Abstract
Description
Technical Field
[0001] This utility model relates to the field of proximity switch technology, and in particular to a novel inductive proximity switch. Background Technology
[0002] Currently, inductive proximity switches are widely used in various industrial automation equipment, playing a crucial role, especially in detecting the proximity and distance of objects. However, existing inductive proximity switches typically require selecting an appropriate wiring length based on the distance to the object. This is because excessively long wiring can not only cause tangling and affect aesthetics but may also lead to unexpected circuit malfunctions, thereby impacting the stability and safety of the system.
[0003] For example, Chinese utility model patent application number 202420344107.7 discloses an inductive proximity switch, including a proximity switch, a connecting wire with a plug fixedly connected to the top of the proximity switch, a storage box fitted near the plug of the connecting wire, a connecting plate fixedly connected to the side wall of the storage box, a rotating shaft rotatably connected inside the storage box, and the connecting wire wound around the rotating shaft. The top and bottom of the storage box are respectively drilled with an upper through hole and a lower through hole. With the above-mentioned adjustable structure, when installing the proximity switch in different environments, the proximity switch can be fixed first, and then the shaft can be rotated by turning the handle, so that the connecting wire can be extended and adjusted from the lower through hole. After adjusting to a suitable length, the handle can be fixed to prevent the shaft from rotating back. The connecting plate on the storage box can be fixed to a load-bearing object near the power source with bolts, and then the plug can be connected to the power source. This effectively achieves the effect of freely adjusting the wiring length according to the on-site use environment and the distance of the object, achieving the optimal use length.
[0004] Although the above-mentioned device can retract and discharge the cable, avoiding the problem of excessively long or messy cables, and allows for free adjustment, in actual use, manual operation makes it difficult to ensure that the cable is wound evenly. At the same time, the cable is prone to pile up in a certain area on the retractor due to uneven distribution of gravity or tension, which makes it impossible to retract and discharge the cable smoothly. Therefore, a new type of inductive proximity switch is proposed to solve the above problems. Utility Model Content
[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a novel inductive proximity switch.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: a novel inductive proximity switch, comprising a proximity switch body, one end of which is fixedly connected to a wire, and one end of which is fixedly connected to a plug. A storage box is fitted on the outer wall of the wire near the plug. An auxiliary component is provided on the front of the storage box. Two support bases and two support plates are fixedly connected to the inner bottom surface of the storage box. A take-up roller is rotatably connected to the opposite side of the two support bases. A synchronization component is provided at one end of the take-up roller. A drive rod is fixedly connected to the other end of the take-up roller. A reciprocating rod is rotatably connected to the opposite side of the two support plates. A reciprocating groove is provided on the outer wall of the reciprocating rod. A collar is slidably connected to the outer wall of the reciprocating rod. An actuating component and a guide component are provided on the collar. Fixed components are provided on both sides of the storage box.
[0007] The proximity switch body is the core component of the entire device, responsible for sensing the approach of a target object and transmitting a signal. A wire connects the proximity switch body and the plug, transmitting current or signals to the switch or other devices. The plug serves as the power connection, transmitting current from an external power source to the proximity switch body and related equipment. The storage box acts as a container for the wire and other components, protecting the wire from damage and providing a place for easy access and storage. The internal design of the storage box includes support bases, support plates, and other components to secure the wire, ensuring smooth access. The take-up roller is responsible for retracting or releasing the wire; by winding around the wire, it effectively retracts and releases it. When adjusting the wire length, rotating the take-up roller allows for easy adjustment.
[0008] As a further description of the above technical solution:
[0009] The auxiliary component includes a groove formed on the front of the storage box, and two auxiliary rollers are rotatably connected between the two sides of the inner wall of the groove.
[0010] The wire passes between the two auxiliary rollers and, as it moves, comes into contact with the outer wall of the auxiliary rollers, thereby reducing friction.
[0011] As a further description of the above technical solution:
[0012] The wire is located inside the storage box and its outer wall is wound and connected to the outer wall of the take-up roller.
[0013] As a further description of the above technical solution:
[0014] The synchronization component includes a pinion fixedly installed at one end of the take-up roller, and a toothed belt is meshed with the outer wall of the pinion.
[0015] When the take-up roller rotates, the speed of the reciprocating rod is precisely controlled by the gear set to ensure that the actuating frame moves axially a fixed distance for each turn of the cable, thus achieving layered and uniform winding.
[0016] As a further description of the above technical solution:
[0017] The inner wall of the toothed belt is meshed with a large gear, and a connecting shaft is fixedly connected to one side of the large gear.
[0018] One end of the connecting shaft rotates through the interior of one of the support plates and is fixedly connected to the reciprocating rod.
[0019] As a further description of the above technical solution:
[0020] The actuating assembly includes a slide column and an actuating bracket. The top of the slide column is fixedly installed on the inner top surface of the collar, and the bottom of the actuating bracket is fixedly installed on the top of the collar.
[0021] The toggle mechanism adjusts the specific position of the cable, and through synchronous movement with the reciprocating rod, ensures the cable is accurately positioned during retraction and extension.
[0022] As a further description of the above technical solution:
[0023] The guide assembly includes a fixed rod fixedly installed at the bottom of the collar, a slip ring fixedly connected to the bottom end of the fixed rod, and a guide rod slidably connected to the inner wall of the slip ring.
[0024] The two ends of the guide rod are fixedly connected to the opposite sides of the two support plates, and the guide assembly restricts the collar to slide only along the axial direction of the guide rod, eliminating radial sway.
[0025] As a further description of the above technical solution:
[0026] The fixing component includes two fixing blocks, which are respectively fixedly installed on both sides of the storage box, and fixing bolts are threaded through the top of the fixing blocks.
[0027] The fixing assembly securely installs the storage box in the appropriate position using two fixing blocks and fixing bolts, ensuring the stability and safety of the entire device and playing a role in maintaining structural integrity and preventing the storage box from shifting.
[0028] This utility model has the following beneficial effects:
[0029] 1. Compared with existing technologies, this new inductive proximity switch, through the coordinated use of structures such as a reciprocating rod, a synchronization component, a guide component, and an actuating component, ensures that the wire is evenly wound onto the take-up roller. This allows the actuating frame to move back and forth precisely to adjust the position of the wire, ensuring that the wire is neatly wound. This effectively avoids problems such as tangled or knotted wires, and keeps the wire neatly and orderly stored on the take-up roller, preventing messy exposed wires and improving the aesthetic appearance of the system.
[0030] 2. Compared with existing technologies, this new inductive proximity switch, through a storage box, take-up roller, drive rod, and auxiliary components, can smoothly drive the take-up roller to rotate, easily untangling the wire and quickly adjusting the wire length. In use, the proximity switch body can be placed in an appropriate position as needed, and it can work normally after plugging in the power supply, improving the efficiency of installation and adjustment. At the same time, the rotation of the auxiliary roller reduces the friction between the wire and the equipment, thereby reducing wear and significantly improving the service life and reliability of the equipment.

[0038] 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.
[0039] Reference Figure 1-5 This utility model provides a novel inductive proximity switch: It includes a proximity switch body 1, with a wire 2 fixedly connected to one end of the body 1, and a plug 3 fixedly connected to the other end of the wire 2. A storage box 4 is fitted onto the outer wall of the wire 2 near the plug 3. An auxiliary component is provided on the front of the storage box 4. Two support bases 5 and two support plates 6 are fixedly connected to the inner bottom surface of the storage box 4. A take-up roller 7 is rotatably connected to the opposite side of the two support bases 5. A synchronization component is provided at one end of the take-up roller 7, and a drive rod 8 is fixedly connected to the other end. A reciprocating rod 9 is rotatably connected to the opposite side of the two support plates 6. The outer wall of the reciprocating rod 9 is open... The device includes a reciprocating groove 10, a collar 11 that slides on the outer wall of the reciprocating rod 9, an actuating component and a guiding component on the collar 11, and fixing components on both sides of the storage box 4. The proximity switch body 1 is the core component of the entire device, responsible for sensing the approach of the target object and transmitting a signal. The wire 2 connects the proximity switch body 1 and the plug 3, responsible for transmitting current or signals to the switch or other devices. The plug 3 serves as the power connection terminal, responsible for transmitting current from the external power source to the proximity switch body 1 and related devices. The storage box 4 serves as a container for the wire 2 and other components, protecting the wire 2 from damage and providing a place for the wire 2 to be stored and stored freely. The internal design of the storage box 4 includes components such as the support base 5 and the support plate 6 to fix the wire 2, ensuring the smooth winding and unwinding of the wire 2. The take-up roller 7 is responsible for winding or releasing the wire 2. By winding around the wire 2, it plays the role of winding and unwinding the wire 2. When it is necessary to adjust the length of the wire 2, rotating the take-up roller 7 can complete the operation smoothly. Through the coordinated use of structures such as the reciprocating rod 9, the synchronization component, the guide component, and the actuating component, it can be ensured that the wire 2 can be evenly wound onto the take-up roller 7. This allows the actuating frame 19 to move back and forth to accurately adjust the position of the wire 2, ensuring that the wire 2 is neatly wound. This effectively avoids problems such as the wire 2 being tangled or knotted, and keeps the wire 2 neatly and orderly stored on the take-up roller 7, preventing the wire 2 from being messy and exposed, and improving the aesthetic appearance of the system.
[0040] The auxiliary components include a groove 12 on the front of the storage box 4. Two auxiliary rollers 13 are rotatably connected between the two sides of the inner wall of the groove 12. The wire 2 passes through the position between the two auxiliary rollers 13. When the wire 2 moves, it can contact the outer wall of the auxiliary roller 13, thereby reducing friction. The wire 2 is located inside the storage box 4 and its outer wall is wound and connected to the outer wall of the take-up roller 7.
[0041] The synchronization component includes a small gear 14 fixedly installed at one end of the take-up roller 7. A toothed belt 15 is meshed with the outer wall of the small gear 14. When the take-up roller 7 rotates, the speed of the reciprocating rod 9 is precisely controlled by the gear set to ensure that the actuating frame 19 moves axially a fixed distance for each turn of the cable, so as to achieve layered and uniform winding. A large gear 16 is meshed with the inner wall of the toothed belt 15. A connecting shaft 17 is fixedly connected to one side of the large gear 16. One end of the connecting shaft 17 rotates through the interior of one of the support plates 6 and is fixedly connected to the reciprocating rod 9.
[0042] The actuating assembly includes a sliding column 18 and an actuating bracket 19. The top of the sliding column 18 is fixedly installed on the inner top surface of the collar 11, and the bottom of the actuating bracket 19 is fixedly installed on the top of the collar 11. The actuating assembly adjusts the specific position of the wire 2. By moving synchronously with the reciprocating rod 9, it ensures that the wire 2 is accurately positioned during the winding and unwinding process. The guiding assembly includes a fixed rod 20 fixedly installed at the bottom of the collar 11. A sliding ring 21 is fixedly connected to the bottom end of the fixed rod 20. A guide rod 22 is slidably connected to the inner wall of the sliding ring 21. The two ends of the guide rod 22 are fixedly connected to the opposite side of the two support plates 6, respectively. The guiding assembly restricts the collar 11 to slide only along the axial direction of the guide rod 22, eliminating radial sway.
[0043] The fixing component includes two fixing blocks 23, which are respectively fixedly installed on both sides of the storage box 4. The top of the fixing block 23 is threaded with a fixing bolt 24. The fixing component securely installs the storage box 4 in a suitable position through the two fixing blocks 23 and the fixing bolt 24, ensuring the stability and safety of the entire device, and playing the role of maintaining structural integrity and preventing the storage box 4 from shifting.
[0044] Working principle: When installation is required, the fixing block 23 can be placed in a suitable position, and then the fixing bolts 24 can be tightened to fix the storage box 4. When the proximity switch body 1 needs to be installed, the drive rod 8 can be rotated to rotate the take-up roller 7, so that the wire 2 is unwound from the take-up roller 7, and the length of the wire 2 can be adjusted. At this time, simply place the proximity switch body 1 in the desired position and connect the plug 3 to the power supply. When the proximity switch body 1 is not in use, simply rotate the drive rod 8 in the opposite direction to rotate the take-up roller 7 in the opposite direction, so that the small gear 14 rotates synchronously. Under the action of the toothed belt 15, the large gear 16 is driven synchronously. The rotation of the gear 16 causes the connecting shaft 17 fixed to it to rotate, which in turn causes the reciprocating rod 9 to rotate synchronously. At this time, the sliding column 18 located on the collar 11 will move along the reciprocating groove 10. Under the limitation of the guide rod 22 and the sliding ring 21 on the fixed rod 20, the actuating frame 19 moves back and forth, thereby adjusting the position of the wire 2 passing through the actuating frame 19. When the wire 2 is wound up, the wire 2 is evenly wound on the take-up roller 7, so that the length can be better adjusted for the next use and it is convenient to use. At the same time, under the action of the two auxiliary rollers 13 on the slide groove 12, the auxiliary rollers 13 rotate during take-up and unwinding to reduce friction on the wire 2, thereby reducing wear and improving the service life of the device.
[0045] 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.
