Description
Technical Field
[0001] The utility model relates to a tray, in particular to a mobile tray used for a table top. Background Art
[0002] Modern home decoration usually sets up a preparation table in the kitchen or dining room to place various small kitchen appliances, such as air fryers, microwave ovens, ovens, bread machines, etc. The depth of the preparation table is generally 50~60cm. However, in order to maximize the storage space in the kitchen, the preparation table is usually designed with corresponding storage cabinets, which leads to some preparation tables being too deep, some reaching 70~90cm, or even 1m. Since small kitchen appliances are generally placed flat against the wall on the preparation table, if the depth of the preparation table is too large, it will also cause the small kitchen appliances placed on the preparation table to become troublesome when taking and placing. The small kitchen appliances need to be manually taken from the inner position of the countertop to the outer position of the countertop; for some situations where manual placement is inconvenient, the small kitchen appliances will be dragged to the edge of the countertop by direct dragging. If dragged for a long time, the countertop and the base of the small kitchen appliances will be worn. Summary of the invention
[0003] The problem to be solved by the utility model is to provide a mobile tray for a countertop, which can facilitate the movement of small kitchen appliances on a high-depth countertop. The technical solution adopted is as follows:
[0004] A mobile tray for a table top includes a tray body with movable rollers arranged underneath the tray body. The tray body also includes supporting rollers and a lifting drive mechanism, wherein the lifting drive mechanism is arranged on the lower surface of the tray body, the supporting rollers are connected to the power output end of the lifting drive mechanism, and the lifting drive mechanism can drive the supporting rollers to descend or ascend so that the tray body area corresponding to the supporting rollers can be lifted or lowered accordingly.
[0005] The mobile tray is used as a placement device for placing small kitchen appliances on a meal preparation table in daily life.
[0006] The above-mentioned lifting drive mechanism is used to lift or lower the tray area corresponding to the support roller when the support roller descends or rises: when the support roller descends to expose the lower surface and contact the countertop, as the support roller continues to descend, the corresponding position of the tray where the support roller is located will be slightly raised and leave the countertop accordingly. At this time, the bottom of the tray is supported by the moving roller and the support roller. The user can manually pull the entire moving tray to move on the countertop and manually drag the small kitchen appliance from the inner position of the countertop to the outer position of the countertop; when the desired position is reached, the lifting drive mechanism raises the support roller again, so that the corresponding position of the raised tray is lowered accordingly until it contacts the countertop, and the lower surface of the tray is partially pressed against the countertop, making it difficult to move, thereby fixing the position, which is equivalent to braking.
[0007] Since the small kitchen appliances are placed on the mobile tray, the mobile tray is moved on the countertop via the moving rollers and supporting rollers on its lower surface. There is no need to lift the small kitchen appliances, which saves a lot of effort.
[0008] As a preferred solution of the utility model, the support roller is located at the front of the tray, and the moving roller is arranged at the rear of the tray and opposite to the support roller. The support roller and the moving roller are arranged opposite to each other in front and back. When the support roller descends and the corresponding position of the tray is slightly raised, the tray uses its rear as a fulcrum to maximize the torque of the lifting drive mechanism and save the driving force of the lifting drive mechanism.
[0009] As a further preferred solution of the utility model, the tray is rectangular, the support roller is located in the middle of one side in the length direction of the tray; there are two movable rollers, which are arranged on one side in the length direction of the tray and on both sides in the width direction of the tray. The support roller and the two movable rollers form a triangular support structure to ensure the stability of the kitchen appliance on the tray, so that when the tray moves on the countertop, the kitchen appliance will not tilt on the tray.
[0010] As a preferred solution of the utility model, the lower surface of the tray is also provided with an anti-skid pad. The anti-skid pad is provided on the lower surface of the tray to increase the friction between the tray and the table when the tray is placed flat on the table, and also makes it difficult to move when the supporting roller rises and the corresponding position of the raised tray is lowered until it contacts the table.
[0011] In a specific solution, in order to ensure the stability of the raised portion of the tray when it is lowered, anti-skid pads can be provided on both sides of the supporting rollers.
[0012] As a preferred solution of the utility model, the lifting drive mechanism is a manually operated drive mechanism or an electrically operated drive mechanism. According to the requirements, the lifting drive mechanism can be manually operated or electrically driven. Manual operation can directly lower or raise the support roller by pressing or pulling. Electric operation can directly use a cylinder to drive the support roller to rise and fall, or a servo motor to drive the screw nut to drive the support roller to rise and fall, as long as the disk has enough installation space.
[0013] As a further preferred embodiment of the utility model, the manual operation drive mechanism includes a pressing block and a pressing linkage mechanism; a notch for installing the pressing block is provided on the plate body, the pressing block is arranged in the notch, and the pressing block is linked with the supporting roller through the pressing linkage mechanism. When the pressing block is pressed, the supporting roller descends to expose the lower surface of the plate body and contact the table top, and correspondingly, the corresponding position of the plate body where the supporting roller is located is slightly raised; when the pressing block is released, under the action of the gravity of the kitchen appliance itself, the supporting roller rises and recovers accordingly, and the pressing block is reset.
[0014] As a further preferred embodiment of the present invention, the pressing linkage mechanism includes a swing arm and a swing shaft, the two ends of the swing shaft are rotatably mounted on the lower surface of the disk, one end of the swing arm is fixedly connected to the swing shaft, and the other end of the swing arm is fixedly connected to the lower surface of the pressing block; the supporting roller is rotatably mounted in the middle of the swing arm. The pressing block and the supporting roller are linked by the swing arm and the swing shaft. When the pressing block is pressed, the swing arm swings down, so that the supporting roller extends downward and contacts the table, and the corresponding position of the disk where the supporting roller is located is slightly raised accordingly; when the pressing block is released, under the action of the gravity of the kitchen appliance itself, the swing arm naturally swings up, the supporting roller rises and recovers accordingly, and the pressing block is reset.
[0015] In a specific solution, the pressing block and the swing arm can be integrally formed.
[0016] As a further preferred embodiment of the present invention, the swing arm includes a horizontal section and an inclined section, the upper end of the inclined section is fixedly connected to the lower surface of the pressing block, the lower end of the inclined section is connected to one end of the horizontal section, and the other end of the horizontal section is fixedly connected to the swing shaft; the support roller is rotatably installed at the front of the horizontal section.
[0017] As a further preferred solution of the utility model, the notch is a through hole that vertically penetrates the tray body, the size of the through hole matches the pressing block, and the pressing block is arranged in the through hole. When pressing the pressing block, the user's finger can hook the through hole, thereby hooking the entire movable tray to move on the table, which is more convenient to use.
[0018] In a specific solution, the through hole is a rectangular hole, and the shape of the pressing block is correspondingly rectangular, so that multiple fingers can be conveniently hooked on the through hole side by side when pressing the pressing block, making it easier to drag the entire moving tray.
[0019] As a further preferred solution of the utility model, the through hole is arranged at the front edge of the disk body. When the through hole is arranged at the front edge of the disk body, the torque is maximum when the disk body is hooked with fingers and dragged, which is more labor-saving.
[0020] Compared with the prior art, the utility model has the following advantages:
[0021] The mobile tray for the tabletop of the utility model can drive the supporting rollers to descend or ascend through the lifting drive mechanism, so that the tray area corresponding to the supporting rollers is lifted or lowered accordingly. When the supporting rollers descend to expose the lower surface and contact the tabletop, as the supporting rollers continue to descend, the corresponding position of the tray where the supporting rollers are located will be slightly lifted and leave the tabletop accordingly. At this time, the tray is supported by the moving rollers and the supporting rollers below. The user can manually pull the entire mobile tray to move on the tabletop without lifting the small kitchen appliance, which is quite labor-saving. When the required position is reached, the lifting drive mechanism raises the supporting rollers again, so that the corresponding position of the lifted tray is lowered accordingly until it contacts the tabletop. The lower surface of the tray is partially pressed on the tabletop and is not easy to move, so the position is fixed, which is equivalent to braking. BRIEF DESCRIPTION OF THE DRAWINGS
