Description

A kind of dismounting top gripper to wheel

The utility model relates to a kind of dismounting hand tools, is specially a kind of dismounting top gripper to wheel.

In present mechanical part connected, some was used wheel is connected, and was for example used between motor rotation axis and the quilt device that drives to be connected taking turns.With the parts that wheel is connected, service time is of a specified duration, and because of to wheel and other parts corrosion together, dismounting is very difficult, often will it be cut off with cutting mode, will cause the damage to parts like this when dismounting.To so far, a kind of extracting tool that will be easy to disassemble to wheel is not arranged also.

The purpose of this utility model provides a kind of dismounting top gripper to wheel, and this dismounting top gripper can be easy to corrosion wheel is disassembled, and need not cause the damage to parts again with cutting.

To achieve these goals, the utility model is to have on the tube top of connection support member cylindraceous that opening, lower end are opening in its front and back end to have in the center hole of internal thread, be equipped with have screw thread on it, screw rod that the bottom has annular groove, the bottom of screw rod is the fixed cover of the cover tubular of opening by its lower end that is threaded, and in the fixed cover and the bottom of screw rod is equipped with clamping element.

Utilize the utility model, can disassemble at an easy rate wheel, need not cut, parts are damaged, so it is that dismounting connects the ideal tools to wheel using of a specified duration to dismantle the connection of not getting off because of corrosion.Dismantle nut on the fastening bolt that do not get off because of corrosion on the also detachable simultaneously mechanical device, can also dismantle the coded lock that can't open because of key loss on the safety cabinet.

Below in conjunction with accompanying drawing the utility model is explained

Fig. 1: front view of the present utility model

Fig. 2: side view of the present utility model

Fig. 3: A-A is to cutaway view among Fig. 1

Fig. 4: B-B is to cutaway view among Fig. 2

The utility model is that its front and back end has opening, the lower end is the connection support member 1 cylindraceous of opening, the tube that connects support member 1 pushes up and is equipped with the center hole that has internal thread, be equipped with a rotating screw bolt 2 that has screw thread on it in the center hole, be equipped with a hand lever 3 in the circular hole that the upper end of rotating screw bolt 2 has, the bottom of rotating screw bolt 2 has annular groove, the bottom of rotating screw bolt 2 is the fixed cover 4 of the cover tubular of opening by its lower end that is threaded, and is equipped with the clamping element 7 that has center hole on its that a chuck by two semicircle tubulars of mutual symmetry constitutes in the fixed cover 4 and in the annular groove of rotating screw bolt 2.

On the connection flange of the bottom that connects support member 1, be connected with the base for supporting 6 that has the connection boss on it by bolt fastener 5.

When using the utility model, rotate hand lever 3 earlier, make rotating screw bolt 2 be pivotally lowered into the bottom that connects support member 1, clamping element 7 is clipped in the connection that to dismantle on the wheel, clamping element 7 is placed again in the fixed cover 4 that is connected with rotating screw bolt 2 then, rotate hand lever 3 then, make it rotating screw bolt 2 and upwards rotate, make it connection at last wheel is disassembled from connecting axle.

Claims

One kind to the wheel dismounting top gripper, it is characterized in that: have opening its front and back end, the lower end is to have in the center hole of internal thread on the tube top of connection support member cylindraceous (1) of opening, be equipped with the rotating screw bolt (2) that has screw thread on it, be equipped with bar (3) on the other hand in the circular hole that the upper end of rotating screw bolt (2) has, the bottom of rotating screw bolt (2) has annular groove, in the bottom of rotating screw bolt (2) is the fixed cover (4) of the cover tubular of opening by its lower end that is threaded, and is equipped with the clamping element (7) that has center hole on its that a chuck by two semicircle tubulars of mutual symmetry constitutes in the fixed cover (4) and in the annular groove of rotating screw bolt (2).
2. a kind of dismounting top gripper to wheel according to claim 1 is characterized in that: on the connection flange of the bottom that connects support member (1), be connected with the base for supporting (6) that has the connection boss on it by bolt fastener (5).
