Description

Technical Field

[0001] The present application relates to the field of switch cabinet installation equipment, and in particular to a switch cabinet installation frame. Background Art

[0002] Switchgear is a type of electrical control equipment. Based on the cabinet structure, it can be divided into open-type switchgear, fixed metal-enclosed switchgear, and armored removable metal-enclosed switchgear. Based on the voltage level, it can be further divided into high-voltage switchgear, medium-voltage switchgear, and low-voltage switchgear. It is primarily used in various applications, including power plants, substations, petrochemicals, metallurgy and steel rolling, light industry and textiles, factories and mines, residential areas, and high-rise buildings.

[0003] Switchgear uses interconnected horizontal and vertical bars to form a mounting frame for mounting electronic components within the switchgear. However, in conventional switchgear, the horizontal and vertical bars are primarily connected using bolts, making it difficult to adjust the distance between the two bars to accommodate electronic components of different sizes. Utility Model Content

[0004] In order to improve the problem in the prior art that the horizontal bars and vertical bars on the mounting frame inside the switch cabinet are fixed by bolts, resulting in the operation being very troublesome and complicated when the distance between two adjacent horizontal bars needs to be adjusted, the present application provides a switch cabinet mounting frame adopting the following technical solution:

[0005] 7. The swiftly and minutely adjusting device for a wood-planer working table as claimed in claim 1, wherein said linking rod and said adjusting base are pivotally connected to each other with a bolt, and said bolt has a round shank to contact with said linking rod. said linking rod has a round shank to contact with said linking rod.

[0006] By adopting the above technical solution, when it is necessary to change the distance between two side-by-side transverse groove rods or the position of the transverse groove rod on the vertical groove rod, the fixing structure between the locating pin and the vertical groove plate can be released so that the locating pin can slide freely inside the transverse groove rod to facilitate the adjustment of the position of the transverse groove rod, thereby improving the installation structure of the electronic components on the switch cabinet and the simplicity of the installation position adjustment operation, and at the same time will not weaken the stability of the connection structure between the transverse groove rod and the vertical groove rod. In addition, the purpose of designing the length of the connecting block to be greater than the width of the vertical wing plate is to enable the connecting block and the connecting rod to be squeezed when the transverse groove rod and the vertical groove rod are connected, thereby improving the stability of the connection structure.

[0007] Optionally, a sliding hole is formed through one end of the connecting block near the vertical slot rod, and the positioning pin is slidably inserted into the sliding hole. A stepped groove coaxial with the sliding hole is formed at the sliding hole position on the side of the connecting block away from the vertical wing plate. The elastic driving component includes a mounting ring threadedly connected to the end position of the stepped groove, the mounting ring is slidably connected to the positioning pin, and a driving spring is connected to one end of the mounting ring near the bottom of the stepped groove, and the end of the driving spring is fixedly connected to a connecting ring fixedly sleeved with the positioning pin, and the driving spring is always in a compressed state.

[0008] By adopting the above technical solution, it can be achieved that when the connecting block is moved to the position of the sliding hole on the vertical slot rod, the driving spring on the connecting block can drive the connecting ring and the positioning pin fixedly sleeved with the connecting ring to enter the positioning hole. The structure is simple and easy to operate, which reduces the cost and difficulty of manufacturing the mounting frame. The mounting ring is threadedly connected to the notch position of the stepped groove on the connecting block to compensate for the elasticity of the driving spring, preventing the driving spring from becoming insufficiently elastic due to frequent use, which ultimately makes the connection structure between the connecting block and the vertical slot plate unstable.

[0009] Optionally, a pull tab is fixedly connected to one end of the fixing pin away from the stepped groove, and a dimension of the pull tab along the cross section is larger than the diameter of the sliding hole.

[0010] By adopting the above technical solution, it can be made more convenient to move the position of the horizontal groove rod on the vertical groove rod, and it can avoid the situation where the staff's hands are rubbed when pressing the positioning pin by hand because the positioning pin abuts against the positioning hole, causing injuries to the staff.

[0011] Optionally, a fixing plate with the same width as the transverse groove plate is integrally provided at both ends of the transverse groove rod, the thickness of the fixing plate is greater than the thickness of the transverse groove plate, and a fixing hole coaxial with the positioning hole is opened through the fixing plate, and the positioning pin is slidably passed through the fixing hole.

[0012] By adopting the above technical solution, the stability of the connection structure formed by the positioning pins between the transverse groove rod and the vertical groove rod can be enhanced, thereby preventing the two ends of the transverse groove rod from being subjected to excessive radial force, which may cause them to bend or break.

[0013] Optionally, the limiting structure includes a plurality of limiting holes that are opened side by side on the two transverse wing plates and a plurality of limiting components that are symmetrically arranged on both sides of the connecting block near the two transverse wing plates, and the limiting component includes a limiting spring embedded in the connecting block, and a hemispherical limiting pin is connected to the end of the limiting spring, and the limiting pin extends out of the connecting block, and one side of the hemispherical structure of the limiting pin is movably fitted in the limiting hole, and the limiting spring is always in a compressed state.

[0014] By adopting the above technical solution, the limit spring drives a part of the upper end of the limit pin into the limit hole, and forms an elastic clamping structure at the position of the limit hole. The limit components located on both sides of the connecting block work together to allow the connecting block to slide on the cross groove rod. At the same time, without affecting the sliding of the connecting block, since the connecting block is not subjected to lateral force, it will not easily fall off the cross groove rod along the width direction of the cross groove plate.

[0015] Optionally, there are at least four limiting components located on the same side of the connecting block, and they are evenly arranged on the side of the connecting block, and the four limiting components are movably matched with the four adjacent limiting holes on the transverse wing plate.

[0016] By adopting the above technical solution, the stability of the limiting structure between the connecting block and the transverse groove rod is enhanced, and the possibility of the connecting block falling out of the transverse groove rod in the transverse direction due to elastic abnormality of the limiting spring is reduced.

[0017] Optionally, triangular support blocks are fixedly provided at both ends of the transverse groove plate, and a slide groove is provided on the side of the support block close to the vertical wing plate along the extension direction of the vertical wing plate, and two mounting holes are symmetrically provided on the two opposite inner walls of the slide groove, and a movable pin with an arc structure on one side is slidably provided in each of the two mounting holes, and a clamping spring with two ends fixedly connected to the movable pin and the bottom of the slide groove respectively is provided in the mounting hole, and the clamping spring is always in a compressed state, and the two movable pins and several of the positioning holes are in the same vertical plane.

[0018] By adopting the above technical solution, when the position of the transverse groove rod is fixed on the vertical groove rod, the two clamping springs on the support block respectively drive the ends of the two movable pins into the mounting holes, thereby providing auxiliary support for the transverse groove rod. At the same time, it will not affect the sliding of the transverse groove rod on the vertical groove rod, and also provides a transverse limit for the transverse groove rod to prevent it from separating from the vertical groove rod when moving.

[0019] Optionally, a plurality of waist-shaped holes are formed at equal intervals along the length direction of the transverse groove plate, and the electronic components are installed in the waist-shaped holes.

[0020] By adopting the above technical solution, the position of the electronic components on the transverse groove rods can be adjusted within a certain range, making it more convenient to connect the electronic components inside the switch cabinet to the circuit.

[0021] In summary, this application includes at least one of the following beneficial technical effects:

[0022] 1. This invention provides a slidable connecting block on the transverse slot rod, which is connected to the vertical slot rod. This allows the transverse slot to move along the vertical slot rod in the direction of its extension, facilitating the installation of electronic components and the connection of different electronic components within the switch cabinet.

[0023] 2. This application provides a limiting structure and a support block on the connecting block to prevent the horizontal groove rod from separating from the vertical groove rod during the sliding process, making the connection structure between the horizontal groove rod and the vertical groove rod more stable;

[0024] 3.

[0032] The following is combined with Figure 1-6 This application is described in further detail.

[0033] An embodiment of the present application discloses a switch cabinet mounting bracket.

[0034] Reference Figure 1 A switch cabinet mounting frame includes a vertical slotted rod 1 fixedly mounted on the inner side wall of the switch cabinet along a vertical direction, and a plurality of transverse slotted rods 2 connected between adjacent vertical slotted rods 1 on the same vertical plane, wherein the plurality of transverse slotted rods 2 are arranged side by side. Electronic components for connecting circuits are mounted on a single transverse slotted rod 2 or on multiple transverse slotted rods 2. Specifically, a plurality of waist-shaped holes 211 are formed through the transverse slotted rod 2 at equal intervals along its extension direction, and the electronic components are slidably mounted within the waist-shaped holes 211. Due to the different shapes of the electronic components, they are not shown in the drawings of this application.

[0035] Specifically, the transverse groove bar 2 comprises an integrally connected transverse groove plate 21 and two transverse wing plates 22. The two transverse wing plates 22 are symmetrically positioned at opposite ends of the same side of the transverse groove plate 21 and are perpendicular to each other. The vertical groove bar 1 has the same structure as the transverse groove bar 2, comprising a vertical groove plate 11 and two vertical wing plates 12. The ends of the transverse groove bar 2 slide within the two vertical groove bars 1, with the side of the transverse groove plate 21 facing away from the transverse wing plate 22 abutting against the side of the vertical wing plate 12 closest to the other vertical wing plate 12.

[0036] Reference Figure 2 and Figure 3The two vertical wing plates 12 are provided with a plurality of positioning holes 121 at equal intervals along the length direction. Two connecting blocks 3 are slidably provided along the length direction of the transverse groove rod 2. The ends of the two connecting blocks 3, which are separated from each other, are provided with positioning pins 4 that slide in conjunction with the positioning holes 121. The positioning pins 4 are connected to the elastic drive assembly 5, which is provided on the connecting blocks 3. When the connecting blocks 3 slide to the ends of the transverse groove rod 2, the positioning pins 4 slide into the positioning holes 121 under the action of the elastic drive assembly 5. The two connecting blocks 3 at both ends of the transverse groove rod 2 work together to support the transverse groove rod 2 and secure the transverse groove rod 2 to the vertical groove rod 1.

[0037] It should be emphasized here that the length of the connecting block 3 along the extension direction of the horizontal groove rod 2 should be greater than the width of the vertical wing plate 12, and without affecting the installation of electronic components on the horizontal groove rod 2, the length of the connecting block 3 should be at least twice the width of the vertical wing plate 12.

[0038] Preferably, when the positioning pin 4 on the connecting block 3 is inserted into the positioning hole 121 on the vertical wing plate 12, the end of the connecting block 3 is in close contact with the side of the vertical slot plate 11 close to the vertical wing plate 12, so that the horizontal slot rod 2 can remain horizontal. At the same time, this design structure can also prevent the horizontal slot rod 2 from suddenly sliding down when the positioning pin 4 breaks.

[0039] Reference Figure 3 At both ends of the transverse groove bar 2, fixed plates 6 are integrally provided, one side of which is flush with the transverse groove plate 21. Fixed plates 6 are provided with fixing holes 61 that slideably engage with the locating pins 4. When the transverse groove bar 2 is fixed in position, the locating pins 4 pass through the locating holes 121 and extend into the fixing holes 61. The thickness of the fixed plates 6 is greater than that of the transverse groove plate 21, and their length along the extension direction of the transverse groove bar 2 is equal to the width of the vertical wing plates 12.

[0040] Reference Figure 3 and Figure 4 The elastic drive assembly 5 includes a mounting ring 51 and a drive spring 52 fixedly connected to one end of the mounting ring 51 and coaxial with the mounting ring 51. A sliding hole 31 is provided on the connecting block 3 near the vertical slot rod 1, and the positioning pin 4 is slidably inserted into the sliding hole 31. A stepped groove 32 coaxial with the sliding hole 31 is provided on the side of the connecting block 3 away from the vertical wing plate 12, and the mounting ring 51 and the drive spring 52 are arranged in the stepped groove 32. A connecting ring 53 is fixedly connected to the end of the drive spring 52 away from the mounting ring 51. The connecting ring 53 is slidably arranged in the stepped groove 32 and fixedly sleeved on the positioning pin 4. The drive spring 52 is always in a compressed state, that is, when the positioning pin 4 is located in the positioning hole 121, the connecting ring 53 is in close contact with the bottom of the stepped groove 32.

[0041] Reference Figure 4Furthermore, the mounting ring 51 and the stepped groove 32 are threadedly connected so that when the elastic force of the driving spring 52 is insufficient, the user can increase the elastic force of the driving spring 52 by rotating the mounting ring 51.

[0042] Reference Figure 4 Furthermore, a pull tab 41 is integrally connected to the end of the positioning pin 4 away from the positioning hole 121, so that the user can more conveniently move the positioning pin 4 and avoid scratching the back of the user's hand by pressing the positioning pin 4 from the front. The cross-sectional dimension of the pull tab 41 is larger than the dimension of the sliding hole 31 to prevent the pull tab 41 from entering the sliding hole 31, resulting in an inability to smoothly pull the positioning pin 4.

[0043] Reference Figure 3 and Figure 4 A limiting structure 7 is provided between the connecting block 3 and the transverse groove rod 2 to prevent the connecting block 3 from moving along the width of the transverse groove rod 2. This structure comprises a plurality of limiting holes 71 extending side by side through the two transverse wing plates 22, and a plurality of limiting assemblies 72 symmetrically disposed on opposite sides of the connecting block 3 near the transverse wing plates 22. The limiting assemblies 72 specifically comprise a limiting spring 721, one end of which is embedded within the connecting block 3, and a limiting pin 722 fixedly connected to the other end of the limiting spring 721. The limiting pin 722 has a hemispherical structure at the end away from the limiting spring 721. The hemispherical end of the limiting pin 722 extends out of the connecting block 3 and engages with the limiting hole 71. During this process, the limiting spring 721 remains in a compressed state.

[0044] It should be noted that in this application, when the connecting block 3 slides on the transverse groove rod 2, the staff can manually or use a device to drive the connecting block 3 so that the limiting pin 722 enters the interior of the connecting block 3, without affecting the sliding of the connecting block 3. The main function of the limiting structure 7 is only to limit the connecting block 3 in the lateral direction to prevent it from falling out of the transverse groove rod 2.

[0045] Reference Figure 4 Preferably, there are four sets of limit assemblies 72 in the present application, and they are symmetrically installed on both sides of the connecting block 3. In the design structure of the present application, too many limit assemblies 72 will hinder the movement of the connecting block 3, while too few limit assemblies 72 cannot completely limit the lateral movement of the connecting block 3.

[0046] Furthermore, the distance between the two limiting components 72 located on the same side of the connecting block 3 is equal to the distance between the two limiting holes 71 on the cross wing plate 22, so that the four groups of limiting components 72 can all be engaged with the cross groove rod 2, thereby improving the stability of the engaging structure.

[0047] Reference Figure 3 and Figure 5A right-angled triangular support block 8 is fixedly mounted below each end of the transverse slot plate 21. One right-angled surface of the support block 8 is connected to the lower end of the transverse wing plate 22. The other right-angled surface of the support block 8 is adjacent to the vertical wing plate 12, and a sliding groove 81 is defined vertically through this right-angled surface for sliding engagement with the vertical wing plate 12. When the transverse slot rod 2 is fixedly mounted between the two vertical slot rods, the two vertical wing plates 12 at each end of the transverse slot rod 2 are located within the two sliding grooves 81, respectively.

[0048] Reference Figure 5 and Figure 6 Furthermore, two mounting holes 82 are symmetrically defined on opposing sidewalls within the slideway 81. A movable pin 83 with an arc-shaped structure on one side is slidably disposed within each mounting hole 82. A clamping spring 84 is fixedly connected between each movable pin 83 and the bottom of the mounting hole 82. The two clamping springs 84 respectively drive one end of the curved structure of the movable pins 83 to engage within the positioning hole 121. The ends of the two movable pins 83 abut against each other, providing auxiliary support for the cross-groove rod 2 and enhancing the stability of the mounting frame structure.

[0049] The implementation principle of a switch cabinet mounting bracket in the embodiment of the present application is as follows:

[0050] First, the horizontal groove bar 2 is slidably connected to the vertical groove bar. The support block 8 at the bottom of the horizontal groove bar 2 is slidably connected to the vertical wing plate 12, preventing the horizontal groove bar 2 from sliding laterally while providing temporary support for the vertical sliding of the horizontal groove bar 2. The two connecting blocks 3 are then manually slid to the ends of the horizontal groove bar 2, and the locating pins 4 are driven by the elastic drive assembly to spring into the locating holes 121 and the fixing holes 61 on the fixing plate 6, thereby securing the horizontal groove plate 21.

[0051] When moving the transverse groove rod 2, one only needs to pull the pull tab 41 to disengage the positioning pin 4 from the positioning hole 121 and the fixing hole 61 to move the connecting block 3. The connecting block 3 then slides on the transverse groove rod 2 under the action of the limiting assembly 72, and the transverse groove rod 2 can now freely adjust its position on the vertical groove rod 1.

[0052] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
