Description

Technical Field

[0001] The utility model relates to the technical field of circular looms, in particular to an electric jumper for circular looms. Background Art

[0002] In the prior art, the traditional electric jumper includes an insulating frame, a conductive rod body and a tension spring, one end of the tension spring forms an annular hanging hole end, and the other end forms a hook end. Since the spring is relatively thin, the hook end is prone to breakage or deformation after long-term use, thus affecting its use. Therefore, an electric jumper has appeared on the market, which uses an abutment rod and a spring, such as the Chinese utility model patent with patent number "202022455315.9". Because the abutment rod is pressed by the elastic reset force on the side, dust is easily accumulated on the rear side of the abutment rod after long-term use, and the elastic fatigue of the spring will affect the overall conductive performance. There is also a conductive spring piece that directly replaces the tension spring, such as the Chinese utility model patent with patent number "202223502086.7". The spring piece is prone to elastic fatigue after long-term use, and further dust is easily accumulated, thereby affecting the conductive performance. Moreover, the replacement of the electric jumper usually requires a pit to appear in the threading hole to determine that the electric jumper is damaged. When it is used normally, if the conductive performance is poor, it is not easy to be discovered, so the electric jumper on the market still has relatively large defects. Summary of the invention

[0003] Purpose of the utility model: In order to overcome the defects of the prior art, the utility model provides an electric jumper for a circular loom, which prevents the hook from breaking and deforming by further setting the hook of the tension spring, and has better conductive performance and is more practical.

[0004] The utility model discloses an electric jumper for a circular loom, which comprises an elastic reset member, an insulating frame and a conductive wire rod, one end of the conductive wire rod is provided with a threading hole, and is characterized in that: the elastic reset member comprises a spring and a draw hook which are separately arranged, one end of the spring is provided with a hanging hole, the draw hook comprises a limiting end and a hooking end, the limiting end is inserted into an end of the spring away from the hanging hole, and also comprises a limiting structure for limiting the withdrawal of the limiting end.

[0005] By adopting the above technical solution, the spring and the hook are arranged separately, so that the two can be made of materials with different structural stiffness, so that the structural stiffness can be increased at the hook position alone, thereby slowing down the breakage or deformation of the hook, and further improving the stability of the structure.

[0006] The utility model is further configured as follows: the limiting structure includes a top of the limiting end being relatively bent to form an anti-slip ring.

[0007] By adopting the above technical solution, the outer diameter can be increased by bending, thereby preventing the hook from falling off.

[0008] The utility model is further configured as follows: the bottom of the spring is shrunken to form a tower-shaped limiting portion, and the ring opening at the end of the tower-shaped limiting portion is smaller than the outer diameter of the anti-slip ring.

[0009] By adopting the above technical solution, the anti-slip ring can be restricted from detaching by shrinking the mouth, thereby further increasing stability.

[0010] A further configuration of the utility model is as follows: the diameter of the draw hook is d1, the diameter of the spring is d2, and d1 is greater than d2.

[0011] By adopting the above technical solution, since d1 is greater than d2, the structural rigidity can be further increased to prevent the hook from breaking, thereby increasing the contact area and enhancing the conductive performance.

[0012] The utility model is further configured as follows: the limit end can move relative to the spring, and when the limit end moves to a specified position, the anti-slip ring can abut against the tower-shaped limit part to form a limit.

[0013] By adopting the above technical solution, when the spring elastically resets, the draw hook can slide relatively adaptively, thus avoiding a hard collision. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The following is a detailed description of the specific implementation of the utility model in conjunction with the accompanying drawings:

[0019] In the description of the present invention, it should be understood that the terms "upper", "lower", "bottom", "top", "front", "back", "inside", "outside", "left", "right", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0020] The utility model discloses an electric jumper for a circular loom, which comprises an elastic reset member 1, an insulating frame 2 and a conductive wire rod 3, one end of the conductive wire rod 3 is provided with a threading hole 31, in the implementation case of the utility model, the elastic reset member 1 comprises a spring 11 and a draw hook 12 which are arranged in a split manner (the spring 11 and the draw hook 12 are both made of conductive materials and belong to the prior art, which will not be described in detail in this article), one end of the spring 11 is provided with a hanging hole 111, the draw hook 12 comprises a limiting end 121 and a hooking end 122, the limiting end 121 is inserted into the spring 11 far away One end of the hanging hole 111 also includes a limiting structure for limiting the withdrawal of the limiting end 121. Through the separately arranged spring 11 and the hook 12, it is most preferred that the diameter of the hook 12 is d1, and the diameter of the spring 11 is d2, and d1 is greater than d2. Because d1 is greater than d2, the structural rigidity can be further increased to prevent the hook 12 from breaking, thereby increasing the contact area and enhancing the conductive performance. Of course, the two can be made of materials with different structural rigidity, so that the structural rigidity can be increased at the position of the hook 12 alone, thereby slowing down the breakage or deformation of the hook 12.

[0021] The limiting structure includes a limiting end 121 whose top is relatively bent to form an anti-drop ring 4. The outer diameter can be increased by bending, thereby preventing the hook 12 from falling off.

[0022] The bottom of the spring 11 is shrunken to form a tower-shaped limiting portion 112. The ring opening at the end of the tower-shaped limiting portion 112 is smaller than the outer diameter of the anti-slip ring 4. The shrinking method can limit the anti-slip ring 4 from detaching, further increasing stability.

[0023] The limiting end 121 can move relative to the spring 11. When the limiting end 121 moves to a specified position, the anti-slip ring 4 can abut against the tower-shaped limiting portion 112 to form a limit. When the spring 11 elastically resets, the hook 12 can slide relatively and adaptively to avoid a head-on collision.
