This application discloses a quick-clamping planar structure for an elliptical camshaft end, relating to the field of camshaft technology. It includes a base plate with a pair of placement plates on its top surface. Each placement plate has an arc-shaped groove for engaging both ends of the camshaft. A movable block is positioned between the placement plates on the base plate, and the movable block has a pair of fixed clamping plates. One of the fixed clamping plates has a movable plate, and a guide rod extends through the fixed clamping plate. An adjusting rod is threaded onto the fixed clamping plate. The movable plate, in conjunction with the fixed clamping plate, clamps and fixes one cam of the camshaft. The combination of the fixed clamping plate, movable plate, guide rod, and adjusting rod can clamp and fix the cam in the middle of the camshaft. The increased clamping point in the middle effectively constrains the camshaft's circumferential and radial degrees of freedom, reducing minor shaking or twisting during machining or vibration, thereby improving machining accuracy and reducing dimensional deviations.

The present invention discloses a microbial repair agent particle for a crack self-repairing cement-based material and a preparation method thereof. The repair agent particle has a core-shell structure and comprises a microbial repair agent core and a repair agent shell. The repair agent core comprises the following components by mass percentage: microbial powder: 10-15 parts, calcium source: 0.75-1.25 parts, nutrient: 2-3 parts, filler: 8-10 parts; the repair agent shell comprises the following components by mass percentage: sulfoaluminate cement: 6-8 parts, density adjustment powder: 1-3 parts, fly ash: 0-1 part. The present invention changes the formula of the repair agent core and adopts an extrusion granulation method to prepare the core particles, achieving a high loading rate of the microbial component in the core and a small particle size distribution coefficient of the core. At the same time, the repair agent particle has good sphericity, concentrated size distribution, small deviation of particle strength, uniform wall thickness, high yield rate, good responsiveness to cracking and good self-repairing effect on cracks in cement-based materials such as mortar and concrete.

This utility model relates to the field of tire manufacturing technology. It provides a tire carcass comprising an inner support portion, a rim, and support units. The rim is annular and concentrically arranged with the inner support portion. A support space is formed between the inner sidewall of the rim and the outer sidewall of the support portion. The outer sidewall of the rim abuts against the inner surface of the tire to support the tire. Multiple support units are provided on the outer sidewall of the inner support portion. The two ends of each support unit abut against the inner sidewall of the rim and the outer sidewall of the inner support portion, respectively. The inner support portion, support units, and rim are integrally formed. This utility model also provides a cross-linked foamed tire, comprising a tire carcass and an outer tire mounted on the tire carcass. Through the above technical solutions, the carcass structure can be installed without splicing, forming a continuous whole. This solves the technical problem in the prior art where traditional split tire carcasses rely on splicing processes, and stress concentration points easily form at the splicing points, leading to delamination of the tire carcass under high loads or complex working conditions.
