Specific implementation mode
There is a covering plate structure for blocking draining pump in the downside of the washing machine of existing market, and cover board with cover board support by matching
It closes, realizes on-off action.The fit system of cover board and cover board support is usually rotary shaft structure.Rotary shaft structure user switch is suitable
Freely, but the production of shaft and circular trough assembly is more difficult, and after-sales service dismounting is more difficult, and disassembly process easily generates the structure
Damage increases repair, use cost.
The present invention is directed to deficiency in the prior art, provides a kind of drainage pump of washing machine cover board support structure, passes through cunning
Being detachably fixed for cover board is realized in the mating connection of track slot and shaft, by designing protrusion on the inside of sliding-rail groove, can be achieved at the same time
The installation and positioning of countershaft simplify the structure composition of cover board support, increase structural strength, while facilitating the dismounting of cover board,
The damage of cover board and cover board support is reduced, repair and use cost are reduced.
Technical scheme of the present invention will be clearly and completely described by specific implementation mode below.Obviously, it is retouched
The embodiment stated is only a part of the embodiment of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, originally
The every other embodiment that field those of ordinary skill is obtained without creative efforts, belongs to the present invention
The range of protection.
Fig. 4 is referred to, as shown, a kind of drainage pump of washing machine cover board support structure, to be connected and fixed cover board 3, lid
One end of plate 3 is rotationally connected with the bottom of cover board support 2, and the other end is connected and fixed with 2 top of cover board support；Pass through rotating plate
Realize the switch of cover board.
3 bottom of cover board is extended with interconnecting piece 31, and the end of interconnecting piece 31 is arranged shaft 32,2 two bottom sides of cover board support at
Type has sliding-rail groove 21, and at least side of sliding-rail groove 21 is inwardly formed protrusion 22, and 21 width of sliding-rail groove of boss is less than shaft
32 diameter, shaft 32 are installed in the rotary axis groove 24 that 21 bottom of sliding-rail groove is cooperatively formed with protrusion 22.By the way that protrusion 22 is arranged,
Shaft 32 can be oriented to through sliding-rail groove 21 and move down, expression lobes 22, and protrusion 22 deforms after being squeezed to outside so that shaft 32 moves down
To rotary axis groove 24, while protrusion 22 resets so that shaft 32 is fixed in rotary axis groove 24, is realized the installation of shaft 32 and is determined
Position.Shaft 32 can be freely rotated in rotary axis groove 24, realize the switching function of cover board.When dismounting, shaft 32 is moved up, protrusion
22 be squeezed after deformed to outside so that shaft 32, which moves up, is detached from rotary axis groove 24, while protrusion 22 resets, and removes cover board, convenient
The dismounting of cover board.
Wherein, it is arranged in parallel with recessing groove 25 by sliding-rail groove 21, special-shaped muscle is formed between sliding-rail groove 21 and recessing groove 25
23, special-shaped muscle 23 is formed by bending protrusion 22 to 21 inside of sliding-rail groove.By the way that special-shaped muscle 23 and recessing groove 25 is arranged, cover board is dismounted
When, flexible deformation can be generated since protrusion 22 squeezes, facilitates the crimp and reset of protrusion 22, it is simple in construction, easy to disassemble and assemble,
And it is hardly damaged deformation, increase structural strength, improves service life.
In addition, at least one side wall of sliding-rail groove 21 can generate flexible deformation when squeezing, and the side wall is into sliding-rail groove 21
Side protrusion 22, sliding-rail groove 21 the protrusion 22 width be less than shaft diameter, shaft 32 through sliding-rail groove 21 be oriented to and install into
In rotary axis groove 24, protrusion realizes limit.
In addition, the outer ring of shaft 32 can also be elastic construction.In this way, when shaft 32 moves expression lobes 22, shaft 32
Outer ring can generate compressive deformation, facilitate being caught in and taking out for shaft 32.
Guide roller (not shown) is also rotatably provided in shaft 32.By the way that guide roller is arranged in shaft 32,
When shaft 32 is caught in, sliding friction can be converted to pivoting friction, reduction is caught in resistance, reduces friction damage.
The bottom of sliding-rail groove 21 is arcuate structure.It is preferred that the bottom of sliding-rail groove 21 is the semicircle knot concentric with shaft 32
Structure, the rotary axis groove 24 that protrusion is cooperatively formed with semicircular structure can 32 circumferential section of envelope shaft be more than 1/2.
It is preferred that the bottom of sliding-rail groove 21 is the semicircular structure concentric with shaft 32, protrusion is cooperatively formed with semicircular structure
24 envelope shaft of rotary axis groove, 32 circumference 3/4.It can realize the positioning after countershaft 32 is installed, specific envelope shaft 32
Partial area size is not limited.
The dismounting principle of the present invention is as follows：
By taking the semicircular structure of protrusion 22 and 21 bottom of sliding-rail groove cooperatively forms 3/4 circular configuration as an example.The shaft of cover board 3
32 are installed from top to bottom by sliding-rail groove 21, and installation to 22 position of protrusion on special-shaped muscle 23, protrusion 22 is squeezed by shaft 32
It is deformed to 25 side of recessing groove after pressure, makes shaft 32 by entering at the semicircular structure of 21 bottom of sliding-rail groove after protrusion 22, after
Protrusion on special-shaped muscle 23 resets, and shaft 32 is made to be fixed in 3/4 rotary axis groove 24, realizes installation positioning function, shaft 32 can be with
It is freely rotated in 3/4 rotary axis groove 24, realizes the switching function of cover board.Same principle when dismounting, shaft 32 are torn open upwards
Protrusion 22 is squeezed when unloading deforms to 25 side of recessing groove, and shaft 32 leaves 3/4 circular trough of 21 bottom of sliding-rail groove, realizes
Disassembling function.
The invention discloses a kind of drainage pump of washing machine cover board support structures, are connected by the cooperation of sliding-rail groove 21 and shaft
It connects, realizes being detachably fixed for cover board.By the way that in 21 inside design protrusion of sliding-rail groove, the shaft 32 of cover board can be led through sliding-rail groove 21
To and install in the rotary axis groove 24 that the bottom of sliding-rail groove 21 is cooperatively formed with protrusion 22, protrusion 22 realizes the limit of countershaft 32
Position, while realizing the installation and positioning of countershaft 32, the structure composition of cover board support is simplified, structural strength is increased.Simultaneously
Push up shaft 32 extrudable raised 22 so that shaft 32 is detached from rotary axis groove 24, facilitates the dismounting of cover board, and it is pair to reduce dismounting
The damage of cover board and cover board support reduces repair and use cost, and convenient for the switch of cover board.
When dismounting shaft 32 expression lobes 22 make its generate flexible deformation, reduce dismounting when shaft 32 with protrusion 22 squeeze
Crushing is hindered, and the service life of structure is increased.
In addition, by the way that guide roller is arranged in shaft 32, when shaft 32 is caught in, sliding friction can be converted to rolling
Friction, reduction are caught in resistance, reduce friction damage.
The foregoing description of the disclosed embodiments enables those skilled in the art to implement or use the present invention.
Various modifications to these embodiments will be apparent to those skilled in the art, as defined herein
General Principle can be realized in other embodiments without departing from the spirit or scope of the present invention.Therefore, of the invention
It is not intended to be limited to the embodiments shown herein, and is to fit to and the principles and novel features disclosed herein phase one
The widest range caused.
