Embodiment 1

[0041] This embodiment provides an endoscope self-locking device, including a housing and a rotating handle 10, the rotating handle 10 is connected to the housing, and the rotating handle 10 rotates relative to the housing;

[0042] Described rotating handle 10 comprises toggle support 11, left support 12, right support 13 and rotating shaft 14, and described toggle support 11 is fixedly connected with left support 12 and right support 13 respectively, and described left support 12 and right support 13 all connecting the rotating shaft 14, the rotating shaft 14 passes through the housing;

[0043] A locking member 20 is fixedly arranged in the housing, and the locking member 20 is rotatably connected to the rotating shaft 14, and the rotating shaft 14 is movably connected with a locking mechanism 30 for cooperating with the locking member 20;

[0044] The locking mechanism 30 includes a base 31, a push rod 32 and a locking member 2 33, the housing is fixedly connected to the b...

Embodiment 2

[0049] On the basis of Embodiment 1, preferably, the first locking member 20 and the second locking member 33 are engaged through a toothed structure.

[0050]Preferably, both the first locking member 20 and the second locking member 33 are toothed disc structures.

[0051] The teeth of the chainring mesh together and have a larger contact surface, which can achieve a better locking effect.

[0052] The cooperating mode of locking part 1 20 and locking part 2 33 is not limited to tooth structure meshing, other can make locking part 1 20 and locking part 2 33 cooperate, the structure that reaches the purpose of locking all can; A groove is provided on the locking piece 1 20, the outer diameter of the locking piece 2 33 is adapted to the groove, and the locking piece 2 33 falls into the groove, which can also achieve the purpose of the present invention.

Embodiment 3

[0054] On the basis of Embodiment 1 or 2, preferably, the second locking member 33 is provided with a connection block 331, and a connection groove 332 is provided on the connection block 331 along the axial direction of the rotating shaft 14, and the connection block 331 is connected by The slot 332 is slidably connected to the rotating shaft 14 .

[0055] It should be noted that two connecting shafts can be arranged on the rotating shaft 14, and the connecting shafts are connected in the connecting groove 332, and the connecting groove 332 can move relative to the connecting shafts; , so that the connecting groove 332 is relatively fixed to the connecting shaft.

[0056] During use, the push rod 32 pushes the locking part 2 33 to move and cooperate with the locking part 1 20. At this time, the end of the connecting groove 332 away from the locking part 20 slides to the position closest to the locking part 20, and connects with the locking part 1 20. Cooperate with the shaft...

Abstract

The invention relates to the technical field of endoscopes, in particular to an endoscope self-locking device and an endoscope. The self-locking device comprises a shell and a rotating handle, a firstlocking piece is fixedly arranged in the shell, a rotating shaft is rotatably connected in the first locking piece, and a locking mechanism used for being matched with the first locking piece is movably connected to the rotating shaft; the locking mechanism comprises a base, a push rod and a second locking piece, the base is fixedly connected to the shell, the interior of the base is connected tothe push rod through a thread, the push rod penetrates through the base and the shell, the push rod is used for pushing the second locking piece, the second locking piece is movably connected to therotating shaft, and the second locking piece moves in the axial direction of the rotating shaft; and the push rod controls the second locking piece to be matched with the first locking piece to realize self-locking. Self-locking can be achieved by the rotating handle, locking of an insertion tube is achieved, the imaging stability of the insertion tube is guaranteed, and meanwhile the fatigue strength of an operator is reduced.

Description

technical field [0001] The invention relates to the technical field of endoscopes, in particular to an endoscope self-locking device and an endoscope. Background technique [0002] In endoscope products, the bending and turning of the end of the insertion tube is realized by turning the turning handle, but the bending and turning of the insertion tube has a certain resilience. When the user does not apply force to the turning handle during operation, the insertion tube will rebound and deform. ;When observing at a certain angle inside the human body, because the insertion tube should be bent and rotated to keep it at a specific position, the user needs to apply force to the rotating handle all the time; but the user always applies force to control the insertion tube to maintain a specific position , will cause user fatigue, and the stability of the control is poor, so a self-locking structure needs to be provided to keep the insertion tube at a specific position.
