Description

Technical Field

[0001] The utility model relates to the technical field of door panels of power distribution cabinets, in particular to an alternating current low-voltage incoming line cabinet and a door panel structure thereof. Background Art

[0002] The main components of the incoming line cabinet include vacuum circuit breakers, disconnectors, three sets of three-coil current transformers, lightning arresters, live displays, voltage transformers, wires and other components.

[0003] The door panels of existing distribution cabinets are installed in a relatively simple manner and lack a certain buffering function, which results in their edges colliding with the cabinet body for a long time during use, causing more severe wear at this position than at other positions, thereby reducing the service life of the distribution cabinet.

[0004] Therefore, the present application provides an AC low-voltage incoming line cabinet and a door panel structure thereof to meet the needs. Utility Model Content

[0005] The purpose of the present application is to provide an AC low-voltage incoming line cabinet and a door panel structure thereof, aiming to solve the problem that the door panel lacks an anti-collision function, resulting in a shortened service life of the distribution cabinet.

[0006] To achieve the above-mentioned purpose, the present application provides the following technical solutions: a door panel structure, comprising a cabinet body and a door panel, wherein the door panel is hinged on the cabinet body, an anti-collision box is provided on the top surface of the cabinet body, an anti-collision mechanism is provided in the anti-collision box, and the anti-collision mechanism is connected to the door panel via a connecting column, and the connecting column is a polygonal column;

[0007] The anti-collision mechanism also includes a steering member, an auxiliary plate, and a limit member. A through hole communicating with the outside is provided in the anti-collision box, and a steering member is rotatably connected in the through hole. One end of the connecting column is slidably connected to the hole on the steering member. A slideway is provided next to the through hole, and the slideway is an arc-shaped slideway. The limit member is slidably connected in the slideway. A sliding hole matching the limit member is provided on the steering member, and an auxiliary plate is hinged on the steering member. There are two groups of auxiliary plates, which are symmetrically arranged, and the auxiliary plates are in an "eight" shape. The auxiliary plates are slidably connected to the limit member. A buffer mechanism is provided on the auxiliary plate.

[0008] Preferably, the steering member includes a rotating member and a guiding member. The rotating member is disc-shaped and has a hole in the middle that communicates with each other up and down. The hole is adapted to the connecting column. The outer wall of the steering member is connected to the guiding member. The guiding member is a U-shaped member, and the limiting member is slidably connected in the inner groove of the guiding member.

[0009] Preferably, the limiting member includes a sliding column, a connecting plate, and an adjusting rod. The sliding column is slidably connected in the slideway and the guide member. The top surface of the sliding column is connected to the connecting plate by bolts. The bottom surfaces of both ends of the connecting plate are provided with adjusting rods. The adjusting rod is slidably connected to the outer wall of the auxiliary plate.

[0010] Preferably, the buffer mechanism includes a permanent magnet, a placement hole is provided at the free end of the auxiliary plate, a permanent magnet is provided in the placement hole, and the opposite surfaces of the permanent magnet are of the same pole. The design of the permanent magnet allows the free ends of the two sets of auxiliary plates to approach each other during the movement of the limiter, generating a repulsive force, thereby achieving the purpose of buffering and anti-collision.

[0011] Preferably, the buffer mechanism includes a No. 1 spring, and the free ends of the two sets of auxiliary plates are connected by the No. 1 spring, and the No. 1 spring is a compression spring. The compression spring pushes the free ends of the two sets of auxiliary plates outward, and during the movement of the limiter, it is always pressed outward, thereby generating a buffering effect.

[0012] Preferably, the buffer mechanism includes a No. 2 spring and a connecting member, the connecting member is an L-shaped member and is arranged on the outer wall of the guide member, the guide member is provided with two groups, and is symmetrically arranged, the guide member is connected to the free end of the auxiliary plate through the No. 2 spring, and the No. 2 spring is a tension spring. The tension spring always pulls the auxiliary plate outward, so it plays a buffering role in the process of the limiter moving.

[0013] Preferably, the section of the auxiliary plate is trapezoidal. The trapezoidal design allows the friction of the sliding column to gradually increase during its movement, generating resistance, thereby achieving the purpose of buffering when closing the door panel.

[0014] An AC low-voltage incoming line cabinet comprises the above-mentioned door panel structure.

[0015] In summary, the technical effects and advantages of the utility model are:

[0016] The utility model has polygonal holes on the door panel. The polygonal holes are inserted into the anti-collision box through connecting columns and are connected to the steering member. When the door panel is rotated, the steering member is driven to rotate. The steering member drives the limiting member to move in the slideway and cooperates with the auxiliary plate. When the limiting member slides, the auxiliary plate clamps the limiting member, so that the resistance encountered by the door panel is gradually increased during the flipping process, so that the door panel can be protected from collision when closed, avoiding long-term collision and aggravating strain.

[0017] In the utility model, the sliding column of the limit member slides in the guide member which is shaped as a U-shaped member, and the two groups of auxiliary plates intersecting on the guide member are in an "eight" shape, and the spacing between the hinged ends thereof is smaller than the diameter of the sliding column. Therefore, the sliding column slides during the rotation of the guide member, and the sliding column passes through the adjusting rod and the connecting plate fixed by bolts on the top of the sliding column. During the movement, the auxiliary plates are guided to clamp the sliding column, thereby increasing the damping and preventing the door panel from hitting the cabinet body.

[0018] The utility model can achieve the purpose of buffering and resetting by using three different structures of the buffer mechanism. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0032] 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 in 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.

[0033] Example 1: Reference Figure 1-9 A door panel structure shown includes the following AC low-voltage incoming line cabinet.

[0034] The door panel structure includes a door panel 2, an anti-collision box 3, a steering member 4, an auxiliary plate 5, a limit member 7, and a buffer mechanism; the door panel 2 is hinged on the cabinet body 1, and a polygonal hole is provided at the hinge point of the door panel 2. The cabinet body 1 is provided with holes corresponding to the positions of the polygonal holes. The anti-collision box 3 is arranged above the hole, and is inserted into the polygonal hole through a polygonal connecting column 8, and is inserted into the anti-collision box 3 through the hole on the cabinet body 1. A through hole 31 is provided in the anti-collision box 3, and an arc-shaped slideway 32 tangent to the through hole 31 is provided next to the through hole 31. A steering member 4 is rotatably connected in the through hole 31, and the steering member 4 is adapted to the connecting column 8 to achieve the purpose of connecting the steering member 4 and the door panel 2. The free end of the steering member 4 is slidably connected The limiting member 7 also slides in the slideway 32. The overall shape of the limiting member 7 is E-shaped. Two sets of auxiliary plates 5 are hinged at the free end of the steering member 4. The two sets of auxiliary plates 5 are in an "eight" shape, and the spacing between the hinged ends of the two sets of auxiliary plates 5 is smaller than the diameter of the center axis of the limiting member 7. The auxiliary plate 5 slides in the gap between the center axis and the side axis of the limiting member 7. The door panel 2 and the steering member 4 are vertically arranged. Therefore, when the door panel 2 is flipped, the steering member 4 is driven by the connecting column 8 to rotate the steering member 4. The limiting member 7 moves under the drive of the slideway 32 and the steering member 4, and clamps the auxiliary plate 5. The auxiliary plate 5 clamps the limiting member 7 to increase the resistance and prevent the door panel 2 from hitting the cabinet 1.

[0035] The slide column 71 of the above-mentioned limit member 7 is connected to the connecting plate 72 by bolts, and the two ends of the connecting plate 72 are fixedly connected with adjusting rods 73. The adjusting rod 73 is the side axis mentioned above, and the slide column 71 is the central axis mentioned above. The auxiliary plate 5 is slidably connected between the slide column 71 and the adjusting rod 73. Therefore, when the slide column 71 moves in the slideway 32, from the beginning to the end, it gradually approaches the edge of the through hole 31 and clamps the auxiliary plate 5 to clamp the slide column 71, increase the resistance, and prevent the door panel 2 from hitting the cabinet 1.

[0036] The rotating member 41 of the steering member 4 is disc-shaped, and its cross-section is T-shaped. The guide member 42 is a U-shaped structure. The rotating member 41 is rotatably connected in the through hole 31. The guide member 42 is connected to the rotating member 41. The sliding column 71 slides inside the guide member 42, and the top surface of the guide member 42 is hinged with an auxiliary plate 5.

[0037] A buffer mechanism is provided on the auxiliary plate 5, which cooperates with the above structure to achieve the purpose of resetting and buffering.

[0038] In this embodiment, a placement hole 51 is provided at the free end of the auxiliary plate 5, and a permanent magnet 6 is installed in the placement hole 51. The opposite magnetic poles of the two groups of permanent magnets 6 are the same. During use, the closer they are, the greater the repulsive force is, thereby achieving the purpose of buffering.

[0039] Embodiment 2: This embodiment differs from Embodiment 1 in that:

[0040] like Fig.10 As shown, the buffer mechanism of this embodiment is provided with a No. 1 spring 9 on the opposite sides of the two groups of auxiliary plates 5. The No. 1 spring 9 is a compression spring. Therefore, when in use, the free ends of the two groups of auxiliary plates 5 are close to each other, squeezing the compression spring to achieve the buffering purpose.

[0041] Embodiment 3: This embodiment differs from Embodiment 1 in that:

[0042] like Fig.11 As shown, the buffer mechanism of this embodiment is provided with an L-shaped connecting member 10 on the outer wall of the guide member 42, and the connecting member 10 is connected to the auxiliary plate 5 through a No. 2 spring 11. The No. 2 spring 11 is a tension spring. Therefore, during the movement of the auxiliary plate 5 during the limit member 7, the free end of the auxiliary plate 5 gradually approaches, and the tension spring plays a reaction force to achieve the buffering purpose.

[0043] The practical working principle of the present invention is as follows: when closing the door panel 2, the door panel 2 rotates on the cabinet body 1 through the connecting column 8, and drives the steering member 4 in the anti-collision box 3 to rotate in the through hole 31. The rotating steering member 4, whose rotating member 41 is adapted to the connecting column 8 through the polygonal hole, is driven to rotate by the door panel 2, and then the rotating rotating member 41 drives the guide member 42 connected thereto to rotate, and the guide member 42 drives the slide column 71 of the limit member 7 to slide in the slideway 32 through the internal space. In the process of movement, the slide column 71 gradually approaches the through hole 31, and at the same time, the slide column 71 drives the auxiliary plate 5 hinged on the guide member 42 to move through the provided connecting plate 72 and the adjusting rod 73. The free end of the auxiliary plate 5 gradually shortens the distance and clamps the slide column 71, thereby increasing the damping, buffering the speed of the door panel 2, and reducing the impact between the door panel 2 and the cabinet body 1.

[0044] When the auxiliary plate 5 approaches, the free end of the auxiliary plate 5 is disposed on the permanent magnet 6 in the placement hole 51. The opposite surfaces of the auxiliary plate 5 are disposed with the same poles, so repulsion is generated when the auxiliary plate 5 approaches, thus playing a buffering role.

[0045] The working principle of the second embodiment is that when the free ends of the auxiliary plates 5 are close to each other, a spring 9 provided between the free ends of the auxiliary plates 5 exerts an outward force to produce a buffering effect.

[0046] The working principle of Example 3 is that when the free end of the auxiliary plate 5 approaches, the connecting piece 10 provided on the guide member 42 is connected to the free end of the auxiliary plate 5 through the No. 2 spring 11, which makes the tension spring pull outward when the auxiliary plate 5 approaches, thereby achieving a buffering effect.

[0047] The electromechanical connection involved in the present utility model is a common means used by those skilled in the art, and technical inspiration can be obtained through a limited number of tests, which belongs to common knowledge.

[0048] Components not described in detail herein are prior art.

[0049] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
