Specific implementation

[0022] In order to make the technical personnel of the prior art better understand the technical scheme of the utility model, the utility model will be introduced further in the following with the attached drawing.

[0023] As Figures 1-6 The utility model embodiment provides a fixed assembly of polygon umbrella rod, including pole body 1, the inner wall of pole body 1 is integrally formed with the reinforcing rib 3 that is centrally symmetric distribution, and one side of pole body 1 is provided with center shaft 4, and one end of center shaft 4 is integrally formed with connecting column 2, and the inside of connecting column 2 is opened with insertion hole 23, and pole body 1 is inserted in the inside of insertion hole 23, and one end of connecting column 2 is provided with installation mouth 6, and the inside of installation mouth 6 is hinged with cam 7, and one side outer wall of cam 7 is integrally formed with force plate 8, and one end of force plate 8 is integrally formed with circular ring 9.

[0024] Specifically, in the embodiment, the rod body 1 is the umbrella rod at the bottom of the fishing umbrella, and the bottom end thereof needs to be fixed to the ground during use. The cross section of the rod body 1 is a regular polygon, and the number of sides can be fourteen, fifteen or sixteen. When the cross section of the rod body 1 is a regular fourteen-sided polygon, the outer wall thereof presents a fourteen-rib structure. When the cross section of the rod body 1 is a regular fifteen-sided polygon, the outer wall thereof presents a fifteen-rib structure. When the cross section of the rod body 1 is a regular sixteen-sided polygon, the outer wall thereof presents a sixteen-rib structure. Specifically, the regular fifteen-sided polygon is preferred, thereby having a better bending resistance. The inner wall of the rod body 1 is integrally formed with the center-symmetrically distributed reinforcing ribs 3. The reinforcing ribs 3 improve the bending resistance and surface deformation resistance of the rod body 1. One side of the rod body 1 is provided with a central shaft 4. One end of the central shaft 4 is integrally formed with a connecting column 2. The connecting column 2 is internally provided with a plug-in hole 23. The plug-in hole 23 is also a regular polygon, and the size thereof matches that of the rod body 1. The rod body 1 is plugged into the plug-in hole 23. One end of the connecting column 2 is provided with a mounting port 6. The mounting port 6 is hingedly provided with a cam 7. When the cam 7 rotates, the edge thereof has a tendency to press the rod body 1. One side of the outer wall of the cam 7 is integrally formed with a force plate 8. The force plate 8 increases the force arm, thereby making the rotation of the cam 7 more convenient. One end of the force plate 8 is integrally formed with a circular ring 9. The circular ring 9 can be inserted into a finger, thereby facilitating the rotation of the force plate 8.

[0025] The fixing assembly of the polygonal umbrella rod provided by the utility model can rotate the force plate 8, fix the rod body 1 plugged into the connecting column 2 by the cam 7, and thus make the fixing of the connecting column 2 and the rod body 1 more convenient, thereby achieving the effect that the fishing umbrella is more convenient to adjust in height.

[0026] In another embodiment of the utility model, the inside of the mounting port 6 is provided with a metal pad 10 between the rod body 1 and the cam 7. The side wall of the rubber layer 11 close to the rod body 1 is fixed to the outer wall of the metal pad 10. The side wall of the rubber layer 11 contacts the side wall of the rod body 1, so that the rod body 1 can be protected when being fixed by pressing. The metal pad 10 and the rubber layer 11 increase the pressing area, so that the rod body 1 is not easy to deform when being pressed.

[0027] In another embodiment of this utility model, a rod sleeve 5 is sleeved on the outside of the central shaft 4, and a movable sleeve 12 sleeved on the outside of the central shaft 4 is inserted into the inside of the rod sleeve 5. The outer wall of the movable sleeve 12 is integrally formed with insert plates 19 distributed in a centrally symmetrical manner. The inner wall of the rod sleeve 5 has insert grooves 18 distributed in a centrally symmetrical manner. The insert plates 19 and the insert grooves 18 are adapted to each other. When the insert plates 19 and the insert grooves 18 are engaged, the rod sleeve 5 and the movable sleeve 12 cannot rotate. One end of the insert plate 19 is provided with a wedge end 20. The wedge end 20 makes it easier for the insert plate 19 and the insert groove 18 to engage. The outer wall of the rod sleeve 5 is fixed with a positioning post 24. When in use, the handle of the umbrella is fixed with the positioning post 24.

[0028] In another embodiment of this utility model, the outer wall of the movable sleeve 12 is integrally formed with a retaining ring 14, and the outer wall of the retaining ring 14 is integrally formed with a baffle 15. The baffle 15 facilitates the movement of the movable sleeve 12. The outer wall of the central shaft 4 is integrally formed with a retaining ring 22, and the rod sleeve 5 is located between the retaining ring 14 and the retaining ring 22. One end of the central shaft 4 is fixed with a baffle plate 13, and the outside of the central shaft 4 is sleeved with a spring 21 located between the baffle plate 13 and the retaining ring 14. The spring 21 can apply elastic force to the movable sleeve 12, so that the insertion plate 19 and the insertion groove 18 maintain the insertion tendency. The interior of the central shaft 4 has a limit groove 16, and the interior of the retaining ring 14 is inserted into the groove. A limiting post 17 is connected, with one end of the limiting post 17 extending into the interior of the limiting groove 16. Using the limiting post 17 and the limiting groove 16, the movable sleeve 12 can only move along the axial direction of the central axis 4. The movable sleeve 12 cannot rotate with the central axis 4. The elastic force of the spring 21 causes the insertion plate 19 to engage with the insertion groove 18 on the inner wall of the rod sleeve 5. When adjusting the rotation of the rod sleeve 5, the movable sleeve 12 can be moved directly until the insertion plate 19 is separated from the insertion groove 18. After adjustment, the insertion plate 19 can automatically engage with the insertion groove 18 through the elastic force of the spring 21. The whole operation is simple, making it more convenient to adjust the angle of the fishing umbrella.

[0029] Working principle: When it is necessary to fix the connecting post 2 to the rod body 1, the force plate 8 rotates the cam 7, causing the cam 7 to press the metal pad 10, thereby fixing the rod body 1 with the rubber layer 11 on one side of the metal pad 10 through friction. When it is necessary to rotate the rod sleeve 5 outside the central shaft 4 by a certain angle, the retaining ring 14 is first pressed against the retaining plate 13, causing the insertion plate 19 to disengage from the insertion groove 18. Then, after rotating the rod sleeve 5, the retaining ring 14 is released, allowing the insertion plate 19 to re-engage with the insertion groove 18 through the elastic force of the spring 21, thereby fixing the rod sleeve 5 to the central shaft 4, making it more convenient to adjust the angle of the fishing umbrella connected to the rod sleeve 5.

[0030] The above has only described certain exemplary embodiments of the present application by way of illustration, and it is needless to say that the described embodiments can be modified in various ways without departing from the spirit and scope of the present application for those skilled in the art. Therefore, the above drawings and descriptions are illustrative in nature, and should not be understood as limiting the scope of protection of the claims of the present application.
