Technical Field

[0001] The utility model relates to the technical field of mosquito net support components, in particular to a folding connecting rod component. Background Art

[0002] The connecting rod assembly is a long rod structure composed of multiple short rods. It is often used to take into account the working environment within a length range or to achieve convenient storage. It is widely used on mosquito net support frames. The mosquito net support frame is often composed of multiple connecting rods and connectors to achieve convenient storage. However, the connection method of each connecting rod in the connecting rod assembly used on the current mosquito net support frame is relatively complicated, which greatly increases the cost.

[0003] In order to solve the problems existing in the prior art, technicians in this field have made many efforts. For example, Chinese patent application CN220607922U proposed a connecting skeleton, and further proposed a connecting rod connecting part, which realizes the folding function of the connecting rod by fitting two parts together; although the structural complexity is reduced to a certain extent, the implementation method is slightly complicated. Utility Model Content

[0004] In order to solve the above problems, the utility model provides a folding connecting rod assembly, which realizes the fixing and folding functions by means of a first connecting rod and a second connecting rod being connected by a socket and a built-in elastic member, and has a simple structure and is easy to implement.

[0005] To achieve the above-mentioned purpose, the technical solution adopted by the utility model is a folding connecting rod assembly, including a first connecting rod, a second connecting rod and an elastic member; the first connecting rod and the second connecting rod are both hollow; the first connecting rod and the second connecting rod are socket-connected; one side of the elastic member is placed inside the first connecting rod and fixedly connected to the first connecting rod, and the other side is placed inside the second connecting rod and fixedly connected to the second connecting rod.

[0006] Furthermore, hanging parts are provided at both ends of the elastic member; hanging points are provided on the inner walls of the first connecting rod and the second connecting rod; and the elastic member is fixedly connected with the first connecting rod and the second connecting rod by cooperating with the hanging parts and the hanging points.

[0007] Furthermore, the first connecting rod is provided with a first connecting portion; the second connecting rod is provided with a second connecting portion; the second connecting portion is inserted into the first connecting portion; and is slidably connected to the first connecting portion.

[0008] Furthermore, a limiting ring is provided on the inner wall of the first connecting rod and the outer wall of the second connecting rod, so as to block the first connecting part and the second connecting part.

[0009] Furthermore, the utility model proposes a folding mosquito net support frame, which is composed of a folding connecting rod assembly, including multiple three-way connectors, multiple vertical rods and multiple groups of connecting rod assemblies; the three-way connectors are respectively connected to the ports of the vertical rods and the connecting rod assemblies; together forming a polygonal structure.

[0010] Furthermore, the three-way connector includes a base, a transverse sleeve, a longitudinal sleeve and a vertical sleeve; the transverse sleeve is hinged to the base; the longitudinal sleeve is hinged to the base; and the vertical sleeve is fixedly connected to the base.

[0011] Furthermore, the transverse side and the longitudinal side of the base are in an arch shape, so as to limit the rotation of the transverse sleeve and the longitudinal sleeve.

[0012] Furthermore, a rotating shaft is provided on both the horizontal side and the vertical side of the base; the horizontal sleeve and the vertical sleeve are hinged to the base via the rotating shaft.

[0013] The technical solution described in the utility model has the following beneficial effects:

[0014] 1. The utility model respectively arranges a first connecting portion and a second connecting portion on the first connecting rod and the second connecting rod, realizes the connection between the first connecting portion and the second connecting portion through a socket connection, and arranges an elastic member in its internal space, so that the two ends of the elastic member are respectively fixedly connected to the first connecting rod and the second connecting rod, and utilizes the elastic force of the elastic member to maintain the connection state of the two connecting rods to ensure normal work. At the same time, the elastic member is utilized to realize the convenient disassembly of the first connecting rod and the second connecting rod, realizes the effect of rapid folding, simplifies the structure and implementation method, and ensures the convenience of foldability.

[0015] 2. The utility model provides limiting rings on the inner wall of the first connecting rod and the outer wall of the second connecting rod. The limiting ring on the first connecting rod is used to form a block for the second connecting part, and the limiting ring on the outer wall of the second connecting rod is used to form a block for the first connecting part. The first connecting rod and the second connecting rod are fixed by the tension of the tension spring and the blocking formed by the limiting ring on the first connecting rod, which simplifies the structure and strengthens the structural strength, thereby ensuring the stability of the connecting rod assembly in the working state.

[0016] 3. The utility model designs the horizontal and vertical sides of the three-way connector into an arch shape and utilizes the plasticity of the material itself.

DETAILED DESCRIPTION

[0025] The technical solution of the utility model is further explained below in conjunction with the accompanying drawings, but it is not limited to this. Any modification or equivalent replacement of the technical solution of the utility model without departing from the spirit and scope of the technical solution of the utility model should be included in the protection scope of the utility model.

[0026] like Figure 1As shown, this embodiment proposes a folding connecting rod assembly, including a first connecting rod 1, a second connecting rod 2 and an elastic member 3; the first connecting member and the second connecting member are hollow tube-shaped, and the elastic member 3 is a tension spring; the first connecting rod 1 is provided with a first connecting portion 11 at the right end; the second connecting rod 2 is provided with a second connecting portion 21 at the left end; the inner diameter of the first connecting portion 11 is slightly larger than the outer diameter of the second connecting portion 21, so that the second connecting portion 21 can be just inserted into the first connecting portion 11, thereby realizing the socket connection between the first connecting rod 1 and the second connecting rod 2. Hanging portions 31, i.e. hooks, are provided at both ends of the elastic member 3; hanging points 13 are fixed on the inner walls of the first connecting rod 1 and the second connecting rod 2, and the hook at one end of the tension spring is hung on the hanging point 13 inside the first connecting rod 1, and the hook at the other end is hung on the hanging point 13 inside the second connecting rod 2, so that half of the tension spring is located in the first connecting rod 1, and the other half is located in the second connecting rod 2. When the second connecting rod 2 is inserted into the first connecting rod 1 to form the working state of the connecting rod assembly, the tension spring is in a slightly stretched state, thereby forming a pulling force on both the first connecting rod 1 and the second connecting rod 2, thereby preventing the second connecting rod 2 from slipping out; when the connecting rod assembly needs to be folded, the first connecting rod 1 is pulled to the left and the second connecting rod 2 is pulled to the right respectively, so that the tension spring is in a larger stretched state, thereby pulling the second connecting rod 2 out of the first connecting rod 1, and the folding action can be performed to realize the quick folding and storage function of the connecting rod assembly.

[0027] Preferably, a limiting ring 12 is provided on the inner wall of the first connecting rod 1 and the outer wall of the second connecting rod 2. The limiting ring 12 on the first connecting rod 1 is used to block the second connecting part 21, and the limiting ring 12 on the outer wall of the second connecting rod 2 is used to block the first connecting part 11. The first connecting rod 1 and the second connecting rod 2 are fixed by the tension of the tension spring and the blocking formed by the limiting ring 12, thereby simplifying the structure and enhancing the structural strength, thereby ensuring the stability of the connecting rod assembly in the working state.

[0028] Preferably, the limiting ring 12 has a thickness, and a surface of the limiting ring 12 opposite to the first connecting part 11 or the second connecting part 21 is set to be concave, and a gap formed at the concave part matches the thickness of the first connecting part 11 or the second connecting part 21, thereby ensuring the structural tightness of the entire connecting rod assembly.

[0029] Preferably, the present embodiment further proposes a folding mosquito net support frame, comprising eight three-way connectors 4, four vertical rods 5 and eight groups of folding connecting rod assemblies, constituting a polygonal folding mosquito net support frame; wherein the three-way connector 4 comprises a base 47, a transverse sleeve 41, a longitudinal sleeve 42 and a vertical sleeve 43; the base 47 is made of plastic material, is L-shaped, and comprises a longitudinal side 45 and a transverse side 44, and the longitudinal side 45 and the transverse side 44 are both semi-closed circular tubes to form an arch-shaped structure; a rotating shaft 46 is provided on the longitudinal side 45 and the transverse side 44, and the transverse sleeve 41 and the longitudinal sleeve 42 are respectively arranged in the transverse side 44 and the longitudinal side 45, and are hinged to the base 47 through the rotating shaft 46; the vertical sleeve 43 is fixed on the base 47 to form a three-way structure. When in use, the transverse sleeve 41 is placed in the arch structure of the transverse side 44 of the base 47, and the longitudinal sleeve 42 is placed in the arch structure of the longitudinal side 45 of the base 47. The arch structure can be used to limit the rotation of the transverse sleeve 41 and the longitudinal sleeve 42 to maintain a normal working state. When folding is required, external force is applied to the transverse sleeve 41 and the longitudinal sleeve 42, and the elastic force of the plastic material itself can be used to open the two sides of the arch structure, thereby releasing the restriction of the arch structure on the transverse sleeve 41 and the longitudinal sleeve 42, so that the transverse sleeve 41 and the longitudinal sleeve 42 can be rotated to achieve the folding action.

[0030] Specifically, when forming the folding mosquito net support frame, eight three-way connecting assemblies are respectively placed at eight corner positions of the polygonal structure, the two ends of the vertical rod 5 are respectively connected to the vertical sleeve 43 of the three-way connecting piece 4, the two ends of the folding connecting rod assembly arranged in the length direction are respectively connected to the transverse sleeve 41 of the three-way connecting piece 4, and the folding connecting rod assembly arranged in the width direction is respectively connected to the longitudinal sleeve 42 of the three-way connecting piece 4, so that the two ends of each group of connecting rod assemblies are connected to the three-way connecting piece 4, and the two ends of each vertical rod 5 are connected to the three-way connecting piece 4, so that a closed structure can be formed. When folding is required, the folding of the entire folding mosquito net support frame can be achieved by folding the transverse sleeve 41, the longitudinal sleeve 42 and the folding connecting rod assembly, and closing the vertical rod 5 to the middle.
