Description

Measuring devices and measuring equipment

[0001] This application claims priority to Chinese patent application No. 202311154627.8 filed on September 7, 2023, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the technical field of electrical contact clamping force measurement, and in particular to a measuring device and a measuring equipment using the measuring device. Background Art

[0003] In the power system, during the process of power generation, transmission, distribution and energy conversion, the switchgear can start and close, control and protect the electrical equipment. The isolating switch of the switchgear is mainly a contact finger structure, which realizes the opening and closing control through the insertion and separation of the contact fingers and contacts.

[0004] In order to ensure the temperature rise of the switchgear during long-term operation and the electrical and thermal stability during short-circuit current impact, the contacts need to clamp the contact fingers for a long time. However, during the long clamping process, the overall clamping force of the contacts will be insufficient, resulting in large contact resistance and overheating of the contacts. High temperature overheating affects the spring performance of the contact periphery, further reducing the contact clamping force. When large current passes through, arcs may be generated, and even sparks may be triggered to burn the switchgear. Therefore, it is necessary to regularly test the contact clamping force and perform opening and closing tests on the contacts and contact fingers to ensure that a high clamping force is maintained between the contacts and the contact fingers.

[0005] In switchgear and other electrical equipment, contact switch structures are usually provided with multiple pairs of contacts to improve the power transmission capacity of the electrical equipment. However, when existing measurement devices simulate the clamping force of the contact fingers on the contacts to detect the force, they can usually only detect one pair of oppositely arranged contacts, resulting in low measurement efficiency and poor measurement convenience.

[0038] The realization of the objectives, functional features and advantages of this application will be further explained in conjunction with embodiments and with reference to the accompanying drawings. Modes for Carrying Out the Invention

[0039] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0040] It should be noted that all directional indications in the embodiments of the present application (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0041] At the same time, the meaning of "and / or" or "and / or" appearing in the full text includes three options. Taking "A and / or B" as an example, it includes option A, or option B, or an option in which both A and B are satisfied.

[0042] In addition, the descriptions of "first", "second", etc. in this application are for descriptive purposes only and should not be understood as indicating or implying their relative importance or implicitly indicating the number of the technical features indicated. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of such features. In addition, the technical solutions between the various embodiments can be combined with each other, but this must be based on the fact that they can be implemented by ordinary technicians in this field. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0043] In the power system, during the process of power generation, transmission, distribution and energy conversion, the switchgear can start and close, control and protect the electrical equipment. The isolating switch of the switchgear is mainly a contact finger structure, which realizes the opening and closing control through the insertion and separation of the contact fingers and contacts.

[0044] Specifically, the contact is formed with an insertion space, and the contact finger can be extended into the insertion space of the contact and maintain a tight connection with the contact to achieve circuit conduction. The shape of the contact can be in-line or plum blossom-shaped. The in-line contact is provided with multiple contacts, and the multiple contacts are arranged at intervals along a straight line and are provided in two opposite rows to form an insertion space, which is inserted with the contact finger and pushed against the contact by an elastic support member to give the contact an external force facing the insertion space, thereby effectively improving the clamping force or bite force between the contacts, making the connection between the contacts tighter.

[0045] The plum blossom contact is set as an annular structure, that is, multiple contacts are distributed in a ring shape and form an insertion space. The contact fingers extend into the insertion space and abut against multiple contacts. The plum blossom contact is usually clamped on the outside of the multiple contacts by an annular spring. Similarly, the annular spring is used to give the multiple contacts an external force facing the insertion space, so as to effectively increase the clamping force or biting force between the contacts, making the connection between the contacts tighter.

[0046] However, during the long clamping process, the elastic support members in the in-line contacts and the annular springs in the plum blossom contacts will relax and fatigue to a certain extent, resulting in insufficient clamping force of the contacts on the contact fingers. Due to insufficient clamping force, the gap between the contacts and the contact fingers becomes larger, which will cause the contact resistance to be too large and easily cause the contacts to overheat. Overheating will affect the elastic performance of the contact elastic support members and the annular springs, further reducing the contact clamping force.

[0047] A reduction in the clamping force between the contacts and the contact fingers may cause arcing when a large current passes through, which can easily generate sparks and cause fires, reducing the installability and reliability of electrical equipment. Therefore, the clamping force of the contacts must be regularly tested and measured to understand the clamping force of the contacts in their current service life in real time, and to ensure that a high clamping force is maintained between the contacts and the contact fingers to ensure the safe operation of electrical equipment.

[0048] In switchgear and other electrical equipment, contact switch structures are usually provided with multiple pairs of contacts to improve the power transmission capacity of the electrical equipment. However, when existing measurement devices simulate the clamping force of the contact fingers on the contacts to detect the force, they can usually only detect one pair of oppositely arranged contacts, resulting in low measurement efficiency and poor measurement convenience.

[0049] Based on the above background and problems, the present application proposes a measuring device 100, which is used to measure the clamping force of a contact. The measuring device 100 includes a bearing structure 1 and a linkage structure 2. The bearing structure 1 is provided with a plurality of first bearing members 14. The linkage structure 2 includes a transmission body 21, a plurality of second bearing members 22, and a sensor 23. The transmission body 21 is provided on the bearing structure 1, and the plurality of second bearing members 22 are provided on the transmission body 21, and each second bearing member 22 is provided corresponding to a first bearing member 14. The sensor 23 is provided on the transmission body 21. The transmission body 21 can drive the plurality of second bearing members 22 to move relative to the first bearing member 14. The sensor 23 is used to measure the clamping force of the contact.

[0050] The transmission body 21 drives the multiple second carriers 22 to move so that the measuring device 100 has an initial state and a working state. In the initial state, the multiple first carriers 14 and the multiple second carriers 22 can be extended into the contacts to be measured; in the working state, the transmission structure can drive the multiple second carriers 22 to move, and be spaced apart from the multiple first carriers 14, and at the same time press against the contacts to detect the clamping force of the contacts through the sensor 23.

[0051] In this embodiment, the measuring device 100 is used to measure the clamping force or bite force of a contact. The supporting structure 1 is a structural support component of the measuring device 100, used to support and install the linkage structure 2. It is understood that the supporting structure 1 can be a platform with a mounting surface, so that the linkage structure 2 is disposed on the mounting surface, or a frame, a trough, or a housing 12 structure with a mounting cavity 121, in which the linkage structure 2 can be disposed, without limitation. In one embodiment, the supporting structure 1 can be a housing 12 structure, so that the upper shell and the bottom shell enclose the mounting cavity 121. At the same time, the measuring device 100 can be changed in size according to the position and structural shape of the contact. It can be a smaller handheld portable testing instrument for measuring fixed contacts or smaller contacts, or a larger fixed tooling table testing instrument, in which contacts can be placed on the measuring device 100 for measurement, or for measuring larger contacts.

[0052] In this embodiment, the first carrier 14 and the second carrier 22 are plate-like or columnar structures, and the first carrier 14 and the second carrier 22 extend toward one end away from the carrier structure 1. The first carrier 14 is fixed to the carrier structure 1, and the second carrier 22 is movable relative to the first carrier 14, so that the spacing between the first carrier 14 and the second carrier 22 can be changed. Specifically, the measuring device 100 has an initial state and an operating state. By adjusting the second carrier 22, the state of the second carrier 22 and the positional relationship between the first carrier 14 and the second carrier 22 are changed, thereby achieving the transition between the initial state and the operating state of the measuring device 100. It is understandable that in traditional measuring devices 100, the measuring device 100 is rigidly inserted into the contact insertion space, which may cause damage to the contacts and inaccurate measurement results, making it impossible to obtain the actual clamping force of the contacts under the current service life.

[0053] In the present application, the second carrier 22 is movable relative to the first carrier 14. By adjusting the second carrier 22, the distance between the first carrier 14 and the second carrier 22 is made smaller. At this time, the measuring device 100 is in the initial state, and the measuring device 100 is easily inserted into the plug-in space formed by the contacts, avoiding rigid insertion of the measuring device 100 and the contacts, and avoiding possible damage to the contacts; the second carrier 22 is adjusted again so that the position of the first carrier 14 relative to the second carrier 22 is fixed, and there is a fixed gap between the first carrier 14 and the second carrier 22. The fixed gap is the same as the gap formed by the plug-in space formed by the contacts to be measured, so that the first carrier 14 and the second carrier 22 can respectively press against the contacts in the plug-in space, giving the contacts an external force away from the plug-in space, and transmitting the external force to the sensor 23 through the transmission structure to realize the measurement of the clamping force of the contacts, so that the real clamping force of the contacts in the current state can be accurately obtained, thereby improving the measurement accuracy.

[0054] In this embodiment, the measuring device 100 also includes a linkage structure 2, which includes a transmission body 21, a sensor 23 and a second carrier 22. The transmission body 21 can be a connecting rod transmission structure or a gear set transmission structure, which is not limited here. The sensor 23 is connected to the transmission body 21, and the transmission body 21 is connected to the second carrier 22.

[0055] It can be understood that the transmission body 21 is used to adjust the second carrier 22. Through the transmission body 21, the second carrier 22 can be moved relative to the first carrier 14, that is, the transmission body 21 includes two parts: an adjusting component and an executing component that are connected to each other. The second carrier 22 is connected to the executing component. The user operates the adjusting component to drive the executing component to move, thereby realizing the movement of the second carrier 22 relative to the first carrier 14 and enabling the measuring device 100 to switch between the initial state and the working state.

[0056] At the same time, the sensor 23 can be a pressure sensor 23, such as a resistive film pressure sensor 23, a cylindrical tensile pressure sensor 23 or a film pressure sensor 23, etc., which is not limited here. The sensor 23 is arranged on the executive component of the transmission structure. When the measuring device 100 enters the working state, that is, the first carrier 14 is fixed relative to the second carrier 22, and the first carrier 14 and the second carrier 22 are arranged in parallel and at intervals. At this time, the first carrier 14 and the second carrier 22 respectively press against the contact and make the sensor 23 start to be subjected to force, so as to detect the clamping force or bite force of the contact in the working state, thereby effectively improving the accuracy of the measurement result, which is closer to the actual clamping force of the contact under the current service life.

[0057] The measuring device 100 of the present technical solution is used to measure the clamping force or biting force of a switch contact. The measuring device 100 is provided with a bearing structure 1 and a linkage structure 2. The bearing structure 1 is provided with a plurality of first bearing members 14. The linkage structure 2 includes a transmission body 21, a plurality of second bearing members 22 and a sensor 23. The transmission body 21 is provided on the bearing structure 1. The plurality of second bearing members 22 and the sensor 23 are connected to the transmission body 21 so that each second bearing member 22 is arranged corresponding to a first bearing member 14. The measuring device 100 has an initial state and a working state. In the initial state, the plurality of first bearing members 14 and the plurality of second bearing members 22 can extend into the contact together. In the working state, the transmission body 21 can drive the plurality of second bearing members 22 to move relative to the first bearing member 14, so that each first bearing member 14 and a second bearing member 22 are arranged at intervals and simultaneously abut against the contact, so as to measure the clamping force of the contact through the sensor 23, thereby realizing the clamping force measurement of multiple pairs of contacts, effectively improving the measurement efficiency and convenience.

[0058] In one embodiment, the supporting structure 1 is provided with a mounting platform 11, which forms a mounting surface 111, and the mounting surface 111 has a length direction and a width direction that are perpendicular to each other. A plurality of first supporting members 14 are arranged on the mounting surface 111 at intervals along the length direction, and each first supporting member 14 extends along the width direction; a plurality of second supporting members 22 are arranged on the transmission body 21 at intervals along the length direction, and each second supporting member 22 extends along the width direction and is arranged corresponding to a first supporting member 14.

[0059] In this embodiment, as shown in Figure 2, the bearing structure 1 includes a bearing body and a mounting platform 11. The bearing body is the main structural component, which is used to carry and install the linkage structure 2. The mounting platform 11 is connected to the bearing body, and the mounting platform 11 extends in a direction away from the bearing body. The mounting platform 11 is formed with a mounting surface 111, and the mounting surface 111 has a length direction and a width direction. The width direction starts from the bearing body and extends toward one end away from the bearing body. The length direction is perpendicular to the width direction, so that multiple first bearing members 14 can be arranged on the mounting surface 111 at intervals along the length direction. At the same time, the first bearing members 14 can extend along the width direction. Each second bearing member 22 is arranged corresponding to each first bearing member 14, so that multiple second bearing members 22 are also arranged on the transmission body 21 at intervals along the length direction.

[0060] It can be understood that the existing type of contact switch structure is an in-line contact, that is, multiple contacts are arranged at intervals along a straight line, and each pair of contacts includes two contacts, and the two contacts are arranged at intervals to form an insertion space. The measuring device 100 corresponds to the in-line contacts and is provided with multiple first carriers 14 and multiple second carriers 22, so that each first carrier 14 and each second carrier 22 are arranged correspondingly to form a contact finger module, each contact finger module corresponds to a contact setting, and can be extended into the insertion space in the initial state. The multiple contact finger modules are arranged at intervals along the length direction and respectively correspond to multiple contact settings in the in-line contacts. In the working state, each first carrier 14 and each second carrier 22 respectively press against two relatively arranged contacts, so that the measuring device 100 can simultaneously measure the clamping force of the in-line contacts with multiple contacts, effectively improving the convenience and efficiency of measurement in heavy inspection tasks.

[0061] In one embodiment, a plurality of first bearing members are integrally formed and enclosed to form a bearing column 15; a plurality of second bearing members 22 are spaced apart on the transmission body 21 around the axis of the bearing column 15, and each second bearing member 22 is spaced apart from the outer wall of the bearing column 15 along the radial direction of the bearing column 15, and the extension direction of the second bearing members 22 is the same as the axial direction of the bearing column 15.

[0062] In this embodiment, as shown in Figure 3, the outer wall of the supporting column 15 is provided with a plurality of first supporting members 14, and the plurality of first supporting members 14 are spaced apart along the circumferential direction of the supporting column 15, and the plurality of second supporting members 22 are spaced apart on the transmission body 21 in an annular or barrel-shaped manner, and are arranged around the axis of the supporting column 15, so that the plurality of second supporting members 22 and the plurality of first supporting members 14 are arranged around the same axis. At the same time, the axial distance from each second supporting member 22 to the supporting column 15 is the same and is greater than the axial distance from the first supporting member 14 to the supporting column 15, so that the plurality of second supporting members 22 are located on the side of the plurality of first supporting members 14 away from the supporting column 15.

[0063] It can be understood that another type of existing contact switch structure is a plum blossom contact, that is, multiple contacts are arranged in a ring shape around a fixed axis, and multiple contacts are jointly enclosed in the center to form an insertion space. In the measuring device 100, multiple second carriers 22 extend into the insertion space in the initial state, and in the working state, multiple second carriers 22 are expanded in the direction away from the supporting column 15 and respectively pressed against the corresponding contacts to achieve rapid measurement of the clamping force of the plum blossom contact, effectively improving the convenience and efficiency of the measurement.

[0064] In one embodiment, the transmission body 21 includes a linkage module 211 and a locking module 212. The linkage module 211 is movably arranged on the supporting structure 1. A plurality of second supporting members 22 and a sensor 23 are arranged on the linkage module 211. The locking module 212 is movably abutted against the linkage module 211. The locking module 212 is arranged on the supporting structure 1 and movably abuts against one end of the linkage module 211 away from the second supporting member 22. The locking module 212 is used to drive the linkage module 211 to rotate so as to convert the initial state and the working state.

[0065] In this embodiment, the transmission body 21 includes a linkage module 211 and a locking module 212. The linkage module 211 is movably arranged on the bearing structure 1, and the first bearing member 14 is connected to the linkage module 211. The locking module 212 is arranged on the bearing structure 1 and movably abuts against the linkage module 211. It can be understood that the linkage module 211 is the above-mentioned execution component, and the locking module 212 is the above-mentioned adjustment component. The locking module 212 is arranged on the bearing structure 1. The measurement personnel can operate the locking module 212 to achieve the abutment or separation of the locking module 212 and the linkage module 211, thereby realizing the transition of the linkage module 211 between the working state and the initial state. The linkage module 211 is used to realize the transmission of motion, such as a connecting rod mechanism or a gear set mechanism, to transmit the motion from the locking module 212 to the first bearing member 14. In addition, while transmitting the motion, the linkage module 211 can also apply pressure to the sensor 23 to measure the clamping force of the contact.

[0066] On the one hand, the locking module 212 is operated by the measurement personnel to realize the control of the first carrier 14. On the other hand, the locking module 212 is used to lock the linkage module 211 in the working state, that is, when the first carrier 14 and the second carrier 22 remain parallel and spaced apart, so that the position of the first carrier 14 is fixed, so that the first carrier 14 on the linkage module 211 continues to press against the contact, and the linkage module 211 continues to apply pressure to the sensor 23 to obtain the clamping force of the contact.

[0067] The locking module 212 can be elastically locked or snap-on locked, which is not limited here.

[0068] In one embodiment, the linkage module 211 is provided with a transmission rod 2111, the transmission rod 2111 is rotatably provided on the supporting structure 1, a plurality of second supporting members 22 and a sensor 23 are provided on the transmission rod 2111, and the locking module 212 is movably abutted against one end of the transmission rod 2111 away from the second supporting member 22; wherein, the locking module 212 can drive the transmission rod 2111 to rotate to drive the plurality of second supporting members 22 to move.

[0069] In this embodiment, the transmission rod 2111 is rotatably mounted on the supporting structure 1, and one end of the transmission rod 2111 extends toward the mounting platform 11, or along the axis of the supporting column 15, and is connected to the second supporting member 22 at its end. The locking module 212 movably abuts against the end of the transmission rod 2111 away from the second supporting member 22, and the sensor 23 is disposed on the force-bearing portion of the transmission rod 2111. In one embodiment, the sensor 23 is disposed at the end of the transmission rod 2111 that abuts the locking module 212, so that when the locking module 212 abuts the transmission rod 2111, the sensor 23 can more accurately detect the force applied to the transmission rod 2111, thereby more accurately detecting the force applied by the contacts to the second supporting member 22, and accurately measuring the clamping force of the contacts.

[0070] At the same time, a rotating connection that is rotatably connected to the supporting structure 1 is formed on the transmission rod 2111, and the rotating connection is located between the abutment of the second supporting member 22 and the locking module 212, so that when the locking module 212 is pressed against the transmission rod 2111, the transmission rod 2111 rotates around the rotating connection, and the second supporting member 22 connected to the other end of the transmission rod 2111 can move in a direction opposite to the pressing direction of the locking module 212, and the second supporting member 22 and the first supporting member 14 are arranged at intervals to press against the contacts, so as to efficiently and accurately transmit the operation of the locking module 212 to the second supporting member 22 through the transmission rod 2111, flexibly switch the initial state and the working state, and efficiently measure the clamping force of the contacts.

[0071] In this embodiment, the transmission rod 2111 is connected to multiple second carriers 22. Specifically, a connecting plate is provided at one end of the transmission rod 2111 connected to the second carrier 22, so that the multiple second carriers 22 are arranged on the connecting plate at intervals along the length direction. Alternatively, a plurality of support rods are provided at one end of the transmission rod 2111 connected to the second carrier 22. The multiple support rods can be arranged in parallel and at intervals, or can be arranged in a fan-shaped diffusion pattern. Each support rod is connected to a second carrier 22, so that the multiple second carriers 22 are arranged at intervals along the length direction.

[0072] It can be understood that at this time, the locking module 212 is movably abutted against the end of the transmission rod 2111 away from the second carrier 22, so that the locking module 212 can push the transmission rod 2111 and make the transmission rod 2111 rotate around the rotating connection. The transmission rod 2111 rotates around the rotating connection at the end away from the locking module 212 at the rotating connection, and drives the multiple second carriers 22 to rotate together through the connecting plate or multiple support rods, so that the multiple second carriers 22 are spaced apart from the multiple first carriers 14 and respectively abut against the contacts. With this arrangement, by operating one locking module 212, the control of the multiple second carriers 22 can be achieved, and the clamping force measurement of multiple contacts can be achieved at the same time, effectively improving the measurement efficiency and the convenience of operation. In addition, one or more sensors 23 can be set. When one sensor 23 is set, the clamping force of multiple contacts can be measured in sequence and the clamping force data can be transmitted. When multiple sensors 23 are set, each sensor 23 can be corresponded to a second carrier 22 to independently detect the clamping force of each contact.

[0073] In one embodiment, the linkage module 211 includes a plurality of transmission rods 2111, which are rotatably provided on the supporting structure 1, each second supporting member 22 is provided on a transmission rod 2111, and the locking module 212 is movably abutted against one end of the transmission rod 2111 away from the second supporting member 22; the linkage structure 2 includes a plurality of sensors 23, so that each sensor 23 is provided on a transmission rod 2111; wherein, the locking module 212 can drive the plurality of transmission rods 2111 to rotate, thereby driving the plurality of second supporting members 22 to move.

[0074] It can be understood that the multiple transmission rods 2111 are spaced apart along the length direction and are all rotatably provided on the supporting structure 1, and the rotation connection points of the multiple transmission rods 2111 are all located on the same straight line along the length direction, so that the second supporting members 22 connected to each transmission rod 2111 are also spaced apart along the length direction; at this time, the locking module 212 is movably abutted against the multiple transmission rods 2111 and can drive the multiple transmission rods 2111 to rotate, thereby driving the multiple second supporting members 22 to move relative to the multiple first supporting members 14. Specifically, the locking module 212 is abutted against one end of the multiple transmission rods 2111 and is provided with a plurality of abutment joints, and the plurality of abutment joints are arranged along the length direction. The second carrier 22 is spaced apart in the degree direction and correspondingly pressed against a transmission rod 2111, so that all or part of the transmission rod 2111 can be manipulated at the same time by the locking module 212, so that all or part of the second carrier 22 moves relative to the first carrier 14 and is spaced apart from the first carrier 14 to measure the clamping force of the contacts, so that the measuring device 100 can measure the clamping force of multiple contacts at the same time through the locking module 212, and can also measure the clamping force of some contacts independently through the locking module 212, so that the use of the measuring device 100 is more flexible, and can adapt to actual inspection needs, thereby improving the versatility and applicability of the measuring device 100.

[0075] In one embodiment, the linkage module 211 includes a plurality of transmission rods 2111, which are rotatably provided on the supporting structure 1, and each second supporting member 22 is provided on a transmission rod 2111. The transmission body 21 includes a plurality of locking modules 212, and each locking module 212 is movably abutted against an end of the transmission rod 2111 away from the second supporting member 22; the linkage structure 2 includes a plurality of sensors 23, so that each sensor 23 is provided on a transmission rod 2111; wherein, each locking module 212 can drive a transmission rod 2111 to rotate to drive a second supporting member 22 to move.

[0076] It can be understood that the linkage module 211 includes multiple transmission rods 2111, and the transmission body 21 includes multiple locking modules 212, so that each locking module 212 can be movably abutted against a transmission rod 2111. Such an arrangement can further improve the flexibility of use of the measuring device 100. A transmission rod 2111 is combined with a locking module 212 and a sensor 23 to independently measure the clamping force of a contact. Therefore, in the actual detection and measurement of the contact, the transmission rod 2111 is operated through the corresponding locking module 212 to be able to more accurately measure the clamping force of a single contact.

[0077] In one embodiment, the locking module 212 includes an elastic locking member 2121 and a limiting column 2122. The elastic locking member 2121 is arranged on the supporting structure 1 and is connected to the limiting column 2122. The limiting column 2122 is movably arranged on the supporting structure 1. The elastic locking member 2121 is used to adjust the limiting column 2122 to abut against or away from the linkage module 211 to realize the transition between the working state and the initial state of the measuring device 100.

[0078] In this embodiment, the elastic locking member 2121 is provided on the supporting structure 1 and is connected to the limiting column 2122. The limiting column 2122 is movably provided on the supporting structure 1, and the axis direction of the limiting column 2122 is perpendicular to the mounting surface 111. It is understood that the elastic locking member 2121 is used to adjust the movement of the limiting column 2122 along its axis direction so that the limiting column 2122 can abut against or move away from the transmission rod 2111. When the elastic locking member 2121 adjusts the limiting column 2122 to abut against the transmission rod 2111, the transmission rod 2111 rotates and keeps the first supporting member 14 and the second supporting member 22 parallel and spaced apart, so that the measuring device 100 enters the working state. At this time, the sensor 23 on the transmission rod 2111 is subjected to force and begins to detect the clamping force. When the elastic locking member 2121 adjusts the limiting column 2122 to move away from the transmission rod 2111, the transmission rod 2111 is not subjected to external force, and the measuring device 100 is in the initial state. The limiting post 2122 can effectively connect the elastic locking member 2121 with the linkage module 211 , thereby transmitting motion to the linkage module 211 and changing the state of the second supporting member 22 .

[0079] In another embodiment of the present application, the supporting structure 1 is further provided with an adjusting block 13, which is slidably provided on the supporting body, and the axial direction of the limiting column 2122 is the same as the sliding direction of the adjusting block 13. The adjusting block 13 is provided with a through hole, and the limiting column 2122 is passed through the through hole, and one end of the limiting column 2122 is connected to the elastic locking member 2121 and is limitedly abutted on the adjusting block 13, and the other end portion of the limiting column 2122 passes through the through hole and abuts against the transmission rod 2111; by sliding the adjusting block 13 along the axial direction of the limiting column 2122, the position of the limiting column 2122 abutting against the transmission rod 2111 can be adjusted, thereby adjusting the position of the transmission rod 2111 and the transmission rod 2111, and then adjusting the distance between the first supporting member 14 and the second supporting member 22, so that the measuring device 100 can adapt to contacts of different specifications, thereby improving the versatility and applicability of the measuring device 100.

[0080] In one embodiment, the elastic locking member 2121 includes an elastic sheet and a locking member, one end of the elastic sheet is connected to the supporting structure 1, and the other end of the elastic sheet is connected to the limiting column 2122. The locking member is movably provided on the supporting structure 1 and movably abuts against the elastic sheet.

[0081] In this embodiment, one end of the elastic sheet is connected to the supporting structure 1, and the other end is connected to the end of the limiting column 2122 away from the transmission rod 2111. The locking member is movably provided on the supporting structure 1, and the locking member can movably abut against the elastic sheet.

[0082] It is understood that the locking member is rotatably disposed on the supporting structure 1, so that the locking member can achieve a change in the state of the elastic sheet by movably abutting against the elastic sheet. When the locking member is tightly abutted against the elastic sheet, the elastic sheet also tightly abuts against the transmission rod 2111 via the limiting post 2122, causing the measuring device 100 to enter the working state. When the locking member is disengaged from the elastic sheet, the elastic sheet is in a relaxed state, and the limiting post 2122 no longer abuts against the transmission rod 2111. At this time, the first supporting member 14 is in a relaxed state, and the measuring device 100 enters the initial state. In other words, the locking member is used to adjust the state of the linkage module 211 and the second supporting member 22 through the elastic sheet, thereby changing the state of the measurement state. At the same time, the locking member also has a locking function in place, so that in the working state, the locking module 212 and the linkage module 211 remain relatively fixed, and the first supporting member 14 and the second supporting member 22 remain relatively fixed, thereby improving the safety and continuity of the detection.

[0083] In addition, the locking member applies pressure to the elastic sheet, and the elastic sheet pushes the limit column 2122 to press against the adjustment block 13, thereby applying the elastic force generated by the deformation of the elastic sheet to the limit column 2122, and applying it to the linkage module 211 through the limit column 2122, so that the second carrier 22 and the first carrier 14 remain relatively fixed. At this time, the elastic force generated by the elastic sheet is sufficient to resist the pressure of the contacts on the first carrier 14 and the second carrier 22, effectively ensuring the normal operation of the first carrier 14 and the second carrier 22, so that the first carrier 14 and the second carrier 22 are stably pressed against the contacts and the clamping force is measured by the sensor 23.

[0084] In one embodiment, the supporting structure 1 is provided with a shell 12, which encloses an installation cavity 121, and the transmission body 21 and the sensor 23 are arranged in the installation cavity 121; the shell 12 is provided with a measuring port 122 connected to the installation cavity 121, the first supporting member 14 is connected to the shell 12, and the second supporting member 22 is connected to the transmission body 21, and the first supporting member 14 and the second supporting member 22 are located at the measuring port 122 and extend in a direction away from the installation cavity 121.

[0085] In this embodiment, the bearing structure 1 is a shell 12 structure, which is provided with a shell 12, and the shell 12 encloses an installation cavity 121. Specifically, the shell 12 includes a bottom shell and an upper shell, and the bottom shell and the upper shell are detachably connected, such as bolted, snap-fitted or plug-in, so that the upper shell and the bottom shell enclose an installation cavity 121, so that the linkage module 211 and the locking module 212 are arranged in the installation cavity 121. Specifically, the transmission rod 2111 and the locking member are rotatably provided on the bottom shell and are located in the installation cavity 121. One end of the transmission rod 2111 extends toward the measuring port 122 and is connected to the second bearing member 22. At the same time, the first bearing member 14 is connected to the shell 12 adjacent to the measuring port 122, so that the first bearing member 14 and the second bearing member 22 extend together in a direction away from the installation cavity 121.

[0086] It can be understood that the shell 12 can better protect the linkage structure 2 provided in the installation cavity 121, such as the internal linkage module 211, the partial locking module 212 and the sensor 23. At the same time, the shell 12 provides installation support for some structures, such as the first carrier 14; the shell 12 includes a detachable bottom shell and an upper shell, so that when the internal linkage structure 2 fails, it can be quickly repaired and replaced, and the measuring port 122 is provided, which also provides sufficient avoidance space for the movement of the second carrier 22, so that it can be inserted into the contact and enter the working state.
