Abstract
Description
Technical Field
[0001] This utility model relates to the field of testing machine technology, and in particular to a DFN high-temperature and room-temperature testing machine. Background Technology
[0002] A high-temperature constant-temperature test chamber, also known as a high-temperature test chamber, is a device used to test and determine the performance and parameters of electrical, electronic, and other products and materials under high-temperature or constant-temperature environments. It is widely used in aerospace, automotive, home appliance, and scientific research fields. The high-temperature constant-temperature test chamber simulates a high-temperature environment through precise temperature control. When the controller receives a heating command, it outputs voltage to a relay, which, through the solid-state relay and heater, activates to bring the temperature to the set value. The cooling process is achieved through a compressor refrigeration cycle, achieving dynamic equilibrium and maintaining a constant temperature. During DFN testing, the product is tested using a high-temperature constant-temperature test chamber.
[0003] However, existing technologies still have shortcomings. The existing high-temperature constant temperature test chambers are too bulky, inconvenient to move, and not stable enough.
[0004] Therefore, we propose a DFN high-temperature and room-temperature testing machine to solve this problem. Utility Model Content
[0005] The purpose of this invention is to solve the problems mentioned in the background art and to propose a DFN high-temperature and room-temperature testing machine.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A DFN high-temperature and room-temperature testing machine includes a testing machine body; mounting shells are fixedly connected to the outer surfaces of both sides of the testing machine body; a motor is fixedly connected to one outer surface of the mounting shell; a bidirectional threaded rod is rotatably mounted on the inner surface of the mounting shell; a guide rod is fixedly connected to the inner surface of the mounting shell; a mounting block is slidably mounted on the inner surface of the mounting shell; a threaded groove is provided on one outer surface of the mounting block; a sliding hole is provided on one outer surface of the mounting block; a push block is fixedly connected to the lower surface of the mounting block; a first connecting block is fixedly connected to the lower surface of the push block; a connecting rod is rotatably mounted on the outer circular surface of the first connecting block; a second connecting block is rotatably mounted on the lower surface of the connecting rod; a mounting plate is slidably mounted on the lower surface of the second connecting block; a caster wheel is fixedly connected to the lower surface of the mounting plate; a fixing block is fixedly connected to the inner surface of the mounting shell; a support column is slidably mounted on the outer surface of the fixing block; a spring is fixedly connected to the lower surface of the fixing block; and a sliding groove is slidably mounted on the inner surface of the support column.
[0008] Preferably, the outer circular surface of the bidirectional threaded rod is rotatably mounted on the inner surface of the threaded groove; the guide rod is slidably mounted on the inner surface of the sliding hole.
[0009] Preferably, the mounting plate is slidably mounted on the inner surface of the mounting housing; the connecting rods are connected by a rotating shaft.
[0010] Preferably, the support column is slidably mounted on the outer surface of the fixing block via a groove; the support column is slidably mounted on the inner surface of the mounting shell.
[0011] Preferably, the guide rod is located below the bidirectional threaded rod; the output end of the motor is fixedly connected to one end of the bidirectional threaded rod.
[0012] In this utility model, a DFN high-temperature and room-temperature testing machine is provided. The machine consists of a testing machine body, mounting shell, motor, bidirectional threaded rod, guide rod, mounting block, threaded groove, sliding hole, push block, first connecting block, connecting rod, second connecting block, rotating shaft, mounting plate, casters, and support column. When the testing machine body is moved, the motor is started, which drives the bidirectional threaded rod to rotate. The rotation of the bidirectional threaded rod causes the mounting block to move, which in turn causes the push block to move. The push block then causes the first connecting block to move, which in turn causes the connecting rod to move, which in turn causes the second connecting block to move, which in turn causes the mounting plate to move, which in turn causes the casters to move. The casters lift the testing machine body, allowing for rapid movement of the testing machine body and improving efficiency.
[0013] In this utility model, the DFN high temperature and normal temperature testing machine, through the arrangement of support column, slide groove, fixing block and spring, the movement of the mounting block will drive the push block away from the support column, and the support column will enter the mounting shell under the action of spring rebound, which can protect the support column when the testing machine body moves.
[0014] This utility model has a reasonable structural design, is simple to operate, and has high reliability. Attached Figure Description

[0021] Furthermore, the outer circular surface of the bidirectional threaded rod 4 is rotatably mounted on the inner surface of the threaded groove 7; the guide rod 5 is slidably mounted on the inner surface of the sliding hole 8.

[0025] In this invention, when the testing machine body 1 is moved during use, the motor 3 is started, which drives the bidirectional threaded rod 4 to rotate. The rotation of the bidirectional threaded rod 4 drives the mounting block 6 to move, which in turn drives the push block 9 to move. The push block 9 then drives the first connecting block 10 to move, which in turn drives the connecting rod 11 to move. The connecting rod 11 then drives the second connecting block 12 to move, which in turn drives the mounting plate 14 to move. The mounting plate 14 then drives the caster wheel 15 to move, which lifts the testing machine body 1, allowing for rapid movement of the testing machine body 1 and improving efficiency. The movement of the mounting block 6 causes the push block 9 to move away from the support column 16, and the support column 16 enters the mounting shell 2 under the action of the spring 19, thus protecting the support column 16 when the testing machine body 1 is moved.
