Quick clamp mechanism
Technical Field
The utility model relates to a technical field of anchor clamps structure, in particular to quick clamp mechanism.
Background
The current technical background is as follows: most of the existing clamps are already used as products, and are sold on manufacturing platforms of Mi Saimi and other large standard parts. Most of the prior art is made of sheet metal parts, the strength and toughness of the clamp are poor, and the clamp is easy to break, deform and damage on parts needing stress during clamping. In addition, chinese patent publication No. CN110340819a discloses a manual clamp, which includes a clamp base, a connecting plate, a control plate, a rotating plate, a pressure head bolt, an upper supporting backup plate, a lower supporting backup plate, an adjusting nut, and a cylindrical spring. Wherein, the front end of the rotating plate is provided with a strip-shaped mounting groove. The upper and lower supporting plates are symmetrically arranged at the upper and lower sides of the mounting groove. The pressure head bolt sequentially passes through the upper supporting backup plate, the mounting groove and the lower supporting backup plate. The adjusting nut is sleeved on the pressure head bolt and arranged right above the upper backup plate. The columnar spring is also sleeved on the pressure head bolt and always abuts against the position between the pressure head and the lower abutting plate, when the connecting plate rotates clockwise, the operation plate rotates anticlockwise to drive the pressure head to move downwards to compress a workpiece, the pressure of the product is controlled, different pressure control is realized by disassembling and replacing the columnar springs with different rigidity coefficients, when the elastic coefficient of the spring changes, the pressure of the product is difficult to guarantee, the product is easy to damage due to overvoltage, the product cannot be completely fixed when the pressure requirement cannot be met, and the pressure is controlled by replacing the spring, so that the waste of product resources is easy, and the replacement is troublesome. And Chinese patent with publication number CN209868353U discloses a clamp, which comprises an operating handle rod hinged on a support through a first hinge shaft, and a swing rod hinged on the support through a second hinge shaft.
SUMMERY OF THE UTILITY MODEL

The utility model adopts the technical proposal that: the utility model discloses a support, handle, first connecting rod, second connecting rod and compact heap, the handle has connecting portion and the portion of gripping, the one end of connecting portion with the support is articulated, the other end of connecting portion with first connecting rod is articulated, first connecting rod is kept away from the one end of connecting portion with the second connecting rod is articulated, the compact heap is located one end of second connecting rod is served, the second connecting rod is kept away from the one end of compact heap with the support is articulated, be equipped with the cooperation on the support and locate the braking portion and the cooperation of first connecting rod activity orbit below are located the braking pin of second connecting rod activity orbit one side.
Further, the connecting part and the holding part are of an integrally formed structure.
Furthermore, be equipped with fixed rod, first mounting and second mounting on the second connecting rod, the fixed rod passes through the bolt and installs on the second connecting rod just the fixed rod runs through in proper order first mounting, the second connecting rod and the second mounting, the compact heap with the fixed rod is connected.
Further, the support, first connecting rod, all seted up the through-hole on the second connecting rod, be equipped with hinge assembly on the through-hole, hinge assembly includes rotation bolt, nut and copper sheathing, rotation bolt runs through the through-hole and with nut screw-thread fit, the copper sheathing is established on the rotation bolt and be located in the through-hole.
Furthermore, the outer side end of the support extends to an upward-bent installation part, and the connecting part is in running fit with the installation part.
The utility model discloses following beneficial effect has:
1. when the clamp of the device is in an open state, the handle is rotated forwards, the handle drives the first connecting rod and the second connecting rod to rotate, so that the pressing block moves from top to bottom, the upper part of a product is pressed by the pressing block, the lower part of the product is limited, supported and fixed by an external workpiece, the first connecting rod is driven to rotate downwards in the forward rotating process of the handle, the first connecting rod is limited by the braking part and does not move downwards when the product is pressed due to the arrangement of the braking part, the clamp of the device is already in a dead point position, the clamp cannot be pushed even if the handle is pushed upwards with force, and the pressing block is already in a pressing state at the moment, so that the product can be effectively prevented from being damaged and the pressing can be guaranteed to be in place; when the clamp does not need to clamp a product, namely, the clamp needs to be loosened, the handle is held by hand to pull backwards, the pressing block is separated from the pressed product, and the clamp is in a completely loosened state when the second connecting rod touches the brake pin.
2. The connecting part and the holding part are of an integrally formed structure, so that the connecting part and the holding part are easy to machine and form and high in strength, and the clamp of the device is integrally formed by adopting a casting or carbon steel machining, so that the clamp can bear large force when a product needing stress is compressed.
3. The outside end of support extends to the installation department of upwards bending, connecting portion with installation department normal running fit makes the handle is in the rearmost, is difficult for the tong during the operation.
4. The hinge assembly uses the copper sleeve, the rotating medium is the copper sleeve, and the copper sleeve is low in cost and easy to replace.
