Description

Technical Field

[0001] The embodiment of the utility model relates to the field of electrical technology, and in particular to an installation device for a plug-in switch. Background Art

[0002] Switches can close, carry, and interrupt current under normal or abnormal circuit conditions. They are typically installed within a power distribution cabinet using plug-in connections. To ensure reliable contact between the switch and external conductive components, a clamping force must be applied to the switch, making insertion and removal of the switch time-consuming and labor-intensive.

[0003] In the related art, an installation device is usually used to assist in the plugging and unplugging of switches. Depending on the type and size of the switch to be plugged and unplugged, the installation device is provided with a hanging rod adapted thereto, and is also provided with a transmission mechanism for reversing movement. When used, the installation device is connected to the cabinet and adapted to be connected to the switch through the hanging rod. The rotation of the installation device is converted into horizontal movement of the switch through the transmission mechanism to drive the switch to be inserted or unplugged relative to the cabinet.

[0004] However, the mounting device involved in the related art has a hanging rod that is only suitable for a specific type of switch and has poor versatility for different types of switches. Utility Model Content

[0005] The embodiment of the present invention provides a mounting device for a plug-in switch, which can solve the technical problems existing in the related art. Specifically, the technical solution is as follows.

[0006] On the one hand, a mounting device for a plug-in switch is provided, the mounting device of the plug-in switch comprising: a bracket, a supporting mechanism and a connecting mechanism; the bracket comprising: two supporting plates arranged opposite to each other, the connecting mechanism being fixedly connected to the two supporting plates, the supporting mechanism being rotatably connected to the two supporting plates, the supporting mechanism being used to be connected to an assembly of the plug-in switch; the connecting mechanism comprising: a pressure block, the pressure block being used to abut against the plug-in switch when the plug-in switch is inserted into the assembly; the connecting mechanism further comprising: a plurality of pull rod groups, each pull rod group comprising two symmetrically arranged pull rods, the two pull rods being respectively arranged on the surfaces of the two supporting plates, the two pull rods protruding from the surfaces of the support plates in the distribution direction of the two support plates, the protruding directions of the two pull rods being opposite, and the pull rods being used to be connected to the plug-in switch when the plug-in switch is pulled out of the assembly. Wherein, the multiple tie rod groups satisfy at least one of the following conditions: Condition 1: the distances between the multiple tie rods arranged on the same support plate and the rotating shaft of the support mechanism are different from each other; Condition 2: the tie rod distances of at least some of the multiple tie rod groups are different, wherein the tie rod distance is the distance between the two support plates and / or the distance between the protruding ends of the two tie rods of the tie rod group; Condition 3: the distances between at least some of the multiple tie rods arranged on the same support plate and the plane where the pressure block is located are different from each other.

[0007] By providing multiple lever assemblies and ensuring that the multiple lever assemblies meet at least one of conditions 1, 2, and 3, the embodiments of the present invention can adapt to plug-in switches of different sizes and types. For example, plug-in switches with different heights, widths, and thicknesses can be connected using different lever assemblies. This effectively improves the versatility of the plug-in switch mounting device for different types of switches, making it compatible with different types of plug-in switches. This reduces the number and types of mounting devices used during plug-in switch assembly, making operation more convenient and reducing costs.

[0008] In some possible implementations, the support plate includes a first support plate segment, a bent plate segment, and a second support plate segment connected in sequence. The spacing between the first support plates of the two support plates is different from the spacing between the second support plate segments of the two support plates. Some of the multiple pull rods provided on the same support plate are connected to the first support plate segment, while the remaining pull rods are connected to the second support plate segment. This implementation allows the mounting device to be adapted for plug-in switches of varying widths.

[0009] In some possible implementations, the two support plates include outer surfaces and opposing inner surfaces in the distribution direction, and some of the multiple tie rods disposed on the same support plate are connected to the outer surfaces of the support plate, while the remaining tie rods are connected to the inner surfaces of the support plate. This implementation allows the mounting device to be adapted for plug-in switches of varying widths.

[0010] In some possible implementations, the support plate is provided with an extension plate on one or both sides, perpendicular to the plane on which the pressure block is located. Some of the multiple tie rods provided on the same support plate are connected to the support plate, while the remaining tie rods are connected to the extension plate. This implementation allows the mounting device to be adapted for plug-in switches of varying thicknesses.

[0011] In some possible implementations, the support plate has a plurality of tie rod connection structures, the tie rod connection structures are used to connect the tie rods, and the number of the tie rod connection structures is greater than or equal to the number of the tie rods.

[0012] By making the number of pull rod connection structures greater than the number of pull rods, new pull rods can be adaptively connected to the pull rod connection structures in an empty state according to the specific type of plug-in switch, thereby further improving the adaptability of the installation device to different types of plug-in switches.

[0013] In some possible implementations, the pressure block is connected between the two support plates; the pressure block has an avoidance groove, which is used to accommodate the operating handle of the plug-in switch; the surface of the pressure block facing the plug-in switch has two groups of protrusions, and the two groups of protrusions are respectively located on both sides of the avoidance groove, and the protrusions are used to abut against the plug-in switch.

[0014] Through this technical solution, the pressing block rationally utilizes the gap between the two support plates, which is conducive to making the structure of the installation device compact and the volume miniaturized.

[0015] In some possible implementations, the support mechanism includes: a support shaft and a plurality of connecting rods, the support shaft is rotatably connected between the two support plates, and the plurality of connecting rods are connected to the support shaft; the plurality of connecting rods are spaced apart along the thickness direction of the support plate, and the end of the connecting rod facing away from the support shaft is used to connect to the assembly of the plug-in switch.

[0016] By fixing the connecting rod to the support shaft, the rotation centerline of the support shaft is on the same horizontal plane as the fixing point of the connecting rod and the assembly, so that the handle can be operated and the force can be transmitted to the plug-in switch to insert or remove it from the assembly.

[0017] In some possible implementations, the support shaft has a first stop on a side facing away from the assembly of the plug-in switch, and a second stop is provided on the support plate. The first stop cooperates with the second stop to limit the rotation angle of the bracket.

[0018] This technical solution limits the rotation angle of the bracket during the plug-in switch insertion operation, preventing the plug-in switch from being over-inserted and causing wear. It also limits the rotation angle of the bracket during the plug-in switch removal operation, preventing the plug-in switch from colliding with the mounting device and causing damage.

[0019] In some possible implementations, a surface of the pressure block facing the plug-in switch has multiple locking structures, and the multiple locking structures correspond one-to-one to the multiple connecting rods. The locking structures are used to lock the connecting rods in the storage state to ensure that the connecting rods are stably placed in the storage state.

[0020] In some possible implementations, the locking structure is an elastic locking block having a locking slot and an opening connected to the locking slot, wherein the opening allows the connecting rod to enter and exit the locking slot, and the locking slot is used to lock the connecting rod.

[0021] The above design of the locking structure can provide a stronger locking force for the connecting rod and is easy to operate, and the user can operate it with one hand. BRIEF DESCRIPTION OF THE DRAWINGS

[0050] In the description of the embodiments of the present invention, it should be understood that the terms "upper", "lower", "inside", "outside", "length", "thickness", "width", etc. indicating the orientation or position relationship are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the embodiments of the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. When the product is placed in different postures, the orientation may change, and therefore it cannot be understood as a limitation on the embodiments of the present invention.

[0051] Switches can close, carry, and interrupt current under normal or abnormal circuit conditions. They are typically installed within the distribution cabinet using plug-in connections. For example, a circuit breaker is typically installed inside the distribution cabinet. Clamping contacts ensure reliable contact between the circuit breaker and external conductive components, making insertion and removal of the circuit breaker time-consuming and labor-intensive.

[0052] Related art installation devices for pluggable switches typically use a mounting rod adapted to the type and size of the switch being plugged in. However, these mounting rods are designed for specific switch types and lack versatility across different switch types. Different types of switches typically require separate mounting devices, resulting in a large variety of tools and inconvenient storage and operation. The different types of switches described in the present invention can also be considered switches of different frame sizes.

[0053] In view of the technical problems existing in the related art, the embodiment of the present invention provides an installation device 100 for a plug-in switch. Figure 1 The structure of the installation device 100 is illustrated in FIG. Figure 1 As shown, the mounting device 100 comprises: a bracket 1, a supporting mechanism 2 and a connecting mechanism 3. The bracket 1 comprises: two supporting plates 12 arranged opposite to each other, the supporting mechanism 2 is rotatably connected to the two supporting plates 12, and the supporting mechanism 2 is used to connect to the assembly 300 of the plug-in switch 200 (see Figure 3 and Figure 4 ). The connecting mechanism 3 is fixedly connected to the two support plates 12, as shown in the attached Figure 1 As shown, the connecting mechanism 3 includes: a pressure block 31 and multiple pull rod groups, each pull rod group includes two symmetrically arranged pull rods 32, the two pull rods 32 are respectively set on the surfaces of the two support plates 12, and the two pull rods 32 protrude from the surface of the support plates 12 in the distribution direction of the two support plates 12, and the protruding directions of the two pull rods 32 are opposite.

[0054] Figure 1 32-a, 32-b, 32-c in the figure all refer to the pull rod 32, and the letters a, b, and c are used to distinguish the pull rod 32 at different positions. The pressing block 31 is used to abut against the plug-in switch 200 when the plug-in switch 200 is inserted into the assembly 300 (see Figure 3 ), the pull rod 32 is used to connect to the plug-in switch 200 when the plug-in switch 200 is pulled out of the assembly 300 (see Figure 4 ).

[0055] It should be noted that the "plug-in switch 200" involved in the embodiment of the present invention refers to a switch 200 device that can be assembled by plugging in and unloaded by pulling out. An example of the plug-in switch 200 may be a circuit breaker, etc. Figure 4 , usually, two hooks 201 are provided at the end of the plug-in switch 200, accordingly, Figure 1 The example shows that each pull rod group includes two pull rods 32 that are symmetrical and spaced apart on both sides of the bracket 1. Therefore, the installation device 100 is connected to the two hooks 201 of the plug-in switch 200 based on the two pull rods 32 of the specific pull rod group, thereby realizing the connection between the installation device 100 and the plug-in switch 200, so as to facilitate the use of the installation device 100 to pull out the plug-in switch 200, and prevent the plug-in switch 200 from shaking when being pulled by the pull rod 32, thereby improving the movement stability.

[0056] The "assembly 300 of the plug-in switch 200" involved in the embodiment of the present invention refers to a device that provides an assembly space for the plug-in switch 200, which can be: a cabinet or a plug-in frame of a distribution cabinet or distribution box. Figure 11 The end of the assembly body 300 has a mounting hole 301 for connecting with the supporting mechanism 2 of the mounting device 100.

[0057] The working principle of the installation device 100 of the plug-in switch provided by the embodiment of the present invention is as follows:

[0058] As attached Figure 3As shown, when the switch 200 needs to be inserted into its assembly 300, the support mechanism 2 of the installation device 100 is connected to the assembly 300 of the plug-in switch 200, and at the same time, the pressing block 31 of the connection mechanism 3 of the installation device 100 is abutted against the plug-in switch 200. Since the support mechanism 2 is rotatably connected to the bracket 1, the user applies force to the bracket 1, causing the bracket 1 to rotate relative to the assembly 300 in the first direction ( Figure 3 The free end of the bracket 1 is shown to move in a direction opposite to the insertion direction of the plug-in switch 200. Since the connecting mechanism 3 is fixedly connected to the bracket 1, the rotating bracket 1 drives the pressing block 31 to move toward the assembly 300 ( Figure 3 The movement direction of the pressing block 31 is shown to be the same as the insertion direction of the plug-in switch 200, so that the pressing block 31 drives the plug-in switch 200 to be inserted into the assembly 300. Subsequently, the connection between the supporting mechanism 2 and the assembly 300 can be released.

[0059] As attached Figure 4 As shown, when the switch 200 needs to be pulled out from its assembly 300, the support mechanism 2 of the installation device 100 is connected to the assembly 300 of the plug-in switch 200, and at the same time, the pull rod 32 of the connection mechanism 3 is connected to the plug-in switch 200. The user applies force to the bracket 1, so that the bracket 1 rotates in the opposite direction relative to the assembly 300 along the second direction ( Figure 4 The free end of the bracket 1 is shown to move in a direction opposite to the direction of removal of the plug-in switch 200), wherein one of the first direction and the second direction is clockwise and the other is counterclockwise. In this process, the bracket 1 rotates in the opposite direction and drives the pull rod 32 to move in a direction away from the assembly 300 ( Figure 4 In the example, the movement direction of the pressing block 31 is the same as the removal direction of the plug-in switch 200. Thus, the pressing block 31 pulls the plug-in switch 200 out of the assembly 300. Subsequently, the connection between the support mechanism 2 and the assembly 300 is released, and the connection between the pull rod 32 and the plug-in switch 200 is released.

[0060] It can be seen that the installation device 100 of the plug-in switch provided in the embodiment of the present invention can assist in the plugging and unplugging of the plug-in switch 200. Compared with manually plugging and unplugging the switch 200, using the installation device 100 to plug and unplug the switch 200 has the advantages of convenient operation and high efficiency.

[0061] The installation device 100 of the plug-in switch provided in the embodiment of the present invention is further combined with Figure 2Each tie rod group includes two tie rods 32 symmetrically distributed on the two support plates 12 of the bracket 1. In particular, the multiple tie rod groups meet at least one of the following conditions: Condition 1: The spacing between the multiple tie rods 32 arranged on the same support plate 12 and the rotation axis of the support mechanism 2 is different from each other; Condition 2: The tie rod spacing of at least some of the multiple tie rod groups is different, wherein the tie rod spacing is the spacing between the two support plates 12 and / or the spacing between the protruding ends of the two tie rods 32 of the tie rod group. Condition 3: The spacing between at least some of the multiple tie rods 32 arranged on the same support plate 12 and the plane where the pressure block 31 is located is different from each other.

[0062] Condition 1 defines that the distances between the plurality of tie rods 32 connected to the same support plate 12 and the rotation axis of the support mechanism 2 are different from each other, so that the plurality of tie rods 32 are spaced apart along the length direction of the support plate 12, wherein the length direction of the support plate 12 can be seen from FIG. Figure 1 The Y-axis direction in the figure. The multiple pull rods 32 are respectively adapted to those plug-in switches 200 with different height dimensions. For example, after the support mechanism 2 is fixedly connected to the assembly 300 (such as a power distribution cabinet), the position of the support mechanism 2 is fixed. The smaller the height dimension of the plug-in switch 200 to be installed on the assembly 300, the smaller the distance between the pull rod connection position of the plug-in switch 200 and the support mechanism 2. Therefore, the pull rod 32 adapted to the pull rod connection position of the plug-in switch 200 is also correspondingly smaller in distance from the rotation axis of the support mechanism 2. It can be seen that when the distance between the pull rod 32 and the rotation axis of the support mechanism 2 is smaller, it is suitable for connecting to a plug-in switch 200 with a smaller height dimension. Conversely, when the distance between the pull rod 32 and the rotation axis of the support mechanism 2 is smaller, it is suitable for connecting to a plug-in switch 200 with a smaller height dimension.

[0063] Condition 2 defines that at least some of the tie rod groups in the plurality of tie rod groups have different tie rod spacings, which is the spacing between two support plates 12 and / or the spacing between the protruding ends of two tie rods 32 in the tie rod group.

[0064] The two support plates 12 include outer surfaces and opposing inner surfaces in the distribution direction. That is, the outer surfaces of the support plates 12 are the surfaces of the two support plates 12 facing away from each other, and the inner surfaces of the support plates 12 are the surfaces of the two support plates 12 facing each other. For the tie rod group arranged on the outer surface of the support plate 12, the corresponding tie rod spacing is the spacing between the two support plates 12. For the tie rod group arranged on the inner surface of the support plate 12, the corresponding tie rod spacing is the spacing between the protruding ends of the two tie rods 32 in the current tie rod group.

[0065] For example, a smaller distance between the pull rods means a smaller distance between the two pull rod connection points of the plug-in switch 200, i.e., a narrower plug-in switch 200. Conversely, a larger distance between the pull rods means a larger distance between the two pull rod connection points of the plug-in switch 200, i.e., a wider plug-in switch 200. Therefore, by making the pull rod distances of at least some pull rod groups different, plug-in switches 200 of different widths can be accommodated.

[0066] Regarding condition three, the distances between at least some of the multiple tie rods 32 and the plane containing the pressure block 31 differ from one another. Since the pressure block 31 needs to abut the plug-in switch 200, the distances between at least some of the tie rods 32 and the plane containing the pressure block 31 differ, meaning that the distances between at least some of the tie rods 32 and the plug-in switch 200 also differ. When the thickness of the plug-in switch 200 (the dimension along the plug-in direction) is large, the closer the plug-in switch 200 is to the mounting device, the tie rods 32 farther from the plug-in switch 200 are used to connect to it. Conversely, when the thickness of the plug-in switch 200 is small, the farther the plug-in switch 200 is from the mounting device, the tie rods 32 closer to the plug-in switch 200 are used to connect to it. Therefore, condition three enables the multiple tie rods 32 to adapt to plug-in switches 200 of varying thicknesses.

[0067] In summary, the embodiments of the present invention provide multiple lever groups, and ensure that the multiple lever groups meet at least one of conditions one, two, and three. Thus, the multiple lever groups can adapt to plug-in switches 200 of different sizes and types. For example, plug-in switches 200 with different heights, widths, and thicknesses can be connected via different lever groups. This effectively improves the versatility of the plug-in switch mounting device 100 for different types of switches 200, making it compatible with different types of plug-in switches 200. This reduces the number and types of mounting devices 100 used when assembling the plug-in switches 200, making operation more convenient and reducing costs.

[0068] In combination with the structure of the bracket 1 , the positional arrangement of the plurality of tie rod groups on the bracket 1 is further described below as an example.

[0069] Attachment Figure 2 The structure of the bracket 1 is illustrated in FIG. Figure 2 As shown, the bracket 1 includes a handle 11 and two support plates 12 arranged at intervals, and both ends of the handle 11 are respectively connected to the first ends of the two support plates 12.

[0070] The user can apply force to the bracket 1 by holding the handle 11 so that the bracket 1 can be switched between the insertion position and the extraction position.

[0071] The support plate 12 can be a straight plate, a curved plate, or a combination of a straight plate and a curved plate. Figure 2 The example shows a support plate 12 comprising a connected straight plate segment and a curved plate segment, with the support mechanism 2 and the connecting mechanism 3 both connected to the straight plate segment of the support plate 12, and the handle 11 connected to the end of the curved plate segment of the support plate 12. The support plate 12 adopts a structure combining straight and curved plates, which is more ergonomically designed, not only facilitating the effortless rotation of the bracket 1, but also facilitating the bracket 1 to more smoothly and efficiently transmit force to the connecting mechanism 3.

[0072] The two tie rods 32 of each tie rod group are connected to the corresponding support plates 12, for example, Figure 2 In the example, one end of the pull rod 32 is vertically connected to the support plate 12 , and the protruding end of the pull rod 32 is suspended in the air so as to cooperate with the hook 201 of the plug-in switch 200 .

[0073] For those tie rod groups that meet the second condition, it can be considered that at least some of the tie rods 32 provided on the same support plate 12 are spaced apart along the thickness direction of the support plate 12, wherein the thickness direction of the support plate 12 is the distribution direction of the two support plates 12, that is, Figure 2 The X-axis direction is shown.

[0074] For those tie rod groups that meet condition 2, as shown in the attached Figure 5 As shown, the support plate 12 can include a first support plate segment 121, a bent plate segment 122, and a second support plate segment 123 connected in sequence. For example, the first support plate segment 121 and the second support plate segment 123 both extend along the length of the support plate 12, and the bent plate segment 122 extends along the thickness of the support plate 12. The spacing between the first support plate segments 121 of the two support plates 12 is different from the spacing between the second support plate segments 123 of the two support plates 12. Of the multiple tie rods 32 provided on the same support plate 12, some are connected to the first support plate segment 121, and the remaining tie rods 32 are connected to the second support plate segment 123.

[0075] For example, Figure 5 , the distance H1 between the two tie rods 32 - a , ie, the distance between the two first support plate segments 121 , is shown as an example, which is larger than the distance H2 between the two tie rods 32 - b , ie, the distance between the second support plate segments 123 .

[0076] The bent plate segment 122 is bent relative to the first support plate segment 121 and the second support plate segment 123 so that the first support plate segment 121 and the second support plate segment 123 are spaced apart in the thickness direction of the support plate 12. Thus, when part of the pull rod 32 is connected to the first support plate segment 121 and the remaining part of the pull rod 32 is connected to the second support plate segment 123, at least part of the pull rod 32 located on the same side of the bracket 1 is finally spaced apart along the thickness direction of the support plate 12 to adapt to those plug-in switches 200 with different width sizes.

[0077] As another example, the Figure 5 As shown, some of the plurality of tie rods 32 provided on the same support plate 12 are connected to the outer surface of the corresponding support plate 12 , and the remaining tie rods 32 are connected to the inner surface of the corresponding support plate 12 .

[0078] For example, Figure 5 The example shows that the pull rod 32-a and the pull rod 32-b are respectively connected to the outer surface of the support plate 12, and the pull rod 32-c is connected to the inner surface of the support plate 12. Obviously, the pull rod spacing H3 of the pull rod group where the two pull rods 32-c are located, that is, the spacing between the protruding ends of the two pull rods 32-c, is different from the pull rod spacing H1 and H2 of the pull rod group where the pull rod 32-a and the pull rod 32-b are located, so that the installation device 100 is suitable for a variety of plug-in switches 200 with different width sizes.

[0079] For those tie rod groups that meet the third condition, it can be considered that at least some of the tie rods 32 provided on the same support plate 12 are spaced apart along the width direction of the support plate 12, wherein the width direction of the support plate 12 is also Figure 2 The Z-axis direction is shown in the attached figure. Figure 6 As shown, the projections of the ends of at least some of the pull rods 32 connected to the same support plate 12 on the reference plane can be distributed at intervals, wherein the reference plane is a plane extending along the width direction of the support plate 12 . Figure 6 In the example, the projections of the ends of the pull rods 32-a and 32-b connected to the support plate 12 on the reference plane are spaced apart, and the projections of the ends of the pull rods 32-c and 32-b connected to the support plate 12 on the second reference plane coincide with each other.

[0080] Based on this implementation plan, as shown in the attached Figure 6As shown, an extension plate 124 can be provided on one or both sides of the support plate 12 along a direction perpendicular to the plane where the pressing block 31 is located. Some of the multiple tie rods 32 provided on the same support plate 12 are connected to the support plate 12, and the remaining tie rods 32 are connected to the extension plate 124. In this way, the multiple tie rods 32 can be distributed at intervals along the width direction of the support plate 12. The number of extension plates 124 can be one or more depending on the actual number of tie rods 32 to be installed.

[0081] It can be seen that, combined with the position distribution scheme of the pull rod 32 on the support plate 12, the installation device 100 is applicable to plug-in switches 200 of various sizes and types, and has strong versatility. It not only reduces the configuration quantity of the installation device 100, but also reduces the assembly cost of the plug-in switch 200.

[0082] In some examples, such as the attached Figure 7 As shown, the support plate 12 has a plurality of tie rod connection structures 13 , which are used to connect the tie rods 32 , and the number of the tie rod connection structures 13 is greater than or equal to the number of the tie rods 32 .

[0083] The position arrangement of the multiple tie rod connection structures 13 on the support plate 12 can also meet at least one of the above conditions 1, 2, and 3, and will not be repeated here.

[0084] By providing multiple tie rod connection structures 13 on the support plate 12 to achieve connection with the tie rods 32, the number of tie rod connection structures 13 can be equal to the number of tie rods 32, or the number of tie rod connection structures 13 can be greater than the number of tie rods 32. In this way, some of the multiple tie rod connection structures 13 are connected to the tie rods 32, while the remaining tie rod connection structures 13 are in an unoccupied state. By leaving some of the tie rod connection structures 13 in an unoccupied state, new tie rods 32 can be adaptively connected to the unoccupied tie rod connection structures 13 according to the specific type of plug-in switch 200, thereby further improving the adaptability of the installation device 100 to different types of plug-in switches 200.

[0085] In the embodiment of the present invention, the connection between the pull rod connection structure 13 and the pull rod 32 can be detachable or non-detachable. Some applicable connection methods can be threaded connection, clamping, riveting, welding, bonding, etc.

[0086] As for the pull rod 32, it can be a common rod form, such as a cylindrical rod. In order to prevent the pull rod 32 from being disengaged from the hook 201 of the plug-in switch 200, a limiting structure can be set at the end of the pull rod 32 away from the support plate 12 to limit the hook 201. For example, the limiting structure can be an annular boss.

[0087] The above is an exemplary description of the arrangement of the tie rod assembly in the connecting mechanism 3 on the bracket 1 . The following is an exemplary description of the arrangement of the pressure block 31 in the connecting mechanism 3 on the bracket 1 .

[0088] In the embodiment of the present invention, the number of the pressing block 31 can be one, for example, a single pressing block 31 can be disposed between the two support plates 12. Alternatively, the number of the pressing blocks 31 can be multiple, for example, two pressing blocks 31 can be provided, and the two pressing blocks 31 are respectively connected to the ends of the support plates 12 away from the handle 11. Figure 1 The example shows that the pressing block 31 is connected between the two support plates 12, and further combined with Figure 3 The fixing pins 34 can be used to securely connect the pressing block 31 to the support plate 12. Furthermore, positioning pins can be provided on both sides of the pressing block 31 to be inserted into positioning holes provided on the support plate 12 for positioning. With this solution, the pressing block 31 effectively utilizes the gap between the two support plates 12, making the mounting device 100 more compact and smaller in size.

[0089] As mentioned above, the support plate 12 includes a first support plate segment 121, a bent plate segment 122 and a second support plate segment 123, so that the pressing block 31 can be located between the two second support plate segments 123. Further, the pressing block 31 is located between the sides of the two support plate segments 12 close to the bent plate segment 122.

[0090] The pressing block 31 is used to abut against the end of the plug-in switch 200. Figure 2 As shown, since the middle area of ​​the end of the plug-in switch 200 is usually convexly provided with an operating handle 202, in order to avoid interference between the operating handle 202 of the plug-in switch 200 and the pressure block 31, Figure 8 The example shows that the pressing block 31 has an avoidance groove 311 to accommodate the operating handle 202 of the plug-in switch 200, thereby avoiding the operating handle 202 and preventing interference.

[0091] For example, the avoidance groove 311 can be provided in the middle region of the pressing block 31 along the width direction of the support plate 12. The avoidance groove 311 can be a through groove or a blind groove. The through groove-type avoidance groove 311 can penetrate both the surface of the pressing block 31 facing the plug-in switch 200 and the surface thereof facing away from the plug-in switch 200. The blind groove-type avoidance groove 311 can penetrate the surface of the pressing block 31 facing the plug-in switch 200 but not the surface thereof facing away from the plug-in switch 200, which helps to improve the strength of the pressing block 31. Along the length direction of the support plate 12, the upper end of the avoidance groove 311 penetrates the upper surface of the pressing block 31, while the lower end of the avoidance groove 311 does not penetrate the upper surface of the pressing block 31. Both of these designs help to improve the strength and structural stability of the pressing block 31.

[0092] Furthermore, Figure 8 It is also illustrated that the surface of the pressure block 31 facing the plug-in switch 200 has two groups of protrusions 312 , which are respectively located on both sides of the avoidance groove 311 . The protrusions 312 are used to abut against the plug-in switch 200 .

[0093] By providing protrusions 312 on both sides of the avoidance groove 311 , the two groups of protrusions 312 are spaced apart along the thickness direction of the support plate 12 . When the plug-in switch 200 is inserted into its assembly 300 , the protrusions 312 abut against the plug-in switch 200 .

[0094] The dimension of the protrusion 312 along the thickness direction of the support plate 12 can be designed to be larger to adapt to plug-in switches 200 of different thicknesses.

[0095] In some examples, such as the attached Figure 8 As shown, the surface of the protrusion 312 facing the pluggable switch 200 has a flat portion 3121 , and the protrusion 312 utilizes the flat portion 3121 to make surface contact with the pluggable switch 200 to increase the contact area and enhance the effect of pushing the pluggable switch 200 into the assembly 300 .

[0096] Based on the above arrangement of the pressing block 31, it can be seen that the length and width of the installation device 100 are independent of the height and width of the switch 200. Under the premise of meeting the usage requirements, the width of the installation device 100 can be designed to be smaller to make it easier to be stored.

[0097] In the embodiment of the present utility model, Figure 10 The support mechanism 2 is positioned on the bracket 1 closer to the handle 11 than the connection mechanism 3. This means that the bracket 1's rotational center is located between the connection mechanism 3 and the handle 11, creating a good lever-type transmission. By abutting the protrusion 312 of the pressure block 31 against the end face of the pluggable switch 200, a force opposite to the insertion direction is applied to the handle 11 to insert the switch 200. By connecting the pull rod 32 to the hook 201 of the pluggable switch 200, a force opposite to the removal direction is applied to the handle 11 to remove the switch 200.

[0098] The above is an exemplary description of the arrangement of the connecting mechanism 3 in the bracket 1 . The following is an exemplary description of the arrangement of the supporting mechanism 2 in the bracket 1 .

[0099] In some examples, such as the attached Figure 1 , Attachment Figure 3As shown, the support mechanism 2 includes: a support shaft 21 and a plurality of connecting rods 22. The support shaft 21 is rotatably connected between the two support plates 12. The plurality of connecting rods 22 are spaced apart along the thickness direction of the support plates 12. One end of the connecting rod 22 is connected to the side of the support shaft 21 facing the assembly 300 of the plug-in switch 200, and the other end of the connecting rod 22 is used to connect to the assembly 300 of the plug-in switch 200.

[0100] By fixing the connecting rod 22 to the support shaft 21, the rotation centerline of the support shaft 21 and the fixing point of the connecting rod 22 and the assembly 300 are on the same horizontal plane. In this way, when the plug-in switch 200 is inserted or removed, the user applies force to the handle 11 of the bracket 1 to rotate it relative to the support shaft 21. As a result, the bracket 1 rotates relative to the assembly 300 of the plug-in switch 200, thereby applying force to the plug-in switch 200 to insert or remove it from the assembly 300.

[0101] Regarding the connection between the connecting rod 22 and the assembly 300 of the plug-in switch 200, an exemplary embodiment can be as shown in the attached figure. Figure 10 As shown, the connecting rod 22 includes a large diameter cylindrical section 221 and a small diameter cylindrical section 222 connected to each other. A concave strip groove is provided on the outer wall of the small diameter cylindrical section 222 at one end close to the large diameter cylindrical section 221. The strip grooves are set to two symmetrical ones to form a strip column section 223.

[0102] Combine Figure 11 and Figure 12 As shown, the end of the assembly 300 has a mounting hole 301, and the mounting hole 301 includes a circular hole segment 3011 and a strip hole segment 3012 that are connected. The radial dimension of the circular hole segment 3011 is larger to allow the small-diameter cylindrical segment 222 of the connecting support rod 22 to pass through it, and the radial dimension of the strip hole segment 3012 is smaller to prevent the small-diameter cylindrical segment 222 of the connecting support rod 22 from entering therein and allow the strip column segment 223 to enter therein, so that the strip column segment 223 is fitted and clamped in the strip hole segment 3012, thereby realizing a fixed connection between the connecting support rod 22 and the assembly 300.

[0103] When the mounting device 100 needs to be connected to the assembly 300, the small-diameter cylindrical section 222 and the strip-shaped column section 223 are sequentially inserted into the circular hole section 3011, and the support mechanism 2 is then moved so that the strip-shaped column section 223 enters the strip-shaped hole section 3012 for locking. When the mounting device 100 needs to be removed from the assembly 300, the support mechanism 2 is moved so that the strip-shaped column section 223 moves from the strip-shaped hole section 3012 to the circular hole section 3011, and the connecting rod 22 can be pulled out of the mounting hole 301.

[0104] In an embodiment of the present invention, while ensuring that the installation device 100 does not interfere with the switch 200, the axial length of the connecting rod 22 can be shortened as much as possible, so that the rotation center of the installation device 100 is closer to the connection point between the installation device 100 and the assembly 300, thereby avoiding the overall shaking of the installation device 100 during the installation process.

[0105] In some examples, such as the attached Figure 13 As shown, the side of the support shaft 21 facing away from the assembly body 300 of the plug-in switch 200 has a first stop 23, and the support plate 12 has a second stop 14; the first stop 23 and the second stop 14 cooperate to stop to limit the rotation angle of the bracket 1.

[0106] In order to improve the stopping effect, the first stop block 23 and the second stop block 14 can be symmetrically set to two. For example, the two first stops 23 are respectively protruded and arranged on the two ends of the support shaft 21 close to the support plate 12, and the second stops 14 are respectively protruded and arranged on the inner side walls of the two support plates 12.

[0107] The second stopper 14 may be located on a side of the first stopper 23 that faces away from the connecting mechanism 3 ( Figure 13 ), to limit the rotation angle of the bracket 1 along the first direction, that is, when the plug-in switch 200 is inserted, the rotation angle of the bracket 1 is limited to prevent the plug-in switch 200 from being excessively inserted and caused by wear.

[0108] The second stopper 14 may also be located on the side of the first stopper 23 facing the connecting mechanism 3 (see Figure 13 ) to limit the rotation angle of the bracket 1 along the second direction, that is, when the plug-in switch 200 is unplugged, the rotation angle of the bracket 1 is limited to prevent the plug-in switch 200 from colliding with the mounting device 100 during the unplugging process and causing damage.

[0109] One of the first stopper 23 and the second stopper 14 is in the form of a boss (eg, a cylinder), and the other provides a stop groove adapted to stop the boss. The boss is accommodated in the stop groove to achieve stopping. For example, Figure 10 and Figure 13 In both examples, a side of the first stopper 23 facing the second stopper 14 has a stop groove, and the second stopper 14 is in the form of a convex column.

[0110] Among them, in order to ensure that the first stop block 23 is stably installed on the support shaft 21, the first stop block 23 can be designed to include a connecting plate and stops located at both ends of the connecting plate. The stop blocks are protrudingly arranged on the side of the connecting plate away from the support shaft 21 to smoothly stop the second stop block 14.

[0111] Based on the above, it can be known that the support shaft 21 can rotate relative to the bracket 1. When the support shaft 21 rotates, the first stop block 23 also rotates accordingly. When the first stop block 23 rotates to gradually approach the pressure block 31, the width of the installation device is significantly reduced. At this time, it can be considered that the first stop block 23 is in a retracted state.

[0112] As attached Figure 8 and attached Figure 9 As shown, the surface of the pressure block 31 facing the plug-in switch 200 also has multiple locking structures 33. The multiple locking structures 33 correspond one-to-one to the multiple connecting rods 22. The locking structures 33 are used to lock the connecting rods 22 in the stored state.

[0113] The connecting rod 22 in the stored state is locked by a locking mechanism provided on the pressing block 31 to ensure that the connecting rod 22 is stably placed in the stored state.

[0114] For example, the locking structure 33 may be in the form of a locking block, a strap, a buckle, etc. Figure 9 The locking structure 33 is illustrated as an elastic locking block 331 , which has a locking groove 332 and an opening 333 communicating with the locking groove 332 . The opening 333 allows the connecting rod 22 to enter and exit the locking groove 332 . The locking groove 332 is used to lock the connecting rod 22 .

[0115] Based on its elastic characteristics, the elastic locking block 331 allows the connecting rod 22 to freely enter and exit the locking groove 332, and stably locks the connecting rod 22 based on the locking groove 332. The above-mentioned design of the locking structure 33 can provide a stronger locking force for the connecting rod 22, and is easy to operate, and the user can operate it with one hand.

[0116] In summary, the mounting device 100 provided in this embodiment of the present invention, by providing pull rods 32 at different positions on the bracket 1, is adapted to accommodate various types of plug-in switches 200. Thus, a single mounting device 100 can be used to assemble various types of plug-in switches 200, providing high versatility and cost savings. Due to the structure and arrangement of the various components of the mounting device 100, the mounting device 100 has the advantages of a small number of parts, a simple structure, easy processing and fabrication, high reliability, a small footprint, and easy storage.

[0117] The above description is only for the purpose of facilitating the understanding of the technical solution of the present invention by those skilled in the art and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included in the scope of protection of the present invention.
