Description

Technical Field

[0001] This utility model relates to the technical field of food warming boards, and in particular to a food warming board. Background Technology

[0002] In winter, due to the cold weather, cooked food cools down very easily when placed on the table, affecting not only the taste but also the normal eating experience. To prevent food from cooling down after cooking, various food warming boards have appeared on the market. Cooked food is placed on the food warming board, and the board is turned on to heat the food, thus preventing it from cooling down during the meal.

[0003] Most existing food warming boards are of a fixed size, which cannot be adjusted according to the amount of food, making them impractical. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a food warming board with adjustable size, which can be adjusted according to the amount of food, thereby improving its practicality.

[0005] Technical solution

[0006] To achieve the above objectives, this utility model provides the following technical solution: a food warming board, comprising a food warming board structure and an adjustment mechanism. The food warming board structure includes a main food warming board and two sets of auxiliary food warming boards. A power cord is electrically connected to the rear end of the main food warming board. The main food warming board has a cavity inside, and openings communicating with the cavity are provided at both the left and right ends of the main food warming board. T-shaped limiting shafts are fixedly provided at both the front and rear ends of the two sets of auxiliary food warming boards. Two sets of limiting grooves that cooperate with the T-shaped limiting shafts are symmetrically provided at both the front and rear ends of the main food warming board. The two sets of auxiliary food warming boards are symmetrically slidably mounted on the main food warming board through the openings via the cooperation of the T-shaped limiting shafts and the limiting grooves. Each of the secondary warming plates has a baffle fixedly installed on its outer side. The main warming plate and the two sets of openings are equipped with heating wires that are electrically connected to the power cord. The adjustment mechanism includes a bidirectional threaded rod, which is rotatably installed on the middle of the main warming plate. A handwheel is fixedly installed at the front end of the bidirectional threaded rod. Two sets of transmission blocks are symmetrically threaded on the bidirectional threaded rod. The two sets of transmission blocks are slidably installed in the cavity. Two sets of hinge seats are symmetrically fixed on each of the two sets of transmission blocks. Each of the four sets of hinge seats is hinged with a transmission strip. The inner ends of the two sets of secondary warming plates are fixedly equipped with hinge seats on both the front and rear sides. The outer sides of the four sets of transmission strips are respectively hinged to the four sets of hinge seats.

[0007] Preferably, the main warming plate is fixedly connected to a U-shaped buffer pad at both ends.

[0008] Preferably, anti-slip rubber pads are fixedly provided at the four corners of the bottom of the main warming plate.

[0009] Preferably, the outer wall of the handwheel is provided with multiple sets of anti-slip protrusions arranged in a ring at equal intervals.

[0010] Preferably, the main warming plate has rounded edges on all four sides and the edges of the two sets of baffles.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: In use, initially the secondary heating plate is not extended, and the baffle covers the left and right ends of the main heating plate. At this time, cooked food is placed on the main heating plate, and the main heating plate and the opening are connected to the power supply through the power cord to heat the food. When there is a large amount of food, the double-sided threaded rod is rotated by the handwheel, causing the double-sided threaded rod to drive the two sets of transmission blocks away from each other. The transmission blocks then push the secondary heating plate outward through the transmission strip, causing the secondary heating plate to extend, increasing the usable size. Food can then be placed on the main heating plate and the secondary heating plate. The extension of the secondary heating plate can be limited by the cooperation of the T-shaped limiting shaft and the limiting groove, preventing the secondary heating plate from separating from the main heating plate. Thus, the size of the heating plate can be adjusted according to the amount of food, improving practicality. Attached Figure Description

Detailed Implementation

[0018] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0019] Example

[0020] Please see Figures 1-5This utility model discloses a food warming board, including a main food warming board 1 and two sets of auxiliary food warming boards 3. The main food warming board 1 is electrically connected to a power cord at its rear end. The main food warming board 1 has a cavity inside. Both the left and right ends of the main food warming board 1 have openings 2 that communicate with the cavity. Both the front and rear ends of the two sets of auxiliary food warming boards 3 are fixedly provided with T-shaped limiting shafts 11. Both the front and rear ends of the main food warming board 1 are symmetrically provided with two sets of limiting grooves 12 that cooperate with the T-shaped limiting shafts 11. The two sets of auxiliary food warming boards 3 are symmetrically slidably installed on the main food warming board 1 through the openings 2 by cooperating with the T-shaped limiting shafts 11 and the limiting grooves 12. Both the outer sides of the two sets of auxiliary food warming boards 3 are fixedly provided with baffles 4. The main food warming board 1 and the two sets of openings 2 are provided with heating wires that are electrically connected to the power cord.

[0021] The adjustment mechanism includes a bidirectional threaded rod 5, which is rotatably mounted on the middle of the main warming plate 1. A handwheel 6 is fixedly mounted at the front end of the bidirectional threaded rod 5. Two sets of transmission blocks 7 are symmetrically threaded onto the bidirectional threaded rod 5. The two sets of transmission blocks 7 are slidably mounted in the cavity. Two sets of hinge seats 8 are symmetrically fixed on each of the two sets of transmission blocks 7. Transmission plates 9 are hinged to each of the four sets of hinge seats 8. Hinge seats 10 are fixedly mounted on the front and rear sides of the inner ends of the two sets of auxiliary warming plates 3. The outer sides of the four sets of transmission plates 9 are respectively hinged to the four sets of hinge seats 10. In use, initially the auxiliary warming plates 3 are not extended, and the baffles 4 cover the left and right ends of the main warming plate 1. At this time, a plate is placed on the main warming plate 1. Place cooked food on the heating plate, connect the main heating plate 1 and opening 2 to the power supply via the power cord to heat the food. When there is a large amount of food, rotate the double-sided threaded rod 5 by handwheel 6, causing the double-sided threaded rod 5 to drive the two sets of transmission blocks 7 to move away from each other. The transmission blocks 7 then push the secondary heating plate 3 outward through the transmission strip plate 9, making the secondary heating plate 3 extend and increasing the usable size. Food can then be placed on the main heating plate 1 and the secondary heating plate 3. The extension of the secondary heating plate 3 can be limited by the cooperation of the T-shaped limiting shaft 11 and the limiting groove 12 to prevent the secondary heating plate 3 from detaching from the main heating plate 1. This allows the size of the heating plate to be adjusted according to the amount of food, improving practicality.

[0022] Both ends of the main warming plate 1 are fixedly connected with U-shaped buffer pads 13. By setting the U-shaped buffer pads 13, it is possible to prevent the baffle 4 from colliding with the main warming plate 1 when the secondary warming plate 3 is retracted into the main warming plate 1, thus playing a buffering role and making the baffle 4 cover more tightly.

[0023] Anti-slip pads 14 are fixedly provided at the four corners of the bottom of the main warming board 1; by setting the anti-slip pads 14, the slippage of the main warming board 1 on the table surface can be effectively prevented when it is placed.

[0024] The outer wall of the handwheel 6 is provided with multiple sets of anti-slip protrusions 15 at equal intervals in a ring; by setting the anti-slip protrusions 15, it is possible to avoid slipping when turning the handwheel 6.

[0025] The main heating plate 1 has rounded arcs 16 on all four sides and the edges of the two sets of baffles 4. By setting rounded arcs 16 on the edges of the main heating plate 1 and the baffles 4, the edges of the main heating plate 1 and the baffles 4 can be made smoother.

[0026] The working principle of this utility model of a food warmer is as follows: Initially, the secondary food warmer 3 is not extended, and the baffle 4 covers both ends of the main food warmer 1. Cooked food is placed on the main food warmer 1, and the main food warmer 1 and opening 2 are connected to the power supply via a power cord to heat the food. When there is a large quantity of food, the handwheel 6 rotates the bidirectional threaded rod 5, causing the bidirectional threaded rod 5 to drive the two sets of transmission blocks 7 away from each other. The transmission blocks 7 then push the secondary food warmer 3 outwards via the transmission strip 9, extending the secondary food warmer 3 and increasing its usable size. Food can then be placed on the main food warmer 1 and the secondary food warmer 3. The T-shaped limiting shaft 11 and the limiting groove 12 work together to limit the extension of the secondary food warmer 3, preventing it from detaching from the main food warmer 1. After use, the handwheel 6 rotates the bidirectional threaded rod 5 in the opposite direction, causing the bidirectional threaded rod 5 to drive the two sets of transmission blocks 7 closer together, thereby retracting the secondary food warmer 3 back into the main food warmer 1.

[0027] The food warming board of this utility model can be installed, connected, or set in a common mechanical manner, and any method that can achieve its beneficial effect can be implemented. The main food warming board and the secondary food warming board in this utility model are heated by electric heating wires, which is a common electric heating method in the prior art. This technology is already very mature, and the structure and principle of the electric heating wires are well known to those skilled in the art, so they will not be described in detail.

[0028] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
