Description

Technical Field

[0001] The utility model relates to the technical field of thermal conductivity measuring instruments, in particular to a thermal conductivity measuring instrument with a protection mechanism. Background Art

[0002] Thermal conductivity meter is one of the main thermal properties of insulation materials and is the main indicator for identifying the quality of insulation performance of materials. Insulation materials are widely used in construction, among which direct buried insulation pipes need to be tested for thermal conductivity after production.

[0003] Some devices on the market generally drive the forward and reverse motors to drive the threaded rods to rotate, so that the U-shaped frame drives the moving plate to move. When the moving plate moves downward, the slider and the slide groove can drive the pushing plate to approach each other on the moving hole, thereby completing the fixed clamping of the building insulation board, avoiding the building insulation board being fixed inside the measuring instrument, and the building insulation board being tilted, resulting in deviations in the detected data.

[0004] However, in actual use of the above equipment, when the clamping plate clamps the direct-buried insulated pipe, the curved outer surface of the direct-buried insulated pipe requires the clamping plate to use too much force, which will cause damage to the outer surface of the direct-buried insulated pipe. In view of this, we propose a thermal conductivity coefficient measuring instrument with a protective mechanism. Utility Model Content

[0005] The purpose of the utility model is to provide a thermal conductivity tester with a protection mechanism to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a thermal conductivity tester with a protective mechanism, comprising a box, a detection assembly is arranged on one side of the inner wall of the box, a hydraulic telescopic rod is arranged on the top of the box, a mounting groove is opened at the bottom of the inner wall of the box, a spring is fixedly connected to the bottom of the inner wall of the mounting groove, one end of the spring is fixedly connected to a mounting seat, a clamping structure is arranged inside the mounting seat, and the clamping structure includes:

[0007] An electric telescopic rod, wherein the bottom of the inner wall of the mounting seat is fixedly connected to the electric telescopic rod, the top of the electric telescopic rod is fixedly connected to a mounting block, and one side of the mounting block is hinged with a connecting rod;

[0008] A connecting piece is hinged on the inner wall of the mounting seat, an inclined surface is arranged at the bottom of the connecting piece, a clamping block is fixedly connected to the top of the connecting piece, and the clamping block is arranged in the form of a special-shaped block.

[0009] Preferably, the electric telescopic rod is arranged at the bottom center of the inner wall of the mounting seat, and a mounting block is arranged at the top center of the electric telescopic rod, which can enable the mounting block to be well installed inside the mounting seat.

[0010] Preferably, the hinge between the connecting member and the mounting seat is close to the bottom of the connecting member, and the size of the connecting member is matched with the size of the inside of the mounting seat, which allows the connecting member to move well inside the mounting seat.

[0011] Preferably, one end of the connecting rod is hinged to one side of the connecting piece near the top, and the length of the connecting rod is matched with the distance between the mounting block and the connecting piece, which can enable the connecting rod to move better.

[0012] Preferably, a threaded rod is rotatably connected to a top corner of an outer surface of the mounting seat, and a clamping piece is threadedly connected to an outer surface of the threaded rod.

[0013] Preferably, the clamping member is arranged in a C-shape, and one side of the clamping member close to the center of the mounting seat is arranged in an arc shape.

[0014] Compared with the prior art, the utility model provides a thermal conductivity tester with a protection mechanism, which has the following beneficial effects:

[0015] 1. In order to prevent the equipment from being damaged when clamping the direct-buried insulated pipe, the thermal conductivity tester with a protective mechanism places the direct-buried insulated pipe on the upper surface of the mounting seat, and the electric telescopic rod is extended to move the end of the connecting rod hinged to the mounting block upward, which makes the other end of the connecting rod push one side of the connecting piece close to the top, so that the clamping block contacts the inner wall of the direct-buried insulated pipe, and the clamping block is arranged as a special-shaped block, and the side of the clamping block away from the mounting block is arranged in an arc shape, and the arc surface is provided with a rubber anti-skid layer, so that the clamping block can clamp the inside of the direct-buried insulated pipe well, and when clamping a smaller direct-buried insulated pipe, the direct-buried insulated pipe is placed in the center of the mounting seat, and then the electric telescopic rod is contracted, so that the connecting rod pulls the connecting piece, so that the clamping block clamps the outer surface of the direct-buried insulated pipe, so that the direct-buried insulated pipe can be clamped more stably and not easily damaged.

[0016] 2. In order to make the direct-buried insulated pipe more stable during testing, the thermal conductivity tester with a protective mechanism rotates the threaded rod to move the clamping piece toward the direct-buried insulated pipe when clamping a larger direct-buried insulated pipe. This makes the arc surface of the clamping piece contact the outer surface of the larger direct-buried insulated pipe, thereby making the direct-buried insulated pipe more stable while supporting the insulation device.
