Detailed description of the invention
Fig. 1 is the top view of the preferred embodiment in the utility model；
Fig. 2 is the sectional view of the preferred embodiment in the utility model.
Specific embodiment
This case is described in further detail with reference to the accompanying drawings and detailed description.
With reference to Fig. 1-2, a kind of horizontal connected device fixed for backbone, comprising: above horizontal to connect hook 1, lower horizontal even hook 2 and be used for
By upper horizontal even hook 1 and the fixed nut 3 of lower horizontal even hook 2, bolt 4；
The upper horizontal even hook 1, lower horizontal even hook 2 respectively include a waling stripe 11,21, and are connected to the level 11,21
The flexible connector 12,22 of connecting rod one end；The other end of the upper horizontal even waling stripe 11 of hook 1 runs through along its thickness direction
One connecting hole is set；
The bolt 4 is along the direction parallel with the waling stripe 11,21 through one relief hole of setting；The lower horizontal company
It is fixed that the waling stripe 21 of hook 2 passes through the relief hole and bolt 4, the bolt 4 pass through after the connecting hole with the nut 3
It is fixedly connected；Therefore, bolt 4 has been fixedly connected with horizontal even hook 1, lower horizontal even hook 2 simultaneously, so that upper horizontal even hook 1, lower horizontal even hook 2
It is kept fixed.
For the even connective stability between hook 2 and bolt 4 horizontal under guaranteeing, so that lower horizontal even hook 2 will not be loose from bolt 4
It is de-.The waling stripe 21 of the lower horizontal even hook 2 is far from one end of flexible connector 22, in its end face along the length of waling stripe
Direction is recessed a concave hole 23；After the concave hole 23 and an expansion piece punching press, the outer wall of concave hole 23 along radial direction to
Outer expansion forms a circle flange, and the width of the flange is greater than the diameter of the relief hole.
Therefore, the waling stripe 21 of lower horizontal even hook 2 is first passed through into relief hole and bolt 4 is fixed, then is internal by expansion piece
Shrinkage pool 23 carries out punching press, generates the flange, since the width of flange is greater than the diameter of relief hole, in the position-limiting action of flange
Under, it would not fall off and separate between bolt 4 and lower horizontal even hook 2.
Further, in order to guarantee the upper horizontal even connective stability between hook 1 and bolt 4, i.e., between bolt 4 and nut 3
Connective stability, in the part that the bolt 4 is connect with nut 3, in the terminal surface of bolt 4 and the terminal surface of 3 through-hole of nut
It is squeezed by extrusion, so that the terminal surface of the bolt 4 is connected with the terminal surface of 3 through-hole of nut by being press-connected part 41
It connects.The part 41 that is press-connected makes bolt 4 and nut 3 not to relatively rotate after fixation, and bolt 4 and nut 3 are not yet
It can get loose.
Further, the part 41 that is press-connected is 4, is spaced each other 90 ° of angles.The quantity for being press-connected part 41 can also
With more or less, the simple replacement of the present embodiment is belonged to, is repeated no more.
The flexible connector 12,22 includes a threaded hole 121,221 and two clamping limbs 122,222；Two clampings
Armful clip space for clamping horizontal connecting bar is surrounded out between arm 122,222；The described one end of clamping limb 122,222 far from armful clip space is
A part of the inner arm of the threaded hole 121,221；One screw is fixedly connected with the threaded hole 121,221, adjusts the spiral shell
Position of the silk in threaded hole 121,221 changes the size for embracing clip space.
In order to allow embrace a clip space be it is elastic, size can change, the clamping limb as the position of screw is different
122, there are between 222 a linear grooves 123,223, be connected to the threaded hole 121,221.
The above descriptions are merely preferred embodiments of the present invention, not makees to the technical scope of the utility model
Any restrictions, the present embodiment are intended to illustrate the idea of the utility model and working principle, therefore all skills according to the utility model
The subtle modifications, equivalent variations and modifications of art essence made to above embodiments any shape and structure are still fallen within practical
The range of new technique scheme.
