Description

Technical Field

[0001] This invention relates to the field of multimedia central control equipment technology, and more specifically, to a central control system for a digital multimedia exhibition hall. Background Technology

[0002] Central control refers to the central control system, which is a device that centrally manages and controls various devices such as sound, light, and electricity.

[0003] Currently, in order to prevent dust from entering the sockets during use, central control system devices are equipped with dustproof protection. However, the dustproof protection structure tends to occupy the internal space of the central control system device, thereby increasing the size of the central control system device and thus increasing its production cost. Furthermore, the dustproof protection structure of the central control system device is not convenient for sealing and dustproofing unplugged sockets after the plug is inserted into the socket.

[0004] For example, CN218472388U discloses a central control system for a digital multimedia exhibition hall. The central control device has a main body with two grooves, which are interconnected. A protective plate is installed inside the first groove, and a limit plate is fixedly connected to one side of the protective plate. The limit plate has a through hole. A U-shaped pressure rod is movably connected inside the second groove. One end of the U-shaped pressure rod is located in the through hole, and the other end passes through one side of the second groove. The first groove has two guide grooves. A handle and a guide block are fixedly connected to the protective plate. The guide block is slidably connected to the guide groove. A spring is fixedly connected to one side of the protective plate.

[0005] As can be seen from the above-mentioned disclosed scheme, the socket is protected and sealed by the protective plate. However, when assembling the protective plate, it is necessary to open groove one and groove two as well as guide groove, and also to set springs and other components, which is quite complicated and cumbersome, and occupies a large space. Furthermore, after a plug is inserted, the protective plate cannot seal the opening of groove one, leaving other sockets exposed and reducing their sealing performance. Summary of the Invention

[0006] To address the problems existing in the prior art, the present invention aims to provide a central control system for a digital multimedia exhibition hall. This system, through the use of a protective cover with openings and sealing bristles, not only facilitates sealing of the anti-cavity groove but also does not affect the insertion of plugs and sockets. Furthermore, after the plug is inserted, the sealing bristles allow wires to pass through the protective cover, greatly improving the sealing effect. Additionally, the adsorption plate, grooves, and adsorption blocks on the protective cover facilitate opening and closing of the cover, and the structure is simple, not occupying internal space of the central control device body, and not increasing the size of the central control device body, thereby reducing production costs.

[0007] To solve the above problems, the present invention adopts the following technical solution.

[0008] A central control system for a digital multimedia exhibition hall includes a central control unit body. The surface of the central control unit body is provided with a groove, a display screen, and buttons. The inner wall of the groove has a clearance groove, and the inner wall of the clearance groove has a socket. A protective cover is rotatably connected to one side of the groove opening via a hinge. The surface of the protective cover has an opening, and the inner wall of the opening is fixedly connected to symmetrical sealing bristles. A connecting plate is fixedly connected to one end of the central control unit body, and symmetrical shafts are fixedly connected to the side of the connecting plate. A mounting base is rotatably connected to the surface of the shafts. This central control system for the digital multimedia exhibition hall, through the protective cover and the opening and sealing bristles on the cover, not only facilitates sealing of the clearance groove but also does not affect the insertion of the plug and socket. Furthermore, after the plug is inserted, the sealing bristles facilitate the wires to pass through the protective cover, greatly improving the sealing effect. Additionally, the adsorption plate, groove, and adsorption block on the protective cover not only facilitate the opening and closing of the protective cover but also have a simple structure that does not occupy the internal space of the central control unit body, thus not increasing the size of the central control unit body and consequently its production cost.

[0009] Furthermore, symmetrical adsorption blocks are fixedly embedded in the inner wall of the groove. The adsorption blocks are made of magnetic material and are rectangular, polygonal, or circular in shape. The surface of the adsorption block is on the same plane as the bottom inner wall of the groove, and the adsorption block has the function of magnetic adsorption.

[0010] Furthermore, an adsorption plate is fixedly embedded on the inner surface of the protective cover. The adsorption plate is made of ferrous metal and has the same shape as the adsorption block. The adsorption plate is in contact with the adsorption block and can fix the closed position of the protective cover by magnetic adsorption force.

[0011] Furthermore, one side of the mounting base is provided with symmetrical side plates, and a positioning rod is inserted into the side of the side plate. One end of the positioning rod is provided with a manual knob for easy manual rotation of the positioning rod.

[0012] Furthermore, a connecting block is fixedly connected to the surface of the connecting plate, and a positioning hole is opened on one side of the connecting plate. The positioning hole is distributed in a ring with the shaft as the center, which facilitates the adjustment of the tilt angle of the mounting base.

[0013] Furthermore, the inner wall of the positioning hole is provided with an internal thread, and the surface of the positioning rod is provided with an external thread that matches the internal thread of the positioning hole.

[0014] Furthermore, there are two adsorption plates, and the surface of the adsorption plate is on the same plane as the inner surface of the protective cover.

[0015] Furthermore, an anti-slip plate is fixedly connected to the surface of the protective cover. The anti-slip plate is L-shaped and has anti-slip texture on its surface, which facilitates manual control of opening and closing of the protective cover.

[0016] Furthermore, the opening is strip-shaped, and the central axis of the opening is on the same plane as the center of the socket, which facilitates the passage of the plug wire through the protective cover, and the surface of the wire is sealed by the sealing hair.

[0017] Furthermore, the surface of the mounting base is provided with annularly evenly distributed mounting holes to facilitate the connection and fixation of the mounting base.

[0018] Compared with the prior art, the advantages of this invention are:

[0019] (1) The present invention, through the protective cover and the opening and sealing hair of the protective cover, not only facilitates the sealing of the anti-cavity groove, but also does not affect the plug and socket connection. At the same time, after the plug is plugged in, the sealing hair facilitates the wire to pass through the protective cover, which greatly improves its sealing effect.

[0020] (2) The present invention uses an adsorption plate, a groove and an adsorption block set in the protective cover, which not only facilitates the opening and closing of the protective cover, but also has a simple structure, does not occupy the internal space of the central control device body, does not increase the volume of the central control device body, and thus does not increase its production cost.

Detailed Implementation

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Example 1

[0030] Please see Figure 1-5 A central control system for a digital multimedia exhibition hall includes a central control device body 1. The central control device body 1 houses central control system components, the composition and working principle of which are well-known to those skilled in the art and will not be described in detail here. The surface of the central control device body 1 is provided with a groove 11, a display screen 14, and buttons 15. The groove 11 restricts the closing position of the protective cover 2 and simultaneously seals the anti-cavity groove 12, thereby sealing the socket 13. The inner wall of the groove 11 is provided with the anti-cavity groove 12, which has an anti-cavity function, ensuring that the protective cover 2 is not restricted from closing when the plug is inserted into the socket 13. The inner wall of the anti-cavity groove 12 is provided with the socket 13. The socket 13 is existing technology. A protective cover 2 is rotatably connected to the opening side of the groove 11 via a hinge. The surface of the protective cover 2 has an opening 21. The opening 21 allows the protective cover 2 to prevent the plug from being inserted, so that the plug wire is in the position of the opening 21. At this time, the sealing hair 22 seals the surface of the wire passing through the opening 21. Symmetrical sealing hairs 22 are fixedly connected to the inner wall of the opening 21. A connecting plate 4 is fixedly connected to one end of the central control device body 1. Symmetrical shafts 42 are fixedly connected to the side of the connecting plate 4. A mounting base 3 is rotatably connected to the surface of the shafts 42. The mounting base 3 can be angled through the connecting plate 4, which facilitates the fixation of the central control device body 1.

[0031] A connecting block 43 is fixedly connected to the surface of the connecting plate 4. A positioning hole 41 is opened on one side of the connecting plate 4. The positioning holes 41 are distributed in a ring with the shaft 42 as the center, which facilitates the adjustment of the tilt angle of the mounting base 3. The inner wall of the positioning hole 41 is provided with an internal thread. The surface of the positioning rod 32 is provided with an external thread that matches the internal thread of the positioning hole 41. There are two adsorption plates 24. The surface of the adsorption plate 24 is on the same plane as the inner surface of the protective cover 2. An anti-slip plate 23 is fixedly connected to the surface of the protective cover 2. The anti-slip plate 23 is L-shaped and has anti-slip texture on its surface, which facilitates the manual control of opening and closing of the protective cover 2. The opening 21 is strip-shaped. The central axis of the opening 21 is on the same plane as the center of the plug 13, which facilitates the plug wire to pass through the protective cover 2 and the surface of the wire is sealed by the sealing hair 22.

[0032] In this embodiment, the protective cover 2, the opening 21 and the sealing hair 22 provided in the protective cover 2 not only facilitate the sealing of the anti-cavity groove 12, but also do not affect the insertion of the plug and the socket 13. At the same time, after the plug is inserted, the sealing hair 22 facilitates the wire to pass through the protective cover 2, which greatly improves its sealing effect.

[0033] Example 2

[0034] Please see Figure 1-5 A central control system for a digital multimedia exhibition hall includes a central control device body 1. The central control device body 1 houses central control system components, the composition and working principle of which are well-known to those skilled in the art and will not be described in detail here. The surface of the central control device body 1 is provided with a groove 11, a display screen 14, and buttons 15. The groove 11 restricts the closing position of the protective cover 2 and simultaneously seals the anti-cavity groove 12, thereby sealing the socket 13. The inner wall of the groove 11 is provided with the anti-cavity groove 12, which has an anti-cavity function, ensuring that the protective cover 2 is not restricted from closing when the plug is inserted into the socket 13. The inner wall of the anti-cavity groove 12 is provided with the socket 13. The socket 13 is existing technology. A protective cover 2 is rotatably connected to the opening side of the groove 11 via a hinge. The surface of the protective cover 2 has an opening 21. The opening 21 allows the protective cover 2 to prevent the plug from being inserted, so that the plug wire is in the position of the opening 21. At this time, the sealing hair 22 seals the surface of the wire passing through the opening 21. Symmetrical sealing hairs 22 are fixedly connected to the inner wall of the opening 21. A connecting plate 4 is fixedly connected to one end of the central control device body 1. Symmetrical shafts 42 are fixedly connected to the side of the connecting plate 4. A mounting base 3 is rotatably connected to the surface of the shafts 42. The mounting base 3 can be angled through the connecting plate 4, which facilitates the fixation of the central control device body 1.

[0035] Symmetrical adsorption blocks 16 are fixedly embedded in the inner wall of the groove 11. The adsorption blocks 16 are made of magnetic material and are rectangular, polygonal, or circular in shape. The surface of the adsorption blocks 16 is on the same plane as the bottom inner wall of the groove 11. The adsorption blocks 16 have the function of magnetic adsorption. An adsorption plate 24 is fixedly embedded in the inner surface of the protective cover 2. The adsorption plate 24 is made of ferrous metal and has the same shape as the adsorption blocks 16. The adsorption plate 24 contacts the adsorption blocks 16 and can fix the closed position of the protective cover 2 by magnetic adsorption. A symmetrical side plate 31 is provided on one side of the mounting base 3. A positioning rod 32 is inserted into the side of the side plate 31. A manual knob is provided at one end of the positioning rod 32 for easy manual rotation of the positioning rod 32. The surface of the mounting base 3 is provided with annularly distributed mounting holes 33 for easy connection and fixation of the mounting base 3.

[0036] In this embodiment, the adsorption plate 24, groove 11, and adsorption block 16 provided by the protective cover 2 not only facilitate the opening and closing of the protective cover 2, but also have a simple structure, do not occupy the internal space of the central control device body 1, do not increase the volume of the central control device body 1, and thus do not increase its production cost.

[0037] After the plug and socket 13 are connected, the central control system of this digital multimedia exhibition hall rotates the protective cover 2 downwards to close it. At this time, the external wire of the plug is in the opening 21. The sealing hair 22 contacts and squeezes the surface of the wire to seal it, which does not affect the opening and closing of the protective cover 2. At the same time, it can prevent the socket 13 without plugging in the plug from being sealed. The protective cover 2, the opening 21 and the sealing hair 22 of the protective cover 2 not only facilitate the sealing of the anti-cavity groove 12, but also do not affect the plug and socket 13 connection. At the same time, after the plug is connected, the sealing hair 22 makes it easy for the wire to pass through the protective cover 2, which greatly improves its sealing effect. Furthermore, the adsorption plate 24, the groove 11 and the adsorption block 16 of the protective cover 2 not only facilitate the opening and closing of the protective cover 2, but also have a simple structure that does not occupy the internal space of the central control device body 1, and does not increase the volume of the central control device body 1, thereby increasing its production cost.

[0038] The above description is merely a preferred embodiment of the present invention; however, the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and its improved concept, should be covered within the scope of protection of the present invention.
