[0049] The tray is used to carry the electric energy meter and carry out the assembly line type detection. The existing tray includes a base body and a limiting structure, the limiting structure is arranged on the base body to limit and fix the electric energy meter carried on the base body, thereby guaranteeing the stability of the fixed electric energy meter. The electric energy meter includes single-phase electric meter, three-phase electric meter and terminal electric meter and various types, but the limiting structure can only adapt to fix a single type of electric meter, when other types of electric meters need to be carried on the base body, the limiting structure will interfere with them, that is, the compatibility of the existing tray is poor. In the related art, multiple limiting structures are arranged on the tray to correspond to different types of electric meters, but the limiting structures of the tray under this setting do not have universality, so that the manufacturing cost of the tray is high and the structure is complex.

[0050] Therefore, referring to Figures 1-8The utility model discloses an embodiment provides a tray assembly 100 for bearing electric energy meter, and electric energy meter includes first electric energy meter 210 and second electric energy meter 220, and first electric energy meter 210 and second electric energy meter 220 can be any suitable type electric energy meter, and except first electric energy meter 210 and second electric energy meter 220, tray assembly 100 can also be suitable for bearing other electric energy meter. Specifically, tray assembly 100 includes base body 110 and limiting assembly 120.

[0051] Referring to Figures 1-3 , base body 110 is used for bearing electric energy meter. Specifically, one side of base body 110 has a bearing surface 119 for bearing electric energy meter, and the bearing surface 119 can be located on the upper side of the base body 110. The base body 110 is provided with a first slot 111 and a second slot 112, and the first slot 111 and the second slot 112 both penetrate the bearing surface 119. In other words, the first slot 111 and the second slot 112 can be recessed in the bearing surface 119.

[0052] Referring to Figures 1-3 , limiting assembly 120 is used for limiting electric energy meter. Specifically, the limiting assembly 120 includes a first limiting part 121. In order to improve the use flexibility of the limiting assembly 120 under different limiting requirements, the first limiting part 121 is detachably connected to the base body 110. The detachable connection between the first limiting part 121 and the base body 110 can be any one of buckle connection, nested connection, magnetic attraction connection and screw connection.

[0053] In order to meet the different limiting requirements required by different types of electric energy meters, referring to Figures 1-2 and Figures 5-6, the tray assembly 100 has a first installation state and a second installation state, in the first installation state, the first limiting part 121 is located in the first slot 111 and protrudes from the bearing surface 119, so as to be suitable for positioning the first electric energy meter 210 carried on the bearing surface 119; in the second installation state, the first limiting part 121 is located in the second slot 112 and protrudes from the bearing surface 119, so as to be suitable for positioning the second electric energy meter 220 carried on the bearing surface 119. That is to say, the position distribution of the first slot 111 and the second slot 112 respectively corresponds to the positioning requirement of the first electric energy meter 210 and the second electric energy meter 220, the first limiting part 121 can be arranged at least partially extending from the first slot 111 or the second slot 112, so that the limiting assembly 120 can limit the first electric energy meter 210 or the second electric energy meter 220, thereby guaranteeing the stability of the tray assembly 100 carrying the electric energy meter. Through the above arrangement, the first limiting part 121 can have multiple limiting functions, and the limiting function of the first limiting part 121 can be changed by changing the position of the first limiting part 121 under different limiting requirements, thereby facilitating the simplification of the limiting structure of the tray assembly 100, reducing the manufacturing cost, and facilitating the switching operation under different limiting requirements. It should be noted that the position switching action of the first limiting part 121 between the first slot 111 and the second slot 112 can be completed manually or automatically by driving equipment.

[0054] In the technical scheme of the utility model, the tray assembly 100 includes a base body 110 and a limiting assembly 120. The base body 110 has a bearing surface 119 on one side for carrying electric energy meters, and the base body 110 is provided with a first slot 111 and a second slot 112, both of which penetrate the bearing surface 119. The limiting assembly 120 includes a first limiting part 121, which is detachably connected to the base body 110. In particular, according to different limiting requirements corresponding to different types of electric energy meters, the tray assembly 100 has a first installation state and a second installation state, in the first installation state, the first limiting part 121 is located in the first slot 111 and protrudes from the bearing surface 119, so as to be suitable for positioning the first electric energy meter 210 carried on the bearing surface 119; in the second installation state, the first limiting part 121 is located in the second slot 112 and protrudes from the bearing surface 119, so as to be suitable for positioning the second electric energy meter 220 carried on the bearing surface 119. In related technologies, multiple limiting structures are provided on the tray to correspond to different types of electric meters. Compared with this, in the scheme of the utility model, the first limiting part 121 has multiple limiting functions, and the limiting function of the first limiting part 121 can be changed by changing the position of the first limiting part 121 under different limiting requirements. Therefore, the tray assembly 100 of the utility model has a simple structure, low manufacturing cost, and convenient switching operation under different limiting requirements.

[0055] The specific cooperation forms of the first limiting part 121 and the first slot 111 and the second slot 112 are introduced as follows. Referring to Figures 3-4 In some embodiments, the first limiting part 121 has a limiting protrusion 1211, the bottom surface of the first slot 111 has a first limiting hole 1111, and the bottom surface of the second slot 112 has a second limiting hole 1121. The limiting protrusion 1211, the first limiting hole 1111, and the second limiting hole 1121 all extend in a direction perpendicular to the bearing surface 119. According to the above arrangement, in order to fixedly install the first limiting part 121, in the first installation state, the limiting protrusion 1211 extends into the first limiting hole 1111; in the second installation state, the limiting protrusion 1211 extends into the second limiting hole 1121. It should be noted that the limiting protrusion 1211, the first limiting hole 1111, and the second limiting hole 1121 can all have any suitable cross-sectional shape, and the cross-sectional shape of the limiting protrusion 1211 can be the same as or different from the cross-sectional shape of the first limiting hole 1111 and the second limiting hole 1121.

[0056] Further, in order to more reliably install the limiting protrusion 1211, referring to Figures 1-4 In some embodiments, the tray assembly 100 further includes a first limiting sleeve 130 located at the first limiting hole 1111 and a second limiting sleeve 140 located at the second limiting hole 1121. The first limiting sleeve 130 and the second limiting sleeve 140 are both hollow. In the first installation state, the limiting protrusion 1211 extends into the first limiting sleeve 130; in the second installation state, the limiting protrusion 1211 extends into the second limiting sleeve 140. It can be understood that the first limiting sleeve 130 is at least partially located in the first limiting hole 1111, and the second limiting sleeve 140 is at least partially located in the second limiting hole 1121. The first limiting sleeve 130 and the second limiting sleeve 140 can be fixedly installed by their own elasticity or installation structure. The limiting protrusion 1211 is fixed by being arranged in the first limiting sleeve 130 or the second limiting sleeve 140 in the first installation state and the second installation state. This arrangement makes the installation of the limiting protrusion 1211 more reliable and stable (because the dimensional accuracy of the first limiting sleeve 130 and the second limiting sleeve 140 is greater than the dimensional accuracy of the first limiting hole 1111 and the second limiting hole 1121), and on the other hand, when the size of the limiting protrusion 1211 needs to be changed (or other limiting part structures also need to be installed), the first limiting sleeve 130 and the second limiting sleeve 140 can be replaced to conveniently adapt.

[0057] In addition, in some embodiments, the cooperation between the first limiting part 121 and the first limiting hole 1111 (or the first limiting sleeve 130) and the second limiting hole 1121 (or the second limiting sleeve 140) is a clearance fit, that is, in the direction parallel to the bearing surface 119, the maximum size of the first limiting hole 1111 or the maximum size of the second limiting hole 1121 is greater than the maximum size of the limiting protrusion 1211; in other embodiments, the cooperation between the first limiting part 121 and the first limiting hole 1111 (or the first limiting sleeve 130) and the second limiting hole 1121 (or the second limiting sleeve 140) is an interference fit, that is, in the direction parallel to the bearing surface 119, the maximum size of the first limiting hole 1111 or the maximum size of the second limiting hole 1121 is smaller than the maximum size of the limiting protrusion 1211, at this time, the limiting protrusion 1211 or the hole wall of the first limiting hole 1111 and the second limiting hole 1121 can be a soft material, such as rubber or silicone.

[0058] Referring to Figure 2 and Figure 6In some embodiments, in the first installation state, the first limiting part 121 is used to divide the bearing surface 119 into a first bearing area 1191, which is suitable for accommodating the first electric energy meter 210; in the second installation state, the first limiting part 121 is used to divide the bearing surface 119 into a second bearing area 1192, which is suitable for accommodating the second electric energy meter 220; the electric energy meters include a third electric energy meter 230, and the tray assembly 100 also has a third installation state, in which the first limiting part 121 is used to divide the bearing surface 119 into a third bearing area 1193. For the specific form of the first limiting part 121 dividing the bearing surface 119 into the third bearing area 1193, the first limiting part 121 can also be installed in the groove of the base body 110 to form the third bearing area 1193, and the specific description is given below. The third bearing area 1193 is suitable for accommodating the third electric energy meter 230. According to the above arrangement of each bearing area, correspondingly, in some embodiments, the first electric energy meter 210 is a single-phase electric meter, the second electric energy meter 220 is a three-phase electric meter (including a three-phase direct electric meter, a three-phase mutual inductance electric meter, etc.), and the third electric energy meter 230 is a terminal electric meter. In addition, in other embodiments, different electric energy meters can correspond to electric energy meters of different sizes, for example, the second electric energy meter 220 and the third electric energy meter 230 can both be three-phase electric meters, and the difference lies in the different sizes between the second electric energy meter 220 and the third electric energy meter 230. For example, in some embodiments, the size of the single-phase electric energy meter is 112mm*160mm, the size of the three-phase electric energy meter is 160mm*250mm, and the size of the terminal electric energy meter is 180mm*260mm. Considering the need to make the placement position of the electric energy meter meet the requirements that the probe can be matched with the terminal post hole position after the tray assembly 100 is positioned, the arrangement of each limiting part needs to be based on the specific size of the electric energy meter and arranged according to the compatible terminal seat connection position.

[0059] In addition, in order to make the tray assembly 100 have better limiting effect on the electric energy meter, referring to Figures 1-8In some embodiments, the limiting component 120 further includes a second limiting part 122, which is detachably connected to the base 110. The base 110 is also provided with a third groove 113 and a fourth groove 114, both of which penetrate the bearing surface 119. The second limiting part 122 can cooperate with the first limiting part 121. Specifically, in some embodiments, in the first installation state, the second limiting part 122 is located in the third groove 113 and protrudes from the bearing surface 119, and the first limiting part 121 and the second limiting part 122 are adapted to jointly position the first energy meter 210 supported on the bearing surface 119. Similarly, in some embodiments, in the second installation state, the second limiting part 122 is located in the fourth groove 114 and protrudes from the bearing surface 119, and the first limiting part 121 and the second limiting part 122 are adapted to jointly position the second energy meter 220 supported on the bearing surface 119. It is understandable that the arrangement and function of the second limiting part 122 are the same as or similar to those of the first limiting part 121. In the first or second installation state, the first limiting part 121 and the second limiting part 122 can jointly serve as the installation positioning structure for the energy meter. For example, the first limiting part 121 and the second limiting part 122 can respectively enclose and separate two parts of the first bearing area 1191, or the first limiting part 121 and the second limiting part 122 can jointly enclose and separate the first bearing area 1191. Furthermore, in Figures 1-8 In the embodiment shown, the first limiting part 121 and the second limiting part 122 have the same shape and size. Correspondingly, the first groove 111, the second groove 112, the third groove 113 and the fourth groove 114 also have the same shape and size. Thus, the first limiting part 121 and the second limiting part 122 can be manufactured at the same time, and there is no need to distinguish between the first limiting part 121 and the second limiting part 122 when disassembling and assembling, making the use of the tray assembly 100 more convenient.

[0060] For more specific positioning requirements of a particular type of electricity meter, additional limit structures can be set up. See [link to relevant documentation] for details. Figures 1-8In some embodiments, the limiting assembly 120 further comprises a third limiting part 123 which is detachably connected to the base 110. The base 110 is further provided with a fifth slot 115 and a sixth slot 116, both of which extend through the bearing surface 119. Along the first direction X which is parallel to the bearing surface 119, the first slot 111 and the third slot 113 are respectively located on the two sides of the fifth slot 115. Along the second direction Y which is parallel to the bearing surface 119 and perpendicular to the first direction X, the second slot 112 and the fourth slot 114 are respectively located on the two sides of the sixth slot 116. In the first installation state, the third limiting part 123 is located in the fifth slot 115 and protrudes out of the bearing surface 119, so that the first limiting part 121 and the third limiting part 123 are adapted to jointly position one first electric energy meter 210 carried on the bearing surface 119, and the second limiting part 122 and the third limiting part 123 are adapted to jointly position another first electric energy meter 210 carried on the bearing surface 119. In the second installation state, the third limiting part 123 is located in the sixth slot 116 and protrudes out of the bearing surface 119, so that the first limiting part 121 and the third limiting part 123 are adapted to jointly position one second electric energy meter 220 carried on the bearing surface 119, and the second limiting part 122 and the third limiting part 123 are adapted to jointly position another second electric energy meter 220 carried on the bearing surface 119. It can be understood that the third limiting part 123 can also be used to position the electric energy meters, and the third limiting part 123 also has the function of separating the first limiting part 121 and the second limiting part 122. More specifically, taking the first installation state as an example, in the embodiment shown in the drawings, the first limiting part 121 and the second limiting part 122 both extend along the first direction X, and are arranged at intervals along the first direction X. The third limiting part 123 extending along the second direction Y is arranged between the first limiting part 121 and the second limiting part 122. Under this arrangement, the first limiting part 121, the second limiting part 122 and the third limiting part 123 jointly form a "cross" shape, so that the tray assembly 100 can form at least four spaces for accommodating the first electric energy meter 210.

[0061] Referring to Figure 4 For the installation mode of the second limiting part 122 and the third limiting part 123, reference can be made to the cooperation of the limiting protrusion 1211 and the first limiting hole 1111 (or the first limiting sleeve 130), the second limiting hole 1121 (or the second limiting sleeve 140) of the foregoing embodiments. That is, the second limiting part 122 and the third limiting part 123 can be provided with limiting protrusions 1211, and the slot bodies cooperating with the limiting protrusions 1211 are provided with corresponding limiting holes. The sizes and shapes of the limiting protrusions 1211 (or the limiting holes) can be the same or different, which will not be described here.

[0062] Based on the third limiting part 123 and the related arrangement of the foregoing embodiments, in order to make the tray assembly 100 adapt to more diverse electric energy meters, reference can be made to​Figure 5 In some embodiments, the base 110 is further provided with a seventh slot 117 and an eighth slot 118, both of which pass through the bearing surface 119, and the seventh slot 117 and the second slot 112 are respectively located on two sides of the fifth slot 115 along the first direction X, and the eighth slot 118 and the fourth slot 114 are respectively located on two sides of the fifth slot 115 along the first direction X, and the seventh slot 117 and the eighth slot 118 are respectively located on two sides of the sixth slot 116 along the second direction Y. Corresponding to the above arrangement, in some embodiments, the electric energy meter includes a third electric energy meter 230, and the tray assembly 100 further has a third installation state, in which the first limiting part 121 is located in the seventh slot 117 and protrudes from the bearing surface 119, the second limiting part 122 is located in the eighth slot 118 and protrudes from the bearing surface 119, and the third limiting part 123 is located in the sixth slot 116 and protrudes from the bearing surface 119, so that the first limiting part 121 and the third limiting part 123 are adapted to jointly position one third electric energy meter 230 carried on the bearing surface 119, and the second limiting part 122 and the third limiting part 123 are adapted to jointly position another third electric energy meter 230 carried on the bearing surface 119. It can be understood that the arrangement and function of the seventh slot 117 and the eighth slot 118 are similar to those of the second slot 112 and the fourth slot 114, the main difference being that the slots are arranged at different positions and are used to position the third electric energy meter 230. More specifically, in the embodiment shown in the drawings, the shapes and sizes of the second slot 112, the fourth slot 114, the seventh slot 117 and the eighth slot 118 are the same, and the second slot 112 and the seventh slot 117 are arranged substantially symmetrically with respect to the center of the fifth slot 115 along the first direction X. In the above-mentioned embodiment, since the second electric energy meter 220 and the third electric energy meter 230 have slightly different sizes along the first direction X, the second slot 112 and the seventh slot 117, and the fourth slot 114 and the eighth slot 118 are not completely symmetrically arranged according to the size difference, and at the same time, a clearance groove is provided on one side of the frame of the base 110, which is recessed along the first direction X, so as to avoid the third electric energy meter 230 with larger size along the first direction X. Figures 1-8 It can be understood that by the position arrangement of the slots and the cooperation of the first limiting part 121 (the second limiting part 122) and the frame of the base 110, the electric energy meter can be fixed along the first direction X. In addition, in order to fix the electric energy meter along the second direction Y, referring to

[0063] It can be understood that by the position arrangement of the slots and the cooperation of the first limiting part 121 (the second limiting part 122) and the frame of the base 110, the electric energy meter can be fixed along the first direction X. In addition, in order to fix the electric energy meter along the second direction Y, referring to Figure 2In some embodiments, the tray assembly 100 comprises a clamping assembly which can clamp the electric energy meter. Specifically, the clamping assembly is connected to the base 110. The clamping assembly comprises a first clamping part and a second clamping part which can be arranged apart along the second direction Y. It can be understood that the first clamping part can have the same structure as the second clamping part or different structure. The embodiments of the present application take the example of the first clamping part and the second clamping part having the same structure for description. The first clamping part and the second clamping part are both used for clamping the electric energy meter. In some embodiments, the first clamping part and the second clamping part can jointly clamp the electric energy meter. In other embodiments, the first clamping part can move towards the limiting assembly 120 to jointly clamp the electric energy meter. In other embodiments, the second clamping part can move towards the limiting assembly 120 to jointly clamp the electric energy meter. The embodiments of the present application take the example of the first clamping part and the second clamping part cooperating with the limiting assembly 120 (the limiting assembly 120 opposite to the first clamping part and the second clamping part along the second direction Y and cooperating with the first clamping part and the second clamping part, in the first installation state, specifically the first limiting part 121 and the second limiting part 122, in the second and third installation states, specifically the third limiting part 123) to clamp the electric energy meter for description. The clamping assembly of the present scheme can realize the side positioning of the electric energy meter, effectively improve the stability of the tray assembly 100 carrying the electric energy meter, and prevent the electric energy meter from falling off the tray assembly 100. The movement setting of the first clamping part and the second clamping part will be introduced below. In some embodiments, the first clamping part and the second clamping part can be elastically connected to the base 110. It can be understood that the clamping assembly can be provided with a first elastic member and a second elastic member. One end of the first elastic member can be connected to the first clamping part and the other end can be connected to the base 110. One end of the second elastic member can be connected to the second clamping part and the other end can be connected to the base 110. When it is needed to clamp the electric energy meter by the clamping assembly, first drive the first clamping part and the second clamping part to move along the second direction Y away from the limiting assembly 120, at this time the first elastic member and the second elastic member are both subjected to tension, then place the electric energy meter on the carrying surface 119, the first elastic member can drive the first clamping part and the limiting assembly 120 to clamp the electric energy meter by relying on its own tension, and the second elastic member can drive the second clamping part and the limiting assembly 120 to clamp the electric energy meter by relying on its own tension.

[0064] It should be noted that, in order to improve the stability of the assembly of the first elastic member and the second elastic member with the base 110, the base 110 can be provided with a clamping groove, and the first clamping part and the second clamping part can be elastically connected in the clamping groove. Adaptively, the clamping assembly can be provided with a plurality of first clamping parts and a plurality of second clamping parts. The present scheme can further improve the stability of the electric energy meter fixation by providing a plurality of first clamping parts and a plurality of second clamping parts.

[0065] In addition, in some embodiments, the base body 110 is also provided with a frame. A clamping reset mechanism can be arranged on the conveying line. When it is required to place the electric energy meter, the clamping reset mechanism can drive the first clamping part and the second clamping part to open, and after the electric energy meter is placed, the first clamping part and the second clamping part can clamp and position the electric energy meter. In other embodiments, the clamping parts on both sides of the frame can be fixed on the base body 110, and the clamping parts in the middle of the base body 110 can be fixed on the limiting assembly 120, that is, the clamping parts can float vertically along with the limiting assembly 120. It can be understood that the frame can cooperate with the conveying line to convey the tray assembly 100, so as to realize the pipeline transportation of the tray assembly 100. The conveying line can be a belt line.

[0066] In order to form more electric energy meter placement spaces, a plurality of limiting part structures of the same kind can also be arranged. Specifically, see Figures 1-8 In some embodiments, the number of the first limiting parts 121, the first grooves 111 and the second grooves 112 is multiple. Each first groove 111 is distributed on one side of the fifth groove 115 along the second direction Y, and each second groove 112 is distributed on one side of the sixth groove 116 along the first direction X. Taking the first mounting state as an example, after N (N≥) first grooves 111 distributed along the second direction Y are mounted with the first limiting parts 121 one by one, the first limiting parts 121 can form N+ spaces capable of independently placing the first electric energy meter 210. Similarly, see Figures 1-8 In some embodiments, the number of the second limiting parts 122, the third grooves 113 and the fourth grooves 114 is multiple. Each third groove 113 is distributed on one side of the fifth groove 115 along the second direction Y, and each fourth groove 114 is distributed on one side of the sixth groove 116 along the first direction X.

[0067] For the above arrangement, more specifically, in Figures 1-8In the shown embodiment, the number of the first limiting portions 121, the first slots 111, the second slots 112, the second limiting portions 122, the third slots 113 and the fourth slots 114 is two. In the first installation state, the two first limiting portions 121 extending along the first direction X and the one third limiting portion 123 extending along the second direction Y jointly form three electric energy meter placing spaces, and the two second limiting portions 122 extending along the first direction X and the one third limiting portion 123 extending along the second direction Y jointly form three electric energy meter placing spaces, so that six first electric energy meters 210 of the same size and specification can be placed in total; in the second installation state, the two first limiting portions 121 extending along the second direction Y and the one third limiting portion 123 extending along the first direction X jointly form one electric energy meter placing space, and the two second limiting portions 122 extending along the second direction Y and the one third limiting portion 123 extending along the first direction X jointly form one electric energy meter placing space (the distance between the two first limiting portions 121 and the distance between the two second limiting portions 122 are small, so that no placing space is formed), so that two second electric energy meters 220 of the same size and specification can be placed in total. In other embodiments, for the second installation state, the two first limiting portions 121 and / or the two second limiting portions 122 can be spaced apart along the first direction X and form electric energy meter placing spaces.

[0068] In addition, in order to save the space of the bearing surface 119, so as to arrange various slots, see Figure 3 In some embodiments, as viewed in the direction perpendicular to the bearing surface 119, the shape enclosed by the first slot 111 at least partially coincides with the shape enclosed by the second slot 112. That is, the first slot 111 and the second slot 112 are arranged in cross and partially communicate. The same arrangement and similar effect can also be made for other slots, for example, see Figure 3 In some embodiments, as viewed in the direction perpendicular to the bearing surface 119, the shape enclosed by the fifth slot 115 at least partially coincides with the shape enclosed by the sixth slot 116.
