When the fixing block 15 is inserted into the insertion hole 14, the position of the plug block 18 and the slot 16 can be made to correspond. At this time, the elasticity of the first spring 17 can be used to push the plug block 18 onto the side wall of the slot 16 to make it stuck, thereby fixing the heat preservation cover 11. After that, part of the heat emitted by the heat preservation cover 11 will enter the heat preservation cover 11, and the heat will be collected by the heat preservation cover 11, while the heat insulation cotton 12 can keep the heat warm so that it will not cool down quickly. When the heat preservation cover 11 needs to be removed from the side wall of the furnace door body 1, the pull rod 19 is grasped and pulled, and the plug block 18 is pulled out of the side wall of the slot 16, so that the heat preservation cover 11 can be disassembled.

[0025] like Figure 1 、 Figure 2 、 Figure 4As shown, the side wall of the heat preservation cover 11 is fixed with multiple elastic sheets 2; the elastic sheets 2 are evenly distributed on the side wall of the heat preservation cover 11 and have the same structure; the side wall of the elastic sheet 2 is fixed with the same baffle 21; a second spring 22 is fixed between the elastic sheet 2 and the heat preservation cover 11; when in use, when a foreign object collides with the heat preservation cover 11, the baffle 21 can be used to block the foreign object. At this time, the baffle 21 is squeezed to cause the elastic sheet 2 to deform, and at the same time, the second spring 22 will be squeezed. Then, the baffle 21 will be pushed under the elastic action of the two, and the impact force of the foreign object hitting the baffle 21 can be buffered.

[0026] like Figure 2 、 Figure 4 As shown, the side wall of the heat preservation cover 11 is fixed with a pair of brackets 3; the brackets 3 are symmetrically arranged on both sides of the heat preservation cover 11 and have the same structure; the side wall of the bracket 3 is provided with a through hole 31; the side wall of the baffle 21 is fixed with a support rod 32; the side wall of the support rod 32 is evenly fixed with a plurality of hollow balls 33; when in use, when the baffle 21 is squeezed and lowered, the support rod 32 can pass through the through hole 31, at this time the hollow ball 33 is squeezed by the bracket 3 and contracts, and after passing through the through hole 31, it will quickly expand and reset under the elastic action of the hollow ball 33 and produce A certain vibration effect is achieved. The vibration effect can be used to vibrate off the dust and impurities attached to the side wall of the baffle 21. After that, when the baffle 21 is pushed to reset by the elastic sheet 2 and the second spring 22, the hollow ball 33 can pass through the through hole 31 again to reset it. In this process, the extrusion effect exerted by the hollow ball 33 when passing through the through hole 31 can clean the dust and impurities attached to the side wall of the baffle 21, thereby improving the service life of the baffle 21 and reducing the dust and impurities from being attached to the side wall of the baffle 21 for a long time, which can easily cause corrosion to the baffle 21.
[0027] like Figure 3As shown, the side wall of the fixing block 15 is evenly provided with a plurality of grooves 4; the side wall of the insertion hole 14 is fixedly connected to a plurality of third springs 41; the third springs 41 are evenly distributed on the side wall of the insertion hole 14 and have the same structure; the end of the third spring 41 is fixedly connected to a rubber ball 42; when in use, by inserting the fixing block 15 into the side wall of the insertion hole 14, the fixing block 15 can push the rubber ball 42 away, and when the fixing block 15 is fully inserted into the side wall of the insertion hole 14, the elasticity of the third spring 41 can be used to push the rubber ball 42 into the side wall of the groove 4, and a certain friction force will be generated when the two contact each other. In this process, the rubber ball 42 is stuck into the side wall of the groove 4, which can play a pre-fixing role when the fixing block 15 is inserted into the side wall of the insertion hole 14, thereby improving the convenience of fixing the heat preservation cover 11 and reducing the risk of the fixing block 15 slipping out of the side wall of the insertion hole 14 when the heat preservation cover 11 is accidentally pulled during installation.
[0028] like Figure 2 As shown, a pair of elastic strips 5 are fixed to the side walls of the thermal insulation cover 11; the elastic strips 5 are symmetrically arranged on both sides of the thermal insulation cover 11 and have the same structure; a pair of fixing strips 51 are symmetrically fixed to the side walls of the elastic strips 5; in use, after the thermal insulation cover 11 is installed, the elasticity of the elastic strips 5 can be used to make it fit with the side walls of the furnace door body 1, thereby sealing the gap between the thermal insulation cover 11 and the furnace door body 1 and blocking the release of part of the heat. At the same time, the wall of the elastic strips 5 can be fixed by using the fixing strips 51. In this process, the thermal insulation effect of the thermal insulation cover 11 can be further improved by the set elastic strips 5, thereby increasing the thermal insulation effect of the furnace door body 1. At the same time, the fixing strips 51 can be used to increase the service life of the elastic strips 5 and reduce the occurrence of tearing and damage due to long-term use.
[0029] like Figure 3 As shown, a pair of elastic plates 6 are fixed to the side walls of the mounting block 13; the elastic plates 6 are symmetrically arranged on both sides of the mounting block 13 and have the same structure; when in use, by inserting the fixing block 15 into the side walls of the insertion hole 14, the fixing block 15 will be squeezed into the elastic plate 6, and the elasticity of the elastic plate 6 can be used to push the fixing block 15 toward the middle of the insertion hole 14. At the same time, the fixing block 15 will also slide toward the middle of the elastic plates 6 on both sides. In this process, the elastic plates 6 can play a limiting role when the fixing block 15 is inserted into the side walls of the insertion hole 14, thereby improving the accuracy of insertion and reducing the difficulty in aligning the two during insertion, which makes the insertion process more cumbersome.
[0030] like Figure 3As shown, the side wall of the elastic plate 6 is fixedly connected with a sponge block 7; when in use, the elasticity of the elastic plate 6 can make the sponge block 7 fully contact with the side wall of the fixed block 15, and the side wall of the fixed block 15 can be wiped by the sponge block 7. In this process, the sponge block 7 can clean the dust and impurities attached to the side wall of the fixed block 15, improve the smoothness of the sliding between the fixed block 15 and the socket 14, and reduce the dust and impurities blocked between the two, which affects the sliding effect.
[0031] Working principle: When in use, the heat preservation cover 11 is attached to the side wall of the oven door body 1 so that it is placed in the middle of the mounting blocks 13 on both sides, and the fixing block 15 is inserted into the side wall of the insertion hole 14. At this time, the fixing block 15 will squeeze the insertion block 18 and push it open. When the fixing block 15 is inserted into the insertion hole 14, the position of the insertion block 18 and the slot 16 can be made to correspond. At this time, the elasticity of the first spring 17 can be used to push the insertion block 18 into the side wall of the slot 16 to make it stuck, so that the heat preservation cover 11 can be fixed. After that, part of the heat emitted by the heat preservation cover 11 will enter the heat preservation cover 11, and the heat will be collected by the heat preservation cover 11, while the heat insulation cotton 12 can keep the heat warm so that it will not cool down quickly. When the heat preservation cover 11 is to be removed from the side wall of the furnace door body 1, the pull rod 19 is gripped and pulled, and the plug 18 is pulled out of the side wall of the slot 16, so that the heat preservation cover 11 can be disassembled. When in use, when foreign objects hit the heat preservation cover 11, the baffle 21 can be used to block the foreign objects. At this time, the baffle 21 is squeezed to cause the elastic sheet 2 to deform, and at the same time, the second spring 22 is squeezed. Then, the baffle 21 is pushed by the elastic action of the two, and the impact force of the foreign objects hitting the baffle 21 can be buffered. When in use, when the baffle 21 is squeezed and drops, the support rod 32 can pass through the through hole 31. At this time, the hollow ball 33 is squeezed by the bracket 3 to shrink. When it passes through After the through hole 31 is passed, the hollow ball 33 will quickly expand and reset under the elastic action of the hollow ball 33 and produce a certain vibration effect. The vibration effect can be used to vibrate off the dust and impurities attached to the side wall of the baffle 21. After that, when the baffle 21 is pushed to reset by the elastic sheet 2 and the second spring 22, the hollow ball 33 can pass through the through hole 31 again to reset it. When in use, by inserting the fixing block 15 into the side wall of the socket 14, the fixing block 15 can push the rubber ball 42 open. When the fixing block 15 is fully inserted into the side wall of the socket 14, the elasticity of the third spring 41 can be used to push the rubber ball 42 onto the side wall of the groove 4. A certain friction force will be generated under the contact between the two. When in use, when the heat preservation cover 11 is installed The elasticity of the elastic strip 5 can be used to fit the side wall of the oven door body 1, and the gap between the heat insulation cover 11 and the oven door body 1 can be sealed to block the release of part of the heat. At the same time, the fixing strip 51 can be used to fix the wall of the elastic strip 5. When in use, by inserting the fixing block 15 into the side wall of the socket 14, the fixing block 15 will be squeezed into the elastic plate 6. The elasticity of the elastic plate 6 can be used to push the fixing block 15 toward the middle of the socket 14. At the same time, the fixing block 15 will also slide toward the middle of the elastic plates 6 on both sides. When in use, the elasticity of the elastic plate 6 can be used to make the sponge block 7 fully contact the side walls of the fixing block 15. At this time, the side walls of the fixing block 15 can be wiped by the sponge block 7.
