Description

Deep hole socket drive rod improvement

The improvement of the deep hole sleeve driving rod of the present invention is mainly applied to the driving head and the driving tool that can quickly disassemble and assemble the deep hole sleeve driving rod; at the same time, it can ensure the deep hole sleeve driving rod, the driving head and the driving tool. Technically, the true circle between the tools and the concentric precision, there will be no swaying in the operation.

According to the general installation of air-conditioning ventilation pipes or fire pipes, a plurality of bolts arranged in pairs are installed at appropriate positions on the ceiling, and a horizontally arranged support plate is inserted between the two bolts. And after the height position of the support plate is adjusted, the two nuts are locked and fixed in the two bolts, so that the cold air ventilation pipe or the fire pipe can be erected on the support plate.

However, due to the high position of the bolt and the long length, if the construction personnel use a common socket wrench tool to lock and fix or remove the nut, they must use a ladder to climb up and down for construction. The nut must be tightened or loosened for a long distance, and the whole construction procedure is quite troublesome and inconvenient. Therefore, for the locking and fixing process of the bolt and the nut, a deep-hole sleeve driving rod is developed.

The traditional deep-hole sleeve drive rods on the market are mainly provided with a drive head at the head end of a straight pipe with an appropriate length, and a connecting head is provided at the tail end of the straight pipe by welding or heat fusion, and then by means of welding or heat welding. The straight pipe and the connector are processed and shaped by grinding and polishing As a whole, the driving head is driven and rotated by a power tool to directly assemble or disassemble the nut.

In the actual operation and use of the traditional deep-hole sleeve drive rod, there are at least the following problems and deficiencies that have yet to be overcome.

1. The accuracy of the true circle and the concentricity between the straight pipe and the connector is poor, and it is easy to sway during actual operation and use.

2. The straight tube is integrally formed with the driving head and the connecting head, and cannot be used for disassembling or assembling nuts of various sizes and specifications, and the scope of application is narrow.

3. When the straight pipe and the connecting head are broken (the connection of the power tool) and the drive head is worn (the connection of the nut), the whole pipe must be scrapped, which is quite wasteful and uneconomical.

The inventor of the present invention is currently engaged in the manufacture and design of related products, and has accumulated many years of practical experience and experience. In view of the existing problems and deficiencies of the traditional deep hole sleeve drive rod, he actively invests in the spirit of innovation and improvement. Improved sleeve drive rod.

The technical means used by the invention to solve the problem lies in that: the head and tail ends of the hollow pipe body are provided with two socket parts, and the inside of the two socket parts are provided with two socket holes and grooves, which are used as the socket drive head and the socket.

The head and the connecting head are provided with corresponding inner steps and positioning steps, and the quick-disassembly nut is used to drive the fixing cap to locate the driving head and the connecting head, except that the locking of the quick-disassembly nut can be avoided. In addition, it can prevent the driving head and the connecting head from being loosened due to the vibration of the power tool; at the same time, the hollow tube body, the driving head and the driving tool The true circle and the coaxial center have high precision, and in actual operation, there will be no swaying and shaking, so as to achieve the purpose of quickly assembling and disassembling the driving head and the connecting head.

The efficacy of the invention compared to the prior art is:

1. The true circle and coaxial center precision between the hollow tube body, the driving head and the driving tool are high, and there will be no swaying during actual operation and use.

2. The hollow tube body, the driving head and the connecting head are detachable, which can quickly disassemble and assemble the driving head and the connecting head of various sizes and specifications, suitable for disassembling or assembling various nuts, with a wide range of applications .

3. When the hollow tube body and the driving head are worn out (the joint of the nut) and the connector is broken (the joint of the power tool), as long as the driver and the connector kit are replaced, there is no need to scrap the whole piece, which is quite economical benefit.
