Description

Technical Field

[0001] This utility model relates to the field of network equipment, and in particular to a protective PLC gateway. Background Technology

[0002] A PLC gateway is a device used in industrial automation and control systems to bridge and convert between different communication protocols. A PLC is a control device used in industrial automation, while a gateway is an intermediary that connects different types of networks or devices, enabling data communication and exchange between different systems.

[0003] However, existing protective PLC gateways have some shortcomings: on the one hand, some gateways have unreasonable designs for external cable connections, either the connections are not firm and are prone to loosening under external force, leading to signal transmission interruption, and they lack effective protection measures. Since the interface is exposed to the outside for a long time, dust and moisture in the air can easily be absorbed inside, thus affecting the connection signal of the plug. On the other hand, the installation structure of many gateways is not flexible enough and cannot easily adapt to the bolt hole requirements of different installation positions. Additional adapters may be required, increasing installation costs and time. Therefore, a protective PLC gateway is proposed to solve the above problems. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a protective PLC gateway, which aims to improve the existing technology that lacks effective protection measures and is prone to dust and moisture in the air accumulating inside the interface due to prolonged exposure.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a protective PLC gateway, comprising a body, three sets of mounting holes at the rear end of the body, external cables being detachably mounted on the inner wall of the mounting holes at the rear end of the body via shielding components, a glass cover plate being provided on the top surface of the body, guide grooves being provided on both sides of the body, multiple sets of mounting components being detachably mounted on the inner wall of the guide grooves, and four sets of foot pads being fixedly connected to the bottom end of the outer wall of the body, the shielding components including guide posts;

[0006] Two sets of baffles are slidably connected through the surface of the guide post. Contact blocks are fixedly connected to the surface of both sets of baffles. The baffles are elastically connected to the inner wall of the mounting hole of the machine body by a limiting spring.

[0007] As a further description of the above technical solution:

[0008] The mounting assembly includes mounting feet, the inner wall of which is elastically connected to a push block via a return spring, and the inner wall of the push block is slidably connected to a guide rod.

[0009] As a further description of the above technical solution:

[0010] The outer wall of the external cable contacts the inner wall of the mounting hole in the body, and the guide post is fixedly connected to the inner wall of the mounting hole in the body.

[0011] As a further description of the above technical solution:

[0012] One end of the limiting spring is fixedly connected to the inner wall of the mounting hole of the machine body, and the other end of the limiting spring is fixedly connected to the outer wall of the baffle. The baffle is slidably connected to the inner side wall of the mounting hole of the machine body.

[0013] As a further description of the above technical solution:

[0014] The rear end of the machine body has two sets of guide grooves, and the contact block is slidably connected to the inner wall of the guide groove through it. The outer wall of the shorter end of the contact block is in contact with the outer wall of the external cable.

[0015] As a further description of the above technical solution:

[0016] The outer wall of the mounting foot contacts the inner wall of the guide grooves on both sides of the machine body, and the push block is slidably connected to the inner wall of the mounting foot.

[0020] Multiple sets of through holes are opened at the top of the guide grooves on both sides of the machine body, and the end of the push block is inserted into the inner wall of the through hole of the guide groove of the machine body.

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, when an external cable is inserted, the inclined surface design of the contact block allows the baffle to automatically move outward to open the mounting hole. After the cable is fully inserted, the baffle, under the action of the limiting spring, makes tight contact with the outer wall of the cable, thereby pressing the cable and preventing it from loosening. At the same time, this design also effectively blocks external factors such as dust and moisture from entering the gateway from the interface, improving the reliability and stability of the gateway and reducing signal transmission failures caused by interface problems.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figure 1 - Figure 3This utility model provides an embodiment of a protective PLC gateway, comprising a body 1. Three sets of mounting holes are provided at the rear end of the body 1. An external cable 5 is detachably mounted on the inner wall of the mounting holes at the rear end of the body 1 via a shielding component 4. The external cable 5 is a connector of the gateway, which can transmit electrical signals and transmit network signals to other devices through the body 1. The outer wall of the external cable 5 contacts the inner wall of the mounting holes of the body 1. A glass cover 2 is provided on the top surface of the body 1. The glass cover 2 is a protective glass, and a touch screen is installed inside. The glass cover 2 protects the touch screen and facilitates touch operation. Guide grooves are provided on both sides of the body 1. Multiple sets of mounting components 3 are detachably mounted on the inner wall of the guide grooves of the body 1. By providing detachable mounting components 3, the mounting position of the body 1 can be adjusted according to the bolt holes corresponding to different mounting positions when the overall mounting position needs to be fixed.

[0033] Reference Figure 2 - Figure 4 Four sets of foot pads 6 are fixedly connected to the bottom of the outer wall of the body 1. The shielding component 4 includes a guide post 41, which is fixedly connected to the inner wall of the mounting hole of the body 1. Two sets of baffles 42 are slidably connected through the surface of the guide post 41. By setting the guide post 41, the movement position of the two sets of baffles 42 can be guided so that they can only move along the surface of the guide post 41. Contact blocks 43 are fixedly connected to the surface of the two sets of baffles 42. The contact blocks 43 are trapezoidal in shape and have inclined surfaces. When the external cable 5 is installed, it can push the two sets of contact blocks 43 synchronously through the inclined surfaces to drive the baffles 42 to move outward synchronously, thereby opening the corresponding mounting hole of the body 1.

[0034] Reference Figure 3 and Figure 4The baffle 42 is elastically connected to the inner wall of the mounting hole of the machine body 1 by a limiting spring 44. One end of the limiting spring 44 is fixedly connected to the inner wall of the mounting hole of the machine body 1, and the other end of the limiting spring 44 is fixedly connected to the outer wall of the baffle 42. The function of the limiting spring 44 is to automatically reset the position of the baffle 42 after it has been squeezed and moved by the contact block 43 when the contact with the outer wall of the external cable 5 is removed. Two sets of guide grooves are provided at the rear end of the machine body 1. The contact block 43 passes through and is slidably connected to the inner wall of the guide groove. The outer wall of the shorter end of the contact block 43 is connected to the outer wall of the external cable 5. The outer walls are in contact. The contact block 43 contacts the outer wall of the external cable 5, so that when the external cable 5 is installed, it will squeeze the inclined surfaces of the two sets of contact blocks 43, so that the contact blocks 43 drive the baffle 42 to move synchronously to open the corresponding mounting hole of the body 1. When the external cable 5 is fully inserted into the body 1, the two sets of baffles 42 and contact blocks 43 will be subject to the elastic action of the limiting spring 44 to contact the outer wall of the external cable 5, thereby pressing the position of the external cable 5 after installation. The baffle 42 is slidably connected to the inner side wall of the mounting hole of the body 1.

[0035] Reference Figure 2 and Figure 5 The mounting component 3 includes mounting feet 31. The outer wall of the mounting feet 31 contacts the inner wall of the guide grooves on both sides of the body 1. This contact allows for adjustment of the position of the mounting feet 31 when dealing with different mounting hole positions. A push block 32 is slidably connected to the inner wall of the mounting feet 31. The inner wall of the mounting feet 31 is elastically connected to the push block 32 via a return spring 33. Multiple sets of through holes are opened at the top of the guide grooves on both sides of the body 1. The end of the push block 32 is inserted into the inner wall of the through hole of the guide groove of the body 1. This insertion allows the mounting feet 31 to be mounted on the machine. Multiple positions for adjustment and movement are fixed within the guide groove of body 1. One end of the reset spring 33 is fixedly connected to the bottom end of the outer wall of the press block 32, and the other end of the reset spring 33 is fixedly connected to the bottom end of the inner wall of the mounting foot 31. The function of the reset spring 33 is to automatically reset the position of the press block 32 after it is pressed down and moved. The guide rod 34 is fixedly connected to the inner wall of the mounting foot 31. The inner wall of the press block 32 is slidably connected to the guide rod 34. By setting the guide rod 34, the position of the press block 32 after it is pressed down can be guided to avoid it from tilting up.

[0036] Working principle: When using this protective PLC gateway, first adjust the fixing method of the body 1 according to the installation position through the mounting component 3. When it is necessary to fix the body 1 according to the bolt holes corresponding to different installation positions, first adjust the position of the mounting feet 31 along the guide grooves on both sides of the body 1. During the adjustment process, press the button 32, so that the button 32 slides down along the direction of the guide rod 34 on the inner wall of the mounting feet 31. At this time, the return spring 33 is compressed, and the end of the button 32 disengages from the through hole at the top of the guide groove of the body 1. After moving the mounting feet 31 to the appropriate position, release the button 32. The button 32 automatically resets under the elastic action of the return spring 33, and its end inserts into the corresponding through hole at the top of the guide groove of the body 1, fixing the position of the mounting feet 31 in the guide groove of the body 1. In this way, the position of the mounting component 3 can be flexibly adjusted to adapt to the needs of different installation scenarios.

[0037] When installing the external cable 5, insert the external cable 5 into the mounting hole of the body 1. The outer wall of the external cable 5 first contacts the inclined surface of the contact block 43. Due to the trapezoidal shape and inclined surface design of the contact block 43, the external cable 5 will exert an outward squeezing force on the two sets of contact blocks 43. Under the action of the squeezing force, the contact block 43 drives the baffle 42 to move outward synchronously along the surface of the guide post 41. At this time, the limit spring 44 is stretched, and the corresponding mounting hole of the body 1 is opened. As the external cable 5 continues to be inserted, when the external cable 5 is fully inserted into the interior of the body 1, the two sets of baffles 42 and the contact block 43 are reset under the elastic action of the limit spring 44. The contact block 43 is in close contact with the outer wall of the external cable 5. This not only can press the position of the external cable 5 after installation to prevent it from loosening, but also play a certain role in sealing and protection, preventing external dust and other impurities from entering the interior of the body 1 through the mounting hole.

[0038] The glass cover 2 is an outer protective glass with a touch screen inside. On the one hand, it protects the touch screen from damage caused by direct contact with external objects; on the other hand, the glass material allows users to directly touch and operate the internal touch screen to control and set functions of the gateway. The four sets of feet 6 at the bottom of the outer wall of the body 1 are used to support the body 1, making the body 1 stable when placed, and at the same time, they can reduce friction and vibration between the body 1 and the placement surface to a certain extent, protecting the internal components of the body 1.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
