Abstract
Description
Technical Field
[0001] The utility model relates to the field of oxyacetylene welding accessories, in particular to a gas cylinder wrench used for oxyacetylene welding. Background Art
[0002] Oxyacetylene welding is a welding method that uses the flame generated by the combustion of acetylene and oxygen as a heat source to melt the local workpiece and welding wire to form a molten pool, so that they can achieve interatomic bonding. Oxyacetylene cutting is a method that uses the large amount of heat energy released when oxygen and acetylene burn to generate a high-temperature flame, and uses high-speed cutting oxygen to burn and blow away the metal at the cut. The combustion-supporting gas for oxyacetylene welding and cutting is mainly oxygen, and the combustible gas is mainly acetylene. Oxyacetylene welding and cutting equipment usually includes a gas supply system (including oxygen cylinders, acetylene cylinders, oxygen pressure reducers, acetylene pressure reducers, acetylene flashback preventers and oxygen-acetylene hoses), welding guns, cutting guns and oxyacetylene wrenches. Usually, oxyacetylene wrenches are used independently. Oxygen wrenches use adjustable wrenches. To disassemble and assemble oxygen pressure reducers, oxygen hoses, and open and close gas cylinders, the size of the adjustable wrench must be adjusted multiple times to open, close, and disassemble them one by one. However, to disassemble and assemble acetylene pressure reducers, acetylene hoses, and open and close gas cylinders, separate acetylene wrenches are required, which are inconvenient to carry together, are cumbersome to operate, and reduce work efficiency. Utility Model Content
[0003] The technical problem to be solved by the utility model is to provide a gas cylinder wrench for oxyacetylene welding, which can quickly realize the opening and closing operations of oxygen cylinders and acetylene cylinders when using oxygen-acetylene welding and cutting.
[0004] The utility model solves the technical problem by adopting the following technical scheme: a gas cylinder wrench for oxyacetylene welding comprises a wrench handle portion, one end of which is provided with a wrench head portion, the wrench head portion is provided with a wrench bayonet, the wrench bayonet portion comprises, from outside to inside, a first bayonet port matched with an oxygen pressure reducer air inlet interface nut, a second bayonet port matched with an oxygen pressure reducer and an acetylene pressure reducer air outlet interface nut, and a third bayonet port matched with an oxygen cylinder switch valve, the opening sizes of the first bayonet port, the second bayonet port and the third bayonet port are reduced in sequence, a first transition edge is provided between the first bayonet port and the second bayonet port, a second transition edge is provided between the second bayonet port and the third bayonet port, and the other end of the wrench handle portion is provided with a four-corner sleeve matched with an acetylene cylinder switch valve and an acetylene pressure reducer fence thimble.
[0005] Furthermore, the first transition edge is V-shaped, and the first angle of the first transition edge is 120°.
[0006] Furthermore, the second transition edge is V-shaped, and the second angle of the second transition edge is 120°.
[0007] Furthermore, the other end of the wrench handle is a U-shaped notch, and the four-corner sleeve can be rotatably arranged in the U-shaped notch.
[0008] Furthermore, the four-corner sleeve is arranged in the U-shaped notch through a hinge.
[0009] The beneficial effect of the utility model is that in actual use, in view of the need for continuous operation of multiple gas cylinder nuts and ejector pins, the solution integrates the original independent wrenches into one gas cylinder wrench, and the specific method is to cleverly set the opening sizes of the first bayonet, the second bayonet and the third bayonet to decrease in sequence, thereby realizing the integration of multiple wrench functions. The utility model is particularly suitable for oxyacetylene welding. BRIEF DESCRIPTION OF THE DRAWINGS
[0010] Figure 1 It is a schematic diagram of the utility model.
[0011] Figure 2 It is a schematic diagram of the wrench bayonet of the utility model.
[0012] Figure 3 It is a schematic diagram of a four-corner sleeve of the utility model.
[0013] Marked in the figure: wrench handle 1, U-shaped notch 2, four-corner sleeve 21, wrench head 3, first bayonet 31, first transition edge 311, first angle 312, second bayonet 32, second transition edge 321, second angle 322, third bayonet 33. DETAILED DESCRIPTION
[0014] The utility model is further described below in conjunction with the accompanying drawings.
[0015] like Figure 1 , Figure 2 , Figure 3 The gas cylinder wrench for oxyacetylene welding shown in the figure comprises a wrench handle 1, one end of which is provided with a wrench head 3, and the wrench head 3 is provided with a wrench bayonet, which is mainly composed of a first bayonet 31, a second bayonet 32 and a third bayonet 33. In actual use, since it is necessary to operate the oxygen pressure reducer air inlet interface nut, the oxygen pressure reducer and acetylene pressure reducer air outlet interface nut, and the oxygen cylinder switch valve, which are three objects with different sizes and shapes, respectively, as shown in FIG. Figure 1 As shown, the opening sizes of the first bayonet 31, the second bayonet 32 and the third bayonet 33 are designed to decrease successively, thereby forming a stepped bayonet form that gradually decreases from the outside to the inside, thereby achieving the effect of integrating the three buckles into the wrench bayonet of the wrench head 3, and making actual operation more convenient.
[0016] In addition, a square sleeve 21 matching the acetylene bottle switch valve and the acetylene pressure reducer fence pin is arranged in the U-shaped notch 2 at the other end of the wrench handle 1. The square sleeve 21 can rotate, but is always limited in the U-shaped notch 2. Generally, the square sleeve 21 can be rotatably arranged in the U-shaped notch 2 by a hinge connection. The existing square sleeve 21 matching the acetylene bottle switch valve and the acetylene pressure reducer fence pin can be used.
[0017] As a structural optimization of the first transition edge 311 of the wrench bayonet, the first transition edge 311 may be selected to be V-shaped, and the first angle 312 of the first transition edge 311 is 120°. Figure 2 As shown, the opening of the first bayonet 31 is larger than the second bayonet 32, and there is a first transition edge 311 connecting the two. The first transition edge 311 preferably has an angle of 120°, which can not only guide the nut to be operated from the first bayonet 31 to the second bayonet 32 smoothly during use, but also optimize the stress distribution between the first bayonet 31 and the second bayonet 32 to prevent cracks or even damage caused by stress concentration. Based on the same concept, the second transition edge 321 can also be preferably V-shaped, and the second angle 322 of the second transition edge 321 is 120°.
[0018] In actual use, the operator only needs to carry a gas cylinder wrench to perform corresponding operations on the oxygen pressure reducer air inlet interface nut, the oxygen pressure reducer and acetylene pressure reducer air outlet interface nuts, the oxygen cylinder switch valve, and the acetylene cylinder switch valve and acetylene pressure reducer fence thimble, thereby greatly improving the operation efficiency.
