Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of expansion bolt fastening, and specifically relates to an expansion bolt ceiling installation rod. Background Art
[0002] In building decoration projects, expansion bolts, as a common fastener, are widely used in the fixing work of floors, walls, ceilings and other positions. Especially when installing or repairing the ceiling, in order to ensure the safety and stability of lamps, ventilation equipment and other decorative materials, it is often necessary to use expansion bolts to firmly fix them in the appropriate positions. However, the traditional expansion bolt installation method has certain limitations and inconveniences in the operation process.
[0003] For expansion bolts that need to be fixed on the floor or wall, the installation process can usually be easily completed by using common tools such as ordinary wrenches. However, when it is necessary to install expansion bolts on the ceiling, construction workers often need to use ladders or other auxiliary facilities to reach the required working height, which not only increases the construction difficulty, but also may bring safety hazards. In addition, when working at heights, the operation efficiency of construction workers will be greatly reduced, and it is easy to cause physical fatigue by maintaining an unnatural posture for a long time, which further affects the accuracy and safety of the work.
[0004] In view of the above problems, the existing solutions include using a long-handled wrench or other extended manual tools to try to complete the installation from the ground, but these tools have limited effects in actual applications and cannot completely solve the problem of inconvenient operation. Therefore, there is an urgent need in the market for a new tool that can effectively simplify the installation process of ceiling expansion bolts, reduce the risk of working at heights, and improve work efficiency. Summary of the Utility Model
[0005] In view of the deficiencies in the background art, the utility model provides an expansion bolt ceiling installation rod.
[0006] The technical solution adopted by the utility model is: an expansion bolt ceiling installation rod, including a connection head, an extension rod and a percussion rotary joint;
[0007] One end of the connection head is connected to the extension rod, and the other end is provided with a connection part for adaptively connecting to the output end of an electric tool;
[0008] One end of the percussion rotary joint is connected to the extension rod, and the other end is provided with a connection hole for connecting to the rotary action end of the expansion bolt to transmit the rotary torque, and a percussion hole for connecting to the expansion bolt is provided at the bottom of the connection hole.
[0009] Further, the connection hole is a hexagonal hole adapted to the rotary action end of the expansion bolt.
[0010] Furthermore, the connecting head is provided with a connecting stud 1, and the extension rod is provided with an internal screw hole 1 connected to the connecting stud 1.
[0011] Furthermore, the electric tool is an electric hammer, a hand drill or an impact drill.
[0012] Furthermore, the extension rod is a fixed rod of a fixed length or an adjustable rod of an adjustable length.
[0013] Furthermore, it also includes a connecting component for connecting the extension rod and the knocking rotary joint, the connecting component is a second connecting stud, and an internal screw hole three threadedly connected to the second connecting stud is provided on the end of the knocking rotary joint away from the knocking hole.
[0014] Furthermore, the connecting component is a connecting sleeve, and an internal screw hole 2 is arranged in the connecting sleeve. The striking rotary joint and the extension rod are provided with a connecting stud 3 for threaded connection with the internal screw hole 2.
[0015] Furthermore, the second connecting stud is integrally formed with the extension rod.
[0016] Furthermore, the connecting head, the extension rod and the striking rotary joint are arranged on the same center line, and the center lines of the connecting hole and the striking hole are arranged colinearly with the center lines of the connecting head, the extension rod and the striking rotary joint.
[0017] Furthermore, there are multiple extension rods, and the connecting studs three on the extension rods can be threadedly connected with the inner screw holes one, so that the multiple extension rods can be screwed together with the inner screw holes one of adjacent extension rods through the connecting studs three.
[0018] The beneficial effects of the utility model are:
[0019] 1. Easy to operate: Through the combination of the connector, extension rod and percussion swivel joint, construction workers only need to connect the connector to common power tools (such as electric hammers) to achieve the percussion of expansion bolts into holes and rotation fixation, which greatly shortens the construction time and improves work efficiency. There is no need to climb ladders and other climbing equipment, which greatly reduces the difficulty of operation and reduces the inconvenience caused by climbing operations.
[0020] 2. Improve construction efficiency: The installation rod has the functions of knocking and rotating. During installation, first use the knocking function of the electric tool to quickly knock the expansion bolt into the expansion bolt hole drilled in the ceiling, and then switch to the rotation function to complete the tightening, which greatly shortens the installation time, significantly improves the construction efficiency compared to the traditional method, and saves labor costs.
[0021] 3. Improve construction safety: Construction workers do not need to work at heights, avoiding potential safety hazards such as falls that may occur when operating on ladders. This provides a more reliable safety guarantee for the construction process, reduces the likelihood of safety accidents, and is conducive to ensuring the personal safety of construction workers and the smooth progress of the project.
