Preferably, the mounting plate 1 is movably connected with the upper bracket 3, and the upper bracket 3 is movably connected with the lower bracket 4, so that the mounting height and angle of the display can be adjusted by adjusting the angle between the mounting plate 1 and the upper bracket 3 and/or the angle between the upper bracket 3 and the lower bracket 4. Specifically, the mounting plate 1 and the upper bracket 3, and the upper bracket 3 and the lower bracket 4 of the present embodiment are all selected to be in hinged connection.

Preferably, this embodiment is provided with hinge bracket 2 between mounting panel 1 and upper bracket 3, and both ends articulate mounting panel 1 and upper bracket 3 respectively around hinge bracket 2. The arrangement of the hinged frame 2 enables two rotating mechanisms to exist in a small area between the mounting plate 1 and the upper support 3, and the height and the angle of the display can be adjusted more conveniently and flexibly.

As is well known, in the market, the display, whether it is a television or a computer, has various sizes and different weights, and accordingly, the support force required to be provided by the display bracket is also different. If a display bracket is designed for each size of display, the working strength of a producer is too high, and a consumer needs to replace the display bracket matched with the display bracket when replacing the display with one size, so that the previous display bracket is lost with a high probability, and serious waste is caused. Therefore, in order to improve the universality of the monitor support, so that one monitor support can be used for supporting and fixing monitors with various sizes, the embodiment also discloses a supporting force adjusting mechanism 5 (the structure of which is shown in fig. 2, 3 and 4), which is arranged in the upper support 3, and the supporting force of the upper support 3 can be adjusted by the supporting force adjusting mechanism 5 to adapt to the size and the weight of the monitor, so that one monitor support can be suitable for monitors with various sizes and different weights.

Referring to fig. 4, the supporting and adjusting mechanism 5 includes a spring 51, a screw 52, a connecting member 53 and a rotating portion 54, the spring 51 and the screw 52 are disposed along the axial direction of the upper frame 3, the front end of the spring 51 is fixed on the inner wall of the front end of the upper frame 3, the rear end of the spring 51 is fixed with the connecting member 53, the connecting member 53 is movably sleeved on the screw 52, the screw 52 is disposed at the rear end of the spring 51, the front end of the screw 52 can be inserted into the spring 51 along the axial direction of the spring 51, the rear end of the screw 52 is provided with the rotating portion 54, so that the screw 52 is driven to rotate by the rotating portion 54, the connecting member 53 makes a linear motion along the axial direction of the screw 52, and the spring 51 is further stretched or compressed to change the spring force thereof, thereby adjusting the supporting force.

Preferably, the central axes of the screw 52, the connecting member 53 and the spring 51 are overlapped, so as to achieve the purpose of saving labor when the spring 51 is stretched or compressed to a certain extent. More specifically, the outer surface of the screw 52 of the present embodiment is provided with an external thread 521 spirally wound along the axial direction thereof, the connecting member 53 is selected as a nut, the inner wall thereof is provided with an internal thread (not shown) adapted to the external thread 521, the screw 52 is spirally sleeved with the nut, and when the rotating portion 54 drives the screw 52 to rotate, the nut linearly moves along the axial direction of the screw 52 to compress or extend the spring 51 according to the rotating direction of the screw 52, so as to change the spring force of the spring 51, and further achieve the purpose of changing the supporting force of the upper bracket 3.

Referring to fig. 3, a locking groove 31 is formed on an inner wall of a rear end of the upper bracket 3, a locking block 522 adapted to the locking groove 31 is formed at a rear end of the screw 52, the locking block 522 is locked in the locking groove 31, and a gap for allowing the screw 52 to rotate around a central axis thereof is formed at a joint of the locking block 522 and the locking groove 31. In this embodiment, through the clamping structure with the fixture block 522 and the clamping groove 31, the screw 52 can be fixed to prevent the screw 52 from deviating in the up-down direction and/or the left-right direction, and the screw 52 can only rotate along the central axis thereof, so as to ensure that the central axes of the screw 52 and the spring 31 are always overlapped, thereby achieving the purpose of saving labor, and preventing the screw 52 from being bent due to deviation in position, affecting the transmission precision of the nut of the screw 52, and even damaging the spring 51, the nut, the screw 52 and other components.

For the rotating portion 54 of the present embodiment, it can be configured as a knob 541, the knob 541 is disposed at the rear end of the upper bracket 3 and extends into the upper bracket 3 to be fixed at the rear end of the screw 52, the rotation 541 and the screw 52 rotate coaxially, so that screwing the knob 541 can drive the screw 52 to rotate synchronously, so that the nut moves linearly along the axial direction of the screw 52 to compress or stretch the spring 51, thereby changing the spring force of the spring 51, and further achieving the purpose of changing the supporting force of the upper bracket 3.

It should be noted that, if the upper bracket 3 is capable of providing a plurality of supporting forces, the selection of the spring 51 is important, and it has both sufficient deformability and sufficient rigidity to achieve the supporting and adjusting purposes. In the present embodiment, the spring 51 is selected as an extension spring, which is a coil spring that receives an axial tensile force, and as a spring, it has an excellent deformability, and when the extension spring does not receive a load, the coil of the extension spring is not closely spaced from the coil, and has a sufficiently strong rigidity, so that the extension spring selected in the present embodiment can satisfy both requirements of support and adjustment.

However, when the tension spring is not loaded, the coils are tightly spaced, and the rigidity is strong, so that a large force is required to elongate the tension spring, and if the screw 52 is directly driven to rotate by screwing the knob 541, the tension spring is very laborious to elongate, and the screw 52 may be broken by carelessness, which may even harm the safety of the user. Therefore, referring to fig. 2 and 4, the rotating portion 54 of the present embodiment further includes a labor-saving transmission mechanism disposed between the knob 541 and the screw 52.

Specifically, referring to fig. 4 and fig. 5, the labor-saving transmission mechanism of the present embodiment includes a worm wheel 542, a worm 543, and a rotating shaft 544, the worm wheel 542 is sleeved at the rear end of the screw 52, the worm wheel 542 is fixed relative to the screw 52, the worm 543 and the knob 541 are both sleeved on the rotating shaft 544, the worm 543, the knob 541, and the rotating shaft 544 are fixed relative to each other and can rotate coaxially, and the worm wheel 542 is engaged with the worm 543. The knob 541 is screwed to drive the rotating shaft 544 and the worm 543 to synchronously rotate, the worm wheel 542 is driven to rotate through the meshing transmission of the worm wheel 542 and the worm 543, the screw rod 52 is driven to synchronously rotate with the worm wheel 542, the nut stretches the extension spring in different degrees, the spring force of the extension spring is changed, and the purpose of changing the supporting force of the upper bracket 3 is achieved.

In this embodiment, a worm wheel 542-worm 543 labor-saving transmission mechanism is disposed between the knob 541 and the screw 52, when the knob 541 rotates one turn, the worm 543 correspondingly rotates one turn, and at this time, the number of teeth of the worm wheel 542 rotates is equal to the number of spiral lines on the surface of the worm 543, for example, there is only one spiral line on the surface of the worm 543, when the worm 543 rotates one turn, the worm wheel 542 only rotates one tooth, and accordingly, the screw 52 also only rotates one tooth of the worm wheel 542, so that when the knob 541 rotates one turn, only the screw 52 needs to rotate a small angle, and the corresponding force is also small, if the screw 52 rotates a designated number of turns, only the knob 541 needs to be rotated by a multiple of the number of teeth of the worm wheel 542 and the number of spiral lines of the worm 52, thereby achieving the purpose of saving labor. Moreover, the proportional relationship between the number of teeth of the worm wheel 542 and the number of spiral lines of the worm 52 can be set correspondingly according to the requirements of the display bracket during design and production, and all the display brackets are not required to be designed into the same type.

In practical application, the structure of the worm wheel 542-worm 543 is not necessarily adopted to achieve the purpose of saving labor, and any labor-saving transmission mechanism commonly used in the field can be adopted as required, so long as the purpose of saving labor is achieved.

It should be noted that, no matter the rotating portion 54 is directly designed as the knob 541, or the labor-saving transmission mechanism is designed between the knob 541 and the screw 52, at least a part of the structure of the knob 541 is located outside the upper frame 3, so as to facilitate the user to screw the knob 541. For example, when the knob 541 is directly connected to the screw 52, the knob 541 is provided outside the rear end of the upper bracket 3 and extends into the upper bracket 3 to be fixed to the rear end of the screw 52. Referring to fig. 2 and 5, when the labor-saving transmission mechanism is disposed between the knob 541 and the screw 52, the worm wheel 542 and the worm 543 are engaged with the rear end of the upper bracket 3, the rotating shaft 544 passes through the worm 543, and at least one end of the rotating shaft passes through the upper bracket 3, and the knob 541 is sleeved on the end of the rotating shaft 544 passing through the upper bracket 3.

Preferably, in both of the above connection modes, the knob 541 can be designed to be detachable. Because the knob 541 is arranged outside the upper bracket 3, and the knob 541 is often screwed by a user and is easy to damage, the knob 541 is designed to be a detachable structure, and after the knob 541 is damaged, the knob 541 with corresponding size only needs to be replaced, a new display bracket does not need to be bought, waste is avoided, and the rights and interests of consumers are guaranteed.

It is worth emphasizing that, the knob 541 is used as a part of the display bracket and is directly installed on the display bracket, when the supporting force needs to be adjusted, the knob 541 is directly screwed, without using an external tool, so that a consumer can adjust the supporting force of the display bracket according to the supporting force needed by the display, the operation is convenient, the practicability is strong, and the support is popular with the consumer.

The technical means disclosed by the scheme of the present invention is not limited to the technical means disclosed by the above embodiments, but also includes the technical scheme formed by the arbitrary combination of the above technical features. It should be noted that, for those skilled in the art, without departing from the principle of the present invention, several improvements and modifications can be made, and these improvements and modifications are also considered as the protection scope of the present invention.
