Detailed Description
In order to facilitate an understanding of the utility model, the utility model will be described more fully and in detail below with reference to the accompanying drawings and preferred embodiments, but the scope of the utility model is not limited to the specific embodiments below.
It should be particularly noted that when an element is referred to as being "fixed to, connected to or communicated with" another element, it can be directly fixed to, connected to or communicated with the other element or indirectly fixed to, connected to or communicated with the other element through other intermediate connecting components.
Unless otherwise defined, all terms of art used hereinafter have the same meaning as commonly understood by one of ordinary skill in the art. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the scope of the present invention.
Example 1
As shown in fig. 1 and 2, the centrifuge rotor 1 adapted to various motor shafts in the present embodiment includes a rotor 1, and a plurality of centrifuge grooves 12 for placing centrifuge tubes are provided on the rotor 1. The rotor 1 is provided with a mounting hole 11 used for being connected with a motor shaft and a mounting groove used for arranging the limiting flange 2, and the mounting groove is arranged on the upper portion of the mounting hole 11. The limiting flange 2 is annular, the limiting flange 2 is fixed in the mounting groove through a bolt 5, the upper end of the locking nut 3 penetrates through an inner hole 21 of the limiting flange 2, the lower end of the locking nut 3 is provided with a boss surface, and the radius of the boss surface is larger than that of the inner hole 21 of the limiting flange 2; the boss surface of the lock nut 3 is pressed against the step arranged on the rotor 1 at the upper part of the mounting hole 11, and the step is arranged between the mounting groove and the mounting hole 11.
In this embodiment, the motor shaft connected with the rotor 1 is an outer thread type, when the rotor 1 is installed on the motor shaft, the rotor 1 is firstly placed on the motor shaft, the motor shaft penetrates through the installation hole 11 of the rotor 1 to enter the installation groove, then the lock nut 3 is matched with the outer thread of the motor shaft in a threaded manner, and the lock nut 3 abuts against the step arranged on the rotor 1 on the upper portion of the installation hole 11, so that the rotor 1 and the motor shaft are fixed when the lock nut 3 is screwed down. The limiting flange 2 is sleeved, the limiting flange 2 and the rotor 1 are fixed by using the bolt 5, and the centrifugal rotor 1 can be driven by a motor shaft to perform centrifugal work. In this embodiment, when taking off rotor 1, owing to the existence of spacing flange 2, as long as loosen lock nut 3, under the restriction of spacing flange 2, lock nut 3 can drive rotor 1 and break away from the motor shaft together to realize quick dismantlement rotor 1.
Example 2
As shown in fig. 3 and 4, the centrifuge rotor 1 adapted to various motor shafts in this embodiment is different from embodiment 1 in that the limiting flange 2 is a circular plate, the bottom of the limiting flange 2 is provided with a protrusion 22, and the protrusion at the bottom of the limiting flange 2 is arranged in a step arranged on the rotor 1 at the upper part of the mounting hole 11; a through hole 23 is arranged in the center of the limiting flange 2; the locking device used is a locking screw 4.
In this embodiment, the motor shaft that is connected with rotor 1 is the internal thread type, when installing rotor 1 on the motor shaft, at first arrange rotor 1 in on the motor shaft, because the motor shaft is the internal thread type, so the top of motor shaft is located mounting hole 11, then arrange limiting flange 2 in rotor 1's mounting groove, it is fixed with limiting flange 2 and rotor 1 to use bolt 5, pass limiting flange 2's through-hole 23 with locking screw 4 lower extreme at last and stretch into rotor 1's mounting hole 11 in, and with the internal thread screw-thread fit of motor shaft, screw up locking screw 4, wholly be fixed in on the motor shaft with limiting flange 2 and rotor 1. In this embodiment, if the limiting flange 2 is not arranged in the mounting groove of the rotor 1, it is obvious that even if the locking screw 4 is screwed, the rotor 1 and the internal thread type motor shaft cannot be fixed, so that the centrifuge rotor 1 cannot work normally; therefore, the limiting flange 2 and the locking screw rod 4 are arranged in the mounting groove of the rotor 1, the limiting flange 2 and the rotor 1 are integrally connected with the motor shaft downwards through screwing the locking screw rod 4, the rotor 1 and the inner thread type motor shaft can be fixed, and the centrifuge rotor 1 can be driven by the motor shaft to perform centrifugal work.
When the rotor 1 in embodiment 1 is mounted on the motor in embodiment 2, only the limiting flange 2 and the locking device need to be replaced, and the locking device refers to replacement between the locking nut 3 and the locking screw rod 4, so that the fixed connection of the centrifuge rotor 1 on different motor shafts can be realized.
