Description

Technical Field

[0001] This utility model relates to the field of heating furnace technology, specifically a high-temperature vertical furnace. Background Technology

[0002] High-temperature tube furnaces are divided into horizontal and vertical types. Vertical furnaces are used for high-temperature heat treatment of materials and workpieces in a vertical furnace chamber. They can be applied to processes such as sintering, annealing, and tempering, and are suitable for experimental and small-batch production.

[0003] The doors of existing high-temperature vertical furnaces are all operable. For example, a movable openable vertical tube furnace is disclosed in the prior art patent number CN202121458453.0, whose tube furnace box includes a first door and a second door, and the first door and the second door are rotatably connected by a rotating hinge on the back.

[0004] Even after the furnace door is opened, the furnace chamber remains at a high temperature. Current technology cannot secure the opened furnace door, which means that workers could easily be burned if the opened furnace door rotates accidentally. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a high-temperature vertical furnace, which solves the problems existing in the prior art.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a high-temperature vertical furnace, including a base, a furnace body is provided on the base, a hinge is provided on the furnace body, and a furnace door is hinged to the furnace body through the hinge. The furnace door is provided with a latch for fixed connection with the furnace body, and a handle is also provided on the furnace door. A furnace tube is vertically arranged between the furnace body and the furnace door, and an air inlet is provided at one end of the furnace tube, and an exhaust outlet is provided at the other end of the furnace tube. Both the air inlet and the exhaust outlet are connected to the furnace body. An inverted L-shaped protrusion is provided on the rear side of the furnace door, and an insertion hole is provided on the vertical section of the protrusion. The furnace body is provided with a guide block, and a positioning rod that matches the insertion hole is slidably connected to the guide block in the front-back direction. The positioning rod is provided with an elastic telescopic component that is connected to the guide block.

[0007] Preferably, the elastic telescopic component includes a first mounting block and a second mounting block, a spring is provided between the first mounting block and the second mounting block, the spring is sleeved on the outside of the positioning rod, a bolt is connected between the first mounting block and the guide block, a connecting sleeve is provided on the second mounting block, a connecting block is provided on the positioning rod, the connecting sleeve is sleeved on the connecting block, and a bolt is provided between the connecting sleeve and the connecting block.

[0008] Preferably, the positioning rod passes through mounting block one and mounting block two.

[0009] Preferably, the handle is provided with a stop bar, which has an inverted L-shaped structure.

[0010] Preferably, the bottom of the stop bar is located on the right side of the mounting block two.

[0011] Preferably, the bottom of the stop bar is higher than the top of the spring.

[0012] This invention provides a high-temperature vertical furnace. Compared with the prior art, it has the following advantages: 1. In this high-temperature vertical furnace, when the furnace door is opened, the convex rod rotates accordingly. By pulling the positioning rod, the elastic telescopic component is stretched. Then, the positioning rod is released, and the elastic telescopic component is reset and compressed, so that the positioning rod is inserted into the hole of the convex rod, thereby fixing the furnace door. This prevents the furnace door from accidentally rotating and scalding workers after it is opened.

[0013] 2. This high-temperature vertical furnace has a stop bar connected to the handle. When the furnace door is opened, the second mounting block will block the stop bar, so that the worker will not forget to pull the second mounting block, thus avoiding the worker forgetting to fix the furnace door.

Detailed Implementation

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] See Figures 1-4 This utility model provides the following two technical solutions: First embodiment: A high-temperature vertical furnace includes a base 1, a furnace body 2 is provided on the base 1, a hinge 4 is provided on the furnace body 2, and a furnace door 3 is hinged to the furnace body 2 through the hinge 4. A latch 5 is provided on the furnace door 3 for fixed connection with the furnace body 2, and for fixing the furnace door 3 after it is closed. A handle 6 is also provided on the furnace door 3 for pulling the furnace door 3. A furnace tube 7 is vertically provided between the furnace body 2 and the furnace door 3. An air inlet 8 is provided at one end of the furnace tube 7, and an exhaust outlet 9 is provided at the other end of the furnace tube 7. Both the air inlet 8 and the exhaust outlet 9 are connected to the furnace body 2. A pressure gauge is also provided on the air inlet 8. In order to fix the open furnace door 3, an inverted L-shaped protrusion 10 is provided on the rear side of the furnace door 3. An insertion hole 11 is provided on the vertical section of the protrusion 10. The protrusion 10 is inverted L-shaped so that the insertion hole 11 is located below the furnace door 3, which makes it easier for the subsequent positioning rod 13 to be inserted into the insertion hole 11. In order to insert the positioning rod 13 into the insertion hole 11, a guide block 12 is provided on the furnace body 2. The positioning rod 13, which matches the insertion hole 11, is slidably connected to the guide block 12 in the front-back direction. The positioning rod 13 is provided with an elastic telescopic component connected to the guide block 12. The elastic telescopic component can apply elastic force to the positioning rod 13 to ensure that it is stably inserted into the insertion hole 11, so that the protruding rod 10 cannot rotate. Thus, the furnace door 3 is fixed after it is opened and will not rotate accidentally, so that the furnace door 3 will not accidentally burn the workers.

[0018] The elastic telescopic assembly includes mounting block 14 and mounting block 25. A spring 16 is provided between mounting block 14 and mounting block 25. The spring 16 is sleeved on the outside of the positioning rod 13. A bolt 17 connects mounting block 14 and guide block 12, making the mounting block 14 and guide block 12 detachable. A connecting sleeve 18 is provided on mounting block 25, and a connecting block 19 is provided on the positioning rod 13. The connecting sleeve 18 is sleeved on the connecting block 19, and a bolt 20 is provided between the connecting sleeve 18 and the connecting block 19, making the mounting block 25 detachable from the positioning rod 13. When mounting block 25 is pulled, the connecting sleeve 18 pulls the connecting block 19, which causes the positioning rod 13 to move on the guide block 12, thereby stretching the spring 16.

[0019] To better guide mounting block 2 15, positioning rod 13 passes through mounting block 1 14 and mounting block 2 15. Positioning rod 13 can also be guided by mounting block 1 14, thus improving stability during movement.

[0020] The second implementation differs from the first in that: when opening the furnace door 3, it is often easy to forget to use the positioning rod 13 to fix the furnace door 3 in the insertion hole 11. Therefore, a stop rod 21 is provided on the handle 6. The stop rod 21 has an inverted L-shaped structure. The bottom of the stop rod 21 is located on the right side of the mounting block 2 15. The bottom of the stop rod 21 is higher than the top of the spring 16. When the furnace door 3 is opened, the handle 6 will drive the stop rod 21 to rotate. At this time, the stop rod 21 will be blocked by the mounting block 2 15, so the furnace door 3 cannot be opened further. This reminds the worker to pull the mounting block 2 15 forward, so that the positioning rod 13 can move forward. Since the stop rod 21 is higher than the spring 16, it is not obstructed when rotating with the furnace door 3. After opening the furnace door 3, the mounting block 2 15 can be released, and the furnace door 3 can be fixed by the positioning rod 13.

[0021] Furthermore, all content not described in detail in this specification is existing technology known to those skilled in the art, and the model parameters of each electrical appliance are not specifically limited; conventional equipment can be used.

[0022] In use, unlock 5 and rotate the furnace door 3 via the stop bar 21 and hinge 4. At this time, the stop bar 21 will be blocked by the second mounting block 15, which will remind the worker to pull the second mounting block 15, so that the spring 16 is stretched and drives the positioning rod 13 forward. At this time, the stop bar 21 can rotate with the furnace door 3 without obstruction. When it is opened to the designated position, release the second mounting block 15, and the spring 16 will compress and drive the positioning rod 13 to insert into the insertion hole 11, thereby fixing the furnace door 3 and preventing the furnace door 3 from accidentally rotating and burning the worker.
