Description

Technical Field

[0001] This utility model belongs to the technical field of office supplies or furniture, and in particular relates to a bracket. Background Technology

[0002] Currently, monitors, speakers, and other devices are often fixed to desktops or walls using dedicated stands, or mounted on floor stands. These stands can all be equipped with movable connecting arms, on which the devices are then mounted. In daily use, users simply need to move the connecting arms to easily adjust the position and angle of the devices, flexibly adapting to different scenarios such as office work and entertainment, and fully meeting diverse usage needs.

[0003] In existing technologies, the connection between the main structure and the connecting arm of this type of bracket generally relies on screws for fixation. However, this method poses a significant safety hazard when adjusting the position of the connecting arm relative to the main structure: the screws must be loosened before adjustment, which causes a sudden and significant decrease in the connection strength between the main structure and the connecting arm, making it highly susceptible to the risk of the connecting arm and the equipment falling accidentally.

[0004] Therefore, there is an urgent need for a scaffold to solve the above problems. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a bracket that improves the flexibility of the position adjustment of the connecting structure on the column, and the connecting structure will not fall off the column.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] A support frame is provided, including a column and a connecting structure movably disposed on the column. The support frame further includes a fall protection structure, which includes:

[0008] The first limiting member is movably disposed on the column and located below the connecting structure, and the position of the connecting structure above the first limiting member along the height direction of the column is adjustable. The first limiting member has a first locking state and a first unlocking state. In the first unlocking state, the position of the first limiting member along the height direction of the column is adjustable. In the first locking state, the first limiting member is limited to the column.

[0009] The second limiting member is movably disposed on the column or the connecting structure. The second limiting member has a second locking state and a second unlocking state. In the second locking state, the second limiting member is used to constrain the movement of the connecting structure on the column. In the second unlocking state, the connecting structure can move relative to the column.

[0010] Optionally, the first limiting member is rotatably and / or movably disposed on the column, driving the first limiting member to rotate and / or move, and the first limiting member switches between a first locked state and a first unlocked state.

[0011] The second limiting member is rotatably and / or movablely disposed on the column or connecting structure, driving the second limiting member to rotate and / or move, and the second limiting member switches between a second locked state and a second unlocked state.

[0012] The switching action of the first limit member may be the same as or different from that of the second limit member.

[0013] Optionally, the first limiting member is rotatably disposed on the column about the first rotation center line, driving the first limiting member to rotate about the first rotation center line, and the first limiting member switches between the first locked state and the first unlocked state.

[0014] The second limiting member is rotatably disposed on the column or connecting structure around the second rotation center line, driving the second limiting member to rotate around the second rotation center line, and the second limiting member switches between the second locked state and the second unlocked state.

[0015] The first rotation center line is parallel to the height direction of the column. The second rotation center line is parallel to the first rotation center line or is set at an angle to it. When the second rotation center line is parallel to the first rotation center line, the second rotation center line and the first rotation center line are staggered.

[0016] When the first limiting member switches between the first locked state and the first unlocked state, the first limiting member rotates by a first preset angle. When the second limiting member switches between the second locked state and the second unlocked state, the second limiting member rotates by a second preset angle. The first preset angle is greater than the second preset angle.

[0017] Optionally, the first limiting member includes a first limiting sleeve and a second limiting sleeve that can be detachably connected. The first limiting sleeve is movably sleeved on the column. In the first locked state, the second limiting sleeve is at least partially sleeved on the first limiting sleeve and limits the first limiting sleeve to the column. In the first unlocked state, the second limiting sleeve is separated from or released from the first limiting sleeve. The position of the first limiting sleeve along the height direction of the column is adjustable.

[0018] When the first limiting member is driven to move along the first direction, the first limiting member switches from the first unlocked state to the first locked state. When the first limiting member is driven to move along the second direction, the first limiting member switches from the first locked state to the first unlocked state. The second direction is opposite to the first direction.

[0019] Optionally, the locking end of the first limiting sleeve is provided with multiple elastic locking pieces, which are arranged at intervals along the circumference of the first limiting sleeve. A deformation groove is formed between any two adjacent elastic locking pieces, and the deformation groove extends along the locking direction and is opened towards the locking end.

[0020] When the first limiting member switches from the first unlocked state to the first locked state, the second limiting sleeve compresses the elastic locking piece and deforms it along the radial direction of the column towards the column axis. When the first limiting member switches from the first locked state to the first unlocked state, the elastic locking piece returns to its original deformation.

[0021] Optionally, the locking end of the first limiting sleeve is provided with an outer guide slope. When the first limiting member switches from the first unlocked state to the first locked state, the outer guide slope is used to guide the second limiting sleeve to deform the elastic locking piece when the second limiting sleeve moves towards the first limiting sleeve along the column height direction; and / or, the second limiting sleeve is provided with an inner guide slope. When the first limiting member switches from the first unlocked state to the first locked state, the inner guide slope is used to guide the second limiting sleeve to deform the elastic locking piece when the second limiting sleeve moves towards the first limiting sleeve along the column height direction.

[0022] The first limiting sleeve includes a first connecting ring with external threads, and the second limiting sleeve includes a second connecting ring with internal threads. In the first locking state, the second connecting ring is sleeved on the outside of the first connecting ring and threadedly connected to the first connecting ring. When the second limiting sleeve is rotated in the first direction or the second direction, the first limiting member switches between the first locking state and the first unlocking state.

[0023] Optionally, the second limiting member can be movably mounted on the connecting structure;

[0024] The second limiting member is provided with a connecting position. The second limiting member includes a pressing part and a yielding part. When the second limiting member is driven to move, both the pressing part and the yielding part can move to the connecting position. When one of the pressing part and the yielding part moves to the connecting position, the other of the pressing part and the yielding part disengages from the connecting position.

[0025] In the second locking state, the abutment moves to the connection position and locks to the column; in the second unlocking state, the clearance part moves to the connection position and the abutment part releases its lock on the column.

[0026] Optionally, the second limiting member is rotatably disposed in the connecting structure, and the second limiting member is driven to rotate so that both the pressing part and the abutting part can move to the connecting position, so that the second limiting member can switch between the second locked state and the second unlocked state.

[0027] The second limiting member also includes a main body and several operating parts disposed on the main body. Both the pressing part and the avoidance part are disposed on the main body. The operating parts protrude relative to the main body and are located on the side of the main body away from the pressing part.

[0028] Optionally, the connecting structure is provided with an assembly hole, and the connecting structure is sleeved on the column through the assembly hole. The connecting position is located between the hole wall of the assembly hole and the column. In the first locking state, the pressing part is pressed against the column, and the second limiting member is used to constrain the rotation and movement of the connecting structure on the column.

[0029] A soft rubber layer is provided on the abutting part. In the first locking state, the abutting part abuts against the column through the soft rubber layer; or, the bracket also includes a bushing located in the assembly hole. The bushing is sleeved on the column and has a deformable part. In the first locking state, the abutting part abuts against the column through the deformable part.

[0030] The assembly hole has a mounting hole on its wall, and the second limiting member is movably positioned inside the mounting hole.

[0031] Optionally, the connecting structure is provided with a third limiting member. In the second locking state, the second limiting member abuts against the third limiting member to limit the second limiting member to the second locking state.

[0032] Optionally, the bracket may also include a mounting component, and the connection structure includes a connecting arm. The mounting component is fixedly or movably mounted on the connecting arm for supporting the display device and / or audio device.

[0033] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0034] This invention provides a bracket with a first limiting member located below the connecting structure. Whether in the first unlocked or first locked state, the connecting structure can only move above the first limiting member on the column. Therefore, even if the connection strength between the connecting structure and the column decreases, the connecting structure cannot fall off the column due to the limitation of the first limiting member, achieving the purpose of preventing fall. In the first unlocked state, by adjusting the height of the first limiting member on the column, the range of movement of the connecting structure along the vertical direction can be adjusted, improving the flexibility of the connecting structure's position adjustment. In the second locked state, the second limiting member further restricts the movement of the connecting structure on the column, achieving multiple constraints on the position of the connecting structure, improving the stability of the connecting structure installed on the column, and enhancing the fall prevention effect. Furthermore, the first and second limiting members do not interfere with each other in constraining the connecting structure. Even if the first limiting member switches to the first unlocked state due to accidental contact, the second limiting member will still be in the second locked state, and the connecting structure will not fall off. Alternatively, if the second limiting member switches to the second unlocked state due to accidental contact, the first limiting member will still be in the first locked state, and the connecting structure will not fall off. This significantly improves the stability and safety of the connecting structure when installed on the column, and achieves the effect of preventing falls. Attached Figure Description

[0051] It should be understood that in the description of this utility model, the terms "center", "longitudinal", "lateral", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0052] It should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "set," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0053] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0054] like Figures 1 to 8 As shown, this embodiment provides a bracket that improves the flexibility of adjusting the position of the connecting structure 200 on the column 300, and the connecting structure 200 will not fall off the column 300.

[0055] See Figure 1 and Figure 2 The support includes a column 300 and a connecting structure 200 movably disposed on the column 300, and also includes a fall protection structure 100. The fall protection structure 100 includes a first limiting member 110 and a second limiting member 120. The first limiting member 110 is movably disposed on the column 300 and located below the connecting structure 200, and the connecting structure 200 is located above the first limiting member 110 along the height direction of the column 300. Figure 1 The position of the first limiting member 110 (in the Z direction) is adjustable. The first limiting member 110 has a first locking state and a first unlocking state. In the first unlocking state, the position of the first limiting member 110 along the height direction of the column 300 is adjustable. In the first locking state, the first limiting member 110 is limited to the column 300. The second limiting member 120 is movably disposed on the column 300 or the connecting structure 200. The second limiting member 120 has a second locking state and a second unlocking state. In the second locking state, the second limiting member 120 is used to constrain the movement of the connecting structure 200 on the column 300. In the second unlocking state, the connecting structure 200 can move relative to the column 300.

[0056] In the bracket provided in this embodiment, the first limiting member 110 is located below the connecting structure 200. Whether in the first unlocked state or the first locked state, the connecting structure 200 can only move above the first limiting member 110 on the column 300. Therefore, even if the connection strength between the connecting structure 200 and the column 300 decreases, the connecting structure 200 cannot fall off the column 300 due to the limitation of the first limiting member 110, achieving the purpose of preventing fall. In the first unlocked state, by adjusting the height of the first limiting member 110 on the column 300, the range of motion of the connecting structure 200 along the height direction on the column 300 can be adjusted, improving the flexibility of the position adjustment of the connecting structure 200. In the second locked state, the second limiting member 120 can further constrain the movement of the connecting structure 200 on the column 300, achieving multiple constraints on the position of the connecting structure 200, improving the stability of the connecting structure 200 installed on the column 300, and enhancing the fall prevention effect. Furthermore, the first limiting member 110 and the second limiting member 120 do not interfere with each other in constraining the connecting structure 200. Even if the first limiting member 110 switches to the first unlocked state due to accidental contact, the second limiting member 120 can still be in the second locked state, and the connecting structure 200 will not fall off. Alternatively, if the second limiting member 120 switches to the second unlocked state due to accidental contact, the first limiting member 110 can still be in the first locked state, and the connecting structure 200 will not fall off. This significantly improves the stability and safety of the connecting structure 200 installed on the column 300, and achieves the effect of preventing it from falling off.

[0057] In some embodiments, the connecting structure 200 can be moved along the height direction of the column 300 to adjust to the target height position. At this time, the height position can be adjusted by unlocking the first limiting member 110 and the second limiting member 120 asynchronously.

[0058] In some embodiments, the connecting structure 200 can also be rotated around the height of the column 300 to adjust to the target angle position. In this case, without adjusting the height, i.e., only adjusting the angle, the first limiting member 110 is not unlocked, but only the second limiting member 120 is unlocked to achieve the angle position adjustment. The user does not need to support the connecting structure 200 with their hands and can directly rotate the connecting structure 200 without accidentally falling. The operation is convenient and quick. When the target angle position is reached, the second limiting member 120 is switched to the second locking state, which simultaneously restricts the height and angle position of the connecting structure 200 relative to the column 300.

[0059] Specifically, during daily use of the bracket, the first limiting member 110 is switched to the first locking state, and the second limiting member 120 is switched to the second locking state, so that the connecting structure 200 cannot move on the column 300.

[0060] Specifically, when the connecting structure 200 needs to be moved upward, the second limiting member 120 is first switched to the second unlocked state, the first limiting member 110 is kept in the first locked state, and the connecting structure 200 is moved; after the connecting structure 200 is moved to the required height, the second limiting member 120 is first switched to the second locked state, and then the first limiting member 110 is switched to the first unlocked state; then, the first limiting member 110 is moved upward until the first limiting member 110 contacts the connecting structure 200; finally, the first limiting member 110 is switched to the first locked state.

[0061] Specifically, when the connecting structure 200 needs to be moved down, the first limiting member 110 is first switched to the first unlocked state and then moved down; after the first limiting member 110 moves to the required height, the first limiting member 110 is first switched to the first locked state, and then the second limiting member 120 is switched to the second unlocked state; then, the connecting structure 200 is moved down until the connecting structure 200 contacts the first limiting member 110; finally, the second limiting member 120 is switched to the second locked state.

[0062] Specifically, when it is necessary to change the angle of the connecting structure 200 on the column 300, first switch the second limiting member 120 to the second unlocked state, and then rotate the connecting structure 200; after the connecting structure 200 has rotated to the position, switch the second limiting member 120 to the second locking state.

[0063] Optionally, see Figure 1 and Figure 2 The first limiting member 110 is rotatably and / or movably disposed on the column 300, driving the first limiting member 110 to rotate and / or move, and the first limiting member 110 switches between a first locked state and a first unlocked state. This configuration allows the first limiting member 110 to switch between the first locked state and the first unlocked state through one of three switching actions: rotation, movement, or a combination of rotation and movement.

[0064] See Figure 1 and Figure 2 The second limiting member 120 is rotatably and / or movably disposed on the column 300 or the connecting structure 200, driving the second limiting member 120 to rotate and / or move, and switching the second limiting member 120 between a second locked state and a second unlocked state. This configuration allows the second limiting member 120 to switch between the second locked state and the second unlocked state through one of three switching actions: rotation, movement, or a combination of rotation and movement.

[0065] In this embodiment, the switching action of the first limiting member 110 is the same as the switching action of the second limiting member 120.

[0066] Specifically, taking the example where both the switching action of the first limiting member 110 and the switching action of the second limiting member 120 are rotations. (See also...) Figure 1 and Figure 2 The first limiting member 110 is rotatably disposed on the column 300 about the first rotation center line, driving the first limiting member 110 to rotate about the first rotation center line, and the first limiting member 110 switches between a first locked state and a first unlocked state; the second limiting member 120 is rotatably disposed on the column 300 or the connecting structure 200 about the second rotation center line, driving the second limiting member 120 to rotate about the second rotation center line, and the second limiting member 120 switches between a second locked state and a second unlocked state.

[0067] The first rotation center line is parallel to the height direction of the column 300. The second rotation center line is parallel to the first rotation center line or at an angle to it. When the second rotation center line is parallel to the first rotation center line, they are staggered. That is, when the second rotation center line is parallel to the first rotation center line, they are two non-coincident straight lines.

[0068] For example, when the second rotation center line is set at an angle to the first rotation center line, refer to Figure 1 In terms of orientation, the first rotation center line extends along the Z direction and is collinear with the axis of column 300; the second rotation center line is along the horizontal direction ( Figure 1 The second limiting member 120 extends along the X or Y direction and forms a 90-degree angle with the first rotation center line. When the second limiting member 120 switches states, it swings up and down, that is, it swings around the axis in the X or Y direction. When the second rotation center line is parallel to the first rotation center line, both the first and second rotation center lines extend along the Z direction. When the second limiting member 120 switches states, it swings left and right, that is, it swings around the axis in the Z direction.

[0069] Furthermore, when the first limiting member 110 switches between the first locked state and the first unlocked state, the first limiting member 110 rotates by a first preset angle. When the second limiting member 120 switches between the second locked state and the second unlocked state, the second limiting member 120 rotates by a second preset angle. The first preset angle is greater than the second preset angle. The first limiting member 110 is located below the connecting structure 200. When operating the connecting structure 200, it is easy to accidentally touch the first limiting member 110. When the value of the first preset angle is relatively large, the aforementioned accidental touching phenomenon can be effectively avoided, improving the safety of the connecting structure 200 during daily use. The value of the second preset angle is relatively small, which can improve the convenience for users when switching the state of the second limiting member 120, improving the user experience.

[0070] Specifically, taking the switching action of the first limiting member 110 and the switching action of the second limiting member 120 both being movement as an example, the first limiting member 110 is movably disposed on the column 300 along the height direction of the column 300, driving the first limiting member 110 to move along the height direction of the column 300, and the first limiting member 110 switches between a first locked state and a first unlocked state; the second limiting member 120 is movably disposed on the column 300 or the connecting structure 200 along the height direction of the column 300, driving the second limiting member 120 to move along the height direction of the column 300, and the second limiting member 120 switches between a second locked state and a second unlocked state.

[0071] Furthermore, when the first limiting member 110 switches between the first locked state and the first unlocked state, the first limiting member 110 moves a first preset distance. When the second limiting member 120 switches between the second locked state and the second unlocked state, the second limiting member 120 moves a second preset distance, and the first preset distance is greater than the second preset distance. This operation can effectively prevent accidental contact, improve the safety of the connection structure 200 during daily use, and enhance the convenience for users when switching the state of the second limiting member 120.

[0072] Specifically, the switching action of the first limiting member 110 and the switching action of the second limiting member 120 can both be a combination of movement and rotation.

[0073] In other embodiments, the switching action of the first limiting member 110 is different from the switching action of the second limiting member 120.

[0074] For example, when the switching action of the first limiting member 110 is rotation, the switching action of the second limiting member 120 is movement or a combination of rotation and movement; when the switching action of the first limiting member 110 is movement, the switching action of the second limiting member 120 is rotation or a combination of rotation and movement; when the switching action of the first limiting member 110 is a combination of rotation and movement, the switching action of the second limiting member 120 is rotation or movement.

[0075] Optionally, see Figure 2 and Figure 3The first limiting member 110 includes a first limiting sleeve 111 and a second limiting sleeve 112 that can be detachably connected. The first limiting sleeve 111 is movably sleeved on the column 300. In the first locked state, the second limiting sleeve 112 is at least partially sleeved on the first limiting sleeve 111 and limits the first limiting sleeve 111 to the column 300. In the first unlocked state, the second limiting sleeve 112 is separated from or released from the first limiting sleeve 111. The position of the first limiting sleeve 111 is adjustable along the height direction of the column 300. In the first locking state, the second limiting sleeve 112 is at least partially fitted onto the first limiting sleeve 111. The second limiting sleeve 112 can press the first limiting sleeve 111 against the column 300, thus limiting the first limiting sleeve 111 on the column 300 and limiting the relative position between the second limiting sleeve 112 and the first limiting sleeve 111. Consequently, the first limiting member 110 can be stably limited on the column 300, effectively restraining the downward movement of the connecting structure 200 and achieving the purpose of preventing fall. Separating or loosening the second limiting sleeve 112 from the first limiting sleeve 111 releases the constraint of the second limiting sleeve 112 on the first limiting sleeve 111, allowing the positions of both the first limiting sleeve 111 and the second limiting sleeve 112 on the column 300 to be adjusted.

[0076] Specifically, when the first limiting member 110 is driven to move in the first direction, it switches from the first unlocked state to the first locked state; when the first limiting member 110 is driven to move in the second direction, it switches from the first locked state to the first unlocked state. The second direction is opposite to the first direction. Only when the first limiting member 110 is driven to rotate in a specific direction can it switch to the first locked or first unlocked state. This helps to prevent accidental unlocking of the first limiting member 110 due to vibration, collision, or unintentional touch, making the first limiting member 110 more reliable in daily use and improving the safety of the bracket.

[0077] For example, when the switching action of the first limiting member 110 is rotation, one of the first direction and the second direction is clockwise, and the other of the first direction and the second direction is counterclockwise. When the switching action of the first limiting member 110 is movement, one of the first direction and the second direction is vertically upward, and the other of the first direction and the second direction is vertically downward. When the switching action of the first limiting member 110 is a combination of movement and rotation, one of the first direction and the second direction is vertically upward plus clockwise rotation, and the other of the first direction and the second direction is vertically downward plus counterclockwise rotation.

[0078] In some embodiments, see Figure 2 and Figure 3The locking end of the first limiting sleeve 111 is provided with multiple elastic locking pieces 1113, which are arranged at intervals along the circumference of the first limiting sleeve 111. A deformation groove 1111 is formed between any two adjacent elastic locking pieces 1113. The deformation groove 1111 extends along the locking direction and opens towards the locking end. When the first limiting member 110 switches from the first unlocked state to the first locked state, the second limiting sleeve 112 compresses the elastic locking pieces 1113 radially towards the axis of the column 300. Figure 2 The elastic locking piece 1113 deforms (in the positive Y direction) and can compress the column 300, thereby limiting the first limiting sleeve 111 on the column 300. When the first limiting member 110 switches from the first locked state to the first unlocked state, the second limiting sleeve 112 gradually separates from or loosens from the first limiting sleeve 111, and the compressive force of the second limiting sleeve 112 on the elastic locking piece 1113 gradually decreases. The elastic locking piece 1113 restores its deformation, releasing the compression on the column 300, allowing the first limiting sleeve 111 to move on the column 300. The deformation groove 1111 provides space for the deformation of the elastic locking piece 1113.

[0079] The locking direction includes a first direction and a second direction, and the locking end is one end of the first limiting sleeve 111 along the locking direction.

[0080] Specifically, see Figure 3 When the second limiting sleeve 112 compresses and deforms the elastic locking piece 1113, the distance between two adjacent elastic locking pieces 1113 will change, and the width of the deformation groove 1111 will gradually decrease until the two adjacent elastic locking pieces 1113 come into contact.

[0081] In this embodiment, the locking end of the first limiting sleeve 111 is provided with an outer guide slope. When the first limiting member 110 switches from the first unlocked state to the first locked state, the outer guide slope is used to guide the second limiting sleeve 112 to deform the elastic locking piece 1113 as the second limiting sleeve 112 moves towards the first limiting sleeve 111 along the height direction of the column 300. As a guide slope, the outer guide slope can not only automatically correct the position between the first limiting sleeve 111 and the second limiting sleeve 112 when the second limiting sleeve 112 is fitted onto the first limiting sleeve 111, improving the efficiency of the connection between the first limiting sleeve 111 and the second limiting sleeve 112, but also allow the elastic locking piece 1113 to be squeezed by the second limiting sleeve 112.

[0082] Specifically, see Figure 3 When the first limiting member 110 switches from the first unlocked state to the first locked state, the second limiting sleeve 112 moves from bottom to top toward the first limiting sleeve 111. The outer guide slope gradually moves away from the center of the first limiting sleeve 111 in the direction from bottom to top.

[0083] For example, the outer guide slope is the outer surface of the elastic locking piece 1113.

[0084] In other embodiments, see Figure 3 and Figure 4 The second limiting sleeve 112 is provided with an inner guide slope 1122. When the first limiting member 110 switches from the first unlocked state to the first locked state, the inner guide slope 1122 is used to guide the second limiting sleeve 112 to deform the elastic locking piece 1113 as the second limiting sleeve 112 moves along the height direction of the column 300 towards the first limiting sleeve 111. The function of the inner guide slope 1122 is the same as that of the outer guide slope, and will not be described again here.

[0085] Specifically, see Figure 4 When the first limiting member 110 switches from the first unlocked state to the first locked state, the second limiting sleeve 112 moves from bottom to top toward the first limiting sleeve 111. The inner guide slope 1122 gradually moves away from the center of the second limiting sleeve 112 in the direction from bottom to top.

[0086] In other embodiments, the locking end of the first limiting sleeve 111 is provided with an outer guide slope, and the second limiting sleeve 112 is provided with an inner guide slope 1122.

[0087] Specifically, the inner guide slope 1122 is parallel to the outer guide slope, and in the first locking state, the inner guide slope 1122 is in contact with the outer guide slope.

[0088] In this embodiment, see Figure 3 and Figure 4 The first limiting sleeve 111 includes a first connecting ring 1112 with external threads, and the second limiting sleeve 112 includes a second connecting ring 1121 with internal threads. In the first locked state, the second connecting ring 1121 is sleeved on the outside of the first connecting ring 1112 and threadedly connected to the first connecting ring 1112. By rotating the second limiting sleeve 112 in a first direction or a second direction, the first limiting member 110 switches between the first locked state and the first unlocked state. That is, in this embodiment, the switching action of the first limiting sleeve 111 is rotation. This configuration not only allows the first limiting sleeve 111 and the second limiting sleeve 112 to connect and separate quickly, improving the convenience of switching the state of the first limiting member 110, but also ensures the stability of the first limiting member 110 in the first locked state, improving the reliability of the connection structure 200 installed on the column 300.

[0089] For example, the first direction and the second direction extend circumferentially along the first connecting ring 1112 and are in opposite directions.

[0090] In other embodiments, the first limiting sleeve 111 includes a first connecting ring 1112, and the second limiting sleeve 112 includes a second connecting ring 1121. A locking block is provided on one of the outer wall of the first connecting ring 1112 and the inner wall of the second connecting ring 1121, and a slot is provided on the other of the outer wall of the first connecting ring 1112 and the inner wall of the second connecting ring 1121. In the first locked state, the second connecting ring 1121 is sleeved on the outside of the first connecting ring 1112, and the locking block is locked in the slot. In the first unlocked state, the locking block is disengaged from the slot. The second limiting sleeve 112 is moved along the first direction or the second direction, and the first limiting member 110 switches between the first locked state and the first unlocked state.

[0091] For example, the first direction and the second direction extend along the height direction of the column 300 and are in opposite directions.

[0092] In other embodiments, the first limiting sleeve 111 includes a first connecting ring 1112, the second limiting sleeve 112 includes a second connecting ring 1121, and the first limiting member 110 further includes a first insert. The first connecting ring 1112 has a first insertion hole, and the second connecting ring 1121 has a second insertion hole. In the first locked state, the second connecting ring 1121 is sleeved on the outside of the first connecting ring 1112, and the first insert is inserted into the first and second insertion holes. The first insert can contact and abut against the column 300, and the friction between the first insert and the column 300 can effectively constrain the movement of the first limiting member 110 on the column 300. In the first unlocked state, the first insert separates from the column and disengages from the first and second insertion holes; the second limiting sleeve 112 moves along the first or second direction, and the first limiting member 110 switches between the first locked state and the first unlocked state.

[0093] Specifically, the column 300 is provided with a toothed groove, and the end of the first connector that contacts the column 300 is provided with teeth. In the first locking state, the teeth are embedded in the toothed groove, which effectively prevents relative sliding between the first connector and the column 300 and improves the stability of the first limiting member 110 in the first locking state.

[0094] For example, the extension direction of the first socket is the same as the extension direction of the second socket. The first direction extends along the extension direction of the first socket toward the center of the first connecting ring 1112, and the second direction extends along the extension direction of the first socket toward the center of the first connecting ring 1112.

[0095] In some embodiments, the first connector is inserted through the first limiting sleeve 111. One end of the first connector is used to abut against the column 300 to achieve locking. The other end of the first connector cooperates with the second limiting sleeve 112. When the second limiting sleeve 112 is operated to move or rotate, it drives the first connector to move and abut against or release the abutment against the column 300.

[0096] Specifically, the connection structure between the first connector limiting and the second limiting sleeve 112 can adopt existing technology in the field, such as a push-type telescopic mechanism or a ratchet-cam type push-type mechanism. That is, when the first connector is pressed, the first connector locks in the first socket and the second socket; when the first connector is pressed again, the first connector can be unlocked and disengaged from the first socket and the second socket.

[0097] In an optional embodiment, see [link to relevant documentation] Figure 5 and Figure 6 The second limiting member 120 is movably installed on the connecting structure 200. The second limiting member 120 is provided with a connecting position. The second limiting member 120 includes a pressing part 121 and a clearance part 122. When the second limiting member 120 is driven to move, both the pressing part 121 and the clearance part 122 can move to the connecting position. When one of the pressing part 121 and the clearance part 122 moves to the connecting position, the other of the pressing part 121 and the clearance part 122 disengages from the connecting position. In the second locking state, the pressing part 121 moves to the connecting position and locks itself to the column 300 to restrict the movement of the connecting structure 200 on the column 300. In the second unlocking state, the clearance part 122 moves to the connecting position, and the pressing part 121 releases its lock on the column 300, so that the connecting structure 200 can move relative to the column 300.

[0098] In this embodiment, see Figure 5 and Figure 6 The second limiting member 120 is rotatably disposed on the connecting structure 200. Driving the second limiting member 120 to rotate allows both the pressing part 121 and the avoidance part 122 to move to the connecting position, so that the second limiting member 120 can switch between the second locked state and the second unlocked state.

[0099] See Figure 5 and Figure 7 The connecting structure 200 is provided with an assembly hole 220. The connecting structure 200 is sleeved on the column 300 through the assembly hole 220. The connection position is located between the hole wall of the assembly hole 220 and the column 300. In the first locking state, the abutting part 121 abuts against the column 300. The second limiting member 120 is used to constrain the rotation and movement of the connecting structure 200 on the column 300.

[0100] Specifically, see Figure 5 and Figure 6The abutting part 121 protrudes towards the column 300 relative to the relief part 122. When the second limiting member 120 is driven to rotate until the abutting part 121 moves to the connection position, the protruding abutting part 121 can abut against the column 300. The interaction force between the abutting part 121 and the column 300 can constrain the relative movement between the second limiting member 120 and the column 300, thereby constraining the relative movement between the connecting structure 200 and the column 300. When the second limiting member 120 is driven to rotate, the abutting part 121 moves away from the connection position, and the relief part 122 gradually moves towards the connection position. The abutting force of the abutting part 121 on the column 300 gradually decreases, thereby allowing the connecting structure 200 to move relative to the column 300.

[0101] For example, see Figure 6 and Figure 7 The second limiting member 120 includes a main body 123 and a rotating shaft 124. The pressing part 121 and the clearance part 122 are both provided on the main body 123. The connecting structure 200 is provided with a connecting hole 230. The rotating shaft 124 passes through the connecting hole 230 and the main body 123 and rotates with the hole wall of the connecting hole 230.

[0102] In other embodiments, the second limiting member 120 is movably installed on the connecting structure 200 along a preset direction. The connecting position is located between the connecting structure 200 and the column 300, and the abutting part 121 protrudes toward the column 300 relative to the avoidance part 122.

[0103] For example, the preset direction is the height direction of the column 300, and the abutting part 121 is located above the clearance part 122. When the second limiting member 120 is moved downward, the abutting part 121 can move to the connection position and abut against the column 300, thereby constraining the relative movement between the connecting structure 200 and the column 300; when the second limiting member 120 is moved upward, the clearance part 122 can move to the connection position.

[0104] In some embodiments, see Figure 6 and Figure 7 The second limiting member 120 also includes a main body 123 and a plurality of operating parts 125 disposed on the main body 123. A pressing part 121 and a clearance part 122 are both disposed on the main body 123. The operating parts 125 protrude relative to the main body 123 and are located on the side of the main body 123 opposite to the pressing part 121. Pressing or pushing the operating parts 125 causes the main body 123 to rotate and / or move, and the main body 123 causes the pressing part 121 and the clearance part 122 to move, thereby switching the state of the second limiting member 120. The protrusion of the operating parts 125 relative to the main body 123 significantly improves the convenience of user operation and enhances the user experience.

[0105] Specifically, see Figure 7The operating section 125 has two parts. When the second limiting member 120 rotates in the horizontal direction ( Figure 7 When the second limiting member 120 is rotatably disposed on the connecting structure 200 in the X direction, the two operating parts 125 are arranged at intervals along the height direction of the column 300; when the second limiting member 120 is rotatably disposed on the connecting structure 200 around the height direction of the column 300, the two operating parts 125 are arranged at intervals along the horizontal direction; when the second limiting member 120 is movably installed on the connecting structure 200 along the height direction of the column 300, the two operating parts 125 are arranged at intervals along the height direction of the column 300.

[0106] Preferably, the outer surface of the operating part 125 is an arc-shaped surface, which helps to reduce the friction between the user's hand and the operating part 125, improve the convenience of user operation, and enhance the user's experience.

[0107] In this embodiment, a soft rubber layer is provided on the abutment 121. In the first locking state, the abutment 121 abuts against the column 300 through the soft rubber layer. This arrangement can prevent hard contact between the abutment 121 and the column 300, prevent damage to the abutment 121 and the column 300, and improve the service life of the abutment 121 and the column 300.

[0108] For example, the soft rubber layer is made of rubber and is bonded or vulcanized to the side of the abutment 121 facing the column 300.

[0109] In other embodiments, see Figure 6 and Figure 7 The bracket also includes a bushing 130 located within the mounting hole 220. The bushing 130 is fitted onto the column 300, and the bushing 130 is provided with a deformable part 131. In the first locked state, the abutting part 121 abuts against the column 300 through the deformable part 131. This arrangement can prevent hard contact between the abutting part 121 and the column 300, prevent damage to the abutting part 121 and the column 300, and improve the service life of the abutting part 121 and the column 300.

[0110] For example, the deformable part 131 is made of rubber.

[0111] In some embodiments, see Figure 6 and Figure 7 The mounting hole 240 is provided on the wall of the mounting hole 220. The second limiting member 120 is movably disposed in the mounting hole 240 so that the user can operate the operating part 125 on the side of the connecting structure 200 away from the column 300, and the abutting part 121 of the second limiting member 120 can abut against the column 300.

[0112] Specifically, see Figure 7The connecting structure 200 is provided with an assembly hole 220, and the mounting hole 240 is provided on the wall of the assembly hole 220.

[0113] In some embodiments, see Figure 6 and Figure 7 A third limiting member 210 is provided on the connecting structure 200. In the second locked state, the second limiting member 120 abuts against the third limiting member 210 to limit the second limiting member 120 to the second locked state. The second limiting member 120 can no longer move relative to the column 300 and the connecting structure 200, which improves the stability of the second limiting member 120 in the second unlocked state.

[0114] Specifically, see Figure 5 , Figure 6 and Figure 7 The second limiting member 120 is rotatably disposed in the connecting structure 200 about the X direction, and the third limiting member 210 is disposed in the mounting hole 240. In the second locking state, the surface of the main body 123 on the side away from the operation part 125 abuts against the third limiting member 210 to limit the second limiting member 120 to the second locking state.

[0115] In this embodiment, see Figure 6 and Figure 7 The third limiting member 210 is provided with a groove 211. When the second limiting member 120 switches between the second unlocked state and the second locked state, the main body 123 drives the relatively protruding pressing part 121 to move. At least part of the pressing part 121 can enter the groove 211. The groove 211 provides space for the movement of the pressing part 121, effectively avoiding the influence of the third limiting member 210 on the movement of the pressing part 121.

[0116] In another alternative embodiment, the second limiting member 120 is movably mounted on the column 300.

[0117] In this embodiment, the structure of the second limiting member 120 can be the same as that when it is installed on the connecting structure 200, and will not be described again here.

[0118] In this embodiment, the switching action of the second limiting member 120 can be the same as its switching action when it is installed on the connecting structure 200, which will not be described again here.

[0119] Optionally, see Figure 8 The bracket also includes a mounting component 140, and the connection structure 200 includes a connecting arm. The mounting component 140 is fixedly or movably disposed on the connecting arm for supporting the display device and / or audio device.

[0120] In this embodiment, see Figure 8The mounting assembly 140 includes a support plate 141 and a protective plate 142 disposed on the support plate 141. The support plate 141 is connected to the connecting arm and is used to support the display device and / or audio device. The protective plate 142 can be located around the display device and / or audio device to prevent the display device and / or audio device from falling off the support plate 141, thereby improving the safety of the bracket.

[0121] For example, when the mounting assembly 140 is fixedly mounted on the connecting arm, the support plate 141 is fixedly connected to the connecting arm by bolts. When the mounting assembly 140 is movably mounted on the connecting arm, the support plate 141 is rotatably connected to the connecting arm by a pin.

[0122] Display devices include, but are not limited to, tablet computers and computer screens, and audio devices include, but are not limited to, speakers and microphones.

[0123] The above description is only a specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Those skilled in the art should understand that any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present utility model fall within the protection and disclosure scope of the present utility model.
