Embodiment
Be described below in detail embodiment of the present utility model, the example of described embodiment is shown in the drawings, and wherein same or similar label represents same or similar element or has element that is identical or similar functions from start to finish.Being exemplary below by the embodiment be described with reference to the drawings, only for explaining the utility model, and can not being interpreted as restriction of the present utility model.
In description of the present utility model, it will be appreciated that, orientation or the position relationship of the instruction such as term " " center ", " on ", D score, "front", "rear", "left", "right", " vertically ", " level ", " top ", " end " " interior ", " outward " they be based on orientation shown in the drawings or position relationship; be only the utility model and simplified characterization for convenience of description; instead of instruction or imply the device of indication or element must have specific orientation, with specific azimuth configuration and operation, therefore can not be interpreted as restriction of the present utility model.
In description of the present utility model, it should be noted that, unless otherwise clearly defined and limited, term " installation ", " being connected ", " setting " should be interpreted broadly, and such as, can be fixedly linked, arrange, also can be removably connect, arrange, or connect integratedly, arrange.For the ordinary skill in the art, concrete condition the concrete meaning of above-mentioned term in the utility model can be understood.
As shown in Figure 1-Figure 3, the utility model provides a kind of blind hole fastening connection piece, comprising:
Link body, described link body comprises compressible expander 101, through hole 102, it is inner that described through hole runs through described compressible expander, and described link body also comprises blocked part 103, elasticity boss 104, and described blocked part, elasticity boss are arranged on described compressible expander two ends; The inside at described link body two ends is also movably set with nut 1, nut 23, and the hand of spiral of described nut one, nut two is contrary, described nut one, nut two and described through hole concentric;
Stud 4, described stud is provided with thread section 1, thread section 2 402, and described thread section one matches with described nut one, and described thread section two matches with described nut two.
The working procedure of a kind of blind hole fastening connection piece that the utility model provides is: first by link through in the gap of connected piece or blind hole, due to compressible expander 101, the deformable of elasticity boss, rotate stud and elongate compressible expander, thus or can insert in blind hole through less gap; When link body inserts after in blind hole, turn stud in opposite direction, because the hand of spiral in nut one, nut two is contrary, nut one, nut two are drawn close to the center of stud simultaneously, compressible expander is compressed and extrudes hole wall, increases the steadiness of link and connected piece.Turned round about by stud when needing to extract link, nut one, nut two, towards two end motions of stud, can be extracted.
A kind of blind hole fastening connection piece that the utility model provides, realizes tightening with when unclamping, and only needs just can realize from the side of connected piece, not only be applicable to the connection in blind hole, also be particularly suitable for the connection carried out in small space, and structure is simple, installation and removal are all more convenient.
