Description

Technical Field

[0001] This utility model relates to the field of precision equipment cleaning technology, specifically to a structure for preventing the bending of squeezed cotton swabs. Background Technology

[0002] With the rapid development of industries such as semiconductors, consumer electronics, and optical instruments, the surface cleaning requirements for high-precision electronic equipment and components are becoming increasingly stringent. It is necessary to remove impurities such as micron-level dust and oil to ensure equipment performance and service life. At the same time, there are extremely high requirements for dust-free and scratch-free cleaning and wiping. Squeeze-type cotton swabs, also known as wiping sticks, are key tools for such operations. They are usually composed of a hollow wiping rod that stores wiping liquid and a wiping cotton head attached to one end of the rod. When in use, by squeezing the rod, the internal wiping liquid seeps out to the cotton head to achieve immersion cleaning.

[0003] To ensure the liquid storage function, the wiping rod of the squeeze-type cotton swab has a hollow structure, which greatly reduces its bending strength. When performing wiping tasks that require applying a certain pressure or delicate operation, the rod is very easy to bend or even break. A bent squeeze-type cotton swab is not only difficult to operate, but also causes the cleaning operation to be interrupted, thus affecting the cleaning effect of high-precision equipment.

[0004] Therefore, those skilled in the art have provided a structure to prevent the swabs from bending when squeezed, in order to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to provide an anti-bending structure for squeezed cotton swabs to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] The anti-bending structure of the squeeze swab includes the swab body and also includes:

[0008] The support protective sleeve is semi-circular in shape and is used to attach to and support the side surface of the hollow wiping rod of the swab body;

[0009] At least one locking mechanism is respectively provided at the top and bottom of the swab body. Each locking mechanism includes a first semicircular block fixedly connected to one side of the support protective sleeve, and a second semicircular block rotatably connected to the first semicircular block via a rotating shaft. The first semicircular block and the second semicircular block can open and close around the rotating shaft to jointly hug the corresponding part of the swab body.

[0010] And a plug-in locking component for fixing the second semicircular block to the first semicircular block when the second semicircular block is closed.

[0011] As a further embodiment of this utility model: the plug-in locking assembly includes: a plug block disposed at the bottom of the second semicircular block, the plug block having a limiting hole; a slot disposed inside one side of the first semicircular block for accommodating the plug block; a notch disposed inside the other side of the first semicircular block, the notch having a rotating shaft fixedly connected thereto; a movable limiting rod disposed inside the first semicircular block, the limiting rod being movable between a locked position and an unlocked position, the limiting rod being inserted into the limiting hole of the plug block when in the locked position.

[0012] As a further embodiment of this utility model: a connecting hole is provided on one side of the inner wall of the slot, a reset spring is provided in the slot, and the reset spring is connected to the compression plate, and the limiting rod is fixed on the compression plate.

[0013] As a further embodiment of this utility model: a synchronizing rod is movably connected inside the connecting hole, and one end of the synchronizing rod is connected to the extrusion plate, while the other end extends out of the first semicircular block and is connected to a pull block. When the pull block is pulled, the extrusion plate is driven by the synchronizing rod to compress the first reset spring, causing the limiting rod to exit from the limiting hole.

[0014] As a further improvement of this utility model, it also includes a connection point reinforcement mechanism, which is used to reinforce the connection between the hollow wiping rod and the wiping cotton head with a clamp. The connection point reinforcement mechanism includes a fixed petal and a movable petal. One end of the fixed petal is connected to the first semicircular block, and the movable petal is connected above the fixed petal by a compression spring. The compression spring provides a pre-tightening force to move the movable petal away from the fixed petal.

[0015] As a further improvement of this utility model: a locking hole is provided inside the fixed petal, and a locking rod is movably provided inside the movable petal. The locking rod can be selectively inserted into the locking hole or withdrawn from the locking hole.

[0016] As a further embodiment of this utility model: a groove is provided inside the movable petal, a positioning frame is fixedly connected inside the groove, a second return spring is fixedly connected to the top of the positioning frame, a button is connected to the top of the locking rod, and the second return spring is connected below the button. The second return spring provides a preload force to keep the locking rod in an insertion tendency; the button can be pressed down and rotated to unlock and relock the locking rod.

[0017] As a further embodiment of this utility model: a connecting block is fixedly connected to the other side of the first semicircular block, and a conical limiting sleeve is fixedly connected to the other side of the connecting block.

[0018] As a further improvement of this utility model: the conical limiting sleeve is made of silicone material, and the inner diameter of the conical limiting sleeve gradually decreases in the direction away from the connecting block.

[0019] As a further improvement of this utility model: two arc-shaped reinforcing blocks are symmetrically arranged on both sides of the support protective sleeve, and the first semi-circular block is fixedly connected to the arc-shaped reinforcing block.

[0020] Compared with the prior art, the beneficial effects of this utility model are:

[0021] 1. By setting up a support protective sleeve, a first semicircular block, and a second semicircular block, the support protective sleeve can support the hollow wiping rod of the swab body. At the same time, the first and second semicircular blocks lock and fix the bottom and top of the hollow wiping rod respectively, which greatly disperses the bending stress on the rod body. This fundamentally solves the problem of low bending strength and easy breakage of the hollow wiping rod due to its structural characteristics, and ensures the continuity of high-precision equipment cleaning operations.

[0022] 2. By setting fixed and movable flaps, the connection between the hollow wiping rod and the wiping head of the swab body can be reinforced in a clamp-like manner, providing stable anti-bending protection at the connection point, while avoiding the cumbersome operation of traditional reinforcement methods, and further improving the targeted protection of vulnerable parts of the swab body.

[0023] 3. By setting a conical limiting sleeve, the bottom of the hollow wiping rod is positioned, and the flexible inner wall fits against the outer wall of the rod, avoiding hard contact that could damage the liquid storage cavity of the wiping rod, thus ensuring that the liquid storage function of the squeeze-type cotton swab is not affected.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Example 1

[0035] Reference Figures 1-8This embodiment provides a compression swab anti-bending structure, including a swab body 1, and further including: a support protective sleeve 2, which is semi-circular in shape and used to fit and support the side surface of the hollow wiping rod of the swab body 1; at least one locking mechanism, respectively disposed at the top and bottom of the swab body 1, each locking mechanism including a first semi-circular block 4 fixedly connected to one side of the support protective sleeve 2, and a second semi-circular block 8 rotatably connected to the first semi-circular block 4 via a rotating shaft 6, the first semi-circular block 4 and the second semi-circular block 8 being able to open and close around the rotating shaft 6 to jointly embrace the corresponding part of the swab body 1; and a plug-in locking component, used for... When the second semicircular block 8 closes, it is fixedly connected to the first semicircular block 4. The insertion locking assembly includes: an insertion block 9 disposed at the bottom of the second semicircular block 8, with a limiting hole 10 formed inside the insertion block 9; a slot 7 formed inside one side of the first semicircular block 4 to accommodate the insertion block 9; a notch 5 formed inside the other side of the first semicircular block 4, with a rotating shaft 6 fixedly connected inside the notch 5; and a movable limiting rod 16 disposed inside the first semicircular block 4, which can move between a locked position and an unlocked position. In the locked position, the limiting rod 16 is inserted into the limiting hole 10 of the insertion block 9. A connecting hole 11 is formed on one side of the inner wall of the slot 7. A reset spring 14 is installed in slot 7 and is connected to the extrusion plate 15. The limiting rod 16 is fixed on the extrusion plate 15. A synchronizing rod 12 is movably connected inside the connecting hole 11. One end of the synchronizing rod 12 is connected to the extrusion plate 15, and the other end extends out of the first semicircular block 4 and is connected to a pull block 13. When the pull block 13 is pulled, the extrusion plate 15 is driven by the synchronizing rod 12 to compress the reset spring 14, causing the limiting rod 16 to exit from the limiting hole 10. In use, the hollow wiping rod of the wiping swab body 1 is slowly inserted into the arc-shaped through groove of the support protective sleeve 2, and at the same time, the bottom of the hollow wiping rod naturally inserts into the conical... Inside the limiting sleeve 27, the flexible inner wall of the conical limiting sleeve 27 will fit against the outer wall of the bottom of the hollow wiping rod. Then, the user pulls the pull block 13, which drives the squeezing plate 15 to squeeze the return spring 14 through the synchronous rod 12. Then, the second semicircular block 8 is rotated so that it rotates around the rotating shaft 6 until the insert 9 at the bottom of the second semicircular block 8 is fully inserted into the slot 7 of the first semicircular block 4. When the insert 9 is fully inserted into the slot 7, the pull block 13 is released. Under the force of the return spring 14, the limiting rod 16 is inserted into the limiting hole 10. Since there are two of the first semicircular block 4 and the second semicircular block 8, the bottom and top of the hollow wiping rod are fixed respectively.

[0036] Example 2

[0037] Reference Figures 1-8This embodiment is based on the previous embodiment, but differs in that it also includes a connection point reinforcement mechanism. This mechanism is used to reinforce the connection between the hollow wiping rod and the wiping cotton head. It includes a fixed flap 17 and a movable flap 20. One end of the fixed flap 17 is connected to the first semicircular block 4. The movable flap 20 is connected above the fixed flap 17 via a compression spring 18. The compression spring 18 provides a pre-tightening force to move the movable flap 20 away from the fixed flap 17. A locking hole 19 is provided inside the fixed flap 17, and a locking rod 25 is movably disposed inside the movable flap 20. The locking rod 25 can be selectively inserted into the locking hole 19. The moving lever 20 has a groove 21 inside, which is fixedly connected to a positioning frame 22. A return spring 23 is fixedly connected to the top of the positioning frame 22. A button 24 is connected to the top of the locking lever 25. The return spring 23 is connected below the button 24. The return spring 23 provides a preload force to keep the locking lever 25 in the insertion direction. The button 24 can be pressed down and rotated to unlock and relock the locking lever 25. A connecting block 26 is fixedly connected to the other side of the first semicircular block 4. A conical limiting sleeve 27 is fixedly connected to the other side of the connecting block 26. The conical limiting sleeve 27 is made of silicon. Made of rubber, the inner diameter of the conical limiting sleeve 27 gradually decreases away from the connecting block 26. Two arc-shaped reinforcing blocks 3 are symmetrically arranged on both sides of the supporting protective sleeve 2. The first semicircular block 4 is fixedly connected to the arc-shaped reinforcing block 3. Then, press down on the moving petal 20 and simultaneously squeeze the compression spring 18. When the moving petal 20 and the fixed petal 17 are tightly fitted, the protruding part of the locking rod 25 is located in the locking hole 19. At this time, press the button 24 to squeeze the second return spring 23, so that the protruding part of the locking rod 25 moves out of the locking hole 19. Then rotate the button 24 ninety degrees and release it. Under the action of the second return spring 23, the locking rod is locked. The protruding part of 25 moves upward and engages with the outer surface of the fixed petal 17 to fix the moving petal 20, thereby reinforcing the connection between the hollow wiping rod and the wiping head of the swab body 1. Finally, when the swab body 1 needs to be replaced, press the button 24 and rotate it 90 degrees in the opposite direction. The rebound force of the compression spring 18 will move the moving petal 20 upward, opening the clamp at the connection. At the same time, pull the pull block 13 outward, and drive the limiting rod 16 to completely exit from the limiting hole 10 of the insertion block 9 through the synchronizing rod 12. At this time, the second semicircular block 8 can be rotated in the opposite direction to open it, release the fixation, and the swab body 1 can be taken out.
