Technical Field

[0001] This utility model belongs to the field of display peripheral accessories, and specifically relates to a support arm device, particularly a solution that allows the display to move left and right along the arm. Background Technology

[0002] Monitor stands are widely used across various industries, addressing the limitations of original monitor stands and enabling adjustments such as zoom, tilt, and swivel. Monitor stands are broadly categorized into two types: column stands and cantilever stands. Cantilever stands offer greater adjustment flexibility but have limited load-bearing capacity. Column stands are often used in multi-screen setups, providing strong load-bearing capacity but lacking flexibility and having a limited adjustment range.

[0003] How to improve the flexibility of adjustment becomes the subject of this invention. Summary of the Invention

[0004] The purpose of this invention is to design a support arm device that can be adjusted laterally.

[0006] The suspension assembly includes a rivet shaft, a rotating shaft, a retaining plate, and friction plates. The rivet shaft is vertically riveted to the rotating shaft, and the retaining plate is movably sleeved on the splined section of the rotating shaft. Friction plates are provided on both sides of the retaining plate, which are sleeved on the splined section and constrained by nuts to maintain synchronization with the rotating shaft. The rotating shaft and retaining plate are installed in the cavity of the sliding body. The retaining plate is constrained by the sliding body, allowing the rotating shaft and rivet shaft to swing and adjust, and has damping self-positioning.

[0007] The slide body has a cavity and upper and lower sliders. At the position of the upper and lower sliders, there are also slots for inserting the double ears of the card plate to keep the card plate synchronized with the slide body. The card plate is inserted into the horizontal groove of the horizontal arm body by means of the upper and lower sliders and can be slidably adjusted.

[0008] The slide body is divided into upper and lower modules and has a rotationally symmetrical structure.

[0009] The rotating shaft has several disc-shaped washers between the friction plate and the nut.

[0010] The crossarm body is made of cut profile material, with sealing plastic parts at both ends, and is fastened together by screws; the back of the crossarm body is fitted with an adapter for connecting to the column or cantilever.

[0030] Reference Figures 1 to 7 The support crossarm device includes a crossarm body 1 and a suspension assembly 2. The crossarm body 1 has an open cross groove 11 formed in the middle. The design width of the opening 12 allows the suspension assembly to be tilted. More specifically, the crossarm body 1 is made of cut profile and has sealing plastic parts 13 at both ends, which are locked together by screws 4. On the back of the crossarm body 11, there is an adapter seat 3 for connecting with a column or cantilever.

[0031] The suspension assembly 2 includes a slide body 21 and a mounting plate assembly 22 connected thereto. The slide body 21 fits into the transverse groove 11 of the cross arm body and can move within the transverse groove. The rivet shaft 221 in the mounting plate assembly 22 passes through the slide body 21 and is rotatably positioned at the outer end of the transverse groove opening 12 to secure the suspension plate 227 for locking the display.

[0032] The mounting plate assembly 22 includes a rivet shaft 221, a rotating shaft 222, a clamping plate 223, and friction plates 224. The rivet shaft 221 is vertically riveted to the rotating shaft 222, forming a rotating shaft perpendicular to both directions. The clamping plate 223 is movably sleeved on the splined section 2221 of the rotating shaft. Friction plates 224 are provided on both sides of the clamping plate 223. The friction plates 224 are sleeved on the splined section 2221, constrained by nuts 225 and kept synchronized with the rotating shaft 222. The friction force between the friction plates 224 and the clamping plate 223, i.e., the damping force required for self-positioning, can be adjusted by loosening or loosening the nuts 225 to accommodate displays of different weights. The rotating shaft 222 and the clamping plate 223 are installed in the cavity 211 of the slide body 21. The clamping plate 223 is constrained by the slide body 21, allowing the rotating shaft 222 and the rivet shaft 221 to swing and adjust, and providing damped self-positioning.

[0033] The slide body 21 has a cavity 211 and upper and lower sliders 212. A slot 213 is formed at the position of the upper and lower sliders 212 for inserting the double ears of the retaining plate 223, keeping the retaining plate 223 synchronized with the slide body 21. It is inserted into the transverse groove 11 of the cross arm body by means of the upper and lower sliders 212 and can be slidably adjusted. Furthermore, the slide body 21 has upper and lower molds and a rotationally symmetrical structure, reducing the number of molds and facilitating assembly.

[0034] In this example, representing a preferred design, both the slider 21 and the suspension assembly 2 are symmetrically designed. With the rivet shaft 221 as the axis of symmetry, friction plates 224, clamping plates 223, and nuts 225 are symmetrically arranged on both sides of the rotating shaft 222. Several disc-shaped washers 226 are also provided between the friction plates 224 and the nuts 225, enabling elastic pre-tightening and providing greater adjustment tolerance and easier adjustment. Furthermore, the rivet shaft 221 can rotatably position the suspension plate 227. Washers 228 are placed on both sides of the suspension plate 227, creating friction between the washers and the suspension plate, allowing the suspension plate 227 to rotate and adjust, satisfying the needs of adjusting the monitor's horizontal and vertical screen angles.

[0035] In addition to being used as a single horizontal arm body 1, this solution can also be spliced ​​together with multiple sections to expand into a foldable multi-screen bracket, as detailed below:

[0036] Reference Figure 8 The crossarm body 1 is assembled from multiple sections of truncated profiles. Adjacent sections are hinged together by hinges 14, allowing adjacent sections to be folded together to reduce the overall length of the crossarm body, facilitating storage, packaging, and transportation. At both ends of the assembly, sealing plastic parts 13 are provided and secured together by screws 4. The back of the middle section of the crossarm body 1 has a connecting seat 3 for connecting to a column or cantilever. This example shows a three-section assembly with suspension assemblies on the left and right sides of the crossarm body 1, and the middle section serving as the spacing and load-bearing foundation. A two-section design is also possible; in this case, crossarm bodies of unequal length can be used, with the longer section having a connecting seat 3 on its back, which can also achieve balanced load-bearing on both sides.

[0037] In this structure, the crossarm body 1 is preferably made of aluminum alloy profile. Different specifications and lengths can be cut according to product requirements, and the size of the monitor bracket can be flexibly adjusted to quickly produce finished products. The specifications of the matching sealing plastic parts remain unchanged, and the versatility is strong.
