Description

Technical Field

[0001] The invention relates to a buffet stove, in particular to a buffet stove with a flip cover capable of positioning and limiting the upper cover to a certain extent after the upper cover is flipped open. Background Art

[0002] Buffet stoves are containers for food, mainly used in restaurants, restaurants and hotels. A flip cover installed above the plate can play a certain role in heat preservation. Most of the flip covers of existing buffet stoves are directly mounted on the stove frame through hinges and cannot be disassembled, which causes inconvenience when cleaning the buffet stove and easily leaves dead corners, which is not conducive to the health of users.

[0003] In order to overcome the above defects, in the patent document with publication number CN201150478, a full-flip flip cover is connected to the stove frame by a rotating handle and inner and outer fixing blocks. The structure is simple, the cover can be fully opened and the self-service dining stove is easy to disassemble and assemble. However, the defects are that the structure is complicated and the processing of parts and components is cumbersome. At the same time, the flip cover cannot be positioned at an intermediate angle, which is inconvenient to use. In addition, it does not have an end limit device for the flip cover. When the flip cover is fully opened, the lid is prone to rotate and open too quickly, and the cover handle flips back and hits the dining stove frame hard. Not only is the impact sound loud, but it is also easy to pinch fingers. Therefore, it is usually necessary to place a foot pad on the edge of the rear side of the frame to avoid hard collision.

[0004] In addition, there are also some flip-top structures on the market, which use a rotating core to squeeze the metal spring sheet it abuts against to deform the metal spring sheet to achieve positioning. However, these products currently have the following problems: since the deformation of the metal spring sheet is small, its elasticity is difficult to control and it often needs to be set very tightly, so that when rotating, the friction of the rotating core on the metal spring sheet often causes an obvious squeaking metal sound, and after long-term use, the metal spring sheet is prone to permanent deformation, which greatly reduces the positioning and buffering performance and the use effect is not ideal. Summary of the invention

[0005] In view of the above problems, the object of the present invention is to provide a flip cover buffet stove with low noise, long service life and good effect.

[0006] The technical solution adopted by the present invention is:

[0007] The utility model discloses a flip cover buffet stove, comprising a stove frame, a tray is placed in the stove frame, a full flip cover is arranged above the stove frame, base plates are respectively arranged on both sides of the stove frame, rotating support handles are respectively arranged on both sides of the flip cover, an axis disk is fixedly installed on the base plate, a rotating core is placed in the inner cavity of the axis disk, the rotating core is relatively rotatably installed in the inner cavity of the axis disk through a fixed shaft connected to the base plate, the front end of the fixed shaft extends out of the rotating core, the end of the rotating support handle is provided with a U-shaped bayonet plugged into the front end of the fixed shaft and can rotate around the shaft, the rotating support handle is synchronously rotatably connected with the rotating core through a pin, an outer drum cavity section, a half-open angle positioning pressing section and a fully open limit pressing section are formed on the inner side wall of the axis disk, the rotating core is a plastic cylindrical core, a protrusion is integrally formed on the outer peripheral edge thereof, a cavity is formed on the inner side of the protrusion, an elastic section is formed between the protrusion and the rotating core body, and the protrusion can be deformed concavely toward the cavity under extrusion.

[0008] The beneficial effects of the present invention are as follows: since the two sides of the dining stove flip cover are respectively installed on the inner sides of the two ends of the stove frame through the flip cover half-open positioning mechanism and the flip cover full-open limiting mechanism, the half-open angle positioning and the stroke end point limiting can be achieved, and the use is convenient and reliable. Moreover, the half-open angle positioning and the full-open limiting are formed by the interaction between the elastic protrusion with protrusions and the low-pressure concave effect formed by the plastic rotating core and the shaft disk. The elasticity of the plastic elastic protrusion is stable, the operation is stable and reliable, and when working, the metal friction sound is rarely emitted, and the use effect is good.

[0021] Reference Figures 1 to 11 A flip cover buffet stove of the present invention comprises a stove frame 1, a tray 2 is placed in the stove frame 1, a full flip cover 3 is arranged above the stove frame 1, generally, a handle 30 is usually arranged at the front end of the full flip cover, base plates 4 are respectively arranged on both sides of the stove frame 1, rotating support handles 7 are respectively arranged on both sides of the flip cover 3, a shaft disc 9 is fixedly installed on the base plate 4, the shaft disc can be made of metal material, a rotating core 8 is placed in the inner cavity of the shaft disc 9, the rotating core is a plastic cylindrical core, preferably an elastic plastic cylindrical core, the rotating core 8 can be relatively rotatably installed in the inner cavity of the shaft disc 9 through a fixed shaft 6 connected to the base plate 4, the front end of the fixed shaft 6 extends out of the rotating core 8, the end of the rotating support handle 7 has a U-shaped bayonet 76 inserted in the front end of the fixed shaft 8, and can rotate around the axis, and the rotating support handle 7 is connected to the rotating core 8 through a pin 70 and synchronously rotates.

[0022] Among them, referring to the figures, the inner wall of the shaft disc 9 is formed with an outer drum cavity section 91, a half-open angle positioning pressing section 92 and a fully open limit pressing section 93. A protrusion 80 is integrally formed on the outer peripheral edge of the rotating core 8, and a cavity 81 is formed inside the protrusion 80. The connecting section 82 between the protrusion 80 and the rotating core body forms an elastic part, and the protrusion 80 can be deformed inwardly toward the cavity under compression.

[0023] The shaft disc 9 has a pin insertion notch 95, and the outer peripheral edge of the rotating core 8 has a pin snap-in slot 85. The pin 70 connected to the rotating support handle 7 is snap-fitted into the pin insertion notch 95 in the pin snap-in slot 85 of the rotating core 8 to achieve embedding with the rotating core 8, so that when the flip cover is flipped, the rotating core 8 is driven to rotate synchronously.

[0024] In addition, refer to Fig.11 More preferably, the front end of the fixed shaft 6 is reinforcedly connected to the base plate 4 through a support arm 5, so that the fixed shaft is not easily deformed, and the assembly of the rotating core is more reasonable, reducing the wear of the rotating core.

[0025] refer to Figure 8 , 9 10. The working principle of the dining stove of the present invention using the above-mentioned structure flip cover is as follows, wherein when the flip cover is in a closed state, Figure 8 As shown, the bottom surface of the flip cover is in a horizontal state, the rotating handle 7 is in a vertical state, and the raised portion 80 of the rotating core 8 is located at the starting position of the outer drum cavity section 91 of the shaft disk. The outer drum cavity section 91 has enough loose space for the raised portion 80 to be placed, and the cavity section 91 has a certain length, so that when the raised portion 80 rotates less than a certain angle, it will not block and restrict its rotation. At this time, for ordinary catering consumers, the flip cover is extremely easy to operate; and when the cover is flipped to the position shown in FIG. Fig. 9 In the state shown, at this time, the raised portion rotates to the edge of the half-open angle positioning pressing section 92 and begins to resist. At this time, the raised portion 80 shrinks inwardly due to its own elasticity and the cavity 81, playing a buffering and certain clamping role, realizing the half-open positioning, and its elastic force can to a certain extent keep the lid from falling freely, the effect is just right, and when it is suitable for displaying certain products or changing plates, the lid needs to be fully opened, then refer to Fig.10 , the lid continues to be turned over, and the protrusion 80 can continue to rotate toward the fully open limit pressing section 93. At this time, the inner wall of the shaft disc continues to maintain a certain abutment force on the protrusion 80, so that the handle of the lid will not collide with the furnace frame. When the service personnel need to readjust the angle of the lid, they can turn the lid back with a little more force. At this time, because the rotating core is a plastic body with a certain elasticity and the cavity, the protrusion will not affect its reset performance even if it is pressed for a long time, and can work for a long time.

[0026] Of course, the above implementation mode is not the only limitation of the present invention, and other equivalent technical solutions should also be within the protection scope of the present invention.
