Description

Technical Field

[0001] This utility model relates to the field of desktop monitor stand technology, specifically a desktop monitor stand using an adjustable tension spring. Background Technology

[0002] Desktop monitor stands are a common device. Modern desktop monitor stands need to have 360° rotation and height adjustment functions. When adjusting the height, a height adjustment arm is used. The current structure installs a gas spring in the height adjustment arm. However, gas springs are prone to leakage and failure after prolonged use. The replacement cost is relatively high, and users cannot replace them themselves. Moreover, the force of the gas spring cannot be adjusted, which leads to a poor user experience. Therefore, a more reliable desktop monitor stand is needed to solve the above problems. Utility Model Content

[0003] This invention provides a desktop monitor stand with an adjustable tension spring, which can solve the problem of easy failure of gas springs in existing desktop monitor stands.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a desktop monitor stand with an adjustable tension spring, comprising a mounting base and at least one rotating arm connected to the mounting base. The upper end of the rotating arm is connected to an upper and lower adjustable arm assembly via a rotating connecting seat. A bracket connecting seat is mounted on the upper end of the upper and lower adjustable arm assembly. A monitor connecting plate is mounted on the front side of the bracket connecting seat. The upper and lower adjustable arm assembly includes a lower arm and an upper arm. The lower arm, upper arm, bracket connecting seat, and rotating connecting seat are rotatably connected to form a deformable structure. A tension spring is installed inside the upper and lower adjustable arm assembly. The first end of the tension spring is connected to the bracket connecting seat via a connecting pin. A connecting nut is installed inside the second end of the tension spring. A screw is axially inserted through the connecting nut. The screw extends axially to the end of the upper and lower adjustable arm assembly connected to the rotating connecting seat. The tension spring, connecting nut, and screw form an adjustable elastic structure, which is reliable and can meet the requirements of long-term use of the upper and lower adjustable arm assembly.

[0005] Preferably, the connecting nut is conical, and the diameter of the second end of the tension spring gradually decreases, which can satisfy the connection of the connecting nut and also makes it easier for the position of the tension spring and the connecting nut to not deform.

[0006] Preferably, a V-shaped connecting piece is installed at one end of the upper arm near the rotating connecting seat. The screw passes through the V-shaped connecting piece, and the end of the screw is limited and matched with the inner side of the V-shaped connecting piece. The V-shaped connecting piece can protect the tail of the screw and prevent it from being exposed. The V-shaped connecting piece can also improve the strength of the upper arm.

[0007] Preferably, the first end of the tension spring is provided with a hook-shaped connecting part, which is connected to the connecting pin. The hook-shaped connecting part is firmly connected to the connecting pin and can also bypass the pin between the lower arm, the upper arm and the bracket connecting seat without interference.

A base is provided at the lower end of the connecting seat body. A damping plate is sandwiched between the base and the sleeve. A screw is provided through the base from bottom to top. The upper end of the screw is connected to a connecting piece inside the connecting seat body. By rotating the screw, the resistance of the sleeve rotating around the connecting seat body can be adjusted, which facilitates the adjustment of the rotation of the upper and lower adjusting arm assemblies.

[0009] Preferably, the lower side of the rotating arm and the lower arm is equipped with a cable storage section, which is convenient for organizing and storing various connection cables of the display during use.

[0010] Preferably, two rotating arms are mounted side by side on the upper side of the mounting base, which can be used to mount two displays, thus expanding the functionality of the bracket.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] like Figure 1-4 As shown, in this embodiment, to address the problem of easy failure of gas springs in existing desktop monitor stands, a desktop monitor stand using an adjustable tension spring is provided. The stand includes a mounting base 1 and at least one rotating arm 2 connected to the mounting base 1. The upper end of the rotating arm 2 is connected to an upper / lower adjustable arm assembly 3 via a rotating connecting seat 6. A bracket connecting seat 4 is mounted on the upper end of the upper / lower adjustable arm assembly 3. A monitor connecting plate 5 is mounted on the front side of the bracket connecting seat 4. The upper / lower adjustable arm assembly 3 includes a lower arm 52 and an upper arm 51. The lower arm 52, upper arm 51, and bracket connecting seat... The upper and lower adjusting arm assembly 3 is rotatably connected to the rotating connecting seat 6 to form a deformable structure. A tension spring 8 is installed inside the upper and lower adjusting arm assembly 3. The first end of the tension spring 8 is connected to the bracket connecting seat 4 through the connecting pin 53. A connecting nut 9 is installed inside the second end of the tension spring 8. A screw 7 is axially passed through the connecting nut 9. The screw 7 extends axially to the end of the upper and lower adjusting arm assembly 3 connected to the rotating connecting seat 6. The tension spring 8, the connecting nut 9 and the screw 7 form an adjustable elastic structure. The structure is reliable and can meet the long-term use requirements of the upper and lower adjusting arm assembly 3.

[0021] Specifically, the mounting base 1 can be fixed to the edge of the desktop, the rotating arm 2 can rotate around the mounting base 1, and the up-down adjustment arm assembly 3 can also rotate around the rotating arm 2, thereby realizing a wide range of horizontal adjustment of the monitor connection plate 5. The up-down adjustment arm assembly 3 can realize the up-down movement of the monitor connection plate 5. The lower arm 52, upper arm 51, bracket connection base 4 and rotating connection base 6 on the up-down adjustment arm assembly 3 form a parallelogram, which can change shape. When the monitor connection plate 5 moves downward, the tension spring 8 is stretched, generating resistance.

[0022] The position of the connecting nut 9 can be adjusted axially by rotating the screw 7, thereby adjusting the starting position of the tension spring 8 and thus adjusting the elastic resistance.

[0023] In this embodiment, the connecting nut 9 is conical, and the diameter of the second end of the tension spring 8 gradually decreases, which can satisfy the connection of the connecting nut 9 and also makes it easier for the connection position of the tension spring 8 and the connecting nut 9 to not deform. The connecting nut 9 and the tension spring 8 can be connected by welding, which is relatively firm.

[0024] In this embodiment, a V-shaped connecting piece 54 is installed at one end of the upper arm 51 near the rotating connecting seat 6. The screw 7 passes through the V-shaped connecting piece 54, and the end of the screw 7 is limited and matched with the inner side of the V-shaped connecting piece 54. The V-shaped connecting piece 54 can protect the tail of the screw 7 and prevent it from being exposed. The V-shaped connecting piece 54 can also improve the strength of the upper arm 51.

[0025] In this embodiment, the first end of the tension spring 8 is provided with a hook-shaped connecting part 10, which is connected to the connecting pin 53. The hook-shaped connecting part 10 is firmly connected to the connecting pin 53, and can also bypass the pin between the lower arm 52, the upper arm 51 and the bracket connecting seat 4 without interference.

[0026] In this embodiment, the rotating connector 6 includes a connector body 61 and a sleeve 66 fitted around the outside of the connector body 61. The sleeve 66 is connected to the rotating arm 2. A base 65 is provided at the lower end of the connector body 61. A damping plate 62 is sandwiched between the base 65 and the sleeve 66. A screw 64 passes through the base 65 from bottom to top. The upper end of the screw 64 is connected to a connecting piece 63 inside the connector body 61. By rotating the screw 64, the resistance of the sleeve 66 rotating around the connector body 61 can be adjusted, facilitating the adjustment of the rotation of the upper and lower adjusting arm assembly 3. At the same time, a cable storage part 11 is installed on the lower side of the rotating arm 2 and the lower arm 52, which is beneficial for organizing and storing various connecting cables of the display during use.

[0027] In this embodiment, as Figure 4 The mounting base has two rotating arms mounted side by side on its upper side, which can be used to mount two monitors, thus expanding the functionality of the bracket.

[0028] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0029] Furthermore, in this utility model, the use of terms such as "first," "second," etc., is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly and specifically defined.

[0030] In this utility model, unless otherwise explicitly specified and limited, the terms "connection," "fixing," etc., should be interpreted broadly. For example, "fixing" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0031] Furthermore, the technical solutions of the various embodiments of this utility model can be combined with each other, but only if they are based on the ability of those skilled in the art to implement them.
