Description

Technical Field

[0001] This utility model relates to the field of bags and luggage, and more specifically, to a bag and luggage frame. Background Technology

[0002] As living standards improve, more and more families are keeping pets such as cats and dogs, and owners are willing to spend more time interacting with their pets. When taking pets out for trips, pet carriers are used for convenience.

[0003] Traditional pet carrier frames are quite large and cannot be folded, which means they take up a lot of space when carried. Utility Model Content

[0004] To address the technical problem that traditional pet carrier frames are bulky and non-foldable, thus requiring a lot of space for carrying, one objective of this utility model is to provide a carrier frame.

[0005] To achieve the above objectives, an embodiment of this utility model provides a bag frame, characterized in that it includes two support frames arranged opposite to each other; a first connecting component, with both ends connected to one end of each of the two support frames; and a second connecting component, with both ends connected to the other end of each of the two support frames.

[0006] By detachably connecting the first connecting component to the two support frames and rotatably connecting the second connecting component to the two support frames, when the bag frame needs to be folded for storage, the upper ends of the two support frames can be separated by sliding the first connecting component to the right. Then, by folding the second connecting component, the two support frames can be folded for storage, further reducing the storage space of the bag frame.

[0007] In addition, the bag frame in the above embodiments provided by this utility model may also have the following additional technical features:

[0008] In the above technical solution, the support frame includes a first U-shaped rod, which includes a first open end and a first closed end; a second U-shaped rod, which includes a second open end and a second closed end, the second open end being rotatably connected to the first closed end; and a connecting rod, one end of which is rotatably connected to the second closed end.

[0009] By rotatably connecting the second open end to the first closed end, and rotatably connecting one end of the connecting rod to the second closed end, it is easier for the operator to rotate the connecting rod, the first U-shaped rod, and the second U-shaped rod, thus reducing the difficulty of operation.

[0010] In the above technical solution, the first connecting component includes a first connector, which is slidably connected to the proximal ends of two oppositely arranged connecting rods; the proximal ends of the two oppositely arranged connecting rods are respectively provided with a connecting groove and a protrusion; a cavity is formed inside the connecting rod; a spring is provided inside one of the oppositely arranged cavities; a slide rail is formed on both sides of the connecting rod, and the slide rail communicates with the cavity; a slide rod is slidably connected inside the slide rail, and the slide rod is fixedly connected to the end of the spring away from the second U-shaped rod, and the slide rod passes through the first connector.

[0011] The first connecting member is slidably connected to the near ends of two oppositely positioned connecting members. The installation and removal of the two oppositely positioned connecting rods can be completed by sliding the first connecting member. The operation is simple. The cooperation of the connecting groove and the protrusion ensures that the two oppositely positioned connecting rods can play a preliminary limiting role before sliding the first connecting member, which facilitates the subsequent sliding of the first connecting member. Through the cooperation of the spring, the slide rail and the slide rod, it can be ensured that the first connecting member is always sleeved on the near ends of the two oppositely positioned connecting rods during use, so as to prevent the first connecting member from slipping off and causing the entire device to be unstable.

[0012] In the above technical solution, the second connecting component includes a groove formed at the first open end; a first opening formed on the side of the first U-shaped rod away from the second U-shaped rod, the first opening being connected to the groove; a through hole formed on both sides of the first open end, the through hole communicating with the groove; a second connecting member, both ends of which extend into the two oppositely arranged grooves; and a rivet passing through the through hole and the second connecting member, the rivet being rotatably connected to the through hole and fixedly connected to the second connecting member.

[0013] By inserting both ends of the second connector into two opposing grooves, and opening a first opening connected to the groove on the side of the first U-shaped rod away from the second U-shaped rod, when the bag frame needs to be folded, the two first U-shaped rods can be rotated downwards, and then the connecting rod, the first U-shaped rod and the second U-shaped rod can be folded in parallel, reducing the storage space of the bag frame. The fact that the first opening connected to the groove is only opened on the side of the first U-shaped rod away from the second U-shaped rod ensures that the first U-shaped rod will not be obstructed when rotating downwards.

[0014] In the above technical solution, the second connecting member includes a first connecting plate and a second connecting plate. The second connecting plate is fixedly connected to both sides of the first connecting plate, and the two second connecting plates extend into the two oppositely arranged grooves.

[0015] By aligning the two surfaces of the first connecting plate with the two first open ends, friction between the two opposing first open ends can be avoided when the bag frame is folded, thus reducing damage to the first U-shaped rod.

[0016] In the above technical solution, a first opening connected to a groove is provided on the side of the first U-shaped rod away from the second U-shaped rod, and a limit member is slidably connected to both ends of the first U-shaped rod.

[0017] By sliding a limiting component between the two ends of one of the U-shaped rods, when the bag frame is in use, the limiting component is fitted outside the two oppositely arranged first open ends, so that the first open ends and the second connecting component remain horizontal. The limiting component can prevent the first U-shaped rod from rotating, and the bag frame can be used normally.

[0018] In the above technical solution, the limiting member has a second opening, and an elastic member is fixedly connected inside the second opening. The elastic member is interference-fitted with the first U-shaped rod.

[0019] By fixing an elastic element inside the second opening, and by interfering with the first U-shaped rod, the loosening of the limiting element can be prevented, thus ensuring that the bag frame will not rotate during use.

[0020] In the above technical solution, the length of the rivet is greater than the inner diameter of the groove.

[0021] By making the length of the rivet greater than the inner diameter of the groove, the rivet can limit the second connector and prevent it from falling off the first U-shaped rod.

[0034] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0035] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0036] The following reference Figures 1 to 8 Description of a bag frame according to some embodiments of the present invention.

[0037] like Figure 1 , Figure 2 , Figure 3 , Figure 7 As shown, an embodiment of this utility model provides a bag frame, including two support frames, a first connecting component, and a second connecting component.

[0038] Specifically, the two support frames are arranged opposite to each other; a first connecting component is connected to one end of each of the two support frames at both ends; and a second connecting component is connected to the other end of each of the two support frames at both ends.

[0039] The above-described embodiment of this utility model provides a bag frame. When the bag frame is in use, the support frame includes four free ends forming a rectangle. Therefore, two support frames are arranged opposite each other, and the four free ends on the two support frames are arranged opposite each other in pairs. The two upper opposite free ends are connected together by a first connecting component, and the two lower opposite free ends are connected together by a second connecting component. When the bag frame needs to be folded, the first connecting component is slid to the right, causing the first connecting component to disengage from the left free end, thereby causing the two upper opposite free ends to disengage. Then, the lower corresponding free ends are rotated downwards, thereby causing the two support frames to fold together, reducing storage space.

[0040] like Figure 1 , Figure 2 and Figure 7 As shown, in one embodiment of the present invention, the support frame includes a first U-shaped rod 1, which includes a first open end 2 and a first closed end 3; a second U-shaped rod 4, which includes a second open end 5 and a second closed end 6, the second open end 5 being rotatably connected to the first closed end 3; and a connecting rod 7, one end of which is rotatably connected to the second closed end 6.

[0041] Two first U-shaped rods 1 are horizontally arranged opposite each other, thereby making two first open ends 2 opposite each other. Each first open end 2 includes two free ends, and the two free ends arranged opposite each other are connected by a second connecting assembly. The second U-shaped rod 4 is vertically arranged, and the second open end 5 also includes two free ends. The two free ends of the second open end 5 are respectively rotatably connected to the two ends of the first closed end 3. The two ends of the second closed end 6 are respectively rotatably connected to connecting rods 7. Since there are two second U-shaped rods 4, the connecting rods 7 rotatably connected to the two different second U-shaped rods 4 are arranged opposite each other. The two connecting rods 7 arranged opposite each other are connected by a first connecting assembly. By rotatably connecting the two free ends of the second open end 5 to the two ends of the first closed end 3, and rotatably connecting one end of the two connecting rods 7 to the two ends of the second closed end 6, it is convenient for the operator to rotate the connecting rods 7, the first U-shaped rods 1 and the second U-shaped rods 4, reducing the difficulty of operation.

[0042] like Figure 1 , Figure 2 , Figure 7 and Figure 8As shown, in one embodiment of this utility model, the first connecting component includes a first connecting member 8, which is slidably connected to the near ends of two oppositely arranged connecting rods 7; the near ends of the two oppositely arranged connecting rods 7 are respectively provided with connecting grooves 19 and protrusions 20; a cavity 21 is opened inside the connecting rod 7; a spring 22 is disposed inside one of the oppositely arranged cavities 21; a slide rail 23 is opened on both sides of the connecting rod 7, and the slide rail 23 communicates with the cavity 21; a slide rod 24 is slidably connected inside the slide rail 23, and the slide rod 24 is fixedly connected to the end of the spring 22 away from the second U-shaped rod 4, and the slide rod 24 passes through the first connecting member 8.

[0043] It should be noted that during the use of the bag frame, the first connector 8 is slidably connected to the near ends of the two oppositely arranged connectors 7. A connecting groove 19 is provided at the end of the left connector 7 away from the left second U-shaped rod 4, and a protrusion 20 is fixedly connected at the end of the right connector 7 away from the right second U-shaped rod 4. The protrusion 20 extends into the connecting groove 19. A cavity 21 is opened inside the two oppositely arranged connectors 7. A spring 22 is located inside the cavity 21 of the right connector 7. A slide rail 23 is opened on both sides of the right connector 7 and communicates with the right cavity 21. A slide rod 24 is slidably connected inside the slide rail 23. The slide rod 24 is fixedly connected to the end of the spring 22 away from the right second U-shaped rod 4 and passes through the first connector 8.

[0044] When it is necessary to disassemble the two opposing connecting rods 7, slide the first connecting piece 8 to the right. The first connecting piece 8 drives the slide rod 24 to slide to the right along the slide rail 23. Then the slide rod 24 drives the spring 22 to slide to the right away from the end of the second U-shaped rod 4 on the right side. The spring 22 contracts until the first connecting piece 8 is completely separated from the connecting rod 7 on the left side. Then the two opposing connecting rods 7 are no longer limited by the first connecting piece 8, and the opposing connecting rods hang down.

[0045] When installing two opposing connecting rods 7, first slide the first connecting piece 8 towards the first U-shaped rod on the right. Then rotate both connecting rods 7 upwards until the protrusion 20 can be inserted into the groove. Since the outer diameter of the end of the protrusion 20 near the left connecting rod is smaller than the inner diameter of the connecting groove 19, the protrusion 20 can support the connecting groove 19 after being inserted into it. Then, simply rotate one connecting rod 7 upwards, and the other connecting rod 7 will rotate upwards together until the two connecting rods 7 are horizontal. Then release the first connecting piece 8. During the process of the spring 22 restoring its deformation, the first connecting piece 8 can be driven to fit onto the near ends of the two opposing connecting rods 7, thus completing the installation of the two opposing connecting rods 7.

[0046] The above installation process only requires rotating the connecting rod 7 and sliding the first connecting piece 8 to complete the assembly of the connecting rod 7, making the installation process simple.

[0047] like Figure 1 , Figure 4 and Figure 5 As shown, in one embodiment of this utility model, the second connecting component includes a groove 9 formed at the first open end 2; a first opening 10 formed on the side of the first U-shaped rod 1 away from the second U-shaped rod 4, the first opening 10 being connected to the groove 9; a through hole 11 formed on both sides of the first open end 2, the through hole 11 communicating with the groove 9; a second connecting member 12, both ends of which extend into the two oppositely arranged grooves 9; and a rivet 15 passing through the through hole 11 and the second connecting member 12, the rivet 15 being rotatably connected to the through hole 11 and fixedly connected to the second connecting member 12. The length of the rivet 15 is greater than the inner diameter of the groove 9.

[0048] When folding the bag frame, after the first connector 8 is disassembled, pull down the two first closed ends. Since the first open end 2 has a groove 9, the two ends of the second connector 12 extend into the two oppositely arranged grooves 9 respectively. The first U-shaped rod 1 has a first opening 10 connected to the groove 9 on the side away from the second U-shaped rod 4. Therefore, the first U-shaped rod 1 can rotate downward without being blocked by the second connector 12 until the two first U-shaped rods 1 are aligned together. Since the front and rear sides of the first open end 2 have through holes 11 connected to the groove 9, the rivet 15 passes through the through hole 11 and the second connector 12. The rivet 15 is then fixedly connected inside the second connector 12. The two ends of the rivet 15 extend out of the second connector 12 respectively. By making the length of the rivet 15 greater than the inner diameter of the groove 9, the rivet 15 can limit the second connector 12 and prevent the two ends of the second connector 12 from sliding out of the groove 9.

[0049] like Figure 5 As shown, in one embodiment of the present invention, the second connecting member 12 includes a first connecting plate 13 and a second connecting plate 14. The second connecting plate 14 is fixedly connected to both sides of the first connecting plate 13, and the two second connecting plates 14 extend into the two oppositely arranged grooves 9 respectively.

[0050] By aligning the two surfaces of the first connecting plate 13 with the two first open ends 2, friction between the two opposing first open ends 2 can be avoided when the bag frame is folded, thus reducing damage to the first U-shaped rod 1. The second connecting plate 14 is fixedly connected to both sides of the first connecting plate 13. The two second connecting plates 14 extend into the two opposing grooves 9, and the surfaces of the second connecting plates 14 are perpendicular to the rivets 15, thereby facilitating the passage of the rivets 15 through the interior of the second connecting plates 14.

[0051] like Figure 2 and Figure 3 As shown, in one embodiment of the present invention, a first opening 10 connected to a groove 9 is provided on the side of the first U-shaped rod 1 away from the second U-shaped rod 4, and a limiting member 16 is slidably connected to both ends of the first U-shaped rod.

[0052] By slidingly connecting the two ends of the first U-shaped rod 1 on the left side with limiting members 16, which are made of rigid materials such as metal and plastic, the limiting members 16 can provide good support when the bag frame is compressed, preventing damage to the limiting members 16. When the bag frame is in use, the limiting members 16 are fitted over the two oppositely arranged first open ends 2, keeping the two first U-shaped rods 1 horizontal. The limiting members 16 prevent the first U-shaped rods 1 from rotating, allowing the bag frame to function normally. When the bag frame needs to be folded, the limiting members 16 are slid to the left, causing them to disengage from the two oppositely arranged first open ends 2. The first U-shaped rods 1 are no longer limited by the limiting members 16 and can rotate downwards normally.

[0053] like Figure 2 , Figure 3 and Figure 6 As shown, in one embodiment of the present invention, the limiting member 16 has a second opening 17, and an elastic member 18 is fixedly connected inside the second opening 17. The elastic member 18 is interference-fitted with the first U-shaped rod 1.

[0054] A second opening 17 is provided at the left end of the side wall of the limiting member 16, and an elastic member 18 is fixedly connected inside the second opening 17. The elastic member 18 can be made of rubber. The elastic member 18 is interference-fitted with the first U-shaped rod 1, which can prevent the limiting member 16 from loosening and further ensure that the bag frame will not rotate during use.

[0055] It should be noted that if the elastic element 18 is located at the left end of the limiting element 16, then the limiting element 16 is slidably connected to the first U-shaped rod 1 on the left side. If the elastic element 18 is located at the right end of the limiting element 16, then the limiting element 16 is slidably connected to the first U-shaped rod 1 on the right side. This can reduce the sliding distance and sliding difficulty of the limiting element 16.

[0056] This utility model has the following advantages:

[0057] 1. The first connecting component is slidably connected at the upper connection point of the left support frame and the right support frame. Simply slide the first connecting component to the right to detach the upper ends of the two support frames from each other, making the operation simple.

[0058] 2. The second connecting component allows the two support frames to be folded together, reducing storage space. After the upper ends of the two support frames are detached, the entire support frame can be folded together simply by pulling down the support frame, making the operation process easy.
