Description

Technical Field

[0001] This utility model relates to the field of brick clamp technology, and in particular to a brick clamp for building construction. Background Technology

[0002] A brick clamp is a tool used to move and hold bricks, commonly used on construction sites or in bricklaying operations. It is designed to help workers move bricks more easily and efficiently, reduce hand fatigue, and improve work efficiency. A brick clamp generally consists of clamping arms and a handle, and the brick is clamped by gripping the handle.

[0003] Existing brick clamps used in construction require workers to grip the handles tightly to hold and secure the bricks. However, prolonged brick handling can lead to hand fatigue, causing workers to loosen their grip due to hand pain or slippage. This results in the bricks falling to the ground and being damaged. Therefore, a new type of brick clamp is needed that can hold bricks without requiring prolonged gripping of the handles, thus avoiding the problems caused by workers' hand pain or slippage leading to bricks falling and being damaged. Utility Model Content

[0004] The purpose of this utility model is to provide a brick clamp for building construction in order to solve the above-mentioned problems.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A brick clamp for building construction includes a frame, a rotating shaft, and a rotating clamp. The frame is connected to the rotating clamp via the rotating shaft. A limiting component is installed on the frame, which includes a movable rod, a protrusion, a sleeve, and locking teeth. The movable rod passes through the interior of the rotating shaft, and the protrusion is fixedly connected to the side wall of the movable rod. A groove adapted to the protrusion is formed inside the rotating shaft. A sleeve is fixedly connected to one side of the frame, and locking teeth are fixedly connected to one end of the sleeve and the outer wall of the movable rod.

[0007] Preferably, a circular block is fixedly connected to one end of the movable rod, and the circular block is connected to the frame by a spring.

[0008] Preferably, both the bottom end of the frame and the bottom end of the rotating clamp are fixedly connected to limit protrusions.

[0009] Preferably, the movable rod and the rotating shaft are in clearance fit, and the movable rod and the rotating shaft can slide and rotate relative to each other.

[0010] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0011] In this application, the worker first presses the circular block to move the movable rod, causing the locking teeth on the movable rod to move away from the locking teeth on the sleeve. Then, the worker squeezes the handle on the rotating clamp, which works with the frame to clamp the brick. The worker then releases the circular block, and the spring pushes the circular block to move the movable rod. The locking teeth on the movable rod then engage with the locking teeth on the sleeve, limiting the rotation shaft. This way, even if the worker releases the handle, the rotating clamp will not rotate, thus avoiding the trouble of the worker's hand getting sore or slipping and releasing the handle, causing the brick to fall and be damaged.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-3 This utility model provides a technical solution:

[0019] Example 1:

[0020] like Figure 1-3As shown, a brick clamp for building construction includes a frame 1 and a rotating clamp 3 mounted on the frame 1 via a rotating shaft 2. The rotating clamp 3 is fixedly connected to the outer wall of the rotating shaft 2. A limiting component is installed on the frame 1, which includes a movable rod 4, a protrusion 5, a sleeve 6, and a locking tooth 7. The movable rod 4 passes through the interior of the rotating shaft 2, and the protrusion 5 is fixedly connected to the side wall of the movable rod 4. A groove adapted to the protrusion 5 is opened inside the rotating shaft 2. The number of protrusions 5 is set to two, and the two protrusions 5 are arranged in a mirror symmetrical arrangement with the movable rod 4 as the center. The sleeve 6 is fixedly connected to one side of the frame 1, and a locking tooth 7 is fixedly connected to one end of the sleeve 6 and the outer wall of the movable rod 4.

[0021] Example 2:

[0022] The technical solution is basically the same as that in Embodiment 1, except that, as Figure 2 As shown, a circular block 8 is fixedly connected to one end of the movable rod 4. The circular block 8 is connected to the frame 1 by a spring 9. The spring 9 abuts against one side of the circular block 8. Limiting protrusions are fixedly connected to the bottom end of the frame 1 and the bottom end of the rotating clamp 3. The limiting protrusions can improve the fixing effect on the bricks. The movable rod 4 and the rotating shaft 2 are clearance fit, and the movable rod 4 and the rotating shaft 2 can slide and rotate relative to each other.

[0023] Working Principle: In this embodiment, the brick clamp for construction uses a brick clamp. First, the worker presses the circular block 8, which moves the movable rod 4. The movable rod 4 then moves the locking teeth 7 away from the locking teeth on the sleeve 6, allowing the movable rod 4 to rotate freely. The worker can then press the handle on the rotating clamp 3 to make it rotate, clamping and fixing the brick. Simultaneously, the rotation of the rotating clamp 3 also drives the rotating shaft 2 to rotate, which in turn drives the movable rod 4 to rotate via the protrusion 5. Next, the worker releases the circular block 8, causing the spring 9 to push it to move. This moves the circular block 8, which in turn moves the movable rod 4. The movable rod 4 then engages the locking teeth 7 with the locking teeth 7 on the sleeve 6, limiting its rotation. The inability of the movable rod 4 to rotate prevents the rotating shaft 2 from rotating via the protrusion 5, thus limiting the rotation of the clamp 3. This prevents the brick from falling and being damaged due to worker hand pain or slipping when releasing the handle.

[0024] In summary, the worker first presses the circular block 8 to move the movable rod 4, causing the locking teeth 7 on the movable rod 4 to move away from the locking teeth 7 on the sleeve 6. Then, the worker squeezes the handle on the rotating clamp 3, which works with the frame 1 to clamp the brick. The worker then releases the circular block 8, and the spring 9 pushes the circular block 8 to move the movable rod 4. The locking teeth 7 on the movable rod 4 then engage with the locking teeth 7 on the sleeve 6, limiting the rotation shaft 2. This way, even if the worker releases the handle, the rotating clamp 3 will not rotate, thus avoiding the trouble of the worker's hand getting sore or slipping and releasing the handle, causing the brick to fall and be damaged.

[0025] The above description of the embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
