A kind of Demountable blade component
Technical field
The utility model relates to the technical field of soy bean milk making machine parts, especially relates to a kind of Demountable blade component.
Background technology
At present, soy bean milk making machine is widely used.The crushing knife of the soy bean milk making machine on the existing market generally is riveted joint or is welded on the machine shaft, can not free-handly take off, and easy like this causing cleaned the dead angle, and the accident of crushing knife incised wound hand occurs easily, has potential safety hazard.
The Chinese patent notification number is that CN201374989Y discloses a kind of dismountable soybean milk maker cutter, comprises that soy bean milk making machine and motor for soymilk cabin extend to the motor shaft in the cup body of soymilkgrinder, and the motor shaft end sets firmly reducing mechanism by retaining mechanism.Wherein, the snap close piece that is threaded on the axle head screw rod of retaining mechanism by reducing mechanism suit motor shaft forms.And snap close piece is the nut that reducing mechanism is set in the motor shaft end screw rod and is spirally connected with this screw rod.Although this soybean milk maker cutter is detachable, solved the cleaning Dead Core Problems of general crushing knife of soymilk machine on the market, but its retaining mechanism processed complex, its snap close piece that is threaded the snap close tension probably occurs and need to be by the situation of instrument dismounting, so still there is the problem of dismounting inconvenience in this soybean milk maker cutter.
The utility model content
For the shortcoming of prior art, the utility model provides a kind of Demountable blade component, and is simple in structure, need not just can realize dismounting by work, is user-friendly to.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of Demountable blade component, comprise cutter shaft and blade, it is characterized in that: described blade is fixed on the blade holder, and described cutter shaft upper end is provided with spire, blade holder is provided with screw-thread bush, and blade holder is fixed on cutter shaft by the spiral of spire and screw-thread bush.
Alternatively, described spire is the flat axle of fried dough twist, and screw-thread bush is the shaped grooved screw-thread bush of a word, and the shaped grooved screw-thread bush of a described word cooperates with the flat axle spiral of fried dough twist.
Preferably, the diameter of the diameter of the flat axle of described fried dough twist and the shaped grooved screw-thread bush of a word is suitable, makes the fit structure of the two more reliable and more stable.
Alternatively, described blade is riveted or is fixedly welded on the blade holder.
Alternatively, the bearing of described blade holder and cutter shaft is provided with support member, and the supports support blade holder also limits its position, stops the axially-movable of blade holder.
Alternatively, described support member and cutter shaft are one-body molded.
Alternatively, described support member is jump ring, and cutter shaft is provided with for the fixing stopper slot of jump ring.The employing jump ring cooperates as support member with stopper slot, and cutter shaft need not to make a boss specially and supports, and processing cost is low, and is easy to use.
Preferably, described jump ring is E type jump ring.
Compared with prior art, the beneficial effects of the utility model are:
The utility model Demountable blade component is by being provided with screw-thread bush in blade holder, the cutter shaft spiral that makes it to be provided with the upper end spire cooperates, utilize blade self gravitation and this fried dough twist formula structural design, make blade holder overcome pressure angle to realize the spiral assembling of blade holder and cutter shaft, when blade rotates, because its direction of rotation is opposite with the hand of spiral of spire, so blade can revolve more fastening and more fastening and can not fly out.Simple and the easy cleaning of this structure processing need not just can realize dismounting by work, is user-friendly to.

The specific embodiment
Below in conjunction with the specific embodiment the utility model is further described.
Such as Fig. 1 to the embodiment that Figure 7 shows that the utility model Demountable blade component, comprise cutter shaft 10 and blade 20, blade 20 is by riveting or being fixedly welded on the blade holder 30, cutter shaft 10 upper ends are provided with spire 11, blade holder 30 is provided with screw-thread bush 31, and blade holder 30 is fixed on cutter shaft 10 by the spiral of spire 11 with screw-thread bush 31.In the present embodiment, spire 11 is the flat axle of fried dough twist, and screw-thread bush 31 is the shaped grooved screw-thread bush of a word.Wherein, the diameter of the diameter of the flat axle of fried dough twist and the shaped grooved screw-thread bush of a word is suitable, makes the fit structure of the two more reliable and more stable.
In order to stop the axially-movable of blade holder 30, blade holder 30 is provided with support member with the bearing of cutter shaft 10, and supports support blade holder 30 also limits its position.Wherein, support member and cutter shaft 10 are one-body molded.Support member also can be jump ring 40, and jump ring 40 cooperates with stopper slot on being located at cutter shaft 10.Employing jump ring 40 cooperates as support member with stopper slot, and cutter shaft 10 need not to make a boss specially and supports, and processing cost is low, and is easy to use.The jump ring 40 of present embodiment is E type jump ring.
This Demountable blade component is by being provided with screw-thread bush 31 in blade holder 30, cutter shaft 10 spirals that make it to be provided with the upper end spire 11 cooperate, utilize blade 20 self gravitations and this fried dough twist formula structural design, make blade holder 30 overcome pressure angle to realize the spiral assembling of blade holder 30 and cutter shaft 10, when blade 20 rotation, because its direction of rotation is opposite with the hand of spiral of spire 11, so blade 20 can revolve more fastening and more fastening and can not fly out.Simple and the easy cleaning of this structure processing need not just can realize dismounting by work, is user-friendly to.
