Description

Technical Field

[0001] This utility model relates to the field of distribution box technology, specifically a knob structure for an FTU enclosure. Background Technology

[0002] FTU (Distribution Switchgear) is a core device in the power distribution network automation system. It is mainly used for real-time monitoring, control and management of power distribution lines and switching equipment to ensure the stable operation of the power system and rapid fault handling. The knob serves as a human-machine interface component, used to enable personnel to control the internal parameters of the FTU.

[0003] Patent publication number "CN208478210U", entitled "Waterproof Rotary Switch and Waterproof Communication Device", includes a rotary handle and an encoder. A connecting sealing section is provided between the rotary handle and the encoder. The rotary handle penetrates through a faceplate, and the connecting sealing section is sealed to the faceplate. Several mounting grooves are formed on the connecting sealing section. The above-mentioned invention also relates to a waterproof communication device, including a faceplate and the aforementioned waterproof rotary switch. The connecting sealing section is sealed to the faceplate, and the waterproof ring is interference-fitted with the wall of the faceplate. This utility model provides a waterproof rotary switch and a waterproof communication device with simple structure, low cost, and easy operation.

[0004] The aforementioned patent achieves a waterproof effect by designing multi-layer sealing rings. However, these sealing rings increase the friction between the knob handle and the housing, thereby increasing the resistance during rotation and affecting the performance. Therefore, a knob structure for the FTU housing is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a knob structure for an FTU housing to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a knob structure for an FTU enclosure, comprising a frame, a transmission rod for controlling the internal circuitry of the frame is installed inside the frame, a knob is fixedly connected to one end of the transmission rod through the interior of the frame, a limiting component for providing resistance to the rotation of the transmission rod is installed inside the transmission rod and the frame, a cover component is installed between the knob and the frame, and a sealing component is installed inside the frame.

[0007] The sealing assembly includes a rotating cover, which is mounted on the outer wall of the knob component. A first roller is mounted on one side of the rotating cover, and a second roller is mounted on the other side of the rotating cover. A semi-ring component is mounted on the outer wall of the frame, and a circular ring component is mounted between the semi-ring component and the rotating cover. A connecting assembly is mounted between the two semi-ring components.

[0008] Preferably, the limiting component includes a first spring damper, which is fixedly installed on the outer wall of the transmission rod. The telescopic end of the first spring damper is fixedly connected to a limiting block. A roller is rotatably connected inside the limiting block. A limiting inner ring is fixedly connected inside the frame to cooperate with the limiting block to provide resistance. A limiting inner ring has a limit groove inside.

[0009] Preferably, the connecting assembly includes a positioning threaded rod, which is installed inside the semi-ring, and a nut is threaded onto the outer wall of the positioning threaded rod.

[0010] Preferably, the sealing assembly includes a retaining ring, which is fixedly installed inside the frame, and a sealing ring is fixedly connected to the outer wall of the transmission rod.

[0011] Preferably, a groove is formed at the top of the frame, and the interior of the semi-ring is connected to the frame through the groove.

[0012] Preferably, the top end of the circular ring is provided with a second groove, and the interior of the semi-ring is connected to the circular ring through the second groove.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] The knob structure of this FTU enclosure protects the internal structure of the frame through the setting of a cover assembly and a sealing assembly. The cover assembly further achieves the isolation effect between the inside and outside of the frame. The cover assembly uses rollers number one and two to achieve contact with the frame and the ring component, respectively. This reduces the resistance of rotating the cover during rotation. At the same time, the cooperation between the frame, the ring component, and the rotating cover achieves preliminary sealing protection, ensuring the practicality of the knob structure.

[0015] Meanwhile, by setting the limiting components, during the rotation of the transmission rod, the limiting block on the No. 1 spring damper is restricted by the limiting groove inside the inner ring, thereby changing the length of the extension end of the No. 1 spring damper. As a result, when rotating the rotating rod, it will provide a damping sensation, and the adjustment gear can be controlled through the damping sensation. Attached Figure Description

[0023] 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.

[0024] like Figure 1 - Figure 6 As shown, this utility model provides a technical solution: a knob structure for an FTU enclosure, including a frame 1, a transmission rod 2 for controlling the internal circuit of the frame 1 is installed inside the frame 1, a knob 3 is fixedly connected to one end of the transmission rod 2 through the inside of the frame 1, a limiting component 4 for providing resistance to the rotation of the transmission rod 2 is installed inside the transmission rod 2 and the frame 1, a cover component 5 is installed between the knob 3 and the frame 1, and a sealing component 7 is installed inside the frame 1;

[0025] The sealing assembly 5 includes a rotating cover 501, which is mounted on the outer wall of the knob 3. A first roller 502 is mounted on one side of the rotating cover 501, and a second roller 503 is mounted on the other side of the rotating cover 501. A semi-ring 504 is mounted on the outer wall of the frame 1. A circular ring 505 is mounted between the semi-ring 504 and the rotating cover 501. A connecting assembly 6 is mounted between the two semi-rings 504.

[0026] The limiting component 4 includes a first spring damper 401, which is fixedly installed on the outer wall of the transmission rod 2. The telescopic end of the first spring damper 401 is fixedly connected to a limiting block 402. A roller 405 is rotatably connected inside the limiting block 402. A limiting inner ring 403 is fixedly connected inside the frame 1 to cooperate with the limiting block 402 to provide resistance. A limiting groove 404 is opened inside the limiting inner ring 403.

[0027] The connecting assembly 6 includes a positioning threaded rod 601, which is installed inside the semi-ring 504, and a nut 602 is threadedly connected to the outer wall of the positioning threaded rod 601.

[0028] The sealing assembly 7 includes a retaining ring 701, which is fixedly installed inside the frame 1, and a sealing ring 702 is fixedly connected to the outer wall of the transmission rod 2.

[0029] A groove No. 1 is provided at the top of frame 1, and the interior of semi-ring 504 is connected to frame 1 through groove No. 1.

[0030] The top of the ring part 505 has a second groove, and the interior of the semi-ring part 504 is connected to the ring part 505 through the second groove.

[0031] The frame 1 is installed in the FTU enclosure. The rotation of the knob 3 and the transmission rod 2 is controlled by rotating the cover assembly 5. The angle of the transmission rod 2 is adjusted to control the internal circuit of the frame 1, thereby controlling the internal circuit of the FTU.

[0032] To protect the transmission rod 2, a cover assembly 5 and a sealing assembly 7 are provided. The cover assembly 5 protects the transmission rod 2 and the internal adjustment FTU housing gear parts. At the same time, the sealing assembly 7 further protects the transmission rod 2 and the internal adjustment gear parts on the basis of the cover assembly 5. The sealing ring 702 and the transmission rod 2 rotate synchronously. Through the gap between the outer wall of the sealing ring 702 and the inner wall of the fixed ring 701, the sealing ring 702 will not come into contact with the inner wall of the fixed ring 701 during the rotation of the sealing ring 702, thereby protecting the internal structure of the frame 1 through the gap.

[0033] Meanwhile, in order to ensure the sealing effect of the sealing assembly 5, the rotating cover 501 is installed first, followed by the semi-ring 504. The two semi-rings 504 are connected by the limiting assembly 4. Through the cooperation between the two semi-rings 504 and the frame 1, the rotating cover 501 is restricted. At the same time, through the cooperation of the two semi-rings 504, the rotating cover 501 can rotate and connect inside the semi-rings 504.

[0034] To ensure the damping effect of rotation, the transmission rod 2 rotates due to the rotation of the rotating cover 501. During the rotation, the first spring damper 401 rotates synchronously. Due to the elastic force of the spring inside the first spring damper 401, the limiting block 402 will always be in contact with the inner wall of the limiting inner ring 403. During the rotation of the limiting block 402, under the action of the spring force, the limiting block 402 contacts the inner wall of the limiting groove, thereby limiting the limiting block 402 and the transmission rod 2. In order to ensure the service life, a roller 405 is rotatably connected inside the limiting block 402. The roller 405 reduces the friction between the roller 405 and the limiting inner ring 403, thereby ensuring the service life of the limiting component 4.

[0035] When installing the sealing assembly 5, first install the rotating cover 501, so that the inner wall of the rotating cover 501 contacts the outer wall of the knob 3. Then install the ring 505 and the half-ring 504. The half-ring 504 is installed through the first groove on the frame 1 and the second groove on the ring 505. The first groove on the frame 1 achieves the initial installation of the half-ring 504, and the second groove on the ring 505 restricts the ring 505. Then, the connection between the two half-rings 504 is achieved through the connecting assembly 6. Rotate the nut 602, and the connection between the half-rings 504 is achieved through the positioning threaded rod 601 and the nut 602. After the connection between the two half-rings 504 is achieved, the ring 505 is not easy to rotate. The first roller 502 on one side of the rotating cover 501 contacts one side of the frame 1, while the second roller 503 on the other side of the rotating cover 501 contacts the ring 505. The sealing component 7 protects the internal structure of the frame 1. The sealing component 5 further isolates the inside and outside of the frame 1. The sealing component 5 uses roller 502 and roller 503 to contact the frame 1 and the ring 505, respectively. This reduces the resistance of rotating the cover 501 during rotation. The cooperation between the frame 1, the ring 505 and the rotating cover 501 provides initial sealing protection, ensuring the practicality of the knob structure. The limiting component 4 restricts the limiting block 402 on the first spring damper 401 during rotation of the transmission rod 2. This restricts the limiting groove 404 inside the inner ring 403, changing the length of the extension end of the first spring damper 401. This provides damping when rotating the rod, and the increased damping allows for control of the adjustment gear.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended embodiments and their equivalents.
