Description

Technical Field

[0001] This utility model relates to the technical field of locking devices, and in particular to a locking structure and locking device for a screw. Background Technology

[0002] The current installation process for faucets involves first screwing one end of the inlet screw rod onto the faucet body, then passing the other end of the inlet screw rod through the basin or sink, and finally screwing it into the nut. However, most existing inlet screw rod installations are performed in the following way: Wrap Teflon tape (or apply an appropriate amount of sealant, or install a sealing ring) around the external thread of the inlet screw and / or the internal thread of the faucet valve body. Use a wrench to screw the inlet screw into the corresponding interface of the faucet valve body. Be careful to align the threads and avoid misalignment. Therefore, most installations are currently done manually with a wrench, which is inefficient and labor-intensive.

[0003] In view of this, the inventor has designed a locking structure for the screw, which leads to this invention. Utility Model Content

[0021] To make the technical problem to be solved, the technical solution, and the beneficial effects of this utility model clearer and more understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0022] Please see Figures 1 to 7 This invention relates to a screw locking structure for locking screw 001, comprising: a screw sleeve 10, a rotating rod 20, and a guide rod 30. The screw sleeve 10 is hollow inside, and one end is threadedly connected to the screw 001. Two guide grooves 13 communicating with the interior are provided on the screw sleeve 10. One end of the rotating rod 20 is rotatably connected to the screw sleeve 10. The rotating rod is connected to the screw sleeve 10 via the guide rod 30, which is embedded in the rotating rod 20, with both ends located within the guide grooves 13. The guide rod 30 moves within the guide grooves 13 to allow the end face of the rotating rod 20 to abut against or move away from the end face of the screw 001. The locking structure of the screw 001 of this invention connects the rotating rod 20 to the screw sleeve 10 via the guide rod 30. Therefore, when used with a pneumatic screwdriver, the screw 001 can be connected without the need for manual installation using a wrench.

[0023] Please refer to the details. Figure 3 The screw sleeve 10 has a through hole 11 inside to make its interior hollow. One end of the through hole 11 has a first internal thread hole 12 for threaded connection with the screw 001, and the other end is rotatably connected to the rotating rod 20.

[0024] Please refer to details. Figure 6 , 7 The locking structure of this utility model is mainly for the following screw 001. The screw 001 includes a threaded part 002 and a first extension part 003 disposed below the threaded part 002. The first internal threaded hole 12 in the screw sleeve 10 is threadedly connected to the threaded part 002. When locked, the first extension part 003 can tightly abut against the rotating rod 20 to ensure the screw 001 is tightened.

[0025] Please refer to details. Figure 1 , 3One end of the rotating rod 20, connected to the threaded sleeve 10, is provided with a first through hole 201 for connecting to the guide rod 30. The middle part of the guide rod 30 is located in the first through hole 201, and both ends are located in two guide grooves 13 respectively. The guide grooves 13 are inclined, specifically, the guide grooves 13 form an angle α with the end face; wherein, the angle α is 4-8°, preferably 5°. The two guide grooves 13 are correspondingly arranged so that both ends of the guide rod 30 are raised or lowered synchronously, and the raising and lowering of the guide rod 30 is driven by the rotation of the rotating rod 20.

[0026] Please refer to details. Figure 2 The rotating rod 20 includes a rotating portion 21 rotatably connected to the inside of the threaded sleeve 10, and a second extension 22 disposed on the rotating portion 21. A first through hole 201 is disposed on the rotating portion 21, and the central axis of the first through hole 201 is perpendicular to the central axis of the rotating portion 21. The second extension 22 can be connected to a pneumatic screwdriver or other tool that can drive its rotation. The rotating portion 21 and the second extension 22 are integrally formed.

[0027] Please refer to details. Figure 3 The guide rod 30 and the rotating rod 20 are connected by an interference fit. During installation, first insert the rotating part 21 of the rotating rod 20 into the threaded sleeve 10, with the first through hole 201 corresponding to the guide groove 13. Then, insert the guide rod 30 into one of the guide grooves 13 and embed it into the first through hole 201. Use a tapping method to embed the guide rod 30 into the first through hole 201, continuing to tap until both ends of the guide rod 30 are located in the two guide grooves 13 respectively. The guide rod 30, the rotating rod 20, and the threaded sleeve 10 are all metal parts.

[0028] Please refer to details. Figure 6 , 7 The guide groove 13 of this utility model is inclined, and the guide groove 13 preferably adopts a 5-degree angle. When the screw 001 needs to be locked, the top of the rotating rod 20 is tightly abutted against the bottom of the screw 001 to ensure that the screw 001 is locked on the faucet valve core or valve body. After the screw 001 is locked, the air screw reverses, and the rotating rod 20 disengages from the locking of the screw 001, causing the screw sleeve 10 to exit together.

[0029] This utility model also provides a locking device for a screw 001, including a locking structure and a pneumatic screwdriver. The rotating rod 20 of the locking structure is connected to the pneumatic screwdriver. The locking structure adopts the construction of a locking structure for a screw 001.

[0030] In summary, the locking structure of the screw of this utility model connects the rotating rod to the screw sleeve through the guide rod. Therefore, when used with an air screwdriver, the screw can be locked without the need for manual installation using a wrench.

[0031] The present invention has been described above with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made using the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution to other situations without modification, are all within the protection scope of the present invention.
