Description

Technical Field

[0001] This utility model particularly relates to a double-row tunnel oven. Background Technology

[0002] Existing tunnel ovens have multiple baking chambers along their length, each equipped with a rack to support the workpieces to be baked. Double-row tunnel ovens typically have two racks placed side-by-side within the baking chamber; that is, fixed supports are arranged parallel to both sides of the chamber, and a connecting support is vertically positioned between the two fixed supports. Connecting plates, each matching one of the fixed supports, are fixed to the connecting support. The two ends of the rack rest on the fixed supports and the connecting plates, respectively. However, this installation method presents the following problems in use:

[0003] Because the spacing between the fixed bracket and the connecting plate is fixed, it can only be used for the installation of shelves of a specific size, which greatly limits its use. Utility Model Content

[0004] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes a double-row tunnel oven.

[0005] To solve the aforementioned technical problems, this utility model adopts the following technical solution:

[0006] A double-row tunnel oven includes an oven body with multiple baking chambers along its length. Each baking chamber has a fixed support symmetrically arranged, and a connecting support is provided between two fixed supports. An adjustment structure is provided in the connecting support, and a connecting plate is connected to the adjustment structure. A shelf is provided between the connecting plate and the fixed support.

[0025] Further, the elastic assembly comprises a T-shaped piece 71 abutting against the fixed cap 63, the connecting rod 62 is movably connected to both ends of the T-shaped piece 71, a telescopic rod 72 is connected between the T-shaped piece 71 and the bottom wall of the movable groove 61, and a spring 73 is wound on the telescopic rod 72.

[0026] Further, the connecting plate 5 is of an L-shaped structure.

[0027] The working principle of the utility model is:

[0028] Double-row tunnel oven, such as Figures 1-2 As shown, multiple baking chambers 2 are arranged along the length of the oven body 1. Each baking chamber 2 has two symmetrically arranged fixed supports 3, and a connecting support 4 is arranged between the two fixed supports 3. A shelf 30 is placed between the fixed supports 3 and the connecting support 4, meaning two shelves 30 are placed simultaneously along the width of the baking chamber 2. To accommodate the installation of shelves 30 of different sizes, this application provides a movable groove 61 on the connecting support 4. An elastic component is provided on the bottom wall of the movable groove 61, and connecting rods 62 are connected to both ends of the elastic component. Fixed posts 611 are provided on both sides of the elastic component, and sleeves 612 are slidably arranged on the fixed posts 611. One end of the sleeve 612 is connected to a connecting plate 5, and the other end is movably connected to the connecting rod 62. During installation, the shelf 30... One end of the elastic component is placed on the connecting plate 5, and the other end is placed on the fixed bracket 3. When different sizes of shelves 30 need to be matched, the fixing cap 63 is screwed on. As the fixing cap 63 is screwed into the connecting bracket 4, the upper end of the elastic component abuts against the lower end of the fixing cap 63. Therefore, the fixing cap 63 will cause the elastic component to move downward and deform. During the downward movement of the elastic component, the two connecting rods 62 will be in an open state. Since the connecting rods 62 are connected to the sleeves 612, the two sleeves 612 will move along the fixed post 611 and move away from each other. The connecting plate 5 is connected to the sleeve 612, so the connecting plate 5 will move towards the fixed bracket 3, thereby reducing the distance between the connecting plate 5 and the fixed bracket 3. Therefore, it can accommodate the installation of shelves 30 with smaller sizes. When it is necessary to accommodate the installation of shelves 30 with larger sizes, simply screw the fixing cap 63 out along the connecting bracket 4. The working principle is similar to the above, and will not be repeated here.

[0029] Based on the above technical solution, this application designs the elastic component as a T-shaped part 71 that abuts against the fixed cap 63. The connecting rod 62 is movably disposed at both ends of the T-shaped part 71. A telescopic rod 72 is provided between the bottom of the T-shaped part 71 and the movable groove 61. A spring 73 is wound around the telescopic rod 72. For example, when the fixed cap 63 is screwed into the connecting bracket 4, it pushes the T-shaped part 71 downwards and compresses the spring 73, causing the telescopic rod 72 to be in a compressed state. The two ends of the T-shaped part 71 drive the connecting rod 62 downwards. The spring 73 exerts an upward force on the T-shaped part 71, and the fixed cap 63 exerts a downward force on the T-shaped part 71, thereby keeping the connecting rod 62 in a stable state. After the above-mentioned shelf 30 is installed, the workpiece, such as a circuit board, can be placed in the baking chamber 2 for drying.

[0030] In order to adapt the double-row tunnel furnace to the installation of different sizes of the storage rack 30, the adjusting structure is arranged on the connecting support 4, the distance between the connecting plate 5 and the fixing support 3 is adjusted through the adjusting structure, so that the installation of different types of the storage rack 30 is adapted, and the application range is wider.

[0031] In the technology of the application, how the tunnel oven dries the workpiece is a conventional means in the technical field, and is not the main design concept of the application, so it will not be described here.

[0032] Although the utility model has been described in detail with reference to the above examples, it is obvious to those skilled in the art through the disclosure that various changes or modifications can be made to the utility model without departing from the principles and spirit of the utility model defined in the claims. Therefore, the detailed description of the embodiments of the disclosure is only used to explain, not to limit the utility model, and the protection range is defined by the content of the claims.
