Description

Technical Field

[0001] The utility model relates to the technical field of use of plug-in lightning arresters, in particular to a pulling jig. Background Art

[0002] Currently, power supply products are being updated and iterated at a rapid pace. To meet market demand, the size and structure of power supply products are becoming increasingly refined and modular, while also placing higher demands on their performance. 1U (1U = 44.45mm) pluggable lightning arresters installed within power supply products (such as towers) can better protect the safe operation of equipment and prevent it from being struck by lightning. However, these 1U pluggable lightning arresters are limited by the available installation space, resulting in relatively small length, width, and height dimensions, and they need to be inserted quite deeply. This makes them quite difficult to remove during use and maintenance. Pulling them out by hand alone is difficult, and using pliers to pull them out can easily damage the product, affecting its appearance. Utility Model Content

[0003] In view of the deficiencies in the prior art, the present invention aims to provide a pulling fixture to facilitate the removal of a plug-in lightning arrester.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] A pulling fixture comprises a first clamping jaw, a second clamping jaw, a first connector, a second connector, a first handle and a second handle; the first clamping jaw and the second clamping jaw are connected to the first connector and the second connector, respectively, and the first connector and the second connector are connected to the first handle and the second handle, respectively; the first connector and the second connector are connected in an X-shape, and the intersection of the first connector and the second connector is connected by a rotating shaft, so that the first connector and the second connector can rotate relative to each other.

[0006] As a preferred solution, one end of the connector 1 and the connector 2 are detachably connected to the claw 1 and the claw 2 respectively through fixing screws, and the other end of the connector 1 and the connector 2 are detachably connected to the handle 1 and the handle 2 respectively through fixing screws.

[0007] As a preferred solution, the front ends of the first and second clamping claws both have inwardly bent portions.

[0008] As a further preferred solution, an obtuse angle is formed between the bent portion and the inner side surface of the first or second clamping claw.

[0009] As a preferred solution, the handle 1 and the handle 2 are both ring-shaped.

[0010] As a preferred solution, the first clamping claw, the second clamping claw, the first connecting piece, the second connecting piece, the first handle and the second handle are all made of aluminum.

[0011] The beneficial effect of the utility model is that the pulling fixture of the utility model can clamp the handle of the plug-in lightning arrester through the claws, and clamp and pull out the plug-in lightning arrester through the handle, thereby realizing convenient and easy pulling of the plug-in lightning arrester. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] Figure 1 It is a structural schematic diagram of the drawing jig in an embodiment of the present utility model. DETAILED DESCRIPTION

[0013] The present invention will be further described below in conjunction with the accompanying drawings. It should be noted that this embodiment is based on the technical solution and provides a detailed implementation method and specific operation process, but the protection scope of the present invention is not limited to this embodiment.

[0014] This embodiment provides a pulling fixture, which is mainly used for pulling out the lightning arrester. Figure 1 As shown, it includes claw 1, claw 2, connecting piece 1, connecting piece 2, handle 1 5 and handle 2 6; the claw 1 and claw 2 are connected to connecting piece 1 3 and connecting piece 2 4 respectively, and connecting piece 1 3 and connecting piece 2 4 are connected to handle 1 5 and handle 2 6 respectively; the connecting piece 1 3 and connecting piece 2 4 are connected in an X shape, and the intersection of connecting piece 1 3 and connecting piece 2 4 is connected by a rotating shaft 7, so that connecting piece 1 3 and connecting piece 2 4 can rotate relative to each other.

[0015] In this embodiment, one end of the connecting member 1 3 and the connecting member 2 4 are detachably connected to the claw 1 1 and the claw 2 2 respectively through the fixing screw 8, and the other end of the connecting member 1 3 and the connecting member 2 4 are detachably connected to the handle 1 5 and the handle 2 6 respectively through the fixing screw 8.

[0016] In this embodiment, the front ends of both claw 1 and claw 2 have an inwardly bent portion 9. More specifically, an obtuse angle is formed between the bent portion 9 and the inner side surface of the corresponding claw 1 or claw 2. By providing these obtuse-angled bends at the front ends of claws 1 and 2, claws 1 and 2 can better fit the structure of the pluggable lightning arrester. They can more securely grip the handles on both sides of the pluggable lightning arrester, preventing them from slipping when pulled outward.

[0017] In this embodiment, the handle 1 5 and the handle 2 6 are both ring-shaped. The ring-shaped handle is more convenient to grasp and apply force.

[0018] In this embodiment, the first and second clamping claws, the first and second connectors, the first and second connectors, the first and second handles are all made of aluminum. Aluminum is lightweight and rust-resistant, making it more suitable for pulling and removing lightning arresters, and is less likely to scratch the lightning arrester.

[0019] When in use, hold handle 1 and handle 2 with your hands, align claw 1 and claw 2 with the handle positions on both sides of the plug-in lightning arrester to be pulled out, and then drive handle 1 and handle 2 to move toward each other by hand, thereby driving claw 1 and claw 2 to move toward each other through connector 1 and connector 2, thereby locking the handle position. At this time, you can pull the plug-in lightning arrester outward to pull it out.

[0020] Those skilled in the art can make various corresponding changes and modifications based on the above technical solutions and concepts, and all of these changes and modifications should be included in the scope of protection of the claims of this utility model.
