[0001] The present invention relates to the technical field of communications, and particularly to a wireless communication gateway based on digital remote communication in a refrigerated warehouse.

Background Art

[0002] A gateway device is used to connect a network device to a network. It is a device that connects networks and is also called a protocol converter. A gateway is a computer system or device that is responsible for converting between two systems with different communication protocols, data formats, or languages, and even different architectures. A gateway is a translator. Different from a bridge that simply transmits information, it repackages the received information according to the needs of the destination system. As a household gateway device, a router is common, but an industrial gateway device can bridge networks between different systems according to different communication protocols.

[0003] When a conventional gateway device is used in a refrigerated warehouse, since there are goods stored in the refrigerated warehouse, workers need to frequently take in and out the goods. In the process of taking in and out the goods, the connection cable or the gateway casing may be touched, and loosening may occur between the female terminal and the male terminal. When the gateway device is used for a long time, poor contact is also likely to occur between the female terminal and the male terminal, and the worker needs to unplug the female terminal once and insert it again into the male terminal. However, in order not to affect the workers' taking in and out of the goods, the gateway device in the refrigerated warehouse is usually installed at a high position, and it is very inconvenient and difficult for the worker to unplug and insert the female terminal.

[0016] By employing the above technical means, the advantageous effects of the present invention include: 1. If a contact failure occurs in the female terminal after prolonged use, the electric push rod, stop plate, second push block, inner cylinder, projection, and swash plate are controlled via an external controller to extend the corresponding electric push rod, moving the stop plate and second push block away from the gateway casing. The inner cylinder then moves the swash plate and female terminal together with the second push block via the projection and locking groove, thereby dislodging the female terminal. After that, the electric push rod returns to its original position, returning the stop plate, second push block, inner cylinder, projection, swash plate, and female terminal to their original positions, completing the insertion and removal of the female terminal. This eliminates the need for manual operation by automating the insertion and removal of the female terminal, as in many cases, contact failure problems can be solved by inserting and removing the female terminal.

[0017] 2. When the female terminal is inserted into the gateway casing, pulling the first push block outward pulls the inner cylinder outward, then pushing the swashplate engages the projection with the locking groove inside the inner cylinder, restricting the female terminal. Releasing the first push block and allowing the inner cylinder to return to its original position due to the action of the first spring ensures that the female terminal is securely inserted. The first spring then inserts the female terminal into the gateway casing, reducing the possibility of the female terminal becoming loose. At the same time, even if the connecting cable is accidentally pulled during cargo handling, the female terminal will not become loose and fall out. Even if the female terminal is pulled, the action of the first spring will allow it to automatically return to its original position, eliminating the need for workers to reinsert the female terminal.

[0018] 3. With the arc-shaped block, notch, and third bolt, after loosening the second bolt, the corresponding arc-shaped block can be moved. When it is necessary to install the gateway casing in a corner, the installation of the gateway casing becomes easier by moving the arc-shaped block along the fixing ring at a certain angle. After moving the arc-shaped block, the arc-shaped block can be fixed in any position on the fixing ring after movement by tightening the second bolt, making the operation simple and convenient. When the gateway casing is fixed to a shelf, or when there are objects that can be used for auxiliary fixing around it, the arc-shaped block can be rotated at a certain angle to position the shelf fixing rod or other auxiliary fixing object within the notch, and then the third bolt can be tightened to fix it. This increases the methods for fixing the gateway casing, and the gateway casing can be fixed more firmly based on fixing with a vertical plate.

[0019] 4. The arc-shaped ring is connected to the fixing ring via a fixing block, a round hole, a first bolt, and a fixing groove. In the event of a malfunction inside the gateway device, a worker can remove the arc-shaped ring by loosening the first bolt and dismantle the gateway casing. Similarly, if it is necessary to remove the arc-shaped block, the arc-shaped ring can be removed to remove the arc-shaped block, making the operation simple.

[0020] 5. The winding rod, second spring, arc-shaped block, and notch allow the connection cable to be wound around the notch if it is too long. The arc-shaped block remains fixed during use, so even if the connection cable is accidentally pulled when no cargo is being transported after being wound around the notch, the female terminal will not be affected. The connection cable is wound around the notch first, then around the winding rod. When the connection cable is pulled, the winding rod moves, the second spring acts as a buffer first, protecting the connection cable. Since the connection cable wound around the notch does not move, it prevents the female terminal from loosening and makes the operation of the gateway device more stable.

Modes for Carrying Out the Invention

[0023] Hereinafter, specific embodiments of the present invention will be described in detail while referring to the accompanying drawings and examples. The following examples are used to explain the present invention, but do not limit the scope of the present invention.

[0024] The attachment method, connection method or installation method of each of the above components of the wireless communication gateway based on digital remote communication in the refrigerator provided by the present invention is a general mechanical method. The specific structure, model and coefficient index of each component are unique technologies, and as long as the advantageous effects can be achieved, they are feasible. Therefore, the detailed description thereof is omitted here.

[0025] In the wireless communication gateway based on digitized telecommunications for refrigerated warehouses provided in this invention, unless explicitly stated otherwise, directions such as "up," "down," "left," "right," "front," "back," "inside," "outside," "vertical," and "horizontal" represent the orientation of the components under normal use conditions, or are merely common names understood by those skilled in the art, and should not be understood as limitations on the components. Furthermore, numerical nouns such as "first," "second," and "third" do not indicate specific quantities or orders, but are used solely to distinguish names. The terms "equip," "include," or any other variant are intended to cover non-exclusive inclusion, thereby including not only these elements but also other elements not explicitly mentioned, or elements inherent to such a process, method, article, or apparatus. [Examples]

[0026] As shown in Figures 1 to 8, a wireless communication gateway based on digital remote communication in a refrigerated warehouse comprises a gateway casing 1, a male terminal, a female terminal 2, and a connecting cable 3. The male terminal is provided on the gateway casing 1, one end of the female terminal 2 is connected to the connecting cable 3 and the other end is fitted to the male terminal, an outer cylinder 4 is provided on the outside of the male terminal, an inner cylinder 5 is slidably mounted on the inner wall of the outer cylinder 4, the female terminal 2 is connected to the inner wall of the inner cylinder 5, a second push block 14 is provided at the bottom of the outer cylinder 4 and penetrates the side wall of the outer cylinder 4, a groove for moving the second push block 14 is provided on the side wall of the outer cylinder 4, the top of the second push block 14 is connected and fixed to the outer wall of the inner cylinder 5, a stop plate 13 is connected and fixed to one side of the bottom of the second push block 14, an electric push rod 12 is provided on the side of the stop plate 13 closer to the gateway casing 1, one end of the electric push rod 12 is connected and fixed to the gateway casing 1 and the other end is connected and fixed to the stop plate 13. A first spring 9 is provided at the end of the inner cylinder 5 closest to the gateway casing 1, one end of the first spring 9 is connected and fixed to the inner cylinder 5, and the other end is connected and fixed to the outer wall of the gateway casing 1, locking grooves 35 are drilled on both sides of the inner cylinder 5, swash plates 7 are provided on both sides of the female terminal 2, one end of the swash plate 7 is connected and fixed to the female terminal 2, a projection 8 is provided in the center of the swash plate 7, the projection 8 can be locked into the locking groove 35, a first push block 11 is also provided on one side of the inner cylinder 5, a corresponding first push slot 10 is drilled on one side of the outer cylinder 4, a limiting block 6 is provided on the outer wall of the inner cylinder 5, and a corresponding limiting groove is drilled on the side wall of the outer cylinder 4.When the female terminal 2 is inserted into the gateway casing 1, the first push block 11 is pulled outward, which pulls out the inner cylinder 5. Then the swash plate 7 is pushed, which engages the projection 8 with the locking groove 35 inside the inner cylinder 5, restricting the female terminal 2. The first push block 11 is released, and the inner cylinder 5 returns to its original position due to the action of the first spring 9, ensuring that the female terminal 2 is firmly inserted. The first spring 9 pulls the female terminal 2 toward the gateway casing 1, causing the female terminal 2 to be inserted into the gateway casing 1, reducing the possibility of the female terminal 2 becoming loose. At the same time, even if the connecting cable 3 is accidentally pulled during cargo transport, the female terminal 2 will not become loose and come out. Even if the female terminal 2 is pulled, the action of the first spring 9 will allow it to automatically return to its original position, eliminating the need for workers to reinsert the female terminal 2. If a contact problem occurs in the female terminal 2 after prolonged use, the corresponding electric push rod 12 is controlled via an external controller to extend, moving the stop plate 13, inner cylinder 5, and female terminal 2, and removing the female terminal. After that, the electric push rod 12 returns to its original position, returning the female terminal 2 to its original position, completing the insertion and removal of the female terminal 2, eliminating the need for manual operation by the worker. In many cases, contact problems can be solved by inserting and removing the female terminal 2, so automating the insertion and removal of the female terminal 2 saves the worker's time.

[0027] A restricting block 6 is provided on the outer wall of the inner cylinder 5. The restricting block 6 restricts the inner cylinder 5 so that it can move only along the axial direction of the inner cylinder 5 and the outer cylinder 4. This allows the female terminal 2 to be aligned with the male terminal when inserting or removing it, thereby preventing damage to the female terminal 2 or the male terminal due to misalignment during insertion.

[0028] As a preferred technical means of the present invention, a horizontal rod 15 is connected and fixed to the bottom of the second push block 14, a vertical rod 16 is connected and fixed to the end of the horizontal rod 15 away from the second push block 14, a retainer ring 17 is provided at the top of the vertical rod 16, the center of the retainer ring 17 and the center of the female terminal 2 are on the same horizontal line, and the connecting cable 3 passes through the retainer ring 17. The retainer ring 17 lifts the connecting cable 3, preventing the connection between the connecting cable 3 and the female terminal 2 from being subjected to excessive external force, thereby avoiding damage to the connection between the connecting cable 3 and the female terminal 2, extending the lifespan of the connecting cable 3 and the female terminal 2, and preventing the mating between the female terminal 2 and the male terminal from loosening and causing poor contact, which would affect the normal use of the gateway, as the connecting cable 3 pulls the female terminal 2 downward under the action of gravity. When the electric push rod 12 pushes the stop plate 13, the horizontal rod 15 and vertical rod 16 also move in response. The vertical rod 16 moves the retainer ring 17 via the vertical groove 18 and clamping rod 19. The retainer ring 17 supports the connecting cable 3 during movement, preventing the female terminal 2 from getting caught on the connecting cable 3 during its movement or being pulled downwards for other reasons, which would cause the angle of the female terminal 2 to tilt and prevent accurate insertion into the male terminal, thus preventing insertion failure of the female terminal 2.

[0029] As a preferred technical means of the present invention, the retainer ring 17 is composed of two semi-rings, with a clamping rod 19 connected and fixed to the bottom of the semi-rings, and a vertical groove 18 drilled vertically at the top of the vertical rod 16, into which the two clamping rods 19 are inserted. When attaching or detaching, it is only necessary to remove the retainer ring 17 and the clamping rods 19 from the vertical groove 18, making the operation simple and convenient.

[0030] As a preferred technical means of the present invention, a fixing ring 20 is connected to the outer wall of the gateway casing 1, the inside of the fixing ring 20 is connected and fixed to the outer wall of the rear end of the gateway casing 1, an annular groove 22 is drilled in the top of the fixing ring 20, an arc-shaped block 27 is attached to the outside of the fixing ring 20, a through groove 28 is drilled through the arc-shaped block 27, the fixing ring 20 passes through the through groove 28 and is slidably connected to the inner wall of the through groove 28, a second bolt 29 is screwed into the upper part of the arc-shaped block 27, and the bottom of the second bolt 29 abuts against the top of the fixing ring 20. The arc-shaped block 27 is slidably attached to the fixing ring 20. After loosening the second bolt 29, the corresponding arc-shaped block 27 can be moved. When the gateway casing 1 needs to be installed in a corner, the installation of the gateway casing 1 becomes easier by moving the arc-shaped block 27 along the fixing ring 20 at a certain angle. After moving the arc-shaped block 27, the arc-shaped block 27 can be fixed in any position on the fixing ring 20 after the move by tightening the second bolt 29. The operation is simple and convenient. When the gateway casing 1 is to be fixed to a shelf, or when there are objects around it that can be used for auxiliary fixing, the arc-shaped block 27 can be rotated at a certain angle to position the shelf fixing rod or other auxiliary fixing object within the notch 31, and then the third bolt 32 can be tightened to fix it. This increases the methods for fixing the gateway casing 1, and allows for more secure fixing of the gateway casing 1 based on the fixing by the vertical plate 34.

[0031] As a preferred technical means of the present invention, an arc-shaped ring 21 is provided on one side of the fixing ring 20, the fixing ring 20 and the arc-shaped ring 21 form a single ring, the arc-shaped ring 21 is located at the front end of the gateway casing 1, fixing blocks 24 are provided at both ends of the arc-shaped ring 21, round holes 25 are drilled vertically in the fixing blocks 24, fixing grooves 23 are drilled at both ends of the fixing ring 20, first bolts 26 are provided above the fixing grooves 23, the fixing blocks 24 are inserted into the fixing grooves 23, and the first bolts 26 can pass through the round holes 25. The arc-shaped ring 21 is connected to the fixing ring 20 via the fixing blocks 24, round holes 25, first bolts 26 and fixing grooves 23, and in the event of a malfunction inside the gateway device, a worker can remove the arc-shaped ring 21 by loosening the first bolts 26 and dismantle the gateway casing 1. If it is necessary to remove the arc-shaped block 27, the operation is simple because it can be removed by similarly removing the arc-shaped ring 21.

[0032] As a preferred technical means of the present invention, a sliding groove is drilled horizontally on the side of the arc-shaped block 27 away from the gateway casing 1, a winding rod 30 is provided in the sliding groove, one end of the winding rod 30 is slidably connected to the inner wall of the sliding groove, and a retaining piece is provided at the other end, a second spring 33 is provided in the sliding groove, one end of the second spring 33 is connected and fixed to the winding rod 30, and the other end is connected and fixed to the inner wall of the sliding groove. There are many goods and shelves in the refrigerated warehouse, and the connecting cable 3 is easily pulled when transporting goods, so by winding the excess portion of the connecting cable 3 around the winding rod 30, the connecting cable 3 can be kept in a moderately taut state, preventing the connecting cable 3 from becoming loose and hanging in the air, and reducing the possibility of workers touching the connecting cable 3.

[0033] As a preferred technical means of the present invention, notches 31 are drilled on both the left and right sides along the horizontal direction of the arc-shaped block 27, screw holes are drilled horizontally in the side walls of the notches 31, and a third bolt 32 is provided in the screw holes. If the connecting cable 3 is too long, the connecting cable 3 can be wrapped around the notches 31, and since the arc-shaped block 27 is fixed in place during use, even if the connecting cable 3 is accidentally pulled when no cargo is being transported after being wrapped around the notches 31, the female terminal 2 will not be affected. The connecting cable 3 is first wrapped around the notches 31 and then around the winding rod 30, and when the connecting cable 3 is pulled, the winding rod 30 moves, the second spring 33 acts as a buffer first, protecting the connecting cable 3, and since the connecting cable 3 wrapped around the notches 31 does not move, the female terminal 2 does not loosen, and the operation of the gateway device becomes more stable.

[0034] In a preferred technical means of the present invention, a vertical plate 34 is connected and fixed to the bottom of the fixing ring 20, the vertical plate 34 is located at the rear end of the gateway casing 1, and fixing holes are drilled in the vertical plate 34.

[0035] As shown in Figures 1 to 8, when using the gateway casing 1, first attach it to the designated position in the cold storage warehouse. If screws can be fastened to the wall of the cold storage warehouse, the gateway casing 1 can be fixed using the bolt holes on the vertical plate 34. If screws cannot be fastened to the wall of the cold storage warehouse, the gateway casing 1 can be hung and fixed to the shelf of the cold storage warehouse using the fixing rings 20 and vertical plate 34. Multiple sets of fixing rings 20 and vertical plates 34 are provided on the gateway casing 1, and the lowest vertical plate 34 is flush with the bottom of the gateway casing 1, increasing stability when the vertical plate 34 is placed on the ground.

[0036] After installing the gateway casing 1, the retainer ring 17 is lifted upward to separate the two corresponding clamping rods 19. The connecting cable 3 and female terminal 2 are then passed through the retainer ring 17, and the clamping rods 19 are inserted into the vertical grooves 18 to restrict the connecting cable 3. Subsequently, the female terminal 2 is inserted into the gateway casing 1. The retainer ring 17 lifts the connecting cable 3, preventing excessive external force from being applied to the connection between the connecting cable 3 and the female terminal 2, thus avoiding damage to the connection and extending the lifespan of the connecting cable 3 and the female terminal 2. Furthermore, the connection cable 3 pulling the female terminal 2 downward under the influence of gravity prevents loosening of the mating between the female terminal 2 and the male terminal, preventing poor contact and thus preventing the normal use of the gateway.

[0037] The gateway device can be used normally after the worker inserts the female terminal 2 into the gateway casing 1 and then wraps the remaining portion of the connecting cable 3 around the winding rod 30.

[0038] The inner cylinder 5 is located inside the outer cylinder 4. When a worker inserts the female terminal 2 into the gateway casing 1, the first push block 11 is pulled outward, pulling the inner cylinder 5 outward. Then, the swash plate 7 is pushed, engaging the projection 8 with the locking groove 35 inside the inner cylinder 5, restricting the female terminal 2. The first push block 11 is then released, and the inner cylinder 5 returns to its original position due to the action of the first spring 9, ensuring that the female terminal 2 is securely inserted. The first spring 9 pulls the female terminal 2 toward the gateway casing 1, causing the female terminal 2 to be inserted into the gateway casing 1, reducing the possibility of the female terminal 2 becoming loose. At the same time, even if the connecting cable 3 is accidentally pulled during cargo transport, the female terminal 2 will not become loose and fall out. Even if the female terminal 2 is pulled, the action of the first spring 9 will allow it to automatically return to its original position, eliminating the need for the worker to reinsert the female terminal 2.

[0039] In a refrigerated warehouse, there are many goods and shelves, and the connecting cable 3 is easily pulled when goods are transported. By wrapping the excess portion of the connecting cable 3 around the winding rod 30, the connecting cable 3 is kept at a moderate tension, preventing it from becoming loose and hanging in the air, and reducing the possibility of workers touching the connecting cable 3. If a worker accidentally touches and pulls the connecting cable 3, the winding rod 30 moves horizontally, the second spring 33 provides a cushioning effect, further reducing the possibility of the female terminal 2 loosening and improving the stability of the gateway device during use.

[0040] If a contact failure occurs in the female terminal 2 after prolonged use, the corresponding electric push rod 12 is controlled via an external controller to extend, moving the stop plate 13 and the second push block 14 away from the gateway casing 1. The inner cylinder 5 moves the swash plate 7 and the female terminal 2 together with the second push block 14 via the projection 8 and locking groove 35, thereby removing the female terminal 2. After that, the electric push rod 12 returns to its original position, returning the stop plate 13, the second push block 14, the inner cylinder 5, the projection 8, the swash plate 7, and the female terminal 2 to their original positions, completing the insertion and removal of the female terminal 2. This eliminates the need for manual operation by the operator. In many cases, contact failure problems can be solved by inserting and removing the female terminal 2, so automating the insertion and removal of the female terminal 2 saves the operator's time.

[0041] A restricting block 6 is provided on the outer wall of the inner cylinder 5. The restricting block 6 restricts the inner cylinder 5 so that it can move only along the axial direction of the inner cylinder 5 and the outer cylinder 4. This allows the female terminal 2 to be aligned with the male terminal when inserting or removing it, thereby preventing damage to the female terminal 2 or the male terminal due to misalignment during insertion.

[0042] When the electric push rod 12 pushes the stop plate 13, the horizontal rod 15 and vertical rod 16 also move in response. The vertical rod 16 moves the retainer ring 17 via the vertical groove 18 and clamping rod 19. The retainer ring 17 supports the connecting cable 3 during movement, preventing the connecting cable 3 from getting caught during the movement of the female terminal 2, or the female terminal 2 from being pulled downwards for other reasons, which can cause the angle of the female terminal 2 to tilt and prevent accurate insertion into the male terminal. This not only prevents insertion failure of the female terminal 2 but also prevents damage to the female terminal 2 or the male terminal.

[0043] The retainer ring 17 is inserted into the vertical groove 18 via the clamping rod 19, and when attaching or detaching it, all that is required is to remove the retainer ring 17 and the clamping rod 19 from the vertical groove 18, making the operation simple and convenient.

[0044] The arc-shaped block 27 is slidably attached to the fixing ring 20. After loosening the second bolt 29, the corresponding arc-shaped block 27 can be moved. When the gateway casing 1 needs to be installed in a corner, the installation of the gateway casing 1 becomes easier by moving the arc-shaped block 27 along the fixing ring 20 at a certain angle. After moving the arc-shaped block 27, the arc-shaped block 27 can be fixed in any position on the fixing ring 20 after the move by tightening the second bolt 29. The operation is simple and convenient. When the gateway casing 1 is to be fixed to a shelf, or when there are objects around it that can be used for auxiliary fixing, the arc-shaped block 27 can be rotated at a certain angle to position the shelf fixing rod or other auxiliary fixing object within the notch 31, and then the third bolt 32 can be tightened to fix it. This increases the methods for fixing the gateway casing 1, and allows for more secure fixing of the gateway casing 1 based on the fixing by the vertical plate 34.

[0045] The arc-shaped ring 21 is connected to the fixing ring 20 via the fixing block 24, the round hole 25, the first bolt 26, and the fixing groove 23. If a malfunction occurs inside the gateway device, a worker can remove the arc-shaped ring 21 by loosening the first bolt 26 and dismantle the gateway casing 1. Similarly, if it is necessary to remove the arc-shaped block 27, the arc-shaped block 27 can be removed by removing the arc-shaped ring 21, making the operation simple.

[0046] If the connection cable 3 is too long, it can be wrapped around the notch 31. Since the arc-shaped block 27 is fixed in place during use, even if the connection cable 3 is accidentally pulled when no cargo is being transported after being wrapped around the notch 31, the female terminal 2 will not be affected. The connection cable 3 is first wrapped around the notch 31 and then around the winding rod 30. When the connection cable 3 is pulled, the winding rod 30 moves, and the second spring 33 acts as a buffer first, protecting the connection cable 3. Since the connection cable 3 wrapped around the notch 31 does not move, the female terminal 2 does not loosen, and the operation of the gateway device becomes more stable.

[0047] The foregoing describes only one preferred embodiment of the present invention. Those skilled in the art should note that various improvements and modifications can be made without departing from the technical principles of the present invention, and such improvements and modifications are also considered to be within the scope of protection of the present invention.
