Description

Technical Field

[0001] This utility model relates to the field of disc brush technology, specifically to a disc brush for polishing glass covers. Background Technology

[0002] Glass covers typically refer to glass panels used to protect the screens of electronic devices, commonly found in mobile phones, tablets, and so on. They not only protect the screen from scratches and impacts but also enhance the touch experience. Current methods for polishing glass covers typically involve using a disc brush, usually made of pig bristles or other animal hair, to achieve grinding, finishing, polishing, and deburring.

[0003] Typically, when polishing glass covers, a disc brush needs to be connected to the polishing equipment. However, after frequent use, the bristles at the bottom of the disc brush tend to weaken in polishing effect. When the disc brush needs to be replaced, it involves disassembling the disc brush from the polishing equipment. A quick replacement of the disc brush can improve the efficiency of polishing glass covers. Based on this, this solution provides a glass cover polishing disc brush to solve the above-mentioned problems. Utility Model Content

A snap-fit ​​block is slidably connected to the lower plate. A snap-fit ​​groove for engaging the snap-fit ​​block is provided on one side of the slot. Drive grooves are provided on both sides of the snap-fit ​​block. A drive rod fixedly connected to the upper plate is slidably connected in each drive groove. A pair of connecting rods are fixedly connected to the upper end of the upper plate. The connecting rods pass through the fixed base and extend out to be fixedly connected to a connecting plate. A housing fixedly connected to the fixed base is provided on the outside of the drive shaft. Several sets of locking components are provided inside the housing. A locking seat for engaging the locking components is fixedly connected to the connecting plate.

[0007] Preferably, the upper side of the positioning slide is provided with a storage groove formed on the fixed base, and the slot is located directly below the storage groove.

[0008] Preferably, the sliding member includes vertical rods slidably connected to both sides of the upper plate, a lower plate fixedly connected to the lower end of the vertical rods, a limit plate fixedly connected to the upper end of the vertical rods, a return spring fixedly connected between the limit plate and the upper plate, and the return spring being sleeved on the outside of the vertical rods.

[0009] Preferably, a number of fixing blocks are fixedly connected to the lower plate, and a number of sliding grooves adapted to the fixing blocks are provided on the snap-fit ​​blocks.

[0010] Preferably, the disc brush plate is set in the shape of a quarter circle, the lower end of the disc brush plate is fixedly connected with bristles, one side of the disc brush plate is fixedly connected with a positioning strip, and the other side of the disc brush plate is provided with a positioning groove that matches the positioning strip.

[0011] Preferably, the locking element includes a sliding block slidably connected within the housing, a locking spring fixedly connected to the sliding block, one end of the locking spring being fixedly connected to the inner wall of the housing, a lever fixedly connected to the upper end of the sliding block, a through groove being provided on the housing, the upper end of the lever extending out through the through groove, and a locking rod fixedly connected to the end of the sliding block near the locking seat, one end of the locking rod penetrating the housing and extending out.

[0012] Preferably, the locking seat has a locking hole, which is coaxially arranged with the extended locking rod, and their sizes and shapes are compatible.

[0013] Compared with the prior art, the present invention proposes a glass cover polishing disc brush, which has the following beneficial effects:

[0014] 1. This utility model includes a snap-fit ​​component and a locking component. By pressing the connecting plate, the connecting plate drives the snap-fit ​​component via the connecting rod, causing the snap-fit ​​component to enter the slot of the positioning slider. The snap-fit ​​block in the snap-fit ​​component inserts into the snap-fit ​​groove of the positioning slider. Subsequently, the locking component fixes the position of the connecting plate, ensuring the connection between the snap-fit ​​block and the snap-fit ​​groove, thereby fixing the positioning slider and securing the disc brush plate. The locking component, through a locking spring, drives the sliding block towards the locking seat. The sliding block then moves the locking rod, inserting it into the locking hole of the locking seat, thus allowing the locking component to lock the locking seat. A fixed connection is formed between them, thereby fixing the position of the connecting plate and ensuring the connection between the snap-fit ​​block and the snap-fit ​​groove. When it is necessary to disassemble the disc brush plate, simply push the lever to disengage the locking rod in the corresponding locking component from the locking seat, thereby releasing the position fixation of the connecting plate. Under the action of the two return springs in the sliding component, the upper plate and the lower plate move away from each other, thereby driving the drive rod to reset inside the drive groove, thus retracting the snap-fit ​​block and releasing the connection between the snap-fit ​​block and the snap-fit ​​groove. At this time, the snap-fit ​​component is released from the fixed slider, so that the disc brush plate can be pulled out from the fixed seat for easy replacement and to improve the efficiency of polishing the glass cover plate.

[0015] 2. In this utility model, four sets of disc brush plates are provided, and each set of disc brush plates is set in the shape of a quarter circle. A positioning strip is fixedly connected to one side, and a positioning groove adapted to the positioning strip is opened on the other side, so that the four sets of disc brush plates can be combined into a large disc brush. When a single set of quarter circle disc brush plates is damaged after a period of use, only the corresponding module needs to be replaced, without discarding the entire disc brush, thus reducing maintenance costs. At the same time, each set of brush plates can independently select bristles of different hardness or density to achieve differentiated grinding, so as to adapt to different grinding requirements and improve the overall adaptability.

[0016] 3. This utility model is equipped with a locking component. When the drive shaft drives the fixed seat to rotate rapidly, the centrifugal force causes the sliding block in the locking component to slide outward, further ensuring that the locking rod is stably inserted into the locking hole on the locking seat, ensuring the fixed connection between the locking component and the locking seat, thereby fixing the connecting plate. The fixed connection effect between the snap-fit ​​block in the snap-fit ​​component and the snap-fit ​​groove in the positioning slider ensures the stable connection between the disc brush plate and the fixed seat.

[0025] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0026] Reference Figure 1-6As shown, a glass cover polishing disc brush includes a fixed base 1 and a disc brush plate 2. A drive shaft 10 is fixedly connected to the fixed base 1. The disc brush plate 2 is provided with four sets. A positioning slider 3 is fixedly connected to the upper end of the disc brush plate 2. The fixed base 1 has a positioning groove 101 adapted to the positioning slider 3. The positioning slider 3 has a slot 301. A snap-fit ​​component 4 is provided inside the slot 301. The snap-fit ​​component 4 includes an upper plate 401 slidably connected to the slot 301. A movable lower plate 402 is provided on the lower side of the upper plate 401. A sliding member is provided on the upper plate 401 to cooperate with the sliding of the lower plate 402. A snap-fit ​​block 404 is slidably connected to the upper plate 401. A snap-fit ​​groove 302 for engaging the snap-fit ​​block 404 is provided on one side of the slot 301. A drive groove 405 is provided on both sides of the snap-fit ​​block 404. A drive rod 406 fixedly connected to the upper plate 401 is slidably connected in the drive groove 405. A pair of connecting rods 5 are fixedly connected to the upper end of the upper plate 401. The connecting rods 5 pass through the fixed base 1 and extend out to be fixedly connected to the connecting plate 6. A housing 7 fixedly connected to the fixed base 1 is provided on the outside of the drive shaft 10. Several sets of locking parts 8 are provided inside the housing 7. A locking seat 9 for engaging the locking parts 8 is fixedly connected to the connecting plate 6. By pressing the connecting plate 6, the connecting plate 6 drives the snap-fit ​​component 4 through the connecting rod 5, causing the snap-fit ​​component 4 to enter the slot 301 of the positioning slider 3. At this time, the lower plate 402 contacts the upper end of the disc brush plate 2. By continuing to press the connecting plate 6, the upper plate 401 moves downward, causing the lower plate 402 and the upper plate 401 to slide closer to each other through the sliding member. This causes the upper plate 401 to drive the driving rod 406 to move downward together, causing the driving rod 406 to slide in the driving groove 405. This causes the snap-fit ​​block 404 to move outward, thus inserting the snap-fit ​​block 404 into the snap-fit ​​groove 302 of the positioning slider 3. Then, the locking member 8 fixes the position of the connecting plate 6, ensuring the connection between the snap-fit ​​block 404 and the snap-fit ​​groove 302. This fixes the positioning slider 3 with the snap-fit ​​component 4, thereby fixing the disc brush plate 2.

[0027] Specifically, in this embodiment, a storage groove 102 is provided on the upper side of the positioning groove 101 and is provided on the fixed base 1, and the slot 301 is located directly below the storage groove 102.

[0028] Specifically, in this embodiment, the sliding member includes vertical rods 407 slidably connected to both sides of the upper plate 401. The lower end of the vertical rods 407 is fixedly connected to a lower plate 402, and the upper end of the vertical rods 407 is fixedly connected to a limiting plate 408. A return spring 409 is fixedly connected between the limiting plate 408 and the upper plate 401, and the return spring 409 is sleeved on the outside of the vertical rods 407. When the upper plate 401 is subjected to force and moves downward, while the lower plate 402 remains stationary, the upper plate 401 slides on the vertical rods 407, causing the upper plate 401 and the lower plate 402 to move closer to each other, further compressing the return spring 409. When the upper plate 401 is no longer subjected to force, under the action of the two return springs 409, the upper plate 401 and the lower plate 402 move away from each other, thereby driving the drive rod 406 to reset inside the drive groove 405, thereby retracting the locking block 404 and releasing the connection between the locking block 404 and the locking groove 302.

[0029] Specifically, in this embodiment, a number of fixed blocks 403 are fixedly connected to the lower plate 402, and a number of sliding grooves adapted to the fixed blocks 403 are provided on the snap-fit ​​block 404.

[0030] Specifically, in this embodiment, the disc brush plate 2 is arranged in the shape of a quarter circle. Brush bristles 201 are fixedly connected to the lower end of the disc brush plate 2. A positioning strip 202 is fixedly connected to one side of the disc brush plate 2, and a positioning groove 203 adapted to the positioning strip 202 is opened on the other side of the disc brush plate 2. Four sets of disc brush plates 2 are provided, and each set of disc brush plates 2 is arranged in the shape of a quarter circle. One side is fixedly connected to the positioning strip 202, and the other side has a positioning groove 203 adapted to the positioning strip 202. This allows the four sets of disc brush plates 2 to be combined into a large disc brush. When a single set of quarter-circle disc brush plates 2 is damaged after a period of use, only the corresponding module needs to be replaced, without discarding the entire disc brush, reducing maintenance costs. At the same time, each set of brush plates can independently select bristles of different hardness or density to achieve differentiated polishing, adapting to different polishing requirements and improving overall adaptability.

[0031] Specifically, in this embodiment, the locking member 8 includes a sliding block 801 slidably connected inside the housing 7. A locking spring 802 is fixedly connected to the sliding block 801. One end of the locking spring 802 is fixedly connected to the inner wall of the housing 7. A lever 803 is fixedly connected to the upper end of the sliding block 801. A through groove 701 is provided on the housing 7. The upper end of the lever 803 extends out through the through groove 701. A locking rod 804 is fixedly connected to one end of the sliding block 801 near the locking seat 9. One end of the locking rod 804 passes through the housing 7 and extends out. A locking hole 901 is provided on the locking seat 9. The locking hole 901 and the extended locking rod 804 are coaxially arranged and their sizes and shapes are compatible with each other. The locking component 8 is driven by the locking spring 802 to move the sliding block 801 closer to the locking seat 9. The sliding block 801 then moves the locking rod 804, inserting it into the locking hole 901 of the locking seat 9. This allows the locking component 8 to be fixed to the locking seat 9, thus fixing the position of the connecting plate 6 and ensuring the connection between the snap-fit ​​block 404 and the snap-fit ​​groove 302. Simultaneously, when the drive shaft 10 drives the fixed seat 1 to rotate rapidly, the centrifugal force causes the sliding block 801 in the locking component 8 to slide outwards, further ensuring that the locking rod 804 is stably inserted into the locking hole 901 on the locking seat 9. This ensures the fixed connection between the locking component 8 and the locking seat 9, thereby fixing the connecting plate 6 and ensuring the fixed connection between the snap-fit ​​block 404 in the snap-fit ​​component 4 and the snap-fit ​​groove 302 in the positioning slider 3. This ensures the stable connection between the disc brush plate 2 and the fixed seat 1. When it is necessary to disassemble the disc brush plate 2, simply push the lever 803 to disengage the locking rod 804 in the corresponding locking member 8 from the locking seat 9. This will release the position fixation of the connecting plate 6. Under the action of the two return springs 409 in the sliding member, the upper plate 401 and the lower plate 402 will move away from each other, thereby driving the drive rod 406 to reset inside the drive groove 405. This will retract the snap-fit ​​block 404 and release the connection between the snap-fit ​​block 404 and the snap-fit ​​groove 302. At this time, the snap-fit ​​member 4 will be released from the fixed slider 3, and the disc brush plate 2 can be pulled out from the fixed seat 1 for easy replacement.

[0032] The working principle of this utility model is as follows: By pressing the connecting plate 6, the connecting plate 6 drives the snap-fit ​​4 through the connecting rod 5, so that the snap-fit ​​4 enters the slot 301 of the positioning slider 3. At this time, the lower plate 402 contacts the upper end of the disc brush plate 2. By continuing to press the connecting plate 6, the upper plate 401 moves down, so that the lower plate 402 and the upper plate 401 slide closer to each other through the sliding member. Then, the upper plate 401 drives the driving rod 406 to move down together, so that the driving rod 406 slides in the driving groove 405, thereby causing the snap-fit ​​block 404 to move outward and insert into the snap-fit ​​groove 302 of the positioning slider 3. Then, the position of the connecting plate 6 is fixed by the locking member 8 to ensure the connection between the snap-fit ​​block 404 and the snap-fit ​​groove 302, so that the snap-fit ​​4 fixes the positioning slider 3 and realizes the fixation of the disc brush plate 2.

[0033] In this design, the locking element 8 is driven by the locking spring 802 to move the sliding block 801 closer to the locking seat 9. The sliding block 801 then moves the locking rod 804, inserting it into the locking hole 901 of the locking seat 9. This allows the locking element 8 to be fixed to the locking seat 9, thus fixing the position of the connecting plate 6 and ensuring the connection between the snap-fit ​​block 404 and the snap-fit ​​groove 302. Simultaneously, when the drive shaft 10 drives the fixed seat 1 to rotate rapidly, the centrifugal force causes the sliding block 801 in the locking element 8 to slide outwards, further ensuring that the locking rod 804 is stably inserted into the locking hole 901 on the locking seat 9. This ensures the fixed connection between the locking element 8 and the locking seat 9, the fixed position of the connecting plate 6, and the fixed connection between the snap-fit ​​block 404 in the snap-fit ​​element 4 and the snap-fit ​​groove 302 in the positioning slider 3, thereby ensuring the stable connection between the disc brush plate 2 and the fixed seat 1.

[0034] When it is necessary to disassemble the disc brush plate 2, simply push the lever 803 to disengage the locking rod 804 in the corresponding locking member 8 from the locking seat 9. This will release the position fixation of the connecting plate 6. Under the action of the two return springs 409 in the sliding member, the upper plate 401 and the lower plate 402 will move away from each other, thereby driving the drive rod 406 to reset inside the drive groove 405. This will retract the snap-fit ​​block 404 and release the connection between the snap-fit ​​block 404 and the snap-fit ​​groove 302. At this time, the snap-fit ​​member 4 will be released from the fixed slider 3, and the disc brush plate 2 can be pulled out from the fixed seat 1 for easy replacement.

[0035] Meanwhile, the present invention provides four sets of disc brush plates 2, each set of disc brush plates 2 being arranged in a quarter circle. One side of the disc brush plate 2 is fixedly connected to a positioning strip 202, while the other side of the disc brush plate 2 is provided with a positioning groove 203 that matches the positioning strip 202. This allows the four sets of disc brush plates 2 to be combined into a large disc brush. When a single quarter circle disc brush plate 2 is damaged after a period of use, it can be replaced by replacing the damaged disc brush plate 2, without discarding the entire disc brush, thus reducing maintenance costs. In addition, each set of disc brush plates 2 can independently select bristles of different hardness or density to achieve differentiated grinding, thereby adapting to different grinding requirements and improving the adaptability of the disc brush.
