[0001] The utility model relates to the technical field of tape installation, and more specifically, the utility model relates to a tape installation structure for an aluminum backplane frame. Background Art

[0002] When producing mobile phones, tablets, etc., the backplane frame is essential. Commonly used ones are made of aluminum or plastic. When installing an aluminum backplane frame, tape is needed to connect the back frame and the back cover to maintain stability between the back cover and the backplane frame.

[0003] When installing the tape, first stick one side of the tape on the aluminum backplane frame, then tear off the release paper on the other side, and finally cover the back cover on the tape and squeeze for a period of time to complete the installation. When installing the tape, it is necessary to manually press the tape on the aluminum backplane frame, but it is very difficult for people to press the tape on the entire backplane frame at the same time. Therefore, there is a situation of uneven pressing, and even a situation of misalignment during pressing, resulting in tape displacement. Therefore, it is necessary to develop a new type of tape installation structure for an aluminum backplane frame that can effectively solve the above problems. Summary of the Utility Model

[0004] In order to overcome the deficiencies of the prior art, the utility model provides a tape installation structure for an aluminum backplane frame.

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] As Figures 1 to 4 shown, the present utility model provides an aluminum backplane frame tape installation structure, including a sealing box 1. A sealing cavity 2 is opened at the bottom of the sealing box 1. A pressing latex 3 is fixedly connected to the bottom of the inner cavity of the sealing cavity 2. A piston plate 4 is slidably clamped inside the sealing cavity 2. A connecting rod 5 is fixedly connected to the top of the piston plate 4. A regulating valve 6 is connected inside the connecting rod 5. The top of the regulating valve 6 extends to the upper end of the connecting rod 5 and is fixedly connected to a pressing head 7; The pressing latex 3 includes two parts, a rubber film at the top and a breathable latex block at the bottom. An aluminum backplane is placed below the pressing latex 3. The top of the aluminum backplane is in contact with the bottom of the breathable latex block. The length and width dimensions of the bottom surface of the breathable latex block are both larger than the length and width dimensions of the aluminum backplane; Due to the setting of the sealing cavity 2, pressing the pressing head 7 can compress the air at the bottom through the piston plate 4, and then the entire pressing latex 3 can be extruded under the action of air pressure, so as to press the entire aluminum backplane by the pressing latex 3, thereby achieving the purpose of simultaneously pressing the tape on the entire aluminum backplane and effectively improving the tape installation effect.

[0023] Among them, a positioning frame 8 located at the top of the pressing latex 3 is fixedly installed inside the sealing cavity 2. A plurality of reset springs 9 are evenly distributed and connected to the top of the positioning frame 8. The top of the reset springs 9 is connected to the edge of the bottom of the piston plate 4. Due to the arrangement of the positioning frame 8 and the reset springs 9, under the action of the elastic force recovery of the reset springs 9, the piston plate 4 can be assisted to move upward and reset automatically, so as to repeat the above operations after replacing the aluminum backplate.

[0024] Among them, the upper end of the connecting rod 5 penetrates through the sealing box 1. The connecting rod 5 is sealingly sleeved inside the sealing box 1, and threads are also provided inside the connecting rod 5.

[0025] Among them, the rubber film at the top of the pressing latex 3 is installed inside the sealing cavity 2, and the air-permeable latex block at the bottom of the pressing latex 3 is located below the sealing box 1.

[0026] Among them, the piston plate 4 and the connecting rod 5 are an integral body. A tapered through-hole is provided at the lower end of the piston plate 4 and the connecting rod 5. The inner diameter of the lower end of the tapered through-hole is smaller than that of its upper end. The upper end of the tapered through-hole is smoothly connected to the inner cavity of the upper end of the connecting rod 5. Due to the arrangement of the tapered through-hole, it can ensure that the compressed air in the sealing cavity 2 at the bottom of the piston plate 4 can be slowly discharged, and at the same time, it is also convenient for the regulating valve 6 to adjust its flow path diameter, so as to achieve the effect of controlling the actual pressing duration.

[0027] Among them, the bottom of the tapered through-hole is communicated with the lower part of the piston plate 4. When the lower end of the regulating valve 6 moves to the lowest part of the tapered through-hole, the pressing head 7 connected to its upper end is sealingly attached to the connecting rod 5. The above arrangement can facilitate adjusting the pressing head 7 to a state of fitting on the top of the connecting rod 5 when it is in a non-working state, so as to effectively avoid the situation that dust or water vapor enters the inside of the connecting rod 5, the piston plate 4 and the sealing cavity 2.

[0028] Among them, the regulating valve 6 includes a linkage shaft 61 movably sleeved inside the connecting rod 5. The linkage shaft 61 is connected to the connecting rod 5 through threads. A regulating valve body 62 is fixedly connected to the bottom of the linkage shaft 61. A plug 63 is connected to the bottom of the regulating valve body 62. The plug 63 is smooth and tapered. The outer diameter of the lower end of the plug 63 is smaller than that of its upper end. The upper end of the plug 63 is smoothly connected to the regulating valve body 62. The outer diameter of the upper end of the plug 63 is smaller than the outer diameter of the linkage shaft 61.

[0029] Among them, a linkage rod 65 is fixedly connected to the top of the linkage shaft 61. The upper end of the linkage rod 65 extends above the connecting rod 5 and is fixedly connected to the pressing head 7. A number of through holes 64 evenly distributed are formed inside the linkage shaft 61 on the outer sides of the regulating valve body 62 and the linkage rod 65. Both the upper and lower ends of the through holes 64 are communicated with the connecting rod 5. Due to the arrangement of the plug 63, under the restriction of the piston plate 4 and the connecting rod 5, the relative positions of the regulating valve 6 and the tapered through holes in the piston plate 4 and the connecting rod 5 can be changed through the pressing head 7, thereby achieving the effect of changing the through-hole diameter size, so that the duration of squeezing the air at the bottom of the piston plate 4 when the piston plate 4 moves downward is changed, and thus the effect of changing the duration of pressing the pressing latex 3 and the aluminum backplane tape at its bottom through the compressed air at the bottom of the piston plate 4 is achieved.

[0030] The working principle and usage process of the present utility model:

[0031] After pasting the tape on the back of the aluminum backplane, buckle the aluminum backplane with the tape onto the back of devices such as mobile phones or tablets and make it face upward. Then, cover the pressing latex 3 at the bottom of the sealing box 1 on the top of the aluminum backplane through the regulating valve 6. Then, pressing the pressing head 7 can press down the piston plate 4 through the regulating valve 6 and the connecting rod 5. Furthermore, with the cooperation of the positioning frame 8, the piston plate 4 compresses the return spring 9 and the air in the inner cavity of the sealing cavity 2. Since the air can be compressed, the entire pressing latex 3 can be squeezed through the rubber on the top of the pressing latex 3, and thus the entire aluminum backplane can be pressed through the pressing latex 3 at the same time.

[0032] Since the gas can be discharged through the connecting rod 5 and the regulating valve 6 in the piston plate 4, when pressing down the piston plate 4 through the pressing head 7, while squeezing the air at the bottom of the piston plate 4, the squeezed air is also discharged through the connecting rod 5 and the regulating valve 6. After a period of time, the air at the bottom of the piston plate 4 is emptied and cannot continue to squeeze the air. At this time, the air at the bottom cannot squeeze the aluminum backplane through the pressing latex 3, and the pressing is completed.

[0033] Before pressing, adjust the pressing duration according to the tape situation to ensure that the tape is firmly pasted. That is, before pressing, rotate the pressing head 7, which can drive the regulating valve 6 to rotate. Due to the restriction of the piston plate 4 and the connecting rod 5, the linkage shaft 61 can move up and down relative to the piston plate 4 and the connecting rod 5 under the cooperation of the internal thread of the connecting rod 5, that is, the lower ends of the regulating valve body 62 and the plug 63 move up and down relative to the middle tapered through holes of the piston plate 4 and the connecting rod 5, thereby changing the flow size of the tapered through holes, so that the duration of pressing the air at the bottom of the piston plate 4 through the pressing head 7 is changed, and thus the duration of pressing the aluminum backplane tape through the pressing latex 3 is adaptively changed.
