Description

Technical field:

[0001] The utility model relates to the technical field of hardware processing equipment, and more specifically to a hanger for anodizing a rear cover of a display housing. Background technology:

[0002] The existing display housing is generally made of metal materials such as aluminum alloy housing, and the housing generally includes a housing and a rear cover installed at the rear, and the rear cover needs to be anodized;

[0003] The existing method is to process a hanging hole on the back cover, and then hang the hook in the hanging hole and hang the back cover on the frame. However, the existing setting of the hook and the hanging hole will shake when being carried and placed in the electrolyte, causing partial contact or close contact between the back cover and the hook or the frame or between the back cover and the back cover. At this time, during anodizing, no oxide film will be generated at the contact point (it is non-oxidized), and this contact part is generally on the wall surface of the back cover, resulting in non-oxidized points, which affects the overall processing effect and the quality of the back cover. Utility model content:

[0004] The utility model aims to overcome the deficiencies of the prior art and provides a hanger for anodizing the back cover of a display housing, which can fix the back cover of the display housing to a main frame without shaking. At the same time, the hanger is connected to a plate body at a waist-shaped groove of the back cover of the display housing through fixing bolts for anodizing, so that the back cover of the display housing, except for a portion where a wall plate at the waist-shaped groove is connected to the fixing bolts, can be anodized as a whole, and the wall plate at the waist-shaped groove is finally cut off, thereby ensuring the anodizing effect of the back cover of the display housing.

[0016] Figure 5 It is a schematic diagram of the partial structure of the rear cover of the display housing. Specific implementation method:

[0017] For example, see Figures 1 to 5 As shown, a hanger for anodizing the back cover of a display housing includes a main frame 10, which is a titanium alloy frame with good conductivity and acid and corrosion resistance. The main frame 10 includes a front rectangular frame 14 and a rear rectangular frame 15 corresponding to each other. The two ends of the transverse beam 11 are welded and fixed to the opposite wall surfaces in the middle of the upper beams of the front rectangular frame 14 and the rear rectangular frame 15, and the front and rear ends of the bottom beam 16 are welded and fixed to the opposite wall surfaces in the middle of the lower beams of the front rectangular frame 14 and the rear rectangular frame 15. A first beam 9 is provided between the left parts of the upper beams of the front rectangular frame 14 and the rear rectangular frame 15, and the two ends of the first beam 9 are welded and fixed to the opposite wall surfaces of the upper beams of the front rectangular frame 14 and the rear rectangular frame 15.

[0018] A plurality of vertical support rods 12 are welded and fixed to the side wall of the transverse beam 11, and two mounting through holes are formed at the lower part of the vertical support rod 12. Elastic sheets 13 are welded and fixed on the front wall surface above the mounting through hole at the upper part and below the mounting through hole at the lower part of the vertical support rod 12, and the two elastic sheets 13 are formed with elastic pressing parts 131 extending obliquely forward at the close ends thereof, and arc-shaped bending parts 132 are formed at the ends of the elastic pressing parts 131. The rear cover plate 100 of the display housing to be processed is located in front of the corresponding vertical support rod 12, and a waist-shaped groove 101 is formed on the front wall surface of the middle part of the rear cover plate 100 of the display housing, and the upper part of the wall plate at the rear wall surface of the waist-shaped groove 101 is formed. A snap hole 102 is formed on the upper and lower parts, and an aluminum block 1 is pressed against the rear wall of the wall panel at the rear wall of the waist-shaped groove 101. The front end of the arc-shaped bending part 132 is elastically pressed against the upper or lower part of the rear wall of the corresponding aluminum block 1. The screw parts of the two fixing bolts 2 are inserted into the corresponding snap holes 102, the corresponding through holes on the aluminum block 1 and the corresponding upper mounting through holes or lower mounting through holes. The rear end of the screw part of the fixing bolt 2 extends out of the rear wall of the corresponding vertical support rod 12 and is screwed with a locking nut 3. The front end face of the locking nut 3 is pressed against the rear wall of the corresponding vertical support rod 12, and the rear wall of the rotating part of the fixing bolt 2 is pressed against the rear wall of the waist-shaped groove 101.

[0019] Furthermore, the top and rear of the wall panel at the rear wall of the waist-shaped groove 101 are bent backwards, and the arc-shaped top and bottom surfaces of the wall panel at the rear wall of the waist-shaped groove 101 are separated from the top and bottom surfaces of the waist-shaped groove 101. This structure enables the top and bottom arc surfaces of the waist-shaped through groove formed after the wall panel at the rear wall of the waist-shaped groove 101 is washed out during the later anodizing, and no oxidation leakage points are generated. Similarly, the thickness of the wall panel at the rear wall of the waist-shaped groove 101 is about 0.1 mm. In this way, after being washed out in the later period, the area of ​​the left and right side walls in the middle of the waist-shaped through groove at the connection with the original wall panel that has not been anodized is very small and basically cannot be seen, thereby ensuring the overall anodizing effect of the back cover 100 of the display housing.

[0020] Furthermore, the snap hole 102 includes a circular through hole, and a vertical extension hole portion 103 extending vertically upward is formed on the top surface of the circular through hole. The distance between the left and right inner walls of the vertical extension hole portion 103 is smaller than the diameter of the circular through hole. The screw portion of the fixing bolt 2 is inserted into the corresponding vertical extension hole portion 103, and the minimum width of the rotating portion of the fixing bolt 2 is greater than the distance between the left and right inner walls of the vertical extension hole portion 103.

[0021] Furthermore, a middle beam extending left and right is fixed to the middle of the front rectangular frame 14 and the rear rectangular frame 15, and the left and right ends of the middle beam are welded and fixed to the inner side walls of the left and right vertical rods of the front rectangular frame 14 or the rear rectangular frame 15;

[0022] A vertically extending hook fixing rod 17 is welded and fixed in the middle of the outer wall of the middle beam. The upper end of the hook fixing rod 17 is higher than the top surface of the front rectangular frame 14 and the rear rectangular frame 15. The upper end of the hook fixing rod 17 is formed with a bent hook portion 171 extending leftward.

[0023] Furthermore, an elastic clamping plate 172 extending obliquely to the right is formed on the inner wall surface of the bottom end of the hook portion 171. The elastic clamping plate 172 allows the hook portion 171 to be hung on the hanging beam, and the hanging beam can be pressed against by the end of the elastic clamping plate 172 to improve the fixing effect.

[0024] When the present embodiment is in use, the screw portion of the fixing bolt 2 is first inserted into the circular through hole, and then lifted upward so as to be located on the vertically extending hole portion 103, and then fixed by the locking nut 3. The connection and fixation are convenient and firm, so that the rear cover plate 100 of the display housing will not shake. Then, anodizing is performed, and the processing effect is good. After completion, the main frame body 10 is removed from the hanging beam;

[0025] Then, it is only necessary to press the rear cover plate 100 of the display housing backwards to compress the arc-shaped bent portion 132, and then lift it up so that the locking nut 3 is in the corresponding circular through hole (whose inner diameter is larger than the rotating portion of the fixing bolt 2). At this time, through the restoring force of the arc-shaped bent portion 132 and the elastic force of its front end on the corresponding aluminum block 1, the aluminum block 1 is moved forward and the rear cover plate 100 of the display housing is pushed out to realize unloading. The unloading is fast and the effect is good.

[0026] Then, insert the two circular through holes of the display housing back cover 100 that needs to be processed later into the rotating parts of the corresponding two fixing bolts 2, and then move backward to compress the arc-shaped bending part 132, and the aluminum block 1 retreats, and the two rotating parts extend out of the front ends of the corresponding circular through holes. Then, move the display housing back cover 100 downward to insert the screw rod part of the fixing bolt 2 into the corresponding vertical extension hole part 103, and then let go. The aluminum block 1 is moved forward by the elastic restoring force of the arc-shaped bending part 132, and the display housing back cover 100 is clamped and fixed, and anodizing processing can be performed. It is easy to load and unload and has a good use effect.

[0027] Among them, the rear cover plate 100 of the display housing removed after the anodizing is completed can be punched out by the punching equipment to punch out the wall plate at the rear wall surface of the waist-shaped groove 101 to complete the processing of the entire component. Since the thickness of the wall plate at the rear wall surface of the waist-shaped groove 101 is about 0.1mm, after being punched out in the later stage, the area of ​​the wall surface at the connection between the left and right side walls in the middle of the waist-shaped through groove and the original wall plate that has not been anodized is very small and basically cannot be seen, thereby ensuring the oxygen rate, that is, basically ensuring the oxidation effect of the entire display housing rear cover plate 100, and in the later stage, a connecting block with a sealing effect will be clamped and installed at this waist-shaped through groove to cover the waist-shaped through groove, therefore, the part of the wall surface at the connection between the left and right side walls in the middle of the waist-shaped through groove and the original wall plate that has not been anodized is also covered, and the unoxidized part here does not affect its quality, and the rest of the rear cover plate 100 of the display housing has no oxidation-free points, thereby ensuring the overall anodizing effect and improving the processing quality of the product.

[0028] The above implementation modes are only used to illustrate the present invention, but not to limit the present invention. Ordinary technicians in the relevant technical field can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, all equivalent technical solutions also belong to the scope of the present invention. The scope of patent protection of the present invention should be limited by the claims.
