The utility model discloses an automobile gear handle assembling structure which comprises an upper assembling assembly and a lower assembling assembly. The upper assembling assembly comprises two sets of supporting plates, a mounting frame mounted on the two sets of supporting plates, a sliding rail mounted on the inner side of the mounting frame, a driving motor mounted at the top of the mounting frame, a rotating shaft connected with the output end of the driving motor and a sliding sleeve arranged on the rotating shaft in a sliding mode. By means of the assembling structure, the requirement for manual operation is reduced, the production cost is effectively reduced, a large number of manpower resources need to be invested to conduct screw tightening and other work in a traditional split type assembling mode, the labor intensity of workers is lowered, the labor intensity of workers is lowered, the labor intensity of workers is lowered, and the production efficiency is improved. And the investment in the aspect is greatly reduced through the quick assembly structure, and the waiting time is shortened by efficiently completing tasks, so that the assembly efficiency is improved.

The utility model provides a filter element and a pet water dispenser. The filter element comprises a filter element shell and a filter medium, a plurality of filtering grooves and at least one supporting groove protrude from the water outlet surface of the filter element shell; each filter tank is filled with the filter medium, and the volume of the filter medium filled in each filter tank accounts for 50-80% of the total volume in the filter tank; each supporting groove is completely filled with sponge and is thicker than or equal to the filtering groove; the filter grooves and the supporting grooves are arranged at intervals, and at least one supporting groove is formed in the center of the water outlet surface of the filter element shell. According to the filter element and the pet water dispenser provided by the utility model, the water flow speed and the filtering efficiency of drinking water are improved, the filter element cannot collapse and deform, the sponge in the supporting groove can also play a role in adsorption besides a supporting role, and the filtering effect of the filter element is further improved.

The utility model discloses a production mould of motor shell, including forming mechanism, cooling water adjusting mechanism and adjusting auxiliary mechanism, the forming mechanism includes upper module and bottom module, the cooling water adjusting mechanism includes adjusting pipe and rotating sleeve, the adjusting auxiliary mechanism includes outer tooth ring and damping ring, and the forming mechanism realizes the accurate forming of motor shell through the cooperation of upper module, bottom module, forming block and forming groove, and the design of injection moulding hole through forming block ensures that injection moulding material fills evenly, optimizes injection moulding path, reduces bubble and defect formation, and the combination design of adjusting pipe and rotating sleeve is adopted to cooling water adjusting mechanism, realizes the accurate control to cooling water flow, and the cooperation structure of spin -in block and plugging board can change the flow area of adjusting pipe to adjust the cooling rate, and spin -in block provides constant pressure, ensures that the adjusting system is stable and reliable.

The application provides a damper capable of completely eliminating or effectively reducing the idle stroke of the damper, comprising an inner cylinder, a liquid storage cylinder, a first sealing assembly, a bottom valve assembly and a piston assembly, wherein the piston assembly comprises a piston rod and a piston assembly. When the piston rod is in the maximum stroke state, the liquid level of the working liquid in the inner cylinder and the liquid level of the working liquid in the liquid storage cylinder are flush, and the liquid level of the working liquid in the inner cylinder is at least flush with the lower surface of the piston assembly; when the piston rod is in the maximum stroke state, the volume of the space above the working liquid level in the liquid storage cavity is a first volume, the volume of the space above the working liquid level in the inner cylinder and not occupied by the piston assembly is a second volume, and the part of the piston assembly above the working liquid level is a first part; when the piston assembly is completely pressed into the bottom of the inner cylinder, the volume of the first part below the working liquid level is less than or equal to the sum of the first volume and the second volume.
