Description

Technical Field

[0001] The utility model relates to the technical field of electronic endoscopes, in particular to an electronic endoscope water bottle joint locking seat, a positioning sleeve, a water bottle joint, a light guide part and an electronic endoscope. Background Art

[0002] The existing electronic endoscope water bottle connector and the water and gas three-way welding assembly are connected by threads. During installation, the water bottle connector is tightened and assembled on the light guide housing using a set torque using a tool. However, due to the difference in the screw-in points of the water bottle connector and the water and gas three-way welding assembly, as well as the size differences of the other mating parts, the position of the locating pin of the water bottle connector is highly random after being tightened. When the user holds the water and gas bottle valve locking cover and connects it with the locating pin of the water bottle connector through its card slot, the operator's action is inconsistent each time the connection is made due to the difference in the orientation of the locating pin (all angles along the circumferential direction are possible), which brings inconvenience to operation.

[0003] Therefore, those skilled in the art are committed to developing an electronic endoscope water bottle connector locking seat, a positioning sleeve, a water bottle connector, a light guide portion and an electronic endoscope, so that the positioning pin position remains consistent after the water bottle connector is assembled.

[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, in the description of the present invention, the terms "upper," "lower," "left," "right," "inner," "outer," and the like, indicating directions or positions, are based on the directions or positions shown in the accompanying drawings and are intended solely for the purpose of facilitating and simplifying the description of the present invention. They are not intended to indicate or imply that the devices or components referred to must have a specific direction, be constructed, or operate in a specific manner. Therefore, they should not be construed as limiting the present invention. The terms "first," "second," and "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0025] like Figure 1-3 As shown, an electronic endoscope water bottle connector locking seat includes a connector 1, a first locking step 1a is provided on the outer wall of the connector 1, and an assembly tooling process notch 1b is opened on the top of the connector 1 to facilitate installation using tooling.

[0026] like Figure 1 、 2 As shown in Figure 4, the utility model also provides an electronic endoscope water bottle joint positioning sleeve, including a bushing 2, which is a hollow cylindrical shape. A radially extending second locking step 2a is provided at the bottom of the inner wall of the bushing 2, and a radially extending positioning pin 2b is provided on the outer wall of the bushing 2. The positioning pin 2b facilitates docking with other components. A radially extending pressure ring 2c is provided on the outer wall of the bottom of the bushing 2, and a positioning boss 2d is provided at the bottom of the pressure ring 2c. The positioning boss 2d extends axially along the bushing 2.

[0027] like Figure 1-4 As shown, the utility model also provides an electronic endoscope water bottle connector, including a water bottle connector locking seat as described above and a water bottle connector positioning sleeve as described above, the bushing 2 is slidably matched with the connector 1. In this embodiment, the sliding fit is a clearance fit, the bushing 2 is sleeved on the outside of the connector 1, and the connector 1 can rotate independently relative to the bushing 2. The outer diameter of the connector 1 is slightly smaller than the inner diameter of the bushing 2, the outer diameter of the first locking step 1a is larger than the inner diameter of the second locking step 2a, and the first locking step 1a and the second locking step 2a are clamped with each other.

[0028] like Figure 5 As shown, the present invention further provides a light guide portion of an electronic endoscope, comprising a housing 3 , on which a positioning groove 3 a is provided.

[0029] like Figure 6-9As shown, the utility model also provides an electronic endoscope, including the electronic endoscope water bottle connector and the electronic endoscope light guide as described above, and also including a water-gas tee welding assembly 4, the water-gas tee welding assembly 4 is threadedly connected to the connector 1, and a sealing gasket 3b is provided on the outer shell 3, the sealing gasket 3b is located below the pressure ring 2c, the sealing gasket 3b coincides with the axis of the pressure ring 2c, and the outer diameter of the sealing gasket 3b is less than or equal to the outer diameter of the pressure ring 2c.

[0030] During use, first align the positioning boss 2d on the bushing 2 with the positioning groove 3a on the housing and press it down, then connect the connector 1 to the water-gas tee welding assembly 4. As the connector 1 and the water-gas tee welding assembly 4 are gradually tightened, the first locking step 1a abuts against the second locking step 2a, driving the second locking step 2a to move. The second locking step 2a drives the bushing 2 to move synchronously, and while the bushing 2 moves downward, it drives the pressure ring 2c to press the sealing gasket 3b, thereby improving the overall airtightness of the equipment. In addition, due to the arrangement of the positioning boss 2d and the positioning groove 3a, the bushing 2 will not rotate synchronously with the connector 1 during the tightening process of the connector 1, so that no matter how the connector 1 rotates, the positioning pin 2b on the bushing 2 can ensure the consistency of direction.

[0031] The above describes in detail the preferred embodiments of the present invention. It should be understood that those skilled in the art can make numerous modifications and variations based on the concepts of the present invention without inventive effort. Therefore, any technical solutions that can be derived by those skilled in the art based on the concepts of the present invention through logical analysis, reasoning, or limited experimentation based on the existing technology should be within the scope of protection defined by the claims.
