4results about How to "Not easy to pull out" patented technology

The utility model relates to a bottle cap assembly and a container, the bottle cap assembly comprises an inner plug piece, an inner cap piece, an inner sleeve piece and an outer piece, the inner plug piece is arranged on a first liquid flow opening of the inner sleeve piece, the inner cap piece is plugged on a second liquid flow opening of the inner sleeve piece, the inner sleeve piece comprises a first inner sleeve and a second inner sleeve which are made of different materials, and the outer piece is arranged in the first inner sleeve; the second inner sleeve is arranged on the peripheral face of the first inner sleeve in a surrounding mode, and the outer part is arranged on the inner cover part and the second inner sleeve in a sleeving mode and attached to the peripheral face of the second inner sleeve. According to the bottle cap assembly and the container, the first inner sleeve and the second inner sleeve are made of different materials, so that the first inner sleeve connected with the inner plug piece and the inner cap piece can be made of materials which do not affect contact with liquid, and the safety requirement is met; and the second inner sleeve connected with the outer part can be made of a material which is excellent in temperature resistance and impact resistance and is prohibited from being in contact with liquid, so that the inner sleeve part is not easy to pull out, and the bottle body or the outer part can be damaged when the inner sleeve part is forcibly pulled out, and the aim of preventing counterfeiting is fulfilled.

The utility model discloses a power supply module with a protection structure, which comprises a power supply module, a joint is fixedly arranged at the front part of the lower inner wall of the power supply module, an installation cover is fixedly arranged at the upper end of the power supply module in a penetrating manner, a plurality of first through holes are formed in the upper part of the front end of the installation cover, and a second through hole is formed in the rear part of the upper end of the installation cover. A heat dissipation device is fixedly installed on the rear portion of the left end of the power module, and a heat conduction device is fixedly installed in the middle of the left end of the power module. According to the utility model, through the installation plate and the installation groove on the installation plate, an external connection wire can be guided, and after the external connection wire passes through the installation groove and is in butt joint with the wiring terminal, the external connection wire can be effectively limited and clamped through the anti-skid sleeve arranged in the installation groove and the plurality of anti-skid salient points on the inner wall of the installation groove, so that the external connection wire is prevented from being damaged. And the upper end of the mounting groove is also provided with a silica gel ring, so that the abrasion of the connection part of the external wiring and the mounting groove can be effectively reduced.

This utility model discloses a magnet assembly structure for a pod-type electronic cigarette, comprising a cartridge and a main unit. The cartridge has a first groove at its bottom, into which a first magnet is embedded. A second groove is located at the bottom of the insertion cavity, into which a second magnet is embedded. The first and second magnets are magnetically attracted to each other. The first and second grooves have identical structures. The sidewall of the first groove has multiple raised ribs perpendicular to its bottom. One end of each rib near the groove opening is beveled, serving as a guide for the insertion of the first magnet. The first magnet is interference-fitted to the raised ribs. A gap is formed between the sidewall of the first magnet and the sidewall of the first groove, filled with glue, thus firmly bonding the first magnet to the first groove. Both the first and second grooves have protrusions at their bottoms, forming glue reservoirs, ensuring glue adhesion around the magnet and ensuring a secure and reliable magnet assembly.

This invention relates to the field of road engineering materials and solid waste resource utilization technology, specifically to basalt fiber reinforced coal gangue asphalt mixture, its preparation method, and its application. By weight, it comprises 100 parts activated coal gangue aggregate, 4-7 parts asphalt binder, 0.2-0.5 parts basalt fiber, 1-3 parts hydrated lime, and 0.3-1.5 parts silane coupling component. The coal gangue is calcined at 550-850°C to remove hydroxyl groups, transforming its surface into a slightly alkaline amorphous silica-alumina active surface. Utilizing the silica-alumina homology between the coal gangue and basalt fiber, the aggregate and fiber are covalently bonded at the contact interface via Si-O-Si and Si-O-Al bonds to form a continuously stressed aggregate-fiber-asphalt interface network. The hydrated lime provides anti-stripping, alkaline activation, and calcium node properties, achieving solid waste resource utilization while maintaining a freeze-thaw splitting strength ratio of over 90% and a dynamic stability of over 6000 cycles / mm.
