Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of umbrellas, in particular to a pivot pin structure in which umbrella ribs are pressed into pivot connection. Background Art
[0002] An umbrella generally consists of an umbrella surface, a middle rod as the main support, a number of main ribs for supporting the umbrella surface, supporting ribs for opening the umbrella surface, and an umbrella head at the end of the middle rod. The main ribs and the supporting ribs are generally connected using a tubular pin. After the pin is inserted into the pivot holes provided on the main ribs and the supporting ribs, the four-petal iron sheet at the end of the pin is bent so that the pin is limited in the pivot hole. Although this method has a simple structure, the installation process is more troublesome and it is not easy to disassemble. Therefore, a new type of axis pin structure is needed to solve this problem. Utility Model Content
[0003] Other features and advantages of the utility model will be described in the following description, and partly become apparent from the description, or understood by implementing the utility model. The purpose and other advantages of the utility model can be realized and obtained through the structures specifically pointed out in the description and other drawings of the description.
[0004] The utility model aims to overcome the above-mentioned drawbacks and provide a pivot pin structure for pivoting an umbrella rib.
[0005] To achieve the above-mentioned purpose, the technical solution of the utility model is: a pivot pin structure in which an umbrella rib is pressed and pivoted, comprising a main umbrella rib and a supporting umbrella rib, wherein the main umbrella rib and the supporting umbrella rib are both provided with a pivot hole, wherein a pivot pin is penetrated through the pivot hole, wherein the main umbrella rib and the supporting umbrella rib are rotatably connected via the pivot pin, wherein the pivot pin comprises a contact portion as a rotation axis, wherein one end of the contact portion is provided with a limiting portion for limiting the pivot pin from being separated from the pivot hole, wherein the limiting portion abuts against the supporting umbrella rib or the main umbrella rib, wherein the other end of the contact portion is provided with a clamping portion for keeping the pivot pin in the pivot hole, wherein the contact portion is provided with an elastic portion which enables the contact portion to deform itself and enables the clamping portion to pass through the pivot hole.
[0006] By adopting the above technical solution and utilizing the elastic part on the pivot nail, one end of the pivot nail with the clamping part can pass through the pivot holes on the main rib and the supporting rib in sequence through deformation, and be clamped on the other side of the main rib or the supporting rib, while the end with the limiting part also abuts against one side of the main rib or the supporting rib as the pivot nail is inserted into the pivot hole. The contact part can be kept in the pivot hole through the limiting part and the clamping part, thereby realizing the rotational connection relationship between the main rib and the supporting rib. Compared with the traditional limiting method by inserting the end of the bent pin after insertion, this method can realize the connection between the main rib and the supporting rib by directly pressing in, so that the assembly between the main rib and the supporting rib is more convenient.
[0007] Preferably, the contact part is cylindrical and hollow inside. The utility model enables the main umbrella rib and the secondary umbrella rib to rotate smoothly directly by using the cylindrical contact part. At the same time, the hollow structure can provide conditions for the deformation of the elastic part.
[0008] Preferably, the elastic part is located at one end where the contact part is connected to the clamping part. An activity groove is formed on the elastic part, and the elastic part forms two activity feet through the activity groove. The utility model enables the two activity feet at the end of the contact part to deform inwards by using the activity groove, so that when passing through the pivot hole, the size of the elastic part can be smaller than the diameter of the pivot hole in this way, and thus it can pass through the pivot hole smoothly.
[0009] Preferably, the clamping part is two hooks, and the two hooks are respectively fixedly connected to the ends of the two activity feet. The utility model realizes the clamping of the pivot top end with the main umbrella rib or the secondary umbrella rib by using the hooks. The hooks are convex block structures protruding from the cylindrical surface of the contact part.
[0010] Preferably, the cross-section of the hook is triangular, the upper end of the hook is a plane, and the lower end of the hook is an inclined surface. By using the inclined surface at the lower end of the hook, the utility model enables the pivot pin to bend the two activity feet inwards under the guidance of the inclined surface of the hook during the process of inserting into the pivot hole, so that the pivot pin can pass through the pivot hole. After passing through the pivot hole, the two activity feet will return to their original state, driving the planes on the two hooks to abut against the main umbrella rib or the secondary umbrella rib, so that the pivot pin cannot escape from the pivot hole.
[0011] Preferably, the limiting part is a round plate, and the round plate is fixedly connected to the contact part, and the diameter of the round plate is larger than that of the contact part. By using the round plate with a diameter larger than that of the contact part, the utility model enables the edge of the round plate to exceed the edge of the contact part after the round plate is fixed on the contact part. Thus, when the contact part passes through the pivot hole, it can abut against the main umbrella rib or the secondary umbrella rib, so that the contact part cannot directly pass through the pivot hole, realizing the limit.
[0012] Preferably, a dome structure is arranged on the round plate. The elastic force generated by the deformation of the dome structure in the utility model can enable the hooks at the lower end to closely adhere to the surface of the main umbrella rib or the secondary umbrella rib, thereby preventing the pivot pin from loosening.
[0013] Preferably, the main umbrella rib comprises a plurality of sub-ribs, and each of the sub-ribs is rotatably connected to each other by a pivot pin. The utility model enables the pivot pin to be also applied to the connection between the sub-ribs in a folding umbrella in this way.
[0014] Preferably, several of the sub-bones are mutually driven through linkage bones, and both ends of the linkage bones are rotationally connected to the sub-bones through pivot pins. The pivot pins of the present invention can also be used for the connection between the linkage bones and the umbrella bones in a folding umbrella.
[0015] In summary, the beneficial effects of the present invention are as follows:
[0016] 1. By utilizing the elastic part on the pivot pin, the end of the pivot pin with the clamping part can sequentially pass through the pivot holes on the main umbrella bone and the support umbrella bone by deforming, and be clamped on the other side of the main umbrella bone or the support umbrella bone, while the end with the limiting part also abuts against one side of the main umbrella bone or the support umbrella bone as the pivot pin is inserted into the pivot hole. Through the limitation of the clamping part and the limiting part, the contact part can be kept within the pivot hole. In this way, the assembly of the main umbrella bone and the support umbrella bone is more convenient.
[0017] 2. By utilizing the movable groove, the two movable feet at the end of the contact part can deform inwards, so that when passing through the pivot hole, their size can be made smaller than the diameter of the pivot hole in this way, and thus they can smoothly pass through the pivot hole.
[0018] It should be understood that the above general description and the following detailed description are only exemplary and explanatory, and cannot limit the present disclosure.

In this specification, the schematic expressions of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described can be combined in a suitable manner in any one or more embodiments or examples.
[0031] As Figure 1-2 shown, a pivot shaft nail structure for press-fitting and pivotally connecting umbrella ribs includes a main umbrella rib 1 and a secondary umbrella rib 2. Both the main umbrella rib 1 and the secondary umbrella rib 2 are provided with pivot holes. A pivot nail 3 is penetrated through the pivot holes. The main umbrella rib 1 and the secondary umbrella rib 2 are rotationally connected through the pivot nail 3. The pivot nail 3 includes a contact portion 4 serving as the rotation axis. One end of the contact portion 4 is provided with a limiting portion 5 for restricting the pivot nail 3 from disengaging from the pivot hole. The limiting portion 5 abuts against the secondary umbrella rib 2 or the main umbrella rib 1. The other end of the contact portion 4 is provided with a clamping portion 6 for keeping the pivot nail 3 in the pivot hole. The contact portion 4 is provided with an elastic portion 7 enabling itself to deform and allowing the clamping portion 6 to pass through the pivot hole.
[0032] By adopting the above technical solution, by using the elastic portion 7 on the pivot nail 3, the end of the pivot nail 3 with the clamping portion 6 can pass through the pivot holes on the main umbrella rib 1 and the secondary umbrella rib 2 in sequence through deformation, and be clamped on the other side of the main umbrella rib 1 or the secondary umbrella rib 2. The end with the limiting portion 5 also abuts against one side of the main umbrella rib 1 or the secondary umbrella rib 2 as the pivot nail 3 is inserted into the pivot hole. Through the limitation of the clamping portion 6 and the limiting portion 5, the contact portion 4 can be kept in the pivot hole, realizing the rotational connection relationship between the main umbrella rib 1 and the secondary umbrella rib 2. In this way, compared with the traditional method of limiting by bending the end of the inserted pin, the pivot nail 3 can realize the connection between the main umbrella rib 1 and the secondary umbrella rib 2 by directly pressing in, making the assembly between the main umbrella rib 1 and the secondary umbrella rib 2 more convenient.
[0033] The contact portion 4 is cylindrical and hollow inside. The cylindrical contact portion 4 enables the main umbrella rib 1 and the secondary umbrella rib 2 to rotate smoothly directly, and at the same time, the hollow structure can provide conditions for the deformation of the elastic portion 7.
[0034] The elastic part 7 is located at one end where the contact part 4 is connected to the clamping part 6. An activity groove 8 is formed on the elastic part 7, and the elastic part 7 forms two activity feet 9 through the activity groove 8. By means of the activity groove 8, the two activity feet 9 at the end of the contact part 4 can be deformed inwards, so that when passing through the pivot hole, their size can be made smaller than the diameter of the pivot hole in this way, and thus they can smoothly pass through the pivot hole.
[0035] The clamping part 6 is two hooks, and the two hooks are respectively fixedly connected to the ends of the two activity feet 9. The clamping of the pivot top end with the main umbrella rib 1 or the branch umbrella rib 2 is realized by means of the hooks, and the hooks are convex block structures protruding from the cylindrical surface of the contact part 4.
[0036] The cross-section of the hook is triangular, the upper end of the hook is a plane, and the lower end of the hook is an inclined surface. By means of the inclined surface at the lower end of the hook, when the pivot pin 3 is inserted into the pivot hole, the two activity feet 9 can be bent and deformed inwards under the guidance of the inclined surface of the hook, so that the pivot pin 3 can pass through the pivot hole. After passing through the pivot hole, the two activity feet 9 will recover, driving the planes on the two hooks to abut against the main umbrella rib 1 or the branch umbrella rib 2, so that the pivot pin 3 cannot escape from the pivot hole.
[0037] The limiting part 5 is a disc, the disc is fixedly connected to the contact part 4, and the diameter of the disc is larger than the diameter of the contact part 4. By means of the disc with a diameter larger than that of the contact part 4, after the disc is fixed on the contact part 4, the edge of the disc can extend beyond the edge of the contact part 4. Thus, when the contact part 4 passes through the pivot hole, it can abut against the main umbrella rib 1 or the branch umbrella rib 2, so that the contact part 4 will not directly pass through the pivot hole, realizing the limit.
[0038] A dome structure is arranged on the disc. The elastic force generated by the deformation of the dome structure can make the hook located at the lower end closely adhere to the surface of the main umbrella rib 1 or the branch umbrella rib 2, thereby preventing the pivot pin 3 from loosening.
[0039] The main umbrella rib 1 includes several sub-ribs 10, and each sub-rib 10 is rotatably connected to each other through a pivot pin 3. Each sub-rib 10 is rotatably connected to each other through a pivot pin 3. In this way, the pivot pin 3 can also be applied to the connection between the sub-ribs 10 in a folding umbrella.
[0040] Several sub-ribs 10 are driven by a linkage rib 11, and both ends of the linkage rib 11 are rotatably connected to the sub-ribs 10 through a pivot pin 3. The pivot pin 3 can also be used for the connection between the linkage rib 11 and the umbrella rib in a folding umbrella.
[0041] It should be noted that many specific details are described above for a full understanding of the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Therefore, the protection scope of the present utility model is not limited by the specific embodiments disclosed below.
