Quick assembly disassembly anchor clamps

Technical Field

The utility model relates to an anchor clamps technical field, specifically speaking relates to a quick assembly disassembly anchor clamps.

Background

The existing clamps comprise various types such as woodworking clamps, F-shaped clamps, G-shaped clamps and the like, and are used for clamping workpieces and modules in various shapes. The general fixture adopts a screw thread precession type design, and the screw rod is freely rotated to adjust the range to be clamped through an F-shaped or G-shaped fixture body and the screw rod with one end engaged and connected. However, the problem that the operation is very inconvenient and the working efficiency is low is that a user needs to manually rotate the screw rod continuously in the process of adjusting the caliber of the clamping opening, so that the screw rod moves forward or backward, and the distance between the two clamping parts is further adjusted. On the other hand, in the process of rotating the screw rod to reduce the distance of the clamping opening, after the clamped object is clamped, the clamping force is relatively small due to the limited torque, and the clamping force is difficult to be increased further.

When the wooden frame plate is assembled to build a concrete wall or a beam template, a large number of clamps are needed to clamp the wooden frames of two adjacent wooden frame plates to fix the wooden frame plates, and the clamps are needed to be quickly disassembled after concrete is solidified, so that the clamps can be repeatedly used. Therefore, the existing clamp for fixing through the rotary clamping of the screw rod not only has the problems of inconvenient operation, low working efficiency and relatively small clamping force, but also has the problems that the rotary movement of the screw rod in the clamping space is limited and the clamping force is not uniform when the clamp for the wood frame plate is fixed.

Of course, the sliding block 640 may be a pipe, a rod, or a block, and the sliding block 640 and the sliding hole 631 may be coupled by a sliding fit of a sliding rail and a sliding groove. Preferably, the slide hole 631 is a square hole, and the slide block 640 is a square tube or a square rod, so that the slide block 640 can be very simply limited to rotate in the slide hole 631. One end of the sliding block 640 is provided with a clamping head 641, and the other end is provided with a boss-shaped or detachably mounted stop head 644. The clamping head 641 is provided with a second clamping surface 642 opposite the first clamping surface 622. The two clamping surfaces are relatively parallel and in the same line of travel as the slide 640. As a preferable mode, the stopper 644 and the clamping head 641 can be used interchangeably, and both can be used as a boss of the blocking end part for blocking the sliding block 640 from falling off the sliding hole 631, and can also be used as an abutting part for clamping an intermediate object, respectively, the distance between the clamping head 641 and the sliding block 640 can be adjusted, and the distance between the end part of the clamping head 641 and the sliding block 640 can be adjusted in various modes, including adjustment of a chaste claw and a toothed structure, matching of a pin shaft and a pin shaft, matching of a screw rod and threads, and the like. The mounting arm 630 is provided with a first through hole 632 penetrating through the sliding hole 631, and the slider 640 is correspondingly provided with a second through hole 643 penetrating through the slider 640. When the clamp 600 is used, the first clamping surface 622 and the second clamping surface 642 abut against two sides of two matched bars 200 respectively, the first through hole 632 and the second through hole 643 are staggered relatively, the wedge 650 partially penetrates through the first through hole 632 and the second through hole 643, one part of the wedge 650 abuts against the mounting arm 630, the other part of the wedge 650 abuts against the sliding block 640, the staggered parts of the two through holes are reduced, and the sliding block 640 is pushed to move to clamp the two bars 200. The first and second through

holes

632 and 643 are long holes, the length direction of which is the slider movement direction, and the wedge 650 is a plate-like member. Of course, in some embodiments, the first and second through holes may be circular or elliptical holes, and the wedges may be respectively conical, conical or elliptical conical cylinders. The wedge 650 described herein is inclined with respect to the other side or non-parallel sides, has different widths, or has a tapered portion. When one end of the wedge 650 passes through the first and second staggered through

holes

632 and 643, the width of the wedge 650 entering the through holes is widened, and the distance of the through holes is reduced, so that the slider 640 is pushed to move. Therefore, the structure that the sliding block 640 can be pushed to move by changing the staggered distance of the two through holes through the through holes, no matter the specific shape, without departing from the concept of the present invention, the structure should be understood as the wedge 650.

In this embodiment, the wedge 650 is a right angle wedge structure, which includes two right angle sides and a hypotenuse side. The square edge at the upper end of the wedge 650 is the hammer end 651. When the clamp 600 is used for clamping two bars 200, the groove 201 can be arranged on the bar 200 at the position where the first clamping surface 622 and the second clamping surface 642 contact the bar 200, and the groove 201 enables the clamping table 621 and the clamping head 641 to be partially trapped in the groove, so that the sliding of the clamp 600 is reduced, the accurate positioning is ensured, and the clamping is firm.

In order to adapt to high-altitude operation or facilitate use, the wedge 650 and the clamp body 610 are connected through a flexible member, such as a rubber member, a rope chain, etc., an anti-falling structure is arranged on the wedge or the mounting arm, such as a tooth or a groove arranged on the sliding block, a pawl is correspondingly arranged on the mounting arm, or through holes are arranged at intervals on the wedge, and a pin shaft penetrates through the through holes on the lower side of the wedge to place the slip-off wedge.

As shown in fig. 22 to 25, the wood frame formwork 1 is applied to a beam formwork including a beam bottom formwork 14 and a beam side formwork 15 of a beam bottom. The side of the bars 200 at the periphery of the beam bottom formwork 14 is provided with a joint part 230, and the bottom bars 202 at the bottom of the beam side formwork 15, which are matched with the bars 200 of the beam bottom formwork 14, protrude out of the plate part 100 of the beam side formwork 15. The bottom bar 202 is provided with a mating portion 240 on the front side facing the plate member 100. The beam bottom template 14 and the beam side template 15 are spliced in a matched mode, and the split joint is quick and small. Further, the lower ends of the bottom bars 202 are located at the same level as the lower ends of the beam bottom forms 14, so that the beam bottom forms 14 and the bottom bars 202 can be supported at the same time in the support structure of the beam bottom forms, and the support structure can be simplified.

The present invention and its embodiments have been described above schematically, and the description is not limited thereto, and what is shown in the drawings is only one of the embodiments of the present invention, and the actual structure is not limited thereto. Therefore, if the person skilled in the art receives the teaching of the present invention, without departing from the inventive spirit of the present invention, the person skilled in the art should also design the similar structural modes and embodiments without creativity to the technical solution, and all shall fall within the protection scope of the present invention.
