The utility model discloses an integrated prefabricated anti-collision wall formwork. The integrated prefabricated anti-collision wall formwork comprises an anti-collision wall formwork body and a quick locking mechanism arranged at the top of the anti-collision wall formwork body. The anti-collision wall template body comprises a rear template, a front template, a first side template and a second side template; through the cooperation between the anti-collision wall formwork body and the multiple sets of quick locking mechanisms, the quick locking mechanisms do not need complex installation tools and tedious operation procedures, fastening connection of the formwork can be quickly achieved through simple clamping and screwing actions, the assembling time is greatly shortened, and the assembling efficiency is improved. The construction efficiency is remarkably improved, the stability and reliability of connection can be effectively guaranteed, it is guaranteed that the formwork is not prone to displacement and loosening in the prefabricating process of the anti-collision wall, and therefore the forming quality of the prefabricated anti-collision wall is improved, the defective rate and the rework phenomenon caused by the formwork problem are reduced, and meanwhile the safety risk in the construction process is reduced.

This application discloses a pair of pliers that is easy to assemble and disassemble, including a left and a right pair of pliers arranged in a cross configuration. The left pliers have a left plier shaft portion, and the right pliers have a right plier shaft portion. The left plier shaft portion includes a left connecting seat with a connecting groove. A connecting sleeve with internal threads is concentrically arranged in the connecting groove. The right plier shaft portion includes a right connecting seat with a gasket mounting groove and a connecting sleeve on opposite sides. A connecting hole is formed at the bottom of the gasket mounting groove. During assembly, the connecting sleeve is inserted into the annular mounting groove outside the connecting sleeve, and the bolt passes through the gasket and the connecting hole and is screwed into the internal thread of the connecting sleeve. Therefore, the pliers provided by this application can be assembled and disassembled using only a screwdriver. Its double-sleeve structure allows for both sliding rotation and adjustment of tightness at any time by tightening the bolt. The two pliers can be separated by removing the bolt, making it convenient to clean the dirt inside the pliers. The assembly and maintenance are simple, and the gasket forms an end face seal to prevent lubricating oil from seeping out, thus avoiding dirty hands and clothes.

This invention discloses a bipolar horizontal battery for preventing liquid and gas leakage, comprising a casing and multiple electrode groups disposed within the casing. Each electrode group includes cross-stacked electrode plates and separators. The electrode plates have a crisscrossing mesh structure. The electrode groups are connected in series via an electrode connection assembly, and a separator is disposed between any two adjacent electrode groups. The electrode connection assembly includes a conductive plate, a conductive insert, and a slot disposed on the side wall of the separator. One end of the conductive plate is connected to an electrode plate, and the other end is connected to the conductive insert. The conductive insert is inserted into the slot, and a wire connected to the conductive insert is disposed within the slot. An electrode group fixing groove and a separator fixing groove are disposed at the bottom of the inner cavity of the casing, and a terminal block is disposed at the end of the inner cavity of the casing. The beneficial effects of this invention are: achieving a stable connection between the electrode groups and the casing while isolating the electro-hydraulic components within the electrode groups, effectively providing a good barrier effect.
