The utility model relates to the technical field of water saving of faucets, and discloses a water-saving faucet shell which comprises an outer shell, a protection assembly is fixedly connected to the outer side of the outer shell, a water stop assembly is arranged in the outer shell, and a flow guide assembly is fixedly connected to one end of the outer shell. According to the water-saving faucet shell, through the arrangement of the water stop assembly and the flow guide assembly, when the water-saving faucet shell is used, water flow impacts a connecting plate, so that an extrusion spring is in a compressed state, a water stop plug moves, the water flow enters a mounting box, and a flow guide plate in the mounting box combs and guides the water flow, so that water outlet is more uniform and gentle; when the faucet is closed, the spring is extruded to drive the connecting plate and the water stop plug to reset, and the water stop plug is tightly attached to a water flowing pipeline, so that the water flow is completely blocked, it is ensured that the faucet does not drip water or leak water, and water resource waste caused by water leakage and water dripping is reduced.

The utility model discloses a transmission assembly, a power transmission device and a vehicle, the transmission assembly comprises a power shaft, a driven gear, a transmission part and a buffer part, a driving gear is arranged on the power shaft, the driving gear is suitable for being meshed with a power output device, a matching section is formed on the power shaft, and the driven gear is arranged on the matching section in a sleeving mode; the driven gear can rotate relative to the matching section, a first circumferential matching part is arranged on the driven gear, the transmission part is arranged on the matching section and rotates synchronously with the power shaft, a second circumferential matching part is arranged on the transmission part, and the second circumferential matching part and the first circumferential matching part are arranged correspondingly. When the driven gear moves in the circumferential direction relative to the matching section, the first circumferential matching part and the second circumferential matching part get close to each other or get away from each other, the buffering piece is connected between the first circumferential matching part and the second circumferential matching part, and the buffering capacity of the transmission assembly can be improved.

This invention relates to the field of centrifugal fans, specifically disclosing a portable energy-saving electric fan and its usage method. The fan includes a housing with a grille and a fan installed inside the housing. The fan's outlet is aligned with the grille. The top of the housing has an opening through which the fan can extend. The fan's outer casing is divided into a fixed part and at least one movable part. The movable part is movable relative to the fixed part. When the movable and fixed parts are separated, maintenance tools can be inserted into the casing to inspect the inner wall and impeller. This invention allows the fan to be lifted from the housing for easy maintenance. Furthermore, the fan's outer casing can be divided into a fixed part and at least one movable part, and the fixed and movable parts can be fixed to the fixed part without connecting parts, only by a retaining element inside the housing, facilitating maintenance and return to its original position after maintenance.

The utility model discloses a kind of mute door groups in the technical field of acoustics engineering, including door frame, the door frame inside is connected with door panel by hinged installation, first lock tongue accommodating slot is opened in the right edge of the door panel inside, the position of the door frame corresponding to door panel first lock tongue accommodating slot is equipped with second lock tongue accommodating slot in its and the inside surface of door panel bonding;The door panel inside is equipped with a transmission groove with specific bending line, by setting transmission groove, transmission ball and other structures between door frame and door panel and reasonable layout, reach accurate stable locking purpose.Compared with traditional mechanical lock, avoid rebound sound, do not destroy quiet atmosphere, compared with magnetic attraction lock, not affected by environmental humidity and frequent opening and closing, not demagnetization, guarantee door lock suction force and security performance.When door panel is closed, trigger slider drives lock tongue to insert into slot through transmission ball, reset spring helps reset, make locking reliable, convenient operation, improve door group safety, durability and practicality.

This utility model relates to the field of curtain machine technology and discloses a positioning mechanism for a curtain machine. The positioning mechanism is mounted on a movable body on a curtain track. The positioning mechanism includes a suspension part and two sets of longitudinal pressure rollers. The suspension part is a roller rotatably mounted on the movable body and is suspended from the curtain track. The longitudinal pressure rollers are mounted on the movable body and configured to abut against the curtain track upwards under elastic force. The two sets of longitudinal pressure rollers are positioned at a height difference from the suspension part, and the two sets of longitudinal pressure rollers are located in front of and behind the suspension part along the length of the guide rail body, so that the suspension part and the two sets of longitudinal pressure rollers are triangularly distributed. The two sets of longitudinal pressure rollers and the suspension part clamp the curtain track longitudinally, thereby limiting the up-and-down swaying of the movable body, greatly enhancing the stability of the movable body on the curtain track, enabling the movable body to operate smoothly and steadily, and ensuring the reliability of the curtain opening and closing operation.
