The utility model discloses an anti-collision zipper carton, and particularly relates to the technical field of cartons, which comprises a carton body component, a zipper and a zipper, a plurality of reinforcing plates are fixedly connected to a crack of the inner wall of the placement cavity from top to bottom, and slots are formed among the reinforcing plates along a preset axis; detachable reinforcing rods are connected between the multiple inserting grooves, a detachable foam plate is placed at the bottom end of the interior of the containing cavity, and the box body component comprises a box body. The reinforcing plates and the reinforcing rods are arranged, the reinforcing rods are inserted among the reinforcing plates through matching of the inserting grooves in the reinforcing plates, then the strength of the box body is improved through the reinforcing plates and the reinforcing rods, after the box body is collided, the pressure resistance of the box body is improved through the reinforcing plates and the reinforcing rods, and then the box body is effectively reinforced; and the packaging box is prevented from collapsing easily after being extruded in the transportation process, and the guarantee for objects is improved.

The utility model discloses a vibro-replacement gravel pile funnel type pile casing device which comprises a pile casing body which is of a hollow structure with an upper opening and a lower opening. The section of the pile casing body is rectangular, and the area of the section of the pile casing body is gradually reduced from top to bottom to form an inverted-cone-shaped structure. A guide groove is formed in the inner wall of the pile casing body, and the guide groove is matched with a guide rod of a vibrator for limiting; the device solves the problem that in the prior art, an orifice is prone to collapsing during construction of the vibro-replacement stone column, and has the advantages that the orifice can be effectively supported, and collapse is avoided.

The utility model discloses a self -adhesive of can improve the adhesion fastening, including self -adhesive body, the self -adhesive body includes base material layer, the bottom of base material layer is provided with first viscose layer, the bottom of first viscose layer is provided with release paper, be provided with wrinkle prevention subassembly on base material layer, the utility model discloses a wrinkle prevention subassembly can be to the whole of self -adhesive body carries out multidirectional support, makes self -adhesive body when pasting can keep certain tight state, greatly improved the wrinkle prevention effect of self -adhesive body, avoid self -adhesive body when pasting easily because of wrinkle and reduce the adhesion fastening of self -adhesive body, thereby improved the use effect of self -adhesive body, and can after self -adhesive body pastes in the position with certain camber, take down wrinkle prevention subassembly fast, avoid having certain elasticity wrinkle prevention subassembly influence the pasting firmness of self -adhesive body.

The application discloses a kind of three-dimensional mesoporous carbon composite silicon-carbon negative electrode materials and preparation method and application thereof, and relates to the technical field of battery.A kind of preparation method of three-dimensional mesoporous carbon composite silicon-carbon negative electrode material, comprising the following steps: additive 1 and additive 2 are dissolved in deionized water respectively, obtain solution A and solution B, in solution A is added to solution B, obtain solution C;Additive 3 is dissolved in deionized water, obtain solution D, solution C is added to solution D, obtain solution E;High-temperature calcination obtains template A;After reaction, solution G is obtained;Template B is obtained;Sample is obtained;Carbonized sample is obtained, after drying, dry sample is obtained;Dry sample is activated at high temperature in carbon dioxide gas environment, obtain three-dimensional mesoporous carbon material, then carry out chemical vapor deposition, obtain three-dimensional mesoporous carbon composite silicon-carbon negative electrode material.The application solves the problem that significant volume expansion occurs in the charge and discharge process of silicon-based negative electrode material.
