In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0065] like Figure 1 and Figure 2 As shown, this embodiment provides a vertical machine device, which can be used in a display device 4 production system, and is used to flip the display device 4 on the conveyor line 3 to a preset angle relative to the horizontal plane, so as to adjust the posture of the display device 4 on the conveyor line 3, so as to facilitate subsequent inspection or other operations on the display device 4. The vertical machine device provided in this embodiment is particularly suitable for adjusting the posture of large display devices 4.

[0066] The display device production system includes a conveyor line 3 and a stand device. The conveyor line 3 is provided with a screen support frame 5 for supporting and fixing the display device 4. The display device 4 is mounted on the screen support frame 5. The display device 4 is arranged at a preset acute angle relative to the horizontal plane, and the lower end of the display device 4 is rotatably connected to the screen support frame 5. The width direction of the conveyor line 3 is arranged along the first horizontal direction.

[0067] The vertical machine device includes a flipping device 1 and a front blocking device 2, which are respectively arranged on opposite sides of the conveyor line 3; they are used to abut against the back of the display device 4 and drive the display device 4 to flip to a preset angle relative to the horizontal plane; the front blocking device 2 includes a stop mechanism, and the front blocking device 2 includes a stop mechanism, and the vertical machine device includes two stop mechanisms arranged at intervals in the second horizontal direction, each of which can slide along the second horizontal direction so that the two stop mechanisms can be aligned with the two side frames 42 of the display device 4 respectively, and the stop mechanism is used to abut against the front of the display device 4 at a preset tilt angle.

[0068] The stand device provided in this embodiment, by providing a flipping device 1, can drive the display device 4 to flip to a preset angle relative to the horizontal plane through the flipping device 1, thereby realizing automatic flipping of the display device 4, and improving the flipping automation and efficiency of the display device 4; by providing a front blocking device 2, when the front blocking device 2 is flipped into place, the front blocking device 2 can abut against the front face of the display device 4, thereby preventing the display device 4 from flipping over and tipping over, and improving the flipping safety of the display device 4; at the same time, since there are two stopper mechanisms, and they can respectively face the two side frames 42 of the display device 4, the stopper mechanisms abut against the side frames 42 of the display device 4, and do not contact the screen body 41, effectively avoiding the stopper mechanisms from causing damage to the screen body 41 of the display device 4, and further improving the flipping safety of the display device 4; at the same time, the flipped display device 4 can be clamped between the flipping device 1 and the front blocking device 2, and stably maintained in the flipped state, without the need to manually support the display device 4 after flipping, and the front blocking device 2 will not cause shielding to the screen of the display device 4, and effectively realize the subsequent test operation of the display device 4.

[0069] Preferably, in this embodiment, two front blocking devices 2 are provided, and the two front blocking devices 2 are spaced apart in the second horizontal direction, and each front blocking device 2 includes a stop mechanism, thereby reducing the size of each front blocking device 2, improving the convenience of setting the front blocking device 2, so that the positions of the two stop mechanisms can be adaptively set according to the width of the display device 4, improving the versatility of the front blocking device 2, and making the stand device more suitable for flipping a display device 4 with a larger size. In other embodiments, only one front blocking device 2 may be provided, and one front blocking device 2 includes two stop mechanisms spaced apart in the second horizontal direction.

[0070] It is worth noting that, in this embodiment, the structure of the conveyor line 3 and the screen support frame 5 can adopt the existing structure. This embodiment only describes the structure of the flipping device 1 and the front blocking device 2 in detail, and does not repeat or limit the structure of the conveyor line 3 and the screen support frame 5.

[0071] In this embodiment, the first horizontal direction is perpendicular to the second horizontal direction. In other embodiments, the first horizontal direction and the second horizontal direction are also set at a preset angle. It is sufficient to ensure that the flipping device 1 and the front blocking device 2 are respectively located on opposite sides of the conveyor line 3 and the flipping device 1 can act on the back side of the display device 4 and the front blocking device 2 can act on the side frame 42 of the display device 4.

[0072] like Figures 3 to 5 As shown, the flipping device 1 includes a flipping mechanism, which includes a push unit 13 and a flipping drive 15. The push unit 13 has an abutment component 132 for abutting the display device 4. The push unit 13 can slide along a first horizontal direction to make the abutment component 132 contact or separate from the display device 4. The flipping drive 15 is used to drive the push unit 13 to rotate around an axis extending along a second horizontal direction.

[0073] By setting the push unit 13 to slide along the second horizontal direction, the push unit 13 can be moved horizontally to the position where the contact part 132a contacts the display device 4 before the flip mechanism drives the display device 4 to flip, and then the display device 4 can be driven to rotate by the rotation of the push frame 131. That is, in the initial state, the flip device 1 and the display device 4 are separated, thereby preventing the setting of the flip device 1 from interfering with the transmission of the display device 4 on the conveyor line 3, and ensuring that the display device 4 can be transmitted to the right position.

[0074] Further, the flipping device 1 includes a frame 11 and an adjustment seat 12, the adjustment seat 12 can be slidably mounted on the frame 11 along a first horizontal direction, the push unit 13 can be rotatably mounted on the adjustment seat 12 around a second horizontal direction, and the flipping drive member 15 is mounted on the adjustment seat 12 and connected to the push unit 13. The arrangement of the frame 11 and the adjustment seat 12 and the arrangement of the frame 11 can raise the height of the adjustment seat 12 and the flipping mechanism, thereby enabling the flipping mechanism to be better arranged opposite to the display device 4 located on the conveyor line 3, and reducing the size of the flipping mechanism.

[0075] In other embodiments, the frame 11 may also be able to move relative to the ground along the first horizontal direction, and the flip mechanism is rotatably disposed at the upper end of the frame 11. The frame 11 may also be self-propelled and may also be moved by manual pushing of an operator.

[0076] The frame 11 includes a frame bottom plate 111, a plurality of support columns 113 vertically arranged on the frame bottom plate 111, and a frame top plate 112 connected to the upper ends of the support columns 113. Four support columns 113 are provided, and the four support columns 113 are distributed in a rectangular shape, thereby simplifying the structure of the frame 11. The frame 11 also includes a plurality of support legs 114 connected to the frame bottom plate 111. The support legs 114 are preferably distributed in a rectangular shape, and the height of the support legs 114 can be adjusted to fine-tune the height of the flip mechanism.

[0077] It is worth noting that the structure of the above-mentioned frame 11 is an exemplary structure, and any existing frame 11 structure capable of installing a flip mechanism and an adjustment seat 12 on the frame 11 can be applied to this embodiment, and this embodiment does not limit the structure of the frame 11.

[0078] In this embodiment, in order to realize the automatic movement of the adjustment seat 12, the flip device 1 also includes a translation drive assembly 16, and the translation drive assembly 16 is used to drive the adjustment seat 12 to move along the first horizontal direction. In this embodiment, the translation drive assembly 16 includes a translation piston cylinder, and the translation piston cylinder includes a fixed cylinder body and a piston rod. The fixed cylinder body is installed on the frame top plate 112, and the piston rod extends along the first horizontal direction and is connected to the adjustment seat 12. The extension and retraction of the telescopic rod 151 along the first horizontal direction can drive the adjustment seat 12 to move along the first horizontal direction.

[0079] In another embodiment, the translation drive assembly 16 may also adopt other structures, such as the translation drive assembly 16 includes a rotary motor, a lead screw connected to the driving shaft of the rotary motor, and a nut sleeved on the lead screw, the lead screw extends along the second horizontal direction and is rotatably mounted on the frame 11, the nut is connected to the adjustment seat 12, and a sliding limit structure is provided between the adjustment seat 12 and the frame 11 to limit the adjustment seat 12 to slide only along the first horizontal direction. In another embodiment, the translation drive assembly 16 may also adopt a push rod motor, the driving end of the push rod motor is connected to the adjustment seat 12 to drive the adjustment seat 12 to move along the first horizontal direction. It is worth noting that other existing drive structure forms that can realize the translation of the adjustment seat 12 can be applied to this embodiment, and this embodiment does not limit the specific structure of the translation drive assembly 16.

[0080] Furthermore, the adjustment seat 12 includes a sliding plate 121 and a driving block 123 connected to the bottom of the sliding plate 121, and the driving block 123 is connected to the piston rod. The sliding plate 121 is preferably spaced apart from the frame top plate 112, the translation drive assembly 16 is located between the sliding plate 121 and the frame top plate 112, and the flip mechanism is installed on the upper side of the sliding plate 121 to provide space for the installation of the translation drive assembly 16, and avoid interference between the translation drive assembly 16 and the flip mechanism, thereby improving the rationality of the spatial layout.

[0081] It is understandable that in other embodiments, the translation drive assembly 16 may not be provided, that is, the adjustment seat 12 is moved by manual pushing of an operator.

[0082] In order to improve the reliability of the sliding of the adjustment seat 12, preferably, the flip device 1 also includes a sliding guide assembly 17, which is used to guide the sliding of the adjustment seat 12 along the first horizontal direction. In this embodiment, the sliding guide assembly 17 is installed between the sliding plate 121 and the frame top plate 112, and the sliding guide assembly 17 includes a guide rail 171 laid on the frame top plate 112 along the first horizontal direction and a guide shaft 172 slidably inserted into the guide rail 171. The adjustment seat 12 also includes an adapter seat 122, which is connected to the guide shaft 172. In other embodiments, the sliding guide assembly 17 may include a slide rail extending along the first horizontal direction and a slider slidably arranged on the slide rail, one of the slide rail and the slider is connected to the frame top plate 112, and the other is connected to the sliding plate 121.

[0083] Furthermore, at least two adapter seats 122 are provided at intervals along the length direction of the guide shaft 172 to improve the guiding reliability and improve the force balance and operation reliability of the adjustment seat 12 during the sliding process. Preferably, adapter seats 122 are provided at both ends of the guide shaft 172, and the two adapter seats 122 are respectively located at both ends of the sliding plate 121 along the first horizontal direction.

[0084] Preferably, the guide rail 171 is a linear bearing to reduce the friction between the guide rail 171 and the guide shaft 172. Preferably, two sliding guide assemblies 17 are arranged at intervals along the first horizontal direction, and the translation drive assembly 16 is arranged between the two sliding guide assemblies 17 to further improve the force balance and sliding reliability of the adjustment seat 12.

[0085] In order to limit the sliding stroke of the adjustment seat 12, the flip device 1 also includes a sliding limit assembly. In this embodiment, the sliding limit assembly includes a limit block 182 and a hydraulic buffer 181. When the adjustment seat 12 extends outward by a preset stroke, the limit block 182 abuts against the hydraulic buffer 181 to limit the adjustment seat 12 from continuing to slide forward. At the same time, the hydraulic buffer 181 can provide buffering when contacting the limit block 182 to reduce vibration during contact. It is worth noting that the structure of the above-mentioned sliding limit assembly is only an exemplary structure. Other existing structures that can achieve sliding limit can be applied to this embodiment. For example, the sliding limit assembly can use an elastic pad to contact the limit block 182 to achieve limit buffering, etc. This embodiment does not specifically limit the specific form of the sliding limit assembly.

[0086] Furthermore, the flipping device 1 further includes a shielding plate 19, which is provided on both sides of the sliding plate 121 along the second horizontal direction, and is used to shield the lateral gap between the sliding plate 121 and the frame top plate 112, so that the sliding guide assembly 17 and the translation drive assembly 16 can be located between the two shielding plates 19, reducing the probability of dust, impurities, etc. acting on the sliding guide assembly 17 and the translation drive assembly 16, improving the smoothness and reliability of the operation of the translation drive assembly 16 and the sliding guide assembly 17, and improving the appearance of the flipping device 1. The shielding plate 19 is detachably connected to the sliding plate 121 or the frame top plate 112.

[0087] In this embodiment, the shielding plate 19 is detachably connected to the frame top plate 112, thereby reducing the load of the translation drive assembly 16. The shielding plate 19 includes a baffle portion, which is perpendicular to the second horizontal direction and connected to the frame top plate 112 at the lower end. Both sides of the baffle portion along the first horizontal direction are folded inward to form side flange portions, and the upper end of the baffle portion is folded inward to form an upper flange portion, and the sliding plate 121 is located at the lower side of the upper flange portion. An extension plate portion is also protruding downward on the lower side of the baffle portion, and the extension plate portion is detachably connected to the support column 113 to ensure the installation reliability of the shielding plate 19 on the frame 11.

[0088] like Figure 3 and Figure 5 As shown, the push unit 13 includes a push frame 131, the lower end of which is rotatably mounted on the adjustment seat 12 via a mounting shaft 133, and a contact component 132 is detachably mounted on the push frame 131 and protrudes from the side of the push frame 131 facing the front blocking device 2. By arranging the push frame 131 and the contact component 132 to be detachably connected, the push frame 131 and the contact component 132 can be made of different materials, thereby improving the flexibility of setting the push unit 13, and facilitating replacement of the contact component 132 after the contact component 132 is worn or damaged, thereby improving the convenience of replacement of the contact component 132; at the same time, the contact component 132 protrudes from the side of the push frame 131 facing the front blocking device 2, so that when the contact component 132 contacts the back of the display device 4, the push frame 131 will not contact the display device 4, thereby preventing the push frame 131 from scratching the display device 4.

[0089] Furthermore, the adjustment seat 12 includes two hinged seats 124 that are opposite and spaced apart along the second horizontal direction. The two hinged seats 124 are installed on the upper end surface of the sliding plate 121 , both ends of the mounting shaft 133 are installed on the two hinged seats 124 , and the push frame 131 is located between the two hinged seats 124 .

[0090] The abutment component 132 includes a lower abutment component 132a and an upper abutment component 132b, the lower abutment component 132a is sleeved on the mounting shaft 133, and the upper abutment component 132b is installed on the top of the push frame 131; in the first horizontal direction, the distance between the lower abutment component 132a and the front blocking device 2 is smaller than the distance between the upper abutment component 132b and the front blocking device 2.

[0091] The arrangement of the upper abutting component 132b and the lower abutting component 132a ensures that when the flipping mechanism drives the display device 4 to rotate, both the upper abutting component 132b and the lower abutting component 132a are in contact with the back side of the display device 4, ensuring that the flipping device 1 has at least two contact positions with the back side of the display device 4 in the height direction of the display device 4, thereby improving the force balance and flipping stability of the display device 4 during the flipping process; at the same time, the lower abutting component 132a is sleeved on the mounting shaft 133, so that during the rotation of the push frame 131, the lower abutting component 132a always maintains a state of abutting with the display device 4, which can effectively prevent the display device 4 from sliding during the flipping process, thereby improving the flipping reliability and stability of the display device 4.

[0092] The lower abutting component 132a is preferably made of an elastic material, which may be, but is not limited to, silicone or rubber, etc., to avoid a hard collision between the lower abutting component 132a and the display device 4, thereby reducing the probability of the display device 4 being squeezed and damaged. The lower abutting component 132a is preferably rotatably sleeved on the mounting shaft 133, so that the friction between the lower abutting component 132a and the back of the display device 4 is rolling friction, thereby reducing the wear of the lower abutting component 132a on the display device 4.

[0093] The upper abutting component 132b is preferably made of elastic material to prevent the upper abutting component 132b from hard collision with the back of the display device 4 and causing damage to the display device 4. Preferably, the upper abutting component 132b is preferably a sleeve, roller or roller structure, and the extension direction of the upper abutting component 132b is the same as the extension direction of the installation shaft 133, so as to simplify the structure of the upper abutting component 132b and improve the installation convenience of the upper abutting component 132b on the push frame 131. In other embodiments, the upper abutting component 132b can also be a strip structure or a block structure.

[0094] Since the position of the upper abutting component 132b relative to the display device 4 changes when the abutting frame 131 drives the display device 4 to flip, in order to reduce the friction between the upper abutting component 132b and the display device 4, preferably, the upper abutting component 132b is installed on the abutting frame 131 so as to be rotatable around its own axis, and the rotation axis of the upper abutting component 132b is arranged along the second horizontal direction. Therefore, when the upper abutting component 132b pushes the display device 4 to rotate, the friction between the upper abutting component 132b and the display device 4 is rolling friction, and the friction is reduced, effectively avoiding the problem of wear of the display device 4 caused by excessive friction applied by the upper abutting component 132b to the display device 4.

[0095] Preferably, the plane where the center line of the upper abutting part 132b and the center line of the lower abutting part 132a are located is spaced apart from the abutting frame 131, and the abutting frame 131 is located on the side of the plane away from the front blocking device 2, so that when the upper abutting part 132b is rotated to contact with the display device 4, only the upper abutting part 132b and the lower abutting part 132a abut against the display device 4, and the abutting frame 131 is spaced apart from the display device 4. Therefore, while ensuring the supporting stability of the flipping mechanism for the display device 4, it is possible to avoid the problem that the upper abutting part 132b or the lower abutting part 132a may not be able to contact the display device 4 due to the contact between the abutting frame 131 and the display device 4, thereby ensuring the contact reliability of the upper abutting part 132b and the lower abutting part 132a with the display device 4 and reducing the processing accuracy requirements for the abutting frame 131.

[0096] In order to improve the installation convenience of the upper abutting component 132b and the lower abutting component 132a, preferably, the push-pushing frame 131 includes two swing arms 1311 that are opposite and spaced apart in the first horizontal direction, the mounting shaft 133 is rotatably arranged through the lower ends of the two swing arms 1311, and the upper abutting component 132b is connected between the upper ends of the two swing arms 1311. Specifically, a connecting shaft 1314 is connected between the upper ends of the two swing arms 1311, and the upper abutting component 132b is rotatably sleeved on the connecting shaft 1314. This arrangement can simplify the structure of the push-pushing frame 131, reduce the weight of the push-pushing frame 131, and facilitate the arrangement of the mounting shaft 133 and the connecting shaft 1314 while ensuring the structural strength and rigidity of the push-pushing frame 131.

[0097] The swing arm 1311 preferably includes a first arm portion 13111 and a second arm portion 13112, the first arm portion 13111 extends obliquely from bottom to top in a direction away from the front blocking device 2, the lower end of the second arm portion 13112 is connected to the upper end of the first arm portion 13111, the second arm portion 13112 extends vertically from bottom to top or tilts from bottom to top in a direction close to the front blocking device 2, the second arm portion 13112 is set at a preset obtuse angle with the first arm portion 13111, and the connecting shaft 1314 is installed at the upper end of the second arm portion 13112. This arrangement can reduce the distance between the upper abutting part 132b and the lower abutting part 132a in the first horizontal direction under the premise that the distance between the lower abutting part 132a and the upper abutting part 132b in the vertical direction remains unchanged, thereby reducing the flipping angle required for the push frame 131 when the upper abutting part 132b flips from the initial state to abut against the display device 4, thereby improving the driving efficiency; at the same time, this arrangement can increase the angle between the plane where the central axis of the installation shaft 133 and the connecting shaft 1314 is located and the plane where the two first arm parts 13111 are located, thereby effectively avoiding contact between the push frame 131 and the display device 4.

[0098] In order to better ensure the overall structural rigidity of the push-resistance frame 131, a connecting rod 1313 is further connected between the two swing arms 1311. The connecting rod 1313, the connecting shaft 1314 and the installation shaft 133 are all arranged at intervals, thereby improving the integrity of the push-resistance frame 131 and reducing the probability of deformation of the two swing arms 1311. In this embodiment, one connecting rod 1313 is provided and extends along the extension direction of the installation shaft 133. In other embodiments, two or more connecting rods 1313 may also be arranged at intervals along the extension direction of the swing arms 1311.

[0099] The push-pushing frame 131 further includes a connecting plate 1312, which is connected between the two swing arms 1311, the lower end of the connecting plate 1312 extends to the lower abutting part 132a, and the upper end of the connecting plate 1312 extends to the vicinity of the second arm 13112. The provision of the connecting plate 1312 can further improve the structural integrity and structural rigidity of the push-pushing frame 131, and can shield the structure of the connecting plate 1312 away from the front blocking device 2, thereby preventing the structure on the conveyor line 3 from causing collision with the flip driving member 15, and improving the safety and reliability of the flip driving member 15.

[0100] The flip driving member 15 preferably includes a piston cylinder, which includes a cylinder body and a telescopic rod 151 that can be extended and retracted relative to the cylinder body. The fixed end of the cylinder body is hinged on the adjustment seat 12, and the end of the telescopic rod 151 is hinged to the push frame 131. The piston cylinder extends from bottom to top in the direction toward the push frame 131. Therefore, when the telescopic rod 151 is extended, the telescopic rod 151 pushes the push frame 131 to rotate in the direction toward the front blocking device 2, so that the upper abutting component 132b can rotate in the direction close to the display device 4 until it contacts the display device 4, and after the upper abutting component 132b contacts the display device 4, the continued rotation of the push frame 131 synchronously drives the display device 4 to rotate; when the telescopic rod 151 is retracted, it drives the push frame 131 to rotate along the side away from the front blocking device 2 to reset to the initial state.

[0101] In this embodiment, the telescopic rod 151 is hinged with the connecting rod 1313, and the axis of the hinge is the axis of the connecting rod 1313, so as to simplify the connection structure between the flip driving member 15 and the push frame 131 and improve the convenience of assembly. Further, a bearing member 152 is rotatably sleeved on the connecting rod 1313, and the bearing member 152 is connected to the telescopic rod 151. The bearing member 152 is a joint bearing, a fisheye bearing or a universal ball bearing, etc., so as to improve the convenience of connection between the bearing member 152 and the telescopic rod 151. Further, an avoidance opening is opened on the connecting plate 1312, and the bearing member 152 is arranged opposite to the avoidance opening to avoid interference between the bearing member 152 and the connecting plate 1312.

[0102] like Figure 5 and Figure 6 As shown, preferably, the flipping device 1 further includes a rotation limiting assembly 14 , and the rotation limiting assembly 14 is used to limit the rotation angle of the push unit 13 , thereby ensuring the flipping reliability and safety of the display device 4 .

[0103] In this embodiment, the rotation limit assembly 14 includes a limit seat 141, a limit rod 142 and a limit shaft 143. The limit seat 141 is installed on the adjustment seat 12 and is located on the side of the push unit 13 away from the front blocking device 2. The limit seat 141 is provided with a limit groove 1411 extending along the second horizontal direction; the limit rod 142 is inclined from bottom to top toward the direction close to the front blocking device 2, and the upper end of the limit rod 142 is hinged to the push unit 13; the limit shaft 143 is connected to the lower end of the limit rod 142, and the limit shaft 143 is slidably inserted in the limit groove 1411.

[0104] From the above, when the push frame 131 flips over toward the front blocking device 2, the lower end of the limit rod 142 moves with the push frame 131 in the direction away from the limit seat 141, thereby driving the lower end of the limit rod 142 and the limit shaft 143 to slide in the direction toward the front blocking device 2, that is, the limit shaft 143 slides in the limit groove 1411, and when the limit shaft 143 slides to abut against the groove end wall of the limit groove 1411, the limit rod 142 cannot continue to move relative to the limit seat 141, that is, the push frame 131 cannot continue to rotate in the direction toward the front blocking device 2, thereby limiting the maximum inclination angle of the push frame 131; similarly, when the limit shaft 143 abuts against the groove end wall of the limit groove 1411 away from the mounting shaft 133, the push frame 131 has a minimum inclination angle relative to the adjustment seat 12.

[0105] That is, the structural setting of the above-mentioned rotation limit assembly 14 can limit the rotation stroke of the push frame 131 by the length of the limit groove 1411; at the same time, the structural setting of the above-mentioned rotation limit assembly 14 makes the structure of the rotation limit assembly 14 all located on the side of the connecting plate 1312 away from the front blocking device 2, which can avoid the rotation limit assembly 14 from colliding with the display device 4, and improve the layout rationality and convenience of the rotation limit assembly 14; furthermore, the setting of the above-mentioned rotation limit assembly 14 can also play a supporting role for the push frame 131, increase the force stability and reliability of the push frame 131 during the rotation process, and improve the structural stability of the push frame 131.

[0106] In other embodiments, other structures for limiting the rotational travel of the push frame 131 may also be provided. For example, an arc-shaped limiting arc groove may be provided on the hinge seat 124, and a limiting protrusion may be provided on the swing arm 1311. The limiting protrusion is slidably inserted in the limiting arc groove, thereby achieving rotational limitation of the swing arm 1311 relative to the hinge seat 124, that is, achieving rotational limitation of the push frame 131.

[0107] The limiting rod 142 preferably includes a rod body 1421 and hinges 1422 connected to both ends of the rod body 1421. The hinges 1422 are bearing structures, wherein the inner ring of one hinge 1422 is inserted with a hinge shaft 144, and the inner ring of the other hinge 1422 is inserted with the above-mentioned limiting shaft 143. Both the hinge shaft 144 and the limiting shaft 143 extend along the second horizontal direction, and the hinge shaft 144 is mounted on the push-resisting frame 131. This structure of the limiting rod 142 is easy to realize the hinge connection between the limiting rod 142 and the limiting shaft 143 and the push-resisting frame 131, and improves the smoothness of the limiting rod 142 rotating relative to the push-resisting frame 131 and the smoothness of the sliding relative to the limiting seat 141.

[0108] Preferably, two rotation limit assemblies 14 are provided, and the two rotation limit assemblies 14 are respectively provided corresponding to the two swing arms 1311, so as to improve the force balance and rotation reliability of the push frame 131 when rotating. At the same time, the two rotation limit assemblies 14 can support the two swing arms 1311, and improve the structural stability of the push frame 131 when rotating. Furthermore, a mounting cavity is provided on the side of the swing arm 1311 away from the connecting plate 1312, and the hinge shaft 144 is connected to the cavity walls on both sides of the mounting cavity, thereby improving the installation convenience of the hinge shaft 144 on the push frame 131.

[0109] Preferably, the hinge 1422 includes a bearing portion and a rod portion connected to the outer wall of the bearing portion, the bearing portion is connected to the hinge shaft 144 or the limit shaft 143, and the rod portion extends coaxially with the rod body 1421 and is threadedly connected, thereby being able to adjust the total length of the limit rod 142, thereby adjusting the minimum inclination angle and the maximum inclination angle of the thrust unit 13 on the basis of keeping the groove length of the limit groove 1411 unchanged, thereby being able to improve the applicability of the rotation limit assembly 14.

[0110] The limiting seat 141 is provided with an installation groove with an upper opening, and the installation groove is provided with limiting grooves 1411 on the groove walls on the opposite sides in the second horizontal direction, and the lower end of the corresponding hinge 1422 extends out of the installation groove, and the two ends of the limiting shaft 143 are slidably arranged in the two limiting grooves 1411, so as to improve the reliability of the matching between the limiting shaft 143 and the limiting groove 1411. The limiting shaft 143 preferably includes a main shaft portion and an anti-slip portion, the main shaft portion is inserted into the two limiting grooves 1411, and one end of the main shaft portion away from the anti-slip portion is detachably connected to the limiting member, and the anti-slip portion and the limiting member are both located outside the limiting seat 141 and are restricted from passing through the limiting groove 1411. In this way, the assembly convenience of the limiting shaft 143, the limiting seat 141 and the bearing member 152 can be improved.

[0111] Furthermore, if Figure 3 As shown, the flipping device 1 also includes two side baffles 110 that are opposite and spaced apart. The two side baffles 110 are respectively located on the opposite sides of the push frame 131 along the second horizontal direction, and the two side baffles 110 and the push frame 131 together form a shielding space. The shielding space is located on the side of the push unit 13 away from the front blocking device 2, the rotation limit assembly 14 is located in the shielding space, and the flipping drive member 15 is at least partially located in the shielding space, thereby enabling the two side baffles 110 to laterally shield the flipping drive member 15 and the rotation limit assembly 14, thereby improving the aesthetic appearance of the flipping device 1 and improving the reliability of the flipping device 1.

[0112] The side baffle 110 includes a side plate portion, the lower end of which is bent to form a lower folding edge portion, and the lower folding edge portion is attached to and detachably connected to the sliding plate 121. The side plate portion has an inclined side edge extending from top to bottom away from the conveyor line 3, and the inclined side edge is folded inward to form a front folding edge portion. When the turning device 1 is in the initial state, the front folding edge portion is parallel to the connecting plate 1312 to improve the overall appearance of the turning device 1.

[0113] like Figure 7 and Figure 8 As shown, the front blocking device 2 further includes a mounting frame 21, and the stop mechanism includes a sliding frame 22 and a stop assembly 23. The sliding frame 22 can be slidably mounted on the mounting frame 21 along the second horizontal direction, and the stop assembly 23 is mounted on the sliding frame 22 and located above the mounting frame 21. The stop assembly 23 is used to abut against the frame of the display device 4. Therefore, the position of the stop assembly 23 in the second horizontal direction can be adjusted by sliding the sliding frame 22 relative to the mounting frame 21 along the second horizontal direction, so that the stop assembly 23 can be aligned with the frame of the display device 4, so that the stand device can be suitable for the use of display devices 4 of different models and sizes, thereby improving the versatility of the stand device and reducing the use cost of the stand device.

[0114] In this embodiment, the mounting frame 21 includes two mounting side plates 212 that are opposite and spaced apart in the second horizontal direction and a mounting main plate 211 connected between the bottom ends of the two mounting side plates 212. The mounting main plate 211 is perpendicular to the first horizontal direction, and the stop mechanism is slidably mounted on the mounting main plate 211. A reinforcing plate 216 is preferably connected between the mounting main plate 211 and the two mounting side plates 212 to reduce the probability of deformation of the mounting main plate 211.

[0115] The mounting frame 21 also includes a mounting base plate 213 connected between the bottom ends of the two mounting side plates 212. The mounting main board 211 and the mounting base plate 213 are spaced apart so that the mounting main board 211, the mounting base plate 213 and the two mounting side plates 212 form an installation space. The front blocking device 2 also includes a stop controller 210, and the stop controller 210 is installed in the installation space to avoid interference between the stop controller 210 and the stop mechanism.

[0116] The mounting frame 21 further includes a mounting back plate 214, which is connected between the two mounting side plates 212 and connected at its lower end to the mounting bottom plate 213. The mounting back plate 214 is located on a side of the stop controller 210 away from the flip mechanism to provide shielding and protection for the stop controller 210. The mounting back plate 214 and the mounting main plate 211 are spaced apart in the first horizontal direction, and the side of the mounting side plate 212 away from the flip device 1 is flush with the mounting back plate 214 to prevent the structure mounted on the mounting main plate 211 from being collided with an external structure, thereby improving the safety of the front blocking device 2.

[0117] In order to improve the docking reliability and stability between the front blocking device 2 and the conveyor line 3, a docking fixing seat 215 is connected to the side of the installation main board 211 facing the flipping device 1, and two docking fixing seats 215 are arranged at intervals along the second horizontal direction. One end of the docking fixing seat 215 is connected to the installation main board 211, and the other end is used to connect to the conveyor line 3.

[0118] In order to improve the reliability and smoothness of the sliding of the stop mechanism along the second horizontal direction, the front blocking device 2 also includes a sliding guide assembly 25. In this embodiment, the sliding guide assembly 25 includes a guide rail 251 installed on the mounting main board 211 along the second horizontal direction and a guide slider 252 slidably arranged on the guide rail 251, and the guide slider 252 is connected to the sliding frame 22. In other embodiments, the sliding guide assembly 25 can also adopt other existing structures that can achieve sliding guidance, such as a structure of a linear bearing and a guide rod, etc. The present invention does not limit the structure of the sliding guide assembly 25. It is preferred that two sliding guide assemblies 25 are arranged at intervals along the vertical direction to improve the force stability and operation reliability of the stop mechanism.

[0119] In order to realize the automatic sliding of the stop mechanism along the second horizontal direction, the front blocking device 2 also includes a sliding drive assembly 24, which is used to drive the stop mechanism to slide along the second horizontal direction. Preferably, the sliding guide assembly 25 and the sliding drive assembly 24 are respectively located on opposite sides of the mounting main board 211 to improve the rationality of the spatial layout and reduce the probability of interference between the structures. In this embodiment, the sliding guide assembly 25 is located on the side of the mounting main board 211 away from the flipping device 1. In other embodiments, the sliding drive assembly 24 may also be located on the side of the mounting main board 211 away from the flipping device 1.

[0120] The sliding frame 22 is arranged on a side of the mounting main board 211 away from the sliding drive assembly 24 to reduce the probability of interference between the sliding frame 22 and the display device 4 and the conveyor line 3, and to provide sufficient space for the arrangement of the sliding drive assembly 24. In order to improve the connection convenience between the sliding frame 22 and the sliding drive assembly 24, a long strip opening 2111 is provided on the mounting main board 211, and the long strip opening 2111 extends along the first horizontal direction. The sliding frame 22 has a driving connection member 224, and the driving connection member 224 is passed through the long strip opening 2111 and connected to the sliding drive assembly 24. Preferably, the two sliding guide assemblies 25 are respectively located on the upper and lower sides of the long strip opening 2111.

[0121] like Figure 8 and Fig. 9As shown, in this embodiment, the sliding drive assembly 24 includes a driving motor 241, a transmission screw 242 and a nut seat 243. The transmission screw 242 extends along the second horizontal direction and is rotatably mounted on the mounting main board 211. The driving motor 241 is used to drive the transmission screw 242 to rotate. The nut seat 243 is screwed on the transmission screw 242, and the nut seat 243 is connected to the driving connector 224. Therefore, when the driving motor 241 drives the transmission screw 242 to rotate, the nut seat 243 moves along the extension direction of the transmission screw 242, thereby driving the stop mechanism to move along the second horizontal direction.

[0122] Furthermore, the mounting main board 211 is provided with at least two shaft seats spaced apart along the second horizontal direction, and the transmission screw 242 is rotatably passed through the shaft seats. The transmission screw 242 includes a screw segment and an optical axis segment coaxially connected to both ends of the screw segment, and two shaft seats are provided, and the two optical axis segments are rotatably passed through the two shaft seats. Preferably, a rotating bearing is provided between the optical axis segment and the rotating shaft.

[0123] The sliding drive assembly 24 further includes a transmission assembly 244, which is connected between the transmission screw 242 and the drive motor 241 to transmit the driving force of the drive motor 241 to the transmission screw 242, and reduce the requirements for the installation position of the drive motor 241, thereby improving the layout convenience of the drive motor 241 on the mounting frame 21. In other embodiments, the drive shaft of the drive motor 241 can also be directly connected to one end of the transmission screw 242.

[0124] In this embodiment, the transmission assembly 244 further includes a driving pulley 2441 sleeved on the driving shaft of the driving motor 241, a driven pulley 2442 sleeved on an optical axis segment, and a transmission belt 2443 wound around the driving pulley 2441 and the driven pulley 2442. That is, the transmission assembly 244 adopts a belt drive. In other embodiments, the transmission assembly 244 may also adopt a gear drive or a chain drive structure, and the gear drive structure and the chain drive structure are both existing relatively conventional drive structures, which will not be described in detail in the present invention.

[0125] like Figures 8 to 10 As shown, in order to better control the running stroke of the stop mechanism, in this embodiment, the front blocking device 2 further includes a position detection component 26, which is used to detect the position of the stop mechanism relative to the mounting frame 21 in the second horizontal direction. In this embodiment, the position detection component 26 includes a position sensor 261 and a sensing member 262 used in conjunction with each other, one of the position sensor 261 and the sensing member 262 is installed on the sliding frame 22 of the stop mechanism, and the other is installed on the mounting main board 211, and the position sensor 261 can be triggered by the sensing member 262 when it is close to or abuts against the sensing member 262, thereby realizing the position detection of the stop mechanism.

[0126] In this embodiment, the position sensor 261 is mounted on the mounting main board 211, and the sensing member 262 is mounted on the stop mechanism. Preferably, the position sensor 261 is located on a side of the mounting main board 211 away from the sliding frame 22 to avoid interference between the position sensor 261 and the sliding frame 22, and the sensing member 262 is mounted on the driving connection member 224.

[0127] At least two position sensors 261 are arranged at intervals along the second horizontal direction, that is, the position detection component 26 includes at least two limit position sensors 261a, and the two limit position sensors 261a are respectively used to detect the two limit positions that the stop mechanism can reach, that is, the sliding drive component 24 drives the stop mechanism to move between the two limit positions. In this embodiment, three position sensors 261 are arranged, and another position sensor 261 is an origin position sensor 261b, which is located between the two limit position sensors 261a and is used to detect whether the stop mechanism returns to the initial position. The origin position sensor 261b is arranged close to a limit position sensor 261a far away from the other stop mechanism.

[0128] In this embodiment, the position sensor 261 preferably adopts a U-shaped photoelectric sensor, which has a U-shaped detection slot, the opening of the detection slot faces the sensing member 262, and the detection slot is set through in the second horizontal direction. The sensing member 262 can slide into the detection slot with the stop mechanism to block the light in the detection slot, thereby changing the output signal of the position sensor 261. In other embodiments, the position sensor 261 can also adopt a proximity switch or a micro switch.

[0129] Furthermore, in order to enhance the applicability of the front blocking device 2 to display devices 4 of different sizes, the positions of all position sensors 261 in the second horizontal direction relative to the mounting main board 211 can be adjusted, thereby enabling the operating stroke of the stop mechanism in the second horizontal direction to be adjusted by adjusting the distance between the two limit position sensors 261a; and by adjusting the distance between the origin position sensor 261b and the adjacent limit position sensor 261a, it can be ensured that when the display device 4 is transported into place by the conveyor line 3, the stop device in the initial state can be located on the outside of the display device 4 in the second horizontal direction.

[0130] The position detection assembly 26 also includes a slide 264 and a sensor seat 263. The slide 264 extends along the second horizontal direction and is installed on the mounting main board 211. Each position sensor 261 is installed on the slide 264 through the sensor seat 263. The installation position of the sensor seat 263 on the slide 264 can be adjusted in the second horizontal direction, thereby adjusting the position of the position sensor 261 by adjusting the position of the sensor seat 263. Furthermore, an installation slot 2641 is provided on the slide 264 along the second horizontal direction. The sensor seat 263 is connected to the slide 264 through a fastener, and the fastener is slidably arranged in the installation slot 2641, thereby improving the convenience of adjusting the position of the sensor seat 263.

[0131] like Figure 7 and Figure 8 As shown, the sliding frame 22 includes a sliding plate 221 and a sliding rod 222. The sliding plate 221 is opposite to the mounting main board 211 and is arranged at an interval. The sliding plate 221 is slidably mounted on the mounting main board 211. Specifically, the sliding plate 221 is connected to the guide sliders 252 of the two sliding guide assemblies 25. The sliding rod 222 extends from bottom to top, and the lower end of the sliding rod 222 is connected to the sliding plate 221. The stopper assembly 23 is installed on the sliding rod 222 and is located above the mounting frame 21. The width of the sliding rod 222 in the second horizontal direction is smaller than the width of the sliding plate 221 in the second horizontal direction. By providing the sliding rod 222 and the sliding plate 221, the convenience of the sliding connection between the sliding frame 22 and the mounting frame 21 can be improved, and at the same time, the overall size and weight of the sliding frame 22 can be reduced, thereby reducing the cost.

[0132] The driving connector 224 is vertically connected to the sliding plate 221, and the sliding rod 222 is connected to the side of the sliding plate 221 away from the sliding driving assembly 24 to increase the contact area between the sliding rod 222 and the sliding plate 221. The sliding rod 222 and the sliding plate 221 are preferably detachably connected by screws, but in other embodiments, the sliding rod 222 and the sliding plate 221 can also be welded.

[0133] The sliding rod 222 includes a lower rod segment 2221, an inclined rod segment 2222 and an upper rod segment 2223 which are sequentially connected from bottom to top. The lower rod segment 2221 and the upper rod segment 2223 are both vertically arranged. The lower rod segment 2221 is connected to the sliding plate 221. A stop assembly 23 is installed on the upper rod segment 2223. The inclined rod segment 2222 is inclined from bottom to top toward the display device 4. Therefore, when the lower rod segment 2221 is installed on the side of the mounting frame 21 away from the display device 4, the distance between the upper rod segment 2223 and the conveyor line 3 can be shortened, thereby reducing the distance between the stop assembly 23 and the conveyor line 3 and improving the convenience of setting the stop assembly 23.

[0134] like Figure 7 , Figure 8and Fig.11 As shown, the stopper assembly 23 includes a stopper 232 and a stopper driving member 231. The stopper driving member 231 is used to drive the stopper 232 to move along the first horizontal direction so that the stopper 232 abuts against or separates from the display device 4. As a result, when the display device 4 needs to be abutted, the stopper 232 can extend relative to the sliding frame 22 to contact the side frame 42 of the display device 4, thereby avoiding the need for the sliding frame 22 to move as a whole along the first horizontal direction to achieve docking or separation with the display device 4, reducing the driving load of the stopper driving member 231, saving costs, and making it easy to control the movement stroke of the stopper 232 along the first horizontal direction.

[0135] In this embodiment, the stopper assembly 23 further includes a connection seat 233, the stopper 232 is a sleeve, a drum or a roller structure, and the axis of the stopper 232 is arranged along the second horizontal direction, the stopper 232 can be installed on the connection seat 233 so as to rotate around its own axis, and the stopper driving member 231 is connected to the connection seat 233, so that when the stopper 232 contacts the side frame 42 of the display device 4, the friction between the stopper 232 and the side frame 42 is rolling friction, and the friction is reduced, thereby reducing the probability of the stopper 232 wearing the display device 4. The stopper 232 is preferably made of elastic material to avoid the stopper 232 from hard contacting with the display device 4 and causing scratches to the display device 4, thereby improving the stopping safety of the display device 4.

[0136] Furthermore, the stop assembly 23 includes a floating assembly 234, and the stop member 232 can be installed on the connecting seat 233 in a floating manner along the first horizontal direction through the floating assembly 234, so that the side frame 42 and the stop member 232 are in elastic contact, further avoiding a hard collision between the stop member 232 and the side frame 42, and buffering the impact generated when the stop member 232 and the side frame 42 just come into contact, thereby improving the safety and reliability of the flipping of the display device 4.

[0137] The floating assembly 234 includes a floating guide rod 2341, an elastic member 2342 and a support 2343. The floating guide rod 2341 is slidably inserted into the connecting seat 233 along the first horizontal direction. The end of the floating guide rod 2341 facing the flipping device 1 is connected to the support 2343. The floating guide rod 2341 is sleeved with an elastic member 2342. Both ends of the elastic member 2342 abut against the support 2343 and the connecting seat 233. The stop member 232 is installed on the support 2343. The structural setting of this floating component 234 can guide the floating of the stopper 232 through the floating guide rod 2341, thereby improving the reliability and smoothness of the floating of the stopper 232; at the same time, the setting of the elastic member 2342 is conducive to realizing the resetting of the stopper 232 after being pressed to float, thereby improving the continuity of use of the front blocking device 2; at the same time, when the side frame 42 of the display device 4 presses against the stopper 232, the elastic member 2342 is in a compressed state, and the elastic member 2342 applies an elastic force toward the display device 4 to the support 2343, thereby ensuring that the stopper 232 can be reliably pressed against the side frame 42, effectively ensuring the stopping effect of the stopper assembly 23 on the display device 4.

[0138] Furthermore, the floating assembly 234 further includes a guide sleeve 2344, which is fixedly inserted in the connection seat 233 and extends along the first horizontal direction, and the floating guide rod 2341 is slidably inserted in the guide sleeve 2344, thereby reducing the wear on the connection seat 233 and ensuring the reliability of the setting of the floating guide rod 2341. The guide sleeve 2344 is preferably made of wear-resistant material.

[0139] Preferably, two floating guide rods 2341 are arranged at intervals, and the guide sleeves 2344 and the elastic members 2342 are arranged one-to-one with the floating guide rods 2341. All floating guide rods 2341 are connected to the support 2343 and the connecting seat 233 to ensure the force balance and floating reliability of the support 2343 and the stopper 232. In this embodiment, two floating guide rods 2341 are arranged at intervals along the vertical direction.

[0140] The stopper driving member 231 preferably includes a stopper piston cylinder, the cylinder body of the stopper piston cylinder is mounted on the sliding rod 222, and the piston rod end of the stopper piston cylinder is connected to the connecting seat 233. The stopper piston cylinder is preferably a gas cylinder, which is small in size, light in weight, and convenient to set up. In other embodiments, other existing structures that can realize linear drive can also be used, such as an oil cylinder, a push rod motor, a wax motor, a linear motor or other structures.

[0141] It is preferred that a plurality of stopper assemblies 23 are arranged at intervals along the extension direction of the sliding frame 22, so as to increase the contact position between the front blocking device 2 and the side frame 42 of the display device 4, improve the stopping effect on the display device 4, and also reduce the size of each stopper assembly 23. In this embodiment, a plurality of stopper assemblies 23 are arranged at intervals along the extension direction (i.e., the vertical direction) of the upper rod section 2223.

[0142] It can be understood that when the preset angle is 90°, the display device 4 is vertically arranged, and the spacing between the multiple stop members 232 and the sliding rod 222 is the same, that is, the multiple stop members 232 are spaced apart in the vertical direction to achieve multi-point support for the display device 4; if the display device 4 is flipped to the preset angle, when the display device 4 is tilted relative to the vertical plane, each stop member 232 extends at a different distance relative to the sliding rod 222 to ensure that each stop member 232 is in contact with the display device 4.

[0143] In order to achieve automatic alignment between the stop assembly 23 and the frame of the display device 4, in this embodiment, the front blocking device 2 also includes an edge-finding sensor 28, which is used to detect the side edge position of the display device 4. The edge-finding sensor 28 is communicated with the stop controller 210, and the stop controller 210 controls the movement of the sliding drive assembly 24 according to the side edge position detected by the edge-finding sensor 28.

[0144] In this embodiment, when the display device 4 is transported to the position by the conveyor line 3, the two stopper mechanisms are respectively located at the two outer sides of the display device 4 along the second horizontal direction, and the stopper mechanisms are located at the origin relative to the mounting frame 21; when the sliding drive assembly 24 drives the stopper mechanism to slide along the second horizontal direction, the edge-finding sensor 28 performs detection, and when the edge-finding sensor 28 is misaligned with the display device 4 in the second horizontal direction, the edge-finding sensor 28 does not output a signal; when the edge-finding sensor 28 is arranged corresponding to the display device 4 in the second horizontal direction, the cycle sensor outputs a signal. That is, when the edge-finding sensor 28 switches from the state of not outputting a signal to the state of outputting a signal, the edge of the display device 4 is detected.

[0145] The front blocking device 2 further includes a re-judgment sensor 29, which is mounted on the sliding frame 22 and is located on the side of the edge-finding sensor 28 facing the other stop mechanism. The re-judgment sensor 29 is used to detect whether there is a display device 4 on the front side of the stop mechanism, and the re-judgment sensor 29 is in communication connection with the stop controller 210. By providing the re-judgment sensor 29, when both the re-judgment sensor 29 and the edge-finding sensor 28 detect the display device 4, it is determined that there is a display device 4 on the front side of the stop mechanism, which can improve the detection reliability, avoid misjudgment caused by the detection failure of the edge-finding sensor 28, and reduce the probability of misjudgment, thereby improving the operational reliability and safety of the front blocking device 2.

[0146] Furthermore, the front blocking device 2 further includes a backup sensor 230, which is mounted on the sliding frame 22 and is used to detect the side edge of the display device 4. The backup sensor 230 is a backup component of the edge-finding sensor 28, and is activated and used when the edge-finding sensor 28 fails or malfunctions.

[0147] The re-judgment sensor 29, the edge-finding sensor 28, and the backup sensor 230 are preferably reflective photoelectric sensors to achieve contactless detection, thereby ensuring detection reliability and reducing the installation position requirements for the re-judgment sensor 29, the edge-finding sensor 28, and the backup sensor 230. In other embodiments, the re-judgment sensor 29, the edge-finding sensor 28, and / or the backup sensor 230 may also be a micro switch or other existing sensors that can achieve in-place detection.

[0148] In order to prevent the stopper 232 from not contacting the side frame 42 due to the stopper assembly 23 not being aligned with the side frame 42 of the display device 4, thereby causing the display device 4 to flip and fall in a direction away from the flip mechanism, preferably, the front blocking device 2 further includes an anti-tilt member 27, which is mounted on the sliding rod 222 and is located on the side of the stopper assembly 23 facing the other stopper mechanism. In the first horizontal direction, the spacing between the anti-tilt member 27 and the sliding rod 222 is smaller than the spacing between the stopper 232 and the sliding rod 222, and the anti-tilt member 27 extends along the second horizontal direction.

[0149] By setting the anti-roll member 27, when the stop member 232 is in normal contact with the side frame 42 of the display device 4, since the anti-roll member 27 is closer to the sliding rod 222 than the stop member 232, the anti-roll member 27 is spaced apart from the display device 4, i.e., the anti-roll member 27 is prevented from contacting the display device 4 when the stop assembly 23 is in a normal stopping state; when the stop member 232 is facing the outer side of the side frame 42, if the display device 4 is flipped along the side away from the flipping device 1, the anti-roll member 27 can contact the display device 4 to prevent the display device 4 from continuing to tip over, thereby improving the rotation safety and reliability of the display device 4.

[0150] The anti-dumping member 27 can rotate around its own axis and is mounted on the sliding frame 22, so that the friction between the anti-dumping member 27 and the display device 4 is rolling friction, thereby avoiding scratching the display device 4. The anti-dumping member 27 is preferably made of elastic materials such as rubber or silicone. At least two anti-dumping members 27 are preferably arranged at intervals in the vertical direction to increase the contact position with the display device 4 and improve the reliability of anti-dumping the display device 4. The anti-dumping member 27 can adopt a drum-type structure or a roller-type structure.

[0151] In order to improve the installation convenience of the anti-dumping member 27, an adapter plate 220 is installed on one side of the sliding rod 222, and the anti-dumping member 27 is installed on the adapter plate 220. Therefore, the spacing between the anti-dumping member 27 and the sliding rod 222 can be controlled by setting the size of the adapter plate 220. Further, the anti-dumping member 27 is arranged in multiple groups at intervals along the vertical direction, each group includes at least two anti-dumping members 27 arranged at intervals along the vertical direction, and each group of anti-dumping members 27 is correspondingly provided with an adapter plate 220 to reduce the number of adapter plates 220. Preferably, each group of anti-dumping members 27 is located between two adjacent stopper assemblies 23 to improve the rationality of the spatial layout and reduce the probability of interference between the stopper assemblies 23 and the anti-dumping member 27.

[0152] like Figure 7 and Fig.11 As shown, in this embodiment, the sliding rod 222 is preferably a square steel structure, that is, the sliding rod 222 has a cavity. In order to improve the wiring convenience of the stop driving member 231, the upper rod section 2223 of the sliding rod 222 is provided with a wire inlet 2225, and the wire inlet 2225 is preferably arranged in a one-to-one correspondence with the stop driving member 231. The electrical pipeline of the sliding driving member is introduced into the interior of the sliding rod 222 through the wire inlet 2225; the lower rod section 2221 of the sliding rod 222 is provided with a wire outlet 2224, and the electrical pipeline passes through the sliding rod 222 through the wire outlet 2224 and is connected to the stop controller 210 or other structures, so as to improve the wiring standardization and reduce the probability of the electrical pipeline being pulled and damaged.
