DETAILED DESCRIPTION
[0021] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.
[0022] Depend on Figure 1-5 The present invention discloses a multifunctional ruler, comprising a ruler main body 1 and a ruler sub-body 2, wherein the ruler main body 1 and the ruler sub-body 2 are connected via a rotating shaft 4, the ruler sub-body 2 can rotate around the rotating shaft 4, and both the ruler sub-body 2 and the ruler main body 1 have a first scale 3, and when the ruler main body 1 and the ruler sub-body 2 are on the same straight line, the first scale 3 is used to measure the length of the straight line.
[0023] When the ruler sub-body 2 rotates, there is an angle between the side surface of the ruler sub-body 2 and the side surface of the ruler main body 1, so that the angle can be easily measured (or the angles of different angles can be drawn).
[0024] A rotating member capable of rotating is provided on the ruler body 1, and a fixing rod 13 and a toggle rod 14 are respectively provided on both sides of the rotating member. When the rotating member rotates, the fixing rod 13 and the toggle rod 14 can slide in different directions. The fixing rod 13 is located in the ruler body 1, and one end of the fixing rod 13 can be inserted into the ruler auxiliary rod 2. When sliding, the toggle rod 14 can cooperate with the rotating shaft 4 to rotate the rotating shaft 4. A third scale 15 is provided outside the rotating member, and the third scale is used to mark the rotation angle of the ruler auxiliary body 2.
[0025] The use of the rotating member can limit whether the ruler sub-body 2 is fixed and the rotation angle of the ruler sub-body 2, so that the user can use the ruler sub-body 2 to measure the angle or draw a predetermined angle. The use of the third scale 15 can mark the angle between the ruler sub-body 2 and the ruler main body 1, so that the user can grasp the size of the angle.
[0026] A slide groove 6 is provided on the ruler body 1, and a sliding block 8 capable of sliding is provided in the slide groove 6. The sliding block 8 has a through hole 9 and a first rotating block 10. A second scale 7 is provided on one side of the slide groove 6. The second scale 7 is used to mark the distance between the through hole 9 and the rotating member.
[0027] The slider 8, together with the second scale 7, can help the user grasp the distance between the through hole 9 and the rotating part. When in use, the user inserts the pen into the through hole 9 and then presses the rotating part. At this time, the ruler body 1 can rotate around the rotating part to draw a circle, thus achieving the function of a compass.
[0028] When the device is in use, it can not only act as a ruler to measure length or draw a straight line, but also measure angles or draw angles of predetermined angles, and can also draw circles, acting as a compass. This makes the device have multiple functions and is convenient for users to use.
[0029] The rotating shaft 4 is fixedly connected with a first gear 5 , and a first rack is arranged on the side of the toggle rod 14 . The first rack meshes with the first gear 5 , so that when the toggle rod 14 slides, the rotating shaft 4 can rotate accordingly.
[0030] When the rotating member is rotated, the rotating member can toggle the toggle lever 14, so that the toggle lever 14 toggle the first gear 5, thereby causing the ruler body 2 to rotate by a predetermined angle.
[0031] The rotating member includes a sleeve block 11, a second rotating block 12 and a second gear 16. The second rotating block 12 is inserted into a slot 21 in the sleeve block 11. A bottom fixing block 22 is fixed to the lower end of the second rotating block 12. The bottom fixing block 22 is connected to the slot 21 through a spring 20. The second gear 16 is located outside the sleeve block 11. The second rotating block 12 extends outside the ruler body 1. When the second rotating block 12 is at a predetermined position and rotates, the second gear 16 can rotate.
[0032] When the rotating part is implemented, when it is necessary to measure the angle or draw the predetermined angle, the user rotates the second rotating block 12, and the second rotating block 12 can drive the sleeve block 11 to rotate, and then the sleeve block 11 drives the second gear 16 to rotate, thereby rotating the shaft 4.
[0033] Of course, in the initial stage of the rotation of the second rotating block 12 , the rotating shaft 4 does not rotate. At this time, the fixing rod 13 slides out of the ruler body 2 . Only when the fixing rod 13 completely slides out of the ruler body 2 can the rotating shaft 4 be moved by the moving rod 14 .
[0034] The use of the spring 20 allows the second rotating block 12 to be pressed. When the user needs to use the compass, the user presses the second rotating block 12 so that the end of the sleeve block 11 can be pressed against the paper surface (or working surface), and then rotates the pen tip so that the ruler body 1 can rotate around the sleeve block 11 to draw a circle.
[0035] The second gear 16 cooperates with the fixed rod and the toggle rod 14 in a gear-rack meshing manner.
[0036] As a first embodiment of the cooperation between the sleeve block 11, the second rotating block 12 and the second gear 16, there is the following technical solution:
[0037] A connecting rod 17 is provided through the sleeve block 11, a first tooth groove 18 is provided on the side of the second rotating block 12, and a second tooth groove 19 is provided on the inner wall of the second gear 16. One end of the connecting rod 17 extends into the first tooth groove 18, and the other end of the connecting rod 17 extends into the second tooth groove 18. A third gear is provided on one end of the connecting rod 17, and a second rack is provided in the first tooth groove 18. The second gear cooperates with the third gear so that when the second rotating block 12 moves downward, the connecting rod 17 can rotate, and the connecting rod 17 is threadedly engaged with the sleeve block 11.
[0038] In this embodiment, pressing the second rotating block 12 downward can rotate the connecting rod 17, and the connecting rod 17 is threadedly matched with the sleeve block 11, so that the connecting rod 17 can also move to one side, thereby separating the end of the connecting rod 17 from the second tooth groove 18. At this time, the rotation of the sleeve block 11 will not drive the ruler sub-body 2 to rotate, thereby avoiding the inconvenience caused to the user by the rotation of the ruler main body 1 and the influence of the rotation limit of the ruler sub-body 2 on the operation of drawing a circle.
[0039] As a second embodiment of the cooperation between the sleeve block 11, the second rotating block 12 and the second gear 16, there is the following technical solution:
[0040] The second gear 16 is fixed to the outside of the sleeve block 11, a second annular tooth 24 is fixed to the upper end of the bottom fixed block 22, and a first annular tooth 23 is fixed to the inner wall of the slot 21. The first annular tooth 23 can cooperate with the second annular tooth 24, so that when the second rotating block 12 rotates, the sleeve block 11 can rotate accordingly.
[0041] In this embodiment, the second rotating block 12 is pressed downward, and the first annular teeth 23 are separated from the second annular teeth 24, so that the ruler body 2 does not rotate when drawing a circle.
[0042] The lower end surface of the sleeve block 11 has an arc-shaped surface to facilitate the rotation of the sleeve block 11.
[0043] A strip-shaped tooth 27 is also provided on the inner wall of the slide groove 6, and a first tooth 25 and a second tooth 26 are provided in the slider 8. The first tooth 25 and the second tooth 26 are respectively provided on both sides of the first rotating block 10. A fourth gear is fixedly connected to the outside of the first rotating block 10, and a third rack is provided on the side surfaces of the first tooth 25 and the second tooth 26. The fourth gear cooperates with the third rack so that when the first rotating block 10 rotates, the first tooth 25 and the second tooth 26 can approach / move away from each other.
[0044] The use of the first latching teeth 25 , the second latching teeth 26 and the strip-shaped latching teeth 27 can fix the position of the slider 8 , so that when drawing a circle, a circular surface of a predetermined size can be drawn.
