[0032] 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.

[0033] 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.

[0034] Although the terms first, second, etc. are used to describe various elements 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 shaft assembly can be referred to as the second shaft assembly, and similarly, the second shaft assembly can be referred to as the first shaft assembly without departing from the scope of the various described embodiments. The first shaft assembly and the second shaft assembly are both describing a certain shaft assembly, but unless the context clearly indicates otherwise, they are not the same arm member. Similar situations also include the first arm member and the second arm member, the first recess and the second recess, the first rod and the second rod, etc.

[0035] In view of the technical problems mentioned in the background technology, the present application discloses a measuring device, which comprises a storage space and a handle mechanism that are adapted to each other and is arranged on a base. The handle mechanism is stored in the storage space so as not to occupy the working space of the measuring device. In addition, the handle mechanism can be extended from the storage space to present a state to be operated, so that when the measuring device needs to be transferred or adjusted, the handle mechanism can be convenient for the operator to use.

[0036] The operator mentioned in the above or subsequent embodiments of the present application may refer to a person or machine operating a measuring device. The person may be, for example, a person responsible for performing the measurement work, for example, a test engineer, an equipment maintainer, a quality controller, or a data collector. The machine may, for example, include a robotic arm. The subsequent embodiments are described by taking the operator as an operator as an example, which should not be construed as a limitation of the present application.

[0037] The ready-to-operate state refers to the state of the handle mechanism when the operator can operate, move or adjust the measuring device by holding the handle mechanism disposed on the base (in the form of Figure 4 The hidden state refers to a state in which the handle mechanism is retracted into the base and visually integrated with the base, so that the operator cannot manipulate the handle mechanism to operate, move or adjust the measuring device (as shown in FIG. Figure 1 state of the handle mechanism shown).

[0038] 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 an articulated arm 1, a measuring device 2, and a base 3. The articulated arm 1 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 2. 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).

[0039] In one embodiment, the articulated arm 1 provides the measuring device 2 with the freedom to move in space, so that the measuring device 2 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 2 can measure the point to be measured.

[0040] In one embodiment, if Figure 1 As shown, the articulated arm 1 includes a first arm component 10, a second arm component 11, and six shaft assemblies, each of which can provide rotary rotation or hinge rotation. Figure 1 The six axis components are respectively the first axis component 12, the second axis component 13, the third axis component 14, the fourth axis component 15, the fifth axis component 16, and the sixth axis component 17. The first axis component 12 is connected to the base 3, and provides a rotary rotation around the axis of the base 3 as the center. The second axis component 13 is connected to the proximal end of the first arm component 10 and connected to the first axis component 12. The second axis component 13 provides a hinge rotation around an axis perpendicular to the first arm component 10 (which may correspond to the axis of the second axis component). The third axis component 14 is connected to the distal end of the first arm component 10, and provides a rotary rotation around the axis of the first arm component 10 as the center. The fourth axis component 15 is connected to the proximal end of the second arm component 11 and connected to the third axis component 14. The fourth axis component 15 provides a hinge rotation around an axis perpendicular to the second arm component 11 (which may correspond to the axis of the fourth axis component 15). The fifth axis assembly 16 is connected to the distal end of the second arm component 11, and provides a rotational rotation centered on the axis of the second arm component 11. The sixth axis assembly 17 is connected to the proximal end of the second arm component 11 and is connected to the fifth axis assembly 16. The sixth axis assembly 17 provides a hinged rotation around an axis perpendicular to the second arm component 11 (which may correspond to the axis of the sixth axis assembly 17).

[0041] In some embodiments, the axis assemblies (e.g., the first axis assembly 12 and the second axis assembly 13) that are combined together to connect the first arm member 10 to the base 3 are collectively referred to as the first joint mechanism. Similarly, the axis assemblies (e.g., the third axis assembly 14 and the fourth axis assembly 15) that are combined together to connect the first arm member 10 to the second arm member 11 are collectively referred to as the second joint mechanism. The axis assemblies (e.g., the fifth axis assembly 16 and the sixth axis assembly 17) that are combined together to connect the measuring device 2 to the second arm member 11 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 14 can be moved to the proximal end of the first arm member 10, and together with the first axis assembly 12 and the second axis assembly 13, serve as the first joint mechanism, and the fourth axis assembly 15 serves as the second joint mechanism. Of course, other methods of combining the axis assemblies can also be used, which will not be described in detail here.

[0042] like Figure 1 In the embodiment shown, the articulated arm 1 is provided with six shaft assemblies to provide six axis rotations. Figure 1The measuring device in the illustrated embodiment is called a six-axis coordinate measuring machine. In some embodiments, it may further include a seventh axis assembly, which can provide a rotary rotation of the measuring device, and a measuring device provided with seven axis assemblies to provide a seven-axis rotation is also called a seven-axis coordinate measuring machine.

[0043] It should be understood that Figure 1 The configuration of two arm components and six 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 or seven axes of 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.

[0044] 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.

[0045] 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.

[0046] In one embodiment, the articulated arm may also be configured with at least one arm-end circuit for obtaining rotation information collected by an encoder connected thereto for transmission to the main control device. Taking a seven-axis articulated arm as an example, the articulated arm may be configured with three arm-end circuits, the first arm-end circuit being electrically connected to the encoders included in the second axis assembly and the third axis assembly, the second arm-end circuit being electrically connected to the encoders included in the fourth axis assembly and the fifth axis assembly, and the third arm-end circuit being electrically connected to the encoders included in the sixth axis assembly and the seventh axis assembly. Furthermore, the first to third arm-end circuits are electrically connected to the main control device, and the encoder included in the first axis assembly is electrically connected to the main control device, so that the main control device can obtain the rotation information of all encoders to further determine the position of the measuring device relative to the base.

[0047] In one embodiment, if Figure 1 As shown, the measuring device 2 includes a base 20 and a probe 21. The base 20 is connected to the distal end of the articulated arm 1. Figure 1The probe 21 is detachably mounted on the base 20. In some examples, the probe 21 is configured as a contact probe having different ends that can physically contact the object to be measured, including but not limited to a ball, touch-sensitive, curved, or extended probe. In some examples, the probe 21 is configured as a non-contact probe that can measure the object to be measured in a non-contact manner, so as not to cause contact damage to the object to be measured. The non-contact probe is, for example, a laser scanner, an optical sensor, an electrostatic sensor, etc.

[0048] Furthermore, an interface unit is configured on the base 20. The interface unit can be configured to include a probe interface module and a trigger component interface module. The probe interface module is configured to be at least one, and the probe 21 described in the above embodiment can be installed on the base 20 through a probe interface module. More probe interface modules can be used to connect other probes, including but not limited to laser scanning heads, fork-shaped probes, etc. The trigger component interface module is used to connect a trigger component, which can be, for example, a handle or a keypad.

[0049] During the measurement operation, the center of gravity of the articulated arm and the measuring device will change with the position of the measured point, thereby making the center of gravity of the measuring device unbalanced and causing the articulated arm to fall. In view of this, in one embodiment, the measuring device may further include a balancing mechanism, which is used to balance the change of the center of gravity torque of the articulated arm.

[0050] See also Figure 2 , which is a schematic diagram of the structure of a balancing mechanism in an embodiment of the present application, as shown in the figure, the balancing mechanism 4 is configured to include an outer support structure 41 and a balancing structure 42. The outer support structure 41 is configured on the peripheral side of an arm member connected to a base through at least one shaft assembly providing hinged rotation, so as to support the arm member during the rotation of the arm member around the shaft assembly, and the balancing structure 42 is sleeved on the shaft assembly and connected to the outer support structure, so that the outer support structure can drive the balancing structure to rotate during the rotation of the arm member to generate a torque force that balances the change of the center of gravity moment of the measuring device, so as to balance the center of gravity of the measuring device.

[0051] The structural design of the balancing mechanism shown in this embodiment enables the external support structure to bear the force of the balancing structure and further transfer it to the base, thereby avoiding the deflection deformation of the arm member of the measuring device. In addition, the balancing structure is sleeved on the shaft assembly corresponding to the arm member through its shaft sleeve assembly, and the balancing assembly of the balancing structure is sleeved on the shaft sleeve assembly and connected to the external support structure, so that the balancing structure is arranged around the shaft assembly and is convenient for disassembly and assembly. In this way, the balancing structure does not occupy the working space of the measuring device and is easy to be detached from the measuring device.

[0052] See also Figures 1 to 3 , Figure 3 The diagram shows a schematic diagram of a structure in which a balancing mechanism is configured on a measuring device in one embodiment of the present application. Figures 1 to 3 As shown, the outer support structure 41 included in the balancing mechanism 4 can be arranged on the peripheral side of the first arm component 10 , and the balancing structure 42 of the balancing mechanism 4 is connected to the base 3 and sleeved on the second shaft assembly 13 .

[0053] In one embodiment, if Figure 2 As shown, the outer support structure 41 includes an outer sleeve 411, an arm support portion 412, and a connecting assembly 413. Figure 1 and Figure 3 The connecting component 413 is connected between the outer sleeve 411 and the balancing structure 42 to achieve a fixed connection between the balancing structure 42 and the outer support structure 41. The outer sleeve 411 is non-contactly sleeved on the first arm member 10, and its proximal end is connected to the connecting component 413. The arm support part 412 is configured at the distal end of the outer sleeve 411. When the first arm member 10 is placed in the outer sleeve 411, the arm support part 412 supports the first arm member 10.

[0054] The outer sleeve 411 is non-contactly sleeved on the first arm component 10, that is, the outer sleeve 411 surrounds the first arm component 10 with a certain gap therebetween, and only the arm support portion 412 provides support for the first arm component 10. In this way, the outer sleeve 411 bears the torque provided by the balancing structure, and even if the outer sleeve 411 is deformed due to long-term stress, since it is not in contact with the first arm component 10, it will not affect the accuracy of the first arm component 10. Furthermore, the first arm component 10 can be configured to be relatively thin, and the outer sleeve 3111 can be configured to be relatively thick.

[0055] In order to avoid the axis of the first arm member 10 and the axis of the outer sleeve 411 being offset and affecting the measurement accuracy, in one embodiment, the arm support portion 412 supports the first arm member in a point support or line support manner. In some examples, the arm support portion 412 may include a coupling and a support member. The coupling member is adapted to the outer sleeve to be connected to the distal end of the outer sleeve, and the support member is configured on the side wall of the coupling member to support the first arm member 10 in a point support or line support manner. In some other examples, the coupling member and the outer sleeve may not be distinguished, that is, the arm support portion 412 may only include a support member, and the support member is arranged on the outer sleeve to support the first arm member.

[0056] For example, the support member may be configured as a roller, so that when the axis of the first arm member 10 deviates from the axis of the outer sleeve 411, it can slide relative to the roller to adjust the axis. The support member may also be configured as a long strip support. In this way, the axis of the first arm member can also be adjusted. Further, the support member may be configured as two, and the two support members may be distributed at 120 degrees, for example. Of course, the support member may also be configured as a plurality greater than two, such as three, four, five, etc.

[0057] In one embodiment, when the balancing structure 42 is sleeved on the second shaft assembly 13, there is a circumferential gap between the balancing structure 42 and the second shaft assembly 13. That is to say, the second shaft assembly 13 and the balancing structure 42 are not in contact with each other in the circumferential direction and are separable from each other. In this way, when the second shaft assembly 13 or the balancing structure 42 fails and needs to be replaced, the two can be separated more conveniently for separate replacement.

[0058] In one embodiment, if Figure 2 As shown, the balancing structure 42 includes a balancing component 421, a sleeve component 422 and a mounting component 423. The sleeve component 422 is sleeved on the second shaft component and fixed on the mounting component 423, and the balancing component 421 is sleeved on the sleeve component 422 and fixedly connected to the outer support structure 41, so that the outer support structure 41 supports the first arm component to rotate and drives the balancing component 421 to rotate around the sleeve component 422 to generate torque force, so that the center of gravity of the measuring device is balanced. In other words, the rotation of the balancing component 421 around the second shaft component will generate a torque force that balances the change in the center of gravity moment of the measuring device. Further, during the measurement work, the position of the articulated arm and the measuring device will change in space, thereby causing the center of gravity moment of the measuring device to change. Therefore, balancing the change in the center of gravity moment of the measuring device is to balance the change in the center of gravity moment caused by the change in the position of the articulated arm and the measuring device in space, so that the articulated arm and the measuring device can be balanced and will not fall.

[0059] In one embodiment, the sleeve assembly 422 includes a mandrel, which is configured as a ring-shaped structure that penetrates front and back to be sleeved on the second shaft assembly. The sleeve assembly 422 may further include a mandrel fixing ring, which is connected to the mounting assembly 423, and a fixing member is provided to pass through the mandrel fixing ring and be connected to the end surface of the mandrel, thereby fixing the mandrel.

[0060] In one embodiment, the balancing assembly 421 includes a torsion spring and a rotating connection part, wherein the torsion spring is sleeved with a shaft sleeve assembly 422 and has a fixed end and a follower end. The rotating connection part is fixedly connected to the follower end of the torsion spring and is fixedly connected to the outer support structure 41 to adjust the torque of the torsion spring during the rotation of the outer support structure 41 so that the center of gravity of the measuring device is balanced.

[0061] In one embodiment, the mounting assembly 423 includes a bearing structure and a connecting bracket. The bearing structure is connected to the base, and the connecting bracket is arranged on the bearing structure and supports or connects the sleeve assembly 422 and the balancing assembly 421, thereby ensuring that the sleeve assembly 422 and the balancing assembly 421 can rotate around the axis of the base without hindering the rotation generated by the first shaft assembly.

[0062] like Figure 2 and Figure 3 The balancing mechanism described in any embodiment is only an example. In other embodiments, the balancing mechanism may also be configured to include a self-balancing structure. The self-balancing structure may be configured as follows: Figure 1 The second axis assembly 13 of the measuring device shown is connected to the first arm member 10 to balance the gravity torque change of the joint arm. The present application does not limit whether the measuring device has a balancing mechanism, and the configuration or structure of the balancing mechanism.

[0063] like Figure 1 and Figure 3 As shown, the base 3 is used to be installed on a measuring platform. In this way, the base 3 can be used as a connecting part so that the articulated arm 1 can rotate in space with the measuring platform as the base point, so that the measuring device 2 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 3 may include a mounting device 30, and the mounting device 30 allows the measuring device to be removably arranged 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 30 can be configured as a threaded ring structure, and the measuring device is 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. Further, an operating part can be configured on the threaded ring structure to facilitate tightening or loosening operations.

[0064] In one embodiment, if Figure 3 As shown, the base 3 includes a shell 34, and the shell 34 encloses the device, assembly or component located inside the base 3. In order to provide a certain rigidity while reducing the overall weight of the measuring device, in one example, the shell 34 is made of high-strength plastic.

[0065] See also Figure 4 and Figure 5 Combined with Figure 3 , Figure 4 It is a schematic diagram showing the structure of the base of the handle mechanism in an operation-ready state in one embodiment of the present application. Figure 5 The schematic diagram of the structure of the handle mechanism and the base being separated in one embodiment of the present application is shown as follows: Figures 3 to 5 As shown, the base 3 is provided with a storage space 31 and a handle mechanism 32, and the handle mechanism 32 can be stored in the storage space 31 (shown as Figure 3 The state shown in FIG. 1 may also be extended from the storage space 31 to present a state ready for operation (shown as FIG. Figure 4 status shown in ).

[0066] In one embodiment, if Figure 4 As shown, a key operation area 33 is provided on the base 3, and the handle mechanism 32 is located on one side of the key operation area 33 and is configured on the upper side of the key operation area 33. The key operation area 33 is used to operate, control and monitor the real-time status of the measuring device performing the measuring operation. It should be understood that arranging the handle mechanism 32 on one side of the key operation area 33 is more conducive to the operator's installation of the measuring device, as well as the transfer or adjustment operation during the test operation.

[0067] In one embodiment, a button 331 is configured on the button operation area 33, which is used to operate the measuring device to perform a specific function. For example, the button 331 can be a switch button for starting or shutting down the measuring device, an emergency stop button for stopping the measurement operation in an emergency, a fault diagnosis button for starting the self-test program of the measuring device, or a program selection button for performing a specific task, but it is not limited to this, and it depends on the needs of the user and the design of the manufacturer. Of course, the number of the buttons can be one or more, and this application does not limit this.

[0068] In one embodiment, a user interface may also be configured on the key operation area 33. Furthermore, the main control device described in the above embodiment may also be electrically connected to the keys or user interface in the key operation area. A processor may also be configured in the key operation area 33. The processor is used to be electrically connected to the main control device, the keys, and the user interface to receive or forward information to the main control device, or to send information provided by the main control device to the user via the user interface.

[0069] exist Figure 5 In the embodiment shown, the storage space 31 has an opening 311, and the opening 311 is formed on the shell 34 of the base 3, and the handle mechanism 32 can be pulled out from the opening 311 to extend out of the storage space 31. For example, the opening 311 can be formed on the peripheral side or upper side of the shell 34, and can also be formed at the edge of the shell 34 to serve as a part of the outer contour of the shell. When the handle mechanism 32 extends out of the storage space 31, it protrudes from the shell 34 of the base 3 to form a Figure 4 The illustrated state is ready for operation, so that the operator can conveniently hold the handle mechanism 32 by hand.

[0070] Furthermore, when the handle mechanism 32 is stored in the storage space 31, the opening 311 is closed in a complementary manner to the opening 311. That is, when the handle mechanism 32 is in the storage space 31, Figure 3 In the hidden state shown, the handle mechanism 32 has an outer contour adapted to the opening 311, so that the handle mechanism 311 can be spatially aligned with the opening 311, thereby closing the opening 311. It is understandable that when the opening 311 is closed, the internal structure of the opening 311 is obscured by the handle mechanism 32.

[0071] See also Figure 6 and Figure 7 ,in, Figure 6 It is a schematic diagram of the exploded structure of the handle mechanism in one embodiment of the present application. Figure 7 The diagram shows a partial enlarged schematic diagram of the storage space in one embodiment of the present application. Figure 6 As shown, the handle mechanism 32 includes a tensile structure 321. Figure 7 As shown, the storage space 31 includes a stretching channel 312. In one example, the stretching structure 321 can be pulled out of the stretching channel 312 to enable the handle mechanism 32 to switch to Figure 4 In another example, the stretching structure 321 can be extended into the stretching channel 312 to switch the handle mechanism 32 to the state shown in FIG. Figure 3 Hidden state shown.

[0072] In one embodiment, the number and shape of the stretching structure 321 are adapted to the stretching channel 312. For example, when the number of the stretching channel 312 is one, the number of the stretching structure 321 is one, and when the stretching channel 312 is a hollow columnar structure, the stretching structure 321 is a slender column. Furthermore, in order to reduce the friction between the handle mechanism 32 and the stretching channel 312 when switching between the standby state and the hidden state, and to increase the service life of the handle mechanism 32, the surface of the stretching structure 321 is smooth, and its diameter is slightly smaller than the inner diameter of the stretching channel 312. In order to make the handle mechanism 32 durable and load-bearing, the material of the stretching structure 321 includes but is not limited to metal, composite material, high-strength plastic, etc.

[0073] In one embodiment, the stretching structure 321 includes at least one rod, and the rod is adapted to the stretching channel 312. In one example, the stretching structure includes a rod, and the rod is a slender column, which is arranged at the center of the handle mechanism. In this example, the handle mechanism is generally in a "T" shape. Figure 6In the example shown, the stretching structure 321 includes two rods. For the sake of distinction, the two rods are respectively referred to as the first rod and the second rod. The first rod 3211 and the second rod 3212 are symmetrically arranged at both ends of the handle mechanism 32 and are both slender columns. In this example, the handle mechanism 32 is generally in the shape of a letter "П". Of course, in order to increase the stability of the stretching structure in the stretching channel, the stretching structure may include more rods, and this application does not limit this.

[0074] It should be noted here that Figure 6 The first rod 3211 and the second rod 3212 shown are for exemplary purposes only. In an embodiment, the cross-sections of the first rod and the second rod include but are not limited to circular, quasi-circular, polygonal and quasi-polygonal shapes, as long as they can adapt to the shape of the stretching channel that is pulled out or extended.

[0075] See also Figure 8 Combined with Figure 6 , Figure 8 Show this application Figure 6 The enlarged schematic diagram of the tensile structure at A in the embodiment shown is as follows: Figure 6 and Figure 8 As shown, a blocking structure 3213 is disposed at the end of the stretching structure 321, and the blocking structure 3213 is used to prevent the handle mechanism 32 from being pulled out of the storage space 31. That is to say, the blocking structure 3213 is used to restrict the stretching structure 321 in the stretching channel 312, and when the operator holds the handle mechanism 32 in the waiting state to operate the measuring device, such as transferring the measuring device to another position, the blocking structure 3213 provides a connection point between the handle mechanism 32 and the inside of the base, and transfers the tension on the handle mechanism 32 to the measuring device, so that the operator can move the measuring device by holding the handle mechanism.

[0076] Further, the blocking structure 321 can be arranged at the ends of the first rod 3211 and the second rod 3212 of the stretching channel. The following description will be made by taking the blocking structure 3213 arranged at the end of the first rod 3211 as an example. In order to limit the stretching structure 321 in the stretching channel 312, the width of the blocking structure 3213 is greater than the width of the first rod 3211 of the stretching structure 321, and the length thereof can be much smaller than the length of the first rod 3211 of the stretching structure 321. It should be understood that the length refers to the distance that the blocking structure or the stretching structure extends into the interior of the base. When the first rod 3211 and the blocking structure 3213 are cylinders, the width refers to the diameter of the blocking structure or the first rod 3211. Of course, the blocking structure 3213 can be configured in any shape, depending on actual needs and the design choice of the manufacturer.

[0077] exist Figure 6In the example shown, the blocking structure 3213 is configured as a blocking disc and is configured at the end of the first rod 3211. The diameter of the blocking disc is larger than the diameter of the first rod 3211, and its length is much smaller than the length of the first rod 3211. In order to achieve the matching of the stretching structure and the stretching channel, the stretching channel can be divided into two parts. In order to distinguish, the two parts of the stretching channel are respectively referred to as the first stretching channel and the second stretching channel. The first stretching channel is connected to the accommodating space and is used to provide a stretching space for the first rod 3211 of the stretching structure 321. The second stretching channel is connected to the first stretching channel and is used to provide a stretching space for the blocking disc. Since the diameter of the blocking disc is larger than the diameter of the first rod 3211, the inner diameter of the second stretching channel is also larger than the inner diameter of the first stretching channel.

[0078] The blocking structure 3213 and the first rod 3211 are connected in a fixed manner, and the fixed connection manner includes but is not limited to welding, bonding, mortise and tenon connection, and integral molding, etc. Preferably, the blocking structure 3213 and the first rod 3211 can be formed in an integral molding manner.

[0079] In order to facilitate the operation of operators, Figure 6 As shown, the handle mechanism 32 may further include an operating structure 322. Figure 7 As shown, the entrance of the stretching channel 312 is connected to an operation accommodating area 313 adapted to the operation structure 322, and the operation structure 322 is placed in the operation accommodating area 313 when the handle mechanism 32 is in a hidden state. It should be noted that the operation accommodating area may not be provided, and in this case, the operation structure is fitted with the shell of the base. In this example, the operation structure may be configured as a flat structure, so that when the handle mechanism is put into the accommodating space, it can occupy less working space of the measuring device.

[0080] The operating structure 322 provides an operating space for the operator, and the operator can operate the measuring device by holding the operating structure 322, for example, to perform operations such as transfer and adjustment that require contact with the measuring device. Figure 6 In the example shown, the operating structure 322 may be configured as a grip structure, and an operator operates the grip structure to operate the measuring device. For example, the operator's palm passes through the grip structure to operate the handle mechanism.

[0081] Furthermore, the operating structure 322 is connected to the stretching structure 321, and the connection method can be a fixed connection. In one example, the front end of the stretching structure 321 is provided with a thread, and matchingly, the end surface of the operating structure 322 in contact with the stretching structure 321 is provided with a screw hole, and the thread and the screw hole can cooperate with each other to achieve a fixed connection between the operating structure 322 and the stretching structure 321. For example, when the stretching structure 321 rotates clockwise along the screw hole, the stretching structure 321 is tightened on the operating structure 322, and when the stretching structure 321 rotates counterclockwise along the screw hole, the stretching structure 321 is loosened on the operating structure 322.

[0082] In one embodiment, if Figure 6 As shown, the operating structure 322 is provided with a gripping portion 3221 for facilitating the operator to extend or pull out the handle mechanism. That is, the operator can operate the handle mechanism 32 by holding the gripping portion 3221. Further, the gripping portion 3221 can be configured as a recessed structure formed on the surface of the operating structure 322, the recessed structure provides a handling space, and the operator's fingers can be located in the recessed structure. In one example, the recessed structure is configured as a recessed portion formed by a downward depression on the surface of the operating structure, and the operator's fingers can be placed in the recess for easy operation. In another example, the recessed structure may also include a first recess and a second recess, the first recess and the second recess being relatively distributed on the upper surface and the lower surface of the operating structure 322 for holding, for example, the operator's fingers are placed in the first recess and the second recess respectively, so as to grasp the handle mechanism 32 so that it can be extended in or pulled out relative to the base 3. Of course, the gripping portion 3221 may not be provided, and the operator may directly grip the operating structure 322 .

[0083] Matchingly, such as Figure 7 As shown, the operation accommodation area 313 is provided with a gripping area 3131. Figure 6 , the gripping area 3131 corresponds to the gripping portion 3221 to provide a space for the operator to contact the gripping portion 3221. For example, the gripping area 3131 can be configured as a recessed structure formed at the junction of the shell of the base and the operation accommodating area. In order to distinguish it from the recessed structure on the surface of the operation structure, the recessed structure on the surface of the operation structure is referred to as the first recessed structure, and the recessed structure on the operation accommodating area is referred to as the second recessed structure. The first recessed structure and the second recessed structure will not be described in detail later.

[0084] In one example, the number of the first recessed structures and the second recessed structures are equal and their positions are relative. Specifically, when the first recessed structure includes only one recessed portion and is located at the center of the upper surface of the operating structure, the second recessed structure also includes only one recessed portion and is located at the center of the upper surface where the operating accommodating area and the shell of the base are connected; when the first recessed structure includes two recessed portions and are respectively located at the center of the upper and lower surfaces of the operating structure, the second recessed structure also includes two recessed portions and are respectively located at the center of the upper and lower surfaces where the operating accommodating area and the shell are connected.

[0085] Please combine Figure 6 and Fig. 9 ,in, Fig. 9 The schematic diagram of the operation structure in one embodiment of the present application is shown as follows: Figure 6 and Fig. 9 As shown, the operating structure 322 includes an operating housing 3222, and the operating housing 3222 is configured to have an outer contour adapted to the housing of the base, so that the operating housing 3222 closes the opening 311 in a complementary manner to the opening 311. In one example, the operating housing is made of the same material and color as the housing of the base. When the handle mechanism 32 is in a hidden state, in terms of visual effect, when the operating housing 3222 and the housing of the base are aligned with each other, the internal structure of the storage space, such as the stretching channel, the operating accommodating area and other structures are blocked by the operating housing 3222. In this way, when the handle mechanism 32 is in a hidden state, it does not occupy the working space of the measuring device, and can also be visually integrated with the housing of the base.

[0086] like Fig. 9 As shown, the operating structure 322 may further include an operating body 3223, and the operating body 3223 is at least partially wrapped by the operating shell 3222 to serve as a rigid support for the operating structure 322. For example, the gripping portion 3221 configured on the operating structure in the aforementioned embodiment may be formed on the operating shell 3222, and the operator may hold the gripping portion 3221 located on the operating shell 3222 to extend the stretching structure into the stretching channel, so that the handle mechanism 322 is in the form of a Figure 3 The hidden state shown in the figure, or the stretching structure is pulled out from the stretching channel so that the handle mechanism 32 is in a Figure 4 Furthermore, the gripping portion 3221 on the operating housing 3222 matches the edge contour of the housing 34 of the base, so that the handle mechanism can be consistent with the overall appearance of the base when it is hidden, which can make the base more beautiful and increase the hiding effect of the handle mechanism.

[0087] The following is combined with Figures 1 to 6 The following describes a process for an operator to use the handle mechanism configured on the base of the measuring device disclosed in the embodiment of the present application.

[0088] When the measuring device needs to be moved or adjusted, the operator can hold the operating structure 322 on the handle mechanism 32 to extend the handle mechanism 32 from the storage space 31 to present a Figure 4 The operation state shown in the figure is that the rod of the stretching structure 321 is pulled out from the stretching channel 312, and the operator can hold the operating structure 322 to lift the measuring device to adjust or transfer the position. When the handle mechanism 32 is not needed, the operator can push the operating structure 32 to make the rod of the stretching structure 321 of the handle mechanism 32 extend along the stretching channel 312 until the operating structure 322 is located in the operation accommodation area 313 and the operating structure 322 complements the opening 311 so that the opening 311 is closed, thereby presenting the following figure: Figure 3 In the hidden state shown, the handle mechanism is visually integrated with the base and does not occupy the working space of the measuring device.

[0089] In summary, in order to overcome the technical problem that the handle mechanism is fixedly arranged on the outside of the articulated arm type measuring device in the related art, thereby occupying the working space of the measuring device and hindering the measurement of the device, the measuring device provided by the present application is provided with a mutually compatible storage space and a handle mechanism on the base, and the handle mechanism is stored in the storage space, so that it will not occupy the working space of the measuring device. In addition, the handle mechanism can be extended from the storage space to present a waiting state, so that when the measuring device needs to be transferred or adjusted, the handle mechanism can be convenient for the operator to use. Furthermore, by arranging a balancing mechanism on the measuring device, and configuring the balancing mechanism to include an external support structure and a balancing structure, the external support structure is sleeved on the peripheral side of the arm member to support the arm member, and the balancing structure is connected to the external support structure and connected to the base of the measuring device, so that the external support structure bears the force of the balancing structure and further transfers it to the base, avoiding the deflection deformation of the arm member of the measuring device. Secondly, the balancing structure is sleeved on the shaft assembly corresponding to the arm member through its shaft sleeve assembly, and the balancing assembly of the balancing structure is sleeved on the shaft sleeve assembly and connected to the external support structure, so that the balancing structure is easy to be detached and replaced from the measuring device.

Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present application.
