Description

Technical Field

[0001] This utility model relates to the field of serial port converter technology, and in particular to a serial port converter connector for ground meteorological observation equipment. Background Technology

[0002] Ground-based meteorological observation equipment primarily uses serial ports for readings, with RS232 being the most common, followed by RS485 and RS422. Currently, those working at the grassroots level are mostly veteran observers who are not very computer literate, making it quite troublesome to use different serial ports for different instruments each time.

[0003] Therefore, a serial port converter connector for ground meteorological observation equipment, with publication number CN222234071U, involves rotating a knob to drive a connecting shaft, which in turn drives a rotating frame. Simultaneously, the required model can be identified through a viewing window labeled with the model number. Then, rotating a screw guide frame moves along a guide rod, which in turn drives a drive rack, which in turn drives a rotating gear, which in turn drives a driven rack, pushing out the movable interface. Simultaneously, the guide frame engages a locking block with the locking gear to lock the rotating frame. This allows for switching between different specifications of movable interfaces without requiring personnel to carry multiple serial port converters.

[0004] However, the fixed interface is in a fixed position, while multiple movable interfaces can rotate inside the housing. Therefore, the fixed interface and multiple movable interfaces need to be connected by a wiring harness. The wiring harness will be pulled when the movable interface rotates. Therefore, if the operator keeps rotating in the same direction, the wiring harness is prone to tangling, which can easily lead to the wiring harness breaking. Utility Model Content

[0005] The purpose of this utility model is to solve the problems existing in the prior art by proposing a serial port conversion connector for ground meteorological observation equipment.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a serial port conversion connector for ground meteorological observation equipment, comprising a housing, a computer connector, and several serial port sockets of different models. A connecting cylinder is fixedly installed through the center of the top of the housing. An aviation plug connected to the computer connector via a wire harness is inserted into the inner wall of the connecting cylinder. A turntable is rotatably connected to the center of the bottom of the inner housing. Several serial port sockets are evenly distributed on the upper edge of the turntable, and a toothed ring with clearance fit is fixedly installed at the center of the upper surface of the turntable. An aviation socket connected in parallel with several serial port sockets and used for insertion with the aviation plug is installed on the upper surface of the toothed ring. An interface for alignment with one of the serial port sockets is provided on the outer side of the housing.

[0007] Preferably, a handle is rotatably connected through one side of the top of the outer shell, and a gear that meshes with a gear ring is fixedly installed on the end face of the handle located inside the outer shell.

[0008] Preferably, the top of the inner cylinder of the connecting cylinder is provided with an elastic rope that is connected to the computer connector harness.

[0009] Preferably, a pressing block is inserted into the upper part of the connecting cylinder wall, the portion of the pressing block inside the connecting cylinder extends downward and is fixed to the surface of the aviation plug, and the portion of the pressing block outside the connecting cylinder penetrates through the top of the outer shell.

[0010] Preferably, a positioning ring is fixedly installed on the upper surface of the turntable near each serial port socket, and the positioning ring is used to insert into the part of the pressing block that penetrates the outer shell.

[0011] Preferably, the positioning rings are distributed in a ring array about the aviation socket.

[0012] Preferably, a spring rod is installed between the pressing block and the outer wall of the connecting cylinder. The spring rod is set perpendicular to the top of the outer shell, and the top of the outer shell is rotatably connected to a locking block for engaging with the side of the pressing block via a spring hinge.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. In this utility model, by setting up an aviation plug and an aviation socket, when the turntable rotates to select the model of the serial port socket to be used, the corresponding serial port socket will rotate synchronously. The aviation plug descends in the connecting cylinder to achieve plugging with the aviation socket, thus realizing the connection between the computer connector and the serial port socket at the interface. When the aviation plug and aviation socket are separated, the personnel can rotate the turntable at will without causing the computer connector's wiring harness to be pulled and damaged.

[0015] 2. In this utility model, an elastic rope connected to the computer connector wire harness is provided at the top of the inner cylinder of the connecting cylinder. When the aviation plug descends, it will drive the wire harness connected to the computer connector to move accordingly, and at the same time drive the elastic rope to stretch elastically. Therefore, when the aviation plug rises, the elastic rope will be used to pull the wire harness to rise and reset. Attached Figure Description

[0021] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] like Figures 1-4As shown, a serial port converter connector for ground meteorological observation equipment includes a housing 1, a computer connector 2, and several serial port sockets 9 of different models. The computer connector 2 is a commonly used USB plug, and the serial port sockets 9 are RS232, RS485, and RS422. A connecting cylinder 5 is fixedly installed through the center of the top of the housing 1. An aviation plug 14 connected to the computer connector 2 via a wire harness is inserted into the inner wall of the connecting cylinder 5. An elastic rope 15 connected to the wire harness of the computer connector 2 is provided on the top of the inner cylinder of the connecting cylinder 5. When the aviation plug 14 descends, it will correspondingly drive the wire harness connected to the computer connector 2 to move, and at the same time drive the elastic rope 15 to stretch elastically. Therefore, when the aviation plug 14 rises, the elastic rope 15 will elastically contract to pull the wire harness to rise and return to its original position. A turntable 8 is rotatably connected to the center of the bottom of the inner shell of the housing 1. Several serial port sockets 9 are evenly distributed on the upper edge of the turntable 8. A gear ring 12 with clearance fit is fixedly installed at the center of the upper surface of the turntable 8. The turntable 8 is rotated by driving the gear ring 12. A handle 6 is rotatably connected through one side of the top of the outer shell 1. A gear 11 that meshes with the gear ring 12 is fixedly installed on the end face of the handle 6 inside the outer shell 1. The gear 11 is rotated by rotating the handle 6, thereby rotating the meshing gear ring 12. An aviation socket 13 is installed on the upper end face of the gear ring 12, which is connected in parallel with several serial port sockets 9 and is used to connect to the aviation plug 14. When the aviation plug 14 descends in the connecting cylinder 5, it connects to the aviation socket 13, thereby realizing signal transmission. An interface 7 is opened on the outer side of the outer shell 1 for aligning with one of the serial port sockets 9. The rotation of the turntable 8 moves one of the serial port sockets 9 to the position of the interface 7, which facilitates the serial port connection with the ground meteorological observation equipment.

[0024] Additionally: A pressing block 3 is inserted into the upper part of the connecting cylinder 5. The portion of the pressing block 3 inside the connecting cylinder 5 extends downward and is fixed to the surface of the aviation plug 14. The portion of the pressing block 3 outside the connecting cylinder 5 penetrates the top of the outer shell 1. A positioning ring 10 is fixedly installed on the upper surface of the turntable 8 near each serial port socket 9. The positioning ring 10 is used to insert into the portion of the pressing block 3 penetrating the outer shell 1. Several positioning rings 10 are arranged in a circular array about the aviation socket 13. When the corresponding serial port socket 9 moves to the insertion interface 7, pressing the pressing block 3 will cause the aviation plug 14 inside the connecting cylinder 5 to descend and insert into the aviation socket 13. When the pressing block 3 descends, the penetrating part through the top of the outer shell 1 will insert into the positioning ring 10 adjacent to the serial port socket 9 aligned with the insertion interface 7, thus fixing the position of the turntable 8 and preventing the turntable 8 from rotating. A spring rod 4 is installed between the pressing block 3 and the outer wall of the connecting cylinder 5. The spring rod 4 is set perpendicular to the top of the outer shell 1. Furthermore, the top of the outer shell 1 is rotatably connected to a locking block 18 via a spring hinge, which engages with the side of the pressing block 3. When the pressing block 3 descends, it causes the spring rod 4 to extend elastically until the pressing block 3 engages with the surface of the locking block 18. When the pressing block 3 needs to rise, simply move the locking block 18 to separate it from the pressing block 3. The pressing block 3 will then be pulled up by the elastic contraction of the spring rod 4, thus separating the aviation plug 14 from the aviation socket 13. In addition, the locking block 18 used in this solution has a beveled top and a flat bottom. When the pressing block 3 descends, it slides along the bevel of the locking block 18 until it contacts and overlaps with the flat bottom of the locking block 18, thus preventing the pressing block 3 from rising. Furthermore, the aviation plug 14 used in this solution can be a six-pin aviation plug with six pins arranged in a ring array inside. In addition, there are three serial port sockets 9 arranged in a ring array. Therefore, no matter which serial port socket 9 is aligned with the interface 7 when the turntable 8 rotates, the aviation plug 14 and the aviation socket 13 can be aligned.

[0025] Working principle: Based on the serial port model of the ground meteorological observation equipment, rotating the handle 6 rotates the gear 11, which in turn rotates the meshing gear ring 12. By driving the gear ring 12 to rotate, the turntable 8 rotates, causing the corresponding serial port socket 9 on the turntable 8 to move to the interface 7. Pressing the pressing block 3 causes the aviation plug 14 inside the connecting cylinder 5 to descend and connect with the aviation socket 13. When the pressing block 3 descends, the through-hole penetrating the top of the outer shell 1 will insert into the positioning ring 10 adjacent to the serial port socket 9 aligned with the interface 7, thus fixing the position of the turntable 8. The computer connector 2 connects to the computer. By connecting the aviation plug 14 to the aviation socket 13, the serial port on the ground meteorological observation equipment connects to the corresponding serial port socket 9 through the interface 7, thus enabling the computer to connect to the ground meteorological observation equipment.

[0026] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the present utility model.
