The utility model discloses a modularized chair, which relates to the field of furniture structures and comprises a chair back main body, armrest main bodies, chair leg main bodies and a seat cushion plate, the chair back main body, the armrest main body and the chair leg main body are respectively formed by splicing a first chair back module and a second chair back module, splicing a first armrest module and a second armrest module as well as splicing a first chair leg module and a second chair leg module. According to the scheme, the modular structure below the chair can be clearly displayed, the ornamental value of the chair is increased, the first splicing blocks and the second splicing blocks are combined in a mutual lap joint, fitting and meshing mode to form the structure of the chair, the chair comprises a backrest, armrests, chair legs and other components, the module connection mode is achieved through customized hole site design, and the modular structure is more attractive. And the connecting sticks with different sizes are used for stable connection, so that the modules can be easily disassembled and recombined.

A combined floating pipe structure suitable for offshore floating photovoltaic platforms is characterized by comprising a core load-bearing pipe, a buoyancy layer, and ribs; the buoyancy layer is disposed outside the core load-bearing pipe and fixed by ribs that are fixedly connected to the core load-bearing pipe. This invention employs a steel-HDPE combined structure or a steel-airbag combined structure, combining high load-bearing capacity, high stability, and high durability.

The utility model discloses a kind of automobile silica gel pipe water pressure demolding devices, solve the problem of low efficiency, great labor intensity of traditional manual demolding. The device includes fixed frame, connector and detachable forming die, and there is support tube in forming die, support tube is connected water pump by water pipe, support tube is connected shunt pipe, and water tank is equipped on the surface of forming die. Its preferred structure has the support sleeve of forming die large diameter end inside and the threaded connection of connector movable end, water pump input end is connected external water tank through inlet pipe, connector sleeve sealing ring, support tube and forming die coaxial and shunt pipe equidistant arrangement, water tank is shunt groove with strip-shaped opening, and shunt pipe and die inner wall have sealing pad layer. Its beneficial effect is to use water pressure to demould easily, improve efficiency, reduce labor intensity, and connection is stable, sealing performance is good, ensure that device normal operation, meet large-scale production demand, reduce personnel injury risk, improve work efficiency and quality.

This utility model relates to the field of noise reduction equipment technology and provides an engine noise reduction device, comprising: a noise reduction housing with an exhaust port at its rear end and an opening at the other end; a cover plate disposed at the opening of the noise reduction housing, the cover plate having an inner tube inside the noise reduction housing, a push plate inside the inner tube, an exhaust gas inlet on the cover plate, the exhaust gas inlet communicating with the interior of the inner tube, exhaust gas entering the interior of the inner tube and pushing the push plate to slide, and an elastic element between the push plate and the inner tube. Thus, this utility model, by setting a noise reduction structure that can adjust the exhaust state, ensures that the working state of the noise reduction structure is automatically adjusted when the engine's operating conditions change, thereby effectively removing engine noise and reducing exhaust back pressure, achieving real-time adjustment of the engine's exhaust back pressure.

The utility model relates to the technical field of naked eye display, in particular to a transverse cylinder dynamic naked eye panoramic all-digital immersive media display device which comprises an LED display screen module, a rectangular galvanized steel pipe, a fixing piece and a fixing frame which are distributed in a transverse cylinder mode, and the LED display screen module is formed by splicing a plurality of arc-shaped LED screens. The rectangular galvanized steel pipe is arranged in the axial direction of the fixing frame and used for supporting the LED display screen module, a U-shaped clamp is arranged on the rear side of the LED display screen to serve as a fixing piece, the connection stability is enhanced through an inner arm magnet piece, and rapid installation and disassembly are facilitated. The balance weight base with expansion bolts is arranged at the bottom of the fixing frame, it is ensured that the overall structure is stable and safe, the equipment is reasonable in structure, convenient to install, high in visual immersion and suitable for scenes such as virtual reality, digital exhibition halls and game experience, and high-quality naked eye panoramic dynamic image display is achieved.

The invention discloses a flow state filling type adjustable dumbbell and a production method thereof. The adjustable dumbbell comprises a grab handle structure and two balance weight structures arranged at the two ends of the grab handle structure respectively. The counterweight structure comprises a plurality of counterweight units which are detachably connected. And the counterweight unit comprises a counterweight disc. And a closed cavity is arranged in the counterweight disc. And the closed cavity is filled with a flow state filling body. The blow-molded thin-wall containing shell structure is used for bearing low-cost flow state filling bodies such as iron sand, the low-cost balance weight disc is obtained, dumbbell modular design is conducted through the low-cost balance weight disc, the balance weight units based on the flow state filling bodies are detachably stacked in the axial direction, and therefore the balance weight disc is formed. The weight of the dumbbell can be flexibly switched among a plurality of preset gears, the weight can be quickly adjusted on the premise of not depending on a complex mechanical adjusting mechanism, and the use flexibility and adaptability of the dumbbell are remarkably improved.
