Abstract
The invention discloses a movable-type emergency stretcher pulley. The movable-type emergency stretcher pulley comprises a pair of triangular fixed base plates which are arranged in parallel, wherein detachable rollers are respectively arranged among three angles of the pair of fixed base plates, a fixed pivot is arranged at the centers of the pair of fixed base plates, and the top of the fixed pivot is provided with a locking inclined plane. The movable-type emergency stretcher pulley has the advantages that the detachable rollers are arranged among the three angles of the fixed base plates, so that two of the rollers are always in contact with the ground in the sliding process, and the smoothness and the shock resistance of the stretcher are greatly improved; and in addition, as the radius of each roller is greater than or equal to that of the fixed pivot, once the rollers need to pass through steps, users can overturn the rollers with relatively small force, therefore, the usability of the stretcher is greatly improved, and the stretcher has strong practicability.
Description
Technical Field
The invention relates to medical equipment, in particular to a movable emergency stretcher pulley.
Background
The movable emergency stretcher is a common stretcher, a foldable support is arranged at the bottom of the stretcher, and rollers are respectively arranged at four corners of the support. The rollers of the prior emergency stretcher are generally common industrial pulleys, when the stretcher passes through steps or bumpy roads, the vibration of the stretcher is large, medical personnel can push the whole stretcher with large strength, and the comfort of patients is also influenced.
Disclosure of Invention
The invention mainly solves the technical problems in the prior art, and provides a movable emergency stretcher pulley.
The technical problem of the invention is mainly solved by the following technical scheme:
the utility model provides a portable first aid stretcher pulley, portable first aid stretcher pulley contain a pair of parallel arrangement's triangle-shaped's fixed base plate, this pair of three angle of fixed base plate between be equipped with a detachable roller respectively, this pair of fixed base plate's center be equipped with a fixed pivot, the top of fixed pivot be equipped with a locking inclined plane.
As a preferred embodiment of the present invention, the radius of the roller is greater than or equal to the radius of the fixed pivot.
As a preferred embodiment of the invention, the roller is made of nylon.
The movable emergency stretcher pulley disclosed by the invention utilizes the detachable roller rollers on the three corners of the fixed base plate, so that two roller rollers are always in contact with the ground in the sliding process, and the stability and the shock resistance of the stretcher are greatly improved. In addition, as the radius of the roller is larger than or equal to the fixed pivot, once the roller needs to pass through a step, a user can turn the roller by only needing small force, so that the usability of the stretcher is greatly improved, and the stretcher is strong in practicability.
