[0031] Reference below Figures 1 to 5 A display screen installation device according to an embodiment of the present utility model is described in detail.

[0032] refer to Figures 1 to 3According to some embodiments of the present invention, the display screen mounting device includes a display screen mounting frame 10, a quick-release mounting plate 100, and a bracket 20. The display screen mounting frame 10 is used to mount the display screen. The quick-release mounting plate 100 is detachably connected to the display screen mounting frame 10. The quick-release mounting plate 100 is provided with a mounting groove 110. The side wall of the mounting groove 110 is provided with a first clamping hole 120. The bracket 20 includes a quick-release module 200. The quick-release module 200 is arranged in the mounting groove 110. The quick-release module 200 includes a clamping member 210 and a locking structure 220. A first clamping protrusion 211 is provided on the connecting member 210, and the first clamping protrusion 211 is passed through the first clamping hole 120; the locking structure 220 is connected to the clamping member 210 and can switch between a locked state and an unlocked state; wherein, when the locking structure 220 is in the locked state, it can cooperate with the groove wall of the installation groove 110 to lock the clamping member 210; when the locking structure 220 is in the unlocked state, it can be disengaged from the groove wall of the installation groove 110 and release the lock on the clamping member 210, so that the first clamping protrusion 211 can exit the first clamping hole 120.

[0033] In the display screen mounting device of this embodiment, when installing the display screen mounting frame 10 and the bracket 20, the user can install the quick-release mounting plate 100 on the display screen mounting frame 10. Then, the user can accommodate the quick-release module 200 of the bracket 20 in the mounting groove 110 of the quick-release mounting plate 100, and make the first engaging protrusion 211 of the engaging member 210 of the quick-release module 200 pass through the first engaging hole 120 of the side wall of the mounting groove 110. Then, the user can switch the locking structure 220 to the locking state so that the locking structure 220 can cooperate with the groove wall of the mounting groove 110 to lock the engaging member 210. , thereby realizing the connection between the bracket 20 and the quick-release mounting plate 100, and then realizing the installation between the display screen mounting frame 10 and the bracket 20; when realizing the disassembly between the display screen mounting frame 10 and the bracket 20, the user can switch the locking structure 220 to the unlocked state. At this time, the clamping member 210 is in a movable state, and the user can remove the quick-release module 200 from the mounting groove 110 and make the first clamping protrusion 211 of the clamping member 210 disengage from the first clamping hole 120 to realize the disassembly between the bracket 20 and the quick-release mounting plate 100, thereby realizing the disassembly between the display screen mounting frame 10 and the bracket 20.

[0034] It can be understood that the user can achieve the connection or disassembly between the display screen mounting frame 10 and the bracket 20 by achieving the connection or disassembly between the bracket 20 and the quick-release mounting plate 100. Since the quick-release mounting plate 100 will bear the wear caused by the installation and disassembly of the bracket 20 during the frequent installation and disassembly, the wear of the display screen mounting frame 10 caused by the bracket 20 during the installation and disassembly process is reduced, thereby protecting the display screen mounting frame 10. At the same time, since the quick-release mounting plate 100 is detachably connected to the display screen mounting frame 10, when the quick-release mounting plate 100 is severely worn, the user can directly replace the quick-release mounting plate 100.

[0035] It can be understood that after the quick-release module 200 of the bracket 20 is inserted into the mounting groove 110 of the quick-release mounting plate 100, the user can achieve the connection or disassembly between the bracket 20 and the quick-release mounting plate 100 by switching the locking structure 220 between the locked state and the unlocked state, thereby achieving the connection or disassembly between the bracket 20 and the display mounting frame 10, and the connection and disassembly between the bracket 20 and the display mounting frame 10 is simpler and more convenient.

[0036] In some embodiments of the present invention, the locking structure 220 includes a locking member 221, a second clamping protrusion 221a is provided on the locking member 221, and a second clamping hole 130 is provided on the side wall of the installation groove 110, and the second clamping hole 130 and the first clamping hole 120 are respectively located on two opposite side walls of the installation groove 110; the locking member 221 is slidably provided on the clamping member 210, and the locking structure 220 can be switched between a locked state and an unlocked state by sliding the locking member 221; when the locking structure 220 is in the locked state, the second clamping protrusion 221a is passed through the second clamping hole 130; when the locking structure 220 is in the unlocked state, the second clamping protrusion 221a is disengaged from the second clamping hole 130, and the first clamping protrusion 211 can be allowed to exit the first clamping hole 120. For example, Figure 2 、 Figure 3 and Figure 5 As shown, the locking structure 220 is provided at the lower end of the clamping member 210, and the upper end of the clamping member 210 is provided with a first clamping protrusion 211. The locking structure 220 includes a locking member 221, and the locking member 221 is slidably provided on the clamping member 210 along the vertical direction. The lower end of the locking member 221 is provided with a second clamping protrusion 221a, and the upper side groove wall of the installation groove 110 is provided with a first clamping hole 120, and the lower side groove wall of the installation groove 110 is provided with a second clamping hole 130.

[0037] When the locking member 221 slides downward relative to the clamping member 210 so that the second clamping protrusion 221a on the locking member 221 is inserted into the second clamping hole 130, the locking structure 220 is in a locked state. The locking member 221 can prevent the clamping member 210 from continuing to slide downward in the mounting groove 110, thereby allowing the first clamping protrusion 211 to be stably inserted into the first clamping hole 120 to achieve the connection between the bracket 20 and the quick-release mounting plate 100; when the locking member 221 slides upward relative to the clamping member 210 so that the second clamping protrusion 221a on the locking member 221 is disengaged from the second clamping hole 130, the locking structure 220 is in an unlocked state, and the clamping member 210 can move downward in the mounting groove 110 so that the first clamping protrusion 211 is disengaged from the first clamping hole 120 to achieve the disassembly between the bracket 20 and the quick-release mounting plate 100. Therefore, the user can connect or disassemble the bracket 20 and the quick-release mounting plate 100 by sliding the locking member 221 relative to the snap-fit ​​member 210 so that the second snap-fit ​​protrusion 221a on the locking member 221 is inserted into or disengaged from the second snap-fit ​​hole 130; the assembly and disassembly process between the bracket 20 and the quick-release mounting plate 100 is more convenient and quick.

[0038] In some embodiments, the locking structure 220 further includes an elastic member 222, which is connected to the clamping member 210 and the locking member 221, respectively. The elastic member 222 is used to provide an elastic force to keep the second clamping protrusion 221a inserted into the second clamping hole 130. Figure 4 and Figure 5 As shown, the locking structure 220 also includes an elastic member 222, the upper and lower ends of the elastic member 222 are respectively connected to the clamping member 210 and the locking member 221, and the elastic member 222 can provide a downward elastic force to the locking member 221 so that the second clamping protrusion 221a on the locking member 221 can remain inserted into the second clamping hole 130.

[0039] It can be understood that the locking member 221 can, under the elastic force of the elastic member 222, enable the second clamping protrusion 221a of the locking member 221 to remain inserted into the second clamping hole 130, so that the locking structure 220 can remain in a locked state under normal circumstances, so that a stable connection can be maintained between the bracket 20 and the quick-release mounting plate 100; when the user needs to disconnect the bracket 20 and the quick-release mounting plate 100, the user can overcome the elastic force of the elastic member 222 to push the locking member 221 upward, so that the second clamping protrusion 221a of the locking member 221 disengages from the second clamping hole 130, thereby switching the locking structure 220 from the locked state to the unlocked state.

[0040] In some embodiments of the present invention, the elastic member 222 is a spring, and a positioning groove 221b is provided on the locking member 221. One end of the spring is passed through the positioning groove 221b and connected to the groove wall of the positioning groove 221b. Figure 4 As shown, the locking member 221 is provided with a positioning groove 221b extending in the vertical direction, the upper end of the spring is connected to the clamping member 210, and the lower end of the spring is passed through the positioning groove 221b and connected to the bottom of the positioning groove 221b.

[0041] It is understandable that by providing a positioning groove 221b on the locking member 221 and having one end of the spring pass through the positioning groove 221b, the groove wall of the positioning groove 221b can position the spring to reduce deformation of the spring in the horizontal direction.

[0042] In some embodiments of the present invention, a first positioning protrusion 212 is provided on the clamping member 210, a second positioning protrusion 221c is provided in the positioning groove 221b, and opposite ends of the spring are respectively sleeved on the first positioning protrusion 212 and the second positioning protrusion 221c. Figure 4 and Figure 5 As shown, a vertically extending first positioning protrusion 212 is provided on the clamping member 210, a vertically extending second positioning protrusion 221c is provided in the positioning groove 221b, the upper end of the spring is sleeved on the first positioning protrusion 212, and the lower end of the spring is sleeved on the second positioning protrusion 221c.

[0043] It can be understood that the setting of the first positioning protrusion 212 enables the first positioning protrusion 212 to position the upper end of the spring in the horizontal direction, and the setting of the second positioning protrusion 221c enables the second positioning protrusion 221c to position the lower end of the spring in the horizontal direction; under the cooperation of the first positioning protrusion 212 and the second positioning protrusion 221c, the spring can be accurately compressed or extended in the vertical direction, and during the compression or extension process of the spring, the deformation of the spring itself in the horizontal direction can be smaller.

[0044] In some embodiments of the present invention, the locking member 221 is provided with a plurality of elongated holes 221d, the extension direction of the elongated holes 221d is the sliding direction of the locking member 221, and the quick-release module 200 further includes a threaded connector, the rod of which can be slidably passed through the elongated holes 221d, and the threaded connector is threadedly connected to the clamping member 210. For example, Figure 3As shown, four long holes 221d distributed along the left and right directions are provided on the locking member 221, and the long holes 221d are extended in the vertical direction. The quick-release module 200 also includes four threaded connectors, and the threaded connectors and the long holes 221d are arranged one by one. Between the corresponding threaded connectors and the long holes 221d, the rod of the threaded connector can be slidably passed through the long holes 221d, and the threaded connector is threadedly connected to the clamping member 210.

[0045] It can be understood that by setting the elongated hole 221d and the rod of the threaded connector being slidably inserted into the elongated hole 221d, when the locking structure 220 switches between the locked state and the unlocked state, the locking member 221 can accurately slide in the vertical direction with the cooperation of the threaded connector and the elongated hole 221d, so that the second clamping protrusion 221a on the locking member 221 can accurately pass through or disengage from the second clamping hole 130.

[0046] In some embodiments of the present invention, the locking member 221 is provided with a protrusion 221e, and the clamping member 210 is provided with a slide groove 213. The extension direction of the slide groove 213 is the sliding direction of the locking member 221, and the protrusion 221e can be slidably passed through the slide groove 213. Figure 5 As shown, the locking member 221 is provided with two protrusions 221e distributed along the left and right directions, and the clamping member 210 is correspondingly provided with two sliding grooves 213 distributed along the left and right directions. The sliding grooves 213 are extended in the vertical direction, and the two protrusions 221e are respectively inserted into the two sliding grooves 213, and the protrusions 221e can be slidably set in the sliding grooves 213 along the vertical direction.

[0047] It can be understood that by providing the protrusion 221e and the slide groove 213, and the protrusion 221e can be slidably arranged in the slide groove 213 along the vertical direction, the protrusion 221e can slide accurately along the vertical direction with the locking member 221 under the limiting action of the groove wall of the slide groove 213, so that the second clamping protrusion 221a on the locking member 221 can be accurately inserted into or disengaged from the second clamping hole 130.

[0048] refer to Figure 2 and Figure 3 In some embodiments of the present invention, the locking member 221 is provided with a push button 221f for receiving a push force applied by the user. It is understood that the user can push the push button 221f to cause the locking member 221 to slide relative to the engaging member 210. The provision of the push button 221f allows the user to more conveniently drive the locking member 221 to slide relative to the engaging member 210.

[0049] In some embodiments of the present invention, the quick-release module 200 also includes a cover body 230, which is connected to the clip 210. The cover body 230 and the clip 210 jointly define an accommodating cavity. The locking structure 220 is arranged in the accommodating cavity. The cavity wall of the accommodating cavity is provided with an avoidance groove 231 and an avoidance hole 232. The push button 221f passes through the avoidance groove 231 and extends to the outside of the accommodating cavity. The second clip protrusion 221a passes through the avoidance hole 232 and extends to the outside of the accommodating cavity.

[0050] For example, Figure 2 As shown, the quick-release module 200 includes a cover body 230 and a snap-fit ​​member 210, the snap-fit ​​member 210 is connected to the front end of the cover body 230, and an accommodating cavity is formed between the snap-fit ​​member 210 and the cover body 230, and an avoidance groove 231 and an avoidance hole 232 are respectively provided on the rear cavity wall and the lower cavity wall of the accommodating cavity. The locking structure 220 is arranged in the accommodating cavity, and the push button 221f of the locking structure 220 passes through the avoidance groove 231 and extends backward to the outside of the accommodating cavity, and the second snap-fit ​​protrusion 221a passes through the avoidance hole 232 and extends downward to the outside of the accommodating cavity.

[0051] It can be understood that since a accommodating cavity is defined between the cover body 230 and the snap-connector 210, by arranging the locking structure 220 in the accommodating cavity, the cover body 230 and the snap-connector 210 can cooperate to protect the locking structure 220, so as to reduce the impact of the external environment on the locking structure 220, thereby extending the service life of the locking structure 220.

[0052] refer to Figure 3 In some embodiments of the present invention, a guide surface 211 a is provided on the first engaging protrusion 211 , and the guide surface 211 a is used to guide the first engaging protrusion 211 to pass through the first engaging hole 120 .

[0053] It can be understood that by providing a guide surface 211a on the first clamping protrusion 211, the guide surface 211a can guide the first clamping protrusion 211 during the process of the first clamping protrusion 211 passing through the first clamping hole 120, so that the first clamping protrusion 211 can be inserted into the first clamping hole 120 more smoothly.

[0054] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and purpose of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
