Description

The present invention relates to an adjustment structure for a support arm of a monitor.

LCD TVs and LCD monitors are becoming thinner and lighter and are used for public information display. Regardless of whether they are upright or wall-mounted, most of them are fixed by a support arm. The purpose of these support arms is to facilitate viewing and operation by adjusting the elevation angle, depression angle, and direction in addition to the purpose of installing the monitor.
The adjustable support arm used in conventional monitors is fixed to the joint structure with a screw, and when adjusting, loosen the screw to adjust the support arm to an appropriate height, and then tighten the screw again to fix it It has become. This type of “screw-type fixing” is troublesome because it is necessary to support the monitor with the other hand while loosening the screw with one hand so that the monitor does not fall suddenly due to weight when loosening the screw. Occurs. At the same time, it is difficult to fine-tune the height of a small range, and the fixing screws must be securely tightened.
Also, the improved adjustable arm that employs a hydraulic cylinder has the effect of supporting the hydraulic cylinder, making it easier to adjust than the “screw-type fixing” method. However, the method of supporting the hydraulic cylinder is “fixed position”, and at the same time, it is necessary to use screws. The screw wears out after being adjusted many times, and the tightening force decreases. Therefore, a problem arises in that it is checked whether the screw is tightened each time adjustment is performed.

The purpose of the present invention is to provide a monitor support arm adjustment structure that has a slide-type device between the monitor and the support arm, and is easy to install by adjusting the vertical height using this device. The task is to do.

The monitor support arm adjustment structure of the present invention has a slide-type device between the monitor and the support arm, which is used to adjust the vertical height. The support arm of the present invention includes a fixed unit, a slide unit, and a slide device. The fixed unit has a telescoping tank to which a support arm is attached. There are a pair of insertion connection tanks on both the left and right sides, and the slide unit can be fitted therein. The slide device is adapted to be coupled with a monitor.
When the user holds both sides of the monitor, it will just move the control bar, and the gear teeth will be released from the stopper restraint and will rotate freely. In this way, the slide device connected to the monitor and the gear fixing tank of the slide unit are engaged with each other, so that the height can be adjusted to an appropriate height quickly and accurately. At the same time, it is possible to finely adjust a small interval. When the control bar is released, it is fixed to the stopper unit again, and the monitor is supported stably. Therefore, the support arm of the present invention has a simple structure, light weight, and easy operation.

The support arm adjustment structure of the monitor of the present invention has a feature that it can be adjusted quickly and accurately to an appropriate position using a slide type mechanism, and fine adjustment at a small interval is also possible.
The monitor support arm adjustment structure of the present invention has a simple structure, light weight, and easy operation.

Please refer to FIG. 1 and FIG. The adjustment structure of the support arm of the monitor according to the present invention includes a fixed unit 1, a slide unit 2, and a slide device 3.

Furthermore, please refer to FIG. 3 and FIG. The fixing unit 1 has several fixing holes 11 in pairs at different heights of the main body, and has fitting tanks 12 at different heights, and a support arm 4 (see FIG. 6) is attached. It is like that. Moreover, there is a pair of insertion connection tanks 13 on both sides of the fixed unit 1, which is slightly wider than the slide unit 2, so that the slide unit 2 can be fitted therein. Both sides of the slide unit 2 are continuous concave and convex gear fixed tanks 21, and there are several spring pieces 22 projecting obliquely outward on the rear side of the slide unit 2. At the same time, there are fixing tenons 21 corresponding to the positions of the paired fixing holes 11 at the end portions of the spring pieces 22 so that the slide unit 2 and the fixing unit 1 are firmly fixed when they are coupled.

Please refer to FIG. 3 and FIG. One side of the slide device 3 is an assembly plate 31, which has several fixing holes 311 for fixing the monitor 5 (see FIG. 8). Further, on the other side, a control bar 33, a gear 34, and a stopper unit 35 are installed in the storage space of the outer case 32. Further, there are openings 321 on both sides of the outer case 32. The control bar 33 penetrates one side surface of the outer case 32. The intermediate support bar 331 is fixed so as to straddle the U-shaped tank 322 which is a pair of one side surface of the outer case 32. The handle 332 at one end of the control bar 33 is moved up and down by a receiving portion 333 interlocked with the end. The stopper unit 35 is located at the upper end of the receiving portion 333 of the control bar 33 and has stoppers 351 extending in parallel on both sides thereof. Further, the compression spring 36 is located between the stopper unit 35 and the outer case 32, and the stopper unit 35 is usually fixed by receiving the elasticity of the compression spring 36. The gear 34 is fitted in the wheel bar 37 and is installed on both sides of the stopper unit 35 as a pair. Each gear tooth portion 341 is slightly exposed from the opening 321 of the outer case 32 and is connected to the stopper 351 of the stopper unit 35 so as to engage with each other and exert an effect of firmly stopping.

Please refer to FIG. 5 and FIG. The above-mentioned slide unit 2 is fitted from the end of the fixed unit 1, and the spring piece 22 of the slide unit 2 is compressed due to the spatial restriction of the fixed unit 1 and contracts inward. When the slide unit 2 and the fixing unit 1 are completely coupled, the spring piece 22 enters the position of the fixing hole 11 of the fixing unit 1, and the fixing tenon 221 is pushed into the fixing hole 11 by the return force of the spring piece 22 and fixed. To do. The slide unit 2 and the fixed unit 1 are united with each other. The monitor 5 is previously attached to the assembly plate 31 (see FIG. 5) of the slide device 3.

In addition, please refer to FIGS. After the slide device 3 and the monitor 5 are connected, the control bar 33 extends from the slide device 3 to the side of the monitor 5. When the user holds both sides of the monitor 5, the user just holds the handle 332 (see FIG. 6). Further, the receiving portion 333 at the end moves the stopper unit 35 by the lever principle and pushes it upward to hit the compression spring 36 (see FIG. 8). At the same time, the gear 34 is released from the binding between the gear tooth portion 341 and the stopper 351 and rotates freely. In this way, the vertical height (see FIG. 9) is adjusted by the engagement of the slide device 3 connected to the monitor 5 and the gear fixing tank 21 of the slide unit 2. When the user releases the control bar 33, the stopper unit 35 is pushed back to the original position by the force of returning to the compression spring 36, and the stopper 351 and the gear tooth portion 341 of the gear 34 are engaged with each other again and stopped (see FIG. 7). The monitor 5 can be fixed at any height of the slide unit 2.

In this way, the support arm adjustment structure of the monitor of the present invention can be adjusted to an appropriate height quickly and accurately by operating the control bar, and furthermore, the monitor is safe for secure fixation. There is an effect that it can be used.
