Abstract
The utility model provides a detachable connecting structure of an outer cover of an air filter, and belongs to the technical field of garden machines. The detachable connecting structure of the outer cover of the air filter solves the problems that an existing outer cover of an air filter is connected with a base of the air filter through screws, tools are needed when disassembly is carried out, and disassembling efficiency is low. The detachable connecting structure of the outer cover of the air filter comprises a locking knob, wherein an inserting hole and a lock hole are correspondingly formed in the outer cover of the air filter and the base of the air filter respectively, the head portion of the locking knob penetrates through the inserting hole and the lock hole in sequence, a baffle is arranged on the tail portion of the locking knob, the baffle is blocked to be on the outer side of the outer cover, and a non-return structure is further arranged between the locking knob and the base, and is used for preventing the locking knob from being pulled away from the lock hole after the locking knob is rotated by a certain angle. The detachable connecting structure of the outer cover of the air filter is simple in structure and convenient to clamp and press; when the locking knob is inserted into the inserting hole and the lock hole, only 90-degree rotation is carried out, fixed connection between the outer cover of the air filter and the base of the air filter can be achieved, separation between the outer cover of the air filter and the base of the air filter can be achieved through backward 90-degree rotation, and cleaning of dust of the base of the air filter can be convenient.
Description
Technical field
The utility model belongs to the graden machine technical field, relates to a kind of air filter of mowing machine, particularly a kind of structure that removably connects of air filter outer cover.
Background technique
Air filter, it is air-strainer, the effect of air-strainer is to prevent the grains of sand and dust inflow engine gas handling system, cylinder, piston and the piston ring of maintenance motor, make the engine fuel sufficient combustion working life of prolongation motor, in order to avoid except the wearing and tearing of dust to motor, and then guarantee effective performance of engine power and the prolongation in working life, reduce simultaneously the pollution to environment.
In machine is used in the small-sized gardens such as mowing machine, air filter comprises air filter outer cover, air filter base and air filter assembly, owing to pasting for a long time ground work, dust, weeds etc. are most easily to enter in the filter core of air filter assembly, therefore often need dismounting air filter outer cover to clear up, more renew cartridge also needs outer cover is pulled down simultaneously.Traditional air filter outer cover is fixed on the air filter base by fastening pieces such as screws, and dismounting needs instrument and needs rotation could dismantle for a long time lower air filter outer cover, and often removal efficiency is not high.
Summary of the invention
The purpose of this utility model is to be connected screw with the air filter base for existing above-mentioned air filter outer cover to connect, the problem of dismounting inconvenience, and proposed a kind of simple for structure, the structure that removably connects of the air filter outer cover that can instantaneously dismantle, install.
The purpose of this utility model can realize by following technical proposal:
A kind of structure that removably connects of air filter outer cover, it is characterized in that, it comprises locking knob, on air filter outer cover and base respectively correspondence offer jack and lockhole, the head of described locking knob passes jack and lockhole successively, the afterbody of locking knob is provided with baffle plate, and baffle plate is blocked in the outside of outer cover, also is provided with between described locking knob and base to prevent that after locking knob rotates to an angle locking knob from detaching the non-return structure of lockhole.
Described air filter outer cover and base stick together, and locking knob intert to connect air filter outer cover and base, two respectively by baffle plate and non-return structure make the air filter outer cover and the base both sides stressed press fit fixing.
In the structure that removably connects of above-mentioned a kind of air filter outer cover, described non-return structure comprises the stopper that is arranged on the locking knob head, and the inner edge place that is positioned at lockhole on base is provided with the block corresponding with above-mentioned stopper, is kept off by block when stopper goes to the block place.
In the structure that removably connects of above-mentioned a kind of air filter outer cover, also be provided with pressing plate on described locking knob, pressing plate and divides with stopper the both sides that are located at base between baffle plate and stopper.But the displacement that described pressing plate limiting locking knob makes progress in the lockhole footpath reduces rocking of locking knob.
In the structure that removably connects of above-mentioned a kind of air filter outer cover, described block is two opposed arc plate muscle, forms socket between two arc plate muscle.Described stopper can be passed socket, and after 90-degree rotation, stopper is kept off by block.
In the structure that removably connects of above-mentioned a kind of air filter outer cover, the monolithic arc plate muscle of described block is the spiral lift structure.Stopper realizes by rotation in the process of non-return, climbs along spiral rising surface of contact simultaneously, eliminates the gap in the year of stopper and block, produces screwing force, the locking locking knob.
In the structure that removably connects of above-mentioned a kind of air filter outer cover, described pressing plate and baffle plate are all in the form of annular discs.
In the structure that removably connects of above-mentioned a kind of air filter outer cover, also be provided with the elastic wings limit on described locking knob, the elastic wings limit is positioned at the opposite side of outer cover with respect to baffle plate, and wing limit is obliquely installed, one is connected with locking knob, and the other end perk is also kept off by outer cover.For locking knob after making dismounting is unlikely to drop, generally the baffle plate on locking knob and elastic wings limit make locking knob be fixed on outer cover jointly, and need to detach locking knob fully the time, should apply of the wing limit perk active force, make it that elastic strain and inwardly extruding occur, therefore the wing limit of perk is not namely kept off by outer cover, and locking knob can detach from an end of jack.
In the structure that removably connects of above-mentioned a kind of air filter outer cover, the both wings limit opposite tilt setting on described elastic wings limit is arrow shaped.
In the structure that removably connects of above-mentioned a kind of air filter outer cover, be provided with dividing plate between described outer cover and base, dividing plate is connected with outer cover.Described dividing plate can first be used for the shaft core position of positioning jack and lockhole when not inserting locking knob, the insertion of being convenient to locking knob connects.
Compared with prior art, this apparatus structure is simple, card is pressed convenient, locking knob is inserted in jack and lockhole, only need rotate to an angle and to realize being connected of air filter outer cover and air filter base, contrary revolve and the air filter outer cover is separated with the air filter base, the dustiness of being convenient to clear up the air filter base reaches more renew cartridge.
