Description

Technical Field

[0001] This utility model belongs to the field of ship trackball technology, specifically relating to a ship trackball structure. Background Technology

[0002] Ships refer to all kinds of vessels, which are means of transportation that can navigate or anchor in waterways for transportation or operations. In order to enable ships to have higher navigation reliability and stronger long-distance sailing capabilities, ships usually carry trackball electronic devices to control their trajectory. The existing trackballs are devices that are mounted on ships to control their navigation trajectory. They are convenient to install and remove and can be effectively rolled.

[0003] Existing ship trackballs, during installation and use, and especially during frequent rolling of the trackball, tend to cause stress on the edge of the mounting cover ring and on the high-elasticity cotton. Prolonged stress on the high-elasticity cotton weakens its elasticity, reducing the tightness of the mounting cover ring. Furthermore, the rolling force causes the outer surface of the trackball to contact the inner surface of the mounting cover ring, sometimes resulting in severe friction and shaking, reducing the trackball's rolling sensitivity. This affects the enhanced elastic compression and rolling effect of the ship trackball during installation and use. Therefore, this utility model proposes a new ship trackball structure. Utility Model Content

[0004] The purpose of this utility model is to provide a ship trackball structure to solve the problems mentioned in the background art, such as the trackball ball easily causing stress on the edge of the mounting cover ring when it rolls and is subjected to force, and simultaneously stress on the high-elasticity cotton. Over time, the stress on the high-elasticity cotton can weaken its elasticity, reducing the tightness of the mounting cover ring. Furthermore, when the trackball ball is subjected to force, the outer surface of the ball can contact the inner surface of the mounting cover ring, and prolonged contact can even cause severe friction and shaking, reducing the sensitivity of the trackball ball's rolling motion.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a ship trackball structure, comprising a ship trackball body, the ship trackball body including an outer shell, a cover plate fixedly mounted on the bottom end of the outer shell by screws, an inner mounting shell provided at one end of the inner shell, a dustproof ring provided at the connection between the top of the inner mounting shell and the inner surface of the outer shell, and the inner mounting shell and the interior of the outer shell being fixed by screws, high-elasticity cotton provided at the edge of the inner surface of the inner mounting shell, a guide wheel mounted on the bottom end of the inner shell via a connecting shaft, a trackball ball rotatably connected to the interior of the inner mounting shell via the guide wheel, an installation cover ring provided at the connection between the top edge of the trackball ball and the high-elasticity cotton, and the ship trackball body also having:

[0006] A reinforced elastic compression rolling mechanism is provided, and the reinforced elastic compression rolling mechanism includes a reinforced elastic component disposed inside the high elastic cotton, and a mounting component is disposed on the inner surface of the mounting cover ring, and a compression rolling component is disposed inside the mounting component;

[0007] A moisture-absorbing mechanism, comprising a storage component disposed inside a cover plate, wherein an inlet / outlet component is mounted on one side of the storage component located on the side of the cover plate;

[0008] The reinforced elastic component includes a reinforced elastic ring that is snapped into the interior of the high-elasticity cotton. An elastic clip is integrally provided on the upper surface of the reinforced elastic ring, and a slot is formed at the inner top edge of the built-in mounting shell.

[0009] The mounting assembly includes a limiting groove formed at the edge of the inner surface of the mounting cover ring, and the limiting groove and the interior of the mounting cover ring are an integral structure;

[0010] The pressing and rolling assembly includes a limiting block installed inside a limiting groove. An elastic block is provided at the connection between the bottom end of the limiting block and the inside of the limiting groove. A ball rolls inside the limiting block, and the ball is in contact with the surface of the track ball.

[0011] The storage component includes a storage slot formed inside a cover plate, and a through hole is formed on the inner surface of the cover plate, and the through hole is connected to the internal structure of the storage slot.

[0012] The inlet / outlet assembly includes an inlet / outlet located on the side of the cover plate on one side of the storage tank, and the ends of the inlet / outlet are threaded with internal thread caps.

[0013] Preferably, the inner surface of the reinforcing elastic ring matches the inner surface structure of the high-elasticity cotton, and the reinforcing elastic ring is connected to the inner top of the built-in mounting shell by the elastic clip and the slot.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] By designing a reinforced elastic compression rolling mechanism, the track ball can roll normally. During long-term rolling, the mounting cover ring and the high-elasticity cotton are compressed and stressed. When the elasticity of the high-elasticity cotton weakens, the reinforced elastic ring still effectively compresses the installation. At the same time, on the inner surface of the mounting cover ring, the ball elastically contacts the surface of the track ball, which facilitates the smooth rolling of the track ball under the compression of the mounting cover ring. It is less likely to cause friction from contact with the inner surface of the mounting cover ring. It also facilitates the adjustment of the track ball's elastic compression rolling even after long-term operation, improving the reinforced elastic compression rolling effect of the ship's track ball body during installation and use.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1 to 6This utility model provides a technical solution: a ship trackball structure, including a ship trackball body 100, the ship trackball body 100 including an outer shell 101, a cover plate 102 fixedly installed at the bottom end of the outer shell 101 by screws, an inner mounting shell 105 provided at one end of the inner side of the outer shell 101, a dustproof ring 104 provided at the connection between the top end of the inner mounting shell 105 and the inner surface of the outer shell 101, so that the trackball ball 103 can be installed inside the inner mounting shell 105. The top end of the inner mounting shell 105 and the top end of the inner surface of the outer shell 101 are protected from dust by the dustproof ring 104, and the inner mounting shell 105 and the outer shell 101 are dustproof. The internal components of the 01 are fixed with screws. High-elasticity cotton 107 is provided at the inner surface edge of the inner mounting shell 105. A guide wheel 106 is mounted on the bottom of the inner part of the inner mounting shell 105 via a connecting shaft. A track ball 103 is rotatably connected to the inner part of the inner mounting shell 105 via the guide wheel 106. A mounting cover ring 108 is provided at the connection point between the top edge of the track ball 103 and the high-elasticity cotton 107. This facilitates the installation of the track ball 103 inside the inner mounting shell 105, where the high-elasticity cotton 107 and the mounting cover ring 108 are tightly pressed together. Conversely, it facilitates disassembly and installation / removal of the track ball 103. The ship track ball body 100 also includes:

[0025] The enhanced elastic compression rolling mechanism includes a reinforced elastic component disposed inside the high-elasticity cotton 107. An installation component is disposed on the inner surface of the mounting cover ring 108, and a compression rolling component is disposed inside the installation component. During installation and use, the enhanced elastic compression rolling mechanism facilitates the reinforced elastic compression connection of the high-elasticity cotton 107, while ensuring that the track ball 103 is pressed against the inner surface of the mounting cover ring 108 for smooth rolling and adjustment.

[0026] In order to facilitate the reinforced elastic connection of the high-elasticity cotton 107 by strengthening the elastic component and to keep it under constant elastic pressure, in this embodiment, preferably, the reinforced elastic component includes a reinforced elastic ring 1071 that is snapped into the inside of the high-elasticity cotton 107. An elastic clip 1072 is integrally provided on the upper surface of the reinforced elastic ring 1071. A slot 1073 is formed at the inner top edge of the inner mounting shell 105. The high-elasticity cotton 107 and the reinforced elastic ring 1071 can be snapped into the slot 1073 by the elastic clip 1072. After installation, the mounting cover ring 108 is always kept under the original elastic pressure and can be rolled for use.

[0027] In order to facilitate the elastic installation of the limiting block 1076 and the ball 1077 by means of the installation component, in this embodiment, preferably, the installation component includes a limiting groove 1074 formed at the edge of the inner surface of the installation cover ring 108, and the limiting groove 1074 and the interior of the installation cover ring 108 are an integral structure, which facilitates the limiting block 1076 to be limited and installed inside the limiting groove 1074.

[0028] In order to ensure that the inner surface of the mounting cover ring 108 and the outer surface of the track ball 103 are always in tight contact and rolling through the tight-pressing rolling assembly, in this embodiment, preferably, the tight-pressing rolling assembly includes a limiting block 1076 that is limited and installed inside the limiting groove 1074. An elastic block 1075 is provided at the connection between the bottom end of the limiting block 1076 and the inside of the limiting groove 1074. A ball 1077 rolls inside the limiting block 1076 and contacts the surface of the track ball 103. Under the elastic action of the elastic block 1075, the limiting block 1076 and the ball 1077 can be used to bring the ball 1077 into contact with the outer surface of the track ball 103, so that the track ball 103 can roll smoothly during tight-pressing installation and is not easily obstructed.

[0029] The moisture-absorbing mechanism includes a storage component disposed inside the cover plate 102. An access component is installed on one side of the storage component located on the side of the cover plate 102. The ship trackball body 100 can be installed and used. When moisture enters the interior of the outer shell 101, the moisture-absorbing mechanism can treat the moisture entering the interior of the outer shell 101, which is less likely to cause internal moisture damage and extends the service life.

[0030] In order to facilitate the storage of dry particles through the storage component and prevent moisture absorption, in this embodiment, preferably, the storage component includes a storage groove 1021 formed inside the cover plate 102. The inner surface of the cover plate 102 is provided with a through hole 1022, and the through hole 1022 is connected to the internal structure of the storage groove 1021. After the dry particles are stored inside the storage groove 1021, when moisture enters the interior of the outer shell 101, the dry particles can absorb the moisture from the interior through the through hole 1022.

[0031] In order to facilitate the entry and exit of dry particles into the storage tank 1021 through the entry and exit component, in this embodiment, preferably, the entry and exit component includes an inlet and outlet 1024 disposed on one side of the storage tank 1021 located on the side of the cover plate 102. The end of the inlet and outlet 1024 is threaded with an internal threaded cover 1023. Dry particles can enter into the storage tank 1021 through the inlet and outlet 1024, and the internal threaded cover 1023 can be rotated to seal the inlet and outlet 1024, and vice versa for easy replacement.

[0032] The working principle and usage process of this utility model are as follows: Before using this type of ship trackball structure, the first step is to install it. The reinforcing elastic ring 1071 can be engaged inside the high elastic cotton 107. Then, the elastic clip 1072 is engaged inside the clip groove 1073 to engage the reinforcing elastic ring 1071 and the high elastic cotton 107. Thus, the mounting cover ring 108 is elastically installed through the reinforcing elastic ring 1071 and the high elastic cotton 107. Then, the trackball 103 is closed inside the inner mounting shell 105 and contacts the surface of the guide wheel 106 for installation. At this time, the high elastic cotton 107 elastically presses the mounting cover ring 108 to quickly press the trackball 103 into place. During the pressing installation, the trackball 103 rolls without obstruction and allows the trackball 103 to roll normally.

[0033] Therefore, during prolonged rolling operation after installation, the mounting cover ring 108 and the high-elasticity cotton 107 are compressed and stressed. When the elasticity of the high-elasticity cotton 107 weakens, the reinforcing elastic ring 1071 still effectively presses it tightly. At the same time, during rolling, the elastic block 1075 deforms, causing the limiting block 1076 to elastically connect with the ball 1077 until the ball 1077 elastically contacts the surface of the track ball 103. This facilitates the smooth rolling of the track ball 103 under the tight pressure of the mounting cover ring 108, making it less likely to cause friction with the inner surface of the mounting cover ring 108. It also facilitates the elastic tight pressing and rolling adjustment of the track ball 103 during long-term operation, making the rolling adjustment smoother and improving the enhanced elastic tight pressing and rolling effect of the ship track ball body 100 during installation and use.

[0034] Finally, when the ship trackball body 100 is installed and used, after the cover plate 102 is fixed to the surface of the outer shell 101, dry particles larger than the gap of the through hole 1022 are injected into the storage tank 1021 through the inlet and outlet 1024, and the inner thread cover 1023 is rotated to close and seal the end of the inlet and outlet 1024. In this way, when the ship trackball body 100 is used for a long time after installation and the interior becomes damp, the moisture is sucked in through the through hole 1022 and the dry particles in the storage tank 1021, so that the electronic components installed inside the outer shell 101 are not easily damaged by moisture, extending their service life, improving the convenience of moisture absorption treatment inside the ship trackball body 100 after installation and use, and the dry particles in the storage tank 1021 can be replaced periodically.

[0035] Although embodiments of the present invention have been shown and described (see the detailed description above), it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
