Description

TECHNICAL FIELD

[0001] The application relates to the technical field of display screen back cover mounting structures, in particular to a display screen back cover connecting structure. BACKGROUND

[0002] The display screen is a screen body composed of a plurality of display units that can be combined and spliced, and a proper controller, so that a plurality of display panels of various specifications can be combined with the controllers of different control technologies to form many kinds of LED display screens to meet the needs of different environments and different display requirements.

[0003] The display screen back cover is a tool for protecting the display screen and assisting in the installation of the display screen. The display screen back cover is a structure for installing the display screen on a predetermined frame through the display screen back cover. In the prior art, the display screen back cover is fixed on the predetermined frame through screws. However, when installing or dismounting some fixed screws, a technician needs to manually and laboriously support and fix the display screen back cover, the operation space is limited, the screw holes need to be accurately aligned, the whole display screen installation or dismounting process is relatively complicated and laborious, and thus the work efficiency is affected, and thus improvement is needed. CONTENT OF THE INVENTION

[0004] In order to conveniently install or dismount the display screen back cover on or from the frame, the application provides a display screen back cover connecting structure.

[0005] The display screen back cover connecting structure provided by the application adopts the following technical scheme:

[0006] The display screen back cover connecting structure comprises a back cover plate, a mounting shell, a clamping block, a driving handle and a connecting assembly. The mounting shell is detachably connected to one side of the back cover plate and forms an installation cavity with the back cover plate. The clamping block is slidably connected in the installation cavity. The driving handle is rotatably connected to the mounting shell and connected to the clamping block through the connecting assembly. The driving handle is used for controlling the linear movement of the clamping block.

[0007] When the display screen back cover needs to be installed or dismounted, the worker can manually control the rotation of the driving handle. Under the action of the connecting assembly, the rotation of the driving handle is converted into the linear movement of the clamping block, so that the clamping block extends out of the mounting shell and is inserted into the clamping groove of the external frame, and the pre-positioning of the back cover plate is completed by relying on the action of static friction. After pre-positioning, the worker can more easily install or dismount the fixed screws on other parts of the display screen back cover, thereby reducing the labor intensity of the worker.

[0008] Preferably, the connecting assembly comprises a first rack, a second rack, a rotating shaft and a gear, the first rack and the second rack are parallel to each other and are both slidably connected to the back cover plate; the clamping block is provided with at least two, and the two clamping blocks are respectively connected to the end of the first rack and the second rack.

[0009] The rotating shaft is rotatably connected to the mounting cavity, and the two ends are connected with the gear, and the two gears are engaged with the first rack and the second rack, and the driving handle is connected to the rotating shaft.

[0010] By adopting the above technical scheme, when the staff manually controls the rotation of the driving handle, the rotating shaft and the gear will rotate synchronously, and the rotation of the gear drives the first rack and the second rack to move linearly, thereby realizing the movement of the clamping block.

[0011] Preferably, a limiting groove is formed in the mounting shell, and the limiting groove is used for limiting the driving handle; when the driving handle is clamped in the limiting groove, the clamping block protrudes out of the mounting cavity.

[0012] By adopting the above technical scheme, when the driving handle is clamped in the limiting groove, the clamping block protrudes out of the mounting cavity, that is, the clamping block can be connected with the external frame at this time. Since the driving handle is clamped in the limiting groove, the driving handle cannot rotate spontaneously under the limiting action of the static friction without external force intervention, so the clamping block cannot move into the mounting cavity, thereby ensuring the positioning of the back cover plate.

[0013] Preferably, a friction layer is arranged on the inner wall of the limiting groove.

[0014] By adopting the above technical scheme, the friction layer has a large anti-skid coefficient, which can increase the static friction between the driving handle and the mounting shell and improve the stability of the driving handle in the limiting groove.

[0015] Preferably, a plug hole is formed in the side of the back cover plate away from the mounting shell, and the plug hole is communicated with the limiting groove.

[0016] By adopting the above technical scheme, when it is necessary to release the locking action of the clamping block and the external frame, one way is to control the rotation of the driving handle to move the clamping block, and the other way is to insert a needle-like small object into the plug hole to drive the driving handle to rotate, thereby completing the unlocking.

[0017] Preferably, support columns are arranged on the back cover plate in an interval, and each support column is on the same side of the mounting shell.

[0018] By adopting the above technical scheme, when it is necessary to place the entire back cover of the display screen, the side where the support columns are located can be placed on the horizontal plane to realize the support.

[0019] Preferably, the mounting shell is locked to the rear cover plate by fasteners, which are fastening bolts or fastening screws.

[0020] By adopting the above technical scheme, the fastening bolts or fastening screws are detachable objects, facilitating the replacement of the mounting shell.

[0021] Preferably, the rear cover plate is provided with through holes on both sides, and the through holes form handles.

[0022] By adopting the above technical scheme, the hands of the worker can be held on the handles, so that the rear cover plate can be better forced.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] (1) By setting the clamping block, the driving handle and the connecting assembly, when the rear cover of the display screen is installed or disassembled, the worker can manually operate the driving handle to rotate. Under the conduction of the connecting assembly, the rotary motion of the driving handle will be converted into the linear motion of the clamping block, prompting the clamping block to extend out of the mounting shell and accurately insert into the clamping groove of the external frame. At this time, with the help of the action of static friction, the preliminary positioning of the rear cover plate is realized.

[0025] (2) By setting the limiting groove, when the driving handle is clamped in the limiting groove, the clamping block extends out of the mounting cavity, that is, the clamping block can be connected with the external frame at this time, and the limiting groove can limit the rotation of the driving handle.

[0026] (3) By setting the supporting columns, the supporting columns can support the entire rear cover of the display screen, realizing the stable placement of the rear cover of the display screen. BRIEF DESCRIPTION OF DRAWINGS

[0035] In the following, some embodiments of the present application will be described in detail with reference to the drawings. Those skilled in the art can combine and combine the different embodiments or examples represented in the present application and the features of the different embodiments or examples without conflict.

[0036] The embodiments of the present application disclose a display screen back cover connecting structure for positioning the display screen on the frame. Referring to Figure 1 and Figure 2 , the display screen back cover includes a back cover plate 1, a mounting shell 2, a clamping block 3, a driving handle 4 and a connecting assembly 5. The back cover plate 1 serves as a support carrier and can be made of metal or hard plastic material. The mounting shell 2 is detachably connected to one side of the back cover plate 1, and an installation cavity is formed between the mounting shell 2 and the back cover plate 1. In the present embodiment, the mounting shell 2 is locked on the back cover plate 1 by fasteners, which are fastening bolts or fastening screws.

[0037] The clamping block 3 is slidably connected in the installation cavity, the driving handle 4 is rotatably connected on the installation shell 2 and connected with the clamping block 3 through the connecting assembly 5, and the driving handle 4 is used for controlling the linear movement of the clamping block 3. Specifically, the connecting assembly 5 comprises a first rack 51, a second rack 52, a rotating shaft 53 and a gear 54, the first rack 51 and the second rack 52 are both located in the installation cavity, the first rack 51 and the second rack 52 are parallel to each other and are slidably connected on the rear cover plate 1, and the sliding mode of the first rack 51 and the second rack 52 can adopt the sliding block and sliding groove cooperation.

[0038] The clamping block 3 is provided with two, one of which is fixedly connected to the end of the first rack 51, and the other is fixedly connected to the end of the second rack 52. The rotating shaft 53 is rotatably connected in the installation cavity, and the length direction of the rotating shaft 53 is perpendicular to the length direction of the first rack 51. The two ends of the rotating shaft 53 are fixedly connected with the gears 54, and the two gears 54 are engaged with the first rack 51 and the second rack 52 respectively. The driving handle 4 is fixedly connected on the rotating shaft 53, and the driving handle 4 is used for controlling the rotating shaft 53 to rotate along the axis direction of itself.

[0039] When it is necessary to install and dismount the rear cover of the display screen, the staff can manually control the driving handle 4 to rotate, so that the rotating shaft 53 and the gear 54 are synchronously followed to rotate, the rotation of the gear 54 drives the first rack 51 and the second rack 52 to move linearly, thereby realizing the movement of the clamping block 3. The clamping block 3 extends out of the installation shell 2 and is inserted into the clamping groove of the external frame, and the pre-positioning of the rear cover plate 1 is completed by relying on the action of static friction. After pre-positioning, the staff can more easily install or dismount the fixing screws of other parts on the rear cover of the display screen, thereby reducing the labor intensity of the staff.

[0040] The installation shell 2 is further provided with a limiting groove 6, and the limiting groove 6 is used for limiting the driving handle 4. When the driving handle 4 is clamped in the limiting groove 6, the clamping block 3 is just completely extended out of the installation cavity. When the driving handle 4 is clamped in the limiting groove 6, the clamping block 3 is just extended out of the installation cavity, that is, at this time, the clamping block 3 can be connected with the external frame. Since the driving handle 4 is clamped in the limiting groove 6, without external force intervention, the driving handle 4 cannot spontaneously rotate due to the limiting action of static friction, so the clamping block 3 will not move into the installation cavity, thereby ensuring the pre-positioning effect of the rear cover plate 1.

[0041] In some embodiments, a friction layer (not shown in the figure) is arranged on the inner wall of the limiting groove 6, and the friction layer is made of anti-skid material. The friction layer has a large anti-skid coefficient, which can increase the static friction force between the driving handle 4 and the installation shell 2 and improve the stability of the driving handle 4 in the limiting groove 6.

[0042] In combination Figure 3In some embodiments, the rear cover plate 1 is provided with a plug hole 7 on the side away from the mounting shell 2, and the plug hole 7 is communicated with the limiting groove 6. When it is needed to release the locking effect of the clamping block 3 and the external frame, one way is to control the rotation of the driving handle 4 to move the clamping block 3, and the other way is that a needle-like small object can be inserted into the plug hole 7 to top the driving handle 4 to rotate, thereby completing the unlocking.

[0043] In addition, the rear cover plate 1 is provided with support columns 8 at intervals, as shown, the number of the support columns 8 is four, each support column 8 is on the same side of the mounting shell 2 and is enclosed into a rectangular shape, and each support column 8 is used to support the rear cover plate 1 so that the entire display screen rear cover is placed on a horizontal plane. The rear cover plate 1 is provided with through holes 9 on both sides and forms handles, and the through holes 9 are used for the fingers of the workers to pass through. The hands of the workers can be gripped on the handles, so that the rear cover plate 1 is better forced.

[0044] The implementation principle of the display screen rear cover connecting structure of the embodiment of the application is that when the display screen rear cover is installed or disassembled, the worker can manually operate the driving handle 4 to rotate. Under the conduction of the connecting assembly 5, the rotary motion of the driving handle 4 is converted into the linear motion of the clamping block 3, so that the clamping block 3 is stretched out from the mounting shell 2 and is accurately inserted into the clamping groove of the external frame. At this time, the preliminary positioning of the rear cover plate 1 is realized by the action of the static friction. After the preliminary positioning, the worker can more easily install or disassemble the fixed screws of other parts of the display screen rear cover, thereby realizing the reduction of the labor intensity of the personnel.

[0045] The above are the preferred embodiments of the application, and do not limit the protection scope of the application, so that: all equivalent changes made according to the structure, shape, principle of the application should be covered in the protection scope of the application.
