Description

Technical Field

[0001] This utility model relates to the field of mortar consistency testing technology, specifically a mortar consistency testing device. Background Technology

[0002] The mortar consistency testing device is an instrument used to determine the flowability of mortar. It mainly consists of a cone with a sliding rod and a truncated conical metal hopper. The mixed mortar is loaded into the hopper in one go until it is about 1 cm from the top of the hopper. It is then compacted according to the specified test method and tested with a mortar consistency meter.

[0003] Currently, in the existing technology, for example, Chinese patent with announcement number CN218067542U discloses a mortar consistency testing device. This device can connect to a measuring ruler through a connecting hole set on the top of the round rod. The clamping device can clamp the support rod with the first frame. The marking block and the measuring ruler can record the point when the test cone is fixed and the point when the test cone is lowered. The difference between the two points is the value to be tested, which shows its practicality in mortar consistency testing.

[0004] However, in practical applications, this device still exhibits certain operational limitations and accuracy issues. Specifically, when releasing the test cone, the operator must manually loosen the bolt to release the constraint on the rod, allowing the cone to fall freely. However, this process presents a potential problem: as the bolt gradually loosens, the rod may experience premature, slight slippage due to the release of preload, which is particularly noticeable under gravity. More importantly, this initial, uncontrolled slippage is often difficult to accurately capture or predict, occurring before the bolt is completely detached from the rod, potentially leading to a deviation between the actual initial drop position and the theoretical position. Once the bolt is completely released from its constraint, the rod continues to fall as expected, but due to the previous unexpected slippage, this error factor inevitably becomes part of the final test value. Therefore, a mortar consistency testing device is proposed. Utility Model Content

[0005] The main objective of this invention is to provide a mortar consistency testing device that can solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention proposes a mortar consistency testing device, comprising a base, a placement seat fixedly connected to the upper side of the base, a mortar bucket placed on the placement seat, and a support assembly, a testing assembly, a positioning assembly, and a measuring ruler disposed above the base. The positioning assembly includes:

[0007] A sleeve, wherein a round rod is fitted onto the sleeve, and the round rod is elastically connected to the inner wall of the sleeve by a return spring;

[0008] A button is rotatably connected to the end of a round rod away from the inner wall of the sleeve. A hinge rod is hinged to the outer wall of the round rod, and a connecting block is hinged to the end of the hinge rod away from the round rod.

[0009] And a limiting rod, the limiting rod being fixedly connected to the outer wall of the connecting block, and the end of the limiting rod away from the connecting block being wedge-shaped.

[0010] Preferably, a positioning rod is fixedly connected to the side of the button near the sleeve. A positioning opening is provided on the outer wall of the sleeve, and a positioning block is fixedly connected to the outer wall of the sleeve. By rotating the button, the positioning rod is driven to rotate to the positioning block limit position. Then, by pressing the button, the positioning rod can be inserted into the positioning opening, realizing the movement of the round rod in the sleeve. The compression of the return spring causes the hinge rod to drive the connecting block to move, thereby driving the limit rod to move.

[0011] Preferably, the support assembly includes a vertical rod, on which a first support and a second support are detachably connected by bolts.

[0012] Preferably, the limiting rod passes through the bracket and is slidably connected to the bracket, and the sleeve is fixedly connected to the outer wall of the bracket.

[0013] Preferably, the detection component includes a rod, a test cone is fixedly connected to the bottom of the rod, a slot is provided on the outer wall of the rod, and a fixing block is fixedly connected to the top of the rod. When the limiting rod is inserted into the slot, the rod is stably fixed. When the limiting rod is removed from the slot, the limiting of the rod is released, enabling free fall motion.

[0014] Preferably, the rod passes through bracket one and is slidably connected to bracket one, the measuring ruler passes through bracket two and is slidably connected to bracket two, and a clamping bolt is threaded on bracket two, and the measuring ruler is clamped by rotating the clamping bolt.

[0015] This invention provides a mortar consistency testing device. It has the following advantages:

[0016] (1) The mortar consistency testing device uses a positioning component, which allows the device to release the limit rod from the bayonet when testing the consistency of the mortar, thereby allowing the rod and the test cone to fall freely. This prevents the actual starting position of the round rod from deviating from the theoretical position, thus improving the accuracy of the measurement results.

[0017] (2) With the use of the positioning component, when the limit rod needs to be disengaged from the bayonet, the button must be turned first so that the positioning rod is driven to rotate to the positioning block limit. Then the button is pressed so that the positioning rod can be inserted into the positioning port, so that the round rod can move in the sleeve. This prevents the staff from accidentally pressing the button during the mortar consistency testing operation, thus achieving the effect of preventing accidental touch. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figures 1-6 This utility model proposes a mortar consistency testing device, including a base 1, a placement seat 2 fixedly connected to the upper side of the base 1, a mortar bucket 3 placed on the placement seat 2, and a support assembly 4, a testing assembly 5, a positioning assembly 6 and a measuring ruler 7 arranged above the base 1. The support assembly 4 includes a vertical rod 41, and a first support 42 and a second support 43 are detachably connected to the vertical rod 41 by bolts.

[0030] In this embodiment of the present invention, in order to detect the consistency of mortar in the mortar bucket 3, the detection component 5 specifically includes a rod 51, a test cone 53 fixedly connected to the bottom of the rod 51, a slot 52 opened on the outer wall of the rod 51, a fixing block 54 fixedly connected to the top of the rod 51, the rod 51 passing through the first bracket 42 and slidably connected to the first bracket 42, and a measuring ruler 7 passing through the second bracket 43 and slidably connected to the second bracket 43. A clamping bolt is threaded on the second bracket 43. By rotating the clamping bolt, the measuring ruler 7 is clamped. After the mortar bucket 3 filled with mortar is placed on the placement seat 2, the free fall motion of the rod 51 and the test cone 53 allows the test cone 53 to fall into the mortar. Then, by rotating the clamping bolt, the measuring ruler 7 is moved to contact the fixing block 54, and the detected value can be measured. This is the prior art, which is described in detail in Chinese Patent No. CN218067542U. This present invention will not elaborate further.

[0031] Furthermore, to improve the accuracy of the detection results, the positioning component 6 specifically includes a sleeve 61, a button 63, and a limiting rod 66. A round rod 62 is fitted onto the sleeve 61, and the round rod 62 is elastically connected to the inner wall of the sleeve 61 via a return spring. The button 63 is rotatably connected to the end of the round rod 62 away from the inner wall of the sleeve 61. A hinge rod 64 is hinged to the outer wall of the round rod 62, and a connecting block 65 is hinged to the end of the hinge rod 64 away from the round rod 62. The limiting rod 66 is fixedly connected to the outer wall of the connecting block 65, and the end of the limiting rod 66 away from the connecting block 65 is wedge-shaped. The limiting rod 66 penetrates the bracket. The sleeve 61 is fixedly connected to the outer wall of the support 42 and the connecting block 65 is elastically connected to the outer wall of the support 42 through a connecting spring. When the button 63 is pressed, the round rod 62 moves and the reset spring is compressed. During this process, the hinge rod 64 moves, which in turn moves the connecting block 65, stretches the connecting spring, and makes the limiting rod 66 move away from the bayonet 52, thereby releasing the limitation on the rod 51. This allows the rod 51 and the test cone 53 to fall freely, preventing any deviation between the actual starting position and the theoretical position of the round rod 62, thus improving the accuracy of the measurement results.

[0032] Furthermore, a positioning rod 631 is fixedly connected to the side of button 63 near sleeve 61. A positioning port 611 is opened on the outer wall of sleeve 61, and a positioning block 612 is fixedly connected to the outer wall of sleeve 61. When it is necessary to disengage the limiting rod 66 from the bayonet 52, button 63 must be rotated first to drive the positioning rod 631 to rotate to the positioning block 612 limit. Then, button 63 is pressed, and the positioning rod 631 can be inserted into the positioning port 611, so that the round rod 62 can move in sleeve 61. This two-step operation design effectively prevents the staff from accidentally squeezing button 63 due to accidental touch or improper operation during mortar consistency testing, which would cause the device to act prematurely or malfunction. This achieves a true anti-accidental touch effect and improves the overall stability of operation.

[0033] It should be noted that the above electrical components are all existing technology products. Those skilled in the art should select, install and complete the circuit debugging work according to the needs of use to ensure that all electrical appliances can work normally. The components are all general standard parts or components known to those skilled in the art. Their structure and principle can be known by those skilled in the art through technical manuals or conventional experimental methods. No specific restrictions are made here.

[0034] In use, first place the mortar bucket 3 filled with mortar on the placement seat 2, then turn the button 63 to drive the positioning rod 631 to rotate to the positioning block 612 limit. Then press the button 63 again, and the positioning rod 631 can be inserted into the positioning port 611, driving the round rod 62 to move. During the compression of the return spring, the hinge rod 64 moves, which in turn drives the connecting block 65 to move, stretching the connecting spring, so that the limit rod 66 moves away from the bayonet 52, thereby releasing the limit on the rod body 51, and allowing the rod body 51 and the test cone 53 to fall freely, so that the test cone 53 can fall into the mortar. Then, by turning the clamping bolt, the measuring ruler 7 moves to contact the fixed block 54, and the test value can be measured.

[0035] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
