3results about How to "Guaranteed reinforcement effect" patented technology

The present disclosure relates to the technical field of geotechnical engineering. An embodiment of the present disclosure provides a geotechnical engineering drilling device, including a base platform. A support is fixedly installed on the top of the base platform. A moving plate is movably installed inside the support. A first motor is fixedly installed on the top of the moving plate. A drill pipe is rotatably installed at the bottom of the moving plate. In the present utility model, through the rotation of the rotating plate, the reinforcement pile is drilled into the soil. Then, through the rotation of the rotating rod, the casing is displaced downward. The downward displacement of the casing will squeeze the reinforcement block into the soil through the slope surface of the reinforcement block, completing secondary reinforcement. Compared with traditional devices, this device can fix the base platform through the reinforcement pile and can also increase the contact area between the reinforcement pile and the soil through four groups of reinforcement blocks. Through the above technical solution, the technical problems of poor fixing effect and easy deviation of the drill pipe in the prior art are solved.

The application relates to the technical field of batteries and discloses a battery cell and a battery pack. The battery cell comprises a shell, an open end of the shell, a pole group arranged in the shell, the pole group comprising a positive pole sheet, a diaphragm and a negative pole sheet arranged in layers, the diaphragm extending out of the upper side walls of the positive pole sheet and the negative pole sheet, a battery cell cover plate assembly comprising a cover plate and a lower plastic, the cover plate being arranged on the open end, the lower plastic being arranged on the lower surface of the cover plate and in the shell, the lower surface of the lower plastic being provided with a separation part and a pair of limiting parts, the pair of limiting parts being respectively arranged at opposite ends of the lower surface of the lower plastic, the separation part being arranged between the pair of limiting parts, the end area of the separation part away from the cover plate being smaller than the end area of the limiting part away from the cover plate, the length of the separation part being smaller than the length of the limiting part, and the separation part and the limiting part both abutting against the part of the diaphragm extending out of the positive pole sheet and the negative pole sheet. The compression amount of the separation part on the diaphragm is reduced, and the possibility of damage of the separation part to the pole group is reduced.

This utility model relates to the field of home appliance technology, and discloses a housing assembly and a home appliance. The housing assembly includes a first housing, a second housing, and a retaining ring. The second housing is connected to the first housing. The retaining ring is disposed at the connection between the first housing and the second housing, with one end of the retaining ring being engaged with the first housing and the other end being engaged with the second housing. It is used to provide a tension force at the connection between the first housing and the second housing. This utility model continuously applies a tension force that brings the first housing and the second housing closer to each other, effectively eliminating the gap that may be caused by manufacturing tolerances or assembly loosening of the first housing and the second housing, making the first housing and the second housing more tightly joined at the connection, improving stability and aesthetics.
