Detailed Description
The invention is further described below by means of specific embodiments.
Referring to fig. 1 to 5, the spring steel sheet type bone fracture umbrella comprises a middle rod 1, an umbrella rib 2, an ejecting mechanism 3 and a knocking mechanism 4.
The utility model provides a spring steel sheet formula broken bone umbrella includes well stick 1, a plurality of rib 2, umbrella face 23, pop-up mechanism 3, beats mechanism 4, and well stick 1 is the main part of this umbrella, is equipped with hollow portion 12 in the well stick 1, and the hollow portion 12 one end of well stick is formed with opening 11, and one end is sealed, and other mechanisms are all located in the hollow portion 12 of well stick, save space, conveniently carry.
Pop-up mechanism 3 is located in hollow portion 12 of well stick 1, including removing seat 31, spring 32, on rib 2 located removal seat 31 through deformation section 21, remove seat 31 bottom and be equipped with second inclined plane 311, spring 32 is located between the bottom surface of removing seat 31 and the hollow portion 12 of well stick, and spring 32 has the spring force that makes removal seat 31 move towards the opening direction, still includes stopper 33, switch 34, stopper 33 can restrict to remove seat 31 and be located the hollow portion 12 bottom of well stick to make spring 32 keep the compression state, switch 34 extends outside well stick 1 and control stopper 33 on-off state, and press the switch makes pop-up mechanism 3 remove limit state, upwards pops out.
The one end of opening 11 is equipped with rapping mechanism 4 in hollow portion 12 of well stick 1, including locating a plurality of rapping pieces 41 of well stick opening 11 department, annular back shaft 42, torsional spring 43, each rapping piece 41 corresponds each rib 2 respectively, each rapping piece 41 is rotatable to be located on annular back shaft 42, rapping piece 41 upper portion is equipped with the cone 411 towards well stick 1 axis direction, rapping piece 41 lower part is equipped with first inclined plane 412, remove seat 31 upper outer edge and form second inclined plane 311, remove seat 31 and when rapping mechanism 4 contact, second inclined plane 311 extrudes each other with first inclined plane 412, make rapping piece 41 rotate, and then drive each cone 411 towards well stick 1 axis direction and rap, because the elasticity of spring 32 is greater than the torsional spring 43 elasticity of rapping mechanism 4 bottom pop-up mechanism 3, make rapping piece 41 can't resume initial position until the umbrella state this moment. When the umbrella ribs 2 extend out of the hollow part 12, the knocking block 41 knocks the deformation section 21 of each umbrella rib 2, the deformation section 21 is changed from a vertical state to a bending state, and the straight section 22 is driven to turn outwards so as to open the umbrella cover. In the opening 11 of well stick 1 was located to annular support shaft 42, annular support shaft 42 passed through fixed block 421 and the hollow portion 12 inner wall fixed connection of well stick 1, rib 2 passes in by annular support shaft 42's annular middle part, torsional spring 43 locates to beat and beats between piece 41 and the annular support shaft 42, and torsional spring 43 has the spring force that makes the conical head 411 of beating piece 41 keep away from well stick 1 axis direction, and initial operating position bounces guarantees not to contact with rib 2 deformation section 21 under the condition of receipts umbrella. The passing path width formed by the tapping mechanism 4 at the opening 11 of the middle rod is smaller than the required passing path width of the movable seat 31, so that the movable seat 31 is limited and clamped by the tapping mechanism 4 at the opening 11, and the movable seat 31 cannot be ejected from the opening 11 of the middle rod.
The spring steel sheet type bone fracture umbrella has the following working principle:
opening the umbrella: in the closed umbrella state, the umbrella ribs 2, the umbrella cover 23 pop-up mechanism 3 and the knocking mechanism 4 are all accommodated in the hollow part 12 of the central rod 1; when the umbrella is opened, the switch 34 is pressed, the position limiter 33 releases the position limitation, the moving seat 31 of the ejecting mechanism 3 drives each umbrella rib 2 to extend out from the opening 11 at one end of the hollow part 12, when the deformation section 21 of each umbrella rib 2 reaches the working range of the knocking block 41 of the knocking mechanism 4 positioned at the opening, the second inclined surface 311 of the ejecting mechanism 3 impacts the first inclined surface 412 of the knocking block 41, because the ejecting force of the ejecting mechanism 3 is larger than the spring force of the torsion spring 32 on the knocking block 41, the knocking block 41 rotates around the annular support shaft 42, so that the knocking block 41 knocks towards the direction of the umbrella rib 2, the conical head 411 of the knocking block 41 is triggered to work, the knocking block 41 knocks the arc-shaped convex surface of the deformation section 21, the arc-shaped support structure of the deformation section 21 is disabled, the deformation section 21 is changed from the vertical state to the bending state, because the width of the passing path formed at the middle rod opening 11 by the knocking mechanism 3 is smaller than the width of the passing path, so that the pop-up mechanism 3 does not continue to pop up and interacts with the rapping block 41, preventing a second rapping of the rapping block 41. Each straight section 22 extending out of the hollow part 12 and connected with the deformation section 21 is turned downwards, so that the umbrella cover 23 connected with each straight section 22 is unfolded, and the umbrella opening action is completed;
the umbrella is folded: in the state of opening the umbrella, the deformation section 21 of the umbrella rib 2 is in the bending state, the straight section 22 of each umbrella rib 2 is manually turned upwards and gathered into a bundle and is pinched to the center of the umbrella rib, so that the deformation section 21 of the umbrella rib 2 can not contact with the knocking block 41 again to generate secondary bending, the umbrella rib 2 gathered into the bundle is pushed towards the inner direction of the hollow part 12 of the middle rod 1, the pushing force is larger than the ejecting force of the ejecting mechanism 3, the ejecting mechanism 3 moves towards the bottom of the hollow part 12, in the moving process, the second inclined surface 311 of the moving seat 31 is separated from the first inclined surface 412 of the knocking block, at the moment, the mutual extrusion force of the first inclined surface 412 and the second inclined surface 311 is lost, the ejecting mechanism 3 is separated from the knocking mechanism 4, the knocking mechanism 4 recovers the initial working position, the knocking block 41 does not extrude the deformation section 21 of the umbrella rib 2 any more, the deformation section 21 is changed into, the umbrella ribs 2 integrated into a bundle are continuously pushed towards the hollow part 12 of the central rod 1 until the umbrella ribs 2 are completely contained in the hollow part 12 of the central rod 1, at the moment, the limiting device 33 continuously plays a role to prevent the ejecting mechanism 3 from ejecting upwards, and the ejecting mechanism is clamped with the inner bottom of the central rod 1 to finish the umbrella-collecting action.
The above description is only an embodiment of the present invention, but the design concept of the present invention is not limited thereto, and any insubstantial modifications made by using the design concept should fall within the scope of infringing the present invention.
