Description

Technical Field

[0001] This utility model relates to the field of bracket technology, and in particular to a suspension bracket. Background Technology

[0002] Rope pullers are typically fixed by suspending them from fixed supports or other building structures. However, they are not easy to install during use, and people who are not tall enough need to climb ladders or other auxiliary equipment to hang them. Improper installation or loose suspension points can cause the rope puller and other equipment to fall, damaging the equipment and endangering personal safety. Furthermore, current fixed supports are usually made by welding or riveting, which makes them bulky and inconvenient to store and transport. Utility Model Content

[0003] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a suspension bracket that can be adjusted in size, facilitating storage, transportation, and operation.

[0004] A suspension bracket according to an embodiment of the present invention includes a suspension base and a plurality of telescopic rod assemblies. The suspension base has a centerline parallel to the direction of gravity. A lifting lug is provided on the suspension base at the position of the centerline. A plurality of limiting blocks are provided on the suspension base, and each of the limiting blocks has a limiting surface. The multiple limiting surfaces are rotationally symmetrically distributed with respect to the centerline of the suspension base. The normal direction of each limiting surface forms the same inclination angle with the direction of gravity. The vertical distance between the lower side of the limiting surface and the centerline of the suspension base is greater than the vertical distance between the upper side of the limiting surface and the centerline of the suspension base. The distance; the number of telescopic rod assemblies is equal to the number of limiting blocks. Multiple telescopic rod assemblies are respectively arranged opposite to multiple limiting blocks. The upper end of each telescopic rod assembly is hinged to the suspension seat via a first hinge pin. Multiple first hinge pins are distributed in a plane perpendicular to the centerline of the suspension seat. The first hinge pins are parallel to the limiting surfaces on the opposite limiting blocks. The outer surface of the telescopic rod assembly above the first hinge pin can abut against the limiting surface. The limiting surface limits the angle at which the lower end of the telescopic rod assembly swings outward, so that the suspension seat and the telescopic rod assembly are relatively fixed.

[0005] It has at least the following beneficial effects: the lower ends of the multiple telescopic rod assemblies all swing outwards, and the lower ends of the telescopic rod assemblies abut against the ground or other supporting platforms. Under the action of gravity, the outer surface of the telescopic rod assembly above the first hinge pin abuts against the limiting surface. Force points are formed between the outer surface of the telescopic rod assembly above the first hinge pin and the limiting surface, and between the suspension seat and the first hinge pin, thus supporting the suspension seat. Tools such as rope pullers or heavy objects can be hung on the lifting lugs first, and then the telescopic rod assembly can be extended until the suspension seat and the tools or heavy objects rise to a suitable height. Alternatively, the telescopic rod assembly can be extended first to raise the suspension seat and lifting lugs to a suitable height, and then the tools or heavy objects can be hung on the lifting lugs. The telescopic rod assembly can extend and retract to change its length, thereby adjusting the height of the suspension seat, lifting lugs, and the tools or heavy objects suspended on the lifting lugs. When the suspension bracket is not in use, the telescopic rod assembly is shortened, and the lower ends of multiple telescopic rod assemblies swing inward and move closer to each other, reducing the volume of the suspension bracket, making it easy to store and transport, and the operation method is simple.

One limiting block is disposed between a pair of ear plates. All ear plates are parallel to the direction of gravity. The upper end of the telescopic rod assembly is hinged to a pair of ear plates on the suspension seat through the first hinge shaft.

[0011] According to some embodiments of the present invention, the suspension seat includes a central frame and three horizontal bars. The three horizontal bars are connected end to end to form an equilateral triangle structure. The central frame is located at the center of the equilateral triangle structure. The central frame is connected to the middle of the three horizontal bars through three connecting rods. The middle of the central frame is connected to the lifting lug. The three corners of the equilateral triangle structure are respectively connected to the three limiting blocks.

[0012] According to some embodiments of this utility model, it also includes a bolt and a nut. The lifting lug includes an annular portion and a U-shaped portion. Both ends of the U-shaped portion are connected to the outer wall of the annular portion through a third hinge axis. The third hinge axis is perpendicular to the direction of gravity. The annular portion is provided with a central hole. The opening of the U-shaped portion is located directly below the central hole. A first connecting hole is provided at the center of the central frame. The central axis of the first connecting hole is the center line of the suspension seat. The threaded section of the bolt passes through the central hole and the first connecting hole from bottom to top, and the threaded section is threadedly connected to the nut. The nut abuts against the upper surface of the central frame, and the end cap of the bolt abuts against the lower surface of the annular portion.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0018] In the description of this utility model, the use of "first" and "second" is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of technical features indicated, or implicitly indicating the order of the technical features indicated.

[0019] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0020] Reference Figures 1 to 4This utility model discloses a suspension bracket, including a suspension seat 1 and multiple telescopic rod assemblies 4. The suspension seat 1 has a centerline parallel to the direction of gravity. A lug 2 is provided on the suspension seat 1 at the position of the centerline, used to suspend tools such as rope pullers or heavy objects. Multiple limiting blocks 3 are provided on the suspension seat 1, circumferentially distributed based on the centerline of the suspension seat 1. The central angles corresponding to any two adjacent limiting blocks 3 are equal. The distances between the multiple limiting blocks 3 and the centerline of the suspension seat 1 are equal. The planes on which the multiple limiting blocks 3 are located are perpendicular to the centerline of the suspension seat 1. Each of the multiple limiting blocks 3 has a limiting surface 31, which is rotationally symmetrically distributed with respect to the centerline of the suspension seat 1. The normal force of each limiting surface 31 is... The linear direction forms the same tilt angle as the direction of gravity. The vertical distance between the lower side of the limiting surface 31 and the center line of the suspension seat 1 is greater than the vertical distance between the upper side of the limiting surface 31 and the center line of the suspension seat 1. The number of telescopic rod assemblies 4 is equal to the number of limiting blocks 3. Multiple telescopic rod assemblies 4 are respectively arranged opposite to multiple limiting blocks 3. The upper end of the telescopic rod assembly 4 is hinged to the suspension seat 1 through a first hinge pin 5. Multiple first hinge pins 5 are distributed in a plane perpendicular to the center line of the suspension seat 1. The first hinge pins 5 and the limiting surfaces 31 on the opposite limiting blocks 3 are parallel to each other. The outer surface of the telescopic rod assembly 4 above the first hinge pin 5 can abut against the limiting surface 31. The limiting surface 31 limits the angle at which the lower end of the telescopic rod assembly 4 swings outward (e.g., Figure 3 (as shown in the inward and outward directions) to fix the suspension seat 1 and the telescopic rod assembly 4 relative to each other.

[0021] The lower ends of multiple telescopic rod assemblies 4 all swing outwards, with the lower ends of the telescopic rod assemblies 4 resting against the ground or other supporting platforms. Under the action of gravity, the outer surface of the telescopic rod assembly 4 above the first hinge pin 5 rests against the limiting surface 31. Force points are formed between the outer surface of the telescopic rod assembly 4 above the first hinge pin 5 and the limiting surface 31, and between the suspension seat 1 and the first hinge pin 5, thus supporting the suspension seat 1. Tools such as rope pullers or heavy objects can be hung on the lifting lugs 2 first, and then the telescopic rod assembly 4 can be extended until the suspension seat 1 and the tools or heavy objects rise to a suitable height. Alternatively, the telescopic rod assembly 4 can be extended first to raise the suspension seat 1 and the lifting lugs 2 to a suitable height, and then the tools or heavy objects can be hung on the lifting lugs 2. The telescopic rod assembly 4 can extend and retract to change its length, thereby adjusting the height of the suspension seat 1, the lifting lugs 2, and the tools or heavy objects suspended on the lifting lugs 2. When the suspension bracket is not in use, the telescopic rod assembly 4 is shortened, and the lower ends of multiple telescopic rod assemblies 4 all swing inward and move closer to each other (e.g., Figure 5 (As shown in the diagram), the size of the suspension bracket is reduced, making it easier to store and transport, and the operation method is simple.

[0022] Understandably, the height of the first hinge 5 is close to the lower edge of the limiting surface 31, so that when the lower ends of the multiple telescopic rod assemblies 4 swing inward, the lower side of the limiting surface 31 avoids interference with the lower end of the telescopic rod assembly 4.

[0023] In this embodiment, the cross-section of the suspension seat 1 is an equilateral triangle. The suspension seat 1 has three corners. There are three limiting blocks 3 and three telescopic rod assemblies 4. The three limiting blocks 3 are respectively located at the three corners of the suspension seat 1. The three telescopic rod assemblies 4 are respectively hinged to the three corners of the suspension seat 1 through three first hinge shafts 5.

[0024] In some of these embodiments, reference is made to Figure 4 The tilt angle is α, 100°≤α≤120°. When the lower ends of multiple telescopic rod assemblies 4 all swing outward, the diameter of the circle formed by the lower ends of multiple telescopic rod assemblies 4 is more appropriate. Avoid the circle diameter being too small or too large. If the circle diameter is too small, the operating space under the suspension seat 1 will be too small. If the circle diameter is too large, the area occupied by the suspension bracket will be too large.

[0025] In this embodiment, the tilt angle is 103°.

[0026] Reference Figure 4 In some embodiments, the upper end of the telescopic rod assembly 4 is provided with an abutment surface 41, which is parallel to the first hinge shaft 5 on the corresponding telescopic rod assembly 4. The abutment surface 41 can fit against the limiting surface 31, so that the contact surface between the limiting block 3 and the telescopic rod assembly 4 is large enough to increase the load capacity of the suspension bracket.

[0027] Reference Figure 3 In some embodiments, the suspension bracket further includes multiple foot pads 6, which are hinged to the lower end of the telescopic rod assembly 4 via multiple second hinge pins 7. The first hinge pin 5 and the second hinge pin 7 on the same telescopic rod assembly 4 are parallel to each other. The foot pads 6 can rotate relative to the lower end of the telescopic rod assembly 4, so that when the telescopic rod assembly 4 is at different tilt angles, the lower surface of the foot pads 6 can be parallel to the ground or other support platform, ensuring the contact area between the foot pads 6 and the ground or other support platform, thereby ensuring the load-bearing capacity of the foot pads 6.

[0028] In some embodiments, the telescopic rod assembly 4 has a rectangular cross-section and a first hinge hole that penetrates two parallel sides of the telescopic rod assembly 4. (Refer to...) Figure 1 or Figure 5 The foot pad 6 is U-shaped, and each of its two parallel ends has a second hinge hole. The two second hinge holes are coaxially arranged, as shown in the reference. Figure 3The second hinge pin 7 is sequentially inserted through a second hinge hole, a first hinge hole, and another second hinge hole to hinge the telescopic rod assembly 4 to the foot pad 6. The foot pad 6 is U-shaped, so that two hinge points are formed between the telescopic rod assembly 4 and the foot pad 6, thereby enabling the telescopic rod assembly 4 and the foot pad 6 to have a large load-bearing capacity.

[0029] Reference Figure 1 or Figure 2 In some embodiments, the suspension seat 1 is provided with multiple pairs of ear plates 13. Each pair of ear plates 13 includes two parallel ear plates 13. The multiple pairs of ear plates 13 are arranged opposite to multiple limiting blocks 3. One limiting block 3 is located between a pair of ear plates 13. All ear plates 13 are parallel to the direction of gravity. (Refer to...) Figure 4 The upper end of the telescopic rod assembly 4 is hinged to a pair of ear plates 13 on the suspension seat 1 via the first hinge pin 5.

[0030] The telescopic rod assembly 4 is provided with a third hinge hole, and both ear plates 13 are provided with a fourth hinge hole. The first hinge shaft 5 is sequentially inserted through one fourth hinge hole, the third hinge hole and the other fourth hinge hole to achieve the hinge connection between the telescopic rod assembly 4 and the pair of ear plates 13.

[0031] Reference Figure 3 In some embodiments, the telescopic rod assembly 4 includes an upper rod, a lower rod, and an adjusting rod. The upper rod is provided with a plurality of first adjusting holes distributed along the length direction of the upper rod, and the lower rod is provided with a plurality of second adjusting holes distributed along the length direction of the lower rod. The adjusting rod can pass through different first adjusting holes and different second adjusting holes to adjust the length of the telescopic rod assembly 4.

[0032] It is conceivable that both the upper and lower rods are square tubes, each with an inner hole that penetrates the upper and lower end faces of the upper / lower rod. The lower end of the upper rod passes through the inner hole at the upper end of the lower rod, or the upper end of the lower rod passes through the lower end of the upper rod. Of course, the upper and lower rods can also be arranged in a staggered manner in the horizontal direction.

[0033] Reference Figure 6 In some embodiments, the suspension seat 1 includes a central frame and three crossbars 11. The three crossbars 11 are connected end to end to form an equilateral triangle structure. The central frame is located at the center of the equilateral triangle structure. The central frame is connected to the middle of the three crossbars 11 through three connecting rods 12 to form a compact and load-bearing overall structure. The middle of the central frame is connected to the lug 2. The three corners of the equilateral triangle structure are respectively connected to three limiting blocks 3, so that the suspension seat 1 is balanced by force.

[0034] In some embodiments, the suspension bracket further includes a connector, see reference Figure 7 The end face of one end of the connecting rod 12 is provided with a second connecting hole 121, as shown in the reference. Figure 6The crossbar 11 has a third connecting hole 111 in the middle. Both the second connecting hole 121 and the third connecting hole 111 are perpendicular to the direction of gravity. Figure 8 The connector passes through the third connecting hole 111 and the second connecting hole 121 to connect the connecting rod 12 and the crossbar 11 together, so as to realize the detachable connection of the connecting rod 12 and the crossbar 11. Of course, the connecting rod 12 and the crossbar 11 can also be connected by welding.

[0035] In some of these embodiments, reference is made to Figure 7 The suspension bracket also includes bolts 8 and nuts 9. The lifting lug 2 includes an annular part 21 and a U-shaped part 22. The U-shaped part 22 is used to hang tools such as drawstrings or heavy objects. Both ends of the U-shaped part 22 are connected to the outer wall of the annular part 21 through a third hinge 23. The third hinge 23 is perpendicular to the direction of gravity. The annular part 21 is provided with a central hole. The opening of the U-shaped part 22 is located directly below the central hole, so that the U-shaped part 22 can rotate around the third hinge 23, thereby allowing tools such as drawstrings or heavy objects to swing.

[0036] The center of the central frame is provided with a first connecting hole. The central axis of the first connecting hole is the center line of the suspension seat 1. The threaded section of the bolt 8 passes through the central hole and the first connecting hole from bottom to top, and the threaded section is threadedly connected to the nut 9. The nut 9 abuts against the upper surface of the central frame, and the end cap of the bolt 8 abuts against the lower surface of the annular part 21, thereby connecting the central frame and the annular part 21 together. The annular part 21 can rotate on the central frame, that is, the U-shaped part 22 and the tools or weights such as the drawstring on the U-shaped part 22 can rotate around the direction of gravity.

[0037] It should be noted that the direction of gravity is parallel to the up and down direction, and the normal direction of the limiting surface 31 refers to the direction of the vertical line perpendicular to the limiting surface 31 from inside the limiting surface 31 to outside the limiting surface 31.

[0038] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0039] Of course, this utility model is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
