Description

Technical Field

[0001] This utility model relates to an oven, and more particularly to an oven frame fixing device. Background Technology

[0002] The description in this section provides only background information related to the disclosure of this utility model and does not constitute prior art.

[0003] There is an oven with a cylindrical cavity and a rectangular feeding frame that matches the oven. The frame and the oven are connected by multiple fixing bolts on the outer edge of the frame against the inner wall of the oven. The oven is stabilized through point-to-point contact. During production, the operator needs to frequently place materials into the frame, which may inevitably cause vibration. Since the friction of point-to-point contact is relatively weak, it may cause horizontal friction and ultimately affect the baking quality of the materials.

[0004] It should be noted that the above introduction to the technical background is only for the purpose of providing a clear and complete explanation of the technical solutions of this utility model and facilitating understanding by those skilled in the art. It should not be assumed that these technical solutions are known to those skilled in the art simply because they have been described in the background section of this utility model. Utility Model Content

[0005] The purpose of this invention is to provide an oven frame fixing device. By setting an expansion ring, the friction between the oven frame fixing device and the oven is increased. Furthermore, the tightness of the expansion ring can be adjusted by fasteners to increase the contact strength between the limiting mechanism and the fixing bolts, making the frame more stable.

[0006] To achieve the above objectives, this utility model discloses an oven frame fixing device, installed in an oven, for fixing the frame in the oven; the oven frame fixing device includes:

[0007] An expansion ring is attached to and nested inside the oven. The expansion ring has an opening, and the two ends of the opening of the expansion ring are connected together by a fastener.

[0008] A fixing bolt is installed on the outer contour of the frame;

[0009] A limiting mechanism is installed on the inner ring wall of the expansion ring. The position of the limiting mechanism corresponds to the fixing bolt. When the frame is installed in the oven, one end of the limiting mechanism abuts against the fixing bolt.

[0010] The number of combinations of the fixing bolt and the limiting mechanism is not less than two, and at least one of the limiting mechanisms abuts against one of the fixing bolts in the clockwise direction of the expansion ring, and at least one of the limiting mechanisms abuts against one of the fixing bolts in the counterclockwise direction of the expansion ring.

[0011] As a further description of the above technical solution, the expansion ring is made of an elastic material, and the fastener is rotatably connected to both ends of the opening of the expansion ring, so that the size of the expansion ring can be adjusted by the rotation of the fastener, thereby changing the contact strength between the limiting mechanism and the fixing bolt.

[0012] As a further description of the above technical solution, the limiting mechanism includes a bracket and a limiting part. The bracket is fixed on the inner wall of the expansion ring, and the limiting part is detachably connected to the bracket. The end of the limiting part is used to abut against the fixing bolt.

[0013] As a further description of the above technical solution, the end of the limiting part is configured as a V-shaped opening that matches the diameter of the fixing bolt.

[0014] As a further description of the above technical solution, the frame is configured as a cuboid, and the fixing bolts are located at the edges of the cuboid.

[0015] As a further description of the above technical solution, a fixing bolt is provided on each of the four sides of the cuboid adjacent to the expansion ring.

[0016] As a further description of the above technical solution, the oven frame fixing device includes a plurality of expansion rings, which are sleeved on the outside of the frame in the same direction.

[0017] Based on the above technical solution, the beneficial effects of this utility model are as follows:

[0018] The oven frame fixing device of this utility model increases the friction between the oven frame fixing device and the oven by setting an expansion ring. Compared with the existing point-to-point design where the fixing bolts directly contact the oven, it has better stability. Furthermore, the tightness of the expansion ring can be adjusted by fasteners to increase the resistance strength of the limiting mechanism against the fixing bolts. The fixing of the frame can be flexibly corrected as needed, making the fixing more stable and easier for later adjustment and maintenance.

[0027] Please see Figure 1-2 This is an oven frame fixing device according to this embodiment, installed in the oven 100, used to fix the frame 200 in the oven 100; wherein the oven frame fixing device includes:

[0028] An expansion ring 1 is attached and nested inside the oven 100. The expansion ring 1 has an opening, and the two ends of the opening of the expansion ring are connected together by a fastener 11.

[0029] Fixing bolt 2 is installed on the outer contour of frame 200;

[0030] The limiting mechanism 3 is installed on the inner ring wall of the expansion ring 1. The position of the limiting mechanism 3 corresponds to the fixing bolt 2. When the frame 200 is installed in the oven 100, one end of the limiting mechanism 3 abuts against the fixing bolt 2.

[0031] The number of combinations of fixing bolt 2 and limiting mechanism 3 is not less than two, and at least one limiting mechanism 3 abuts against a fixing bolt 2 matched with it in the clockwise direction along the expansion ring 1, and at least one limiting mechanism 3 abuts against a fixing bolt 2 matched with it in the counterclockwise direction along the expansion ring 1.

[0032] With the above structure, during use, the operator only needs to pre-install the expansion ring 1 in the oven 100, place the material to be baked on the frame 200, and then place it in the oven 100 through the entrance. Specifically, multiple fixing bolts 2 on the outside of the frame 200 are respectively engaged with the limiting mechanisms 3 surrounding the expansion ring 1, so that each fixing bolt 2 corresponds to one limiting mechanism 3, achieving initial fixation. Then, the operator adjusts the fasteners 11 of the expansion ring 1, generally by loosening them, so that the expansion ring 1 undergoes a slight deformation under the traction of the fasteners 11, generally increasing the diameter of the expansion ring 1, and causing the multiple limiting mechanisms 3 within the expansion ring 1 to move closer to the corresponding fixing bolts 2, making the contact between the limiting mechanisms 3 and the fixing bolts 2 tighter, thus completing the complete fixation of the frame 200.

[0033] During the aforementioned usage, as the diameter of the expansion ring 1 is increased by adjusting the fastener 11, the expansion ring 1 fits more tightly against the inner wall of the oven 100, resulting in greater friction between the inner wall of the oven 100 and the outer wall of the expansion ring 1. This means the expansion ring 1 is less likely to shift relative to the oven 100. Simultaneously, multiple limiting mechanisms 3 abut tightly against the corresponding fixing bolts 2, making the frame 200 connected to the fixing bolts 2 more stably fixed relative to the limiting mechanisms 3. This indirectly makes the fixation of the frame 200 relative to the oven more stable, thus solving the problem of instability and displacement caused by insufficient friction when the frame 200 and oven 100 are only fixed point-to-point by the fixing bolts 2 in existing devices.

[0034] It is worth noting that in this embodiment, the expansion ring 1 is made of an elastic material, and the fastener 11 is rotatably connected to both ends of the opening of the expansion ring 1, so that the size of the expansion ring 1 can be adjusted by the rotation of the fastener 11, thereby changing the contact strength between the limiting mechanism 3 and the fixing bolt 2. Specifically, both ends of the opening of the expansion ring 1 have protruding bent portions, and each bent portion has a threaded hole for the fastener 1 to pass through and for threaded connection. The fastener 1 passes between the two threaded holes, and the fastener 1 can change the distance between the two threaded holes by rotation, thereby pulling the deformation of the entire expansion ring 1.

[0035] Specifically, in this embodiment, the fixing bolt 2 is fixedly connected through the bolt holes on the frame 200, which facilitates disassembly or replacement with other fixing bolts 2 of matching length.

[0036] Furthermore, the limiting mechanism 3 includes a bracket 31 and a limiting part 32. The bracket 31 is fixed to the inner wall of the expansion ring 1, and the limiting part 32 is detachably connected to the bracket 31. The end of the limiting part 32 is used to abut against the fixing bolt 2. The end of the limiting part 32 is configured with a V-shaped opening that matches the diameter of the fixing bolt 2. Specifically, in the above structure, the detachable connection between the bracket 31 and the limiting part 32 can be found in [reference needed]. Figure 1 The limiting part 32 has a waist hole. By using different fixing positions in the waist hole of the limiting part 32, the size of the limiting part 32 extending relative to the bracket 31 can be changed. Of course, the operator can also replace the limiting part 32 with different sizes and lengths, or even the end of the irregular shape, to achieve more applicable scenarios.

[0037] Furthermore, in this embodiment, the frame 200 is configured as a cuboid, and the fixing bolts 2 are located on the edges of the cuboid. One fixing bolt 2 is provided on each of the four edges of the cuboid adjacent to the expansion ring 1. The cuboid frame 200 better meets usage requirements and is easier to handle; therefore, as... Figure 2As shown, in this embodiment, a corresponding limiting mechanism 3 is provided in each of the four directions of the expansion ring 1, which matches the four corners of the frame 200 facing the expansion ring 1 respectively. In a stable fixed state, the four sets of fixing bolts 2 and the limiting mechanism 3 are tightly fastened together to achieve balanced force on the frame 200 by the oven 100.

[0038] Furthermore, the oven frame fixing device includes multiple expansion rings 1, which are sleeved on the outside of the frame 200 in the same direction. See also... Figure 1 In this embodiment, two expansion rings 1 are provided for fixing the cuboid frame 200. The two expansion rings 1 are equidistantly fitted at the front and rear ends of the frame 200 to achieve better balance in fixing the frame 200.
