Technical Field

[0001] The present invention relates to the field of nose mirrors, and in particular to an electronic nose mirror capable of quickly adjusting and replacing the diameter of a tube body. Background Art

[0002] Electronic rhinoscopy is a type of endoscope used to examine and treat lesions in the nasopharynx. Because the nasopharynx is hidden deep behind the nasal cavity and cannot be seen under normal circumstances, electronic rhinoscopy allows examination of the nasopharynx through the nasal cavity under nasal anesthesia. This is convenient, pain-free, and provides a clear and intuitive view.

DETAILED DESCRIPTION

[0025] In order to clearly and completely describe the objectives and technical solutions of the present invention and make the advantages more clearly understood, the embodiments of the present invention are further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are part of the embodiments of the present invention, rather than all of the embodiments, and are only used to explain the embodiments of the present invention and are not intended to limit the embodiments of the present invention. All other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] See also Figure 1-Figure 7The present invention provides a technical solution: an electronic nose mirror with a tube diameter that can be quickly adjusted and replaced, comprising a hose 1, a lens tube 2, a lens 3, a wire 4 and a lock cylinder 7. The upper end of the lens tube 2 is provided with a lock cylinder groove 5, and the inner wall of the lock cylinder groove 5 is symmetrically provided with a lock block groove 6. The lock cylinder 7 is plug-in installed on the upper end of the lens tube 2 through the lock cylinder groove 5. The bottom of the hose 1 is sleeved on the lock cylinder 7 and is in airtight contact with the upper end surface of the lens tube 2. The lens 3 is installed at the bottom of the lens tube 2, and the wire 4 is installed on the lens 3. The wire 4 passes through the lens 3, the lock cylinder 7 and the hose 1 and is connected to the host. A lock block 11 is symmetrically plug-in installed on the lower part of the lock cylinder 7. The end of the lock block 11 is trapezoidal, and an ear block 12 is installed on the upper surface of the end of the lock block 11. The side wall of the ear block 12 is provided with a reset spring 13. When the lock block 11 is pushed back under the action of the return spring 13, the guide bar 112 fits with the end of the slide 111 away from the extrusion seat 10, thus limiting the movement range of the lock block 11 and ensuring the stable cooperation of the lock block 11 and other components.

[0027] The ejector rod assembly includes a cylindrical seat 8, an ejector rod 9, an extrusion seat 10, a push spring 14, a cylindrical seat 15 and an annular groove 16. The cylindrical seat 8 is installed on the upper end of the lock cylinder 7 by screws, and the ejector rod 9 is plug-in installed in the cylindrical seat 8. The lower part of the ejector rod 9 is installed with an extrusion seat 10. The bottom surface of the extrusion seat 10 is fixed with a push spring 14. The lower part of the push spring 14 is placed in the annular groove 16. The annular groove 16 is opened on the cylindrical seat 15, and the cylindrical seat 15 is installed at the bottom of the lock cylinder 7. In the initial state, the pushing spring 14 is in a compressed state, pressing against the extrusion seat 10, and the extrusion seat 10 pushes the locking block 11 to stretch the reset spring 13. At the same time, the locking block 11 is placed in the locking block groove 6, so that the lens tube 2 and the lock cylinder body 7 are in a fixed connection state. During disassembly, the extrusion seat 10 is pressed down by the lock cylinder body 7, so that the locking block groove 6 is pushed back to the initial position under the action of the reset spring 13 and disengaged from the locking block groove 6, so that it is convenient to push the lock cylinder body 7 out of the way, and it is convenient to disassemble, replace, and repair the lens tube 2 and the lens 3.

[0028] A guide groove 17 is provided at the upper end of the cylindrical seat 8, and a guide ring 18 is slidably installed in the guide groove 17, and when the extrusion seat 10 drops to the lowest position, the bottom surface of the guide ring 18 fits with the bottom surface of the guide groove 17, thus limiting the maximum descending size of the extrusion seat 10, and the side walls of the guide ring 18 are symmetrically installed with limit blocks 20, which are plug-in installed in the limit groove 22, and the limit groove 22 is symmetrically opened on the inner wall of the guide groove 17, and the depth of the limit groove 22 is equal to the depth of the guide groove 17. The limit groove 22 and the limit block 20 can prevent the push rod 9 from rotating during the lifting process, and the side wall of the limit block 20 is symmetrically provided with a roller groove, and the roller groove is rotatably installed with a roller 21, and the rolling surface of the roller 21 contacts the inner wall of the limit groove 22, and the friction between the limit block 20 and the limit groove 22 can be reduced by the roller 21.

[0029] The side wall of the guide ring 18 is provided with a locking rod groove 19, which is a rectangular groove structure, and the guide ring 18 is fixed by a locking assembly, which includes a rectangular groove 23, a locking rod 24, a limit plate 25 and a spring 26. The rectangular groove 23 is provided on the end face of the cylindrical seat 8, and a locking rod 24 is installed in the rectangular groove 23 in an insert-type manner. The end of the locking rod 24 passes through the side wall of the cylindrical seat 8 and is inserted into the locking rod groove 19. A limit plate 25 is installed on the locking rod 24, and a spring 26 is provided on one side of the limit plate 25. The spring 26 is sleeved on the locking rod 24. After the ejector rod 9 is used, in order to avoid accidental touch, the ejector rod 9 drops again, causing the lock block groove 6 to be locked. When in use, it is convenient to push the top plate 29 into the top plate groove 30, so that the locking rod 24 releases the fixation of the guide ring 18, which facilitates the lifting and lowering of the ejector rod 9 and the guide ring 18.
