Specific embodiment
In order to keep the purposes, technical schemes and advantages of the embodiment of the present invention clearer, implement below in conjunction with the present invention
Technical solution in example carries out clear, complete description, it is clear that and described embodiment is section Example of the invention, and
It is not all of embodiment.Based on the embodiment of the present invention, those of ordinary skill in the art are not before making the creative labor
Every other embodiment obtained is put, protection scope of the present invention is belonged to.
As Figure 1-Figure 4, while refering to Fig. 7-Fig. 8, the present invention provides a kind of pivot structures, including for holding in the palm loading
The supporting plate 10 of product, the limiting bracket 20 for being rotatably provided in 10 one end of supporting plate, the shaft 30 for being rotatably provided in 10 other end of supporting plate, limit
Position bracket 20 and shaft 30 are L-shaped；It is understood that limiting bracket 20 and shaft 30 are equivalent to stator, 10 phase of supporting plate
When in rotor, supporting plate 10 can do spinning movement between limit between 20 and shaft 30, i.e. three is located on same axis.
Supporting plate 10 is provided with rotation stop pin 11 close to the side of limiting bracket 20, and rotation stop pin 11 prolongs far from one end of supporting plate 10
It extends on limiting bracket 20, is provided with limiting slot 26 at position corresponding with one end that rotation stop pin 11 stretches out on limiting bracket 20,
Limiting slot 26 and rotation stop pin 11 rotate supporting plate can only within the scope of horizontal and vertical 90 degree；Wherein, 11 He of rotation stop pin
The effect of limiting slot 26 is the rotational steps for limiting supporting plate 10, and in the present embodiment, the rotating range of rotation stop pin 11 is located at second
In the range of quadrant, i.e. the rotating range of supporting plate 10 is only limitted to the second quadrant, it should be noted that the second quadrant mentioned here
It is the direction based on attached drawing 3 and attached drawing 8.
Limiting bracket 20 includes rack body 21, passes through the setting of bearing 25 on rack body 21 for connecting with supporting plate 10
Connector 22, the inside of rack body 21 is set and forms the push top 23 of self-locking structure with connector 22, be arranged in bracket master
The spring 24 of self-lock force is provided between body 21 and push top 23 and for push top 23；Wherein it is possible to which what is understood is connector 22 and supporting plate
Belong between 10 and be fixedly connected, be rotatablely connected with rack body 21, the mode of rotation connection is to be also possible to lead to by bearing
Cross sleeve；Push top 23 inside rack body 21 is set it is to be understood that the place that rack body 21 is contacted with connector 22
It is provided with blind hole, push top 23 is disposed therein, and can be slid back and forth wherein, but is not able to rotate, when supporting plate 10 is stood
When, the promotion of push top 23 is withstood connector 22 by spring 24, is realized and is locked, prevent supporting plate 10 from oneself rotating, when artificial rotation
When supporting plate 10,23 reverse extrusions of having a haircut, the compression of spring 24 are realized unlock by the rotation of 22 stress of connector, this to lock and unlock
Relationship can pass through push top 23 and connector 22 contact position be arranged it is mutual corresponding protrusion and recess.
As shown in Fig. 5-Fig. 6, shaft 30 includes shaft lower casing 31, the rotary shaft cover 32 being mounted on shaft lower casing 31, fixes
On supporting plate 10 and with shaft lower casing 31 rotation connection first rotating shaft 40, for be fixed on wall or equipment supporter and with
Second shaft 50 of the rotation connection of shaft lower casing 31.
In the present embodiment, shaft 30, which both can be used as stator, can also be used as rotor, and when as stator, i.e., supporting plate 10 revolves
Turning, when as rotor, i.e. the second shaft 50 is used as stator, and whole device rotates on level side's line as rotor, also, by
The enclosed construction that shaft lower casing 31 and rotary shaft cover 32 are constituted, first rotating shaft 40 and 50 Hide All of the second shaft are got up, made
Overall appearance is more attractive.
Supporting plate 10 is square, and supporting plate 10 and limiting bracket 20 and the tie point of shaft 30 are located at two of supporting plate 10 together
The vertex on side；In the present embodiment, it can be understood as, the rotary shaft of supporting plate 10 is overlapped on one side with its.
Supporting plate 10 is square or circle, and supporting plate 10 and limiting bracket 20 and the tie point of shaft 30 are located in supporting plate 10
On heart line；In the present embodiment, unlike aforementioned, the rotary shaft of supporting plate 10 at the center line on, when supporting plate 10 rotation extremely
When horizontality, the upper weight limit for the article that can be held can be higher.
As shown in Fig. 5-Fig. 6, first rotating shaft 40 includes that one end is fixed on the other end and the rotation of shaft lower casing 31 on supporting plate 10
The first rotor 41 of connection, the first rotor elastic slice 42 covered on the first rotor 41, and matched with the first rotor 41 by screw thread
Merge the first rotor fixture nut 43 the first rotor 41 being fixed on shaft lower casing 31；Second shaft 50 includes the second rotor
51, the second rotor elastic slice 52 and the second rotor fixture nut 53, the structure of the second shaft 50 are identical as the structure of first rotating shaft 40.
One end and supporting plate 10 fixed limiting bracket 20 are provided on the other end and are capable of fixing in bottom surface or metope or set
Standby upper fixation bracket.
It is understood that ought when in use, if being not provided with bracket, since the arm of force is too long, supporting plate 10 cannot be born
How much weight, and when supporting plate 10 is rotated, the limiting bracket 20 as stator must be fixed；The fixation bracket
It can be in face of different scene demands with sucker, with multiple stabilizer blades or with pipe clamp.
As shown in Figs. 7-8, it is provided with several rounded array distributions on one side close to connector 22 in push top 23
Protrusion, recess is provided on connector 22 with raised corresponding position, and protrusion can be engaged with recess；Protrusion and recess can also be
Wavy shaped configuration, working principle it is to be understood that two mutual out-of-flatnesses face, when relatively rotating, wave crest and
It staggeredly advances between trough, i.e., when the wave crest in push top 23 has corresponded to the trough on connector 22, then overall length is minimum between the two,
It is now in locking state, when the wave crest on connector 22 is moved at the wave crest in push top 23, the two overall length is elongated, that is, pushes away
First 23 move back, and spring 24 is compressed, and are now in unlocked state, corresponding, and the protrusion in push top 23 can be understood as wave crest,
Recess on connector 22 can be understood as trough.
It should be understood that for those of ordinary skills, it can be modified or changed according to the above description,
And all these modifications and variations should all belong to the protection domain of appended claims of the present invention.
