Description

Technical Field

[0001] This utility model relates to the technical field of power accessories, and in particular to a T-type anchor bolt for power applications. Background Technology

[0002] Existing power anchor bolts generally support heavy components and require high stability, so they are usually buried underground or fixed to the ground at the bottom. However, the diameter of the bottom of T-shaped anchor bolts is generally not large, so the stability of burying them underground or installing them is not very high. Utility Model Content

[0003] This invention aims to overcome the shortcomings of insufficient stability at the lower end of anchor bolts in existing technologies by providing a T-type anchor bolt for power applications that improves the stability of the lower part of the anchor bolt.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] A T-type anchor bolt for power applications includes a bolt, a screw head, a pressure rod, an upper fixing plate, and extension rods. The screw head is fixedly connected to the lower end face of the bolt. The upper fixing plate surrounds the bolt and is positioned above the screw head. The diameter of the upper fixing plate is larger than the diameter of the screw head. The upper fixing plate is fixedly connected to the outer side of the bolt. The lower end of the pressure rod passes through the upper end face of the bolt and is placed inside the bolt. Several extension rods are evenly distributed around the pressure rod. The cross-sectional shape of the extension rods is arc-shaped. One end of the extension rod passes through the outer side of the screw head and is fixedly connected to the lower end face of the pressure rod.

[0006] When components need to be stacked, first bury one end of the bolt head in the ground, then pass the component to be installed through the top of the bolt, then weld the upper fixing plate around the bolt, then put the other parts on the bolt and fix them with nuts, and finally knock the pressure bar to make the pressure bar spread the extension rod in all directions, increasing the diameter of the bolt head and improving the stability of the bolt. When components do not need to be stacked, first weld the upper fixing plate around the bolt, then bury the upper fixing plate and bolt head together in the ground, pass the component to be installed through the top of the bolt and fix it with nuts, and finally knock the pressure bar to make the pressure bar spread the extension rod in all directions, thus improving the stability of the lower part of the anchor bolt.

[0007] Preferably, the upper end face of the bolt has a through hole one, and the lower end of the pressure rod passes through the through hole one and is placed inside the through hole one. The side of the screw head has several through holes two, which are evenly distributed on the side of the screw head. Each through hole two corresponds to one of the extension rods, and the interior of each through hole two is connected to that of the through hole one. The correspondence between the through holes two and the extension rods facilitates accurate routing of the extension rods.

[0008] Preferably, the upper fixing plate is provided with a plurality of reinforcing ribs, which are evenly distributed around the bolts. The reinforcing ribs have a triangular cross-sectional shape, and their lower ends are fixedly connected to the upper end of the upper fixing plate. The inner surfaces of the reinforcing ribs are fixedly connected to the outer surfaces of the bolts. The reinforcing ribs can improve the strength of the upper fixing plate.

[0009] Preferably, the upper fixing plate is provided with a plurality of mounting holes, which are spaced apart from the reinforcing ribs. The mounting holes facilitate the installation of screws when screw reinforcement is required.

[0010] Preferably, the pressure rod has a raised edge and a threaded groove. The raised edge surrounds the pressure rod and is fixedly connected to the side of the pressure rod. The diameter of the raised edge is larger than the diameter of the first through hole and is positioned above the first through hole. The diameter of the raised edge is smaller than the diameter of the bolt. The threaded groove is located on the upper end face of the pressure rod. The raised edge facilitates hammering and pressing down, while the threaded groove facilitates lifting the pressure rod with tools, making disassembly convenient.

[0011] Preferably, the outer end of the extension rod is a wide, flat rectangle, and the shape of the second through hole corresponds to the shape of the extension rod. The outer end of the extension rod is positioned on the outer side of the screw head. The wide, flat rectangle allows the extension rod to have better tension on the muddy ground, improving stability.

[0012] The beneficial effects of this utility model are: improving the stability of the lower part of the anchor bolt; the two through holes correspond to the extension rod, which facilitates the accurate routing of the extension rod; the reinforcing rib can improve the strength of the upper fixing plate; the mounting hole makes it convenient to install screws when screw reinforcement is needed; the raised edge makes it easy to knock down and press down, and the threaded groove makes it easy to lift the pressure rod with tools, which is convenient for disassembly; the flat rectangle allows the extension rod to have better tension on the muddy ground, thus improving stability.

[0017] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0018] like Figure 1 and Figure 2 In one embodiment, a T-type anchor bolt for power applications includes a bolt 1, a screw head 2, a pressure rod 3, an upper fixing plate 4, and an extension rod 5. The screw head 2 is fixedly connected to the lower end face of the bolt 1. The upper fixing plate 4 surrounds the bolt 1 and is positioned above the screw head 2. The diameter of the upper fixing plate 4 is larger than the diameter of the screw head 2. The upper fixing plate 4 is fixedly connected to the outer side of the bolt 1. The lower end of the pressure rod 3 passes through the upper end face of the bolt 1 and is placed inside the bolt 1. There are several extension rods 5, which are evenly distributed around the pressure rod 3. The cross-sectional shape of the extension rod 5 is arc-shaped. One end of the extension rod 5 passes through the outer side of the screw head 2 and is fixedly connected to the lower end face of the pressure rod 3.

[0019] like Figure 2 and Figure 3 As shown, the upper end face of the bolt 1 is provided with a through hole 6. The lower end of the pressure rod 3 passes through the top of the through hole 6 and is placed inside the through hole 6. The side of the screw head 2 is provided with a through hole 7. There are several through holes 7 and they are evenly distributed on the side of the screw head 2. The through holes 7 correspond one-to-one with the extension rod 5. The through holes 7 are connected to the interior of the through hole 6.

[0020] like Figure 1 and Figure 2 As shown, the upper fixing plate 4 is provided with several reinforcing ribs 8, which are evenly distributed around the bolt 1. The cross-sectional shape of the reinforcing rib 8 is triangular. The lower end face of the reinforcing rib 8 is fixedly connected to the upper end face of the upper fixing plate 4, and the inner side face of the reinforcing rib 8 is fixedly connected to the outer side face of the bolt 1.

[0021] like Figure 1 As shown, the upper fixing plate 4 is provided with several mounting holes 9, and the mounting holes 9 and the reinforcing ribs 8 are distributed at intervals.

[0022] like Figure 1 and Figure 2 As shown, the pressure rod 3 is provided with a raised edge 10 and a threaded groove 11. The raised edge 10 surrounds the pressure rod 3 and is fixedly connected to the side of the pressure rod 3. The diameter of the raised edge 10 is larger than the diameter of the through hole 6 and is placed above the through hole 6. The diameter of the raised edge 10 is smaller than the diameter of the bolt 1. The threaded groove 11 is placed on the upper end face of the pressure rod 3.

[0023] like Figure 1 As shown, the outer end of the extension rod 5 is a wide and flat rectangle, and the shape of the through hole 7 corresponds to the shape of the extension rod 5. The outer end of the extension rod 5 is placed on the outer side of the screw head 2.

[0024] When components need to be stacked, first bury one end of the bolt head 2 of bolt 1 into the ground, then pass the component to be installed through the upper end of bolt 1, then weld the upper fixing plate 4 around bolt 1, and use fixing screws to pass through the mounting hole 9 to further improve stability. Then, put the other parts onto bolt 1 and fix them with nuts. Finally, forcefully tap the upper edge 10 of the pressure rod 3 to compress the pressure rod 3 in the first through hole 6, thereby spreading the extension rod 5 along the direction of the second through hole 7 towards the bolt head 2, increasing the diameter of the bolt head 2 and improving the stability of bolt 1. When components do not need to be stacked, first wrap the upper fixing plate 4 around bolt 1. Weld the perimeter tightly, then bury the upper fixing plate 4 and the screw head 2 together underground. After passing the component to be installed through the upper end of the bolt 1, fix it with a nut. Finally, forcefully tap the pressure rod 3 to make the extension rod 5 spread outwards. The reinforcing rib 8 on the upper fixing plate 4 can also improve the stability between the upper fixing plate 4 and the bolt 1. If disassembly or reinstallation is required, in order to better pull out the screw head 2, a tool can be connected to the threaded groove on the pressure rod 3 to lift the pressure rod 3 upwards. In this way, the extension rod 5 can return to the through hole 2 7 to the maximum extent, and the screw head 2 can also be lifted out more easily, thus achieving the purpose of improving the stability of the lower part of the anchor bolt.
