Description

Technical Field

[0001] The utility model relates to the technical field of outdoor equipment, in particular to a connecting piece based on a plum blossom tube. Background Art

[0002] The applicant previously disclosed a connector based on a petal tube with publication number CN216812410U, comprising a plug and a socket, wherein the plug comprises a plug petal body corresponding to the inner cavity shape of the petal tube and capable of being inserted from one end of the petal tube, one end of the plug petal body being fixedly connected to a column, and one or more locking posts being fixedly connected near the end of the column, and an angle between the axial direction of the locking post and the radial direction of the petal closest thereto is 40°-60°; the socket comprises a socket petal body corresponding to the inner cavity shape of the petal tube and capable of being inserted from one end of the petal tube, a middle hole slightly larger than the column and a petal hole similar in shape to and slightly smaller than one or more of the petals are provided axially along the socket petal body, the middle hole being connected to the petal hole and suitable for accommodating the passage of the column and the locking post, and a locking hole is provided on the socket petal body, corresponding to the radial direction of the petal hole, and within the range of the angle turned clockwise and / or counterclockwise. Although this connector can be easily disassembled and assembled, it is not allowed in certain application scenarios due to the certain fitting gap between the plug and socket and the petal tube. For example, the petal tube is used as the handle of a large parasol. In order to facilitate miniaturization, the handle is composed of two sections of petal tube connected by this connector. Since there is a certain fitting gap between the plug and socket and the petal tube, the handle of the parasol will shake, affecting safety in use. Utility Model Content

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0022] like Figure 1 As shown, a large outdoor parasol, the umbrella handle is formed by connecting a first section of plum blossom tube 100 located at the top and a second section of plum blossom tube 200 located at the bottom through a connecting piece. Figure 2-6 As shown, it includes a first connector 1 and a second connector 2, the first connector 1 includes a first plug-in portion 11 corresponding to the inner contour shape of the first section of the plum blossom tube 100 and having an interference fit with the first section of the plum blossom tube 100, a first connecting plate 12 having the same outer contour shape as the first section of the plum blossom tube 100 and fixedly connected to the first plug-in portion 11, the left half of the end surface of the first connecting plate 12 extends to the opposite side of the first plug-in portion 11 to form a first docking portion 13, and a first through hole 14 is provided on the side of the first docking portion 13; the second connector 2 includes a second plug-in portion 21 corresponding to the inner contour shape of the second section of the plum blossom tube 200 and having an interference fit with the second section of the plum blossom tube 200, and a first connecting plate 12 having the same outer contour shape as the first section of the plum blossom tube 100 and fixedly connected to the first plug-in portion 11, the left half of the end surface of the first connecting plate 12 extends to the opposite side of the first plug-in portion 11 to form a first docking portion 13, and a first through hole 14 is provided on the side surface of the first docking portion 13; A second connecting plate 22 having the same outer contour shape as the plum blossom tube 200 and fixedly connected to the second plug-in portion 21, the right half of the end face of the second connecting plate 22 extends to the opposite side of the second plug-in portion 21 to form a second docking portion 23, and a second through hole 24 is provided on the side face of the second docking portion 23 at a position corresponding to the first through hole 14; the second docking portion 23 is equal in height to the first docking portion 13, and after the second docking portion 23 and the first docking portion 13 are abutted, the overall outer contour shape is the same as the outer contour shape of the first section of the plum blossom tube 100 or the second section of the plum blossom tube 200; the screw rod 3 passes through the second through hole 24 and the first through hole 14 and is screwed with a nut to fix the first connector 1 and the second connector 2 into one.

[0023] Since the second docking portion 23 is equal to the height of the first docking portion 13, after the second docking portion 23 and the first docking portion 13 are abutted, the free end of the first docking portion 13 abuts against the left half of the end face of the second connecting plate 22, and the free end of the second docking portion 23 abuts against the right half of the end face of the first connecting plate 12, and the second docking portion 23 abuts against the side face of the first docking portion 13. In this way, after the screw 3 and the nut fix the first connecting body 1 and the second connecting body 2 into one, the first connecting body 1 and the second connecting body 2 have no space for movement in the axial and radial directions, so they are very stable and will not shake. At the same time, after the second docking portion 23 and the first docking portion 13 are abutted, the overall outer shape is the same as the outer shape of the first section of the plum blossom tube 100 or the second section of the plum blossom tube 200, and will not affect the movement of the outer sliding seat of the umbrella handle when the parasol is opened and closed.

[0024] In another preferred embodiment, a groove 15 is provided on the side of the first docking portion 13, and a convex rib 25 is provided on the side of the second docking portion 23 accordingly, and the convex rib 25 and the groove 15 are clearance-fitted or transition-fitted; the height of the convex rib 25 is less than or equal to the depth of the groove 15. In this way, the cooperation between the convex rib 25 and the groove 15 can further enhance the stability of the connection between the first connector 1 and the second connector 2.

[0025] In another preferred embodiment, the outer end of the first through hole 14 is provided with a hexagonal countersunk hole 16 suitable for inserting a hexagonal nut, and the outer end of the second through hole 24 is provided with a circular countersunk hole 26 suitable for sinking the hexagonal nail head of the screw rod 3. In this way, the hexagonal nail head and the nut of the screw rod 3 will not be exposed, and will not affect the movement of the outer sliding seat of the umbrella handle when the parasol is opened and closed. At the same time, after the hexagonal nut is inserted into the hexagonal countersunk hole 16, there is no need to fix the nut during the process of screwing in or out.

[0026] The utility model can be summarized in other specific forms that do not violate the spirit or main features of the utility model. Therefore, no matter from which point of view, the above embodiments of the utility model can only be regarded as an explanation of the utility model and cannot limit the utility model. The claims indicate the scope of the utility model, while the above description does not indicate the scope of the utility model. Therefore, any changes within the meaning and scope equivalent to the claims of the utility model should be considered to be included in the scope of the claims of the utility model.
