Detailed Description
The following description is only a preferred embodiment of the present invention, and does not limit the scope of the present invention.
Referring to fig. 1-4, a quick-mounting structure for a protecting cover of a grass trimmer comprises a housing 10 accommodating a driving mechanism and a protecting cover 20 detachably connected with the housing 10, the grass trimmer of the embodiment is an electric grass trimmer, the driving mechanism is a motor, the housing 10 is formed by mutually splicing a left housing and a right housing, the motor is fixedly installed in the housing 10, the protecting cover 20 is integrally formed, and the housing 10 is provided with a rotary connecting part 17 for connecting a handle.
The output shaft 11 of the motor extends out of the shell 10 from the bottom of the shell 10, a sliding block 12 is formed on one side, located on the shell 10, of the extending out of the output shaft 11, a slot 21 is formed in the protective cover 20 and used for the sliding block 12 to be transversely inserted into, an avoiding groove 22 matched with the output shaft 11 of the motor is formed in the slot 21, the avoiding groove 22 is formed in the bottom of the slot 21, and the avoiding groove 22 is used for preventing the bottom of the slot 21 from interfering with the output shaft 11 of the motor when the sliding block 12 of the shell 10 is inserted into the slot 21 of the protective cover 20 in a sliding mode.
The front end of the sliding block 12 on the casing 10 is provided with a first clamping block 13, the rear end of the sliding block 12 on the casing 10 is provided with a second clamping opening 14, the inner side of the slot 21 on the protective cover 20 is provided with a first clamping opening 23 matched with the first clamping block 13, and the outer side of the slot 21 on the protective cover 20 is provided with a second clamping block 24 matched with the second clamping opening 14. When the sliding block 12 of the housing 10 is slidably inserted into the slot 21 of the protective cover 20, the first clamping block 13 is in clamping fit with the first bayonet 23, and the second clamping block 24 is in clamping fit with the second bayonet 14, so that the insertion fit between the housing 10 and the protective cover 20 is more stable.
The shell 10 is provided with screw holes 15, the protective cover 20 is provided with through holes 25 corresponding to the screw holes 15, and after the protective cover 20 is inserted in the shell 10 in place, the protective cover 20 passes through the through holes 25 through screws 30 and is screwed into the screw holes 15 to be fixedly connected with the shell 10. The main function of the screw 30 is not to fasten the housing 10 and the shield 20, but to limit the sliding fit relationship between the sliding block 12 of the housing 10 and the slot 21 of the shield 20, so that the housing 10 does not slide relative to the shield 20.
An elastic retaining block 26 is arranged at the bottom of the sliding groove 21 on the protective cover 20, and a retaining groove 16 matched with the elastic retaining block 26 is arranged at the bottom of the sliding block 12 on the shell 10. When the sliding block 12 of the housing 10 is slidably inserted into the slot 21 of the protective cover 20, the elastic stopping block 26 is clamped into the stopping groove 16, and the sliding block 12 of the housing 10 is limited to slide out of the slot 21 of the protective cover 20 within the elastic action range of the elastic stopping block 26, so that after the screw 30 is removed, the protective cover 20 cannot be separated from the housing 10 immediately along with the removal of the screw 30, and the protective cover 20 can be removed from the housing 10 only by overcoming the elastic force of the elastic stopping block 26 to remove the clamping fit relationship between the elastic stopping block 26 and the stopping groove 16, thereby ensuring the safety and reliability of the removal of the protective cover 20 and facilitating the screwing in of the screw 30 when the protective cover 20 is installed.
The above is only the preferred embodiment of the present invention, so all the equivalent changes or modifications made by the structure, features and principles in accordance with the claims of the present invention are included in the claims of the present invention.
