Description
Technical Field
The utility model relates to a test utensil technical field, in particular to spanner for installing oxygen flow meter.
Background
In clinical work, in order to correct the oxygen deficiency state of the organism, oxygen is usually inhaled to a patient, and an oxygen cylinder is one of the common oxygen sources for clinical oxygen supply. When the oxygen flow meter is used, the oxygen flow meter is required to be connected with an oxygen steel cylinder, and then the oxygen flow is regulated according to the advice of a doctor, in order to ensure the tightness of the connection and prevent oxygen leakage, a nut on the oxygen flow meter is often required to be tightly screwed on the oxygen steel cylinder by a wrench, and when the oxygen flow meter is screwed down, the distance between clamping teeth of the wrench is required to be regulated after the wrench is placed on the nut, so that the time is wasted; after the oxygen flowmeter is screwed down, the spanner needs to be placed at a fixed position or on the oxygen steel cylinder, the spanner needs to be taken by medical personnel when the oxygen flowmeter is installed and taken down, and the workload of the medical personnel is increased; because the structure that does not have the spanner that hangs on the oxygen steel bottle often ties up the spanner with the rope after again and hangs on the oxygen steel bottle, because do not have zonulae occludens between spanner and the steel bottle, when taking the spanner or moving the oxygen steel bottle, the spanner collides with the steel bottle and causes the anti-rust paint on oxygen steel bottle surface to drop, and the collision sends noise influence patient's rest. People nearby the oxygen steel cylinder are easily injured by smashing after the rope of the suspension wrench is broken.
Disclosure of Invention
The utility model aims to solve the technical problem that a spanner for installing oxygen flow meter is provided, this spanner flexibility is strong, user experience is good.
A spanner for installing oxygen flow meter include: a handle having magnetic properties; the magnetic wrench body is provided with a C-shaped notch for the hexagon nut to enter the wrench body on the outer side, and the polygonal structure on the inner side; the wrench body consists of a plurality of clamping teeth; the handle is connected with the wrench body.
According to a further feature of the wrench for mounting an oxygen flow meter of the present invention, the handle is a rectangular parallelepiped, the surface of which has a plastic layer; the handle is provided with a plurality of hexagonal holes with different diameters, and the hexagonal holes correspond to hexagonal nuts with different specifications and can be used for screwing the hexagonal nuts with different specifications; the tail end of the handle is provided with a rectangular hole. The rectangular hole can be used for passing through a rope to hang a wrench on an oxygen steel cylinder and can also be used for screwing a butterfly nut.
According to a further feature of the wrench for mounting an oxygen flow meter of the present invention, the latch comprises a movable latch, a spring, and a fixed latch; the movable latch is positioned in the middle of the fixed latch, and the spring is arranged between the movable latch and the fixed latch, so that the movable latch can stretch out and draw back in the fixed latch.
According to a further characteristic of spanner for installing oxygen flow meter, the activity latch is isosceles trapezoid, consequently conveniently the activity latch returns and contracts to prevent that the activity latch from droing from fixed latch.
According to a further feature of the spanner for installing oxygen flow meter, the fixed latch has hollow bilayer structure.
A spanner for installing oxygen flow meter have following beneficial effect:
(1) the handle and the wrench body are magnetic, and can comprise magnetic materials, or be made of magnetic materials, or be made to be magnetic in an electromagnetic ring mode. Consequently, can make on the spanner adsorbs the oxygen steel bottle or on the oxygen transport vechicle, can avoid when moving the oxygen steel bottle, the spanner collides with the steel bottle and makes the anti-rust paint on oxygen steel bottle surface drop and send noise influence patient's rest simultaneously. Because adsorb on the oxygen cylinder, can prevent when the rope fracture back that hangs that the spanner from falling and injures personnel on every side.
(2) The handle surface can have the one deck plastic layer for this device adsorbs provides the cushioning effect to the impact of anti-rust paint when oxygen steel bottle, and the anti-rust paint on protection oxygen steel bottle surface has thermal-insulated effect simultaneously, increases user's comfort under low temperature environment.
(3) The latch comprises activity latch, spring, fixed latch, and the activity latch can stretch out and draw back in fixed latch, and the spring in the latch is compressed according to the size of nut, and the interval of activity latch and fixed latch reduces, and the length of latch reduces, makes the interval between two latches on the diagonal line unanimous with the diameter of nut on the spanner body to the spacing that can automatically regulated latch on making the spanner body can be according to the nut size. Meanwhile, the spring in the latch enables the movable latch to be tightly attached to the nut, so that slipping is prevented when the nut is screwed. Particularly, when the hexagonal nut is placed in the wrench body, the diameter of the hexagonal nut is larger than the distance between the movable clamping teeth on the diagonal line of the wrench body, the nut compresses the spring between the movable clamping teeth and the fixed clamping teeth, the movable clamping teeth enter the fixed clamping teeth, the distance between the movable clamping teeth on the diagonal line of the wrench body is increased, and meanwhile the spring enables the movable clamping teeth to be tightly attached to the hexagonal nut, so that the distance between the clamping teeth can be automatically adjusted according to the diameter of the placed hexagonal nut.
To sum up, a spanner for installing oxygen flow meter safe practical, the flexibility is strong, user experience is fabulous, convenient to use practices thrift medical personnel's time.
