Description

[Technical field]

[0001] The present invention relates to a deep hole sleeve drive rod structure, and more particularly to a deep hole sleeve drive rod structure that allows the drive head and connection head of the deep hole sleeve drive rod to be quickly attached and detached, simplifies the components, and prevents deformation due to excessive torque when a hollow tube is butted and connected to the drive head and connection head. [Background technology]

[0002] In the installation of a general cold air vent pipe or fire extinguishing pipe, a number of bolts are attached to appropriate locations on the ceiling so that they correspond to each other, and a support plate is placed horizontally between two bolts. After adjusting the height of the support plate, two nuts are screwed onto the two bolts to secure the cold air vent pipe or fire extinguishing pipe to the support plate.

[0003] However, because the bolt is installed at a high position and is long, workers must use tools such as a general torque wrench to climb up and down a ladder to screw in or remove the nut, and the nut must be turned a long distance to tighten or loosen, making the entire process very time-consuming and inconvenient. Therefore, there was a need for a deep-hole sleeve drive rod structure that improves the conventional process of screwing in a nut to a bolt, which was very time-consuming and inconvenient.

[0004] The conventional deep-hole sleeve driving rod on the market is first provided with a driving head on the head end of a straight pipe of suitable length, then a connecting head is provided on the end of the straight pipe by welding or hot melt bonding, and the straight pipe and the connecting head are processed and integrated by grinding and polishing, and the driving head is rotated by an electric tool to directly install or remove the nut.

[0005] The conventional deep-hole sleeve driving rod has the following problems (1) to (3) in practical operation. (1) The accuracy of the circularity and coaxial center between the straight pipe and the connection head was low, so there were cases where the pipe wobbled and shook during actual operation and use. (2) Since the straight pipe is integrally molded with the drive head and the connection head, it is not possible to attach and detach nuts having various dimensions and standards, and the range of application is narrow. (3) When the straight pipe or connection head breaks (at the butt joint of the power tool) or the drive head is worn out (at the butt joint of the nut), the whole pipe must be discarded, which is wasteful and not economical.

[0006] As a result of extensive research conducted by the inventors in light of the shortcomings of the above-mentioned conventional deep hole sleeve drive rods, they have completed a deep hole sleeve drive rod structure that can improve on the problems of the conventional technology. Summary of the Invention [Problem to be solved by the invention]

As shown in Figs. 1 to 4, the deep hole sleeve drive rod structure according to the first embodiment of the present invention includes a hollow tube body 10, a first drive head 20, a connection head 30, two quick-release nuts 40, and a handle cylinder body 50.

[0026] The hollow tube 10 is a tube formed in a straight line and has an appropriate length. The length of the hollow tube 10 may be determined according to actual needs. Two fitting parts 11 are provided at both ends of the hollow tube 10.

The quick-detachable nuts 40 have an outer apex abutment edge 44 on the outside thereof, which is used to abut the elastic member S. When the two quick-detachable nuts 40 are used to press and connect the hollow tube 10 against the first driving head 20 and the connecting head 30, deformation due to excessive torque is prevented.

[0030] The handle cylinder 50 is fitted into the hollow tube 10 and does not rotate together with the hollow tube 10, so that the user can easily hold it with one hand. The handle cylinder 50 has a positioning edge 51 at a position corresponding to the positioning edge 43 of the quick-release nut 40, and is used for positioning on the positioning edge 43. The handle cylinder 50 has a spring groove 52 and an inner apex abutment edge 53 at a position corresponding to the outer apex abutment edge 44 of the quick-release nut 40, one end of the elastic member S abuts on the outer apex abutment edge 44, and the other end of the elastic member S abuts on the inner apex abutment edge 53, and the elastic member S is stored and hidden in the spring groove 52, positioned to prevent accidental sliding, prevent the user's hand from being pinched and injured, and is safe and looks good.

[0031] The actual use of the present invention formed by combining the above-mentioned component structures will now be described.

[0032] Please refer to Fig. 5. Fig. 5 is an explanatory diagram of the operation of screwing the quick release nut of the deep hole sleeve driving rod structure according to the first embodiment of the present invention into the hollow tube. As shown in Fig. 5, when actually assembling the deep hole sleeve driving rod structure according to the first embodiment of the present invention, the user first screws the first female thread 41 of the quick release nut 40 into the male thread 13 of the hollow tube 10.

[0033] Please refer to Fig. 6. Fig. 6 is an explanatory diagram of the operation of fitting the connection head of the deep hole sleeve driving rod structure according to the first embodiment of the present invention. As shown in Fig. 6, the two positioning protrusions 32 of the connection head 30 are fitted and positioned into the two positioning recesses 14 of the hollow tube 10 until the connection head 30 abuts on the two positioning surfaces 15 of the hollow tube 10.

[0034] Please refer to Fig. 7. Fig. 7 is an explanatory diagram of the operation of tightening the quick-release nut of the deep-hole sleeve driving rod structure according to the first embodiment of the present invention to the connection head. As shown in Fig. 7, the second female thread 42 of the quick-release nut 40 is screwed into the male thread 33 of the connection head 30 until the quick-release nut 40 abuts on the positioning edge 34 of the connection head 30.

[0035] Please refer to Fig. 8. Fig. 8 is an explanatory diagram of the deep hole sleeve driving rod structure according to the first embodiment of the present invention being operated by using an electric tool. As shown in Fig. 8, in the work of piping a general cold air vent pipe or fire extinguishing pipe, a number of bolts 60 arranged corresponding to each other are installed at appropriate positions on the ceiling, a support plate 61 is arranged horizontally between two bolts 60, the height of the support plate 61 is adjusted, and then two nuts 62 are screwed and fixed to the two bolts 60, and the cold air vent pipe or fire extinguishing pipe 63 is installed on the support plate 61. The user aligns and inserts a hollow tube body 10 of an appropriate length to the bolt 60, and fits the first driving groove 21 of the first driving head 20 into the nut 62, and then fits the electric tool 1 into the connecting rod 31 of the connecting head 30, and the nut 62 can be directly assembled or removed, which prevents the first driving head 20 and the connecting head 30 from loosening and coming off due to the vibration of the electric tool 1. Since the hollow tube body 10 has high circularity and coaxial precision between the first driving head 20 and the connecting head 30, it is possible to prevent the deep-hole sleeve driving rod from shaking and swaying when the power tool 1 is actually used. This prevents the bolt from breaking or the straight tube from rotating due to excessive shaking caused by the straight tube being manufactured and assembled by welding or hot melt bonding as in the prior art, making it impossible to screw in the nut.
