Description

Technical Field

[0001] This utility model relates to the field of oven heating structure technology, specifically an oven heating plate mounting and fixing structure. Background Technology

[0002] An oven is a sealed appliance used for baking food or drying products. Ovens are categorized into household and industrial ovens. In traditional ovens, the heating plate is typically installed onto the internal structure using fasteners such as bolts. However, this method presents several problems: First, the assembly process is complex, generally requiring tools like screws and multiple bolts for tightening, resulting in a long assembly time. Furthermore, if the heating plate is damaged and needs replacement, the process is inconvenient. Therefore, this invention proposes an oven heating plate mounting and fixing structure to solve the aforementioned problems. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides an oven heating plate mounting and fixing structure, which solves the problems mentioned in the background section.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an oven heating plate mounting and fixing structure, comprising an oven liner and a housing disposed outside the oven liner, wherein a door is hinged to the front of the housing, a heating plate is disposed above the oven liner, a groove for accommodating the heating plate is disposed above the oven liner, and a bidirectional pressing mechanism for synchronously pressing the top two sides of the heating plate is disposed above the oven liner.

[0005] Preferably, both sides of the inner wall of the casing are provided with mounting rails, and both sides of the oven liner are provided with guide grooves that are compatible with the mounting rails.

[0006] Preferably, the bidirectional pressing mechanism includes fixed blocks on both sides above the oven liner, with a rotating shaft running through each of the two fixed blocks. Two symmetrically arranged rotating blocks are fixed to the surfaces of the two rotating shafts respectively. An extension block is fixed below each of the two rotating blocks, and a pressing body is fixed to the end of the extension block. A torsion spring is sleeved on the surface of the rotating shaft, and a drive mechanism for controlling the relative rotation of the two rotating blocks is provided above the oven liner.

[0007] Preferably, the press-fit body adopts a spherical design.

[0008] Preferably, one end of the torsion spring is fixed to the surface of the rotating shaft, and the other end is fixed to the front of the fixing block.

[0009] Preferably, the driving mechanism includes a sliding plate slidably mounted above the oven liner, and two pressing blocks that cooperate with corresponding rotating blocks are slidably mounted on both sides above the oven liner. Both pressing blocks are fixed to the sliding plate via connecting rods. A support block is also fixed above the oven liner, and a screw is threaded through the support block. One end of the screw is rotatably connected to the sliding plate, and the other end of the screw is fixed to a rotating disk.

[0010] Beneficial effects

[0011] This utility model provides a mounting and fixing structure for an oven heating plate. Compared with the prior art, it has the following advantages:

[0012] The oven's heating plate mounting structure allows for easy disassembly. Rotating the rotating disc moves the entire sliding plate forward via a screw, which in turn pulls two pressing blocks forward synchronously via two connecting rods. This causes the two pressing blocks to release their pressure on the two rotating blocks, which, under the action of torsion springs, rotate, detaching the two pressing bodies from the heating plate. The heating plate is then removed from its corresponding groove. For assembly, simply reverse the rotation of the rotating disc. This design replaces multiple bolts for tightening and eliminates the need for individual screwdriver tightening. Assembly time is short, and the operation is more convenient when the heating plate needs replacement due to damage. Attached Figure Description

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1-4 The present invention provides the following technical solution: an oven heating plate mounting and fixing structure, including an oven liner 1 and a housing 2 disposed outside the oven liner 1, a door 3 hinged to the front of the housing 2, a heating plate 4 disposed above the oven liner 1, a groove 5 for accommodating the heating plate 4 disposed above the oven liner 1, and a bidirectional pressing mechanism 6 for synchronously pressing the top two sides of the heating plate 4 disposed above the oven liner 1.

[0020] Both sides of the inner wall of the casing 2 are provided with mounting guide rails 7, and both sides of the oven liner 1 are provided with guide grooves 8 that are compatible with the mounting guide rails 7. By cooperating with the mounting guide rails 7 and the guide grooves 8, the entire oven liner 1 can be assembled into the casing 2. The oven liner 1 can be positioned by the friction between the mounting guide rails 7 and the guide grooves 8.

[0021] The bidirectional pressing mechanism 6 includes fixed blocks 61 on both sides above the oven liner 1. A rotating shaft 62 is rotatably driven through each of the two fixed blocks 61. Two symmetrically arranged rotating blocks 63 are fixed to the surfaces of the two rotating shafts 62. An extension block 64 is fixed below each of the two rotating blocks 63. A pressing body 65 is fixed to the end of each extension block 64. A torsion spring 66 is sleeved on the surface of the rotating shaft 62. A drive mechanism 67 is located above the oven liner 1 to control the relative rotation of the two rotating blocks 63. The pressing body 65 has a spherical design. This spherical design prevents the tip of the extension block 64 from directly contacting the heating plate 4 when the pressing body 65 presses against it, thus protecting the heating plate 4 to some extent. One end of the torsion spring 66 is fixed to the surface of the rotating shaft 62, and the other end is fixed to the front of the fixed block 61. The design of the torsion spring 66 facilitates the quick reset of the rotating shaft 62.

[0022] The drive mechanism 67 includes a slide plate 671 slidably mounted above the oven liner 1. The slide plate 671 can slide back and forth above the oven liner 1. On both sides above the oven liner 1, pressing blocks 672 that cooperate with the corresponding rotating blocks 63 are slidably mounted. The pressing blocks 672 are triangular in shape. The pressing blocks 672 can press the rotating blocks 63, thereby controlling the pressing body 65 to rotate and press down, so as to simultaneously press the top two sides of the heating plate 4. Both pressing blocks 672 are fixed to the slide plate 671 through the connecting rod 673. A support block 674 is also fixed above the oven liner 1. A screw 675 is threaded through the support block 674. One end of the screw 675 is rotatably connected to the slide plate 671, and the other end of the screw 675 is fixed to a rotating disk 676. The rotating disk 676 can easily drive the screw 675 to rotate, thereby controlling the movement of the slide plate 671.

[0023] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0024] When the heating plate 4 needs to be disassembled, rotate the rotating disk 676, which in turn drives the entire slide plate 671 forward via the screw 675. This, in turn, pulls the two pressing blocks 672 forward synchronously via the two connecting rods 673, causing the two pressing blocks 672 to lose their pressure on the two rotating blocks 63. Under the action of the torsion spring 66, the two rotating blocks 63 rotate, causing the two pressing bodies 66 to detach from the heating plate 4. Then, the heating plate 4 can be removed from the corresponding groove 5. When the heating plate 4 needs to be assembled, place the heating plate 4 into the groove 5, and then rotate the rotating disk 676 in the opposite direction to make the two pressing blocks 672 move backward synchronously, pressing the two rotating blocks 63 respectively. This causes the two pressing bodies 66 to press the top two sides of the heating plate 4 respectively, thus achieving the pressing and fixing of the heating plate 4.
