The jacket is clamped and fixed on the middle supporting rib. A through hole penetrated by the elastic draw rod is formed between the jacket and the middle supporting rib. After the utility model adopts such structure, the jacket is fixed on the middle supporting rib in a clamping way so the position of the jacket is fixed, when the utility model is used, uneven elasticity can not occur, and the umbrella can be smoothly and quickly folded.
Description
Technical field:
The utility model relates to the parachute kit technical field, refers in particular to a kind of umbrella rib structure of multi-fold umbrella.
Background technology:
Parachute kit is articles for use indispensable in people's daily life as the instrument of people's sun-shading rain-proof.And the multi-fold umbrella in the parachute kit, because it has and can fold placement, advantage such as easy to carry and obtain liking of numerous users.Common multi-fold umbrella mainly comprises a middle rod as main support, is installed in upper and lower nest, umbrella rib structure that is connected with up-down runner on the middle rod and the umbrella cover that is covered in the umbrella rib structure surface.Include two ends in the umbrella rib structure and be articulated in middle ramus between main fulcra and the outer fulcra, be provided with a pull bar side by side with middle ramus, these pull bar two ends are hinged with main fulcra and outer fulcra respectively.Because main fulcra can't directly drive outer fulcra, so need make it can realize folding by the outer fulcra of pull bar pulling.In actual use, realize folding for umbrella frame can be more prone to, adopt elastomeric material to make on pull bar, and be arranged with a collar on middle ramus, pull bar wears in the collar.When in the process that folds, under collar restriction, elastic draw bar will produce certain elastic deformation like this, and the elastic force that himself produce this moment folds more favourable outer fulcra.The currently used collar is a plastic cement collar, it directly is placed on the middle ramus, the problem that this mode exists is exactly, the position of this collar can't be fixed, and it can slide on middle ramus, causes in the use, because the variation of cover ring position, the pulling force that the elastic draw bar two ends produce is inhomogeneous, causes outer fulcra to fold difficulty, makes troubles to the user.
Summary of the invention:
The purpose of this utility model is the deficiency at present product, provides a kind of structure firm, folds the umbrella rib structure of multi-fold umbrella easily and efficiently.
For achieving the above object, the utility model is achieved through the following technical solutions: it comprises that two ends are articulated in the middle ramus between main fulcra and the outer fulcra, the elastic draw bar that is positioned at the chuck on the middle ramus and passes chuck, wherein, the two ends of elastic draw bar are hinged with main fulcra and outer fulcra respectively, the chuck double team is fixed on the middle ramus, and is formed with the through hole that passes for the elasticity pull bar between chuck and the middle ramus.
Above-mentioned middle ramus comprises fine bone of a carbon and the connecting portion that is fixed in the fine bone of carbon two ends, and forms " M " shape groove along the fine bone upper surface of carbon, and its lower surface inwardly forms a depressed part.
Above-mentioned chuck double team is fixed on the fine bone of carbon of middle ramus, and the one side that forms " M " shape groove on the fine bone of the relative carbon of chuck is to forming a protuberance, and elastic draw bar is passed by the space that forms between groove and the protuberance.
After the utility model adopted such structure, chuck adopted the mode of double team to be fixed on the middle ramus, made the fixed-site of chuck, guaranteed in use can not occur the situation of elastic force inequality, and it is smooth and easy, quick to guarantee that parachute kit folds.In addition, middle ramus of the present utility model adopts the structure of approximate " M " shape of cross section, not only can improve its intensity, and formed groove is convenient to elastic draw bar and is passed.At last, the groove of relative middle ramus simultaneously forms a protuberance on the chuck, and this protuberance also is to be convenient to elastic draw bar better pass, and guarantees that in use pull bar has enough activities, and it is smooth and easy to guarantee that parachute kit folds.
Description of drawings:
Fig. 1 is a front view of the present utility model;
Fig. 2 is the front view of the utility model middle ramus;
Fig. 3 be among Fig. 1 A-A to profile;
Fig. 4 does not install preceding stereogram for the utility model chuck.
The specific embodiment:
See Fig. 1～4, the related umbrella rib structure of the utility model comprises: two ends are articulated in middle ramus 2, chuck 4 and the elastic draw bar 5 between main fulcra 1 and the outer fulcra 3.Wherein chuck 4 is placed on the middle ramus 2, and chuck 4 double teams are fixed on the middle ramus 2.Elastic draw bar 5 wears chuck 4, and its two ends are hinged with main fulcra 1 and outer fulcra 3 respectively.
Above-mentioned middle ramus 2 comprises fine bone 21 of a carbon and the connecting portion 22,23 that is fixed in the fine bone of carbon 21 two ends, and the fine bone 21 of described carbon is the umbrella frames that adopt the charcoal fibrous material to make, and it not only has advantages of high strength, and has lightweight advantage.Adopt this material to make middle ramus, under the prerequisite that does not reduce parachute kit intensity, can further reduce the weight of parachute kit.The upper surface of the fine bone 21 of carbon forms " M " shape groove 211, and its lower surface inwardly forms a depressed part 212.That is, the cross section of the fine bone 21 of carbon is approximate " M " shape.Adopt this shape, formed " M " shape groove 211 is convenient to elastic draw bar 5 and is passed on the fine bone 21 of carbon, and adopts this shape can further strengthen the intensity of the fine bone 21 of carbon.
Chuck 4 double teams are fixed on the fine bone 21 of carbon of middle ramus 2, and the one side of formation " M " shape groove 211 is formed with a protuberance 41 on the fine bone 21 of chuck 4 relative carbon, and elastic draw bar 5 is passed by the space that forms between " M " shape groove 211 and the protuberance 41.The junction of chuck 4 is in the depressed part 212 of fine bone 21 lower surfaces of carbon, and the junction surface of chuck 4 can be to depressed part 212 bendings, with the fine bone 21 of better clamping carbon like this.Protuberance 41 on the chuck 4 also is better to pass for the ease of elastic draw bar 5, and its cooperation " M " shape groove 211 guarantees that in use elastic draw bar 5 has enough activity spaces, and it is smooth and easy to guarantee that parachute kit folds.
When the utility model is installed, can install main fulcra 1, middle ramus 2 and outer fulcra 3 earlier, then chuck 4 double teams are fixed on the fine bone 21 of carbon of middle ramus 2, the elastic draw bar 5 that then two ends is formed with crotch is passed by the space between the fine bone 21 of chuck 4 and carbon, and the crotch portion at elastic draw bar 5 two ends and main fulcra 1 are hinged together with outer fulcra 3 gets final product at last.Better pass space between the fine bone 21 of chuck 4 and carbon for the ease of the crotch portion at elastic draw bar 5 two ends, offer breach 411,412 on the surface that constitutes chuck 4 protuberances 41.Like this, just can make the less crotch of radius pass chuck 4 smoothly.
In sum, after the utility model adopts such structure, make the fixed-site of chuck 4, guarantee in use can not occur the situation of elastic draw bar 5 elastic force inequalities, it is smooth and easy, quick to guarantee that parachute kit folds.
The embodiment of the above is preferred embodiment of the present utility model only, is not to limit practical range of the present utility model with this, so the equivalence that all shapes according to the utility model, structure and principle are done changes, all should be covered by in the protection domain of the present utility model.
