Description

Technical Field

[0001] The present invention relates to the field of early warning equipment, and in particular to a retractable interface for early warning equipment in a smart factory. Background Art

[0002] Smart factory is a new stage in the development of modern factory informatization. It is a new factory model that uses the Internet of Things technology and equipment monitoring technology to strengthen information management and services on the basis of digital factories, clearly grasp the production and sales process, improve the controllability of the production process, reduce manual intervention on the production line, collect production line data in real time and correctly, and reasonably arrange production plans and production progress. Compared with traditional factories, smart factories require fewer people in operation and more monitoring equipment and early warning equipment, and each device needs to be connected using the corresponding interface.

[0003] The interface of the existing smart factory early warning equipment can refer to the Chinese invention patent with publication number CN112736563A, which discloses in detail a power grid equipment communication data interface, whose structure includes a data box, a heat dissipation hole, an interface, and a connector. The heat dissipation hole and the data box are an integrated structure, and the interface is embedded and connected to the left and right sides of the inner front end of the data box. The interface is located at the front end of the heat dissipation hole, and the connector is movably engaged with the inner front end of the data box. The limit groove is embedded and connected to the left side of the upper end of the slot, and the swing plate is arranged at the upper end of the fixed plate. During use, the swing plate is pushed inward from the interface, and the sleeve groove is installed and wrapped around the outside of the control rod. During the ejection process, the control bonding plate will drive the top of the swing plate to slide on the inside under the limitation of the control rod, causing the swing plate to swing inward, and finally fit in the top recessed position, so that it can be smoothly inserted into the slot, and when pulled out, it will drive the swing plate to swing downward together, close its opening, and prevent dust from flying in from the opening position.

[0004] Although the above-mentioned equipment interface structure can effectively prevent dust, the dust generated during the processing of the smart factory is small and will not affect the electrical performance of the interface. In addition, the types of early warning equipment used in smart factories are diverse, and it is impossible to match the interfaces of many different types of early warning equipment. As a result, the early warning equipment needs to use various types of power supply interfaces when installed, which greatly increases the time and labor costs of laying out the early warning equipment.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Example

[0035] The contraction and fixing mechanism includes a contraction component, a driving component, a control component and a fixing component. The fixing component is arranged on the inner side of the contraction component, and the contraction component is used to push the fixing component to connect with the port of the early warning device, the driving component is used to drive the contraction component to perform contraction movement, and the control component is used to control the position of the driving component; the contraction component includes a rotating ring 21, the rotating ring 21 is rotatably connected to the outer shell 1, a sliding sleeve 22 is rotatably connected to the rotating ring 21, a pushing rod 23 is slidably connected inside the sliding sleeve 22, one end of the pushing rod 23 is rotatably connected to the inside of the outer shell 1, and the other end of the pushing rod 23 is rotatably connected to a pushing wheel 24, the pushing wheel 24 is made of nylon, the top end of the rotating ring 21 is fixedly connected to the connecting seat 25, the connecting seat 25 is rotatably connected to the screw sleeve 26, the screw sleeve 26 is threadedly connected to the screw 27, the screw 27 is rotatably connected to the fixing seat 28, and the fixing seat 28 is rotatably connected to the outer shell 1;

[0036] The driving assembly includes a gear 29, which is fixedly connected to the right side of the screw rod 27. The gear 29 meshes with the rack 30. The rear end of the rack 30 is fixedly connected with a sliding sleeve 31. The sliding sleeve 31 is slidably connected to the outside of the guide rod 32. The guide rod 32 is fixedly connected to the inside of the slide groove 33. The slide groove 33 is opened at a position close to the top of the connecting plate 34. The outside of the guide rod 32 is also wrapped with a first spring 35. The connecting plate 34 is fixedly connected to the extrusion button 36. The extrusion button 36 is slidably connected to the inside of the active cavity 37. The active cavity 37 is opened inside the housing 1. The inside of the active cavity 37 is also provided with The second spring 38, the top end of the first spring 35 is fixedly connected to the sliding sleeve 31, and the bottom end of the first spring 35 is fixedly connected to the inner wall of the sliding groove 33, one end of the second spring 38 is fixedly connected to the squeezing button 36, and the other end of the second spring 38 is fixedly connected to the inner wall of the active cavity 37; when the early warning device is to be connected to the shell 1, the power supply terminal of the early warning device is first inserted into the interior of the shell 1. When the power supply terminal is inserted into the interior of the shell 1, the power supply terminal pushes the squeezing button 36 to move toward the interior of the active cavity 37, so that the squeezing button 36 squeezes the second spring 38, so that the second spring 38 is squeezed. The second spring 38 generates elastic deformation, and the extrusion button 36 drives the rack 30 to move synchronously through the connecting plate 34 when moving, so that the rack 30 drives the meshing gear 29 to rotate, and the rotation of the gear 29 drives the fixedly connected screw 27 to rotate synchronously, and the rotation of the screw 27 drives the screw sleeve 26 threadedly connected to its outer side to move in the direction away from the fixed seat 28, and the screw sleeve 26 drives the rotating ring 21 to rotate through the connecting seat 25, and the rotating ring 21 drives the sliding sleeve 22 to rotate synchronously, so that the pushing rod 23 slidably connected to the sliding sleeve 22 drives the pushing wheel 24 to move to the center position of the rotating ring 21, and .... The driving wheel 24 pushes the fixed component to fit tightly against the outer side of the power supply terminal of the early warning device to supply power to the early warning device; when the screw 27 drives the screw sleeve 26 to move, due to the fixed connection between the connecting seat 25 and the rotating ring 21, the screw sleeve 26 will rotate around the center of the rotating ring 21 when moving, thereby lifting the gear 29 upward. At this time, the first spring 35, which is in a squeezed state, is released to a certain extent, thereby pushing the sliding sleeve 31 and the rack 30 to move upward, so that the rack 30 maintains a state of fitting with the gear 29, avoiding separation of the gear 29 and the rack 30.

[0037] The control component includes a storage chamber 39, which is opened at the bottom end of the squeezing button 36. The storage chamber 39 is slidably connected to a limit card 40 inside the storage chamber 39, and a third spring 41 is also provided inside the storage chamber 39. The limit card 40 is engaged with a card slot 42, and the card slot 42 is opened on the inner wall of a rotating plate 43. The rotating plate 43 is slidably connected to the inside of a rotating groove 44, and the rotating groove 44 is opened at the bottom end of the movable chamber 37. A fourth spring 45 is also provided inside the rotating groove 44. The bottom end of the rotating plate 43 is fixedly connected to a push plate 46, and the bottom end of the push plate 46 passes through the housing 1 and extends to the outside of the housing 1. The bottom end of the third spring 41 is fixedly connected to the limit card 40, and the third spring 41 is The top end is fixedly connected to the inner wall of the storage chamber 39, the bottom end of the limit card 40 is provided with an inclined surface, and the left side of the limit card 40 is provided with an arc surface, one side of the fourth spring 45 is fixedly connected to the rotating plate 43, and the other side of the fourth spring 45 is fixedly connected to the inner wall of the rotating groove 44, and the effect of the restoring force of the fourth spring 45 is achieved after the push plate 46 stops pushing, so as to facilitate the next connection of the power supply terminal of the early warning device; the squeezing button 36 drives the limit card 40 to move synchronously when moving into the inside of the active chamber 37, and at this time, the inclined surface provided at the bottom end of the limit card 40 is squeezed, so that the limit card 40 is squeezed to the storage chamber under the action of the squeezing force. The third spring 41 is elastically deformed when the first-aid device 30 stops inserting the first-aid device 30 and the first-aid device 30 stops moving. The first-aid device 30 is moved into the cavity 39 and squeezes the third spring 41, causing the third spring 41 to produce elastic deformation. When the power supply terminal of the early warning device stops being inserted, the squeezing button 36 no longer continues to move into the active cavity 37. At this time, the limit card 40 also stops moving synchronously and is inserted into the card slot 42 under the action of the restoring force of the third spring 41 and engages with the card slot 42, limiting the movement of the squeezing button 36. At this time, the squeezing button 36 cannot move forward, thereby allowing the wiring terminal of the early warning device to maintain a connected and conductive state. The squeezing button 36 is made of engineering plastic material, which can effectively prevent the current transmitted to the wiring terminal from being conducted to the housing 1 through the squeezing button 36. In this case, when the power supply to the terminal is to be released, it is only necessary to push the push plate 46 so that the slot 42 squeezes the arc surface opened on the left side of the limit card 40, so that the limit card 40 enters the interior of the storage cavity 39 under the action of the squeezing force and releases the state of being engaged with the slot 42. At this time, the movement of the squeezing button 36 is no longer restricted. The squeezing button 36 returns to its original position under the action of the restoring force of the active cavity 37, and pushes the terminal out. At the same time, when the squeezing button 36 moves, it drives the rack 30 to turn the gear 29 in the opposite direction through the connecting plate 34, so that the pushing wheel 24 moves in the opposite direction and no longer squeezes the fixed component, so that the fixed component is released from the state of being tightly fitted with the outer side of the terminal.

[0038] Further, the fixed component includes a conductive seat 47, the outer side of the conductive seat 47 abuts against the driving wheel 24, the rear end of the conductive seat 47 is fixedly connected with a conducting block 48, and the conductive seat 47 is electrically connected to the conducting block 48, the conducting block 48 is slidably connected to the guide rail 49, and the conducting block 48 is electrically connected to the guide rail 49, the guide rail 49 is fixedly connected to the inner wall of the movable groove 50, and the guide rail 49 is connected to the power supply through a wire, and the power supply is connected to the mains through a wire, the movable groove 50 is opened on the housing 1, and a fifth spring 52 is arranged inside the movable groove 50; one end of the conducting block 48 is fixedly connected to an insulating pad 51, the insulating pad 51 is made of rubber, one end of the fifth spring 52 abuts against the insulating pad 51, and the other end of the fifth spring 52 is fixedly connected to the inner wall of the movable groove 50;

[0039] During operation, when the power supply terminal of the early warning device is connected, the pushing wheel 24 pushes the conductive seat 47 to move toward the power supply terminal of the early warning device, and the arc-shaped protrusion on the inner wall of the conductive seat 47 first fits with the outer side of the power supply terminal. As the pushing wheel 24 continues to push, the outer side of the power supply terminal squeezes the inner wall of the conductive seat 47, so that the inner wall of the conductive seat 47 is elastically deformed under the action of the squeezing force and fits tightly to the outer side of the power supply terminal, thereby increasing the contact area with the power supply terminal and transmitting the current more stably. When the conductive seat 47 moves, the conductive member fixedly connected to the conductive seat 47 Block 48 slides synchronously on the outside of the guide rail 49 and the inside of the movable groove 50, and squeezes the fifth spring 52, so that the fifth spring 52 is elastically deformed under the action of the squeezing force. Through the restoring force of the fifth spring 52, the conductive seat 47 can automatically return to its original position after the power supply terminal of the early warning device is pulled out, so as to facilitate the connection between the power supply terminals of different early warning devices next time. In order to avoid the short circuit caused by the contact between the fifth spring 52 and the guide rail 49, the inner wall of the movable groove 50 is sprayed with insulating paint, which can effectively avoid the leakage caused by the accidental contact between the fifth spring 52 and the gear 29.

Those skilled in the art should understand that the present invention is not limited to the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, and these changes and improvements all fall within the scope of the present invention to be protected.
