[0052] Anti-fooling structure 4 Specific embodiments

[0053] The following is a preferred embodiment, and the present utility model will be more clearly and completely described in conjunction with the accompanying drawings.

[0054] This embodiment provides a pump body clamping and releasing mechanism, and the specific structure is as Figure 1 , Figure 2 , Figure 3 and Figure 4 shown. The pump body clamping and releasing mechanism 100 is arranged on the pump main body (not shown in the figure). The pump main body also includes a human-machine interface (not shown in the figure). The pump main body is a rectangular structure and has a receiving groove on the end face for receiving the pump body clamping and releasing mechanism 100. The pump body clamping and releasing mechanism 100 is located in the receiving groove and is flush with the end face or is spaced from the end face and does not protrude from the end face. The human-machine interface is a touch screen structure in the prior art, so that the operator can operate each function of the pump main body on the human-machine interface, which will not be elaborated here. The human-machine interface is located on the end face and on the side of the receiving groove.

[0055] The pump body clamping and releasing mechanism 100 includes:

[0056] The first locking part 1, the first locking part 1 is arranged in the insertion direction of the pump body 10, and the first locking part 1 is used to lock the piston rod 20 of the pump body 10;

[0057] The second locking part 2, the second locking part 2 is arranged perpendicular to the insertion direction of the pump body 10, and the second locking part 2 is used to lock the pump body 10;

[0058] The pump body 10 is electrically connected to the human-machine interface. When the first locking part 1 and / or the second locking part 2 locks the pump body 10 and / or the piston rod 20, the pump body 10 is turned on through the human-machine interface.

[0059] Specifically, the pump body clamping and releasing mechanism 100 is of a rectangular structure, and the first locking portion 1 is arranged along the insertion direction of the pump body 10. There are two piston rods 20 arranged on the pump body 10. The first locking portion 1 arranged along the insertion direction of the pump body 10 is used to lock the two piston rods 20, so as to realize the locking of the pump body 10 when the pump body 10 is inserted into the pump body clamping and releasing mechanism 100. There is no need to set an inductor to identify whether the locking is in place. In addition, the pump body 10 is electrically connected to the human-machine interface, so that after the pump body 10 is inserted into the pump body clamping and releasing mechanism 100, the operator can turn on the pump body 10 through the human-machine interface without waiting, with a faster response and avoiding the situation that the pump body 10 may not be installed in place and cannot be recognized after installation. At the same time, it avoids the situation that the pump body 10 needs to wait to be turned on after being installed in place. The first locking portion 1 locks by mechanical locking, which can avoid being affected by the service life of the inductor. In addition, when the pump body 10 is turned on through the human-machine interface of the pump main unit, that is, the pump body 10 is integrated into the human-machine interface. Compared with the method of additionally setting an operating head or a screen for operation, its manufacturing cost is lower and the space occupied by the pump main unit is less.

[0060] Similarly, the second locking portion 2 is arranged along a direction perpendicular to the insertion direction of the pump body 10. The pump body 10 includes a rectangular housing, and two piston rods 20 extend from the housing. The second locking portion 2 arranged along a direction perpendicular to the insertion direction of the pump body 10 is used to lock the housing of the pump body 10. The first locking portion 1 and the second locking portion 2 cooperate to effectively lock the pump body 10 when it is inserted into the pump main unit by increasing the locking structure. Locking the pump body 10 from different directions can ensure that the pump body 10 is installed in place after insertion, improve the locking effect on the pump body 10, ensure that the pump body 10 is installed in place after being inserted into the pump main unit, and there is no need for an inductor to detect.

[0061] In this embodiment, the first locking portion 1 includes a driving motor 11 and a first locking member 12. The driving motor 11 is arranged on the bottom plate 101 of the pump body clamping and releasing mechanism 100. The output shaft 111 of the driving motor 11 makes a reciprocating motion along the insertion direction of the pump body 10. The first locking member 12 is arranged on the output shaft 111 and the first locking member 12 is used to insert into the piston rod 20 along the insertion direction of the pump body 10. A limiting portion 3 is arranged at the end of the piston rod 20 facing the first locking member 12.

[0062] Specifically, the drive motor 11 is a servo motor in the prior art. An output shaft 111 extends from the drive motor 11. The output shaft 111 is arranged along the insertion direction of the pump body 10 and can reciprocate along the insertion direction of the pump body 10. The first locking member 12 is arranged on the output shaft 111 to approach the end of the piston rod 20 when the output shaft 111 reciprocates and is inserted into the piston rod 20. A limiting portion 3 is arranged on the piston rod 20. The limiting portion 3 is sleeved on the piston rod 20 and abuts against the first locking member 12 to lock the piston rod 20. The limiting portion 3 can be a clamping structure arranged in the radial direction of the piston rod 20 in the prior art, which will not be elaborated here. The working principle of the first locking portion 1 is as follows. First, when the pump body 10 has not been inserted into the pump body detachment mechanism 100, the drive motor 11 keeps the output shaft 111 at a preset locking position. When the operator inserts the pump body 10, the piston rod 20 extends into the pump body detachment mechanism 100 and is inserted into the first locking member 12, and the locking is achieved through the limiting portion 3. It is locked immediately after insertion, and the operator can operate through the human-machine interface to connect the pump body 10 without waiting. When unlocking the piston rod 20, the drive motor 11 is operated and connected through the human-machine interface to drive the first locking member 12 on the output shaft 111 to move away from the piston rod 20, thereby unlocking the piston rod 20.

[0063] Further, the first locking portion 1 further includes a slider 13 and a slide rail 14. The slide rail 14 is arranged along the insertion direction of the pump body 10 and is located on the bottom plate 101. The slider 13 is slidably connected to the slide rail 14. The first locking member 12 is arranged on the slider 13 and is located on the surface of the slider 13 away from the slide rail 14.

[0064] Specifically, two slide rails 14 parallel to each other are arranged on the bottom plate 101. The slider 13 is located above the slide rails 14, and rollers are further arranged between the slider 13 and the slide rails 14. The rollers are in the prior art and will not be elaborated here. Some rollers are rotatably connected in the slide rails 14. The rollers are connected to the slider 13 through a rotating shaft. An installation hole is formed in the slider 13, and the output shaft 111 passes through the installation hole so that the slider 13 is driven by the output shaft 111 and moves along the slide rail 14. The first locking member 12 is arranged on the slider 13 and is arranged away from the slide rail 14, so that the slider 13 supports the first locking member 12, enabling the first locking member 12 to correspond to the piston rod 20. Compared with the coaxial arrangement of the first locking member 12 and the output shaft 111, it occupies less space in the pump main body. At the same time, it avoids the situation where the first locking member 12 may interfere with other structures in the pump body detachment mechanism 100 when arranged on other surfaces of the slider 13.

[0065] In this embodiment, a protrusion 131 is provided on the surface of the slider 13 facing the first locking member 12 , and a groove (not shown) is provided on the first locking member 12 corresponding to the protrusion 131 , and an anti-fouling structure 4 is provided on the protrusion 131 and the groove.

[0066] Specifically, the protrusion 131 is a cylindrical structure, and the groove has the same shape as the protrusion 131. In this embodiment, the anti-fool structure 4 is a cut edge set on the side of the protrusion 131, so that the protrusion 131 is an elliptical structure when viewed from a top view. Similarly, the groove is also an elliptical structure, so that when the first locking member 12 is connected to the slider 13 through the protrusion 131, it is ensured that the end face of the first locking member 12 always corresponds to the insertion direction of the pump body 10, preventing the end face of the first locking member 12 from being skewed when it is installed, making it easy for the operator to install the first locking member 12 and ensuring that the end face will not be skewed and unable to lock the piston rod 20.

[0067] In other embodiments, the anti-mistake structure 4 can also be a "T"-shaped structure when the protrusion 131 is viewed from a top view, and the groove has the same shape as the protrusion 131, so as to ensure the end face position when the first locking member 12 is installed on the slider 13, prevent the first locking member 12 from being misaligned with the piston rod 20, and ensure the reliability of installing the first locking member 12 and locking the piston rod 20.

[0068] In this embodiment, a locking hole (not shown in the figure) is provided at the end of the first locking member 12 corresponding to the piston rod 20 , and the limiting portion 3 is a conical structure and is arranged toward the locking hole.

[0069] Specifically, the conical structure is sleeved on the piston rod 20, and the end with a smaller size along the length direction of the piston rod 20 is arranged toward the locking hole, and the diameter of the larger end is larger than the diameter of the piston rod 20, so as to achieve an interference fit when the piston rod 20 is inserted into the locking hole of the first locking member 12, thereby effectively locking the piston rod 20.

[0070] In this embodiment, the first locking portion 1 further includes a first support member 15 , which is disposed on the bottom plate 101 and located at both ends of the slider 13 . The first support member 15 is provided with a hole, and the output shaft 111 extends into the hole.

[0071] Specifically, the first support member 15 is a "T"-shaped structure, and two first support members 15 are provided. One first support member 15 is arranged close to the drive motor 11, and the other first support member 15 is connected to the end of the output shaft 111 away from the drive motor 11. It can be understood that the slider 13 moves between the two first support members 15. The first support member 15 is arranged to support and guide the cantilevered output shaft 111 to prevent the output shaft 111 from deviating from the insertion direction of the pump body 10 when it reciprocates.

[0072] In this embodiment, the second locking portion 2 includes a driving unit 21 and a clamping unit 22. The driving unit 21 is used to drive the clamping unit 22 to approach or move away from the pump body 10 along a direction perpendicular to the insertion direction of the pump body 10.

[0073] Specifically, the second locking portion 2 is disposed at an end close to the receiving groove. The driving unit 21 is disposed perpendicular to the output shaft 111. The clamping unit 22 is driven by the driving unit 21 to approach or move away from the pump body 10. When the first locking portion 1 locks the piston rod 20, the driving unit 21 drives the clamping unit 22 to clamp the housing of the pump body 10, so as to lock the pump body 10 from different directions and improve the locking effect.

[0074] In this embodiment, the driving unit 21 is a screw. A positive thread (not shown in the figure) is provided at the first end of the screw, and a reverse thread (not shown in the figure) is provided at the second end of the screw. The clamping unit 22 is a nut screwed to both ends of the screw.

[0075] Specifically, the screw is disposed along a direction perpendicular to the output shaft 111 and close to the end face of the receiving groove. A positive thread is provided in the screw from the first end to the middle region of the screw. The positive thread is a thread provided in the prior art in the clockwise direction, while the reverse thread is a thread provided in the prior art in the counterclockwise direction. The screw can rotate to make the nuts at both ends of the screw approach or move away from the middle region of the screw, so as to clamp the housing of the pump body 10. It can be understood that the rotation of the screw can be realized by an operator screwing it, or by driving the screw to rotate by a motor. This is the prior art and will not be elaborated here.

[0076] In this embodiment, the second locking portion 2 further includes a second support member 23. The second support member 23 is disposed at both ends of the screw, and through holes are provided in the second support member 23. The screw passes through the through holes.

[0077] Specifically,

[0078] The second support member 23 has a "T" - shaped structure. There are two second support members 23. One second support member 23 is located above the output shaft 111, and the other second support member 23 is located below the output shaft 111. It can be understood that the screw passes through the through holes and can rotate, so as to facilitate the screw to rotate by itself and drive the nut to move. By providing the second support member 23, the rotating screw is supported and guided to prevent the screw from deviating from the direction perpendicular to the insertion direction of the pump body 10 during rotation.

[0079] This embodiment also provides a water - jet medical pump main machine system. The water - jet medical pump main machine system includes the above - mentioned pump body clamping and releasing mechanism 100. Compared with setting an inductor for induction and connecting the pump body 10, there is no need to wait, the response is faster, and the locking of the pump body 10 is more reliable. The operator can connect the pump body 10 on the human - machine interaction interface, and the integration degree is higher.
