Description

Technical Field

[0001] This utility model relates to the field of tool technology, and in particular to an angle conversion tool suitable for low-ceilinged spaces. Background Technology

[0002] After production, excavators require bolts and screws to be tightened using fastening tools to secure all components together. The excavator's disc is primarily used to support and rotate the excavator's superstructure, enabling 360-degree rotation. The disc is typically fixed to the excavator's superstructure. When securing the disc to the superstructure with bolts, assembly personnel need to use standard fastening tools, such as socket wrenches or torque wrenches, to reach into the bolt locations and tighten them.

[0003] However, due to the narrow space between the lower and upper structures of the excavator, it is inconvenient to reach in with one's hand. During the tightening process, the assembly personnel need to repeatedly remove the fastening tool from the bolt and put the tool back in its original position before they can turn the bolt again with the tool. This process cannot effectively and quickly complete the tightening operation. Utility Model Content

[0035] See Figures 1 to 3 The present invention provides an angle conversion tool suitable for low-ceilinged spaces, including a housing 1, a rotating hole 11 on the housing 1, an opening 12 communicating with the rotating hole 11 on one side of the housing 1, a rotating seat 2 at the position corresponding to the opening 12 on the housing 1, a transverse rotating body 3 in the rotating hole 11, and a longitudinal rotating body 4 rotatably connected to the rotating seat 2; wherein, the housing 1 has a flat structure to adapt to low-ceilinged spaces, so that the housing 1 can be extended into low-ceilinged spaces.

[0036] The transverse rotating body 3 includes a rotating rod 31, one end of which passes through the housing 1. A worm gear 32 is provided at the position of the rotating rod 31 corresponding to the opening 12. A tool connecting rod 33 is provided at the end of the rotating rod 31.

[0037] The longitudinal rotating body 4 includes a turbine 41, one end of which is provided with a fastening rotating head 42. The turbine 41 meshes with the worm gear 32, and the turbine 41 and the fastening rotating head 42 are respectively rotatably connected to the rotating shaft hole 21 of the rotating seat 2.

[0038] With the above structure, when it is necessary to tighten the large disc, the housing 1 can be inserted between the upper and lower structures of the excavator, so that the tightening rotating head 42 of the longitudinal rotating body 4 faces the corresponding helical position of the large disc. Then, other suitable tools are connected to the tool connecting rod 33 of the transverse rotating body 3 to facilitate the rotation of the tool connecting rod 33. The rotational power is transmitted to the worm gear 32 through the rotating rod 31, and the worm gear 32 meshes with the worm wheel 41, causing the worm wheel 41 to rotate, thereby tightening the bolt. The other suitable tools can be an internal hex wrench or an external hex wrench, as long as they can be compatible with the tool connecting rod 33 and facilitate the rotation of the tool connecting rod 33.

[0039] In one embodiment, see Figure 1 , Figure 2 and Figure 4 The housing 1 is provided with a handle 5, which forms an angle with the transverse rotating body 3, with the angle ranging from 0 to 90 degrees. In practical applications, the handle 5 facilitates the support of the housing 1, making it easier to extend the housing 1 into low-ceilinged spaces.

[0040] In one embodiment, see Figure 3The fastening rotating head 42 is provided with a fastening groove 421 for accommodating fasteners. In practical applications, the fastening groove 421 can be matched with the corresponding fastener, so that when the fastening rotating head 42 rotates, it can drive the fastener to rotate, thereby tightening the fastener.

[0041] In one embodiment, see Figure 1 , Figure 2 and Figure 4 The housing 1 includes an upper housing 1A and a lower housing 1B. The upper housing 1A has an upper rotating groove 11A, and the lower housing 1B has a lower rotating groove 11B. The upper rotating groove 11A and the lower rotating groove 11B form a rotating hole 11. In practical applications, the housing 1 is composed of the upper housing 1A and the lower housing 1B, which facilitates the installation of the transversely rotating body 3 into the rotating hole 11 formed by the upper rotating groove 11A and the lower rotating groove 11B. The upper housing 1A and the lower housing 1B can be fixed together with screws.

[0042] The upper housing 1A has an upper opening 12A, and the lower housing 1B has a lower opening 12B. The upper opening 12A and the lower opening 12B together form an opening 12. In practical applications, the opening 12 formed by the upper opening 12A and the lower opening 12B allows the longitudinal rotating body 4 to be easily installed at the opening 12, and the opening 12 communicates with the rotating hole 11, so that the worm 32 and the turbine 41 can mesh.

[0043] The rotating base 2 includes an upper support plate 2A and a lower support plate 2B. A longitudinal rotating body 4 is rotatably connected between the upper support plate 2A and the lower support plate 2B. The upper support plate 2A is provided with an upper rotating shaft hole 21A, and the lower support plate 2B is provided with a lower rotating shaft hole 21B. The two ends of the longitudinal rotating body 4 are respectively rotatably connected to the upper rotating shaft hole 21A and the lower rotating shaft hole 21B. In practical applications, the rotating base 2 is composed of the upper support plate 2A and the lower support plate 2B, which facilitates the rotatable connection of the longitudinal rotating body 4 between the upper support plate 2A and the lower support plate 2B. The upper support plate 2A and the lower support plate 2B can be welded to the upper shell 1A and the lower shell 1B respectively.
