[0020] The following will be combined Figure 1-Figure 3 A high and low temperature test box according to an embodiment of the utility model is described in detail.
[0021] Example:
[0022] The utility model provides a high and low temperature test box, referring to Figure 1 and Figure 2As shown, it includes a high and low temperature test host 1, a main controller 9 is arranged inside the high and low temperature test host 1, a test placement chamber 2 is arranged inside the high and low temperature test host 1, a box door 3 is hinged on the high and low temperature test host 1, a box door lock 4 is arranged on the box door 3, an electric heating component and a compression refrigeration component for high and low temperature experiments are arranged inside the high and low temperature test host 1, a main controller 9 is arranged inside the high and low temperature test host 1, the main controller 9 is a PLC controller, and the electric heating component and the compression refrigeration component are electrically connected to the main controller 9. In this structure, personnel can put the product that needs high and low temperature test into the test placement chamber 2 of the high and low temperature test host 1, and then close the box door 3, and use the box door lock 4 to lock the box door 3 and the high and low temperature test host 2, so that the test placement chamber 2 forms a closed test space, and then use the main controller 9 electric heating component and compression refrigeration component to perform durability test on the product under high and low temperature environment.
[0023] refer to Figure 1 As shown, a display 13 and a control key 14 are installed on the front side of the shell of the high and low temperature test host 1. The display 13 and the control key 14 are electrically connected to the main controller 9. This structure can adjust and display the test parameters of the high and low temperature test host 1 using the display 13 and the control key 14.
[0024] refer to Figure 1 and Figure 3 As shown, a lock handle 5 is provided on the door lock 4, an electric push rod 6 is rotatably connected to the outer shell of the high and low temperature test host 1, and the piston end of the electric push rod 6 is rotatably connected to an L-shaped lock plate 7, and the L-shaped lock plate 7 is rotatably connected to a support 8, and the support 8 is fixedly installed on the outer shell of the high and low temperature test host 1. When the door lock 4 is locked, this structure starts the electric push rod 6 to drive the L-shaped lock plate 7 to rotate on the support 8, so that the L-shaped lock plate 7 blocks the position of the lock plate 5, thereby preventing the door lock 4 from being opened during the test.
[0025] refer to Figure 3 As shown, a limit plate 23 is constructed on the support 8 to locate the maximum locking position of the L-shaped lock plate 7 to avoid damage to the lock bar 5 due to excessive compression.
[0026] refer to Figure 1 , Figure 2 and Figure 3 As shown, the electric push rod 6 is electrically connected to the main controller 9, and an unlocking button 11 and a locking button 12 are provided on the front part of the shell of the high and low temperature test host 1. The unlocking button 11 and the locking button 12 are both electrically connected to the main controller 9. In this structure, the personnel sends unlocking and locking signals to the main controller 9 by pressing the unlocking button 11 and the locking button 12, and then the main controller 9 controls the electric push rod 6 to achieve locking and unlocking of the lock handle 5.
[0027] refer to Figure 2As shown, a temperature sensor 10 is installed on the inner wall of the test placement chamber 2. The specific model of the temperature sensor 10 is 602F-3500F. The temperature sensor 10 is electrically connected to the main controller 9. This structure uses the temperature sensor 10 to detect the temperature inside the test placement chamber 2. When the temperature is higher or lower than the set dangerous temperature value, the main controller 9 will make the unlocking button 11 control invalid, so as to prevent people from opening the test placement chamber 2 at dangerous temperatures and ensure the safety of the high and low temperature test host 1 during use.
[0028] refer to Figure 2 As shown, an emergency opening button 15 is installed on the front side of the shell of the high and low temperature test host 1. The emergency opening button 15 is electrically connected to the main controller 9. When this structure encounters an emergency (such as a fire), the emergency opening button 15 can be used to force unlocking at a dangerous temperature, thereby facilitating personnel to open the box door lock 4 in time.
[0029] refer to Figure 1 As shown, an anti-accidental touch component 16 is provided outside the emergency opening button 15, and the anti-accidental touch component 16 is installed on the outer wall of the high and low temperature test host 1. This structure uses the anti-accidental touch component 16 to prevent people from accidentally touching the emergency opening button 15, thereby ensuring safe use.
[0030] refer to Figure 2 As shown, the anti-incorrect touch component 16 includes a base plate 17, which is fixedly mounted on the outer shell of the high and low temperature test host 1. A square hole 18 is provided on the base plate 17 for the emergency opening button 15 to pass through. A cover 19 is rotatably connected to the base plate 17. A connecting ear 20 is provided at the lower part of the cover 19. A U-shaped opening 21 is provided on the connection. A locking plate 22 is rotatably connected to the lower part of the base plate 17. The locking plate 22 passes through the U-shaped opening 21. This structure uses the cover 19 to cover the emergency opening button 15, and then uses the locking plate 22 to pass through the U-shaped opening 21, and rotates the locking plate 22 to the horizontal position, thereby locking the cover 19, thereby locking the position of the cover 19, and the cover 19 can be opened by reverse operation, so as to facilitate personnel to trigger the emergency opening button 15.
[0031] It should be noted that: the structure applied for in the above-mentioned embodiment is mainly used in high and low temperature test boxes, and the electric heating components and compression refrigeration components involved in the high and low temperature test host 1 are all existing equipment, the specific technology has been disclosed, and the specific main controller and its control system are all existing technologies. This application does not improve the specific internal structure and control system of the high and low temperature test host, so no further introduction is given here. In this application, the locking control program of the lock handle 5 is all existing technology, the principle has been disclosed, and this application does not improve the control program of the locking structure of the rope 8 5, so no further introduction is given here.
[0032] The implementation principle of a high and low temperature test box of the embodiment of the present application is as follows: when in use, the personnel places the product to be tested into the test placement chamber 2, and then closes the box door 3 and turns the lock handle 5 downward. At this time, the box door 3 is locked, and then the personnel presses the locking button 12. At this time, the main controller 9 controls the piston rod of the electric push rod 6 to extend, thereby pushing the L-shaped lock plate 7 to rotate on the support 8, so that the L-shaped lock plate 7 locks the position of the lock handle 5, thereby preventing the lock handle 5 from being accidentally touched during the product test and opening the box door 3. When the high and low temperature test of the product is completed, the unlocking button 11 is pressed at this time, so that the main controller 9 can control the piston rod of the electric push rod 6 to retract, thereby unlocking the lock handle 5, thereby realizing opening the box door 3;
[0033] When the above product is in the high and low temperature test, the temperature sensor 10 detects the temperature inside the test chamber 2. When the temperature is higher or lower than the set dangerous temperature value, the main controller 9 will make the unlocking button 11 control ineffective, so as to prevent personnel from opening the test chamber 2 at dangerous temperatures, thereby ensuring the safety of the high and low temperature test host 1 in use;
[0034] When encountering an emergency (such as a fire), the emergency opening button 15 can be used to force unlocking at a dangerous temperature, thereby facilitating personnel to open the door lock 4 in time.
