Description

Technical Field

[0001] This utility model relates to an assembly structure, and more specifically, to an assembly structure for the back 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 back 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 back 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 back panel assembly structure for tumble dryers is needed. This structure can strengthen the connection between the back panel and the body, preventing body twisting.

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

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

[0005] To achieve the above objectives, the following technical solution is provided: a rear panel assembly structure for a drum dryer, including a housing, a rear panel, and a connecting bracket assembly. The connecting bracket assembly is connected to the housing and is used to increase the contact area with the housing. The rear panel is connected to the connecting bracket assembly, and the connecting bracket assembly is used to increase the contact area with the rear panel.

[0006] Furthermore, the connecting bracket assembly includes an upper connecting bracket and a side connecting bracket, which are detachably connected. Both the upper connecting bracket and the side connecting bracket abut against the inner wall of the housing, and both the upper connecting bracket and the side connecting bracket are fixedly connected to the rear plate.

[0007] Furthermore, both the upper connecting frame and the side connecting frame are provided with multiple connecting posts, and the rear plate is provided with multiple second connecting holes, which are set corresponding to the connecting posts.

[0008] Furthermore, the housing is fixedly connected with multiple connecting seats, and the upper connecting frame and the side connecting frame are each provided with multiple connecting slots, which are used to accommodate the connecting seats.

[0009] Furthermore, the connector is in the shape of a triangular prism, and a first connecting hole is provided on the connector.

[0010] Furthermore, both ends of the upper connecting frame are provided with fitting grooves, and the side connecting frame is provided with fitting parts. The fitting grooves are used to accommodate the fitting parts.

[0011] Furthermore, both ends of the upper connecting frame are curved.

[0012] Furthermore, the side connecting frame is L-shaped, and the corner nodes are set in an arc shape.

[0013] Furthermore, the connecting bracket assembly is U-shaped.

[0014] Furthermore, the upper connecting frame and the side connecting frame form a U-shape after being connected.

[0015] In summary, the above technical solution has the following beneficial effects: This utility model uses a connecting bracket assembly with a specific width and thickness as an intermediate connector. Its width is mainly used to increase the contact area with the back panel and provide a wide support surface. Its thickness is mainly used to increase the contact area with the inner surface of the box and provide a deep joint surface. At the same time, the design of increasing the contact area can effectively disperse stress, increase friction and improve overall rigidity, thereby improving the stability of the connection between the box and the back panel and the overall structural strength.

[0022] 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.

[0023] Reference Figure 1-5 As shown, the rear panel assembly structure of the drum dryer includes a housing 1, a rear panel 2, and a connecting bracket assembly 3. The connecting bracket assembly 3 is connected inside the housing 1 and is used to increase the contact area with the housing 1. The rear panel 2 is connected to the connecting bracket assembly 3, and the connecting bracket assembly 3 is used to increase the contact area with the rear panel 2.

[0024] The connecting bracket assembly 3 is a rigid component with a certain width and thickness. The connecting bracket assembly 3 is connected and fixed to the inner surface of the housing 1, and the rear plate 2 is connected and fixed to the connecting bracket assembly 3. The connecting bracket assembly 3 has a large width, which significantly increases the actual contact area between the fixing frame and the rear plate 2. The connecting bracket assembly 3 has a large thickness, which significantly increases the actual contact area between the fixing frame and the inner surface of the housing 1. Through this connecting bracket assembly 3, the rear plate 2 is indirectly connected to the housing 1 through a connection point with a greatly increased contact area. The contact area is one of the key factors that determine the strength and stability of the connection. In this utility model, the force transmitted between the housing 1 and the back plate 2 is distributed to a larger surface, avoiding stress concentration on a few points or a small area. When using bolts or other fasteners for locking, the larger contact area generates greater friction, resisting relative sliding or loosening between components. The back plate 2 obtains a more uniform and wider support base, reducing the risk of local deformation or warping. The width of the fixing frame directly increases the support surface of the back plate 2, while the thickness increases its contact surface with the inner wall of the housing 1. The two work together to maximize the effective connection area in both the planar and longitudinal directions. When the dryer is running, the rotation of the drum will generate significant vibration. The increased contact area and the more stable connection can more effectively absorb and dampen these vibrations, prevent the vibration energy from being excessively transmitted to other parts of the housing 1 or the back panel 2, reduce abnormal noise and shaking, reduce the relative displacement or deformation of the parts under stress, and improve the overall rigidity of the equipment. This can strengthen the connection between the back panel 2 and the housing 1 and prevent the housing 1 from twisting. This utility model utilizes a connecting bracket assembly 3 with a specific width and thickness as an intermediate connector. Its width is mainly used to increase the contact area with the back plate 2, providing a wide support surface. Its thickness is mainly used to increase the contact area with the inner surface of the housing 1, providing a deep joint surface. At the same time, the design of increasing the contact area can effectively disperse stress, increase friction, and improve overall rigidity, thereby improving the connection stability between the housing 1 and the back plate 2 and the overall structural strength.

[0025] Furthermore, the connecting bracket assembly 3 includes an upper connecting bracket 31 and a side connecting bracket 32. The upper connecting bracket 31 and the side connecting bracket 32 ​​are detachably connected. Both the upper connecting bracket 31 and the side connecting bracket 32 ​​abut against the inner wall of the housing 1 and are fixedly connected to the rear plate 2.

[0026] The connecting bracket assembly 3 consists of an upper connecting frame 31 and a side connecting frame 32. The two are detachably connected together to form a more flexible and easier-to-install support frame. This frame is also tightly abutted against the inner wall of the housing 1, which significantly increases the contact area between the entire connecting bracket assembly 3 and the inner surface of the housing 1, thereby transmitting the support force provided by the housing 1 more evenly to the entire frame and facilitating maintenance and replacement.

[0027] Furthermore, both the upper connecting frame 31 and the side connecting frame 32 are provided with multiple connecting posts 33, and the rear plate 2 is provided with multiple second connecting holes 21, which are set corresponding to the connecting posts 33.

[0028] Multiple connecting posts 33 are provided on the transverse and side connecting brackets 32, and a second connecting hole 21 is provided on the corresponding position on the rear plate 2. During assembly, the connecting holes on the rear plate 2 are aligned with the connecting posts 33 on the fixing bracket, and then connecting parts such as bolts or nails can be used for connection. This multi-point fixing method greatly increases the number of contact points and connection strength between the rear plate 2 and the connecting bracket assembly 3, making the force on the rear plate 2 more uniform and less prone to deformation or loosening.

[0029] Furthermore, the housing 1 is fixedly connected with multiple connecting seats 11, and the upper connecting frame 31 and the side connecting frame 32 are each provided with multiple connecting slots 34, which are used to accommodate the connecting seats 11.

[0030] Multiple connecting seats 11 are pre-fixed on the inner wall of the housing 1. Corresponding connecting grooves 34 are designed on the transverse and side connecting frames 32. During assembly, the connecting grooves 34 on the connecting bracket assembly 3 fit into or lock the connecting seats 11 on the housing 1. The cooperation between the connecting grooves 34 and the connecting seats 11 enables the connecting bracket assembly 3 to be precisely aligned and initially fixed with the housing 1 in multiple positions. This not only increases the connection area between the fixing frame and the housing 1, but more importantly, it provides strong resistance to shear and torsion, preventing the fixing frame from shifting or rotating relative to the housing 1.

[0031] Furthermore, the connecting seat 11 is in the shape of a triangular prism, and the connecting seat 11 is also provided with a first connecting hole 12.

[0032] The triangular prism-shaped connecting seat 11 provides a stable anchor point on the inner wall of the housing 1, which can effectively prevent rotation and ensure precise alignment. The first connecting hole 12 on the connecting seat 11 is used to finally screw in bolts or screws to lock the upper connecting frame 31 and the side connecting frame 32 onto the connecting seat 11, thereby completing an extremely strong and reliable connection between the fixing frame and the housing 1.

[0033] Furthermore, both ends of the upper connecting frame 31 are provided with fitting grooves 35, and the side connecting frame 32 is provided with fitting parts 36. The fitting grooves 35 are used to accommodate the fitting parts 36.

[0034] Furthermore, both ends of the upper connecting frame 31 are arc-shaped.

[0035] Furthermore, the side connecting frame 32 is L-shaped, and the corner nodes are set in an arc shape.

[0036] The fitting 36 of the side connecting frame 32 is inserted into the fitting groove 35 at both ends of the upper connecting frame 31. If necessary, the strength of the fitting structure can be further strengthened by bolts or screws, which can form a physical interlock, simplify the assembly process, resist lateral shear force, and counteract displacement caused by vibration. The arc shape at both ends of the upper connecting frame 31 can match the common inner wall curved surface contour of the box 1, and can also increase the contact area. The arc shape of the L-shaped corner node can eliminate right angle stress concentration points, disperse vibration load, and prevent metal fatigue fracture. In addition, the mold structure of the independent upper connecting frame 31 and side connecting frame 32 is simpler during molding, and the mold cost and structure are more advantageous. The controllability and stability of the process are stronger than the one-piece molding process.

[0037] Furthermore, the connecting bracket assembly 3 is U-shaped.

[0038] Furthermore, the upper connecting frame 31 and the side connecting frame 32 form a U-shape after being connected.

[0039] The upper connecting frame 31 and the side connecting frame 32 are combined into a U-shape to form a three-way support. The upper connecting frame 31 resists the left and right torsional force of the rear plate 2, and the two side connecting frames 32 resist the up and down vibration impact, thereby evenly transferring the load of the rear plate 2 to the housing 1 and avoiding local deformation.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
