Description

Technical Field

[0001] This utility model belongs to the field of power fittings technology, and in particular relates to a turnbuckle. Background Technology

[0002] Turnbulls, as electrical fittings used for tensioning power cables, are widely used in cable laying construction. A turnbull typically consists of a bolt body and tie rods connecting both ends of the body. Existing turnbull bodies usually have a slotted hole in the middle. When installing or removing the turnbull nut, a rod-like tool, such as a rebar or screwdriver, needs to be inserted into the slotted hole, and then the tool must be moved around the tie rod to remove or install the turnbull nut. This process can only be done manually, making it very time-consuming and resulting in low efficiency in removing and installing turnbull nuts. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a turnbuckle that can be connected to a ratchet tool, which helps to improve assembly and disassembly efficiency.

[0004] In order to achieve the purpose of this utility model, the following solution is proposed:

[0005] A turnbuckle includes: a body and two tie rods. The outer ends of the tie rods are provided with connecting structures, and the inner ends of the tie rods are respectively connected to both ends of the body along the length direction by a screw structure. The middle section of the body has a connecting post, which is coaxial with the tie rods at both ends of the body. The cross section of the connecting post is an even-numbered regular polygon. A strip hole is provided between the connecting post and both ends of the body, and the inner ends of the tie rods are located in the strip holes at the corresponding ends.

[0006] The beneficial effects of this utility model are as follows: This solution sets a connecting post on the body of the turnbull, which can be used to connect with a ratchet wrench. The ratchet wrench can quickly rotate the body, thereby achieving the purpose of quickly assembling and disassembling the turnbull. Attached Figure Description

[0010] Figure 3 It shows along Figure 2 A cross-sectional view along the AA direction.

[0011] The markings in the diagram are: Body-1, Connecting Post-11, Strip Hole-12, Tie Rod-2, Mounting Hole-21, and Mandrel-3. Detailed Implementation

[0012] To make the objectives, technical solutions and advantages of the present utility model clearer, the implementation methods of the present utility model will be described in detail below with reference to the accompanying drawings. However, the embodiments described in the present utility model are only some embodiments of the present utility model, and not all embodiments.

[0013] like Figures 1 to 3 As shown, a turnbuckle includes: a long strip-shaped body 1 and two tie rods 2. The outer ends of the tie rods 2 are provided with connecting structures for connecting cables. The connecting structures at the outer ends of the tie rods 2 are rings or hooks. The inner ends of the tie rods 2 are connected to both ends of the body 1 along the length direction by screw structures. The middle section of the body 1 has a connecting post 11, which is coaxial with the tie rods 2 at both ends of the body 1. The cross-section of the connecting post 11 is an even-numbered regular polygon, such as a regular square, a regular hexagon, or a regular dodecagon. A strip hole 12 is provided between the connecting post 11 and both ends of the body 1, and the inner ends of the tie rods 2 are located in the corresponding strip holes 12.

[0014] Using the above mechanism, when installing or removing turnbuckles, a ratchet wrench can be connected to the connecting post 11. The ratchet wrench allows for quick rotation of the body 1, thus enabling rapid installation or removal of turnbuckles. The ratchet wrench can be a manual open-end ratchet wrench or a pneumatic open-end ratchet wrench. Furthermore, this solution uses the connecting post 11 to divide the strip hole 12 of the entire structure in the prior art into two sections, which helps to improve the structural strength of the middle section of the body 1. By placing the connecting post 11 in the middle section of the body 1, the uniformity of force at both ends can be effectively maintained when rotating the body 1.

[0015] Preferably, the connecting column 11 is integrally stamped with the body 1.

[0016] Preferred, such as Figures 1 to 3 As shown, the outer contour of the cross section of the connecting post 11 is smaller than that of the cross section of the body 1 to meet the material requirements during stamping. Furthermore, this structural design also enables the connecting post 11 to form a necked structure in the middle section of the body 1, so as to secure the ratchet wrench and prevent the ratchet wrench from sliding along the length of the body 1.

[0017] Preferred, such as Figures 1 to 3As shown, a mandrel 3 is coaxially inserted through the connecting column 11, and mounting holes 21 are coaxially opened on the inner ends of the pull rods 2. The two ends of the mandrel 3 are respectively inserted into the mounting holes 21 of the two pull rods 2. Because the pull rods 2 are connected to the body 1 through a screw structure, there will inevitably be a gap between the threaded connection between the screw and the body 1. Therefore, the existing pull rods 2 often become misaligned during installation, which affects the smoothness of tightening the turnbuckle. This solution uses the mandrel 3 to position the pull rods 2, which can effectively ensure the coaxiality between the pull rods 2 and the threaded holes of the body 1, and prevent the pull rods 2 from becoming misaligned, thereby improving the smoothness of the tightening process.

[0018] Preferred, such as Figure 1 As shown, both ends of the body 1 have coaxial hexagonal prisms, which can increase the connection points for the ratchet wrench. When the outer contour of the connecting post 11 is worn, the ratchet wrench can be connected by the hexagonal prisms at both ends to continue to achieve the purpose of quick assembly and disassembly.

[0019] The above description is merely a preferred embodiment of this utility model and does not imply its uniqueness or limitation. Those skilled in the art should understand that various changes or equivalent substitutions made to this utility model without departing from its scope are all within the protection scope of this utility model.
