This utility model provides an easy-to-install toilet seat mounting component, relating to the technical field of toilet parts. It includes a screw, a locking seat, a locking element, a nut, and a stop block. The locking seat has screw holes at both its top and bottom. A screw is threaded through the surface of the screw hole near the top of the locking seat. The nut is located inside the locking seat, and a mounting groove is provided on one side of the locking seat. The nut is vertically positioned inside the locking seat and horizontally within the mounting groove. The nut is threadedly connected to the screw. A stop block is provided on the other side of the locking seat. The nut can be easily adjusted in direction within the locking seat and connected to the screw via the nut mounting groove, eliminating the need for complex operations and professional tools. The locking element is installed through an open groove and a retaining shaft, simplifying the installation process, reducing difficulty, and improving efficiency. Furthermore, the retaining shaft and nut retainer on the inner wall of the locking seat restrict the movement of the retaining shaft and nut, ensuring the stability of the installed component. The locking element cooperates with the stop block and rotates around the retaining shaft, ensuring a tight and reliable fixation of the toilet seat.

This utility model discloses a double-sealed sterile sealing cap and a burlap sack, including an inner cap, an outer cap, and a sealing assembly between them. A first annular sealing ridge on the edge of the inner cap and a first annular sealing groove on the outer cap are press-fitted to form an inner cavity, and a sealing ring enhances the sealing performance. A second annular sealing ridge is provided on the edge of the outer cap, on which an annular airbag is embedded. Inflated through the air inlet, it forms a radial compression sealing structure, achieving an outer layer seal. The sealing assembly also includes a vacuum valve penetrating the outer cap, allowing vacuum evacuation of the container through the air vents in the inner cap. A locking assembly consisting of a pressing block, an elastic connecting strip, and a latch is provided on the top of the outer cap to further strengthen the seal. This sealing cap, through its double-sealing structure and the synergistic effect of vacuum sealing and airbag sealing, effectively ensures the sterility of the burlap sack, prevents contamination, and improves ease of use and stability, making it suitable for the stringent requirements of sterile packaging in the medical field.

This utility model relates to the technical field of cement product manufacturing equipment, and discloses a high-pressure column forming machine, including a base plate. A connecting column is rotatably connected to the left side of the base plate. Cams are fixedly connected to both ends of the connecting column. A motor is fixedly connected to the outside of the front cam, and a connecting plate is fixedly connected to the outside of the cam. A bearing plate is fixedly connected to the other end of the connecting plate. A limit component is provided on the outside of the bearing plate to limit its movement. Two adjustment components are provided on the right side of the base plate to flexibly adapt to processing requirements. This utility model effectively reduces the hidden dangers of column cracking and insufficient load-bearing capacity caused by concrete quality problems, ensures that the column forming dimensional accuracy meets requirements, and is simple and convenient to operate, reducing the labor intensity of workers and improving production efficiency.

The utility model relates to the technical field of air filters, in particular to an air filter, which comprises a front pressing plate. An adjusting groove is formed inside the front pressing plate, and a positioning groove is also formed inside the front pressing plate. The positioning groove is connected to the adjusting groove through a communication groove. A screw rod is movably connected to the inner wall of the adjusting groove, and an adjusting plate is threadedly connected to the outer wall of the screw rod. Hollow grooves are formed at both ends of the adjusting plate, and linkage columns are fixedly connected to the inner walls of the hollow grooves. A locking plate is arranged inside the communication groove, and a linkage block is fixedly connected to one end of the locking plate located inside the adjusting groove. A linkage groove is formed inside the linkage block, and the linkage column penetrates through the linkage groove. A rear pressing plate is arranged at the rear end of the front pressing plate. A positioning block is fixedly connected to the outer wall of the rear pressing plate, and a locking groove is formed on the outer wall of the positioning block. One end of the locking plate extends into the locking groove, and a filter element is arranged between the front pressing plate and the rear pressing plate. For the utility model, the installation and disassembly of the filter element can be quickly completed without tools, the operation is simple, and at the same time, the stability and sealing performance of the filter element are ensured, and the filtering efficiency is improved.

This utility model provides a fixing support device for vertically laid cables. A triangular support frame is formed by horizontal, vertical, and diagonal braces. The vertical braces are secured with clips at both ends. A guide rail on the top surface cooperates with the guide groove of the cable fixing device, allowing for flexible installation of the cable fixing device on the support surface. The cable fixing device consists of a first clamping rod and a second clamping rod with arc-shaped clamping holes clamping each other and fastened with connecting bolts. A rubber ring inside the arc-shaped clamping hole fits into the groove of the clamping hole. Positioning protrusions between the clamping rods are inserted into positioning holes. Adjacent devices are connected by positioning pins, positioning pin holes, and locking pins, securely clamping the cable. This device has a stable and reliable structure, is easy to install and maintain, effectively prevents cable tangling, evenly distributes pressure, reduces wear, and improves heat dissipation. It is suitable for vertical cable laying in various scenarios, significantly improving cable laying efficiency and quality, and extending cable lifespan.
