Description

Technical Field

[0001] This utility model relates to the field of mechanical assembly technology, and in particular to a transformable double-headed internal hexagonal sleeve assembly with a bidirectional locking structure. Background Technology

[0002] Socket extension rods, as key connecting elements between power tools and fasteners, are widely used in various fields such as machinery manufacturing, automotive repair, and building assembly. Their main function is to efficiently transmit the torque output by the power tool to fasteners such as bolts and nuts through a plug-in connection, thereby achieving efficient and stable assembly and disassembly operations.

[0003] Traditional double-ended hexagonal sockets often feature a one-way slot design, which can easily lead to loosening when switching between the two ends frequently. Sockets with locking mechanisms are mostly fixed on one side, which cannot adapt to frequent switching between the two ends, and the locking mechanism is complex and difficult to achieve bidirectional locking within a short size. Utility Model Content

[0004] The technical problem to be solved by this utility model is that the existing double-headed sleeve locking structure is unidirectional, prone to loosening, and difficult to achieve bidirectional stable switching within a compact size.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a transformable double-headed internal hexagonal sleeve assembly with a bidirectional locking structure, including a sleeve body and a connecting rod body. The sleeve body has a through-hole with a hexagonal hole inside. The top and bottom of the hexagonal hole are connected by a first internal hexagonal hole and a second internal hexagonal hole, and a stepped shaft structure with one end larger than the other is adopted. A steel ball locking structure is provided at the diagonal position inside the hexagonal hole, which is composed of abutting spring pieces and steel balls. One end of the connecting rod body has an external hexagonal segment with a magnet embedded at its end. An annular ball-locking groove is provided near the end of the external hexagonal segment. The other end is a drive connector. Through the cooperation of the steel ball and the ball-locking groove, the connecting rod body can be inserted into either end of the sleeve body and a bidirectional mechanical locking connection is achieved.

[0006] As a further improvement of this utility model, the steel ball is elastically supported by a spring sheet, partially protruding from the inner wall of the hexagonal through hole, and can be inserted into the ball-holding groove of the connecting rod body.

[0007] As a further improvement of this utility model, the magnet is fixedly disposed in the end groove of the outer hexagonal segment and is attracted to the inner wall of the sleeve body.

[0008] As a further improvement of this utility model, the sleeve body is made of S alloy steel.

[0009] As a further improvement of this utility model, the outer circular wall of the sleeve body is provided with a marking groove and a paint coating to distinguish the first internal hexagonal hole and the second internal hexagonal hole.

[0010] The beneficial effects of this utility model are as follows: By setting a hexagonal through hole inside the sleeve body and configuring a locking structure composed of spring pieces and steel balls at its diagonal positions, a two-way locking function for the connecting rod body is achieved. Compared with the traditional structure that only supports one-way snap-fit, this design allows the connecting rod body to be inserted from either the first or second internal hexagonal hole. When inserted into the ball-locking groove, the steel ball automatically snaps in under the elastic force of the spring piece, thus completing a stable mechanical locking connection. Disassembly can be achieved by simply pulling it out in the reverse direction. Simultaneously, a magnet is embedded at the end of the outer hexagonal section, forming a magnetic attraction with the inner wall of the sleeve body to assist in positioning, preventing displacement or detachment, improving safety, and meeting the needs of rapid switching between multiple specifications.

It should also be understood that the term “and / or” as used herein refers to and includes one or more of the associated listed items, any or all possible combinations thereof.

[0015] To make the technical problems to be solved, the technical solutions, and the beneficial effects of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0016] This utility model provides the following: Figure 1-4 As shown, a convertible double-headed internal hexagonal sleeve assembly with a bidirectional locking structure includes a sleeve body 1 and a connecting rod body 8. The sleeve body 1 has a through-hole 4, with a first internal hexagonal hole 2 and a second internal hexagonal hole 3 connected at its top and bottom. The sleeve body 1 employs a stepped shaft structure with one end larger than the other. The outer circular wall of the sleeve body 1 has marking grooves and a paint coating to distinguish the first internal hexagonal hole 2 and the second internal hexagonal hole 3. A steel ball locking structure is located diagonally inside the hexagonal hole 4, consisting of abutting spring pieces 6 and steel balls 7. The spring pieces 6 are located on the outside of the sleeve body 1. The steel balls 7 are elastically supported by the spring pieces 6, partially protruding from the inner wall of the hexagonal hole 4, and can be engaged in the ball-locking groove of the connecting rod body 8.

[0017] As attached Figure 1 , 2 As shown in Figures 3 and 4, one end of the connecting rod 8 has an external hexagonal segment, with a magnet 5 embedded at its end. The magnet 5 is fixedly installed in the end groove of the external hexagonal segment and attracts to the inner wall of the sleeve body 1. An annular retaining bead groove is provided near the end of the external hexagonal segment, and the other end is a drive connector 9. Through the cooperation of the steel ball 7 and the retaining bead groove, the connecting rod 8 can be inserted into either end of the sleeve body 1, achieving a bidirectional mechanical locking connection.

[0018] Working Principle: In practical implementation, the user can insert one end of the connecting rod 8 into either end of the sleeve body 1, i.e., the first internal hexagonal hole 2 or the second internal hexagonal hole 3, according to operational requirements. After insertion, the outer hexagonal segment engages with the hexagonal through hole 4 for positioning. Simultaneously, the magnet 5 embedded at the end of the outer hexagonal segment forms an attraction force with the inner wall of the sleeve body 1 through magnetic force, achieving initial centering and stable positioning. As the insertion force increases further, the retaining bead groove on the connecting rod 8 enters the central area of ​​the hexagonal through hole 4. In this area, the steel ball 7, under the elastic force of the spring piece 6, partially protrudes and automatically embeds into the retaining bead groove, achieving reliable mechanical locking. This bidirectional locking structure design allows the connecting rod 8 to be efficiently connected to the sleeve body 1 from either end without adjusting the direction. Because the sleeve body 1 adopts a stepped shaft structure with one end larger than the other, it can quickly switch between different specifications of internal hexagonal holes, and the marking groove and paint coating on the outer circular wall facilitate user identification of the insertion port. The overall structure enables bidirectional insertion and rapid, secure locking within an extremely short length, significantly improving ease of operation and assembly safety.

Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
