A protective frame 3 is fixedly connected to the front of the doors 2. A concave plate 4 is fixedly connected to the inner cavity of the protective frame 3. A screw 5 is rotatably connected to one side of the top of the inner cavity of the concave plate 4 via a bearing. A lifting plate 6 is threaded onto the outer surface of the screw 5. The bottom of the lifting plate 6 extends below the concave plate 4 and is fixedly connected to a pressure plate 7. A drive assembly 8 is provided on one side of the top of the inner cavity of the protective frame 3. Support assemblies 9 are provided at the four corners of the bottom of the high-temperature oven body 1. The drive assembly 8 includes a servo motor 801, the top of which is fixedly connected to the connection point of the protective frame 3. The output end of the servo motor 801 is fixedly connected to the drive gear 802. The top of the screw 5 passes through the concave plate 4 and is fixedly connected to the driven gear 803. The drive gear 802 and the driven gear 803 mesh. The four corners of the bottom of the high-temperature oven body 1 and the outside of the stud 901 are movably connected to the casters 10. A locking plate is provided on one side of the casters 10. The top of the left and right sides of the lifting plate 6 is fixedly connected to the guide plates 11. The left and right sides of the inner cavity of the concave plate 4 are provided with guide grooves 12 that cooperate with the guide plates 11. The outer surface of the guide plate 11 is slidably connected to the inner surface of the guide groove 12. The bottom of the pressure plate 7 is fixedly connected to the anti-slip pad 13. The front of the protective frame 3 is fixedly installed with the inspection plate 14 by screws.

[0033] In this embodiment: By setting up a protective frame 3, a concave plate 4, a screw 5, a lifting plate 6, a pressing plate 7, and a driving assembly 8, this utility model can conveniently press and limit the door 2 when it is opened. By setting up the above structure, it can have the function of limiting protection, thereby meeting the user's needs and avoiding potential safety hazards.

[0034] Example 2:

[0035] Reference Figure 2 and Figure 3 The support component 9 includes a stud 901, a support tube 902 is threadedly connected to the outer surface of the stud 901, a support plate 903 is fixedly connected to the bottom of the support tube 902, a rubber pad is fixedly connected to the bottom of the support plate 903, and the top of the stud 901 is fixedly connected to the connection point of the high-temperature oven body 1.

[0036] In this embodiment: By setting studs 901, support tubes 902 and support discs 903, the present invention can easily support the device and adjust its horizontal state.

[0037] The implementation principle of this utility model is as follows: When in use, the operator moves the device to the designated position using the casters 10. Then, the operator rotates the support tube 902 in sequence, causing the support tube 902 to drive the support plate 903 to rotate and move downward on the outer surface of the stud 901. This causes the support plate 903 to drive the rubber pad to move downward and contact the ground. The cooperation of the four support plates 903 and the rubber pads supports the device and adjusts its horizontal state.

[0038] Next, when the high-temperature oven body 1 needs maintenance and cleaning, the staff opens the two side doors 2. Then, the staff plugs the two side servo motors 801 into power and start the external controller of the two side servo motors 801. This causes the output end of the servo motors 801 to drive the drive gear 802 to rotate. The drive gear 802 drives the driven gear 803 to rotate. The driven gear 803 drives the screw 5 to rotate on the inner surface of the lifting plate 6. This causes the lifting plate 6 to move the pressure plate 7 downward. As a result, the pressure plate 7 moves the anti-slip pad 13 downward and presses it against the ground, thus achieving pressure and limiting protection for the oven door 2. This prevents the oven door 2 from shaking and hitting and injuring the maintenance personnel in case of an accident. This device is simple to operate and easy to use for limiting protection, thereby meeting the customer's usage needs and avoiding potential safety hazards.
