[0001] This utility model relates to the field of frying equipment technology, and more specifically, it relates to a lifting lid assembly for a pressure fryer. Background Technology
[0002] Most pressure fryer lids on the market are hinged to the body. When closed, a sealing ring on the lid's end face fits against the edge of the fryer rim for sealing. However, an external fastener is required to lock the lid in place; otherwise, it is difficult to close, resulting in poor overall sealing. Therefore, this invention proposes a lifting lid assembly for pressure fryers. Summary of the Invention
[0003] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a lifting lid assembly for a pressure fryer, which has the characteristics of novel structure and reliable sealing.

The fryer platform is provided with a lid assembly for opening and closing the pot opening. The lid assembly includes a lid body and an outer ring, the outer ring being connected to the fryer platform. An adjustment assembly is provided between the lid body and the suspension, the adjustment assembly including an adjustment frame, the adjustment frame being slidably connected to a floating frame that moves up and down, the lid body being connected to the floating frame, the floating frame having a cam hole, a cam rotating inside the cam hole, the cam being rotatably connected to the adjustment frame, and a handle for controlling the rotation being driven connected to the cam.
[0005] The present invention is further configured as follows: the outer ring is provided with an upwardly extending locking post; the bottom of the adjustment frame is provided with a locking hole for inserting the locking post; the side of the locking post is provided with a closed-ring locking groove; the adjustment frame is slidably connected with a locking fork that moves horizontally and is inserted into the locking groove; the locking fork is provided with an ear plate; the cam is drivenly connected with a linkage disc arranged coaxially with its rotation axis; a connecting rod is provided between the linkage disc and the locking fork, with one end eccentrically hinged to the linkage disc and the other end hinged to the ear plate.
[0006] The present invention is further configured such that: the outer ring is provided with two adjacent locking pins spaced at an angle of 180°.
[0007] The present invention is further configured such that the top of the locking pin has a guide structure.
[0008] The present invention is further configured such that the guide structure has a chamfer.
[0009] The present invention is further configured such that the handle is L-shaped.
[0010] The present invention is further configured such that a sealing ring is provided between the cover body and the outer ring, and the sealing ring is provided on the cover body and / or the inner ring.
[0011] The present invention is further configured such that the sealing ring is disposed on the cover body.
[0012] In summary, the present invention has the following beneficial effects: The lifting lid assembly for the pressure fryer involved in the present invention drives the cam to rotate by operating the linkage, so that the cam does not press the lid body, causing the lid body to separate from the outer ring for pre-opening of the lid assembly. Then, the lid lifting and opening function is realized by moving the suspension upward. The structure is novel, the sealing is reliable, the overall function is perfect, and the practicality is strong. Attached Figure Description

[0017] To enable those skilled in the art to better understand the technical solution of this utility model, the preferred embodiments of this utility model are described below in conjunction with specific examples. However, it should be understood that these descriptions are only for further illustrating the features and advantages of this utility model, and not for limiting the patent claims of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this utility model.
[0018] The present invention will be further described below with reference to the accompanying drawings and preferred embodiments.
[0019] Example 1
[0020] Referring to Figures 1 to 4, the lifting lid assembly for a pressure fryer involved in this embodiment includes a fryer platform 1 with a pot opening and a suspension 2 that moves up and down relative to the fryer platform. The fryer platform 1 is provided with a lid assembly 3 for opening and closing the pot opening. The lid assembly 3 includes a lid body 301 and an outer ring 302. The outer ring 302 is connected to the fryer platform 1. An adjustment assembly is provided between the lid body 301 and the suspension 2. The adjustment assembly includes an adjustment frame 4. The adjustment frame 4 is slidably connected to a floating frame 5 that moves up and down. The lid body 301 is connected to the floating frame 5. The floating frame 5 has a cam hole 6. A cam 7 that rotates inside the cam hole 6 is provided. The cam 7 is rotatably connected to the adjustment frame 4. A handle 8 that controls the rotation is connected to the cam 7. The handle 8 is L-shaped.
[0021] Furthermore, a sealing ring 303 is provided on the cover body between the cover body 301 and the outer ring 302.
[0022] In this embodiment, initially, the lid body 301 is not fully embedded in the outer ring 302. At this time, by rotating the operating handle 8, the cam 7 rotates 90° in conjunction with the handle, pressing down on the lid body 301 so that it enters the outer ring 302, achieving the closing effect of the pot lid assembly 3. Conversely, under the pressure inside the pot, the lid body 301 can float out of the outer ring 302.
[0023] Example 2
[0024] Referring to Figures 1 to 4, the lifting lid assembly for a pressure fryer involved in this embodiment is further configured based on Embodiment 1, wherein the outer ring 302 is provided with two adjacent locking pins 9 spaced at an angle of 180°, the bottom of the adjusting frame 4 is provided with a locking hole (not shown) for the locking pins to be inserted, the side of the locking pin 9 is provided with a locking groove 11 in the shape of a closed ring, the adjusting frame 4 is slidably connected with a locking fork 12 that moves horizontally and is inserted into the locking groove, the locking fork 12 is provided with an ear plate 13, the cam 7 is drivenly connected with a linkage disc 14 arranged coaxially with its rotation axis, and a connecting rod 15 is provided between the linkage disc 14 and the locking fork 12, with one end eccentrically hinged to the linkage disc and the other end hinged to the ear plate.
[0025] Furthermore, the top of the locking pin 9 has a guide structure, which is chamfered.
[0026] In this embodiment, the linkage disc 14, which rotates due to the linkage cam 7, will drive the locking fork 12 to move under the transmission action of the connecting rod 15. When the locking fork 12 moves outward, the fork head on the locking fork 12 can be engaged into the locking groove 11 to lock the pot lid when it is closed. When the locking fork 12 moves inward, the fork head on the locking fork 12 can be moved out of the locking groove 11 to unlock the pot lid.
[0027] The guide structure serves as a guide when the lock pin 9 is inserted into the lock hole.
[0028] The lifting lid assembly for a pressure fryer involved in this utility model drives a cam to rotate via a control linkage, preventing the cam from pressing the lid body and causing the lid body to separate from the outer ring for pre-opening of the lid assembly. Then, the lid is lifted and opened by moving the suspension upwards. The structure is novel, the sealing is reliable, the overall function is complete, and the practicality is strong.
