[0024] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0025] Reference Figure 1-3 The embodiment of the utility model provides a mortar stratification meter with an easy-to-assemble and disassemble stratification cylinder, comprising an upper section cylinder 1 and a lower section cylinder 2, one of which is rotatably connected to a pair of threaded rods 3, and the other of the lower section cylinder 2 and the upper section cylinder 1 is correspondingly provided with an annular groove 5, a threaded sleeve 31 is threadedly sleeved on the threaded rod 3, and the end of the threaded sleeve 31 facing away from the threaded rod 3 is rotatably connected to a pull rod 4.

[0026] Specifically, a threaded rod 3 is rotatably connected to the lower section cylinder 2, and an annular groove 5 is opened on the upper section cylinder 1. After the upper section cylinder 1 and the lower section cylinder 2 are clamped, the threaded rod 3 is rotated until the pull rod 4 at one end of the threaded rod 3 extends into the annular groove 5. At this time, the threaded rod 3 is rotated to move away from the annular groove 5, and the threaded rod 3 pulls the pull rod 4 and simultaneously pulls the upper section cylinder 1 to lock the upper section cylinder 1 on the lower section cylinder 2. Then an experiment is carried out. After 30 minutes of the experiment, the threaded rod 3 is rotated in the opposite direction to extend the pull rod 4. Since the pull rod 4 is stuck In the annular groove 5, the pull rod 4 pushes against the annular groove 5 to lift the upper section tube 1. When the upper section tube 1 and the lower section tube 2 become loose, the threaded rod 3 is rotated to make the pull rod 4 leave the annular groove 5. At this time, the upper section tube 1 can be removed. The utility model provides a mortar stratification meter with easy disassembly and assembly of the stratification tube. The upper section tube 1 and the lower section tube 2 can be tightened and fixed by pulling against the threaded sleeve 31 and the pull rod 4, and the upper section tube 1 and the lower section tube 2 can be stretched and separated, which is convenient for connection and disassembly of the upper section tube 1 and the lower section tube 2 and is easy to use.

[0027] In another embodiment provided by the utility model, a sealing ring 6 is provided between the upper section tube 1 and the lower section tube 2, the inner diameter of the sealing ring 6 is the same as the outer diameter of the upper section tube 1 and the lower section tube 2, and an annular gasket 7 is provided on the inner wall of the sealing ring 6. Specifically, the sealing ring 6 is put on the lower section tube 2 until the upper end surface of the lower section tube 2 contacts the annular gasket 7, and then the upper section tube 1 is inserted into the sealing ring 6 and contacts the side of the annular gasket 7 facing away from the lower section tube 2 to complete the sealing.

[0028] In another embodiment provided by the utility model, two supports 8 are provided on the outer wall of the lower section cylinder 2, and the two threaded rods 3 are rotatably connected to the supports 8 respectively. A connecting rod is fixed at one end of the threaded rod 3, and the connecting rod is perpendicular to the threaded rod 3. The threaded rod 3 is rotatably connected to the support 8 through the connecting rod.

[0029] In another embodiment provided by the utility model, two annular partitions 9 are spaced apart on the upper section cylinder 1 , and an annular groove 5 is formed between the two annular partitions 9 .

[0030] In another embodiment provided by the utility model, a handle is sleeved on the threaded sleeve 31, and the handle is convenient for rotating the threaded sleeve 31.

[0031] In another embodiment provided by the utility model, a marking groove 12 is provided on the threaded rod 3. Since the threaded sleeve 31 rotates on the threaded rod 3 after each experiment and its position is uncertain, in the next experiment, after the upper section cylinder 1 and the lower section cylinder 2 are clamped, the pull rod 4 cannot accurately align with the annular clamping groove 5 when the threaded rod 3 rotates. Therefore, the marking groove 12 is provided at a specific position on the threaded rod 3 so that when the threaded sleeve 31 is rotated to the position of the marking groove 12, the end of the pull rod 4 away from the threaded sleeve 31 is just in the marking groove 12. After each use, the threaded sleeve 31 can be rotated back to the position of the marking groove 12.

[0032] In another embodiment provided by the utility model, the pull rod 4 is an L-shaped rod, the vertical section of the L-shaped rod is a threaded section, the vertical section of the L-shaped rod is threadedly connected to the threaded sleeve 31, and the horizontal section of the L-shaped rod is perpendicular to the threaded sleeve 31. When the threaded sleeve 31 and the threaded rod 3 are rotated to a vertical state together, the horizontal section of the L-shaped rod is just inserted into the annular groove 5. When the L-shaped rod moves downward with the rotation of the threaded sleeve 31, the L-shaped rod pulls the upper section cylinder 1 downward to lock the lower section cylinder 2. When the L-shaped rod moves upward with the rotation of the threaded sleeve 31, the L-shaped rod pushes the upper section cylinder 1 upward to separate the upper section cylinder 1 from the lower section cylinder 2.

[0033] In another embodiment provided by the utility model, a magnetic attraction part is fixed on the upper section cylinder 1, and the magnetic attraction part is arranged between the annular partition plates 9. After the upper section cylinder 1 and the lower section cylinder 2 are clamped by the sealing ring 6, the threaded rod 3 is rotated and lifted to insert the L-shaped rod into the annular groove 5. The L-shaped rod is attracted and positioned by the magnetic attraction part in the annular groove 5. At this time, the threaded sleeve 31 can be rotated to fix and tighten.

[0034] In another embodiment provided by the utility model, three supporting feet 14 are provided at the bottom of the lower section cylinder 2, and the supporting feet 14 are retractable. A spirit level is provided on the lower section cylinder 2. In order to prevent the lower section cylinder 2 from being placed in an uneven position and affecting the experiment, it can be leveled by adjusting the length of the supporting feet 14 and observing the spirit level.

[0035] In another embodiment of the present invention, a threaded column 16 is fixed to the bottom of the lower section cylinder 2, and the support leg 14 is threadedly connected to the threaded column 16. The length of the support leg 14 can be adjusted by rotating the support leg 14 to move on the threaded column 16.

[0036] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
