Technical fields:
[0001] This utility model relates to the technical field of props, and more specifically to a low-cost antique-style stone lock used as a film and television prop. Background technology:
[0002] Film and television props are an important part of film and television production, including various set decorations and character costumes. Especially in period dramas, many antique-style props are needed. Compared to modern props, which can be purchased directly, many antique-style props can only be made. However, the antique-style props cannot be made using the old techniques. It is necessary to consider whether they are suitable for the film and television surface, and also to take cost into account. For example, stone lock props cannot be made of stone. If they were made of stone, the performers might not be able to use them. At the same time, using antique-style stone lock props is inconvenient to manufacture and costly. Therefore, there is a need for lightweight, easy-to-manufacture, and cost-effective stone lock props. Some people have suggested using foam materials for stone lock props, but the strength and appearance of foam materials need to be considered. Utility model content:

Several vertical inner support plates are fixed to the middle of the base plate, and the inner support plates are inserted into the middle of the foam body. A horizontal foam handle is inserted into a groove at the top of the foam body, and a horizontal support rod is inserted into the foam body. The two ends of the support rod are respectively inserted into the outer support plates and fixed to the outer support plates with nails.
[0005] The outer surface of the foam phantom and the outer surface of the foam handle are both covered with a hanging net, which is fixed to the wooden frame by nails; the hanging net is coated with a gypsum layer, and the outer surface of the gypsum layer is sprayed with a gravel coating.
[0006] Preferably, the outer support plates are distributed on both sides of the upper groove of the foam phantom, and the inner support plates are provided in two sets, with the inner support plates located below the upper groove of the foam phantom and close to the side wall of the upper groove of the foam phantom.
[0007] Preferably, the hanging net includes a side net in the shape of the outer contour of the foam phantom, the side net abutting against the outer surfaces of the upper, lower and left and right sides of the foam phantom and being fixed to the base plate, outer support plate and inner support plate respectively by nails;
[0008] The outer surfaces of the front and rear sides of the foam phantom are respectively abutted by a U-shaped mesh, and the outer periphery of the mesh is sewn to the side mesh with stitches; the foam handle is wrapped with a mesh tube, and the mesh tube is fixed to the support rod with nails.
[0009] Preferably, the two ends of the foam handle abut against the side netting on the outer surface of the foam phantom.
[0010] Preferably, at least one side of the left and right sides of the foam phantom has an inlet hole opposite to the support rod; and the side mesh has a through hole opposite to the support rod.
[0011] Preferably, the gravel coating is an antique gravel coating, which is composed of natural gravel, high-performance resin emulsion, inorganic pigments and binder additives.

[0018] Example: See Figures 1 to 3As shown, a low-cost antique-style stone lock used as a film and television prop includes a U-shaped foam body 1, with a wooden frame 3 inside the foam body 1. The wooden frame 3 includes a base plate 31, and the bottom of the foam body 1 has a recessed platform 11. The base plate 31 is inserted into the recessed platform 11 at the bottom of the foam body 1. Vertically upright outer support plates 32 are inserted into the left and right sides of the base plate 31, and the outer support plates 32 are respectively inserted into the sides of the foam body 1. Several vertically upright inner support plates 33 are fixed to the middle of the base plate 31, and the inner support plates 33 are inserted into the middle of the foam body 1. A horizontal foam handle 2 is inserted into the groove at the top of the foam body 1, and a horizontal support rod 34 is inserted into the foam body 1. The two ends of the support rod 34 are respectively inserted into the outer support plates 32 and fixed to the outer support plates 32 by nails 5. The bottom surface of the base plate 31 and the bottom surface of the foam body 1 can be flush.
[0019] The outer surface of the foam phantom 1 and the outer surface of the foam handle 2 are both covered with a hanging net 4, and the hanging net 4 is fixed to the wooden frame 3 by nails 5; the hanging net 4 is coated with a gypsum layer 6, and the outer surface of the gypsum layer 6 is sprayed with a gravel coating 7.
[0020] The outer support plate 32 is distributed on both sides of the upper groove of the foam phantom 1, and the inner support plate 33 is provided in two sets. The inner support plate 33 is located below the upper groove of the foam phantom 1 and is close to the side wall of the upper groove of the foam phantom 1.
[0021] The hanging net 4 includes a side net 41 in the shape of the outer contour of the foam phantom 1. The side net 41 abuts against the outer surfaces of the upper, lower and left and right sides of the foam phantom 1 and is fixed to the base plate 31, the outer support plate 32 and the inner support plate 33 respectively by nails 5. The side net 41 does not need to be ring-shaped. The starting edge of the side net 41 can be set at the base plate 31 and fixed to the base plate 31 by nails 5.
[0022] The outer surfaces of the front and rear sides of the foam phantom 1 are respectively abutted by a U-shaped mesh 42, and the outer periphery of the mesh 42 is sewn and fixed together with the side mesh 41 by stitches; the foam handle 2 is wrapped with a mesh tube 43, and the mesh tube 43 is fixed together with the support rod 34 by nails 5; the hanging net 4 composed of the above structure is easy to install and connect to the foam phantom 1.
[0023] The two ends of the foam handle 2 abut against the side mesh 41 on the outer surface of the foam phantom 1, and the foam handle 2 can constrain the side mesh 41 so that the side mesh 41 fits the outer surface of the foam phantom 1.
[0024] The foam phantom 1 has an inlet hole formed on at least one side of its left and right sides, which is opposite to the support rod 34; the side mesh 41 has a through hole formed on it, which is opposite to the support rod 34; and the bottom of the foam phantom 1 is provided with a slot opposite to the outer support plate 32 and the inner support plate 33, which facilitates the installation of the wooden frame 3 into the foam phantom 1.
[0025] The gravel coating 7 is an antique gravel coating, which is composed of natural gravel, high-performance resin emulsion, inorganic pigments and adhesive additives. Since it is an antique stone lock prop, the corresponding antique gravel coating is used. The antique gravel coating can be attached and fixed to the plaster layer by spraying.
[0026] Working principle: This structure is a low-cost antique stone lock used as a film and television prop. The main body of the antique stone lock is a foam imitation body 1, which is lightweight and easy to manufacture, thus saving costs.
[0027] Meanwhile, a wooden frame 3 is set inside the foam phantom 1. The wooden frame 3 can improve the strength of the foam phantom 1, such as avoiding the breakage of the stone lock grip part. At the same time, in order to improve the simulation of the foam phantom 1, a gravel outer layer is required. The gravel outer layer can be made of gravel coating 7, which is easy to operate. However, the gravel coating 7 has poor adhesion to the foam surface and is easy to fall off. The gravel coating 7 can adhere to plaster, so plaster can be applied to the outside of the foam phantom 1 and after curing, the gravel coating 7 can be sprayed. In order to achieve the plaster coating, a hanging net 4 needs to be installed. The hanging net 4 can be fixed to the wooden frame 3 with nails 5, which can make the plaster firmly adhere to the outer surface of the foam phantom 1.
[0028] The embodiments described above are illustrative of the present invention and are not intended to limit the present invention. Any person skilled in the art can modify the embodiments without departing from the spirit and scope of the present invention; therefore, the scope of protection of the present invention should be as set forth in the claims.
