Description
Technical Field
The utility model belongs to the technical field of the stirring technique and specifically relates to a first quick assembly disassembly structure stirs is related to.
Background
Some large mixers are transported after the mixer head and the mixer are detached, and some mixer heads are difficult to detach or easily hurt the mixer after being detached. Referring to fig. 1, an original mixing head dismounting structure includes an output shaft, an outer cone and a threaded portion which are integrally formed. It is easy to know from fig. 1 that the screw thread portion M1 can be taken out by rotating the external stirring shaft, but the rotation engaging force between the two sides of the outer cone M2 and the external stirring shaft is very large and is difficult to rotate, which ensures that the stirring shaft is not easy to separate from the output shaft, but also causes great difficulty in disassembling the stirring head.
2 strands of friction force exist simultaneously in original dismouting structure: the conical surface of the outer cone of the output shaft and the conical surface of the inner hole of the shaft head of the stirring shaft are tightly attached to form a friction force, and the end surface of the thread after the internal thread and the external thread are screwed tightly forms another friction force due to thread fastening. The 2 friction forces exist simultaneously and do not mutually give rise to the problem that the threaded connection cannot be loosened and is extremely difficult to loosen, and sometimes the problem that the internal thread and the external thread are seized up is caused.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is to provide a stirring head quick assembly disassembly structure.
In order to solve the technical problem, the utility model discloses a technical scheme as follows: first quick assembly disassembly structure stirs installs in the outside hollow shaft that is equipped with first screw thread, has the mixer output shaft, the hollow shaft outside is equipped with the anti-lock nut with first screw thread matched with, mixer output shaft bottom is fixed with the toper excircle body, toper excircle body bottom fixedly connected with dabber, the dabber overcoat is equipped with assorted external screw thread axle sleeve with it, external screw thread axle sleeve outside is equipped with the second screw thread, the dabber bottom is equipped with spacing retaining ring, leave first space between terminal surface and the spacing retaining ring up end under the external screw thread axle sleeve.
Furthermore, the equal axial of the hole of external screw thread axle sleeve and the excircle of dabber is equipped with the keyway, the gomphosis has the parallel key in the keyway.
Further, a second gap is reserved between the external thread shaft sleeve and the mandrel.
Furthermore, an annular groove is formed between the output shaft of the stirring machine and the conical outer circular body, and a split type clamping ring protruding out of the annular groove is sleeved in the annular groove.
To sum up, the utility model discloses compare in the first dismouting structure of traditional stirring beneficial effect is:
the utility model discloses can realize the quick assembly disassembly process of stirring head, the frictional force that exists after the conical surface of having avoided the outer cone of output shaft and the conical surface of (mixing) shaft spindle nose hole are hugged closely, and the threaded end face after only remaining inside and outside screw thread is screwed up because the frictional force that screw thread fastening exists avoids inside and outside screw thread to appear "stinging dead" problem, labour saving and time saving, and can not cause the harm to mixer or (mixing) shaft.
Drawings
The foregoing and other objects, features, and advantages of the invention will be apparent from the following detailed description taken in conjunction with the accompanying drawings.
FIG. 1 is a schematic view of an original stirring pump assembly;
FIG. 2 is a schematic view of the quick-release structure of the present invention;
FIG. 3 is a schematic structural view of the present invention after the stirring shaft is separated from the conical outer body;
fig. 4 is the schematic view of the connection between the mandrel and the external thread shaft sleeve of the present invention.
Wherein: 1. the novel stirrer comprises a stirrer output shaft, 2. an external hollow shaft, 3. a counter locking nut, 4. a split type snap ring, 5. a conical outer circular body, 6. a mandrel, 7. an external thread shaft sleeve, 8. a flat key, 9. a limiting retainer ring, 10. a first gap, 11. a key groove, 12. a second gap, 13. an annular groove, M1. a threaded part and M2. an external cone.
Detailed Description
In the following, the preferred embodiments of the present invention will be explained, and various changes and modifications can be made by workers without departing from the technical spirit of the present invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
The invention will be further described with reference to the accompanying figures 2 to 3: first quick assembly disassembly structure stirs, install in the outside is equipped with first screw thread hollow shaft 2 in, mixer output shaft 1 has, 2 outsides of hollow shaft are equipped with first screw thread matched with locking nut 3 that turns over, 1 bottom of mixer output shaft is fixed with toper excircle body 5, 5 bottom fixedly connected with dabber 6 of toper excircle body, 6 overcoat of dabber are equipped with assorted external screw thread axle sleeve 7 with it, external screw thread axle sleeve outside is equipped with the second screw thread, 6 bottoms of dabber are equipped with spacing retaining ring 9, leave first space 10 between terminal surface and the 9 up ends of spacing retaining ring under the external screw thread axle sleeve 7. The inner hole of the external thread shaft sleeve 7 and the excircle of the mandrel 6 are both axially provided with key grooves 11, and flat keys 8 are embedded in the key grooves 11. A second gap 12 is left between the external thread shaft sleeve 7 and the mandrel 6. An annular groove 13 is arranged between the output shaft 1 of the stirring machine and the conical excircle body 5, and a split type snap ring 4 protruding out of the annular groove 13 is sleeved in the annular groove 13.
The principle of use of the present invention is briefly explained with reference to fig. 2: in foretell stirring head quick assembly disassembly structure, because leave first space 10 between terminal surface and the spacing retaining ring 9 up end under the external screw thread axle sleeve 7, and because external screw thread axle sleeve 7 outside has the screw thread can with outside hollow shaft 2 looks block, so only need give 2 decurrent pressures of outside hollow shaft, can make outside hollow shaft and external screw thread axle sleeve 6 sink slightly together, and twist and move anti-lock nut 3 and can extrude split type snap ring 4 in the ring channel 13, thereby drive hollow shaft 2 and sink, outside hollow shaft 2 after sinking then no longer contacts with toper excircle body 5, the rotatory bite-force between toper excircle body 5 and outside hollow shaft 2 disappears, then can easily screw out external screw thread axle sleeve 6 and inside dabber 6.
