Abstract

The utility model provides an inserted blade assembling structure, particularly a blade group without complete correction or tenon alignment, which adopts a three-point positioning assembling structure. The blade group is composed of a plurality of blades, a main base of a wheel shaft, and an auxiliary cover of the wheel shaft. A positioning tenon handle which can be embedded and fit in a tenon groove of the main base of the wheel shaft bulges from the center of the blades. An upper side and a lower side of a trip backup plate are firmly locked between the main base of the wheel shaft and the auxiliary cover of the wheel shaft by being symmetrical with a groove to form the firm locking of the three-point positioning tenon so as to reduce the volume and to easily fix the locking.

Description

Embedded flabellum composite structure

Technical field

The utility model provides a kind of embedded flabellum composite structure, the special three points location mode that adopts comprises that in conjunction with trip plural blade central authorities protrude a location lug handle and can coincide and embed tongue-and-groove on the wheel shaft seat of honour, the upper and lower both sides of one trip backup plate symmetrical grooves lock is against between the wheel shaft seat of honour and the secondary lid of wheel shaft and forms 33 D planes, be able to firmly sealedly easily, and have the effect of exempting to proofread and correct fully tenon.

Background technique

In existing technology, as shown in Figure 1, known flabellum 1 central axle 10 volumes are big and the contraposition combination is difficult, only slightly deviation promptly can cause the rotation stress deflection, the loosening phenomenons such as fracture or the inclined to one side power of motor that all will cause of arbitrary screw, and the loosening deflection that is caused of flabellum 1 is acutely rocked and is easily made the motor overload heating, when serious motor coil is burnt.

Summary of the invention

Main purpose of the present utility model is the defective that overcomes above-mentioned prior art, and a kind of embedded flabellum composite structure is provided, and this flabellum group comprises that 3 of the secondary lid formations of blade, the wheel shaft seat of honour and the wheel shaft of plural number are firm sealed, and has the effect of exempting to proofread and correct fully to tenon.

The purpose of this utility model realizes that by following technical proposals a kind of embedded flabellum composite structure provided by the utility model comprises:

One flabellum group, its comprise plural blade insert be embedded in be able between the wheel shaft seat of honour and the secondary lid of wheel shaft the three points location tenon really lock by and firm;

One plural blade, central authorities protrude a location lug handle and can coincide and embed tongue-and-groove on the wheel shaft seat of honour;

One location lug handle tail end has the screw locking of through hole by the wheel shaft pair side of covering, and location lug handle both sides respectively extend to the trip backup plate, form symmetrical grooves up and down between this trip backup plate, can kiss to connect the mutual clamping interlock of square gear block down of the secondary lid of this wheel shaft;

The secondary lid of one wheel shaft, central authorities have the annular distance can be to being placed on the wheel shaft seat of honour;

The one wheel shaft seat of honour, extend on every side groove and this trip backup plate mutually interlocking lean on, and by the secondary lid of this wheel shaft downwards and the clamping of the wheel shaft seat of honour sealed.

For further being familiar with and understanding structure of the present utility model and effect thereof, it is as follows to be elaborated for embodiment's conjunction with figs. now, so that it is understood more.

Embodiment

The utility model provides a kind of embedded flabellum composite structure, see also Fig. 2 to shown in Figure 4, among the figure, flabellum group 2 is by plural blade 3,4,6 formations of the secondary lid of the wheel shaft seat of honour 5 and wheel shaft, plural number blade 3, the 4th, slotting being embedded between the wheel shaft seat of honour 5 and the secondary lid 6 of wheel shaft, the secondary lid of its wheel shaft 6 central authorities have the annular distance 60 can be to being placed on the wheel shaft seat of honour 5, finishing the true lock of three points location tenon leans on, by this plural number blade 3, a location lug handle 30 is protruded in 4 central authorities, 40 can coincide embeds tongue-and-groove 50 on the wheel shaft seat of honour 5,51, its location lug handle 30,40 tail ends have through hole 300,400 screws 7 by the secondary lid of wheel shaft 6 tops, 8 run through this through hole 300,400 and with

nut

70,80 lockings, at location lug handle 30,40 both sides respectively extend to trip backup plate 31,32,41,42, this trip backup plate 31,32,41, vertically be H type shape between 42 and form symmetrical grooves 33 up and down, 34,43,44 trips, can kiss and connect 6 times square gear block 61 mutual clamping interlocks of the secondary lid of this wheel shaft, extend to groove 52 and this trip backup plate 31 around the wheel shaft seat of honour 5,32,41,42 phase interlockings are by making trip backup plate 31,32,41,42 form mutually also ring bodies, and by the secondary lid 6 of this wheel shaft downwards and 5 clampings of the wheel shaft seat of honour sealed.

Seeing also shown in Figure 5ly, is by the secondary lid of the wheel shaft seat of honour 5 and this wheel shaft trip backup plate 31,32,41,42 that pressing should 3,4 extensions of plural number blade 6 about it to be fitted with the plane three points location fully to reach firm effect among the figure.

For making the utility model show its progressive and practicability more, now with commonly use that to do a comparative analysis as follows:

Commonly use defective

1, flabellum central axle volume is difficult for than big and contraposition combination, and only slightly deviation promptly can cause rotation stress to be partial to.

2, the loosening phenomenons such as fracture or the inclined to one side power of motor that all will cause of arbitrary screw.

3, looseningly cause deflection acutely to rock, easily the overload heating is burnt motor coil.

4, danger in the use is arranged.

5, cause unexpected the generation easily.

The utility model advantage

1, blade integral reduction in bulk.

2, can reduce the motor burden.

3, assembling is easy, easy for installation.

4, shorten combination, adopt three points location and lean on into 3 D plane, and the advantage of exempting to proofread and correct is fully arranged in conjunction with driving fit lock in both sides about the trip.

5, have Security and practicability.

6, tool height technological progress.

Though embodiment of the present utility model has disclosed as above, yet it is not in order to limiting the utility model, anyly has the knack of this application engineer, in not breaking away from spirit and scope of the present utility model, the various equivalence of being done changes and modifies, and all should still belong in the scope that the utility model patent contains.Take a broad view of above-mentionedly, structure of the present utility model, feature can provide a kind of using effect preferable hoist cylinder structure really, and can make it have use value and progressive really.
