Description

Nonmagnetic mounting bracket

Technical Field

The utility model belongs to the technical field of the sclausura installation technique and specifically relates to a nonmagnetic waveguide installing support for electron paramagnetic resonance spectrometer.

Background

An electron paramagnetic resonance spectrometer is an instrument used for qualitatively and quantitatively detecting unpaired electrons contained in substance atoms or molecules and exploring the structural characteristics of the surrounding environment. The electron paramagnetic resonance spectrometer mainly comprises two annular electromagnets which are oppositely arranged, an electron paramagnetic resonance probe which is arranged between the two electromagnets and a waveguide tube which is connected with the electron paramagnetic resonance probe, wherein microwave signals enter the waveguide tube through a coaxial waveguide conversion structure.

Because the electromagnet is not provided with a mounting hole, the electron paramagnetic resonance probe in the prior art is generally fixed in a suspension mode, specifically, a fixed rod extends out of a bracket for mounting the electromagnet, and the electron paramagnetic resonance probe is fixed at the end part of the fixed rod; one end of the waveguide tube is connected with the electron paramagnetic resonance probe, and the other end of the waveguide tube is fixed on a bracket for mounting the electromagnet. The mounting and fixing mode has the following defects: 1. the structure is complex, and a fixed rod and an adjusting component thereof need to be additionally arranged; 2. the adjustment of the relative position and angle between the electron paramagnetic resonance probe and the waveguide between the two electromagnets is realized by adjusting the fixed rod, belongs to indirect adjustment, and has certain inconvenience; 3. the waveguide tube is only fixed at two ends, and the middle section is in an unsupported state, so that the stability is poor.

SUMMERY OF THE UTILITY MODEL

To the above problem, the utility model provides a nonmagnetic waveguide installing support for electron paramagnetic resonance spectrometer.

A nonmagnetic mounting bracket comprises a U-shaped hoop cavity with an open front side, inner jacking screws screwed into the U-shaped hoop cavity from the left side and the right side, and outer jacking bolts fixed on the left side and the right side of the U-shaped hoop cavity; the inner tightening screw is used for fixing the waveguide tube inwards, and the outer tightening bolt is used for tightening the inner side faces of the annular electromagnets at the two sides outwards.

Furthermore, the clamping pieces are arranged on the left inner side wall and the right inner side wall of the U-shaped hoop cavity, the clamping pieces are connected to the inner jacking screws, and the inner jacking screws are used for fixing the waveguide tube inwards through extruding the clamping pieces.

Furthermore, a first rubber pad is fixed on one side of the clamping piece, which is in contact with the waveguide tube.

Furthermore, the outer jacking bolt consists of a screw fixedly connected to the U-shaped hoop cavity and an adjusting bolt sleeved on the screw.

Furthermore, a second rubber pad is arranged on one side, in contact with the annular electromagnet, of the adjusting bolt.

The utility model has the advantages that: 1. the waveguide tube is fixed without drilling or welding external devices, so that the waveguide tube is convenient to mount and dismount, attractive in appearance and high in stability; 2. the waveguide tube fixing device is suitable for installation of waveguide tubes with different shapes and calibers and has strong adaptability.

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

A nonmagnetic mounting bracket is shown in figures 1 and 2 and comprises a U-shaped hoop cavity 1 with an open front side, inner tightening screws 2 screwed into the U-shaped hoop cavity from the left side and the right side, and outer tightening bolts 3 fixed on the left side and the right side of the U-shaped hoop cavity; the inner tightening screw 2 is used for fixing the waveguide tube inwards, and the outer tightening bolt 3 is used for tightening the inner side faces of the annular electromagnets at the two sides outwards.

For the increase with the contact surface of waveguide pipe, improve installation stability, U type staple bolt cavity left and right inside wall all is equipped with clamping piece 4, clamping piece 4 connect in on the tight screw 2 of interior top, interior top tight screw 2 is through 4 internal fixation waveguide pipes of extrusion clamping piece, passes through again clamping piece 4 sets up first rubber pad 5, reinforcing and the frictional force of waveguide pipe with waveguide pipe contact one side. The clamping piece has a larger contact surface with the waveguide tube as much as possible, so that the clamping force of the clamping piece on the waveguide tube is equal, and the waveguide tube cannot deform due to local stress. The inner tightening screw 2 can be a knurled screw convenient for screwing by hand.

In order to facilitate the adjustment of the outer tightening bolt, the outer tightening bolt 3 consists of a screw rod 6 fixedly connected to the U-shaped hoop cavity and an adjusting bolt 7 sleeved on the screw rod. And a second rubber pad 8 is arranged on one side of the adjusting bolt 7, which is in contact with the annular electromagnet, and is used for enhancing the friction force with the annular electromagnet.

And cover plates 9 are arranged on the top surface and the bottom surface of the U-shaped hoop cavity.

Through the utility model provides a nonmagnetic installing support carries out fixed schematic structure of wave guide as shown in figure 3, figure 4. For waveguides with different shapes, the waveguide can be matched by adjusting the shape of the clamping piece; the waveguide tubes with different calibers and different distances between the annular electromagnets can be adjusted by matching with the rotating inner tightening screw and the outer tightening screw, and both can achieve good installation effect.

The utility model provides a waveguide pipe installing support does not need drilling or welding peripheral hardware to fix the waveguide pipe, easy to assemble, dismantles and adjusts, and the appearance is pleasing to the eye, and stability is high. In order to avoid interference, the whole mounting bracket is made of nonmagnetic materials.

The utility model discloses except being used for the fixed mounting of electron paramagnetic resonance spectrometer waveguide, still can continue to use under to similar installation scene.
