Description

Technical Field

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

[0002] In the fields of logistics transportation and cargo storage, the stability and secure fixing of goods are crucial, as they not only concern safety during transportation but also directly impact the efficiency of warehouse management. Tensioners, a commonly used cargo securing tool, function to stabilize goods by tightening straps or chains, preventing displacement or collapse during transport.

[0003] Chinese Patent Publication No. CN 222247842U discloses a folding tensioner, which includes a main body, a fixed shaft, and a tensioning handle. The main body and the tensioning handle are connected and assembled via the fixed shaft, and the tensioning handle can rotate around the fixed shaft. A ratchet is mounted on the fixed shaft, and the tensioning handle is provided with a first limiting groove, in which a stop plate capable of engaging the teeth of the ratchet is mounted. A second limiting groove is provided on the main body, in which a limiting piece capable of engaging the teeth of the ratchet is mounted. A connecting end post is provided on the end face of the fixed shaft, and the connecting end post is used to connect an external power tool.

[0004] However, this folding tensioner uses a ratchet drive to achieve tension, and the tensioning action can only be achieved by passing the pull strap through the slot. This makes it difficult to meet the requirements for tensioning the pull strap when the pull rope is too short, and it needs to be improved. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a folding tensioner, which has the advantages of simple structure, convenient operation and suitability for any length requirement.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A folding tensioner includes a tensioning shaft, two telescopic tubes respectively inserted into the inner sides of both ends of the tensioning shaft, and hooks connected to the telescopic tubes; at least one end of the tensioning shaft is provided with a driving member, which is used to drive the telescopic tubes to move linearly along the axial direction of the tensioning shaft, and the driving member is foldably connected to a wrench.

[0008] Preferably, the tensioning shaft includes a threaded connection section and a plug section, the inner diameter of the plug section is larger than the diameter of the telescopic tube, the telescopic tube is threadedly connected to the threaded connection section, and the plug section is provided with an oil injection hole.

[0009] Preferably, the telescopic tube has a hinged joint at one end away from the tensioning shaft, and a connecting rod is hinged to the hinged joint. The other end of the connecting rod is rotatably connected to the hook.

[0010] Preferably, the driving component includes an adjusting part and a mating part. The adjusting part is used to be detachably connected and fixed to the telescopic cannula, and the mating part is used to cooperate with the adjusting part to drive the telescopic cannula to rotate or separate and be stored.

[0011] Preferably: the adjusting part is provided with an adjusting groove, and the mating part is provided with a mating groove that matches and communicates with the adjusting groove; the mating groove is provided with a cam tooth, and the adjusting groove is provided with an adjusting tooth. The adjusting tooth is connected and fixed to the corresponding telescopic insertion pin. The long diameter end of the cam tooth is used to engage with the adjusting tooth, and the short diameter end is used to separate from the adjusting tooth. The mating groove is provided with a fixing member for connecting and fixing to the short diameter end of the cam tooth. The cam tooth is inserted and fixed with a mating handle for circumferential rotation.

[0012] Preferably, the fixing member includes a cooperating spring and a cooperating steel ball that abuts against one end of the cooperating spring, and the short diameter end of the cam tooth is provided with a steel ball groove that matches the cooperating steel ball.

[0013] Preferably, the mating part is provided with a folding protrusion, and a mating rotating body is fixedly connected inside the folding protrusion. The mating rotating body is provided with two arc-shaped grooves with an included angle of 90°, and an arc-shaped surface is formed between two adjacent arc-shaped grooves.

[0018] To make the technical solution and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0019] like Figure 1 As shown, a folding tensioner includes a tensioning shaft 1, two telescopic tubes 2 respectively inserted into the inner sides of both ends of the tensioning shaft 1, and hooks 4 connected to the telescopic tubes 2. A tension strap is used to secure the tensioning shaft 1 to the hooks 4, and a driving element 7 is provided at at least one end of the tensioning shaft 1. The driving element 7 drives the telescopic tubes 2 to move linearly along the axial direction of the tensioning shaft 1, and the driving element 7 is foldably connected to a wrench part 6. The wrench part 6 reduces the difficulty of driving the driving element 7.

[0020] It should be noted that the tensioning shaft 1 includes a threaded connection section 11 and a plug-in section 12. The inner diameter of the plug-in section 12 is larger than the diameter of the telescopic tube 2. The telescopic tube 2 is threadedly connected to the threaded connection section 11, and the plug-in section 12 is provided with an oil injection hole 121. At the same time, a hinged joint 3 is provided at the end of the telescopic tube 2 away from the tensioning shaft 1, and a connecting rod 5 is hinged to the hinged joint 3. The other end of the connecting rod 5 is rotatably connected to the hook 4. Therefore, when the telescopic tube 2 is driven to rotate, the telescopic tube 2 will rotate relative to the tensioning shaft 1 and the hinged joint 3 of the connecting rod 5, so as to prevent the pull strap, which is fixed by the hook 4, from forming a twisted shape under the rotation drive of the telescopic tube 2, thus affecting the service life of the pull strap and the difficulty of disassembly and assembly.

[0021] like Figure 1As shown in the figure, the driving component 7 includes an adjusting part 71 and a mating part 72. The adjusting part 71 is used for detachable connection and fixation with the telescopic tube 2, and the mating part 72 is used for mating connection with the adjusting part 71 to drive the telescopic tube 2 to rotate or separate and be stored. The adjusting part 71 has an adjusting groove 711, and the mating part 72 has a mating groove 721 that matches and communicates with the adjusting groove 711. Meanwhile, a cam tooth 75 is provided in the mating groove 721, and an adjusting tooth 76 is provided in the adjusting groove 711. The adjusting tooth 76 is connected and fixed to the corresponding telescopic tube 2 pin. The long-diameter end of the cam tooth 75 is used to engage with the adjusting tooth 76, and the short-diameter end is used to separate from the adjusting tooth 76. A fixing member is provided in the mating groove 721 for connecting and fixing to the short-diameter end of the cam tooth 75. The cam tooth 75 is inserted and fixed to a mating handle 8 for circumferential rotation. Therefore, by rotating the handle 8, the cam tooth 75 can be driven to rotate, so that the long diameter end of the cam tooth 75 meshes with the adjusting tooth 76 or the short diameter end matches the adjusting tooth 76, thereby separating the adjusting tooth 76 from the cam tooth 75.

[0022] It should be mentioned that the fixing component includes a mating spring 73 and a mating steel ball 74 abutting against one end of the mating spring 73. The short-diameter end of the cam tooth 75 is provided with a steel ball groove that matches the mating steel ball 74. Therefore, when the long-diameter end of the cam tooth 75 meshes with the adjusting tooth 76, the mating steel ball 74 is embedded in the steel ball groove, and forms a stable connection structure with the steel ball groove through the force applied by the mating spring 73. In this embodiment, the mating spring 73 and the mating steel ball 74 protrude from the mating portion 72 to facilitate control of the mating steel ball 74 disengaging from the steel ball groove.

[0023] like Figure 1 , Figure 2As shown, the mating part 72 is provided with a folding protrusion 722. The folding protrusion 722 is either detachably connected and fixed to the mating part 72 or integrally formed on the mating part 72. A mating rotating body 723 is fixedly connected inside the folding protrusion 722, and two arc-shaped grooves 7232 with an included angle of 90° are provided on the mating rotating body 723. The two arc-shaped grooves 7232 are located at the other end facing the tensioning shaft 1 and the outer side, respectively, and an arc-shaped surface 7231 is formed between the two arc-shaped grooves 7232. At the same time, the wrench part 6 is rotatably connected to the mating rotating body 723, and a wrench spring 61 and a wrench ball 62 are provided on the wrench part 6. The wrench spring 61 is used to apply a force toward the mating rotating body 723 to the wrench ball 62, and the wrench ball 62 is used to be fixed in the arc-shaped groove 7232 or move along the arc-shaped surface 7231. Therefore, when the wrench ball 62 is embedded in the arc-shaped groove 7232 located at the other end facing the tensioning shaft 1, the wrench part 6 is horizontal with the tensioning shaft 1, thereby achieving an effective folding and storage effect. When the wrench ball 62 is embedded in another arc-shaped groove 7232, the wrench part 6 is perpendicular to the tensioning shaft 1, thereby achieving the purpose of effectively controlling the rotation of the telescopic insertion tube 2. It should be noted that parts of the wrench spring 61 and the wrench ball 62 protrude from the wrench part 6 to facilitate control of the wrench ball 62 disengaging from the corresponding arc-shaped groove 7232.

[0024] In summary, this application provides a folding tensioner, which has the following advantages: the wrench part 6 drives the drive member 7 to move, thereby enabling the drive member 7 to drive the telescopic tube 2 to move, thus achieving an effective tensioning action when the telescopic tube 2 moves into the tensioning shaft 1, and the tensioning action is stable and continuous, and achieving an effective relaxation action when the telescopic tube 2 moves outward from the tensioning shaft 1, so that the folding tensioner has the advantages of simple structure, convenient operation and applicability to any length requirement.
