6results about How to "Put in smoothly" patented technology

The utility model relates to the technical field of medical instruments. The blood routine examination sample container comprises a bottom plate, friction pads are fixedly connected to the four corners of the bottom end of the bottom plate, a connecting structure is arranged in the bottom plate, a containing cylinder is fixedly connected to the surface of the top end of the bottom plate, and a clamping structure is arranged in the containing cylinder. According to the blood sample test tube placing device, a pull rod is sequentially pulled outwards, when the pulling force is larger than the elastic force of a second spring, a movable plate can synchronously move along with the pull rod, so that a supporting plate and a clamping plate are driven to synchronously move outwards, and a blood sample test tube is placed in a placing barrel until a space with enough size is reserved in the placing barrel; at the moment, a pull rod is slowly loosened, clamping plates on the two sides can be pushed towards the inner side under the action of self elasticity of a second spring, and the blood sample test tube can be more smoothly placed into a placing barrel by adjusting the positions of the clamping plates.

This invention belongs to the field of surgical instrument technology and discloses a disposable sterile specimen retrieval bag with spill prevention, comprising a cannula, a push rod, and a specimen bag. The push rod is slidably connected inside the cannula, and the specimen bag is connected to one end of the push rod. The specimen bag includes a support strap with several ratchet teeth on one side. One end of the support strap is connected to a buckle, and the buckle has protrusions that match the ratchet teeth. The other end of the support strap passes through the buckle. The support strap and the buckle form an elastic annular support ring. A hollow sleeve is fitted onto the annular support ring, with one end connected to the end of the support strap and the other end connected to the buckle. The hollow sleeve is connected to the retrieval bag body. This invention solves the technical problems of existing specimen bags having limited options for aperture specifications, being easily damaged, and having a semi-closed opening that hinders the smooth placement of specimens.

The utility model relates to dry powder fire extinguisher technical field discloses an easily fixed portable dry powder fire extinguisher, including support frame, the inside fixed connection of support frame has the fixed plate, the outside fixed connection of fixed plate has fixed block, the inside rotatory connection of fixed block has two clamping blocks, the outside fixed connection of fixed plate has two springs, the other end of two spring all is fixedly connected with the connecting plate, the similar side of two clamping blocks is installed with the clamping block, the outer wall fixed connection of clamping block has the support plate, the outer wall fixed connection of support plate has the fire extinguisher body. In the utility model, after the fire extinguisher body is put into the base and is clamped into the snap ring, the external clamping block will be clamped into the two clamping blocks of support frame, the connecting plate outside the clamping block is connected with the fixed plate through the spring, the elastic potential energy of spring drives the connecting plate, drives the clamping block tight clamping clamping block, and the fire extinguisher body is fixed in this way, and is placed more stable on the base.

The utility model provides a kind of fastener clamp of tension testing device, including main shaft, multiple clamping jaw, taper head top block;Main shaft includes threaded section and installation section, installation section is integrally formed in the bottom of threaded section;Multiple scallop bodies are integrally formed on the outer periphery of installation section, and clamping jaw installation groove is formed between adjacent scallop bodies, and clamping jaw is rotatably connected with scallop body by pivot;The axis of taper head top block is connected to the outside of threaded section by screw thread, and the inner wall of the upper portion of clamping jaw is formed with the abutting bevel for cooperating with taper head top block. Through the design of high integration integrated main shaft and scallop body, excellent structural rigidity and strength are provided, the taper-screw driving mechanism is used to realize efficient, synchronous, powerful and uniform clamping and loosening operation of clamping jaw, and excellent self-centering ability is provided to adapt to different size fasteners.

The utility model discloses a tray for long valve plate processing, including positioning mechanism and tray main part, and positioning mechanism is by first locating seat, first connecting plate, second locating seat, and first connecting plate forms U -shaped groove with first locating seat and second locating seat are connected, and at least two first locating pins are fixed to first locating seat and set up upwards along the inside and outside direction, and the outside of first locating seat is fixed to set up upwards first limit baffle with, and at least two second locating pins are fixed to second locating seat and set up upwards along the inside and outside direction, and the outside of second locating seat is fixed to set up upwards second limit baffle with, and tray main part includes tray and support leg, and two rows of clamps are set up symmetrically upwards in the both sides of tray respectively, and support leg sets up in the bottom both sides of tray respectively, and the bottom both sides of tray still are provided with first locating hole with the position of first locating pin corresponds and second locating hole with the position of second locating pin corresponds, and tray main part is positioned and places in U -shaped groove.

This utility model relates to the field of automatic feeding technology and discloses an automatic bar feeding device, including a machine body with a lifting assembly and a ramp-shaped feeding plate. The lifting assembly includes a lifting plate, a receiving component, and an ejector component. The lifting plate is vertically movable and located at the front end of the ramp-shaped top of the feeding plate. The receiving component is connected to the lifting plate and is used to receive the bar material placed from the outside. The ejector component is rotatably connected to the lifting plate, and the ramp-shaped top of the feeding plate is adapted to abut against the ejector component. When the bar material is placed on the receiving component, the lifting plate moves down, causing the feeding plate to abut against the ejector component, which then swings upward to eject the bar material from the receiving component, allowing the bar material to roll down the feeding plate. By reducing the descent height of the bar material through the lifting plate, damage caused by the bar material rolling from an excessive height is prevented. The ejector component descends with the lifting plate and rotates upward during the descent, ejecting the bar material from the receiving component. The structure is simple and ingenious, and the cost is low.
