Description

Technical Field

[0001] This invention relates to the field of Internet of Things (IoT) communication technology, specifically to a communication device for an IoT terminal. Background Technology

[0002] An IoT terminal is a device in the Internet of Things (IoT) that connects the sensor network layer and the transmission network layer, enabling it to collect data and send data to the network layer. It performs multiple functions, including data acquisition, preliminary processing, encryption, and transmission.

[0003] Patent application number CN202120249079.7 discloses a reliable waterproof structure for an IoT terminal compatible with various cables and interfaces. The structure includes an IoT terminal body, a circuit board, and reserved signal test points. A universal connection hole is fixedly provided on the inner wall of the IoT terminal body. This patented reliable waterproof structure, compatible with various cables and interfaces, solves the problem of existing IoT terminals requiring multiple holes of different diameters to accommodate different wire diameters, resulting in poor waterproofing.

[0004] Currently, a large number of IoT terminals are directly installed on the walls of buildings. In order to further protect the IoT terminals, cabinets such as power distribution cabinets are used to cover the outside of the IoT terminals. Due to the limited internal space of the power distribution cabinet, maintenance personnel need to reach into the power distribution cabinet to operate the IoT terminals when routine maintenance is required. The space limitation restricts the maintenance work of the IoT terminals, making the maintenance work inconvenient. Summary of the Invention

[0005] The purpose of this invention is to provide a communication device for an Internet of Things (IoT) terminal to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides a communication device for an Internet of Things (IoT) terminal, comprising a main body of the communication terminal device, which is installed in a communication power distribution cabinet. Lugs are provided at both the top and bottom edges of the main body of the communication terminal device, and bolts with handles are provided on the lugs. A base plate is provided at the back of the main body of the communication terminal device, and bosses are provided at both the top and bottom edges of the front face of the base plate. The back of the main body of the communication terminal device abuts against the bosses. The end of the bolt with handle passes through the lugs and is threadedly connected to the bosses. A pair of extension components are hinged between the main body of the communication terminal device and the base plate. The extension components are formed by sequentially hinged multiple hinge rods, which have the same overall structure and gradually decrease in size.

[0007] As a further improvement to this technical solution, a pair of fixed seats are fixed on the back of the main body of the communication terminal device. The fixed seats are horizontally placed on the back of the main body of the communication terminal device. Both the left and right ends of the fixed seats are provided with hinge shafts. Several hemispherical grooves are opened on the end face of the fixed seats at the root of the hinge shafts. The grooves are arranged in a ring at equal intervals around the hinge shafts.

[0008] As a further improvement to this technical solution, the base plate is fixed on the inner wall of the communication distribution cabinet, and a pair of side seats are fixed on both the upper and lower sides of the front end face of the base plate. The two pairs of side seats are symmetrically distributed in the vertical direction on the front end face of the base plate.

[0009] As a further improvement to this technical solution, the two extension components are symmetrically distributed in the vertical direction in the gap between the main body of the communication terminal device and the base plate. The first end of the extension component is hinged to the fixed seat, and the tail end of the extension component is hinged to the side seat.

[0010] As a further improvement to this technical solution, the hinge rod has a U-shaped rod structure. The left and right end faces of the tail end of the hinge rod are provided with convex shafts, and the left and right end faces of the head end of the hinge rod are provided with sleeve holes. When two adjacent hinge rods are combined, the convex shaft on the first hinge rod extends into the sleeve hole at the head end of the other hinge rod, so that the two adjacent hinge rods are hinged to each other through the convex shaft. When the hinge rod located on the inner side rotates around the convex shaft inside the hinge rod located on the outer side, the hinge rod located on the inner side can retract into the inner side of the hinge rod located on the outer side.

[0011] As a further improvement to this technical solution, several positioning grooves are also provided on the left and right end faces of the tail end of the hinge rod. The positioning grooves are hemispherical in shape and are arranged in a ring with equal spacing around the convex axis. The size of the positioning grooves is the same as the size of the grooves.

[0012] As a further improvement to this technical solution, a fan-shaped limiting groove is provided on both the left and right end faces of the first end of the hinge rod. The limiting groove is connected to the sleeve hole. A shaft hole is provided on the outer end face of the side seat. A fan-shaped groove is provided on the outer end face of the side seat. The fan-shaped groove is connected to the shaft hole. The convex shaft on the outermost hinge rod is inserted into the shaft hole. The hinge shaft is inserted into the sleeve hole on the innermost hinge rod.

[0013] As a further improvement to this technical solution, a stop block is embedded at the end of the hinge shaft, and the stop block extends into the limiting groove; a limiting block is embedded at the end of the convex shaft, and the limiting block extends into the fan-shaped groove.

[0014] As a further improvement to this technical solution, a first mounting hole is provided on the side end face of the side seat, and a second mounting hole is provided on the side end face of the first end of the hinge rod. A steel ball is fitted in both the first mounting hole and the second mounting hole, and a sealing bolt is threaded to the opening of both the first mounting hole and the second mounting hole. A spring is provided between the sealing bolt and the steel ball.

[0015] As a further improvement to this technical solution, under the elastic force of the spring, the steel ball on the outermost hinge rod extends into the groove, the steel balls on the other hinge rods extend into the positioning groove of the adjacent hinge rod, and the steel ball in the side seat extends into the positioning groove of the innermost hinge rod.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0017] 1. In the communication device of this IoT terminal, a foldable extension component is installed between the communication terminal device body and the base plate behind the main body of the communication terminal device. This allows the main body of the communication terminal device to move freely in and out of the communication distribution cabinet after being released from the base plate. This enables the main body of the communication terminal device to extend directly out of the communication distribution cabinet, allowing maintenance personnel to perform maintenance work on the main body of the communication terminal device directly from the outside of the communication distribution cabinet. This avoids the inconvenience of maintaining the main body of the communication terminal device inside the communication distribution cabinet due to the small internal space.

[0018] 2. In the communication device of this IoT terminal, the block set on the main body of the communication terminal device, the fan-shaped groove set on the base plate, and the limiting block and limiting groove set on the extension component limit the angle between the hinge rod and the fixed seat, between two adjacent hinge rods, and between the hinge rod and the side seat when the main body of the communication terminal device extends outward in the communication distribution cabinet and the extension component is stretched. This prevents the extension component from being unable to retract back to its original shape when two adjacent hinge rods move to a flat state during the extension component being stretched.

[0019] 3. In the communication device of this IoT terminal, the groove, positioning slot steel ball, and spring are designed so that the steel ball can always be inserted into the groove and positioning slot under the elastic force of the spring. This allows the extension component to be positioned under the action of the steel ball when the main body of the communication terminal device moves to extend or retract. This makes it easier for maintenance personnel to perform maintenance work on the main body of the communication terminal device. Attached Figure Description

[0036] 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.

[0037] Please see Figures 1-12 As shown, the present invention provides a communication device for an Internet of Things (IoT) terminal, including a communication terminal device body 1, which is installed in a communication distribution cabinet 4. The communication terminal device body 1 has lugs 11 at both the top and bottom edges, and bolts with handles 12 are provided on the lugs 11. A base plate 2 is provided on the back of the communication terminal device body 1 and is fixed to the inner wall of the communication distribution cabinet 4. The base plate 2 has bosses 21 at both the top and bottom edges of the front face of the base plate 2. The back of the communication terminal device body 1 rests against the bosses 21. The positions of the bosses 21 and the lugs 11 correspond to the positions of the lugs 11. The end of the bolt with handle 12 passes through the lugs 11 and is threadedly connected to the bosses 21.

[0038] By pressing the main body 1 of the communication terminal equipment against the boss 21 and then tightening the bolt with handle 12, the main body 1 of the communication terminal equipment is fixed to the boss 21, thereby fixing the main body 1 of the communication terminal equipment to the base plate 2, thus achieving the purpose of fixing the main body 1 of the communication terminal equipment in the communication distribution cabinet 4.

[0039] In this invention, the main body 1 of the communication terminal device is hinged to a base plate 2 with a pair of extension components 3. The extension components 3 are formed by multiple hinge rods 31 being hinged sequentially. The multiple hinge rods 31 have the same overall structure and their dimensions gradually decrease. The hinge rods 31 have a U-shaped rod structure. The left and right end faces of the tail end of the hinge rod 31 are provided with a convex shaft 32, and the left and right end faces of the head end of the hinge rod 31 are provided with a sleeve hole 34.

[0040] When two adjacent hinge rods 31 are combined, the convex shaft 32 on the first hinge rod 31 extends into the sleeve hole 34 at the head end of the other hinge rod 31, so that the two adjacent hinge rods 31 are hinged to each other through the convex shaft 32.

[0041] When the inner hinge rod 31 rotates around the convex shaft 32 inside the outer hinge rod 31, the inner hinge rod 31 can retract into the inside of another hinge rod 31 located outside the hinge rod 31.

[0042] When the first end of the extension component 3 is pulled outward, multiple hinge rods 31 can gradually unfold outward under the pull, so that the extension component 3, which is in a retracted state, can extend outward. This allows the main body 1 of the communication terminal equipment to extend outward from the inside of the communication distribution cabinet 4 under the action of the extension component 3. This makes it convenient for maintenance personnel to perform maintenance work on the main body 1 of the communication terminal equipment directly from the outside of the communication distribution cabinet 4, preventing the situation where the main body 1 of the communication terminal equipment is difficult to maintain due to the limited space inside the communication distribution cabinet 4.

[0043] Specifically, a pair of fixed seats 13 are fixed on the back of the main body 1 of the communication terminal equipment. The fixed seats 13 are horizontally placed on the back of the main body 1 of the communication terminal equipment. A pair of side seats 22 are fixed on both the upper and lower sides of the front end face of the base plate 2. The two pairs of side seats 22 are symmetrically distributed in the vertical direction on the front end face of the base plate 2. Two extension components 3 are symmetrically distributed in the vertical direction in the gap between the main body 1 of the communication terminal equipment and the base plate 2. The first end of the extension component 3 is hinged to the fixed seat 13, and the tail end of the extension component 3 is hinged to the side seat 22, so that the main body 1 of the communication terminal equipment and the base plate 2 are connected together through the extension components 3.

[0044] Furthermore, both ends of the fixed base 13 are provided with hinge shafts 131, and the outer end face of the side base 22 is provided with a shaft hole 221. The convex shaft 32 on the outermost hinge rod 31 is inserted into the shaft hole 221, and the hinge shaft 131 is inserted into the sleeve hole 34 on the innermost hinge rod 31, so that the main body 1 of the communication terminal equipment and the extension component 3 are hinged together by the hinge shaft 131, two adjacent hinge rods 31 are hinged together by the convex shaft 32, and the base plate 2 and the extension component 3 are hinged together by the convex shaft 32.

[0045] In addition, a fan-shaped limiting groove 341 is provided on both the left and right end faces of the hinge rod 31. The limiting groove 341 is connected to the sleeve hole 34. A fan-shaped groove 222 is provided on the outer end face of the side seat 22. The fan-shaped groove 222 is connected to the shaft hole 221. A stop block 133 is embedded at the end of the hinge shaft 131. The stop block 133 extends into the limiting groove 341. A limiting block 321 is embedded at the end of the convex shaft 32. The limiting block 321 extends into the fan-shaped groove 222.

[0046] When the extension component 3 is in the retracted state, the stop block 133 abuts against the first end of the limiting groove 341 and the limiting block 321 abuts against the first end of the fan-shaped groove 222.

[0047] When the main body 1 of the communication terminal device is pulled outward to extend the extension component 3, the stop block 133 and the limiting block 321 rotate in the limiting groove 341 and the sector groove 222 respectively.

[0048] When the rotating stop 133 and the limiting block 321 abut against the ends of the limiting groove 341 and the sector groove 222 respectively, the extension component 3 reaches its maximum extension length. The maximum rotation angle of the stop 133 and the limiting block 321 is 120°, so that when the extension component 3 is extended, the maximum included angle between two adjacent hinge rods 31 is 120°. This allows the extension component 3 to retract by pushing the communication terminal equipment body 1 into the communication distribution cabinet 4 after it has been stretched to its longest state. This prevents the extension component 3 from failing to retract smoothly back to its original state due to the excessive angle between two adjacent hinge rods 31.

[0049] It is worth noting that handles 14 are fixed on both the left and right ends of the main body 1 of the communication terminal equipment, so that maintenance personnel can easily move the main body 1 of the communication terminal equipment into and out of the communication distribution cabinet 4 by holding the handles 14 on both sides.

[0050] In the above scheme, in order to keep the main body 1 of the communication terminal equipment suspended when it extends outward from the inside of the communication power distribution cabinet 4 so that maintenance personnel can perform maintenance work on the main body 1 of the communication terminal equipment, a number of hemispherical grooves 132 are provided on the end face of the fixed seat 13 at the root position of the hinge shaft 131. The grooves 132 are arranged in a ring with equal spacing around the hinge shaft 131. A number of positioning grooves 33 are also provided on the left and right end faces of the tail end of the hinge rod 31. The positioning grooves 33 are hemispherical and are arranged in a ring with equal spacing around the convex shaft 32.

[0051] The dimensions of the positioning groove 33 are the same as those of the groove 132. There are six grooves 132 and six positioning grooves 33, so that the angle formed by two adjacent grooves 132 and the hinge shaft 131 is 60°, and the angle formed by two adjacent positioning grooves 33 and the convex shaft 32 is 60°.

[0052] Specifically, a first mounting hole 223 is provided on the side end face of the side seat 22, and a second mounting hole 35 is provided on the side end face of the first end of the hinge rod 31. A steel ball 351 is fitted in both the first mounting hole 223 and the second mounting hole 35. A sealing bolt 353 is threaded to the opening of both the first mounting hole 223 and the second mounting hole 35. A spring 352 is provided between the sealing bolt 353 and the steel ball 351. The spring 352 is in a pre-compressed state.

[0053] Under the elastic force of spring 352, the steel ball 351 on the outermost hinge rod 31 extends into the groove 132, the steel balls 351 on the other hinge rods 31 extend into the positioning groove 33 of the adjacent hinge rods 31, and the steel ball 351 in the side seat 22 extends into the positioning groove 33 in the innermost hinge rod 31.

[0054] When the main body 1 of the communication terminal equipment drives the extension component 3 to extend and retract, the steel ball 351 can be inserted into the groove 132 and the positioning groove 33 under the action of the spring 352, respectively, so that the extension and retraction mode of the extension component 3 can be restricted by the steel ball 351. This allows the main body 1 of the communication terminal equipment to remain suspended under the action of the extension component 3, so that maintenance personnel can perform maintenance work on the main body 1 of the communication terminal equipment.

[0055] When maintenance personnel forcefully push or pull the main body 1 of the communication terminal equipment, the extension component 3 will cause the hinge rod 31 to rotate under the forced force of the maintenance personnel, so that the steel ball 351 is forced to be pushed and retracted into the first mounting hole 223 and the second mounting hole 35, thereby allowing the extension component 3 to approach the base plate 2 or extend outward from the communication distribution cabinet 4 under the forced force of the maintenance personnel.

[0056] The working principle of the communication device of the Internet of Things terminal of the present invention is as follows:

[0057] When maintenance personnel need to perform maintenance work on the main body 1 of the communication terminal equipment, they can first open the communication power distribution cabinet 4 and then remove the bolts 12 with handles from the boss 21 at both ends of the top and bottom of the main body 1 of the communication terminal equipment, so that the main body 1 of the communication terminal equipment is separated from the base plate 2.

[0058] Then the maintenance personnel hold the handles 14 on both sides of the main body 1 of the communication terminal equipment and pull the main body 1 of the communication terminal equipment outward, so that the main body 1 of the communication terminal equipment drives the extension component 3 to extend. At this time, the two adjacent hinge rods 31 rotate relative to each other. Under the action of multiple hinge rods 31, the extension component 3 is extended and the main body 1 of the communication terminal equipment extends outward from inside the communication distribution cabinet 4.

[0059] While the hinge rod 31 is being pulled by maintenance personnel, the steel ball 351 installed in the side seat 22 and the extension assembly 3 will retract into the first mounting hole 223 and the second mounting hole 35 respectively due to compression. As the hinge rod 31 rotates, the steel ball 351 can extend into the groove 132 and the positioning groove 33 again, thereby restricting the shape of the extension assembly 3 and keeping the main body 1 of the communication terminal equipment suspended so that maintenance personnel can perform maintenance.

[0060] Finally, when the maintenance personnel pull the main body 1 of the communication terminal equipment outward to extend the extension component 3, the stop block 133 and the limiting block 321 rotate in the limiting groove 341 and the sector groove 222 respectively. When the rotating stop block 133 and the limiting block 321 abut against the end of the limiting groove 341 and the sector groove 222 respectively, the extension component 3 reaches the maximum extension length, preventing the extension component 3 from failing to retract smoothly back to its original state due to the excessive angle between two adjacent hinge rods 31.

[0061] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
