Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further specifically described below by way of embodiments and with reference to the accompanying drawings.

Example 1

Referring to fig. 1-3, the concrete impermeability tester of the embodiment includes a workbench (not shown in the figures), and a plurality of sets of a mold base 1 and a mold cylinder 2, which are disposed on the surface of the workbench, wherein the mold cylinder 2 is detachably mounted on the mold base 1 to form a test mold for testing impermeability of concrete. Specifically, a circular groove matched with the die cylinder 2 is formed in the surface of the die holder 1 and used for placing the die cylinder 2.

In this embodiment, four clamping legs 21 are uniformly arranged on the bottom edge of the die cylinder 2 along the circumferential direction, and the thickness of one end of each clamping leg 21 is gradually increased inwards to form a wedge-shaped end portion 22, so as to be inserted into a second clamping groove 12; the wedge-shaped ends 22 of the four catches 21 all face in the same direction in the circumferential direction of the die cylinder 2.

Four first clamping grooves 11 which are correspondingly matched with the clamping pins 21 are formed in the die holder 1 along the circumferential direction of the circular groove, and the top of each first clamping groove 11 is opened, so that the clamping pins 21 can be embedded into the first clamping grooves 11 from the upper part; one side of the first clamping groove 11 corresponding to the wedge-shaped end 22 of the clamping leg extends inwards along the circumferential direction to form a second clamping groove 12, the height of the second clamping groove 12 is matched with the maximum thickness of the clamping leg 21, and the length of the second clamping groove 12 is equal to that of the clamping leg 21. After the clamping pin 21 is embedded into the first clamping groove 11, the clamping pin 21 can be inserted into the second clamping groove 12 by rotating the die cylinder 2, so that the vertical freedom degree of the die cylinder 2 relative to the die holder 1 is limited.

In the specific implementation of this embodiment, the assembly is completed only by aligning the clamping pin 21 of the die cylinder 2 with the position of the first clamping groove 1 on the die holder 1 and embedding the same therein, and then rotating the die cylinder 2 to clamp the clamping pin 21 in the second clamping groove 12; when the die cylinder 2 is disassembled, the clamping pins 21 are separated from the second clamping grooves 12 by reversely rotating the die cylinder 2, and the die cylinder 2 can be upwards taken up to complete the disassembly.

Example 2

Referring to fig. 4, the present embodiment is different from embodiment 1 only in that the present embodiment adds a rotational degree of freedom restriction mechanism to embodiment 1. In this embodiment, a movable stop block 3 is disposed on one side of the first card slot 11 away from the second card slot 12, the movable stop block 3 is hinged to an opening of the first card slot 11 away from the second card slot 12, and the length of the movable stop block 3 is equal to that of the first card slot 11. After the die cylinder 2 is assembled, the movable stop block 3 is turned and embedded into the first clamping groove 11, and the movable stop block 3 blocks the clamping leg 21, so that the circumferential rotation freedom degree of the die cylinder 2 is limited.

In the above structure, a lifting rope or a handle (not shown in the figure) is further disposed on the upper surface of the movable stop block 3, so that the movable stop block 3 can be pulled out when the movable stop block 3 is embedded into the first slot 11.

Finally, it should be noted that the above embodiments are merely representative examples of the present invention. Obviously, the present invention is not limited to the above-described embodiments, and many modifications are possible. All changes and modifications that may be made by the technical spirit of the present invention to the above embodiments by simple modification are considered to fall within the scope of the present invention.
