For the ordinary skilled person in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.

[0023] The utility model will be described in detail below with the accompanying drawings.

[0024] Reference Figures 1-5 A detachable high-precision level ruler, including horizontal ruler body 1 and two detachable horizontal ruler sub body 2 connected to the both ends of horizontal ruler body 1, the inner chamber of horizontal ruler body 1 is provided with first connecting part at both ends, one end of horizontal ruler sub body 2 is provided with second connecting part matched with first connecting part, second connecting part includes first base block 3, first base block 3 is fixedly provided with connecting block 4, the cross section of connecting block 4 is T-shaped, second connecting part includes second base block 5, second base block 5 is provided with containing cavity 6 for the rotation of connecting block 4, second base block 5 is provided with through groove 7 for the insertion of connecting block 4 at containing cavity 6, containing cavity 6 is provided with locking assembly for locking connecting block 4 after connecting block 4 rotates a certain angle.

[0025] The connecting block 4 comprises a first fixed block 8 and a second fixed block 9, the first fixed block 8 is in a cylindrical structure, the second fixed block 9 is in a cuboid structure, and the two ends of the second fixed block 9 in the length direction are provided with arc surfaces, the through groove 7 is matched with the shape of the second fixed block 9, the containing cavity 6 is in a cylindrical structure, through reasonable structure design, the connecting block 4 can realize stable rotation and locking in limited space, the arc surface design of the second base block 5 makes the rotation of the connecting block 4 more smooth, and the friction is reduced.

[0026] The locking assembly comprises a limiting groove 10 opened on the side of the containing cavity 6 away from the through groove 7, a reset spring 11 is arranged in each limiting groove 10, and a limiting bead 12 is fixedly connected to the reset spring 11, the outer wall of the limiting bead 12 is in close contact with the inner wall of the limiting groove 10, and a clamping groove 13 for clamping the limiting bead 12 is opened on the second fixed block 9.

[0027] Two limiting blocks 14 are fixedly arranged in the containing cavity 6, the two limiting blocks 14 are centrally and symmetrically distributed in the containing cavity 6, and the circumferential distance between the two limiting blocks 14 is just enough to make the second fixed block 9 rotate by 90 degrees, through the design of the limiting blocks 14, the rotation angle of the horizontal ruler body 2 relative to the horizontal ruler main body 1 is limited, so that the rotation range of the horizontal ruler body 2 is more accurate, that is, the driving delay ruler stops in time after rotating by 90 degrees, and over-rotation is avoided to make the limiting bead 12 come out of the clamping groove 13.

[0028] Limiting sheets 15 are fixedly arranged on the inner walls of the two sides of the limiting groove 10, and the distance between the two limiting sheets 15 is less than the diameter of the limiting bead 12, when the limiting sheets 15 are not arranged, the extreme position of the limiting bead 12 is controlled by the elasticity of the reset spring 11, so the reset spring 11 needs to accurately control the position of the limiting bead 12, which requires high requirements, therefore, after the limiting sheets 15 are arranged, the initial state of the reset spring 11 can also be in a compressed state, the limiting sheets 15 participate in the position control of the limiting bead 12, and the requirement for the position control of the reset spring 11 is reduced.

[0029] A decorative plug 16 is arranged at the end of the horizontal ruler body 2 away from the first connecting part, the decorative plug 16 can be fixed at the end of the horizontal ruler body 2 in a buckling, plug-in or other mode, and is mainly used for appearance and preventing sundries from entering the inside of the horizontal ruler body 2.

[0030] Working principle: the horizontal ruler of the embodiment is composed of a horizontal ruler main body 1 and two detachable horizontal ruler sub bodies 2, the connection between the horizontal ruler sub body 2 and the horizontal ruler main body 1 is realized through a first connecting part and a second connecting part, when assembling, the connecting block 4 on the horizontal ruler sub body 2 is inserted into the containing cavity 6 through the through groove 7, then a certain angle is rotated, since the connecting block 4 is in T-shaped structure, the connecting block 4 cannot be taken out after deflection in the containing cavity 6, at this time, the horizontal ruler sub body 2 and the surface of the horizontal ruler are in the same plane, at the same time, the connecting block 4 is fixed and limited through the locking assembly, so that the connecting block 4 maintains the angle when not subjected to the rotating action of external force, thereby preventing the connecting block 4 from rotating freely to the position of being aligned with the through groove 7 and taken out, and maintaining the stable connection state of the horizontal ruler main body 1 and the horizontal ruler sub body 2;

[0031] When the horizontal ruler sub body 2 needs to be detached, the locking assembly is released, and the horizontal ruler sub body 2 is rotated relative to the horizontal ruler main body 1, and then the connecting block 4 is rotated in the containing cavity 6, so that the connecting block 4 rotates back to the position of passing through the through groove 7, thereby being taken out in the through groove 7, and realizing the separation of the horizontal ruler sub body 2 and the horizontal ruler main body 1.

[0032] The specific implementation of the locking assembly is that when the second fixed block 9 enters the containing cavity 6, the surface of the second fixed block 9 first extrudes the limiting bead 12, the limiting bead 12 is entirely withdrawn in the limiting groove 10 under the action of the reset spring 11, until the second fixed block 9 is rotated to the position that the clamping groove 13 is aligned with the limiting bead 12, the limiting bead 12 loses the block of the surface of the second fixed block 9, and under the elastic recovery action of the reset spring 11, the limiting bead 12 is popped out and clamped into the clamping groove 13, realizing the locking of the connecting block 4, at this time, part of the limiting bead 12 is still located in the limiting groove 10, so that when the locking needs to be released, the horizontal ruler sub body 2 is driven to rotate relative to the horizontal ruler main body 1 again, part of the limiting bead 12 is located in the limiting groove 10 and is limited, so that it cannot be deflected with the second fixed block 9, but is gradually withdrawn from the clamping groove 13 and withdrawn in the limiting groove 10 again under the pushing action of the inner wall of the clamping groove 13. Through the cooperation of the limiting bead 12 and the clamping groove 13, it can be ensured that the connecting block 4 does not rotate freely when being locked, thereby improving the stability and reliability of the horizontal ruler in the use process, and the locking and unlocking processes can be completed only through simple rotating operation, without the need of using additional tools or steps, the operation is convenient, and the working efficiency is improved.

[0033] The detachable design can adjust the total length of the horizontal ruler according to actual needs, is convenient to carry and store, and allows users to replace only the damaged part, without the need of replacing the whole horizontal ruler, thereby reducing the use cost.

[0034] The above merely is preferred implementation manner of the present application, the protection scope of the present application is not only limited to the above examples, and belongs to the technical scheme under the idea of the present application all belongs to the protection scope of the present application. It should be pointed out that, for ordinary skilled person in the art, under the premise of not departing from the principle of the present application, some improvements and decorations, these improvements and decorations should also be considered as the protection scope of the present application.
