The embodiment of the application provides a turnover plate supporting device. The following will describe in detail.

Fig. 4 is a schematic structural view of an example of a pallet supporting device according to an embodiment of the present application. As shown in fig. 4, the turnover table supporting device 100 includes a base 110 and a limiting mechanism 120, wherein the base 110 is used for supporting the turnover table 200 and enabling the turnover table 200 to rotate on the base 110; the limiting mechanism 120 is disposed on the base 110 and is used for abutting against edges of two sides of the winding slot 210 on the turnover disc 200, so as to limit the cable 300 on the turnover disc 200 in the winding slot 210 of the turnover disc 200, and avoid the problem that the cable 300 on the turnover disc 200 is free to scatter and knotted.

As shown in fig. 1 and 4, the base 110 has a supporting surface 111, and a rotating shaft 112 is protruding from the supporting surface 111. When the turntable 200 is mounted to the turntable support unit 100, the rotation shaft 112 of the base 110 is rotatably mounted in the through hole 220 of the turntable 200 such that the turntable 200 can rotate about the rotation shaft 112.

The limiting mechanism 120 comprises a connecting seat 121 arranged on the supporting surface 111, and a shielding piece 140 connected with the connecting seat 121, wherein the shielding piece 140 comprises a shielding part 141, and the shielding part 141 and the rotating shaft 112 are arranged at a parallel interval. Because the shielding part 141 of the shielding member 140 is arranged at a parallel interval with the rotating shaft 112, after the peripheral turntable 200 is mounted on the rotating shaft 112 of the base 110, the shielding part 141 of the shielding member 140 can be abutted against two side edges of the winding groove 210 on the peripheral turntable 200, so that the cable 300 in the winding groove 210 of the peripheral turntable 200 is limited in the winding groove 210 in the process of rotating the peripheral turntable 200 around the rotating shaft 112, and the problem that the cable 300 on the peripheral turntable 200 is free to scatter and knotted is avoided.

It should be noted that, the distance between the shielding portion 141 of the shielding member 140 and the rotating shaft 112 may be determined according to the size of the turntable 200, and if the turntable 200 mounted on the base 110 is different in size, the distance between the shielding portions 141 of the shielding member 140 may be designed to be different, and only after the turntable 200 is mounted on the rotating shaft 112 of the base 110, the shielding portions 141 of the shielding member 140 may abut against both side edges of the winding slot 210 on the turntable 200.

Alternatively, the connecting seat 121 is movably connected with the shielding member 140, so that the shielding portion 141 moves relative to the connecting seat 121 in a direction approaching or separating from the rotating shaft 112. An elastic member 160 is provided on the connection base 121, and the elastic member 160 is connected to the shutter 140 to apply an elastic force to the shutter 140 to move the shutter 141 in a direction approaching the rotation shaft 112.

Therefore, after the turnover table 200 is mounted on the rotating shaft 112 of the base 110, the shielding portion 141 of the shielding member 140 can be stably abutted against the two side edges of the winding groove 210 on the turnover table 200 under the action of the elastic member 160, so that the cable 300 on the turnover table 200 is prevented from falling out from the gap between the turnover table 200 and the shielding member 140 due to the separation and abutment between the shielding member 140 and the turnover table 200 in the rotation process of the turnover table 200 around the rotating shaft 112.

It should be noted that the movable connection between the connection seat 121 and the shielding member 140 may be a rotatable connection between the connection seat 121 and the shielding member 140, a sliding connection between the connection seat 121 and the shielding member 140, or a simultaneous sliding connection and a rotatable connection between the connection seat 121 and the shielding member 140, so long as the shielding portion 141 is able to approach or separate from the rotation shaft 112.

The elastic force applied by the elastic member 160 to the shielding member 140 may be a pushing force or a pulling force, and specifically, the shielding portion 141 may be allowed to move in a direction approaching the rotation shaft 112 according to the structure and the mounting position of the elastic member 160.

In other embodiments, the shield portion 141 of the shield 140 is resilient. Specifically, the shielding member 140 is made of an elastic material such as plastic, rubber, or the like so that the shielding portion 141 has elasticity. This can also stabilize the shielding portion 141 against both side edges of the winding groove 210 on the turntable 200.

As shown in fig. 2 and 3, the shielding member 140 is rotatably connected to the connection base 121, and the shielding member 140 is disposed at an angle with respect to the rotation axis of the connection base 121 and the direction from the connection base 121 to the rotation shaft 112, so that the shielding portion 141 rotates with respect to the connection base 121 in a direction approaching or separating from the rotation shaft 112. Because the shielding member 140 is disposed at an angle relative to the rotation axis of the connecting seat 121 and the direction from the connecting seat 121 to the rotating shaft 112, when the shielding member 140 rotates about the rotation axis relative to the connecting seat 121, the shielding portion 141 can be close to or far from the rotating shaft 112, and the structure is relatively simple.

The elastic member 160 applies an elastic force to the shielding member 140 to rotate the shielding portion 141 in a direction approaching the rotation axis 112, so that the shielding portion 141 of the shielding member 140 can abut against both side edges of the winding slot 210 on the turntable 200.

In other embodiments, the shielding member 140 is rotatably connected to the connection base 121, and the shielding member 140 extends along the length direction of the rotation shaft 112 with respect to the rotation axis of the connection base 121. Thus, when the shutter 140 rotates about the rotation axis relative to the connection seat 121, the shutter portion 141 can be moved closer to or farther from the rotation shaft 112 as well.

In addition, the shielding member 140 may be slidably coupled to the coupling seat 121 in a direction from the coupling seat 121 to the rotation shaft 112. By controlling the shutter 140 to slide relative to the connecting seat 121, the shutter 141 can be moved closer to or farther from the rotation shaft 112 as well. The elastic member 160 applies an elastic force to the shielding member 140 to slide the shielding portion 141 in a direction approaching the rotation shaft 112, so that the shielding portion 141 of the shielding member 140 can be abutted against both side edges of the winding slot 210 on the turntable 200.

As shown in fig. 2 and 3, the connection base 121 includes a first abutting portion 1214 on a side of the shielding portion 141 away from the rotation shaft 112, the elastic member 160 is disposed between the first abutting portion 1214 and the shielding portion 141, one end of the elastic member 160 abuts against the first abutting portion 1214, and the other end of the elastic member 160 abuts against the shielding portion 141. Thus, the elastic member 160 can stably apply a pushing force to the shielding portion 141 of the shielding member 140, and the pushing force can rotate the shielding portion 141 of the shielding member 140 toward the rotation shaft 112. The elastic member 160 includes a spring, a torsion spring, rubber, etc., as long as it can apply a pushing force to the shielding portion 141 of the shielding member 140, which is not limited herein.

The first limiting groove 142 is formed on the side of the shielding portion 141 facing the first abutting portion 1214, and the other end of the elastic member 160 abuts against the groove bottom of the first limiting groove 142, so that the abutting between the other end of the elastic member 160 and the shielding portion 141 is more stable. A second limiting groove (not shown) is formed on one side of the first abutting portion 1214 facing the shielding portion 141, and one end of the elastic member 160 abuts against a bottom of the second limiting groove, so that the abutting between the one end of the elastic member 160 and the first abutting portion 1214 is more stable.

As shown in fig. 3, the shielding member 140 includes a connection portion 144 and a limiting portion 145, the connection portion 144 is connected with the shielding portion 141, and the connection portion 144 is rotatably connected with the connection base 121, so that the shielding member 140 is rotatably connected with the connection base 121. The limiting portion 145 is connected to one end of the connecting portion 144 away from the shielding portion 141.

In other embodiments, the elastic member 160 is located at one side of the limiting portion 145 away from the rotating shaft 112, one end of the elastic member 160 is connected to the connecting seat 121, and the other end of the elastic member 160 is connected to the limiting portion 145 to apply an elastic force to the limiting portion 145 to rotate the limiting portion 145 in a direction away from the rotating shaft 112, where the elastic force is a tensile force. When the elastic member 160 pulls the limiting portion 145 to rotate in a direction away from the rotating shaft 112, the abutting portion is simultaneously driven to rotate toward the rotating shaft 112. The elastic member 160 includes, but is not limited to, a tension spring, rubber, and the like.

As shown in fig. 2 and 3, an abutment 170 is further connected to the connection seat 121, and the abutment 170 abuts against the shielding member 140 to limit the distance that the shielding portion 141 moves toward the rotation shaft 112. The abutment member 170 can limit the distance that the shielding portion 141 of the shielding member 140 moves towards the rotating shaft 112 under the action of the elastic member 160, so that the shielding portion 141 of the shielding member 140 is prevented from being too close to the rotating shaft 112, and the shielding member 140 causes interference to the peripheral turntable 200 in the process of mounting the peripheral turntable 200 on the rotating shaft 112, so that the peripheral turntable 200 is inconvenient to mount.

Optionally, the abutment 170 is movably connected to the connection seat 121 to adjust the distance between the shielding portion 141 of the shielding member 140 and the rotating shaft 112. By moving the abutment 170 relative to the connection seat 121, the position of the abutment 170 can be changed, so that the extent of restriction of the abutment 170 on the moving distance of the shielding portion 141 toward the rotation shaft 112 is changed, and adjustment of the distance between the shielding portion 141 and the rotation shaft 112 is realized.

Therefore, after the peripheral turntable 200 is mounted on the rotating shaft 112 of the base 110, the position of the abutting piece 170 can be adjusted to change the distance between the shielding part 141 and the rotating shaft 112, so that the acting force between the shielding part 141 of the shielding piece 140 and the two side edges of the winding groove 210 on the peripheral turntable 200 is adjusted to a proper range, the situation that the acting force between the shielding part 141 of the shielding piece 140 and the two side edges of the winding groove 210 on the peripheral turntable 200 is too large to cause larger abrasion on the shielding part 141 of the shielding piece 140 or the two side edges of the winding groove 210 on the peripheral turntable 200 or the situation that the acting force between the shielding part 141 of the shielding piece 140 and the two side edges of the winding groove 210 on the peripheral turntable 200 is too small to cause weaker limiting effect of the shielding part 141 of the shielding piece 140 on the cable 300 in the winding groove 210 is avoided.

As shown in fig. 3, the abutment 170 includes a second abutment portion 172, and the second abutment portion 172 abuts against a side of the limiting portion 145 facing away from the rotation shaft 112. Therefore, when the elastic member 160 pushes the shielding portion 141 of the shielding member 140 to rotate toward the rotating shaft 112, the shielding portion 141 of the shielding member 140 drives the limiting portion 145 to rotate toward a direction away from the rotating shaft 112 through the connecting portion 144 until the second abutting portion 172 of the abutting member 170 abuts against a side of the limiting portion 145 away from the rotating shaft 112, and the rotation of the shielding member 140 is stopped.

The abutting piece 170 includes a connecting rod 171 extending along a direction from the connecting seat 121 to the rotating shaft 112, the connecting rod 171 is in threaded connection with the connecting seat 121, and the second abutting portion 172 is located at an end of the connecting rod 171 near the rotating shaft 112. By rotating the connecting rod 171 relative to the connecting seat 121, the connecting rod 171 can be moved along the length direction thereof, and the second abutting portion 172 is driven to approach or separate from the rotating shaft 112, so as to change the rotation angle of the shielding member 140.

In other embodiments, the connecting rod 171 of the abutment 170 extends along the length of the shaft 112. By rotating the connection rod 171 with respect to the connection base 121, the connection rod 171 can be moved in the longitudinal direction of the rotation shaft 112 thereof, and the height of the second abutment portion 172 can be changed, thereby changing the rotation angle of the shutter 140.

In other embodiments, a plurality of mounting positions (not shown) for detachably connecting with the abutment 170 are disposed on the connection seat 121, the plurality of mounting positions are located on one side of the limiting portion 145 away from the rotating shaft 112, and the plurality of mounting positions are sequentially distributed along a direction away from the rotating shaft 112. The abutment 170 is removably connected to one of a plurality of mounting locations.

It will be appreciated that by detachably connecting the abutment 170 to different mounting positions, the distance between the second abutment 172 of the abutment 170 and the rotation shaft 112 can be changed, and when the second abutment 172 of the abutment 170 at a different mounting position abuts against the limiting portion 145 of the shielding member 140, the shielding member 140 can be limited to different rotation angles.

As shown in fig. 3, the shielding portion 141 of the shielding member 140 is provided with a buffer member 150 toward the side of the rotation shaft 112. When the turnover table 200 is mounted on the rotation shaft 112 of the base 110, the buffer 150 on the shielding part 141 abuts against both side edges of the winding slot 210 on the turnover table 200, thereby buffering between the shielding part 141 and the turnover table 200 and ensuring that no gap exists between the shielding part 141 and both side edges of the winding slot 210 on the turnover table 200.

Wherein, the material of the buffer member 150 is a flexible material. The specific material of the buffer member 150 includes, but is not limited to, sponge, rubber, silica gel, foam, and the like.

As shown in fig. 3, the surface of the shutter 140 facing the rotation shaft 112 is provided with a guide slope 143, and the guide slope 143 is located at an end of the shutter 140 remote from the base 110. When the peripheral turntable 200 is mounted on the rotating shaft 112 of the base 110, the peripheral turntable 200 abuts against the guide inclined surface 143 to push the shielding part 141 of the shielding member 140 to move in a direction away from the rotating shaft 112, so that the peripheral turntable 200 is more conveniently mounted on the rotating shaft 112 of the base 110.

Specifically, the connection base 121 includes a bottom plate 1211 disposed opposite the support surface 111 of the base 110, and a connection plate 1213 connected to a side surface of the bottom plate 1211 facing away from the base 110. The side of the connection plate 1213 is opposite to the rotation shaft 112. The connection plate 1213 is perpendicular to the base plate 1211. On opposite sides of the connection plate 1213, protruding portions 1215 are protruded toward the rotation shaft 112, respectively, and the two protruding portions 1215 are rotatably connected to the shutter 140.

Wherein the shielding member 140 is provided in a plate shape, and a side surface of the shielding member 140 is provided opposite to a side surface of the connection plate 1213 at a distance. The limiting portion 145, the connecting portion 144 and the shielding portion 141 of the shielding member 140 are sequentially distributed in a direction away from the base 110, and opposite sides of the connecting portion 144 are respectively hinged with the two protruding portions 1215, so that the shielding member 140 is rotatably connected with the connecting seat 121.

The elastic member 160 is located between the shielding portion 141 and the connection plate 1213, one end of the elastic member 160 abuts against a side surface of the connection plate 1213 facing the rotation shaft 112, and the other end of the elastic member 160 abuts against a side surface of the shielding portion 141 facing away from the rotation shaft 112, so as to apply an elastic force to the shielding portion 141 to rotate the shielding portion 141 toward the rotation shaft 112.

A threaded hole is formed in a position of the connection plate 1213 opposite to the stopper 145, and the connection rod 171 passes through and is screwed to the threaded hole. The end of the connecting rod 171 away from the second abutting portion 172 is provided with an adjusting knob 173, and the connecting rod 171 can be conveniently driven to rotate relative to the connecting seat 121 through the adjusting knob 173.

Optionally, the base 110 is provided with a plurality of connection sites (not shown in the figure) corresponding to the connection sites 121 for detachably connecting with the connection sites 121, the plurality of connection sites are sequentially distributed along a direction away from the rotation shaft 112, and the connection sites 121 are detachably connected with one of the plurality of connection sites. By detachably connecting the connecting seat 121 with different connecting positions, the distance between the connecting seat 121 and the rotating shaft 112 can be changed, and the distance between the shielding portion 141 of the shielding member 140 and the rotating shaft 112 can be changed. Accordingly, the connecting base 121 can be connected to the corresponding connecting position according to the size of the turntable 200, so that the shielding portion 141 of the shielding member 140 is stably abutted against both side edges of the winding groove 210 on the turntable 200.

Wherein, the connecting position comprises a connecting hole, a connecting column for being inserted into the connecting hole is arranged on the connecting seat 121, and the distance between the connecting seat 121 and the rotating shaft 112 is changed by inserting the connecting column into different connecting holes, so that the distance between the shielding part 141 of the shielding piece 140 and the rotating shaft 112 is changed.

Alternatively, the connection base 121 is slidably connected to the base 110 along the direction from the connection base 121 to the rotation shaft 112. The base 110 is provided with a locking member 130, and the locking member 130 is connected with the connecting seat 121 to lock the connecting seat 121. Therefore, when the distance between the connecting seat 121 and the rotating shaft 112 needs to be adjusted, the locking member 130 can be firstly released from locking the connecting seat 121, then the connecting seat 121 slides to a proper distance relative to the base 110, and the connecting seat 121 is locked by the locking member 130, so as to prevent the connecting seat 121 from sliding relative to the base 110.

As shown in fig. 1 and 2, a sliding slot 1212 is formed on a side surface of the bottom plate 1211 of the connection seat 121, the sliding slot 1212 extends along a direction from the connection seat 121 to the rotating shaft 112, and the sliding slot 1212 penetrates through the bottom plate 1211. A locking hole 113 is formed in the base 110 at a position corresponding to the sliding groove 1212. The locker 130 includes a locking portion connected to one end of the locking bar, which passes through the sliding groove 1212 to be screw-coupled with the locking hole 113, and a locking bar partially overlapped with the bottom plate 1211 in a length direction of the locking bar.

When the locking lever is rotated to move the locking lever downward by a certain distance, the locking portion on the locking lever abuts against the bottom plate 1211 and presses the bottom plate 1211 against the base 110 to lock the connection seat 121. When the locking lever is reversely rotated to move the locking lever upward, the upper locking portion of the locking lever is separated from the bottom plate 1211, and at this time, the bottom plate 1211 of the connection base 121 can be slid with respect to the base 110 to adjust the distance between the connection base 121 and the rotation shaft 112.

As shown in fig. 1 and 2, a plurality of locking holes 113 are formed at positions of the base 110 corresponding to the sliding grooves 1212, the plurality of locking holes 113 are sequentially distributed along the extending direction of the sliding grooves 1212, and each locking hole 113 is respectively connected with a locking member 130, so that the connecting seat 121 slides along the extending direction of the sliding grooves 1212 more stably.

In addition, a plurality of locking holes 113 corresponding to the slide 1212 form a locking hole group, and a plurality of locking hole groups are provided on the base 110, and the plurality of locking hole groups are provided around the rotation shaft 112. Thus, the connection base 121 can be selectively connected with the locking holes 113 in different locking hole groups according to the requirement, so as to change the position of the connection base 121.

As shown in fig. 1 and 4, the number of the limiting mechanisms 120 is plural, and the limiting mechanisms 120 are disposed around the rotating shaft 112, so as to further improve the limiting effect on the cables 300 in the turnover tray 200.

As shown in fig. 1, a rolling element 115 is disposed on the supporting surface 111 of the base 110, and the distance between the rolling element 115 and the rotating shaft 112 is smaller than the distance between the connecting seat 121 and the rotating shaft 112. When the turntable 200 is mounted on the rotating shaft 112, the rolling members 115 can support the turntable 200 to reduce friction between the turntable 200 and the base 110, so that the turntable 200 rotates more smoothly.

The number of the rolling elements 115 is plural, and the plurality of rolling elements 115 are disposed around the rotation shaft 112, so that the turntable 200 is more stably supported on the base 110.

Wherein the rolling element 115 is a universal ball. The support surface 111 of the base 110 is provided with a mounting seat 114, the distance between the mounting seat 114 and the rotating shaft 112 is smaller than the distance between the seat and the rotating shaft 112, and the universal ball is mounted on the mounting seat 114 in a rolling way, so that the universal ball is more stably connected with the base 110.
