Description

Technical Field

[0001] The present invention belongs to the technical field related to deep groove ball bearings, and more specifically, relates to a stainless steel fastener used in smart devices. Background Art

[0002] Bearings are an important component in contemporary intelligent devices. Their main function is to support mechanical rotating bodies, reduce their friction coefficient during movement, and ensure their rotation accuracy. Rolling bearings generally consist of four parts: an outer ring, an inner ring, rolling elements, and a cage. Deep groove ball bearings are suitable for operation at high or even extremely high speeds, and are very durable and do not require frequent maintenance. This type of bearing has a low friction coefficient, a high maximum speed, and a variety of size ranges and forms. It is used in industries such as intelligent devices, precision instruments, low-noise motors, automobiles, motorcycles, and general machinery. It is the most widely used type of bearing in the machinery industry. However, deep groove ball bearings in the prior art have the following defects: In the existing technology, the inner ring or outer ring of the deep groove ball bearing may easily become loose due to the high-speed rotation during operation, thereby affecting the rotation accuracy of the mechanical rotating body in the smart device, which not only affects work efficiency but also poses a safety hazard.

[0003] In the prior art, in order to prevent the inner ring or outer ring of a deep groove ball bearing from loosening during high-speed rotation, a dust cover is usually installed on the deep groove ball bearing, and the two dust covers are used to limit the inner ring or outer ring of the deep groove ball bearing; however, the dust cover and the outer ring are usually fixed with bolts and nuts. Mechanical vibration or thermal expansion may cause the bolts to loosen, destroying the axial positioning of the bearing, causing noise and wear.

[0004] In the prior art, in order to improve the firmness between the dust cover and the outer ring of the deep groove ball bearing, fasteners are usually used to fix the dust cover and the outer ring. However, the current stainless steel fasteners cannot adjust the locking situation according to the mechanical vibration, resulting in the stainless steel fasteners being easily loosened during the mechanical vibration, thereby affecting the limiting effect of the dust cover on the inner ring or outer ring of the deep groove ball bearing.

[0005] Therefore, in view of this, the existing structure and defects are studied and improved, and a stainless steel fastener for use in smart devices is provided, in order to achieve a more practical and valuable purpose. Summary of the Invention

[0010] According to a further technical solution, a first spring is provided between the sides of the two movable blocks that are away from each other and the inside of the two grooves, and a torsion spring is provided between the outer wall of the rotating shaft and the side wall of the groove.

[0011] According to a further technical solution, a frame is fixedly provided on the upper inner side of the groove, and a slide rod is slidably provided inside the frame.

[0012] According to a further technical solution, one end of the slide rod is connected to the interior of the frame and is provided with a second spring, and the interior of the frame is connected to the interior of the first elastic airbag and is provided with a connecting channel.

[0013] According to a further technical solution, a second elastic airbag is provided on the lower inner side of the groove, the interior of the second elastic airbag is connected to the interior of the movable block by a telescopic connecting pipe, and the interior of the movable block is respectively connected to the interiors of several hollow elastic parts.

[0015] According to a further technical solution, a third spring is connected between one side of the counterweight block and the inner side of the shell, a second one-way valve is provided in communication between the inner side of the shell and the groove, and an air release valve is provided on one side of the movable block.

[0016] A further technical solution is that a plurality of arc-shaped rubber parts are provided in a circular array on the inner wall of the first mounting groove, the outer edge of the dust cover is a U-shaped structure, the first fastener and the second fastener are made of stainless steel, and the plurality of balls are located between the two retaining frames, and the two retaining frames are fixedly connected to each other.

[0017] Compared with the prior art, the present invention has the following beneficial effects: A stainless steel fastener for smart devices according to the present invention comprises a movable block and a hollow elastic member, allowing a second fastener to slide within a second mounting slot. The two movable blocks have an inclined surface on the sides thereof, and both sides of the second fastener have inclined surfaces. The sliding of the second fastener guides the two movable blocks toward each other. As the two movable blocks move away from each other, they compress two first springs, generating elastic forces. These forces act on the two movable blocks, gradually increasing the cushioning effect on the second fastener as it slides within the second mounting slot, facilitating the stable installation of the dust cover on the outer ring. Furthermore, through the arrangement of a connecting channel, a first spring, a frame, and a sliding rod, the underside of the second fastener contacts one end of the two L-shaped blocks. The movement of the second fastener compresses one end of the two L-shaped blocks, causing the two L-shaped blocks to oscillate. The oscillation of the two L-shaped blocks compresses the first elastic airbag, forcing the gas within the first elastic airbag into the two frames through the connecting channel. The gas within the frames pushes the sliding rod within the frames, causing the sliding rod to contact one end of the movable block. The movement of the slide rod propels the movable block to rotate about the center of the rotation axis. This rotation of the movable block drives the movement of the plurality of hollow elastic members, thereby gradually reducing the distance between the plurality of pairs of hollow elastic members from near the entrance of the second mounting slot toward the bottom of the second mounting slot. The plurality of hollow elastic members and the two movable blocks thereby restrict the second fastener within the second mounting slot. Finally, through the provision of a second elastic airbag and a telescopic connecting tube, the movable block rotates to squeeze the second elastic airbag, causing the gas within the second elastic airbag to enter the movable block through the telescopic connecting tube. The gas within the movable block enters the plurality of hollow elastic members, causing the pairs of hollow elastic members to expand, thereby further restricting the second fastener within the second mounting slot.

[0018] The present invention relates to a stainless steel fastener for use in smart devices. The bolt, comprising a first V-shaped elastic member, a second V-shaped elastic member, and a fixed plate, is configured such that the bolt moves to squeeze the middle portion of the first V-shaped elastic member. The ends of the second V-shaped elastic member are supported by the inner walls of the first V-shaped elastic member, respectively, and the middle portion of the second V-shaped elastic member is supported against the upper side of the fixed plate. The bolt moves to squeeze the first V-shaped elastic member, causing the ends of the first V-shaped elastic member to be deformed toward the sides by the ends of the second V-shaped elastic member, causing the ends of the first V-shaped elastic member to move away from each other. The moving away of the ends of the first V-shaped elastic member further pushes the two L-shaped blocks to swing. The swinging of the two L-shaped blocks drives the movement of several pairs of elastic protrusions, thereby utilizing the several elastic protrusions and the two L-shaped blocks to limit the first opening. This allows the second fastener to be limited internally and externally, preventing the second fastener from moving arbitrarily within the second mounting slot. And the two L-shaped blocks swing further, thereby increasing the degree of squeezing of the first elastic airbag, so that a large amount of gas in the first elastic airbag enters the two frames respectively through the connecting channel, and a large amount of gas further pushes the sliding rod to move. The movement of the sliding rod increases the degree of rotation of the movable block, which is conducive to further improving the internal and external dual limiting effect of the second fastener, and avoiding the loosening of the dust cover during mechanical vibration.

[0019] The present invention relates to a stainless steel fastener for use in intelligent devices. The fastener controls the range of back-and-forth movement of the counterweight within the housing according to the degree of mechanical vibration through the configuration of a housing, a counterweight, and a first one-way valve. When the range of back-and-forth movement of the counterweight within the housing is large, the movement of the counterweight squeezes a large amount of fluid from the housing through the second connecting telescopic tube and the first one-way valve into the second elastic airbag, thereby causing a large degree of expansion of several pairs of hollow elastic members. This allows the fastening between the first and second fasteners to be adjusted according to the degree of mechanical vibration experienced by the deep groove ball bearing, thereby preventing the dust cover from loosening and preventing the outer ring or inner ring from loosening. Furthermore, by making both the first and second fasteners from stainless steel, the firmness between the first and second fasteners is improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] Preferably, refer to the attached Figure 1 To the attached Figure 6 The inner wall of the first mounting groove 49 is provided with a plurality of arc-shaped rubber parts 15 in a circumferential array. The outer edge of the dust cover 14 is a U-shaped structure. The first fastener 16 and the second fastener 17 are made of stainless steel. A plurality of balls 13 are located between the two retaining frames 12, and the two retaining frames 12 are fixedly connected to each other.

[0038] Specific use of the present invention: When installing the two dust covers 14 on the outer ring 10, first, the staff will respectively correspond the several second fasteners 17 to the several second installation grooves 18, and make the U-shaped frame 20 correspond to the first opening 50. The staff will operate the dust cover 14 to drive the several second fasteners 17 to move, so that the second fasteners 17 slide in the second installation grooves 18, and the U-shaped frame 20 slides in the first opening 50, so as to utilize the second fasteners 17 and the second installation grooves 18 to correspond to the U-shaped frame 20 and the first opening 50, thereby guiding and positioning the dust cover 14, so that the dust cover 14 is aligned and installed on the outer ring 10.

[0039] At the same time, the second fastener 17 slides within the second mounting groove 18. Because the two movable blocks 25 approach each other on a sloped surface, and because both sides of the second fastener 17 are sloped, the sliding second fastener 17 guides and pushes the two movable blocks 25 toward each other. As the two movable blocks 25 move away from each other, they compress the two first springs 28, generating elastic force. The elastic forces generated by the two first springs 28 act on the two movable blocks 25, respectively, to facilitate the sliding of the second fastener 17 within the second mounting groove 18, gradually increasing the cushioning effect on the second fastener 17 and facilitating the stable installation of the dust cover 14 on the outer ring 10. The movement of the movable block 25 drives the slider 26, causing the two ends of the slider 26 to slide within the two slide slots 43, respectively, to facilitate the stable sliding of the movable block 25 within the groove 19.

[0040] Next, the movement of the movable block 25 drives the slider 26, causing its ends to slide through the two second openings 45 and into the two rotating shafts 44. At this point, the underside of the second fastener 17 contacts one end of the two L-shaped blocks 22. The movement of the second fastener 17 squeezes one end of the two L-shaped blocks 22, causing the two L-shaped blocks 22 to oscillate. The swinging of the two L-shaped blocks 22 squeezes the first elastic airbag 23, forcing the gas inside the first elastic airbag 23 into the two frames 35 through the connecting channel 24. The gas inside the frames 35 pushes the slide rod 36 to slide within the frames 35, causing the slide rod 36 to slide and contact one end of the movable block 25. The movement of the slide bar 36 pushes the movable block 25 to rotate about the center of the rotation axis 44. The rotation of the movable block 25 drives the plurality of hollow elastic members 27 to move, so that the distance between the plurality of pairs of hollow elastic members 27 gradually decreases from near the entrance of the second mounting groove 18 toward the bottom of the second mounting groove 18. The plurality of pairs of hollow elastic members 27 and the two movable blocks 25 thereby limit the second fastener 17 within the second mounting groove 18. The rotation of the rotating shaft 44 twists the torsion spring 46 to generate an elastic force. Under the elastic force of the torsion spring 46, the rotating shaft 44 can be rotated and reset.

[0041] At the same time, the movable block 25 rotates to squeeze the second elastic airbag 33, causing the gas in the second elastic airbag 33 to enter the movable block 25 through the telescopic connecting tube 34. The gas in the movable block 25 enters the plurality of hollow elastic members 27, causing the plurality of pairs of hollow elastic members 27 to expand, thereby improving the position limiting effect of the second fastener 17 in the second mounting groove 18.

[0042] Next, the staff member rotates the bolt 21. Through the threaded contact between the bolt 21 and the U-shaped frame 20, the bolt 21 rotates, causing one end of the bolt 21 to contact the middle of the first V-shaped elastic member 30. The bolt 21 moves to squeeze the middle of the first V-shaped elastic member 30. The two ends of the second V-shaped elastic member 32 respectively support the inner walls of the first V-shaped elastic member 30, and the middle of the second V-shaped elastic member 32 abuts the upper side of the fixed plate 31. The bolt 21 moves to squeeze the first V-shaped elastic member 30, causing the two ends of the first V-shaped elastic member 30 to be deformed toward the sides by the two ends of the second V-shaped elastic member 32, causing the two ends of the first V-shaped elastic member 30 to move away from each other. The two ends of the first V-shaped elastic member 30 move away from each other to further push the two L-shaped blocks 22 to swing. The swing of the two L-shaped blocks 22 drives the multiple pairs of elastic protrusions 29 to move, so that the multiple elastic protrusions 29 and the two L-shaped blocks 22 are used to limit the first through opening 50, thereby being able to perform a dual internal and external limiting effect on the second fastener 17, preventing the second fastener 17 from moving arbitrarily in the second mounting groove 18.

[0043] At the same time, the two L-shaped blocks 22 swing further, thereby increasing the degree of squeezing of the first elastic airbag 23, so that a large amount of gas in the first elastic airbag 23 enters the two frames 35 respectively through the connecting channel 24, and a large amount of gas further pushes the slide rod 36 to move. The movement of the slide rod 36 increases the degree of rotation of the movable block 25, which is conducive to further improving the internal and external dual limiting effect on the second fastener 17, and avoiding the loosening of the dust cover 14 during mechanical vibration.

[0044] The staff then stably installed the two dust covers 14 on the two clamping platforms 48, used several curved rubber members 15 to retain the dust covers 14 on the clamping platforms 48, and used several first fasteners 16 and second fasteners 17 to fasten the dust covers 14 to the outer ring 10. The two dust covers 14 then restrained the balls 13 located between the outer ring 10 and the inner ring 11, preventing the outer ring 10 or the inner ring 11 from loosening.

[0045] Finally, the staff installs the assembled deep groove ball bearing into the mechanical rotation part of the smart device. During operation, the smart device generates mechanical vibrations, which are transmitted to the outer ring 10, the first fastener 16, and the housing 38. The vibration of the housing 38 and the elastic force of the third spring 40 cause the counterweight 39 to move back and forth within the housing 38. The movement of the counterweight 39 squeezes the gas within the housing 38 into the second elastic airbag 33 through the second connecting telescopic tube 41 and the first one-way valve 51. The gas in the second elastic airbag 33 enters the movable block 25 through the telescopic connecting tube 34. The gas in the movable block 25 enters the multiple hollow elastic members 27, thereby increasing the degree of expansion of the multiple pairs of hollow elastic members 27. The range of the counterweight 39's back-and-forth movement within the housing 38 is controlled according to the degree of mechanical vibration. When the counterweight 39 moves back and forth within the housing 38 over a wide range, the movement of the counterweight 39 squeezes a large amount of air from the housing 38 through the second connecting telescopic tube 41 and the first one-way valve 51 into the second elastic airbag 33, causing the pairs of hollow elastic members 27 to expand significantly. This allows for adjustment of the fastening between the first fastener 16 and the second fastener 17 based on the degree of mechanical vibration experienced by the deep groove ball bearing, preventing loosening of the dust cover 14 and the outer ring 10 or inner ring 11. The second one-way valve 47 is used to replenish the air within the housing 38, allowing the air in the groove 19 to be continuously replenished into the housing 38 during the back-and-forth movement of the counterweight 39.

[0046] A stainless steel fastener for smart devices according to the present invention comprises a movable block 25 and a hollow elastic member 27, allowing a second fastener 17 to slide within a second mounting groove 18. The two movable blocks 25 have an inclined surface on the sides thereof, and both sides of the second fastener 17 have inclined surfaces. The sliding movement of the second fastener 17 guides and pushes the two movable blocks 25 in opposite directions. As the two movable blocks 25 move away from each other, they compress two first springs 28, generating elastic forces. These forces act on the two movable blocks 25, respectively, gradually increasing the cushioning effect on the second fastener 17 and facilitating the stable installation of the dust cover 14 on the outer ring 10. Furthermore, through the arrangement of the connecting channel 24, the first spring 28, the frame 35, and the slide rod 36, the lower side of the second fastener 17 contacts one end of the two L-shaped blocks 22. The movement of the second fastener 17 compresses one end of the two L-shaped blocks 22, causing the two L-shaped blocks 22 to swing. The two L-shaped blocks 22 swing, squeezing the first elastic airbag 23. This forces the gas inside the first elastic airbag 23 to flow through the connecting passage 24 into the two frames 35. The gas inside the frames 35 pushes the slide bar 36 to slide within the frames 35, causing the slide bar 36 to slide and contact one end of the movable block 25. The movement of the slide bar 36 forces the movable block 25 to rotate about the center of the rotation axis 44. This rotation of the movable block 25 drives the plurality of hollow elastic members 27 to gradually decrease the distance between the plurality of pairs of hollow elastic members 27 from near the entrance of the second mounting slot 18 toward the bottom of the second mounting slot 18. This, in turn, utilizes the plurality of hollow elastic members 27 and the two movable blocks 25 to restrain the second fastener 17 within the second mounting slot 18. Finally, through the arrangement of the second elastic airbag 33 and the telescopic connecting tube 34, the movable block 25 rotates, squeezing the second elastic airbag 33, forcing the gas inside the second elastic airbag 33 through the telescopic connecting tube 34 and into the movable block 25. The gas in the movable block 25 enters the plurality of hollow elastic members 27 , causing the plurality of pairs of hollow elastic members 27 to expand, thereby improving the limiting effect on the second fastener 17 in the second installation groove 18 .

[0047] The present invention provides a stainless steel fastener for use in smart devices. Through the arrangement of a bolt 21, a first V-shaped elastic member 30, a second V-shaped elastic member 32, and a fixing plate 31, the bolt 21 moves to squeeze the middle portion of the first V-shaped elastic member 30. The two ends of the second V-shaped elastic member 32 respectively support the inner walls of the two ends of the first V-shaped elastic member 30, and the middle portion of the second V-shaped elastic member 32 abuts against the upper side of the fixing plate 31. The bolt 21 moves to squeeze the first V-shaped elastic member 30, so that the two ends of the first V-shaped elastic member 30 are deformed to the sides by the two ends of the second V-shaped elastic member 32, so that the two ends of the first V-shaped elastic member 30 are moved away from each other. The two ends of the first V-shaped elastic member 30 move away from each other, further pushing the two L-shaped blocks 22 to swing. The swinging of the two L-shaped blocks 22 drives the movement of the multiple pairs of elastic protrusions 29, thereby utilizing the multiple elastic protrusions 29 and the two L-shaped blocks 22 to limit the first opening 50, thereby achieving a dual internal and external limit effect on the second fastener 17, preventing the second fastener 17 from moving freely within the second mounting groove 18. Furthermore, the two L-shaped blocks 22 further swing, thereby increasing the degree of compression on the first elastic airbag 23, allowing a large amount of gas within the first elastic airbag 23 to enter the two frames 35 through the connecting channel 24. This large amount of gas further pushes the slide rod 36 to move, and the movement of the slide rod 36 increases the degree of rotation of the movable block 25, which helps further improve the dual internal and external limit effect on the second fastener 17, preventing the dust cover 14 from loosening during mechanical vibration.

[0048] A stainless steel fastener for use in smart devices according to the present invention controls the range of back-and-forth movement of the counterweight 39 within the housing 38 according to the degree of mechanical vibration, through the configuration of the housing 38, the counterweight 39, and the first one-way valve 51. When the range of back-and-forth movement of the counterweight 39 within the housing 38 is large, the movement of the counterweight 39 squeezes a large amount of fluid from the housing 38 through the second connecting telescopic tube 41 and the first one-way valve 51 and into the second elastic airbag 33, thereby causing the multiple pairs of hollow elastic members 27 to expand significantly. This allows the fastening between the first fastener 16 and the second fastener 17 to be adjusted according to the degree of mechanical vibration experienced by the deep groove ball bearing, preventing loosening of the dust cover 14, the outer ring 10, or the inner ring 11. Furthermore, by making both the first fastener 16 and the second fastener 17 of stainless steel, the secure connection between the first fastener 16 and the second fastener 17 is improved.

Many modifications and variations will be apparent to those skilled in the art. The embodiments are chosen and described in order to better illustrate the principles of the invention and its practical application and to enable those skilled in the art to understand the invention and design various embodiments with various modifications as suited for specific applications.
