Detailed Description
An exemplary embodiment of the present utility model will be described more fully hereinafter with reference to the accompanying drawings, in which embodiments of the utility model are shown. Unless defined otherwise, technical or scientific terms used herein should be given the ordinary meaning as understood by one of ordinary skill in the art.
As shown in fig. 1, the rotation and locking device of the micro-miniature cradle head of the present embodiment includes a locked turbine 1, a locked shaft 2, locking balls 3, a locking shaft 4, and a locking hand wheel 5.
As shown in fig. 3, the locked turbine 1 includes an upper sleeve 101 and a lower disk 102 integrally connected, and the inner wall of the center hole of the lower disk 102 is provided with an arc groove 103. Four second mounting holes 7 are uniformly formed in the upper sleeve 101 of the locked turbine 1 along the circumference, and when the whole device is not used, four jacking bolts penetrate into the second mounting holes 7 to fixedly connect the locked shaft 2 with the locked turbine 1, so that the locked turbine is convenient to store and transport.
As shown in fig. 4, the locked shaft 2 is slidably sleeved inside the locked turbine 1, and the clearance should be moderate to ensure that the locked shaft 2 can freely rotate in the locked turbine 1. Four ball holes 201 are uniformly formed in the middle of the locked shaft 2 along the circumference and correspond to the circular arc grooves 103 in position, and the four ball holes 201 are communicated with the inner cavity of the middle lower part of the locked shaft 2.
As shown in fig. 5, the locking balls 3 are placed in the circular arc grooves 103 of the locked turbine 1 and the ball holes 201 of the locked shaft 2, the number of which is 4, and the positions of which are movable.
As shown in fig. 2, the locking shaft 4 is positioned in the inner cavity of the middle lower part of the locked shaft 2, and the locking shaft 4 is connected with the locked shaft 2 through threads. The upper outer circumference of the locking shaft 4 is provided with a thread section 401 and an inclined surface section 402, the thread section 401 is connected with the inner wall of the locked shaft 2 through threads, and the inclined surface section 402 is used for pushing the locking balls 3 to move and extruding the locking balls 3.
As shown in fig. 6, the locking hand wheel 5 is sleeved in the bottom end inner cavity of the locking shaft 4, four first mounting holes 6 are uniformly formed in the lower portion of the locking shaft 4 along the circumference, and the locking hand wheel 5 and the locking shaft 4 are fixedly connected through penetrating four jacking bolts into the first mounting holes 6.
In this embodiment, the clearance between the locking ball 3 and the ball hole 201 on the locked shaft 2 should be as small as possible, so as to ensure the firmness and stability during locking, and no rotation occurs between the locked turbine 1 and the locked shaft 2. The radius of the circular arc groove 103 of the locked turbine 1 should be smaller than the radius of the locking ball 3 to prevent the locking ball 3 from falling out. The inclined surface section 402 on the locking shaft 4 for pushing the locking balls 3 to move should be selected to be at a proper angle, so that the locking balls 3 can move along the radial direction of the locking shaft 4. When the locking shaft 4 moves downwards to loosen the locking balls 3, the moving position is limited, so that the locking balls 3 are prevented from falling into the central hole of the locked shaft 2.
The locked turbine 1 and the locked shaft 2 can rotate freely, and unlocking and locking are realized through the cooperation of the locked turbine and the locking ball 3. The locking hand wheel 5 is rotated, and the locking shaft 4 moves up and down in the locked shaft 2. When the locking shaft 4 moves upwards, the inclined surface section 402 on the locking shaft 4 continuously presses the locking ball 3 to realize locking between the locked turbine 1 and the locked shaft 2; when the locking shaft 4 moves downwards, the inclined surface section 402 on the locking shaft 4 is far away from the locking ball 3, so that the locking ball 3 is loosened, unlocking between the locked turbine 1 and the locked shaft 2 is realized, and the locking ball and the locking shaft can rotate randomly.
The rotation and locking device of the microminiature holder can realize arbitrary rotation and locking between the locked turbine 1 and the locked shaft 2, and has the advantages of small and exquisite appearance, simple structure, low manufacturing cost, convenient operation and the like.
