Description

Technical Field

[0001] This utility model relates to the field of display screens, specifically to a shipboard display screen with a vibration damping structure. Background Technology

[0002] Marine displays are the core output of a ship's information system and play a vital role. They are not only a platform for intuitively displaying navigation data, but also key equipment for ensuring ship safety and improving navigation efficiency. Marine displays can display key navigation parameters such as the ship's position, speed, course, water depth, and weather in real time, helping the crew to accurately grasp the ship's status and the surrounding environment.

[0003] Existing displays still have the following problems when in use: When ships are sailing, they will be quite bumpy when they encounter waves. When the display is installed, it is usually wrapped with materials such as vibration damping foam to prevent the display from being affected by vibration. However, the effect of vibration damping materials deteriorates after a long period of use, resulting in a weakening of the vibration damping effect. Replacing the vibration damping materials is also quite inconvenient.

[0004] Therefore, it is necessary to invent a shipboard display screen with a vibration damping structure to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a shipboard display screen with a vibration damping structure to solve the problems mentioned in the background art, which are that ships encounter waves and are quite bumpy when sailing. During installation, the display screen is usually wrapped with vibration damping sponge and other materials to prevent the display screen from being affected by vibration. However, the vibration damping material becomes less effective after a long period of use, resulting in a weakening of the vibration damping effect, and the replacement of the vibration damping material is inconvenient.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a shipboard display screen with a vibration damping structure, comprising an outer frame, a back plate mounted on the bottom of the outer frame by mounting screws, a screen panel fitted into the inner wall of the outer frame, and vibration damping foam installed between the screen panel and the back plate. The vibration damping foam and the outer frame are movably mounted by a mounting assembly, and the mounting assembly is internally secured to prevent the parts from detaching from the outer frame by an anti-detachment component.

[0007] Preferably, the installation component includes a threaded sleeve that is fixedly fitted inside the vibration damping sponge, and the inner ring of the threaded sleeve is threadedly connected to a threaded rod, and the threaded rod is threadedly connected to a threaded groove reserved inside the outer frame, so as to ensure quick assembly and disassembly of the vibration damping sponge and the outer frame.

[0008] Preferably, there are two threaded rods, and the two threaded rods are symmetrically arranged with reference to the central axis of the vibration damping sponge. Both ends of the two threaded rods that are not connected to the threaded sleeve are fixedly installed with a dial plate. The dial plate has a serrated edge, which facilitates the dial plate to drive the threaded rod to rotate and realize the engagement and disengagement of the threaded connection between the threaded rod and the threaded sleeve.

[0009] Preferably, the mounting component also includes notches preset on both sides of the outer frame, and a lever is rotatably connected inside the notch to facilitate subsequent lever movement.

[0010] Preferably, the anti-detachment component includes an annular groove that is pre-set inside the threaded groove and connected to the threaded groove, and an annular block is rotatably connected inside the annular groove. A connecting rod is fixedly connected to the inner wall of the annular block. The connecting rod is slidably connected to the square groove reserved inside the threaded rod. In this way, the anti-detachment component can be set without affecting the rotation of the threaded rod or the movement of the threaded rod in the threaded groove when it rotates.

[0011] Preferably, the outer wall of the connecting rod is attached to the inner wall of the square groove to achieve a sliding connection, and the two sides of the square groove are in an open state, while the two ends of the square groove are in a closed state, so that the threaded rod is always threadedly connected to the threaded groove and does not fall off.

[0012] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0013] 1. This utility model allows the rotation of the notch-driven lever plate to achieve a threaded connection between the threaded rod and the threaded sleeve fixedly installed inside the vibration-damping sponge. Continuous rotation of the threaded rod causes it to separate from the threaded sleeve, making it easy to remove the vibration-damping sponge and install a new one. The new vibration-damping sponge is then aligned with the back of the screen panel and installed. Rotating the threaded rod in the opposite direction causes it to move towards the threaded sleeve fixedly connected inside the new vibration-damping sponge, thus achieving a threaded connection. This completes the installation of the new vibration-damping sponge. This method facilitates replacement of the vibration-damping sponge when it ages and its vibration-damping effect is affected after prolonged use.

[0014] 2. The annular groove is located inside the threaded groove and is connected to the threaded groove, so that the connecting rod is always located inside the threaded groove. The connecting rod is also movably fitted with the square groove reserved inside the threaded rod, so that the threaded rod is always located inside the threaded groove, preventing the threaded rod from falling off the threaded groove.

[0022] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0023] This utility model provides, for example Figures 1-4 The shipboard display screen with a vibration damping structure shown includes an outer frame 1. A back plate 2 is installed on the bottom of the outer frame 1 by mounting screws 3. The back plate 2 can be removed and installed by twisting the mounting screws 3, thereby allowing the vibration damping sponge 5 to be replaced. A screen panel 4 is fitted into the inner wall of the outer frame 1, and a vibration damping sponge 5 is installed between the screen panel 4 and the back plate 2. The vibration damping sponge 5 and the outer frame 1 are movably installed by a mounting assembly 6, and the mounting assembly 6 is connected to the outer frame 1 by an anti-detachment assembly 7.

[0024] During use, the notch 604 is used to rotate the dial plate 605, which in turn drives the threaded rod 602, which is fixedly connected to the dial plate 605, to rotate. The threaded rod 602 is threadedly connected to the threaded groove 603 reserved inside the outer frame 1. At the same time, the threaded rod 602 is threadedly connected to the threaded sleeve 601, which is fixedly fitted inside the vibration damping sponge 5. This causes the position of the threaded rod 602 and the threaded sleeve 601 to change when the rod rotates, continuously twisting the threaded rod 602 to separate it from the threaded sleeve 601. This makes it easy to remove the vibration damping sponge 5 and install a new one. The vibration damping sponge 5 can be easily removed with a screwdriver or other tools. The new vibration damping sponge 5 is then aligned with the back of the screen panel 4 and installed. The threaded rod is then rotated. The rod 602 rotates in the opposite direction, causing the threaded rod 602 to move towards the threaded sleeve 601, which is fixedly connected inside the new vibration-damping sponge 5, and rotate with the threaded sleeve 601 to achieve a threaded connection. This completes the installation of the new vibration-damping sponge 5. At the same time, when the threaded rod 602 rotates, the connecting rod 703, which is movably fitted inside the square groove 704 inside the threaded rod 602, is fixedly connected to the inner wall of the annular block 702, which is rotatably connected inside the annular groove 701. This ensures that the rotation of the threaded rod 602 is not affected by the anti-detachment component 7. At the same time, when the position of the threaded rod 602 moves, the square groove 704 moves outside the connecting rod 703. Thus, the rotation and position movement of the threaded rod 602 are not affected.

[0025] The mounting component 6 includes a threaded sleeve 601 that is fixedly fitted inside the vibration damping sponge 5. The inner ring of the threaded sleeve 601 is threadedly connected to a threaded rod 602, and the threaded rod 602 is threadedly connected to a pre-reserved threaded groove 603 inside the outer frame 1. The mounting component 6 also includes notches 604 pre-set on both sides of the outer frame 1, and a lever 605 is rotatably connected inside the notch 604 to facilitate subsequent movement of the lever 605 and ensure quick assembly and disassembly of the vibration damping sponge 5 from the outer frame 1. By rotating the threaded rod 602, the threaded rod 602 moves towards the threaded sleeve 601 fixedly connected inside the vibration damping sponge 5, thereby achieving a threaded connection with the threaded sleeve 601, thus completing the installation of the vibration damping sponge 5.

[0026] Two threaded rods 602 are provided, and the two threaded rods 602 are symmetrically arranged with reference to the central axis of the vibration damping sponge 5. The ends of the two threaded rods 602 that are not connected to the threaded sleeve 601 are fixedly installed with a lever plate 605. The edge of the lever plate 605 is serrated, which facilitates the lever plate 605 to drive the threaded rod 602 to rotate, so as to realize the engagement and disengagement of the threaded connection between the threaded rod 602 and the threaded sleeve 601.

[0027] The anti-detachment component 7 includes an annular groove 701 pre-set inside the threaded groove 603 and connected to the threaded groove 603. An annular block 702 is rotatably connected inside the annular groove 701, and a connecting rod 703 is fixedly connected to the inner wall of the annular block 702. The connecting rod 703 is slidably connected to the square groove 704 reserved inside the threaded rod 602. In this way, the anti-detachment component 7 can be set without affecting the rotation of the threaded rod 602 or the positional movement of the threaded rod 602 inside the threaded groove 603 when it rotates.

[0028] The outer wall of the connecting rod 703 is attached to the inner wall of the square groove 704 to achieve a sliding connection. The two sides of the square groove 704 are open, and the two ends of the square groove 704 are closed, so that the threaded rod 602 is always threadedly connected to the threaded groove 603 and does not fall off. The annular groove 701 is located inside the threaded groove 603 and is connected to the threaded groove 603.

[0029] This ensures that the connecting rod 703 is always inside the threaded groove 603, and the connecting rod 703 is also movably fitted with the square groove 704 reserved inside the threaded rod 602, thus ensuring that the threaded rod 602 is always inside the threaded groove 603 and preventing the threaded rod 602 from falling off the threaded groove 603.

[0030] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
