Description
Technical field
The utility model belongs to a kind of fixing device, specifically, relates in particular to a kind of without screw blast cap fixing device.
Background technique
Wind energy is one of the most promising current novel energy, is inexhaustible, clean, pollution-free, reproducible green energy resource.In recent years, under the vigorously advocating of country, wind-driven generator industry emerges rapidly.The blast cap of traditional wind generally adopts screw and fan blade to be fastenedly connected, screw hole is offered in fan blade and blast cap many places, certainly will affect its integrity, especially long-term under the environment of exposing to the weather, screw hole place easily produces crack, causes blast cap to come off or fan blade fracture of root phenomenon.
Summary of the invention
The utility model discloses a kind ofly without screw blast cap fixing device, easily cause blast cap to come off or the problem of fan blade fracture of root for solving traditional blast cap fan blade screw means of fixation.
The utility model is achieved through the following technical solutions:
A kind of without screw blast cap fixing device, comprise blast cap and some fan blades, described every fan blade root is equipped with fan blade buckle, fan blade buckle is the circular arc bar that is provided with U-shaped groove, described blast cap connecting end is provided with blast cap buckle, blast cap buckle is the circular arc bar that is provided with U-shaped projection, corresponding being connected of U-shaped projection of the U-shaped groove of fan blade buckle and blast cap buckle.
Described fan blade buckle and fan blade root adopt mould to form an entirety, and blast cap buckle and blast cap connecting end adopt mould to form an entirety.
Compared with prior art, the beneficial effects of the utility model are:
The utility model utilizes fan blade buckle to be fixedly connected with blast cap buckle corresponding matching, simple in structure, easy installation and removal, without adopting fastened by screw, thoroughly solve that traditional blast cap easily comes off, the problem of fan blade root easy-rupturing, can be widely used in wind power generation field.
Brief description of the drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model cap structure schematic diagram;
Fig. 3 is the utility model blade structure schematic diagram;
Fig. 4 is fan blade buckle and blast cap buckle corresponding matching schematic diagram.
In figure: 1. fan blade; 2. fan blade buckle; 3. blast cap; 4. blast cap buckle.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further illustrated:
A kind of without screw blast cap fixing device, comprise blast cap and some fan blades, described every fan blade 1 root is equipped with fan blade buckle 2, fan blade buckle 2 is for being provided with the circular arc bar of U-shaped groove, described blast cap 3 connecting ends are provided with blast cap buckle 4, blast cap buckle 4 is for being provided with the circular arc bar of U-shaped projection, corresponding being connected of U-shaped projection of the U-shaped groove of fan blade buckle 2 and blast cap buckle 4.
Described fan blade buckle 2 adopts mould to form an entirety with fan blade 1 root, and blast cap buckle 4 adopts mould to form an entirety with blast cap 3 connecting ends.
Taking 5 fan blade quantity as example, every fan blade root is provided with fan blade buckle, and correspondingly the even rule of blast cap connecting end is provided with 5 blast cap buckles corresponding with fan blade buckle.Obviously, self-assembling formation breach between adjacent blast cap buckle, forms breach between adjacent fan blade buckle too.Need to fix time, blast cap buckle is aimed to fan blade buckle, and namely the breach between fan blade buckle is corresponding with the breach between blast cap buckle, slightly firmly presses, and rotate slightly blast cap 3, gap position between breach and the blast cap buckle between fan blade buckle is staggered, is fastenedly connected guaranteeing, in like manner, if take off blast cap, rotate gently blast cap, the breach between blast cap buckle is alignd with the gap position between fan blade buckle, then slightly firmly drag lower blast cap.Whole process, without adopting fastened by screw, has thoroughly solved traditional blast cap and has easily come off, the problem of fan blade root easy-rupturing.
In sum, it is only preferred embodiment of the present utility model, not be used for limiting the scope that the utility model is implemented, all equalizations of doing according to the shape described in the utility model claim scope, structure, feature and spirit change and modify, and all should be included within the scope of claim of the present utility model.
