Description

Technical Field

[0001] This utility model relates to the field of self-tapping taps, and in particular to a detachable self-tapping tap. Background Technology

[0002] A self-tapping tap is a specially designed threading tool that can directly screw into and cut matching threads in materials that have not been pre-drilled. This tap combines the functions of drilling and tapping, simplifying the processing flow and improving work efficiency. Its unique spiral blade design allows self-tapping taps to easily penetrate various materials such as metals and plastics, while ensuring the accuracy and strength of the threads. It is widely used in industries such as automotive, electronics, and machinery, and is one of the indispensable tools in manufacturing and maintenance.

[0003] However, in the existing technology, since self-tapping taps are often welded to the connecting sleeve, it is often necessary to disassemble the connecting sleeve together when replacing them, which greatly affects the replacement speed. Utility Model Content

[0004] The purpose of this invention is to provide a detachable self-tapping tap to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a detachable self-tapping tap, comprising a connecting sleeve, a threaded hole on the front side of the connecting sleeve, a guide hole near the threaded hole on the front side of the connecting sleeve, a guide rod movably connected inside the guide hole, a short block fixedly connected to the rear side of the guide rod, a retaining ring fixedly connected to the right side of the short block, a retaining rod fixedly connected to the rear side of the retaining ring, a retaining ring movably connected inside the retaining ring, a bolt fixedly connected to the front side of the retaining ring, a connecting ring on the right side of the connecting sleeve, a tap rod fixedly connected to the right side of the connecting ring, a fixing rod fixedly connected to the middle of the left side of the connecting ring, and a retaining hole inside the fixing rod.

[0006] Preferably, a support rod is fixedly connected to the left side of the connecting sleeve, a limit hole is formed on the inner wall of the support rod, a fixing bolt is provided on the inner wall of the support rod near the limit hole, an adjusting rod is movably connected inside the support rod, an assembly block is fixedly connected to the left side of the adjusting rod, and a fixing block is fixedly connected to the other side of the adjusting rod.

[0007] Preferably, the fixed block has a telescopic rod inside, a spring is sleeved on the outside of the telescopic rod, a slider is fixedly connected to the front side of the telescopic rod, a locking block is fixedly connected to the other side of the slider, and a long rod is provided inside the fixed block near the telescopic rod.

[0008] Preferably, the lever is movably connected to the retaining ring via a retaining ring.

[0009] Preferably, the slider slides inside the fixed block via a telescopic rod and a spring.

[0010] Preferably, the number of the card blocks is two sets, and they are symmetrically arranged about the center line of the fixed block.

[0011] Using the above technical solution, by rotating the bolt, the retaining ring and retaining ring move to one side under the action of the threaded hole inside the connecting sleeve. The retaining rod slides out from the inside of the retaining hole, releasing the limitation on the fixing rod. Pulling the connecting ring, the fixing rod slides inside the connecting sleeve, realizing the disassembly of the tap rod. Similarly, by sliding the fixing rod into the inside of the connecting sleeve and rotating the bolt in the opposite direction, the bolt pushes the retaining ring and retaining ring to move in the opposite direction, and the retaining rod enters the inside of the retaining hole, realizing the limitation on the fixing rod. During this process, the cooperation between the guide rod and the guide hole effectively prevents the retaining rod from deviating during the movement, significantly improving the stability of operation. The tap rod can be quickly installed and removed through components such as bolts, retaining rings, retaining rings, retaining rods, and fixing rods, and can be replaced individually after long-term use without the need for overall disassembly, greatly improving the replacement rate.

[0012] By adopting the above technical solution, rotating the fixing bolt and pushing the locking block causes the slider to compress the telescopic rod and spring. The locking block slides out from the inside of the limiting hole and pulls the assembly block to one side. The assembly block drives the adjusting rod to slide inside the connecting sleeve. When the locking block reaches the position of another set of limiting holes, the spring rebounds and causes the telescopic rod to push the locking block into another set of limiting holes. The fixing bolt is rotated in the opposite direction, and one side of the fixing bolt is pressed against the adjusting rod, realizing secondary fixation, that is, completing the extension of the connecting sleeve. The length of the connecting sleeve can be adjusted by components such as the fixing block, telescopic rod, spring, locking block, limiting hole, and fixing bolt, thereby meeting different usage requirements and reducing the limitations of the tap in use.

[0020] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0021] Example 1

[0022] Please see Figures 1-6 This utility model provides a technical solution: a detachable self-tapping tap, including a connecting sleeve 1, a threaded hole 3 on the front side of the connecting sleeve 1, a guide hole 22 near the threaded hole 3 on the front side of the connecting sleeve 1, a guide rod 23 movably connected inside the guide hole 22, a short block 24 fixedly connected to the rear side of the guide rod 23, a retaining ring 6 fixedly connected to the right side of the short block 24, a retaining rod 7 fixedly connected to the rear side of the retaining ring 6, a retaining ring 5 movably connected inside the retaining ring 6, a bolt 4 fixedly connected to the front side of the retaining ring 5, a connecting ring 2 on the right side of the connecting sleeve 1, a tap rod 10 fixedly connected to the right side of the connecting ring 2, a fixing rod 8 fixedly connected to the middle of the left side of the connecting ring 2, a retaining hole 9 inside the fixing rod 8, and the retaining rod 7 movably connected to the retaining ring 5 through the retaining ring 6.

[0023] Specifically, rotating bolt 4 causes the retaining ring 5 and retaining ring 6 to move to one side under the action of the threaded hole 3 inside the connecting sleeve 1. The retaining rod 7 slides out from inside the retaining hole 9, releasing the restriction on the fixing rod 8. Pulling the connecting ring 2 causes the fixing rod 8 to slide inside the connecting sleeve 1, thus disassembling the tap rod 10. Similarly, sliding the fixing rod 8 into the connecting sleeve 1 and rotating bolt 4 in the opposite direction causes bolt 4 to push the retaining ring 5 and retaining ring 6 to move in the opposite direction. The retaining rod 7 enters inside the retaining hole 9, thus limiting the fixing rod 8. During this process, the cooperation between the guide rod 23 and the guide hole 22 effectively prevents the retaining rod 7 from shifting during movement, significantly improving the stability of operation. The tap rod 10 can be quickly installed and removed through components such as bolt 4, retaining ring 5, retaining ring 6, retaining rod 7, and fixing rod 8, allowing for individual replacement during long-term use without overall disassembly, greatly improving the replacement rate.

[0024] Example 2

[0025] Please see Figures 1-6 This utility model provides a technical solution: a detachable self-tapping tap, wherein a support rod 11 is fixedly connected to the left side of the connecting sleeve 1, a limit hole 12 is opened on the inner wall of the support rod 11, a fixing bolt 13 is provided on the inner wall of the support rod 11 near the limit hole 12, an adjusting rod 14 is movably connected inside the support rod 11, an assembly block 15 is fixedly connected to the left side of the adjusting rod 14, a fixing block 16 is fixedly connected to the other side of the adjusting rod 14, a telescopic rod 17 is provided inside the fixing block 16, a spring 18 is sleeved on the outside of the telescopic rod 17, a slider 19 is fixedly connected to the front side of the telescopic rod 17, a locking block 20 is fixedly connected to the other side of the slider 19, a long rod 21 is provided inside the fixing block 16 near the telescopic rod 17, the slider 19 slides inside the fixing block 16 through the telescopic rod 17 and the spring 18, and there are two sets of locking blocks 20, which are symmetrically arranged about the center line of the fixing block 16.

[0026] Specifically, rotating the fixing bolt 13 and pushing the locking block 20 causes the slider 19 to compress the telescopic rod 17 and the spring 18. The locking block 20 slides out from the inside of the limiting hole 12 and pulls the assembly block 15 to one side. The assembly block 15 drives the adjusting rod 14 to slide inside the connecting sleeve 1. When the locking block 20 reaches the position of another set of limiting holes 12, the spring 18 rebounds and causes the telescopic rod 17 to push the locking block 20 into another set of limiting holes 12. The fixing bolt 13 is rotated in the opposite direction, and one side of the fixing bolt 13 is pressed against the adjusting rod 14 to achieve secondary fixation, that is, to complete the extension of the connecting sleeve 1. The length of the connecting sleeve 1 can be adjusted by components such as the fixing block 16, telescopic rod 17, spring 18, locking block 20, limiting hole 12, and fixing bolt 13, so as to meet different usage requirements and reduce the limitations of the tap in use.

[0027] Working Principle: When using this self-tapping tap, firstly, it is installed on the connector of the external drive device via the assembly block 15. Then, the length of the connecting sleeve 1 is extended according to usage requirements. Specifically, the fixing bolt 13 is rotated and the locking block 20 is pushed. The locking block 20 causes the slider 19 to compress the telescopic rod 17 and the spring 18. The locking block 20 slides out from the inside of the limiting hole 12 and pulls the assembly block 15 to one side. The assembly block 15 drives the adjusting rod 14 to slide inside the connecting sleeve 1. When the locking block 20 reaches the position of another set of limiting holes 12, the spring 18 rebounds, causing the telescopic rod 17 to push the locking block 20 into the other set of limiting holes 12. The fixing bolt 13 is then rotated in the opposite direction, and one side of the fixing bolt 13 is pressed tightly against the adjusting rod 14, achieving secondary fixation, thus completing the extension of the connecting sleeve 1. The length of the connecting sleeve 1 can be adjusted through components such as the fixing block 16, telescopic rod 17, spring 18, locking block 20, limiting hole 12, and fixing bolt 13, thereby meeting different usage requirements and reducing [the length of the connecting sleeve 1]. This design reduces the limitations of the tap during use. After adjustment, it can be used normally. When the tap rod 10 needs to be replaced after long-term use, rotating the bolt 4 causes the retaining ring 5 and retaining ring 6 to move to one side under the action of the threaded hole 3 inside the connecting sleeve 1. The retaining rod 7 slides out from the inside of the retaining hole 9, releasing the restriction on the fixing rod 8. Pulling the connecting ring 2 causes the fixing rod 8 to slide inside the connecting sleeve 1, thus disassembling the tap rod 10. Similarly, sliding the fixing rod 8 into the inside of the connecting sleeve 1 and rotating the bolt 4 in the opposite direction causes the bolt 4 to push the retaining ring 5 and retaining ring 6 to move in the opposite direction. The retaining rod 7 enters the inside of the retaining hole 9, thus limiting the fixing rod 8. During this process, the cooperation between the guide rod 23 and the guide hole 22 effectively prevents the retaining rod 7 from shifting during movement, significantly improving the stability of operation. The components such as the bolt 4, retaining ring 5, retaining ring 6, retaining rod 7, and fixing rod 8 allow for quick installation and removal of the tap rod 10, enabling it to be replaced individually after long-term use without overall disassembly, greatly improving the replacement speed.

[0028] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
