Abstract
The utility model discloses a screw fixing structure of a plastic bracket. The screw fixing structure comprises a bracket body (1) and a mounting hole (2) for fixing the bracket, and is characterized in that a metal sleeve (3) is arranged in the mounting hole (2), wherein the metal sleeve (3) is in interference fit with the mounting hole (2). According to the screw fixing structure, the problems of high probability of cracking and high product rejection rate of the plastic bracket under the condition of higher bearing capacity requirement of the plastic bracket are solved. Meanwhile, the strength of the plastic bracket is greatly improved, the cost can be saved, the product rejection rate is reduced, and the requirements for actual production can be met better. The screw fixing structure can be widely applied to the field of plastic bracket fixation.
Description
Technical field
The utility model relates to a kind of fixed structure, especially relates to a kind of plastic stent screw fixed structure.
Background technique
Various plastic stents adopt the fixing mode of screw, and right and wrong are usually seen in real work, and require when larger when the power of the working of plastics carrying of being fixed, selecting also of screw specification can correspondingly strengthen, screw lock power improves, this moment fixture the also corresponding increase of power of carrying of screw via structure, but often the structural strength of plastic materials is difficult to meet the demands, and the phenomenon of structure damage and crack occurs easily, causes product rejection rate higher.
The model utility content
The purpose of this utility model provides a kind of plastic stent screw fixed structure, solution easy damage and crack of plastic stent in the larger situation of plastic stent requirement for bearing capacity, the problem that product rejection rate is higher.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of plastic stent screw fixed structure, comprise rack body, be used for the mounting hole of fixed support body, also be included in and be provided with a metallic sheath, described metallic sheath and mounting hole interference fit in the mounting hole.In order to better meet the demand of stress, described metallic sheath is copper sheathing.
In order conveniently to press-fit, described metallic sheath end face is provided with the oblique angle that makes things convenient for pressing, and there is equally distributed straight burr its outer ring.
In order better to reach the assembling effect, the endoporus of described metallic sheath is unthreaded hole or tapped hole.
The beneficial effects of the utility model: in the plastic stent mounting hole, set up a metallic sheath, can solve original plastic stent stressed large flimsy problem when installation is fastening, adopt copper sheathing intensity higher, adopt oblique angle and straight burr conveniently to press-fit, simultaneously for the use of the screw that satisfies different size, the metallic sheath endoporus adopts unthreaded hole and tapped hole dual mode; The problem of the easy damage and crack of plastic stent that the conventional method that solved the utility model causes so that plastic stent intensity significantly improves, can be saved cost simultaneously, and product rejection rate reduces, and can better satisfy the needs of actual production.
Below with reference to drawings and Examples, the utility model is described in detail.
Description of drawings
Fig. 1 is perspective exploded view of the present utility model.
Fig. 2 is the plan view with the straight burr metallic sheath described in the utility model.
Among the figure: 1. rack body; 2. mounting hole; 3. metallic sheath; 4. oblique angle.
Embodiment
Shown in Fig. 1 to 2, a kind of plastic stent screw fixed structure comprises rack body 1, is used for the mounting hole 2 of fixed support body 1, also is included in and is provided with a metallic sheath 3 in the mounting hole 2, metallic sheath 3 and mounting hole 2 interference fit.In order to better meet the demand of stress, described metallic sheath 3 is copper sheathing.
In order conveniently to press-fit, described metallic sheath 3 is provided with the oblique angle that makes things convenient for pressing, and there is equally distributed straight burr its outer ring.In order better to reach the assembling effect, the endoporus of described metallic sheath 3 is unthreaded hole.
Owing to adopted plastic stent screw fixed structure, needs plastic stent is carried out screw fixing before, metallic sheath 3 is press-fited in the mounting hole 2 of rack body 1, after screw passes the locking of metallic sheath via hole, can not be damaged to plastic stent; The problem of the easy damage and crack of plastic stent that the conventional method that solved the utility model causes so that plastic stent intensity significantly improves, has been saved cost, simultaneously so that product rejection rate be reduced.
Described metallic sheath 3 endoporus are tapped hole, the other the same as in Example 1.
