Abstract
The invention relates to the technical field of manual hardware tools. According to a self-adjustable water pump clamp, an opening is formed in a sliding clamp body; a sliding groove is formed in a fixed clamp body; the fixed clamp body passes through the opening in the sliding clamp body; a pin shaft penetrates through the sliding groove in the vertical direction of the opening and is connected with the fixed clamp body; a ratchet-shaped groove is formed in one side face of the sliding groove of the fixed clamp body; a ratchet wheel rotation piece is connected to the pin shaft in the sliding groove; a pressing spring is arranged on a ratchet wheel; an unlocking pin is arranged on the sliding clamp body and rotates around the pin shaft in a ratchet wheel groove to drive the ratchet wheel to rotate; a threaded hole is formed in the upper part of the front part of a handle of the fixed clamp body; a horizontal included angle between the central line of the threaded hole and the handle of the fixed clamp body is 100-120 degrees; a screw is mounted on the threaded hole; a fixed sleeve is fixedly arranged on the screw; a movable sleeve is connected with the fixed sleeve; a screw cover is fixedly arranged on the movable sleeve; the movable sleeve can move up and down on the fixed sleeve; the screw cover is connected with the screw through a spring; the pitch of the spring is equal to the thread pitch on the screw and the screw cover. The self-adjustable water pump clamp is reasonable in design, simple in structure, easy to manufacture, low in cost, convenient to use and operate, time-saving and labor-saving.
Description
Technical field
The present invention relates to the technical field of five metals hand-operated tools, specifically a kind of self-adjusting water pump clamp.
Background technology
Water pump pliers on market is mostly made up of fixed caliper, slip caliper and bearing pin, according to the position of the size adjustment slip caliper of workpiece during use, realizes the change of caliper opening amount size.In use, by repeatedly adjusting the position of slip caliper, change opening amount size, to adapt to the needs clamped.Its troublesome poeration, uses inconvenience, and efficiency is low.Have at present on caliper, to be provided with that resilient movement device solves the problem, generally on caliper, be provided with spring cap, spring, screw, unstable properties during use, the easy lateral bending of spring causes motion smooth, affects the service life of pliers.
Summary of the invention
The object of the invention is the deficiency in order to solve above-mentioned technology, provide a kind of reasonable in design, structure simple, easily manufactures, easy to use, caliper can fast, the self-adjusting water pump clamp of stable movement.
The present invention solves the technical scheme that above-mentioned technical deficiency takes: a kind of self-adjusting water pump clamp, be provided with fixed caliper, slip caliper, slip caliper there is opening, fixed caliper there is chute, fixed caliper is by the upper shed of slip caliper, there is bearing pin to run through chute in the vertical direction of opening and be connected and fixed caliper, there is ratchet-shaped groove chute one side of fixed caliper, bearing pin in chute is connected with pawl wheel part, ratchet there is stage clip, slip caliper there is latch, latch is rotated around bearing pin and is driven pawl wheel in ratchet groove, it is characterized in that fixed caliper 1 handle front upper portion is provided with screwed hole, the horizontal sextant angle of screwed hole center line and fixed caliper handle is 100 °-120 °, screwed hole is provided with screw, fixed cover is fixed on screw, movable sleeve is connected with fixed cover, screw cap is fixed on movable sleeve, be actively set on fixed cover and can move up and down, be connected by spring between screw cap with screw, the pitch of spring is identical with the thread pitch on screw cap with screw.
The present invention is reasonable in design, and structure is simple, easily manufactures, cost is low, use, easy to operate, time saving and energy saving, and spring is connected between screw cap and screw, movable sleeve and the opposing parallel stable movement of fixed cover energy.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Mark in figure: 1, fixed caliper, 2, slip caliper, 3, ratchet, 4, latch, 5, bearing pin, 6, stage clip, 7, screw cap, 8, spring, 9, movable sleeve, 10, fixed cover, 11, screw.
Detailed description of the invention
As shown in Figure 1, a kind of self-adjusting water pump clamp, be provided with fixed caliper 1, slip caliper 2, slip caliper 2 there is opening, fixed caliper 1 there is chute, fixed caliper 1 is by slip caliper 2 upper shed, there is bearing pin 5 to run through chute in the vertical direction of opening and be connected and fixed caliper 1, there is ratchet-shaped groove chute one side of fixed caliper 1, on bearing pin 5 in chute, there is ratchet 4 one end, ratchet 3 there is stage clip 6, slip caliper 2 there is latch 4, latch 4 is rotated around bearing pin 5 and is driven ratchet 3 to rotate in ratchet groove, its fixed caliper 1 handle front upper portion is provided with screwed hole, the horizontal sextant angle of screwed hole center line and fixed caliper handle is 100 °-120 °, screwed hole is provided with screw 11, fixed cover 10 is fixed on screw 11, movable sleeve 9 is connected with fixed cover 10, screw cap 7 is fixed on movable sleeve 9, movable sleeve 9 can move up and down on fixed cover 10, , be connected by spring 8 between screw cap 7 with screw 11, the pitch of spring 8 is identical with the thread pitch on screw cap 7 with screw 11.
During work, fixed caliper 1 and slip caliper 2 relative motion is first made to open, after being placed in holding workpiece position, hold caliper housing pin lid 7, screw cap 7 promotes slip caliper 2 and travels forward, after reaching clamped position under the resilient force of spring 8, when gripping caliper further, under power of being in one's hands effect, two calipers continue relative motion, and spring 8 is compressed again, movable sleeve 9 and fixed cover 10 relative movement, make it highly reduce, two caliper spaces strengthen, and hand grip force is increased.Promote slip caliper 2 by screw cap 7 to move in the process transferring to and being compressed by slip caliper 2, it moves steadily, not lateral bending, fluent, time saving and energy saving, and operating efficiency is high, and clamping effect is good.
Because the pitch of spring 8 is identical with the thread pitch on screw cap 7 with screw 11, spring together with the easy turn-knob of screw thread, and has the feature of difficult drop-off, movable sleeve and fixed cover is linked together securely.Under external force, relative movement can be realized between movable sleeve and fixed cover, utilize spring can promote caliper swimmingly to move and make jaw close holding workpiece, two calipers understand relative closing motion after clamping workpiece, promote spring-compressed, thus the distance realized between two calipers reduces, reach the effect of holding workpiece of can exerting oneself.
