[0037] like Figure 1~Figure 5 As shown, this embodiment proposes a furnace door 2 maintenance locking device, which is used to lock the furnace door 2 that slides with the furnace 1, including: the furnace door 2 has a mounting groove 201; a movable plate 3 is slidably set on the furnace 1, and the movable plate 3 has a limiting groove 301; a pressure rod 4 is slidably set in the mounting groove 201, and the pressure rod 4 is engaged with the limiting groove 301 after sliding, and the sliding direction of the movable plate 3 is parallel to the sliding direction of the pressure rod 4.

[0038] In this embodiment, the furnace door 2 is provided with a mounting groove 201, the mounting groove 201 can accommodate the pressure rod 4, and the pressure rod 4 slides in the mounting groove 201; the movable plate 3 is installed on the furnace 1, and can slide along the surface of the furnace 1, and the movable plate 3 is provided with a limiting groove 301; the pressure rod 4 is slidably embedded in the mounting groove 201 of the furnace door 2, and when the pressure rod 4 slides to the set position, its end will be tightly engaged with the limiting groove 301 on the movable plate 3. The sliding direction of the movable plate 3 is parallel to the sliding direction of the pressure rod 4 in the mounting groove 201. When the movable plate 3 slides into place on the furnace 1, it can cause the pressure rod 4 to be tightly combined with the limiting groove 301 through its own movement, thereby firmly fixing the furnace door 2; on the contrary, when unlocking, the pressure rod 4 can be separated from the limiting groove 301 by properly moving the movable plate 3, so as to facilitate the opening and closing operations of the furnace door 2.

[0039] In this embodiment, when the operator needs to open the furnace door 2, the furnace door 2 can be raised by external driving, at which time, the end of the pressure rod 4 contacts the limit groove 301 to form a snap connection; when the operator wants to lower the furnace door 2, the movable plate 3 can slide along the surface of the furnace 1, so that the limit groove 301 and the pressure rod 4 cancel the snap connection, and the furnace door 2 can slide downward under the driving of the external driving. This device allows the operator to control the opening and closing size of the furnace door 2 according to his own needs, which is convenient for operation.

[0040] Optionally, it also includes: one end of the elastic member 5 acts on the inner wall of the installation groove 201, and the other end acts on the pressure rod 4, the elastic member 5 is used to provide a force to move the pressure rod 4 away from the installation groove 201; the first boss 6 is arranged at one end of the pressure rod 4 away from the elastic member 5, and after the pressure rod 4 slides, the first boss 6 is snap-fitted with the limiting groove 301.

[0041] In this embodiment, the elastic member 5 can be a compression spring. The main function of the elastic member 5 is to continuously give the pressure rod 4 an outward thrust (i.e., away from the installation groove 201) under normal conditions, ensuring that the pressure rod 4 always maintains a tendency to contact the limit groove 301, so that when not pushed by external force, the pressure rod 4 is in a locked state, effectively maintaining the closure and fixation of the furnace door 2. A first boss 6 is also provided at the end of the pressure rod 4. When the pressure rod 4 slides in the installation groove 201, the first boss 6 will form a precise snap fit with the limit groove 301 on the movable plate 3 as the pressure rod 4 moves.

[0042] Optionally, the movable plate 3 further has a positioning groove 302, which is located on one side of the limiting groove 301 and is connected to the limiting groove 301, and also includes: a positioning block 7 is arranged on one side of the first boss 6, and after the pressure rod 4 slides, the positioning block 7 is snap-fitted with the positioning groove 302.

[0043] In this embodiment, the positioning groove 302 is adjacent to the limiting groove 301 and is connected to the limiting groove 301, forming a complete guiding and positioning system. When the pressure rod 4 slides into place in the installation groove 201, in addition to the first boss 6 and the limiting groove 301 being engaged and locked to the furnace door 2, the positioning block 7 can also achieve precise engagement with the positioning groove 302 on the movable plate 3, so that the furnace door 2 is double-positioned, which improves the stability and accuracy of the furnace door 2 when it is opened, improves the reliability of the locking of the furnace door 2, and reduces the risk of the furnace door 2 loosening due to vibration, misoperation, etc.

[0044] Optionally, there are two movable plates 3, and the two movable plates 3 are slidably set on the furnace 1, and the two movable plates 3 are symmetrically arranged, and a plurality of limit grooves 301 and positioning grooves 302 are respectively distributed in an array on the two movable plates 3; there are a plurality of installation grooves 201, and the plurality of installation grooves 201 are arrayed on both sides of the furnace door 2; there are a plurality of pressure rods 4, elastic members 5, first bosses 6, and positioning blocks 7.

[0045] In this embodiment, two movable plates 3 are symmetrically slidably arranged on the kiln 1, and each movable plate 3 is evenly arranged with a number of limit grooves 301 and positioning grooves 302, in order to enhance the stability of the furnace door 2 when locked, so that the furnace door 2 can be effectively locked at multiple points. A number of mounting grooves 201 are also arranged in an array on both sides of the furnace door 2, and each mounting groove 201 contains a pressure rod 4, an elastic member 5, a first boss 6 and a positioning block 7. In other words, each mounting groove 201 area has an independent pressure rod 4 that provides a force away from the mounting groove 201 through the elastic member 5, and is engaged with the limit groove 301 on the movable plate 3 through the first boss 6, and the positioning block 7 is engaged with the positioning groove 302, forming a multi-point linkage locking mechanism. In this way, when the furnace door 2 rises, each pressure rod 4 will be aligned and locked with the limit groove 301 and the positioning groove 302 on the movable plate 3 under the action of the elastic member 5, forming a multi-point locking effect, which greatly enhances the stability and safety of the furnace door 2.

[0046] Optionally, the first boss 6 and the positioning block 7 have positioning holes 8 ; further comprising: a second boss 9 is slidably arranged on one side of the furnace 1 , and after the second boss 9 slides, it is snap-fitted with the positioning hole 8 .

[0047] In this embodiment, the first boss 6 and the positioning block 7 are both provided with positioning holes 8; the second boss 9 is slidably provided on one side of the furnace 1. When the furnace door 2 rises to a certain height, and the first boss 6 and the positioning block 7 on the pressure rod 4 are respectively engaged with the limiting groove 301 and the positioning groove 302 of the corresponding height, the second boss 9 can move in a direction close to the first boss 6 under certain conditions, and engage with the positioning holes 8 on the first boss 6 and the positioning block 7. This design means that on the basis of the original mutual engagement of the limiting groove 301 and the positioning groove 302 of the pressure rod 4 and the movable plate 3, an additional locking level consisting of the second boss 9 and the positioning hole 8 is added, so that the locking of the furnace door 2 is more secure and safe. Through this multi-level locking method, the stability of the furnace door 2 after rising and fixing is improved, and the potential safety hazards caused by the failure of a single locking are reduced.

[0048] Optionally, it further includes: a pneumatic part 10 is arranged on one side of the kiln 1 , the pneumatic part 10 has a telescopic end 1001 , and the second boss 9 is arranged on the telescopic end 1001 .

[0049] In this embodiment, the second boss 9 is mounted on the telescopic end 1001, and the pneumatic member 10 controls the position of the second boss 9 through the movement of the telescopic end 1001. When the pneumatic member 10 is working, the second boss 9 can slide on the side of the furnace 1 accordingly through the extension or retraction of the telescopic end 1001, and then dock or separate with the first boss 6 and the positioning hole 8 on the positioning block 7, thereby completing the locking of the furnace door 2.

[0050] Optionally, it further includes: a signal transmitter 11 is arranged in the positioning hole 8 for transmitting signals; and a signal receiver 12 is arranged in the second boss 9 for receiving signals sent by the signal transmitter 11 .

[0051] In this embodiment, the signal transmitter 11 is arranged in the positioning hole 8 of the first boss 6 and the positioning block 7, and its function is to transmit a specific signal, such as a radio signal, an infrared signal or an electromagnetic signal. The signal receiver 12 is embedded in the second boss 9, and its function is to capture and identify the signal from the signal transmitter 11. When the second boss 9 slides to a position aligned with the positioning hole 8, the signal receiver 12 can receive the signal sent by the signal transmitter 11, thereby realizing accurate detection and confirmation of the closed state of the furnace door 2. Once the signal receiver 12 does not receive a signal, it can immediately trigger an alarm or take corresponding protective measures, which greatly improves the safety and working efficiency of the equipment.

[0052] Optionally, it also includes: a reciprocating screw 13 is rotatably arranged on the furnace 1, and two movable plates 3 are respectively threadedly matched with the reciprocating screw 13; a driving member 14 is arranged on the furnace 1, and the driving member 14 drives the reciprocating screw 13 to rotate.

[0053] In this embodiment, the driving member 14 can be an electric motor. When the operator needs to lower the furnace door 2, the driving member 14 can be operated to rotate the reciprocating screw 13, and then the two moving plates 3 move away from each other, so that the limiting groove 301 and the positioning groove 302 on the moving plate 3 are respectively disconnected from the first boss 6 and the positioning block 7, and then the operator can lower the furnace door 2 through external driving.
