[0043] like Figure 2 、 Figure 5 、 Figure 6 and Figure 7 As shown, the present application provides an endoscope stop device, which includes:

[0044] Housing shaft assembly 100;

[0045] The roller 200 is provided with a shaft hole 210 and a lock hole 220 connected thereto;

[0046] The locking assembly 300 extends to the communication area between the shaft hole 210 and the locking hole 220 and is engaged with the housing shaft assembly 100 .

[0047] In the present application, a locking hole 220 connected to the axial hole 210 of the roller 200 is provided on the roller 200, and the locking hole 220 can be provided at the outer ring surface of the roller 200. At the same time, a locking assembly 300 is provided, and the locking assembly 300 extends through the locking hole 220 to the connecting area between the axial hole 210 and the locking hole 220, and is engaged with the shell shaft assembly 100 at the connecting area. Then, during the rotation of the roller 200, the roller 200 can be stopped immediately, thereby avoiding the loss of the target, improving the operating efficiency of the endoscope, and greatly improving the user experience.

[0048] In some embodiments, as Figure 3 and Figure 4As shown, the locking assembly 300 includes an elastic member 310 and a pressing member 320, and the locking hole 220 includes a first locking hole 221 and a second locking hole 222 arranged opposite to each other; wherein, the elastic member 310 is arranged in the first locking hole 221, one end of the elastic member 310 is clamped with the shell shaft assembly 100, and the other end of the elastic member 310 is clamped with the roller 200; the pressing member 320 extends from the second locking hole 222 to one end of the elastic member 310, and is clamped with one end of the elastic member 310.

[0049] In the present application, the locking hole 220 can be composed of a first locking hole 221 and a second locking hole 222. The first locking hole 221 and the second locking hole 222 can both be arranged on the outer annular surface of the roller 200 and arranged relative to each other. At the same time, the first locking hole 221 and the second locking hole 222 can both be connected to the shaft hole 210, that is, the first locking hole 221 and the second locking hole 222 both extend from the outer annular surface of the roller 200 to the center of the roller 200 to be connected to the shaft hole 210 of the roller 200.

[0050] Specifically, the locking assembly 300 can be composed of an elastic member 310 and a pressing member 320. The elastic member 310 can be arranged in the first locking hole 221. One end of the elastic member 310 is in the connecting area and is clamped with the shell shaft assembly 100, and the other end of the elastic member 310 is in contact with or clamped with the roller 200 in the first locking hole 221. At the same time, one end of the pressing member 320 extends to one end of the elastic member 310 through the second locking hole 222 and abuts against one end of the elastic member 310. At the same time, the other end of the pressing member 320 is arranged on the outside of the roller 200. The operator can press the other end of the pressing member 320 to make one end of the elastic member 310 disengage from the shell shaft assembly 100. At this time, the roller 200 can rotate. If the operator stops pressing the pressing member 320, the elastic member 310 will be engaged with the shell shaft assembly 100, and the roller 200 can stop rotating. The roller 200 is stopped immediately to prevent the operator from losing the previously aligned target, thereby improving the operating efficiency of the endoscope and greatly improving the user experience.

[0051] In some embodiments, as Figure 3 、 Figure 4 、 Figure 8 and Figure 9 As shown, the elastic member 310 includes a base 311, a spring 312 and a leaf spring seat 313; wherein, one end of the spring 312 abuts against the base 311, and the other end of the spring 312 abuts against the leaf spring seat 313; the leaf spring seat 313 is clamped with the housing shaft assembly 100, and the base 311 is clamped with the roller 200.

[0052] In the present application, the elastic member 310 can be composed of a base 311, a spring 312 and a leaf spring seat 313. The spring 312 can be arranged in the first locking hole 221. One end of the base 311 extends into the first locking hole 221 and abuts against one end of the spring 312. At the same time, one end of the base 311 can be provided with a accommodating cavity. One end of the spring 312 is arranged in the accommodating cavity and abuts against the base 311. At the same time, the base 311 can be clamped with the roller 200 in the first locking hole 221, so that one end of the spring 312 can abut against the roller 200.

[0053] Specifically, the other end of the spring 312 can abut against the leaf spring seat 313 provided in the first lock hole 221. At the same time, the leaf spring seat 313 can be engaged with the housing shaft assembly 100 and abut against one end of the pressing member 320. Then, the operator can press the other end of the pressing member 320 to disengage the leaf spring seat 313 from the housing shaft assembly 100. At this time, the roller 200 can rotate. If the operator stops pressing the pressing member 320, the leaf spring seat 313 will be engaged with the housing shaft assembly 100, and the roller 200 can stop rotating. The roller 200 is immediately stopped, preventing the operator from losing the previously aligned target, improving the operating efficiency of the endoscope, and greatly improving the user experience. Among them, a hole groove 3131 can be provided at the contact area between the leaf spring seat 313 and the spring 312 to achieve abutment with the spring 312 in the hole groove 3131.

[0054] Furthermore, in some embodiments, Figure 3 、 Figure 4 、 Figure 8 and Figure 9 As shown, the base 311 extends from the first locking hole 221 to one end of the spring 312 and abuts against one end of the spring 312 .

The first protrusion 3111 is engaged in the first slot 230 to engage the base 311 with the roller 200 .

[0056] In the present application, the snap-fitting between the first protrusion 3111 and the first slot 230 can ensure a stable connection between the base 311 and the roller 200, avoiding connection failure due to vibration or impact, improving the stability and reliability of the connection, and simplifying the installation and maintenance process, which has significant advantages.

[0057] In some embodiments, as Figure 2 、 Figure 3 and Figure 4As shown, the instant stop device further includes a rocker 330 , wherein the rocker 330 is sleeved on the pressing member 320 and extends into the second locking hole 222 to engage with the roller 200 .

[0058] In the present application, the rocker 330 is sleeved on the pressing member 320 and extends into the second locking hole 222 to engage with the roller 200. When the operator does not press the pressing member 320, the locking assembly 300 is engaged with the shell shaft assembly 100. If the rocker 330 is operated, the roller 200 cannot rotate; when the operator presses the pressing member 320, the locking assembly 300 is disengaged from the shell shaft assembly 100. At this time, the rocker 330 is operated to realize the rotation of the roller 200.

[0059] In some embodiments, as Figure 2 、 Figure 3 and Figure 7 As shown, at least one second protrusion 331 is provided at one end of the rocker 330 , and at least one second slot 240 is provided in the second locking hole 222 . The second protrusion 331 is engaged in the second slot 240 to engage the rocker 330 with the roller 200 .

[0060] In this application, the snap-fit ​​connection between the second protrusion 331 and the second slot 240 requires no complex tools or procedures. Installation is completed by simply inserting the second protrusion 331 into the second slot 240, significantly simplifying the installation process and improving work efficiency. Furthermore, this snap-fit ​​connection between the second protrusion 331 and the second slot 240 ensures a secure connection between the rocker 330 and the roller 200, preventing loosening or falling off during use. Furthermore, the second slot 240 extends through the roller 200, facilitating subsequent removal of the rocker 330 from the roller 200.

[0061] In some embodiments, as Figure 4 As shown, the housing shaft assembly 100 includes a first shaft 110 and a second shaft 120 arranged opposite to each other on both sides of the shaft hole 210; wherein, one end of the first shaft 110 is fixedly connected to the housing of the endoscope; the other end of the first shaft 110 extends into the shaft hole 210 and is engaged with the locking assembly 300; one end of the second shaft 120 is fixedly connected to the housing of the endoscope; the other end of the second shaft 120 extends into the shaft hole 210 and is engaged with the locking assembly 300.

[0062] In the present application, the housing shaft assembly 100 may be provided with a corresponding first housing shaft 130 and a second housing shaft 140. The first housing shaft 130 may be disposed within the shaft hole 210 of the roller 200 via the first shaft 110 and engaged with the locking assembly 300. The second housing shaft 140 may be disposed within the shaft hole 210 of the roller 200 via the second shaft 120 and engaged with the locking assembly 300, thereby achieving a locking connection between the housing and the roller 200. The first shaft 110 and the second housing shaft 140 may be integrally formed, and the second shaft 120 and the second housing shaft 140 may be integrally formed.

[0063] In some embodiments, as Figure 3 As shown, the first shaft 110 and the second shaft 120 both adopt a gear structure and are engaged with the locking assembly 300 .

[0064] In the present application, the gear structure includes external teeth and internal teeth. The external teeth are provided on the first shaft 110 and the second shaft 120, and the internal teeth are provided on the locking assembly 300. The present application adopts the gear structure to clamp the first shaft 110 and the second shaft 120 with the locking assembly 300 respectively, so that the roller 200 can be stopped immediately, which not only improves the stability and reliability of the connection, but also simplifies the installation and maintenance process, and has significant advantages.

[0065] In some embodiments, the present application also provides an endoscope, which includes the instant stop device of the endoscope provided by the present application.

[0066] The instant stop device of the endoscope and the endoscope provided in the present application include a shell shaft assembly 100, a roller 200 and a locking assembly 300. The roller 200 is provided with a connected shaft hole 210 and a locking hole 220.
