The specific embodiment
The exemplary embodiment that Fig. 1 to Fig. 6 shows will be described below.
Fig. 1 shows the perspective view of welding torch 1.Shown in welding torch have handle 2, it is formed by last housing department 3 and lower casing portion 4.Gooseneck 6 begins to extend from the leading edge of handle, until spray nozzle device 7.The back edge of handle is provided with rotatable portion 8, and its guiding welding hose (not shown) enters handle.Retaining mechanism 11 is installed on the leading edge of handle, and only the articulation 10 of retaining mechanism 11 in the drawings as seen.Control current switch 9 is arranged under the handle.
The welding torch of shown type is applicable to water-cooled or air cooling.
The inside of handle 2 is presented among Fig. 2 and Fig. 3.Can see how Connection Element 5 is installed, and it is connected with gooseneck 6 securely.The welding hose (not shown) is passed handle by the rotatable portion 8 that arranges backward on handle, arrive Connection Element 5 by a plurality of couplings that are provided with for welding wire, gas, cooling air or cooling water.
The sectional view of Fig. 3 shows the retaining mechanism 11 with articulation 10, bearing 22 and cavity 12.Spring or rubber ring (not shown) as O type circle, are arranged in the cavity to absorb any manufacturing tolerance that may exist between the parts in the retaining mechanism.Spring or rubber ring have guaranteed that pressure will be present between articulation 10 and the Connection Element 5 always, and this will promote Connection Element 5 backward in the handle inboard.
Fig. 4 shows the perspective view of Connection Element 5.Can see how Connection Element is configured to cylindrical member, and it can rotate in handle.It can also be seen that at one end, it is provided with gear ring 13,15, it extends on whole circumference around cylindrical member.Yet gear ring also can be divided into a plurality of fragments 15 with optional tooth number.
The tooth pitch D that gear ring 13 or fragment 15 advantageously are configured with corresponding to 7 teeth on 90 ° the circular sector (sees Fig. 4 a).The adjusting position that guarantees sufficient amount like this is to satisfy the adjusting needs of all reality.
The length of tooth from the top to bottom is chosen as and makes this length be at least 3mm, yet also can select other length.
Fig. 5 is the perspective view of the structure of handle 2 front portions.Shown in lower casing portion 4 have a half-ring gear 14 or gear ring fragment 16.Last housing department 3 is provided with a half-ring gear 14 or gear ring fragment 16 equally.Make tooth with tooth pitch D corresponding to 7 teeth on 90 ° the circular sector.The adjusting position that guarantees sufficient amount like this is to satisfy the adjusting needs of all reality.
The length of tooth from the top to bottom is chosen as and makes this length be at least 3mm, yet also can select other length.
The tooth of gear ring 13,14 is arranged to unified profile of tooth, makes it accurately to cooperate mutually.But they also can be arranged to such shape, have to the flank inaccuracy same slope, make to be forced into a time-out when gear ring, these teeth can be before tooth top and tooth root contact with each other wedging to together.This can cause firmly connecting and very close to each other.
Gear ring 14 or gear ring fragment 16 be arranged so that teeth directional leading to and towards the leading edge 21 of handle.The gear ring 13 of connection element 5 and gear ring fragment 15 are arranged so that behind the teeth directional guiding and away from gooseneck 6.This has guaranteed to spur Connection Element and handle is bonded with each other with disengaging, and connection element can be rotated one or more positions.
Engage for removing, be necessary at first to discharge retaining mechanism 11.
Retaining mechanism comprises the outside friction lock 19 on the housing department 3,4 that is positioned at handle.Friction lock is extended obliquely with respect to the center line parts transversely and the part of handle.On the lateral part, friction lock is provided with at least one rib 20, the articulation in its locking operation position.Rake ends at projection 23, and it prevents that articulation from coming off. Housing department 3,4 all is provided with outside friction lock 19.
In addition, as shown in Figure 6, retaining mechanism comprises articulation 10, and it is provided with inside lock projection 18, and it is constructed to be permeable to the friction lock 19 on the engages handle.
When articulation 10 was rotated, retaining mechanism 11 was opened, and the inclined degree of friction lock has guaranteed that articulation is shifted in the axial direction, is used to spur gear ring so that the space that its disengaging is bonded with each other with generation under the situation of little rotation.In advantageous embodiments, the value that displacement is adopted is for being at least 3mm rotating under at least 15 ° the situation, but also can select other numerical value, as, rotate the 5mm that is shifted under 17 ° the situation.
