Abstract
The utility model discloses a drop prevention structure for a screw component of a protective cover of an angle grinder. The drop prevention structure comprises a protective cover provided with a hoop, a screw and a nut, wherein the screw is in rotating connection with a first installation lug of the hoop through a limiting mechanism; and the nut is fixed on a second installation lug of the hoop. With the adoption of the structure, the screw and the nut are limited on the two installation lugs and cannot drop from the hoop of the protective cover, so that the safety is guaranteed.
Description
Technical field
The utility model relates to electric angle grinder.
Background technology
European Union rises on October 1st, 2011 and comes into effect new machinery standard, wherein in the standard of diagonal angle mill clear and definite proposition new demand: as Fig. 1, when rotating or dismantle protective cover 1, screw 3 on the protective cover and nut 4 cannot break away from the gear shift cover of shield body or machine.The mounting ear of protective cover all adopts the plain screw nut that mounting ear 12 connections are fastening now, does not meet the new machinery standard requirement of European Union.
The utility model content
Technical problem to be solved in the utility model just provides a kind of screw assembly anti-drop structure of electric angle grinder protective cover, this structure is when rotating or dismantle protective cover, screw on the protective cover can not come off, and is simple in structure, fundamentally guaranteed operator's security.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: a kind of screw assembly anti-drop structure of electric angle grinder protective cover, comprise the protective cover that is provided with anchor ear, screw and nut, it is characterized in that: on first mounting ear of anchor ear, described nut is fixed on second mounting ear of anchor ear described screw by the position-limit mechanism switching.Adopt this structure to make screw and nut be limited on two mounting ears and can not come off, guaranteed safety from the anchor ear of protective cover.
Preferably, described nut is fixed on the medial surface of second mounting ear.
Preferably, described nut is fixed on the lateral surface of second mounting ear.
Preferably, described nut is welded on second mounting ear.
Preferably, described position-limit mechanism is the collar that is fixed on the screw root, and described collar is located at the medial surface of first mounting ear, thus with screw now on first mounting ear and do not come off.
Preferably, described position-limit mechanism is the collar that is fixed on screw end; When nut was fixed on the medial surface of second mounting ear, described collar was located at the lateral surface of second mounting ear; When nut was fixed on the lateral surface of second mounting ear, described collar was located at the outside of nut.
A kind of screw assembly anti-drop structure of electric angle grinder protective cover, comprise the protective cover that is provided with anchor ear, screw and nut, it is characterized in that: described screw end is fixed with collar, collar is located at the lateral surface of second mounting ear, and described nut is installed on the screw and is between the lateral surface and collar of second mounting ear.
On first mounting ear of anchor ear, nut then is fixed on second mounting ear of anchor ear the utility model screw by the position-limit mechanism switching.Adopt this structure to make screw and nut be limited on two mounting ears and can not come off, guaranteed safety from the anchor ear of protective cover.
