Description

Technical Field

[0001] This utility model relates to the field of anchor bolt technology, and more specifically to an adjustable anchor bolt. Background Technology

[0002] Anchor bolts are fasteners used to secure mechanical components, equipment, or structures to a concrete foundation, typically made of Q235 or Q345 steel (threaded steel). Currently, anchor bolts are usually installed by directly pouring concrete at the installation site. However, after the concrete hardens, the bottom of the anchor bolt is tightly bonded to the concrete, making it impossible to adjust its height, which needs improvement. Utility Model Content

[0003] In order to overcome the above-mentioned defects of the prior art, the present invention provides an adjustable anchor bolt to solve the problems existing in the background art.

[0004] This utility model provides the following technical solution: an adjustable anchor bolt, including a bolt main rod and a fixing sleeve. The fixing sleeve is movably fitted inside the upper part of the outer wall of the bolt main rod. The outer wall of the fixing sleeve is provided with external threads. Screws are threadedly connected to the lower sides of both sides of the fixing sleeve. There are two screws. Multiple threaded holes are symmetrically opened on the upper sides of both sides of the bolt main rod. The multiple threaded holes are evenly distributed on both sides of the bolt main rod. One end of each screw is threadedly connected to the inside of any one of the threaded holes. Guide blocks are welded to the lower parts of the front and rear sides of the inner wall of the fixing sleeve.

[0005] Furthermore, guide grooves are symmetrically provided on the front and rear sides of the main bolt rod, and the outer wall of the guide block is slidably connected to the inside of the guide groove.

[0006] Furthermore, a baffle is welded to the outer wall of the main bolt rod, and a square plate is welded to the bottom end of the main bolt rod.

[0007] Furthermore, a limiting plate is movably sleeved on the outer wall of the main bolt rod, and the thickness of the limiting plate is the same as the spacing between the multiple threaded holes.

[0008] Furthermore, the bottom of the limiting plate overlaps the top of the baffle, and the top of the limiting plate overlaps the bottom of the fixing sleeve.

[0009] The technical effects and advantages of this utility model are as follows:

[0010] 1. This utility model, through the cooperation of a bolt main rod, a fixing sleeve, a screw, a threaded hole, a guide block, and a guide groove, allows for the disassembly and assembly of the screw, adjustment of the height of the fixing sleeve, and vertical guidance using the guide block and guide groove. After adjustment, one end of the screw is fixedly installed inside any threaded hole, thereby fixing the fixing sleeve to the bolt main rod. Using this method, after the lower part of the bolt main rod is poured with concrete, it is convenient to adjust the height of the anchor bolt. Furthermore, the structure is simple and the operation is relatively convenient.

[0011] 2. When adjusting the fixing sleeve, this utility model can place multiple limiting plates above the baffle as needed, and the multiple limiting plates can limit the lower part of the fixing sleeve and provide support. Attached Figure Description

[0017] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The adjustable anchor bolt involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0018] Example 1:

[0019] like Figure 1-4As shown, an adjustable anchor bolt includes a bolt main rod 1 and a fixing sleeve 2. A square plate 3 is welded to the bottom end of the bolt main rod 1. The fixing sleeve 2 is movably sleeved on the upper part of the outer wall of the bolt main rod 1. The outer wall of the fixing sleeve 2 is provided with external threads. Screws 6 are threadedly connected to the lower sides of both sides of the fixing sleeve 2. There are two screws 6. Multiple threaded holes 7 are symmetrically provided on the upper sides of both sides of the bolt main rod 1. The multiple threaded holes 7 are evenly distributed on both sides of the bolt main rod 1. One end of the screw 6 is threadedly connected to the inside of any one of the threaded holes 7. The square plate 3 can increase the firmness of the bolt main rod 1 when it is poured with concrete. Through the cooperation of the screws 6 and the multiple threaded holes 7, it is easy to install the fixing sleeve 2 at different positions on the outer wall of the bolt main rod 1.

[0020] Guide blocks 8 are welded to the lower sides of the front and rear sides of the inner wall of the fixed sleeve 2. Guide grooves 9 are symmetrically opened on the front and rear sides of the bolt main rod 1. The outer wall of the guide block 8 is slidably connected to the inside of the guide groove 9. The guide block 8 can slide vertically inside the guide groove 9, thereby vertically guiding the fixed sleeve 2 and maintaining the stability of the fixed sleeve 2 when it moves on the outer wall of the bolt main rod 1.

[0021] A baffle 4 is welded to the outer wall of the bolt main rod 1. A limiting plate 5 is movably sleeved on the outer wall of the bolt main rod 1. The thickness of the limiting plate 5 is the same as the spacing between the multiple threaded holes 7. The bottom of the limiting plate 5 overlaps the top of the baffle 4, and the top of the limiting plate 5 overlaps the bottom of the fixing sleeve 2. The limiting plate 5 can be limited by the setting of the baffle 4. The distance between the threaded holes 7 is adjusted upward by the fixing sleeve 2 to fit several limiting plates 5 on the outer wall of the bolt main rod 1. The limiting plate 5 can limit the lower part of the fixing sleeve 2 and provide support.

[0022] In summary, as Figure 1-4As shown, this adjustable anchor bolt, when in use, first, the main bolt rod 1 below the baffle 4 and the square plate 3 are poured together with the concrete. After the concrete has solidified, when it is necessary to adjust the height of the anchor bolt, first unscrew the screw 6, and move the fixing sleeve 2 upwards. Remove the fixing sleeve 2 from the top of the main bolt rod 1. If the distance of the three threaded holes 7 is to be adjusted upwards by adjusting the fixing sleeve 2, three limiting plates 5 can be fitted onto the main bolt rod 1, and the lowest limiting plate 5 should be pressed down on the top of the baffle 4. The distance of the threaded holes 7 adjusted upwards by adjusting the fixing sleeve 2 is the number of limiting plates 5 fitted onto the outer wall of the main bolt rod 1. Then, the bottom of the fixing sleeve 2 is fitted onto the top of the outer wall of the main bolt rod 1. The fixed sleeve 2 simultaneously drives the guide block 8 to slide inside the guide groove 9, and the bottom of the fixed sleeve 2 overlaps with the top of the limiting plate 5. At this time, one end of the screw 6 is inserted through the fixed sleeve 2 and fixedly installed inside any threaded hole 7, so that the fixed sleeve 2 and the bolt main rod 1 can be fixed. If it is necessary to fix equipment, mechanical components or other structures, the installation port of the equipment, mechanical components or other structures can be placed on the outer wall of the fixed sleeve 2, and the lower part of the equipment, mechanical components or other structures can be limited and supported by the limiting plate 5. Then, the nut is screwed on the outer wall of the fixed sleeve 2, so that the equipment, mechanical components or other structures can be fixedly installed on the outer wall of the fixed sleeve 2.

[0023] Finally, the following points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can be mechanical or electrical connections, or internal connections between two components, or direct connections.
