Description

Strain gauge fixing clamp

Technical Field

The utility model relates to a stress strain signal acquisition technical field especially relates to a foil gage fixation clamp.

Background

When mechanical equipment stress strain detection is carried out, a stress strain signal of the equipment needs to be acquired through a strain gauge, and welding is often adopted for connection of the strain gauge and an electric wire. A plurality of measuring points are arranged in one detection experiment, a plurality of strain gauges are required to be welded each time, and a large amount of time is consumed. In addition, due to improper operation in the welding process and damage of the strain gauge in the detection process, the workload of strain gauge welding is increased, financial resources and material resources are wasted, and the strain gauge is not paid back. Meanwhile, due to the operability of welding, poor connection between the strain gauge and the wire may be caused, so that acquisition of a stress-strain signal fails. Finally, only the joint of the strain gauge and the electric wire is subjected to welding treatment, and two poles of the strain gauge are still exposed in the air, so that due to the environmental influence, if the two poles are in contact with mechanical equipment, the acquisition effect is invalid, and the acquisition process fails.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a foil gage fixation clamp to the technical defect who exists among the prior art.

For realizing the utility model discloses a technical scheme that the purpose adopted is:

the utility model provides a foil gage fixation clamp, includes a fixation clamp body, two fixation clamp caps, and two fixation clamp caps have the external screw thread, the fixation clamp body has two screw thread blind holes of arranging side by side of cooperation external screw thread, every the screw thread blind hole respectively with a pair of through-hole on the fixation clamp body communicates with each other, and this axis line to the through-hole is perpendicular with the axis of screw thread blind hole, and two through-holes that are located the homonymy are installed insulating isolation tube and are outwards stretched out one section distance for with the two poles of the earth isolation of male foil gage, be located two through-holes of opposite side, be used for the insertion of the line of the two poles of the earth of foil gage, the fixation clamp cap is used for compressing tightly the two poles of the earth of the.

Detailed Description

The present invention will be described in further detail with reference to the following drawings and specific embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

As shown in fig. 1-6, the strain gage fixing clip of the present invention comprises a fixing clip body 3, two fixing clip caps including a first fixing clip cap 1 and a second fixing clip cap 2, the two fixing clip caps having external threads 5, the fixed clamp body is provided with two thread blind holes 9 which are matched with the external thread and are arranged in parallel, each thread blind hole is respectively communicated with a pair of through holes on the fixed clamp body, and the axis line of the pair of through holes is vertical to the axis of the threaded blind hole, two through holes positioned at the same side are provided with insulating isolation pipes (comprising a first insulating isolation pipe 4 and a second insulating isolation pipe 8) and extend outwards for a certain distance, the fixing clamp cap is used for isolating two poles 11 of an inserted strain gauge 10, two through holes positioned on the other side comprise a first through hole 6, a second through hole 7 is used for inserting a connecting line 12 of the two poles of the strain gauge, and the fixing clamp cap is used for pressing the two poles of the strain gauge and the connecting line thereof to the bottom of the threaded blind hole to realize connection.

The bottom surface of the threaded blind hole is a plane.

The through hole is a round hole, the insulating isolation pipe is a round pipe, preferably, the insulating isolation pipe is a plastic pipe and is bonded with the connected through hole, and other materials can be adopted. The retaining clip is formed of a conductive metal material, such as copper.

In the present invention, the through hole may be a circular hole, or may be other holes, and the present invention is not limited thereto, and the insulating isolation tube may be other non-circular tubes, specifically, not limited thereto.

During the specific application, the first through-hole 6 of connecting wire, the input of second through-hole 7, the input of first insulation spacer 4, the insulating spacer 8 of second respectively of foil gage both ends, because the material of first insulation spacer 4, the insulating spacer 8 of second is plastics, can keep apart the foil gage both poles, avoid contacting, also avoided simultaneously with the problem that measures the part and contact. And after the steps are completed, screwing and clamping the fixing clamp cap from the upper end of the fixing clamp body to complete connection.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of improvements and decorations can be made without departing from the principle of the present invention, and these improvements and decorations should also be regarded as the protection scope of the present invention.
