Abstract
The utility model discloses a kind of bridge piece for car heat exchanger, comprise base and connecting tube, described base and the split type connection of described connecting tube, wherein, one end of described base is provided with internal thread, its outer surface is provided with the first reference line, one end of described connecting tube is provided with outside thread, its outer surface is provided with the second reference line, described internal thread and described outside thread cooperatively interact, after described base and described connecting tube are in place, described first reference line and described second reference line coincide, and be also provided with seal ring between described base and described connecting tube.The utility model is by adopting split type connection by base and connecting tube, fixing tooth can first disposable withhold put in place after, again base is fixedly connected with connecting tube, overcome gradation and withhold the defect that the quality of product that causes not easily ensures, and its injection mold structure is simple, the circulating inside cross section of bend part increases, and resistance is little, and product performance improve.
Description
Technical field
The utility model relates to automobile heat exchanger technical field, particularly relates to a kind of bridge piece for car heat exchanger.
Background technique
Bridge piece on the plastic water chamber of car heat exchanger is when injection molded, and the mould due to bend part is that two slide blocks are connected, when it is shaped, slide block is the demoulding from different directions, this technology mode easily causes cross section, inner side of elbow position to diminish, and when fluid passes through, resistance is large, affects product performance.Further, the bend part due to bridge piece has certain angle, and bridge piece is easily withholding generation interference in fixing tooth process, and fixing tooth can not once be press-fit into place.
Model utility content
The utility model mainly to solve in prior art existing technical problem, thus provides one that fixing tooth can be made once to be press-fit into place and injection mold structure is simple, less investment, the bridge piece for car heat exchanger of good economy performance.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
The bridge piece for car heat exchanger that the utility model provides, comprise base and connecting tube, described base and the split type connection of described connecting tube, wherein, one end of described base is provided with internal thread, its outer surface is provided with the first reference line, one end of described connecting tube is provided with outside thread, its outer surface is provided with the second reference line, described internal thread and described outside thread cooperatively interact, after described base and described connecting tube are in place, described first reference line and described second reference line coincide, and are also provided with seal ring between described base and described connecting tube.
Further, described base is with female one end be also provided with a locating slot, described locating slot is used for fixing described seal ring.
Further, described internal thread and described outside thread also scribble nylon glue.
Further, described nylon glue adds flux by nylon PA66 and forms through high-temperature fusion.
Further, described base and connecting tube adopt nylon PA66-GF30 to be made, and described seal ring 7 adopts ethylene propylene diene rubber EPDM to be made.
The beneficial effects of the utility model are: by base and connecting tube are adopted split type connection, fixing tooth can first disposable withhold put in place after, again base is fixedly connected with connecting tube, overcome gradation and withhold the defect that the quality of product that causes not easily ensures, and its injection mold structure is simple, the circulating inside cross section of bend part increases, and resistance is little, and product performance improve.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the plan view of the bridge piece for car heat exchanger of the present utility model;
Fig. 2 is the plan view of the bridge piece for car heat exchanger of the present utility model;
Fig. 3 is the sectional view of Fig. 2 along A-A line;
Fig. 4 is the partial enlarged drawing at the B place of Fig. 3.
Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, to make advantage of the present utility model and feature can be easier to be readily appreciated by one skilled in the art, thus more explicit defining is made to protection domain of the present utility model.
Consult shown in Fig. 1-4, bridge piece for car heat exchanger of the present utility model, comprise base 1 and connecting tube 2, base 1 and the split type connection of connecting tube 2, wherein, one end of base 1 is provided with internal thread 3, its outer surface is provided with the first reference line 4, one end of connecting tube 2 is provided with outside thread 5, its outer surface is provided with the second reference line 6, and internal thread 3 and outside thread 5 cooperatively interact, after base 1 and connecting tube 2 are in place, first reference line 4 and the second reference line 6 coincide, and are also provided with seal ring 7 between base 1 and connecting tube 2.In the utility model, the first reference line 4 is set and the second reference line 6 is to make base 1 and connecting tube 2 reach predetermined angular requirement.And because base 1 and connecting tube 2 adopt split type connection, identical at caliber, the part that angle is inconsistent and position is different, can use same connecting tube, versatility is stronger simultaneously.
Concrete, base 1 is also provided with a locating slot 8 with one end of internal thread 3, and locating slot 8 is for fixed seal ring 7, and seal ring 7 relies on connecting tube 2 to screw to carry out the decrement being pressed to regulation, plays main seal effect.Preferably, internal thread 3 and outside thread 5 also scribble nylon glue 9.Nylon glue 9 adds flux by nylon PA66 and forms through high-temperature fusion.Nylon glue 9 plays filling and secondary seal effect after solidifying.Preferably, base 1 and connecting tube 2 adopt nylon PA66-GF30 to be made, and seal ring 7 adopts ethylene propylene diene rubber EPDM to be made.
The utility model is by adopting split type connection by base 1 and connecting tube 2, fixing tooth can first disposable withhold put in place after, again base 1 is fixedly connected with connecting tube 2, overcome gradation and withhold the defect that the quality of product that causes not easily ensures, and its injection mold structure is simple, the circulating inside cross section of bend part increases, and resistance is little, and product performance improve.
Above, be only embodiment of the present utility model, but protection domain of the present utility model is not limited thereto, any change of expecting without creative work or replacement, all should be encompassed within protection domain of the present utility model.Therefore, the protection domain that protection domain of the present utility model should limit with claims is as the criterion.
