Description

Technical Field

[0001] The utility model relates to the technical field of hubs, and in particular to an Internet of Things device hub. Background Art

[0002] The Internet of Things refers to the connection of any object to the network through information sensing devices according to agreed protocols. Objects exchange and communicate information through information transmission media to achieve intelligent identification, positioning, tracking, supervision and other functions. A hub refers to a device that connects multiple Ethernet twisted pair cables or optical fiber collections under the same physical medium. The hub operates at the physical layer in the OSI model. It can be regarded as a multi-port repeater. If it detects a collision, it will submit a blocking signal. Therefore, in the Internet of Things, hubs are needed for centralized signal transmission in information transmission. However, different usage scenarios require different numbers of hubs for connecting multiple Ethernet twisted pair cables or optical fiber collections.

[0003] At present, hubs are all integrated with only one main body and a fixed number of interfaces. However, when in use, more interfaces are needed for Ethernet twisted pair cables or optical fiber collection connections. In order to increase the number of hub interfaces in the existing technology, multiple hubs need to be stacked together with screws. When assembling or separating, the screws can be repeatedly turned with tools until the screws are separated from the outside of the hub. Although the hub can be assembled and separated, it takes a lot of time and effort, which reduces the efficiency of assembling and separating the hub. Utility Model Content

[0004] In order to make up for the above deficiencies, the present invention provides an Internet of Things device hub, which aims to improve the existing technology in which, in order to increase the number of hub interfaces, multiple hubs need to be stacked together with screws, and the screws can be repeatedly turned with tools until the screws are separated from the outside of the hub. Although the hub can be assembled and separated, it takes a lot of time and effort, which reduces the efficiency of assembling and separating the hub.

[0005] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solution: an Internet of Things device hub, comprising:

[0006] Hub 1 and hub 2, hub 2 is movably installed on the top of hub 1.

[0007] There are two mounting plates symmetrically installed on the top of hub one and hub two, and limit plates are symmetrically installed on both sides of the top of the mounting plates, and two positioning plates for limiting themselves are symmetrically installed on both sides of the bottom of hub two.

[0008] The baffle is fixedly connected to one end of the mounting plate, and the tops of the baffle and the mounting plate are perpendicular to each other.

[0009] Multiple rows of plug-in columns are fixedly installed on one end of the positioning plate, and multiple rows of plug-in tubes that are compatible with the plug-in columns are fixedly installed on one side of the baffle close to the mounting plate.

[0019] A plurality of limiting balls are elastically installed along a straight line on both sides of the positioning plate, wherein adjacent sides of two adjacent limiting plates are each provided with a slot adapted to the limiting balls.

[0020] The utility model has the following beneficial effects:

[0021] In the present utility model, after the positioning plate approaches the baffle, multiple rows of plug-in posts are simultaneously inserted into the inner cavities of multiple rows of plug-in tubes until the end of the multiple rows of plug-in posts away from the positioning plate is in contact with the inner wall of the open end of the plug-in tube. At this time, the outer wall of the plug-in post is tightly fitted with the inner wall of the plug-in tube, which increases the friction between the inner wall of the plug-in tube and the outer wall of the plug-in post.

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] Reference Figure 1-5 , an embodiment provided by the utility model: an Internet of Things device hub, comprising;

[0031] Hub 1 and Hub 2 2, Hub 2 2 is movably installed on the top of Hub 1, Hub 1 1 and Hub 2 2 refer to devices that connect multiple Ethernet twisted pair cables or optical fibers to the same physical medium. It can be regarded as a multi-port repeater. If it detects a collision, it will submit a blocking signal.

[0032] There are two mounting plates 4 symmetrically installed on the top of hub 1 1 and hub 2 2. Limiting plates 3 are symmetrically installed on both sides of the top of the mounting plate 4. The limiting plates 3 on both sides of the top of the mounting plate 4 are perpendicular to the top of the mounting plate 4.

[0033] Two positioning plates 5 for limiting themselves are symmetrically installed on both sides of the bottom of hub 2. When hub 2 is placed on top of hub 1, one end of the positioning plate 5 is placed directly above the mounting plate 4, and then hub 2 is pushed until the positioning plate 5 slides between the two limiting plates 3.

[0034] The baffle 8 is fixedly connected to one end of the mounting plate 4, and the tops of the baffle 8 and the mounting plate 4 are perpendicular to each other. There are multiple rows of plug-in columns 6 fixedly installed at one end of the positioning plate 5. Multiple rows of plug-in tubes 9 compatible with the plug-in columns 6 are fixedly installed on the side of the baffle 8 close to the mounting plate 4. After the positioning plate 5 approaches the baffle 8, the multiple rows of plug-in columns 6 are simultaneously inserted into the inner cavity of the multiple rows of plug-in tubes 9 until the multiple rows of plug-in columns 6 are away from the end of the positioning plate 5 and fit together with the inner wall of the open end of the plug-in tube 9. At this time, the outer wall of the plug-in column 6 and the inner wall of the plug-in tube 9 are tightly fitted, which increases the friction between the inner wall of the plug-in tube 9 and the outer wall of the plug-in column 6. Under the action of friction, the plug-in column 6 is effectively prevented from detaching from the inside of the plug-in tube 9, thereby improving the installation stability between the hub 1 and the hub 2, 2, and effectively reducing the time and effort required for assembling the hub 1 and the hub 2, while improving the efficiency of assembling the hub 1 and the hub 2.

[0035] Furthermore, when it is necessary to separate hub 1 and hub 2 2, pull hub 2 2 in the reverse direction until the multiple rows of plug-in columns 6 are detached from the inside of the plug-in tube 9 and until the positioning plate 5 is pulled out from between the two adjacent limit plates 3, so that hub 2 2 can be detached from the top of hub 1 1.

[0036] The mounting plate 4 is set to an L-shaped structure, and one end of the mounting plate 4 is fixedly connected to one side of the baffle 8. The positioning plate 5 is set to a T-shaped structure, and the small end of the positioning plate 5 is fixedly connected to the bottom of the hub 2. When the positioning plate 5 is located between two adjacent limit plates 3, the small end of the positioning plate 5 extends through between the two adjacent limit plates 3 to directly above the limit plate 3, thereby limiting the positioning plate 5 to prevent the positioning plate 5 from detaching from between the two limit plates 3.

[0037] The end of the plug-in column 6 away from the positioning plate 5 is set to a tapered structure, which can improve the tolerance between the tip of the plug-in column 6 and the open end of the plug-in tube 9, and can improve the convenience of inserting the plug-in column 6 into the plug-in tube 9.

[0038] The plug-in column 6 is made of rubber material, which can further improve the tightness and friction between the outer wall of the plug-in column 6 and the inner wall of the plug-in tube 9.

[0039] The top of the baffle 8 and the top of the limit plate 3 are flush with each other. When the positioning plate 5 is inserted between two adjacent limit plates 3, the bottom of the hub 2 2 fits with the limit plate 3 and the top of the baffle 8, preventing the bottom of the hub 2 2 from being suspended in the air, thereby improving the installation stability of the hub 2 2.

[0040] A plurality of limiting balls 7 are elastically installed along a straight line on both sides of the positioning plate 5, wherein adjacent sides of two adjacent limiting plates 3 are provided with a slot adapted to the limiting balls 7. When the positioning plate 5 is inserted between the two adjacent limiting plates 3, the plurality of limiting balls 7 slide into the plurality of slots in turn as the positioning plate 5 continues to slide, thereby increasing the resistance of the positioning plate 5 when inserted into the interior of the two adjacent limiting plates 3, and avoiding the situation where the hub 1 and the hub 2 2 shake and separate.

[0041] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
