First, by the grip of operator's hand and the special construction of clamp when legacy connector uses, by detection tabs and evaporation Device flange clamps, and labor intensity is big, operation fatiguability；

2nd, since the evaporator flange thickness of different automobile types differs, operator needs the thickness according to flange when detecting The clamping distance of adjustment clamp-type connector back and forth manually, to ensure clamping degree and good seal, therefore inefficiency, and clamps Degree is not easy to control；

3rd, hand adjustment clamp position need to transfer clamping distance back and forth, easy to wear, can not repair to cause to give up after long term wear It abandons；

4th, because on evaporator flange water inlet pipe and water outlet pipe step it is of different sizes, two connectors of matching legacy connector It is also corresponding different when internal diameter designs, therefore legacy connector can only be with a direction, i.e., major part connects big step, microcephaly connects small stair Clamping is combined, such operation convenience versatility aspect is bad, once it is reversed, step can be caused to wear (aluminium alloy system), It is even discarded.

For these purpose is solved the problems, such as, the utility model redesigns a set of detection tabs, is that one kind is used to evaporate The high pressure detection tabs of device helium detection, technical solution are as described below：

A kind of high pressure detection tabs for the detection of evaporator helium, it is described to connect including connector unit and evaporator flange Head unit includes stainless steel square and the first connector, the second connector that are disposed thereon, the first connector and the second connector it Between setting there are two the M6 installation screw threads on M6 hexagon socket head cap screws nail arranged side by side and the evaporator flange to be correspondingly arranged.

First connector, the lower end structure of the second connector are identical, be both provided with the first receiving portion and below second Receiving portion, the second receiving portion are tapered.

A diameter of 14.9mm of first receiving portion.

A diameter of 21.6mm of the second receiving portion most big end.

The labor intensity that new detection tabs provided by the utility model will mitigate operator；Manual operation when reducing detection Product caused by error judges probability by accident；It is a kind of detection tabs of versatility, and the size of the intake-outlet step on flange is not Forward and reverse use of clamp is influenced, and is not influenced by flange thickness, full car type can use；Its structure is simple simultaneously, dimension Shield is convenient, low manufacture cost.

Such detection tabs will be in cost of manufacture, later maintenance cost and raising production efficiency and reduction labor intensity Etc. all play a positive role.

Also, the benefit of the utility model is various：

First, improving operating efficiency, operator is when using legacy clamp, because flange thickness is different and in accordance with disengaging The fearless time can be expended in terms of the direction of the mouth of a river, these times all evade falling when using new clamp because of outstanding design ；

Second is that alleviating the labor intensity of operator, the firmly folder of thousands of times is had when operator is using legacy clamp daily Tight action even the operator that body is strong, can also feel tired at the end of the day, and palm is all callus after long-term operation, and Novel pincers do not need to operator and firmly clamp, and only need to smoothly be fastened on flange, be fixed with the screwdriver for determining torsion；

Three are reduction of cost of manufacture and later maintenance expense, and legacy clamp, monthly can be because falling during normal use It falls, wear discarded and must newly purchase 4~5 sets to replace, cost about 4,5,000, and new machine is simple in structure, is hardly damaged, this Body purchase cost just only has the 80% of legacy clamp, it is contemplated that general two or three months have 1 set of clamp damage, and actually we from Since in March, 16 starts to come into operation, half a year finds no badly damaged clamp more, only replaces some trip bolts, later stage Maintenance cost is very low；

Fourth, improving product quality, legacy clamp is because concentric reducer must be matched with the big small stair of flange, operator Flange step gouge can be caused product abandonment when neglecting clamping direction, and novel pincers have evaded this hidden danger completely, greatly Small stair, both forward and reverse directions are all general, reduce the undesirable cost of quality.
