Detailed ways

In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model, and are not intended to limit the utility model. the

When the foldable triangular plate of the utility model is unfolded, the appearance is a conventional triangular plate structure, as shown in Figure 2 and Figure 8; in the folded type, the appearance is similar to a ruler, as shown in Figures 5, 6 and 9, 10, the volume Significantly smaller, easy to store and carry. the

Please refer to FIG. 1 , an embodiment of the foldable triangular board of the present invention includes a first side 10 , a second side 20 , and a third side 30 . The third side 30 forms a rotatable connection with the first side 10 and the second side 20 through the first fastener 40 and the second fastener 50 respectively, and the first side 10 and the second side 20 pass through the connecting piece 80 form a detachable connection. When the connecting piece 80 connects the first side 10 and the second side 20, a triangular plate is formed, as shown in FIGS. One side 10 and the second side 20 are rotated to overlap with the third side 30, as shown in Figures 5-6, forming a structure similar to a ruler, thereby reducing the volume and making it easy to carry. the

Both ends of the first side 10 respectively form a first through hole 12 and a first connection hole 14, and the two ends of the second side 20 respectively form a second through hole 22 and a second connection hole 24. Two ends of the side 30 respectively form a third through hole 32 . Wherein, the through hole on the first side 10 corresponds to a third through hole 32 at one end of the third side 30, and the second through hole 22 on the second side 20 corresponds to a third through hole 32 at the other end of the third side 30. Correspondingly, the first connection hole 14 of the first side 10 corresponds to the second connection hole 24 of the second side 20 . The first fastener 40 passes through the first through hole 12 and the corresponding third through hole 32 to rotatably connect the first side 10 to one end of the third side 30, and the second fastener 50 passes through the second through hole. The hole 22 and the corresponding third through hole 32 rotatably connect the second side 20 to the other end of the third side 30 . The connecting member 80 detachably connects the first side 10 and the second side 20 through the first connecting hole 14 and the second connecting hole 24 . the

In this embodiment, a first sealing ring 60 and a second sealing ring 70 are also included, and the first sealing ring 60 is inserted into the first through hole 12 and the corresponding third through hole 32 through interference fit. The second sealing ring 70 is inserted in the second through hole 22 and the corresponding third through hole 32 through interference fit, the first fastener 40 is inserted in the first sealing ring 60, and the second fastener 50 is inserted in the second sealing ring 70 . In this embodiment, the first fastener 40 has the same structure as the second fastener 50, both including a rod body 42, 52, a head 44, 54 formed at one end of the rod body 42, 52, and a head 44, 54 formed at the rod body 42, The undercuts 46, 56 at the other end of 52, cutouts 420, 520 are formed on the rod body 42, 52, and the outer diameters of the rod body 42, 52 are equivalent to the inner diameters of the first sealing ring 60 and the second sealing ring 70 respectively, so The outer diameters of the heads 44 , 54 and the undercuts 46 , 56 are larger than the outer diameters of the rod bodies 42 , 52 . the

When assembling, the first fastener 40 and the second fastener 50 are respectively pressed into the first seal ring 60 and the second seal ring 70. Since the rod body 42, 52 is provided with notches 420, 520, the rod body will The deformation of 42, 52 causes the undercuts 46, 56 to pass through the corresponding sealing rings 50, 70, and then the rods 42, 52 recover from deformation, and the head 44 and the undercut 46 of the first fastener 40 are buckled on the first side 10 and the first side respectively. On the outside of the third side 30, the head 54 and the undercut 56 of the second fastener 50 are pressed on the outside of the second side 20 and the third side 30 respectively, thereby preventing the first fastener 40 and the second fastener 50 from loosening. Take off, and connect the first side 10 and the second side 20 to the third side 30 rotatably. It can be understood that in other embodiments, the first side 10 and the second side 20 can also be respectively connected to the third side 30 through different fasteners. the

In this embodiment, an internal thread 82 is formed on the outer surface of the connecting piece 80, and the first connecting hole 14 and the second connecting hole 24 are both screw holes, which are respectively formed with the external thread 82 of the connecting piece 80. Matching internal threads 16, 26, when assembled, the connecting piece 80 is screw-locked in the first connecting hole 14 and the second connecting hole 24, thereby connecting the first side 10 and the second side 20 to form a triangular plate, thereby Users can easily draw various angles, vertical lines, parallel lines, etc. The present embodiment constitutes an isosceles right-angled triangular plate, the first side 10 and the second side 20 are two right-angled sides perpendicular to each other, the third side 30 is a hypotenuse, and forms an angle of 45° with the first side 10 and the second side 20 . When not in use, the connector 80 can be unscrewed from the second connecting hole 24, so that the connection between the first side 10 and the second side 20 is released, so that the first side 10 and the second side 20 can be rotated to the same position. The third side 30 overlaps to reduce the volume and facilitate storage and portability. the

7 to 10 show another embodiment of the foldable triangular plate of the present invention, which includes a first side 210 , a second side 220 , and a third side 230 . The third side 230 forms a rotatable connection with the first side 210 and the second side 220 through the first fastener 40 and the second fastener 50 respectively, and the first side 210 and the second side 220 pass through the connecting piece 80 form a detachable connection. It is different from that in this embodiment, when the first side 210 is connected to the second side 220, it is formed as a slender triangular plate, and the first side 210 and the second side 220 are two right-angled sides perpendicular to each other, and the third side 230 is The hypotenuse forms an included angle of 30° with the first side 210 and forms an included angle of 60° with the second side 220 . Similarly, the connection between the first side 210 and the second side 220 can be released by unscrewing the connecting member 80, so that the first side 210 and the second side 220 rotate to overlap with the third side 230, reducing the volume and facilitating carry. the

In the portable foldable triangular plate of the present invention, the first side 10, 210 is connected or separated from the second side 20, 220 through the connecting piece 80, so that it can be used as a conventional triangular plate for users, or overlapped together for convenient storage or storage. Portable, simple in structure, convenient in operation, simple and practical. the
