As shown in fig. 1-2, a bolt connection mechanism provided by an embodiment of the present application includes a connection sleeve 1, a connection bolt 2 in threaded connection with the connection sleeve 1, a rotary driving member 3 assembled in the connection sleeve 1 and capable of rotating along with the connection bolt 2, and a rotary top member 4 in threaded connection with the connection sleeve 1 and capable of being driven to rotate by the rotary driving member 3.
The connecting sleeve 1 is provided with a first internal thread 11 and a second internal thread 12 with opposite directions of rotation.
The rotating top member 4 is provided with a first external thread 43 and the connecting bolt 2 is provided with a second external thread.
The rotating top member 4 is at least partially located in the coupling sleeve 1, and the first external thread 43 is engaged with the first internal thread 11.
The connecting bolt 2 passes through the rotating top member 4 and the second external thread engages with the second internal thread 12.
The rotary drive member 3 is fitted between the connecting bolt 2 and the rotary top member 4, and the rotary top member 4 is movable relative to the rotary drive member 3 in the axial direction of the connecting sleeve 1.
The bolt connecting mechanism that this application provided can be used to the headlight installation of car. The bolt connection mechanism comprises a connection sleeve 1, a connection bolt 2, a rotary transmission member 3 and a rotary jacking member 4.
As shown in fig. 5-7, the headlight snaps on the outside of the adapter sleeve 1 when the headlight is mounted. The connecting sleeve 1 is located between the first connecting plate 5 and the second connecting plate 6. The connecting bolt 2 passes through the connecting sleeve 1, and the connecting bolt 2 is used for fixing the connecting sleeve 1 between the first connecting plate 5 and the second connecting plate 6. When the connecting sleeve 1 is fixed, the gland 21 at the head end of the connecting bolt 2 presses the first connecting plate 5, and the tail end of the connecting bolt 2 is screwed in the threaded hole of the second connecting plate 6.
In order to compensate for the play between the headlight and the first connecting plate 5, so that the connecting sleeve 1 and the headlight do not move during assembly, a rotary drive 3 is arranged in the connecting sleeve 1, and a rotary clamping element 4 is screwed onto the end of the connecting sleeve 1 facing the first connecting plate 5.
The rotating transmission member 3 is used for transmitting the rotation of the connecting bolt 2 to the rotating top member 4, thereby driving the rotating top member 4 to rotate.
Since the rotary top member 4 is screwed to the coupling sleeve 1, the rotary top member 4 is rotated with the rotary transmission member 3 and can move in the axial direction of the coupling sleeve 1. The rotating ejector 4 can move toward the first connection plate 5 side to eject the first connection plate 5, thereby making up a gap between the headlamp and the first connection plate 5.
The rotary transmission member 3 is fitted between the connecting bolt 2 and the rotary jacking member 4. The rotating transmission member 3 can be a U-shaped connecting piece, the open end of the rotating transmission member 3 is inserted or clamped with the rotating jacking piece 4, and the closed end of the rotating transmission member 3 is pre-tightened or clamped with the connecting bolt 2.
When connecting bolt 2 is screwed up or unscrews and rotates, rotating transmission spare 3 can rotate along with connecting bolt 2, and then drives rotatory top member 4 and rotates.
The rotary transmission member 3 and the connecting bolt 2 are assembled together in a pre-tightening way. The pretightening force between the rotary transmission piece 3 and the connecting bolt 2 can be adjusted as required.
When the resistance that rotatory driving medium 3 received is less than the pretightning force between rotatory driving medium 3 and connecting bolt 2, rotatory driving medium 3 can rotate with connecting bolt 2 an organic whole syntropy. When the resistance that the rotating transmission member 3 receives is greater than the pretightening force between rotating transmission member 3 and connecting bolt 2, rotating transmission member 3 can remain motionless for pivoted connecting bolt 2.
The rotary driving member 3 is clamped or inserted with the rotary jacking member 4. The rotating transmission member 3 can drive the rotating jacking member 4 to rotate. The rotary thrust element 4 can be displaced relative to the rotary drive element 3 in the axial direction of the connecting sleeve 1, i.e. in the axial direction of the connecting sleeve 1, the rotary drive element 3 and the rotary thrust element 4 are in a clearance fit and can slide relative to one another. When the rotating top member 4 moves towards the first connecting plate 5 along the axial direction of the connecting sleeve 1, the rotating transmission member 3 is at least partially clamped or inserted with the rotating top member 4 to ensure that the rotating top member 4 can be driven to rotate at any time.
When the end of the rotating top member 4 tightly abuts against the first connecting plate 5, and when the friction force between the rotating top member 4 and the first connecting plate 5 is greater than the pre-tightening force between the rotating transmission member 3 and the connecting bolt 2, and the connecting bolt 2 continues to rotate, the rotating transmission member 3 and the rotating top member 4 do not rotate along with the connecting bolt 2, but remain stationary.
In order to achieve a displacement of the rotary clamping element 4 in the axial direction along the connecting sleeve 1 in the opposite direction to the connecting bolt 2, a first internal thread 11 and a second internal thread 12 are provided in the connecting sleeve 1, wherein the first internal thread 11 and the second internal thread 12 are screwed in opposite directions. The outer peripheral surface of the rotary tightening member 4 has a first male screw 43 having the same direction as the direction of the screw of the first female screw 11. The connecting bolt 2 has a second external thread (not shown) having the same direction as the direction of the second internal thread 12. The center of the rotating top member 4 has a through hole for the connection bolt 2 to pass through.
When installed, a portion of the rotating tightening member 4 is located in the coupling sleeve 1, the first external thread 43 is engaged with the first internal thread 11, and another portion of the rotating tightening member 4 is located outside the coupling sleeve 1. The coupling bolt 2 passes through the rotary tightening member 4 and the coupling sleeve 1, and the second external thread of the coupling bolt 2 is engaged with the second internal thread 12.
Since the first internal thread 11 is threaded in the opposite direction to the second internal thread 12, the rotating top member 4 will turn and move towards the first connecting plate 5 when the connecting bolt 2 is tightened and moves towards the second connecting plate 6; when the connecting bolt 2 is unscrewed from the second connecting plate 6, the rotating top member 4 will rotate away from the first connecting plate 5 and move towards the connecting sleeve 1.
With reference to fig. 5 to 7, when the headlamp is installed by using the bolt connection mechanism, the headlamp is clamped with the connection sleeve 1, and the connection sleeve 1 is located between the first connection plate 5 and the second connection plate 6. The connecting bolt 2 is firstly screwed so that the connecting bolt 2 moves towards the second connecting plate 6, and the rotary driving member 3 integrally rotates along with the connecting bolt 2 in the same direction and drives the rotary jacking member 4 to rotate in the same direction. The rotating top member 4 rotates and moves towards the first connecting plate 5 until the rotating top member 4 abuts against the first connecting plate 5, so that the gap between the headlamp and the first connecting plate 5 is adaptively compensated. After the rotating top member 4 tightly abuts against the first connecting plate 5, the friction force between the rotating top member 4 and the first connecting plate 5 is larger than the pretightening force of the rotating transmission member 3 and the connecting bolt 2, and when the connecting bolt 2 is continuously screwed, the rotating top member 4 and the rotating transmission member 3 are kept still. And continuing to tighten the connecting bolt 2, continuing to move the connecting bolt 2 towards the second connecting plate 6 until the tail end of the connecting bolt 2 is in threaded connection with the threaded hole of the second connecting plate 6, and pressing the first connecting plate 5 by the pressing cover 21 at the head end of the connecting bolt 2 to finish the installation of the headlamp. In the process, the headlamp is kept at the original position, and the headlamp cannot be displaced in the axial direction of the connecting sleeve 1, so that the matching relation between the headlamp and peripheral parts is better ensured.
When dismantling, unscrew connecting bolt 2, the frictional force between rotatory top piece 4 and the first connecting plate 5 reduces, and rotatory driving medium 3 moves in driving rotatory top piece 4 towards connecting sleeve 1 along with connecting bolt 2 an organic whole syntropy rotates.
In one embodiment, as shown in fig. 2, the rotary drive member 3 is provided with a clamping element 31, the clamping element 31 being clamped on the connecting screw 2.

When the rotating transmission member 3 rotates, the insertion end 32 contacts with the slot walls at the two sides of the slot 44, thereby driving the rotating top member 4 to rotate. The slot 44 is slidable relative to the insertion end 32 when the rotatable tightening member 4 is moved in the axial direction of the coupling sleeve 1. The length of the insertion end 32 inserted into the slot 44 is greater than the maximum distance that the rotating top member 4 can move towards the first connection plate 5 side, so that it is ensured that at least part of the insertion end 32 is always in the slot 44, and the rotating top member 4 can be driven to rotate at any time.
