[0027] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0028] like Figures 1 to 7 As shown, an embodiment of this utility model provides a base. The base includes: a base 10; a moving component disposed on the base 10, the moving component including a plurality of rolling members 20, each rolling member 20 including a linkage member 21 and a rolling member 22, the rolling member 22 being rotatably disposed on the linkage member 21, the linkage member 21 being rotatably disposed on the base 10, the rotation axis of the linkage member 21 being set at an angle to the rotation axis of the rolling member 22; and an adjusting component including an adjusting member 31 and a toggle member 32 connected to the adjusting member 31, the adjusting member 31 being rotatably disposed relative to the base 10, the adjusting member 31 being linked with the plurality of linkage members 21, and the toggle member 32 extending to the peripheral edge of the base 10, the adjusting member 31 being rotated by operating the toggle member 32 to lock and unlock the moving component.

[0029] In the above technical solution, when the moving assembly needs to be locked, the adjusting member 31 is driven to rotate relative to the base 10 by operating the push member 32 located at the side edge of the base 10. Since the adjusting member 31 and the plurality of link members 21 are linked, the adjusting member 31 can limit the rotation of the plurality of rolling members 22 through the plurality of link members 21, so as to achieve the locking of the moving assembly and the locking of the base. When the moving assembly needs to be unlocked, the adjusting member 31 is driven to rotate relative to the base 10 by operating the push member 32 again. The adjusting member 31 removes the limitation on the plurality of rolling members 22 through the plurality of link members 21, so that the plurality of rolling members 22 can rotate freely. After the moving assembly is unlocked, the base can move freely. Compared with the prior art, the present application only needs to operate the push member 32, and the brake can be applied without turning over the entire base. The locking and unlocking of the base can be achieved, the operation process is simplified, and the operation convenience is improved. On the other hand, in the prior art, the brake structure can be directly arranged on the caster for the base with casters. However, for the moving base with low casters, the operation space is limited, and the brake structure in the prior art is difficult to apply. The structure of the present application effectively solves the brake problem of the moving base with low casters, and the structure of the present application almost does not increase the height of the base, so that the thinness and beauty of the base can be well guaranteed.

[0030] As shown in Figure 4 In the embodiment of the present application, the adjusting member 31 comprises: a rotating disc 311 rotatably arranged on the base 10; a plurality of tooth segments 312 arranged on the rotating disc 311 in a circumferential direction, and the outer periphery of the link member 21 is provided with a meshing tooth, and the plurality of tooth segments 312 are arranged in meshing correspondence with at least two link members 21.

[0031] In the above technical solution, when the moving assembly is in the unlocked position, the tooth segments 312 on the rotating disc 311 are separated from the meshing teeth on the linkage 21, allowing the linkage 21 to rotate freely, so that the rollers 222 can freely roll, and the base is in a movable state; the user operates the push member 32 to rotate the rotating disc 311, and in the rotating process, the tooth segments 312 on the rotating disc 311 gradually contact and mesh with the meshing teeth on the linkage 21, thereby driving the linkage 21 to rotate, when the rotating disc 311 is rotated to the position, the plurality of tooth segments 312 are fully meshed with the meshing teeth on the at least two linkages 21, at this time, the positions of the rollers 222 are fixed and cannot roll, thereby achieving the locking of the base. At this time, the base is in a stable state and will not move due to external force. When unlocking is needed, the user reversely rotates the rotating disc 311, the tooth segments 312 gradually separate from the meshing teeth on the linkage 21, restoring the free rotation of the linkage 21 and the rollers 222, the base is unlocked, and the moving ability is restored. In this way, the rotation of the rotating disc 311 controls the rollers 222 on the plurality of linkages 21, achieving quick locking or unlocking, so that the user only needs to perform one operation to simultaneously control a plurality of rolling members, greatly improving the efficiency of locking and unlocking of the base.

[0032] As shown in Figures 4 to 6 In the embodiment of the utility model, a plurality of tooth segments 312 and a plurality of linkages 21 are one-to-one meshing arrangement, when the moving assembly is in the locked state, the directions of any adjacent two rolling members 22 in the plurality of rolling members 22 are different, when the moving assembly is in the unlocked state, the directions of the plurality of rolling members 22 are same, and / or a plurality of tooth segments 312 and a plurality of linkages 21 are one-to-one meshing arrangement, when the adjusting member 31 is rotated by operating the push member 32, the plurality of tooth segments 312 and the plurality of linkages 21 are one-to-one corresponding meshing.

[0033] In the above technical solution, when the moving assembly is in the locked state, the directions of any adjacent two rolling members 22 in the plurality of rolling members 22 are different, in this way, the rotating directions of the plurality of rolling members 22 are different, and the rolling members 22 in different directions can provide multi-directional frictional resistance, which can avoid the movement of the base, and can ensure that the product is stable on uneven or inclined surface.

[0034] Further, when the adjusting member 31 is rotated by operating the push member 32, the plurality of tooth segments 312 and the plurality of linkages 21 are one-to-one corresponding meshing, which can make the plurality of linkages 21 rotate one by one, thereby making the directions of the plurality of linkages 21 different.

[0035] Furthermore, by operating the toggle member 32, the user can control the orientation of the multiple rolling members 22 through the engagement of multiple tooth segments 312 with multiple linkage members 21, thereby realizing the switching between the locked and unlocked states of the base.

[0036] It should be noted that in the embodiments of this utility model, when the moving component is in the locked position, multiple tooth segments 312 are engaged with multiple linkage members 21 in a one-to-one correspondence; when the moving component is in the unlocked position, multiple tooth segments 312 are not engaged with multiple linkage members 21. In this way, the tooth segments 312 can release the linkage members 21, thereby avoiding restrictions on the linkage members 21 and the rolling members 22.

[0037] like Figures 4 to 6 As shown in the embodiments of this utility model, the lengths of the multiple tooth segments 312 in the circumferential direction of the turntable 311 are different; and / or, the spacing between any two adjacent tooth segments 312 among the multiple tooth segments 312 is different.

[0038] With the above configuration, the lengths and spacings of the multiple tooth segments 312 on the turntable 311 are designed differently. Thus, when the adjusting component 31 rotates, the multiple tooth segments 312 do not mesh simultaneously with the multiple linkages 21, but rather they mesh one by one. The adjusting component 31 can drive the multiple linkages 21 to rotate to different angles; that is, the rotation angles of each linkage 21 are different. This ensures that the orientation sequence of the multiple rolling elements 22 is disrupted, resulting in different orientations for the multiple rolling elements 22. This prevents the base from shifting in a particular direction simply because all the rolling elements 22 are facing the same direction. When the adjusting member 31 is in the locked position, the tooth segments 312 of different lengths mesh with the corresponding linkage members 21. Since the multiple linkage members 21 rotate at different angles, the rolling members 22 connected to each linkage member 21 are oriented differently, thereby generating friction in multiple directions to achieve the locking effect. In the unlocked state, by rotating the adjusting member 31, the multiple tooth segments 312 and multiple linkage members 21 are no longer meshed. In this way, the user can easily push the product without encountering resistance caused by inconsistent orientation, thus improving the efficiency and smoothness of movement.

[0039] Preferably, in an embodiment of the present invention, a plurality of rolling members 20 are evenly spaced along the circumference of the turntable 311.

[0040] In one embodiment, along the circumference of the turntable, the distances from the axes of the multiple linkages 21 to the multiple tooth segments are different, so that when the turntable is rotated, the multiple linkages 21 begin to mesh with the multiple tooth segments at different times.

[0041] like Figure 5As shown in the embodiment of this utility model, multiple tooth segments 312 are disposed on the outer periphery of the turntable 311, and multiple rolling members 20 are located on the outer periphery of the adjusting member 31.

[0042] In the above technical solution, by centrally arranging multiple tooth segments 312 on the outer periphery of the turntable 311, the user only needs to rotate the turntable 311 to control the locking and unlocking states of the corresponding multiple rolling components 20, thereby simplifying the control process of the entire moving component and improving the convenience and efficiency of operation.

[0043] Specifically, in the embodiments of this utility model, when the moving component is in the locked state, multiple tooth segments 312 on the outer periphery of the turntable 311 engage with the linkages 21 on multiple rolling components 20, and the rollers 222 of each rolling component 20 face different directions. This effectively prevents the base from moving in a certain direction, thereby enhancing the overall stability and safety. In the unlocked state, the adjusting component 31 no longer restricts the multiple linkages 21, allowing the rollers 222 of all rolling components 20 to face the same direction. This enables the moving component to move smoothly in any direction, improving the product's moving efficiency and the user's experience.

[0044] In one embodiment, multiple tooth segments 312 may also be disposed on the inner periphery of the turntable 311, and multiple rolling members 20 may be located on the inner periphery of the adjusting member 31.

[0045] like Figure 3 , Figure 5 and Figure 6 As shown in the embodiment of this utility model, the rolling element 22 includes a mounting shaft 221 and rollers 222 rotatably disposed on the outer periphery of the mounting shaft 221. Both ends of the mounting shaft 221 are mounted on the linkage element 21, and at least a portion of the rollers 222 protrude from the surface of the linkage element 21 facing away from the base 10. The side of the linkage element 21 facing away from the base 10 is provided with a receiving groove 211 and two mounting grooves 212 communicating with the receiving groove 211. Both ends of the mounting shaft 221 are engaged with the two mounting grooves 212, and a portion of the rollers 222 are located in the receiving groove 211.

[0046] In the above technical solution, by setting the rolling element 22 to include a mounting shaft 221 and a roller 222, and making at least a portion of the roller 222 protrude from the surface of the linkage element 21 on the side away from the base 10, the protruding roller 222 can form a contact area with the ground so that the base can move or stop.

[0047] Furthermore, the linkage 21 is provided with a receiving groove 211 and two mounting grooves 212 communicating with the receiving groove 211, so that the mounting shaft 221 and the linkage 21 form a snap-fit ​​engagement. This structure not only facilitates assembly and disassembly, but also provides a smoother path for the movement of the roller 222.

[0048] Further, part of the roller 222 is located in the accommodating groove 211, so that the roller 222 can be partially hidden when not in use, thereby saving space and maintaining the overall appearance of the product.

[0049] As shown in Figure 3 , Figure 5 , Figure 6 and Figure 7 , in the embodiment of the utility model, the rolling member 20 further includes a mounting piece 23 mounted on the base 10, the mounting piece 23 has a mounting cavity, one end of the linkage member 21 is rotationally matched with the mounting cavity, the other end of the linkage member 21 extends out of the mounting cavity and is linked with the adjusting member 31; the rolling member 20 further includes a plurality of rolling balls 24, the plurality of rolling balls 24 are mounted between the linkage member 21 and the inner wall of the mounting cavity, the mounting piece 23 and the linkage member 21 are in rolling contact with the rolling balls 24; and / or, the bottom wall of the mounting cavity is provided with a first buckle 25, the linkage member 21 is provided with a first clamping groove 26, the first buckle 25 is clamped in the first clamping groove 26 and rotationally matched with the first clamping groove 26.

[0050] In the above technical scheme, on the one hand, by mounting a plurality of rolling balls 24 between the linkage member 21 and the inner wall of the mounting cavity, rolling contact between the linkage member 21 and the mounting piece 23 during rotation is realized, the design of the rolling balls 24 reduces the friction force of the linkage member 21 during rotation, and user experience is improved; on the other hand, the bottom wall of the mounting cavity is provided with a first buckle 25, which is clamped and rotationally matched with the first clamping groove 26, which not only ensures the stable position of the linkage member 21 in the mounting cavity, but also enables the linkage member 21 to rotate.

[0052] In the above technical solution, when the moving assembly needs to be locked, the handle member 33 is moved from the storage position at the bottom of the base 10 to the use position, the handle member 33 drives the actuating member 32 to rotate, the actuating member 32 drives the adjusting member 31 to rotate relative to the base 10, the tooth segment 312 on the rotating disc 311 starts to contact and gradually engages with the meshing teeth on the linkage 21, so as to drive the rotation of the plurality of linkages 21 to different angles, thereby achieving the locking of the moving assembly, and the handle member 33 is switched from the use position to the storage position by operation; when the moving assembly needs to be unlocked, the handle member 33 is moved from the storage position at the bottom of the base 10 to the use position, the handle member 33 drives the actuating member 32 again, so that the adjusting member 31 rotates relative to the base 10, the tooth segment 312 on the rotating disc 311 gradually disengages from the meshing teeth on the linkage 21, the restriction of the linkage 21 is released, the roller 222 can freely roll, so that the base is freely moved, and then the handle member 33 is switched from the use position to the storage position.

[0053] Specifically, in the embodiment of the utility model, the handle member 33 is designed so that the user can easily and intuitively control the locking and unlocking state of the base, and the quick unlocking and locking of the roller 222 can be realized by simply operating the handle member 33, without a complex operation process, thereby improving the convenience of operation.

[0054] Specifically, in the embodiment of the utility model, the handle member 33 can be stretched out from the bottom of the base 10 when in use, and is stored in the base when not in use, so that the aesthetic appearance of the base is maintained, and the space occupation problem and collision risk caused by the exposure of the handle member 33 are avoided.

[0056] Through the above arrangement, whether the base is in the free moving state or the brake state, that is, whether the moving assembly is in the unlocked position or the locked position, the handle member 33 can be stored at the bottom of the base 10.

[0057] Specifically, the handle member 33 is further provided with a through hole, one end of the actuating member 32 away from the rotating disc 311 is also provided with a through hole, and the base further comprises a rotating shaft, and the actuating member 32 and the handle member 33 are connected through the rotating shaft.

[0058] As shown in Figure 3 , Figure 4 and Figure 6 , the base comprises an arc-shaped limiting portion 51 and a limiting piece 52 in sliding cooperation with the arc-shaped limiting portion 51, the arc-shaped limiting portion 51 extends around the rotation axis of the adjusting member 31, one of the base 10 and the adjusting member 31 is provided with the arc-shaped limiting portion 51, and the other of the base 10 and the adjusting member 31 is provided with the limiting piece 52.

[0059] In the above technical solution, on the one hand, the limiting piece 52 is arranged in sliding cooperation with the arc-shaped limiting portion 51, the limiting piece 52 slides in the arc-shaped limiting portion 51, the arc-shaped limiting portion 51 can realize the guiding effect, and the adjusting member 31 rotates around the axis of the arc-shaped limiting portion 51; on the other hand, the cooperation mechanism of the arc-shaped limiting portion 51 and the limiting piece 52 effectively limits the rotation range of the adjusting member 31, prevents excessive rotation of the adjusting member 31 in the operation process, and avoids the risk of adjustment failure or component damage caused by excessive rotation. Wherein, the adjusting member 31 rotates relative to the base 10, the adjusting member 31 is continuously rotated to make the limiting piece 52 contact one side edge of the arc-shaped limiting portion 51, the adjusting member 31 stops rotating, the tooth segment 312 on the rotating disc 311 is in meshing state with the meshing teeth on the linkage 21, so as to limit the rotation of the linkage 21, in this way, the rolling of the roller 222 is also limited, so as to realize the locking of the moving assembly; the adjusting member 31 is rotated again relative to the base 10, the limiting piece 52 slides in the arc-shaped limiting portion 51, the adjusting member 31 is continuously rotated to make the limiting piece 52 contact the other side edge of the arc-shaped limiting portion 51, the adjusting member 31 stops rotating, the tooth segment 312 on the rotating disc 311 is no longer in meshing state with the meshing teeth on the linkage 21, in this way, the rotation of the linkage 21 is no longer limited, the roller 222 can freely roll, so as to make the base freely move.

[0060] Preferably, in the embodiment of the utility model, the adjusting member 31 is provided with the arc-shaped limiting portion 51, the number of arc-shaped limiting portions 51 is multiple, the limiting piece 52 is arranged on the base 10, and the number of limiting pieces 52 is also multiple, the multiple arc-shaped limiting portions 51 are arranged at intervals along the circumference of the rotating disc, and the multiple limiting pieces 52 are arranged at intervals along the circumference of the rotating disc.

[0061] Specifically, compared with the conventional base, the base of the embodiment of the utility model only has a rotating disc 311 with multiple tooth segments 312, and the locking and unlocking requirements can be realized at a lower cost.

[0062] As Figure 1 The embodiment of the utility model discloses, because linkage 21 sets up in the one side of the base that deviates from stand 2, linkage 21 hides inside the base, like this, it is more beautiful, and only in the edge of base leaks out a handle member 33 that can rotate, the user is convenient and rotates and carries out operation.

[0063] Specifically, the utility model discloses, a plurality of cooperation slots 12 are arranged on the base, and the mounting piece 23 is tightly fitted and fixed with the cooperation slot 12, and a plurality of tooth segments 312 are unevenly distributed on the rotating disc 311, so that the rotating disc 311 is not engaged with the plurality of linkage 21 simultaneously when rotating, so that the angles of rotation of the plurality of linkage 21 are different, the orientation order of the plurality of rollers 222 can be ensured to be disturbed, and the base can not be moved in a direction due to the plurality of rollers 222 being oriented in the same direction.

[0064] Specifically, the utility model discloses, the outer periphery of mounting piece 23 is equipped with cooperation rib, and is tightly fitted and fixed with cooperation slot 12, and the outer periphery of roller 222 is equipped with antiskid pad 223, so that the roller 222 can have greater friction with the ground in the locked state, and the locking effect is enhanced.

[0065] As Figure 1 The embodiment of the utility model provides a display support, including above-mentioned base 1, set up in base 1's stand 2 and with stand 2 connection's support head 3, wherein, support head 3 is used to support display.

[0066] The display support has all the advantages of the above-mentioned base 1, which will not be repeated here.

[0067] From the above description, it can be seen that the above-mentioned embodiments of the utility model realize the following technical effects: when the moving assembly needs to be locked, the knob member located on the side edge of the base is operated, and the knob member drives the adjusting member to rotate relative to the base. Since the adjusting member and the plurality of linkage members are connected, the adjusting member can limit the rotation of the plurality of rollers through the plurality of linkage members, and the locking of the moving assembly can be realized to achieve the effect of locking the base. When the moving assembly needs to be unlocked, the knob member is operated again to make the adjusting member rotate relative to the base. The adjusting member removes the restriction on the plurality of rollers through the plurality of linkage members, and the plurality of rollers can rotate freely.
