Description

Technical Field

[0001] This utility model relates to the field of measurement and positioning tools, specifically to a folding ruler capable of bidirectional measurement and positioning. Background Technology

[0002] In the fields of construction sites and civil engineering, symmetrical measurement and positioning are often required. However, when using a traditional measuring ruler to measure and position symmetrical points, it is usually necessary to measure and position in one direction first, and then measure and position again in the other direction. This method of multiple measurement and positioning is prone to cumulative errors, which not only reduces the accuracy of measurement and positioning, but also greatly reduces work efficiency, especially in situations where a large number of symmetrical operations are required. Summary of the Invention

[0003] This invention addresses the problem that existing measuring rulers require multiple measurements when measuring and positioning symmetrical points. It provides a foldable ruler capable of bidirectional measurement and positioning, which can simultaneously measure and position from the center point to both sides, and can be folded for storage.

[0004] The technical solution of this utility model is: a folding ruler capable of bidirectional measurement and positioning, comprising a ruler body with graduations, the ruler body being symmetrically divided into ruler segment one and ruler segment two, the opposite ends of ruler segment one and ruler segment two being rotatably connected, and the opposite ends being provided with fasteners, the fasteners being used to fix ruler segment one and ruler segment two when they are rotated into position, facilitating the folding and storage of the ruler body and its unfolding for use; a positioning slider is slidably provided on the ruler body, the upper end of the positioning slider is provided with a locking component one, and the lower end is connected to a plumb bob, the locking component one being used to lock the positioning slider and the ruler body.

[0005] Based on the above solution, the present invention can be further improved as follows: Furthermore, the width of one side of the ruler body is reduced, one side of the positioning slider is attached to the surface of the ruler body, and the other side is locked at the reduced width of the ruler body. When the positioning slider is on the ruler body, it can only slide along the length of the ruler body, so that it can be removed when the positioning slider slides to the end of the ruler body.

[0006] Furthermore, the cross-section of the ruler is stepped, and the cross-sectional shape of the positioning slider is adapted to the cross-sectional shape of the ruler.

[0007] Furthermore, the ruler is provided with two sets of scales. One set of scales is a unidirectional scale that increases from one end of the ruler to the other end. The other set of scales is a symmetrical scale that increases from the middle of the ruler to both ends of the ruler. It can be used for unidirectional or bidirectional measurement and positioning as needed.

[0008] Furthermore, the locking component is a threaded component with its axis perpendicular to the length direction of the ruler body. By screwing the locking component, its end can be made to abut against the ruler body, thereby making the positioning slider and the ruler body tightly pressed together.

[0009] Furthermore, the positioning slider is equipped with a pointer, the length direction of which coincides with the vertical direction of the plumb bob.

[0010] Furthermore, the plumb bob is a laser plumb bob, and the tops of both the first and second ruler sections are embedded with fixed leveling bubbles to facilitate observation of the levelness of the ruler.

[0011] Furthermore, the first and second ruler segments are rotatably connected by the first and second pivot shafts. The first pivot shaft is fixed to the first pivot shaft, and the second ruler segment is fixed to the second pivot shaft. The total length of the first and second pivot shafts is less than the minimum width of the ruler body.

[0012] Furthermore, the scale is located on the side of the ruler body with a larger width, while the fastener and the rotatable connection between ruler segment one and ruler segment two are located on the side of the ruler body with a smaller width, so as not to affect the sliding of the positioning slider.

[0013] Furthermore, a slot is provided at the narrowed width of the opposite ends of the first and second ruler segments. The fastener includes a fastening plate and a locking member two. The fastening plate is provided with a locking block that matches the slot. When the locking block is engaged in the slot, the fastening plate is in contact with the ruler body. The locking member two passes through the fastening plate and the ruler body to press against each other.

[0014] The beneficial effects of this utility model through the above technical solution are as follows: In this invention, fasteners are used to fix the ruler segments one and two when they are unfolded. Then, the plumb bob can be moved by sliding the positioning slider. During the entire measurement and positioning process, when the positioning slider slides to the dimension that needs to be measured and positioned, the positioning slider and the ruler can be fixed by screwing on the locking part one. Thus, the measurement and positioning can be completed according to the plumb bob. Attached Figure Description

[0017] The present invention will be further described below with reference to the accompanying drawings and specific embodiments: like Figure 1 As shown, a folding ruler capable of bidirectional measurement and positioning includes a ruler body 1 with graduations. The ruler body 1 is symmetrically divided into ruler segment 101 and ruler segment 102 along its length. The opposite ends of ruler segment 101 and ruler segment 102 are rotatably connected, and fasteners 2 are provided at the opposite ends. The fasteners 2 are used to fix ruler segment 101 and ruler segment 102 when they are rotated to their correct positions. Specifically, the fasteners 2 are used to fix ruler segment 101 when it is rotated to overlap with ruler segment 102 in the length direction. Sections 101 and 102 facilitate the folding, storage, and unfolding of the ruler body 1. A positioning slider 3 is slidably mounted on the ruler body 1. The upper end of the positioning slider 3 is equipped with a locking element 301, and the lower end is connected to a plumb bob 302. The locking element 301 is used to lock the positioning slider 3 and the ruler body 1. The movement of the positioning slider 3 drives the plumb bob 302 to move. When the positioning slider 3 slides to the dimension position that needs to be measured, the locking element 301 is used to lock the positioning slider 3 and the ruler body 1, so that the positioning can be performed according to the plumb bob 302.

[0018] As one possible implementation method, such as Figure 2 As shown, the width of one side of the ruler body 1 is reduced. One side of the positioning slider 3 is attached to the surface of the ruler body 1, and the other side is locked at the reduced width of the ruler body 1. This allows the positioning slider 3 to be removed only when it slides to the end of the ruler body 1. When the positioning slider 3 is on the ruler body 1, it can only slide along the length of the ruler body 1, thus ensuring the stability of the sliding of the positioning slider 3.

[0019] As one possible implementation method, Figure 2 With the orientation in the middle as a reference, the width of the left side of the ruler body 1 is reduced, so that its cross section is stepped. The cross section shape of the positioning slider 3 is adapted to the cross section shape of the ruler body 1. Specifically, the right side of the positioning slider 3 is attached to the right side of the ruler body 1, and the left side is bent downward and locked at the step of the ruler body 1, so that the cross section of the positioning slider 3 is a mirror "C" shape.

[0020] As one possible implementation method, such as Figure 1 As shown, the ruler 1 has two sets of scales. One set of scales is a unidirectional scale that increases from one end of the ruler 1 to the other end. The other set of scales is a symmetrical scale that increases from the middle of the ruler 1 to both ends of the ruler 1. The two sets of scales can be distributed on the upper and lower sides of the same surface of the ruler 1 and printed with different colors. They can be used for unidirectional or bidirectional measurement and positioning as needed.

[0021] As one possible implementation method, such as Figure 2 and Figure 3 As shown, the top of the positioning slider 3 is provided with a threaded hole 1, and the locking component 301 passes through the threaded hole 1. The locking component 301 is a threaded component whose axial direction is perpendicular to the length direction of the ruler body 1. By screwing the locking component 301, its end can be made to abut against the ruler body 1, thereby making the positioning slider 3 and the ruler body 1 tightly pressed together. The tightening of the threaded component makes it easy to use.

[0022] As one possible implementation method, such as Figure 2 and Figure 3 As shown, the positioning slider 3 is a hollow frame. In this embodiment, it consists of two mirrored "C"-shaped plates and two crossbars. The positioning slider 3 is equipped with a pointer, specifically, the pointer is located on the crossbar, and the length direction of the pointer coincides with the vertical direction of the plumb bob 302.

[0023] As one possible implementation, the plumb bob 302 is a laser plumb bob. In this embodiment, the laser plumb bob is shaped like an inverted cone, with a beam emitted from its bottom end, facilitating measurement and positioning by the user. The top center of the laser plumb bob is connected to a connecting block via a suspension line. The top of the connecting block has a threaded rod that is threadedly connected to the bottom center of the positioning slider 3, facilitating the assembly and disassembly of the plumb bob 302. Specifically, any existing laser plumb bob can be used. Figure 4 As shown, both the top of the ruler segment 101 and the ruler segment 202 are embedded with a fixed level bubble 5. Specifically, the level bubble 5 is a cylindrical level bubble, which is convenient for observing the levelness of the ruler body 1.

[0024] As one possible implementation method, such as Figure 5As shown, ruler segment 101 and ruler segment 2 102 are rotatably connected by pivot 1 401 and pivot 2 402. Pivot 1 401 and pivot 2 402 are rotatably connected. Ruler segment 101 is fixed to pivot 1 401, and ruler segment 2 102 is fixed to pivot 2 402. Specifically, there is one pivot 1 401 and two pivot 2 402. Pivot 1 401 is located between the two pivot 2 402 along the length direction, that is, the axes of pivot 1 401 and pivot 2 402 are collinear. The total length of pivot 1 401 and pivot 2 402 is less than the minimum width of ruler body 1. Space is left on ruler segment 101 and ruler segment 2 102 to facilitate pivot 2 402 and pivot 1 401, respectively.

[0025] As one possible implementation, the scale is located on the surface of the ruler body 1 with a larger width, such as... Figure 6 As shown, the fastener 2 and the rotatable connection between ruler segment 101 and ruler segment 102 are located on the side with the smaller width of the ruler body 1, so as not to affect the sliding of the positioning slider 3.

[0026] As one possible implementation method, such as Figures 5-7 As shown, both the upper and lower ends of the narrowed sections of the ruler segment 101 and ruler segment 102 are provided with slots 103. The fastener 2 includes a fastening plate 201 and a locking element 202. The fastening plate 201 is provided with a locking block 203 that matches the slot 103. When the locking block 203 is engaged in the slot 103, the fastening plate 201 fits against the ruler body 1. Specifically, the fastening plate 201 is U-shaped to avoid interference with the rotating shaft 401 and rotating shaft 402. The middle of the upper and lower ends of the fastening plate 201 is also provided with slots 103. Each part is equipped with a locking block 203, and the fastening plate 201 is provided with a groove 204. The ruler body 1 is provided with a threaded hole 2. The locking part 202 is also a threaded part, and one end is fixedly connected to a cap body that is easy to screw. The locking part 202 extends into the threaded hole 2 through the groove 204. By continuously screwing the locking part 202, the fastening plate 201 and the ruler body 1 can be pressed against each other. Under the action of the locking block 203, the ruler segment 101 and the ruler segment 102 cannot rotate at this time, thereby completing the unfolding and fixing of the ruler segment 101 and the ruler segment 102.

[0027] In this embodiment, when used: First, rotate ruler segment 101 and ruler segment 202 until they overlap in the length direction. Then, by holding the fastening plate 201, insert the locking block 203 into the slot 103. Next, insert the locking part 202 into the threaded hole 2 on the ruler body 1 through the slot 204. Tightening the locking part 202 will unfold and fix ruler segment 101 and ruler segment 202. Next, slide the positioning slider 3 from the end of ruler segment 101 or ruler segment 2 102 to ruler segment 101 or ruler segment 2 102, and then connect the plumb bob 302 to the positioning slider 3 via a threaded part, thus completing the assembly of the ruler. Since the cross section of the ruler 1 is stepped, the positioning slider 3 can only slide along the length of the ruler 1 when it is on the ruler 1. During the entire measurement and positioning process, the ruler 1 is in a horizontal state, and the plumb bob 302 is perpendicular to the ground and the ruler 1. Therefore, when the positioning slider 3 slides to the dimension that needs to be measured and positioned, the positioning slider 3 can be fixed to the ruler 1 by turning the locking part 301. Thus, the measurement and positioning are completed according to the beam emitted by the laser plumb bob.
