Abstract
Description
Technical Field
[0001] The present application relates to the technical field of anti-tilt of coil nail guns, and more specifically, to an anti-tilt nozzle of a coil nail gun. Background Art
[0002] The anti-tilt nozzle of a coil nail gun is a crucial component. It primarily prevents the nail from tilting during driving. Without an anti-tilt nozzle, nails can be driven crookedly due to various factors (such as operating angle or uneven surfaces), impacting work quality. The anti-tilt nozzle corrects the direction of nail driving, ensuring it enters the object as vertically as possible. This is crucial in applications requiring precise nailing, such as carpentry and construction.
[0003] During the operation of a traditional coil nail gun, the nail output tube of the coil nail gun often relies on simple mechanical contact when in contact with the object to be nailed due to the lack of effective anti-slip and fit stabilization measures. The friction between the nail output tube and the surface of the object is limited. As a result, during the nailing operation, the nail output tube is easily affected by the reaction force of nailing, operator hand shaking or uneven surface of the object, causing it to slip or slightly tilt, making it impossible for the nail to be accurately driven into the object at the predetermined position and angle, seriously reducing the nailing accuracy.
[0004] On the other hand, when the coil nail gun's output tube is tilted by external forces, traditional coil nail guns lack the reliable restoring force to ensure the tube returns to a vertical position. Once the output tube tilts, it is almost unavoidable during nailing, affecting nailing accuracy, reducing work efficiency and product quality, and increasing production costs and the burden of subsequent repair work.
[0005] In view of this, the present application proposes an anti-tilt nozzle of a coil nail gun. Utility Model Content

[0015] 1. This application places the negative pressure plate close to the object to be nailed, and the negative pressure plate fits precisely with the surface of the object to prevent air leakage, so that a small air pump can smoothly extract the air inside the negative pressure plate, generating negative pressure adsorption force, further enhancing the fit stability of the extension tube and the surface of the object, improving the nailing accuracy, and effectively preventing it from sliding or tilting during the nailing process, thereby greatly improving the nailing accuracy of the extension tube.
[0016] 2.

[0021] The present application is further described in detail below with reference to the accompanying drawings.
[0022] Reference Figure 1-Figure 3 The embodiment of the present application provides an anti-tilt nozzle of a coil nail gun, comprising a fixed cylinder 1, an extension tube 2 movably inserted at the lower part of the interior of the fixed cylinder 1; a spherical groove 3 is opened at the lower part of the inner wall of the fixed cylinder 1, and a spherical sleeve 4 is fixedly connected to the upper part of the outer wall of the extension tube 2, and the spherical sleeve 4 is located inside the spherical groove 3. When the nail output tube is tilted by external force, the spherical sleeve 4 flips in the spherical groove 3, so that the extension tube 2 can flexibly adjust the angle within a certain range to adapt to the tilt change of the nail output tube, and it is easy to restore to a perpendicular state to the surface of the object in the later stage, effectively preventing the nail from tilting.
[0023] The lower end of the extension tube 2 is fixedly sleeved with a fixed sleeve 6, and a negative pressure plate 5 is fixedly connected to the upper outer wall of the fixed sleeve 6. The outer wall of the extension tube 2 is fixedly connected with a small air pump 8, and the lower end of the small air pump 8 is fixedly inserted with an exhaust pipe 9, and the lower end of the exhaust pipe 9 extends into the interior of the negative pressure plate 5. The negative pressure plate 5 is tightly attached to the nailing object and can fit precisely with the surface of the object to prevent air leakage, so that the small air pump 8 can smoothly extract the air inside the negative pressure plate 5, generate negative pressure adsorption force, further enhance the fitting stability of the extension tube 2 and the surface of the object, and improve the nailing accuracy.
[0024] Reference Figure 1 and Figure 2 The lower end surfaces of the negative pressure plate 5 and the fixed sleeve 6 are fixedly connected with a silicone ring 7. The silicone ring 7 is close to the nailing object and can play a good anti-slip role, effectively preventing the extension tube 2 from sliding due to insufficient friction with the surface of the object during nailing. The outer wall of the silicone ring 7 is fixedly connected with a lifting block 11, which makes it convenient for the staff to uncover the negative pressure plate 5.
[0025] Reference Figure 1The upper end of the small air pump 8 is fixedly connected with an air outlet pipe 10. The small air pump 8 draws out the air in the negative pressure plate 5 through the exhaust pipe 9 and discharges it through the air outlet pipe 10, providing power support for the negative pressure adsorption force generated between the negative pressure plate 5 and the surface of the object, so that the extension tube 2 can better fit the surface of the object, effectively preventing it from sliding or tilting during the nailing process, and greatly improving the nailing accuracy of the extension tube 2.
[0026] Reference Figure 1 and Figure 2 The upper end of the fixed cylinder 1 is fixedly connected with a sealing ring 12, and both sides of the upper end surface of the fixed cylinder 1 are fixedly connected with limiting plates 13. The sealing ring 12 plays a sealing role, which helps to maintain the internal air pressure of the device stable and facilitates the subsequent related components to function.
[0027] Reference Figure 1 and Figure 2 The end surfaces of the two limiting pieces 13 that are away from each other are fixedly connected to a threaded barrel 14, and the threaded barrel 14 is communicated with the limiting piece 13. The interior of the threaded barrel 14 is connected to a knob 15 by a threaded rotation, and the end surfaces of the two knobs 15 that are close to each other are rotatably connected to an extrusion piece 16. By clamping the two limiting pieces 13 onto the nail output tube of the coil nail gun and rotating the knob 15 to drive the extrusion piece 16 to clamp the nail output tube, the anti-tilt gun nozzle device can be firmly installed on the nail output tube of the coil nail gun, ensuring the stability of the connection between the device and the coil nail gun during the nailing process, and avoiding affecting the anti-tilt function due to a loose connection.
[0028] Reference Figure 2 and Figure 3 , a fixing ring 17 is fixedly connected to the upper part of the inner wall of the fixing cylinder 1, and a plurality of mounting holes 18 are provided on the end faces of the fixing ring 17 and the extension tube 2 close to each other. A soft rubber column 19 is fixedly connected between the two mounting holes 18, and a buffer spring 20 is provided on the outer periphery of the soft rubber column 19, and the two ends of the buffer spring 20 are respectively fixedly connected to the two mounting holes 18. The soft rubber column 19 and the buffer spring 20 both have good elasticity. The soft rubber column 19 plays a buffering role, which can effectively reduce the influence of external impact force on the buffer spring 20, so that the buffer spring 20 is not easy to shake. The two together provide good restoring force. When the nail tube is tilted, the extension tube 2 and the fixed cylinder 1 can be restored to a vertical state with the surface of the object, thereby ensuring the accuracy and stability of nailing and preventing the occurrence of nailing tilt.
[0029] Working principle: When in use, the staff first clamps the two limiting plates 13 on the fixed tube 1 onto the nail output tube of the coil nail gun, and the top of the nail output tube presses against the sealing ring 12 on the fixed tube 1, and then turns the knob 15 on the threaded tube 14. The rotation of the knob 15 drives the extrusion plate 16 to move until the two extrusion plates 16 clamp the nail output tube.
[0030] When nailing is required, the silicone ring 7 on the negative pressure plate 5 is placed tightly against the object to be nailed. The silicone ring 7 not only prevents slipping but also precisely adheres to the surface of the object to prevent air leakage. First, the small air pump 8 is activated. The small air pump 8 extracts the air inside the negative pressure plate 5 through the exhaust pipe 9. The air in the negative pressure plate 5 is then discharged through the outlet pipe 10 on the small air pump 8. A negative pressure adsorption force is generated between the negative pressure plate 5 and the surface of the object, allowing the extension tube 2 to better adhere to the surface of the object, preventing the extension tube 2 from slipping or tilting during nailing, and improving the nailing accuracy of the extension tube 2.
[0031] After the negative pressure plate 5 is firmly adsorbed, when the nail-out tube is tilted by external force, the spherical sleeve 4 on the extension tube 2 flips in the spherical groove 3 on the inner wall of the fixed tube 1, and at the same time, the multiple soft rubber columns 19 and buffer springs 20 between the extension tube 2 and the fixed ring 17 will produce corresponding deformations. The soft rubber columns 19 and the buffer springs 20 both have good elasticity, and the soft rubber columns 19 play a buffering role, making it difficult for the buffer spring 20 to shake, so that the soft rubber columns 19 and the buffer springs 20 provide a restoring force, and the buffer springs 20 and the soft rubber columns 19 return to their original state, so that the extension tube 2 and the fixed tube 1 remain perpendicular to the surface of the object, thereby preventing the nailing from tilting; after nailing is completed, pull the lifting block 11 on the silicone ring 7 to allow air to quickly enter the negative pressure plate 5, and the negative pressure plate 5 can be separated from the surface of the object.
[0032] The above are only preferred specific implementation methods of the present invention, but the protection scope of the present invention is not limited to them. Any technician familiar with the technical field can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention within the technical scope disclosed by the present invention, and they should be covered by the protection scope of the present invention.
