A first channel is provided in the first base 310. The first channel may include a first pipe 411, which extends in the front-rear direction. The first end of the first pipe 411 extends in the rear direction and connects to the medium input end 450, which may be located on the rear end face of the first base 310. The second end of the first pipe 411 extends in the forward direction and connects to the second pipe 412.

The first end of the second pipe 412 extends downward and connects to the first pipe 411, while the second end extends upward until it reaches the base protrusion 350. The connecting shaft 380 extends in the left-right direction and is fixedly connected to the adapter block 360. In some cases, the connecting shaft 380 and the adapter block 360 are integrated. A first rotating hole and a second rotating hole are provided in opposite directions in the base protrusion 350. One end of the connecting shaft 380 is located in the first rotating hole, and the other end is located in the second rotating hole, allowing the connecting shaft to rotate relative to the base protrusion 350. A second channel can be provided in the adapter block 360. The second channel may include a third conduit 423.

The second end of the aforementioned second conduit 412 extends to the third conduit 423. The channel may also include a fourth conduit 421. For example, a fourth conduit 421 extending left and right is provided in the connecting shaft 380. The connecting shaft 380 is provided with at least one first connecting hole 441 at a position corresponding to the third conduit 423. Since the third conduit 423 is formed by an annular groove structure, when the connecting shaft 380 rotates relative to the base protrusion 350, the fourth conduit 421 is continuously connected to the third conduit 423 through the first connecting hole 441. A fifth conduit 422 is provided in the adapter block 360. The fifth conduit 422 extends in the front-back direction, and the first end of the fifth conduit 422 extends in the forward direction.

The instrument interface 210 is connected with the measurement end of the pressure instrument, so that the pressure instrument can measure the medium pressure of the pressure transmission medium. In another example of the present application, if the instrument joint 200 is directly connected with the first base 310 in a rotating manner, the aforementioned connection shaft 380 can be arranged on the instrument joint 200, and the instrument joint 200 is connected with the base block 350 in a rotating manner through the connection shaft 380. It can be understood that the first channel can have other forms, and the rotating connection structure between the instrument joint 200 and the first base 310 can have other forms. According to the rotating connection structure between the instrument joint 200 and the first base 310, the channel for transmitting the pressure transmission medium between the first channel and the instrument interface can also have other forms.

[0050] The instrument joint 200 is drivingly connected with the second base 320 through a transmission structure. In some examples of the present application, the instrument joint 200 is drivingly connected with the connection shaft 380, and the instrument joint 200 can be fixed with the connection shaft 380 through the adapter block 360, or the instrument joint 200 can be directly fixed with the connection shaft 380. A gear can be arranged in the second base 320, the connection shaft 380 can be drivingly connected with the central shaft of the gear through a transmission belt, a toothed chain guide rail is arranged in the connection base 330, the gear is engaged with the toothed chain guide rail, and when the instrument joint 200 rotates relative to the first base 310, the connection shaft 380 rotates relative to the first base 310. The connection shaft 380 drives the gear to rotate through the transmission belt, and the gear moves along the gear guide rail, so as to convert the rotational torque into a linear torque. Further, when the instrument joint 200 rotates from the interface upward to the interface forward, the connection shaft 380 rotates clockwise, the connection shaft 380 drives the gear to rotate clockwise, the gear moves in the forward direction along the toothed chain guide rail, and the gear drives the second base 320 to move forward, so as to drive the image acquisition module 100 to move forward. In another example of the present application, at least part of the transmission structure in the foregoing example can be changed into a connecting rod structure. The connection structure can be a combination of a single connecting rod and a gear or other transmission structure, or can be a combination of at least two connecting rods, so as to convert the rotational torque output by the connection shaft 380 into a linear torque. The specific structure form for realizing the transmission structure can also have many forms.

[0051] In some examples of the present application, if the pressure instrument is a radial pressure gauge, such asFigure 5 As shown, Figure 5 This is a left view of the pressure detection device's instrument connector 200 when it is at the first angle. The instrument connector 200 is located at the first angle, the interface direction of the instrument interface 210 is upward, and the image acquisition direction of the image acquisition module 100 is backward. The interface direction and the image acquisition direction are perpendicular to each other. The distance between the first base 310 and the second base 320 is the first base distance, which can be zero or a very small gap. If the pressure gauge is an axial pressure gauge, such as... Figure 6 As shown, Figure 6 This is a left view of the pressure detection device when the instrument connector 200 is in the second angle. The instrument connector 200 is located in the second angle, the interface direction of the instrument connector 210 is forward, the image acquisition direction of the image acquisition module 100 is backward, the interface direction is opposite to the image acquisition direction, and the distance between the first base 310 and the second base 320 is the second base distance, which is greater than the first base distance.

[0052] One advantage of this application embodiment is improved operational efficiency. Specifically, in related technologies, the instrument connector and the image acquisition module are driven independently. The preparation stage includes two steps. In the first step, the pressure gauge is installed on the instrument connector and the instrument connector is rotated to the corresponding angle. Based on the first step, the second step is performed, adjusting the position of the image acquisition module according to the instrument imaging in the image acquisition module. The difference between this application embodiment and related technologies is that the torque of rotating the instrument connector 200 drives the second base 320 to move through the transmission structure. When the instrument connector 200 rotates from the first angle to the second angle, the second base 320 also reaches the corresponding position, reducing the number of operation steps and improving operational efficiency.

[0053] The second advantage of this application embodiment is that it reduces the driving requirements. Specifically, in related technologies, driving the instrument connector to rotate requires one driving source, and driving the image acquisition module to move requires another driving source. If the driving source is manual, as one of the aforementioned advantages states, the operating efficiency of related technologies is significantly lower than that of this application embodiment. If the driving source is automatic, related technologies require two driving sources, such as two motors. In contrast, this application embodiment only requires one driving source, which can reduce equipment costs and reduce equipment size.

[0054] In some examples of the embodiments of the present application, the first base 310 movably covers the second base 320, the length of the first base 310 in the image acquisition direction is less than or equal to 45 cm, and when the instrument joint 200 is at the second angle, the second base 320 extends from the first base 310; or, the second base 320 movably covers the first base 310, the length of the second base 320 in the image acquisition direction is less than or equal to 45 cm, and when the instrument joint 200 is at the second angle, the first base 310 extends from the second base 320.

[0055] For example, the first base 310 is integrated with the connecting base 330, the connecting base 330 is equivalent to a part of the first base 310, the first base 310 has a first length L1 in the front-rear direction, and the second base 320 has a second length L2 in the front-rear direction, as shown in Figure 5 When the instrument joint 200 is at the first angle, the first base 310 and the second base 320 have a first base distance therebetween, and correspondingly, the length of the pressure detection device in the front-rear direction is equal to or slightly greater than the length of the first base 310, that is, equal to or slightly greater than L1, as shown in Figure 6 When the instrument joint 200 is at the second angle, the first base 310 and the second base 320 have a second base distance therebetween, and the second base 320 extends from the connecting base 330, at this time, the length of the pressure detection device in the front-rear direction is equal to or slightly less than the sum of the lengths of the first base 310 and the second base 320, that is, close to the sum of L1 and L2, and obviously, Figure 6 The length of the pressure detection device in the case shown in Figure 5 is obviously greater than the length of the pressure detection device in the case shown in For example, the second base 320 is integrated with the connecting base 330, the connecting base 330 is equivalent to a part of the second base 320, and similar to the previous example, when the instrument joint 200 is at the first angle, the length of the pressure detection device in the front-rear direction is equal to or slightly greater than the length of the second base 320, and when the instrument joint 200 is at the second angle, the length of the pressure detection device in the front-rear direction is equal to or slightly less than the sum of the lengths of the first base 310 and the second base 320, and obviously greater than the length of the second base 320.

[0056] The third advantage of the embodiment of the present application is that the pressure instrument, in particular the axial pressure gauge, is convenient to install. Specifically, in the related art, for example, in the pressure detection bench, the length of the bench body is generally more than 80 cm, the first base and the second base are located on the bench body, in order to ensure that the first base and the second base have sufficient movement space, the bench body needs to be long enough, which will affect the detection personnel installing the pressure instrument. Unlike the prior art, in the embodiment of the present application, before installing the axial pressure gauge, the instrument joint can be rotated to the first angle. At this time, the pressure detection device has a relatively short length in the front-rear direction, and the detection personnel can be located in front of the pressure detection device. The detection personnel can observe the installation situation while installing the pressure instrument. After installation is completed, the instrument joint is rotated to the second angle. At this time, the pressure detection device can have a relatively long length in the front-rear direction, so as to form sufficient image acquisition space between the image acquisition module and the pressure instrument. Similarly to the foregoing advantage, when carrying the pressure detection device, the instrument joint can be rotated to the first angle to reduce the length of the pressure detection device, improve the convenience of carrying, and also reduce the risk of disengagement between the two bases connected in motion during carrying.

[0057] In some examples of the embodiment of the present application, the first base 310 is provided with a first guide structure, and the second base 320 is provided with a second guide structure. The first guide structure and the second guide structure are connected in sliding along the image acquisition direction.

[0058] For example, the guide structure can include a sliding rail and a sliding block. The sliding rail extends in the front-rear direction, and the sliding block can move along the sliding rail. In some cases, the sliding rail can be provided on the first base, the first base and the connecting base are integrated, and the second base is connected in sliding with the connecting base. The sliding block can be provided on the second base. In some other cases, the sliding block can be provided on the first base, the first base and the connecting base are integrated, and the second base is connected in sliding with the connecting base. The sliding block can be provided on the second base. In some other cases, the sliding rail can be provided on the second base, the second base and the connecting base are integrated, and the first base is connected in sliding with the connecting base. The sliding block can be provided on the first base. In some other cases, the sliding block can be provided on the second base, the second base and the connecting base are integrated, and the first base is connected in sliding with the connecting base. The sliding rail can be provided on the first base. For another example, the guide structure can also include a gear and a rack. The rack extends in the front-rear direction. For another example, the guide structure can also have other structural forms.

[0059] For example, the first base 310 is integrated with the connecting base 330, a guide cavity can be arranged in the connecting base 330, the guide cavity extends in the front-rear direction, the second base 320 is movably connected with the connecting base 330, the second base 320 includes a guide extension 321 extending in the front-rear direction, the inner periphery contour of the guide cavity is matched with the outer periphery contour of the guide extension 321, the guide cavity can be sleeved on the guide extension 321, as shown in Figure 5 , when the instrument joint 200 is at the first angle, the guide extension 321 is retracted in the guide cavity, so that the pressure detection device has a smaller length in the front-rear direction, when the instrument joint 200 rotates from the first angle to the second angle, the rotation torque of the instrument joint 200 is transmitted to the second base 320 through the transmission structure, the guide extension 321 moves along the guide cavity, the guide cavity guides the guide extension 321, so that the guide extension 321 extends in the front direction until, as shown in Figure 6 , when the instrument joint 200 is at the second angle, the guide extension 321 extends out of the guide cavity, so that the pressure detection device has a larger length in the front-rear direction. For another example, the second base can be sleeved on the connecting base, correspondingly, the guide cavity can be arranged in the second base, and the guide extension can be arranged in the connecting base.

[0060] In some examples of the embodiment of the present application, the transmission structure includes: a rack 312, the rack 312 is drivingly connected with the second base 320; a gear 311, the gear 311 is engaged with the rack 312, the instrument joint 200 is drivingly connected with the gear 311, wherein, when the instrument joint 200 rotates from the first angle to the second angle, the rotation torque of the instrument joint 200 drives the gear 311 to rotate, and the gear 311 drives the rack 312 to move away from the image capturing direction.

[0061] For example, as shown in Figure 7 , the sectional view of the pressure detection device is shown in Figure 7 , and the sectional position is shown in Figure 7 , and the sectional position is shown in Figure 4The cross-sectional positions of the first base 310 and the second base 320 can be the same or different. The aforementioned transmission structure can include a gear 311 and a rack 312. The first base 310 is integrated with the connecting base 330. The first base 310 has a transmission accommodating cavity for accommodating the transmission structure. The transmission accommodating cavity has a gear support structure. The gear 311 is arranged in the transmission accommodating cavity. The central axis of the gear 311 is rotationally connected with the gear support structure. The rack 312 is movably arranged in the transmission accommodating cavity. The rack 312 is clamped between the gear 311 and the inner wall of the transmission accommodating cavity. When the gear 311 rotates relative to the gear support structure, the relative position between the gear 311 and the inner wall of the transmission accommodating cavity remains unchanged, so that the gear 311 and the rack 312 are engaged. The instrument connector 200 is drivingly connected with the gear 311. Specifically, the instrument connector 200 can be drivingly connected with the gear 311 through a first transmission part. The first transmission part can be a belt, a gear, a swing rod or other transmission structure. When the instrument connector 200 rotates relative to the first base 310, the instrument connector 200 outputs a rotation torque. The rotation torque can be transmitted to the gear 311 through the first transmission part, so as to drive the gear 311 to rotate. Further, when the instrument connector 200 rotates from the first angle to the second angle, the rotation torque can drive the gear 311 to rotate in the counterclockwise direction in the figure. The gear 311 continuously engages with the rack 312, so as to drive the rack 312 to move in the forward direction. The rack 312 is drivingly connected with the second base 320. For example, the rack 312 is fixedly connected with the second base 320. For another example, the rack 312 can be drivingly connected with the second base 320 through other transmission structure. The rack 312 drives the second base 320 to move in the forward direction, i.e. drives the second base 320 and the image acquisition module 100 located above the second base 320 to move away from the image acquisition direction. When the instrument connector 200 rotates from the second angle to the first angle, the rotation torque can drive the gear 311 to rotate in the clockwise direction in the figure, so as to drive the rack 312 to move in the backward direction. Further, the backward movement of the rack 312 can drive the second base 320 to move in the backward direction.

[0062] In some examples of the embodiments of the present application, the pressure detection device can further comprise the following structure: the instrument joint 200 and the gear 311 are drivingly connected in a decoupling manner; or, the rack 312 and the second base 320 are drivingly connected in a decoupling manner; or, the gear 311 and the rack 312 are meshed in a decoupling manner, wherein the first base 310 comprises: a first housing 313, the first housing 313 is rotationally connected with the central shaft of the gear 311; a second housing 314, the second housing 314 is detachably fixed to the first housing 313, when the first housing 313 and the second housing 314 are closed, the second housing 314 and the gear 311 form a space suitable for the rack 312, the second housing 314 and the gear 311 sandwich the rack 312, when the first housing 313 and the second housing 314 are separated, the gear 311 and the rack 312 are decoupled.

[0063] For example, the instrument joint 200 and the second base 320 are drivingly connected in a decoupling manner, when the instrument joint 200 and the second base 320 are coupled, the instrument joint 200 and the second base 320 follow the movement, when the instrument joint 200 and the second base 320 are decoupled, the instrument joint 200 can move independently relative to the second base 320, if the second base 320 is pulled away from the image acquisition direction, the instrument joint 200 can remain stationary relative to the first base 310, if the instrument joint 200 rotates from the first angle to the second angle, the second base 320 can remain stationary relative to the first base 310. The instrument joint 200 and the second base 320 are drivingly connected in a decoupling manner through the transmission structure, accordingly, when the instrument joint 200 and the transmission structure are decoupled, the instrument joint 200 and the second base 320 can move independently relative to each other, when the transmission structure is decoupled internally, the instrument joint 200 and the second base 320 can move independently relative to each other, when the second base 320 and the transmission structure are decoupled, the instrument joint 200 and the second base 320 can move independently relative to each other.

[0064] For example, to realize the decoupling inside the transmission structure, the gear 311 and the rack 312 are drivingly connected in a decoupling manner, specifically, as shown in Figure 7As shown, the first base 310 is integrated with the connecting base 330, which can be regarded as a part of the first base 310. The first base 310 includes a first housing 313 and a second housing 314, and a transmission accommodating cavity 315 is formed between the first housing 313 and the second housing 314. A gear support structure 316 is fixed in the transmission accommodating cavity 315. The central axis of the gear 311 is rotationally connected with the gear support structure 316. The gear 311 can rotate about the central axis relative to the first base 310. When the first housing 313 and the second housing 314 are in the closed state, the distance between the gear 311 and the second housing 314 is equal to the height of the rack 312. The rack 312 is just clamped by the gear 311 and the second housing 314. The gear 311 and the rack 312 are engaged. When the gear 311 rotates, it can drive the rack 312 to move in the front-rear direction. The first housing 313 and the second housing 314 have separable connecting structures, such as buckle structures, which can separate the first housing 313 and the second housing 314. When the first housing 313 and the second housing 314 are in the fully separated state or the partially separated state, the distance between the gear 311 and the second housing 314 is greater than the height of the rack 312. Under the influence of gravity or the driving force of the gear 311, the gear 311 and the rack 312 are separated, and the gear 311 and the rack 312 are decoupled. At this time, if the instrument connector 200 rotates, the gear 311 rotates with the instrument connector 200. Since the gear 311 and the rack 312 are decoupled, the torque will not be transmitted to the second base 320, and the relative position of the second base 320 and the first base 310 remains unchanged. If the relative position between the first base 310 and the second base 320 is adjusted, the rack 312 moves linearly with the linear motion of the second base 320. Since the gear 311 and the rack 312 are decoupled, the rotational torque will not be transmitted to the gear 311, and the gear 311 will not rotate. Correspondingly, the instrument connector 200 will not rotate.

[0065] For example, the instrument joint 200 and the gear 311 are drivingly connected in a decoupled manner, and when the instrument joint 200 and the gear 311 are drivingly connected, the instrument joint 200 and the gear 311 are in follow-up movement, the instrument joint 200 and the second base 320 are in follow-up movement, and when the instrument joint 200 and the gear 311 are decoupled, the instrument joint 200 and the gear 311 can move relatively independently, and the instrument joint 200 and the second base 320 can move relatively independently; for another example, the second base 320 and the gear rack 312 are drivingly connected in a decoupled manner, and when the gear rack 312 and the second base 320 are drivingly connected, the gear rack 312 and the second base 320 are in follow-up movement, the instrument joint 200 and the second base 320 are in follow-up movement, and when the gear rack 312 and the second base 320 are decoupled, the gear rack 312 and the second base 320 can move relatively independently, and the instrument joint 200 and the second base 320 can move relatively independently.

[0066] The fourth advantage of the embodiment of the present application is that, on the one hand, when the instrument joint 200 and the second base 320 are drivingly connected, the relative position between the first base 310 and the second base 320 can be adjusted according to the rotational movement of the instrument joint 200, and on the other hand, the relative position between the first base 310 and the second base 320 can be adjusted independently.

[0067] In some examples of the embodiment of the present application, the transmission structure further comprises: a first eccentric shaft, the instrument joint 200 and a first shaft rod 511 of the first eccentric shaft are drivingly connected, a housing of the first base 310 comprises opposite first and second housing positions 531 and 532, when the instrument joint 200 rotates from a first angle to a second angle, a first eccentric part 512 of the first eccentric shaft moves between the first housing position 531 and the first shaft rod 511, and a distance between the second housing position 532 and the first shaft rod 511 is greater than a distance between the first housing position 531 and the first shaft rod 511; a second eccentric shaft, a second shaft rod 521 of the second eccentric shaft is drivingly connected with a central shaft of the gear 311; a driving rod 540, a first end of the driving rod 540 is in force connection with the first eccentric part 512 of the first eccentric shaft, and a second end of the driving rod 540 is drivingly connected with a second eccentric part 522 of the second eccentric shaft; a motor, an output shaft of the motor is drivingly connected with the central shaft of the gear 311, and a circumferential contour of the motor is less than or equal to a circumferential contour of the gear 311.

[0068] In some cases, the instrument connector 200 can be driven to connect with the gear 311 through a symmetrical transmission structure, such as a gear and rack structure or a belt structure. For such a symmetrical transmission structure, sufficient structural space needs to be distributed around the rotational connection position of the instrument connector 200, such as around the connecting shaft 380. Consequently, the volume of the first base 310 will increase, for example, the volume of the base protrusion 350 will increase. The increased volume of the base protrusion 360 will affect the rotational operating space of the instrument connector 200. In order to solve the aforementioned technical problems, this application provides an asymmetrical transmission structure.

[0069] For example, such as Figure 7 As shown, the first eccentric shaft includes a first shaft 511 and a first eccentric part 512. The connecting shaft 380 is fixedly connected to or integrally formed with the first shaft 511. When the instrument connector 200 rotates, the instrument connector 200 drives the adapter block 360 to rotate relative to the first base 310. The connecting shaft 380 rotates along its central axis. Correspondingly, the first eccentric part 512 rotates eccentrically around the first shaft 511. The first eccentric part 512 is rotatably connected to the first end of the drive rod 540. The eccentric rotation of the first eccentric part 512 drives the drive rod 540. When the rod 540 moves, the second eccentric shaft includes a second shaft 521 and a second eccentric part 522. The second shaft 521 is fixedly connected to or integral with the central shaft of the gear 311. When the drive rod 540 moves with the first eccentric part 512, the drive rod 540 drives the second eccentric part 522 to move. The second eccentric part 522 moves eccentrically around the second shaft 521. Correspondingly, the eccentric movement of the second eccentric part 522 drives the gear 311 to rotate around its central shaft. The gear 311 meshes with the rack 312, thereby driving the second base 320 to move linearly.

[0070] The fourth advantage of this application embodiment is that it provides a torque transmission method different from the prior art. Since the instrument connector 200 rotates between the first angle and the second angle, the torque is transmitted through the first eccentric shaft, and the first eccentric part 512 moves between the first housing position 531 and the first shaft 511. Correspondingly, a smaller space can be set between the second housing position 532 and the first shaft 511, which can reduce the volume of the first base 310. For example, the volume of the base protrusion 350 can be reduced, improving the rotation operation space of the instrument connector 200 and improving the user experience.

[0071] In some examples of the embodiments of the present application, the transmission structure comprises: a traction part, the traction part is drivingly connected with the second base 320, the instrument joint 200 is drivingly connected with the traction part, when the instrument joint 200 rotates from the first angle to the second angle, the traction part drives the second base 320 to move in a direction opposite to the image acquisition direction; an elastic part, a first end of the elastic part is stress-connected with the traction part, when the instrument joint 200 is located at the first angle, the elastic part has a first elastic potential energy, the first elastic potential energy is used to provide a pre-tightening force to the traction part, the pre-tightening force is in the same direction as the image acquisition direction, when the instrument joint 200 rotates from the first angle to the second angle, the elastic potential energy of the elastic part increases; a first locking part, when the instrument joint 200 is located at the second angle, the traction part is lockingly connected with the first base through the first locking part; or a second locking part, when the instrument joint 200 is located at the second angle, the second base 320 is lockingly connected with the first base through the second locking part.

[0072] For example, the traction part can be the rack 312 as described above, or can be a belt, a traction rope or other transmission structures, the instrument joint 200 is drivingly connected with the second base 320 through the traction part, when the instrument joint 200 rotates from the first angle to the second angle, the traction part converts the rotating torque output by the instrument joint 200 into a linear torque, and then drives the second base 320 to move in the forward direction, that is, in a direction opposite to the image acquisition direction. In the embodiments of the present application, the first base 310 is fixedly connected with or integrated with the connecting base 330, accordingly, the first base 310 and the connecting base 330 as described above can also be fixedly connected or integrated, and the connecting base 330 can be equivalent to a part of the first base 310, and the traction part can be wholly or partially arranged in a cavity inside the first base 310.

[0073] The transmission structure further comprises an elastic part, a first end of the elastic part is in force connection with the traction part, and a second end of the elastic part is in force connection with the first base 310; in some cases, the elastic part is compressibly arranged between the first base 310 and the traction part, when the instrument joint 200 is located at the first angle, the elastic part is in a compressed state and has a first elastic potential energy, a compression movement direction of the elastic part is opposite to the image acquisition direction, when the instrument joint 200 moves from the first angle to the second angle, the traction part moves away from the image acquisition direction, the traction part compresses the elastic part, the elastic potential energy of the elastic part increases, when the instrument joint 200 is located at the second angle, the elastic part is in a compressed state and has a second elastic potential energy, the second elastic potential energy is greater than the first elastic potential energy; in other cases, the elastic part is tensibly arranged between the first base 310 and the traction part, when the instrument joint 200 is located at the first angle, the elastic part is in a tensed state and has a first elastic potential energy, a tensing movement direction of the elastic part is opposite to the image acquisition direction, when the instrument joint 200 moves from the first angle to the second angle, the traction part moves away from the image acquisition direction, the traction part stretches the elastic part, the elastic potential energy of the elastic part increases, when the instrument joint 200 is located at the second angle, the elastic part is in a tensed state and has a second elastic potential energy, the second elastic potential energy is greater than the first elastic potential energy.

[0074] The transmission structure further comprises an elastic locking part, the elastic locking part can comprise a first locking part, wherein, when the instrument joint 200 is located at the second angle, the first locking part is located between the traction part and the first base, for example, the first locking part is located between the traction part and the first base 310, and for another example, the first locking part is located between the traction part and the connecting base 330, the first locking part is in locking connection with the traction part and the first base, the first base provides a traction force to the traction part, the traction force has the same size and opposite direction as the elastic force provided by the elastic part, the relative position between the traction part and the first base remains unchanged, so that the relative position between the second base 320 and the first base remains unchanged; the elastic locking part can also comprise a second locking part, wherein, when the instrument joint 200 is located at the second angle, the second locking part is located between the second base 320 and the first base, for example, the second locking part is located between the second base 320 and the connecting base 330, and for another example, the second locking part is located between the second base 320 and the first base 310, the second locking part is in locking connection with the second base 320 and the first base, the second base 320 provides a support force to the first base, the support force has the same size and opposite direction as the elastic force provided by the elastic part, the relative position between the second base 320 and the first base remains unchanged.

[0075] The fifth advantage of the embodiment of the present application is that when the instrument joint 200 is at the first angle, the elastic part can provide a pre-tightening force, which reduces the risk of shaking of the instrument joint 200 when the pressure detection device is moved. When the instrument joint 200 is at the second angle, the first locking part or the second locking part can keep the instrument joint 200 stable with the second base 320. Further, after the detection of the previous axial pressure gauge is completed, the elastic part can drive the second base 320 and the instrument joint 200 to automatically reset by unlocking the first locking part or the second locking part, thereby facilitating the installation of the next pressure gauge.

[0076] In some examples of the embodiment of the present application, the pressure detection device further comprises an adapter block 360. The adapter block 360 is provided with a mounting hole 361 at a first adapter position. The instrument joint 200 is detachably fixed to the mounting hole 361. The adapter block 360 is rotationally connected to the second base 320 at a second adapter position 362. When the instrument joint 200 is at the first angle, the second adapter position 362 is located between the first adapter position 361 and the image acquisition module 100.

[0077] For example, as shown in Figure 4 With Figure 5 As shown, the pressure detection device further comprises an adapter block 360. When the instrument joint 200 is at the first angle, the adapter block 360 extends along the front-back direction. The front part of the adapter block 360 is provided with a second adapter position 362. The adapter block 360 is rotationally connected to the first base 310 at the second adapter position 362. In some examples, the pressure detection device further comprises a connecting shaft 380. The connecting shaft 380 is arranged at the second adapter position 362. The adapter block 360 is rotationally connected to the first base 310 through the connecting shaft 380. The sixth advantage of the embodiment of the present application is that, on the one hand, when the instrument joint 200 rotates from the first angle to the second angle, the instrument interface 210 moves in the forward direction, that is, moves away from the image acquisition direction. In the present application, when the instrument joint 200 is at the first angle, the second adapter position 362 is located between the instrument joint 200 and the image acquisition module 100. Compared with the direct rotational connection of the instrument joint 200 with the first base 310, the adapter block can be arranged at a more rear position, thereby reducing the length of the pressure detection device in the front-back direction. On the other hand, the adapter block 360 is rotationally connected to the first base 310. The adapter block 360 is drivenly connected between the connecting shaft 380 and the gear 311, which can more conveniently replace the instrument joint 200 without the need to adjust the transmission structure.

[0078] In some examples of the embodiments of the present application, the first base 310 includes a first end surface 317, when the instrument joint is at the second angle, the adapter block 360 passes through the plane where the first end surface 317 is located, the adapter block 360 includes a second end surface 363, when the instrument joint 200 is at the first angle, the first end surface 317 and the second end surface 363 face the same direction, and the distance between the first end surface 317 and the second end surface 363 is less than or equal to 1 cm.

[0079] For example, as shown in FIG. 6, when the instrument joint 200 is at the first angle, the adapter block 360 includes the upward-facing second end surface 363, and the base protrusion 350 includes the first end surface 317 facing upward, at this time, the distance between the first end surface 317 and the second end surface 363 is less than or equal to 1 cm, so that when the adapter block 360 is held and rotated, the movement of the adapter block 360 can be reduced by the base protrusion 350, thereby improving the operation convenience. Figure 5

[0080] In some examples of the embodiments of the present application, when the instrument joint 200 is at the first angle, the instrument interface 210 and the first base 310 have a first vertical distance, when the instrument joint 200 is at the second angle, the instrument interface 210 and the first base 310 have a second vertical distance, and the first vertical distance is the same as the second vertical distance.

[0081] For example, as shown in FIG. 6, when the instrument joint 200 is at the first angle, the adapter block 360 includes the upward-facing second end surface 363, and the base protrusion 350 includes the first end surface 317 facing upward, at this time, the distance between the first end surface 317 and the second end surface 363 is less than or equal to 1 cm, so that when the adapter block 360 is held and rotated, the movement of the adapter block 360 can be reduced by the base protrusion 350, thereby improving the operation convenience. Figure 5 Figure 6 ​​As shown, when the instrument adapter 200 is at the first angle, the instrument interface 210 has a first vertical distance H1 from the plane on which the first end surface 317 is located, the plane on which the first end surface 317 is located has a third vertical distance H3 from the medium input end 450, and the height difference between the instrument interface 210 and the medium input end 450 is the sum of the first vertical distance H1 and the third vertical distance H3. When the instrument adapter 200 is at the second angle, the instrument interface 210 has a second vertical distance H2 from the plane on which the first end surface 317 is located. At this time, the height difference between the instrument interface 210 and the medium input end 450 is the sum of the second vertical distance H2 and the third vertical distance H3. In some cases, a pipeline connection is established between the medium input end 450 and the output end of the pressure controller, and the pressure controller can be replaced by other pressure generating devices or pressure control devices. At this time, the height difference between the output end of the pressure controller and the medium input end 450 is a fourth vertical distance H4. When the instrument adapter 200 is at the first angle, the height difference between the instrument interface 210 and the output end of the pressure controller is H1+H3+H4. At this time, the medium pressure difference caused by the height difference can be compensated for in any manner known in the art. When the instrument adapter 200 is rotated to the second angle after the pressure instrument is replaced, the height difference between the instrument interface 210 and the output end of the pressure controller is H2+H3+H4. Since the first vertical distance H1 and the second vertical distance H2 are the same, the height difference between the instrument interface 210 and the output end of the pressure controller does not change due to the rotation of the instrument adapter 200, and there is no need to recompensate. Compared with the need to recompensate every time, the pressure detection efficiency can be improved.

[0082] In some examples of the embodiments of the present application, a second channel is arranged in the adapter block 360, a first end of the second channel extends to the mounting hole 361, and forms a channel sealed from the outside between the instrument interface 210. A second end of the second channel forms a channel sealed from the outside between the first channel.

[0083] In some examples of the embodiments of the present application, the instrument adapter 200 includes a connecting rod 220 and a third locking portion. A third channel 430 is arranged in the connecting rod 220, a first end of the third channel 430 extends to the instrument interface 210, when the connecting rod 220 is inserted into the first position of the mounting hole 361, the connecting rod 220 is in sliding connection with the mounting hole 361, when the connecting rod 220 is inserted into the second position of the mounting hole 361 from the first position, the third locking portion is switched from the unlocked state to the locked state, the connecting rod 220 is in unlockable position connection with the mounting hole 361 through the third locking portion, and a second end of the third channel 430 forms a channel sealed from the outside between the first end of the second channel.

[0084] For example, as shown in FIG. 6, the instrument adapter 200 is in the first angle, and the height difference between the instrument interface 210 and the medium input end 450 is H1+H3. When the instrument adapter 200 is rotated to the second angle, the height difference between the instrument interface 210 and the medium input end 450 is H2+H3. Since the first vertical distance H1 and the second vertical distance H2 are the same, the height difference between the instrument interface 210 and the medium input end 450 does not change due to the rotation of the instrument adapter 200, and there is no need to recompensate. Compared with the need to recompensate every time, the pressure detection efficiency can be improved.

[0085] The instrument joint 200 can be inserted into the mounting hole 361. Specifically, the instrument joint 200 gradually approaches the mounting hole 361 from a state of being separated from each other.

The first mounting position can be a region, and the connecting rod 220 is in sliding connection with the mounting hole 361. The instrument joint 200 is continuously inserted into the mounting hole 361 until the instrument joint 200 reaches the second mounting position of the mounting hole 361. At this time, the third locking structure is switched from the unlocking state to the locking state. At this time, the third locking structure locks the relative movement between the instrument joint 200 and the adapter block 360. The connecting rod 220 is in limiting connection with the mounting hole 361. At the same time, when the instrument joint 200 is in the second mounting position of the mounting hole 361, the positions of the first opening and the second opening correspond to each other, and the first opening and the second opening are in contact.
