One side of the supporting plate 10, which is close to the limiting bracket 20, is provided with a stop pin 11, one end of the stop pin 11, which is far away from the supporting plate 10, extends to the limiting bracket 20, a limiting groove 26 is arranged on the limiting bracket 20 at a position corresponding to the extending end of the stop pin 11, and the limiting groove 26 and the stop pin 11 enable the supporting plate to rotate within a range of ninety degrees horizontally and vertically; the rotation stopping pin 11 and the limiting groove 26 are used to limit the rotation range of the pallet 10, and in this embodiment, the rotation range of the rotation stopping pin 11 is located in the second quadrant, that is, the rotation range of the pallet 10 is limited to the second quadrant, and it should be noted that the second quadrant is based on the directions of fig. 3 and fig. 8.
The limit bracket 20 comprises a bracket main body 21, a connector 22 which is arranged on the bracket main body 21 through a bearing 25 and is used for being connected with the supporting plate 10, a push head 23 which is arranged inside the bracket main body 21 and forms a self-locking structure with the connector 22, and a spring 24 which is arranged between the bracket main body 21 and the push head 23 and provides self-locking force for the push head 23; it can be understood that the connector 22 is fixedly connected with the supporting plate 10 and is rotationally connected with the bracket main body 21, and the rotational connection mode is through a bearing or a sleeve; the push head 23 arranged in the bracket main body 21 can be understood that a blind hole is formed in a place where the bracket main body 21 is in contact with the connector 22, the push head 23 is arranged in the blind hole and can slide back and forth in the blind hole, but cannot rotate, when the supporting plate 10 is kept still, the spring 24 pushes the push head 23 to push against the connector 22, locking is achieved, the supporting plate 10 is prevented from rotating, when the supporting plate 10 is manually rotated, the connector 22 is forced to rotate so as to reversely squeeze the push head 23, the spring 24 is compressed, unlocking is achieved, and the locking and unlocking relationship can be achieved by arranging a protrusion and a recess which correspond to each other at the contact position of the push head 23 and the connector 22.
As shown in fig. 5 to 6, the rotary shaft 30 includes a rotary shaft lower case 31, a rotary shaft cover 32 mounted on the rotary shaft lower case 31, a first rotary shaft 40 fixed on the pallet 10 and rotatably connected with the rotary shaft lower case 31, and a second rotary shaft 50 for fixing on a wall or a device bracket and rotatably connected with the rotary shaft lower case 31.
In this embodiment, the shaft 30 may be used as either a stator or a rotor, and when used as a stator, i.e., the supporting plate 10 rotates, and when used as a rotor, i.e., the second shaft 50 is used as a stator, and the whole device rotates as a rotor on a horizontal line, and the closed structure formed by the shaft lower case 31 and the shaft cover 32 conceals the first shaft 40 and the second shaft 50 entirely, thereby making the whole appearance more attractive.
The supporting plate 10 is square, and the connection point of the supporting plate 10, the limiting bracket 20 and the rotating shaft 30 is positioned at the vertexes of two identical sides of the supporting plate 10; in the present embodiment, it is understood that the rotation axis of the pallet 10 coincides with one side thereof.
The supporting plate 10 is square or round, and the connection point of the supporting plate 10, the limiting bracket 20 and the rotating shaft 30 is positioned on the central line of the supporting plate 10; in the present embodiment, unlike the foregoing, the upper limit of the weight of the article that can be held is higher when the pallet 10 is rotated to the horizontal state with the rotation axis of the pallet 10 on the center line thereof.
As shown in fig. 5 to 6, the first rotary shaft 40 includes a first rotor 41 having one end fixed to the supporting plate 10 and the other end rotatably coupled to the rotary shaft lower case 31, a first rotor elastic piece 42 sleeved on the first rotor 41, and a first rotor fixing nut 43 screwed with the first rotor 41 and fixing the first rotor 41 to the rotary shaft lower case 31; the second rotating shaft 50 includes a second rotor 51, a second rotor elastic piece 52 and a second rotor fixing nut 53, and the structure of the second rotating shaft 50 is the same as that of the first rotating shaft 40.
One end of the limiting bracket 20 is fixed with the supporting plate 10, and the other end of the limiting bracket is provided with a fixed bracket which can be fixed on the bottom surface or the wall surface or equipment.
It will be appreciated that when in use, if no bracket is provided, the pallet 10 will not bear much weight due to the excessive length of the arm of force, and the spacing bracket 20, which is a stator, must be secured as the pallet 10 rotates; the fixing bracket can be provided with suction cups, with a plurality of supporting feet or with a pipe clamp facing different scene requirements.
As shown in fig. 7-8, a plurality of protrusions distributed in a circular array are arranged on one surface of the push head 23, which is close to the connector 22, and a recess is arranged on the connector 22, which corresponds to the protrusions, and the protrusions can be engaged with the recesses; the protrusion and the recess may be in a wave structure, and the working principle of the protrusion and the recess may be that two surfaces which are uneven with each other are alternately moved between the wave crest and the wave trough when the two surfaces are relatively rotated, that is, when the wave crest on the push head 23 corresponds to the wave trough on the connector 22, the total length between the two surfaces is minimum, at this time, the protrusion and the wave trough are in a locking state, when the wave crest on the connector 22 moves to the wave crest on the push head 23, the total length of the two surfaces is longer, that is, the push head 23 moves backwards, the spring 24 is compressed, at this time, at the unlocking state, the protrusion on the push head 23 may be understood as the wave crest, and the recess on the connector 22 may be understood as the wave trough.
It will be understood that modifications and variations will be apparent to those skilled in the art from the foregoing description, and it is intended that all such modifications and variations be included within the scope of the following claims.
