Description

Technical Field

[0001] This utility model relates to the field of support technology, specifically to a folding support. Background Technology

[0002] As outdoor barbecues become more popular, the demand for outdoor barbecue equipment is also increasing, requiring a portable and easy-to-store stand for barbecuing.

[0003] Existing foldable barbecue racks are connected by hinges between the frame and the legs, and the rack can be switched between unfolded and folded states by rotating some of the legs.

[0004] However, existing folding brackets pose a risk of pinching hands and have safety issues. Utility Model Content

[0005] This utility model aims to solve one of the technical problems in related technologies to a certain extent. To this end, this utility model provides a folding bracket, which has the advantages of avoiding the risk of fingers being pinched during use and improving safety.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A folding bracket includes a top plate and a scissor support assembly. The scissor support assembly includes a first leg and a second leg hinged to each other. The top end of the first leg is hinged to the back of the top plate. The folding bracket also includes a protective beam. The second leg includes a synchronizing rod and a plurality of support rods. The support rods are hinged to the first leg, and the synchronizing rod is connected to the top ends of the plurality of support rods. The protective beam is spaced apart on the back of the top plate, and both ends of the protective beam are fixed to both ends of the top plate. There is a movable gap between the protective beam and the top plate. The synchronizing rod passes through the movable gap and is capable of sliding along the protective beam. The first and second legs of the scissor lift support assembly are hinged together, enabling the rotation of the scissor lift support unit and allowing the scissor lift support assembly to be stored. In this embodiment, the top of the first leg is fixed to the back of the top plate, and the folding bracket is folded up and unfolded by rotating the second leg. A synchronizing rod is provided at the top of the second leg to ensure the synchronous rotation of the multiple support rods of the second leg. During the process of the folding bracket changing from folded up to unfolded, in order to prevent safety risks caused by the gap between the second leg and the top plate during rotation, a protective beam is provided on the back of the top plate. The protective beam limits the range of motion of the synchronizing rod, ensuring that the synchronizing rod is within the movement interval between the protective beam and the top plate, thereby ensuring that the gap between the second leg and the top plate is not easy to pinch hands, improving safety during use.

[0007] Optionally, the protective beam includes a limiting rod and two mounting components. The two mounting components are located at both ends of the limiting rod and fixed to the back of the top plate. There is a movement gap between the limiting rod and the top plate, and the synchronizing rod can slide along the limiting rod. The mounting components are used to fix the protective beam to the back of the top plate. Since a gap is required between the limiting rod and the top plate to accommodate the sliding of the synchronizing rod, a single mounting component cannot meet the requirements. Therefore, two mounting components are provided to complete the fixation of the limiting rod to the top plate, thereby improving the structural stability of the protective beam.

[0008] Optionally, the folding bracket further includes a snap-fit ​​element that passes through the moving interval and is located on the back of the top plate. The snap-fit ​​element and the hinge point of the first leg on the top plate are respectively located on both sides of the top plate. The hinge point of the first leg on the top plate is located at the first end of the back of the top plate, and the snap-fit ​​element is located at the second end of the back of the top plate. This can fix the second leg by preventing the movement of the synchronizing rod, thereby fixing the folding bracket and improving the stability of the folding bracket when unfolded.

[0009] Optionally, the snap-fit ​​component includes a connecting portion and a bending portion. The connecting portion is fixedly connected to the top plate. One end of the bending portion is fixed to the connecting portion, and the other end extends and bends away from the top plate. The bending portion and the connecting portion form a fixing groove, which is used to accommodate the scissor support assembly and snaps into it when the folding bracket is unfolded. The synchronizing rod is snapped into and fixed by the snap-fit ​​component when the folding bracket is unfolded. The snap-fit ​​component is used to snap into the synchronizing rod when the folding bracket is unfolded. The connecting portion of the snap-fit ​​component is fixedly connected to the top plate, and the bending portion is away from the top plate and forms a fixing groove with the connecting portion. When the folding bracket is unfolded, the synchronizing rod moves into the fixing groove and abuts against the inner wall of the fixing groove. The fixing groove can prevent the synchronizing rod from sliding out of the moving interval, thus improving the stability of the folding bracket.

[0010] Optionally, the second leg further includes a fixing member, and the synchronizing rod is fixed to the top of the support rod; the first leg has a fixing hole, and the support rod has a hinge hole, through which the fixing member can pass and be fixed in the fixing hole, and the second leg can rotate relative to the first leg around the fixing member. The first and second legs are hinged together, so that when the folding bracket is folded up, the angle between the first and second legs becomes 0°, i.e., the first and second legs rotate and overlap, which improves the folding bracket's storage capacity. The maximum distance between the two support rods of the second leg is less than the maximum distance between the two legs of the first leg. When folded up, the second leg rotates into the interior of the first leg and is covered by it, improving both storage capacity and aesthetics.

[0011] Optionally, when the folding bracket is folded up, the synchronizing rod is close to the first end of the top plate; when the folding bracket is unfolded, the synchronizing rod is close to the second end of the top plate, the synchronizing rod is located in the fixing groove, and is engaged and fixed with the bending part.

[0012] Optionally, the bending portion includes a snap-fit ​​unit and a connecting unit. One end of the connecting unit is fixedly connected to the connecting portion, and the other end of the connecting unit is fixed to the snap-fit ​​unit. The snap-fit ​​unit is parallel to the top plate and extends toward the top plate at the end away from the connecting unit to form a blocking unit. The minimum distance between the blocking unit and the top plate is less than the minimum distance between the snap-fit ​​unit and the top plate. When the folding bracket is unfolded, the synchronizing rod is in close contact with the connecting unit, and the blocking unit is used to prevent the synchronizing rod from leaving the fixing groove.

[0013] Optionally, a handle is provided at the first end of the top plate. The handle is used to pull the folding bracket, which can reduce the difficulty of use and transportation.

[0014] Optionally, the first support leg further includes a caster wheel, which is disposed at the second end of the first support leg, with the edge of the caster wheel extending beyond the first support leg. The caster wheel can reduce the difficulty of movement when the folding bracket is folded up, facilitating transportation.

[0015] Optionally, when the folding bracket is unfolded, the handle is at the same height from the ground as the top plate; when the folding bracket is folded up, the second end of the handle relative to the top plate is away from the caster. By setting the handle position, the handle is separated from the bottom of the bracket when the folding bracket is unfolded, keeping the handle away from the bottom of the bracket. This prevents wear and tear on the handle due to prolonged contact with dirt or other environmental factors during use, improving the handle's safety and cleanliness, and eliminating the need to clean the handle every time it is folded up.

[0016] The technical solution of this application has the following beneficial effects: preventing safety problems such as pinching hands during use, reducing wear on the handle, reducing the need for cleaning, and making the handle cleaner.

[0022] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described are intended to explain this utility model and should not be construed as limiting it.

[0023] The terms "an embodiment," "example," or "trademark" used in this specification refer to a particular feature, structure, or characteristic described in connection with the embodiment itself that may be included in at least one embodiment disclosed in this utility model. The phrase "in one embodiment" appearing in various places throughout the specification does not necessarily refer to the same embodiment.

[0024] Example: like Figure 1As shown, a folding bracket includes a top plate 1 and a scissor support assembly 2. The scissor support assembly 2 includes a first leg 21 and a second leg 22 hinged to each other. The top end of the first leg 21 is hinged to the back of the top plate 1. The folding bracket also includes a protective beam 3. The second leg 22 includes a synchronizing rod 221 and a plurality of support rods 222. The support rods 222 are hinged to the first leg 21, and the synchronizing rod 221 is connected to the top ends of the plurality of support rods 222. The protective beams 3 are spaced apart on the back of the top plate 1, and the two ends of the protective beams 3 are fixed to the two ends of the top plate 1. There is a movable gap between the protective beams 3 and the top plate 1. The synchronizing rods 221 pass through the movable gap and can slide along the protective beams 3. The first leg 21 and the second leg 22 of the scissor support assembly 2 are hinged together to enable the rotation of the scissor support unit and to retract the scissor support assembly 2. In this embodiment, the top of the first leg 21 is fixed to the back of the top plate 1. The folding bracket is retracted and unfolded by the rotation of the second leg 22. A synchronizing rod 221 is provided at the top of the second leg 22 to ensure the synchronous rotation of the multiple support rods 222 of the second leg 22. During the process of the folding bracket changing from retracted to unfolded, in order to prevent the gap between the second leg 22 and the top plate 1 from causing safety risks, a protective beam 3 is provided on the back of the top plate 1. The protective beam 3 limits the range of motion of the synchronizing rod 221, ensuring that the synchronizing rod 221 is within the movement interval between the protective beam 3 and the top plate 1, thereby ensuring that the gap between the second leg 22 and the top plate 1 is not easy to pinch hands, thus improving the safety during use.

[0025] The protective beam 3 includes a limiting rod 31 and two mounting pieces 32. The two mounting pieces 32 are located at both ends of the limiting rod 31 and are fixed to the back of the top plate 1. There is a moving gap between the limiting rod 31 and the top plate 1, and the synchronizing rod 221 can slide along the limiting rod 31. The mounting pieces 32 are used to fix the protective beam 3 to the back of the top plate 1. Since there needs to be a gap between the limiting rod 31 and the top plate 1, and this gap needs to accommodate the sliding of the synchronizing rod 221, a single mounting piece 32 cannot meet the requirements. Therefore, two mounting pieces 32 are provided to complete the fixation of the limiting rod 31 to the top plate 1, thereby improving the structural stability of the protective beam 3.

[0026] The folding bracket also includes a latching member 4, which passes through the moving interval and is located on the back of the top plate 1. The hinge points of the latching member 4 and the first support leg 21 on the top plate 1 are respectively located on both sides of the top plate 1. The hinge point of the first support leg 21 on the top plate 1 is located at the first end of the back of the top plate 1, and the latching member 4 is located at the second end of the back of the top plate 1. It can fix the second support leg 22 by preventing the synchronous rod 221 from moving, thereby fixing the folding bracket and improving the stability of the folding bracket when unfolded.

[0027] The snap-fit ​​component 4 includes a connecting portion 41 and a bending portion 42. The connecting portion 41 is fixedly connected to the top plate 1. One end of the bending portion 42 is fixed to the connecting portion 41, and the other end extends and bends away from the top plate 1. The bending portion 42 and the connecting portion 41 form a fixing groove 43. The fixing groove 43 is used to accommodate the scissor support assembly 2 and snaps into the scissor support assembly 2 when the folding bracket is unfolded. The synchronizing rod 221 is snapped and fixed into the snap-fit ​​component 4 when the folding bracket is unfolded. The snap-fit ​​component 4 is used to snap into the synchronizing rod 221 when the folding bracket is unfolded. The connecting portion 41 of the snap-fit ​​component 4 is fixedly connected to the top plate 1. The bending portion 42 is away from the top plate 1 and forms a fixing groove 43 with the connecting portion 41. When the folding bracket is unfolded, the synchronizing rod 221 moves into the fixing groove 43 and abuts against the inner wall of the fixing groove 43. The fixing groove 43 can prevent the synchronizing rod 221 from sliding out of the moving interval, thus improving the stability of the folding bracket.

[0028] The second support leg 22 also includes a fixing member 223, and the synchronizing rod 221 is fixed to the top of the support rod 222. The first support leg 21 has a fixing hole 211, and the support rod 222 has a hinge hole 2221. The fixing member 223 can pass through the hinge hole 2221 and be fixed in the fixing hole 211. The second support leg 22 can rotate relative to the first support leg 21 around the fixing member 223. The first support leg 21 and the second support leg 22 are hinged together, so that when the folding bracket is stored, the angle formed between the first support leg 21 and the second support leg 22 becomes 0°, that is, the first support leg 21 and the second support leg 22 rotate and overlap, which improves the storage capacity of the folding bracket. The maximum distance between the two support rods 222 of the second support leg 22 is less than the maximum distance between the two legs of the first support leg 21. When folded and stored, the second support leg 22 rotates into the interior of the first support leg 21 and is covered by the first support leg 21, which improves storage capacity and aesthetics.

[0029] When the folding bracket is folded up, the synchronizing rod 221 is close to the first end of the top plate 1; when the folding bracket is unfolded, the synchronizing rod 221 is close to the second end of the top plate 1. The synchronizing rod 221 is located in the fixing groove 43 and is engaged and fixed with the bending part 42.

[0030] The bending portion 42 includes a snap-fit ​​unit and a connecting unit. One end of the connecting unit is fixedly connected to the connecting portion 41, and the other end of the connecting unit is fixed to the snap-fit ​​unit. The snap-fit ​​unit is parallel to the top plate 1 and extends towards the top plate 1 at the end away from the connecting unit to form a blocking unit. The minimum distance between the blocking unit and the top plate 1 is less than the minimum distance between the snap-fit ​​unit and the top plate 1. When the folding bracket is unfolded, the synchronizing rod 221 is in close contact with the connecting unit, and the blocking unit is used to prevent the synchronizing rod 221 from leaving the fixing groove 43.

[0031] The top plate 1 is provided with a handle 11 at its first end. The handle 11 is used to pull the folding bracket, which can reduce the difficulty of use and transportation.

[0032] The first support leg 21 also includes a movable wheel 212, which is disposed at the second end of the first support leg 21, and the edge of the movable wheel 212 extends beyond the first support leg 21. The movable wheel 212 can reduce the difficulty of movement when the folding bracket is folded up, making it convenient for transportation.

[0033] When the folding bracket is unfolded, the handle 11 is at the same height from the ground as the top plate 1; when the folding bracket is folded up, the second end of the handle 11 relative to the top plate 1 is away from the moving wheel 212. By setting the position of the handle 11, the handle 11 is separated from the bottom of the bracket when the folding bracket is unfolded, keeping the handle 11 away from the bottom of the bracket. This prevents wear and tear on the handle 11 due to prolonged contact with dirt or other environmental factors during use, improving the safety and cleanliness of the handle 11, and eliminating the need to clean the handle 11 every time it is folded up.

[0034] During use, since the fixed rotation point of the top plate 1 and the scissor support assembly 2 is only at the top of the first leg 21, and the fixed rotation point is located at the first end of the top plate 1, the top plate 1 can be opened from the front and back. When the user accidentally opens the top plate 1 from the second end opposite to the first end, the protective beam 3 can prevent the top plate 1 from opening from the second end of the top plate 1 away from the scissor support assembly 2, preventing the formation of a gap between the top plate 1 and the second leg 22, and thus preventing the user's hand from entering the gap and being pinched, thereby improving the safety of the folding bracket during use.

[0035] The above are merely specific embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Those skilled in the art should understand that this utility model includes, but is not limited to, the contents described in the accompanying drawings and the specific embodiments above. Any modifications that do not depart from the functional and structural principles of this utility model will be included within the scope of the claims.
