Abstract

An angle grinding machine preventing lubrication oil from leaking out comprises a machine body. The front end of the machine body is provided with a head casing. A motor is arranged in the machine body. A press key hole is arranged in the head casing. A self-locking pin and a self-locking press button arranged at the upper end of the self-locking pin are arranged in the press key hole. A compression spring is sleeved outside the self-locking pin. The self-locking pin penetrates through a through hole and extends into the head casing. A position in the press key hole, located at the lower end of the compression spring, is provided with an inner groove. An O-shaped sealing ring is arranged in the inner groove. Due to the fact that the O-shaped sealing ring is arranged on the matching portion between the self-locking device and the head casing, the angle grinding machine has the advantages of preventing the lubrication oil in a gear box from leaking out, ensuring existing resources to be fully utilized, improving work stability of the gear box, and preventing dust outside from entering the head casing to ensure normal operation of the gear box and other components.

Description

Prevent the electric angle grinder that lubricating oil leaks
Technical field
The utility model relates to a kind of electric tool, particularly a kind of electric angle grinder.
Background technology
Electric angle grinder in the prior art, mill and grinding wheel are installed on the output shaft, when mill and grinding wheel wearing and tearing occur and when needing to change, must be earlier with dismantling again after the output shaft locking, unusual inconvenience.For this reason, also designed the self-locking device of output shaft in the prior art.Yet existing this device is when cooperating with head capsule; Do not design supporting hermetically-sealed construction; So, the lubricating oil that is used for gear-box in the head capsule just can overflow from the gap between the two, causes the waste of resource; External dust also can enter in the head capsule from this gap, influences the operate as normal of gear-box and other parts.And if adopt other encapsulating method, then can cause the whole structure complicated of electric angle grinder, whole cost rises.
Summary of the invention
The purpose of the utility model is to overcome the deficiency of above-mentioned prior art, and a kind of electric angle grinder that prevents that lubricating oil from leaking is provided, and is simple in structure, but the leakage of lubricating oil can not take place when work working stability, reliable.
To achieve these goals, the technical scheme taked of the utility model is:
A kind of electric angle grinder that prevents that lubricating oil from leaking comprises body; The body front end is provided with head capsule; Also be provided with motor in the body, be provided with key hole in the said head capsule, be provided with self-lock pin and the locking press button of being located at the self-lock pin upper end in the key hole; Lock pin is with the compression spring outward, and said self-lock pin passes this through hole and stretches in the head capsule; Should be provided with inside groove by being positioned at compression spring lower end in the chain hole, be provided with the O RunddichtringO in the inside groove.
The top of O RunddichtringO also is lined with plain cushion in the said inside groove, and the compression spring is pressed on the plain cushion.The plain cushion of this structure setting can prevent to compress the compression of spring to O-ring seals, thereby O-ring seals is played a protective role, and further guarantees the job stability of head capsule inner part.The compression spring can directly not be compressed on the O RunddichtringO like this, has avoided the O RunddichtringO to be damaged.
Said plain cushion is an annular.
The beneficial effect of the utility model: increased O-ring seals at self-locking device and head capsule cooperation place, therefore on the one hand can prevent that the lubricating oil of gear-box from leaking, guaranteed that existing resource is fully used, improved the job stability of gear-box.Can prevent that on the other hand external dust from getting in the head capsule, to guarantee the operate as normal of gear-box and other parts.
Description of drawings
Fig. 1 is the overall structure decomposing schematic representation of the utility model electric angle grinder.
Fig. 2 is the key hole part enlarged diagram of the utility model electric angle grinder.
The specific embodiment
Like Fig. 1 and shown in Figure 2, a kind of electric angle grinder that prevents that lubricating oil from leaking of the utility model comprises body 1; Body 1 front end is provided with head capsule 2; Also be provided with motor 3 in the body 1, be provided with key hole 4 in the said head capsule 2, be provided with self-lock pin 5 and the locking press button 6 of being located at self-lock pin 5 upper ends in the key hole 4; The self-lock pin 5 outer compression springs 7 that are with, said self-lock pin 5 passes this through hole and stretches in the head capsule 2; Be positioned at compression spring 7 lower ends in this key hole 4 and be provided with inside groove, be provided with O RunddichtringO 8 in the inside groove.The top of O RunddichtringO 8 also is lined with plain cushion 9 in the said inside groove, and compression spring 7 is pressed on the plain cushion 9.Said plain cushion 9 is an annular.
In use, the mechanical realization of electric angle grinder itself is comparatively tight, is difficult for into dust, still at key hole 4 positions, owing to there are the grooves in the straight-through head capsule 2 to exist, therefore tends to take place the incident of oil leak and dust entering.Therefore in key hole 4, be positioned at compression spring 7 lower ends and be provided with inside groove, be provided with O RunddichtringO 8 in the inside groove.The leakage and the dust that so just can prevent lubricating oil get into head capsule 2.The top of O RunddichtringO 8 also is lined with plain cushion 9 in the said inside groove, and compression spring 7 is pressed on the plain cushion 9.Like this O RunddichtringO 8 has also been played the effect of a protection.So just can improve the whole service life of electric angle grinder.
