Description
Technical Field
[0001] The utility model relates to an adjustable desktop display bracket. Background Art
[0002] A monitor stand is a product that can fix a monitor, a notebook or a tablet computer, etc., and can help solve various technical problems encountered by people when operating a computer at home or in a commercial office. A desktop monitor stand refers to a monitor stand that can be placed on a table for use. Although the existing desktop monitor stand can adjust the position and angle of the monitor with the help of a rocker arm, and the number of rockers is generally two, which can have a larger adjustment range, it is impossible to adjust the height of the monitor, so the adjustment function is limited. If you want to adjust the height of the monitor, you must install a support tube on the base, and then install the rocker arm on the support tube, and finally adjust the height of the monitor by adjusting the fixed height of the rocker arm. However, the structural complexity of the stand is increased, and in order to fix the rocker arm, a knob screw or a fastening bolt needs to be set between the rocker arm and the support tube. Before adjustment, one person must hold the monitor first, and then another person loosens the knob screw or the fastening bolt, and then the rocker arm can be moved up and down to adjust the height of the monitor, and finally the knob screw or the fastening bolt is tightened after the adjustment is completed. Therefore, the operation steps are relatively cumbersome, and one person cannot complete it, and daily use is relatively inconvenient, which needs further improvement. Utility Model Content

Slot 37, then plug the power cord and signal line led out from the monitor into the U-shaped wire slot 37, and then reverse the operation in the same way to install the U-shaped wire slot 37 back to the bottom of the lower traction arm 32, so that the power cord and signal line are arranged and hidden on the lower traction arm 32; then the power cord and signal line are wrapped around the rear of the support arm 2 and the line cover 7 is removed, and then the power cord and signal line are plugged into the wiring cavity 21, and the upper parts of the power cord and signal line are respectively embedded in the corresponding notched grooves 71 at the top, and the lower parts of the power cord and signal line are respectively embedded in the corresponding notched grooves 71 at the bottom, so that the power cord and signal line are arranged and hidden on the support arm 2, and then the monitor can be used normally.
[0023] The display can be rotated in the horizontal direction with the help of the support arm 2 to change the orientation. The display can continue to rotate in the horizontal direction with the help of the adjustment arm 3 to superimpose the change of orientation and adjust the distance. The display can be swung left and right in the horizontal direction with the help of the U-shaped adapter 6 to change the orientation. The display can be swung up and down with the help of the U-shaped plate 4 to change the pitch angle. The display can be rotated in the vertical direction with the help of the U-shaped plate 4 to level. The above principles are all prior arts.
[0024] The height of the display can also be changed with the help of the adjustment arm 3. When adjusting, first hold the display with your hand and then move it vertically upward or downward, thereby changing the inclination angle of the reinforcement arm 34, the upper traction arm 31 and the lower traction arm 32; when the display moves upward, the angle between the reinforcement arm 34, the upper traction arm 31 and the lower traction arm 32 and the horizontal direction becomes larger, the position of the second connecting seat 39 rises, and the spring 33 is further stretched. After letting go, the rebound force of the spring 33 will be transmitted to the U-shaped adapter 6 through the connection relationship between the reinforcement arm 34, the upper traction arm 31 and the lower traction arm 32 and the first connecting seat 38 and the second connecting seat 39, and then connected with the U-shaped adapter 6, the U-shaped plate 4, the display The weight of the device fixing plate 5 and the display is automatically balanced, so that the display maintains its height; on the contrary, when the display moves downward, the angle between the reinforcing arm 34, the upper traction arm 31 and the lower traction arm 32 and the horizontal direction becomes smaller, the position of the second connecting seat 39 is lowered, and the stretching amount of the spring 33 is reduced. After letting go, the rebound force of the spring 33 will be transmitted to the U-shaped adapter 6 through the connection relationship between the reinforcing arm 34, the upper traction arm 31 and the lower traction arm 32 and the first connecting seat 38 and the second connecting seat 39, and then automatically reach a balance with the weight of the U-shaped adapter 6, the U-shaped plate 4, the display fixing plate 5 and the display, so that the display maintains its height.
[0025] A wire 8 is connected to each USB female connector 13, and each wire 8 is arranged in the seat shell 11. The ends of each wire 8 are led outward after being connected in parallel and connected to the mains, so that each USB female connector 13 can be charged. When the user wants to charge some electronic devices, the USB male connector on the charging cable used to connect the electronic devices can be inserted into the interface of the USB female connector 13 through the groove 111 for charging, eliminating the need to use a charging plug.
[0026] The utility model can change the height of the display with the help of the adjustment arm 3, thereby expanding the adjustment function, and there is no need to install a support tube and a knob screw or a fastening bolt on the base 1, thereby simplifying the structure and simplifying the adjustment steps for ease of use. In addition, it can be completed quickly and easily by one person.
[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
