Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described further.
As shown in Figures 1 to 8, a kind of retaining mechanism, comprises bolt 1, lock-screw 2 and latch assembly 3, and latch assembly 3 comprises body 4, sleeve 5 and pushing block 6; Lock-screw 2 is fastened on pushing block 6, and sleeve 5 is sleeved in body 4, and the axial inclusion of the front end of bolt 1 is in sleeve 5, and inclusion portion and the pushing block 6 of bolt 1 and sleeve 5 are radially screwed together by lock-screw 2; Body 4 is provided with pushing block 6 the wedge shape guiding surface 41,61 mating.
Embodiment mono-, as shown in Figures 1 to 4.Be provided with the through hole 7 that runs through both in the inclusion portion of bolt 1 and sleeve 5, the hole inwall of sleeve 5 is provided with spiral shell seat 71, for screwing togather with the front end of lock-screw 2.Lock-screw 2 is fastened on pushing block 6 by groove 21, and interior rotatable at pushing block 6, lock-screw 2 is relative fixing with the position of pushing block 6.Be provided with second locating surface 13 a little more than bolt side in top end to the through hole of bolt 1, thereby screw togather the positive stop lug boss 12 that forms step on the through hole of perforating position at lock-screw 2, and establish one first locating surface 51 in sleeve 5 inside, such structure, when mounted, only need to aim at the second locating surface on bolt 1 by the first locating surface of sleeve 5, can pack latch assembly 3 into bolt 1, without the orientation of adjusting bolt, install more convenient.
When use, first the sleeve of latch assembly 35 is inserted in body 4, in the through hole 7 of the lock-screw 2 precession sleeves 5 in pushing block, slightly outstanding through hole 7 inner surfaces; Again bolt 1 is inserted in sleeve 5, after lock-screw 2 is encountered the positive stop lug boss 12 on bolt 1, stops; Rotational lock screw 2, make in its through hole 7 that screws in bolt 1, lock-screw 2 is fixed together sleeve 5 and bolt 1, and pushing block 6 is driven and together moves to sleeve 5, until the wedge shape guiding surface 61 on pushing block contacts with the wedge shape guiding surface 41 on body; Along with lock-screw 2 continues to screw in, drive pushing block 6 is continued to move upward, fix because of the vertical direction position of bolt 1, sleeve 5, body 4, force body 4 to move along inclined-plane occurred level, further advance to body of wall, thereby play fastening effect.
When dismounting, reverse rotation lock-screw, is screwed out spiral shell seat, just can realize dismounting.
Embodiment bis-, as shown in Fig. 5 to Fig. 8, is with the difference of embodiment mono-: spiral shell seat 71 is located at the hole inwall of bolt 1, in the surface of bolt 1 part of sleeve 5 inside, the second locating surface 11 matching with the first locating surface of sleeve 5 inside is set at inclusion; And be provided with back-moving spring 8 between sleeve 5 and pushing block 6, and in the time removing, can make lock-screw 2 leave after spiral shell seat 71, screw 2 end automatic trips are from the spiral shell seat 71 screw thread sections of rising; Positive stop lug boss 12 is positioned on the spiral shell seat of bolt; On sleeve, do not establish the first locating surface, also do not establish the second locating surface on bolt, such structure when mounted, need to be adjusted the orientation of bolt, make lock-screw aim at spiral shell seat, but manufacture craft is simpler, and fitting operation is convenient equally.All the other structures and assembling principle are with embodiment mono-.
The utility model can establish in the inclusion portion of bolt and sleeve the through hole that runs through both, can be also blind hole, while only needing to ensure that lock-screw and spiral shell seat screw togather, can have enough stroke spaces.Its effect is equal to.
Although specifically show and introduced the utility model in conjunction with preferred embodiment; but those skilled in the art should be understood that; not departing from the spirit and scope of the present utility model that appended claims limits; in the form and details the utility model is made a variety of changes, be protection domain of the present utility model.
