Detailed Implementation
[0018] The preferred embodiments of this utility model are described in detail below, and a clear and complete explanation is given in conjunction with the accompanying drawings.
[0019] Please see Figures 1-4 This utility model provides a dust cover for a ball cage, including a first protective end 100 and a second protective end 200 symmetrically arranged. The first protective end 100 and the second protective end 200 have the same structure. An arc-shaped plate 101 is fixedly arranged at the upper end of the first protective end 100. The arc-shaped plate 101 is made of rigid PVC and is inclined. The upper length of the arc-shaped plate 101 is less than the lower length of the arc-shaped plate 101. By setting the arc-shaped plate 101, the first protective end 100 is prevented from contacting the clamp when it is extended or retracted, thereby preventing the clamp from causing wear to the first protective end 100 and effectively protecting the first protective end 100, thus increasing the service life of the first protective end 100. The second protective end 200 is simultaneously installed with the same structure as the arc-shaped plate 101 to facilitate the assembly of the first protective end 100 and the second protective end 200.
[0020] The upper end of the arc-shaped plate 101 is fixedly installed with an installation end 102 for easy installation of the clamp. The installation end 102 is made of arc-shaped stainless steel. The upper end of the installation end 102 is installed with a limiting plate 103 for limiting the clamp. The limiting plate 103 is made of fan-shaped stainless steel. The second protective end 200 is simultaneously installed with the same structure as the installation end 102 and the limiting plate 103. The lower end of the first protective end 100 is provided with an arc-shaped plate 2 104, which has the same structure as the arc-shaped plate 1 101. A limiting plate 2 105 is fixedly installed at the lower end of the arc-shaped plate 2 104. An installation end 2 106 for easy installation of a clamp is fixedly installed at the lower end of the limiting plate 2 105. A limiting plate 3 107 for limiting the clamp is fixedly installed at the lower end of the installation end 2 106. The limiting plate 2 105, the installation end 2 106, and the limiting plate 3 107 are all made of stainless steel. The installation end 2 106 is arc-shaped, and the limiting plates 2 105 and 3 107 are fan-shaped stainless steel. The second protective end 200 is simultaneously equipped with the same structure as the arc-shaped plate 2 104, the limiting plate 2 105, the installation end 2 106, and the limiting plate 3 107, so as to facilitate the assembly between the first protective end 100 and the second protective end 200 to achieve the purpose of protecting the shaft.
[0021] The first protective end 100 differs from the second protective end 200 in that the inner sides of both the left and right ends of the first protective end 100 are fixedly installed with mounting blocks 113. The mounting blocks 113 have slots 114 on the side facing the second protective end 200. The upper and lower ends of the first protective end 100 are provided with through holes 110 to facilitate the delivery of glue into the slots 114.
[0022] A mounting hole 111 communicating with a through hole 110 is provided on one side of the first protective end 100. A sealing bolt 108 is installed in the mounting hole 111 above the first protective end 100, and a sealing bolt 209 is installed in the mounting hole 111 below the first protective end 100. When injecting glue into the slot 114, the sealing bolt 108 and the sealing bolt 209 are simultaneously removed. Glue is injected into the through hole 110 through the sealing bolt 108. The glue flows into the slot 114 through the through hole 110, so that the glue fills the space between the slot 114 and the block 202. When the glue overflows from the through hole 110 at the lower end of the first protective end 100, the sealing bolt 209 seals the through hole 110 at the lower end of the first protective end 100, and the sealing bolt 108 seals the through hole 110 at the upper end of the first protective end 100. After the glue dries, the first protective end 100 and the second protective end 200 can be tightly bonded together.
[0023] Mounting blocks 201 are fixedly installed on the inner sides of both ends of the second protective end 200. Mounting blocks 201 facing the first protective end 100 have a locking block 202 installed on the side for assembling the first protective end 100 and the second protective end 200 with the locking slot 114. The locking block 202 can be inserted into the locking slot 114. Mounting blocks 113, 201, and 202 are all made of rubber. When the locking block 202 is inserted into the locking slot 114, the wider end of the locking block 202 deforms to facilitate the insertion of the locking block 202 into the depth of the locking slot 114. The narrow part of the locking block 202 is at the front end of the cavity of the locking slot 114. After the locking block 202 is fully inserted into the locking slot 114, the locking block 202 resets, so that the connection between the locking block 202 and the locking slot 114 is stable and the locking block 202 is not easy to detach from the locking slot 114.
[0024] Both sides of the slot 114 are provided with a first groove 1141, a second groove 1142, a third groove 1143, and a fourth groove 1144. The spacing between the fourth grooves 1144 is greater than the spacing between the third grooves 1143, the spacing between the third grooves 1143 is greater than the spacing between the second grooves 1142, and the spacing between the second grooves 1142 is greater than the spacing between the first grooves 1141. Both sides of the locking block 202 are provided with a first protrusion 2021, a second protrusion 2022, a third protrusion 2023, and a fourth protrusion 2024. The first protrusion 2021 is engaged with the first groove 1141, the second protrusion 2022 is engaged with the second groove 1142, the third protrusion 2023 is engaged with the third groove 1143, and the fourth protrusion 2024 is engaged with the fourth groove 1144. The spacing between the groove 1144 and the fourth protrusion 2024 is greater than the spacing between the third protrusion 2023, the spacing between the third protrusion 2023 is greater than the spacing between the second protrusion 2022, and the spacing between the second protrusion 2022 is greater than the spacing between the first protrusion 2021. This makes it difficult for the card block 202 to be moved out of the card slot 114 after it is inserted into the card slot 114. After the glue is injected into the card slot 114 through the through hole 110, the glue fills the space between the card slot 114 and the card block 202. After the glue dries, the outer wall of the card block 202 and the inner wall of the card slot 114 are tightly bonded together, making the connection between the first protective end 100 and the second protective end 200 more stable. The upper and lower ends of the first protective end 100 and the second protective end 200 are fixed by clamps.
[0025] When dismantling the damaged first protective end 100 and second protective end 200, this utility model first removes the clamps at both ends of the first protective end 100. Then, the damaged first protective end 100 and second protective end 200 can be cut off. When installing the new first protective end 100 and second protective end 200, during the assembly of the first protective end 100 and second protective end 200, the locking block 202 is inserted into the locking slot 114, so that the sides of the first protective end 100 and the sides of the second protective end 200 are completely assembled together. Glue is injected into the through hole 110 at the upper end of the first protective end 100, filling the gap between the locking block 202 and the locking groove 114. Then, sealing bolt 2 109 and sealing bolt 108 are installed in sequence. Finally, the upper and lower ends of the first protective end 100 are fixed by clamps, thus completing the assembly of the first protective end 100 and the second protective end 200. When assembling and disassembling the first protective end 100 and the second protective end 200, it is not necessary to disassemble and install all the connecting parts on the shaft, making the operation convenient and saving time and effort.
[0026] Based on the above description and accompanying drawings, those skilled in the art can understand and implement this utility model. Furthermore, any non-creative modifications made to this utility model by those skilled in the art without inventive effort are still within the protection scope of this utility model.
