[0028] The present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for purposes of illustration and description and are not intended to be exhaustive or to limit the invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments are chosen and described 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 suitable for specific applications.

[0029] The first embodiment, as Figures 1-4 As shown, the present invention provides a technical solution: an adjustable bearing seat, comprising a base plate 1, wherein the corners of the upper surface of the base plate 1 are fixedly connected with support rods 2, and the ends of the support rods 2 are fixedly connected with track rods 3. By arranging the support rods 2, the track rods 3 can be supported on the upper surface of the base plate 1, and by arranging the track rods 3, the lateral adjustment mechanism 4 can be limited, so that the lateral adjustment mechanism 4 can produce a lateral movement effect on the outer surface of the track rod 3, and the outer surface of the track rod 3 is slidably connected with the lateral adjustment mechanism 4. By arranging the lateral adjustment mechanism 4, the lateral position of the placement mechanism 5 can be adjusted, and after the adjustment, the placement mechanism 5 can be prevented from moving. The lateral adjustment mechanism 4 includes a sliding ring 41. The sliding ring 41 is slidably connected to the outer surface of the track rod 3. The outer surface of the sliding ring 41 is fixedly connected to a fixing frame 42. By providing the sliding ring 41, the fixing frame 42 can produce a stable lateral sliding effect on the outer surface of the track rod 3. The fixing frame 42 is fixedly connected to a placement mechanism 5 on a side away from the track rod 3. The placement mechanism 5 includes a bottom frame 51. The bottom frame 51 is fixedly connected to a side of the fixing frame 42 away from the track rod 3. By providing the placement mechanism 5, the bearing can be placed and can produce stable rotation in the inner cavity of the bottom frame 51, thereby reducing the friction of the bearing when working, thereby achieving the effect of extending the service life of the bearing. By providing the bottom frame 51, the bearing can be placed;

[0030] The outer surface of the bottom frame 51 is fixedly connected to a locking mechanism 6, and directly above the bottom frame 51 is fixedly connected to a wrapping mechanism 7, and the wrapping mechanism 7 includes a top frame 71, and the top frame 71 is located directly above the bottom frame 51. By setting the locking mechanism 6, the bearings placed in the inner cavity of the bottom frame 51 can be wrapped and clamped, so that the bearings can be limited between the bottom frame 51 and the top frame 71, thereby wrapping the bearings.

[0031] The lateral adjustment mechanism 4 also includes a first threaded rod 43, the outer surface of the first threaded rod 43 is threadedly connected to a first threaded ring 44, and by setting the first threaded rod 43, the first threaded ring 44 can be limited, so that when the first threaded ring 44 rotates, it can drive the blocking rod 45 to move laterally in the inner cavity of the first threaded rod 43. The first threaded ring 44 is fixedly connected to a blocking rod 45 on the side close to the sliding ring 41. The number of the blocking rods 45 is several, and the several blocking rods 45 are evenly distributed. The end of the blocking rod 45 away from the first threaded ring 44 is connected to the sliding ring 41. The outer surface of the ring 41 is squeezed and adapted. By setting the blocking rod 45, the sliding ring 41 can be blocked to prevent the sliding ring 41 from sliding on the outer surface of the track rod 3. During use, when it is necessary to adjust the lateral position of the placement mechanism 5, the operator rotates the first threaded ring 44 to move the blocking rod 45 away from the sliding ring 41, and then moves the fixing frame 42 to cause the sliding ring 41 to move laterally on the outer surface of the track rod 3. After the movement, the operator rotates the first threaded ring 44 until the blocking rod 45 is squeezed against the outer surface of the sliding ring 41, thereby achieving the effect of preventing the sliding ring 41 from sliding.

[0032] The second embodiment, as Figure 5 As shown, a fixing plate 52 is fixedly connected to the inner wall of the bottom frame 51. The number of the fixing plates 52 is several, and the several fixing plates 52 are symmetrically fixedly connected to the inner wall of the bottom frame 51. The side of the fixing plate 52 away from the inner wall of the bottom frame 51 is fixedly connected to the limiting ball 53. By setting up several fixing plates 52, the bottom of the bearing placed in the inner cavity of the bottom frame 51 can be supported. By setting up the limiting ball 53, the rotating sleeve 54 can generate stable rotation on the outer surface of the limiting ball 53. The outer surface of the limiting ball 53 is rotatably connected to the rotating sleeve 54. The rotating sleeve 5 A roller 55 is fixedly connected to the side away from the limiting ball 53. The outer surface of the roller 55 is provided with a plurality of grooves. By providing a rotating sleeve 54, the roller 55 can be driven to rotate on the outer surface of the limiting ball 53. Then, when the roller 55 rubs against the bearing, the roller 55 generates stable rotation. During use, the operator places the bearing in the inner cavity of the bottom frame 51. When the bearing rotates, the outer surface of the bearing contacts the roller 55. Under the action of friction, the rotating sleeves 54 on both sides of the roller 55 rotate on the outer surface of the limiting ball 53, thereby generating stable rotation of the roller 55.

[0033] The third embodiment, as Figure 6-Figure 8As shown, the locking mechanism 6 includes a first connecting frame 61, which is fixedly connected to the outer surface of the bottom frame 51, and a locking tube 62 is fixedly connected to the inner cavity of the first connecting frame 61. By setting the first connecting frame 61, the locking tube 62 can be connected to the outer side of the bottom frame 51. By setting the locking tube 62, the locking barrel 65 can be limited, so that the locking barrel 65 can produce a stable up and down movement effect in the inner cavity of the locking tube 62. The outer surface of the locking tube 62 is penetrated by a track frame 63, and a sliding block 64 is slidably connected to the inner cavity of the track frame 63. The lower surface of the sliding block 64 is fixedly connected to a spring 66, and the bottom end of the spring 66 is fixedly connected to the bottom surface of the inner cavity of the track frame 63. By setting the track frame 63, The sliding block 64 can be limited so that the sliding block 64 can produce an effect of vertical up and down movement in the inner cavity of the track frame 63. By setting the spring 66, the sliding block 64 can be squeezed, so that after the sliding block 64 slides downward and is not subjected to the downward squeezing force, the sliding block 64 can produce a rebound effect. The sliding block 64 is fixedly connected to a locking barrel 65 at one end close to the inner cavity of the locking tube 62. A locking groove is provided at the inner cavity of the locking barrel 65. The outer surface of the locking barrel 65 is fixedly connected to an anti-skid plate 67. The number of the anti-skid plates 67 is several, and the anti-skid plates 67 are evenly distributed. By setting the locking barrel 65, the locking rod 612 can be limited. By setting the locking groove in the inner cavity of the locking barrel 65, the stability can be increased. The friction force on the outer surface of the positioning rod 612 makes the positioning rod 612 tightly inserted in the inner cavity of the positioning barrel 65. By setting the anti-slide plate 67, after the positioning barrel 65 moves downward, it can contact the inner wall of the positioning ring 68, thereby preventing the positioning barrel 65 from rebounding. The bottom end of the positioning tube 62 is fixedly connected with a positioning ring 68, and the inner wall of the positioning ring 68 is frictionally adapted to the outer surface of the anti-slide plate 67. The lower surface of the positioning ring 68 is fixedly connected with a second threaded ring 69, and the inner cavity of the second threaded ring 69 is threadedly connected with a second threaded rod 610. By setting the positioning ring 68, it can contact the anti-slide plate 67 at the bottom of the positioning barrel 65. By setting the second threaded ring 69, the second threaded rod 610 can be limited, so that When the threaded rod 610 rotates, the top end of the second threaded rod 610 can move up and down. The locking mechanism 6 also includes a second connecting frame 611, which is fixedly connected to the outer side of the top frame 71. The inner cavity of the second connecting frame 611 is fixedly connected to a locking rod 612. The outer surface of the bottom end of the locking rod 612 is fixedly connected to an internal threaded plate 613. The outer surface of the internal threaded plate 613 is frictionally adapted to the inner wall of the locking barrel 65. The inner surface of the internal threaded plate 613 is threadedly connected to the second threaded rod 610. By providing the locking rod 612, the top frame 71 and the bottom frame 51 can be connected together. By providing the internal threaded plate 613, the friction between the locking rod 612 and the inner cavity of the locking barrel 65 can be increased.During use, after placing the bearing in the inner cavity of the bottom frame 51, the operator inserts the locking rod 612 into the inner cavity of the locking barrel 65. During the squeezing process, the locking barrel 65 moves downward, thereby making the anti-slip plate 67 tightly contact the inner ring of the locking ring 68. The operator then rotates the second threaded rod 610 so that the second threaded rod 610 rotates into the inner cavity of the internal threaded plate 613, thereby achieving the effect of tightly contacting the bottom frame 51 and the top frame 71.

[0034] The upper surface of the top frame 71 is fixedly connected to a fixing frame 72, and a third threaded ring 73 passes through the upper surface of the fixing frame 72, and a third threaded rod 74 is threadedly connected to the inner cavity of the third threaded ring 73. By providing the third threaded ring 73, the third threaded rod 74 can be limited, so that when the third threaded rod 74 rotates, the extrusion cover 77 can be squeezed toward the upper surface of the bearing, and the bottom end of the third threaded rod 74 is fixedly connected to a rotating plate 75, the outer surface of the rotating plate 75 is rotatably connected to the limiting sleeve 76, the lower surface of the limiting sleeve 76 is fixedly connected to the extrusion cover 77, and the inner surface of the extrusion cover 77 is fixedly connected to a gasket 78. By providing the rotating plate 75 and the limiting sleeve 76, the extrusion cover 77 will not rotate when the third threaded rod 74 rotates.

[0035] Working principle: The operator places the bearing in the inner cavity of the bottom frame 51. When the bearing rotates, the outer surface of the bearing contacts the roller 55. Under the action of friction, the rotating sleeves 54 on both sides of the roller 55 will rotate on the outer surface of the limiting ball 53, thereby making the roller 55 rotate stably. After the bearing is placed in the inner cavity of the bottom frame 51, the operator inserts the locking rod 612 into the inner cavity of the locking barrel 65. During the extrusion process, the locking barrel 65 moves downward, thereby making the anti-slip plate 67 tightly contact with the inner ring of the locking ring 68. Then the operator rotates the second threaded rod 610 so that the second threaded rod 610 rotates into the inner cavity of the internal threaded plate 613, thereby achieving the effect of tightly contacting the bottom frame 51 and the top frame 71. After the top frame 71 is connected to the bottom frame 51, the operator rotates the third threaded rod 74 so that the third threaded rod 74 drives the extrusion cover 77 to move downward, thereby making the gasket 78 tightly contact with the bearing.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without making creative efforts should fall within the scope of protection of the present invention.
