Description
Technical Field
The utility model relates to the technical field of mechanical tools, in particular to a hose reducing expander.
Background
In the production of electrolytic processes, various pipelines are often required to be connected with an electrolytic tank to complete the transportation of liquid. When the hose is connected with the hard tube, two connecting pipelines are in interference fit to prevent the two connected pipeline connecting parts from falling off under the flowing impact of liquid, so that the inner pipe diameter of the hose connected with each other is slightly smaller than the outer pipe diameter of the hard tube, the hose can be conveniently sleeved on the outer wall of the hard tube, and the hose can firmly wrap the hard tube by means of the elastic pressure of the hose. During actual operation, the operator needs very big strength to be able to sleeve the hose on the hard tube, is sometimes limited by the operating space, can only install by bare hands, wastes time and energy, and still has mechanical injury hidden danger.
Disclosure of utility model
The utility model aims to provide a hose reducing expander, which is characterized in that the end part of a hose is opened by the movement of an expanding claw and is sleeved on the outer wall of a hard pipe, so that time and labor are saved.
In order to achieve the above purpose, the technical scheme adopted by the utility model is as follows:
The utility model provides a hose reducing expander, including front end through axis of rotation interconnect's fixed handle and twist grip, fixed handle is located the top of twist grip, the lower surface at the twist grip is fixed to the bottom of axis of rotation, install the fixed disk in the axis of rotation, the fixed disk is located the upper surface of fixed handle, the symmetry has been seted up a plurality of and axis of rotation looks perpendicular spout on the fixed disk, install the several sliding connection pole in the spout, sliding connection pole's top and expansion claw fixed connection, sliding connection pole's lateral wall articulates the other end of rotating the connecting rod mutually with the one end of rotating the connecting rod and articulates mutually through the round pin axle with the edge of axis of rotation upper surface.
Preferably, the expansion claws are arc-shaped, and the outer diameter of a cylinder formed by closing all the expansion claws is smaller than the inner diameter of the hose to be expanded.
Preferably, the height of the expansion claw is adapted to the length of the connecting part of the two connecting pipes to be connected.
Preferably, the top end of the sliding connecting rod is in threaded connection with the bottom of the expansion claw.
Preferably, the side wall of the free end of the rotating handle is wavy, and anti-skid patterns are formed on the side wall.
When the hose is used, an operator firstly stretches the expansion claw into the end part of the hose to be expanded, gradually rotates the rotating handle to drive the rotating shaft to rotate, the rotating shaft drives the rotating connecting rod and the sliding connecting rod to move, the sliding connecting rod gradually moves towards the edge of the fixed disc in the sliding groove to drive the expansion claw to abut against the inner wall of the hose and gradually prop up the wall of the hose until the wall of the hose is larger than the outer pipe diameter of the hard pipe, the operator reversely rotates the rotating handle to take out the expansion claw from the hose, the operator quickly sleeves the hose on the hard pipe, and the wall of the hose is firmly connected with the hard pipe under the action of self shrinkage.
According to the utility model, through the rotation of the fixed handle and the rotating handle, the mutually linked rotating shaft, the rotating connecting rod, the sliding connecting rod and the expansion claw are driven, so that the expansion of the end part of the hose in a narrow space is realized. Design benefit, it is convenient to use, labour saving and time saving.
According to the utility model, the sliding connecting rod is in threaded connection with the bottom of the expansion claw, and when the part of the hose to be expanded is longer, the expansion claw with longer specification can be replaced.
According to the utility model, the sliding groove is formed in the fixed disc, and the sliding connecting rod can stably move in the upper surface of the end part of the fixed handle and the sliding groove, so that the stability of expansion operation is ensured.
The side wall of the free end of the rotary handle is wavy, and the anti-skid patterns are formed, so that the rotary handle is convenient for operators to grasp and is anti-skid.
