Fig. 7 is a schematic view of a first embodiment tip seal assembly of the present disclosure. As shown in fig. 7, the tip seal assembly includes: a sealing sleeve 108, a protective window 109 and an eye cup 110. The material of the protection window 109 is sapphire. The protection window 109 and the sealing sleeve 108 are fixed by soldering, and during soldering, solder is ensured to fill the gap between the protection window 109 and the sealing sleeve 108, so that the gap between the protection window 109 and the sealing sleeve 108 is airtight after soldering. The eye cup 110 is adhesively secured to the second end of the sealing sleeve 108. Referring to FIG. 1, the first end of the sealing sleeve 108 is secured to the body 106 of the outer tube assembly 03 by laser welding at a weld location C as shown.
In a second exemplary embodiment of the present disclosure, a hard tube endoscope is provided. Compared with the rigid tube endoscope of the first embodiment, the rigid tube endoscope of the present embodiment is different in that: a second sealing window seat 112 is additionally provided in the tip seal assembly 04. Fig. 8 is a schematic view of a second embodiment tip seal assembly of the present disclosure. As shown in fig. 8, a second sealing window seat 112 is used to connect the sealing sleeve 108 and the protection window 109. The first end of the second sealing window seat 112 is embedded in the second end of the sealing sleeve 108, and the second end of the second sealing window seat 112 is fixedly connected with the protection window 109 through brazing. In the assembly process of the end seal assembly 04, it is usually necessary to clean the inside surface of the brazed protection window 109, in which the protection window 109 is brazed to the second sealing window seat 112, and then the second sealing window seat 112 is brazed to the end face of the sealing sleeve 108, so as to make the inside surface of the brazed protection window 109 easier to clean.
In a third exemplary embodiment of the present disclosure, a hard tube endoscope is provided. Compared with the rigid tube endoscope of the first embodiment, the tip assembly 01 of the present embodiment is different in that: the structure of the sealing head 103 is improved, and the limit ring 102 is not arranged. Fig. 9 is a schematic view of a third embodiment of a header assembly according to the present disclosure. As shown in fig. 9, the head assembly 01 includes: a sealing window 101 and a sealing head 103. The sealing window 101 is embedded in the sealing head 103, and the second end of the sealing head 103 is fixedly connected with the middle pipe 104 through laser welding. The included angle between the aperture of the sealing head 103 and the circumference of the middle tube 104 is used as a hard tube endoscope with viewing angles of 0 degree, 12 degrees, 25 degrees and 30 degrees.
Wherein, the coaxial setting of sealing head 103 includes: a first bore and a second bore. First hole first end sets up at sealed first end, and first hole second end is connected with the first end of second hole and is constituted spacing platform, and second hole second end extends to sealed first 103 second ends. The outer diameter of the sealing window 101 is larger than the inner diameter of the second inner hole, and the outer diameter of the sealing window 101 is not larger than the inner diameter of the first inner hole, so that the sealing window 101 can be abutted to the limiting table.
In the embodiment, the axial size of the sealing head 103 is reduced on the premise that the distance between the end surface of the sealing window 101 and the end surface of the sealing head 103 is ensured to be about 0.2 mm. As shown in fig. 9, the welding position a of the sealing head 103 and the middle tube 104 of the tip assembly 01 needs to be controlled strictly for welding speed, so as to prevent the base material temperature from being higher than the brazing temperature of the sapphire material of the sealing window 101, and at the same time, the coaxiality of the sealing head 103 and the middle tube 104 needs to be controlled strictly.
In a fourth exemplary embodiment of the present disclosure, a hard tube endoscope is provided. Compared with the hard tube endoscope of the first embodiment, the tip assembly 01 of the present embodiment is different in that: the spacing ring 102 and the sealing head 103 are integrally formed. Fig. 10 is a schematic view of a fourth embodiment of a header assembly according to the present disclosure. This embodiment is applied to a rigid tube endoscope having a viewing angle of 0 ° as shown in fig. 10, and can save the processing cost and further improve the waterproof reliability of the tip assembly 01.
In a fifth exemplary embodiment of the present disclosure, a hard tube endoscope is provided. Compared with the rigid tube endoscope of the first embodiment, the tip assembly 01 of the present embodiment is different in that: the head assembly 01 includes: a sealing window 101, a sealing head 103 and a first sealing window seat 111. As shown in FIG. 11, in this embodiment, the sealing head 103 is not a linear shaft structure, but an L-shaped shaft structure (the first end axis of the sealing head 103 is perpendicular to the second end axis) is adopted to be suitable for a hard tube endoscope with a viewing angle of 70 degrees. Specifically, sealing window 101 and first sealing window seat 111 pass through brazing fixed connection, and sealing head 103 first end and first sealing window seat 111 pass through laser welding fixed connection, and sealing head 103 second end links to each other with well pipe 104 first end is coaxial to pass through laser welding fixed connection.
