Detailed Description

The technical solutions in the embodiments of the present invention are described below clearly and completely, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts all belong to the protection scope of the present invention.

As shown in figures 1 to 5, a chip placing tool for manufacturing concrete test blocks comprises a sucker 1, a connecting rod 2 and a movable rod 3, wherein the sucker 1 is communicated with a control valve 4, the connecting rod 2 is fixedly connected with the sucker 1, the movable rod 3 is slidably connected with the connecting rod 2, the control valve 4 can be opened through the sliding of the movable rod 3, and the sucker 1 is communicated with the atmosphere.

When the chip sucking device is used, the sucking disc 1 is placed above the chip by the aid of the handheld connecting rod 2 and then pressed downwards, so that air between the sucking disc 1 and the chip is exhausted, and the chip is sucked. Then, the chip was transferred to the top of the concrete block, and pressed downward to press the chip into the concrete block. Finally, the control valve 4 is opened through the movable rod 3, so that air enters between the suction cup 1 and the chip, and the suction cup 1 is separated from the chip.

Through the operation, the contact between the hand and the concrete can be avoided, and the defect on the surface of the concrete is prevented. After the operation is finished, the surface of the chip needs to be pressed by fingers, so that the upper surface of the chip is flush with the upper surface of the concrete test block.

Further, the connecting rod 2 is a hollow rod, and the movable rod 3 is positioned in the connecting rod 2; the lower end of the connecting rod 2 is communicated with the sucker 1, and the control valve 4 is fixed in the hollow rod. Of course, the movable bar 3 may be located outside the connecting bar 2, but when located inside, the integrity is good and damage of the movable bar 3 can be avoided. The setting of movable rod 3 can realize sliding connection in connecting rod 2, and when the rod footpath of movable rod 3 was thinner, in order to avoid both to connect the back and produce and rock, can set up necking down structure or be fixed with the annular plate in connecting rod 2 in order to reduce its internal diameter.

Further, a return spring 5 is arranged between the connecting rod 2 and the movable rod 3, when the movable rod 3 is pressed downwards to open the control valve 4, the return spring 5 is compressed to generate elastic potential energy, and after the external force is cancelled, the return spring 5 releases the elastic potential energy to reset the movable rod 3, and the control valve 4 is closed.

Further, a return spring 5 is arranged in the connecting rod 2, and two ends of the return spring 5 are respectively abutted against the connecting rod 2 and the movable rod 3; specifically, the method comprises the following steps: a circle of corresponding bulges are arranged inside the connecting rod 2 and outside the movable rod 3 and are propped against the reset spring 5.

Further, in order to facilitate pressing, a pressing plate 6 is fixed at the upper end of the movable rod 3; the lower end of the movable rod 3 is conical and can be better contacted with a valve core 12 in the control valve 4.

Further, in order to improve the anti-skid performance, a handle sleeve 7 is sleeved outside the connecting rod 2, and the handle sleeve 7 can be a rubber handle sleeve 7.

Further, although the above structure can realize the placement of the chip, it is still inconvenient because the chip is usually pressed again after the placement.

Therefore, the push plate 8 is further arranged, the push plate 8 is fixedly connected with the movable rod 3 through the support rod 9, and two ends of the support rod 9 are fixedly connected with the push plate 8 and the movable rod 3 respectively.
