Description

Technical Field

[0001] The utility model relates to the technical field of mechanical tools, in particular to an anti-rotation wrench for an engine water pump pulley. Background Art

[0002] When installing the water pump pulley during the engine assembly stage, it is usually necessary to use a crowbar or a screwdriver handle to pass through the deweighting hole of the water pump pulley, clamp the reinforcement rib of the water pump housing, fix the water pump pulley and use a torque wrench to tighten the torque;

[0003] The traditional fixing method has limitations on the structure of the water pump pulley, requiring a hole that can pass through a crowbar or screwdriver. In addition, improper operation of this method will damage the water pump pulley and the water pump housing, and in severe cases, the water pump pulley will be scrapped;

[0004] A Chinese patent with publication number "CN202220897905.3" discloses "an engine water pump pulley anti-rotation tooling, which includes a pulley cover, a reinforcement plate and a block." Although it can "solve the problem of difficult installation of the engine water pump pulley," since the engine water pump bolts have different specifications, it is necessary to produce tooling of corresponding specifications for bolts of different sizes. Producing them one by one is likely to cause tooling waste and increase manufacturing costs. In addition, the tooling installation steps are relatively complicated, and more parts are required. In addition, the various parts cooperate with each other. The loss of vulnerable and consumable parts will affect the installation accuracy.

[0005] To solve the above problem, this case proposes an anti-rotation wrench for an engine water pump pulley. Utility Model Content

[0006] The main purpose of the utility model is to provide an anti-rotation wrench for an engine water pump pulley, which can effectively solve the technical problems in the background technology.

[0007] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0008] The invention discloses an anti-rotation wrench for an engine water pump pulley, comprising an angle disc, a wrench body 1 and a wrench body 2. A threaded rod is arranged at the center of the angle disc, the threaded rod and the angle disc are movably connected, a gear 1 is arranged at the lower position outside the threaded rod, the gear 1 and the threaded rod are fixedly connected, a nut is arranged above the angle disc, and the nut and the threaded rod are threadedly connected, one side of the outside of the gear 1 is fixedly connected to the wrench body 2, the wrench body 1 is fixedly connected to the outside of the angle disc, and a hand-held wrench handle is arranged on one side of the outside of the wrench body 2.

[0009] As a further solution of the utility model, a movable groove is provided on the outside of the angle disc, and the gear 1 is located in the movable groove.

[0010] As a further solution of the utility model, a square groove is provided through one side of the outer portion of the wrench body, and a second gear is provided in the square groove.

[0011] As a further solution of the utility model, the size of gear one is larger than that of gear two, and gear one is in meshing state with gear two.

[0012] As a further solution of the utility model, a turning handle is arranged through the top of the wrench body 1 and the upper and lower parts of the gear 2. The turning handle is movably connected to the wrench body 1, and is fixedly connected to the gear 2.

[0013] As a further solution of the utility model, a slide groove is provided through the upper and lower parts of the wrench body 1 and the wrench body 2, and an adapter is provided above the slide groove.

[0014] As a further solution of the utility model, a sliding block is provided at the bottom of the adapter, and the sliding block is rectangular and is located in the sliding groove.

[0015] As a further solution of the utility model, a threaded groove is opened through the bottom of the sliding block, a fixing bolt is arranged in the threaded groove, and a gasket is sleeved on the outside of the fixing bolt.

[0016] The beneficial effects of the utility model are as follows:

[0017] By setting the adapter, the slider and the slide groove, the movable design can be adapted to the bolts of different specifications of the water pump pulleys of different engines, so that the bolts of different specifications can also use the same set of engine water pump pulley wrenches, saving costs;

[0018] By setting the angle disc, the angle between the wrench body one and the wrench body two can be adjusted to ensure that the engine crankshaft pulley cannot be fixed linearly due to special circumstances. When in use, first loosen the nut and adjust the angle between the wrench body one and the wrench body two. At the same time, you can also rotate the gear two to drive the gear one to rotate, so as to adjust the angle, so that the angle can be fine-tuned, which is more practical.

[0024] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0025] like Figure 1-3 As shown, an anti-rotation wrench for an engine water pump pulley comprises an angle disc 1, a wrench body 1 2, and a wrench body 2 3. A threaded rod 4 is arranged through the center of the angle disc 1, and the threaded rod 4 is movably connected to the angle disc 1. A gear 1 6 is arranged at a lower position outside the threaded rod 4, and the gear 1 6 is fixedly connected to the threaded rod 4. A nut 5 is arranged above the angle disc 1, and the nut 5 is threadedly connected to the threaded rod 4. One side of the outside of the gear 1 6 is fixedly connected to the wrench body 2 3, the wrench body 1 2 is fixedly connected to the outside of the angle disc 1, and a hand-held wrench handle 12 is arranged on one side of the outside of the wrench body 2 3.

[0026] When the angle adjustment of the spanner body 2 3 is completed, it can be locked by tightening the nut 5 .

[0027] In this embodiment, a movable groove is formed on the outside of the angle disc 1, and the gear 1 6 is located in the movable groove.

[0028] Gear 1 6 is located in the movable groove and can rotate in the movable groove.

[0029] In this embodiment, a square groove is formed on one side of the outer portion of the wrench body 1 2 , and a gear 2 7 is disposed in the square groove.

[0030] Gear 2 7 is located in the square groove and can rotate in the square groove.

[0031] In this embodiment, the size of gear 1 6 is larger than that of gear 2 7 , and gear 1 6 and gear 2 7 are in meshing state.

[0032] In this embodiment, a turning handle 8 is provided through the top of the wrench body 2 and the upper and lower parts of the gear 2 7. The turning handle 8 is movably connected to the wrench body 2, and the turning handle 8 is fixedly connected to the gear 2 7.

[0033] By turning the handle 8, the gear 2 7 rotates and drives the gear 1 6 to rotate, so that the angle can be fine-tuned.

[0034] In this embodiment, a slide groove 9 is provided through the upper and lower parts of the wrench body 1 2 and the wrench body 2 3 , and an adapter 10 is provided above the slide groove 9 .

[0035] By providing the adapter 10 and the slider 11, it can be adapted to different threaded sleeves. When in use, the fixing bolt 14 is directly loosened and removed, and then threaded sleeves of different types are inserted into the slider 11 and tightened, thereby being adapted to different types of bolts of the engine water pump pulley.

[0036] In this embodiment, a slider 11 is disposed at the bottom of the adapter 10 . The slider 11 is rectangular and is located in the slide groove 9 .

[0037] The sliding block 11 is rectangular so that the adapter 10 will not rotate freely in the sliding groove 9 .

[0038] In this embodiment, a thread groove 15 is formed through the bottom of the sliding block 11 , a fixing bolt 14 is disposed in the thread groove 15 , and a gasket 13 is sleeved on the outside of the fixing bolt 14 .
