Abstract
The utility model discloses a fast G shape clamp, which comprises a clamp body, a spring, a clamp block and a screw, wherein, the clamp block is hinged with the screw, the clamp body is G-shaped, and one end of the clamp body is connected with the screw in a clearance fit form. The utility model is characterized in that the fast G shape clamp also comprises an open-closed-open screw nut which comprises a tooth block and a handle made integrally with the tooth block, wherein, the appearance of the tooth block is a polygon plate. The upper part of the tooth block is provided with a section of screw threads and the bottom part of the tooth block is provided with an inclined plane. One end of the tooth block is provided with a round blind hole and the other end of the tooth block is connected with the handle. The clamp body is provided with an incline blind hole matched with the tooth block of the open-closed-open screw nut. The tooth block is inserted into the blind hole. One end of the spring is inserted into a round blind hole of the tooth block and the other end of the spring is connected with the clamp body. The screw threads on the top surface of the tooth block and the screw form a screw thread kinematic pair. When the utility model is used, the screw model can be fast moved forwards or backwards. The fast G shape clamp has the advantages simple structure, convenient use and high work efficiency.
Description
Technical field
The utility model relates to a kind of clamping tool, and especially a kind of quick G-shaped folder belongs to the hardware ﹠ tools technical field.
Background technology
G word folder is widely used in industrial production as a kind of clamping tool, the general structure of using now that adopts of G word folder is, screwed hole on screw rod and the clamp constitutes the screw pair, because the G word of this structure folder can not the fast moving screw rod, so operating efficiency is lower.
Find by retrieval, existing G word folder also has another kind of structural shape, by application number is that 022614052 utility model patent is disclosed, it is made up of clamp, screw rod, spring, block teeth, cover plate, button etc., constitute the screw pair by block teeth and screw rod, can live button with hand during use makes block teeth overcome spring force and screw rod is separated, thereby can the fast moving screw rod, in case release-push, the screw thread of block teeth then is meshed with screw flight again, and therefore the G word of this structure folder operating efficiency is higher.But its structure is comparatively complicated, again because no matter be when pressing from both sides clamping work pieces with the G word, still with G word folder from the workpiece dismounting down, all will live button ability fast moving screw rod with hand, so operate cumbersome.
Summary of the invention
The purpose of this utility model is that the G word at prior art presss from both sides existing deficiency, proposes a kind of quick G-shaped folder simple in structure, easy to use.
To achieve these goals, quick G-shaped folder of the present utility model, comprise clamp, spring, fixture block and screw rod, described fixture block and screw rod are hinged, described clamp is c-shaped, one end and described screw clearance are connected, it is characterized in that: also comprise a deciliter nut, described deciliter nut comprises block teeth and makes the handle of one with described block teeth, described block teeth profile is the polygon plates, and its top is shaped on one section screw thread, bottom and is shaped on that an inclined-plane, an end are shaped on circular blind hole, the other end links to each other with described handle; Be shaped on the inclination blind hole that is complementary with deciliter nut block teeth on the described clamp, described block teeth are inlaid in this blind hole; One end of described spring is inlaid in the circular blind hole of described block teeth, and the other end is connected mutually with described clamp, and the screw thread on described block teeth top and described screw rod constitute the screw thread kinematic pair.
The further improvement of the utility model structure is:
What a) described screw thread kinematic pair adopted is trapezoidal thread.
B) arc surface is made in the end face of described block teeth and bottom surface.
C) handle of described block teeth body in the form of sheets, the angle of the bottom surface of this plates handle and block teeth is an acute angle.
When using the utility model clamping work pieces, can directly screw rod be pushed away forward, after the block teeth of deciliter nut are subjected to the active force of screw rod, when the clamp blind hole moves, also, make block teeth and screw rod break away from engagement with respect to the junction rotation of block teeth inclined-plane and bottom surface, screw rod just can move forward fast, touch until fixture block and to be held workpiece, this moment, block teeth under the effect of spring force returned to the state that is meshed with screw rod again, and then rotary screw just can clamp workpiece.When needs when workpiece is dismantled, earlier screw rod is rotated backward about 2 circles, use the handle of hand deciliter nut again, block teeth just break away from engagement with screw rod, so just can apace screw rod be pulled back.Obviously, compare ingenious, simple in structure, easy to use, the high efficiency of the utility model design with the G word folder of prior art.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is the structural representation of the utility model embodiment one.
Fig. 2 is the front view of part 5 among Fig. 1.
Fig. 3 is the left view of Fig. 2.
The specific embodiment
The nonrestrictive a kind of embodiment that provides the utility model to relate in the accompanying drawing, the utility model will be further described below in conjunction with embodiment.
As Fig. 1～shown in Figure 3, the quick G-shaped folder of present embodiment, by C clamp body 1, screw rod 3, fixture block 2, tommy bar 4, deciliter nut 5, spring 7 form, the screw thread of screw rod 3 is trapezoidal thread, fixture block 2 is hinged with screw rod 3, clamp 1 is connected with screw rod 3 matched in clearance, and tommy bar 4 is connected with screw rod 3; Deciliter nut 5 contains block teeth 51 and makes the handle 52 of one with block teeth 51, block teeth 51 profiles are the polygon plates, its top is shaped on one section trapezoidal thread, bottom and is shaped on an inclined-plane, end face and bottom surface and makes that arc surface, an end are shaped on circular blind hole, the other end links to each other with handle 52, handle 52 is body in the form of sheets, the angle of the bottom surface of it and block teeth 51 is an acute angle, handle 52 and bar are pulled 4 and approximately are parallel to each other more convenient operation like this; Be shaped on the inclination blind hole 6 that the block teeth 51 with deciliter nut 5 are complementary on the clamp 1, block teeth 51 are inlaid in this blind hole 6; One end of spring 7 is inlaid in the circular blind hole of block teeth 51, and the other end is connected mutually with clamp 3, and the thread segment on block teeth 51 tops and screw rod 3 constitute the screw thread kinematic pair.
During with the present embodiment clamping work pieces, earlier clamp 1 is placed the clamping position of workpiece, again screw rod 3 is pushed away forward, after the block teeth 51 of deciliter nut 5 are subjected to the active force of screw rod 3, when clamp 1 blind hole 6 moves, also with respect to the lower bevel of block teeth and the junction rotation of bottom surface, make block teeth 51 and screw rod 3 break away from engagement, screw rod 3 just can move forward fast like this, touch the workpiece that is held until fixture block 2, this moment, block teeth 51 under the effect of spring force returned to the state that is meshed with screw rod 3 again, and then rotary screw 3 just can clamp workpiece; If will dismantle following time from workpiece, earlier screw rod 3 is rotated backward about 2 circles, use the handle 52 of hand deciliter nut 5 again, block teeth 51 just break away from engagement with screw rod 3, so just can apace screw rod 3 be pulled back.
From as can be known above-mentioned, the utility model structure is very simple, manufacturing cost is lower, and is easy to use, fast.
