[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] 1. The inner barrel cleaning device for the production and processing of optical instrument lens barrels realizes the cleaning of the lens barrel by setting structures such as a shaft ring, a film, and a cleaning barrel. The shaft ring makes a circular motion together with the screw shaft. When the handle drives the screw shaft to spirally rise inside the inner ring, the inner wall of the lens barrel is cleaned by the shaft ring, and it slowly rises with the screw shaft until it rises above the lens barrel opening. While the screw shaft rotates, the brush barrel on the outer ring of the shaft ring fits tightly against the inner wall of the lens barrel, and the brush barrel makes a circular motion along the cylinder to clean the inner wall of the lens barrel. The brush barrel cleans the inner wall of the lens barrel in a spiral manner to avoid wear on the inner wall of the lens barrel caused by cleaning at a single position, and the cleaning barrel itself makes a circular motion around the card strip to completely clean the bottom of the lens barrel, achieving a uniform cleaning effect.

[0013] 2. The inner cylinder cleaning device for the production and processing of optical instrument lens barrels realizes the limitation of the screw shaft by setting structures such as screw shaft, ratchet, and pressing column. When the screw shaft rotates counterclockwise, the ratchet is stuck between the teeth, so that the screw shaft cannot rotate counterclockwise. When the shaft ring is located at the bottom of the lens barrel and follows the screw shaft to spiral up to the lens barrel opening, the shaft ring is removed and replaced with a new shaft ring, and the pressing column is pressed to make the ratchet disengage from between the teeth to release the limitation on the screw shaft. At this time, the handle can be turned to make the screw shaft rotate in the opposite direction and adjusted to a length that is connected to the inside of the lens barrel, which has the effect of limiting the position and rotation direction of the screw shaft.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-Figure 4 The invention discloses an inner cylinder cleaning device for producing and processing an optical instrument lens barrel, comprising a shell 1, wherein the shell 1 comprises a gear ring 11, a wire ring 12 is fixedly installed at the bottom of the gear ring 11, an inner ring of the wire ring 12 is provided with an internal thread 121, and the internal thread 121 is matched with the thread at the opening of the lens barrel, a fixing groove is provided inside the gear ring 11, an inner ring 13 is fixedly installed inside the fixing groove, a thread groove 131 is provided inside the inner ring 13, and a functional cavity 132 is provided on one side inside the inner ring 13.

[0023] See also Figure 1-Figure 5 A fixing column 133 is fixedly installed inside the functional cavity 132, and a pawl 134 is rotatably installed on the outer ring of the fixing column 133. A retaining spring is provided between the outer ring of the fixing column 133 and the inside of the pawl 134, which is used to return the pawl 134 to its original position. A limiting spring 135 is fixedly connected between one side of the pawl 134 and the inner wall of the functional cavity 132. This device is used to prevent the pawl 134 from reversing. A connector 136 is fixedly installed on the outside of the pawl 134 on one side of the limiting spring 135. A through groove is provided inside the gear ring 11 and the inner ring 13, and a pressing column 137 is slidably installed inside the through groove. One end of the pressing column 137 is located inside the connector 136, and a rotating shaft is fixedly installed inside the connector 136 through the pressing column 137, and the rotating shaft limits the connection between the connector 136 and the pressing column 137.

[0024] When the screw shaft 2 rotates, the pawl 134 will be stuck inside the teeth along with the movement of the teeth on the outer ring of the screw shaft 2 due to the limitation of the retaining spring. When the screw shaft 2 rotates clockwise, there is no resistance to the rotation. When the screw shaft 2 rotates counterclockwise, the pawl 134 is stuck between the teeth, so that the screw shaft 2 cannot rotate counterclockwise. When the shaft ring 5 is located at the bottom of the lens barrel, after following the screw shaft 2 to spiral up to the lens barrel opening, the shaft ring 5 is removed and replaced with a new shaft ring 5, and the pressing column 137 is pressed to disengage the pawl 134 from between the teeth to release the limitation on the screw shaft 2. At this time, the handle 3 can be turned to make the screw shaft 2 rotate in the opposite direction and adjusted to a length that is connected to the inside of the lens barrel.

[0025] See also Figure 1-Figure 2 A screw shaft 2 is rotatably installed inside the shell 1, and a tooth groove and a thread are provided on the outer ring of the screw shaft 2. The tooth groove is matched with the ratchet 134, and the thread is matched with the functional cavity 132. A handle 3 is fixedly installed on the top of the screw shaft 2. The screw shaft 2 is driven to rotate by holding the handle 3. When the handle 3 is held and rotated clockwise, the screw shaft 2 will spiral up inside the shell 1. When the handle 3 is rotated counterclockwise, the screw shaft 2 will spiral down inside the shell 1. A film 4 is fixedly installed on the bottom of the screw shaft 2. The film 4 is located below the shaft ring 5 to limit the moving distance of the shaft ring 5. The outer ring of the screw shaft 2 is fixedly sleeved with the shaft ring 5, and the shaft ring 5 is located above the film 4. A clamping strip 6 is fixedly installed on the bottom of the film 4, and a cleaning cylinder 7 is rotatably sleeved on the outer ring of the clamping strip 6.

[0026] See also Figure 1-Figure 6 The outer ring of the shaft ring 5 is provided with a side groove 51, and a cylinder is evenly fixedly installed in the inner ring of the side groove 51. The outer ring of the cylinder is rotatably sleeved with a brush cylinder 52, and the brush cylinder 52 is a fluff brush cylinder, and the outer ring of the brush cylinder 52 has fluff. When the shaft ring 5 is located inside the lens barrel, by holding the handle 3 and rotating it clockwise, the screw shaft 2 is spirally raised inside the housing 1, driving the shaft ring 5 to move up, and the shaft ring 5 slowly rises with the rotation of the screw shaft 2, and finally reaches the opening of the lens barrel;

[0027] The brush cylinder 52 on the outer ring of the shaft ring 5 rotates on the cylinder to clean the inner wall of the lens barrel. When the shaft ring 5 rises, the lens barrel is evenly cleaned so that the inside of the lens barrel is completely cleaned. When the screw shaft 2 rotates, it drives the clamping strip 6 to rotate together. The cleaning cylinder 7 on the outer ring of the clamping strip 6 makes a circular motion along the bottom of the lens barrel, and the cleaning cylinder 7 itself makes a circular motion around the clamping strip 6 to completely clean the bottom of the lens barrel. The length of the cleaning cylinder 7 can be adjusted according to the size of the user's lens barrel.

[0028] Working principle: insert the shaft ring 5 into the lens barrel, tighten the internal thread 121 and the thread at the top opening of the lens barrel to fix the device on the lens barrel, use the hand to tighten the handle 3, drive the screw shaft 2 to rotate clockwise, drive the screw shaft 2 to make a circular motion, the shaft ring 5 is fixed at the bottom of the screw shaft 2, and the shaft ring 5 and the screw shaft 2 make a circular motion together. When the handle 3 drives the screw shaft 2 to rise in the inner circle 13, the inner wall of the lens barrel is cleaned by the shaft ring 5, and it rises slowly with the screw shaft 2 until it rises above the opening of the lens barrel. While the screw shaft 2 rotates, the brush barrel 52 on the outer ring of the shaft ring 5 fits tightly with the inner wall of the lens barrel, and the brush barrel 52 makes a circular motion along the cylinder to clean the inner wall of the lens barrel. The brush barrel 52 spirally cleans the inner wall of the lens barrel to avoid wear on the inner wall of the lens barrel caused by cleaning at a single position, and also achieves a uniform cleaning effect.

[0029] When a single lens barrel is cleaned, when the handle 3 is turned counterclockwise, the pawl 134 is stuck between the teeth, so that the screw shaft 2 cannot rotate counterclockwise. The shaft ring 5 is removed and replaced with a new shaft ring 5, and the pressing column 137 is pressed to make the pawl 134 disengage from between the teeth to release the restriction on the screw shaft 2. At this time, the handle 3 can be turned to make the screw shaft 2 rotate in the opposite direction and adjusted to a length that is connected to the inside of the lens barrel.
