Description

Technical Field

[0001] The invention relates to the technical field of electrical machinery, and in particular to a mounting device. Background Art

[0002] As an important metering device, the use of electric meters is becoming more and more widespread. With the transformation of the national power grid, power grid companies have begun to vigorously promote smart grids, which has greatly increased the use of electric energy meters and meter boxes. Therefore, the installation and stable operation of electric meters are important factors. The voltage transformer and the current transformer are first connected to the electric meter plug-in by wires, and then electrically connected to the electric energy meter through the electric meter plug-in. The prior art first connects and disconnects the voltage transformer and the current transformer through bolts and conductive sheets to control the disconnection and short circuit, and then disconnects and connects the electric meter plug-in with the voltage meter. For example, the connection of the bolts and the conductive sheets requires the voltage transformer to be disconnected and the current transformer to be short-circuited, and then the electric meter plug-in is connected to the voltage meter. The above method has the following problems:

[0003] 1. The process of fixing the conductive sheet and the wire with bolts is cumbersome and complicated. When wrong connection or missed connection occurs, the electric meter and the electric plug-in are connected under power, causing the parts such as the voltage transformer and the current transformer to burn out.

[0004] 2. You need to connect the bolts and the conductive sheet first, and then connect the meter plug-in and the meter. The whole installation process is very complicated.

[0005] 3. The pusher and ball that push the meter plug-in to expand have an erroneous swing due to no limit during sliding, causing the ball to get stuck on the meter plug-in.

[0006] 4. The joint junction box and the frame carrying the electric meter are separately arranged, resulting in a large space occupied by the assembly device of the electric meter. Summary of the invention

[0007] In order to solve the technical problem that the process of bolting the conductive sheet and the wire in the prior art is cumbersome and complicated, and when there is a wrong connection or missing connection, the electric meter and the electric plug are connected under power, resulting in the burning of parts such as the voltage transformer and the current transformer, the present invention provides a mounting device to solve the above technical problem.

[0010] According to one embodiment of the present invention, the pushing portion and the force-bearing portion are both configured to be conical spherical, and when the first driving rod drives the voltage connecting piece to disconnect the electrical connection with the fastener, the second driving rod drives the current connecting piece to synchronously form an electrical connection with the fastener.

[0011] According to one embodiment of the present invention, connecting plates are formed on both sides of the first driving rod and the second driving rod, and the two connecting plates are arranged in parallel to form an avoidance channel. The fastener extends into the avoidance channel, and a plug-in channel is formed on the support frame. The plug-in channel and the avoidance channel are connected, and an external wiring terminal is inserted into the plug-in channel and abutted by the fastener, so that an external device and the voltage connector and the current connector are electrically connected.

[0012] According to one embodiment of the present invention, a limiting slide corresponding to the connecting plate is formed on the support frame, the connecting plate passes through the limiting slide and is connected to the voltage connecting piece and the current connecting piece, and the fastener is assembled between the two connecting plates.

[0013] According to one embodiment of the present invention, the connecting rod assembly includes: at least one first connecting rod, one end of which is fixedly connected to the driving part of the driving member; at least one second connecting rod, one end of which is hingedly matched with the other end of the first connecting rod; a linkage rod, both ends of which are rotatably assembled on the supporting frame, and the linkage rod is passed through a hinge ring formed on the first driving rod and the second connecting rod, so that the linkage rod and the second connecting rod and the first driving rod are hingedly matched.

[0014] According to an embodiment of the present invention, an avoidance groove is formed on the supporting frame, and the hinge between the first connecting rod and the second connecting rod performs a limited deflection action in the avoidance groove.

Compared with the prior art, the process of bolting conductive sheets and wires is cumbersome and complicated, and when there is a wrong connection or missing connection, the electric meter and the electrical plug-in are connected under power, resulting in the burning of parts such as the voltage transformer and the current transformer. In the present application, the connection between the voltage connecting piece, the current connecting piece and the fastener and the connection between the plug-in expansion member and the electric meter are carried out synchronously under the action of the driving member, thereby avoiding the connection between the plug-in expansion member and the electric meter when the voltage connecting piece, the current connecting piece and the fastener are wrongly connected or missed.

[0020] 2. A limiting slide corresponding to the connecting plate is formed on the supporting frame of the present application.

The fasteners are assembled between the two connecting plates to prevent the supporting frame from interfering with the movement of the voltage connecting piece and the current connecting piece. At the same time, the supporting frame can also limit the movement of the voltage connecting piece and the current connecting piece.

[0021] 3. Connecting plates are formed on both sides of the first driving rod and the second driving rod of the present application. The two connecting plates are arranged in parallel to form an avoidance channel. The fastener extends into the avoidance channel. A plug-in channel is formed on the supporting frame.

[0022] 4. At least one limiting dovetail groove is formed on the inner wall of the expansion part of the plug-in expansion member of the present application, and a limiting protrusion corresponding to the limiting dovetail groove is formed on the pushing member, and the limiting protrusion extends into the limiting dovetail groove, thereby avoiding erroneous deflection of the push block during the sliding process, thereby ensuring that the push block will not be stuck in the expansion part, so that the device can operate stably for a long time.

DETAILED DESCRIPTION

[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present application. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, it indicates the presence of features, steps, operations, devices, components and / or combinations thereof.

[0038] Unless otherwise specifically stated, the relative arrangement of the parts and steps described in these embodiments, numerical expressions and numerical values ​​do not limit the scope of the present invention. At the same time, it should be understood that, for ease of description, the sizes of the various parts shown in the accompanying drawings are not drawn according to the actual proportional relationship. The technology, method and equipment known to ordinary technicians in the relevant field may not be discussed in detail, but in appropriate cases, the technology, method and equipment should be regarded as a part of the authorization specification. In all examples shown and discussed here, any specific value should be interpreted as being merely exemplary, rather than as a limitation. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters represent similar items in the following drawings, so once a certain item is defined in an accompanying drawing, it does not need to be further discussed in subsequent drawings.

[0039] In the description of the present invention, it is necessary to understand that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the devices or elements referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present invention. The directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

[0040] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0041] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. If not otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the present invention.

[0042] like Figure 1-12 As shown, an installation device of this embodiment is used for plugging and cooperating with an electric meter 9 and carrying and installing the electric meter 9. The installation device includes a carrier frame 1, a plug-in expansion member 2, a first drive rod 31, a second drive rod 32 and an elastic member 4. The carrier frame 1 carries the electric meter 9, and the plug-in expansion member 2 is assembled on the carrier frame 1. The first drive rod 31 is connected to a voltage connecting piece 81. The first drive rod 31 is driven by the drive member 5 to move along the first installation channel 11 of the carrier frame 1 with the help of a connecting rod assembly 6, so that the voltage connecting piece 81 and the fastener 83 form an electrical connection. At the same time, the drive member 5 drives the plug-in expansion member 2 to expand to form an electrical connection with the electric meter 9. The second drive rod 32 is connected to a current connecting piece 82. The second drive rod 32 is slidably assembled in the second installation channel 12 of the carrier frame 1. The movement of the first drive rod 31 drives the second drive rod 32 to move synchronously, so that the current connecting piece 82 and the fastener 83 form an electrical connection. The elastic member 4 is assembled in the second installation channel 12, and the elastic member 4 provides a reset force for the reset of the second drive rod 32.

[0043] It can be seen from the above content that the connection action of the voltage connector 81, the current connector 82 and the fastener 83 and the connection action of the plug-in expansion piece 2 and the electric meter 9 in this embodiment are performed synchronously under the action of the driving member 5, that is, the two connection actions are not performed separately. This can avoid the re-connection action of the plug-in expansion piece 2 and the electric meter 9 in the case where the voltage connector 81, the current connector 82 and the fastener 83 are misconnected or missed, thereby preventing parts such as the voltage transformer and the current transformer from being burned.

[0044] The support frame 1 of this embodiment carries the electric meter 9. Specifically, a accommodating space is formed on the support frame 1. The electric meter 9 slides along the guide rail on the support frame 1 to the accommodating area, and the connecting part, i.e., the connecting hole, thereon slides into the plug-in expansion member 2, thereby being carried by the support frame 1 and the plug-in expansion member 2.

[0045] The driving member 5 of this embodiment drives the first driving rod 31 to reciprocate through the connecting rod assembly 6. Specifically, the driving member 5 and the carrier 1 are rotatably assembled. The connecting rod assembly 6 includes at least one first connecting rod 61, at least one second connecting rod 62 and a linkage rod 63. In this embodiment, the first connecting rod 61 and the second connecting rod 62 are both provided in two pieces. The two first connecting rods 61 are fixedly connected to the two ends of the driving member 5. In this way, when the driving member 5 deflects, the first connecting rod 61 will rotate with it. The other end of the first connecting rod 61 is formed with an installation opening 611, and one end of the second connecting rod 62 extends into the installation opening 611. A latch or a rotating shaft is passed through the first connecting rod 61. The first connecting rod 61 and the second connecting rod 62 are on the first connecting rod 61 and the second connecting rod 62, so that the first connecting rod 61 and the second connecting rod 62 are hingedly matched, and the two ends of the linkage rod 63 are rotatably assembled on the support frame 1 so that the linkage rod 63 is limited by the support frame 1, and the linkage rod 63 is passed through the hinge ring 64 formed on the first drive rod 31 and the second connecting rod 62, so that the linkage rod 63, the second connecting rod 62 and the first drive rod 31 are hingedly matched, so that the yaw movement of the driving member 5 will drive the first drive rod 31 to move, and at the same time, the two ends of the linkage rod 63 are subjected to symmetrical thrusts, which can easily drive all the first drive rods 31 thereon to move synchronously.

[0046] In order to prevent the supporting frame 1 from interfering with the swing of the first connecting rod 61, the hinge between the first connecting rod 61 and the second connecting rod 62 of this embodiment is located in the avoidance groove 16 on the supporting frame 1. In this embodiment, the width of the avoidance groove 16 is slightly larger than the width of the first connecting rod 61. When the first connecting rod 61 swings, the first connecting rod 61 can be limited to prevent the first connecting rod 61 from rotating incorrectly.

[0047] The driving member 5 of this embodiment drives the first driving rod 31 to move, and at the same time uses the linkage component 7 to make the expansion part 23 of the plug-in expansion member 2 expand so as to be connected with the electric meter 9. Specifically, the linkage component 7 includes a linkage spring 71, a linkage ball 72 and a linkage driving rod 73. The linkage spring 71 is arranged in the third installation channel 21 of the plug-in expansion member 2, and one end of the linkage spring 71 abuts on the push block 74 in the third installation channel 21. The linkage ball 72 is also arranged in the third installation channel 21. The other end of the linkage spring 71 abuts on the linkage ball 72. The linkage driving rod 73 carries and drives the linkage ball 72. The non-driving end of the linkage driving rod 73 is limited by the driving part 51 of the driving member 5. The driving member 5 drives the linkage driving rod 73 to move along the movement direction of the vertical push block 74, so that the linkage driving rod 73 pushes the linkage ball 72 to roll along the vertical direction. The movement of the linkage ball 72 compresses the linkage spring 71, so that the linkage spring 71 can drive the push block 74 to move along the vertical direction to squeeze the expansion part 23 of the plug-in expansion member 2 to open.

[0048] In addition, the linkage drive rod 73 of the present embodiment is limited by the drive member 5. Specifically, the driving end of the linkage drive rod 73 is inserted into the avoidance hole on the plug-in expansion member 2, and the avoidance hole is connected to the third installation channel 21. The non-driving end of the linkage drive rod 73 is maintained against the driving part 51 of the drive member 5 under the elastic force of the linkage spring 71 and the gravity of the linkage ball 72, and the driving part 51 and the linkage drive rod 73 are rollingly matched in the present embodiment to reduce the friction between the two.

[0049] The push block 74 of the present embodiment is limited in its sliding movement within the plug-in expansion member 2. Specifically, at least one limiting dovetail groove 22 is formed on the inner wall of the expansion portion 23 of the plug-in expansion member 2. In the present embodiment, four limiting protrusions 741 corresponding to the limiting dovetail groove 22 are formed on the push block 74. The limiting protrusions 741 extend into the limiting dovetail groove 22. In this way, the push block 74 is limited when sliding along the limiting dovetail groove 22. In other words, the push block 74 cannot shake arbitrarily during sliding, thereby preventing the push block 74 from getting stuck in the expansion portion 23.

[0050] Preferably, the driving part 51 of the driving member 5 of this embodiment is configured as an eccentric wheel, and a plurality of U-shaped mounting parts are formed on the carrier frame 1. The eccentric wheel rotates with the mounting part by means of a rotating shaft. In this embodiment, the driving member 5 is configured as a wrench shape so that the operator can apply force.

[0051] The first driving rod 31 of this embodiment drives the voltage connecting piece 81 to be disconnected from the fastener 83, and drives the second driving rod 32 to move, so that the current connecting piece 82 and the fastener 83 are synchronously connected. Specifically, under the action of the linkage rod 63, the first driving rod 31 moves away from the linkage rod 63 with the voltage connecting piece 81, so that the U-shaped connecting portion 84 on the voltage connecting piece 81 is out of contact with the fastener 83, so that the voltage connecting piece 81 is in a power-off state. When the first driving rod 31 moves, the pushing portion 311 on the first driving rod 31 applies a force to the force-bearing portion 321 on the second driving rod 32, thereby pushing the second driving rod 32 to move with the current connecting piece 82 toward the elastic member 4, so that the U-shaped connecting portion 84 on the current connecting piece 82 is in contact with the fastener 83, so that the current connecting piece 82 is electrically connected to the fastener 83. In this embodiment, the elastic member 4 is configured as a reset spring, and the reset spring provides a reset force so that the current connecting piece 82 needs to be disconnected from the fastener 83.

[0052] In this embodiment, the first installation channel 11 and the second installation channel 12 are vertically arranged, and an avoidance opening 111 is formed on the first installation channel 11. The force-bearing portion 321 of the second driving rod 32 exits the first installation channel 11 through the avoidance opening 111 under the action of the pushing portion 311, and extends into the first installation channel 11 through the avoidance opening 111 under the action of the elastic member 4.

[0053] Preferably, the pushing portion 311 and the force-bearing portion 321 of this embodiment are both configured to be conical spherical, so that the first driving rod 31 can more easily push the second driving rod 32 to move.

[0054] In this embodiment, the first driving rod 31 and the second driving rod 32 are connected to the voltage connecting piece 81 and the current connecting piece 82 by means of a connecting plate 33. Specifically, connecting plates 33 are formed on both sides of the first driving rod 31 and the second driving rod 32. The connecting plates 33 are arranged along the axial direction perpendicular to the first mounting channel 11 and the second mounting channel 12. A limiting slide 13 corresponding to the connecting plate 33 is formed on the support frame 1. The connecting plate 33 passes through the limiting slide 13 and is connected to the voltage connecting piece 81 and the current connecting piece 82. The fastener 83 is assembled on the support beam 14 on the support frame 1. The support beam 14 carries the voltage connecting piece 81 and the current connecting piece 82. The support beam 14 is located between the two connecting plates 33.

[0055] Furthermore, the two connecting plates 33 of the present embodiment are arranged in parallel to form an avoidance channel 331, and the avoidance channel 331 is located at the bottom of the support beam 14. The fastener 83 passes through the support beam 14 and extends into the avoidance channel 331. A plug-in channel 15 is formed on the support frame 1, and the plug-in channel 15 is connected to the avoidance channel 331. The external wiring terminal is inserted into the plug-in channel 15 and is abutted by the fastener 83, so that the external device and the voltage connector 81 and the current connector 82 are electrically connected.

[0056] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of the present invention.
