Detailed Description

The utility model provides a simply pull out a ware, should pull out a ware both can dismantle axle type part rapidly in the regional use that does not have energy such as electric energy, compressed air, can guarantee the integrality of axle type part again furthest, has solved the problem that exists well among the background art.

Referring to fig. 1, the present invention mainly comprises a T-shaped rod 1, a power block 2, a beam 3, a locknut 4, a pull rod 5, a knuckle bearing 7, a fixing nut 8 and a movable self-locking device 6, wherein the movable self-locking device 6 comprises a locking bolt 10, a locking nut 11, an inverted bur 13 and a C-shaped hoop 14.

The power block 2 is sleeved on the T-shaped rod 1 and can freely slide on the T-shaped rod 1.

The T-shaped rod 1 is installed on the cross beam 3 through threads and penetrates through the cross beam 3; the locknut 4 is arranged on the T-shaped rod 1 penetrating through the cross beam 3, so that the connection strength of the T-shaped rod 1 and the cross beam 3 is enhanced, and the connection impact resistance is enhanced.

The tie rod 5 is connected to the cross beam 3 by means of a T-shaped groove, the other end of which passes through a knuckle bearing 7 and is fixed by means of a fixing nut 8, the function of which is to constitute an impact-resistant frame.

The inner ring of the joint bearing 7 is arranged on the pull rod 5, and the outer ring is arranged in the ear seat 12 of the C-shaped hoop 14, so that the joint bearing plays a role in connecting the pull rod 5 and the movable self-locking device 6, and simultaneously, the pull rod 5 can freely rotate in a certain range relative to the movable self-locking device 6.

Referring to fig. 2, a trunnion 12 is respectively arranged at both sides of the c-shaped hoop 14 and used for mounting the joint bearing 7; a circle of inverted spurs 13 are arranged on the inner side of the C-shaped hoop 14 and used for fixing the shaft parts 9; and the locking nut 10 and the locking bolt 11 are arranged at the end part of the C-shaped hoop 14 and are used for contracting the C-shaped hoop 14 to ensure that the inverted bur 13 is tightly contacted with the shaft part 9, so that the movable self-locking device 6 and the shaft part 9 are fixed.

Referring to fig. 3 and 4, the inverted-U-shaped spine 13 has a one-way self-locking function, and the included angle between the end surface of the free end and the axial direction of the inverted-U-shaped spine is 45 degrees, so that the degree of wedging with the shaft parts is increased.

During the use, the axle head suit of axle type part 9 that will pull out is in the inside of C type hoop 14 to extrude the structure shown in fig. 3, again with locking bolt 10 and lock nut 11 screw up, shrink C type hoop 14, make the laminating of falling spurs 13 and axle type part 9 inseparabler, make full use of falls spurs 13 characteristic and carries out one-way auto-lock, later relies on the inertia impact force that power block 2 slides the production, pulls out axle type part 9.

The beneficial effects of the utility model are that: the connection is firm, and impact resistance is strong, does not need the external energy source, can use under any environment.
