The application provides an ETSSOP20-10L lead frame and a power module. The middle part of the packaging unit of the lead frame has a base island. One side has a first pin, a second pin, a third pin, a fourth pin, a fifth pin and a sixth pin. The other side has a seventh pin, an eighth pin, a ninth pin and a tenth pin. The seventh pin, the eighth pin and the ninth pin are connected to the base island, and the remaining pins are arranged at intervals from the base island. The width of the seventh pin, the eighth pin and the ninth pin is greater than the width of the remaining pins. The distance between the first pin and the second pin, the distance between the fifth pin and the sixth pin and the distance between the tenth pin and the ninth pin are all greater than the distance between the remaining adjacent pins. The power module is packaged by the ETSSOP20-10L lead frame. The scheme of the application omits and widens some pins, meets the application requirements and ensures the heat dissipation effect, and reasonably arranges the position relationship between the base island and the specific pins to meet the dielectric requirements.

The utility model discloses an adjustable gas transmission assembly suitable for respiratory therapy equipment, the gas transmission assembly comprises a gas inlet and a gas outlet, the gas transmission assembly further comprises a first gas transmission section and a second gas transmission section, the first gas transmission section is internally provided with a first gas transmission channel communicated with the gas inlet, and the second gas transmission section is internally provided with a second gas transmission channel communicated with the gas outlet; the first gas transmission section and the second gas transmission section are telescopically connected through a communicating piece, and a communicating pipeline for communicating the first gas transmission channel and the second gas transmission channel is arranged in the communicating piece; the second gas conveying section can move relative to the first gas conveying section through the communicating piece so as to adjust the relative distance between the first gas conveying section and the second gas conveying section. According to the gas transmission assembly, the first gas transmission section and the second gas transmission section are connected through the communicating piece, and the relative position between the second gas transmission section and the first gas transmission section can be adjusted through the communicating piece according to users with different head circumference sizes, so that the wearing comfort of the gas transmission assembly is improved, and the adaptability of the gas transmission assembly is enhanced.

The utility model provides a steel rotary latch which comprises a lock box, a mounting plate, a rotary structure, a connecting handle, a rotary handle and a positioning structure, the mounting plate is fixedly mounted on the outer side of the lock box and fixedly mounted on a door plate, and the rotary structure is mounted on one side in the lock box; the connecting handle is rotationally installed on the outer side of the rotating structure, the rotating handle is fixedly installed on the top of the connecting handle, and the positioning structure is fixedly installed on the other side in the lock box. Due to the arrangement of the rotating structure, the rotating handle and the positioning structure, the risk of misoperation is low, operation is convenient, locking stability is high, and external interference is not likely to happen.

This utility model discloses an angle-adjustable steering knuckle, relating to the field of umbrella accessory technology. It includes a stop clip for connecting the umbrella pole, a base for connecting the ground pole, a toothed head, and a drive component. The stop clip is rotatably connected to the upper part of the base. A vertically formed through-cavity is provided inside the base, and the toothed head is slidably disposed within the cavity to prevent rotation. The drive component is movably sleeved on the outside of the base and is connected to the toothed head via a transmission connection. It has the ability to drive the toothed head to reciprocate and lock in a lifting and lowering motion, so that the toothed head can be limited to contact or separate from the stop clip. In the locked state, the toothed head is limited to contact the stop clip to restrict the rotation of the stop clip relative to the base. In the rotating state, the toothed head is separated from the stop clip, allowing the stop clip to rotate freely. The drive component structure of this utility model features high locking stability, providing a more reliable locking force for the umbrella steering knuckle.
