Description

Technical Field

[0001] The present application relates to the technical field of brackets, and in particular to a bracket connection structure and a display bracket. Background Art

[0002] In the modern display technology landscape, large monitors like televisions have become indispensable devices in daily life and commercial applications. As monitors continue to increase in size and weight, the design of compatible monitor stand connection structures has become increasingly critical. Traditional metal connectors, used as the connection between support arms and mounting heads, have exposed numerous limitations.

[0003] Among them, metal connectors are usually dense, which significantly increases the weight of the entire monitor stand, making installation and movement difficult. This is especially true in weight-sensitive applications, such as wall-mounted installations or movable display racks. Overweight brackets may cause excessive pressure on the installation surface and even pose a safety hazard. In addition, the characteristics of metal determine that its ability to absorb stress vibrations is relatively weak. Various stress vibrations are inevitably generated during the frequent installation and disassembly of large monitors and the angle adjustment during daily use. Since metal connectors cannot effectively absorb and disperse these stresses, fatigue cracks are very likely to occur in areas where stress is concentrated, causing the metal connectors to break, seriously affecting the stable support of the monitor, and may cause safety accidents such as the monitor falling, resulting in huge economic losses to users.

[0008] Further preferably, the surface of the bushing is coated with a protective structure. Specifically, the bushing is a carbon steel bushing, and the protective structure is a copper powder coating layer and / or a PTFE coating layer.

[0009] Preferably, the bushing is provided with a flanging structure, which blocks the head and tail of the rivet stud tail screw from directly abutting against the outer wall surface of the plastic connector, and the bent end of the flanging structure is chamfered.

[0010] Preferably, the rivet post structure at the tail of the rivet post tail screw is abutted against the flanging structure by being provided with multiple layers of washers.

[0011] Preferably, the first end is provided with a first boss, the first boss protrudes relative to the outer wall surface of the plastic connector, and the flange structure of the bushing is used to abut against the first boss; the second end is passed through and fixed with a connector to be connected to the mounting head, and a second boss is protruded at the position of the connector, and the connector is arranged to abut against the second boss.

[0013] Compared with the prior art, the present invention has the following advantages:

[0014] The plastic connector has high tensile and compressive strengths, and is preferably made of nylon. It has high tensile and compressive strengths, with a higher tensile strength than metal and a compressive strength similar to that of metal. This ensures the overall lightweight nature of the bracket connection structure and optimizes the thickness of the connection between the plastic connector and the support arm to provide good support strength. The plastic connector also has excellent toughness and strong absorption capacity for shock, stress, and vibration. It can withstand the external impact of repeated disassembly and removal of large display devices without breaking easily, ensuring stable support for the display. It can also maintain its original mechanical strength after repeated bending and flexing, adapting to frequent adjustments and extending the service life of the bracket connection structure.

[0015] Specifically, the thickness of the end portion where the plastic connector is connected to the support arm is greater than the thickness of the support arm, thereby ensuring connection strength, avoiding deformation under multiple pitch adjustments, and increasing the weighing range of the bracket connection structure.

DETAILED DESCRIPTION

[0024] Below, the present application is further described in conjunction with specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0025] In the description of this application, it should be noted that for directional words, such as the terms "center", "horizontal", "longitudinal", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise" and so on, the directions and positional relationships indicated are based on the directions or positional relationships shown in the accompanying drawings, which are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and cannot be understood as limiting the specific scope of protection of this application.

[0026] It should be noted that the terms "first", "second", etc. in the description and claims of this application are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0027] The terms "comprises" and "having" and any variations thereof in the specification and claims of this application are intended to cover non-exclusive inclusions. For example, a process, method, system, product or apparatus that includes a series of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, product or apparatus.

[0028] In a preferred embodiment, see Figures 1 to 6 , this application document provides a bracket connection structure 1, including: a support arm 10, a plastic connector 222 and a mounting head 30, the mounting head 30 is used for external electronic equipment, one end of the plastic connector 222 is connected to the support arm 10, so that the plastic connector 222 can be rotated up and down relative to the support arm 10, the other end of the plastic connector 222 is connected to the mounting head 30, so that the mounting head 30 can be swung left and right relative to the plastic connector 222, and the thickness of the end of the plastic connector 222 used for connection to the support arm 10 is greater than the thickness of the support arm 10.

[0029] Among them, the bracket connection structure 1 in the present application document is specifically connected to a larger display electronic device such as a television through the mounting head 30, and the plastic connector 222 is the transition connector 222 between the support arm 10 and the mounting head 30. The plastic connector 222 is rotatably connected to the support arm 10, and the rotation amplitude of the plastic connector 222 relative to the support arm 10 is in the up and down directions, and the left and right directions are fixed and do not participate in the rotation, that is, rotating the plastic connector 222 can drive the mounting head 30 to adjust the up and down pitch angle relative to the support arm 10. Similarly, the plastic connector 222 is rotatably connected to the mounting head 30, and the mounting head 30 can only rotate left and right relative to the plastic connector 222, and the up and down directions are fixed. Then, through the connection of the plastic connector 222, the connecting head can adjust the pitch angle relative to the support arm 10, as well as the left and right angles.

[0030] Furthermore, the plastic connector 222 in the present application document is specifically a plastic connector 222 made of nylon material, which has high tensile and compressive strength, and its tensile strength is higher than that of metal, and its compressive strength is similar to that of metal. Therefore, in the present application document, the transition connector 222 between the support arm 10 and the mounting head 30 preferably adopts a plastic connector 222 made of nylon material, which can have good supporting strength while ensuring the overall lightweight of the bracket connection structure 1. At the same time, since the plastic connector 222 made of nylon has better toughness and strong ability to absorb impact and stress vibration, and since the bracket connection structure 1 in this application document is preferably used to support large display devices such as televisions, it has a larger weighing requirement. The general metal connector 222 has a weaker ability to absorb stress vibration. When a heavier large-scale television device is connected to the mounting head 30, if it is disassembled and removed multiple times, the transition connector 222 made of metal material is prone to breakage. However, in this application document, by using a plastic connector 222 made of nylon material, it can withstand the external force impact of multiple disassembly of large display devices, is not prone to breakage, and ensures stable support of the display.

[0031] At the same time, the nylon plastic connector 222 can still maintain its original mechanical strength after repeated bending. For the frequent adjustment actions of the display bracket 2 in daily use, such as pitching up and down, rotating left and right, etc., the nylon transition connector 222 can maintain good performance for a long time and is not easily damaged due to fatigue, thereby extending the service life of the bracket connection structure 1.

[0032] As a preference, the plastic connector 222 includes a first end 21 and a second end 22, the first end 21 is connected to the support arm 10, and the second end 22 is connected to the mounting head 30, and the thickness of the first end 21 is greater than the thickness of the support arm 10; an adjustment component 23 is provided in the first end 21 of the plastic connector 222, and an elastic support member 11 is provided in the support arm 10, and the adjustment component 23 is connected to the elastic support member 11, and the support strength of the support arm 10 is changed by adjusting the adjustment component 23.

[0033] Specifically, since the plastic connector 222 is made of plastic material, such as nylon, the structural strength of the plastic connector 222 needs to be ensured. Figure 4 , taking the up and down direction as a reference, the distance between the upper cover and the lower cover of the support arm 10 is the first thickness X1, and the distance between the upper surface and the lower surface of the first end 21 of the plastic connector 222 is the second thickness X2. The first thickness X1 is less than the second thickness X2, thereby ensuring that the connection strength between the first end 21 and the support arm 10 of the plastic connector 222 is high. Due to the pitch adjustment function borne by the first end 21, the second thickness X2 of the first end 21 is greater than the first thickness X1 of the support arm 10, which can prevent the plastic connector 222 from being deformed under multiple pitch adjustments, thereby ensuring the connection stability of the plastic connector 222.

[0034] Therefore, the bracket connection structure 1 in this application document has a relatively large weighing range, and preferably all electronic devices within the range of 5-45 kg can be connected and used through the mounting head 30 .

[0035] As another preferred option, see Figure 2 and Figure 3 The adjustment component 23 includes: a rivet stud tail screw 231, which is fixedly connected to the plastic connector 222 along the thickness extension direction of the first end 21, and the rivet stud tail screw 231 is threadedly connected to the elastic support member 11; the head 236 and the tail 237 of the rivet stud tail screw 231 are both sleeved with a bushing 232, and then the head 236 and the tail 237 of the rivet stud tail screw 231 are against the plastic connector 222 through the bushing 232.

[0036] It should be noted that the rivet post tail screw 231 is a screw with a relatively special structure. Its tail 237 has a structure similar to that of a rivet post, and its diameter is larger than that of the screw body. The main function of this part is to play a fixing role similar to that of a rivet after installation. At the same time, the head 236 in this application document is a hexagonal structure, which makes it convenient for the operator to insert the head 236 through the hexagonal screw and then rotate the rivet post tail screw 231 to adjust the support strength of the elastic support member 11. The elastic support member 11 is specifically a gas spring.

[0037] Therefore, in the present application document, the head 236 and the tail 237 of the rivet post screw 231 are connected to the plastic connector 222 through the bushing 232 structure. At the same time, preferably, the bushing 232 is provided with a flanging structure 2321, and the flanging structure 2321 stops the head 236 and the tail 237 of the rivet post screw 231 from directly against the outer wall surface of the plastic connector 222, so as to avoid the rivet post screw 231 being directly connected to the plastic connector 222, thereby reducing the wear on the plastic connector 222 during the rotation and adjustment of the rivet post screw 231.

[0038] It is further preferred that the surface of the bushing 232 is covered with a protective structure. Specifically, the bushing 232 is a carbon steel bushing 232, and the protective structure is a copper powder coating layer and / or a PTFE coating layer. The bushing 232 made of carbon steel has a high strength in use. The copper powder coating layer and the PTFE coating layer cover the bushing 232, which can improve the wear resistance of the bushing 232 to a certain extent. Moreover, when PTFE (polytetrafluoroethylene) is used as a coating, it is difficult for grease, glue or other sticky substances to adhere to its surface, so as to optimize and reduce the rotational wear between the bushing 232 and the plastic connector 222. At the same time, when the bushing 232 coated with a PTFE coating layer is used in conjunction with the plastic connector 222 made of nylon, since the nylon surface is smooth and the friction coefficient is small, it has self-lubricating properties when used as a transition connector 222. Therefore, when the bushing 232 rotates relative to the surface of the plastic connector 222, it can effectively reduce friction resistance, reduce noise, improve the user experience when adjusting the display, and reduce the loss of the plastic connector 222.

[0039] The bent end of the flange structure 2321 is provided with a chamfer 2322 . The chamfer 2322 can reduce the wear caused when the thread of the rivet stud 231 passes through the bushing 232 .

[0040] Preferably, the rivet column structure of the tail 237 of the rivet column tail screw 231 is backed by multiple layers of washers and the flange structure 2321, wherein the washers in this application document are preferably a layer of metal washers 233 and a layer of spring washers 234, the spring washers 234 are backed against the bushing 232, and the metal washers 233 are superimposed on the spring washers 234. The spring washers 234 can play a certain buffering role, and the metal washers 233 can provide a certain support stability.

[0041] Preferably, the first end 21 is provided with a first boss 235, and the first boss 235 protrudes relative to the outer wall surface of the plastic connector 222, and the flange structure 2321 of the bushing 232 is used to abut against the first boss 235; the second end 22 is fixed with a connector 222 and connected to the mounting head 30, and a second boss 221 is protruded at the position of the connector 222, and the connector 222 is abutted against the second boss 221. The connector 222 is specifically a screw-nut structure, and the position where the first boss 235 and the second boss 221 are set is the position where the rivet stud screw 231 and the screw-nut structure pass through the plastic connector 222 for connection. Therefore, the first boss 235 and the second boss 221 can thicken the connection position of each screw and the screw-nut structure to a certain extent, ensure the connection stability between the plastic connector 222 and the rivet stud screw 231 and the screw-nut structure, and effectively avoid deformation at the connection.

[0042] For further information, see Figure 6 The present application document also provides a display stand 2, which includes: a mounting base 3, and a stand connection structure 1 as described above, wherein the mounting base 3 is connected to the stand connection structure 1.

[0043] In the monitor stand 2, the support arm 10 is provided with a wire management ring 12. Different from the general wire management groove structure, the wire management ring 12 has a larger annular passing area, so that the thicker data cable of the TV connected to the monitor stand 2 can pass through for management, reducing the difficulty of wire management. At the same time, on the side of the mounting head 30, see Figure 4 By superimposing the angle adjustment member 31, the integral gasket 32 and the adapter 33, the mounting head 30 and the plastic connector 222 are firmly connected. One end of the angle adjustment member 31 is connected to the panel of the mounting head 30, and the integral gasket 32 is connected to the angle adjustment member 31 to improve the structural strength of the angle adjustment member 31. One end of the adapter 33 is connected to the integral gasket 32, and the other end is rotatably connected to the plastic connector 222 to ensure that the mounting head 30 as a whole can be rotated left and right relative to the plastic connector 222.
