Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a device for fixing cement nails on building walls. Background Art

[0002] Cement nails are special nails used to fix components or decorative materials on hard walls such as concrete and bricks. They are usually made of metal, with a sharp nail body and a flat head. They usually have threads or rough surfaces to better embed into the wall when fixed, providing a more secure fixing effect. Building walls usually need to fix and install various components or decorative materials to ensure that they are firmly connected to the wall, so cement nails are needed for fixing.

[0003] The existing fixing method is usually to hold the nails directly by hand and then hammer them with a hammer to drive the nails into the wall. However, this method will cause the cement nails to slip due to unstable holding, resulting in deviation in the angle of nailing. The nails cannot be nailed into the wall vertically, making the object unreliable. In addition, this method is dangerous and can easily cause hand injuries to workers, resulting in reduced work efficiency. In view of the above problems, a person skilled in the art has proposed a device for fixing cement nails on building walls to solve the above problems. Utility Model Content

[0004] In order to remedy the above shortcomings, the utility model provides a device for fixing cement nails on building walls, aiming to improve the problem in the prior art that cement nails are usually fixed by hand, which makes the nails easy to slide and the angle of nailing deviates, thereby resulting in unreliable fixation of objects.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a device for fixing cement nails on building walls, comprising a mounting shell, a handle fixedly connected to the outside of the mounting shell, a motor installed inside the handle near the connection with the mounting shell, a threaded rod fixedly connected to the output end of the motor, a threaded sleeve threadedly connected to the outside of the threaded rod, connecting rods rotatably connected to both ends of the threaded sleeve, a guide rod fixedly connected to the inside of the mounting shell, two sliders slidably connected to the outside of the guide rod, a splint fixedly connected to the outside of the slider, a protective assembly fixedly connected to the top side of the mounting shell, and a positioning assembly provided on the bottom side of the mounting shell.

[0006] Furthermore, the positioning assembly includes a fixed plate, which is fixedly connected to the right bottom of the mounting shell. A cross-shaped groove is provided inside the fixed plate. Four telescopic rods are fixedly connected to the inner side of the cross-shaped groove. A clamping block is fixedly connected to the other end of the telescopic rod. A spring is provided on the outer side of the telescopic rod.

[0007] Furthermore, the protective component includes a sleeve, the outer side of the sleeve is fixedly connected to the outer side of the mounting shell, the interior of the sleeve is slidably connected to a sliding rod, the top end of the sliding rod is fixedly connected to a fixing block, and the bottom end of the sliding rod is fixedly connected to a pressure block.

[0008] Furthermore, the other ends of the two connecting rods are respectively rotatably connected to the outside of the two sliding blocks, and the two sliding blocks are symmetrically arranged.

[0009] Furthermore, the opposing surfaces of the two clamps are provided with anti-slip grooves, and the shape of the clamp is set to be L-shaped.

[0010] Furthermore, a button is provided at one end of the handle close to the top, and the button is electrically connected to the motor.

[0011] Furthermore, one end of the spring is fixedly connected to the inner side of the cross-shaped groove, and the other end of the spring is fixedly connected to the outer side of the clamping block.

[0012] Furthermore, the outside of the pressure block is slidably connected to the inner wall of the sleeve, and a magnet is arranged inside the pressure block.

[0013] The utility model has the following beneficial effects:

[0014] 1. In the utility model, the threaded rod is driven to rotate by a motor, so that the threaded sleeve drives the connecting rods at both ends to move. The connecting rod pulls the slider to move, which can drive the two clamps to approach each other, thereby clamping and fixing the cement nails. When workers drive the cement nails into the wall, the nails will not move, ensuring the angle of the nails, thereby making the connection between objects more secure.

[0015] 2. In the utility model, the clamping block is pushed toward the center of the fixing plate by the spring, so as to pre-fix the cement nail, ensuring that the angle will not change when the nail is driven into the wall. The sleeve is used to cover the cement nail, and when the hammer hits the fixing block, the cement nail is driven into the wall through the pressure block. When the cement nail breaks, it will not injure the worker, thus achieving a good protective effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Reference Figure 1-Figure 2 The utility model provides an embodiment: a device for fixing cement nails on a building wall, comprising a mounting shell 1, a handle 2 is fixedly connected to the outside of the mounting shell 1, a motor 3 is installed inside the handle 2 near the connection with the mounting shell 1, a threaded rod 4 is fixedly connected to the output end of the motor 3, a threaded sleeve 5 is threadedly connected to the outside of the threaded rod 4, and connecting rods 6 are rotatably connected at both ends of the threaded sleeve 5, a guide rod 9 is fixedly connected to the inside of the mounting shell 1, two sliders 7 are slidably connected to the outside of the guide rod 9, and a clamping plate 8 is fixedly connected to the outside of the slider 7, a protective component is fixedly connected to one side of the top of the mounting shell 1, a positioning component is arranged on one side of the bottom of the mounting shell 1, the other ends of the two connecting rods 6 are respectively rotatably connected to the outside of the two sliders 7, the two sliders 7 are symmetrically arranged, and the opposite surfaces of the two clamping plates 8 are arranged with anti-slip grooves, and the shape of the clamping plate 8 is arranged in an L-shape, and a button 18 is arranged at one end of the handle 2 near the top, and the button 18 is electrically connected to the motor 3.

[0024] Specifically, the handle 2 is connected to the mounting shell 1, which makes it convenient for workers to hold the entire device for movement, thereby facilitating the nailing of cement nails into the wall, improving work efficiency, and the motor 3 can be controlled by the button 18. Starting the motor 3 can drive the threaded rod 4 to rotate, thereby causing the threaded sleeve 5 to move, and the threaded sleeve 5 will drive the connecting rod 6 connected at both ends to move, and the slider 7 is pulled by the connecting rod 6 to slide along the guide rod 9. The guide rod 9 can limit the moving direction of the slider 7, so that the slider 7 maintains horizontal movement, and drives the clamping plates 8 connected thereto to approach each other, so as to achieve the clamping and fixing of the cement nail, so that when the worker nails the cement nail into the wall, the nail will not move, ensuring the nailing angle, making the connection between objects more firm, and ensuring that the worker's hands will not be injured, thereby improving the safety of construction, wherein the anti-slip grooves arranged on the opposite surfaces of the two clamping plates 8 can prevent the cement nail from sliding after clamping, ensuring the effect when nailing into the wall, and the shape of the clamping plate 8 is set to be L-shaped, which can ensure the structural strength of the clamping plate 8 and make it more firm when clamping.

[0025] Reference Figure 2 and Figure 4 The positioning assembly includes a fixed plate 14, which is fixedly connected to the right bottom of the mounting shell 1. A cross-shaped groove is opened inside the fixed plate 14, and four telescopic rods 15 are fixedly connected to the inner side of the cross-shaped groove. The other end of the telescopic rod 15 is fixedly connected to a clamping block 16. A spring 17 is sleeved on the outer side of the telescopic rod 15, and one end of the spring 17 is fixedly connected to the inner side of the cross-shaped groove, and the other end of the spring 17 is fixedly connected to the outer side of the clamping block 16.

[0026] Specifically, the fixing plate 14 is connected to the outside of the mounting shell 1 so that the fixing plate 14 remains stable, and then the four telescopic rods 15 fixed in the cross-shaped groove opened inside can make the four clamping blocks 16 close together. At the same time, a small hole is left in the center of the clamping block 16 to facilitate the insertion of the concrete nail. After the concrete nail is inserted, the telescopic rod 15 will be pressed to shrink, thereby shrinking the spring 17, and the spring 17 will apply a reaction force to the clamping block 16, thereby clamping the concrete nail, which has an auxiliary fixing effect. When the concrete nail is nailed into the wall, it will not slide and can enter the wall vertically, ensuring a firm connection between the object and the wall.

[0027] Reference Figure 1 and Figure 3 The protective component includes a sleeve 10, the outer side of the sleeve 10 is fixedly connected to the outer side of the mounting shell 1, the interior of the sleeve 10 is slidably connected with a slide rod 12, the top end of the slide rod 12 is fixedly connected with a fixed block 11, the bottom end of the slide rod 12 is fixedly connected with a pressure block 13, the outer side of the pressure block 13 is slidably connected to the inner wall of the sleeve 10, and the interior of the pressure block 13 is provided with a magnet.

[0028] Specifically, the sleeve 10 can play a protective role when the cement nail is driven into the wall, so that when the cement nail is bent, it will not burst onto the worker and cause harm, thereby ensuring the safety of the construction. By hitting the fixed block 11, pressure can be applied to the sliding rod 12 and transmitted to the pressure block 13, thereby impacting the cement nail so that the cement nail is driven into the wall. The magnet arranged inside the pressure block 13 can adsorb the cement nail, making it difficult for the cement nail to fall off, thereby facilitating clamping.

[0029] Working principle: When using this device, first put the cement nail into the center of several clamping blocks 16, which will cause the clamping blocks 16 to pressurize the telescopic rod 15, causing the telescopic rod 15 to shrink. At the same time, the spring 17 shrinks and applies a reaction force to the clamping block 16 to clamp the cement nail, thereby pre-fixing the cement nail. Then press the button 18 to start the motor 3, and the motor 3 drives the threaded rod 4 to rotate, thereby causing the threaded sleeve 5 to move, thereby driving the connecting rods 6 at both ends to move, so that the slider 7 can slide along the guide rod 9 and drive the clamping plates 8 to approach each other, thereby clamping and fixing the cement nail. When the worker nails the cement nail into the wall, the nail will not move, ensuring the angle of nailing, making the connection between objects more secure, and ensuring that the worker's hands will not be injured, thereby improving the safety of construction. When a hammer is used to hit the concrete nail, the upper part of the nail will be inside the sleeve 10. The hammer hits the fixed block 11, so that the force is transmitted to the pressure block 13 through the slide rod 12, thereby applying pressure to the concrete nail, thereby driving the concrete nail into the wall. The sleeve 10 can prevent the concrete nail from bursting when it is bent, causing harm to the workers, thereby reducing work efficiency.
