Description

Technical Field

[0001] The present technical solution relates to the technical field of brackets, and in particular to an elastic compensation structure of a display bracket. Background Art

[0002] A monitor stand is a support device installed on a desktop to support and fix the monitor. The height, tilt angle, and rotation direction of the monitor can be adjusted according to personal preferences and work needs.

[0003] For example, Chinese patent CN102620125A discloses a monitor stand and a swing arm thereof, wherein the monitor stand comprises a base assembly, a first rotating arm, a swing arm, and a monitor mounting plate, and the swing arm comprises an upper shell, a lower shell, a small Y-shaped part, a spring part, a spring joint, a small U-shaped part, and a fixing bolt; the spring joint is fixed to the upper shell and is placed between the upper shell and the lower shell, the fixing bolt passes through the small U-shaped part and the spring part and is connected to the spring joint, the small U-shaped part is fixed between the upper shell and the small Y-shaped part, and the elongation and compression of the spring are adjusted by the fixing bolt, thereby adjusting the magnitude of the force supporting the monitor, so that it can support displays of different weights.

[0004] In the above-mentioned display stand, the upper shell and the lower shell in the existing display stand are connected by a spring member. When the display is adjusted downward, the pulling force on the spring member increases, causing the spring member to continuously stretch and maintain a large elastic force, resulting in unbalanced adjustment of the display, which needs to be improved. Summary of the invention

[0005] In order to improve the problem of unbalanced use of the monitor when it is adjusted downward, the present technical solution provides an elastic compensation structure for a monitor stand.

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

[0007] A display stand elastic compensation structure comprises an adjustment rod, a first connecting part and a second connecting part, the first connecting part and the second connecting part are hinged to the opposite ends of the adjustment rod in a one-to-one correspondence, the adjustment rod comprises an upper connecting rod and a lower connecting rod, the lower connecting rod is hinged to the first connecting part to form a hinge point one, an installation cavity is spliced ​​between the upper connecting rod and the lower connecting rod, a connecting rod structure is arranged in the installation cavity, the connecting rod structure comprises a connecting rod one and a connecting rod two, the connecting rod two is hinged between the connecting rod one and the lower connecting rod to form two hinge points two, the connecting rod one is hinged to the first connecting part to form a hinge point three, an elastic member is also installed in the installation cavity, one end of the elastic member is connected to an end of the connecting rod one away from the hinge point three.

[0008] Through the above technical solution, when the elastic compensation structure of the monitor stand is used normally, one end of the adjustment rod provided with the second connection part is fixed on the desktop, and the hinge relationship between the adjustment rod and the second connection part is used as a fulcrum to realize the swing adjustment of lifting or lowering. Based on the hinge connection between the first connection part and the adjustment rod, the elastic force of the elastic member acts on the first connection part and the second connection part at the same time. When the adjustment rod is lifted, the elastic member pulls the first connection part so that the adjustment rod is maintained at the height and angle of the lifting, and limits the gravity sagging of the adjustment rod, thereby improving the adjustment stability. The four nodes of the quadrilateral are formed by the hinge point one, the two hinge points two and the hinge point three. Based on the connection of one end of the elastic member to the connecting rod one, when the adjustment rod is adjusted to drop, the quadrilateral structure will be deformed accordingly, the connecting rod structure and the elastic member swing synchronously according to the movement, and the first connection part and the lower connecting rod rotate around the hinge, so that the hinge structures at the four nodes cooperate to compensate for the deformation of the elastic member, ensuring that it tends to be balanced and stable after adjustment, thereby changing the angle of the elastic member and the adjustment rod, and realizing that the adjustment rod after swinging up and down is maintained at any height for positioning support, thereby making the balance of the monitor better during the adjustment process.

[0009] Preferably, the hinge point one, the two hinge points two and the hinge point three cooperate with each other to form four fulcrums of a quadrilateral.

[0010] Through the above technical solution, four nodes of a quadrilateral are formed by hinge point one, two hinge points two and hinge point three, and the unstable characteristics of the quadrilateral structure are utilized to realize the adjustment of the elastic part following the swing of the adjustment rod, thereby improving the balance of the adjustment.

[0011] Preferably, one end of the lower connecting rod away from the hinge point one is hinged to the second connecting part to form a hinge point four, and the upper connecting rod is hinged between the first connecting part and the second connecting part to form two hinge points five, and the upper connecting rod and the lower connecting rod slide relative to each other.

[0012] Through the above technical solution, the upper connecting rod and the lower connecting rod are spliced ​​into an adjusting rod, so that when the adjusting rod swings, the upper connecting rod and the lower connecting rod respectively rotate around the hinge points at both ends of each other, so that the upper connecting rod and the lower connecting rod slide relative to each other to adjust the height and angle of the adjusting rod, adapting to more adjustment angles and height changes.

[0013] Preferably, the hinge point one, the two hinge points five and the hinge point four cooperate with each other to form four fulcrums of a quadrilateral.

[0014] Through the above technical solution, four nodes of another quadrilateral are formed by hinge point one, hinge point four and two hinge points five, and the unstable characteristics of the quadrilateral structure are used to realize the variable adjustment between the upper connecting rod and the lower connecting rod, thereby further improving the balance of the adjustment.

[0015] Preferably, an adjusting member is provided in the installation cavity, the adjusting member comprises a connecting member and a fixing rod, the second connecting portion is provided with a clearance hole, and the fixing rod is connected to the connecting member after passing through the clearance hole;

[0016] One end of the elastic member away from the connecting rod is arranged on the connecting member, and the adjusting member is used to adjust the deformation amount of the elastic member.

[0017] Through the above technical solution, after one end of the fixed rod in the adjusting member is passed through the yield hole of the second connecting part, the fixed rod is connected to the connecting member, and the two ends of the elastic member are respectively connected to the connecting member and the connecting rod one. When the connecting rod one moves, the elastic member is stretched, and the elastic force of the elastic member also acts on the connecting rod one. The deformation of the elastic member is changed by operating the adjusting member. As the degree of stretching changes, the magnitude of the pulling force acting on the connecting rod one changes, thereby improving stability and adjustability.

[0018] Preferably, the connecting member is provided with a limit block, the limit block is slidably connected to the connecting member, and the connecting member has a limit portion, the limit portion is used to limit the limit block from sliding away;

[0019] The outer wall of the limit block is provided with a thread groove along the circumferential direction, the elastic member is embedded in the thread groove, the limit block has a supporting portion, the supporting portion is arranged at one end of the limit block along the sliding direction, and the supporting portion is used for the elastic member to abut.

[0020] Through the above technical scheme, the thread groove of the limit block is adapted to the elastic member, so that the elastic member is fixed between the connecting rod and the limit block after being embedded in the thread groove. Based on the sliding connection between the limit block and the connecting member, when the elastic member is stretched, the limit block abuts against the limiting part of the connecting member, limiting the further movement of the limit block and ensuring the stretching stability. When the elastic member is compressed, the elastic member abuts against the abutting part of the limit block, and the limit block slides to provide necessary clearance adjustment, thereby improving the adjustability. By rotating the fixing rod to change the different connection positions of the connecting member, the limit block moves to adjust the deformation amount of the elastic member. When the connecting member is close to the second vehicle connecting part, the limit block tightens the elastic member more, resulting in an increase in the elastic force generated by the elastic member. Conversely, when the connecting member is close to the first connecting part, the tension of the elastic member is reduced, and the elastic force is reduced, thereby achieving further adjustment of the stretching amount of the elastic member.

[0021] Preferably, the second connecting portion has an arc guide surface 1, the give way hole is opened on the arc guide surface 1, the fixing rod has a bolt head, the second connecting portion is provided with an adjusting slider, the adjusting slider is abutted between the bolt head and the arc guide surface 1, and the end face of the adjusting slider close to the arc guide surface 1 has an arc guide surface 2, and the arc guide surface 2 and the arc guide surface 1 form an arc guide.

[0022] Through the above technical solution, when the fixed rod swings up and down, the elastic member has a certain degree of swing offset, so that the adjusting member needs to be adjusted synchronously with the elastic member. By adding an adjusting slider, the arc guide surface 2 of the adjusting slider is in contact with the arc guide surface 1 of the second connecting part, and the bolt head of the fixed rod rests on the end face of the adjusting slider away from the arc guide surface 2, maintaining stable contact and smooth sliding, thereby effectively absorbing and transmitting the swing offset of the adjusting member.

[0023] Preferably, the adjusting slide block has a positioning groove, and the positioning groove is used for the fixing rod to be embedded.

[0024] Through the above technical solution, one end of the fixing rod with the bolt head is embedded in the positioning groove, ensuring that the adjusting slider and the fixing rod will not be separated when they swing synchronously, thereby improving stability.

[0025] Compared with the prior art, the technical solution has the following outstanding and beneficial technical effects:

[0026] 1. The technical solution is provided with a connecting rod structure in the installation cavity, the lower connecting rod is hinged with the first connecting part to form a hinge point 1, the connecting rod 2 is hinged between the connecting rod 1 and the lower connecting rod to form two hinge points 2, the connecting rod 1 is hinged to the first connecting part to form a hinge point 3, and the hinge point 1, the two hinge points 2 and the hinge point 3 form four nodes of a quadrilateral. The quadrilateral structure is deformed synchronously with the adjustment of the adjustment rod, and the deformation of the elastic member is compensated to ensure that it tends to be balanced and stable after adjustment, thereby improving the balance;

[0027] 2. In the technical solution, the end of the lower connecting rod away from the hinge point one is hinged to the second connecting part to form a hinge point four, and the upper connecting rod is hinged between the first connecting part and the second connecting part to form two hinge points five.

DETAILED DESCRIPTION

[0033] The specific implementation of the technical solution is further described in detail below with reference to the accompanying drawings.

[0034] Example:

[0035] See also Figure 1 , an elastic compensation structure of a display stand, comprising an adjusting rod 1, a first connecting part 2 and a second connecting part 3, the first connecting part 2 and the second connecting part 3 are respectively located at opposite ends of the adjusting rod 1 in a one-to-one correspondence, the first connecting part 2 is hinged to the upper end of the adjusting rod 1, the second connecting part 3 is hinged to the lower end of the adjusting rod 1, the adjusting rod 1 comprises an upper connecting rod 11 and a lower connecting rod 12, the upper connecting rod 11 is located above the lower connecting rod 12, the first connecting part 2 is specifically hinged in a manner that one end of the upper connecting rod 11 is hinged to the first connecting part 2, a hinge point 5 13 is formed at the hinge, and one end of the lower connecting rod 12 is hinged to the first connecting part 2 to form a hinge point 14, The specific hinged mode of the second connecting part 3 adopts that one end of the upper connecting rod 11 away from the first connecting part 2 is hinged to the second connecting part 3, and another hinge point five 13 is formed at the hinge, so that there are two hinge points five 13, and the other end of the lower connecting rod 12 is hinged to the second connecting part 3 to form a hinge point four 10, and the hinge axes of the above hinge points are parallel to each other. When the adjusting rod 1 is rotated, the upper connecting rod 11 and the lower connecting rod 12 both rotate around the hinge axis. Since the hinge point one 4, the hinge point four 10 and the two hinge points five 13 cooperate to form four nodes of a quadrilateral, the upper connecting rod 11 and the lower connecting rod 12 slide relative to each other, thereby realizing the height and angle adjustment of the adjusting rod 1.

[0036] See also Figure 2 and Figure 3The adjusting rod 1 has an installation cavity 5, which is formed by splicing at the opening between the upper connecting rod 11 and the lower connecting rod 12. A connecting rod structure 6 is installed in the installation cavity 5, and the connecting rod structure 6 includes a connecting rod 1 61 and a connecting rod 2 62. One end of the connecting rod 1 61 is hinged to the first connecting part 2, and a hinge point 3 8 is formed between the connecting rod 1 61 and the first connecting part 2. The connecting rod 2 62 includes two connecting rods 62, which are located on opposite sides of the connecting rod 1 61 in a one-to-one correspondence. One end of the connecting rod 2 62 is hinged to the middle part of the connecting rod 1 61, and the other end of the connecting rod 2 62 is hinged to the lower connecting rod 12. Two hinge points 2 7 are formed between the connecting rod 2 62 relative to the connecting rod 1 61 and the lower connecting rod 12, and the hinge axes of the above hinge points are parallel to each other.

[0037] An elastic member 9 is also installed in the installation cavity 5. The elastic member 9 can be a tension spring. One end of the elastic member 9 is connected to the end of the connecting rod 61 away from the hinge point 3 8. The specific connection method is that a through hole is opened in the connecting rod 61, and one end of the elastic member 9 has a hook embedded in the through hole. An adjusting member 14 is also provided in the installation cavity 5. The adjusting member 14 is located on the side of the elastic member 9 close to the second connecting portion 3. The other end of the elastic member 9 is connected to the adjusting member 14. The elastic member 9 stretches or contracts synchronously with the swing of the adjusting rod 1. In order to avoid the elastic member 9 from being insufficiently tightened or over-tightened, the hinge point 3 8, the two hinge points 2 7 and the hinge point 1 4 are matched to form four nodes of a smaller quadrilateral, so that the connecting rod structure 6 rotates along the hinge axis to match the elastic member 9, thereby compensating for the deformation of the elastic member 9, ensuring that the elastic member 9 can tend to be balanced and stable after adjustment, thereby improving stability.

[0038] See also Figure 2 and Figure 4 The adjusting member 14 is used to adjust the deformation of the elastic member 9. The adjusting member 14 includes a connecting member 141 and a fixing rod 142. The connecting member 141 is provided with a limit block 23. The limit block 23 has a thread groove 17. The thread groove 17 is opened along the circumferential direction of the outer wall of the limit block 23. The thread groove 17 is adapted to the shape and specification of the elastic member 9, so that one end of the elastic member 9 is embedded along the thread groove 17, so that the elastic member 9 is fixed on the limit block 23. The limit block 23 is sleeved on the connecting member 141, and the limit block 23 is slidably connected relative to the connecting member 141. Alternatively, a connecting hole can be opened in the connecting member 141, and the elastic member 9 is hooked in the connecting hole and the through hole respectively by hooks at both ends, so that the two ends of the elastic member 9 are fixed to the connecting member 141 and the connecting rod 61 one by one.

[0039] The connecting member 141 has a limiting portion 16, which is located at one end of the connecting member 141 away from the second connecting portion 3. The limiting portion 16 is used for the limiting block 23 to abut against, so as to limit the sliding of the limiting block 23 when the elastic force of the elastic member 9 acts on the connecting member 141. The limiting block 23 has an abutting portion 18, which is arranged at one end of the limiting block 23 away from the limiting portion 16 along the sliding direction. The abutting portion 18 is used for the elastic member 9 to abut against, and the shape of the abutting portion 18 abuts against the inner wall of the mounting cavity 5 to limit rotation.

[0040] The second connecting part 3 is provided with a clearance hole 15, and the fixing rod 142 enters the installation cavity 5 after passing through the clearance hole 15. One end of the fixing rod 142 shown in this embodiment has a threaded structure, which is threadedly connected to the connecting member 141 through the threaded structure. The other end of the fixing rod 142 has a bolt head 20, and the bolt head 20 is against the side wall of the corresponding clearance hole 15 of the second connecting part 3. In this embodiment, the connecting member 141 has a hexagonal structure. By rotating the fixing rod 142, the connecting member 141 changes the position of the threaded connection, thereby adjusting different clearance spaces for the elastic member 9.

[0041] The second connecting part 3 has an arc guide surface 19, and the giving hole 15 is opened on the arc guide surface 19. The arc guide surface 19 is an arc surface with a certain curvature. The second connecting part 3 is also provided with an adjusting slider 21. The adjusting slider 21 has an arc guide surface 22. The arc guide surface 22 is an arc surface with a certain curvature, and the arc surface direction is the same as that of the arc guide surface 19, so that the adjusting slider 21 contacts the arc guide surface 19 and abuts on the second connecting part 3 through the arc guide surface 22, and the other side end surface of the adjusting slider 21 away from the arc guide surface 22 is used for the bolt head 20 to abut. The arc guide surface 22 is guided along the arc guide surface 19 to make the adjusting slider 21 swing. When the adjusting rod 1 is adjusted, it will drive the elastic member 9 to produce a swing deviation to a certain extent. Based on the connection between the elastic member 9 and the adjusting member 14, the adjusting member 14 realizes follow-up swinging through the adjusting slider 21 to avoid mutual conflict with the second connecting part 3.

[0042] The specific working process of this program is as follows:

[0043] The technical solution is to hinge the first connection part 2 with the adjustment rod 1, and the elastic force of the elastic member 9 acts on the first connection part 2 and the second connection part 3 at the same time. When the adjustment rod 1 is lifted, the elastic member 9 pulls the first connection part 2 to keep the adjustment rod 1 at the lifted height and angle, and limits the gravity sagging of the adjustment rod 1, thereby improving the adjustment stability. The four nodes of the quadrilateral are formed by the hinge point 1 4, the two hinge points 2 7 and the hinge point 3 8. Based on the fact that one end of the elastic member 9 is connected to the connecting rod 1 61, when the adjustment rod 1 is adjusted to drop, the quadrilateral structure will be deformed accordingly, and the connecting rod structure 6 and the elastic member 9 will swing synchronously according to the movement, and the first connection part 2 and the lower connecting rod 12 will rotate around the hinge, so that the hinge structures at the four nodes cooperate to compensate for the deformation of the elastic member 9, ensuring that it tends to be balanced and stable after adjustment, thereby changing the angle between the elastic member 9 and the adjustment rod 1, and realizing that the adjustment rod 1 after swinging up and down is kept at any height for positioning and support, thereby making the display better balanced during the adjustment process.
