Description

Technical Field

[0001] The utility model relates to the technical field of brackets, in particular to a display bracket. Background Art

[0002] Monitors are graphic display tools that people often use in their daily lives and work. Monitors are often mounted on stands so that the position of the monitor can be adjusted relative to the person viewing the screen. Monitors can be moved both angularly and vertically. Monitors are typically able to move around at least one (and possibly two) vertical axes as well as around an overall horizontal axis.

[0003] Currently, there are two types of commonly used monitor stands: one is an integrated monitor stand, and the other is a detachable monitor stand. The integrated monitor stand provides stable support for the monitor during use, but has the disadvantage that it cannot be disassembled and installed, occupies a large space during transportation, and has a high transportation cost.

[0004] Although the detachable monitor stand can be disassembled, in order to facilitate the disassembly and assembly of the monitor stand, the assembly of the monitor stand is usually completed by the cooperation of the monitor stand components through the insertion of the plug rod and the plug tube. Although this makes the disassembly and assembly of the monitor stand simple and convenient, the monitor stand component farthest from the end where the monitor is installed is subjected to the greatest gravity vertical to the ground when supporting the monitor. Since the commonly used monitor stands have a certain angle with the ground, the gravity of the monitor on the monitor stand components is divided into two forces, one vertical to the ground and the other in the direction of the tilt of the monitor stand. At this time, the reduction of the gravity on the monitor stand components will make the connection between the monitor stand components less stable. If the monitor installed on the monitor stand shakes up and down, the monitor stand components are likely to separate, which will lead to a safety hazard of damaging the monitor connected to the monitor stand.

[0005] Therefore, those skilled in the art provide a display stand to solve the problems raised in the above background technology. Utility Model Content

[0023] The limiting assembly includes a limiting groove 7 provided in the first plug-in tube 5 and a groove 8 provided on the first plug-in rod 3. A limiting plate 9 is rotatably provided in the limiting groove 7 through a connecting seat. A limiting block 10 is fixedly provided on the limiting plate 9. The limiting block 10 corresponds to the groove 8 on the first plug-in rod 3, and the limiting block 10 is clamped in the groove 8 on the first plug-in rod 3. An extrusion spring 11 is fixedly provided in the limiting groove 7. One end of the extrusion spring 11 is fixedly connected to the limiting plate 9, and the position of the extrusion spring 11 corresponds to the limiting block 10 above the first plug-in rod 3. A limiting opening 12 is provided in the limiting plate 9, and a sliding rod 13 is slidably provided on the limiting opening 12. A push rod 14 is fixedly provided on the sliding rod 13, and the end of the push rod 14 away from the sliding rod 13 passes through the first plug-in tube 5.

[0024] In this embodiment, when the first connecting arm 4 is connected to the fixing seat 2, the first plug-in tube 5 at one end of the first connecting arm 4 is first sleeved on the first plug-in rod 3 on the fixing seat 2, and then the first plug-in tube 5 is pushed forward. When the limit block 10 in the first plug-in tube 5 contacts the first plug-in rod 3, the limit block 10 is forced to be squeezed in the limit groove 7. During the squeezing process, the limit block 10 squeezes the spring 11 to contract. Then, the first plug-in tube 5 is pushed downward continuously. When the limit block 10 and the groove 8 on the first plug-in rod 3 are at the same level, When the first connecting arm 4 and the fixed seat 2 need to be separated, the push rod 14 is pressed toward the first insertion tube 5. The pressing of the push rod 14 drives the limit plate 9 to rotate in the limit groove 7. The rotation of the limit plate 9 will pop out the limit block 10 in the groove 8, and then the first connecting arm 4 is pulled upward to complete the separation of the first connecting arm 4 and the fixed seat 2.

[0025] By setting the limiting component, the connection between the first connecting arm 4 and the fixing base 2 can be made more stable, thereby reducing the separation of the first connecting arm 4 and the fixing base 2 due to the shaking of the display connection component, thereby reducing the cases where the display connected to the display connection component falls to the ground and is damaged, and further effectively improving the safety of display use.

[0026] The first connecting arm 4 is rotatably connected to a rotating wheel 15, an outer wall surface of the rotating wheel 15 is provided with an engaging protrusion 16, the mounting rod 6 is provided with a guide groove 17, the rotating wheel 15 is inserted into the guide groove 17, an engaging groove 18 is provided in the guide groove 17, the engaging protrusion 16 on the rotating wheel 15 and the engaging groove 18 in the guide groove 17 are meshed with each other, and the engaging protrusion 16 rotates.

[0027] In this embodiment, when the arm length of the first connecting arm 4 needs to be adjusted, the rotary wheel 15 is rotated, and the rotation of the rotary wheel 15 drives the bite protrusion 16 on the outer wall of the rotary wheel 15 to rotate. The rotation of the bite protrusion 16 will drive the installation rod 6 to move along the inner wall of the first connecting arm 4 through the engagement with the bite groove 18. The movement of the installation rod 6 drives the display connection assembly to move. When the display connection assembly moves to a suitable position, the rotation of the rotary wheel 15 is stopped. The display connection frame 22 is provided with a positioning hole, and the diameter of the second insertion rod 19 is adapted to the inner diameter of the second insertion tube 20. The positioning hole is provided to facilitate the installation of the display on the display connection frame 22.

[0028] By cooperating with the rotating wheel 15, the engaging protrusion 16 and the engaging groove 18, the extending length of the mounting rod 6 on the first connecting arm 4 can be adjusted, so that the arm length of the first connecting arm 4 can be adjusted. The adjustable arm length of the first connecting arm 4 allows the display connected to the display connecting assembly to be adjusted in lateral position, which makes the installation of the lateral position of the display more flexible.

[0029] The display connection assembly includes a second plug rod 19 fixedly mounted on the mounting rod 6 and a second plug tube 20 sleeved on the second plug rod 19 , a connecting rod 21 is fixedly mounted on the second plug tube 20 , and a display connection frame 22 is fixedly mounted on one end of the connecting rod 21 away from the second plug tube 20 .

[0030] The working principle of the utility model is:

[0031] When the first connecting arm 4 is connected to the fixed seat 2, the first plug tube 5 at one end of the first connecting arm 4 is first sleeved on the first plug rod 3 on the fixed seat 2, and then the first plug tube 5 is pushed forward. When the limit block 10 in the first plug tube 5 contacts the first plug rod 3, the limit block 10 is squeezed into the limit groove 7. During the squeezing process, the limit block 10 squeezes the spring 11 to shrink, and then continues to push the first plug tube 5 downward. When the limit block 10 and the groove 8 on the first plug rod 3 are at the same horizontal line, the squeezing spring 11 pushes the limit block 10 into the groove 8 on the first plug rod 3 through its own elastic characteristics. At this time, the connection between the first connecting arm 4 and the fixed seat 2 is completed. When the first connecting arm 4 needs to be connected to the fixed seat When the fixed seat 2 is to be disassembled, the push rod 14 is pressed toward the first inserting tube 5, and the pressing of the push rod 14 drives the limit plate 9 to rotate in the limit groove 7. The rotation of the limit plate 9 will pop out the limit block 10 in the groove 8, and then the first connecting arm 4 is pulled upward, and the first connecting arm 4 and the fixed seat 2 can be separated; when the arm length of the first connecting arm 4 needs to be adjusted, the rotating wheel 15 is rotated, and the rotation of the rotating wheel 15 drives the bite protrusion 16 on the outer wall of the rotating wheel 15 to rotate, and the rotation of the bite protrusion 16 will drive the installation rod 6 to move along the inner wall of the first connecting arm 4 through the engagement with the bite groove 18, and the movement of the installation rod 6 drives the display connection assembly to move, and the rotation of the rotating wheel 15 is stopped when the display connection assembly moves to a suitable position.
