Description

Technical Field

[0001] The utility model relates to the technical field of placing plate devices, in particular to a structure for enlarging the working surface of a kitchen placing plate. Background Technique

[0002] A kitchen is a room where food can be prepared and cooked. The equipment usually included in a modern kitchen are stoves (gas stoves, electric stoves, microwave ovens or ovens), sinks (dishwashing sinks or dishwashers), and food storage equipment (such as refrigerators, freezers). However, the most important one is the placing plate, because seasonings and various materials need to be placed for daily use.

[0003] The existing Chinese patent with the publication number CN213370895U discloses a structure for enlarging the working surface of a kitchen placing plate, including a first housing. The front surface and the rear surface of the first housing are both fixedly connected with slide rails. The outer side walls of the two slide rails are slidably connected with a second housing. Four first threaded holes are symmetrically and fixedly connected to one side of the second housing, and a baffle is fixedly connected to one side of the first housing. During use, take out the four first bolts, and by sliding the second housing until the groove in the first housing is completely exposed outside, the third plate body is pushed upward by the action of the first spring and the slide rod. When the first plate body on the third plate body slides out of the groove, the second plate bodies on both sides of the first plate body are pushed outward by the action of the second spring. The second plate bodies can be buckled on the top of the first housing and used as support points to prevent the first plate body and the third plate body from sliding downward under pressure. Through the above operations, the usable area of the working surface is expanded. However, the operation of this device is complex and very cumbersome during use, greatly reducing the usability of the device in real life. Content of the Utility Model

[0004] The purpose of the utility model is to provide a structure for enlarging the working surface of a kitchen placing plate. By using this device for work, the problems that the working surface area of the kitchen placing plate is not enough or the operation is complex and very cumbersome during use are solved.

[0005] To achieve the above object, the present utility model provides the following technical solution: A structure for increasing the working surface of a kitchen placement board, including a telescopic board. The telescopic board includes a lifting assembly, and the lifting assembly includes a lifting mechanism. A driving mechanism is penetrated and engaged in the middle of the lifting mechanism. The lifting mechanism includes a fixed shaft one. At both ends of the fixed shaft one, a connecting rod one and a connecting rod two are movably arranged. At one end of the connecting rod one away from the fixed shaft one, a rotating shaft is movably arranged. At both ends of the connecting rod two, rotating shafts are movably arranged. At the upper end of the rotating shaft, a support plate is fixedly arranged. The driving mechanism includes a threaded rod. At one end of the threaded rod, a limiting block one is fixedly arranged. The other end of the threaded rod penetrates through a fixing member, and a turning handle is fixedly arranged at the other end of the threaded rod. By rotating the turning handle, the threaded rod rotates, so that the fixed shaft one moves back and forth. The fixed shaft one will cause a change in the angle between the connecting rod one and the connecting rod two, thereby realizing the lifting movement. This device has a simple structure and is very convenient to use, which improves the use efficiency and practicability of the device.

[0006] Preferably, the telescopic board includes a frame. At the upper end of the frame, a tabletop is fixedly arranged. Inside the frame, a lifting assembly is fixedly arranged. By arranging the lifting assembly inside the frame, the lifting of the tabletop is realized, which greatly improves the use efficiency and practicability of the device.

[0007] Preferably, the frame includes a frame body. At one end of the frame body, a semi-hidden door handle is fixedly arranged. At the lower end of the frame body, a slide rail is fixedly arranged. Through the arrangement of the slide rail, during use, only need to put the hand in the semi-hidden door handle and gently pull it outwards, then the telescopic board can be pulled out. It is very convenient to operate in daily use, has a simple structure, and has a low maintenance cost.

[0008] Preferably, a table board is movably arranged outside the telescopic board. The table board includes a main body. Inside the main body, a groove is opened. Through the groove opened inside, the function of pulling out the internal telescopic board outwards is realized. At the same time, the structure is optimized, making the device simple and durable, and improving the use efficiency and practicability of the device.

[0009] Preferably, a fixed shaft two is fixedly arranged inside the main body. Outside the fixed shaft two, a roller is movably arranged. By embedding the roller in the slide rail, the telescopic board can slide back and forth, reducing the labor intensity during use and being very labor-saving.

[0010] Preferably, a limiting block two is fixedly arranged at the lower end of the telescopic board. By embedding the limiting block two in the groove, when the telescopic board is pulled out, it will not be pulled out completely due to excessive force. At the same time, the stability of the telescopic board is increased, and it is more firm during use.
