This utility model relates to the field of high-efficiency dispensing equipment technology, and in particular to a glue cartridge replacement mechanism and replacement kit. The key technical points include: a base; a dispensing valve fixedly connected to the base, the dispensing valve having a plug-in module with a glue outlet channel, the plug-in module being used to plug into the bottom end of the glue cartridge, and when the glue cartridge is plugged into the plug-in module, the glue outlet channel connecting with the glue outlet at the bottom end of the glue cartridge; and a glue pressure assembly, which is vertically and vertically mounted on the base and located above the dispensing valve, the glue pressure assembly having an air inlet channel, and the glue pressure assembly being movably connected to the top end of the glue cartridge to connect or disconnect the air inlet of the glue cartridge. This application can significantly improve the glue cartridge replacement efficiency.

This application relates to the field of new energy vehicle charging equipment technology, and discloses a multifunctional mobile vehicle-mounted charging device, including a carrier vehicle. A battery pack and charging module are installed inside the vehicle's cargo compartment. A slide rail is fixedly connected to the top of the cargo compartment, and a support frame is slidably connected to the slide rail. An air extraction component is fixedly connected inside the support frame to extract air from inside the cargo compartment to the outside, thereby accelerating the ventilation efficiency between the inside and outside of the cargo compartment. The bottom end of the support frame facing the rear door of the cargo compartment is connected to the rear door of the cargo compartment via a connecting rod, and the top end is hinged to one end of a drive arm. By directly transmitting the opening action of the rear door of the cargo compartment to the support frame via the connecting rod, the support frame and the air extraction component are driven to slide out of the cargo compartment along the slide rail. This transforms the necessary action of opening the door into the driving force for the deployment of the cooling system and wiring components. The device is ready without additional operating steps, and the linkage process is stable and reliable.

The application is suitable for the technical field of converter control, and provides a network type converter transient and steady state promotion control method based on current latch inhibition, equipment and medium, the method comprises the following steps: in the whole process of power grid fault current limiting and fault recovery, the internal voltage source active power of the network type converter is used as a closed loop feedback quantity to carry out power synchronous closed loop regulation, continuously output angular frequency and voltage reference instruction, and continuously adjust virtual power angle; when it is detected that the power grid fault is cleared, the current real-time virtual power angle is latched as the initial virtual power angle of fault recovery, and the current voltage reference instruction is combined to continuously update the current reference instruction; the virtual power angle, the internal voltage source active power, the current reference amplitude and the grid-connected point voltage are monitored in real time, and when all state variables converge to the steady state interval corresponding to normal operation, the network type converter is automatically controlled to exit current limiting, the current latch problem is effectively solved, and the transient and steady state operation performance of the network type converter is improved.

The utility model relates to the technical field of mechanical devices, and discloses a drop test machine which comprises a bottom plate and a vertical frame fixedly connected to the outer wall of the top of the bottom plate, a fixing rod is fixedly connected to the outer walls of the bottom plate and the vertical frame, a lifting block is slidably connected to the outer wall of the fixing rod, and a frame is fixedly connected to the outer wall of the lifting block. A bearing plate is rotationally connected to the outer wall of the frame through a rotating shaft, a lifting mechanism is installed on the outer walls of the bottom plate and the vertical frame and comprises a first screw rotationally connected between the bottom plate and the vertical frame, a lifting block is in threaded connection to the outer wall of the first screw, and a first motor is fixedly installed on the outer wall of the top of the vertical frame; according to the automatic bag lifting device, through the arranged lifting mechanism, the lifting block can be automatically driven to drive the bearing plate to ascend and descend, mechanical operation is adopted, and the labor intensity of manual bag lifting is reduced.

The utility model discloses a waist support assembly and a seat. The waist support assembly comprises a mounting seat, a main waist support, an auxiliary waist support and a connecting rod mechanism, the main waist support is movably matched with the mounting seat, an elastic element is arranged between the mounting seat and the main waist support, and the elastic element is used for applying forward elastic stress to the main waist support; the auxiliary waist support is arranged on the side edge of the main waist support and pivoted to the installation base so that the auxiliary waist support can rotate around a first axis extending in the vertical direction relative to the installation base. The connecting rod mechanism is installed between the main waist support and the auxiliary waist support and used for driving the auxiliary waist support to swing inwards around the first axis when the main waist support moves backwards relative to the installation base and driving the auxiliary waist support to swing outwards around the first axis when the main waist support moves forwards relative to the installation base. According to the waist support assembly, the waist of a user can be automatically wrapped and loosened, the auxiliary waist support does not need to be manually adjusted, and the use convenience of the waist support assembly is improved.
