Abstract
The switch-type fast pipe twist has appearance of available American one and has self-slide arc opening, concealed automatic clamping and repositioning system, lock wheel-controlling switch system and opening limiter. Only once push of the button switch can complete a series of regulation including rotating lock wheel, opening mouth, clamping workpiece, locking mouth and closing mouth in one second. The technological breakthrough makes the present invention realize automation and programmed operation.
Description
The present invention relates to a kind of fast pipe twist that uses the rapid clamping operation of switch.
Pipe vice has long history, uses the female jaw of regulating of pincers, and slow motion is not easy to clamp pipe fitting again, countless reform schemes are arranged recent decades both at home and abroad, as the 85203825 self-adjustable bulldog wrenches of China, 94225040.0 quick pipe wrenches etc., these designs are difficult to achieve success.
Purpose of the present invention will provide a kind of simple structure exactly, the automation switching mode pipe wrench of easy to manufacture, sturdy and durable, fast and flexible.
The object of the present invention is achieved like this: new departure has kept the profile of former American pattern pipe pliers, is provided with self-skating type arc subtended angle jaw, built-in automatic clamping resetting system, the spacing shelves of switch lock cranking wheel control system and jaw.Built-in automatic clamping resetting system is made up of moving caliper groove, back-moving spring, the pincers cover that has reset passages and guard shield plate, the front end of guard shield plate has a through hole, the guard shield plate is fixed on a side of moving caliper, the rear end of guard shield plate is an opening, in back-moving spring penetrates space between guard shield plate and moving caliper groove from opening part, use bolt that the front end of spring is fixed on the through hole of guard shield plate, moving caliper one side forms the thickening sidewall.Reset passages (or moving caliper one side is arc, the curved wall with reset passages) is offered in the centre, makes the moving caliper that the guard shield plate is housed be easy to pass pincers covers, and is free unimpeded, and the rear end of back-moving spring is fixed on the after-frame of pincers cover.Release knob, crossbeam and snap that centre bore was taken turns, had to the switch lock cranking wheel control system by lock are formed, the lock wheel body is that the female both sides of pincers internal thread is pushed away flat opening the light, pushing away flat width size of opening the light just in time can make moving caliper freely pass through, the lock wheel is gone up the screw that penetrates is set, the release knob that will have centre bore is fastened on the screw, be installed with snap on the crossbeam, use bolt crossbeam to be fixed on pincers and put, make the snap movable end penetrate the centre bore of release knob by screw.At last, install spacing shelves additional at mounted moving caliper tail end, the restriction moving caliper is deviate from from the pincers cover.
The present invention is owing to designed arc subtended angle jaw, built-in automatic clamping resetting system, switch lock cranking wheel control system, thereby lock wheel is rotated---open jaw---clamp workpiece---locking jaw---it only is to touch press button that this serial adjustment process of closed jaw becomes, in 1 second, all finish, realized automation, sequencing, rapid, technical had a breakthrough development.
Concrete structure of the present invention is provided by following examples and accompanying drawing thereof.
A kind of quick pipe spanner wrench controlled by button schematic appearance that Fig. 1 proposes for the present invention.
Fig. 2 is built-in automatic clamping resetting system schematic diagram.
Fig. 3 is a switch lock cranking wheel control system schematic diagram.
Shown in Fig. 1 a, b, c, (1) is fixed clamp, and (2) are moving caliper, and (3) are the pincers cover, and (4) are the lock wheel, and (5) are the guard shield plate, and (6) are release knob, and (21) are the spacing shelves of jaw.New pipe wrench overall appearance has kept the profile of former American pattern pipe pliers, and different is that an arc subtended angle θ is arranged at the jaw place, and the size of θ can freely be selected.
As shown in Figure 2, (7) are the moving caliper groove, and (8) are back-moving spring, and (9) are guard shield plate through hole.The guard shield plate is fixed on the moving caliper, the rear end is an opening, in spring penetrates space between guard shield plate and moving caliper groove from open rearward end, the front end of spring is fixed on the through hole, pincers cover one side forms thickening sidewall (10), the centre has reset passages (11), and the rear end of spring can be fixed on the screw (12) of pincers cover after-frame.
Shown in Fig. 3 a, the lock wheel body is made by the pincers mother, and (13) be internal thread, and (14) are the moving caliper passage open the light, internal thread is pushed away flat, pushes away flat width size moving caliper is freely passed through.(15) be the screw that penetrates on the lock wheel, 3b is the profile of (5), and its outward appearance is a bolt, but on the screw rod centre bore is arranged (16), and release knob can be fastened on penetrating on the screw of lock wheel.(17) be crossbeam, (18) are snap, and crossbeam uses bolt to be fixed on pincers by screw (20) and puts, and makes snap movable end (19) penetrate the centre bore of release knob.
During use, only need the light release knob of dialling downwards, arc subtended angle θ is aimed at pipe fitting downward press, jaw is held pipe fitting automatically in the month, and the trip switch button just can rotate the work of pincers handle.Since this pipe wrench superior performance, and simple in structure, long-range DEVELOPMENT PROSPECT and world's great market are arranged.
