Description
Technical Field
The utility model relates to the technical field of articles for daily use, especially, relate to a knapsack umbrella multi-fold rib's extension structure and knapsack umbrella thereof.
Background
Umbrella comprises umbrella face and umbrella support among the prior art, the umbrella support sets up and is used for supporting the umbrella face in the below of umbrella face, the length of the umbrella rib of the umbrella support of the umbrella of commonly used in the life all is the same and length equals, this just leads to the umbrella face to be circular, when the people takes the umbrella stick in the front side of health, drench the back of health very easily, when especially user's back is worn the knapsack, the umbrella face can't carry out effectual sheltering from to the knapsack, make the knapsack drenched by the rainwater. Therefore, a backpack umbrella is invented, which is specially used when a user wears a backpack on the back, the umbrella ribs of the backpack umbrella are composed of a plurality of common multi-fold umbrella ribs 100 and at least two lengthening umbrella ribs 200, the lengthened umbrella ribs are more than the adjacent common multi-fold umbrella ribs by one fold, if the common umbrella ribs are folded twice, the lengthened umbrella ribs are three-fold umbrella ribs, if the common umbrella ribs are three-fold (as shown in figure 1), the lengthened umbrella ribs are four-fold umbrella ribs (as shown in figure 2), and the like; the lengthened umbrella rib is mainly used for locally lengthening the umbrella cover so as to achieve the purpose of protecting the backpack which can be carried on the back of a user and shielding rain.
The umbrella ribs of the existing backpack umbrella, whether short (as shown in fig. 1) or lengthened (as shown in fig. 2 and fig. 3), are all common ones, and the structure of the common umbrella ribs at least comprises a first rib 301, a second rib 302 and a third rib 303 hinged from outside to inside in sequence, and a connecting rod 304, wherein adjacent ribs are hinged through a joint, the second rib 302 is hinged with a first joint 308 at a point a, the third rib 303 is hinged with a second joint 309 at a point b, the connecting rod 304 is hinged with the first joint 308 at a point c, and is hinged with the third rib 303 at a point d, and the distance between the hinge points b and d is basically equal to the distance between the hinge points a and c (within an allowable error range, within plus or minus 15 umm). Because the structural design of the common umbrella ribs is unreasonable, the problem that the lengthened umbrella ribs of the backpack umbrella are easy to turn upwards when the backpack umbrella is opened is easy to occur, and the backpack umbrella needs to be turned back to reset by hands after being turned upwards, so that the experience of a user is influenced. In addition, the umbrella cover corresponding to the lengthened umbrella ribs of the backpack umbrella can cause the lengthened umbrella cover to form a large upward-turning force when strong wind is encountered, and users with small strength can hardly grasp the unfolded umbrella under the condition.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a backpack umbrella and extension structure of many books ribs of backpack umbrella that extension rib is difficult to upturning when opening the umbrella, user's experience feels better and backpack umbrella thereof.
The second purpose of the utility model is to relieve the wind force of the umbrella cover of the lengthening part turning upwards when strong wind exists.
In order to realize the first purpose, the utility model adopts the following technical scheme:
the utility model provides a backpack umbrella is long structure of book rib more includes at least by outer to interior articulated first rib, second rib and third rib in proper order, and the connecting rod, the inner of first rib is equipped with first joint, and the outer end and the first joint of second rib articulate in first pin joint A, and the inner of second rib is equipped with the second joint, and the outer end and the second joint of third rib articulate in second pin joint B, the both ends of connecting rod articulate in third pin joint C, articulate in fourth pin joint D with third rib with first joint respectively, distance H between second pin joint B and the fourth pin joint D 2 Is greater than the distance H between the first hinge point A and the third hinge point C 1 。
To achieve the second object, an elastic member is provided at a part of the link.
As an improvement of the utility model, the elastic part is arranged at the two ends or the middle of the connecting rod.
As the improvement of the utility model, the elastic part is a tension spring or a rubber band.
As an improvement of the utility model, the connecting rod is a metal rod or a plastic rod.
As an improvement of the utility model, the outer end of the first umbrella rib is also provided with a bead tail.
As an improvement of the utility model, the bead tail is provided with a through hole.
The utility model discloses an another technical scheme is: the utility model provides a backpack umbrella, includes umbrella stick, umbrella stand and umbrella face, the umbrella stand sets up on the umbrella stick, the umbrella face sets up on the umbrella stand, the umbrella stand includes several array ribs, several array at least two sets of extension structure ribs that are in the rib, and are two sets of extension structure rib is one of the extension structure of foretell backpack umbrella multifold rib.
The utility model discloses because at least, include from outer to interior articulated first rib, second rib and third rib in proper order, and the connecting rod, the inner of first rib is equipped with the first joint, and the outer end and the first joint of second rib articulate in first pin joint A, and the inner of second rib is equipped with the second and connects, and the outer end and the second joint of third rib articulate in second pin joint B, the both ends of connecting rod articulate in third pin joint C, articulate in fourth pin joint D with third rib with first joint respectively, distance H between second pin joint B and the fourth pin joint D 2 Is larger than the distance H between the first hinge point A and the third hinge point C 1 The advantage of design like this lies in when the parachute-opening, and the connecting rod keeps the power of pulling down to first joint throughout, just can prevent to open the umbrella when the extension rib from upturning, has solved the problem that the extension rib upturns, and the user has just avoided the action that needs to turn over back to reset manually, and it is more convenient to use, and user's experience is felt better. Therefore, the utility model has the advantages that the lengthened ribs are not easy to be upturned when the umbrella is opened, the use is more convenient, and the experience of the user is better.
