[0023] In order to more clearly understand the above-mentioned purposes, features and advantages of the utility model, the utility model is described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that, in the absence of conflict, the embodiments of the present application and the features in the embodiments can be combined with each other. In the following description, many specific details are set forth in order to fully understand the utility model, and the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0025] This embodiment provides a convenient concrete demoulding device, such as Figure 1-Figure 3 The device shown mainly comprises a first petal body 1, a second petal body 2 and a knob 3. The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0026] First, the first petal body 1 includes a first bottom plate 10 and a first side wall 11, and the second petal body 2 includes a second bottom plate 20 and a second side wall 21. The first petal body 1 and the second petal body 2 are interlocked with each other, so that the first bottom plate 10 and the second bottom plate 20 are closely fitted, and at the same time, the first side wall 11 and the second side wall 21 are also connected to each other on both sides, together forming a complete cavity 4 for containing the load-bearing concrete. This cavity 4 can be designed as a cuboid or a cylinder to adapt to concrete products of different shapes and sizes.

[0027] In order to ensure that the first petal body 1 and the second petal body 2 can be tightly buckled together, a first clamping strip 12 is provided on one side of the first side wall 11, and a first clamping groove 13 is provided on the other side thereof. Similarly, a second clamping strip 22 is provided on one side of the second side wall 21, and a second clamping groove 23 is provided on the other side thereof. When the first petal body 1 and the second petal body 2 are buckled together, the first clamping strip 12 will be clamped into the second clamping groove 23, and the second clamping strip 22 will be clamped into the first clamping groove 13, thereby achieving a tight connection between the two.

[0028] In some optional embodiments, the toothed edges of the first bottom plate 10 and the second bottom plate 20 are engaged with each other. The side of the first bottom plate 10 facing the second bottom plate 20 is designed as the first toothed edge 14, and the side of the second bottom plate 20 facing the first bottom plate 10 is designed as the second toothed edge 24. When the first petal body 1 and the second petal body 2 are buckled, the first toothed edge 14 and the second toothed edge 24 will be engaged with each other, and by setting the matching edges of the first bottom plate 10 and the second bottom plate 20 as curves, the contact area is increased, and the stability and sealing of the device are further enhanced.

[0029] In some optional embodiments, the knob 3 can be set on the first base plate 10 or on the second base plate 20. When the knob 3 is set on the first base plate 10, it will be pressed against the second base plate 20; conversely, when the knob 3 is set on the second base plate 20, it will be pressed against the first base plate 10. When demoulding is required, by rotating the knob 3, the knob 3 will apply pressure to the other side, so that the buckling relationship between it and the other base plate becomes loose. Due to the tightening effect of the knob 3, when the knob 3 is rotated and released, the buckling relationship between the first petal body 1 and the second petal body 2 becomes easy to open. At this time, the user can separate the first petal body 1 and the second petal body 2 manually or with the help of tools, thereby releasing the solidified concrete.

[0030] In some optional embodiments, a bottom hole 5 is provided on the outward side of the first bottom plate 10 or the second bottom plate 20. The knob 3 is installed in the bottom hole 5. A rotating hole 6 is provided at the center of the bottom hole 5, and the rotating hole 6 cooperates with the rotating handle 30 of the knob 3. When the knob 3 is rotated, the bottom of the knob 3 cooperates with the rotating hole 6, so that the knob 3 can rotate in the bottom hole 5.

[0031] In some optional embodiments, the knob 3 includes a turning handle 30 and a lever 31, and the turning handle 30 and the lever 31 are relatively fixedly connected. The turning handle 30 is arranged at the opening of the bottom hole 5 for easy operation. The lever 31 is arranged at the bottom of the bottom hole 5 to generate a pressing force with the first bottom plate 10 or the second bottom plate 20. In addition, a rotating groove 7 is arranged on the periphery of the bottom hole 5, and the turning handle 30 is placed in the rotating groove 7. Such a design not only makes the operation of the knob 3 more stable, but also ensures that the surface of the knob 3 will not exceed the bottom surface of the first bottom plate 10 or the second bottom plate 20, thereby not affecting the flatness and use effect of the device.

[0032] In summary, the portable concrete demoulding device provided in this embodiment has the advantages of simple structure, convenient operation, good sealing, etc., and can greatly improve the production efficiency and quality of concrete products.

[0033] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Therefore, any modification, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the technical solution of the present invention are still within the scope of the technical solution of the present invention.
