Abstract
The utility model provides a spanner for cutting and welding, which comprises a movable spanner head [1] and a handle [2]. A convex column body [3] is positioned on a lateral wall at the end section of the handle [2]; a stepped inner square hole vertical to the handle is made on the column body; an inner square hole [5] at the convex side coordinates with an ethane tank; an inner square hole [4] at the other side coordinates with an oxygen tank. Therefore, the utility model can complete all the operations including the open and close of ethane and oxygen tank valve as well as the assembly and disassembly of reducing valve with only one spanner. Besides, the utility model has the advantages of portable tools, convenient and labor saving in operation, simple structure and easy processing.
Description
Technical field the utility model relates to the tool wrench that is used to open and close acetylene valve and loading and unloading pressure-reducing valve.
Background technology is present, when using acetylene gas and oxygen to cut or weld, usually to open and close the operation of acetylene and oxygen cylinder valve and loading and unloading pressure-reducing valve, the operation that wherein opens and closes acetylene cylinder valve and loading and unloading pressure-reducing valve thereof is mainly carried out with T-shaped acetylene spanner, have the interior four jiaos of square holes that cooperate with the acetylene valve on this wrench body, because handle is T-shaped with body and is connected, make the arm of force length limited of handle, have only about 80mm, require great effort during opening/shutting valve, often cause the acetylene cylinder valve closing tightly not form gas leakage, set off an explosion easily.And the operation that opens and closes oxygen cylinder valve and loading and unloading pressure-reducing valve thereof is normally carried out with monkey wrench, because the oxygen cylinder pressure-reducing valve is fastenedly connected with hex nut and bottle usually, and the bottle drain tap is four jiaos of square nuts, need regulate monkey wrench repeatedly, operate more loaded down with trivial detailsly, otherwise must hocket with the spanner that acetylene spanner and another one are twisted hex nut.
Summary of the invention is in order to solve the unhandy problem of above-mentioned keying acetylene and oxygen cylinder valve and loading and unloading pressure-reducing valve, and the utility model provides a kind of cutting welding use spanner, and is not only easy to operate, and all operations spanner of need only, is easy to carry.
A kind of cutting welding of the utility model spanner, on the sidewall of the handle end of monkey wrench, be provided with projection cylinder, have the step-like interior square tube hole vertical with handle on the cylinder, the interior square hole of a protruding side cooperates with the acetylene cylinder valve, and square hole cooperates with oxygen cylinder valve in the opposite side.When opening and closing the operation of acetylene cylinder valve and loading and unloading pressure-reducing valve thereof, carry out with the interior square hole that cooperates with the acetylene cylinder valve on the handle, because the handle of monkey wrench is longer, have about 230mm, more laborsaving during opening/shutting valve, the acetylene cylinder valve closing is tighter, can not leak gas.And when opening and closing the operation of oxygen cylinder valve and loading and unloading pressure-reducing valve thereof, the interior square hole that cooperates with oxygen cylinder valve that opens and closes on the oxygen cylinder valve door handle carries out, the hex nut of oxygen cylinder pressure-reducing valve is operated with monkey wrench, and monkey wrench only need be regulated once, and a spanner can be finished whole operations.
Because the utility model is on the basis of monkey wrench, on handle, set up an interior square hole spanner identical with acetylene spanner function, only need a spanner can finish all operations of keying acetylene and oxygen cylinder valve and loading and unloading pressure-reducing valve thereof, instrument is easy to carry, and operate more convenient laborsaving, simple in structure, be easy to processing.
Description of drawings Fig. 1 is the utility model structural representation.
Fig. 2 is the vertical view of spanner shown in Figure 1.
The specific embodiment is by illustrated in figures 1 and 2, a kind of welding spanner of the utility model is a monkey wrench, form by adjustable movable jaw of opening [1] and handle [2], handle [2] the sidewall of end be provided with projection cylinder [3], have the step-like through hole vertical on the cylinder [3] with handle [2], this through hole is foursquare interior square hole, and the interior square hole [5] of a protruding side cooperates with the acetylene cylinder valve, the wide 10mm in hole; Square hole [4] cooperates the wide 8mm in hole in the opposite side with oxygen cylinder valve.Because interior square hole is a through hole, can be used for hanging.
Claims (2)
1, a kind of cutting welding spanner, form by adjustable movable jaw of opening [1] and handle [2], the sidewall that it is characterized in that the end of handle [2] be provided with projection cylinder [3], have the interior square hole of the stairstepping through hole vertical on the cylinder with handle, the interior square hole [5] of projection one side cooperates with the acetylene cylinder valve, and square hole [4] cooperates with oxygen cylinder valve in the opposite side.
2, spanner according to claim 1 is characterized in that the Kong Kuanwei 10mm of the interior square hole [5] of a described protruding side; The Kong Kuanwei 8mm of square hole [4] in the opposite side.
