The elastic resistance member is respectively plugged into and matched with the sockets at different positions in the axial direction, so that the sliding member stays in a locked position where the locking column and the locking hole are plugged into each other, or stays in an unlocked position where the locking column and the locking hole are separated.

[0053] The sockets are arranged in at least two rows along the axial direction of the rotating shaft, and the number of sockets in each row along the circumferential direction of the rotating shaft is at least one, so that it is convenient to limit at different positions when sliding to unlock or lock, and prevent the sliding member from sliding randomly on the rotating shaft.

[0054] The second fixing seat is provided with an elastic resistance piece arranged along the axial direction of the rotating shaft, and the end surface of the angle adjustment block close to the second fixing seat is provided with a socket.

[0058] The socket is a plurality of continuous tooth grooves arranged on the rotating shaft and around the axial direction thereof. The elastic resistance member is a telescopic tongue structure, which includes a telescopic tongue, an elastic member for supporting the telescopic tongue, and a limit column arranged perpendicular to the moving direction of the telescopic tongue. The telescopic tongue is provided with a limit groove, and the limit column is inserted in the limit groove to limit the range of the telescopic tongue's jumping. The end of the telescopic tongue abuts against the tooth groove. Thus, the angle adjustment block has a certain resistance when rotating, and is not easy to rotate randomly, and provides a hand feeling when rotating.

[0059] 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.

[0060] 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 it is connected to form a matching set, and the splicing plane on the tooth-shaped protrusion of the matching set and the groove have the same inclination direction.

[0064] Embodiments of the present invention:

[0065] The first fixing seat 110 is preferably a circular ring, which is fixedly connected to the external component by screws or other threaded fasteners. The second fixing seat 120 has a step hole 121 coaxial with the first fixing seat 110, and a coaxial shaft hole 122 is provided at the center of the step hole 121. The second fixing seat 120 is also provided with a mounting hole (not shown), which is arranged along the radial direction of the shaft hole 122 and is connected to the shaft hole 122.

[0066] The two ends of the rotating shaft 130 are rotatably connected to the first fixing seat 110 and the second fixing seat 120 respectively. Specifically, the rotating shaft 130 includes a head end connected to the first fixing seat 110 and a tail end connected to the second fixing seat 120, wherein the rotating shaft 130 is provided with at least one groove along the circumferential direction, and at the same time, the rotating shaft 130 is provided with at least two rows of the above grooves along the axial direction, wherein the grooves include a first groove 131 arranged near the tail end, and a second groove 132 arranged near the head end, preferably, a plurality of first grooves 131 and a plurality of second grooves 132 are evenly distributed along the circumference of the head end. The tail end of the rotating shaft 130 is provided with an annular groove, and a plurality of tooth grooves are provided at the bottom of the annular groove, and protruding teeth 133 are provided between the tooth grooves. A straight clamping surface 135 is provided on the outer surface of the rotating shaft 130, and the clamping surface 135 is parallel to the axis of the rotating shaft 130.

[0067] A through hole is provided at the center of the angle adjustment block 140, and a stop surface 1411 is provided in the through hole. The stop surface is parallel to the axis of the rotating shaft 130. The stop surface 1411 of the angle adjustment block 140 and the clamping surface 135 of the rotating shaft 130 are matched and clamped so that the two cannot rotate relative to each other. When the angle adjustment block 140 rotates, the rotating shaft 130 rotates at the same time, that is, the angle adjustment block 140 can rotate relative to the first fixed seat 110 and the second fixed seat 120 respectively through the rotating shaft 130. Of course, the two ends of the rotating shaft 130 can also be fixedly connected to the first fixed seat 110 and the second fixed seat 120.

[0068] The side of the angle adjustment block 140 installed with the second fixing seat 120 has a boss 1412, and the boss 1412 is installed in cooperation with the step hole 121 of the second fixing seat 120 to provide support and guidance for the angle adjustment block 140 on the second fixing seat 120 when rotating. A ball head plunger 124 with the ball head facing the boss 1412 is also installed on the second fixing seat 120, and a concave hole that cooperates with the ball head is provided on the boss 1412. When the angle adjustment block 140 rotates, the ball head plunger 124 slides through the concave hole to provide rotation resistance for the angle adjustment block 140. When the angle adjustment block 140 rotates to a predetermined position, the ball head is located in the concave hole.

[0069] The locking device is used to lock and fix the angle adjustment block 140 after it rotates to the set position. As a preferred embodiment of the locking device, it includes a sliding member 150 arranged between the first fixing seat 110 and the angle adjustment block 140. The sliding member 150 is preferably a ring sleeved on the rotating shaft 130. The first fixing seat 110 is provided with a plurality of guide posts 134 extending along the axial direction of the rotating shaft 130. The sliding member 150 is provided with guide holes, and the guide posts 134 are inserted into the guide holes. In this way, the sliding member 150 can slide along the axial direction of the rotating shaft 130 without rotating. Of course, the guide posts can also be provided on the sliding member 150, and the guide holes can be provided on the first fixing seat 110.

[0070] A locking column 151 is also provided on the sliding member 150, and a locking hole 147 is provided on the angle adjustment block 140. Sliding the sliding member 150 allows the locking column 151 to be inserted into the locking hole. Since the sliding member 150 cannot rotate, the rotation of the angle adjustment block 140 can be limited; sliding the sliding member 150 allows the locking column 151 to disengage from the locking hole, and the angle adjustment block 140 can then rotate freely.

[0071] Preferably, a plurality of ball plungers 152 are radially arranged on the circumference of the sliding member 150, and one end of the ball plunger 152 extending into the central through hole of the sliding member 150 is a ball head, and the ball plunger 152 is threadedly connected to the sliding member 150, so that the length of the ball head extending into the central through hole can be adjusted by rotating the sliding member 150 relative to the sliding member 150. When the sliding member 150 slides to the locking position for locking the angle adjustment block 140, the ball head of the ball plunger 152 is embedded in the first groove 131 at the head end of the rotating shaft 130, and when the sliding member 150 slides to the unlocking position separated from the angle adjustment block 140, the ball head of the ball plunger 152 is embedded in the second groove 132, thereby realizing the positioning of the sliding position of the sliding member 150.

[0072] In addition, the circumference of the sliding member 150 preferably further extends with a plurality of bosses 153, on which the locking posts 151 are distributed. The bosses 153 can be used as a handle for the user to push the sliding member 150, and can also increase the distribution radius of the locking posts 151, thereby enhancing the locking effect with the angle adjustment block 140.

[0073] Preferably, a telescopic tongue 160, a spring 170 and a mounting seat 180 are sequentially provided in the mounting hole on the second fixing seat 120 that is connected to the rotating shaft hole 122, and is connected and fixed in the radial mounting hole that is connected to the rotating shaft hole 122 via the mounting seat 180. The telescopic tongue 160 can elastically move in the hole through the spring, and the tip of the telescopic tongue 160 is inserted and adapted in the tooth groove. Under the action of the spring 170, the tip of the telescopic tongue 160 always applies a suitable rotational resistance to the rotating shaft 130. Through the cooperation between the telescopic tongue 160 and the tooth groove, the resistance of the rotating shaft 130 during rotation can be increased, thereby preventing the rotating shaft 130 from rotating at will.

[0074] Furthermore, a limiting groove is provided on the telescopic tongue 160 along the radial direction of the rotating shaft 130, and a limiting column 123 is correspondingly provided on the second fixed seat 120. The limiting column 123 is inserted into the limiting groove, thereby limiting the range of the telescopic tongue 160 to limit the jumping range, which can play a limiting role and avoid the situation where the telescopic tongue 160 is too tightly inserted into the tooth groove, resulting in the inability or uneven rotation of the rotating shaft.

[0075] Reference Figure 3, shows a front view of an embodiment of the angle adjustment block of the present invention. As shown in the figure, the center of the angle adjustment block is provided with a shaft hole for the shaft 130 to pass through, and at least two joint planes are provided in the circumferential direction, at least one of the joint planes is inclined relative to the shaft along the axial direction of the shaft, and a positioning hole is provided on the joint plane. A groove is also provided between adjacent joint planes. Preferably, the extension direction of each groove is parallel to the inclination direction of the corresponding joint plane. Specifically, a plurality of inclined tooth-like protrusions are provided on the periphery of the angle adjustment block 140, and the tooth-like protrusions are inclined in a clockwise direction or in a counterclockwise direction around the axis of the shaft, and each tooth-like protrusion is used in a matching group with a groove arranged along the rotation direction of the angle adjustment block and close to it. Further, the joint planes and grooves on the tooth-like protrusions of the matching group have the same inclination direction. The joint plane is inclined relative to the axis of the shaft axially, which can be understood as that in three-dimensional space, when the joint plane and the axis of the shaft are infinitely extended, the two will intersect.

[0076] Specifically, in this embodiment, a first joint plane 141, a second joint plane 142, a third joint plane 143, a fourth joint plane 144, a fifth joint plane 145 and a sixth joint plane 146 are sequentially arranged on the circumference of the angle adjustment block, wherein the first joint plane 141 is parallel to the axial direction of the rotating shaft 130, and the second joint plane 142, the third joint plane 143, the fourth joint plane 144, the fifth joint plane 145 and the sixth joint plane 146 are inclined relative to the rotating shaft 130, and the inclination angles are different. The groove used in conjunction with the first joint plane 141 is the first groove 148a, the groove used in conjunction with the second joint plane 142 is the second groove 148b, the groove used in conjunction with the third joint plane 143 is the third groove 148c, the groove used in conjunction with the fourth joint plane 144 is the fourth groove 148d, the groove used in conjunction with the fifth joint plane 145 is the fifth groove 148e, and the groove used in conjunction with the sixth joint plane 146 is the sixth groove 148f.

[0077] 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 142 and the third splicing plane 143 in the figure are defined as negative, and the fourth splicing plane 144, the fifth splicing plane 145 and the sixth splicing plane 146 are positive. According to the above definition, the inclination angles of the first splicing plane 141 to the sixth splicing plane 146 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.

[0078] 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.

[0079] In addition, as shown in the figure, since the areas of the third joint plane 143 and the fourth joint plane 144 are relatively small, in order to increase the contact area between the joint plane and the joint block, an extension surface is also provided on the angle adjustment block, specifically including a first extension surface 149 flush with the third joint plane 143, and a second extension surface 1410 flush with the fourth joint plane 144, so as to increase the areas of the third joint plane 143 and the fourth joint plane 144. 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.

[0080] Reference Figure 4 , shows a three-dimensional schematic diagram of an embodiment of a climbing bracket of the present invention. As shown in the figure, the climbing bracket includes a frame 200, a locking device 300 and the above-mentioned multi-angle adjustment connection assembly 100, and the locking device 300 and the multi-angle adjustment connection assembly 100 are respectively fixed on different sides of the frame 200, and are preferably arranged on opposite sides of the frame 200 in this embodiment.

[0081] Reference Figure 5 , shows a three-dimensional schematic diagram of an embodiment of the locking device of the present invention. 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.

[0082] 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.

[0083] 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.

[0084] 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 140, and the connecting parts on both sides are located on the outside of the angle adjustment block 140. The joint plane of the angle adjustment block 140 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 140 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 piece of 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 140 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.

[0085] 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 cooperates with the positioning hole 1413 on the splicing plane to achieve the positioning connection between the splicing block and the splicing plane on the angle adjustment block 140, plays the role of alignment and limiting, and can further bear the force from the spliced ​​climbing bracket. Of course, the positioning hole can also be set on the splicing block, and the positioning column can be set on the splicing plane.

[0086] The present invention also discloses a display screen assembly using the above climbing bracket, which comprises a display screen and a climbing bracket, wherein the display screen is mounted on the climbing bracket. Figure 7 , Figure 8 , respectively showing a three-dimensional schematic diagram and a top view of the connection between the locking device of the present invention and the multi-angle adjustment connection assembly. As shown in the figure, the locking device 300 on one climbing bracket is used in conjunction with the multi-angle adjustment connection assembly 100 on the other climbing bracket, and the splicing block 340 on the locking device 300 is in contact with a splicing plane on the multi-angle adjustment connection assembly 100, and the hook 350 is snapped into the groove corresponding to the splicing plane, so that a quick connection between the two climbing brackets can be achieved. When the splicing block 340 is in contact with the first splicing plane 141, the two climbing brackets are parallel to each other. When the splicing block 340 is in contact with any one of the second splicing plane 142 to the sixth splicing plane 146, the two climbing brackets have an angle that is the same as the inclination angle of the splicing plane, such as Fig. 9 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.10 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.

[0087] 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.

[0088] 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 can 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.
