Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention have been presented for purposes of illustration and description, and are not intended to be exhaustive or limited to the invention in the form disclosed. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiment was chosen and described in order to best explain the principles of the invention and the practical application, and to enable others of ordinary skill in the art to understand the invention for various embodiments with various modifications as are suited to the particular use contemplated.

Example 1

The utility model provides a fixed regulation buckle, as shown in fig. 1, fig. 2, includes clamp 1 and regulating part 2, regulating part 2 by spacing in the inside regulation pole 201 of clamp with be fixed in the regulating rod tip is stretched out the screw thread post 202 of clamp constitutes, clamp 1 corresponds to be provided with logical groove 3 on the position of adjusting the pole, be used for rotating thereby adjust pole 201 and drive screw thread post 202 rotates. In practical use, the threaded column 202 is in threaded connection with the structure to be fixed, specifically, a threaded hole matched with the threaded column is formed in the structure to be fixed, and the threaded column can be screwed in and out in the threaded hole. The clamp is used for relatively fixing whole buckle, and the screw post is relatively fixed promptly to screw in through the screw post is screwed out and can be made to wait that fixed knot structure takes place a little displacement change or shape change, and then realizes the straight line fine setting of position.

The adjusting rod can be a conventional cylindrical polished rod, but is preferably of a hexagonal prism structure, and the rotating operation can be carried out more easily by an external hexagonal wrench. The adjusting rod and the threaded column can be of an integral structure.

The limiting structure of the adjusting rod can be realized by adopting a conventional technical means, for example, two sides of the adjusting rod can be respectively embedded into the side walls of two sides of the through groove, and a space allowance for the rotation of the adjusting rod is reserved, as shown in fig. 3; of course, other limiting structures which can limit the adjusting rod and do not hinder the adjusting rod from rotating relative to the hoop can be used, and the limiting structure is not limited in the embodiment. In addition, figure 3 has still given an adjustment piece mounting structure, adjusts pole 201 and corresponds from the clamp and treat that fixed knot constructs one side and penetrate, and the back of targetting in place is installed, fixes limiting plate 4 and clamp through countersunk screw again to prevent to adjust pole 201 and deviate from the clamp, the screw thread post diameter is less than adjusts pole diameter or its circumscribed circle diameter, and the screw thread post is worn out from the limiting plate.

Example 2

Different from embodiment 1, as shown in fig. 4 and 5, the adjusting rod 201 of this embodiment is fixedly sleeved with an embossing knob 203 for rotation. For ease of installation, the clip is formed from a clip body 101 and a mating member 102 removably secured to the clip body.

The adjusting rod 201 is limited and fixed between the clamp body 101 and the matching piece 102, and an opening 103 for accommodating the embossing knob 203 is formed in one side, close to the clamp body, of the matching piece 102. The limiting structure in this embodiment may be similar to embodiment 1, where the embossing knob 203 is narrower than the adjusting rod 201, and two ends of the adjusting rod 201 are respectively embedded into the band body 101 and the engaging piece 102.

The clamp body 101 and the matching piece 102 are embedded into the notch of the adjusting rod, and a gasket 104 is padded inside the notch of the adjusting rod, and the gasket can be made of polyformaldehyde materials and plays a role in lubricating and preventing loosening of the adjusting piece. The clip body 101 and the mating member 102 are detachably and fixedly connected by a screw 105.

The working principle of the embodiment is the same as that of the embodiment 1, and the difference is that the adjusting rod 201 can be rotated only through the embossing knob 203, so that the operation is more convenient and quicker. Here, the adjustment piece and the embossing knob can be directly replaced by a modified knob screw, in that a boss is provided on the back of the existing knob screw for embedding into the clamp body.
