Description

Technical Field

[0001] The utility model relates to the technical field of display mounting brackets, in particular to a load-bearing head structure of a display bracket. Background Art

[0002] The load-bearing structure of a display bracket is the most core part of the bracket design, which directly determines the stability, adjustability and load-bearing capacity of the bracket. In the prior art, in order to achieve multi-angle adjustment, a cantilever bracket is mostly used to fix the display. The cantilever is connected by a hinge or a bearing, and the stability and load-bearing capacity of its load-bearing part have become the main technical difficulties at present.

[0003] In the prior art, the adjustment and locking of the angle of the load-bearing part rely on friction, but it is more difficult to adjust the upward pitch angle. To solve this problem, for example, the Chinese utility model patent with the publication number CN219432863U discloses a pitch adjustment component for a display bracket and a display bracket on July 28, 2023. An elastic member is arranged between the fixed structure and the adjusting member. When the adjusting member rotates relative to the mounting structure, the elastic member can provide rotational assistance, so that it is more labor-saving for the user to adjust the angle of the display.

[0004] However, the stability of the above structure is not good. Due to the use of an elastic member for assistance, its load-bearing capacity is also limited. Summary of the Utility Model

[0005] In view of at least one of the above technical problems, the utility model provides a load-bearing head structure of a display bracket, and improves the load-bearing capacity and stability of the bracket head by structural improvement.

[0006] According to the first aspect of the utility model, a load-bearing head structure of a display bracket is provided, including:

[0007] A fixing plate for fixedly connecting with the mounting surface of the display bracket;

[0008] A support frame connected to the fixing plate, and the support frame has a support wall extending parallel in a direction away from the fixing plate;

[0009] A head connection component, including a head connecting piece with one end arranged between the two support walls and a one-way bearing fixed on the head connecting piece. A rotating shaft that can rotate unidirectionally relative to the head connecting piece is arranged in the one-way bearing;

[0010] A connection adjustment component, including a fixed washer coaxially fixed at both ends of the rotating shaft, a pressing piece docked with the fixed washer, a head fixing piece for fixing the pressing piece on the support wall, and a fastener axially passing through the support wall, the head fixing piece, the pressing piece, the fixed washer and the rotating shaft;

[0011] Wherein, the rotating shaft can rotate freely when the head connecting piece rotates from bottom to top, and the fastener is used to adjust the frictional force between the fixing washer and the pressing piece.

[0012] In some embodiments of the present utility model, the support frame and the fixing plate are relatively rotatably connected, and the support frame further has a locking structure connected to the fixing plate.

[0013] In some embodiments of the present utility model, the support frame further includes a main panel connected between the same end faces of the two support walls, the main panel is rotatably connected to the fixing plate, and the locking structure includes an arc-shaped hole provided on the main panel and a locking screw passing through the arc-shaped hole and screwed to the fixing plate.

[0014] In some embodiments of the present utility model, both end faces of the rotating shaft are provided with polygonal prisms protruding coaxially, and the surface of the fixing washer facing the rotating shaft is provided with correspondingly arranged polygonal grooves.

[0015] In some embodiments of the present utility model, the surface of the fixing washer opposite to the pressing piece has corresponding conical protrusions and flared grooves, and the conical protrusions and flared grooves are configured such that after coming into contact with each other, as the pressure increases, the contact area also increases.

[0016] In some embodiments of the present utility model, the conical protrusions and the flared grooves are annular and are provided with at least one interval.

[0017] In some embodiments of the present utility model, the surface of the pressing piece facing away from the fixing washer has a protruding positioning portion, and the support wall has a positioning groove adapted to the positioning portion.

[0018] In some embodiments of the present utility model, the surface of the pressing piece facing away from the fixing washer also has a plurality of positioning holes, and the head fixing member has positioning posts passing through the support wall and extending into the positioning holes. There are at least two positioning posts, and they are evenly distributed in the circumferential direction.

[0019] In some embodiments of the present utility model, the head fixing member is detachably connected to the two mutually opposite sides of the support wall, and the side of the head fixing member away from the support wall further has a boss. The fastener includes a bolt and a nut, and one of the two bosses further has an anti-rotation groove for preventing the nut from rotating.

[0020] In some embodiments of the present utility model, the head connecting member further has a limiting protrusion, and the limiting protrusion is configured to abut against the support frame when the head connecting member rotates to a set angle.

[0021] The beneficial effects of the present utility model are as follows: The rotation of the rotating shaft in the present utility model is a one-way rotation from bottom to top, and there is friction between the fixed washer and the pressing member. Compared with the conventional one-way bearing structure, the setting of this structure enables part of the force to be borne by the one-way bearing and another part of the force to be transmitted to the fixed washer and the pressing member when bearing weight. This kind of structure setting has a lower production cost, and also makes the load-bearing capacity of the display bracket stronger and the effect more stable. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which the present invention belongs. The terms used in the description of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0035] Such as Figures 1 to 8The load-bearing head structure of the display bracket shown includes: a fixing plate 1, a support frame 2, a head connection component 3, and a connection adjustment component 4. The fixing plate 1 is used for fixedly connecting with the installation surface of the display bracket; the support frame 2 is connected to the fixing plate 1, and the support frame 2 has a support wall 21 extending parallel in a direction away from the fixing plate 1; the head connection component 3 includes a head connecting piece 31 with one end disposed between the two support walls 21 and a one-way bearing 32 fixed on the head connecting piece 31. A rotating shaft 32a that can rotate unidirectionally relative to the head connecting piece 31 is provided inside the one-way bearing 32; the connection adjustment component 4 includes a fixing washer 41 coaxially fixed to both ends of the rotating shaft 32a, a pressing piece 42 docked with the fixing washer 41, a head fixing piece 43 for fixing the pressing piece 42 on the support wall 21, and a fastener 44 axially passing through the support wall 21, the head fixing piece 43, the pressing piece 42, the fixing washer 41, and the rotating shaft 32a. As Figure 1 and Figure 2As shown, the support wall 21 on the support frame 2 provides additional structural support and serves as a foundation for mounting and fixing other components of the display load-bearing head. The design of the parallel extension of the support wall 21 can disperse the weight of the display, making the overall structure more stable. One end of the head connection assembly 3 is mounted between the support walls 21 to connect the display. A one-way bearing 32 is mounted on the head connecting member 31. A rotating shaft 32a is accommodated in the one-way bearing 32 and can rotate freely in one direction to ensure the stability of the display. The head connecting member 31 can be directly sleeved on other display connection components, facilitating installation. Fixed washers 41 are mounted at both ends of the rotating shaft 32a and are coaxially connected to the rotating shaft 32a. The pressing member 42 provides a fastening function by butting against the fixed washer 41. The pressing member 42 acts on the butting surface of the fixed washer 41 to make the connection tighter. The head fixing member 43 is mounted on the support wall 21 to ensure that the rotating shaft 32a maintains the correct position in the structure and allows controlled rotation. The fastener 44 is the core connecting member in the embodiment of the present invention. It passes through the support wall 21, the head fixing member 43, the pressing member 42, the fixed washer 41, and the rotating shaft 32a, and finally firmly combines the entire structure together. The fastener 44 provides the integrity and strength of the structure and prevents loosening between components. Among them, the rotating shaft 32a can rotate freely when the head connecting member 31 rotates upward from bottom to top. The fastener 44 is used to adjust the friction between the fixed washer 41 and the pressing member 42. When the user adjusts the angle of the display or the bracket, the rotating shaft 32a can rotate unobstructedly in this specific direction, improving the flexibility and convenience of use. The direction of free rotation is limited to upward from bottom to top, which is related to the design of the one-way bearing 32. The one-way bearing 32 only allows the rotating shaft 32a to rotate freely in one direction and restricts rotation in the opposite direction, preventing the display from accidentally changing its position due to gravity or other external forces, ensuring the stability and accuracy of the display after adjustment. The fastener 44 has a dual function. It is not only the main part of the structural connection but also plays a role in adjusting the friction between the fixed washer 41 and the pressing member 42. By adjusting the tightness of the fastener 44, the friction between the fixed washer 41 and the pressing member 42 can be changed. This change in friction directly affects the rotational resistance of the rotating shaft 32a. When the fastener 44 is tightened, the friction increases, and the rotation of the rotating shaft 32a becomes more restricted and stable, preventing the display from moving easily; when the fastener 44 is loosened, the friction decreases, and the rotating shaft 32a rotates more freely, facilitating the user to adjust the angle of the display. It should be understood here that the adjustment of the friction provides the user with greater freedom of control. By changing the friction, the user can choose the rotational flexibility of the display according to needs.

[0036] In some embodiments of the present invention, the support frame 2 and the fixed plate 1 can be relatively rotatably connected, and the support frame 2 further has a locking structure 22 connected to the fixed plate 1. As Figure 3As shown, the connection between the support frame 2 and the fixed plate 1 is not only fixed but also has the function of relative rotation. The relative rotational connection provides higher adjustability for the monitor bracket, especially when adjusting at multiple angles or using it in multiple positions, enhancing the convenience and flexibility of use. The locking structure 22 can lock the support frame 2 relative to the fixed plate 1 after the user adjusts it to the desired angle or position, thus ensuring that the monitor remains stable during use and will not shift in position due to external forces or gravity.

[0037] Furthermore, the support frame 2 further includes a main panel 23 connected between the same end faces of the two support walls 21. The main panel 23 is rotatably connected to the fixed plate 1. The locking structure 22 includes an arc-shaped hole 22a provided on the main panel 23 and a locking screw 22b that passes through the arc-shaped hole 22a and is screwed to the fixed plate 1. Please continue to refer to Figure 3 , the main panel 23 connects the two support walls 21 on both sides together, enhancing the structural strength and stability of the entire support frame 2. The main panel 23 and the fixed plate 1 are rotatably connected, which means that the main panel 23 can rotate relative to the fixed plate 1 within a certain range. The arc-shaped hole 22a can provide a certain range of rotation trajectories, allowing the main panel 23 to adjust the angle relative to the fixed plate 1. Through this arc-shaped design, when the user adjusts the angle of the support frame 2, the main panel 23 moves along the trajectory of the arc-shaped hole 22a, thereby changing the angle of the monitor. The locking screw 22b passes through the arc-shaped hole 22a by screwing and is connected to the fixed plate 1. When the user adjusts to the appropriate angle, the locking screw 22b can be tightened to lock the main panel 23 relative to the fixed plate 1 at the current angle to prevent it from displacing again. The combination of the arc-shaped hole 22a and the locking screw 22b makes the structure adjustable and stable. During use, the user can first loosen the locking screw 22b, adjust the position of the main panel 23, and make it move freely within the range of the arc-shaped hole 22a; after adjusting to the appropriate position, tighten the screw to fix it and ensure that the angle will not change. The main panel 23 not only strengthens the overall structural strength of the support frame 2 but also forms an adjustable bracket angle adjustment system with the fixed plate 1 through the rotational connection. The locking structure 22 provides a flexible angle adjustment mechanism through the design of the arc-shaped hole 22a and the locking screw 22b. The arc-shaped hole 22a allows the main panel 23 to rotate within a certain angle range, while the locking screw 22b realizes the locking of the adjusted angle through screwing.

[0038] In some embodiments of the present utility model, both end faces of the rotating shaft 32a are provided with polygonal prisms protruding coaxially, and the surface of the fixed washer 41 facing the rotating shaft 32a is provided with correspondingly arranged polygonal grooves. As Figure 4 and Figure 5As shown, the two ends of the rotating shaft 32a are not simple cylinders or planes, but are connected to other components through raised polygonal prisms. The coaxial setting can ensure that the rotating shaft 32a and the components connected to it maintain precise concentricity during rotation without offset. The polygonal structure of the prism increases the torsional strength of the rotating shaft 32a. When it is combined with other components, it can prevent the rotating shaft 32a from sliding or rotating uncontrollably under load or external force, thereby improving the stability and reliability of the system. The polygonal structure is not limited to the shape shown in the figure and can also be a hexagon, an octagon, etc. Corresponding to the polygonal prism of the rotating shaft 32a, the surface of the fixed washer 41 facing the rotating shaft 32a is provided with a polygonal groove, and the shape of this groove matches the polygonal prism at the end of the rotating shaft 32a to ensure that the two can be closely combined. The polygonal groove and the prism of the rotating shaft 32a are mutually engaged. Both are polygonal structures, and the rotating shaft 32a will not slide in the washer during assembly, and the anti-slip and anti-rotation effects are generated through shape matching.

[0039] In another embodiment of the present utility model, the surface of the fixed washer 41 opposite to the pressing member 42 has corresponding tapered protrusions 42a and flared grooves 41a. The tapered protrusions 42a and the flared grooves 41a are configured such that after coming into contact with each other, as the pressure increases, the contact area also increases. As Figure 6 shown, a special geometric structure is adopted between the fixed washer 41 and the pressing member 42. One has tapered protrusions 42a, and the other has corresponding flared grooves 41a, so that the two can be precisely fitted together during assembly. The tapered protrusion 42a is in the shape of a similar cone, with a pointed top and a wide bottom. This shape helps to gradually increase the contact surface. With the action of pressure, the protruding part can gradually press into the groove. The flared groove 41a is fully matched with the tapered protrusion 42a to form a relatively stable joint surface. When the tapered protrusion 42a contacts the flared groove 41a, as the pressure increases, the contact area between the two will gradually increase. Initially, only the top of the tapered protrusion 42a contacts the bottom of the flared groove 41a. As the pressure continues to increase, a larger part of the protrusion begins to contact the inner wall of the groove, thereby increasing the contact area. This gradually increasing contact area effectively disperses the stress points, reduces local stress concentration, and enhances the overall load-bearing capacity and stability. This setting makes the contact surface smaller when the force is small, which is convenient for adjustment and movement; when fixation or stability is required, after applying pressure, the contact surface increases, providing stronger friction and locking force.

[0040] Specifically, the conical protrusions 42a and the flared grooves 41a are annular, and at least one set is provided at intervals. The geometric shapes of the conical protrusions 42a and the flared grooves 41a are arranged in an annular manner, and these structures are distributed in a ring around the central axis of the rotating shaft 32a. The annular design can evenly distribute the stress points. Compared with single-point or linear contact, the annular structure can better bear pressure and disperse the load, avoid local stress concentration, be more stable when stressed, and enable the structure to remain stable under a large load. The setting of at least one set indicates that the annular structure of the conical protrusions 42a and the flared grooves 41a is not single and multiple sets can be set. By increasing the number of annular structures, the contact area and load-bearing capacity are further increased. The annular conical protrusions 42a and the flared grooves 41a are provided at intervals, which means they are not continuous but have a certain gap. The advantage of the interval distribution is that the stress can be evenly distributed among multiple stress points, thereby reducing stress concentration in local areas. At the same time, the interval setting can also reduce friction and reduce the operating resistance when adjustment is needed, making the system more flexible during adjustment and adapting to changes in different angles or positions.

[0041] Furthermore, the surface of the pressing member 42 facing away from the fixed washer 41 has a protruding positioning portion 42b, and the support wall 21 has a positioning groove 21a adapted to the positioning portion 42b. As Figure 7 shown, the positioning portion 42b can be protrusions of various shapes, such as circular, square or wedge-shaped, providing a mechanical positioning point to ensure that the pressing member 42 can be aligned with other components during assembly and prevent position deviation or misalignment. The shape of the positioning groove 21a exactly matches that of the positioning portion 42b, ensuring seamless docking between the two. During the assembly process, the positioning groove 21a provides a guiding function to ensure that the pressing member 42 can smoothly and accurately fall into the correct position of the support wall 21 when installed. This structure can also prevent relative sliding or rotation during use, contributing to the stability of the mechanical structure.

[0042] Further, the surface of the pressing member 42 facing away from the fixed washer 41 also has a number of positioning holes 42c, and the head fixing member 43 has positioning posts 43a that pass through the support wall 21 and extend into the positioning holes 42c. There are at least two positioning posts 43a, and they are evenly distributed in the circumferential direction. Please continue to refer to Figure 7 , the multiple positioning holes 42c provide multiple fixing points. The positioning posts 43a pass through the support wall 21 and are inserted into the positioning holes 42c of the pressing member 42, playing a role in precise positioning and fixing. The positioning posts 43a are evenly distributed in the circumferential direction, ensuring that the positioning posts 43a are symmetrically distributed on the pressing member 42, making the force more evenly distributed, preventing the structure from tilting or rotating when subjected to external forces, and ensuring the relative position of the pressing member 42 and the head fixing member 43 remains stable without displacement or loosening.

[0043] In some embodiments of the present utility model, the head fixing member 43 is detachably connected to two mutually opposite sides of the support wall 21, and a boss 43b is further provided on the side of the head fixing member 43 away from the support wall 21. The fastener 44 includes a bolt 44a and a nut 44b, and an anti-rotation groove 43c for preventing the nut 44b from rotating is further provided on one of the two bosses 43b. As Figure 8 shown, the head fixing member 43 can be easily detached and reinstalled during installation or maintenance, providing greater flexibility for the device and facilitating adjustment and maintenance. The head fixing member 43 can be installed on either side of the two sides of the support wall 21, providing a wider range of adaptability and assembly flexibility. The function of the boss 43b is to form a mechanical base during installation to help form a stable connection between the bolt 44a and the nut 44b. The fastener 44 is composed of a bolt 44a and a nut 44b, which is responsible for firmly connecting the head fixing member 43 to the support wall 21. The bolt 44a passes through the support wall 21 and other components, clamping the various structures together. Among the two bosses 43b on both sides, an anti-rotation groove 43c is designed on one of the bosses 43b to prevent the nut 44b from rotating. When the nut 44b is tightened or loosened, the anti-rotation groove 43c can catch the nut 44b and prevent it from rotating together with the bolt 44a. The anti-rotation groove 43c is designed according to the shape of the nut 44b and matches the outer shape of the nut 44b.

[0044] Furthermore, a limit protrusion 31a is further provided on the head connecting member 31, and the limit protrusion 31a is configured to abut against the support frame 2 when the head connecting member 31 rotates to a set angle. As Figure 2 shown, the main function of the limit protrusion 31a is to limit the rotation angle of the head connecting member 31. When the head connecting member 31 rotates to the set angle during operation or adjustment, the limit protrusion 31a will contact the support frame 2 to prevent further rotation, ensuring that its movement range is within the safe and designed limits. This structural design prevents the head connecting member 31 from being damaged due to excessive rotation or affecting the normal use of the device. It should be noted here that the set angle is the maximum rotation angle allowed during the operation of the device. The limit protrusion 31a ensures this angle by contacting the support frame 2, and the size of this angle can be customized according to the usage scenarios of different devices. The limit protrusion 31a is provided at a certain position on the head connecting member 31, usually corresponding to a certain part of the support frame 2. When the head connecting member 31 rotates or tilts, the limit protrusion 31a will move along with it. When the head connecting member 31 rotates to the set angle, the limit protrusion 31a will abut against a certain part of the support frame 2, and this form of contact plays a physical limiting role to prevent the head connecting member 31 from continuing to rotate. This structure is very practical in devices that need to frequently adjust the angle, which can not only ensure the freedom of operation but also ensure the safety and durability of the device.
