The springs are used for supporting the outer long vertical plate and the inner long vertical plate, and flexible collision avoidance of the telegraph pole is achieved through the springs and the outer long vertical plate .

The invention relates to a magnetic core molding die, which includes a machine body and a cooling structure. A lower mold platform is fixed on the top of the upper end of the machine body, and an upper mold platform is arranged on the top of the upper end of the lower mold platform. The top of the upper mold platform is distributed in parallel. There is a material conveying pipeline, side sliding platforms are distributed on both sides of the upper end of the lower mold platform, and guide rails are distributed parallel to the middle part of the lower end of the side sliding platform, the inner wall of the guide rails is slidingly connected with a cooling structure, and the middle part of the lower mold platform The front end is provided with a conveying platform. In the present invention, through the arrangement of the machine body and the lower die table, the machine body and the lower die table are distributed horizontally, and the welded integral structure is formed between the machine body and the lower die table, and the entire machine body and the lower die table are used as the basic fixed structure of the equipment It is connected in the form of welding, which has a stable structure and is not easy to break, and the entire equipment is distributed horizontally, which can effectively ensure that the mold cavity is evenly filled during the pouring process.

The invention discloses a pier column peripheral buffer protection assembly for bridge construction, and relates to the technical field of bridge protection. The invention includes a pier column body; a protective mechanism is movably installed on the side of the pier column body; the protective mechanism includes two anti-collision assemblies with the same structure and connected to each other through connecting pieces; the anti-collision assembly includes an upper hoop, a middle hoop and a lower hoop. Hoop; the limit frame is hinged on the side of the lower hoop; one surface of the limit frame is hinged with two symmetrically arranged first compressive and tensile members and two symmetrically arranged second compressive and tensile members; two first compressive and tensile members are hinged. The ends of the tension parts far away from the limit frame are hinged with the middle hoop; the ends of the two second compression and tensile parts far away from the limit frame are hinged with the upper hoop. Through the design of the protection mechanism and the anti-collision component, the invention adds a buffer protection device on the basis of the traditional bridge pier column, and then effectively improves the anti-collision performance of the bridge pier column through the layout of the buffer protection device.

The invention provides a reversing anti-collision shock reduction device, and relates to a rear anti-collision device of a medium carrier vehicle. A plurality of beams are arranged between two longitudinal girders (5) from front to rear to form a crossbeam of the medium carrier vehicle. A connection plate (21) is fixedly connected with the rear portions of the two longitudinal girders (5). At least two hydraulic cylinders (23) are fixed to the lower portion of the connection plate (21) through a hydraulic cylinder fixing plate (16). Pistons (24) of the at least two hydraulic cylinders (23) are fixedly connected with an anti-collision shock reduction plate (15) on the rear portion to form the reversing anti-collision shock reduction device. According to the reversing anti-collision shock reduction device, the anti-collision shock reduction plate is arranged on the lower portion of the rear end of the crossbeam of the medium carrier vehicle and is protected by the hydraulic cylinders and a spring, the harm, caused by vehicle collision, to the crossbeam can be partially defused, and the situation that a car is plunged in the bottom of a truck and the driver of the car and passengers are dead can be reduced.

The invention discloses a starting mechanism of a mechanical time-telling watch. According to the starting mechanism, a through groove is formed on a spacer ring, and a pull core support is fixed in the through groove of the spacer ring; a connecting sleeve is respectively connected and fixed with one end of a pull core and a square end of a shifting hander as a whole, and the other end of the pull core is a free end; the pull core which is sheathed with a waterproof sealing pipe and a pressure spring penetrates through a connecting block and the pull core support; the pressure spring is arranged in a range of the length of the support; the connecting block is fixedly arranged at a gap formed on the pull core; the pull core penetrates through the connecting block, and the connecting block is fixedly connected with a shafting block; the shafting block in contact with or separated from a movement time-telling starting plate; and upper and lower ends of the exterior of the spacer ring are provided with waterproof rubber rings. The starting mechanism of the invention is advantageous in that: because waterproof rubber rings for sealing are arranged between the spacer ring and a watchcase, and a waterproof sealing pipe is arranged between the spacer ring and the inner pull core, the contact between the exterior and the interior is obstructed from an outermost end, and sealing is carried out from the interior, thereby enabling favorable dustproof and waterproof effects to be achieved. According to the starting mechanism, a sealing box is omitted, which enables a watch with a standard size to be small and thin.

This invention discloses a ceramic glaze improving method, including the following procedures: carry out supermicro refining treatment to ceramic glaze, dry the powder after being refined to get the finished product. The good effect of this invention relies in: refining the glaze can greatly shorten the calcining time and also decrease the using amount of glaze. It saves the energy and lowers the cost. And the ceramic calcined has good performance, and the surface glassiness and water absorption are better than the conventional glaze product.

The invention belongs to the technical field of steel wire rope production, in particular to a straightening device for steel wire rope production. The following proposals are proposed, including a base, a No. 1 straightening cylinder, a No. 2 straightening cylinder and a No. 3 straightening cylinder. The inner walls of the No. 1 straight barrel and the No. 3 straight barrel are fixedly connected with mounting plates at equal distances. In the present invention, by setting a limit adjustment spring, a mounting plate, an arc-shaped guide plate, a collision plate and a hydraulic cylinder, before the wire rope is straightened, the wire rope passes through the No. 1 straightening barrel, the No. 2 straightening barrel and the No. 3 straightening barrel In the middle, the limit adjustment spring is squeezed, so that the balls on the two limit arc plates just fit the outer wall of the wire rope to realize the limit of the wire rope, and then adjust the hydraulic cylinder to drive the collision plate to limit the arc guide plate. Thereby, the fixing of the limit arc plate is realized, and the straightening effect is reduced due to shaking of the limit arc plate during the straightening process of the steel wire rope.
