Specific embodiment
Embodiment referring to figs. 1 to Fig. 3 length-adjustable bolts a kind of to the utility model is described further.
A kind of length-adjustable bolt, including bolt head, reinforcing polished rod and screw rod 8, the circumference of the bolt head
The groove that oriented bolt head inner side extends is opened up on wall, the control-rod 1 that groove is stretched out in part is provided with the groove, it is described
Spring 2 is provided between one end of control-rod 1 and the bottom surface of groove, oriented reinforcing polished rod direction is opened up on the side wall of the groove
Connecting rod 6 is provided with the holding tank 4 of extension, institute's holding tank 4, the connecting rod 6 is hinged with control-rod 1, the side wall of the holding tank 4
On be provided with the pole 5 being hinged with the middle part of connecting rod 6, on the connecting rod 6 correspondence pole 5 lower section be provided with several limit convexes
7 are played, described one end for reinforcing polished rod offers the telescopic chute 12 coordinated with screw rod 8, if being offered on the side wall of the holding tank 4
The dry hole clipping 3 coordinated with spacing preiection 7, offers the card coordinated with several spacing preiections 7 on the circumferential side wall of the screw rod 8
Groove 9.
Axis direction from the preferred groove of the present embodiment to bolt head extend, when the length for needing adjusting screw rod 8 when
Wait, it is only necessary to which, by lower control arm 1, spring 2 is compressed, control-rod 1 moves a segment distance along groove, drive and the side of control-rod 1
Connecting rod 6 that wall is hinged moves a segment distance, because the middle part of connecting rod 6 is hinged with the pole 5 on the side wall of holding tank 4, then connecting rod 6
The other end move backward a segment distance, the original state of the spacing preiection 7 in the present embodiment stretches into hole clipping 3, so limit
Position raised 7 drives removal hole clipping 3 by connecting rod 6, while spacing preiection 7 no longer coordinates positioning with the draw-in groove 9 on screw rod 8, so that can
To control the free raising and lowering in telescopic chute 12 of screw rod 8, adjustment length, while when 8 length of adjusting screw rod, unclamping
Control-rod 1, spring 2 is no longer influenced by extruding force and recovers deformation, and so when 8 length of adjusting screw rod, spacing preiection 7 can be received
Snapped in automatically in the draw-in groove 9 on screw rod 8 to the reseting elasticity of spring 2, realize being automatically positioned, whole process is without extra work
Tool operation, control is simple, easy to adjust and can be automatically positioned.
The screw thread coordinated with screw rod 8 is provided with the circumferential side wall of the preferred telescopic chute 12 of the present embodiment, by spiral shell
Bar 8 coordinates with the screw thread of telescopic chute 12, and screw rod 8 can be made to realize self-retaining in vertical direction, makes the in the vertical direction of screw rod 8
The relatively stable fixation in position, while spring 2 is no longer deformed upon by the gravity of screw rod 8, so as to improve the use of spring 2
Life-span.
Defining flange, one end of the screw rod 8 are provided with the circumferential side wall of the preferred telescopic chute 12 of the present embodiment
Gag lever post 10 is provided with, the other end of the correspondence connecting screw rod 8 of the gag lever post 10 is provided with the spacing heel coordinated with defining flange
11, the excessively rotation of screw rod 8 can be prevented and telescopic chute 12 is dropped out.
The preferred defining flange of the present embodiment is curved in vertical direction section, when screw rod 8 along with telescopic chute 12
It is lower dynamic up or out, because defining flange is curved in vertical direction section, then the power downward to defining flange of screw rod 8
Power vertically and laterally is resolved into by the cambered surface in the curved defining flange of vertical direction, will not be stuck, so that limit convex
Edge is gradually pressed into draw-in groove 9, so as to realize being automatically positioned for screw rod 8.
The preferred defining flange section in the horizontal direction of the present embodiment is square, so when spacing preiection 7 blocks
Enter when in draw-in groove 9, due to defining flange section in the horizontal direction be square so when turning on and screw rod 8 coordinate
When nut, screw rod 8 can be limited flange and block, and will not be rotated against with telescopic chute 12, such that it is able to taking for stabilization
Lower nut.
Spring 2 in the present embodiment can also be arranged on connecting rod 6 one end and holding tank 4 for being correspondingly arranged spacing preiection 7
Side wall between.
Overall controlling organization in the present embodiment can be symmetrical arranged in two groups, make the uniform force of whole bolt.
The above is only preferred embodiment of the present utility model, and protection domain of the present utility model is not limited merely to
Above-described embodiment, all technical schemes belonged under the utility model thinking belong to protection domain of the present utility model.Should refer to
Go out, for those skilled in the art, some improvement under the premise of the utility model principle is not departed from and
Retouching, these improvements and modifications also should be regarded as protection domain of the present utility model.
