Furthermore, the terms first, second, and the like, herein, are used solely for distinguishing between components and should not be limited by such terms, nor should they necessarily be used to indicate any such order of components or method of manufacture.

Referring to fig. 1, the display screen bracket includes a base 1, a support rod 2, a connecting rod 3 and a handle 4; the base 1 is usually supported on the ground to play a role in supporting the whole device, and pulleys can be arranged at the bottom of the base to realize the movement of the whole device; the support rod 2 is mounted on the base 1, preferably the support rod 2 extends upwards perpendicular to the base 1; the connecting rod 3 is used for fixing the display screen; the connecting rod 3 and the handle 4 are arranged on the supporting rod 2, the connecting rod 3 and the handle 4 are staggered in the circumferential direction of the supporting rod 2, and the connecting rod 3 and the handle 4 are relatively fixed, so that the connecting rod 3 can synchronously lift and/or rotate along with the handle 4. The circumferential offset means that the connecting rod 3 and the handle 4 should be located at a certain distance in the circumferential direction of the strut 2 (the handle is not located right above or right below the connecting rod), for example, as shown in fig. 1, the connecting rod 3 and the handle 4 are located at a half circumference in the circumferential direction of the strut 2 (the connecting rod is connected to the front of the strut and the handle 4 is connected to the back of the connecting rod 3), that is, the connecting rod 3 and the handle 4 are located at 180 ° from each other at two positions on the circumferential side of the strut 2, but this is only a specific implementation, or the connecting rod 3 and the handle 4 are located at 90 ° from each other at two positions on the circumferential side of the strut 2 (for example, as shown in fig. 11). The handle 4 may be located at any position on the side of the strut 2, as long as it is offset in the circumferential direction of the strut. In particular, in some embodiments, the connecting rod 3 and the handle 4 are disposed at an angle of 90 to 180 degrees in the circumferential direction of the strut 2. Because the handle and the connecting rod are arranged in a staggered manner, a user can operate the handle very conveniently, and because the handle and the connecting rod are relatively fixed, the user can synchronously control the lifting or the rotation of the connecting rod when operating the handle, and then control the display screen fixed on the connecting rod.

Referring to fig. 1, 2 and 3, the connecting rod 3 is mounted on the upper part of the strut 2, and in some embodiments the strut 2 is provided with a sliding rail extending axially along it, which may be provided on the outer surface of the strut or inside the strut, in which sliding rail a slider 5 is fitted, along which the slider 5 is movable, for example up and down in the axial direction of the strut; the handle 4 and/or the connecting rod 3 are connected to a slider 5. The sliding block 5 may be an independent fitting, or may be integrally formed with the connecting rod 3 or the handle 4.

In some embodiments, the slider 5 is a separate fitting, and the connecting rod 3 and the handle 4 are fixedly connected to the slider 5, for example, respectively fixed to opposite sides of the slider 5. Referring to fig. 1 and 4, the strut 2 is provided with a first chute 21 and a second chute 22 extending along the axial direction thereof, and the first chute 21 and the second chute 22 are staggered in the circumferential direction of the strut 2; the sliding rail is arranged in the supporting rod and is communicated with the first sliding groove 21 and the second sliding groove 22; the first runner 21 and the second runner 22 in the illustrated embodiment are the same length but differ in height on the strut 2. The connecting rod 3 passes through the first chute 21 to be fixed on the sliding block 5, the handle 4 passes through the second chute 22 to be fixed on the sliding block 5, the connecting rod 3 and the handle 4 are coaxially arranged, and the connecting rod 3 and the handle 4 are inclined relative to the supporting rod 2, so that a user can conveniently act on the handle 4 along the transverse direction or the longitudinal direction of the supporting rod 2. Therefore, when the display screen is required to be lifted, the user can directly operate the handle 4 to drive the sliding block to move up and down along the sliding rail (namely, move along the axial direction of the supporting rod), and then the connecting rod fixed on the sliding block also moves up and down synchronously, so that the display screen fixed on the connecting rod can be lifted. As shown in fig. 4, the handle is in a low position; as shown in fig. 5, the handle is raised to the raised position.

Further, in some embodiments, a damping connection is provided between the slider 5 and the sliding rail, and an elastic member (e.g. a torsion spring) is further provided in the strut, where the elastic member is connected to the slider 5 and the strut 2, respectively, and the elastic member is used to provide an upward elastic force for the slider 5. The friction resistance F1 between the sliding block and the sliding rail, the total force obtained by subtracting the elastic force born by the sliding block from the sum of the weight of the display screen, the weight of the sliding block, the weight of the connecting rod and the weight of the handle is F2, so that a user can adjust the height of the display screen only by making the force larger than (F1-F2), the user can easily adjust the height of the display screen with smaller force, and the stepless adjustment of the height of the display screen can be realized. In other embodiments, a plurality of elastic protruding blocks are arranged in the sliding rail at intervals along the extending direction, the elastic protruding blocks are used for supporting the sliding block 5, and when the sliding block 5 moves along the sliding rail, the sliding block 5 needs to sequentially press and pass through each elastic protruding block, and the embodiment can enable the display screen to achieve gear adjustment when the height of the display screen is changed.

As shown in fig. 6, since the user needs to control the lifting of the display screen and the movement of the support by holding the handle 4, in some embodiments, the outer opening edge of the second chute 22 is provided with a silica gel strip 6, and the silica gel strip 6 extends along the opening edge of the chute and is closed, so that the problem of scratching the hand caused by sharpness of the opening edge of the chute is prevented. Instead of the strip of silicon 6, other common elastic elements, such as foam, may be used.

Referring to fig. 7 to 10, in some embodiments, the handle 4 includes a grip portion 41 and an extension portion 42, the extension portion 42 being connected to a side of the grip portion 41 adjacent to the slider 5; the extension part 42 is provided with a first assembly hole 421, the holding part 41 is provided with an assembly slot 411, and the sliding block 5 is provided with a second assembly hole 51 corresponding to the first assembly hole 421; the handle 4 and the slider 5 are fixed by a fastener which passes through the fitting slot 411, the first fitting hole 421, and is fixed to the second fitting hole 51 in this order. Wherein, the fastener is, for example, a screw, and correspondingly, the second assembly hole 51 is a threaded hole, the first assembly hole 421 is opposite to the second assembly hole 51, and when assembling, the screw enters from the assembly slot 411, passes through the first assembly hole 421, and then is screwed into the second assembly hole 51 to be fixed, thereby fastening the handle 4 and the slider 5 together.

With continued reference to fig. 7, in other embodiments, the extending portion 42 of the handle 4 is provided with a plurality of limiting protrusions 422 (2 limiting protrusions are illustrated in fig. 7) on a side facing the slider 5, and as shown in fig. 10, the slider 5 is provided with limiting holes 52 corresponding to the limiting protrusions 422 one by one, and the limiting protrusions 422 are blocked into the corresponding limiting holes 52 when the extending portion 42 of the handle is assembled and connected with the slider 5. Alternatively, the limiting protrusion 422 may be disposed on the slider 5, and the limiting hole 52 may be disposed on a side of the extension 42 near the slider 5. The limit protrusion 422 cooperates with the limit hole 52 to limit the handle 4 and the slide 5 in advance, so that the subsequent fastener can pass through the first assembly hole 421 and the second assembly hole 51 conveniently to realize assembly.

In some embodiments, the extension portion 42 of the handle 4 extends from the holding portion 41 toward the slider 5, and the top surface and/or the bottom surface of the extension portion 42 is provided with a dovetail groove 423 along the extending direction (the bottom surface is provided with a dovetail groove as shown in fig. 7), and the dovetail groove 423 extends to a surface of the extension portion 42 facing the side of the slider 5. Correspondingly, the limit post 53 which is matched with the dovetail groove 423 is fixed on the sliding block 5, the shape of the limit post 53 is matched with the shape of the dovetail groove 423, and the limit post 53 is clamped into the dovetail groove 423 when the extension part 42 of the handle 4 is assembled and connected with the sliding block 5, so that the bottom and/or the top of the handle 4 are supported, the stress area of the handle 4 and the sliding block 5 when the handle 4 is lifted is increased, the stress of a fastener is shared, and the stability of the handle when the force is transferred to the sliding block is improved. In a further embodiment, a groove adapted to the limit post 53 may be formed on the slider 5 for loading the limit post 53, referring to fig. 10, a portion of the limit post 53 after being loaded into the groove protrudes from the surface of the slider 5, and a portion of the limit post 53 protruding from the slider 5 is the same as or approximately the same as the length of the extension portion 42 of the handle 4, when the handle 4 is mounted on the slider 5, the front end surface of the grip portion 41 of the handle 4 (i.e. the end surface of the connection extension portion 42) may abut against the limit post 53, so that the limit post 53 is fixed between the grip portion and the slider without dropping, and thus the limit post 53 itself may be used as a detachable part without being integrally formed with the slider 5, thereby reducing the difficulty of preparation and improving the convenience of assembly.

Referring to fig. 11, which is a schematic view of a display screen bracket according to another embodiment of the present utility model, the main difference from the previous embodiment is that the handle 4 of the previous embodiment is disposed on the back of the supporting rod 3, whereas in the embodiment shown in fig. 11, the handle 4 is disposed on the side of the connecting rod 3, and correspondingly, the second sliding groove 22 'is also located on the side opposite to the first sliding groove 21, and the handle 4 is fixed to the sliding block 5 in the supporting rod 3 through the second sliding groove 22'. Other structures and working principles are the same as those of the foregoing embodiments, and are not described herein.

Referring to fig. 12, a schematic view of a display screen bracket according to another embodiment of the present utility model is shown, in which the holding portion 41 'of the handle 4' is also located at the back of the supporting rod 2, that is, located at two opposite sides of the supporting rod 2 with the connecting rod 3 respectively, the supporting rod 2 is provided with a first sliding groove 21 extending along the axial direction thereof, a sliding rail is disposed in the supporting rod 2 and is communicated with the first sliding groove 21, and the connecting rod 3 is fixed on the sliding block 5 through the first sliding groove 21; the handle 4' includes a grip portion 41' and an extension portion 42', wherein one end of the extension portion 42' extends around the circumference of the strut 2 to be fixedly connected to the connecting rod 3, and the other end is connected to the grip portion 41'. In this embodiment, the handle 4' is fixedly connected with the connecting rod 3, and when the handle 4' is operated to lift, the acting force is directly transmitted to the connecting rod 3 by the handle 4', and then transmitted to the sliding block 5 connected with the connecting rod 3, so that the sliding block 5 can move up and down along the sliding rail to realize lifting.

The display screen bracket of the embodiment of the utility model not only can realize the lifting function through the handle operation, but also can simultaneously have the rotating function, namely, the synchronous rotation of the connecting rod 3 can be realized through rotating the handle 4, so that the display screen is rotated. Specifically, referring to fig. 12, the connecting rod 3 and/or the handle 4 are connected to the strut 2 in a damped rotation manner, and in the case that the handle 4 and the connecting rod 3 are fixed relatively, rotation of the connecting rod 3 relative to the strut 2 can be achieved by rotating the handle 4, and in this embodiment, the lifting and rotating structure of the connecting rod 3 relative to the strut 2 can exist simultaneously.

In other embodiments, it is also possible to connect the connecting rod 3 with the slider 5 in a damped rotational manner, while the handle 4 is fixed to the connecting rod 3.

In other embodiments, the rod 2 may not be provided with a sliding rail and a sliding block 5, so that the connecting rod 3 and the handle 4 only have a rotation function relative to the rod 2, at this time, the handle 4 is directly fixedly connected with one end of the connecting rod 3 close to the rod 2, and the connecting rod 3 or the handle 4 is in damped rotation connection with the rod 2, wherein the specific connection mode can refer to the connection mode of the handle 4 and the sliding block 5 in the previous embodiment, the structure of the handle 4 is unchanged, and each structural design matched with the extension part 42 of the handle 4 on the sliding block 5 is transferred to the rear end of the connecting rod 3, so that the handle 4 is assembled and fixed with the rear end of the connecting rod 3. In this implementation, the connecting rod 3 and/or the handle 4 is connected to the strut 2 in a damped rotation manner, and the rotation of the display screen is achieved by rotating the handle 4 to rotate the connecting rod 3. The specific damping rotation connection structure can be of conventional design, and will not be described in detail herein.
