3results about How to "Make sure it's intact" patented technology

The utility model relates to the technical field of carbonization furnace feeding, and discloses a carbonization furnace push rod sealing device which comprises a push rod sealing sleeve, two floating assemblies are arranged at the right end of the push rod sealing sleeve, and the floating assemblies are used for guaranteeing that sealing materials are intact. According to the carbonization furnace push rod sealing device, the floating assembly is installed, a floating flange and a floating sleeve on the inner side can be limited through a flange limiting disc and a combined disc, and a certain movable gap exists between the floating flange and the floating sleeve on the inner side of the flange limiting disc and the inner side of the combined disc; by means of the mode, original fixed cylinder body sealing is changed into floating cylinder body sealing, sealing materials are changed into piston ring and fluororubber sealing ring composite sealing from original packing, the service life of the sealing materials is prolonged through engine oil lubrication, and therefore when the push rod of the cylinder body is in a deformation state or generates flexibility, the sealing performance of the cylinder body is improved. And the sealing material can be ensured to be intact so as to achieve a thorough sealing effect.

This invention relates to the field of cable protection conduit technology, specifically a flame-retardant and impact-resistant protective conduit for communication and power cables. The conduit includes a flame-retardant structure comprising an outer tube layer, the inner wall of which is fitted with a heat-resistant outer tube. An impact-resistant protective structure is provided on the inner wall of the inner mounting layer, including a cable mounting bracket outer tube located on the inner wall of the inner mounting layer. One end of the outer tube layer has a conduit interface structure. This flame-retardant and impact-resistant protective conduit for communication and power cables exhibits significant flame-retardant effects, effectively preventing flame spread, avoiding pipe combustion and dripping, and effectively absorbing impacts from external collisions and compression. It can withstand various external impacts such as outdoor construction, vehicle collisions, and heavy object compression. Furthermore, it improves splicing and connection efficiency, is suitable for large-scale cable laying projects, and can significantly shorten the construction cycle.

The utility model relates to anti -fake label technical field especially relates to laser holographic dynamic angle anti -fake label structure, including having first anti -fake label and two -dimensional code scanning area, is equipped with two -dimensional code scanning area on first anti -fake label, still including connecting plate and tear -off plate, first anti -fake label is fixedly connected with connecting plate, is equipped with tear -off plate on connecting plate, both groups of tooth grooves are equipped on connecting plate and tear -off plate. Two -dimensional code scanning area is shielded through tear -off plate, can avoid damaging due to friction or scraping when transporting, guarantees two -dimensional code to keep intact, ensures the anti -fake function.
