Abstract

The utility model relates to a quick leak stopping tool used in engine run, comprising a front portion and a handle part, wherein the front section of the front portion has a step-shaped snap ring matched with the neck of the inner spring plate arranged inside the oil supply/return pipe joint of an engine; the part of the front section of the front portion below the snap ring is matched with the inner seal ring of the oil supply/return pipe joint of the engine; the rear section of the front portion is provided with a slide bushing; the outside diameter of the slide bushing is more than the outside diameter of the snap ring and is less than the maximum expanding inside diameter of the inner spring plate. The leak stopping tool has a simple structure and convenient use; moreover, an operator can easily complete assembly and disassembly, thereby increasing work efficiency.

Description

A kind of motor break-in instantaneous leaking-stopping instrument

Technical field

The utility model belongs to motor mounting technology field, is specifically related to motor break-in leak stoppage tool.

Background technique

The assembling of many kinds motor is the main trend that current motor is made, because the type difference of producing, the structure of its oil inlet pipe is not quite similar.In period of adjustment,, need often to change the requirement that leak stoppage tool satisfies the motor break-in at motor because the structure of oil inlet pipe is not quite similar.

Existing break-in stand adopts original plug to carry out, and its no expansion gear is when plug takes out, because the elastomeric plastics circle return effect in the interface cause plug dismounting difficulty, and the time is longer.

Summary of the invention

The purpose of this utility model is to overcome the above-mentioned defective that prior art exists, and a kind of motor break-in instantaneous leaking-stopping instrument is provided, and also can take out fast with the leakage that can block gasoline quickly and efficiently, satisfies the break-in requirement of motor.

Goal of the invention of the present utility model adopts following scheme to realize:

A kind of motor break-in instantaneous leaking-stopping instrument, comprise head and shank, the head leading portion has a step-like snap ring, advance with motor, the draw-in groove of the interior cover shell fragment in the return tube interface cooperates, the following position of the snap ring of head leading portion is advanced with motor, return tube interface inner seal ring cooperates: the head back segment is provided with sliding sleeve, sliding sleeve external diameter approximately greater than the external diameter of snap ring, and less than the maximum spreading internal diameter of interior cover shell fragment.

When using this instrument, head injected motor advances, the return tube interface, the following position of the snap ring of head leading portion is advanced with motor, return tube interface inner seal ring cooperates the realization sealing, interior cover shell fragment in the snap ring elder generation spreading interface, overlap in the draw-in groove of shell fragment in sliding into then, make head can not withdraw from interface, this instrument promptly is in place, and motor can begin break-in; When break-in finishes, to lower slider, the interior cover shell fragment by in the effect spreading interface of sliding sleeve front end contacts with snap ring until the sliding sleeve front end, props up sliding sleeve then with the sliding sleeve on the instrument, firmly outwards can take out this instrument apace like a cork by handle.

Advantage of the present utility model is as follows: this leak stoppage tool is simple, and is easy to use, and the operator can be fast, mount and dismount like a cork, increases work efficiency.

Description of drawings

Fig. 1 is the structural representation of this instantaneous leaking-stopping instrument;

Fig. 2 is the user mode figure of this instantaneous leaking-stopping instrument when leak stopping;

Fig. 3 is the phase diagram of this instantaneous leaking-stopping instrument when taking out.

Embodiment

Referring to Fig. 1, the motor break-in comprises the head 1 of front end, the shank 3 and middle sliding sleeve 2 three parts of rear end with the instantaneous leaking-stopping instrument, wherein the head leading portion has a step-like snap ring 4, the head back segment is provided with sliding sleeve 2, sliding sleeve 2 external diameter ∮ A approximately greater than the external diameter ∮ B of snap ring 4, and less than motor advance, the maximum spreading internal diameter of interior cover shell fragment in the return tube interface.

Referring to Fig. 2 and Fig. 3, when connect motor advance, when the return tube interface needs leak stopping, the workman inserts interface 5 according to the instantaneous leaking-stopping instrument that advances, the size of return tube interface is chosen corresponding specification, seal ring 6 in the snap ring 4 following positions of the head leading portion of this leak stoppage tool and the interface 5 cooperates and prevents the gasoline leakage, simultaneously, snap ring 4 snaps in the draw-in groove of the interior cover shell fragment 7 in the interface, interior cover shell fragment 7 shrinks and withstands snap ring 4, prevent that operating oil pressure from making leak stoppage tool landing outgoing interface, reaches leak stopping and begin break-in; When break-in finishes, to lower slider sliding sleeve 2, cover shell fragment 7 spreadings in the front end ∮ A by sliding sleeve 2 makes, (∮ A＞∮ B) can easily take out plug apace.

In actual production, need manufacture and design the instrument series of all size according to the size of different type of machines, different size and different apertures oil inlet and oil return pipe connection mouth, satisfy that different motors advance, the leak stopping of return tube interface.

Claims

1. motor break-in instantaneous leaking-stopping instrument, comprise head and shank, the head leading portion has a step-like snap ring, advances with motor, the draw-in groove of the interior cover shell fragment in the return tube interface cooperates, and the following position of the snap ring of head leading portion is advanced with motor, return tube interface inner seal ring cooperates; It is characterized in that: the head back segment is provided with sliding sleeve, sliding sleeve external diameter approximately greater than the external diameter of snap ring, and less than the maximum spreading internal diameter of interior cover shell fragment.
