Description
Technical field
The present invention relates to sample temperature impact test instrument technical field, specifically a kind of thermal shock test chamber.
Background technology
Impact test case in the past, cylinder can only be adopted to drive air door (turnover panel) form to realize, and the parts such as its complex structure, employing cylinder are more; And high/low temperature two kinds of temperature shock tests can only be met at most, if need to carry out high temperature-normal temperature-low-temperature impact test, then need to buy other equipment in addition, add use cost.
Summary of the invention
Because the above-mentioned defect of prior art, it is simple and can realize the impact test case of high temperature-normal temperature-low-temperature impact test that technical problem to be solved by this invention is to provide a kind of structure.
For achieving the above object, the invention provides portable impact test case, comprise low temperature chamber, hot room and mobile sample frame, below described low temperature chamber, refrigeration unit is installed, have the projection having screwed hole bottom described hot room, be equipped with leading screw in the screwed hole of described projection, described leading screw low order end is connected with sprocket wheel, described sprocket wheel and chain interoperation, described chain is driven by reducing motor; The left surface of described mobile sample frame is connected with left steel wire rope, and described left steel wire rope is connected with the left end of twin shaft cylinder; The right flank of described mobile sample frame is connected with right steel wire rope, and described right steel wire rope is connected with the right-hand member of twin shaft cylinder;
Described mobile sample frame left and right sides respectively have a hermatic door, and described hermatic door is used for when sample frame moves and box sealing;
Be provided with heater in described low temperature chamber, described heater base is provided with evaporimeter.
The invention has the beneficial effects as follows: this chamber is actually the equipment of three kinds of casings unification, it can realize impact test, fast temperature change test and thermocycling separately, can save equipment for user, and of many uses, structure is simple.

Detailed description of the invention
Below in conjunction with drawings and Examples, the invention will be further described:
As shown in Figures 1 to 4, portable impact test case, comprises low temperature chamber 1, hot room 2, mobile sample frame 3, and described mobile sample frame 3 is for placing test specimen; Below described low temperature chamber 1, refrigeration unit 11 is installed, the projection 21 having screwed hole is had bottom described hot room 2, leading screw 5 is equipped with in the screwed hole of described projection 21, described leading screw 5 low order end is connected with sprocket wheel 51, described sprocket wheel 51 coordinates with chain 52, and described chain 52 is driven by reducing motor 8;
Left surface, the right flank of described mobile sample frame 3 are connected with left steel wire rope 41 and right steel wire rope 4 respectively, and described left steel wire rope 41 is connected with the left and right end of two-way axle cylinder 12 respectively with right steel wire rope 4;
Described mobile sample frame 3 left and right sides respectively have a hermatic door 31, described raised seals door 31 for corresponding low temperature chamber 1 and hot room 2 edge mate, play effective sealing function;
See Fig. 5, be provided with heater 15 in low temperature chamber 1, described heater 15 bottom is provided with evaporimeter 14; Support wheel 13 is also had bottom described hot room 2; Described hot room 2 gate is provided with observation window 16.
See Fig. 1, Fig. 7, Fig. 8, state diagram of the present invention when Fig. 1 is for carrying out low-temperature test, when needs are transferred directly to elevated temperature impact test from low-temperature test, only need start the right side of twin shaft cylinder 12, when right side is shunk, twin shaft pneumatic cylinder 12 drives right steel wire rope 4 to move right, and right steel wire rope 4 drives mobile sample frame 3 to move right until just complete low temperature-elevated temperature impact test when reaching the state of Fig. 7
When needs carry out low temperature-normal temperature-elevated temperature impact test, first reducing motor 8 is started, reducing motor 8 drives chain 7, sprocket wheel 52, leading screw 5 to rotate, hot room 2 can be driven when leading screw 5 rotates to move to right to Fig. 8 state, now start two-way cylinder 12 right-hand member to shrink, right steel wire rope 4 can be driven during contraction to move to right, and right steel wire rope 4 drives mobile sample frame 3 to move to Fig. 8 state again.
More than describe preferred embodiment of the present invention in detail.Should be appreciated that those of ordinary skill in the art just design according to the present invention can make many modifications and variations without the need to creative work.Therefore, all technical staff in the art, all should by the determined protection domain of claims under this invention's idea on the basis of existing technology by the available technical scheme of logical analysis, reasoning, or a limited experiment.
