Description

Technical Field

[0001] This utility model relates to the field of foot switch technology, specifically a connector that facilitates the maintenance of foot switches. Background Technology

[0002] A foot switch is a switch that controls the on / off state of a circuit by stepping on it. It is typically used in control circuits where the hands cannot reach, thus replacing the hands for operation. The working principle of a foot switch is based on its internal switching mechanism. When the user steps on the pedal, the pedal moves downward, triggering the internal mechanical connection to close or open the switch. This opening and closing process can activate the circuit, start or stop the equipment, and perform other operations.

[0003] For example, patent application number 201711232392.4 published on the China Patent Network, entitled "Multifunctional Foot Switch," describes a device that includes a fixing component for forming the outer shell of the foot switch and for mounting and fixing other components; a mechanical control component for generating a switch signal based on the user's pedaling action; an electronic control component electrically connected to the mechanical control component; the electronic control component for setting the operating mode of the foot switch, detecting the switch signal from the mechanical control component, processing the switch signal, and transmitting it to the main device; and a power supply electrically connected to the electronic control component to provide operating voltage. This multifunctional foot switch allows for convenient and flexible switching control, catering to users with different operating habits and various working conditions.

[0004] However, the existing connection method between the pedal and the body of the foot switch is relatively simple, mainly through hinged connection by a fixed pin. When internal maintenance is required, the connecting parts on both sides of the pedal need to be pulled to disengage them from the pin. This process is not only time-consuming but also requires a lot of force, increasing the difficulty of maintenance. During repeated disassembly and assembly, the connecting parts may be damaged due to frequent pulling and friction, resulting in an unstable connection or failure. This not only affects the normal use of the foot switch but may also cause safety hazards.

[0005] Therefore, it is necessary to redesign and modify the connectors to facilitate the maintenance of the foot switch. Utility Model Content

[0006] To address the problems mentioned in the background section, the present invention aims to provide a connector that facilitates the maintenance of foot switches. This connector offers the advantage of easy disassembly and repair, solving the problem that existing foot switch connections between the pedal and the body are relatively simple, primarily relying on hinged connections via fixed pins. When internal maintenance is required, the connectors on both sides of the pedal must be pulled to disengage from the pins. This process is time-consuming and requires considerable force, increasing the difficulty of maintenance. Furthermore, repeated disassembly and reassembly can damage the connectors due to frequent pulling and friction, leading to weak or failed connections. This not only affects the normal operation of the foot switch but may also pose safety hazards.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a connector for easy maintenance of a foot switch, including a base;

[0008] A foot pedal located on top of the machine base;

[0009] When the pedal is stepped on and lowered, it can trigger the base to generate an electrical signal. A connecting frame is provided at the bottom of the pedal. The left and right sides of the connecting frame are movably connected to the shafts via bearings. The bottom end of the shafts passes through the connecting frame and extends to the bottom of the connecting frame. A rotating shaft plate located at the bottom of the connecting block is fixedly connected to the surface of the shaft. Pins are fixedly connected to the left and right sides of the base. The end of the rotating shaft plate away from the shaft swings to the outside of the base and fits on the surface of the pin. The pin is slidably connected to the rotating shaft plate. The interior of the connecting frame is provided with a structure for controlling the rotation of the shaft.

[0010] As a preferred embodiment of this utility model, the structure for controlling the rotation of the shaft includes a force-bearing plate fixedly connected to the surface of the shaft. An opening is provided on the side of the connecting frame away from the machine base. A driving component is disposed inside the opening. The driving component is slidably connected to the opening. A shift fork is fixedly connected to one end of the driving component located inside the connecting frame. A pull rod is fixedly connected to the surface of the shift fork. The pull rod extends from the side away from the shift fork to the side of the force-bearing plate and can contact the force-bearing plate. When the driving component pulls the shift fork to move outward from the opening, the pull rod can be used to squeeze the force-bearing plate to swing.

[0011] As a preferred embodiment of this utility model, the driving component is U-shaped and elastic. A positioning block is fixedly connected to the outer side of the driving component. The side of the positioning block away from the driving component extends to the outer side of the connecting frame and can be inserted into the connecting frame. During the process of the driving component deforming inward, it can carry the positioning block away from the connecting frame.

[0012] As a preferred embodiment of this utility model, bolts are provided on both sides of the bottom of the connecting frame, the top of the bolts penetrates the connecting frame and extends into the interior of the pedal, and the bolts are threadedly connected to the pedal.

[0013] In a preferred embodiment of this invention, upright plates are fixedly connected to both sides inside the connecting frame. The upright plates are used to support the connecting frame. The upright plates are located on both sides of the driving component, and the driving component is slidably connected to the upright plates.

[0014] As a preferred embodiment of this utility model, side plates are fixedly connected to both the left and right sides of the connecting frame, and the top of the side plates contacts the bottom of the pedal, so that the side plates can cover the interior of the connecting frame.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] 1. This utility model, through the design of the connecting frame and shaft at the bottom of the pedal, and the rotating plate fixed on the surface of the shaft, makes the connection between the pedal and the base more stable, while maintaining sufficient flexibility to adapt to different operating needs. Moreover, the swingable rotating plate can be quickly separated from the rotating shaft, so users can disassemble the pedal to achieve the effect of quick maintenance of the base.

[0017] 2. This utility model, by setting up a structure for controlling the rotation of the shaft, enables quick assembly and disassembly between the pedal and the base. This design greatly simplifies the maintenance process, reduces maintenance difficulty and cost, and allows users to easily control the rotation of the shaft by pulling the drive component, thereby separating the pedal from the base.

[0018] 3. This utility model, through the U-shaped design and elastic characteristics of the driving component, as well as the plug-in design of the positioning block and the connecting frame, ensures that the driving component can be firmly fixed on the connecting frame when it is not pulled, preventing accidental detachment or loosening. When the pedal needs to be disassembled, the user can press the driving component to deform it inward, thereby disengaging the positioning block from the connecting frame, which makes the disassembly process simpler and faster.

[0019] 4. The bolt design at the bottom of the connecting frame not only strengthens the connection between the pedal and the connecting frame, but also provides additional fixing points, making the entire connection more stable and reliable. The threaded connection design between the bolt and the pedal allows users to easily adjust the height or position of the pedal as needed to adapt to different operating environments or requirements.

[0020] 5. This utility model provides additional support for the connecting frame through the design of the upright plate inside the connecting frame, which enhances its structural strength and stability. The upright plate is located on both sides of the driving component and is slidably connected to the driving component, ensuring that the driving component can remain stable during the sliding process and will not affect the disassembly effect due to shaking or displacement.

[0021] 6. The side plate design on the left and right sides of the connecting frame not only protects the internal structure of the connecting frame from external interference or damage, but also improves the neatness and aesthetics of the entire connector. The top of the side plate contacts the bottom of the pedal, which further enhances the connection stability between the pedal and the connecting frame and prevents debris or dust from entering the interior of the connecting frame, thereby extending the service life of the connector.

[0027] 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.

[0028] like Figures 1 to 4 As shown, the present invention provides a connector for easy maintenance of a foot switch, including a base 1;

[0029] A foot pedal 2 is installed on top of the base 1;

[0030] When the pedal 2 is stepped down, it can trigger the base 1 to generate an electrical signal. The bottom of the pedal 2 is provided with a connecting frame 3. The left and right sides of the connecting frame 3 are movably connected to the shaft 4 through bearings. The bottom end of the shaft 4 passes through the connecting frame 3 and extends to the bottom of the connecting frame 3. The surface of the shaft 4 is fixedly connected to the rotating shaft plate 5 located at the bottom of the connecting block. The left and right sides of the base 1 are fixedly connected to the pin 6. The end of the rotating shaft plate 5 away from the shaft 4 swings to the outside of the base 1 and is sleeved on the surface of the pin 6. The pin 6 and the rotating shaft plate 5 are slidably connected. The inside of the connecting frame 3 is provided with a structure for controlling the rotation of the shaft 4.

[0031] refer to Figure 4 The structure for controlling the rotation of the shaft 4 includes a force plate 7 fixedly connected to the surface of the shaft 4. An opening 8 is provided on the side of the connecting frame 3 away from the base 1. A driving member 9 is provided inside the opening 8. The driving member 9 is slidably connected to the opening 8. A shift fork 10 is fixedly connected to one end of the driving member 9 inside the connecting frame 3. A pull rod 11 is fixedly connected to the surface of the shift fork 10. The pull rod 11 extends to one side of the force plate 7 away from the shift fork 10 and can contact the force plate 7. When the driving member 9 pulls the shift fork 10 to move outward from the opening 8, the pull rod 11 can be used to squeeze the force plate 7 to swing.

[0032] As a technical optimization of this utility model, by setting a structure for controlling the rotation of the shaft 4, the connector enables quick assembly and disassembly between the pedal 2 and the base 1. This design greatly simplifies the maintenance process, reduces maintenance difficulty and cost, and allows users to easily control the rotation of the shaft 4 by pulling the drive component 9, thereby separating the pedal 2 from the base 1.

[0033] refer to Figure 4 The driving component 9 is U-shaped and elastic. A positioning block 12 is fixedly connected to the outside of the driving component 9. The side of the positioning block 12 away from the driving component 9 extends to the outside of the connecting frame 3 and can be inserted into the connecting frame 3. During the process of the driving component 9 deforming inward, it can carry the positioning block 12 away from the connecting frame 3.

[0034] As a technical optimization of this utility model, the U-shaped design and elastic properties of the driving component 9, as well as the plug-in design of the positioning block 12 and the connecting frame 3, ensure that the driving component 9 can be firmly fixed on the connecting frame 3 when it is not pulled, preventing accidental detachment or loosening. When it is necessary to disassemble the pedal 2, the user can press the driving component 9 to deform it inward, thereby disengaging the positioning block 12 from the connecting frame 3, which makes the disassembly process simpler and faster.

[0035] refer to Figure 4 Bolts 13 are provided on both sides of the bottom of the connecting frame 3. The top of the bolt 13 passes through the connecting frame 3 and extends into the interior of the pedal 2. The bolt 13 is threadedly connected to the pedal 2.

[0036] As a technical optimization of this utility model, the design of bolt 13 at the bottom of the connecting frame 3 not only strengthens the connection strength between the pedal 2 and the connecting frame 3, but also provides an additional fixing point, making the entire connecting part more stable and reliable. The threaded connection design between bolt 13 and pedal 2 allows users to easily adjust the height or position of pedal 2 as needed to adapt to different operating environments or requirements.

[0037] refer to Figure 4Both sides of the connecting frame 3 are fixedly connected to the upright plate 14. The upright plate 14 is used to support the connecting frame 3. The upright plate 14 is located on both sides of the driving component 9, and the driving component 9 is slidably connected to the upright plate 14.

[0038] As a technical optimization of this utility model, the design of the upright plate 14 inside the connecting frame 3 provides additional support for the connecting frame 3, enhancing its structural strength and stability. The upright plate 14 is located on both sides of the driving component 9 and is slidably connected to the driving component 9, ensuring that the driving component 9 can remain stable during the sliding process and will not affect the disassembly effect due to shaking or displacement.

[0039] refer to Figure 2 Side plates 15 are fixedly connected to the left and right sides of the connecting frame 3. The top of the side plate 15 contacts the bottom of the pedal 2, and the side plate 15 can cover the inside of the connecting frame 3.

[0040] As a technical optimization of this utility model, the design of the side plates 15 on the left and right sides of the connecting frame 3 not only protects the internal structure of the connecting frame 3 from external interference or damage, but also improves the neatness and aesthetics of the entire connector. The top of the side plate 15 contacts the bottom of the pedal 2, which further enhances the connection stability between the pedal 2 and the connecting frame 3 and prevents debris or dust from entering the interior of the connecting frame 3, thereby extending the service life of the connector.

[0041] The working principle and usage process of this utility model are as follows: When the user steps on pedal 2, pedal 2 will descend and trigger the base 1 to generate an electrical signal. This electrical signal can further control the start or stop of related equipment. In order to facilitate maintenance, the connector is designed with a mechanism that is easy to disassemble and assemble. When it is necessary to disassemble pedal 2, the driver 9 can be pressed first, so that the driver 9 deforms inward by elastic force and carries the positioning block 12 away from the connecting frame 3. Then, the driver 9 is pushed to move into the connecting frame 3. At this time, the pull rod 11 can disengage from the force plate 7, so that the force plate 7 drives the shaft 4 and the rotating shaft plate 5 to rotate, thereby disengaging the rotating shaft plate 5 from the pin 6, realizing the separation of pedal 2 from the base 1. When pedal 2 carries the connecting frame 3 away from the base 1, the user can carry out maintenance on the base 1.

[0042] In summary, this foot switch maintenance-friendly connector, through the design of the connecting frame 3 and shaft 4 at the bottom of the pedal 2, and the rotating plate 5 fixed on the surface of the shaft 4, makes the connection between the pedal 2 and the base 1 more stable, while maintaining sufficient flexibility to adapt to different operating needs. Moreover, the swingable rotating plate can quickly separate from the shaft, so the user can disassemble the pedal 2 to achieve the effect of quick maintenance of the base 1.
