Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0031] Refer to Figure 1 - Figure 2 , Figure 4 An embodiment provided by the present utility model: A self-lubricating copper sleeve structure of a support base includes a base 1. The inner wall of the base 1 is inserted with an outer cylinder 2, enabling the outer cylinder 2 to move vertically along the inner wall of the base 1. A quick installation mechanism is provided on the outer wall of the outer cylinder 2. The quick installation mechanism includes a fixed cylinder 4. The inner wall of the fixed cylinder 4 is slidably and rotatably connected with a pressing cylinder 5, enabling the pressing cylinder 5 to move vertically along the inner wall of the fixed cylinder 4 while being able to rotate. The inner wall of the pressing cylinder 5 is elastically connected with a cylinder 6 through a spring A8, enabling the cylinder 6 to always move upward along the inner wall of the pressing cylinder 5 without being affected by external forces. The bottom end of the pressing cylinder 5 is fixedly connected with a cone 9, enabling the cone 9 to move together when the pressing cylinder 5 moves vertically. The bottom end of the cone 9 is in contact connection with a clamping block 10, enabling the clamping block 10 to move outward due to the inclined surface of the cone 9 squeezing the outer wall of the clamping block 10.

[0032] Refer to Figure 1 - Figure 2 , Figure 4, the outer wall of the fixed cylinder 4 is fixedly connected to the outer wall of the outer cylinder 2, providing a fixed support effect for the fixed cylinder 4 through the outer wall of the outer cylinder 2. The outer wall of the fixed cylinder 4 is inserted into the inner wall of the base 1, enabling the fixed cylinder 4 to move vertically along the inner wall of the base 1. The outer wall of the column 6 is slidably connected to the inner wall of the pressing cylinder 5, enabling the column 6 to move vertically along the inner wall of the pressing cylinder 5. The outer wall of the conical body 9 is slidably connected to the inner wall of the fixed cylinder 4, enabling the conical body 9 to move vertically along the inner wall of the fixed cylinder 4. The outer wall of the clamping block 10 is slidably connected to the inner wall of the fixed cylinder 4, enabling the clamping block 10 to move horizontally along the inner wall of the fixed cylinder 4. The top end of the clamping block 10 is in contact connection with the bottom end of the base 1, enabling the fixed cylinder 4 to be fixed after being inserted into the base 1 due to the contact between the top end of the clamping block 10 and the bottom end of the base 1, and simultaneously driving the outer cylinder 2 to be fixed on the inner wall of the base 1.

[0033] Refer to Figure 1 , Figure 3 , the inner wall of the outer cylinder 2 is rotatably connected with an inner cylinder 3, enabling the inner cylinder 3 to rotate along the inner wall of the outer cylinder 2. The outer wall of the inner cylinder 3 is provided with oil drainage holes 16, enabling the lubricating oil in the interlayer between the outer cylinder 2 and the inner cylinder 3 to flow into the inner wall of the inner cylinder 3. The inner wall of the outer cylinder 2 is slidably connected with a ring 13, enabling the ring 13 to move vertically along the inner wall of the outer cylinder 2. The inner wall of the outer cylinder 2 is threadedly connected with a threaded column 12, enabling the threaded column 12 to move vertically along the inner wall of the outer cylinder 2 by rotation. The bottom end of the threaded column 12 is rotatably connected to the inner wall of the ring 13, enabling the bottom end of the threaded column 12 to rotate along the inner wall of the ring 13 and drive the ring 13 to move vertically.

[0034] Refer to Figure 2 , Figure 4 , the inner wall of the fixed cylinder 4 is provided with a chute 15, enabling the wedge block 7 to move vertically along the inner wall of the fixed cylinder 4. The inner wall of the chute 15 is slidably connected to the outer wall of the wedge block 7, enabling the pressing cylinder 5 to move along a specified position when moving vertically. The chute 15 is J-shaped, enabling the wedge block 7 to be clamped with the chute 15 by rotating the pressing cylinder 5 when the wedge block 7 moves to the bottom end of the chute 15, enabling the pressing cylinder 5 to drive the conical body 9 to be fixed at a specified position.

[0035] Refer to Figure 2 , the inner wall of the bottom end of the fixed cylinder 4 is fixedly connected with a T-shaped column 17, providing a fixed support effect for the T-shaped column 17 through the inner wall of the bottom end of the fixed cylinder 4. The outer wall of the T-shaped column 17 is elastically connected to the inner wall of the clamping block 10 through a spring B11, enabling the clamping block 10 to always maintain an inward movement effect without being affected by external forces.

[0036] Refer to Figure 2One end of the spring A8 is fixedly connected to the bottom end of the column 6, and the other end of the spring A8 is fixedly connected to the inner wall of the pressing cylinder 5, so that when the top end of the column 6 stops being pressed, the column 6 can drive the wedge block 7 to move upward due to the elastic force of the spring A8.

[0037] Reference Figure 1 - Figure 2 One end of the spring B11 is fixedly connected to the outer wall of the T-shaped column 17, and the other end of the spring B11 is fixedly connected to the inner wall of the clamping block 10, so that when the cone 9 stops squeezing the outer wall of the clamping block 10, the clamping block 10 can move inward due to the elastic force of the spring B11, and the top end of the outer cylinder 2 is threadedly connected with a bolt 14, so that the oil inlet at the top end of the outer cylinder 2 can be blocked by the bolt 14, so that the lubricating oil will not leak from the oil inlet.

[0038] Working principle: When using the device, first insert the outer cylinder 2 and the fixed cylinder 4 into the inner wall of the base 1 at the same time, and then press the top of the column 6 to drive the wedge block 7 to move downward, and then press the pressing cylinder 5 at the same time to drive the column 6 and the cone 9 to move downward. When the cone 9 moves downward, the inclined surface of the cone 9 will squeeze the outer walls of the two groups of clamping blocks 10 at the same time, so that the two groups of clamping blocks 10 move outward at the same time, and then rotate the pressing cylinder 5 to drive the column 6 to rotate, and make the wedge block 7 rotate along the bottom end of the slide groove 15. When it rotates to the specified position, first release the column 6, so that it moves upward due to the elastic force of the spring A8, and drives the wedge block 7 to clamp with the slide groove 15, so that the pressing cylinder 5 and the column 6 are fixed at the specified position, and the cone 9 can always keep squeezing the outer wall of the clamping block 10, so that the outer cylinder 2 and the fixed cylinder 4 are fixed to the inner wall of the base 1.

[0039] When it is necessary to release the fixation, first press the top end of the column 6 to release the wedge block 7 from the sliding groove 15, then rotate the pressing cylinder 5, and at the same time, the two sets of clamping blocks 10 will shrink inward due to the elastic force of the spring B11, and at the same time, the outer wall of the clamping block 10 will squeeze the inclined surface of the cone 9, so that it drives the pressing cylinder 5 to move upward, thereby releasing the fixation with the inner wall of the base 1, and then pull the device upward to make it detach from the inner wall of the base 1.

[0040] When the lubricating oil needs to be replaced, first unscrew the bolt 14 so that it no longer blocks the oil change port, then unscrew the two sets of threaded columns 12, and then pull the two sets of threaded columns 12 upward to drive the ring 13 to move upward. While the ring 13 moves upward, it will squeeze the old lubricating oil and discharge it along the oil change port. When it is completely discharged, first press down and tighten the threaded column 12, and then pour the lubricating oil from the oil change port into the inner wall of the outer tube 2. After the pouring is completed, tighten the bolt 14 to complete the replacement of the lubricating oil.

[0041] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
