technical field

The utility model relates to the field of engines, in particular to a special tool for quickly tightening an oil pan screw plug.

Background technique

At present, with the continuous update of on-site equipment, the process is more perfect, and the production cycle is also speeding up. In the oil discharge process of the test machine section, workers need to use a wrench to unscrew the plug of the oil pan to release the oil. Tighten the oil pan plug, because the oil pan plug is at the lowest point on the side of the oil pan, and because the design of the engine oil pan plug is different, the oil pan plug used by the same engine may use an inner hexagonal plug or Hexagonal screw plug, so two different tools will be prepared in the process of oil release in the test machine section. It is inconvenient for post workers to use traditional wrench to tighten, and it needs to swing the wrench many times to achieve the tightening effect, resulting in high labor intensity. , Difficult operation and low work efficiency.

Utility model content

The utility model aims at the problems of high labor intensity, difficult operation and low work efficiency in tightening the screw plug of the oil pan in the existing process of draining the oil in the test machine section, and provides a special tool for quickly tightening the screw plug of the oil pan . The tool includes a hexagon rod and a sleeve that can be matched with the inner hexagonal bolt and the outer hexagonal bolt. It can be switched freely when tightening different types of oil pan plugs. At the same time, there is a handle cover in the middle. During the screw plugging process, the handle sleeve can be held tightly to play a stable role, and the oil pan screw plug can be tightened by rotating the stepped handle with the hand lever, which solves the problem that the existing tools need to swing the wrench multiple times to achieve the tightening effect.

In order to achieve the above purpose, the technical scheme adopted in this paper is as follows:

A special tool for quickly tightening the screw plug of the oil pan, which is characterized in that it includes a stepped handle, a sleeve, a handle cover, a lock nut, and a handle, and the upper part of the step handle is installed with a circular or square handle position, the middle part of the ladder handle is a round rod, the lower part of the round rod is provided with a handle cover limit end, the lower part of the ladder handle is a hexagonal rod, the upper part of the hexagonal rod is provided with threads, and the lower part is provided with a sleeve limit end. position end; the lock nut is provided with a magnetic block; the sleeve is connected with the hexagon rod; the handle cover is connected with the round rod; the lock nut and the hex rod are threaded Mating connection; the handle bars are respectively connected with the handle bar installation positions.

Further, a round hole is provided under the installation position of the handle bar.

Further, four threaded holes are provided on the installation position of the handle; the handle is a round or square rod, and one end of the handle is provided with threads; the handle and the installation position of the handle are connected by a screw connected in a cross-shaped manner.

Further, the sleeve is a hollow sleeve, the upper part of the sleeve is a hexagonal hole matching the hexagonal rod, and the lower part is an outer hexagonal bolt sleeve.

Further, the handle cover is made of aluminum alloy.

Compared with the prior art, the utility model has advantages and beneficial effects as follows:

1. The tool is equipped with a hexagonal rod and a sleeve that can be matched with the inner hexagonal bolt and the outer hexagonal bolt. By setting the sleeve limit end and thread on the hexagonal rod and cooperating with the lock nut, the lock nut There is also a magnetic block on the top, so that the sleeve can move up and down on the hexagonal rod and fixed, and can be switched freely when tightening different types of oil pan plugs. The handle cover can be held firmly in the middle to play a stabilizing role, and the oil pan screw plug can be loosened by rotating the stepped handle with the hand lever.

2. There is a round hole under the installation position of the hand rod on the ladder handle. When using in a relatively compact environment, the hand rod can be removed, and an iron rod with a suitable length can be used through the round hole.

3. The tool is simple and convenient in structure, simple in operation, labor-saving, low in manufacturing cost and high in work efficiency.

Detailed ways

The utility model will be described in further detail below in conjunction with specific embodiments. It should be emphasized that the following descriptions are only illustrative, not intended to limit the scope of the present utility model and its application.

As shown in Figures 1 to 5, the special tool for quickly tightening the screw plug of the oil pan is characterized in that it includes a stepped handle 1, a sleeve 2, a handle cover 3, a lock nut 4, and a handle 5, The upper part of the ladder handle is a round or square handle mounting position 6, and a round hole 7 is provided below the handle mounting position 6, and the handle 5 can be disassembled when used in a relatively compact environment. Select an iron rod with a suitable length to pass through the round hole 7 and then use it. Four threaded holes 8 are provided on the handle mounting position 6 for installing the handle 5; the handle 5 is a round or square rod , one end of the handle bar is provided with threads; the handle bar 5 and the handle bar installation position 6 are connected by a threaded screw, and after the connection, they form a cross shape. The middle part of the ladder handle 1 is a round bar 9, and the round bar The lower part of 9 is provided with a handle cover limit end 10, which is used to limit the handle cover 3 on the round rod 9 to prevent the handle cover 3 from moving up and down. Bolt, the upper part of the hexagonal rod 11 is provided with a thread 12, which is used to cooperate with the lock nut 4, and the lower part is provided with a sleeve limit end 13, which is used to limit the sleeve 2, and the sleeve 2 is tightened by the lock screw 4 ; The lock nut 4 is provided with a magnetic block 14, which is used to hold the sleeve 2 to prevent it from moving when using a hexagonal rod; the sleeve 2 is a hollow sleeve, and the upper part of the sleeve 2 is connected to the hexagonal rod 11 matching hexagonal holes, the lower part is an outer hexagonal bolt sleeve; the handle cover 3 is made of aluminum alloy, which is lightweight and the magnetic block 14 cannot be adsorbed; the sleeve 2 is connected with the hexagonal rod 11; The handle cover 3 is connected with the round rod 9; the lock nut 4 is connected with the hexagonal rod 11 through the screw thread 12; the handle rod 5 is connected with the handle rod installation position 6 respectively.
