By means of the elastic connection component (300), the structure allows the cooker lid (400) to be adapted to a non-horizontal table.

Description

Lifting pot cover connecting structure

[0001] The utility model relates to the technical field of cooking equipment, in particular to a lifting pot cover connecting structure.

Background technique

[0002] With the development of the economy and society, there has been a cooking appliance that uses steam to heat food, a steam energy steamer. A steam energy steamer is a cooking utensil that cooks food by steam heating. Using cockroaches, the food to be cooked is placed in a steaming pan or a steaming tablet, and the steaming pan or steaming tablet is placed in the inner pot, and the pot is covered. The inner pot is closed, and high pressure steam is introduced into the inner pot to cook the food in the pot.

[0003] Based on this new type of cooking utensils, more and more restaurants and restaurants use this cooking method to achieve a steamed ready-to-eat dining mode. This kind of dining mode requires the waiter to perform the folding operation on the lid. During the whole process, the waiter needs to move back and forth many times. In order to maintain good service quality, multiple waiters need to be configured, resulting in high labor costs. In order to reduce labor costs, the industry has developed a technology for automatic lift lids. The application number is: 201520139521.5 The Chinese utility model patent discloses a dining table having a lifting type cover, comprising a cover body located above the dining table, and a telescopic rod driving the lifting and lowering of the cover body. The telescopic rod can drive the cover body to realize automatic lifting above the dining table, thereby greatly reducing the labor of the waiter and reducing the labor cost, but the following disadvantages exist: The lid between the lid and the telescopic rod is rigidly connected, and when the table is inclined, The lid does not cover the table well. Under the impact of the telescopic rod, the joint between the lid and the telescopic rod is prone to loosening.

technical problem

In view of the above, the object of the present invention is to overcome the deficiencies of the prior art and to provide a lifting type lid connection structure that can adapt to the tilting of the table top.

Problem solution

Technical solution

[0005] In order to solve the above technical problem, the utility model adopts the following schemes:

[0006] A lifting lid connection structure includes a connecting rod and a lid, the lid is provided with a mounting hole, and the connecting The rod is connected to the mounting hole of the lid through the elastic connecting member and the rigid connecting member; the elastic connecting member comprises a hollow cylindrical elastic portion, and the outer surface of the bottom end of the hollow cylindrical elastic portion is provided with a first annular elastic portion, the hollow An outer surface of the columnar elastic portion is disposed with the second annular elastic portion between the first annular elastic portion, and a groove is formed between the first annular elastic portion and the second annular elastic portion to clamp the edge of the mounting hole to make the elastic connection The rigid connecting member comprises a connecting piece and a threaded fastener, the end of the connecting rod is nested into the hollow cylindrical elastic portion, and the threaded fastener penetrates the end of the connecting piece and the connecting rod The thread is fastened such that the first annular elastic portion is clamped between the connecting piece and the lid.

[0007] The connecting rod drives the lid to lower, and if the table is tilted (that is, the pot corresponding to the lid also appears inclined), the pot lid and the pot body are incompletely incomplete, in addition to causing steam leakage, in the pot When the cover is in contact with the pot body, a large impact is generated, and the incomplete matching of the lid and the pot body may cause damage to the joint between the connecting rod and the lid. Through the improvement of the utility model, when the table top is inclined, the lid can also completely conform to the pot body. Specifically, when the connecting rod drives the lid to contact with the pot body, the lid can be inclined to one side to adapt to the inclination of the pot body, and the elastic connecting member is elastically compressed to one side, thereby achieving complete matching with the pot body. Moreover, through the action of the rigid connecting piece, both the elastic movement and the stable connection are ensured.

[0008] In order to enhance the elastic action of the elastic connecting member, the outer surface of the hollow cylindrical elastic portion and the second annular elastic portion are disposed with a third annular elastic portion, and the second annular elastic portion and the third annular elastic portion A plurality of elastic reinforcing ribs disposed between the two are disposed between the second annular elastic portion and the third annular elastic portion to form a plurality of independent regions. When the elastic connecting piece is elastically deformed, it will be stretched or compressed, and it will be squeezed into a part of the area. By setting as above, the space required for the elastic deformation is reserved, and the recovery of the elastic deformation is also ensured, so that the lid can be better. Adapt to desktops that are not levelly set.

[0009] The bottom surface of the connecting piece forms a concave threaded fastener mounting position, and an edge portion thereof forms a hook structure to cover the first annular elastic portion. The edge portion of the connecting piece forms a hook-like structure, so that the connecting piece can also cover the first annular elastic portion in the case of non-compression, and can restrain the first annular elastic portion in the case of compression, thereby ensuring the first annular elastic portion. The department will not be deformed excessively to cause damage or premature aging.

[0010] The bottom end of the connecting rod is provided with a connecting mouth, and the lateral width of the connecting nozzle is smaller than the lateral width of the connecting rod

The connecting nozzle is provided with an internal thread; the threaded fastener is a bolt, and the bolt is threadedly connected to the connecting nozzle through the connecting piece, and the nut of the bolt presses the connecting piece. Connecting rods by setting the mouth The space is larger, and the position relative to the lid changes more, adapting to the desktop with a larger inclination.

[0011] The bottom end of the connecting rod is further provided with a handle to cover the bottom end of the connecting rod, the elastic connecting member and the mounting hole.

The handles are not only aesthetically pleasing, but also prevent dust collection on the parts at the mounting holes.

[0012] Preferably, the elastic connecting member is made of a silicone material or a rubber material.

Advantageous effects of the invention

Beneficial effect

Compared with the prior art, the utility model has the following beneficial effects: In the utility model, the design of the elastic connecting member enables the lid to adapt to the non-horizontal table top, and the joint between the connecting rod and the lid is prevented from being damaged.
