Description

But casing and lawn mower of quick assembly disassembly cover body

[ technical field ] A

The invention relates to a machine shell capable of quickly disassembling and assembling a cover body and a mower, and belongs to the field of garden tools.

[ background ] A method for producing a semiconductor device

Garden tools such as lawn mowers, lawn mowers and the like are increasingly used in daily life and work, because such garden tools are generally provided with cutting tools, and a large amount of grass clippings are also generated in the process of mowing or mowing, a protective cover is usually installed on such garden tools, so that the effect of protecting the personal safety of users can be achieved, and the phenomenon that the grass clippings are splashed onto human bodies can be reduced. But the protection casing owing to often can touch some barriers, damages easily, and the frequency of dismouting is higher relatively, and some users also are used to when not using this type of instrument, demolish the protection casing moreover to convenient storage, occupation space is little, because these circumstances, so the protection casing needs often to be dismantled and the installation.

In the prior art, the protective covers of the grass mower or the grass trimmer are integrally formed with the machine shell or are fixed on the machine shell through screws, when the protective covers are assembled or disassembled, special tools are required to be used for installation or disassembly, the operation is very inconvenient, and the screw holes are seriously abraded after the screw holes are disassembled/assembled for many times, so that the grass trimmer is poor in durability. The protective cover can touch various obstacles in actual operation, and sometimes when the protective cover is greatly impacted, the edge part can be deformed, so that the buckle is separated.

[ summary of the invention ]

The present invention provides a housing and a lawn mower capable of quickly assembling and disassembling a cover, which can reduce the deformation of the cover to increase the stability of the fastening between the cover and the main housing.

To solve the technical problem, the invention adopts the following technical scheme:

the utility model provides a but casing of quick assembly disassembly cover body, includes the main casing body and establishes the cover body on the main casing body, main casing side is equipped with the assembly recess, the cover body is including being used for pegging graft and spiral-lock to the cartridge flange in the assembly recess, the both ends of cartridge flange are equipped with the lug respectively, be equipped with two spacing jacks in the assembly recess, two lugs correspond and insert two spacing jacks are in order to prevent the cover body is out of shape and is expanded outward.

The invention has the following beneficial effects: according to the invention, the cover body is installed on the main shell in an inserting and buckling mode, wherein the inserting is in a translation inserting mode, and the cover body is buckled by utilizing a buckle after being inserted.

In addition, because the mode of lock exists the problem that breaks away from easily, and break away from often because the cover body takes place to warp, the cover body can often touch some barriers when actual operation, and in order to reduce the cover body and produce the deformation because the collision, the both ends of cartridge flange are equipped with the lug respectively, be equipped with two spacing jacks in the assembly recess, two lugs correspond insert two spacing jacks in order to prevent the cover body warp and expand outward, because the cover body is out of shape, the both ends of cartridge flange are the position that the deflection is great, have restricted the both ends of cartridge flange and have warp, also reduced the deformation of cartridge flange to the at utmost, because the cover body just is the cartridge flange with main casing body fitting portion, reduce this partial deformation, just also increased the stability of being connected of cover body and main casing body.
