[0063] Display screens are used in conjunction with computer hosts and are important equipment in the information age. They mainly provide the function of converting computer signals into corresponding images for easy viewing. The display screen body is fixed on an office desk or computer desk by a display screen bracket. In some cases, multiple display screens are required for use.

[0064] In the related art, the installation of display screens requires the installation of mounting brackets according to the overall height, and part of the display screen needs to be installed in the air. For some large and heavy display screens, it is difficult for one person to operate, which makes the overall installation slow; at the same time, the risk of installing display screens in the air is relatively high. Once problems occur during the installation process, it is easy to cause the display screen to fall and bump, which will cause damage to the display screen and add unnecessary economic burden.

[0065] The present invention proposes a combined bracket and a display device, aiming to at least solve the technical problem in the related art that when a display screen bracket is equipped with a display screen, it needs to be installed in the air, which involves certain risks.

[0066] See also Figure 1 , Figure 2 and Figure 3In one embodiment of the present invention, the combined bracket 100 includes at least two mounting frames 1 and a lifting device 4, each mounting frame 1 is provided with a mounting portion 11 for mounting a display device 200, and the at least two mounting frames 1 include a first mounting frame 101 and a second mounting frame 102, the first mounting frame 101 is provided with a docking structure 2 arranged upward, and the second mounting frame 102 is provided with a matching structure 3 arranged downward, at least one of the first mounting frame 101 and the second mounting frame 102 can be movably arranged in a horizontal direction, and the second mounting frame 102 can be movably arranged in an up-and-down direction; the lifting device 4 is used to drive the second mounting frame 102 to move up and down; wherein the matching structure 3 is used to cooperate with the docking structure 2 when the second mounting frame 102 is located above the first mounting frame 101, so as to support the second mounting frame 102 on the first mounting frame 101.

[0067] In the technical solution of the embodiment of the present invention, there are at least two mounting frames 1, each mounting frame 1 is provided with a mounting portion 11 for mounting the display device 200. After the display device 200 is mounted on the corresponding mounting portion 11, the second mounting frame 102 is driven to rise to the bottom thereof to accommodate the first mounting frame 101 through the lifting device 4. Through the horizontal movement of one of the mounting frames 1, the second mounting frame 102 and the first mounting frame 101 can be distributed up and down, and then the second mounting frame 102 is supported on the first mounting frame 101 through the docking structure 2 and the matching structure 3. When the number of mounting frames 1 is more, the above steps are repeated in sequence, and multiple display devices 200 can be stacked and installed in the height direction without aerial operations, thereby reducing risks.

[0068] When disassembly is required, the cooperation between the docking structure 2 and the matching structure 3 is released, and then one of the mounting frames 1 is moved in the horizontal direction to stagger the first mounting frame 101 and the second mounting frame 102, and the second mounting frame 102 can be driven to descend by the lifting device 4. In this way, there is no need to perform aerial operations during disassembly, and the risk is smaller.

[0069] This design does not limit the number of mounting brackets 1, and the number of mounting brackets 1 can be three or more. Figures 1 to 5 When the number of mounting frames 1 is three, that is, there is also a third mounting frame 103, no matter whether the third mounting frame 103 is finally located above the second mounting frame 102 or below the first mounting frame 101, when the first mounting frame 101 and the second mounting frame 102 are installed in the up and down directions, the second mounting frame 102 must be driven to rise by the lifting device 4 so that the matching structure 3 set downward on the second mounting frame 102 cooperates with the docking structure 2 on the first mounting frame 101 to realize the stacking installation of the first mounting frame 101 and the second mounting frame 102.

[0070] In order to allow the first mounting frame 101 and the second mounting frame 102 to overlap in the vertical direction for connection, either the first mounting frame 101 or the second mounting frame 102 can be movable. In an embodiment of the present application, the first mounting frame 101 and the second mounting frame 102 are arranged in the horizontal direction, and the second mounting frame 102 can be movably arranged in the horizontal direction; the second mounting frame 102 has a waiting position and a working position. When in the waiting position, the second mounting frame is located on one side of the first mounting frame 101 in the horizontal direction, and when in the working position, the second mounting frame is located on the upper side of the first mounting frame 101, and the docking structure 2 cooperates with the matching structure 3 to support the second mounting frame 102 above the first mounting frame 101; in this way, the first mounting frame 101 and the second mounting frame 102 are overlapped in the vertical direction by the horizontal movement of the second mounting frame 102.

[0071] It should be noted that the waiting position is the position where each mounting frame 1 is used to mount the display device 200. Figure 1 As shown, in the waiting position, each mounting frame 1 is arranged in a horizontal direction, and no high-altitude operation is required when installing the display device 200; Figure 4 As shown in the figure (the display device 200 on each mounting frame 1 is hidden in the figure, and only the position relationship of each mounting frame 1 is shown), the working position is the position where each mounting frame 1 is stacked in the vertical direction after the display device 200 is installed. As can be seen from the above, the number of mounting frames 1 is at least two, and can be three or more. The first mounting frame 101 and the second mounting frame 102 are not specific, but refer to two adjacent mounting frames 1. Figure 1 and attached Figure 4 When in the waiting position, the third mounting frame 103 is located on one side of the second mounting frame 102 in the horizontal direction. When in the working position, the third mounting frame 103 is located on the upper side of the second mounting frame 102. In the process of switching from the waiting position to the working position, the third mounting frame 103 is first driven upward by the lifting device 4, and then the third mounting frame 103 moves horizontally to the upper side of the second mounting frame 102, and then the third mounting frame 103 is supported above the second mounting frame 102 through the cooperation of the docking structure 2 and the matching structure 3.

[0072] In order to realize the movement of the second mounting frame 102, in the embodiment of the present application, please refer to Figure 1 and Figure 4The combined bracket 100 also includes a base 5 and a sliding seat 6 that slides with the base 5 in the horizontal direction. The first mounting frame 101 is arranged on the base 5, and the lifting device 4 is arranged on the sliding seat 6. In this way, the second mounting frame 102 is driven to move in the horizontal direction by the movement of the lifting device 4 in the horizontal direction, and the sliding can be guided by the cooperation of the base 5 and the sliding seat 6. The present design is not limited to this. In some embodiments, the lifting device 4 can be kept fixed, and the second mounting frame 102 can move in the horizontal direction relative to the lifting device 4. In contrast, if the number of mounting frames 1 is small, there will be no problem. If the number of mounting frames 1 is large, the mounting frame 1 connected to the lifting device 4 will need to move in the horizontal direction for a longer distance, and the more connections, the greater the pressure on the lifting device 4, which can easily cause the overall center of gravity of the lifting device 4 to shift and cause damage. If the lifting device 4 slides as a whole, there will be no such problem.

[0073] There are many lifting forms of the lifting device 4. In some embodiments, the lifting device 4 can use a pulley and a suspension rope structure to realize the rise of the second mounting frame 102. The pulley has two forms: a fixed pulley and a movable pulley. Although the movable pulley can save effort, it requires the installer to work in the air at a higher altitude. Therefore, only the fixed pulley can be used. However, the fixed pulley does not save effort, and it is difficult to lift multiple mounting frames 1 entirely by manpower. In an embodiment of the present invention, the lifting device 4 includes a second screw rod 41 and a lifting platform 42. The second screw rod 41 extends in the up and down direction and is rotatable. The lifting platform 42 is threadedly connected to the second screw rod 41, wherein the second mounting frame 102 is arranged on the lifting platform 42; in this way, by rotating the second screw rod 41, the lifting platform 42 is driven to move up and down by a threaded transmission method, thereby driving the second mounting frame 102 to move up and down, which is more labor-saving. At the same time, the threaded structure has a certain self-locking property, and there is no need to keep the tension of the suspension rope like a fixed pulley. The threaded lifting method is more convenient.

[0074] Specifically, when the lifting device 4 is slidably connected to the base 5 via the sliding seat 6 , the second screw rod 41 is rotatably disposed on the sliding seat 6 .

[0075] If the second screw 41 is connected to the lifting platform 42 by a thread only, when the second screw 41 is rotated, in order to make the lifting platform 42 move upward or downward, the installer needs to hold the lifting platform 42, which brings inconvenience to the actual installation. Therefore, in the embodiment of the present application, please refer to Figure 5 The lifting device 4 also includes a second limiting rod 43, and the lifting platform 42 is slidably installed on the second limiting rod 43 along the up and down directions; the second limiting rod 43 can limit the lifting platform 42 from rotating with the second screw rod 41.

[0076] It is understandable that the second screw rod 41 extends in the longitudinal direction. When the second screw rod 41 is rotated, it is difficult to rotate a full circle at one time, which will lead to a low efficiency of the overall installation. Therefore, in the embodiment of the present application, please refer to Figure 8 A turntable is rotatably arranged on the sliding seat 6, and bevel gears are arranged on the turntable and the second screw 41. The two bevel gears mesh to change the rotation direction. It is only necessary to arrange a protruding handle on the side of the turntable away from the second screw 41 to easily realize the rotation of the second screw 41.

[0077] It should be noted that no matter whether the lifting device 4 adopts the form of threaded structure lifting or pulley structure lifting, if the upward supporting force on the second mounting frame 102 is always maintained, it is easy to cause damage to the lifting device 4. Therefore, in the embodiment of the present application, the lifting platform 42 and the second mounting frame 102 can be separately arranged. After the first mounting frame 101 and the second mounting frame 102 are installed, the lifting platform 42 is separated from the second mounting frame 102, and it will not play a supporting role for the second mounting frame 102. The overall structure is supported by the ground or the table, thereby reducing the possibility of damage to the lifting device 4.

[0078] There are many ways to separate the lifting platform 42 from the second mounting frame 102. In the embodiment of the present application, please refer to Figure 5 , the lifting platform 42 has a mounting groove 421 with an opening facing upward, and the second mounting frame 102 is at least partially placed in the mounting groove 421, so that the second mounting frame 102 and the lifting platform 42 can be separated; in this way, when the lifting platform 42 needs to be separated from the second mounting frame 102, it is only necessary to rotate the second screw 41 to make the lifting platform 42 move downward, and the second mounting frame 102 is disengaged from the mounting groove 421, so that the lifting platform 42 can be separated from the second mounting frame 102. In another embodiment, the lifting platform 42 can be connected to the second mounting frame 102 by a transverse plug-in manner. When separation is required, it is only necessary to control the overall lifting device 4 to slide in a direction away from the second mounting frame 102 until it is separated. However, in comparison, the setting of the mounting groove 421 makes the installation of the second mounting frame 102 and the lifting platform 42 more convenient.

[0079] The lifting device 4 can directly drive the second mounting frame 102 or indirectly drive it. For example, when the third mounting frame 103 in the figure is finally located above the second mounting frame 102, the third mounting frame 103 is first driven upward by the lifting device 4. After the third mounting frame 103 is connected to the second mounting frame 102, the lifting device 4 can still act on the third mounting frame 103 to drive the second mounting frame 102 to rise through the third mounting frame 103, or the lifting device 4 acts on the second mounting frame 102 to directly drive the second mounting frame 102 to rise.

[0080] In order to improve the display effect of the display device 200 after the first mounting frame 101 and the second mounting frame 102 are installed, in the embodiment of the present application, the combined bracket 100 further includes a support shaft 7, the lower end of the support shaft 7 is connected to the base 5, and the upper end is connected to the first mounting frame 101; the first mounting frame 101 is rotatably connected to the support shaft 7, or the support shaft 7 is rotatably connected to the base 5. In this way, the first mounting frame 101 and the second mounting frame 102 can be rotated as a whole, driving the angle change of the display device 200, and improving the display effect.

[0081] It is understandable that the height dimensions of different display devices 200 are not the same. If the first mounting frame 101 and the second mounting frame 102 are stacked up and down, the distance between the two is fixed. If the height dimension of the display device 200 is too large, it will cause the corresponding two display devices 200 to collide; if the height dimension of the display device 200 is small, it will cause the distance between the two display devices to be too large and affect the appearance. Therefore, in the embodiment of the present invention, when the matching structure 3 is matched with the docking structure 2, the distance between the second mounting frame 102 and the first mounting frame 101 can be adjusted; in this way, when the second mounting frame 102 and the first mounting frame 101 are stacked up and down, the distance between the second mounting frame 102 and the first mounting frame 101 can be adjusted to adapt to display devices of different heights.

[0082] There are many methods for adjusting the distance between the first mounting frame 101 and the second mounting frame 102. For example, the adjustment can be achieved by adjusting the height position relationship between the first mounting frame 101 and the docking structure 2. In the embodiment of the present invention, the second mounting frame 102 and the matching structure 3 can be adjusted up and down, and the matching structure 3 is supported on the docking structure 2. Compared with the height position relationship between the first mounting frame 101 and the docking structure 2, since the docking structure 2 needs to support the second mounting frame 102 and the display device 200 thereon, the adjustment will be more affected by the structural gravity factor. By adjusting the height position relationship between the second mounting frame 102 above and the matching structure 3, the gravity that needs to be overcome is smaller, and the adjustment is more convenient.

[0083] There are many ways to adjust the height position relationship between the matching structure 3 and the second mounting bracket 102. In some embodiments, please refer to Figure 3, the matching structure 3 includes a first screw rod 31, and the second mounting frame 102 is threadedly connected to the first screw rod 31. The first screw rod 31 is supported by the docking structure 2 and can be rotatably arranged. In this arrangement, since the docking structure 2 can support the first screw rod 31, when the first screw rod 31 is rotated, the second mounting frame 102 can be driven to rise or fall through the thread transmission, thereby adjusting the distance between the first mounting frame 101 and the second mounting frame 102 to adapt to display devices of different height sizes. The adjustment method is not limited to this. In some embodiments, the overall matching structure 3 can slide relative to the second mounting frame 102, and the second mounting frame 102 is fixed by a fixing structure after sliding, such as a latch and a buckle. However, it is often impossible to achieve stepless adjustment, and the installer needs to support the weight of the second mounting frame 102 and the display device thereon with his hands. The threaded method is more labor-saving and can achieve stepless adjustment.

[0084] There are many ways for the docking structure 2 to support the first screw rod 31. For example, a rotation groove may be directly opened above the first mounting frame 101 to allow the first screw rod 31 to rotate. However, it is troublesome for the rotation groove and the first screw rod 31 to be fixed after adjustment. In some embodiments, please refer to Figure 3 The docking structure 2 includes a first docking rod 21 rotatably arranged on the first mounting frame 101, and the first docking rod 21 is detachably connected to the first screw rod 31. In this way, the first docking rod 21 supports the first screw rod 31, and it is relatively easier to fix the two rod-like parts, such as fixing methods such as pins and screws, and the first docking rod 21 can rotate relative to the first mounting frame 101, that is, the first docking rod 21 can rotate with the first screw rod 31. When the first screw 31 rotates, the relative position relationship between the two will not change, that is, when fixed by screws and pins, the position relationship between the corresponding holes on the first screw rod 31 and the first docking rod 21 will not change, which is convenient for connection.

[0085] In order to enable the first docking rod 21 to rotate following the first screw rod 31, in some embodiments, it can be achieved in the form of a square hole and a square shaft. In some embodiments, please refer to Figure 6 and Figure 7 The first docking and the first screw rod 31 can be achieved through a protrusion and a groove extending in the up-down direction.

[0086] The present design does not limit the specific detachable connection mode between the first docking rod 21 and the first screw rod 31 , which may be in the form of a screw and a threaded hole, or in the form of a pin and a pin hole.

[0087] It is understandable that if the first screw rod 31 is directly rotated, the second mounting bracket 102 may rotate with it. During the rotation, the installer may hold the second mounting bracket 102 by hand, but a slight angle change will inevitably occur, affecting the installation. In order to limit the second mounting bracket 102 from rotating with the first screw rod 31, in the embodiment of the present application, please refer to Figure 3 The matching structure 3 also includes a first limiting rod 32, which is slidably installed on the second mounting frame 102 along the up and down directions, and the first limiting rod 32 is supported by the docking structure 2; in this way, the first limiting rod 32 is provided with a supporting force by the docking structure 2, so that the first limiting rod 32 can remain stable. Therefore, when the first screw rod 31 rotates, the second mounting frame 102 will be restricted by the first limiting rod 32, so that the second mounting frame 102 will not rotate without hand support, but will move upward or downward.

[0088] In order to improve the stability of the installation of the second mounting frame 102 and the first mounting frame 101, in some embodiments, the docking structure 2 also includes a second docking rod 22 arranged on the first mounting frame 101, and the second docking rod 22 is detachably connected to the first limiting rod 32. After the adjustment is completed, the second docking rod 22 and the first limiting rod 32 can be fixed to avoid instability caused by the first mounting frame 101 and the second mounting frame 102 being supported only by the first screw rod 31 and the first docking rod 21 bracket.

[0089] The present design does not limit the detachable connection method between the first limiting rod 32 and the second docking rod 22, which can be in the form of a screw and a threaded hole, or in the form of a pin and a pin hole.

[0090] Since the first limiting rod 32 is arranged to slide in the up and down direction relative to the second mounting frame 102, there is a risk that the first limiting rod 32 slides and separates from the second mounting frame 102 during actual use. In order to prevent the first limiting rod 32 from being separated from the mounting frame 1, in some embodiments, a protrusion can be provided on the first limiting rod 32, and the protrusion can prevent the first limiting rod 32 from passing through the corresponding hole on the second mounting frame 102. In the embodiment of the present application, the matching structure 3 also includes a connecting piece 33 with one end rotatably connected to the first screw rod 31 and the other end fixedly connected to the first limiting rod 32. The setting of 33 connects the first screw rod 31 and the first limiting rod 32. When the first screw rod 31 does not rotate, the first limiting rod 32 will not slide relative to the second mounting frame 102. When the first screw rod 31 rotates, the first limiting rod 32 can be driven to rise or fall synchronously through the connecting piece 33, which will not affect the installation. Compared with setting a protrusion on the first limiting rod 32, although the first limiting rod 32 will not be separated from the second mounting frame 102, since the first limiting rod 32 needs to slide, the first limiting rod 32 still has a free moving position, which is prone to collision and damage during actual installation.

[0091] It should be noted that when the number of mounting brackets 1 is greater than two, for example, Figures 1 to 5 The third mounting frame 103 is also shown. When the third mounting frame 103 is stacked up and down with other mounting frames 1, it is located above the second mounting frame 102. Then, the second mounting frame 102 will be provided with a corresponding docking structure 2, and the third mounting frame 103 will be provided with a matching structure 3 to match the docking structure 2. If the width of the mounting frame 1 itself is very small, please refer to Figure 3 The docking structure 2 on the second mounting frame 102 can be set above the connecting piece 33 of its own matching structure 3. If the width of the mounting frame 1 itself is sufficient, the docking structure 2 on the second mounting frame 102 can also be directly set on the upper side of the second mounting frame 102.

[0092] For some display devices 200 with a larger size, after being installed on the mounting frame 1, if there is only one supporting point, that is, there is only one mounting portion 11, the installation may be unstable or the mounting portion 11 may be easily damaged. Figure 4The mounting frame 1 includes a main body 12 and two extensions 13. The main body 12 extends in the longitudinal direction. The two extensions 13 are respectively arranged at both ends of the main body 12 in the longitudinal direction. There are multiple mounting parts 11, and at least two of them are arranged on the two extensions 13, and at least one is arranged on the main body 12. In this way, when the size of the display device 200 is small, it can be installed only by the mounting parts 11 on the main body 12. When the size is large, the display device 200 is supported by two or even more mounting parts 11 on the two extensions 13, and the installation is more stable.

[0093] In order to enable the mounting frame 1 to adapt to more display devices 200 of different sizes, in an embodiment of the present application, the extension portion 13 can be slidably arranged in the longitudinal direction relative to the main body portion 12. In this way, the distance between the two mounting portions 11 on the two extension portions 13 can be changed, and different installation positions of different display devices 200 can be adapted, thereby having a wider practical range.

[0094] When the minimum spacing between the two mounting portions 11 on the two extension portions 13 is also larger than the size of the display device 200 to be installed, it is installed through the mounting portion 11 on the main body 12. However, at this time, the two extension portions 13 will obviously cause the mounting frame 1 to be longer than the display device 200, which will cause the mounting frame 1 to protrude from the display device 200, which is not aesthetically pleasing. Therefore, in an embodiment of the present application, the extension portion 13 is rotatable relative to the main body 12 along an axis extending in the up-down direction. With this arrangement, when the display device 200 does not need to be installed through the mounting portion 11 on the extension portion 13, the extension portion 13 can be rotated to the rear of the display device 200, and it can be shielded by the display device 200, thereby improving the aesthetics of the overall structural appearance.

[0095] The extension part 13 can slide and rotate relative to the main body 12 at the same time. It only needs to set a sliding rod between the extension part 13 and the main body 12, and slide with the main body 12 through the sliding rod. Then, the extension part 13 is rotatably connected with the sliding rod to realize rotation and sliding at the same time.

[0096] The present invention also provides a display device, which includes multiple display devices 200 and a combined bracket 100. The specific structure of the combined bracket 100 refers to the above embodiment. Since the display device adopts all the technical solutions of all the above embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be described one by one here. Among them, the multiple display devices 200 are correspondingly installed on the mounting parts 11 of the multiple mounting frames 1.

[0097] There are many ways to install the display device 200 and the installation part 11, which can be directly connected by screws. In the embodiment of the present application, in order to facilitate the installation of the display device 200, please refer to Figure 2 and Figure 5 The mounting portion 11 includes an upwardly disposed support plate 111, and a cover shell 201 with an opening facing downward is disposed on the display device 200, and the cover shell 201 is mounted on the support plate 111; thus, during installation, the cover shell 201 can be directly mounted on the support from top to bottom, and the installation is convenient. Since the support plate 111 is upwardly disposed, the cover shell 201 is not easily separated from the support plate 111 under the action of gravity. During disassembly, the display device 200 can be directly lifted upward.

[0098] In order to further improve the stability of the display device 200, in some embodiments, please refer to Figure 2 , Figure 5 and Figure 7 Slide protrusions and slide grooves extending in the up-down direction are respectively arranged on the casing 201 and the support plate 111. The casing 201 and the support plate 111 can be limited in multiple directions by the arrangement of the slide protrusions and the slide grooves, thereby improving stability.

[0099] The method of improving stability is not limited to this. The combined bracket 100 also includes a locking structure, which includes a locking portion and a locking matching portion respectively arranged on the support plate 111 and the casing 201. The locking portion can move in a direction close to and away from the locking matching portion to have a locking position and an unlocking position; in the locking position, the locking portion and the locking matching portion are locked and matched to lock the casing 201 and the support plate 111; in the unlocking position, the locking portion and the locking matching portion are separated. In this way, the arrangement of the locking portion and the locking matching portion can further improve the stability of the connection between the support plate 111 and the casing 201.

[0100] It is understandable that the setting of the locking structure will affect the convenience of installation and disassembly of the display device 200 to a certain extent. During installation and disassembly, the locking part needs to be manually operated to move in a direction away from the locking matching part. In order to improve the convenience of assembly and disassembly, the locking part is elastically connected by an elastic member, and an inclined surface or arc is provided at one end of the locking part facing the locking matching part. In this way, during installation, the sleeve shell 201 is sleeved on the support plate 111, and the locking part can be directly moved to separate from the locking matching part under the action of gravity. After the installation is completed, the sleeve shell is reset under the action of the elastic member and cooperates with the locking matching part. During disassembly, it is only necessary to overcome the elastic force of the elastic member, and both installation and disassembly are relatively convenient.

[0101] The above description is only an exemplary embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the technical concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
