In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, but the present invention may be implemented in other ways different from the specific details set forth herein, and one skilled in the art may similarly generalize the present invention without departing from the spirit of the present invention, and therefore the present invention is not limited to the specific embodiments disclosed below.

Furthermore, the references herein to "one embodiment" or "an embodiment" refer to a particular feature, structure, or characteristic that may be included in at least one implementation of the invention. The appearances of the phrase "in one embodiment" in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments.

Referring to fig. 1 to 5, the self-locking device of the endoscope according to the first embodiment of the present invention includes the endoscope, which includes a housing 100 and a toggle member 200, wherein the toggle member 200 is disposed outside the housing 100 and performs a relative rotation motion.

And a housing 100 provided outside the endoscope, having a hollow interior, and an internal structure of the endoscope and some plug wires are provided inside the housing 100.

The toggle member 200 comprises a toggle support 201, an elastic support 202 and a toggle 203, the toggle 203 is sleeved on the toggle support 201 and moves along the sleeved direction, the shaft of the toggle support 201 passes through the shell 100, and the other side of the toggle support is connected with the elastic support 202. That is, the handle 203 is sleeved on the toggle frame 201, but can move left and right along the toggle frame 201.

The inner side of the toggle support 201 is provided with a toggle rod 201a and a friction plate 201b, the cross section of the toggle rod 201a is L-shaped, the middle bending part of the toggle rod 201a is fixed with the toggle support 201, the toggle rod 201a is hinged with the toggle support 201 through a first pin bolt 301, and after the toggle rod 201a is stressed, the toggle rod 201a can rotate relative to the first pin bolt 301 to push the friction plate 201b to move.

It should be noted that the shift lever 201a is hinged to the shift handle 203 through a second pin 302, a hole of the connection end of the shift lever 201a is an oblong hole, and the shift handle 203 penetrates through the oblong hole to be matched with the shift bracket 201. Therefore, when the handle 203 moves on the toggle bracket 201, the toggle 201a with the oblong hole can move up and down, left and right (herein, left and right refers to a direction perpendicular to the toggle bracket 201) around the second pin 302.

It should be noted that, in the present embodiment, there is no connection relationship between the friction plate 201b and the shift lever 201 a.

Preferably, one end of the shift lever 201a is provided with a matching protrusion 201a-1, one end of the friction plate 201b is provided with an embedding protrusion 201b-1, and the surface of the matching protrusion 201a-1 is opposite to the surface of the embedding protrusion 201b-1, and the two are matched with each other.

Preferably, the fitting projection 201a-1 and the fitting projection 201b-1 are both smoothly curved surfaces. For example, the cross-sections of the fitting projection 201a-1 and the fitting projection 201b-1 are semicircular.

Preferably, the number of the engaging protrusions 201a-1 is the same as that of the engaging protrusions 201 b-1.

The self-locking device of the endoscope of the utility model has the working principle that: if in the initial state, the toggle handle 203 is arranged on the left side of the toggle bracket 201. The dial 203 is manually dialed so that it moves from the left side of the dial support 201 to the right side of the dial support 201 and to the right side of the dial support 201. In the process that the dial 203 moves from the left side of the dial bracket 201 to the right side of the dial bracket 201, after one end of the oblong hole of the dial 201a and the second pin bolt 302 move relatively, the dial 201a rotates at the position of the first pin bolt 301. If the initial position is as shown in the figure, the engaging protrusion 201a-1 is disposed below the engaging protrusion 201b-1, and after the driving lever 201a rotates at the position of the first pin 301, the engaging protrusion 201a-1 is disposed above the engaging protrusion 201 b-1.

Referring to fig. 1 to 5, a self-locking device for an endoscope according to a second embodiment of the present invention is different from the first embodiment in that: in this embodiment, one end of the friction plate 201b is fixed to the other end of the elastic support 202 through the long shaft 303.

Specifically, in this embodiment, the main body of the self-locking device of the endoscope includes the endoscope, the endoscope includes a housing 100 and a toggle member 200, and the toggle member 200 is outside the housing 100 and performs relative rotational movement.

It should be noted that one end of the friction plate 201b is fixed to the other end of the elastic support 202 through the long shaft 303. In the whole movement process, under the initial state, the elastic support 202 is in contact with the shell 100, so that the resistance of the movement of poking the tail end of the plug wire through the poking piece 200 becomes very large, the tail end of the plug wire is in a self-locking state under the effect of no external force, and the poking piece 200 is difficult to poke. When the matching lug 201a-1 moves from the lower part of the embedding lug 201b-1 to the upper part of the embedding lug 201b-1, the friction plate 201b pushes the long shaft 303, so that the elastic support 202 is not contacted with the shell 100, and the resistance of the movement of shifting the tail end of the plug wire through the shifting piece 200 becomes small, so that the tail end of the plug wire can freely move through the shifting piece 200 and be shifted for one time.

Referring to fig. 1 to 7, in another embodiment of the self-locking device of the endoscope of the present invention, the friction plate 201b of the embodiment includes a first gear 201b-2, a second gear 201b-3, a rubber sheet 201b-4, a nut 201b-5, and a bolt 201b-6, and the toggle frame 201, the second gear 201b-3, and the rubber sheet 201b-4 are passed through the bolt 201b-6 and fixed at the other end by the nut 201 b-5.

In the embodiment, a spring is provided between the first gear 201b-2 and the second gear 201b-3, so that the first gear 201b-2 and the second gear 201b-3 can be reset without being subjected to an external force.

The fitting projection 201b-1 is provided on the first gear 201 b-2.

The working principle in this embodiment is as follows: if in the initial state, the toggle handle 203 is arranged on the left side of the toggle bracket 201. When the manual toggle handle 203 moves, the manual toggle handle moves from the left side of the toggle bracket 201 to the right side of the toggle bracket 201 and moves to the right side of the toggle bracket 201. In the process that the dial 203 moves from the left side of the dial bracket 201 to the right side of the dial bracket 201, after one end of the oblong hole of the dial 201a and the second pin bolt 302 move relatively, the dial 201a rotates at the position of the first pin bolt 301. If the initial position is as shown in the figure, the engaging protrusion 201a-1 is disposed below the engaging protrusion 201b-1, and after the driving lever 201a rotates at the position of the first pin 301, the engaging protrusion 201a-1 is disposed above the engaging protrusion 201 b-1. At this time, the first gear 201b-2 and the second gear 201b-3 are engaged, and the tightness is adjusted by adjusting the gap between the nut 201b-5 and the housing 100.

In the whole movement process, in the initial state, the first gear 201b-2 is meshed with the second gear 201b-3, the adjusting nut 201b-5 is tightly contacted with the shell 100, so that the resistance of the movement of poking the tail end of the plug wire through the poking piece 200 is large, the tail end of the plug wire is in a self-locking state without the action of external force, and the poking piece 200 is difficult to poke. When the contact between the adjusting nut 201b-5 and the housing 100 is loose, the resistance of the movement of poking the tail end of the plug wire through the poking part 200 becomes smaller, and the poking part 200 pokes better.
