Description

Technical Field

[0001] The invention relates to the technical field of umbrella structures, in particular to a wind and rainproof umbrella frame. Background Art

[0002] The design and development of windproof and rainproof umbrella frames is an important research direction in the field of umbrella manufacturing. As people's requirements for the windproof and wind-resistant performance of umbrellas continue to increase, the traditional umbrella frame structure can no longer meet market demand.

[0003] Since the main frame is distributed in a circular shape with equal distances, the outer end of the main frame has a smaller density and is farthest from the supporting point, so it is most likely to bend. When the wind is strong enough, the main frame will break, resulting in poor wind resistance of the umbrella.

[0004] For example, Chinese patent CN2020224772226 proposes a sturdy umbrella rib, which enhances the structural strength of the umbrella rib by adding an elastic telescopic rod to the frame. In terms of structure alone, it can effectively increase the strength of the umbrella rib to increase wind resistance, but it requires adding springs to each frame, and the springs need to have a sufficiently long stroke. Otherwise, either when the umbrella rib is opened, the telescopic rod will no longer be elastic after extending to a certain length and will not be able to support the umbrella rib against wind, or the umbrella rib cannot be completely retracted and closed. The stroke requirement of the spring brings about the length requirement of the spring, resulting in the spring mass being unable to be lightweight, which will cause the problem of being too heavy and laborious to use. Therefore, it is necessary to propose a windproof umbrella frame that can extend the service life of the spring. Summary of the invention

[0005] In order to solve the above technical problems, the present invention provides a wind and rainproof umbrella frame.

[0006] The present invention is implemented by the following technical scheme: it comprises an umbrella handle, the umbrella handle is slidably connected with an outer sliding sleeve, a plurality of main ribs are rotatably connected with the top of the umbrella handle and are distributed at equal distances around the circumference of the umbrella handle, one end of a plurality of supporting ribs is rotatably connected with a plurality of main ribs in a one-to-one correspondence, the other end of the supporting ribs is rotatably connected with the outer sliding sleeve, the non-end point of the supporting ribs is rotatably connected with one end of the supporting ribs, a sliding groove is provided on one side of the main ribs away from the supporting ribs and the umbrella handle, and the other end of the supporting ribs is rotatably connected with a connecting rod One side of the connecting rod is located in the sliding groove and is slidably connected to the main umbrella rib, and a clamp is fixedly installed on the inner wall of the sliding groove on one side close to the first supporting umbrella rib; in this way, when the outer sliding sleeve is pushed upward to open the umbrella ribs, the first supporting umbrella rib opens the main umbrella rib to achieve the first support, and the second supporting umbrella rib drives the connecting rod to move to contact with the clamp and compress the clamp to move to the other side thereof, so that the clamp clamps the connecting rod to fix the second supporting umbrella rib, so that the second supporting umbrella rib supports the outer side of the main umbrella rib, thereby achieving the second support to enhance wind resistance.

[0007] As a further improvement of the above scheme, a clamping groove adapted to the connecting rod is opened on the inner bottom wall of the sliding groove on the side close to the umbrella supporting rib, and the clamping piece matches the clamping groove, so that when the connecting rod is in the clamping groove, the clamping piece contacts the connecting rod and clamps the connecting rod.

[0008] As a further improvement of the above solution, the slot is arc-shaped and matches the connecting rod, so that the second umbrella rib will not shake when the connecting rod is located in the slot.

[0009] As a further improvement of the above solution, the clamping piece is rubber and is hemispherical, so that the connecting rod can pass under the clamping piece.

[0010] As a further improvement of the above solution, there are multiple clamps and they are equidistantly distributed on the inner top wall of the slide slot to prevent the second umbrella rib from losing its supporting effect.

[0011] As a further improvement of the above scheme, the umbrella handle is slidably connected with an inner sliding sleeve located above the outer sliding sleeve, a spring 2 is fixedly installed between the inner sliding sleeve and the outer sliding sleeve, and one end of a plurality of umbrella ribs 1 close to the outer sliding sleeve is rotatably connected to the inner sliding sleeve, so that the umbrella ribs 1 have a certain buffer stroke.

[0012] As a further improvement of the above scheme, the outer sliding sleeve is rotatably connected to one end of a plurality of support rods, and the other ends of the plurality of support rods are rotatably connected to a plurality of umbrella ribs one by one, so that the support rods support the umbrella ribs one to increase the strength of the skeleton.

[0013] As a further improvement of the above scheme, a strip hole parallel to the length direction of the umbrella handle is opened on the outer side wall of the umbrella handle, and a slider is slidably connected in the strip hole, and the slider is rotatably connected to one end of the supporting rib three, and the other ends of several of the supporting ribs three are rotatably connected to the main umbrella ribs one by one, and one ends of several of the sliders are fixedly connected to the connecting plate located inside the umbrella handle, and a spring three is fixedly installed between the top of the connecting plate and the inner top wall of the umbrella handle, and the spring three is in a stretched state, so that the supporting rib three supports the main umbrella rib, thereby realizing the third support to increase the strength of the skeleton.

[0014] Compared with the prior art, the present invention has the following beneficial effects: The present invention designs the first support, the second support and the third support to provide multiple auxiliary supports for the original umbrella ribs, thereby increasing the strength of multiple positions of the frame.

[0015] The force of manually moving the outer sliding sleeve is transmitted through the first supporting umbrella rib to pull the second supporting umbrella rib, so that the connecting rod passes through the clamping piece and is clamped into the clamping groove to fix the second supporting umbrella rib. When there is wind, the second supporting umbrella rib supports the side of the main umbrella rib away from the umbrella handle to prevent the main umbrella rib from breaking. In addition, since the main umbrella rib has a certain toughness, when it is windy, the side of the main umbrella rib away from the umbrella handle is bent and drives the clamping piece to move toward the bottom wall of the sliding groove, which will reduce the distance between the clamping piece and the bottom wall of the sliding groove, so that the connecting rod cannot pass under the clamping piece or needs a greater external force to pass. Therefore, when the wind force is greater, the bending deformation of the main umbrella rib is greater, the resistance of the connecting rod is greater, the supporting force of the second supporting umbrella rib is greater, and the windproof performance of the skeleton is better. Only two supporting ribs, a connecting rod and a clamp are added, and less structure is added to the original frame. While increasing the strength, the overall weight is greatly reduced compared to the weight of a solid rib proposed in Chinese patent CN2020224772226, which is more labor-saving when used; When the wind force is too strong and the first supporting rib is insufficient to support the main rib and the second supporting rib, the support rod can further increase the support force of the first supporting rib to resist a stronger wind force, and by providing the second spring, a part of the force can be released by compressing the second spring before the wind force exceeds the supporting strength of the frame, so as to reduce the strength burden of the frame and enable the frame to resist a higher wind force; Through the above technical solution, when the umbrella is opened, the spring three can automatically unfold the main ribs by pulling the connecting plate and the supporting ribs three. After the umbrella is opened, the slider contacts the inner top wall of the strip hole, and the spring three still maintains a certain pulling force, so that the bottom fulcrum of the supporting rib three is fixed to support the main ribs and increase the skeleton strength.

[0018] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods.

[0019] Please combine Figures 1 to 7 The wind and rainproof umbrella frame comprises an umbrella handle 101, an outer sliding sleeve 103 is slidably connected to the umbrella handle 101, a plurality of main umbrella ribs 116 are rotatably connected to the top of the umbrella handle 101 and are equidistantly distributed around the circumference of the umbrella handle 101, one end of a plurality of umbrella ribs 113 are rotatably connected to the plurality of main umbrella ribs 116 in a one-to-one correspondence, the other end of the umbrella rib 1 113 is rotatably connected to the outer sliding sleeve 103, the non-end point of the umbrella rib 1 113 is rotatably connected to one end of the umbrella rib 2 117, a sliding groove 118 is provided on one side of the main umbrella rib 116 away from the umbrella rib 1 113 and the umbrella handle 101, the other end of the umbrella rib 2 117 is rotatably connected to the connecting rod 104, the One side of the connecting rod 104 is located in the sliding groove 118 and is slidably connected to the main rib 116. A clamp 105 is fixedly installed on the inner wall of the sliding groove 118 near the supporting rib 113, so that when the outer sliding sleeve 103 is pushed upward to open the umbrella ribs, the supporting rib 113 opens the main rib 116 to achieve the first support, and the supporting rib 117 drives the connecting rod 104 to move to contact the clamp 105 and compresses the clamp 105 to move to the other side, so that the clamp 105 clamps the connecting rod 104 and fixes the supporting rib 117, so that the supporting rib 117 supports the outer side of the main rib 116, thereby achieving the second support to enhance wind resistance.

[0020] A hinge seat 115 is fixedly installed on the top of the umbrella handle 101, and a plurality of main ribs 116 are rotatably connected to the hinge seat 115. A grip 102 is wrapped around the outer side of the bottom of the umbrella handle 101 to make it more comfortable to hold. The main ribs 116 have a certain toughness.

[0021] Please combine Figure 3 Figure 4 Figure 7A slot 106 adapted to the connecting rod 104 is provided on the inner bottom wall of the slide groove 118 near the supporting rib 113, and the clamping member 105 matches the slot 106, so that when the connecting rod 104 is located in the slot 106, the clamping member 105 contacts the connecting rod 104 and clamps the connecting rod 104.

[0022] The cross section of the slide groove 118 is in a "T" shape, and the connecting rod 104 is adapted to the slide groove 118, so that the connecting rod 104 will not slide out of the slide groove 118. The middle part of the connecting rod 104 is cylindrical, and the slot 106 is arc-shaped and matches the connecting rod 104, so that when the connecting rod 104 is located in the slot 106, the second umbrella supporting rib 117 will not shake, so that the supporting effect of the second umbrella supporting rib 117 is better.

[0023] The clamp 105 is made of rubber and is hemispherical, so that the clamp 105 has a certain elasticity. After the clamp 105 is compressed, the distance between the clamp 105 and the inner bottom wall of the slide groove 118 is greater than the height of the connecting rod 104, so that the connecting rod 104 can pass under the clamp 105.

[0024] There are multiple clamps 105 equidistantly distributed on the inner top wall of the slide slot 118 , so that the connecting rod 104 will be caught by another clamp 105 after passing through one clamp 105 , preventing the second umbrella rib 117 from losing its supporting effect.

[0025] Through the above technical solution, the force of manually moving the outer sliding sleeve 103 is transmitted through the supporting rib 113 to pull the supporting rib 117, so that the connecting rod 104 passes through the clamping piece 105 and is clamped into the clamping groove 106 to fix the supporting rib 117. When there is wind, the supporting rib 117 supports the side of the main rib 116 away from the umbrella handle 101 to prevent the main rib 116 from breaking. In addition, since the main rib 116 has a certain toughness, when it is windy, the main rib 116 is away from the umbrella handle. When one side of 101 is bent, it drives the clamping member 105 to move toward the bottom wall of the slide groove 118, which reduces the distance between the clamping member 105 and the inner bottom wall of the slide groove 118, so that the connecting rod 104 cannot pass under the clamping member 105 or requires a greater external force to pass through. Therefore, when the wind force is greater, the bending deformation of the main rib 116 is greater, the resistance of the connecting rod 104 is greater, the supporting force of the second supporting rib 117 is greater, and the windproof performance of the skeleton is better.

[0026] The windproof umbrella frame provided by the present invention only adds two supporting ribs 117, a connecting rod 104 and a clamp 105, with little structure added to the original frame. The overall weight is greatly reduced compared to the weight of a sturdy rib proposed in Chinese patent CN2020224772226, and it is more labor-saving when used.

[0027] Please combine Figure 2 Figure 5 Figure 6 The umbrella handle 101 is slidably sleeved with an inner sleeve 111 located above the outer sleeve 103, and a spring 2 112 is fixedly installed between the inner sleeve 111 and the outer sleeve 103. One end of a plurality of ribs 113 close to the outer sleeve 103 is rotatably connected to the inner sleeve 111, so that when the external force is too large and about to exceed the strength of the skeleton structure, the ribs 113 have a certain buffer stroke through the spring 2 112, and can release part of the external force to the spring 2 112.

[0028] The outer sliding sleeve 103 is rotatably connected to one end of a plurality of support rods 114, and the other ends of the plurality of support rods 114 are rotatably connected to a plurality of umbrella ribs 113 one by one, so that the support rods 114 support the umbrella ribs 113 to increase the strength of the frame.

[0029] In the prior art, when the frame is closed, the lower lock buckle of the umbrella buckles the outer sliding sleeve 103 to fix the closed state, and when the frame is pushed to be fully unfolded, the upper lock buckle of the umbrella buckles the outer sliding sleeve 103 to fix the open state. It will not be repeated here. A limit block located above the inner sliding sleeve 111 is fixedly installed on the umbrella handle 101. By setting a second spring 112, when the outer sliding sleeve 103 is buckled by the upper lock buckle, the inner sliding sleeve 111 resists the limit block, and the second spring 112 is in a semi-compressed state, so that when the upper lock buckle is pressed to close the umbrella, the elastic force of the second spring 112 to restore the deformation can make the outer sliding sleeve 103 move downward after being pressed into place, which is convenient for operation and prevents the upper lock buckle from locking the outer sliding sleeve 103 again after the pressing finger is released.

[0030] Through the above technical solution, when the wind force is too strong and the supporting rib 113 is insufficient to support the main rib 116 and the supporting rib 117, the supporting force of the supporting rib 113 can be further increased by the support rod 114 to resist greater wind force, and by providing the spring 2 112, a part of the force can be released by compressing the spring 2 112 before the wind force exceeds the supporting strength of the frame to reduce the strength burden of the frame, so that higher wind force can be resisted.

[0031] Please combine Figure 2 Figure 5 Figure 6A plurality of strip frames 120 are embedded in the outer wall of the umbrella handle 101. The plurality of strip frames 120 are equidistantly distributed around the circumferential direction of the umbrella handle 101 and are equal in number to the main ribs 116. The strip frames 120 are provided with strip holes 110 parallel to the length direction of the umbrella handle 101. A slider 109 is slidably connected in the strip holes 110. The slider 109 is rotatably connected to one end of the supporting rib three 119. The other ends of the supporting ribs three 119 are rotatably connected to the main ribs 116 in a one-to-one correspondence. One ends of the plurality of sliders 109 are fixedly connected to the connecting plate 108 located inside the umbrella handle 101. A spring three 107 is fixedly installed between the top of the connecting plate 108 and the inner top wall of the umbrella handle 101. The spring three 107 is in a stretched state, so that the supporting rib three 119 supports the main rib 116, thereby realizing the third support to increase the strength of the skeleton. In other embodiments, the strip-shaped hole 110 may also be realized by directly opening it on the umbrella handle 101 .

[0032] Through the above technical solution, when the umbrella is opened, the spring three 107 can automatically unfold the main rib 116 by pulling the connecting plate 108 and the supporting rib three 119. After the umbrella is opened, the slider 109 contacts the inner top wall of the strip hole 110, and the spring three 107 still maintains a certain pulling force, so that the bottom fulcrum of the supporting rib three 119 is fixed to support the main rib 116 and increase the skeleton strength.

[0033] The implementation principle of a wind and rainproof umbrella frame in the embodiment of the present application is: By pressing the lower lock buckle, the spring three 107 restores the deformation of the tension to pull the connecting plate 108 upward, driving the supporting rib three 119 to open the main rib 116 to open the frame, and the upper lock buckle clamps the outer sliding sleeve 103 to fix it. By arranging the spring two 112, the support rod 114, the supporting rib two 117 and the supporting rib three 119, the overall strength of the frame is increased to resist wind, and the increased weight is reduced as much as possible for easy use. When it needs to be folded, the upper lock buckle is pressed and the outer sliding sleeve 103 is pulled to be buckled through the lower lock buckle to complete the storage.

[0034] The above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
