Specific embodiment
As described below is only presently preferred embodiments of the present invention, is not intended to limit the scope of the present invention.
Embodiment: as shown in attached drawing 1,2,3,4,5,6,7 and attached drawing 8, a kind of high-intensitive five-pointed star with dismounting function
Foot, including outer pentagonal central block 1 and five stabilizer blades 2 further include that two sides are arranged on 1 five sides of the central block
The arc groove body plate 4 at 3 medial surface of clamping plate or more end position is arranged in clamping plate 3 at position, is arranged in the branch
Link slot 5 on 2 connecting pin of foot is arranged on the link slot 5 and fixed for link with the arc groove body plate 4
Arc pressuring plate 6 is arranged on 1 side of central block and is located between two clamping plates 3 and is used to support the company
The supporting block 7 of 5 upper layer groove body plate of access slot, and be arranged between two arc pressuring plates 6 and be used in the supporting block 7
Lower part be inserted into before stop the jack-up block 8 that supports upwards after limit, insertion.
In the present embodiment, totally five layers of the connection structure between the central block 1 and the stabilizer blade 2, by outside inside successively
It is that two clamping plates 3 are against on 5 inner top surface of link slot, two link slots 5 are hooked with the arc pressuring plate 6
Even, the most intermediate supporting block 7 receives the link slot 5 upwards and pushes, receives the jack-up block 8 downwards and above push away, final institute
Stating between central block 1 and the stabilizer blade 2 has convenient for disassembly and assembly, and the big advantage of installation rear support intensity.
The arc groove body plate 4 is equipped with the arc-shaped slot opened up upwards, the separate central block 1 on the arc-shaped slot
Side is equipped with for the protruding block 9 from the fixed arc pressuring plate 6 of outside limit, and 6 lower end of arc pressuring plate, which is equipped with, to be used
In the arcwall face slided on the arc-shaped slot.The block 8 that jacks up includes the vertical plane close to 1 side of central block,
And the arc top surface of upper end, 7 lower end of supporting block are equipped with for described vertical flat by being against in the stabilizer blade 2 insertion
Face upper type is with the lower limit plane 10 for limiting the fixed stabilizer blade 2 tilted down, in the rotation upwards of stabilizer blade 2
The middle supporting surface 11 being against after expansion in the vertical plane, and for allowing the arc in 2 rotary expansion of stabilizer blade
The upper arc surface 12 that top surface enters.
In the present embodiment, supporting block 7 lower end three acting surface failure sequence successively are as follows:
Firstly, 2 connecting pin of stabilizer blade upward, outer side wheel installation end downward, with 15 ° or so of angle of vertical angle, by institute
It states arc pressuring plate 6 to be inserted on the arc groove body plate 4, the medial plane and the lower limit plane for jacking up block 8 described at this time
10 contacts, the stabilizer blade 2 will not vacantly be fallen down at this time；
Secondly, 2 outside of stabilizer blade is up lifted, the arc top surface for jacking up block 8 starts to contact with the upper arc surface 12
Fitting；
Finally, when the rotation of stabilizer blade 2 is against on the side of the central block 1 to the end face of the link slot 5, the jack-up block
8 arc top surface rotates completely in the upper arc surface 12, and the medial plane for jacking up block 8 is against the middle supporting surface 11
On, so far, the supporting block 7 is pressed on the jack-up block 8, is stopped to the uptrending for jacking up block 8, as described
The supplement of support force between 1 side of 5 side of link slot and the central block, supports the central block 1 after the star base pressure-bearing
Sagging trend.
The protruding block 9 is equipped with for arc pressuring plate 6 described in the limited support in the stabilizer blade 2 insertion far from described
The limit plane 13 of 1 lateral surface of centerbody.Limiting slot 14, institute are formed between 9 lateral surface of protruding block and the arc-shaped slot
Arc pressuring plate 6 is stated to be equipped with by carrying out inserting mode for limiting the fixed branch being inserted into the limiting slot 14
The end gusset 15 of foot 2.
In the present embodiment, the stabilizer blade 2 keeps insertion when Unscrew with above-mentioned 15 ° or so angles, the jack-up
8 medial plane of block is against together with the lower limit plane 10, is restraining position at first, and the outside of the arc pressuring plate 6 is perpendicular
It is pressed in the limit plane 13 to plane, is restraining position at first, the last end gusset 15 is inserted in the limiting slot 14
On, for restraining position at the third after the stabilizer blade 2 insertion, it is inserted into the stabilizer blade 2 by the arc pressuring plate 6
To after 9 inside of the protruding block of the arc groove body plate 4, it can keep stable, avoid dropping out.
The protruding block 9 is equipped with for being against the arc pressuring plate 6 elevationally outward after 2 rotary expansion of stabilizer blade
Protruding block inner side plane in plane.
In the present embodiment, after 2 Unscrew of stabilizer blade, the plane elevationally outward of the arc pressuring plate 6 by
What is started contacts with the limit plane 13, keeps limit, is switched to and is against together with the protruding block inner side plane, guarantees base
This links structure, and then, 13 contact position of limit plane is the in-plane elevationally outward, the protruding block inside
The position that plane resists is the lower part of the plane elevationally outward.
7 upper surface of supporting block is equipped with insertion column 16, and 5 inner top surface of link slot, which is equipped with, passes through the insertion column
16 rotations are caught in mode with the insertion groove 17 for fixing when the stabilizer blade 2 is hanging.The insertion column 16 erects
To section be triangle, upper end be arc-shaped end, the supporting block 7 be equipped with and meanwhile connect the insertion column 16 and it is described in
Structure-reinforced piece 18 of heart block 1.The stabilizer blade 2 is equipped with for connecting the arc pressuring plate 6 and two for jacking up block 8
Main board 19.The arc pressuring plate 6 is equipped with structure aperture 20.
In the present embodiment, the arc pressuring plate 6 is linked with the arc groove body plate 4 and protruding block 9, the jack-up
Block 8 is withstood on upwards in the supporting block 7, and the stabilizer blade 2 when in use, and can guarantee certain support effect at this time, but strong
Spend far from enough, therefore the upper layer groove body plate of the link slot 5 is against on the side of the central block 1, is pressed in the supporting block 7
Upper surface on, this ensures that enough support strengths, if the upper layer groove body plate of the link slot 5 is not broken, upper layer
Continuous and effective when support construction, similarly, the arc pressuring plate 6 and protruding block 9 it is not broken if, lower end links structure
It is also continuous and effective.
Wherein, the main board 19 axially penetrates through the entire stabilizer blade 2, and 2 main body of stabilizer blade is inverted U, the main body
Plate 19 guarantees the arc pressuring plate 6 and jacks up the installation strength of block 8, i.e., the described main board 19 not when, the arc connects
Fishplate bar 6 can also be guaranteed by top and 5 connection type of link slot it is above-mentioned link effect, but intensity be obviously it is inadequate,
Therefore the main board 19 is used for connection reinforcement, guarantees the arc pressuring plate 6 and jacks up the mounting stability of block 8.
Embodiments of the present invention are explained in detail above in conjunction with attached drawing, but the present invention is not limited to above-mentioned embodiment party
Formula within the scope of knowledge possessed by those of ordinary skill in the art can also be before not departing from present inventive concept
It puts and makes various modifications.These be all without creative modification, as long as in scope of the presently claimed invention all by
To the protection of Patent Law.
