[0020] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0021] like Figure 1-5As shown, a reinforced concrete casting mold includes a base 8, an inner cylinder 1, and an outer cylinder 2. The base 8 is circular, and the radial sections of the inner cylinder 1 and the outer cylinder 2 are both annular. The outer cylinder 2 and the inner cylinder 1 are both mounted on the base 8, and the outer cylinder 2 is sleeved on the inner cylinder 1. The outer cylinder 2 and the inner cylinder 1 are coaxially arranged, and the axis of the inner cylinder 1 is perpendicular to the diameter of the base 8. The axis of the inner cylinder 1 passes through the center of the base 8.

[0022] The inner wall of the inner cylinder 1 is provided with a reinforcement unit, which includes 6 reinforcement members 3. The reinforcement members 3 are arc-shaped and located on the same circumference. The 6 reinforcement members 3 are spaced apart. The center of the circumference where the reinforcement members 3 are located is located on the axis of the inner cylinder 1. The outer side of the reinforcement members 3 is connected to the inner ring of the inner cylinder 1. The cross-section of the reinforcement members 3 in the plane where the axis of the inner cylinder 1 is located is L-shaped. A fixing ring 4 is provided between the 6 reinforcement members 3. The axis of the fixing ring 4 coincides with the axis of the inner cylinder 1. The outer ring of the fixing ring 4 abuts against the reinforcement members 3.

[0023] Both the inner cylinder 1 and the outer cylinder 2 have slots at their ends away from the base 8. The number of slots in the inner cylinder 1 and the outer cylinder 2 are equal and correspond one-to-one. A fixing rod 5 is provided between the inner cylinder 1 and the outer cylinder 2. The number of fixing rods 5 is equal to the number of slots in the inner cylinder 1. One end of the fixing rod 5 is located in the slot of the inner cylinder 1, and the other end of the fixing rod 5 is located in the slot of the outer cylinder 2. The fixing rod 5 coincides with one of the diameters of the outer cylinder 2.

[0024] The outer wall of the outer cylinder 2 is provided with several reinforcing rings 7 from top to bottom.

[0025] Preferably, the reinforcing member 3 is located on the inner side of the inner cylinder 1 at one end near the base 8.

[0026] Preferably, the cross-section of the reinforcing ring 7 along the axial direction of the inner cylinder 1 is trapezoidal, and the plane containing the lower base of the trapezoidal cross-section of the reinforcing ring 7 is in contact with the outer wall of the outer cylinder.

[0027] Preferably, both ends of the fixing rod 5 are provided with fixing balls 6, the fixing balls 6 and the fixing rod 5 are integrally formed, the diameter of the fixing balls 6 is larger than the width of the fixing rod 5, and the fixing balls 6 are located in the slot.

[0028] Preferably, the inner cylinder 1 is fixedly connected to the reinforcing member 3.

[0029] At intervals, reinforcement members 3 with supporting functions are provided at the bottom of the inner wall of the inner cylinder 1. This can support the bottom of the inner cylinder 1 and reduce the probability of deformation. The intervals of the reinforcement members 3 can adapt to a certain degree of deformation and reduce rigid stress. In fact, the overall shape of the reinforcement member 3 is stepped. Fixing rings 4 are provided at its step parts to achieve overall continuous support and improve the support strength of the inner side.

[0030] A fixing rod 5 is set at the end of the inner cylinder 1 and the outer cylinder 2 away from the base 8. The fixing ball 6 is respectively locked in the slot of the inner cylinder 1 and the inner cylinder 2, which plays a good limiting role, so that the distance between the inner cylinder 1 and the outer cylinder 2 remains unchanged and the dimensional accuracy is improved. A trapezoidal cross-section reinforcing ring 7 is set on the outer periphery of the outer cylinder 2, which also plays the role of reinforcing rib. The trapezoidal shape is mainly to increase the contact area between the reinforcing ring 7 and the outer cylinder 2, and ensure the connection strength of the reinforcing ring 7 to the outer cylinder 2.

[0031] Compared with existing technologies, this reinforced concrete casting mold uses six reinforcing members 3 on the inner side of the inner cylinder 1 for clamping and fixed rings 4 for limiting. Fixed rods 5 are set at the upper ends of the inner cylinder 1 and the outer cylinder 2 to maintain the distance between them. Furthermore, a trapezoidal cross-section reinforcing ring 7 is set on the cylinder wall, which improves the overall structural strength and stability, extends the service life, and ensures structural accuracy.

[0032] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
