Description

Technical Field

[0001] The present application relates to display installation technology, and in particular to a display control cabinet. Background Art

[0002] The existing display and control cabinet system generally includes multiple displays, and each display needs to work at the same time. There are usually two ways to install multiple displays on the cabinet. The first way is to install multiple displays on the columns in front of the cabinet in sequence. This installation takes up a lot of space for the plug-in box installation on the cabinet column, resulting in low cabinet space utilization; and multiple displays are located at different installation heights, and the observer needs to constantly look up and down to switch to observe all displays, which is easy to fatigue for the observer and has poor comfort for long-term use. The second installation method is to use a wall mount bracket to fix the display on the outer wall of the left and right side doors of the cabinet, and the display is unfolded and folded through the movement of the wall mount bracket. This also increases the space occupied by the cabinet, and the display installed outside the side door is easy to be bumped and damaged without the protection of the cabinet frame when carried at a close distance. Moreover, the wall mount bracket easily causes the display to be too far away from the cabinet column (that is, too close to the cabinet operation seat), which also affects the operating comfort. Summary of the invention

[0003] In order to solve one of the above-mentioned technical defects, a display and control cabinet is provided in an embodiment of the present application.

[0004] According to a first aspect of an embodiment of the present application, a display control cabinet is provided, comprising:

[0005] The cabinet body has a storage space for storing the display; a sliding mechanism is provided in the cabinet body;

[0006] The support plate is connected to the sliding mechanism; the support plate can be moved through the sliding mechanism to extend out of the storage space or move in the opposite direction to be stored in the storage space;

[0007] A display mounting bracket is arranged on the support plate for mounting the display; the display mounting bracket comprises:

[0008] A central shaft, the bottom of which is fixed on the support plate;

[0009] At least one rotating rod has one end rotatably connected to the top of the central shaft and the other end used for connecting to the display.

[0010] The technical solution provided by the embodiment of the present application is that a storage space for storing a display is provided in the cabinet body, and a sliding mechanism is provided in the cabinet body; a pallet is connected to the sliding mechanism, and is moved to extend out of the storage space or moved in the opposite direction to be stored in the storage space through the sliding mechanism; a display mounting bracket is provided on the pallet for mounting the display, and the display mounting bracket includes a central axis and at least one rotating rod, the bottom of the central axis is fixed to the pallet, and the top is rotatably connected to one end of the rotating rod, and the other end of the rotating rod is connected to the display, so that the pallet can be pulled out or retracted relative to the cabinet body, and the display can be horizontally rotated relative to the pallet through the rotating rod. Pulling out the pallet, rotating the display to the unfolded state, and then retracting the pallet is convenient for saving space and convenient for observing the display; after use, the pallet is pulled out, the display is rotated to the storage state, and then the whole is retracted into the cabinet body to store and protect the display, thereby reducing the overall size of the cabinet and making it more convenient to move and carry.

[0028] In order to make the technical solutions and advantages in the embodiments of the present application more clearly understood, the exemplary embodiments of the present application are further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present application, rather than an exhaustive list of all the embodiments. It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict.

[0029] The present embodiment provides a display control cabinet for installing a display, and enables the display to be unfolded and folded. When unfolded, it is convenient for observers to observe, and when folded, it does not occupy too much space.

[0030] like Figures 1 to 3 As shown, the display control cabinet provided in this embodiment includes: a cabinet body 1, a support plate 2 and a display mounting bracket 3. The cabinet body 1 is a cabinet structure, having a storage space for storing a display, and the display is located in the storage space when folded.

[0031] A sliding mechanism 4 is provided in the cabinet body 1, and the support plate 2 is connected to the sliding mechanism 4 and moves relative to the cabinet body 1 through the sliding mechanism. The support plate 2 can move outward to extend from the storage space, and can also move inward to be stored in the storage space.

[0032] The display mounting bracket 3 is arranged on the support plate 2 and is used to mount the display 5. The display mounting bracket 3 includes: a central axis 31 and at least one rotating rod 32. The central axis extends vertically, and its bottom is fixed to the upper surface of the support plate 2. One end of the rotating rod 32 is rotatably connected to the top of the central axis, and the other end is connected to the display 5, and the display 5 rotates together with the rotating rod 32.

[0033] In the storage state, the rotating rod 32 rotates relative to the central axis to the folded state, so that the sliding directions of the display 5 and the support plate 2 are substantially parallel. The display 5 and the support plate 2 are both stored in the cabinet body 1. Figure 2 shown.

[0034] During use, the support plate 2 is pulled out of the cabinet body 1, and then the rotating rod 32 is rotated outward horizontally until the display 5 is unfolded. At this time, the display 5 is roughly perpendicular to the sliding direction of the support plate 2. Then the support plate 2 is pushed back into the cabinet body 1, and the display also retreats to a position close to the cabinet body 1, so as not to occupy too much space. Figure 3 To clearly show the position of the display mounting bracket 3, Figure 3 The display 5 is omitted.

[0035] After use, the support plate 2 is pulled out of the cabinet body 1, and then the rotating rod 32 is horizontally rotated inward until the sliding direction of the display 5 is roughly parallel to the support plate 2, and then the support plate 2 is pushed back into the cabinet body 1 to put the display in the storage state.

[0036] The technical solution provided by this embodiment is that a storage space for storing a display is provided in the cabinet body, and a sliding mechanism is provided in the cabinet body; a pallet is connected to the sliding mechanism, and is moved to extend out of the storage space or moved in the opposite direction to be stored in the storage space through the sliding mechanism; a display mounting bracket is provided on the pallet for mounting the display, and the display mounting bracket includes a central axis and at least one rotating rod, the bottom of the central axis is fixed to the pallet, and the top is rotatably connected to one end of the rotating rod, and the other end of the rotating rod is connected to the display, so that the pallet can be pulled out or retracted relative to the cabinet body, and the display can be horizontally rotated relative to the pallet through the rotating rod. Pulling out the pallet, rotating the display to the unfolded state, and then retracting the pallet is convenient for saving space and convenient for observing the display; after use, the pallet is pulled out, the display is rotated to the storage state, and then the whole is retracted into the cabinet body to store and protect the display, thereby reducing the overall size of the cabinet and making it more convenient to move and carry.

[0037] On the basis of the above technical solution, this embodiment provides an implementation method of a cabinet body 1, such as Figure 1 As shown, the cabinet body 1 includes: a bottom plate 11, a top plate 12, two side plates 13 and four columns 16. The bottom plate 11 and the top plate 12 are parallel and arranged up and down, and the two side plates 13 are parallel and arranged oppositely and are respectively connected between the bottom plate 11 and the top plate 12. The bottom plate 11, the top plate 12, the two side plates 13, and the four columns 16 enclose a receiving space, which is open front and back.

[0038] A specific solution is as follows: four columns are respectively arranged between the bottom plate 11 and the top plate 12 and located at the four top corners of the top plate 12, and the side plate is located between two columns.

[0039] Further, a running wheel 14 may be provided below the cabinet body 1 to facilitate the movement of the cabinet body 1. The number of the running wheels 14 may be four, which are respectively provided at the four vertex corners of the lower surface of the bottom plate 11. At least two of the running wheels 14 are provided with a locking mechanism for locking the running wheels 14.

[0040] The sliding mechanism 4 is arranged in pairs on the left and right columns. The sliding mechanism 4 includes: a slide groove and a slide rail. The two ends of the slide groove are fixed on the square mounting holes arranged at equal intervals on the front and rear columns on each side, and extend in the horizontal direction. The slide rail can move along the slide groove, and the two sides of the support plate 2 are connected to the slide rail. Furthermore, the sliding mechanism 4 has a locking mechanism, which can lock the slide rail when the slide groove moves relative to the slide rail to the extreme position (i.e., the expanded state, the retracted state), and the locking mechanism can adopt the existing technology in the field.

[0041] Based on the above technical solution, this embodiment describes a specific implementation of the display mounting bracket 3:

[0042] like Figure 4 and Figure 5 As shown, the central shaft 31 includes a shaft base 311, a shaft support section 312, a shaft shoulder 313 and a shaft connection section 314 arranged in sequence. The shaft base 311 can be a flange plate with bolt holes provided thereon and fixed to the upper surface of the support plate 2 by bolts.

[0043] The rotating rod 32 is rotatably connected to the shaft connecting section 314. The diameter of the shaft connecting section 314 is smaller than the diameter of the shaft shoulder 313. The shaft shoulder 313 is used to limit and support the rotating rod 32. Specifically, one end of the rotating rod 32 is provided with a shaft connecting hole 321, which is sleeved on the shaft connecting section 314. The rotating rod 32 cooperates with the shaft connecting section 314 through a cylindrical pair and can rotate freely relative to the shaft connecting section 314.

[0044] The other end of the rotating rod 32 is provided with a display fixing seat installation interface for connecting with the display fixing seat. Specifically, the other end of the rotating rod 32 is set to be disc-shaped, with a bolt hole as the display fixing seat installation interface, and its upper and lower surfaces can be connected to the display fixing seat 33 by bolts.

[0045] This embodiment provides a specific implementation method: two rotating rods 32 are sequentially sleeved on the shaft connecting section 314, and each rotating rod 32 is used to connect a display. Figure 4 and Figure 5 As shown, the two rotating rods 32 are sequentially sleeved on the shaft connecting section 314 from top to bottom. Figure 5 Taking the viewing angle of as an example, the two rotating rods are respectively the first rotating rod 32a and the second rotating rod 32b, wherein the first rotating rod 32a is located below the second rotating rod 32b. This solution realizes that the two displays 5 are arranged side by side for easy observation.

[0046] The two rotating rods 32 have the same structure. The first rotating rod 32a is installed upright, and the second rotating rod 32b is installed upside down, so that the two displays are at the same height from the ground.

[0047] Furthermore, a damping pad assembly 34 is sleeved on the shaft connection section 314, one set of damping pad assemblies 34 is arranged above the second rotating rod 32b, and another set of damping pad assemblies 34 is arranged below the first rotating rod 32a. The damping pad assembly 34 is used to provide rotation damping for the corresponding rotating rod.

[0048] Furthermore, a stop pin 35 is provided on the shaft shoulder 313 of the central shaft 31 to limit the rotation angle of the rotating rod 32. Specifically, the stop pin 35 extends vertically, is arranged side by side and spaced apart from the shaft connecting section 314 of the central shaft, and is fixed on the upper surface of the shaft shoulder 313. Correspondingly, a stop protrusion 322 is provided on the side of the rotating rod 32, and the stop pin 35 cooperates with the stop protrusion 322 to limit the rotation angle of the rotating rod 32.

[0049] Specifically, from a top view, the first rotating rod 32a rotates counterclockwise, and when the stop protrusion 322 is rotated to contact the stop pin 35, the stop pin 35 prevents the stop protrusion 322 from continuing to rotate, thereby limiting the rotation angle of the first rotating rod 32a. The second rotating rod 32b rotates clockwise, and when the stop protrusion 322 is rotated to contact the stop pin 35, the stop pin 35 prevents the stop protrusion 322 from continuing to rotate, thereby limiting the rotation angle of the second rotating rod 32b.

[0050] Furthermore, a lower stop washer assembly 36 is used, which is sleeved on the shaft connection end 314 of the central shaft and is located between the two rotating rods 32. An upper stop washer 37 is used, which is sleeved on the shaft connection end 314 of the central shaft and is located above the damping washer assembly 34 at the top.

[0051] A threaded section 315 is also provided at the upper portion of the shaft connection section 314. The threaded section 315 and the shaft connection section form a stepped shaft 314. The diameter of the threaded section 315 is smaller than the diameter of the shaft connection section 314. The fastener assembly 38 is located above the upper stop washer 37 and is connected with the external thread of the threaded section 315 at the upper portion of the shaft connection section 314. The fastener assembly 38 limits the upper stop washer 37, the damping washer assembly 34, the second rotating rod 32b, the lower stop washer assembly 36, the first rotating rod 32a, and the damping washer assembly 34 on the central shaft 31.

[0052] The fastener assembly 38 specifically includes: a flat washer, a spring washer and a hexagonal nut, which are used to constrain the components on the central axis.

[0053] A specific solution is: Figure 6 As shown, the damping gasket assembly 34 includes two flat washers 341 and a butterfly gasket 342 , and the butterfly gasket 342 is located between the two flat washers 341 .

[0054] like Figure 7 As shown, the lower stop gasket assembly 36 includes: two flat gaskets 361 and a lower stop gasket 362. The lower stop gasket is located between the two flat gaskets 361, and the lower stop gasket 362 is provided with a limit bayonet 363 for accommodating the stop pin 35. The limit bayonet 363 is an arc-shaped structure, which is clamped on the outer cylindrical surface of the stop pin 35 and cooperates with the central axis through a rotation pair. The lower stop gasket cooperates with the stop pin 35 through the bayonet 363 to limit the rotation of the lower stop gasket 362.

[0055] like Figure 5 As shown, the upper stop washer 37 has a connecting protrusion, which is provided with a bolt hole and is connected to the top of the stop pin 35 by bolts. Further, the center hole of the upper stop washer 37 is an oblong hole, having two opposite planes and two opposite arc surfaces. Correspondingly, two opposite stop planes 316 are provided on the side of the shaft connecting section 314, and the upper stop washer 37 is sleeved on the two stop planes 316 of the shaft connecting section 314, so as to limit the rotation of the upper stop washer 37.

[0056] The stop pin 35 is a cylindrical pin, the bottom end of which is connected to the shaft shoulder 313 and the other end of which is connected to the upper stop washer 37 .

[0057] Based on the above technical solution, this embodiment also provides an implementation method, such as Figure 1 , Figure 8 and Fig. 9 As shown, it also includes a display limiting component 6, which is arranged on the supporting plate 2 and is used to limit the display 5 when the display 5 is in the storage state.

[0058] One embodiment: the display limit assembly 6 comprises: a lower sealing plate 61, a spring 62, a locking tongue 63 and a support block 64. The lower sealing plate 61 is arranged on the upper surface of the support plate 2, and a convex column 611 is arranged on the upper surface of the lower sealing plate 61. The spring 62 is sleeved on the convex column 611. The locking tongue 63 is connected to the top end of the spring 62, and the top of the locking tongue 63 has a guiding inclined surface 631, the side has a pressing portion 632, and the back of the locking tongue is a plane.

[0059] Bolt holes are provided on the support block 64, which is fixed to the upper surface of the support plate 2 by bolts. An activity space for accommodating the lock tongue 63 is provided inside the support block 64, and the opening of the activity space faces downward, and the lock tongue 63 enters the activity space upward from the opening. An opening is provided on the top surface of the support block 64, and the lock tongue 63 extends upward from the opening under the elastic force of the spring. A pressing channel connected to the activity space is provided on the side of the support block 64, and a pressing portion 632 extends from the pressing channel. When the operator presses the pressing portion 632 downward with his fingers, the lock tongue 63 can move downward to retract into the activity space.

[0060] When the display 5 is folded, the display 5 starts to rotate horizontally from one side of the guiding slope 631, and pressure is applied to the guiding slope 631, causing the locking tongue 63 to move downward until the display 5 rotates to a position beyond the locking tongue 63. When pressure is no longer applied to the locking tongue 63, the locking tongue 63 automatically returns to its initial state under the rebound force of the spring and extends out from the opening. The back of the locking tongue 63 prevents the display 5 from rotating in the opposite direction, thereby limiting the rotation of the display 5.

[0061] When the display 5 needs to be unfolded, the pressing portion 632 is pressed downward to move the locking tongue 63 downward into the retracted activity space, and then the display 5 can be rotated to unfold outward.

[0062] Furthermore, buffer pads 15 are provided on the columns of the cabinet body 1, specifically on the two columns on the side where the support plate 2 can enter and exit. The specific position of the buffer pads 15 is set according to the position of the display fixing seat 33, so that when the display 6 is in the unfolded state, the buffer pads 15 stop and buffer the display fixing seat 33. The buffer pads 15 can be made of materials such as wool felt and rubber.

[0063] Based on the above scheme, when the monitor needs to be used: first unlock the slide rail and pull out the tray 2 to the self-locking state of the slide rail; then open the monitor limit assembly 6 of the left and right monitors, and turn the left and right monitors around the center axis 31 to the limit position of the stop pin 35; finally, unlock the slide rail and push the tray 2 to the self-locking state of the slide rail. At this time, the back of the monitor is pressed on the buffer pad 15 of the column of the cabinet body 1, and the monitor is unfolded close to the cabinet column.

[0064] To fold the display, follow the reverse steps: first unlock the slide rail, pull out the tray 2 until the slide rail is self-locking; move the display until it is locked by the display limit assembly 6; then unlock the slide rail, push the tray 2 into the cabinet body 1 until the slide rail is self-locking, and the display is folded.
