TECHNICAL FIELD

[0001] The utility model relates to electrical equipment technical field, concretely is the middle -placed cabinet door check support structure. BACKGROUND

[0002] The middle -placed cabinet (also be called switch cabinet or distribution cabinet) is a kind of equipment for distribution and control in power system. Usually on cabinet door, various instruments, indicating device and operating button are installed, facilitate the monitoring and operating control of the running state of power system. In the cabinet body, terminal and other electrical components are installed, and the instruments and operating switches installed on the instrument door are connected with the electrical components in the cabinet by wire.

[0003] In the opening process of cabinet door, if the opening angle is larger, it is easy to cause cabinet door to open excessively, and the instruments on cabinet door can collide with the instruments of adjacent switch cabinet and cause damage. At the same time, in the closing process of cabinet door, it is necessary to ensure that the cabinet door enters the predetermined position smoothly, to avoid jamming and misaligned door plate. The cabinet door needs to have reliable support and fixation in the closed state, to prevent loosening caused by external impact or vibration, and deformation caused by insufficient support. SUMMARY

[0023] The following will be further described in detail through specific embodiments:

[0024] The marks in the drawings of the specification include: cabinet door 1, first mounting strip 2, roller bracket 3, roller 4, first movable part 5, limiting plate 6, second mounting strip 7, limiting sliding groove 8, second movable part 9, first sleeve 10, transition part 11, second sleeve 12, first nut 13, stepped bolt 14, second nut 15, stepped sleeve 16, and bolt 17.

[0025] Example 1

[0026] The embodiment provides a cabinet door limiting support structure of a middle cabinet, which has the structure as shown in the figure. Figure 1 The cabinet door limiting support structure of the middle cabinet comprises a cabinet door 1, a cabinet body, a cabinet door limiting structure and a cabinet door supporting structure.

[0027] The inner lower part of the cabinet door 1 is provided with a horizontal first mounting strip 2, one mounting hole is arranged at the left end of the first mounting strip 2, and three mounting holes are arranged at the right end of the first mounting strip 2 in a spaced manner. The lower part of the cabinet opening is provided with a second mounting strip 7 in a reverse L-shaped cross section.

[0028] The cabinet door limiting structure comprises a limiting plate 6, a limiting sliding groove 8, a first movable part 5 and a second movable part 9. The limiting sliding groove 8 is arranged on the horizontal surface of the second mounting strip 7, and the limiting sliding groove 8 comprises a strip-shaped sliding groove and a hole with a larger diameter at the end of the sliding groove. The two ends of the limiting plate 6 are provided with holes, one end of the limiting plate 6 is movably connected with the first mounting strip 2 through the first movable part 5 and the right mounting hole of the first mounting strip 2, and the other end of the limiting plate 6 is movably connected with the limiting sliding groove 8 through the second movable part 9.

[0029] The first movable part 5 comprises a first nut 13 and a stepped bolt 14, and the structure is as shown in Figure 2 . The stepped bolt 14 comprises a stud portion with a smaller diameter and a stepped portion with a larger diameter, the diameter of the stud portion is smaller than the diameter of the hole of the limiting plate 6, the diameter of the stepped portion is larger than the diameter of the hole of the limiting plate 6, the stud portion of the stepped bolt 14 passes through the hole of the limiting plate 6, the right mounting hole of the first mounting strip 2 and the first nut 13 in sequence, the first nut 13 and the stepped bolt 14 movably connect the limiting plate 6 with the first mounting strip 2, and the limiting plate 6 can rotate along the axis of the stepped bolt 14 with the change of the opening angle of the cabinet door 1.

[0030] The second movable part 9 comprises a second nut 15, a stepped sleeve 16 and a bolt 17, and the structure is as shown in Figure 4 . The stepped sleeve 16 comprises a first sleeve 10 with a larger diameter at the upper part, a second sleeve 12 with a smaller diameter at the lower part and a trapezoidal transition part 11 at the middle part, as shown in Figure 3 . The bolt 17 passes through the stepped sleeve 16, the hole at the other end of the limiting plate 6 and the second nut 15 in sequence.

[0031] The width of the strip-shaped sliding groove of the limiting sliding groove 8 is greater than the outer diameter of the second sleeve 12 and less than the outer diameter of the first sleeve 10; the diameter of the end opening is greater than the outer diameter of the first sleeve 10. That is, the second movable part 9 has different diameters, the middle part has the smallest diameter, which is the outer diameter of the second sleeve 12, the upper part and the lower part have greater diameters, which are the outer diameter of the first sleeve 10 and the diameter of the nut respectively, both of which are greater than the width of the strip-shaped sliding groove, thus the middle part of the second movable part 9 is clamped in the strip-shaped sliding groove, and the upper part and the lower part of the second movable part 9 are clamped at the upper end and the lower end of the strip-shaped sliding groove respectively. With the change of the opening angle of the cabinet door 1, the second movable part 9 slides in the strip-shaped sliding groove correspondingly. When the cabinet door 1 is opened to the preset maximum angle, the second movable part 9 will slide to the end opening of the limiting sliding groove 8, and since the diameter of the end opening is greater than the outer diameter of the first sleeve 10, the first sleeve 10 will fall into the end opening to limit the second movable part 9, thus fixing the limiting plate 6, and due to the reverse pulling force of the limiting plate 6, the cabinet door 1 is limited at this time and cannot increase the opening angle.

[0032] Since three mounting holes are designed on the right side of the first mounting strip 2, the limiting plate 6 can be mounted in different hole positions to adjust different opening angle limits.

[0033] The cabinet door supporting structure includes a roller bracket 3 and a roller 4, and the structure is as shown in Figure 1 The roller bracket 3 is fixedly connected with the first mounting strip 2 through screws, the front end of the roller bracket 3 is provided with a roller shaft, and the roller 4 is rotationally connected with the roller shaft. In the process of closing the cabinet door 1, the roller 4 is in rolling connection with the horizontal surface of the second mounting strip 7, thereby providing stable guidance and reliable support for the cabinet door 1.

[0034] In actual use, when the opening angle of the cabinet door is gradually increased, the second movable part 9 moves in the limiting sliding groove 8 towards the end opening, and falls into the end opening when reaching the preset opening angle, and the second movable part 9 is limited by the end opening, thus the position of the limiting rod 6 and the opening angle of the cabinet door 1 are limited correspondingly; if the cabinet door 1 is to be closed, the second movable part 9 is lifted upwards, so that the first sleeve 10 is separated from the end opening. When the cabinet door is closed, the roller 4 is in rolling connection with the horizontal top surface of the second mounting strip 7, thereby providing reliable guidance and support.

[0035] The above is only an embodiment of the present application, and the present application is not limited to the field of the embodiment, and the common knowledge such as specific structures and properties in the scheme is not described in detail. It should be pointed out that for those skilled in the art, without departing from the structure of the present application, a number of modifications and improvements can be made, which should also be considered as the protection scope of the present application, and these will not affect the effect and practicality of the present application. The protection scope claimed in the present application should be subject to the content of the claims, and the specific implementation mode and the like recorded in the specification can be used to explain the content of the claims.
