Description

Technical Field

[0001] The present application relates to the technical field of fasteners, and more specifically, to a high-reliability double-line fine-pitch drywall screw. Background Art

[0002] The double-thread fine-pitch drywall screws in drywall screws have double threads, the threads are finer, and the pitch between the two threads is the same. This type of nail is usually used to fix dry gypsum boards and other non-load-bearing interior wall materials.

[0003] In the related art, according to the patent compared thereto, a through groove is proposed to penetrate the thread on the nail tip, so that the thread on the nail tip is divided into segments, which will increase the resistance to the rotation of the thread during the drilling process of the screw and reduce the work efficiency. For example, the patent with the prior art announcement number CN213176377U provides a high-hardness double-line fine-pitch drywall screw. When using the double-line fine-pitch drywall screw, the device contacts the nail tip of the nail tip with the surface of the fixed object, rotates the screw, and makes the nail tip drill a positioning hole on the surface of the fixed object. When the screw is screwed into the inside of the fixed object, the nail tip groove can reduce the contact area between the nail tip and the fixed object. The thread is located below the nail tip groove, and the continuous double-line fine-pitch thread is easier to tap the thread inside the fixed object, so that the screw is connected to the fixed object, thereby improving the work efficiency of using the screw.

[0004] Although the above-mentioned prior art solution can improve the drilling efficiency and thus improve the work efficiency by setting the nail tip groove, it still has the following defects: when drilling, the nail tip can contact the object from any direction, causing the screw to drill an inclined hole, which may damage the object and reduce the strength of the screw when fixing.

[0005] In view of this, we propose a high-reliability double-line fine-pitch drywall screw. Utility Model Content

[0006] The utility model provides a high-reliability double-line fine-thread dry wall screw, which solves the problem that when drilling, the nail tip can contact an object from any direction, causing the screw to drill an inclined hole, which in turn damages the object and reduces the strength of the screw when fixing.

[0007] To solve the above problems, the embodiment of the present application provides a high-reliability double-line fine-pitch drywall screw, including a drywall screw body;

[0008] A check assembly, wherein the check assembly is arranged outside the bottom end of the nail head, and four check assemblies are arranged, and the check assembly is used to assist in fixing the drywall nail body;

[0009] A nail tip assembly is arranged at one end of the drywall screw body, and is used for positioning and straightening the drywall screw body.

[0010] Furthermore, the nail head is fixedly arranged at the other end of the drywall screw body, four exhaust holes are opened at the top of the nail head, chip removal grooves are symmetrically opened on the outer side of the drywall screw body, and a first double-line fine pitch thread is arranged on the outer side of the drywall screw body.

[0011] Furthermore, a cross notch is provided at the top of the nail head, and four matching grooves are provided on the outer side of the bottom end of the nail head. The arrangement of the matching grooves facilitates the use of the non-return assembly.

[0012] Furthermore, the non-return assembly includes a resilient member, which is fixedly arranged on the inner side of the matching groove, and a non-return claw is fixedly arranged on the bottom end of the resilient member, and the non-return claw is rotatably arranged on the inner side of the matching groove, and a non-return tooth is arranged on the bottom end of the non-return claw. The non-return assembly can provide a reverse supporting force for the drywall screw body, thereby preventing the drywall screw body from withdrawing from the fixed hole due to external factors, such as vibration, thereby improving the reliability of the drywall screw body when in use.

[0013] Furthermore, the two sides of the resilient component do not contact the matching groove, and the resilient component is made of elastic metal material. When the drywall screw body is taken out, the anti-return claw will return to its original position due to the elastic force of the resilient component.

[0014] Furthermore, the nail tip assembly includes a nail tip body, the nail tip body is conically arranged, a nail tip end is arranged at one end of the nail tip body, a positioning claw is symmetrically fixedly arranged on the outer side of the nail tip end, a positioning tip is arranged at the bottom end of the positioning claw, and the nail tip end and the positioning tip are arranged at the same level, so the positioning tip and the nail tip tip contact the object at the same time, preventing the nail tip tip from tilting and drilling into the interior of the object, thereby improving its usage strength.

[0015] Furthermore, a spiral groove is provided on the outer side of the nail tip body, and the nail tip body is fixedly arranged at one end of the drywall nail body. A second double-line fine thread is provided on the outer side of the nail tip body. The spiral groove is used to discharge debris, and the second double-line fine thread facilitates drilling a hole and entering at the positioning point.

[0016] One or more technical solutions provided in the embodiments of the present application have at least the following technical effects or advantages:

[0017] 1. The present application sets a nail tip assembly, wherein the nail tip and the positioning tip in the nail tip assembly are set at the same level, so that the positioning tip and the nail tip contact the object at the same time, preventing the nail tip from tilting and drilling into the object, thereby improving its use strength;

[0018] 2. The present application provides a non-return assembly. After the drywall screw body is fixed, the non-return assembly can provide a reverse holding force for the drywall screw body, thereby preventing the drywall screw body from withdrawing from the fixed hole due to external factors such as vibration, thereby improving the reliability of the drywall screw body when in use.

[0024] The present application is further described in detail below in conjunction with the accompanying drawings.

[0025] Reference Figure 1 and Figure 2 , a high-reliability double-line fine-thread drywall screw, comprising a drywall screw body 1;

[0026] The non-return assembly 2 is arranged outside the bottom end of the nail head 101. Four non-return assemblies 2 are arranged. The non-return assemblies 2 are used to assist in fixing the drywall nail body 1.

[0027] The nail tip assembly 3 is arranged at one end of the drywall screw body 1 , and the nail tip assembly 3 is used to position and straighten the drywall screw body 1 .

[0028] The nail tip 302 and the positioning tip 306 in the nail tip assembly 3 are arranged at the same level, so the positioning tip 306 and the nail tip 302 contact the object at the same time, preventing the nail tip 302 from tilting and drilling into the object, thereby improving its use strength. After the drywall screw body 1 is fixed, the non-return assembly 2 can provide a reverse supporting force for the drywall screw body 1, thereby preventing the drywall screw body 1 from withdrawing from the fixed hole due to external factors, such as vibration, thereby improving the reliability of the drywall screw body 1 when in use.

[0029] Reference Figure 1 , Figure 2 and Figure 3 The nail head 101 is fixedly arranged at the other end of the drywall screw body 1, four exhaust holes 103 are opened at the top of the nail head 101, and chip grooves 105 are symmetrically opened on the outside of the drywall screw body 1. The outside of the drywall screw body 1 is provided with a first double-line fine thread 104, a cross notch 102 is opened at the top of the nail head 101, and four matching grooves 1011 are opened on the outside of the bottom end of the nail head 101.

[0030] When the nail head 101 is close to an object, there will be more air between the nail head 101 and the object. The air will be discharged from the exhaust hole 103, and the debris can be discharged from the chip groove 105 and the exhaust hole 103, thereby reducing the resistance of the drywall nail body 1 when in use.

[0031] Reference Figure 1 and Figure 2 The non-return assembly 2 includes a rebound component 201, which is fixedly arranged on the inner side of the matching groove 1011. A non-return claw 202 is fixedly arranged on the bottom end of the rebound component 201. The non-return claw 202 is rotatably arranged on the inner side of the matching groove 1011. Non-return teeth 203 are arranged on the bottom ends of the non-return claws 202. Both sides of the rebound component 201 are not in contact with the matching groove 1011. The rebound component 201 is made of elastic metal material.

[0032] As the drywall screw body 1 rotates, the non-return teeth 203 in the non-return assembly 2 will slowly contact the object, and the angle between the non-return claw 202 and the drywall screw body 1 will gradually increase, and the resilient member 201 will be deformed, while providing an elastic force for the non-return claw 202. Due to the setting of the non-return teeth 203, the elastic force will make the non-return teeth 203 tightly grasp the object, achieving a non-return effect, and preventing the drywall screw body 1 from exiting the hole due to external vibration.

[0033] Reference Figure 1 and Figure 4The nail tip assembly 3 includes a nail tip body 301, which is conically arranged. A nail tip 302 is arranged at one end of the nail tip body 301, and a positioning claw 305 is symmetrically fixedly arranged on the outer side of the nail tip 302. A positioning tip 306 is arranged at the bottom end of the positioning claw 305. A spiral groove 304 is opened on the outer side of the nail tip body 301. The nail tip body 301 is fixedly arranged at one end of the drywall screw body 1, and a second double-line fine pitch thread 303 is arranged on the outer side of the nail tip body 301.

[0034] When the drywall screw body 1 is used, the nail tip 302 and the positioning tip 306 first contact the object to prevent the nail tip body 301 from tilting. The nail tip body 301 is straightened through multiple positioning points to prevent the drywall screw body 1 from tilting when fixed, thereby improving the strength during use. The drilled wood chips are discharged to the outside through the spiral groove 304 to prevent excessive accumulation in the hole.

[0035] Working principle: When using the drywall screw body 1, insert the cross cutter into the cross notch 102, and then rotate the nail head 101 so that the drywall screw body 1 drives the nail tip assembly 3 to rotate and drill a hole at the positioning position, and enter the drilled hole. The nail tip 302 and the positioning tip 306 first contact the object, thereby preventing the nail tip body 301 from tilting. The nail tip body 301 is straightened through multiple positioning points to prevent the drywall screw body 1 from tilting when fixed, thereby improving the strength during use, and the drilled wood chips will pass through the spiral groove 304 and the chip groove 105 The drywall screw body 1 is discharged to the outside to prevent excessive accumulation in the hole. As the drywall screw body 1 rotates, the non-return teeth 203 in the non-return assembly 2 will slowly contact the object, and the angle between the non-return claw 202 and the drywall screw body 1 will gradually increase, and the resilient member 201 will be deformed, and at the same time, an elastic force will be provided to the non-return claw 202. Due to the setting of the non-return teeth 203, the elastic force will make the non-return teeth 203 tightly grasp the object, play a non-return effect, prevent the drywall screw body 1 from exiting the hole due to external vibration, and improve the reliability of the drywall screw body 1 when in use.
