Description

Technical Field

[0001] The present invention relates to the field of communication technology, and in particular to a wireless communication gateway based on digital remote communication in a cold storage. Background Art

[0002] The gateway device is used to connect network devices and networks. It is an internet connector or a protocol converter. A gateway is a computer system or device that performs the conversion task. It is used between two systems with different communication protocols, data formats or languages, or even completely different architectures. A gateway is a translator. Unlike a bridge that simply transmits information, a gateway repackages the received information to meet the needs of the destination system. Common gateway devices for home use are routers, etc., while gateway devices for industrial use can bridge different systems based on different communication protocols.

[0003] When the existing gateway device is used in a cold storage, because the goods are stored in the cold storage, there will be staff frequently going in and out to take and put the goods. In the process of taking and putting the goods, they may touch the connecting wires or the gateway housing, which may cause the female plug and the male plug to loosen. After the gateway device is used for a long time, the female plug and the male plug are also prone to poor contact. The staff is required to unplug the female plug and reinsert it into the male plug. However, in order not to affect the staff's taking and putting of goods, the gateway device in the cold storage is generally installed in a higher position. It is very inconvenient and difficult for the staff to unplug and plug the female plug. Summary of the invention

[0016] After adopting the above technical solution, the beneficial effects of the present invention are:

[0017] 1. When the female end plug has poor contact after long-term use through the electric push rod, baffle, second push block, inner cylinder, protrusion and inclined plate, the external controller controls the corresponding electric push rod to extend, thereby driving the baffle and the second push block to move away from the gateway housing, and the inner cylinder drives the inclined plate and the female end plug to move with the second push block through the protrusion and the slot, so as to unplug the female end plug, and then the electric push rod is reset, driving the baffle, the second push block, the inner cylinder, the protrusion, the inclined plate and the female end plug to reset, completing the plugging and unplugging action of the female end plug, avoiding the need for staff to operate. In most cases, the problem of poor contact can be solved by plugging and unplugging the female end plug, so automatic plugging and unplugging of the female end plug can save staff time.

[0018] 2. When the female plug is inserted into the gateway housing, the inner tube is pulled outward by pulling the first push block outward, and then the inclined plate is pressed to make the protrusion stuck in the slot inside the inner tube, thereby limiting the position of the female plug. The first push block is released, and the inner tube is reset under the action of the first spring, so that the female plug is tightly inserted. The first spring will make the female plug tightly inserted into the gateway housing, reducing the possibility of the female plug being loosened. At the same time, when the connecting line is accidentally pulled when transporting goods, the female plug can also be prevented from being pulled loose. Even if the female plug is pulled, it can be automatically reset under the action of the first spring, avoiding the need for staff to tighten the female plug.

[0019] 3. Through the arc block, the notch and the third bolt, the corresponding arc block can be moved after loosening the second bolt. When the gateway housing needs to be installed in the corner, the arc block can be moved along the fixing ring at a certain angle to facilitate the installation of the gateway housing. After moving the arc block, the arc block can be fixed at any moved position on the fixing ring by tightening the second bolt. The operation is simple and convenient. When the gateway housing is fixed on a shelf or there are objects around that can assist in fixing, the arc block can be rotated at a certain angle so that the fixing rod of the shelf or other auxiliary fixing objects are located in the notch, and then the third bolt is tightened to fix it. This can increase the fixing method of the gateway housing and make the gateway housing more firmly fixed on the basis of fixing it through the vertical plate.

[0020] 4. The arc ring is connected to the fixing ring through the fixing block, the circular hole, the first bolt and the fixing groove. When a fault occurs inside the gateway device, the staff can remove the arc ring by unscrewing the first bolt, thereby disassembling the gateway shell. When the arc block needs to be removed, the arc ring can be removed in the same way, and then the arc block can be removed. The operation is simple.

[0021] 5. Through the winding rod, the second spring, the arc block and the notch, when the connecting wire is too long, the connecting wire can be wound around the notch. Since the arc block is fixed during use, after the connecting wire is wound around the notch, it will not have any effect on the female plug if the connecting wire is accidentally pulled when not moving goods. The connecting wire is first wound around the notch and then around the winding rod. When the connecting wire is pulled, the winding rod moves, and the second spring first performs buffering to protect the connecting wire. The connecting wire wound around the notch will not move, protecting the female plug from loosening, thereby making the gateway device run more stably. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0032] The specific implementation of the present invention is further described in detail below in conjunction with 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.

[0033] The present invention provides a wireless communication gateway based on digital remote communication in a cold storage. The installation method, connection method or setting method of all the above-mentioned components are common mechanical methods, and the specific structures, models and coefficient indicators of all its components are its own technology. As long as it can achieve its beneficial effects, it can be implemented, so it will not be elaborated.

[0034] The present invention provides a wireless communication gateway based on digital remote communication in a cold storage. Unless otherwise specified, the directional words contained in the terms such as "up, down, left, right, front, back, inside, outside, and vertical and horizontal" only represent the orientation of the term in normal use, or are common names understood by those skilled in the art, and should not be regarded as limitations on the term. At the same time, number series nouns such as "first", "second" and "third" do not represent specific quantities and orders, but are only used to distinguish names. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or equipment including a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or equipment.

[0035] Example:

[0036] like Figure 1-8As shown, a wireless communication gateway based on digital remote communication in a cold storage comprises: a gateway housing 1, a male plug, a female plug 2 and a connecting line 3, wherein the male plug is arranged on the gateway housing 1, one end of the female plug 2 is connected to the connecting line 3, and the other end cooperates with the male plug, an outer tube 4 is arranged on the outer side of the male plug, an inner tube 5 is slidably mounted on the inner wall of the outer tube 4, the female plug 2 is connected to the inner wall of the inner tube 5, a second push block 14 is arranged at the bottom of the outer tube 4, the second push block 14 passes through the side wall of the outer tube 4, and a groove for the second push block 14 to move is arranged on the side wall of the outer tube 4, the top of the second push block 14 is fixedly connected to the outer wall of the inner tube 5, a baffle 13 is fixedly connected to one side of the bottom of the second push block 14, and the baffle 13 is close to the gateway housing An electric push rod 12 is provided on one side of the body 1, one end of the electric push rod 12 is fixedly connected to the gateway shell 1, and the other end is fixedly connected to the baffle 13. A first spring 9 is provided on one end of the inner cylinder 5 close to the gateway shell 1, one end of the first spring 9 is fixedly connected to the inner cylinder 5, and the other end is fixedly connected to the outer wall of the gateway shell 1. Card grooves 35 are provided on both sides of the inner cylinder 5, and inclined plates 7 are provided on both sides of the female end plug 2. One end of the inclined plate 7 is fixedly connected to the female end plug 2, and a protrusion 8 is provided in the middle of the inclined plate 7, which can be stuck in the card groove 35. A first push block 11 is also provided on one side of the inner cylinder 5, and a first push groove 10 is correspondingly provided on one side of the outer cylinder 4. A limit block 6 is provided on the outer wall of the inner cylinder 5, and a limit groove is correspondingly provided on the side wall of the outer cylinder 4. When the female plug 2 is inserted into the gateway housing 1, the inner cylinder 5 is pulled outward by pulling the first push block 11 outward, and then the inclined plate 7 is pressed to make the protrusion 8 stuck in the card groove 35 inside the inner cylinder 5, thereby limiting the female plug 2, and releasing the first push block 11. Under the action of the first spring 9, the inner cylinder 5 is reset, thereby tightening the female plug 2. Since the first spring 9 will pull the female plug 2 toward the gateway housing 1, the female plug 2 is tightly inserted into the gateway housing 1, reducing the possibility of the female plug 2 loosening. At the same time, when the connecting line 3 is accidentally pulled when transporting goods, the female plug 2 can also be prevented from being pulled loose. Even if the female plug 2 is pulled, it can be automatically reset under the action of the first spring 9, avoiding the need for staff to tighten the female plug 2. When the female plug 2 has poor contact after long-term use, the external controller controls the corresponding electric push rod 12 to extend, thereby driving the baffle 13, the inner tube 5 and the female plug 2 to move, and the female plug 2 is unplugged. Then the electric push rod 12 is reset, driving the female plug 2 to reset, and the plugging and unplugging action of the female plug 2 is completed, avoiding the need for staff to operate. In most cases, the problem of poor contact can be solved by plugging and unplugging the female plug 2, so automatic plugging and unplugging of the female plug 2 can save staff time.

[0037] A limit block 6 is provided on the outer wall of the inner cylinder 5, and the limit block 6 can limit the inner cylinder 5 so that the inner cylinder 5 can only move along the axial direction of the inner cylinder 4 and the outer cylinder 5, so that the female plug 2 can be aligned with the male plug during the plugging and unplugging process, thereby preventing the female plug 2 from being inserted off-center and causing damage to the female plug 2 or the male plug.

[0038] As a technical optimization solution of the present invention, a cross bar 15 is fixedly connected to the bottom of the second push block 14, and a vertical rod 16 is fixedly connected to one end of the cross bar 15 away from the second push block 14. A clamp ring 17 is provided on the top of the vertical rod 16. The clamp ring 17 is located at the same horizontal line as the center of the female end plug 2, and the connecting wire 3 passes through the clamp ring 17. The clamp ring 17 holds up the connecting wire 3, which can prevent the connection between the connecting wire 3 and the female end plug 2 from being subjected to excessive force, thereby preventing the connection between the connecting wire 3 and the female end plug 2 from being damaged, increasing the life of the connecting wire 3 and the female end plug 2, and preventing the connecting wire 3 from pulling the female end plug 2 downward under the action of gravity, causing the female end plug 2 to loosen the fit with the male end plug, causing poor contact, and affecting the normal use of the gateway. When the electric push rod 12 pushes the baffle 13 to move, the cross bar 15 and the vertical bar 16 also move with it. The vertical bar 16 drives the clamping ring 17 to move through the vertical groove 18 and the clamping rod 19. The clamping ring 17 will support the connecting wire 3 when it moves to prevent the connecting wire 3 from getting stuck during the movement of the female plug 2 or pulling the female plug 2 downward for other reasons, causing the female plug 2 to tilt at an angle and unable to be accurately inserted into the male plug, causing the female plug 2 to fail to insert.

[0039] As a technical optimization solution of the present invention, the clamping ring 17 is composed of two half rings, the bottom of the half ring is fixedly connected with a clamping rod 19, and the top of the vertical rod 16 is vertically provided with a vertical groove 18, and the two clamping rods 19 are inserted into the vertical groove 18. When installing and disassembling, it is only necessary to take the clamping ring 17 and the clamping rod 19 out of the vertical groove 18, which is simple and convenient to operate.

[0040] As a technical optimization scheme of the present invention, a fixing ring 20 is connected to the outer wall of the gateway shell 1, and the inner side of the fixing ring 20 is fixedly connected to the outer wall of the rear end of the gateway shell 1. An annular groove 22 is provided on the top of the fixing ring 20, and an arc block 27 is installed on the outer side of the fixing ring 20. A through groove 28 is penetrated through the arc block 27. The fixing ring 20 penetrates the through groove 28 and is slidably connected to the inner wall of the through groove 28. A second bolt 29 is threadedly connected to the upper part of the arc block 27, and the bottom of the second bolt 29 abuts against the top of the fixing ring 20. The arc block 27 is slidably installed on the fixing ring 20. After loosening the second bolt 29, the corresponding arc block 27 can be moved. When the gateway housing 1 needs to be installed in the corner, the arc block 27 can be moved along the fixing ring 20 by a certain angle, which is convenient for the installation of the gateway housing 1. After moving the arc block 27, the arc block 27 can be fixed at any moved position on the fixing ring 20 by tightening the second bolt 29. The operation is simple and convenient. When the gateway housing 1 is fixed on a shelf or there are objects around that can assist in fixing, the arc block 27 can be rotated by a certain angle so that the fixing rod of the shelf or other auxiliary fixing objects are located in the notch 31, and then the third bolt 32 is tightened for fixing. This can increase the fixing method of the gateway housing 1 and make the gateway housing 1 more firmly fixed on the basis of fixing it by the vertical plate 34.

[0041] As a technical optimization solution of the present invention, an arc ring 21 is provided on one side of the fixing ring 20, and the fixing ring 20 and the arc ring 21 form a ring. The arc ring 21 is located at the front end of the gateway housing 1, and fixing blocks 24 are provided at both ends of the arc ring 21. A circular hole 25 is vertically opened on the fixing block 24. A fixing groove 23 is opened at both ends of the fixing ring 20, and a first bolt 26 is provided above the fixing groove 23. The fixing block 24 can be inserted into the fixing groove 23 and the first bolt 26 can pass through the circular hole 25. The arc ring 21 is connected to the fixing ring 20 through the fixing block 24, the circular hole 25, the first bolt 26 and the fixing groove 23. When a fault occurs inside the gateway device, the staff can remove the first bolt 26 to remove the arc ring 21, thereby disassembling the gateway housing 1, and when the arc block 27 needs to be removed, the arc block 27 can be removed after the arc ring 21 is removed in the same way, which is simple to operate.

[0042] As a technical optimization solution of the present invention, a sliding groove is horizontally provided on one side of the arc block 27 away from the gateway housing 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 the other end is provided with a baffle, and a second spring 33 is provided in the sliding groove, one end of the second spring 33 is fixedly connected to the winding rod 30, and the other end is fixedly connected to the inner wall of the sliding groove. There are many goods and shelves in the cold storage. When carrying goods, it is easy to pull the connecting wire 3. Wrapping the excess connecting wire 3 around the winding rod 30 can make the connecting wire 3 in a relatively tight state, avoid the connecting wire 3 hanging loosely in the air, and reduce the possibility of the staff touching the connecting wire 3.

[0043] As a technical optimization solution of the present invention, the arc block 27 is provided with notches 31 on both sides along the horizontal direction, and threaded holes are provided horizontally on the side walls of the notch 31, and third bolts 32 are provided in the threaded holes. When the connecting wire 3 is too long, the connecting wire 3 can be wrapped around the notch 31. Since the arc block 27 is in a fixed state during use, after the connecting wire 3 is wrapped around the notch 31, if the connecting wire 3 is accidentally pulled when not moving goods, it will not have any effect on the female plug 2. The connecting wire 3 is first wrapped around the notch 31 and then wrapped around the winding rod 30. When the connecting wire 3 is pulled, the winding rod 30 moves, and the second spring 33 first performs buffering to protect the connecting wire 3. The connecting wire 3 wrapped around the notch 31 will not move, and the female plug 2 will not be loosened, thereby making the gateway device run more stably.

[0044] As a technical optimization solution of the present invention, a vertical plate 34 is fixedly connected to the bottom of the fixing ring 20 . The vertical plate 34 is located at the rear end of the gateway housing 1 , and a fixing hole is opened on the vertical plate 34 .

[0045] like Figure 1-Figure 8 As shown, when in use, the gateway housing 1 is first installed at a preset position on the cold storage. When screws can be driven into the wall of the cold storage, the gateway housing 1 can be fixed using the bolt holes on the vertical plate 34. When screws cannot be driven into the wall of the cold storage, the gateway housing 1 can be hung on the shelf of the cold storage using the fixing ring 20 and the vertical plate 34, thereby fixing the gateway housing 1. Multiple sets of fixing rings 20 and vertical plates 34 are provided on the gateway housing 1. The bottom vertical plate 34 is flush with the bottom of the gateway housing 1, thereby increasing stability when the vertical plate 34 is placed on the ground.

[0046] After installing the gateway housing 1, lift the clamping ring 17 upwards to separate the corresponding two clamping rods 19, pass the connecting wire 3 and the female plug 2 through the clamping ring 17, and then insert the clamping rod 19 into the vertical groove 18 to limit the connecting wire 3, and then insert the female plug 2 into the gateway housing 1. Since the clamping ring 17 holds up the connecting wire 3, excessive force can be prevented at the connection between the connecting wire 3 and the female plug 2, thereby avoiding damage to the connection between the connecting wire 3 and the female plug 2, increasing the life of the connecting wire 3 and the female plug 2, and avoiding the connecting wire 3 from pulling the female plug 2 downward under the action of gravity, resulting in loosening of the fit between the female plug 2 and the male plug, causing poor contact and affecting the normal use of the gateway.

[0047] After the staff inserts the female end plug 2 into the gateway housing 1, the staff winds the redundant connecting wire 3 around the winding rod 30, and the gateway device can be used normally.

[0048] The inner cylinder 5 is located in the outer cylinder 4. When the staff inserts the female plug 2 into the gateway shell 1, they pull the first push block 11 outward to pull the inner cylinder 5 outward, and then press the inclined plate 7 to make the protrusion 8 get stuck in the slot 35 inside the inner cylinder 5, thereby limiting the female plug 2, and then release the first push block 11. Under the action of the first spring 9, the inner cylinder 5 is reset, thereby tightening the female plug 2. Since the first spring 9 will pull the female plug 2 toward the direction close to the gateway shell 1, the female plug 2 is tightly inserted into the gateway shell 1, reducing the possibility of the female plug 2 loosening. At the same time, when the connecting line 3 is accidentally pulled when transporting goods, the female plug 2 can also be prevented from being pulled loose. Even if the female plug 2 is pulled, it can be automatically reset under the action of the first spring 9, avoiding the need for the staff to tighten the female plug 2.

[0049] There are many goods and shelves in the cold storage. When carrying goods, the connecting wire 3 is easily pulled. The excess connecting wire 3 is wound around the winding rod 30, so that the connecting wire 3 is in a relatively tight state, and the connecting wire 3 is prevented from hanging loosely in the air, thereby reducing the possibility of workers touching the connecting wire 3.

[0050] When the staff accidentally touches and pulls the connecting line 3, the winding rod 30 can move in the horizontal direction, and the second spring 33 can provide buffering, further reducing the possibility of the female plug 2 loosening, making the gateway device more stable when in use.

[0051] When the female plug 2 has poor contact after long-term use, the corresponding electric push rod 12 is controlled to extend by an external controller, thereby driving the baffle 13 and the second push block 14 to move away from the gateway housing 1, and the inner cylinder 5 drives the inclined plate 7 and the female plug 2 to follow the second push block 14 through the protrusion 8 and the slot 35, so that the female plug 2 is unplugged, and then the electric push rod 12 is reset, driving the baffle 13, the second push block 14, the inner cylinder 5, the protrusion 8, the inclined plate 7 and the female plug 2 to reset, completing the plugging and unplugging action of the female plug 2, avoiding the need for staff to operate. In most cases, the problem of poor contact can be solved by plugging and unplugging the female plug 2, so automatic plugging and unplugging of the female plug 2 can save staff time.

[0052] A limit block 6 is provided on the outer wall of the inner cylinder 5, and the limit block 6 can limit the inner cylinder 5 so that the inner cylinder 5 can only move along the axial direction of the inner cylinder 4 and the outer cylinder 5, so that the female plug 2 can be aligned with the male plug during the plugging and unplugging process, thereby preventing the female plug 2 from being inserted off-center and causing damage to the female plug 2 or the male plug.

[0053] When the electric push rod 12 pushes the baffle 13 to move, the cross bar 15 and the vertical bar 16 also move with it. The vertical bar 16 drives the clamping ring 17 to move through the vertical groove 18 and the clamping rod 19. The clamping ring 17 will support the connecting wire 3 when it moves to prevent the connecting wire 3 from getting stuck during the movement of the female plug 2 or pulling the female plug 2 downward for other reasons, causing the female plug 2 to tilt at an angle and unable to be accurately inserted into the male plug, causing the female plug 2 to fail to be inserted, and may even cause damage to the female plug 2 or the male plug.

[0054] The clamping ring 17 is inserted into the vertical groove 18 through the clamping rod 19. When installing and disassembling, the clamping ring 17 and the clamping rod 19 only need to be taken out from the vertical groove 18, which is simple and convenient to operate.

[0055] The arc block 27 is slidably installed on the fixing ring 20. After loosening the second bolt 29, the corresponding arc block 27 can be moved. When the gateway housing 1 needs to be installed in the corner, the arc block 27 can be moved along the fixing ring 20 by a certain angle, which is convenient for the installation of the gateway housing 1. After moving the arc block 27, the arc block 27 can be fixed at any moved position on the fixing ring 20 by tightening the second bolt 29. The operation is simple and convenient. When the gateway housing 1 is fixed on a shelf or there are objects around that can assist in fixing, the arc block 27 can be rotated by a certain angle so that the fixing rod of the shelf or other auxiliary fixing objects are located in the notch 31, and then the third bolt 32 is tightened for fixing. This can increase the fixing method of the gateway housing 1 and make the gateway housing 1 more firmly fixed on the basis of fixing it by the vertical plate 34.

[0056] The arc ring 21 is connected to the fixing ring 20 through the fixing block 24, the circular hole 25, the first bolt 26 and the fixing groove 23. When a fault occurs inside the gateway device, the staff can remove the arc ring 21 by unscrewing the first bolt 26, thereby disassembling the gateway shell 1. When the arc block 27 needs to be removed, the arc ring 21 can be removed in the same way, and then the arc block 27 can be removed. The operation is simple.

[0057] When the connecting wire 3 is too long, the connecting wire 3 can be wrapped around the notch 31. Since the arc block 27 is in a fixed state during use, after the connecting wire 3 is wrapped around the notch 31, even if the connecting wire 3 is accidentally pulled when not moving goods, it will not have any effect on the female plug 2. The connecting wire 3 is first wrapped around the notch 31 and then wrapped around the winding rod 30. When the connecting wire 3 is pulled, the winding rod 30 moves, and the second spring 33 first performs buffering to protect the connecting wire 3. The connecting wire 3 wrapped around the notch 31 will not move, and the female plug 2 will not loosen, thereby making the gateway device run more stably.

[0058] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
