Abstract
The utility model relates to a rapid pipeline opening expander, which comprises an expansion head, a cone, a rack, a ratchet wheel, a gear, a movable hand grip and a fixed hand grip. The rapid pipeline opening expander is characterized in that the ratchet wheel is connected to the upper end of the movable hand grip, the ratchet wheel is connected with and can be in transmission with the gear on the left side of the ratchet wheel, the fixed hand grip is arranged on the other side of the gear, the rectangular rack is arranged above the gear and connected with the cone nested into an expansion unit, and the expansion head, a spring and a bolt are sequentially arranged on the expansion unit from left to right. The rapid pipeline opening expander has the advantages labor intensity reduction by using transmission between the ratchet wheel and the gear to enable the cone to expand the expansion unit, simple structure, easy carrying and similar suitability for small-scale production and household use.
Description
Technical field
The utility model relates to a kind of pipeline enlarging device, the quick mouth expander of particularly 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 head, cone, tooth bar, ratchet, gear, movable handgrip and integral cast handle, the upper end of movable handgrip connects ratchet, but be connected and transmission between the gear in ratchet and left side, the opposite side of gear is provided with integral cast handle, the top of gear is provided with rectangular tooth bar, and tooth bar is connected with cone, and cone is nested within the expansion elements; Expansion elements is provided with expansion head, spring and bolt from left to right successively; During work, clockwise rotation activity handgrip, then the ratchet driven gear makes tooth bar to left, and then drives cone to left.
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, be fit to small-scale production and family equally and use.
Description of drawings
With reference to the accompanying drawings the utility model is described in further detail below.
Fig. 1 is the agent structure schematic diagram of the quick mouth expander of the described pipeline of the utility model embodiment;
Fig. 2 is the cone external member structural representation of the quick mouth expander of the described pipeline of the utility model embodiment;
Fig. 3 is the plan structure figure 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 1, cone 4, tooth bar 7, ratchet 8, gear 9, movable handgrip 10 and integral cast handle 11, the upper end of movable handgrip 10 connects ratchet 8, but be connected and transmission between the gear 9 in ratchet 8 and 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 rectangular tooth bar 7, tooth bar 7 is connected with cone 4, and the one end is provided with latch 6, the front portion of joint 5 is provided with cone 4, and cone 4 is nested within the expansion elements 12; Described expansion elements 12 is provided with expansion 1, spring 2 and bolt 3 from left to right successively.
The quick mouth expander of the described pipeline of above the utility model embodiment, under the situation of not working, 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, ratchet 8 driven gears 9 then, make tooth bar 7 to left, and then drive cone 4 to left, because of the special shape of cone 4, make expansion elements produce good expansion effect, thereby can expand the PEX pipe.
