Description

Technical Field

[0001] The present invention relates to an improved structure of a deep hole sleeve driving rod, and is mainly used for a driving head and a connecting head of the deep hole sleeve driving rod that can be quickly disassembled and assembled; at the same time, the constituent elements can be simplified to prevent the hollow tube body from being deformed due to excessive torque when docking with the driving head and the connecting head. Background Art

[0002] Generally, the installation of air-conditioning ventilation pipes or fire-fighting pipes mainly involves installing a plurality of bolts arranged in pairs at appropriate positions on the ceiling, and inserting a support plate arranged in a horizontal direction between the two bolts. After adjusting the height of the support plate, two nuts are locked and fixed in the two bolts, so that the air-conditioning ventilation pipes or fire-fighting pipes can be mounted on the support plate.

[0003] However, since the bolt is located at a high position and is very long, if the construction worker uses a general socket wrench tool to lock or remove the nut, he must climb up and down with a ladder, and must tighten or loosen the nut over a long distance, which makes the entire construction process quite troublesome and inconvenient. Therefore, a deep hole socket drive rod has been developed for the locking and fixing process of the bolt and the nut.

[0004] The traditional deep hole sleeve driving rod available on the market mainly has a driving head at the head end of a straight tube with an appropriate length, a connecting head is provided at the tail end of the straight tube by welding or heat melting, and then the straight tube and the connecting head are processed into one piece by grinding and polishing. The driving head is driven and rotated by an electric tool to directly assemble or disassemble the nut.

[0005] The conventional deep hole sleeve driving rod has at least the following existing problems and defects in actual operation and use that need to be overcome and solved.

[0006] First, the true circle and coaxial accuracy between the straight tube and the connector are poor, and during actual operation, it is easy for the straight tube to sway or shake.

[0007] Second, the straight tube, the drive head and the connector are integrally formed, and cannot be used to disassemble or assemble nuts of various sizes and specifications, and has a narrow scope of application.

[0008] 3. When the straight tube or the connector is broken (at the joint of the electric tool) or the driving head is worn out (at the joint of the nut), the whole thing must be scrapped, which is quite wasteful and not economically efficient. Summary of the invention

[0009] The inventor is currently engaged in the manufacture and design of related products, and has accumulated many years of practical experience and insights. In view of the existing problems and defects of traditional deep hole sleeve drive rods, he actively invested in the spirit of innovation and improvement, and completed the improvement of the deep hole sleeve drive rod structure.

[0010] The technical means used by the present invention to solve the problem are: two sleeve connection parts are provided at the two ends of the hollow tube body, which are used for sleeve connection of the drive head and the connecting head; the outer parts of the two sleeve connection parts and the corresponding parts of the drive head and the connecting head are provided with positioning recesses and positioning protrusions for mutual positioning and engagement during sleeve connection; the sleeve connection parts and the outer parts of the drive head and the connecting head are provided with external threads or screw holes or combining parts for locking or combining and fixing two quick-disassembly nuts; the interior of the quick-disassembly nut is provided with a first internal thread and a second internal thread or a perforation or combining hole for locking and fixing to the external threads or screw holes or combining parts of the hollow tube body and the drive head and the connecting head; the drive head and the connecting head are locked or combined and fixed by using the quick-disassembly nut to prevent the drive head and the connecting head from loosening due to vibration of the electric tool, thereby achieving the purpose of quickly assembling and disassembling the drive head and the connecting head.

[0011] The present invention has the following advantages compared with the prior art:

[0012] 1. Simplified components, consisting of only a hollow tube, a drive head, a connector and two quick-disassembly nuts, simple to manufacture, low cost, and industrially competitive.

[0013] Second, the quick disassembly nut can be used to prevent the hollow tube from being deformed due to excessive torque when it is connected to the driving head and the connecting head.

[0014] Third, the true circle and coaxial center between the hollow tube body, the driving head and the connecting head are of high precision, and no yaw or shaking will occur during actual operation.

[0015] Fourth, the hollow tube body, the driving head and the connecting head are detachable, and the driving heads and the connecting heads of various sizes and specifications can be quickly disassembled and assembled, which is suitable for disassembling or assembling a variety of nuts and has a wide range of applications.

[0016] 5. When the hollow tube body and the driving head are worn out (nut joint) and the connecting head is broken (electric tool joint), it is only necessary to replace the driving head and the connecting head without scrapping the whole tool, which is quite economical.

[0098] The present invention, which is composed of the above-mentioned components, provides an improved structure of a deep hole sleeve drive rod, which has the following advantages in practical operation:

[0099] Please refer to Figure 5 The figure shows the quick disassembly nut 40 of the embodiment 1 of the present invention being locked into the hollow tube. During assembly, the user only needs to lock and fix the first internal thread 41 of the quick disassembly nut 40 into the first external thread 13 of the hollow tube 10 .

[0100] Please refer to Figure 6 The figure shows the sleeve action of the connector according to the first embodiment of the present invention. The two positioning protrusions 32 of the connector 30 are sleeved and positioned in the two positioning recesses 14 of the hollow tube 10 until the connector 30 abuts against the two positioning surfaces 15 of the hollow tube 10 .

[0101] Please refer to Figure 7 The figure shows the quick disassembly nut locking connector according to the first embodiment of the present invention. Next, the second internal thread 42 of the quick disassembly nut 40 is locked and fixed in the external thread 33 of the connector 30 until the quick disassembly nut 40 abuts against the positioning step 34 of the connector 30.

[0102] For general air conditioning duct or fire duct installation works, please refer to Figure 8 The figure shows a schematic plan view of the operation of the electric tool according to the first embodiment of the present invention. A plurality of bolts 60 are installed at appropriate positions on the ceiling, and a support plate 61 is inserted between the two bolts 60. After adjusting the height of the support plate 61, two nuts 62 are used to lock and fix the two bolts 60, so that the air conditioning ventilation pipe or the fire fighting pipe 63 can be installed on the support plate 61. The user only needs to align the hollow tube 10 with the bolt 60 and insert it, and use the driving groove 21 of the first driving head 20 to be sleeved in the nut 62, and then sleeve the electric tool 1 on the connecting head 30. In the connecting rod 31, the nut 62 can be directly assembled or disassembled to prevent the first drive head 20 and the connecting head 30 from loosening due to the vibration of the power tool 1; at the same time, the true circle and coaxial accuracy between the hollow tube body 10 and the first drive head 20 and the connecting head 30 are high. When the power tool 1 is actually used, the deep hole sleeve drive rod will not have the situation of swinging and shaking. Traditional straight tubes are manufactured and assembled by welding or hot melting. When the straight tube rotates, the swing is too large, which may cause the tooth rod to break, or the eccentric rotation of the straight tube may cause the nut to fail to lock.
