Description

Technical Field

[0001] The utility model relates to the technical field of power distribution cabinets, in particular to a cabinet door of a power distribution cabinet. Background Art

[0002] The connection structure of the door of the power distribution cabinet is generally connected by hinges or hinges, so that the door can be rotated to open the power distribution cabinet. The design of the existing power distribution cabinet is relatively closed, resulting in poor heat dissipation and the need for regular maintenance of the power distribution cabinet. Based on the above heat dissipation and maintenance requirements, in actual use, the door needs to be opened to a certain angle and kept open at that angle.

[0003] In order to fix the cabinet door at an opening angle, the patent document with the announcement number CN217589858U discloses a distribution cabinet door with a fixed angle, including: a distribution cabinet body, a cabinet opening is provided on the right side of the distribution cabinet body, the cabinet opening is convex, and the top of the cabinet opening is connected to the cabinet door body through a hinge; the top of the cabinet body is fixedly connected with a connecting block, the right side of the connecting block is connected to a movable cylinder through a hinge, the right side of the movable cylinder is an opening structure, the inside of the opening is inserted with a movable rod, the left side of the movable rod is inserted into the inside of the movable cylinder, and is fixedly connected with a moving block, the top and bottom of the inner wall of the movable cylinder are provided with a plurality of grooves, the upper end face and the lower end face of the moving block are fixedly connected with a convex block, the convex block is inserted into the inside of the groove, and the right side of the movable rod is connected to the cabinet door body through a hinge.

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] See also Figure 1-9 The utility model provides a door of a power distribution cabinet, comprising a cabinet body 10 and a door 20 hinged to the cabinet body 10, wherein the door 20 is hinged to the cabinet body 10 by a hinge, so that the door 20 can be opened outwards 180°. The door of the power distribution cabinet also comprises a first track 1 arranged in the cabinet body 10, a first slide 2 slidably arranged on the first track 1, a second track 3 arranged on the door 20, a second slide 4 slidably arranged on the second track 3, a turning rod 5 arranged on the second slide 4, and a connecting rod 6 respectively hinged to the first slide 2 and the turning rod 5, a first positioning mechanism 7 for locking the position of the first slide 2 is provided on the first slide 2, and a second positioning mechanism 8 for the position of the second slide 4 is provided on the second slide 4; the turning rod 5 comprises a first rod 51 and a second rod 52, and the angle between the first rod 51 and the second rod 52 is 90° to 180°. In one embodiment, the angle between the first rod 51 and the second rod 52 is preferably 90°.

[0030] When the cabinet door 20 is opened, the first slide 2 slides along the first track 1, and the second slide 4 slides along the second track 3. When the cabinet door 20 is opened to a certain angle, the first positioning mechanism 7 and the second positioning mechanism 8 are locked respectively to fix the first slide 2 on the first track 1, and the second slide 4 on the second track 3. Figure 2 As shown, the cabinet door 20 is in a closed state; Figure 3As shown, the second slide 4 is located at one end of the first track 1 away from the hinge between the cabinet door 20 and the cabinet body 10. When the first slide 2 moves along the first track 1 toward the hinge between the cabinet door 20 and the cabinet body 10, the maximum positioning angle of the cabinet door 20 is 90°; Figure 4 As shown, the first slide 2 is located at one end of the first track 1 close to the hinge between the cabinet door 20 and the cabinet body 10. When the second slide 4 moves along the second track 3 toward the hinge between the cabinet door 20 and the cabinet body 10, the positioning angle of the cabinet door 20 is in the range of 90° to 180°. Compared with the prior art, the range of the cabinet door 20 that can be opened at a fixed angle is increased, which is conducive to the development of maintenance work.

[0031] In a preferred embodiment, see Figure 6 , a first slide groove 11 is provided in the first track 1, a first slide seat 2 is slidably connected to the outer side of the first track 1, and a plurality of first rollers 21 slidably connected to the first slide groove 11 are rotatably connected to the first slide seat 2. Specifically, a groove matching the first track 1 is provided in the first slide seat 2, the first slide seat 2 is sleeved outside the first track 1, and can slide on the first track 1. Preferably, there are two first rollers 21, the two first rollers 21 are rotatably connected to one side of the first slide seat 2, and the first rollers 21 slide in the first slide groove 11, so that the first slide seat 2 slides along the first track 1 and is not easy to separate from the first track 1.

[0032] Specifically, see Fig. 9 , stoppers 12 are respectively provided at both ends of the first track 1 to prevent the first roller 21 from escaping from the first slide groove 11 .

[0033] In a preferred embodiment, see Figure 5 The first positioning mechanism 7 includes a first vertical shaft 71 disposed on the first slide 2, and a first cam 72 rotatably connected to the first vertical shaft 71. The first slide 2 is provided with a first avoidance hole 22. The first cam 72 passes through the first avoidance hole 22 and abuts against the outer side of the first track 1 to lock the position of the first slide 2 on the first track 1. By rotating the first cam 72, the wheel surface away from the rotation center of the first cam 72 abuts against the outer side of the first track 1 to fix the position of the first slide 2 on the first track 1; conversely, when the wheel surface close to the rotation center of the first cam 72 turns to the outer side of the first track 1, there is a gap between the wheel surface and the outer side of the first track 1, and at this time, the position of the first slide 2 on the first track 1 can be adjusted.

[0034] Further, see Figure 5 The first cam 72 is provided with a shifting block 73 for facilitating the rotation of the first cam 72 . By shifting the shifting block 73 , the first cam 72 is driven to rotate around the axis of the first vertical shaft 71 .

[0035] Specifically, one end of the shift block 73 close to the first cam 72 is a cylindrical insert 731 , and the first cam 72 is provided with a socket 721 that matches the insert 731 . The insert 731 is inserted into the socket 721 to achieve the connection between the shift block 73 and the first cam 72 .

[0036] Optionally, the dial block 73 has a curved surface 732 which is conducive to the finger moving the dial block 73 , and the curvature of the curved surface 732 is similar to the curvature of the fingertips of human fingers, thereby improving the comfort of moving the dial block 73 .

[0037] Furthermore, a rubber layer is provided on the outer wall of the first cam 72 to increase the friction between the first cam 72 and the outer side of the first track 1 , thereby improving the stability of the positioning of the first slide seat 2 .

[0038] In this embodiment, refer to Figure 5 , 7 , a second slide groove 31 is provided in the second track 3, a second slide seat 4 is slidably connected to the outer side of the second track 3, and a plurality of second rollers 41 slidably connected to the second slide groove 31 are rotatably connected to the second slide seat 4; specifically, the second slide seat 4 is sleeved outside the second track 3 and can slide along the second track 3, specifically, there are two second rollers 41, and the two second rollers 41 slide in the second slide groove 31, so that the second slide seat 4 slides along the second track 3 and is not easy to be separated from the second track 3. The second positioning mechanism 8 includes a second vertical shaft 81 provided on the second slide seat 4, and a second cam 82 rotatably connected to the second vertical shaft 81, a second avoidance hole 42 is provided on the second slide seat 4, and the second cam 82 passes through the second avoidance hole 42 and abuts against the outer side of the second track 3 to lock the position of the second slide seat 4 on the second track 3. Specifically, the end of the first rod 51 of the turning rod 5 is installed on the second slide seat 4, and the end of the second rod 52 is hinged to the connecting rod 6. By providing the turning rod 5 , the cabinet door 20 can be opened at an angle ranging from 90° to 180°, thereby avoiding position interference between the connecting rod 6 and the cabinet door 20 when the cabinet door 20 is opened at a large angle.

[0039] It should be noted that, in another embodiment, when the opening angle of the cabinet door 20 is greater than 180° (when the cabinet body 10 and the cabinet door 20 do not interfere with each other), the angle between the first rod 51 and the second rod 52 can be set to an obtuse angle, or on the same straight line, and the position of the first slide 2 on the first track 1 and the position of the second slide 4 on the second track 3 are adjusted accordingly, so that the cabinet door 20 can be positioned in a state where the opening angle is greater than 180°.

[0040] In the above, the structure of the second positioning mechanism 8 is similar to that of the first positioning mechanism 7, and the specific working principle can refer to the first positioning mechanism 7. When locking the second slide 4, the second cam 82 is rotated to make the wheel surface of the second cam 82 away from the axis of the second vertical shaft 81 abut against the outer side of the second track 3, so as to achieve locking the second slide 4 on the second track 3.

[0041] In this embodiment, when the cabinet door 20 is in the closed state, the first slide 2 is located at one end of the first track 1 away from the connection between the cabinet door 20 and the cabinet body 10, and the second slide 4 is located at one end of the second track 3 away from the connection between the cabinet door 20 and the cabinet body 10, and the first positioning mechanism 7 cancels the position lock of the first slide 2, and the second positioning mechanism 8 cancels the position lock of the second slide 4, so as to ensure that the cabinet door 20 can be smoothly opened in the next operation. However, in the actual process, the first cam 72 and the second cam 82 are prone to rotate due to vibration, so that their wheel surfaces correspondingly abut on the first track 1 and the second track 3, resulting in the cabinet door 20 being unable to open normally.

[0042] Further, see Figure 8 The first slide 2 is provided with a through hole 23, and a limiting rod 9 for limiting the position of the shifting block 73 is slidably connected to the through hole 23. When the limiting rod 9 is inserted into the through hole 23, the shifting block 73 cannot be shifted, so that the wheel surface close to the rotation center of the first cam 72 always faces the outside of the first track 1, thereby ensuring that the first slide 2 can slide along the first track 1.

[0043] For further information, see Figure 8 , 9 , the first slide 2 is provided with a fixed seat 91, the limiting rod 9 is slidably connected with the fixed seat 91, the limiting rod 9 is sleeved with a spring 92, the limiting rod 9 is provided with a retaining ring 93 abutting against the spring 92, the two ends of the spring 92 are respectively abutted against the fixed seat 91 and the retaining ring 93, under the elastic force of the spring 92, the limiting rod 9 is kept in the state of limiting the action of the shifting block 73; the peripheral wall of the limiting rod 9 is provided with a convex strip 94 extending along its length direction, and the through hole 23 is provided with a notch 24 corresponding to the convex strip 94, the convex strip 94 is pulled up, and rotated by an angle, the spring 92 contracts, the convex strip 94 is away from the notch 24, so that the convex strip 94 can be kept in the state of being pulled up, at this time, the shifting block 73 can be randomly shifted. On the contrary, the limiting rod 9 is rotated so that the convex strip 94 corresponds to the position of the notch 24, and under the elastic force of the spring 92, the limiting strip moves downward, and the position of the shifting block 73 is limited again.

[0044] In a preferred implementation, see Figure 5One end of the connecting rod 6 is rotatably connected with a screw 61, and the screw 61 is threadedly connected to the first slide 2. Under the action of the screw 61, the connecting rod 6 is rotatably connected to the first slide 2. When the first slide 2 or the second slide 4 is moved, the connecting rod 6 rotates around the axis of the screw 61. When the screw 61 is unscrewed, the connecting rod 6 can be removed from the first slide 2 to release the connection between the first slide 2 and the turning rod 5. At this time, the cabinet door 20 can be opened to any angle and cannot be positioned at this angle to be used as the cabinet door 20 in the prior art.

[0045] It is understandable that those skilled in the art can make equivalent substitutions or changes based on the technical solution and the utility model concept of the utility model, and all these changes or substitutions should fall within the protection scope of the utility model.
