This utility model relates to the field of microwave technology and discloses a microwave transmitter module, including a metal housing, an internal base plate, an L-shaped plate on the base plate, fixing bolts on the L-shaped plate, and several positioning holes on the upper side of the base plate. A transmitting assembly is mounted on the base plate, an antenna is mounted on the right side of the metal housing, and a mounting assembly is located on the front side of the metal housing. An inner shielding layer is installed inside the metal housing, and an outer shielding layer is located inside the inner shielding layer. Heat dissipation fins are mounted on the upper side of the metal housing. In this utility model, by adjusting the position of the L-shaped plate, microwave oscillators of different lengths can be quickly and accurately installed and fixed, meeting diverse usage needs. Furthermore, the disassembly process is clear during microwave oscillator maintenance, greatly improving maintenance efficiency.

This utility model discloses an acrylic resin liquid filling device, relating to the field of acrylic resin liquid filling. It includes a placement box, a delivery pipe, a delivery pump, a container, an air blowing mechanism, and an air supply mechanism. The delivery pipe is fixedly connected to the upper left end of the placement box, and the delivery pump is fixedly connected to the delivery port of the delivery pipe. A container is fixedly connected to the bottom left end of the delivery pipe, and an air blowing mechanism is provided on the left side of the container. An air supply mechanism is fixedly connected to the top of the placement box. The air blowing mechanism uses two sets of nozzles to deliver external hot air to the outer wall of the delivery pipe, maintaining a suitable working temperature for the acrylic resin liquid and preventing the acrylic resin liquid from experiencing a decrease in flow rate due to low temperature, incomplete filling, or equipment overload. The air supply mechanism delivers nitrogen gas into the placement box, replacing the air at the top of the box to create an oxygen-free environment, preventing the acrylic resin liquid from increasing in viscosity and turning yellow.

The utility model relates to the technical field of lithium batteries, and discloses a waterproof corrosion-resistant lithium battery which comprises a first protective shell, an upper connecting plate, a lithium battery, a lower connecting plate and a second protective shell, the lithium battery is arranged between the upper connecting plate and the lower connecting plate, and the upper connecting plate is installed at the top end in the first protective shell through bolts. The first protective shell and the second protective shell are fixed through a connecting ring and a bolt, the connecting position is good in sealing performance, sealant is arranged between the isolation plate and the heat dissipation plate, the vent hole and related gap design can block moisture and prevent the moisture from making contact with battery components, and the heat dissipation plate is installed in an installation hole of the isolation plate. The upper cooling fin and the lower cooling fin increase the heat dissipation area and can effectively dissipate heat generated by working of the lithium battery, the power port is formed in the right end of the first protective shell and connected with the upper connecting plate, charging and discharging of the lithium battery and external equipment and accurate inserting connection of the positioning groove and the positioning block are achieved, it is ensured that the installation positions of components are accurate, and it is ensured that the overall structure of the battery is stable.

The utility model discloses a high -efficient heat dissipation's nine hole COB integrated plant lamp shell, including protection bottom plate, fixed frame and top cap, the position department of top cap inboard corresponds LED lamp pearl and all is provided with inner cover body, and the outer side of inner cover body all is provided with outer cover body, the airflow channel is formed between outer cover body and inner cover body, and the both ends of airflow channel all are provided with air port, the both ends of fixed frame all are provided with ventilation, and the position department of two ventilation inboard corresponds air port and installs respectively outgoing fan and air inlet fan. The utility model discloses the airflow channel formed between the inner cover body and outer cover body of top cap inboard setting and the air port design of airflow channel both ends, ensure that the air flow is smooth, and further improve the heat dissipation effect. The ventilation of fixed frame both ends setting, cooperate the use of outgoing fan and air inlet fan, form effective forced convection heat dissipation system, make internal heat can discharge rapidly, keep LED lamp pearl in suitable working temperature.
