The invention discloses an axle wheel edge assembly and half shaft shell assembly guiding structure and an assembly method thereof. The assembly guiding structure comprises a guiding device, a wheel edge assembly and a half shaft shell assembly. A guide sleeve of the guide device penetrates into a center hole of the wheel edge combining piece, and a transmission shaft of a universal transmission shaft assembly in the half shaft shell combining piece penetrates into the guide sleeve of the guide device. The guide device comprises a guide sleeve, the guide sleeve is a stepped metal pipe fitting with the same inner diameter and different outer diameters, and the inner surface and the outer surface of the guide sleeve are machined. The guide sleeve is adopted to replace the method that in the prior art, an axle wheel edge combination piece is directly and mechanically pressed into a universal transmission shaft of a half shaft shell combination piece to be assembled, the phenomena that the surfaces of shafts are scratched and a drive fork shaft oil seal of the wheel edge combination piece is cut in the assembling process in the past are eradicated, and it is guaranteed that the shafts are intact in the installing process; and the problem of poor sealing caused by early damage of the conventional oil seal is effectively solved. And meanwhile, the device can also be popularized and applied to installation of other mechanical products with similar structures.

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.

The utility model discloses a wrinkle-removing beauty instrument with falling protection, which relates to the technical field of wrinkle-removing beauty instruments and comprises a handle, a cabin and a connecting plate, the cabin is welded at the bottom end of the handle, the connecting plate is welded at the bottom end of the cabin, and a sliding groove is arranged in the handle. The connecting rope is arranged on the wrist of a user in a sleeving mode, an operator grasps the outer side of the handle to use the wrinkle-removing beauty instrument, meanwhile, the position and the direction of the connecting rope can be adjusted through the sliding groove and the sliding rod, the operator can conveniently replace the using face of the wrinkle-removing beauty instrument, and the user can conveniently use the wrinkle-removing beauty instrument through the sliding groove, the sliding rod and the connecting rope. According to the anti-wrinkle cosmetic instrument, the anti-wrinkle cosmetic instrument is not prone to falling off in the using process, the anti-wrinkle cosmetic instrument can be protected and prevented from being damaged due to falling off, it is ensured that the anti-wrinkle cosmetic instrument is kept intact in the using process, and therefore the service life of the anti-wrinkle cosmetic instrument is prolonged.

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.
