Description

[Technical Field]

[0001] The present invention relates to the technical field of communications, and in particular to a wireless communication gateway based on digitalized telecommunications in cold storage warehouses. [Background technology]

[0002] Gateway devices, also known as protocol converters, are used to connect network devices to other networks and to connect networks to one another. A gateway is a computer system or device that converts between two systems with different communication protocols, data formats, languages, and even architectures. Unlike a bridge that simply transmits information, a gateway is a translator; it repackages the received information to meet the needs of the destination system. While routers are common as home gateway devices, industrial gateway devices can bridge networks between different systems using different communication protocols.

[0003] When conventional gateway devices are used in refrigerated warehouses, workers frequently move goods in and out of the warehouse, which can cause loosening between the female and male terminals by touching the connecting cable or gateway casing during the process. Prolonged use of the gateway device can also lead to poor contact between the female and male terminals, requiring workers to unplug the female terminal and reinsert it into the male terminal. However, to avoid interfering with workers' ability to load and unload goods, gateway devices in refrigerated warehouses are typically installed at a high position, making it extremely inconvenient and difficult for workers to plug and unplug the female terminal.

[0009] Preferably, the retainer ring is made up of two half rings, with clamping rods connected and fixed to the bottom of the half rings, and vertical grooves drilled vertically at the top of the vertical rods, with the two clamping rods inserted into the vertical grooves.

[0010] Preferably, a fixed ring is connected to the outer wall of the gateway casing, the inside of the fixed ring is connected and fixed to the outer wall of the rear end of the gateway casing, an annular groove is drilled at the top of the fixed ring, an arc-shaped block is attached to the outside of the fixed ring, a through-groove is formed on the arc-shaped block, the fixed ring passes through the through-groove and is slidably connected to the inner wall of the through-groove, a second bolt is screwed onto the top of the arc-shaped block, and the bottom of the second bolt abuts against the top of the fixed ring.

[0011] Preferably, an arc-shaped ring is provided on one side of the fixed ring, and the fixed ring and the arc-shaped ring form a ring. The arc-shaped ring is located at the front end of the gateway casing. Fixed blocks are provided on both ends of the arc-shaped ring, and circular holes are drilled longitudinally in the fixed blocks. Fixed grooves are drilled on both ends of the fixed ring. A first bolt is provided above the fixed groove, and the fixed block is inserted into the fixed groove, and the first bolt can pass through the circular holes.

[0012] Preferably, a sliding groove is drilled horizontally on the side of the arc-shaped block away from the gateway casing, a winding rod is provided in the sliding groove, one end of the winding rod is slidably connected to the inner wall of the sliding groove, and a stop piece is provided at the other end.

[0015] Preferably, a standing plate is connected and fixed to the bottom of the fixed ring, the standing plate being located at the rear end of the gateway casing, and a fixing hole being drilled in the standing plate. [Effects of the Invention]

[0016] By adopting the above technical means, the present invention has the following advantageous effects: 1. If the electric push rod, stop plate, second push block, inner cylinder, protrusion, and swash plate cause poor contact of the female terminal after long-term use, the corresponding electric push rod can be extended via an external controller, causing the stop plate and second push block to move away from the gateway casing, and the inner cylinder, via its protrusion and locking groove, moves the swash plate and female terminal together with the second push block, thereby extracting the female terminal. The electric push rod then returns to its original position, returning the stop plate, second push block, inner cylinder, protrusion, swash plate, and female terminal to their original positions, completing the insertion and extraction of the female terminal, eliminating the need for operator intervention. In many cases, poor contact issues can be resolved by simply inserting or removing the female terminal, thereby saving operator time by automating the insertion and extraction of the female terminal.

[0017] 2. When the female terminal is inserted into the gateway casing, the first pushing block is pulled outward to pull the inner cylinder outward, and then the swash plate is pressed to lock the protrusion into the locking groove in the inner cylinder, restricting the female terminal. The first pushing block is released, and the inner cylinder is returned to its original position by the action of the first spring, ensuring that the female terminal is inserted firmly. The first spring inserts the female terminal into the gateway casing, reducing the possibility of the female terminal coming loose. At the same time, even if the connecting cable is accidentally pulled when transporting luggage, the female terminal will not come loose and be pulled out. Even if the female terminal is pulled, it will automatically return to its original position by the action of the first spring, eliminating the need for workers to reinsert the female terminal.

[0018] 3. The arc-shaped block, notch, and third bolt allow the corresponding arc-shaped block to be moved after loosening the second bolt. When the gateway casing needs to be installed at a corner, the arc-shaped block can be moved at a certain angle along the fixing ring, making installation easier. After moving the arc-shaped block, the second bolt can be tightened to fix the arc-shaped block in any position on the fixing ring, making the operation simple and convenient. When the gateway casing is to be fixed to a shelf or there are surrounding objects that can be fixed, the arc-shaped block can be rotated at a certain angle, the shelf fixing rod or other auxiliary fixing object can be positioned in the notch, and the third bolt can then be tightened to fix it. This increases the number of ways to fix the gateway casing and, compared to fixing using a vertical board, can make the gateway casing more firmly fixed.

[0019] 4. The arc-shaped ring is connected to the fixed ring via the fixed block, round hole, first bolt and fixing groove. If a malfunction occurs inside the gateway device, workers can remove the arc-shaped ring by loosening the first bolt and dismantle the gateway casing. If the arc-shaped block needs to be removed, it can be removed by similarly removing the arc-shaped ring, 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 wound around the notch and accidentally pulled when no cargo is being transported, the female terminal will not be affected. The connection cable is wound around the notch first, and then around the winding rod. When the connection cable is pulled, the winding rod moves and the second spring first provides a buffering effect to protect the connection cable. The connection cable wound around the notch does not move, preventing the female terminal from loosening and making the operation of the gateway device more stable.

DETAILED DESCRIPTION OF THE INVENTION

[0023] Specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention but are not intended to limit the scope of the present invention.

[0024] The mounting, connection or installation method of each of the above components of the wireless communication gateway based on digitalized remote communication in a cold storage warehouse provided by the present invention is a general mechanical method, and the specific structure, model and coefficient index of each component are unique technologies, which can be implemented as long as they can achieve their advantageous effects, so detailed description thereof will be omitted here.

[0025] In the wireless communication gateway based on digitalized remote communication in a cold storage warehouse provided by the present invention, unless explicitly stated to the contrary, the orientations indicated by "up," "down," "left," "right," "front," "back," "inside," "outside," "vertical," "horizontal," etc., represent the orientation of components in normal use or are merely common names understood by those skilled in the art and should not be construed as limitations on the components. Furthermore, the use of numerical nouns such as "first," "second," and "third" does not indicate a specific quantity or order, but is used only to distinguish the names. The terms "comprise," "include," and any other variants thereof are intended to cover a non-exclusive inclusion, whereby a process, method, article, or device comprising a series of elements includes not only those elements but also other elements not expressly listed or inherent elements of such process, method, article, or device. [Example]

[0026] As shown in Figures 1 to 8, this is a wireless communication gateway based on digitalized remote communication in a refrigerated warehouse, comprising a gateway casing 1, a male terminal, a female terminal 2, and a connecting cable 3, wherein the male terminal is mounted 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 with the male terminal, an outer tube 4 is mounted on the outside of the male terminal, an inner tube 5 is slidably mounted on the inner wall of the outer tube 4, the female terminal 2 is connected to the inner wall of the inner tube 5, a second pushing block 14 is mounted at the bottom of the outer tube 4 and penetrates the side wall of the outer tube 4, a groove is formed on the side wall of the outer tube 4 for moving the second pushing block 14, the top of the second pushing block 14 is connected and fixed to the outer wall of the inner tube 5, a stop plate 13 is connected and fixed to one side of the bottom of the second pushing block 14, and an electric push rod 12 is mounted 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 close 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. Slant plates 7 are provided on both sides of the female terminal 2, one end of the slanted plates 7 is connected and fixed to the female terminal 2. A protrusion 8 is provided in the center of the slanted plate 7, and the protrusion 8 can be locked in the locking groove 35. A first pushing block 11 is also provided on one side of the inner cylinder 5. A corresponding first pushing 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 pushing block 11 is pulled outward, drawing the inner cylinder 5 outward, and then the swash plate 7 is pushed, causing the protrusion 8 to engage with the locking groove 35 in the inner cylinder 5, restricting the female terminal 2. The first pushing block 11 is released, and the inner cylinder 5 is returned to its original position by the action of the first spring 9, firmly inserting the female terminal 2. The first spring 9 pulls the female terminal 2 toward the gateway casing 1, inserting the female terminal 2 into the gateway casing 1 and reducing the possibility of the female terminal 2 becoming loose. At the same time, even if the connection cable 3 is accidentally pulled when transporting luggage, the female terminal 2 can be prevented from becoming loose and coming off. Even if the female terminal 2 is pulled, it can be automatically returned to its original position by the action of the first spring 9, eliminating the need for an operator to reinsert the female terminal 2. If poor contact occurs in the female terminal 2 after long-term 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 to remove the female terminal. The electric push rod 12 is then returned to its original position, returning the female terminal 2 to its original position and completing the insertion and removal of the female terminal 2, eliminating the need for operator operation. In many cases, poor contact issues can be resolved by simply inserting or removing the female terminal 2, so automating the insertion and removal of the female terminal 2 saves operator time.

[0027] A limiting block 6 is provided on the outer wall of the inner tube 5, and the limiting block 6 can limit the inner tube 5 so that it can move only along the axial direction of the inner tube 5 and the outer tube 4. This allows the female terminal 2 to be aligned with the male terminal when inserted or removed, thereby preventing damage to the female terminal 2 or the male terminal due to misalignment when the female terminal 2 is inserted.

[0028] As a preferred technical measure of the present invention, a horizontal rod 15 is connected and fixed to the bottom of second pushing block 14, a vertical rod 16 is connected and fixed to the end of horizontal rod 15 away from second pushing block 14, a retaining ring 17 is provided on the top of vertical rod 16, the centers of retaining ring 17 and female terminal 2 are on the same horizontal line, and connection cable 3 passes through retaining ring 17. Retaining ring 17 raises connection cable 3, preventing the connection between connection cable 3 and female terminal 2 from being subjected to excessive external force, avoiding damage to the connection between connection cable 3 and female terminal 2 and extending the life of connection cable 3 and female terminal 2. It also prevents connection cable 3 from pulling female terminal 2 downward under the action of gravity, which could loosen the engagement between female terminal 2 and male terminal, causing poor contact and affecting normal use of the gateway. When the electric push rod 12 pushes the stop plate 13, the horizontal rod 15 and vertical rod 16 also move, and the vertical rod 16 moves the retainer ring 17 via the vertical groove 18 and the clamping rod 19, and the retainer ring 17 supports the connection cable 3 as it moves, and prevents the angle of the female terminal 2 from being tilted and preventing accurate insertion into the male terminal, which would otherwise occur if the connection cable 3 gets caught while the female terminal 2 is moving or the female terminal 2 is pulled downward for other reasons, preventing failure in insertion of the female terminal 2.

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

[0030] As a preferred technical measure of the present invention, a fixed ring 20 is connected to the outer wall of the gateway casing 1, the inside of which is connected and fixed to the outer wall of the rear end of the gateway casing 1, an annular groove 22 is drilled at the top of the fixed ring 20, an arc-shaped block 27 is attached to the outside of the fixed ring 20, a through-groove 28 is formed on the arc-shaped block 27, the fixed 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 top of the arc-shaped block 27, and the bottom of the second bolt 29 abuts against the top of the fixed ring 20. The arc-shaped blocks 27 are slidably mounted on the fixed rings 20, and the corresponding arc-shaped blocks 27 can be moved after loosening the second bolts 29. When the gateway casing 1 needs to be installed at a corner, the arc-shaped blocks 27 can be moved at a certain angle along the fixed rings 20, facilitating installation of the gateway casing 1. After moving the arc-shaped blocks 27, the second bolts 29 can be tightened to fix the arc-shaped blocks 27 at any desired position on the fixed rings 20, making the operation simple and convenient. When the gateway casing 1 is to be fixed to a shelf or there is an object that can be fixed nearby, the arc-shaped blocks 27 can be rotated at a certain angle to position the shelf's fixing rod or other auxiliary fixing object into the notches 31, and then the third bolts 32 can be tightened to fix the gateway casing 1. This increases the number of ways to fix the gateway casing 1, and, in addition to being fixed by the uprights 34, the gateway casing 1 can be fixed more firmly.

[0031] In a preferred technical means of the present invention, a circular ring 21 is provided on one side of the fixed ring 20, and the fixed ring 20 and the circular ring 21 form a single ring. The circular ring 21 is located at the front end of the gateway casing 1. Fixed blocks 24 are provided on both ends of the circular ring 21, and circular holes 25 are drilled longitudinally in the fixed blocks 24. Fixed grooves 23 are drilled on both ends of the fixed ring 20. A first bolt 26 is provided above the fixed groove 23, and the fixed block 24 is inserted into the fixed groove 23, with the first bolt 26 passing through the circular hole 25. The circular ring 21 is connected to the fixed ring 20 via the fixed block 24, the circular hole 25, the first bolt 26, and the fixed groove 23. In the event of a malfunction within the gateway device, workers can loosen the first bolt 26 to remove the circular ring 21 and dismantle the gateway casing 1. When it is necessary to remove the arc-shaped block 27, the arc-shaped ring 21 is removed in the same manner, so that the arc-shaped block 27 can be removed, and the operation is simple.

[0032] As a preferred technical means of the present invention, a sliding groove is drilled horizontally on the side of arc-shaped block 27 away from gateway casing 1, a winding rod 30 is provided in the sliding groove, one end of winding rod 30 is slidably connected to the inner wall of the sliding groove and a stop piece is provided at the other end, and a second spring 33 is provided in the sliding groove, one end of second spring 33 is connected and fixed to winding rod 30 and the other end is connected and fixed to the inner wall of the sliding groove. Since there are many packages and shelves in a refrigerated warehouse and connecting cable 3 is likely to be pulled when the packages are transported, the excess part of connecting cable 3 can be wound around winding rod 30 to keep connecting cable 3 at an appropriate tension, preventing connecting cable 3 from loosening and dangling in the air and reducing the possibility of workers coming into contact with connecting cable 3.

[0033] As a preferred technical measure of the present invention, notches 31 are drilled on both the left and right sides of arc-shaped block 27 along the horizontal direction, and threaded holes are drilled horizontally in the side walls of notches 31, and third bolts 32 are installed in the threaded holes. If connection cable 3 is too long, it can be wound around notch 31, and arc-shaped block 27 remains fixed during use. Therefore, even if connection cable 3 is accidentally pulled after being wound around notch 31 when no luggage is being transported, there will be no impact on female terminal 2. Connection cable 3 is first wound around notch 31 and then wound around winding rod 30. When connection cable 3 is pulled, winding rod 30 moves, and second spring 33 first provides a buffering effect to protect connection cable 3. Since connection cable 3 wound around notch 31 does not move, female terminal 2 is prevented from loosening, and the operation of the gateway device is more stable.

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

[0035] As shown in Figures 1 to 8, when in use, the gateway casing 1 is first attached to a predetermined position in the refrigerated warehouse, and if screws can be fastened to the wall of the refrigerated warehouse, the gateway casing 1 can be fixed using the bolt holes on the standing board 34. If screws cannot be fastened to the wall of the refrigerated warehouse, the gateway casing 1 can be hung and fixed to a shelf in the refrigerated warehouse using the fixing rings 20 and standing board 34. The gateway casing 1 is provided with multiple sets of fixing rings 20 and standing boards 34, and the lowest standing board 34 is flush with the bottom of the gateway casing 1, increasing stability when the standing board 34 is placed on the ground.

[0036] After the gateway casing 1 is installed, the retaining ring 17 is lifted upward to separate the two corresponding clamping rods 19. The connection cable 3 and female terminals 2 are passed through the retaining ring 17, and then the clamping rods 19 are inserted into the vertical grooves 18 to restrict the connection cable 3. The female terminals 2 are then inserted into the gateway casing 1. The retaining ring 17 lifts the connection cable 3, preventing excessive external force from being applied to the connection between the connection cable 3 and the female terminals 2, avoiding damage to the connection between the connection cable 3 and the female terminals 2 and extending the service life of the connection cable 3 and the female terminals 2. It is also possible to prevent the connection cable 3 from pulling the female terminals 2 downward under the action of gravity, which would loosen the engagement between the female terminals 2 and the male terminals and cause poor contact, which would affect the normal use of the gateway.

[0037] After the worker inserts the female terminal 2 into the gateway casing 1, the remaining portion of the connection cable 3 is wound around the winding rod 30, and the gateway device can be used normally.

[0038] The inner tube 5 is located inside the outer tube 4. When the worker inserts the female terminal 2 into the gateway casing 1, he pulls the first pushing block 11 outward to pull the inner tube 5 outward, then pushes the swash plate 7, causing the protrusion 8 to engage the locking groove 35 inside the inner tube 5, restricting the female terminal 2. The first pushing block 11 is then released, and the inner tube 5 is returned to its original position by the action of the first spring 9, firmly inserting the female terminal 2. The first spring 9 pulls the female terminal 2 toward the gateway casing 1, inserting the female terminal 2 into the gateway casing 1 and reducing the possibility of the female terminal 2 becoming loose. At the same time, even if the connection cable 3 is accidentally pulled when transporting luggage, the female terminal 2 can be prevented from becoming loose and coming off. Even if the female terminal 2 is pulled, it can be automatically returned to its original position by the action of the first spring 9, eliminating the need for the worker to reinsert the female terminal 2.

[0039] Since there are many luggage and shelves in a refrigerated warehouse, the connection cable 3 is easily pulled when transporting luggage. Therefore, by winding the excess part of the connection cable 3 around the winding rod 30, the connection cable 3 can be kept in a moderately taut state, preventing the connection cable 3 from loosening and dangling in the air, and reducing the possibility of workers touching the connection cable 3. If an operator accidentally touches and pulls the connection cable 3, the winding rod 30 moves horizontally and the second spring 33 provides a cushioning effect, further reducing the possibility of the female terminal 2 coming loose and improving the stability of the gateway device when in use.

[0040] If poor contact occurs in the female terminal 2 after long-term use, the corresponding electric push rod 12 is extended via an external controller, causing the stop plate 13 and second pushing block 14 to move away from the gateway casing 1, and the inner cylinder 5 moves the swash plate 7 and female terminal 2 together with the second pushing block 14 via the protrusion 8 and locking groove 35, thereby removing the female terminal 2. The electric push rod 12 is then returned to its original position, returning the stop plate 13, second pushing block 14, inner cylinder 5, protrusion 8, swash plate 7, and female terminal 2 to their original positions, completing the insertion and removal of the female terminal 2. This eliminates the need for operator intervention, and in many cases, the poor contact problem can be resolved by simply inserting or removing the female terminal 2, thereby saving operator time by automating the insertion and removal of the female terminal 2.

[0041] A limiting block 6 is provided on the outer wall of the inner tube 5, and the limiting block 6 can limit the inner tube 5 so that it can move only along the axial direction of the inner tube 5 and the outer tube 4. This allows the female terminal 2 to be aligned with the male terminal when inserted or removed, thereby preventing damage to the female terminal 2 or the male terminal due to misalignment when the female terminal 2 is inserted.

[0042] When the electric push rod 12 pushes the stop plate 13, the horizontal rod 15 and vertical rod 16 also move, and the vertical rod 16 moves the retainer ring 17 via the vertical groove 18 and clamping rod 19, and the retainer ring 17 supports the connection cable 3 as it moves. This prevents the angle of the female terminal 2 from being tilted and preventing accurate insertion into the male terminal, which not only results in failure of insertion of the female terminal 2 but also the possibility of 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 is only necessary 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 blocks 27 are slidably mounted on the fixed rings 20, and the corresponding arc-shaped blocks 27 can be moved after loosening the second bolts 29. When the gateway casing 1 needs to be installed at a corner, the arc-shaped blocks 27 can be moved at a certain angle along the fixed rings 20, facilitating installation of the gateway casing 1. After moving the arc-shaped blocks 27, the second bolts 29 can be tightened to fix the arc-shaped blocks 27 at any desired position on the fixed rings 20, making the operation simple and convenient. When the gateway casing 1 is to be fixed to a shelf or there is an object that can be fixed nearby, the arc-shaped blocks 27 can be rotated at a certain angle to position the shelf's fixing rod or other auxiliary fixing object into the notches 31, and then the third bolts 32 can be tightened to fix the gateway casing 1. This increases the number of ways to fix the gateway casing 1, and, in addition to being fixed by the uprights 34, the gateway casing 1 can be fixed more firmly.

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

[0046] If the connection cable 3 is too long, it can be wound around the notch 31, and the arc-shaped block 27 remains fixed during use. Therefore, even if the connection cable 3 is accidentally pulled after being wound around the notch 31 when no luggage is being carried, the female terminal 2 will not be affected. The connection cable 3 is first wound around the notch 31 and then wound around the winding rod 30. When the connection cable 3 is pulled, the winding rod 30 moves and the second spring 33 first exerts a buffering effect to protect the connection cable 3. The connection cable 3 wound around the notch 31 does not move, preventing the female terminal 2 from loosening and making the operation of the gateway device more stable.
