[0028] The following describes the implementation of the present invention through specific embodiments. Those skilled in the art can readily understand the other advantages and benefits of the present invention from the contents disclosed in this specification. Obviously, the embodiments described are only a portion of the embodiments of the present invention, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort are also within the scope of protection of the present invention.

[0029] Example 1

[0030] like Figures 1 to 8 As shown, an anchor bolt in an embodiment of the first aspect of the present invention comprises a bolt 1, an outer screw rod 2 and a rubber base 4; the bolt 1 is provided with an inner thread hole 101 extending along the axial direction, one end of the outer screw rod 2 is screwed into the inner thread hole 101, and when the bolt 1 fixes and rotates the outer screw rod 2, the bolt 1 can move up and down along the axial direction of the outer screw rod 2. A screw cap 201 is fixed to the other end of the outer screw rod 2, and a grouting channel 202 extending along the axial direction of the outer screw rod 2 is provided; the rubber base 4 is a hollow chamber 401 structure with a top opening 402, and the screw cap 201 is provided with an opening 402 and is placed in the hollow chamber 401. Under the action of an external force, the outer screw rod 2 drives the screw cap 201 to rotate in the hollow chamber 401. A slurry outlet 404 is provided at the bottom of the rubber base 4, which is connected to the grouting channel 202. A plurality of slurry outlet passages 405 are evenly arranged along the radial direction on the bottom surface of the rubber base 4, and the plurality of slurry outlet passages 405 are all connected to the slurry outlet 404; wherein, the bolt 1, the external screw rod 2 and the rubber base 4 are coaxially arranged.

[0031] Optionally, the outer screw rod 2 and the screw rod cap 201 are an integrally formed structure. Since they are manufactured as a whole, there are no joints and connection points, so the structure is more stable, can withstand greater external forces and pressures, and is less likely to break or be damaged.

[0032] Optionally, the multiple slurry outlet passages 405 have the same angle between each other, so that the slurry flows out evenly from each slurry outlet passage 405, and the rubber base 4 is fixed to the floor panel or cement surface after the slurry is cured.

[0033] Optionally, the cross-section of the opening 402 is smaller than the cross-section of the screw cap 201 .

[0034] Instructions for use: Screw the anchor bolt 1 into the mounting hole 301 on the overhead plate 3 to form an overhead system. The bolt 1 can also be installed in the mounting hole 301 with interference fit. The overhead plate 3 is a rectangular plate structure, and the four mounting holes 301 are evenly arranged at the corners of the overhead plate 3. The mortar flows into the grouting channel 202 of the external screw rod 2 and then passes through the slurry outlet 404, and then flows out in a dispersed manner through multiple slurry outlet channels 405 connected by the slurry outlet 404. After the mortar solidifies, fix the bottom of the rubber base 4 on the ground panel or cement surface, and then measure the horizontal position and height of the overhead plate 3 with a ruler. Rotate the external screw rod 2 by external force to drive the screw rod cap 201 to rotate in the hollow chamber 401 of the rubber base 4. The bolt 1 is displaced up and down along the axis of the external screw rod 2 to adjust the horizontal position and height of the overhead plate 3, and level the entire overhead plate 3.

[0035] The inner thread hole 101, the grouting channel 202, the opening 402 and the slurry outlet 404 are all on the same axis, which facilitates the rapid flow of the slurry from the grouting channel 202 to the slurry outlet channel 405 of the rubber base 4, so that the rubber base 4 and the floor panel are connected by the rapid curing and solidification of the slurry.

[0036] Example 2

[0037] like Figure 1-8 As shown, an anchor bolt includes all the contents of Example 1, except that the inlet of the grouting channel 202 is a hexagonal hole 203, which extends at least partially downward along the depth direction of the outer screw rod 2. The inlet of the grouting channel 202 is a hexagonal hole 203, and the outer screw rod 2 can be rotated by simply using a hexagonal wrench to fix it in the hexagonal hole 203. The operation is simple, convenient and quick.

[0038] Example 3

[0039] like Figure 1-8 As shown, an anchor bolt includes all the contents of embodiment 2, and in addition, a plurality of anti-skid protrusions 406 are provided on the bottom surface of the rubber base 4. The anti-skid protrusions 406 further prevent the rubber base 4 from being misaligned and offset when the outer screw 2 is rotated.

[0040] The anti-slip protrusions 406 come in two forms: the first is a hemispherical or spherical dot-shaped protrusion, and the second is an arc-shaped stripe. The hemispherical or spherical dot-shaped protrusions and the arc-shaped stripes are evenly distributed on the bottom surface of the rubber base 4, so that they abut against the floor panel. At the same time, a notch 403 is provided at the opening 402 of the rubber base 4. The notch 403 is set at the edge of the opening 402, and the notch 403 is connected to the hollow chamber 401. This facilitates the installation of the screw cap 201 of the outer screw 2 into the hollow chamber 401. The notch 403 is in the shape of a strip, and the size of the notch 403 gradually increases from small to large along the direction away from the outer screw 2; further facilitating the installation of the screw cap 201 of the outer screw 2 into the hollow chamber 401. A side opening 407 is formed on the side wall of the rubber base 4 , and the notch 403 and the hollow chamber 401 are both connected to the side opening 407 , which further facilitates the installation of the screw cap 201 of the outer screw 2 into the hollow chamber 401 .

[0041] Although the present invention has been described in detail above using general descriptions and specific embodiments, it will be apparent to those skilled in the art that modifications or improvements may be made to the present invention. Therefore, such modifications or improvements, without departing from the spirit of the present invention, are within the scope of protection claimed herein.
