Description

Labor-saving brick card

technical field

The utility model relates to the technical field of construction tools, in particular to a labor-saving brick.

Background technique

In the production of bricks and construction projects, the workload of loading and unloading bricks is large. In the process of loading and unloading, the operator has to use a lot of grip force (to generate pressure, so that the friction force is equal to gravity) for the ordinary brick card in addition to the gravity of the brick. Keeping the same hand-holding posture for a long time is easy to fatigue, labor-intensive, and inefficient.

Contents of the invention

The technical problem to be solved by the utility model is to provide a labor-saving brick card, which can solve the problem of high labor intensity and laboriousness, realize labor-saving and flexible grip of loading and unloading bricks, simple operation and strong practicability.

In order to solve the above-mentioned technical problems, the technical solution adopted by the utility model is: a labor-saving brick, including a left-hand piece composed of a left handle and a left gripper, the left-hand piece and the right-hand piece are connected by a bolt, and the left-hand piece is provided with a Vertical straight teeth, the right hand part is provided with a groove body matching with the vertical straight teeth, and the groove body is respectively provided with a gear rod installation hole, a work piece installation hole and a spring fixing hole along the direction towards the right gripper. The part is composed of a rotating block and an inserting rod inserted into the rotating block. A spring mounting hole is opened on the rotating rod of the rotating block. The gear rod is inserted into the mounting hole of the gear rod and matched with the rotating rod. Cooperate, one end of the spring is fixed in the spring fixing hole, and the other end of the spring is fixed in the spring installation hole.

The rotating rod is composed of a collar and a triangular rotating rod fixedly connected with the collar.

The spring fixing hole is a non-through hole opened on the edge of the tank body.

A plurality of bald nails are evenly arranged on the plane where the left gripper and the right gripper are in contact with the brick body.

The inserting rod is composed of a first rod body inserted into the rotating block and a second rod body inserted into the groove body.

The latch is secured by a retaining pin.

The labor-saving brick card provided by the utility model generates downward elastic force through the rotating spring to make the work piece generate downward force; after blocking the rotating rod of the work piece with the gear lever, the operator grabs the left and right handles until it passes through one of the handles The brick body can be lifted, which can solve the problem of high labor intensity and effort, realize labor-saving and flexible grip of loading and unloading bricks, simple operation and strong practicability; the design of the bald nail further increases the friction force and ensures the labor-saving effect.

Detailed ways

As shown in Figures 1-6, a labor-saving brick card includes a left-handed piece consisting of a left handle 2 and a left grip 11. It is characterized in that: the left-handed piece and the right-handed piece are pinned through a latch 9, and the left-handed piece is provided with Vertical straight teeth 7, the right hand piece is provided with a groove body 12 matched with the vertical straight teeth 7, and the groove body 12 is respectively opened with a gear rod installation hole 12-1, a working piece along the direction toward the right gripper 1 Mounting hole 12-2 and spring fixing hole 12-3, work piece 5 is made up of rotating block 5-1 and inserting rod 4 that inserts rotating block 5-1, offers on the rotating rod 5-1-1 of rotating block 5-1 Spring installation hole 5-1-2 is arranged, and gear lever 6 is inserted into gear lever installation hole 12-1 and cooperates with rotary rod 5-1-1, and the bar head of rotary rod 5-1-1 is matched with vertical spur tooth 7 Cooperate, one end of the spring 3 is fixed in the spring fixing hole 12-3, and the other end of the spring 3 is fixed in the spring installation hole 5-1-2.

The rotating rod 5-1-1 is made up of a collar and a triangular rotating rod 5-1 fixedly connected with the collar.

The spring fixing hole 12 - 3 is a non-through hole opened on the edge of the tank body 12 .

A plurality of bare nails 13 are evenly arranged on the plane where the left gripper 11 and the right gripper 1 are in contact with the brick body.

The insertion rod 4 is composed of a first rod body 4-1 inserted into the rotating block 5-1 and a second rod body 4-2 inserted into the groove body 12.

The bolt 9 is fixed by a fixing pin 10 .

The right hand piece is made up of right gripper 1 and right handle 8.

The working process of the present utility model is as follows:

After rotating the spring 3 for two weeks, fix one end of the spring 3 in the spring mounting hole 5-1-2, and fix the other end in the spring fixing hole 12-3, so that the work piece 5 generates a downward force, and the working piece 6 is used to move the work piece. The rotating rod 5-1-1 of part 5 blocks, and the triangular rotating rod 5-1 snaps into the position between the two racks at the top of the vertical straight teeth 7, as shown in Figure 7.

When in use, the user uses the left gripper 11 and the right gripper 1 to clamp the brick body (the design value is based on four bricks). When the left gripper 11 and the right gripper 1 clamp the brick body, the user grasps Hold the left handle 2 and the right handle 8, so that the vertical straight teeth 7 move upwards, and the rotary rod 5-1-1 snaps into the position between the next two racks of the vertical straight teeth 7 until the user can pass one of them The brick body can be lifted by the handle.

When the user needs to put down the brick body, press the rotary block 5-1 inwardly to make the rotary rod 5-1-1 break away from the position between the two racks of the vertical straight teeth 7, and the left gripper 11 and the right gripper 1 Open, you can put down the brick body.
