Technical Field
[0001] This utility model belongs to the technical field of stationery products, and in particular relates to a geometric observation device. Background Technology
[0002] When studying solid geometry, it is usually necessary to observe solid geometry from different perspectives.
[0003] To facilitate multi-faceted observation of solid geometry, a type of geometry observer has emerged on the market, such as... Figure 1 The device includes a base a, a first side plate b, and a second side plate c. Each of these components is independent. The base a has a slot. To use the device, it needs to be assembled by first snapping / inserting the first side plate b and the second side plate c onto the base a, and also snapping them together. This assembly process is rather cumbersome, and the components are quite scattered.
[0004] In view of this, the inventor of this case conducted in-depth research, which led to the creation of this case. Utility Model Content
[0005] The purpose of this invention is to provide a more convenient geometric observer.
[0006] To achieve the above objectives, the technical solution of this utility model is as follows: A geometric observer includes an L-shaped folding piece and several geometric assembly blocks. The L-shaped folding piece is a one-piece molded structure with perspective, including a first connecting piece, a second connecting piece, and a third connecting piece. The first connecting piece and the second connecting piece are movably connected together in a foldable manner by plastic hinges. The first connecting piece and the third connecting piece are movably connected together in a foldable manner by another plastic hinge. The second connecting piece and the third connecting piece are snapped together. The L-shaped folded pieces are bent and joined to form a multi-faceted observation device. The multi-faceted observation device has right angles, and the first connecting piece, the second connecting piece, and the third connecting piece are perpendicularly connected to each other in pairs.
[0007] Furthermore, the second connecting piece is provided with a slot, and the third connecting piece is provided with a protrusion. The shape and size of the slot and the protrusion are respectively matched, and the protrusion is engaged in the slot.
[0008] Furthermore, the two ends of the card protrusion extend along the length direction corresponding to the card groove to form limiting teeth, and a limiting groove is formed between the limiting teeth and the periphery of the third connecting piece, and the peripheral sidewall of the card groove is limited within the limiting groove.
[0009] Furthermore, the first connecting piece, the second connecting piece, and the third connecting piece are all square pieces.
[0010] Furthermore, the first connecting piece, the second connecting piece, and the third connecting piece are all square pieces.
[0011] Furthermore, a grid is drawn on the L-shaped folded piece.
[0012] Furthermore, the grid is a square grid, and the shape and size of the grid are respectively matched with each of the geometric combination blocks.
[0013] Furthermore, the plastic hinge is a bending-resistant hinge, which is a thinner and more elastic connecting seam on the L-shaped folding piece compared to each connecting piece.
[0014] After adopting the above technical solution, the geometric observation device of this utility model has the following beneficial effects: simple structure, simple assembly operation, and convenient use. In use, the second and third connecting pieces are folded 90° relative to the first connecting piece along the corresponding plastic hinges, and then joined together. After assembling the geometric blocks, multi-angle observation is performed through the multi-faceted observation device, which is simple and clear. Compared with traditional observation devices, the observation device of this utility model has a simple structure and omits the traditionally complex base structure. It also omits the snap-fit / plug-in installation operation between the base and the side plates. This utility model features an integrated structure design, simple manufacturing process, and convenient folding operation. Compared with multi-part structures, the integrated structure is more convenient to carry, has lower production costs (molds, etc.), and can be unfolded into a flat shape when not in use, facilitating storage and production transportation.

[0016] In the picture: L-shaped folding piece 1; a connecting piece 11; a second connecting piece 12; a slot 121; a third connecting piece 13; a protrusion 131; a limiting tooth 132; a limiting groove 133; a plastic hinge 14; a grid 15; and a geometric combination block 2. Detailed Implementation
[0017] A geometric viewer, such as Figure 2 and Figure 3As shown, it includes an L-shaped folding piece 1 and several geometric combination blocks 2. The L-shaped folding piece 1 is a one-piece molded structure, including a first connecting piece 11, a second connecting piece 12 and a third connecting piece 13. The first connecting piece 11 and the second connecting piece 12 are movably connected together in a foldable manner by plastic hinges 14. The first connecting piece 11 and the third connecting piece 13 are movably connected together in a foldable manner by another plastic hinge 14. The second connecting piece 12 and the third connecting piece 13 are snapped together after being folded.
[0018] In this invention, the plastic hinge 14 is a conventional structure. Specifically, it is a plastic connection structure that allows for repeated bending. For example, it is a repeatedly bending connection structure between the lid and body of a fast food box. It only needs to be able to achieve the corresponding folding function.
[0019] In this embodiment, the L-shaped folding piece 1 is a plastic elastic connection structure. The plastic hinge 14 is a bending-resistant movable hinge. The movable hinge is a thinner and more elastic connecting seam on the L-shaped folding piece 1 compared to the first connecting piece and other connecting pieces. Each connecting piece can rotate around the corresponding movable hinge at a certain angle, specifically, it can rotate (flip) 90°.
[0020] The L-shaped folded piece 1 is bent and joined to form a multi-faceted observer. The multi-faceted observer has right angles, and the first connecting piece 11, the second connecting piece 12, and the third connecting piece 13 are connected perpendicularly to each other in pairs. The first connecting piece 11 is the bottom surface of the multi-faceted observer, and the second connecting piece 12 and the third connecting piece 13 are the sides of the multi-faceted observer.
[0021] The multi-viewing device is a transparent plastic structure.
[0022] This utility model discloses a geometric observation device with a simple structure, easy assembly, and convenient use. In use, the second connecting piece 12 and the third connecting piece 13 are folded 90° relative to the first connecting piece 11 along the corresponding plastic hinge 14, and then joined together. After assembling the geometric block, multi-angle observation is performed through the multi-faceted observation device, which is simple and clear. Compared with traditional observation devices, this utility model has a simple structure and omits the traditionally complex base, as well as the snap-fit / plug-in installation operation between the side plates and the base. This utility model features a one-piece structure design, a simple manufacturing process, and easy folding operation. Compared with multi-part structures, the one-piece structure is also more convenient to carry. When not in use, it can be unfolded into a flat shape, facilitating storage and production transportation.
[0023] As a preferred implementation method, such as Figure 2As shown, the second connecting piece 12 has a slot 121, and the third connecting piece 13 has a protrusion 131. The shape and size of the slot 121 and the protrusion 131 are matched respectively, and the protrusion 131 is engaged in the slot 121. The insertion operation is simple and efficient.
[0024] The two ends of the protrusion 131 extend along the length direction of the corresponding groove 121 to form a limiting tooth 132. A limiting groove 133 is formed between the limiting tooth 132 and the periphery of the third connecting piece 13. The peripheral sidewall of the groove 121 is limited within the limiting groove 133.
[0025] Thus, the limiting tooth 132 restricts the latching protrusion 131 from falling out of the latching groove 121. Since the L-shaped folding piece 1 has plastic elasticity, the limiting tooth 132 does not affect the engagement operation of the latching groove 121 and the latching protrusion 131, making disassembly and assembly very convenient.
[0026] In one preferred embodiment, the first connecting piece 11, the second connecting piece 12, and the third connecting piece 13 are square pieces, specifically square pieces.
[0027] A grid 15 is drawn on the L-shaped folded piece 1. In this embodiment, the grid 15 is specifically a square grid, and the shape and size of the grid 15 match those of each geometric assembly block 2. This makes it easy and quick to see the shape of the assembly from different positions.
[0028] The above embodiments and accompanying drawings are not intended to limit the product form and style of this utility model. Any appropriate changes or modifications made by those skilled in the art should be considered as not departing from the patent scope of this utility model.
