Description

Technical Field

[0001] The utility model belongs to the technical field of Roman umbrellas and relates to a windproof Roman umbrella frame. Background Art

[0002] A Roman umbrella is a commonly used outdoor leisure product. When in use, it needs to be opened by pushing the armrest shell upwards. The upper umbrella disk and the lower umbrella disk are connected by a pull rope. During the opening process, the pull rope is continuously tightened by a hand crank assembly in the hand crank shell. The lower umbrella disk is inserted onto the upper umbrella disk to achieve the axial positioning of the upper umbrella disk and the lower umbrella disk. However, in strong wind weather, circumferential rotation may occur between the insertion rod and the connecting rod, thus affecting the stability of the umbrella surface support.

[0003] The existing one, such as the Chinese patent application [Authorization Publication No.: CN21525013U], discloses a swing angle mechanism for an inclined hanging umbrella, including an umbrella body, a support rod assembly, an umbrella column, a swing angle device, and a lifting handle. The umbrella body is connected to the umbrella column through the support rod assembly. A swing angle device and a lifting handle are provided between the support rod assembly and the umbrella column. The umbrella body consists of an upper umbrella disk, a lower umbrella disk, upper umbrella ribs, and lower umbrella ribs. The upper umbrella ribs are installed on the upper umbrella disk and are used to install and fix external umbrella ribs. One end of the lower umbrella rib is installed on the lower umbrella disk, and the other end is hinged below the middle of the upper umbrella rib. The lower umbrella disk is arranged below the upper umbrella disk and is connected to the upper umbrella disk through a guide rod. The upper umbrella disk is fixedly connected to the upper end of the guide rod, and the lower umbrella disk can slide up and down along the guide rod.

[0004] In the above structure, the lower umbrella disk is connected to the upper umbrella disk through the guide rod on the lower umbrella disk. Since the lower umbrella disk is usually connected to the upper umbrella disk through a pull rope during movement, a longer guide rod is provided on the lower umbrella disk, resulting in more difficult pulling of the lower umbrella disk, thereby increasing the difficulty of opening the umbrella. Moreover, through the setting of the guide rod, the circumferential positioning of the upper umbrella disk and the lower umbrella disk cannot be achieved, resulting in easy circumferential shaking of the upper umbrella disk and the lower umbrella disk when the inclined hanging umbrella encounters strong wind weather, affecting the stability of the inclined hanging umbrella. Summary of the Utility Model

[0005] The purpose of the utility model is to address the above problems existing in the prior art and propose a windproof Roman umbrella frame. The technical problem to be solved by the utility model is: how to solve the problem that the upper umbrella disk and the lower umbrella disk of the existing Roman umbrella frame are prone to circumferential shaking.

[0006] The purpose of the utility model can be achieved by the following technical solutions:

[0007] A windproof Roman umbrella frame, comprising a vertical column, a pull rod connected to the upper end of the vertical column, and an inclined rod slidably connected to the vertical column. The upper end of the inclined rod is connected with an upper umbrella disc, the middle part of the inclined rod is connected with a connecting umbrella rib, the lower end of the connecting umbrella rib is connected with a lower umbrella disc, and the middle part of the inclined rod is hinged to the lower end of the pull rod. It is characterized in that the lower end of the upper umbrella disc is provided with a connecting component, the connecting component includes a connecting sleeve, a chute is arranged on the inner side wall of the connecting sleeve, the upper end of the lower umbrella disc is provided with a plug rod, and an edge is arranged on the outer side wall of the plug rod along the length direction of the plug rod. The plug rod can be inserted into the connecting sleeve, and the edge slides along the chute and fits with the wall of the chute.

[0008] Working principle: By providing a connecting component at the lower end of the upper umbrella disc, the connecting component includes a connecting sleeve, and by providing a plug rod at the upper end of the lower umbrella disc. When opening the umbrella, the lower umbrella disc gradually approaches the upper umbrella disc and inserts the plug rod into the connecting sleeve. At this time, the edge on the plug rod slides along the chute and fits into the chute and fits with the wall of the chute. Through the cooperation of the edge on the plug rod and the chute in the connecting sleeve, the circumferential positioning of the upper umbrella disc and the lower umbrella disc is realized. In strong wind weather, the upper umbrella disc and the lower umbrella disc will not have circumferential shaking, so the windproof performance of the entire umbrella frame is improved. By providing a connecting sleeve and a plug rod, the edge and the chute can cooperate with each other to realize the limit of the upper umbrella disc and the lower umbrella disc. And because the edge is arranged along the length direction of the plug rod, the overall strength of the edge is relatively high. Therefore, when the wind force is large, it can not only play a limiting role, but also enhance the strength of the plug rod, and can further improve the windproof performance of the umbrella frame.

[0009] In the above-mentioned windproof Roman umbrella frame, the connecting component includes a connecting rod fixedly connected to the upper umbrella disc. The lower end of the connecting rod is sleeved with the above-mentioned connecting sleeve, and the connecting rod and the connecting sleeve are connected radially through a fastener.

[0010] The connecting rod of the connecting component is convenient for connecting with the upper umbrella disc, so that only on the basis of the existing upper umbrella disc and connecting rod, adding a connecting sleeve and radially positioning the connecting sleeve on the connecting rod through a fastener can realize the circumferential positioning of the upper umbrella disc and the lower umbrella disc, and at the same time, the improvement of the existing umbrella frame structure is small, so the improvement cost is reduced.

[0011] In the above-mentioned windproof Roman umbrella frame, the plug rod is a polygonal rod, and a plurality of the above-mentioned edges are formed at the corners of the polygonal rod. The inner cavity of the connecting sleeve is a polygonal cavity, and a plurality of the above-mentioned chutes are formed at the corners of the inner cavity of the connecting sleeve. The edges and the chutes are arranged in one-to-one correspondence and slide along the corresponding chutes.

[0012] By setting the insertion rod as a polygonal rod and the inner cavity of the connecting sleeve as a polygonal cavity, the edges at the corners of the polygonal rod can slide along the chutes at the corners of the corresponding inner cavity, making the forces on all parts of the connecting sleeve and the insertion rod uniform, improving the connection stability, and also making the processing of the polygonal rod more convenient.

[0013] Specifically, as an optimization, the insertion rod is a hexagonal rod, and the inner cavity of the connecting sleeve is a hexagonal cavity.

[0014] In the above-mentioned windproof Roman awning frame, the outer side walls of the insertion rods all have a plurality of guiding walls arranged at intervals, the edges are arranged alternately with the guiding walls, and both the guiding walls and the edges are inclined outward from top to bottom.

[0015] The setting of this structure enables the insertion rod to be inserted into the connecting sleeve more smoothly and quickly, and better realizes upward limiting after insertion, further improving the convenience and stability of opening the awning.

[0016] In the above-mentioned windproof Roman awning frame, the upper end of the connecting sleeve has an annular limiting flange, and the upper end of the insertion rod can abut against the limiting flange.

[0017] The setting of the limiting flange can improve the connection stability between the insertion rod and the connecting sleeve, and also improve the strength of the connecting sleeve itself and the connection strength.

[0018] In the above-mentioned windproof Roman awning frame, a connecting hole is formed in the middle of the limiting flange, and the fastener is inserted through the connecting hole and radially presses the limiting flange against the connecting rod.

[0019] By opening the connecting hole at the limiting flange, the strength of the connecting sleeve is the highest at the limiting flange at this time. Therefore, directly connecting through the fastener can improve the connection strength between the connecting sleeve and the connecting rod, and does not affect the limiting of the insertion rod by the connecting sleeve.

[0020] In the above-mentioned windproof Roman awning frame, the lower end of the connecting rod has a conical plug-in head, the lower end of the plug-in head has a circular arc chamfer, a plug-in groove is formed in the middle of the insertion rod, and the lower end of the connecting rod and the plug-in head are embedded in the plug-in groove and the outer side wall of the connecting rod fits with the groove wall of the plug-in groove.

[0021] The setting of this structure enables the connecting rod to be more quickly embedded into the plug-in groove of the insertion rod through the plug-in head, and through the outer side wall of the connecting rod fitting with the groove wall of the plug-in groove and the inner side wall of the connecting sleeve corresponding to the outer side wall of the insertion rod, thereby improving the strength of the connection part. Further, while facilitating the opening of the awning frame, the strength of the awning frame at the connection part is improved.

[0022] Compared with the prior art, the advantages of the windproof Roman umbrella frame of the present invention are as follows: by providing a connecting sleeve and a plugging rod, the upper umbrella disk and the lower umbrella disk can be limited through the mutual cooperation of the edge and the chute. And because the edge is arranged along the length direction of the plugging rod, the overall strength of the edge is relatively high. Therefore, when the wind force is relatively large, it can not only play a role in limiting, but also enhance the strength of the plugging rod, further improving the windproof performance of the umbrella frame.
