Description

Technical Field

[0001] The utility model relates to the technical field of shape-taking tools, in particular to a splicing structure and a shape-taking ruler. Background Art

[0002] A shape ruler, a multifunctional tool that combines measuring and marking functions, is popular in a variety of industries, including woodworking, interior decoration, and stone carving. It can accurately measure and mark various non-standard shapes, such as arcs, ellipses, and special forms, easily meeting diverse work challenges. While shape rulers can be customized to suit different lengths, excessive lengths can be inconvenient to carry. Consequently, many shape rulers with multiple, connectable sections are now available on the market.

[0003] For example, on October 16, 2020, publication number CN211696143U disclosed a multi-section connectable shape-taking ruler, comprising a ruler box and a mimetic sheet. The ruler box has a carrier plate inserted into the ruler frame, and the carrier plate is interspersed with a number of mimetic sheets assembled together to form an array. The ruler box includes a long ruler box and a short ruler box; multiple connecting sheets are provided between the two for connection. The tail end of the long ruler box is provided with a tail connector, and the head end of the short ruler box is provided with a head connector. Insert slots are provided in the tail connector and the head connector. The multiple connecting sheets are inserted into the head connector at both ends. The insert slots in the tail connector allow the long ruler box and the short ruler box to be symmetrically spliced into one. The long ruler box and the short ruler box are used separately. Depending on the measurement requirements, the two can be used together to measure the longest object, or separately to measure small and medium-sized objects, as well as the front and back sides or corners of an object. The combination of these two methods is diverse. However, the patented connection needs to be fixed with screws, and other tools are needed for disassembly and assembly, which is inconvenient to use in practice.

[0004] Therefore be necessary to provide a kind of shaping ruler that is easy to splice. Summary of the Invention

[0005] The purpose of the present invention is to overcome the deficiencies of the prior art and to provide a splicing structure and a shape-taking ruler, which are intended to solve the technical problem of inconvenient splicing in the prior art.

[0006] To achieve the above-mentioned purpose, the utility model proposes a splicing structure, including a base plate; connecting protrusions and connecting grooves are respectively provided on both sides of the base plate, and the connecting protrusions are L-shaped; locking sliders and locking grooves are respectively provided on both sides of the base plate, and the locking sliders can move on the base plate.

[0007] Preferably, the locking slider is provided with anti-slip teeth, and the base plate is provided with a movable track, and the anti-slip teeth can move back and forth in the movable track.

[0008] Preferably, a clamping plate is provided on the substrate, and the connecting protrusion can be clamped on the clamping plate; four connecting protrusions are provided, evenly distributed on one side of the substrate.

[0009] Preferably, the locking slider and the connecting protrusion are arranged on the same side.

[0010] To achieve the above-mentioned purpose, the present invention proposes a shape-taking ruler, which uses the above-mentioned splicing structure, has scale lines arranged on the substrate, and has a shape-taking sheet arranged inside the substrate.

[0011] Preferably, a protective cover is provided on one side of the base plate where the connecting protrusion is provided; and a cam lock is provided on one side of the base plate.

[0012] Preferably, the cam lock comprises a cylindrical plate fixed on the base plate, a cam rotatably arranged on the cylindrical plate, and a fixed plate; one end of the fixed plate is connected to the cam, and the other end is connected to the shaping sheet.

[0013] Compared with the prior art, the present invention provides a splicing structure and a shape-taking ruler with the following beneficial effects: each shape-taking ruler is provided with a connecting protrusion and a connecting groove on both sides. The connecting protrusion of one shape-taking ruler connects to the connecting groove of the other shape-taking ruler and is laterally moved and clamped on the clamping plate. Then, the locking slider is moved to just fit into the locking groove, making the connecting protrusion and the connecting groove unable to move, thus achieving a locking effect. When disassembling, one only needs to move the locking slider to disengage it from the locking groove, and then move the connecting protrusion to disengage it from the connecting groove, making disassembly convenient.

Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0028] The present invention provides a shape ruler. In order to measure longer objects, multiple shape rulers need to be spliced together for use. Figure 1 and Figure 2 This ruler is made by joining two shape-taking rulers. It can be used alone or joined together. A single shape-taking ruler includes a base plate 1 with scale lines. Within the base plate 1 are a number of shape-taking slices 17, shown in the figure as a long strip. The shape-taking slices 17 are aligned with irregular objects to shape them.

[0029] To facilitate splicing, see Figure 2-5 The present invention proposes a splicing structure, comprising a base plate 1; a connecting protrusion 11 and a connecting groove 12 are respectively provided on both sides of the base plate 1, and the connecting protrusion 11 is L-shaped; a locking slider 13 and a locking groove 14 are respectively provided on both sides of the base plate 1, and the locking slider 13 can move on the base plate 1. Figure 1 After the two pieces of the ruler are joined together, a connecting protrusion 11 is provided at one end. In order to prevent the connecting protrusion 11 from breaking during transportation or use, a protective cover 2 is provided at one end of the connecting protrusion 11. Figure 2 When splicing is required, the protective cover 2 is removed and another shaping ruler is connected to the connecting protrusion 11 on this side to form a splice.

[0030] See Figure 2-3 In an optional embodiment, the locking slider 13 is provided with anti-slip teeth 131, and the base plate 1 is provided with a movable track 15. The anti-slip teeth 131 can move back and forth within the movable track 15. Manually moving the anti-slip teeth 131 causes the locking slider 13 to move back and forth. When the locking slider 13 engages the locking groove 14 of the other shape ruler, the locking slider 13 is engaged. After the locking slider 13 is retracted, the locking slider 13 and the locking groove 14 are locked, and the two shape rulers can be separated.

[0031] See Figure 6-7In an optional embodiment, a card plate 16 is provided on the base plate 1, and the connecting protrusion 11 can be stuck on the card plate 16; there are four connecting protrusions 11, evenly distributed on one side of the base plate 1. Four connecting grooves 12 are provided on the card plate 16, and the opening size of the connecting grooves 12 is substantially the same as the size of the outer side of the connecting protrusion 11. After the connecting protrusion 11 is inserted into the connecting groove 12, it is translated. The connecting protrusion 11 is an L-shaped plate, and a U-shaped opening is formed between the connecting protrusion 11 and the base plate 1. The U-shaped opening is stuck on the card plate 16 by translation. At this time, the locking slider 13 corresponds to the locking groove 14, and the locking slider 13 can be moved to achieve locking.

[0032] See Figure 2-3 In an optional embodiment, the locking slider 13 and the connecting protrusion 11 are arranged on the same side. A cam lock 3 is provided on one side of the base plate 1. Preferably, the cam lock 3 is provided on the side away from the locking slider 13. This makes it more convenient to use and does not cause mutual interference.

[0033] Furthermore, after the shape is formed, the shaping sheet 17 needs to be fixed. Figure 6-7 The cam lock 3 includes a cylindrical plate 31 fixed to the base plate 1, a cam 32 rotatably mounted on the cylindrical plate 31, and a fixed plate 33. One end of the fixed plate 33 is connected to the cam 32, and the other end is connected to the shaping sheet 17. One end of the fixed plate 32 is disposed outside the shaping sheet 17, and the other end is located inside the cam 32. When the shaping sheet 17 is fixed, the rotation of the cam 32 will move the fixed plate 32 to the left, and the fixed plate 32 presses the shaping sheet 17 to the left to fix it.

[0034] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements or improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
