[0034] In existing electrical equipment, installing the cabinet unit module into the cabinet mostly requires installation auxiliary devices, such as using sheet metal to make a ramp bracket to place the unit module on the bracket, and then guiding the unit module to be installed into the cabinet or taken out of the cabinet by manual pushing. In this structure, the bracket is in a non-horizontal state, and manual pushing is laborious, and the bracket can be tilted within a certain range, resulting in a limited height range for the installation of the unit module; another example is using a hydraulic device plus a bracket to form a trolley structure to place the unit module on the trolley, and adjusting the height for installation by the hydraulic device, which is suitable for a larger height installation range, but the cost is high and the operating space is not flexible; another example is directly using a crane or forklift for installation, but it requires a larger operating space, and it cannot be used in many occasions (cabins, offshore platforms, outdoor containers, etc.), and the cost is higher. Therefore, there is an urgent need for a simple structure, low cost, and practical unit module installation auxiliary device to solve the above problems.

[0035] In view of this, the utility model provides a mounting bracket. Figures 1 to 3 The embodiment of the mounting bracket provided by the present invention will be described below in conjunction with specific drawings.

[0036] See also Figures 1 to 3 The mounting bracket 100 includes a support frame 1, a movable frame 2 and a mounting plate 4. The movable frame 2 can be movably mounted on the support frame 1 along the up and down directions, and a locking structure 3 is arranged between the movable frame 2 and the support frame 1. The locking structure 3 is used to position the movable frame 2 at different heights. One end of the mounting plate 4 is mounted on the movable frame 2, and the other end is provided with a lap portion 41. The lap portion 41 is used to overlap the cabinet so that the mounting plate 4 is spanned between the cabinet and the movable frame 2. At least one rolling member 42 is arranged on the mounting plate 4, and the rotation axis of the rolling member 42 is arranged at an angle to the extension direction of the mounting plate 4.

[0037] In the technical solution of the present invention, the mounting plate 4 is mainly used to carry the unit module outside the cabinet, and guide the unit module to move from the mounting plate 4 to the cabinet to complete the installation of the unit module, or carry the unit module unloaded from the cabinet to facilitate the installation and removal of the unit module. To meet the above functions, one end of the mounting plate 4 is supported by the support frame 1 and the movable frame 2, and the other end of the mounting plate 4 is overlapped to the cabinet by the overlap portion 41 for support. In this way, while ensuring the stability of the mounting plate 4, the weight of the unit module carried by the mounting plate 4 is dispersed to the cabinet, so as to simplify the support structure composed of the support frame 1 and the movable frame 2 and reduce its structural strength cost. On this basis, in order to meet different installation heights, the movable frame 2 can be movably installed on the support frame 1 up and down, and a locking structure 3 is provided between the movable frame 2 and the support frame 1. The locking structure 3 is used to position and fix the movable frame 2 after the height adjustment is completed on the support frame 1, so as to fix the height of the mounting plate 4 at one end of the movable frame 2. When the height of one end of the mounting plate 4 is adjusted to the height of the other end of the mounting plate 4, the two ends of the mounting plate 4 are made flush, which can avoid the problem of difficulty in pushing the unit module due to the tilt of the mounting plate 4. Furthermore, at least one rolling member 42 is also provided on the mounting plate 4, and the rotating axis of the rolling member 42 is arranged at an angle to the extension direction of the mounting plate 4, so that when the unit module is taken out of the cabinet or loaded into the cabinet, the friction between the unit module and the mounting plate 4 is reduced. On the one hand, it is convenient to push and more labor-saving. On the other hand, the wear between the unit module and the mounting plate 4 is reduced, thereby extending the service life. It should be noted that the extension direction of the mounting plate 4 is the direction extending from one end of the mounting plate 4 mounted on the movable frame 2 to the other end of the mounting plate 4 overlapped on the cabinet, or from the other end of the mounting plate 4 overlapped on the cabinet to one end of the mounting plate 4 mounted on the movable frame 2. Preferably, the angle between the rotation axis of the rolling element 42 and the extension direction of the mounting plate 4 is 90°, and the unit module can be quickly sent into the cabinet or taken out of the cabinet along the extension direction of the mounting plate 4. And based on the fact that one end of the mounting plate 4 is overlapped on the cabinet, the supporting load of the supporting structure composed of the movable frame 2 and the supporting frame 1 is reduced, and the structural strength of the locking structure 3 can also be set lower to further reduce the cost, and can meet the requirement of stable support. In summary, the main body of the mounting bracket 100 is composed of a supporting frame 1 placed on a supporting surface, a movable frame 2 movably arranged on the supporting frame 1 up and down, and a mounting plate 4 straddling the cabinet and the movable frame 2. The overall structure is simple, the cost is low, the required operating space is small, and the operation is convenient, so that it is highly practical.

[0038] Specifically, the mounting plate 4 is rotatably mounted on the movable frame 2 along a horizontal axis, so that the mounting plate 4 has a storage state close to the movable frame 2 and an overlap state extending horizontally in the rotation stroke. In order to facilitate the storage and overlap support of the mounting plate 4, the mounting plate 4 is configured to rotate along a horizontal axis extending in a horizontal direction, so that the weight of the mounting plate 4 can be used when storing, which is more labor-saving, and the storable design can save the space occupied by the mounting bracket 100. When unfolded for overlap, its overlap portion 41 is supported by the cabinet, which can limit the rotation of the mounting plate 4 and provide greater stability. Specifically, the support structure composed of the support frame 1 and the movable frame 2 is a vertically extending structure, and the mounting plate 4 is a horizontally extending structure, and one end of the mounting plate 4 is used to overlap the cabinet. When the mounting bracket 100 is removed from the cabinet, the structural mounting bracket 100 cannot support itself, and when it is laid on the ground or placed against a wall, because the mounting plate 4 and the movable frame 2 are perpendicular or nearly perpendicular to each other, the mounting bracket 100 occupies a large space and is not convenient for storage and placement. Therefore, in the present application, the mounting plate 4 is rotatably installed on the movable frame 2 so that it has a stored state and a overlapped state. On the basis of satisfying that one end of the mounting plate 4 is overlapped on the cabinet and the other end is supported on the movable frame 2 to meet the bearing and movable guiding of the unit module, the storage requirements of the mounting bracket 100 are met, thereby reducing the space occupied by the mounting bracket 100.

[0039] Furthermore, a stopper 45 is provided on the mounting plate 4, and a stopper 23 is provided on the movable frame 2. The stopper 23 abuts against the stopper 45 to limit the rotation angle A of the mounting plate 4 relative to the movable frame 2, and A≤90°. The stopper 45 abuts against the stopper 23 to limit the maximum rotation angle of the mounting plate 4 relative to the movable frame 2, and the structure is simple and reliable. However, the movable frame 2 is a load-bearing component. In some usage scenarios, the stopper 45 and the stopper 23 abut against each other with great force, making both of them easy to be damaged. Therefore, in the present application, the stopper 23 is set as a detachable structure to facilitate replacement and extend the service life. The rotation angle of the mounting plate 4 is not limited as long as it can meet the above-mentioned load-bearing and storage requirements. In this embodiment, the maximum rotation angle is limited to 90 degrees, that is, the mounting plate 4 is perpendicular to the movable frame 2. On the one hand, the stability of the mounting bracket 100 is improved, and on the other hand, it prevents the end of the mounting plate 4 overlapping the cabinet from being higher than the end of the mounting plate 4 connected to the movable frame 2, thereby preventing the unit module from slipping off the mounting bracket 100 along the inclined mounting plate 4.

[0040] In addition, a locking structure 5 is provided between the mounting plate 4 and the movable frame 2, and the locking structure 5 is used to lock the angle between the mounting plate 4 and the movable frame 2. Based on the fact that the mounting plate 4 can be rotatably arranged for easy storage, in order to ensure the stability of the mounting plate 4 during use, the present application also provides a locking structure 5 between the mounting plate 4 and the movable frame 2, so as to lock the mounting plate 4 and the movable frame 2 after the angle between the mounting plate 4 and the movable frame 2 is adjusted, thereby limiting the relative rotation of the two. It can be understood that the locking structure 5 and the above-mentioned stop portion 45 can be set independently without any specific influence on each other, and both have a certain function of improving the stability of the mounting plate 4. In the present application, the locking structure 5 and the stop portion 45 are provided at the same time, so that when using the mounting bracket 100, the mounting plate 4 can be first rotated until the stop portion 45 and the stop member 23 abut against each other to achieve limiting, that is, the angle between the mounting plate 4 and the movable frame 2 is almost vertical, and then the movable frame 2 and the mounting plate 4 are locked by the locking structure 5 to fix the angle, and then the height of the movable frame 2 can be adjusted to achieve the horizontality of the mounting plate 4. The overall operation is simple, that is, the stop portion 45 is mainly used to determine the vertical relationship between the mounting plate 4 and the movable frame 2, and the locking structure 5 is used to lock the mounting plate 4 and the movable frame 2 to improve their stability, so that the horizontal state and stability of the mounting plate 4 during use can be guaranteed to meet the use requirements.

[0041] Specifically, the mounting plate 4 is provided with a bolted connector 44. In one embodiment, the locking structure 5 includes a locking member 51 that passes through a connection hole on the bolted connector 44 and is threadedly connected to the movable frame 2 to fix the angle between the mounting plate 4 and the movable frame 2. The specific setting methods of the locking structure 5 can be various, including but not limited to pin-connection limiting, clamping limiting, and clamping limiting, etc., which can achieve relative locking of the mounting plate 4 and the movable frame 2 and limit the rotation of the mounting plate 4. In this embodiment, the locking structure 5 mainly adopts a threaded connection structure, that is, a threaded connection is performed through the locking member 51, so that when the locking member 51 is threadedly connected to the movable frame 2, the locking portion on the locking member 51 clamps the bolted connector 44 with the movable frame 2 to limit the rotation of the mounting plate 4, thereby achieving the limit locking of the movable frame 2 and the mounting plate 4. The structure is stable and reliable, and meets the use requirements. In another embodiment, the locking structure 5 includes a locking member 51 and a second slider 52. The movable frame 2 is laterally provided with a third slide groove 213 extending in the up-down direction. The second slider 52 is slidably disposed in the third slide groove 213. A limiting portion extending up-down is disposed at the notch of the third slide groove 213 to limit the second slider 52 from escaping from the third slide groove 213. The locking member 51 passes through the connecting hole on the bolt connector 44 and is threadedly connected to the second slider 52. The locking member 51 and the second slider 52 are used to clamp and lock the bolt connector 44 to fix the mounting plate 4 and the mounting plate 4. The angle between the movable frame 2, in this embodiment, on the one hand, through the threaded connection between the locking member 51 and the second slider 52, the locking portion on the locking member 51 and the second slider 52 clamp the locking bolt connection member 44 to limit the rotation of the mounting plate 4, thereby fixing the angle between the mounting plate 4 and the movable frame 2, on the other hand, through the sliding cooperation between the second slider 52 and the third slide groove 213, the height of the mounting plate 4 relative to the movable frame 2 can be flexibly adjusted, thereby achieving fine adjustment of the height of the mounting plate 4, thereby improving the accuracy of the overlap between the mounting plate 4 and the cabinet.

[0042] In addition, the mounting plate 4 is arranged to rotate around the axial direction of the locking member 51. That is, the rotation axis direction of the mounting plate 4 is the same as the axial direction of the locking member 51. The rotation axis of the mounting plate 4 and the movable frame 2 does not need to be limited, and it is sufficient to satisfy the rotation of the mounting plate 4 relative to the movable frame 2. In this embodiment, based on the locking member 51 being screwed to the movable frame 2 to clamp and lock the mounting plate 4, the axial direction of the locking member 51 is used as the rotation axis direction of the mounting plate 4 to be rotated and installed on the movable frame 2. On the one hand, the locking member 51 realizes the two functions of locking and supporting rotation, and there is no need to set the connection hole on the bolted connector 44 on the thickness side of the bolted connector 44, which reduces the thickness of the bolted connector 44 and has low cost. On the other hand, when it is necessary to adjust the angle between the mounting plate 4 and the movable frame 2, the locking member 51 does not need to be removed, which facilitates locking and angle adjustment operations. It should be noted that in this embodiment, the side direction of the movable frame 2 is the opposite side or the opposite side of the two frame bodies 21 of the movable frame 2.

[0043] Furthermore, the movable frame 2 is laterally provided with a first slide groove 211 extending in the up-down direction, and a limit portion 212 extending up-down is provided at the notch of the first slide groove 211; the locking structure 3 includes a first slider 32 that can slide along the first slide groove 211 and a locking member 31 that passes through the support frame 1 and is threadedly connected to the first slider 32, and the locking member 31 and the first slider 32 are used to clamp the relative movement between the locking limit portion 212 and the support frame 1. Similar to the above-mentioned locking structure 5, the locking structure 3 can also be set in a variety of ways, which can limit the relative movement of the movable frame 2 relative to the support frame 1, and can be a pin limit, a clamp limit, and a clamp limit, etc., which are not limited here, and are mainly based on actual needs. In this embodiment, the locking structure 3 is set to be a locking member 31 and a first slider 32 threadedly connected, so that the locking member 311 and the first slider 32 clamp the relative movement between the locking limit portion 212 and the support frame 1. Specifically, there is a relative movable setting between the movable frame 2 and the support frame 1, which is not convenient for setting the connection point of the locking member 31 of the threaded connection structure. Therefore, in this embodiment, by setting a connection point on the first slider 32, that is, the locking member 31 is threadedly connected with the first slider 32, so that the locking portion 311 on the locking member 31 and the first slider 32 clamp the limiting portion 212 at the notch of the first slide groove 211 on the movable frame 2 and the support frame 1 to achieve the locking function. At this time, the first slider 32 can slide along the first slide groove 211, that is, when the frame 21 moves up and down relative to the support frame 1, the position of the locking member 31 and the first slider 32 can be left unchanged, so that it is not necessary to set multiple threaded connection points to cope with different heights of the frame 21. The structural design is simple, and the locking of the frame 21 at different heights can be achieved without adjusting the position of the locking member 31. The operation is simple and practical. Preferably, in this embodiment, the side of the movable frame 2 is the side of the two frames 21 of the movable frame 2 that are opposite to each other.

[0044] In addition, the support frame 1 includes two brackets 11 arranged opposite to each other, and a second slide groove 111 extending upward and downward is provided on one side opposite to the two brackets 11; the movable frame 2 includes two frame bodies 21 extending upward and downward and a reinforcing beam 22 connecting the two frame bodies 21, and the two frame bodies 21 are respectively placed in the two second slide grooves 111. The structure of the support frame 1 can be various, specifically in the form of a support seat, etc., as long as it can support the movable frame 2, which is not limited here. In this embodiment, the support frame 1 is set as two spaced brackets 11, and a second slide groove 111 is provided on one side opposite to the two brackets 11. At the same time, the movable frame 2 is set as two spaced brackets 21 and a reinforcing beam 22 connecting the two frame bodies 21, and the frame body 21 is extended into the second slide groove 111 to achieve limited installation, so as to meet the upward and downward movement of the movable frame 2 relative to the support frame 1, and has strong stability. At the same time, the structure is simple and low in cost, and the structural strength of the movable frame 2 is also guaranteed.

[0045] In addition, the rolling element 42 includes a plurality of rolling elements 42, and the plurality of rolling elements 42 are arranged at intervals along the extension direction of the mounting plate 4, and / or the plurality of rolling elements 42 are arranged at intervals along the direction of the rotation axis thereof. The specific arrangement of the rolling element 42 is not limited, and it is sufficient to satisfy the function of reducing friction by rolling. In this embodiment, the plurality of rolling elements 42 are arranged at intervals along the extension direction of the mounting plate 4 to form a rolling element assembly, and two rolling element assemblies are arranged at intervals along the direction of the rotation axis of the rolling element 42, so that the support for the unit module can be ensured while shortening the size of the rolling element 42, reducing costs and improving structural stability.

[0046] In addition, a locking structure 411 is provided on the overlapped portion 41, and the locking structure 411 is used to lock the mounting plate 4 and the cabinet. The overlapped portion 41 can achieve the function of bearing support by overlapping the cabinet, but it is obvious that the overlap size is small, and during the movement of the unit module, the overlapped portion 41 may fall off from the cabinet, affecting the stability and safety of the use of the mounting bracket 100. Therefore, in this embodiment, a locking structure 411 is also provided on the overlapped portion 41 to lock the overlapped portion 41 and the cabinet when the overlapped portion 41 is overlapped on the cabinet, so as to prevent the overlapped portion 41 from falling off, thereby improving the stability and safety of the use of the mounting bracket 100.

[0047] In addition, guide portions 43 are convexly provided on both sides of the mounting plate 4, and the guide portions 43 are used to limit and guide the unit module to move along the extension direction of the mounting plate 4. In order to avoid the unit module carried on the mounting plate 4 being offset when being pushed, resulting in the inability to directly transfer into the cabinet and requiring time-consuming and laborious position adjustment, the present embodiment further convexly provides guide portions 43 on both sides of the mounting plate 4 to form a guide groove located between the two guide portions 43, so as to guide the moving direction of the unit module, facilitate the alignment of the unit module with the cabinet, avoid the time-consuming and labor-intensive adjustment of the unit module, and be more practical.

[0048] The utility model also provides a cabinet assembly, which includes a cabinet and a mounting bracket 100. A mounting groove is provided on one side of the cabinet, and the mounting groove is used to install the unit module. The specific structure of the mounting bracket 100 refers to the above embodiment. Since the cabinet assembly adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be repeated here. The mounting bracket 100 is used to carry and guide the unit module to be placed in the mounting groove.

[0049] The above description is only a preferred embodiment of the utility model, and does not limit the patent scope of the utility model. All equivalent structural changes made by using the contents of the utility model specification and drawings under the utility model concept, or directly / indirectly used in other related technical fields are included in the patent protection scope of the utility model.
