Abstract

The utility model relates to a rapid tube expander, which comprises an expansion unit, a cone, a rack, a ratchet, a gear wheel, a movable handle and a fixed handle, wherein, the upper end of the movable handle is connected with the ratchet; the ratchet is engaged with the gear wheel on the left side thereof; the fixed handle with fixing and holding function is arranged at the other side of the gear wheel; the strip-shaped rack is arranged on the gear wheel; the lower side of the rack is engaged with the gear wheel; the left side of the rack is connected with the cone through a pin; the expansion unit is composed of an expansion head and a spring arranged inside the expansion head; the expansion head is connected with the cone through a bolt and a joint; and the cone is embedded in the expansion head. The utility model has the advantages that the transmission between the ratchet and the gear wheel allows the cone to expand the expansion unit, thereby reducing the labor intensity; at the same time, the utility model has simple structure and easy carrying.

Description

The quick mouth expander of a kind of pipeline

Technical field

The utility model relates to the quick mouth expander of a kind of pipeline.

Background technology

Usually connecting or during the processing metal pipe fitting, the bore of one of them termination of two pipe fittings need amplified, can realize simple plug-in mounting and socket thus.Traditional zinc-plated pipe fitting is replaced by present free of contamination plastic pipe, and the reliability that structure connects between every section of this kind pipe fitting is lower, does not reach good result of use; Therefore, need to use some flaring tools, some situation is used the instrument of multiple loose mail type, and its site operation difficulty is inconvenient to carry and preserve; The flaring tool that some are complicated, it is bulky and heavy, is not suitable for small-scale production and family and uses; The flaring tool that some is special-purpose, the horn mouth shape that it processes is not of uniform size, needs the defective of excessive torsion when existing rotation, causes operating efficiency lower.

The utility model content

The purpose of this utility model provides the quick mouth expander of a kind of pipeline,, complex structure big with the operating force that overcomes existing mouth expander, is inconvenient to carry and preservation, the restricted deficiency of the scope of application.

The purpose of this utility model is to be achieved through the following technical solutions:

The quick mouth expander of a kind of pipeline, comprise expansion elements, cone, tooth bar, ratchet, gear, movable handgrip and integral cast handle, the upper end of movable handgrip is connected with ratchet, be meshing with each other and be connected between the gear in ratchet and its left side, the opposite side of gear has been provided with the integral cast handle of the effect of fixedly holding, the top of gear is provided with the tooth bar of strip, and being meshing with each other between the downside of tooth bar and the gear is connected, and the latch that passes on left of tooth bar is connected with cone; Expansion elements is made of expansion head and spring, and it is inner that spring is arranged on the expansion head, and the expansion head is connected with cone by bolt and joint, and cone is nested in the expansion head.Under working condition not, gear, ratchet, tooth bar all keep Static Contact; When starting working, can hold integral cast handle clockwise rotation activity handgrip simultaneously, then the ratchet driven gear rotates and makes tooth bar to left, and then the drive cone makes that to left expanding head produces good expansion effect, manages thereby can expand PEX.

The beneficial effect of the quick mouth expander of pipeline described in the utility model is: utilize the transmission between ratchet and the gear that cone is expanded expansion elements, thereby reach the effect of expansion PEX pipe; The transmission of power increases, and has alleviated labour intensity; Simple in structure, be easy to carry about with one.

Description of drawings

With reference to the accompanying drawings the utility model is described in further detail below.

Fig. 2 is the cone structure schematic diagram of the quick mouth expander of the described pipeline of the utility model embodiment;

Fig. 3 is the vertical view of the quick mouth expander of the described pipeline of the utility model embodiment.

Among the figure:

1, expansion head; 2, spring; 3, bolt; 4, cone; 5, joint; 6, latch; 7, tooth bar; 8, ratchet; 9, gear; 10, movable handgrip; 11, integral cast handle; 12, expansion elements.

The specific embodiment

As Figure 1-3, the quick mouth expander of the described pipeline of the utility model embodiment, comprise expansion elements 12, cone 4, tooth bar 7, ratchet 8, gear 9, movable handgrip 10 and integral cast handle 11, the upper end of movable handgrip 10 is connected with ratchet 8, be meshing with each other and be connected between the gear 9 in ratchet 8 and its left side, the opposite side of gear 9 has been provided with the integral cast handle 11 of the effect of fixedly holding, the top of gear 9 is provided with the tooth bar 7 of strip, being meshing with each other between the downside of tooth bar 7 and the gear 9 is connected, and the latch 6 that passes on left of tooth bar 7 is connected with cone 4; Expansion elements 12 is made of expansion 1 and spring 2, and spring 2 is arranged on expansion 1 inside, and expansion 1 is connected with cone 4 by bolt 3 and joint 5, and cone 4 is nested in to be expanded in 1.

Under working condition not, gear 9, ratchet 8, tooth bar 7 all keep Static Contact; When starting working, can be when holding integral cast handle 11, clockwise rotation activity handgrip 10, then ratchet 8 driven gears 9 rotate, and make tooth bar 7 to left, and then drive cone 4 to left, make and expand a good expansion effect of 1 generation, thereby can expand the PEX pipe.
