Description

Technical Field

[0001] The present application relates to the field of sand tables, and in particular to a stainless steel clip-on base for a sand table. Background Art

[0002] A sandbox is a widely used tool for simulation, planning, and presentation. It usually consists of a flat area filled with sand on which users can place models, markers, or other elements to create detailed scenes or plans. Sandboxes are used in many fields, including education, military, planning, and design. The sandbox base is the basic part that supports the entire sandbox structure. Its main function is to provide stable support so that the sandbox can be safely placed and used.

[0003] Since some sandboxes are large in size, their base structures are also large, and they are generally welded together by multiple profiles during processing. However, large welded bases require more space to place, which may occupy more indoor or working areas, and large bases are usually heavier and more difficult to move. This may cause trouble when rearranging or cleaning is needed, reducing the overall disassembly and transportation efficiency of the sandbox base.

[0004] In view of the above-mentioned related technologies, the inventor believes that the sand table base has the defect of being inconvenient to carry and disassemble due to its large size and weight. Therefore, a stainless steel clip-on base for a sand table is proposed to solve the above problems. Utility Model Content

Detailed implementation mode

[0020] The following will further describe this application in detail in conjunction with the attached Figures 1-5 drawings.

[0021] The embodiment of this application discloses a stainless - steel snap - type base for a sand table. Referring to Figures 1-5 , the stainless - steel snap - type base for a sand table includes two support frames 1 that are perpendicularly butted against each other. At the intersection position of the two support frames 1, a support column 2 is placed. The bottom end of the support column 2 is welded with a support base 3. Fixed card slots 4 are opened on both adjacent sides of the support column 2. A fixed convex strip 5 is fixedly installed on one side of the support frame 1. A limit groove 6 is opened at the bottom of one side of the fixed convex strip 5. A fixed inner cavity 7 is opened at the inner bottom of the support column 2. Through holes 8 are opened through the two adjacent inner walls of the fixed inner cavity 7. A movable card 9 is rotatably installed inside the fixed inner cavity 7 near the through hole 8. One side of the movable card 9 passes through the through hole 8 and extends into the limit groove 6. The limit groove 6 and the movable card 9 are engaged with each other. A first spring 10 is installed in the middle of the bottom end inner wall of the fixed inner cavity 7. The upper surface of the first spring 10 is fixedly connected with a support plate 11. A protective cover 14 is clamped on the upper surface of the support column 2 and the two support frames 1 near the intersection position. The top end inner wall of the protective cover 14 is in mutual contact with the upper surfaces of the support frame 1 and the support column 2. A support mechanism is also provided inside the support column 2 near the lower part of the fixed card slot 4 for actively supporting the fixed convex strip 5.

[0022] By moving the support frame 1 downward along the support column 2, the fixed convex strip 5 is movably clamped into the fixed card slot 4 along the inside of the fixed card slot 4, so that the fixed convex strip 5 presses the movable card 9 to rotate and drives the first spring 10 and the support plate 11 to move. When the limit groove 6 moves close to the through hole 8, the first spring 10 resets and actively pushes the support plate 11 upward to move, so that the support plate 11 pushes the movable card 9 to rotate. Furthermore, the movable card 9 rotates through the through hole 8 and is clamped into the limit groove 6, so that the movable card 9 fixes the fixed convex strip 5 inside the fixed card slot 4. Furthermore, the support frame 1 and the support column 2 are fixedly connected, and the protective cover 14 is clamped at the intersection position of the upper surfaces of the support frame 1 and the support column 2, so that the protective cover 14 clamps and fixes the top parts of the support frame 1 and the support column 2, reflecting the connection and fixing effect between the support frame 1 and the support column 2, which helps to facilitate the disassembly and assembly of the support frame 1 and the support column 2.

[0023] Referring to Figure 4 andFigure 5 The support mechanism includes a placement groove 15 which is opened at the middle part of the bottom end of the fixed clamping groove 4. At the bottom end of the inner wall of the placement groove 15, a second spring 16 is installed, and the upper surface of the second spring 16 extends outside the placement groove 15 and is movably installed with a movable support rod 17.

[0024] By enabling the movable support rod 17 to movably support the fixed convex strip 5 and enabling the movable support rod 17 to movably compress the second spring 16 along the inside of the placement groove 15, the fixed convex strip 5 is stably placed in the fixed clamping groove 4, reflecting the supporting effect of the movable support rod 17 on the fixed convex strip 5.

[0025] Refer to Figure 3 and Figure 4 On the upper surface of the support column 2, a fixed long groove 12 is opened through and extends into the fixed inner cavity 7. Inside the fixed long groove 12, a movable pressure rod 13 is movably installed. The outer diameter of the top of the movable pressure rod 13 is larger than the inner diameter of the bottom of the fixed long groove 12, and the movable pressure rod 13 and the fixed long groove 12 are mutually engaged.

[0026] By pressing the movable pressure rod 13 to move along the inside of the fixed long groove 12, the movable pressure rod 13 abuts against the outer surface of the movable clamping member 9 and pushes it to rotate, thereby enabling the movable clamping member 9 to retract into the fixed inner cavity 7, enabling the fixed convex strip 5 to move upward along the fixed clamping groove 4, and separating the support frame 1 and the support column 2 from each other, reflecting the control and adjustment effect of the movable pressure rod 13 on the movable clamping member 9.

[0027] The implementation principle of the sand table stainless steel snap - on base in the embodiment of this application is as follows: By moving the support frame 1 downward along the support column 2, the fixed rib 5 is aligned with the top opening of the fixed card slot 4. Then, the fixed rib 5 moves along the inside of the fixed card slot 4 and is snapped into the inside of the fixed card slot 4. The fixed rib 5 presses the movable latch 9 to rotate and drives the first spring 10 and the support plate 11 to move. The movable support rod 17 supports the movement of the fixed rib 5, and the movable support rod 17 moves along the inside of the placement groove 15 to compress the second spring 16. When the limit groove 6 moves close to the through - hole 8, the first spring 10 resets and moves upward to push the support plate 11, and the support plate 11 pushes the movable latch 9 to rotate. Then, the movable latch 9 rotates through the through - hole 8 and is snapped into the limit groove 6, so that the movable latch 9 fixes the fixed rib 5 inside the fixed card slot 4, and further fixes the connection between the support frame 1 and the support column 2. The protective cover 14 is snapped at the intersection position of the upper surfaces of the support frame 1 and the support column 2, so that the protective cover 14 is snap - fixed to the top of the support frame 1 and the support column 2. By pressing the movable pressure rod 13 to move along the inside of the fixed long groove 12, the movable pressure rod 13 abuts against the outer surface of the movable latch 9 and pushes it to rotate. Then, the movable latch 9 retracts into the fixed inner cavity 7, and the fixed rib 5 moves upward along the fixed card slot 4 to separate the support frame 1 and the support column 2 from each other. Compared with the prior art, this solution has the effect of facilitating the convenient disassembly and assembly between the support frame 1 and the support column 2, improving the firmness of the connection between the support frame 1 and the support column 2, solving the problem that the volume and mass of the sand table base are large and not convenient for disassembly, transportation, and improving the overall use efficiency of the support frame 1 and the support column 2.
