[0035] The following is an explanation of the implementation of the present application by means of specific embodiments. People familiar with the art can easily understand other advantages and effects of the present application from the contents disclosed in this specification.

[0036] In the following description, with reference to the accompanying drawings, several embodiments of the present application are described. It should be understood that other embodiments may also be used, and mechanical composition, structure, electrical and operational changes may be made without departing from the spirit and scope of the present disclosure. The following detailed description should not be considered restrictive, and the scope of the embodiments of the present application is limited only by the claims of the published patents. The terms used here are only to describe specific embodiments and are not intended to limit the present application. Spatially related terms, such as "upper", "lower", "left", "right", "below", "below", "lower", "above", "upper", etc., may be used in the text to facilitate the description of the relationship between an element or feature shown in the figure and another element or feature.

[0037] Although the terms first, second, etc. are used to describe various elements in this article in some instances, these elements should not be limited by these terms. These terms are only used to distinguish one element from another element. For example, the first detection probe can be referred to as the second detection probe, and similarly, the second detection probe can be referred to as the first detection probe, without departing from the scope of the various described embodiments. The first detection probe and the second detection probe are both describing a certain detection probe, but unless the context clearly indicates otherwise, they are not the same detection probe. Similar situations also include the first latch and the second latch, the first locking assembly and the second locking assembly, the first stopper and the second stopper, the first limit area and the second limit area, etc.

[0038] In view of the technical problems mentioned in the background technology, the present application discloses a measuring device and a measuring equipment, which are provided by arranging a connecting element on a first detection probe, arranging a first locking assembly on a substrate, and realizing the installation or disassembly of the first detection probe on the substrate by clamping or releasing the first locking assembly and the connecting element, and at the same time ensuring the correct installation of the first detection probe on the substrate. By arranging a first latch connected to the first locking assembly, and realizing the clamping or release of the first locking assembly and the connecting element by switching the first latch between a locked position and an unlocked position. By arranging a first limiting member on the substrate, and a first limiting area with an opening toward the first latch, the first latch can be relatively moved into the first limiting area when in the locked position, so as to limit the movement of the first latch switching toward the unlocked position, thereby preventing the first detection probe from being separated from the substrate due to accidental touch by the measuring personnel, thereby ensuring the smooth progress of the measurement operation.

[0039] The measurement personnel mentioned in the above or subsequent embodiments of the present application may be, for example, personnel responsible for performing measurement work, for example, test engineers, equipment maintainers, quality controllers, or data collectors, etc. Of course, the measurement work may also be performed by a robot, and the present application does not limit this.

[0040] See also Figure 1 , which is a schematic diagram of the structure of a measuring device in one embodiment of the present application, as shown in the figure, the measuring device includes a base 1, an articulated arm 2, and a measuring device 3. The articulated arm 2 has a proximal end and a distal end opposite to each other, the proximal end of which is connected to the base 1, and the distal end of which is provided with the measuring device 3. It should be noted that, Figure 1 The measuring device shown is only an exemplary description. In other examples, the measuring device may also be configured to include other structures or be composed of other structures. The measuring device may also be a three-dimensional coordinate measuring machine. In addition, in the subsequent embodiments, in order to clearly illustrate the relative positions of various parts, structures, assemblies, mechanisms, components, equipment, or devices in the measuring device, the proximal end and the distal end of the articulated arm are used as the reference for distinction. The side of each part, structure, assembly, mechanism, component, equipment, or device that is relatively close to the proximal end of the articulated arm is called the proximal end (also called the proximal side), and the side that is relatively close to the distal end of the articulated arm is called the distal end (also called the distal side).

[0041] like Figure 1As shown, the base 1 is used to be installed on a measuring platform, so that the base 1 can be used as a connecting part so that the articulated arm 2 can rotate in space with the measuring platform as the base point, so that the measuring device 3 can be freely oriented in space and positioned near the object to be measured or positioned in contact with the object to be measured for measurement. In one example, the base 1 may include a mounting device 10, and the mounting device 10 allows the measuring device to be removably set on the measuring platform, and the measuring platform is, for example, an inspection table, a processing platform, a wall, a ground, or a tripod. For example, the mounting device 10 can be configured as a threaded ring structure, and the measuring device can be placed on the measuring platform for measurement by tightening the threaded ring structure on the measuring platform, and the measuring device can be removed from the measuring platform or the direction of the measuring device can be adjusted by loosening the threaded ring structure on the measuring platform. Furthermore, an operating part can be configured on the threaded ring structure to facilitate tightening or loosening operations.

[0042] In one embodiment, the articulated arm 2 provides the measuring device 3 with the freedom to move in space, so that the measuring device 3 can move to align with the point to be measured for measurement. The point to be measured corresponds to the position or area to be measured on the object to be measured, and aligning with the point to be measured means that the position of the measuring device 3 can measure the point to be measured.

[0043] In one embodiment, if Figure 1 As shown, the articulated arm 2 includes a first arm component 20, a second arm component 21, and seven shaft assemblies, each of which can provide rotary rotation or hinge rotation. Figure 1The seven axis components are respectively the first axis component 22, the second axis component 23, the third axis component 24, the fourth axis component 25, the fifth axis component 26, the sixth axis component 27, and the seventh axis component 28. The first axis component 22 is connected to the base 1, and provides a rotary rotation around the axis of the base 1 as the center. The second axis component 23 is connected to the proximal end of the first arm component 20 and connected to the first axis component 22. The second axis component 23 provides a hinge rotation around an axis perpendicular to the first arm component 20 (which may correspond to the axis of the second axis component). The third axis component 24 is connected to the distal end of the first arm component 20, and provides a rotary rotation around the axis of the first arm component 20 as the center. The fourth axis component 25 is connected to the proximal end of the second arm component 21 and connected to the third axis component 24. The fourth axis component 25 provides a hinge rotation around an axis perpendicular to the second arm component 21 (which may correspond to the axis of the fourth axis component 25). The fifth axis assembly 26 is connected to the distal end of the second arm member 21, and provides a rotational rotation centered on the axis of the second arm member 21. The sixth axis assembly 27 is connected to the proximal end of the second arm member 21 and is connected to the fifth axis assembly 26. The sixth axis assembly 27 provides a hinged rotation around an axis perpendicular to the second arm member 21 (which may correspond to the axis of the sixth axis assembly 27). The seventh axis assembly 28 is connected to the sixth axis assembly 27 and is further connected to the measuring device 3, and provides a rotational rotation centered on the axis of the measuring device 3.

[0044] In some embodiments, the axis assemblies (e.g., the first axis assembly 22 and the second axis assembly 23) that are combined together to connect the first arm member 20 to the base 1 are collectively referred to as the first joint mechanism. Similarly, the axis assemblies (e.g., the third axis assembly 24 and the fourth axis assembly 25) that are combined together to connect the first arm member 20 to the second arm member 21 are collectively referred to as the second joint mechanism. The axis assemblies (e.g., the fifth axis assembly 26, the sixth axis assembly 27, and the seventh axis assembly 28) that are combined together to connect the measuring device 3 to the second arm member 21 are collectively referred to as the third joint mechanism. In some embodiments, the positions of the axis assemblies and the number of axis assemblies included in each joint mechanism may also be different from those in FIG. Figure 1 Different from what is shown in the figure, for example, the third axis assembly 24 can be moved to the proximal end of the first arm member 20, and together with the first axis assembly 22 and the second axis assembly 23, serve as the first joint mechanism, and the fourth axis assembly 25 serves as the second joint mechanism. Of course, the axis assemblies can also be combined in other ways, which will not be described in detail here.

[0045] like Figure 1 In the embodiment shown, the articulated arm 2 is provided with seven axis assemblies to provide seven axis rotations. Figure 1The measuring device in the illustrated embodiment is called a seven-axis coordinate measuring machine. In some embodiments, the seventh axis assembly may not be included, in which case the measuring device provided with six axis assemblies to provide six-axis rotation is called a six-axis coordinate measuring machine.

[0046] It should be understood that Figure 1 The configuration of two arm components and seven axis assemblies in the middle articulated arm is merely an exemplary description, and the present application is not limited thereto. The articulated arm can be configured with any number of arm components, and the axis assemblies connecting adjacent arm components, arm components and bases, or arm components and measuring devices can also be configured with any number. The articulated arm can provide more or less than six-axis or seven-axis rotation, as long as the articulated arm includes at least one arm component connected to the base and an axis assembly connected between the base and the arm component to provide hinged rotation.

[0047] In one embodiment, the arm component in the articulated arm may be configured as an elongated cylindrical shape and may be made of a suitable rigid material, for example, a lightweight and high-strength metal alloy such as an aluminum alloy, a magnesium alloy, or a carbon composite material.

[0048] In one embodiment, each axis assembly includes an encoder, which can be configured as an angle encoder, which can provide rotation information of the corresponding axis assembly, so that the rotation information provided by the encoders of all axis assemblies can determine the position of the measuring device relative to the base. Further, the main control device configured in the base can determine the three-dimensional coordinates of the point to be measured based on the position of the measuring device relative to the base and the acquired position data.

[0049] See also Figures 1 to 3 ,in, Figure 2 It is a schematic diagram of the structure of a measuring device in one embodiment of the present application. Figure 3 The diagram shows a schematic diagram of the disassembled structure of a measuring device in one embodiment of the present application. Figures 1 to 3 As shown, the measuring device 3 includes a base 30 and a detection probe 31. The detection probe 31 is detachably connected to the base 30. The base 30 is connected to the distal end of the articulated arm 2. Figure 1 The seventh shaft assembly 28 is connected to the shaft assembly 28. It should be noted that: Figure 1 The example in which the measuring device is connected to the articulated arm is used for schematic illustration. However, in other embodiments, the measuring device may also be connected to other components or used alone, and the present application does not impose any limitation on this.

[0050] In one embodiment, an interface unit is disposed on the base 30. For example, the interface unit may be configured to include a trigger component interface module and a probe interface module. The trigger component interface module is used to connect a trigger component, which may be, for example, Figure 1The handle 34 shown may also be a keypad, and as shown in the figure, the trigger component is configured as a pistol-grip style handle 34. In some examples, the handle is configured with a plurality of grooves, and the measurement personnel can pass their fingers through the grooves and further manipulate the handle to move the measurement device toward the object to be measured.

[0051] The probe interface module is configured as at least one, and is used to install at least one detection probe, and the detection probe is used to measure the object to be measured. In one embodiment, the probe interface module is configured as one, that is, one detection probe can be configured on the substrate 30. In one embodiment, Figure 3 As shown, the probe interface module is configured as two, wherein the first probe interface module 32 can be configured at the front end or front of the base 30, and the second probe interface module 33 can be configured at the side of the base 30. In this embodiment, the probe interface module is configured as two (32, 33), which can allow for detachable connection of one or two detection probes. In one example, the probe interface module can allow for detachable connection of a detection probe, for example, the detection probe 31 can be selectively connected to the first probe interface module 32 or to the second probe interface module 33. For example, as Figure 3 As shown, when the detection probe 31 is connected to the first probe interface module 32, the second probe interface module 33 is in an idle state. To avoid affecting its internal structure, a cover 330 can be configured thereon to cover its internal structure. In another example, the probe interface module can allow two detection probes to be detachably connected. For ease of description, the two detection probes are referred to as the first detection probe and the second detection probe, wherein the first detection probe can be, for example, the detection probe 31, and it is also described as the first detection probe 31 in the subsequent embodiments, which should not be understood as a limitation of the present application. In this example, the first detection probe 31 can be connected to the first probe interface module 32, and the second detection probe can be connected to the second probe interface module 33. Of course, the first detection probe 31 can be connected to the second probe interface module 33, and the second detection probe can be connected to the first probe interface module 32.

[0052] In one embodiment, the detection probe may be configured as a contact detection probe. The contact detection probe may be configured as Figures 1 to 3The ball probe shown can also be configured as a touch-sensitive, curved, or extended probe, etc. The present application does not limit the type of contact detection probe. In one embodiment, the detection probe is configured as a non-contact scanner, and the non-contact scanner can measure the object to be measured in a non-contact manner, so that contact damage will not be caused to the object to be measured. Specifically, the non-contact scanner may include a light source (such as a laser) and an optical sensor (such as a camera), and the data of the object to be measured can be obtained by a triangulation method. The following is described by taking the first detection probe 31 as a contact detection probe and the second detection probe as a non-contact scanner as an example, but it should be understood that the present application does not limit the types of the first detection probe and the second detection probe, and those skilled in the art may also set the first detection probe and the second detection probe to contact detection probe or non-contact scanner, or configure the first detection probe to a non-contact scanner, and the second detection probe to a contact detection probe.

[0053] In order to realize the detachable connection between the first detection probe 31 and the base body 30, in one embodiment, as shown in FIG. Figure 3 As shown, the first detection probe 31 includes a first connecting element 311, such as Figure 2 As shown, the base 30 is provided with a first locking assembly and a first latch 36 connected to the first locking assembly, and the first latch 36 is used to switch between a locking position and an unlocking position so that the first locking assembly clamps or releases the first connecting element 311. In this embodiment, the first detection probe 31 is clamped by the first locking assembly 35 to be fixed to the front end of the base 30. It should be understood that the front end refers to the side of the base 30 facing the first probe interface module 32.

[0054] It should be noted that the locked position refers to the position of the first latch when the first detection probe is locked to the base. When the first latch is in the locked position, the first locking assembly clamps the first connecting element so that it cannot be pulled out of the base. The unlocked position refers to the position of the first latch when the first detection probe can be detached from the base. When the first latch is in the unlocked position, the first locking assembly can release the first connecting element so that it can be pulled out of the base.

[0055] In one embodiment, see Figures 4 to 7 , Figure 4 Display as Figure 2 A partial cross-sectional view of the measuring device in the embodiment shown, Figure 5 Display as Figure 3 A partial cross-sectional view of the measuring device in the embodiment shown, Figure 6 Display as Figure 4 The measuring device in the embodiment shown is a partially enlarged schematic diagram of the first locking assembly portion. Figure 7The diagram is a schematic diagram showing a first locking assembly locking a first connecting element in one embodiment of the present application. Figures 4 to 7 As shown, the first locking assembly 35 includes a lock body 351, two clamps 352, and a connecting rod 353. The lock body 351 has a channel 354 that allows the first connecting element 311 to enter or leave, and the two clamps 352 are symmetrically arranged on both sides of the channel 354. The connecting rod 353 is connected to the first latch and linked with the two clamps 352 to drive the two clamps 352 to move relative to each other under the action of the first latch, so that the two clamps 352 enter the channel 354 to lock the first connecting element or exit the channel 354 to release the first connecting element. Specifically, the connecting rod 353 may include a rod portion and a rod connecting portion connected to the rod portion, and the first latch 36 may be connected to the rod connecting portion to achieve connection with the connecting rod 353, and the rod portion is associated with the two clamps 352. By actuating the first latch 36, the two clamps 352 are driven.

[0056] In one embodiment, if Figure 6 As shown, the lock body 351 is arranged inside the base 30. Further, it can be arranged at the front end of the base so as to fix the first detection probe 31 to the front end of the base. In the present embodiment, the channel 354 of the lock body 351 is located at the central position of the lock body 351. The lock body 351 is provided with two grooves located on both sides of the channel 354 and connected with the channel 354. The two clamping members 352 are respectively arranged in the two grooves. Matchingly, the first connecting element 311 has two recesses arranged relatively to each other, and the two recesses can be respectively engaged with the two clamping members 352 to achieve the locking of the first connecting element 311. For example, when the two clamping members 352 are relatively close to each other in the two grooves and enter the channel 354, they engage with the two recesses on the first connecting element 311 to form a structure as shown in the figure. Figure 7 When the two clamping members 352 move away from each other in the two grooves and leave the channel 354 , they also move away from the two recesses of the first connecting element 311 , so that the first connecting element 311 can be pulled out of the channel 354 .

[0057] In one embodiment, the first locking assembly can be configured as an electromagnetic lock to achieve locking or releasing of the first connecting element. Matchingly, a coil and a magnet are configured in the first connecting element. When the first connecting element needs to be locked, a current is passed through the coil to generate a magnetic field, and the first locking assembly can lock the first connecting element under the action of the magnetic force. When the first connecting element needs to be released, the current is cut off to make the magnetic field disappear or a current in the opposite direction is passed through the coil to change the direction of the magnetic force to achieve the release of the first connecting element.

[0058] As described in the previous embodiment, the first locking assembly can clamp or release the first connecting element by switching the first latch between the locked position and the unlocked position. Further, the first latch can switch between the locked position and the unlocked position by rotation. Figure 2 and Figure 8 The method of cooperating the first latch with the first locking assembly to release or clamp the first connecting element is described, wherein: Figure 8 The diagram shows a state in which the first lock latch is in an unlocked position in one embodiment of the present application. Figure 8 In the diagram, the first latch 36 is located in a direction perpendicular to the base 30, which is the unlocked position. In this position, the first locking assembly is as shown in FIG. Figure 6 In the state shown in FIG. 1 , the first connecting element 311 can be withdrawn from the channel, thereby realizing the detachment of the first detection probe 31 from the substrate 30, as shown in FIG. Figure 8 When the first detection probe 31 needs to be connected to the base 30, the first latch 36 can be placed in the following manner: Figure 8 The first detection probe 31 is inserted into the channel 354 of the first locking assembly 35 in the unlocked position shown in FIG. 1 , and then the first locking latch 36 can be rotated to switch it to the locked position, as shown in FIG. Figure 2 As shown, in this position, the first locking assembly 35 is as shown in FIG. Figure 7 The status indicated.

[0059] In order to realize the rotational movement of the first latch, in one embodiment, refer to Fig. 9 , which is a schematic diagram of the split structure of the first latch in one embodiment of the present application. Fig. 9 As shown, the first latch 36 has a fixed end 361 and a free end 362, and the fixed end 361 is formed with a mounting portion 3611. By configuring a shaft assembly 3612 to pass through the mounting portion 3611 and connect with the base 30, the first latch 36 rotates around the shaft assembly 3612 as the axis, thereby realizing the switching of the first latch 36 between the locked position and the unlocked position. Further, the first latch 36 is connected to the connecting rod in the first locking assembly through a connecting portion 3613, and the shaft assembly 3612 passes through the mounting portion 3611 and is fixed on the connecting portion 3613 so that the first latch 36 is fixedly connected to the connecting portion 3613, so that the connecting portion 3613 can be driven to rotate by rotating the first latch 36, and further the connecting rod drives the clamping member to clamp or release the first connecting element 311.

[0060] In order to restrict the first latch to Figure 2 The locked position shown is Figure 2As shown, a stopper 37 is formed on the base 30, and the stopper 37 is used to limit the locking position. In one example, the stopper 37 is used to limit the locking position and can indicate the locking position to prevent the first latch 36 from not rotating into place when the measurement personnel uses the first latch to lock the first detection probe. For example, when the measurement personnel rotates the first latch 36 to a position that abuts the stopper 37, the resistance generated can prompt the measurement personnel that the first latch 36 has been rotated to the locking position. In one example, the stopper 37 is used to limit the locking position and can hinder the first latch 36 from over-moving beyond the locking position. Specifically, when the first latch 36 is rotated from Figure 8 Turn counterclockwise to the unlocked position shown. Figure 2 In the locked position shown in FIG. 1 , the first locking assembly locks the first connecting element. At this time, if the stopper 37 is not provided, the first latch 36 will be Figure 2 The locked position shown is further rotated counterclockwise, thereby causing the first locking assembly to release the first connecting element again.

[0061] In one embodiment, the stopper 37 is configured as a protrusion extending from the base, which is located on the moving path of the first latch 36. Figure 8 The stopper 37 can be configured as an "L"-shaped protrusion, which surrounds the upper and right sides of the first latch 36. To avoid scratching the measurement personnel, the edge of the stopper 37 facing the first latch 36 is configured as a curved edge. The structure of the stopper 37 is not limited to this. In other embodiments, the stopper can be configured as a long strip structure located on the upper side of the first latch, as long as it can prevent the first latch from moving too much.

[0062] During the measurement operation, the first latch 36 needs to be Figure 2 The first detection probe 31 can be clamped on the base 30 only when the first detection probe 31 is in the locked position shown. However, the first latch 36 may be moved away from the locked position due to accidental touch, inadequate locking position, or natural drooping, further causing the first detection probe to be detached from the base. In view of this, in one embodiment, Figure 2 As shown, a first limiting member 38 is provided on the base 30, and the first limiting member 38 has a first limiting area with an opening toward the first latch 36. When the first latch 36 is in the locked position, it can move relatively into the first limiting area 381 to limit the movement of the first latch 36 toward the unlocked position.

[0063] Specifically, see Fig.10 and Fig.11 , Fig.10 The diagram is a schematic diagram of a state before the first latch enters the first limiting area in one embodiment of the present application. Fig.11The diagram is a schematic diagram of a state in which the first latch enters the first limiting area in one embodiment of the present application. Fig.10 As shown, the opening of the first limiting area 381 faces the first latch 36, and its width is adapted to the first latch 36, so that the first latch 36 is located Figure 2 When the locking position is shown, the first limit area 381 can be further entered to form Fig.11 At this time, under the restriction of the first stopper 38, the first latch 36 can be restricted to move toward Figure 8 The movement for switching to the unlocked position is shown.

[0064] In order to achieve the relative movement of the first latch 36 in the first limiting area 381, in one embodiment, refer to Fig.12 , displayed as Fig. 9 A partial enlarged schematic diagram of a portion of the mounting portion of the first latch in the illustrated embodiment. As shown in the figure, the mounting portion 3611 provides an activity space 36111 for the shaft assembly 3612, and the activity space 36111 allows the mounting portion 3611 to move relative to the shaft assembly 3612 so that the first latch 36 can move into or out of the first limiting area 381.

[0065] exist Fig.12 In the illustrated embodiment, the movable space 36111 is configured as a through hole on the mounting portion 3611, and the shaft assembly 3612 includes a head and a tail. The shape of the through hole is, for example, a runway shape, and the short diameter of the through hole is adapted to the tail diameter of the shaft assembly 3612 and is smaller than the diameter of the head of the shaft assembly 3612, so that the mounting portion 3611 can fix the first latch 36 on the base 30. At the same time, the long diameter of the through hole is larger than the tail diameter of the shaft assembly 3612, so that the mounting portion 3611 can move relative to the shaft assembly 3612 through the movable space 36111, thereby allowing the first latch 36 to enter or leave the first limiting area 381. For example, when the first latch 36 is located Fig.11 In the state shown, the measurement personnel pulls the first latch 36 to the right, so that the mounting portion 3611 moves to the right relative to the shaft assembly 3612 through the active space 36111, thereby causing the first latch 36 to leave the first limiting area 381, forming Fig.10 When the first latch 36 is in the Fig.10 In the state shown, the measurement personnel pulls the first latch 36 to the left, so that the mounting portion 3611 moves to the left through the activity space 36111, and then the first latch 36 enters the first limiting area 381, forming Fig.11 Status shown.

[0066] In order to limit the depth of the first latch 36 entering the first limiting area 381, in one embodiment, the active space 36111 limits the moving distance of the first latch 36, and the movement of the first latch 36 into the first limiting area 381 stops when the shaft assembly 3612 moves relatively to the end of the active space 36111. Fig.11 As shown, the terminal refers to the end of the movable space 36111 opposite to the first limit member 38. When the shaft assembly 3612 moves relatively to the terminal, the movement of the first latch 36 into the first limit area 381 stops. At this time, the long diameter of the movable space 36111 should be configured in a suitable range so that the first latch 36 enters the first limit area 381 to an appropriate depth. Specifically, it should be determined according to specific production needs. As long as the first latch can enter the first limit area and limit its movement to the unlocking position, the present application does not impose any restrictions on this.

[0067] After the first latch 36 moves into the first limiting area 381, in order to achieve the locking of the first latch 36, in one embodiment, as shown in FIG. Fig.12 As shown, the mounting portion 3611 includes an edge portion 36112 that forms a movable space 36111, and the side of the edge portion 36112 away from the first limiting member 38 has a protruding structure 36113 toward the head of the shaft assembly 3612. When the first latch 36 moves into the first limiting area 381, the head of the shaft assembly 3612 presses against the protruding structure 36113 to lock the first latch 36.

[0068] In one embodiment, the edge portion 36112 is configured as the outer edge of the activity space 36111. For example, in an example where the activity space 36111 is configured as a through hole and the hole is in a racetrack shape, the edge portion 36112 is also in a racetrack shape. Fig.12 In the illustrated embodiment, the height of the edge portion 36112 is lower than the surface of the first latch 36, so that the mounting portion 3611 forms a recess on the first latch 36, and the edge portion 36112 can provide support for the head of the shaft assembly 3612 while also positioning the head in the recess, thereby preventing the head from protruding from the surface of the first latch 36 and occupying external space.

[0069] The following combination Fig.10 and Fig.11The locking effect of the protruding structure 36113 on the first latch 36 is described. When the shaft assembly 3612 moves relatively to the protruding structure 36113, the cooperation between the shaft assembly 3612 and the edge portion 36112 will enter a relatively squeezed state from a relatively loose state, so as to produce an effect similar to an interference fit. That is, when the shaft assembly 3612 and the edge portion 36112 are in a relatively squeezed state, the measurement personnel need to apply a large force to the first latch 36 to make the shaft assembly 3612 leave the protruding structure 36113, and then realize the switching of the first latch 36 from the locked position to the unlocked position.

[0070] In order to provide buffering for the shaft assembly and the edge portion, in one embodiment, a gasket is arranged at the position where the shaft assembly 3612 contacts the edge portion 36112. The material of the gasket includes but is not limited to plastic and rubber. The plastic may be, for example, nylon, polypropylene, polytetrafluoroethylene, etc., and the rubber may be, for example, nitrile, silicone, etc. As long as it can prevent the shaft assembly 3612 from directly contacting the edge portion 36112 and evenly disperse the force between the two to avoid damage to the edge portion due to excessive local stress, it will be sufficient.

[0071] In order to facilitate the measurement personnel to operate the first latch, in one embodiment, Fig. 9 As shown, an operating portion 3621 for the measurement personnel to grasp is formed on the free end 362 of the first latch 36. The operating portion 3621 provides a force application position for the measurement personnel, that is, the measurement personnel can operate the first latch 36 by operating the operating portion 3621, for example, rotating the first latch between the unlocked position and the locked position, and relatively moving the first latch into or out of the first limit area, etc., which operations require contacting the first latch. Fig. 9 In the illustrated embodiment, in order to save the measurement personnel more effort, the operating portion 3621 is located on the side of the first latch 36 away from the first stopper 38, and is configured as a protruding structure, through which the measurement personnel can operate the first latch 36. For example, the measurement personnel's thumb contacts the protruding structure, thereby exerting a force on the first latch 36 to operate the first latch 36. In this embodiment, the height and size of the operating portion 3612 can be designed and arranged according to ergonomics and actual application requirements to ensure the efficiency and comfort of the measurement personnel during operation, and this application does not impose any restrictions on this.

[0072] In some other embodiments, the operating portion 3612 may also be configured on the first latch in other forms, for example, it may be configured as a recessed structure, and the measurement personnel's finger may be placed in the recessed structure to operate the first latch. Of course, the operating portion 3612 may not be provided, that is, the measurement personnel may operate directly on the first latch 36.

[0073] like Figure 3As shown, in order to realize the detachable connection between the second detection probe and the base 30, in one embodiment, refer to Fig.13 , displayed as Figure 3 A partial cross-sectional view of the measuring device in the illustrated embodiment, as shown in the figure, a second locking assembly 45 and a second latch 46 are arranged on the base 30, the second latch 46 is connected to the second locking assembly 45, and the second latch 46 is used to switch between a locked position and an unlocked position so that the second locking assembly 45 clamps or releases the second connecting element of the second detection probe.

[0074] The second connecting element of the second detection probe can be configured in the same manner as the first connecting element 311 on the first detection probe 31, which will not be described in detail here. In this embodiment, the second detection probe is clamped to one side of the base 30 by the second locking assembly 45. At this time, the second locking assembly 45 can be arranged along the circumference of the base 30, located at the rear end of the first locking assembly 35, and perpendicular to the first locking assembly 35. Fig.13 In the illustrated embodiment, the second locking assembly 45 includes a lock body 451, two clamping members 452, and a connecting rod 453. The lock body 451 has a channel 454. Its specific structure and function are the same as those of the first locking assembly 35. Please refer to the above description and will not be repeated here. Of course, the configuration of the second locking assembly 45 may also be different from that of the first locking assembly 35, which is determined according to actual application requirements, and this application does not limit this.

[0075] Present as Figure 2 and Figure 3 As shown, the second latch 46 is disposed on the other side opposite to the first latch 36, and Figure 3 The state shown is the locked position of the second latch 46. The unlocked position may be, for example, a position where the second latch 46 is perpendicular to the base 30 (not shown). Figure 3 When the locked position is rotated 90° clockwise to the unlocked position, the two clamping members 452 are relatively close to each other and enter the channel 454, and at the same time engage with the second connecting element on the second detection probe to lock the second connecting element. Figure 3 In the locked position shown, the two clamping members 452 move away from each other and leave the channel 454, while releasing the second connecting element on the second detection probe.

[0076] In order to prevent the second detection probe from being separated from the substrate by accidental contact by the measurement personnel, in one embodiment, refer to Fig.14, which is a schematic diagram of the structure of the second latch in one embodiment of the present application. As shown in the figure, the base 30 is also provided with a second limiter 48, and the second limiter 48 has a second limiter area 481 opening toward the second latch 46. When the second latch 46 is in the locked position, it can relatively move into the second limiter area 481 to limit the movement of the second latch 481 switching toward the unlocked position. The second limiter 48 and the second limiter area 481 are respectively configured the same as the first limiter 38 and the first limiter area 381. Please refer to the previous description for their specific structure and function, which will not be repeated here.

[0077] In summary, in order to overcome the technical problems in the related art that the detection probe is not installed properly and is easily separated from the measurement device during the measurement process, the measurement operation cannot be carried out smoothly, the measurement device and the measuring equipment provided by the present application are provided by arranging a connecting element on the first detection probe, arranging a first locking assembly on the substrate, and realizing the installation or disassembly of the first detection probe on the substrate by clamping or releasing the first locking assembly and the connection element, and ensuring the correct installation of the first detection probe on the substrate. By arranging a first latch connected to the first locking assembly, and realizing the clamping or release of the first locking assembly and the connection element by switching the first latch between the locked position and the unlocked position. By arranging a first limiting member on the substrate, and a first limiting area with an opening toward the first latch, the first latch can be relatively moved into the first limiting area when in the locked position to limit the movement of the first latch switching toward the unlocked position, thereby preventing the first detection probe from being separated from the substrate, thereby ensuring the smooth progress of the measurement operation.
