Abstract
The utility model discloses a kind of without screw fixing device, by fixed plate, main fixing rod and sliding bar composition, described fixed plate is provided with sphere plate hole, main fixing rod head is spherical and has default sliding-groove, use of the present utility model, first fixed plate is placed on base material, holed on base material by the plate hole of fixed plate, main fixing rod is inserted boring, and the default sliding-groove of sliding bar along main fixing rod is filled in, the expansion of main fixing rod is combined closely with base material, main fixing rod head expansion is simultaneously combined closely with sheet material sphere plate hole, base material, fixed plate, main fixing rod and sliding bar form the entirety of a rock-steady structure, without screw fixing device after tightening, self-strength exceedes the common of same diameter threaded screw, fixed object is firm, tight without screw fixing device.
Description
Technical field
The utility model relates to fixing device, is specifically related to a kind of without screw fixing device.
Background technique
Fixing device common at present, it relies on screw is threaded into object, and playing to connect needs fixing object.The deficiency of this means of fixation is, the screw thread of screw only provides the effect of fixed object, but is reduction of the intensity of screw self, makes screw easily bending or fracture, causes solid failure.
Model utility content
The purpose of this utility model is for the deficiencies in the prior art, provides a kind of fixing device after tightening, and self-strength exceedes the common of same diameter threaded screw, and fixed object is firm in, tight screw fixing device.
The technological scheme realizing the employing of the utility model object is: be made up of fixed plate, main fixing rod and sliding bar without screw fixing device, described fixed plate is provided with sphere plate hole, and main fixing rod head is spherical and has default sliding-groove.
Use of the present utility model, first fixed plate is placed on base material, holed on base material by the plate hole of fixed plate, main fixing rod is inserted boring, and the default sliding-groove of sliding bar along main fixing rod is filled in, the expansion of main fixing rod is combined closely with base material, and main fixing rod head expansion is simultaneously combined closely with sheet material sphere plate hole, and base material, fixed plate, main fixing rod and sliding bar form the entirety of a rock-steady structure.
Further technological scheme is:
Owing to expanding in the spherical sphere plate hole on fixed plate of main fixing rod head, the restriction being subject to plate hole cannot be exited, and main fixing rod other parts, in base material internal expansion, also cannot exit.
The utility model is the improvement to existing screw fixing device, be characterized in that main fixing rod is by forming tight rock-steady structure with coordinating of sliding bar with the spherical plate hole on fixed plate, main fixing rod expands and expands in base material, base material, fixed plate, main fixing rod and sliding bar form the entirety of a rock-steady structure, realize fixation.
This device is particularly suitable for surgery wound operation.
The technological scheme of model utility is further illustrated below in conjunction with accompanying drawing.
Accompanying drawing explanation
Fig. 1 structural representation of the present utility model
Fig. 2 using effect figure of the present utility model
Embodiment
See Fig. 1, be made up of, fixed plate 3 is provided with sphere plate hole without screw fixing device main fixing rod 1, sliding bar 2 and fixed plate 3, main fixing rod 1 head is spherical and has default sliding-groove.
Using effect of the present utility model as shown in Figure 2, main fixing rod 1 is inserted the sphere plate hole of fixed plate 3, when the default sliding-groove of sliding bar 2 along main fixing rod 1 pushes, main fixing rod 1 head is that spherical expansion and fixed plate 3 are provided with sphere plate hole and combine closely, main fixing rod 1 body expand into inverted cone and base material 4 is combined closely, and reaches the effect that fixed plate 3 is fixing with base material 4.
