Description

Technical Field

[0001] This utility model relates to a lockable sliding switch. Background Technology

[0002] With the continuous improvement of industrial automation and increasingly stringent safety requirements, various industrial equipment, electrical control systems, and hazardous operation equipment are placing higher demands on the safety and reliability of switch control devices. Especially in high-risk industries such as chemical, petroleum, nuclear power, mining, and high-voltage electrical engineering, maloperation of switches can lead to serious safety accidents, equipment damage, and even personal injury or death. Therefore, there is an urgent need for a switch device with a high degree of safety assurance.

[0003] Existing industrial switches mainly suffer from the following technical defects:

[0004] Traditional switches generally have shortcomings in their anti-misoperation design. Most switches are operated by direct pressing or rotating, which makes them prone to accidental operation due to unintentional touch, vibration, or other external forces. Even with protective covers, they can only prevent minor touches and cannot fundamentally eliminate misoperation. Although some switches increase the complexity of operation, such as requiring the simultaneous pressing of multiple buttons, this design can actually hinder normal operation in emergency situations and reduce ease of use. Utility Model Content

[0005] The purpose of this invention is to provide a lockable slide switch. This lockable slide switch features double locking to prevent misoperation, stable gear switching, and reliable contact.

[0006] This utility model is achieved through the following technical solution:

[0007] A lockable sliding switch includes: an upper shell and a lower shell connected to form a closed outer shell structure; a rotary lock seat rotatably disposed within the upper and lower shells; and a fixed lock seat fixedly disposed within the upper and lower shells, forming a relative rotational relationship with the rotary lock seat; the rotary lock seat is provided with a first locking plate, and the fixed lock seat is provided with a second locking plate; when the rotary lock seat is rotated to the locked position, the first locking plate and the second locking plate abut face to face, blocking the rotation of the rotary lock seat; the rotary lock seat is provided with a lock hole, and when the rotary lock seat is in the locked position, an external lock can be inserted into the lock hole and locked.

[0008] The present invention is further configured such that: a follower roller is provided at the bottom of the rotary lock seat, and a guide rail is provided on the lower shell, and the follower roller moves on the guide rail to convert the rotational motion into linear displacement.

[0009] The present invention is further configured such that: the upper shell and the lower shell are provided with a connecting part, the connecting part is an external thread structure, which is used to pass through the panel and be locked and installed by a nut.

[0010] The present invention is further configured such that the connecting part has an external thread of M12×1 or M10×0.75 specification.

[0011] The present invention is further configured such that the contact width between the first locking piece and the second locking piece is not less than 2.5 mm.

[0012] The present invention is further configured such that the guide rail is a curved guide rail, and multiple gear switching is achieved by setting different peaks and valleys.

[0013] The present invention is further configured such that: the rotating lock seat and the fixed lock seat are arranged opposite to each other, and a double locking is formed by the contact between the first lock piece and the second lock piece and the insertion of an external lock into the lock hole.

[0014] In summary, this utility model has the following beneficial effects:

[0015] 1. Dual security guarantee: The first layer of locking is formed by the mechanical contact between locking plate one and locking plate two, and the second layer of locking is formed by the external padlock in the lock hole. The dual locking mechanism ensures that the equipment cannot be operated without authorization. The contact width of the locking plate is ≥2.5mm and the shear strength of the external locking pin is >2kN. Even if an external force far exceeds the normal operation is applied, it cannot be forcibly opened, which greatly improves the safety of equipment operation.

[0016] 2. Reliable protection against misoperation: It adopts a special drive method that inserts a key into the threaded groove, requiring a specific key to operate. This effectively prevents accidental contact or misoperation by unauthorized personnel, making it particularly suitable for controlling high-risk equipment and avoiding safety accidents and economic losses caused by misoperation.

[0017] 3. Compact and durable structure: The overall size is only 21mm×11mm×24mm, which is compact and saves installation space; the upper and lower shells are connected by ultrasonic welding or snap-fit, which has good sealing performance and high protection level; the combination design of the rotary lock seat and the fixed lock seat is precise, which is not easy to wear after long-term use and has a long service life.

[0018] 4. Easy and universal installation: The connection part adopts the standard M12×1 or M10×0.75 external thread design, which is compatible with the standard panel mounting holes of 12.2±0.1mm. Installation can be completed by tightening the nut without special tools. The installation is simple and quick, and it is compatible with the mainstream panel specifications on the market.

[0019] 5. Precise and controllable operation: By following the movement of the roller on the guide rail, the rotational motion is precisely converted into linear displacement, achieving smooth sliding start; the state switching can be completed with a rotation angle of about 180°, the operating stroke is moderate, the feel is good, and the problem of difficult control of the operating force of traditional switches is avoided.

[0020] 6. Flexible switching between multiple positions: The guide rail adopts a curved design, and by setting different peaks and valleys, it can realize multiple position switching functions such as OFF→ON1→ON2. One switch can meet the control needs of multiple working states, improving the functionality and applicability of the switch.

[0021] 7. Excellent cost-effectiveness: The mechanical structure design eliminates the need for complex electronic components, resulting in low manufacturing costs; the dual locking function is integrated into a single switch, eliminating the need for additional safety devices and reducing the overall system cost; high reliability and low failure rate reduce maintenance costs.

[0026] In the description of this utility model, it should be noted that directional terms such as "up", "down", "front", "back", "left", and "right" are only for the convenience of describing and understanding this utility model, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0027] like Figures 1-3 As shown, this utility model provides a lockable sliding switch, including an upper shell 1 and a lower shell 2. The upper shell 1 and the lower shell 2 are connected by ultrasonic welding or snap-fit ​​to form a closed outer shell structure for housing and protecting the internal mechanism. A connecting part 3 is provided on the upper shell 1 and the lower shell 2. This connecting part 3 has an external thread of M12×1 or M10×0.75 specification, which is used to pass through the panel and be locked with a nut to achieve a secure installation of the switch. The overall dimensions of the switch are 21mm long × 11mm wide × 24mm high, excluding the terminal part, and it is compatible with panel mounting holes with a diameter of 12.2±0.1mm.

[0028] A rotary lock seat 4 is rotatably disposed within the upper shell 1 and the lower shell 2. The rotary lock seat 4 is a cylindrical structure that rotates on a fixed lock seat 5. The fixed lock seat 5 is fixedly disposed within the upper shell 1 and the lower shell 2, forming a relative rotational relationship with the rotary lock seat 4. A locking plate 6 is provided on the rotary lock seat 4, and a locking plate 7 is provided on the fixed lock seat 5. When the rotary lock seat 4 rotates to the locked position, locking plate 6 and locking plate 7 abut face-to-face, mechanically blocking the rotation of the rotary lock seat 4 and achieving the first level of locking function.

[0029] The rotary lock base 4 has a lock hole 8. When the rotary lock base 4 is in the locked position, the external lock can be inserted into the lock hole 8 and locked, achieving a second layer of locking function. This double locking design ensures that the switch cannot be operated without authorization, greatly improving security. When the external lock is locked, even if a torque far exceeding normal operating force is applied, the lock base cannot rotate because the contact width of the lock plate is ≥2.5mm, and the shear strength of the external lock pin with a diameter of 2.5-3.0mm is >2kN, far exceeding the normal operating force.

[0030] A follower roller 11 is provided at the bottom of the rotary lock seat 4, connected by a bearing component (details omitted here). A guide rail 12 is provided between the follower roller 11 and the lower shell 2, and the follower roller 11 moves linearly on the inner guide rail. The follower roller 11 moves along a curve, converting the rotational motion into the linear displacement of the rotary lock seat 4, thereby completing the sliding start function.

[0031] The working process of this utility model is as follows: Before power-on, the rotary lock seat 4 is in the locked position, with lock plate 6 and lock plate 7 facing each other. The external lock is inserted into the lock hole 8 and locked, the lock seat remains stationary, the rotary lock seat 4 cannot be driven, and the equipment remains in the off state. When operation is required, first remove the external lock. At this time, the lock seat can rotate clockwise by about 180°, and the threaded disc 10 drives the rotary lock seat 4 to advance along the guide rail 12, thus connecting the circuit. To disconnect, turn the key counterclockwise 180° to retract it. If it is a three-position structure, the guide rail 12 has two peaks and valleys, which sequentially achieve OFF→ON1→ON2. After the operation is completed, the rotary lock seat 4 can be returned to the locked position, and the external lock can be inserted to lock it again.

[0032] Through the above structure and working process, this utility model achieves the technical effects of dual safety locking and precise gear switching, providing an excellent switching solution for various devices that require safety control, and has broad application prospects.
