This utility model relates to the field of modular sofa technology, and discloses a modular sofa that can be used for both sitting and sleeping, which can be freely combined. It includes a sofa base, with a fixed plate slidably connected between the two sides of the inner wall of the sofa base. Four telescopic rods and two hollow sleeves are fixedly connected to the top of the fixed plate. An extension plate is fixedly connected to the top of the four telescopic rods, and a drive frame is fixedly connected to one side of the two hollow sleeves. A drive assembly is provided on the inner wall of the drive frame. This utility model, through the combined use of the telescopic rods, hollow sleeves, extension plate, and drive assembly, enables expansion via the extension plate and worm gear mechanism. Users can easily pull out the extension plate and use the worm gear to drive the lead screw to raise and lower, keeping the extension plate aligned with the plane of the sofa base. This effectively increases the length of the sofa, providing more resting space, and is especially suitable for users who need a larger resting area.

The utility model discloses a portable Internet of Things gateway, which comprises a host, a plurality of networking interfaces arranged inside the front end of the host, an on-off key arranged on the right side of the plurality of networking interfaces, a power interface arranged on the right side of the on-off key, and a signal enhancement rod arranged at the left front corner of the upper end of the host. According to the utility model, a detachable signal enhancement rod structure is adopted, the signal enhancement rod can be combined into a whole or split into two independent units to be arranged according to the environment, and the signal enhancement rod can be flexibly split and combined according to the requirements; the gateway arrangement flexibility is improved, and the communication quality is ensured. The reinforcing rod can rotate to adjust the direction and can be completely accommodated in the host groove body, so that the device can be rapidly deployed to the optimal signal position, the portable transportation requirement can be met, and the environmental adaptability and the network distribution efficiency of the device are improved.

The utility model discloses a kind of hand tools for gear box body assembly, related to assembly tool technical field, solve when actual operation, often need to frequently switch between different tools, seriously affect assembly efficiency, also easily cause the problem of loss due to tool messy stacking.A kind of hand tools for gear box body assembly, comprising: left handle;The left handle adopts cylindrical structure, and the side of left handle is equipped with screw hole structure;The right handle of cylindrical structure is installed and arranged on the side of left handle by screw thread cooperation;The outside end of left handle and right handle is fixedly set with the mounting plate of a group of mountain-shaped plate structure, and the outside end of mounting plate is equipped with the circular through slot structure of through type;The upper and lower sides of the inside one end of two groups of mounting plate are rotatably set with the connecting block of a group of round plate structure;Greatly reduce the time of tool taking and replacing, significantly improve the continuity and efficiency of assembly operation.

The invention discloses an assembling method for prefabricated well pieces of a rectangular assembly type open caisson. The rectangular assembly type open caisson comprises a plurality of annular well sections which are sequentially connected end to end in the length direction. Each circumferential well section comprises more than two prefabricated well pieces to form four splicing structures; the splicing process comprises the following steps that firstly, all the prefabricated well pieces are spliced into corresponding circumferential well sections; 2, blade foot ring well sections are assembled; and 3, the blade foot ring well sections are sunk, all the circumferential well sections are spliced on the blade foot ring well sections one by one, and sinking at the corresponding height is carried out after splicing of one circumferential well section is completed till sinking of all the circumferential well sections of the rectangular assembly type open caisson is completed. By means of the method, the rectangular assembly type open caisson can be flexibly disassembled, well piece lightweight transportation, positioning, reliable connection and efficient splicing are achieved, and the structural integrity and the construction quality of the open caisson are improved.

The utility model discloses a sample collecting device for soil remediation, which relates to the technical field of soil remediation and comprises a support plate and a device frame, an adjusting push rod is vertically mounted in the middle of the support plate in a threaded manner, support rods are vertically mounted at four opposite angles of the bottom of the support plate in a threaded manner, and two groups of support frames are slidably connected to the surfaces of the middle sections of the support rods. The device frame is connected to the bottom end of the adjusting push rod. According to the sample sampling device for soil remediation, a supporting plate, an adjusting push rod, a supporting rod, a supporting frame, a device frame and a sampling insertion plate are arranged in a modular structure, so that the supporting plate, the adjusting push rod, the supporting rod, the supporting frame, the device frame and the sampling insertion plate have good structural disassembly and assembly performance, the flexibility of the overall structure of the device can be guaranteed, and the device can be conveniently disassembled for transportation and carrying; in addition, a supporting frame is connected to the surface of a supporting rod, so that the structural stability of the whole device inserted into a soil layer can be guaranteed, and a sampling insertion plate around a device frame at the lower end can be driven by rotating an adjusting push rod to rotate into the soil layer for stable sampling.
