Description

Technical Field

[0001] This utility model relates to an inductive switch, and more particularly to a split-type inductive foot switch device. Background Technology

[0002] With the rapid development and continuous maturation of mechanization, various automated electrical equipment is widely used. Some of these devices, for ease of operation, employ inductive foot switches to control the start and stop of the equipment. For example, an inductive foot switch device (patent number: CN201922141247.6) includes: an arched protective cover, integrally molded from metal or plastic; the arched protective cover has a cavity opening to one side, with a bottom plate inside the cavity and a touch plate on the bottom plate, the touch plate equipped with a sensor; when a foot is placed into the cavity, the sensor receives a signal and feeds it back to the controller to initiate the opening action. In use, when a foot is placed into the cavity, the sensor receives a signal and feeds it back to the controller to initiate the opening action. Due to the use of electronic inductive control, mechanical failures are avoided; it has a simple structure, is easier to manufacture, eliminates the possibility of malfunction due to pressure, and has good control stability. It is a furniture production equipment device with superior technical, economic, and practical advantages.

[0003] Existing inductive foot switches combine the sensor and foot pedal structure in a control box to form a control unit. The sensor is then connected to the device components via wiring to form a control circuit. Since the foot pedal structure is usually installed or placed on the ground for the convenience of operators, this method of placing it on the ground is easily affected by the external environment, and is prone to collision damage, water ingress corrosion, or short circuits, which can damage the sensor and shorten its service life. Utility Model Content

[0004] The technical problem to be solved by this utility model is: to address the technical defects of existing inductive foot switches that are easily damaged by impacts or short-circuited by water corrosion, which in turn damages the sensor and shortens its service life, and to provide a split-type inductive foot switch device.

[0005] To solve the above-mentioned technical problems, this utility model adopts the following technical solution: A split-type inductive foot switch device includes a base plate, a foot pedal, a mounting box, and a steel wire rope. The foot pedal is suspended on the base plate. A support plate B is provided on both sides of the middle of the top surface of the base plate. A rotating shaft is provided between the two support plates B. The two ends of the rotating shaft are respectively connected to the two support plates B through a bearing A. The rotating shaft passes through the foot pedal. The top surface of the base plate is provided with a pair of support plates A, and a roller is provided between the two support plates A. The foot pedal is provided with a connector near the roller end. One end of the bottom surface of the mounting box is provided with a sliding plate, one side of the top surface of the sliding plate is provided with a sensing metal block, and a binding shaft is provided in the middle of the top surface of the sliding plate. A sensor is provided on the bottom surface of the mounting box aligned with the sensing metal block. The sensor can be connected to the control box of the equipment via a circuit. After one end of the wire rope is connected to the connector, it passes around the bottom of the roller and through the side wall of the mounting box, and the other end is connected to the binding shaft. A telescopic spring is installed on the section of the wire rope between the mounting box and the binding shaft. One end of the telescopic spring is connected to the binding shaft and the other end is connected to the side wall of the mounting box.

[0006] Preferably, each end of the roller is provided with a connecting shaft, and the two connecting shafts are respectively connected to the two support plates B through a bearing B.

[0007] Preferably, the roller has a groove in the middle, the depth and width of which are the same as the diameter of the wire rope. The groove in the middle of the roller, with its depth and width matching the diameter of the wire rope, serves to limit movement and prevent slippage.

[0008] Preferably, a vertical plate is provided on the top surface of the base plate near the roller, and a through hole is formed on the vertical plate through which the wire rope passes. The vertical plate with the through hole serves to limit the movement of the wire rope after it emerges from the bottom of the roller, preventing bending or pulling of the wire rope from interfering with the wire rope section passing through the roller, and thus improving the stability of the wire rope's tension.

[0009] Preferably, a groove is formed at the bottom of each of the two side walls of the mounting box, and the two ends of the slide plate slide into the two grooves. The grooves inside the mounting box allow the slide plate to slide along a fixed trajectory.

[0010] Preferably, the length of the slide plate is the same as the distance between the two inner walls of the two slide grooves. Matching the length of the slide plate to the distance between the two slide grooves can prevent the slide plate from sliding off course, which helps to ensure the sensing effect of the sensor and the sensing metal block.

[0011] Preferably, a docking cylinder shaft is provided on the side wall of the mounting box at the connection point with the telescopic spring. One end of the telescopic spring is connected to the end face of the docking cylinder shaft, and the steel wire rope passes through the docking cylinder shaft. The docking cylinder shaft serves two purposes: firstly, it connects to the spring, and secondly, it limits the movement of the steel wire rope entering the mounting box, preventing it from shifting or tilting.

[0012] Preferably, the natural length of the telescopic spring is the same as the distance from the docking cylinder shaft to the binding shaft. When the slide is pulled by the wire rope, the telescopic spring is compressed. When the foot pedal is released, the spring force pushes the slide back to its original position, thus ensuring that the automatic disconnection function can be achieved when the foot pedal is released after the sensor switch is turned on.

[0013] Preferably, a through hole is provided in the middle of the binding shaft. The steel wire rope can pass through the through hole and be wrapped and bound, which can limit its movement in the upper and lower directions.

[0014] Preferably, the mounting box has two mounting glands on the outer wall where the wire rope enters. The mounting glands facilitate installation of the mounting box inside the control box.

[0015] The present invention adopts the above technical solution and has the following technical effects compared with the prior art: The split-type inductive foot switch device provided by this utility model separates the sensor and the foot pedal. The sensor is installed separately in a box that can be installed in a control box. This split structure can achieve the functions of the previous device while completely protecting the sensor from the influence of external climate, greatly extending the service life of the device and making subsequent maintenance and replacement very convenient. By setting a telescopic spring, when the foot pedal is stepped on, the slide is pulled by the steel wire rope, and the telescopic spring is compressed. When the foot pedal is released, the elastic force of the telescopic spring pushes the slide back to its original position, thus ensuring that the inductive switch can automatically disconnect when the foot pedal is released after it is turned on.

Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0019] In some embodiments, such as Figure 1 , Figure 2 and Figure 3 As shown, an innovatively designed split-type inductive foot switch device is provided. The device mainly consists of a base plate 1, a foot pedal 17, a mounting box 12, and a steel wire rope 13. Specifically, the foot pedal 17 is suspended above the base plate 1, ensuring flexibility and convenience during operation. A support plate B16 is carefully designed and installed on both sides of the top surface of the base plate 1, and a rotating shaft 2 is positioned between these two support plates B16. The two ends of the rotating shaft 2 are connected to the two support plates B16 via bearings A15, thus enabling smooth rotation of the rotating shaft 2. Furthermore, the rotating shaft 2 also passes through the foot pedal 17, ensuring stable rotation of the foot pedal 17 during operation.

[0020] Furthermore, the top surface of the base plate 1 is equipped with a pair of support plates A14, with a roller 20 cleverly positioned between them. The roller 20 further enhances the operational flexibility of the foot pedal 17. Particularly noteworthy is the connector 3 located at the end of the foot pedal 17 near the roller 20. This connector 3 connects to the steel wire rope 13, enabling linkage between the foot pedal 17 and the mounting box 12. This ensures precise response and achieves the desired sensing effect during operation. Through this ingenious design, the split-type inductive foot switch device is not only structurally robust and easy to operate, but also effectively improves the user experience.

[0021] A sliding plate 10 is installed at one end of the inner bottom surface of the mounting box 12. A sensing metal block 8 is cleverly embedded in the top side of the sliding plate 10 for specific sensing functions. Simultaneously, a binding shaft 9 is securely installed in the central area of ​​the top of the sliding plate 10 for effectively binding and securing the steel wire rope 13. A high-sensitivity sensor 7 is installed on the inner bottom surface of the mounting box 12 at a position precisely aligned with the sensing metal block 8. The sensor 7 can be selected as an inductive proximity switch to ensure accurate and rapid detection of position changes in the metal block 8. Furthermore, the sensor 7 is reliably connected to a relay signal in the equipment's control box via a dedicated circuit, thereby enabling real-time monitoring and precise control of the equipment's operating status, ensuring stable operation and efficient operation of the entire system.

[0022] One end of the wire rope 13 is securely connected to the connector 3, and the other end passes around the bottom of the roller 20, ensuring a smooth path, and continues through the side wall of the mounting box 12. The other end of the wire rope 13 is tightly connected to the binding shaft 9 to ensure the stability of the entire system. A telescopic spring 11 is fitted on the section of the wire rope 13 between the mounting box 12 and the binding shaft 9 to provide necessary elasticity and cushioning. One end of the telescopic spring 11 is securely connected to the shaft of the binding shaft 9, and the other end is connected to the side wall of the mounting box 12 to ensure that the spring remains stable during extension and contraction. In addition, two mounting glands 5 are carefully designed and provided on the outer side wall of the mounting box 12 where the wire rope 13 enters, to facilitate the fixing and adjustment of the mounting box 12, further improving the safety and reliability of the entire device.

[0023] When in use, after stepping on the foot pedal 17, the steel wire rope 13 is stretched, causing the slide plate 10 to move forward a certain distance, bringing the sensing metal block 8 closer to the sensor 7. The telescopic spring 11 inside the mounting box 12 is compressed and tightened. At this time, after the sensor 7 senses the sensing metal block 8, the relay in the control box is activated, thereby achieving the purpose of controlling the operation of the equipment. When the foot is released from the foot pedal 17, the steel wire rope 13 retracts, the telescopic spring 11 rebounds, pushing the slide plate 10 back to the starting position, and the sensing metal block 8 also moves away from the sensor 7. The relay in the control box is also disconnected, and the equipment stops operating.

[0024] In some specific embodiments, such as Figure 2 and Figure 5As shown, each end of the roller 20 has a connecting shaft 2002. Each of these connecting shafts 2002 is connected to two support plates B14 via a bearing B18. Furthermore, a groove 2001 is specially designed in the middle of the roller 20. The depth and width of this groove 2001 precisely match the diameter of the wire rope 13. This design effectively limits movement, preventing the wire rope from slipping or shifting during operation, thus ensuring the stability and safety of the entire system.

[0025] A vertical plate 4 is installed on the top surface of the base plate 1, adjacent to the roller 20. This plate 4 features a carefully designed through-hole to allow the wire rope 13 to pass smoothly through. Specifically, after passing through the through-hole in the plate 4, the wire rope 13 extends from the bottom of the roller 20. This ingenious design provides a crucial limiting function for the wire rope 13, effectively preventing unnecessary bending or stretching during use. This avoids any interference from these adverse factors on the wire rope 13 connected to the roller 20. This design not only improves the stability of the wire rope 13 during tensioning but also ensures the stable operation of the entire system, extends the equipment's service life, and improves work efficiency.

[0026] In some specific embodiments, such as Figure 3 and Figure 4 As shown, a groove 6 is carefully cut into the bottom of each of the two inner side walls of the mounting box 12. The two ends of the slide plate 10 slide into these two grooves 6 respectively. By cleverly setting the grooves within the mounting box, the slide plate can smoothly slide along a pre-set, fixed trajectory. The length of the slide plate 10 is precisely designed so that the distance between it and the inner walls of the two grooves 6 is exactly the same, effectively preventing any deviation of the slide plate 10 during sliding. This not only ensures the stable operation of the slide plate 10 but also helps to ensure that the sensing effect between the sensor 7 and the sensing metal block 8 reaches its optimal state, thereby improving the overall performance and reliability of the device.

[0027] In some specific implementation cases, such as Figure 3 and Figure 6As shown, a docking cylinder shaft 21 is installed on the side wall of the mounting box 12 at the position where it connects to the telescopic spring 11. One end of this docking cylinder shaft 21 is tightly connected to the end face of the telescopic spring 11, ensuring a stable connection between the two. Meanwhile, the steel wire rope 13 is cleverly designed to run through the entire docking cylinder shaft 21. On the one hand, it effectively connects the telescopic spring 11, ensuring the normal functioning of the spring's extension and contraction; on the other hand, it also plays a crucial role in limiting the steel wire rope 13 as it enters the mounting box 12, preventing it from shifting or tilting during use, thereby ensuring the stability and reliability of the entire device.

[0028] Furthermore, it is worth mentioning that the natural length of the telescopic spring 11 is carefully designed to be exactly the same as the distance between the docking cylinder shaft 21 and the binding shaft 9. This design not only ensures that the spring can maintain optimal mechanical performance during the telescopic process, but also further improves the working efficiency and stability of the entire device.

[0029] When the slide plate 10 is pulled by the traction force of the steel cable 13, the connected telescopic spring 11 is subjected to corresponding pressure, resulting in compression deformation. At this time, the entire device is in a state of tension. Subsequently, when the operator releases the foot pedal 17, the previously compressed telescopic spring 11 quickly releases its stored elastic potential energy, generating a forward elastic force that smoothly pushes the slide plate 10 back to its initial position. This process not only ensures that the sensor switch can respond normally when it is on, but more importantly, even after the foot pedal 17 is released, the system can still achieve a reliable automatic disconnection function by relying on the reset action of the telescopic spring 11, thereby avoiding potential risks caused by improper operation.

[0030] Furthermore, a through hole 901 is specially designed in the middle of the binding shaft 9, which facilitates the winding of the wire rope 13. The wire rope 13 can smoothly pass through the through hole 901 and be orderly wound and bound on the binding shaft 9. This design not only makes the wire rope more secure, but also effectively limits the movement of the slide plate 10 during its up and down movement, ensuring that the slide plate 10 runs smoothly within the predetermined track and avoiding excessive movement or deviation from the track, thereby further improving the safety and stability of the entire device.

[0031] In summary, this utility model separates the sensor 7 from the foot pedal and installs the sensor 7 in a separate box, which can be installed in the control box. This split structure not only achieves the functions of the previous equipment but also completely protects the sensor 7 from the influence of external climate, greatly extending the service life of the equipment and making subsequent maintenance and replacement very convenient. By setting a telescopic spring 11, when the foot pedal 7 is stepped on, the slide plate 10 is pulled by the wire rope 13, and the telescopic spring 11 is compressed. When the foot pedal 7 is released, the elastic force of the telescopic spring 13 pushes the slide plate 10 back to its original position, thus ensuring that the sensor switch can automatically disconnect when the foot pedal 7 is released after it is turned on.
