Description

Technical Field

[0001] The utility model relates to the technical field of anodic oxidation, in particular to a heart-shaped fixture for anodic oxidation of a U-shaped aluminum profile frame. Background Art

[0002] Anodic oxidation is the electrochemical oxidation of metals or alloys, especially the process of forming an oxide film on aluminum and its alloys under the action of an applied current in a corresponding electrolyte and specific process conditions. Anodic oxidation can overcome the defects of the surface hardness and wear resistance of aluminum alloys, and is an indispensable part in the use of aluminum and its alloy products.

[0003] At present, most commercial display frames are made of aluminum alloy. Therefore, anodic oxidation of commercial display frames has become an important part of the production process of commercial display frames.

[0004] As Figure 1 shown, it is a U-shaped aluminum profile frame, and the cross-sections of the middle beam 1' and the two side vertical edges 2' of the profile are both in the Figure 2 shown T-shaped structure. The outer edge of the head of the T-shaped structure is the appearance surface 3' of the product, and the foot of the T-shaped structure is the inner cavity 4' of the product. When anodic oxidation treatment is carried out on the Figure 1 shown U-shaped aluminum profile frame, it is required that there are no appearance defects such as color difference and peeling film on the appearance surface. Therefore, the contact surface between the fixture and the product can only be designed in the inner cavity of the product, and the contact surface between the fixture and the product cannot be too large, which makes it difficult for the fixture with an ordinary structure to achieve the expected process effect and increases the manufacturing difficulty of the fixture. Summary of the Utility Model

[0005] The utility model aims to provide a heart-shaped fixture for anodic oxidation of a U-shaped aluminum profile frame, so as to effectively overcome the deficiencies of the previous anodic oxidation fixtures, and make the U-shaped aluminum profile frame after anodic oxidation have no appearance defects such as color difference and peeling film.

[0006] To achieve the above object, the utility model adopts the following technical solutions.

[0007] A heart-shaped fixture for anodic oxidation of a U-shaped aluminum profile frame includes an outer frame, and hooks are respectively arranged on the left and right sides at the upper end of the outer frame;

[0008] First brackets penetrating the outer frame in the front-rear direction are respectively arranged on the left and right sides at the upper end of the outer frame. A plurality of first elastic arms are sequentially distributed on the first brackets along the front-rear direction. One end of each first elastic arm is fixedly connected to the first bracket, and the other end of each first elastic arm extends obliquely upward to the outside of the outer frame and forms a first hook bent in the front-rear direction at the end;

[0009] At the lower end of the outer frame, first cross bars running through the outer frame in the front-back direction are respectively provided on the left and right sides. A plurality of first cushion blocks in an inverted heart shape are sequentially distributed on the first cross bars in the front-back direction, and the upper ends of the first cushion blocks are fixedly connected to the first cross bars.

[0010] On the left and right sides of the outer frame, the first hooks and the first cushion blocks respectively form pairs one by one, and the corresponding first hooks and first cushion blocks are centered and aligned in the vertical direction.

[0011] Preferably, both sides of the first cushion block respectively have first recessed portions that are retracted. Both sides of the first cushion block are respectively divided by the first recessed portions to form two discontinuous upper and lower arc segments.

[0012] Compared with the prior art, the present utility model has the following beneficial effects:

[0013] In the case of pressing the first elastic arm, the inner cavity at the cross beam of the U-shaped aluminum profile frame is supported by the heart-shaped first cushion block, and the inner cavity at the vertical rod of the U-shaped aluminum profile frame is hung by the first hook. Then, the U-shaped aluminum profile frame can be hung in the outer frame through the elasticity of the first elastic arm. The contact surface between the hanging tool and the product is only located in the inner cavity of the U-shaped aluminum profile frame, and the contact points are extremely small. After anodizing, the measured U-shaped aluminum profile frame has no color difference, peeling of the film and other appearance defects.

[0014] Next, the present utility model will be further described in conjunction with the accompanying drawings of the specification and the specific embodiments. BRIEF DESCRIPTION OF THE DRAWINGS

[0026]

Embodiment 1

[0027] Refer to Figures 3 to 6 As shown, in Embodiment 1, a heart-shaped hanger for anodic oxidation of a U-shaped aluminum profile frame of the present utility model includes an outer frame 1, and hooks 2 are respectively provided on the upper ends of the outer frame 1 on the left and right sides;

[0028] First brackets 3 penetrating the outer frame 1 in the front-rear direction are respectively provided on the upper ends of the outer frame 1 on the left and right sides. A plurality of first elastic arms 4 are sequentially distributed on the first brackets 3 in the front-rear direction. One end of the first elastic arm 4 is fixedly connected to the first bracket 3, and the other end of the first elastic arm 4 extends obliquely upward to the outside of the outer frame 1 and forms a first hook 5 bent in the front-rear direction at the end;

[0029] First cross bars 6 penetrating the outer frame 1 in the front-rear direction are respectively provided on the lower ends of the outer frame 1 on the left and right sides. A plurality of first cushion blocks 7 in an inverted heart shape are sequentially distributed on the first cross bars 6 in the front-rear direction. The upper ends of the first cushion blocks 7 are fixedly connected to the first cross bars 6;

[0030] On the left and right sides of the outer frame 1, the first hooks 5 and the first cushion blocks 7 are respectively paired one by one, and the corresponding first hooks 5 and first cushion blocks 7 are centered and aligned in the vertical direction.

[0031] For Figure 1 and Figure 2 the U-shaped aluminum profile frame shown, the working principle of a heart-shaped hanger for anodic oxidation of a U-shaped aluminum profile frame in Embodiment 1 is as follows.

[0032] As Figure 4 shown, in the case of pressing the first elastic arm 4, the inner cavity at the cross beam of the U-shaped aluminum profile frame 9 is supported by the heart-shaped first cushion block 7, and the inner cavity at the vertical rod of the U-shaped aluminum profile frame 9 is hooked by the first hook 5. Then, the U-shaped aluminum profile frame can be hung in the outer frame 1 through the elastic tension of the first elastic arm 4.

[0033] As Figure 5As shown in the figure, a hanging hole 21' is provided in the inner cavity at the vertical rod 2' of the U-shaped aluminum profile frame. The first hook 5 is hung on the hanging hole 21'. Therefore, the contact surface between the first hook 5 and the U-shaped aluminum profile frame is only located in the inner cavity of the U-shaped aluminum profile frame, and the contact points are extremely small.

[0034] As Figure 6 shown in the figure, the first cushion block 7 is heart-shaped, so its outer edge is arc-shaped. The outer edge of the first cushion block 7 supports in the inner cavity at the cross beam of the U-shaped aluminum profile frame. Therefore, the contact surface between the first cushion block 7 and the U-shaped aluminum profile frame is only located in the inner cavity of the U-shaped aluminum profile frame, and the contact points are extremely small.

[0035] Preferably, both sides of the first cushion block 7 respectively have first recessed portions 71 that are retracted. Both sides of the first cushion block 7 are respectively divided by the first recessed portions 71 to form two discontinuous upper and lower arc segments, and the upper and lower two arc segments further reduce the possible contact points with the inner cavity of the U-shaped aluminum profile frame.

[0036] In summary, for a U-shaped aluminum profile frame anodic oxidation heart-shaped hanger using Embodiment 1, the contact surface between the hanger and the U-shaped aluminum profile frame is only located in the inner cavity of the U-shaped aluminum profile frame, and the contact points are extremely small. After multiple tests by the applicant, it is confirmed that the present utility model greatly reduces appearance defects such as color difference and film peeling of the anodized U-shaped aluminum profile frame.

[0037]

Embodiment 2

[0038] As Figures 7 to 10 shown in the figure, in Embodiment 2, a U-shaped aluminum profile frame anodic oxidation heart-shaped hanger of the present utility model includes an outer frame 1. Hooks 2 are respectively provided on the left and right sides at the upper end of the outer frame 1;

[0039] Second cross bars 6a penetrating the outer frame 1 in the front-back direction are respectively provided on the left and right sides at the upper end of the outer frame 1. A plurality of second cushion blocks 7a in a positive heart shape are sequentially distributed on the second cross bars 6a in the front-back direction. The lower ends of the second cushion blocks 7a are fixedly connected to the second cross bars 6a;

[0040] Second brackets 3a penetrating the outer frame 1 in the front-back direction are respectively provided on the left and right sides at the lower end of the outer frame 1. A plurality of second elastic arms 4a are sequentially distributed on the second brackets 3a in the front-back direction. One end of each second elastic arm 4a is fixedly connected to the second bracket 3a, and the other end of the second elastic arm 4a extends obliquely downward to the outside of the outer frame 1 and forms a second hook 5a bent in the front-back direction at the end;

[0041] On the left and right sides of the outer frame 1, the second hooks 5a and the second cushion blocks 7a are respectively in one-to-one correspondence and paired. The corresponding second hooks 5a and second cushion blocks 7a are centered and aligned in the vertical direction.

[0042] Preferably, both sides of the second cushion block 7a are respectively provided with inwardly recessed second recessed portions 71a, and the two sides of the second cushion block 7a are respectively divided by the second recessed portions 71a to form two discontinuous upper and lower arc segments.

[0043] Compared with the first embodiment, although the second hook 5a is located below the second cushion block 7a, the second hook 5a located on the second cushion block 7a can respectively replace the first hook 5 and the first cushion block 7 in the first embodiment, so the technical effect of achieving the same working principle as that of the first embodiment can be realized, and the appearance defects such as large color difference and film peeling of the anodized U-shaped aluminum profile frame are greatly reduced.

[0044]
