Description

Technical Field

[0001] This utility model relates to an assembly structure, and more specifically, to an assembly structure for the front panel of a drum dryer. Background Technology

[0002] While tumble dryers offer convenience in modern life, people are increasingly valuing their aesthetics. However, the bodies and front panels of most current mainstream products are made of sheet metal. Although sheet metal is strong, it is not aesthetically pleasing, and changing its shape requires significant costs. Therefore, cheaper and more malleable plastic is used as a substitute, allowing for more diverse appearances. However, in actual production, it has been found that plastic parts have limited strength and are prone to creep, resulting in insufficient rigidity at joints. The body and front panel are easily deformed, cracked, and even have screw holes broken. Furthermore, the rotating drum generates significant centrifugal force during drying. Although low-speed drying maximizes efficiency, it still produces considerable vibration energy. The weak plastic body structure cannot effectively suppress and absorb this vibration energy, causing the machine to shake or even shift during operation. Long-term vibration accelerates structural fatigue, shortens the machine's lifespan, and poses safety hazards. Therefore, a new front panel assembly structure for tumble dryers is needed. This structure can strengthen the connection between the front panel and the body, preventing body twisting.

[0003] For the reasons mentioned above, how to strengthen the connection between the front panel and the housing is the problem addressed in this application. Utility Model Content

[0004] To address the shortcomings of existing technologies, a front panel assembly structure for a drum dryer is provided. This structure strengthens the connection between the front panel and the housing, preventing the housing from twisting.

[0005] To achieve the above objectives, the following technical solution is provided: a front panel assembly structure for a drum dryer, including a housing, a front panel, and a fixing plate assembly. The fixing plate assembly is connected inside the front panel and is used to increase the contact area with the front panel. The housing is connected to the fixing plate assembly, which is also used to increase the contact area with the front panel.

[0006] Furthermore, the fixing plate assembly includes a boss and an additional plate. The boss is fixedly connected to the housing, and the additional plate is fixedly connected to the boss. The boss abuts against the inner wall of the front plate.

[0007] Furthermore, the outer corners of the boss and the outer corners of the mounting plate are both curved.

[0008] Furthermore, multiple connecting posts are fixedly connected to the front panel, and the connecting posts are provided with first connecting holes. Multiple second connecting holes are provided on the mounting plate, and the second connecting holes are set corresponding to the first connecting holes.

[0009] Furthermore, the connecting column is fixedly connected with a protective plate.

[0010] Furthermore, the fixed plate assembly also includes a support plate, which is fixedly connected to the boss and is used to support the front plate.

[0011] Furthermore, the fixing plate assembly also includes positioning posts, and the front plate is provided with positioning holes. The positioning posts are fixedly connected to the support plate, and the positioning holes are used to accommodate the positioning posts.

[0012] In summary, the above technical solution has the following beneficial effects: By establishing a large-area rigid connection interface in the built-in fixed plate assembly and fastening it with bolts or screws, the present invention maximizes the contact area, thereby enhancing the connection tightness, structural stability, vibration resistance and overall structural strength.

[0015] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. Identical components are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "upper," and "lower" used in the following description refer to directions in the accompanying drawings, and the terms "bottom surface," "top surface," "inner," and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0016] Reference Figure 1-5 As shown, the front panel assembly structure of the drum dryer includes a housing 1, a front panel 2, and a fixing plate assembly 3. The fixing plate assembly 3 is connected inside the front panel 2 and is used to increase the contact area with the front panel 2. The housing 1 is connected to the fixing plate assembly 3, and the fixing plate assembly 3 is used to increase the contact area with the front panel 2.

[0017] The fixing plate assembly 3 is installed on the inner side of the front plate 2. The main function of the fixing plate assembly 3 is to increase the contact area with the front plate 2 itself. The fixing plate assembly 3 is usually an integral structure extending from the front end of the box 1. It is connected to the front plate 2 by bolts or screws and other components. Therefore, the fixing plate assembly 3 can be used as a connection medium to increase the contact area between the box 1 and the front plate 2. The fixing plate assembly 3 is essentially used as a more robust mounting base inside the front plate 2. Bolts or screws no longer simply connect the thin edges of the housing 1 and the front plate 2, but pass through the extended fixing plate from the housing 1 and are tightened to the main body of the front plate 2. In this way, the tightening force applied by the bolts or screws can act between the two large-area plates. When the housing 1 is subjected to vibration or external force, these forces are no longer concentrated around a few small screw holes. The larger contact area allows the force to be effectively distributed throughout the fixing plate assembly 3 and the interior of the front plate 2. When the dryer is running, the rotation of the drum will generate significant vibration. The large contact area and the stable screw connection can effectively absorb and dampen the vibration, preventing the connection points from loosening due to long-term vibration. The fixed plate assembly 3 forms a reinforced support frame, which significantly improves the overall structural strength and rigidity of the front plate 2 mounting area, strengthens the connection strength between the front plate 2 and the housing 1, and prevents the housing 1 from twisting. In addition, the housing 1 and the fixing plate assembly 3 can adopt an integrated structure, which facilitates overall installation and control of subsequent processing technology; This invention establishes a large-area rigid connection interface in the built-in fixed plate assembly 3 and fastens it with components such as bolts or screws. By maximizing the contact area, it enhances the tightness of the connection, structural stability, vibration resistance, and overall structural strength.

[0018] Furthermore, the fixing plate assembly 3 includes a boss 31 and an mounting plate 32. The boss 31 is fixedly connected to the housing 1, and the mounting plate 32 is fixedly connected to the boss 31. The boss 31 abuts against the inner wall of the front plate 2.

[0019] The boss 31 is directly fixed to the housing 1. Its core function is to extend forward so that its outer end face abuts against the inner wall of the front panel 2. During assembly, the boss 31 abuts against the inner wall of the front panel 2 to help accurately determine the position of the front panel 2 relative to the housing 1. At the same time, it provides a direct rigid support point for the front panel 2. The force acting on the housing 1 is directly transmitted to the front panel 2 through the boss 31. The mounting plate 32 is fixedly connected to the boss 31, covering a larger area inside the front panel 2. This further increases the contact area with the inner surface of the front panel 2, dispersing the force transmitted from the boss 31 and its own supporting force to a larger area of ​​the front panel 2.

[0020] Furthermore, the outer corners of the boss 31 and the outer corners of the mounting plate 32 are both arc-shaped.

[0021] The outer corners of both the boss 31 and the mounting plate 32 are designed to be rounded, which can eliminate stress concentration, improve structural strength and fatigue life, and prevent cracking.

[0022] Furthermore, multiple connecting posts 21 are fixedly connected to the front plate 2, and the connecting posts 21 are provided with first connecting holes 22. The mounting plate 32 is provided with multiple second connecting holes 33, and the second connecting holes 33 are set corresponding to the first connecting holes 22.

[0023] Furthermore, the connecting column 21 is fixedly connected to the protective plate 23.

[0024] A connecting post 21 is provided on the front plate 2. The first connecting hole 22 on the connecting post 21 can be matched with the second connecting hole 33 on the mounting plate 32. The mounting plate 32 can be fixed to the front plate 2 using bolts or screws. Compared with the method of fixing the housing 1 directly to the thin plate of the front plate 2, the connecting post 21 provides a more robust and reliable connection point than directly drilling holes in the thin plate of the front plate 2. This avoids the problems of insufficient strength, easy deformation or tearing that may be caused by drilling holes directly in the thin-walled front plate 2. In addition, a protective plate 23 is provided on these connection points to prevent parts from directly damaging the connecting post 21 during vibration, further enhancing the strength of the overall structure. It can also be used to guide the installation of the housing 1.

[0025] Furthermore, the fixed plate assembly 3 also includes a support plate 34, which is fixedly connected to the boss 31 and is used to support the front plate 2.

[0026] Furthermore, the fixing plate assembly 3 also includes a positioning stake 35. The front plate 2 is provided with a positioning hole 24. The positioning stake 35 is fixedly connected to the support plate 34, and the positioning hole 24 is used to accommodate the positioning stake 35.

[0027] The support plate 34 is fixedly connected to the boss 31 and can support the front plate 2, preventing the front plate 2 from sagging due to its own weight or external force. The positioning stake 35 is fixedly connected to the support plate 34 and guides the installation of the front plate 2 in conjunction with the positioning hole 24 on the front plate 2. It can also serve as a reinforcing connection structure.
