Description

Technical Field

[0001] This utility model relates to the field of mortar testing technology, and in particular to a mortar segregation measuring cylinder. Background Technology

[0002] Mortar is a common building material, and its water retention performance needs to be tested before use. The water retention of mortar is determined by segregation. The test method is to put the mortar into a specified container and measure its sinking depth; after standing for 30 minutes, take the mortar from the bottom 1 / 3 of the container and measure its sinking depth again; the difference between the two sinking depths is the segregation degree, which is measured in mm. The greater the segregation degree, the worse the water retention of the mortar.

[0003] Existing mortar segregation degree testers consist of an upper segregation degree cylinder and a lower segregation degree cylinder connected by bolts. When measuring segregation degree, the first penetration parameter is measured from the upper segregation degree cylinder, and the second penetration parameter is measured from the lower segregation degree cylinder. Since measuring the penetration in the lower segregation degree cylinder requires opening the upper segregation degree cylinder, the bolts connecting the upper and lower segregation degree cylinders need to be disassembled and reassembled after the measurement is completed. The operation steps are cumbersome, making the mortar segregation degree tester inconvenient to use and affecting the efficiency of the testing work. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a mortar segregation degree measuring cylinder, which solves the problem of cumbersome disassembly and assembly procedures in existing mortar segregation degree measuring instruments.

[0005] According to an embodiment of the present invention, a mortar segregation measuring cylinder includes a lower indexing cylinder and an upper indexing cylinder detachably disposed on the top of the lower indexing cylinder. The lower indexing cylinder has a first protrusion at one end near the upper indexing cylinder, and the upper indexing cylinder has a second protrusion that fits against the first protrusion. The cylinder also includes a connector, which includes a connecting buckle. One end of the connecting buckle is rotatably connected to a first connecting arm, and the other end is rotatably connected to a second connecting arm. The connecting buckle, the first connecting arm, and the second connecting arm form a ring and surround the first and second protrusions, fixing their relative positions. The end of the first connecting arm away from the connecting buckle has a movable block and a spring that abuts against the movable block. The movable block is located on the side of the first connecting arm away from the second connecting arm and has a hook. The first connecting arm has a first slot for the hook to pass through, and the second connecting arm has a second slot aligned with the first slot. The side of the second connecting arm away from the first connecting arm has a slot that engages with the hook. The spring drives the movable block to move in the direction that allows the hook to extend into the slot.

[0006] Furthermore, the second boss is provided with a protruding positioning ring, and the first boss is provided with a positioning groove that cooperates with the positioning ring.

[0007] Furthermore, a sealing ring is provided in the positioning groove, and the sealing ring is arranged around the positioning ring.

[0008] Furthermore, each end of the connecting buckle is provided with a mounting rod, and the first connecting arm and the second connecting arm are respectively provided with mounting holes that cooperate with the mounting rods.

[0009] Furthermore, the connecting buckle, the first connecting arm, and the second connecting arm are respectively provided with grooves, and the first boss and the second boss extend into the grooves respectively.

[0010] Furthermore, the first connecting arm is provided with a sliding groove, the movable block is movably disposed in the sliding groove, and the sliding groove is connected to the first slot.

[0011] Furthermore, the first connecting arm is provided with a guide hole, the axial direction of which is consistent with the moving direction of the movable block and communicates with the slide groove. The movable block is provided with a guide rod that cooperates with the guide hole, one end of which extends out of the slide groove and the spring is sleeved on the guide rod.

[0012] Furthermore, the first connecting arm is also provided with a detachable cover plate, which covers the opening of the slot.

[0013] Furthermore, the hook has a wedge-shaped portion, and the slot has a guide surface that fits into the wedge-shaped portion.

[0014] Furthermore, the lower indexing cylinder is also provided with a base, which is located at the bottom of the lower indexing cylinder.

[0015] Compared with the prior art, this utility model has the following advantages: By setting a first protrusion on the lower indexing cylinder and a second protrusion that fits against the first protrusion on the upper indexing cylinder, and using a connector to fix the relative positions of the first and second protrusions, the connector includes a connecting buckle and a first connecting arm and a second connecting arm at both ends of the connecting buckle. By forming a ring with the connecting buckle, the first connecting arm, and the second connecting arm to hold the first and second protrusions tightly, the upper indexing cylinder can be fixed on the lower indexing cylinder. When using the connector to fix the upper and lower indexing cylinders, the hook on the first connecting arm is first passed through the hook on the second connecting arm. The second slot is then opened, and the movable block is moved to allow the hook to extend into the slot and engage with it. The spring force keeps the hook in the slot, thus keeping the connector in a ring-shaped state. When the upper indexing cylinder needs to be removed from the lower indexing cylinder, the movable block is moved and the first connecting arm and / or the second connecting arm are rotated to allow the hook to exit the slot and the second slot in sequence, thus removing the connector and separating the upper indexing cylinder from the lower indexing cylinder. This solves the technical problem of cumbersome disassembly and assembly procedures in existing mortar segregation testers, and simplifies the operation steps when assembling or disassembling the upper and lower indexing cylinders, improving testing efficiency.

[0022] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0023] like Figures 1 to 5 As shown in the figure, this utility model embodiment proposes a mortar segregation measuring cylinder for testing the water retention performance of mortar.

[0024] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 The mortar segregation measuring cylinder includes a lower indexing cylinder 1 and an upper indexing cylinder 2 detachably mounted on top of the lower indexing cylinder 1. The lower indexing cylinder 1 has a first protrusion 11 at one end near the upper indexing cylinder 2, and the upper indexing cylinder 2 has a second protrusion 21 that fits against the first protrusion 11. The mortar segregation measuring cylinder also includes a connector, which includes a connecting buckle 3. One end of the connecting buckle 3 is rotatably connected to a first connecting arm 4, and the other end is rotatably connected to a second connecting arm 5. The connecting buckle 3, the first connecting arm 4, and the second connecting arm 5 form a ring and encircle the first protrusion 11 and the second protrusion 21, fixing their relative positions. The end of the first connecting arm 4 away from the connecting buckle 3 has a movable block 6 and a spring 7 that abuts against the movable block 6. The movable block 6 is located at the end of the first connecting arm 4 away from the connecting buckle 3. On one side away from the second connecting arm 5, the movable block 6 has a hook 61. The first connecting arm 4 has a first slot 41 through which the hook 61 passes, and the second connecting arm 5 has a second slot 51 aligned with the first slot 41. On the side of the second connecting arm 5 away from the first connecting arm 4, there is a slot 52 that mates with the hook 61. The spring 7 drives the movable block 6 to move in the direction that allows the hook 61 to extend into the slot, so that the connecting member can be kept in a ring shape and wrapped around the first boss 11 and the second boss 21 by the elastic force provided by the spring 7.

[0025] Specifically, the assembly and disassembly steps of the mortar segregation measuring cylinder provided in this embodiment are as follows: When installing the upper indexing cylinder 2 onto the lower indexing cylinder 1, first place the upper indexing cylinder 2 onto the lower indexing cylinder 1 and make the second protrusion 21 fit with the first protrusion 11. Then, fit the connecting buckle 3 with the first protrusion 11 and the second protrusion 21 and rotate the first connecting arm 4 and the second connecting arm 5 to form a ring around the connector, so that the connector surrounds the first protrusion 11 and the second protrusion 21. Then, pass the hook 61 through the second slot 51 and move the movable block 6 so that the hook 61 extends into the slot 52 and... When the slot 52 engages, the connector clamps the first boss 11 and the second boss 21 to fix the upper indexing cylinder 2 onto the lower indexing cylinder 1. The spring 7 provides elasticity to keep the hook 61 within the slot 52 so that the connector remains in a ring-shaped state. When it is necessary to remove the upper indexing cylinder 2 from the lower indexing cylinder 1, first move the movable block 6 to make the hook 61 exit the slot 52, then rotate the first connecting arm 4 and / or the second connecting arm 5 to make the hook 61 exit the second slot 51. At this time, the connector can be removed and the upper indexing cylinder 2 can be separated from the lower indexing cylinder 1. The mortar segregation measuring cylinder provided in this embodiment achieves the combination and disassembly of the upper indexing cylinder 2 and the lower indexing cylinder 1 by moving the movable block 6 and rotating the first connecting arm 4 and the second connecting arm 5. This simplifies the operation steps when the upper indexing cylinder 2 is installed on the lower indexing cylinder 1 or when the upper indexing cylinder 2 is removed from the lower indexing cylinder 1. The operation is simple and helps to improve the detection efficiency of mortar.

[0026] like Figure 2 As shown, the second boss 21 is provided with a protruding positioning ring 22, and the first boss 11 is provided with a positioning groove that cooperates with the positioning ring 22. The upper indexing cylinder 2 and the lower indexing cylinder 1 are positioned by the cooperation of the positioning ring 22 and the positioning groove. When the upper indexing cylinder 2 is installed onto the lower indexing cylinder 1, the positioning ring 22 is inserted into the positioning groove, which facilitates the assembly of the mortar segregation measuring cylinder and ensures that the upper indexing cylinder 2 and the lower indexing cylinder 1 are aligned.

[0027] Specifically, a sealing ring 12 is provided in the positioning groove, and the sealing ring 12 surrounds the positioning ring 22. By providing the sealing ring 12 in the positioning groove, when the positioning ring 22 is inserted into the positioning groove, the sealing ring 12 surrounds the positioning ring 22 to improve the sealing between the upper indexing cylinder 2 and the lower indexing cylinder 1, preventing mortar leakage between the upper indexing cylinder 2 and the lower indexing cylinder 1 during the testing process.

[0028] Please combine Figure 2 , Figure 4 and Figure 5 The connecting buckle 3 has mounting rods 31 at both ends, and the first connecting arm 4 and the second connecting arm 5 are respectively provided with mounting holes 53 that cooperate with the mounting rods 31. The first connecting arm 4 and the second connecting arm 5 are respectively installed onto the connecting buckle 3 through the mounting holes 53 and the corresponding mounting rods 31, ensuring the structural stability of the connector and allowing the first connecting arm 4 and the second connecting arm 5 to rotate smoothly relative to the connecting buckle 3.

[0029] In this embodiment, the connecting buckle 3, the first connecting arm 4, and the second connecting arm 5 are respectively provided with grooves 32, and the first boss 11 and the second boss 21 extend into the grooves 32. The grooves 32 are used to accommodate the first boss 11 and the second boss 21 when the connecting member clamps the first boss 11 and the second boss 21, thereby improving the stability of the connection between the connecting member and the upper indexing cylinder 2 and the lower indexing cylinder 1, preventing the connecting member from separating from the upper indexing cylinder 2 or the lower indexing cylinder 1 during the detection process, and by covering the gap between the first boss 11 and the second boss 21 by the connecting member, the sealing performance of the mortar segregation degree measuring cylinder can be further improved, making the mortar segregation degree measuring cylinder more reliable.

[0030] Such as 3 and Figure 5 As shown, the first connecting arm 4 is provided with a sliding groove 42, and the movable block 6 is movably disposed within the sliding groove 42, with the sliding groove 42 communicating with the first slot 41. The sliding groove 42 on the first connecting arm 4 allows the movable block 6 to move smoothly on the first connecting arm 4 while preventing it from deviating from a preset direction, thus improving the stability of the movable block 6 during movement.

[0031] Specifically, the first connecting arm 4 is provided with a guide hole 43, the axial direction of the guide hole 43 is consistent with the moving direction of the movable block 6 and communicates with the slide groove 42, the movable block 6 is provided with a guide rod 62 that cooperates with the guide hole 43, one end of the guide rod 62 extends out of the slide groove 42 and the spring 7 is sleeved on the guide rod 62. The guide hole 43 is provided on the first connecting arm 4 and the guide rod 62 is provided on the movable block 6. When the movable block 6 moves, the guide rod 62 slides in the guide hole 43 to ensure that the movable block 6 and the first connecting arm 4 are stably engaged. One end of the guide rod 62 extends out of the slide groove 42 and the spring 7 is sleeved on the guide rod 62 to facilitate the movement of the movable block 6. By pressing the guide rod 62 to extend out of the slide groove 42, the movable block 6 can move in the slide groove 42. When the guide rod 62 is pressed, the hook 61 moves in the direction of exiting the slot 52 and further compresses the spring 7. At this time, the hook 61 can pass through the second slot 51 to wrap the connector around the first boss 11 and the second boss 21 or to remove the connector. After releasing the guide rod 62, the spring 7 returns to its original length and pushes the movable block 6 to move, so that the hook 61 can automatically extend into the slot, which facilitates the assembly and disassembly of the connector.

[0032] Please refer to Figure 5 The first connecting arm 4 is also provided with a detachable cover plate 8, which covers the opening of the slot. The cover plate 8 is used to cover the opening of the slot to close the slot, so that the movable block 6 and the spring 7 are held in the slide groove 42, preventing mortar from falling into the slot during the detection process and hindering the movement of the movable block 6, thereby extending the service life of the mortar segregation measuring cylinder.

[0033] Please combine Figure 3 and Figure 4 The hook 61 has a wedge-shaped portion 63, and the slot 52 has a guide surface 54 that fits against the wedge-shaped portion 63. When the hook 61 moves, the wedge-shaped portion 63 extends into the slot 52 and engages with it. The guide surface 54 that fits against the wedge-shaped portion 63 is provided in the slot 52. As the wedge-shaped portion 63 enters the slot 52, it pulls the two ends of the first connecting arm 4 and the second connecting arm 5 closer together, thereby ensuring that the connector tightly holds the first boss 11 and the second boss 21.

[0034] like Figure 1 and Figure 2As shown, in this embodiment, the lower indexing cylinder 1 is further provided with a base 13, which is located at the bottom of the lower indexing cylinder 1. By setting the base 13 at the bottom of the lower indexing cylinder 1, the lower indexing cylinder 1 can stand stably on the working surface, preventing the mortar segregation measuring cylinder from tipping over during the testing process.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
