Abstract

The utility model relates to the rain tool technology field, in particular to an umbrella framework of the non-blocking device. The technology scheme is: one end of the upper fulcrum is hinged on the fulcrum and the other end of the fulcrum is hinged on the middle fulcrum, and the two ends of the side upper fulcrum are respectively hinged on one end of the middle fulcrum and the upper fulcrum. One end of the middle fulcrum is hinged on one end of the lower fulcrum while one end of the lower fulcrum is hinged on the tail fulcrum. The two ends of the side lower fulcrum are respectively hinged on the middle fulcrum and the tail fulcrum. Due to the application of the device, the lower bracket and the upper bracket are pressed together by using the branch force produced by the fulcrum, thus realizing the buckling of the umbrella tools. In this way, the utility model does not need to process the lock-tongue and provide a locking hole on the pillar, thus not only guaranteeing the strength of the pillar but also simplifying the working procedure and reducing the product cost.

Description

The umbrella framework of no holding device

Technical field:

The utility model relates to the rain gear technical field, refers in particular to a kind of umbrella framework that does not have holding device.

Background technology:

Because folding parachute kit can fold placement, and is easy to carry, thereby current use is more.It is also light with it, practical characteristics is subjected to people's favor deeply.The holding device of the multi-fold umbrella that uses on the market generally all is to adopt to offer a lockhole on pole at present, and elastic lock tongue stretches out from lockhole, utilizes elastic lock tongue to support lower carriage, reaches the open purpose of parachute kit.This structure exists following shortcoming: at first, what pole was generally adopted at present is aluminium, owing to will on pole, offer lockhole, so the intensity of pole will weaken, in order to remedy this point, adopt pole made of iron to substitute one section aluminum pole, though guaranteed the intensity of pole like this, but iron is corroded by malaria easily, is etched easily especially in the place of offering lockhole especially.Secondly, the processing dead bolt reaches offers a lockhole on pole, operation is increased, thereby also increase to some extent of labor cost, thereby causes the rising of entire product expense.Goal of the invention:

The purpose of this utility model just is to provide a kind of support self tension force that utilizes with parachute kit umbrella framework fixing, that need not holding device.

Summary of the invention:

The utility model is achieved by the following technical solution: an end of upper ramus is hinged on the fulcra, and the other end of fulcra is hinged on the middle ramus, and the two ends of secondary upper ramus are hinged on respectively on the end and upper ramus of middle ramus.One end of middle ramus is hinged on the end of lower support rib, and the other end of lower support rib joins on the tail fulcra, and the two ends of secondary lower support rib are hinged on respectively on middle ramus, the tail fulcra.One end of rib is fixed on the fulcra, and the other end is fixed on an end of lower support rib.

After adopting this structure, when parachute kit opens fully, fulcra will produce a component that makes progress to lower carriage, utilize this component that lower carriage and upper bracket are pressed together, thereby realize the fastening of parachute kit.So need not to process dead bolt and on pole, offer lockhole, not only guaranteed the intensity of pole, and operation is simplified, reduce the cost of product.

Description of drawings:

Below in conjunction with accompanying drawing the utility model is further described:

Fig. 1 is the utility model structure chart when not opening fully;

Fig. 2 is the utility model structure chart when opening fully;

Fig. 3 is the utility model force analysis figure when opening fully.

See accompanying drawing 1,2, the utility model comprises: pole 1, upper bracket 2, lower carriage 3 And the parachute kit fulcra, upper bracket 2 is fixed on an end of pole 1, and lower carriage 2 is socketed in pole On 1, an end of upper ramus 4 is hinged on the upper bracket 2, and an end of fulcra 5 is hinged on down On the support 3. The other end of upper ramus 4 is hinged on the fulcra 5, the other end of fulcra 5 hinge Be connected on the middle ramus 6, the two ends of secondary upper ramus 41 be hinged on respectively middle ramus 6 an end and On the upper ramus 4. One end of middle ramus 6 is hinged on the end of lower support rib 7, lower support rib 7 Other end handing-over on tail fulcra 8, the two ends of secondary lower support rib 71 are hinged on respectively middle ramus 6, on the tail fulcra 8. One end of rib 61 is fixed on the fulcra 5, and the other end is fixed on down One end of fulcra 7.

See accompanying drawing 3, O, A, B, C, D, E are six hinged points of the present utility model, its Middle conductor EC, CD, DB length overall are greater than the length of line segment OB.

The specific embodiment:

When using the utility model, open parachute kit, promoting lower carriage 3 up moves, lower carriage 3 drives fulcra 5 work simultaneously, fulcra 5 promote upper ramus 4 and outwards open, and drive other fulcra successively, these skeletons support umbrella cover together, on lower carriage 3, move on to top, promptly be close to below the upper bracket 2, at this moment as shown in Figure 2: upper ramus 4, secondary upper ramus 41, and middle ramus 6 is almost on same straight line, and because EC, CD, the length overall of DB is greater than the length of OB, so fulcra 5 will be slightly downward-sloping away from an end of lower carriage 3, simultaneously because the elastic force of skeleton self makes 5 pairs of lower carriages of fulcra 3 produce a pressure, as shown in Figure 3: pressure F will produce a component f who makes progress, below the effect lower carriage 3 of power f was pressed in upper bracket 2, parachute kit was opened and is finished like this, and is locked.When not in use, spur lower carriage 3 downwards, when pulling force during greater than power f, the poised state of parachute kit is broken, and parachute kit will be drawn in.So need not to process dead bolt and on pole, offer lockhole, not only guaranteed the intensity of pole, and operation is simplified, reduce the cost of product.
