Description

Technical Field

[0002] High and low temperature test chamber, also known as environmental test chamber, is a key equipment used in the laboratory to simulate extreme temperature conditions to test the performance of materials and products. It can create a controllable environment from extremely low temperature to extremely high temperature, evaluate the physical and chemical changes of samples under different thermodynamic states, and ensure that they can operate or be stored normally in the actual use environment. The test objects can also be electronic and electrical components, automation components, communication components, electronic chips, automotive accessories, PCB substrates, metals, chemical materials, polymer materials, plastics, etc.

[0003] When the high and low temperature test chamber conducts a high temperature test on the test object, due to the high temperature during the high temperature test, during the long simulation experiment, after the temperature of the test object rises, the temperature sensor in the test chamber will be interfered with by the effect of thermal radiation, thereby causing the temperature sensor to fail. At the same time, when conducting a low temperature test, the temperature sensor may also fail when the temperature is too low. When the high and low temperature test chamber conducts a high and low temperature test on the test object, it is necessary to control the temperature of the temperature sensor to avoid the temperature of the temperature sensor being too high or too low.

The sliding component 10 and the top of the inner wall of the experimental box 2 are installed with a sliding component 10, and the sliding component 10 is used to push the guide tube 104 into or out of the insulation chamber 40. The rotating component 11 and the rotating component 11 are installed on one side of the inner wall of the experimental box 2. The rotating component 11 is used to trigger the liquid storage component 12. The liquid storage component 12 and the top of the temperature partition 4 are installed with a liquid storage component 12, and the liquid storage component 12 is used to insulate the internal space of the insulation chamber 40. The sliding component 10 is located at the bottom of the switching component 9, the rotating components 11 are located on both sides of the switching component 9, and the liquid storage component 12 is located on the opposite side of the switching component 9.

[0028] By setting the switching component 9, the guide tube 104 can be flexibly switched according to whether the test object is subjected to a high-temperature test or a low-temperature test. The structure is simple and easy to maintain. By setting the sliding component 10, the detection effect of the temperature sensor 50 is prevented from being reduced due to the detection temperature being too high or too low, and the test accuracy of the temperature sensor 50 on the test object is further guaranteed. By setting the rotating component 11, the linkage effect of the liquid storage component 12 is achieved. The structure is simple and easy to maintain. By setting the liquid storage component 12, the sustainable operation of the guide tube 104 for heating and cooling the insulation chamber 40 and the temperature sensor 50 is improved.

[0029] like Figures 4 to 5 As shown, the switching assembly 9 includes a slide rail 91, which is installed on the top of the temperature partition 4. A sliding base 92 is installed on the surface of the slide rail 91 for damping. A transmission rod 93 is sleeved on the top of the sliding base 92. A turntable 94 is installed on the part of the transmission rod 93 that extends out of the experimental box 2 at one end, and a gear plate 95 is installed on the other end of the transmission rod 93. A connecting rod 96 is installed on the surface of the transmission rod 93. Both ends of the connecting rod 96 are connected to rotating rods 97. The number of rotating rods 97 is set to two. The two rotating rods 97 are installed on the top of the inner wall of the experimental box 2, and one end of the rotating rod 97 is connected to a connecting rod 2 98.

[0030] When the test object is subjected to a high temperature test, the operator first pushes the turntable 94, and the turntable 94 drives the sliding base 92 to slide on the surface of the slide rail 91 through the transmission rod 93, so that the sliding base 92 drives the transmission rod 93 to slide horizontally along the slide rail 91, and the sliding base 92 drives the transmission rod 93 to slide and drives the meshing plate 95 to approach and mesh with one of the bevel gears 102; Similarly, when the test object is subjected to a low temperature test, the operator first pushes the turntable 94, and the turntable 94 drives the sliding base 92 to slide on the surface of the slide rail 91 through the transmission rod 93, so that the sliding base 92 drives the transmission rod 93 to slide in the opposite direction along the horizontal direction of the slide rail 91, and the sliding base 92 drives the transmission rod 93 to slide in the opposite direction, and at the same time drives the meshing plate 95 to approach and mesh with another set of bevel gears 102; Then the operator rotates the turntable 94 , and the gear plate 95 is driven to rotate synchronously through the transmission rod 93 while the turntable 94 rotates.

[0031] By setting the damping cooperation between the slide rail 91 and the sliding base 92, the sliding base 92 can drive the transmission rod 93, the turntable 94 and the gear plate 95 to change their positions, and the meshing state of the gear plate 95 and the two sets of screws 101 can be switched. The guide tube 104 can be flexibly switched according to whether the test object is subjected to high temperature test or low temperature test. The structure is simple and easy to maintain.

[0032] like Figures 6 to 8 As shown, the sliding assembly 10 includes a screw rod 101, the number of the screw rods 101 is set to two groups, the two groups of screw rods 101 are installed on the top of the inner wall of the experimental box 2, one end of the two groups of screw rods 101 are installed with a bevel gear 102, the two groups of bevel gears 102 are meshed with the gear plate 95, the threaded sleeve on the outer surface of the screw rod 101 is provided with a mounting bracket 103, the inner side of the mounting bracket 103 is installed with a guide tube 104, both ends of the guide tube 104 are installed with hoses 105, the number of the hoses 105 is set to two groups, one of the two groups of hoses 105 is connected to the one-way valve 126, and one end of the other group of hoses 105 is connected to a waste liquid collection box 106, and the waste liquid collection box 106 is installed on one side of the experimental box 2.

[0033] The gear plate 95 rotates while meshing with one of the bevel gears 102. The bevel gears 102 rotate while driving one of the screws 101 to rotate synchronously. Under the rotation of one of the screws 101, one of the mounting brackets 103 threadedly sleeved on the outer surface of one of the screws 101 slides horizontally along one of the screws 101. The sliding of one of the mounting brackets 103 drives one of the guide tubes 104 to slide synchronously, so that one of the guide tubes 104 enters the bottom cavity of the heat preservation chamber 40. Similarly, when the gear plate 95 rotates, it engages with another set of bevel gears 102 to rotate. When the other set of bevel gears 102 rotates, it drives another set of screw rods 101 to rotate synchronously. Under the rotation action of the other set of screw rods 101, another set of mounting brackets 103 threadedly sleeved on the outer surface of the other set of screw rods 101 slides in the horizontal direction of the other set of screw rods 101. When the other set of mounting brackets 103 slides, it drives another set of guide tubes 104 to slide synchronously, so that the other set of guide tubes 104 enters the bottom cavity of the heat preservation chamber 40.

[0034] By setting up the mounting bracket 103 and the guide tube 104 and cooperating with the damping switching effect of the switching component 9, the switching of the two groups of guide tubes 104 is realized, and the guide tube 104 is used to heat up and cool down the insulation chamber 40 and the temperature sensor 50, so as to avoid the detection effect of the temperature sensor 50 being reduced due to the detection temperature being too high or too low, and further ensure the test accuracy of the temperature sensor 50 on the test object.

[0035] like Figures 9 and 10 As shown, the rotating assembly 11 includes a gear ring 111, which is sleeved on the surface of the connection part between the rotating test table 6 and the motor 60, and a flat gear 112 is meshed on the top of the gear ring 111, and the flat gear 112 is sleeved on the surface of the rotating rod 5. The rotating assembly 11 also includes a bevel gear set 113, one group of bevel gears in the bevel gear set 113 is installed at one end of the rotating rod 5, and a rotating rod 2 114 is installed at one end of the other group of bevel gears in the bevel gear set 113, and the rotating rod 2 114 is installed. Installed on the top of the inner wall of the experimental box 2, one end of the rotating rod 114 is connected to the bevel gear set 115, one group of bevel gears in the bevel gear set 115 is installed on one side of the inner wall of the experimental box 2, one end of one group of bevel gears in the bevel gear set 115 is installed with a telescopic rod 116, one end of the telescopic rod 116 is connected to a snap ring 117, the outer surface of the snap ring 117 is sleeved with a push ring 118, one end of the push ring 118 is connected to the connecting rod 98, and the inner wall of the snap ring 117 is in contact with the arc spring leaf 122.

[0036] The sliding base 92 drives the transmission rod 93 to slide and drives the connecting rod 1 96 to slide synchronously. The connecting rod 1 96 slides and pushes the rotating rod 1 97 to rotate. The rotating rod 1 97 rotates and the other end pulls the connecting rod 2 98. The connecting rod 2 98 is forced to pull the snap ring 117 synchronously. The snap ring 117 slides and drives the telescopic rod 116 to extend and contact the arc spring 122. Under the elastic action of the arc spring 122, the arc spring 122 and the snap ring 117 are in a clamping state.

[0037] The operator first places the test object on the surface of the rotating test table 6 and fixes the test object on the surface of the rotating test table 6. Then the operator heats or cools the cavity of the experimental box 2 through the heating system or the cooling system (not marked in the figure), and changes the temperature of the test object to high or low temperature through heat transfer. The motor 60 drives the rotating test table 6 to rotate synchronously, so that the heat or low temperature in the cavity of the experimental box 2 is in full contact with the test object. At the same time, the heat or low temperature is transferred to the test object through the air guide holes 8 on the side and bottom of the inner wall of the rotating test table 6.

[0038] When the rotating test table 6 rotates close to the top of the inner wall of the experimental box 2, the connection part between the rotating test table 6 and the motor 60 drives the gear ring 111 to rotate synchronously. When the gear ring 111 rotates, it engages with the flat gear 112 to rotate. When the flat gear 112 rotates, it drives the rotating rod 5. When the rotating rod 5 rotates, it drives the temperature sensor 50 to flip over, so that the temperature sensor 50 flips over to avoid the rotating test table 6.

[0039] When the rotating rod 5 rotates, the input end of the bevel gear set 113 is driven to rotate synchronously. When the input end of the bevel gear set 113 rotates, it engages with the output end of the bevel gear set 113 and rotates synchronously. When the output end of the bevel gear set 113 rotates, the input end of the bevel gear set 2 115 is driven to rotate synchronously through the rotating rod 2 114. When the input end of the bevel gear set 2 115 rotates synchronously, it engages with the output end of the bevel gear set 2 115 and rotates synchronously. When the output end of the bevel gear set 2 115 rotates, the telescopic rod 116 and the retaining ring 117 are driven to rotate synchronously.

[0040] By setting the linkage between the gear ring 111 and the flat gear 112, the rotation avoidance effect of the temperature sensor 50 is achieved. At the same time, by setting the elastic cooperation between the telescopic rod 116 and the clamping ring 117, the linkage effect of the liquid storage component 12 is achieved. The structure is simple and easy to maintain.

[0041] like Figure 11 to Figure 12As shown, the liquid storage component 12 includes a reciprocating screw rod 121, which is installed on the top of the inner wall of the experimental box 2. An arc spring 122 is installed at one end of the reciprocating screw rod 121. The number of arc springs 122 is set to multiple groups. The multiple groups of arc springs 122 are arranged at equal angles at one end of the reciprocating screw rod 121. The material of the arc spring 122 is set to carbon spring steel. The liquid storage component 12 also includes a liquid inlet barrel 123. The number of the liquid inlet barrel 123 is set to two groups. The two groups of liquid inlet barrels 123 are both installed Installed on the top of the temperature partition 4, a piston disc 124 is installed in the internal cavity of the liquid inlet barrel 123, a push plate 125 is installed at one end of the piston disc 124, and a part of the push plate 125 extending out of the liquid inlet barrel 123 at one end is threadedly sleeved on the surface of the reciprocating screw 121, a one-way valve 126 is installed through one end of the liquid inlet barrel 123, and a one-way valve 2 127 is also installed through one end of the liquid inlet barrel 123, one end of the one-way valve 2 127 is connected to a liquid storage barrel 128 through a hard pipe, and the liquid storage barrel 128 is installed on one side of the experimental box 2.

[0042] By arranging a reciprocating screw rod 121 and an arc-shaped spring leaf 122, a linkage coordination with the switching effect of the guide tube 104 is realized. At the same time, by designing two groups of liquid inlet barrels 123 and liquid storage barrels 128, separate storage of coolant and hot water is realized, and a liquid exchange effect between the liquid inlet barrel 123 and the liquid storage barrel 128 is realized. The coolant and hot water in the guide tube 104 are supplemented through the liquid inlet barrel 123, thereby improving the sustainable operation of the guide tube 104 when performing heating and cooling protection on the insulation chamber 40 and the temperature sensor 50.

[0043] At the same time, under the clamping action between the clamping ring 117 and the arc-shaped spring leaf 122, the rotation of the clamping ring 117 drives the arc-shaped spring leaf 122 and the reciprocating screw 121 to rotate synchronously. Under the rotation action of the reciprocating screw 121, the push plate 125 threadedly sleeved on the outer surface of the reciprocating screw 121 slides back and forth along the direction of the reciprocating screw 121. Under the reciprocating sliding action of the push plate 125, the push plate 125 drives the piston disc 124 to reciprocate and squeeze and suck in the liquid inlet barrel 123.

[0044] When the piston disc 124 slides and squeezes in the internal cavity of the liquid inlet barrel 123, under the squeezing action of the piston disc 124, the coolant stored in the liquid inlet barrel 123 is squeezed to one of the groups of hoses 105 through the one-way valve 126, and enters the guide tube 104 through one of the groups of hoses 105, and the insulation chamber 40 is cooled by the guide tube 104 and the insulation layer 41. When the temperature sensor 50 flips over and enters the insulation chamber 40, the temperature sensor 50 is cooled to avoid the temperature sensor 50 being too high and causing the temperature detection accuracy to decrease. At the same time, under the continuous squeezing action of the piston disc 124, the coolant continues to enter the guide tube 104, and enters the waste liquid collection box 106 through another group of hoses 105 at the other end of the guide tube 104, thereby completing the replenishment of the coolant in the guide tube 104.

[0045] Similarly, when the piston disc 124 slides and draws suction in the internal cavity of the liquid inlet barrel 123, under the suction action of the piston disc 124, the coolant stored in the liquid storage barrel 128 flows through the hard pipe to the one-way valve 127 and enters the liquid inlet barrel 123, completing the circulation replenishment of the coolant in the liquid inlet barrel 123.

[0046] Similarly, under the rotation of another set of retaining rings 117, another set of piston disks 124 are reciprocatedly squeezed and sucked in another set of liquid inlet barrels 123, squeezing the hot water stored in another set of liquid inlet barrels 123 into another set of flow guide tubes 104, thereby insulating the heat preservation chamber 40 to prevent the temperature sensor 50 from being too low and causing a decrease in detection accuracy. At the same time, the hot water in another set of flow guide tubes 104 and the hot water in another set of liquid inlet barrels 123 are circulated and replenished until the high and low temperature test of the test object is completed.

[0047] The working principle of the technical solution provided by the present invention is as follows: When performing a high temperature test on the test object, the operator first pushes the turntable 94, and the turntable 94 drives the sliding base 92 to slide on the surface of the slide rail 91 through the transmission rod 93, so that the sliding base 92 drives the transmission rod 93 to slide horizontally along the slide rail 91. The sliding base 92 drives the transmission rod 93 to slide and drives the gear plate 95 to approach and engage with one of the sets of bevel gears 102.

[0048] Similarly, when performing a low-temperature test on the test object, the operator first pushes the turntable 94, and the turntable 94 drives the sliding base 92 to slide on the surface of the slide rail 91 through the transmission rod 93, so that the sliding base 92 drives the transmission rod 93 to slide in the opposite direction along the slide rail 91 horizontally. The sliding base 92 drives the transmission rod 93 to slide in the opposite direction and drives the meshing plate 95 to approach and engage with another set of bevel gears 102.

[0049] Then the operator rotates the turntable 94, and while the turntable 94 rotates, it drives the gear plate 95 to rotate synchronously through the transmission rod 93. While the gear plate 95 rotates, it engages one of the groups of bevel gears 102 to rotate. While one of the groups of bevel gears 102 rotates, it drives one of the groups of screw rods 101 to rotate synchronously. Under the rotation action of one of the groups of screw rods 101, one of the groups of mounting brackets 103 threadedly sleeved on the outer surface of one of the groups of screw rods 101 slides in the horizontal direction of one of the groups of screw rods 101. While one of the groups of mounting brackets 103 slides, it drives one of the groups of guide tubes 104 to slide synchronously, so that one of the groups of guide tubes 104 enters the bottom cavity of the insulation chamber 40.

[0050] Similarly, when the gear plate 95 rotates, it engages with another set of bevel gears 102 to rotate. When the other set of bevel gears 102 rotates, it drives another set of screw rods 101 to rotate synchronously. Under the rotation action of the other set of screw rods 101, another set of mounting brackets 103 threadedly sleeved on the outer surface of the other set of screw rods 101 slides in the horizontal direction of the other set of screw rods 101. When the other set of mounting brackets 103 slides, it drives another set of guide tubes 104 to slide synchronously, so that the other set of guide tubes 104 enters the bottom cavity of the heat preservation chamber 40.

[0051] The sliding base 92 drives the transmission rod 93 to slide and drives the connecting rod 1 96 to slide synchronously. The connecting rod 1 96 slides and pushes the rotating rod 1 97 to rotate. The rotating rod 1 97 rotates and the other end pulls the connecting rod 2 98. The connecting rod 2 98 is forced to pull the snap ring 117 synchronously. The snap ring 117 slides and drives the telescopic rod 116 to extend and contact the arc spring 122. Under the elastic action of the arc spring 122, the arc spring 122 and the snap ring 117 are in a clamping state.

[0052] The operator first places the test object on the surface of the rotating test table 6 and fixes the test object on the surface of the rotating test table 6. Then the operator heats or cools the cavity of the experimental box 2 through the heating system or the cooling system (not marked in the figure), and changes the temperature of the test object to high or low temperature through heat transfer. The motor 60 drives the rotating test table 6 to rotate synchronously, so that the heat or low temperature in the cavity of the experimental box 2 is in full contact with the test object. At the same time, the heat or low temperature is transferred to the test object through the air guide holes 8 on the side and bottom of the inner wall of the rotating test table 6.

[0053] When the rotating test table 6 rotates close to the top of the inner wall of the experimental box 2, the connection part between the rotating test table 6 and the motor 60 drives the gear ring 111 to rotate synchronously. When the gear ring 111 rotates, it engages with the flat gear 112 to rotate. When the flat gear 112 rotates, it drives the rotating rod 5. When the rotating rod 5 rotates, it drives the temperature sensor 50 to flip over, so that the temperature sensor 50 flips over to avoid the rotating test table 6.

[0054] When the rotating rod 5 rotates, the input end of the bevel gear set 113 is driven to rotate synchronously. When the input end of the bevel gear set 113 rotates, it engages with the output end of the bevel gear set 113 and rotates synchronously. When the output end of the bevel gear set 113 rotates, the input end of the bevel gear set 2 115 is driven to rotate synchronously through the rotating rod 2 114. When the input end of the bevel gear set 2 115 rotates synchronously, it engages with the output end of the bevel gear set 2 115 and rotates synchronously. When the output end of the bevel gear set 2 115 rotates, the telescopic rod 116 and the retaining ring 117 are driven to rotate synchronously.

[0055] At the same time, under the clamping action between the clamping ring 117 and the arc-shaped spring leaf 122, the rotation of the clamping ring 117 drives the arc-shaped spring leaf 122 and the reciprocating screw 121 to rotate synchronously. Under the rotation action of the reciprocating screw 121, the push plate 125 threadedly sleeved on the outer surface of the reciprocating screw 121 slides back and forth along the direction of the reciprocating screw 121. Under the reciprocating sliding action of the push plate 125, the push plate 125 drives the piston disc 124 to reciprocate and squeeze and suck in the liquid inlet barrel 123.

[0056] When the piston disc 124 slides and squeezes in the internal cavity of the liquid inlet barrel 123, under the squeezing action of the piston disc 124, the coolant stored in the liquid inlet barrel 123 is squeezed to one of the groups of hoses 105 through the one-way valve 126, and enters the guide tube 104 through one of the groups of hoses 105, and the insulation chamber 40 is cooled by the guide tube 104 and the insulation layer 41. When the temperature sensor 50 flips over and enters the insulation chamber 40, the temperature sensor 50 is cooled to avoid the temperature sensor 50 being too high and causing the temperature detection accuracy to decrease. At the same time, under the continuous squeezing action of the piston disc 124, the coolant continues to enter the guide tube 104, and enters the waste liquid collection box 106 through another group of hoses 105 at the other end of the guide tube 104, thereby completing the replenishment of the coolant in the guide tube 104.

[0057] Similarly, when the piston disc 124 slides and draws suction in the internal cavity of the liquid inlet barrel 123, under the suction action of the piston disc 124, the coolant stored in the liquid storage barrel 128 flows through the hard pipe to the one-way valve 127 and enters the liquid inlet barrel 123, completing the circulation replenishment of the coolant in the liquid inlet barrel 123.

[0058] Similarly, under the rotation of another set of retaining rings 117, another set of piston disks 124 are reciprocatedly squeezed and sucked in another set of liquid inlet barrels 123, squeezing the hot water stored in another set of liquid inlet barrels 123 into another set of flow guide tubes 104, thereby insulating the heat preservation chamber 40 to prevent the temperature sensor 50 from being too low and causing a decrease in detection accuracy. At the same time, the hot water in another set of flow guide tubes 104 and the hot water in another set of liquid inlet barrels 123 are circulated and replenished until the high and low temperature test of the test object is completed.
