Description

Technical Field

[0001] The utility model relates to the technical field of protection, and more specifically, to a metal protective shell. Background Art

[0002] Silicon carbide heating element is a commonly used heating element. Due to its advantages such as simple and convenient operation, long service life, and wide application range, it has become one of the most durable and cost-effective heating materials.

[0003] The silicon carbide material itself is relatively fragile. The heating element without a protective shell is easily damaged by external physical impacts or vibrations, especially in industrial production sites, where it is vulnerable to equipment operation or human collisions. The surface of the silicon carbide heating element without a protective shell is prone to accumulate dust, grease, or other pollutants, which not only affects the heating effect and temperature control but also increases the complexity of cleaning and maintenance, reducing the reliability and stability of the equipment.

[0004] In view of this, there is an urgent need for a metal protective shell to improve the deficiencies of the existing technology. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a metal protective shell to solve the problems raised in the above background art.

[0006] To achieve the above purpose, the utility model provides a metal protective shell, including an outer frame assembly. The outer frame assembly includes a frame body with through holes at both end faces. One end face of the outer frame is fixedly connected with a baffle, which is used to prevent the silicon carbide heating element from slipping. A stopper is fixedly connected to the side of the frame body away from the baffle. The stopper is made of elastic material and can be pressed downwards. Several empty windows are provided on the side of the frame body close to the baffle, which enables faster temperature conduction. A through hole is provided on the side of the frame body close to the stopper, and a fixing component is fixedly connected at the through hole, which is used to fix the device.

[0007] As a further improvement of this technical solution, a first fixing hole is provided on the lower surface of the frame body. The first fixing hole is arc-shaped, and a second fixing hole is provided on one side of the first fixing hole. The second fixing hole is H-shaped and is used for the silicon carbide heating element.

[0008] As a further improvement of this technical solution, the fixing component includes a movable page, which is rotatably connected to the frame body. A through hole is provided on the surface of the movable page, and the movable page rotates around the frame body. The movable page is used to fix the device and can also fix the silicon carbide heating element.

[0009] As a further improvement of the technical solution, the fixing component includes a fixing page, the fixing page is fixedly connected to the frame body, through holes are provided on the surface of the fixing page, a reinforcing block is fixedly connected to the upper surface of the fixing page, the reinforcing block is used to enhance the connection strength of the fixing page, and the other end of the reinforcing block is fixedly connected to the frame body.

[0010] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0011] For this metal protective shell, the provided protective shell can effectively prevent the silicon carbide heating element from directly contacting external physical impacts, vibrations or accidental collisions, thereby reducing the risk of breakage or cracks, extending the service life, greatly reducing raw materials, and lowering production costs. The protective shell can effectively reduce heat dissipation. Especially during high-temperature heating, it can better concentrate and maintain heat energy, improve heating efficiency, and reduce energy consumption. The protective shell can prevent pollutants such as dust and grease from entering the surface of the silicon carbide heating element, reduce the frequency and complexity of cleaning and maintenance, and improve the long-term reliability and stability of the equipment. The hollow design of this outer shell not only reduces the cost of the metal frame but also enables faster heat dissipation. BRIEF DESCRIPTION OF THE DRAWINGS

When it reaches the position of the baffle 11, the baffle 11 restricts the base of the device within the device. Release the stopper 12, and the stopper 12 restricts the base of the silicon carbide heating element. The empty windows 103 on one side of the frame body 10 facilitate the heat conduction of the silicon carbide heating element. Fix the device through the fixing assembly 2, that is, complete the socket protection shell for the silicon carbide heating element.

The fixed page 21 fixes the device, and the fixing strength of the device is improved through the reinforcing block 22.

[0025] When a metal protective case in this embodiment is specifically used, first press the stopper 12. When the stopper 12 is pressed flush with the frame 10, slide the base of the silicon carbide heating element into the device. When reaching the position of the baffle 11, the baffle 11 restricts the base of the device within the device. Release the stopper 12, and the stopper 12 restricts the base of the silicon carbide heating element. The empty window 103 on one side of the frame 10 facilitates the heat conduction of the silicon carbide heating element. The first fixing hole 101 is adjusted to an appropriate angle according to different angles to fix the device. When it is necessary to restrict the silicon carbide heating element, the silicon carbide heating element is fixed through the second fixing hole 102. The device is fixed by the fixing component 2.
