[0036] Reference Figure 1 , Figure 2 , respectively showing the three-dimensional schematic diagrams of the present invention connected with the locking device in different directions. As shown in the figure, the multi-angle adjustment component includes a core shaft 110 and an angle adjustment block 120. The multi-angle adjustment component cooperates with the locking device 300 to lock.

[0037] Reference Figures 1 to 11 A multi-angle adjustment component includes: a core shaft 110, which has a docking portion 10 and a guide portion 40; an angle adjustment block 120, on which a core shaft hole 80 is provided, the core shaft hole 80 has a matching portion 20 matching the docking portion 10, and the core shaft hole on the end face of the angle adjustment block is provided with a limiting portion 30 arranged around the core shaft hole, the limiting portion has a slot 124, and the limiting portion 30 matches the guide portion 40; the angle adjustment block makes the docking portion 10 and the matching portion 20 match through the movement of the limiting portion 30 on the guide portion 40 to lock the angle adjustment block 120 to rotate circumferentially around the core shaft 110, or makes the docking portion 10 and the matching portion 20 match and separate to unlock the angle adjustment block to rotate circumferentially around the core shaft.

[0038] Thus, the unlocking and locking of the angle adjustment block 120 is more convenient and simple, the manufacturing is simple, the cost is low, and the angle adjustment function is achieved by using fewer parts. The above-mentioned mandrel hole is arranged along the direction of the rotation axis of the angle adjustment block.

[0039] At the limiting part 30 of the core shaft hole 80 of the angle adjustment block 120, at least one elastic resistance member 60 is provided in the radial direction of the angle adjustment block 120, and at least one row of sockets matching with the elastic resistance member is provided on the guide part 40 of the core shaft along the axial direction of the core shaft, and when the elastic resistance member matches with the socket, the limiting part 30 matches with the guide part 40. Specifically, the elastic resistance member 60 here is preferably a ball plunger, and the ball head of the ball plunger can be inserted into or removed from the socket as the angle adjustment block moves on the core shaft, so as to limit the position of the angle adjustment block 120 after rotation.

[0040] At least one elastic resistance member arranged in the radial direction of the angle adjustment block 120 is provided at the mating portion 20 of the core shaft hole 80 of the angle adjustment block 120. When the docking portion 10 and the mating portion 20 match, the elastic resistance member abuts against the docking portion 10. Specifically, the elastic resistance member at this location is preferably a telescopic tongue structure. Through the extension and contraction of the telescopic tongue 50 of the telescopic tongue structure, the telescopic tongue 50 can extend out of the insertion hole 507 and abut against the concave arc surface 101 of the docking portion 10, which serves to limit the position. After the angle adjustment block moves on the core shaft, the telescopic tongue 50 can slide along the concave arc surface 101 to the position of the teeth, and the telescopic tongue 50 abuts against the teeth. When the angle adjustment block 120 is rotated, the elastic insertion between the telescopic tongue 50 and the teeth can provide rotation resistance between the angle adjustment block and the core shaft, so that the angle adjustment block does not rotate at will and has a better hand feel.

[0041] The butt joint 10 and the mating part 20 are polygons with matching cross-sectional dimensions and shapes. Specifically, the cross-sectional dimensions can be regular hexagons or rectangles. When the two are plugged in, they cannot rotate relative to each other, thereby positioning the angle adjustment block 120 on the mandrel 110.

[0042] The matching part of the guide part 40 and the limiting part 30 is a circle with a matching cross-sectional size and shape. When the two are plugged in, they can rotate relative to each other, thereby enabling the angle adjustment block to move on the mandrel.

[0043] The limiting part 30 is a cylindrical body that is arranged at the opening of the core shaft hole and protrudes beyond the surface of the angle adjustment block, and is coaxial with the core shaft hole. At least one slot 124 is recessed at intervals at the end of the cylindrical body. When the slot 124 is docked and locked with the set position on the frame 200, the set position at this time is a protruding part that is convexly set. The protruding part can be a clamping strip 201 on the frame 200. The slot and the protruding part are locked in cooperation, which can further lock the rotation of the angle adjustment block on the core shaft. The cylindrical body is mainly used for the role of limiting guidance. Through the sleeve installation between the cylindrical body and the core shaft, the angle adjustment block and the core shaft have a larger contact area, which plays a certain supporting role on the angle adjustment block on the core shaft, so that the angle adjustment block will not swing relative to the core shaft. The structure between the two is more stable and reliable, and the locking is accurate.

[0044] The limiting part 30 is a plurality of protrusions 125 arranged at intervals around the core shaft hole on the angle adjustment block 120 at the opening of the core shaft hole. The protrusions 125 are arranged to protrude along the axial direction of the core shaft 110, and a slot 124 is formed between adjacent protrusions 125. Specifically, the protrusions 125 can be separate individuals, and multiple protrusions are provided. A slot 124 is formed between each protrusion. The slot 124 is mainly used to be stuck in a set protruding part on the frame 200. The protruding part can be a clip strip 201. When the slot 124 is docked with the set position on the frame 200, the set position at this time is the clip strip 201 set with the protrusion. The slot 124 cooperates with the clip strip 201 to lock, and further the rotation of the angle adjustment block on the core shaft can be locked.

[0045] The limiting part 30 is formed at the opening of the core shaft hole 80, and the ring core shaft hole is arranged on the angle adjustment block at intervals and is concave toward the angle adjustment block, and the concave position forms a slot. At this time, the protruding part on the frame is replaced by an insert that can be inserted into the slot. When the slot and the insert on the frame are connected and locked, the slot and the insert cooperate to lock, which can further lock the rotation of the angle adjustment block on the core shaft.

[0046] The elastic resistance piece is a ball head plunger, and the socket is a recess matched with the ball head of the ball head plunger.

[0047] The elastic resistance member is a telescopic tongue structure, including a telescopic tongue 50, an elastic member 501 for supporting the telescopic tongue 50, and a limit column arranged perpendicular to the moving direction of the telescopic tongue 50. The telescopic tongue 50 is provided with a limit groove 503, and the limit column is inserted in the limit groove 503 to limit the range of jumping of the telescopic tongue 50.

[0048] Specifically, a socket for installing an elastic resistance member is provided on the angle adjustment block. The socket is a through hole. The elastic resistance member is arranged in the socket so that it is built into the angle adjustment block. At the same time, the socket penetrates to the core shaft hole so that the end of the elastic resistance member can extend out of the core shaft hole, thereby facilitating the supporting effect of the elastic resistance member.

[0049] The end of the telescopic tongue 50 has two inclined surfaces 504 arranged opposite to each other, and the distance between the ends of the two inclined surfaces 504 is reduced to form a tip, and the vertices on both sides of the tip and the end of the tip are blunt surfaces in the shape of circular arcs. The blunt surface facilitates the telescopic tongue to slide back and forth on the concave arc surface 101 and the teeth, so that the contact surface between the tip of the telescopic tongue and the above surface is an arc surface contact, thereby achieving a smoother movement of the telescopic tongue without getting stuck.

[0050] Specifically, the telescopic tongue 50 includes a columnar base 505, a contact 506 arranged at one end of the columnar base 505, and an elastic member 501 arranged at the other end of the columnar base 505. One end of the elastic member 501 abuts against the columnar base 505. The elastic member 501 is a spring, and the other end is limited by a plug-in that is also arranged in the mounting hole. The plug-in can be a machine screw. A limiting groove 503 is provided on the columnar base 505. The limiting groove 503 can be a long groove. A through hole that is perpendicular to the long groove is provided on the angle adjustment block. A limiting column 502 is provided in the through hole. The end of the limiting column 502 is inserted into the long groove. The end of the contact 506 of the telescopic tongue 50 has two inclined surfaces 504 that are arranged opposite to each other. The distance between the ends of the two inclined surfaces 504 is reduced to form a tip. This can limit the jumping range of the telescopic tongue 50 and play a role in limiting, thereby preventing the tooth groove between the telescopic tongue 50 and the tooth 509 from being too tightly inserted, resulting in the shaft being unable to rotate or rotating unsmoothly.

[0051] A circle of teeth 509 is also provided on the core shaft. The teeth 509 are arranged close to the docking portion 10 , and the telescopic tongue 50 is plugged in with the teeth 509 .

[0052] Specifically, the plurality of teeth 509 are arranged continuously and adjacently along the circumference of the first core axis.

[0053] The outer surface of the docking portion 10 has a plurality of continuously connected concave arc surfaces 101 surrounding the circumference thereof. The main function of the concave arc surface 101 is to facilitate the sliding back and forth of the telescopic tongue structure without getting stuck. The inner surface of the matching portion 20 is a plurality of continuously connected convex arc surfaces arranged around the circumference thereof, mainly to facilitate the clamping between the docking portion 10 and the matching portion 20. The concave arc surface 101 and the convex arc surface can be completely matched. Preferably, there is a gap between the concave arc surface 101 and the convex arc surface, so that the convex arc surface of the telescopic tongue 50 can extend out to abut against the concave arc surface 101.

[0054] The bottom surface of the concave arc surface 101 of the docking portion 10 is connected to the outer surface of the core shaft provided with the teeth, so as to facilitate the sliding back and forth of the telescopic tongue structure, and the telescopic tongue 50 will not be stuck at the connection position between the concave arc surface 101 and the teeth.

[0055] At least two joint planes are arranged on the outer periphery of the angle adjustment block, and at least one of the joint planes is inclined relative to the core shaft along the axial direction of the core shaft, and grooves are arranged between adjacent joint planes.

[0056] At least two tooth-shaped protrusions are arranged on the outer periphery of the angle adjustment block, and a splicing plane is arranged on the tooth-shaped protrusions.

[0057] Along the rotation direction of the angle adjustment block, each tooth-shaped protrusion is connected to the groove, and the tooth-shaped protrusion and the groove connected thereto form a matching use group.

[0058] The inclination direction of the joint plane and the groove on the tooth-shaped protrusion of the matching use group is the same.

[0059] Embodiments of the present invention,

[0060] Reference Figure 3 , shows a three-dimensional schematic diagram of an embodiment of the core shaft of the present invention. As shown in the figure, the core shaft 110 includes a docking portion 10 with a polygonal cross section, and preferably also includes a first connecting end 112 and a second connecting end 113 arranged on both sides of the docking portion 10, wherein the first connecting end 112 and the second connecting end 113 are used for fixed connection with an external structure, and the docking portion 10 is used to cooperate with the angle adjustment block 120 to complete angle adjustment and locking and fixing after adjustment.

[0061] The polygons referred to herein include, but are not limited to, triangles, quadrilaterals, pentagons, hexagons, etc., and preferably regular polygons are used. Specifically, in this embodiment, the cross section of the docking portion 10 is a regular hexagon. In addition, the polygons referred to herein also include approximate polygons, such as Figure 3 As shown in , each side surface of the docking portion 10 is recessed toward the axial direction of the core shaft.

In order to achieve fixed connection between the first connection end 112, the second connection end 113 and the external structure, radial threaded holes 116 are provided on the outer surfaces of the first connection end 112, the second connection end 113. When the first connection end 112 and the second connection end 113 are respectively mounted on the frame 200, threaded connectors 70 are provided at corresponding positions of the frame 200 and inserted into the threaded holes 116, thereby fixing the mandrel 110 on the frame 200.

[0063] In addition, at least one notch 114 is provided on the outer surface of the first connection end 112 near the docking portion 10 along the circumferential direction, and the notch 114 serves as a socket for cooperating with the elastic resistance member. Preferably, a plurality of notches 114 are evenly distributed along the circumference of the first connection end 112. Further, the core shaft 110 is provided with at least two rows of the above-mentioned grooves along the axial direction (only one row is shown in the figure). An avoidance notch 115 is provided on the outer surface of the first connection end 112 away from the docking portion 10.

[0064] Reference Figure 4 , shows a three-dimensional schematic diagram of an embodiment of the angle adjustment block of the present invention. As shown in the figure, the angle adjustment block 120 is provided with a core shaft hole penetrating the angle adjustment block along the thickness direction, and the core shaft hole is divided into a first hole 121 and a second hole 122 that are interconnected along the axial direction, wherein the cross section of the first hole 121 corresponding to the first connecting end 112 is circular, and the cross section of the second hole 122 corresponding to the second connecting end 113 is hexagonal.

[0065] The inner surface of the first hole 121 is provided with a mounting hole 123, in which an elastic resistance member 60 is installed. The elastic resistance member is preferably a ball plunger, and the end of the ball plunger can be retracted into the mounting hole when subjected to a certain external force, and extend from the mounting hole after the external force is released.

[0066] Back to Figure 1 A plurality of slots 124 are provided on the side of the angle adjustment block 120. As a preferred embodiment of the slots 124, a plurality of protrusions 125 are provided on the side of the angle adjustment block 120 along the axial direction of the core shaft hole. The plurality of protrusions 125 are evenly distributed around the core shaft hole, and slots 124 are formed between adjacent protrusions 125. The limiting portion 30 is the protrusion 125.

[0067] As another preferred embodiment of the slot 124, it can also be a groove set on the side of the angle adjustment block 120 and recessed into the angle adjustment block 120. In this case, the setting position on the frame 200 is a protruding portion set with a recess, and the two are locked together, which can further lock the rotation of the angle adjustment block on the core shaft.

[0068] At least two joint planes are provided on the outer circumference of the angle adjustment block 120, at least one of the joint planes is inclined relative to the core shaft hole along the axial direction of the core shaft hole, and a positioning hole is provided on the joint plane. A groove is also provided between adjacent joint planes. Specifically, a plurality of inclined tooth-shaped protrusions are provided on the outer circumference of the angle adjustment block 120, and the tooth-shaped protrusions are inclined in a clockwise direction or in a counterclockwise direction around the axis of the core shaft, and each tooth-shaped protrusion is used in conjunction with a groove provided along the rotation direction of the angle adjustment block and close to it.

[0069] Specifically, in this embodiment, the circumference of the angle adjustment block is provided with a first stitching plane 126a, a second stitching plane 126b, a third stitching plane 126c, a fourth stitching plane 126d, a fifth stitching plane 126e and a sixth stitching plane 126f in sequence, wherein the first stitching plane 126a is parallel to the axial direction of the core shaft 110, and the second stitching plane 126b, the third stitching plane 126c, the fourth stitching plane 126d, the fifth stitching plane 126e and the sixth stitching plane 126f are inclined relative to the core shaft 110, and the inclination angles are different.

[0070] The inclination angles referred to herein are different, that is, they include different angle values ​​and different inclination directions. The inclination directions of the second splicing plane 126b and the third splicing plane 126c in the figure are defined as negative, and the fourth splicing plane 126d, the fifth splicing plane 126e and the sixth splicing plane 126f are positive. According to the above definition, the inclination angles of the first splicing plane 126a to the sixth splicing plane 126f in this embodiment are 0°, -10°, -5°, +5°, +15° and +10° respectively, and angle marks are set on the angle adjustment block corresponding to each splicing plane. According to the different number of angle adjustment gears, the number of splicing planes and the inclination angle can be freely adjusted.

[0071] When it is necessary to adjust inward, the gear position for the inner arc surface is adjusted to +5°, +10°, and +15° scale marks; when it is necessary to adjust outward, the gear position for the outer arc surface is adjusted to -5° and -10° scale marks; when it is necessary to adjust to the same plane, the gear position is the 0° scale mark.

[0072] Preferably, grooves are provided between adjacent joint planes, and the grooves cooperate with the hooks in the locking device. Along the rotation direction of the angle adjustment block, each toothed protrusion is connected to the groove, and the toothed protrusion and the groove it is connected to form a matching group, and the joint planes and grooves on the toothed protrusions of the matching group have the same inclination direction. Specifically, the groove used in conjunction with the first joint plane 126a is the first groove 127a, the groove used in conjunction with the second joint plane 126b is the second groove 127b, the groove used in conjunction with the third joint plane 126c is the third groove 127c, the groove used in conjunction with the fourth joint plane 126d is the fourth groove 127d, the groove used in conjunction with the fifth joint plane 126e is the fifth groove 127e, and the groove used in conjunction with the sixth joint plane 126f is the sixth groove 127f.

[0073] In addition, as shown in the figure, since the areas of the third joint plane 126c and the fourth joint plane 126d are relatively small, in order to increase the contact area between the joint plane and the joint block 340, the angle adjustment block is further provided with a first extension surface 128 flush with the third joint plane 126c and a second extension surface 129 flush with the fourth joint plane 126d, so as to increase the areas of the third joint plane 126c and the fourth joint plane 126d respectively. Specifically, the setting rule of the extension surface is: the extension surface and the matching joint plane are arranged on both sides of the matching groove, and the extension surface is parallel to the joint plane and has the same height.

[0074] Reference Figure 1 , Figure 5 , Figure 5 A three-dimensional schematic diagram of an embodiment of a locking device of the present invention is shown. As shown in the figure, the locking device 300 includes a base 310, a handle 320, a sub-handle 330, a splicing block 340 and a hook 350. The splicing block 340 is fixedly connected to the base 310, the handle 320 is rotatably connected to the base 310 via a rotating shaft 321, the sub-handle 330 is rotatably connected to the handle 320 via a rotating shaft 331, and the hook 350 is rotatably connected to the handle 320 via a rotating shaft 351. When the handle 320 is rotated upward, the end of the hook 350 away from the rotating shaft 351 tilts upward, and the hook 350 enters an unlocked state; when the handle 320 is rotated downward, the end of the hook 350 away from the rotating shaft 351 swings downward, and the hook 350 enters a locked state.

[0075] In addition, a positioning column 311 is provided on the base 310, and a bayonet is provided on the auxiliary handle 330. When the auxiliary handle 330 is rotated downward via the rotating shaft 331 so that the positioning column 311 is buckled into the bayonet, the upward rotation of the handle 320 is restricted, and the hook 350 is fixed in a locked state. At this time, the handle 320 can be supported and limited by the cross bar 332 on the auxiliary handle 330.

[0076] In this embodiment, the splicing block 340 is preferably a rectangular block, and the plane spliced ​​with the angle adjustment block has no tilt angle. During processing, it is only necessary to ensure the accuracy of the splicing plane on the angle adjustment block. Compared with the solution of making the splicing block 340 have a tilt angle, the form of making the splicing plane of the angle adjustment block have a tilt angle while the splicing block does not have a tilt angle can reduce the processing difficulty, help improve the installation accuracy, and ensure that the locking after splicing is more reliable and tight.

[0077] The hook 350 is in a U shape, including connecting parts located on both sides of the handle 320 and rotatably connected to the handle 320, and a middle part connecting the connecting parts on both sides. When the hook 350 is buckled with the angle adjustment block, the middle part is stuck in the groove of the angle adjustment block 120, and the connecting parts on both sides are located on the outside of the angle adjustment block 120. The joint plane of the angle adjustment block 120 and the matching surface of the joint block 340 are directly joined together during assembly, and then the hook 350 is hung in the outer groove of the angle adjustment block. There can be a sufficiently large contact surface between the joint plane of the angle adjustment block 120 and the matching surface of the joint block 340 during assembly, so that the positioning between the two is more accurate and the alignment is more convenient during assembly. The hook 350 is a U-shaped hook, which encloses all the joint parts of the angle adjustment block and the joint block in the hook 350, and can be locked when locked. It plays a pulling role, and tightens the angle adjustment block and the splicing block together, and also realizes a larger locking range. Since the hook is U-shaped, it will enclose a certain space range, and the angle adjustment block is provided with a toothed protrusion and a groove. When the hook is hung in the groove of the toothed protrusion, the hook will enclose a whole toothed protrusion on the angle adjustment block, and the toothed protrusion plays a load-bearing role, so that there is a larger contact surface and pulling fulcrum for buckle locking between the hook and the angle adjustment block, so that the locking is tighter. One end of the groove of the angle adjustment block 120 is completely open, and when the hook 350 needs to be stuck in the groove, it can be put in very smoothly, without the need for special alignment, and is more convenient to operate.

[0078] Reference Figure 6 The mating surface of the splicing block 340 is preferably also provided with an avoidance groove 341 and a positioning column 342, wherein the avoidance groove is used to accommodate the portion of the angle adjustment block that is not involved in the assembly to avoid interference. The positioning column 342 cooperates with the positioning hole 1210 on the splicing plane to achieve the positioning connection between the splicing block and the splicing plane on the angle adjustment block 120, plays the role of alignment and limiting, and can further bear the force from the entire climbing bracket after splicing. Of course, it is also possible to set the positioning hole on the splicing block and set the positioning column on the splicing plane.

[0079] The present invention also discloses a display screen assembly using the above climbing bracket, which includes a display screen 400 and a climbing bracket, and the display screen is mounted on the climbing bracket. Figure 7 , showing a partial schematic diagram of two climbing brackets connected to each other according to the present invention. As shown in the figure, each climbing bracket includes a frame 200, a locking device 300 and the above-mentioned multi-angle adjustment assembly 100, and the locking device 300 and the multi-angle adjustment assembly 100 are respectively fixed on opposite sides of the frame 200. The figure shows the specific way in which the multi-angle adjustment assembly 100 on one climbing bracket cooperates with the locking device 300 on the locking device 300 on another climbing bracket.

[0080] The connection method of the multi-angle adjustment component 100 and the frame 200 is as follows: the first connection end 112 and the second connection end 113 of the core shaft 110 are fixedly connected to the frame 200 by screws respectively. The core shaft 110 is inserted into the core shaft hole, specifically, the first connection end 112 is inserted into the first hole 121, and the docking part 10 is inserted into the second hole 122. When the docking part 10 and the second hole 122 are plugged and adapted, the circumferential curved surfaces of the two fit each other, the angle adjustment block 120 cannot rotate relative to the core shaft 110, and the angle adjustment block 120 is in a locked state; when the angle adjustment block 120 slides along the core shaft 110 until the docking part 10 is separated from the second hole 122 and enters the first hole 121, since the diameter of the docking part 10 is smaller than the aperture of the first hole 121, the angle adjustment block 120 can rotate relative to the core shaft 110.

[0081] The frame 200 is provided with a clamping strip 201 corresponding to the clamping slot 124. When the docking portion 10 is inserted into the second hole 122, the clamping strip 201 is clamped into the clamping slot 124 to further lock the angle adjustment block 120. When the docking portion 10 is separated from the second hole 122, the clamping strip 201 is also separated from the clamping slot 124. If the clamping slot 124 is formed by being recessed between the protrusions toward the angle adjustment block, the clamping strip 201 is correspondingly replaced by an inserting strip that can be inserted into the clamping slot.

[0082] In the above process, the ball plunger cooperates with the notch to achieve the functions of fastening and positioning. When the angle adjustment block 120 is rotated into place and the docking portion 10 is adapted and plugged into the second hole 122, the ball plunger is plugged into a circle of notches 114 distributed along the circumferential direction. When the angle adjustment block 120 slides, the ball plunger is respectively plugged into the notches 114 at different positions in the axial direction, so that the angle adjustment block 120 stays in the locked position where the docking portion 10 is adapted and plugged into the second hole 122, or stays in the unlocked position where the docking portion 10 enters the first hole 121.

[0083] In summary, the climbing bracket is used as follows: the locking device 300 on one climbing bracket is used in conjunction with the multi-angle adjustment component 100 on the other climbing bracket, the joint block 340 on the locking device 300 is fitted with a joint plane on the multi-angle adjustment component 100, and the hook 350 is buckled into the groove corresponding to the joint plane, so that the two climbing brackets can be quickly connected. When the joint block 340 is fitted with the first positioning surface 141, the two climbing brackets are parallel to each other, and when the joint block 340 is fitted with any one of the second positioning surface 142 to the sixth positioning surface 146, the two climbing brackets have an angle equal to the inclination angle of the joint plane, such as Figure 8 As shown, when the splicing block 340 is attached to the +10° splicing plane, the side of the display screen assembly provided with the display screen forms a continuous inwardly concave arc shape, that is, an inner arc splicing mode; Fig. 9 As shown, when the splicing block 340 is in contact with the splicing plane of -10°, the side of the display screen assembly on which the display screen is provided forms a continuous arc shape convex outward, that is, an outer arc splicing method, and the positive and negative indications of the splicing angles are: when the inner arc is spliced, the angle is positive, and when the outer arc is spliced, the angle is negative.

[0084] When the angle adjustment is required, release the hook 350, slide the angle adjustment block 120 so that the card strip 201 is disengaged from the card slot 124, and the docking part 10 enters the first hole 121, then the angle adjustment block 120 can be rotated to adjust the angle, when the adjustment is in place, slide the angle adjustment block 120 in the opposite direction, so that the docking part 10 is plugged into the second hole 122 again, and the card strip 201 is inserted into the card slot 124 again, then the angle adjustment block 120 can be locked.

[0085] The display screen and the climbing bracket in this embodiment are detachably connected. When the display screen assembly is used outdoors, the display screen itself is relatively light and thin and not resistant to wind resistance, so it needs to be fixed by a climbing bracket. At the same time, the climbing bracket can also support the maintenance personnel to climb. When the display screen assembly is used indoors, since there is no need to consider the problem of wind resistance, the climbing bracket can be omitted. That is, the angle adjustment block and the locking device 300 provided on the climbing bracket can lock the climbing bracket and can also lock the display screens. The multi-angle adjustment device of the present application has stronger adaptability, can be used for lighter display screens as well as heavier climbing brackets, and has a better load-bearing effect.

[0086] The above is a specific description of the preferred implementation of the present invention, but the invention is not limited to the embodiments. Those skilled in the art may make various equivalent modifications or substitutions without violating the spirit of the present invention. These equivalent modifications or substitutions are all included in the scope defined by the claims of this application.
