Detailed description of the invention
For making the technical problems to be solved in the utility model, technical scheme and advantage clearly, be described in detail below in conjunction with the accompanying drawings and the specific embodiments.
The utility model easily causes the rotatory force of stop to be transmitted on bolt after directly contacting with bolt for existing stop, thus cause the problem of bolt falling, a kind of rotational pin structure is provided, add position limiting structure, avoid bolt follow the rotation of stop and rotate to such an extent as to the problems such as the bolt looseness caused.
As shown in Figure 1 and Figure 2, a kind of rotational pin structure of the utility model embodiment, comprising: the first rotational pin structure 1, second rotational pin structure 2 and bolt 3; Wherein,
Described first rotational pin structure 1 comprises first chassis 101 and first shank 102 with coaxial through-hole; Described second rotational pin structure 2 comprises second chassis 201, second shank 202 and the limiting section 203 with coaxial through-hole, and through-hole wall has screw thread; The screw rod of described bolt 3 passes the through hole of described first rotational pin 1 and the through hole of described second rotational pin structure 2, by the threaded engagement of the through-hole wall of described second rotational pin structure 2; Wherein,
Described first shank 102 is provided with stopper slot, and the profile of described limiting section 203 mates with described stopper slot and inserts in described stopper slot.
Recognized by said structure, the rotational pin structure of the utility model embodiment is for connecting stop and tail-gate.As shown in Figure 3, second rotational pin structure 2 can be welded on stop stiffener 4, as being welded on stop stiffener 4 by the second chassis 201, and the second shank 202 of the second rotational pin structure 2 and limiting section 203 can through the via hole on stop stiffener 4 and the via holes on tail-gate threshold 5.Like this, just stop 6 can be placed in the second rotational pin structure 2 afterwards, finally load onto the first rotational pin structure 1 of mating with the second rotational pin structure 2, bolt 3, through the through hole of the first rotational pin 1 and the through hole of the second rotational pin structure 2, is fixed by the threaded engagement of the second rotational pin structure 2 through-hole wall.Due to as shown in Figure 3, after first rotational pin structure 1 of this rotational pin structure and the second rotational pin structure 2 are connected, limiting section 203 inserts in stopper slot, the structure of stopper slot and limiting section 203 avoids rotatory force that bolt 3 conducted and rotates thereupon, and the bolt 3 caused loosens the problems such as disengaging.
Further, described stopper slot at least has a tangent plane, the axis being parallel of described tangent plane and through hole.
As everyone knows, limiting section inserts in stopper slot, as shown in Figure 4, the stopper slot of the first rotational pin structure 1 has the axis being parallel tangent plane with through hole, and the profile of the limiting section of the second rotational pin structure 2 mates with stopper slot, situation about rotating when just can effectively avoid being subject to rotatory force, as when only having a tangent plane, stopper slot is " D " type, obviously can play above-mentioned anti-rotation effect, certainly, when having multiple tangent plane, also this effect can be reached.
The rotational pin structure composition graphs 5 of the utility model embodiment is known, and the second rotational pin structure 2 of rotational pin structure is protected weldering by two and is connected with stop stiffener 4, then is connected to tail-gate threshold 5 by spot welding.So, just can be placed at opposite side stop 6 in the second rotational pin structure 2 fixed, bottom and the tail-gate threshold 5 of stop 6 are fitted.
But, because tail-gate threshold, rotational pin structural perimeter are all passed through two and protected weldering welding, easily cause distortion, cumulative limit will be caused, therefore, in the utility model embodiment, rotational pin structure adopts the first rotational pin structure and the second rotational pin structure to coordinate up and down, solves the problem of cumulative limit.
On the basis of above-described embodiment, in the rotational pin structure of another embodiment of the utility model, between the nut of described bolt and described first chassis, be provided with pad.
Between the nut and the first chassis of bolt, be provided with pad, after installing like this, can effectively avoid the Z-direction occurred in stop and rotational pin respective outer side edges process to beat.Further, described pad is spring shim.
Spring shim has certain elasticity, can realize better eliminating cumulative limit and z to the object of beating by distortion.
Further, described first rotational pin structure and described second rotational pin structure are all integrated formed structures.
The above is preferred embodiment of the present utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from principle described in the utility model; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
