Abstract
The utility model relates to an umbrella frame medium dish fixer which primarily adopts a mode of plastic injection molding on an umbrella frame made of fiber glass to make a medium dish integrally formed in a proper position on the umbrella frame, and then a drift bolt is used to penetrate through the umbrella frame and the medium dish through the side of the medium dish and is fixed in the medium dish, providing a positioning effect with admirable stability.
Description
The utility model relates to butterfly fixture in a kind of umbrella frame, mainly is to adopt injection molding mode to be arranged on the umbrella frame appropriate location butterfly in plastic, passes butterfly and umbrella frame in this with a drift bolt again, uses the locating effect that provides firm.
General parachute kit, its umbrella frame is to be material with the metal mostly, but metal material produces oxidation in use for some time, especially the parachute kit after drenching, in time it is dried if fail, will inevitably cause umbrella frame and middle butterfly riveted place to produce corrosion or come off, can form structural dead angle, and be easy to damage.
In order to solve the problem that umbrella frame that the aforementioned metal material makes can produce oxidation corrosion or come off in wet environment, adopt glass fibre to make umbrella frame, the glass fibre material itself has better elastic, also do not have simultaneously the problem of oxidation corrosion, the weight of its material itself is lighter simultaneously, has practicality really.
Yet when adopting the glass fibre material to make umbrella frame, can't be drilled with it on and bore a hole so that butterfly in the riveted and fixed.Thereby at the beginning of this type of glass fibre umbrella frame of exploitation, adopt structure as shown in Figure 3, middle butterfly 90 is made the structure with register hole 91, butterfly 90 sides are provided with the pivoted hole 92 that articulates fulcra in this simultaneously, register hole 91 sides of butterfly 90 are provided with the side perforation 93 that penetrates in this register hole 91 in this in addition, when assembling, be that the register hole 91 of butterfly 90 is set on the umbrella frame 95 in will being somebody's turn to do, after cover is bonded to the location, manually to carry out a glue by side perforation 93 places, the operation of mat point glue is fixed as one umbrella frame 95 and middle butterfly 90 again; But the fixed effect of the middle butterfly 90 of this structure is not good, butterfly 90 during the operation of some glue often can't be fixed really, so promptly can on umbrella frame 95, produce displacement after using a period of time, obviously adopt this structure that stable locating effect can't be provided, manually carry out fit simultaneously and put the glue operation influencing integral production efficient.
In addition, existing structure as shown in Figure 2, be directly to adopt injection molding mode to be combined on the umbrella frame 75 that glass fibre makes butterfly in plastic 70, butterfly 70 sides also are provided with the pivoted hole 71 that articulates fulcra in this, this structure is learnt through analysis, a breach 76 has been cut by production firm on this umbrella frame 75, to structural analysis as can be known, this breach 76 mainly is in order to allow the location that butterfly 70 can be firm in the injection molding plastics system, because the smooth in appearance of glass fibre material own, simple with 70 injection mouldings of butterfly in the plastics system thereon, can't provide suitable locating effect in fact, so these umbrella frame 75 structures are provided with a breach 76, can keep the location so that annotate for the middle butterfly 70 of penetrating moulding;
Yet find in reality test back, butterfly 70 has splendid locating effect in use really in aforesaid, but owing to cut a breach 76 on the umbrella frame 75, thereby the glass fibre material of this position is blocked, so can be in being provided with the position of butterfly 70 form the structure of whole umbrella frame 75 most fragiles, because the diameter of the umbrella frame 75 that is adopted is all selected through suitable test, and for butterfly 70 stable position effects in this are provided, have no alternative but cut and set out a breach 76, thereby undermine its intensity, after the user uses a period of time, or when meeting with high wind and blowing, promptly can cause losing of this umbrella frame 75, and parachute kit is scrapped, this promptly is butterfly 70 and the bad critical defect that causes of umbrella frame 75 structural designs in this type of.
Primary and foremost purpose of the present utility model is to provide butterfly fixed structure in a kind of umbrella frame of improvement, it mainly is the mode that on the umbrella frame of glass fibre system, adopts injection-moulding plastic, middle butterfly is shaped on the umbrella frame appropriate location, then pass umbrella frame and middle butterfly with a drift bolt by middle butterfly side again, and be fixed in the middle butterfly, use the locating effect that provides stable.
The butterfly fixture is a butterfly fixed structure in the plastics system on a kind of umbrella frame that is arranged at glass fibre system in the umbrella frame that the utility model provides, and its characteristics are:
Middle butterfly is arranged on the umbrella frame appropriate location with injection molding, and passes umbrella frame and middle butterfly by middle butterfly side, be fixed in the middle butterfly with a drift bolt.
Fig. 1 is a butterfly fixed structure schematic diagram in the umbrella frame of the present utility model.
The structural representation that Fig. 2 matches with the middle butterfly of injection-moulding plastic for existing mat umbrella frame breach.
Fig. 3 is the middle butterfly structural upright decomposing schematic representation of another existing umbrella frame counterpart register hole.
As shown in Figure 1, umbrella frame 10 of the present utility model and middle butterfly 20 fixed structures, the utility model is middle butterfly 20 structures on a kind of umbrella frame 10 that applies to glass fibre system, should middle butterfly 20 be to adopt the mode of injection-moulding plastic to be shaped on umbrella frame 10 appropriate locations, and with a drift bolt 30 by middle butterfly 20 sides pass umbrella frame 10 and in butterfly 20, and be fixed in the middle butterfly 20, use the locating effect that provides stable.
Figure as can be seen thus, the utility model is directly to adopt injection moldings to be integrally formed at appropriate location on the umbrella frame 10 butterfly in plastic 20, need not again manually to carry out suit and some glue, process velocity is very fast, can reduce production costs, in addition, butterfly 20 and umbrella frame 10 during the utility model passes with drift bolt 30, with middle butterfly 20 firm being positioned on the umbrella frame 10, its locating effect is splendid, and when drift bolt 30 passes umbrella frame 10, can pass between the slit by glass fibre, the glass fiber material quantity of being blocked is very limited, and for the structural strength of whole umbrella frame 10, and do not have excessive influence, enough intensity can be provided, have now on umbrella frame, cut establish breach provide in the fixing structure of butterfly more excellent.
By above explanation as can be known, the utility model is integrally formed at middle butterfly 20 on the umbrella frame 10 that glass fibre makes in injection molding mode, and butterfly 20 and umbrella frame are 10 in being arranged in a drift bolt 30 again, reach the effect of strong fix, it is easy to process and structure is strong, has splendid locating effect.
