[0022] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0023] Embodiment 1

[0024] As Figure 1 shown:

[0025] A multifunctional calibration device for construction includes a first calibration ruler 1, a second calibration ruler 2 arranged on the first calibration ruler 1, and a third calibration ruler 3 fixed at one end of the first calibration ruler 1. The second calibration ruler 2 is hinged to one end of the third calibration ruler 3 through a hinge shaft. A marking assembly 4 is installed inside the third calibration ruler 3, and a conical hammer body 5 is installed on the marking assembly 4. The conical hammer body 5 is located outside the third calibration ruler 3. A horizontal glass bubble 6 is fixedly installed on the upper surface of the second calibration ruler 2 through a rectangular groove.

[0026] In this implementation scheme: The existing device {publication (announcement) number}: CN212320740U discloses a multifunctional calibration device for construction. The marking assembly 4 in this application document adopts the same technical means as in this prior art. This technical means will not be elaborated here one by one. Regarding this existing main body, this application makes further improvements. For details, refer to the disclosed technology below; To solve the technical problems existing in this prior art, as disclosed in the background art above, "When the above design is used, although the calibration device is horizontally calibrated before measurement to ensure the calibration accuracy of the calibration ruler, it does not have shielding protection for the horizontal glass bubble 6 on the horizontal calibration ruler. In the construction environment, it is easy for concrete to adhere to its surface, affecting the observation effect, or touching and damaging it. When the plumb bob is in a hanging state, it is easy to be affected by the external wind environment and cause shaking, causing the plumb bob to drive the ink line to tilt, thereby affecting the marking effect and thus affecting the use effect of the device." In combination with the use, this problem is obviously a real and relatively difficult problem to solve. In view of this, to solve this technical problem, an auxiliary component 7 is added in this application document. All the power equipment involved in this product is powered by an external power supply.

[0027] It should be noted that: The accessories used in the marking assembly 4 have been disclosed in the publication number CN212320740U, and its use effect can be referred to the publication number CN212320740U (that is, the "winding handle, ink storage tank, plumb bob, wire roller and ink line components" disclosed in this prior art);

[0028] It should be noted that: The first calibration ruler 1 includes a laser distance measurement probe and a laser distance measurement display screen installed. For the specific structure and operation, reference can be made to the publication number CN212320740U.

[0029] Furthermore:

[0030] As Figures 1-5 shown:

[0031] On the second calibration ruler 2 and the third calibration ruler 3, an auxiliary component 7 is installed. The auxiliary component 7 includes shielding protection plates 701 that are symmetrically arranged and slidably connected inside the second calibration ruler 2, and telescopic rods 703 that are symmetrically arranged and fixed between the shielding protection plates 701 and the second calibration ruler 2, and a first spring 702 wound around the outer surface of the telescopic rods 703. Both ends of the first spring 702 are fixedly connected to the shielding protection plates 701 and the second calibration ruler 2 respectively. One end of the third calibration ruler 3 is fixedly installed with a laser ray instrument 709 through an opened installation groove. A calibration groove 710 is opened on one side of the surface of the conical hammer body 5 close to the laser ray instrument 709;

[0032] A moving groove is opened on one side of the inside of the second calibration ruler 2 close to the shielding protection plate 701. The shielding protection plate 701 and the second calibration ruler 2 are slidably connected through this moving groove. The calibration groove 710 corresponds to the ray end of the laser ray instrument 709.

[0033] In this implementation: For this multifunctional calibration device for construction, when in use, when using the horizontal spirit level 6 on the second calibration ruler 2 to test the level of the wall surface, by sliding the two shielding protection plates 701 and moving them in the direction away from each other, at the same time, compressing the first spring 702 and the telescopic rods 703. The telescopic rods 703 can increase the stability of the movement of the shielding protection plates 701 until a certain opening is generated between the two shielding protection plates 701, so that the horizontal spirit level 6 is exposed for observation. When the observation of the horizontal spirit level 6 is completed, at this time, the first spring 702 rebounds and drives the two shielding protection plates 701 to approach and close each other to block and shield the horizontal spirit level 6. Thus, in the construction environment, when not in use, it can prevent concrete from adhering to the surface of the horizontal spirit level 6 and affecting the observation situation, and at the same time avoid the situation of collision damage, further improving the use effect of the device. When the marking component 4 is in use, by releasing the conical hammer body 5 through the ink line (not shown in the figure) of the marking component 4. When the conical hammer body 5 moves down a certain distance, by turning on the laser ray instrument 709, when the emitted ray corresponds to the calibration groove 710 on the conical hammer body 5, at this time, the conical hammer body 5 is fixed. In this process, it can be judged that the ink line and the marking component 4 are in a horizontal state. Through this operation, in the external environment, it can prevent the conical hammer body 5 from shaking due to wind force and causing the ink line to tilt, thereby improving the marking accuracy of the device.

[0034] It should be noted that the process of emitting laser by the laser ray instrument 709 is to stimulate the electrons in the working material through the excitation source, so that it generates photons under the action of stimulated radiation, and then these photons are reflected back and forth and amplified in the resonant cavity, and finally form enough energy to be emitted to form rays.

[0035] Going further;

[0036] In an optional embodiment, one side of the shielding protection plate 701 is rotatably connected to the limit rod 704 through a bearing, and an extrusion block 705 is provided on one side of the calibration ruler 2 near the two groups of limit rods 704, and a straight rod 708 is fixed to the lower surface of the extrusion block 705, and a spring 2 706 is wound around the outer surface of the straight rod 708, and the two ends of the spring 2 706 are respectively fixedly connected to the calibration ruler 2 and the extrusion block 705, and the extrusion block 705 is located between the two groups of limit rods 704;

[0037] A T-shaped sliding groove 707 is provided on the surface of the calibration ruler 2 near the extrusion block 705, and the sliding groove 707 is connected to the rectangular groove. The extrusion block 705 and the calibration ruler 2 are slidably connected through the sliding groove 707. A through groove is provided on the inside of the calibration ruler 2 near the straight rod 708, and the straight rod 708 and the calibration ruler 2 are slidably connected through this through groove.

[0038] In this embodiment: in this process, by pressing the extrusion block 705, the straight rod 708 is driven to move downward, and the spring 2 706 is compressed. As the extrusion block 705 moves downward, the limit rod 704 is squeezed. Since the limit rod 704 rotates on the shielding protection plate 701, the limit rod 704 can rotate on the surface of the extrusion block 705 during the extrusion of the limit rod 704, thereby reducing friction and improving the movement effect of the extrusion block 705 on the limit rod 704. As the extrusion block 705 moves downward, the two groups of limit rods 704 are squeezed away from each other, and the shielding protection plate 701 is driven to move by the limit rod 704, and the two groups of shielding protection plates 701 are unfolded. Through this operation, the problem of fingers blocking the horizontal glass bulb 6 when sliding the shielding protection plate 701 open is solved, which affects the observation line of sight. At the same time, it is convenient to open the shielding protection plate 701, further improving the use effect of the device.

[0039] Going further;

[0040] In an optional embodiment, a resisting rod 711 is provided inside the conical hammer body 5, a locking bolt 712 is threadedly connected to the surface of the conical hammer body 5 through a threaded hole, the bottom end of the locking bolt 712 is in contact with the resisting rod 711, and a socket 713 adapted to the resisting rod 711 is provided on one side of the surface of the conical hammer body 5 close to the locking bolt 712;

[0041] A placement groove is provided on one side of the inside of the conical hammer body 5 near the contact rod 711. The contact rod 711 is located in the placement groove provided in the conical hammer body 5, and the insertion hole 713 is perpendicular to the placement groove.

[0042] In this embodiment: By rotating the locking bolt 712, the locking of the contact rod 711 is released. Subsequently, the contact rod 711 is withdrawn and inserted into the insertion hole 713 so that the contact rod 711 abuts against the wall surface. Then, the locking bolt 712 is rotated to squeeze and fix the contact rod 711. Through the abutting force of the contact rod 711 held by hand against the wall surface, at this time, the conical hammer body 5 is firmly fixed on the surface of the contact rod 711. Subsequently, when the ink line is ejected, the conical hammer body 5 is prevented from tilting and affecting the accuracy of the marking, further improving the use effect of the device.

[0043] The working principle and use process of the utility model are as follows: when the multifunctional calibration device for buildings is used, when the horizontal glass bubble 6 on the calibration ruler 2 is used to test the horizontality of the wall surface, the two groups of shielding and protective plates 701 are slid to move away from each other, and at the same time, the spring 1 702 and the telescopic rod 703 are compressed, and the telescopic rod 703 can increase the stability of the movement of the shielding and protective plates 701, until the two groups of shielding and protective plates 701 have a certain opening, so that the horizontal glass bubble 6 is exposed for observation. When the observation of the horizontal glass bubble 6 is completed, the spring 1 702 rebounds and drives the two groups of shielding and protective plates 701 to close together to block and shield the horizontal glass bubble 6, so that in the building environment, When not in use, concrete is prevented from adhering to the surface of the horizontal glass bubble 6 and affecting the observation situation, and collision damage is avoided, thereby further improving the use effect of the device. In this process, by pressing the extrusion block 705, the straight rod 708 is driven to move downward, and the spring 706 is compressed. As the extrusion block 705 moves downward, the limit rod 704 is squeezed. Since the limit rod 704 rotates on the shielding protection plate 701, the limit rod 704 can rotate on the surface of the extrusion block 705 during the extrusion process of the limit rod 704, thereby reducing friction and improving the movement effect of the extrusion block 705 on the limit rod 704. As the extrusion block 705 moves downward, the two groups of limit rods 704 are squeezed away from each other, and the limit rod 706 is squeezed away from each other. 04 drives the shielding protection plate 701 to move and unfolds the two sets of shielding protection plates 701. Through this operation, it is solved that when the shielding protection plate 701 is slid open by fingers, it is easy for the fingers to block the horizontal glass bulb 6, affecting the observation line of sight. At the same time, it is convenient to open the shielding protection plate 701, and the use effect of the device is further improved. When the marking component 4 is in use, the conical hammer body 5 is released through the ink line of the marking component 4 (not shown in the figure). When the conical hammer body 5 moves down to a certain distance, the laser ray meter 709 is turned on. When the emitted ray corresponds to the calibration groove 710 on the conical hammer body 5, the conical hammer body 5 is fixed at this time. In this process, it can be judged that the ink line and the marking component 4 are in Horizontal state, through this operation, when used in an external environment, the cone hammer body 5 is prevented from shaking due to wind force and causing the ink line to tilt, thereby improving the accuracy of the device marking. When the ink line is ejected, the locking bolt 712 is rotated to release the lock of the interference rod 711, and then the interference rod 711 is pulled out and inserted into the socket 713, so that the interference rod 711 is in conflict with the wall, and then the locking bolt 712 is rotated to squeeze and fix the interference rod 711, and the resistance force of the interference rod 711 against the wall is exerted by holding the interference rod 711. At this time, the cone hammer body 5 is firmly fixed on the surface of the interference rod 711, and then when the ink line is ejected, the cone hammer body 5 is prevented from tilting and affecting the accuracy of the marking, thereby further improving the use effect of the device.
