Description

Technical Field

[0001] The utility model relates to the technical field of brackets, in particular to a folding bracket. Background Art

[0002] Folding brackets are popular because they can be folded to reduce their size and are easy to carry. They are widely used in outdoor sunshade devices, drying devices, folding traffic isolation racks, display devices, etc. Take sunshade devices as an example. Common sunshade devices, such as canopies, folding awnings, camping tents, etc., generally include sunshade cloth and folding brackets. The sunshade cloth is connected to the folding bracket to play the role of sunshade and windproof. While sunshade devices bring comfort to people's outdoor life, people have higher and higher requirements for the adaptability of folding brackets to the site, standing stability, and convenience of unfolding or folding operations.

[0003] The folding stand of the prior art, such as the patent application with publication number CN115559599A and titled "A portable folding stand" previously applied by the applicant of this case, includes a support frame of a first support rod and a second support rod, the top end of the first support rod and the top end of the second support rod are rotatably connected through a first hinge point; the first support rod and the second support rod are rotatably connected to each other through a rotating shaft, and the inner ends of the first support rod and the second support rod are rotatably connected through a second hinge point. When the first support rod and the second support rod rotate around the first hinge point to open or fold, the first support rod and the second support rod are synchronously rotated to open or fold. When the first support rod and the second support rod of the support frame are relatively rotated to open or fold, the positions of the first support rod and the second support rod on the support rod cannot slide along the axial direction of the support rod due to the limitation of the rotating shaft; this results in that when the support frame is unfolded, the first support rod and the second support rod are farther away from the top of the folding frame, thereby making the space below the folding frame smaller and limiting the unfolding distance between two adjacent support frames, and the overall unfolding length of the folding frame is smaller; accordingly, if a sunshade cloth is connected to the top of the folding frame, the sunshade cloth will be extended lower, and the sunshade area under the sunshade cloth will be smaller, which cannot meet the user's demand for a sunshade device with high extension and large sunshade area. Utility Model Content

[0004] The technical problem to be solved by the utility model is to overcome the defects of the above-mentioned prior art and provide a folding bracket which has a large space below when unfolded and is applied to a sunshade device so that the sunshade device has a higher extension and a larger sunshade area.

[0005] The technical solution of the utility model is to provide a folding bracket with the following structure:

[0006] Two groups of support frames, each group of support frames includes two support rods: a first support rod and a second support rod, the top end of the first support rod and the top end of the second support rod are rotatably connected through a first hinge point; the first support rod and the second support rod are respectively slidably connected with a sliding member that can slide along the length direction thereof, and the sliding members of the first support rod and the second support rod are respectively rotatably connected with a first support rod and a second support rod, and the inner ends of the first support rod and the second support rod are rotatably connected through a second hinge point;

[0007] A telescopic structure is arranged between two groups of support frames, and is used to make the two groups of support frames fold or unfold relative to each other; the first end of the telescopic structure is respectively hinged to the first hinge point and the second hinge point of one group of support frames, and the second end of the telescopic structure is respectively hinged to the first hinge point and the second hinge point of the other group of support frames.

[0008] After adopting the above structure, the folding bracket of the utility model has the following advantages compared with the prior art: the first support rod and the second support rod of each group of support frames of the folding bracket are rotatably connected through the first hinge point at the top, and the first support rod and the second support rod are both slidably connected with a sliding member, and the inner ends of the two support rods rotatably connected on the sliding member are rotatably connected through the second hinge point, so that a linkage rotation relationship is formed between the first support rod, the second support rod and the two support rods of each support frame; therefore, when the folding bracket is unfolded and used, it is only necessary to unfold the two groups of support frames, and the two ends of the telescopic structure respectively drive the second hinge points and the sliding members of the two groups of support frames to move in the direction close to the first hinge point, and at the same time, the first support rod, the second support rod and the support rod of the two groups of support frames are synchronously rotated and unfolded, so as to realize one-step unfolding, which is convenient for user operation; similarly, when the folding bracket is folded, it is only necessary to fold the two groups of support frames toward each other, and the two ends of the telescopic structure respectively drive the second hinge points and the sliding members of the two groups of support frames to move in the direction away from the first hinge point, and at the same time, the first support rod, the second support rod and the support rod of the two groups of support frames are synchronously rotated and folded, so as to realize one-step folding, which is further convenient for user operation. Moreover, by setting the sliding parts between the first support rod, the second support rod and the two support rods, when the folding bracket is unfolded, the sliding parts can drive the two support rods to a position closer to the first hinge point, so that the first support rod and the second support rod are closer to the top of the folding bracket, thereby making the top of the folding bracket extend higher and the distance between the two support frames larger, thereby making the space under the folding bracket larger; when a sunshade cloth is connected to the top of the folding bracket to be used as a sunshade, the sunshade cloth can be extended higher, there is more space under the sunshade cloth and the sunshade area is large.

[0009] In addition, when unfolded, the folding bracket can stand on its own with good standing stability and does not need to be fixed to the ground. It has low requirements for the installation site and has a wide range of uses. Furthermore, the overall structure is simple, light, and easy to carry, and the operation is simple and labor-saving. One person can easily unfold or fold the bracket, meeting the user's needs for quick unfolding or folding, and providing a good user experience. The user can also set the number of support frames according to needs, so that the length of the portable folding bracket can be adjusted. Therefore, whether it is personal use, family use or team use, it can be met and has a wide range of applications.

[0010] Preferably, the outer ends of the first support rod and the second support rod of each group of the support frame extend outward and extend out of the support frame to form a connection portion for connecting a sunshade. In this way, the connection portions of the two support rods can be connected to a sunshade, a tarpaulin, etc. When the support is folded or unfolded, the sunshade or tarpaulin folds or unfolds accordingly, and the sunshade or tarpaulin can be connected to the support at multiple points, thereby improving the firmness and wind resistance of the connection of the sunshade or tarpaulin. Furthermore, the sunshade or tarpaulin can be installed from the top of the support to the connection portion of the two support rods extending outward, thereby increasing the sunshade area.

[0011] Preferably, each group of the support frames further includes two pull rods respectively arranged in one-to-one correspondence with the first support rod and the second support rod, the upper ends of the two pull rods are respectively rotatably connected to the first hinge point, and the two pull rods are respectively hinged to the first support rod and the second support rod. The arrangement of the pull rods not only improves the stability and firmness of the top structure of the support frame, but also facilitates the installation of the sunshade or tarpaulin and provides more stable support for the sunshade or tarpaulin; the sunshade or tarpaulin can be connected to the pull rods, thereby increasing the area of ​​the sunshade or tarpaulin extending outward.

[0012] Preferably, each group of the support frames further includes a side rod and a top rod arranged on the outside of the support frames, the upper end of the side rod is hinged to the first hinge point of the support frame, one end of the top rod is hinged to the second hinge point of the support frame, and the other end of the top rod is hinged to the side rod. With this arrangement, the side rods of the two groups of support frames can allow the sunshade cloth installed on the top of the bracket to extend all the way to the side rods, thereby increasing the sunshade area and improving the connection firmness of the sunshade cloth. In addition, one end of the top rod is hinged to the second hinge point of the support frame, so that during the movement of the second hinge point, the side rod can be synchronously rotated to be folded or unfolded, thereby achieving synchronous folding or unfolding with the support frame.

[0013] Preferably, the telescopic structure comprises at least one telescopic assembly, and the telescopic assembly comprises two connecting rods with a middle hinged in an X shape: a first connecting rod and a second connecting rod, the upper ends of the first connecting rod and the second connecting rod are respectively hinged to the first hinge points of the two supporting frames, and the lower ends of the first connecting rod and the second connecting rod are respectively hinged to the second hinge points of the two supporting frames. When the telescopic assembly is unfolded, the lower ends of the first connecting rod and the second connecting rod simultaneously drive the second hinge points of the two supporting frames to move in a direction close to the first hinge point, thereby linking the two struts and the first support rod and the second support rod to rotate and unfold synchronously; and when the telescopic assembly is retracted, the lower ends of the first connecting rod and the second connecting rod simultaneously drive the second hinge points of the two supporting frames to move in a direction away from the first hinge point, thereby linking the two struts and the first support rod and the second support rod to rotate and fold synchronously. The setting of the telescopic structure not only makes the overall structure of the telescopic structure simple and light in overall weight, but also can link the two struts and the first support rod and the second support rod to rotate synchronously when the telescopic structure is unfolded or retracted, thereby realizing one-step folding or one-step unfolding.

[0026] The utility model is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] Embodiment 1:

[0028] See also Figures 1-2 As shown;

[0029] The utility model embodiment discloses a folding bracket, which is applied to a canopy, a folding awning, a camping tent, a clothes drying rack, a folding traffic isolation rack, a display rack, etc. The folding bracket has a structure comprising two groups of support frames 1, each group of support frames 1 comprising two support rods: a first support rod 100 and a second support rod 101, the top of the first support rod 100 and the top of the second support rod 101 are rotatably connected through a first hinge point 3; the first support rod 100 and the second support rod 101 are respectively slidably connected with a sliding member 5 that can slide along the length direction thereof, and the sliding members 5 of the first support rod 100 and the second support rod 101 are respectively rotatably connected with a first support rod 102 and a second support rod 108, and the inner ends of the first support rod 102 and the second support rod 108 are rotatably connected through a second hinge point 4; in this embodiment, the first support rod 100 and the second support rod 101 are both configured as axially retractable telescopic tubes, and a locking screw or a lock buckle can be connected between the inner and outer tubes of the telescopic tube to maintain the unfolded state of the inner and outer tubes. The sliding member 5 described in this embodiment is a sliding sleeve mounted on the first support rod 100 and the second support rod 101. In other embodiments, a sliding groove can also be set in the length direction of the first support rod 100 and the second support rod 101, and the sliding member is a slider slidably fitted in the sliding groove.

[0030] In addition, the rotatable connection or hinge described in this embodiment can be a rotatable connection or hinge through a hinge pin, a swivel joint, a rotating shaft, a hinge, a universal joint, etc.; wherein, the first hinge point 3 and the second hinge point 4 in the utility model are connecting parts such as an articulated seat and a connecting plate, and the connecting part has multiple connecting ends, each of which is connected to a rotating shaft. Taking the first hinge point 3 as an example, the first hinge point 3 has six connecting ends, and the upper ends of the first support rod 100 and the second support rod 101 are respectively located on both sides of the first hinge point 3, and are both rotatably connected to the connecting ends of the first hinge point 3 through the rotating shaft; when the first support rod 100 is rotated to be folded or unfolded relative to the second support rod 101, the first support rod 102 and the second support rod 108 are linked to be rotated to be folded or unfolded. In this embodiment, the projections of the first hinge point 3 and the second hinge point 4 of each group of support frames 1 in the vertical direction coincide. In this way, the first support rod 102 and the second support rod 108 are both extended obliquely upward, which obliquely supports the corners of the sunshade cloth or tarpaulin, and the forces on the four sides of the sunshade cloth or tarpaulin are more balanced, which also enhances the stability and wind resistance.

[0031] See again Figure 1As shown, in the present embodiment, the number of the support frames 1 is two, while in other embodiments, the number of the support frames 1 may be three, four, five, etc., and the number of the support frames 1 may be set specifically according to the overall length of the folding bracket and the needs of the user.

[0032] See again Figure 1 As shown, in this embodiment, a telescopic structure 2 is provided between the two groups of support frames 1, and the telescopic structure 2 is used to make the two groups of support frames 1 relatively folded or unfolded; specifically, the first end of the telescopic structure 2 is respectively hinged to the first hinge point 3 and the second hinge point 4 of one group of support frames 1, and the second end of the telescopic structure 2 is respectively hinged to the first hinge point 3 and the second hinge point 4 of the other group of support frames 1; wherein, when the two groups of support frames 1 are relatively folded, the two ends of the telescopic structure 2 respectively drive the second hinge point 4 and the sliding member 5 of the two groups of support frames 1 to move in the direction away from the first hinge point 3, and at the same time, the first support rod 100, the second support rod 101 and the first support rod 102 and the second support rod 108 of the two groups of support frames 1 are synchronously rotated and folded; when the two groups of support frames 1 are relatively unfolded, the two ends of the telescopic structure 2 respectively drive the second hinge point 4 and the sliding member 5 of the two groups of support frames 1 to move in the direction close to the first hinge point 3, and at the same time, the first support rod 100, the second support rod 101 and the first support rod 102 and the second support rod 108 of the two groups of support frames 1 are synchronously rotated and unfolded.

[0033] See again Figure 1 and Figure 2As shown, in this embodiment, the first support rod 100 and the second support rod 101 of each group of support frames 1 of the folding bracket are rotatably connected through the first hinge point 3 at the top, and the first support rod 100 and the second support rod 101 are slidably connected with a sliding member 5, and the inner ends of the two support rods rotatably connected on the sliding member 5 are rotatably connected through the second hinge point 4, so a linkage rotation relationship is formed between the first support rod 100, the second support rod 101 and the two support rods of each support frame 1; therefore, when the folding bracket is unfolded and used, it is only necessary to unfold the two groups of support frames 1, and the two ends of the telescopic structure 2 respectively drive the second hinge points 4 and the sliding members 5 of the two groups of support frames 1 to approach The first hinge point 3 moves in the direction of the first hinge point 3, and at the same time, the first support rod 100, the second support rod 101, the first support rod 102 and the second support rod 108 of the two groups of support frames 1 are linked to rotate and unfold synchronously, so as to realize one-step unfolding, which is convenient for user operation; similarly, when the folding bracket is folded, it is only necessary to fold the two groups of support frames 1 toward each other, and the two ends of the telescopic structure 2 respectively drive the second hinge points 4 and the sliding members 5 of the two groups of support frames 1 to move in the direction away from the first hinge point 3, and at the same time, the first support rod 100, the second support rod 101, the first support rod 102 and the second support rod 108 of the two groups of support frames 1 are linked to rotate and fold synchronously, so as to realize one-step folding, which is further convenient for user operation. Moreover, by setting the sliding member 5 between the first support rod 100, the second support rod 101 and the first support rod 102 and the second support rod 108, when the folding bracket is unfolded, the sliding member 5 can drive the two support rods 102 to a position closer to the first hinge point 3, so that the top of the folding bracket can be extended higher and the distance between the two support frames can be larger, thereby making the space under the folding bracket larger; when a sunshade cloth is connected to the top of the folding bracket to be used as an awning, there is a larger space under the awning and the shading area is large.

[0034] The overhang in the present invention refers to the distance from the edge of the sunshade cloth to the ground when the folding bracket is unfolded. When the folding bracket is unfolded, the higher the distance from the edge of the sunshade cloth to the ground, the higher the overhang, and the smaller the distance from the edge of the sunshade cloth to the top of the folding bracket; conversely, the greater the distance from the edge of the sunshade cloth to the top of the folding bracket, the smaller the distance from the edge of the sunshade cloth to the ground, and the smaller the overhang.

[0035] The folding bracket of the present embodiment can stand on its own when unfolded, and has good standing stability and does not need to be fixed to the ground, so the requirements for the installation site are low and the scope of use is wide. Furthermore, the overall structure is simple, light, and easy to carry, and the operation is simple and labor-saving. One person can easily unfold or fold the bracket, meeting the user's needs for quick unfolding or folding, and the user experience is good. The user can also set the number of support frames according to needs, so that the length of the portable folding bracket can be adjusted. Therefore, whether it is personal use, family use or team use, it can be met and has a wide range of applications.

[0036] See again Figure 1 and Figure 2 As shown, in this embodiment, the outer ends of the first support rod 102 and the second support rod 108 of each group of support frames 1 extend outward and extend out of the support frame 1 to form a connection portion for connecting the sunshade cloth. Specifically, each group of the support frames 1 also includes two pull rods 103 respectively corresponding to the first support rod 102 and the second support rod 108, the upper ends of the two pull rods 103 are rotatably connected to the first hinge point 3, and the two pull rods 103 are respectively hinged to the first support rod 102 and the second support rod 108; the connection portion of the first support rod 102 and the second support rod 108 can be connected to the sunshade cloth, tarpaulin, etc. When the support is folded or unfolded, the sunshade cloth or tarpaulin is folded or unfolded accordingly, and the sunshade cloth or tarpaulin can be connected to the support at multiple points, thereby improving the firmness and wind resistance of the connection of the sunshade cloth or tarpaulin. Furthermore, the sunshade cloth or tarpaulin can be installed from the top of the support to the connection portion of the two support rods extending outward, thereby increasing the shading area. The further setting of the pull rod 103 not only improves the stability and firmness of the top structure of the support frame 1, but also facilitates the installation of the sunshade cloth or tarpaulin and provides more stable support for the sunshade cloth or tarpaulin; the sunshade cloth or tarpaulin can be connected to the pull rod 103, thereby increasing the area of ​​the sunshade cloth or tarpaulin extending outward.

[0037] See again Figure 1 and Figure 2 As shown, in this embodiment, each group of support frames 1 further includes a side bar 106 and a top bar 107 arranged on the outside of the support frame 1, the upper end of the side bar 106 is hinged to the first hinge point 3 of the support frame 1, one end of the top bar 107 is hinged to the second hinge point 4 of the support frame 1, and the other end of the top bar 107 is hinged to the side bar 106. The side bars 106 of the two groups of support frames 1 can make the sunshade cloth installed on the top of the bracket extend all the way to the side bars 106, thereby increasing the sunshade area and improving the connection firmness of the sunshade cloth. In addition, one end of the top bar 107 is hinged to the second hinge point 4 of the support frame 1, so during the movement of the second hinge point 4, the side bar 106 can be rotated synchronously to be folded or unfolded, so as to achieve synchronous folding or unfolding with the support frame 1.

[0038] See again Figure 1As shown, in this embodiment, the telescopic structure 2 includes at least one group of telescopic components 200, and the telescopic components 200 include two connecting rods hinged in the middle to form an X shape: a first connecting rod 201 and a second connecting rod 202, the upper ends of the first connecting rod 201 and the second connecting rod 202 are respectively hinged to the first hinge points 3 of the two groups of support frames 1, and the lower ends of the first connecting rod 201 and the second connecting rod 202 are respectively hinged to the second hinge points 4 of the two groups of support frames 1. In this embodiment, the telescopic components 200 are divided into two groups and are distributed in sequence along the telescopic direction of the telescopic mechanism. The upper end of the first connecting rod 201 of the first group of telescopic components is hinged to the first hinge point 3 of the first group of support frame 1, the lower end of the second connecting rod 202 of the first group of telescopic components is hinged to the second hinge point 4 of the first group of support frame 1, the lower end of the first connecting rod 201 of the first group of telescopic components is hinged to the lower end of the second connecting rod 202 of the second group of telescopic components through the fourth hinge point 8, the upper end of the second connecting rod 202 of the first group of telescopic components is hinged to the upper end of the first connecting rod 201 of the second group of telescopic components through the third hinge point 7, the lower end of the first connecting rod 201 of the second group of telescopic components 200 is hinged to the second hinge point 4 of the second group of support frame 1, and the upper end of the second connecting rod 202 of the second group of telescopic components 200 is hinged to the first hinge point 3 of the second group of support frame 1.

[0039] When the telescopic assembly 200 is unfolded, the lower ends of the first connecting rod 201 and the second connecting rod 202 simultaneously drive the second hinge points 4 of the two groups of support frames 1 to move in a direction close to the first hinge point 3, thereby linking the two struts and the first support rod 100 and the second support rod 101 to rotate and unfold synchronously; and when the telescopic assembly 200 is retracted, the lower ends of the first connecting rod 201 and the second connecting rod 202 simultaneously drive the second hinge points 4 of the two groups of support frames 1 to move in a direction away from the first hinge point 3, thereby linking the two struts 102 and the first support rod 100 and the second support rod 101 to rotate and fold synchronously. The setting of the telescopic structure 2 not only makes the overall structure of the telescopic structure 2 simple and the overall weight light, but also can link the two struts and the first support rod 100 and the second support rod 101 to rotate synchronously when the telescopic structure 2 is unfolded or retracted, thereby realizing one-step folding or one-step unfolding. Likewise, when the telescopic assembly 200 is unfolded, the fourth hinge point 8 moves toward the direction approaching the third hinge point 7 , and when the telescopic assembly 200 is retracted, the fourth hinge point 8 moves toward the direction away from the third hinge point 7 .

[0040] See again Figure 1As shown, in this embodiment, the first support rod 203 and the second support rod 204 are respectively provided on both sides of the telescopic structure 2, one end of the first support rod 203 is hinged to the third hinge point 7, one end of the second support rod 204 is hinged to the fourth hinge point 8, and the other end of the second support rod 204 is hinged to the first support rod 203. The arrangement of the first support rod 203 and the second support rod 204 facilitates the installation of the sunshade cloth or tarpaulin on the first support rod 203, and provides more stable support for the sunshade cloth or tarpaulin. At the same time, the first support rod 203 and the second support rod 204 can be synchronously contracted or unfolded with the contraction or unfolding of the telescopic structure 2, so as to realize the one-step folding or one-step unfolding of the folding bracket, and the operation is very convenient.

[0041] See again Figure 1 and Figure 2 As shown, a locking mechanism 6 is connected between the first hinge point 3 and the second hinge point 4 of the support frame 1 or / and between the third hinge point 7 and the fourth hinge point 8 of the telescopic structure 2 to keep the support frame 1 in the unfolded state. In this embodiment, the locking mechanism 6 can be a locking rod or a locking rope. For example, a vertically arranged locking rod is connected to the center of the first hinge point 3, and a locking hole for the locking rod to pass through is arranged at the center of the second hinge point 4. When the support is in the unfolded state, the locking rod is inserted into the locking hole and locked. The locking can be locked by screws, or an elastic locking pin is arranged on the locking rod, and a limiting hole for the elastic locking pin to be inserted is arranged in the locking hole; or a downwardly arranged locking rope is connected to the center of the first hinge point 3. When the support is in the unfolded state, the locking rope knots the second hinge point 4 to fix it. This locking structure is a common locking structure in the prior art, and this embodiment will not be described in detail. The setting of the locking structure keeps the support stable when the folding support is unfolded, avoids automatic folding due to accidental touch, and has good safety.
