Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of cable winding and unwinding devices, specifically a sensor cable winding and unwinding device. Background Technology
[0002] Sensors are common electronic products. Calibration equipment used to calibrate new products employs numerous sensors, whose connecting cables are typically quite long. A well-organized cable management system is essential to prevent a chaotic calibration environment. Therefore, a simple and practical cable management device is needed for calibration work environments, capable of simultaneously managing multiple sensor cables. Utility Model Content
[0003] The purpose of this invention is to provide a sensor cable retraction device that is simple and practical, and can simultaneously retract and extend multiple sets of sensor cables.
[0004] To achieve the above objectives, this utility model provides the following technical solution:
[0005] A sensor cable take-up and take-down device includes a cable reel, a take-up mechanism, and a cable distributor. The cable reel has cable retaining discs on both sides and a rotating shaft connecting the two cable retaining discs in the middle. The rotating shaft has a shaft hole in the middle. The take-up mechanism includes a take-up shaft and a support base. The take-up shaft includes a central circular shaft and connecting shafts at both ends of the circular shaft. The connecting shafts are rotatably connected to the support base. The circular shaft has several cable reels, and the circular shaft and the cable reel shaft holes are connected by a key. The cable distributor is located on one side of the take-up mechanism. The top of the cable distributor has several open U-shaped grooves, and the positions of the cable reels on the circular shaft correspond to the open U-shaped grooves.
[0006] In this solution, a structure with multiple reels on a single take-up spool is adopted, which can simultaneously take in and unload multiple sensor cables. When the take-up spool is rotated, the reels rotate together with the take-up spool. Each sensor cable corresponds to one reel, and the sensor cables pass through the corresponding open U-shaped grooves, so that multiple sensor cables will not tangle with each other. The reels and the take-up spool are keyed together and will not rotate with each other. The reels can be put onto the round shaft from both ends of the take-up spool or removed from the round shaft.
[0007] In a preferred embodiment of this utility model, the take-up device and the wire divider are mounted on a workbench. The support base is connected to the workbench via a pin. The top of the support base has a semi-circular support hole. The connecting shafts at both ends of the take-up shaft are respectively placed in the semi-circular support holes and rotatably connected to the support base. A handwheel is connected to the connecting shaft at one end of the take-up shaft. This embodiment is designed for the take-up and unwinding of sensor cables. Sensor cables are relatively thin in diameter and generally tens of meters in length, so they can be manually taken up and unwound using a handwheel. The diameter of the round shaft in the middle of the take-up shaft is larger than that of the connecting shafts at both ends. The connecting shafts are rotatably connected to the support holes at the top of the support base. The round shaft is located between the support bases at both ends. The support bases are fixed to the workbench and can be either detachable (bolted connection, etc.) or non-detachable (welded, etc.). When taking up or unwinding the reel, the take-up shaft is removed from the support holes, and the reel can be slipped onto the round shaft from both ends.
[0008] As a preferred embodiment of this utility model, the top of the support seat is provided with a semi-circular limiting buckle, which is connected to the top of the support seat. A gap is provided between the semi-circular limiting buckle and the connecting shafts at both ends of the take-up shaft. The limiting buckle in this embodiment is to increase the safety of the rotational connection between the connecting shaft and the support seat, preventing excessive force applied to the handwheel end of the connecting shaft from causing the other end of the connecting shaft to detach from the support hole. Under normal conditions, the limiting buckle does not contact the connecting shaft; the limiting buckle and the support seat are bolted together.
[0009] As a preferred embodiment of this utility model, a baffle is provided at the bottom of the workbench, and the baffle is fixedly connected to the workbench. The workbench of this embodiment has an internal space that can be used to place a spool, support base, take-up spool, etc.
[0010] As a preferred embodiment of this utility model, the circular shaft is provided with three keyways parallel to the axis, and the wall of the shaft hole of the coil rotating shaft is provided with a key bar or a keyway. This embodiment can employ keyways on the circular shaft and the coil shaft hole, with a key bar placed in the keyways, or keyways on the circular shaft, with a protruding ridge on the coil shaft hole serving as a key bar; the three keyways and the key bar are evenly distributed, and the key bar and keyways are fitted together to ensure a connection that is neither too loose nor too tight.
[0011] As a preferred embodiment of this utility model, a U-shaped pressure line is provided at the opening of the U-shaped groove of the splitter plate, and the two ends of the opening of the U-shaped pressure line are connected to the splitter plate. In this embodiment, the U-shaped pressure line is set at the opening of the U-shaped groove of the splitter plate through which the sensor cable passes, to prevent the sensor cable from coming off the U-shaped groove of the splitter plate during retraction; the U-shaped pressure line can be directly inserted into the socket on the splitter plate by plugging it in.
[0012] The advantages of this invention are: it is simple and practical, and can simultaneously store and retract multiple sets of sensor cables. Attached Figure Description
