[0026] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0027] See also Figure 1-Figure 8The invention discloses a quickly disassembled endoscope pipeline structure, comprising a host socket 1 and a pipeline plug seat 2, wherein a socket cover 11 is provided at one end of the host socket 1, and a plurality of connecting holes 111 are provided on the socket cover 11, and a push plate 12 is provided inside the host socket 1, which is close to the inner side of the socket cover 11, and a shaft sleeve 121 adapted to each of the connecting holes 111 is extended from one side of the push plate 12, and a positioning mechanism is provided inside each of the shaft sleeves 121, and the host socket 1 A quick release button 13 is provided on the push plate 12 to drive the push plate 12 to move, and a limit hole 131 is provided on the quick release button 13. One end of the pipeline plug socket 2 is provided with a connector 21 adapted to the limit hole 131. Further, the host socket 1 and the socket cover 11 are both provided with openings at positions corresponding to the limit hole 131. A raised limit block 139 is provided in the limit hole 131, and a slot 211 adapted to the limit block 139 is provided on the connector 21. One end of the pipeline plug socket 2 is also provided with a pipeline traction rod 22 that can be sequentially embedded in the connection hole 111 and the shaft sleeve 121 and cooperate with the positioning mechanism. When the host socket 1 and the pipeline plug socket 2 are connected, the pipeline traction rod 22 is inserted into the host socket 1 facing the connection hole 111. At this time, the pipeline traction rod 22 is located in the shaft sleeve 121 and connected to the positioning mechanism, and the connecting member 21 is embedded in the limiting hole 131. On the contrary, when the host socket 1 and the pipeline plug socket 2 are separated, the quick release button 13 is pressed, and the quick release button 13 drives the push plate 12 to move downward. At this time, the positioning mechanism is separated from the pipeline traction rod 22, and the connecting member 21 is removed from the limiting hole 131, completing the rapid installation and disassembly between the host socket 1 and the pipeline plug socket 2. The host socket 1 is provided with a host traction guide wire 14 extending into the positioning mechanism, and the pipeline plug socket 2 is provided with a pipeline guide wire 221 connected to the pipeline traction rod 22.

[0028] Specifically, the positioning mechanism includes an annular release sleeve 15 disposed in the shaft sleeve 121, and the release sleeve 15 is fixedly connected to the shaft sleeve 121, that is, when the push plate 12 moves, the release sleeve 15 will move along. A fixing seat 16 is disposed inside the release sleeve 15, one end of the fixing seat 16 is fixedly connected to the host socket 1, and the other end extends into the release sleeve 15 and is fixedly connected to the socket cover 11. The fixing seat 16 is fixed inside the host socket 1. When the push plate 12 moves, the release sleeve 15 slides on the outer surface of the fixing seat 16. When the host socket 1 and the pipeline plug socket 2 are connected, the pipeline traction rod 22 can extend into the fixing seat 16, and the host traction guide wire 14 extends into the fixing seat 16, so that the host traction guide wire 14 and the pipeline guide wire 221 are accurately aligned, realizing the linkage between the host socket 1 and the pipeline plug socket 2. The fixing seat 16 is provided with a plurality of through holes 161, and the release sleeve 15 is provided with a release hole corresponding to the position of each through hole 161, and a retaining steel ball 17 is provided between the through hole 161 and the release hole, that is, the retaining steel ball 17 is provided between the release sleeve 15 and the fixing seat 16. Specifically, the release hole includes a shallow hole 151 and a deep hole 152 that are connected, and the deep hole 152 is provided at one end close to the push plate 12, and the shallow hole 151 is provided on the other side of the deep hole 152. The shallow hole 151 and the deep hole 152 are connected and cooperate with each other to form a step shape, and the retaining steel ball 17 can move back and forth between the shallow hole 151 and the deep hole 152. Furthermore, a positioning groove 222 is provided on the portion of the pipeline pulling rod 22 extending into the fixing seat 16. When the shallow hole 151 and the through hole 161 cooperate, that is, when the shallow hole 151 is located at the corresponding position of the through hole 161, the locking steel ball 17 extends out of the through hole 161 and is locked into the positioning groove 222, so that the pipeline pulling rod 22 is fixed in the fixing seat 16 in a locked state; on the other hand, before the host socket 1 and the pipeline plug socket 2 are connected, the shallow hole 151 is also located at the corresponding position of the through hole 161, that is, the locking steel ball 17 is always located between the shallow hole 151 and the through hole 161 when the host socket 1 and the pipeline plug socket 2 are not connected. When the deep hole 152 and the through hole 161 cooperate, the push plate 12 drives the release sleeve 15 to move, so that the deep hole 152 is located at the corresponding position of the through hole 161, and the movable range of the locking steel ball 17 becomes wider, and it can move between the deep hole 152 and the through hole 161. The locking steel ball 17 can be separated from the positioning groove 222, so that the pipeline traction rod 22 can be separated from the fixed seat 16.

[0029] The quick-release button 13 includes a push head 132, and part of the push head 132 extends out of one end of the host socket 1, so that the user can operate the push head 132. The limiting hole 131 is arranged on the part of the push head 132 that has not extended out. A long plate 133 is arranged on one side of the lower end of the push head 132, and the long plate 133 is arranged in a sliding groove 135 inside the host socket 1. The fixed seat 16 passes through the long plate 133 and the sliding groove 135 and is fixedly connected to the host socket 1. A short plate 134 is arranged on the other side of the lower end of the push head 132, and the short plate 134 is arranged corresponding to the position of the push plate 12. The lower end of the push head 132 is also provided with a rebound device connected to the socket, and the sliding groove 135 and the rebound device cooperate with each other so that the long plate 133 can slide up and down in the sliding groove 135. Specifically, the rebound device includes a first return spring 136 fixed on the lower end surface of the pressing head 132. The host socket 1 is provided with a fixing platform 137 corresponding to the position of the first return spring 136. The fixing platform 137 is provided with a limiting column 138 extending into the first return spring 136. In order to limit the position of the first return spring 136 and prevent the first return spring 136 from moving in other directions during operation and affecting the operation effect of the pressing head 132, one end of the first return spring 136 abuts against the fixing platform 137. Push blocks 122 are provided on both sides of the push plate 12. The number of the short plates 134 is consistent with the number of the push blocks 122, and each of the short plates 134 is provided above each of the push blocks 122. The fixing seat 16 is also provided with a second return spring 18. One end of the second return spring 18 is connected to the release sleeve 15 to realize the movement and return action of the push block 122.

[0030] Specifically, when connecting the host socket 1 and the pipeline plug socket 2, the connecting piece 21 is aligned with the limiting hole 131, and the pipeline pulling rod 22 is aligned with the connecting hole 111. When the connecting piece 21 enters the limiting hole 131, preferably, the surface of the limiting block 139 and the end face of the connecting piece 21 close to the limiting block 139 are both inclined surfaces gradually inclined outward from top to bottom. The inclined surface of the connecting piece 21 and the inclined surface of the limiting block 139 abut against each other, and under the continued forward movement of the connecting piece 21, the limiting block 139 is squeezed and moved downward, and then the pressing head 132 is synchronously moved downward under the drive of the limiting block 139. Under the cooperation of the fixing platform 137 and the limiting column 138, the first return spring 136 is compressed downward, so that the short plate 134 moves downward. During the downward movement, the short plate 134 gradually approaches the The push block 122 is pushed until it abuts against the push block 122. Preferably, one end surface of the push block 122 close to the short plate 134 and one end surface of the short plate 134 close to the push block 122 are both inclined surfaces that gradually tilt outward from top to bottom. That is, when the short plate 134 continues to move downward against the push block 122, under the action of the inclined surfaces of the short plate 134 and the push block 122, the push block 122 drives the shaft sleeve 121 to move forward, so that the release sleeve 15 moves forward following the movement of the push plate 12. At this time, the release sleeve 15 squeezes the second return spring 18 forward and makes the deep hole 152 gradually approach the through hole 161 until the deep hole 152 and the through hole 161 are located at the same corresponding position, unlocking the locking steel ball 17 so that the locking steel ball 17 can extend into the deep hole 152, so that the pipeline traction rod 22 can enter the fixed seat 16. When the connecting member 21 moves to the point where the limit block 139 enters the slot 211, the first return spring 136 rebounds rapidly, that is, the pressing head 132 moves upward rapidly, and drives the short plate 134 to move upward. At this time, the release sleeve 15 moves backward under the rebound action of the second return spring 18, and drives the push plate 12 to move backward, so that the shallow hole 151 moves rapidly toward the position of the through hole 161, and partially pushes the positioning steel ball 17 out of the through hole 161, and locks the positioning steel ball 17, limiting the movement of the positioning steel ball 17, so that part of the positioning steel ball 17 is embedded in the positioning groove 222 of the pipeline traction rod 22, thereby realizing the fixed connection between the entire host socket 1 and the pipeline plug socket 2, and then the host traction guide wire 14 and the pipeline guide wire 221 are linked to start operation.

[0031] Similarly, when it is necessary to separate the host socket 1 and the pipeline plug socket 2, the quick release button 13 is pressed, that is, the pressing head 132 is pressed. When the pressing head 132 moves downward, the long plate 133 and the short plate 134 move downward at the same time, so that the limit block 139 gradually moves away from the slot 211, until the limit block 139 and the connector 21 extend out of the slot 211, and the connector 21 can extend out of the limit hole 131. In this process, the short plate 134 moves downward and drives the push plate 12 to move forward through the push block 122, and the release sleeve 15 moves forward under the drive of the shaft sleeve 121. , so that the deep hole 152 gradually moves toward the through hole 161, until the deep hole 152 matches the position of the through hole 161, unlocking the positioning steel ball 17, at this time, the positioning steel ball 17 can move within the range between the deep hole 152 and the through hole 161, that is, the positioning steel ball 17 can be separated from the positioning groove 222, so that the pipeline traction rod 22 is smoothly separated from the fixing seat 16 and extends out of the connecting hole 111, realizing the separation of the entire host socket 1 and the pipeline plug seat 2, that is, the host traction guide wire 14 and the pipeline guide wire 221 are disconnected and stopped. The whole process is simple to operate, convenient and fast, and the user can independently complete the rapid installation and disassembly of the host socket 1 and the pipeline plug seat 2, and can select the appropriate pipeline plug seat 2 at any time according to different use environments, that is, one host socket 1 can cooperate with multiple pipeline plug seats 2, without the need for customers to purchase multiple endoscopes with only different pipelines but the same other ends, which fundamentally reduces the use cost.

[0032] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions or improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
