Injection device

An injection device including a syringe having a needle, a barrel and a plunger. The device is configured to provide an automatic injection cycle and includes a drive coupling arrangement between a driving spring and the syringe. In operation, a drive force can be selectively transmitted between the respective first and second parts of the drive coupling arrangement depending upon their relative rotational positions such that, when the first and second parts are in a first relative rotational position during the dispensing stage, a driving force is transmitted to the plunger to drive the plunger into the barrel, and, when the first and second parts are in a second relative rotational position during the retraction stage, no force is transmitted to the plunger to allow the plunger and the syringe to retract.

Creep age forming method for aluminium alloy plate

ActiveCN106978578AReduce distanceReduce laying processVacuum pumpingTest material
The invention provides a creep age forming method for an aluminium alloy plate. The method comprises the steps as follows: a to-be-formed component is arranged on the molded surface of a mold firstly, and parts (the whole lower surface and the peripheral edge of the upper surface) of the component are covered with air-permeable felt; a plate is bent downwards by a mechanical loading device, and the mechanical loading device stops moving downwards after reaching the set force value; the load is unchanged, at least one circle of a sealant is sequentially bonded to the component and the edge of the mold, a vacuum bag is laid and bonded between the sealants, a closed space is formed, vacuum pumping treatment is performed, and the component is almost attached to the molded surface of the mold as far as possible or is kept to be attached to the molded surface of the mold; and then the mechanical loading device is detached, the component and the mold are placed into an autoclave for vacuum creep age forming, and the component and the mold are separated after ageing is completed. With the method, the time required for vacuum pumping is shortened, so that the forming efficiency is improved; less test materials are used, and thus the test cost is reduced; and the mold attaching error is reduced, and accordingly, the forming precision of the component is improved.

Flexible display substrate, display panel and display device

The invention discloses a flexible display substrate, a display panel and a display device. A line in a fixed bending area is formed by sequentially connecting multiple line segments, and the line segments have preset inclination angels with the line extending direction, so that bending stress on the line can be dispersed to the line segments; further, porous structures are arranged on at least part of the line segments, the bending stress dispersed to the line segments can be diffused to edge areas of the porous structures, the bending stress on the line is dispersed to the great extent, and therefore, the risk of fracture or breakage of the line in the fixed bending area is greatly reduced. Besides, a surface contact structure is formed between every two mutually connected line segments, so that multiple contact points are reserved between every two mutually connected line segments, even though fracture or breakage occurs at any contact point, connection of two adjacent line segments can still be realized through the other contact points, and the risk of fracture or breakage of the line is further reduced.
