An automatic unlocking device for assembling a headrest
An automatic headrest unlocking device for assembly includes a frame with a positioning seat, an unlocking mechanism, and a separation mechanism mounted on it. The unlocking and separation mechanisms are located between the headrest and the positioning seat, and are connected to a control module via wiring. The application method is as follows: place the headrest on the positioning seat; activate the automatic unlocking device, causing a lever to extend into the unlocking notch and connect to an elastic element; drive the corresponding lever via a lever drive mechanism to disengage the elastic element from the headrest's limiting groove; push the headrest away from the positioning seat via the separation mechanism; reset the lever and disengage it from the elastic element, then be driven back to its initial position by the lever drive mechanism; finally, remove the headrest from the headrest. The advantages of this invention are: automatic separation of the headrest and headrest, saving time and effort, and great convenience.

PCA automatic control device
ActiveCN224207175Uincrease elasticityeasy to useInfusion devicesFlow controlKey pressingAutomatic control
The utility model discloses a PCA automatic control device comprising a pipeline which comprises a flow limiting pipe, a liquid storage bag and an elastic pipe which are communicated in sequence. The base is of a shell structure with an opening in the upper end face, and a pipeline groove used for containing the pipeline is formed in the base. The key is rotationally connected with the base, the left side of the key is provided with an interceptor plate extending downwards, and the right side of the key is provided with a pressing part extending downwards; the reset assembly is used for providing reset force for anticlockwise rotation of the key; the locking assembly comprises a locking piece and an operating piece which are connected with each other; in the assembling stage, the locking assembly stops the key from rotating anticlockwise, so that the intercepting plate is in the state of not extruding the elastic pipe; in the use stage, external force is applied to the operating piece, and the locking piece relieves blocking of the key; in the liquid medicine adding stage, the pressing part moves downwards, the key rotates clockwise, the pressing part extrudes the liquid storage bag, and the intercepting plate is far away from the pressing elastic pipe. The locking assembly protects the elastic tube from being squeezed in the long-time storage process after being assembled.

A pickup truck bed tarp that is easy to secure
This utility model discloses a pickup truck bed rain cover that is easy to secure, including a cover cloth, a first ratchet tensioner, and a second ratchet tensioner. Double securing straps are connected to both sides of the cover cloth near the front end, and single securing straps are connected to the side and rear edges of the cover cloth. A long nylon strap is connected to the first ratchet tensioner. This pickup truck bed rain cover can be hung on the side of the pickup truck using hooks. The single securing strap is then passed through the insertion hole in the middle of the tightening shaft of the first ratchet tensioner. The tightening lever of the first ratchet tensioner can then be cranked, causing the tightening shaft to wrap around and tighten the single securing strap, which is then locked in one direction by the ratchet to prevent it from loosening. This makes securing the pickup truck bed rain cover quicker, simpler, more secure, and safer, avoiding the risk of hand injury from manual tightening.
