[0004] The above-mentioned monitor bracket, the existing hanging plate has the function of free pitch and swing, which is realized by the cooperation of the first connecting block and the U-shaped connecting piece, and the support is formed by the friction between the shaft hole and the inner wall of the rotating shaft at the hinge. As a result, when the locking force after rotation is too small, the positioning effect of the monitor is not good. When the locking force is too large, it leads to difficulty in adjustment and poor stability in use, which needs to be improved. Summary of the invention

[0005] In order to improve the problem of poor stability in use caused by too small or too large locking force during the rotation of the hanging plate, the technical solution provides a display stand swing head adjustment structure.

[0006] The purpose of this technical solution is achieved in this way:

[0007] A monitor stand swing adjustment structure, comprising an adjustment arm and a connecting rotating head, an adjustment structure is arranged between the adjustment arm and the connecting rotating head, the adjustment structure comprises a first connecting member and a second connecting block, the connecting rotating head is connected to the first connecting member, the adjustment arm is connected to the second connecting block, the first connecting member is provided with a locking member, and the locking member enables the first connecting member to be hinged with the second connecting block;

[0008] The adjustment structure is provided with a torsion spring, which is respectively connected between the first connecting member and the second connecting block. The elastic force of the torsion spring makes the connecting rotating head tend to swing upward. The adjustment structure is also provided with a friction member, which is used to increase the swing resistance.

[0009] Through the above technical solution, when the monitor stand swing head adjustment structure is in normal use, the connecting swivel is used for installing monitors and other equipment, and the adjusting arm supports the connecting swivel to maintain a certain height, so that the monitor has the function of height adjustment, and the connecting swivel is rotatably connected to the first connecting member in the adjustment structure, so that the rotating joint has a rotation function to adjust the steering angle of the monitor, and the first connecting member and the second connecting block are hinged through a locking member, so that the connecting swivel can be rotated up and down to realize the vertical swing of the monitor, and the adjusting arm is hinged to the second connecting block, so that the connecting swivel can be rotated left and right to realize the horizontal swing of the monitor, and the monitor is adjusted to a suitable angle and height through the adjustment structure, thereby improving the flexibility and freedom of monitor adjustment.

[0010] The elastic force of the torsion spring acts on the first connecting member and the second connecting block at the same time. The elastic force can directly act on the connecting rotating head, thereby providing a continuous and stable upward swinging trend. The friction member increases the roughness of the rotating contact surface, thereby improving the swinging resistance, so that the display maintains a relatively stable position during adjustment. The friction member and the torsion spring cooperate to form a reset effect, making the adjustment easier and the positioning stability better after adjustment.

[0011] Preferably, the second connecting block is provided with an installation groove 1 and an installation groove 2, and the installation groove 1 and the installation groove 2 are located in a one-to-one correspondence on opposite side walls of the second connecting block along the hinge axis, the torsion spring is arranged in the installation groove 1, and the friction member is arranged in the installation groove 2, and the friction members are respectively abutted between the first connecting member and the bottom of the second installation groove.

[0012] Through the above technical solution, the torsion spring and the friction member are respectively embedded in the mounting groove 1 and the mounting groove 2 of the second connecting block in a one-to-one correspondence, ensuring that the elastic force of the torsion spring can effectively act on the first connecting member. The torsion spring is built-in to limit the swing and displacement of the torsion spring. The friction member is respectively against the side wall opposite to the bottom of the second mounting groove and the first connecting member through the friction resistance surfaces on both sides to provide friction resistance.

[0013] Preferably, the friction member comprises a friction plate 1 and a friction plate 2, the number of the friction plate 1 is the same as the number of the friction plate 2, and the friction member is formed by staggeredly stacking a plurality of the friction plates 1 and a plurality of the friction plates 2.

[0014] Through the above technical scheme, two friction plates one and two friction plates two are stacked in an interlaced manner to form a friction part. The friction plate one can be a POM friction plate, which has high wear resistance and good self-lubrication. The friction plate two can be a metal friction plate, which has high hardness and compressive strength. The friction plates made of these two materials are stacked and used in an interlaced manner to ensure the service life of the friction part and significantly improve its friction force, thereby improving the performance of the friction part to be more stable.

[0015] Preferably, a positioning groove is provided on the inner wall of the second installation groove, and a positioning portion is provided on the first friction plate. The positioning portion is arranged in a one-to-one correspondence with the positioning groove, and the positioning portion is embedded in the corresponding positioning groove for rotation limitation.

[0016] Through the above technical scheme, the opening of the positioning groove along the embedding direction of the friction part contacts the positioning portion of the friction plate one, the shape of the positioning portion matches the positioning groove, and the positioning portion slides along the positioning groove after being embedded in the positioning groove one by one, so that when the friction plate one is embedded in the mounting groove two, the rotation of the friction plate one is restricted, so that the friction plate one and the friction plate two form relative rotation to achieve interaction, thereby providing damping and resistance.

[0017] Preferably, the first connecting member is provided with a protective cover, and two protective covers are provided, and the two protective covers are arranged on opposite sides of the first connecting member along the hinge axis in a one-to-one correspondence.

[0018] Through the above technical solution, the protective covers installed on both sides of the first connecting member will not interfere with the second connecting block when rotating. The protective covers effectively isolate external dust, dirt and other impurities from invading the mounting groove one and the mounting groove two, reduce the wear of parts and performance degradation caused by impurities, and improve protection.

[0019] Preferably, the locking member includes a locking screw and a locking nut, the locking screw passes through the first connecting member and the second connecting block and is connected to the locking nut, the locking nut has an edge structure, and the friction plate 2 is provided with a limiting hole adapted to the edge structure.

[0020] Through the above technical solution, the locking member is composed of a locking screw and a locking nut. The locking screw passes through the adjustment structure and one end of the locking screw abuts against a side end face of the first connecting member corresponding to the installation groove. The other end of the locking screw is threadedly connected to the locking nut to avoid over-tightening affecting normal rotation, so that the positions of the first connecting member and the second connecting block are relatively fixed after connection, and each friction plate is in a state of being pressed and rubbed.

[0021] The locking nut has an edge structure, which makes the locking nut hexagonal in shape. A limiting hole is opened in the locking nut corresponding to the friction plate 2. The shape and size of the limiting hole are adapted to the edge structure, so that after the locking nut passes through the limiting hole, the edge structure forms resistance when rotating, thereby transmitting the rotational motion to the friction plate 2 so that it rotates relative to the friction plate 1, further improving the stability of the friction force generated.

[0022] Preferably, the side wall of the second connecting block is provided with an embedding groove, the torsion spring is embedded in the embedding groove, and the adjustment structure is further provided with a protective cover;

[0023] There are two protective covers, which are arranged one by one on opposite sides of the first connecting member along the hinge axis. The protective cover is provided with a fixing groove, and the second connecting block has a fixing portion, which is embedded in the fixing groove for limiting position.

[0024] Through the above technical solution, the torsion spring is embedded in the embedding groove of the second connecting block to ensure that the elastic force of the torsion spring can effectively act on the first connecting member. The protective covers installed on both sides of the first connecting member are aligned with the fixing part through the fixing groove, so that when the first connecting member rotates, the position of the protective cover is fixed relative to the second connecting part. The protective cover effectively limits the intrusion of external dust, dirt and other impurities into the embedding groove, reduces the performance degradation of parts due to wear of impurities, and improves protection.

[0025] Preferably, the friction part includes a gasket part and a friction part, the friction part abuts between the first connecting part and the gasket part, the protective cover abuts against a side end surface of the gasket part away from the friction part, and the gasket part has a limiting part, which is embedded in the fixing part.

[0026] Through the above technical solution, the gasket part is located between the friction part and the protective cover to provide a plane for friction contact. The gasket part is embedded in the fixing part through the limiting part, so that the position of the gasket part and the second connecting block remains fixed. The two side surfaces of the friction part are respectively abutted against the gasket part and the end surface of the first connecting member that is away from the embedding groove, so that the friction part provides stable friction force during rotation to increase the resistance after rotation adjustment.

[0027] Preferably, the friction portion has a positioning column on one side close to the protective cover, the protective cover is provided with a positioning hole, and the positioning columns pass through the gasket portion one by one and are embedded in the positioning hole for fixation.

[0028] Through the above technical solution, the positioning column is fixed on the friction part and corresponds to the position of the positioning hole one by one. After the positioning column passes through the corresponding positioning hole, the position of the friction part relative to the protective cover is fixed, and then the position of the friction part relative to the second connecting block is fixed, so that when the first connecting member rotates, the gasket part and the friction part are driven to rotate synchronously, so that the friction part rotates relative to the side wall of the first connecting member to form friction resistance.

[0029] Preferably, the gasket portion has a threaded hole, the locking member passes through the first connecting member and the second connecting block and is connected to the threaded hole, and the protective cover is provided with a clearance hole for the locking member to pass through.

[0030] Through the above technical solution, the clearance hole opened on the protective cover provides a channel for the locking piece to pass through. The locking piece passes through the adjustment structure and one end of the locking piece rests against one side end face of the corresponding embedding groove of the protective cover. The other end of the locking piece is threadedly connected to the threaded hole of the gasket part to avoid over-tightening affecting normal rotation, so that the positions of the first connecting piece and the second connecting block are relatively fixed after connection, and the friction piece is in a state of being compressed and having friction resistance.

[0031] Compared with the prior art, the technical solution has the following outstanding and beneficial technical effects:

[0032] 1. The technical solution is to open a mounting groove 1 and a mounting groove 2 on the opposite side walls of the second connecting block, the torsion spring is embedded in the mounting groove 1, and the friction member is embedded in the mounting groove 2. The elastic force of the torsion spring makes the connecting head have a tendency to swing upward continuously and stably, and the friction member increases the swing resistance of the rotating contact. The friction member and the torsion spring cooperate to form a reset effect, so that the display can maintain a relatively stable position when adjusted, making the adjustment easier and the positioning stability better after adjustment.

[0033] 2. The technical solution realizes height adjustment of the display through an adjusting arm. An adjusting structure is provided between the adjusting arm and the connecting rotating head.

The connecting swivel 2 is rotatably connected to the first connecting member 31, so that the display The rotation angle can be adjusted along the rotation axis. The second connecting block 32 is embedded in the U-shaped groove of the first connecting member 31. The two ends of the second connecting block 32 are respectively hinged to the adjusting arm 1 and the first connecting member 31. The hinge axis of the second connecting block 32 and the first connecting member 31 is perpendicular to the rotation axis of the connecting head 2. Through the hinge relationship, the display follows the first connecting member 31 to swing up and down in the vertical direction. The hinge axis of the second connecting block 32 and the adjusting arm 1 is vertically perpendicular to the hinge axis of the second connecting block 32 and the first connecting member 31. Through the hinge relationship, the display follows the second connecting block 32 to achieve left and right swing adjustment.

[0045] See also Figure 3 and Figure 4The second connecting block 32 is provided with a mounting groove 1 6 and a mounting groove 2 7. The mounting groove 1 6 and the mounting groove 2 7 are correspondingly provided on the opposite side end surfaces of the second connecting block 32 along the hinge axis of the first connecting member 31 and the second connecting block 32. The adjustment structure 3 is provided with a torsion spring 4. The torsion spring 4 is arranged in the mounting groove 1 6. The torsion spring 4 is respectively connected between the first connecting member 31 and the second connecting block 32. The elastic force of the torsion spring 4 makes the first connecting member 31 rotate and act on the connecting head 2 to make it have a tendency to swing upward, thereby adjusting the angle of the display to remain stable.

[0046] The adjustment structure 3 is also provided with a friction member 5, which is embedded in the mounting groove 7.

The POM friction plate has high wear resistance and good self-lubrication, and the metal friction plate has high hardness and compressive strength. The two friction plates 1 51 and the two friction plates 2 52 are staggered to form the friction member 5. At this time, one of the friction plates 2 52 abuts against the bottom of the mounting groove 2 7, and the friction plate 1 51 away from the friction plate 2 52 abuts against the opposite side wall of the first connecting member 31, thereby realizing that the friction member 5 abuts between the first connecting member 31 and the bottom of the mounting groove 2 7 respectively, and the friction member 5 is used to increase the swing resistance.

[0047] A positioning groove 9 is provided on the inner wall of the mounting groove 2 7 near the friction plate 1 51. There are four positioning grooves 9. The four positioning grooves 9 are arranged on the inner wall of the mounting groove 2 7 and are evenly spaced along the circumferential direction. The side walls of the two friction plates 1 51 along the circumferential direction are fixed with positioning parts 10 that are compatible with the four positioning grooves 9.

The locking member 11 includes a locking screw 111 and a locking nut 112. The locking nut 112 has an edge structure 13. The locking nut 112 shown in this embodiment forms a hexagonal nut through the edge structure 13. One end of the locking nut 112 with the edge structure 13 passes through the first connecting member 31 and is embedded in the friction member 5. The locking nut 112 abuts against the side wall of the first connecting member 31 corresponding to the friction member 5. The locking screw 111 1 passes through the other side of the adjustment structure 3 and is connected to the locking screw 111, so that the locking member 11 provides a hinge axis. In this embodiment, the first connecting member 31 has a hole that is compatible with the edge structure 13, and the friction plate 52 is provided with a limiting hole 14 that is compatible with the edge structure 13, so that when the first connecting member 31 swings, the locking nut 112 drives the friction plate 52 to rotate at the same time. Based on the fixed position of the friction plate 1 51, the friction plate 52 rotates relative to the friction plate 1 51 to form friction contact, thereby generating friction resistance.

The connecting swivel 2 is rotatably connected to the first connecting member 31, so that the display can be rotated to adjust the angle. The first connecting member 31 is hinged to the second connecting block 32, so that the display can be swung up and down for adjustment. The adjusting arm 1 is hinged to the second connecting block 32, so that the display can be swung left and right for adjustment, which is convenient for adjusting the display to a suitable angle and height and improves the flexibility of adjustment. The adjustment structure 3 is provided with a torsion spring 4, and the elastic force of the torsion spring 4 acts on the first connecting member 31 and the second connecting block 32 at the same time, so that the connecting swivel 2 has a continuous and stable upward swinging tendency, and cooperates with the friction member 5 to increase the roughness of the rotating contact surface, thereby increasing the swinging resistance, so that the display maintains a relatively stable position during the adjustment process, has a reset effect, makes the adjustment easier, and has better positioning stability after adjustment.

[0052] Embodiment 2:

[0053] See also Figure 6 and Figure 7A display stand swing adjustment structure is provided, which differs from the first embodiment in that a second connecting block 32 has a side wall along the hinge axis with an embedding groove 15, a torsion spring 4 is embedded in the embedding groove 15, and the torsion spring 4 is connected between the first connecting member 31 and the second connecting block 32.

[0054] The friction member 5 includes a gasket portion 19 and a friction portion 12.

[0055] The adjustment structure 3 is also provided with a protective cover 16. There are two protective covers 16. The two protective covers 16 are arranged one by one on the opposite sides of the first connecting member 31 along the hinge axis of the second connecting block 32. The protective cover 16 abutting against one side of the gasket portion 19 is provided with a fixing groove 17. The fixing groove 17 is located on the side of the protective cover 16 close to the second connecting block 32. A fixing portion 18 is fixed at the position of the second connecting block 32 corresponding to the fixing groove 17. The fixing portion 18 is adapted to the fixing groove 17. The fixing portion 18 is embedded in the fixing groove 17, so that when the first connecting member 31 and the second connecting block 32 rotate, the protective cover 16 swings with the second connecting block 32. The gasket portion 19 has a limiting portion 25, and the limiting portion 25 is embedded in the fixing portion 18, so that the gasket portion 19 and the second connecting block 32 swing synchronously.

[0056] The friction portion 12 has a positioning column 20, and there are four positioning columns 20. The four positioning columns 20 are evenly distributed in a quadrilateral shape. Each positioning column 20 protrudes and is fixed on the end surface of the friction portion 12 on the side away from the first connecting member 31. The four positioning columns 20 pass through the holes on the gasket portion 19 in a one-to-one manner. Four positioning holes 21 are also opened on the side of the protective cover 16 close to the friction member 5. The four positioning holes 21 are embedded in a one-to-one manner with the four positioning columns 20, so that the friction member 5 rotates with the protective cover 16, and is then fixed relative to the second connecting block 32.

[0057] The gasket portion 19 has a threaded hole 23, and the protective cover 16 has a clearance hole 24. One end of the locking member 11 passes through the clearance hole 24 and then passes through the adjustment structure 3 until the locking member 11 is threadedly connected to the threaded hole 23. The other end of the locking member 11 abuts against the end surface of the protective cover 16 on one side away from the first connecting member 31. The first connecting member 31 and the second connecting block 32 are hinged by the locking member 11. The locking member 11 can also be used to provide a hinge axis. Based on the relative fixation of the friction member 5 and the second connecting block 32, when the first connecting member 31 rotates, it forms a friction contact with the friction member 5, thereby generating friction resistance.
