Abstract
The utility model discloses an explosion-proof protecting cover of an angular polishing machine, comprising a front cover arranged on the machine and a protecting cover body arranged on the front cover, wherein the front end of the front cover is provided with a circular platform provided with the protecting cover body; the rear end of the protecting cover body is provided with a holding clamp which holds the circular platform and is tightly fixed by a fastener; and a limiting structure for limiting the rotating angle of the protecting cover body is arranged between the holding clamp and the circular platform. The explosion-proof protecting cover is simple in structure and convenient to install; when the impact force generated by explosion of a grinding wheel piece leads the protecting cover to rotate, clamping points on the protecting cover collide with an elastic pin on the front cover, so that the rotation of the protecting cover is stopped, and the rotating angle of the protecting cover can be controlled within certain range. Therefore, the explosion-proof protecting cover effectively solves the problem that the rotating angle of the protecting cover is too large when the grinding wheel piece explodes, plays a role in effectively protecting an operator, is rigid in positioning and safe and reliable.
Description
Technical field
The utility model relates to angle grinding machine accessory, the explosion-proof protective cover of particularly a kind of electric angle grinder.
Background technology
A very important examination point is arranged in the specification requirement of electric angle grinder, is exactly can not be greater than 90 degree in the anglec of rotation of designated environment lower grinding wheel sheet blast back protective cover.Common do not have the protective cover of special measure can not meet this condition certainly, just in case grinding wheel in use explodes, owing to the inhibition structure of protective cover not being rotated, the blast enormous motivation that produces can make protective cover 360 degree rotations, thereby might damaging to operating personnel, do not meet the requirement of safety, so just caused this product on market, not sell yet.
The utility model content
Problem to be solved in the utility model just provides the explosion-proof protective cover of a kind of electric angle grinder simple in structure, easy for installation, at the grinding wheel explosion time protective cover rotation is controlled in certain angle, effectively solved the excessive problem of the anglec of rotation of grinding wheel explosion time protective cover, safe and reliable.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme: the explosion-proof protective cover of a kind of electric angle grinder, comprise protecgulum that is installed on the machine and the shield body that is located on the protecgulum, it is characterized in that: the front end of protecgulum is provided with the round platform that shield body is installed, the rear end of shield body is provided with to embrace to block to embrace on round platform and by the securing member tightening and connects, and is provided with the position limiting structure of the restriction shield body anglec of rotation between armful card and round platform.
Further, described position limiting structure comprises protruding and is located on the side of embracing the stuck point on the card medial surface and being located at round platform and the corresponding spacer pin of stuck point that the side of round platform is provided with the pin-and-hole of plug-in mounting spacer pin.
Further, the side of described round platform is provided with the annular groove of placing stuck point, and pin-and-hole is located in the annular groove, and after the spacer pin plug-in mounting was gone into pin-and-hole, the top of spacer pin exceeded the bottom surface of annular groove and do not exceed frustum cone side.
Further, described spacer pin is a resilient key.
Further, described securing member is a screw bolt and nut, and the two ends of embracing card are provided with connector, and connector is provided with the through hole that installs bolt.
After adopting technique scheme; the utlity model has following advantage: when the impulsive force of grinding wheel blast makes the protective cover rotation; stuck point on the protective cover and the collision of the resilient key on the protecgulum; protective cover is stopped operating; so just the anglec of rotation of protective cover can be controlled within certain scope; efficiently solve the excessive problem of the anglec of rotation of grinding wheel explosion time protective cover, the operator is played effective protection, rigidity location, safe and reliable.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing:
Fig. 1 is the structural representation of a kind of embodiment of the utility model;
Fig. 2 is the structural representation of shield body;
Fig. 3 is the structural representation of protecgulum.
The specific embodiment
The structural representation of a kind of embodiment of the utility model as shown in Figures 1 to 3, the explosion-proof protective cover of a kind of electric angle grinder, comprise protecgulum 1 that is installed on the machine and the shield body 2 that is located on the protecgulum, the front end of protecgulum is provided with the round platform 11 that shield body is installed, the rear end of shield body is provided with to embrace blocks 21 armfuls on round platform and by securing member 3 tightenings connection, protrusion is provided with stuck point 22 on the card medial surface embracing, on the side of round platform, be provided with and the corresponding spacer pin 4 of stuck point, come in contact the anglec of rotation that limits shield body by stuck point and spacer pin, the side of round platform is provided with the pin-and-hole 111 of plug-in mounting spacer pin; Be provided with the annular groove 112 of placing stuck point on the side of round platform, pin-and-hole is located in the annular groove, and after the spacer pin plug-in mounting was gone into pin-and-hole, the top of spacer pin exceeded the bottom surface of annular groove and do not exceed frustum cone side.
In the foregoing description, spacer pin is a resilient key, buffering is arranged in the protective cover rotation process and stop the excessive effect of protective cover rotational angle; Securing member is a screw bolt and nut, and the two ends of embracing card are provided with connector 211, and connector is provided with the through hole 212 that installs bolt.
The tight obvolvent of embracing between card and the round platform is not exerted an influence for the stuck point that makes protrusion in addition, in the foregoing description, on frustum cone side, be provided with the annular groove outwards recessed cannelure can also be set on armful card, stuck point is located in the cannelure, after spacer pin inserts pin-and-hole, the side that exceeds round platform on the top of spacer pin, at this moment cannelure mainly is in order to prevent that spacer pin from exerting an influence to the tight obvolvent of embracing between card and the round platform, and such structure is just in time in contrast with the previous embodiment.
The utility model is simple in structure, easy for installation; when the impulsive force of grinding wheel blast makes the protective cover rotation; stuck point on the protective cover and the collision of the resilient key on the protecgulum; protective cover is stopped operating; so just the anglec of rotation of protective cover can be controlled within certain scope; efficiently solve the excessive problem of the anglec of rotation of grinding wheel explosion time protective cover, the operator is played effective protection, rigidity location, safe and reliable.
Except that above preferred embodiment, the utility model also has other embodiment, those skilled in the art can make various changes and distortion according to the utility model, only otherwise break away from spirit of the present utility model, all should belong to the defined scope of the utility model claims.
