Q: What are tensile and shrink wrapping?: Stretching: one of the basic characteristics. The tensile feature is to draw the cross section of the drawn cross section in a specified tensile direction at a specified depth. Stretching is the most commonly used entity creation type that is suitable for creating rule entities and should be skilled.The main purpose: contraction of envelope: complex parts or components 1. can be used as a reference or package model to create a lightweight version; 2. can be used to create geometric model sharing relationship with suppliers and customers, and get rid of what you don't want to share details; file - save a copy - type contraction envelope; create components, in the form of a activation element inserts - shared data - shrinkwrap -- referring to the type for the components of a subset of context.

Q: Is the construction of the water supply steel pipe a telescopic device?: After completion of the individual project, the pipe top elevation and control point coordinate shall be measured before completion of the trench backfill, and the completed measurement result sheet shall be drawn, and the completed drawing shall be drawn accordingly.

Q: How to achieve telescopic power arm: Pneumatic, cylinder. There is an electromagnetic valve, an air compressor.

Q: Mechanical structure and principle of automatic focusing lens for camera: Ultrasonic ranging method, which is based on the ultrasonic wave in the digital camera and the time between the subject of distance measurement. Digital cameras are equipped with ultrasonic transmitting and receiving device, when the ultrasonic vibration generator for ultrasonic, ultrasonic to the subject, is the receiver's perception of return immediately, and then by the integrated circuit according to the ultrasonic round-trip time to calculate the focusing distance.

Q: What are the main uses of a bolt tensioner?: Stretch, fasten, or loosen the bolts and think of the bolts as a rubber band,

Q: Mechanical principle of belt expansion machine: Principle: the telescopic belt conveyor adds a telescopic mechanism to the ordinary belt conveyor, so that the belt conveyor can be freely extended in the length direction.

Q: What is a bolt tensioner? How do you use it?: The bolt tensioner is a tool for fastening and dismounting bolts. It has several forms, such as manual, electric, pneumatic, hydraulic and so onBolt tensile bolts and shear bolts, tensile bolts subjected to tensile load is axial load; shear bolts subject to shear load, tangentialThe bolt load is the force acting on the bolt, which is usually expressed by pressure, that is, the force / force acting areaThe so-called pre tightening force is a force in the mounting bolt in the bolt on the pre action (Ya Qiang), its role is to enable the bolt force and deformation, the fasteners are combined together, and can prevent the bolt fracture under impact load.Note: the preload and bolt load are less than the rated load of the bolt

Q: How do you pull the contracted muscles with a mechanical device?: A muscular spasm is a controlled contraction that causes the muscles to be tense and rigid, usually caused by lactic acid accumulation. 1) massage the muscles. 2) gently pull the muscles. Namely: 1 spasms can occur in any muscle, usually caused by unaccustomed activity, often occurring in the calf muscles of the gastrocnemius. When you massage, the injured must sit or lie down. 2 gently pull the muscles to counteract the spasms, and pull the foot to the shin in this case. Massaging and pulling muscles can increase the flow of blood in the muscle to take away and disperse the local lactate. Muscle spasm first aid Beijing Morning Post muscle spasm is commonly known as cramping. It is an involuntary tonic contraction produced by the muscles.

Q: What is the automatic telescopic function of an automatic umbrella?: When the intermediate slider is moved upwards, the switch is moved upward to prevent the spring 2 from compressing the spring at the lower dead point position and the elasticity does not reach the maximum value. Only when the switch force is slightly greater than the maximum value of spring 2 elasticity, the convex switch is retracted, and the middle slider begins to move up.B. when the middle slider moves down, the upper half of the convex switch is smaller, so that the spring 1 has sufficient elasticity to make the middle slide switch locked by the convex point switch. And 2, 3 is not enough to cause the umbrella middle slider has been declining.

Q: What are the main uses of a bolt tensioner?: Stretch, fasten, or loosen the bolt and think of the bolt as a rubber band. It is flexible and can be stretched freely within its range of elastic deformation
