According to the above description, the three-way adjustable bolt connection includes a receiving pin portion 1, a plug pin portion 2, a connection member 3, and an adjusting portion 4. The pin bearing part 1 and the bolt part 2 are arranged on the two components; the upper end and the lower end of the connecting piece 3 are respectively positioned in the pin inserting part 2 in the pin bearing part 1 to play a role in connection; the adjusting part 4 is sleeved outside the connecting piece 3 and is positioned between the bearing pin part 1 and the bolt part 2. The connector 32 of the connecting piece 3 is arranged in the pin bearing sleeve 11 and is positioned on the support sleeve 12; the connecting rod 31 of the connecting piece 3 passes through the supporting sleeve 12 and the adjusting part 4 in sequence, and then the tail end is in threaded connection with the pin sleeve 21. The connecting piece 3 can move along the radial direction of the pin bearing sleeve 11, the connecting rod 31 has a certain space for radial movement in the supporting sleeve 12, so that when the pin bearing part 1 and the pin inserting part 2 are inserted, even if the pin bearing part and the pin inserting part have some deviation in the axial direction and are not coaxial, the radial displacement of the connecting piece 3 in the pin bearing sleeve 11 can be corrected, and the whole inserting operation can be smoothly completed. The radial adjustment of the connecting rod 31 in the support sleeve 12 is the first direction adjustment in the three-way adjustable bolted connection.
Particularly, the outer diameter of the connecting rod 31 is smaller than the outer diameter of the connecting head 32 and the inner diameter of the supporting sleeve 12, and the outer diameter of the connecting head 32 is larger than the inner diameter of the supporting sleeve 12.

The outer diameter of the connecting rod 31 is smaller than the outer diameter of the connecting head 32 and the inner diameter of the supporting sleeve 12, and the connecting rod 31 has a certain space for radial movement in the supporting sleeve 12, so that when the pin receiving part 1 and the pin receiving part 2 are spliced, even if the connecting rod is not coaxial and has some deviation in the axial direction, as long as the connecting head 32 of the connecting piece 3 fixed on the pin receiving sleeve 11 can smoothly enter the pin receiving sleeve 11, and the supporting sleeve 12 can be normally screwed on the open end of the pin receiving sleeve 11, the axial deviation can be corrected through the radial displacement of the connecting piece 3 in the pin receiving sleeve 11, so that the splicing work between the pin receiving part 1 and the pin receiving part 2 can be smoothly completed.
Further, a floating sleeve 13 is arranged in the pin bearing sleeve 11; the floating sleeve 13 is sleeved on the periphery of the connecting rod 31; the lower end of the floating sleeve 13 is attached to the upper end of the supporting sleeve 12; the lower end of the connector 32 is attached to the upper end of the floating sleeve 13; the floating sleeve 13 is radially movable along the cotter sleeve 11.
A floating sleeve 13 is also provided within the cotter sleeve 11 in accordance with the description above. The floating sleeve 13 is sleeved on the periphery of the connecting rod 31 and moves along the radial direction of the pin bearing sleeve 11. On one hand, the floating sleeve 13 plays a role in intermediate connection between the connector 32 and the support sleeve 12, so that the stress effect of the connector 32 is improved; on the other hand, the floating sleeve 13 is matched with the connecting rod 31, the connecting piece 3 has a certain radial movable space in the pin bearing sleeve 11, so that slight deviation between the pin bearing part 1 and the plug pin part 2 can be corrected through radial displacement of the connecting piece 3 in the pin bearing sleeve 11.
In particular, the outer diameter of the floating sleeve 13 is smaller than the inner diameter of the support sleeve 11, so that the floating sleeve 13 can move radially along the support sleeve 11 before the connection element 3 is completely fixed by the adjustment portion 4; the outer diameter of the connecting rod 31 should be slightly smaller than the inner diameter of the floating sleeve 13 to ensure that the connecting rod 31 can pass through the inner circumference of the floating sleeve 13.
Further, the adjusting portion 4 includes an adjusting nut 41 and a screw 42; the adjusting nut 41 is sleeved on the connecting rod 31 in a threaded manner; the lower end of the adjusting nut 41 is attached to the upper end of the latch sleeve 21; the periphery of one side of the connecting rod 31 is provided with a sliding groove 33 along the axial direction; after the screw 42 passes through the adjusting nut 41 from outside to inside, the tail end of the screw can be attached to the bottom of the sliding groove 33; the screw 42 is screwed to the adjusting nut 41.
According to the above description, the adjusting portion 4 includes the adjusting nut 41 and the screw 42. An adjustment nut 41 is threaded on the connecting rod 31 above the latch sleeve 21. After the screw 42 passes through the adjusting nut 41, the tip end thereof can be engaged in the slide groove 33 of the connecting rod 31. The screw 42 is screwed, and the matching between the screw 42 and the sliding groove 33 can drive the connecting piece 3 to move up and down along the axial direction of the bolt part 2, so that the connector 32 can be fixed in the bolt part 1. After the screw 42 is loosened and the screw 42 is released from the sliding slot 33, the adjusting nut 41 can move up and down along the axial direction of the connecting rod 31. The adjustment nut 41 is adjusted in the axial direction of the connecting rod 31, i.e. is the second direction adjustment in the three-way adjustable bolt connection.
Specifically, after the screw 42 is screwed until the screw 42 is engaged in the sliding groove 33, the adjusting nut 41 is rotated to drive the connecting rod 31 to rotate through the engaging action of the screw 42, and further drive the connecting piece 3 to move up and down along the axial direction of the plug pin portion 2. After the connector 32 enters the socket 11 and the support sleeve 12 is screwed into the open end of the socket 11, the preliminary insertion between the socket 1 and the plug 2 is completed. Subsequently, the screw 42 is screwed, and the adjusting nut 41 is screwed to move the connecting member 3 downward, so that the connecting head 32 is pressed against the supporting sleeve 12 (floating sleeve 13) to realize the pressing fit between the connecting head 32 and the supporting sleeve 12 (and the floating sleeve 13), and the connecting head 32 is fixed in the pin bearing sleeve 11 to complete the fixation between the pin bearing portion 1 and the pin portion 2, and the first direction adjustment in the three-way adjustable bolt connecting member is completed. Then, the screw 42 is loosened to separate the screw 42 from the sliding groove 33, the adjusting nut 41 is rotated, the adjusting nut 41 can move on the connecting rod 31, at this time, the adjusting nut 41 is rotated downward, the adjusting nut 41 can be pressed towards the latch sleeve 21 until the adjusting nut 41 cannot be rotated, the adjusting nut 41 is adjusted in place, and the second direction adjustment in the three-direction adjustable bolt connection is completed.
Further, the adjusting portion 4 further comprises a fastening nut 43; the fastening nut 43 is sleeved outside the connecting rod 31 in a threaded manner; the tightening nut 43 is positioned above the adjusting nut 41; the upper end of the fastening nut 43 is attached to the lower end of the support pin sleeve 11.
According to the above description, the adjustment part 4 further comprises a tightening nut 43. The fastening nut 43 is threaded on the connecting rod 31 and is located between the adjusting nut 41 and the pin sleeve 11. The tightening nut 43 is adjusted in the axial direction of the connecting rod 31, i.e., is the third-direction adjustment in the three-direction adjustable bolt connection.
Specifically, after the adjusting nut 41 is adjusted in place, the tightening nut 43 is rotated to press the pin-bearing sleeve 11 until the tightening nut 43 cannot be rotated, the tightening nut 43 is adjusted in place, the third direction adjustment in the three-direction adjustable bolt connector is completed, and the integral plugging work of the three-direction adjustable bolt connector is also completed.
In particular, the space for movement between the receiving pin portion 1 and the inserting pin portion 2 may be limited due to the limitation of the site construction conditions, and the adjustment work of the adjusting portion 4 may not be completed by one adjustment, requiring the adjustment nut 41, the screw 42, and the fastening nut 43 to be screwed several times. However, no matter how many times the adjustment is needed, the adjustment process is to fix the bolt part 1 and the bolt part 2 (i.e. the joint 32, the support sleeve 12 and the floating sleeve 13 are tightly matched), adjust the bolt 41 (to press the bolt sleeve 21), and adjust the fastening nut 43 (to press the bolt sleeve 11).
Further, a spherical concave surface 14 is annularly formed at the upper end of the inner periphery of the floating sleeve 13; the lower end of the connector 32 is annularly provided with a spherical convex surface 34; the spherical convex surface 34 is connected with the spherical concave surface 14 in a sliding way; the inner diameter of the floating sleeve 13 is larger than the outer diameter of the connecting rod 31.
According to the above description, a spherical structure is arranged between the connector 32 and the floating sleeve 13, and the two are in sliding fit through the spherical structure; the inner diameter of the floating sleeve 13 is larger than the outer diameter of the connecting rod 31. Through the cooperation between spherical convex surface 34 and spherical concave surface 14, can ensure the complete cooperation between floating sleeve 13 and connecting piece 3, also can increase the contact surface between floating sleeve 13 and the connecting piece 3, reduce stress concentration, improve the atress condition of connector 32. Furthermore, more importantly, when there is an assembly error between the two components, which results in a small included angle between the axis of the pin receiving portion 1 and the axis of the pin portion 2, the connector 32 (i.e. the connector 3) is coaxial with the pin portion 2 through the spherical sliding fit between the spherical convex surface 34 and the spherical concave surface 14, and the floating sleeve 13 is still coaxial with the pin receiving portion 1. Therefore, when the axis of the pin bearing part 1 and the axis of the pin inserting part 2 have a smaller angle, the pin bearing part 1 and the pin inserting part 2 can be smoothly inserted through spherical surface matching, and the fixed connection work of the whole bolt connecting piece is completed.
In particular, the inner diameter of the floating sleeve 13 is only slightly larger than the outer diameter of the connecting rod 31, and the difference between the inner diameter and the outer diameter cannot be too large, so as to avoid the subsequent failure of the tightening nut 43 to fit the pin-bearing sleeve 11, which results in the failure of the third-direction adjustment. The angular offset that can be set by the spherical structure can therefore only be achieved within a relatively small range.
Furthermore, a steel bar 5 is respectively fixed on the pin bearing sleeve 11 and the pin inserting sleeve 21 in a threaded manner; one reinforcing steel bar 5 is arranged on one side, away from the pin sleeve 21, of the pin sleeve 11, and the other reinforcing steel bar 5 is arranged on one side, away from the pin sleeve 11, of the pin sleeve 21.
Further, the lower end of the support sleeve 12 is provided with a clamping groove 15. The slot 15 may facilitate the operator to rotate the support sleeve 12.
The above description is only an embodiment of the present invention, and is not intended to limit the scope of the present invention, and all equivalent structures or equivalent processes performed by the present invention or directly or indirectly applied to other related technical fields are included in the scope of the present invention.
