Description

Technical Field

[0001] The invention relates to an electric meter accessory device, in particular to an external module box with multiple installation modes. Background Art

[0002] With the gradual improvement of infrastructure construction and the continuous development of science and technology, the functional upgrade in the power grid renovation project has involved the addition of additional functions such as wireless transmission and handheld devices. Therefore, it is necessary to specially set up corresponding external module boxes on the meter accessories to meet its installation requirements.

[0003] The existing module box has a simple structure and a single fixed installation method, which makes it difficult to debug and disassemble. It cannot be flexibly disassembled and assembled according to multiple actual conditions on site, such as the installation height, disassembly angle, and the ease of coordination with the electric meter, and cannot meet actual installation requirements. Summary of the invention

[0004] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention provides an external module box with multiple installation modes, which can be flexibly disassembled and assembled to fully meet the debugging and installation requirements on site.

[0005] An external module box with multiple installation modes according to an embodiment of the present invention includes:

[0006] The module box body is provided with a mounting position and two groups of first buckling parts, and the two groups of first buckling parts are arranged on two inner side walls opposite to the mounting position;

[0007] A fixed bracket has multiple groups of snap-fitting parts arranged on the circumferential side. The fixed bracket is installed in the installation position by snapping one group of the snap-fitting parts with the first snap-fitting piece. After the fixed bracket is rotated to a set angle, it can be installed in the installation position by snapping another group of the snap-fitting parts with the first snap-fitting piece (that is, after the fixed bracket is rotated to a set angle relative to the module box body, a group of snap-fitting parts in a corresponding position state still satisfy the snap-fitting relationship of the first snap-fitting piece, so that the fixed bracket can be snap-fitted and installed in the installation position).

[0008] The external module box with multiple installation modes according to the embodiment of the present invention has at least the following technical effects:

[0009] The external module box with multiple installation methods proposed in the present invention is first connected to the corresponding fixed structure (such as a slide rail or a wall, etc.) through a fixed bracket, and then the module box body is installed in multiple ways by utilizing the connection method between the fixed bracket and the fixed bracket. Specifically, since the fixed bracket can be rotated to a set angle through multiple sets of buckling parts and correspondingly buckle the first buckling part to achieve installation with the installation position, the fixed bracket can be relatively fixed here, so that the module box body can be installed in multiple ways through the multi-angle buckling between the installation position thereon and the fixed bracket, thereby providing a multi-angle wiring method to meet on-site debugging and installation requirements.

[0010] According to some embodiments of the present invention, the fixed bracket includes a first bracket and a second bracket, and the first bracket is provided with a sliding connection structure at one end away from the installation position for sliding connection to the slide rail, and the second bracket is provided with a flat end surface at one end away from the installation position for fixed connection to the wall. Obviously, compared with the above-mentioned multi-angle snap-fit, two specific structures of the fixed bracket are provided here to facilitate technicians to select and install according to actual installation conditions. For example, in a wide space that is convenient for installing the slide rail, the sliding connection between the first bracket and the slide rail can be used to realize convenient sliding installation of the entire module box, and in a narrow space, the installation structure of the slide rail can be used for fixing, or the second bracket can be used to directly fix it with bolts or screws.

[0011] According to some embodiments of the present invention, the sliding connection structure is provided with a first clamping portion and a second clamping portion for clamping the slide rail, so that the sliding installation of the entire module box can be achieved by sliding the first clamping portion and the second clamping portion relative to the slide rail.

[0012] According to some embodiments of the present invention, a third fastening member that fastens the slide rail is provided on the first clamping portion, and two fourth fastening members that fasten the slide rail are provided on the second clamping portion. The sliding installation of the entire module box can be achieved by fastening the slide rail with the third fastening member and the fourth fastening member.

[0013] According to some embodiments of the present invention, the fixing bracket is provided with reinforcing support structures for supporting the slide rail on both sides of the first clamping portion, so as to improve the bearing strength and sliding stability of the fixing bracket.

[0014] According to some embodiments of the present invention, a connecting hole is provided on the fixed bracket for inserting screws or bolts. Specifically, the first bracket can be fixed to the slide rail by inserting bolts or screws connected to the slide rail through the connecting hole, and the second bracket can be directly fixed to the wall by inserting bolts or screws connected to the wall through the connecting hole.

[0015] According to some embodiments of the present invention, each group of the snap-fitting portions is provided with at least two second snap-fitting parts on both sides of the fixed bracket, and the second snap-fitting parts are used to snap-fit ​​with the corresponding first snap-fitting parts. Obviously, according to this structure, as long as there are second snap-fitting parts on both sides of the fixed bracket that snap-fit ​​with the two groups of first snap-fitting parts, the installation between the fixed bracket and the mounting position can be achieved. Therefore, at least one side of the fixed bracket needs to have a second snap-fitting part that snaps with the first snap-fitting part, and at least two second snap-fitting parts are needed on both sides.

[0016] According to some embodiments of the present invention, when each group of the second fastening parts is fastened with the first fastening parts, the projection width in the vertical direction is adapted to the projection width of the two groups of the first fastening parts in the vertical direction, that is, it is necessary to enable each group of the second fastening parts to be stably fastened and installed in the installation position when fastening with the first fastening parts, thereby ensuring that the module box body and the fixed bracket cannot slip out forward and backward and achieve stable fastening.

[0017] According to some embodiments of the present invention, when each group of second fasteners is fastened with the first fasteners, that is, the second fasteners on both sides for fastening can fit the two inner side walls opposite to the installation position and the bottom plate of the installation position. At the same time, the uppermost end of the fixed bracket can also fit the inner side wall of the upper end (or upper side) of the installation position, thereby fully ensuring the stability of the module box body when it is installed on the fixed bracket.

[0018] According to some embodiments of the present invention, in the above structure, a friction damping structure is provided on the surface of the first fastening member, the inner wall of the mounting position and the bottom plate, so that the friction resistance when the second fastening member slides and fastens the first fastening member can be increased, thereby improving the connection stability between the module box body and the mounting position.

[0019] According to some embodiments of the present invention, the friction damping structure may be configured as a friction pattern or a nylon surface to fully increase the friction resistance.

[0020] According to some embodiments of the present invention, the fixed bracket is provided with a horizontal rectangular fixing plate, and the two sides of each top corner of the rectangular fixing plate are provided with the second buckling parts. Obviously, according to the figure, the rectangular fixing plate provided here is a square fixing plate, and two groups of buckling parts are correspondingly provided. Each group of buckling parts is provided with four identical second buckling parts on both sides of the fixed bracket, one group of buckling parts can realize the vertical suspension of the module box body, so as to facilitate the technician to carry out the lower side wiring, and after rotating 90° (or 270°), the horizontal installation of the module box body can be achieved through another group of buckling parts, which is convenient for the technician to carry out the right side wiring (or left side wiring). Furthermore, when the fixed plate here is not an equilateral square structure, in order to ensure that the fixed bracket can be smoothly installed after rotation, it is necessary to make the second buckling part after rotation able to adapt to the buckling of the first buckling part.

[0021] According to some embodiments of the present invention, four first buckling members are provided, and the four first buckling members are evenly distributed on two inner side walls opposite to the installation position, so as to fully improve the installation stability when the module box body is buckled with the fixing bracket.

[0022] According to some embodiments of the present invention, the first fastening member, the second fastening member, the third fastening member and the fourth fastening member are all configured as horizontal stoppers.

[0023] According to some embodiments of the present invention, the module box body is provided with an installation cavity with an opening at one end, so that a wiring port can be formed for facilitating wiring. In combination with the above-mentioned installation structure, its multi-angle snap-fit ​​multi-mode installation mainly refers to the diversity of wiring directions. For example, after the module box body is vertically hung on a fixed bracket, it is convenient for technicians to connect wires from the lower end, or in specific occasions, it is necessary to install the module box body horizontally to the left or right relative to the fixed bracket, so that technicians can connect wires from the left or right side. There are even some specific situations, such as when the module box is set under the aisle, it is necessary to facilitate technicians to connect wires from the upper side.

[0024] According to some embodiments of the present invention, the structure of the entire installation position can be further set as a rotating structure, so that the module box body can be further rotated relative to the fixed bracket, so as to obtain an installation structure that is more suitable for actual installation conditions. Specifically, a rotating seat can be rotatably set on the rear side of the module box body, and the installation position and its related structures are all arranged on the rotating seat.

[0042] Reference Figures 1 to 8 The present invention proposes an external module box with multiple installation modes, comprising:

[0043] The module box body 100 is provided with a mounting position 101 and two sets of first fastening members 102, and the two sets of first fastening members 102 are arranged on two inner side walls opposite to the mounting position 101;

[0044] The fixed bracket 200 is provided with multiple groups of snap-fitting parts on the circumferential side. The fixed bracket 200 is installed in the installation position 101 by snapping the first snap-fitting piece 102 with one group of snap-fitting parts. After the fixed bracket 200 is rotated to a set angle, it can be installed in the installation position 101 by snapping the first snap-fitting piece 102 with another group of snap-fitting parts (that is, after the fixed bracket 200 is rotated to a set angle relative to the module box body 100, a group of snap-fitting parts in a corresponding position state still satisfy the snap-fitting relationship of the first snap-fitting piece 102, so that the fixed bracket 200 can be snap-fitted and installed in the installation position 101).

[0045] According to the above structure, the external module box with multiple installation methods proposed by the present invention is first connected to the corresponding fixed structure (such as a slide rail 300 or a wall, etc.) through the fixed bracket 200, and then the module box body 100 and the fixed bracket 200 are connected in multiple ways for installation. Specifically, since the fixed bracket 200 can be rotated to a set angle through the multiple sets of buckling parts and correspondingly buckle the first buckling piece 102 to achieve installation with the installation position 101, the fixed bracket 200 can be relatively fixed here, so that the module box body 100 can be installed in multiple ways through the multi-angle buckling between the installation position 101 thereon and the fixed bracket 200, thereby providing a multi-angle wiring method to meet on-site debugging and installation requirements.

[0046] In some embodiments of the present invention, the fixed bracket 200 includes a first bracket and a second bracket, and the end of the first bracket away from the installation position 101 is provided with a sliding connection structure for sliding connection to the slide rail 300, and the end of the second bracket away from the installation position 101 is set as a flat end surface for fixed connection to the wall. Obviously, compared with the above-mentioned multi-angle buckle, two specific structures of the fixed bracket 200 are provided here to facilitate technicians to select and install according to actual installation conditions. For example, in a wide space where it is convenient to install the slide rail 300, the sliding connection between the first bracket and the slide rail 300 can be used to realize convenient sliding installation of the entire module box, and in a narrow space, the installation structure of the slide rail 300 can be used for fixing, or the second bracket can be used to directly fix it with bolts or screws.

[0047] In some embodiments of the present invention, Figure 1 to Figure 5 As shown, the sliding connection structure is provided with a first clamping portion 201 and a second clamping portion 203 for clamping the slide rail 300 , so that the sliding installation of the entire module box can be achieved by sliding the first clamping portion 201 and the second clamping portion 203 relative to the slide rail 300 .

[0048] In some embodiments of the present invention, Figure 4 , Figure 5 As shown, a third fastening member for fastening the slide rail 300 is provided on the first fastening portion 201, and two fourth fastening members for fastening the slide rails 300 are provided on the second fastening portion 203. By cooperating with the third fastening member and the fourth fastening member to fasten the slide rails 300, the sliding installation of the entire module box can be achieved.

[0049] In some embodiments of the present invention, Figure 4 , Figure 5 As shown, the fixing bracket 200 is provided with a reinforcing support structure 202 for supporting the slide rail 300 on both sides of the first clamping portion 201 , so as to improve the bearing strength and sliding stability of the fixing bracket 200 .

[0050] In some embodiments of the present invention, a connecting hole is provided on the fixed bracket 200 for inserting screws or bolts. Specifically, the first bracket can be fixed to the slide rail 300 by inserting bolts or screws connected to the slide rail 300 through the connecting hole, and the second bracket can be directly fixed to the wall by inserting bolts or screws connected to the wall through the connecting hole.

[0051] In some embodiments of the present invention, Figure 2 , Figure 3 , Figure 7 as well as Figure 8 As shown, each group of snap-fitting parts is provided with at least two second snap-fitting parts 204 on both sides of the fixed bracket 200, and the second snap-fitting parts 204 are used to snap-fit ​​the corresponding first snap-fitting parts 102. Obviously, according to this structure, as long as there are second snap-fitting parts 204 on both sides of the fixed bracket 200 that snap-fit ​​the two groups of first snap-fitting parts 102, the installation between the fixed bracket 200 and the mounting position 101 can be achieved. Therefore, at least one side of the fixed bracket 200 needs to have a second snap-fitting part 204 that snaps the first snap-fitting part 102, and at least two second snap-fitting parts 204 are needed on both sides.

[0052] In some embodiments of the present invention, Figure 2 , Figure 3 , Figure 7 as well as Figure 8 As shown, when each group of second fastening members 204 is fastened with the first fastening members 102, the projection width in the vertical direction is adapted to the projection width of the two groups of first fastening members 102 in the vertical direction, that is, it is necessary to make each group of second fastening members 204, when fastening with the first fastening members 102, enable the fixing bracket 200 to be stably fastened and installed in the installation position 101, thereby ensuring that the module box body 100 and the fixing bracket 200 cannot slip out forward and backward, thereby achieving their stable fastening.

[0053] In some embodiments of the present invention, when each group of second fastening members 204 fastens the first fastening members 102, that is, the second fastening members 204 on both sides for fastening can fit the two opposite inner walls of the installation position 101 and the bottom plate of the installation position 101. At the same time, the uppermost end of the fixed bracket 200 can also fit the inner wall of the upper end (or upper side) of the installation position, thereby fully ensuring the stability of the module box body 100 when it is installed on the fixed bracket 200.

[0054] In some embodiments of the present invention, in the above structure, a friction damping structure is provided on the surface of the first fastening member 102, the inner wall of the mounting position 101 and the bottom plate, thereby increasing the friction resistance when the second fastening member 204 slides and fastens the first fastening member 102, thereby improving the connection stability between the module box body 100 and the mounting position 101.

[0055] In some embodiments of the present invention, the friction damping structure may be configured as a friction pattern or a nylon surface to fully increase the friction resistance.

[0056] In some embodiments of the present invention, Figure 2 , Figure 3 , Figure 4 as well as Figure 5 As shown, the fixed bracket 200 is provided with a horizontal rectangular fixing plate, and the two sides of each top corner of the rectangular fixing plate are provided with a second buckling piece 204. Obviously, according to the figure, the rectangular fixing plate provided here is a square fixing plate, and two groups of buckling parts are correspondingly provided. Each group of buckling parts is provided with four identical second buckling parts 204 on both sides of the fixed bracket 200, one group of buckling parts can realize the vertical suspension of the module box body 100, so as to facilitate the technician to carry out the lower side wiring, and after rotating 90° (or 270°), the module box body 100 can be installed horizontally through another group of buckling parts, which is convenient for the technician to carry out the right side wiring (or left side wiring). Furthermore, when the fixed plate here is not an equilateral square structure, in order to ensure that the fixed bracket 200 can be smoothly installed after rotation, it is necessary to make the second buckling piece 204 after rotation able to adapt to the buckling of the first buckling piece 102.

[0057] In some embodiments of the present invention, Figure 6 As shown, four first buckling members 102 are provided, and the four first buckling members 102 are evenly distributed on two opposite inner side walls of the installation position 101, so as to fully improve the installation stability when the module box body 100 is buckled with the fixing bracket 200.

[0058] In some embodiments of the present invention, Figure 2 , Figure 3 , Figure 4 as well as Figure 5 As shown, the first fastening member 102, the second fastening member 204, the third fastening member and the fourth fastening member are all configured as horizontal stoppers.

[0059] In some embodiments of the present invention, Figure 1 , Figure 6As shown, the module box body 100 is provided with an installation cavity 103 with an opening at one end, so that a wiring port for convenient wiring and a module component 104 (such as a control box and other structures) that is easy to install and can be disassembled can be formed. In combination with the above-mentioned installation structure, its multi-angle buckled multi-mode installation mainly refers to the diversity of wiring directions. For example, after the module box body 100 is vertically suspended on the fixed bracket 200, it is convenient for technicians to connect wires from the bottom, or in specific occasions, it is necessary to make the module box body 100 horizontally installed to the left or right relative to the fixed bracket 200, so that technicians can connect wires from the left or right side. There are even some specific situations, such as when the module box is set under the aisle, it is necessary to facilitate technicians to connect wires from the top.

[0060] In some embodiments of the present invention, the structure of the entire mounting position 101 can be further set as a rotating structure, so that the module box body 100 can be further rotated relative to the fixed bracket 200, thereby obtaining an installation structure that is more suitable for actual installation conditions. Specifically, a rotating seat can be rotatably set on the rear side of the module box body 100, and the mounting position 101 and its related structures are all set on the rotating seat.

[0061] In some embodiments of the present invention, Figure 7 As shown, in order to facilitate technical personnel to understand the technical solution of the present application, different from the above technical solution, another fixing bracket 200 is provided here. Combined with the figure, it can be seen that the main structure of the fixing bracket 200 here is a regular hexagonal fixing plate, and three sets of buckling parts are arranged on its peripheral side. Figure 7 In the fastening state shown, the first group of fastening parts that fasten the first fastening piece 102 are provided with four second fastening pieces 204 on both sides of the fixed bracket 200. The fixed bracket 200 is rotated 60° clockwise and then fastened through the second group of fastening parts. The second group of fastening parts is provided with three second fastening pieces 204, which can also achieve stable fastening. Further, the fixed bracket 200 is further rotated 60° clockwise and fastened through the third group of fastening parts. The third group of fastening parts is also provided with three second fastening pieces 204 to fasten the corresponding first fastening pieces 102, which can also achieve stable fastening.

[0062] In some embodiments of the present invention, Figure 8As shown, different from the above technical solution, another structure of a fixing bracket 200 and another mounting position 101 is provided here. Combined with the figure, it can be seen that each group of first fastening members 102 is only provided with one first fastening fastening member 102, and correspondingly, the rectangular fixing bracket 200 is provided with two groups of fastening parts. The first group of fastening parts that fasten the first fastening member 102 is correspondingly provided with two a-type second fastening members 204a. The fixing bracket 200 is rotated 90° clockwise and the second group of fastening parts is fastened with the first fastening member 102. The second group of fastening parts is correspondingly provided with two b-type second fastening members 204b. Although the sizes of the a-type second fastening member 204a and the b-type second fastening member 204b are different, they are both adapted to the first fastening member 102, so they can play the same stable fastening effect.
