Description

Technical Field

[0001] This utility model relates to the field of manual tool technology, specifically a nested double-ring angle-compensating ratchet wrench. Background Technology

[0002] A ratchet wrench is a common hand tool that can tighten or loosen bolts or nuts in a limited space. Traditional ratchet wrenches are usually single-ring structures, with the ratchet mechanism and drive head located in the same plane. In some special working conditions, such as when the space around the bolt or nut is small, there are obstacles, or the operation needs to be performed from different angles, single-ring ratchet wrenches often cannot meet the needs of use, have poor operational flexibility, and may not be able to provide sufficient torque transmission capacity, resulting in low work efficiency or even failure to complete the operation task.

[0003] To address the problems existing in the above-mentioned technologies, a nested double-ring angle-compensating ratchet wrench is proposed. Utility Model Content

[0004] In view of the shortcomings of the prior art, this utility model provides a nested double-ring angle-compensating ratchet wrench, which overcomes the shortcomings of the prior art and solves the problems mentioned in the background art.

[0007] The inner ring ratchet mechanism, located inside the middle ring, includes the inner ring, adapter, locking gear, elastic buckle, end cap, and bolts.

[0008] The direction of the ratchet wrench can be adjusted by rotating the forward and reverse end caps. The rotating end caps, with the help of the limit rod, move the elastic buckle, thereby causing the locking gear to shift to the left or right. The shifted side engages with the first meshing tooth for positioning, thus adjusting the direction of the ratchet wrench. The middle ring and outer ring can rotate along the axis of the first bolt and the second bolt respectively, thereby achieving stepless adjustment of the compensation angle.

[0009] As a preferred embodiment of this utility model, the adapter is located inside the inner ring, one end of the adapter is fixedly connected to a sleeve rod, the other end of the adapter is provided with a threaded hole, and a pair of placement cavities adapted to the locking gear plate are symmetrically formed on the adapter.

[0010] The connecting rod can be connected to an external sleeve for use. The placement cavity can be used to lock the gear plate during assembly. When the adapter rotates, the rotation direction of the adapter is controlled according to the direction of the locking gear plate.

[0011] As a preferred embodiment of this invention, the inner wall of the inner ring is formed with a first meshing tooth in a ring array.

[0012] As a preferred embodiment of this utility model, the locking gear disc is provided with a second meshing tooth in an annular array, the second meshing tooth meshing with the first meshing tooth, and an elastic buckle is installed on one side of the locking gear disc.

[0013] The second meshing tooth engages with the first meshing tooth, and with the help of the elastic buckle, it can push the end of the locking tooth plate close to the first meshing tooth, thereby achieving bidirectional continuous tightening of the adapter.

[0014] As a preferred embodiment of this utility model, the inner ring, adapter and end cap are coaxially arranged, the end cap has a through hole adapted to the bolt, and a limiting rod that cooperates with the elastic buckle is fixedly installed on the end cap.

[0015] In a preferred embodiment of this invention, the bolt passes through the end cap and is threadedly connected to the threaded hole.

[0016] As a preferred embodiment of this utility model, a pair of first bolts that are symmetrically arranged on the middle ring and rotatably connected to the inner ring are provided.

[0017] As a preferred embodiment of this utility model, the outer end face of the outer ring is formed with snap-fit ​​grooves of different specifications.

[0018] The snap-fit ​​groove can be used with nuts of the appropriate size.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] The direction of the ratchet wrench can be adjusted by rotating the forward and reverse end caps. The rotating end caps, with the help of the limit rod, move the elastic buckle, thereby causing the locking gear to shift to the left or right. The shifted side engages with the first meshing tooth for positioning, thus adjusting the direction of the ratchet wrench. The middle ring and outer ring can rotate along the axis of the first bolt and the second bolt respectively, thereby achieving stepless adjustment of the compensation angle by 360°.

[0031] The inner ring ratchet mechanism, located inside the middle ring 7, includes an inner ring 1, an adapter 2, a locking gear 3, an elastic buckle 4, an end cap 5, and a bolt 6. The direction of the ratchet wrench can be adjusted by rotating the end cap 5 in both directions. The rotating end cap 5, with the help of the limit rod 501, moves the elastic buckle 4, thereby causing the locking gear 3 to shift to the left or right. The shifted side engages with the first meshing tooth 101 for positioning, thus adjusting the direction of the ratchet wrench. The middle ring 7 and the outer ring 8 can rotate along the axes of the first bolt 701 and the second bolt 801, respectively, thereby achieving stepless adjustment of the compensation angle by 360°.

[0032] Specifically, the adapter 2 is located inside the inner ring 1. One end of the adapter 2 is fixedly connected to a sleeve rod 201, and the other end of the adapter 2 is provided with a threaded hole 202. A pair of placement cavities 203 adapted to the locking gear 3 are symmetrically formed on the adapter 2. The sleeve rod 201 can be connected to an external sleeve for matching use. The placement cavity 203 can be used to place the locking gear 3 during assembly. When the adapter 2 rotates, the rotation direction of the adapter 2 is controlled according to the direction of the locking gear 3.

[0033] Specifically, the inner wall of the inner ring 1 has a first meshing tooth 101 in a ring array.

[0034] Specifically, the locking gear 3 is provided with a second meshing tooth 301 in a ring array. The second meshing tooth 301 meshes with the first meshing tooth 101. The elastic buckle 4 is installed on one side of the locking gear 3. The second meshing tooth 301 meshes with the first meshing tooth 101. With the help of the elastic buckle 4, the end of the locking gear 3 can be pushed close to the first meshing tooth 101, thereby realizing bidirectional continuous tightening of the adapter 2.

[0035] Specifically, the inner ring 1, the adapter 2 and the end cover 5 are coaxially arranged. The end cover 5 has a through hole that matches the bolt 6. A limiting rod 501 that cooperates with the elastic buckle 4 is fixedly installed on the end cover 5.

[0036] Specifically, bolt 6 passes through end cap 5 and is threaded into threaded hole 202.

[0037] Specifically, a pair of first bolts 701 are symmetrically arranged on the middle ring 7 and rotatably connected to the inner ring 1.

[0038] Specifically, the outer end face of the outer ring 8 is formed with snap-fit ​​grooves 9 of different specifications, which can be used with nuts of appropriate size.

[0039] Working principle: The direction of the ratchet wrench can be adjusted by rotating the forward and reverse rotating end cap 5. The rotating end cap 5, with the help of the limit rod 501, moves the elastic buckle 4, thereby causing the locking gear 3 to shift to the left or right. The shifted side engages with the first meshing tooth 101 for positioning, thereby adjusting the direction of the ratchet wrench. The middle ring 7 and the outer ring 8 can rotate along the axis of the first bolt 701 and the second bolt 801 respectively, thereby achieving stepless adjustment of the compensation angle of 360°.
