Abstract: The present invention discloses an anti-aging Chinese herb extract, an extraction method and a use thereof. The ginseng-Astragalus membranaceus extract of the present invention comprises 20 to 30% of astragaloside, 1 to 5% of ginsenoside Rg1, 2 to 6% of ginsenoside Re, 0.2 to 0.5% of ginsenoside Rb1. There are 17 characteristic peaks in high-performance liquid chromatography fingerprints of the extract. The extract can effectively improve activity of telomerase, delay cell aging, and can be applied to preparation of an anti-aging product.

Abstract: This invention is relevant to a steady bed cover of pickup truck. The bed cover includes at least two plates. The adjacent plates are connected by rotating shaft structure. This invention provides a steady bed cover of pickup truck with simple structure and great leading function. The connecting strength of rotating shaft structure is enhanced with the cooperation of the ladder-like hook and strip convex. When the bed cover of pickup truck is laid horizontally, the rotating part and the rotating shaft part are subjected to reverse force and are mutually matched, thus enhancing the stability of the bed cover.

Abstract: The invention is relevant to the field of machinery, in particular to a bed cover of vehicle. A fully embedded cover of pick-up truck includes a rail device which is fixed to the inner wall of the hopper of the pickup truck, a front bar, four cover plates, a rear bar and four locks. This invention provides the pickup truck a newly designed fully embedded bed cover which is convenient to use. In this design, the structure of the front bar, the cover plate and the rear bar formed a seal bed cover, so as to prevent rainwater permeating into the cargo hopper. Since the bed cover is built in the cargo hopper, the car body is relatively flat, thus improving the user's use experience.
