Description

Technical Field

[0001] This utility model relates to the field of high temperature testing machines, and in particular to a high-safety high temperature testing machine. Background Technology

[0002] High-temperature testing machines are used to expose samples to high temperatures and dry air. They are commonly used for screening components and complete machines, aging tests, life tests, accelerated life tests, evaluation tests, and also play an important role in the verification of failure analysis.

[0003] The fire extinguishing structures of high-temperature testing machines are mostly not freely selectable, which means they cannot be replaced according to the type of material to be tested, making them inconvenient and unable to guarantee safety.

[0004] Therefore, it is necessary to propose a high-safety high-temperature testing machine to solve the above problems. Utility Model Content

[0005] The main objective of this invention is to provide a high-safety high-temperature testing machine that can effectively solve the problems in the background technology.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A high-safety high-temperature testing machine includes a high-temperature testing machine body, a movable strip rotatably connected to the bottom of the high-temperature testing machine body, a safety protection seat installed at the bottom of the high-temperature testing machine body, positioning components symmetrically and movably connected to both sides of the inner cavity of the safety protection seat, a heat dissipation component installed in the inner cavity of the safety protection seat, a fire extinguishing component installed on the outer wall of the high-temperature testing machine body, a fire extinguisher installed on the top of the fire extinguishing component, and a locator movably connected to the side of the top of the fire extinguishing component.

[0008] Preferably, an alarm light and a control panel are installed on the top of the high-temperature testing machine body, a bidirectional lead screw is rotatably connected to the inner cavity of one end of the safety protection seat, and a guide rod is installed in the inner cavity of the other end of the safety protection seat.

[0009] Preferably, the two ends of the positioning component are symmetrically and movably connected to the two ends of the inner cavity of the safety protection seat. One end of the positioning component is threaded to a bidirectional lead screw, and the other end of the positioning component is sleeved on the outer wall of the guide rod. Both the positioning component and the safety protection seat are provided with heat dissipation grooves.

[0010] Preferably, the heat dissipation component includes a cooling fan and a dust filter. The dust filter is installed on top of the cooling fan. A through groove is provided at the bottom of the high-temperature testing machine body. The movable bar is rotatably connected to the inner cavity of the through groove. A limit block is installed in the inner cavity of the through groove. The movable bar can only rotate toward the top of the inner cavity of the high-temperature testing machine body.

[0011] Preferably, a feed pipe is installed at the bottom of the fire extinguishing assembly, and a spray nozzle is installed at the other end of the feed pipe. A solenoid valve is connected to the outer flange of the feed pipe. The spray nozzle is located in the inner cavity of the high-temperature testing machine body. A temperature sensor is installed in the inner cavity of the high-temperature testing machine body. The temperature sensor is electrically connected to the solenoid valve. When the temperature detected by the temperature sensor exceeds a preset threshold, the solenoid valve is activated. The other end of the feed pipe passes through the bottom of the fire extinguishing assembly and is connected to the fire extinguisher.

[0012] Preferably, the locator is attached to the outer wall of the fire extinguisher, and fixing rods are symmetrically installed in the inner cavities on both sides of the top of the fire extinguishing assembly.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. This high-safety high-temperature testing machine uses a bidirectional lead screw to move two positioning components, which facilitates the positioning of the machine body. Combined with the heat dissipation grooves, it facilitates heat dissipation for the machine body.

[0015] 2. This high-safety high-temperature testing machine, through its heat dissipation components, can blow cooling air towards the bottom of the machine body. At this time, the movable strip can be moved to the top, allowing the air to enter the inner cavity of the machine body through the through slot. Under normal conditions, the movable strip can block the through slot, which can prevent heat loss and prevent foreign objects from entering.

[0016] 3. This high-safety high-temperature testing machine is equipped with a fire extinguisher. In the event of a malfunction during the testing of the machine itself, the fire can be extinguished in conjunction with the material conveying pipe and the spray nozzle. This improves the safety of the high-temperature testing machine during testing. The locator allows for the installation of fire extinguishers of various sizes. Attached Figure Description

Heat dissipation grooves 7 are provided at both the positioning component 8 and the safety protection seat 6. The heat dissipation component 9 includes a cooling fan and a dust filter. The dust filter is installed on the top of the cooling fan. A through groove 4 is provided at the bottom of the high temperature testing machine body 1. The movable bar 5 is rotatably connected to the inner cavity of the through groove 4. A limit block is installed in the inner cavity of the through groove 4, so that the movable bar 5 can only rotate towards the top of the inner cavity of the high temperature testing machine body 1. A feed pipe 16 is installed at the bottom of the fire extinguishing assembly 13, and a spray nozzle 17 is installed at the other end of the feed pipe 16. A solenoid valve is connected to the flange on the outer wall of the feed pipe 16. The spray nozzle 17 is located in the inner cavity of the high temperature testing machine body 1. A temperature sensor is installed in the inner cavity of the high temperature testing machine body 1. The temperature sensor is electrically connected to the solenoid valve. When the temperature detected by the temperature sensor exceeds a preset threshold, the solenoid valve is activated. Positioner 14 is attached to the outer wall of fire extinguisher 15.
