DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] Embodiment 1: Please refer to Figure 1-Figure 5 The present invention provides a technical solution: an easily detachable adapter sleeve, comprising an adapter sleeve body, the adapter sleeve body comprising a fixed wall section 1, a conical fixing wall section 2 and a threaded wall section 3, an accommodating through cavity is provided at the inner center of the adapter sleeve body, a conical annular groove is provided on the inner walls of the fixed wall section 1 and the conical fixing wall section 2, a lower pressing sleeve 4 is provided at the conical annular groove of the fixed wall section 1, an extrusion plate 20 is fixedly connected to the bottom outer surface of the lower pressing sleeve 4 in an inclined manner, three accommodating holes arranged in a circumferential array are provided on the outer surface of the conical fixing wall section 2, and the conical fixing wall section 2 is provided with a conical annular groove. An adjusting plate 5 is arranged at the receiving hole at the conical annular groove inside the fixing wall section 2, a fixing plate 6 is arranged on the other side of the adjusting plate 5, a fixing gasket is arranged on the outer surface of the fixing plate 6, the fixing plate 6 is located inside the receiving hole, three through grooves 8 arranged in a circumferential array are opened on the outer surface of the fixed wall section 1, retaining rings 9 are arranged inside the three through grooves 8, a receiving groove 11 is opened on the outer surface of the retaining ring 9, and a limiting block 12 is arranged inside the receiving groove 11, and a convex ring 7 is arranged on the outer surface of the lower pressing sleeve 4 to apply force to the pressing sleeve 13 so that the pressing sleeve 13 presses the lower pressing sleeve 4 downward, so that the lower pressing sleeve 4 drives the extrusion plate 20 downward. When the extrusion plate 20 contacts the adjusting plate 5, as the lower pressing sleeve 4 moves downward, the adjusting plate 5 drives the fixing plate 6 to support outward, so that the fixing bushing on the fixing plate 6 fits tightly with the tapered hole of the bearing. When the lower pressing sleeve 4 drives the convex ring 7 downward, when the convex ring 7 contacts the limiting block 12, the convex ring 7 squeezes the limiting block 12 to move outward, so that the convex ring 7 passes smoothly. Then, when the limiting block 12 is located above the convex ring 7, the other end of the limiting block 12 is located at the convex ring 7. , when the lower pressing sleeve 4 wants to move upward, the convex ring 7 is blocked by the limit block 12, and the limit block 12 is blocked by the retaining ring 9, so that the convex ring 7 cannot move upward, thereby making the lower pressing sleeve 4 unable to move upward, and the extrusion plate 20 and the adjusting plate 5 are driven by the lower pressing sleeve 4 to make the fixing plate 6 fit tightly with the tapered hole of the bearing, thereby increasing the fixing force. When disassembly is required, the limit of the lower pressing sleeve 4 is released, so that the fixing plate 6 is retracted, thereby slightly applying force to the fixing sleeve, and the fixing sleeve can be disassembled, which facilitates the disassembly process of the entire fixing sleeve.

[0022] In this embodiment, a pressing sleeve 13 is fixedly connected to the top outer surface of the lower pressure sleeve 4, and an inner ring is fixedly connected to the bottom inner side of the pressing sleeve 13. The outer wall fixed sleeve of the conical annular groove at the center of the fixed wall section 1 is provided with a fixed sleeve plate, and a first spring 14 is fixedly connected between the fixed sleeve plate and the inner ring. Specifically, when the pressing sleeve 13 is pressed downward, the lower pressure sleeve 4 moves downward and the first spring 14 is deformed. When the lower pressure sleeve 4 is released from the limit, the pressing sleeve 13 is driven by the elastic action of the first spring 14 to reset the lower pressure sleeve 4.

[0023] In this embodiment, a connecting sleeve is provided on the outer surface of the fixed wall section 1, connecting blocks are fixedly connected to the outer surfaces of the three retaining rings 9, an adjusting sleeve 10 is fixedly connected between the three connecting blocks, and a second spring 15 is fixedly connected between the connecting sleeve and the adjusting sleeve 10. Specifically, when force is applied to the adjusting sleeve 10, the second spring 15 is deformed, and when force is stopped on the adjusting sleeve 10, the adjusting sleeve 10 is reset under the elastic action of the second spring 15.

[0024] In this embodiment, the outer surface of the adjustment plate 5 is fixedly connected to a rotating seat, and the outer surface of the locking plate 6 is fixedly connected to a rotating block, and the rotating block is rotatably connected to the outer surface of the rotating seat. Specifically, when the locking plate 6 contacts the tapered inner hole of the bearing, the rotating block rotates on the surface of the rotating seat, so that the locking plate 6 can adapt to tapered inner holes of different cones.

[0025] In this embodiment, a fifth spring is fixedly connected to the outer surface of the adjustment plate 5, and the other end of the fifth spring is fixedly connected to the interior of the fixed wall segment 1. A sliding rod is fixedly connected to the interior of the fixed wall segment 1, and the adjustment plate 5 is movably sleeved on the outer surface of the sliding rod. Specifically, when the lower pressure sleeve 4 is released from the limit, the elastic force of the fifth spring drives the adjustment plate 5 to reset, and the adjustment plate 5 is limited by the sliding rod, so that the adjustment plate 5 moves stably in a straight line.

[0026] In this embodiment, a slide groove 23 is provided on the outer surface of the adjustment block 18, and slide bars 24 are fixedly connected to both ends of the arc-shaped gasket 19. The slide bar 24 is movably connected to the inner wall of the slide groove 23. Specifically, when the arc-shaped gasket 19 and the adjustment block 18 are retracted or expanded, the slide bar 24 slides inside the slide groove 23, providing a channel for the recovery and expansion of the arc-shaped gasket 19.

[0027] In this embodiment, the diameters at both ends of the accommodating groove 11 are smaller than the diameter at the middle end, and the diameters at both ends of the limiting block 12 are smaller than the diameter at the middle end. Specifically, the above technical solution is adopted to prevent the limiting block 12 from completely detaching from the accommodating groove 11 when being squeezed.

[0028] In the specific implementation process, the tapered fixing wall section 2 is inserted into the bearing with a tapered hole, and then the adjusting sleeve 10 is forced downward to compress the second spring 15, so that the retaining ring 9 is separated from the limit block 12, and then the pressing sleeve 13 is forced downward to squeeze the lower pressing sleeve 4, so that the lower pressing sleeve 4 drives the extrusion plate 20 downward. When the extrusion plate 20 contacts the adjusting plate 5, as the lower pressing sleeve 4 moves downward, the adjusting plate 5 drives the fixing plate 6 to support outward, so that the fixing bushing on the fixing plate 6 fits tightly with the tapered hole of the bearing. When the lower pressing sleeve 4 drives the convex ring 7 downward, when the convex ring 7 contacts the limit block 12, the convex ring 7 squeezes the limit block 12 to move outward, so that the convex ring 7 passes smoothly, and then when the limit block 12 is located above the convex ring 7, stop applying force to the adjusting sleeve 10, so that the second spring 15 is reset, and the second spring 1 5 drives the adjusting sleeve 10 to reset, so that the retaining ring 9 squeezes the limiting block 12, so that the other end of the limiting block 12 is located above the convex ring 7. When the lower pressing sleeve 4 wants to move upward, the convex ring 7 is blocked by the limiting block 12, and the limiting block 12 is blocked by the retaining ring 9, so that the convex ring 7 cannot move up, thereby making the lower pressing sleeve 4 unable to move up, and the squeezing plate 20 and the adjusting plate 5 are driven by the lower pressing sleeve 4 to make the fixing plate 6 fit closely with the tapered hole of the bearing, thereby increasing the fixing force. When disassembly is required, pressure is applied downward to the adjusting ring, and the lower pressing sleeve 4 is reset under the elastic force of the first spring 14, so that the squeezing plate 20 is separated from the adjusting plate 5, and the fixing plate 6 is retracted and reset under the elastic force of the fifth spring, thereby applying a slight force to the fixing sleeve, and the fixing sleeve can be disassembled, which facilitates the disassembly process of the entire fixing sleeve.

[0029] Embodiment 2: Please refer to Figure 1 and Figure 6-Figure 7 The present invention provides a technical solution: a threaded tooth is provided on the outer surface of the threaded wall section 3, and three adjusting grooves 16 arranged in a circumferential array are provided on the outer surface of the threaded wall section 3. A third spring 17 is fixedly connected inside the adjusting groove 16, and an adjusting block 18 is fixedly connected to the other end of the third spring 17. An arc washer 19 is arranged between two adjacent adjusting blocks 18. Specifically, after the adapter sleeve is connected to the bearing, the nut is screwed onto the threaded tooth of the threaded wall end, so that one end of the nut contacts the arc washer 19, and the other end of the arc washer 19 contacts the surface of the bearing. The bearing is axially locked by the nut, and the arc washer 19 is used to block the bearing and the nut from direct contact with the bearing, thereby playing a certain locking and buffering role and further protecting the bearing.

[0030] In this embodiment, the outer surface of the adjustment block 18 is a smooth and inclined outer surface, and a telescopic rod is fixedly connected to the inside of the adjustment groove 16, and the other end of the telescopic rod is fixedly connected to the limit block 12. Specifically, by setting an inclined and smooth outer surface, when the bearing squeezes the adjustment block 18, the adjustment block 18 can be subjected to force, so that the adjustment block 18 shrinks inwardly. When the adjustment block 18 moves, the telescopic rod expands and contracts accordingly, and the third spring 17 is limited by the telescopic rod to prevent the third spring 17 from tilting and deforming.

[0031] In the specific implementation process, after the adapter sleeve is connected to the bearing, the nut is screwed onto the threaded teeth of the threaded wall end, so that one end of the nut contacts the arc washer 19, and the other end of the arc washer 19 contacts the surface of the bearing. The bearing is axially locked by the nut, and the arc washer 19 is used to block the bearing and the nut to avoid direct contact between the nut and the bearing, which plays a certain locking and buffering role and further protects the bearing. When the adapter sleeve is inserted into the bearing, when the limit block 12 and the arc washer 19 are blocked by the bearing, the bearing squeezes the limit block 12 and compresses the third spring 17, so that the adjustment block 18 is received in the adjustment groove 16, so that the threaded wall section 3 passes through the interior of the bearing. When the threaded wall section 3 is detached from the interior of the bearing, the third spring 17 drives the adjustment block 18 to reset, so that the adjustment block 18 extends out of the interior of the adjustment groove 16.

[0032] Embodiment 3: Please refer to Figure 1 and Figure 8 The present invention provides a technical solution: a fixed ring is fixedly sleeved on the outer surface of the fixed wall segment 1, a fourth spring 21 is fixedly connected to the bottom outer surface of the fixed ring, a stop sleeve 22 is fixedly connected to the bottom outer surface of the fourth spring 21, the stop sleeve 22 is sleeved on the outer surface of the fixed wall segment 1, and the fourth spring 21 is sleeved on the outer surface of the conical fixing wall segment 2.

[0033] In the specific implementation process, when the adapter sleeve is connected to the bearing and when the stop sleeve 22 is connected to the bearing, as the adapter sleeve is inserted, the fourth spring 21 is deformed, and when the adapter plate 6 is disengaged from the tapered hole of the bearing, the elastic restoring force of the fourth spring 21 bounces the adapter plate 6 away from the bearing, thereby further facilitating the disassembly of the adapter sleeve with the help of the elastic force of the fourth spring 21.

[0034] Working principle: When the present invention is in use, the tapered fixing wall section 2 is inserted into the bearing with a tapered hole, and then the adjusting sleeve 10 is forced downward to compress the second spring 15, so that the retaining ring 9 is separated from the limit block 12, and then the pressing sleeve 13 is forced downward to squeeze the lower pressing sleeve 4, so that the lower pressing sleeve 4 drives the extrusion plate 20 downward, and when the extrusion plate 20 contacts the adjusting plate 5, as the lower pressing sleeve 4 moves downward, the adjusting plate 5 drives the fixing plate 6 to support outward, so that the fixing bushing on the fixing plate 6 is tightly fitted with the tapered hole of the bearing, and when the lower pressing sleeve 4 drives the convex ring 7 downward, when the convex ring 7 contacts the limit block 12, the convex ring 7 squeezes the limit block 12 to move outward, so that the convex ring 7 passes smoothly, and then when the limit block 12 is located above the convex ring 7, stop applying force to the adjusting sleeve 10, so that the second spring 15 is reset, and the second spring 15 is released. The spring 15 drives the adjusting sleeve 10 to reset, so that the retaining ring 9 squeezes the limit block 12, so that the other end of the limit block 12 is located above the convex ring 7. When the lower pressing sleeve 4 wants to move upward, the convex ring 7 is blocked by the limit block 12, and the limit block 12 is blocked by the retaining ring 9, so that the convex ring 7 cannot move up, thereby making the lower pressing sleeve 4 unable to move up, and the extrusion plate 20 and the adjusting plate 5 are driven by the lower pressing sleeve 4 to make the fixing plate 6 fit tightly with the tapered hole of the bearing, thereby increasing the fixing force. When disassembly is required, pressure is applied downward to the adjusting ring, and under the elastic force of the first spring 14, the lower pressing sleeve 4 is reset, so that the extrusion plate 20 is detached from the adjusting plate 5, and under the elastic force of the fifth spring, the fixing plate 6 is retracted and reset, thereby applying a slight force to the fixing sleeve, the fixing sleeve can be disassembled, which facilitates the disassembly process of the entire fixing sleeve.

[0035] After the adapter sleeve is connected to the bearing, the nut is screwed onto the threaded teeth of the threaded wall end so that one end of the nut contacts the arc washer 19, and the other end of the arc washer 19 contacts the surface of the bearing. The bearing is axially locked by the nut, and the arc washer 19 is used to block the bearing and the nut to avoid direct contact between the nut and the bearing, thereby playing a certain locking and buffering role and further protecting the bearing. When the adapter sleeve is inserted into the bearing, when the limit block 12 and the arc washer 19 are blocked by the bearing, the bearing squeezes the limit block 12 and compresses the third spring 17, so that the adjustment block 18 is received in the adjustment groove 16, so that the threaded wall section 3 passes through the interior of the bearing. When the threaded wall section 3 is detached from the interior of the bearing, the third spring 17 drives the adjustment block 18 to reset, so that the adjustment block 18 extends out of the interior of the adjustment groove 16.

[0036] When the adapter sleeve is connected to the bearing and when the stop sleeve 22 is connected to the bearing, the fourth spring 21 is deformed as the adapter sleeve is inserted. When the adapter plate 6 is disengaged from the tapered hole of the bearing, the elastic restoring force of the fourth spring 21 causes the adapter plate 6 to be bounced apart from the bearing, thereby further facilitating the disassembly of the adapter sleeve with the help of the elastic force of the fourth spring 21.

[0037] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
