Abstract

Disclosed is a folding support used on a backpack sunshade apparatus, the folding support comprising a rotating mechanism (1), and a support (2) connected on the rotating mechanism (1), wherein the support (2) comprises a first support rod (21) and a second support rod (22), one end of the first support rod (21) is fixedly connected on the rotating mechanism (1) and the other end is hinged to one end of the second support rod (22), the other end of the second support rod (22) is connected to an external flexible shade (3), a pull cord (4) is connected on the second support rod (22), and the pull cord (4) passes through the first support rod (21) to connect to a winch (5) located on the rotating mechanism (1).Since the entire opening and folding mechanism is driven by the pull cord (4), and the winch (5) is mounted in the rotating mechanism, the structure is simple, compact and involves few components, such that not only are production costs low, but the action is also smooth and the chance of faults is low.

Description

Folding bracket applied to backpack umbrella sunshade device

Technical field

The invention relates to a backpack umbrella structure, in particular to a folding bracket applied to a backpack umbrella sunshade device.

Background technique

In order to meet the needs of the market, the inventor invented a backpack folding umbrella in 2013. The specific structure can refer to the Chinese invention patents such as 201320199340.2, 201320199373.7, 201320615574.0, 201320615206.6, 201420404419.9. The backpack folding umbrella includes a main body that can be used on the back of the person or put into the backpack together with the backpack. The main body includes a rotating device and a rotating expansion mechanism, and a bracket connected to the rotating device and a flexible mask disposed on the bracket, by rotating The driving action of the device and the rotating expansion mechanism, after the bracket is opened, the flexible mask covers the user's head, and functions as a sunshade and rain. The bracket comprises an outer bracket, a middle bracket and an inner bracket, wherein the outer bracket rotates from the main body of the back to the front of the user, and the length is longer than that of the middle bracket and the inner bracket, so that it is not convenient to be stored after being collected.

Summary of the invention

The invention provides a folding bracket which is simple in structure, convenient in use, low in failure rate and applied to a backpack umbrella sunshade device.

The technical solution adopted by the present invention to solve the technical problem thereof is:

A folding bracket applied to a backpack umbrella sunshade device includes a rotating mechanism and a bracket connected to the rotating mechanism, the bracket includes a first pole and a second pole, and one end of the first pole is fixedly connected On the rotating mechanism, the other end is hinged to one end of the second strut, the other end of the second strut is connected with an external flexible mask, and the second strut is connected with a drawstring, and the drawstring passes through The first rod is connected to a reel located on the rotating mechanism.

In the present invention, the hinge of the first strut and the second strut is provided with a return coil spring.

In the present invention, the drawstring is a wire rope.

In the present invention, the end of the second strut is provided with a convex connecting block that is connected to the drawstring.

In the present invention, the first strut is tubular, and the drawstring runs through the first strut front and rear.

The invention has the beneficial effects that the invention divides the frame into a first strut and a second strut, wherein the left end of the first strut is connected with the rotating mechanism, and the right end is hinged with the left end of the second strut, when the rotating mechanism drives the When a rod rotates clockwise, the reel in the rotating mechanism simultaneously tightens the rope clockwise, so that the first rod and the second rod are relatively opened, thereby opening the flexible mask to open the sunshade device; When the rotating mechanism drives the first rod to rotate counterclockwise, the reel in the rotating mechanism simultaneously relaxes the pulling rope counterclockwise, and the second rod is automatically folded and folded under the action of gravity and the return coil spring; the length of the closed bracket is greatly shortened. Further, the entire opening and folding mechanism is driven by the pulling rope, and the reel is installed in the rotating mechanism. The structure is simple, ingenious, and has few accessories, which not only has low production cost, but also has smooth operation and low failure rate.

DRAWINGS

The present invention is further described below in conjunction with the accompanying drawings and embodiments:

Figure 1 is a schematic structural view of the present embodiment;

Fig. 2 is an enlarged view of a portion A of Fig. 1.

Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. It is a partial embodiment of the invention, and not all of the embodiments. The components of the embodiments of the invention, which are generally described and illustrated in the figures herein, may be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the invention in the claims All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

Referring to FIG. 1 and FIG. 2, a folding bracket applied to a backpack umbrella sunshade device according to the embodiment includes a rotating mechanism (1) and a bracket (2) connected to the rotating mechanism (1), the bracket (2) comprising a first strut (21) and a second strut (22), one end of the first strut (21) being fixedly coupled to the rotating mechanism, and the other end and one end of the second strut (22) Hinged, the other end of the second strut (22) is connected to an external flexible mask (3), and the second strut (22) is connected with a drawstring (4), the drawstring (4) It is connected to the reel (5) on the rotating mechanism (1) through the first strut (21). In the embodiment, the drawstring (4) is a steel wire rope, and has the advantages of small volume, large pulling force, and difficulty in breaking.

In a preferred embodiment, the first strut (21) and the second strut (22) are tubular, and the pull cord (4) extends through the first strut (21), the first strut (21) and the The joint between the two poles (22) is respectively provided with a male and female connector, one end of the female connector is sleeved at the end of the first pole (21), and the other end of the female connector is provided with an articulated shaft.
