Problems solved by technology
Since there is already a certain pre-tightening force on the elastic parts at the factory, when the customer adjusts the screw, the static friction between it and the adjustment shaft is large, which is not easy to adjust and easy to damage the adjustment seat

Embodiment Construction
[0022] refer to figure 1 , figure 2 and image 3 , the monitor bracket adjustment arm, including support base 1, suspension base 2, upper cantilever 3, lower cantilever 4 and preload spring 5; the two ends of upper cantilever 3 and lower cantilever 4 are respectively hinged on support base 1 and suspension base 2, composed The parallel four-bar linkage mechanism is provided with a pre-tightening force by the pre-tightening spring 5, and can maintain a load-bearing state to provide a constant pre-tightening force. This is also the advantage and feature of this type of structure.
[0023] One end of the preload spring 5 is connected to the suspension seat 2 and is located between the two hinge points, that is to say, between the hinge points of the upper boom 3 and the lower boom 4; the other end with the adjusting bolt is hinged on the In the upper cantilever 3 , the end of the upper cantilever 3 corresponds to the axial direction of the pretension spring 5 , and an operatio...

The invention relates to a display support adjusting arm which comprises a supporting base, a hanging base, an upper cantilever, a lower cantilever and a pre-tightening spring. The two ends of the upper cantilever and the two ends of the lower cantilever are hinged to the supporting base and the hanging base correspondingly to form a parallel four-connecting-rod mechanism, and pre-tightening forceis provided by the pre-tightening spring. Wherein one end of the pre-tightening spring is hinged to the hanging base and located at the position between two hinge points, the end portion, provided with an adjusting bolt, of the other end of the pre-tightening spring is hinged into the upper cantilever, the end portion of the upper cantilever corresponds to an operation hole formed in the axial direction of the pre-tightening spring, and the operation hole is located above the hinge point of the upper cantilever and the supporting base. According to the display support adjusting arm, one end of the pre-tightening spring is ingeniously positioned on the upper cantilever, so that the defect that hinge points and holes are densely formed in the supporting base is overcome, and the directionscan be kept relatively consistent during adjustment; and in addition, an end face bearing is arranged on the abutting portion of the adjusting bolt and the upper cantilever, adjustment is easier and more convenient, adjusted external force is not prone to being transmitted to other components of equipment, and the overall structure tends to be more reasonable.
Description
Technical field: [0001] The invention relates to an adjusting arm of a monitor support, in particular to a solution in which one end of an adjusting bolt of a pre-tightened spring band is positioned on an upper cantilever. Background technique: [0002] The adjustment bracket comes along with the development of liquid crystal displays. Compared with the fixed base of the display, it not only has the adjustment of up and down, left and right, but also can meet the needs of far and near stretching. It is flexible and easy to use, and is widely welcomed by the market. optimization. The adjustment principle of the bracket is still the method of four-bar linkage mechanism with pre-tightened spring, which is nothing more than strengthening the components in consideration of the difference in load-bearing. [0003] For example, the patent application number 201610724374.7 discloses an adjustment support mechanism for a display stand, including an adjustment base, an installation b...
