the test cone 22 must first be adjusted to zero, then the brake screw must be manually loosened to release the slide bar 21, allowing the test cone 22 to fall freely into the mortar for testing. After the test, the slide bar 21 must be manually pulled back to its original position, zeroed again, and the screw tightened. This operation method is not only cumbersome and inefficient, but the frequent tightening of the screws can also easily cause wear and cracking of the plastic support, affecting the stability and lifespan of the instrument.

[0039] The consistency measuring instrument 100 of this utility model embodiment has a simple structure and is easy to operate. By setting a locking structure with a pin 5, the measuring component 2 can be quickly released and locked by plugging and unplugging, avoiding structural damage caused by repeated screw tightening, and improving ease of use and reliability.

[0040] The slide bar 21 is equipped with a scale line 23 for direct reading, which, in conjunction with the reference surface on the fixed rod 4, facilitates accurate zeroing and intuitive reading of the sinking depth. The drive assembly 3 automatically controls the extension and retraction of the pull rope 32, enabling automatic release and rapid reset of the measuring component 2, eliminating the need for manual operation and improving testing efficiency and repeatability. The consistency measuring instrument 100 of this embodiment simplifies and automates the testing process, significantly improving the instrument's practicality, durability, and measurement accuracy.

[0041] It should be noted that the speed at which the drive unit 31 releases the pull rope 32 is greater than the speed at which the measuring component 2 falls freely. Moreover, when the measuring component 2 is inserted into the bottom of the slurry container 11, the distance it falls is L1, and the length of the pull rope 32 released by the drive unit 31 is L2. L2 is greater than L1, so it will not interfere with the fall of the measuring component 2.

[0042] In some embodiments, the drive element 31 is a motor, which includes a body 311, an output shaft 312, and a stop block 313.

[0043] The pull rope 32 is wound around the output shaft 312. The stop block 313 is provided at the end of the output shaft 312, and the cross-sectional area of ​​the stop block 313 is larger than the cross-sectional area of ​​the output shaft 312.

[0044] In this embodiment, the motor serves as the power source for the drive assembly 3. Its body 311 is fixed on the frame 1, and the output shaft 312 is used to wind the pull rope 32. By rotating forward or backward, the pull rope 32 is released and retracted, thereby driving the slide bar 21 to move up and down. The stop block 313 is located at the end of the output shaft 312 and has a cross-sectional area larger than the output shaft 312 itself. It can play a limiting role during the winding of the pull rope 32, preventing the pull rope 32 from slipping off the end of the output shaft 312 and ensuring the stability of the transmission.

[0045] The consistency measuring instrument 100 of this utility model constrains the position of the pull rope 32 by setting a stop 313 at the end of the output shaft 312, thereby reducing operational failures caused by the pull rope 32 deviating or coming off, and improving the reliability and service life of the drive component 3.

[0046] In some embodiments, the frame 1 includes a base 12 and a support rod 13.

[0047] The base 12 is equipped with a fixing element to secure the slurry container 11.

[0048] The support rod 13 is fixedly connected to the base 12 and extends along the first direction. The fixed rod 4 and the driving component 31 are both connected to the support rod 13.

[0049] In this embodiment, the base 12 is used to support the entire component and keep it stable, and the fixing member on it can position the slurry container 11 to avoid the slurry container 11 moving during the test and affecting the results.

[0050] The support rod 13 is vertically connected to the base 12, serving as the main load-bearing frame and providing an installation position for the fixing rod 4 and the driving component 31, ensuring that the relative positions of each functional component are accurate and the assembly is firm.

[0051] In some embodiments, the fixing rod 4 includes a mounting hole, a threaded hole, and a set screw 41.

[0052] The mounting hole is fitted onto the support rod 13. The mounting hole extends in the vertical direction.

[0053] The threaded hole is connected to the mounting hole, and the axis of the threaded hole is perpendicular to the axis of the mounting hole.

[0054] Set screw 41 mates with threaded hole.

[0055] In this embodiment, the fixing rod 4 is sleeved on the support rod 13 through the mounting hole, and its height position can be adjusted along the axial direction of the support rod 13.

[0056] After adjustment, tighten the set screw 41 so that it passes through the threaded hole and presses against the surface of the support rod 13, thereby achieving the locking and positioning of the fixing rod 4; the threaded hole is set perpendicular to the mounting hole, which facilitates the application of force for locking and has a compact structure.

[0057] The consistency measuring instrument 100 of this utility model has an adjustable fixing rod 4 mounting structure, which allows the height of the guide hole and the reference surface to be adjusted according to actual use needs, so as to adapt to different test conditions.

[0058] In some embodiments, the drive assembly 3 includes a start switch disposed on the base 12. The start switch is used to control the drive component 31 to rotate in a preset direction to release the measuring component 2.

[0059] In this embodiment, the start switch is arranged on the base 12. The operator can easily touch the switch during the test to trigger the drive component 31 (such as a motor) to rotate in the set direction, so that the pull rope 32 is released. After the pin 5 is pulled out, the measuring component 2 is automatically released, which simplifies the test start process.

[0060] The consistency measuring instrument 100 of this utility model embodiment directly controls the release action of the measuring element 2 by setting a start switch, which makes the operation convenient.

[0061] In some embodiments, the drive assembly 3 includes a reset switch disposed on the base 12. The reset switch is used to control the drive component 31 to rotate in a direction opposite to a preset direction, thereby resetting the measuring component 2.

[0062] In this embodiment, the reset switch is used in conjunction with the start switch. When pressed, the drive unit 31 is controlled to rotate in reverse, rewinding the pull rope 32 and pulling the slide bar 21 and the test cone 22 back to the initial position, completing the automatic reset without the need for manual pulling, thus improving the operating efficiency.

[0063] The consistency measuring instrument 100 of this utility model realizes the automatic return of the measuring component 2 by setting a reset switch, which avoids the problems of uneven force or inaccurate position caused by manual reset and ensures the consistency of the starting state of each test.

[0064] In some embodiments, the frame 1 is provided with a guide wheel, which is located between the drive member 31 and the slide rod 21 and is located on the path of the pull rope 32. The pull rope 32 is wound in the groove of the guide wheel and is slidably in contact with the guide wheel.

[0065] In this embodiment, the guide wheel is installed in the transmission path of the pull rope 32, and the pull rope 32 slides in its wheel groove, changing the direction of force on the pull rope 32, so that it connects the drive component 31 and the slide rod 21 more smoothly, reducing the friction and uneven wear between the pull rope 32 and the bracket, and ensuring smooth transmission of traction force.

[0066] The consistency measuring instrument 100 of this utility model optimizes the routing path of the pull rope 32 by setting a guide wheel, which reduces motion resistance, slows down the wear of the pull rope 32, and improves the stability of the drive response and transmission efficiency.

[0067] In some embodiments, the fixed rod 4 is provided with a light lamp, which is positioned toward the scale line 23 to provide illumination when taking readings.

[0068] In this embodiment, the lighting lamp is installed on the fixed rod 4, and the light emission direction is aligned with the scale line 23 on the slide rod 21. It is turned on when the ambient light is insufficient to enhance the visibility of the scale markings and make it easier for the operator to clearly read the sinking depth of the test cone 22.

[0069] The consistency measuring instrument 100 of this utility model improves reading conditions, reduces reading deviations caused by visual errors, and enhances the objectivity of measurement results by integrating an illumination function into the fixed rod 4.

[0070] In some embodiments, the side wall of the slurry container 11 is marked with capacity graduation lines 23.

[0071] In this embodiment, the capacity scale line 23 is directly marked on the side wall of the slurry container 11 to indicate the volume or height of the slurry in the container. This can help control the amount of slurry filled during loading and ensure that the volume of slurry used in each test is consistent.

[0072] The consistency measuring instrument 100 of this utility model realizes the visual control of mortar usage by setting the capacity scale line 23 in the mortar container 11, which helps to maintain the uniformity of test conditions and improve the accuracy of test results.

[0073] In some embodiments, the support rod 13 is a telescopic rod.

[0074] In this embodiment, the support rod 13 adopts a telescopic structure, which can adjust the overall height, thereby driving the fixed rod 4, drive component 31 and other components to rise and fall synchronously, adapting to the installation and operation needs of different specifications or usage scenarios.

[0075] The consistency measuring instrument 100 of this utility model adopts a telescopic support rod 13, which enhances the structural adaptability of the instrument, facilitates the adjustment of the equipment height on different work surfaces or in transportation conditions, and improves the flexibility of use.

[0076] Optionally, the number of revolutions of the drive unit 31 in either forward or reverse direction is preset by a program.

[0077] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
