Detailed description of the invention
By the description below with reference to attached drawing to the utility model embodiment, the above-mentioned and other mesh of the utility model
, feature and advantage it is apparent, in the accompanying drawings:
Fig. 1 is the structural schematic diagram that the taper of the utility model embodiment tests that envelope unloads crimp head.
Specific embodiment
The utility model is described below based on embodiment, but it is worth noting that, the utility model is simultaneously unlimited
In these embodiments.It is detailed to describe some specific detail sections below in the datail description of the utility model.So
And for the part of no detailed description, the utility model can also be understood completely in those skilled in the art.
In addition, it should be understood by one skilled in the art that provided attached drawing is simply to illustrate that the utility model
Objects, features and advantages, attached drawing are not to be actually drawn to scale.
Meanwhile unless the context clearly requires otherwise, "include", "comprise" etc. otherwise throughout the specification and claims
Similar word should be construed as the meaning for including rather than exclusive or exhaustive meaning；That is, being " including but not limited to "
Meaning.
Fig. 1 is the structural schematic diagram that the taper of the utility model embodiment tests that envelope unloads crimp head.As shown in Figure 1: a kind of cone
Shape tests envelope and unloads crimp head, including top connection 1, lower contact 6 and connector 10, top connection 1 are threadedly coupled with connector 10；Lower contact
6 are connect with top connection 1 by elastic locking mechanism, while utilizing conical surface seal with connector 10.In use, top connection 1 and pressure
Power meter is threadedly coupled, and lower contact 6 is threadedly coupled with seal section.
Further, elastic locking mechanism is fixed on the lower end of lower contact 1, including steel ball 5, spring 4 and fixed lid 3；Bullet
4 both ends of spring connect steel ball 5 and fixed lid 3；Card slot is arranged in the upper end of top connection 1, and card slot and the cooperation of steel ball 5 constitute sealed connection
It is secondary.Card slot and the sealed connection of steel ball 5, prevent upper and lower pressure difference from opening the connection between top connection and lower contact, and sealing is caused to lose
It loses.
Further, in Fig. 1, the first sealing ring 8 is arranged in the external screw thread root of lower contact 1, which is used for
Seal section screw thread is prevented to be buckled to.
