[0027] In order to make the above-mentioned objects, features and advantages of the present invention more clearly understood, the following describes in detail the specific embodiments of the present invention in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0028] Example 1:

[0029] Figure 1 This is a schematic structural diagram of the anchor bolt auxiliary leveling device provided in Example 1 of the present utility model; Figure 2 Schematic diagram of the use state of the anchor bolt auxiliary leveling device provided in Example 1 of the utility model; Figure 1-Figure 2As shown, the anchor bolt auxiliary leveling device provided in the first embodiment of the present invention includes a first abutting portion 210, a second abutting portion 310 and a horizontal component 100. The first abutting portion 210 is used to abut the top surface of the anchor bolt 420, and the second abutting portion 310 is used to abut the upper surface of the upper flange 410. The first abutting portion 210 and the second abutting portion 310 are configured to be relatively fixed. The horizontal component 100 is arranged between the first abutting portion 210 and the second abutting portion 310. The horizontal component 100 is used to maintain levelness when the top of the anchor bolt 420 protrudes from the upper surface of the upper flange 410 to a preset height.

[0030] By setting the first abutment 210 to abut the top surface of the anchor bolt 420 and the second abutment 310 to abut the upper surface of the upper flange 410, the anchor bolt auxiliary leveling device can be in a certain state when the two abut the top surface of the anchor bolt 420 and the upper surface of the upper flange 410 respectively, and a horizontal component 100 is set between the first abutment 210 and the second abutment 310. When the top of the anchor bolt 420 protrudes from the upper surface of the upper flange 410 at a preset height, the horizontal component 100 remains horizontal; and when the top of the anchor bolt 420 protrudes from the upper surface of the upper flange 410 is not at the preset height, the horizontal component 100 does not remain horizontal, and the state of the horizontal component 100 can be used as feedback, and then it can be known whether the posture of the anchor bolt auxiliary leveling device is the required posture and whether the height of the top of the anchor bolt 420 protruding from the upper surface of the upper flange 410 is the preset height, thereby facilitating the convenient adjustment of the anchor bolt 420.

[0031] Figure 3 A schematic diagram of the state of the anchor bolt auxiliary leveling device provided in the first embodiment of the present utility model when measuring the local length of the top of the anchor bolt protruding from the upper surface of the upper flange to be higher than the preset height; Figure 4 Schematic diagram of the state of the anchor bolt auxiliary leveling device provided in the first embodiment of the present invention when the local length of the top of the anchor bolt protruding from the upper surface of the upper flange is lower than the preset height; Figures 1-4 As shown, optionally, it includes a connecting component 200 and a supporting component 300, the connecting component 200 is connected to the supporting component 300 in an adjustable manner, and the first abutment portion 210 is located on the lower surface of the connecting component 200 away from one end of the supporting component 300; the second abutment portion 310 is located on the bottom surface of the supporting component 300.

[0032] By connecting the connecting component 200 and the supporting component 300 in an adjustable manner, the position of the connecting component 200 relative to the supporting component 300 can be changed, so that when the height of the top of the anchor bolt 420 protruding from the upper surface of the upper flange 410 is different, the lower surface of the connecting component 200 and the bottom surface of the supporting component 300 are adjusted to form different height differences, that is, the height difference between the first abutting portion 210 and the second abutting portion 310 is adjusted to meet different protrusion length requirements.

[0033] Specifically, in this embodiment, the support assembly 300 can be a rod-shaped or plate-shaped component, and in actual use, the support assembly 300 is generally upright. In this embodiment, the connection assembly 200 can be adjusted relative to the support assembly 300 along the approximate length of the support assembly 300. The lower surface of the connection assembly 200 is perpendicular to the support assembly 300. That is, when the local length of the top of the anchor bolt 420 protruding from the upper surface of the upper flange 410 is the same, the lower surface of the connection assembly 200 remains horizontal. More specifically, the lower surface of the connection assembly 200 is flat. If the local length of the top of the anchor bolt 420 protruding from the upper surface of the upper flange 410 is the same as a predetermined length, that is, regardless of any position of the lower surface of the connection assembly 200 contacting the top surface of the anchor bolt 420, the lower surface of the connection assembly 200 remains horizontal, and thus the horizontal assembly 100 remains horizontal. Therefore, there is no strict requirement for the specific contact position between the lower surface of the connection assembly 200 and the anchor bolt 420, thereby improving measurement convenience.

[0034] It should be noted that the orientations described in this application are based on the example of the anchor bolt-assisted leveling device being in normal use. In actual use, the bottom end of the support assembly 300 abuts the upper surface of the upper flange 410, so the second abutting portion 310 is located on the bottom surface of the support assembly 300, while the bottom surface of the connecting assembly 200 abuts the top surface of the anchor bolt 420, so the first abutting portion 210 is located on the bottom surface of the connecting assembly 200.

[0035] Of course, in other implementations, the support assembly 300 may not be vertically positioned during normal use; for example, it may be tilted, or even curved. This is feasible as long as the portion of the top of the anchor bolt 420 protruding from the upper surface of the upper flange 410, the lower surface of the connection assembly 200, the support assembly 300, and the upper surface of the upper flange 410 all exhibit the same shape when the connection assembly 200 is in contact with the top surface of the anchor bolt 420. For example, the support assembly 300 and the upper surface of the upper flange 410 may all exhibit the same shape. For example, the connection assembly 200 and the horizontal assembly 100 thereon may both remain horizontal, indicating that the length of the portion of the top of the anchor bolt 420 protruding from the upper surface of the upper flange 410 is consistent.

[0036] like Figures 1-4 As shown, optionally, the horizontal component 100 includes a balancing tube 110 , in which a leveling bubble 111 is provided, and the balancing tube 110 is fixedly connected to the connecting component 200 .

[0037] A balancing tube 110 with a leveling bubble 111 therein is used as the horizontal component 100 and is fixedly connected to the connecting component 200. When the balancing tube 110 is in a horizontal state, the leveling bubble 111 is located in the middle position in the length direction of the balancing tube 110, which makes it easy to ensure that the horizontal component 100 remains horizontal at this time.

[0038] In this embodiment, the length direction of the balancing tube 110 is the direction toward and away from the supporting assembly 300 of the connecting assembly 200. When the local length of the top of the anchor bolt 420 protruding from the upper surface of the upper flange 410 is greater than the preset height, the end of the balancing tube 110 close to the supporting assembly 300 will be lower than the other end, so the leveling bubble 111 will move toward the end of the balancing tube 110 away from the supporting assembly 300, as shown in FIG. Figure 3 If the local length of the top of the anchor bolt 420 protruding from the upper surface of the upper flange 410 is less than the preset height, the end of the balancing tube 110 close to the support assembly 300 will be higher than the other end, so the leveling bubble 111 will move toward the end of the balancing tube 110 close to the support assembly 300, as shown in FIG. Figure 4 shown.

[0039] like Figure 1-Figure 2 As shown, optionally, the connection assembly 200 is provided with an accommodating space 220 , and a threaded hole is provided on one side of the accommodating space 220 , which is threadedly connected to a tightening member 230 , and the tightening member 230 is used to press the balancing pipe 110 against the opposite side wall of the accommodating space 220 .

[0040] By providing an accommodation space 220 to accommodate the connection assembly 200 and providing a threaded hole on one side of the accommodation space 220 for threaded connection with the jacking member 230, the balancing tube 110 can be conveniently installed by placing the balancing tube 110 against the opposite sidewall of the accommodation space 220. Since the balancing tube 110 is typically a glass or plastic tube and is easily damaged during actual use, the threaded hole is provided for threaded connection with the jacking member 230. If the balancing tube 110 is damaged, the jacking member 230 can be loosened to remove the damaged balancing tube 110. After replacing the balancing tube 110, the jacking member 230 can be tightened again.

[0041] Specifically, in this embodiment, the connecting assembly 200 can be roughly in the shape of a thick plate. In normal use, the thickness of the connecting assembly 200 is horizontal. The accommodating space 220 is a hollow portion that extends through the connecting assembly 200 along the thickness direction. The length of the accommodating space 220 is the length of the balancing tube 110, that is, the direction toward and away from the support assembly 300.

[0042] For ease of operation, the jacking member 230 can be disposed on a sidewall of the accommodating space 220 away from the support assembly 300. Specifically, the axial direction of the threaded hole is aligned with the length of the accommodating space 220. Furthermore, in this embodiment, threaded holes can be provided on both sidewalls of the accommodating space 220 to threadably connect the jacking member 230. Thus, by adjusting the axial position of the two jacking members 230 relative to the threaded holes, the position of the balancing tube 110 can be changed, placing the leveling bubble 111 on the balancing tube 110 in a position that is more convenient for observation.

[0043] like Figures 1-4 As shown, optionally, a scale 320 is provided on the surface of the support assembly 300 .

[0044] The scale 320 is set on the support component 300. When the preset height is not a fixed value, the scale 320 can be used to change the height of the connecting component 200 relative to the supporting component 300, thereby ensuring that the lower surface height of the connecting component 200 is a more accurate height.

[0045] Figure 5 This is a top sectional view of the anchor bolt auxiliary leveling device provided in Example 1 of the present utility model; Figure 1 and Figure 5 As shown, optionally, the support assembly 300 includes a plate 330 ; a guide groove 331 is provided on the surface of the plate 330 , and the connecting assembly 200 has a protrusion 241 , which extends into and cooperates with the guide groove 331 .

[0046] By providing a guide groove 331 on the support assembly 300 and providing a protrusion 241 in the connecting assembly 200, so that the protrusion 241 cooperates with the guide groove 331, it can be ensured that the connecting assembly 200 reduces shaking relative to the support assembly 300 during adjustment, thereby ensuring the angle of the connecting assembly 200 relative to the support assembly 300.

[0047] Specifically, in this embodiment, the support assembly 300 can be a steel ruler, and the guide groove 331 can be a groove machined on one surface of the steel ruler by planing or milling. The length direction of the guide groove 331 can be consistent with the length direction of the steel ruler. Of course, in other implementations, the support assembly 300 can be cylindrical or cubic with a square or rectangular cross-section, and the guide groove 331 can be a groove machined on the cylindrical surface or the side of the support assembly 300.

[0048] like Figure 1 and Figure 5 As shown, optionally, the connecting assembly 200 is provided with a receiving groove 240 , the receiving groove 240 receives a portion of the plate 330 , and the protrusion 241 is provided on the side wall of the receiving groove 240 .

[0049] By providing a receiving groove 240 in the connecting component 200 to accommodate a portion of the plate 330, the protrusion 241 and the bottom of the receiving groove 240 can be used to jointly limit the horizontal relative position of the connecting component 200 and the supporting component 300 from two directions to prevent the two from shaking relative to each other.

[0050] Specifically, in this embodiment, the two side walls of the receiving groove 240 mate with the opposing surfaces of the steel ruler, thereby achieving the mating of the connecting assembly 200 and the supporting assembly 300 in the thickness direction of the steel ruler. The raised portion, for example, can be a rectangular raised portion, which mates with the guide groove 331 having a rectangular cross-section.

[0051] like Figure 1-Figure 5 As shown, optionally, the connecting assembly 200 is provided with an operating space 290, a threaded column 250 is provided in the operating space 290, the threaded column 250 is provided with an internal thread, the internal thread of the threaded column 250 is threadedly connected to a threaded tightening rod 260, and the threaded tightening rod 260 is used to tighten the support assembly 300.

[0052] By setting a threaded column 250 in the operating space 290 in the connecting assembly 200, the relative rotation of the threaded tightening rod 260 threadedly connected to the threaded column 250 and the threaded column 250 can be used to change the axial position of the threaded tightening rod 260 relative to the threaded column 250, thereby making the threaded tightening rod 260 extend from the bottom of the accommodating groove 240, thereby tightening the support assembly 300, so as to achieve the fixation of the connecting assembly 200 relative to the support assembly 300 in the length direction of the support assembly 300, so as to facilitate maintaining dimensional consistency when measuring the local length of the top of multiple anchor bolts 420 protruding from the upper surface of the upper flange 410.

[0053] Specifically, in this embodiment, the hole inside the threaded column 250 is a through hole, and the internal thread may not be set along the entire length of the hole inside the threaded column 250, but only in the area of the threaded column 250 that is far away from the support assembly 300.

[0054] like Figure 1-Figure 5 As shown, optionally, a locking nut 270 is threadedly connected to the threaded jacking rod 260 .

[0055] By setting the locking nut 270, after the threaded tightening rod 260 tightens the support assembly 300, the locking nut 270 can be used to lock the threaded tightening rod 260 on the threaded column 250, thereby preventing the threaded tightening rod 260 from loosening after multiple measurements, thereby improving the efficiency of the operation.

[0056] like Figure 1-Figure 5 As shown, optionally, the connection assembly 200 further includes a handle portion 280 , which is located on the upper surface of the connection assembly 200 .

[0057] By providing the handle portion 280 , an operator can conveniently grasp the handle portion 280 to move the entire anchor bolt auxiliary leveling device to the top of the anchor bolt 420 to be measured, and grasping the handle portion 280 will not interfere with observing the horizontal state of the level assembly 100 .

[0058] Although the present invention is disclosed as above, it is not limited thereto. Any person skilled in the art may make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be subject to the scope defined by the claims.
