The technical scheme is that an upper disc and a lower disc of a sliding body are integrated, one end of a tension spring is positioned in a radial gap of the lower disc of the sliding body, an iron wire surrounds the radial gap of the lower disc and penetrates through a through hole at the end of the tension spring, so that the tension spring is connected with the lower disc, and the other end of the tension spring is connected to the hinge position of a traction rod and a folding rod. The utility model is labor-saving and material-saving and is convenient to use.

Description

Multi-fold tension spring automatic umbrella

Technical field:

The utility model relates to the technical field of umbrellas, in particular to a multi-fold extension spring type automatic umbrella.

Background technique:

At present, the automatic umbrella used by people is shown in Figure 1, the sliding body 6 connected by the upper plate 61 and the lower plate 62 through the spring 10 is sleeved on the telescopic rod 7, and one end of the steel wire 9 is connected to the draw bar 82 of the skeleton 8. The other end is connected with the annular steel wire in the radial notch of the lower plate 62 of the sliding body 6, and the draw bar 82 and the folding rod 81 are respectively connected on the upper plate 61 of the sliding body 6 and the baffle plate 20, and the baffle plate 20 is fixed. Be connected to telescopic rod 7 tops. To fold the automatic umbrella, first pull down the lower plate 62 connected with the steel wire 9, the steel wire 9 pulls the draw bar 82 to shrink inwardly, and then drives the skeleton 8 to also shrink inwardly, and the draw bar 82 contracted inwardly is opposite to the upper plate 61 A downward pressure is generated to move the upper plate 61 downward and compress the spring 10. When the sliding body 6 is restricted, the automatic umbrella is folded away; when the sliding body 6 is out of the restriction, the compressed spring 10 generates an upward movement. Restoring force pushes the sliding body 6 to move upwards, and then drives the steel wire 9 and the skeleton 8 connected to the sliding body 6 to move upwards together, thereby stretching the automatic umbrella. Because the cross-sectional area of the spring 10 connecting the upper plate 61 and the lower plate 62 is large, its restoring force is also large, and the user needs to spend a lot of effort when putting away the folding umbrella. It is very inconvenient to use when old, young, women and children are used as users. Existing this structure causes the waste of material, and spring 10, steel wire 9 can be replaced by a part fully.

Invention content:

The purpose of the utility model is to provide a multi-fold extension spring type automatic umbrella which saves labor and materials.

The utility model is realized through the following technical scheme: the upper plate and the lower plate of the sliding body are integrated, one end of the extension spring is connected to the lower plate, and the other end is connected to the hinge joint of the traction rod and the folding rod.

The utility model realizes that the two parts of spring and steel wire in the existing automatic umbrella structure are replaced by one extension spring, which saves materials; in addition, the sectional area of the extension spring is much smaller than that of the spring in the existing automatic umbrella. Therefore, the force required for compressing the extension spring is also small, and the umbrella can be retracted easily, thereby achieving the purpose of saving labor.

Description of drawings:

Accompanying drawing 1 is the partial three-dimensional structural diagram of existing automatic umbrella;

Accompanying drawing 2 is the partial three-dimensional structural diagram of the utility model.

See attached drawing 2, the stop plate 1 is fixed on the top of the telescopic rod 2, the sliding body 3 is sleeved on the telescopic rod 2, one end of the folding rod 41 of the skeleton 4 is inserted into the radial gap 11 of the stop disc 1, and the iron wire is wrapped around the stop disc 1 In the radial groove 12 of the frame 4 and through the side wall through hole of this end of the folding rod 41, it is connected to the radial gap 11 of the baffle plate 1. One end of the drawing rod 42 of the skeleton 4 is hinged with the folding rod 41, and the other end Adopt the connection mode of folding rod 41 and retaining plate 1 to be connected in the radial notch of the upper plate 31 of sliding body 3, the upper plate 31 of sliding body 3, the lower plate 32 are one, one end of tension spring 5 is in sliding body 3 In the radial notch of the lower plate 32, the iron wire goes around the radial notch of the lower plate 32 and passes through the through hole at this end of the extension spring 5, so that the extension spring 5 is connected with the lower plate 32, and its other end is connected with the draw bar 42 and the folding bar. 41 hinges.

Detailed ways:

According to the above connection method, the stop plate 1, the telescopic rod 2, the sliding body 3, the skeleton 4, and the tension spring 5 are combined together. When the contracted sliding body 3 is out of the constraint, the tension spring 5 generates a restoring force to drive the sliding body 3 along the telescopic rod. 2 slide upwards, the folding rod 41 of the skeleton 4 is stretched upwards under the action of thrust and drives the traction rod 42 and the extension spring 5 connected together to move upwards, when the sliding body 3 collides with the retaining plate 1, the movement stops and the umbrella is supported Open; Desire to pack up the automatic umbrella, pull down the sliding body 3 firmly, and the extension spring 5 connected thereto produces a downward restoring force to drive the folding rod 41 connected thereto, the drawbar 42 shrinks inwardly, and completes the folding of the umbrella.
