Detailed Description

The present utility model will be described in further detail with reference to the accompanying drawings.

The utility model provides a grab ware is changed to separator filter core of this application that reference fig. 1 through 6 show mainly includes extension rod 1 to and set firmly in mount pad 2 of this extension rod 1 one end, have the tongs 3 that at least three activity set up on the mount pad 2, tongs 3 are annular array and distribute, and the one end that the tongs 3 kept away from mount pad 2 has the first 30 of tongs, and the inboard of first 30 orientation tongs 3 of tongs is convenient for operate generally, and tongs 3 are three, and three tongs 3 are equilateral triangle generally and distribute.

In this application, in order to make the grab ware adapt to the filter core of more size specifications, so tongs 3 set up on mount pad 2 with rotatable mode, to the mounting structure of tongs 3 simultaneously, mainly given two kinds of implementation modes:

the first gripper 3 can rotate around the axis of the extension rod 1, that is, the gripper 3 rotates in the horizontal direction, as shown in the figure, the mounting seat 2 mainly comprises an upper clamping plate 2a and a lower clamping plate 2b which are arranged in a vertically opposite mode, a central gear 20 which is arranged in a rotatable mode and driven gears 21 which are uniformly distributed along the circumferential direction of the central gear 20 are arranged between the upper clamping plate and the lower clamping plate through bearings, the driven gears 21 are meshed with the central gear 20, the grippers 3 are in one-to-one correspondence with the driven gears 21 and are fixedly connected, the central gear 20 is connected with an operating rod 4, the operating rod 4 is arranged in parallel with the extension rod 1, the extending direction is consistent with the extension rod 1, the upper end of the gripper 3 is connected with the circumferential outer side of the driven gear 21, and thus when the central gear 20 drives the driven gears 21 to rotate, the grippers 3 can be driven to be close to or far away from the mounting seat 2, and the sizes which can be gripped are changed.

In this embodiment, the extension rod 1 is of a sleeve structure, the control rod 4 is coaxially arranged with the extension rod 1 and penetrates out of the extension rod 1, the length of the extension rod is longer than that of the extension rod 1, the distal end of the control rod 4 is provided with a cross rod 40 arranged along the radial direction of the extension rod, and the cross rod 40 and the control rod 4 can be connected in a clamping, welding or threaded mode.

According to the second embodiment, the gripper 3 can vertically rotate around the radial section of the extension rod 1, a torsion spring is arranged between the upper end of the gripper 3 and the mounting seat 2, the torsion spring applies inward rotation force to the gripper 3, in this embodiment, the upper portion of the gripper 3 is linear, the upper end of the gripper is arranged on the mounting seat 2 through a horizontal shaft arranged horizontally, so that the gripper can rotate on a numerical plane, one end of the torsion spring is fixed on the horizontal shaft, the other end of the torsion spring acts on the gripper 3, the lower ends of all grippers 3 are in inward rotation trend, namely, the lower ends are close to the central axis of the mounting seat 2, and when the structure is used, personnel are initially required to outwards open the gripper 3 and then extend the gripper into the separator.

In this application, in order to prevent the situation that the position of the gripper 3 is changed to cause that the gripper cannot be pulled out smoothly in the pulling-out process, the lever 4 is further provided with a locking ring 5, and the locking ring 5 is used for locking the lever 4 and the extension rod 1 with each other.

As regards the structure of the locking ring 5, two embodiments are also proposed in this example, the first locking ring 5 being in threaded engagement with the lever 4 and having an outer diameter greater than the inner diameter of the extension rod 1, the extension rod 1 being locked against the lever 4 when the end of the locking ring 5 abuts against the extension rod 1.
