DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] Reference Figure 1-4 This is an embodiment of the utility model, which discloses a transparent cover structure of an abortion suction tube, the transparent cover structure includes a bracket 2 for connecting a tube body 1, a lens module 3 is placed inside the bracket 2, and the lens module 3 is fixed in the bracket 2 for realizing image acquisition. The specific structure and connection method have been disclosed in the prior art and will not be described in detail here;

[0024] A cover body 4 is provided at the front side of the bracket 2, and two connecting parts 21 are provided at the front end of the bracket 2. The two connecting parts 21 are distributed circumferentially and are adapted to the inner hole of the cover body 4;

[0025] A locking structure 5 is further provided between the cover body 4 and the connecting portion 21 , and a sealing member 6 for fitting with the cover body 4 is provided on the front side of the bracket 2 .

[0026] In some embodiments, the locking structure 5 in the utility model includes a guide groove 51 opened on the connecting portion 21, one end of the guide groove 51 extends to the side of the connecting portion 21, and a slider 52 that slides to the guide groove 51 is fixedly installed on the inner side of the bracket 2. When connecting, first align the two sliders 52 of the cover body 4 between the two connecting portions 21, and then rotate the cover body 4 to make the slider 52 snap into the guide groove 51 to achieve the connection of the cover body 4.

[0027] On the basis of the above embodiment, the guide groove 51 in this embodiment includes an entrance groove 511, a direction-changing groove 512 connected to the end of the entrance groove 511, and a tensioning groove 513 connected to the end of the direction-changing groove 512;

[0028] Among them, the tensioning groove 513 is close to one side of the connecting part 21, and an open mouth 514 is provided at the end of the entrance groove 511. The design of the open mouth 514 facilitates the sliding block 52 to slide into the interior of the entrance groove 511. In this embodiment, a Z-shaped structure is jointly constructed between the entrance groove 511, the changing groove 512 and the tensioning groove 513. During the specific connection, when the sliding block 52 enters the tensioning groove 513 along the entrance groove 511 and the changing groove 512, the cover body 4 will move a small distance toward one side of the connecting part 21, and realize the connection seal by squeezing the sealing member 6.

[0029] Of course, the locking of the position of the slider 52 must also be considered. Therefore, in this embodiment, a locking component 53 is also provided at the inner tail end of the guide groove 51. The locking component 53 is used to lock the position of the slider 52. Specifically, the locking component 53 described in this embodiment is arranged inside the tensioning groove 513.

[0030] In more detail, the locking component 53 in this embodiment includes a placement groove provided inside the guide groove 51, in which an elastic sheet 531 is fixed, and a protrusion 532 is fixedly installed on the elastic sheet 531, and the protrusion 532 is arranged as a wedge structure. When the slider 52 rotates and moves along the tensioning groove 513, the elastic sheet 531 is driven to move after contacting the protrusion 532 until the protrusion 532 is engaged with the other side of the slider 52 to realize position positioning. Furthermore, when it is necessary to remove the above-mentioned cover body 4, the cover body 4 is pushed inward with force to further squeeze the sealing member 6 by a small distance. In this way, when the side of the slider 52 is misaligned with the protrusion 532, the cover body 4 can be rotated in the opposite direction to remove it. That is to say, the width of the guide groove 51 in this embodiment is greater than the thickness of the slider 52 to provide a small distance pushing displacement space.

[0031] In some embodiments, the front end of the bracket 2 of the present invention is provided with an annular groove, and the sealing member 6 is a sealing ring embedded in the annular groove.

[0032] In summary, the utility model realizes the function of quick disassembly and assembly through the innovative design of the cover body 4 and the bracket 2. The design fully considers the convenience in actual operation, so that the cover body 4 can be easily removed for replacement and thorough cleaning. In addition, this structural design also facilitates the rapid inspection and maintenance of the internal precision lens module 3;

[0033] Structurally, the connection mechanism between the cover body 4 and the connection part 21 is simple and efficient. When disassembly or assembly is required, the operator only needs to gently rotate the cover body 4 along the connection part 21 and use the guide groove 51 for precise alignment and traction to quickly complete the connection or separation. This process does not require the use of special tools, simplifies the operation process, and enhances the applicability of the product.

[0034] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
