[0078] With the development of industrial technology, the electric energy meter detection has realized the automatic assembly line detection, which improves the detection efficiency. The traditional electric energy meter tray mechanism has many kinds, which is usually divided into single-phase electric energy meter tray mechanism and three-phase terminal electric energy meter tray mechanism. The fixing mode of the traditional electric energy meter tray mechanism is relatively single, and it can only adapt to the placement of one or two of the three kinds of electric energy meters, i.e. single-phase electric energy meter, three-phase electric energy meter and terminal electric energy meter. The tray mechanism cannot be compatible with the placement of single-phase electric energy meter, three-phase electric energy meter and terminal electric energy meter according to different use conditions, which reduces the compatibility of the tray mechanism and increases the detection cost of the tray mechanism for electric energy meters.

[0079] In view of this, in order to solve the technical problem of poor compatibility of the tray mechanism 10 at present, with reference to Figures 1 to 12 An embodiment of the utility model provides a tray mechanism 10, which is used for installing and placing different types of electric energy meters, for example, the tray mechanism 10 can be used for installing and placing single-phase electric energy meter 300, three-phase electric energy meter 400, terminal electric energy meter 500 and the like. The tray mechanism 10 comprises a base 100 and a limiting assembly 200.

[0080] The base 100 has a mounting surface 121 for mounting an electric energy meter, for example, the mounting surface 121 can be located on the upper side of the base 100. The mounting surface 121 is provided with at least a first limiting groove 1211 and a second limiting groove 1212. The first limiting groove 1211 and the second limiting groove 1212 can be arranged through the mounting surface 121. The limiting assembly 200 includes at least a first limiting part 210, a second limiting part 220, and a third limiting part 230. The first limiting part 210 and the second limiting part 220 are arranged in parallel, and the third limiting part 230 is arranged transversely to the first limiting part 210 and the second limiting part 220. A plurality of mounting slots 1213 are formed between the first limiting part 210, the second limiting part 220, and the third limiting part 230, and the mounting slots 1213 are used for mounting and placing electric energy meters. It can be understood that the limiting assembly 200 can include a plurality of first limiting parts 210, a plurality of second limiting parts 220, or a plurality of third limiting parts 230. The first limiting part 210 is arranged in the first limiting groove 1211, and the first limiting part 210 can move relative to the first limiting groove 1211 along a first direction X, so that the first limiting part 210 has a first retracted state of retracting the mounting surface 121 and a first protruding state of at least partially protruding out of the mounting surface 121. The second limiting part 220 is arranged in the second limiting groove 1212, and the second limiting part 220 can move relative to the second limiting groove 1212 along the first direction X, so that the second limiting part 220 has a second retracted state of retracting the mounting surface 121 and a second protruding state of at least partially protruding out of the mounting surface 121. The third limiting part 230 can slide along a second direction Y on the mounting surface 121. The third limiting part 230 can be provided with a groove, and the first limiting part 210 and the second limiting part 220 can be accommodated in the groove, so as to realize the transverse arrangement of the third limiting part 230 and the first limiting part 210 and the second limiting part 220. The first direction X is perpendicular to the mounting surface 121, the second direction Y is perpendicular to the first direction X and perpendicular to a direction from the first limiting part 210 to the second limiting part 220. When the first limiting part 210 and the second limiting part 220 are in different states and the third limiting part 230 is in different positions, different sizes of mounting slots 1213 are correspondingly formed, and the different sizes of mounting slots 1213 are used for mounting different sizes of electric energy meters.

[0081] Specifically, in the embodiment, by adjusting the states of the first limiting part 210 and the second limiting part 220 on the mounting surface 121 and adjusting the position of the third limiting part 230 on the mounting surface 121, different sizes of mounting slots 1213 can be correspondingly formed. At this time, corresponding to the size of the adjusted mounting slots 1213, different models of electric energy meters can be mounted and placed. For details, refer to Figure 1In the initial state, the first limiting part 210 can be in the first protruding state, the second limiting part 220 can be in the second protruding state, and the third limiting part 230 can be disposed at the middle position of the first limiting part 210 and the second limiting part 220 along the second direction Y. For example, referring to Figure 6 and Figure 7 When it is necessary to install the single-phase electric energy meter 300 on the tray mechanism 10, the first limiting part 210 can be kept in the first protruding state, and the second limiting part 220 can be pressed so as to be in the second retracting state by retracting along the first direction X to the installation surface 121, while adjusting the position of the third limiting part 230 on the installation surface 121 (for example, sliding the third limiting part 230 to the middle position of the first limiting part 210 along the second direction Y), at this time, a plurality of installation slots 1213 of the first size are formed between the first limiting part 210 and the third limiting part 230, so that the installation slots 1213 of the first size are adapted to the size of the single-phase electric energy meter 300, and the installation of the single-phase electric energy meter 300 on the tray mechanism 10 is completed.

[0082] For another example, referring to Figure 8 and Figure 9 When it is necessary to install the three-phase electric energy meter 400 on the tray mechanism 10, the state of the first limiting part 210 and the second limiting part 220 on the installation surface 121 can be adjusted again, and the position of the third limiting part 230 on the installation surface 121 can be adjusted again. Exemplarily, the first limiting part 210 can be pressed so as to be in the first retracting state by retracting along the first direction X to the installation surface 121, and the second limiting part 220 can be pressed again so as to be in the second protruding state by protruding along the first direction X to the installation surface 121, while adjusting the position of the third limiting part 230 on the installation surface 121 (for example, sliding the third limiting part 230 to the end position of the second limiting part 220 along the second direction Y), at this time, a plurality of installation slots 1213 of the second size are formed between the second limiting part 220 and the third limiting part 230, so that the installation slots 1213 of the second size are adapted to the size of the three-phase electric energy meter 400, and the installation of the three-phase electric energy meter 400 on the tray mechanism 10 is completed.

[0083] For another example, referring to Figure 10 and Figure 11When the terminal electric energy meter 500 needs to be installed on the tray mechanism 10, the state of the first limiting part 210 and the second limiting part 220 on the installation surface 121 can be adjusted, and the position of the third limiting part 230 on the installation surface 121 can be adjusted. For example, the first limiting part 210 can be kept in the first retracted state, the second limiting part 220 can be kept in the second protruding state, and the third limiting part 230 can be adjusted to the position of the installation surface 121 (for example, the third limiting part 230 is slid along the second direction Y to the other end position of the second limiting part 220), at this time, a plurality of third-size installation grooves 1213 are formed between the second limiting part 220 and the third limiting part 230, so that the third-size installation groove 1213 is adapted to the size of the terminal electric energy meter 500, and the installation of the terminal electric energy meter 500 on the tray mechanism 10 is completed.

[0084] It should be noted that the first limiting part 210 and the second limiting part 220 can be pressed by an external mechanical hand, and the third limiting part 230 can be slid.

[0085] The tray mechanism 10 provided by the embodiment can be compatible with the installation of a plurality of different types of electric energy meters (for example, including but not limited to single-phase electric energy meters 300, three-phase electric energy meters 400, terminal electric energy meters 500, and the like) by switching the protruding states of the first limiting part 210 and the second limiting part 220 and switching the position state of the third limiting part 230. According to the detection requirement, different installation states are realized by automatic switching of the limiting part, corresponding to different types of electric energy meters, the compatible hanging meter seat probe position can be matched, the electric energy meter is connected, and the electric energy meter is detected. The compatibility of the tray mechanism 10 provided by the embodiment is good, and the detection cost of the electric energy meter can be reduced.

[0086] In some embodiments, referring to Figure 1 and Figure 2 The base 100 includes a base body 110 and a cover plate 120. The base body 110 has a first accommodating groove 111 and a second accommodating groove 112. The cover plate 120 is connected to the base body 110, and the cover plate 120 is used to seal the first accommodating groove 111 and the second accommodating groove 112. The side of the cover plate 120 away from the first accommodating groove 111 and the second accommodating groove 112 is an installation surface 121. The first limiting groove 1211 and the first accommodating groove 111 are in communication, and the second limiting groove 1212 and the second accommodating groove 112 are in communication. When the first limiting part 210 is in the first retracted state, the first limiting part 210 is accommodated in the first accommodating groove 111, and the side of the first limiting part 210 away from the first accommodating groove 111 is flush with the installation surface 121. When the second limiting part 220 is in the second retracted state, the second limiting part 220 is accommodated in the second accommodating groove 112, and the side of the second limiting part 220 away from the second accommodating groove 112 is flush with the installation surface 121.

[0087] Specifically, in the embodiment, the first limiting part 210 is completely accommodated in the first accommodating groove 111 in the first retracted state, and at this time, the first limiting part 210 fills the first limiting groove 1211, so that the first limiting groove 1211 and the rest of the mounting surface 121 are flush. Similarly, the second limiting part 220 is completely accommodated in the second accommodating groove 112 in the second retracted state, and at this time, the second limiting part 220 fills the second limiting groove 1212, so that the second limiting groove 1212 and the rest of the mounting surface 121 are flush. With the above structure, the surface of the mounting groove 1213 formed between the first limiting part 210, the second limiting part 220 and the third limiting part 230 is flat, so that the electric energy meter can be stably installed in the mounting groove 1213, preventing the electric energy meter from being skewed in the mounting groove 1213, and improving the calibration effect of the electric energy meter.

[0088] The first limiting part 210 moves away from the first accommodating groove 111 in the first protruding state, and at least partially protrudes from the mounting surface 121. Similarly, the second limiting part 220 moves away from the second accommodating groove 112 in the second protruding state, and at least partially protrudes from the mounting surface 121. With the above structure, the first limiting part 210, the second limiting part 220 and the third limiting part 230 divide the mounting surface 121 into several mounting grooves 1213 for installing electric energy meters.

[0089] In some embodiments, referring to Figure 1 and Figure 2 , the base 100 further comprises a frame assembly 130 and a fixed plate 140. One side of the fixed plate 140 is connected with the frame assembly 130, and the opposite side of the fixed plate 140 is connected with the base body 110 away from the cover plate 120. The side of the fixed plate 140 close to the frame assembly 130 is provided with a code carrying body 141.

[0090] Specifically, in the embodiment, the frame assembly 130 cooperates with the Bosch line (an automatic production line) for conveying the tray mechanism 10 on the belt line. The size of the frame assembly 130 can be 410mm*410mm, so that the frame assembly 130 can fit the conveying line with a width of 400mm, so that the tray mechanism 10 can be conveyed on the conveying line with a width of 400mm between the mounting position, the calibration position and the unloading position. The code carrying body 141 includes relevant information of the tray mechanism 10, and the information of the tray mechanism 10 can be identified by using the RIFD (Radio Frequency Identification) technology, so as to ensure the order of the production line.

[0091] It should be noted that the existing industry standard has a unified standard for the size of the electric energy meter. For example, the size of the single-phase electric energy meter 300 is 112mm*160mm, the size of the three-phase electric energy meter 400 is 160mm*250mm, and the size of the terminal electric energy meter 500 is 180mm*260mm. Considering that the placement position of the electric energy meter can meet the compatible meter seat and ensure that the probe is connected to the terminal hole position after the tray mechanism 10 is positioned, the limiting part position of the tray mechanism 10 needs to be arranged based on the compatible meter seat connection position.

[0092] In some embodiments, referring to Figure 4 and Figure 5 , the first limiting part 210 is provided with a first locking piece 211 near one side of the first accommodating groove 111, and the first accommodating groove 111 is provided with a first locking piece 1111, the first locking piece 1111 and the first locking piece 211 are oppositely arranged, and the first locking piece 211 is clamped to the first locking piece 1111 when the first limiting part 210 is in the first retracted state. The second limiting part 220 is provided with a second locking piece 221 near one side of the second accommodating groove 112, and the second accommodating groove 112 is provided with a second locking piece 1121, the second locking piece 1121 and the second locking piece 221 are oppositely arranged, and the second locking piece 221 is clamped to the second locking piece 1121 when the second limiting part 220 is in the second retracted state.

[0093] Specifically, in the present embodiment, when the first limiting part 210 is pressed once, the first limiting part 210 will move towards the direction close to the first accommodating groove 111, and at this time the first locking piece 211 will move towards the direction close to the first locking piece 1111. When the first locking piece 211 and the first locking piece 1111 are in contact, the first locking piece 211 will be clamped to the first locking piece 1111, so that the first limiting part 210 is stably positioned in the first accommodating groove 111, to keep the first limiting part 210 in the first retracted state. When the first limiting part 210 is pressed again, the first locking piece 211 will be separated from the first locking piece 1111, and at this time the first limiting part 210 and the first locking piece 1111 are in a non-connected state, and the first limiting part 210 can move away from the first accommodating groove 111 (for example, the first limiting part 210 can be driven by a spring) to switch the first limiting part 210 to the first protruding state.

[0094] Similarly, when the second limiting portion 220 is pressed once, the second limiting portion 220 moves towards the second accommodating groove 112, and at this time, the second locking member 221 moves towards the second locking piece 1121. When the second locking member 221 and the second locking piece 1121 are in contact, the second locking member 221 is clamped on the second locking piece 1121, so that the second limiting portion 220 is stably positioned in the second accommodating groove 112, to keep the second limiting portion 220 in the second retracted state. When the second limiting portion 220 is pressed twice, the second locking member 221 is separated from the second locking piece 1121, and at this time, the second limiting portion 220 and the second locking piece 1121 are in a disconnected state. The second limiting portion 220 can move away from the second accommodating groove 112 (for example, the second limiting portion 220 can be driven by a spring) to switch the second limiting portion 220 to the second protruding state.

[0095] It should be noted that the first locking piece 1111 and the second locking piece 1121 can be micro bounce stoppers, and the first locking member 211 and the second locking member 221 can be bump heads. That is, when pressed once, the bump head and the micro bounce stopper are buckled and locked. When pressed twice, the buckle is loosened, and the bump head and the micro bounce stopper are separated.

[0096] In some embodiments, referring to Figure 4 and Figure 5 The first locking piece 1111 includes a first locking arm 11111 and a second locking arm 11112, and the first locking piece 1111 is configured to be close to each other when pressed once, so that the first locking arm 11111 and the second locking arm 11112 clamp the first locking member 211, so that the first limiting portion 210 can be positioned in the first accommodating groove 111 and kept in the first retracted state. And the first locking piece 1111 is configured to be away from each other when pressed twice, so that the first locking arm 11111 and the second locking arm 11112 release the first locking member 211, so that the first limiting portion 210 can be separated from the first locking piece 1111 and can move away from the first accommodating groove 111 to switch to the first protruding state.

[0097] The second locking piece 1121 includes a third locking arm 11211 and a fourth locking arm 11212, and the second locking piece 1121 is configured to be close to each other when pressed once, so that the third locking arm 11211 and the fourth locking arm 11212 clamp the second locking member 221, so that the second limiting portion 220 can be positioned in the second accommodating groove 112 and kept in the second retracted state. And the second locking piece 1121 is configured to be away from each other when pressed twice, so that the third locking arm 11211 and the fourth locking arm 11212 release the second locking member 221, so that the second limiting portion 220 can be separated from the second locking piece 1121 and can move away from the second accommodating groove 112 to switch to the second protruding state.

[0098] Specifically, in the embodiment, the first locking arm 11111 and the second locking arm 11112 cooperate to clamp or release the first locking piece 211, so that the first limiting part 210 can be stably kept in the first retracted state, and the flexibility of the position switching of the first limiting part 210 is improved. And by pressing the first locking piece 1111 once or twice, the switching of the first limiting part 210 between the first retracted state and the first protruding state can be realized, the overall operation is convenient and fast, and the state switching efficiency of the first limiting part 210 can be improved.

[0099] Similarly, the third locking arm 11211 and the fourth locking arm 11212 cooperate to clamp or release the second locking piece 221, so that the second limiting part 220 can be stably kept in the second retracted state, and the flexibility of the position switching of the second limiting part 220 is improved. And by pressing the second locking piece 1121 once or twice, the switching of the second limiting part 220 between the second retracted state and the second protruding state can be realized, the overall operation is convenient and fast, and the state switching efficiency of the second limiting part 220 can be improved.

[0100] In some embodiments, referring to Figure 4 and Figure 5 , the base 100 includes a first elastic member 150 and a second elastic member 160, which can be springs. One end of the first elastic member 150 is connected with the first limiting part 210, and the other end of the first elastic member 150 is arranged in the first accommodating groove 111. When the first limiting part 210 is in the first retracted state, the first elastic member 150 is in a compressed state, and when the first limiting part 210 is in the first protruding state, the first elastic member 150 is in a released state. One end of the second elastic member 160 is connected with the second limiting part 220, and the other end of the second elastic member 160 is arranged in the second accommodating groove 112. When the second limiting part 220 is in the second retracted state, the second elastic member 160 is in a compressed state, and when the second limiting part 220 is in the second protruding state, the second elastic member 160 is in a released state.

[0101] Specifically, in the embodiment, when the first limiting part 210 is pressed once, the first limiting part 210 is positioned in the first accommodating groove 111 by the first locking piece 1111, so that the first limiting part 210 is in the first retracted state, and at this time the first elastic member 150 is in a compressed state. When the first limiting part 210 is pressed twice, the first limiting part 210 is separated from the first locking piece 1111, at this time the first elastic member 150 has a tendency to recover the elastic deformation, and drives the first limiting part 210 to move away from the first accommodating groove 111, so that the first limiting part 210 is automatically switched to the first protruding state, thereby improving the state switching flexibility of the first limiting part 210.

[0102] Similarly, when the second limiting portion 220 is pressed once, the second limiting portion 220 is positioned in the second accommodating groove 112 by the second locking member 1121, so that the second limiting portion 220 is in the second retracted state, and the second elastic member 160 is in the compressed state. When the second limiting portion 220 is pressed twice, the second limiting portion 220 is separated from the second locking member 1121, and the second elastic member 160 has a tendency to recover the elastic deformation and drives the second limiting portion 220 to move away from the second accommodating groove 112, so that the second limiting portion 220 automatically switches to the second protruding state, thereby improving the state switching flexibility of the second limiting portion 220.

[0103] In some embodiments, with reference to Figures 1 to 3 , the mounting surface 121 is provided with a first connecting hole 1214, and the third limiting portion 230 is provided with a second connecting hole 231. A connecting member is sequentially arranged in the second connecting hole 231 and the first connecting hole 1214 to connect the third limiting portion 230 to the mounting surface 121. For example, the first connecting hole 1214 and the second connecting hole 231 can be pin holes, and the connecting member can be a pin. Alternatively, the first connecting hole 1214 and the second connecting hole 231 can be threaded holes, and the connecting member can be a bolt.

[0104] Specifically, in the present embodiment, the third limiting portion 230 is detachably connected to the mounting surface 121. By removing the connecting member from the first connecting hole 1214 and the second connecting hole 231, the third limiting portion 230 can be detached from the mounting surface 121, so as to facilitate adjustment of the connection position of the third limiting portion 230 on the mounting surface 121. By arranging the connecting member in the first connecting hole 1214 and the second connecting hole 231, the third limiting portion 230 can be stably positioned on the mounting surface 121, thereby improving the connection stability of the third limiting portion 230 on the mounting surface 121.

[0105] With the above structure, the connection position of the third limiting portion 230 on the mounting surface 121 can be conveniently adjusted, thereby facilitating change of the size of the mounting groove 1213 formed on the mounting surface 121, so as to facilitate adaptation of the mounting groove 1213 to different sizes of electric energy meters.

[0106] In some embodiments, with reference to Figures 1 to 12 , the base 100 comprises a clamping member 170 configured to move towards or away from the mounting groove 1213, and the clamping member 170 is used to clamp the electric energy meter in the mounting groove 1213. More specifically, the clamping member 170 and the limiting portion together clamp the electric energy meter in the mounting groove 1213.

[0107] Specifically, in the embodiment, the electric energy meter can slide into the installation slot 1213 from the side. When the electric energy meter starts to slide into the installation slot 1213, the side wall of the electric energy meter will contact the clamping piece 170. As the electric energy meter gradually slides into the installation slot 1213, the clamping piece 170 will move away from the installation slot 1213 under the extrusion force of the electric energy meter, so that the electric energy meter can continue to slide into the installation slot 1213. When the electric energy meter completely slides into the installation slot 1213, the clamping piece 170 will move towards the installation slot 1213, thereby eliminating the gap between the clamping piece 170 and the electric energy meter, so as to stably position the electric energy meter in the installation slot 1213, ensure the smooth progress of the electric energy meter calibration procedure, and improve the calibration accuracy of the probe to the electric energy meter.

[0108] In some embodiments, referring to Figures 1 to 12 , the mounting surface 121 is provided with a movable slot 1215, and the movable slot 1215 is provided with a third elastic piece 12151, and the clamping piece 170 is connected to the third elastic piece 12151. Wherein, the clamping piece 170 protrudes from the mounting surface 121, when the clamping piece 170 moves towards the installation slot 1213, the third elastic piece 12151 is in a released state, and when the clamping piece 170 moves away from the installation slot 1213, the third elastic piece 12151 is in an elongated state.

[0109] Specifically, in the embodiment, during the movement of the clamping piece 170 away from the installation slot 1213, the third elastic piece 12151 is stretched, and the third elastic piece 12151 can restrain the clamping piece 170 to prevent the clamping piece 170 from being separated from the base 100. After the electric energy meter completely slides into the installation slot 1213, since there is a certain gap between the electric energy meter and the clamping piece 170, the third elastic piece 12151 has a tendency to recover the deformation at this time, and the third elastic piece 12151 can drive the clamping piece 170 to move towards the installation slot 1213, so that the clamping piece 170 automatically clamps the electric energy meter in the installation slot 1213.

[0110] Correspondingly, the utility model also provides another embodiment of a calibration device, which comprises the tray mechanism 10 and the calibration probe in any of the above embodiments. The tray mechanism 10 is used for installing and placing the electric energy meter. The calibration probe can move towards or away from the tray mechanism 10, and is used for calibrating the electric energy meter.

[0111] Specifically, in the embodiment, the calibration device using the above-mentioned tray mechanism 10 can reduce the calibration cost of the electric energy meter and improve the calibration efficiency of the electric energy meter.

[0112] Thanks to the improvement of the above-mentioned tray mechanism 10, the calibration device of the embodiment has the same technical effects as the above-mentioned tray mechanism 10, which will not be described here.

[0113] It should be noted that the tray mechanism 10 and other contents of the utility model disclosed in the prior art can be referred to, and will not be repeated here.

[0114] The above is only the preferred embodiment of the utility model, and does not limit the patent range of the utility model, and any equivalent structural transformation made by using the utility model specification and the attached drawings, or direct / indirect application in other related technical fields is included in the patent protection range of the utility model.
