Description

A kind of Novel perforator

Technical field

The utility model relates to a kind of card punch, and specifically a kind of card punch being applicable to punching on irrigation PE pipe, belongs to card punch equipment technical field.

Background technology

Along with the scarcity day by day of global freshwater resources, now, no matter be irrigate field in field of agricultural irrigation or gardening, having adopted gradually can the drip irrigation of saving water resource more, this irrigation method installs water dropper by the water outlet at water pipe, water yield is reduced, thus reach the object making full use of water resource, day by day universal along with drip irrigation, the erecting tools of people to drip irrigation zone is more and more paid attention to, how improving installation effectiveness is current matter of utmost importance, now widely used card punch is all round end, by strength pressing and the card punch rotation of hand, PE pipe is got hole, this hole knockout is wasted time and energy, efficiency is very low, the new product of my company has the innovation of two aspects, one is by traditional round end, three tips are made into, add local pressure during punching, more easily penetrate PE pipe, after penetrating, only need to rotate handle, just on PE pipe, easily can get circular opening, two is mounting spring structures in handle, to be shaken hands pressing spring by punching, then on the position of PE pipe needing punching, handle is unclamped, the elastic force of spring is utilized to be driven in PE pipe by three tips, change the original pressure by staff, round end is pressed into the method for PE pipe.

Utility model content

For above-mentioned prior art Problems existing, the advantages such as the utility model provides a kind of Novel perforator, has compact conformation, improves perforating efficiency, and the hole of getting is more regular, and sealing is good, by optimizing overall structure, meet different instructions for use.

For achieving the above object, the technical solution adopted in the utility model is: a kind of Novel perforator, and comprise blade, the first perforation, the second perforation, spring, punching handle, core chamber and base, described blade is placed in core chamber by top, core chamber; Described first perforation is arranged on core chamber; Described second perforation is arranged on blade; Described spring is placed in core chamber, and spring upper end is connected with punching handle, and lower end is connected with base; Described base is fixedly mounted on one end, core chamber.

Further, described blade is when putting into core chamber, and in correspondence with each other, punching handle is together through the first perforation and the second perforation, and the second piercing ratio first is bored a hole longer, and width is identical for the first perforation and the second perforation.

Further, described core chamber and base are overall structures.

Further, described blade is provided with protective sleeve.

Further, described punching handle and base are provided with anti-slip veins or are provided with Anti-slip cover.

The beneficial effects of the utility model are: the blade of this Novel perforator is when putting into core chamber, in correspondence with each other, punching handle is together through the first perforation and the second perforation, and the second piercing ratio first is bored a hole longer for first perforation and the second perforation, width is identical, makes overall structure compacter; Described core chamber and base are overall structures, make the better manufacture of overall structure; Described blade is provided with protective sleeve, blade can not be damaged when not using; Described punching handle and base being provided with anti-slip veins or being provided with Anti-slip cover, user can better be used, can not have unexpectedly incident because skidding, and this Novel perforator compact conformation, improves perforating efficiency, and the hole of getting is more regular, sealing is good, is applicable to promoting the use of.

Detailed description of the invention

Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described.Obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.

As shown in Figure 1 to Figure 3: a kind of Novel perforator, comprise blade 1, first perforation 2, second perforation 3, spring 4, punching handle 5, core chamber 6 and base 7, described blade 1 is placed in core chamber 6 by top, core chamber 6; Described first perforation 2 is arranged on core chamber 6; Described second perforation 3 is arranged on blade 1; Described spring 4 is placed in core chamber 6, and spring 4 upper end is connected with punching handle 5, and lower end is connected with base 7; Described base 7 is fixedly mounted on one end, core chamber 6.

As optimisation technique scheme of the present utility model: described blade 1 is when putting into core chamber 6, and 3 in correspondence with each other, punching handle 5 is bored a hole 2 longer together through the first perforation 2 and the second perforation 3, second perforation 3 to the first, width is identical for the first perforation 2 and the second perforation; Described core chamber 6 and base 7 are overall structures; Described blade 1 is provided with protective sleeve; Described punching handle 5 and base 7 are provided with anti-slip veins or are provided with Anti-slip cover.

As production points for attention of the present utility model: to requiring the spring of work times life-span more than 104, checking computations fatigue life of spring should be carried out, particularly require the spring in life-span more than 106, more life-span checking computations will be carried out, in general, working stress is less, and working amplitude is less, then the life-span is longer, therefore, for the spring of high life, enough large space should be reserved when Design of Mechanical Structure as far as possible, reduce the stress amplitude of spring works as far as possible, reduce the maximal work stress of spring.

To those skilled in the art, obvious the utility model is not limited to the details of above-mentioned one exemplary embodiment, and when not deviating from spirit of the present utility model or essential characteristic, can realize the utility model in other specific forms.Therefore, no matter from which point, all should embodiment be regarded as exemplary, and be nonrestrictive, scope of the present utility model is limited by claims instead of above-mentioned explanation, and all changes be therefore intended in the implication of the equivalency by dropping on claim and scope are included in the utility model.Any Reference numeral in claim should be considered as the claim involved by limiting.
