This utility model discloses an easy-to-install reinforced concrete drainage pipe, including a first pipe and a second pipe disposed to the side of the first pipe. A sealing snap-fit ​​first is fixedly connected to the outer contour of the first pipe near the second pipe. A sealing snap-fit ​​second, detachably connected to the sealing snap-fit ​​first, is fixedly connected to the outer contour of the second pipe near the first pipe. A connecting pipe is snapped onto the opposite sides of the first and second pipes. Fixing bolts are provided at the four corners of the sealing snap-fit ​​second and are bolted to the sealing snap-fit ​​first. This utility model, through the design of the sealing snap-fit ​​first, sealing snap-fit ​​second, and connecting pipe, allows workers to quickly assemble and install the two pipes. After installation, it effectively seals the connection between the two pipes, increasing the sealing effect.

This utility model relates to the field of building engineering technology, specifically a fireproof and heat-insulating curtain wall for building engineering, including a curtain wall body, a sealing plate, and a support plate. Each curtain wall body has a fixing plate at its top, and long bolts pass through pre-drilled openings at the top of the fixing plates. Sealing plates and support plates are respectively provided at the top and bottom between two sets of curtain wall bodies. A fireproof layer and a reinforcing layer are respectively provided between the two sets of curtain wall bodies. Bolts are installed and tightened at the bottom front side of each curtain wall body through pre-drilled openings. By inserting a concave locking block between two sets of slots, inserting a plug-in post wrapped with an anti-slip plate into the plug-in hole, and then pressing the two ends of the locking block into the slot, the two sets of curtain wall bodies can be quickly spliced ​​and installed, improving installation efficiency and thus practicality. The sealing layer between the two sets of curtain wall bodies can seal the joint gaps, further improving the sealing performance.

The utility model relates to the technical field of foam concrete wallboards, and discloses a fast-assembly type foam concrete wallboard which comprises a foam concrete wallboard body, the right side of the foam concrete wallboard body is fixedly connected with a clamping block, and the section of the clamping block is in an isosceles trapezoid shape. A clamping groove clamped with the clamping block is fixedly connected to the left side of the foam concrete wallboard body, a splicing block with an arc-shaped section is fixedly connected to the top of the foam concrete wallboard body, and a splicing groove is formed in the bottom of the foam concrete wallboard body; the left wall plate and the right wall plate are quickly positioned through embedding of the clamping blocks and the clamping grooves, the transverse splicing structure is locked in cooperation with the limiting rods penetrating through the clamping blocks and the wall plates and the elastic dampers, the upper wall plate and the lower wall plate are vertically and accurately aligned through the splicing blocks and the splicing grooves, and the installation efficiency and the alignment precision of the wall plates are remarkably improved; the method is suitable for high-efficiency construction scenes of fabricated buildings.

The application discloses a mobile phone loudspeaker shell capable of preventing deformation, which comprises a shell body, a limiting hole is formed in the top end of the shell body, a fixed edge is arranged on the upper end of the shell body, a protective layer is connected to the inner side of the shell body, a closing cover is installed above the shell body, fastening bolts are installed on the left and right ends of the closing cover, a pressing mechanism is installed on the lower surface of the closing cover, an extrusion plate is arranged on the right side of the pressing mechanism, a sound hole is formed in the lower left of the shell body, and a bottom plate is bolt-connected to the bottom of the supporting frame. The mobile phone loudspeaker shell capable of preventing deformation can effectively improve the wear resistance and strength of the shell body by the wear-resistant layer made of ceramic material and the reinforcing layer internally provided with braided metal wires, and can prevent the shell body from being deformed in the long-term use.

The utility model provides an energy-saving assembly type building external wall thermal insulation integrated device, which relates to the technical field of assembly type buildings and comprises an external wall panel, a connecting piece I and a connecting piece II, a groove is formed in the rear end of the outer wallboard, three sets of round holes are formed in the left side and the right side of the outer wallboard respectively, a set of threaded bolts are clamped in the three sets of round holes in the left side and the right side of the outer wallboard respectively, a connecting plate is connected into the groove in the rear end of the outer wallboard, the heat preservation board is connected to the rear end of the connecting plate, and the inner wallboard is connected to the rear end of the heat preservation board. The square hole is formed in the connecting plate, and the eight sets of arc-shaped plates are connected into the square hole in the connecting plate, so that the eight sets of arc-shaped plates can form a plurality of air cavities in the square hole, the air cavities can play an extra heat insulation role, the heat preservation effect is improved, meanwhile, the weight of the heat preservation plate is reduced, and the construction difficulty is lowered; the problems that an existing energy-saving assembly type building outer wall heat preservation integrated device is prone to being influenced by the self weight in the construction process, and construction is not convenient are solved.

The utility model relates to dumbbell technical field, and disclose a quick dismounting's modularization dumbbell, including dumbbell piece mechanism, still include: hold the lever mechanism, the dumbbell piece mechanism includes installation box, top cap, through groove, splicing post, splicing groove and fixed orifices, the hold lever mechanism includes hold lever main part, antiskid cover, spacing protruding, installation post, second installation hole, return spring and fixed pin, the utility model discloses through the through groove and splicing groove and make the side of installation box close in the side of antiskid cover and push fixed pin to make fixed pin insert fixed orifices inside to fix top cap when reset spring, and top cap compresses installation box to complete the fixing of dumbbell piece mechanism, realize the splicing installation of dumbbell piece mechanism and hold lever mechanism, when dismounting, through control switch control electromagnet power generation magnetic force to the iron sheet produce suction force to make the connecting rod drive fixed pin and enter second installation hole inside to realize dumbbell dismounting, be favorable to improving work efficiency.
