Description

Technical Field

[0001] The utility model relates to the technical field of protective covers, in particular to a protective cover fixing tool. Background Art

[0002] When using plasma automatic welding or manual tungsten inert gas welding to weld stainless steel, titanium, zirconium and other non-ferrous metals, the back side needs to be protected by a drag hood throughout the process. At this time, workers are required to use the drag hood to follow the weld pool all the time to keep the weld in an inert gas. First, make a tool, fix the protective hood on the cylinder, and then inflate it to achieve automatic protection without manual labor.

[0003] However, the currently used protective cover fixing tool requires workers to manually take the supporting cover and follow the weld pool so that the protective cover can be stably placed on the cylinder. The protection effect is poor, and the cylinder surface is relatively smooth and hard, which is easy to loosen while being fixed, and excessive pressure may cause damage to the protective cover.

[0004] In view of this, research and improvements are conducted on the existing problems, and a protective cover fixing tool is provided, which has a reasonable structural design, integrates good protection effect, does not require manual follow-up, and has a good buffering effect, reduces manpower and material resources, and greatly improves work efficiency. The purpose is to solve the problem and improve the practical value through this technology. Utility Model Content

In addition, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0022] Reference Figure 1-3 The utility model provides an embodiment: a protective cover fixing tool, including an L-shaped plate 1, a first connecting rod 2 is fixedly connected to one side of the L-shaped plate 1, a second connecting rod 3 is fixedly connected to one side of the first connecting rod 2, a screw 4 is fixedly connected to the other side of the L-shaped plate 1, a mounting plate 5 is fixedly connected to the bottom of the screw 4, a nut 6 is fixedly connected to the top of the screw 4, a cylinder 7 is movably connected to the bottom of the screw 4, a fixing hole 8 is arranged inside the cylinder 7, an anti-skid layer 9 is fixedly connected to one side of the fixing hole 8 to prevent the protective cover from falling off due to the overly smooth surface of the cylinder 7, an inner cavity 10 is arranged inside the cylinder 7, a contraction cavity 11 is arranged on one side of the inner cavity 10, a reset spring 12 is fixedly connected to the contraction cavity 11 to disperse the pressure between the cylinder 7 and the protective cover to avoid damage, and a buffer block 13 is fixedly connected to the bottom of the anti-skid layer 9.

[0023] Specifically, the contraction cavity 11 and the return spring 12 form a buffer structure, and the buffer structure is in two groups. The buffer structure is located on both sides of the cylinder 7 to effectively disperse the fixed pressure between the cylinder 7 and the protective cover to avoid damage to the protective cover.

[0024] Specifically, the inner wall of the inner cavity 10 is provided with an internal thread, and the inner diameter of the inner cavity 10 matches the outer diameter of the screw rod 4 .
