Description

Technical Field

[0001] This utility model relates to the field of dust-free cotton swab technology, specifically to a foldable dust-free cotton swab. Background Technology

[0002] Dust-free swabs are used for cleaning precision instruments, electronic equipment, optical lenses, and other items requiring extremely high cleanliness. The main difference between them and ordinary swabs lies in their materials and manufacturing processes, which effectively reduce the generation and residue of microparticles. Dust-free swabs typically use polyester fibers, nylon, or other materials for the swab tip. These materials are inherently lint-free, have fine fibers, and do not leave fibrous residue like cotton during cleaning. The wooden or plastic sticks are also usually specially treated to reduce microparticle shedding.

[0003] While existing foldable dust-free cotton swabs can increase the length of the swab, they cannot be adjusted in length. That is, the length of the swab is only the length when folded and the length when unfolded. This can only meet the cleaning needs of specific environments, but cannot meet the cleaning needs of various environments, and its practicality is poor. Utility Model Content

[0004] The purpose of this invention is to provide a foldable dust-free cotton swab to address the aforementioned shortcomings in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A foldable, dust-free cotton swab includes a first rod and a second rod. One end of the second rod is rotatably connected to the first rod and can slide along the length of the first rod. A cotton swab head is fixedly connected to the other end of the second rod. The first rod has multiple slots, each slot being opened along the length of the first rod. A locking rod adapted to the slot is fixedly connected to the second rod. The first rod also has a locking fastener for limiting the rotation of the second rod relative to the first rod.

[0007] Furthermore, a rotating rod is fixedly connected to one end of the second rod, and the rotating rod is slidably connected to a groove on the first rod.

[0008] Furthermore, a placement groove is provided on the first rod body, and when the rotating rod of the second rod body is at one end of the sliding groove, the cotton swab head is located in the placement groove.

[0009] Furthermore, the locking device includes a locking ring slidably connected to the first rod body, a locking block is fixedly provided on the locking ring, a locking groove is provided on the locking ring, and the locking rod and the locking groove are locked by friction.

[0010] Furthermore, a positioning block is fixedly connected to the locking ring, and the positioning block is slidably connected to the positioning groove on the first rod.

[0011] Furthermore, the end of the first rod is provided with a mounting groove that is compatible with the locking block.

[0012] In the above technical solution, the foldable dust-free cotton swab provided by this utility model has the following beneficial effects:

[0013] By using a first and second rod, the second rod is rotated during use to disengage the locking lever from the slot, and the second rod is then pulled along the length of the first rod. When it reaches the desired position, rotating the second rod causes the locking lever on the second rod to engage with the slot on the first rod, thereby adjusting the length of the cotton swab. A locking mechanism further restricts the rotation of the second rod for ease of use. This invention allows for self-adjustment of the cotton swab length to meet cleaning needs in various environments, and its simple structure makes it easy to use.

[0014] It should be understood that the foregoing general description and the following detailed description are exemplary and illustrative only, and are not intended to limit this disclosure.

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure. All other embodiments obtained by those skilled in the art based on the described embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

[0027] Please see Figure 1-5 A foldable dust-free cotton swab includes a first rod 1 and a second rod 2. One end of the second rod 2 is rotatably connected to the first rod 1 and can slide along the length of the first rod 1. The other end of the second rod 2 is fixedly connected to a cotton swab head 21. The first rod 1 has multiple slots 11, each slot 11 being opened along the length of the first rod 1. The second rod 2 is fixedly connected to a locking rod 22 that matches the slot 11. The first rod 1 is also provided with a locking fastener 3 for limiting the rotation of the second rod 2 relative to the first rod 1.

[0028] By using the first rod 1 and the second rod 2, the second rod 2 is rotated during use to disengage the locking lever 22 from the locking slot 11, and the second rod 2 is pulled along the length of the first rod 1. When it reaches the appropriate position, the second rod 2 is rotated so that the locking lever 22 on the second rod 2 extends into the locking slot 11 on the first rod 1, thereby adjusting the length of the cotton swab. The rotation of the second rod 2 is then restricted by the locking fastener 3 for ease of use. This invention can automatically adjust the length of the cotton swab to meet cleaning needs in various environments, and its structure is simple and easy to use.

[0029] Furthermore, a rotating rod 23 is fixedly connected to one end of the second rod 2, and the rotating rod 23 is slidably connected in a groove 12 on the first rod 1. When the second rod 2 rotates, the locking rod 22 rotates about the central axis of the rotating rod 23 to the corresponding locking groove 11; the groove 12 can prevent the second rod 2 from disengaging from the second rod 2.

[0030] Furthermore, a placement groove 13 is provided on the first rod body 1, and when the rotating rod 23 of the second rod body 2 is at one end of the sliding groove 12, the cotton swab head 21 is located in the placement groove 13.

[0031] Furthermore, the locking device 3 includes a locking ring 31 slidably connected to the first rod body 1, a locking block 32 fixedly disposed on the locking ring 31, and a locking groove 33 formed on the locking ring 31. The locking rod 22 and the locking groove 33 are locked together by friction.

[0032] When the locking rod 22 falls into the locking groove 11, the locking ring 31 drives the locking groove 33 to move until the locking groove 33 engages with the locking rod 22. The friction between the locking groove 33 and the locking rod 22 restricts the relative movement of the locking ring 31 and the locking rod 22. At this time, the locking block 32 abuts against the second rod 2, thereby restricting the rotation of the second rod 2 to facilitate cleaning operations.

[0033] Furthermore, a positioning block 34 is fixedly connected to the locking ring 31, and the positioning block 34 is slidably connected to the positioning groove on the first rod 1. The slidable connection between the positioning block 34 and the positioning groove can guide the locking ring 31 to move along the length direction of the first rod 1 and limit the range of movement of the locking ring 31 to prevent the locking ring 31 from detaching from the first rod 1.

[0034] Furthermore, the end of the first rod 1 is provided with a mounting groove 14 that is compatible with the locking block 32.

[0035] Working principle: During use, rotating the second rod 2 causes the locking rod 22 to disengage from the slot 11. Due to the constraint of the rotating rod 23 and the sliding groove 12, pulling the second rod 2 causes it to move along the length of the first rod 1. When it moves to the appropriate position, rotating the second rod 2 causes the locking rod 22 on the second rod 2 to extend into the slot 11 on the first rod 1, thereby adjusting the length of the cotton swab. Then, moving the locking ring 31 until the locking groove 33 engages with the locking rod 22, and the friction between the locking groove 33 and the locking rod 22 restricts the relative movement of the locking ring 31 and the locking rod 22. At this time, the locking block 32 abuts against the second rod 2, thereby restricting the rotation of the second rod 2 to facilitate cleaning operations.

[0036] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
