The invention belongs to the technical field of cast steel joints, and discloses a movable steel structure special-shaped cast steel joint which comprises a first supporting pipe, a second supporting pipe and a third supporting pipe are sequentially arranged on the outer side of the middle of the first supporting pipe, and a fourth supporting pipe is arranged between the second supporting pipe and the third supporting pipe; the two ends of the first supporting pipe, the top end of the second supporting pipe, the top end of the third supporting pipe and the top end of the fourth supporting pipe are each provided with a guide limiting assembly. Two sets of connecting lugs are further arranged on the outer side of the middle of the first supporting pipe, and one end of each connecting lug is movably connected with a connecting pipe. By arranging the guiding and limiting assemblies, the connecting lugs and the connecting lugs, the guiding and limiting effects can be achieved in the connecting process with a steel pipe, connection with an inclined pipe can be achieved conveniently, meanwhile, the inclined pipe can achieve the small-range swinging effect, and then a certain anti-seismic effect can be achieved; and the connection requirement between the steel pipes is better met.

The utility model belongs to the field of automobile seat headrests, and provides a quick connecting and inserting structure assembly of an automobile seat headrest, which comprises a seat connector connected to a guide sleeve, a guide part and at least two symmetrically arranged mounting parts are formed in the middle of the seat connector, the guide part is positioned at the top end of the mounting parts, and the guide sleeve is positioned at the top end of the mounting parts. The guiding part is used for guiding the headrest supporting rod to extend into the seat connector and movably sleeves the mounting part; and a first conductive piece is integrally injection-molded in each mounting part. Compared with the prior art, the headrest with the wire harness has the advantages that the abutting part movably abutting against the first conductive part is formed on the second conductive part, so that when the headrest with the wire harness is adjusted up and down in the guide sleeve, electric connection between the second conductive part and the first conductive part can be kept all the time by means of the abutting part; therefore, electronic devices in the headrest can be normally played and used when the headrest is adjusted, meanwhile, convenience is provided for quick disassembly and assembly of the headrest, and it is effectively guaranteed that the use experience of customers is not affected.

The utility model relates to the technical field of catalytic furnaces, and discloses a catalytic furnace for catalytic combustion, which solves the problem that waste gas is inconvenient to fully contact with a catalytic plate to influence the catalytic effect, and comprises a main furnace body, a gas inlet pipe is fixedly connected to one side of the main furnace body, and a gas outlet pipe is fixedly connected to the upper surface of the main furnace body. A catalysis assembly and a supporting assembly B are arranged in the main furnace body, after gas is heated and introduced into the catalysis assembly, the gas flows through the inner wall of the main furnace body and one side of a catalysis plate and is catalyzed under the action of the catalysis plate, and the gas rising to the upper portion passes through the interior of a top groove and a partition plate B to achieve the guiding effect; the gas flowing out of the top tank flows downwards under the guiding action of the partition plate A, and finally the gas flows out, so that the contact area with a catalytic plate is fully increased, and the aim of fully contacting with waste gas for catalytic reaction is finally fulfilled.

This application relates to the field of lawnmower technology, and in particular to a high-efficiency heat-dissipating lawnmower drive mechanism and a lawnmower. The high-efficiency heat-dissipating lawnmower drive mechanism includes a first mounting box, a transmission assembly, a stator, a rotor, a second mounting box, a circuit board, and an airflow generating assembly. Compared to existing high-efficiency heat-dissipating lawnmower drive mechanisms, mounting the stator, rotor, and circuit board on the same side of the first mounting box, with relatively close proximity, facilitates coordinated heat dissipation. The airflow generating assembly drives the airflow around the rotor, rapidly expelling hot air from the stator through heat dissipation holes, ensuring effective heat dissipation for both the stator and rotor. The airflow generating assembly also drives the airflow around multiple heat dissipation fins, rapidly cooling the heat dissipation fins and consequently rapidly cooling the circuit board, ensuring effective heat dissipation for the circuit board.

The utility model relates to hinge technical field, and disclose a kind of hinge and door and window for improving sealing, including first mount and second mount for fixed installation, first mount side is equipped with several first axle seat, and several first axle seat are rotatably connected with first rotating piece between, and first rotating piece side is rotatably connected with second rotating piece, and second rotating piece side is rotatably connected with connecting shaft, and second mount is fixedly connected with connecting shaft.The utility model in the middle part position of when opening and closing piece is completely closed in fixed frame body, since opening and closing piece is equipped with the hinge, it plays to prevent the position between fixed frame body and opening and closing piece from appearing deformation condition, improve the sealing effect after fixed frame body and opening and closing piece close, simultaneously, through the hinge can share the load-bearing performance of two guide hinges of fixed frame body and opening and closing piece upper and lower position, improve the stability after fixed frame body and opening and closing piece installation.
