[0024] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0025] like Figure 1-8 As shown, a device for accurately positioning a prestressed corrugated pipe comprises a bracket 1, characterized in that: a clamping mechanism 2 is provided on the top of the bracket 1, the clamping mechanism 2 comprises a clamping jaw 3, both sides of the clamping jaw 3 are rotatably connected to a clamping jaw 2 4, both sides of the clamping jaw 2 4 are rotatably connected to the bracket 1, one side of the clamping jaw 2 4 is fixedly connected to a ratchet 5, the other side of the clamping jaw 2 4 is fixedly connected to a worm gear 6, one side of the worm gear 6 is meshingly connected to a worm 7, both ends of the worm 7 are rotatably connected to the bracket 1, one side of the clamping jaw 3 is fixedly connected to the top of a support shaft 8 and is rotatably connected to a hook claw 9, the outer side of the support shaft 8 is movably connected to a torsion spring 10, and one end of the torsion spring 10 is movably connected to the hook claw 9.

[0026] In this embodiment, both ends of the bracket 1 are fixedly connected to two limit blocks 11, the front of the limit blocks 11 are rotatably connected to two clamping rings 12, the front of the two clamping rings 12 are fixedly connected to a fixing block 13, one of the two fixing blocks 13 has an inner rotation connection knob 14, and the other of the two fixing blocks 13 has an inner meshing connection knob 14.

[0027] The clamping ring 12 can be provided to clamp the steel bar, thereby fixing the bracket 1 .

[0028] In this embodiment, the outer shape of the clamping ring 12 is arc-shaped, and circular protrusions are provided at the top and the bottom of the rear end of the clamping ring 12 .

[0029] The clamping ring 12 can rotate inside the limiting block 11 to clamp steel bars of different diameters.

[0030] In this embodiment, one end of the support shaft 8 is grooved, and the inner side of the hook claw 9 is grooved.

[0031] The two ends of the torsion spring 10 are respectively connected to the grooves of the support shaft 8 and the hook 9, so that the hook 9 maintains contact with the ratchet 5.

[0032] In this embodiment, round holes are formed on both sides of the bracket 1 , and two small round holes are formed on the top of one side of the bracket 1 .

[0033] The space 1 is connected to the worm 7 through two small circular holes, and the angle of the pipeline can be adjusted by rotating the worm 7.

[0034] In this embodiment, circular protrusions are provided on both sides of the second clamping jaw 4, and circular holes are opened on both sides of the first clamping jaw 3.

[0035] The second clamping jaw 4 is connected to the first clamping jaw 3 via a circular protrusion, so that the first clamping jaw 3 and the second clamping jaw 4 can rotate relative to each other with the connection as the center.

[0036] In this embodiment, the outer shapes of the clamping jaw 1 3 and the clamping jaw 2 4 are both rectangular rings, and arc-shaped depressions are formed at both ends of the clamping jaw 1 3 and the clamping jaw 2 4 .

[0037] There is a certain opening and closing angle between the clamping jaw 1 3 and the clamping jaw 2 4, so that corrugated pipes of different diameters can be clamped.

[0038] It should be noted that the utility model is a device for accurately positioning a prestressed corrugated pipe, which has the function of being easy to install when in use. The specific implementation method is to rotate the knob 14 to remove it from the fixing block 13 with the screw hole, so that the two clamping rings 12 can be opened in different directions, and then the middle of the two clamping rings 12 is aligned with the steel bar, and then the two clamping rings 12 are brought close to each other to clamp the steel bar, and then the knob 14 is rotated in the opposite direction to connect the two clamping rings 12 through the knob 14, so that the clamping ring 12 clamps the steel bar, and in the same way, the other three groups of clamping rings 12 are clamped in turn to fix the bracket 1;

[0039] After fixing the bracket 1, move the hook claw 9 to release its connection with the ratchet 5, thereby releasing the constraint on the ratchet 5, and then pull the clamping claw 1 3 and the clamping claw 2 4 in the opposite direction, so that the clamping claw 1 3 and the clamping claw 2 4 are centered on the connection, and rotate and open in the opposite direction, and then release the hook claw 9, so that it can restore the connection with the ratchet 5 under the action of the torsion spring 10, and the bellows is passed through the gap opened by the clamping claw 1 3 and the clamping claw 2 4 in turn, and then close the clamping claw 1 3 and the clamping claw 2 4. After the clamping claw 1 3 and the clamping claw 2 4 move a certain distance, they will contact the outer wall of the bellows and clamp it. The clamping claw 2 4 will drive the ratchet 5 to rotate together while rotating. The ratchet 5 can only rotate in one direction due to the restriction of the hook claw 9, so that the clamping claw 1 3 and the clamping claw 2 4 will not retreat and loosen after clamping the bellows;

[0040] Since the bellows usually needs to be installed in a certain curved state, the inclination amplitude of the two ends of the bellows can be adjusted by the worm 7. The specific implementation method is to rotate the worm 7, and the worm 7 drives the worm wheel 6 to rotate while the worm wheel 6 rotates. When the worm wheel 6 rotates, it will drive the clamping jaw 2 4 connected thereto to rotate. After the clamping jaw 1 3 and the clamping jaw 2 4 clamp the bellows, the clamping jaw 1 3 is constrained by the ratchet 5 and the bellows, and the two rotation directions are fixed. Therefore, it will rotate together with the clamping jaw 2 4. The rotation of the clamping jaw 1 3 and the clamping jaw 2 4 will drive the bellows to rotate together. By rotating the worm 7 in different directions, the inclination angle of the bellows can be adjusted;

[0041] By providing the clamping mechanism 2, the positioning device can be installed more quickly, saving the time required for installation, improving work efficiency, and facilitating adjustment of the inclination angle of the bellows, so that the staff can make adjustments according to needs, thereby increasing the adaptability of the positioning device.

[0042] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
