[0031] like Figure 2 , Figure 4 As shown, in a preferred embodiment, based on the above method, the sliding block 37 is further provided with a sloped platform 38 fixedly connected to its side, a pusher 39 fixedly connected to its side, a sealing line 310 fixedly connected to its side, and a sloped rod 311 fixedly connected to the inside of the kiln body 1. The function of the sliding block 37 is to drive the pusher 39 and the sealing line 310 to move.

[0032] like Figure 2 , Figure 4As shown, in a preferred embodiment, based on the above method, the inclined platform 33 and the inclined plane platform 38 are further configured as inclined planes, and both sides of the inclined plane rod 311 are configured as inclined planes. The function of the inclined plane platform 38 is to push the inclined platform 33 and the sliding block 37.

[0033] like Figure 1 , Figure 3 , Figure 5 As shown, in a preferred embodiment, based on the above method, a locking device 4 is further provided on the outside of the door 2. The locking device 4 includes a base 41, the side of the base 41 is fixedly connected to the side of the kiln body 1, a sleeve 42 is fixedly connected to the side of the base 41, a slot 43 is opened inside the sleeve 42, a telescopic spring 44 is fixedly connected to the inner wall of the slot 43, and a ball joint 45 is fixedly connected to the other end of the telescopic spring 44 away from the slot 43. The circumferential surface of the ball joint 45 is slidably connected to the inner wall of the slot 43.

[0034] like Figure 3 , Figure 5 As shown, in a preferred embodiment, based on the above method, a support plate 46 is fixedly connected to the side of the door 2, a buckle 47 is fixedly connected to the side of the support plate 46, and a slot 48 is provided on the side of the buckle 47. The function of the slot 48 is to hold the ball 45.

[0035] like Figure 3 , Figure 5 As shown, in a preferred embodiment, based on the above method, the number of the sleeve 42, the slot 43, the telescopic spring 44 and the ball 45 is set to two, and they are symmetrical to each other along the vertical central axis of the base 41.

[0036] like Figure 3 , Figure 5 As shown, in a preferred embodiment, based on the above method, the ball 45 slides on the inner wall of the slot 43, and the number of slots 48 is set to two, which are symmetrical to each other along the vertical central axis of the buckle 47. The function of the slot 43 is to allow the ball 45 to slide.

[0037] Specifically, when using this annealing kiln quick docking device: First, when the annealing kiln needs to be used, the quick docking device 3 can be used.

When the push rod 34 and push bar 39 move, they will drive the sealing line 1 35 and sealing line 2 310 to move. Thus, when the door is closed, the sealing line 1 35 and sealing line 2 310 will seal the gaps on the door body. In this way, the quick seal can instantly block the airflow exchange after the sealing line docking and opening and closing, allowing the temperature field to quickly return to stability and avoid batch product defects caused by process interruption.

[0038] The force of manually closing the door 2 can move the support plate 46 towards the kiln body 1. When the support plate 46 moves, it will move the buckle 47. When the buckle 47 moves towards the kiln body 1, it will pass through the middle of the sleeve 42. When the buckle 47 passes through the middle of the sleeve 42, the buckle 47 will press against the ball 45. When the ball 45 is pressed by the buckle 47, it will retract backward due to the telescopic spring 44. When the front end of the buckle 47 passes through the middle of the sleeve 42, the ball 45 will be locked in the slot 48 of the buckle 47 due to the restoring force of the telescopic spring 44, thereby locking the door 2. The locking device 4 can apply the clamping force more stably, avoid uneven locking force caused by the shaking of the door 2, and extend the service life of the sealing line.

[0039] All technical features in this embodiment can be freely combined according to actual needs.

[0040] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
