DETAILED DESCRIPTION OF THE INVENTION

[0020] The present utility model will be further described below in conjunction with the accompanying drawings and specific embodiments to facilitate understanding of the content of the present utility model. The methods used in the present utility model are all conventional methods unless otherwise specified; the raw materials and devices used are all conventional commercially available products unless otherwise specified.

[0021] As Figure 1-5 shown, the present utility model provides a horizontally movable furnace door, which includes a furnace chamber 1. A horizontally arranged driving slide rail 3 is provided at the top of the furnace chamber 1, and a driving sliding seat 5 is slidably fitted on the driving slide rail 3. The top of the driving sliding seat 5 rotates through rollers at both ends and moves on the driving slide rail 3. A furnace door 2 is hinged to the bottom of the driving sliding seat 5. A horizontally arranged driven slide rail 4 is provided at the bottom of the furnace door 2, and a driven sliding seat 26 is provided at the bottom of the furnace door 2. The driven sliding seat 26 rotates through rollers at the bottom and moves on the driven slide rail 4. A speed reducer 6 is further provided on the furnace chamber 1. A first gear 7 is provided above the speed reducer 6. The output shaft of the speed reducer 6 and the first gear 7 are meshed and driven by a chain. A second gear 8 is further provided on the transmission shaft of the first gear 7 and rotates synchronously with the first gear 7, and the second gear 8 is located at one end of the driving slide rail 3. A third gear 14 is provided at the other end of the driving slide rail 3. The second gear 8 and the third gear 14 are meshed and driven by a chain, and the driving sliding seat 5 is fixedly provided on the chain.

[0022] As Figure 3 shown, two groups of clamping mechanisms 12 are provided on both sides of the furnace door 2. The clamping mechanism 12 includes an electric push rod 13. The electric push rod 13 is fixedly provided on the furnace chamber 1. The driving rod of the electric push rod 13 is connected to a guide rod 16 through a steel wire rope. A first inclined surface guide block 15 and a second inclined surface guide block 18 are fixedly provided on the guide rod 16. A first clamping rod 17 and a second clamping rod 19 that cooperate with the first inclined surface guide block 15 and the second inclined surface guide block 18 are further fixedly provided on the furnace chamber 1. As Figure 6 shown, a guide sleeve 21 is provided inside the clamping rod. A telescopic rod 22 is fitted inside the guide sleeve 21. A spring 23 is sleeved on the telescopic rod 22. A first roller 24 is provided at the end of the telescopic rod 22 located inside the clamping rod. A second roller 25 is further provided inside the clamping rod. The inclined surface guide block slides between the first roller 24 and the second roller 25.

[0023] When the furnace door 2 needs to be clamped, the driving rod of the electric push rod 13 extends downward, and the guide rod 16 is pulled upward through the steel wire rope. The first inclined plane guide block 15 and the second inclined plane guide block 18 move upward following the guide rod 16. The inclined plane guide block squeezes the telescopic rod 22 to extend outward, and the spring 23 is in a compressed state until the furnace door 2 is squeezed against the furnace chamber 1. When the furnace door 2 needs to be opened, the driving rod of the telescopic rod 22 shortens upward, and the telescopic rod 22 no longer pulls the guide rod 16 through the steel wire rope. The first inclined plane guide block 15 and the second inclined plane guide block 18 move downward due to their own weight. The telescopic rod 22 shortens inward and resets under the action of the spring 23, canceling the extrusion of the furnace door 2.

[0024] A force-bearing seat 20 is fixedly arranged at the position on the furnace door 2 corresponding to the telescopic rod 22. By setting the force-bearing seat 20, when the furnace door 2 is clamped, the force-bearing area of the telescopic rod 22 on the furnace door 2 is increased, preventing excessive pressure during clamping and damaging the surface of the furnace door 2.

[0025] As Figure 7 shown, a chain tensioning mechanism 9 is arranged on the chain of the first gear 7 and the speed reducer 6. The chain tensioning mechanism 9 includes an adjusting rod 10, and a gear meshing with the chain is arranged at the end of the adjusting rod 10. A length adjusting column 11 is also fixedly arranged on the adjusting rod 10, which is used to change the extending length of the adjusting rod 10, thereby adjusting the tension degree of the chain.

[0026] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "left", "right", "up", "down", "top", "bottom", "front", "rear", "inner", "outer", "back", "middle", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present invention.

[0027] However, the above are only specific embodiments of the present invention, and the scope of implementation of the present invention cannot be limited thereby. Therefore, the replacement of equivalent components or the equivalent changes and modifications made according to the scope of patent protection of the present invention should still fall within the scope covered by the claims of the present invention.
