The anti-loosening support structure according to the embodiment of the present invention will be described in detail below.

The embodiment of the utility model provides an in locking bearing structure can be applied to the shuttle in commodity circulation field. As shown in fig. 2, the base 1 has a first surface 111. The first surface 111 can be understood as the upper surface of the base 1 and also as the bearing surface for the support of the support plate 4.

The first mounting hole 113 and the second mounting hole 121 are perpendicular to each other, and the third mounting hole 21 of the fixing shaft 2 has the same opening direction as the first mounting hole 113. The first and third mounting

holes

113 and 21 may be screw holes to be screw-coupled with the first bolt 3.

As shown in fig. 4, the fixing shaft 2 may be a pin shaft having a limiting surface, the limiting surface is a plane, and the third mounting hole 21 is disposed on the limiting surface. The second mounting hole 121 can be in clearance fit with the fixing shaft 2 to fix the fixing shaft 2, and circumferential rotation of the fixing shaft 2 can be prevented by arranging a planar limiting surface on the fixing shaft 2, so that stability of the fixing shaft is enhanced. Of course, the fixing shaft 2 may be a threaded column, both ends of which penetrate through the second mounting hole 121, and the threaded column is fixed by a nut, which can also play the same role, but it should be noted that the third mounting hole 21 on the fixing shaft 2 needs to be adjusted to be aligned with the first mounting hole 113, and then the fixing shaft is fixed by a nut.

The support plate 4 may be a guide plate of a shuttle car to carry the cargo box 200.

It should be noted that "upper" and "lower" in the embodiment of the present invention are terms indicating relative positional relationships between components, for example, the first surface 111 is the upper surface of the base 1, and the fixing shaft 2 is located below the first mounting hole 113.

Further, as shown in fig. 2, the base 1 may include: a groove portion 11 and a body portion 12. The groove portion 11 has a first surface 111, and the first surface 111 defines a first groove 112. The main body portion 12 is located on a side of the groove portion 11 away from the first surface 111. The main body 12 may be integrally formed with the recessed groove 11, or may be connected by welding, bonding, screwing, or the like, and is not particularly limited herein.

Further, as shown in fig. 2, a second mounting hole 121 is opened in the main body portion 12, and an extending direction of the second mounting hole 121 is parallel to a cross section of the first groove 112. It can also be understood that the extending direction of the second mounting hole 121 crosses the first groove 112, the direction from one side wall to the other side wall of the first groove 112, i.e., the extending direction F of the first groove 112 as shown in fig. 6, to achieve fixing of the fixing shaft 2 in this direction. Since the fixing shaft 2 is limited in the second mounting hole 121, the fixing shaft 2 can be effectively prevented from sliding along the extending direction F of the first groove 112 (i.e. the direction perpendicular to the cross section of the first groove 112). As shown in fig. 2, the cross-sectional shape of the first groove 112 may be substantially trapezoidal, or may be other shapes, which is not limited herein.

Further, as shown in fig. 2, the first mounting hole 113 is provided at the bottom surface of the first recess 112, i.e., the first mounting hole 113 extends downward from the bottom surface of the first recess 112 to communicate with the second mounting hole 121.

Further, the length of the first bolt 3 is equal to the sum of the depth of the first groove 112, the depth of the first mounting hole 113 and the depth of the third mounting hole 21, so that the first bolt 3 is arranged in the fixed shaft 2 to the maximum extent, the fastening performance is increased, and meanwhile, the top end of the first bolt 3 can be flush with the top surface of the support plate 4 or slightly lower than the top surface of the support plate 4, so that the top end of the first bolt 3 is prevented from being scratched by objects borne by the support plate 4. The first bolt 3 may be a countersunk head screw, when the support plate 4 is thin, a short screw, such as an M4 screw, may be used for the first bolt 3, and the length of the first bolt 3 may also be less than the sum of the three, as long as the first bolt 3 can be inserted into the third mounting hole 21 of the fixing shaft 2 and fix the support plate 4, and those skilled in the art may set the bolt according to actual conditions, and no particular limitation is imposed herein.

Further, a fourth mounting hole (not shown) is further opened on the bottom surface of the first groove 112 of the groove portion 11, the fourth mounting hole extends in the same direction as the first mounting hole 113, and the fourth mounting hole is spaced from the first mounting hole 113 in a direction perpendicular to the cross section of the first groove 112 (i.e. in the extending direction F of the first groove 112). That is, the fourth mounting hole is spaced apart from and parallel to the first mounting hole 113. The fourth mounting hole may have an internal thread.

Further, as shown in fig. 3, the anti-loose support structure further includes a nut 5 and a second bolt 6. The cross-sectional shape of the nut 5 matches the cross-sectional shape of the first groove 112. For example, when the cross-sectional shape of the first groove 112 is trapezoidal, the nut 5 may be a T-shaped nut 5 that mates with the first groove 112 such that the nut 5 fits into the groove. At the same time, the threaded hole of the nut 5 is aligned with the fourth mounting hole, preferably, the threaded hole of the nut 5 has a size equal to the size of the fourth mounting hole. As shown in fig. 5, the second bolt 6 is inserted into the threaded hole of the nut 5. With further reference to fig. 3, a second bolt 6 is inserted into the threaded hole and the fourth mounting hole of the nut 5 to fix the nut 5 on the base 1. The second bolt 6 is passed through the support plate 4, the nut 5, and the fourth mounting hole, and tightened to fix the support plate 4 to the base 1. Thus, the support plate 4 is fixed to the first surface 111 of the base 1 by the first bolt 3 and the second bolt 6.

Because the fixing shaft 2 is arranged in the second mounting hole 121 in a penetrating manner, the first bolt 3 is screwed into the third mounting hole 21 of the fixing shaft 2 (namely, the length of the first bolt 3 is greater than the height of the T-shaped nut), so that the connection tightness is improved, and even if the first bolt 3 is slightly loosened due to frequent collision and vibration, the fixing shaft 2 can be prevented from being displaced along the extending direction F of the first groove 112, and further the support plate 4 is prevented from being displaced along the direction. Meanwhile, since the support plate 4 is fixed in the extending direction F of the first groove 112 (the direction perpendicular to the cross section of the first groove 112), the T-shaped nut is also fixed in the extending direction F of the first groove 112, and even if the second bolt 6 is loosened, the T-shaped nut is not displaced in the direction, thereby preventing abnormal noise from occurring during the transportation of goods.

In addition, because the nut 5 is installed in the first groove 112 in a matching manner, that is, the nut 5 is limited by two side walls of the groove, the nut 5 cannot be displaced in a direction (extending direction of the second installation hole 121) parallel to the cross section of the first groove 112, and therefore, the support plate 4 cannot be displaced in the direction, and further, the fixing shaft 2 is also fixed in the direction, even if the first bolt 3 is loosened, or the support plate 4 is violently impacted due to the transportation of goods, the fixing shaft 2 cannot be displaced, and finally, the support plate 4 is limited in the two mutually perpendicular directions, and the abnormal sound caused by the loosening of the support plate 4 in the process of transporting goods is effectively avoided.

Of course, the nut 5 is not limited to a T-shaped nut, and for example, the nut 5 may be a hexagonal nut as long as the nut 5 can be limited by the two sidewalls of the first groove 112, and is not particularly limited herein. The second bolt 6 may be a countersunk head screw, and in particular, since the support plate 4 is thin, an M4 screw may be used as the screw.

Further, as shown in fig. 6 to 7, the utility model discloses a locking bearing structure can be applied to the shuttle, and this base 1 can be aluminum alloy ex-trusions. The structure of the aluminum alloy section bar can be directly used by the technicians in the field by the structure of the base 1 described above, and the processing process is omitted.

To sum up, the utility model discloses an anti loosening structure, because during fixed axle 2 wears to locate second mounting hole 121, can prevent that fixed axle 2 from sliding for base 1, and then prevent that the extending direction F of the first recess 112 of backup pad 4 from sliding, in addition, owing to be equipped with on the extending direction F of first recess 112 with second mounting hole 121 spaced fourth mounting hole, and nut 5 can be spacing by two lateral walls of first recess 112, and then can prevent that backup pad 4 from sliding along the extending direction of second mounting hole 121, therefore, realized the omnidirectional fastening to backup pad 4, effectively avoided backup pad 4 not hard up and the abnormal sound that produces in the transportation goods process.
