Abstract
The utility model aims to provide an improved angle grinder, which has a simple structure and longer service life, runs stably and reliably, and is free from leakage of lubricating oil when working. For achieving the effects, the angle grinder comprises a machine body, wherein the front end of the machine body is provided with a head shell; a motor is arranged in the machine body; a key hole is formed in the head shell; a self-locking pin and a self-locking button arranged at the upper end of the self-locking pin are arranged in the key hole; a compression spring is sleeved at the periphery of the self-locking pin; the self-locking pin passes through the key hole, and extends into the head shell; the lower end of the compression spring in the key hole is provided with an inner groove; and an O-shaped sealing ring is arranged in the inner groove. Due to the adoption of the technical scheme, the lubricating oil in a gearbox can be prevented from leaking outwards, the existing resources are used fully, and the working stability of the gearbox is improved. Moreover, external dust can be prevented from entering the head shell, so that normal work of the gearbox and other components is ensured.
Description
Technical field
The utility model relates to a kind of electric tool, particularly a kind of improved 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 will dismantle after the output shaft locking earlier, very inconvenience again.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, cause 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 structure complicated of electric angle grinder integral body, whole cost rises.
The utility model content
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, and a kind of improved electric angle grinder is provided, and is simple in structure, but working stability, reliable the leakage of lubricating oil can not take place, the service life of having improved product when work.
In order to reach described effect, a kind of improved electric angle grinder of the utility model, comprise 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 described 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, the lock pin periphery is socketed with the compression spring, and described self-lock pin passes this through hole and stretches in the head capsule; Be positioned at compression spring lower end in this key hole and be provided with inside groove, be provided with the O RunddichtringO in the inside groove.
Preferably, the top of O RunddichtringO also is lined with plain cushion in the described 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.
Preferably, described plain cushion is an annular.
A kind of improved electric angle grinder that the utility model provides, owing to adopted described technical scheme, increased O-ring seals at self-locking device and head capsule cooperation place, therefore can prevent that the lubricating oil of gear-box from leaking on the one hand, guarantee that existing resource is fully used, improve the job stability of gear-box.Can prevent that on the other hand external dust from entering in the head capsule, to guarantee the operate as normal of gear-box and other parts.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing:
Fig. 1 is the overall structure schematic diagram of a kind of improved electric angle grinder of the utility model.
Fig. 2 is the key hole part enlarged diagram of a kind of improved electric angle grinder of the utility model.
The specific embodiment
As Fig. 1 and shown in Figure 2, a kind of improved electric angle grinder of the utility model, comprise 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 described 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, self-lock pin 5 peripheries are socketed with compression spring 7, and described 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 described inside groove, and compression spring 7 is pressed on the plain cushion 9.Described plain cushion 9 is an annular.
In use, the mechanical realization of electric angle grinder itself is comparatively tight, is difficult for into dust, but 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 that oil leak and dust enter.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 enter head capsule 2.The top of O RunddichtringO 8 also is lined with plain cushion 9 in the described 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.
The above only is a specific embodiment of the utility model, but technical characterictic of the present utility model is not limited thereto, any those skilled in the art is in field of the present utility model, and variation of being done or modification all are encompassed among the claim of the present utility model.
