Technical Field

[0001] This utility model belongs to the technical field of hard ice cream machines, specifically relating to a door sealing structure for a hard ice cream machine and a throat seat. Background Technology

[0002] In existing technology, the dispensing port of a hard ice cream machine is typically sealed by locking the cover with two nuts, using the tightening force of the nuts to compress the sealing ring. When dispensing is needed, the cover at the dispensing port is opened by loosening the nuts several turns and rotating the cover to a certain angle. Because this structure requires repeated tightening of the nuts during opening and closing, the operation is cumbersome; furthermore, if the nuts are not fully tightened, the sealing ring will not be fully compressed, affecting the sealing effect and potentially causing material leakage. Utility Model Content

[0052] Example 1

[0053] Combination Figures 1 to 10As shown, this utility model provides a door sealing structure for a throat seat, comprising: a throat seat body 1 with a discharge port 110 thereon; a rocker arm 2 having a rotating end 210 and a driven end 220, the rotating end 210 being rotatably connected to the throat seat body 1; a door cover 3 connected to the driven end 220; and an eccentric handle 4 rotatably connected to the driven end 220. The eccentric handle 4, under forward rotation, abuts against the door cover 3 to seal the discharge port 110, or the eccentric handle 4, under reverse rotation, separates from the door cover 3 to disengage the door cover 3 from the discharge port 110.

[0054] Specifically, the throat seat door sealing structure of this utility model is applied to a hard ice cream machine. When it is necessary to seal the outlet 110, the door cover 3 moves to the outlet 110 under the swing action of the swing rod 2. Then, the eccentric handle 4 is rotated in the forward direction. At this time, the eccentric handle 4 abuts against the door cover 3, applying a force to the door cover 3 in the direction of the throat seat body 1, thereby sealing the outlet 110 and preventing material leakage. When it is necessary to discharge, the eccentric handle 4 is rotated in the reverse direction. At this time, the eccentric handle 4 will not abut against the door cover 3, and the eccentric handle 4 will separate from the door cover, no longer applying a force to the door cover 3 in the direction of the throat seat body 1, thereby causing the door cover 3 to detach from the outlet. At this time, the door cover leaves the outlet under the swing action of the swing rod 2, and the discharge can be performed.

[0055] Compared with the prior art, this utility model abandons the existing method of locking the door cover with nuts and adopts a structure that combines a swing rod and an eccentric handle, making the opening and closing of the door cover simpler and more efficient. Moreover, the eccentric action of the eccentric handle is used to lock the door cover, preventing material leakage due to the door cover not being locked.

[0056] In this embodiment, the outer contour of the eccentric handle 4 has a locking part 410 and an unlocking part 420. It should be noted that by rotating the eccentric handle forward or backward, the locking part 410 or the unlocking part 420 is positioned directly opposite the door cover 3. Specifically, when the eccentric handle 4 is rotated forward, the locking part 410 is positioned directly opposite the door cover 3, and the locking part 410 abuts against the door cover 3. The locking part 410 exerts a downward force on the door cover 3 towards the throat seat body 1 (i.e., the eccentric handle). A force is applied to the door cover 3 in the direction of the throat seat body 1 to cover and seal the discharge port 110; under the reverse rotation, the eccentric handle 4 will be positioned so that the unlocking part 420 is facing the door cover 3, the unlocking part 420 is separated from the door cover 3, and the unlocking part 420 no longer exerts a downward force on the door cover 3 in the direction of the throat seat body 1 (i.e., the eccentric handle no longer applies a force on the door cover 3 in the direction of the throat seat body 1), so that the door cover 3 is disengaged from the discharge port 110.

[0057] The eccentric handle 4 is rotatably connected to the driven end 220 via a rotating shaft, allowing the eccentric handle 4 to rotate forward or backward relative to the rocker arm 2. Regarding the structure of the eccentric handle in this embodiment, the distance between the locking part 410 and the rotating shaft of the eccentric handle 4 is a first distance; the distance between the unlocking part 420 and the rotating shaft of the eccentric handle 4 is a second distance; the first distance is greater than the second distance.

[0058] Because the distances between the locking part 410, the unlocking part 420, and the rotating shaft are different, when the position of the swing arm 2 remains unchanged, if the locking part 410 is facing the door cover 3, the locking part 410 can exert a force on the door cover 3 to press down on the throat seat body 1; however, when the unlocking part 420 is facing the door cover 3, due to the distance change, the unlocking part 420 does not exert a force on the door cover 3 to press down on the throat seat body 1. Under the action of losing the downward pressure, the door cover 3 moves towards the eccentric handle and disengages from the discharge port 110.

[0059] In this embodiment, the door cover 3 is provided with an inwardly recessed limiting groove 310; the limiting groove 310 slides in contact with the locking part 410. The locking part 410 of the eccentric handle 4 enters the limiting groove 310. Utilizing the clearance design of the limiting groove 310, the thickness of both the door cover and the eccentric handle becomes thinner, and the limiting groove 310 can also limit the eccentric handle 4.

[0060] In this embodiment, regarding the swing of the swing rod 2, the swing rod 2 has a switchable first position and a second position relative to the throat seat body 1. When the swing rod 2 is in the first position, the door cover 3 coincides with the discharge port 110 under the rotation of the swing rod 2. At this time, the door cover 3 can be closed and sealed by rotating the eccentric handle 4 in the forward direction. When the swing rod 2 is in the second position, the door cover 3 is misaligned with the discharge port 110 under the rotation of the swing rod 2. At this time, the door cover 3 no longer seals the discharge port, so that the discharge port 110 is exposed for material discharge.

[0061] Furthermore, the rotating end 210 is rotatably connected to the throat seat body 1 via a limiting assembly; the limiting assembly includes a limiting base 120 and a limiting nut 130, the limiting base 120 being disposed on the throat seat body 1; the limiting base 120 passes through the rotating end 210 and engages with the limiting nut 130. Specifically, the limiting base 120 is fixedly connected to the throat seat body 1, and a connecting shaft is provided on the limiting base 120. The connecting shaft passes through the rotating end 210 and engages with the limiting nut 130. It should be noted that the limiting nut 130 and the connecting shaft are only engaged, not tightened. Therefore, the cooperation between the limiting base 120 and the limiting nut 130 only restricts the displacement of the swing rod 2 in the axial direction of the connecting shaft, and the swing rod 2 can oscillate circumferentially relative to the limiting base 120.

[0062] In this embodiment, the door cover 3 is connected to the driven end 220 via a movable structure. The movable structure includes a fixed post 230 and an assembly groove 320 that engages with the fixed post 230. The fixed post 230 is disposed on the driven end 220, and the assembly groove 320 is correspondingly disposed on the door cover 3. Through the engagement of the fixed post 230 and the assembly groove 320, the outer wall of the fixed post 230 slides in contact with the inner wall of the assembly groove 320. The engagement of the fixed post and the assembly groove connects the swing arm 2 to the door cover 3, allowing the door cover 3 to swing synchronously when the swing arm 2 swings. In other embodiments, the fixed post 230 is disposed on the door cover 3, and the assembly groove 320 is correspondingly disposed on the driven end 220.

[0063] Furthermore, there is a movable space between the assembly groove 320 and the fixing post 230; when the cover 3 seals the discharge port 110, the volume of the movable space decreases; when the cover 3 detaches from the discharge port 110, the volume of the movable space increases. This embodiment reduces hard collisions between components and extends service life by reserving movable space between the assembly groove 320 and the fixing post 230.

[0064] In one embodiment, a sealing ring is provided on the side of the door cover 3 corresponding to the throat seat body 1. When the eccentric handle 4 rotates, it abuts against the door cover 3, causing the door cover 3 to exert pressure on the throat seat body 1. The sealing ring between the door cover 3 and the throat seat body 1 deforms under this pressure, filling the gap between them and improving sealing reliability. It should be noted that the sealing ring can be a solid or hollow ring. During the locking process of the door cover 3, the compression of the sealing ring changes unstablely. The hollow ring exhibits more stable compression, and its sealing effect on the throat seat's door sealing structure is particularly significant. The hollow sealing ring is detachable from the door cover 3 for easy disassembly, cleaning, and repositioning.
