Wherein, the diameter of the circumcircle of the nut is greater than the width of the long groove.

Wherein, the other side wall of the V-shaped positioning block is provided with a plurality of long grooves in parallel and at intervals along the width direction.

Wherein, the side wall of the V-shaped positioning block is hinged with multiple pressing rods in parallel and spaced along the width direction.

Wherein, the plurality of pressing rods are provided in one-to-one correspondence with the plurality of long slots.

Beneficial effects of the utility model: the utility model provides a round tube fixing device, which includes a V-shaped positioning block, a round tube arranged in the V-shaped groove of the V-shaped positioning block, and the V-shaped positioning block. One end of the side wall is hinged to be used to press the pressure rod of the circular tube, and the pressure rod is fastened to the other side wall of the V-shaped positioning block away from the hinged position; the other side of the V-shaped positioning block The outer side wall of the wall is arranged in a spherical shape, and the other side wall of the V-shaped positioning block is provided with a long groove along the length direction, and the end of the pressure rod away from the hinge position is provided with an external thread. One end away from the hinged position is arranged in the long groove and fastened to the other side wall of the V-shaped positioning block by a nut. The round tube fixing device designed with this structure can conveniently and quickly clamp and position round tubes with different outer diameters through the flexible connection between the pressure rod and the side wall of the V-shaped positioning block, and then effectively improve the stability of the round tube fixing device. Versatility.

Description of drawings

Fig. 1 is a structural schematic diagram of a round pipe fixing device of the present invention.

Detailed ways

The technical solutions of the present utility model will be further described below with reference to the accompanying drawings and through specific embodiments.

As shown in FIG. 1 , this embodiment provides a round tube fixing device, including a V-shaped positioning block 1, a round tube 2 arranged in the V-shaped groove of the V-shaped positioning block 1, and the V-shaped positioning block. One end of the side wall of the positioning block 1 is hinged to be used to press the pressure rod 3 of the circular tube 2, and the pressure rod 3 is fastened to the other side wall of the V-shaped positioning block 1 away from the hinged position; the V The outer side wall of the other side wall of the V-shaped positioning block 1 is spherically arranged, and the other side wall of the V-shaped positioning block 1 is provided with a long groove (not marked in the figure) along the length direction. 3. The end away from the hinge position is provided with an external thread, and the end of the pressure rod 3 away from the hinge position is set in the long groove and fastened to the other side wall of the V-shaped positioning block 1 by a nut.

Specifically, in order to make it easier for the nut to closely fit the outer wall of the V-shaped positioning block 1 when locking the pressure rod, and to increase the stability and reliability of the round tube fixing device when locking, in this embodiment, the nut The lower end surface of the nut 221 is arranged in a spherical shape, and the lower end surface of the nut 221 is in close contact with the spherical surface of the outer side wall of the other side wall of the V-shaped positioning block 1 . In addition, the diameter of the circumcircle of the nut 21 in this embodiment is larger than the width of the long groove.

In this embodiment, in order to improve the stability of the clamping of the round pipe when fixing the longer round pipe, the other side wall of the V-shaped positioning block 1 is provided with a plurality of long grooves in parallel and at intervals along the width direction. A side wall of the V-shaped positioning block 1 is hinged with a plurality of pressing rods 3 in parallel and at intervals along the width direction, and the plurality of pressing rods 3 are arranged correspondingly to the plurality of long grooves. This structural design can not only effectively meet the clamping of round tubes with different outer diameters, but also effectively improve the stability and reliability of round tube clamping.
