Description
Technical Field
The utility model relates to the technical field of experimental equipment, in particular to a measuring device for thermal extension.
Background
Thermal elongation is the elongation (under tension) of the plastic after heating, and is primarily considered to be the degree of crosslinking of the polyethylene of the crosslinked cable, with higher degrees of crosslinking leading to less thermal elongation.
The thermal extension test is an important index for testing the mechanical physical properties of the cable insulation layer, the rationality of a test instrument directly influences the test result and efficiency, a load part is added to the cable in the test process, the load part randomly drops at the moment of removing the load part, large force is generated due to gravity when the load part drops, accidents easily occur to hurt passers-by, and the existing measuring device is not provided with a structure aiming at the shock absorption and bearing effects of the drop of the load part; when the length of the cable is read, the cable is placed at a position far from the ruler, and therefore, errors are likely to occur when data is read.
SUMMERY OF THE UTILITY MODEL
The technical problems to be solved by the utility model are as follows: provided is a measuring device which has a buffering effect on a load member and can read measurement data intuitively.
In order to achieve the purpose, the utility model provides a measuring device for thermal extension, which comprises two support tables, two supports, two clamping pieces and two measuring pieces, wherein the two support tables and the two supports are fixed above the support tables; and a steel mesh is arranged between the two support platforms and is arranged below the clamping piece and the measuring piece.
Preferably, the steel net has elasticity.
Preferably, the steel mesh is fixed with the two support stands.
Preferably, the clamping piece is a clamp, and the measuring piece is a length measuring ruler.
Preferably, the number of the clamping pieces and the number of the measuring pieces are both multiple.
Preferably, the clamping members and the measuring members are equal in number.
Compared with the prior art, the utility model has the following beneficial effects: steel meshes are arranged below the fastening piece and the measuring piece, so that the load piece falls to generate a buffering effect, and the load piece is prevented from injuring passers-by or other device structures due to the acceleration of gravity; the clamping piece and the measuring piece are arranged on the same vertical surface, the measuring piece is arranged right below the clamping piece, when the cable is clamped on the clamp, the cable vertically hangs down to be positioned in front of the measuring piece, the length of the cable on the ruler can be visually seen, and the defect of inaccurate reading during data reading is overcome.
